ADJUSTABLE DOUBLE INTERNAL LIMIT STOP FOR ROLLER VENEZIANAS
Cross reference to related orders [0001] This is a non-provisional pending US provisional patent application serial number 62 / 408,291, filed on October 14, 2016, entitled Adjustable Internai Double Limit Stop for Roller Shades, the entirety of which order is incorporated here as a reference.
Field of disclosure [0002] This disclosure relates, in general, to sets of architectural coatings and, more particularly, to a system and method for providing multiple travel limits for sets of architectural coatings.
Fundamentals of Disclosure [0003] Coatings for architectural openings, such as windows, doors, arches and the like, have taken on numerous forms over the years. Some known sets of architectural coatings include a flexible coating, such as fabric attached to a rotating roller that is movable between an extended position and a retracted position. A drive mechanism allows a user to raise and lower the flexible liner by rolling the liner in or out of the rotating roller. To avoid thrusting or blocking the liner and / or the drive mechanism, some known liner assemblies include positive stops located in the lower corners of the flexible liner. These stops fit into the respective stops on the headboard or end caps to which the rotating roller is attached to provide a physical limit to the elevated position of the liner and to prevent the liner from being excessively rolled up on the rail. In addition, some
Petition 870170077761, of 11/10/2017, p. 8/68
2/32 coverings included a single stop at the head and / or inside the rotating rail itself to provide a limit on the lowered position of the cover. The positive stops at the bottom corners of the flexible material can be effective, but some consumers don't like their appearance.
Summary [0004] It would be desirable to provide a system with extension and retraction displacement limits for a roller shutter, in which the mechanism for providing such displacement limits is arranged entirely within the roller tube. In some embodiments, the first travel limit can be adjustable, either by an installer or consumer, while the second travel limit can be a fixed position that is not adjustable by the installer or the user. Allowing an installer or user to adjust the first travel limit can be useful to accommodate the seating of the fabric, or consumer preferences for making fine adjustments to the final position of the shutter on your window. The second travel limit can be adjusted and set at the factory before the final assembly of the system and therefore will not be adjustable by the installer or the consumer. In one embodiment, the adjustable limit can be adjusted by inserting a tool through an opening in the end plate, disengaging a portion of the limit set and then activating the tool. The actuation can facilitate the adjustment of the stop position to the adjustable limit, thus adjusting the total amount of extension that the shutter can undergo. In some embodiments, a release tool can be provided to disengage the adjustable limit so that the roller shutter can be freely adjustable, which may be desirable during the manufacture of the shutter.
[0005] As mentioned, the entire displacement limit mechanism can be arranged internally to the roll tube and
Petition 870170077761, of 11/10/2017, p. 9/68
3/32 to the end plate, thus eliminating problems related to external limit devices (for example, low reliability, undesirable cosmetics, poor fit and space consumption).

Detailed Description [0033] The following description is intended to provide modalities of non-limiting examples of the disclosed system and method, and these example modalities should not be interpreted as limiting or more desirable than other modalities that may represent one or more principles disclosed in that document. A person skilled in the art will understand that the steps and methods disclosed can be easily reordered and manipulated in many configurations, as long as they are not mutually exclusive. As used in this document, one and one may refer to a single or a plurality of items and should not be interpreted as exclusively singular, unless explicitly indicated.
[0034] The description will proceed in relation to an architectural structure, which, without limitation, can be an opening, such as a window, an entrance, an arcade or something like that. It will be appreciated that references in an architectural opening / structure are made for convenience and with no intention of limiting the present disclosure to a specific structure.
Petition 870170077761, of 11/10/2017, p. 12/68
6/32 [0035] Some known architectural cladding sets may include a flexible cladding, such as fabric attached to a rotating roll tube. The liner can be raised or lowered by rolling the liner into or out of the rotating roller via a drive mechanism operatively coupled to the roller tube. The physical limits for the raised and / or lowered positions of the cover can be provided to avoid blocking the drive mechanism and to prevent the coating from curling or overlapping.
[0036] In the raised / retracted position, the liner can be rolled up on the roll tube, while in the lowered / extended position the liner can be unwound from the roll tube. A first limit stop may be disposed within the roll tube and can prevent the roll tube from wrapping the liner in the tube when the liner has reached a desired raised position. A second limit stop can also be disposed within the roll tube and can prevent the roll tube from unwinding the tube cover once the cover has reached the desired lowered position.
[0037] FIG.1 shows an example of an embodiment of an architectural cladding assembly 100 that includes a non-limiting example travel limit assembly in accordance with the present disclosure. The liner assembly 100 includes a headboard 108, which, in the form of the illustrated embodiment, is a casing with opposite end caps 110, 112 joined at the front, rear and top sides to form an open bottom casing. Headboard 108 also has assemblies 114 for coupling headboard 108 to a structure above an architectural opening, such as a wall, by means of mechanical fasteners, such as screws, rivets, etc. A roll tube 104 is rotatably coupled between end caps 110, 112. Although a specific example of a headboard 108 is shown in FIG.1,
Petition 870170077761, of 11/10/2017, p. 13/68
7/32 many different types and styles of main headboards exist and can be used in place of the exemplary headboard of FIG.1.
[0038] In the example shown in FIG.1, the liner 106 is a unitary sheet of flexible material 116 having an upper edge 117 coupled to the roll tube 104 and a lower free edge 119. However, it will be appreciated that other arrangements assembly are within the scope of this disclosure. The cover 106 is movable between a retracted position and an extended position (illustratively, the position shown in FIG.1). When in the highest position, the liner 106 is wrapped around the roll tube 104. Although not shown, a mechanism actuator can be provided to move the liner between the raised and lowered positions. The drive mechanism can take any appropriate shape (for example, a clutch, a gear, an engine, a transmission train and / or a gear train, etc.) and can include any type of controls (for example, continuous loop , raise / lower cord (s), chains, ropes, etc.).
[0039] FIG.2 shows a non-limiting travel limit assembly 120 to adjust and limit the amount of extension and retraction that the roll tube 104 and cover 106 can undergo in operation. Such limits can provide both aesthetic and operational benefits. As will be appreciated, from an aesthetic point of view, it may be desirable to place a retraction limit on the liner 106 so that, in the fully retracted position, a portion of the liner remains visible near the top of the architectural opening. It may also be desirable to provide an extension limit on the liner 106 so that, in the fully extended position, the bottom end of the cover settlement at a desired distance above a structural bottom aspect of the architectural opening (for example, a sill) . From an operational point of view, the limits of extension and retraction of settlement
Petition 870170077761, of 11/10/2017, p. 14/68
8/32 can prevent locking or blocking of the cover and / or the drive mechanism.
[0040] Example travel limit set 120 includes an end plate 122, first and second limit screws 124, 126, first and second limit nuts 128, 130 and a bushing 132. The first and second limit screws 124, 126 are, during the normal operational extension and retraction of the roll tube 104, rotatably fixed in relation to the end plate 122. The first and second limit nuts 128, 130 can be threaded with external threads of the first and second screws limit 124, 126 and can be rotatably fixed in relation to the roll tube 104 (FIG.1). The bushing 132 can be positioned directly adjacent to the end plate 122 and can also be fixed in relation to the roller tube 104 so that, as the roller tube 104 rotates, the bushing 132, as well as the first and second limit nut 128, 130, can rotate with respect to end plate 122 and the first and second limit screw 124, 126. It will be appreciated that end plate 122 is optional and that the disclosure may cover other elements in relation to which the first and / or second limit screws 124, 126 can be rotatably fixed or rotatable with respect to it.
[0041] Since the first and the second limit nut 128, 130 are rotatably fixed in relation to the roll tube 104, as the roll tube rotates to extend or retract the casing 106, the first and second nut limit plate moves axially along the respective first and second limit screws 124, 126. The rotation of the roll tube 104 will continue unimpeded until one of the first and second limit nuts 128, 103 finds a stop surface 134 , 136 which, in the illustrated embodiment, comprises surfaces arranged in predetermined positions on the first and second limit screws 124, 126. When the first or second limit nut 128, 130
Petition 870170077761, of 11/10/2017, p. 15/68
9/32 engages a respective first or second stop surface, 134, 136, further rotation of the roll tube 104 is prevented so that the liner 106 cannot extend (or retract).
[0042] It will be appreciated that, in common use, one of the first and second limit nut 128, 130 can serve as a retraction limit, while the other of the first and second limit nut can serve as an extension limit . It will also be appreciated that by adjusting the initial positions of the first and second limit nut 128, 130 along the lengths of the first and second limit screw 124, 126, the total distance that each nut can travel before engaging in a stop surface of the associated limit screw can be adjusted. Since the travel distance of each nut along its associated limit screw is proportional to a number of revolutions of the roll tube 104, adjusting the position of the limit nuts on the limit screws proportionally adjusts the total number of revolutions of the roller tube 104 and the cover 106 are allowed to undergo in the directions of extension and retraction. As a result, adjusting the initial positions of the first and second limit nut 128, 130 on the first and second limit screw 124, 126 allows the extension and retraction limits for roll tube 104 and liner 106 to be adjusted.
[0043] Now, with reference to FIGS.3 and 4, the interrelationship between elements of the example displacement limit set 120 will be described in more detail. In general, the example travel limit assembly 120 includes the first limit screw 124 and end plate 122 which are rotatably fixed relative to each other, but which allow selective disengagement to thereby allow rotation of the first limit screw 124 and thus the adjustment of the first limit nut 128 with respect to a stop surface 134 of the first limit screw. As can be seen, in FIG.3 shows the travel limit assembly 120 without the roll tube 104, while FIG.4
Petition 870170077761, of 11/10/2017, p. 16/68
10/32 shows the assembly in the context of the roll tube 104. As shown, in addition to the elements described with reference to FIG. 2, the travel limit assembly 120 may include an axis 138 having a first end 140 coupled (for example , fixed axially and rotatably) to the end plate 122. The shaft 138 can, among other things, serve to support the first and second limit screws 124, 126 and the roller tube 104 on the end plate 122.
[0044] As best seen in FIG.4, axis 138 and the first and second limit screws 124, 126 can have a nested configuration in which axis 138 is received within the first limit screw 124 and a portion of the second limit screw 126 is received within a portion of the first limit screw 124. Specifically, the shaft 138 can be received within a hole 142 of the first limit screw 124 so that, when assembled, a first end 144 of the first limit screw 124 is capable of positioning directly adjacent to end plate 122. As will be discussed in more detail below, the positioning of a first end 144 of the first limit screw 124 directly adjacent to end plate 122 allows radially oriented projections inward 176 of the first limit screw 124 engages in the projections radially oriented outwardly correspondingly 178 of the axis to rotatively fix those of the is in relation to each other.
[0045] A second end 146 of the axis 138 may be disposed adjacent to a second end 148 of the first limit screw 124 and may be received within a hole 150 in a first end 152 of the second limit screw 126 such that a end surface 154 of shaft 138 abuts an internal shoulder 156 disposed in hole 150 in the second limit screw. As will be described in more detail below, this backrest, in combination with a lock 158, axially locks axis 138 to the second limit screw
Petition 870170077761, of 11/10/2017, p. 17/68
11/32
126. The first end 152 of the second limit screw 126 can also be received into the hole 142 in the second end 148 of the first limit screw 124 such that the connection between axis 138 and the second limit screw 126 exists within the hole of the first limit screw 124 as well. As will be described in more detail below, the axis 138 and the second limit screw 126 may have aspects configured to prevent the relative rotation in the interim once the two are engaged. Thus, when assembled, the shaft 138 and the second limit screw 126 can be fixed axially and rotatably to each other.
[0046] A fastener 158 can couple the shaft 138 with the second limit screw 126 and the end plate 122. In the illustrated embodiment, the fastener 158 is a screw, although it is contemplated that other fastening arrangements can also be used without away from disclosure. The closure 158 may have a head portion 160 disposed in the hole 150 of the second limit screw 126 and a body portion 162 disposed in a hole 164 of the shaft 138. An end portion 166 of the fastener 158 can be received within a projection 168 of the end plate 122. The head portion 160 of the fastener 158 can abut the inner shoulder 156 of the second limit screw 126 so that, when tightened, the head extracts the second limit screw 126 in fixed fit with respect to the surface end 154 of the shaft 138. At the same time, the second limit screw 126 and the shaft 138 are extracted in fixed engagement with the end plate 122. Tightening the fastener 158 completely, axially and rotationally locks the shaft 138 and the second screw limit 126 on end plate 122.
[0047] As can be better seen in FIG. 4, a spring 170 can be arranged around the second end 146 of the axis 138, inside the hole 142 of the first limit screw 124. The spring 170 can also be positioned between a end surface 172
Petition 870170077761, of 11/10/2017, p. 18/68
12/32 of the second limit screw 126 and an internal shoulder 174 disposed in hole 142 of the first limit screw 124. Since the second limit screw 126 is fixed axially in relation to the end plate 122, the spring 170 can abut the first limit screw 124 towards the end plate 122.
[0048] As mentioned earlier, during operation it is desirable that the first and second limit bolts 124, 126 are rotatably fixed as the roll tube 104 rotates so that the first and second nut 128, 130 can rotate move along the limit screws as the first and second limit nut 128, 130 rotate with the roll tube 104. As described, the second limit screw 126 can be fixed against rotation because it is attached to the end plate end 122. The first limit screw 124 can be rotationally fixed via one or more radially inwardly oriented projections 176, formed at the first end 144 of the first limit screw 124 which are interlockable with corresponding radially outwardly oriented projections 178 formed at the first end 140 of axis 138. It will be appreciated that the illustrated arrangement of the cooperating projections 176, 178 is an example of an arrangement for fixing rot actively the first limit screw 124 in relation to axis 138 and that other arrangements are within the scope of the disclosure. Since the axis 138 is fixed rotationally with respect to the end plate 122, in the configuration shown in FIG.4, the first limit screw 124 is fixed rotationally with respect to the end plate 122 through the axis 138. As will be described in more detail later, the projections 176, 178 of the first limit screw 124 and axis 138 can, in some cases, be disengaged from each other to allow the first limit screw 124 to be rotated in relation to the axis.
Petition 870170077761, of 11/10/2017, p. 19/68
13/32 [0049] As shown further in FIGS.3 and 4, the bushing 132 can support one end of the roller tube 104 so that it rotates together with the roller tube 104. The bushing 132 can have an internal surface 180 that it slides against, as it rotates with respect to, the first end 144 of the first limit screw 124 and may have a plurality of external ribs 182 to engage an inner surface 184 of the roll tube 104. Thus arranged, the bushing 132 and the roll 104 are rotatable with respect to end plate 122.
[0050] As mentioned earlier, the first and second limit nut 128, 130 of the illustrated non-limiting example are rotatably fixed relative to the roll tube 104 so that they rotate as the roll tube rotates. Thus, the first and the second limit nut 128, 130 may have the respective tube stop surfaces 186, 188, which in the illustrated embodiment comprise respective recesses that engage in a longitudinally oriented projection 190 formed on the inner surface 184 of the tube of roller. The first and second limit nuts 128, 130, each include inner strands 192, 194 (FIGS.11A, 11B) dimensioned and shaped to engage the outer strands 196, 198 of the first and second limit screws 124, 126 Thus, as mentioned, when the roll tube 104 is rotated to extend or retract the liner 106, the first and second limit nut 128, 130 also rotate and, due to their threaded interaction with the first and second screw of limit 124, 126, they move along the limit screws 124, 126, respectively, until they find a stop.
[0051] The first and second limit nuts 128, 130 include respective first and second stop surfaces 200, 202, which are configured to engage the respective first and second stop surfaces 134, 136 of the first and second limit screws. . For convenience, FIGS.5A and 5B show only the fit of the first
Petition 870170077761, of 11/10/2017, p. 20/68
14/32 limit 128 and the first limit screw 124. As illustrated in FIG.5A, as the first limit nut 128 rotates in the direction indicated by arrow A, the first limit nut also moves in the direction of arrow B towards the end plate 122. If the roll tube 104 continues to be rotated, the stop surface 200 of the first limit nut 128 will eventually engage with the stop surface 134 of the first limit screw 124, and the engagement of the stop will prevent further rotation of the nut (and consequently, the roll tube 104 and cover 106). This may represent a retraction limit or an extension limit for cover 106.
[0052] In the illustrated embodiment, the external threads 196, 198 of the first and second limit screws 124, 126 are opposite hand. Although not shown, it will be appreciated that such an arrangement results in the first and second limit nut 128, 130 which moves away from each other or towards each other as the roller tube 104 rotates in a particular direction. As such, the stop surfaces 134, 136 of the first and second limit screws 124, 126 are positioned closest to the first ends 144, 152 of the first and second limit screws. However, this arrangement is not crucial and other thread and stop arrangements can be used.
[0053] As will be appreciated, by adjusting the initial positions of the first and second limit nuts 128, 130 on the first and second limit screws 124, 126 in relation to the respective stop surfaces 134, 136, the total number of complete revolutions that the limit the nuts can suffer before one of the nuts engages a respective stop surface can be adjusted. Since the first and the second limit nut 128, 130 are fixed in rotation with respect to the roll tube 104, the disclosed arrangement allows to adjust the total amount of extension or retraction that the cover 106 connected to the roll tube 104 can undergo.
Petition 870170077761, of 11/10/2017, p. 21/68
15/32 [0054] FIG. 6 illustrates an example of end plate 122 which includes a plate portion 204, a headrest portion 206, a projection 168 and a tool receiving opening 208. The socket portion headboard 206 is configured to fit headboard 108 shown in FIG.1. The protrusion 168 can be configured to be received inside the hole 164 of the shaft 138 and can receive the end portion 166 of the lock 158 to couple the shaft 138 and the second limit screw 126 to the end plate 122 in the manner previously described in relation to to FIG.4. As will be described in more detail below, the tool receiving opening 208 may be arranged adjacent to the protrusion 168 so that a tool end can be inserted to adjust a system extension or retraction limit.
[0055] With reference to FIGS. 7A and 7B, the axis 138 may have the first and second ends 140, 146 and the longitudinal hole 164 to receive the closure 158 in the middle. The first end 140 can include a plurality of radially disposed projections 178 for engaging corresponding projections of the first limit screw 124 as previously described. The second end 146 of the shaft 138 may have a series of projections 208 configured to engage correspondingly shaped recesses 212 (FIG.9B) formed at the first end 152 of the second limit screw 126. This engagement serves to rotatively lock the second limit screw 126 to axis 138.
[0056] FIGS.8A-8C show the first limit screw 124 having the first and second ends 144, 148, the external threads 196, the hole 142 and the stop surface 134 as previously described. The orifice 142 can be dimensioned to receive the axis 138 and the first end 152 of the second limit screw 126 therein. Visible within orifice 142 is the internal shoulder 174 described in relation to FIG. 4. As mentioned, this internal shoulder 174 is
Petition 870170077761, of 11/10/2017, p. 22/68
16/32 insertable with one end of the spring 170 to tilt the first limit screw 124 towards the end plate 122. The projections 176 radially oriented inwardly are arranged adjacent to the first end 144 of the first limit screw 124, so that are interlockable with projections oriented 178 out of axis 138. As will be appreciated, the arrangement described for engaging and inhibiting rotation movement between axis 138 and the first limit screw 124 is just one example, and other configurations for engaging the shaft and the first limit screw to inhibit relative rotation are within the scope of this disclosure.
[0057] FIGS.9A and 9B show the second limit screw 126 having the first and second ends 152, 214, external threads 198, the hole 150, and the stop surface 136 as previously described. Visible within the orifice 150 is the internal shoulder 156 described in relation to FIG. As mentioned, this internal shoulder 156 abuts the end surface 154 of the shaft 138. In addition, the end surface 172 disposed at the first end 152 of the second limit screw 126 is interlockable with an end of the spring 170 to tilt the first lock screw. limit 124 towards the end plate 122. The recesses 212 are shown arranged adjacent to the first end 152 of the second limit screw 126 and are interlockable with the outwardly projected projections 208 formed at the second end 146 of the axis 138. As will be appreciated, the described arrangement for engaging and inhibiting rotation movement between axis 138 and the first limit screw 126 is just an example, and other configurations for engaging the axis and the first limit screw for inhibiting relative rotation are within the scope of present disclosure.
[0058] FIGS.10A, 10B show the first and second limit nut 128, 130, which include respective internal threads 192, 194 dimensioned and molded to engage the external threads 196, 198 of the
Petition 870170077761, of 11/10/2017, p. 23/68
17/32 first and second limit screws 124, 126. The first and second stop surfaces 200, 202 comprise projections dimensioned and shaped to engage the respective first and second stop surfaces 134, 136 of the first and second stop screws. limit. The tube engaging surfaces 186, 188 comprise respective recesses which are sized and positioned to receive and slide along a longitudinally oriented projection 190 (FIG.4) formed on the inner surface 184 of the roller tube 104.
[0059] Now, with reference to FIGS.11-14, an aspect of adjustment of the path limit set 120 will be described in more detail. As can be seen in FIG.11, the end plate 122 includes a tool receiving opening 208 positioned adjacent the first end 140 of the shaft 138. This tool receiving opening 208 exposes a portion of the first end 144 of the first screw. limit 124 so that a tool 216 (FIG. 13) can be inserted to fit the first limit screw 124. Tool 216 can be used to move the first limit screw 124 axial and rotational with respect to axis 138 to adjust the extension or retraction limit for roll tube 104 and liner 106. When disengaging (for example, axially) the first limit screw 124 from shaft 138 and end plate 122, the first limit screw and the first limit nut 128 can rotate together, along with the roll tube 104 and the casing 106. Once an adjusted extension or retraction position of the cover 106 is achieved, the tool 216 can be removed from the and so that the first limit screw 124 is again rotatably locked to the axis 138 and to the end plate 122 through the interaction of projections 176, 178 of the first limit screw and axis, respectively.
[0060] FIG. 12 shows a path boundary set 120 configuration in which the first boundary screw 124 is in a
Petition 870170077761, of 11/10/2017, p. 24/68
18/32 position rotatably locked in relation to axis 138. In this position rotatably locked, the radially inwardly oriented projections 176 formed at the first end 144 of the first limit screw 124 are engaged with the radially oriented outward projections 178 formed at the first end 140 of the axis 138 and, as such, the first limit screw 124 is rotatably locked to the axis 138 (and therefore the end plate 122). As will be appreciated, the configuration of FIG. 12 is the operational configuration of the path limit set 120. Thus, in this configuration, the roll tube 104 and the liner 106 can be extended and retracted as limited by the first and second limit nut 128, 130 according to the positions of initial adjustment of the limit nuts on the first and second limit screws 124, 126.
[0061] As mentioned, it may be desirable to allow an installer or user to adjust the extension or retraction limit to suit a particular architectural opening size or to suit a user's taste. Thus, the revealed path limit set 120 includes a feature in which the position of the first limit nut 128 can be adjusted along the length of the first limit screw 124 without disassembling the headrest 108 or any portion of the path limit set .
[0062] FIG. 13 shows the path limit set 120 in an adjustment setting. As can be seen, a tool 216 (which in the non-limiting example is a Phillips head screwdriver) was inserted through the tool receiving opening 208 in the end plate 122 and coupled to an end surface 218 adjacent to the first end 144 of the first limit screw 124. In general, tool 216 can disengage the first limit screw 124 from axis 138, such as by moving the first limit screw 124 with respect to axis 138 so that the first limit screw 124 rotate in relation to axis 138. In the illustrated mode, the tool
Petition 870170077761, of 11/10/2017, p. 25/68
19/32
216 can be used to move the first limit screw axially with respect to axis 138. As shown, moving tool 216 in the direction of arrow C overcame the slope in spring 170 and has caused the first limit screw 124 to move in the arrow direction D to a rotatable unlocked position in which the radially inwardly oriented projections 176 formed at the first end 144 of the first limit screw 124 are no longer engaged with the corresponding radially outwardly oriented projections 178 formed at the first end 140 of the axis 138 As can be seen, when the first limit screw 124 assumes the rotatable unlocked position, the spring 170 is compressed from an initial length SL1 (FIG.11) to a shorter length SL2 as the first limit screw moves in the direction of arrow D (ie towards the second limit screw 126).
[0063] In this rotatable unlocked position, the first limit screw 124 is free to rotate with respect to axis 138. FIG. 14 shows the interactive engagement of the ribs 220 of the tool 216 with the projections radially inwardly 176 formed at the first end 144 of the first limit screw 124. Rotating the tool 216 in the direction of the arrow Έ causes the ribs 220 to fit into the projections 176 of the first limit screw 124 and thus cause the first limit screw 124 to rotate in the same direction. In some embodiments, this rotation adjustment can occur while the stop surface 200 of the first limit nut 128 is engaged with the corresponding stop surface 134 of the first limit screw 124 (i.e., the configuration shown in FIG.5B). Thus, the rotation of tool 216 can cause the limit nut 128 and roll tube 104 to rotate to retract or extend the casing 106 by a desired amount.
Petition 870170077761, of 11/10/2017, p. 26/68
20/32 [0064] As will be appreciated, the liner 106 is either extended or retracted depending on the rotation direction of the tool 216 and the hand on the threads 196 of the first limit screw 124. Once a desired extended or retracted position of the liner has been achieved 106, tool 216 can be removed, after which the first limit screw 124 can return to the locked rotation position, as can be done by the tilting force of spring 170. The radially inwardly oriented projections 176 formed in the first end 144 of the first limit screw 124 can engage again with corresponding projections radially oriented outwardly 178 formed at the first end 140 of axis 138, again rotatingly locking the first limit screw 124 to axis 138 (and therefore the plate end 122). The travel limit assembly 120 can then function as described previously to limit the extension and retraction of the roll tube 104 and the liner 106, with the newly adjusted path limit implemented.
[0065] FIGS.15A-C illustrate a release feature of the disclosed path limit set 120. In some embodiments, it may be desirable to rotationally disengage the first limit screw 124 from axis 138 so that it can rotate freely for ease manufacturing process 106 and / or other aspect of the system. The release feature can be implemented using a structured tool to hold the first limit screw 124 in a disengaged position with respect to axis 138, so that the stop position between the first limit screw 124 and the first limit nut 128 can be adjusted freely and indirectly (for example, without directly accessing or moving the nut / stop), such as adjusting the length of the liner and rotating the roll tube. In the illustrated embodiment, a release tool 222 may have a body portion 224, a longitudinal projection portion 226 and a hook portion 228
Petition 870170077761, of 11/10/2017, p. 27/68
21/32 arranged in the longitudinal projection portion. A user who grasps the body portion 224 can insert the hook portion 228 through the tool receiving opening 208 in the end plate 122 until the hook portion engages the end surface 218 of the first limit screw 124. Press the tool release 222 against end surface 218 overcomes the slope on spring 170 and causes the first limit screw 124 to move in the direction of arrow D to the rotationally unlocked position in which the projections 176 of the first limit screw 124 are unlocked projections 178 of shaft 138. The hook portion 228 of the release tool 222 can rest on a correspondingly shaped flange surface 230 of shaft 138, which can serve to temporarily lock the release tool in position and lock the first locking screw. limit 124 in the unlocked rotation position. The first limit screw 124 can then be rotated freely together with the first limit nut 128 and the roller tube 104. In some embodiments, this free rotation can occur while the stop surface 200 of the first limit nut 128 is engaged with the corresponding stop surface 134 of the first limit screw 124 (i.e., the configuration shown in FIG.5B). Thus, when the roll tube 104 and cover 106 are freely rotated to assume a desired fully retracted or fully extended position and the release tool 222 is disengaged from the path limit set 120, the adjustable path limit is adjusted in that position . It will be appreciated that the illustrated modality is just an example of an implementation of a release tool and release arrangement, and it is contemplated that other tools and techniques can be implemented without departing from the scope of the disclosure.
[0066] FIGS.16 - 19 show an alternative arrangement of a path limit assembly 240 that includes an end plate 242, first and second limit screws 244, 246, first and second
Petition 870170077761, of 11/10/2017, p. 28/68
22/32 limit nuts 248, 250, bushing 252 and spring 254.0 path limit set 240 also includes a coupling 256 for removably coupling the first and second limit screws 244, 246 together. The path limit set 240 may include some or all of the characteristics of the path limit set 120 described in relation to FIGS.2-15C, except that the first limit screw 244 of this embodiment remains rotatable and axially fixed in relation to the plate end plate 242, while the second limit screw 246 is selectively adjustable, both axially and rotationally, with respect to the end plate.
[0067] Thus, except when otherwise described, the first and second limit screws and the first and second limit nuts of the path limit set 240 may have some or all of the same characteristics described in relation to the previous modality, including external thread, internal thread, roll tube engagement surface and stop surfaces.
[0068] The first limit screw 244 may have a first end 258 which is fitted to end plate 242 through a groove 260 in an end plate protrusion 262 within which a projection 264 (FIG. 18) on the first screw limit limit 244 can fit. This keyed interaction prevents relative rotation between the first limit screw 244 and end plate 242. The first limit screw 244 can have a second end 266 that fits into a hole in a first end 268 of the second end screw. limit 246. As best seen in FIG. 17, the first and second limit screws 244, 246 can be rotatably coupled to each other through corresponding grooves 271, 273 formed at the second end 266 of the first limit screw 244 and the first end 268 of the second limit screw. It will be appreciated that the illustrated key arrangement is just one example of a way in which the first limit screw 244 is rotatably attached to
Petition 870170077761, of 11/10/2017, p. 29/68
23/32 with respect to end plate 242, and it is contemplated that other appropriate provisions can be implemented without departing from the scope of the disclosure.
[0069] As shown in FIG. 18, coupling 256 may be partially arranged in an orifice 270 of the first limit screw 244 and partially arranged in an orifice 272 of the second limit screw 246. A lock 274 disposed in the hole 272 of the second limit screw 246 may have a portion head 276 which engages an internal shoulder 278 of the second limit screw and a body portion 280 which engages a recess 282 in coupling 256. Lock 274 can secure coupling 256 axially and rotationally in relation to the second screw limit 246. A spring 254 can be arranged between a shoulder 284 of coupling 256 and an internal shoulder 286 of the first limit screw 244 to tilt the second limit screw 246 to engage with the first limit screw 244.
[0070] As with the embodiment of FIGS.2-15C, the path limit set 240 of FIGS.16-19 includes an aspect that allows an installer or user to adjust the roll tube extension or retraction limit 104 and coating 106 to suit a particular architectural opening size, or to suit a user's taste. The revealed path limit set 240 includes a feature in which the cover extension or retraction limit 106 can be adjusted without disassembling or disengaging headboard 108 or any part of the path limit set.
[0071] FIG. 18 shows a configuration of the path limit assembly 240 in which the second limit screw 246 is in a position rotatably locked with respect to the end plate 242. In this position rotatably locked, the grooves 272 of the second limit screw are engaged with the grooves 270 of the first limit screw 244 and thus the second limit screw 246 is locked
Petition 870170077761, of 11/10/2017, p. 30/68
24/32 rotatably on the end plate 242. This configuration represents the operational configuration of the path limit set 240. Thus, in this configuration, the roll tube 104 and the liner 106 can be extended and retracted as limited by the first and second limit nut 248, 250 according to the initial adjustment positions of the limit nuts on the first and second limit screws 244, 246.
[0072] FIG.19 shows the trajectory limit set 240 in an adjustment configuration. As can be seen, a tool 280 (which in the illustrated example of non-limiting example is a Phillips head screwdriver) was inserted through a tool receiving opening 282 in end plate 242 and a recess 284 is coupled to a first end 286 of coupling 256. Moving tool 280 in the direction of arrow F overcomes the polarization in spring 254 and causes the second limit screw 246 to move in the direction of arrow F to a rotationally unlocked position in which keys 272 of the second limit the screw 246 is no longer involved with the keys 270 of the first limit screw 244. In this rotationally unlocked position, the second limit screw 246 is free to rotate in relation to the first limit screw 244 and the end plate 242. With the second limit screw 246 in the rotatable unlocked position, the rotation of the tool 280 in the direction of the arrow G causes the coupling 256 to rotate, causing q u and the second limit screw rotates in the same direction.
[0073] In some embodiments, this rotation adjustment can take place on a stop surface 249 (FIG.17) of the second limit nut 250 is engaged with the corresponding stop surface 247 of the first limit screw 246. Thus, rotation of the tool 280 can cause the second limit screw 246, the second limit nut 250 and the roller tube 104 to rotate, extending or retracting the cover 106 to a desired amount. As will be appreciated, the
Petition 870170077761, of 11/10/2017, p. 31/68
25/32 coating 106 is either extended or retracted depending on the direction of rotation of the tool 280 and the hand on the threads 245 of the second limit screw 246. As will be appreciated, the direction of translation can be controlled according to the direction of rotation of the tool 280 and the thread handle 245 of the second limit screw 246.
[0074] Once a desired translation has been achieved, tool 280 can be removed, after the second limit screw 246 can move in relation to the first limit screw 244 to rotatively lock the two together. In the illustrated embodiment, removal of tool 280 may allow the polarizing force of spring 254 to cause the second limit screw 246 to move axially back toward the rotationally locked position such that the keys 270, 272 of the first and second limit screws 244 246 return to the engagement. This rotationally locks the second limit screw 246 to the first limit screw 244 and end plate 242 again. The travel limit assembly 240 can then function as described previously to limit the extension and retraction of the roll tube 104 and coating 106, with the newly adjusted trajectory limit implemented.
[0075] The inventive material claimed is directed to an architectural cover assembly 100 that includes a rotating roller tube 104 and a cover 106 coupled to the rotating roller tube. The liner 106 is movable between an extended position and a retracted position. The assembly also includes an end plate 122, an axis 138 that has a first end 140 coupled to the end plate and a first end screw 124 that has a hole 142, where at least a portion of the axis is disposed within the hole. A second limit screw 126 has a first end 152 coupled to a second end 146 of axis 138 and the first end of the second limit screw is received into hole 142 of the first limit screw 124. One

26/32 the first limit nut 128 is coupled to the rotating roller tube 104 so that it rotates with the rotating roller tube. The first limit nut 128 is threaded with external threads 196 of the first limit screw 124. A second limit nut 130 is coupled to the rotating roll tube 104 so that it rotates with the rotating roll tube. The second limit nut 130 is also threadedly engaged with external threads 198 of the second limit screw 126. The first limit screw 124 is selectively rotationally movable about the axis 138 to adjust an extension or retraction limit of the casing 106.
[0076] The inventive material claimed is also directed to an architectural cover assembly 100 that includes a rotating roller tube 104 and a cover 106 coupled with the rotating roller tube. The liner 106 is movable between an extended position and a retracted position. The assembly also includes an end plate 242 and a first limit screw 244 having first and second ends 258, 266 and a hole. The first end 258 is coupled to the end plate 242. A second end screw 246 has a first end 268 and also has a hole for receiving the second end 266 of the first end screw 244. A coupling 256 is received into holes 271 , 273 of the first and second limit screws 244, 246, and the coupling is fixed axially and rotationally with respect to the second limit screw. Coupling 256 is movable rotationally and axially with respect to the first limit screw 244. A first limit nut 248 can be coupled to the rotating roller tube 104 so that the first limit nut rotates with the rotating roller tube. The first limit nut 248 is also engaged threaded with external threads 243 of the first limit screw 244. A second limit nut 250 is coupled to the rotating roller tube 104 so that the second limit nut rotates with the rotating roller tube. . The second limit nut 250 is threaded with external threads 245 of the second

27/32 screw 246. The second limit screw 246 is selectively movable between a locked rotation position and an unlocked rotation position in relation to the first limit screw 244. In the locked rotation position, a 270 projection of the first limit screw 244 is capable of engagement with a projection 272 of the second limit screw 246 to prevent relative rotation between them. In the rotationally unlocked position, the projection 272 of the second limit screw 246 is axially separated from the projection 270 of the first limit screw 244 to allow the second limit screw 246 to rotate with respect to the first limit screw to adjust an extension or retraction limit of the coating 106.
[0077] The inventive material claimed is also directed to an architectural cover assembly 100 that includes a rotating roller tube 104 and a cover 106 coupled with the rotating roller tube. The liner 106 is movable between an extended position and a retracted position. The set also includes an end plate 122; 242 and first and second limit screws 124, 126; 244, 246 each having respective first and second ends. The second end of the first limit screw 124; 244 is attachable to the first end of the second limit screw 126; 246. One of the first and second limit screws 124, 126; 244, 246 is fixed rotationally and axially with respect to end plate 122; 242 and the other one between the first and second limit screws is movable between a rotationally locked position and a rotationally unlocked position in relation to the end plate 122; 242. A first limit nut 128; 248 is coupled to the rotating roller tube 104 and is threaded with external threads of the first limit screw 124; 242.

28/32 between the first and second limit screws is fixed axially and rotationally in relation to the end plate 122. In the rotationally unlocked position, the other of the first and second limit screws 124, 126; 244, 246 is rotatably movable with respect to end plate 122; 242 to adjust a coverage extension or retraction limit 106.
[0078] The inventive material claimed is also directed to an architectural coating assembly 100 that includes a rotating roller tube 104 and a cover 106 coupled to the rotating roller tube, wherein the cover is movable between an extended position and a retracted position . The set also includes a limit screw 124; 246 having the first and second ends 144, 148; 268, and a limit nut 128; 250 coupled to the rotating roller tube 104. The limit nut 128; 250 is engaged threaded with external wires 196; 245 of limit screw 124; 246. The limit screw 124; 246 is selectively movable between a position rotatable with respect to the rotating roller tube 104 and a position rotationally unlocked with respect to the rotating roller tube. In the rotationally unlocked position, the limit screw 124; 246 is rotatable in relation to the rotating roller tube 104, while in the rotatively locked position the limit screw 124; 246 is rotatable with the rotating roller tube to adjust a cover extension or retraction limit 106.
[0079] The inventive material claimed is also directed to a method of adjusting an extension or retraction limit of an architectural cover set 100. In some non-limiting examples, the architectural cover set 100 includes a rotating roller tube 104 and a cover 106 coupled to the rotating roller tube, wherein cover 106 is movable between an extended position and a retracted position. The set also includes an end plate 122; 242 a limit screw 124; 246 having the first and second ends 144, 148; 268, and a
Petition 870170077761, of 11/10/2017, p. 35/68
29/32 limit nut 128; 250 coupled to the rotating roller tube 104, where the limit nut is engaged with thread with external wires 196; 246 of limit screw 124; 246. The method includes displacement of a limit screw 124; 246 from a position rotatably locked with respect to end plate 122; 242 to a position rotatably unlocked with respect to the end plate; turning the limit screw 124; 246 to rotate the limit nut and the rotating roller tube 104, where the rotation of the rotating roller tube extends or retracts the cover. When moving the limit screw 124; 246 from the position rotatable relative to the end plate 122; 242 to the position rotatable in relation to the end plate defines a limit of extension or retraction of the cover 106.
[0080] In some claimed modalities, when the limit screw 124; 246 is in the pivotally unlocked position with respect to end plate 122; 242, the rotating roller tube 104 is rotated (for example, pulling the liner 106) to adjust the position of the liner. When desired positioning of the liner 106 is achieved, the limit screw 124; 246 is returned to the position rotatably locked with respect to end plate 122; 242 which thereby establishes a limit for extension or retraction of the liner 106.
[0081] In an exemplified, non-limiting embodiment claimed, the limit screw 124 is moved from the rotationally locked position to the rotatable unlocked position of a tool 216 with a surface 218 of the limit screw 124. Tool 216 includes flutes 220 for fitting a projection 176 of the limit screw 124, so that the rotation of the limit screw rotates the flutes, which in turn rotate the projection and also rotate the rotating tube of the roll 104 to extend or retract the casing 106. In other exemplary non-limiting modalities, the
Petition 870170077761, of 11/10/2017, p. 36/68
30/32 limit screw 124 is moved from the rotatingly locked position to the rotatingly unlocked position of a release tool 222 with the surface 218 of the first limit screw 124. The release tool 222 has, in a non-limiting example, a hook end 228 to hold the limit screw 124 in the rotatable unlocked position so that the first limit screw can rotate freely with respect to the end plate 122. As mentioned, the rotating roller tube 104 is then rotated (for example, pulling the liner 106) to adjust the liner position. When a desired positioning of the liner 106 is achieved, the limit screw 124 is returned to the position rotatable in relation to the end plate 122 with the release of the release tool 222; which, in this way, establishes a limit of extension or retraction of the coating 106.
