[0001] This application claims priority to n2Taiwan Patent Application 101106084 filed on February 23, 2012; and Patent Application No. 2U.S. 13 / 484,530 deposited on May 31, 2012. BACKGROUND 1. Field Of Invention
[0002] The present inventions refer to blinds and control modules used for the actuation of blinds. 2. Description of the Related Art
[0003] Many types of blinds are currently available on the market, such as blinds, roller blinds and honeycomb blinds. The blind when lowered can cover the area of the window frame, which can reduce the amount of light that enters the room through the window and provides greater privacy. Conventionally, the blind is equipped with an operating rope that can be actuated to raise or lower the blind. In particular, the operating rope can be pulled down to raise the blind and released to lower the blind.
[0004] In a conventional blind construction, the operating rope can be connected with a driving shaft. When the operating rope is pulled down, the drive shaft can rotate to wind the suspension ropes to raise the blind. When the operating rope is released, the drive shaft can be driven to turn in a reverse direction to lower the blind.
[0005] However, this conventional construction may require the use of an increased length of the operating rope for blinds that have longer vertical lengths. The longer length of the operating rope can affect the external appearance of the blind. In addition, there is a risk that a child may be strangled on a longer operating rope. To reduce the risk of accidental injury, the operating rope can be held in a higher position so that a small child cannot easily reach the operating rope. Unfortunately, when the operating rope is pulled down to raise the blind, the operating rope can still move to a lower position and become accessible to a child.
[0006] For a regular user, handling longer operating ropes may also be less convenient. For example, the longest operating rope can become entangled, which can make it difficult to operate.
[0007] Therefore, there is a need for a blind that is convenient to operate, safer to use and that covers at least the following problems. SUMMARY
[0008] The invention describes a blind and a control module suitable for use with the blind. The construction of the control module can use a shorter length of an operating rope to lift a shade structure from the blind. The control module also includes an actuator that is easily operable to change the control module from a locking state to an unlocking state to lower a bottom part of the blind.
[0009] In one embodiment, the blind control module comprises a drive shaft, a sleeve attached to the drive shaft, a retainer mounted around the drive shaft, and a release unit. The retainer has a locking state in which the retainer blocks a rotational displacement of the sleeve and drive shaft to retain a shade shading structure for the desired position, and an unlocking state in which the rotation of the sleeve and drive shaft is allowed to lower the shading structure by gravity. The release unit includes an actuator that is operatively connected to the retainer and has an elongated shape that extends substantially vertically, defining a longitudinal geometric axis, where the actuator is operable to rotate around the longitudinal geometric axis to change the retainer from the locking state to the unlocking state.
[0010] In another embodiment, a blind is described. The blind comprises a main rail, a shading structure, a bottom part arranged at a lower end of the shading structure, a plurality of suspension ropes connected with the main rail and the bottom part, a plurality of winding units of rope mounted with the main rail and connected with the suspension ropes and a control module mounted with the main rail. The control module includes a drive shaft mounted with the units of a retainer mounted around the drive shaft and a release unit. The retainer has a locking state in which the retainer blocks a rotational displacement of the sleeve and drive shaft to keep the bottom part in a desired position and an unlock state in which rotation of the sleeve and drive shaft is allowed to lower the bottom part by gravity. The release unit includes an actuator that is operatively connected to the retainer and has an elongated shape that extends substantially vertically that defines a longitudinal geometric axis, where the actuator is operable to rotate around the longitudinal geometric axis to change the retainer from the locking state to the unlocking state.
[0011] At least one advantage of the blind described in this document is the ability to conveniently adjust the blind by operating the operating string and the actuator respectively. The operating rope used to lift the blind is shorter in length, which can reduce the risk of child strangulation. The blind can also be lowered easily by turning the actuator.

[0046] Figure 1 is a perspective view illustrating an embodiment of a blind 110. Blind 110 can include a main rail 112, a shading structure 114 and a bottom part 116 arranged at the bottom of the shading structure 114. To operate the shading structure 1 14 and the bottom part 11 16 operatively, the blind 110 may include a control module 124, a plurality of suspension strings 126 (shown with dashed lines) and a plurality of winding units of rope 128. Control module 124 may include a drive shaft 118, an operating rope 120 (shown with dashed lines) and an actuator 122. Each suspension rope 126 can be mounted between the main rail 112 and the bottom 116, a first end portion of the suspension rope 126 being connected with a rotating drum of an associated winding unit 128 and a second end portion of the suspension rope 126 being connected with the bottom part 116. The shading structure 114 can be retracted upwards by lifting the bottom part 116 towards the main rail 112. To lift the bottom part 116, the operating rope 120 can be pulled in movement, which can be transmitted and converted through the control module 124 into a rotation of the drive shaft 118 and the rotating drum (not shown) of each length of the corresponding suspension rope 126 between the main rail 112 and the bottom part 116.
[0047] By operating the actuator 122, the control module 124 can also be changed to a release or unlock state in which the drive shaft 118 can be allowed to rotate. When the control module 124 is in this state of release, the bottom part 116 itself can be lowered by gravity, which causes the suspension ropes 126 to unwind from the respective rope winding units 128 and expand the shading structure 114. Shutter 110 can thus be changed to a shaded state or closed. Exemplary operations and constructions of control module 124 will now be described with reference to the additional drawings.
[0048] Various constructions may be applicable to make the shading structure 114. For example, the shading structure 114 may include a honeycomb structure made of a fabric material, a shutter construction, or a plurality of rails or slats that extend vertically and parallel to each other.
[0049] The main rail 112 can be of any type and shape. The main rail 112 can be arranged on a top of the blind 110 and can be configured to mount the drive shaft 118 and the control module 124. The bottom part 116 is arranged on a bottom of the blind 110. In one embodiment, the part bottom 116 can be formed as an elongated rail. However, any types of weighing structures can be suitable. In some embodiments, the bottom portion 116 may also be formed by a lower portion of the shading structure 114.
[0050] The drive shaft 118 can define a geometrical drive axis and can be connected respectively with the rope winding units 128 and the control module 124. The displacement of the bottom part 116 is operatively connected with the actuation of the drive shaft 118, that is, the rotation of drive shaft 118 is operatively connected with the up and down movements of the bottom part 116. In one embodiment, the rotating drum of each rope winding unit 128 can be attached with the drive shaft 118, so that the rope winding units 128 can rotate synchronously together with the drive shaft 118 to wind and unwind the suspension ropes 126. It should be noted that the rope winding units 128 can be made from any suitable or conventional constructions. In addition, the drive shaft 118 is also operatively connected to the control module 124, so that the drive shaft 118 can be driven in rotation by operating the operating rope 120 to lift the shading structure 114.
[0051] The construction of the blind 110 can be so that a user can pull the operating rope 120 to lift the shading structure 114. In one embodiment, the operating rope 120 can be of a length that is shorter than one total permissible stroke of the bottom part 116. The user can repeatedly apply a sequence of pull and release actions on the operating rope 120 to progressively lift the shading structure 114. For example, the overall length of the operating rope 12 0 can be less than half the height of the fully expanded shading structure 114. In another example, the length of the operating string 120 can be one third of the height of the fully expanded shading structure 114, and the operating string 120 can be pulled repeatedly approximately three times to fully lift the shading structure 114. This process is similar to a ratchet technique that allows the user to pull the operating rope tion 12 0 to raise the shading structure 114 by a certain amount, allow the operating rope 120 to retract, and then pull the operating rope 120 again to continue to raise the shading structure 114. This process can be repeated until the shading structure 114 reaches a desired height.
[0052] In addition, actuator 122 can be rotated operatively to change control module 124 from a locking state to a release state to allow rotation of the drive shaft 118 so that the bottom part 116 can to lower yourself due to its own weight. When the actuator 122 is released, the control module 124 can change from the release state to the locking state to block the rotation of the drive shaft 118.
[0053] Figures 2 and 3 are exploded and cross-sectional views, respectively, illustrating a modality of control module 124. Control module 124 may include a retainer 132, a release unit 134, a rope drum 136 and a latch 138. The control module 124 can additionally include a spring 140 operable to drive the rotation of the rope drum 136 in one direction to wind the operating rope 12 0. The spring 140 can be arranged inside (as shown) or outside control module 124.
[0054] In addition, control module 124 may include housing 142 and cover 144. Housing 142 and cover 144 can be assembled together to form a housing in which the component parts of control module 124 can be assembled .
[0055] The cover 144 may have an inner side provided with a guide wheel 14 5 around which the operating rope 120 can be in contact and can be guided in motion.
[0056] The coupling 138 can be operable to couple and uncouple the movements of the rope drum 136 and the drive shaft 118. When the coupling 13 8 is in the uncoupled state, the driving shaft 1 18 and the rope drum 136 can rotate relative to each other. For example, the rope drum 136 can remain stationary, and the weight of the bottom part 116 and the shading structure 114 stacked on it can drive the drive shaft 118 in rotation relative to the rope drum 136, which causes the shading structure 114 and bottom part 116 are lowered. Alternatively, the drive shaft 118 can remain stationary and the rope drum 136 can rotate to wind and receive the operating rope 120. By pulling the operating rope 120, the latch 138 can be switched to the coupling state. In the coupling state of the coupling 138, the rope drum 136 and the driving shaft 118 can rotate synchronously through the movement transmission through the coupling 138 to lift the shading structure 114 and the bottom part 116.
[0057] The coupling 138 can be mounted around a fixed rod 146 between the retainer 132 and the rope drum 136. In one embodiment, the coupling 138 can include a first coupling 150, a second coupling 152, a spring 154, a connecting member 156 and a bearing part 160. The bearing part 160 can be, for example, a ball. The latch 138 may additionally include a sleeve 161.
[0058] With reference to Figures 3 to 5, the connecting member 156 can be attached with the fixed rod 146. The fixed rod 146 can be separated from the driving shaft 118. More specifically, the fixed rod 146 can extend from the cover 144 coaxial to the drive shaft 118. The first coupling 150 can be pivotally connected to a portion of the fixed rod 146 and the second coupling 152 can be pivotally connected to the connecting member 156. The first and second couplings 150 and 152 they can rotate around the common axis of the drive shaft 118 and the fixed rod 146 in relation to the fixed rod 146 to change the coupling 138 to the coupling or uncoupling state.
[0059] Referring to Figure 4, the first coupling 150 can have a generally cylindrical shape, and combine with the second coupling 152. More particularly, the first coupling 150 can have an outer surface 162 of a cylindrical shape defined between two portions of far end. The outer surface 162 may include a recessed portion that extends along the periphery of the first coupling 150 and at least partially defines a guide track 164 of the engagement 138 and one or more notches 165 that communicate with the guide track 164. In one embodiment, two slots 165 can be provided diametrically opposite. The first coupling 150 may have a first end portion close to the rope drum 136 provided with two opposite radial flanges 150A. The rope drum 136 can make contact with the radial flanges 150A, so that the rotation of the rope drum 136 can drive the first coupling 150 to rotate.
[0060] The first coupling 150 may have a second end portion next to the second coupling 152 provided with at least one radial stop 168 which is located adjacent to the notch 165. In one embodiment, two radial stop 168 can be provided in two opposite locations on the outer surface of the first coupling 150 respectively adjacent to the notches 165.
[0061] The first coupling 150 can additionally include at least one slot 169 separate from the radial abutments 168. In one embodiment, two slits 169 can be provided at diametrically opposite locations of the first coupling 150 respectively adjacent to the radial abutments 168.
[0062] Referring to Figure 5, the second coupling 152 may have a generally cylindrical shape, and may combine with the first coupling 150. The second coupling 152 may have two radial ribs 172 diametrically opposite each other. Each radial rib 172 may have an outer surface 174 and an extension 176. Extension 176 may extend radially from radial rib 172 towards the center of the second coupling 152.
[0063] As shown in Figure 14, after the first and second couplings 150 and 152 are assembled together, a closed guide track 164 can be formed between the outer surface 162 of the first coupling 150 and the outer surface 174 of the second coupling 152 The guide track 164 can run peripherally around the first and second couplings 150 and 152. Each radial rib 172 can be movably arranged adjacent to a corresponding notch 165 of the first coupling 150. Extension 176 can be inserted prominently in a corresponding slot 169 to guide the relative movement between the first and second couplings 150 and 152. Accordingly, the radial ribs 172 can move respectively in the slots 165 to form or remove a plurality of stop regions 177 in the guide trail path 164 (as best shown in Figures 18 and 19).
[0064] Together with Figures 2 and 3, Figures 6 and 7 are schematic views that illustrate sleeve 161. Sleeve 161 can be generally cylindrical in shape and can be attached with drive shaft 118, so that sleeve 161 can rotate together with the drive shaft 118. The sleeve 161 can include a central cavity 178 and a radial slot 179. The radial slot 179 can be formed on an inner side wall of the central cavity 178 and can extend linearly parallel to the axis geometry of the driving shaft 118. When the coupling 138 is mounted, the first and second couplings 150 and 152 can be arranged in the central cavity 17 8, so that the guide track 164 can overlap at least partially with the length of the slot radial 179 and the bearing part 160 can be arranged on the guide track 164 and the radial slot 179.
[0065] When the hitch 13 8 is in the uncoupled state, the relative positions of the first and second couplings 150 and 152 can be such that a rotation of the drive shaft 118 and sleeve 161 independent of the rope drum 13 6 can cause that the bearing part 160 moves along the radial slot 179 and the guide track 164 in relation to the couplings 150 and 152 and the sleeve 161.
[0066] When the coupling 138 is in the coupling state, the second coupling 152 can rotationally move to a second position in relation to the first coupling 150 in order to form the stop regions 177 of recessed shapes in the guide track 164 The stop regions 177 can be formed respectively as recesses in the areas of the slots 165, bounded by at least one side wall of the guide track 164 (shown in Figure 18). Accordingly, the bearing part 160 can move along the guide track 164 and radial slot 179 and then enter and stop at a stop region 177. As a result, the rotation of the rope drum 136 can be transferred through the first and second couplings 150 and 152 and through the restricted bearing part 160 to the sleeve 161 and the driving shaft 1 18. In some variant embodiments, the coupling 138 can also directly transfer the rotation of the rope drum 136 to the drive shaft 118.
[0067] Together with Figure 2, Figures 8 and 9 are schematic views that illustrate the assembly of a portion of the control module 124 (including the rope drum 136 and sleeve 161). The rope drum 136 can be generally cylindrical in shape. The rope drum 136 can be pivotally connected to the fixed rod 146 and can be arranged adjacent to one side of the first coupling 150 opposite the second coupling 152. The rope drum 136 can be connected to the operating rope 120, so that a rotation of the rope drum 136 can wind the operating rope 120 therein. An end portion of the rope drum 136 next to the first coupling 150 may have at least one radial flange 136A. The radial flange 136A can make contact with the flange 150A of the first coupling 150 in order to drive the rotation of the coupling 138.
[0068] Referring to Figures 2 and 3, the rope drum 13 6 can be coupled with the spring 14 0. The spring 140 can tilt the rope drum 136 in a rotational direction to wrap the operating rope 120 around the rope drum 136. The spring 140 can be, for example, a torsion spring mounted in an internal cavity of the rope drum 136. The torsion spring can have a first end affixed with the tie rod 146 and a second end affixed with the rope drum 136. The rope drum 136 can be driven by tilting the torsion spring to rotate with respect to the fixed rod 146 for winding the operating rope 120. In other embodiments, the spring 140 can be mounted outside the control module 124 and can be used to drive the reverse rotation of the rope drum 136: in this case, although the spring 140 is separate from the control module 124, it can remain or be connected to the rope drum 136 to activate the rotation of the same to enr inspect the operating rope 120.
[0069] Together with Figure 2, Figures 10 and 11 are schematic views that illustrate the assembly of the retainer 132 and the release unit 134. The retainer 132 can be mounted around the drive shaft 118 and can rotate in relation to the axis X-axis geometry of drive shaft 118. Retainer 132 may have a locking state and a release or unlock state. In the locking state, retainer 132 can be tightened on sleeve 161 to lock sleeve 161 and drive shaft 118 in position. The rotation of the sleeve 161 and the drive shaft 118 can be blocked in this way and the shading structure 114 and the bottom part 116 can be retained in a desired position. In the release or release state, retainer 132 can relax and allow rotation of sleeve 161 and drive shaft 118 so that the shading structure 114 and bottom part 116 can be lowered by gravity. In one embodiment, retainer 132 may include a spring 180, for example, a wrapping spring. The spring 180 can be cylindrical in shape and can wrap around a peripheral surface of the sleeve 161. The spring 180 can include the first and second pins 180A and 180B extending radially outwardly. The first pin 180A can be attached with the housing 142 and the second pin 180B can be attached with a collar 182. The spring 180 can tighten on the sleeve 161 in the locking state and loosen in the unlocked state.
[0070] The release unit 134 can be connected with the retainer 132 and can be operable to activate the retainer 132 to switch from the locking state to the unlocking state. In one embodiment, the release unit 134 may include a collar 182, the transmission members 184 and 186 and the actuator 122. The collar 182 may be circular in shape. However, other shapes may be suitable, for example, a semicircular shape, a curved shape and the like. Collar 182 can be pivotally connected between sleeve 161 and rope drum 136, more particularly between sleeve 161 and first coupling 150. Collar 182 can rotate about the X axis of rotation of the driving shaft 118. Collar 182 can also be formed with a hole 182A and a toothed portion 182B. The second pin 180B of the spring 180 can pass through the hole 182A to affix with the collar 182.
[0071] Transmission members 184 and 186 are rotating transmission parts that can have different and non-parallel pivot geometric axes and can be mounted on a movement transmission chain between collar 182 and actuator 122. In one embodiment, the transmission members 184 and 186 may have separate pivot geometry axes that are substantially perpendicular to each other. The pivot geometry axis of the transmission member 184 can be substantially parallel to the geometry axis of the driving axis 118 and the pivot geometric axis of the transmission member 186 can be inclined with respect to a vertical geometric axis. The transmission member 184 may have a first portion provided with teeth 188 which can engage with toothed portion 182B. A second portion of the transmission member 184 may engage the transmission member 186 via a gear transmission 190. Examples of gear transmission 190 may include a helical gear, worm gear and the like.
[0072] In one embodiment, the transmission member 186 may have a hollow body. The operating rope 120 can extend from the rope drum 136, can travel through the transmission member 186 and can be routed through the interior of the actuator 122. The operating rope 120 can move in relation to the actuator 122, for example, the operating rope 120 when pulled down can slide along its hollow interior in relation to the actuator 122.
[0073] With reference to Figures 1, 2 and 10, the actuator 122 can have an elongated shape that extends vertically downwards from the main rail 112. For example, the actuator 122 can be formed of a stick or rod. Actuator 122 can be mounted on one side of main rail 112 and can be operatively connected with retainer 132 through collar 182 and transmission members 184 and 186. Operator rope 120 can extend across the interior of the actuator 122 and may have a lower end provided with a plug 192. Plug 192 may abut against a lower end of actuator 122 in order to prevent the operating cord 120 from separating completely from actuator 122 when it moves upwards . The actuator 122 can have an upper end pivotally connected with the transmission member 186 (for example, through a transverse pivot rod), so that the actuator 122 can rotate with respect to the transmission member 186 to adjust the slope actuator 122. In addition, actuator 122 can rotate around the longitudinal geometric axis Y itself to trigger the rotation of the transmission members 184 and 186, which in turn can actuate the retainer 132 to switch from the locking state to the state of unlocking.
[0074] When the operating rope 12 0 is not manipulated by a user, the spring 180 can be tightened around the sleeve 161 to block the rotation of the driving shaft 118. The shading structure 114 can thus be retained in a position fixed by the locking action of the retainer 132. It should be noted that the sleeve 161 can be formed as any part of any shape that is mounted with the drive shaft 118 and can be operatively connected with the coupling, and should not be limited elements mounted with the driving shaft. In other embodiments, the sleeve 161 can also be integrally formed with the driving shaft 118 and the spring 180 can be tightened on the driving shaft 118 to block its rotation.
[0075] Figures 11 and 12 are schematic views that illustrate the operation of the release unit 134. When a user wishes to lower the bottom part 116, the actuator 122 can be gently rotated to trigger a rotational displacement of the collar 182 around the X axis of rotation of the driving shaft 1 18 through the transmission members 184 and 186, which in turn cause the second pin 180B to move the spring 180. The retainer 132 can thus change from the locking state to the state of unlocking.
[0076] Together with Figures 1 to 12, Figure 13 is a schematic view illustrating an operation for lowering the blind 110, and Figure 14 is a schematic view illustrating a configuration of the guide track 164 on the hitch 13 8 while the blind 110 is being lowered. Since the retainer 132 is switched to its unlocked state, the total weight of the bottom part 116 and the shading structure 114 stacked on it can pull the suspension strings 126 to unwind from the rope winding units 128 respectively. , which in turn can cause the drive shaft 118 to rotate in relation to the rope drum 136. While the drive shaft 18 and the sleeve 161 turn to lower the bottom part 116, the rope drum 136 can be kept stationary and the bearing part 160 can roll and move along the radial slot 179 and the guide track 164 with respect to the first and second couplings 150 and 152 and the sleeve 161, as shown by the arrow in Figure 14. In particular, when the bottom part 116 is lowered, the spring 154 can produce resistance to friction to keep the first and second couplings 150 and 152 stationary, whereby the coupling 138 can be maintained in the uncoupled state, that is, none of the r Stop regions 177 are formed on the guide track 164. In addition, when the coupling 138 is in the uncoupled state, the radial rib 172 of the second coupling 152 is separated from the radial stop 168 which is located in a notch 165 of the first coupling 150 .
[0077] When the bottom part 116 that moves down reaches a desired height, the actuator 122 can be released. As a result, the spring 180 can resiliently recover its tightening state around the sleeve 161, which can cause the retainer 132 to change to the locking state to block the rotation of the drive shaft 118 and the sleeve 161. Accordingly , the bottom portion 116 can be locked at the desired height. While the spring 180 is recovering its clamped state, the collar 182 can also rotate in the opposite direction, which can drive the actuator 122 to rotate in an inverse way through the transmission members 184 and 186.
[0078] Figures 15 to 19 are schematic views illustrating an operation to raise the blind 110. Referring to Figure 15, when a user wishes to raise the bottom part 116, the operating rope 120 can be pulled down, which causes the operating rope 120 to unwind from the rope drum 136 and travel through the interior of the actuator 122 which is generally held stationary. As shown in Figure 16, as the rope drum 136 rotates to unwind the operating rope 120, the radial flange 136A of the rope drum 136 can push against a radial flange 150A of the first coupling 150. As a result, the first coupling 150 can rotate in relation to the second coupling 152, until the radial stop 168 of the first coupling 150 can make contact with the radial rib 172 of the second coupling 152 (as best shown in Figure 17). In this configuration, the second coupling 152 can be in a second position in relation to the first coupling 150 where stop regions 177 are formed on the guide track 164 (as best shown in Figures 18 and 19).
[0079] As the operating rope 120 is continuously pulled down, the rope drum 136 and the latch 138 can rotate synchronously until the bearing part 160 reaches a stop region 177. It should be noted that the illustrated embodiment can form two stop regions 177 on the guide track 164 in order to shorten the travel of the bearing part 16 0 to the next stop region 177. However, alternative modalities can also have the guide track 164 formed with a only stopping region 177.
[0080] When the bearing part 160 reaches a stop region 177, the coupling 138 can be changed to the coupling state. Since the bearing part 160 engages simultaneously with the stop region 177 and the radial slot 179 of the sleeve 161, the additional pull down of the operating rope 120 can drive the rope drum 136 in rotation. Due to the contact between the radial flanges 136A and 150A, the rotation of the rope drum 136 can be transmitted to the hitch 138, which in turn can transmit the rotation to the sleeve 161 and to the driving shaft 18 through the engagement of the bearing part 160 with radial slot 179 of sleeve 161 and stopping region 177 of coupling 138. As sleeve 161 rotates, the first pin 180A of spring 180 can rest against an internal surface of housing 142, which can cause the spring 180 to change from the state by squeezing the sleeve 161 to the state of loosening and to have the retainer 132 changed to a release state. Accordingly, by pulling down the operating rope 120, the latch 13 8 can be switched to the coupling state where the rotational displacement can be transmitted through the latch 138 to drive the rope drum 136, the sleeve 161 and the driving shaft 118 in synchronous rotation to raise the bottom part 116.
[0081] While the bottom part 116 is moving upwards, the user can release the operating cord 120 at any time, for example, when the bottom part 116 reaches a desired height or after the operating cord 120 has completely unwound from the rope drum 136. When the operating rope 120 is released, the spring 180 can recover its tightening state around the sleeve 161. The tightening action of the spring 180 can lock and block movement of the sleeve 161 and the drive shaft 118, in this way, the shading structure 114 can be maintained at the desired height. At the same time, the spring 140 can rotate to wind the operating rope 120.
[0082] Referring to Figure 20, as the rope drum 136 rotates in reverse, the radial flange 136A of the rope drum 136 can come into contact and push against the opposite radial flange 150A of the first coupling 150, thereby the first coupling 150 can be driven synchronously to rotate with respect to the second coupling 152.
[0083] Referring to Figures 21-23, the rotation of the first coupling 150 and the rope drum 136 can result in the movement of each radial stop 168 of the first coupling 150 away from the radial rib 172 adjacent to it, until the first coupling 150 reaches another stop position in which no stopping region 177 is formed on the guide track 164 (as shown in Figures 22 and 23). As shown in Figure 4, since extension 176 abuts a side edge 169A of slot 169 (best seen in Figure 4), guide track 164 can recover a configuration without stop regions 177, and latch 138 can be switched to the decoupling state. Thus, the spring 140 can continue to drive the rope drum 136 to rotate in reverse to wind the operating rope 120, while the first and second coupling 150 and 152 can rotate synchronously. As no stopping region 177 is formed on the guide track 164, the coupled rotation of the first and second coupling 150 and 152 can cause the bearing part 160 to slide along the guide track 164 and the radial slot 179 of the sleeve 161. As the first and second coupling 150 and 152 and the rope drum 136 rotate to wind the operating rope 120, the sleeve 161 and the drive shaft 118 can be held in a steady state due to the locking action exerted by the spring 180. Therefore, the bottom part 116 and the shading structure 114 can be kept respectively in their current position while the rope drum 136 is winding the operating rope 12 0. After the rope drum 136 has partially or completely wound the operating rope 120 (plug 192 can abut on a lower end of actuator 122 when rope drum 136 completely coils operating rope 120), the user can pull the operating rope 120 back down endend to raise the shading structure 114. The operation steps mentioned above can be repeated several times, until the shading structure 114 rises to a desirable height.
[0084] Referring to Figures 1 and 2 again, a lower portion 122A of the actuator 122 may have a thicker shape to facilitate the adhesion and manipulation of the actuator 122.
[0085] In order to avoid wrong operation that could damage internal component parts, the lower portion 122A can be provided with a safety mechanism 200 operable to selectively uncouple the lower portion 122A. When the user intends to operate the actuator 122 by holding and rotating the lower portion 122 A in the wrong direction, the safety mechanism 200 may disengage the rotation of the lower portion 122 A, so that displacement of the lower portion 122A cannot drive the unit release 134 to unlock. Figure 24 is a schematic view illustrating an embodiment of the safety mechanism 200 mounted on the lower portion 122 A.
[0086] As shown in Figure 24, actuator 122 can, for example, include a stem 122B. The safety mechanism 200 may include an outer drum 202, and an inner collar 204 mounted inside an outer drum 202. The operating rope 120 can be passed through an inner outer barrel 202 and inner collar 204 respectively. outer drum 202 can be pivotably connected to stem 122B of actuator 122 so that outer barrel 202 can rotate relative to stem 122B. The inner collar 204, in turn, can be slidably mounted with the rod 122B. Thus, while the inner collar 204 and the stem 122B of the actuator 122 can rotate synchronously, the inner collar 204 can also move lengthwise with respect to the stem 122B along a pivot Y axis of the actuator 122.
[0087] The outer drum 202 and the inner collar 204 can have contact surfaces 202A and 2 04A, respectively, which can come into contact with each other. The contact surfaces 202A and 204A can be substantially perpendicular to the pivot Y geometric axis of the actuator 122, and can, respectively, include toothed protrusions that have engagement surfaces that can engage with each other only in a predetermined direction of rotation of the inner collar 204 and outer drum 202 which correspond to the correct direction of rotation to lower the shading structure.
[0088] When the outer drum 202 rotates in an Al direction, the surfaces 202A and 204A can engage with each other (in particular, the engagement surfaces of the toothed protuberances therein) so that the rotation of the outer drum 202 can trigger inner collar 204 and actuator 122 to rotate synchronously, which corresponds to the correct direction of rotation to release the shading structure.
[0089] When the user rotates the outer drum 202 in a direction A2 opposite the direction Al, the surfaces 202A and 204A that can push against each other cannot engage with each other. As a result, the inner collar 210 can shift up and down vertically in an alternating manner while the outer barrel 202 rotates uncoupled from the inner collar 204, which corresponds to the wrong direction of rotation to release the shading structure. In this way, actuator 122 can be prevented from rotating in the wrong direction during operation, which can prevent the release mechanism 134 from being damaged due to the wrong actuation.
[0090] Figure 25 is a schematic view illustrating another embodiment of a blind 10 ', Figure 26 is an exploded view illustrating a control module 124' used on blind 110 ', Figure 27 is a schematic view that illustrates an operation to lower the blind 110 ', and Figure 28 is a schematic view illustrating an operation to raise the blind 110'. As shown in Figures 25 to 28, a difference between the blind 110'compared to the blind 110 lies in the connection between the operating rope 120 with the actuator 122 in the control module 124 '. In one embodiment, the transmission member 186 may have a hollow body.
[0091] The operating cord 120 can pass through the transmission member 186 and then attach with the actuator 122. Thus, pulling the actuator downwards 122 can synchronously drive the operating cord 120 in motion .
[0092] In addition, an upper end of the actuator 122 can be provided with a plug 194. In one embodiment, the plug 194 can be pivotably connected with an upper end of the rod 122B. Plug 194 may have a toothed portion 194A.
[0093] The transmission member 186 can have a cavity 196 (shown in Figure 28) with which the toothed portion 194A can be engaged in a separable manner. The other end portion of the transmission member 184 may be similar in construction to the previously described embodiment and engage with the transmission member 186 through gear transmission 190, which may include a helical gear, a worm gear and the like. When actuator 122 is engaged with transmission member 186 through plug 194, actuator 122 may be operable to drive transmission member 186 to rotate by engaging toothed portion 194A of plug 194 with transmission member 186. When actuator 122 is moved downwardly, plug 194 (in particular, toothed portion 194A) can disengage from transmission member 186.
[0094] Other parts of the control module 124 'and the blind 110' may be similar to the modalities previously described.
[0095] When the actuator 122 is not manipulated by a user, the spring 180 of the retainer 132 can be tightened around the sleeve 161 to block the rotation of the drive shaft 118. The shading structure 114 can thus be kept in a fixed position. Due to the action of spring 140, the rope drum 136 can pull the operating rope 120, which can cause plug 194 to insert and engage through the transmission member 186.
[0096] In conjunction with Figures 25 and 26, Figure 27 is a schematic view illustrating an operation to lower the blind 110 '. As shown in Figure 27, when the bottom part 116 must be lowered, the actuator 122 can be rotated gently. Due to the transmission of movement through the toothed portion 194A and the transmission members 184 and 186, collar 182 can be driven to rotate at an angle and move the second pin 180B of spring 180 to loosen spring 180. Retainer 132 can, thus, switch to the release state. The bottom part 116 can then lower by gravity as described until it reaches a desired height. Once the bottom part 116 reaches the desired height, the actuator 122 can be released, and the spring 180 can recover its clamped state to keep the bottom part 116 in the desired position.
[0097] As shown in Figure 28, when the bottom part 116 must be lifted, the actuator 122 can be pulled downwards, in this way, the plug 194 can disengage from the cavity 196 of the transmission member 186 and the operating rope 120 can unwind from the rope drum 136. As previously described, the rope drum 136 can rotate in the direction to unwind the operating rope 120, that rotational displacement of the rope drum 136 being transmitted through the latch 138 to the sleeve 161 and the drive shaft 118. In turn, the rotation of the sleeve 161 can cause the first pin 180A of the spring 180 to touch an internal surface of the housing 142, which results in the change of the spring 18 0 of the tightening state in the sleeve 161 for the loose state. The retainer 132 can thus change to the release state. Thus, by pulling down the actuator 122, the rope drum 136 and the drive shaft 118 can be driven to rotate synchronously to raise the bottom part 116.
[0098] While bottom part 116 is lifting, actuator 122 can be released at any time. When actuator 122 is released, spring 180 can recover its tightening state in sleeve 161 to lock and block rotation of sleeve 161 and drive shaft 118. Shading structure 114 can thus be maintained at the desired height . When actuator 122 is released, spring 140 can also trigger reverse rotation of rope drum 136 to wind operating rope 120. While rope drum 136 is winding operating rope 120, actuator 122 can move concurrently upwards until plug 194 inserts through cavity 196 to engage with transmission member 186.
[0099] Figures 29 to 33 are schematic views that illustrate another modality of a control module 324. As shown in Figure 29, a difference of control module 324 from the previous modalities is located in the construction of the coupling 338. In this modality, hitch 338 can include a movable coupling 350 which is mounted with fixed rod 146. Coupling 350 can rotate with respect to fixed rod 146, and can move lengthwise along the geometric axis of fixed rod 146.
[00100] Figure 30 is a schematic projection view of an external portion of coupling 350. An external surface of coupling 350 can be formed with one or more guide tracks 364 (three guide tracks 364 are shown in an exemplary manner in Figure 30) . In addition, a side of the coupling 350 facing the sleeve 161 can be formed with a toothed surface 355.
[00101] Referring to Figures 29 and 30, the rope drum 136 connected with the operating rope 120 can have a circular inner cavity 337 with an inner side wall formed with one or more protrusions 339. Coupling 350 can be mounted through the internal cavity 337 so that each protrusion 33 9 can be received and guided in a mobile way through an associated guide track 364. The interaction between protuberance 339 and guide track 364 can change operably, a rotational displacement of the drum of rope 336 in concurrent rotation and displacement along the length of the coupling 350 in relation to the rope drum 336, which can trigger the coupling 350 to move towards or away from the sleeve 361. Furthermore, the sleeve 361 affixed with the drive shaft 118 may have a side facing coupling 350 formed with a toothed surface 362. During operation, the toothed surface 362 of the sleeve 361 can engage with the toothed surface 355 of the 350 coupling.
[00102] Regarding the retainer, the release unit and other parts, the same constructions, as previously described, can be applied.
[00103] Figures 31 and 32 are schematic views that illustrate an operation of the control module 324 to raise the shading structure. When the operating rope 120 is pulled downward, the rope drum 336 can rotate, which can drive the coupling 350 to rotate concurrently and move towards sleeve 3 61 through the interaction of protrusion 339 and the guide track 364 until the toothed surfaces 3 62 and 355 engage with each other. Once the coupling 350 engages with the sleeve 361, continuous rotation of the rope drum 336 can drive the sleeve 361 and the driving shaft 118 to rotate to lift the bottom part 116 (as shown in Figure 1).
[00104] Figures 33 and 34 are schematic views that illustrate an operation of the control module 324 to wind the operating rope 120. While it acts to wind the operating rope 12 0, the spring 14 0 can drive the drum rope 33 6 to rotate in reverse, which in turn can trigger coupling 350 to move away from sleeve 361 through the interaction between protrusion 339 and guide track 364. As a result, the toothed surface 362 of the sleeve 361 can disengage from the toothed surface 355 of the coupling 350. Thus, the rotation of the rope drum 336 can be decoupled, so that sleeve 3 61 and drive shaft 118 can be locked and held stationary by spring 180 of the retainer while the drum 336 is winding the operating rope 120.
[00105] It is worth noting that the safety mechanism 200 previously described with reference to Figure 24 can be suitable for use in combination with any control modules. In the embodiment shown in Figures 25 to 33, the same safety mechanism 200 can therefore be mounted with the lower portion 122A of the actuator 122 to prevent the actuator 122 from rotating in the wrong direction to drive the release unit.
[00106] With the structures and operating methods described in this document, the retainer of the control module can be changed from the locking state to the release state by turning an actuator, thus, the shading structure can be lowered through the action of the gravity. The blinds described in this document can therefore be convenient to operate.
[00107] Examples of structures and methods have been described only in the context of particular modalities. These modalities are intended to be illustrative and not limiting. Many variations, modifications, additions and improvements are possible. Thus, plural examples can be provided for the components described in this document as a single example. The structures and features presented as separate components in the example configurations can be implemented as a combined structure or component. These and other variations, modifications, additions and improvements may be within the scope of the following claims.
