专利摘要:
The present disclosure relates to a very streamlined, low profile, tilt-in style vehicle article carrier system for use on a wide variety of cars and trucks. The system uses a pair of side rails (14a, 14b) to support a pair of crossbars (22 and 23) in storage positions thereon where the crossbars (22 and 23) are attached parallel to the side rails ( 14a, 14b) or in service positions where the transverse bars (22 and 23) are fixed perpendicularly between the side rails (14a, 14b). The side rails (14a, 14b) each incorporate a rotatable end support subsystem (26) that automatically elevates an end of its associated crossbar when the crossbar is pivotally moved to its operating position. This allows the crossbars to form a very low profile in their storage positions.

ARTICLES SUPPORT FOR LOW PROFILE VEHICLES WITH ROCKER CROSS BARS IN PLACE
The present application claims the benefit of Provisional U.S. Patent Application No. 62 / 332,267, filed May 5, 2016. All of the above disclosure of the application is incorporated herein by reference.
The present disclosure relates to article support systems for use with motor vehicles, and more particularly to a low profile vehicle article carrier system with crossbars pivoted in place that can be easily stored on side rails. respective, and when necessary, they can be tilted in place extending perpendicularly between the side rails.
The statements in this section simply provide background information relating to this disclosure and may not be prior art.
Vehicle support systems are becoming increasingly popular, particularly because of the smaller size of passenger cars. The vehicle article carriers easily transport a wide variety of items over an outer body surface, such as the roof of a vehicle, and significantly increase the space available to passengers in the passenger compartment of the vehicle.
The fact that the vehicle article support system does not affect the aerodynamics of the vehicle has also become more important in recent years. As a result, interest in vehicle article support systems using retractable crossbars has increased significantly. The vehicle article carriers with retractable crossbars allow crossbars to be arranged along respective side rail members, when they are not needed, and put in place when necessary. This allows the vehicle article carrier to be configured to minimize any adverse effect on the aerodynamics of the vehicle when the vehicle article carrier is not needed, while permitting the crossbars of the vehicle system. be configured in a service orientation (that is, perpendicularly between the side rails) when the system is needed.
The applicant of the present disclosure is a leader in the development of vehicle article support systems with retractable crossbars. In particular, the applicant of the present disclosure has developed a number of high-performance vehicle article support systems with "swing-in-place" cross bars. These systems have crossbars that can be pivoted from one end so that they can be positioned to extend perpendicularly between a pair of fixedly mounted side rails. However, with a system tilted in place, the crossbars do not need to be completely physically detached from the side rails when they are repositioned from a storage configuration to a service configuration.
Given the high level of interest in vehicle article support systems that use tilted crossbars in place, there is a keen interest in the continued development and improvement of the features and operation of such systems. There is particular keen interest in the provision of an aesthetically pleasing, low-profile aerodynamic vehicle support system with transverse bars tilted in place.

The following disclosure is merely an example and is not intended to limit the present disclosures, applications or uses. It will be understood that in the drawings corresponding indicia indicate similar or corresponding parts and features.
Referring to Fig. 1, there can be seen an article support system 10 according to an embodiment of the present disclosure. The system 10 is installed on a vehicle 12. The vehicle 12 can be virtually any form of vehicle such as, but not limited to, a sedan, SUV, minivan or large van. The system 10 can also be used on pickups, either on a roof of a cab of a pickup or on the tray of a pickup. If used on the tray, the system 10 would be supported by the upper edges of the tray sidewalls to provide a means for supporting articles above a tray floor.
The system 10 includes a pair of elongate side rails 14a and 14b which are fixedly mounted to the outer body surface 12a, in this case a roof, of the vehicle 12 by suitable fasteners well known in the sector. The lateral rails 14a and 14b each comprise a very aerodynamic front portion 16, recessed portions 18 and a rear portion 20. The recessed portion 18 of each lateral rail 14a and 14b is of sufficient length to accommodate an associated transverse bar 22 or 23 in this one when the crossbar is in a storage configuration. FIG. 1 shows the transverse bars 22 and 23 arranged in their respective recessed portions 18 while FIG. 2 shows the transverse bars 22 and 23 in their service orientations extending perpendicularly between the lateral rails 14. The system 10 thus forms a a "swing-in" vehicle article carrier system, wherein the crossbars 22 and 23 can be stored on their respective side rails 14 when they are not needed, and rotated rapidly and easily in their service configurations when they are needed. This allows the system 10 to present an extremely aerodynamically efficient and visually pleasing profile when the transverse bars 22 and 23 are stowed.
Referring to FIG. 3, the construction of the cross bar 22 can be seen in more detail with its various elements required to secure it for tilting movement in place between the side rails 14. The crossbars 22 and 23 in this example are of identical construction, so only the crossbar 22 will be described in detail. The cross bar 22 includes a tubular central section 24, a rotatable end support subsystem 26 at the first end 22a, and a detent end support sub-system 28 at a second end 22b. The lateral rail 14a comprises a single mounting recess 30 in its front portion 16, while the lateral rail 14b comprises an identical mounting recess 32 in its rear portion 20. The first end 22a of the transverse bar 22 is fixed in rotation and in elevation to its associated mounting recess 30, and movable around the mounting recess 30 between its storage and service positions. A first end 23a of the cross bar 23 is rotatably and elevately attached to its associated mounting recess 32 by its rotatable end support subsystem 26, and likewise is movable around the mounting recess. 32 between its storage and service positions. The side rail 14a also includes a front snap recess 34 and a rear snap recess 36, both of which are positioned in its rear portion 20. Conversely, the side rail 14b includes a front snap recess 38 and a snap recess rear snap 40, both placed in its front portion 16.
In its operating position, the second end 22b of the crossbar 22 is fixed to the front snap recess 38 of the side rail 14b. In its storage position, the second end 22b of the crossbar 22 is fixed to the front snap recess 34 of the side rail 14a and is substantially supported in the recess portions 18 of the side rail 14a. This allows the side rail 14a and the crossbar 22 to form a low profile and a highly efficient profile from the aerodynamic point of view and aesthetically pleasing. In its operating position, the second end 23b of the transverse bar 23 is coupled to the rear latching recess 36 of the side rail 14a by its latching end support sub-system 28, and in its position of storage it is coupled to the rear snap recess 40 in the side rail 14b.
Referring to Figure 4, the construction of the rotatable end support subsystem 26 can be seen in more detail. The rotatable end support subsystem 26 includes an end support 42 having a neck portion 44 which fits into the tubular central section 24 of the cross bar 22. The end support 42 has a groove 46 which receives an end of a cable 48. The cable 48 comprises a pair of fixedly attached tabs 50 between which the opposite ends of a coil spring 52 are fixed. The coil spring 52 helps swallow the slack in the cable 48 when the cross bar 22 is fully assembled.
Referring to Figures 4, 5 and 6, the end support 42 further includes a rounded end portion 54 having a pair of spaced arms 56 projecting therefrom which form a slot 58 therebetween. The slot 58 receives a neck portion 62 of a user-engageable actuating member, which in this example is an actuating lever 60 pivotally mounted, user-friendly. The neck portion 62 also has a bore 64 which receives a pin 66. This allows the actuating lever 60 to pivot about the end support 42 between closed and open positions.
Referring to Figures 5 and 6, one end of the cable 48 includes a tab 68 which is captured in a recess 70 in the neck portion 62 of the actuating lever 60. This allows the actuating lever 60 to pull on the cable 48 when the operating lever 60 is pulled upwards in its open position as shown in FIG. 5. The end support 42 further comprises a recess 72 (FIG. 6) in which a guide wheel 74 is inserted . The guide wheel 74 is mounted in the recess 72 (FIG. 6) for rotational movement about a pin 76. Once the cable 48 is assembled on the end support 42, the voltage supplied on the cable to the opposite end of the cross bar 22 (will be discussed in the following paragraphs) ensures that the guide wheel 74 and its pin 76 do not move out of their position in the recess 72.
Referring further to FIG. 4, the rotatable end support subsystem 26 further comprises an upper mounting body 78 having a U-shaped upper portion 80 and a recessed lower portion 82. The upper portion of U-shape 80 receives the rounded end portion 54 of the end support 42. The spindle 66 can be placed through bores 84 in the U-shaped upper portion 80 and through the bore 59 in the d-portion. rounded end 54 for securing the rounded end portion for pivotal movement within the U-shaped upper portion 80, and about a first axis. The upper mounting body 78 also includes a bore 86 into which a threaded bolt 88 can be inserted. The threaded bolt 88 also extends through a bore 90 into a lower mounting member 92. A nut 94 may be used to secure the lower mounting member 92 to the upper mounting body 78.
Figure 4 also shows that the lower mounting member 92 includes a plurality of outwardly projecting cylindrical arms 96 spaced approximately 90 degrees apart. The lower mounting member 92 is captured in the recessed lower portion 82 with the outwardly projecting arms 96 of cut-out sections 97 in the lower mounting member 92. Once the lower mounting member 92 is assembled on the upper mounting body 78, it is fixedly attached relative to the upper mounting body 78. As a result, when the cross bar 22 is rotated, the arms 96 also rotate, allowing the crossbar 22 to pivot about it. a second axis that is orthogonal to the aforementioned first axis.
Referring to Figures 7 and 8, it can be seen that the mounting recess 30 includes a plurality of helical grooves 98. In this example four helical grooves 98 are provided, one for receiving at the end portion of the Each of the helical grooves 98 also includes a flat section 100. The helical grooves 98 serve to elevate the first end 22a of the crossbar 22 when the transverse bar 22 is turned from its storage position to its outermost position. service position. The flat sections 100 are further constructed so that the transverse cylindrical arms 96 reach and roll on the flat sections 100 just before the cross bar 22 reaches the front snap recess 38 when turned into the position. on duty. The flat sections 100 provide a solid support surface, as well as providing a small degree of rotational movement which helps the user to align the second end 22b of the cross bar 22 with the front snap recess 38. Option, but preferably, the front portion 16 of the side rail 14a may be provided with a cut or scalloped section 102 which allows the user to more easily grasp the actuating lever 60 with a finger or thumb when the lever The actuation is in its closed position, and thus assists the user in initially lifting the operating lever into its open position. The lower mounting member 92 may be assembled in the mounting recess 30 from a lower end 104 of the mounting recess, as shown in Figure 6. Once the lower mounting member 92 is placed in the mounting recess 30, it can be rotated so that the arms 96 engage in the helical grooves 98. When the lower mounting member 92 has been advanced to near an upper end 106 of In the mounting recess 30, the upper mounting body 78 can be attached to the lower mounting member 92 via the threaded bolt 88 and the threaded nut 94. The actuating lever 60 can then be assembled onto the body of the assembly. upper mounting 78.
This rotary end support subsystem 26 is an important feature of the system 10 because of the strong desire to make the system 10 a low profile and aerodynamic when the transverse bars 22 and 23 are in their storage positions. The rotatable end support subsystem 26 allows the cross bar 22 to adopt a very low profile when in its storage position, and further allows the first end 22a of the crossbar 22 to move. be moved upwards during the rotation of the crossbar into its operating position. The elevated position of the cross bar 22 when placed in its service position also provides an additional degree of clearance between the cross bar 22 and the outer body surface 12a of the vehicle 12, which may be useful when attaching clamps associated with bike carriers, ski racks, luggage chests, etc. at the crossbar 22.
Referring to FIGS. 9a-9f and 14, the various elements of the latching end support sub-system 28 of the cross bar 22 can be seen in more detail. Referring specifically to FIG. 9a, the snap-on end support sub-system 28 includes a cover 108, a pair of snap arms 110 and 112, a cam member 114, a torsion spring 116, a coil spring 118, and a main body portion 120. The main body portion 120 includes a neck portion 122 that fits into the tubular central portion 24 of the cross bar 22, and also includes a groove 124 for receiving one end of the cable 48.
The torsion spring 116 is placed on a boss 126 which has a tapping 128. The cam member 114 is placed on the boss 126, a tenon 116a of the torsion spring 116 engages in a hole 115 in a rear face of the cam member as shown in Figure 9b. The other post 116b of the torsion spring 116 engages a hole 117 (Fig. 9c) in the main body 120 so that the torsion spring is able to exert a rotational biasing force on the cam member. 114 which serves to urge the latching arms 110 and 112 in outward latching positions, which will be further explained in the following paragraphs. A threaded bolt 129 is placed through a hole 108a in the cover 108, through a hole 114a in the cam member 114 and threadably engages the tapping 128 in the boss 126 to secure the cam member to the rotational movement around the boss.
Referring further to FIGS. 9a, 9d, 11 and 12, the latching arms 110 and 112 each comprise bores 110a and 112a through which pins 130 and 132 are inserted to allow pivoting movement of the arms snap. The pins 130 and 132 are housed in channels 130a and 132a in the main body 120 as shown in Figure 9d. The snap arm 110 includes a portion of a pin 110b projecting therefrom which is coupled to an upper end of the spring 118. The pin 110b is placed in a well 119 shown in Fig. 9d when the subsystem snap-on end support 28 is fully assembled. The lower end of the spring 118 is coupled to a pin 134. The pin 134 is inserted into a slot (not shown) in the main body portion 120. The spring 118 thus serves to bias the latching arms 110 and 112 to the outside of each other, which effectively allows the latching arms to adopt a normally latched orientation unless the user moves the actuating lever 60 into the open position. This will be further described in the following paragraphs.
Referring to Figures 9f and 9d, once fully assembled, the cover 108 may be attached to the main body 120 using the threaded bolt 129. In Figure 9f, it can be seen that a lower face of the cover 108 includes tabs protruding 108b, 108c and 108d. The tab 108b projects partially into the recess 119, and the tabs 108c and 108d cover the areas 133 adjacent to the pins 130 and 132.
The snap arm 112 further includes an ear portion 112b with a portion of a pin 112c projecting therefrom. Pin 112c is supported within a slot 113 (Fig. 9e) in a rear face of latching arm 110 when latching arms 110 and 112 are assembled together. Snap arms 110 and 112 are shown assembled together in Figures 9d and 10-12. Another pin 136 (shown in FIG. 9) is placed in a hole 121 in a rear face of the ear portion 112b of the snap arm 112, as shown in FIGS. 9d and 9e. Pin 136 is placed so that it rolls on a cam surface 114b of cam member 114. This is shown in Figures 13 and 14. When cam member 114 is rotated in a first direction of rotation the cam surface 114b lifts the pin 136, which simultaneously causes a pivotal movement of the latching arms 110 and 112 towards each other in retracted positions against the biasing force provided by the coil spring 118. The snap arms 110 and 112 are shown in their fully retracted positions in Fig. 12. The rotation of the cam member 114 in the opposite direction (i.e., second direction of rotation) allows the coil spring 118 to pull the pin 136 downward, which causes the snap arms 110 and 112 to rotate in their deployed positions as shown in Fig. 11. Fig. 13 shows the pin 136 at an extreme end me of the cam surface 114b. In this position, snap arms 110 and 112 will be in their outwardly extending positions (as shown in FIG. 11).
Referring further to FIGS. 9 and 11, one end of the cable 48 is placed in the groove 124 and partially wound around the cam member 114. A tab 142 at the end of the cable 48 engages a recess 114c in the cam member 114. The lifting of the actuating lever 60 thus serves to pull the end of the cable 48 having the tab 142 against the biasing force provided by the coil spring 118 and the torsion spring 116. This causes the cam member 114 to rotate in the first direction of rotation, which raises the pin 136, which causes the pivoting movement of the latching arms 110 and 112 in their retracted positions. When the operating lever 60 is released, the coil spring 118 pulls the spring 136 downward, causing the cam member 114 to rotate in the opposite rotational direction with the aid of the biasing force. provided by the torsion spring 116, and thereby causes the detent arms 110 and 112 to move in their deployed positions (Fig. 11).
Referring to Figures 15 and 16, the construction of the rear snap recess 36 of the side rail 14a can be seen in more detail. Figure 15 shows the detent recess 36 having a movable cover 144. The cover 144 is biased into a position generally aligned with a support surface 146 associated with the detent recess 36 by a coil spring 148 when the second 22b end of the crossbar 22 is not attached. The coil spring 148 is supported on the U-shaped frame member 150, as shown in Fig. 16. The cover 144 is prevented from being pushed out beyond the support surface 146 by a plurality of stop elements 152 (Figure 16). The cover 144 is engaged with an inner surface 153 of the side rail 14a, which limits its upward movement. The arm portions 150a and 150b of the U-shaped frame member 150 allow the cover 144 to slide up and down. The stop elements 152 have been omitted in FIG. 15 for the sake of clarity.
Figures 17 and 18 show the latching end support subsystem 28 in its latched and unshrinked position, respectively, with respect to the latching recess 38. In FIG. 17, it can be seen that in FIG. In the latching position, the jaws 138 and 140 engage flange portions 154 and 156, respectively. The cover 144 is pushed down which compresses the spring 148. The upward biasing force provided by the spring 148 serves to reduce the possibility of any slamming of the second end 22b of the crossbar 22 when in its service or storage positions. When the cover 144 is in its raised position (FIG. 15), it closes the snap recess 38 and helps to form an aesthetically pleasing and aerodynamically efficient surface. When the latching end support system 28 is pushed into its detent position, as shown in FIG. 18, the jaws 138 and 140 are free to disengage the flange portions 154 and 156, respectively. In this orientation, the second end 22b is free to be raised and moved away from the detent recess 38.
To move the crossbar 22 from its storage position to its operating position, the user simply lifts the actuating lever 60. This retracts the snap arms 110 and 112 and releases the end support subsystem at the second end 22b of the transverse bar 22. The spring 148 in the detent recess 36 then pushes the second end 22b of the cross bar 22 upwards as the cover 144 is lifted. This frees the second end 22b of the side rail 14a. The user can then release the operating lever 60 and use his other hand to help turn the cross bar 22 into its operating position extending perpendicularly to the side rail 14a. As the user turns the cross bar 22, the rotatable end support subsystem 26 at the first end 22a of the side rail 14a lifts the first end 22a upwardly. When the user has aligned the second end 22b with the detent recess 38 in the side rail 14b, the user lowers the second end so that the detent arms 110 and 112 enter the detent recess 38. The weight of the cross bar 22 helps to accommodate the second end 22b in the snap recess 38, thus requiring little or no additional effort on the part of the user. When the latching arms 110 and 112 enter the latching recess 38, they are compressed toward each other in the retracted position, prior to engagement with the outside when the jaws 138 and 140 clear the latches. Flanges 154 and 156. The order of the above operations is reversed when the cross bar 22 needs to be replaced from its operating position to its storage position. The operations of moving the cross bar 23 from the storage position to the service position, or vice versa, are identical to those described for the transverse bar 22. The operation of moving each transverse bar 22 and 23 between its positions of Storage and service only takes a few seconds and can be performed without requiring significant force, and without the need for external tools. Thus, even a single person with limited strength and stature can easily handle the crossbars 22 and 23 between their storage and service positions.
It will be appreciated that while only the operation and construction of the crossbar 22 have been described, the construction and operation of the cross bar 23 are identical. In the same way, the construction of the mounting recess 32 is identical to the mounting recess 30, and the construction of the front detent recess 38 is identical to the rear detent recess 36.
Referring to Figs. 19-21, a latching end support sub-system 28 'is disclosed in accordance with another embodiment of the present disclosure. The latching end support subsystem 28 'is similar to the subsystem 28 except that one of the detent arms 110' and 112 ', in this example the detent arm 110 ', comprises a user-friendly portion forming an actuating member 11Γ, which functions as the element equivalent to the actuating member 60 of the latching end support subsystem 28. L actuating member 111 'can be grasped using one or more fingers and lifted along the arrow 113' in FIG. 20 to allow the snap-on end support sub-system 28 'to be unclipped directly from the second end 22b of the cross bar 22, rather than indirectly from the first end 22a of the crossbar 22. The latching end support sub-system 28 'can be used at the second end. 22b and 23b cross bars 22 and 23, or perhaps just one of the cross bars 22 or 23.
The latching end support sub-system 28 'is similar to the subsystem 28 in that it depends on a biasing element, in this embodiment a coil spring 118' hooked on a pin 110b ', which urges the snap arms 110' and 112 'in normally outwardly extending orientations (i.e., a normally snapped orientation). The pins 130 'and 132' are housed in channels 130a 'and 132a' in a main body 120 ', and extend through bores 110a' and 112a 'in the latching arms 110' and 112 ', respectively to allow the pivotal movement of the detent arms. The latching arms 110 'and 112' are further coupled by a spindle and a bore (not shown in Fig. 19) which are identical to the spindle 112c and the bore 113 in Fig. 9e. The coil spring 118 'is attached at one end to a pin 134' (Fig. 19) and at its opposite end to the pin 110b '.
It will be appreciated that with the latching end support sub-system 28 ', the actuating lever 20, the cable 48, the cam member 114, the pin 136 and the guide wheel 74 will not be affected. required. The control of the snap and unclamping of the crossbar 22 will be performed by the user only at the second end 22b of the crossbar 22, and the second end 23b of the crossbar 23. It will therefore be appreciated that the sub -Ratching end support system 28 'allows the removal of a number of elements that would be used otherwise with the subsystem 28 and the crossbar 22 or 23, and thus a reduction in the overall cost of the system 10.
While various embodiments have been described, one skilled in the art will recognize that modifications or variations could be made without departing from the present disclosure. The examples illustrate the various embodiments and are not intended to limit the present disclosure. Therefore, the description and the claims must be interpreted generously, only with such limitation when necessary in view of the relevant prior art.
Of course, the invention is not limited to the embodiments described above and shown, from which we can provide other modes and other embodiments, without departing from the scope of the invention. .
