Abstract
A vehicle article carrier having a pair of side rails and at least one adjustable cross bar. The adjustable cross bar includes a pair of bracket members at its outermost ends which are adjustably positionable along the side rails. Each bracket member includes a rotator having a circumferential camming surface which is in contact with a head portion of a locking member. When the rotator is rotated in a first direction, the camming surface urges the locking member out of clamping engagement with its associated side rail. When the rotator is urged rotationally in the opposite direction, a biasing member is allowed to urge the locking member into clamping engagement with the associated side rail. In a preferred embodiment, the locking member includes a pair of raised surfaces which cooperate with notches formed in overhanging ledge portions of a channel of the associated side rail to allow the locking member to be positively engaged with the side rail when the rotator is in the locked position. The rotator has the desirable feature of remaining substantially flush with the outer surface of its associated bracket member regardless if it is in its locked or unlocked positions.
Description
21 q2301 VEHICLE ARTICLE C~R~T~
BACKGROUND OF THE INVENTION
1. Technical Field This invention relates to vehicle article carriers, and more particularly to an adjustable vehicle article carrier for adjustably supporting articles above an outer body surface of a vehicle such as a roof or deck lid of a vehicle.
BACKGROUND OF THE INVENTION
1. Technical Field This invention relates to vehicle article carriers, and more particularly to an adjustable vehicle article carrier for adjustably supporting articles above an outer body surface of a vehicle such as a roof or deck lid of a vehicle.
2. Discussion Vehicle article carriers are used in a wide-variety of applications to support a variety of articles above an outer body surface of a vehicle such as a roof or deck lid of the vehicle.
Some vehicle article carriers are adjustable via one or more cross bars which may be adjustably positioned along a pair of raised side rails fixedly secured to an outer body surface of the vehicle. Such vehicle article carriers are shown in, for example, U.S. Patent Nos. 4,684,048, 4,982,886 and 5,082,158, all assigned to the assignee of the present application.
The vehicle article carriers in use at the present time and those embodied in the above-mentioned U.S. patents have proven to be very useful for the purpose of transporting articles which are either too large or awkward to be transported within the interior of a vehicle. Nevertheless, there still remains a need for a vehicle article carrier having a means for adjusting 2 J 92 ~C/
the position of at least one cross bar of the carri~r in ~ ~anner which is extremely simple in construction and requires only a minimum number of parts to accomplish locking of an adjustable cross bar at a desired location along a pair of side rails.
SUMMARY OF THE INVENTION
The above and other objects are provided by a vehicle article carrier in accordance with preferred embodiments of the present invention. In one preferred embodiment, the vehicle article carrier of the present invention includes a pair of outer side rails each having a channel formed therein, with each of the outer side rails being fixedly secured to an outer body surface of a vehicle and positioned generally parallel to one another.
A cross bar is provided which has at its outermost ends a pair of bracket members fixedly secured thereto. The bracket members releasably engage with the outer side rails to allow the cross bar to be quickly locked in position on the side rails such that the cross bar is not moveable longitudinally along the outer side rails. The bracket members each also include a manually actuatable control which releases each bracket member from its outer side rails to allow the cross bar to be easily, slidably positioned along the outer side rails at a desired position in order to support articles of varying dimensions thereon.
2 1 ~230 1 In one preferred embodiment, each bracket member includes a recess formed in an outer surface thereof and an opening formed in a base portion. A neck portion of a locking member extends through the opening in the base portion into the recess. The locking member includes a base plate which is of dimensions enabling it to reside within the channel of an associated outer side rail and to move slidably within the channel when the bracket member is in an unlocked position and moved along the outer side rail. A rotator is positioned partially within the recess and rotatably mounted within the recess. The rotator includes a circumferential camming surface which is positioned to abuttingly engage a head portion of the locking member. A biasing member is also positioned within the bracket member and is operably coupled to the neck portion to cause the locking member to be urged into abutting (i.e., clamping) engagement with the channel of the associated side rail when the rotator is in a "locked" position. When the rotator is rotated into an "unlocked" position, the camming surface urges the neck portion outwardly of the bracket member such that the base plate becomes disengaged (i.e., unclamped~ within the channel, thereby allowing the bracket member to be slidably, adjustably positioned along the side rail while the rotator is held in the unlocked position. The rotator is constructed such that it may be engaged with two or more fingers of a hand of the user and easily rotated with a minimal degree of effort. The biasing member causes the locking member to be urged into locking engagement within the channel of the side rail once the rotator is released.
- In the preferred embodiment, the channel of each outer side rail includes a pair of overhanging ledge portions which each have a plurality or holes formed therein in spaced-apart fashion. The base plate of the locking member also includes a pair of raised portions which are positioned to engage within a corresponding pair of the notches in the overhanging ledge portions when aligned with the corresponding pair of notches, and when the locking member is urged into the locked position by appropriate rotation of the rotator.
In the preferred embodiment, the rotator includes a pair of depressions formed on opposite sides of a central member and is positioned within the recess such that it is substantially flush with an outer surface of the bracket member. The depressions allow the fingers of a hand to easily grasp the central member to rotate the rotator.
The preferred embodiments thus include a minimum number of moving parts to accomplish locking and unlocking of the bracket member at desired locations along the length of an associated side rail. The clamping engagement provided by the locking member of each bracket member and the engagement of the raised surfaces with a corresponding pair of the notches in the channel member serve to provide extremely secure clamping of the cross bar at a large plurality of desired locations along the side rails.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Figure 1, there is shown a vehicle 12 having an outer body surface 14 upon which a vehicle article carrier 10 in accordance with the present invention is mounted.
The vehicle article carrier 10 comprises a pair of outer side rails 16 fixedly secured to the outer body surface 14 and positioned generally parallel to one another. The outer side rails 16 are also positioned so as to extend along a major length of the outer body surface 14. Optionally, a plurality of intermediate slats 17 could be provided and secured to the outer body surface 14. A fixed across bar 18 is provided as is an adjustable cross bar 20. It will be appreciated, however, that two adjustable cross bars 20 could just as readily be provided, but that in most applications it is anticipated that only one of the two cross bars will need to be adjustable. The adjustable cross bar 20 has outermost end portions 22 to which are fixedly secured a pair of bracket members 24. The bracket members 24 are adjustably positionable along the length of each of their respective outer side rails 16 to enable the cross bar 20 to be positioned relative to the cross bar 18 as needed to support variously sized articles thereon.
- Referring to Figures 2 and 3, one of the bracket members 24 is shown in greater detail. With specific reference to Figure 3, each bracket member 24 includes a housing 26 having an outer surface 28 and an inner surface 30. The outer surface 28 includes a hollowed out portion or recess 32 formed in part by a generally circular opening 34. A rotator 36 is positioned in the recess 32 and is of a generally circular configuration having a diameter just slightly smaller than the circular opening 34 so as to fit within the circular opening 34 when assembled to the housing 26.
With further reference to Figure 3, the inner surface 30 of the housing includes an integrally formed mounting post 38 which extends generally perpendicularly from the inner surface 30. The mounting post 38 includes a centrally disposed opening in the form of a bore 40. Both the mounting post 38 and the bore 40 are disposed so as to be at the approximate geometric center of the circular opening 34. The housing 26 further includes a base portion 42 having an opening in the form of a bore 44 extending therethrough. A plurality of foot portions 46 (visible in Figure 2) are also integrally formed with the base portion 42.
The cross bar 20 (Figure 1) is fixedly secured to the housing 26 via one or more threaded screws (not shown) in conventional fashion such that the cross bar 20 and the bracket members 24 form a rigid, sturdy and unitary member.
21. q2301 With further reference to Figure 2, the rotator 36 includes an outer surface 48 having a pair of depressions or recesses 50 formed on opposite sides of a central member 52.
Thus, the rotator 36 can be easily rotated manually by a user by gripping the central member 52 with two or more fingers of a hand and turning the rotator 36 either clockwise or counterclockwise.
Referring again to Figure 3, the bracket member 24 can be seen in the locked position. The rotator 36 is secured to the mounting post 38 by a threaded screw 54 or other similar fastening member which extends through the bore 40 and threadably engages within an opening 56 in the rotator 36. The rotator 36 also includes a centrally disposed boss portion 58 having an opening 60 which receives the mounting post 38. In this manner, the rotator 36 is free to rotate about the mounting post 38 while being secured thereto. It will be appreciated that any form of attachment of the rotator 36 to the mounting post could be used provided it allows for easy rotation of the rotator 36.
With further reference to Figures 3 and 8-10, the construction of the rotator 36 can be seen in even greater detail. The rotator 36 includes a camming surface 62 extending circumferentially around a portion of the opening 60. The camming surface 62 includes a flat portion 62a (visible in sections 8 and 10), the function of which will be described momentarily. With specific reference to Figures 9 and 10, the slope of the camming surface 62 is clearly apparent. It will be appreciated also that while the camming surface 62 is shown as extending approximately 180 around the opening 60, that the camming surface 62 could be of a greater or lesser arc of travel.
21 923Cl ~'or example, the camming surface 62 could be formed to extend over a 90 arc of travel, which would obviously require a more pronounced (i.e., steeper) slope. It is anticipated that the 180 arc of travel of the camming surface, as indicated in Figure 8, will be most desired to provide a convenient and comfortable locking and unlocking action of the rotator 36.
With further reference to Figure 3, the bracket member 24 can be seen to include a locking member 64 which extends through the bore 44. With brief reference to Figure 5, the locking member 64 includes a base plate 66, a neck portion 68 and a head portion 70. The neck portion 68 includes a pair of notches 72 which form an intermediate length 73. The base plate 66 includes a pair of raised surfaces 74 positioned directly across from one another. The neck portion 68 and head portion 70 are integrally formed with the base plate 66 by being stamped or cut-out of the base plate 66 and then bent so as to extend generally perpendicularly from the base plate 66. Similarly, the raised surfaces 74 are formed by being stamped from the base plate 66. It will be appreciated, however, that the neck portion 68 and the raised surfaces 74 could be formed from independent components if desired. It will be appreciated then that the locking member 64 could take a variety of different designs provided some form of base plate and some form of neck portion are included.
With further reference to Figure 3, each outer side rail 16 includes an outer wall 76, an inner wall 78 and a pair of overhanging ledge portions 80 which help to form a channel 82.
The outer side rails are each supported on an optional mounting pad 84 and secured to the outer body surface 14 of the vehicle 12 (Figure 1) via threaded screws in the conventional manner.
Each outer side rail 16 is preferably roll-formed from a single piece of suitably strong material such as steel, but it could also be formed from multiple sections of material secured together with suitable fastening elements.
With further reference to Figures 3 and 7, it can be seen that the overhanging ledge portions 80 each include a plurality of spaced-apart notches 86. The notches 86 are adapted to engage with the raised surfaces 74 of the locking member 64 when the locking member 64 is urged into the locked position, as shown in Figure 3. This feature of the present invention will be described more fully in the following paragraphs. It will also be appreciated that the notches 86 could alternatively be formed so as to extend completely through the overhanging ledge portions 80 if desired. It will also be appreciated that conventional side rails without notches could also be employed and still provide excellent securing of the cross bar 20 at a desired location along the side rails 16.
With further reference to Figures 3 and 6, the bracket member 24 also includes a biasing member 88. The biasing member 88, as shown in Figure 6, is formed from a length of spring steel having a T-shaped cut-out 90 and a lip portion 92 resulting from the cut-out 90. The lip portion 92 includes a V-shaped section 92a for engaging with the head portion 70 of the locking member 64. The biasing member 88 is formed with a slight curvature to impart a biasing force on the locking member 64 when coupled to the locking member 64 and positioned within the recess 32.
With still further reference to Figures 3 and 6, the intermediate length 73 of the locking member 64 engages within the T-shaped cut-out 90 of the biasing member 88 such that a portion 90a of the biasing member rests on shoulders 72a of the locking member 64. As the biasing member 88 is moved slightly longitudinally, the V-shaped portion 92a of the lip portion 92 slides over the head portion 70 such that the head portion 70 is captured in the V-shaped portion 92a, as shown in Figure 7.
When the rotator 36 is in the "locked" position shown in Figure 3, the base plate 66 is urged upwardly towards the overhanging ledge portions 80 such that the raised surfaces 74 engage within a corresponding pair of notches 86 of the ledge portions 80. When it is desired to reposition the cross bar 20, the rotator 36 may be grasped with two or more fingers of a hand and rotated into an "unlocked" position. This causes the camming surface 62 to urge the head portion 70, and thus the entire locking member 64, downwardly against the biasing force of the biasing member 88 to cause the raised surfaces 74 to move out of engagement with the notches 86, as shown in Figure 4. When the rotator 36 is urged fully into the unlocked position, the head portion 70 and V-shaped lip portion 92a move into contact with the flat portion 62a of the camming surface 62. At this point, the rotator 36 may be released and the flat portion 62a holds the locking member 64 in its unlocked position. While the rotator 36 is in the unlocked position, the entire bracket member 24 may be slid freely along its outer side rail 16 to a new desired position. Once the rotator is repositioned, the rotator 36 may be urged back into the locked position and the force provided by ~he biasing member 88 again urges the head portion 70 of the locking member 64 upwardly until the raised surfaces 74 engage within a new pair of notches. In this regard, it will be appreciated that if the raised surfaces 74 of the locking member 5 64 are not positioned directly underneath a pair of notches 86, that a further degree of slight longitudinal adjustment will be required of the bracket member 24 before the raised surfaces 74 will engage with a corresponding pair of notches 86.
The bracket members 24 of the vehicle article carrier 10 also form a gradually curving profile, as shown in Figure 3, which is aerodynamically advantageous as well as aesthetically pleasing when the bracket members 24 are secured to their respective outer side rails 16. The rotator outer surface 48 remains substantially flush with the outer surface 28 of its 15 bracket member 24 regardless of the rotational position of the rotator 36. Since each bracket member 24 is positively clamped to its associated side rail, there is virtually no wobble, vibration or other objectionable movement or noise generated as the vehicle travels over rough terrain, which occurs with some 20 prior developed article carrier systems. The rotator 36 further allows the bracket member 24 to be quickly and easily clamped and unclamped from the outer side rails 16 to allow the cross bar 20 to be readily repositioned along the outer side rails 16 if repositioning of the cross bar 20 is needed. The vehicle article 25 carrier 10 further accomplishes securing of the brackets 24 to the outer side rails 16 with a minimum number of moving component parts and without complex construction techniques. The bracket housing 26 is preferably molded from a suitable high-strength plastic. The locking member 64 is preferably formed from a single section of metal. The rotator 36 is also preferably molded from a single piece of suitably strong plastic.
Those skilled in the art can now appreciate from the foregoing description that the broad teachings of the present invention can be implemented in a variety of forms. Therefore, while this invention has been described in connection with particular examples thereof, the true scope of the invention should not be so limited since other modifications will become apparent to the skilled practitioner upon a study of the drawings, specification and following claims.
Some vehicle article carriers are adjustable via one or more cross bars which may be adjustably positioned along a pair of raised side rails fixedly secured to an outer body surface of the vehicle. Such vehicle article carriers are shown in, for example, U.S. Patent Nos. 4,684,048, 4,982,886 and 5,082,158, all assigned to the assignee of the present application.
The vehicle article carriers in use at the present time and those embodied in the above-mentioned U.S. patents have proven to be very useful for the purpose of transporting articles which are either too large or awkward to be transported within the interior of a vehicle. Nevertheless, there still remains a need for a vehicle article carrier having a means for adjusting 2 J 92 ~C/

The depressions allow the fingers of a hand to easily grasp the central member to rotate the rotator.
The preferred embodiments thus include a minimum number of moving parts to accomplish locking and unlocking of the bracket member at desired locations along the length of an associated side rail. The clamping engagement provided by the locking member of each bracket member and the engagement of the raised surfaces with a corresponding pair of the notches in the channel member serve to provide extremely secure clamping of the cross bar at a large plurality of desired locations along the side rails.

With further reference to Figure 3, each outer side rail 16 includes an outer wall 76, an inner wall 78 and a pair of overhanging ledge portions 80 which help to form a channel 82.
The outer side rails are each supported on an optional mounting pad 84 and secured to the outer body surface 14 of the vehicle 12 (Figure 1) via threaded screws in the conventional manner.
Each outer side rail 16 is preferably roll-formed from a single piece of suitably strong material such as steel, but it could also be formed from multiple sections of material secured together with suitable fastening elements.
With further reference to Figures 3 and 7, it can be seen that the overhanging ledge portions 80 each include a plurality of spaced-apart notches 86. The notches 86 are adapted to engage with the raised surfaces 74 of the locking member 64 when the locking member 64 is urged into the locked position, as shown in Figure 3. This feature of the present invention will be described more fully in the following paragraphs. It will also be appreciated that the notches 86 could alternatively be formed so as to extend completely through the overhanging ledge portions 80 if desired. It will also be appreciated that conventional side rails without notches could also be employed and still provide excellent securing of the cross bar 20 at a desired location along the side rails 16.
With further reference to Figures 3 and 6, the bracket member 24 also includes a biasing member 88. The biasing member 88, as shown in Figure 6, is formed from a length of spring steel having a T-shaped cut-out 90 and a lip portion 92 resulting from the cut-out 90. The lip portion 92 includes a V-shaped section 92a for engaging with the head portion 70 of the locking member 64. The biasing member 88 is formed with a slight curvature to impart a biasing force on the locking member 64 when coupled to the locking member 64 and positioned within the recess 32.
With still further reference to Figures 3 and 6, the intermediate length 73 of the locking member 64 engages within the T-shaped cut-out 90 of the biasing member 88 such that a portion 90a of the biasing member rests on shoulders 72a of the locking member 64. As the biasing member 88 is moved slightly longitudinally, the V-shaped portion 92a of the lip portion 92 slides over the head portion 70 such that the head portion 70 is captured in the V-shaped portion 92a, as shown in Figure 7.
When the rotator 36 is in the "locked" position shown in Figure 3, the base plate 66 is urged upwardly towards the overhanging ledge portions 80 such that the raised surfaces 74 engage within a corresponding pair of notches 86 of the ledge portions 80. When it is desired to reposition the cross bar 20, the rotator 36 may be grasped with two or more fingers of a hand and rotated into an "unlocked" position. This causes the camming surface 62 to urge the head portion 70, and thus the entire locking member 64, downwardly against the biasing force of the biasing member 88 to cause the raised surfaces 74 to move out of engagement with the notches 86, as shown in Figure 4. When the rotator 36 is urged fully into the unlocked position, the head portion 70 and V-shaped lip portion 92a move into contact with the flat portion 62a of the camming surface 62. At this point, the rotator 36 may be released and the flat portion 62a holds the locking member 64 in its unlocked position. While the rotator 36 is in the unlocked position, the entire bracket member 24 may be slid freely along its outer side rail 16 to a new desired position. Once the rotator is repositioned, the rotator 36 may be urged back into the locked position and the force provided by ~he biasing member 88 again urges the head portion 70 of the locking member 64 upwardly until the raised surfaces 74 engage within a new pair of notches. In this regard, it will be appreciated that if the raised surfaces 74 of the locking member 5 64 are not positioned directly underneath a pair of notches 86, that a further degree of slight longitudinal adjustment will be required of the bracket member 24 before the raised surfaces 74 will engage with a corresponding pair of notches 86.
The bracket members 24 of the vehicle article carrier 10 also form a gradually curving profile, as shown in Figure 3, which is aerodynamically advantageous as well as aesthetically pleasing when the bracket members 24 are secured to their respective outer side rails 16. The rotator outer surface 48 remains substantially flush with the outer surface 28 of its 15 bracket member 24 regardless of the rotational position of the rotator 36. Since each bracket member 24 is positively clamped to its associated side rail, there is virtually no wobble, vibration or other objectionable movement or noise generated as the vehicle travels over rough terrain, which occurs with some 20 prior developed article carrier systems. The rotator 36 further allows the bracket member 24 to be quickly and easily clamped and unclamped from the outer side rails 16 to allow the cross bar 20 to be readily repositioned along the outer side rails 16 if repositioning of the cross bar 20 is needed. The vehicle article 25 carrier 10 further accomplishes securing of the brackets 24 to the outer side rails 16 with a minimum number of moving component parts and without complex construction techniques. The bracket housing 26 is preferably molded from a suitable high-strength plastic. The locking member 64 is preferably formed from a single section of metal. The rotator 36 is also preferably molded from a single piece of suitably strong plastic.
Those skilled in the art can now appreciate from the foregoing description that the broad teachings of the present invention can be implemented in a variety of forms. Therefore, while this invention has been described in connection with particular examples thereof, the true scope of the invention should not be so limited since other modifications will become apparent to the skilled practitioner upon a study of the drawings, specification and following claims.
