Description of Preferred Embodiments
Referring now to the drawings, and more particularly to FIGS. 1 and 2, there is shown generally at 10 the vehicle rack of the present invention and which comprises essentially a support rail 11 having opposed supporting brackets 12, which maintain the rail elevated transversely over a vehicle roof 13. The brackets 12 are removably connected to a respective one of a pair of connecting bases 14, each of which is attached to the vehicle roof 13 on a respective side thereof by attachment means in the form of a hook assembly 15 or a hook plate 28, as shown in FIGS. 6 and 7. Flexible or rigid connecting means 16 in the form of a metal band, or a band having at least a portion thereof made of stretchable material, is interconnected between the connecting bases 14. The connecting bases are rigidly secured to the roof 13 by tensioning means which may consist of a pulling force exerted by the flexible band 16, or an adjustable tensioning mechanism 17, as shown in FIG. 3. Only one of the brackets of each rack has a latch mechanism to lock the rack to the bases and accordingly the rack is secured from one side of the vehicle only.
Referring now to FIGS. 3 to 11, there will be described the construction and operation of the connecting bases which are secured to the vehicle roof. One of the connecting bases 14 is a locking base, as shown in FIGS. 3 to 5, and provided with an adjustable tensioning mechanism 17. The other connecting base is illustrated at FIG. 8. As shown in FIGS. 3 to 5, the locking base is a generally rectangular base having a flat bottom wall 18 and a short circumferential side wall 19. A latch engageable means in the form of a pair of fixed transverse pins 20 are secured elevated from the base wall 18 between a pair of vertical flanges 21. These latching engageable means or transverse pins 20 are positioned to each side of an opening 22 disposed on the central transverse axis of the base wall adjacent an inner longitudinal edge 19' of the base wall. The adjustable tensioning mechanism 17 comprises a connecting housing 23 secured above the base wall 18 adjacent the opening 22 and has a threaded bore 24 therein aligned with the central transverse axis 25. A cushioning material, herein a rubber pad 26, is secured over the rear face of the base wall 18 to protect the vehicle roof.
A pair of apertures 27 is also provided in the base wall 18 adjacent an outer edge 19" thereof for removable securement of the metal strap 38, as shown in FIG. 8. Alternatively, slots (not shown) may be formed in the base wall 18' to receive hooks 30 of a hook plate 28. These apertures also provide drainage for water falling on the base wall 18 of the base 14. The hook plate 28 is formed of metal and has a slight curved wall and a hook end 29 for clamping retention with a restraining portion of the vehicle adjacent the roof thereof, such as a gutter or the top edge of a door opening. The other end of the hook plate is formed with attachment fingers, herein in the form of a pair of outwardly facing hooks 30, which engage into respective apertures 27 provided in the base wall 18 of the locking connecting base 14. The drawings illustrate the preferred hook assembly 15 shown in FIG. 8.
As shown in FIGS. 9 and 10, the flexible connecting means 16 is herein constituted by a band 31 of metal having a protective material 32 over the rear face thereof. The band 31 may have a slight curvature, as shown in FIG. 10, and has upwardly turned end portions 33 provided with an aperture 34. The other end has a hook formation 33'. The end portions 33 constitute a vertical end wall with one of these end walls extending in the opening 22 in the base wall 18 of the locking connecting base 14. As shown in FIG. 5, one end wall 33 is connected to the threaded housing 23 by a threaded bolt 34 having a head 35 for receiving the end of a tool, such as a screwdriver or allen key (not shown), to cause the band 31 to be displaced in the direction of arrow 36 to apply tension between the connecting bases 14 and the hook plates 28 secured to the vehicle gutters of the edge of the door opening. Accordingly, the connecting bases are rigidly and immovably secured to the roof of a vehicle in a position to receive the supporting brackets and the rail therein.
The other end wall 33 of the band 31 is connected to the other connecting base 14', as shown in FIG. 8, by simply inserting the end wall 33 into a slot 37 formed adjacent the inner circumferential wall 19'. As shown in FIG. 8, the hook plate 28' is herein constituted by a metal strap 38 secured to the base wall 18' of the connecting base 14' and provided with a series of attaching apertures 39 to receive therein an attaching pin 40 secured to the end of a hook bracket 41 having a hook end 42 to engage with a vehicle gutter or the edge of a door frame. The outer wall 19" of the circumferential wall 19 is also provided with a pair or more of slots 43 to receive the prongs 44 formed in an outer side wall 45 of one of the support brackets, herein bracket 12', which is not provided with a latch mechanism, as will be described later.
As shown in FIG. 11, the flexible connecting means 16 may also be formed as a belt of stretchable material, or having at least a portion thereof as shown at 46 made of stretchable material. Accordingly, the belt also constitutes a tension means for securing the connecting bases 14 and 14' to the vehicle roof. The housing is installed by firstly connecting one of the hook plates 28 to the gutter on one side of the vehicle and by pulling on the other hook plate 28 on the other side of the vehicle. The band 16 is stretched with the other hook plate being attached to the gutter. The pulling force in the stretchable band then retains the assembly connected on the roof. However, the preferred embodiment is the adjustable tensioning means 17 and the rigid band 31 whereby the support connecting bases are more rigidly connected to support heavy loads and cannot be removed without the use of a special hand-tool necessary to turn the threaded bolt 34.
When the rack is not in use the connecting bases 14 and 14' may be provided with a cap 47, as shown in FIGS. 2 and 16. The cap 47 is formed of a flexible rubber-like material and provided with a circumferential slot 48 to receive the circumferential wall 19 of the base 14 in friction fit therein. Other inner depending ribs 49 may also be provided to rigidly connect the cap over the bases. As shown in FIG. 16, the cap also has an aerodynamic design to prevent wind resistance and noise. The cap, the connecting bases and band may also be painted with a color to blend with the color of the vehicle.
Referring now to FIGS. 12 to 15, there will be described the construction and operation of the supporting bracket, and more specifically the locking supporting bracket 12 which is a very important characteristic of this invention. As herein shown, the locking support bracket 12 is provided with a latch mechanism 50 for engaging the latching engageable means or transverse pins 20 extending above the base wall of the locking connecting base 14. The latch mechanism 50 comprises a lever arm 51 which is pivotally secured between opposed support side walls 52 of the locking bracket 12 and displaceable on a fixed rotation axis about a transverse pin 53 secured to a bracket 54 inwardly of the side wall 52. As shown in FIG. 13, there are two latch mechanisms 50 spaced apart within the locking bracket 12, and only one need be described herein as they are both identical. A latch element 54 is pivotally attached at a top end 56 to a latch pivot pin 57 in a top part of the lever arm 51 above the fixed axis of rotation which is the transverse pin 53. The pivot pin 57 interconnects the top end 55 of the latch element 54 to the top end 56 of the lever arm 51. Accordingly, the pivot connection or pin 57 of the latch element 54 is displaceable on an arc 58 extending about the fixed rotation axis or transverse pin 53. Finger engaging means in the form of a plate 59 of FIG. 13 is secured to the lever arm(s) 51 to displace the arms on the fixed rotation axis, transverse pin 53.
As shown in FIG. 13, the latch element 54 is a flat plate-like latch formed of two latch sections positioned on each side of the lever arm 51. With further reference to FIGS. 14A and 14B, it can be seen that by lifting the finger engaging plate 59 outwardly in the direction of arrow 60 thereby retracting same from the locking bracket, the free hook end 61 at the bottom of the latch element causes the latch pivot connection or pivot pin 57 to be displaced in a predetermined direction on the arc 52, forwardly as indicated by that arc, about the fixed pivot transverse pin 53. This causes the hook end 61 to firstly move downardly, as shown in FIG. 14A, and out of engagement with its associated transverse pin 20 secured to the locking connecting base 14. As the plate 59 is further moved outwardly, as shown in FIG. 14B, the latch element abuts the transverse pin 53 and slides downwardly thereon so as to wedge it or guide the latch element and the hook end 61 away from the transverse pin 20 to permit the removal of the locking bracket 12, moving it upwardly, from the locking connecting base 14 and at the same time disengaging the opposed bracket 12' from the opposed base 14', as shown in FIG. 8.
A key lock housing 65 having a key slot 66 therein is mounted on the plate 59 to lock the plate onto an outer transverse wall 67 of the bracket 12 to prevent removal of the rack from the bases.
Each bracket 12 and 12' is provided with a pivotal rail connector 68 in a top portion thereof for removably connecting the rail 11 thereto. The rail connector is herein constituted by a hollow tubular housing of rectangular cross-section and dimensioned for receiving, in sliding fit therein, an end portion of the rail 11. The bottom wall 69 of the connector is slit and the side walls 70 have lower extensions 71 which connect to a clamping screw 72 whereby rotation of the clamping screw applies clamping pressure between the side walls 70 to frictionally retain the rail 11 therein. The other pivotal rail connector 68 may have an end wall to receive the other end portion of the rail 11 therein, and need not have a locking screw 72 secured thereto, as once the rail is connected to the connector 68 of the locking bracket 12, it cannot be detached from the other rail connector in the other non-locking bracket 12', as is obvious.
Referring now to FIGS. 12, 13 and 15, it can be seen that the opposed support walls 52 of the brackets 12 and 12' are provided with a flange end section 75 for pivotally connecting the hollow rail connector 68 therebetween. The extension side walls 71 of the connector are secured between the flange end sections 75 by a pivot pin 76 and, depending on the arc of the roof of a vehicle, the connector 68 will self-adjust its angular position with respect to the walls 52. The screw 72 is then tightened to preserve the connected angle.
As shown in FIGS. 13 and 15, two or more slots 79 may be formed in an inner surface 77 of the opposed flange end section 75 and disposed on spaced radii of the pivot pin 76. An arresting protrusion 78 is formed on opposed wall extensions 71 for arresting engagement with one of the slots 79. As also shown in FIG. 13, the brackets taper outwardly to provide rigidity to its housing construction and are further provided with an inner transverse wall 80 to strengthen the opposed side walls 52.
As can be appreciated, with the vehicle rack of the present invention the rail and brackets are easily and quickly removable from the connecting bases which remain connected to the roof of a vehicle. Also, the rail 11 is easily removable from the support brackets and various article securing elements 81 of FIG. 17 can be slid onto the rail and secured thereto. These elements 81 may also be clamped onto the rail without having to be slid from the end thereof. As shown in FIG. 17, these elements may consist of a ski-holding bracket 82 or a bicycle support bracket 83, or simply a strap-attaching bracket, as shown at 81. It is, of course, within the ambit of the present invention to cover any obvious modifications of the preferred embodiment described herein provided such modifications fall within the scope of the appended claims. As an example only, there may be a single latch mechanism 50 in the securing bracket 12 engaging a single engageable pin 20 in the connecting base 14. Although, the brackets herein described are constructed of metal posts, other suitable material may be substituted.
As shown in FIG. 1, the connecting means, i.e., the band 16, may be formed by short hook brackets 16' which may hook onto the side edge of a sunroof opening 9,. When such is provided whereby not to interfere with the operation of the sunroof 8.
