With reference to FIG. 1A, an apparatus 1000 for attaching or holding and securing objects to a vehicle 100, trailer, platform, building, floor or the like. The vehicle may be the top of a car, station wagon, a truck, trailer, pickup, or any other conveyance for transporting or carrying objects.
With reference to FIG. 1A and FIG. 1B the apparatus 1000 comprises at least two rails 1100. The rails 1100 are fixed and attached to the vehicle 100 or the like, each rail 1100 having a channel 1110, with each channel 1110 enclosed by a projection 1120 that is part of the rail. With reference to FIG. 1B the apparatus 1000 includes at least one attachment device 1200, the attachment device 1200 received by the channel 1110 of one of the rails 1100, the attachment device 1200 sliding within the recess formed by the channel 1110 of a rail and its projection 1120, whereby a hook 1202 on the attachment device 1200 attaches or secures an object to the rail by a tether such as a chain, cable or the like 200. The attachment device 1200 is configured to slide within the one rail 1100, and also configured to be immovably fixed at a desired position within the rail 1100 by operating a locking mechanism 1210 1220 that is part of the attachment device 1200. By operating the locking mechanism 1210 1220, the attachment device 1200 is released or unlocked from the channel 1110 so the attachment device 1200 can slide within the one rail 1110, constrained by the projections 1120 of the rail 1100.
In FIG. 2, the rail 2100 is attached to a vehicle 100 by a fastener that passes through an opening 2130 made in the rail 2100.
Again with reference to FIG. 1A, the attachment device 1200 includes a slide 1220, which receives the locking mechanism 1210 1220 and, when constrained by the projection 1120 of a rail 1100, the attachment device 1200 is prevented from moving within the rail 1100. In case of the exemplary embodiment, the locking mechanism 1210 1220 comprises a vertical portion having threads 1205 and a nut 1215, the threads received by threads in the slide 1220 and by combined pressure of the nut 1215, and slide 1220, the attachment 1200 is held in the rail 1100.
With reference to FIG. 2, an exemplary embodiment of a rail 2100 is made from hard, durable material such as metal, plastic or composite substance capable of sustaining heavy loads and high stress. The rail 2100 has a channel 2110, the top of the channel 2110 having a “lip” or projection 2120.
With reference to FIG. 2, the exemplary rail 2100 has means 2130 for attaching the rail 2000 to a floor, building or conveyance. FIG. 2 shows a hole 2130 made at the bottom of the channel 2110, the hole 2130 made to receive a bolt, screw or the like, which will attach the rail 2100 to the floor, building or vehicle.
A Preferred Embodiment of the Attachment Device
With reference to FIG. 3A, an exemplary embodiment of an attachment device 3200 comprises a body 3210 for securing a rope, wire or chain. The body 3210 is made as the handle of a cam lock having cams 3210 3220. The cams of the lock 3210 3220 are made so that when the body is rotated into a vertical position, the cams 3210 3220 lock the attachment device 3200 by wedging upon the projections of the rail. It should be noted that the cams 3210 3220 wedge upon both projections of the rail as opposed to being held by a single portion of the rail as in the Ford Motor attachment device.
Again with reference to FIG. 3A, the attachment device body 3100 has a hole 3115 for receiving a pin 3116, the pin 3116 passing through a hole 3315 in the handle 3110 of the slide 3300, the slide received by the rail. It can be seen that the handle 3110 fits within a slot 3120 of the body 3100, with the handle 3110 made so that the hole 3315 made in the handle 3110 aligns with the hole 3115 in the attachment device body 3100.
With reference to FIG. 3B, when the slide 3300 is received within the rail 3800, and the handle 3110 is attached to the body 3100, the fore 3210 and aft 3220 of the locking cam are placed to engage the projections 3850 of the rail 3800 when the body is rotated with respect to the rail. As the body 3100 is rotated into a vertical position, the cam lock 3210 3220 engages the projections 3850 of the rail 3800, and pulls the slide 3300 up against the projections 3850 of the rail 3800.
With reference to FIG. 3C, when the body 3100 is rotated into a vertical position with respect to the rail 3800, the cam lock 3210 3220 presses down against the top of the rail projections 3850 as the slide 3300 is pulled against the bottom of the rail projections 3850. In this position a rope, chain or the like 3900 is attached to the body 3100 in order to hold an object.
While the invention may be practiced in other embodiments and variations thereof of, it will be appreciated that the invention is most properly defined and delineated by the claims that follow.
