Utility Model Embodiments

The device for locking the tailgate of a vehicle’s cargo platform (hereinafter referred to as the “device” or “device 1”) is generally designed to lock and lock in the working position the folding (and / or removable) sides of the vehicle’s cargo platforms. As shown in FIG. 1, the device 1 is mounted on a rack 2 of a cargo platform 3 of a vehicle (for example, a cargo body of a vehicle, trailer or semi-trailer). The rack 2 is mounted on the platform 3. On the platform 3, the hinged sides 4 are also pivotally mounted. Each rack 2 can accommodate one, two or more devices 1. For example, in FIG. 1 shows devices 1 located on the corner and intermediate racks 2 of platform 3. Device 1 can also lock and fix in the working position the awning racks of the side or curtain racks of the side (not shown in the figures).

The design of device 1 is shown in more detail in FIG. 2A-2B. The device 1 contains a base 6, made mainly in the form of a U-shaped or C-shaped metal profile. One end of the base 6 has a side wall with an opening for reliable retention of the rod in a movable state. The base 6 of the device 1 is intended for rigid fastening to the rack 2, for example, by means of a bolt, screw or welded connection.

The device 1 also has a handle 7 (drive lever), an intermediate link 8, a slider 9 and a stem 10 (or a valve). In FIG. 2A-2B, the handle 7 is shown in the closed position. In FIG. 3 shows the construction of the handle 7 in more detail. The handle 7 has a complex profile, partially U-shaped. On the handle 7 there are holes 11 for the hinge 12 connecting the handle 7 with the intermediate link 8. On the handle 7 there are also holes 13 for the hinge 14 connecting the handle 7 with the base 6 and the stem 10. On the handle 7 there may also be a groove 15 located with the side facing the base 6 of the device 1. The groove 15 is designed to connect to the latch (not shown in the figures) of the device 1 for reliable fixation of the position of the handle 7 in the closed position and to protect the sides 4 from opening while the vehicle is in motion. As shown in FIG. 3, the groove 15 may have a radial fillet on the handle 7.

Returning to FIG. 2A-2B, in the device 1, the intermediate link 8 is connected to the slider 9 by a hinge 16. Thus, when the handle 7 is moved by the user, the applied force is transmitted to the slider 9 through the pivotally connected intermediate link 8, as well as to the pivotally mounted rod 10. Stem 10 made, for example, in the form of a metal profile of any suitable section. The rod 10 passes through a hole in the end face of the base 6 and can move along the guides placed in the rack 2.

The device 1 also contains a spring 17, which is located mainly around the rod 10 and is fixed on the base 6 and the handle 7 so that provides elastic translational movement of the rod 10 within the specified limits. The device 1 may also additionally contain a torsion spring 18 placed on the hinge 12 connecting the handle 7 with the intermediate link 8. The springs 17 and 18 provide a more reliable and convenient fixation of the sides 4 on the posts 2 by creating compressive (or tensile) forces on the structural elements devices 1.

The device 1 may also include at least one rod 19, mounted on the rod 10 and designed to interface the rod 10 with the side 4 of the cargo platform 3. In particular, the side 4 has a slot 5 for receiving the rod 19 (or rod 10 in some implementations) . Socket 5 is in the form of a cylinder, groove or sleeve. The rod 19 may have a conical or hemispherical end to facilitate the movement and fixation of the rod 19 in the socket 5. The rod 19 can be mounted on the side surface of the rod 10 so that the Central axis of the rod 19 is parallel offset from the Central axis of the rod 10. The length of the rod 19 may be different in different embodiments of the utility model. For example, increasing or decreasing the length of the rod 10 makes it possible to use the device 1 for different heights of the sides 4. Depending on the location of the rod 19 with respect to the rod 10, the device 1 can be classified as “left” or “right”. The number of rods 19 may be different. For example, the device 1 with additional welded rods 19 can be used in the racks of 2 awning vans. However, the use of the rod 19 is optional. For example, when implementing device 1 without a rod 19 and with a short rod 10, device 1 can be used in intermediate racks 2, where the connection of the rack 2 with the side 4 occurs using an ear welded on the rack 2.

The slider 9 can be made of a metal profile of complex shape with the possibility of its articulation with an intermediate link 8 and the possibility of its sliding and translational movement along the guides (not shown in the figures) installed in the rack 2. The slider 9 is made with a beveled surface located with side opposite to the edge of the platform 3 (i.e., from the side opposite to the side where the hinge 16 is located), which improves the convenience and reliability of its interface with the platform 3. In particular, the slider 9 pr dnaznachen for interfacing with a bracket 20 rigidly fixed on the platform 3. The bracket 20 is shown in more detail in FIG. 4A and 4B. The brackets 21 are welded to the bracket 20, the angle of inclination to the vertical plane of which is predominantly equal to the angle of inclination of the beveled surface of the slider 9. The inner surface 22 of the bracket is also beveled and generally repeats the beveled surface of the slider 9. Practice has shown that such a design of the bracket 20, the brackets 22 and the slider 9 improves the reliability of the connection of the device 1 with the platform. In some embodiments of the utility model, two or more sliders 9 may be used. For example, two sliders 9 may be used in a device 1 for curtain racks.

The device 1 operates as follows (according to one embodiment). When turning (lowering) the handle 7 from an open position to a closed position, the rod 10 performs translational movement in one direction to mate with the side 4 of the cargo platform 3 through the slot 5, and the slider 9 translates along the guides in the predominantly opposite direction to interface with the platform 3 of the vehicle through the connecting bracket 20. When the handle 7 is fully lowered, the spring-loaded rod 10 lifts the rod 19 and inserts it into the socket 5, thereby connecting the rack 2 with the side 4, and crawled n 9 is fixed in the bracket 20, thereby connecting the board 4 with the platform 3. For tilting the boards 4, the handle 7 is lifted and the rod 19 is disengaged from the socket 5, releasing the board 4 reclining. By further lifting the handles 7, the slider 9 is disengaged from the bracket 20 so that the post 2 is released from fixing to the platform 3.

Thus, the device 1 of this utility model, in comparison with the known analogues and prototype, has increased reliability. This is achieved, for example, due to the simultaneous fixation by the device 1 of the sides 4, the rack 2 and the platform 3, as well as by preventing the spontaneous folding of the sides 4. In addition, the device 1 provides a more convenient operation of the device, for example, by using a large lever, which reduces the complexity of unlocking or locking the sides 4.
