Description

Technology Field

[0001] The present invention relates to a frame for a tarpaulin installed in the cargo compartment of a truck, and more specifically, to a tarpaulin frame for a truck having a semi-removable structure that allows for full opening for the unloading of large cargo. Background Technology

[0002] Generally, tarpaulin frames for trucks are installed in the cargo bed so that they can be unfolded or folded by sliding back and forth in an accordion-like manner.

[0003] However, recently, as shown in FIG. 1, a curved frame has also been proposed in which the columns installed at the four corners are configured as height adjustment bars (300) to allow the upper structure (200, 400) to be adjusted up and down.

[0004] However, the conventional tarpaulin frame for cargo trucks as described above was practically impossible to unload using a forklift, such as with large cargo, due to the problem of hitting the upper guide rail (400).

[0005] In addition, depending on cargo transportation or other needs, it is sometimes more convenient to operate the vehicle with the tarpaulin frame practically removed; however, there was a limitation in that this was difficult to implement with the conventional installation structure described above.

[0019] A cargo truck frame (10) according to an embodiment of the present invention includes a front section left post (11) and a front section right post (12) that are fixedly installed at the left and right corners of the front section of the cargo box (1) of the cargo truck as shown in FIG. 2, and a rear section left post (13) and a rear section right post (14) that are fixedly installed at the left and right corners of the rear section of the cargo box (1).

[0020] Additionally, the cargo truck frame (10) includes a left pivot beam (15) in which the front and rear ends are connected and joined to the upper end of the front left post (11) and the upper end of the rear left post (13), and a right pivot beam (16) in which the front and rear ends are connected and joined to the upper end of the front right post (12) and the upper end of the rear right post (14).

[0021] The left rail (17) and the right rail (18) are integrally joined on the upper surfaces of the left pivot beam (15) and the right pivot beam (16).

[0022] As shown in FIG. 3, the front portions of the left pivot beam (15) and the left rail (17) are connected to the front portion left post (11) via a hinge (19), so that they can pivot into the interior of the cargo box (1 in FIG. 2) based on this.

[0023] The right pivot beam (16 in FIG. 2) and the right rail (18) are also connected to the right post (12) of the front section via a hinge (not shown in the drawing) of the front section, so that they can pivot into the interior of the cargo box (1) based on this.

[0024] As shown in FIG. 4, the rear end of the left pivot beam (15) and the left rail (17) is detachably fitted and connected to the insertion coupling tube (13a) and the second insertion coupling tube (13b) formed protruding forward from the upper end of the left post (13) of the rear end.

[0025] The rear end of the right and left pivoting beam (16) and the right rail (18) is also the rear end right post

[0026] The insertion coupling tube (not shown in the drawing) formed protruding forward at the upper part of (14 of FIG. 2) and the second insertion coupling tube (not shown in the drawing) are detachably fitted and coupled.

[0027] Meanwhile, as shown in FIGS. 2 and 5, the left pivot beam (15) and the left rail (17) are each divided in half along the front-rear longitudinal direction and are configured to be foldable by being joined to each other via a hinge (20), and the right pivot beam (16) and the right rail (18) are also likewise divided in half along the front-rear longitudinal direction and are configured to be foldable by being joined to each other via a hinge (21 in FIG. 2).

[0028] Additionally, the roof frame (10) for a cargo truck further includes a plurality of roof frames (22) as shown in FIGS. 2 and 6. The roof frames (22) are connected so that the lower end of a vertically extending left column section (22a) can slide back and forth along a left rail (17) via a roller assembly (23), and the lower end of a vertically extending right column section (22b) can also slide back and forth along a right rail (18) via a roller assembly (23).

[0029] The roof frame (22) has a horizontal beam section (22C) that connects the upper part of the left column section (22a) and the upper part of the right column section (22b), and extends in a direction across the storage box (1).

[0030] When the left rail (17) is separated from the rear end left post (13) together with the left pivot beam (15) as shown in FIG. 4, the roller assembly (23 in FIG. 6) inserted therein can be removed through the rear end of the left rail (17) or, conversely, inserted through it.

[0031] The roller assembly (23) inserted into the right rail (18) can also be inserted and removed through the rear end of the right rail (18), so the roof frame (22) itself can be connected to or separated from the left and right rails (17, 18).

[0032] As shown in FIG. 6, the roller assembly (23) is inserted into a rail (17) that forms an open channel at the top and is supported by rolling contact with the inner wall surface of the rail (17) through left and right rollers (23a, 23b), and is supported by rolling contact with the bottom surface of the rail (17) through four lower rollers (23c).

[0033] The upper part of this roller assembly (23) is connected to the lower part of the left and right column parts (22a, 22b) of the roof frame (22) through the upper part of the rail (17) which is open in a channel shape, and is formed as a single unit.

[0034] According to the roof frame (10) for a cargo truck configured as described above, all roof frames (22) can be transferred to the front end of the cargo box (1) and gathered together as shown in FIG. 7, or additionally, the left and right pivot beams (15, 16) and left and right rails (17, 18) can be folded in half as shown in FIG. 8. Furthermore, all roof frames (22) can be pulled out through the rear end of the left and right rails (17, 18) that have been folded in half, and the front end of each of the left and right pivot beams (15, 16) and left and right rails (17, 18) that have been folded in half can be pivoted inward again based on the front end left and right posts (11, 12) and folded as shown in FIG. 9.

[0035] At this time, the left and right pivot beams (15, 16) that cannot be completely folded due to overlapping each other can be folded so that they are closely and completely overlapped vertically by installing them with a slight height difference from each other. The left and right pivot beams (15, 16) that are completely folded in this way can be secured by tying them with a belt or the like.

[0036] In this way, the fully open cargo box (1) allows for convenient loading and unloading of cargo by opening the wall (1a), or the vehicle can be used in this fully open form when the installation of a tarpaulin is unnecessary.
