Description

Utility model application

Beam folding type sideboard structure

DOMAIN

This application relates to motorhome accessories and in particular to a sideboard structure of the foldable beam type.

PRIOR ART

Surface-type folding is generally employed by an existing folding sideboard that has a large folding volume, and poor anti-tipping performance for structural reasons. In addition, a grip structure is generally employed by the existing beam collapsible type sideboard which is difficult to assemble and disassemble and results in poor using experience.

SUMMARY

To overcome the above-mentioned drawbacks, a beam collapsible type buffet structure is provided according to the present application, which is convenient to disassemble and assemble, has a small folding volume, and is stable and reliable in use.

To solve the aforementioned technical problems, the following technical solution is provided according to the present application: a collapsible beam type buffet structure comprises a collapsible frame, wherein the collapsible frame comprises a collapsible assembly and multiple support rods which are hinged on the collapsible assembly, and the collapsible assembly is configured to be folded inward to cause the support rods to approach each other for folding.

During use, the collapsible assembly is unfolded outward, the support rods are unfolded outward together with the collapsible assembly and are supported on the ground, then a table board is mounted on the collapsible frame, and the complete sideboard is constructed, the sideboard having a stable and reliable support and not easily toppled over. During folding, the table panel is first pulled out, then the folding assembly is folded inward to make the support rods close to each other for folding, realizing the folding of the complete sideboard. The sideboard has a small volume after folding, and is convenient to carry. In actual use, the complete collapsible frame is connected with a fabric envelope, and a housing space is formed inside the fabric envelope for storage. The beam folding type buffet structure is convenient to disassemble and assemble, has a small folding volume, and is stable and reliable in use.

Preferably, an upper collapsible assembly and a lower collapsible assembly are provided, and an upper part and a lower part of each support rod are hinged to the upper collapsible assembly and the lower collapsible assembly respectively. The arrangement of the upper folding assembly and the lower folding assembly greatly improves the support stability of the complete sideboard.

Preferably, the collapsible assembly includes a collapsible seat and multiple collapsible rods which are in one-to-one correspondence with the support rods, where one end of each collapsible rod is hinged to the corresponding support rod, and the other end of the collapsible rod is hinged to the collapsible seat.

The folding seat moves to cause the folding rods to rotate, so as to realize the unfolding and folding of the folding assembly, which has a simple structure and convenient operation.

Preferably, a rotatable limiting lock member is mounted on the folding seat, extension sections are respectively provided at the ends of at least one pair of folding rods, the extension sections are mounted on the folding seat, escape grooves, corresponding to the extension sections, are defined in the limiting locking element; the limiting lock member is rotated so that the escape grooves are misaligned with the extension sections, and the extension sections are supported on the limiting lock member to lock the folding rods.

After the collapsible seat is put in place and the collapsible assembly is unfolded in place, the limiting locking member is rotated, and the escape grooves in the limiting locking member are misaligned with the sections of extension, and at this time, the limiting lock member covers the extension sections, and limits positions of the extension sections, so that the extension sections cannot rotate, which ensures the stable support from the full buffet.

Preferably, hinge grooves, corresponding to the collapsible rods, are defined in the collapsible seat, and one end of each collapsible rod is hinged in the corresponding hinge groove. Hinge grooves make it easy to connect the folding rods to the folding seat.

Preferably, a handle is connected to the folding seat, and is firmly connected to the limiting locking element. The folding seat is pulled by the handle to move, and the handle rotates to cause the limiting locking member to rotate after the folding seat is put in place, to lock the folding rods. During folding, the folding rods can be unlocked by simply turning the handle, and the handle is pulled for folding, which is convenient.

Preferably, an arcuate groove is defined in the limiting locking member, a positioning pin is provided on the folding seat, and the positioning pin is inserted by moving into the arcuate groove. When one end of the arcuate groove abuts the locating pin during rotation of the limiting lock member, it indicates that the limiting lock member has been rotated into place. Such a structural arrangement ensures the precision of the rotational position of the limiting locking element, which facilitates the folding and unfolding of the collapsible assembly.

Preferably, link seats, corresponding to the collapsible rods, are mounted on the support rods, a link groove is defined in each link seat, one end of each collapsible rod is hinged in the corresponding link groove, a cover is provided on each link seat, the limit cover is covered on one side with the corresponding link groove, and each collapsible rod is configured to abut the corresponding limit cover when unfolded to a horizontal position. The connection between the folding rods and the support rods is convenient and reliable.

Preferably, a table board is mounted on the folding frame, an upper end of the folding frame is connected to cross support rods, multiple C-shaped clamps are mounted on a bottom surface of the table board, and the clamps are pressed onto the cross support rods. The table board is pressed to the supporting cross rods through the clamps, which is convenient for disassembly and assembly.

Preferably, one end of each support cross rod is hinged to a support rod, and the other end of this support cross rod is removably attached to another support rod. During folding, one end of each support cross rod is first withdrawn from a support rod, then this support cross rod is turned down to abut against another support rod, which is convenient for assembly and folding.
