Description

Joint assembly and display rack with the joint assembly

This case relates to a joint assembly and a display stand with the joint assembly, and particularly relates to a joint assembly that can be randomly assembled and a display stand with the joint assembly.

With the progress of the times, modern people pay more and more attention to and cultivate the literary and artistic atmosphere, and together with the rise of artistic and cultural activities and cultural and creative industries, museums or art galleries in various places often hold various special exhibitions in addition to their standing collections of cultural relics. In addition, with the rise of the society's awareness of copyright protection and the improvement of creative value, some individual artists, studios or art departments also commonly prepare various works exhibitions.

The creator of this case, based on the involvement, promotion and management of related fields, has experienced some common display rack structure problems on the exhibition hall, so he proposed a solution and proposed the creation of this case.

The conventional display racks can be roughly divided into (1) welded display racks and (2) detachable display racks (or "combined display racks").

Conventional welded display racks often do not have joint components. They are formed by connecting multiple frames (such as but not limited to aluminum pipes, iron pipes, etc.) by welding. They are bulky and heavy, and it is difficult to avoid damage to the display rack. It is extremely inconvenient to disassemble and assemble the display rack under the premise, when it is transported, moved or stored.

Furthermore, the conventional welded display racks are often unable to arbitrarily adjust the spacing between the frames, and thus cannot be adjusted according to the theme, the difference in the shape and size of the exhibits, or the difference in the spatial layout of the display site.

In addition, the conventional welded display racks are often used for one-time use, which not only increases the cost of the exhibition, but also causes related environmental protection issues.

The conventional modular display rack has the following problems: (1) the joint is conspicuous and abrupt; (2) the direction of the joint is fixed (for example: horizontal two-way, vertical two-way, horizontal three-way, vertical three-way, etc.); (3) ) The number of joints is fixed (for example: two-way, three-way, four-way, etc.); (4) The screw locking direction is fixed (for example: it can only be locked from the outside of the display frame, or can only be locked from the inside of the display frame, etc.) ); (5) Poor support.

Take the new patent "Assembly Frame Assembly and Its Joint Structure" (Certificate No.: M488248) approved and announced by the Republic of China on October 21, 2003 as an example. Figure 2 of the case).

In addition, take the new patent "Combined Frame Structure Device" (Certificate No.: M342074) approved and announced by the Republic of China on October 11, 1997 as an example. The four-way angled joint not only has a fixed joint direction, but also can be assembled. Frames or brackets (two square vertical main frames and two square horizontal brackets) are also fixed (refer to the sixth figure of the case). In addition, the four-way angled joint and the frame or bracket are fixed from the outside by screw locking.

Moreover, some conventional modular display racks have a weak connection between the connector and the frame body, and there is a problem of low supportability. In some situations, the display rack still needs to be equipped with additional supporting elements (for example: Diagonal brace) to strengthen the overall stability.

Therefore, how to propose a display rack structure that can allow users to easily assemble and disassemble, and improve the convenience of transportation, storage, assembly or site restoration; it can be used repeatedly, save costs, and be environmentally friendly; As required, different shapes are assembled randomly to match the appearance of different exhibits or different exhibition display methods; it can have a smooth joint, hidden and stable connection relationship to improve the beauty of the display rack and enhance the exhibition.
