As shown in FIG. 5 , the second wall 20b of the furniture 20 can be installed toward the at least one locking arm 36 along an installation direction Y through the at least one installation portion 30 . The installation direction Y is substantially perpendicular to the imaginary axis direction X, and the installation direction Y is substantially parallel to the at least one latching arm 36 disposed laterally.

As shown in FIG. 6 and FIG. 7 , when the second wall 20b of the furniture 20 is displaced to a predetermined position in the mounting direction Y and is close to the first wall 20a, the mounting end 48 of the at least one mounting portion 30 will contact the The guide section 49 of the first latching portion 46a and the second latching portion 46b of at least one latching arm 36 of the connecting device 32 .

As shown in FIG. 8 and FIG. 9 , when the second wall 20b of the furniture 20 continues to move toward the mounting direction Y, the mounting end 48 of the at least one mounting portion 30 pushes against the first latch of the at least one latching arm 36 The guide sections 49 of the latching portion 46a and the second latching portion 46b respectively drive the first latching arm 36a and the second latching arm 36b to move flexibly around the imaginary axis direction X, so that the first latching arm 36a and the second latching arm 36b move flexibly around the imaginary axis direction X The latching arm 36a and the second latching arm 36b are relatively close to each other. At this time, the first latching arm 36a and the second latching arm 36b are in a state of accumulating an elastic force, and the first latching arm 36a and the The end portion of the second locking arm 36b slightly penetrates into the accommodating area 31 .

As shown in FIG. 10 and FIG. 11 , when the second wall 20b of the furniture 20 is further displaced toward the installation direction Y, the installation end 48 of the at least one installation portion 30 will further pass over the at least one locking arm 36 The first latching portion 46a and the second latching portion 46b enable the first latching portion 46a and the second latching portion 46b of the at least one latching arm 36 to enter the accommodating area 31, wherein once the at least one latching arm 36 After the mounting end 48 of a mounting portion 30 passes over the first latching portion 46a and the second latching portion 46b, the first latching arm 36a and the second latching arm 36b release the elastic force and return to be spaced apart from each other In the state of being separated by a certain distance, the first latching portion 46a and the second latching portion 46b are mutually latched with the mounting end 48 of the at least one mounting portion 30 and are locked at the mounting end of the at least one mounting portion 30 accordingly. 48 walls. Thus, the second wall 20b can be fixedly connected to the first wall 20a by means of the connecting means 32 in a tool-free manner.

It is worth mentioning that at least one mounting portion 30 of the connecting device 32 is detachably disengaged from the first latching portion 46a and the second latching portion 46b. For example, once the user exerts force to deform the first locking arm 36a and the second locking arm 36b (as shown in FIG. 9 ), the first locking portion 46a and the second locking portion 46b The mounting end 48 of the at least one mounting portion 30 is no longer locked, so that the second wall 20b can be separated from the first wall 20a in a dismounting direction opposite to the mounting direction Y.

As shown in FIG. 12 and FIG. 13 , the connecting device 32 further includes a guide portion 50 , and the guide portion 50 is an arc surface or an inclined surface. When the second wall 20b of the furniture 20 has an installation angle deviation B relative to the first wall 20a, the guide portion 50 can be used to guide the second wall 20b of the furniture 20 (as shown in FIG. 14 ). , so as to help the at least one mounting portion 30 to be mounted on the latching portion of the latching arm 36 (for example, the first latching portion 46a and the second latching portion 46b) (for this part, please refer to Fig. 11).

For example, when the second wall 20b of the furniture 20 approaches the first wall 20a in the installation direction Y, if the second wall 20b of the furniture 20 has the installation angle deviation B relative to the first wall 20a (eg 12 ), the mounting end 48 of the mounting portion 30 can be in contact with the guide portion 50 (as shown in FIG. 13 ), thereby guiding the second wall 20b of the furniture 20 (as shown in FIG. 14 ) ), so that the mounting end 48 of the at least one mounting portion 30 can be smoothly locked to the first locking portion 46a and the second locking portion 46b (see FIG. 11 for this part).

As shown in FIGS. 15 , 16 and 17 , after the second wall 20 b of the furniture 20 is removed from the latching parts 46 a and 46 b through the mounting part 30 , another type of plate (for example, wood) can also be used. or other form of solid board), for example, the end 202 of another second wall 200 selected for the furniture 20 can abut the surface 45 of the base 34 of the connecting device 32, and the at least one locking feature 38a can be For providing at least one corresponding locking feature 204 through which the at least one locking member 52 passes and is locked to the other second wall 200 to secure the other second wall 200 to the auxiliary portion 38 so that the other second wall 200 is A second wall 200 can connect the first wall 20a.

Therefore, the connecting device 32 can connect the second walls of two different structural forms (eg, the second wall 20b and the other second wall 200) to the first wall 20a without relying on accessories, so as to satisfy the market demand different needs.

According to the above description, it can be seen that the enhancement effect and advantage of the present invention are:

a. Provide a tool-free way to connect the second wall 20b of the furniture 20 to the first wall 20a, and the assembly and disassembly are convenient and easy.

b. The at least one latching arm 36 is substantially laterally disposed relative to the longitudinally disposed first wall 20a, and the installation direction Y of the second wall 20b is substantially parallel to the at least one latching arm 36 disposed in the lateral direction, This helps the user to connect the second wall 20b to the first wall 20a.

c. Without additional accessories, the connecting device 32 can connect the second wall (20b, 200, this part can refer to FIG. 3 or FIG. 15 ) with two different structural forms to the first wall 20a, so as to meet different market requirements demand.

Although the present invention has been described with reference to the present specific embodiments, those of ordinary skill in the art will recognize that the above embodiments are only used to illustrate the present invention, and can be made without departing from the spirit of the present invention Various equivalent changes and modifications, therefore, as long as the changes and modifications to the above-mentioned embodiments within the essential spirit of the present invention, will fall within the scope of the claims of the present application.
