(Example)

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is a view showing a sliding structure according to the present invention, in the movable member 30 consisting of a first member 10 and a second member 20 which is relatively sliding relative to the first member 10. , The proximity and separation operation between the first member and the second member is shown.

Here, the first member 10 includes moving path forming parts 11a and 11b which are horizontal plates on which moving paths defining the moving direction of the second member 20 are formed. In addition, the second member 20 includes rail forming parts 21a and 21b which are horizontal plates on which rails moving along the moving path forming parts 11a and 11b are formed.

Meanwhile, the movement path forming parts 11a and 11b formed in the first member 10 may include an upper movement path forming part 11a and a lower movement path forming part 11b in which a channel-shaped movement path 11c is formed. The upper and lower movement path forming portions 11a and 11b are provided in parallel and are spaced apart by maintaining a predetermined distance d by the connecting portion 12.

In addition, the rail forming portions 21a and 21b formed on the second member 20 may be formed in a corresponding shape of the channel cross section which may be inserted into and move in the channel 11 of the movement path 11c and the upper rail forming portion 21a. ) And the lower rail forming portion 21b, and the upper and lower rail forming portions 21a and 21b are provided in parallel and are spaced apart by maintaining a predetermined distance d 'by the connecting portion 22. Accordingly, the first member and the second member have a substantially "⊂" shape facing each other.

As the rail forming parts 21a and 21b move along the moving path forming parts 11a and 11b, that is, as the rail moves along the moving path, the first member and the second member are spaced apart or close to each other. .

In addition, one end of the lower movement path forming portion 11b of the first member 10 (an end not facing the second member) is capable of shaft rotation with an additional member (for example, a frame member described below). An annular portion 13 for coupling is formed, and an additional member (for example, a frame member) is formed at one end of the upper rail forming portion 21a of the second member 20 (an end not facing the first member). A ring portion 23 for axially rotatable coupling with) is formed.

Accordingly, the ring portions 13 and 23 are positioned in a diagonal direction with the parallel moving path and the rail forming portions 11 and 21 interposed therebetween. This is a structure for facilitating shaft rotation of the first member and the second member by biasing the center of gravity.

On the other hand, the other end of the first member 10 is provided with a guide connecting portion 24 to be movable across the upper movement path forming portion (11a) and the lower movement path forming portion (11b). That is, it is hypothesized so that the connection part 24 may move along the guide 11d formed in predetermined length in the part which opposes the upper and lower movement path forming parts 11a and 11b. Here, the amount of movement on the guide 11d of the connecting portion 24 is determined according to the length of the guide 11d. In addition, the length of the guide 11d is formed shorter than the length of the moving path (11c).

On the other hand, the guide rod 24a is formed to protrude in both directions in the guide connecting portion 24, and the guide rod 24a is used for inserting the guide rods formed in the connecting portions 12 and 22 of the first member and the second member. Is inserted into and passed through the openings 12a and 22a.

Therefore, the guide connecting portion 24 is provided on the guide rod 24a protruding in both directions from the opposing side surfaces and the portions of the moving path forming portions 11a and 11b facing each other on the side surfaces other than the opposing side surfaces. It becomes a single piece provided with both ends 24b which are rails which move along the formed guide 11d. As an example, the guide 11d is formed of a flat protrusion, and both ends 24b are formed in a groove shape in which protrusions are accommodated.

On the other hand, in the present embodiment, three guide rods 24a are shown, but the number can be changed in various ways in connection with the rigidity of the sliding structure.

In addition, the other end of the rail forming portion (21a, 21b) of the second member 20 (the end facing the first member) that the rail forming portion (21a, 21b) is out of the moving path (11c) A first stopper member 25 for preventing is provided. For example, the first stopper member may be formed by processing the tips of the rail forming parts 21a and 21b to form a ring in the form of an arrowhead or a hook. Accordingly, the second stopper member 15, which is a blocking member that prevents the first stopper member 25 from being separated, may be provided at an end portion of the movement path 11c of the first member 10. In addition, in FIG. 1, the 1st and 2nd stopper member was shown large in order to make understanding easy.

Accordingly, the guide rod 24a is inserted into the openings 12a and 22a with both ends 24b of the guide connecting portion 24 inserted into the guide 11d, and then the first stopper member 25 is When the rail forming portions 21a and 21b formed at the front end are forcibly inserted into the movement path forming portions 11a and 11b in which the second stopper member 15 is formed, the first member and the second member are prevented from moving away. The member 30 is formed.

In addition, in FIG. 1, the code | symbol 21c shows the step part or flange 21c from which the main part differs in height from the said rail formation part 21a, 21b. Therefore, it can be seen that the cross-sectional shapes of the moving path forming parts 11a and 11b may also be variously changed according to the shape of the rail forming part 21.

Here, (a) of FIG. 1 shows a state in which the first member and the second member are spaced apart, and FIG. 1 (b) shows a close state. In the spaced state of FIG. 24 is located at the other end of the 1st member which opposes a 2nd member adjacently on the guide 11d formed in the mutually opposing part of the upper and lower movement path formation parts 11a, 11b, and guide rod 24a. The tip of) is inserted into the opening in the vicinity of the openings 12a and 22a for insertion.
