The mounting bracket 4 includes an L-shaped door plate mounting plate 41 fixed to the rear surfaces of the door plates A and B, a support plate 42 for rotatably supporting the rotating shaft of the traveling body 22 at right angles, and a rail 21. Mouth mechanism The lock mechanism operation plate 43, which has penetrated the groove 21 for the lid, is formed. The traveling body 22 has two sets of two orthogonal rotation axes, and two sets are provided for each of the door plates A and B, and a box-shaped guideway 2 1 1 of the rail 21 is provided. Guided to 4 opposing sides of 2 1 2. Therefore, the traveling body 22 smoothly travels on the proposed roads 2 1 1 and 2 1 2 of the rail 21 without rattling.

The slide assist mechanism 3 assists the sliding operation of the door plates A and B, and includes a mounting bracket 31, a wire 32, a fixed pulley 33, a weight 34, and a moving pulley 35. The mounting bracket 31 is fixed to the upper end of the mounting substrate 1 and rotatably supports the fixed pulley 33. The wire 32 consists of one common terminal whose terminals are fixed to the door plates A and B (of the mounting plate 41 of the mounting bracket 4) and are hung on the fixed pulley 33 and the moving pulley 35.

When the rail 21 rotates rearward, the rail 21 is linear. The guideway 2 1 1 on the rear side of the rail 2 1, which has been turned when it is turned forward, is communicated with the guideway 2 1 2 on the front side of the rail 2 1 that is not turned. The The cushioning material 53 attenuates the impact sound of the abutment of the locking piece 52 against the abutment plates 54, 55 to prevent abrasion due to the impact.

Further, in the first example, a turning position holding mechanism 6 that holds the turning position of the rail 21 of the slide guide mechanism 2 is provided.

The rotation position holding mechanism 6 includes a blade plate 61 attached near the rotation tip of the rail 21 of the slide guide mechanism 2, a blade plate 61 and a stopper piece 5 of the rotation range regulating mechanism 5. 1 and a torsion-coin spring 6 2. The torsion coil spring 62 is displaced in response to the rotation of the rail 21 of the slide guide mechanism 2 and elastically retains the front and rear rotation positions.

Further, in the first example, a lock mechanism 7 that locks the rotation position of the rail 21 of the slide guide mechanism 2 is provided.

As shown in detail in FIG. 13, the lock mechanism 7 is slidably housed in the lock mechanism slide groove 2 13 of the rail 21 of the slide draft mechanism 2 and the rail 2. A slide block 71 located near the rotating end of the shaft 1, a shaft 7 2 connected to the slide block 71 and disposed inside the lock mechanism slide groove 2 13, The U-shaped guide 73, which is fixed in the slide mechanism groove 2 13 and supports the shaft 72 at two points in the longitudinal direction, and the slide block 71 of the shaft 72 The operation block 74 of the angle block is fixed to the opposite end and is slidably accommodated in the lock mechanism slide groove 2 13, and the slide block 7 1 and the guide 7 3 A coil spring that is interposed between them and urges the slide block 71 toward the tip of the rail 21 That Do not because the 7 5. The operation block 74 is locked to the opening mechanism operation plate 43 of the mounting bracket 4 mounted on the door plates A and B against the resilience of the coil spring 75, and is locked when the door plates A and B are opened and closed. The slide of the slide block 7.1 is protruded from the rotating end of the rail 21 by the elastic pressure of the coil spring 75 acting on the slide of the mechanism operation plate 43. The protruding slide block 7 1 is a guide for the front side of the groove 2 1 4 for the force-par mechanism slide rail 21. Locked near the road 2 1 2 to lock the rotation position of the rail 2 1. Note that the protrusion limit of the slide block 71 is determined by the contact between the guide 73 and the operation block 74 near the operation block 74. Therefore, the slide block 71 does not protrude more than necessary. Further, in the first example, a cover mechanism 8 for closing the opening and closing gaps of the door plates A and B is provided.

As shown in detail in FIGS. 4 and 11, the cover mechanism 8 is slidably housed in the slide groove 2 14 of the force-par mechanism on the rail 21 of the slide guide mechanism 2. A pair of upper and lower sliders 81, a regulating plate 82 connected to the side of the slider 81 and regulating the slide area with a long hole, and a cover plate connected to the front of the slider 81 8 3, a wire 84 connected to the slider 81 located on the rotation base end side of the rail 21, a support plate 85 attached to the rotation base end of the rail 21, and a rail 21. The coil spring 86, which is hung between the slider 81 and the support plate 85 located at the rotation end side, and the end of the wire 84 attached to the contact piece 11 of the mounting substrate 1 It comprises a linked link portion 87 and a hook 88 attached to the rail 21 and locked to the link portion 87. The link portion 87 is raised by the hook 88 as the rail 21 rotates forward, and the wire 84 is extended. The extension of the wire 84 brings the slide of the cover plate 83 to eliminate the opening / closing gap of the door plates A and B.

Further, in the first example, a closing and holding mechanism 9 for holding the doors A and B in a closed state is provided.

The closing and holding mechanism 9 includes a roller 91 attached to the upright piece 12 of the mounting board 1 and abutting against the mounting bracket 4, and a cushioning material 92 mounted to the mounting bracket 4.

According to the first example, as shown in simplified form in FIGS. 1 and 2, the doors Α,... B are pulled forward and then raised or lowered to open and close. When doors A and B are pulled forward, the slide guide mechanism 2 rails 2 1 Is pivoted to communicate with the front guideway 2 11 1 of the rails 21 on the door plates A and B side where the rear guideway 2 11 is not pulled. This communication is precisely performed by the rotation range regulating mechanism 5. Therefore, the traveling body 22 smoothly travels while slightly changing the direction of the guide paths 2 11 1 and 2 12 of the rail 21. The rollers 91 of the closing and holding mechanism 9 roll and guide the movement of the mounting bracket 4 accompanying the opening and closing of the door plates A and B.

When the door plates A and B are pulled forward, the rotation position holding mechanism 6 and the lock mechanism 7 prevent the slide guide mechanism 2 from rotating rearward on the rail 21. The traveling body 22 reliably travels while slightly changing the direction of the guideways 2 1 1 and 2 1 2 of the rail 21. Also, the cover mechanism 8 closes the opening and closing gap between the door plates A and B, so that the finger may not be pinched too much. That is, the rotating structure of the rail 21 of the slide guide mechanism 2 replaces the configuration of the rail 21 of the conventional technology. Therefore, the doors A and B can be smoothly opened and closed even though the structure of the slide guide mechanism 2 is simple.

In the first example, when the door plates A and B rise, the weight 34 of the slide assist mechanism 3 exerts an assisting force, and when the door plates A and B descend, the slide assist mechanism 3 Weights 3 4 provide resistance. Therefore, the sliding operation does not become heavy due to the heavy load applied to the door plates A and B, and the door plates A and B do not drop rapidly, and the door plates A and B arranged in the vertical direction can be stably moved. Can be operated.

FIG. 15 shows a second example of the best mode for carrying out the present invention.

In the second example, the guide paths 2 1 1 and 2 1 2 of the rails 21 of the slide guide mechanism 2 are formed as projections on both sides of the plate shape, and are of a simple type.

FIG. 16 shows a third example of the best mode for carrying out the present invention.

. In this third example, door plates A and B are arranged in the horizontal direction.

FIG. 17 shows a fourth example of the best mode for carrying out the present invention. It is.

In the fourth example, the door plates A and B are made into one sheet, and are overlapped on the blind plate C provided with the groove S through which the upper mounting bracket 4 passes. The rail 21 of the slide guide mechanism 2 on the side of the blind plate C is not configured to be rotatable.
