As shown in FIGS. 1 to 3, the sliding door interlocking device of the present invention is installed at the entrance of a house, building, warehouse, storage, etc., and is provided with three or more sliding doors 1, 2 and 3 that can be opened and closed freely. By sliding the racks 10, 11, 12, 13 and the plurality of pinions 21, 22, the sliding doors 1, 2, 3 can be opened / closed in an interlocking manner while being differentially operated.

  1 to 3, the first sliding door 1, the second sliding door 2, and the third sliding door 3 are provided so as to be openable and closable, and the fixed rack 10 is attached to the fixed frame F, and the first sliding door The first movable rack 11 is attached to 1, the second movable rack 12 is attached to the second sliding door 2, and the third movable rack 13 is attached to the third sliding door 3. A first pinion 21 is attached to the first sliding door 1, and a second pinion 22 is attached to the second sliding door 2. Then, the first pinion 21 is engaged with the fixed rack 10 and the second movable rack 12, and the second pinion 22 is engaged with the first movable rack 11 and the third movable rack 13, so that the first sliding door 1 and the second sliding door are engaged. The second sliding door 3 and the third sliding door 3 are configured to open and close in conjunction with each other while being differentially operated.

The fixed rack 10, the first movable rack 11, the second movable rack 12, and the third movable rack 13 are made of prismatic metal or hard resin, and gear teeth are formed on one surface. In a plan view, the fixed rack 10 is attached to the side of the fixed frame F that faces the first sliding door 1, and is disposed so as to protrude from the front end of the fixed frame F. The first movable rack 11 is attached to the side of the first sliding door 1 facing the second sliding door 2, and is disposed so as to protrude from the front end of the first sliding door 1. The second movable rack 12 is arranged in parallel on the side of the second sliding door 2 facing the first sliding door 1. The third movable rack 13 is arranged in parallel on the side of the third sliding door 3 facing the second sliding door 2.
The first pinion 21 includes a spur gear and is rotatably attached to the upper surface of the front end portion of the first sliding door 1. In the fully opened state of FIG. 1, the first pinion 21 meshes with the rear end portion of the fixed rack 10, and meshes with the front end portion of the second movable rack 12 on the opposite side.
The second pinion 22 includes a spur gear and is rotatably attached to the upper surface of the front end portion of the second sliding door 2. In the fully opened state of FIG. 1, the second pinion 22 meshes with the rear end portion of the first movable rack 11 and meshes with the front end portion of the third movable rack 13 on the opposite side.
The number of teeth of the first pinion 21 and the second pinion 22 is the same, and the pitch of the gear teeth of the first moving rack 11, the second moving rack 12, and the third moving rack 13 is the same.

The first movable rack 11, the second movable rack 12, the third movable rack 13, the first sliding door 1, the second sliding door 2, and the third sliding door 3 are formed to have substantially the same length in plan view. its size is slightly larger than the 1/3 times the width W ₀ of the doorway. That is, in the fully opened state of FIG. 1, a large opening amount (entrance width W ₀ ) that is about three times the width of the fixed frame F is secured, and the first sliding door 1, the second sliding door 2, and the third sliding door 3 are secured. It can be accommodated in a door pocket 4 having about 1/3 the depth of the width W ₀ of the doorway. Moreover, as shown in FIG. 3, the 1st sliding door 1, the 2nd sliding door 2, and the 3rd sliding door 3 are pulled out from the door pocket 4, and it is made into a closed state, and the vast doorway can be closed. A handwheel handle 6 is attached in the vicinity of the front end of the third sliding door 3, and a cushion member 18 is provided at the front end edge of the third sliding door 3 for reducing the impact with the door stop. .

As shown in FIG. 4, three guide rails 40, 40, 40 are fixed to a vertical surface of a support frame (upper frame) 50 formed in a step shape, and can freely slide on the guide rails 40, 40, 40. The first sliding door 1, the second sliding door 2, and the third sliding door 3 are suspended by the suspension vehicles 41, 41, 41.
The first pinion 21 and the second pinion 22 are arranged to be shifted in the vertical direction with a predetermined height difference. In other words, the height position at which the first pinion 21 meshes with the fixed rack 10 and the second movable rack 12 and the height position at which the second pinion 22 meshes with the first movable rack 11 and the third movable rack 13 are: Different from each other, with this configuration, the first moving rack 11 and the second moving rack 12 move without colliding with each other.

The use method (action) of the above-described sliding door interlocking device of the present invention will be described.
When the third sliding door 3 is pulled out and moved as indicated by arrow C from the fully open state of FIG. 1 to the half-opened and semi-closed state of FIG. 2, the second pinion 22 meshing with the third movable rack 13 is counterclockwise. Rotate. The second pinion 22 rolls on the first moving rack 11, and the second sliding door 2 moves while being differentially delayed from the third sliding door 3.
As the second sliding door 2 moves, the first pinion 21 that meshes with the second movable rack 12 rotates counterclockwise. The first pinion 21 rolls on the fixed rack 10, and the first sliding door 1 moves while being differentially delayed from the second sliding door 2.
Regarding the relationship between the first sliding door 1 and the second sliding door 2, the ratio of the movement amount (running allowance) dimension L ₁ of the first sliding door ₁ and the movement amount dimension L ₂ of the second sliding door 2 is 1: 2.

Moreover, about the relationship between the 2nd sliding door 2 and the 3rd sliding door 3, when it assumes that the 1st sliding door 1 does not move, the ratio of the movement amount will be 1: 2. However, the first moving rack 11 moves together with the first sliding door 1, calculated on the amount of movement of the second sliding door 2 and the third sliding door 3 in consideration of the influence of the amount of movement dimension L ₁ of the first sliding door 1, the a moving amount dimension _{L 2} of 2 sliding doors 2, the ratio of the amount of movement dimension _{L 3} of the third sliding door 3 is 2: 3.
That is, the moving distance dimension L ₁ of the first sliding door 1, the amount of movement dimension L ₂ of the second sliding door 2, the ratio of the amount of movement dimension L ₃ of the third sliding door 3 becomes 1: 2: 3. In other words, the second sliding door 2 moves at a speed 2/3 times the moving speed of the third sliding door 3, and the first sliding door 1 moves at a speed 1/3 times.

In this way, the first pinion 21 of the first sliding door 1 is engaged with the fixed rack 10 and the second movable rack 12, and the second pinion 22 of the second sliding door 2 is engaged with the first movable rack 11 and the third movable rack 13.
