Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a sliding door opening / closing structure capable of opening and rotating a door body so as to be substantially orthogonal to upper and lower rails,
More specifically, the present invention relates to a technique for reliably performing steady rest of the door body that has been opened and rotated so as to be substantially orthogonal to the upper and lower rails.

[Prior Art] Conventionally, a door main body is configured to be freely movable along an up-down running tool along an upper rail having a substantially inverted U-shaped cross-section that is open at the bottom and a lower rail that is open at the top. In the opening / closing structure of the sliding door which is opened and pivoted so as to be substantially orthogonal to the upper and lower rails via the vertical traveling tool, the door body is not held at the opening pivot position.

[Problems to be solved by the invention] Then, the door body that is opened and rotated so as to be substantially orthogonal to the upper and lower rails swings at the opened and rotated position,
There is a problem in that the opening and rotating position is not stable, the adjacent door bodies are rubbed, and the surfaces of the door bodies are scratched.

The present invention has been made in view of the above problems, and an object of the present invention is to reliably hold the open and rotated position of the door body that has been opened and rotated, and to eliminate the swinging of the door body. The main bodies do not rub against each other and are not scratched, and in addition, this kind of operation can be performed without failure.For other purposes, the opening and rotation of the door main body is reduced with resistance to the floor. An object of the present invention is to provide an opening / closing structure of a sliding door that can open and rotate the door body.

[Means for Solving the Problems] In the sliding door opening / closing structure of the present invention, a slender shaped held portion 6 is formed on the up / down running tools 3a, 3b, and the door body 2 is opened / closed at the open / close position. Vertical running gear 3a on rails 1 and 8
A narrow portion a of 3b that passes through the held portion 6 and a wide portion b that prevents the steadying of the door main body 2 that has been opened and rotated by pressing both ends in the length direction of the held portion 6 are formed. The narrow portion a is constituted by the spring plate 20, and the elastic body c of the cushion material is arranged on the back portion of the spring plate 20.

In addition, the holding portion 6 is formed on the rail 8 along with the opening and rotation of the door body 2 to form a lifting portion d for lifting the door body 2.

[Operation] As described above, the held portion 6 is formed on the vertical traveling tools 3a, 3b, and the vertical rails 1, 8 at the open / rotated position where the door body 2 is opened and rotated is covered by the vertical traveling tools 3a, 3b. By forming a narrow portion a through which the holding portion 6 passes and a wide portion b that presses both ends of the held portion 6 and presses and swings to open and swing the door body 2, the door body 2 is opened and closed. In the moving position, the held portion 6 provided integrally with the door body 2 also rotates integrally with the door body 2, and both ends of the held portion 6 are pressed against the wide portion b in a tension bar shape, so that the door body 2 The door main body 2 can be held without swinging in the open / closed position of the door, and such holding is performed by the wide portion b provided on the upper and lower rails 1 and 8 and the vertical traveling tools 3a and 3b.
And the held portion 6 formed on the door main body 2
The steady rest can be reliably performed, and the narrow portion a
Is formed of a spring plate 20, and an elastic body c of a cushion material is arranged on the back portion of the spring plate 20. The elastic body c of the cushion material on the back of the spring plate 20 can further enhance the cushioning property, and the permanent deformation of the spring plate 20 can be prevented.

Further, since the held portion 6 rides on the lower rail 8 as the door body 2 is opened and rotated to lift the door body 2, the held portion 6 is lifted when the door body 2 is opened and rotated. The door main body 2 is lifted by riding on the lifting portion d to reduce the resistance between the door main body 2 and the floor.
It is designed so that the opening and rotating of the can be performed lightly.

It is configured so that it can travel freely via. Specifically, a disc-shaped upper traveling tool 3a is integrally attached to the door body 2 through the mounting shaft 10 at the upper end of the door main body 2 on the door tip side. 3a is mounted on the mounting surface 11 of the upper rail 1.
A sub-runner 15 is rotatably attached to the rear upper end of the door body 2 via a runner shaft 14, and the sub-runner 15 is mounted on the mounting surface 11 of the upper rail 1 so that the door body 1 is mounted on the upper rail 1. It is suspended so that it can run freely.

In the lower part of the door body 2, a floor contacting member 16 is provided so as to be vertically movable over substantially the entire length of the door body 2. A lower shaft 13 provided with a slider 12 as a lower traveling tool 3b is provided at the lower end of the door body 2 of the door body 2 downwardly by a spring 23 to urge the slider 12 to a lower rail 8. It is slidably inserted. And floor contact member 16
A slider 17 is provided so as to project from the rear lower end of the slider, and the slider 17 is slidably inserted in the lower rail 8. Floor contact member 16
Is operated by the operation knob 19, and the raised position is releasably locked so that the floor contact member 16 moves the slider 17
The lower rail 8 is in a slanted position so that the side floats greatly.
It is designed so that it can be held in a state of being lifted up from (see Fig. 1).

The door main body 2 has upper and lower rails at its traveling end.
It is designed so that it can be rotated substantially open with respect to 1,1,8,8. The opening and rotating structure of the door body 2 will be described in detail below.

A narrow portion a and a wide portion b as shown in FIGS. 5 to 7 are provided on the upper and lower rails 1 and 8 at the traveling end position of the door main body 2, that is, at the open rotation position where the door main body 2 is opened and rotated. Spring leaf 20
The channel member 22 formed by the above is inserted. A narrow portion a is provided on the upper surface of the disk-shaped upper traveling tool 3a fixed to the door body 2.
A rod-shaped held portion 6 is formed which can pass through and enter the wide portion b. The slider 12 inserted into the lower rail 8 is also formed in a substantially rod shape, and the slider 12 itself holds the held portion 6.
Is shaped. Further, both ends of the upper and lower held portions 6 are pressed against the wide portions b of the upper and lower rails 1 and 8 in the form of tension rods so that the door body 2 rotated and opened can be prevented from swinging up and down.

[Advantages of the Invention] In summary, according to the present invention, the vertical traveling tool is formed with an elongated held portion, and the held portion of the vertical traveling tool passes through the vertical rail portion at the open pivot position where the door body is opened and rotated. Since the narrow portion and the held portion at both ends in the length direction are pressed into contact to form a wide portion that prevents the swinging of the door body that has been opened and rotated, at the opened and rotated position of the door body, The held part provided integrally with the door main body also rotates together with the door main body, and both ends of the held part are pressed against the wide part in the form of tension rods to swing the door main body at the open and open position of the door main body. It can be held without causing it, and such holding is performed by the wide portion provided on the upper and lower rail sides and the held portion formed on the vertical traveling tool, and it is possible to reliably perform steady rest of the door body. The narrow part is composed of a spring plate, and the back part of the spring plate is clamped. Since the elastic body of the cushioning material is arranged, the slipperiness of the narrow plate can be improved by the spring plate constituting the elastic body, and the elastic body of the cushion material on the back part of the spring plate is more effective. It is possible to obtain the cushioning property and to prevent permanent deformation of the spring plate.

In addition, since the held portion is formed on the lower rail as the door body is opened and rotated to lift the door body, the held portion rides on the lifted portion when the door body is opened and rotated. There are advantages that the main body is lifted, resistance to the floor is reduced, and the door main body can be opened and rotated lightly.
