Description

[Detailed explanation of the idea] 【Technical field】

The present invention relates to a floor contacting device for a partition door that moves left and right along a rail.

[Background technology]

Conventionally, the structure was such that the flooring member was raised and lowered by operating a lever installed at the top of the partition door, so when moving the partition door, the flooring member was moved by manually operating the lever. was pulled up, and when the partition door was to be stopped, a lever was manually operated to press the floor contact member against the floor.
Therefore, it takes time and effort to raise and lower the floor contacting member.

[Purpose of invention]

The present invention was developed in view of the above-mentioned technical background, and its purpose is to automatically insert and remove the floor contact member.

[Disclosure of invention]

The movable partition door flooring device of the present invention is provided with arms 2 on both sides of the lower part of the door body 1 that are vertically slidable and swingable with the upper end as a fulcrum.
Both ends of the floor-contacting member 3 are rotatably attached to the lower end, the arm 2 is urged downward by elastic force, and a spring 4 is stretched between the arm 2 and the arm support 7 to form the arm. 2 in both flip-up directions, and restrict the rotation range of the arm 2 so that it is large on one side and small on the other side in the vertical state, and in the state of large rotation, the end of the floor contact member 3 touches the door body. It is characterized by being formed so as to protrude from the side end of 1. Thus, when the arm 2 rotates significantly and the floor contacting member 3 is flipped up, the door body 1 moves freely. Then, when the door body 1 is closed and the protruding end of the floor contact member 3 is pushed and retracted, the arm 2 is reversed and moved to the small rotation side,
Since the arm 2 is elastically biased downward, the floor contacting member 3 is brought into elastic contact with the floor. Conversely, when the door body 1 is moved in the opening direction, the floor contact member 3 tends to remain due to friction, so the arm 2 is reversed and moves to the side with a large rotation angle, and the floor contact member 3 is flipped up. . Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. As shown in FIG. 3, the partition door has a door body 1 suspended from an upper rail 6 by a runner 5 so as to be freely movable, and a floor contacting device is built in the lower part of the door body 1. The floor contacting device has a structure as shown in FIGS. 1 and 2, and a slider 9 having a substantially U-shaped cross section is installed in a rail body 8 having a U-shaped cross section so as to be able to move up and down. Vertical long hole 1 drilled in
The bar 11 of the rail body 8 is inserted through the bar 11 of the rail body 8, so that the slider 9 can slide up and down only within the length of the elongated hole 10. and bar 11 of rail body 8
A tension spring 14 is tensioned between the slider 9
is elastically biased downward. The upper end of an arm 2 is rotatably attached to the lower end of the slider 9 so that the arm 2 can slide up and down together with the slider 9. The lower ends of both arms 2 have a U-shaped cross section. Both ends of the floor contacting member 3 are rotatably secured by pins 12. Arm support part 7
A lower bar 15 provided at the bottom of the slider 9
A spring 4 is tensioned between the arm 2 and the pin 12 of the arm 2, and the arm 2 is biased in the direction of being flipped up. In addition, when the arm 2 is vertical, the pivot point at the upper end of the arm 2, the lower bar 15 holding the spring 4, and the pin 12 are aligned in a straight line, so that the arm 2 becomes vertical as shown in FIG. 2 can rotate at a large angle in the direction of closing the door body 1, but can only rotate at a small angle in the direction of opening the door body 1, as shown in FIG.
For example, the arm 2 may be brought into contact with the lower end of the rail body 8 and stopped in the state shown in FIG. 2. Further, on the side of the large rotation angle, the floor contact member 3 is raised from the floor, and the end portion of the floor contact member 3 protrudes from the side end surface of the door body 1. On the other hand, on the side where the rotation angle is small, the floor-contacting member 3 contacts the floor and is brought into elastic contact with the floor by the elastic force of the tension spring 14. When the door body 1 is moved in the closing direction A as shown in FIG. When it hits the end surface, the floor contacting member 3 is pushed. When the floor contact member 3 is pushed, the arm 2 rotates and the floor contact member 3 is brought into elastic contact with the floor, and the arm 2 is pressed against the spring 4.
After passing the dead center of , the floor-contacting member 3 is kept in elastic contact with the floor as shown in FIG. Conversely, when the door body 1 is moved in the opening direction B, the floor contact member 3 is in elastic contact with the floor and tends to remain behind, so the arm 2
is rotated, and the floor-contacting member 3 is flipped upward as shown in FIG. 1, and the floor-contacting state is automatically released. 4 and 5 are other examples of the present invention, in which a long hole 16 is bored in the upper end of the arm 2, and a bar 11 of a rail body 8 having a U-shaped cross section.
is inserted into the elongated hole 16 of the arm 2, so that the arm 2 can slide up and down along the elongated hole 16, and the upper end of the arm 2 and the lower part of the rail body 8, which is the arm support part 7, A spring 4 is tensioned between them, and the elastic force of the spring 4 urges the arm 2 downward and in the upward direction. What is shown in FIG. 6 is yet another example of the present invention,
Although the structure is similar to the first embodiment, the lower end of the arm 2 is slidably connected to a long hole 17 bored in the flooring member 3, and a permanent magnet 18 is attached to the closing side end of the flooring member 3. It is provided. By making the permanent magnet 18 stick to an iron piece such as a wall when closing, the closed state of the door body 1 is maintained, and when the door body 1 is closed, the permanent magnet 18 is attached to a piece of iron such as a wall. By adhering to the iron piece, the floor contacting member 3 is pulled back, and the state of contact with the floor can be reliably released.

[Effect of the idea]

The present invention is constructed as described above, so when the partition door is closed, the floor contacting member is pushed sideways, and by reversing the arm, the flooring member is automatically pushed down and brought into pressure contact with the floor. When the partition door is opened, the arm is reversed as the floor contact member tries to remain due to friction with the floor, and the floor contact member is pulled up and automatically released from the floor contact state.

Claims (1)

[Scope of utility model registration request] An arm is provided on both sides of the lower part of the door body that can freely slide vertically and swing freely using the upper end as a fulcrum, and both ends of the floor contacting member are rotatably attached to the lower end of both arms. The arm is biased downward, and a spring is placed between the arm and the arm support to bias the arm in both flip-up directions, making the rotation range of the arm greater in one vertical position and smaller in the other. This flooring device for a movable partition door is configured such that the position of the movable partition door is regulated in such a manner that the end of the flooring member protrudes from the side end of the door body when the flooring member is rotated significantly.
