Description

[Detailed description of the invention] [Industrial application field] The present invention is applicable to sliding or rotating doors.
The upper surface of the door and members such as stile members or ceilings for the upper surface (hereinafter simply referred to as "stiles, etc.")
This invention relates to an improvement in a sealing device that closes the gap between the bottom surface of the door and a member such as a floor or threshold member for the bottom surface (hereinafter simply referred to as "floor, etc."). .

[Conventional technology]

A longitudinal sealing base is disposed at least at the lower end or upper end of the sliding or rotating door so as to be movable up and down along the frontage direction of the door, and an actuating body is placed between the sealing base and the door. The actuating body is slidably mounted in the frontage direction, and the actuating body and the sealing base are interlocked and connected so that the sealing base moves up and down as the actuating body slides, and , a return spring is provided that urges the sealing base in a direction toward the door, and a protrusion integrally formed at one end of the operating body protrudes from one side of the door, and this protrusion is used to close the door. When closed, by sliding the actuating body backward in contact with a member such as a pillar, the sealing base is pressed against the door stile, etc., or the floor, etc., thereby closing the gap between it and the stile, etc. or floor, etc. A door sealing device that closes the door has been proposed as prior art, such as in Japanese Utility Model Application Publication No. 54-82439.

[Problem that the invention attempts to solve]

This type of door sealing device requires that the sealing base be in close contact with the stile or the floor when the door is completely closed.
The sealing device of the prior art has a structure in which a protruding body is integrally formed at one end of the operating body to make the operating body slide backward by coming into contact with a member such as a pillar when the door is closed. However, since there is no adjustment means between the backward sliding distance of the protruding body and the actuating body and the rising or falling distance of the sealing base when the door is closed, the door, stile, etc. or floor If the gap between the door and the stile or the floor is large, the sealing base will not come into close contact with the stile or the floor when the door is completely closed, and the gap between the door and the stile or the floor, etc. If the door is small, the sealing base gets stuck on the stile or the floor before the door is completely closed, resulting in a problem that the door cannot be closed completely.

The present invention solves this problem.

[Means to solve the problem]

For this reason, the present invention provides a sliding or rotating door with a longitudinal sealing base that is movable up and down at least on the lower or upper surface along the frontage direction of the door, and a space between the sealing base and the door. an actuating body is slidably mounted in the direction of the frontage of the door, the actuating body and the sealing base are interlocked and connected so that the sealing base moves up and down as the actuating body slides; In a door sealing device that is provided with a return spring that urges the sealing base in a direction toward the door, the door has a protruding body arranged in the same direction as the sliding direction of the actuating body. A spring is provided between the protruding body and the actuating body, the spring being larger than the return spring and biasing the protruding body so that one end of the protruding body protrudes from one side of the door. This configuration includes an adjustment spring with force.

[Functions and effects of the idea]

With this configuration, when the door is opened, the protruding body protrudes from one side of the door by the adjustment spring, and when the door is closed, it comes into contact with a member such as a pillar and slides backward. This backward movement is transmitted to the actuating body via the adjustment spring, causing the actuating body to slide backward, but since the spring force in the adjustment spring is greater than the spring force of the return spring against the sealing base, As the operating body slides backward, the sealing base moves upward or downward away from the door against the return spring, and comes into close contact with the stile or the floor.

In this sealed state, the sealing base is pressed against the stile, floor, etc. by the spring force of the adjustment spring provided between the protruding body and the operating body, so that the door can be sealed more reliably. It is.

Moreover, since the protruding body can still move backward against the adjustment spring provided between it and the actuating body, the protruding body and the actuating body can move backward when the door is closed. By setting the rise or fall distance of the sealing base relative to the distance according to the case where the gap between the door and the stile or floor is large, the gap between the door and the stile or the floor can be reduced. If the protrusion is small, the protrusion will move backward against the adjustment spring provided between the protrusion and the actuating body, thereby preventing the door from being unable to be completely closed. It can be done.

Therefore, according to the present invention, even if there is a gap between the door and the stile or the floor, etc., the gap can be reliably sealed when the door is closed.
This has the effect of preventing the door from being unable to close completely.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. In the drawings, 1 indicates a plurality of partition doors, 2
3 indicates the floor surface, 3 indicates the side wall, 4 indicates the ceiling surface, and 5 indicates a box-shaped cross-section guide rail installed on the ceiling surface. By inserting a flexible roller 6 into the guide rail 5, it is configured to move freely along the guide rail 1.

A sealing device 7 as described below is provided on the upper and lower surfaces of each door 1, respectively.

That is, a frame 8 having a downward U-shaped cross section is provided on the lower surface of the door 1 along the frontage direction of the door, and the sealing device 7 for the lower surface of the door 1 is
An actuating body 9 having a downward U-shaped cross section and sliding freely back and forth in the longitudinal direction along the ceiling surface within the frame body 8.
and a sealing base 10 disposed vertically movably within the frame 8.

For example, in the embodiment shown in FIG. 2, each of the partition doors 1 is assumed to move forward in the direction of arrow A, and the top plate of the operating body 9 is provided with long slot holes 11 in at least two places. Bolt 1 passing through long slot hole 11
2 to the top plate of the frame body 8, the actuating body 9 is supported slidably in the longitudinal direction by a pair of upper and lower slider shoes 13 that are fitted onto each of the bolts 12.

An inclined guide surface 14 is formed at one end of the actuating body 9 by fixing a plate member 14' that slopes downward in the forward direction of the door 1. , a protruding body 15 is provided to freely slide in the same direction as the sliding direction of the actuating body 9, and the protruding body 15 is fixed to the door 1 by an adjustment spring 16 provided between the protruding body 15 and the actuating body 9. It is biased so that it protrudes by an appropriate amount from the notch 18 on one side of the.

On the other hand, the actuating body 9 is attached to the sealing base 10.
It has an upwardly U-shaped cross section with a pair of left and right curtain plates 19 that fit into the sealing base 10, and has two sealing members 20 extending in the longitudinal direction on its lower surface. A sliding body 21' such as a synthetic resin slider that comes into contact with the inclined guide surface 14 of the actuating body 9 is fixed, and the reference numeral 14'' in the figure is
An auxiliary inclined guide surface provided at the other end of the operating body 9, and a sealing base 10 on the auxiliary inclined guide surface 14''.
A roller-shaped sliding body 21'' attached to the holder comes into contact with the holder.

Then, between the operating body 9 and the sealing base 10, both the sliding bodies 21' and 21'' are arranged on the inclined guide surface 1.
4, 14'', and a return spring 23 for urging the sealing base 10 in the direction toward the door 1. A bracket 26 that penetrates the top plate 25 of the operating body 9 and projects downward is fixed to the sealing base 10, and an upwardly facing contact body 24 is fixed to the sealing base 10.
4 is brought into contact with the slider 27 provided on the front surface of the bracket 26, the sealing base 10 moves downward against the springs 22 and 23 due to the backward sliding of the actuating body 9, and the actuating body 9 The structure is such that the sealing base 10 is returned to its original position by springs 22 and 23 due to forward sliding. In this case, the spring force in the adjustment spring 16 is
Set to a value larger than the total spring force in 3.

In this configuration, when the door 1 is moved forward along the guide rail 5 and hits the other side of the already stopped door 1, the protruding body 15 protruding from one side of the door 1 that has already moved
moves backward to enter the door 1, and this backward movement is transmitted to the actuating body 9 via the adjustment spring 16, so that the actuating body 9 slides backward.

In this case, the spring force in the adjustment spring 16 is applied to the return springs 22, 2 against the sealing base 10.
By setting the spring force to a value larger than the total spring force in step 3, the sealing base 10 is moved away from the door 1 by the backward sliding of the operating body 9 against the return springs 22 and 23. As it moves downward, the sealing member 20 on the lower surface comes into close contact with the floor surface 2 and is pressed against the floor surface 2 by the force of the adjustment spring 16, so that the gap between the lower surface of the door 1 and the floor surface 2 is reduced. Furthermore, when the door 1 is moved backward, the protruding body 15 and the adjusting spring 16 protrude, while the actuating body 9 and the sealing base 10 are closed by the returning springs 22 and 23. It returns to its original position.

Since the protruding body 15 can move backward against the operating body 9 against the adjustment spring 16 provided therebetween, the protruding body 15 can move backward when the door 1 is closed. By setting the descending distance of the sealing base relative to the moving distance according to the case where the gap between the door 1 and the floor surface 2 is large, it is possible to This prevents the door 1 from being unable to be completely closed due to the protruding body 15 moving backward against the adjustment spring 16 provided between the protruding body 15 and the operating body 9. It can be done.

Note that the sliding body 21' such as a slider in the above embodiment may be replaced with a roller-shaped sliding body 21 as shown in FIGS. 3 and 4, and the sliding element 27 of the bracket 26 may be replaced with a sliding body 21 as shown in FIG. Alternatively, the two return springs 22 and 23 for the sealing base 10 may be used.
As shown in FIG. 3, a single return spring 22 may be used.The present invention is not limited to the sliding door type partition door of the above embodiment, but can also be applied to a normal sliding door type door. Of course, it goes without saying that the present invention can also be applied to pivotable doors, and furthermore, the sealing device may be applied only to the top surface of the door or to both the top and bottom surfaces of the door.
