Description

[Detailed description of the invention] [Industrial application field] The present invention is designed to reduce the gap that occurs above or below the door in the closed state in a sliding door such as a partition door or a rotating door pivoted to a room. This invention relates to an improvement in a sealing device for sealing.

[Conventional technology and its problems]

In this type of door sealing device, a sealing base is attached to the upper or lower end of the door so as to be movable up and down, and an operating rod with one end movable in and out of the side edge of the door is attached along the frontage direction of the door. By interlocking and connecting the operating rod and the sealing base via a link mechanism, the operating rod moves backward as the door closes, and the sealing base protrudes toward the ceiling or floor. (Utility Model Application No. 46-28397, Utility Model Application No. 51-127639, Utility Model Application No. 51-127639)
(See Publication No. 16239 and Japanese Utility Model Application Publication No. 52-61069).

However, in the conventional technology using these link mechanisms, in addition to the operating rod that slides in the horizontal direction,
Since a link rod is required to convert the horizontal movement of the operating rod into vertical movement, the number of members inside the door increases and the structure inside the door becomes complicated.

The present invention simplifies the internal structure of the door by directly protruding and moving the sealing base using the operating rod itself.

[Means for solving problems]

That is, in the present invention, a sealing base extending along the frontage direction of the door is attached to either the upper end or the lower end or both of the sliding door type door, the rotating door door, and the sealing base member is movable up and down with respect to the door. A spring that biases the sealing base in a direction close to the door is attached to the spring, and a spring is attached to the spring that biases the sealing base in a direction close to the door. A rotating rod extending in the frontage direction is provided, a midway portion of the rotating rod is pivotally connected to the door so as to be freely rotatable in the vertical direction, and one end of the rotating rod is connected to the door in the direction of the frontage. Projecting from the side end surface, the other end of the rotating rod is connected to substantially the center in the longitudinal direction of the sealing base so that the sealing base moves in a direction away from the door by rotation of the rotating rod. On the other hand, the member facing the end face in the frontage direction of the door has an inclined surface that comes into contact with a protruding end at one end of the rotating rod and rotates the rotating rod when the door approaches. The structure includes a guide means formed by forming a guide means.

[Action/Effect]

In this configuration, when the door is closed, one end of the rotating rod comes into contact with the guide surface of the guide means provided on the mating member, and the rotating rod rotates and the other end pushes out the sealing base. , while the sealing base moves in the direction away from the door, when the door is opened from the closed state, the spring force causes the sealing base to move back toward the inside of the door, and the pivoting rod moves along the inclined guide surface of the mating member. It will rotate back.

Therefore, according to the present invention, since the sealing base is moved away from the door by the lever action of one rotary moving rod, there is no need to use a link rod in addition to the operating rod as in the case of a conventional link mechanism. This has the effect of reducing the number of parts in the door and simplifying the structure of the door.

〔Example〕

Next, an embodiment in which the present invention is applied to a partition door will be explained based on the drawings (Figs. 1 to 4). The partition door 1 is suspended from the rails 5 and is movable along the rails 5. Reference numeral 2 indicates the wall of the room, and reference numeral 3 indicates the floor.

Reference numerals 7 and 7 are sealing devices provided at the upper and lower ends of the partition door 1, and hereinafter, the sealing device 7 at the lower end is referred to as the sealing device 7 at the lower end.
I will explain about it.

At the lower end of the partition door 1, by making the front and back plates 9, 10 of the partition door 1 project downward from the frame 8, a downward opening 11 extending along the frontage direction of the partition door 1 is formed. Opening 1
As will be described in detail below, the sealing base 12 is guided to be movable up and down in the central part of the partition door in the frontage direction and is biased toward the hollow part of the partition door 1; 12 in a direction away from the partition door 1.

The sealing base 12 has a pair of front and back curtain plates 14 extending along the lower edge of the partition door 1 and protruding upward toward the opening 11.
Two flexible seal members 15 made of rubber or the like are fixed to the lower end of the seal member 2 . Furthermore, a sliding body 16 having an L-shape in side view is attached to a substantially central portion of the sealing base 12 in the frontage direction of the partition door 1 with a single bolt 17 . In this case, an elastic body 18 made of rubber or the like is inserted between the head of the bolt 17 and the lower surface of the sealing base 12, and the horizontal base 16' of the sliding body 16 is
The sealing base 12 is made to be tiltable relative to the housing.

The sliding body 16 has a vertical guide plate portion 1 thereof.

The guide plate portion 16'' is provided with vertical and longitudinal openings 21, and the spring case 19 is provided with vertical and longitudinal opening grooves 22 that open upward in parallel with the openings 21. The base end of the movable rod 13 is fitted into the opening groove 22 through the cut-out window 21 and comes into contact with the upper end of the compression spring 20.

A pair of left and right guide plates 2 extend parallel to the front and back curtain plates 14 at the center of the lower surface of the frame 8 in the longitudinal direction.
3 and 23 projecting downward, and vertical guide plate portions 16'' of the sliding body 16 are fitted into vertically longitudinal guide grooves 24 formed with notches in both guide plates 23 so as to be vertically slidable. The sealing base 12 is configured to be able to freely slide up and down along the guide groove 24.A tension spring 25 is mounted between the frame 8 and the sealing base 12 at the center in the front-rear direction.
The sealing base 12 is moved toward the inside of the partition door 1 (upward)
It is pulled in and energized.

The rotation rod 13 is disposed in the gap between the partition door 1 and the sealing base 12 so as to extend along the frontage direction of the partition door 1, and one end (tip) thereof is placed on the frontage direction side of the partition door 1. The rotation rod 1 is made to protrude forward from the end surface 26, while the other end (base end) faces the upper end of the compression spring 20.
A pin 28 is pivotally connected to a bracket 27 projecting downward from the lower frame 8.

On the other hand, the rear end surfaces 2 of the partition doors 1 adjacent to each other
9 and the wall surface 3 of the room located in the forward direction (closing direction) of the partition door 1.
As the movement moves forward (moves in the A direction), the rotating movement rod
As an example of a guide means for rotating the partition door 1, a guide member 32 whose front surface is formed with an upwardly inclined surface 30 is fixed with a screw 33 so that the height position can be adjusted freely.
When it approaches this, the tip of the rotating rod 13 is guided upward by the inclined surface 30, and the base end of the rotating rod 13 is rotated downward, causing the sealing base 12 to protrude downward.

In this case, a substantially horizontal locking portion 31 that continues to the inclined surface 30 is formed on the kicker 32, while a substantially horizontal notch engaging portion 3 is formed at the tip of the rotating rod 13.
4, and when the protruding end at the tip of the rotating rod 13 passes the inclined surface 30, the notch engaging portion 3
4 engages with the horizontal locking portion 31, so that the rotation rod 13 can be maintained in a state in which the tip portion is rotated upward.

In addition, in the sealing device 7 provided at the upper end of the partition door 1, the sealing base 1 is closed as the partition door 1 moves forward.

The base end of the sealing base 12 is pressed through the compression spring 20, and the sealing base 12 moves in a direction away from the partition door 1 against the force of the tension spring 25. When the sealing member 15 of the airtight base 12 comes into contact with the floor 5 or the ceiling, the rotating rod 13 rotates while pressing the compression spring 20 at its base end.
Next, the horizontal engaging portion 34 of the rotating rod 13 engages with the horizontal locking portion 31 of the kicker 32, and the operating rod 13 is held in its position.

In this case, if the rotating rod 13 and the locking member 32 are configured to engage each other with the horizontal engaging portion 34 and the locking portion 31 as in the embodiment, the sealing base 12 is held in the protruding state. What to do and rotation movement rod 1
3 prevents the opposing member from being pressed in the horizontal direction, so the sealing function can be ensured around the four circumferences of the partition door 1, and adjacent partition doors 1 can be kept in close contact with each other. Become. In addition, if the base end (other end) of the rotary movement lever 13 is configured to press the sealing base 12 via the compression spring 20 as in the embodiment, the rotational movement will not occur regardless of the movement dimension of the sealing base 12. Since the movable rod 13 can be rotated to its full extent, even if the upper and lower clearance dimensions of the partition door 1 are different in size, the rotary rod 13 will not get stuck in the middle of rotation and the closed base 1
2 can be brought into reliable contact with the floor or ceiling.

Furthermore, when the sealing base 12 and the sliding body 16 are connected via an elastic body 18 made of rubber or the like, the sealing base 11 can be tilted back and forth with respect to the sliding body 16, so that the upper and lower end faces of the partition door 1, the floor surface, and the ceiling can be tilted back and forth with respect to the sliding body 16. Even if the surfaces are not parallel, it is possible to extremely easily bring the sealing base 12 into close contact with the floor or ceiling surface.
