Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a sealing device disposed at the upper end, lower end, or both of a sliding door or a rotating door.

Generally, a sliding partition door for dividing a room into small rooms is configured so that its upper end is movably mounted on a guide rail installed on the ceiling of the room.
On the other hand, a rotating door attached to a frontage is pivoted at one side thereof by a hinge, a pivot, or the like. In order to allow smooth forward and backward movement or rotation of any of these doors, gaps are provided so that the upper and lower ends of the door do not come into contact with the upper and lower ends of the frontage, respectively.

In the closed position of this type of door, if the front or rear end of the door hits another place, the conventional sealing device can seal the gap between the top and the bottom of the door, respectively. The tip of the operating rod, which is disposed approximately horizontally along the door, protrudes from the front or rear end surface of the door, and if the tip of the operating rod hits another location, the operating rod retreats along its axis, and The horizontal backward movement of the door is related to the vertical movement of the sealing base through a link mechanism so that it moves upward and downward away from the upper or lower end of the door (see Utility Model Publication No. 46-28397, Utility Model Application No. 51-127639, Utility Model Application No. 51-127639, 1977
-16239). In all of these conventional examples, a link mechanism is required and the structure is complicated, and the horizontal movement dimension of the operating rod is proportional to the vertical movement dimension of the sealing base, and there is no play between the two, so, for example, the operating rod Even if the rod is completely retracted, the closed base may not contact the floor, etc., or conversely, the closed base may contact the floor first, making it impossible to fully retract the operating rod, causing the tip of the operating rod to There were drawbacks such as the problem that the mating member could get stuck.

The purpose of the present invention is to solve this problem, and the gist of the invention is to provide a door along the frontage direction of either the upper end or the lower end of the sliding or rotating door, or both. An extending longitudinal sealing base is attached to the door so as to be movable up and down, and a spring is attached to the sealing base for biasing the sealing base in a direction toward the door. A rotating rod extending in the direction of the door's frontage is installed in the gap formed in the gap extending in the direction of the door's frontage. one end of the pivoting rod protrudes from the end surface in the frontage direction of the door, and the other end of the pivoting lever is attached to a substantially central portion in the longitudinal direction of the sealing base. The sealing base is connected to move in a direction away from the door by the rotation of the rotation lever, while a member facing the end face in the frontage direction of the door is connected to the rotation lever when the door approaches it. Means is provided for rotating the rotating rod by contacting the protruding end at one end, and further, a pivoting portion of the rotating rod at a midway point relative to the door can be moved up and down with respect to the door. The reason is that the structure is elastically supported.

The embodiments of the present invention will be explained below with reference to the drawings. In Figs. 1 to 5, 1 and 1 are partition doors, 2 is a floor surface, 3 is a side wall, 4 is a ceiling surface, and 5 is a system installed on a ceiling surface. The guide rail 5 is a box-shaped guide rail, and although not shown, an open passage is formed on the lower surface of the guide rail 5 along its longitudinal direction.

Reference numerals 6 and 6 refer to rotating rollers provided at the upper end of the hanging rod that protrudes upward from an appropriate location on the upper end of each partition door 1 and faces the opening passageway, and is configured to move along the inner guide surface of the guide rail 5. has been done.

Numerals 7 and 7 are vertically symmetrical sealing devices provided at the upper and lower ends of each of the partition doors 1 along the opening direction thereof.Hereinafter, the sealing device 7 at the lower end will be explained.

A longitudinal lower frame 8 along the frontage of the partition door 1
A front plate 9 and a back plate 10 of the door are provided on the front and back surfaces of the door, respectively, and the lower ends of both the front and back plates 9 and 10 face downward from the lower frame 8, and a longitudinal downward opening opening 11 extends along the door frontage direction. form.

Inside the frontage part 11, there is a sealing base 12 which is guided so as to be movable up and down in the central part of the door in the frontage direction and which is biased toward the inside of the door. A sealing device 7 consisting of a rotating rod 13 that presses away from the housing is housed.

The hermetic base 12 has a pair of front and back longitudinal curtain plates 14, 14 protruding from its upper surface along the longitudinal opening 11, and a flexible material made of rubber or the like on the opposite side (lower surface) to the two curtain plates 14, 14. A pair of longitudinal sealing members 15, 15 bases having a diameter are fitted therein. A horizontal base 16' of a sliding body 16 having an L-shape in side view is attached to the upper surface of the sealing base 12 at the center in the longitudinal direction with a single bolt 17. An elastic body 18 made of rubber etc.
By interposing the sealing base 12 so as to be tiltable with respect to the horizontal base 16' of the sliding body 16, the lower surface of the sealing member 15 of the sealing base 12 is not horizontal regardless of the vertical movement of the sliding body 16. Side 2
It is designed to be able to run closely parallel to this.
Further, the vertical guide plate portion 16'' of the sliding body 16 has an engaging portion 19 such as a vertically longitudinal opening groove that opens upward.
is provided so that the rear end portion of the rotating rod 13, which will be described in detail later, can come into pressure contact with the sliding body 16.

A pair of guide plates 20, 20 projecting downward from the center of the lower surface of the lower frame 8 in the longitudinal direction are disposed between the front and back curtain plates 14, 14 of the sealing base 12 in parallel therewith, and both the guide plates 20, 20 are vertically open vertical longitudinal guide grooves 2 for vertically slidingly guiding both ends of the vertical guide plate portion 16'' of the sliding body 16.
1 and 21 are cut out.

A tension spring 22 is installed between the frame body 8 and the sealing base 12 at the center in the longitudinal direction, and the tension spring 22 biases the sealing base 12 in a direction toward the door 1. Configure.

The other end of the rotating rod 13 faces the upper end of the sliding body 16 of the sealing base 12, and the rotating rod 13
3 is disposed within the opening 11 so that one end thereof protrudes forward from the front end face 23 in the door movement direction, and the midway portion of the rotation rod 13 is elastic so that it can freely rotate toward the door body side and can move up and down. For example, in the illustrated embodiment, a pair of support brackets 24, 24, which are disposed to sandwich the rotation rod 13 from both the front and back sides, have horizontal locking portions 25,
25 is the hole 2 drilled in the top plate 8' of the lower frame 8.
6, 26' and then shifted as appropriate and locked onto the upper surface of the top plate 8', and fixed with screws 27. Upper and lower longitudinal engagement holes 28, 28 are formed in the support brackets 24, 24, respectively, and an abutment portion 29 having a thickness _t1 is provided on the lower surface of the upper end of each bracket 24, respectively. On the other hand, a pin 30 horizontally protruding from the rotation rod 13 is passed through the engagement holes 28, 28 of the support brackets 24, 24, and the pin 30 is formed in the shape of a disk or the like at both front and back ends. When the elastic bodies 31, 31, such as urethane rubber, are fitted, and an upward force is applied to the rotating rod 13, both the elastic bodies 31,
31 is configured such that the upper end thereof abuts on the abutting portion 29, each elastic body 31 is elastically deformed, and the rotational movement rod 13 is upwardly displaced against the elasticity. The front and back ends of the pin 30 may be respectively supported by a pair of upper and lower compression springs, or the pin 30 may be elastically supported by the support brackets 24, 24 via leaf springs or the like.

Furthermore, the rear end surface 32 of the adjacent partition door 1
In addition, on a mating member such as a wall surface 3 that the front end of the moving partition door 1 comes into contact with, a locking member 35 having an inclined surface 33 and a horizontal locking portion 34 is attached with screws 36, 36 for vertical position adjustment. As one end of the rotating rod 13 approaches the kicker 35, the rotating rod 13 is stopped by the inclined surface 33 of the kicker 35.
It is configured so that one end thereof is pushed up, and a substantially horizontal notch engaging portion 37 is provided on the lower surface of one end of the rotating rod 13, and a substantially horizontal locking portion 34 that continues to the inclined surface 33
When the engaging portion 37 is placed on the position, the state is maintained;
The downward rotation of one end side of the rotation rod 13 can be prevented.

With the above configuration, when the partition door 1 is moved forward in the direction of arrow A and one end of the pivoting rod 13 protruding from the front end surface 23 of the door rides on the inclined surface 33 of the kicker 35 of the rear end surface 32 of the partition door 1 placed in the front. As a result, the rotating rod 13 rotates at the 30 pins so that the other end of the rotating rod 13 faces downward, and the lower surface of the other end of the rotating rod 13 is attached to the sliding body 16 at the longitudinal center of the sealing base 12. The upper end of the vertical guide portion 16'' is pressed downward, and the sealing base 12 is lowered in a direction away from the door against the force of the tension spring 22 between the door body side and the sealing base 12.Then, the sealing base 12 is sealed. When the lower surface of the member 15 comes into contact with the floor surface 2, as the slope 33 of the kicker 35 pushes up one end of the rotating rod 13, the elastic body 31 at the pin 30 is elastically deformed, causing the rotating rod 13 to move upward. The one end side is displaced upward.Moreover, due to the elasticity of the elastic body 31, the rotational movement rod 13
The sealing base 12 is pressed against the floor surface 2 with its longitudinal center portion.

Next, one end of the rotating rod 13 has a horizontal engaging portion 37.
When the lever 13 rides on the horizontal locking part 34 of the kicker 35, the operating rod 13 maintains that state, and the adjacent partition doors 1, 1 do not move away from each other, and pressurizes the seal member 15 against the floor surface 2. It can be held closely in any condition.

When the present invention is applied to a rotating door, the related parts between the other end of the rotating rod 13 and the sealing base 12 are constructed in the same manner as in the previous embodiment, and one end of the rotating rod 13 is connected to the door. Protrude from the rear end face of the door near the rotation axis, bend one end of the operating rod 13 into an L-shape in plan view, and place a roller at that point so that the rotation axis is approximately parallel to the longitudinal axis of the rotation movement rod 13. At the same time, in the closed position of the door 1', a cutout part of the wall surface or member that faces the rear end surface of the door is provided with an inclined surface on which the lower surface of the roller rides as the door is rotated to close. It is screwed down so that its vertical position can be adjusted freely. Further, the locker is formed with a horizontal locking portion following the slope surface, with which the lower surface of the roller stably contacts in the door closing position, and the locking portion is formed by the force of the tension spring 25 acting on the rotation rod 13. The door is configured so that it does not rotate in the opening direction even if the door is opened.

In addition, contrary to the above-mentioned embodiment, the roller at one end of the rotary lever 13 is made to protrude from the front end face far away from the pivot axis of the rotary door, and the frontage wall facing it is provided with a roller similar to that described above. It goes without saying that even if a sealer is provided, the same sealing effect as in the embodiment described above can be achieved.

In summary, the present invention has the structure described in the claims of the utility model registration, and the sealing base can be directly moved away from the door by the lever action of the rotating operating rod, unlike the conventional method. There is no need for a link mechanism that associates the horizontally movable operating rod with the vertically movable sealing base, making the structure extremely simple. Moreover, in the present invention, by elastically supporting the pivoting portion of the pivoting rod to the door so as to be able to move up and down with respect to the door, the sealing base and the
Even if the vertical gap with the floor surface, etc. is small, it is possible to eliminate the gap between the end face in the direction of the door frontage and the member facing it, so that they can be brought into close contact with each other. This has the effect of increasing tolerance to size and also being able to apply pressure to the floor surface of the hermetically sealed base.
