Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a positioning device for a sliding door whose upper end is suspended and moved.

[Conventional technology]

For sliding doors, the side end surface needs to be in close contact with the mating member when closed.
A sealing member made of an elastic material may be attached to either or both of the end face of the door and the mating member, as disclosed in JP-A-53
As disclosed in Japanese Patent No. 140844, a protruding strip is formed on the side end surface of the door, and a groove strip into which the protruding strip fits is formed on the mating member so that they fit together.

[Problem that the invention attempts to solve]

In that case, if the door is guided along the rails at the top and bottom, there will be no problem of the door tilting to the left or right in the direction of travel, so simply close the gap between it and the mating member. It is only necessary to take this into account, but in the case of a door whose upper end is suspended from a ceiling rail or the like so that it can be moved, there is a problem in that the door is closed in an attitude tilted from side to side when facing the direction of travel.

For this reason, in a door that is moved by suspending its upper end, if a sealing member is simply pasted on the end face as described above, there is a problem that the door may be closed while being tilted. In the case of partition doors, the surfaces of each door would be uneven, resulting in an unsightly appearance. It is not a good idea to form protrusions and grooves on the end face of the door and the end face of the mating member as in the above-mentioned publication, as it is troublesome to process and difficult to fit together.

The present invention solves the above-mentioned problems with a door whose upper end is suspended and moved, and also allows the sealing member to be easily replaced.

[Means for solving problems]

For this reason, in this invention, in a sliding door that is movably suspended from a rail installed on the ceiling surface, etc.
Two elastic sealing members are provided along the vertical direction on one of the front end face of the door and the end face of the mating member that faces the door. At the same time, a protruding body that is slidable along the moving direction of the door and is biased by a spring in a protruding state is disposed at the lower end or both upper and lower ends of the one end face, and the protruding body is connected to the two grooves. On the other hand, an engagement groove with a tapered cross section is formed along the vertical direction in the other end face part of the both end face parts, and the tip part is formed in the engagement groove in the vertical direction. A sealing member made of an elastic material having a convex cross section is fitted between the two sealing members, and a sealing member made of an elastic material having a convex cross section is fitted between the two sealing members. A contacting body with which the body engages is provided protrudingly, the sealing member having a convex cross-section is supported by the contacting member at the lower end, and the contacting body is set so as not to protrude from the sealing member having a convex cross-section. It is configured to do this.

In this embodiment, as described above, the sealing devices 7, 7 are also provided at both the upper and lower ends of the partition door 1, and the operation of the sealing devices 7, 7 is related to the movement of the protruding body 15. In other words, the protruding body 15 has both the function of positioning the partition door 1 and the function of operating the upper and lower sealing bases 7, 7. In this regard, the lower sealing device 7 will be discussed, and FIGS. The explanation will be based on.

The sealing device 7 has a downwardly opening U-shaped cross section and is slidably disposed along the width direction of the partition door 1 within a frame 8 that has a downwardly opening U-shaped cross section and is fixed to the lower end of the partition door 1. It consists of a shaped sliding body 9 and a sealed base 10 fitted into the frame 8 so as to be vertically slidable. Among these, the sliding body 9 has at least two elongated holes 11 bored in its top plate,
The bolts 12 inserted through the elongated holes 11 are screwed into the frame 8, and the slider shoes 13, 13 that sandwich the top plate of the sliding body 9 are fitted onto the bolts 12, so that the partition door 1 can be closed. It is configured to be slidable along the width direction.

Further, the sliding body 9 is formed with an inclined guide surface 14 that tilts upward toward the rear surface of the partition door 1, and at the tip of the sliding body 9, a notch 18 of the front plate 17 of the partition door 1 is formed. Projection body 1 that can appear and appear from
I am wearing 5. In this case, the protruding body 15 is configured to move relative to the sliding member 9 by a certain amount, and a compression spring 16 for buffering is installed between the protruding body 15 and the sliding member 9. Thus, the protruding body 15 is biased in the direction of protruding from the sliding body 9.

On the other hand, the sealing base 10 is provided with curtain plate parts 19, 19 that fit on the outer surface of the sliding body 19, and a pair of left and right seal members 20, 20 are provided at the lower end, and the horizontal part thereof is provided with a pair of seal members 20, 20 facing upward. By bringing the protruding bracket 24 and the bracket 25 protruding downward from the top plate of the frame 8 into contact via a sliding body 26 such as a needle bearing, the sealing base 10 can only move up and down. Configure it so that Further, a rotating roller 21 is provided on the sealing base 10 via a bracket, and by bringing the rotating roller 21 into contact with the inclined guide surface 14 of the slider 9, the sealing base is rotated as the slider 9 moves backward. 10 is configured to protrude toward the floor surface 2.

It is not necessary to connect the sealing base 10 with a separate member for protruding and moving the sealing base 10.
In that case, the protruding body 15 may be biased by a separate spring.

In the above configuration, when one partition door 1 is moved and its front end surface is brought into contact with the rear end surface of the other partition door 1 that is already stationary at a predetermined position,
The protruding body 15 is retracted and its recess 34 is connected to the abutting body 3.
A sealing member 36, which is engaged with the tip of the partition door 2 and positioned in such a manner that both the front and back surfaces of the partition door 1 are in the same plane, protrudes from the front and rear end surfaces of the partition door 1;
36, 31 are the openings 2 of the opponent side frames 28, 35
9, 29, and 37, the gap between the end faces of each other is sealed, and by sequentially bringing each partition door 1 into contact with each other, the room is partitioned. In this case, since the protruding body 15 is biased by the spring, the positioned state is maintained.
Then, when the partition door 1 is moved backward, the protruding body 15 is moved back due to the spring force.

In this case, as the partition door 1 is moved, the protruding body 15 and the abutment body 32 engage, and the partition door 1 is positioned, so that positioning and sealing are performed extremely smoothly. Become. In addition, since the protruding bodies 15 and the abutment bodies 32 are prevented from protruding from the side sealing members 36 and from the central sealing member 31, respectively, the protruding bodies 15 and the abutting bodies 32 are prevented from protruding from the central sealing member 31, so that the protruding bodies 15 and the abutting bodies 32 are prevented from protruding from the central sealing member 31. 15 or the abutment body 32 can be reliably prevented from getting caught unexpectedly. Furthermore,
Among the seal members, a seal member 31 having a convex cross section
Since it is simply inserted into the engagement groove 30 and supported by the abutment body 32, it can be easily removed and replaced.

In addition, as in the embodiment, sealing bases 10 and 10 are also provided on the upper and lower sides of the partition door 1, and the operation thereof is controlled by the protrusion 1.
In relation to No. 5, there is an advantage that the structure of the positioning device and the upper and lower sealing devices can be simplified.

[Functions and effects of the idea]
