TECHNICAL FIELD OF THE INVENTION
The present invention relates to a doorway closing device for a hanging sliding door.
[0002]
[Prior art]
Hanging sliding doors have been used widely since they can flatten the floor surface.However, in order to avoid rubbing the walls etc., the sliding doors simply run horizontally away from the walls etc. to open and close the outer surface of the doorway I am trying to do it.
[0003]
[Problems to be solved by the invention]
Therefore, when the door is closed by closing the sliding door and running, a gap is formed between the door and the door, including the floor surface at the lower end, and the room lacks soundproofing due to the inflow of external sound, and electromagnetic waves and the like are generated. There is a problem that it flows into the room and causes radio interference such as malfunctions in indoor equipment in a hospital, precision equipment in a equipment room, and measurement equipment. Therefore, we have tried to move the sliding door to the doorway side and lower it during the closing travel to seal it.However, due to the structural instability of the hanging sliding door called hanging travel, the sealing was incomplete or short term. There is a problem that a failure or the like occurs and the device cannot be used.
[0004]
[Means for Solving the Problems]
The present invention arranges a vertical frame on both sides in the opening and closing direction of the hanging sliding door, so as to open and close the hanging sliding door together with the vertical frame, to move the hanging sliding door up and down and forward and backward based on the vertical frame. This problem can be solved by allowing the four rounds of the doorway to be sealed including the floor surface after the vehicle has closed and traveled.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
As shown in FIG. 1, a sliding door 3 which is suspended under an upper rail 1 and travels open and closed has vertical frames 4a and 4b on both sides in the opening and closing direction, and opens and closes and travels together with the vertical frames 4a and 4b. Are moved up and down and forward and backward based on the vertical frames 4a and 4b, so that after closing and traveling, four rounds of the doorway can be sealed including the lower floor surface.
[0006]
An example of a structure in which the hanging door 3 is moved up and down and moved forward and backward to seal the door is described below.
[0007]
A traveling body 2 provided with rollers 2a for traveling is provided in the upper rail 1 so that the hanging sliding doors 3 can be opened and closed with the vertical frames 4a and 4b arranged on both sides in the opening and closing direction. 2a is a running roller. Reference numeral 5 denotes an intermediate frame provided on the traveling body 2, which travels with the traveling body 2 and is vertically supported by coil springs 6a and 6b provided at both ends thereof. As shown in FIG. 4, the horizontally rotating disks 7 provided at two intermediate positions on both sides of the intermediate frame 5 are provided with long holes 7a in the radial direction, and the hanging shafts 8a and 8b of the sliding door 3 are suspended in the long holes 7a. The sliding door 3 is supported so that the sliding door 3 can linearly advance and retreat by a half turn of the disk 7 by being mounted downward. Reference numeral 9 denotes a moving body which is supported on the traveling body 2 by a support plate 9a so as to be able to move laterally. The moving body 9 is manually or electrically driven and laterally moves. An inclined hole 10 whose opening direction is low is provided, and a projection 12 at an upper end of a connecting rod 11a attached to a vertical moving plate 11 which is respectively suspended in vertical frames 4a and 4b is fitted into both inclined holes 10. As shown in FIG. 2 and FIG. 3, both moving plates 11 move up and down at the same time as the moving body 9 moves laterally.
[0008]
As shown in FIG. 5, each of the vertical frames 4a and 4b is formed of three pieces from the sliding door 3 side with the vertical moving plate 11 interposed therebetween. A play hole 14 is provided on the sliding door 3 side with the inclined guide hole 13 provided therebetween, and an inclined guide hole 15 is provided inside the inclined guide hole 13 so as to cross the inclined guide hole 13. Each support shaft 16 projecting from the suspension sliding door 3 is inserted so as to pass through the play hole 14, the inclined guide hole 13 and the inclined guide hole 15. 4c is a cover member for the vertical frames 4a and 4b. These mechanisms on the other side are provided symmetrically with FIG. Reference numerals 17a and 17b shown in FIG. 1 denote stopper mechanisms for preventing the vertical frames 4a and 4b from running back and forth during traveling, and preventing and fixing the vertical frames 4a and 4b from running when the door is closed. This rail is provided only on the door pocket side to prevent the front and rear shakes during running and when the door is closed by fitting with the stopper 17b. As shown in FIG. 1B, the stopper 17a is fitted to the vertical frame 4a when the door is closed, and fixes the vertical frame 4a so as to prevent front and rear movement.
[0009]
As described above, when the hanging sliding door 3 is closed and travels together with the left and right vertical frames 4a and 4b and reaches the front of the doorway 19, the moving body 9 is manually or electrically moved in the closing direction, as shown in FIG. The upper and lower moving plates 11 on both sides in the vertical frames 4a and 4b are simultaneously lowered by the projections 12 at the upper ends being guided to the lower ends of the inclined holes 10. With the lowering of the upper and lower moving plates 11, the support shafts 16 on both sides of the suspension sliding door 3 move in the inclined guide hole 13 and advance together with the suspension sliding door 3 to the doorway 19 while simultaneously guiding the inclination guiding hole 15 to descend. Therefore, the hanging sliding door 3 descends while moving forward, and seals the four circumferences of the doorway 19 including the floor surface 20.
[0010]
During this time, the suspension shafts 8a and 8b make the suspension sliding door 3 move down by the lowering of the intermediate frame 5 and the forward movement of each of the disks 7 by a half turn, thereby performing a reasonable sealing operation. The hanging sliding door 3 is prevented from moving forward and backward of the vertical frames 4a, 4b by the anti-sway rail 18 and the anti-skid stoppers 17a, 17b, so that the vertical frames 4a, 4b are used as pillars to stably advance and descend. It can be performed reliably. Although not shown in the drawings, a sealing buffer member for both soundproofing and shielding of electromagnetic waves and the like is attached to the four circumferences of the doorway 19 and the inner surface and lower surface of the suspension sliding door 3 or both.
[0011]
When the hanging sliding door 3 is opened and rotated, the moving body 9 is first moved laterally in the opening direction to move the upper and lower movable plates 11 upward to guide the respective support shafts 16 in the upwardly inclined direction of the inclined guide holes 15. It is retracted while moving up. The hanging sliding door 3 retreats while moving upward without rubbing the floor surface 20, separates from the doorway 19 and the floor surface 20, and then opens and runs to open the front of the doorway 19.
[0012]
During this time, the suspension door 3 descends, that is, the coil springs 6a and 6b compressed by the lowering of the intermediate frame 5 are extended, and the coil spring 6c stretched between the moving body 9 and the intermediate frame 5 as shown in FIG. The suspension door 3 can be moved upward gently regardless of its weight by the compression action of the coil spring 6d stretched on the vertical moving plate 11 in the vertical frames 4a, 4b, respectively, and the suspension shafts 8a, 8b are also intermediate frames. The upward movement of the disk 5 and the half rotation of the disks 7 follow the upward movement of the disk.
[0013]
Although the inclined guide hole 15 shown in FIG. 5 is formed in a shape composed of a horizontal portion and an inclined portion, the lower end of the hanging sliding door 3 is fitted to the floor surface 20 as shown in FIG. When the floor 20 is smooth as shown in FIG. 8B, the inclined guide hole 15 is also simple. A simple inclined shape is sufficient.
[0014]
The opening and closing of the hanging sliding door 3 can be automated using a known automatic door opening and closing mechanism (not shown). The operation can be fully automatic by operating a switch (not shown) provided on a wall or a hanging sliding door in conjunction with a motor operation, and an operation handle 21 for moving the moving body 9 sideways as shown in FIG. It is also possible to manually operate everything including opening and closing traveling. In any case, the above-mentioned auxiliary mechanism of the coil spring makes it possible to operate the apparatus smoothly with little burden on humans and machines.
[0015]
【The invention's effect】
As described above, the present invention opens and closes the hanging sliding door together with the vertical frames on both sides, and moves up and down and forward and backward with the stable vertical frame as a base point, and seals four rounds of the door including the floor when the door is closed. With this configuration, it is possible to prevent external sound from flowing into the room, and in particular, prevent electromagnetic waves from entering the room, thereby preventing the precision instruments from malfunctioning.
[0016]
The vertical moving plate is inserted in the vertical frame, and this is linked to the moving body provided on the traveling body, so that the hanging sliding door moves up and down and forward and backward, so the operating mechanism for sealing is simple. Since the door is protected by the vertical frame and the like, it can be operated without failure for a long time, and the hanging door can be smoothly moved up and down and forward and backward to seal the door.
[0017]
An auxiliary mechanism with a coil spring installed in the right place reduces the operating load when the sliding door is moved upwards, making it possible to operate it very lightly in manual operation, and to reduce wear and tear on motors and gears in electric operation. As a result, there is an effect that the device life can be maintained long.
