Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition device which facilitates vertical position adjustment of a partition door.

[0002]

2. Description of the Related Art Conventionally, a partition has been used to divide an indoor space in accordance with the usage situation. As shown in FIG. 14, many of the partitions have a rail 60 on the ceiling side, a runner 61 that can run freely along the ceiling rail 60, and a partition wall 62 suspended by the runner 61. The upper and lower surfaces of the partition wall 62 are each provided with an upper fillet 63 and a lower fillet 64 that are vertically movable, and if the partition wall 62 is installed at a predetermined position, it is a separate rotating handle. Is engaged with a bolt (not shown) in the small edge portion of the partition wall 62 to rotate the bolt,
The upper fillet 63 can be brought into close contact with the ceiling surface and the lower fillet 64 can be brought into close contact with the floor surface.

On the other hand, when accommodating the partition walls 62, 62 ..., As shown in FIG. 15, a rectangular accommodating section rail 65 is continuously provided at the end of the ceiling rail 60, and the work vehicle is operated as described above. Partition wall 62 One side runner 61
By being guided to the storage portion rail 65 so that it can be inverted by 90 ° in a plane so that the partition walls 62, 62 ... Can be stored while being overlapped. In use, the partition walls 62 are pulled out to the ceiling rail 60 and moved to a predetermined position by the reverse procedure.

However, in the case of the partition device, the runner 61 must be guided along the storage section rail 65 during the door storage work and the drawer work, and a delicate operation is required while gazing at the runner 61. Therefore, it has been a very troublesome work. Further, each partition wall 62 is finally fixed, and the movement of each room is enabled or disabled by one or more partition walls with doors. For example, in the case of a partition for a general house, an opening / closing door is provided. Sliding door styles tended to be preferred over styles, and there were no partitions in the past to meet these demands.

Therefore, the present applicant has previously filed Japanese Patent Application Laid-Open No. 10-140920.
In the publication, a plurality of rails having two rail grooves are arranged on the floor side and the ceiling side, respectively, and a partition door is provided on the upper and lower parts of one end on the one side and on the upper and lower parts of the other end on the other side, respectively. A guide roller that engages with the floor-side and ceiling-side rails is provided, and the guide roller is movable along the arrangement direction of the floor-side and ceiling-side rails. The roller is detachable from the floor-side and ceiling-side rails, disengages from the floor-side and ceiling-side rails when the partition door is housed, and planarly with the other edge side as the center of rotation. We proposed a partition device that can be rotated and stored.

In such a partition device, it is usually possible to adjust the vertical position of the partition door and to adjust the clearance between the partition door and the floor surface. In the partition device proposed by the present applicant, as shown in FIG. 16, a holding bolt whose head is held by the upper flange 66a of the first bending plate 66 and the upper flange piece 67b of the second bending plate 67. 70 is held rotatably around the screw axis in a fixed state, the threaded portion 70a of the holding bolt 70 is inserted through the slide body 68, and the nut is fitted in the cutout recess 68b on the side of the slide body 68. 69 is screwed into the slide body 68 by rotating the holding bolt 70 with a predetermined screwdriver.
The vertical position of the partition door can be adjusted by moving up and down.

[0007]

However, in the adjusting mechanism described above, a screwdriver must be inserted into the holding bolt 70 in an oblique direction to rotate the screw, and the cross engaging portion at the tip of the screwdriver and the holding mechanism must be held. The bolt 70 is insufficiently engaged with the cross engagement groove, and the work in an unnatural posture is inevitable, which causes a problem that adjustment is troublesome and the position at which the nut 69 is disposed. Is the slide body 68
Since it is eccentric to the side end face side of the slide body and gives a bending moment to the slide body 68 when moving in the vertical direction, friction is increased on the sliding surface of the slide body 68, that is, the second bending plate 67 surface, and smooth vertical movement is impossible. There was a problem. Further, there is a problem that the size of the vertical adjusting mechanism becomes large.

Therefore, a main object of the present invention is to store the partition device when not in use by making a partition device provided with a roller device at each of four corners of the partition door and a guide roller at one end of the partition to be detachable from a rail. Another object of the present invention is to make it possible to easily adjust the vertical position of the partition door and to make the vertical adjustment mechanism compact in a partition device which can be easily pulled out during use.

[0009]

As an invention according to claim 1 for solving the above-mentioned problems, a lower rail is arranged on the floor side and an upper rail is arranged on the ceiling side, and one of the partition doors is on the side of the saw. At the end, an upper roller device having a guide roller for the upper rail and a lower roller device having a guide roller for the lower rail are respectively provided, and at the other end, the upper roller device having a guide roller for the upper rail is provided. In a partitioning device provided with a roller device and a lower roller device having a guide roller for the lower rail, the lower roller device at the one end of the one end and / or the other end of the end part of the lower roller is inserted with the holding shaft of the guide roller. In this state, it is rotatably supported around the shaft center, has a threaded portion formed on the peripheral surface, and has a gear along the circumferential direction. The geared cylindrical gear member is rotatably supported around a horizontal axis while meshing with the gear, and a screwdriver engagement groove is formed on the outer surface side, and the cylindrical gear member is driven by a rotating operation. And a vertical position adjusting gear to be rotated, a threaded portion is formed in the hollow inner surface portion, is provided by being screwed into the tubular gear member, and the holding shaft of the guide roller is inserted at a substantially central position, An up / down position adjusting mechanism portion is provided which supports a holding shaft of a guide roller and is configured to move up and down in accordance with the rotation of the tubular gear member, and the up / down position adjusting gear is rotated by a screwdriver. Thus, the partition device is provided in which the tubular slide body is moved up and down, and the vertical position of the partition door can be adjusted.

According to the first aspect of the present invention, a tubular gear member that is fitted onto the guide roller holding shaft is provided, and a vertical position adjusting gear that meshes with the tubular gear member is provided. A tubular slide body is provided which is screwed into the tubular gear member and is vertically moved by the rotation of the tubular gear member and which supports the guide roller holding shaft. Therefore, in adjusting the vertical position of the partition door, by engaging and rotating a screwdriver from the horizontal direction in the engaging groove formed in the vertical position adjusting gear,
You will be able to adjust easily without being forced to take any posture. Further, since the guide roller holding shaft is a mechanism that inserts the inside of the tubular gear member and the tubular slide body and rotates the tubular gear member to move the tubular slide body up and down. The tubular slide body can be smoothly moved up and down without structural eccentricity. Further, since the guide roller holding shaft is inserted through the inside of the tubular gear member and the tubular slide body, the structure can be made compact.

Next, according to a second aspect of the present invention, an actuating device is provided at an intermediate position between the upper roller device and the lower roller device at one end of the partition door on the side of the row.
