Description

  The present invention relates to a door-end steadying mechanism for preventing an upwardly suspended sliding door from swinging in the thickness direction.

  Top-hanging sliding doors are used in residential gates. The upper suspension type sliding door can be opened and closed by causing the upper door provided on an upper frame or the like to suspend and hold the sliding door and sliding the sliding door along the upper rail. When such a suspended sliding door is used, the lower rail does not exist, so the installation surface can be flattened and lightly opened and closed. For this reason, there is a problem in that lateral swing occurs in the thickness direction of the sliding door when opening and closing.

  For this reason, for example, in Patent Document 1, a traveling groove having a U-shaped cross-section opened downward is formed on the lower end surface of the hanging door body, and a guide is fitted into the running groove to drive the hanging door body during traveling. A technique for regulating runout in the thickness direction is described. The technique described in Patent Document 1 includes a substrate disposed on the floor, a pair of guide rollers erected on the substrate, and mounting screws for attaching the substrate to the floor. A circular hole and an arc-shaped hole are formed. While the circular hole is temporarily fixed to the floor surface, the substrate is rotated so that the guide rollers abut against the inner surfaces before and after the guide groove. It comes to contact. According to the technology described in Patent Document 1, by providing a pair of guide rollers, the straightness of the sliding door can be improved compared to the case where there is one guide roller, and the guide rollers are arranged before and after the guide groove. Since the clearance between the guide roller and the guide groove can be eliminated by contacting the inner surface, an effect of suppressing rattling can be expected.

JP 2007-182675 A

  However, in the technique described in Patent Document 1 described above, the position of the pair of guide rollers can be adjusted by rotating the substrate. However, since the pair of guide rollers move integrally, a circular hole is used. This error could not be absorbed when the position of the screw temporarily fixed to the floor surface was shifted. That is, when the position of the pair of guide rollers is adjusted by rotating the substrate, the pair of guide rollers rotate integrally around the circular hole, so that the center of the circular hole is shifted from the center of the guide groove of the sliding door. If this is the case, this deviation cannot be resolved. For this reason, there has been a problem that the sliding door is inclined and guided, or a clearance is generated between the guide roller and the guide groove to cause rattling.

  Therefore, the present invention can easily adjust the position of the guide roller even when the initial mounting position of the guide member (or the mounting position of the pedestal) is displaced with respect to the sliding door, and eliminates the clearance between the guide roller and the guide groove. It is an object of the present invention to provide a door-end steadying mechanism for an upper suspension type sliding door that can suppress rattling of the sliding door.

  The present invention has been made to solve the above-described problems, and is characterized by the following.

(Claim 1)

  That is, the guide member is formed such that the position of the guide roller can be adjusted by pivoting about a rotation fulcrum.

(Claim 3)
The invention described in claim 3 is characterized by the following points in addition to the characteristics of the invention described in claim 1 or 2.

  That is, a bolt inserted into the fixing hole of the guide member, and a pedestal having a mounting hole screwed with the bolt, and a plurality of the guide members are connected to the pedestal. .

  The invention according to claim 1 is as described above, wherein a plurality of guide members are continuously provided along the extending direction of the guide groove of the sliding door, and the plurality of guide rollers are in contact with both sides of the pair of inner wall surfaces of the guide groove. By doing so, the clearance between the guide roller and the guide groove can be eliminated, and rattling of the sliding door can be suppressed. In addition, since the position of each guide member can be adjusted independently, the width and direction formed by the plurality of guide rollers can be freely set. Therefore, even when the initial attachment position of the guide member (or the attachment position of the pedestal) is shifted with respect to the sliding door, it is possible to easily suppress the rattling of the sliding door. For example, even when the guide member and the guide groove are deviated in the thickness direction, adjusting the position of the first guide roller adjusts the variation during construction and adjusts the position of the second guide roller. By fixing the swing of the sliding door, it is possible to easily suppress the sliding of the sliding door.

  In addition, since each of the plurality of guide members has a guide roller, the adjustment range of the distance between the shafts and the angle of the guide roller is widened as compared with the case where the guide member integrally formed with the plurality of guide rollers is used. Even when the size of the sliding door or the width of the guide groove is changed, it can be easily dealt with.

  Further, since a plurality of guide rollers are provided, the straightness of the sliding door can be improved as compared with the case of one guide roller. If the distance between the plurality of guide members (guide rollers) is increased, the straightness of the sliding door can be further improved. In particular, when a sliding door with a large area is installed outdoors, the swing width increases due to the influence of wind or the like, but straightness can be ensured even in such a case.

  Further, the invention according to claim 2 is as described above, and the guide member is formed so that the position of the guide roller can be adjusted by pivoting about a rotation fulcrum. Even after this, the position of the guide roller can be easily adjusted by pivoting.

  The invention according to claim 3 is as described above, and includes a bolt inserted into the fixing hole of the guide member, and a pedestal having a mounting hole screwed with the bolt, A plurality of the guide members are continuously provided. Thereby, since the temporary fix position of a some guide member is determined by fixation of a base, workability | operativity can be improved.

  The guide roller 21 is a cylindrical member, and is rotatably attached to the support shaft 22 so as to penetrate the center. The outer periphery of the guide roller 21 is covered with a ring-shaped member made of rubber or resin, and the ring-shaped member comes into contact with the inner wall surface 10b of the guide groove 10a.

  The pedestal 32 is a block-shaped member as shown in FIG. 2, and is for attaching the guide member 20 using the bolt 31. The pedestal 32 is formed so that a plurality of (two in the present embodiment) guide members 20 can be provided continuously along the sliding direction of the sliding door 10. Specifically, four attachment holes 32a for attaching the guide member 20 are connected in a straight line in the longitudinal direction, and one guide member 20 is attached using the two attachment holes 32a on one side, Another guide member 20 can be mounted using the two mounting holes 32a on the other side. At this time, the two center mounting holes 32a are for screwing the bolts 31 that pass through the first fixing holes 23a of the respective guide members 20, and the two outer mounting holes 32a are respectively The bolt 31 that penetrates the second fixing hole 23b of the guide member 20 is screwed together.

In addition, since the position of each guide member 20 can be adjusted independently, the width and direction formed by the plurality of guide rollers 21 can be freely set. Therefore, even when the mounting position of the pedestal 32 is shifted with respect to the sliding door 10, rattling of the sliding door 10 can be easily suppressed. For example, even when the guide member 20 and the guide groove 10a are displaced in the thickness direction, by adjusting the position of the first guide roller 21, variation during construction is adjusted, and the second guide roller 21 By fixing the swing of the sliding door 10 by adjusting the position, it is possible to easily prevent the sliding door from rattling.

  In addition, since each of the plurality of guide members includes the guide roller 21, the adjustment range of the inter-axis distance and angle of the guide roller 21 is larger than that in the case where the guide member integrally formed with the plurality of guide rollers is used. Since it spreads, even when the size of the sliding door 10 or the width of the guide groove 10a changes, it can be easily dealt with.

  Further, since a plurality of guide rollers 21 are provided, the straightness of the sliding door 10 can be improved as compared with the case where there is one guide roller 21. Note that if the distance between the plurality of guide members 20 (guide rollers 21) is increased, the straightness of the sliding door 10 can be further improved. In particular, when the sliding door 10 having a large area is installed outdoors, the swing width increases due to the influence of wind or the like, but straightness can be ensured even in such a case.

  The guide member 20 includes a bolt 31 to be inserted into the fixing holes 23a and 23b, and a pedestal 32 having a mounting hole 32a screwed to the bolt 31, and the pedestal 32 includes a plurality of the guide members. Since 20 is continuously provided, the temporary fixing positions of the plurality of guide members 20 are determined by fixing the pedestal 32, so that the workability can be improved.

  In the above-described embodiment, two guide members 20 are provided. However, the present invention is not limited to this, and three or more guide members 20 may be provided.

  In the above-described embodiment, the pedestal 32 is used. However, the present invention is not limited to this, and the guide member 20 may be directly fixed to the installation place without using the pedestal 32.
