DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension height adjusting device for a suspension door provided at an entrance or a passage of a building.

[0002]

2. Description of the Related Art In general,
In this type of suspension door, a plurality of retainers are supported between an inward guide groove above and below the outer slide rail and an outward guide groove above and below the inner slide rail where the door body is supported. The above-mentioned ball is suspended using a slide-type suspension rail interposed in a freely rotatable manner, so that the opening and closing movement of the door body can be performed more smoothly than that of the suspension roller type.

[0003] An example using such a slide type suspension rail is disclosed in Japanese Utility Model Publication No. 61-453. However, when such a slide type rail is used, it is required that the rail be installed horizontally. For this reason, the conventional type has a long hole for position adjustment on a rail frame to which the slide type rail is integrally attached. On the other hand, the rail frame is made horizontal by adjusting the screwing amount of an adjustment bolt projecting from the upper surface of the rail frame, and then the rail frame is fixedly assembled. However, in the building, the members become familiar with each other due to curing after the assembly is completed, which may cause displacement, distortion, or bending, and these factors may cause the sliding rails to be mounted. Horizontality may be impaired. However, in the above-mentioned conventional one, it is not assumed that the slide type rail is once again horizontally adjusted after assembling.
In order to adjust the level after installing the assembly, it is necessary to adjust the adjustment bolts on the upper surface of the rail frame after disassembling the assembled assembly, which necessitates a large-scale construction. Therefore, the appearance of a mechanism capable of easily leveling the slide rail has been demanded.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has been made in order to provide a suspension height adjusting device for a suspension door which can eliminate these disadvantages. A ball supported by a retainer between an inward guide groove above and below an outer slide rail integrally attached to the skeleton and an outward guide groove above and below an inner slide rail on which the door body is supported. In the hanging door, the door body is movably opened and closed by using a sliding suspension rail interposed rotatably,

[0006]

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a door constituting a suspension door provided at an entrance or a passage of a building, and the door 1 is provided with a sliding suspension rail 2 described later provided at an upper portion of the opening.
From the closed position to close the opening,
It is provided so as to be able to move left and right within a door pocket 3 provided inside the room on one side of the opening and reaching a storage position where the opening is opened.

Here, the slide type suspension rail 2 is integrally attached to the skeleton side, and supports the outer slide rail 4 in which the guide grooves 4a and 4b are formed vertically inward and the door body 1, and An inner slide rail 5 formed with vertically outward guide grooves 5a and 5b, and a plurality of balls 6 rotatably interposed between the opposed guide grooves 4a, 5a and 4b and 5b, And a retainer 7 for supporting the balls 6 in a series at predetermined intervals. Then, the movement of the retainer 7 with respect to the outer slide rail 4 and the movement of the inner slide rail 5 with respect to the retainer 7 are simultaneously performed by the rolling of the ball 6, whereby the movement of the inner slide rail 5 with respect to the outer slide rail 4 is performed. It is configured as follows.

[0008] The mounting of the suspension rail 2 on the skeleton side is as follows. First, in a state in which a substantially U-shaped reinforcing member 4c is applied to the outer surface of the outer slide rail 4, one side surface 8a of the substantially square tubular rail receiving member 8 is integrally stopped via a screw 8b. On the other hand, a rail-side suspension fitting 9 for connecting to the door body 1 is integrally fixed to the inner slide rail 5 via a screw 9a. Then, the other side surface 8 of the rail receiving member 8
c is applied to the frame member 10 integrally built on the upper side of the skeleton side of the opening, and is integrally fastened by screws 11. The present invention is applied to a fastening structure.

In other words, a vertically long mounting slot 8e is formed in the mounting side 8d extending upward from the other side surface 8c of the rail receiving member 8.
The vertical position of the suspension rail 2 can be adjusted within the length range of e. Further, the frame member 10
Has a support side 10a which is bent so as to contact the lower surface 8f of the rail receiving member 8 from below, and is screwed into a screw hole 10b formed in the support side 10a from below. The upper end of the adjustment screw 12 for height adjustment is brought into contact with the lower surface 8f of the rail receiving member, and the vertical movement of the rail receiving member 8 is adjusted based on the vertical adjustment movement of the adjusting screw 12. Thereby, the horizontal adjustment work of the slide type suspension rail 2 is performed. In order to perform such horizontal adjustment, the adjusting screw 12 is used.
It is necessary to provide at least one at each of the left and right ends, and in this way, the suspension height of the door body 1 can be adjusted in addition to the horizontal adjustment. Incidentally, the adjusting screw 12 is biased toward the outer door body guide surface 10d between the inner and outer door body guide surfaces 10c and 10d formed on the frame member 10, and is arranged at a position facing downward. It is set. In addition, the inner door body guide surface 10
c is a frame cover 10e for inspection which is detachably fastened to the frame member 10 on the skeleton side, while the outer door body guide surface 10d is provided integrally with the frame member 10 on the skeleton side. It has become.

The hanging of the door body 1 with respect to the rail-side hanging bracket 9 is as follows. In other words, hook portions 9b each having a substantially U-shape are formed at the lower left and right lower ends of the rail-side hanging bracket 9. On the other hand, on the upper surface of the door body 1, the door body side hanging metal fittings 13 are integrally provided corresponding to the hook portions 9 b, but the hanging pieces 13 a provided on the door body side hanging metal fittings 13 have long holes. A through-hole 13b is formed, and the hook 9b is engaged with a pin 14 supported through the through-hole 13b to suspend the door body 1 on the inner slide rail 5. Further, a stopper member 15 is integrally provided on the upper surface of the door body 1,
The retaining member 15 is configured such that the retaining side 15a formed at the distal end edge is loosely fitted in a guide groove 10f formed by bending a plate material to form the outer door body guide surface 10d. The body 1 can be stopped. In the figure, reference numeral 16 denotes a self-closing device for the door 1, reference numeral 17 denotes a shock absorbing device for buffering an impact when the door is fully closed, and reference numerals 18 and 19 denote holding devices for holding the fully opened door 1. , Can be optionally attached as an option, and details thereof are omitted here.

In the embodiment of the present invention configured as described above, the sliding suspension rail 2 is provided with a rail receiving member 8.
Is attached to the frame side by fixing it to the frame member 10 at the upper part of the opening, and the slide type suspension rail 2 to be attached adjusts the adjusting screw 12 up and down with the screw 11 loosely held in the temporary holding state. And after adjustment,
The rail receiving member 8 may be fixed to the frame member 10 by tightening the loosened screws 11.

As described above, according to the embodiment of the present invention, the suspension rail 2 can be horizontally adjusted. However, this horizontal adjustment is not performed by adjusting the entire upper frame member as in the related art. The work of adjusting the suspension rail 2 relative to the member 10 in the vertical direction can be improved, and the workability can be improved. As a result, in the case where the horizontality is impaired due to misalignment or distortion of the members after the installation, it can be easily adjusted without the need for a large-scale construction for dismantling. In addition, this adjustment work can be performed easily by adjusting the up and down movement of the adjustment screw 12 screwed to the support piece 10a formed on the frame member 10, but the adjustment screw 12 is located on the side closer to the outer guide surface 10d. Since it is arranged at a position where it can be seen from below, the adjustment work can be performed by inserting a suitable tool such as a screwdriver from below, and the workability can be further improved.

[0013]

In summary, since the present invention is constructed as described above, the slide type suspension rail is mounted by fixing the rail receiving member fixed to the outer slide rail to the frame member on the skeleton side. However, since the rail receiving member is attached to the frame member so that the vertical position can be adjusted, when the position of the sliding suspension rail is adjusted with respect to the skeleton side, the sliding suspension rail is connected to the frame as in the related art. Rather than making adjustments for each member, it is only necessary to adjust the vertical movement of the slide type suspension rail with respect to the frame member, so that workability can be improved, and therefore, even when adjusting after installation, It can be easily adjusted without major construction work such as dismantling.
