DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a door supporting device which is attached to a slide bar movably along the eyes and is opened and closed by sliding and swinging.

<Prior Art> Conventionally, as a slide / swing type door of this type,
The one shown in the figure is known. This door 30,30
Is rotatably attached via hinges 33, 33 to the lower surface outer ends of a pair of slide bars 32, 32 that run on a rail (not shown) that extends horizontally in a seamless space 31 in the opening. Locking devices 34, 34 for locking the two are provided between the inner end of the upper frame 42 and the slide bar, and the slide bars 32, 32 are tensioned between pulleys 35, 35 provided at both ends in the seamless frame 31. Both doors 30 and 30 are slid to be opened and closed by connecting the upper and lower sides of the toothed belt 36 which is bridged, respectively, and driving the pulley 35 forward or backward by a motor 37. Further, when a wider frontage is required when carrying in / out a large object or in the case of a fire, as shown in FIG. 5, both doors 30, 30 are first slid in the direction of arrow A and then fully opened by arrow B. When it is pushed out like this, the engagement of the locking device 34 between the door 30 and the slide bar 32 is released, and the door swings around the hinge 33. At the same time, the fixed doors 38, 38 on both sides are also hinged 39, respectively. It is swung around 39 and fully opened to obtain an opening twice as large as usual.

By the way, the slide / swing type door 30 is attached to the slide bar 32 at one end of the upper frame 42 via the hinge 33, and most of the weight of the door 30 is applied to this portion. In addition, the structure shown in FIG. 6 is provided so that the door tip at the opposite end to the hinge 33 can be corrected when it is lowered due to installation. That is, the hinge 3 is attached to one end of the slide bar 32 via the bearing 40.
3 is rotatably attached to the lower end of the hinge 33, and the base end of the swing bar 41 whose upper end is an inclined surface 41a is fixed to the lower end of the hinge 33.
The support plate 42 fitted on the upper frame 42 and provided on the upper surface of the upper frame 42.
A wedge 43 having a nut 44 is movably inserted into the flange 43a at the outer end between a and the inclined surface 41a of the swing bar 41, and a shaft is provided on the lower surface of the tip of the swing bar 41 via a stop ring 45. End 46 of the feed bolt 46 attached even if it extends laterally so that it cannot move in any direction and can rotate.

Then, after loosening the screw 47 for fixing the support plate 42a and the swing bar 41, the head 46a of the feed bolt 46 is turned right and left with a hexagon wrench to move the wedge 43 forward and backward, and the door tip of the door 30 is moved up and down by a desired amount. After the movement, the screw 47 is tightened again to adjust the inclination of the door.

<Problems to be Solved by the Invention> However, in the conventional supporting device for the slide / swing type door 30, the long feed bolt 4 is provided on the lower surface of the swing bar 41.
6 is installed laterally immovably in the axial direction, and a supporting plate is provided on the upper surface of the upper frame 42.
Since the structure is complicated such that 42a is provided and the support plate 42a and the swing bar 41 are fixed with screws 47, the number of parts increases, the product cost increases, and the product becomes heavy. In addition, since the swing bar 41 is closely fitted between the vertical frame 48 of the door 30 and the support plate 42a of the upper frame 42 via the wedge 43 indirectly attached to the swing bar 41, a wedge portion or the like is formed. When a failure occurs, the vertical frame 48, 48
It is necessary to remove the bolt 50 for laterally connecting each of them and disassemble and repair each time, which is disadvantageous in that repair and maintenance become very complicated.

Therefore, the purpose of the present invention is to reduce the product cost and reduce the weight, and with a simple structure, it is possible to easily adjust the tilt of the door and the descent of the door, and to perform inspections such as repairs. An object of the present invention is to provide a support device for a door that is easy to maintain.

<Means for Solving Problems> In order to achieve the above object, a door supporting device of the present invention is provided with a slide bar movably provided along a blind spot, and a base provided on a lower surface of the slide bar. A swing bar that is pivotally attached via a rotary shaft, and the lower surface of the base is an inclined surface, a door with bolts fixed to the lower surfaces of the base and tip of this swing bar, and a swing bar A wedge that is movably inserted in the direction of the swing bar between the inclined surface and the upper surface of the upper frame and that has a flange at the outer end, and an inclination adjustment that fixes the flange of this wedge to the end surface of the base of the swing bar. It is equipped with a bolt.

<Operation> Now, the upper frame is fixed to the lower surface of the base and the tip of the swing bar with bolts, and the door pivotally attached to the lower surface of the slide bar via the rotary shaft provided at the base of the swing bar is Suppose the door is tilted down. At this time, after loosening the bolts that fix the swing bar and the upper frame a little, swing the wedge inserted between the inclined surface of the lower surface of the base of the swing bar and the upper surface of the upper frame, and swing it with the flange of the outer end of the wedge. Tighten the tilt adjusting bolts that fix the end face of the base of the bar, and move the swing bar a predetermined amount in the tip direction. Then, the gap between the inclined surface and the upper surface of the upper frame widens,
The upper frame of the door is tilted in a direction in which the above-mentioned tilt is corrected so that the door end side is raised with the bolt on the swing bar tip side as a fulcrum. Then tighten the bolts that secure the swing bar and the upper frame. In this way, the upper frame of the door is tilted in the opposite direction with respect to the swing bar and is fixed again, whereby the tilt of the door is corrected.

<Embodiment> Hereinafter, the present invention will be described in detail with reference to an illustrated embodiment.

FIG. 1 is a front view showing an embodiment of a supporting device for a slide / swing type door, and 1 is blind (see 31 in FIG. 4).
A slide bar 2 movably provided along the swing bar 2 is rotatably attached to one end of the lower surface of the slide bar 1 via a hinge 3 provided on the base 2a, and the lower surface of the base 2a is an inclined surface 2c. A bar 4 is a door whose upper frame 4a is fixed by two bolts 5 on a base 2a and a tip 2b of the swing bar 2, and 6 is between the inclined surface 2c of the swing bar 2 and the upper surface of the upper frame 4a. A wedge which is movably inserted in the direction of the swing bar and has a flange portion 6a at its outer end, 7 is a tilt adjusting bolt for fixing the flange portion 6a of the wedge 6 to the end surface of the base portion 2a of the swing bar 2, and 8 is the above A door locking device provided between the other end of the lower surface of the slide bar 1 and the other end of the upper frame 4a of the door 4.

Is loosened to make a gap between the swing bar 2 and the upper frame 4a for straightening. Next, tighten the bolt 7 to wedge 6
Is pushed in a predetermined amount toward the tip of the swing bar 2 as shown in FIG. Then, the gap between the inclined surface 2c of the swing bar 2 and the upper surface of the upper frame 4a widens, and the upper frame 4a is corrected in such a direction that the above-mentioned inclination is corrected so that the door tip side is raised with the bolt 5 of the swing bar tip 2b as a fulcrum. Lean. Then swing bar 2
Then, tighten the bolt 5 that fixes the upper frame 4a, and fix the door 4 to the swing bar 2 again. As a result, the front end of the door 4 is raised and the inclination is easily corrected.

In the above embodiment, the base portion 2a and the tip portion of the swing bar 2 are
Since the upper frame 4a of the door 4 is fixed only by the two bolts 5 attached to 2b, it is not necessary to loosen the bolt at the tip when adjusting the tilt, since the bolt at the tip is a fulcrum and only the bolt at the base is fixed. The inclination can be adjusted more easily than before by simply loosening a desired amount and tightening the bolt 7 in the vicinity to move the wedge 6 forward, and the front and rear ends of the upper frame 4a are fixed to the swing bar 2 and partially bent. Because it tilts uniformly without
Accurate tilt adjustment is possible. Also, the head of the bolt 5
Since the 5a fits into the swing bar 2, the appearance of the door 4 is not impaired. Furthermore, since the structure is simple and the number of parts is small compared to the conventional example, the product cost can be reduced and the weight can be reduced, and even if a failure occurs in the wedge part, the vertical frame can be disassembled like the conventional example. Needless to say, there is no need to repair it and it is easy to repair and maintain.

The wedge brim of the present invention does not necessarily have to project to the outer end as in the embodiment, and a simple tapered outer end may be provided with a horizontal screw hole 6b. Needless to say, the present invention is not limited to the illustrated embodiment.

<Effects of the Invention> As is apparent from the above description, in the door supporting device of the present invention, the swing bar is rotatably attached to the lower surface of the slide bar movably provided along the eyes through the rotary shaft. ,
While the upper frame of the door is fixed to the lower surface of the base and the tip of the swing bar with bolts, a wedge having a flange at the outer end is provided between the inclined surface provided on the lower surface of the base of the swing bar and the upper surface of the upper frame. Is movably inserted in the direction of the swing bar, and the end face of the wedge part of the wedge and the base of the swing bar are fixed with the bolts for tilt adjustment. By making a certain amount of gap between the bottom surface of the bar and the top surface of the upper frame, the door that is tilted so that the door tip is lowered can be corrected in the opposite direction with a simpler, lighter, and lower cost structure than before, and the door can be adjusted. It has a remarkable effect that the labor and cost of the work can be significantly reduced as compared with the conventional one.
