Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a door horizontal holding device for a so-called full-open door used as an automatic door for a building or store, for example.

[Conventional technology]

Conventionally, as shown in Figs. 2 to 5, the shoji 32 on both sides are usually fixed, and the central shoji 31 slides left and right to open (if there are two shoji, one is fixed,
A swingable sliding door is known in which the fixed side shoji 32 and the sliding side shoji 31 can be opened inward or outward when the other side is slidable, and when large items are taken in or taken out or in an emergency. In these doors, for example, as shown in Japanese Patent Publication No. 49-43030,
The sliding side shoji 31, which normally serves as a door, is rotatably supported via an axis perpendicular to a hanging frame that slides along a rail above the opening, and applies a predetermined force or more in an out-of-plane direction. It is common that the shaft is disengaged at a portion other than the shaft provided at one end and rotates around the vertical shaft.

However, this type of door has a problem in that the other end of the door tends to sag because the door is supported only at one end of the shaft when the door opens inward or outward.

On the other hand, for example, (a) Utility Model Application Publication No. 59-8472,
There are ideas as seen in (b) Japanese Utility Model Application Publication No. 59-8473, (c) Japanese Utility Model Application Publication No. 59-8474, and (d) Japanese Utility Model Application Publication No. 59-8475. In other words, in the publication (a), the vertical shaft part of the pivot shaft whose upper end is fixed to the hanging frame is inserted into the vertical stile of the door, and a horizontal arm that can freely pivot relative to the pivot shaft is inserted into the upper stile. , a device is proposed in which an inclination adjustment means is provided, such as by using screws or the like to move the upper stile up and down relative to the horizontal arm. In the publication (b), a horizontal arm is fixed to the lower end of a pivot shaft that is rotatably attached to a hanging frame, a wedge is provided between the support plate of the upper stile and the horizontal arm, and this wedge is attached to a long length along the horizontal arm. An idea was shown to adjust the level of the door by sliding it with a bolt. In addition, the publication (c) describes a device in which the horizontal arm installed in the hanging frame is pulled up and down by a vertical bolt that is screwed into the horizontal arm to adjust the horizontal level of the door. It is shown. Furthermore, in Publication (d), a door mounting part that hangs down from the vertical shaft part is rotatably provided inside the vertical stile of the door, and a bolt is installed between this part and a reinforcing stand fixed to the upper stile. An idea is shown in which the horizontality of the door can be adjusted by adjusting the spacing between the two.

[Problem that the invention attempts to solve]

Among the above-mentioned conventional techniques, the devices (a) and (c) are of the type that is tensioned with screws, but the force is concentrated on the screw portion, and the horizontal arm cannot be made long, so uniform support cannot be achieved. In the device (b), it is troublesome to assemble the parts inside the upper stile, and there is a risk that the long bolts may bend and cause support during operation. In addition, in the device (d), large bending and shearing forces are applied to the horizontal bolts installed between the reinforcing table and the door attachment part of the vertical shaft.
Difficult to withstand.

The purpose of this invention is to eliminate the drawbacks of the conventional technology as described above, and to provide a door horizontal holding device that has a simple mechanism, is easy to assemble, is easy to operate, and has excellent load resistance.

[Means to solve the problem]

The door to which the device of this invention is applied is suspended and supported at two or more points, including the hanging shaft 1 inserted into the vertical stile 22 on one side, with respect to the hanging frame 11 that slides along the rail 12 above the opening. , is a type of door that can be rotated around the hanging shaft 1 by applying a predetermined force or more in an out-of-plane direction, and usually slides in the form of a sliding door,
It can be opened inward or outward when loading and unloading luggage or in emergencies.

In this invention, an arm 2 that is rotatable around the hanging shaft 1 is inserted into the upper stile 21 of the door 20, and the inclination of the door 20 with respect to the arm 2 is adjusted to the upper wall position of the upper stile 21 of the door 20. a horizontal adjustment screw 3 whose lower end is in contact with the upper end of the arm 2;
It can be adjusted by the amount of push.

Furthermore, a connecting fitting 4 is provided to connect the tip of the arm 2 and the other vertical stile 23.
One end of the connecting fitting 4 is rotatably connected to the tip of the arm 2 via a pin 5 or the like, and the other end is fixed under tension to the vertical frame 23 by cutting a screw 4a and tightening it with a nut 7. The vertical frames 22 and 23 on both sides are integrally connected via the arm 2 and the connecting fitting 4.

[Effect]

In the device of this invention, in the above-mentioned configuration, the hanging shaft 1
Considering that the arm 2 is a substantially rigid body, when the horizontal adjustment screw 3 is rotated in the pushing direction,
The upper stile 21 is relatively pushed upward, and the entire door 20 (particularly the end opposite to the hanging shaft 1) is lifted up.
Conversely, when the horizontal adjustment screw 3 is rotated in the pulling direction, the upper stile 21 is relatively lowered by the weight of the door, causing the door 20 to lower.

In addition, in the device of this invention, by connecting the tip of the horizontal arm 2 and the vertical stile 23 in a tensioned state with the connecting metal fitting 4, the vertical frames 22 and 23 on both sides are connected via the arm 2 and the connecting metal fitting 4, The integrity of the door 20 and the arm 2 is enhanced.

〔Example〕

The illustrated embodiment will be described below.

FIG. 1 shows the structure of the door horizontal holding device of this invention, in which the main body of the door 20 is suspended from a hanging frame 11 at two points and slides along a rail 12. The hanging frame 11 is made of a member with a hollow rectangular cross section, and roller mounting portions 13a for mounting the rollers 13 are provided at two locations above both ends. A hanging frame 11 is provided on the side that becomes the axis for opening the door 20 inward or outward.
The upper end of the hanging shaft 1 is fixed to the door, and the lower end of the hanging shaft 1 is suspended inside the vertical stile 22 of the door 20. On the other side of the hanging frame 11, a support piece 14 having a folded engagement part 15 that can be freely engaged and detached from inside the upper stile 21 of the door 20 is suspended. In this embodiment, the hanging shaft 1 is fixed to the hanging frame 11 using a bearing member 16 inserted into the hanging frame 11.

An arm 2 rotatable with respect to the hanging shaft 1 is pivotally attached to the hanging shaft 1, and the arm 2 is inserted into the upper stile 21 of the door 20. On the other hand, a back plate 21a having a screw hole is attached to the upper end position of the upper stile 21, and a horizontal adjustment screw 3 screwed into this back plate 21a.
The lower end of the horizontal adjustment screw 3 is in contact with the upper end of the arm 2, and the horizontal adjustment screw 3 transmits a part of the supporting force of the arm 2 to the entire door 20 via the upper wall of the upper stile 21. As described above, by pushing in this horizontal adjustment screw 3, the door 20 is lifted upward, and by returning it, the door 20 is lowered downward.

Further, a pin 5 extending out of the plane of the door 20 is attached to the tip of the arm 2, and a ring-shaped locking part 6 provided at one end of the rod-shaped connecting fitting 4 is rotatably locked to this pin 5. , a screw 4a is attached to the other end of the connecting fitting 4.
