Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sliding door opening device that can open and close a frontage by reciprocating the door body or turning it horizontally.

Various doors of this type have been proposed in the past.

For example, the one proposed in Japanese Patent Publication No. 130 (Japanese Patent Publication No. 130), as shown in FIG. ]02 and fit the door body A into this frame body 102,
One end thereof was supported on the frame 102 by vertical and phantom bearing mechanisms 103 and 104 so as to be horizontally rotatable. However, according to this, when the width of the door body A is wide or when the weight of the door body A is heavy, the frame body 102
When a large rotational load is applied to the door body 102, the frame body 102 is deformed as shown by the broken line in the figure, and the free end of the door body A hangs down, making it impossible to open and close the door body A smoothly. In order to solve this problem, the amount of deformation of the frame 102 due to the rotational load is considered in advance, and when the frame 102 is deformed due to the weight of the corpse A being added to the frame 102, the door body A is free. It is conceivable to use a frame 102 having a shape that prevents the ends from sagging. For example, the second
1! As shown in I, the upper corner angle θ of the frame 102 is set to an angle of 90 degrees or less, and when ff1it of the door body (not shown) is added to this frame 102, the corner angle θ becomes 90 degrees. It is possible to do so. However, since the amount of deformation of the frame differs depending on the weight and width of the door, in order to adopt the two-part method, it is necessary to change the above corner angle θ depending on the weight and width of the door. This method requires the preparation of a frame body with a 100% diameter, which has the disadvantage of making it unsuitable for mass production.

In addition, as shown in FIG. 3, the system proposed in Japanese Patent Application Laid-open No. 58-65886 has a traveling mechanism 2 that travels back and forth.
One end of the door A is attached to the upper end of the door A by a bearing mechanism 202 so that it can rotate horizontally, and a support rod 203 that prevents the free end of the door A from drooping is connected to the upper end of the door A and the traveling mechanism 20.
It was constructed between 1 and 1. However, according to this, it is necessary to use a support rod 203 with extremely high bending strength. There is a need for an increase in storage space,
There is a drawback that prices are forced to rise.

The present invention has been made to improve the above-mentioned drawbacks.
To provide a sliding door with a simple structure that allows proper installation by on-site adjustment even for door bodies of different weights and widths.

The technical means to achieve the two-legged objective is to support one end of the door body, which is reciprocated and opened and closed by the forward and reverse movement of the traveling mechanism, on a bearing cock attached to the traveling mechanism so that it can rotate horizontally. A frame body is fixed to the bearing block, and an inclined position opening joint structure is provided between the frame body and the traveling mechanism for finely displacing the frame body in the vertical direction.

For example, if the free end of the door body is drooping and the lower surface of the door body is in contact with the floor, etc., making horizontal rotation of the door body impossible, the tilt position adjustment mechanism The sagging can be adjusted by tilting (lifting) the door upward, thereby moving the door body around 1 so that it becomes horizontal. Therefore, the hanging of the door body can be adjusted freely depending on the type of door at the site, such as when the weight of the door body is heavy or the width of the door body is wide.

An embodiment of the present invention will be described below with reference to FIGS. 4 to 11.

The sliding door l shown in Fig. 4 has a width of the frontage,

Next, a flange 19 integrally provided with a vertical support shaft 18 on the upper surface of one end of the door body A shown in FIG. 5 is fixed by a mounting pole 1-20, which is also shown in FIG. ,J.
The support shaft 18 is inserted into the bush 7 of the above-mentioned bearing block 1 cock 8, and the saw washer 22 is fixed to the upper surface of this support shaft 8 by the pole 1-21, and the saw washer 22 is inserted into the bush 7 of the bearing block 1 cock 8. It is locked in the pulling direction of 18. Further, a guide rail 23 is attached to the lower surface of one end of the door body A so as to be located coaxially with the support shaft 18, and this guide IJ-ra 23 is attached to the guide rail 24.
'r' does not cause sideways movement (it is locked so that it can run).

On the other hand, as shown in FIG. 7, between the upper surface of the free end of the door body A and the double door hanger holder 12, there is a groove for positioning and holding the door body A in a horizontal proper position. A positioning holder 25 is interposed.

That is, this positioning holder 25 is a
It consists of a lower pair of U-shaped engagement fittings 25a and 25b, of which the upper engagement fitting 25a is connected to the door handle bracket 12.
The lower engaging fitting 25b is fixed to the door body A side by a bolt 26b, while the lower engaging fitting 25b is fixed to the door body A side by a bolt 26b.

In addition, as shown in FIG. 5, decorative plates 27 and 28a are formed along the lower edge of the frame 6 and the upper and lower edges of the door body A.

28b is installed to improve its appearance.

On the other hand, as is clear from FIG. 5, the door body B described in FIG. On the other hand, a pair of latches 28a and 28b under -L are provided at the other end.
Latch receivers 2 are placed at the top and bottom of the frontage 2 corresponding to 8a and 28b.
9a and 29b are provided. When the door body B is in the closed position, the latches 28a and 28b are moved to the latch receivers 29a and 2.
When 9bG is set, the door body B will not open even if it receives an external force such as a breeze.

In addition, in FIG. 5, 30 is an example of a drive device for making the traveling mechanism 5 run in forward and reverse directions, and a drive wheel 32 and a driven wheel 33 connected to a drive source 31 are installed, and these drive wheels 32 The connecting portion 4A34 is wound between the driven wheel 33 and the driven wheel 33. Then, the IS is connected to this connecting member 34.
The ahanger 5b is connected, and the driving wheel 32 driven by the driving source 31 is rotated to cause the traveling mechanism 5 to travel from the connecting portion 34 through the door hanger 5b.

According to the sliding door 1 described above, as shown in FIG.
; When the engaging fitting 25b is placed on the top and the two are engaged in the top direction and positioned, the proper posture of the door body A when using the above-mentioned 1A as a sliding door is automatically set. is maintained. Also, from this state, move the door body A to the support shaft 1.
8 (see FIGS. 5 and 6), the lower engaging fitting 25 of the positioning holder 25 will open slightly.
b is released from the engagement base metal fitting 25b, and the free end of the door A hangs down due to the weight of the door A. In other words, the bush 7 of the bearing 1 cock 8 and the support axis 1
There is a slight gap (play) between the support shaft 18 and the frame 6CJ, and since the support shaft 18 and the frame 6CJ are not completely rigid bodies, if a downward rotational load is applied to them due to the weight of the door body A, they will respond to the weight. If the above-mentioned support shaft] 8 is tilted within the bushing 7,
As the support shaft 18 and the frame 6 bend, as a result, the first
As shown in Figure 0, the free end of the door body A hangs down. In this case, the fifth
7, 8, and 9 is operated to tilt the frame 6 vertically at its tip, thereby changing the attitude of the support shaft 18. ζ Set the door body A to an appropriate posture. Specifically, when the bolt 16 is tightened, the tip of the frame 6 rises and the frame 6 is tilted upward, and as a result, the bearing block 8 is tilted together. , the support shaft 18 held by this bearing block 8 is tilted in the same direction, and the free end of the door body A is raised and maintained in an approximately horizontal proper position as shown in FIG. dripping After adjusting the posture in this way, the mounting port 14 is tightened to fix the tip of the frame 6 to the door hanger receiving fitting 12. Conversely, when the 7-knot bolt 16 is loosened, the tip of the frame 6 lowers, so the door body A
The free end of is displaced downward, but this operation is not possible when the lower engagement fitting 25b of the above-mentioned positioning holder 25 is in a diagonal state with respect to the upper engagement fitting 25a. In other words, this is necessary when the free end of the door body A is lifted upward.

In the above case, when the sliding door 1 is used as a sliding door, the right half of the frontage 2 is closed by the door body B, and the door pocket portion 3 is formed by the door body B, as explained in FIG. . Then ζ, the drive device 30 shown in FIG. 5 is started. At this time, when the driving mechanism 5 is moved in the right direction X and \ by the drive device 30, the bipedal door 1 is accommodated in the door compartment 3 shown in FIG. 4, and the left half of the frontage 2 is opened.

Conversely, when the driving mechanism 5 is driven in the left direction Y by the drive device 30, the left half of the frontage 2 is closed.

Next, when the sliding door 1 with a door opening device is used as a hinged door, the door body A is pushed out to the outside of the frontage as shown by arrow Z in FIG. As a result, the upper and lower engaging fittings 25a and 25b of the positioning holder 25 are disengaged, and the door body A is supported only by the support shaft 18 shown in FIGS. 5 and 6, and its free end is drooping, but the amount of drooping is
As described above, the tilt attitude adjustment mechanism 17 is set to such an extent that turning of the door body A is not hindered.

Therefore, due to the above-mentioned pushing, the door body A is pivoted about the support shaft 18 in the -ζ horizontal direction and is opened.

If this operation is performed on the left half of the frontage 2 in FIG. 4, that part will be opened to allow people to pass through. Furthermore, if this is done in the right half of the frontage 2 in Figure 4, the door body B will be opened at the same time as shown by the solid line in Figure 4, so the frontage will be wide open for emergencies and doll cargo. ! Be able to deal with people. In addition, when closing the above-mentioned frontage 2 by rotating the door body A in the horizontal direction to open it, the upper and lower engagement fittings 25a25b of the positioning holder 25 shown in FIG. 7 are engaged, and the door body A is opened. Position it in the closed position.

As described in detail below, according to the sliding door lA with the door opening device according to the present invention, the attitude of the door body can be adjusted in the free position by the operation of the tilt attitude adjustment mechanism. Therefore, it is possible to properly attach various door bodies having different weights and widths. Moreover, the above-mentioned tilt attitude adjustment mechanism can be constructed from a simple member such as one or more poles I. In particular, if the tilt attitude adjustment mechanism is constructed of a port or the like as in the above-described embodiment, there is an advantage that the hanging of the free end of the door can be adjusted steplessly.
