Description

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

Various doors of this type have been proposed in the past.
For example, the one proposed in Japanese Patent Publication No. 49-43030, as shown in FIG. The door body A was fitted into this frame body 102, and one end of the door body A was supported by a pair of upper and lower bearing mechanisms 103 and 104 on the frame body 102 so as to be horizontally pivotable. However, according to this, when the width of the door body A is wide or the weight of the door body A is heavy, a large rotational load is applied to the frame body 102, and the frame body 102 deforms as shown by the broken line in the figure. As a result, the free end of the door body A sagged, making it impossible to open and close it 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 weight of the door A is added to the frame 102, the frame 102 is
A frame body 1 having a shape that can prevent the free end of the door body A from hanging down when the frame body A is in a deformed state.
It is possible to use 02. For example, the second
As shown in the figure, the upper corner angle θ of the frame 102 is set to an angle of 90 degrees or less, and when the weight of the door body (not shown) is added to the frame 102, the corner angle θ becomes 90 degrees. It is possible to do so. However, since the amount of deformation of the frame varies depending on the weight and width of the door, in order to take the above-mentioned measures, it is necessary to change the corner angle θ depending on the weight and width of the door.
It is necessary to prepare a frame body with a 100% diameter, which has the drawback that it is unsuitable for mass production.

In addition, as shown in FIG. 3, one end of the door body A is attached to a bearing mechanism 202 on a traveling mechanism 201 that travels back and forth.
A support rod 203 is installed between the upper end of the door A and the traveling mechanism 201 to prevent the free end of the door A from drooping. However, according to this, the support rod 203 needs to have extremely high bending strength, and the attachment structure between the support rod 203 and the door body A or the traveling mechanism 201 needs to be strong. Therefore, there are drawbacks such as an increase in storage space and a rise in price.

The present invention has been made in order to improve the above-mentioned drawbacks, and provides a sliding door with a door opening device that has a simple structure and can be properly installed by on-site adjustment even if the door body has a different weight or width. The purpose is to

Technical means for achieving the above purpose include a traveling mechanism that reciprocates the opening and closing of the door body by running in forward and reverse directions;
A frame body is suspended from the traveling mechanism and extends in a substantially horizontal direction directly above the door body, and one end of the door body is connected to one end of the frame via a support shaft so as to be horizontally pivotable. At the same time, the other end of the door body is removably held at the other end of the frame via a positioning holder, and the frame is provided between the other end of the frame and the traveling mechanism. A tilt attitude adjusting mechanism is provided for tilting and displacing the attitude of the frame body in the vertical direction by changing the suspension position between the other end of the body and the traveling mechanism.

According to this technical means, for example, when the free end of the door body is drooping and the lower surface of the door body is in contact with the floor etc. and the door body cannot be rotated horizontally, the tilting posture adjustment mechanism allows the frame to In other words, the distance between the other end and the traveling mechanism is adjusted, and this position adjustment causes the other end of the frame to tilt upward (lift), thereby making the door horizontal. The hanging can be adjusted by tilting it as shown.
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.

As a result, the free end of the door body A hangs down as shown in FIG. In this case, if the amount of hanging is large and the lower part of the door body A comes into contact with the floor, which may impede the horizontal rotation of the door body A, please refer to Figures 5, 7, 8, and 9. The tilt attitude adjustment mechanism 17 is operated to vertically tilt the frame body 6 at its tip, thereby changing the attitude of the support shaft 18 and setting the door body A to an appropriate attitude. 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 as a unit. 8 is tilted in the same direction, and the free end of the door body A is raised to maintain an approximately horizontal proper position as shown in FIG. After adjusting the posture in this way, remove the mounting bolt 14.
is tightened to fix the tip of the frame 6 to the door hanger holder 12. Conversely, when the bolt 16 is loosened, the tip of the frame 6 is lowered, and the free end of the door A is displaced downward. This is necessary when the door body A is in a floating state with respect to the upper engagement fitting 25a, that is, when the free end of the door body A is floating upward.

In the above case, when the sliding door 1 with the door opening device is used as a sliding door, the right half of the frontage 2 is closed by the door body B as explained in FIG. to form. Then, the drive device 30 shown in FIG. 5 is started. At this time, when the traveling mechanism 5 is driven in the right direction X by the drive device 30, the door 1 is accommodated in the door pocket portion 3 of FIG. 4, and the left half of the frontage 2 is opened.
Conversely, when the driving mechanism 5 moves 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 engagement of the upper and lower engagement fittings 25a and 25b of the positioning holder 25 is released, and the door body A is moved to the support shaft 18 of FIGS. 5 and 6.
The free end of the door body A will be supported by the hinges, and its free end will sag, but the amount of sagging is set by the tilt attitude adjustment mechanism 17 to an extent that does not interfere with the turning of the door body A, as described above. ing.
Therefore, due to the above-mentioned extrusion, the door body A pivots in the horizontal direction about the support shaft 18 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.
In addition, if this is done at the right half of frontage 2 in Figure 4, door body B will also be opened at the same time as shown by the solid line in Figure 4, so the frontage will be wide open and can be used in emergencies or for carrying in large cargo. become. In addition, when closing the above-mentioned frontage 2 by horizontally turning the door body A to open it, the upper and lower engaging fittings 25a and 25b of the positioning holder 25 shown in FIG. 7 are engaged, and the door body Position A in the closed position.

As described in detail above, according to the sliding door with a door opening device according to the present invention, the attitude of the door body can be freely adjusted on site by the operation of the tilt attitude adjustment mechanism. Therefore, it is possible to properly attach various door bodies having different weights and widths. Furthermore, the tilt attitude adjustment mechanism can be constructed from a simple member such as one or more bolts. especially,
If the tilt attitude adjustment mechanism is constructed using bolts or the like as in the above embodiment, there is an advantage that the droop of the free end of the door can be adjusted steplessly.
