Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to the opening/closing structure of a door such as a sliding door, and more specifically, the present invention relates to an opening/closing structure for a door such as a sliding door. This invention relates to a technology that increases the ease of use by rotating the device and also simplifies the configuration for doing so.

[Background Art] Conventionally, a door such as a sliding door that runs on the upper rail only runs on the upper rail, and its function is a single function. The door cannot be opened and rotated approximately perpendicularly to the upper rail in the vicinity of the door, making it inconvenient to use such a door as a partition. Therefore,
Various configurations have been proposed in which a door such as a sliding door is opened and rotated so as to be substantially perpendicular to the upper rail in its closed position, but this poses a problem when the structure becomes complicated.

[Purpose of the invention] The present invention was made in view of the above problem, and its purpose is to open a door such as a sliding door so that it is approximately perpendicular to the upper rail in the closed position. It is an object of the present invention to provide a door opening/closing structure that can be constructed relatively simply while increasing its ease of use by rotating.

[Disclosure of the invention] The door opening/closing structure of the invention runs the door main body 3 via upper and lower running tools a at least on the door end side along an upper rail 1 which is open at the bottom and has a substantially inverted U-shaped cross section. A retractable receiver 4 is provided, which can be freely configured and retracted to determine the closing position by which the tip of the door body 3 that is opened and closed by running along the upper rail 1 comes into contact with it, and the closing position of the door body 3 is closed. The door main body 3 is configured to be able to freely travel to the inner part beyond the direction of construction, and the upper and lower running tools a, a of the door tip of the door main body 3 are held in this inner part, and the door main body 3 is moved to the upper rail 1.
An opening rotation holding means 6 is provided to allow the door to open and rotate approximately perpendicularly to the door. A cutout b for approximately one piece of the door body 3 for allowing the door body 3 to escape from the upper rail 1
is characterized in that it is provided on the upper rail 1, and by configuring it in this way, the above object is achieved. That is, the receiver 4 that determines the closed position of the door body 3 is retracted, the door body 3 is moved to the back, and the opening rotation holding means 6 provided in the back is used to open the door tip of the door body 3. By holding the upper and lower running tools a and a and rotating the door body 3 through the notch b of approximately one piece of the door body 3 of the upper rail 1 to escape, the door body 3 can be moved against the upper rail 1. Although it is possible to open and rotate almost orthogonally and increase the usability of a door such as a sliding door, it makes effective use of the running tools a, a at the door tip, and when the door body 3 opens and rotates. , a notch a for escape from the upper rail 1
A simple configuration of providing the upper rail 1 is sufficient.

Embodiments of the present invention will be described in detail below based on the drawings.

FIG. 1 shows a schematic front view, in which a plurality of doors 7, 7 are installed on the upper rail 1 and the lower rail 2 so as to be freely movable, but the number of doors 7 may be many or one. Two guide grooves 8 are formed in each of the upper rail 1 and the lower rail 2. Running shafts 5, 5 as running tools a forward in the closing direction are protruded from the upper and lower ends of the door tip side of the door body 3, and the lower running shaft 5 is inserted into the guide groove 8 of the lower rail 2 as a pivot 5a. It is fitted in such a way that it can be moved freely. Runner rollers 9 are rotatably provided on the upper running shaft 5 via a running block, and these runner rollers 9 are mounted on the receiving surface of the upper rail 1 so that they can run. Travel receiving pieces 11, 11 are hung over the entire length on the front and back sides of the upper rail 1 so as to be able to guide travel.

The vertical frame 13, which is an example of the receiver 4 that determines the closing position of the door body 3 built so that the door body 3 can move freely in this way, is rotatably pivoted via a hinge 14. The frame 13 is made retractable from the running part of the door body 3. And it is made to be able to run freely to the part where the vertical frame 13 is evacuated, that is, to the inner part beyond the closed position of the door body 3 in the closing direction. In this deep part is a catch 1 as an example of the opening rotation holding means 6.
6 is provided above, and the running shaft 5 on the door body 3 that has been run to the back is fitted and held in the catch 16. By holding the running shaft 5 in this way, the door body 3 can be moved up and down. It is designed to be able to open and rotate approximately perpendicular to the rails 1 and 2. In such a case, the pivot 5a rotatably provided at the lower end of the lower running shaft 5 is non-rotatably engaged with the guide groove 8 of the lower rail 2, and the tip of the pivot 5a is connected to the vertical frame 1.
3 is evacuated and its position is determined by abutting against the wall surface, and the door is in a state similar to that of holding the lower running shaft 5. In this way, the upper and lower running shafts 5, 5 are held and the door is closed. 7 can be stably opened and rotated.

A notch b corresponding to approximately one piece of the door body 3 is provided in the traveling receiving piece 11 on the vertical frame 13 side of the upper rail 1.
The width W of the receiver 4 and the width B where the door 7 overlaps the traveling receiver piece 11 are made approximately equal.

In this way, by forming the notch b in the upper rail 1 in approximately one piece of the door body 3, the door body 3 can be rotated and escaped so that the door body 3 is approximately orthogonal to the upper rail 1. A notch a that allows the door body 3 to open and rotate to increase the usability of a door such as a sliding door, makes effective use of the running tools a and a at the door tip, and allows the door body 3 to escape from the upper rail 1 when the door body 3 opens and rotates. A simple configuration of providing the upper rail 1 on the upper rail 1 is sufficient.

As shown in FIG. 3, the traveling receiving piece 11 that serves as a partition in the center of the width direction of the upper rail 1 is also formed with a notch b, so that the door 7 on the back side can also be opened and rotated. However, by forming the notch b in this way, there is a risk that the door tip may hit the tip of the notch b during normal running of the doors 7, 7. A guide 18 that projects in an arc shape only on one side 11 is attached to the traveling support piece 11 on the side where the notch b is formed, and a guide 18 that projects in an arc shape on both sides is attached to the end of the travel support piece 11 that serves as an intermediate partition. A guide body 19 is attached so that each door 7 can run smoothly.

FIG. 8 shows the lower structure of the door 7, in which a substantially roll-shaped running roller 20 is provided on the bottom surface of the end opposite to the running shaft 5 and is biased to protrude by a spring 21. is inserted into the guide groove 8 of the lower rail 2 so as to be able to escape, and a door roller 22 is provided near the running roller 20, and this door roller 22 is mounted on the lower rail 2 so as to be able to roll freely. It is designed so that the vehicle can run stably. A mohair 23 is attached between the door wheel 22 and the running shaft 5 on the lower surface of the door 7 to prevent a gap. The mohair 23 is prevented from being strongly rubbed against the floor by the door wheel 22 and the running rollers 20 when the door 7 is rotated and opened.

And at the meeting place of doors 7 and 7,
As shown in FIG. 9a, an elastic packing 25 having mohair 23 and forming a hollow part 24 is attached to the end face of one door 7, and the other door 7
A packing 26 having a hollow part 24 is attached to the end face of the mohair 23.
It is designed to be airtight. In order to make the joint area airtight in this way, the sealing material 27 may be secured with screws as shown in FIG. 9b.

10 and 11 show another embodiment of the same as above, in which the above-mentioned notch b is formed on the surface side of the upper end of the door 7.
Attach the cover plate 31 that closes the notch b to the cover plate 3 as shown in FIG. 11 when the door 7 is closed.
1 to enhance the appearance, and this lid plate 31
protrudes from the rear end of the door 7 by an amount corresponding to the width W of the vertical frame 13, and by positioning this protruding portion 31a on the inner side of the running support piece 11 of the upper rail 1, the door 7 can be placed within the notch b. It is designed to prevent it from opening and rotating unexpectedly.

FIG. 12 shows another embodiment, in which a cover plate 31 that closes the notch b is rotatably pivoted at the upper line so that it hangs down under its own weight, and when the door 7 is opened, the curtain is opened. It is designed so that it can be lifted and rotated like this.

FIGS. 13a, b, and c show still another embodiment, in which doors 7, 7 are provided at both ends of the opening, respectively, so that they can be opened and rotated, and these doors 7, 7 butt in the closed state. This figure shows the packing structure for sealing the parts.

FIGS. 14 and 15 show still another embodiment, in which the width of the notch b is made sufficiently wide so that the door body 3 on the back side can be easily opened and rotated, while the front side This prevents the door body 3 from opening and rotating unexpectedly. In other words, notch b
The width of the upper rail 1 on the back side is as shown in Figure 14.
It is made wide enough so that the door body 3 built in the door can escape. If the notch b is made wide enough to allow the door body 3 on the back side to escape, there is a risk that the door body 3 on the front side will open unexpectedly and rotate. This is prevented by a configuration like this.

That is, a slide arm 42 having a U-shaped cross section is attached to the upper end of the door body 3 built into the upper rail 1 on the front side, and is slidable within the range of the elongated hole 43 using a stopper screw 44 inserted into the elongated hole 43. A locking protrusion 57 protruding from the front and back sides of the door body 3 is attached to this slide arm 42 with a screw 45, and the locking protrusion 57 is attached by biasing the slide arm 42 toward the door edge side with a spring 59. It is pulled towards the door. In this case, the locking protrusion 57 is inserted into the recess 46 at the upper rear end of the door body 3. A locking holder 58 is attached to the edge of the notch b of the upper rail 1 with screws. However, as shown in Figure 14a,
When the door body 3 having the locking protrusion 57 comes into contact with the receiver 4, the locking protrusion 57 is locked by the locking receiver 58 and pulled out against the spring 59, preventing movement in the elongated hole 43. There will be almost no stroke. In this way, the locking protrusion 57 is locked to the locking receiver 58, and the opening rotation of the front door body 3 is reliably prevented. Next, after removing the receiver 4 as shown in Fig. 14b, the door body 3 on the front side is pushed into the area where the receiver 4 was evacuated, and the movement stroke has already been lost. The slide arm 42 is moved together with the door body 3, and this movement causes the locking protrusion 57 to disengage from the locking receiver 58. As a result, the slide arm 42 is pulled toward the door edge by the spring 59, and is locked. The protrusion 57 comes into contact with the door body 3, and the substantial length of the door body 3 is shortened, allowing it to escape from the notch b and opening and rotating easily.

In addition, in the embodiment, the receiver 4 is used as the vertical frame 13, but the receiver 4 does not have to extend along the entire length in the vertical direction of the door body 3 like the vertical frame 13, and may be short. It may be provided within the upper rail 1 and lower rail 2, and its configuration can be modified in various ways.

Further, in the embodiment, the opening rotation holding means 6 holds the running shaft 5 by inserting it into the substantially C-shaped catch 16, but the running shaft 5 may be held from the end thereof. The lower traveling shaft 5 may also be held like the upper traveling shaft 5.

Further, in the embodiment, the receiver 4 is rotated and retracted, but the retracting may also be performed by sliding.

[Effects of the invention] In summary, the present invention is such that the door body is configured to be able to run freely along an upper rail that is open at the bottom and has a generally inverted U-shaped cross section, via upper and lower running tools at least on the door edge side. A retractable receiver is provided to determine the closing position when the tip of the door body, which is opened and closed by running along the rail, comes into contact with the door body. The upper and lower running tools of the door tip of the door body are held in this inner part, and the door body is opened and rotated approximately perpendicularly to the upper rail to open and rotate. A notch for approximately one piece of the door body is provided on the upper rail to allow the door body to escape from the upper rail when the traveling tool is held by the opening rotation holding means and the door body is opened and rotated. Since the receiver that determines the closing position of the door body is retracted, the door body is moved to the back, and the opening rotation holding means provided at the back allows the upper and lower parts of the door tip of the door body to be moved up and down. The door body can be opened and rotated approximately perpendicular to the upper rail by holding the running tool and rotating the door body through the approximately one-piece notch in the upper rail. The idea is to increase the usability of doors such as sliding doors, while also making effective use of the running gear at the door tip, and providing a notch in the top rail that allows the door to escape from the top rail when the door rotates to open. It has the advantage of requiring a simple configuration.
