Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a support device for a shoji in a sliding door that can be pivoted to open and close, which is used as an automatic door for a building or store, for example.

[Conventional technology]

Conventionally, as shown in Figures 4 to 7, under normal conditions, the shoji 32 on both sides are fixed, and the central shoji 31 slides left and right to open (if there are two shoji, one is fixed and the other is fixed). A sliding door is known in which the fixed side shoji 32 and the sliding side shoji 31 can be opened inward or outward when taking in and taking out large objects, or in an emergency. . In these doors, the sliding-side shoji 31 is usually suspended at two or more points on a hanging frame that slides along a rail above the opening, and if a predetermined force or more is applied in an out-of-plane direction, one end will break. The most common type is one that is disengaged at a portion other than the hanging shaft and rotates around the hanging shaft.

In addition, in the figure, 33 is a hinge formed by the hanging shaft of the sliding side shoji 31, and 34 is a hinge of the fixed side shoji 32.

In that case, the support device for the engaging part is as follows:
For example, there is one described in Japanese Utility Model Application Publication No. 59-8479.

This device has a hinge formed at one end, and the tip of a support piece with an L-shaped cross section that hangs from a hanging frame can be freely engaged and detached from a U-shaped engagement part provided in an opening formed in the upper part of the other end of the shoji. Furthermore, by a ball or leaf spring, etc., biased by a coil spring,
This is to elastically lock the L-shaped support piece.

In this case, the shoji slides laterally in a state in which the upper plate of the U-shaped engagement portion and the L-shaped support piece are engaged, and the shoji is pivoted to open and close by engaging and disengaging the L-shaped support piece.

[The problem that the idea aims to solve]

By the way, in such a sliding door that can be pivoted to open and close, since it is structurally pivoted around a hanging shaft at one end, the other end tends to hang down when the door is pivoted to open and close.

Therefore, it may be difficult to smoothly engage and disengage the other end engaging portion on the side opposite to the hanging shaft side. In other words, as the other end engaging part side hangs down, a frictional force is generated between the engaging part of the shoji and the tip of the L-shaped support piece, and a large force is required to engage and disengage, so that it cannot be opened in an emergency. It may be difficult to close something that is open at one end, or when you turn it to close something that is open at one end.

Therefore, in conventional support devices, a tapered surface is formed on one or both of the engagement portion of the shoji and the tip of the L-shaped support piece, so that engagement and disengagement can be made as smooth as possible. However, even if a tapered surface is provided, a large frictional force due to sagging acts on the contact surface, so it cannot be said that this is a sufficient improvement.

The purpose of the shoji support device of this invention is to solve the above-mentioned problems.

[Means to solve the problem]

The shoji support device of this invention is suspended and supported by a hanging frame 10 that slides along a rail above the entrance/exit opening, and the other end of the shoji can be opened and closed by rotating around a hanging shaft provided at one end. It is suspended and supported so that it can be freely engaged and detached.

The hanging shaft, which is the axis of rotation opening and closing, connects the hanging frame 10 and the upper part of the shoji 1 in the vertical direction, and is rotatable around the axis relative to the hanging frame 10 or the shoji 1, so that the shoji 1 can be moved horizontally. (corresponds to the hinge 33 of the sliding-side shoji 31 in FIGS. 5 to 7). The configuration of this hinge part is not particularly limited, and for example, a bearing part may be formed on the hanging frame 10 or the shoji 1, or an outer cylinder fixed to the shoji 1 side may be provided on the hanging shaft part.
A structure in which the hanging shaft and the outer cylinder are mutually rotatable is conceivable.

The support structure at the other end of the shoji 1, that is, the end opposite to the hanging shaft, includes a support piece 11 with an L-shaped cross section hanging from the hanging frame 10, and an inverted L-shaped cross section in the opening 4 formed at the top of the shoji 1. It consists of an engaging part 5 having a shape, and a support piece 11
The horizontal piece 11b at the lower end is the horizontal part 5b at the upper end of the engaging part 5.
It is designed to be able to engage and disengage freely. The horizontal piece 11b of these supporting pieces 11 and the horizontal part 5 of the engaging part 5
In the engaged state, the shoji 1 has both upper ends suspended and supported by the hanging frame 10, and slides open and close along the rails together with the hanging frame 10.

The hanging frame 10 is made of a rod-shaped member or the like with a square or hollow square cross section. The cross-sectional shape of the hanging frame 10 and the sliding mechanism via the hanging frame 10 are not particularly limited, and known ones can be used. There is one in which the roller support member is suspended on a rail above the opening, and can be made to travel along the rail in a suspended state.

In addition, the tip of the support piece 11, that is, the horizontal piece 1
One or more guide rails 13 having a horizontal axis are attached to one or both of the distal end of the horizontal part 1b or the distal end of the horizontal part 5b of the engaging part 5 so as to be rotatable around the horizontal axis. Shoji 1
The lower surface of the horizontal part 5b of the engaging part 5 or the support piece 1
The upper surface of the horizontal piece 11b of 1 is the guide roller 1
It is designed to slide along 3. Therefore,
When engaging and disengaging the support piece 11 and the engagement part 5 during swing opening and closing, the guide roller 13 on the support piece 11 side is moved to the horizontal part 5b of the engagement part 5 or the horizontal piece 11 of the support piece 11.
b, and the frictional force between the two is significantly reduced, allowing smooth opening and closing.

〔Example〕

Next, the illustrated embodiments (FIGS. 1 to 3) will be described.

Figures 1 to 3 show the end of the shoji 1 opposite to the hanging shaft. An opening 4 is formed in the upper part of the shoji 1, and an engaging portion with an inverted L-shaped cross section is formed in the opening 4. 5 is provided. In this embodiment, the base portion 5a and the horizontal portion 5
A synthetic resin or metal attachment consisting of b is fixed to the upper frame 2 with screws to form the engaging portion 5.

On the other hand, the support piece 11 having an L-shaped cross section consists of a base piece 11a hanging down from the hanging frame 10 and a horizontal piece 11b bent from the lower end of the base piece 11a. It is fixed and the height can be adjusted slightly up and down.

The horizontal piece 11b of the support piece 11 fits within the opening 4 of the shoji 1 when the shoji 1 slides in the lateral direction, and is held in place by the elastic locking member 6 provided on the horizontal part 5b of the engaging part 5.
It is designed so that it will not become disengaged. That is,
A spherical locking recess 12 is formed on the upper surface of the horizontal piece 11b, and the coil spring 6b of the elastic locking member 6
As a result, the downwardly biased steel ball 6a fits into the locking recess 12, and the engagement between the support piece 11 and the engaging portion 5 is prevented from being disengaged unless a force above a certain level is applied. It's summery.

Two guide rollers 13 are attached to the tip of the horizontal piece 11b of the support piece 11 on both sides so as to avoid the elastic locking member 6, and guide the horizontal part 5b of the engaging part 5 during engagement and disengagement. I'm starting to do that.
Incidentally, tapered surfaces 5c and 11c are formed at the tip of the horizontal portion 5b of the engaging portion 5 and the tip of the horizontal piece 11b of the support piece 11, respectively, to further smooth the sliding movement.

Further, a cushioning material 7 is attached to the base portion 5a of the engaging portion 5 to soften the impact acting on the support piece 11 during engagement and to absorb some manufacturing errors.

In this embodiment, the guide roller 13 is attached only to the tip of the horizontal piece 11b of the support piece 11, but conversely, the guide roller 13 is attached to the tip of the horizontal part 5b of the engaging part 5, and the guide roller 13 is attached to the tip of the horizontal piece 11b of the support piece 11. The horizontal piece 11b may be slid. moreover,
A plurality of guide rollers 13 are provided at the tips of both,
They may also be slid against each other. In that case, it is necessary to shift the mounting positions of the guide rollers 13 vertically so that the upper and lower guide rollers 13 do not collide with each other.

[Effect of idea]

In the shoji support device of this invention, when the supporting piece having an L-shaped cross section and the engaging part having an inverted L-shaped cross-section on the shoji side are engaged and disengaged, the surfaces do not come into direct contact with each other, and the tip of the supporting piece or the engaging part Since the guide roller slides on the horizontal part of the engaging part or the horizontal piece of the support piece, the frictional force is significantly reduced, and even if the shoji sag, smooth opening and closing can be expected.
