Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a device for pulling in and preventing the rotation of a shoji in a 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, in an automatic door as shown in Fig. 5, the shoji 2 on both sides are normally fixed, and the central shoji 1 slides left and right to open (if there are two shojis, one is fixed and the other slides). A rotatable sliding door is known in which a fixed side shoji 2 and a sliding side shoji 1 can be opened inward or outward when large items are taken in or taken out or in an emergency. these are,
The sliding side shoji 1 is suspended and supported by a hanging frame that slides along a rail above the opening, and a force exceeding a predetermined value is applied to each shoji 1 and 2 on the sliding side and the fixed side in an out-of-plane direction. Generally, when the shoji 1, 2 is applied, the parts other than the rotating shafts 1a, 2a provided at one end of the shoji 1, 2 are disengaged, allowing the sliding doors to pivot around the rotating shafts 1a, 2a.

Incidentally, such a door is normally made so that it cannot be easily swiveled open except when a large opening is required or in an emergency. Therefore, the fixed side shoji 2 must be locked or fixed by some other method, but if it is locked, it will be useless because it will need to be unlocked even in an emergency.

An example of a device that deals with this problem is the device disclosed in Japanese Patent Application Laid-open No. 150681/1983. As shown in FIGS. 6 to 8, the above device includes a locking fitting 21 in the form of an angle, etc., at the meeting point between the swing side end of the fixed side shoji 2 and the rotating shaft 1a side of the sliding side shoji 1. 21 is provided, and even if an attempt is made to turn the fixed side shoji 2 with the automatic door closed, the locking fittings 21, 21 will engage with each other to prevent the turning, and the locking fittings 21, By providing a certain distance 22 between the locking fittings 21, 21, when the sliding-side shoji 1 is turned, the locking fittings 21, 21 can be turned open and closed without interfering with each other.

[Problem that the invention attempts to solve]

However, in conventional automatic doors, including the above-mentioned devices, there is a gap between the sliding side shoji 1 and the fixed side shoji 2, which results in poor watertightness and airtightness, and poor soundproofing performance. .

This invention solves the above-mentioned problems. When the sliding side shoji is closed, only the fixed side shoji can be prevented from swinging open and closed, and the shoji can be drawn together to create watertightness. The object of the present invention is to provide a device for pulling and preventing the rotation of shoji screens, which can improve airtightness.

[Means for solving problems]

The device of this invention has a sliding side shoji 1 that can slide within a window frame and a fixed side shoji 2 that is normally fixed within the window frame, the sliding side shoji 1 and the fixed side shoji 2.
are the rotating shafts 1a and 2a at one end (conventional example No. 6), respectively.
This is a device for pulling and preventing rotation of a shoji in a door that can be rotated to open and close around the sliding shoji 1, and a stile 1b for the sliding shoji 1 and a stile 2b for the fixed shoji 2. A first locking tool 3 and a second locking tool 8 that can be engaged with each other are attached to opposing surfaces of.

The first locking tool 3 consists of a plate-shaped base 4 and a hook piece 5 bent from the base 4 into a hook shape with the tip facing inward in the shoji plane. Fix it to the stile.

The second locking tool 8 has a plate-shaped base 9 and a vertical locking shaft 10 with a circular cross section.
A guide for guiding and locking the tip of the hook piece 5 of the first locking tool 3 between the base 9 and the base 9, supported by upper and lower support pieces 11 protruding from the base 9 at a predetermined interval. A groove 12 is formed. The second locking tool 8 is also fixed with screws or the like at a position facing the matching stile of the other shoji.

By making the locking shaft 10 circular in cross section, when the first locking tool 3 and the second locking tool 8 are engaged, that is, the sliding side shoji 1 is slid in the horizontal direction and is attempted to be closed. In this case, the tip of the hook 5 of the first locking tool 3 is connected to the second locking tool 8.
It comes into contact with the locking shaft 10 , slides along its outer peripheral surface in the shoji drawing direction, and is housed in the guide groove 12 .

Moreover, when the sliding side shoji 1 is rotated around the rotating shaft 1a from the engaged state, the hook piece 5 and the locking shaft 10 which were in the engaged state rotate relative to each other, and the engagement is stopped. It's starting to come off.

That is, the hook piece 5 and the locking shaft 10 are connected to the sliding side shoji 1.
It is possible to engage and disengage freely in the sliding direction of the shoji 1 and around the rotation axis 1a of the sliding shoji 1.

In addition, the first locking tool 3 and the second locking tool 8 are fixed to the matching frame 1b of the sliding-side shoji 1 depending on the positional relationship and rotation direction of the sliding-side shoji 1 and the fixed-side shoji 2. It is determined to which side frame 2b of the side shoji 2 it will be attached. Furthermore, these first locking devices 3 and second locking devices 8 are usually attached at multiple locations in the longitudinal direction of the joining frames 1b, 2b, such as upper and lower, upper and lower, central, and lower portions.

Moreover, by attaching the airtight material 14 to one or both of the joining frames 1b and 2b, watertightness, airtightness, and soundproofing properties can be ensured in the drawn state.

〔Example〕

Next, the illustrated embodiment will be described.

FIGS. 3A, 3B, and 3C show an example of the first locking tool 3, in which a hook piece 5 bent into a hook shape protrudes from a plate-shaped base 4. In the figure, 7 is a screw hole for fixing the shoji to the stile. Further, a tapered surface 6 is formed at the tip of the hook piece 5, and a second locking tool 8
The locking shaft 10 is pulled together smoothly.

4a, b, and c show an example of the second locking tool 8, which is supported by a plate-shaped base 9, upper and lower support pieces 11 protruding from the base 9, and support pieces 11. It consists of a locking shaft 10 with a circular cross section forming a guide groove 12 between the locking shaft 10 and a screw hole 13 for fixing with a screw.

1 and 2 show how these locking tools 3 and 8 are attached. In this example, the first locking tool 3 is attached to the connecting frame 1bb of the sliding side shoji 1, and the second locking tool 3 is attached to the connecting frame 1bb of the sliding side shoji 1. A stopper 8 is attached to the matching frame 2b of the fixed side shoji 2.

In addition, 16 in the figure is a glass plate, and 16 is a matching frame.
An airtight material 14 is attached in the longitudinal direction of b and 2b.

Fig. 1 shows the situation when the sliding side shoji is closed by normal lateral sliding. The tip of the piece 5 comes into contact with the locking shaft 10 of the second locking tool 8, and is guided by the outer peripheral surface of the locking shaft 10 and fitted into the guide groove 12 while sliding. In addition, when the shoji is pulled in at this time, the tip of the fin-like part of the airtight material 14 is caused to protrude from the facing frame 1b, 2b by the contact piece 1.
5 and can maintain airtightness and watertightness.

In this state, since the hook piece 5 and the locking shaft 10 are engaged with each other, the fixed side shoji 2 is moved to the rotating shaft 10.
a (See Figure 6) The fixed side shoji does not open even if a force is applied to turn it.

However, as shown in FIG. 2, when a force is applied to rotate the sliding shoji 1 around the rotating shaft 1a, the hooks 5 move on the outer periphery of the locking shaft 10 around the rotating shaft 1a. However, the engagement is easily released, and both the shoji 1 and 2 can be turned.

Furthermore, when the sliding-side shoji 1 is not closed, the first locking tool 3 and the second locking tool 8 are not engaged, so that they can be pivoted to open and close by a force in an out-of-plane direction.

The embodiment shown in FIGS. 1 and 2 is for the case where the sliding shoji 1 is located on the outdoor side of the fixed shoji 2 and opens inward when pivoting to open and close, as shown in FIG. In the case of opening, it is necessary to attach the first locking tool 3 to the matching stile 2b of the fixed-side shoji 2, and the second locking tool 8 to the matching stile 1b of the sliding-side shoji 1. Moreover, when the sliding side shoji 1 is on the indoor side of the fixed side shoji 2, the situation is reversed.

Further, in this embodiment, the airtight member 14 is provided with an extending portion 14a to prevent the members from directly colliding with each other even when the sliding shoji 1 is rotated as shown in FIG.

Note that synthetic resin, metal, or the like can be used as the material for the fasteners 3 and 8.

[Effect of idea]

The shoji pulling/rotation prevention device of this invention prevents only the fixed side shoji from swinging open and closed by the engagement of the first locking tool and the second locking tool when the sliding side shoji is closed. Moreover, even from the engaged state, the sliding side shoji can be pivoted to open and close together with the fixed side shoji by applying force in an out-of-plane direction, making it possible to respond to emergencies.

Furthermore, due to the engagement of the first locking tool and the second locking tool,
Since the joining stile of the sliding side shoji and the joining stile of the fixed side shoji are drawn toward each other, watertightness, airtightness, and soundproofing properties in the joining part can be improved.
