Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a device for pulling and preventing rotation of a shoji in a swingable door used as an automatic door for a building or store, for example.

[Conventional technology]

Conventionally, in an automatic door as shown in Fig. 3, 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). 2. Description of the Related Art A swingable sliding door is known in which a fixed side shoji 2 and a sliding side shoji 1 can be opened inward or outward in case of taking in or taking out large items 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. 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, and the shoji 1, 2 can be rotated around the rotating shafts 1a, 2a.

By the way, such doors are usually easily rotated to prevent them from opening when a large opening is required or in an emergency. Therefore, the fixed side shoji 2
must be locked or secured in some other way, but if they are locked, they will have to be unlocked even in an emergency, so they are of no use.

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. 4 to 6, the above device has a locking fitting 21, such as an angle-shaped locking fitting, attached to the joining part of the rotating end of the fixed-side shoji 2 and the rotating shaft 1a side of the sliding-side shoji 1. , 21 are provided, and even if an attempt is made to rotate the fixed side shoji 2 when the automatic door is closed, the locking fittings 21, 21 will engage with each other, preventing the rotation and locking. By providing a certain distance 22 between the metal fittings 21, 21, when the sliding side shoji 1 is rotated, the locking metal fittings 21, 21 can be rotated to open and close without interfering with each other. be.

[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 idea solves the problems mentioned above. When the sliding side shoji is closed, only the fixed side shoji can be prevented from opening and closing, and the shoji can be drawn together to create a watertight structure. The purpose of the present invention is to provide a device for pulling and preventing rotation of a shoji screen, which can improve airtightness and 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. 4), 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 the stile 1b of the sliding side shoji 1 and the joining stile of the fixed side shoji 2. A pair of locking tools 3 that can be engaged with each other are attached to opposing surfaces of 2b.

This locking tool 3 consists of a base 4 fixed to the joining frames 1b, 2b, and a drawing piece 5 that projects from the base 4 in a hook shape and forms a tapered surface 6 that draws each other together in the engaged state. The base portion 4 is formed with a recess 7 in which the pulling piece 5 of the other locking member 3 can rotate and slide when the sliding-side shoji 1 rotates around the rotation axis 1a.

By attaching an airtight material 9 to one of the opposing surfaces of the joining stile 1b of the sliding side shoji 1 and the joining stile 2b of the fixed side shoji 2, the airtight material 9 is crimped to prevent damage at the joining part when pulling. Watertightness, airtightness, and soundproofing properties can be ensured.

Furthermore, the locking tools 3 can be provided at a plurality of locations in the longitudinal direction of the stile 1b, 2b, for example, at the top and bottom, or at the top, center, and bottom.

[Effect]

Normally, when the sliding side shoji 1 is closed, the pulling pieces 5 of the locking tools 3 of the matching frames 1b and 2b engage with each other, and the shoji 1 and 2 are pulled together along the tapered surface 6, creating an airtight seal. Crimp material 9.

In this state, even if a force is applied to open and close the fixed-side shoji 2 around the rotating shaft 2a, the fixed-side shoji 2 will not open due to the engagement of the locking tools 3.
However, when a force is applied to rotate the sliding shoji 1 around the rotating shaft 1a, the pulling piece of the locking tool 3 rotates and slides within the recess 7 of the other locking tool 3, and the engagement is interrupted. It is released and both shoji 1 and 2 can be opened and closed.

Moreover, since the locking tools 3 are not engaged with each other when the sliding-side shoji 1 is not closed, they can be opened and closed by a force in an out-of-plane direction.

〔Example〕

FIG. 1 shows a cross section of the shoji pulling and rotation prevention device of this invention, in which the notch holes 11 are provided in the opposing surfaces of the mating frames 1b and 2b of the sliding shoji 1 and the fixed shoji 2. The locking tool 3 is fitted into the locking tool 3, and fixing pieces 8 formed on both sides of the base 4 of the locking tool 3 are fixed with screws (not shown) or the like. This figure shows the drawn state, in which the tapered surfaces 6 of the hook-shaped drawing pieces 5 that protrude from the base 4 are in contact with each other, and both the shoji 1 and 2 are in contact with each other.
are attracted to each other. Further, an airtight material 9 is attached to the connecting frame 2b of the fixed side shoji 2 in the longitudinal direction, and is pressed between the connecting frames 1b and 2b.

A recess 7 recessed inwardly is formed in the base 4 of the locking tool 3, and the pulling piece 5 is detached while rotating within the recess 7.

Moreover, 12 in the figure is a glass plate.

FIG. 2 shows a locking tool 3 attached to a fixed side shoji 2 in another embodiment. In this embodiment, a continuous piece 10 that connects the base 4 and the pulling piece 5 is formed on the upper surface of the locking tool 3, reinforcing the locking tool 3,
The pulling piece 5 is designed to be difficult to damage. In this case, a connecting piece 10 is provided on the lower surface side of the locking tool 3 attached to the sliding shoji 1.

In addition, by making the outer surface of the pulling piece 5 of the locking tool 3 and the inner surface of the recess 7 into an arcuate curved surface, when the sliding side shoji 1 is opened and closed from the engaged state, the locking tools 3 Engagement can be smoothly disengaged with little interference.

Note that synthetic resin, metal, or the like can be used as the material for the locking tool 3.

[Effect of idea]

The shoji pulling and rotation prevention device of this invention can prevent only the fixed side shoji from being opened and closed by engaging the pulling pieces of the locking tool when the sliding side shoji is closed. In addition, the sliding side shoji can be opened and closed together with the fixed side shoji by applying force in an out-of-plane direction even from the engaged state, so that it can be used in an emergency.

Further, since the fasteners are drawn together by the tapered surface of the drawing piece, the watertightness, airtightness, and soundproofing properties of the joining part can be improved.
