JP2513215Y2 - Locking device for opening and closing shoji - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a locking device for an opening / closing shoji installed in an opening of a building, and more particularly to a locking device that can be unlocked from the outside in an emergency such as a fire. Is.

[Problems to be solved by the prior art and this device]

As disclosed in Japanese Utility Model Laid-Open No. 61-113877, the applicant previously provided an outdoor operation member for opening the lock of the shoji on the outside so that the opening and closing shoji can be opened from the outside in the event of a fire or the like. We have developed a window locking device with a structure that enables the operation.

By the way, in the lock device, since the outdoor operation member is projected on the outdoor surface of the frame constituting the shoji, the outdoor operation member is conspicuously unfavorable in appearance, and at the time of cleaning or inspecting the outdoor surface of the shoji with a gondola or the like. There has been a problem that a gondola or the like may come into contact with a protruding operation member.

As another proposal of this type, as disclosed in Japanese Patent Laid-Open No. 2-300485, since the outdoor operation member is rotated in the direction perpendicular to the longitudinal direction of the frame, there is a problem that the size of the frame becomes large.

An object of the present invention is to provide a locking device for opening / closing shoji which solves the above problems.

[Means for solving the problem]

This invention relates to a locking device for an opening / closing door, and an opening / closing door provided with both indoor and outdoor operating members for operating the locking device mounted inside the door of the opening / closing door from both inside and outside, respectively. The member is pivotally attached to the shaft, rotates in the longitudinal direction of the frame, is mounted so as to be flush with the outdoor side surface of the frame on the outside of the frame, and is adjacent to the outdoor operation member. The above object is achieved by providing a gap between the frame and the frame, and by providing a gap between the frame adjacent to the room operation member and a space for a handle for operating the outdoor operation member.

〔Example〕

1 to 3, a lock device A composed of a stopper is attached to the vertical frame 1 and the vertical frame 2 of an opening / closing door B, and the lock device A is an indoor operation part 3 operated from the indoor side. And the outdoor operation member 4 operated from the outdoor side is provided, respectively. The outdoor operation member 4 is formed by cutting out an outer edge portion of the lower frame 5 on the outdoor side, and the outdoor side surface 4 of the outdoor operation member 4 and the outdoor frame surface of the lower frame 5 are attached to the cutout portion, and An arm 4a protruding inward from the operating member 4 is pivotally attached to a vertical shaft 4b so that the outdoor operating member 4 can rotate in the longitudinal direction of the lower frame 5. Further, a gap W1 is provided between the outdoor operation member 4 and the adjacent frame D, and a gap W2 is provided between the outdoor operation member 4 and the lower frame 5a adjacent to the outdoor operation member 4 so as to serve as a space for operating the outdoor operation member 4. It is possible to insert the hand C into the gap W2 from the gap W to act it.
The lower frame 5 may have a found size H that is relatively small.

Further, the outdoor operating member 4 includes a first interlocking member 7 linked via the arm 4a and the first rod member 6, a second interlocking member 8 and a third interlocking member 9 each made of a flexible leaf spring, and a third interlocking member 9 thereof. And the pin part so that it does not interlock with one direction and the other direction.
A second rod which is arranged so as to be connected to each other by a fourth interlocking member 12 which is connected by 10 and a key portion 11, and which is locked to a stopper 13 which is a locking device attached to the vertical frame 2 on the fourth interlocking member 12. A member 14 is attached.

When the indoor operation member 3 is rotated in the above configuration, the fourth interlocking member 12 slides in the direction of the arrow Y and the second rod member 14 is moved.
Can be released from the stopper 13 to open and close the shoji B. At this time, the key portion 11 provided at the tip of the fourth interlocking member 12 is the pin portion 10.
Since they are further apart, the first to third interlocking members 7, 8 and 9 do not slide, so that the outdoor operation member 4 remains held on the same plane as the lower frame 5, and even if the indoor operation member 3 is operated, the outdoor operation member 4 is operated. The member 4 does not project to the outside of the lower frame 5. Further, when it is desired to open the opening / closing door B from the outside of the room in an emergency such as a fire, if the outdoor operation member 4 is operated to the outside of the room, the first interlocking member 7 slides in the direction of the arrow X, and accordingly, the second to 4 interlocking members 8, 9,
12 also slides. As a result, the second rod member 14 is separated from the stopper 13 so that the opening / closing door B can be opened.

FIG. 4 is an external view of a shoji that implements the structure of the present invention, and FIG. 5 is a perspective view of this essential part.

FIG. 6 shows a first modified example of the present invention, showing that the outdoor operation member can be mounted not only on the lower frame but also on the vertical frame.

FIG. 7 shows a second modified example in which the outdoor operation member is provided over the entire length of the outer edge of the lower frame on the outdoor side in the longitudinal direction.
With this configuration, since the handle portion of the outdoor operation member can be lengthened, the operation member can be lightly operated to open the shoji.

It should be noted that the operating members of the examples shown in FIGS. 1 to 6 are mounted by partially cutting out a frame made of extruded profile, but in the modified example shown in FIG. 7, the extruded profile is notched. The operation member is attached without any operation.

[Effect of device]

Since the present invention is configured as described above, it is possible to operate the outdoor operation member by inserting the hand into the gap between the outdoor operation member and the adjacent lower frame from the gap between the outdoor operation member and the adjacent frame. You can And the opening and closing shoji equipped with the outdoor operation member is mounted on the same surface as the outdoor side of the frame and does not project, so the outdoor operation member is not conspicuous and the appearance is good, and for cleaning and inspection work outside the building Even if the gondola moves near the opening / closing door, it does not come into contact with the outdoor operation member. Further, since the outdoor operation member rotates in the longitudinal direction of the frame, the frame may be found small.
