Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an opening angle adjusting device for a casement window.

[Conventional technology]

BACKGROUND ART Conventionally, casement windows have been provided with an opening angle adjustment device to maintain the opening degree at a desired level. For example, this type of device disclosed in Japanese Utility Model Application Publication No. 48-28644 has a case and other stopper means provided on the upper surface of the lower window frame, and the case and the shoji are connected by an arm. .
During operation, the shoji is opened with one hand while the other hand is used to press the stopper means attached to the window sill, releasing the stoppers one after another and releasing the stopper means to engage at the desired opening angle. It is. In addition, in Japanese Utility Model Application Publication No. 58-90955, a fixing plate in which a long hole with locking holes at various places is formed is attached to the bottom of the shoji, and a locking pin is provided by inserting into the long hole. In contrast to the conventional window opening angle adjustment device in which this locking pin and one end of the window sill are pivotally connected by a lever,
Furthermore, a sliding plate capable of reciprocating in the direction of the fixed plate is provided between the fixed plate and the lever, and a protruding portion is formed on the fixed plate and a protruding portion is formed on the sliding plate. , Due to the reciprocating movement of the sliding plate, the protruding part of the sliding plate rides on the convex strip of the fixed plate, thereby moving the sliding plate up and down, and this operation pushes the locking pin in the vertical direction. There is a disclosure of a device in which the locking pin can be manually disengaged by moving the locking pin.

[Problem that the invention attempts to solve]

However, in the device disclosed in the above-mentioned Japanese Utility Model Application Publication No. 48-28644, both hands must be used for operation as described above, and the operation requires a great deal of effort, such as having to keep pushing the stopper means until the desired opening degree is reached. . Also, when closing, especially when you insert your hand to release the stopper attached to the window sill just before closing, if the shoji suddenly closes due to strong winds, your hand may get caught. There is a risk. On the other hand, since the case and stopper means are attached to the window sill, they are within the field of view of the operator and occupants, resulting in a poor appearance. In addition, the aforementioned Jikaiaki
The device in Publication No. 58-90955 has a three-stage structure on the bottom side of the shoji, including a fixed plate, a sliding plate, and a lever, so when installing it, it is necessary to attach each component to the shoji and assemble it. This requires a considerable amount of effort and also has a bad appearance.

Therefore, the main purpose of the present invention is to provide a casement window opening angle adjustment device that is easy to attach to a shoji screen, has excellent operability, eliminates danger during operation, and has an excellent appearance. .

[Means for solving problems]

In order to solve the above problems, the present invention provides a casement window in which the vertical stile of the shoji is supported by the window frame, and the lower stile of the shoji and the lower frame of the window are connected by an arm. A hollow case is attached along the stile, and an actuating plate is provided along the inner surface of the top plate of the hollow case, which is movably operated along the longitudinal direction of the shoji by means of a shutter attached to the interior surface of the shoji. In addition, a convex portion is formed on the top plate of the hollow case toward the inside, and a convex portion opposing the convex portion is formed on the movable plate, so that the convex portion of the movable plate and the convex portion of the movable plate are formed by moving the actuating plate. The actuating plate is configured to move up and down when the convex portions on the top plate side are offset or run over, and a guide elongated hole is formed in the bottom plate of the hollow case along its longitudinal direction, and a stopper is inserted through the guide elongated hole. is arranged, one end of which is disposed opposite to the lower surface of the actuating plate, and the other end pivotally connected to the arm, and as the actuating plate moves up and down, the stopper can be freely engaged and disengaged at a predetermined portion of the guide elongated hole,
Furthermore, the stopper is configured to be relatively movable along the guide slot as the shoji opens.

[Effect]

In this invention, a hollow case and a stopper are attached to the lower surface of the lower stile of a shoji screen, and an operating plate for operating the stopper is housed inside the hollow case.
What's more, the camera that moves the operating plate is attached to the interior surface of the shoji screen. Therefore, the stopper and actuating plate are housed in a hollow case, and the hollow case is attached to the underside of the lower stile, so even with the shoji open, the device is out of sight in a normal standing position. The main body of the camera cannot be seen, only the camera is visible, giving it an excellent appearance. In addition, when the camera is placed on the indoor surface of the shoji, the stopper is engaged/disengaged and moved relative to each other by its operation, so it can be pushed open with the same hand holding the camera, and the operation can be performed. It is very easy to do so, and since you do not have to insert your hand into the window sill like in the past, there is no risk of your hand getting caught between the shoji and the window sill due to the wind. In addition, in this invention, a hollow case is used, and the device part to be attached to the shoji side is housed in this hollow case. Therefore, when installing, the actuating plate, stopper, etc. must be assembled in the hollow case in advance. Since this hollow case can be attached as one unit of one assembly block, the labor required can be significantly reduced.

〔Example〕

The present invention will be explained in more detail below with reference to embodiments shown in the drawings.

Reference numeral 1 denotes a shoji shoji, which is rotatably held in window frames 3A to 3D around a rotating shaft 2 provided in the vertical stile. The shoji 1 and the window lower frame 3B are connected by an arm 4.

The lower surface of the lower stile 1A of the shoji 1 has a seat plate 11 and an outward flange 12a along its longitudinal direction.
A hollow case 10 consisting of a letter-shaped main body 12 is fixed with a set screw 51. hollow case 10
A guide slot 14 is formed in the bottom plate 13 along its longitudinal direction. This guide slot 14 includes a sliding parallel part 14a and a plurality of positioning circular holes 14.
It has b.

On the other hand, an actuation plate 20 is disposed inside the hollow case 10. This actuating plate 20 has two elongated holes 2.
1 and 21 are formed, and guide pins 52 and 52 are disposed passing through these elongated holes 21 and 21, and the upper ends of the guide pins are fixed to the seat plate 11. Further, a repulsion spring 52a is interposed between the flange portion of the guide pin 52 and the lower surface of the actuating plate 20, and thereby the actuating plate 20 is urged toward the seat plate 11 side. Further, the actuating plate 20 has an engaging portion 22 at its end that rises orthogonally toward the hollow interior of the lower stile 1A, and penetrates through the through hole 11c of the actuating plate.

On the other hand, on the indoor surface of the lower stile 1A of the shoji 1, for example, an operation camera 30 is provided which is movable in the horizontal direction along a mounting base 53, and its foot portion 31 extending toward the hollow interior of the lower stile 1A is They are in an engaged state with the engaging portion 22 interposed therebetween. Now, if this operation camera 30 is moved horizontally while standing indoors, the actuating plate 20 will also be moved horizontally, in other words, horizontally within the hollow case 10 along its longitudinal direction. At this time, the actuating plate 20 moves linearly while being guided by the engagement between the elongated hole 21 and the guide pin 52.

Further, two through holes 11a are formed in the seat plate 11, and the right side of the through holes 11a in FIG. 1A is a guide portion 11b that curves upward like the tip of a ski. On the other hand, the actuating plate 20
Two raised portions 23, 23 are formed at positions corresponding to the through holes 11a, 11a, and these protrusions 23, 23 are inserted into the through holes 11a, 11a during normal operation. However, now by operating the operation camera 30, the actuating plate 20 is
Spring 5 is moved horizontally to the right from the state shown in Figure 1A.

It gradually crawls under and finally moves to the bottom surface of the actuating plate 20. This causes the actuating plate 20 to move substantially downward in translation. If the actuating plate 20 is moved in the opposite direction, it will return to its original state, but at this time the spring 52a will press the actuating plate 20 against the seat plate 11.

A stopper 40 penetrates through the guide slot 14 and engages with it. The upper end of the stopper 40 is the actuating plate 20
The lower end is pivotally connected to the connecting arm 4. The other end of this connecting arm 4 is the window lower frame 3B.
It is pivotally connected by a fixing plate 54 and a pin 55 fixed to. Furthermore, the stopper 40

It has a small diameter portion 42 with a diameter corresponding to the width of.
Additionally, a flange portion 43 at the upper end and a spring seat 44 loosely fitted into the stopper 40 and installed on the upper surface of the bottom plate 13
A repulsion spring 45 is interposed between the two. As a result, the stopper 40 is urged upward so that its upper end comes into contact with the lower surface of the actuating plate 20.

The left end of the washer 11 and the left end of the actuating plate 20 are connected by a spring 56, so that when the actuating plate 20 is returned to the left after opening the shoji 1, the raised portion 23 is correctly aligned with the through hole 11a. It is designed to fit inside.

In fittings having a device configured in this way, when opening the shoji 1, the operation camera 30 is
Move horizontally to the right in Figure A, and move the actuating plate 20 to the right. As a result, the actuating plate 20 moves downward, and as a result, the stopper 40 is also pushed downward, and the small diameter portion 42 is positioned in place of the large diameter portion 41 that has been engaged with the circular hole portion 14b. . In this state, use the hand that is holding the operation camera 30 or use your other hand to move the shoji outside the room.
Push out. As a result, since the large diameter portion 41 has already come off from the circular hole portion 14b, and the stopper 40 is connected to the connecting arm 4,
As the shoji 1 is opened, the stopper 40 moves from the circular hole part 14b to the parallel part 14a while being pushed downward, and moves along the guide slot 14 to the first B.
Move to the right in the diagram. Then, when the stopper 40 is positioned at a desired position in each circular hole 14b, if the operation camera 30 is moved in the opposite direction, the actuating plate 20 will rise, and at the same time the stopper 40 will also rise, allowing the selection. The large diameter portion 41 fits into the circular hole portion 14b,
remains engaged. As a result, the opening of the shoji 1 is maintained at the desired opening.

At the time of closing, the closing is performed by basically operating the same members as described above.
