Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a revolving window opening/closing device.

(Prior Art) Various technical means have been proposed as opening/closing devices for rotating windows, but their structures are extremely complicated. As this type of switchgear, for example,
A window opening/closing device disclosed in Japanese Patent No. 118265 is known.

(Problems to be solved by the invention) Although the opening/closing device described in the above publication is said to have a relatively simple structure, in order to provide a locking function, the handle rod is fitted into the handle insertion rod. In addition, the tip of the handle rod is formed into a prismatic shape, so that a rotation transmission path to the pinion is provided separately, making the device as a whole complicated.

Therefore, the conventional revolving window opening/closing device requires a wide variety of parts for manufacturing, increases the number of assembly steps, and complicates the maintenance and management of the parts.

(Means for solving the problems) The present invention employs the following technical means to solve the above problems.

That is, a horizontally rotatable pinion is attached to the lower frame of the shoji, and the shaft of the pinion is protruded from the upper part, and two upper and lower pinions are pivoted so that the base end of each can rotate in the vertical direction. Of the arms,
The upper arm is engaged with the shaft of the pinion, and the lower arm is engaged with the window frame, and on the other hand, a sliding piece that engages with the pinion and moves in the horizontal direction is attached to the lower frame of the shoji. A tapered lock piece is attached to each frame, and the base ends of the upper and lower arms are rotated vertically as a unit to open the shoji, and the upper and lower arms are rotated horizontally as a unit. As a result, the pin body restrained by the sliding piece moves together with the sliding piece to approach and separate from the locking piece.

(Function) According to the above configuration, by horizontally rotating the upper and lower arms, the pinion meshing with the rack can rotate on a horizontal plane and move the rack, simplifying the rotating window opening/closing device. Specifically, by attaching the pinion to the shoji screen, it is possible to open, close, and lock the window without requiring any separate members.

(Example) Hereinafter, the present invention will be described in detail with reference to illustrative drawings.

FIG. 1 is a partially cutaway front view of an embodiment of the present invention, FIG. 2 is a plan view thereof, and FIG. 3 is a sectional view showing the relationship between a pinion and a sliding piece.

In the figure, 1 is a shoji, 2 is a window frame, and between the shoji 1 and the window frame 2, an opening/closing device 3 according to the present invention is provided.
is attached. That is, the box body 4 is attached to the lower part of the shoji 1 with screws 5 so as to protrude into the room, and the pinion 6 is housed inside the protrusion of the box pair 4 so as to be horizontally rotatable, and the rotation axis of the pinion 6 ( A shaft 7 (hereinafter abbreviated as "shaft 7") is provided to protrude upward, and the protruding portion is integrated with a cylinder body 9 provided with a flange 8, and an upper arm 10 is pivotally attached to the flange 8 so as to be rotatable in the vertical direction. are doing.

Further, a base plate 11 protruding toward the indoor side is fixed to the window frame 2, and an intermediate base 12 is mounted on the base plate 11 so as to be rotatable in the horizontal direction with a pin 13.
A lower arm 15 is vertically rotatably pivotally attached to a flange 14 protruding from the upper part of the upper arm 2, and the base ends of the upper arm 10 and lower arm 15 are vertically rotatable and pivoted by a pin 16. A handle 17 is attached to the protrusion of the pin 16.

A guide groove 18 is formed in the box body 4 at a position close to the shoji 1, and a sliding piece 19 that can move along the guide groove 18 is installed inside, and an end of the sliding piece 19 close to the pinion 6 is provided. A rack 20 that meshes with the pinion 6 is formed on the edge, and the edge of the sliding piece 19 closer to the shoji 1 has a shape U in plan view as shown in FIG.
A character-shaped restraining hole 21 is provided in a recessed manner, and the pin body 22 engaged with the restraining hole 21 moves together with the sliding piece 19. 23 is a lock piece with a taper 24 fixed at a suitable position on the upper edge of the window frame 2;
The lock piece 23 plays the role of forming the shoji 1 on the window frame 2 by allowing the pin body 22 to ride on it.

That is, while the pin body 22 is not in contact with the lock piece 23, the upper arm 10 and the lower arm 15 are rotated in the direction shown by arrow A in FIG. 1, and the shoji 1 is moved in the direction shown by arrow B in the same figure. The shoji 1 is opened by performing the operation opposite to the above operation, and the shoji 1 is closed. After closing the shoji 1, move the upper arm 1 in the direction shown as arrow C in FIG.
0 and the lower arm 15 to rotate the pinion 6, and the sliding piece 1 is meshed with the pinion 6.
9 is moved to cause the pin body 22 to ride on the lock piece 23, thereby making the lock state.

(Effects of the invention) As described above, this invention allows windows to be opened, closed and locked, and its configuration is significantly simplified by installing a horizontally rotatable pinion protruding from the shoji. This provides the public benefit of reducing man-hours and reducing the number of parts, making maintenance management easier.
