Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is characterized in that an arm formed integrally with the worm foil rotates by the rotation of a worm that meshes with a worm foil pivotally supported within the case body. ,
The present invention relates to a louver window opening/closing device configured to be opened and closed by rotation of the arm.

<Conventional technology> Conventionally, the third type of opening/closing device for louver windows has been used.
The ones shown in Figures 5 to 5 are used.

In this opening/closing device, an arm 2a formed integrally with the worm wheel 2 rotates by the rotation of a worm 3 that meshes with a worm wheel 2 pivotally supported in a case body 1, and each arm 2a is rotated by the rotation of the arm 2a. It is configured to open and close the louver window.

That is, the opening/closing device rotatably supports a worm wheel 2 in a case body 1 attached to a window frame or the like, and a worm 3 that engages with the worm wheel 2 is tilted and integrated with the side 1a of the case body 1. The worm 3 is rotatably accommodated in a cylindrical body 4 protruding from the worm 3.
A handle 5 having a handle 5a is fitted to one end shaft portion 3a, and an arm 2a formed integrally with the worm wheel 2 is pivotally connected to a connecting rod 7 to which each louver window 6 is attached via a lever 8. The worm wheel 2 that engages with the worm 3 rotates when the handle 5 is rotated.
An arm 2a formed integrally with the worm wheel 2 rotates as the worm wheel 2 rotates, and a connecting rod 7, which is connected to the arm 2a through a lever 8, is moved in the vertical direction. The supported louver windows 6 are opened and closed all at once.

<Problems to be solved by the invention> The above-mentioned louver windows are intended for indoor ventilation and lighting, and with the recent changes in living room configurations, they are also being used for reasons of interior aesthetics.

However, these window opening/closing devices are usually installed at a height of about 1 m from the floor in consideration of ease of operation when opening and closing, but they have the disadvantage that the handle in particular protrudes significantly toward the indoor side.

This drawback can become an obstacle when passing by a window equipped with an opening/closing device, and in the case of young children, it can hit the head of the vehicle, leading to unexpected accidents.

The present invention has been made to solve the above-mentioned drawbacks, and provides a window opening/closing device in which the handle tilts when not in use, and the protrusion toward the interior of the room is extremely small.

<Means for solving the problem> The present invention adopts the following technical means, that is, the configuration, in order to achieve the above-mentioned object.

A handle 18 is pivotally supported in the elongated hole 19, and has a bent portion 18b at the other end, extends diagonally, and has a handle 18c at the end. The handle 18 is connected so that it can move in a direction perpendicular to the shaft 17 and rotatably around the shaft 17.
The upright state is maintained by fitting into a,
This louver window opening/closing device is characterized in that it is configured to be tiltable when the fitting is released.

<Operation> When opening/closing a window, by rotating the handle pivoted on the shaft around the shaft and pushing it, the handle moves along the elongated hole, and the cylindrical convex surface at the tip of the handle is attached to the handle holder. It is held in the upright position by fitting into the cylindrical concave surface at the bottom of the concave groove. In this state, the window is opened and closed by rotating the handle.

Also, when not in use, by pulling the handle,
As the handle moves along the elongated hole, the cylindrical convex surface at the tip of the handle and the cylindrical concave surface at the bottom of the groove are disengaged from each other. By rotating the handle around the axis in this state, the handle is held in the tilted position.

<Example> The contents will be explained in detail below using FIG. 1 and FIG. 2 corresponding to the example.

In addition, in the embodiment, the same parts as those of the prior art described above will be described with the same reference numerals.

A worm 3 is rotatably housed in a cylindrical body 4 integrally protruding from the side 1a of the case body 1.
One end shaft portion 3a protrudes outside the cylinder 4, and the worm 3 has a
A worm wheel 2 integrally equipped with an arm 2a is engaged with a connecting rod 7 to which each louver window 6 is pivotally connected via a lever 8, and the worm foil 2 is pivotally supported within the case body 1. has been done.

A shaft portion 3a of the worm 3 protruding from the cylindrical body 4
A handle holder 9 is connected and fixed to the handle holder 9.

The handle holder 9 has a cylindrical portion 9a having the same diameter as the outer diameter of the cylindrical body 4, and a rectangular parallelepiped portion 9b integrally formed continuous with the outer periphery of the cylindrical portion 9a. The connection and fixation between the portion 3a and the handle holder 9 is achieved by fitting the shaft portion 3a into a hole 10 formed in the cylindrical portion 9a of the handle holder 9 and screwing into a screw hole 11 communicating with the hole 10. This is done by screws 12.

The rectangular parallelepiped portion 9b of the handle holder 9 has an opening extending across the lower surface and end surface of the rectangular parallelepiped portion 9b at the end opposite to the cylindrical body 4, and a cylindrical concave surface portion 13a at the bottom.
A groove 13 having a rectangular cross section is formed.

A shaft 17 having both ends fixed to the side walls of the groove 13 is disposed in the groove 13 .

The shaft 17 has a cylindrical convex portion 18a at one end and an elongated hole 19 near the cylindrical convex portion 18a, and the other end has a bent portion 18b and extends obliquely, and has a handle 18 at the end.
A handle 18 having a diameter c is pivotally supported in the elongated hole 19, and the handle 18 is coupled to be movable along the elongated hole 19 in a direction orthogonal to the axis 17.
