Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a device for swinging and opening a louver in a louver window in which a plurality of louvers is swingably provided in a window frame.

[Prior Art] Various devices are known as devices for swinging and opening and closing a louver of a louver window.

For example, as shown in Japanese Utility Model Laid-Open No. 57-106987, a louver is provided on a window frame so as to be vertically swingable, each louver is connected to a connecting rod, and the connecting rod is connected to a slider, and a screw rod is used by a handle. There is known an opening / closing device in which the slider is moved up and down to rotate the connecting rod up and down, and thereby the louver is swung to open and close.

[Problems to be solved by the device]

In such an opening / closing device, a mechanism for converting the rotation of the screw rod into vertical movement of the slider is required, and the screw rod is rotatably supported on the window frame, and the slider is required to be vertically movable on the window frame. However, the number of parts is increased and the structure is complicated, resulting in high cost and an extremely complicated assembly work.

Therefore, an object of the present invention is to provide an opening / closing device for a louver window that can solve the above-mentioned problems.

[Means and Actions for Solving the Problems]

Connect the movable arm to the outer surface of the connecting rod that swings the louver,
This is a louver window opening / closing device that connects an arm to the outer surface of the movable arm and engages a worm wheel equipped with this arm at a position eccentric to the outside of the worm center to use as a drive mechanism, thereby rotating the worm. By doing so, the arm is swung, and by moving the connecting rod via the movable arm, the louver is swung and the louver window can be opened and closed.

〔Example〕

As shown in FIG. 3, the louver window is provided with a plurality of louvers 2 swingably provided on the window frame 1, and is opened and closed by swinging the louvers 2 between a substantially vertical posture and a substantially horizontal posture. .

As shown in FIGS. 1 and 2, the louver 2 has a panel 4 extending horizontally between the inner surfaces of a pair of left and right holders 3, 3, and the holder 3 is attached to a vertical frame 5 of the window frame 1. It is supported so that it can swing up and down.
A connecting rod 7 is pivotally connected to the outer surface of the bending arm 3a of each holder 3 via a spacer 6, and a movable arm 8 is provided on the lower outer surface in the longitudinal direction of the connecting rod 7 so as to be vertically rotatable. is there.

The drive mechanism 10 is attached to the indoor side horizontal plate 9 of the vertical frame 5,
As shown in FIGS. 4 and 5, the drive mechanism 10 includes a main body 11 provided with an electric motor 12, a worm 13, and a worm wheel 14,
The drive side 12a of 12 is connected to the worm 13, the worm wheel 14 is meshed with the worm 13, and the arm 15 is integrally provided on the worm wheel 14 so that the worm 13 rotates in the forward direction, and when the worm wheel 14 rotates in the reverse direction, the worm wheel 14 rotates in the forward direction. In reverse, the arm 15 swings up and down with the rotation support shaft 16 of the worm wheel 14 as a fulcrum.
It is meshed with a position eccentric to the outside of the center 13a.

A manual operation unit 17 is integrally provided on the lower portion of the worm 13, and a cover body 18 is detachably attached to the main body 11.

The arm 15 is, as shown in FIG. 1, a horizontal plate 9 on the indoor side of the vertical frame 5.
It projects from the opening window 19 formed in the above to the louver 2 side and is connected to the outer surface of the movable arm 8 so as to be vertically rotatable.

Then, when the electric motor 12 is rotated in the normal direction and the reverse direction, the worm 13 and the worm wheel 14 are rotated in the normal direction and the reverse direction, and the arm 15 swings up and down. Since the panel 4 swings up and down and swings up and down, and the louver 2 swings in a substantially horizontal posture and a substantially vertical posture, the louver window can be opened and closed.

Further, since the meshing position of the worm 13 and the worm wheel 14 is eccentric to the outside of the worm center 13a, when the worm 13 is rotated, the component force F ₁ acting on the worm wheel 14 diagonally outward acts, This component force F ₁ pushes the worm wheel 14 outward with the rotation support shaft 16 as a fulcrum, so that a reaction force F ₂ acting diagonally inward acts on the connecting portion with the movable arm 8, and the movable arm 8, Since the connecting rod 7 is pressed against the outer surface of the bending arm 3a of the holder 3 via the spacer 6 by the reaction force F ₂ , rattling between them does not occur and the louver 2 can be swung smoothly.

Although the louver 2 is vertically swingable in the above-described embodiments, the louver 2 may be horizontally swingable over the upper and lower frames of the window frame 1.

In this case, the drive mechanism is attached to the inner surface of the upper frame or the lower frame.

[Effect of device]

A drive mechanism 10 including a worm wheel 14 having an arm 15 and a worm 13 is attached to the indoor side surface of the window frame 1, and the arm 15 is connected to a movable arm 8 provided on a connecting rod 7 connected to the louver 2. The worm wheel 14 is rotated by rotating 13 to swing the arm 15, the connecting rod 7 is moved via the movable arm 8 to swing the louver 2 to open and close the louver window, and the number of parts is reduced. Not only can the structure be reduced, the cost can be reduced, and the assembly can be done easily at a low cost. In addition, the movable arm 8 can be connected to the louver side and the drive mechanism 10 can be attached to the window frame 1 side. Can be installed.

Further, the worm wheel 14 meshes with a position displaced outward from the worm center 13a, the arm 15 is on the outer surface of the movable arm 8, the movable arm 8 is on the outer surface of the connecting rod 7, and the connecting rod 7 is on the outer surface of the louver 2. Since they are connected to each other, when the worm 13 is rotated, an outward component force acts on the worm wheel 14, and the arm 15 is pressed against the outer surface of the movable arm 8 by the reaction force of the component force. 8, the connecting rod 7, the louver 2 connecting portion does not rattle,
The louver 2 can be swung smoothly.
