JPS5912361Y2 - Handle mechanism for door and window pulling or locking devices - Google Patents

Description

[Detailed description of the invention] This invention is a door that pulls together the door and window in conjunction with the rotating operation of the handle, strongly closing the gap between the door frame and the window frame to improve watertightness and airtightness. This invention relates to a handle mechanism in a window pulling or locking device.

The locking and unlocking operations of the above-mentioned door and window pulling or locking devices are generally performed by rotating a handle. Although the mounting device is selected according to the size and shape of the handle, the rotation angle of the handle may be arbitrary in order to conveniently perform the above-mentioned operations at each mounting position, or from the viewpoint of installation or appearance. It is desirable to be able to select the desired angle, but since all handle mechanisms in conventional devices of this type have a constant rotation angle, the above-mentioned wish cannot be satisfied.

Therefore, the KAI device has created a new handle mechanism with an extremely simple structure that allows the rotation angle of the handle to be arbitrarily selected according to the installation conditions of the door, window drawer, or locking device.

The drawings showing the embodiments of the present invention will be described in detail below.
In Figures 1 and 2, screws 3 are attached to the hollow frame 2 of the door and window 1.
A handle shaft 5 is supported on the seat plate 4 which is fixed by a stopper, and projects outward from the inside of the hollow vertical frame 2, and the inner end of the handle shaft 5 has a shaft that rotates integrally with the shaft 5. A manual piece 7 is fixed by a retaining ring 6 which can be screwed on, and a nozzle 9 is integrally and rotatably attached to the outer end of the manual piece 7.

Two driven pieces 11 and 12 are installed vertically symmetrically in a case 10 fixed together with the seat plate 4 by the screws 3 in the hollow vertical frame 2, and are vertically movable and connected to the main driving piece 7 by a pin. ing.

Both driven pieces 11 and 12 are engaged with receiving portions of the door frame and window frame (not shown) in order to draw and close the door and window 1 in a watertight and airtight manner, and to lock the door and window 1. An upper rod 13 and a lower rod 14 are connected to each other, which are arranged so as to be vertically movable inside the hollow vertical frame 2.

In the door/window pulling or locking device A having such a configuration,
The handle mechanism B of the present invention is shown in Fig. 2, Fig. 4 A, B, and Fig. 5.
In Figures A and H, the disc-shaped drive piece 7 has two
Pin drive grooves 16.17 are provided in a substantially circular arc shape on the front side and at desired lengths at appropriate angles θ, θ', and each pin drive groove 16.17 has a protrusion from the driven piece 11.12. The provided pins 18 and 19 are engaged with each other.

More specifically, the pin driving grooves 16 and 17 are provided equidistantly from the center O of the main moving piece 7 and long in the circumferential direction,
Bend grooves 16 bent toward the center at both ends in the length direction
', 16'', 17', 17'' are arranged in series, and the effective movement strokes of the pins 18 and 19, that is, the angles θ and θ' are respectively 60° as shown in FIGS. 4A and B. , or at an angle of 80° as shown in FIGS. 5A and 5B.

In other words, the angles θ and θ' determine the rotation angle α of the handle 9 from the release position to the closing or locking of the door or window 1, so if the angles θ and θ' are set as shown in FIG. 4A,
When the angle is 60 degrees as shown in B, the rotation angle β of the pins 18 and 19 from the release position to the closing or locking of the door or window is 90 degrees.
degree, the rotation angle α of the handle 9 is set to 150 degrees.

In addition, in FIGS. 5A and 5B, the rotation angle α of the handle 9 is 1.
It is set at 80°.

Therefore, by setting the angles θ and θ' to appropriate angles in advance, the rotation angle α of the handle 9 can be arbitrarily selected.

As explained above, according to the handle mechanism according to the present invention, the driven piece 11.
By arbitrarily setting the effective pin movement angles θ and θ' of the pin drive grooves 16 and 17 of the main moving piece 7 that engage the 12 pins 18 and 19, the rotation angle α of the handle 9 can be set to a desired angle. Therefore, by setting the angles θ and θ' to appropriate angles in advance and using the main moving piece 7 provided with the pin drive grooves 16 and 17, it is possible to eliminate the possibility that the size and shape of the door or window or the mounting method are different. The rotation angle of the handle 9 can be adjusted arbitrarily depending on the installation position and orientation of the door, door to window, window pulling or locking device, and the appearance. The pulling, locking, and releasing operations can be performed conveniently, and the conventional door/window pulling/locking device can be simply interposed with the main actuating piece 7 without any particular improvement, and the structure or the simple structure can be achieved. Therefore, it has practical effects such as being able to be manufactured at low cost.
