Description

[Detailed explanation of the idea] The present invention relates to window locks for vehicles, etc.

The opening/closing operation of a conventional window with a structure that opens and closes in the vertical direction consists of two operations: removing the lock and lowering the rear window, which makes the operation cumbersome.

The object of the present invention is to provide a window lock which has an extremely simple structure consisting of a leaf spring and a release mechanism, and which can open the window with a single push button operation.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 1 shows an overall view of the installation of the present invention, in which 1 is an upper window that opens and closes in the vertical direction with respect to a fixed position 2.

1a is the handle of the upper window 1, and 3 is the window lock of the present invention, the details of which are shown in FIGS. 2 and 3.

Reference numeral 4 denotes a leaf spring whose one end is fixed to both corners of the upper window 1 with mounting screws 5, and the tip of the leaf spring 4 is engaged with the upper end of the lower part 2 to support the upper window 1.

6 is a push button for pushing the leaf spring 4; 7 is a bearing for the push button 6; 8 is a snap ring;
The bearing 7 and the snap ring 8 constitute a leaf spring release mechanism 9.

10. 10' is a mounting screw that connects the bearing 7 to the upper stile 2 of the window 2.
' and fixed to the window frame 11.

Next, to explain the operation, when closing the upper window 1, when the upper window is pulled upward by the handhold 1a, the leaf spring 4 comes into contact with the tip of the push button 5, and at the same time locks with the upper end of the lower button 2. The upper window is fixed in a predetermined position (as shown by solid lines in FIGS. 2 and 3).

Next, when opening the upper window 1, press the push button 6 lightly. The leaf spring 4 is pushed by the tip of the push button 6, disengaging from the lower part 2, and the upper window is in the position shown by the chain line. 1 falls under its own weight and opens.

FIG. 4 shows another embodiment, in which 12 is a lever-type push button, 12a is a claw portion thereof, and 12b is a push button portion.

13 is a bearing of the push button 12, 14 is a return spring,
The push button 12, the bearing 13, and the return spring 14 constitute a mechanism for removing the leaf spring 4.

The operation is the same as in the previous embodiment, and when opening the upper window 1, press the push button part 12b of the lever push button 12, and the claw part 1 will open.
2a pushes the leaf spring 4, the lower part 2 is released from the lock, and the upper window 1 falls to the position shown by the chain line in the figure.

In both of the above embodiments, the release mechanism 9 is provided at the lower part of the fixed upper part of the window that opens and closes in the vertical direction, but the release mechanism 9 can be provided not only at the window sill but also at any place where the window is fixed, such as the window frame. good.

Although I have explained the window with two panes on the top and bottom, it can of course also be used for windows with one pane or three or more panes.

Since the present invention has the above structure, it has the following effects compared to the conventional one.

(1) The window can be opened easily with a single touch of a push button.

(2) The window can be locked by simply raising it.

(3) It has fewer components and can be provided at a lower price.

In this embodiment, window locks are provided on both sides of the window, but depending on the inside of the window, the locks may be located in the center.In this case, the lock can be operated with one hand and is easier to operate.

[Brief explanation of the drawing]
