Description

[Detailed Description of the Invention] The present invention is a so-called door lock handle device that is operated by hand when opening and closing the door, and in particular, the door lock is unlocked by pushing the handle. This invention relates to a handle device.

Conventional handle devices can be broadly divided into those that unlock when the handle is rotated to the left or right, and those that unlock by pushing or pulling the handle. There is a structure designed to do this.

In particular, in devices that are designed to be unlocked when the handle is pushed out or pulled, when the handle is operated by hand, the lock will be unlocked if the hand position relative to the handle is not in the specified position. The disadvantage is that it cannot be performed.

The purpose of the present invention is to eliminate this drawback, and to enable the lock to be unlocked no matter where the hand is placed on the handle.

This object is fully and satisfactorily solved by the following means.

The present invention has a handle cover that moves up and down so that the lock can be unlocked by pushing or pulling the handle at any position. One end of a rotary lever that drives a locking device (not shown) is pivotally supported on the other end of this vertically movable frame, and the middle of this rotary lever is attached to a fixed frame. This is a handle device for a door lock which is pivotally supported by the handle device, and the gist thereof is as set forth in the claims.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a front view of a door lock handle device that is provided on the indoor side of the door and unlocks when pushed;
FIG. 2 is a longitudinal sectional side view of FIG. 1, and FIG. 3 is a side view of the main parts.

1 is a housing body that is fixed to a door (not shown). The eldest child 2 of this housing body 1 can freely rotate up and down MK.
is provided.

A handle cover 3 is still movably provided on the front surface, and the upper and lower ends of the vertically movable frame 4 are fixed to this handle cover 3 with screws 5. A fixed frame 6 is provided outside the vertically movable frame 4, and the fixed frame 6 is fixed to the housing body 1 with screws 5.

In FIG. 3, one end 4a of the vertically movable frame 4 and one end 6a of the fixed frame 6 are fixed to the handle cover 3 (not shown).
The spring 9 is fitted into the pin 7a so that both ends of the support frame 7 are pivotally supported by the pins 7a and 7b, and the support frame 7 is always urged outward by the spring 9. One end 9a of 9 contacts the wall surface 8 of the fixed frame 6,
The other end 9b is brought into contact with the wall surface 7C of the support frame 7.

Still, one end 10a of a bent rotary lever 10 that drives a locking device (not shown) is supported by a pin 11 on the other end 4b of the vertically movable frame 4, and the other end 10a of the rotary lever 10 is also The middle part is rotatably supported by a bottle 12.

In this way, the present invention provides a handle cover 3 with a vertically movable frame 4.
At the same time, support shafts 7a, 7b, and 11.12 are provided on the support frame 7 and the rotating lever 10 at the top and bottom of the vertically movable frame 4, so even if you push the upper part by hand from the B side, it will still not work. Even if the middle or lower part is pushed from side B, the rotating lever 10 will rotate in the direction of arrow A around the bottle 11, so when the drive plate (not shown) of the locking device is pushed up, Can be used for devices such as unlocking. If you release your hand from the handle cover 3, the spring 9 will automatically return it to its original position. Although the description in the present invention is for the handle device on the indoor side, the handle device on the outdoor side only requires replacing the heir 20 portion with a cylinder lock (not shown).

FIG. 4 shows another embodiment in which the rotating lever 0 rotates when pulled by hand, and in particular, the rotating lever 1
By changing the direction of the handle 0, placing your hand on the A side, hooking your finger on the B side, and pulling the handle in the direction of the A side, the operation will not be activated in part in the same way as the push operation described above. At the same time, the rotary lever 10 can also be rotated in the direction of the arrow, so it can be used in a device that unlocks when a drive plate (not shown) of a lock device is pressed down.

As described above, the present invention has the practical effect that the rotating lever 10 rotates no matter where the handle cover 3 is pressed, so that the locking device can be smoothly driven and unlocked. It is something to play.
