Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handle device for a door of a storage cabinet provided facing a room or a hallway.

Conventional doors have the following drawbacks because they have a handle projecting from the front for opening the door and a locking device for securing the door.

First, since the handle is provided in a protruding manner on the front of the door,
The handle becomes a nuisance, and there is a drawback that it is dangerous to walk when the handle protrudes, especially in a storage cabinet provided in a hallway, and the protruding handle also has the disadvantage of being unsightly.

Second, conventional door locking devices were of the type in which the door was removed from the fixed frame or fixed to the fixed frame by applying force to open or close the door. The drawback was that the door would open automatically if some force was applied to it, even if it was not intended to be opened.

This invention eliminates the above-mentioned drawbacks by providing a handle that can move forward and backward with respect to the door so that it can be stored inside the door when not in use, and by operating a locking member in conjunction with the handle. The purpose is to

The present invention will be explained below based on embodiments shown in the drawings.

As clearly shown in FIG. 1, the free end of the door 2 is provided with a through hole 26 extending from its front surface to its rear surface.

A decorative ring 25 is fitted onto the front peripheral edge of the through hole 26, and a handle 3 is fitted into the through hole 26 so as to be movable forward and backward.

An annular finger rest 9 is formed in the peripheral wall of the bottomed cylindrical body 6 of the handle 3 to make it easier to put a finger on the handle 3.

A shaft body 7 is provided on the main body 6 in a rearwardly projecting manner, and this shaft body 7
A bottle 8, which is a part of the handle fixture 5, is provided on the lower surface of the tip of the handle fixture 5 in a downwardly protruding manner.

The shaft body 7 is slidably fitted into a guide rail 10 in a casing 27 (see FIG. 2) attached to the rear surface of the door 2.
The pin 8 protrudes downward through a slit 11 formed on the lower surface of the guide rail 10.

An elastic spring 1, which is a part of the handle fixture 5, is fitted into the shaft body 7. The front end of this spring 1 is applied to the main body 6, and the rear end is applied to the front end of the guide rail 10. Due to this action, the pusher 3 is always urged in the direction of protruding forward.

The pin 8 is a swinging member 1 that is a part of the handle fixture 5.
It is movably fitted into an endless groove 14 formed in 2.

A support shaft 1 fitted into a shaft hole 13 at the front end of the swinging member 12
The guide rail 10 is pivotally connected to the front end of the guide rail 10 via the guide rail 5.

With such a structure, the swinging member 12 is able to swing horizontally, that is, in a direction that crosses the center line in the advancing and retreating direction of the pusher 3.

Further, the swinging member 12 is biased in the direction shown by the arrow A in FIG. It is designed so that it will not come off.

The en-dress groove 14 includes a long notch-shaped pin locking portion 14'' on the front end, and a pin locking portion 14' on the rear end.
It has a round trip path connecting these.

With this configuration, the handle 3 can be changed from the protruding or retracted state before being pressed to the opposite state every time a suppression operation is applied to the handle 3.

The operation will be explained in detail with reference to FIGS. 2a and 2b as follows.

When the handle 3 is in a state of protruding from the front surface of the door 2 due to the action of the resilient spring 1, the pin 8 is in a state of being locked in the pin locking portion 14''.

The pusher 3 in this state is moved as shown by arrow B in Fig. 2a (
When pushed toward the door 2, the pin 8 will engage the pin locking portion 14""
The Y pullout is pulled out and passes through the outward path of the endless groove 14 to the pin locking portion 14' as shown by the broken line X in FIG.
It is locked there by the action of , and the state as shown in FIG. 2 is obtained.

As the pin 8 moves in the endless groove 14 as described above, the swinging member 12 easily swings under the force from the pin 8 or the spring 24, thereby controlling the movement of the pin 8 in the endless groove 14. I have to.

In the state shown in Figure 2, the front surface 4 of the pusher 3 is flush with the front end surface of the decorative ring 25 so that it does not become an obstruction at all.

When the finger 3 in the state shown in Figure 2 is pressed, the pin 8 is released from the pin locking part 14' and is moved back through the endless groove 14 by the action of the spring 1, as shown by the broken line Y in Figure 2. It passes through and locks into the pin locking portion 14'', returning to the state shown in FIG. 2a.

As shown in FIGS. 1 and 2 a and b, a locking member 17 operated by a handle 3 is swingably attached to a casing 27, and a forked portion 19 into which a pin 8 is fitted is attached to the shaft portion 18. A locking pawl 20 is also provided.

When the handle 3 is in the protruding state, the locking pawl 20 is in the casing 27, and when the handle 3 is in the retracted state, the locking pawl 20 protrudes through the opening 28 of the casing 27 and the door 2
The claw receiver of the fixed side frame 29 that comes into contact with is made to come into contact with the part.

A shaft hole 21 is formed in the shaft portion 18 of the locking member 17, and a pair of upper and lower connecting rods 23, 23 are fixed to this shaft hole 21.
Locking hooks 22.22 are attached to these ends, and these locking hooks 22.22 are connected to locking pins 32.22 provided on the fixed upper frame 30 and the fixed lower frame 31, as shown in FIG.
32, the locking claws 20 are adapted to lock in conjunction with the claw receivers of the fixed side frame 29.

Next, the operation of the device will be explained.

In order to close the door 2, it is preferable to press the pusher 3 that protrudes from the door 2.

As described above, the locking pawl 20 is
The fixed side frame 29 is swung as shown by arrow C, and the claw receiver of the fixed side frame 29 is engaged with the part, and the hook 22 is engaged with the engagement pin 32.

Door 2 is completely fixed and will not open by itself.

In this locked state, the front surface 4 of the handle 3 is flush with, or almost flush with, the front surface of the door 2, so the pusher 3 does not get in the way (see Figure 2).

Door 2y! - To open, just press the handle 3 in the retracted state.

Along with this movement, the pusher 3 protrudes from the door 2, and the locking claw 2
0 is removed from the fixed side frame 29, and the locking hook 22 is removed from the locking pin 32.

Therefore, the finger of the protruding pusher 3 is placed in the recess 9 of the door 2.
The door 2 can be easily opened by pulling it.

According to this invention, the handle 3 is provided so that it can move forward and backward with respect to the door 2, so when the door 2 is closed, the handle 3 is moved back and forth, so that it does not get in the way. In addition to making the appearance of the door 2 neat and beautiful, the handle 3 is made to protrude when the door 2 is opened, and the finger rest formed on it allows you to place your finger in the recess 9. Door 2 can be opened extremely easily.

Furthermore, when the handle 3 is retracted into the door 2, the locking member 11 is in the locked position and remains in that state unless the handle 3 is pressed, so the door 2 does not open automatically.

Furthermore, either the member 12 having the endless groove 14 or the pin 8 is configured to swing in a direction transverse to the center line of the handle 3 in the advancing and retreating direction.

The pin 8 can be guided smoothly along the endless groove 14.
