Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a padlock button device in which the lock is unlocked by pressing a plurality of button buttons.

Conventionally, in this type of padlock, the lock is unlocked by rotating a ring to set a code combination, or by pressing a Pnonyu button to set a code combination.

In particular, with code-combined padlocks using button buttons, the button that has been pushed remains pressed in and immersed in the padlock case unless the button is locked. The drawback is that there is a risk that the lock number may be stolen, making it impractical.

The purpose of the present invention is to eliminate this drawback, and the object of the present invention is to make the button that is pushed to unlock the door temporarily recessed, but can be restored immediately when the button is released.

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

In the present invention, the button is provided with a spring between the button case and the movable element, and by pressing the button configured as described above, the button case and the movable element are temporarily moved from the center to the center. The padlock is pushed into the lock case, but when the button case is released, it immediately returns to its original position, but the mover remains in the unlocked position until the padlock is locked. This is a button device, and the gist thereof is as set forth in the claims above.

An embodiment of the present invention will be described below with reference to the drawings.

1 is a perspective view of the present invention, in which a latch 2 bent into an inverted U-shape is fitted into the upper part of a case 1.

As can be seen in the split perspective view of FIG. 2, this latch 2 has a shorter length 10,000 2a, while the other 2C has a longer length.

In addition, on the front surface of the case 1, a plurality of (10) button case 3 protruding from the case 1, which serve as buttons. Further, an unlocking button 4 is provided in parallel with the push button case 3, which starts unlocking when the code to be unlocked is correctly suppressed.

Oh. 11, 70. ．． . □Thia□2゜　.

This will be explained with reference to FIGS.

In FIG. 2, a plurality of small holes 1a and square holes 1b are formed in the front wall surface 1' of the case 1, and two holes 1c,
Drill the ld. The head portions of pushbutton cases 3 of the same number as the small holes 1a are fitted, and the flanges 3a formed on the pushbutton cases 3 abut against the inner wall surface of the case 1 to prevent them from coming off from the case 1.

Further, a spring S is fitted inside the button case 3, and this spring S is fitted into each of the four parts 4' formed on the movable element 4 and the non-movable element 5. Notches 4a are formed on the side surfaces of the movable element 4 and the non-movable element 5, and
Neck portions 4c and 5b are formed at the tip.

In one embodiment of the present invention, there are four operation buttons out of ten, that is, unlock operation buttons, so the notches 4a formed in four of the plurality of buttons and the remaining six are opposite to each other. In this position, the notches 5a of the six non-movable elements 5 are in the unlocked position, and when the non-movable elements 5 are moved, the necks 5b of the non-movable elements 5 are always held between the two elastic wires 6 and are in the locked state.

Therefore, these six items must not be operated when unlocking.

塘, unless the remaining four movers 4 are suppressed,
It is always in the locked position, and at this time the side portion 4b of the movable element 4 is engaged with the side edge 7.' of the notched sliding piece 7.

Therefore, when unlocking, the notch 4 of this movable element 4 is
When a is moved to the side edge 7' of the sliding piece 7, the sliding piece 7 becomes movable.

A bent piece 7a is formed at the end of this sliding piece 7, and a protruding piece 7b is connected from this bent piece 7a. This bent piece 7
The protruding rod 8 formed at the rear end of the unlock button P is placed on a, and the protruding piece 7b is formed on the latch 2! 7 tsuba part 2
A is engaged. Also, the unlock button P is always in case 1.
It is pressed by a spring S+ so that it protrudes to the outside.

A fixed plate 10 with a plurality of long holes 9 formed on the back side of the sliding piece 7
When set, the movable element 4 and the non-movable element 5 move forward and backward within the elongated hole 9.

Further, a vertically movable plate 11 is provided on the back side of the fixed plate 10, and an inclined surface 11a is formed on the inner wall surface side. And this inclined surface 11a
Grooves 11b into which the wire rod 6 is fitted are formed on both edges.

Furthermore, the upper V protrusion 11 on the side wall surface of the lower moving plate 1]
c is formed 17, and the tip 2b of the latch 2 presses down this protrusion 11C when locking. A protrusion 1.1 d is formed at a position facing the protrusion 11C of the vertically movable plate 11, and a spring S3 is provided between this protrusion lid and the case 1, so that the vertically movable plate 11 is always It is forced to push up.

12 is the back cover of the case 1, and a spring S2 for pushing up the latch 2 is accommodated in a groove 13 formed in the back cover 12, and this spring S2 is fitted into one end 2C of the latch 2. .

Since the structure is pressed as described above, the non-movable -r5 is in the unlocked position 17 at the time of manufacture.

In other words, the non-movable element 50 holder 5b is held between the wire rods 6 12
Since the notch 5a of the non-movable element 5 is located on the side edge 7' of the sliding piece 7, when the push button case 3 that presses the remaining four movable elements 4 is pressed, the movable element 4 is pressed. The neck 4C of is held by the wire 6, but the push button case 3
is returned to the outside of the case 1 by a spring S.

Moreover, the notch portion 4a of the movable element 4 and the non-movable element 5.

5a are both located at the unlocking position, that is, at the side edge 7' of the sliding piece 7. At this time, when the unlocking button P is pushed from the outside of the padlock A against the spring Sl, the unlocking button P is released. At the same time that the protruding piece 8 is disengaged from the bent piece 7a of the vertical moving plate 11, the 1-lower moving plate 11 is raised by the spring S3, and the tip 2b of the latch 2 is released from the case 1 to be unlocked. .

Next, when the latch 2 is locked, that is, when the latch 2 is pushed into the case 1, the tip 2b of the latch 2 pushes down the protrusion 11C of the vertically movable plate 11 against the spring S2. At this time, the inclined surface 11a of the vertically movable plate 11 slides on the tip of the movable element 4 and returns the movable element 4 to its original position, so that the next unlocking operation can be performed in one operation.

As described above, the present invention has a spring interposed between the push button case and the movable element and the non-movable element, so even when pressed, only the push button case is temporarily pushed in, but immediately returns automatically. Therefore, unlock 1. Tama 1. Even if you leave it unattended, there is no risk of your unlock code being known, so it has an extremely large practical effect. 1.
