The present invention relates to a key release device used to operate the engine or unlock the lock by rotating the key after the key is inserted.

Conventionally, a plurality of high and low inclined surfaces inclined to the end side are formed on both sides of the key so that a plurality of working pieces inclined inclined to the end side are pressed to the inclined plane of the key incision so that the center is unlocked when the center is hit. In this case, the center center is aligned and opened, and the arcuate recess is formed horizontally in the rotational engine, and the recess is inserted into the recess so that the key 10 side groove can be opened by moving the recess. However, this is not possible to manufacture and if the production is a problem such as to be separated because the engine part is to be divided into four equal parts.

The present invention is to solve the problems described above to form a bent groove on the upper and lower surfaces in the central portion of the key, and to form a curved protrusion of a size that can be inserted into the groove in the center of the top plate, the curved groove of the key The purpose of this is to prevent the key from being opened because a plurality of top plate curved protrusions can be opened only when they are inserted in the top and bottom positions, and wires, skewers, and similar keys cannot move the multiple top plate curved protrusions in place. When described in detail based on the accompanying drawings as follows.

In the key that rotates and releases, the release plate (4) (4 ') formed with the spring (12) engaging jaw (6) and the key insertion hole (8) has a curved protrusion (5) at the center of the key insertion hole (8). And the curved projections 5 are inserted into the operation holes 11 and 11 'of the key body 9 in an up and down direction alternately, and the locking groove 13' is formed thereon. 13) and the cap of the tracheal cap 10 to be fixed and inserted into the center portion of the upper and lower planes so as to be able to release the key (1) formed with the bent groove (2) to enlarge the inlet (3) greatly. It is a key release device.

Reference numerals 14 and 14 'are the engine operation parts, and after the key insertion, all the unlocking plates are in a straight line, that is, all the locking plates mounted on the key body 9 are not caught by the locking recess 13' of the locking cap 13. When the key is turned, the engine and other engines are operated by turning the operating part to rotate, and 17 is to turn the top plate 4 over and insert it into the key body (engine part) 9 and the operating hole 11 in the opposite direction. It is a snowboard in the snowy state.

Looking at the operation and effects of the present invention configured as described above are as follows.

A plurality of locking plates 4 to be caught by the latching jaws 6 and 6 'while holding the spring 12 against the plurality of operating holes 11 and 11' formed in the rotary key body 9 such as a circle. Alternately insert (4 '), i.e. insert one with the protrusion (5) on the upper side and one insert with the inverted side on the right side, so that the protrusion (5) is on the opposite side of the lower side) (10) and the locking cap (13) to cover the locking plate (4 (4 ') is not separated and separated, while the left and right sides of the locking plate (4) (4') locking plate (7) (7 ') locking cap ( 13, the locking groove 13 is inserted into the recess, so that the key body 9 is locked in the locked state. When the key 1 is inserted, the curved groove 2 of the key 1 enters ( 3) is widely formed, the curved protrusions 5 and 5 'of the top plate 4 and 4' at any position are also guided and inserted into the curved recesses 2 of the key 1 Release plate (4) (4 ') according to the state of the groove (2) ) As the curved protrusions 5 and 5 'are inserted and placed, a plurality of curved protrusions 5 and 5' are moved to the position of the center center (the spring 12 is stretched and contracted) (4 '), both sides of the locking plate (7) (7') side is moved in the state coinciding with the key body (9) operating holes (11) (11 '), that is, the unlocking plate (4) (4') Since the locking portions 7 and 7 'of the locking cap 13 are not caught by the locking recess 13' of the locking cap 13, the key 1 and the key body 9 can be rotated, and the key 1 is rotated. Then, the engine operation part 14 (14 ') which protrudes on the end side of the key body 9 is caught and rotated by the engine to be rotated, so that the engine is operated (started) or released.

The present invention as described above is a very useful design that is simple in construction and prevented from being released by wires, skewers or similar keys.

Claims (1)

In the key release device, a curved protrusion 5 is placed at the center of the key insertion hole 8 of the release plate 4 and 4 'on which the spring 12 locking jaw 6 and the key insertion hole 8 are formed. The locking cap 13 is formed by inserting the curved protrusion 5 into the operating holes 11 and 11 'of the key body 9, which is a rotating engine part, by shifting the upper and lower parts alternately, and forming the locking groove 13'. And the engine cap (10) is fixed to the key, the key (1) is formed in the groove groove (2) in the upper and lower sides of the groove groove inlet (3) to widen the key body (9) inlet ( 3) A key release device that can be unlocked when inserted in
