Abstract

PROBLEM TO BE SOLVED: To thin a lock main body, and to clarly display locking/unlocking by arranging coloring display parts displayed on one of lock/open display windows of an operation member surface, in a rotor to rotate by 90 deg. by inserting a key into the lock main body. SOLUTION: An inner cylinder 7 to move by a key K is provided in an operation member 1b of a lock main body 1, and a rotor 10 rotates by an L-shaped metal fitting 9 installed in the inner cylinder 7. A shaft 11 is integrally arranged in the rotor 10, and open/lock coloring display parts 12 and 13 are arranged in peripheral opposed positions, and open/lock display window holes 14 and 15 are opened on an upper surface of the operation member 1b. Since the rotor 10 rotates by 90 deg. when the key K is inserted into an inserting hole from the side, the coloring display part 12 or 13 appears from the open display window hole 14, and a T-shaped fastening piece of the rotor 10 slips out of a locking hook part arranged on a base board, so that a lock can be opened by pulling up the operation member 1b. When the coloring display part 12 or 13 appears in the lock display window hole 15 by rotating the rotor 10 further by 90 deg. by inserting the key K by closing the operation member 1b, a lock can be fastened by locking/closing the T-shaped fastening piece by the locking hook part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A case lock provided with the lock device of the present invention has a general structure similar to that of the above-mentioned known utility model, and a new point of the present invention including this structure will be described below. In the drawing, reference numeral 1 denotes a lock body which is attached to a trunk main body. Reference numeral 2 denotes a hook fixed to the trunk lid. The lock body 1 is pivotally supported at the rear end of the fixed substrate 1a by a shaft 3 so as to be openable and closable, and has an operating member 1b. When unlocking the shaft 3 as a fulcrum as shown in FIG. The lock plate 1 is opened by moving the engaging plate 5 with the spring 4 acting on the lock body 1.

In the present invention, a new locking device is provided in the operation member 1b. The operation member 1b of the lock body 1 is provided with an outer cylinder 6 and an inner cylinder 7, and the inner cylinder 7 slidably mounted on the outer cylinder 6 is moved by pressing with a key K. An L-shaped bracket 9 is mounted, and a rotor 10 rotated by the L-shaped bracket 9 is provided with a shaft 11 integrally therewith, and open and locked color display sections 12 and 13 are provided at positions close to and opposed to the periphery of the rotor 10. An open display window 14 and a lock display window 15 are opened on the upper surface of the operation member 1b of the lock body 1 (see FIGS. 1 and 9),
The coloring display unit 12 or the coloring display unit 1 is alternately rotated by 0 °.
When 3 matches the open display window hole 14 or the lock display window hole 15, the open and locked states are displayed.

When the T-shaped stopper 16 integral with the shaft 11 of the rotor 10 is locked on the locking hook 17 formed on the board 1a, the lock body 1 is fixed to the board 1a and unlocked. No (see FIGS. 11 and 12), and can be unlocked when the T-shaped stopper 16 removes the locking hook 17 (see FIGS. 3 and 7). Actuates a spring 21 with a lever shaft that pivotally supports the shutter 18 together with the lever 20 to the lock body 1. When the lever 20 is pulled up against the spring 21, the tip hook portion 22 of the substrate 1a operates with the disengagement shaft 3 as a fulcrum. The member 1a is unlocked as shown in FIG.

When the key K is inserted into the insertion hole 23 of the lock body 1, the shutter 18 closing the insertion hole 23 against the spring 24 is lightly opened to allow the key K to be inserted smoothly. Further, as shown in FIG. 3, the inner cylinder 7 is fixed to the outer cylinder 6 by a plurality of pin tumblers 25, 25. Although not shown in the drawing, a groove provided on the back surface of the key K and the pin tumbler 25 Unless they match, the key K cannot be inserted, and the inner cylinder 7 cannot be moved. 2 in the figure
Reference numeral 6 denotes a standing piece of the board 1a, which is pivotally attached to a limiting piece 28 attached to the lock body 1 by a pin 27.

[0009]

When the key K is inserted into the insertion hole 23, the rotor 1
0 rotates 90 °, and when the color display portion 12 or 13 appears through the open display window hole 14, the T-shaped stopper 16 of the rotor 10.
Is disengaged from the hook 17 provided on the substrate 1a,
6 can be unlocked by pulling it up as shown in FIG. 6. In this state, the operating member 1b is closed and locked, the key K is inserted, and the rotor 10 is further rotated by 90 ° to display the color display section. When 12 or 13 appears from the lock display window hole 15, the T-shaped stopper 16 is locked by the locking hook 17 of the substrate 1a and locked in the closed state, so that it cannot be unlocked.

[0010]

According to the present invention, since the key is inserted from the side, the lock body can be formed thin.
It also displays the open and locked status, so it can be locked,
The unlocked state is clear and the usability is good.
