Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a case lock attached to a trunk, an attache case or the like, and more particularly to a lock device for a case lock.
[0002]
[Prior art]
A utility model registration No. 1523751 (Japanese Utility Model Publication No. 58-17092) exists as a conventional case lock. This conventional case lock has a drawback that the lock body is bulky due to the structure in which the key is inserted into the keyhole from the top during locking and unlocking, and the locking and unlocking indications are not clear and handling is uncertain. .
[0003]
[Problems to be solved by the invention]
An object of the present invention is to provide a lock device for a case lock that can form a lock body thinly, and that clearly displays the locked and unlocked state and is easy to use.
[0004]
[Means for Solving the Problems]
Means of the present invention are as follows. A thin lock body provided with a base plate fixed to the case main body and an operation member pivotably attached to the rear end of the base plate by a shaft, and a locking rod attached to the lock body on the case lid side. An engagement plate for engaging and disengaging is formed, and an insertion hole for inserting the key from the side is formed, and when the key is inserted into the insertion hole of the lock body, the insertion hole is blocked against the spring. The shutter pivoted on the main body can be pushed and a key can be inserted, and the operation member of the lock body has an outer cylinder and an inner cylinder, and the inner cylinder slidably mounted on the outer cylinder with a key. An L-shaped bracket is attached to the inner cylinder with a pin, a rotor that is rotated by the L-shaped bracket is provided integrally with the shaft, and the inner cylinder moves by inserting the key, The rotor is rotated 90 ° by an L-shaped bracket attached to the inner cylinder with a pin. In this case, by writing inserted the key, shaft integral T Katachitomehen rotors engaged with the engaging hook portion formed on the substrate is engaged the operating member to the substrate, during the unlocking In this case, the T-shaped stopper piece is disengaged from the locking hook portion by inserting a key, the operating member is released from the substrate, and a lock display window on the surface of the operating member formed on the lock body on the rotor. A lock device for a case lock, characterized in that a color display portion for displaying in one of a hole and an open display window hole is formed.

DETAILED DESCRIPTION OF THE INVENTION
The general configuration of the case lock to which the locking device of the present invention is applied is the same as that of the known utility model, and the novel features of the present invention including this structure will be described below.
In the figure, reference numeral 1 denotes a lock body which is attached to the trunk main body. Reference numeral 2 denotes a locking rod fixed to the lid of the trunk. The lock body 1 is pivotally supported by a shaft 3 at the rear end of the fixed substrate 1a so as to be openable and closable, and is provided with an operation member 1b. When unlocked with the shaft 3 as a fulcrum, as shown in FIG. The locking plate 1 is unlocked by moving the engagement plate 5 having the spring 4 applied thereto.
[0006]
In the present invention, a novel 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 pushed and moved by a key K. An L-shaped metal fitting 9 is attached, and the rotor 10 rotated by the L-shaped metal fitting 9 is provided with a shaft 11 integrally, and open and locked color display portions 12 and 13 are provided at positions facing the periphery of the rotor 10 in close proximity. An open display window hole 14 and a lock display window hole 15 are opened on the upper surface of the operation member 1b of the lock body 1 (see FIGS. 1 and 9), and the coloring display section 12 is alternately turned by 90 ° rotation of the rotor 10 by the key K. Alternatively, when the color display unit 13 matches the open display window hole 14 or the lock display window hole 15, the open and locked states are displayed.
[0007]
When the T-shaped stopper piece 16 integrated with the shaft 11 of the rotor 10 is locked to the locking hook 17 formed on the substrate 1a, the lock body 1 is fixed to the substrate 1a and cannot be unlocked (see FIG. 11 and FIG. 12), and the T-shaped stopper 16 can be unlocked when the locking collar 17 is removed (see FIGS. 3 and 7). In FIG. When the spring 21 is acted on the lever shaft pivotally supported on the lock body 1 together with the lever 20, and the lever 20 is pulled up against the spring 21, the distal end flange portion 22 of the substrate 1a is disengaged, and the operation member 1b is moved about the shaft 3 as a fulcrum. Unlock as shown in FIG.
[0008]
When the key K is inserted into the insertion hole 23 of the lock body 1, the shutter 18 that has blocked the insertion hole 23 against the spring 21 can be pushed lightly and the key K can be smoothly inserted. Further, as shown in FIG. 3, the inner cylinder 7 is fixed to the outer cylinder 6 by a plurality of pin tumblers 24 , 24 , and although not shown in the drawing, the groove provided on the back surface of the key K matches the pin tumbler 24. Unless the key K is inserted, the inner cylinder 7 cannot be moved. In the figure, reference numeral 25 denotes an upright piece of the substrate 1a which is pivotally attached to a limiting piece 27 attached to the lock body 1 by a pin 26 .
[0009]
[Action]
When the key K is inserted into the insertion hole 23, the rotor 10 is rotated by 90 °, and when the coloring display portion 12 or 13 appears from the open display window hole 14, the T-shaped stopper 16 of the rotor 10 is locked to the substrate 1a. The operation member 1b can be unlocked by removing it from the flange portion 17 as shown in FIG. 6, and in this state, the operation member 1b is closed and locked, and a key K is inserted to further rotate the rotor 10. When the colored display portion 12 or 13 appears through the lock display window hole 15 after being rotated by 90 °, the T-shaped stopper piece 16 is locked to the locking collar portion 17 of the substrate 1a and locked in the locked state, so that it is unlocked. I can't.
[0010]
【The invention's effect】
According to the present invention, since the key is inserted from the side, the lock body can be formed thin. In addition, since the open and locked states are displayed, the locked and unlocked states become clear and the usability is good.
