[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating tool for operating a dial change lever incorporated in a dial combination lock.

[0002]

2. Description of the Related Art A conventional dial combination lock changes the dial number by operating a lever against a spring to make each dial free, and then turning the dial to set the desired number and then returning the lever. It has become. (Refer to Japanese Patent Application Laid-Open No. 55-14528) The above-mentioned lever is an extremely small piece, and must be operated by putting a finger into a notch provided inside the bag, which is very inconvenient in operation.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned disadvantages of the prior art and to provide a change lever operating tool which is easy to operate and makes it very easy to change a dial number.

[0004]

According to the present invention, there is provided a flat operating tool body which is attached to the back of a bag side plate to which a dial lock is fixed on the surface, and has a longitudinal groove having both end faces formed along the longitudinal direction. A slide having an engagement hole into which a change lever protruding from the dial lock and protruding through the measuring plate is housed in the groove, and one end surface of the groove is provided on a guide frame portion integral with the slide. A press knob is provided that is exposed to the outside from the flat hole that is opened at the other end, a coil spring that opposes the pressing direction is interposed between the slider and the other end surface of the groove, and the locking projection provided on the guide frame portion is locked. A slider stopper of elastic synthetic resin is housed in the guide frame, and the slider stopper is
A release protrusion protruding from the hole formed in the bottom surface of the groove to the outer surface of the operating tool body, a bending elastic portion for giving elasticity to the release protrusion, and provided at the tip of the bending elastic portion to form left and right sides of the groove. The notch is formed integrally with a shaft portion pivotally supported by the notch.

When the pressing knob 9 is pressed against the coil spring 10 in the state shown in FIG. 4, the slider 4 moves with the change lever L, and the guide frame portion 5 integrated with the slider 4 engages with the locking projection. 17, the locking projection 17 is elastically locked beyond the slider stopper 11 to stop the slider 4, and the change lever L is pushed until the dial K 'can be changed. Stabilize. (See Fig. 5)
Next, when the release projection 12 is pushed at the position shown in FIG.
The slider 4, the guide frame 5, and the change lever L return to their original positions by the action of the coil spring 10.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawing, reference numeral 1 denotes an operating tool main body formed of a synthetic resin into an elongated flat shape, and a dial lock K is fixed to a back surface of a bag side plate V having a surface fixed thereto. Operation tool body 1
A groove 4 having front and rear end faces 2a, 2b is formed on the inner surface of the slide lock 4, and a slider 4 having an engagement hole 3 into which a dial change lever L protruding from the dial lock K through the side plate V is inserted is formed. 2 and a guide frame portion 5 which fits into the left and right side surfaces 2c and 2d of the groove 2 is integrally connected to the slider 4, and the guide frame portion 5 is provided on the opposite surface of the slider 4 to protrude. Both ends of the coil spring 10 are inserted into the projection 7 projecting from the groove end face 2b, and the tip end of the guide frame 5 is pressed against the end face 2a by the coil spring 10 to make the end face 2a.
Press knob 9 provided in the guide frame 5 from the flat hole 8 formed in
To the outside. Also, the slider stopper 11 is provided in the guide frame 5.
Put in. As shown in FIG. 4, the slider stopper piece 11 is made of a synthetic resin having elasticity, and has a release projection 12, a curved elastic piece 13, and a shaft portion which is pivotally supported by notches 14 formed on the left and right sides of the groove 2. 15 are integrally formed. Release projection 12
Is projected from the hole 16 formed in the bottom of the groove 2 to the outside,
An engagement protrusion 17 for stopping the movement of the slider 4 by hitting the tip of the slider stopper piece 11 is formed at an intermediate portion of the guide frame 5. In the drawing, reference numeral 18 denotes a guide protrusion of the slider guide frame 5 provided on the side surface 2c, 2d of the groove 2.

[0007]

According to the present invention, the change lever L can be easily and surely moved to a position where it can be changed simply by pressing the pressing knob 9. After the change, if the release protrusion 12 is pressed, the change lever L returns to the original position, the dial can be changed smoothly, and the conventional inconvenience in operation can be eliminated.
