Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved vending machine lock and bar member mounting jig used in vending machines and the like.

[0002]

2. Description of the Related Art Generally, in conventional vending machine locks used in vending machines and the like, the bar members are engaged only with the handle case and not with the inner case bolt. Further, when unlocking, the tip of the protruding barb member protrudes while coming into contact with the inner circumference of the handle case, so that the operation of the handle tends to be heavy.

[0003]

By the way, in the conventional vending machine lock described above, since the barb member slides while contacting the inner circumference of the handle case, when the amount of protrusion of the handle is insufficient, the handle is operated. Was a cause of heavy weight. In addition, since the engagement between the bar members and the handle case is shallow, there is a possibility that the engagement may be disengaged due to vibration or the like. Furthermore, since the handle case has holes for engaging the bar members from the rear side, the waterproof function is not perfect, and it is unsuitable for a vending machine that sells products such as cigarettes that are easily affected by moisture. There was a drawback. In addition, the waterproof mechanism using the packing member has a drawback that the rotation of the handle is uncomfortable. Furthermore, the number of parts is large and the manufacturing cost is increased.

The object of the present invention was made in view of the above-mentioned drawbacks of the prior art. The object is to reduce the number of lock parts, and
An object of the present invention is to provide a vending machine lock that has a smooth handle and is highly waterproof.

[0005]

A vending machine lock according to the present invention has a handle case fixed to the door side of the vending machine with a screw or the like, and is rotatably mounted in a cylindrical portion of the handle case. An inner case bolt, a handle that is housed in the inner case bolt and is spring-biased so as to project outward, a lock attached to the front surface of the cylindrical body of the handle, and an inner cylinder of the lock. A barb member that rotates within the tubular portion of the handle with rotation, and the barbular member is rotated by the inner tube to move from the engaging groove formed in the inner case bolt to the sliding groove. The handle is projected by the spring. The handle case and inner case bolt are provided with irregularities to enhance waterproofness. In addition, a barb member attachment characterized by having a substantially circular mounting groove in the center and engaging projections on both sides, and having a bottom and a top formed in an arc shape to be mounted on the shaft of the barb member for use. It is a jig.

[0006]

As described above, according to the lock for a vending machine according to the present invention, it is possible to increase the strength of the lock in which the barb member engages with both a part of the handle case and a part of the inner case bolt. . Further, since the tips of the bar members do not come into contact with the inner circumference of the handle case when unlocked, the handle can be operated smoothly.

As a waterproof measure, since the packing is not incorporated, the rotation of the handle does not become uncomfortable and the waterproof property can be improved.

Further, the workability can be improved by preventing the bar member from being biased to one side or dropping by the mounting jig and holding the bar member at the central position during the replacement of the lock by a mounting jig. .
