And a flanged ring 8 made of a rigid metal is fixed to a front portion of the lock unit 7.

Description

[Detailed description of the invention]

[0001]

TECHNICAL FIELD The present invention relates to protection of a lock unit in a pop-out type lock handle device used for a door of a vending machine or the like.

[0002]

2. Description of the Related Art Since a conventional handle containing a lock unit is made of die-cast aluminum or zinc alloy, it is relatively vulnerable to cutting. Therefore, by cutting the periphery using a hole saw (a rotary cutting tool) with a diameter slightly larger than the lock, the mounting bracket that attaches and holds the lock unit to the barrel of the handle is cut, and the lock unit is removed. I will be. As a result, an unauthorized person can easily unlock and open the door.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a pop-out type lock handle device which is robust so that the periphery of the lock unit is not scraped off and which does not require much improvement cost.

[0004]

The pop-out type lock handle device of the present invention will be described below with reference to the reference numerals in the accompanying drawings. The inner cylinder 3 is mounted so as to be rotatable and movable back and forth, a locking member 4 is connected to the rear surface of the inner cylinder 3, and the shaft portion 5 a of the handle 5 is rotatably and slidably moved forward and backward within the inner cylinder 3. The lock unit 7 is inserted into the inner cylinder 3 to be urged forward by the spring 6, and the lock unit 7 is inserted into the inner cylinder 3 and fixed to the inner cylinder 3 by the mounting bracket 10, and a flanged ring made of a rigid metal is provided on the front part of the lock unit 7. 8 is fixed.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In the illustrated embodiment, the flanged ring 8 is made of a hardened steel or a special metal which is hard as a material. A female screw 9 is cut on the inner peripheral surface of the front end portion of the lock receiving portion of the inner cylinder 3, and a male screw 12 screwed to the female screw 9 is cut on the outer peripheral surface of the flanged ring 8. The diameter of the front end flange of the flanged ring 8 is sufficiently larger than the diameter of the lock unit 7, and is set so that all or most of the mounting bracket 10 is hidden behind.

Since the flanged ring 8 is fixed to the inner cylinder 3 by screwing in, the outer peripheral surface 8a of the flanged portion of the flanged ring 8 has a front surface in order to prevent the flanged ring 8 from being detached by turning in the reverse direction. It is formed on a tapered surface whose diameter decreases toward the side. For this reason, even if the user tries to grip the flange with the tip of a tool such as a pliers, the tip of the tool slips, and the collar ring 8 cannot be turned. If a recess is formed in the front surface of the inner cylinder 3 so that the flange of the flanged ring 8 sinks, the rotating operation becomes more difficult.

[0007] An external thread 13 is cut over the entire outer surface of the fixed main body of the lock unit 7 except for a front end flange 7a, and a base ring 15 having an internal thread 14 on an inner peripheral surface is provided with a front end flange 7a. Screwed into contact with the back of Two annular receiving grooves 16 are provided on the outer peripheral surface of the base ring 15. The U-shaped mounting bracket 10 inserted from the side direction into the diametrical receiving hole 18 of the inner cylinder 3 has two locking projections 17 on the inner surfaces of the two legs, respectively. By fitting the locking projection 17 into the annular receiving groove 16 of the base ring 15, the lock unit 7 is prevented from being pulled out forward. Since the configuration and operation of the pop-out type lock handle device other than the above are well known, the description and illustration are omitted.

[0008]

[Effect of the Invention] As described above, in the present invention, the ring-shaped ring 8 made of a solid metal is fixed to the front part of the lock unit 7, so that the storage part and the peripheral part of the lock unit 7 are fixed by a hole saw or the like. It was impossible or almost difficult to cut and the security performance was greatly improved. Also, the entire handle 5 is not made rugged, but it is made rugged so that the security effect can be obtained only at the required minimum specific parts. Therefore, the amount of expensive rugged members used is suppressed, and the increase in improvement cost can be suppressed. it can.
