Abstract

PROBLEM TO BE SOLVED: To provide a device preventing a breaking by using a drill of a key hole for an automatic vending machine or the like. SOLUTION: A cone cap 4 made of a hard metal is installed at the end of a lever 3 capable of being rotated centering around a shaft 5, and the key hole is covered at all times. An alarm is sounded as soon as a burglar removes the cap 4 for using a drill. When a hand is detached, the cap is returned to an original place by the elastic force of a spring 13, and the alarm is stopped. The alarm is also sounded even when the lever is wrenched open by using a lever.

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a technique for preventing breakage of a keyhole of a vending machine or the like installed outdoors. 2. Description of the Related Art There has been a frequent crime of breaking a lock by inserting a drill blade into a keyhole of a vending machine, and in order to prevent this, a door is chained or a lock is made of hard metal. ,
Measures such as attaching multiple locks were taken. [0003] These have the following drawbacks. B Thick chains are easily broken. B. Locks made of hard metal can also be broken with a drill. C. If there are multiple locks, it takes time to break them, so they seem to be a little hesitant or have to do it in a deserted place. The present invention has been made to solve the above drawbacks. [0004] The keyhole is always covered with the lever (3) so that a pirate cannot use the drill even if he tries to break the lock. A hard cone cap (4) is attached to the part covering the keyhole. An insulator disc (7) is attached to the shaft (5) of the lever (3), and a contact plate (8) attached to the surface of the insulator disc (7) has a notch (8a) and a contact piece (1).
2a) and the contact piece (12b) constitute an alarm transmission switch. Further, an insulator disk (7) is formed by using a spring (13).
Pull the pin (10) so that the cap (4) is always directly above the keyhole. The present invention is a keyhole destruction prevention device having the above configuration. [0005] Embodiments of the present invention will be described below. (B) A bearing (6) for passing the shaft (5) of the lever (3) is attached beside the lock (2). (B) The hard metal cone cap (4) attached to the end of the lever (3) covers the keyhole of the lock (2). (C) A notch (8a) of several millimeters is made in the contact plate (8) in which a thin donut-shaped copper plate is pasted on the insulator disk (7). (D) Notch (8a) near the outer periphery of the insulator disk (7)
A spring hook pin (10) is set up on a portion corresponding to the back side of the. (E) Hang the end of the spring (13) on the spring hook pin (10), pull in the opposite direction to the lock (2), and fix the other end to the spring hook (14) of the door plate (1). (F) When the cap (4) is positioned right above the keyhole, the lock screw (9) of the insulator disk (7) is tightened. (G) The contact piece (12a) is adjusted so that the contact point of the contact piece (12a) comes to the center of the notch (8a), and the contact piece holding plate (11) is fixed to the door plate (1). (H) The contact of the contact piece (12b) is fixed so as to be on the opposite side of the contact piece (12a) across the shaft (5), and a slight gap is formed between the contact piece (12b) and the contact plate (8). . (I) An alarm stop switch (16) necessary for management is provided. The present invention has the above configuration. With the present invention, even if a pirate tries to break the lock, the cap (4) is in the way and the drill cannot be used. Therefore, when the cap (4) is moved in order to retreat, an alarm is sounded immediately. If you let go, the cap will return to its original position and the alarm will stop, but the bandits will give up and go away without repeating this. Some might use levers to pry up lever (3). Therefore, it is necessary to make the lever (3) and the shaft (5) firmly. However, if the lever (3) is pryed up, the shaft (5) tilts, and the contact plate (8) becomes the contact piece (12b). Raise an alarm by touching. The reason why the hard metal cone is used for the cap (4) is to prevent the drill blade from slipping and making a hole with the cap. When an administrator opens or closes a door, the alarm circuit must be turned off. For this purpose, a key switch may be used, but there is also a fear that this may be broken by a drill. Then, it came up to use the switch matrix shown in FIG. When a matrix is formed by five switches from a to e, 32 states can be obtained.
FIG. 4 shows one of the states, which is 01011 in binary. At this time, the contact of the relay (20) is opened and the connection between X and Y is cut off. To change the binary number, an auxiliary switch may be used. Even if the switches a to e are broken, no abnormality occurs in the alarm circuit. Therefore, it can be said that the switch matrix system is one of the inexpensive and secure systems. According to the present invention, damage to a vending machine or the like can be prevented. The alarm stops in a short time and does not bother the neighbors. In addition, since the administrator employs a matrix for the switch for stopping the alarm, the alarm circuit operates normally even if the switch is broken. If an auxiliary switch is used,
You can also change the radix. From these, the present invention was able to improve the safety and reliability of the vending machine. If a vending machine is destroyed, the damage to the sales and tobacco products will be enormous, as well as the damage to the vending machine itself. Recent vending machine trolls have become professional, and the criminal arrest rate is poor.
Victims have no choice but to cry and sleep at all times, feeling frustrated. In light of this situation,
It is believed that the present invention for preventing damage can meet the long-awaited needs in the art. Further, the present invention can be applied to, for example, anti-picking locks other than vending machines.
