Description

  The present invention relates to a locking device for a vending machine excellent in disaster response that can be used as a supply source of beverages and foods when a large-scale disaster such as an earthquake occurs and a local lifeline stops.

In the event of an emergency where a large-scale disaster occurs and lifelines such as electricity, gas, and water supply stop, it is conceivable to provide victims with beverages and food stored in vending machines. However, even if money is inserted into the vending machine at the time of a power outage, the product cannot be purchased, and a key is required to open the door. For this reason, there exists a problem that the drink and food stored in the vending machine cannot be promptly provided to the victim.
Therefore, in the event of an emergency, a vending machine equipped with an emergency regulation release member that can be operated from the outside through an opening closed by a synthetic resin panel, such as a product sample chamber or advertisement display section provided on the outer door Has been proposed. This emergency regulation release member enables the opening of the outer door by directly moving the slide plate engaged with the door locking member in the disengagement direction without operating the lock (for example, (See Patent Document 1).

JP 2008-003845 A

In the vending machine equipped with the above-mentioned conventional emergency regulation release member, the door can be opened without using a key, so that anyone who knows the structure can always release the emergency regulation from the opening. There is a problem that the door can be opened by operating the member. Moreover, it is difficult to make the emergency unlocking possible by changing the structure of an existing vending machine that does not include such an emergency regulation releasing member.
Therefore, the invention according to this application can be unlocked with an emergency key in the event of a disaster, etc., but once the unlocking operation is performed with the emergency key, the emergency key cannot be removed and locked. An object of the present invention is to provide a locking device for a vending machine that can be realized and the fact of emergency unlocking is reliably left behind.

Hereinafter, the present invention will be described with reference to the accompanying drawings, but the present invention is not limited thereto.
In order to solve the above-mentioned problem, a vending machine locking device according to the present invention includes a pin tumbler lock 1 and two types of keys 4 for emergency and emergency use for locking and unlocking the lock 1. It consists of five. The cylinder case 2 of the lock 1 is cylindrical and has a plurality of driver pin holes 2b that extend in the radial direction and open to the inner peripheral surface 2c. The plug 3 in the cylinder case 2 has a columnar shape, and the outer peripheral surface 3a is in sliding contact with the inner peripheral surface 2c of the cylinder case 2, and can be rotated about the axis between the locked position and the unlocked position. The plug 3 includes a key hole 3b that opens at the front end and extends in the axial direction, and a plurality of cord pin holes 3c and 3d that penetrate from the outer peripheral surface 3a to the key hole 3b at positions corresponding to the driver pin holes 2b. The driver pin 6a for locking is movably inserted into one driver pin hole 2a, and is urged toward the inner peripheral surface 2c of the cylinder case 2. The driver pin 6b is movably inserted into the other driver pin hole 2b and is urged toward the inner peripheral surface 2c of the cylinder case 2. The locking cord pin 8a is movably inserted into one cord pin hole 3c, and the cord pin 8b is movably inserted into the other cord pin hole 3d. When the plug 3 is in the unlocked position, the driver pin hole 2a into which the lock driver pin 6a is inserted and the cord pin hole 3c into which the lock cord pin 8a is inserted communicate with each other, and the lock driver pin 6a As a result, the locking cord pin 8a is urged in the direction of the key hole 3b. The service key 4 includes a pin operation part 4a and a closing part 4c. When the service key 4 is inserted into the keyhole 3b, the pin operating portion 4a causes the contact surface between the cord pin 8b and the driver pin 6b to coincide with the outer peripheral surface 3a of the plug, and the closing portion 4b is provided with the locking cord pin 8a. Is closed, and the contact surface between the locking driver pin 6a and the locking code pin 8a is made to coincide with the outer peripheral surface 3a of the plug 3 at the unlocked position. The emergency key 5 includes a pin operation portion 5a and a lock recess 5b. When the emergency key 5 is inserted into the keyhole 3b, the pin operating portion 5a causes the contact surface between the cord pin 8b and the driver pin 6b to coincide with the outer peripheral surface 3a of the plug 3, and the lock recess 5b is in the unlocked position. In FIG. 2, the locking cord pin 8a is allowed to protrude into the key hole 3b. As a result, when the lock 1 is unlocked using the emergency key 5, the locking code pin 8 a protrudes into the locking recess 5 b at the unlocked position, and the rotation of the plug 3 and the removal of the emergency key 5 are prevented. The

  According to the vending machine locking device of the invention according to this application, the door is opened only once for a specific vending machine using an emergency key possessed by an administrator residing in the vicinity of the installation location of the vending machine. Once unlocked, the emergency key cannot be removed and locked by it. For this reason, the fact of an emergency unlocking can be left reliably. While maintaining the security of the lock device, it is possible to improve the ease of use of the vending machine in an emergency. By simply replacing the lock, the existing vending machine can be easily changed to an emergency unlocking type without any other modifications.

Embodiments of the present invention will be described with reference to the drawings.
A lock device for a vending machine includes a lock 1 including a cylinder case 2 and a plug 3, and two types of keys 4 and 5 for regular and emergency operations for operating the lock.

  The cylinder case 2 is substantially cylindrical and has a plurality of driver pin holes 2a and 2b. The driver pin holes 2a and 2b are provided in a plurality of rows side by side in the front-rear direction (left and right in FIG. 4), each extending in the radial direction of the cylinder case 2 and opening in the inner peripheral surface 2c.

  The plug 3 is cylindrical and is inserted into the cylinder case 2 so as to be rotatable about its axis so that the outer peripheral surface 2a is in sliding contact with the inner peripheral surface 2b of the cylinder case 2, and the lock position (FIG. 1, 90) between the unlocking position (FIGS. 3 and 6).

  The plug 3 has a key hole 3b and a plurality of code pin holes 3c and 3d. The key hole 3b opens at the front end of the plug 3 and extends in the axial direction. The code pin holes 3c and 3d extend in the radial direction from the outer peripheral surface 3a of the plug 3 and penetrate the key hole 3b at positions corresponding to the driver pin holes 2a and 2b.

  The driver pins 6 a and 6 b are movably inserted into the driver pin holes 2 a and 2 b of the cylinder case 2, respectively, and are urged by the spring 7 toward the inner peripheral surface of the cylinder case 2. The driver pin 6a is a single locking driver pin.

  Code pins 7a and 7b are movably inserted into the code pin holes 2c and 2d of the plug 3, respectively. The cord pin 7a is a single cord pin for locking.

  One locking driver pin 6 a is movably inserted into one driver pin hole 2 a and is biased toward the inner peripheral surface 2 c of the cylinder case 2. The driver pin 6b is movably inserted into the plurality of other driver pin holes 2b and is urged toward the inner peripheral surface 2c of the cylinder case 2.

  One locking cord pin 8a is movably inserted into one cord pin hole 3c, and the cord pin 8b is movably inserted into the other plurality of cord pin holes 3d.

  The driver pin hole 2a and the cord pin hole 3c are arranged to communicate with each other when the plug 3 is in the unlocked position. Therefore, when the plug 3 is in the unlocked position, the locking cord pin 8a is urged toward the key hole 3b by the locking driver pin 6a.

  The service key 4 includes a pin operation part 4a and a closing part 4c. As shown in FIG. 2, in the locked state, when the service key 4 is inserted into the keyhole 3b, the pin operation portion 4a causes the contact surface between the cord pin 8b and the driver pin 6b to coincide with the outer peripheral surface 3a of the plug. Thus, the plug 3 can be rotated in the unlocking direction. The closing portion 4b closes the cord pin hole 3c, thereby preventing the locking cord pin 8a from entering the key hole 3b in the unlocking position shown in FIG. 3, and the locking driver pin 6a and the locking cord. The contact surface with the pin 8 a is matched with the outer peripheral surface 3 a of the plug 3. Even if the service key 4 is pulled out from the keyhole 3b in the unlocked position, the contact surface between the lock driver pin 6a and the lock code pin 8a and the contact surface between the code pin 8b and the driver pin 6b are plugged by reinsertion. The plug 3 can be rotated in the locking direction by matching the outer peripheral surface 3a.

  The emergency key 5 includes a pin operation unit 5a having the same code as the service key 4 and a lock recess 5b. As shown in FIG. 5, when the emergency key 5 is inserted into the keyhole 3b in the locked state, the pin operating portion 5a causes the contact surface between the cord pin 8b and the driver pin 6b to coincide with the outer peripheral surface 3a of the plug 3. The plug 3 can be rotated in the unlocking direction. Further, the locking recess 5b allows the locking code pin 8a to protrude into the key hole 3b at the unlocked position shown in FIG.

  That is, as shown in FIGS. 5 and 6, when the lock 1 is unlocked using the emergency key 5, the locking code pin 8a protrudes into the key hole 3b and enters the lock recess 5b of the key 5 at the unlocked position. However, the key 5 cannot be pulled out from the key hole 3b, and at the same time, the locking driver pin 6a crosses the contact surface between the cord pin 8b and the driver pin 6b, so that the plug 3 cannot be rotated. To restore the vending machine, it is necessary to replace the lock device.
