(F) Embodiment Figures 1 to 3 show embodiments of the present invention.
1 is the vending machine itself, and there is a door 1 on the front that can be opened and closed.
2 is pivotally mounted. Reference numeral 13 denotes a key receiving member fixed to the main body 11 side, and lock portions 14 are provided at multiple locations above and below the front end. This locking portion 14 locks a locking pin 19 which will be described later, and locks the locking pin 19 that is attracted by the sloped portion 15 that is sloped so as to attract the locking pin 19 toward the main body 11 side. U-shaped locking part 1 to be fixed
6. Reference numeral 17 denotes a lock member having a substantially U-shaped cross section, and is fixed to the opening/closing end of the door 12 with a stepped bolt 18 so as to be slidable in the vertical direction.
A plurality of lock pins 19 are rotatably supported between the opposite sides in correspondence with the lock portion 14, and when the door 12 is closed, the front end of the key receiving member 13 is connected to the lock member. The lock pin 19 is interposed between both sides of the lock portion 17 so that the lock pin 19 can be engaged with the lock portion 14 . A handle base 20 is provided on the front surface of the door 2 in correspondence with the lock member 17, and rotatably supports a handle member 21 formed in a substantially dogleg shape. The handle member 21 is rotatably supported at an intermediate portion between the handle portion 22 and the actuating portion 23, and the tip of the actuating portion 23 is engaged with a connecting groove 24 provided in the lock member 17, so that the handle portion 22 becomes a handle. The lock pin 19 of the lock member 17 is configured to be locked in the locking portion 16 of the key receiving member 13 in the closed position stored in the base 20, and the upper end of the handle portion 22 is connected to the handle base. In the open position extending forward from the base 20, the lock pin 19 of the lock member 17 is configured to correspond to the opening of the lock portion 14 of the key receiving member 13.
Reference numeral 25 denotes a key device that is rotatably operated by a key, and is rotatably provided with a locking piece 27 that can be locked and detached from a locking hole 26 formed at the upper end of the handle portion 22 . 2
Reference numeral 8 denotes a spring that urges the handle portion 22 to protrude to a forward position where it can be operated while the lock pin 19 is locked to the locking portion 16.

To explain the closing/locking operation of the door 12 in the above configuration, first, the door 12 is brought into contact with the main body 11 while the handle portion 22 is extended forward of the door 12 .
At this time, the locking member 17 is slid upwardly by the actuating portion 23. Therefore, lock pin 1
9 is a state in which the lock part 14 has been entered. In this state, when the handle portion 22 is pressed and rotated in a direction to abut the door 12, that is, to be housed in the handle base 20, the actuating portion 23 slides the lock member 17 downward. Therefore, the lock pin 19 comes into contact with the inclined part 15 of the lock part 14, is guided while being rotated, is drawn toward the main body 11, and is fitted into the locking part 16 and locked therein. Due to the locking of the lock pin 19, the door 12 is brought into pressure contact with the main body 11 in a closed state. On the other hand, in this state, the handle portion 22 is housed in the handle base 20 and is in a closed state. Then, operate the key device 25 with a key (not shown), and lock the locking piece 27.
is rotated and locked into the locking hole 26 of the handle portion 22, and the handle member 21 is fixed. The operation of closing and locking the door 12 to the main body 11 in this way is
The handle part 22 is pressed against the main body 11 and the handle part 22 is pressed in the direction of the door 12 together with the door 12, and the lock pin 19 is locked to the lock part 14 while rotating, so it is easy to apply force and it can be done with a weak force. The door 12 can be closed by pressure contact very easily.

In addition, when opening the door 12, the locking piece 27 is moved into the locking hole 2 by operating the key device 25 with a key (not shown).
6, the elasticity of the spring 28 causes the handle portion 22 to protrude forward to a position where it can be operated. By pulling down the protruding handle portion 22 forward, the lock member 17 slides upward, and the lock pin 19 is removed from the lock portion 14. At this time, the lock pin 19 is rotated and removed from the lock part 14, so there is little frictional resistance and the lock can be unlocked easily.

(g) Effects of the invention As described above, the invention includes a lock member comprising a plurality of rotatable lock pins that are slidable in the vertical direction within the opening/closing side end of the door, and a lock member provided on the main body side. a lock portion provided with an inclined portion that closes the door by engaging with the lock pin and pressing the door toward the main body; and one end of the handle portion is supported so as to be rotatably extended forward from the front surface of the door; The lock member is slid so that the lock pin is removed from the lock portion by rotating the handle portion forward, and the lock pin is engaged with the lock portion by rotating the handle portion in a direction to abut the door. Since it is composed of a handle member and a key device that fixes the handle member at the position of the handle part where the lock pin is engaged with the lock part, the door can be closed by pressure contact with the main body, and it can be closed with a weak force. The door can be locked and unlocked easily and reliably.
