Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention This invention relates to a structure for opening and closing a middle door of a vending machine.

2. Description of the Related Art FIGS. 4 to 7 show a conventional middle door locking structure of a vending machine. In the figure, 1 is a door.

2 is a cabinet. 3 is a middle door. 4 is a rear door on the cabinet side (hereinafter referred to as a rear door). Reference numeral 5 is a hinge of the rear door. The rear door 4 is pivotally supported by the rear door hinge to rotate. The rear door 4 is a heat insulating wall that closes the front surface of the column 1 ′ housed in the cabinet 2. A latch 6 latches the door 1 and the middle door 3 and extends from the side surface of the door 1 to the side surface of the middle door 3 and is engaged therewith. 7
Is a leaf spring that gives a bias so that the latch 6 does not come off when the middle door 3 is hooked. Reference numeral 8 denotes a screw for fixing the latch 6 and the leaf spring 7 to each other, which is screwed to the door 1. Reference numeral 9 is a door hinge attached to the door 1, and the middle door 3 is pivotally supported by the door hinge 9 to rotate. Reference numeral 10 is a hinge provided on the cabinet 2, and the door 1 is pivotally supported by the hinge 10 to rotate. Reference numeral 11 denotes a rear door handle which is used to rotate the rear door.

The operation of the middle door structure configured as described above will be described below.

First, since the door 1 and the middle door 3 are latched by the latch 6, when the door 1 is opened, the middle door 3 naturally comes out at the same time as the door 1. When the middle door 3 is opened from the door 1, the latch 6 is removed from the middle door 3 by giving a force to the latch 6 to overcome the force of the leaf spring 7.

Problems to be Solved by the Invention However, in the above configuration, as shown in FIG. 7, the dimension A from the hinge 10 to the inner surface of the cabinet 2 is from the hinge 9 to the dimension B from the hinge 9 to the hinge 10. It is difficult to make the width larger than the width C of the door 3 added. This is because the dimension B is inevitably determined by the thickness of the door 1, and the dimension C needs to be larger than the width dimension of the storage column inside the cabinet 2. In addition, the dimension A has a condition that the dimension A must be as small as possible in order to increase the storage efficiency of the contents products, that is, the width dimension of the cabinet 2 needs to be as small as possible. Therefore, the rear door 4 is moved to the rear door handle 11
If you forget to hang the latch 6 on the middle door 3 after closing it with, and then try to open the door 1 next time,
There is a problem that the middle door 3 hits the inner surface of the cabinet 2 and the door 1 cannot be opened.

In view of the above problems, the present invention provides a middle door locking structure for a vending machine in which the latch is automatically engaged even if the door is closed without the latch being engaged with the middle door.

Means for Solving the Problems In order to solve the above problems, the middle door locking structure of the vending machine according to the present invention has a rear door, a middle door, and a rear door when the middle door is closed. The door handle is provided after pressing.

The present invention allows the rear door handle to press the middle door by closing the door, and even if the latch is disengaged from the middle door, the middle door is automatically urged to latch the latch. It is possible.

Embodiments A middle door locking structure for a vending machine according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall perspective view of a middle door locking structure of a vending machine according to an embodiment of the present invention.

In the figure, 21 is a door. 22 is a cabinet. Reference numeral 23 is a middle door that closes the opening of the door 21 and has products to be developed and the like attached. 24 is a rear door. Reference numeral 25 is a hinge of the rear door attached to the inner wall surface of the cabinet 22. Reference numeral 26 is a latch for locking the door 21 and the middle door 23. 27 is a latch 26
Is a leaf spring that gives a bias so as not to come off when the middle door 23 is hooked. Reference numeral 28 denotes a screw that engages the latch 26 and the leaf spring 27, and is screwed to the door 21.

29 is a door hinge attached to the door 21, which is a middle door
23 is pivotally supported by this hinge and rotates. Reference numeral 30 is a hinge attached to the cabinet 22, and the door 21 is pivotally supported by this hinge to rotate. Reference numeral 31 is a handle attached to the front surface of the rear door 24, that is, the side opposite to the center door, that is, the handle that is originally used to open and close the rear door 24. After that, the door handle 31 is used when the door 21 is closed.
The rear surface 23, that is, the surface facing the rear door 24, is formed with a height sufficient to contact and press. 32 is a screw that fixes the rear door handle 31 to the rear door.

The operation of the middle door locking structure of the vending machine configured as described above will be described below with reference to FIGS. 1 to 3. Door 21 with latch 26 not latching middle door 23
When the door is closed, the rear door 24 stops with the front surface of the column closed, and the rear door handle 31 provided on the front surface of the rear door 24
Is in contact with the rear surface of the middle door 23. When the door 21 is further closed from this state, the middle door 23 is pressed by the rear door handle 31, and as shown in FIG.
The end face 23b on the side opposite to the pivot 23 pushes the leaf spring 27 for urging the latch 26 wide against the elastic force. Finally, as shown in FIG. 2, the middle door 23 closes the rear opening of the door 21 and stops, and at this time, the latch 26 is supported by the elastic force of the leaf spring 27 so as to support the middle door 23. It engages with the side end surface 23b and hooks the middle door 23.

As described above, according to this embodiment, the rear door handle allows the middle door to be pressed by the rear door handle when the door is closed, so that the latch can be latched to the middle door.

As described above, according to the present invention, by providing the rear door handle that comes into contact with the middle door, even if the door is closed without locking the latch, the latch automatically opens the middle door. Since it is locked, the problem that it is difficult to open unless the middle door is caught in the cabinet when opening the door is released. Further, since the handle of the rear door is a part that presses the middle door, it is not necessary to install a new part, so that the number of parts and the number of mounting steps can be reduced.
