It is formed by a frame body 6 having a bent portion 6b bent inward so as to close a part of the passage 5. Reference numeral 7 denotes a tongue piece made of an elastic body that protrudes forward from the left and right sides of the bent portion 6b and forms an upper peripheral frame and a bearing 8 that opens forward together with the bent portion 6b. A shaft 11 formed at both upper ends of the flapper 9 is fitted to the flapper 9, and the flapper 9 is suspended in a swingable manner. Reference numeral 9a denotes an anti-theft plate that prevents nail removal or the like from being inserted into the shaft 11 from an outlet described later, and the anti-theft plate 9a is attached to the flange portion 6a by a screw 9b. 12 is an outer door that closes the front of the main body cabinet 1 so as to be openable and closable, 13 is an opening at the bottom of the outer door 12, and an outlet that is swingably closed by a flapper 10. A door frame 15 for limiting the opening of the flapper 9 indicates a product. In FIG. 5 and FIG. 6, the products 15 are stored in either a cold or hot state by being sorted by type in the product storage shelves 3 stored in the product storage 2 formed by thermally insulating the inside of the main body cabinet 1.

[Problems to be solved by the invention]
By the way, the mischief of stealing goods by inserting a hand from the outlet 13 is dealt with by restricting the opening degree of the flapper 9 by the door frame 14, but the opening degree of the flapper 9 is limited. There is also a malicious mischief of removing the flapper 9 itself. This means that a rod-shaped member is inserted from the outlet 13 to remove the flapper shaft from the bearing and remove the flapper. For such mischief, it is conceivable to lengthen the anti-theft plate 9a downward or to extend the door frame 14 to the outlet 13 side. In these cases, however, the opening degree of the flapper 9 is limited. There is a problem that the smooth carry-out of 15 is hindered.
[0005]
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an inner door of a vending machine in which a flapper cannot be removed from a product passage when the outer door is closed.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the invention according to claim 1 has a heat-insulating inner door that can be opened and closed so as to be able to open and close the front of the inside of the store where the product is stored in either a cold or cold state. A rectangular frame having a flange abutting against the inner door surface is fitted into the opened square hole to form a product passage, and shafts provided at both ends of the upper part of the flapper are provided at both upper corners of the frame. It is inserted into a bearing having an opening on the front and suspended, and the flapper normally closes the product passage so that it can be pushed open by the product when the product passes through. In the vending machine regulated by the door frame projecting to a position, a protrusion is provided at a position facing the door frame of the flapper and projecting forward over substantially the entire width of the flapper.
[0007]
With the above configuration, it is difficult to remove the flapper when the outer door is closed because the protrusion of the flapper interferes with the rod-shaped member that is inserted from the outlet of the product to remove the flapper shaft from the frame. It becomes possible to prevent mischief of stealing goods in the storehouse.
[0008]
Further, as in the invention according to claim 2, in the inner door of the vending machine according to claim 1, when the flapper is in a suspended state in proximity to the axis of the flapper, a notch portion whose bottom surface faces the vertical direction is provided. And a stopper that prevents the shaft from slipping off when the flapper is in the suspended state when the flapper is placed in a horizontal state and the shaft is mounted on the bearing. It is characterized by providing.
[0009]
With the above configuration, when the flapper shaft is pushed into the bearing, the flapper is leveled so that the bottom of the notch is substantially horizontal, and the notch is passed through the stopper of the frame body and the shaft is pushed into the bearing. In the range of the opening until the product is pushed open by the product from the substantially vertical state (the position where the flapper is blocked by the door frame of the outer door and no longer opens), the bottom surface of the notch is close to the vertical angle. Therefore, the stopper can prevent the shaft from coming off from the bearing.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a cross-sectional configuration diagram of the main part of an embodiment of the present invention, and FIG. In FIG. 1 and FIG. 2, members having the same reference numerals as those of the conventional example have substantially the same functions, and therefore description thereof is omitted.
