BACKGROUND OF THE INVENTION
The present invention relates to a security cover device for a vending machine that covers a money storage part in order to prevent the theft of money stored in a money storage part of a vending machine.
[0002]
[Prior art]
Conventionally, what is shown in FIGS. 6-8 is known as this kind of crime prevention cover apparatus. The security cover device 50 is provided so as to cover the banknote handling device 56 attached to the main door 55 of the vending machine 54, and is a vertical projecting rearward along the banknote handling device 56 from the back of the main door 55. A support plate 51 and an opening / closing cover 52 rotatably attached to the support plate 51. The opening / closing cover 52 has a box shape that can substantially cover the latter half of the banknote handling device 56, and the back side portion of the banknote handling device 56 from which the stored banknotes are taken out is the support plate 51 and the opening / closing cover 52. Almost covered by. Thus, for example, a bar or the like is inserted into the seam 55a of the main door 55 located on the left side of the banknote handling device 56, and the seam 55a is forcibly expanded to a size where a hand can be inserted. If you try to take it out, this will be prevented.
[0003]
Further, as shown in FIG. 7, the connecting portion of the opening / closing cover 52 and the support plate 51 constitutes a hinge 53, and the rotation axis 53a of the hinge 53 is concretely tilted with respect to the vertical direction. Is configured to tilt slightly upward and obliquely to the right when viewed from the front. At the time of maintenance, when taking out the banknote from the banknote handling device 56, after opening the main door 55, the opening / closing cover 52 is rotated counterclockwise by hand to the open position indicated by the two-dot chain line, The bill is taken out by opening the back side of the handling device 56. Thereafter, when the opening / closing cover 52 is released, the opening / closing cover 52 is rotated by its own weight to the closed position shown by the solid line in FIG. 7 due to the eccentricity of the rotation axis 53a of the hinge 53. In this way, by tilting the rotation axis 53a of the hinge 53, forgetting to close the open / close cover 52 is prevented. As a result, damage to parts in the vending machine when the main door 55 is closed with the opening / closing cover 52 forgotten to be closed is prevented, and illegal removal of banknotes is prevented.
[0004]
[Problems to be solved by the invention]
According to the conventional crime prevention cover device 50 described above, in order to prevent the opening / closing cover 52 from being forgotten to be closed, the ends of the opening / closing cover 52 and the support plate 51 on the connecting portion side are respectively rotated by the hinges 53 constituted by them. It must be formed so that the axis 53a is inclined. For this reason, when the opening / closing cover 52 and the support plate 51 are manufactured, compared to the case where the rotation axis 53a is configured vertically, the part structure becomes complicated, which makes processing difficult and increases the manufacturing cost. I will. In addition, the hinge 53 itself becomes wider due to the inclination of the rotation shaft 53a, and the rotation space of the opening / closing cover 52 becomes larger, so that a large installation space is required in the vending machine 54.
[0005]
The present invention has been made in order to solve the above-described problems. A security cover device for a vending machine that can reliably prevent forgetting to close, can be manufactured relatively easily with a relatively simple structure, and can reduce installation space. The purpose is to provide.
[0006]
[Means for Solving the Problems]

A device having a first hinge portion provided on the back surface of the front wall and a second hinge portion coupled to the first hinge portion, the first hinge portion being interposed through the second hinge portion. A cover member that is rotatable about a vertical rotation axis and movable in the rotation axis direction between a closed position that covers the money storage unit and an open position that opens the money storage unit, and the cover member An abutting portion that abuts from above, and one of the cover member and the abutting portion is formed with an inclined surface that guides the cover member upward as the cover member rotates to the open position side. When the cover member is in the open position, it abuts at a position in the middle of the inclined surface. Characterized in that it is configured to abut the.
[0007]
According to the security cover device of this vending machine, when the cover member in the closed position is rotated to the open position side by hand, for example, during maintenance, the cover member is inclined on one of the cover member and the contact portion. By being guided by the surface, it reaches the open position while moving upward. In this open position, the cover member is in contact with the contact portion at a position in the middle of the inclined surface, and its potential energy is higher than that in the closed position. Therefore, when the hand is released at the open position, the potential energy of the cover member is converted into kinetic energy, and the cover member rotates to the closed position while sliding downward on the inclined surface of the contact portion. As described above, the relatively simple structure of the inclined surface can reliably prevent the cover member from being forgotten to be closed, and the cover member is always in the closed position to cover the money storage portion, Theft of money is reliably prevented. Further, since the first hinge part and the second hinge part are pivotally connected around a vertical rotation axis, the first hinge part and the second hinge part are compared with those in which the conventional rotation axis is inclined. The hinge part comprised by the 2nd hinge part can be arrange | positioned efficiently, and the rotation space of a cover member can be reduced. Thereby, the installation space can be reduced.
[0008]
In the above, it is preferable that the contact portion is formed integrally with one of the first hinge portion and the cover member.
[0009]
According to the security cover device of this vending machine, since the contact portion is formed integrally with one of the first hinge portion and the cover member, the overall size of the device can be reduced and the contact portion needs to be manufactured separately. By eliminating this, the number of parts can be reduced.

Three cylindrical knuckles 12d, 12d, and 12d are formed at the left end of the hinge portion 12c. These knuckles 12d have the same height and are arranged in the vertical direction at a predetermined interval. . Furthermore, the height of the knuckle 12d is shorter than the interval between the knuckles 11a and 11a of the hinge member 11. Further, the knuckle 11a and the knuckle 12d form a hinge by fitting a hinge pin 13 (see FIG. 3) into each hole, respectively. The hinge pin 13, that is, the rotation axis of the hinge, has a vertical direction. It extends to. With the above configuration, the crime prevention cover 12 is attached to the hinge member 11 so as to be rotatable between an open position indicated by a solid line in FIG. 2 and a closed position indicated by a two-dot chain line in FIG. Further, it is attached movably upward by a predetermined distance d (= interval between knuckles 11a and 11a−height of knuckles 12d).
[0015]
The lower edge portion of the lowest knuckle 12d is indicated by a two-dot chain line in FIG. 5B on the inclined surface 11c of the engaging projection 11b as the security cover 12 rotates from the closed position to the open position. It slides from the position to the position indicated by the solid line in FIG.
