2. Description of the Related Art Conventionally, in this type of vending machine,
As shown in FIGS. 13 and 14, a door body 3 provided with a bill insertion slot 2A and a coin insertion slot 2B, which are money insertion sections 2, on the front surface of a machine body 1 in which products are stored is assembled so as to be openable and closable. Banknotes or coins input from the input unit 2 are sorted by a money sorter (not shown) and stored in a safe (not shown) installed inside the door body 3.

When the door body 3 is assembled to the machine body 1 so as to be openable and closable, the lower end face 3a side at one end of the door body 3 is previously attached to the machine body 1 side by a lower hinge pin and a hinge plate (not shown). 15 and 16, the hinge pin 5 of the upper hinge plate 4 fixed to the top plate surface 1a side of the machine body 1 is inserted into the shaft hole 31 opened in the upper end surface portion 3b of the door body 3 as shown in FIGS. It is done by inserting.

Further, in the conventional door hinge structure in such a vending machine, the upper end surface portion 3 of the door body 3 is
In the door hinge portion where the shaft hole 31 and the screw holes 32, 32 are opened at one end of b, the shaft hole 61 has a thickness of 1.
A rainwater intrusion prevention plate 6 made of a 2 mm sheet metal is arranged with a gasket ring 7 made of silicon having a thickness of 1.0 mm interposed therebetween, and screw holes 62 provided in the plate 6 are provided.
The screws 8 and 8 are inserted into the screws 62, respectively, and fixed by being screwed into the screw holes 32 and 32 on the door body 3 side.

On the other hand, the hinge pin 5 of the upper hinge plate 4 has a thickness of 2.3 mm in the shaft hole 61 of the contact plate 6 corresponding to the shaft hole 31 on the door body 3 side via the gasket ring 7 (steel plate). After inserting the hinge pins 5, the upper hinge plate 4 is bolted to the nut holes 11 and 11 provided at the hinge mounting portion of the top plate surface 1a on the machine body 1 side. By fastening and fixing via 12 and 12, measures for preventing rainwater intrusion are taken.

Further, the upper hinge plate 4 is provided in the body 1
The fixed piece portion 41A fixed to the top plate surface 1a side of the above and a mounting piece portion 41B extending from the fixed piece portion 41A toward the upper end surface portion 3b side of the door body 3 are formed on the fixed piece portion 41A. , Bolt insertion hole 4 with a diameter larger than the diameter of the bolts 12, 12
The mounting piece portion 41B has a pin hole 43 into which the hinge pin 5 is press-fitted and fixed by caulking, and the height of the head 8a of each screw 8 is formed. And a height corresponding to the thickness of the washers 9 and 10 interposed between the contact plate 6 and the contact plate 6, for example, a height t of 6 mm, which is lifted and bent in a stepped state from the fixed piece 41A. Accordingly, the upper end surface portion 3b of the door body 3 and the top plate surface 1a of the machine body 1 are assembled so as to be flush with each other.

[0007]

However, in the above-described door hinge structure in the conventional vending machine, the door hinge portion formed between the upper end surface portion 3b of the door body 3 and the mounting piece portion 41B of the upper hinge plate 4 is not formed. Gap a
However, since the size is large according to the floating height t of the mounting piece 41B, when the machine body 1 is installed outdoors, the door body 3 is pryed open by inserting a burl or the like through the gap a at the door hinge portion, There is no end to mischief such as the stolen money stored in 1 and money in the safe installed inside the door body 3.

In order to prevent such mischief, a gasket ring 7 interposed between the upper end surface portion 3b of the door body 3 and the contact plate 6, and a mounting piece portion 41B of the contact plate 6 and the upper hinge plate 4 are provided. Since parts such as washers 9 and 10 which are interposed between the screws 8 and 10 are indispensable as a measure for preventing rainwater intrusion, the height of the head 8a of each screw 8 is lowered to thereby form a gap a in the door hinge portion. Can be reduced, but there is also a structural limit.

The present invention has been made in view of the above circumstances, and it is possible to reduce the gap between the door hinge portions and prevent theft of merchandise or money by opening the door. An object of the present invention is to provide a door hinge structure.

The upper end surface portion 3b of the door body 3 and the top plate surface 1a of the machine body 1 can be assembled so as to be flush with each other, while the outer peripheral edge portions 4a, 4b sandwich the pin hole 43 therebetween. Band-shaped swelled portions 44, 44 are formed by step bending on the lower surface on the side.

Each of these bulging portions 44, 44 is a head 8 of a screw 8 for fixing the contact plate 6 with a screw by opening and closing the door body 3.
It is formed so as to project outside the movement trajectory of a, and the upper end surface portion 3b of the door body 3 and the attachment piece portion 4 of the upper hinge plate 4 are formed.
The clearance a at the door hinge portion around the hinge pin 5 between 1B and 1B is maintained at an interval that prevents insertion of a burl or the like, for example, an interval of about 2 mm.

That is, in order to assemble the door body 3 on the machine body 1 side, first, the gasket ring 7 is interposed at the door hinge portion where the shaft hole 31 is opened at one end of the upper end surface portion 3b of the door body 3. The plate 6 is arranged, and the shaft hole 61 and the gasket ring 7 of the contact plate 6 are positioned so as to correspond to the shaft hole 31 and the screw holes 62.62 correspond to the screw holes 32 and 32 on the door body 3 side. After that, the screws 8 and 8 are respectively inserted into the screw holes 62.62 and the screw holes 32 and 32 to fix the screws, thereby fixing the contact plate 6 to the upper end surface portion 3b of the door body 3.

Then, the lower end portion 3a side of the door body 3 corresponding to the door hinge portion is pivotally supported on the machine body 1 side by a lower hinge pin and a hinge plate (not shown), and then the upper end surface portion 3b of the door body 3 is assembled. The hinge pin 5 provided on the mounting piece portion 41B of the upper hinge plate 4 is inserted into the shaft hole 61 of the contact plate 6 fixed to the above through the washers 9 and 10. Then, the fixing piece portion 41A of the upper hinge plate 4 is arranged at the hinge attachment portion of the top plate surface 1a on the machine body 1 side, and the fixing piece portion 41A is arranged.
After positioning the bolt insertion holes 42, 42 provided in A corresponding to the nut holes 11, 11 on the machine body 1 side, the bolt 1
It is formed by fastening and fixing at 2 and 12.

6 to 8 show a second embodiment of the upper hinge plate 4. The upper hinge plate 4 is made to project to the lower surface of the mounting piece portion 41B on the outer peripheral edge portions 4a, 4b side. The belt-shaped bulging portions 44, 44 are formed by beading.

9 to 12 show the upper hinge plate 4
The upper hinge plate 4 is a third embodiment of the present invention, and the upper hinge plate 4 is drawn in a range excluding the periphery of the pin hole 43 of the mounting piece portion 41B shown by hatching in FIG. The bulging portion 44 is formed so as to project on the lower surface of the.

It is needless to say that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0027]

As is apparent from the above description, according to the present invention, since the bulging portion is provided on the lower surface of the mounting piece portion of the upper hinge plate assembled to the upper end surface portion of the door body,
It is possible to reduce the gap between the upper end surface portion of the door body and the attachment piece of the upper hinge plate at the door hinge portion, and thus to prevent insertion of a burl or the like from the conventional gap at the door hinge portion. Therefore, it is possible to reliably prevent mischief such as theft of goods or money due to prying doors.

Moreover, since it is possible to maintain the current number of parts used for rainwater intrusion prevention measures without changing, it is possible to obtain the same rainwater intrusion prevention effect as before.
