[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a support device for an outer door of a vending machine that prevents the outer door from tilting toward the non-hinge side.
[0002]
[Prior art]
2A is an external view of the vending machine, FIG. 2B is a cross-sectional view of the vending machine, and FIG. 3 is a configuration diagram of a conventional support bracket. In FIG. 2, 1 is a main body cabinet for housing the components of the vending machine, 1a is a base that forms the bottom wall of the main body cabinet 1, 1b is a square hole drilled in the base 1a, and 1c is a base 1a. Perforated screw holes, 2 is an outer door, 3 is an inner door, 4 is a product storage shelf, 5 is a cooling unit that cools and circulates refrigerant when storing the product, 6 is a product outlet, and 7 is a product input An opening 8 is a roller attached to the lower part of the outer door 2 on the non-hinge side, and 9 is a support fitting for the roller 8. The vending machine configured as described above represents a vending machine for canned beverages, and a cylindrical can (hereinafter referred to as a product) filled with a beverage is introduced from the product inlet 7 at the top of the main body cabinet 1 into the product storage shelf 4. Stored and stored. In the room in which the product storage shelf 4 provided for each different product is stored, the main body cabinet 1 is partitioned into several rooms with a heat insulating material, and an inner door 3 formed with a heat insulating material is arranged on the front surface to form a cold and warm storage room. In order to cool the room, the refrigerant circulated from the cooling unit 5 is used for cooling. When the room is used for hot room, hot air from the heater is circulated. The goods are cooled or heated in those rooms and stored, and are discharged to the goods outlet 7 at the time of sale. Here, although not shown in the figure, the outer door 2 is a heavy article provided with a product sample display room, a money processing device for managing deposits and withdrawals at the time of sale, and other control devices. For this reason, simply attaching the hinge to the main body cabinet 1 cannot prevent the so-called door lowering in which the outer door 2 is tilted down to the anti-hinge side. Therefore, a roller 8 is attached to the lower part of the outer door 2 and the roller 8 is received by a support metal fitting 9 attached to an overhanging portion of the base 1a of the main body cabinet 1 to prevent the outer door 2 from tilting to the anti-hinge side.
[0003]
As shown in detail in FIG. 3, the support metal fitting 9 includes a downward L-bending portion 9 c at the front end, a screw insertion hole 9 d at the rear end portion, an upwardly inclined surface directed rearward at the middle portion, and a horizontal plane that follows it. A lamp way 9a is provided, and an L bent portion 9c at the front end is inserted into a square hole (locking hole) 1b drilled in the base 1a, and then a tapping screw 9e is passed through the insertion hole 9d at the rear end. The screw hole 1c is screwed.
[0004]
In this configuration, in the process of closing the outer door 2, the roller 6 is first guided on the slope surface of the ramp way 9a and gradually lifted by the slope surface, and is supported on the horizontal surface of the ramp way 9a. It will be corrected.
[0005]
[Problems to be solved by the invention]
By the way, in the conventional configuration, the mounting of the support bracket to the base is screwed, which takes time for assembly.
The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a support device for an outer door of a vending machine that eliminates screwing.
[0006]
[Means for Solving the Problems]
According to the first aspect of the present invention, a roller rotatably supported is provided at a lower part of the outer door hinged to the main body cabinet on the side opposite to the hinge, and the roller is guided rearward to the intermediate portion so as to guide or support the roller. A lampway composed of an ascending slope and a horizontal plane following it is provided with a support fitting having a bent portion facing downward at the front end and an L bent portion with the horizontal portion extending in the direction opposite to the intermediate portion at the rear end. A support device for an outer door of a vending machine, wherein a locking hole for inserting the bent portion and the L bent portion of the metal fitting is provided in the base of the main body cabinet.
[0007]
With the above configuration, the support bracket can be attached simply by inserting the front and rear bent portions into the base body. Further, the rear end of the support fitting when the roller rides on the ramp surface of the rampway is prevented.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram showing the main part of an embodiment of the present invention. In FIG. 1, members denoted by the same reference numerals as those in the conventional example have approximately the same functions, and thus description thereof is omitted. The vending machine to which the present invention is applied is the same as FIG. 2 and FIG. 3 described in the section of the prior art, so that the description thereof is omitted. In FIG. 1, 1a is a base forming the bottom wall of the main body cabinet 1, 1b is a square hole as a locking hole drilled in the base 1a, 90 is a roller support fitting attached to the lower surface of the outer door, 90a is a rampway formed in the middle part of the support metal fitting 90, which is composed of an upwardly inclined surface facing backward and a horizontal surface that follows, and 90b is an L in which the horizontal portion at the rear end of the support metal fitting 90 extends in the opposite direction to the intermediate part. A bent portion 90 c is a downward bent portion formed at the front end of the support metal 90. In FIG. 1, a support metal fitting 90 has a rampway 90a composed of an upwardly inclined surface facing backward and a horizontal surface in the middle portion, a downward bent portion 90c at the front end, and a horizontal portion facing away from the middle portion at the rear end. L-bending portion 90b extending to the base 1a is attached to the base 1a without screwing by inserting the bent portions 90b and 90c at the front and rear ends into a square hole 1b as a locking hole drilled in the base 1a. It is done. When the outer door 2 (see FIG. 2) is closed, the roller 8 attached to the lower surface of the outer door 2 on the side opposite to the hinge rides the horizontal surface of the lampway 90a of the support metal 90 and applies a downward load to the support metal 90. Therefore, the mounting of the support metal fitting 90 will not come off.
[0010]
In addition, by providing the L-bending portion 90b at the rear end of the support bracket 90, the rear end of the support bracket 90 is unexpectedly detected when the roller rides on the slope surface at the front end of the ramp way 90a in the process of closing the outer door 2. It doesn't jump off and come off.
[0011]
【The invention's effect】
According to the present invention, a tool is not required for mounting the support metal fitting, and a screw is not required, so that the number of parts is reduced and the mounting man-hour is reduced. Further, when the roller rides on the front end of the lampway, the L bent portion at the rear end of the support bracket is caught by the locking hole edge of the base, and the rear end is prevented from being lifted up.
