Problems solved by technology

That is, since the L-shaped leg portion 7c is to be formed on the hinge plate 7 made of a thicker steel plate, a sheet metal bending process is required, so the processing cost increases, and the bolts for connecting the leg portion 7c to the main cabinet are required. 11, so the number of assembly parts also increases
In addition, if the sheet metal bending accuracy of the leg portion 7c varies, when the hinge plate 7 is bolted to the main body cabinet, the plate surfaces of the leg portion 7c and the side wall reinforcement plate 10 cannot be overlapped correctly, so it is necessary to perform a The assembly process becomes complicated due to the adjustment work such as clamping the gasket between the leg portion 7c and the side wall reinforcement plate 10

Embodiment 1

[0048] First, in Figure 1 to Figure 5 shows the structure of the outer door hinge device corresponding to the first and second aspects of the present invention. The hinge device 6 of this embodiment and Figure 9 The shown conventional hinge device is basically the same, but the shape of the hinge plate 7 and the installation structure attached to the main cabinet are changed as follows.

[0049] That is, the hinge plate 7 of the illustrated embodiment is not formed Figure 9Instead of the leg portion 7c of the conventional structure, a convex engaging protrusion 7d protruding toward the side wall of the outer box 1 of the main body cabinet is formed on the side edge of the plate.

[0050] The engagement protrusion 7d is set so that the protruding height and lateral width are laid on the outer box at a predetermined installation position of the roof reinforcement plate 9 of the outer box 1 that connects the hinge plate 7 to the outer box 1 of the main cabinet with bolts 11....

Embodiment 2

[0055] Next, at Image 6 , Figure 7 The assembly structure of Example 2 of the third aspect of the present invention is shown in . That is, in the first embodiment described above, the convex engaging protrusion 7d formed on the side edge of the hinge plate 7 is inserted into the concave portion 14 of the side wall reinforcing plate 10 having a U-shaped cross-sectional corrugated structure, and is engaged and supported to be engaged with it. In contrast, in this embodiment, the positions of the engaging protrusions 7d protruding from the side edges of the hinge plate 7 are slightly shifted toward the rear side, and in this assembled position, the engaging protrusions 7d are inserted through and arranged in a corrugated position. The slit-shaped engagement groove 10a on the top surface of the protrusion of the side wall reinforcing plate 10 of the structure (refer to Figure 7 ) for engagement and retention.

[0056] With this assembled structure, the above-mentioned engage...

Abstract

The invention provides an improved outer door hinge device of vending machine. The outer door hinge device of the vending machine comprises a hinge plate (7) and a hinge pin (8), wherein the hinge plate (7) is used for protruding a hinge pin support part (7b) forwards from an outer box (1) of a main body cabinet and being connected with the inner side of a top plate of the outer box (1) through a bolt (11); the hinge pin (8) is fixedly connected with the corner on the pivot side of an outer door (2) and is rotatably supported on the hinge pin support part (7b) of the hinge plate (7); a buckling projection (7d) which is protruded towards the side wall of the outer box (1) is formed on the side edge of the hinge plate (7); at the mounting position of the hinge plate (7), the buckling projection (7d) is buckled and supported on a reinforcing plate which is paved on the inner surface of the side wall of the outer box and is corrugated; and specifically, the convex buckling projection (7d) is inserted into a concave part of the side wall reinforcing plate (10) and is locked at the position, so that the phenomena of swinging of the hinge plate and loosening and dropping of the connecting bolt caused by repeated opening / closing actions of the outer door (2) are avoided.

Description

technical field [0001] The present invention relates to a hinge device for supporting a single-opening outer door on a main body cabinet of an automatic vending machine in an openable and closable manner. Background technique [0002] As is well known, the front of the main cabinet of an automatic vending machine equipped with a product storage rack in the storage room is equipped with a single-opening outer door, and the pivot side of the outer door is pivotally connected to the main cabinet in an openable and closable manner via a hinge device. Front section. [0003] On the other hand, with regard to the hinge device of the outer door, the same applicant of the present invention has proposed that the hinge device be arranged inside the outer box of the main cabinet without exposing the outside of the cabinet in order to improve the appearance and anti-theft properties of the main cabinet. constitution (refer to patent document 1), Figure 8 , Figure 9 Indicates its ass...
