  By the way, when the waterproof gasket having the above-described structure is mounted on a vending machine and used, it has been found that there are the following problems in terms of waterproof performance. That is, when the outer door 2 of the vending machine is rotated around the axis 3a of the hinge fitting 3, the corner 2b that sharpens the inner edge of the outer fitting 2 side as shown in FIG. The trajectory draws a trajectory of compressing and sliding the gasket member 7b over a path of length L. The outer door 2 and the corner 2b are made of steel and are sharpened, and the opposing gasket member 7b is molded of a soft resin such as a soft elastomer. Accordingly, since the gasket member 7b is integrally formed with a soft hollow, the gasket member 7b absorbs and receives the compression force F by itself, and the gasket member 7b is rubbed and broken by repeating this operation.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a waterproof gasket for a vending machine which is improved so as to solve the above-described problem of rainwater intrusion to improve waterproofness.

  In order to achieve the above object, in the waterproof gasket of the present invention, a clip part that is fitted into the upper edge of the outer box of the cabinet from the inside and locked to a long frame that is an extruded product of hard resin, and the upper surface of the outer box A rib-shaped engagement protrusion protruding to the side is formed, and a hollow soft gasket member is formed on the front surface of the clip portion integrally with the frame, and a cut is made from the hinge fitting side end of the soft gasket member. Form and configure.

  According to the above configuration, compared to the conventional waterproof gasket, since the cut is formed from the hinge fitting side end of the soft gasket member, when the outer door is rotated around the axis of the hinge fitting, The corner portion of the outer door at the edge of the hinge bracket side sharply applies a compressive force to the soft gasket member, but the soft gasket member displaces and moves by the compressive force at the notch portion to diffuse the compressive force. This prevents the gasket member from being rubbed and broken by the corners when the outer door is rotated. Accordingly, rainwater collected on the ceiling of the cabinet can be reliably prevented from entering the inside of the vending machine through the waterproof gasket, and the waterproof performance of the waterproof gasket is improved.

  The vending machine according to the present invention prevents the soft gasket member from being rubbed and broken by the corner portion when the outer door is rotated, so that rainwater collected on the ceiling of the cabinet enters the inside of the vending machine through the waterproof gasket. Can be reliably prevented over a long period of time, thereby improving the waterproof performance and reliability of the waterproof gasket.

  According to the first aspect of the present invention, in the vending machine in which the outer door is attached to the front surface of the cabinet via the hinge bracket, the outer door is attached to the upper edge of the front door of the cabinet for storing the product in the cabinet. In the long frame that becomes a hard resin extrusion molded product, a clip part that fits and locks from the inside to the upper edge of the outer box of the cabinet, a rib-like shape that protrudes to the upper surface side of the outer box An engaging protrusion is formed, and a hollow soft gasket member is formed on the front surface of the clip portion integrally with the frame to form a cut in the soft gasket member. Gasket scraping and tearing can be reduced.

  The invention according to claim 2 is the same as the invention according to claim 1, but the notch is formed on the side end side of the hinge fitting to which the outer door is attached, and is formed on the hinge side where stress is easily applied. It is.

  The invention according to claim 3 is the invention according to claim 1 or 2, further, the notch is provided over a length exceeding the rotation locus position of the corner from the hinge metal fitting side end of the soft gasket member. It is.

  In the invention described in claim 4, in addition to the invention described in claim 1 or 2, the incision is made in a direction along the rotation locus of the corner.

  The invention as set forth in claim 5 is a gasket having a waterproof function for preventing rainwater from entering into the cabinet in addition to the invention according to any one of claims 1 to 4.

(Embodiment 1)
Hereinafter, Embodiment 1 of the present invention will be described with reference to FIGS. In addition, in the figure of this Embodiment, the same code | symbol is attached | subjected to the member corresponding to FIG. 4, and the detailed description is abbreviate | omitted.
