Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a door opening / closing control device that opens and closes an entire opening of a vending machine.

[0002]

[Prior art]

 An example of such an opening / closing control device is disclosed in Japanese Utility Model Laid-Open No. 3-86478, which includes a rod having a supporting end rotatably supported by a door, and an engaging end of the rod. The vending machine is equipped with a guide body on the floor of the vending machine that guides the door when the door is opened or closed.

FIG. 2 shows the structure of a vending machine provided with such a conventional door opening / closing control device. Inside the vending machine body 1 (hereinafter referred to as the body) having a front opening, an inner door 9 is provided. There is formed a product storage 3 which is opened and closed. On the front surface of the main body 1, there is provided a front door 5 which is rotatably supported by a rotary shaft 6 so as to open and close the opening 4. The rotary shaft 6 is provided on both upper and lower sides of the main body 1. It is pivotally supported by front door hinges 6a and 6b provided on the. The base portion 5a of the front door 5 is rotatably supported by the door base hinge 7.

A rod 10 whose one end is rotatably supported by a support fitting 11 fixed to the front door 5 is arranged at the lower rear portion of the front door 5, and an engaging end of the rod 10 is arranged downward. It is bent and its tip is fitted into a guide body 11 provided on the floor surface of the main body 1, and is fixed by a washer 13 and a split pin 14 from the back side of the guide body 11 (FIG. 3).

The guide body 11 is formed with locking recesses 15a, 15b, 15c for locking the front end of the rod 10 so as to fix the front door 5 at a predetermined position, and the front end of the rod 10 is formed. When the front door 5 is opened, the engaging end of the rod 10 slides on the guide body 11 as the front door 5 rotates, and the engaging end engages with any one of the locking recesses 15a, 15b, 15c. When stopped, the front door 5 is fixed in that position.

[0006]

[Problems to be solved by the device]

 However, in the conventional door opening / closing control device, since the guide body 11 exists on the floor surface of the main body 1 as a protrusion, the flange portion of the roller provided on the bottom surface of the front door 5 when the front door 5 is closed is the guide body 11. If you hit it, it may be difficult to close it. Therefore, the present invention provides a door opening / closing control device that does not interfere with the closing of the front door.

[0007]

[Means for Solving the Problems]

 The present invention is a vending machine equipped with a door that opens and closes an entire opening formed in the main body. And a guide groove formed on the surface of the floor plate of the main body and into which the locking end is movably fitted.

[0008]

[Action]

 The locking end of the rod has a shape that expands to the peripheral portion by header processing, and the cross-sectional area of that portion is larger than the diameter of the rod. The tip of this rod is inserted from the peripheral edge into the guide groove, and one end of the rod is rotatably attached to the lower end of the back of the door with the locking end being perpendicular to the floor plate. It is locked without being pulled out from the guide groove, and the locking end of the rod can slide in the guide groove as the door rotates. Therefore, a door opening / closing control device having no protrusion on the floor surface of the main body is realized.

[0009]

【Example】

 A door opening / closing control device according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. In these figures, the same or the same parts as those in FIGS. 3 and 4 are indicated by the same drawing numbers. This invention omits the conventional guide body 11 and forms the guide groove 12 directly on the surface of the floor plate 11 of the main body 1. Then, as shown in FIG. 4, the locking end of the rod 10 has a shape that is soaked by header processing and spread to the peripheral portion, and the cross-sectional area of that portion is larger than the diameter of the rod. The tip of this rod is inserted from the peripheral edge into the guide groove 12, and the other end of the rod 10 is rotatably attached to the lower end of the rear surface of the front door 5 with the engaging end being perpendicular to the floor plate 11. By mounting, the locking end of the rod 10 is locked between the floor plate 11 and the bottom plate 18 without coming out of the guide groove 12, and the locking end of the rod 10 is locked in the guide groove 12 as the front door 5 rotates. I will move along.

A cylindrical sliding member 13 made of resin is inserted into the locking end of the rod 10, and the rod 10 is moved while the sliding member 13 slides on the inner wall of the groove 12. ing. As a result, the strain when the rod 10 moves in the groove 12 is prevented and the guide groove 12 is prevented from being deformed. Then, in the guide groove 12, when the front door 5 is opened, the locking recess 12a that locks the locking end of the rod 10 so as to fix the front door 5 at each stage as the front door 5 rotates. 12b and 12c are formed.

[0011]

[Effect of device]

 As described above, according to the present invention, there is provided a door opening / closing control device that does not interfere with the closing of the door. Moreover, because the locking end of the rod is processed into a header and the guide groove is formed directly on the floor plate, not only can the number of parts be significantly reduced compared to the conventional door opening / closing control device, but also Assembling is also improved.
