JPH0454588A - Front door stopper device for automatic vending machine - Google Patents

Abstract

PURPOSE:To optionally fix the open/close angle of the front door of an automatic vending machine within a range set previously by securing the engagement between a coupling rod and a positioning groove of a guide rail while the coupling rod is moved in the direction approximate toward the guide rail. CONSTITUTION:The movement of a slider 7 is controlled with engagement secured between the positioning grooves tC1 - 5C4 of a guide rail 5 and the engagement projections 9a and 9b of the slider 7. Thus the open/close control of a front door 4 is attained with an automatic vending machine main body 3 by means of a coupling rod 8. Furthermore the rod 8 is stored along the upper or lower side of the main body 3 via the rail 5 in a closed state of the door 4. Therefore the rod 8 occupies a very small space. As a result, the door 4 is surely kept at a set opening amount on the automatic vending machine.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a front door stopper device for a vending machine.

Conventional technology The front door attached to the vending machine body via a hinge mechanism has a coin verification mechanism, cash box, product sample,
There are many pieces of equipment such as product selection buttons and product signboards, and the overall weight is heavy.

The interior of the vending machine itself has a large storage area for products for sale, and the space occupied by the stopper device that restricts the rotation of the front door during replenishment of products for sale or maintenance is also large. It's quite restricted.

A chain type stopper device can be mentioned as a common stopper device. This connects the vending machine main body and the front door with a chain of a predetermined length, and the opening angle of the front door is limited by the length of the chain.

Problems to be Solved by the Invention Although such a chain-type stopper device does not have any problems regarding the space it occupies inside the vending machine, it is dangerous because the front door may close automatically due to strong cross winds.

The present invention can be installed in a small amount of space;
Furthermore, the front door can be opened and fixed in case of crosswinds, etc.
To provide a front door stopper device capable of reliably holding the front door at a set opening degree even when installed at a vending machine.

Means for Solving the Problems The front door stopper device of the present invention includes a guide rail that is attached along the upper or lower side of the vending machine main body and has a plurality of positioning grooves formed along its longitudinal direction,
A slider that slides while being guided by the guide rail is provided, and a connecting rod is provided whose one end engages with the front door of the vending machine main body and the other end engages with the slider, and the other end side of the connecting rod is provided. is characterized in that an engaging protrusion is provided that engages with the positioning groove of the guide rail when the connecting rod is moved in a direction approaching the guide rail.

Effect: According to this configuration, the sliding movement of the slider is regulated by the engagement between the positioning groove provided on the guide rail and the engagement protrusion provided on the slider, and the rotation of the front door relative to the vending machine body is controlled by the connecting rod. It can be regulated in either direction. Furthermore, when the front door is closed, the connecting rod is accommodated along the guide rail and along the upper or lower side of the vending machine main body, so the space it occupies is small.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 5.

Figure 1 shows a state where the front door of the vending machine 1 is closed.
FIG. 2 shows the open state. Here, front door stopper devices 2 are attached to the lower sides of the vending machine main body 3 and the front door 4, respectively. A guide rail 5 having a U-shaped end face is attached to the lower side of the vending machine body 3 along the opening of the vending machine body 3, as shown in FIG. A slider 7 is engaged with this guide rail 5, as shown in detail in FIG. This slider is a coil spring 10a in which slider chips 7a and 7b are butted against each other and these two are connected in a ring shape.

10b is placed over a concave portion 7C on the outer periphery.

One end of a connecting rod 8 is engaged with a hole 7d formed in the center of the slider 7. Note that a recess 8a is formed in the connecting rod 8 on the inner peripheral surface of the hole 7d of the slider 7.

A protrusion 7e that engages with the recess 8b is formed, and when the slider 7 slides on the guide rail 5, the protrusion 7e engages with the recess 8b as shown in FIG. Positioning grooves 5° + 5C are provided at predetermined intervals on the upper surface of the guide rail 5.
215c3... are provided.

The connecting rod 8 has an engaging piece 9 on which engaging protrusions 9a and 9b are formed.
are attached by two E-rings lla and llb, and in the state shown in FIG. Not reached.

Note that the front door 4 side of the connecting rod 8 is also bent at a right angle similarly to the slider 7 side, and is rotatably engaged with the connecting rod bearing portion 6 of the front door 4.

With this configuration, the engaging protrusions 9a and 9b can be attached to any of the positioning grooves 5c of the guide rail 5.

5 C2+ 5 C3+ 5 C4... In the state shown in FIG. I can move. Open the front door 4 to an appropriate degree,
An engaging protrusion 9 is located above the positioning groove (for example, the positioning groove 5c2 in FIG. 3) located near the slider 7 at that time.
When the staff member adjusts the opening degree of the front door 4 so that a and 9b are aligned and strongly steps on the connecting rod 8 with his/her foot, the slider tip moves against the bias of the coil springs lOa and lOb, as shown in Fig. 5. 7a and 7b are opened, and the protrusion 7e goes over the protrusion between the recesses 8a and 8b of the connecting rod 8, and the protrusion 7e descends into the recess 8.
engages a. In this state, the engaging protrusions 9a, 9b engage with the positioning grooves 5C2, the slider 7 cannot slide on the guide rail 5, and the opening degree of the front door 4 is fixed.

When closing the front door 4, when the connecting rod 8, which is in the state shown in FIG. 5, is pulled up, the engaging protrusion 9a.

9b is removed from the positioning groove 5c2, the state returns to the state shown in FIG. 4, the slider 7 is in a state in which it can slide on the guide rail 5, and the front surface AI4 can be closed.

In the above embodiment, the guide rail 5 is attached along the lower side of the vending machine, and the connecting rod 8 is stepped on to move the connecting rod 8 in the direction approaching the guide rail 5. A guide rail 5 may be attached along the upper side of the vending machine main body 3.

In this case, the opening/closing operation of the front door 4 is not performed by the foot of the staff member, but by pushing it up with one hand to move the connecting rod 8 in the direction approaching the guide rail 5.

Effects of the Invention As described above, according to the present invention, a guide rail is provided along the upper or lower side of the vending machine main body and has a plurality of positioning grooves formed along its longitudinal direction, and the guide rail is guided by the guide rail. A slider that slides is provided,
A connecting rod is provided, one end of which engages with the front door of the vending machine main body, and the other end of which engages with the slider, and the other end of the connecting rod has a connecting rod that extends in the direction approaching the guide rail. By providing an engaging protrusion that engages with the positioning groove of the guide rail when it is moved, the opening/closing angle of the front door of the vending machine can be arbitrarily fixed within a preset range. It has the advantage that the opening/closing angle will not be released even if an unexpected external force is applied from the surrounding area. Furthermore, the mechanical members constituting the door stopper device need only be attached to the upper or lower sides of the vending machine and the front door, and occupy only a small space within the internal volume of the vending machine main body.
