Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column door of a vertically stacked product rack for a vending machine for paper pack products.

[0002]

2. Description of the Related Art The column door of a vertically stacked product rack described above is a door for replenishing products attached to the front of a product rack case. When replenishing products, the door is opened to store the products in a rack. It also locks the doors to the closed position and prevents the products stored in the storage from falling off, and also functions to guide the products that move down in the rack during the sales operation.

Conventionally, the column door is straddled between the horizontal frames installed above and below the front surface of the rack case, and the upper and lower ends of the hinge shaft provided on the side edge of the door plate are fitted in the shaft holes of the horizontal frame. The door plate is pivotally supported so that it can be freely opened and closed, and a stopper plate is provided on the door plate as a separate component. When the column door is closed, the stopper plate is locked to the rack by locking the stopper plate to the closed position.

[0004]

By the way, the conventional column door in which the stopper is operated to lock the door to the closed position as described above has the following problems. In other words, 1) If the column door that was opened during product replenishment is forgotten to be locked when it is closed again, the column door will naturally open halfway due to vibration and shock applied during the sales operation after the restart of the sales. Therefore, there is a possibility that the products stacked and stored in the product rack may collapse.

2) Also, when the column door is half-opened and not held in a predetermined closed position during the selling operation, the door plate does not function as a guide for the product moving downward in the refrigerator, and therefore the product The storage posture may be disturbed and it may get caught in the horizontal frame of the rack, causing a trouble that it cannot be carried out. The present invention has been made in view of the above points, and an object thereof is to solve the above-mentioned problems and to simply push the door plate to the closed position when closing the column door, which requires a special clasp operation. Without automatically locking the door in the predetermined closed position,
At the same time, it is to provide a column door for a vertically stacked product rack of a vending machine that has excellent operability and functionality that also ensures a guide function for stored products.

[0006]

In order to achieve the above object, according to the present invention, a hinge shaft is provided on a side edge of a door plate, which straddles between horizontal frames which are vertically installed on one side surface of a rack case. In a column door in which the upper and lower ends of the column door are fitted into the shaft holes of the horizontal frame so that they can be opened and closed freely,
A tapered stopper part is formed that extends from the hinge side to the anti-hinge side with its edge slanting downward, and when the column door is closed, the stopper part is dropped inside the horizontal frame to close the door plate. It shall be configured to lock and hold in position.

Further, in the above construction, the upper and lower horizontal frames mounted on the product rack are angle bars having an L-shaped cross section, and the plate hole of the side projecting forward is fitted with a shaft hole for fitting the hinge shaft of the column door. Shall be perforated. In addition, the door plate of the column door has a U-shaped cross section, and a curl portion is formed on the hinge side side edge to attach the hinge shaft protruding vertically, and the lower edge part of the door plate is attached to the left and right side edges. A taper-shaped stopper portion is formed here by extending downward.

[0008]

With this structure, when the column door is pushed from the open position to the closed position, the horizontal frame erected on the lower part of the rack case and the upper surface thereof are carried in the process of the door plate rotating around the hinge shaft. The contact point with the door plate moves from the hinge side to the anti-hinge side along the inclined surface of the tapered stopper portion that is formed to project to the lower end side of the door plate, and the door plate itself moves with this movement. When it rises upwards and the stopper finally crosses over the horizontal frame and enters the inside of the refrigerator, it disengages from the horizontal frame and falls inside it, and the door plate automatically fits in the closed position. In this closed state, since the stopper portion is hooked inside the lateral frame, the column door will not unexpectedly open even if the door plate is pushed from the inside.
When the column door is opened, it can be easily opened by manually lifting the door plate a little upward and pulling it forward.

As a result, the column door can be locked and held at a predetermined closed position by a one-touch operation of simply pushing the door plate toward the closed position without using a locking part such as a clasp. Become. In addition, since the door plate covers the inner edge of the horizontal frame at the closed position, it is possible to reliably prevent transport troubles such as a product that moves downward in the storeroom due to the selling operation being caught by the edge of the horizontal frame and bridging.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. First, in FIG. 1A, 1 is a product rack, 2
3 is a column door for replenishing products, which is placed on one side of the product rack and 3 is a product that is stacked and stored in the product rack. In FIG. 1A, the product rack 1 is provided with two left and right column doors 3, where the left column door is in a closed state and the right column door is in an open state.

Here, the box-shaped rack case 1a of the product rack 1 is provided with horizontal frames 1b and 1c, which are angle bars having an L-shaped cross section, at the upper and lower ends of the front open surface thereof, and project forward of the rack. A shaft hole 1d into which a hinge shaft described later provided in the column door 3 is fitted is opened at both left and right ends of each frame side. On the other hand, the door plate of the column door 3 has a U-shaped cross section, and the curl portion 3 is provided on the hinge side edge thereof.
a is formed and protrudes above and below the door plate to form the shaft hole 1 described above.
A hinge shaft 3b that fits in d is attached. further,
On the lower edge side of the door plate, there is a tapered stopper portion 3 that is inclined downward from the hinge side toward the opposite hinge side and projects.
c is formed. Note that θ in the figure is the stopper portion 3c.
Represents the inclination angle of.

Then, the column door 3 straddles between the horizontal frames 1b and 1c provided above and below the front surface of the product rack 1, and the hinge shaft 3b is loosely fitted in the shaft hole 1d so that it can be opened and closed. ing. The vertical dimension of the column door 3 is set to be slightly shorter than the distance between the upper and lower horizontal frames 1b and 1c provided on the rack case side. With such a configuration, when the column door 3 is in the open state, as shown in FIG.
As shown in (a), the lower end surface of the door plate on the hinge side is placed and carried on the upper surface of the horizontal frame 1c. In this door open state, the taper-shaped stopper portion 3c of the door plate protrudes at a right angle with respect to the horizontal frame 1c, so that the door plate does not sway left and right, and the door can be opened even if some external force is applied. Since it does not move in the closing direction, it is convenient for product replenishment work.

On the other hand, when the column door 3 is pushed from the open position to the closed position, the inclined lower edge of the stopper portion 3c rides on the upper surface of the horizontal frame 3c as shown in FIG. As the door is pushed, the door plate itself rises upward, and finally, as shown in FIG. 2 (c), the stopper portion 3c rides over the horizontal frame 1c and falls into the inside, and the column door 3 is moved to the position shown in FIG. It fits in the closed position shown in c).
In this state, since the stopper portion 3c on the lower end side formed on the door plate of the column door 3 is fitted inside the lower horizontal frame 1c, even if force is applied to the door plate from the inside of the refrigerator, the column There is no danger that the door 3 will open. Moreover, as can be seen from FIG. 1C, since the door plate of the column door 3 covers the inner edge of the horizontal frame 1c from the inside of the store, the product 2 moving down in the store with the selling operation is the horizontal frame 1c. There is no fear of being caught on the edge and bridging, and the product 2 is smoothly guided down along the door surface of the column door 3.

When the column door 3 is opened, it is easily opened by manually raising the door plate a little upward and then pulling it toward you.

[0015]

As described above, according to the configuration of the present invention, when the column door is closed, the door is locked in a predetermined closed position by simply pushing in the door plate. Therefore, unlike conventional column doors, no special locking device such as a lock is needed, and when the door is closed, the column door opens from the forgetfulness when the door is closed and the products are stacked and stored in the warehouse. You can surely prevent problems such as accidental dropping. Moreover,
When the column door is closed, the stopper formed on the lower edge side of the door plate covers the edge of the horizontal frame provided at the bottom of the rack case from the inside of the store, so products that move downward in the store due to sales operations Transport troubles such as catching on the edge of the horizontal frame and stopping can be avoided, and the reliability of the selling operation is improved.
