り、操作が煩雑である。2. Description of the Related Art Since a door of a product outlet of a vending machine is mounted on a fixed frame by a horizontal pivot, after the door is lifted and rotated, when the hand is released from the door, the rotation motor due to the weight of the door itself is rotated. The door quickly closes and rotates due to the item, and the product to be removed is caught on the door. In order to avoid such a situation, it is necessary to insert the other hand into the product outlet while holding the door in the open position with one hand. In such a case, it is necessary to temporarily put the luggage on the road or the like, and the operation is complicated.

とがある。[0003] In a vending machine which is often installed outdoors, it is necessary to prevent rain and dust from entering the product outlet from sanitary requirements, but the closing bias is limited only by the weight of the door itself. In such a method, the door may be opened unintentionally by the wind, and dust may enter the door.

It is an object of the present invention to provide a door closing biasing device capable of holding the door hermetically, since the maximum number of the door closing members can be obtained.

ｂを前側縁部１２の先端部に設ける。The door closing biasing device according to the present invention will now be described with reference to the reference numerals in the accompanying drawings. A fixed frame 3 having a door 2 that opens and closes and rotates about a hinge shaft 1 is provided. A base plate 4 is fixed to the base plate 4, and a roller 5 is mounted on a back portion of a side edge of the base plate 4 near the hinge shaft 1 by a support shaft 6 parallel to the hinge shaft 1. 1, a spring receiving portion 7 is provided at the front of the side edge of the base plate 4 farther from the hinge shaft 1 and the base plate 4.
The base end of the first link plate 8 is attached to the door 2 by a first pivot 9 parallel to the hinge shaft 1. The base end of the second link plate 10 is connected to the distal end of the first link 8 by a second pivot 11 parallel to the hinge shaft 1, and the front edge 12 of the second link plate 10 is the peripheral surface of the roller 5. The tension coil spring 15 is stretched between the spring receiving portion 14 at the end of the second link plate 10 and the spring receiving portion 7 of the base plate 4. The first bent portion 12a engaging with the roller 5;
Is provided at the base end of the front edge 12 of the second link 10 and the door 2

0 designates the roller 5 as a fulcrum, the spring receiving portion 14 as a load point,
It functions as a lever with the second pivot 11 as the point of action. When the door 2 is in the closed position as shown in FIG.
Since the front edge 12 of the link plate 10 is engaged with the roller 5 at the first bent portion 12a from the base end, the length between the roller 5 and the spring receiving portion 14 is reduced. 5 and the second pivot 11 is much longer, and the rotational moment by the force of the extension coil spring 15 is larger. for that reason,
The door 2 is strongly attracted to the fixed frame 3 side via the first link 8, and the door 2 is held in a sealed state.

する。When the door 2 is opened and rotated about the hinge shaft 1, the engagement point between the front edge 12 of the second link 10 and the roller 5 moves sequentially from the tip to the end, as shown in FIG. As shown, when the door 2 is fully opened to a predetermined angle, the roller 5
Engages with the second bent portion 12b on the tip end side. When the door 2 is in the open position as described above, the roller 5 and the spring receiving portion 1
4 is much shorter than the length between the roller 5 and the second pivot 11, so that the rotational moment due to the force of the extension coil spring 15 is small. Therefore, when the hand is released from the door 2, the door 2 rotates in the closing direction at a gentle speed.

The support shaft 6 of the roller 5 has a bearing base 17 welded to the base plate 4.
A bearing member is interposed between the support shaft 6 and the roller 5 in order to reduce rotational resistance. A bracket member 16 is fixed to the door 2 by a fixing member 20 such as a screw, and the first link 8 is pivotally connected to the bracket member 16.

ともない。In the door closing biasing device of the present invention configured as described above, the rotational moment when the door is in the open position is minimized, and the door is slowly closed at the initial stage of closing. Therefore, for example, when the present invention is applied to a door of a product take-out opening of a vending machine, it is possible to take out a product with a sufficient time margin without holding it in an open position with one hand. In addition, the complexity of the operation is eliminated. In addition, when the door reaches the closed position, the rotation moment is maximized, so that the door can be reliably held in a sealed state so that rain and dust do not enter, and the door is not driven by the wind. It does not open intentionally.
