Description

[Detailed Description of the Invention] This invention relates to a door positioning device that is attached to an opening of a main body of a vending machine or the like.

When a vending machine is provided with a locking device in which a locking piece is provided on the free end side of the door and is rotated by a handle, and the hook of this locking piece is engaged with a locking part provided on the main body, It is necessary to precisely match the positions of the lock piece and the locking part. To do this, it is necessary to accurately adjust the position of the shaft and bearing that attaches the door to the main body, but if the door is large and heavy, the door may fall under its own weight and become misaligned. Furthermore, even if the adjustment is made accurately at first, it often goes awry due to wear on the shaft and bearings.

If the door is installed incorrectly in this manner, the lock piece attached to the free end of the door will not properly engage with the locking portion provided inside the opening of the main body.

The purpose of this invention is to solve the above problems and
Even if there is some problem with the door mounting part, the lock piece attached to the inside of the door or the opening of the main body can be fixed at the free end of the door by accurately positioning the door. An object of the present invention is to obtain a device that always correctly engages with a locking portion provided on the inside of the device.

That is, this invention fixes a separate support frame inside the opening of the main body or the inside of the door, provides a locking part on this support frame to engage with the hook of the lock piece, and also allows the roller to be moved horizontally. It is rotatably mounted on a shaft, and on the free end of the door or inside the opening of the main body, there is a lock for the locking part provided on the support frame, which comes into contact with the top and bottom of the roller when the door is closed. This invention provides a door positioning device equipped with a positioning frame having upper and lower guide pieces for determining the position of the pieces.

The details of this invention will be explained below based on an embodiment shown in the attached drawings.

In Figures 1 to 3, 1 is a main body, 2 is an opening, and 3 is a door for opening and closing this opening 2. The figure shows the free end of this door 3, and the upper and lower ends of the other end (not shown) are The main body is attached to the shaft so that it can rotate freely.

A vertically long mounting hole 4 is provided in the front surface of the free end of the door 3, and the upper end of a vertically long main handle 5 that fits into the hole 4 is rotatably mounted on a horizontal shaft 6 within the hole 4. Reference numeral 7 denotes a mounting frame fixed to the inside of the door 3, and a locking piece 8 is rotatably mounted on the upper part of the mounting frame by means of a horizontal shaft 9.

10 is a support frame fixed to the main body 1, and this frame 10
A locking part 11 made of a rotatable tube is provided at the upper part of the lock piece 8, and a hook part 12 at the upper part of the locking piece 8 engages with this locking part 11.

A secondary handle 13 is provided inside the upper part of the main handle 5.
is mounted so that it can rotate within a certain range using a shaft 6. This secondary handle 13 and the lock piece 8 are connected by a link 14, and the secondary handle 13 is connected to the shaft 6.
A spring is provided to rotate the lock piece 8 rearward about the lock piece 8, and a spring is provided to rotate the lock piece 8 downward.

Reference numeral 15 in FIG. 1 is an engaging member that is attached to the lower end of the main handle 5 so as to be able to rise and fall and is pressed down by a spring. Prevents rotation.

Reference numeral 17 denotes a mounting tube fixed to the door 3 below the mounting hole 4. A key shaft 18 rotated by a key is attached to this tube 17, and a cam 19 is fixed to the inner end thereof. Reference numeral 20 denotes a swinging piece attached to the lower end of the mounting frame 7, whose front end touches the lower end of the engaging member 15, and whose lower side is pressed against the cam 19 by a spring.

Reference numeral 21 denotes a roller attachment portion protruding from the lower front end of the support frame 10, and a roller 22 is rotatably attached to this attachment portion 21 about a horizontal shaft.

23 is a positioning frame fixed to the mounting frame 7;
Guide pieces 24, 25 are provided above and below, and the rear ends of both guide pieces 24, 25 are opened up and down as shown in FIG. 1, so that the roller 22 can easily enter between the guide pieces 24, 25.

The device of this invention has the above-mentioned configuration, and each figure shows a state in which the opening 2 is closed with the door 3. At this time, the roller 22 is inserted between the upper and lower guide pieces 24, 25, so the door 3 is in the correct position. is held by the lock piece 8.
The hook portion 12 engages with the locking portion 11 to lock the door 3.

To open the door 3 from this state, turn the key shaft 18 with the key, push up the swinging piece 20 with the cam 19, the swinging piece 20 pushes up the engagement member 15 and removes it from the locking piece 16, and the main handle is activated by the spring. 5 first
The position is indicated by chain line a in the figure. Next, when the main handle 5 is turned to the position indicated by the chain line b in FIG. 1, the lock piece 8 rotates and the hook portion 12 is disengaged from the locking portion 11, so that the door 3 can be opened.

When the door 3 opened by the above operation is closed, the upper and lower guide pieces 24 and 25 come into contact with the upper and lower parts of the roller 22 to position the door 3 vertically, so when the main handle 5 is operated, the lock piece 8 is As shown in the diagram, the hook part 1
1 to lock the door 3.

As mentioned above, a roller is attached to the main body of a vending machine, etc., and upper and lower guide pieces are provided on the door to determine the upper and lower positions of the door by contacting the upper and lower parts of this roller, so that the door can be positioned accurately when closing. However, in the case of this invention, a separate support frame is fixed inside the opening of the main body, and a locking part that engages with the hook of the lock piece provided on the door is attached to this support frame. A major feature is that the roller is rotatably mounted on a horizontal axis.

In other words, if the locking part and roller are installed separately inside the opening of the main body, it is necessary to adjust the installation position of the roller so that it fits correctly between the upper and lower guide pieces of the door positioning frame, and to make sure that the roller is It is necessary to adjust the position of the engaging part so that the hook part of the door lock piece will properly engage with the engaging part when the door is properly inserted between the guide pieces.

However, in the case of this invention, the roller and the locking part are attached to a support frame separate from the main body, so just by correctly installing this support frame inside the opening of the main body, the roller and the locking part can be attached. Since they are positioned naturally, there are advantages such as extremely easy assembly and adjustment.

In the embodiment, the roller is attached to the main body and the positioning frame is attached to the door, but it goes without saying that the reverse may be used.
