Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention relates to a door device including a pair of door bodies.

(Prior art) Fig. 1 shows the prior art, in which a and b are the first and second door bodies provided in parallel on the same plane,
These door bodies a and b have one side edge supporting shafts c and d, respectively.
It is rotatably supported via. A packing e is provided on the periphery of the second door body b, and the side edge of the first door body a on the pivot side is crimped to this packing e, thereby sealing the gap between the two door bodies a and b. , to prevent the intrusion of rainwater, dust, etc.

(Problem to be solved by the invention) However, when opening, first the first door body a is rotated in the direction of the arrow with the support shaft c as the fulcrum, and then the second door body b is rotated with the support shaft d as the fulcrum. However, even when the first door body a is open,
This first door body (a) is still pressed against the packing (e), and the second door body (b) cannot be smoothly opened due to the resistance caused by the friction.

This idea was developed with this in mind, and the purpose is that when the first door is opened, the pressure on the packing is released, allowing the second door to open smoothly. To provide a door device that can be opened.

[Structure of the invention] (Means for solving the problem) In order to solve the above-mentioned problems, this invention has a main body in the form of a casing with an open front, and the inside of the main body is inserted into the main body from the front. A pair of storage chambers partitioned so that they are parallel to each other when viewed from the left and right,
Each opening of the pair of storage chambers is provided with a pair of door bodies arranged in parallel on the left and right, and one of the door bodies disposed near one end in the left and right direction of the front surface of the housing is The other door body is rotatably supported on one side edge of a portion corresponding to the one end side edge, has packing on the periphery, and is disposed closer to the other end side in the left-right direction of the front surface of the housing. , one side edge opposite to the other side edge of the one door body is crimped to the packing, and is rotatably supported at a portion displaced from the one side edge to the intermediate side of the other door body. It is characterized by the presence of

(Function) By rotating the first door body 10 about the support shaft 20 in the direction of the arrow in FIG. 3, the front surface of the first storage chamber 4 can be opened. At this time, since the support shaft 20 is deviated only from one side edge of the first door body 10, the one side edge is separated from the packing 14 as the first door body 10 rotates, and the packing 14 The pressure bond against is released.

After opening the first door body 10 in this manner, the second door body 11 is rotated in the direction of the arrow about the support shaft 15. This opens the front surface of the second storage chamber 5. As mentioned above, the first door body 10 is removed from the packing 14 and its pressure bond is released, so that the opening operation of the second door body 11 can be performed smoothly without any resistance. I can do it.

(Example) Hereinafter, a description will be given based on an example in which this invention is applied to a door portion of a vending machine. In the figure, reference numeral 1 denotes the main body of the vending machine, which is formed into a box shape with an open front. Inside the main body 1, although not shown, there are storage shelves for items for sale, an article ejecting mechanism for ejecting the items one by one, etc. It is provided. A main door 2, which constitutes the main body of the door device of this invention, is rotatably attached to the front opening of the main body 1 via hinges 6, 6. Almost the upper half of the main door 2 is formed into a flat housing with an open front, and inside this part there are first and second storage chambers 4 and 5 arranged side by side on the left and right by a partition plate 3. It is configured. The first storage chamber 4 includes a control mechanism 8 that electrically controls the article discharging mechanism according to the insertion of coins, and the second storage chamber 5 includes samples 9 of articles for sale, etc. Each room is equipped with a storage space for lights, etc. and these first and second
First and second door bodies 10 and 11 are provided in parallel at the front open portions of the storage chambers 4 and 5.

The second door body 11 is formed by mounting a transparent panel 13 on the inside of a frame 12 to allow the above-mentioned samples 9 to be seen through, and attaching packing 14 to the outer periphery of the frame 12. One side edge of the second door body 11 is rotatably supported via a support shaft 15,
Further, a locking piece 16 is attached to the free end side of the frame 12 so as to be located inside the frame 12. A well-known locking device 17 is provided on the partition wall 3 facing the first storage chamber 4.
is provided, and this locking tool 17 allows the locking piece 1 to be
6 is removably locked.

The first door body 10 is rotatably supported via a support shaft 20 provided on its inner surface, and the side surface of one side is elastically crimped to the packing 14 of the second door body 11, As a result, the first door body 10 and the second door body 1
1 is sealed. The support shaft 20 is provided at a position that is offset from one side edge of the first door body 10 only to the intermediate side thereof.
A rotary lock 25 is provided on the free end side of the first door body 10, and a locking piece 26 of this rotary lock 25 engages with a locking piece 27 attached to the inner wall surface of the first storage chamber 4. are doing. Then, by inserting the key piece a into the rotary lock 25 from the front side of the door body 10 and rotating it,
The locking piece 26 rotates together with the engagement receiving piece 27.
They are starting to move away from it. The above locking piece 2
A packing 28 is provided on the front surface of the door 7, and the side edge of the first door body 10 on the free end side elastically abuts on this packing 28.

30 is a well-known door lock mechanism;
0 has a locking piece 31 and a release lever 32 that interlocks the locking piece 31, and the locking piece 31 engages with a locking hole 33 formed on the inner surface of the main body 1, and the release lever 32
By operating the main door 2 in the first storage chamber 4, the engagement can be released, and by releasing the engagement, the main door 2 can be opened.

In FIG. 2, 34 is a coin slot, 35 is a change return slot, and 36 is a takeout slot for selling items.

Next, the effect will be explained. First, rotary lock 25
Insert the key piece a into the locking piece 26 and rotate it to release the engagement of the locking piece 26. Then, the first door body 10 is attached to the support shaft 20.
Rotate in the direction of the arrow using the fulcrum. As a result, the front side of the first storage chamber 4 is opened. At this time, since the support shaft 20 is deviated only from one side edge of the first door body 10, as the first door body 10 rotates, that one side edge separates from the packing 14, and the packing 14 is released.

After opening the first door body 10 in this way, insert your hand into the first storage chamber 4 and release the locking tool 17.
to release the lock from the locking piece 16.
Then, the second door body 11 is rotated about the support shaft 15 in the direction of the arrow. This opens the front surface of the second storage chamber 5. As mentioned above, the first door body 10 is removed from the packing 14 and its pressure bond is released, so that the opening operation of the second door body 11 can be performed smoothly without any resistance. I can do it.

In the above embodiment, the main body of the door device of this invention is explained using the main door of a vending machine as an example, but it is not necessarily limited to such a case, and it may be a simple case with one side open. There is no problem even if it is in the form of

[Effect of the invention] As explained above, according to this invention, when the first door body is opened, it is possible to release the pressure bonded to the packing of the second door body, and therefore the second door body can be released from the packing. The effect is that the door body can always be smoothly opened without receiving any resistance.
