Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an opening/closing device in, for example, a storage device.

[Prior art and its problems]

Conventionally, for example, a storage device is equipped with a loading door that opens and closes an opening provided on the outer wall of a building, and a customer opens the loading door, places a bag inside, and closes the loading door, thereby allowing the customer to store the bag. is configured to be dropped into a storage room provided inside the building.

For this reason, in such conventional storage devices, the input slot and the storage chamber are close together, making it easy for unauthorized acts such as fishing for bags, and there is a lack of certainty regarding theft prevention. There are some drawbacks.

In particular, since the input slot and the storage chamber are close to each other, when bags are inserted, they tend to accumulate at the front of the storage compartment (on the input slot side). The accumulated upper bag makes it extremely easy for illegal acts such as fishing to be carried out.

Therefore, in order to solve these drawbacks, the second
As shown in the figure, a loading door 1 is rotatably attached to an opening formed in a wall and opens and closes the opening;
an article input box 2 with an open end, which is rotatably disposed inside the wall and facing the opening;
a mechanism (not shown) for reversing the input box in conjunction with the opening/closing operation of the input door 1; a pusher plate 3 retractably housed inside the input box 2; The pusher plate 3 is provided with a mechanism (not shown) for moving the pusher plate 3 into and out of the input box 2 in conjunction with the reversing operation of the input box 2, so that when the door is opened, one end opening of the input box 2 is positioned facing the pusher plate 3. 3 into the inside of the input box 2, and at the same time, the opening of the input box 2 is reversed when the door is closed.
A night safe has been proposed in which a pusher plate 3 is made to protrude from the input box 2 so that the inserted articles held on the pusher plate 3 are forcibly discharged into the storage chamber 4 (Japanese Patent Application Laid-open No. 154280/1983). has been done.

However, in the case of this proposal, the loading door 1
Since the movements of the input box 2 and the input box 2 are linked, that is, the input door 1 is always closed when the input box 2 rotates to drop the input items into the storage chamber 4. However, it is not possible to confirm whether or not the inserted article has completely fallen into the storage chamber 4, and there remains concern about its reliability.

For example, if the input item is a bag with a string attached, if the string gets caught on something, the input box 2 will rotate and the input item will be thrown into the storage chamber 4. Even when it is time to drop the item, it will not be dropped and will remain in the input box.
There is a risk that the input items will be taken away by the next person who opens the input door.

In other words, since conventional storage devices have only one opening door, the reliability of storage and storage performance is low.

[Means for solving problems]

The present invention has been made in view of the above points,
In other words, the inventor thought that the above-mentioned problems would be solved if there were multiple doors leading up to the loading/unloading port of the storage room, but if only multiple doors were provided, it would be difficult to open and close the door. I thought that the number of parts for the mechanism would increase and the cost would be high, and I also took great pains to figure out how to prevent accidents such as getting stuck with my hand when opening and closing the door. It was devised as a result of research on a drive means, a first arm and a second arm disposed on the rotation axis of the drive means, and a rotation of the first arm. a first shutter plate having an opening connected to the first arm so as to be actuated to close and open; and a second shutter plate that is actuated to be opened and closed by rotation of the second arm. The second shutter plate is connected to the arm of the second shutter plate, and the second shutter plate is opened after the closing operation of the first shutter plate, which is operated by the rotation of the rotation shaft of the drive means. He invented an opening/closing device equipped with a mechanism for

〔Example〕

FIG. 1 is an explanatory diagram of one embodiment of the opening/closing device according to the present invention.

In the figure, 11 is an outer wall of the building, and 12 is a door provided at a window of this outer wall 11.

Reference numeral 13 denotes a storage chamber provided inside the outer wall 11. A door is provided at the rear of the storage chamber 13, and by opening this door, items that have been dropped inside can be taken out. It's summery.

14a and 14b are shutter plates, of which the shutter plate 14a is disposed at the rear of the door 12, and the shutter plate 14b is disposed at the opening end of the storage chamber 13. has been done.

Although no opening is formed in the shutter plate 14b, an opening 15 is formed in the shutter plate 14a.

The shutter plates 14a, 14b also have grooves 16a, 16a, 16a, 14b, in which pieces, which will be described later, are inserted into the upper part of the shutter plates 14a, 14b.
6b is configured.

17 is a motor; 18 is a rotating shaft of this motor 17; a first rotating arm 19a is fixed to one end of this rotating shaft 18; A piece 20a that fits into the groove 16a is attached.

A ring is fixed to the other end of the rotating shaft 18, and a pin 21 is implanted at the tip of the ring.

Further, the cylindrical portion 22 of the second rotating arm 19b is inserted into the ring, and in this inserted state, a longitudinal hole 23 is formed along the circumferential direction at the position where the pin 21 is disposed. ing. Note that when the second rotating arm 19b is located at the position shown by the solid line in FIG. , the pin 21 does not come into contact with the end of the hole 23 for a while after the motor 17 is driven to rotate the rotation shaft 18 in a predetermined direction and the pin 21 begins to rotate.
After the pin 21 is rotated by a certain angle, the pin 21 is hooked to the end of the hole 23, and due to this hooking relationship, the rotational force of the rotation shaft 18 is transmitted to the second rotation arm 19b. The movable arm 19b is configured to rotate. In other words, the rotation shaft 18 rotates, thereby causing the first and second rotation arms 19
a and 19b rotate in the same direction, and the shutter plate 1
4a and 14b, but since the first rotating arm 19a is fixed to the rotating shaft 18, the shutter plate 14a immediately moves upward as the rotating shaft 18 rotates. The rotational force from the rotation shaft 18 to the second rotation arm 19b is not applied until the pin 21 is latched to the end of the hole 23 from a loose relationship, and therefore, the shutter plate 14b does not move upward during that time. First, the shutter plate 14b is configured to move upward only after a certain period of time.

24 is a coil spring, and this coil spring 24
One end of the coil spring 24 is hooked to the second rotating arm 19b, and the other end of the coil spring 24 is attached to the motor 1, for example.
7 side, and the second rotating arm 19b
is biased to the solid line position in FIG. 1 (the closed position of the shutter plate 14b).

Also, a piece 2 is provided at the tip of the second rotating arm 19b.
A piece 20b similar to 0a is attached, and this piece 20b is fitted into the groove 16b.

25 is a telescoping passage arranged between the shutter plate 14a and the shutter plate 14b;
This telescoping passage 25 has a cylindrical body 25 having a substantially square cross section.
₁ , 25 ₂ , 25 ₃ . . . 25n are arranged in series.

These cylindrical bodies 25 ₁ , 25 ₂ , 25 ₃ ...25n
has an outwardly projecting flange 26 at its front end.
₁ , 26 ₂ , 26 ₃ ...26n are integrally provided, and among these cylinders, the shutter plate 14
The cylindrical body 25 ₁ closest to a has a flange 26 ₁ protruding inward to form a hooking portion 27, and on the outer wall surface of the cylindrical bodies 25 ₁ , 25 ₂ , 25 ₃ . . . 25n. are the grooves 28 ₁ , 28 ₂ , 28 ₃ ...28n
is formed.

Moreover, these cylinder bodies 25 ₁ , 25 ₂ , 25 ₃ ...2
5n have slightly different sizes in the radial direction, that is, the outer diameter of the cylinder 25 ₁ closest to the shutter plate 14a is different from that of the cylinder 2 adjacent to this cylinder 25 ₁ .
When the cylindrical body 25 ₁ , which is configured to have approximately the same inner diameter as the cylinder 25 2 and is located closest to the shutter plate _14a , is moved to the right in the figure, the cylindrical body 25 ₁ is inserted into the cylindrical body 25 ₂ and The cylinder 25 ₂ in which the cylinder 25 ₁ is housed is inside the cylinder 25 ₃ , and in turn the cylinder 25 _o-1 is inside the cylinder 25 n.
It is configured to be stored inside.

In other words, when the telescoping passage 25 is fully extended, the adjacent cylindrical bodies are only fitted at their ends, but when the telescoping passage 25 is contracted, the cylindrical bodies 25 ₁ are The cylinder 25 ₂ is inside the cylinder 25 2, the cylinder 25 o- ₁ is inside the cylinder 25 ₃ , and the cylinder 25 _o-1 is inside the cylinder 25 2.
5n, most of them are accommodated and fitted within the 5n.

Further, the flanges 26 ₂ , 26 ₃ . _. . 26n have grooves _{28 1 , 28 2 ,} 28 ₃ .
A _hole is formed corresponding to the position 8n, and pins 29 ₂ , 29 _{3 ,} 29 ₄ . 29 ₃ is in the groove 28 ₂ portion, and the pin 29 n is movable while being guided in the groove 28 _o-1 portion.

30 is a driving member of the cylinder 25 ₁ attached to the end of the flange 26 ₁ ;
0 is screwed onto the shaft 31, and the shaft 31 is rotated by the force of the motor.
The drive member 30 is configured to move in the front-rear direction (left-right direction in the figure) by rotating, thereby moving the cylindrical body 25 ₁ in the front-rear direction.

In addition, 32 is a flange 26 ₁ , 26 ₂ , 26 ₃ . . .
...26n, and serves as a guide member for the cylindrical bodies 25 ₁ , 25 ₂ , 25 ₃ ...25n.

To explain the operation of the above device when it is used as a night safe, for example, when a customer with a bag containing cash first opens the door 12 using the key he/she holds, the shutter plate 14a lowers. The opening 15 of the shutter plate 14a is connected to the cylindrical body 2.
₅₁ and the shutter plate 14a is in the open state, so if you place the bag from inside the cylinder ₂₅₁ to the rear cylinder and turn on the switch in this state, the motor 17 will start operating. Rotation axis 18
is rotated, and in conjunction with this, the first rotating arm 19a begins to rotate, and due to the engagement relationship between the groove portion 16a and the piece 20a, the shutter plate 14a rises to the closed state, and, When the shutter plate 14b rises with a delay in the rising movement of the shutter plate 14a, that is, the pin 21 begins to rotate due to the rotation of the rotation shaft 18 and reaches a predetermined position (corresponding to the half-closed state of the shutter plate 14a). 21 is hooked to the end of the hole 23 from the idle state to rotate the second rotation arm 19b in the same direction as the rotation direction of the first rotation arm, and by the rotation of the second rotation arm. The shutter plate 14b rises to the open state, and
Along with these operations, the shaft 31 rotates and the cylindrical body 25 ₁
By applying a force in the rearward direction (to the right in the figure) to the cylinder body 25
₁ is moved rearward, the cylinder 25 ₁ gradually fits into the cylinder 25 ₂ , and the flange 26 ₁ of the cylinder 25 ₁ comes into contact with the flange 26 ₂ of the cylinder 25 ₂ or the front end of the groove 28 ₁ When the pin 29 ₂ is hooked to the part, the cylinder 25 ₂ receives the force exerted by the cylinder 25 ₁ due to this relationship, so the cylinder 25 ₂ begins to move backward, and then Through a similar movement, the cylinder 25o _-1 comes to be fitted into the cylinder 25n, and finally the cylinder 25n is placed in a position with the rear end of the cylinder 25n at a slightly rearward position (a little more than the shutter plate 14b). In connection with the movement of these cylinders, the bag hooked on the hook 27 of the cylinder ₂₅₁ is also moved rearward, and the bag that has been transferred rearward is moved backwards. Depending on the position of the center of gravity or the scraping means provided at the rear of the cylindrical body 25n, the bag is discharged and dropped into the storage chamber 13 and stored therein.

When the bag is ejected from the cylindrical body 25 ₁ , the shaft 31 begins to rotate in the opposite direction to that in the above case, and as a result, the driving member 30 moves forward (to the left in the figure), so that the cylindrical body 25 1 ₁ moves forward, and when the pin 29 ₂ disposed on the cylinder 25 ₂ engages with the rear end of the groove 28 ₁ formed on the outer wall of the cylinder 25 ₁ , this engagement relationship Therefore, cylinder body 25 ₂ also cylinder body 2
The cylinders 25 _{3 ,} . . . , 25n are moved, and the telescoping passage 25 is extended and returned to its original state.

When this return state is reached, the motor 17 begins to rotate in the reverse direction, and the shutter plate 14b descends (at the time of this descent, the rear end of the cylinder 25n is moving forward, so the rear end of the cylinder 25n is moved forward). In other words, by the rotation of the rotation shaft 18, the second rotation arm 19b immediately begins to rotate in the opposite direction to that in the above case, and the elastic force of the coil spring 24 The shutter plate 14b is immediately lowered into a closed state, closing the rear part of the telescopic passage 25, and the shutter plate 14a is lowered to close the opening of the shutter plate 14a. 15 is the cylinder body 25
It matches the part ₁ and is in the open state, and the door 12
It will be in the same state as when you first opened it.

After confirming that there is nothing in this telescoping passageway 25, the customer closes the door 12 and completes the series of operations.

According to the above-mentioned storage device, it becomes possible to load the input, for example, in a deep position behind the input port, that is, the position of the door 12, and even if the door 12 is opened, the storage can be carried out from this door part. Room 1
Fraudulent acts such as fishing for bags stored in the device become impossible, and security is significantly improved.

Moreover, unlike the conventional method as shown in FIG. 2, for example, if a telescoping passage means is used as a means for discharging from the position of the door 12 to a deep position behind, Since no space is required, the space in the vertical direction can be small, and the size can be substantially reduced accordingly, so that restrictions on the installation location of the storage device of the present invention can be relaxed.

In particular, even in cases where there is not enough equipment space in the vertical direction, the loading depth position in the depth direction can be adjusted appropriately by simply adjusting the number of cylinders, making it possible to create a storage device that is highly safe for stored items. can be provided at low cost.

In addition, for example, since it is possible to confirm later whether or not a bag has been placed in the storage chamber, the door 12 can be closed after confirming that the bag has been placed in the storage chamber, as shown in FIG. Unlike the conventional case where the bag is dropped into the storage compartment due to some accident,
If the next person opens the door and grabs the previous person's bag, there will be no chance of it being stolen, making the door that much safer.

Also, when the telescoping passage is contracted, the cylinder 25 ₁ on the door 12 side is inside the cylinder 25 ₂ , the cylinder 25 ₂ is inside the cylinder 25 ₃ , and so on. Since the body is designed to be fitted inside, there is no chance of something getting caught between the cylinders and causing a malfunction, which increases the reliability of the device. .

Further, shutter plates 14a and 14b are provided, and when one is in an open state, the other is in a closed state,
Therefore, it is impossible to look into the storage chamber from the door 12, and the reliability of the storage device is increased accordingly.

Further, since the shutter plate 14a provided in the area where a bag is put is opened when the shutter plate 14a is lowered, even if the shutter plate 14a suddenly lowers, your hands will not be caught, thus preventing personal injury. I've learned not to wake up.

In addition, since the shutter plates 14a and 14b move in the same direction, one operating in the opening direction and the other in the closing direction, the shutter plates 14a and 14b can be operated with one operating mechanism, and the structure is simple. Fewer parts required.

Further, since the shutter plate 14b is provided with a coil spring 24, which always biases the shutter plate 14b in the closing direction, the closing operation of the shutter plate 14b is quick and smooth. Even if it rotates too much due to inertia, it will close temporarily because it is biased in the closing direction by the coil spring 24 →
The shutter plate 14b is large as shown from open to close.
The shutter plate 14b can be closed smoothly without shaking.

Further, when the shutter plate 14b is opened upward, the cylinder 25 is placed in the descending passage of the shutter plate 14b.
Since the rear end of cylindrical body 25n is located
The rear end portion serves as a stopper, and even if the shutter plate 14b were to fall for some reason, there would be no problem at all.

〔effect〕

The first shutter plate and the second shutter plate are configured so that when one is open, the other is closed, so it is impossible to see inside, and the reliability of theft prevention is reduced. In particular, the second shutter plate is configured to open after the first shutter plate closes, making it even more difficult to see inside, and the reliability of theft prevention is poor. Moreover, since there are multiple shutter plates, even if one shutter plate is torn, there is still a shutter plate, so the reliability of theft prevention is higher, and the operating direction of the first and second shutter plates is higher. Even if they are the same, one shutter plate is open and the other is closed, so the means for driving the first shutter plate and the second shutter plate can be simplified. The related operation with the shutter plate can be ensured, which means that for some reason it is completely impossible to make a mistake where one side is opening when the other is opening, and the reliability is that much higher. Furthermore, the first shutter plate, which may be touched by hands, closes when it moves up and opens when it moves down, so if the stopper means for the first shutter plate comes off for some reason. If a person's hand is caught, no personal injury will occur, and it is extremely safe.
