Description

DETAILED DESCRIPTION OF THE INVENTION <<Field of the Invention>> The present invention relates to an improvement in a night safe, and more particularly to a night safe that is highly resistant to fraud.

≪Prior art and its problems≫ In general, night safes have a slot in the outer wall of a building, and a slot door to open and close the slot. There is a storage area for storing bags, etc.

Therefore, for such night safes,
When a customer opens the input door, an opening for a storage box into which a bag containing cash or the like is inserted appears along with the input slot.By storing the bag containing cash or the like into this box and closing the input door, the box is opened. It rotates 90 degrees downward along the inside surface of the exterior wall, and as a result, bags and other items stored in the box naturally fall and are stored inside the exterior wall, that is, in the storage space provided inside the building. It is configured to

However, since night safes are mainly used at night and after business hours when they are less popular, they need to be configured so that they can be handled quickly and with good operability. There is a need to.

However, as described above, conventional night safes are configured so that the box in which bags and the like are stored rotates 90 degrees downward along the inner surface of the outer wall. This has the disadvantage that the storage amount is small compared to the storage capacity, as the items fall and are accumulated on the outside wall side of the storage.

In order to increase this amount of storage, we have introduced a structure in which bags and other items stored in a box are lifted upwards and then dropped vertically into the storage box, or the storage box itself is built by digging into the floor of the building. However, in the former case, the bag loading position is higher, which requires either installing a step stool in front of the loading door or raising the floor itself.

In addition, in the latter case, construction work such as digging the floor is required, and in either case, extra construction costs will be required.

Furthermore, due to the structure of the conventional products mentioned above, there is no space for placing the bag vertically, i.e., along the length of the bag. Since the device is structured to be stored in a box, the input door and input port are large, which poses problems in terms of theft prevention, manufacturing, installation, and cost.

On the other hand, the following types of fraudulent acts against night safes are considered.

(1) When a bag containing cash is inserted into a night safe,
The switch in the safe will activate and a receipt will be issued to show that the bag has been received, so attach a string to the bag, insert the bag, activate the switch, issue a receipt, and then pull the string to remove the bag. After placing the items in the deposit box, the customer opens the deposit door again and takes them home, and uses the receipt obtained later as evidence to request the return of the bag containing cash that was not received in the first place.

(2) Paste double-sided adhesive tape or strong adhesive inside the deposit box, and then after the customer using the night safe puts a bag containing cash into the deposit box, closes the door, and returns home, close the door again. Open the bag and take out the bag stuck inside the input box.

In order to prevent these fraudulent acts, conventional night safes have a deposit slot and a receiving opening that are close to each other.
The input box moves downward when the input door is opened and closed.
It only rotates 90 degrees, its range of motion is close to the input port, and they are almost too integrated with each other, and the input box has no means of removing adhesive tape or adhesive once it has been applied. Due to the lack of security, the security against fraud was low and it was not possible to reliably prevent fraud.

≪Object of the invention≫ This invention was made in view of the above-mentioned circumstances, and its purpose is to prevent fraudulent activities such as fishing out bags containing cash once placed in them, and using adhesive tape or adhesives. To provide a night safe that can reliably prevent such problems, further improve the storage capacity of bags containing cash, etc. even in a night safe with an existing receiving box, and reduce the size of the input door and input slot. There is a particular thing.

<<Structure and Effects of the Invention>> In order to achieve the above-mentioned objects, the present invention provides a slot door for opening and closing a slot for a cash bag or the like formed on a wall, an opening at one end and an opening at the other end. It is rotatably attached to the inside of the wall surface so that the closed side portions alternately face the slot, and a cash bag or the like is placed along the longitudinal direction of the wall through the opening on the one end side. The input box is driven by the opening and closing operation of the input door, and when the door is opened, the opening of the input box is opposed to the input slot, and when the door is closed, the opening of the input box is reversed to close the input box. A rotary drive mechanism that makes the surface face the slot, and a sliding mechanism arranged on the inner bottom of the slot, forcibly removing a cash bag or the like stored inside the box when the slot is reversed when the door is closed. A pusher plate that slides outward and is linked to the rotational drive mechanism through the base, and a shutter plate is bent toward the tip of the base, and this shutter plate lowers when the door is first moved to close. and a shutter that shields between the input door and the closed surface of the input box, and when the door is opened, raises the shutter plate to face the input slot and the opening of the input box. .

That is, according to the present invention, the loading door and loading box are configured to be completely separated, and when the door is closed, the shutter is immediately operated to lower the shutter plate between the loading door and the loading box, thereby separating both. The shutter board is configured to completely shield the space between the boxes, and when the shutter operates when the door is opened, the shutter plate rises to face the input slot and the opening of the input box. Since the inside and outside of the slot can be shielded by this operation, it is possible to provide a night safe that is physically and psychologically difficult to commit fraud, and is highly resistant to theft.

Furthermore, as the door is closed, the opening of the input box rotates to the opposite side of the input slot, and in this state, the pusher plate provided on the inner bottom of the input box forcibly removes the stored bag, etc. Since it is configured to be pushed out of the box and dropped into the receiving box, it is possible to increase the distance between the input slot and the opening of the receiving box even in a limited space, and the bag that has been placed can be pushed out of the box and dropped into the receiving box. can be dropped from the center of the storage. Therefore, it is possible to further improve the theft protection against fraudulent activities, and even with the same storage volume as before, it is possible to efficiently store bags and the like and increase the storage capacity.

Furthermore, the input slot and input box are configured so that bags and other items can be input vertically.
It has the effect of being able to downsize the input door, input opening, etc.

<<Description of Embodiments>> Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIGS. 1 and 2 show an overall configuration diagram and a plan view of a night safe according to the present invention.

This night safe has a casing 2 that is fitted inside an outer wall 1 of a building in which a slot 1a is formed.
and a storage 3 installed at the bottom of this casing 2.
It is made up of.

The input slot 1a is provided with an input door 4 which can be opened and closed in the vertical direction about the lower edge of the opening, and a receipt ticket opening 5 is provided on the side of the input door 4.

Inside the casing 2 is the input box 7 for a cash bag or the like, which rotates about 180 degrees forward and backward about the rotating shaft 6 and has an opening 7a at one end and a closed surface 7b at the other end. It is arranged at the back of the input door 4.

This bag input box 7 is designed to store a regular cash bag W vertically (along the longitudinal direction of the bag) through an opening 7a at one end thereof.
The internal volume is set, and a pusher plate 8 having a substantially L-shaped cross section is housed in the inner bottom surface of the box 7 so as to be retractable into the box 7.

Furthermore, a chute 9 is disposed at the back of the input box 7, and its lower end opening passes through the top plate surface of the receiving box 3.

Inside the chute 9 are shafts 10 and 11, respectively.
A pair of shutter plates 12 and 13 are arranged which swing from the base point, and each of these shutter plates 12 and 13
are balanced in such a position that their swinging tips close each other, so that once a bag or the like falls inside the chute 9, each shutter plate 12,1
3 is configured to open its swinging end to drop a bag or the like into the storage 3, and then return to its original state as shown in the figure.

FIG. 3 shows a more detailed structure of the input box 7.

The pusher plate 8 disposed on the inner bottom surface of the input box 7 has an L-shaped integrated wall portion 8a at its inner depth.

This wall portion 8a has a shape that matches the inner wall surface of the input box 7, so when viewed from the opening 7a of the input box 7, the box 7 and the pusher plate 8 are recognized as an integral inner wall. .

A rack 14 is fixed to the lower surface of the center of the pusher plate 8 along its longitudinal direction, and a pinion 1 is fixed to the rack 14.
5 are engaged.

The pinion 15 is supported by a rotating shaft 16 that is rotatably supported on the bottom of the charging box 7, and as the rotating shaft 16 rotates forward and backward, the pusher plate 8 moves in and out of the charging box 7. .

Further, a scraper 17 whose both sides are fixed to both inner walls of the box 7 is arranged at the lower edge of the opening 7a of the input box 7.

The cutting edge 17a of the scraper 17 comes into contact with the surface of the pusher plate 8, and has the function of scraping off deposits on the surface of the box 7 as the pusher plate 8 moves in and out of the box 7.

Furthermore, a shutter 18 is attached to one end of the rotating shaft 6, as shown in FIG.

The shutter 18 includes a substantially fan-shaped base 19 that is loosely fitted onto one end of the rotating shaft 6, and a shutter plate 20 that is bent into an L-shape toward the tip of the base 19.
It is made up of.

The shutter 18 is connected to an intermittent gear 22 via a connecting rod 21, and the intermittent gear 22 meshes with a large diameter intermittent gear 23 mounted on the rotating shaft 6. The shaft portion 24 of 22 is rotatably supported on the inner wall of the casing 2.

Further, a tension spring 25 is suspended between the connecting rod 21 and the inner wall of the casing 2, and the shutter plate 20 always urges the shutter 18 in a direction to close the input port 1a.

When the input box 7 rotates clockwise around the rotating shaft 6, the intermittent gear 2
2 rotates counterclockwise, and as a result, the shutter 18 is rotationally driven toward the input port 1a, and the shutter plate 20 is moved between the opening 7a of the input box 7 and the input door 4.
When the loading box 7 continues to rotate clockwise, the intermittent gears 22 and 23 disengage, and the shutter plate 20 closes to the loading door 4.
The contact position is maintained only by the biasing pressure of the spring 25.

The loading box 7, pusher plate 8 and shutter 18 are linked to the opening/closing operation of the loading door 4, and when the door is opened, the pusher plate 8 is housed in the loading box 7 and the loading door 4 is opened and closed. The opening 7a of the box 7 is located on the side of the input port 1a, and when the door is closed, the input box 7 is rotated 180 degrees around the rotating shaft 6 and pushed by the rotation of the rotating shaft 16, as shown in the figure. Push out the plate 8 from inside.

Further, the shutter 18 is operated relatively early after the start of closing the door (at the time of the initial closing operation), and the shutter plate 2
0 and close the input port 1a side.

These series of operations are performed in conjunction with only the opening and closing operations of the loading door 4, as described above.
Next, the detailed rotational drive mechanism will be explained using the drawings from FIG. 5 onwards.

In FIGS. 5 to 7, the pivot shaft 4 of the input door 4
A sector-shaped drive gear 26 is attached to the extended end of a, and this gear 26 is connected to a driven gear integrally provided on the other end side of the rotating shaft 6 of the input box 7 via an idle gear 27. It meshes with 28.

The tooth ratio of the fan-shaped gear 26 and the driven gear 28 is set to approximately 2:1, and the opening/closing operation of the input door 4
In contrast to the forward and reverse rotation of 90 degrees, the input box 7 is configured to rotate approximately 180 degrees in the forward and reverse directions.

A gear (not shown) is provided on the extension of the shaft 16 for moving the pusher plate 8 in and out. It is configured to mesh with the internal gear 29.

In the open state of the loading door 4 shown in FIG. 5, the opening 7a of the loading box 7 is aligned with the opening surface of the loading slot, and the shutter plate 20 of the shutter 18 is in the raised position.

From this state, put the bag W into the storage box 7 in a vertically elongated shape, and then start closing the door 4 as shown in FIG. In the closed state, Part 2
Rotate to twice the 90° position.

Further, at a stage before that, the shutter 18 moves downward, and the shutter plate 20 completely isolates the loading door 4 and loading box 7. For example, the tooth ratio of the intermittent gears 22 and 23 is set so that the shutter plate 20 of the shutter 18 is completely closed when the input door 4 is tilted approximately 20 degrees from its fully open state.

In this position, a gear provided on an extension of the pinion 15 meshes with the internal gear 29, whereby the pinion 15 rotates and moves the rack 14, and the pusher plate 8 holds the bag W. In this state, it starts to protrude from the input box 7.

Furthermore, when the loading door 4 is completely closed as shown in FIG. The weight of the bag W opens the shutter plates 12 and 13 at the top of the storage 3, and the bag W is dropped into the storage 3.

A limit switch 30 is provided on one of the shutter plates 13, and the switch 30 is operated by the opening operation of the shutter plate 13, and in response to this operation, a receipt is issued to the receipt ticket issuing port 5 from a receiver (not shown). Become.

As described above, according to the present invention, by reversing the input box 7, the bag stored in the input box is forcibly taken out from the inside of the input box in a state where it has rotated further into the input opening and is then stored in the storage box. Since the shutter is linked to the rotary drive mechanism that drives the loading door and loading box, the shutter plate moves up and down and blocks the inside of the loading opening. This makes it extremely difficult to commit fraudulent acts, both physically and psychologically.

Furthermore, as the door is closed, the input box rotates to the opposite side of the input slot, and in this state, the pusher plate installed inside it forces out the bag containing cash, etc. Since the bag is configured to fall into the storage compartment, it is possible to make effective use of the limited space and increase the distance between the input slot and the opening of the storage compartment. etc. can be dropped from the center of the storage. Therefore, according to the night safe according to the present invention, it is possible to further improve theft prevention performance against fraudulent acts, and even with the same storage volume as before, it is possible to efficiently store bags containing cash and increase the storage capacity. can.

Furthermore, the input slot and input box are configured so that bags etc. can be input vertically.
It has the effect of being able to downsize the input door, input opening, etc.

In addition, in the above embodiment, the rotation angle of the input box with respect to the input door is approximately 180 degrees compared to 90 degrees.
These ratios can be set arbitrarily by changing the gear ratio.
