Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an emergency ventilation system for a vault, which is useful when a person is trapped inside the vault.

Since the items stored in a safe are valuables such as cash, precious metals, or important documents, the inside and outside of the safe must be completely shut off when the safe door is closed. Moreover, it needs to have a strong and strong structure that can withstand sabotage from the outside. It is also necessary to have a watertight structure so that water used for cleaning outside the vault or in the event of a fire does not leak into the interior of the vault. Furthermore, in case a thief lurks inside, it must naturally be impossible to open the safe door from the inside. Therefore, in the unlikely event that someone is inadvertently trapped inside the vault, oxygen deprivation will inevitably result in personal injury. Therefore, to prevent personal injury due to lack of oxygen, to issue an alarm outside to call someone and make it possible to communicate with the outside world, and to supply emergency supplies such as food and drinks to the safe room as needed, we installed an emergency ventilation system. Requires installation. Moreover, oxygen depletion occurs, and when a person feels the lack of oxygen, their body becomes paralyzed and their movements become slow, so in a small room like a vault, it is necessary to open the ventilation holes as soon as possible. , the operation should be as simple as possible.

However, few conventional emergency ventilation systems have a structure that is also watertight, and in devices that have 2 or 3 watertight properties, the watertight mechanism must be released first to open the ventilation holes. This required a two-step operation, in which the ventilation hole had to be opened after the first operation. In addition, there is a device that allows these operations to be performed in one step, and is made watertight by inserting a plug in the ventilation hole to close the ventilation hole. Since the plug or the connecting rod connected to the plug remains inside the hole or in the extension area of the ventilation hole, it is unsuitable for supplying emergency supplies.

The present invention has been made in consideration of the above-mentioned problems, and is designed to provide effective watertightness during normal times.
To provide an emergency ventilation system for a vault, which isolates the interior and exterior, ensures communication between the interior and exterior of the vault with simple operation in an emergency, and also enables the supply of emergency supplies such as food and drinks. This is the purpose.

In order to achieve this object, the device of the present invention includes a pair of hollow members embedded in the wall of a safe and communicating between the inside and outside of the safe, and an end surface of the pair of hollow members on the inside side of the safe that is slidable. and a barrier plate that is detachably attachable to the end face, a barrier plate retainer plate that is detachably attachable to the barrier plate, and an operation unit that can attach and detach the barrier plate presser plate and the barrier plate and slide the barrier plate. When the barrier plate and the barrier plate holding plate are crimped together, the barrier plate is crimped to the end surfaces of the pair of hollow members, and when separated, the barrier plate is separated from the end surfaces, and the sliding of the barrier plate causes the pair of hollow members to The members are opened and closed, and the crimped barrier plate presser plate is separated from the barrier plate by a series of operations of the operating section, and the barrier plate is separated from the end faces of the pair of hollow members, and then the barrier plate is removed. The hollow member is opened by sliding the hollow member.

Hereinafter, the structure and operation of the apparatus of the present invention will be described in detail based on the illustrated embodiments.

In the figure, numeral 3 is a main body plate on which a pair of hollow members 2a and 2b are protruded in parallel, and through holes are formed to fit into the hollow portions of the hollow members 2a and 2b, respectively. The hollow members 2a and 2b are embedded in the wall 1 of the vault with the main body plate 3 facing the interior A so that the interior A and the exterior B of the vault are communicated through the hollow members 2a and 2b. . Among the communication parts formed by the hollow parts, the upper one is a communication hole 4a, and the lower one is a ventilation hole 4.
It is listed as b. An O-ring 3 with a diameter slightly larger than the diameter of the communication hole 4a and the ventilation hole 4b is placed on the board surface of the inside A side of the vault of the communication hole 4a and the ventilation hole 4b.
c, 3c are worn.

In the figure, reference numeral 5 denotes a shield plate, which has a through hole 5a overlapping with the communication hole 4a and an elongated hole 5b into which a pin 8a of a replacement plate 8, which will be described later, is loosely inserted. It is supported by a pin 8a, which will be described later, so as to slide on the surface on the inside A side of the chamber. As shown in FIG.
It is formed to extend in one direction from the center line in the sliding direction. By sliding the barrier plate 5, the through hole 5a is positioned overlapping with the communication hole 4a to communicate the inside and outside A and B of the vault, and at the same time, the end of the barrier plate 5 is positioned above the communication hole 4a. Evacuate from the area where the ventilation hole 4b is extended to the inside A side of the vault and open the inside and outside A and B of the vault.
communicate. In other words, the barrier plate 5 is slidable up and down so as to simultaneously close or open a pair of upper and lower communication holes (communication hole 4a, ventilation hole 4b), and the left and right positions of the barrier plate 5 are adjusted to guide the sliding movement. Guide members 5g and 5g are positioned at .

Furthermore, a barrier plate receiving member 3a is provided protrudingly from the lower end of the main body plate 3, and the barrier plate receiving member 3a has an abutment seat that contacts the lower end surface of the barrier plate 5 at the lower sliding end position of the barrier plate 5. 3b is provided protrudingly. It is preferable that the abutment seat 3b is made of an elastic material such as rubber. Further, a guide rod 3g is protruded from the shield plate receiving member 3a, and a guide hole 5h into which the guide rod 3g is inserted is formed on the lower end surface of the shield plate 5, and cooperates with the guide members 5g, 5g to prevent the shield Board 5
It is preferable to guide the sliding movement of the shield plate 5. Furthermore, it is preferable to fit a compression coil spring 3s into the guide rod 3g and apply the restoring force of the compression coil spring 3s in the upward sliding direction of the shield plate 5, so that the operation described later can be performed. This is desirable for smooth implementation. Of course, the guide members 5g, 5g may be used to guide the barrier plate 5, or the guide rod 3g may be used to guide the barrier plate 5.
There is no problem in guiding by a combination of the guide hole 5h and the guide hole 5h.

Next, the operation section for sliding and attaching/detaching the above-mentioned shield plate 5 will be explained.

In the figure, reference numeral 6 denotes a barrier plate holding plate that can be crimped onto and removed from the surface of the barrier plate 5 on the inside A side of the vault, and in this crimped state, the barrier plate 5 is also crimped to the main body plate 3 at the same time.
This attachment/detachment is performed by rotating a push shaft 7 having a threaded portion 7a that is screwed into the barrier plate holding plate 6.
The push shaft 7 is inserted into and pivotally supported by a cylindrical bearing member 8c fixed on the surface of the exchange plate 8 on the side A inside the vault. Further, a guide piece 8b is fixed to one end of the surface of the exchange plate 8 on the side B facing outside the vault. The guide piece 8
The guide surface 81 of b engages with one end surface of the above-mentioned barrier plate holding plate 6, and slides and guides the one end face to ensure attachment/detachment between the barrier plate holding plate 6 and the protection plate 5. I'm trying to get it. A pin 8a is provided protrudingly on the surface of the guide piece 8b on the side B facing outside the vault, and the pin 8a is loosely inserted into the elongated hole 5a of the shield plate 5. Also,
It is desirable that the pin 8a be a roller that can rotate within the elongated hole 5b of the barrier plate 5.

9 in the figure is the middle plate, and there is a safe on the peripheral edge of the main body plate 3.
Main body frame plate 3 erected and fixed facing toward the indoor A side
1, 31... is mounted at an appropriate distance from the main body plate 3, and has a through hole that fits into the outer periphery of the bearing member 8c of the exchange plate 8 and a through hole that overlaps with the communication hole 4a. There is. If an auxiliary hollow member 9a is provided in the through hole that overlaps with the communication hole 4a, oriented toward the outside B of the vault and extends to a position that forms a sufficient space for the shield plate 5 to slide, Desirable for those making calls. The bearing member 8c is fitted into a through hole that fits into the outer periphery of the bearing member 8c, and the exchange plate 8 is rotatably supported relative to the middle plate 9 and the main body plate 3. In this case, it is preferable to support the bearing member 8c via a metal 10 such as an oil-less metal rather than directly fitting the bearing member 8c into the through hole. Therefore,
The push shaft 7 described above is rotatable with respect to the middle plate 9 and the main body plate 3 via the bearing member 8c, and is also rotatable with respect to the exchange plate 8. The central axis of rotation of the push shaft 7 is the same axis. Further, the barrier plate 5, the barrier plate holding plate 6, and the replacement plate 8 are located between the main body plate 3 and the middle plate 9.

One end of the bearing member 8c of the exchange plate 8 is made to protrude further toward the inside A side of the vault than the plate surface of the middle plate 9, and a cylindrical cam 11 is fitted and fixed to the protruded portion. Therefore, the exchange plate 8 rotates when the cylindrical cam 11 rotates. Further, the end of the push shaft 7 is made to protrude further toward the inside A side of the vault than the end face of the bearing member 8c of the exchange plate 8, and the handle knob 12 is fitted and fixed in the protruded part. . Therefore, the rotation of the push shaft 7 is caused by the rotation of the handle knob 12. On the surface of the cylindrical cam 11 on the side A inside the vault, there is a gentle slope 11 with respect to one direction in the circumferential direction.
A is formed with a steep slope 11b in the opposite direction. In addition, a cylinder 12a is formed in the handle knob 12 in the axial direction of the push shaft 7, and a piston 12b is fitted into the cylinder 12a, and a compression coil spring 12c causes the piston 12b to have a forced sliding force in the direction B outside the vault. is giving. Then, the tip of the piston 12b is connected to the cylindrical cam 1.
The piston 12b comes into contact with a surface forming a gentle slope 11a and a steep slope 11b, and the piston 12b slides while being guided by the respective slopes. In this case, it is preferable that the handle knob 12 is fitted with a cylindrical cam 11 as shown in FIG.

In the figure, reference numeral 13 denotes an external box body provided on the wall surface on the outside B side of the vault, which has through holes into which the hollow members 2a and 2b are fitted. The external box body 13 has threaded parts 20a, 20b cut at the ends of the hollow members 2a, 2b.
It is held between lock nuts 14a and 14b which are screwed together. Further, reference numeral 15 in FIG. 4 is a positioning seat plate, which securely fixes the device of the present invention to the wall 1 by tightening the lock nuts 14a and 14b, and also facilitates installation on the wall 1 of an existing vault. There is.

In the figure, reference numeral 16 denotes a fan installed facing the ventilation hole 4b, which promotes ventilation within the vault. Further, reference numeral 17 shown in FIG. 2 is an insertion hole through which a cord for equipment such as the fan 16 is inserted, and after insertion, it is embedded using a sealant such as silicone.

Since the configuration of the device of the present invention has been clarified through the above explanation, its operation will be described below.

1 to 3 represent the positions of the various parts of the present invention in its normal state, that is, when no person is confined within the vault. In an emergency when a person is trapped, the person turns the handle knob 12 clockwise in FIG. 3.
Due to this rotation, the tip of the piston 12b of the handle knob 12 is guided along the gentle slope 11a of the cylindrical cam 11, so the push shaft 7 is rotated without rotating the cylindrical cam 11, and the The barrier plate presser plate 6 screwed onto the push shaft 7 is moved back in the direction of separating from the barrier plate 5 (in the direction of arrow P in the top of FIG. 2). In this case, the lower end surface of the barrier plate holding plate 6 engages with and is guided by the guide surface 81 of the guide piece 8b of the exchange plate 8, so that the barrier plate holding plate 6 rotates together with the push shaft 7. The body plate 3 of the protection plate 5 moves backward without any problem and finally comes into contact with the replacement plate 8.
The pressure bonding to the shield plate 5 is released, and the barrier plate 5 becomes able to slide. Therefore, if the handle knob 12 continues to be rotated further, the frictional force between the protection plate holding plate 6 and the replacement plate 8 and the force between the lower end surface of the protection plate holding plate 6 and the guide surface 81 of the guide piece 8b of the replacement plate 8 will be reduced. The engagement rotates the exchange plate 8 clockwise in FIG. 3. As the exchange plate 8 rotates, the pin 8a of the exchange plate 8 moves against the barrier plate 5.
It turns around the bearing member 8c while being guided by the elongated hole 5b, and pushes the barrier plate 5 upward in FIG. 3. This allows the through hole 5a of the barrier plate 5 to pass through.
It is positioned so as to overlap the vent hole 4a, and the shield plate 5 is retracted from the position blocking the ventilation hole 4b, so that the inside A and the outside B of the vault are communicated with each other.

After that, if the trapped person issues an alarm to the outside and turns on the switch (not shown) for the fan 16 to operate the fan 16, the trapped person can breathe easily and prevent personal injury. Alternatively, it is also possible to provide a micro switch having a detection terminal that abuts against the shield plate 5 at the upper sliding end position of the shield plate 5, and to operate the fan 16 by closing the micro switch. Even in this case, if a manual switch is also provided so that the trapped person can start and stop the fan 16, the fan 16 will be stopped when making a call, and the noise will not disturb the call. Very desirable.

In addition, in order to set the above-mentioned state where the inside A and the outside B of the vault are in communication to the normal state, that is, the state where the communication hole 4a and the ventilation hole 4b are closed, turn the handle knob 12 in the counterclockwise direction in FIG. All you have to do is rotate it. That is, as a result of this rotation, the pin 12b of the handle knob 12 engages with the steep slope 11b of the cylindrical cam 11, causing the cylindrical cam 11 to rotate counterclockwise and the exchange plate 8 to rotate counterclockwise as well. Then, the shield plate 5 is moved downward and positioned to close the communication hole 4a and the ventilation hole 4b. When the shield plate 5 is positioned at this position, the pin 8a comes into contact with the right end of the elongated hole 5b of the shield plate 5, and the replacement plate 8 can no longer be rotated counterclockwise. Therefore, if the handle knob 12 continues to be rotated, the piston 12b will be guided by the steep slope 11b of the cylindrical cam 11 and will move in the direction A inside the vault, releasing its engagement, and the cylindrical cam 11 will rotate. The push shaft 7 can be rotated without moving. As the push shaft 7 rotates, the barrier plate holding plate 6 screwed thereto is advanced in the direction opposite to P in FIG. 5 to the main body plate 3 to form communication holes 4a and ventilation holes 4b.
This will end up blocking the area.

By blocking the communication hole 4a and the ventilation hole 4b, the interior A and exterior B of the vault are ensured to be watertight, but
Since O-rings 3c, 3c are attached around the communication hole 4a and ventilation hole 4b on the plate surface of the main body plate 3,
Watertightness can be further improved.

As described above, the device of the present invention includes a pair of hollow members embedded in the wall of the safe and communicating between the inside and outside of the safe, and a pair of hollow members that are slidable on the end faces of the pair of hollow members on the inside side of the safe. Consisting of a barrier plate that is detachable from the end face, a barrier plate presser plate that is detachably attached to the barrier plate, and an operation unit that can attach and detach the barrier plate presser plate and the barrier plate and slide the barrier plate, When the barrier plate and the barrier plate holding plate are crimped together, the barrier plate is crimped to the end faces of the pair of hollow members, and when separated, the barrier plate is separated from the end faces, and the sliding of the barrier plate causes the barrier plate to press against the end faces of the pair of hollow members. Opening and closing are performed, and a series of operations of the operating section causes the crimped barrier plate presser plate to separate from the barrier plate, and the barrier plate to separate from the end faces of the pair of hollow members, and then slide the barrier plate. Since the hollow member is opened by moving the vault, if a person is trapped inside the vault, the communication hole and ventilation hole that communicate the inside and outside of the vault can be opened with a simple operation. This prevents the oxygen in the safe from being depleted and thereby prevents personal injury. In addition, there are no obstacles left inside the communication hole, etc.
It is possible to easily supply emergency supplies such as food and drinks into the safe. Moreover, during normal times, the openings of the communication hole and ventilation hole are closed by crimping the shield plate, so the inside and outside of the vault are reliably isolated, and water used for cleaning the outside of the vault or extinguishing a fire does not flow into the inside of the vault. It was possible to provide sufficient watertightness to prevent water from leaking into the container, and therefore, it was possible to achieve a practically effective effect.
