DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a burglarproof structure for storages such as safes for offices, warehouses and homes, and storage shelves.

[0002]

2. Description of the Related Art Storage boxes, such as safes and storage shelves, store items such as valuables and documents inside a box-shaped main body with an open front, and open and close a door or drawer that can open and close the opening of the main body. By covering with a free drawer, the stored items are protected from fire and theft.

In an ordinary safe, a door is supported on one side of an enclosure wall of an opening portion of the main body so as to be openable and closable. The door is detachable from an edge of the enclosure and is horizontally moved by a moving means such as a handle. Locking means such as a cylinder lock, a dial lock, etc., which regulate the operation of the moving means and the bar which is moved in the direction or the vertical direction are provided. With this configuration, the moving means is operated by closing the open portion of the main body with the door, and the locking means is operated after the door is fixed to the main body by engaging the bar with the edge of the surrounding wall, thereby moving the moving means. The operation of the means is regulated and the door is completely locked to the body. At this time, the bar is fitted into the side wall of the main body by about 20 mm.

In a normal storage library, a drawer having substantially the same capacity as the space inside the main body is supported on the side wall of the main body so as to be able to be pulled out, and this drawer is also provided with the same bar and locking means as the door. ing. With the drawer closed at the front wall, the opening of the main body is closed, the bar is engaged with the edge of the surrounding wall by operating the moving means, and the locking means is actuated to completely stop the drawer. Locked to.

[0005] Such storages include the following. Fireproof safes A fireproof safe that protects stored items from fire is generally known to prevent heat transfer to the inside of the body by enclosing a fireproof material such as a mixture of cement and water inside the body or door. There is known a technique for improving fire resistance by mixing a mixture of cement and water with pearlite or a foaming agent to generate bubbles. In this fire-resistant safe, the outer frame of the door and the edge of the enclosing wall of the main body open surface in which the outer frame is fitted have a lightning-shaped or step-shaped cross-sectional shape, and the total area of the facing portion between the outer frame of the door and the edge is reduced. A smoke bending structure including a smoke return that protects the stored items by increasing the reach of the flame, heat, smoke, and the like from the outside to the inside of the main body by increasing the size is employed.

As a theft safe for protecting stored items from theft, a hammer using a fireproof material provided with a wire netting, a steel piece, a high-hardness protective plate, or a thick iron plate covering the fireproof material is used. It is designed to withstand vandalism, such as blows by a torch, cutting by a torch, cutting by a cutter, and prying with a crowbar. Further, the locking means has a re-locking structure having a second locking mechanism for automatically fixing the bar when the locking mechanism is broken by an external force (for example, Japanese Utility Model Application Laid-Open No. 59-26164).
Publication No.) is adopted.

[0007] Powerful safes, super-strong safes, and storage archives A strong safe and a super-strong safe having both fire resistance and anti-theft performance are provided with the above-mentioned smoke bending structure and a thick iron plate covering a fire-resistant material, or a fire-resistant safe. There is a so-called secondary storage in which an anti-theft safe is placed inside a safe. As storage archives, there are those that have fireproof performance like fireproof safes and those that do not have fireproof performance.

[0008]

In the above-mentioned fire safe,
By embedding a wire mesh, a billet, a protection plate, or the like in a refractory material, or by changing the material or the number thereof, the resistance to destruction, fusing, cutting, or prying can be changed in the same manner as in the anti-theft safe. Among them, in order to increase the resistance against prying-up, which is the most difficult measure, it is conceivable to provide a plurality of bars and to use a plurality of high-hardness protective plates which are not easily deformed.

However, most of the safes used in offices and homes are usually fire-resistant safes, and even if measures are taken to provide a plurality of bars, the bars are at most 20 m from the main body.
m, the engagement between the main body and the bar can be easily released by significantly deforming the side wall of the main body where the bar is fitted using a long bar. Is released in a short time. In addition, the countermeasure using a plurality of high-hardness protective plates has a problem that the cost is increased and the weight is significantly increased.

In an anti-theft safe, a strong safe, and a super-strong safe, the iron plate has a sufficiently large thickness to have sufficient resistance to prying open, but the thick iron plate increases the weight of the safe. There is a problem that the price is greatly increased as compared with a normal fire safe.
In particular, if the weight increases (about 50 kg or less for a small safe, about 200 to 300 kg for a fireproof safe, about 800 to 1000 kg for an ultra-strong safe), the safe can be placed in a strong place such as a wall or above a beam. Because the installation location is limited (the floor strength of the building according to the Building Standards Law is 180 kg / m ² for houses and hospital rooms, and 230 kg / m2 for classrooms).
(m ² , 300 kg / m ² for offices and department stores). This poses a layout problem, and when it is installed in another place, it is necessary to provide a reinforcing material, which increases the cost.

The present invention solves the above-mentioned problems, and provides a storage box such as a fire-resistant safe, a storage library, etc., which can improve the anti-theft property without increasing the cost and weight, and further improves the anti-theft performance. The purpose of the present invention is to provide a storage box such as an anti-theft safe, a strong safe, and a super strong safe.

In each of the above embodiments, the lock member is formed by a bar 5
Using only one of the moving means 12 through the running plate 14.
Is moved by operating the handle 6,
The lock member and the moving means are not limited to these, and various types can be applied. Hereinafter, modified examples of the lock member and the moving unit will be described.

FIG. 8 shows that three running plates 39 each having a bar 36, 37, 38 are movably mounted near the outer periphery of the turning plate 40, and the shaft 6 of the handle 6 is mounted at the center of the turning plate 40.
is attached, and the handle 6 is rotated clockwise in the figure, so that the bars 36, 37, and 3 having different moving directions are respectively provided.
8 is simultaneously moved to a lock position indicated by a two-dot chain line. Thereby, the door and the main body are engaged in three directions (four directions are also possible), so that the antitheft property can be improved. When a bar that can be moved in four directions is provided, only the bar on the rear side (the side where the door is supported by the hinge) can adopt a fixed type.

FIG. 9 shows a mechanism for simultaneously moving a plurality of bars 41 in the same direction. Each of the bars 41 having the same shape is a running plate 4 movably supported in the left-right direction by two pins 42 planted inside the door and a guide member (not shown).
An eccentric cam 45 fixed to a support shaft 44 rotatably supported inside the door is provided near the running plate 43. The running plate 43 is urged rightward in the drawing by urging means (not shown), and is configured to always contact the circumferential portion of the eccentric cam 45. With this configuration, the support shaft 44 can be formed by a motor or other appropriate means.
By rotating, each bar 41 is moved to a lock position shown by a two-dot chain line in the figure. As a result, the door and the main body are engaged with each other at a plurality of locations in one direction, so that the antitheft property can be improved.

FIG. 10 shows a mechanism for simultaneously moving a plurality of bars 46 in the same direction. In this mechanism, each bar 46 slidably supported by a plurality of slide guides 49 is integrally connected by a connecting plate 47, and the shaft 6 a of the handle 6 is attached to the center of the rotating plate 48 to form one bar. This is a configuration in which the rotation plate 46 and the rotation plate 48 are connected by the operation plate 23, and differs from the mechanism shown in FIG. 9 in that a running plate is not used. By adopting this configuration, a plurality of bars can be moved at the same time without using the running plate, and when the storage box is pry open by the bar, the engagement between the bar and the main body caused by the deformation of the running plate is reduced. 9 can be prevented from being released, and FIG.
The anti-theft property can be improved as compared with the mechanism shown in FIG.

As a method of moving each bar 46, FIG.
As shown in FIG. 1, a method in which an operating plate 23 is brought into contact with an eccentric cam 25 rotatably supported on a support shaft 24 and the eccentric cam 25 is rotated by a motor, and as shown in FIG. 23, a pneumatic or hydraulic cylinder 27 as shown in FIG.
As shown in FIG. 14, levers 29 and 3 rotatably supported by a support shaft 28
0, the method of moving the operation plate 23, the method of winding the wire 31 by the motor 32 as shown in FIG. 15, and the method of moving the rack 33 and the pinion 34 as shown in FIG.
And a motor using a rack and pinion mechanism, and a method using a feed screw mechanism including a feed screw 80 and a screw bush 81 as shown in FIG. These may be provided alone or in parallel.

In the present invention, since it is necessary to increase the amount of movement of the bar as a lock member, of the above-described plurality of methods of moving the bar, a method using an eccentric cam shown in FIG. 11 and a wire shown in FIG. Using a motor and
A method using a rack and pinion mechanism shown in FIG. 16,
A method using a feed screw mechanism shown in FIG. 17 is suitable. In the case where the method using the handle as shown in each of the above embodiments is adopted, it is necessary to increase the turning radius (between the fulcrum and the force point and between the fulcrum and the action point) of the handle. As described above, the first lever 50 rotatably supported by the support shaft 50 a and connected to the operation plate 23.
And a second lever 51 rotatably supported by the support shaft 51a and connected to the first lever 50 and having a handle (not shown), the moving distance of the second lever 51 is reduced. Also, the moving distance of the bar 46 can be increased.

In each of the above-described embodiments, the safe 1 with a single-door opening to the right is shown as a storage. However, the storage is not limited to this, and the storage 53 is a single-door, left-opening, as shown in FIG.
A door 54 as an opening / closing body which is supported by hinges 56, 56 attached to the main body 53 so as to be openable and closable and has a handle 6, a dial lock 7, and a cylinder lock 8;
A safe 52 having a child door 55 as an opening and closing body supported by hinges 57, 57 attached to the main body 53 so as to be openable and closable, or opened and closed by hinges 60, 60 attached to the main body 59 as shown in FIG. Supported and handle 6, dial lock 7, cylinder lock 8
And a left door 63 as an opening and closing body having a handle 6, a dial lock 7, and a cylinder lock 8 while being openably and closably supported by hinges 62, 62 attached to the main body 59. May be used.

When the safe 52 shown in FIG. 19 is employed, the amount of protrusion of the bar from the door 54 is increased as in the above-described embodiments. Alternatively, the child door 55 may be penetrated to form the inside of the main body 53. When the safe 58 shown in FIG. 20 is adopted, the amount of protrusion of the bar from the door 61 is increased as in the above-described embodiments, and the tip position of the bar at the lock position is changed to the door 6.
3 or the inside of the main body 59 through the door 63. Of course, a configuration in which the bar is projected from the door 63 toward the inside of the door 61 may be adopted.

The term "child door" as used herein means that the ratio of the size to the door is not specified, and the door may have a handle, a grip, a knob, a handle, a locking means, etc. on the outside front. However, it has a fixing member for fixing the child door itself to the main body by being fitted or engaged with the main body, and this fixing member is provided with the above-mentioned handle, grip, knob, handle, locking means and the like. It is indispensable that the configuration is not linked. The fixing member cannot be operated from the front side of the child door, and is operated on the side surface or the rear surface of the child door.

Regarding both doors, regardless of the size of the left and right doors, an externally provided handle, locking means, etc., and an operating portion of the fixing member are interlocked. That can be moved.

Due to this difference in construction, the child door does not have an operating mechanism for the fixing member inside (it is small even if it has one).
Since there is no through hole from the outside to the inside on the front surface (hole through which the handle shaft directly connected to the operating mechanism of the fixed member passes)
The handle and the operating part of the fixing member are interlocked, and although the operability is inferior to that of a double door capable of operating the fixing member from the front, the volume occupied by the operating mechanism of the fixing member is small, and fire resistance is reduced. There is an advantage that the fire resistance is improved by increasing the storage amount of the material, and the antitheft property is improved by improving the cross-sectional performance. In addition, a safe with a child door has a larger width of an engagement portion between the door and the main body (a width from a gap between the door and the main body to an outer wall of the main body) as compared with a single-open safe, so that the When opening the door by inserting the tip of a crowbar into the gap, the resistance increases, and the anti-theft property is higher than that of a single-open safe.

Further, instead of the safe 1, safes 76 and 78 shown in FIGS. 21 and 22 may be used. Safe 76 is Safe 1
Is different only in that, instead of the main body 2, a main body 77 in which the width W1 of the front end face of the main body on the side where the bar 5 is engaged is formed larger than the thickness of the side wall, and other configurations are the same. Are identical. The safe 78 is different from the safe 1 in that the width W1 of the front end face of the main body on the side where the bar 5 is engaged and the width W2 of the front end face of the main body on the side where the door 3 is supported by the hinges 4 are replaced with the side walls. The only difference is that a main body 79 formed to be larger than the thickness is used, and other configurations are the same.

With these configurations, the width W1 of the safe 76 is sufficiently large, so that when the tip of the bar is inserted between the door 3 and the main body 77 and the door 3 is pryed open, the resistance is increased and the antitheft property is improved. In addition, since the widths W1 and W2 of the safe 78 are sufficiently large, the main body 79 is not easily deformed in the event of a fire, and the fire resistance can be improved in addition to the effect of the safe 76.

Further, as shown in FIG. 23, the present invention may be applied to a storage library as a storage. In the figure, the storage library 64 is mainly composed of a library main body 65 as a main body and three drawers 66 as an opening / closing body.
Each drawer 66 is independently provided so as to be freely drawn out. The drawer 66 has a handle 67, a bar 68 as a lock member, and a lock 69 for moving the bar 68 between a locked position and a non-locked position.
Are provided respectively. The library main body 65 includes each drawer 6
6 is provided so as to be able to be pulled out freely, and each open portion 65A is constituted by a front surface of the space. Each opening 6
The fitting portion between 5A and each drawer 66 employs the same smoke bending structure as in the above embodiments. The amount of protrusion of the bar 68 from the drawer 66 is desirably set stepwise according to the diameter of the bar 68 and the thickness of the side wall of the main body 65 as in the above-described embodiments. As the drawer 66, a drawer filled with a refractory material may be used. The connection between the bar 68 and the lock 69 adopts a configuration as shown in FIGS. 9, 10, and 11.

In this modification, each drawer 66 is provided with a lock 69 so that each drawer 66 can be locked individually. However, only the uppermost drawer 66 is provided with a lock 69 and locked. A configuration in which all the drawers 66 are locked may be adopted. In this way, a configuration in which the bar 68 is moved by the lock 69, that is, a configuration that does not use the moving means may be adopted in a small safe.

In each of the above embodiments and modified examples,
6, 37, 38, 41, 46, 68 as diameters 12 to 3
An example using a round bar of about 5 mm was shown, but as a bar, an elliptical round bar, a square or rectangular or polygonal square bar, a round pipe, a square pipe, a plate-like thing such as flat steel, A telescopic device such as an automobile antenna may be used.

Square or polygonal square bar as a bar,
When a round pipe, a square pipe, or the like is used, the protrusion of the bar is the same as that of the round bar shown in Table 1. When an elliptical round bar, a rectangular square bar, a flat bar made of flat steel or the like, or an elliptical pipe is used as a bar, the protrusion of the bar is determined by its short axis length or short side length. (Thickness). Table 2
Shows the relationship between the short side length (short axis length and thickness) of the bar and the amount of protrusion.

[0049]

[Table 2]

As a bar, at least the tip is formed of a steel material such as ceramic or SUS304 or the like, which is formed of a material having a lower thermal conductivity than mild steel, or is exploded with SUS304, or at least the tip is ceramic, SUS304, or a lock. Use of wool, concrete, chrome plating, enamel, or a material covered with a material having a lower thermal conductivity than steel, such as mild steel, such as a cover 74 filled with a low melting point member such as paraffin as shown in FIG. Thereby, fire resistance can be improved. The member to be packed in the cover 74 may be any material other than paraffin, such as wood (preferably paulownia), chipboard, wood bristle member, and ash, as long as the material has a lower thermal conductivity than a steel material such as mild steel. Further, the above-described coating may be applied only to at least the end face of the tip of the bar.

As a method for opposing the prying with a crowbar, a brittle material is used as the refractory material to be filled in the side wall of the main body, or the thickness of the iron plate of the main body covering the refractory material is reduced to weaken the waist of the main body side wall. Alternatively, a method of weakening the effect of the bar by making the fulcrum easily collapse when the bar is pryed open may be adopted.

In each of the above embodiments and modifications, the moving mechanism of the lock member is provided on the inner side of the storage rather than the refractory material of the door. You may employ | adopt the structure arrange | positioned outside the storage.

It is possible to collectively check the usage status of each storage, the presence or absence of a fire, and the like in predetermined places such as a security room, an owner room, and a management room. Along with this, it is also possible to adopt a system in which the locking means on the main body cannot be unlocked unless the locking is performed on the monitor side.

Further, as an alarm means for the storage, the opening / closing body of the storage is attempted to be opened or approached after operation preparation (after the dial is turned or locked (including the electronic lock), the preparation state is automatically set). The alarm means is activated when it is touched, the one that responds to shock, sound or voice, the one that is activated when the main body is tilted, the human body detection (mat switch, infrared ray, far infrared ray, electromagnetic wave, ultrasonic wave, beam switch (light sensor) ), Mechanical switches, etc.),
Those which react when contacted (by static electricity) are exemplified. Warning methods include the usual police calls, voice alerts (such as "Drobo"), and displays (lights, letters,
Mechanical display (for example, the board pops out), lighting of the room is turned on all at once, doors or shutters (convenience stores, supermarkets, department stores, pachinko parlors, financial institutions, etc.) open all at once and open to the outside Alarms (at night), doors or shutters are completely closed to lock the pirates (daytime or night), or foreign objects (such as ghost dolls) fall or fall from the ceiling to surprise the pirates. Is mentioned.

In each of the above-described embodiments and modifications, the storages include a single-door right-open safe, a single-door left-open safe, a safe with a child door, a double-door safe, and a storage library. The present invention may be applied to a secondary storage in which another safe is stored inside the storage, a storage having a sliding door, or the like. For secondary storage, such as floppy disks, magnetic tapes, optical disks, valuables, cultural assets, etc., those that keep the temperature and humidity inside the warehouse to a certain value even if the temperature and humidity outside the warehouse rise. Also, there is a fire-resistant safe in which an anti-theft safe is stored.

In each of the above embodiments and modified examples, the inside of the main body or the door is filled only with the refractory material made of a mixture of cement and water.
As shown in (1), a high-strength protective plate 70 made of reinforced concrete, manganese steel, stainless steel, molybdenum steel, special steel, wire mesh, expanded metal, or the like mixed with carbon or glass fiber may be embedded. Although this increases the weight, the anti-theft property is greatly improved.

According to the first aspect of the present invention, the locking member is formed on the opening / closing body side even when the opening and closing body is to be opened by inserting the tip of a bur into the gap between the main body and the opening / closing body from the outside of the storage. Since at least one of the formed ridge and the ridge formed on the main body side penetrates, the engagement between the main body and the opening / closing body is not easily disengaged, and the antitheft property can be further improved. it can.

According to the second and third aspects of the present invention,
Since at least the distal end of the lock member is a low thermal conductivity member, fire resistance can be improved.

According to the fourth aspect of the invention, even if the opening of the opening / closing body is attempted by inserting the tip of a crowbar into the gap between the main body and the opening / closing body, the locking member acts as a resistance in the direction in which the bar is opened. It becomes difficult, and the anti-theft property can be further improved.
