Description

  The present invention relates to a fixture in which a locking means is provided on a door, such as a safe. It should be noted that the fixtures include structures that are part of a building, such as a safe room and a dangerous goods storage room.

  Conventionally, a handle that can be rotated up and down is provided on the front surface of a horizontally-rotating door in a safe. On the back side (or inside) of the door, there is a lock rod that moves in and out on the outer peripheral side of the door in conjunction with the vertical rotation of the handle, while a lock rod is provided on the inner peripheral side of the safe body. An engagement hole for engaging and disengaging is formed.

In this case, opening and closing of the door is prevented or permitted by engaging and disengaging the lock rod with respect to the engagement hole of the safe body by the operation of turning the handle up and down. Then, in a state where the lock rod is engaged with the engagement hole of the safe body, the door is locked by preventing the lock rod from being immersed (retracted) by the locking means. As the locking means, a combination of a dial lock and a cylinder lock, or an electronic lock that is unlocked by operating an input unit provided on the front surface of the door is employed.

It is attached to the front face of the door and can be moved in the opening and closing direction of the door, and the handle member and the locking means convert the turning movement of the handle member into the retracting movement of the locking means. It has the basic configuration of being linked and linked via a mechanical linkage mechanism .

Furthermore, the invention according to claim 1 is the above-described basic configuration, wherein the mechanical interlocking mechanism includes a slide plate that is slidable along the back surface of the door, and a rotation that is rotatable about a rotation axis protruding from the back surface of the door. And the slide plate and the rotary disc are configured to rotate the rotary disc around the rotation axis by the sliding movement of the slide plate in conjunction with the turning operation of the handle member. It is said that it is related to move up and down.

According to a second aspect of the present invention, in the lockable fixture according to the first aspect, the handle member includes a trigger body that can be horizontally rotated toward the opening and closing direction of the door, and a grip that covers a front side of the trigger body. And the grip body is attached to the front surface of the door so that the grip body can be gripped by hand together with the trigger body.

According to a third aspect of the present invention, in the lockable fixture according to the second aspect , the trigger body penetrates the door in the thickness direction, and a gripping arm portion exposed in a space between the grip body and the door. The interlocking arm portion has a substantially L shape in plan view, and the distal end portion of the interlocking arm portion in the trigger body is inserted into a square hole formed in the longitudinal middle portion of the slide plate. It is that.

  According to the present invention, the handle member is attached to the front surface of the door in a form extending horizontally and horizontally in a front view, and can be moved in the opening and closing direction of the door. The handle member and the locking means The handle member is interlocked and connected via a mechanical interlocking mechanism that converts the pivoting motion of the handle member into the retracting motion of the locking means.

For this reason, when opening the door, after unlocking the locking means, the handle means is grasped and the door is pulled forward (in the opening direction). The door can be opened in an immersive state. Therefore, people are able to easily and smoothly line the opening operation of the door to Ukoto, it is to become a user-friendly tablet with furniture of any kind from the point of view of universal design.

Further, according to the present invention , the mechanical interlocking mechanism includes a slide plate that is slidable along the back surface of the door, and a turntable that is rotatable around a rotation axis that protrudes from the back surface of the door. The slide plate and the turntable are related so that the slide turn of the slide plate in conjunction with the turning movement of the handle member causes the turntable to rotate about the rotation axis to move the locking means in and out. Therefore, the door can be opened by a very natural operation of grasping the handle member and pulling the door toward the front, and the door can be opened and closed with a small number of parts such as the slide plate and the rotating plate. There is an effect that the rotation of the handle member along the direction can be transmitted to the lock means efficiently and smoothly.

According to the invention of claim 2, the handle member includes a trigger body that can be horizontally rotated in the opening and closing direction of the door, and a grip body that covers a front side of the trigger body, Since the trigger body is attached to the front surface of the door so that it can be grasped by hand, the operation force for moving the trigger body is concentrated on the vicinity of the rotation fulcrum. Can be prevented. For this reason, smooth rotation of the trigger body can be secured to prevent twisting of the trigger body, and as a result, the door can be opened and closed smoothly.

According to a third aspect of the present invention, the trigger body includes a grip arm portion exposed in a space between the grip body and the door, and an interlocking arm portion penetrating the door in the thickness direction. Since the tip of the interlocking arm portion of the trigger body is inserted into a square hole formed in the longitudinal middle portion of the slide plate, the shape of the slide plate is aligned with the door opening / closing direction. There is an effect that the structure for converting the turning operation of the handle member into the sliding movement of the slide plate along the rear surface of the door is extremely simple.

  Hereinafter, an embodiment in which the present invention is applied to a safe which is an example of a lockable fixture will be described with reference to the drawings (FIGS. 1 to 15).

A safe 1 as an example of a locked fixture includes a substantially box-shaped storage body 2 having an open front surface, and a horizontally-rotating door 3 that closes the front opening of the storage body 2. The housing body 2 and the door 3 are made of a metal plate frame filled with a conventionally known material (for example, concrete) having anti-theft and fire resistance as an inner wall. The door 3 is configured to be horizontally rotatable (openable and closable) via a hinge 4 provided on one lateral side. In the following description, the side surface with the door 3 in the safe 1 is referred to as the front surface, and the front, rear, left and right are expressed on the basis thereof (therefore, the left and right in the front view are reversed). Further, “clockwise direction” and “counterclockwise direction” relating to the rotation direction are abbreviated as “clockwise direction” and “counterclockwise direction”, respectively.

  A handle member 5 for opening / closing operation is attached to a position near the free end of the front surface of the door 3. The handle member 5 is formed in a form extending horizontally and horizontally in a front view. On the side of the front side of the door 3 on the lateral side of the handle member 5 (on the left side, which is the hinge 4 side in the embodiment), a substantially box-shaped operation housing 6 protruding forward is provided with a plurality of bolts 7 ( 4 to 5). On the front surface of the operation housing 6, a dial knob 9 which is an operation portion of a dial lock 8 as a locking means is exposed. In other words, the safe 1 of the first embodiment is of the dial lock type. A key hole 11 of the cylinder lock 10 is exposed below the handle member 5 in the front surface of the door 3.

  As shown in FIG. 2 (a), inside the door 3, the above-described dial lock 8 and cylinder lock 10, a plurality of lock rods 12 as locking means that can move in and out on the outer peripheral side of the door 3, and a lock A mechanical interlocking mechanism 13 that associates the movement of the ridge 12 with the operation of the handle member 5 is disposed. An inner cover body (not shown) made of a metal plate is provided on the back side of the door 3, and the components inside the door 3 (the lock interlock 12 and the mechanical interlocking mechanism 13) are on the back side of the door 3. It is also invisible (hidden). Although not shown in detail, the storage body 2 is provided with a plurality of shelves and drawers for storing articles such as valuables.

(1-2). Detailed Structure of Handle Member and Operation Housing Next, a detailed structure of the handle member 5 and the operation housing 6 will be described with reference to FIGS.

  The handle member 5 includes a trigger body 15 that can be moved in the opening / closing direction of the door 3 and a grip body 16 that covers the front side of the trigger body 15. The grip body 16 has a substantially U-shaped configuration in plan view by a horizontally long handle portion 17 and a pair of leg portions 18 and 19 protruding in the same direction from the left and right end portions of the handle portion 17. The left and right leg portions 18 and 19 are fastened to the front surface of the door 3 with bolts and nuts. A space S surrounded by the grip body 16 and the front surface of the door 3 is sized to allow fingers to be inserted. A horizontally long decorative panel 20 is attached to the front surface side of the handle portion 17. A concave groove 21 is formed on the inner peripheral side of the grip body 16 (the side facing the gap S) from the left leg 18 to the right leg 19 through the handle 17 (see FIG. 5).

  The trigger body 15 is formed in a substantially L-shaped form in plan view by the gripping arm portion 22 exposed in the space S between the grip body 16 and the door 3 and the interlocking arm portion 23 penetrating the door 3 in the thickness direction. Is formed. Thus, since the grip arm portion 22 of the trigger body 15 is exposed in the space S between the grip body 16 and the door 3, fingers are inserted into the space S, and the grip arm portion 22 of the trigger body 15 is inserted. And the grip portion 17 of the grip body 16 can be gripped together. A corner portion of the gripping arm portion 22 and the interlocking arm portion 23 is pivotally attached to a position on the left leg portion 18 side of the recessed groove 21 of the grip body 16 so as to be horizontally rotatable by a vertical pivot shaft 24. ing.

  Although details will be described later, in the first embodiment, when the gripping arm portion 22 of the trigger body 15 is horizontally rotated around the pivot shaft 24 (toward the opening and closing direction of the door 3), the interlocking arm portion 23 is moved to the gripping arm portion. 22 is rotated integrally around the pivot shaft 24, and the slide plate 34 disposed inside the door 3 is moved in the left-right direction by the pressing action of the distal end portion thereof (see the directions of arrows SL and SR in FIG. 2A). It is configured to slide.

As can be seen from FIGS. 1 and 4 to 6, the operation housing 6 disposed on the left side of the handle member 5 includes a substantially box-shaped base 25 having an upper surface and a front surface opened, and an upper surface of the base 25. The lid cover body 26 covers up to the front surface, and the back portion of the base 25 is fastened to the front surface of the door 3 with bolts 7. The lid cover body 26 is detachably attached to the upper surface and the front surface side of the base 25.

  Most of the front surface of the lid cover body 26 is formed on an inclined surface 27 inclined obliquely downward toward the front of the door 3. In other words, most of the front surface of the lid cover body 26 is an inclined surface 27 that is inclined so that the front-rear length of the operation housing 6 increases as it approaches the lower end from the upper end in a side view. The lower part of the front surface of the lid cover body 26 is a curved surface 28 that protrudes forward. There is no step at the joint between the inclined surface 27 and the curved surface 28, and they have a smooth continuous appearance. In the first embodiment, the inclination angle θ of the inclined surface 27 with respect to the horizontal is set to about 55 ° (see FIG. 6).

  On the inclined surface 27 of the lid cover body 26, a dial knob 9 which is an operation portion of the dial lock 8 as a locking means is disposed so as to be exposed forward. Therefore, the dial shaft 29 protruding rearward from the dial knob 9 extends obliquely downward and rearward perpendicular to the inclined surface 27 and penetrates the operation housing 6 and the door 3.

  By the way, in the conventional safe, the operation part (a dial knob, a numeric keypad type input part, etc.) of the locking means is directly attached to the vertical front surface of the door. For this reason, depending on the size of the safe, when the user operates the operation unit, it is difficult to see the operation unit while standing, and the user must squat to face the operation unit.

  In this regard, in the embodiment, since the dial knob 9 of the dial lock 8 is disposed on the inclined surface 27 inclined obliquely forward and downward in the lid cover body 26, when the user operates the dial knob 9, If you look down or bend forward, you can face the dial knob 9 without crouching. Therefore, the dial knob 9 is easy to see and its operability is improved.

  Further, as described above, since the dial knob 9 is disposed on the inclined surface 27 inclined obliquely downward and forward in the lid cover body 26, the dial shaft 29 extends obliquely downward and rearward perpendicular to the inclined surface 27. become. For this reason, even if the bandits strike the dial knob 9 horizontally with a hammer or the like when breaking the safe, the dial shaft 29 only acts on the dial striking force in the diagonally downward direction of the horizontal striking force. There is also an advantage that it is difficult to extract 29.

  A step portion 30 (see FIG. 3) corresponding to the left leg portion 18 of the grip body 16 is formed as a recess in the lower left corner portion of the operation housing 6 (the lid cover body 26 and the base 25). In a state where the operation housing 6 is attached to the front surface of the door 3, the step portion 30 of the operation housing 6 covers the left leg portion 18 of the grip body 16 from above. In other words, the right side portion of the operation housing 6 overlaps (overlaps) the left leg portion 18 of the grip body 16 in plan view. The left end portion of the decorative plate 20 in the grip body 16 is in a state of projecting to the lower front side of the lid cover body 26 in a front view.

  As shown in FIGS. 1 and 6, the front surface of the decorative plate 20 in the grip body 16 is formed on a curved surface 31 that protrudes forward, similarly to the lower front portion of the lid cover body 26. In addition, the inclined surface 27 and the curved surface 28 of the lid cover body 26 and the curved surface 31 of the decorative plate 20 are separate from each other, but as if they are the same curved surface that is continuous with each other. It has a certain appearance.

  With this configuration, the right side portion of the operation casing 6 overlaps (overlaps) the left leg portion 18 of the grip body 16 in a plan view, so that the length of the handle member 5 in the horizontal direction (hand The handle member 5 and the operation housing 6 can be arranged together in a compact manner after sufficiently securing the length of the portion gripped by the handle.

  In addition, since the inclined surface 27 and the curved surface 28 of the lid cover body 26 and the curved surface 31 of the decorative plate 20 are formed to have an integrated appearance as if they are the same curved surface that is continuous with each other, As a whole combination of the handle member 5 and the operation housing 6, there is no sense of incongruity in design, and the aesthetic feeling is also excellent.

(1-3). Next, a structure related to unlocking in the door 3 will be described with reference to FIGS. 2 and 7.

  The mechanical interlocking mechanism 13 disposed inside the door 3 is for converting the turning operation of the handle member 5 into the movement of the lock rods 12 and protrudes backward from the inner back surface of the door 3. A rotating disk 33 is provided rotatably supported on the rotating shaft 32. A slide plate 34 extending horizontally in the horizontal direction and a plurality of lock rods 12 as locking means are knotted to the rotary plate 33 by pins. In the following description and drawings, for convenience, the first lock rod 12 extending toward the upper end surface of the door 3 is denoted by a, the second lock rod 12 extending toward the free end of the door 3 is denoted by b, and the door 3 The third lock rod 12 that extends toward the lower end surface of the same is denoted by reference symbol c.

  The slide plate 34 and the lock rods 12 are supported so as to be slidable along the longitudinal direction by guide means such as pins. A horizontally long square hole 35 is formed in the longitudinal middle portion of the slide plate 34. The distal end portion of the interlocking arm portion 23 that penetrates the door 3 in the thickness direction of the trigger body 15 is inserted into the square hole 35.

  In the first embodiment, the third lock rod 12c is provided at a lower end surface of the door 3 by a tension spring 37 mounted between the longitudinal middle portion thereof and the mounting shaft 36 protruding from the inner back surface of the door 3. It is always urged in a direction that protrudes downward. For this reason, when the trigger body 15 is not operated, the elastic biasing force of the tension spring 37 acts in a direction in which each lock rod 12 protrudes from the outer peripheral surface of the door 3.

In a state where the dial lock 8 and the cylinder lock 10 are unlocked and the door 3 is closed, the gripping arm portion 22 of the trigger body 15 is rotated counterclockwise around the axis of the pivot shaft 24 in FIG. 4 and FIG. 3 (opening direction 3) (see the two-dot chain line state in FIG. 5), the tip of the interlocking arm 23 pushes the slide plate 34 in the direction of the arrow SR in FIG. Then, due to the action of the slide plate 34, the turntable 33 rotates in the clockwise direction around the axis of the rotary shaft 32 (see arrow TR direction) in FIG. Immerse (retreat) all at once from the outer periphery. As a result, the engagement holes (not shown) formed in the inner peripheral surface of the housing main body 2 and the lock rods 12 are disengaged, so that the door 3 is opened and closed (free state).

  Thereafter, when the door 3 is closed, the distal end side of the third lock rod 12c protrudes from the outer peripheral surface of the door 3 by the elastic restoring force of the tension spring 37, and enters the engagement hole (not shown) of the housing body 2. Engage and enter a protruding state (locked state) that prevents the door 3 from opening and closing. Therefore, the turntable 33 rotates in the counterclockwise direction (see the arrow TL direction) around the rotation shaft 32 in FIG. 2A, and the tip ends of the other lock rods 12a and 12b also protrude from the outer peripheral surface of the door 3. Then, it engages with an engagement hole (not shown) of the housing main body 2 and enters a protruding state (locked state) that prevents the door 3 from opening and closing.

  Further, as the turntable 33 rotates in the direction of arrow TL, the slide plate 34 slides in the direction of arrow SL in FIG. 2A, and the distal end portion of the interlocking arm portion 23 also moves together with the slide plate 34 in FIG. Move in the direction of arrow SL. As a result, the gripping arm portion 22 of the trigger body 15 rotates horizontally in the clockwise direction around the pivot shaft 24 (the closing direction of the door 3) in FIGS. 4 and 5, and the solid line in FIGS. It returns to the original state shown.

  As described above, when the trigger body 15 is not operated, the elastic biasing force of the tension spring 37 acts in the direction in which each lock rod 12 protrudes from the outer peripheral surface of the door 3. In this regard, in the first embodiment, a lock rod storage mechanism 60 similar to that disclosed in Japanese Patent Laid-Open No. 10-184118 is employed. That is, as shown in FIG. 2B, a leaf spring regulating piece 61 is arranged in a suspended state in which only the upper end side is bolted in the vicinity of the third lock rod 12c on the inner and rear surfaces of the door 3. In the state where the door 3 is opened, the end piece 63 of the third lock rod 12c in the immersive state is brought into contact with the engaging piece 62 projecting on the back side of the restricting piece 61 (engagement engagement). ), The lock rods 12 are held so as not to protrude until the door 3 is closed, and the immersion state (free state) is maintained.

  Further, in this configuration, if the door 3 is pushed and closed to the back side (the closing direction of the door 3), the lower end opening edge of the housing body 2 presses the front end of the regulating piece 61 forward. The hooking engagement between the locking piece 62 and the end face 63 of the third lock rod 12c is released. As a result, all the lock rods 12 are held in a protruding state (locked state) protruding from the outer peripheral surface of the door 3 by the elastic biasing force of the tension spring 37, and as a result, the grip arm portion of the trigger body 15. 22 is held in the horizontal posture shown in FIGS.

  A mounting bracket 38 is fastened with bolts so as to straddle the left half of the slide plate 34 (cover from behind) on the inner and rear surfaces of the door 3 in the vicinity of the turntable 33 (see FIG. 7). The lower half of the mounting bracket 38 is an inclined surface 39 that is inclined obliquely downward toward the inner back surface of the door 3. Although not shown in detail, the inclined surface 39 of the mounting bracket 38 and the inclined surface 27 of the lid cover body 26 in the operation housing 6 are set in a parallel relationship.

  A dial lock 8 as a locking means is attached to the inclined surface 39 of the mounting bracket 38. A dial shaft 29 extending obliquely downward rearward from the dial knob 9 passes through the mounting bracket 38 and is connected to the dial lock 8. The dial lock 8 includes a dial housing 40 that moves forward and backward toward the turntable 33 by rotating the dial knob 9. On the other hand, when each lock rod 12 is in the protruding state (locked state), the rotation surface of the rotating plate 33 is prevented from rotating in the direction of the arrow TR by contacting the dial housing 40 in the protruding state. A locking protrusion 41 protrudes backward.

  When the lock rod 12 is protruded after the door 3 is closed and the dial lock 8 is operated to lock in this protruding state (locked state), the dial housing 40 moves forward and contacts the lock protrusion 41 of the turntable 33. The rotation plate 33 is prevented from rotating in the arrow TR direction. As a result, the turntable 33 and thus the lock rods 12 are held in the protruding state (locked state), and the door 3 cannot be opened.

  A cylinder lock 10 is attached below the rotary disk 33 and in the vicinity of the third lock rod 12c on the inner and rear surfaces of the door 5. The cylinder lock 10 includes a cylinder housing 42 that moves forward and backward toward the third lock rod 12c by rotating a key (not shown). On the other hand, a notch 43 that engages and disengages the cylinder housing 42 when the third lock rod 12c is in the protruding state (locked state) is formed in the longitudinal middle portion of the third lock rod 12c.

  When the lock rod 12 is protruded after the door 3 is closed and the cylinder lock 10 is operated to lock in the protruding state (locked state), the cylinder housing 42 moves forward to the notch 43 of the third lock rod 12c. Engage and the third lock rod 12c becomes non-slidable. As a result, the first and second lock rods 12a and 12b are also held in the protruding state (locked state), and the door 3 cannot be opened.

  In the above configuration, when opening the door 3, after unlocking the dial lock 8 and the cylinder lock 10, a finger is inserted into the space S surrounded by the grip body 16 of the handle member 5 and the front surface of the door 3, By grasping the grip arm portion 22 of the trigger body 15 and the handle portion 17 of the grip body 16 together, the tips of the lock rods 12 are simultaneously immersed (retracted) from the outer peripheral surface of the door 3, and the lock rods 12 are immersed. Set to the state (free state). And what is necessary is just to pull to the near side (opening direction of the door 3), holding the handle member 5. FIG.

That is, since the door 3 can be opened by one very natural operation of holding the handle member 5 and pulling the door 3 forward (in the opening direction of the door 3), a person can easily and smoothly open the door 3, From the viewpoint of universal design, the safe 1 is user-friendly.

  In this case, the slide plate 34 and the turntable 33 constituting the mechanical interlocking mechanism 13 are rotated around the rotation shaft 32 by the slide movement of the slide plate 34 interlocked with the turning operation of the handle member 5. Since each of the lock rods 12 is related to move in and out, the door 3 can be opened by a very natural operation of grasping the handle member 5 and pulling the door 3 forward. With the small number of components of 33, the turning operation of the handle member 5 along the opening / closing direction of the door 3 can be transmitted to each lock rod 12 efficiently and smoothly.

  Further, in the first embodiment, the end face portion 63 of the third lock rod 12c in the immersive state is brought into contact with the engaging piece portion 62 of the regulating piece 61 constituting the lock rod storage mechanism 60 (hook engagement). Therefore, even if the hand is released from the handle member 5 after the door 3 is opened, the lock rods 12 can be held so as not to protrude, and the subsequent door 3 can be smoothly closed.

Moreover, Squeezing the door 3 on the back side (closing direction of the door 3), maintained by the locking rod receiving mechanism 60 of the immersive state of the lock rod 12 is released, an elastic urging force of the tension spring 37, each The front ends of the lock rods 12 protrude from the outer peripheral surface of the door 3 all at once, and each lock rod 12 automatically enters the protruding state (locked state). Thereafter, the dial lock 8 and the cylinder lock 10 may be locked. Therefore, when the door 3 is closed, it is only necessary to push the door 3 back (the door 3 closing direction), and the door 3 can be closed very easily.

  In particular, in the first embodiment, in order to place each lock rod 12 in an immersive state, the grip arm portion 22 of the trigger body 15 and the handle portion 17 of the grip body 16 are held together. Thus, it is possible to prevent the operation force for rotating the lens around the pivot shaft 24 from acting intensively in the vicinity of the pivot shaft 24. For this reason, smooth rotation of the trigger body 15 can be secured, and twisting of the trigger body 15 can be prevented from occurring, and as a result, the door 3 can be opened and closed smoothly.

  In addition, since a configuration is adopted in which the tip end portion of the interlocking arm portion 23 of the trigger body 15 is inserted into the square hole 35 formed in the longitudinal middle portion of the slide plate 34, the handle member along the opening / closing direction of the door 3 is adopted. Thus, the structure for converting the rotation operation 5 into the sliding movement of the slide plate 34 along the back surface of the door 3 is extremely simple.

(2). Second Embodiment FIGS. 8 and 9 show a second embodiment of the present invention. 8A is an enlarged view of a main part showing a second embodiment of the operation unit provided in the operation casing, FIG. 8B is an enlarged view of a main part showing another example of the second embodiment, and FIG. It is an expanded side view of the operation housing | casing in 2nd Embodiment.

  In the second embodiment shown in FIGS. 8A and 9, on the inclined surface 27 of the lid cover body 26, a numeric keypad type input unit 44 that is an operation unit of an electronic lock (not shown) as a locking unit, It differs from that of the first embodiment in that a fingerprint recognition unit 46 of the fingerprint collation device 45 and a liquid crystal panel unit 47 capable of displaying operation commands are arranged. In this case, the electronic lock is an alternative to the dial lock 8 of the first embodiment. Although details are omitted, when an input according to a preset fingerprint pattern and password is performed, a housing that can be moved forward and backward toward the turntable 33 moves back and forth by the drive of the motor. The rotation, and consequently the sliding movement of each lock rod 12 is allowed. Other configurations are generally the same as those in the first embodiment.

  Since the operation casing 6 of the second embodiment is formed in a form in which the front-rear length becomes longer as approaching the lower end from the upper end in a side view, there is a space in the lower portion of the base 25. In this space, a battery accommodating portion 49 with a lid 50 for accommodating a plurality of dry batteries 48 for supplying driving power to the motor is formed (see FIG. 9). The lid 50 is provided on the side surface (the left side surface in the embodiment) opposite to the step portion 30 of the base 25 so as to be opened and closed. The dry battery 48 group is inserted into the battery accommodating portion 49 in a state of being mounted on the dry battery holder. A main body portion of the fingerprint collation device 45 is built in the base 25 above the battery housing portion 49.

  If comprised in this way, since the main body part of the dry battery 48 and the fingerprint collation device 45 can be accommodated in the operation housing | casing 6, and it is not necessary to form the hole for accommodating these in the door 3, the rigidity of the door 3 is made. Can maintain a high state. Further, since the dry battery 48 is used as a power supply source, there is an advantage that the safe 1 can be used even in a place where there is no commercial power outlet or the like, and it is easy to handle. In addition, since the battery housing portion 49 is provided outside the housing body 2 and the door 3, it is not necessary to open and close the door 3 when replacing the dry battery 48. This point also contributes to the improvement of theft protection.

  Note that, as another example of the second embodiment shown in FIG. 8B, only the numeric keypad type input unit 51 may be arranged on the inclined surface 27 of the lid cover body 26 as an electronic lock operation unit. Good. In this case, when input according to a preset password is performed from the input unit 51, a housing that can move forward and backward toward the rotating disk 33 moves back and forth by driving the motor, and the rotating disk 33 rotates. As a result, sliding movement of each lock rod 12 is allowed.

Third Embodiment FIGS. 10 to 13 show a third embodiment of the present invention. 10A is a rear view of the door in the locked state in the third embodiment, FIG. 10B is a back view of the door in the free state, FIG. 11 is an enlarged plan sectional view of the handle member, and FIG. (A) is an enlarged rear view of the lock rod storage mechanism in the open state, (b) is an enlarged rear view of the lock rod storage mechanism in the closed state, and (a) in FIG. The top sectional view of a storing mechanism, (b) is a top sectional view of a lock rod storing mechanism in a closed state. In 3rd Embodiment, the structure regarding the unlocking | locking in the door 3 is a little different from the thing of 1st Embodiment. Other configurations are generally the same as those in the first embodiment.

Hereinafter , differences from the first embodiment will be described. 10, the illustration of the inner cover body 14 is omitted as in FIG. 2, and in FIG. 12, the inner cover body 14 is indicated by a two-dot chain line to disclose the internal structure. Inside the door 3 in the third embodiment, there are a dial lock 8 and a cylinder lock 10, a plurality of lock rods 72 as locking means that can move in and out on the outer peripheral side of the door 3, A mechanical interlocking mechanism 73 that associates the operation of the handle member 5 is disposed.

  Similarly to the first embodiment, the mechanical interlocking mechanism 73 of the third embodiment is also for converting the turning operation of the handle member 5 into the moving movements of the plurality of lock rods 72. , And two rotating disks 75a and 75b rotatably supported by rotating shafts 74a and 74b that protrude rearward from the rear surface of the door 3.

  The slide plate 34 is knotted by a pin on one end side of the first rotary disk 75a positioned below the slide plate 34 with the rotation shaft 74a interposed therebetween. A first lock rod 72a extending horizontally in the horizontal direction toward the free end of the door 3 is knotted by a pin on the other end side of the first rotating disk 75a with the rotation shaft 74a interposed therebetween. The first lock rod 72a is supported by a guide means such as a pin so as to be slidable in the left-right longitudinal direction.

  Further, the first lock rod 72a is knotted by a pin to a second rotary disk 75b positioned below the first lock rod 72a. In addition to the first lock rod 72a, the second rotary plate 75b includes a second lock rod 72b that extends across the first lock rod 72a and the slide plate 34 toward the upper end surface of the door 3, and a lower end surface of the door 3. A third lock rod 72c extending toward the top is knotted by a pin.

  Also in the third embodiment, the third lock rod 72c is attached to the bottom of the door 3 by a tension spring 77 mounted between the middle part in the longitudinal direction and the mounting shaft 76 protruding from the inner and rear surfaces of the door 3. It is always urged in a direction protruding downward from the end face. For this reason, when the trigger body 15 is not operated, the elastic biasing force of the tension spring 77 acts in a direction in which the lock rods 72 protrude from the outer peripheral surface of the door 3.

  In a state where the dial lock 8 and the cylinder lock 10 are unlocked and the door 3 is closed, the gripping arm portion 22 of the trigger body 15 is counterclockwise around the pivot shaft 24 (the opening direction of the door 3) in FIG. When horizontally rotated (refer to the one-dot chain line state in FIG. 11), the distal end portion of the interlocking arm portion 23 presses the slide plate 34 in the direction of the arrow SR in FIG.

  Then, due to the action of the slide plate 34, the first rotating disk 75a rotates in the clockwise direction around the rotating shaft 74a (see the arrow TR1 direction) in FIG. 10A, and the front end side of the first lock rod 72a is moved to the door 3. Immerse (retreat) from the outer peripheral surface of. As the first lock rod 72a is immersed, the second rotating disk 75b rotates counterclockwise around the rotation shaft 74b (see the direction of the arrow TL2) in FIG. The front end side of the 3 lock rod 72c is immersed from the outer peripheral surface of the door 3. As a result, the engagement hole (not shown) formed in the inner peripheral surface of the housing main body 2 is disengaged from each lock rod 72, and the door 3 is in an immersive state (free state) that allows opening and closing ( (Refer FIG.10 (b)).

  Thereafter, when the door 3 is closed, the distal end side of the third lock rod 72c protrudes from the outer peripheral surface of the door 3 by the elastic restoring force of the tension spring 77, and enters the engagement hole (not shown) of the housing body 2. Engage and enter a protruding state (locked state) that prevents the door 3 from opening and closing. Further, as the third lock rod 72c protrudes, the second turntable 75b rotates clockwise around the rotation shaft 74b (see the direction of arrow TR2) in FIG. 10B, and the other lock rods 72a and 72b The front end side is projected from the outer peripheral surface of the door 3 and is engaged with an engagement hole (not shown) of the housing body 2.

  Further, as the first lock rod 72a protrudes, the first rotating disk 75a rotates in the clockwise direction (see the direction of the arrow TL1) around the rotation shaft 74a in FIG. 10B, and the slide plate 34 is moved in FIG. ) In the direction of arrow SL, and the tip of the interlocking arm portion 23 is also moved in the direction of arrow SL in FIG. As a result, the grip arm portion 22 of the trigger body 15 rotates horizontally in the clockwise direction (the closing direction of the door 3) around the pivot shaft 24 in FIG. 11, and returns to the original state shown by the solid line in FIG. It is.

  By the way, as described above, when the trigger body 15 is not operated, the elastic biasing force of the tension spring 77 acts in a direction in which each lock rod 72 protrudes from the outer peripheral surface of the door 3. In this regard, the third embodiment also includes a lock rod storage mechanism 80 for holding each lock rod 72 so as not to protrude.

  That is, as shown in FIGS. 12 and 13, the substantially U-shaped support bracket 81 fixed in the vicinity of the third lock rod 72 c on the inner and rear surfaces of the door 3 has a restriction formed in an L-shaped plate shape. The middle part of the piece 82 is pivotally supported via a vertically oriented pin shaft 83 so as to be horizontally rotatable. The base end portion of the restricting piece 82 extends to the position of the third lock rod 72c, while the tip end portion of the restricting piece 82 is exposed to the outside from the opening hole 84 formed in the inner cover body 14. The outer periphery of the pin shaft 83 is fitted with a coil spring 85 that presses and urges the base end portion of the restricting piece 82 in a direction in contact with the third lock rod 72c.

  In the state where the door 3 is opened, the upper surface of the base end portion of the regulating piece 82 is brought into contact (hooked engagement) with the engaging claw portion 86 fixed to the third lock rod 72c which is in the immersive state. Until the door 3 is closed, the lock rods 72 are held so as not to protrude, and the immersion state (free state) is maintained (see FIGS. 12A and 13A). .

  Further, in this configuration, if the door 3 is pushed and closed to the back side (the closing direction of the door 3), the knob screw 87 provided on the inner lower portion of the housing main body 2 presses the tip of the regulating piece 82 forward, The hook engagement between the base end portion of the restricting piece 82 and the engaging claw portion 86 of the third lock rod 72c is released (see FIGS. 12B and 13B). As a result, all the lock rods 72 are held in a protruding state (locked state) protruding from the outer peripheral surface of the door 3 by the elastic biasing force of the tension spring 77, and as a result, the grip arm portion of the trigger body 15. 22 is held in the horizontal posture shown in FIG.

  Now, as shown in FIG. 10, the dial lock 8 as a locking means includes a dial housing 90 that moves forward and backward toward the second lock rod 72 b by the rotation operation of the dial knob 9. On the other hand, when each lock rod 72 is in the protruding state (locked state), the second lock rod 72b is engaged by being caught by the protruding dial housing 90 in the middle of the longitudinal direction of the second lock rod 72b. A hook-shaped piece 91 is provided to project rearward.

  When the lock rod 72 is protruded after the door 3 is closed and the dial lock 8 is operated to lock in this protruding state (locked state), the dial housing 90 moves forward and the hook-like piece 91 of the second lock rod 72b is moved. And the second lock rod 72b is prevented from immersing (the second lock rod 72b cannot slide). As a result, the second lock rod 72b and the other lock rods 72a and 72c are all held in the protruding state (locked state), and the door 3 cannot be opened.

  A cylinder lock 10 is provided below the first lock rod 72 a in the inner and rear surfaces of the door 5. The cylinder lock 10 includes a cylinder housing 92 that moves forward and backward toward the first lock rod 72a by rotating a key (not shown). On the other hand, an engaging claw 93 that engages and disengages the cylinder housing 92 when the first lock rod 72a is in the protruding state (locked state) is formed in the longitudinal middle portion of the first lock rod 72a.

  When the lock rod 72 is protruded after the door 3 is closed and the cylinder lock 10 is operated to lock in this protruding state (locked state), the cylinder housing 92 moves forward and the engaging claw 93 of the first lock rod 72a is moved. The first lock rod 72a becomes non-slidable (cannot be immersed). As a result, the second and third lock rods 72b and 72c are also held in the protruding state (locked state), and the door 3 cannot be opened.

  Also when comprised as mentioned above, the effect similar to 1st Embodiment is acquired.

(4). Fourth Embodiment FIG. 14 shows a fourth embodiment of the present invention. 14A is an enlarged rear view of the slide plate in the locked state in the fourth embodiment, and FIG. 14B is an enlarged plan sectional view of the handle member.

  The fourth embodiment is a modification of the third embodiment, and the interlocking arm portion in the trigger body 15 in a state where the slide plate 34 slides in the direction of the arrow SR on the slide plate 34 constituting the mechanical interlocking mechanism 13. 14 is formed on the pivot shaft 24 of the trigger body 15 as shown in FIG. 14 (see FIG. 14). In b), it is different from the third embodiment in that a coil spring 116 that always urges clockwise around the pivot shaft 24 (the closing direction of the door 3) is fitted. Other configurations are substantially the same as those of the third embodiment.

  With this configuration, if the hand is released from the handle member 5 after the door 3 is opened, the trigger body 15 can be returned to the original state shown by the solid line in FIG. 14B even if the door 3 is not closed. become. Needless to say, the configuration of the fourth embodiment may be incorporated into the first or second embodiment. Further, a long hole on the left and right may be formed at one end of the first turntable 75a, and a pin protruding from the slide plate 34 may be loosely fitted into the hole. Also in this case, as in the fourth embodiment, the trigger body 15 returns to its original position when the hand is released from the handle member 5.

(5). Fifth Embodiment FIG. 15 shows another example of the interlocking structure between the handle member 5 and the slide plate 34. In the fifth embodiment shown in FIG. 15, the interlocking arm portion 23 of the trigger body 15 constituting the handle member 5 is shorter than that of the first to fourth embodiments, while the slide plate 34 includes the door 3. An interlocking rod 117 protruding in the direction is provided so as to always contact the tip of the interlocking arm portion 23. Other configurations are generally the same as those of the third embodiment.

  In this case, when the gripping arm portion 22 of the trigger body 15 horizontally rotates in the counterclockwise direction (the opening direction of the door 3) around the pivot shaft 24 in FIG. 15 (see the two-dot chain line state), the interlocking arm portion 23 is Together with the gripping arm portion 22, it integrally rotates about the pivot shaft 24, and the interlocking rod 117 of the slide plate 34 is pressed in the direction of the arrow SR and slid by the pressing action of the tip portion. As a result, the engagement hole (not shown) of the housing main body 2 and the lock rod 72 are disengaged, and the door 3 is opened and closed (free state).

  Thereafter, when the door 3 is closed, using the elastic restoring force of the tension spring 37, the slide plate 34 and the interlocking rod 117 slide in the arrow SL direction, and the tip of the interlocking arm portion 23 is moved in the arrow SL direction. Press. As a result, the grip arm portion 22 of the trigger body 15 rotates horizontally in the clockwise direction (the closing direction of the door 3) around the pivot shaft 24 in FIG. 15, and returns to the original state shown by the solid line in FIG. It is. Note that the configuration of the fifth embodiment can be incorporated into the first or second embodiment.
