Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic lock device for a storage box with wings.

[0002]

2. Description of the Related Art In a storage box with a wing represented by furniture such as a cupboard, a bookshelf, a closet, and a makeup case, for example, a door (wing) is pivoted in a double door shape at an opening of a box body whose front is open. It is worn. In a storage box with a wing represented by the above-mentioned furniture, since a storage article is frequently taken in and out, a lock device is generally rarely provided, and even if a lock device is provided, a user does not use the lock device much. Many.

[0003] For this reason, as can be seen from the experience of the Great Hanshin Earthquake, when the storage box is greatly shaken due to a large earthquake, the closed door is opened due to the shaking, and the storage articles such as tableware are removed. It may jump out and cause damage to stored items or injury to occupants.

[0004]

Therefore, the inventor of the present application detects the large swing generated in the box body and automatically locks the wings to prevent the stored articles from jumping out. A patent has already been applied for a box auto-lock device (Japanese Patent Application No. 7-18).
1739, Japanese Patent Application No. 7-134376).

Among such auto-lock devices, the one in which the auto-lock device is incorporated in the storage box to improve the appearance (see Japanese Patent Application No. 7-134376) is a lock installed in the box body. An apparatus main body and a bracket attached to an inner surface side of the wing are provided, and the lock device main body is configured to move from an unlock position to a lock position to prevent opening of the wing when excessive shaking of the box main body occurs. It has a dead bolt that engages the bracket.

And, in this kind of auto-lock device,
In order to unlock the dead bolt that protrudes to the lock position, a release hole is provided in the top plate of the box body, and the protruding end of the dead bolt is pushed by the rod inserted into the release hole. Is to be returned to the unlocked position. However, the means for providing the release hole in the top plate of the box body has a problem that dust and oil stains enter the box body through the release hole of the box body.

Further, in order to unlock the dead bolt, it is necessary to insert a rod or the like through the unlocking hole and push the dead bolt from the locked position to the unlocked position. It was very troublesome. Further, although the above unlocking method can be adopted for furniture with a top plate, it cannot be used for a storage box provided at a corner of a ceiling or wall of a kitchen or the like because the top plate is not provided. Therefore, there is also a drawback in that the automatic lock device cannot be incorporated in this type of storage box.

In view of the above situation, the present invention enables the lock of the dead bolt to be released with one touch simply by pushing the wing in the closing direction, so that the lock can be easily released without providing a release hole in the box body. The purpose is to be able to do it.

[0009]

In order to solve the above technical problems, the present invention takes the following technical measures. That is, the present invention is characterized in that a lock releasing mechanism for returning the dead bolt to the unlock position by further moving the wing in the closing direction from the state in which the dead bolt is engaged with the bracket is provided. 1).

According to the present invention, when the wing is further moved in the closing direction from the state in which the dead bolt is engaged with the bracket (see the phantom line in FIG. 1, for example), the lock release mechanism unlocks the dead bolt. Since it is pushed back to the position, the deadbolt lock can be released with one touch just by pushing the wing in the closing direction. Therefore, for example, when the user hits a storage box for furniture or the like and the auto-lock device is accidentally locked without an earthquake, the dead bolt lock of the device can be released very easily. Become.

As a lock releasing mechanism for realizing the above function, for example, a cam mechanism for converting the movement of the wing in the closing direction into the movement of the dead bolt to the unlock position side (claim 2, FIGS. 1 to 22). Reference) and link mechanism (Fig. 23)
See) is possible. Of these, when the cam mechanism is adopted, a slider that moves in the wing opening / closing direction may be provided between the bracket and the dead bolt, and a cam portion for pushing back the dead bolt may be formed on the slider. Yes (see Figure 21 and Figure 22),
The cam mechanism includes a cam portion formed in a shape that pushes the dead bolt back toward the recessed side by directly contacting the protruding end portion of the dead bolt with the midway portion of the bracket that moves in the closing direction of the wing in the same direction. It is preferable.

In this case, since the dead bolt is pushed back to the retracted side by the direct contact between the bracket and the dead bolt, it is not necessary to separately provide an intermediate member such as the link mechanism or the slider, and the increase in the number of parts can be prevented. More specifically, the cam mechanism can be formed by a first cam portion formed in the middle of the wing opening / closing direction of the bracket and inclined toward the protruding side of the dead bolt as it approaches the dead bolt side (claim 4).

The cam mechanism can also be constituted by a second cam portion formed at the protruding end portion of the dead bolt and inclined toward the recessed side of the dead bolt toward the bracket side. Both parts may be adopted (Claim 5). Furthermore, it is preferable that the first cam portion employs a spring member attached to the bracket and elastically deformed in the direction in which the dead bolt moves in and out (section 6).

In this case, since the first cam portion made of the spring member is elastically deformed in the direction in which the dead bolt is extended and retracted, even if the mounting height of the wing is slightly changed, the first cam portion is made to protrude from the dead bolt. Can be reliably contacted with. On the other hand, when the first cam portion is adopted, since the bracket is a member that engages with the dead bolt to prevent the opening of the wing, the end portion of the bracket has a dead bolt protruding into the lock position. It is necessary to provide a hooking part to be hooked on the projecting end and to form a relief part between the hooking part and the first cam part to allow the dead bolt to project (claim 7).

Further, for example, when the dead bolt is in the locked position with the wings completely opened, the tip of the bracket interferes with the bolt unless the bolt is returned to the unlocked position. The wing cannot be closed. Therefore, even if the dead bolt is in the lock position, the third cam for pushing back the dead bolt protruding to the lock position to the retracted side is attached to the tip of the bracket so that the wing in the completely opened state can be easily closed. It is preferable to provide a part (claim 8). When the third cam portion is brought into contact with the second cam portion of the dead bolt, the pushing back action of the bolt to the retracted side becomes more reliable.

On the other hand, the dead bolt is provided in the main body of the lock device so as to be able to move in and out, so that it is inserted into the casing with some play. Therefore, when the protruding end of the dead bolt is pulled by the bracket in the opening direction of the wing, the dead bolt falls slightly in the same direction, and even if the dead bolt properly protrudes to the lock position, the bracket slips out of the protruding end and the wing It may not lock properly.

Therefore, the present invention recommends that the protruding end portion of the deadbolt be provided with a recess for ensuring that the bracket is caught by the retaining portion (claim 9). In this case, since the hooking portion of the bracket enters the recess of the dead bolt and is hooked on the deadbolt, the hooking portion of the bracket can be reliably caught even if the deadbolt slightly falls.

Further, according to the present invention, a guide rib extending in the opening / closing direction of the wing is provided on the outer surface of the lock device main body on which the deadbolt protrudes and retracts, and this guide rib has the same amount as the upper edge of the deadbolt at the unlock position or It is recommended to project it larger (claim 10). In this case, the guide rib protrudes by the same amount or larger than the upper edge of the dead bolt in the unlock position, so that the dead bolt in the unlock position does not engage the bracket. Therefore, even if the wings gradually fall due to, for example, deterioration of the hinges for many years, the latching portion of the bracket does not come into contact with the guide rib and does not latch onto the dead bolt at the unlocked position. You can avoid the unexpected situation that the wing is locked by the deadbolt in the position.

More specifically, the lock device body further includes a holding member which is movable in the opening and closing direction of the wing and whose tip is urged toward the dead bolt so as to lock the dead bolt. , A rolling member that rolls in the opening and closing direction of the wing due to the swing of the box body and collides with the holding member to release the tip end of the holding member from the dead bolt can be adopted. ).

In this case, the holding member is composed of a plate member having a clearance recess for accommodating the rolling member in the central portion, and the clearance recess is further formed at the bottom of the clearance recess toward the side opposite to the dead bolt. It is preferable to form an inclined edge that is inclined in the direction of deepening. If you do this,
The rolling member can be arranged closer to the edge of the escape recess of the holding member on the side opposite to the dead bolt. For this reason, the distance between the same edge portion in the escape recess and the rolling member is shortened, and the rolling member can collide with the holding member with a small amount of rolling, so that the sensitivity of the auto-lock device to shaking is reduced. Is improved.

At this time, the lower end of the first coil spring 17 is fitted onto the connecting pin 36 provided upright on the bottom wall 35 of the guide tube portion 21, and is housed in the spring housing hole 34 in a compressed state. For this reason, the dead bolt 16 is constantly urged upward by the first coil spring 17. A pair of left and right stoppers 37 are provided on the lower portion of the side surface of the dead bolt 16, and a vertical guide groove 38 is formed between the stoppers 37. A guide rail 39 extending vertically on the inner surface of the guide cylinder portion 21 is fitted into the guide groove 38 so that the dead bolt 16 is inserted into the guide cylinder portion 21.
It is inserted inside. Further, the stopper 37 restricts the dead bolt 16 from coming out by coming into contact with the front end portion 26A of the guide lid 26.

On the other hand, on the inner surface 5A of the door 5, the lock position B
A bracket 40 that is locked to the dead bolt 16 that protrudes to restrict the opening of the door 5 is fixed by a mounting screw 41. The bracket 40 is bent and formed in an L shape in a side view from a mounting plate 42 and a locking plate 43 orthogonal to the mounting plate 42. At the tip of the locking plate 43 of the bracket 40 (the end on the side of the storage box 3), a hooking portion 43A that hooks on the protruding end of the dead bolt 16 that has moved to the lock position B is provided.

The bracket 40 is attached to the inner surface 5A of the door 5 by screwing the mounting plate 42 with the mounting screw 41 so that the locking plate 43 projects rearward from the inner surface 5A. The mounting position is
In the closed state of the door 5, the locking plate 41 is at the same plane position as the position where the dead bolt 16 is retracted and retracted, and is at the height position where it enters the insertion space 24.

Therefore, when the dead bolt 16 is housed in the guide tube portion 21 (solid line in FIG. 1), the dead bolt 16 is released from the bracket 40, and the unlock for allowing the door 5 to be opened. It is at position A. On the other hand, when the dead bolt 16 projects into the space 24 (phantom line in FIG. 1), the upper portion of the dead bolt 16 enters the escape portion (engaging recess) 44 of the bracket 40 fixed to the door 5,
The lock position B is set in which the opening of the door 5 is blocked.

The fixed portion 20 of the casing 15 is formed with a storage portion 45 which extends in the front-rear direction (the opening / closing direction of the door 5, the same as the left-right direction in FIG. 1) so as to intersect with the withdrawal direction of the dead bolt 16. The holding member 18 is inserted through the central portion of the storage portion 45 in the left-right direction in a state of being guided so as to be movable in the front-rear direction. That is, the holding member 18 of the present embodiment is made of a metal slide plate formed in a substantially rectangular plate shape, and is vertically provided between the guide grooves 46 in the front-rear direction that are recessed in the center of the bottom surface 45A of the storage portion 45. By being fitted in the direction, it is guided in the storage portion 45 so as to be movable in the front-rear direction. In addition, the rolling member 19A that projects upward from the bottom surface 45A following the upper edge of the side wall of the guide groove 46.
The guide ridge 47 is provided in parallel with the groove 46.

The plate-shaped holding member 18 is provided with a hooking piece (hooking portion) 49 which fits into a hooking recess 48 formed on the side surface of the dead bolt 16 at the front end thereof, and the holding member 18 is dead bolted. A connecting piece 51 for connecting the second coil spring 50 biasing to the 16 side is provided at the rear end portion. In addition, in the central portion of the holding member 18, the relief recess 5 that is wide open upward
2 is formed as a notch, and a releasing piece 53 for sliding the holding member 18 rearward against the second coil spring 50 is formed at the rear upper edge thereof.

The upper edge of the retaining piece 49 of the holding member 18 is formed with a taper portion 49A having a downward slope in the front in order to push the holding member 18 backward with the downward movement of the dead bolt 16. . On the other hand, as shown in FIG.
The second coil spring 50, which is attached by externally fitting the connecting piece 51 of the holding member 18, abuts the rear end wall portion of the storage portion 45 and constantly urges the holding member 18 forward. By the biasing force of the coil spring 50, the hooking piece 49 of the holding member 18 is formed.
Is forcibly fitted into the hooking recess 48 of the dead bolt 16, whereby the dead bolt 16 can be held in the unlock position A in advance.

The auto-locking means 19 of this embodiment comprises a roller-shaped rolling member 19A, which is housed in the housing part 45 together with the plate-shaped holding member 18 so that the axis line thereof is orthogonal to the guide groove 46. Relief recess 5 of holding member 18
It is provided in 2 so as to be able to roll forward and backward. For this reason,
When the rolling member 19A moves rearward along with the swing of the box body 3, the rolling member 19A collides with the releasing piece 53 of the holding member 18 to release the holding member 18 from the dead bolt 16.

Further, the rolling member 19A is made of a metal round bar whose diameter is smaller than the longitudinal length of the accommodating portion 45 and smaller than the accommodating space height, and is guided by the guide groove 46 in the accommodating portion 45. An inertial force (collision sufficient to push the holding member 18 being pushed backwards against the elastic force of the second coil spring 50 due to the shaking during the earthquake (for example, shaking with a seismic intensity of about 2 to 3). It is designed to generate a force.

As the material of the rolling member 19A, a metal that can roll reliably with high sensitivity due to shaking of seismic intensity of about 2 to 3 due to an earthquake, etc. For example, brass is preferably used, but a steel material may be coated on its outer periphery with a resin.
Also, a resin in which a metal having a high specific gravity such as lead is embedded in a resin can be adopted.

Further, the guide ridge 47 is formed by the rolling member 19
It is designed so that the rolling frictional resistance of A is as small as possible, and in the central portion of the bottom surface 45A of the storage portion 45,
Two lines are provided along both side edges of the opening of the guide groove 46. Thus, the bottom surface 52 of the escape recess 52 of the holding member 18
The middle part of the holding member 18 is formed so as to fit within the guide groove 46 so that A is lower than the upper end surface of the guide protrusion 47, whereby the rolling member 19A is held in the escape recess 52. Since it rolls without coming into contact with the member 18, its rolling resistance is reduced and the operation sensitivity at the time of an earthquake is improved.

The rolling member 19A reciprocally rolls back and forth within the storage portion 45 when the box body 3 swings. When the swing is large due to an earthquake or the like, inertia caused by the rolling is generated. Holding member 1 with increased force
It strongly collides with the release piece 53 of No. 8. Due to this collision, the holding member 18 biased forward by the second coil spring 50 is displaced rearward (left side in FIG. 1) and the hooking piece 49 of the holding member 18 is separated from the hooking recess 48 of the dead bolt 16. Then, thereafter, the dead bolt 16 is projected upward by the first coil spring 17 to reach the lock position B.

As shown in FIG. 1, the locking plate 43 of the bracket 40 is provided with a relief portion 44 which is formed by bending upward a portion from the tip portion to the middle portion. This escape section 4
When the door 5 is completely closed (solid line in FIG. 1), 4 is formed so as to be located slightly behind the dead bolt 16 (inside the box body 3). The base end bent portion is located exactly on the rear side surface of the dead bolt 16.

Therefore, the dead bolt 16 is locked at the lock position B.
1 can be projected when the door 5 is slightly opened and the escape portion 44 is directly above the dead bolt 16 as shown by a phantom line in FIG. The dead bolt 16 that protrudes into the relief portion 44 has the protruding end portion that engages with the hooking portion 43A of the bracket 40.
And restricts the wing 5 from moving in the opening direction.

Further, as shown in FIG. 1, in the auto lock device, the door 5 is further moved in the closing direction from the state where the dead bolt 16 is engaged with the bracket 40 (state of the phantom line in FIG. 1). Therefore, the lock release mechanism 63 for pushing the dead bolt 16 back to the unlock position A is provided. In the present embodiment, the lock release mechanism 63 serves as the bracket 40 that moves in the closing direction of the door 5.
The first and second cam portions 6 are formed in a shape that pushes the dead bolt 16 downward, which is the retracted side, by directly contacting the protruding end portion of the dead bolt 16 in the same direction.
A cam mechanism 63A composed of 1, 62 is adopted.

More specifically, the first cam portion 61 is
The locking plate 42 of the bracket 40 is formed in a middle portion of the bracket 40 so as to be inclined forward and downward. In other words, this first cam portion 61
Is formed in the bracket 40 at an intermediate portion in the opening / closing direction of the door 5 so as to incline toward the protruding side of the bolt 16 as the dead bolt 16 side (the storage box 3 side) is approached.

On the other hand, the second cam portion 62 has the dead bolt 1
6 is formed by cutting the projecting end face of the taper 6 so as to be inclined downward. In other words, the second cam portion 62 is formed on the protruding end portion of the dead bolt 16 and moves toward the bracket 40 side (outside the box 3).
Is formed so as to incline toward the immersion side. For this reason,
The dead bolt 16 protruding to the lock position B has the escape portion 44.
When the door 5 is moved from the engaged state to the closed position, the cam portions 61 and 62 press against each other to push the dead bolt 16 to the unlocked position A.

That is, when the door 5 is further moved in the closing direction from the state where the dead bolt 16 is engaged with the bracket 40 (the state where the projecting end portion of the dead bolt 16 has entered the relief portion 44), the bracket 40 of the bracket 40 is moved. First cam part 6
1 contacts the second cam portion 62 of the dead bolt 16, and the dead bolt 16 is pushed back to the unlock position A.

Further, a third cam surface 64 is provided at the tip of the locking plate 43 of the bracket 40, and is curved forward and downward at substantially the same angle as the first cam portion 61. The third cam surface 64 is moved to the closing direction by moving the door 5 which is completely opened so that all the parts of the bracket 40 are located outside the storage box 3, and the dead bolt in the lock position B is also moved. When the dead bolt 16 projects to the lock position B in the state where the door 5 is large and completely opened, the dead bolt 16 and the bracket 40 interfere with each other and the door 16 is pushed. Prevent 5 from not closing.

That is, the door 5 is large and completely opened (the door 5 is located further to the right of the phantom line in FIG. 1).
When the dead bolt 16 protrudes to the unlocked position A, the door 5 is closed and moved from this state, and the second cam surface 6
2 and the third cam surface 64 are pressed against each other and the dead bolt 16
Is pushed toward the unlock position A, whereby the tip of the bracket 40 can ride over the dead bolt 16, so that even when the dead bolt 16 is in the lock position B, the door 5 in the completely opened state can be easily closed. Enables smooth closing of the door 5.

According to the auto lock device of the first embodiment, the dead bolt 1 is resisted against the first coil spring 17.
When 6 is pushed down, the hooking piece 49 of the holding member 18 passes through the taper portion 49A and fits into the hooking recess 48, and holds the dead bolt 16 in the unlocked position A. For this reason, the deadbolt 16 is always held at the unlock position A in a normal case where no large swing occurs in the box body 3, and in this case, the door 5 can be freely opened and closed.

On the other hand, when a shake larger than the expected seismic intensity occurs in the box body 3, the rolling member 19A moves into the holding member 1.
The holding force of the hooking piece 49 is released by the impact force when the release piece 53 of FIG. Therefore, when the door 5 is slightly opened and the escape portion 44 of the bracket 40 comes directly above the dead bolt 16 as shown by the chain line in FIG. 1, the dead bolt 16 automatically moves to the lock position B, The protruding end of the dead bolt 16 is caught by the hooking portion 43A of the bracket 40, and the opening of the door 5 is blocked.

As a result, stored items such as tableware in the storage box 2 are prevented from popping out. And
When the door 5 is further moved in the closing direction from the state where the dead bolt 16 is engaged with the bracket 40 as described above, the first cam portion 61 of the bracket 40
6, the bolt 16 is brought into contact with the second cam portion 62 at the upper end and pushed back to the unlock position A, after which the holding member 18 holds the dead bolt 16 at the unlock position A, thereby releasing the lock. it can.

As described above, in this embodiment, since the lock by the dead bolt 16 can be released with one touch by simply pushing the door 5 in the closing direction, the automatic lock device locks with a slight vibration regardless of an earthquake. Even if it happens, the lock can be released by an extremely simple operation. Further, since the lock can be released by the extremely simple operation of pushing back the door 5, even if the sensitivity of the shake detection of the automatic lock device is increased, the use of the storage box 2 is not inconvenient, and therefore, the same. The sensitivity of the shake detection of the device can be made extremely sensitive.

In the above embodiment, the left and right doors 5
When a strip-shaped mating member that closes the gap between the two doors 5 is fixed to the edge of one of the doors 5, the other door 5 cannot be opened unless the other door 5 is opened. I ca n’t
It suffices to provide the bracket 40 only on the other door 5 and provide the box body 3 with one lock device body 1 for automatically locking the bracket.

However, when the summing member is pivotally attached to one of the doors 5 so as to be swingable, brackets 40 are provided on both the left and right doors 5 as in a fourth embodiment described later.
It is necessary to provide the lock device main body 1 at each position of the box main body 3 corresponding to these brackets 40.
Further, in the case of the storage box 2 having the one-sided door 5, the lock device main body 1 can be attached to the vertical side surface of the box main body 3.

In the first embodiment, as shown by the alternate long and short dash line in FIG. 1, the lower rear end of the holding member 18 (below the connecting piece 51) is formed as an inclined side 55,
The corner point O at the lower end of the rear part may be located at a position forward from the collision point P of the rolling member 19A by a distance S. When the inclined side 55 is formed, when the rolling member 19A collides with the release piece 53, the holding member 1 uses the corner point O as a fulcrum.
Since the lower surface 18A of No. 8 slightly lifts up from the groove bottom 46A and retreats slightly, the hooking piece 49 of the holding member 18 easily separates from the hooking recess 48 of the dead bolt 16, thereby improving the sensitivity. be able to.

6 to 8 show a second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the auto-locking means 19 has a ball-shaped rolling member 1.
9B and the point that the bottom surface 45A of the housing portion 45 of the casing 15 is a cylindrical surface, and other configurations are similar to those of the first embodiment described above. Therefore, the drawings are given the same reference numerals as those in FIGS. 1 to 5, and detailed description thereof will be omitted.

In the second embodiment as well, the lower portion of the holding member 18 can be the inclined side 55 as shown by the chain double-dashed line. Further, the present invention is not limited to the storage box 2 but also furniture such as a bookshelf and a closet, and a wing (door).
Can be widely used in storage boxes equipped with. FIG. 9 shows a modified example of the bracket 40, in which the tip portion of the locking plate 43 of the bracket 40 is bent in the front downward direction to form the third cam portion 64. That is, the third cam portion 64 is configured by bending the front end portion of the locking plate 43 forward and downward at substantially the same angle as the first cam surface 61. The other points are the same as those of the first embodiment.

In each of the above-described embodiments, the bracket 40 is provided with the first cam portion 61 and the dead bolt 16 is provided with the second cam portion 62. When the door 5 is closed and moved by these cam portions 61 and 62, the dead cam is dead. Although the cam mechanism 63 that presses the bolt 16 to the unlock position A is configured, instead of this, the cam portion 61 is provided only on the bracket 40, and only the cam portion 61 moves the wing 5 in the closing direction. So that the bracket 40 is in the lock position B.
6 may be pushed to the unlocked position A. Further, the cam portion 62 is provided only on the dead bolt 16, and only the cam portion 62 moves the dead bolt 16 at the lock position B by moving the wing 5 in the closing direction.
It may be pushed to the unlock position A by 0.

That is, the cam mechanism 63A can be constructed not only of both the first and second cam portions 61 and 62, but also of either one of them. Further, in each of the above-described embodiments, the auto-locking means 19 for detecting the swing and releasing the holding member 18 from the dead bolt 16 is constituted by a roller-shaped or ball-shaped rolling member 19A. , The automatic locking means 19 and the holding member 1
8 is a weight member that slides with respect to 8 (for example, Japanese Patent Application No. 7-13
No. 4376).

In addition, in each of the above-described embodiments, the storage box 2 is configured to urge the door 5 in the closing direction by the spring incorporated in the hinge 6, but instead of this,
The storage box 2 may be configured so that the door 5 is attracted and held in the closed position by a magnet, or may be a storage box having no mechanism for holding the door 5 in the closed position.

10 to 15 show a third embodiment of the present invention. The auto lock device of this embodiment,
The basic structure and operation are almost the same as those of the first embodiment, but various improvements are made in various places. Therefore, the points of improvement will be mainly described below, and the members having the same structure and function as those in the first embodiment will be denoted by the same reference numerals and the description thereof will be omitted.

First, in this embodiment, as the first cam portion 61 formed on the bracket 40 side, a spring member 71 attached to the bracket 40 and elastically deformed in the protruding / retracting direction of the dead bolt 16 (vertical direction in the illustrated example). Has been adopted. As shown in FIG. 10, the spring member 71 includes a fixed plate portion 72 fixed to the inner surface of the mounting plate 42 of the bracket 40.
And a contact plate portion 73 extending rearward from the upper edge of the fixed plate portion 72. The spring member 71 may be a bar-shaped spring instead of a leaf spring.

The abutting plate portion 73 has a substantially doglegged shape in a side view by bending a middle portion thereof downward, and a dead end is formed by forming a portion from the bending portion to the tip end in a front downward direction. The contact portion 74 (first cam portion 61) for the protruding end portion of the bolt 16 is provided. The abutting portion 74 is inclined at substantially the same angle as the second cam portion 62 of the dead bolt bolt 16 in a state where the contact portion 74 enters the escape portion 44 of the bracket 40, and is longer than the second cam portion 62. It has a contact surface.

As shown in FIGS. 10 and 13, at the central portion in the width direction of the locking plate 43 of the bracket 40, the interference between the abutting plate portion 73 elastically deformed upward and the locking plate 43 is prevented. An escape slot 75 is provided to avoid it. In addition, in the present embodiment, the protruding end portion of the dead bolt 16 is provided with the recessed portion 76 for ensuring that the bracket 40 is caught by the retaining portion 43A.

As shown in FIGS. 10 and 11, the recess 76 is formed by shallowly engraving the rear side surface of the protruding end of the bracket 16 over a certain range in the vertical direction. The hooking portion 43A of 40 is
It is hooked on the projecting end of the dead bolt 16 while entering the recess 76 (see FIG. 10). Further, in the present embodiment, a pair of left and right guide ribs 78 extending in the front-rear direction (opening / closing direction of the door 5) is provided on the upper surface of the lid member 77.
Is provided.

As shown in FIGS. 11 and 12, the guide rib 78 is erected at a position sandwiching the insertion hole 79 of the dead bolt 16 from the left and right, and extends from the tip edge of the lid body 80 to the base of the spacer portion 81. It extends in the front-back direction over the entire range. The protrusion height of the guide rib 78 is set to be equal to or larger than the upper end edge of the dead bolt 16 held at the unlocked position A.

Further, as shown in FIGS. 10 and 11, in the present embodiment, the bottom of the escape recess 84 of the holding member 83 is
An inclined edge 85 is formed that is inclined in a direction in which the relief recessed portion 84 becomes deeper toward the rear side (counter to the dead bolt 16 side), and by this inclined edge 85, the rolling member 19B is always located near the release piece 86. I am trying to do it. Therefore, if the rolling member 19B slightly rolls,
B can be made to collide with the release piece 86 of the holding member 83, and the sensitivity of the autolock device to shaking can be improved.

In the third embodiment, the spring member 71 is attached to the bracket 40 to widen the vertical contact range with respect to the dead bolt 16. Therefore, in the case of the first embodiment (FIG. 1). Compared with the above, the vertical length of the spacer portion 81 of the lid member 77 is increased so that the spring member 71 can also be inserted into the insertion space 87. In addition, in this embodiment, as in the second embodiment, a ball-shaped rolling member 19B is adopted.

Further, as shown in FIG. 11, the casing 1
5 is integrally formed by covering the guide tube portion 21 at the front end thereof with a rounded cover member 88 to form a square with four rounded corners in plan view. Next, the operation of the auto lock device according to the third embodiment will be described with reference to FIGS. 14 and 15.

First, as shown in FIG. 14A, when the dead bolt 16 is held at the unlocked position A, the locking plate 43 of the bracket 40 and the spring member 71 are both on the lock device body 1 side. It is possible to freely move between the insertion spaces 87, and in this case, the door 5 can be freely opened and closed. On the other hand, as shown in FIG.
When a shake larger than the assumed seismic intensity occurs, the holding piece 49 releases the holding by the impact force when the rolling piece 19A collides with the releasing piece 53 of the holding member 18. Therefore, when the door 5 is slightly opened and the escape portion 44 of the bracket 40 comes directly above the dead bolt 16 as shown by the chain line in FIG. 1, the dead bolt 16 is automatically locked by the lock position B.
To the bracket 4, and the protruding end of the dead bolt 16 moves to the bracket 4.
It is caught by the hooking portion 43A of 0 and the opening of the door 5 is blocked.

At this time, in this embodiment, the bracket 4
Since the engaging portion 43A of 0 is engaged with the recess portion 76 of the dead bolt 16 so that they engage with each other, play of the casing 15 against the guide tubular portion 21 or the like causes the dead bolt 1
Even if 6 falls slightly in the opening direction of the door 5, the bracket 40
It is possible to prevent the hook portion 43A from coming off in the opening direction of the door 5.

Then, when the door 5 is moved in the closing direction from the state where the dead bolt 16 shown in FIG. 14 (b) is engaged with the bracket 40, the first cam portion 6 of the bracket 40 is moved.
1 (spring member 71) contacts the second cam portion 62 at the upper end of the dead bolt 16 to push the bolt 16 back to the unlock position A, and then the holding member 83 holds the dead bolt 16 at the unlock position A. As a result, the lock by the dead bolt 16 is released.

In this case, in this embodiment, the first cam portion 6
Since the spring member 71 which is elastically deformable in the vertical direction is adopted as the first unit, the same as shown in FIGS. 14 (b), 15 (a) and 15 (b) due to rattling of the door 5 and mounting error of the bracket 40. Even if the mounting height of the bracket 40 is slightly changed, the first cam portion 61 surely comes into contact with the projecting end portion (second cam portion 62) of the dead bolt 16, and thus the cam mechanism 63A is used. The unlocking mechanism 63 can be operated more reliably.

Further, as shown in FIG. 14C, even if the dead bolt 16 is projected while the door 5 is completely open, if the door 5 is still moved in the closing direction,
Since the third cam portion 64 formed at the tip of the bracket 40 pushes down the second cam portion 62 of the dead bolt 16, the door 5 can be easily closed without pushing back the dead bolt 16 with a finger.

Further, in this embodiment, since the guide rib 78 projects by the same amount or larger than the upper edge of the dead bolt 16 in the unlock position A, the door 5 is gradually lowered due to deterioration of the hinge 6 or the like. Even if it comes, the hooking portion 43A of the bracket 40 contacts the guide rib 78 and is not hooked by the dead bolt 16 in the unlock position A. Therefore, it is possible to prevent the door 5 from being locked by the dead bolt 16 in the unlock position A.

16 to 20 show a fourth embodiment of the present invention, and in this embodiment, a summing member 91.
In the case where the auto-lock device according to the third embodiment is adopted in the storage box 2 in which the same member 91 is pivotably attached to one door 5 so that the door 5 provided with can be opened and closed independently. Shows. In FIG. 16, the storage box 2
Is used for furniture such as a closet, a tableware case, a makeup case, and the like.

The portion 4 is provided with a pair of left and right doors 5L and 5R that closes the opening 4 so as to be openable and closable.

The pair of left and right doors 5L and 5R are so-called double-door type doors whose outer edges in the width direction are pivotally attached to the side plates 3A of the box body 3 via hinges or the like, and are rotatable inward and outward of the storage box 2. A handle 57 is fixed to the center of the outer surface of each of the doors 5L and 5R. A plate piece 92 is attached to the front ends of both doors 5L and 5R and to the lower part of the inner surface, and this plate piece 92 also serves as the bracket 40 required for the automatic lock device. That is, FIG. 16 and FIG.
As shown in, the mounting plate 42 of the bracket 40 is formed as a strip plate that is long in the width direction, and has a function as a plate piece 92 that is attracted to the magnet 11 of the contact member 10.

On the opening 4 side of the top plate 8 and the bottom plate 9 and at the center in the width direction, contact members 10 for fixing the summing member 91 to be described later are fixed. FIG.
6 and FIG. 19, the upper and lower contact members 10
In both cases, the contacting surface 93 of the summing member 91 is provided in the center of the front surface, and the plate piece 92 is attracted to both doors 5L, 5L.
It has magnets 11 for closing R on both left and right front sides. Further, of the upper and lower contact members 10, the casing 15 of the auto lock device is integrally incorporated at both left and right ends of the upper contact member 10U.

That is, in the casing 15 of the auto lock device, the dead bolt 16 is attached to the front side (the box body 3).
Of the contact member 10U so as to face the opening recesses of the contact member 10U.
The mounting recess 11A serves as a mounting portion for the casing 15 and also serves as a space for securing the insertion space 24.

Thus, in this embodiment, the contact member 1
Since the casing 15 of the auto-lock device 1 is integrated into the 0, the casing 15 of the auto-lock device 1 is attached to the top plate 8 at the same time when the contact member 10 is fixed to the top plate 8. Further, if the bracket 40 is arranged so that the mounting plate 42 thereof is attracted to the magnet 11, the dead bolt 16 and the bracket 40 can be aligned at the same time, so that the labor for mounting the bracket 40 can be reduced.

Since the internal structure of the auto lock device itself is the same as that of the third embodiment, the same reference numerals are given to the drawings and the description thereof will be omitted. Further, in the present embodiment,
Although the lower locking member 10L is not provided with the auto-lock device 1, if the space for operating the dead bolt 16 can be secured from the release hole 54 provided in the bottom plate 9, the lower locking member 10L is Can also be provided with an auto-lock device 1.

The summoning member 91 is provided on both doors 5 when the door is closed.
It is for closing the gap e between the tips of L and 5R, and a pair of upper and lower auto hinges 9 are provided on the inner surface of the tip of the left door 5L.
It is pivotally mounted around the shaft 100 in the up-down direction and swingable in the inner and outer directions of the storage box 2 via the shaft 5. The summing member 91 is made of a long strip plate material having substantially the same length as the inner air height of the box body 3, and is formed in an arcuate cross-section so that the edge portion on the right side in the width direction makes smooth sliding contact with the contact member 10U. Has been done.

As shown in FIG. 17, the pair of upper and lower auto hinges 95 are provided with a fixed wing 96 fixed to the tip of the left door 5L and a movable wing 97 supporting the summing member 91. On the surface of the fixed wing 96, a pair of pivot brackets 98 facing each other and a restricting wall 99 connecting one side edge of the bracket 98 are erected, and the shaft 100 is vertically moved between the brackets 98. It is erected in the direction.

The movable wing 97 is fixed to the inner surface of the summing member 91 and rotatably supports the summing member 91, and an arm extending from one side edge of the support plate 101 in the width direction. The shaft 100 is inserted into the tubular portion 103 disposed between the pivot brackets 98 by including the portion 102 and the pair of upper and lower tubular portions 103 provided at the distal end of the arm portion 102. It is attached so that it can rotate around.

The movable wing 97 has its arm portion 102.
Is made of a resin material such as plastic that is elastically deformable in the rotating direction. Arm 102 of movable wing 97
Has a contact surface 104 with the restriction wall 99 on the back side, which is bent in a V shape in cross section, and as shown in FIG. 19, the rotation angle α of the movable blade 97 with respect to the fixed blade 96 is the arm. Part 1
The contact surface 104 of 02 is set to be smaller than 90 degrees by contacting with the restriction wall 99.

The summing member 91 is moved to the left door 5 so that the rotation angle α of the movable wing 97 faces the right door 5R side.
By fixing it to L, the swinging range of the summing member 91 to the left is regulated within 90 degrees. A winding spring 105 for biasing the arm portion 102 of the movable blade 97 toward the regulating wall 99 side of the fixed blade 96 is fitted between the cylindrical portions 103 of the shaft 100. The summing member 91 is always urged in the inward swinging direction by 105 when it is attached to the left door 5L. Therefore, the summing member 91 is similar to that shown in FIG.
As shown in FIG. 9, when the door 5L is opened, the door 5L is held in a state of being inclined inward by the rotation angle α from the inner surface of the door 5L.

In the storage box 2 having the calling device of the above construction, first, as shown in FIG. 19, when the left side door 5L is open and the right side door 5R is closed, The mating member 91 is biased inward (upward in FIG. 19) by the winding spring 105, so that the mating member 91 is held in a state of being tilted by the turning angle α from the inner surface of the left door 5L.
