In one example, the first installation member 10 is installed on the back surface 120A of the second door 120, and the second installation member 40 is installed on the partition 320. It is preferable that the positions of the installation members 10 and 40 in the height direction of the storage structure 200 are the same as the positions of the handles on the door of a general structure installed in the building.

As shown in FIG. 4, the main elements constituting the first installation member 10 are the regulated member 20 and the mounting portion 30. The regulated member 20 is configured to be able to lock the second door 120 that closes the storage space 210 by coming into contact with the regulating member 70 provided on the second installation member 40. The mounting portion 30 is configured so that it can be mounted on the door 100, the wall 310, and the like. The regulated member 20 and the mounting portion 30 are individually configured members and are connected by a coupling means. Examples of bonding means are welds, adhesives, screws, and irregularities to be fitted. The specific form of the regulated member 20 and the mounting portion 30 can be arbitrarily selected. In one example, the regulated member 20 is a metal hook, and the mounting portion 30 is a metal plate.

The regulated member 20 is divided into a base portion 21 and a contact portion 22. The base portion 21 is a plate joined to the mounting portion 30. The contact portion 22 is a claw protruding upward from the tip portion of the base portion 21. The contact portion 22 is formed with an inclined surface 22A and a regulated surface 22B that come into contact with the regulating member 70. The inclined surface 22A is formed on the tip end side portion of the contact portion 22 so as to incline from the tip end side to the base end side of the contact portion 22 toward the upward side from the base portion 21 side of the contact portion 22. The regulated surface 22B is formed on the portion of the contact portion 22 on the mounting portion 30 side so as to follow the longitudinal direction of the box 50.

The mounting portion 30 is fixed to the back surface 120A of the second door 120. The material constituting the mounting portion 30 can be arbitrarily selected. In a preferred example, the mounting portion 30 is made of a magnetic material such that the magnet 81 of the operating member 80 can be attracted to the mounting portion 30 via the second door 120. In this case, the operating member 80 can be used as the handle of the door 100. Examples of magnetic materials are iron, silicon steel, permalloy, sendust, permendur, soft ferrite, amorphous magnetic alloys, and nanocrystal magnetic alloys. Examples of magnets 81 are ferrite, neodymium, samarium-cobalt, and alnico. The coupling means for coupling the mounting portion 30 to the door 100 can be arbitrarily selected. In the first example, the connecting means is a means for connecting the mounting portion 30 to the door 100 by using a fixing member. Examples of fixing members are screws, bolts, and rivets. In the second example, the coupling means is a means for coupling the mounting portion 30 to the door 100 by utilizing the adhesive force. Examples of objects that provide adhesive strength are adhesives and double-sided tape. In the third example, the coupling means is a means for coupling the mounting portion 30 to the door 100 by using a magnetic force. An example of an object that provides magnetic force is a magnet provided on one of the mounting portion 30 and the door 100, and a magnet or magnetic material provided on the other of the mounting portion 30 and the door 100.

The main elements constituting the second installation member 40 are the box 50 and the mounting portion 60. The materials constituting the box 50 and the mounting portion 60 can be arbitrarily selected. One example is a lightweight resin material. The box 50 and the mounting portion 60 are individually configured resin members and are joined by an adhesive. The shape of the box 50 is rectangular. The box 50 is composed of a first side wall 51, a second side wall 52, a third side wall 53, a top wall 54, and a bottom wall 55. These elements constituting the box 50 are individually configured resin members and are joined by an adhesive. The first side wall 51 and the second side wall 52 face each other via the space 50A. Slits 51B and 52B through which the regulated member 20 can pass are formed in the side walls 51 and 52. The slits 51B and 52B are formed in the range from the top wall 54 to the bottom wall 55. The third side wall 53 is provided between the end of the first side wall 51 and the end of the second side wall 52. The mounting portion 60 is a plate and is joined to each of the first side wall 51 and the second side wall 52 so as to face the third side wall 53 via the space 50A. The second installation member 40 is installed in the partition 320 by fixing the mounting portion 60 to the partition 320. The second installation member 40 is installed so that the longitudinal direction of the box 50 is along the longitudinal direction of the partition 320. An example of the means for connecting the mounting portion 60 and the partition 320 is the same as the means exemplified as the means for connecting the mounting portion 30 and the second door 120.

The regulating member 70 is arranged in the space 50A so that the space 50A of the box 50 can be moved. The material constituting the regulating member 70 can be arbitrarily selected from a magnetic material and a magnet. The magnetic material constituting the regulating member 70 can be selected from the examples of the magnetic material constituting the mounting portion 30. The magnet constituting the regulating member 70 can be selected from the example of the magnet 81. The shape of the regulating member 70 can be arbitrarily selected. Examples are spheres, cylinders, prisms, plates, and hooks. In the illustrated example, the regulatory member 70 is a metal sphere. A plurality of support portions 56 for holding the regulating member 70 at a position higher than the bottom wall 55 of the box 50 are provided on the inner surface of the box 50. The regulating member 70 can move between the support portion 56 and the top wall 54 in the space 50A of the box 50. The material constituting the support portion 56 is the same as the material constituting the box 50. The support portion 56 is a resin member individually configured from each side wall 51 to 53 and the mounting portion 60, and is joined to each side wall 51 to 53 and the mounting portion 60 by an adhesive.

The regulating member 70 moves with respect to the box 50 by the magnetic force of the operating member 80 or the force applied from the regulated member 20. When the magnetic force of the operating member 80 is applied to the regulating member 70, the regulating member 70 is attracted to the magnet 81 of the operating member 80 via the box 50, the mounting portion 30, and the door 100 to move the operating member 80. Moves to the box 50. When the regulated member 20 moves in the closing direction of the door 100 so as to push up the regulating member 70 by the inclined surface 22A of the contact portion 22, the regulating member 70 moves with respect to the box 50 along the inclined surface 22A. The inclination angle of the inclined surface 22A can be arbitrarily selected. In one example, when the contact portion 22 moves to push up the restricting member 70, the inclination angle of the inclined surface 22A is set so that the regulating member 70 can smoothly move along the inclined surface 22A.

The first guide surface 51A, which is the inner surface of the first side wall 51, and the second guide surface 52A, which is the inner surface of the second side wall 52, define the moving direction of the regulating member 70 in the space 50A of the box 50. The diameter of the regulating member 70 is slightly shorter than the distance between the first guide surface 51A and the second guide surface 52A. Therefore, a minute gap is formed between the regulating member 70 and each of the first side wall 51 and the second side wall 52, and the moving direction of the regulating member 70 with respect to the box 50 is substantially defined in the longitudinal direction of the box 50. Has been done. Such provisions regarding the moving direction are realized by the guide surfaces 51A and 52A, respectively. Since the moving direction of the regulating member 70 is specified, severe operation accuracy is not required when operating the operating member 80 to move the regulating member 70, so that the lock and unlock of the door 100 can be easily changed. can.

The operation member 80 applies a magnetic force to the regulation member 70 so that the regulation member 70 moves with respect to the first installation member 10 and the second installation member 40. The main elements constituting the operating member 80 are the magnet 81 and the grip 82 for holding the magnet 81. The magnet 81 is fixed to the grip 82. The material constituting the grip 82 can be arbitrarily selected. One example is a lightweight synthetic resin. When the grip 82 is made of this material, the operability of the operating member 80 by the user is improved. When the regulating member 70 is moved by using the operating member 80, as shown in FIG. 5, the operating member 80 is placed on the surface 120B of the second door 120 so as to be coupled to the mounting portion 30 via the second door 120. Will be installed. In this state, since the magnet 81 of the operating member 80 and the mounting portion 30 are coupled to each other, the operating member 80 is maintained in the state of being installed in the second door 120 even if the user does not support the operating member 80. .. When the operating member 80 installed on the second door 120 moves upward along the second door 120 while the regulating member 70 is located below the top wall 54 of the box 50, the regulating member 80 is moved upward together with the operating member 80. 70 moves upwards. When the operating member 80 installed on the second door 120 moves downward along the second door 120 while the regulating member 70 is located above the support portion 56 of the box 50, the regulating member 80 is moved downward together with the operating member 80. 70 moves down.

The storage structure 200 includes a storage structure for storing the operating member 80. The configuration of the storage structure can be selected arbitrarily. In the first example, the storage structure is a magnetic material provided on the door 100. In the second example, the storage structure is a magnetic material provided on the outer surface of the storage space 210 of the wall 310. In the third example, the storage structure is a storage portion provided on the surface of the door 100 or the outer surface of the storage space 210 of the wall 310. An example of the storage unit is a case for storing the operation member 80. According to the first example and the second example, the operating member 80 is held on the surface of the door 100 or the surface outside the storage space 210 of the wall 310 by coupling the magnet 81 of the operating member 80 and the magnetic material. The magnetic material 83 shown in FIG. 3 is an example of the magnetic material in the first example. The magnetic body 83 is fixed to the back surface 120A of the second door 120. The installation location of the magnetic body 83 in the height direction of the second door 120 can be arbitrarily selected. In a preferred example, the magnetic material 83 is placed out of the reach of infants.

In the storage structure 200, since the operation member 80 is used as a handle of the door 100, a general door handle is not provided on the surface of the door 100. When the magnetic material constituting the storage structure is provided on the back surface of the door 100, neither the handle nor the storage structure is provided on the surface of the door 100. Therefore, it is difficult to recognize the difference between the door 100 and the wall 310. By utilizing such characteristics, the storage structure 200 can be used as a hidden storage.

The door 100 is provided with a marker 90 that assists the use of the lock device 1. The marker 90 is provided to indicate the approximate position of the regulating member 70 to the user located on the front side of the door 100. When the restricting member 70 is moved by using the operating member 80, the user can easily recognize where on the door 100 it is appropriate to install the operating member 80. The configuration of the marker 90 can be arbitrarily selected. In a preferred example, the marker 90 is configured so as not to interfere with the movement of the operating member 80 along the surface of the door 100. One example is the seal and paint layers. In the illustrated example, the marker 90 is a sticker affixed to the surface of the door 100. The color or pattern on the surface of the marker 90 (hereinafter referred to as “color or the like”) can be arbitrarily selected. In a preferred example, the surface color or the like of the marker 90 matches or is similar to the surface color or the like of the door 100. In this case, the presence of the marker 90 is difficult to recognize at first glance, so that the aesthetic appearance of the door 100 is maintained.

As shown in FIG. 5, when the lock device 1 locks the door 100, the contact portion 22 of the regulated member 20 projects from the slit 52B of the second side wall 52 of the box 50 to the outside of the box 50, and the regulated member 20. 70 is supported by the support portion 56. In this state, when an operation of applying a force for moving the second door 120 in the opening direction to the second door 120 (hereinafter referred to as “opening operation”) is performed, the regulated member 20 fixed to the second door 120 is pressed. It tries to move in the direction of exiting the box 50 through the slits 51B and 52B of the box 50. This movement is regulated by the restricting member 70 arranged on the support portion 56 being sandwiched between the contact portion 22 and the first side wall 51. Therefore, the movement of the second door 120 in the opening direction is restricted, and the second door 120 does not open. When the lock device 1 locks the door 100 and the opening operation is not performed, a gap is formed between the contact portion 22 and the restricting member 70. Therefore, when the opening operation is performed, the contact portion 22 slightly moves toward the regulating member 70, and the movement is restricted by coming into contact with the regulating member 70. The gap spacing is set so that no loud noise is generated when the contact portion 22 comes into contact with the regulating member 70. As another method for reducing the noise generated by the contact between the contact portion 22 and the regulating member 70, for example, a method of attaching a cushioning material to the regulated surface 22B of the contact portion 22 can be mentioned. This method can be combined with the setting of the gap interval described above. Examples of cushioning materials are rubber and Styrofoam.

When unlocking the lock device 1, the operation member 80 is installed at a position corresponding to the marker 90 on the second door 120. As shown in FIG. 6, when the operating member 80 installed on the second door 120 is operated upward along the second door 120, the magnetic force of the magnet 81 regulates the operating member 80 in the same direction as the moving direction of the operating member 80. The member 70 moves. As a result, the restricting member 70 moves to a place away from the contact portion 22 and the first side wall 51, and the movement of the contact portion 22 in the opening direction is not restricted by the restricting member 70. That is, the state of the lock device 1 is changed from the state of locking the door 100 to the state of unlocking the door 100. When the opening operation of the second door 120 is performed with the door 100 unlocked, the second door 120 and the regulated member 20 move in the opening direction as shown in FIG. 7, and the contact portion 22 Passes through the slit 52B of the second side wall 52 and moves to the space 50A of the box 50. As the second door 120 further moves in the opening direction, the entire regulated member 20 comes out of the box 50 and the regulated member 70 moves to the support portion 56 as shown in FIG. By moving the second door 120 from the closed position to the intermediate position, a state in which the first door 110 can be moved in the opening direction is formed.

FIG. 9 shows a case where an operation of applying a force for moving the second door 120 in the closing direction to the second door 120 (hereinafter referred to as “closing operation”) is performed while the second door 120 is moved to the intermediate position or the open position. As shown in the above, the regulated member 20 passes through the slit 51B of the first side wall 51 of the box 50 and moves to the space 50A of the box 50. The inclined surface 22A of the contact portion 22 moved to the space 50A of the box 50 comes into contact with the regulating member 70. When the regulating member 70 further moves in the closing direction, the regulating member 70 moves upward along the inclined surface 22A as shown in FIG. That is, the contact portion 22 pushes up the regulating member 70. When the regulating member 70 further moves in the closing direction from this state, the regulating member 70 rides on the top portion 22C of the contact portion 22 as shown in FIG. When the regulating member 70 further moves in the closing direction from this state, the contact portion 22 passes through the slit 52B of the second side wall 52 of the box 50 and protrudes to the outside of the second side wall 52 as shown in FIG. 12, and is regulated. The member 70 moves onto the support 56. As a result, the regulating member 70 is arranged between the contact portion 22 and the first side wall 51, and the movement of the contact portion 22 in the opening direction is restricted by the regulating member 70. That is, the state of the lock device 1 is changed from the state of unlocking the door 100 to the state of locking the door 100.

According to the lock device 1, the following actions and effects can be obtained. Since the regulating member 70 can be moved by the magnetic force of the magnet 81 of the operating member 80, it is not necessary to fix the operating member 80 to the door 100 unlike the conventional lock device installed on the door 100 with adhesive tape. Therefore, the appearance of the door 100 is maintained in a preferable state. Further, since the regulation member 70 can be operated by the operation member 80 suitable for the operation of the regulation member 70, the lock and unlock of the door 100 can be easily changed. Further, since the regulating member 70, which is a sphere, is arranged in the box 50, it is possible to prevent the regulating member 70 from falling from the second installation member 40.
