Mode for Carrying Out the Invention

[0009] Hereinafter, an example of the present disclosure will be described with reference to the accompanying drawings. The following description is merely illustrative in nature and does not limit the present disclosure, its applications, and its uses. The accompanying drawings are schematic drawings, and the illustrated configurations and actual products may have different dimensional ratios and the like.

[0010] The electromagnetic lock device 1 according to one aspect of the present disclosure includes, as shown in FIG. 1, a first lock member 10 and a second lock member 20. In this aspect, power is supplied from the power source 30 to the first lock member 10 and the second lock member 20. A switch 40 capable of switching on and off the power supply to the first lock member 10 is located between the first lock member 10 and the power source 30.

[0011] The first lock member 10 includes, for example, an electromagnet 101 and is configured as follows. · In the first on state in which power is supplied to the first lock member 10, it adsorbs to the second lock member 20 and electromagnetically locks the adsorption of the first lock member 10 to the second lock member 20. · In the first off state where no power is supplied to the first locking member 10, the electromagnetic lock of the first locking member 10 attracting to the second locking member 20 is released.

[0012] The second locking member 20 includes, for example, an electromagnetic solenoid 201 and is configured as follows. · In the second off state where no power is supplied to the second locking member 20, the adsorption state where the first locking member 10 is adsorbed to the second locking member 20 is mechanically locked. · In the second on state where power is supplied to the second locking member 20, the mechanical lock of the adsorption state where the first locking member 10 is adsorbed to the second locking member 20 is released.

[0013] For example, assume that there is no abnormality in the power supply 30 and power is supplied from the power supply 30 to the first locking member 10 and the second locking member 20. In this case, the power supply state of the first locking member 10 is switched by the switch 40. That is, by operating the switch 40, the first on state and the first off state are switched. The power supply state of the second locking member 20 is maintained in the second on state.

[0014] For example, assume that an abnormality occurs in the power supply 30 and power is no longer supplied from the power supply 30 to the first locking member 10 and the second locking member 20. In this case, the power supply state of the first locking member 10 is maintained in the first off state regardless of the operation of the switch 40. The power supply state of the second locking member 20 is maintained in the second off state.

[0015] In this aspect, as shown in FIG. 2, the first locking member 10 includes a first main body portion 11, and the second locking member 20 includes a second main body portion 21. The second main body portion 21 is configured such that the first main body portion 11 can be adsorbed. The electromagnetic lock device 1 in the adsorption state where the first locking member 10 is adsorbed to the second locking member 20 is shown in FIG. 3. In this aspect, the first main body portion 11 and the second main body portion 21 are substantially rectangular parallelepiped in shape and have substantially the same size.

[0016] The first main body portion 11 has a first opposing surface 111 that faces the second main body portion 21 in the adsorbed state, a first recess 112 provided on the first opposing surface 111, and a first connecting portion 113. The first recess 112 is recessed in a direction away from the second main body portion 21 along the opposing direction (for example, the first direction X) that faces the second main body portion 21 in the adsorbed state, and is configured such that the first connecting portion 113 is located inside thereof. The first recess 112 is configured to be able to accommodate a first driving member 214 described later.

[0017] The first connecting portion 113 has, for example, a substantially cylindrical shape extending along a direction intersecting the first direction X (for example, the direction penetrating the paper surface of FIG. 2), and is configured such that the first driving member 214 can be connected thereto (see FIG. 3).

[0018] The second main body portion 21 has a second opposing surface 211 that faces the first main body portion 11 in the adsorbed state, a second recess 212 provided on the second opposing surface 211, and a second connecting portion 213. The second recess 212 faces the first recess 112 in the adsorbed state and is recessed in a direction away from the first main body portion 11 along the first direction X, and is configured such that the second connecting portion 213 is located inside thereof in the second on state.

[0019] The second recess 212 has a receiving groove 2121 capable of accommodating a transmission member 215 described later. Taking the surface intersecting the second opposing surface 211 of the second recess 212 as the side surface 2122 and the surface facing the second opposing surface 211 of the second recess 212 as the bottom surface 2123, the receiving groove 2121 is provided at a position adjacent to the bottom surface 2123 of the side surface 2122. The receiving groove 2121 is recessed from the side surface 2122 toward the outside of the second main body portion 21.

[0020] The second connecting portion 213 is provided on the second main body portion 21 and is configured to be movable between a connection position P1 (shown in FIG. 3) and a release position P2 (shown in FIG. 2) by switching between the second on state and the second off state. The connection position P1 is a position where it is connected to the first connecting portion 113 in the adsorbed state and can restrict the movement of the second main body portion 21 with respect to the first main body portion 11. The release position P2 is a position where the connection to the first connecting portion 113 is released.

[0021] In this aspect, the second locking member 20 includes a first driving member 214 that is driven by switching between a second on state and a second off state, and a transmission member 215.

[0022] The first driving member 214 is rod-shaped and has a first end portion 216 that is one end portion in the direction in which the first driving member 214 extends, and a second end portion 217 that is the other end portion located on the side opposite to the first end portion 216 in the direction in which the first driving member 214 extends. The first end portion 216 is located inside the second recess 212 regardless of the power state of the second locking member 20, and is rotatably connected about a rotation axis 218 that extends in a direction intersecting the first direction X with respect to the second main body portion 21. The rotation axis 218 is located near the side surface 2122 provided with the accommodation groove 2121. A second connection portion 213 is located at the second end portion 217.

[0023] In this aspect, the first driving member 214 includes a first portion 2141 that extends linearly, and a second portion 2142 and a third portion 2143 that are respectively located at both ends of the first portion 2141. A rotation axis 218 is located at one end of the first portion 2141. The second portion 2142 extends from the end portion of the first portion 2141 where the rotation axis 218 is located in a direction intersecting the first portion 2141 and approaching the bottom surface 2123 of the second recess 212, and constitutes the first end portion 216. When viewed along the first direction X and the direction (for example, the second direction Z) intersecting the direction in which the rotation axis 218 extends, a part of the second portion 2142 overlaps with the accommodation groove 2121. The third portion 2143 extends from the end portion of the first portion 2141 where the rotation axis 218 is not located in a direction intersecting the first portion 2141 and in a direction opposite to the second portion 2142, and constitutes the second end portion 217.

[0024] The transmission member 215 is configured to be movable along the bottom surface 2123 of the second recess 212 in the second direction Z by switching the power state of the second locking member 20. In the second on state, the transmission member 215 is attracted by the electromagnetic solenoid 201 and located at the first position P11 (see FIG. 2). When the transmission member 215 is located at the first position P11, it is received in the receiving groove 2121 of the second recess 212 and is located between the second main body portion 21 and the first end portion 216 of the first driving member 214 in the second direction Z. In the second off state, the attraction of the electromagnetic solenoid 201 is released and the transmission member 215 is located at the second position P12 (see FIG. 3). When the transmission member 215 is located at the second position P12, it is located in the middle of the second recess 212 in the second direction Z along the bottom surface 2123 of the second recess 212. When the transmission member 215 moves from the first position P11 to the second position P12, the first end portion 216 of the first driving member 214 is pushed by the transmission member 215 in the second direction Z and in a direction away from the side surface 2122. As a result, the first driving member 214 rotates and the second connecting portion 213 moves from the release position P2 to the connection position P1.

[0025] The second connecting portion 213 has a hook shape. In this embodiment, the second connecting portion 213 is composed of a third portion 2143 of the first driving member 214 and a protruding portion 2144 protruding from the tip of the third portion 2143 toward the rotation shaft 218. The second connecting portion 213 is configured to be able to be hooked on the first connecting portion 113 when located at the connection position P1. In a state where the second connecting portion 213 is hooked on the first connecting portion 113, the movement of the second main body portion 21 with respect to the first main body portion 11 and the movement of the first main body portion 11 with respect to the second main body portion 21 are restricted, and the adsorption states of the first locking member 10 and the second locking member 20 are mechanically locked.

[0026] For example, assume that power supply from the power source 30 to the first locking member 10 and the second locking member 20 is interrupted due to an abnormality or the like. In this case, while the electromagnetic lock between the first locking member 10 and the second locking member 20 by the electromagnet 101 of the first locking member 10 is released, the energization of the electromagnetic solenoid 201 of the second locking member 20 is released. When the energization of the electromagnetic solenoid 201 is released, the second connection portion 213 moves from the release position P2 to the connection position P1, and the adsorption state of the first locking member 10 and the second locking member 20 is mechanically locked.

[0027] The electromagnetic locking device 1 can exhibit the following effects.

[0028] The electromagnetic locking device 1 includes a first locking member 10 and a second locking member 20 to which power is respectively supplied from the power source 30. In the first on state, the first locking member 10 adsorbs to the second locking member 20 and electromagnetically locks the adsorption of the first locking member 10 to the second locking member 20. In the first off state, the electromagnetic lock of the adsorption of the first locking member 10 to the second locking member 20 is configured to be released. The second locking member 20 is configured to mechanically lock the adsorption state in which the first locking member 10 is adsorbed to the second locking member 20 in the second off state, and to release the mechanical lock of the adsorption state in which the first locking member 10 is adsorbed to the second locking member 20 in the second on state. With such a configuration, even if the electromagnetic lock of the adsorption of the first locking member 10 to the second locking member 20 is released due to an abnormality of the power source 30 or the like, the adsorption state of the first locking member 10 and the second locking member 20 can be maintained by mechanical locking. As a result, it is possible to realize the electromagnetic locking device 1 that can maintain the locked state even when the power supply stops during locking.

[0029] The first lock member 10 includes a first main body portion 11 having a first connection portion 113. The second lock member 20 includes a second main body portion 21 to which the first main body portion 11 can be adsorbed and a second connection portion 213. The second connection portion 213 is provided on the second main body portion 21 and is configured to be movable between a connection position P1 and a release position P2 by switching between a second on state and a second off state. With such a configuration, the electromagnetic lock device 1 that can maintain the locked state even when the power supply stops during locking can be more reliably realized.

[0030] The first main body portion 11 includes a first opposing surface 111 that faces the second main body portion 21 in the adsorbed state. The first opposing surface 111 is recessed in a direction away from the second main body portion 21 along the opposing direction that faces the second main body portion 21 in the adsorbed state, and has a first recess 112 in which the first connection portion 113 is located inside. The second main body portion 21 includes a second opposing surface 211 that faces the first main body portion 11 in the adsorbed state. The second opposing surface 211 is recessed in a direction away from the first main body portion 11 along the opposing direction that faces the first recess 112 in the adsorbed state, and has a second recess 212 in which the second connection portion 213 is located inside in the second on state. With such a configuration, the electromagnetic lock device 1 that can maintain the locked state even when the power supply stops during locking can be more reliably realized.

[0031] The second lock member 20 includes a rod-shaped first driving member 214 that is driven by switching between a second on state and a second off state. One end portion 216 of the first driving member 214 in the direction in which the first driving member 214 extends is located inside the second recess 212 and is rotatably connected around a rotation axis 218 that extends in a direction intersecting the opposing direction with respect to the second main body portion 21. The second connection portion 213 is located at the other end portion 217 in the direction in which the first driving member 214 extends. The second connection portion 213 has a hook shape. The first connection portion 113 is configured to be able to be hooked when the second connection portion 213 is located at the connection position P1. With such a configuration, the electromagnetic lock device 1 that can maintain the locked state even when the power supply stops during locking can be more reliably realized.

[0032] The electromagnetic lock device 1 can be configured as follows.

[0033] The mechanical lock in the adsorbed state where the first lock member 10 is adsorbed to the second lock member 20 is not limited to the above aspect. For example, the configurations shown in FIGS. 4 to 11 can be adopted. Thus, the first connection portion 113 and the second connection portion 213 can adopt various configurations according to the design of the electromagnetic lock device 1 and the like. As a result, an electromagnetic lock device 1 that can maintain the locked state even when the power supply stops during locking can be more surely realized.

[0034] In the electromagnetic lock device 1 shown in FIGS. 4 and 5, the first connection portion 113 is constituted by the first protrusion 12, and the second connection portion 213 is constituted by the second protrusion 22. As an example, the first main body portion 11 and the second main body portion 21 have a substantially rectangular parallelepiped shape. The second main body portion 21 is larger than the first main body portion 11. The first protrusions 12 are respectively provided on both surfaces of the first main body portion 11 in the third direction Y. The second drive members 222 are respectively provided on both surfaces of the second main body portion 21 in the third direction Y.

[0035] The first protrusion 12 has a substantially cylindrical shape and extends in a direction (for example, the third direction Y) intersecting the first direction X in the adsorbed state from the outer surface of the first main body portion 11. The second lock member 20 has a second drive member 222 provided rotatably about a rotation axis 221 extending in the third direction Y with respect to the second main body portion 21 on the outer surface of the second main body portion 21. The second drive member 222 has a substantially rectangular plate shape, one end in its longitudinal direction is connected to the rotation axis 221, and the second protrusion 22 is located at the other end in its longitudinal direction. The second protrusion 22 extends in the radial direction with respect to the rotation axis 218 from the second drive member 222. In the second on state, the second drive member 222 is located in a state of extending along a direction (for example, the second direction Z) intersecting the first direction X and the third direction Y (see FIG. 4), and in the second off state, it contacts the first protrusion 12 and the second protrusion 22 is in a state of being caught by the first protrusion 12 (see FIG. 5).

[0036] The second main body portion 21 has therein an electromagnetic solenoid 201 and a transmission member (not shown) connected to the rotating shaft 221. In the electromagnetic locking device 1 shown in FIGS. 4 and 5, by switching the energization state of the electromagnetic solenoid 201 (in other words, the second on state and the second off state), the rotating shaft 221 rotates via the transmission member. Thereby, the position of the second connection portion 213 (that is, the second protrusion portion 22) is switched from the connection position P1 to the release position P2, or from the release position P2 to the connection position P1.

[0037] In the electromagnetic locking device 1 shown in FIGS. 6 and 7, the first connection portion 113 is constituted by the groove portion 13, and the second connection portion 213 is constituted by the third protrusion portion 231. As an example, the first main body portion 11 and the second main body portion 21 have a substantially cylindrical shape. Of both ends of the first main body portion 11 in the first direction X in the adsorbed state, the end portion on the side where the first opposing surface 111 is located has a tapered shape. The second main body portion 21 is larger than the first main body portion 11, and the second opposing surface 211 is larger than the first opposing surface 111.

[0038] The groove portion 13 is located on the outer surface of the first main body portion 11 and is configured to be able to accommodate the third protrusion portion 231 in the adsorbed state. As an example, the groove portion 13 extends over the entire circumference of the outer surface of the first main body portion 11.

[0039] The second locking member 20 has a third driving member 24 housed inside the second locking member 20, and the claw portion 23 extends from the third driving member 24 in the first direction X. The third driving member 24 has a substantially cylindrical shape and is configured to be movable in the first direction X in the adsorbed state by switching between the second on state and the second off state. As a result, the position of the second connecting portion 213 (that is, the third protrusion portion 231) is switched from the connection position P1 to the release position P2, or from the release position P2 to the connection position P1. The second opposing surface 211 of the second main body portion 21 has a through hole 2111 that connects the inside and the outside of the second main body portion 21. The claw portion 23 is housed in the through hole 2111. The second connecting portion 213 is located at the tip of the claw portion 23. In the electromagnetic locking device 1 of FIGS. 6 and 7, the second locking member 20 has a plurality of claw portions 23 that are equally spaced along the circumferential direction of the third driving member 24. The second opposing surface 211 is provided with the same number of through holes 2111 as the claw portions 23.

[0040] In the second on state, the second connecting portion 213 is located inside the second main body portion 21 (see FIG. 6), and in the second off state, the second connecting portion 213 is located in a state of being caught by the groove portion 13 outside the second main body portion 21 (see FIG. 7). The claw portion 23 faces the first main body portion 11 in a direction intersecting the first direction X in the adsorbed state (for example, the radial direction with respect to the central axis L of the third driving member 24). The claw portion 23 is, as an example, in a substantially rectangular plate shape and is configured to be elastically deformable toward the outside in the radial direction with respect to the central axis L.

[0041] The third protrusion portion 231 is located at the tip of the claw portion 23 and extends from the claw portion 23 toward the first main body portion 11 in the adsorbed state.

[0042] In the electromagnetic locking device 1 shown in FIGS. 8 and 9, the first connecting portion 113 is constituted by the first recess 112, and the second connecting portion 213 is constituted by the second moving member 252. As an example, the first main body portion 11 has a substantially rectangular parallelepiped shape. The second main body portion 21 has a substantially L-shaped three-dimensional shape. The first opposing surface 111 and the second opposing surface 211 have substantially the same size. The first locking member 10 in the adsorbed state is shown by a dotted line in FIG. 8.

[0043] As shown in FIG. 9, the second locking member 20 includes a first moving member 251 and a second moving member 252. The first moving member 251 is located inside the second main body portion 21 and is configured to be movable along a direction (for example, the second direction Z) intersecting the first direction X by switching between the second on state and the second off state. Thereby, the position of the second connecting portion 213 (that is, the second moving member 252) is switched from the connection position P1 to the release position P2 or from the release position P2 to the connection position P1. As an example, the second main body portion 21 has an accommodating portion 2101 extending along the second direction Z inside thereof and capable of accommodating the first moving member 251. The second recess 212 is formed by a through hole connecting the outside of the second main body portion 21 and the accommodating portion 2101. The first recess 112 has substantially the same size as the second recess 212.

[0044] The second moving member 252 is located in the second recess 212 in the second on state and is located across the first recess 112 and the second recess 212 in the second off state (see FIG. 9). As an example, the second moving member 252 is configured to be located across the second recess 212 and the accommodating portion 2101 in the second on state (shown by a dotted line in FIG. 9).

[0045] In the electromagnetic locking device 1 shown in FIGS. 10 and 11, the first connecting portion 113 is constituted by the fourth protrusion 14, and the second connecting portion 213 is constituted by the third moving member 26. As an example, the first main body portion 11 and the second main body portion 21 have a substantially rectangular parallelepiped shape. The second main body portion 21 is larger than the first main body portion 11. The first locking member 10 in the adsorbed state is shown by a dotted line in FIG. 10.

[0046] The fourth protrusion 14 extends along the first direction X from the first facing surface 111 of the first main body 11 and is configured to be accommodated in the third recess 27 of the second main body 21 in the adsorbed state. The third recess 27 is provided on the second facing surface 211 of the second main body 21 and is recessed in a direction away from the first main body 11 along the first direction X in the adsorbed state. As an example, the fourth protrusion 14 has a substantially cylindrical shape and has a groove 141 at its tip. The groove 141 extends across the entire outer circumference of the fourth protrusion 14. The second main body 21 has a housing portion 2102 inside thereof that extends along the second direction Z and can accommodate the third moving member 26. The third recess 27 has a substantially circular opening and is connected to the housing portion 2102 inside the second main body 21.

[0047] The third moving member 26 is located inside the second main body 21 and is configured to be movable along a direction (for example, the second direction Z) intersecting the first direction X by switching between the second on state and the second off state. Thereby, the position of the second connecting portion 213 (that is, the third moving member 26) is switched from the connection position P1 to the release position P2 or from the release position P2 to the connection position P1. As an example, the third moving member 26 has a substantially rectangular plate shape, and one end thereof is configured to be fitted into the groove 141 of the fourth protrusion 14. In the second on state, the third moving member 26 is positioned in a state where it does not overlap with the third recess 27 when viewed along the first direction X (an example is shown by a dotted line in FIG. 11), and in the second off state, one end thereof is positioned in a state where it can be fitted into the groove 141 of the fourth protrusion 14 (see FIG. 11).
