Description

  The present invention relates to a locking device used for locking an opening / closing body.

  Conventionally, a locking device using a rotating member as a locking member for locking, such as a crescent lock, has been proposed. In this type of locking device, electronic components having a power generation function and a communication function may be incorporated in order to increase the number of functions (for example, see Patent Document 1). In this case, in order to operate the electronic component, an interlocking member such as a gear that operates in conjunction with the lock member is usually incorporated.

  The lock device may be required to be downsized in a direction orthogonal to the axial direction of the rotation shaft that supports the lock member (hereinafter referred to as an axis orthogonal dimension). In addition to the electronic components described above, the locking device may incorporate a locking member that locks the locking member in the locking position. There has not yet been proposed a locking device that incorporates such a locking member or electronic component for double locking and has been reduced in size from the above viewpoint.

On the other hand, as shown in FIG. 5, the operating portion 28d of the second interlocking member 28 moves in the direction Pc2 in conjunction with the locking member 24 when the locking member 24 rotates in the unlocking direction Pb2. An external force is input to the receiving unit 30c. The electronic component 30 operates upon receiving an external force input to the input receiving units 30b and 30c. Details of the electronic component 30 will be described later.

  Returning to FIG. 2 and FIG. A part of the lock member 32 is inserted into a groove 22d formed in the side wall 22c on the front side (left side in FIG. 3) in the depth direction Y of the lock case 22. The groove 22d of the lock case 22 extends in the vertical direction.

  The lock member 32 includes a knob portion 32 a that is disposed outside the side wall portion 22 c of the lock case 22. The knob portion 32a is disposed outside the lock case 22 and is operated by the user.

  The lock member 32 has a guide portion 32 b disposed inside the lock case 22. The guide portion 32 b of the lock member 32 guides the movement of the lock member 32 by sliding the inner wall surface of the side wall portion 22 c of the lock case 22. Accordingly, the lock member 32 is supported by the side wall portion 22c of the lock case 22 so as to be slidable in the vertical direction.

  The guide portion 32b has a long shape in the sliding direction of the lock member 32, and a lock piece 32c is provided at the upper end portion thereof. The lock piece 32c is provided on the lock member 24 side in the axial direction W from the upper end portion of the guide portion 32b and on the inner side in the depth direction X from the guide portion 32b. Further, the lock piece 32 c is disposed above the rotation shaft 36.

  6 and 7 show the locking device 10 with the locking member 32 in the locked position. FIG. 6 is a view from the same viewpoint as FIG. 2, and FIG. 7 is a view from the same viewpoint as FIG. It is. The lock member 32 is movable between a lock position (see FIGS. 6 and 7) on one end side of the movable range in the sliding direction and a lock release position (see FIGS. 4 and 5) on the other end side. It is.

  As shown in FIGS. 6 and 7, when the lock member 32 is in the lock position and the lock member 24 is in the lock position, the lock piece 32 c of the lock member 32 is in contact with the contact portion 26 c of the first interlocking member 26. By hitting, the movement of the first interlocking member 26 and the lock member 24 is restricted. Thereby, the lock member 32 restrains the rotation of the lock member 24 in the unlocking direction Pb2, and locks the lock member 24 in the lock position. On the other hand, as shown in FIGS. 4 and 5, when the lock member 32 is in the unlock position, the lock piece 32 c allows the first interlocking member 26 and the lock member 24 to move, and unlocks the lock member 24. To do.

  Returning to FIG. 2 and FIG. The biasing member 34 is disposed closer to the counter-locking member than the rotation shaft 36 and the second interlocking member 28. Further, the urging member 34 is disposed on the side opposite to the locking member from the first tooth portion 26d and the abutting portion 26c of the first interlocking member 26. Further, the entire urging member 34 is disposed below the lock piece 32 c of the lock member 32. The entire urging member 34 is disposed on the opposite side of the electronic component 30 in the vertical direction Z across the lock piece 32c of the lock member 32.

  The 1st interlocking member 26 has the 1st attaching part 26e which protrudes toward the counter-locking member side from the 1st large diameter part 26b. The lock case 22 has a second attachment portion 22e that protrudes from the inner wall surface of the storage portion 22a toward the counter-locking member. The biasing member 34 of the embodiment is a tension coil spring that functions as an elastic body that can be elastically deformed. One end of the biasing member 34 is attached to the first attachment portion 26e of the first interlocking member 26, and the other end is attached to the second attachment portion 22e of the lock case 22. Thereby, the biasing member 34 can bias the lock member 24 via the first interlocking member 26.

  As shown in FIGS. 2 and 3, the biasing member 34 attaches the locking member 24 in the unlocking direction d1 when the biasing member 34 is at a position closer to the unlocking position within the movable range of the locking member 24 in the rotating direction. Rush. On the other hand, as shown in FIGS. 4 and 5, the urging member 34 attaches the locking member 24 in the locking direction d2 when the urging member 34 is in a position closer to the locking position in the movable range in the rotation direction of the locking member 24. Rush. As a result, the lock member 24 is held at the unlocked position or the locked position at both ends of the movable range in the rotation direction of the lock member 24. Thus, the urging member 34 urges the locking member 24 toward either the unlocking direction d1 or the locking direction d2 according to the rotational position of the locking member 24.

  FIG. 8 is a configuration diagram showing functional blocks of a configuration related to the electronic component 30. The electronic component 30 includes a power generation unit 30d and a communication unit 30e in addition to the plurality of input reception units 30b and 30c. Each block can be realized by various elements and circuits in hardware, and realized by a computer program or the like in software. Here, functional blocks realized by their cooperation are depicted. These functional blocks can be realized in various modes by a combination of hardware and software.

  The power generation unit 30d can generate power temporarily in response to input to the input receiving units 30b and 30c. The power generation unit 30d of the embodiment can generate power using a magnetostrictive element. Specifically, when the power generation unit 30d receives an external force input to the input receiving units 30b and 30c, the magnetostrictive element is deformed, and can temporarily generate power due to the inverse magnetostrictive effect of the magnetostrictive element.

  The communication unit 30e can communicate with the external communication device 40 triggered by input to the input receiving units 30b and 30c. The communication unit 30e of the embodiment communicates with the external communication device 40 by receiving power supply from the power generation unit 30d. The communication unit 30 e transmits state information indicating the state of the lock device 10 and ID information for specifying the lock device 10 to the external communication device 40. The state information indicates whether the lock device 10 is in the locked state or the unlocked state. The communication unit 30e according to the embodiment transmits a state signal indicating that it is in a locked state when an external force is input to the first input receiving unit 30b, and when the external force is input to the second input receiving unit 30c, A status signal indicating the locked state is transmitted.

  The external communication device 40 collects and manages information transmitted from a plurality of lock devices 10 (only one is shown in the figure). The external communication device 40 has a function of causing the display terminal 42 to display state information and ID information transmitted from the lock device 10. The display terminal 42 is an electronic device such as a computer display, a smartphone, or a tablet.

The operation of the above locking device 10 will be described.
First, as shown in FIGS. 2 and 3, the lock member 24 is moved from the unlocked position to the locked position by rotating the lock member 24 in the locking direction Pb1 in a state where the lock member 32 is disposed at the unlocked position. Consider the case of moving. In this case, the second interlocking member 28 operates in conjunction with the lock member 24, and the operating portion 28 d of the second interlocking member 28 inputs an external force to the first input receiving portion 30 b of the electronic component 30. Thereby, while the electric power generation part 30d of the electronic component 30 produces | generates electric power temporarily, the state signal which shows that it exists in a locked state is transmitted to the external communication apparatus 40 from the communication part 30e.

  Next, as shown in FIGS. 4 and 5, the lock member 24 is unlocked from the lock position by rotating the lock member 24 in the unlocking direction Pb <b> 2 in a state where the lock member 32 is disposed at the unlock position. Consider the case of moving to a position. In this case, the second interlocking member 28 operates in conjunction with the lock member 24, and the operating portion 28 d of the second interlocking member 28 inputs an external force to the second input receiving portion 30 c of the electronic component 30. Thereby, while the electric power generation part 30d of the electronic component 30 produces electric power temporarily, the state signal which shows that it exists in an unlocking state is transmitted to the external communication apparatus 40 from the communication part 30e.

  Next, as shown in FIGS. 6 and 7, a case where the lock member 32 is arranged at the lock position in a state where the lock member 24 is arranged at the lock position will be considered. In this case, when the lock member 32 is rotated in the unlocking direction Pb 2, the first interlocking member 26 operates in conjunction with the lock member 24, and the contact portion 26 c of the first interlocking member 26 locks the lock member 32. It hits the piece 32c. Thereby, the movement of the 1st interlocking member 26 and the lock member 24 is restrained, and the lock member 24 is locked to a locking position.

  FIG. 9 is a diagram illustrating a movement locus of the lock member 32. In this figure, the movement locus of the lock member 32 is hatched with a two-dot chain line. The movement locus is a locus through which the lock member 32 passes when the lock member 32 moves between the lock position and the unlock position.

  The lock piece 32c of the lock member 32 is provided so that its movement trajectory passes through a position overlapping the second interlocking member 28 in the axial direction W. This means that the movement locus of the lock member 32 is at a position shifted in the axial direction W from the second interlocking member 28. Thereby, compared with the case where the 1st interlocking member 26, the 2nd interlocking member 28, and the lock member 32 are operated on the same axis orthogonal plane, the axis orthogonal dimension of the part which they occupy can be reduced. Therefore, it is possible to reduce the axial orthogonal dimension of the lock device 10 while incorporating the lock member 32 and the electronic component 30.

  FIG. 10 is a diagram illustrating a movement locus of the abutting portion 26 c of the first interlocking member 26. In the figure, the movement locus of the abutting portion 26c is hatched with a two-dot chain line. The movement trajectory refers to a trajectory through which the abutting portion 26c of the first interlocking member 26 that operates in conjunction with the locking member 24 when the locking member 24 moves between the locking position and the unlocking position.

  The contact portion 26c of the first interlocking member 26 is provided so that the movement locus thereof passes through a position overlapping the second interlocking member 28 in the axial direction W. The abutting portion 26c is disposed at a position overlapping the second interlocking member 28 in the axial direction W when the locking member 24 is in the locking position. On the other hand, as shown in FIG. 3, when the lock member 24 is in the unlocked position, the second interlocking member 28 is disposed at a position that does not overlap with the axial direction W.

  As shown in FIG. 10, the abutting portion 26 c of the first interlocking member 26 overlaps with the guide portion 32 b that is a part of the locking member 32 in the axial direction W when the locking member 32 is in the unlocked position. It is provided to pass through the position. However, if this condition is not satisfied, in order to avoid interference between the first interlocking member 26 and the lock member 32, the first interlocking member 26 and the lock member 32 need to be separated in the depth direction X. The dimensions increase. In this regard, according to the embodiment, the axial orthogonal dimension of the portion occupied by the lock member 32 and the first interlocking member 26 can be reduced and the axial orthogonal dimension of the lock device 10 can be reduced compared to the case where the above-described conditions are not satisfied. .

The other effect of the above locking device 10 is demonstrated.
The urging member 34 is attached to the first interlocking member 26 used for locking the locking device 10. Therefore, in addition to the role used to lock the lock member 24, the first interlocking member 26 can play a role as an attachment partner of the urging member 34. For this reason, the number of parts can be suppressed rather than having these roles played by individual members, and the locking device 10 can be downsized.

  The first interlocking member 26 can rotate integrally with the rotating shaft 36, and the biasing member 34 is opposite to the lock member 24 in the axial direction W than the rotating shaft 36 and the second interlocking member 28. Placed on the side. Therefore, while avoiding interference with the rotating shaft 36 and the second interlocking member, the biasing is performed using the space opposite to the locking member 24 in the axial direction W from the rotating shaft 36 and the second interlocking member 28. The member 34 is actuated. For this reason, compared with the case where the urging member 34 is operated on the same axis orthogonal plane as the rotation shaft 36 and the second interlocking member 28, the axis orthogonal dimension of the portion occupied by them can be reduced, and the axis orthogonal dimension of the lock device 10 can be reduced. Miniaturization can be achieved.

  The lock member 32 locks the lock member 24 by coming into contact with the first interlocking member 26 as a driving member, not the second interlocking member 28 as a driven member. Therefore, when locking the lock member 24, the reaction force applied from the lock member 32 to the first interlocking member 26 is not transmitted to the power transmission path between the first interlocking member 26 and the second interlocking member 28. I'm sorry. For this reason, the burden on the site | part which comprises this power transmission path | route can be reduced, and the intensity | strength requested | required of the site | part can be reduced. In the embodiment, “parts constituting the power transmission path” refer to the first tooth portion 26 d of the first interlocking member 26 and the second tooth portion 28 c of the second interlocking member 28.

  The urging member 34 is attached to the first interlocking member 26 serving as a driving member, not the second interlocking member 28 serving as a driven member. Therefore, it is not necessary to transmit the urging force applied from the urging member 34 to the first linking member 26 to the power transmission path between the first linking member 26 and the second linking member 28. For this reason, the burden on the site | part which comprises this power transmission path | route can be reduced, and the intensity | strength requested | required of the site | part can be reduced.

  When the plurality of shojis 16 are in the fully closed position, the lock member 24 can lock the shojis 16 in cooperation with the lock catches 38 by being hooked on the lock catches 38. On the other hand, when the plurality of shojis 16 are in the open position opened from the fully closed position, the lock member 24 cannot be locked by being hooked on the lock receiver 38. Such a locking device 10 includes an emptying prevention mechanism (not shown) that locks the locking member 24 in the unlocked position when the plurality of shojis 16 are in the open position. Since this type of emptying prevention mechanism is known, only a brief description will be given here.

  The emptying prevention mechanism includes a trigger member (not shown) fixed to the lock member 24 and a trigger receiver (not shown) fixed to the lock receiver 38. The trigger member is movable between a lock position where the lock member 24 is locked in the unlock position and a lock release position where the lock is released.

  Although the rotation shaft 36 has been described as being rotatable integrally with the first interlocking member 26, it may be rotatable integrally with the second interlocking member 28. In this case, the second interlocking member 28 is a driving member, and the first interlocking member 26 is a driven member. That is, it is only necessary that one of the first interlocking member 26 and the second interlocking member 28 can drive the other. Moreover, although both the 1st interlocking member 26 and the 2nd interlocking member 28 demonstrated the example supported so that rotation to the rotating shaft 36 or the fixed shaft 38 was carried out, you may be supported so that a lock | rock is slidable.

  Although the electronic component 30 demonstrated the example which can perform both a power generation function and a communication function in response to operation | movement of the lock member 24, it may be executable at least one. Moreover, the electronic component 30 should just be able to operate | move so that an electrical function may be exhibited in response to operation | movement of the lock member 24, and the specific example of the function is not limited to a power generation function and a communication function.

  The power generation unit 30d has been described as being able to generate power using a magnetostrictive element. However, the specific example is not particularly limited as long as it can generate power upon receiving an external force input to the input receiving units 30b and 30c. For example, the power generation unit 30d may be capable of generating power using a piezoelectric element. In this case, the power generation unit 30d can generate power by receiving an external force and deforming the piezoelectric element.

  Although the communication part 30e demonstrated the example which receives supply of electric power from the electric power generation part 30d, and communicates, you may receive supply of electric power from other electric power sources, such as a battery, and may communicate.

  Generalizing the invention embodied by the above embodiments and modifications leads to the following technical idea. Hereinafter, description will be made by using aspects described in the problems to be solved by the invention.

In the first aspect, the lock device of the second aspect may include a biasing member attached to the first interlocking member and applying a biasing force to the lock member via the first interlocking member.
According to this aspect, in addition to the role used for locking the lock member, the first interlocking member can be assigned the role as the attachment partner of the biasing member, and the number of parts can be increased compared to the case where these roles are assigned to the individual members. Can be suppressed.

According to a third aspect of the locking device, in the second aspect, the first interlocking member can rotate integrally with the rotating shaft, and the biasing member is more movable than the rotating shaft. May be arranged on the opposite side of the axial direction.
According to this aspect, while avoiding interference with the rotating shaft and the second interlocking member, the biasing member is utilized by utilizing the space on the opposite side of the axial direction from the locking shaft and the second interlocking member. Can be operated. For this reason, the axis orthogonal dimension of the part which they occupy can be reduced rather than the case where an urging member is operated on the same axis orthogonal plane as a rotation axis or the 2nd interlocking member.

In any one of the first to third aspects, the locking device of the fourth aspect includes a contact portion that is applied to the locking member when the first interlocking member locks the locking member in the locking position. The abutting portion may be provided so that a movement trajectory when the lock member is in the unlock position passes through a position overlapping the lock member in the axial direction.
According to this aspect, the axial orthogonal dimension of the portion occupied by the lock member or the first interlocking member can be reduced as compared with the case where this condition is not satisfied.

In the lock device according to a fifth aspect, in any one of the first to fourth aspects, the second interlocking member is driven by the first interlocking member, and the first interlocking member rotates integrally with the lock member. You may move.
According to this aspect, when locking the locking member, it is not necessary to transmit the reaction force applied from the locking member to the first interlocking member to the power transmission path between the first interlocking member and the second interlocking member. .
