Description

[Technical Field]

[0001] The present disclosure relates to a lock status detection device. [Background technology]

[0002] Conventionally, a locking state detection device that is attached to the frame material of a sliding door or sliding window and detects the locking state of a crescent lock has been known, as in Patent Document 1. In this specification, sliding doors and sliding windows are also collectively referred to as "sliding opening and closing members." [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-157496 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in Patent Document 1, the knob linked to the rotation of the crescent lock knob can be rotated to the locked position not only when the sliding door is closed but also when the sliding door is open. Therefore, even when the sliding door is open, the interlocking member slides when the crescent lock knob is rotated, resulting in the transmission of a locking signal. In other words, the locking signal is transmitted even when the connecting part of the crescent lock and the lock catch are not connected, i.e., in a so-called "idle" state.

[0005] The present disclosure has been made in consideration of the above, and provides a technology that can prevent a locking signal from being transmitted when a crescent lock is in an idle state. [Means for solving the problem]

[0006] The locking status detection device of the first aspect of the present disclosure is a locking status detection device that detects the locked position of a knob of a crescent lock provided on the frame material of a sliding opening / closing member and transmits a locking completion signal, and includes: a block member that is provided on the frame material and prevents the knob from moving to the locked position when in a locked state; an unlocking member that locks the block member when the sliding opening / closing member is not closed and releases the locked state of the block member when the sliding opening / closing member is closed; and a transmitting unit that transmits the locking completion signal when the knob moves the block member to the locked position.

[0007] In the locking status detection device of the first aspect, a block member is provided on the frame of the sliding door member. When the block member is locked by the unlocking member, it prevents the knob of the crescent lock provided on the frame member from moving to the locked position. When the sliding door member is closed, the unlocking member releases the locking state of the block member, allowing the knob to move to the locked position. Furthermore, when the knob moves the block member to the locked position, a locking completion signal is transmitted from the transmitting unit, eliminating the need for visual confirmation of locking. In this way, by preventing the knob from moving to the locked position unless the sliding door member is closed, it is possible to prevent the transmission of a locking signal when the crescent lock is in an unlatched state.

[0008] A locking status detection device of a second aspect of the present disclosure is the locking status detection device of the first aspect, wherein the block member is slidably arranged in a housing attached to a frame material, and is slidable between a first position that prevents the knob from moving to the locked position, and a second position that is pressed by the knob to move the knob to the locked position and cause the transmitter to transmit a locking completion signal.

[0009] In the locking state detection device of the second aspect, the block member is simply disposed in the housing, and the block member can slide between the first position and the second position. This mechanical structure allows the block member to be moved with the knob, eliminating the need for an electrical mechanism.

[0010] A locking state detection device of a third aspect of the present disclosure is the locking state detection device of the second aspect, wherein the block member is biased toward the first position by a first spring member.

[0011] In the locking state detection device of the third aspect, the biasing force of the first spring member allows the block member to slide between the first position and the second position, resulting in a simple structure of the locking state detection device.

[0012] A locking status detection device of a fourth aspect of the present disclosure is the locking status detection device of the second or third aspect, wherein the unlocking member is a lever that is swingably arranged within the housing and is swingable between a locked position in which it abuts against the block member to lock the block member at the first position, and an unlocked position in which it moves away from the block member to allow the block member to move to the second position.

[0013] In the locking state detection device of the fourth aspect, the unlocking member is configured as a lever that is swingably mounted within the housing, which allows the unlocking member to be stored more compactly within the housing compared to when the unlocking member is a slide mechanism.

[0014] A locking status detection device of a fifth aspect of the present disclosure is the locking status detection device of the fourth aspect, wherein one end of the lever is biased toward the locked position by a second spring member, is slidably mounted on the housing, and has a contact portion that is pushed toward the other end of the lever and protrudes from the housing, and has a sliding member that pushes back the other end of the lever when the contact portion is pushed into the sliding opening / closing member, causing the lever to swing to the unlocked position.

[0015] In the locking status detection device of the fifth aspect, the lever is biased toward the locked position by a single second spring member, and as a result, the sliding member can be held in a position where the abutting portion is pressed into the sliding member. This eliminates the need for an electrical mechanism, such as a motor, to swing the lever.

[0016] A locking state detection device of a sixth aspect of the present disclosure is the locking state detection device of the fifth aspect, wherein a block is attached to the sliding opening and closing member, which contacts the contact portion of the sliding member and adjusts the amount of depression.

[0017] In the locking status detection device of the sixth aspect, even if various sliding opening / closing members have different standards, by attaching a block to the sliding opening / closing member, when the sliding opening / closing member is closed, the block will come into contact with the contact portion and the lever will be swung to the unlocked position.

[0018] A locking status detection device of a seventh aspect of the present disclosure is a locking status detection device of any of the first to sixth aspects, wherein the transmitter comprises a magnet provided on the block member and a transmitter that transmits the locking completion signal when the magnet approaches and detects a magnetic force greater than a predetermined value.

[0019] In the locking state detection device of the seventh aspect, the abutment switch can be used to make the transmitter transmit the locking completion signal with fewer malfunctions compared to a system in which the transmitter transmits the locking completion signal.

[0020] A locking state detection device of an eighth aspect of the present disclosure is the locking state detection device of the seventh aspect, wherein the locking completion signal transmitted from the transmitter includes position information of the sliding opening / closing member.

[0021] In the locking state detection device of the eighth aspect, the position of the sliding opening and closing member from which the locking completion signal is transmitted is detected, thereby facilitating the task of checking whether the door is locked.

[0022] A locking status detection device of a ninth aspect of the present disclosure is the locking status detection device of the eighth aspect, wherein the locking completion signal transmitted from the transmitter can be confirmed by a receiver owned by a manager.

[0023] In the locking status detection device of the ninth aspect, the manager can use a receiver at hand to detect the sliding door member that has transmitted the locking completion signal. This makes it easier to share the task of checking whether the door is locked compared to a system where centralized management is performed in a management room. [Effects of the Invention]

[0024] According to the present disclosure, it is possible to prevent the transmission of a locking signal when the crescent lock is in an idle state. [Brief explanation of the drawings]

Mode for Carrying Out the Invention

[0026] This embodiment will be described below. In the following description of the drawings, identical or similar parts are designated by the same or similar reference numerals. However, the drawings are schematic, and the relationship between thickness and planar dimensions, the thickness ratio of each device or component, etc., differ from the actual ones. Therefore, specific thicknesses and dimensions should be determined with reference to the following description. Furthermore, parts with different dimensional relationships and ratios are included between the drawings. Furthermore, unless otherwise specified in the specification, the number of each component element of the present disclosure is not limited to one, and multiple elements may be present.

[0027] <Structure of the lock status detection device> First, the structure of the lock status detection device 10 according to this embodiment will be described. As shown in Figures 1(A) and 1(B), the lock status detection device 10 has a housing 11, a block member 12, an unlocking member 14, and a transmitting unit 16 (see Figure 16). As shown in Figure 7, the lock status detection device 10 detects the locked position of the knob 22A of the crescent lock 22 provided on the frame material 20A of the sliding opening and closing member 20, and transmits a locking completion signal.

[0028] In the lock status detection device 10 of this embodiment, the components other than the transmitter 16 can be molded from, for example, resin. Note that in the present disclosure, the material of the lock status detection device is not limited to this, and any material such as metal or wood can be used.

[0029] (housing) The housing 11 is box-shaped. As shown in FIGS. 1(C), 1(D), and 1(E), an opening 11A is provided on the left side surface of the housing 11. A contact portion 17B of a rod-shaped slide member 17 disposed inside the housing 11 is exposed to the outside from the opening 11A. The housing 11 in this embodiment is hexagonal, but in the present disclosure, the shape of the housing is not limited to this and can be changed as appropriate.

[0030] The abutment portion 17B is a rolling wheel rotatably attached to the end of the slide member 17. Therefore, as shown in Fig. 5, which will be described later, even if the surface of the frame material 20A of the sliding opening and closing member 20 abuts against the rolling wheel of the abutment portion 17B, the frame material 20A moves smoothly and is not easily broken. When a force is applied inward from the frame material 20A via the abutment portion 17B, the abutment portion 17B is pushed into the inside of the housing 11.

[0031] As shown in FIG. 1(F), an opening 11A is provided on the right side of the housing 11, similar to the left side. In this embodiment, the abutment portion 17B is not exposed from the opening 11A on the right side of the housing 11, but in the present disclosure, the abutment portion 17B may be exposed from the opening 11A on the right side of the housing 11 depending on the specifications of the sliding door member. In other words, the end of the sliding member 17 only needs to be provided on at least one of the left and right sides of the sliding member 17. The locking state detection device is highly versatile, as it can be applied to sliding door members of different specifications.

[0032] In the present disclosure, it is not essential that the contact portion 17B be a rolling wheel. Furthermore, it is not essential that the contact portion 17B be provided. In the present disclosure, the slide member 17 may have an end portion that protrudes outside the housing 11.

[0033] As shown in FIG. 1(B), the housing 11 has a support portion 11C extending from a case portion 11F, which is the main body located on the upper side UR, to a lower side LR. The tip of the support portion 11C is hook-shaped and protrudes from the front side FR toward the rear side RR of the housing 11 in the horizontal direction. That is, the support portion 11C is L-shaped. In this embodiment, one support portion 11C is provided on each of the left side LS and the right side RS, but in the present disclosure, the number of support portions may be one, two or more, or any multiple number.

[0034] (Block material) As shown in Figures 1(A) to 1(F), the block member 12 is box-shaped. In this embodiment, the block member 12 is hexagonal, but in the present disclosure, the shape of the block member is not limited to this and can be changed as appropriate. As shown in Figure 1(B), two vertical grooves 12C extending parallel to each other in the vertical direction are formed on the back surface of the block member 12. Note that in the present disclosure, the number and shape of the vertical grooves 12C can be changed as appropriate.

[0035] The tip of the hook-shaped support portion 11C of the housing 11 fits into the upper portion of the vertical groove 12C of the block member 12. In this embodiment, the width of the support portion 11C measured along the horizontal direction and the width of the vertical groove 12C measured along the horizontal direction are slightly different from each other, which allows the housing 11 and the block member 12 to slide smoothly relative to each other.

[0036] In the present disclosure, the configuration for achieving sliding between the housing 11 and the block member 12 is not limited to the engagement between the support portion 11C and the vertical groove 12C. The sliding between the housing 11 and the block member 12 may be achieved by other means, such as an electric motor.

[0037] The block member 12 is slidable between a first position P1 (see FIG. 8) that prevents the knob 22A from moving to the locked position, and a second position P2 (see FIG. 10) that causes the transmitter 16 to transmit a locking completion signal. The block member 12 in FIG. 1(B) is disposed at the first position P1.

[0038] 8 and 11, a gap G is formed between the block member 12 disposed at the first position P1 and the housing 11 spaced apart from the block member 12. FIG. 11 illustrates a state in which a stopper portion 14C at the lower end of the unlocking member 14 disposed on the rear side of the housing 11 is fitted into the gap G. Therefore, the sliding of the housing 11 and the block member 12 is prevented by the unlocking member.

[0039] The sliding of the housing 11 and the block member 12 is controlled by the block member 12. The unlocking member 14 illustrated in Figures 8 and 11 is disposed at a locking position PR where it abuts against the block member 12 to lock the block member 12 at the first position P1.

[0040] (Unlocking member) As shown in Fig. 2, the unlocking member 14 is a rod-shaped lever extending in the vertical direction. The unlocking member 14 has a stopper portion 14C as one end, a protrusion 14E as the other end, a cylindrical connecting portion 14B provided between the stopper portion 14C and the protrusion 14E, and an abutting portion 14A provided between the connecting portion 14B and the stopper portion 14C. A through-hole 14D is formed inside the connecting portion 14B. The abutting portion 14A abuts against the slide member 17.

[0041] A cylindrical shaft 11D (see FIG. 16) provided inside the housing 11 is inserted into the through-hole 14D. An axis C of the cylindrical shaft 11D extends in the left-right direction substantially parallel to the rod-shaped slide member 17. The cylindrical shaft 11D allows the unlocking member 14 to swing within the housing 11. The unlocking member 14 swings between a locked position PR and an unlocked position PF (see FIG. 12) where the unlocking member 14 separates from the block member 12 and allows the block member 12 to move to the second position P2.

[0042] As shown in Figure 14, the abutment portion 14A at the left end of the unlocking member 14 has an inclined surface 14A1 that faces the abutment portion 17A at the right end of the slide member 17. The inclined surface 14A1 of the abutment portion 14A extends upward in Figure 14 (i.e., toward the front side FR) from the left side LS, which is the abutment portion 17B side in Figure 14, toward the right side RS, which is the unlocking member 14 side. In other words, the width of the abutment portion 14A of the unlocking member 14 measured along the front-to-rear direction in Figure 14 increases from the left side LS, which is the abutment portion 17B side, toward the right side RS, which is the unlocking member 14 side.

[0043] By interlocking with the slide member 17, the unlocking member 14 releases the locked state of the block member 12 when the sliding opening and closing member 20 is closed. That is, the unlocking member 14 of this embodiment not only creates a state in which the block member 12 is allowed to slide, but also creates a state in which the block member 12 is prevented from sliding. In this embodiment, the interlocking of the unlocking member 14 and the slide member 17 switches between a state in which the block member 12 is allowed to slide and a state in which the block member 12 is prevented from sliding.

[0044] (Sliding member) 2 and 14, the slide member 17 is a rod-shaped member extending in the left-right direction. FIG. 14 illustrates a state in which the slide member 17 is slidably supported inside the housing 11. As shown in FIG. 14, the slide member 17 has an abutment portion 17A provided on one end side and an abutment portion 17B provided on the other end side. The abutment portion 17A abuts against the unlocking member 14.

[0045] The contact portion 17A at the right end of the slide member 17 in Fig. 14 has an inclined surface 17A1 that faces the contact portion 14A of the unlocking member 14. The inclined surface 17A1 of the contact portion 17A extends from the left side, which is the contact portion 17B side in Fig. 14, to the right side, which is the unlocking member 14 side, and then extends upward in Fig. 14 (i.e., toward the front side FR).

[0046] In other words, the width measured in the front-to-rear direction of the contact portion 17A at the right end of the slide member 17 in Fig. 14 narrows from the left side LS, which is the contact portion 17B side, to the right side RS, which is the unlocking member 14 side. Fig. 14 illustrates the maximum contact width W1 in the area of ​​the contact portion 17A of the slide member 17 that contacts the unlocking member 14 when the unlocking member 14 is positioned in the locked position PR.

[0047] (First spring member) 16, a recess 12A that opens toward the housing 11 is provided in the upper part of the block member 12. One end (lower end in FIG. 16) of the first spring member 13 abuts against the recess 12A. The other end (upper end in FIG. 16) of the first spring member 13 is fitted into a protrusion 11B that is provided inside the housing 11 and protrudes downward, and comes into contact with the area surrounding the protrusion 11B of the housing 11.

[0048] In this embodiment, the first spring member 13 is a coil spring or the like, but the present disclosure is not limited to this and can be changed as desired to, for example, a leaf spring, etc. The first spring member 13 biases the block member 12, thereby biasing the block member 12 toward the first position P1, which is the lower side of the housing 11.

[0049] (Second spring member) 16, the lever of the unlocking member 14 has a protrusion 14E located above the connecting portion 14B. One end (the right end in FIG. 16) of the second spring member 15 abuts against the protrusion 14E. A recess 11E that opens toward the unlocking member 14 is provided on the inner side wall of the housing 11. The other end (the left end in FIG. 16) of the second spring member 15 is fixed to the housing 11 by fitting into the inside of the recess 11E.

[0050] In this embodiment, the second spring member 15 is a coil spring or the like, but the present disclosure is not limited to this and can be arbitrarily changed, for example, to a leaf spring or the like. The second spring member 15 biases the protrusion 14E, which biases the protrusion 14E of the lever of the unlocking member 14 toward the locked position PR, i.e., toward the rear side, which is the right side in FIG. 16 . As a result, the stopper portion 14C of the lever of the unlocking member 14 is biased so as to fit into the gap G. Furthermore, the biased unlocking member 14 abuts against the block member 12, thereby realizing the locked state of the block member 12.

[0051] (Sending Department) 16, the transmitting unit 16 includes a magnet 16A provided in the block member 12, and a transmitter 16B. The magnet 16A is disposed inside the block member 12. The transmitter 16B is disposed inside the housing 11.

[0052] When the magnet 16A approaches and detects a magnetic force equal to or greater than a predetermined value, the transmitter 16 transmits a locking completion signal. When the knob 22A moves to the locked position while moving the block member 12, a state in which the sliding of the block member 12 is permitted is formed, the transmitter 16 can transmit the locking completion signal to an external administrator.

[0053] In other words, when the sliding of the block member 12 is obstructed, the locking completion signal is not transmitted. When the locking completion signal is not transmitted, it can be detected that the sliding opening / closing member 20 is unlocked. Note that in the present disclosure, a signal may be transmitted to notify that the sliding opening / closing member 20 is unlocked.

[0054] The locking completion signal transmitted from transmitter 16B includes position information of sliding opening / closing member 20. The locking completion signal transmitted from transmitter 16B can be confirmed, for example, by a receiver owned by the manager. The receiver can be, for example, a smartphone with a predetermined application installed, or a personal computer with a predetermined browser.

[0055] In the present embodiment, the transmitter 16 uses the magnet 16A to detect the approach of the block member 12, but in the present disclosure, the means for detecting the approach of the block member 12 is not limited to this. In the present disclosure, a detection means using electricity, light, or the like may be used as the means for detecting the approach of the block member 12.

[0056] <How to use the lock status detection device> Next, a method of using the lock status detection device 10 according to this embodiment will be described. First, as shown in Fig. 3, the block member 12 of the lock status detection device 10 is provided on the frame material 20A of the sliding opening / closing member 20 via the housing 11. The housing 11 can be attached to the frame material 20A using, for example, an adhesive so that the back side RR faces the end face of the frame material 20A located opposite the window 20B.

[0057] The block member 12 is disposed in the housing 11 so as to be slidable in conjunction with the rotation of the knob 22A of the crescent lock 22. Figure 4 shows the block member 12 in a locked state. In the locked state, the block member 12 prevents the knob 22A from moving to the locked position. The unlocking member 14 keeps the block member 12 in a locked state when the sliding opening / closing member 20 is not closed.

[0058] Next, as shown in Fig. 5, with the sliding opening / closing member 20 in the closed state, for example, a user rotates the knob 22A, which serves as the opening / closing lever, to the locked position. As a result, the arc-shaped connecting portion 22B rotates from the unlocked position to the locked position, which is the position of the lock receiver 22C. In Fig. 5, the frame member 20A of the sliding opening / closing member 20 that abuts against the abutment portion 17B is illustrated by a dashed line.

[0059] (Interlocking of the unlocking member and the sliding member) 9, the slide member 17 is pushed into the housing 11 (i.e., the right side RS) by the abutment portion 17B coming into contact with the frame material 20A of the sliding opening and closing member 20. Inside the housing 11, the abutment portion 17A of the slide member 17 pushes the abutment portion 14A of the lock release member 14 toward the rear side RR against the biasing force of the first spring member 13 that biases the protrusion 14E of the lock release member 14.

[0060] When the abutment portion 17B protruding from the housing 11 is pushed into the inside of the housing 11, the abutment portion 17A located on the opposite side of the abutment portion 17B of the slide member 17 abuts against the abutment portion 14A of the lock release member 14 in FIG.

[0061] The inclined surface 17A1 of the abutting portion 17A of the slide member 17 abuts against the inclined surface 14A1 of the abutting portion 14A of the unlocking member 14, and the greater the sliding distance of the abutting portion 17A of the slide member 17, the greater the thickness of the abutting portion 17A that comes into contact with the abutting portion 14A of the unlocking member 14. As a result, the abutting portion 14A of the unlocking member 14 moves toward the rear side.

[0062] As the contact portion 14A moves toward the rear side, the unlocking member 14 swings from the locked position PR to the unlocked position PF around the axis C (see FIG. 2) of the through-hole 14D. That is, as shown in FIG. 16, the stopper portion 14C at the bottom end of the unlocking member 14 rotates so as to move away from the gap G, and the other end side is pushed back.

[0063] 15 illustrates the maximum contact width W2 within the area of ​​the contact portion 17A of the slide member 17 that contacts the unlocking member 14 when the unlocking member 14 is positioned at the unlocked position PF. Then, the stopper portion 14C of the unlocking member 14 moves away from the block member 12. FIG. 17 illustrates the state in which the stopper portion 14C moves away from the gap G between the block member 12 and the housing 11.

[0064] Then, as shown in Fig. 6, for example, when the user pushes up the knob 22A with his or her finger, the arc-shaped connecting portion 22B further rotates from the unlocked position to the locked position. This connects the connecting portion 22B and the lock receiver 22C. Furthermore, when the rotating knob 22A is pushed from the lower side LR, the block member 12 slides toward the upper side UR in Fig. 6. In other words, as shown in Fig. 7, when the sliding opening / closing member 20 is closed, the block member 12 moves the knob 22A to the locked position by sliding toward the upper side UR.

[0065] 9 and 10, the block member 12 slides by the height of the gap G, whereby the upper end of the block member 12 abuts against the lower end of the housing 11. As shown in Fig. 13, the tip of the support portion 11C of the housing 11 slides inside the vertical groove 12C of the block member 12, and moves to the lower side LR. Fig. 18 illustrates a state in which the upper part of the block member 12 is positioned in the gap G formed between the block member 12 and the housing 11.

[0066] The locked state is established by the connection of the connecting portion 22B and the lock receiver 22C. In the locked state, the sliding opening / closing member 20 is closed and cannot be moved diagonally between the upper right and lower left in FIG. 7. The closed state of the sliding opening / closing member 20 is detected when the magnet 16A approaches the transmitter 16B due to the sliding of the block member 12. Then, the transmitter 16B of the transmitter 16 of the lock state detection device 10 transmits a locking completion signal.

[0067] (Action and effect) In the locking state detection device 10 according to this embodiment, a block member 12 is provided on a frame member 20A of a sliding opening / closing member 20. When the block member 12 is locked by an unlocking member 14, it prevents a knob 22A of a crescent lock 22 provided on the frame member 20A from moving to the locked position. When the sliding opening / closing member 20 is closed, the unlocking member 14 releases the locked state of the block member 12, allowing the knob 22A to move to the locked position.

[0068] Furthermore, when the knob 22A moves the block member 12 to the locked position, a locking completion signal is transmitted from the transmitter 16, eliminating the need for visual confirmation of locking. In this way, by making it impossible to move the knob 22A to the locked position unless the sliding opening / closing member 20 is closed, it is possible to prevent transmission of a locking signal when the crescent lock 22 is in an idle state.

[0069] In this embodiment, when the knob 22A moves the block member 12 to the locked position, the transmitter 16 transmits a locking completion signal. Therefore, the locked state can be detected even from a location distant from the sliding opening / closing member 20.

[0070] In this embodiment, the locking completion signal can be transmitted to an application installed on the facility manager's smartphone, which serves as a receiver. The facility manager can remotely check the lock status of all windows where the device is installed using his or her smartphone, eliminating the need to go to the site and visually check the lock status of each window.

[0071] Therefore, when the facility manager is locking the doors at the end of the day, for example, he or she only needs to go to the windows in the classroom that have not yet sent a locking completion signal, thereby reducing the burden of patrolling to check the locking status.

[0072] Furthermore, in this embodiment, one locking state detection device 10 can achieve both the function of detecting the open / closed state of the sliding opening / closing member 20 and the function of detecting the rotational position of the knob 22A of the crescent lock 22. In other words, only one locking state detection device 10 is required to be provided for one sliding opening / closing member 20.

[0073] This reduces the cost burden compared to when a means for detecting the open / close state of the sliding opening / closing member 20 and a means for detecting the rotational position of the knob 22A of the crescent lock 22 are separately provided for one sliding opening / closing member 20. In addition, the burden of various tasks such as installation and maintenance can be reduced.

[0074] Furthermore, in this embodiment, the block member 12 can slide between the first position P1 and the second position P2 with a simple configuration in which the block member 12 is disposed in the housing 11. This mechanical structure allows the block member 12 to be moved by the knob 22A, eliminating the need for an electrical mechanism.

[0075] In addition, in this embodiment, the biasing force of the first spring member 13 allows the block member 12 to slide between the first position P1 and the second position P2, resulting in a simple structure of the locking state detection device 10.

[0076] In addition, in this embodiment, the unlocking member 14 is configured as a lever that is swingably mounted within the housing 11, so that it can be stored more compactly within the housing 11 compared to when the unlocking member is a sliding mechanism.

[0077] Furthermore, in this embodiment, the lever of the unlocking member 14 is biased toward the lock position PR by one second spring member 15, and as a result, the slide member 17 can be held in a position where the abutting portion 17B is pressed into the sliding opening and closing member 20. This eliminates the need for an electrical mechanism, such as a motor, to swing the lever.

[0078] In addition, in this embodiment, the magnetic force of the magnet 16A is detected and the locking completion signal is transmitted from the transmitter 16B. Therefore, compared to a system in which the locking completion signal is transmitted from the transmitter 16B using a contact-type switch, there are fewer malfunctions and the locking completion signal can be transmitted from the transmitter 16B.

[0079] In addition, in this embodiment, the position of the sliding opening and closing member 20 from which the locking completion signal is transmitted is detected, which facilitates the task of checking whether the door is locked.

[0080] In addition, in this embodiment, the manager can detect the sliding opening / closing member 20 that has transmitted the locking completion signal using a receiver such as a smartphone, which makes it easier to share the task of checking whether the door is locked compared to a system in which centralized management is performed in a management room.

[0081] <Other embodiments> Although the present disclosure has been described by the above disclosed embodiments, the descriptions and drawings forming part of this disclosure should not be understood to limit the present disclosure. It should be considered that various alternative embodiments, examples, and operating techniques will become apparent to those skilled in the art from this disclosure.

[0082] (Variation) In a locking state detection device 10A according to a modified example, as shown in Fig. 19, a block 18 is provided which has a first abutment portion 18A and a second abutment portion 18B continuous with the first abutment portion 18A. As shown in Fig. 20, the block 18 is attached to a window 20B of a sliding opening / closing member 20.

[0083] The length of the frame material 20A illustrated in Figure 20 along the front-to-rear direction (i.e., the up-and-down direction in Figure 20) is short enough so that it does not come into contact with the abutment portion 17B when the sliding opening and closing member 20 is closed. In addition, the thickness of the window 20B is thin enough so that the surface of the window 20B facing the locking status detection device 10A does not come into contact with the abutment portion 17B as is. In other words, the modified block 18 can be used when the sliding opening and closing member does not have a portion that comes into contact with the abutment portion 17B of a frame material or the like as is.

[0084] 21, the block 18 abuts against the abutment portion 17B and adjusts the amount of pressing of the abutment portion 17B. When the block 18 is attached to the window 20B, the thickness of the block 18 can be added to the thickness of the window 20B. In other words, the block 18 increases the thickness of the window 20B in order to press the abutment portion 17B.

[0085] The second contact portion 18B of the block 18 is formed so that its thickness, measured in the left-right direction, gradually decreases from the upper side, which is the back side RR, to the lower side, which is the front side FR, in FIG. 20. The thickest thickness of the second contact portion 18B is approximately the same as the thickness of the first contact portion 18A. Therefore, as shown in FIG. 20, on the surface of the block 18 facing the contact portion 17B in plan view, the surface of the second contact portion 18B is inclined so as to intersect with the surface of the first contact portion 18A. In other words, the shape of the block 18 is a rectangular prism with a trapezoidal base.

[0086] 20, as window 20B slides in the front-to-rear direction to close, the thickness of block 18 at the position where abutment portion 17B of locking status detection device 10A abuts gradually increases. In other words, the amount of pressing of abutment portion 17B gradually increases. This makes it easier to smoothly press abutment portion 17B into housing 11. Other configurations of locking status detection device 10A according to the modified example are the same as those of locking status detection device 10 according to the present embodiment, and therefore redundant explanations will be omitted.

[0087] As with the present embodiment, the locking state detection device 10A according to the modified example can also prevent the transmission of a locking signal when the crescent lock 22 is in an unlocked state. Furthermore, in the modified example, even for various sliding opening / closing members 20 of different specifications, by attaching the block 18 to the sliding opening / closing member 20, the block 18 will come into contact with the contact portion 17B when the sliding opening / closing member 20 is closed. This allows the lever of the unlocking member 14 to swing to the unlocked position PF.
