[0009] Various embodiments of the present disclosure will now be described with reference to the accompanying drawings, in which common elements are designated by the same reference numerals.

[0010] The locking / unlocking control device 1 according to the present disclosure is installed so as to be connected to, for example, a thumb turn of a door, and rotates the thumb turn in a direction to lock or unlock based on reception of a wireless signal. Fig. 1 is a front perspective view of the locking / unlocking control device 1 according to the present disclosure. Specifically, Fig. 1 is a diagram showing an example of the locking / unlocking control device 1 installed so as to be connected to a thumb turn of a door as described above.

[0011] According to FIG. 1, the locking / unlocking control device 1 according to the present disclosure includes a main body 10, a support 20, and a knob 30. The main body 10 includes a holder connected to a thumb turn provided on the surface of a door inside the main body 10 and for rotating the thumb turn in at least one of the directions for locking or unlocking the thumb turn, a rotation unit for rotating the holder in response to receiving a wireless signal from the outside, and a main body case for accommodating at least a part of the holder and at least a part of the rotation unit. The support 20 is attached to the surface of the door and supports the holder so as to be movable in a direction perpendicular to the door surface so as to adjust the distance from the door surface to the holder. The knob 30 is installed on the outside of the main body 10 and is connected to the holder, thereby enabling the thumb turn to be manually rotated in the direction for locking or unlocking the door.

[0012] In this disclosure, for convenience of explanation, the expression "the support 20 moves." However, this merely means that the positional relationship between the support 20 and other components changes relatively. In other words, the expression "the support 20 moves" may also include cases where other components move relative to the support 20.

[0013] FIG. 2 is a conceptual diagram showing a state in which the locking / unlocking control device 1 of the present disclosure is installed on a door 2. Specifically, FIG. 2 is a diagram showing an example of the case where the device is installed on the indoor space side of the door 2. According to FIG. 2, the door 2 has a knob 4 for opening and closing the door installed on the surface facing the indoor space. A thumb turn 3 for locking and unlocking the door 2 is installed on the surface facing the indoor space of the door 2 near the knob 4. The locking / unlocking control device 1 of the present disclosure is typically installed on the indoor space side of the door 2 so as to cover the thumb turn 3. At this time, a holder included in the main body 10 of the locking / unlocking control device 1 is connected to the thumb turn 3, and a support 20 is attached to the surface of the door 2 directly or via a base 5.

[0014] Here, as shown in FIG. 2 as an example, the thumb turn 3 and the knob 4 may be configured on a base 5 that is installed so as to protrude from the surface of the door 2. With regard to such a base 5, depending on the type and structure of the door 2, there are some in which the base 5 is not installed at all and the thumb turn 3 is attached directly to the surface of the door 2, and the height at which it protrudes from the surface of the door 2 varies. In other words, depending on the type and structure of the door 2, the distance from the surface of the door 2 to the thumb turn 3 varies. Therefore, the locking / unlocking control device 1 of the present disclosure is configured so that the support 20 attached to the surface of the door 2 can be moved in a direction perpendicular to the surface of the door 2, thereby making it possible to adjust the position of the holder according to the distance from the surface of the door 2 to the thumb turn 3.

[0015] In the example of Fig. 2, the support 20 is directly attached to the surface of the door 2, but the same applies to the case where it is indirectly attached via the base 5. In that case, the position of the holder can be adjusted by making the support 20 movable in the vertical direction according to the distance from the base 5 to the thumb turn 3.

[0016] Fig. 3 is an exploded perspective view of the locking / unlocking control device 1 of the present disclosure. Specifically, Fig. 3 is a diagram for explaining the specific configuration of the main body 10 and the support 20 included in the locking / unlocking control device 1. According to Fig. 3, the main body 10 includes at least a holder 17 connected to the thumb turn 3, a rotation unit 15 for applying a driving force to the holder 17 for rotating the holder 17 in at least one of the directions in which the thumb turn 3 is locked or unlocked (direction D2 or D3), a main body case 12 for respectively accommodating the upper side of the rotation unit 15 (the direction opposite to the door surface) and the upper side of the holder 17 (the direction opposite to the thumb turn 3), and a main body cover 11 detachably connected to the main body case 12 so as to cover the outer surface of the main body case. In addition to the above components, the main body 10 may also include a holder cover 14 that is detachably connected to the main body case 12 so as to cover the lower side of the holder 17 (the position opposite to the part that clamps the thumb turn 3), and a support outer cover 18 that is detachably connected to the main body case 12 so as to cover the outer surface of the support 20.

[0017] When viewed from a viewpoint along a direction perpendicular to the surface of the door 2 (direction D1), the main case 12 has a vertically elongated elliptical shape having a predetermined thickness in the same direction, and is configured to accommodate the holder 17 in approximately half of its area, and the rotating unit 15 and the support 20 in the remaining half of its area. The holder 17 is accommodated in the main case 12 by fitting the tip side of the rotating shaft of the knob 30 rotatably connected to the main cover 11 into the holder 17. The rotating unit 15 is fixed to the main case immovably using a fixing device such as a screw (not shown). Furthermore, the main case 12 includes a rail for connecting the support 20 slidably in the direction D1 perpendicular to the surface of the door 2. The rail is configured to extend from an end of the main case 12 in the direction D1 perpendicular to the main case 12 (a surface of the main case 12 that is installed parallel to the surface of the door 2).

[0018] When viewed from the perspective along the direction D1, the body cover 11 has a vertically elongated elliptical shape similar to the body case 12, and its outer shape is formed to be a predetermined amount larger than the body case 12. This allows the body cover 11 to cover the body case 12 and a battery storage section (described later) of the support 20 when connected to the body case 12. In addition, a knob 30 is provided on the body cover 11 so as to be rotatable relative to the body cover 11 at a position corresponding to the area where the holder 17 is stored.

[0019] Holder cover 14 is formed in a shape that follows the outline of the area in main case 12 where holder 17 is terminated, and is attached to fit into that area of ​​main case 12 to cover holder 17. Such holder cover 14 covers the portion of holder 17 that is not housed in main case 12, improving the design when viewed from the outside and preventing tampering with that portion.

[0020] The support outer cover 18 is formed in a shape that follows the outer shape of the roughly cylindrical support 20, and is attached so as to fit in the vicinity of the rail of the main body case 12, covering the support 20. Such a support outer cover 18 covers at least a portion of the support 20, improving the design when viewed from the outside, and can prevent tampering with that portion.

[0021] Also, according to FIG. 3, the support 20 is connected to the main body case 12 so as to be slidable in a direction D1 perpendicular to the surface of the door 2 along the rail of the main body case 12. The support 20 supports the main body 10 connected thereto by placing its bottom side on the surface of the door 2. The support 20 is formed in a substantially cylindrical shape extending along the direction D1 perpendicular to the surface of the door 2, and includes a storage structure (for example, a battery storage section) capable of storing other components therein. The storage structure includes a battery 22 that moves with the movement of the support 20 by being stored therein. As such a battery 22, a secondary battery that can be repeatedly charged by receiving power supply from an external source is preferable, but the present invention is not limited thereto, and a primary battery can also be suitably used. The battery 22 is used to share power with motors, electronic components, etc., but such power can also be directly supplied from an external power source via a power connector instead of the battery 22.

[0022] FIG. 4 is a perspective view showing a state in which the main body cover 11 of the locking / unlocking control device 1 of the present disclosure is removed from the main body case 12. Specifically, FIG. 4 is a view for showing the storage structure of the battery 22 and the connection structure of the knob 30. According to FIG. 4, the main body case 12 has an opening 121 formed along the outer shape of the support 20 in the area in which the support 20 is stored, and the opening 121 and the rail 124 form a support storage section 122. The support 20 is stored inside the support storage section 122 so that it can slide in a direction D1 perpendicular to the surface of the door 2. Here, the support 20 includes a support case 21 formed in a hollow, approximately cylindrical shape that is stored inside the support storage section 122, and a support inner cover (not shown in FIG. 4) installed on the door 2 side of the support case 21. Of these, an opening 211 is formed in the support case 21 at the end opposite to the cylindrically formed door 2. Then, inside the hollow support case 21, an accommodation structure capable of accommodating other components through the opening 211 is formed. In the present disclosure, the accommodation structure is utilized as a battery accommodation section 212 for accommodating the battery 22 in a removable manner.

[0023] The main body cover 11 includes a locking piece 111 near the center in the longitudinal direction thereof, which is inserted into a locking hole 129 of the main body case 12. The locking piece 111 is elastically formed on the main body cover 11, and has a locking claw at its tip. Therefore, when the main body cover 11 covers the main body case 12, the locking piece 111 is elastically deformed and inserted into the locking hole 129 of the main body case 12, and the locking claw at the tip is caught on the periphery of the locking hole 129, thereby connecting the main body cover 11 to the main body case 12. On the other hand, when the main body cover 11 is to be removed from the main body case 12, a load is applied to the periphery of the locking piece 111 to elastically deform the locking piece 111, and the locking piece 111 is pulled out from the locking hole 129, whereby the main body cover 11 is removed from the main body case. Note that such locking pieces 111 and locking holes 129 may be provided in a plurality of positions corresponding to each other. Further, the method of using the locking pieces 111 and the locking holes 129 has been described as a method of detachably connecting the main body cover 11 to the main body case 12, but of course other methods may be used.

[0024] As described above, the body cover 11 is detachably attached to the body case 12 by the locking pieces 111 and the locking holes 129. Furthermore, the body cover 11 is formed so as to fit the outer shape of the support housing portion 122 of the body case 12, and is therefore capable of covering the battery 22 and the opening 211 of the support case 21. Therefore, the battery 22 can be taken out from the battery housing portion 212 of the support case 21 by removing the body cover 11 from the body case 12.

[0025] Here, as shown in Fig. 4, the knob 30 is attached to the body cover 11 at a position corresponding to the area where the holder 17 of the body case 12 ends. Fig. 5 is a perspective view showing a state in which the body cover 11 of the locking / unlocking control device 1 of the present disclosure has been removed from the body case 12. Specifically, Fig. 5 is a view showing the attachment structure of the knob 30 to the body cover 11 and the connection structure of the knob 30 to the holder 17.

[0026] 5, knob tip member 311 is fixed to the end of the rotating shaft formed in the approximate center of knob 30 toward holder 17 from the rear surface of body cover 11 by screw 312 via washer 313. At this time, the rotating shaft of knob 30 is inserted into a rotating shaft insertion hole (not shown in FIG. 5) of body cover 11, and knob 30 is fixed so as to sandwich body cover 11 by knob tip member 311 formed to be larger than the width of the rotating shaft insertion hole. In this way, knob 30 is attached rotatably with respect to body cover 11.

[0027] On the other hand, the knob tip member 311 is fixed to the rotation shaft so as to protrude from the back surface of the body cover 11. When the body cover 11 is attached to the body case 12, the knob tip member 311 is inserted into the opening 123 formed in the body case 12 and fits into the knob accommodating hole 172 formed in the knob accommodating section 171 on the extension line of the rotation shaft of the holder. Here, the outer shape of the protruding part of the knob tip member 311 is formed into a substantially polygonal shape with a longitudinal distance of S1 and a lateral distance of S2. The outer shape of the knob accommodating hole 172 into which the knob tip member 311 fits is also formed into a substantially polygonal shape with a longitudinal distance of S1' and a lateral distance of S2' so as to correspond to the outer shape of the knob tip member 311. Therefore, when the knob tip member 311 is fitted into the knob accommodating hole 172, the knob 30 can be rotated to rotate the holder 17 as well. In this way, the knob 30 can be manually rotated in the direction of locking or unlocking the thumb turn 3 to rotate the holder 17 and the thumb turn 3 connected to the holder 17 as well. In addition, the length (distance) S1 of the longitudinal side of the knob tip member 31 and the length (distance) S2 of the lateral side are different from each other. Similarly, the length (distance) S1' of the longitudinal side of the knob accommodating hole 172 and the length (distance) S2' of the lateral side of the knob accommodating hole 172 are different from each other. In addition, it is not limited to this, and it is also possible to form the outer shape of the knob tip member 31 and the knob accommodating hole 172 into a square shape with each side of the same length. However, even though the knob 30 was originally installed vertically and connected to the knob receiving hole 172, the user may inadvertently rotate the knob 30 (for example, 90 degrees) when removing the main body cover 11 from the main body case 12. If the main body cover 11 is then reattached to the main body case 12 as is, if the outer shape of the knob tip member 31 and the knob receiving hole 172 is square, the knob 30 can be attached even though it is rotated 90 degrees instead of the original angle. In order to avoid such inconvenience, as described above, it is preferable that the length (distance) S1 of the longitudinal side and the length (distance) S2 of the lateral side, and the length (distance) S1' of the longitudinal side and the length (distance) S2' of the lateral side are different from each other.Furthermore, the external shapes of knob tip member 31 and knob accommodating hole 172 are merely examples, and other methods may be used, such as forming them in a circular shape or combining a protrusion and a hole.

[0028] In the example of Fig. 5, the main body cover 11 is configured to be detachable from the main body case 12 when the locking / unlocking control device 1 is in use, that is, when the holder 17 is connected to the thumb turn 3 and the battery is housed in the battery housing. Since the knob 30 is attached to the main body cover 11, it can be removed from the holder 17 together with the attachment and detachment of the main body cover 11. For example, a case may be considered in which a through hole is opened in the door 2 for fraudulent purposes, and the knob 30 is manually rotated by inserting a hand through the hole. However, even in such a case, for example, when going out, such fraud can be effectively prevented by removing the main body cover 11 together with the knob 30 from the main body case 12.

[0029] FIG. 6 is a conceptual diagram showing the state in which the support 20 of the locking / unlocking control device 1 of the present disclosure is moved. Specifically, FIG. 6 is a diagram showing the movement of the support 20 from a state in which it is completely housed in the main body 10 to a state in which it is exposed to the outside of the main body 10. Here, the thumb turn 3 to which the holder 17 of the locking / unlocking control device 1 is connected has various heights from the surface of the door 2 depending on the presence or absence of the base 5 and the height of the base 5. Therefore, it is necessary to adjust the position of the holder 17 according to the height of the thumb turn 3. Therefore, according to FIG. 6, the support 20 can change its form from a state in which it is entirely housed inside the main body case 12 and the support outer cover 18 of the main body 10 (FIG. 6(A)), to a state in which at least a part of it is exposed from the main body case 12 and the support outer cover 18 (FIG. 6(B)), and to a state in which most of it is exposed from the main body case 12 and the support outer cover 18 (FIG. 6(C)).

[0030] 6A to 6C, the movement of the support 20 has been described in three stages. However, the number of stages is not limited to three, and the number of stages may be two or more.

[0031] 7 and 8 are front perspective views of the locking / unlocking control device 1 of the present disclosure with the main body cover 11 and the support outer cover 18 removed. Specifically, FIGS. 7 and 8 are views for explaining the structure for moving the support 20 shown in FIGS. 6(A) to 6(C). According to FIG. 7, the main body case 12 has an opening 121 into which the support case 21 formed in a substantially cylindrical shape is inserted in a direction D1 perpendicular to the surface of the door 2. The main body case 12 also has a rail 124 formed at the base end portion of the opening 121 so as to extend in the direction D1 perpendicular to the surface of the door 2. The rail 124 is formed by extending a pair of grooves 124-1 and 124-2 formed toward the inside of the main body case 12 at both ends of the short side direction D4 of the main body case 12, respectively, toward the direction D1.

[0032] On the other hand, the support case 21 of the support 20 has a pair of engagement protrusions 213-1 and 213-2 at a position where it contacts the rail 124 of the main body case 12. The pair of engagement protrusions 213-1 and 213-2 are formed to extend in the direction D1 along a pair of grooves 124-1 and 124-2 formed in the rail 124. Therefore, the support case 21 is connected to the main body case 12 so as to be movable on the rail 124 of the main body case 12 by the engagement of the engagement protrusions 213-1 and 213-2 with the pair of grooves 124-1 and 124-2. In addition, the support inner cover 23 formed on the front side of the door 2 with respect to the support case 21 also moves together with the movement of the support case 21.

[0033] The support case 21 has a plurality of fitting holes 214 (fitting holes 214-1 to 214-n) formed in the surface thereof in succession along a direction D1 perpendicular to the surface of the door 2. Meanwhile, the main body case 12 has a stopper 125 formed in the vicinity of the fitting holes 214. The stopper 125 is connected to the main body case 12 so as to be slidable in the longitudinal direction of the main body case 12 by inserting one end 125a into a stopper insertion hole 126 formed in the main body case 12. In addition, a fitting protrusion for fitting into any of the plurality of fitting holes 214-1 to 214-n formed in the support case 21 is formed on the other end 125b of the stopper 125. Therefore, as described above, the support case 21 is connected to the main body case 12 so as to be able to move along the rail 124, but the movement of the support case 21 relative to the main body case 12 is restricted by the engagement of the engagement protrusion formed on the other end 125b of the stopper 125 connected to the main body case 12 with one of the engagement holes 214-1 to 214-n of the support case 21.

[0034] 7 shows a state in which the support 20 has moved to the upper end of the main body case 12 and is entirely housed inside the main body case 12 and the support outer cover 18 (not shown). At this time, the fitting protrusion formed on the other end 125b of the stopper 125 fits into the fitting hole 214-1 of the support case 21, thereby restricting the movement of the support case 21 at the position shown in FIG. R 8 shows a state in which the support 20 has moved from the upper end of the main body case 12 in a direction D1 perpendicular to the surface of the door 2, and at least a part of the support 20 is exposed from the main body case 12 and the support outer cover 18. Such movement is made possible by sliding the stopper 125 inserted into the stopper insertion hole 126 once in the longitudinal direction D5 of the main body case 12 to temporarily release the restriction on the movement of the support case 21. After the restriction is released and the support case 21 is moved to a desired position, the stopper 125 is returned to the position before sliding, so that the fitting protrusion formed on the other end 125b of the stopper 125 is fitted into the fitting hole 214-3. This makes it possible to restrict the movement of the support 20 again at the position after the movement.

[0035] Fig. 9 is a front perspective view of the rotating unit 15 and the holder 17 of the locking / unlocking control device 1 of the present disclosure. Specifically, Fig. 9 is a diagram for explaining each configuration of the rotating unit 15 and the holder 17. According to Fig. 9, the rotating unit 15 includes a motor 151 electrically connected to the battery 22 and driven by shared power, a rotating unit gear 152 that fits into a motor gear connected to the motor 151 and transmits the drive of the motor 151 to the holder 17, an antenna (not shown) for transmitting and receiving a wireless signal to the outside, and a processor (not shown) that controls the drive of the motor 151 based on the wireless signal received by the antenna.

[0036] Holder 17 includes a holder gear 173 that is engaged with rotating unit gear 152 and rotates in response to the rotation of rotating unit gear 152, a holder shaft 175 to which holder gear 173 is connected and which serves as the center of rotation of holder gear 173, a thumb turn holder 174 that is connected to the tip of holder shaft 175 and rotates together with the rotation of holder shaft 175, a dial 176 for changing the width of thumb turn holder 174, a knob accommodating portion 171 formed at the other end of holder shaft 175, and a knob accommodating hole 172 formed so as to recess knob accommodating portion 171.

[0037] As described above, the knob tip member 311 of the knob 30 is inserted into the knob accommodating hole 172, and by rotating the knob 30, the holder shaft 175 to which the knob accommodating hole 172 is connected and the thumb turn holder 174 connected to the tip of the holder shaft 175 also rotate together.

[0038] Here, the control and operation of the rotating unit 15 and the holder 17 when a wireless signal for locking the thumb turn 3 is received will be described. When the antenna receives a wireless signal from the outside by receiving power from the battery 22, the processor performs authentication based on the received wireless signal. As a result, if it is determined that the signal contains valid information, the processor transmits a drive signal to the motor 151 to supply power from the battery 22, and drives the motor 151 to rotate the motor gear in the locking direction. The rotation of the motor gear is then transmitted to the rotating unit gear 152 engaged with the motor gear, causing the rotating unit gear 152 to rotate.

[0039] When the rotating unit gear 152 is rotated, the holder gear 173 engaged with the rotating unit gear 152 is also rotated in the direction in which the thumb turn 3 is locked. Then, the holder shaft 175 connected to the holder gear 173 as a central shaft also rotates together with the rotation of the holder gear 173. As a result, the thumb turn holder 174 formed at the tip of the holder shaft 175 also rotates together with the rotation of the holder shaft 175 in the direction in which the thumb turn 3 is locked. In this way, by receiving a wireless signal for locking the thumb turn 3, the thumb turn holder 174 of the holder 17 rotates, and it is possible to rotate the thumb turn 3 sandwiched by the thumb turn holder 174 in the direction in which it is locked.

[0040] In the above, a case where a wireless signal for locking the thumb turn 3 is received has been described, but when a wireless signal for unlocking is received, the same operation and control are performed, except that the rotation directions of each gear, holder shaft, and thumb turn holder 174 are reversed. Also, while Bluetooth (registered trademark) is typically used as the wireless signal, other wireless signals such as WiFi, NFC, and cellular communications such as LTE and 5G can also be used.

[0041] 9, the thumb turn holder 174 includes a pair of first and second thumb turn holders 174-1 and 174-2. The thumb turn 3 is sandwiched between the first and second thumb turn holders 174-1 and 174-2, allowing the thumb turn 3 to rotate in accordance with the rotation of the thumb turn holder 174. Here, the shape (particularly the thickness) of the thumb turn 3 varies depending on the type, while in order for the thumb turn 3 to rotate smoothly, the width between the pair of first and second thumb turn holders 174-1 and 174-2 must be appropriately adjusted depending on the thickness of the thumb turn 3.

[0042] FIG. 10 is an A-A' cross-sectional view of the holder 17 of the locking / unlocking control device 1 of the present disclosure. Specifically, FIG. 10 is a diagram showing a structure for adjusting the width between the first thumb turn holder 174-1 and the second thumb turn holder 174-2 according to the thickness of the thumb turn 3. According to FIG. 10, the holder 17 includes a dial 176 that can be manually rotated around a dial shaft 177. A first winding portion 179-1 is formed around the dial shaft 177, which is wound in a spiral shape from the center to one end and formed in a thread shape. A second winding portion 179-2 is formed around the dial shaft 177, which is wound in a spiral shape from the center to a direction opposite to the first winding portion 179-1, and formed in a thread shape.

[0043] The holder 17 also includes a first movable piece 178-1 coupled to the first thumb turn holder 174-1 and a second movable piece 178-2 coupled to the second thumb turn holder 174-2. The first movable piece 178-1 includes a first movable gear 178-1a formed to engage with the threads of a first winding portion 179-1 formed on the dial shaft 177. Similarly, the second movable piece 178-2 includes a second movable gear 178-2a formed to engage with the threads of a second winding portion 179-2 formed on the dial shaft 177.

[0044] With this configuration, by rotating the dial 176, the dial shaft 177 coupled to the dial 176 rotates. Then, as the first winding portion 179-1 formed around the dial shaft 177 rotates, the first movable piece 178-1 engaged with the first winding portion 179-1 moves in a predetermined direction. At the same time, as the second winding portion 179-2 formed around the dial shaft 177 rotates, the second movable piece 178-2 engaged with the second winding portion 179-2 moves in the opposite direction to the first movable piece 178-1. This makes it possible to adjust the width of the first thumb turn holder 174-1 coupled to the first movable piece 178-1 and the second thumb turn holder 174-2 coupled to the second movable piece 178-2.

[0045] Fig. 10(A) shows a case where the positions of the first thumb turn holder 174-1 and the second thumb turn holder 174-2 are adjusted by rotating the dial 176 in correspondence with the thumb turn 3a having a width W1. Fig. 10(B) shows a case where the positions of the first thumb turn holder 174-1 and the second thumb turn holder 174-2 are adjusted by rotating the dial 176 in correspondence with the thumb turn 3b having a width W2 wider than the width W1. In this way, when installing the locking / unlocking control device 1, it is possible to flexibly adjust the width of the thumb turn holder 174 to match the shape of the thumb turn 3.

[0046] FIG. 11 is a bottom view of the locking / unlocking control device 1 of the present disclosure. Specifically, FIG. 11 is a diagram showing the structure of the holder 17 for clamping the thumb turn 3 and the holder accommodating section 128 formed in the main body case 12 for accommodating the holder 17. According to FIG. 11, the holder 17 is formed in a substantially circular shape as a whole because of the circular holder gear 173 when viewed from a direction perpendicular to the surface of the door 2. On the other hand, the bottom side of the main body case 12 is formed with a holder accommodating section 128 for inserting the holder 17 through the opening 127 and accommodating it therein. The holder accommodating section 128 is formed in a substantially circular shape so as to correspond to the shape of the holder 17. Therefore, when the holder 17 is fixed to the thumb turn 3, the main body 10 including the main body case 12 and the like and the support 20 can be rotated and installed in a desired direction around the holder 17.

[0047] Also, at this time, the holder 17 has a width W3 when viewed from a direction perpendicular to the surface of the door 2. On the other hand, the holder accommodating section 128 of the main body case 12 is formed so that both the vertical width W4 and the horizontal width W5 are larger than the width W3 of the holder 17 by at least a predetermined width when viewed from the same direction. By forming the holder 17 and the holder accommodating section 128 in this manner, it is possible to flexibly determine the relative positional relationship between them by the difference in width, as shown in Figures 11(A) and 11(B), for example. That is, the locking / unlocking control device 1 of During installation, the support body 20 is positioned relative to the door 2 and then the thumb turn 3 is connected to the holder 17 so as to sandwich it therebetween, making it easy to align the rotation axis of the thumb turn holder 174 of the holder 17 with the rotation axis of the thumb turn 3.

[0048] Fig. 12 is a rear perspective view of the locking / unlocking control device 1 of the present disclosure. Specifically, Fig. 12 is a diagram showing a structure for fixing the support 20 of the locking / unlocking control device 1 to the surface of the door 2. According to Fig. 12, the main body case 12 is detachably connected to the support outer cover 18 formed so as to cover the support 20 on the surface side of the door 2. Then, the support case 21 and the support inner cover 23 of the support 20 are movably arranged inside the support outer cover 18. A fixing tool for fixing the support 20 to the door 2 is installed on the cover bottom surface 231 located on the surface side of the door 2 of the support inner cover 23. That is, the support 20 is attached to the surface of the door 2 via the fixing tool.

[0049] As an example of the fastener, as shown in FIG. 12, a double-sided tape 232 that is attached to the cover bottom surface 231 and the surface of the door 2, and one or more screw holes formed in the cover bottom surface 231 are used. 234 The fixing screws 233 or screws inserted into the holes 231 may be used alone or in combination. Note that these are merely examples, and it is of course possible to use other fixing devices.

[0050] As described above, the present disclosure can provide a locking / unlocking control device that can be more easily installed on a door.

[0051] In the present disclosure, the support 20 is formed to be movable relative to the main body case 12 by aligning the engaging protrusions 213-1 and 213-2 with the rail 124 formed in a groove shape in the main body case 12. However, the movement of the support 20 does not have to be realized by a combination of the rail 124 formed in a groove shape and the engaging protrusions 213-1 and 213-2. For example, a groove may be formed in the support 20 and a protrusion may be formed in the main body case 12, or the support 20 may be formed to be movable by another method.

[0052] In the present disclosure, the movement of the support 20 is restricted by a combination of a fitting protrusion formed on the stopper 125 and a fitting hole formed on the support 20. However, the present disclosure is not limited to this, and the movement may be restricted by other known restricting means.

[0053] Also, in the present disclosure, a case has been described in which the holder 17 and the rotating unit 15 are installed in the main body 10, and the support 20 housing the battery 22 is movably connected to the main body 10. However, as long as the support 20 is movable relative to the holder 17, it is possible to change the housing positions of the components as appropriate, for example, by housing the battery 22 in the main body 10.
