Summary of the Invention

Problems to be Solved by the Invention

[0004] However, since the conventional electronic lock has a configuration that covers the surface of the door on which the thumb turn is installed, the air permeability between the back surface of the electronic lock and the surface of the door is poor, and there is a risk of condensation and corrosion on the back surface of the electronic lock and the surface of the door. In addition, in the conventional electronic lock, since almost no ultraviolet light enters between the back surface of the electronic lock and the surface of the door, there is a risk of uneven burning on the surface of the door. This uneven burning emphasizes the portion of the door surface that was covered by the electronic lock when the electronic lock was removed, which is not aesthetically pleasing. Furthermore, in the conventional electronic lock, there is a risk that the back surface of the electronic lock and the surface of the door will fuse together.

Means for Solving the Problems

[0005] An electronic lock mounting structure according to an embodiment is an electronic lock mounting structure for mounting an electronic lock on a thumb turn device installed on a door, and includes an engaging portion provided on the electronic lock and an engaged portion provided on the thumb turn device. The engaging portion is engaged with the engaged portion in a state where a gap having a predetermined interval is formed between the back surface of the electronic lock and the front surface of the door.

Advantages of the Invention

[0006] According to one embodiment, the light incident property and air permeability between the back surface of the electronic lock and the front surface of the door can be enhanced.

Modes for Carrying Out the Invention

[0008] Hereinafter, an embodiment will be described with reference to the drawings. In each of the embodiments described below, the direction corresponding to the vertical direction of the surface 20A of the door 20 is defined as the Z-axis direction. Also, the direction corresponding to the left-right direction of the surface 20A of the door 20 is defined as the X-axis direction. Further, the direction orthogonal to the surface 20A of the door 20 is defined as the Y-axis direction.

[0009] 〔First Embodiment〕 (Schematic Configuration of the Electronic Lock Unit 10) FIG. 1 is a diagram showing a schematic configuration of an electronic lock unit 10 according to the first embodiment. The electronic lock unit 10 shown in FIG. 1 is for rotating the knob portion 132 of the thumb turn device 130 provided on the door 20 by remote operation via wireless communication (e.g., Bluetooth (registered trademark), Wi-Fi (registered trademark), etc.) from various wireless devices (e.g., smartphones, remote controls, etc.), thereby enabling locking and unlocking of the door 20 by the thumb turn device 130. As shown in FIG. 1, the electronic lock unit 10 includes an electronic lock 100, an attachment 120, and a thumb turn device 130. Note that the attachment 120 and the thumb turn device 130 constitute an electronic lock attachment structure 10A.

[0010] The thumb-turn device 130 has a pedestal 131 and a knob portion 132. The pedestal 131 is screwed and fixed to the door 20 in a state of protruding from the indoor-side surface 20A of the door 20. In the example shown in FIG. 1, the thumb-turn device 130 is replaced from an existing one on the door 20 with one that can engage with the attachment 120. The pedestal 131 rotatably holds the knob portion 132. In the example shown in FIG. 1, the pedestal 131 has a rectangular parallelepiped shape. Further, the pedestal 131 has a plurality of groove portions 131A formed by linearly notching each of the left and right side surfaces in the vertical direction (Z-axis direction). The groove portion 131A is an example of an "engaged portion". In the example shown in FIG. 1, the pedestal 131 has groove portions 131A1, 131A2, and 131A3 on each of the left and right side surfaces in order from the surface 20A of the door 20. In each of the groove portions 131A1, 131A2, and 131A3, locking portions 131B1, 131B2, and 131B3 are provided so as to protrude at a predetermined height position. The knob portion 132 is provided so as to protrude from the surface of the pedestal 131. The knob portion 132 can be switched between a state in which the door 20 is locked and a state in which the door 20 is unlocked by rotating about a rotation center axis AX1 extending in a direction (Y-axis direction) orthogonal to the surface 20A of the door 20.

[0011] The electronic lock 100 is attached to the thumb-turn device 130 via the attachment 120. Specifically, the electronic lock 100 is integrated with the attachment 120 by screwing and fixing the attachment 120, and can be attached (engaged) to the thumb-turn device 130. On the lower side (Z-axis negative direction) of the housing 101 of the electronic lock 100, a substantially cylindrical thumb-turn holder 102 protruding toward the back surface 101A side is provided. The thumb-turn holder 102 is rotatable about a rotation center axis AX2 extending in a direction (Y-axis direction) orthogonal to the surface 20A of the door 20 by driving a motor (not shown) provided inside the housing 101. A groove portion 102A having a certain width and linearly notched is formed on the surface of the thumb-turn holder 102 (the surface facing the thumb-turn device 130).

[0012] The attachment 120 is a resin member for attaching the electronic lock 100 to the thumb turn device 130. For the attachment 120, one that is compatible with the thumb turn device 130 after replacement from the one originally provided on the door 20 is used. The attachment 120 is screwed and fixed to the back surface 101A of the housing 101 of the electronic lock 100 with four screws 122 from the back surface 120B side of the attachment 120. An opening 120A having substantially the same outer shape as that of the pedestal 131 is formed below the back surface 120B of the attachment 120. On each of the left and right inner wall surfaces of the opening 120A, rib portions 121 extending in the vertical direction with a certain width (a width slightly smaller than that of the groove portion 131A) are provided protruding. The rib portion 121 is an example of an "engagement portion". A locking recess 121A is formed at a predetermined height position in the rib portion 121.

[0013] (Mounting procedure of the electronic lock 100) FIG. 2 is a diagram showing the mounting procedure of the electronic lock 100 according to the first embodiment.

[0014] When attaching the electronic lock 100 to the thumb turn device 130, first, as shown in FIG. 2(a), the longitudinal direction of the knob portion 132 is set to the vertical direction (Z-axis direction) by rotating the knob portion 132 as necessary.

[0015] Next, as shown in FIG. 2(b), the electronic lock 100 integrated with the attachment 120 is slid downward (in the negative Z-axis direction) from the upper side (positive Z-axis side) of the thumb turn device 130. At this time, each of the pair of rib portions 121 of the attachment 120 is slid into each of the pair of groove portions 131A (any one of the groove portions 131A1, 131A2, 131A3) formed on the left and right side surfaces of the pedestal 131.

[0016] Then, as shown in Fig. 2(c), by sliding the electronic lock 100 downward to a predetermined height position, with each of the pair of rib portions 121 engaged with each of the pair of groove portions 131A, the thumb turn device 130 is accommodated in the opening 120A of the attachment 120, and the attachment of the electronic lock 100 to the thumb turn device 130 is completed.

[0017] At this time, when the rib portion 121 of the attachment 120 engages with the groove portion 131A of the thumb turn device 130, the movement of the electronic lock 100 in the front-rear direction (Y-axis direction) with respect to the thumb turn device 130 is restricted, so that the electronic lock 100 does not easily fall off from the thumb turn device 130.

[0018] Also, when the lock portion 131B provided to protrude into the groove portion 131A of the thumb turn device 130 engages with the locking recess 121A formed in the rib portion 121, the upward movement (positive Z-axis direction) of the electronic lock 100 with respect to the thumb turn device 130 is restricted, so that the electronic lock 100 does not easily fall off from the thumb turn device 130. However, the lock portion 131B can be switched to a state where it does not protrude from the groove portion 131A by manual operation of the operation portion 131C (see Fig. 1) exposed from the bottom surface of the pedestal 131, whereby the electronic lock 100 can be removed from the thumb turn device 130.

[0019] Also, as the electronic lock 100 slides downward, the knob portion 132 enters and engages with the groove portion 102A of the thumb turn holder 102 provided in the electronic lock 100. And the rotation center axis AX2 which is the rotation center of the thumb turn holder 102 and the rotation center axis AX1 which is the rotation center of the knob portion 132 coincide with each other. Thereby, the electronic lock 100 can switch between the state where the door 20 is locked and the state where the door 20 is unlocked by rotating the thumb turn holder 102 by remote operation from various wireless devices to rotate the knob portion 132.

[0020] As shown in Fig. 2, the electronic lock 100 has a knob 103 provided so as to be exposed from the surface 101B of the housing 101. The knob 103 is rotatable together with the thumb turn holder 102. Therefore, the user can rotate the thumb turn holder 102 by manually rotating the knob 103, and rotate the knob portion 132 engaged with the groove portion 102A of the thumb turn holder 102.

[0021] In this way, the electronic lock unit 10 according to the first embodiment can easily and firmly attach the electronic lock 100 to the thumb turn device 130.

[0022] (Gap 10B formed by the electronic lock unit 10) Fig. 3 is a view of the electronic lock unit 10 according to the first embodiment as viewed from the right side. As described with reference to Fig. 2, when the electronic lock 100 is attached to the thumb turn device 130 by engaging the rib portion 121 of the attachment 120 with the groove portion 131A of the thumb turn device 130, a gap 10B having a predetermined interval is formed between the back surface 120B of the attachment 120 and the surface 20A of the door 20. Since the attachment 120 is integrated with the electronic lock 100, the back surface 120B of the attachment 120 corresponds to the "back surface of the electronic lock".

[0023] In particular, the electronic lock unit 10 according to the first embodiment can adjust the interval of the gap 10B to any one of an interval D1, an interval D2, and an interval D3 by selectively changing the groove portion 131A that engages with the rib portion 121 formed on the attachment 120 from among the three groove portions 131A (groove portion 131A1, groove portion 131A2, and groove portion 131A3) formed on the side surface of the pedestal 131 of the thumb turn device 130.

[0024] For example, FIG. 3(a) shows an example in which the rib portion 121 of the attachment 120 is engaged with the groove portion 131A1 formed at the position farthest from the surface 20A of the door 20. In this case, a gap 10B having the largest interval D1 is formed between the back surface 120B of the attachment 120 and the surface 20A of the door 20.

[0025] Also, for example, FIG. 3(b) shows an example in which the rib portion 121 of the attachment 120 is engaged with the groove portion 131A2 formed at the second farthest position from the surface 20A of the door 20. In this case, a gap 10B having the second largest interval D2 is formed between the back surface 120B of the attachment 120 and the surface 20A of the door 20.

[0026] Also, for example, FIG. 3(c) shows an example in which the rib portion 121 of the attachment 120 is engaged with the groove portion 131A3 formed at the position closest to the surface 20A of the door 20. In this case, a gap 10B having the smallest interval D3 is formed between the back surface 120B of the attachment 120 and the surface 20A of the door 20.

[0027] At this time, no matter which groove portion 131A is engaged, since the lock portions 131B1, 131B2, and 131B3 are provided in each groove portion, the movement of the electronic lock 100 in the Z-axis direction can be restricted. Further, the operation portion 131C has a structure that can commonly operate the lock portions 131B1, 131B2, and 131B3, so that the electronic lock 100 can be removed from the thumb-turn device 130 by one operation portion 131C regardless of which groove portion 131A it is engaged with.

[0028] Also, regarding the height of the knob portion 132 of the thumb-turn device 130 in the Y-axis direction and the depth of the groove portion 102A of the thumb-turn holder 102 in the Y-axis direction, by presetting dimensions such that the knob portion 132 and the groove portion 102A can be sufficiently engaged regardless of which groove portion 131A is selected, it is not necessary to change the components of the electronic lock 100 or the thumb-turn device 130 according to the interval of the gap 10B.

[0029] Note that the intervals D1 to D3 are all set to values that can sufficiently allow ultraviolet light UV to enter between the back surface 120B of the attachment 120 and the front surface 20A of the door 20 compared to the prior art, and can sufficiently enhance the air permeability between the back surface 120B of the attachment 120 and the front surface 20A of the door 20.

[0030] The electronic lock unit 10 according to the first embodiment can sufficiently allow ultraviolet light UV to enter the gap 10B by forming a gap 10B between the back surface 120B of the attachment 120 and the front surface 20A of the door 20. Thereby, the electronic lock unit 10 according to the first embodiment can suppress, for example, uneven burning caused by ultraviolet light UV on the front surface 20A of the door 20.

[0031] Further, the electronic lock unit 10 according to the first embodiment can sufficiently enhance the air permeability inside the gap 10B by forming a gap 10B between the back surface 120B of the attachment 120 and the front surface 20A of the door 20. Thereby, the electronic lock unit 10 according to the first embodiment can suppress, for example, condensation and corrosion from occurring on the back surface 120B of the attachment 120 and the front surface 20A of the door 20.

[0032] Note that in the electronic lock unit 10 according to the first embodiment, the pedestal 131 of the thumb turn device 130 may have two or fewer groove portions 131A, or may have four or more groove portions 131A.

[0033] Also, in the electronic lock unit 10 according to the first embodiment, the groove portion 131A of the thumb turn device 130 is made into one, and a plurality of rib portions 121 of the attachment 120 of the electronic lock unit 10 are formed in a direction perpendicular to the Y axis, and the gap 10B may be adjusted by selecting the rib portion 121 at any position.

[0034] Also, in the electronic lock unit 10 according to the first embodiment, a groove portion may be provided on the attachment 120 side, and a rib portion may be provided on the pedestal 131 side of the thumb turn device 130.

[0035] Also, in the electronic lock unit 10 according to the first embodiment, the groove portion 131A and the rib portion 121 may be provided to linearly extend in the left - right direction (X - axis direction). That is, the electronic lock 100 may be attached to the thumb turn device 130 by sliding it in the left - right direction (X - axis direction).

[0036] Further, in the electronic lock unit 10 according to the first embodiment, by providing a mark corresponding to the position of the rib portion 121 on the side surface of the attachment 120 so that the position where the rib portion 121 of the attachment 120 is formed can be discriminated from the appearance of the electronic lock unit 10, it is also possible to make the work easier as a guide at the time of attachment.

[0037] Note that the case of corrosion means, for example, when the surfaces of the four screws 122 exposed on the back surface 120B side of the attachment 120 come into contact with the surface 20A of the metal door 20 and are ionized to cause corrosion (galvanic corrosion), or when the resin attachment 220 causes a chemical reaction and melts when the resin film or coating for decorating the surface 20A of the door 20 has different properties. Also, it is conceivable that due to the dew condensation on the surface 20A of the door 20, the four screws 122 are oxidized and rusted, causing the surface 20A of the door 20 to corrode. Therefore, since the electronic lock unit 10 according to the first embodiment can form a gap 10B between the back surface 120B of the attachment 120 and the surface 20A of the door 20, it is possible to surely prevent the corrosion occurring on the surface 20A of the door 20 without particularly providing a configuration for preventing corrosion.

[0038] 〔Second Embodiment〕 Next, the second embodiment will be described. Hereinafter, the electronic lock unit 10 - 2 according to the second embodiment will be mainly described with respect to the points of change from the electronic lock unit 10 according to the first embodiment.

[0039] (Schematic Configuration of Electronic Lock Unit 10 - 2) FIG. 4 is a diagram showing a schematic configuration of the electronic lock unit 10-2 according to the second embodiment. FIG. 5 is an external perspective view of the plate 233 and the spacer 234 included in the thumb turn device 230 according to the second embodiment.

[0040] As shown in FIG. 4, the electronic lock unit 10-2 is configured to include an electronic lock 100, an attachment 220, and a thumb turn device 230. Note that the attachment 220 and the thumb turn device 230 constitute an electronic lock attachment structure 10-2A. Also, since the electronic lock 100 is the same as that in the first embodiment, the description thereof is omitted.

[0041] The thumb turn device 230 has a pedestal 231, a knob portion 232, a plate 233, and a spacer 234. In the example shown in FIG. 4, the existing thumb turn device 230 on the door 20 is used. However, for the thumb turn device 230, the plate 233 and the spacer 234 are additionally provided between the pedestal 231 and the surface 20A of the door 20.

[0042] The pedestal 231 is fixed to the surface of the plate 233 fixed to the surface 20A of the door 20 in a state of protruding from the surface 20A on the indoor side of the door 20. The pedestal 231 is biased by a biasing member (not shown) toward the surface 20A of the door 20 and has a cylindrical portion (not shown) that rotatably holds the knob portion 232 therein. In the example shown in FIG. 4, the pedestal 231 has a frustum shape whose diameter gradually decreases as it moves away from the surface 20A of the door 20, and has a spring inside, and biases and fixes the plate 233 and the spacer 234 so as to abut against the surface 20A of the door 20.

[0043] The knob portion 232 is provided so as to protrude from the surface of the pedestal 231. The knob portion 232 can be switched between a state in which the door 20 is locked and a state in which the door 20 is unlocked by rotating about a rotation center axis AX1 extending in a direction (Y-axis direction) orthogonal to the surface 20A of the door 20.

[0044] The plate 233 is provided on the surface side (positive Y-axis side) of the spacer 234 between the back surface of the pedestal 231 and the surface 20A of the door 20. The plate 233 is a flat and annular member formed by using a metal material. The plate 233 is screwed and fixed to the surface 20A of the door 20 by four screws 233D passing through the plate 233.

[0045] The plate 233 has a plurality of engaging claws 233A. The engaging claw 233A is an example of an "engaged portion". The engaging claw 233A is provided to protrude outward in the radial direction from the outer peripheral edge of the plate 233. In the example shown in FIG. 5, the plate 233 has four engaging claws 233A arranged at 90-degree intervals. In particular, in the example shown in FIG. 5, the plate 233 has two engaging claws 233A protruding in the vertical direction (Z-axis direction) and two engaging claws 233A protruding in the horizontal direction (X-axis direction).

[0046] Also, a circular opening 233B centered on the rotation center axis AX1 is formed at the center of the plate 233. A cylindrical portion for accommodating the rotation shaft portion (not shown) of the knob portion 232 is inserted into the opening 233B. The opening 233B has a notch portion 233C that is notched outward in the radial direction from the inner peripheral edge portion of the opening 233B. In the example shown in FIG. 5, the opening 233B has a notch portion 233C notched upward (positive Z-axis direction) and a notch portion 233C notched downward (negative Z-axis direction).

[0047] The notch 233C is formed to allow an attachment (not shown) for attaching the thumb turn device 230 provided on the back side (negative Z-axis side) of the pedestal 231 to the door 20 to be inserted from the front side (positive Z-axis side) of the plate 233 to the back side (negative Z-axis side) of the plate 233. In the thumb turn device 230 according to the second embodiment, the convex portion of the attachment attached to the cylindrical portion housed in the pedestal 231 is inserted into the back side (negative Z-axis side) of the plate 233, so that the rotational position of the thumb turn device 230 is positioned. Thereby, the knob portion 232 can be installed in parallel with the horizontal direction (Z-axis direction) of the front surface 20A of the door 20.

[0048] The spacer 234 is provided on the back side (negative Y-axis side) of the plate 233 between the back surface of the pedestal 231 and the front surface 20A of the door 20. The spacer 234 is a flat and annular member having a constant thickness in a direction parallel to the rotation center axis AX1.

[0049] A circular opening 234A centered on the rotation center axis AX1 is formed in the center of the spacer 234. A rotation shaft portion (not shown) of the knob portion 232 is inserted into the opening 234A. Further, four through holes 234B penetrating the spacer 234 are formed at 90-degree intervals in the same circumferential shape in the spacer 234. Screws 233D for screwing and fixing the plate 233 are inserted into the through holes 234B. The spacer 234 is disposed between the plate 233 and the front surface 20A of the door 20. Then, the spacer 234 is sandwiched between the spacer 234 and the front surface 20A of the door 20 when the plate 233 is screwed and fixed to the front surface 20A of the door 20.

[0050] The spacer 234 is provided to fix the plate 233 at a position away from the surface 20A of the door 20 in the positive Y-axis direction. That is, the thickness of the spacer 234 defines the separation distance of the plate 233 from the surface 20A of the door 20. The thumb turn device 230 according to the second embodiment has a plurality of spacers 234 with different thicknesses from each other (see FIG. 7). Thereby, the thumb turn device 230 according to the second embodiment can change the separation distance of the plate 233 from the surface 20A of the door 20 by changing the spacer 234.

[0051] The attachment 220 is a resin member for enabling the electronic lock 100 to be attached to the thumb turn device 230. The attachment 220 is screwed and fixed to the back surface 101A of the housing 101 of the electronic lock 100 with four screws 222 from the back surface 220B side of the attachment 220. A circular opening 220A centered on the rotation center axis AX2 is formed below the back surface 220B of the attachment 220. The opening 220A is an example of an "engagement portion". The pedestal 231 of the thumb turn device 230 is inserted into the opening 220A. Further, the engagement claw 233A of the plate 233 engages with the inner peripheral edge of the opening 220A. The opening 220A has a notch portion 220C cut out radially outward from the inner peripheral edge of the opening 220A. In the example shown in FIG. 5, the opening 220A has four notch portions 220C arranged at 90-degree intervals and cut out in a direction 45 degrees different from the X-axis direction and the Y-axis direction. A narrow groove-like portion 220Ca is formed in the circumferential direction from the end portion in the Y-axis direction of the notch portion 220C. The groove-like portion 220Ca is formed to have a depth and width into which the engagement claw 233A of the plate 233 can be inserted.

[0052] (Mounting procedure of the electronic lock 100) FIG. 6 is a diagram showing the mounting procedure of the electronic lock 100 according to the second embodiment.

[0053] When attaching the electronic tablet 100 to the thumb turn device 230, first, as shown in Fig. 6(a), with the electronic tablet 100 in a state where the rotation center axis AX2 coincides with the rotation center axis AX1 and the electronic tablet 100 tilted by about 45 degrees so that the notch 220C aligns with the engaging claw 233A of the plate 233, it is pushed into the surface 20A of the door 20 (i.e., in the negative Y-axis direction). As a result, the pedestal 231 of the thumb turn device 230 is inserted into the opening 220A of the attachment 220. Next, as shown in Fig. 6(a), by rotating the electronic tablet 100 counterclockwise by 45 degrees around the rotation center axis AX2, alignment is achieved in a state where each of the four engaging claws 233A of the plate 233 fits into each of the groove-shaped portions 220Ca formed in each of the four notch portions 220C of the opening 220A of the attachment 220. As a result, each of the four engaging claws 233A can be positioned in the groove-shaped portion 220Ca formed inside (on the positive Y-axis side) the opening 220A of the attachment 220. Also, at this time, in accordance with the state where the thumb turn device 230 is in the unlocking position, the rotational position of the groove 102A of the thumb turn holder 102 is fixed by a fixing jig (not shown), and with the electronic tablet 100 rotated by 45 degrees, the longitudinal direction of the knob portion 232 is made to coincide with the longitudinal direction of the groove 102A of the thumb turn holder 102 of the electronic tablet 100. Thereby, as the electronic tablet 100 is pushed in the negative Y-axis direction, the knob portion 232 can be engaged in the groove 102A of the thumb turn holder 102 of the electronic tablet 100.

[0054] Next, as shown in Fig. 6(b), the electronic tablet 100 is rotated clockwise by 45 degrees around the rotation center axis AX2. As a result, each of the four engaging claws 233A of the pedestal 231 of the thumb turn device 230 engages with the inner peripheral edge portion inside (on the positive Y-axis side) the opening 220A of the attachment 220.

[0055] As a result, as shown in FIG. 6(c), with the pedestal 231 inserted through the opening 220A, the electronic lock 100 and the attachment 220 are fixed to the plate 233 of the thumb turn device 230. Thus, the attachment of the electronic lock 100 to the thumb turn device 230 is completed.

[0056] At this time, each of the four engaging claws 233A of the pedestal 231 of the thumb turn device 230 engages with the groove-shaped portion 220Ca formed on the inner peripheral edge of the opening 220A of the attachment 220, thereby restricting the movement of the electronic lock 100 in the front-rear direction (Y-axis direction) with respect to the thumb turn device 230. Thus, the electronic lock 100 is prevented from easily falling off the thumb turn device 230.

[0057] Also, the groove-shaped portion 220Ca formed on the inner peripheral edge of the opening 220A of the attachment 220 is formed as an inclined surface with a gradually decreasing width, and by the engagement frictional force between each of the four engaging claws 233A of the pedestal 231 of the thumb turn device 230 and the groove-shaped portion 220Ca formed on the inner peripheral edge of the opening 220A of the attachment 220, a configuration is adopted to suppress unnecessary rotation of the electronic lock 100 with respect to the thumb turn device 230, so that the electronic lock 100 can be fixed so as not to easily rotate to a removable rotation angle from the thumb turn device 230.

[0058] However, by rotating the electronic lock 100 counterclockwise by 45 degrees again about the rotation center axis AX2, the engagement of each of the four engaging claws 233A with the groove-shaped portion 220Ca formed on the inner peripheral edge of the opening 220A is released, and thereby the electronic lock 100 can be removed from the thumb turn device 230.

[0059] When the electronic lock 100 is attached to the thumb turn device 230, the knob portion 232 enters and engages into the groove portion 102A of the thumb turn holder 102 provided in the electronic lock 100. Also, the rotation center axis AX2 which is the rotation center of the thumb turn holder 102 and the rotation center axis AX1 which is the rotation center of the knob portion 232 coincide with each other. Thereby, the electronic lock 100 can rotate the thumb turn holder 102 by remote operation from various wireless devices, rotate the knob portion 232, and switch between the state where the door 20 is locked and the state where the door 20 is unlocked.

[0060] In addition, as shown in FIG. 6, the electronic lock 100 has a knob 103 provided so as to be exposed from the surface 101B of the housing 101. The knob 103 can rotate together with the thumb turn holder 102. For this reason, the user can rotate the thumb turn holder 102 by manually rotating the knob 103, and rotate the knob portion 232 engaged with the groove portion 102A of the thumb turn holder 102.

[0061] As described above, the electronic lock unit 10-2 according to the first embodiment can easily and firmly attach the electronic lock 100 to the thumb turn device 230.

[0062] (Gap 10-2B formed by the electronic lock unit 10-2) FIG. 7 is a view of the electronic lock unit 10-2 according to the second embodiment as viewed from the right side. As described with reference to FIG. 6, the electronic lock unit 10-2 according to the second embodiment can attach the electronic lock 100 to the thumb turn device 230 by rotating the electronic lock 100 and engaging each of the four engaging claws 233A of the thumb turn device 230 with the inner peripheral edge of the opening 220A of the attachment 220. At this time, since a spacer 234 having a certain thickness is provided between the plate 233 and the surface 20A of the door 20, a gap 10-2B having a predetermined interval is formed between the back surface 220B of the attachment 220 and the surface 20A of the door 20. Note that since the attachment 220 is integrated with the electronic lock 100, the back surface 220B of the attachment 220 corresponds to the "back surface of the electronic lock".

[0063] In particular, the electronic lock unit 10-2 according to the second embodiment can adjust the interval of the gap 10-2B to any one of an interval D4, an interval D5, and an interval D6 by selectively changing the spacer 234 disposed between the plate 233 and the surface 20A of the door 20 from among three spacers 234 having different thicknesses from each other.

[0064] For example, FIG. 7(a) shows an example in which the spacer 234-1 having the largest thickness is disposed between the plate 233 and the surface 20A of the door 20. In this case, a gap 10-2B having the largest interval D4 is formed between the back surface 220B of the attachment 220 and the surface 20A of the door 20.

[0065] Further, for example, FIG. 7(b) shows an example in which the spacer 234-2 having the second largest thickness is disposed between the plate 233 and the surface 20A of the door 20. In this case, a gap 10-2B having the second largest interval D5 is formed between the back surface 220B of the attachment 220 and the surface 20A of the door 20.

[0066] Further, for example, FIG. 7(c) shows an example in which the spacer 234-3 with the smallest thickness is disposed between the plate 233 and the surface 20A of the door 20. In this case, a gap 10-2B having the smallest interval D6 is formed between the back surface 220B of the attachment 220 and the surface 20A of the door 20.

[0067] Note that all of the intervals D4 to D6 are set to values that enable sufficient incidence of ultraviolet light UV between the back surface 220B of the attachment 220 and the surface 20A of the door 20 as compared with the prior art, and that can sufficiently enhance the air permeability between the back surface 220B of the attachment 220 and the surface 20A of the door 20.

[0068] The electronic lock unit 10-2 according to the second embodiment can sufficiently let ultraviolet light UV enter the gap 10-2B by forming the gap 10-2B between the back surface 220B of the attachment 220 and the surface 20A of the door 20. Thereby, the electronic lock unit 10-2 according to the second embodiment can suppress, for example, uneven burning caused by ultraviolet light UV on the surface 20A of the door 20.

[0069] Further, the electronic lock unit 10-2 according to the second embodiment can sufficiently enhance the air permeability within the gap 10-2B by forming the gap 10-2B between the back surface 220B of the attachment 220 and the surface 20A of the door 20. Thereby, the electronic lock unit 10-2 according to the second embodiment can suppress, for example, the occurrence of dew condensation and corrosion on the back surface 220B of the attachment 220 and the surface 20A of the door 20.

[0070] Note that in the electronic lock unit 10-2 according to the second embodiment, the thumb turn device 230 may have two spacers 234 with different thicknesses from each other, or may have four or more spacers 234 with different thicknesses from each other.

[0071] Also, in the electronic lock unit 10-2 according to the second embodiment, a plurality of spacers 234 may be stacked and installed between the plate 233 and the surface 20A of the door 20. In this case, the electronic lock unit 10-2 can adjust the interval of the gap 10-2B by changing the number or combination of the plurality of spacers 234.

[0072] Also, in the electronic lock unit 10-2 according to the second embodiment, since the positional relationship between the thumb turn device 230 and the electronic lock 100 in the positive Y-axis direction from the plate 233 does not change depending on the interval of the gap 10-2B, there is no need to change the parts of the electronic lock 100.

[0073] [Third Embodiment] Next, the third embodiment will be described. Hereinafter, for the electronic lock unit 10-3 according to the third embodiment, the points of change from the electronic lock unit 10 according to the first embodiment will be mainly described.

[0074] (Schematic Configuration of Electronic Lock Unit 10-3) FIG. 8 is a diagram showing a schematic configuration of an electronic lock unit 10-3 according to the third embodiment. As shown in FIG. 8, the electronic lock unit 10-3 includes an electronic lock 100, an attachment 120-2, and a thumb turn device 130-2. The attachment 120-2 and the thumb turn device 130-2 constitute an electronic lock mounting structure 10-3A. Also, since the electronic lock 100 is the same as that in the first embodiment, the description thereof is omitted.

[0075] The thumb turn device 130-2 is different from the thumb turn device 130 according to the first embodiment in that the pedestal 131 has one groove portion 131A on each of the left and right side surfaces. However, the groove portion 131A according to the third embodiment is larger in width in the Y-axis direction than the groove portion 131A according to the first embodiment. Accordingly, the lock portion 131B according to the third embodiment is larger in width in the Y-axis direction than the lock portion 131B according to the first embodiment.

[0076] The attachment 120-2 is different from the attachment 120 according to the first embodiment in that it further includes four spacers 123 on the back surface 120B. The spacers 123 are provided to fix the attachment 120-2 at a position away from the front surface 20A of the door 20 in the positive Y-axis direction. That is, the thickness of the spacer 123 defines the separation distance of the attachment 120-2 from the front surface 20A of the door 20. The attachment 120-2 according to the third embodiment has a plurality of types of spacers 123 with different thicknesses from each other (see FIG. 9). Thereby, the attachment 120-2 according to the second embodiment can change the separation distance from the front surface 20A of the door 20 by exchanging the spacers 123.

[0077] (Gap 10-3B formed by the electronic lock unit 10-3) FIG. 9 is a view of the electronic lock unit 10-3 according to the third embodiment viewed from the right side. Similar to the first embodiment, the electronic lock unit 10-3 according to the third embodiment can attach the electronic lock 100 to the thumb turn device 130-2 by engaging the rib portion 121 of the attachment 120-2 with the groove portion 131A of the thumb turn device 130-2.

[0078] However, in the electronic lock unit 10-3 according to the third embodiment, since the width of the groove portion 131A of the thumb turn device 130-2 is larger than the width of the rib portion 121 of the attachment 120-2, the electronic lock 100 can move in the Y-axis direction within the range of the width of the groove portion 131A of the thumb turn device 130-2.

[0079] Therefore, in the electronic lock unit 10-3 according to the third embodiment, by providing four spacers 123 on the back surface 120B of the attachment 120-2, a gap 10-3B having a predetermined interval is formed between the back surface 120B of the attachment 120-2 and the front surface 20A of the door 20. Since the attachment 120-2 is integrated with the electronic lock 100, the back surface 120B of the attachment 120-2 corresponds to the "back surface of the electronic lock".

[0080] In particular, for the electronic lock unit 10-3 according to the third embodiment, by selectively changing the spacer 123 disposed on the back surface 120B of the attachment 120-2 from among three types of spacers 123 having different thicknesses, the interval of the gap 10-3B can be adjusted to any one of an interval D7, an interval D8, and an interval D9.

[0081] For example, FIG. 9(a) shows an example in which the spacer 123-1 having the largest thickness is disposed on the back surface 120B of the attachment 120-2. In this case, a gap 10-3B having the largest interval D7 is formed between the back surface 120B of the attachment 120-2 and the surface 20A of the door 20.

[0082] Also, for example, FIG. 9(b) shows an example in which the spacer 123-2 having the second largest thickness is disposed on the back surface 120B of the attachment 120-2. In this case, a gap 10-3B having the second largest interval D8 is formed between the back surface 120B of the attachment 120-2 and the surface 20A of the door 20.

[0083] Also, for example, FIG. 9(c) shows an example in which the spacer 123-3 having the smallest thickness is disposed on the back surface 120B of the attachment 120-2. In this case, a gap 10-3B having the smallest interval D9 is formed between the back surface 120B of the attachment 120-2 and the surface 20A of the door 20.

[0084] Note that each of the intervals D7 to D9 can sufficiently allow the ultraviolet light UV to enter between the back surface 120B of the attachment 120-2 and the surface 20A of the door 20 as compared with the prior art, and the air permeability between the back surface 120B of the attachment 120-2 and the surface 20A of the door 20 is set to a value that can sufficiently enhance the air permeability.

[0085] The electronic lock unit 10-3 according to the third embodiment forms a gap 10-3B between the back surface 120B of the attachment 120-2 and the front surface 20A of the door 20, so that ultraviolet light UV can be sufficiently incident into the gap 10-3B. Thereby, the electronic lock unit 10-3 according to the third embodiment can suppress, for example, uneven burning caused by ultraviolet light UV on the front surface 20A of the door 20.

[0086] Further, the electronic lock unit 10-3 according to the third embodiment forms a gap 10-3B between the back surface 120B of the attachment 120-2 and the front surface 20A of the door 20, so that the air permeability within the gap 10-3B can be sufficiently increased. Thereby, the electronic lock unit 10-3 according to the third embodiment can suppress, for example, the occurrence of condensation and corrosion on the back surface 120B of the attachment 120-2 and the front surface 20A of the door 20.

[0087] In the electronic lock unit 10-3 according to the third embodiment, the attachment 120-2 may have two types of spacers 123 with different thicknesses from each other, or may have three or more types of spacers 123 with different thicknesses from each other.

[0088] Further, in the electronic lock unit 10-3 according to the third embodiment, a plurality of spacers 123 may be stacked and installed on the back surface 120B of the attachment 120-2. In this case, the electronic lock unit 10-3 can adjust the interval of the gap 10-3B by changing the number or combination of the plurality of spacers 123.

[0089] Further, in the electronic lock unit 10-3 according to the third embodiment, the spacer 123 may be adhered to the back surface 120B of the attachment 120-2 by an adhesive or the like, or may be fixed by a screw or the like. Further, the spacer 123 may be integrally formed with the attachment 120-2. Further, the spacer 123 may have an adjustment mechanism capable of adjusting the thickness in the Y-axis direction. Further, the spacer 123 may be attached to the front surface 20A of the door 20.

[0090] Also, in the electronic lock unit 10-3 according to the third embodiment, the width of the groove portion 131A of the thumb turn device 130-2 may be substantially the same as the width of the rib portion 121 of the attachment 120-2. Instead, the attachment 120-2 may have a configuration that can expand and contract in the front-rear direction (X-axis direction). Also in this case, the electronic lock unit 10-3 can adjust the interval of the gap 10-3B by adjusting the thickness of the spacer 123.

[0091] Also, in the electronic lock unit 10-3 according to the third embodiment, since the external force applied to the electronic lock 100 can be received by the door 20 by the spacer 123 in addition to the engagement portion between the pedestal 131 and the electronic lock 100, the reliability regarding the attachment of the electronic lock is also improved.

[0092] Furthermore, as another embodiment, it is conceivable to configure the attachment with metal. Even in that case, since the back surface of the attachment is not corroded by electrolytic corrosion due to contact with the metal door surface, it becomes possible to provide a degree of freedom in selecting the material of the attachment.

[0093] Also, by configuring the attachment with metal and performing mirror finish, it is possible to efficiently reflect the ultraviolet light UV incident in the gap formed between the back surface of the attachment and the surface of the door, so that it is possible to suppress the occurrence of uneven burning on the surface of the door due to the ultraviolet light UV.

[0094] As described above, one embodiment of the present invention has been described in detail. However, the present invention is not limited to these embodiments, and various modifications or changes are possible within the scope of the gist of the present invention described in the claims.
