Modes for Carrying Out the Invention

[0009] The following is an explanation of the electronic lock unit 10 including the electronic lock mounting structure FS according to an embodiment of the present invention. In the following, for ease of understanding of the explanation, the same reference numerals are given to the same components in each drawing as much as possible, and duplicate explanations are omitted.

[0010] FIG. 1 is a perspective view of the electronic lock unit 10 when viewed from the front side. FIG. 2 is a perspective view of the electronic lock unit 10 when viewed from the rear side. The electronic lock unit 10 is composed of an electronic lock 100, an attachment 110, and a pedestal 120. In the present embodiment, the attachment 110 and the pedestal 120 constitute an electronic lock mounting structure FS for attaching the electronic lock 100 to the door 20. However, the attachment 110 may be omitted. In this case, the electronic lock 100 may be directly fixed to the pedestal 120 by a double-sided tape or the like. Also, the attachment 110 may be integrated with the electronic lock 100, or may be integrated with the pedestal 120.

[0011] Specifically, FIG. 1(A) shows the electronic lock unit 10 in a state of being attached to the indoor surface 20A of the door 20. FIG. 1(B) shows the state of the electronic lock unit 10 when the electronic lock 100 and the attachment 110 are removed together from the pedestal 120 attached to the surface 20A of the door 20. FIG. 1(C) shows the state of the electronic lock unit 10 when the pedestal 120 and the thumb turn device 130 are separately removed from the surface 20A of the door 20. FIG. 2 shows the state of the electronic lock unit 10 removed from the door 20. Also, FIG. 2 shows the state of the electronic lock unit 10 when the pedestal 120 is removed from the attachment 110 attached to the electronic lock 100. Note that FIG. 2 also shows the cylinder mounting hole CH provided on the outdoor surface 20C of the door 20.

[0012] In each of FIGS. 1 and 2, X1 represents one direction of the X-axis that constitutes a three-dimensional orthogonal coordinate system, and X2 represents the other direction of the X-axis. Also, Y1 represents one direction of the Y-axis that constitutes a three-dimensional orthogonal coordinate system, and Y2 represents the other direction. Similarly, Z1 represents one direction of the Z-axis that constitutes a three-dimensional orthogonal coordinate system, and Z2 represents the other direction of the Z-axis. In FIGS. 1 and 2, the X1 side of the electronic lock unit 10 corresponds to the front side (front face side) of the electronic lock unit 10, and the X2 side of the electronic lock unit 10 corresponds to the rear side (rear face side) of the electronic lock unit 10. Also, the Y1 side of the electronic lock unit 10 corresponds to the left side of the electronic lock unit 10, and the Y2 side of the electronic lock unit 10 corresponds to the right side of the electronic lock unit 10. And, the Z1 side of the electronic lock unit 10 corresponds to the upper side of the electronic lock unit 10, and the Z2 side of the electronic lock unit 10 corresponds to the lower side of the electronic lock unit 10. The same applies to other members in other figures.

[0013] The electronic lock unit 10 is for enabling locking and unlocking of the door 20 by the thumb turn device 130 by rotating the thumb turn device 130 provided on the door 20 through remote operation via wireless communication (such as wireless communication by Bluetooth (registered trademark) or Wi-Fi (registered trademark), etc.) between various wireless devices (such as a smartphone or a remote control, etc.) and the electronic lock unit 10.

[0014] As shown in FIGS. 1(B) and 1(C), the thumb turn device 130 has a pedestal 131 and a knob 132. The pedestal 131 is fixed to the door 20 in a state of protruding from the surface 20A to the indoor side through a thumb turn mounting hole TH provided on the indoor side surface 20A of the door 20. FIG. 1(C) shows a state in which the thumb turn mounting hole TH provided on the surface 20A of the door 20 is exposed. The knob 132 is configured to be rotatable with respect to the pedestal 131 about an axis AX1 extending in a direction orthogonal to the surface 20A of the door 20.

[0015] The deadbolt DB disposed on the side end surface 20B of the door leaf 20 is configured to project from or retract into the side end surface 20B in response to the rotation of the knob 132. The locked state of the door leaf 20 is realized by the deadbolt DB projecting from the side end surface 20B, and the unlocked state of the door leaf 20 is realized by the deadbolt DB retracting into the side end surface 20B. FIG. 1(A) shows the state when the deadbolt DB projects from the side end surface 20B, that is, the state when the door leaf 20 is locked. Thus, the door leaf 20 is configured such that the locked state and the unlocked state are switched in response to the rotation of the knob 132.

[0016] The electronic lock 100 is configured to operate in response to remote operation by various wireless devices. Specifically, the electronic lock 100 includes a clamping mechanism SM (see FIG. 2) that clamps the knob 132 of the thumb turn device 130, and an electric motor (not shown) for rotating the clamping mechanism SM (the knob 132) around the axis AX1. Further, the electronic lock 100 is attached to the door leaf 20 via the attachment 110 and the pedestal 120. Specifically, the electronic lock 100 is attached to the attachment 110 by any means such as double-sided tape, screwing, snap fitting, or slide fitting. In the example shown in FIG. 1, the electronic lock 100 is detachably attached to the attachment 110 by slide fitting.

[0017] The attachment 110 is a member for attaching the electronic lock 100 to the pedestal 120. In the present embodiment, the attachment 110 is formed of resin. Then, the attachment 110 is attached to the pedestal 120 by any means such as double-sided tape, screwing, snap fitting, or slide fitting. In the example shown in FIG. 1, the attachment 110 is detachably attached to the pedestal 120 by slide fitting. Specifically, as shown in FIGS. 1(B) and 1(C), the pedestal 120 has a convex portion 120V formed so as to protrude forward (in the X1 direction) from the front surface (the surface on the X1 side). As shown in FIG. 2, the attachment 110 has a concave portion 110C formed so as to be recessed forward (in the X1 direction) on the rear surface (the surface on the X2 side). The convex portion 120V of the pedestal 120 and the concave portion 110C of the attachment 110 are configured to engage with each other by slide fitting.

[0018] FIG. 3 is a cross-sectional view of the convex portion 120V of the pedestal 120 and the concave portion 110C of the attachment 110. Specifically, FIG. 3(A) shows a cross-section of the attachment 110 in a plane parallel to the XY plane including the dashed line L1 in FIG. 2. FIG. 3(B) shows a cross-section of the pedestal 120 in a plane parallel to the XY plane including the dashed line L2 in FIG. 1(C). FIG. 3(C) shows a cross-section of the attachment 110 and the pedestal 120 when the concave portion 110C of the attachment 110 and the convex portion 120V of the pedestal 120 are engaged with each other.

[0019] In the example shown in FIG. 3, the convex portion 120V of the pedestal 120 has a dovetail-shaped cross section. And the concave portion 110C of the attachment 110 is configured to have a shape that matches the shape of the convex portion 120V having the dovetail-shaped cross section. Also, the lower end (the end on the Z2 side) of the concave portion 110C of the attachment 110 is open so as to be able to receive the convex portion 120V of the pedestal 120 as shown in FIG. 2. On the other hand, the upper end (the end on the Z1 side) of the concave portion 110C of the attachment 110 is configured to have an upper wall portion that contacts the upper end of the convex portion 120V of the pedestal 120. With this configuration, after the operator positions the attachment 110 above the pedestal 120 as shown in FIG. 1(B), the attachment 110 can be attached to the pedestal 120 by sliding the attachment 110 downward with the rear surface of the attachment 110 in contact with the front surface of the pedestal 120.

[0020] Next, referring to FIG. 4, a configuration example of the pedestal 120 will be described. FIG. 4 is a diagram showing a configuration example of the pedestal 120. Specifically, FIG. 4(A) is an exploded perspective view of the pedestal 120, and FIG. 4(B) is a rear view of the pedestal 120.

[0021] The pedestal 120 is composed of an engagement mechanism 121, a body member 122, a base plate 123, a ratchet gear 124, a ratchet pawl 125, a ratchet spring 126, a screw 127, and a caulking pin 128.

[0022] The engaging mechanism 121 is configured to be able to attach the pedestal 120 to the door 20 and remove the pedestal 120 from the door 20 without damaging either the indoor surface 20A or the outdoor surface 20C of the door 20. Therefore, in the present embodiment, the engaging mechanism 121 is configured to be able to attach the pedestal 120 to the thumb-turn mounting hole TH of the door 20. Specifically, the engaging mechanism 121 is configured to contact at least a part of the inner peripheral surface of the thumb-turn mounting hole TH and to be able to apply a force in a direction to expand the thumb-turn mounting hole TH at at least two locations on the inner peripheral surface of the thumb-turn mounting hole TH. The pedestal 120 is attached to the thumb-turn mounting hole TH by the engaging mechanism 121 before the thumb-turn device 130 is attached to the door 20.

[0023] In the example shown in FIG. 4, the engaging mechanism 121 is configured to be able to apply a force in a direction to expand the thumb-turn mounting hole TH at three locations on the inner peripheral surface of the thumb-turn mounting hole TH. Specifically, the engaging mechanism 121 includes a central engaging member 121C, a left engaging member 121L, and a right engaging member 121R. The central engaging member 121C, the left engaging member 121L, and the right engaging member 121R are all plate-like members formed of a metal such as stainless steel. In the example shown in FIG. 4, the engaging mechanism 121 is configured to have three engaging members, but it may be configured to have one engaging member, two engaging members, or four or more engaging members.

[0024] The body member 122 is a member that constitutes the body of the pedestal 120. In the example shown in FIG. 4, the body member 122 is formed by injection molding resin. A through hole 122A for receiving the thumb turn device 130 is formed in the lower part of the body member 122. Further, a recess 122G for accommodating a part of the engaging member is formed in the rear surface (the surface on the X2 side) of the body member 122. Specifically, the recess 122G includes a central recess 122GC for accommodating a part of the central engaging member 121C, a left recess 122GL for accommodating a part of the left engaging member 121L, and a right recess 122GR for accommodating a part of the right engaging member 121R. Note that each of the central engaging member 121C, the left engaging member 121L, and the right engaging member 121R is configured such that a part thereof protrudes into the through hole 122A and the remaining part is accommodated in the recess 122G.

[0025] The base plate 123 is a member that constitutes the rear surface of the pedestal 120. The base plate 123 is attached to the rear surface of the body member 122 so as to cover at least a part of each of the central engaging member 121C, the ratchet gear 124, the ratchet pawl 125, and the ratchet spring 126 attached to the rear surface of the body member 122. In the example shown in FIG. 4, the base plate 123 is a plate-shaped member formed of a metal such as a highly corrosion-resistant plated steel sheet. A through hole 123A is formed in the lower part of the base plate 123 so as to correspond to the through hole 122A formed in the body member 122.

[0026] Also, in the example shown in FIG. 4, the central engagement member 121C is disposed on the front side (X1 side) of the base plate 123. That is, the central engagement member 121C is disposed between the rear surface of the main body member 122 and the front surface of the base plate 123. On the other hand, the left engagement member 121L and the right engagement member 121R are disposed on the rear side (X2 side) of the base plate 123. That is, the left engagement member 121L and the right engagement member 121R are attached to the rear surface of the base plate 123. Therefore, the base plate 123 has recesses 123G for receiving the left engagement member 121L and the right engagement member 121R, respectively. The recesses 123G are formed by pressing so as to be recessed forward (X1 direction). Specifically, the base plate 123 has a left recess 123GL for receiving a part of the left engagement member 121L and a right recess 123GR for receiving a part of the right engagement member 121R. The left recess 123GL is accommodated in the left recess 122GL formed in the main body member 122 together with a part of the left engagement member 121L, and the right recess 123GR is accommodated in the right recess 122GR formed in the main body member 122 together with a part of the right engagement member 121R.

[0027] The ratchet gear 124 is a member constituting the moving mechanism TM and is also a member constituting the ratchet mechanism LM1. The moving mechanism TM is a mechanism for moving the engagement member in the radial direction of the cam turn mounting hole TH. The ratchet mechanism LM1 is an example of a movement restriction mechanism LM for restricting the moving direction of the engagement member by the moving mechanism TM to one direction. Both the ratchet pawl 125 and the ratchet spring 126 are members for constituting the ratchet mechanism LM1.

[0028] In the example shown in FIG. 4, the ratchet gear 124, the ratchet pawl 125, and the ratchet spring 126 are all formed of a metal such as stainless steel. The ratchet gear 124 and the ratchet pawl 125 are accommodated in the recess 122C formed in the rear surface of the main body member 122. The ratchet spring 126 is accommodated in the groove 122T formed in the rear surface of the main body member 122.

[0029] The screw 127 is an example of a fixing member for fixing the base plate 123 to the main body member 122. This fixing member may be constituted by mechanical elements other than the screw 127. In the example shown in FIG. 4, the base plate 123 is fastened to the rear surface of the main body member 122 by six screws 127.

[0030] The caulking pin 128 is an example of a fixing member for fixing the left engaging member 121L and the right engaging member 121R to the base plate 123. This fixing member may be constituted by mechanical elements other than the caulking pin 128. In the example shown in FIG. 4, the caulking pin 128 is a member formed of a metal such as brass, and includes a left caulking pin 128L for fixing the left engaging member 121L to the base plate 123 and a right caulking pin 128R for fixing the right engaging member 121R to the base plate 123.

[0031] Specifically, the left engaging member 121L is fixed to the base plate 123 by caulking both ends of the left caulking pin 128L inserted through the left through hole 123HL formed in the base plate 123 and the left through hole 121HL formed in the left engaging member 121L. Similarly, the right engaging member 121R is fixed to the base plate 123 by caulking both ends of the right caulking pin 128R inserted through the right through hole 123HR formed in the base plate 123 and the right through hole 121HR formed in the right engaging member 121R.

[0032] In the example shown in FIG. 4, the left engaging member 121L is attached so as to be rotatable with respect to the base plate 123 around the axis AX2 of the left caulking pin 128L, and the right engaging member 121R is attached so as to be rotatable with respect to the base plate 123 around the axis AX3 of the right caulking pin 128R.

[0033] FIG. 4(B) shows, in dotted lines, the state of the left engaging member 121L when it rotates around the axis AX2 and the state of the right engaging member 121R when it rotates around the axis AX3. Specifically, the arrow AR1 shown in dotted lines represents the rotation direction of the left engaging member 121L, and the figures GP1 and GP2 shown in dotted lines represent the positions of the left engaging member 121L after rotation. Also, the arrow AR2 shown in dotted lines represents the rotation direction of the right engaging member 121R, and the figures GP3 and GP4 shown in dotted lines represent the positions of the right engaging member 121R after rotation. In FIG. 4(B), for clarity, the illustration of the base plate 123 is omitted.

[0034] In the illustrated example, the left engaging member 121L and the right engaging member 121R are attached to the base plate 123 so as to be swingable, but they may be attached to the main body member 122 so as to be swingable, or may be swingably clamped between the main body member 122 and the base plate 123.

[0035] Next, referring to FIG. 5, the moving mechanism TM and the ratchet mechanism LM1 will be described. FIG. 5 is a diagram showing a configuration example of the ratchet mechanism LM1. Specifically, FIG. 5(A) is an enlarged view of the range R1 surrounded by the broken line in FIG. 4(B). FIG. 5(B) is a perspective view of the ratchet gear 124. In FIG. 5(A), for clarity, the ratchet spring 126 is schematically shown.

[0036] The moving mechanism TM is a mechanism for moving the engaging member constituting the engaging mechanism 121 in the pedestal 120 attached to the cam turn mounting hole TH in the radial direction of the cam turn mounting hole TH. In the present embodiment, the moving mechanism TM is a rack and pinion mechanism TM1 for moving the central engaging member 121C in the vertical direction (Z-axis direction), which is one of the radial directions of the cam turn mounting hole TH.

[0037] Specifically, the rack and pinion mechanism TM1 is composed of a rack portion RK formed on the central engaging member 121C and the ratchet gear 124.

[0038] As shown in FIG. 5(B), the ratchet gear 124 has a gear portion 124G and a cylindrical portion 124C. The cylindrical portion 124C of the ratchet gear 124 is fitted into a through hole 122H1 (see FIG. 4(A)) formed in the main body member 122 so as to be rotatable with respect to the main body member 122 around the axis AX4. The gear portion 124G is configured to mesh with the rack portion RK of the central engagement member 121C in a state where the cylindrical portion 124C is fitted into the through hole 122H1.

[0039] Further, a hole 124R corresponding to the tip shape of a tool for rotating the ratchet gear 124 is formed in the end face on the front side (X1 side) of the cylindrical portion 124C. In the example shown in FIG. 5, the hole 124R is a cross hole corresponding to the tip shape of a plus driver which is an example of a tool for rotating the ratchet gear 124. Note that the hole 124R may be formed to correspond to the tip shape of other tools such as a minus driver or a hexagon wrench. Alternatively, the cylindrical portion 124C may be configured to have a knob on its front end face so that an operator can manually operate it.

[0040] The ratchet mechanism LM1 is an example of a movement restriction mechanism LM for restricting the movement direction of the engagement member by the movement mechanism TM to one direction. In the present embodiment, the ratchet mechanism LM1 is configured to be able to restrict the downward movement (Z2 direction) of the central engagement member 121C while allowing the upward movement (Z1 direction) of the central engagement member 121C.

[0041] Specifically, the ratchet mechanism LM1 mainly includes a ratchet gear 124, a ratchet pawl 125, and a ratchet spring 126. The ratchet gear 124 and the ratchet pawl 125 are accommodated in a recess 122C formed on the rear surface of the main body member 122.

[0042] The ratchet gear 124 is accommodated in the recess 122C so as to be rotatable around the axis AX4.

[0043] As shown in Fig. 5(A), the ratchet pawl 125 is configured to be rotatable about the axis AX5 of the pin 125P within the recess 122C. The pin 125P is inserted through a through-hole 125H1 formed in the central portion of the ratchet pawl 125 and is configured to be inserted through a through-hole 122H2 (see Fig. 4(A)) formed in the main body member 122. In the present embodiment, the ratchet pawl 125 is fixed to the pin 125P and is configured to rotate together with the pin 125P about the axis AX5. The ratchet pawl 125 and the pin 125P may be coupled, for example, by interference fit. Further, the front end of the pin 125P may be configured to protrude forward from the front surface of the main body member 122 so that an operator can manually rotate it. Alternatively, a hole corresponding to the tip shape of a tool for rotating the pin 125P may be formed in the front end surface of the pin 125P.

[0044] The figure 125A represented by the dotted line in Fig. 5(A) shows the ratchet pawl 125 that rotates about the axis AX5 when the ratchet gear 124 rotates in the direction indicated by the arrow AR11. Further, the figure 125A shows that the engagement between the tip portion 125E of the ratchet pawl 125 and the ratchet gear 124 is released when the ratchet gear 124 rotates in the direction indicated by the arrow AR11.

[0045] As shown in Fig. 5(A), the ratchet spring 126 is housed within a groove 122T formed in the rear surface of the main body member 122. The lower end CT1 of the ratchet spring 126 is fixed to a through-hole 125H2 formed in the ratchet pawl 125, and the upper end CT2 is fixed to the upper end portion of the groove 122T. Note that the through-hole 125H2 is formed between the through-hole 125H1 and the tip portion 125E.

[0046] With this configuration, the ratchet spring 126 generates a force that pulls the tip 125E of the ratchet pawl 125 upward (in the Z1 direction) as indicated by the arrow AR10 in FIG. 5(A). And, as viewed from the rear as shown in FIG. 5(A), the ratchet spring 126 generates a torque that rotates the ratchet pawl 125 counterclockwise about the axis AX5 of the pin 125P.

[0047] When an operator attempts to rotate the ratchet gear 124 in the direction indicated by the arrow AR11 in FIGS. 5(A) and 5(B) using a plus driver, the ratchet pawl 125 rotates in the direction indicated by the arrow AR12 in FIG. 5(A) with the tip 125E being pushed by the second tooth TE2 of the ratchet gear 124.

[0048] At this time, when the engagement between the second tooth TE2 of the ratchet gear 124 and the tip 125E of the ratchet pawl 125 is released, the tip 125E of the ratchet pawl 125 is pulled upward by the ratchet spring 126 and engages with the third tooth TE3 of the ratchet gear 124. When the operator further rotates the ratchet gear 124 in the direction indicated by the arrow AR11, the ratchet pawl 125 further rotates in the direction indicated by the arrow AR11 with the tip 125E being pushed by the third tooth TE3 of the ratchet gear 124. The subsequent movement of the ratchet gear 124 and the ratchet pawl 125 is the same as the above-described movement.

[0049] When the ratchet gear 124 rotates in the direction indicated by the arrow AR11, the central engagement member 121C moves upward (in the Z1 direction) as indicated by the arrow AR13.

[0050] On the other hand, even if the operator attempts to rotate the ratchet gear 124 in the direction indicated by the arrow AR14 in FIGS. 5(A) and 5(B) using a plus driver, the ratchet gear 124 cannot be rotated. Specifically, the operator cannot rotate the ratchet gear 124 in the direction indicated by the arrow AR14 unless the engagement between the tip 125E of the ratchet pawl 125 and the first tooth TE1 of the ratchet gear 124 by the ratchet mechanism LM1 is released.

[0051] When an operator attempts to rotate the ratchet gear 124 in the direction indicated by the arrow AR14 using a plus driver, the ratchet pawl 125 has its tip 125E pressed against the first tooth TE1 of the ratchet gear 124. However, since the rear end 125R of the ratchet pawl 125 is already pressed against the wall surface of the recess 122C, it cannot rotate clockwise in a rear view. Therefore, the central engagement member 121C cannot move downward (in the Z2 direction), which is the direction indicated by the arrow AR15.

[0052] Thus, the ratchet mechanism LM1 is configured to allow counterclockwise rotation of the ratchet gear 124 around the axis AX4 and restrict clockwise rotation of the ratchet gear 124 around the axis AX4 in a rear view as shown in Fig. 5(A). That is, the ratchet mechanism LM1 is configured to allow upward movement of the central engagement member 121C and restrict downward movement of the central engagement member 121C.

[0053] When the operator wants to move the central engagement member 121C downward, that is, when the operator wants to rotate the ratchet gear 124 clockwise around the axis AX4, the engagement between the tip 125E of the ratchet pawl 125 and the first tooth TE1 of the ratchet gear 124 by the ratchet mechanism LM1 may be released.

[0054] Specifically, the operator can rotate the ratchet pawl 125 in the direction indicated by the arrow AR12 by manually rotating the pin 125P configured to rotate with the ratchet pawl 125, and realize a state where the engagement between the tip 125E and the first tooth TE1 is released. Then, with the engagement between the tip 125E and the first tooth TE1 released, the operator can rotate the ratchet gear 124 in the direction indicated by the arrow AR14 using a plus driver, and thereby move the central engagement member 121C downward as shown by the arrow AR15.

[0055] The arrow AR3 represented by the dotted line in FIG. 4(B) represents the moving direction of the central engagement member 121C. The figure GP5 represented by the dotted line represents the position of the central engagement member 121C after moving in the Z2 direction (downward), and the figure GP6 represented by the dotted line represents the position of the central engagement member 121C after moving in the Z1 direction (upward). An operator can move the central engagement member 121C in the vertical direction by rotating the ratchet gear 124 as described above.

[0056] Next, referring to FIG. 6, the engagement mechanism 121 will be described. FIG. 6 is a view showing the engagement mechanism 121 in the pedestal 120 in a state fixed to the thumb turn mounting hole TH. Specifically, FIG. 6(A) is a front view of the engagement mechanism 121 in the pedestal 120 in a state fixed to the thumb turn mounting hole TH. FIG. 6(B) is a cross-sectional view of the central engagement member 121C and the door 20 in a plane parallel to the XZ plane including the dashed-dotted line L3 in FIG. 6(A). Note that the following description relates to the central engagement member 121C, but is similarly applicable to each of the left engagement member 121L and the right engagement member 121R.

[0057] The central engagement member 121C, which is a plate-like member formed of a metal such as stainless steel, is configured to have a base portion BS and a claw portion CL as shown in FIG. 6(B). In the example shown in FIG. 6, the claw portion CL is a portion formed by bending, and is configured such that the angle θ formed between the base portion BS and the claw portion CL is an acute angle less than 90 degrees.

[0058] With this configuration, the central engagement member 121C is arranged such that the rear surface (the surface on the X2 side) of the base portion BS contacts the indoor-side surface 20A of the door 20, and the upper surface (the surface on the Z1 side) of the claw portion CL contacts the edge CE on the rear side (the X2 side) of the inner peripheral surface of the thumb turn mounting hole TH. Therefore, even when a force to pull out the pedestal 120 forward (in the X1 direction) acts on the pedestal 120, the claw portion CL is caught by the edge CE on the rear side (the X2 side) of the inner peripheral surface of the thumb turn mounting hole TH, so the pedestal 120 is not separated from the door 20.

[0059] Further, regardless of the length LT of the thumb turn mounting hole TH, this configuration can bring the upper surface of the claw portion CL into contact with the rear edge CE of the inner peripheral surface of the thumb turn mounting hole TH. Therefore, this configuration has the effect that the engagement mechanism 121 can be applied to thumb turn mounting holes TH having various lengths LT. However, the angle θ formed between the base portion BS and the claw portion CL is not limited to an acute angle and may be 90 degrees or more. Further, the claw portion CL may be formed so as to bend two or more times, or may be formed so as to extend in a curved manner.

[0060] Next, referring to FIG. 7, another configuration example of the pedestal 120 will be described. FIG. 7 is a view showing a pedestal 120A which is another configuration example of the pedestal 120. Specifically, FIG. 7(A) is an exploded perspective view of the pedestal 120A and corresponds to FIG. 4(A). FIG. 7(B) is a rear view of the pedestal 120A and corresponds to FIG. 4(B).

[0061] The pedestal 120A shown in FIG. 7 is different from the pedestal 120 shown in FIG. 4 in that it has a feed screw mechanism TM2 as the movement mechanism TM. The pedestal 120 shown in FIG. 4 has a rack and pinion mechanism TM1 as the movement mechanism TM. Further, the pedestal 120A shown in FIG. 7 is different from the pedestal 120 shown in FIG. 4 in that the movement restriction mechanism LM is omitted. The pedestal 120 shown in FIG. 4 has a ratchet mechanism LM1 as the movement restriction mechanism LM. In other respects, the pedestal 120A shown in FIG. 7 and the pedestal 120 shown in FIG. 4 are common. Therefore, hereinafter, the description of the common parts will be omitted and the different parts will be described in detail.

[0062] The feed screw mechanism TM2 as the movement mechanism TM is mainly composed of a slider 151 and a screw 152.

[0063] The slider 151 is configured to be supported by the main body member 122 so as to be movable in the vertical direction (Z-axis direction) and non-rotatable about the vertical axis (Z-axis). The slider 151 may be formed of metal or resin. In the example shown in FIG. 7, the slider 151 has a substantially rectangular parallelepiped shape and is housed in a corner groove 122S formed in the rear surface (the surface on the X2 side) of the main body member 122. The corner groove 122S is formed so that the slider 151 can slide in the vertical direction and is non-rotatable about the vertical axis (Z-axis). Specifically, the corner groove 122S is configured such that the length in the vertical direction is significantly larger than the length of the slider 151 in the vertical direction. Also, the corner groove 122S is configured such that the length (width) in the left-right direction is substantially the same as the length (width) of the slider 151 in the left-right direction (strictly speaking, the width of the corner groove 122S is slightly larger than the width of the slider 151).

[0064] Also, the slider 151 is configured to be fixed to the upper end of the central engagement member 121C. In the example shown in FIG. 7, the slider 151 has two protruding portions 151T (upper protruding portion 151T1 and lower protruding portion 151T2) protruding rearward from the rear surface. The two protruding portions 151T are configured to be inserted into two through holes 121H (upper through hole 121H1 and lower through hole 121H2) formed in the upper end of the central engagement member 121C.

[0065] The slider 151 is fixed to the central engagement member 121C by caulking the tips of the two protruding portions 151T inserted into the two through holes 121H formed in the upper end of the central engagement member 121C. However, the slider 151 may be fixed to the central engagement member 121C by other means such as an adhesive or screws.

[0066] The screw 152 is configured to engage with the slider 151. In the example shown in FIG. 7, the screw 152 is configured to engage with the female screw hole 151H formed in the slider 151. Specifically, the screw 152 is inserted into the through hole 122H formed in the main body member 122, and is configured such that its tip extends into the angular groove 122S. Then, the screw 152 is screwed into the female screw hole 151H of the slider 151 accommodated in the angular groove 122S.

[0067] In the example shown in FIG. 7, the screw 152 is a metric screw having a cross recess formed in the screw head. The operator can move the slider 151 in the vertical direction within the angular groove 122S by rotating the screw 152 screwed into the female screw hole 151H of the slider 151 with a plus driver. This is because the rotation of the slider 151 about the vertical axis (Z-axis) is restricted by being accommodated in the angular groove 122S.

[0068] Specifically, the operator can move the slider 151 in the direction indicated by arrow AR22 (Z1 direction) by rotating the screw 152 in the direction indicated by arrow AR21 (clockwise direction in top view). Conversely, the operator can move the slider 151 in the direction indicated by arrow AR24 (Z2 direction) by rotating the screw 152 in the direction indicated by arrow AR23 (counterclockwise direction in top view).

[0069] The arrow AR31 represented by the dotted line in FIG. 7(B) represents the moving direction of the central engagement member 121C. The figure GP31 represented by the dotted line represents the position of the central engagement member 121C after moving in the Z2 direction (downward), and the figure GP32 represented by the dotted line represents the position of the central engagement member 121C after moving in the Z1 direction (upward). The operator can move the central engagement member 121C in the vertical direction by rotating the screw 152 as described above. In FIG. 7(B), the illustration of the base plate 123 is omitted for clarity.

[0070] With the above configuration, the pedestal 120A shown in FIG. 7 brings about the same effects as the pedestal 120 shown in FIG. 4. Specifically, the pedestal 120A that constitutes the electronic lock mounting structure FS has a specific effect of enabling the removal of the electronic lock 100 from the door 20 without damaging the indoor surface 20A of the door 20. This is because there is no need to arrange a strong double-sided tape between the indoor surface 20A of the door 20 and the pedestal 120A.

[0071] Furthermore, the pedestal 120A shown in FIG. 7 brings an additional effect that the number of parts can be reduced compared to the pedestal 120 shown in FIG. 4. Also, the pedestal 120A brings an additional effect that the vertical movement of the central engagement member 121C can be facilitated compared to the pedestal 120 having a ratchet mechanism LM1 as the movement restriction mechanism LM. When the pedestal 120A is adopted, the operator can omit operations such as manually operating the ratchet pawl 125 to release the movement restriction by the ratchet mechanism LM1, because the slider 151 (central engagement member 121C) can be moved up and down by simply rotating the screw 152 to one side or the other.

[0072] As described above, the electronic lock mounting structure FS according to the embodiment of the present invention is configured to be disposed between the electronic lock 100 and the door 20 in order to attach the electronic lock 100 to the door 20 as shown in FIG. 1. And the electronic lock mounting structure FS includes an engagement mechanism 121 configured to engage with a thumb turn mounting hole TH provided in the door 20 as shown in FIG. 2.

[0073] With this configuration, the electronic lock mounting structure FS has a specific effect of enabling the removal of the electronic lock 100 from the door 20 without damaging the indoor surface 20A of the door 20. This is because there is no need to arrange a strong double-sided tape between the indoor surface 20A of the door 20 and the electronic lock mounting structure FS.

[0074] The engaging mechanism 121 may include a plurality of claw portions CL formed to engage with the thumb turn mounting hole TH, and a moving mechanism TM configured to be able to move at least one of the plurality of claw portions in the radial direction of the thumb turn mounting hole TH.

[0075] Specifically, as shown in FIGS. 4(A) and 6(B), the engaging mechanism 121 may include three claw portions CL (the claw portion CL of the central engaging member 121C, the claw portion CL of the left engaging member 121L, and the claw portion CL of the right engaging member 121R), and a moving mechanism TM configured to be able to move the claw portion CL of the central engaging member 121C in the Z-axis direction which is one of the radial directions of the thumb turn mounting hole TH.

[0076] More specifically, the moving mechanism TM may be a rack and pinion mechanism TM1 as shown in FIG. 4(A). In this case, the engaging mechanism 121 may include a ratchet mechanism LM1 (see FIG. 4(B)) that restricts the moving direction of the claw portion CL of the central engaging member 121C by the rack and pinion mechanism TM1. Alternatively, the moving mechanism TM may be a feed screw mechanism TM2 as shown in FIG. 7.

[0077] These configurations bring about the effect of being able to increase the mounting strength of the electronic lock unit 10 (pedestal 120) with respect to the door 20 as compared to the case where the electronic lock unit 10 is attached to the door 20 by double-sided tape. Also, these configurations bring about the effect of enabling the pedestal 120 to be attached to thumb turn mounting holes TH having various diameters.

[0078] Also, in order to bring about a similar effect, the claw portion CL of the left engaging member 121L and the claw portion CL of the right engaging member 121R may be swingably attached to the pedestal 120 as shown in FIG. 4(B).

[0079] The three claw portions CL may be arranged at substantially equal intervals along the circumferential direction of the thumb turn mounting hole TH. Specifically, as shown in FIG. 6(A), the claw portions CL of the central engagement member 121C, the left engagement member 121L, and the right engagement member 121R may be arranged at intervals of approximately 120 degrees along the circumferential direction of the substantially circular thumb turn mounting hole TH. By arranging the points (three contact points) where the thumb turn mounting hole TH and the engagement mechanism 121 come into contact in a well-balanced manner around the center point of the thumb turn mounting hole TH, the mounting strength of the electronic lock unit 10 (pedestal 120) to the door 20 is increased. Therefore, when the engagement mechanism 121 has two claw portions, these two claw portions are preferably arranged at intervals of approximately 180 degrees along the circumferential direction of the thumb turn mounting hole TH. Alternatively, when the engagement mechanism 121 has four claw portions, these four claw portions are preferably arranged at intervals of approximately 90 degrees along the circumferential direction of the thumb turn mounting hole TH.

[0080] At least one of the plurality of claw portions CL may be configured to engage with the rear edge of the inner peripheral surface of the thumb turn mounting hole TH. For example, each of the three claw portions CL (the claw portion CL of the central engagement member 121C, the claw portion CL of the left engagement member 121L, and the claw portion CL of the right engagement member 121R) may be bent with respect to the base portion BS such that the angle θ formed between the claw portion CL and the base portion BS is an acute angle, as shown in FIG. 6(B), and may be configured to contact the rear edge CE of the inner peripheral surface of the thumb turn mounting hole TH.

[0081] This configuration has the effect of increasing the mounting strength of the electronic lock unit 10 (pedestal 120) to the door 20 compared to the case where the claw portion CL is bent perpendicular to the base portion BS and the claw portion CL contacts the inner peripheral surface of the thumb turn mounting hole TH.

[0082] Next, referring to FIGS. 8 to 10, an electronic lock unit 10A, which is another configuration example of the electronic lock unit 10, will be described. FIGS. 8 to 10 are front perspective views of the electronic lock unit 10A. As shown in FIG. 10, the electronic lock unit 10A is composed of an electronic lock 100 and a pedestal 120. In the example shown in FIGS. 8 to 10, the attachment 110 in FIG. 2 of the above-described embodiment is omitted. Therefore, the electronic lock attachment structure FS for attaching the electronic lock 100 to the door 20 is constituted by the pedestal 120.

[0083] Specifically, as shown in FIG. 9, the pedestal 120 includes an engagement mechanism 121, a slide cover SC as a body member 122, and a base plate 123. The engagement mechanism 121 includes, as an engagement member, a claw portion NP1 of an adjustment plate AP and a claw portion NP2 of the base plate 123.

[0084] As shown in FIG. 9, the adjustment plate AP is a member that constitutes a movement mechanism TM for moving a claw portion NP1, which is an engagement member attached to the thumb turn mounting hole TH, in the radial direction of the thumb turn mounting hole TH. Details of the movement mechanism TM will be described later. Further, the adjustment plate AP is a member that constitutes an attachment unit for attaching the pedestal 120 to the door 20.

[0085] As shown in FIGS. 8 to 10, the electronic lock unit 10A is attached to the door 20. Hereinafter, the procedure for an operator to attach the electronic lock unit 10A to the door will be described.

[0086] Specifically, as shown in FIG. 8, first, the operator removes the thumb turn device 130 from the door 20 to expose the thumb turn mounting hole TH formed in the indoor-side surface 20A of the door 20.

[0087] Then, as shown in FIG. 9, the operator inserts the claw portion NP1 of the adjustment plate AP and the claw portion NP2 of the base plate 123 into the thumb turn mounting hole TH.

[0088] After that, the operator tightens the screw S3, which is a component of the moving mechanism TM, and presses the claw portion NP1 and the claw portion NP2 against the inner peripheral surface of the cam turn mounting hole TH, thereby fixing the adjustment plate AP and the base plate 123 to the door 20. After that, the operator attaches the cam turn device 130 to the door 20. That is, the operator attaches the cam turn device 130 again to the cam turn mounting hole TH to which the adjustment plate AP and the base plate 123 are fixed.

[0089] After that, as shown in FIG. 8, the operator fixes the slide cover SC to the main body of the electronic lock 100 with four screws S1. A spacer for adjusting the distance between the clamping mechanism SM and the cam turn device 130 in the X-axis direction may be disposed between the slide cover SC and the main body of the electronic lock 100. After that, the operator attaches the slide cover SC fixed to the main body of the electronic lock 100 to the base plate 123. The slide cover SC is slidably fitted to the base plate 123.

[0090] After that, as shown in FIG. 9, the operator visually aligns the rotation center axis AX6 of the thumb turn device 130 with the rotation axis AX7 of the clamping mechanism SM (drive unit) of the electronic lock 100 and tightens the screw S2, thereby fixing the slide cover SC to the base plate 123. At this time, since the fixing hole LH of the base plate 123 through which the screw S2 is inserted is a long hole in the vertical direction (Z-axis direction), the fixing position of the slide cover SC can be adjusted in the vertical direction (Z-axis direction). That is, the fixing position of the slide cover SC can be adjusted in the vertical direction (Z-axis direction) by the adjustment mechanism AM including the screw S2 and the fixing hole LH. The details of the adjustment mechanism AM will be described later. Therefore, the operator can move the electronic lock 100 in the vertical direction (Z-axis direction) with respect to the thumb turn device 130 in a state where the slide cover SC is slidably engaged with the base plate 123, and can arrange the rotation axis AX7 of the clamping mechanism SM (drive unit) of the electronic lock 100 at an appropriate position. That is, the operator can align the rotation center axis AX6 of the thumb turn device 130 with the rotation axis AX7 of the clamping mechanism SM (drive unit). FIG. 10 shows the state of the electronic lock unit 10A when the rotation center axis AX6 of the thumb turn device 130 coincides with the rotation axis AX7 of the clamping mechanism SM (drive unit).

[0091] Next, referring to FIGS. 11 and 12, the adjustment mechanism AM will be described. FIGS. 11 and 12 are diagrams showing a configuration example of the adjustment mechanism AM. Specifically, FIG. 11(A) is a top view of the adjustment plate AP, the base plate 123, the cover plate CP, and the slide cover SC. FIG. 11(B) shows a cross section of each member in a plane parallel to the XZ plane including the dashed line L4 in FIG. 11(A). Note that in FIG. 11(B), for clarity, the illustration of the compression spring SP shown in FIG. 11(A) is omitted. FIG. 12(A) is a perspective view of the electronic lock unit. FIG. 12(B) shows a cross section of each member in a plane parallel to the XY plane including the dashed line L5 in FIG. 11(A).

[0092] By rotating the screw S3, the operator can move the adjustment plate AP in the vertical direction (Z-axis direction) within the cover plate CP as indicated by the arrow AR41 in Fig. 11(B) and the arrow AR42 in Fig. 12(A). Then, the operator can move the adjustment plate AP so that the claw portions NP1 and NP2 are pressed against the inner peripheral surface of the thumb turn mounting hole TH.

[0093] That is, the screw S3, the cover plate CP, and the adjustment plate AP constitute a feed screw mechanism TM3 as a movement mechanism TM for moving the engaging member (claw portion NP1) in the radial direction of the thumb turn mounting hole TH. The details of the feed screw mechanism TM3 will be described later.

[0094] The effects of adjusting the fixed position of the main body of the electronic lock 100 in the vertical direction (Z-axis direction) are as follows.

[0095] If the rotation center axis AX6 of the thumb turn device 130 and the rotation axis AX7 of the clamping mechanism SM (drive unit) are misaligned, the drive load of the drive unit may increase and the battery life may decrease. Also, if such an axis misalignment is extremely large, there is a possibility that the thumb turn device 130 cannot be rotated by the force of the motor.

[0096] The hole diameter of the thumb turn mounting hole TH varies depending on the type of the thumb turn device 130. However, the operator can attach the electronic lock unit 10A to the thumb turn mounting hole TH having various hole diameters by movably adjusting the adjustment plate AP having the claw portion NP1.

[0097] However, since the position of the claw portion NP2 of the base plate 123 is fixed (non-adjustable), the positional relationship between the center of the thumb turn mounting hole TH and the base plate 123 (the center of the through hole 123A) changes depending on the size of the aperture of the thumb turn mounting hole TH. And when the fixing hole LH (see FIG. 9) of the base plate 123 is composed of a single simple round hole (single round hole), the electronic lock 100 (clamping mechanism SM) cannot be relatively moved in the vertical direction (Z-axis direction) with respect to the base plate 123. This is because when the fixing hole LH is composed of a single round hole, the relative position of the electronic lock 100 (clamping mechanism SM) with respect to the base plate 123 is uniquely determined by the position of the fixing hole LH. Therefore, when the electronic lock unit 10A is attached to the thumb turn mounting hole TH having an aperture different from the aperture of the thumb turn mounting hole TH when the rotation center axis AX6 of the thumb turn device 130 and the rotation axis AX7 of the clamping mechanism SM (drive unit) coincide, the rotation center axis AX6 of the thumb turn device 130 and the rotation axis AX7 of the clamping mechanism SM (drive unit) will be displaced.

[0098] The adjustment mechanism AM is configured to suppress or prevent such displacement. Specifically, the adjustment mechanism AM has a fixing hole LH formed as an oblong hole instead of a simple round hole. Therefore, the operator can slide the slide cover SC in the vertical direction with respect to the base plate 123 so as to be able to align with the thumb turn mounting hole TH having various apertures.

[0099] Also, when the knob 132 of the thumb turn device 130 is provided eccentrically with respect to the main body 133 of the thumb turn device 130 (corresponding to the pedestal 131 in FIG. 1(C)), that is, when the thumb turn device 130 is attached to the thumb turn mounting hole TH such that the rotation center axis AX6 of the thumb turn device 130 does not pass through the center of the thumb turn mounting hole TH, the same problem as above occurs. The adjustment mechanism AM is configured such that the attachment position of the electronic lock 100 can be adjusted so as to be able to cope with such a problem without increasing the variations of the base plate 123, that is, without preparing a plurality of different base plates.

[0100] Next, referring to FIG. 13, the fixing hole LH of the base plate 123 will be described. FIG. 13 is a perspective view of the base plate 123. Specifically, FIG. 13(A) is a perspective view of the base plate 123 having a fixing hole LH which is an elongated hole formed by connecting a plurality of round holes. FIG. 13(B) is a perspective view of the base plate 123 having a fixing hole LH1 which is an oblong hole.

[0101] In order to fix the slide cover SC to the base plate 123 using the screw S2 in a state where the rotation center axis AX6 of the thumb turn device 130 and the rotation axis AX7 of the clamping mechanism SM (drive unit) are aligned, a fixing hole LH through which the screw S2 passes is formed in the base plate 123. After the operator adjusts the position of the main body of the electronic lock 100 assembled to the slide cover SC with respect to the position of the thumb turn device 130, the slide cover SC is fixed to the base plate 123 with the left and right screws S2.

[0102] The fixing hole LH shown in FIG. 13(A) is an elongated hole (continuous round holes) in a state where a plurality of round holes are connected, and since the connecting portion of the fixing hole LH has a smaller diameter than the screw S2, even if the screw S2 loosens, the screw S2 will not move in the vertical direction (Z-axis direction) within the fixing hole LH. This configuration can prevent the main body of the electronic lock 100 from sliding within the range of the length of the fixing hole LH in the vertical direction (Z-axis direction) when the screw S2 loosens due to some factor such as aging. Therefore, the fixing hole LH can suppress the deviation between the rotation center axis AX6 of the thumb turn device 130 and the rotation axis AX7 of the clamping mechanism SM (drive unit), and can suppress an increase in the driving load due to the axial deviation. However, as shown in FIG. 13(B), the fixing hole LH may be formed as a fixing hole LH1 which is an oblong hole.

[0103] In the example shown in FIG. 13(B), the fixing of the slide cover SC to the base plate 123 is realized not by the fitting of the screw S2 and the fixing hole LH as shown in FIG. 13(A), but by fastening the slide cover SC and the base plate 123 with the screw S2. Therefore, the example shown in FIG. 13(B) has the effect that the fixing position of the slide cover SC with respect to the base plate 123 can be adjusted steplessly. Note that the example shown in FIG. 13(A) is configured such that the fixing position of the slide cover SC with respect to the base plate 123 can be adjusted stepwise.

[0104] Further, the screw S2 (bolt) constituting the adjustment mechanism AM is configured to engage with a nut N1 fixed to the slide cover SC (see also FIGS. 8 and 11(A)) as shown in FIG. 12(B), for example. However, the screw S2 may be configured to engage with a female screw portion integrated with the slide cover SC.

[0105] Also, the screw S2 used for fitting with the fixing hole LH shown in FIG. 13(A) may be replaced with a pin. In this case, the fastening of the slide cover SC and the base plate 123 may be realized by any other fastening member such as a clamp mechanism.

[0106] Similarly, the nut N1 and the screw S2 used for fastening the slide cover SC and the base plate 123 in FIG. 13(B) may be replaced with any other fastening member such as a clamp mechanism.

[0107] Also, in the example shown in FIG. 13(A), the fixing hole LH (continuous round hole) is formed in the base plate 123, and a through hole RH (see FIGS. 8 and 12(B)), which is a single round hole for passing the screw S2, is formed in the slide cover SC. However, the fixing hole LH (continuous round hole) may be formed in the slide cover SC. In this case, a single round hole for passing the screw S2 may be formed in the base plate 123. Alternatively, fixing holes LH (continuous round holes) may be formed in each of the base plate 123 and the slide cover SC. The same applies to the fixing hole LH1 (oblong hole) shown in FIG. 13(B).

[0108] Next, referring to FIGS. 14 and 15, the feed screw mechanism TM3 will be described. FIG. 14 is a diagram showing a configuration example of the feed screw mechanism TM3. FIG. 15 is a diagram showing a main part of the feed screw mechanism TM3 shown in FIG. 14. Specifically, FIG. 14 is a perspective view of the base plate 123 with the feed screw mechanism TM3 including a cover plate CP, an adjustment plate AP, a slider N2, a screw S3, and a compression spring SP assembled thereto. FIG. 15 is a perspective view of the main part of the feed screw mechanism TM3 shown in FIG. 14, showing a state in which the illustration of the cover plate CP and the base plate 123 in FIG. 14 is omitted. In FIG. 14, for clarity, a coarse dot pattern is attached to the adjustment plate AP, a fine dot pattern is attached to the screw S3, and a cross pattern is attached to the cover plate CP. Also, in FIG. 15, for clarity, a coarse dot pattern is attached to the adjustment plate AP, a fine dot pattern is attached to the screw S3, and an even finer dot pattern is attached to the slider N2.

[0109] The slider N2 is supported by an adjustment plate AP so as to be movable in the vertical direction (Z-axis direction) and non-rotatable about the vertical axis (Z-axis). In the example shown in FIG. 15, the slider N2 is a nut having a substantially rectangular parallelepiped shape and is accommodated in a space surrounded by a front wall portion FW, an upper wall portion UW, a rear wall portion BW, a lower left wall portion DLW, and a lower right wall portion DRW of the adjustment plate AP. The front wall portion FW is configured to restrict the movement of the slider N2 in the forward direction (X1 direction), the upper wall portion UW is configured to restrict the movement of the slider N2 in the upward direction (Z1 direction), the rear wall portion BW is configured to restrict the movement of the slider N2 in the rearward direction (X2 direction), and the lower left wall portion DLW and the lower right wall portion DRW are configured to restrict the movement of the slider N2 in the downward direction (Z2 direction). Further, the front wall portion FW and the rear wall portion BW are configured to be able to restrict the rotation of the slider N2 about the vertical axis (Z-axis).

[0110] The lower left wall portion DLW is formed by bending an upper side (Z1 side) portion of the left wall portion LW of the adjustment plate AP to the right (Y2 direction), and the lower right wall portion DRW is formed by bending an upper side (Z1 side) portion of the right wall portion RW of the adjustment plate AP to the left (Y1 direction). Further, the front wall portion FW is formed by bending a front side (X1 side) portion of the upper wall portion UW downward (Z2 direction).

[0111] The upper wall portion UW is formed by bending an upper side (Z1 side) portion of the rear wall portion BW forward (X1 direction), the left wall portion LW is formed by bending a left side (Y1 side) portion of the rear wall portion BW forward (X1 direction), and the right wall portion RW is formed by bending a right side (Y2 side) portion of the rear wall portion BW forward (X1 direction).

[0112] As shown in FIG. 14, the screw S3 has its screw head SH supported by the upper surface (Z1 side surface) of a support plate SB which is a part of the base plate 123, and is configured to be screwed into a female screw hole formed in the central portion of the slider N2. Further, the screw S3 is disposed within the compression spring SP so as to penetrate the compression spring SP.

[0113] In the illustrated example, the screw S3 is a metric screw having a cross-shaped hole formed in the screw head. The operator can move the slider N2 in the vertical direction (Z-axis direction) within the cover plate CP by rotating the screw S3 screwed into the female screw hole of the slider N2 with a plus driver.

[0114] The compression spring SP is disposed between the lower surface (the surface on the Z2 side) of the support plate SB which is a part of the base plate 123 and the upper surface (the surface on the Z1 side) of the upper wall portion UW of the adjustment plate AP in a state of being penetrated by the screw S3.

[0115] When the screw S3 is rotated in one direction around the axis, the slider N2 moves in the direction approaching the screw head SH (Z1 direction) because the rotation of the slider N2 is restricted by the front wall portion FW and the rear wall portion BW of the adjustment plate AP. This is because the rotational movement of the screw S3 is converted into the linear movement of the slider N2. At this time, the adjustment plate AP is pushed by the lower surface (the surface on the Z2 side) of the upper wall portion UW by the slider N2 moving in the Z1 direction and moves in the Z1 direction together with the slider N2. The compression spring SP is further compressed because the distance between the support plate SB of the base plate 123 and the upper wall portion UW of the adjustment plate AP becomes shorter.

[0116] When the screw S3 is rotated in the other direction around the axis, the slider N2 moves in the direction away from the screw head SH (Z2 direction). At this time, the adjustment plate AP moves in the Z2 direction together with the slider N2 because the upper surface (the surface on the Z1 side) of the upper wall portion UW is biased downward (Z2 direction) by the compression spring SP and pressed against the upper surface (the surface on the Z1 side) of the slider N2.

[0117] The compression spring SP can always press the lower surface (the surface on the Z2 side) of the upper wall portion UW of the adjustment plate AP against the upper surface (the surface on the Z1 side) of the slider N2. Therefore, the compression spring SP can cause the movement of the adjustment plate AP to follow the movement of the slider N2 whether the slider N2 moves upward (Z1 direction) or downward (Z2 direction).

[0118] Specifically, the operator can move the slider N2 and the adjustment plate AP in the direction indicated by arrow AR52 (Z1 direction) by rotating the screw S3 in the direction indicated by arrow AR51 (clockwise direction in top view). Conversely, the operator can move the slider N2 and the adjustment plate AP in the direction indicated by arrow AR54 (Z2 direction) by rotating the screw S3 in the direction indicated by arrow AR53 (counterclockwise direction in top view).

[0119] As shown in FIG. 11(B), the screw S3 is arranged to be inclined with respect to the Z-axis direction. Specifically, the screw S3 is arranged to form an angle α with respect to the Z-axis direction. This configuration has the effect of making it easier for the operator to rotate the screw S3 around its axis using a tool such as a plus driver because the screw head SH of the screw S3 can be tilted forward. Also, compared to the case where the screw S3 is arranged to be parallel to the Z-axis direction, when the slider N2 is brought closer to the screw head SH by rotating the screw S3 and the claw portion NP1 is pressed against the inner peripheral surface of the thumb turn mounting hole TH, it has the effect of increasing the force pressing the adjustment plate AP against the surface 20A (see FIG. 8) of the door 20. That is, this configuration has the effect of increasing the mounting strength of the electronic lock unit 10A to the door 20.

[0120] Also, as shown in FIG. 15, a through hole WH is provided in the rear wall portion BW of the adjustment plate AP at a position corresponding to the tip portion SE of the screw S3. This configuration has the effect of preventing the tip portion SE from coming into contact with the rear wall portion BW.

[0121] Further, as shown in FIG. 14, the cover plate CP is provided with a through hole QH in the front plate portion FP. The through hole QH is configured to have a width larger than the length (width) of the front wall portion FW of the adjustment plate AP in the Y-axis direction. Further, the through hole QH is configured to have a length larger than the movable range of the front wall portion FW in the Z-axis direction. This configuration has the effect of preventing the front wall portion FW of the adjustment plate AP from contacting the front plate portion FP of the cover plate CP. Specifically, when the slider N2 is moved in a direction approaching the screw head SH of the screw S3, the upper wall portion UW of the adjustment plate AP is bent by the slider N2 in a direction approaching the screw head SH, and as a result, even when the front wall portion FW moves forward (in the X1 direction), this configuration has the effect of preventing the front wall portion FW from contacting the front plate portion FP. Therefore, this configuration can surely prevent the front wall portion FW from contacting the front plate portion FP and hindering the upward movement (in the Z1 direction) of the adjustment plate AP.

[0122] Also, in the illustrated example, the adjustment plate AP is configured such that the distance between the outer surface (the surface on the Y1 side) of the left wall portion LW and the outer surface (the surface on the Y2 side) of the right wall portion RW is slightly smaller than the distance between the inner surface (the surface on the Y2 side) of the left plate portion LP and the inner surface (the surface on the Y1 side) of the right plate portion RP of the cover plate CP. This configuration has the effect of preventing the moving direction of the adjustment plate AP from deviating greatly from the Z-axis direction when the adjustment plate AP moves in the Z-axis direction. That is, the cover plate CP can guide the movement of the adjustment plate AP in the Z-axis direction. This is because when the moving direction of the adjustment plate AP deviates from the Z-axis direction, the left wall portion LW or the right wall portion RW of the adjustment plate AP contacts the left plate portion LP or the right plate portion RP of the cover plate CP.

[0123] Next, referring to FIG. 16, a configuration example of the engagement mechanism 121 will be described. FIG. 16 is a bottom view of the engagement mechanism 121. Specifically, FIGS. 16(A1) to 16(A3) show a configuration example of the engagement mechanism 121A including two claw portions (claw portion NP1 and claw portion NP2), and FIGS. 16(B1) to 16(B3) show a configuration example of the engagement mechanism 121B including three claw portions (claw portion NP1, claw portion NP2, and claw portion NP3).

[0124] More specifically, FIG. 16(A1) shows the engagement mechanism 121A attached to the thumb turn mounting hole TH1 having a predetermined diameter, and FIG. 16(B1) shows the engagement mechanism 121B attached to the thumb turn mounting hole TH1. In FIGS. 16(A1) and 16(B1), for clarity, the thumb turn mounting hole TH1 is shown by a dashed-dotted line.

[0125] FIG. 16(A2) shows the engagement mechanism 121A attached to the thumb turn mounting hole TH2 having a diameter larger than that of the thumb turn mounting hole TH1, and FIG. 16(B2) shows the engagement mechanism 121B attached to the thumb turn mounting hole TH2. In FIGS. 16(A2) and 16(B2), for clarity, the thumb turn mounting hole TH1 as a comparison target is shown by a dashed-dotted line, and the thumb turn mounting hole TH2 is shown by a broken line.

[0126] FIG. 16(A3) shows the engagement mechanism 121A attached to the thumb turn mounting hole TH3 having a diameter smaller than that of the thumb turn mounting hole TH1, and FIG. 16(B3) shows the positional relationship between the thumb turn mounting hole TH3 and the engagement mechanism 121B. In FIGS. 16(A3) and 16(B3), for clarity, the thumb turn mounting hole TH1 as a comparison target is shown by a dashed-dotted line, and the thumb turn mounting hole TH3 is shown by a broken line.

[0127] An example of the engagement mechanism 121, the engagement mechanism 121A, includes a claw portion NP1 integrally formed on the adjustment plate AP and a claw portion NP2 integrally formed on the base plate 123, as shown in FIG. 16(A1).

[0128] The claw part NP1 and the claw part NP2 are arranged on the circumference of the swivel mounting hole TH1 with an interval of 180 degrees from each other so as to face each other with the rotation center axis AX6 (see FIG. 11(A)) of the swivel device 130 interposed therebetween in the vertical direction (Z-axis direction).

[0129] The claw part NP1 includes a central part N1C that curves along the circumference of the swivel mounting hole TH1, a left end part N1L that curves outward so as to contact the inner peripheral surface of the swivel mounting hole TH1, and a right end part N1R that curves outward so as to contact the inner peripheral surface of the swivel mounting hole TH. Similarly, the claw part NP2 includes a central part N2C that curves along the circumference of the swivel mounting hole TH1, a left end part N2L that curves outward so as to contact the inner peripheral surface of the swivel mounting hole TH, and a right end part N2R that curves outward so as to contact the inner peripheral surface of the swivel mounting hole TH1.

[0130] However, the left end part N1L and the right end part N1R of the claw part NP1 may be omitted. In this case, the central part N1C of the claw part NP1 has a portion that curves outward so as to contact the inner peripheral surface of the swivel mounting hole TH. Also, the claw part NP1 may be configured like the claw part CL of the central engagement member 121C shown in FIG. 6. The same applies to the claw part NP2.

[0131] Another example of the engagement mechanism 121, the engagement mechanism 121B, includes a claw part NP1 integrally formed on the adjustment plate AP and claw parts NP2 and NP3 integrally formed on the base plate 123, as shown in FIG. 16(B1).

[0132] The claw part NP1, the claw part NP2, and the claw part NP3 are arranged on the circumference of the swivel mounting hole TH1 with an interval of 120 degrees from each other.

[0133] The claw portion NP1 includes a central portion N1C that curves along the circumference of the thumb turn mounting hole TH1, a left end portion N1L that curves outward to contact the inner peripheral surface of the thumb turn mounting hole TH1, and a right end portion N1R that curves outward to contact the inner peripheral surface of the thumb turn mounting hole TH. Also, the claw portion NP2 includes a central portion N2C that curves along the circumference of the thumb turn mounting hole TH1, a left end portion N2L that curves outward to contact the inner peripheral surface of the thumb turn mounting hole TH, and a right end portion N2R that curves outward to contact the inner peripheral surface of the thumb turn mounting hole TH1. Similarly, the claw portion NP3 includes a central portion N3C that curves along the circumference of the thumb turn mounting hole TH1, a left end portion N3L that curves outward to contact the inner peripheral surface of the thumb turn mounting hole TH, and a right end portion N3R that curves outward to contact the inner peripheral surface of the thumb turn mounting hole TH1.

[0134] However, the left end portion N1L and the right end portion N1R of the claw portion NP1 may be omitted. In this case, the central portion N1C of the claw portion NP1 has a portion that curves outward to contact the inner peripheral surface of the thumb turn mounting hole TH. Also, the claw portion NP1 may be configured like the claw portion CL of the central engagement member 121C shown in FIG. 6. The same applies to the claw portion NP2 and the claw portion NP3.

[0135] When the engagement mechanism 121A is attached to the thumb turn mounting hole TH1 as shown in FIG. 16(A1), the left end portion N1L and the right end portion N1R of the claw portion NP1 contact the inner peripheral surface of the thumb turn mounting hole TH1, and the left end portion N2L and the right end portion N2R of the claw portion NP2 contact the inner peripheral surface of the thumb turn mounting hole TH1, and it is arranged in the thumb turn mounting hole TH1.

[0136] The same applies when attaching to the thumb turn mounting hole TH2 as shown in FIG. 16(A2) and when attaching to the thumb turn mounting hole TH3 as shown in FIG. 16(A3).

[0137] That is, the engagement mechanism 121A is configured to be attachable to any of the three thumb turn mounting holes with different diameters.

[0138] On the one hand, when the engagement mechanism 121B is attached to the thumb turn mounting hole TH1 as shown in Fig. 16(B1), the left end N1L and the right end N1R of the claw portion NP1 contact the inner peripheral surface of the thumb turn mounting hole TH1, and the left end N2L and the right end N2R of the claw portion NP2 contact the inner peripheral surface of the thumb turn mounting hole TH1, and the left end N3L and the right end N3R of the claw portion NP3 contact the inner peripheral surface of the thumb turn mounting hole TH1, and it is arranged in the thumb turn mounting hole TH1.

[0139] Therefore, the engagement mechanism 121B that provides six-point contact can achieve higher mounting strength compared to the engagement mechanism 121A that provides four-point contact.

[0140] However, when attached to the thumb turn mounting hole TH2 as shown in Fig. 16(B2), the engagement mechanism 121B has the left end N1L and the right end N1R of the claw portion NP1 contacting the inner peripheral surface of the thumb turn mounting hole TH2, but for the claw portion NP2, only the left end N2L contacts the inner peripheral surface of the thumb turn mounting hole TH2, and for the claw portion NP3, only the right end N3R contacts the inner peripheral surface of the thumb turn mounting hole TH2, and it is arranged in the thumb turn mounting hole TH2.

[0141] That is, when the engagement mechanism 121B is arranged in the thumb turn mounting hole TH2, the right end N2R of the claw portion NP2 and the left end N3L of the claw portion NP3 do not contact the inner peripheral surface of the thumb turn mounting hole TH2 and are in a state of floating upward from the inner peripheral surface.

[0142] Therefore, in the combination of the engagement mechanism 121B and the thumb turn mounting hole TH2, the engagement mechanism 121B cannot achieve high mounting strength by six-point contact. Also, in the combination of the engagement mechanism 121B and the thumb turn mounting hole TH2, the right end N2R and the left end N3L may interfere with the pedestal 131 of the thumb turn device 130 as shown in Fig. 16(B2). In Fig. 16(B2), the contour of the pedestal 131 of the thumb turn device 130 is shown by a two-dot chain line.

[0143] These problems can be solved by configuring the claw portions NP2 and NP3 to be swingable with respect to the base plate 123, such as the left engaging member 121L and the right engaging member 121R shown in FIG. 4(B).

[0144] Also, when attaching to the thumb turn mounting hole TH3 as shown in FIG. 16(B3), even if the engaging mechanism 121B can bring the claw portion NP1 into contact with the inner peripheral surface of the thumb turn mounting hole TH3, the claw portions NP2 and NP3 cannot be brought into contact with the inner peripheral surface of the thumb turn mounting hole TH3.

[0145] For example, when trying to bring the left end portion N2L of the claw portion NP2 into contact with the inner peripheral surface of the thumb turn mounting hole TH3, the right end portion N2R of the claw portion NP2 interferes with the edge of the thumb turn mounting hole TH3. Or, when trying to bring the right end portion N3R of the claw portion NP3 into contact with the inner peripheral surface of the thumb turn mounting hole TH3, the left end portion N3L of the claw portion NP3 interferes with the edge of the thumb turn mounting hole TH3.

[0146] These problems can be solved by configuring the claw portions NP2 and NP3 to be swingable with respect to the base plate 123, such as the left engaging member 121L and the right engaging member 121R shown in FIG. 4(B).

[0147] As described above, the engaging mechanism 121A including two claw portions brings about the effect that it can more flexibly respond to thumb turn mounting holes having various diameters compared to the engaging mechanism 121B including three claw portions. That is, even if the engaging mechanism 121A does not have swingable claw portions, it can flexibly respond to each of a plurality of thumb turn mounting holes having various diameters.

[0148] As described above, the electronic lock mounting structure FS according to the embodiment of the present invention is configured to be disposed between the electronic lock 100 and the door 20 in order to attach the electronic lock 100 to the door 20 as shown in FIGS. 8 to 10. The electronic lock mounting structure FS includes an engagement mechanism 121 configured to engage with a thumb turn mounting hole TH provided in the door 20, and an adjustment mechanism AM configured to adjust the mounting position of the electronic lock 100 with respect to the thumb turn device 130.

[0149] With this configuration, the electronic lock mounting structure FS can remove the electronic lock 100 from the door 20 without damaging the indoor surface 20A of the door 20. In addition to this specific effect, it is possible to suppress the deviation between the rotation center axis AX6 of the thumb turn device 130 and the rotation axis AX7 of the clamping mechanism SM (drive unit), and an additional effect of suppressing an increase in the drive load due to the axial deviation can be obtained.

[0150] As shown in FIG. 8, the adjustment mechanism AM may include a base plate 123, a slide cover SC movably attached to the base plate 123 in a direction (Z-axis direction) perpendicular to the rotation center axis AX6 of the thumb turn device 130, and a fastening member for fastening the base plate 123 and the slide cover SC.

[0151] As shown in FIG. 8, the fastening member may include a screw S2 passing through a fixing hole LH as a first hole provided in the base plate 123 and a through hole RH as a second hole provided in the slide cover SC.

[0152] At least one of the first hole (fixing hole LH) and the second hole (through hole RH) may be a continuous round hole or an oblong hole. In the example shown in FIG. 13(A), the fixing hole LH as the first hole is a continuous round hole, and in the example shown in FIG. 13(B), the fixing hole LH1 as the first hole is an oblong hole. Note that the fixing hole LH may be composed of a plurality of separate round holes arranged at intervals from each other.

[0153] Further, the electronic lock attachment structure FS may include a movement mechanism TM configured to be able to move at least one of a plurality of claw portions formed to engage with the thumb turn attachment hole TH in the radial direction of the thumb turn attachment hole TH. In the example shown in FIG. 11, the electronic lock attachment structure FS includes a feed screw mechanism TM3 as a movement mechanism TM configured to be able to move a claw portion NP1, which is one of two claw portions NP1 and NP2 formed to engage with the thumb turn attachment hole TH, in the radial direction (Z-axis direction) of the thumb turn attachment hole TH.

[0154] The feed screw mechanism TM3 shown in FIG. 11 may be replaced with another movement mechanism TM such as the rack and pinion mechanism TM1 shown in FIG. 4 or the feed screw mechanism TM2 shown in FIG. 7.

[0155] Further, the electronic lock attachment structure FS may include a movement restriction mechanism that restricts the movement direction of the claw portion by the movement mechanism TM. For example, in the example shown in FIG. 4, the electronic lock attachment structure FS may include a ratchet mechanism LM1 as a movement restriction mechanism LM that restricts the movement direction of the claw portion CL of the central engagement member 121C by the rack and pinion mechanism TM1, which is an example of the movement mechanism TM.

[0156] This configuration has the effect of being able to restrict the downward movement (Z2 direction) while allowing the upward movement (Z1 direction) of the claw portion CL of the central engagement member 121C. Therefore, this configuration can surely prevent the claw portion from moving downward and the engagement mechanism 121 from falling out of the thumb turn attachment hole TH after the engagement mechanism 121 is attached to the thumb turn attachment hole TH.

[0157] Also, the movement mechanism TM shown in each of FIGS. 4, 7, and 9 may be a feed screw mechanism TM3. In this case, the feed screw mechanism TM3 may include a compression spring SP that biases the claw portion NP1 in one of the radial directions (Z2 direction) of the thumb turn attachment hole TH.

[0158] As shown in FIG. 15, this configuration has the effect that, no matter in which direction the screw S3, which is a component of the feed screw mechanism TM3, is rotated around its axis, the claw portion NP1 can be moved in the Z-axis direction by a distance corresponding to the rotation angle. That is, it is possible to prevent the problem that only the screw S3 moves without the claw portion NP1 moving.

[0159] Also, as shown in FIG. 11, the plurality of claw portions may be composed of a first claw portion (claw portion NP2) and a second claw portion (claw portion NP1) that can move in a direction (Z-axis direction) perpendicular to the rotation center axis AX6 of the swivel device 130 with respect to the first claw portion (claw portion NP2). In this case, the first claw portion (claw portion NP2) and the second claw portion (claw portion NP1) are preferably arranged to face each other with the center of the swivel mounting hole TH therebetween. Typically, as shown in FIG. 11, the first claw portion (claw portion NP2) and the second claw portion (claw portion NP1) are arranged to face each other across the rotation center axis AX6 of the swivel device 130 in the vertical direction (Z-axis direction).

[0160] As described with reference to FIG. 16, this configuration has the effect that it can flexibly correspond to each of a plurality of swivel mounting holes TH having various diameters as compared with a configuration including three or more claw portions. That is, this configuration has the effect that it can flexibly correspond to each of a plurality of swivel mounting holes TH having various diameters.

[0161] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above-described embodiments. Various modifications, substitutions, etc. can be applied to the above-described embodiments without departing from the scope of the present invention. Also, each of the features described with reference to the above embodiments may be appropriately combined as long as there is no technical contradiction.

[0162] For example, the adjustment mechanism AM shown in FIGS. 8 to 13 may be incorporated into the pedestal 120 shown in FIGS. 1 to 6, or may be incorporated into the pedestal 120A shown in FIG. 7. Specifically, the adjustment mechanism AM shown in FIGS. 8 to 13 may be incorporated between the main body member 122 and the base plate 123 of the pedestal 120 shown in FIGS. 1 to 6, or may be incorporated between the main body member 122 and the base plate 123 of the pedestal 120A shown in FIG. 7. Further, the adjustment mechanism AM as shown in FIGS. 8 to 13 may be incorporated between the attachment 110 and the pedestal 120 or the pedestal 120A.
