[0008] An embodiment will be described below with reference to the drawings. In each embodiment described below, the direction corresponding to the up-down direction of the surface 20A of the door 20 is defined as the Z-axis direction. The direction corresponding to the left-right direction of the surface 20A of the door 20 is defined as the X-axis direction. The direction perpendicular to the surface 20A of the door 20 (front-rear direction) is defined as the Y-axis direction. The upward direction is defined as the Z-axis positive direction, the rightward direction is defined as the X-axis positive direction, and the Y-axis positive direction is defined as the forward direction.

[0009] [First embodiment] (Schematic configuration of electronic lock mounting structure 10) 1 and 2 are diagrams showing the schematic configuration of an electronic lock mounting structure 10 according to a first embodiment. Fig. 1 shows the electronic lock mounting structure 10 as seen from the front side (positive side of the Y axis). Fig. 2 shows the electronic lock mounting structure 10 as seen from the rear side (negative side of the Y axis).

[0010] The electronic lock mounting structure 10 shown in Figures 1 and 2 is attached to the interior surface 20A (see Figures 5 and 6) of a door 20 equipped with a thumbturn device. As shown in Figures 1 and 2, the electronic lock mounting structure 10 is configured to include an electronic lock 100, a shaft 120, and a base 130. The base 130 is installed on the surface 20A of the door 20 in place of the existing thumbturn device. The shaft 120 is inserted through the base 130. The rear end of the shaft 120 (the end on the negative side of the Y axis) engages with a box lock 30 (see Figure 6) equipped on the door 20. As shown in Figure 1, the electronic lock 100 and the base 130 are separable from each other. This allows the electronic lock 100 to be attached and detached to the base 130 when the base 130 is installed on the surface 20A of the door 20.

[0011] In the electronic lock mounting structure 10, the electronic lock 100 is mounted on the base 130, and the front end (the end on the positive side of the Y axis) of the shaft 120 is connected to the electronic lock 100. As a result, the electronic lock mounting structure 10 can be remotely controlled via wireless communication (e.g., Bluetooth (registered trademark), Wi-Fi (registered trademark), etc.) from various wireless devices (e.g., smartphones, remote controls, etc.) by the electronic lock 100 rotating the shaft 120, thereby operating the box lock 30 and locking and unlocking the door 20.

[0012] 1, the electronic lock mounting structure 10 is provided with two electronic lock fixing screws 141 that penetrate the base 130 in the vertical direction (Z-axis direction). As a result, with the electronic lock 100 attached to the base 130, the electronic lock mounting structure 10 can reliably fix the electronic lock 100 to the base 130 by the two electronic lock fixing screws 141 that penetrate the base 130 from the underside of the base 130.

[0013] (Detailed configuration of electronic lock mounting structure 10) 3 and 4 are exploded perspective views of the electronic lock mounting structure 10 according to the first embodiment. As shown in Fig. 3 and 4, the electronic lock mounting structure 10 includes an electronic lock 100, a shaft 120, a base 130, a relay shaft 142, two electronic lock fixing screws 141, an attachment 150, and a washer 123.

[0014] As shown in FIGS. 3 and 4, the electronic lock 100 has a housing 101, a rotating body 102, a knob 103, an engaging member 104, and four screws 105.

[0015] The housing 101 is a box-shaped resin member that forms the external shape of the electronic lock 100. The housing 101 houses and holds various components of the electronic lock 100. The housing 101 has a side wall surface 101B on the right side (positive side of the X axis), a side wall surface 101C on the left side (negative side of the X axis), and a convexly curved bottom surface 101D on the bottom side (negative side of the Z axis). A cutout portion 101A having a shape cut out in a roughly rectangular parallelepiped shape is formed on the bottom side (negative side of the Z axis) and back side (negative side of the Y axis) of the housing 101. The base 130 is fitted into the cutout portion 101A. The cutout portion 101A has the same shape as the external shape of the base 130. As a result, by fitting the base 130 into the housing 101, the housing 101 can be integrated with the base 130 without creating gaps or steps between the side wall surfaces 101B, 101C of the housing 101 and the side wall surfaces 130A, 130B of the base 130.

[0016] Rotating body 102 is a generally disk-shaped member provided inside the lower part of housing 101 (the part forward (positive side of the Y axis) of notch 101A) on rotation center axis AX. Rotating body 102 can rotate about rotation center axis AX, which extends in a direction perpendicular to surface 20A of door 20 (Y axis direction), by being driven by a motor (not shown) provided inside housing 101. Rotating body 102 is exposed from the rear surface (negative side of the Y axis) of the lower part of housing 101. This allows relay shaft 142 to be attached to rotating body 102 from behind (negative side of the Y axis) the rotating body 102.

[0017] Knob 103 is a generally disk-shaped member that is exposed from the surface of the lower part of housing 101 (the surface on the Y-axis positive side) on rotation center axis AX. Knob 103 is connected to rotating body 102 and can rotate integrally with rotating body 102 around rotation center axis AX. Knob 103 can be rotated by an operator.

[0018] The engaging member 104 is a metal, flat-plate member attached to the back surface of the upper part of the housing 101 (the part above the notch 101A (positive side of the Z axis)). The engaging member 104 is fixed to the back surface of the upper part of the housing 101 with four screws 105 that penetrate the engaging member 104 from the rear (negative direction of the Y axis) of the engaging member 104. The engaging member 104 has a protruding portion 104A that protrudes downward (negative direction of the Z axis) from the center in the left-right direction (negative direction of the X axis) of the lower edge. When the housing 101 is attached to the base 130, the protruding portion 104A is inserted into a gap (recess 136) between the back surface of the base 130 and the surface 20A of the door 20, thereby preventing the housing 101 from easily coming off the base 130. The engaging member 104 has a pair of left and right horizontal portions 104B formed by bending the lower edge portion forward (in the positive direction of the Y axis) at a right angle. Each horizontal portion 104B has a screw hole 104C (see FIG. 6) formed at a position facing the through-hole 134 of the base 130, which penetrates the horizontal portion 104B in the up-down direction.

[0019] The base 130 is a box-shaped member that protrudes from the interior surface 20A of the door 20 and is fixed to the door 20 with screws, and to which the electronic lock 100 is attached. The base 130 has a side wall surface 130A on the right side (positive side of the X axis), a side wall surface 130B on the left side (negative side of the X axis), and a convexly curved lower surface 130C on the lower side (negative side of the Z axis). The outer shape of the base 130 is the same shape as the cutout portion 101A of the housing 101 of the electronic lock 100 (in the example shown in FIG. 1, it is roughly a rectangular parallelepiped). As a result, when the housing 101 of the electronic lock 100 is attached, the base 130 not only holds the housing 101, but can also be integrated with the housing 101 without creating gaps or steps between the side wall surfaces 130A, 130B of the base 130 and the side wall surfaces 101B, 101C of the housing 101.

[0020] The base 130 has a recess 131 that is recessed from the front surface (the surface on the positive side of the Y axis) toward the back surface (the negative side of the Y axis) and that is circular in plan view. The shaft 120 and the relay shaft 142 are rotatably disposed in the recess 131. A first insertion hole 132 for inserting the shaft 120 is formed in the center of the deepest bottom surface of the recess 131 (on the rotation center axis AX). In addition, a pair of second insertion holes 133 are formed around the first insertion hole 132 in the deepest bottom surface of the recess 131, for inserting base fixing screws 135 (see FIG. 5) for fixing the base 130 to the door 20.

[0021] Furthermore, a pair of left and right through-holes 134 are formed in the base 130, penetrating the base 130 in the up-down direction. Two electronic lock fixing screws 141 are inserted into each of the pair of through-holes 134.

[0022] 4, a recess 136 having a constant width is formed on the rear surface of the base 130. The recess 136 extends downward from the center of the upper edge in the left-right direction (X-axis direction) and has a recessed shape. The protrusion 104A of the engagement member 104 engages with the recess 136.

[0023] The shaft 120 is a rod-shaped member made of metal that extends in the Y-axis direction on the rotation center axis AX. The shaft 120 has a flange portion 121 with a partially enlarged diameter near its rear end (the end on the Y-axis negative side). The portion of the shaft 120 rearward of the flange portion 121 is inserted into a first insertion hole 132 of the base 130 and a third insertion hole 151 of the attachment 150 from the front of the deepest bottom surface of the recess 131 of the base 130 (the Y-axis positive direction). A washer 123 is fitted into a groove portion 122 formed near the rear end (the end on the Y-axis negative side) of the shaft 120, thereby preventing the shaft 120 from coming off the base 130 and the attachment 150. As a result, the shaft 120 is incorporated into the attachment 150 and the base 130 so as to be rotatable about the rotation center axis AX. The rear end of the shaft 120 is connected to the locking box 30 of the door 20 (see FIG. 6) by engaging with the locking box 30 of the door 20 inside the door 20. As a result, the shaft 120 can lock and unlock the locking box 30 of the door 20 by rotating around the rotation center axis AX.

[0024] The attachment 150 is a disk-shaped member provided on the rear side (negative side of the Y-axis) of the base 130. The attachment 150 is fitted into an opening 20B that is created in the surface 20A of the door 20 when the existing thumb turn device is removed, and serves to position the base 130 with respect to the opening 20B. Therefore, the attachment 150 has an outer shape (disk-shaped in this embodiment) that corresponds to the shape of the opening 20B. A third insertion hole 151 is formed in the center of the attachment 150 (on the rotation center axis AX) for inserting the shaft 120. In addition, a pair of fourth insertion holes 152 are formed around the third insertion hole 151 in the attachment 150 for inserting base fixing screws 135 (see FIG. 5) for fixing the base 130 to the door 20.

[0025] Each of the two electronic lock fixing screws 141 is inserted from the underside (negative side of the Z axis) of the base 130 into each of the pair of through holes 134 of the base 130. Each of the two electronic lock fixing screws 141 is then screwed into each of the pair of screw holes 104C provided in each of the pair of horizontal portions 104B of the engagement member 104.

[0026] The relay shaft 142 is a rod-shaped member provided between the rotating body 102 and the shaft 120 and extending in the Y-axis direction on the rotation central axis AX. The relay shaft 142 has a pair of arms extending in different radial directions from each other at its front side (positive side of the Y-axis). The relay shaft 142 is fixed to the rotating body 102 by a pair of screws 102A passing through the rotating body 102 and threading into a pair of screw holes 142B formed at the tip of each of the pair of arms. The relay shaft 142 is also fixed to the shaft 120 by fitting the front end of the shaft 120 into a fitting hole 142A formed at its rear side (negative side of the Y-axis). This allows the relay shaft 142 to rotate integrally with the rotating body 102 and the shaft 120 on the rotation central axis AX. In other words, the relay shaft 142 functions as a "connector" that connects the rotating body 102 to the shaft 120. The inner peripheral surface of the fitting hole 142A and the outer peripheral surface of the shaft 120 are partially formed with flat surfaces, which prevents the fitting hole 142A from rotating relative to the shaft 120.

[0027] (Installation procedure for electronic lock installation structure 10) The procedure for installing the electronic lock installation structure 10 according to the first embodiment will be described below with reference to Figures 5 to 7. Figures 5 to 7 are diagrams for explaining the procedure for installing the electronic lock installation structure 10 according to the first embodiment.

[0028] First, the installer passes the rear portion of the shaft 120 beyond the flange portion 121 through the first insertion hole 132 of the base 130 and into the third insertion hole 151 of the attachment 150, and fits the washer 123 into the groove portion 122 of the shaft 120 to assemble the base 130. Then, as shown in FIG. 5, the installer attaches the base 130, with the shaft 120 and attachment 150 assembled, to the surface 20A of the door 20. Specifically, the installer presses the back surface of the base 130 against the surface 20A of the door 20. At this time, the installer fits the attachment 150 into the opening 20B of the door 20 (see FIG. 6), and engages the rear end of the shaft 120 with a component of the box lock 30 (see FIG. 6) inside the door 20. Then, the installer inserts each of the two base fixing screws 135 into each of the pair of second insertion holes 133 of the base 130 and each of the pair of fourth insertion holes 152 of the attachment 150, and screws them into the box lock 30 inside the door 20. Alternatively, as shown in Figure 6, each of the two base fixing screws 135 may be passed through the box lock 30 and screwed into a screw hole 40A formed on the back side of the cylinder lock 40 attached from the exterior surface of the door 20. In this way, the base 130 is fixed to the surface 20A of the door 20 with the screws.

[0029] Next, the installer attaches the electronic lock 100 to the base 130 as shown in Figure 6. Specifically, the installer attaches the engaging member 104 to the back surface of the upper part of the electronic lock 100. The installer also attaches the relay shaft 142 to the rotating body 102 of the electronic lock 100. Then, as shown in Figure 6, the installer fits the front end of the shaft 120 into the fitting hole 142A of the relay shaft 142 while tilting the electronic lock 100 slightly forward, and then releases the forward tilt of the electronic lock 100, and inserts the protruding portion 104A of the engaging member 104 into the recess 136 of the base 130, thereby attaching the electronic lock 100 to the base 130.

[0030] As a result, as shown in Fig. 7, the electronic lock 100 is integrated with the base 130 in a state in which the shaft 120 can be rotated by rotating the relay shaft 142. At this time, as shown in Fig. 7, the side wall surfaces 101B, 101C of the housing 101 of the electronic lock 100 and the side wall surfaces 130A, 130B of the base 130 form a continuous flat surface in the Y-axis direction without creating any gaps or steps. Also, as shown in Fig. 7, the bottom surface 101D of the housing 101 of the electronic lock 100 and the bottom surface 130C of the base 130 form a curved surface that is continuous in the Y-axis direction without creating any gaps or steps.

[0031] 7, the installer inserts each of the two electronic lock fixing screws 141 from the underside of the base 130 into each of the pair of through holes 134 of the base 130 and screws them into each of the pair of screw holes 104C provided in each of the pair of horizontal portions 104B of the engagement member 104. As a result, the electronic lock 100 is fixed to the base 130 with the screws.

[0032] When removing the electronic lock mounting structure 10, the removal worker can easily remove the electronic lock 100 from the base 130 by removing each of the two electronic lock fixing screws 141. Furthermore, the removal worker can easily remove the base 130 from the surface 20A of the door 20 by removing each of the pair of base fixing screws 135. At this time, no traces of double-sided tape or the like remain on the surface 20A of the door 20.

[0033] As described above, the electronic lock mounting structure 10 of the first embodiment is an electronic lock mounting structure 10 for mounting an electronic lock 100 to a thumbturn device installed on a door 20, and comprises a base 130 that is installed on the door 20 in place of the existing thumbturn device and on which the electronic lock 100 is mounted, a shaft 120 that is inserted through the base 130 and connected to the box lock 30 of the door 20, and an intermediate shaft 142 (connecting portion) that connects the rotating body 102 of the electronic lock 100 to the shaft 120.

[0034] As a result, the electronic lock mounting structure 10 of the first embodiment replaces the existing thumb turn device and installs a base 130 on the door 20, making it possible to easily attach and detach the electronic lock 100 to the door 20 and also to securely attach the electronic lock 100 to the door 20.

[0035] Furthermore, in the electronic lock mounting structure 10 according to the first embodiment, the base 130 has a recess 131 that is recessed from the surface on the electronic lock 100 side toward the door 20 side, and the recess 131 has a first insertion hole 132 in the center of the bottom surface through which the shaft 120 is inserted, and has second insertion holes 133 around the first insertion hole 132 on the bottom surface through which base fixing screws 135 for fixing the base 130 to the door 20 are inserted.

[0036] As a result, the electronic lock mounting structure 10 of the first embodiment can arrange the shaft 120 and base fixing screw 135 within the recess 131 so that they are not visible from the outside, thereby improving the appearance of the base 130.

[0037] In addition, the electronic lock mounting structure 10 according to the first embodiment is provided with an engaging member 104 that is attached to the back of the electronic lock 100 and engages with the base 130 when the electronic lock 100 is attached to the base 130.

[0038] As a result, the electronic lock mounting structure 10 of the first embodiment can prevent the electronic lock 100 from easily falling off the base 130 when the electronic lock 100 is attached to the base 130, even before it is fixed with screws.

[0039] Furthermore, in the electronic lock mounting structure 10 of the first embodiment, when the electronic lock 100 is attached to the base 130, there are no gaps or steps between the side wall surfaces 101B, 101C of the electronic lock 100 and the side wall surfaces 130A, 130B of the base 130.

[0040] As a result, when the electronic lock 100 is attached to the base 130, the electronic lock mounting structure 10 of the first embodiment can integrate the electronic lock 100 and the base 130 without creating any visual incongruity.

[0041] Second Embodiment Next, a second embodiment will be described. The following mainly describes the changes made to the electronic lock mounting structure 10-2 according to the second embodiment from the electronic lock mounting structure 10 according to the first embodiment.

[0042] (Schematic configuration of electronic lock mounting structure 10-2) Figures 8 to 11 are diagrams showing the schematic configuration of an electronic lock mounting structure 10-2 according to the second embodiment. Figure 8 shows the electronic lock mounting structure 10 as seen from the front (positive side of the Y axis) with the electronic lock 100 attached to the base 130. Figure 9 shows the electronic lock mounting structure 10 as seen from the rear (negative side of the Y axis) with the electronic lock 100 attached to the base 130.

[0043] 10 shows the electronic lock mounting structure 10 as viewed from the front (positive side of the Y axis) without the electronic lock 100 attached to the base 130. FIG. 11 shows the electronic lock mounting structure 10 as viewed from the rear (negative side of the Y axis) without the electronic lock 100 attached to the base 130.

[0044] As shown in Figures 8 to 11, the electronic lock mounting structure 10-2 of the second embodiment is identical to the electronic lock mounting structure 10 of the first embodiment in that it comprises an electronic lock 100, a shaft 120, a base 130, an intermediate shaft 142, two electronic lock fixing screws 141, and a washer 123, but differs from the electronic lock mounting structure 10 of the first embodiment in that it comprises an attachment 160 instead of attachment 150 on the back side of the base 130.

[0045] (Detailed configuration of electronic lock mounting structure 10-2) 12 and 13 are exploded perspective views of an electronic lock mounting structure 10-2 according to the second embodiment. As shown in Fig. 12 and 13, the attachment 160 is a block-shaped (generally cylindrical) member provided on the rear side (negative side of the Y axis) of the base 130. The shape and fixing method of the attachment 160 differ from those of the attachment 150 of the first embodiment.

[0046] The attachment 160 has an outer shape that allows it to be fitted into a component of the locking box 30 inside the door 20. The attachment 160 has a pair of protrusions 161 that protrude upward (positive direction of the Z axis) and downward (negative direction of the Z axis) from the outer circumferential surface. Each of the pair of protrusions 161 has a through-hole 161A that penetrates the protrusion 161 in the left-right direction (X axis direction). When the attachment 160 is fitted into a component of the locking box 30, pins (not shown) that are assembled from the side of the door and pass through the locking box 30 are inserted into each of the pair of upper and lower through-holes 161A, thereby fixing the attachment 160 to the locking box 30.

[0047] An insertion hole (not shown) is formed in the center of attachment 160 (on rotation center axis AX). A portion of shaft 120 rearward of flange portion 121 is inserted into the insertion hole from the front side (positive side of the Y axis). In this way, attachment 160 rotatably supports shaft 120. With the portion of shaft 120 rearward of flange portion 121 inserted into the insertion hole, washer 123 is fitted into the back side of attachment 160, preventing shaft 120 from falling off attachment 160.

[0048] When the electronic lock 100 is attached to the base 130, the portion of the shaft 120 forward of the flange portion 121 is inserted through the first insertion hole 132 of the base 130, and the front end of the shaft 120 is fitted into the fitting hole 142A of the relay shaft 142 that is fixed with screws to the rotating body 102. As a result, the shaft 120 is connected to the rotating body 102 via the relay shaft 142, and can rotate integrally with the rotating body 102.

[0049] In this way, the electronic lock mounting structure 10, 10-2 according to one embodiment can use, as an "attachment," a shape and fixing method that is specific to the type of box lock 30, depending on the type of box lock 30 of the door 20. In other words, the electronic lock mounting structure 10, 10-2 according to one embodiment is highly versatile, with the components other than the "attachment" being usable for various types of box locks 30.

[0050] Although one embodiment of the present invention has been described in detail above, the present invention is not limited to these embodiments, and various modifications and changes are possible within the scope of the gist of the present invention described in the claims.
