[0010] Preferred embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. In this specification and drawings, components having substantially the same functional configurations are designated by the same reference numerals, and redundant description will be omitted.

[0011] Fig. 1 shows an electronic lock installation jig 1 according to this embodiment. As shown in Figs. 2 and 3, the electronic lock installation jig 1 is used to fix an electronic lock L that rotates a knob T of a thumb turn S to a door D.

[0012] 2 and 3, the electronic lock mounting jig 1 is clamped between the door surface DS and the thumb turn base SD. The electronic lock mounting jig 1 can be mounted on the door by simply removing the thumb turn including the thumb turn base SD from the door, inserting the cylindrical part of the thumb turn into the through hole 11a of the electronic lock mounting jig 1, and then reinserting the thumb turn into the door hole.

[0013] 1 and 4, the electronic lock mounting jig 1 comprises a base plate portion 11 having a through hole 11a for passing a thumb turn device therethrough, and a pair of side plate portions 12a, 12b that rise from the base plate portion 11 and sandwich the electronic lock L from the outside. The pair of side plate portions 12a, 12b are arranged symmetrically with respect to the base plate portion 11, but this is not a limitation as long as they correspond to the positions of the screw holes in the electronic lock. Furthermore, although the electronic lock mounting jig 1 in this example is symmetrical, it is not limited to this and does not have to be completely symmetrical.

[0014] 2 and 3, the electronic lock mounting jig 1 is attached to the door surface facing upward so that the electronic lock L is placed above the thumb turn base SD, but this is not limited to this. For example, as shown in Fig. 8, the electronic lock mounting jig 1 may be attached sideways so that the electronic lock L is placed next to the thumb turn base SD (left or right side), or the electronic lock mounting jig 1 may be attached facing downward so that the electronic lock L is placed below the thumb turn base SD.

[0015] The electronic lock mounting jig 1 of this embodiment has a simple configuration and can prevent the electronic lock from falling off. Specifically, the electronic lock mounting jig 1 is clamped and fixed between the door surface DS and the thumbturn base SD, and the electronic lock L is fixed to the electronic lock mounting jig 1 with screws 15. This structure makes the electronic lock L less likely to fall off than when it is attached to the door surface only with adhesive tape. Furthermore, the electronic lock mounting jig 1 has a simple shape as shown in FIG. 1 and can be manufactured using only sheet metal pressing and bending processes, making it easy to manufacture. Furthermore, installation is easy; simply insert the tubular portion of the thumbturn device through the through-hole 11a of the electronic lock mounting jig 1 to secure the thumbturn device to the door, and then sandwich the electronic lock between the pair of side plates 12a, 12b and screw it in place from the outside. The shape and size of the through-hole 11a can be modified as needed, as long as it can accommodate the tubular portion of the thumbturn device. The through-hole 11a may be circular, oval, rectangular, or may be U-shaped (cutout shaped) that opens sideways. In this case, the thumb turn can be attached by inserting the electronic lock attachment jig 1 from the side while slightly lifting it from the door surface without having to completely pull it out of the door surface.

[0016] In this embodiment, a pair of side plate portions 12a, 12b are each formed with a plurality of screw holes 13 for fixing the electronic lock L to the side plate portions 12a, 12b. The screw holes 13 are formed so that the mounting position of the electronic lock L can be adjusted in the depth direction perpendicular to the door surface DS. As shown in FIG. 4, the plurality of screw holes 13 are arranged in the depth direction. In this example, eight screw holes 13 are formed in the depth direction, but the number may be less than eight or more than eight.

[0017] In this example, two rows of screw holes are arranged in the depth direction, one above the other, spaced apart, for a total of 16 screw holes 13. The screw holes 13 may be arranged in three or more rows, or just one row. In this example, screw holes are formed in two locations, one above and one below, on both sides of the electronic lock L, and as shown in Figures 2 and 3, each side plate portion 12a, 12b is connected to the electronic lock L with screws at two locations, one above and one below (i.e., four locations in total, one on each side). The positions and number of screws can be changed as needed depending on the positions and number of the screw holes in the electronic lock L.

[0018] By changing the positions of the screw holes 13 in the side plate portions 12a and 12b used to secure the electronic lock L in the depth direction, the mounting position of the electronic lock L can be adjusted in the depth direction perpendicular to the door surface DS. Specifically, in the example shown in Figures 2 and 3, the second screw hole 13 from the door side is used, but by using the third or subsequent screw holes 13 for screw fastening, the electronic lock L can be moved farther away from the door surface. On the other hand, by using the screw hole 13 closest to the door, the electronic lock L can be moved closer to the door surface. This configuration makes it possible to adjust the position (depth direction) of the clamping mechanism LP of the electronic lock L relative to the position of the thumbturn knob T. As a result, the clamping mechanism LP can clamp the knob T at an appropriate position depending on the height and shape of the thumbturn knob T, improving the holding accuracy of the knob T, and therefore improving the accuracy of unlocking and locking the electronic lock L (more reliably rotating the thumbturn knob T).

[0019] 1 and 4, the base plate 11 of this example has an annular portion 11b that receives the thumb turn base SD and a flat plate portion 11c extending from the annular portion 11b. A pair of side plates 12a, 12b rise vertically from both sides of the flat plate portion 11c. The annular portion 11b is annular, and the flat plate portion 11c and the side plates 12a, 12b are each approximately rectangular, but are not limited to this and may have any shape.

[0020] As shown in Fig. 1, an annular recess 11d that receives a thumb turn base is formed in the annular portion 11b. Also, as shown in Fig. 4, a protrusion 11e that corresponds to the recess 11d may be formed on the back side.

[0021] As shown in Figures 3 and 4, the electronic lock mounting structure including the electronic lock mounting jig 1 of this example may have adhesive tape 16 arranged on the back surface of the base plate 11 to attach the base plate 11 to the door surface. This allows the adhesive tape 16 to prevent the base plate 11 from rotating around the thumbturn device. In other words, it is possible to reliably prevent the base plate 11 and the electronic lock L from rotating around the tubular portion of the thumbturn device. Even without adhesive tape 16, rotation of the base plate 11 can be prevented by tightly clamping it between the thumbturn base SD and the door surface DS. Furthermore, if adhesive tape 16 is provided, the base plate 11 can be attached and held against the door surface even before the thumbturn device is attached, making it easier to mount the electronic lock mounting jig 1 to the door.

[0022] 3 and 4, a protrusion 11e having a height corresponding to the thickness of the adhesive tape 16 is provided at a position on the rear surface of the base plate 11 where the adhesive tape 16 is not placed (the flat plate portion 11c in this example). By matching the heights of the adhesive tape 16 and the protrusion 11e in this way, it becomes easier to install the base plate 11 and the door surface parallel to each other, and the stability of the fixed electronic lock L can be improved.

[0023] The protrusion 11e in this example is provided on the annular portion 11b of the base plate portion 11 that receives the thumb turn seat SD, but is not limited to this.

[0024] FIG. 5 shows a modified electronic lock mounting jig 100. In the electronic lock mounting jig 100, multiple screw holes 13 are formed so that the mounting position of the electronic lock L can be adjusted in a direction perpendicular to the depth direction. Specifically, multiple screw holes 13a, 13b are formed in a first direction (up and down direction in the figure) perpendicular to the depth direction in FIG. 5, allowing the position of the electronic lock L to be changed. In the example of FIG. 5, an upper screw hole 13a and a lower screw hole 13b are formed, allowing the mounting position of the electronic lock L to be changed in two stages in the first direction, but a structure that allows the position to be changed in three or more stages is also possible. This makes it possible to adjust the position in the first direction (e.g., up and down, left and right positions) of the knob holding portion LT of the electronic lock L relative to the thumb turn knob T.

[0025] 6, 7, and 8 show an electronic lock mounting jig 200 as a further modified example. The electronic lock mounting jig 200 includes spacers 17a and 17b that are arranged between the electronic lock L and at least one of the side plate portions 12a and 12b. The electronic lock mounting jig 200 is configured so that the mounting position of the electronic lock relative to the electronic lock mounting jig 200 can be changed by changing the positions of the spacers 17a and 17b. This makes it possible to adjust the mounting position of the electronic lock according to the position of the rotation axis of the thumb turn knob T.

[0026] In the electronic lock mounting jig 200, the distance between the pair of side plate portions 12a, 12b (the distance in the second direction in FIG. 6) corresponds to the distance obtained by adding the width of the electronic lock L and the thickness of the two spacers 17a, 17b. The number of spacers 17a, 17b is not limited to two, and may be one, or three or more. Like the side plate portions 12a, 12b, the spacers 17a, 17b have screw holes formed therein for inserting screws.

[0027] As shown in FIG. 6, by arranging two spacers 17a and 17b evenly on both sides of the electronic lock L, the electronic lock L is positioned in the center (center in the second direction) of the electronic lock mounting jig 200. Then, as shown in FIG. 7, by arranging two spacers 17a and 17b overlapping on either side of the electronic lock L, the electronic lock L is positioned closer to either side plate portion 12a or 12b (closer to the right side wall 12b in the example of FIG. 7). As a result, even if the thumb turn knob T is eccentric in either direction (downward in the example of FIG. 8) from the center of the thumb turn base, for example, as shown in FIG. 8, the electronic lock L can be positioned in an appropriate position, and the position of the clamping mechanism LP of the electronic lock can be aligned with the position of the thumb turn knob T. Incidentally, by preparing a plurality of spacers with different thicknesses, it is possible to accommodate thumb turn knobs T in various eccentric positions.
