Therefore, the user can rotate the thumb-turn holder 102 by manually rotating the knob 103 to rotate the knob portion 132 engaged with the groove portion 102A of the thumb-turn holder 102 .

Thus, the electronic lock unit 10 according to the first embodiment can easily and firmly attach the electronic lock 100 to the thumb-turn device 130 .

(Gap 10B formed by electronic lock unit 10)
3A to 3C are views of the electronic lock unit 10 according to the first embodiment viewed from the right side. The electronic lock unit 10 according to the first embodiment attaches the electronic lock 100 to the thumb-turn device 130 by engaging the muscle portion 121 of the attachment 120 with the groove portion 131A of the thumb-turn device 130, as described with reference to FIG. In this case, a gap 10B having a predetermined distance is formed between the rear surface 120B of the attachment 120 and the front surface 20A of the door 20. As shown in FIG. Since the attachment 120 is integrated with the electronic lock 100, the rear surface 120B of the attachment 120 corresponds to "the rear surface of the electronic lock".

In particular, the electronic lock unit 10 according to the first embodiment has three grooves 131A (groove 131A1, groove 131A2, and groove 131A3) formed on the side surface of the pedestal 131 of the thumb-turn device 130. By selectively changing the groove portion 131A with which the streak portion 121 is formed, the interval of the gap 10B can be adjusted to any of intervals D1, D2, and D3.

In this case, a gap 10B having the smallest distance D3 is formed between the rear surface 120B of the attachment 120 and the front surface 20A of the door 20. FIG.

At this time, since lock portions 131B1, 131B2, and 131B3 are provided in each groove portion, movement of the electronic lock 100 in the Z-axis direction can be restricted regardless of which groove portion 131A is engaged. In addition, the operation portion 131C has a structure in which the lock portions 131B1, 131B2, and 131B3 can be commonly operated, so that the electronic lock 100 can be thumb-turned by one operation portion 131C even when it is engaged with any of the groove portions 131A. Make it removable from the device 130 .

Further, regarding the height of the knob portion 132 of the thumb-turn device 130 in the Y-axis direction and the depth of the groove portion 102A of the thumb-turn holder 102 in the Y-axis direction, the knob portion 132 and the groove portion 102A are the same regardless of which groove portion 131A is selected. is preset to a dimension that allows sufficient engagement, there is no need to change parts of the electronic lock 100 or the thumb-turn device 130 depending on the gap 10B.

Note that the intervals D1 to D3 are all capable of allowing sufficient ultraviolet light UV to enter between the back surface 120B of the attachment 120 and the front surface 20A of the door 20 compared to the conventional technology, and , the air permeability between the back surface 120B of the attachment 120 and the front surface 20A of the door 20 is set to a value that can sufficiently improve the air permeability.

The electronic lock unit 10 according to the first embodiment forms a gap 10B between the back surface 120B of the attachment 120 and the surface 20A of the door 20, thereby allowing sufficient ultraviolet light UV to enter the gap 10B. be able to. As a result, the electronic lock unit 10 according to the first embodiment can suppress, for example, uneven burning of the surface 20A of the door 20 due to ultraviolet light UV.

Further, in the electronic lock unit 10 according to the first embodiment, the gap 10B is formed between the back surface 120B of the attachment 120 and the front surface 20A of the door 20, thereby sufficiently increasing the air permeability in the gap 10B. be able to. Thereby, the electronic lock unit 10 according to the first embodiment can suppress condensation and corrosion on the rear surface 120B of the attachment 120 and the front surface 20A of the door 20, for example.

Note that in the electronic lock unit 10 according to the first embodiment, the base 131 of the thumb-turn device 130 may have two or less grooves 131A, or may have four or more grooves 131A.

Further, in the electronic lock unit 10 according to the first embodiment, the thumb-turn device 130 has one groove portion 131A, and the attachment 120 of the electronic lock unit 10 has a plurality of muscle portions 121 formed in the direction perpendicular to the Y axis. The gap 10B may be adjusted by selecting the muscle 121 of the position.

Further, in the electronic lock unit 10 according to the first embodiment, grooves may be provided on the attachment 120 side, and streaks may be provided on the pedestal 131 side of the thumb-turn device 130 .

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

Further, in the electronic lock unit 10 according to the first embodiment, the position of the muscle portion 121 on the side surface of the attachment 120 is determined so that the position of the muscle portion 121 of the attachment 120 can be determined from the appearance of the electronic lock unit 10. By providing a mark corresponding to , it is possible to make the work easier as a guideline for mounting.

The case of corrosion is, for example, when the surfaces of the four screws 122 exposed on the back surface 120B side of the attachment 120 come into contact with the surface 20A of the metal door 20 and are ionized to corrode (electrolytic corrosion). ), or if the resin attachment 220 has a different property than the resin film or coating used to decorate the surface 20A of the door 20, a chemical reaction may occur and the resin attachment 220 may melt. Moreover, it is conceivable that the four screws 122 are oxidized and rusted due to dew condensation on the surface 20A of the door 20, and the surface 20A of the door 20 is corroded. Therefore, since the electronic lock unit 10 according to the first embodiment can form the gap 10B between the back surface 120B of the attachment 120 and the front surface 20A of the door 20, it is particularly necessary to provide a structure that prevents corrosion. Therefore, corrosion occurring on the surface 20A of the door 20 can be reliably prevented.

As a result, as shown in FIG. 6C, the electronic lock 100 and the attachment 220 are fixed to the plate 233 of the thumb-turn device 230 with the pedestal 231 inserted through the opening 220A. Installation is finished.

At this time, each of the four engaging claws 233A of the pedestal 231 of the thumb-turn device 230 engages with a groove-shaped portion 220Ca formed on the inner peripheral edge of the opening 220A of the attachment 220, thereby Movement of the lock 100 in the front-rear direction (Y-axis direction) is restricted, so that the electronic lock 100 is prevented from easily falling out of the thumb-turn device 230 .

Further, the groove-shaped portion 220Ca formed on the inner peripheral edge portion of the opening portion 220A of the attachment 220 is formed as an inclined surface whose width gradually decreases, and each of the four engaging claws 233A of the pedestal 231 of the thumb-turn device 230 and the opening of the attachment 220 are aligned. Unnecessary rotation of the electronic lock 100 with respect to the thumb-turn device 230 is suppressed by the engagement frictional force with the groove-shaped portion 220Ca formed on the inner peripheral edge portion of the portion 220A. It may be fixed so that it cannot be easily rotated to an angle of rotation that is removable from the thumb-turn device 230 .

However, by rotating the electronic lock 100 counterclockwise about the rotation center axis AX2 again by 45 degrees, the four engaging claws 233A are engaged with the groove-shaped portion 220Ca formed on the inner peripheral edge of the opening 220A. are disengaged, thereby allowing electronic lock 100 to be removed from thumb-turn device 230 .

When the electronic lock 100 is attached to the thumb-turn device 230, the knob portion 232 enters and engages with the groove portion 102A of the thumb-turn holder 102 of the electronic lock 100. Further, the rotation center axis AX2, which is the rotation center of the thumb-turn holder 102, and the rotation center axis AX1, which is the rotation center of the knob portion 232, coincide with each other. As a result, the electronic lock 100 rotates the thumb-turn holder 102 by remote control from various wireless devices, thereby rotating the knob portion 232 to change the state in which the door 20 is locked and the state in which the door 20 is unlocked. It is possible to switch to

Note that, as shown in FIG. 6, the electronic lock 100 has a knob 103 exposed from the surface 101B of the housing 101. As shown in FIG. Knob 103 is rotatable together with thumb-turn holder 102 . Therefore, the user can rotate the thumb-turn holder 102 by manually rotating the knob 103 to rotate the knob portion 232 engaged with the groove portion 102A of the thumb-turn holder 102 .
