Note that in FIG. 4B, illustration of the base plate 123 is omitted for clarity.

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

The moving mechanism TM is a mechanism for moving the engaging member constituting the engaging mechanism 121 in the pedestal 120 attached to the thumb-turn mounting hole TH in the radial direction of the thumb-turn mounting hole TH. In this 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 thumb-turn mounting hole TH.

Specifically, the rack and pinion mechanism TM1 is composed of a rack portion RK formed in the central engaging member 121C and a ratchet gear 124. As shown in FIG.

The ratchet gear 124 has a gear portion 124G and a cylindrical portion 124C, as shown in FIG. 5(B). A cylindrical portion 124C of the ratchet gear 124 is fitted into a through hole 122H1 (see FIG. 4A) formed in the body member 122 so as to rotate with respect to the body member 122 about the axis AX4. there is The gear portion 124G is configured to mesh with the rack portion RK of the central engaging member 121C in a state where the cylindrical portion 124C is fitted in the through hole 122H1.

A hole 124R corresponding to the tip shape of a tool for rotating the ratchet gear 124 is formed in the front (X1 side) end face 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 Phillips screwdriver, which is an example of a tool for rotating the ratchet gear 124. As shown in FIG. In addition, the hole 124R may be formed so as to correspond to the tip shape of other tools such as a slotted screwdriver or a hexagonal wrench. Alternatively, the cylindrical portion 124C may be configured to have a knob on its front end face so that the operator can operate it by hand.

The ratchet mechanism LM1 is an example of a movement limiting mechanism LM for limiting the moving direction of the engaging member by the moving mechanism TM to one direction. In the present embodiment, the ratchet mechanism LM1 is configured to allow the upward movement (Z1 direction) of the central engaging member 121C while restricting the downward movement (Z2 direction) of the central engaging member 121C. ing.

Specifically, the ratchet mechanism LM1 is mainly composed of a ratchet gear 124, a ratchet pawl 125, and a ratchet spring 126. The ratchet gear 124 and the ratchet pawl 125 are housed in a recess 122C formed in the rear surface of the body member 122. As shown in FIG.

Ratchet gear 124 is housed in recess 122C so as to be rotatable about axis AX4.

As shown in FIG. 5A, 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 configured to be inserted through a through hole 125H1 formed in the central portion of the ratchet pawl 125 and through a through hole 122H2 (see FIG. 4A) formed in the body member 122. . In this embodiment, ratchet pawl 125 is fixed to pin 125P and configured to rotate with pin 125P about axis AX5. Ratchet pawl 125 and pin 125P may be coupled, for example, by an interference fit. Also, the front end of the pin 125P may be configured to protrude forward from the front surface of the body member 122 so that it can be manually rotated by the operator. Alternatively, the front end face of the pin 125P may be formed with a hole corresponding to the tip shape of a tool for rotating the pin 125P.

A figure 125A represented by a dotted line in FIG. 5A shows the ratchet pawl 125 that rotates around the axis AX5 when the ratchet wheel 124 rotates in the direction indicated by the arrow AR11. A 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.

The ratchet spring 126 is housed in a groove 122T formed in the rear surface of the body member 122, as shown in FIG. 5(A). The ratchet spring 126 has a lower end CT1 fixed to a through hole 125H2 formed in the ratchet pawl 125, and an upper end CT2 fixed to the upper end of the groove 122T. The through hole 125H2 is formed between the through hole 125H1 and the tip portion 125E.

With this configuration, the ratchet spring 126 generates a force that attracts the tip 125E of the ratchet pawl 125 upward (in the Z1 direction), as indicated by the arrow AR10 in FIG. 5(A). The ratchet spring 126 generates torque that rotates the ratchet pawl 125 counterclockwise around the axis AX5 of the pin 125P in a rear view as shown in FIG. 5(A).

When an operator uses a Phillips screwdriver to rotate ratchet gear 124 in the direction indicated by arrow AR11 in FIGS. Pushed by two teeth TE2, it rotates in the direction indicated by arrow AR12 in FIG. 5(A).

At this time, when the engagement between the second tooth TE2 of the ratchet gear 124 and the tip portion 125E of the ratchet pawl 125 is released, the tip portion 125E of the ratchet pawl 125 is pulled upward by the ratchet spring 126, causing the ratchet gear 124 to move. It meshes with the third tooth TE3. When the operator further rotates the ratchet gear 124 in the direction indicated by the arrow AR11, the ratchet pawl 125 rotates further in the direction indicated by the arrow AR11 with the tip 125E pushed by the third tooth TE3 of the ratchet gear 124. The subsequent movements of ratchet wheel 124 and ratchet pawl 125 are the same as those described above.

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

On the other hand, even if the operator tries to rotate the ratchet gear 124 in the direction indicated by the arrow AR14 in FIGS. 5A and 5B using a Phillips screwdriver, 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 ratchet mechanism LM1 disengages the tip 125E of the ratchet pawl 125 from the first tooth TE1 of the ratchet gear 124. can't.

When the operator tries to rotate the ratchet gear 124 in the direction indicated by the arrow AR14 using a Phillips screwdriver, the tip 125E of the ratchet pawl 125 is pushed by 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, the ratchet pawl 125 cannot be rotated clockwise when viewed from the rear. Therefore, the central engaging member 121C cannot move downward (Z2 direction), which is the direction indicated by the arrow AR15.

Thus, the ratchet mechanism LM1 allows the ratchet gear 124 to rotate counterclockwise about the axis AX4 when viewed from the rear as shown in FIG. It is configured so that rotation around it can be restricted. That is, the ratchet mechanism LM1 is configured to allow upward movement of the central engaging member 121C and limit downward movement of the central engaging member 121C.

When the operator wants to move the central engaging member 121C downward, that is, when he wants to rotate the ratchet gear 124 clockwise around the axis AX4, the operator moves the tip 125E of the ratchet pawl 125 by the ratchet mechanism LM1. The meshing of the ratchet gear 124 with the first tooth TE1 can be released.

Specifically, the operator manually rotates the pin 125P configured to rotate together with the ratchet pawl 125 to rotate the ratchet pawl 125 in the direction indicated by the arrow AR12 so that the tip portion 125E and the first tooth TE1 are rotated. It suffices to realize a state in which engagement with is released. Then, the operator rotates the ratchet gear 124 in the direction indicated by the arrow AR14 using a Phillips screwdriver in a state in which the meshing between the tip end portion 125E and the first tooth TE1 is released, thereby rotating the ratchet gear 124 in the direction indicated by the arrow AR15. The central engaging member 121C can be moved downward.

The dotted arrow AR3 in FIG. 4B represents the moving direction of the central engaging member 121C, and the dotted graphic GP5 indicates the central engaging member 121C after it has moved in the Z2 direction (downward). A figure GP6 represented by a dotted line represents the position of the central engaging member 121C after it has been moved in the Z1 direction (upward). The operator can vertically move the central engaging member 121C by rotating the ratchet gear 124 as described above.

Next, with reference to FIG. 6, the engagement mechanism 121 will be described. FIG. 6 is a diagram showing the engagement mechanism 121 in the pedestal 120 fixed to the thumb-turn mounting hole TH. Specifically, FIG. 6A is a front view of the engaging mechanism 121 in the base 120 fixed to the thumb-turn mounting hole TH. FIG. 6(B) is a cross-sectional view of the central engaging member 121C and the door 20 on a plane parallel to the XZ plane including the dashed-dotted line L3 in FIG. 6(A). Although the following description relates to the central engaging member 121C, it is similarly applied to each of the left engaging member 121L and the right engaging member 121R.

The central engaging member 121C, which is a plate-shaped member made of metal such as stainless steel, is configured to have a base portion BS and claw portions CL, as shown in FIG. 6B. 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 of less than 90 degrees. there is

With this configuration, the central engaging member 121C has a rear surface (X2-side surface) of the base portion BS that contacts the interior-side surface 20A of the door 20, and an upper surface (Z1-side surface) of the claw portion CL that is thumb-turn mounted. It is arranged so as to contact the edge CP on the rear side (X2 side) of the inner peripheral surface of the hole TH. Therefore, even if a force to pull out the pedestal 120 forward (in the X1 direction) acts on the pedestal 120, the claw portion CL does not reach the edge CP on the rear side (X2 side) of the inner peripheral surface of the thumb-turn mounting hole TH. Because of the hooking, the pedestal 120 is not pulled away from the door 20.例文帳に追加

In addition, this configuration allows the upper surface of the claw portion CL to come into contact with the rear edge CP of the inner peripheral surface of the thumb-turn mounting hole TH regardless of the length LT of the thumb-turn mounting hole TH. Therefore, this configuration brings about an effect that the engaging 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. Moreover, the claw portion CL may be formed so as to be bent twice or more, or may be formed so as to extend in a curved line.

Next, another configuration example of the pedestal 120 will be described with reference to FIG. FIG. 7 is a diagram showing a pedestal 120A, which is another configuration example of the pedestal 120. As shown in FIG. Specifically, FIG. 7A is an exploded perspective view of the pedestal 120A and corresponds to FIG. 4A. FIG. 7(B) is a rear view of the pedestal 120A and corresponds to FIG. 4(B).

A pedestal 120A shown in FIG. 7 differs from the pedestal 120 shown in FIG. 4 in that it has a feed screw mechanism TM2 as the moving mechanism TM. The pedestal 120 shown in FIG. 4 has a rack and pinion mechanism TM1 as the moving mechanism TM. A base 120A shown in FIG. 7 differs from the base 120 shown in FIG. 4 in that the movement limiting mechanism LM is omitted. The base 120 shown in FIG. 4 has a ratchet mechanism LM1 as the movement limiting mechanism LM. In other respects, the pedestal 120A shown in FIG. 7 and the pedestal 120 shown in FIG. 4 are common. Therefore, the description of the common parts will be omitted, and the different parts will be explained in detail below.

A feed screw mechanism TM<b>2 as a moving mechanism TM is mainly composed of a slider 151 and a screw 152 .

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 unrotatable around the vertical axis. The slider 151 may be made of metal or resin. In the example shown in FIG. 7, the slider 151 has a substantially rectangular parallelepiped shape and is accommodated in a square groove 122S formed in the rear surface (the surface on the X2 side) of the main body member 122. As shown in FIG. The square groove 122S is formed so that the slider 151 can slide vertically and cannot rotate about the vertical axis. Specifically, the rectangular groove 122</b>S is configured such that its length in the vertical direction is significantly longer than the length in the vertical direction of the slider 151 . Further, the rectangular groove 122S is arranged such that the length (width) in the horizontal direction is substantially the same as the length (width) of the slider 151 in the horizontal direction (strictly speaking, the width of the rectangular groove 122S is larger than the width of the slider 151). is slightly larger).

Also, the slider 151 is configured to be fixed to the upper end portion of the central engaging member 121C. In the example shown in FIG. 7, the slider 151 has two protrusions 151T (an upper protrusion 151T1 and a lower protrusion 151T2) that protrude rearward from the rear surface. The two protrusions 151T are configured to be inserted through two through holes 121H (an upper through hole 121H1 and a lower through hole 121H2) formed at the upper end of the central engaging member 121C.

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

Screw 152 is configured to engage slider 151 . In the example shown in FIG. 7, the screw 152 is configured to engage with a female threaded hole 151H formed in the slider 151. As shown in FIG. Specifically, the screw 152 is inserted into the through hole 122H formed in the main body member 122, and the tip extends into the rectangular groove 122S. The screw 152 is screwed into the female screw hole 151H of the slider 151 accommodated in the rectangular groove 122S.

In the example shown in FIG. 7, the screw 152 is a metric screw with a cross-recessed screw head. The operator can move the slider 151 vertically within the square groove 122S by rotating the screw 152 screwed into the female screw hole 151H of the slider 151 with a Phillips screwdriver. This is because the rotation of the slider 151 about the vertical axis is restricted by being accommodated in the rectangular groove 122S.

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

An arrow AR31 represented by a dotted line in FIG. 7(B) represents the moving direction of the central engaging member 121C, and a figure GP31 represented by a dotted line represents the central engaging member 121C after moving in the Z2 direction (downward). A figure GP32 represented by a dotted line represents the position of the central engaging member 121C after it has been moved in the Z1 direction (upward). The operator can vertically move the central engagement member 121C by rotating the screw 152 as described above. Note that in FIG. 7B, illustration of the base plate 123 is omitted for clarity.

With the configuration described above, the base 120A shown in FIG. 7 provides the same effects as the base 120 shown in FIG. Specifically, the pedestal 120A that constitutes the electronic lock mounting structure FS has a unique effect of enabling the electronic lock 100 to be removed from the door 20 without damaging the interior-side surface 20A of the door 20. Bring. This is because there is no need to place a strong double-sided tape between the indoor-side surface 20A of the door 20 and the pedestal 120A.

In addition, the pedestal 120A shown in FIG. 7 has the additional effect of reducing the number of parts compared to the pedestal 120 shown in FIG. Moreover, the base 120A has an additional effect of facilitating vertical movement of the central engaging member 121C compared to the base 120 having the ratchet mechanism LM1 as the movement limiting mechanism LM. When the pedestal 120A is employed, the operator can omit the task of manually operating the ratchet pawl 125 in order to release the movement restriction by the ratchet mechanism LM1. This is because the (central engagement member 121C) can be moved up and down.

As described above, the electronic lock mounting structure FS according to the embodiment of the present invention is arranged between the electronic lock 100 and the door 20 to mount the electronic lock 100 to the door 20, as shown in FIG. is configured to 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.

With this configuration, the electronic lock mounting structure FS provides a unique effect of enabling the electronic lock 100 to be removed from the door 20 without damaging the interior-side surface 20A of the door 20 . This is because there is no need to place a strong double-sided tape between the indoor-side surface 20A of the door 20 and the electronic lock mounting structure FS.

The engaging mechanism 121 includes a plurality of claw portions CL formed to engage with the thumb-turn mounting hole TH, and at least one of the plurality of claw portions to move in the radial direction of the thumb-turn mounting hole TH. a configured transport mechanism TM.

Specifically, as shown in FIGS. 4A and 6B, the engagement mechanism 121 has three claw portions CL (the claw portion CL of the central engagement member 121C and the claw portion CL of the left engagement member 121L). portion CL, and the claw portion CL of the right engaging member 121R) and the claw portion CL of the central engaging member 121C can be moved in the Z-axis direction, which is one of the radial directions of the thumb-turn mounting hole TH. and a moving mechanism TM.

More specifically, the moving mechanism TM may be a rack and pinion mechanism TM1 as shown in FIG. 4(A). In this case, the engagement mechanism 121 may include a ratchet mechanism LM1 (see FIG. 4B) that limits the moving direction of the claw portion CL of the central engagement 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.

These configurations bring about an effect that the mounting strength of the electronic lock unit 10 (pedestal 120) to the door 20 can be increased compared to the case where the electronic lock unit 10 is mounted to the door 20 with double-sided tape. These configurations also have the advantage of allowing the pedestal 120 to be mounted in thumb-turn mounting holes TH having various diameters.

Further, in order to bring about the same effect, the claw portion CL of the left engaging member 121L and the claw portion CL of the right engaging member 121R are made swingable with respect to the base 120 as shown in FIG. 4(B). may be attached.

The three claw portions CL may be arranged at approximately equal intervals along the circumferential direction of the thumb-turn mounting hole TH. Specifically, 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 are substantially circular as shown in FIG. They may be arranged at intervals of approximately 120 degrees along the circumferential direction of the thumb-turn mounting holes TH. The electronic lock unit 10 ( This is because the mounting strength of the pedestal 120) is increased. Therefore, when the engaging mechanism 121 has two claws, the two claws are desirably arranged at intervals of approximately 180 degrees along the circumferential direction of the thumb-turn mounting hole TH. Alternatively, if the engaging mechanism 121 has four claws, the four claws are desirably arranged at intervals of approximately 90 degrees along the circumferential direction of the thumb-turn mounting hole TH.

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 engaging member 121C, the claw portion CL of the left engaging member 121L, and the claw portion CL of the right engaging member 121R) is shown in FIG. , the claw portion CL is bent with respect to the base portion BS so that the angle θ formed between the claw portion CL and the base portion BS is an acute angle, and the rear edge CP of the inner peripheral surface of the thumb-turn mounting hole TH is bent. may be configured to come into contact with the

In this configuration, the claw portion CL is bent perpendicularly to the base portion BS, and compared to the case where the claw portion CL contacts the inner peripheral surface of the thumb-turn mounting hole TH, the electronic lock unit 10 (pedestal 120) for the door 20 is larger than the electronic lock unit 10 (pedestal 120). ) can increase the mounting strength.
