Description

[Technical Field]

[0001] The present invention relates to an operation unit for performing unlocking and locking operations of an electric lock. [Background technology]

[0002] Various types of electric locks have been proposed in the past. These electric locks not only advance and retract the deadbolt with a power unit driven by electricity, but also incorporate various other innovations. For example, some electric locks are equipped with an operating unit equipped with a manual operating member that advances and retracts the deadbolt of the electric lock so that it can be unlocked and locked even when the electricity is cut off. The most common operating member is a rotary type called a thumbturn, as disclosed in Patent Document 1. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2017-150237 Summary of the Invention [Problem to be solved by the invention]

[0004] However, a thumb turn requires two actions: pinching it with your fingers and then turning it, making it very difficult to unlock and lock the door when your hands are full. Therefore, the related invention of the present invention has the object of providing an electric lock that can be switched between locked and unlocked states using an electric mechanism, and an operation unit for the electric lock that can be switched between locked and unlocked states with a single manual operation. An object of the present invention is to provide an operation unit that can be attached to an existing electric lock. [Means for solving the problem]

[0005] An aspect of the present invention to solve the above problem is an operation unit for an electric lock attached to a wing-type door, which has a power transmission mechanism that transmits power to the deadbolt side of the electric lock, and an operation unit that is manually operated, wherein the operation unit is engaged with the power transmission mechanism and is capable of linear reciprocating movement, and is capable of switching between the unlocked and locked states of the electric lock.

[0006] According to this aspect, the operating unit has a power transmission mechanism that transmits power to the deadbolt side of the electric lock and a manually operated operating part, and the operating part is engaged with the power transmission mechanism and is capable of reciprocating linear movement. In other words, when the operating part is pressed or pulled, it moves linearly. Therefore, the electric lock can be switched between the unlocked and locked states by pressing or pulling the operating part. Therefore, the operating unit of this aspect does not need to be held with fingers, and the electric lock can be switched between the unlocked and locked states simply by pressing the operating part to move it in the pressing direction or pulling it to move it in the pulling direction. In other words, the electric lock can be locked and unlocked simply by moving the operating part linearly. Specifically, even if you are carrying luggage in your hand and are unable to grasp the operating part (cannot use your fingers), you can unlock and lock the electric lock by pressing or pulling the sliding operating part.

[0007] It is preferable that the device has a housing that houses the power transmission mechanism, the operating unit is capable of reciprocating along the housing, and the operating unit is detachable from the housing.

[0008] According to this configuration, the operating unit can be attached to the housing after adjusting the engagement position between the operating unit and the power transmission mechanism. Therefore, the operating unit can be adapted to left-opening electric locks that are designed to be attached to the left side of the door and right-opening electric locks that are designed to be attached to the right side of the door. In other words, the operating unit can be customized to accommodate left-opening and right-opening wing-type doors. Furthermore, when the operating unit is moved back and forth between two predetermined positions relative to the housing, the electric lock can be set to a locked state or an unlocked state when in one position, and the electric lock can be set to a locked state or an unlocked state when in the corresponding other position.

[0009] The operating unit has a main body member and a decorative member, and when the main body member and the decorative member are integrated, the operating unit cannot be removed from the housing; when the operating unit is in a specific position relative to the housing, the decorative member can be removed from the main body member; and when the main body member from which the decorative member has been removed is in a different position different from the specific position, the operating unit can be removed from the housing.

[0010] This configuration prevents the operating unit from accidentally coming off the housing or from being carelessly detached from the operating unit and the power transmission mechanism. Furthermore, the operating unit can be detached from the housing and the power transmission mechanism as needed.

[0011] The operation unit is located on the indoor side of the door, and an outdoor operation unit that switches the electric lock between unlocked and locked states is located on the outdoor side of the door, and it is preferable that at least one of the two operation units is provided with multiple bolt engaging members with female threads, and the spacing between the bolt engaging members can be changed. This electric lock operation unit is attached to a door equipped with an electric lock, and an operation unit that switches the electric lock between an unlocked state and a locked state is located on both the indoor and outdoor sides of the door, and at least one of the indoor operation unit and the outdoor operation unit is provided with multiple bolt engaging members with female threads, and the spacing between the bolt engaging members can be changed.

[0012] With this configuration, the spacing of the bolt insertion holes in an existing electric lock can be adjusted by changing the spacing of the bolt engaging members. In other words, the operation unit and outdoor operation unit according to this embodiment can be easily attached to an existing electric lock. One aspect of the present invention is an electric lock operation unit that is attached to a door equipped with an electric lock, and an operation unit that switches the electric lock between an unlocked state and a locked state is located on the inside and outside of the door, and at least one of the inside operation unit and the outside operation unit is provided with a plurality of bolt engaging members with female threads, and the spacing between the bolt engaging members can be changed. In the above-described aspect, it is desirable that the other of the indoor operation unit and the outdoor operation unit has a long bolt insertion hole, and that a bolt is inserted between the bolt insertion hole and the bolt engaging member. In each of the above aspects, it is desirable that the elongated bolt insertion hole extends in an oblique direction. In each of the above-described aspects, it is desirable that a pair of the elongated bolt insertion holes be provided, and that the pair of bolt insertion holes be provided so as to form a "V" shape. In each of the above-mentioned aspects, it is desirable that the bolt engaging member has a linear back support portion that supports the back portion thereof, the back support portion being located at a position offset from the axis of the female thread of the bolt engaging member, the indoor operation unit and the outdoor operation unit being fastened together with a bolt, and the bolt being able to either thread into the female thread of the bolt engaging member and stop midway through the female thread, or to pass through the female thread. In each of the above-mentioned aspects, it is desirable to have a power transmission mechanism that transmits power to the deadbolt side of the electric lock and an operating unit that is manually operated, and the operating unit is engaged with the power transmission mechanism and is capable of linear reciprocating movement, and is capable of switching between the unlocked state and the locked state of the electric lock. [Effects of the Invention]

[0013] The operation unit for an electric lock of the present invention allows for easy manual operation of locking and unlocking the electric lock. [Brief explanation of the drawings]

[Figure 32] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0015] The following description will be made with reference to the drawings. In the following description, the up and down directions are based on the up and down directions in the posture shown in FIG. As shown in Figure 1, an electric lock 1 is attached inside a door 5. The door 5 is a wing-type door that rotates around a hinge (not shown). The electric lock 1 is equipped with a deadbolt 4 and a power mechanism (not shown) that moves the deadbolt 4 forward and backward. A through-hole (not shown) is provided in the door 5, and this through-hole communicates with the electric lock 1.

[0016] As shown in Figure 1, an indoor unit 2 is attached to the indoor side of the door 5, and an outdoor unit 3 (outdoor operation unit) is attached to the outdoor side of the door 5. The indoor unit 2 and the outdoor unit 3 are fastened to each other with bolts (not shown) across the door 5. Both the indoor unit 2 and the outdoor unit 3 have the function of switching the electric lock 1 between an unlocked state and a locked state.

[0017] The outdoor unit 3 includes an input unit (e.g., a numeric keypad) through which the person entering the room enters a PIN, a receiving unit that communicates wirelessly (via Bluetooth or infrared communication) with an authentication device carried by the person entering the room, and a control unit that determines whether the input information entered from the input unit and the authentication signal received by the receiving unit are valid, and if they are determined to be valid, activates the electric lock 1. That is, in response to a command from the control unit, the electric lock 1 activates a power mechanism unit (not shown) and moves the deadbolt 4 forward or backward.

[0018] Next, the indoor unit 2, which is the operation unit according to this embodiment, will be described. As shown in FIGS. 2 to 6, the indoor unit 2 has a housing 6, a slide operation member 7 (operation section), and a power transmission mechanism section 8.

[0019] The housing 6 forms the outer shell of the indoor unit 2 and is a member that houses the power transmission mechanism 8 described below. The housing 6 also is a member that slidably engages the slide operation member 7. As shown in FIGS. 3 and 4, the housing 6 has a fixed portion 6a that is fixed to the door 5 (FIG. 1) and a lid portion 6b that is detachably integrated with the fixed portion 6a. The housing 6 has a substantially rectangular parallelepiped shape, and inside thereof, there are formed an area that houses a battery 9 (power source) and an area that houses the power transmission mechanism 8. The battery 9 is covered by a battery case 6c. The battery case 6c may be fixed to both the fixed portion 6a and the lid portion 6b, or to only one of them. In this embodiment, an area that houses the power transmission mechanism 8 is provided below the area that houses the battery 9.

[0020] The cover portion 6b is provided with a placement portion 10 for placing the slide operation member 7. As shown in FIG. 5, the placement portion 10 is a generally U-shaped recess provided on the lower side of the cover portion 6b and extending in the vertical direction. Protrusions 11 extending vertically are provided at opposing positions on the generally U-shaped placement portion 10. The protrusions 11 extend from near the bottom end of the placement portion 10 to a height position approximately near the center of the placement portion 10. The protrusions 11 partially narrow the width of the placement portion 10. In other words, the width of the placement portion 10 is wider on the upper side and narrower on the lower side.

[0021] The lower end portions of the lid portion 6b on both sides of the placement portion 10 constitute protrusions 12 that protrude in the direction opposite to the fixed portion 6a. A curved surface 12a is formed on the upper portion of the protrusions 12. The curved surface 12a is a downwardly convex curved surface. Due to the protrusions 12, the thickness of the lid portion 6b in the protruding direction of the protrusions 12 increases as it goes downward.

[0022] A slide operation member 7 (operation unit) is disposed in the arrangement unit 10. As shown in FIGS. 7(a) and 7(b), the slide operation member 7 has an outer shape that fits perfectly into the U-shaped arrangement unit 10. As shown in FIGS. 8(a) and 8(b), the slide operation member 7 has a main body member 14 and a decorative member 15.

[0023] The main body member 14 has a front portion 14a and an upstanding wall portion 14b. The front portion 14a is a generally rectangular, flat plate-like portion when viewed from the front, and constitutes the front wall of the main body member 14. A curved surface 13 is continuous with one longitudinal side of the front portion 14a. An upright wall portion 14b is arranged around the edge of the front portion 14a. The long side portions of the front portion 14a are continuous with the upright wall portion 14b, and the short side portions are spaced apart from the upright wall portion 14b.

[0024] The upright wall portion 14b is disposed around the edge of the front portion 14a, intersects (is perpendicular to) the front portion 14a, and constitutes a side wall of the main body member 14. That is, a space 32 is formed by the front portion 14a and the upright wall portion 14b.

[0025] Mounting portions 16a and 16b are provided at longitudinally intermediate positions on the outer side of the upright wall portion 14b. The mounting portions 16a and 16b are provided at positions facing each other on the upright wall portion 14b. The mounting portions 16a and 16b are recessed portions of the upright wall portion 14b. Screw holes 19a and 19b are provided in the mounting portions 16a and 16b, respectively.

[0026] An adapter member 17 is attached to the attachment portions 16a and 16b. The adapter member 17 is a plate-shaped member having a base side and a tip side. The base side is provided with through-holes (not shown) through which screws 20a and 20b for fixing to the attachment portion 16a or 16b are passed. Also, a notch 17a is provided on the tip side. That is, the tip side of the adapter member 17 has a recessed central portion due to the notch 17a, and the outer shape of the tip side is roughly U-shaped.

[0027] The adapter member 17 is fixed to one of the mounting portions 16a, 16b with screws. That is, screws 20a, 20b passing through the adapter member 17 are threaded into screw holes 19a, 19b in the mounting portion 16a (or the mounting portion 16b), thereby fixing the adapter member 17 to the mounting portion 16a (or the mounting portion 16b). Therefore, the adapter member 17 can be attached to and detached from the mounting portion 16a (or the mounting portion 16b). Abutment portions 26 are provided on the upright wall portion 14b adjacent to the mounting portions 16a and 16b.

[0028] The opposite short sides in the longitudinal direction of the standing wall portion 14b are spaced apart from the front surface portion 14a, so that gaps 21a and 21b are formed between the opposite short sides in the longitudinal direction of the standing wall portion 14b and the front surface portion 14a.

[0029] One short side of the standing wall portion 14b constitutes an engaging portion 31. The engaging portion 31 is a portion that engages with a member on the power transmission mechanism 8 side, which will be described later. A locking portion 22 (FIG. 10(a)) is provided at the end of the engaging portion 31 on the front surface 14a side. The locking portion 22 is a portion that protrudes from the short side (engaging portion 31) of the standing wall portion 14b toward the front surface 14a (toward the gap 21a). The other short side of the pair of opposing long sides of the standing wall portion 14b constitutes a wide portion 23 that extends along the curved surface 13 of the front surface 14a. Both wide portions 23 are connected by a flat bottom wall 14c.

[0030] A reinforcing piece 14d is provided in the area surrounded by both wide portions 23 and bottom wall 14c. Reinforcing piece 14d is a generally plate-shaped portion that extends in the opposite direction to the direction in which curved surface 13 extends, with its base fixed to bottom wall 14c and both sides fixed to both wide portions 23. The tip is open and has a step 18 formed at it.

[0031] 10(a), the surface of the reinforcing piece 14d on the front portion 14a side forms an inclined surface 30. The inclined surface 30 is inclined so that the closer to the step portion 18 the surface is, the closer it is to the front portion 14a.

[0032] The step portion 18 has an engagement surface 18a and an upright surface 18b. The engagement surface 18a is a surface parallel or substantially parallel to the front surface 14a. The upright surface 18b is a wall surface that intersects (is perpendicular to) the engagement surface 18a.

[0033] 8(a), 8(b), and 10(a), a void 21b is formed in the area surrounded by the reinforcing piece 14d, the curved surface 13 of the front portion 14a, and both wide portions 23. The void 21b is a hole that penetrates the main body member 14 in the normal direction of the front portion 14a.

[0034] On the other hand, as shown in FIG. 8(a), the decorative member 15 has a front portion 15a and a side portion 15b. The front portion 15a and the side portion 15b are integrated. The front portion 15a is a substantially rectangular plate-like portion and forms the front wall of the decorative member 15. One longitudinal side of the front portion 15a is curved to form a curved surface 24. A protruding wall 25 is further continuous with the curved surface 24. The protruding wall 25 is parallel to the flat portion of the front portion 15a and is curved and continuous with the curved surface 24. The curved surface 24 is a curved surface similar to the curved surface 12a of the lid portion 6b.

[0035] A protruding engagement portion 28 is provided at the end of the front surface 15a opposite to the curved surface 24. The protruding engagement portion 28 is cantilevered, with its base side fixed to the front surface 15a and a protruding ridge 28a on its free end side. As shown in Figures 8(a) and 10(a), the protruding ridge 28a is parallel to the front surface 15a and protrudes outward.

[0036] Side portions 15b are provided on both edges of the curved surface 24 and the protruding wall 25. The side portions 15b extend along the curved surface 24 from the front portion 15a toward the protruding wall 25. Holding portions 27 are provided on both side portions 15b. The holding portions 27 have engagement surfaces 27a that are parallel to the front portion 15a. As shown in FIG. 8(a), the engagement surfaces 27a are provided on the rear side of the front portion 15a by the thickness of the front portion 15a.

[0037] The protruding wall 25 and the side surface 15b are continuous via the bottom wall 15c. The bottom wall 15c intersects with the protruding wall 25 and the side surface 15b. As shown in FIGS. 8(b) and 10(b), an elastic engagement portion 29 is provided in the area surrounded by the protruding wall 25, both side surface portions 15b, and the bottom wall 15c. The elastic engagement portion 29 is plate-shaped, and one end is fixed to the protruding wall 25 in a cantilevered manner. The other end of the elastic engagement portion 29 is a free end and is provided with a turned portion 29a. The turned portion 29a forms a step that projects toward the bottom wall 15c. The surface of the turned portion 29a facing the bottom wall 15c forms an inclined surface 29b. The inclined surface 29b is inclined so that the portion closer to the step of the turned portion 29a projects toward the bottom wall 15c. The elastic engagement portion 29 can swing slightly around its base, allowing the position of the turned portion 29a to be changed.

[0038] Next, how to attach and detach the main body member 14 and the decorative member 15 will be described. The protruding engagement portion 28 of the decorative member 15 is inserted into the gap 21a of the main body member 14 shown in Figure 10(a), and as shown in Figure 10(b), the protruding strip 28a is engaged with the locking portion 22 of the main body member 14. When viewed from the outside, this state appears as shown in Figures 9(a) and 9(b).

[0039] The decorative member 15 is swung relative to the main body member 14 around the protruding engagement portion 28, causing the elastic engagement portion 29 to enter the gap 21b of the main body member 14. The inclined surface 29b at the tip of the elastic engagement portion 29 on the decorative member 15 side abuts against the inclined surface 30 of the reinforcing piece 14d on the main body member 14 side, and the inclined surface 29b is pressed against the inclined surface 30. As the elastic engagement portion 29 enters further into the gap 21b, the elastic engagement portion 29 elastically deforms, and the turned-up portion 29a is displaced toward the front portion 15a. When the inclined surface 29b passes the inclined surface 30, the pressing force that elastically deformed the elastic engagement portion 29 is no longer applied, the elastic engagement portion 29 returns to its original straight position, and the turned-up portion 29a engages with the engagement surface 18a ( FIG. 10(b) ). The engagement between the turned-up portion 29a and the engagement surface 18a will not be released unless the elastic engagement portion 29 is elastically deformed.

[0040] At this time, as shown in Figures 7(a) and 7(b), the front portion 15a, curved surface 24, both side portions 15b, protruding walls 25, and bottom wall 15c of the decorative member 15 fit onto the front portion 14a, curved surface 13, wide portions 23 of both upright wall portions 14b, gap 21b, and bottom wall 14c of the main body member 14. In addition, both holding portions 27 on the decorative member 15 abut and fit onto both abutting portions 26 on the main body member 14. This prevents the decorative member 15 from shifting laterally relative to the main body member 14. Furthermore, as shown in Figure 7(a), the front portion 14a of the main body member 14 and the engagement surfaces 27a of the holding portions 27 on the decorative member 15 are close to each other, and are arranged on approximately the same plane.

[0041] A step is formed between the front surface 14a (the portion not covered by the front surface 15a) and the engagement surface 27a and the front surface 15a. Furthermore, the attachment portions 16a and 16b of the main body member 14 are exposed and not covered by the decorative member 15. In other words, the adapter member 17 can be attached to and detached from the main body member 14 regardless of whether the decorative member 15 is present or not.

[0042] Next, a procedure for removing the decorative member 15 from the main body member 14 will be described.

[0043] 10(b) is inserted between the upright surface 18b (upright wall) of the step portion 18 of the reinforcing piece 14d and the inclined surface 29b of the elastic engagement portion 29, and the inclined surface 29b is pressed to elastically deform the elastic engagement portion 29 and disengage the turned-back portion 29a from the engagement surface 18a. At this time, the inclined surface 29b is moved toward the protruding wall 25, and the inclined surface 29b is engaged with the inclined surface 30. As a result, the inclined surface 29b slides along the inclined surface 30 due to the elastic force of the elastic engagement portion 29, and the elastic engagement portion 29 retreats from the gap 21b. In other words, one side of the decorative member 15 is disengaged from the main body member 14.

[0044] As a result, the decorative member 15 can move longitudinally relative to the main body member 14, disengaging the protrusion 28a of the decorative member 15 from the locking portion 22 of the main body member 14, and removing the decorative member 15 from the main body member 14.

[0045] The power transmission mechanism 8 will now be described. The power transmission mechanism 8 is a member that has the function of transmitting power to the deadbolt 4 (Fig. 1) of the electric lock 1. As shown in Figs. 3 to 6, the power transmission mechanism 8 has a hub 35, a manual-side intervening member 36, an electric-side intervening member 37, a motor 38, an intermediate gear 39, a clutch mechanism 42, a lid-side support member 43, a fixed-part-side support member 44, etc.

[0046] The hub 35 is a rotating body, and a shaft portion 45 is attached to the center of rotation. One end of the shaft portion 45 is supported by the cover-side support member 43, and the other end is supported by the fixed-portion-side support member 44. In other words, the shaft portion 45 is supported at both ends. As shown in Figures 5, 6, 15, and 19, the outer shape of the hub 35 is approximately circular, and protrusions 46 that protrude radially outward are provided at four locations on the outer periphery. Two of the four protrusions 46 form a pair, and an engagement recess 47 is formed between each pair of protrusions 46. The engagement recess 47 is an elongated groove. Furthermore, the cover-side support member 43 has an abutment surface 43a that abuts the slide operation member 7, as shown in Figure 5.

[0047] As shown in Figures 20(a), 20(b), and 21, the manual-side intervening member 36 has a short, generally rectangular parallelepiped shape and includes a hub-side engaging portion 48a and a slide operation member-side engaging portion 48b. The hub-side engaging portion 48a and the slide operation member-side engaging portion 48b are positioned opposite each other and protrude in opposite directions. The hub-side engaging portion 48a has a cylindrical shape, and the diameter of the cylinder is large enough to fit exactly into the engaging recess 47 of the hub 35.

[0048] The slide operation member-side engaging portion 48b is a plate-shaped portion, and its height dimension is such that it fits exactly into the notch 17a of the adapter member 17 of the slide operation member 7. The hub 35 and the slide operation member 7 (adapter member 17) are connected via the manual-side intervening member 36 so that power can be transmitted. At that time, the hub-side engaging portion 48a of the manual-side intervening member 36 swings within the engaging recess 47 of the hub 35.

[0049] The other engaging recess 47 of the hub 35 engages with the electric motor side intervening member 37 . The electric-side intervening member 37 is a member having a relatively long rectangular parallelepiped shape. As shown in Fig. 6, a hub-side engaging portion 49a that engages with an engaging recess 47 of the hub 35 is provided near the lower end of the electric-side intervening member 37. In addition, a clutch-mechanism-side engaging portion 49b that engages with a clutch mechanism 42 (described below) is provided at the top of the electric-side intervening member 37. The hub-side engaging portion 49a and the clutch-mechanism-side engaging portion 49b are provided on the same side of the rectangular parallelepiped-shaped electric-side intervening member 37.

[0050] The hub-side engaging portion 49a has a cylindrical shape, and the diameter of the cylinder is large enough to fit exactly into the engaging recess 47 of the hub 35. The clutch mechanism-side engaging portion 49b has an annular structure with a horizontally long hole. A cylindrical engaging protrusion 60 of the disk member 41 of the clutch mechanism 42, which will be described later, is disposed in the clutch mechanism-side engaging portion 49b. The diameter of the clutch mechanism-side engaging portion 49b in the minor axis direction is large enough to fit the cylindrical engaging protrusion 60.

[0051] When viewed from the hub 35 as a reference, as shown in FIGS. 15 and 19, the manual-side intervening member 36 engages with one of the engaging recesses 47, and the electric-side intervening member 37 engages with the other engaging recess 47.

[0052] As shown in Figures 5 and 6, the electric lock 1 (Figure 1) has a motor 38 and an intermediate gear 39 as a drive source. A gently inclined helical gear 38b is provided on the output shaft 38a of the motor 38. The intermediate gear 39 also has a motor-side gear portion 39a with a relatively large diameter and a clutch-side gear portion 39b with a relatively small diameter. The motor-side gear portion 39a and the clutch-side gear portion 39b are concentric. As shown in Figures 15 and 19, the motor-side gear portion 39a is engaged with the helical gear 38b of the motor 38. The clutch-side gear portion 39b is engaged with a large-diameter gear 40 of the clutch mechanism portion 42, which will be described later.

[0053] The rotation shaft of the intermediate gear 39 is fixed to the cover-side support member 43 and the fixed-portion-side support member 44. That is, the rotation shaft of the intermediate gear 39 is supported at both ends. Also, as shown in Figures 3 and 4, the motor 38 is supported by the fixed-portion-side support member 44.

[0054] The lid-side support member 43 and the fixed-part support member 44 are integrated within the housing 6 and support the various components of the power transmission mechanism 8. A protruding engagement portion 51 is provided on the abutment surface 43a of the lid-side support member 43 that faces the lid part 6b. The protruding engagement portion 51 is a member that has a size and shape that can be housed in the space 32 of the main body member 14 of the slide operation member 7.

[0055] The lid-side support member 43 is integrated with the housing 6, and the position of the protruding engagement portion 51 within the housing 6 is fixed. A placement portion 10 for the lid portion 6b is provided on the front side of the protruding engagement portion 51. As shown in Figure 25, the tip of the protruding engagement portion 51 and the protrusion portion 11 on the lid portion 6b side face each other and are at approximately the same height.

[0056] Furthermore, the front surface 51a of the protruding engagement portion 51 and the protruding striate portion 11 are not positioned facing each other, and the protruding striate portion 11 is located to the side of the front surface 51a when viewed from the front, but the distance between the part facing the protruding striate portion 11 in the imaginary plane to which the front surface 51a belongs and the protruding striate portion 11 is slightly larger than the sum of the thicknesses of the front surface 14a and the front surface 15a of the slide operation member 7, and is smaller than the standing height of the standing wall portion 14b (the length from the connection part with the front surface 14a to the edge of the free end). Therefore, the front surface 14a (main body member 14) and the front surface 15a (decorative member 15) of the slide operation member 7 can be positioned exactly between the protruding striate portions 11 on the lid portion 6b side.

[0057] As shown in Figures 5, 28(a), and 28(b), the clutch mechanism 42 has a large-diameter gear 40 and a disk member 41. The large-diameter gear 40 has external teeth and a cylindrical structure, and inward protrusions 55 that protrude radially inward are provided on the inner wall of the cylinder at predetermined angular intervals (in this embodiment, 180-degree intervals). Furthermore, an inward flange portion 56 is provided on one axial end face of the large-diameter gear 40. A hole 56a is provided in the center of the inward flange portion 56.

[0058] On the other hand, the disk member 41 has a diameter and thickness large enough to be disposed on the inner periphery of the large-diameter gear 40. A hole 57 is provided in the center of the disk member 41. The disk member 41 is provided with outward biasing protrusions 58 that are biased from the center toward the outer periphery by a compression spring. The biasing protrusions 58 are biased by the compression spring and stop at a position that protrudes slightly outward from the outer periphery of the disk member 41. When the biasing protrusions 58 are pressed toward the center of the disk member 41, the biasing protrusions 58 can retreat inside the disk member 41. The biasing protrusions 58 are provided at predetermined angular intervals on the disk member 41 (at 180-degree intervals in this embodiment).

[0059] Furthermore, an engagement protrusion 60 is provided on the surface of the disc member 41 opposite to the inward flange portion 56 of the large-diameter gear 40. As shown in Figure 28(b), the engagement protrusion 60 is integrated with the disc member 41. The engagement protrusion 60 is also disposed at a central angle of 90 degrees on the disc member 41 relative to the biasing protrusion 58.

[0060] A common shaft is inserted through the hole 56a of the large-diameter gear 40 and the hole 57 of the disk member 41. Furthermore, bearings (not shown) are provided on this common shaft at the positions of the hole 56a and the hole 57, respectively. Therefore, the large-diameter gear 40 and the disk member 41 can rotate independently. When the large-diameter gear 40 and the disk member 41 rotate relative to each other, the inward protrusion 55 on the large-diameter gear 40 and the biasing protrusion 58 on the disk member 41 collide (engage) at a specific angular position. If the rotational force is increased to force the two to rotate relative to each other, the inward protrusion 55 can pass through the biasing protrusion 58 while pushing the biasing protrusion 58 into the disk member 41.

[0061] The large diameter gear 40 engages with a clutch-side gear portion 39b (small gear) of the intermediate gear 39. That is, the power of the motor 38 is transmitted to the large diameter gear 40 via the intermediate gear 39. Also, the engagement protrusion 60 of the disc member 41 engages with the clutch mechanism portion-side engaging portion 49b of the electric-side intervening member 37 shown in FIGS. 5 and 6. That is, the power of the motor 38 is transmitted from the electric-side intervening member 37 to the hub 35 via the clutch mechanism portion 42.

[0062] By having the above-mentioned configuration, the clutch mechanism 42 can transmit the power of the motor 38 to the hub 35 (deadbolt 4 of the electric lock 1) side, and can also cut off the power system on the motor 38 side when manually operating the slide operating member 7 to rotate the hub 35 (deadbolt 4 of the electric lock 1) as described below.

[0063] When the power transmission mechanism 8 is in the state shown in Figures 11 to 15, the slide operation member 7 is lowered as shown in Figure 1(b), and the electric lock 1 is in the unlocked state. When the power transmission mechanism 8 is in the state shown in Figures 16 to 19, the slide operation member 7 is raised as shown in Figure 1(a), and the electric lock 1 is in the locked state.

[0064] Next, the engagement relationship between the housing 6 (lid portion 6b) and the slide operation member 7 will be described. The lid portion 6b of the housing 6 is integrated with the lid-side support member 43, and a small space is formed between them. The slide operation member 7 enters this space and is fixed there. That is, the slide operation member 7 is disposed between the abutment surface 43a of the lid-side support member 43 and the protrusion 11 of the lid portion 6b. At this time, the protruding engagement portion 51 on the lid-side support member 43 side is close to the back side of the front portion 14a of the main body member 14 of the slide operation member 7, and the protrusion 11 on the lid portion 6b side is close to the front side of the front portion 14a.

[0065] The slide operation member 7 can descend until the protruding engagement portion 51 abuts against the inside of the upright wall portion 14b of the main body member 14. In other words, the slide operation member 7 cannot descend beyond the protruding engagement portion 51. The slide operation member 7 can also ascend until the upright wall portion 14b (the engagement portion 31 side) of the main body member 14 abuts against the upper edge 10a of the mounting portion 10 of the lid portion 6b. In other words, the slide operation member 7 cannot ascend beyond the upper edge 10a. Therefore, the slide operation member 7 can move linearly back and forth between a position where the main body member 14 abuts against the upper lid portion 6b (upper edge 10a) and a position where it abuts against the protruding engagement portion 51 below.

[0066] Next, the engagement relationship between the slide operation member 7 and the power transmission mechanism 8 will be described. The slide operation member 7 engages with the hub 35 of the power transmission mechanism 8 via the adapter member 17. Figures 20 to 23 show a state in which the slide operation member 7 and the hub 35 are arranged on both sides of the cover 6b. In Figures 20 to 23, the members are shown spaced apart to make it easier to understand the shapes of each part of each member.

[0067] The slide operation member-side engaging portion 48b of the manual-side intervening member 36 engages with the notch 17a of the adapter member 17 that is integral with the slide operation member 7. This integrates the slide operation member 7 and the manual-side intervening member 36. Furthermore, the hub-side engaging portion 48a of the manual-side intervening member 36 fits into one of the engaging recesses 47 of the hub 35.

[0068] 20(a), 20(b), and 21 show the slide operation member 7 in a lowered state, with the slide operation member 7 and the manual-side intervening member 36 virtually separated on both sides of the cover portion 6b. In the lowered state of the slide operation member 7 shown in FIG. 22(a), the upper edge (engagement portion 31) of the upright wall portion 14b of the main body member 14 abuts against the protruding engagement portion 51. In other words, the slide operation member 7 is in the lower end position.

[0069] 23(a) and 23(b), when the slide operation member 7 is raised, the slide operation member 7 applies a rotational force to the hub 35 via the manual-side intervening member 36, causing the hub 35 to rotate around the shaft 45. At this time, the engagement portion 31 of the upright wall portion 14b of the main body member 14 of the slide operation member 7 abuts against the upper edge 10a of the placement portion 10 of the lid portion 6b. In other words, the slide operation member 7 is in the upper end position.

[0070] The slide operation member 7 can reciprocate along the placement portion 10 of the cover portion 6b (housing 6) between the position shown in Figure 22 and the position shown in Figure 23. The operation of the power transmission mechanism portion 8 at this time will be described with reference to Figures 11 to 19.

[0071] 11 to 15 show the state of the power transmission mechanism 8 when the slide operation member 7 is at the bottom end position. As shown in Figs. 11 to 15, when the slide operation member 7 is in the lower position, the rotational position of the hub 35 is such that the engagement recess 47 of the hub 35, with which the manual-side intervening member 36 engages, is in the lower position.

[0072] At this time, the engagement recess 47 of the hub 35 with which the electric-side intervening member 37 engages is located in an upper position. The electric-side intervening member 37 is engaged with the clutch mechanism 42 and pushes up the engagement protrusion 60 of the disc member 41, causing only the disc member 41 to rotate and moving the electric-side intervening member 37 to the upper position.

[0073] When the slide operation member 7 is operated to move it upward from the state shown in FIGS. 11 to 15, the hub 35 rotates clockwise as viewed in FIG. 11 and stops at the upper end position shown in FIGS. 16 to 19. Meanwhile, the electric-side intervening member 37 is pulled downward as the hub 35 rotates and stops at the lower end position. At that time, the clutch mechanism 42 cuts off power from the motor 38 side, and only the disk member 41 rotates freely. Furthermore, the hub-side engaging portion 48a of the manual-side intervening member 36 and the hub-side engaging portion 49a of the electric-side intervening member 37 move upward or downward together with the engaging recess 47 while sliding slightly relative to the engaging recess 47 of the rotating hub 35.

[0074] Furthermore, when the motor 38 is driven, power is transmitted from the output shaft 38a to the large-diameter gear 40 of the clutch mechanism 42 via the intermediate gear 39. The inward projections 55 and the biasing projections 58 of the large-diameter gear 40 and the disk member 41 engage with each other, causing them to rotate together. As a result, the motor-side intervening member 37 rises or falls, causing the hub 35 to rotate. Therefore, the manual-side intervening member 36 also follows the rotation of the hub 35, and the slide operation member 7 also rises or falls.

[0075] The operation of the power transmission mechanism 8 is shown in Figures 29(a) and 29(b). Figures 29(a) and 29(b) show a simplified view of the positional relationship between the power transmission mechanism 8 and the slide operation member 7. In Figure 29(a), the slide operation member 7 is in a raised position relative to the housing 6 (lid portion 6b), and in Figure 29(b), the slide operation member 7 is in a lowered position. In conjunction with this, the manual-side intervening member 36, hub 35, electric-side intervening member 37, and clutch mechanism 42 (disc member 41) operate smoothly.

[0076] As described above, the power transmission mechanism 8 operates and rotates the hub 35. Then, in conjunction with the rotation of the shaft 45 of the hub 35, the deadbolt 4 of the electric lock 1 protrudes or retracts relative to the door 5 (FIG. 1).

[0077] It is possible to arbitrarily set whether the slide operating member 7 is in the raised or lowered position when the electric lock 1 is locked or unlocked, but in this embodiment, when the slide operating member 7 is in the raised position, the electric lock 1 is in the locked state, and conversely, when the slide operating member 7 is in the lowered position, the electric lock 1 is in the unlocked state.

[0078] Furthermore, although the door 5 (Figure 1) is a left-opening door, in the indoor unit 2 of this embodiment, even if the door 5 opens to the right, when the slide operating member 7 is in the raised position, the electric lock 1 can be set to either the locked state or the unlocked state.

[0079] Next, a procedure for removing the slide operation member 7 from the indoor unit 2 (housing 6) will be described. Normally, the slide operating member 7 is arranged within the arrangement section 10 of the lid section 6b of the housing 6, and as shown in Figures 1(a) and 1(b), it moves up and down within the arrangement section 10, moving the deadbolt 4 of the electric lock 1 forward and backward relative to the door 5 and switching between the locked and unlocked states.

[0080] When moving the slide operation member 7 downward, the curved surface 24 (FIG. 10(b)) of the decorative member 15 of the slide operation member 7 is pressed downward with a finger. When moving the slide operation member 7 upward, the bottom wall 15c (FIG. 10(b)) of the decorative member 15 is pressed upward.

[0081] When it is necessary to remove the slide operation member 7 for some reason, the door 5 is opened and the slide operation member 7 is lowered as shown in FIG. 1(b) to unlock the electric lock 1. When the slide operation member 7 is lowered, a part of the lower part of the slide operation member 7 is exposed from the housing 6. This allows a person to insert a finger into the back side of the slide operation member 7 and press the elastic engagement portion 29 (FIGS. 7(b), 8(b), and 9(b)).

[0082] At this time, as shown in Figure 27, the engagement surface 27a of the holding portion 27 of the decorative element 15 is positioned below the protrusion 11. Therefore, the protrusion 11 does not interfere with the movement of the engagement surface 27a of the decorative element 15 toward the front side. For convenience of explanation, the protrusion 11 is depicted by a solid line in the enlarged portion depicted in Figure 27.

[0083] Then, the elastic engagement portion 29 is pressed with a finger to disengage the engagement surface 18a of the step portion 18 of the main body member 14 from the return portion 29a of the elastic engagement portion 29 of the decorative member 15. When the engagement is released, the decorative member 15 becomes able to swing relative to the main body member 14 around the protrusion 28a at the tip. At this time, as shown in FIG. 10(a), the inclined surface 29b of the elastic engagement portion 29 on the decorative member 15 side abuts on the inclined surface 30 of the reinforcing piece 14d on the main body member 14 side. As a result, the inclined surface 29b slides on the inclined surface 30, and the decorative member 15 becomes inclined relative to the main body member 14, as shown in FIGS. 9(a), 9(b), and 24(a).

[0084] 24(b), since one of the engagements between the main body member 14 and the decorative member 15 has been released, the other engagement (the engagement between the locking portion 22 of the main body member 14 and the protrusion 28a of the decorative member 15) also easily releases, making it possible to remove the decorative member 15 from the main body member 14. In other words, when the slide operation member 7 is moved to a downward position (a specific position), it becomes possible to remove the decorative member 15 from the main body member 14.

[0085] At this time, only the main body member 14 of the slide operation member 7 is restrained by the housing 6. That is, the protruding engagement portion 51 in the space 32 (FIGS. 8(b) and 10(a)) of the main body member 14 abuts on or is close to the engagement portion 31 (standing wall portion 14b) of the main body member 14, and further, the protruding portions 11 of the cover portion 6b abut on or are close to both sides of the front portion 14a. That is, even if an attempt is made to move the slide operation member 7 toward the front, as shown in FIG. 27, the protruding portions 11 face the front portion 14a, and the front portion 14a abuts on the protruding portions 11, preventing the slide operation member 7 from moving forward. Furthermore, even if an attempt is made to move the slide operation member 7 downward to remove it from the housing 6, the engagement portion 31 (standing wall portion 14b) shown in FIG. 7(b), FIG. 10(a), FIG. 25, etc. abuts on the protruding engagement portion 51, preventing the slide operation member 7 from being removed from the housing 6 (cover portion 6b).

[0086] Therefore, as shown in Figure 24(c), the main body member 14 is temporarily raised and housed in the housing 6. At this time, the front surface 14a of the main body member 14 does not face the protrusion 11, as shown in Figure 26. Therefore, the main body member 14 can be moved in the front direction. That is, as shown in Figure 24(d), the main body member 14 can be removed from the housing 6 (lid portion 6b).

[0087] That is, when the main body member 14 is moved to an upper position (a position different from the specific lower position), the main body member 14 can be removed from the housing 6 (lid portion 6b). When the main body member 14 is moved upward, the bottom wall 14c of the main body member 14 is pushed up.

[0088] As explained above, the slide operation member 7 of the indoor unit 2 can be removed from the housing 6 (lid portion 6b) of the indoor unit 2 by first removing the decorative member 15 and then removing the main body member 14.

[0089] Conversely, when attaching the slide operation member 7 to the housing 6, the above-described operations are performed in reverse order. That is, first, the main body member 14 is fitted into the arrangement portion 10 (FIG. 24(c)), and the fitted main body member 14 is moved downward (FIG. 24(b)). Then, the protruding engagement portion 28 is inserted into the gap 21a on the main body member 14 side, and the protruding strip 28a is engaged with the locking portion 22 (FIGS. 10(b) and 24(a)).

[0090] 24(a), when the decorative member 15 is pressed toward the main body member 14, the decorative member 15 swings about the ridge 28a, and the elastic engagement portion 29 on the decorative member 15 side moves on the inclined surface 30 of the reinforcing piece 14d on the main body member 14 side while elastically deforming, and when the turned-back portion 29a passes the inclined surface 30, the elastic engagement portion 29 returns to its natural state, and the turned-back portion 29a engages with the engagement surface 18a of the step portion 18 (FIG. 10(b)). Then, the main body member 14 and the decorative member 15 are integrated, and the slide operation member 7 is attached to the indoor unit 2.

[0091] The indoor unit 2 of the electric lock 1 of this embodiment can also be attached to an existing electric lock together with the outdoor unit 3. In this case, the operating members such as the cylinder and thumb turn of the existing electric lock are removed. Then, a bolt 70 (FIGS. 30 and 31(a)) that passes through the electric lock is inserted into a hole (not shown) provided in the door 5 (FIG. 1), and both units can be integrated and fixed to the door 5.

[0092] The mounting structure of both units will now be described. As shown in FIG. 31 , the indoor unit 2 has a fixed portion 6a of a housing 6. The fixed portion 6a has a hole 66 through which the shaft portion 45 of the hub 35 (FIG. 5) is inserted. Bolt insertion holes 65 are provided on both the left and right sides of the hole 66. The bolt insertion holes 65 are elongated through-holes through which a bolt 70 can be inserted. Both bolt insertion holes 65 are formed to have a generally V-shape. In this embodiment, the bolt 70 can be inserted into both longitudinal positions of the bolt insertion holes 65. In other words, once the bolt 70 is inserted into the bolt insertion hole 65, it does not move along the longitudinal direction within the bolt insertion hole 65, and the bolt 70 and the fixed portion 6a do not move relative to each other, resulting in stable support of the fixed portion 6a (housing 6) by the bolt 70.

[0093] On the other hand, the outdoor unit 3 has a main body 80, a fixing plate 81, an attachment mechanism 82, a support plate 83, and a back plate 84, as shown in FIG. The main body 80 houses the electrical components necessary for locking and unlocking the electric lock 1, and can also house a fixed plate 81. The fixed plate 81 has a fixed portion 81a that fixes the mounting mechanism 82. The fixed portion 81a is a rectangular through-hole in which the mounting mechanism 82 is positioned. As the fixed plate 81 is thick, the posture of the mounting mechanism 82 placed in the fixed portion 81a is stable.

[0094] The mounting mechanism 82 has a base 82a and female screw members 85a, 85b (bolt engagement members). The base 82a includes a mounting portion 86 on which the female screw members 85a, 85b are mounted, and a linear back support portion 87 that supports the back portions of the female screw members 85a, 85b. The back support portion 87 is plate-shaped, with the edge of the plate facing the front. That is, the back support portion 87, which is formed by the edge of the plate, supports the back surfaces of the female screw members 85a, 85b. The back support portion 87 is located above and offset from the axis of the female threads of the female screw members 85a, 85b. That is, the bolt 70, which will be described later, can either be threaded in and stop midway through the female screw, or it can extend beyond the female screw and penetrate the female screw members 85a, 85b.

[0095] The female screw members 85a, 85b are members that function as nuts having female threads that screw onto the bolt 70. Steps 88a, 88b are provided at the top and bottom portions on the front side of the female screw members 85a, 85b, respectively.

[0096] The female screw members 85a, 85b are placed on a mounting portion 86 of the base portion 82a, and the rear sides of the female screw members 85a, 85b are supported by a linear rear support portion 87. The front sides of the female screw members 85a, 85b are supported by a support plate 83. That is, an opening 83a is provided in the support plate 83, and the edges of the opening 83a abut against step portions 88a, 88b of the female screw members 85a, 85b. In other words, the upper and lower portions of the threaded portion of the female screw members 85a, 85b are constrained, and the female screw members 85a, 85b are constrained so as to be immovable toward the front and rear sides. Therefore, the front and rear sides of the female screw members 85a, 85b are fixed so as not to be movable.

[0097] A back plate 84 is attached to the front side of the support plate 83. The back plate 84 is a member that comes into close contact with the door 5. The back plate 84 has an opening 84a that is larger than the opening 83a of the support plate 83.

[0098] When the components of the outdoor unit 3 are assembled, they are attached to the outdoor unit 3 with the female screw members 85a and 85b exposed, as shown in FIG. 31(a). Furthermore, as shown in FIG. 31(b), the female screw members 85a and 85b can be moved left and right along the opening 83a. That is, the spacing between the female screw members 85a and 85b can be changed. This allows the spacing between the female screw members 85a and 85b to be set arbitrarily to correspond to the positions (spacing) of the mounting holes of the existing electric lock, and the outdoor unit 3 and the fixing part 6a (indoor unit 2) can be fastened together with bolts 70, as shown in FIG. 30.

[0099] According to this configuration, by changing the spacing between the female screw members 85a, 85b (bolt engagement members), it is possible to accommodate the spacing between the bolt insertion holes of the electric lock 1 already installed on the door 5 (FIG. 1). In other words, the indoor unit 2 and the outdoor unit 3 can be easily attached to the existing electric lock 1 (door 5).
