Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, the pitch of the mounting holes related to the handle may not match the pitch of the mounting holes related to the object to which the handle is attached. When changing the pitch of the handle to match the pitch of the object to be attached, that is, when producing a plurality of types of handles with different pitches of mounting holes, there has been a problem that the cost increases.

[0005] This invention has been made in view of the above circumstances, and an object thereof is to provide a fixture and a locking device capable of suppressing costs.

Means for Solving the Problems

[0006] To achieve the above object, the fixture of the present invention is A fixture for attaching a handle (handle 10) to a lock case (lock case 60), comprising a main body portion (main body portion 41) formed in an annular and plate shape, and a first attachment portion (first attachment portion 42) consisting of a pair of notches formed at positions symmetric with respect to the center (center O) of the circle on one diameter line (diameter line S1) of the main body portion, wherein the first attachment portion is formed to be long in the radial direction and allows a screw to be inserted therethrough.

[0007] Since there are various intervals between a pair of hole portions related to the lock case, they may not match the interval of the attachment holes related to the handle. Even in such a case, by using a fixture having a first attachment portion formed to be long in the radial direction, the handle can be attached to the lock case. That is, an existing handle can be diverted. By using the fixture according to the present invention, it is not necessary to produce a plurality of types of handles according to the pitch of the mating part. That is, an existing handle can be diverted, and the cost can be reduced.

[0008] Also, the fixture of the present invention further comprises a second attachment portion (second attachment portion 43) consisting of a pair of notches formed at positions symmetric with respect to the center (center O) of the circle on another diameter line (diameter line S2) of the main body portion, wherein the second attachment portion is formed to be long in the radial direction and allows a screw to be inserted therethrough. Also, the another diameter line is orthogonal to the one diameter line.

[0009] The direction in which the attachment holes related to the handle are provided and the direction in which a pair of hole portions related to the lock case are provided may not match. For example, the former may be provided along the left - right direction and the latter may be provided along the up - down direction. Even in such a case where the directions do not match, by using a fixture having the first attachment portion and the second attachment portion, the handle can be attached to the lock case. That is, an existing handle can be diverted. By using the fixture according to the present invention, it is not necessary to produce a plurality of types of handles according to the pitch of the mating part and the direction in which the holes are provided. That is, an existing handle can be diverted, and the cost can be reduced.

[0010] Also, in the fixture of the present invention, the pair of notches related to the first mounting portion open inward in the radial direction, and the pair of notches related to the second mounting portion open outward in the radial direction.

[0011] By making the opening directions of the pair of notches different, with the first mounting portion having an opening inward in the radial direction and the second mounting portion having an opening outward in the radial direction, it is possible to make the pitches (the intervals between the pair of hole portions in the lock case) that can be accommodated by the first mounting portion and the second mounting portion different. In other words, it is possible to accommodate a wider range of pitches (more types of lock cases). The first mounting portion can accommodate a smaller pitch than the second mounting portion, and the second mounting portion can accommodate a larger pitch than the first mounting portion. The operator can appropriately select whether to use the first mounting portion or the second mounting portion according to the interval between the pair of hole portions in the lock case.

[0012] Also, the fixture of the present invention can screw screws into a pair of screw holes arranged at an interval of 30 mm to 46 mm via the first mounting portion, and can screw screws into a pair of screw holes arranged at an interval of 36 mm to 52 mm via the second mounting portion.

[0013] When the interval between the pair of hole portions in the lock case is small (for example, 32 mm), the operator can attach the handle to the lock case using the first mounting portion. Also, when the interval between the pair of hole portions in the lock case is large (for example, 48 mm), the operator can attach the handle to the lock case using the second mounting portion.

[0014] Also, the lock device of the present invention includes an outdoor handle (outdoor handle 20), an indoor handle (indoor handle 30), two fixtures (fixture 40), two first pipes (first pipe 7), and two second pipes (second pipe 8). The outdoor handle includes a pair of bosses (boss 23), and the distance between the screw holes of the pair of bosses is a first distance. The indoor handle includes a pair of screw holes (screw holes 33) provided at positions facing the pair of bosses. The fixture enables attachment to the lock case (lock case 60) of the outdoor handle and the indoor handle. A pair of hole portions (hole portions 61) are formed in the lock case at a second distance different from the first distance. The fixture includes a main body portion (main body portion 41) formed in an annular and plate shape, and a first attachment portion (first attachment portion 42) composed of a pair of notches formed at positions symmetric with respect to the center (center O) of the circle on one diameter line (diameter line S1) of the main body portion. The first attachment portion is formed to be long in the radial direction and allows screws to be inserted therethrough. One of the fixtures is configured to be screwed and fixed to the pair of bosses of the outdoor handle via the first attachment portion. The first pipe is arranged at the second distance in the first attachment portion of one of the fixtures and is configured to be screwed and fixed. The first pipe can be inserted into the pair of hole portions of the lock case. Screws can be inserted into the pair of hole portions of the lock case through the first attachment portion of the other fixture and screwed into the first pipe. The second pipe is arranged at the first distance in the first attachment portion of the other fixture and is configured to be screwed and fixed. The other fixture is configured to be fixed to the indoor handle by screwing the screws inserted from the pair of screw holes of the indoor handle into the second pipe.

[0015] The distance between a pair of holes in the lock case may be a second distance and may not match the distance (first distance) of the mounting holes in the handle. Even in this case, by using a fixture having a first mounting portion formed to be long in the radial direction, the handle can be attached to the lock case. That is, an existing handle can be diverted. According to the lock device of the present invention, it is not necessary to produce a plurality of types of handles according to the pitch of the mating part. That is, an existing handle can be diverted, and the cost can be reduced.

[0016] Also, in the lock device of the present invention, The fixture further includes a second mounting portion (second mounting portion 43) formed by a pair of notches formed at positions symmetric with respect to the center (center O) of the circle on another diameter line (diameter line S2) of the main body portion. The second mounting portion is formed to be long in the radial direction and a screw can be inserted therethrough. Further, the other diameter line is orthogonal to the one diameter line.

[0017] The direction in which the mounting holes in the handle are provided and the direction in which a pair of holes in the lock case are provided may not match. For example, the former may be provided along the left-right direction and the latter may be provided along the up-down direction. Even in such a case where the directions do not match, by using a fixture having the first mounting portion and the second mounting portion, the handle can be attached to the lock case. That is, an existing handle can be diverted. According to the lock device of the present invention, it is not necessary to produce a plurality of types of handles according to the pitch of the mating part or the direction in which the holes are provided. That is, an existing handle can be diverted, and the cost can be reduced.

[0018] Also, in the lock device of the present invention, The pair of notches related to the first mounting portion open inward in the radial direction, The pair of notches related to the second mounting portion open outward in the radial direction.

[0019] By making the opening directions of the pair of notches different, with the first mounting portion being an opening towards the inner diameter side and the second mounting portion being an opening towards the outer diameter side, it is possible to make the pitches (the distances between the pair of hole portions in the lock case) that can be accommodated by the first mounting portion and the second mounting portion different. In other words, it is possible to accommodate a wider range of pitches (more types of lock cases). The first mounting portion can accommodate a smaller pitch than the second mounting portion, and the second mounting portion can accommodate a larger pitch than the first mounting portion. The operator can appropriately select whether to use the first mounting portion or the second mounting portion according to the distance between the pair of hole portions in the lock case.

[0020] Also, in the lock device of the present invention, It is possible to screw a screw into a pair of screw holes arranged at an interval of 30 mm to 46 mm via the first mounting portion, and it is possible to screw a screw into a pair of screw holes arranged at an interval of 36 mm to 52 mm via the second mounting portion.

[0021] When the distance between the pair of hole portions in the lock case is small (for example, 32 mm), the operator can attach the handle to the lock case using the first mounting portion. Also, when the distance between the pair of hole portions in the lock case is large (for example, 48 mm), the operator can attach the handle to the lock case using the second mounting portion.

[0024] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Regarding terms used in this specification that specify shapes, geometric conditions, and their degrees, such as terms like "parallel", "perpendicular", "identical", "right angle", etc., and values of lengths and angles, they are not bound by strict meanings and are to be interpreted to include ranges where similar functions can be expected.

[0025] First, the handle 10 used in the locking device according to this embodiment will be described. As shown in FIG. 1, the handle 10 is attached to the door 2. The handle 10 includes an outdoor handle 20 and an indoor handle 30. The outdoor handle 20 is attached to the outdoor side surface of the door 2. The indoor handle 30 is attached to the indoor side surface of the door 2. The handle 10 is a lever-type handle and can perform a pivoting operation (rotation operation) with the attachment portion side (fixed side) to the door 2 as the rotation center.

[0026] As shown in FIG. 1, a box-shaped locking case 50 (locking box) is arranged (fixed) inside the door 2. The locking case 50 is configured to receive an input from the handle 10. A locking mechanism is housed in the locking case 50. Examples of the locking mechanism include a mechanism for advancing and retracting the latch 3. The latch 3 protrudes from the door end and is inserted into a strike (not shown) provided on the door frame when the handle 10 is not being pivoted. The latch 3 retracts and exits the strike when the handle 10 is pivoted and is housed inside the locking case 50.

[0027] The handle 10 is an electronic lock. Although not shown, the outdoor handle 20 is provided with an input unit. Examples of the input unit include a biometric authentication unit (e.g., fingerprint authentication, face authentication, iris authentication), an IC card authentication unit, a password input unit (numeric keypad), a two-dimensional code input unit, etc. The input unit is connected to a control unit (not shown) of the handle 10 by wire or wireless (wireless communication). When the control unit determines that the information input via the input unit of the outdoor handle 20 is correct, it controls the door 2 to be in an unlocked state. The control unit, for example, retracts (exits) a deadbolt (not shown) from the strike to realize an unlocked state. When entering the room, the user first inputs information via the input unit of the outdoor handle 20 to make the door 2 in an unlocked state. Then, the user pivots the outdoor handle 20 to open the door 2.

[0028] After the control unit sets the door 2 to the unlocked state, when it detects the closing of the door 2, it determines that the locking condition is satisfied based on the elapse of a predetermined time after the closing of the door 2, and controls the door 2 to be in the locked state (so-called auto-lock). For example, the control unit inserts the deadbolt into the strike to realize the locked state.

[0029] When the indoor handle 30 is rotated in the state where the door 2 is locked, the locking of the door 2 is released. Therefore, when the user leaves the room, the user can unlock the door by simply rotating the indoor handle 30 and open the door 2.

[0030] As shown in FIG. 1, the vertical direction of the door 2 is the up-down direction, the horizontal direction of the door 2 is the left-right direction, and the thickness direction of the door 2 is the front-back direction.

[0031] FIG. 2 is a perspective view of the outdoor handle 20, the indoor handle 30, and the lock case 50 as viewed from above, with the door 2 not shown. The outdoor handle 20 includes a bottomed cylindrical base 21 and a substantially L-shaped grip portion 22. The base 21 is a portion to be attached (fixed) to the mating part (door 2, lock case 50). The grip portion 22 is inserted through an opening provided at the center of the bottom surface of the base 21. The grip portion 22 is rotatable within a predetermined range about the center of the circular base 21 as an axis (rotation axis).

[0032] The base 21 includes a pair of bosses 23 extending from the bottom surface toward the mating part side (that is, extending along the rotation axis direction of the handle). The pair of bosses 23 are provided at intervals in the left-right direction. The bosses 23 are provided with screw holes. Here, the interval between the screw holes of the pair of bosses 23 is defined as the "first interval". Note that the interval between the screw holes refers to the distance (center-to-center distance) from the center of one screw hole to the center of the other screw hole, rather than the minimum distance between the holes.

[0033] As shown in FIG. 2, the indoor handle 30 includes a bottomed cylindrical base portion 31 and a substantially L-shaped grip portion 32. The base portion 31 is a portion to be attached (fixed) to the mating member (door 2, lock case 50). The grip portion 32 is inserted into an opening provided at the center of the bottom surface of the base portion 31. The grip portion 32 is rotatable within a predetermined range about the center of the circular base portion 31 as an axis (rotation axis).

[0034] The base portion 31 is provided with a pair of screw holes 33 penetrating in the rotation axis direction of the handle. The pair of screw holes 33 are provided at positions facing a pair of bosses 23 (screw holes) of the outdoor handle 20. Therefore, the interval (center-to-center distance) between the pair of screw holes 33 is the first interval. Note that a pair of screw holes 33 (through holes) are formed in the base portion 31, and no boss similar to the boss 23 is provided.

[0035] In the present embodiment, the first interval is 42 mm.

[0036] Here, a case where the handle 10 (outdoor handle 20 and indoor handle 30) is attached to a mating member (door 2, lock case 50) with a pitch of 42 mm will be described. Hereinafter, the mating member will be described as the lock case 50, but the door 2 is configured in the same manner. As shown in FIG. 2, the lock case 50 includes a pair of hole portions 51 provided apart in the left-right direction. The hole portions 51 are through holes. The pitch of 42 mm means that the interval (center-to-center distance) between the pair of hole portions 51 is 42 mm. In this case, it can be said that the interval between the pair of hole portions 51 is the first interval.

[0037] First, as shown in FIG. 3, the operator attaches two pipes 4 to a pair of bosses 23 of the outdoor handle 20 using two set screws 3. The pipe 4 has an internal thread (thread) formed on its inner surface (inner circumferential surface). Next, the operator inserts the pair of pipes 4 into a pair of holes 51 of the lock case 50. Next, as shown in FIG. 4, the operator inserts two screws 5 from the outside into a pair of screw holes 33 of the indoor handle 30, further inserts them into a pair of holes 51 of the lock case 50, and screws the screws 5 into the pipes 4 inside the holes. Thereby, the outdoor handle 20 and the indoor handle 30 are attached to the lock case 50.

[0038] By the way, there are those with a pitch (the distance between a pair of holes) other than 42 mm among the mounting partners of the handle 10. For example, there are those with a pitch of 32 mm and those with a pitch of 50 mm. In addition, the pair of holes of the mounting partner may be provided at a distance in the vertical direction instead of being provided at a distance in the left - right direction. When producing the handle 10 in accordance with the pitch interval and direction of the mounting partner, that is, when producing a plurality of handles 10 with different positions of bosses and screw holes, problems such as the need to manufacture a plurality of molds and an increase in variations occur, resulting in an increase in manufacturing costs and management costs. Also, when performing processing to provide holes with a first interval in the mounting partner in accordance with the first interval (42 mm in the left - right direction) of the handle 10, problems such as an increase in cost occur.

[0039] The lock device according to the present embodiment enables a handle 10 with a distance between a pair of bosses 23 (a pair of screw holes 33) of a first interval (42 mm in the left - right direction) to be attached to a mounting partner with a pitch other than 42 mm without providing new holes in the mounting partner.

[0040] As shown in Fig. 5, the locking device 100 according to this embodiment mainly includes an outdoor handle 20, an indoor handle 30, two fixtures 40, two first pipes 7, and two second pipes 8. The fixture 40 is a member that enables the attachment of the handle 10 (outdoor handle 20 and indoor handle 30) to the attachment partner (lock case). Further, the inner surfaces (inner circumferential surfaces) of the first pipe 7 and the second pipe 8 are formed with internal threads (thread grooves) and can be screwed with screws (female screws).

[0041] Fig. 6(a) is a plan view (axial direction view) of one surface (first surface T1) of the fixture 40 (handle side). Fig. 6(b) is a plan view (axial direction view) of the other surface (second surface T2) of the fixture 40 (lock case side). The fixture 40 includes a main body portion 41 formed in an annular and plate shape, and a first attachment portion 42 formed by a pair of notches formed at positions symmetric with respect to the center O of the circle on one diameter line (diameter line S1) in the main body portion 41. The first attachment portion 42 is elongated in the radial direction (slit-shaped, long hole-shaped). Further, the first attachment portion 42 can insert a screw. Specifically, it can insert the threaded portion of a predetermined screw and has a size that does not allow the head of the screw to pass through.

[0042] The pair of notches related to the first attachment portion 42 open inward in the radial direction. It is possible to screw a screw into a pair of screw holes (a pair of hole portions of the attachment partner) arranged at an interval (pitch) of 30 mm to 46 mm via the first attachment portion 42.

[0043] The fixture 40 includes a second attachment portion 43 formed by a pair of notches formed at positions symmetric with respect to the center O of the circle on another diameter line (diameter line S2) in the main body portion 41. The second attachment portion 43 is elongated in the radial direction (slit-shaped, long hole-shaped). Further, the second attachment portion 43 can insert a screw. Specifically, it can insert the threaded portion of a predetermined screw and has a size that does not allow the head of the screw to pass through.

[0044] Another diameter line S2 is orthogonal to one diameter line S1. A pair of notches related to the second attachment part 43 open outward in the radial direction. It is possible to screw screws into a pair of screw holes (a pair of hole parts of the mating part) arranged at intervals (pitches) between 36 mm and 52 mm via the second attachment part 43. The second attachment part 43 can accommodate a larger pitch than the first attachment part 42.

[0045] The thickness of the fixture 40 is approximately 2 mm. Also, the fixture 40 is made of metal (for example, stainless steel). The outer diameter of the fixture 40 is, for example, approximately 58 mm. The inner diameter of the fixture 40 is, for example, approximately 28 mm.

[0046] Next, the case of attaching the handle 10 to a mating part (lock case 60: a specific lock case) with a pitch of 32 mm will be described. As shown in FIG. 7, the lock case 60 includes a pair of hole parts 61 provided at intervals in the left - right direction, and the interval (center - to - center distance) between the pair of hole parts 61 is 32 mm (second interval), which is different from the first interval. In this case, the second interval is smaller than the first interval.

[0047] (Step 1) Since the pitch of the mating part is 32 mm, the operator decides to use the first attachment part 42 of the fixture 40 instead of the second attachment part 43. As shown in FIG. 8, two first pipes 7 are arranged at the second interval on the first attachment part 42 of the fixture 40 and fixed (screw - tightened and fixed) using screws P1 (predetermined screws) respectively. The second interval related to the two first pipes 7 is the distance from the center of one first pipe 7 to the center of the other first pipe 7. The operator arranges the first pipe 7 on the second surface T2 side of the fixture 40 so that the first pipe 7 is fixed (the first pipe 7 protrudes) on the second surface T2 side and performs screw - tightening from the first surface T1 side.

[0048] (Step 2) Next, as shown in FIG. 9, the operator screws and fixes the fixture 40 to which the first pipe 7 is fixed to the outdoor handle 20. Specifically, two screws P2 (predetermined screws) are inserted from the second surface T2 side of the fixture 40 through the first attachment portion 42 into a pair of bosses 23 (screw holes thereof) and screwed in. At this time, on the first surface T1 side of the fixture 40, the edges of the boss 23 and the first attachment portion 42 come into contact with each other. However, as shown in FIG. 6(a), a substantially circular recess T (dip, inclined surface) is provided at the edge portion. The recess T is formed at a position corresponding to the first interval (42 mm). By providing the recess T, alignment with the boss 23 becomes easy.

[0049] (Step 3) Next, the operator inserts the pair of first pipes 7 into a pair of hole portions 61 (see FIG. 7) of the lock case 60.

[0050] (Step 4) Next, as shown in FIG. 10, the operator arranges the two second pipes 8 at the first interval in the first attachment portion 42 of another fixture 40 and fixes (screws and fixes) them using screws P3 (predetermined screws) respectively. The first interval related to the two second pipes 8 is the distance from the center of one second pipe 8 to the center of the other second pipe 8. The operator arranges the second pipes 8 on the first surface T1 side so that the second pipes 8 are fixed (the second pipes 8 protrude) on the first surface T1 side of the fixture 40 and performs screw tightening from the second surface T2 side. Note that the length of the second pipe 8 is shorter than the length of the first pipe 7.

[0051] (Step 5) Next, as shown in FIG. 11, the operator screws and fixes the fixture 40 to which the second pipe 8 is fixed to the lock case 60. Specifically, two screws P4 (predetermined screws) are inserted from the first surface T1 side of the fixture 40 through the first attachment portion 42 into a pair of hole portions 61, and the screws P4 are screwed into the first pipe 7 inside the holes. At this time, the interval (center - to - center distance) between the two screws P4 becomes the second interval.

[0052] (Step 6) Next, as shown in FIG. 12, the operator inserts two screws P5 (predetermined screws) through a pair of screw holes 33 of the indoor handle 30 into the second pipe 8 and tightens them. As a result, the indoor handle 30 is attached to the fixture 40 (lock case 60). In other words, the fixture 40 that has fixed the second pipe 8 is fixed (screw-fastened) to the indoor handle 30.

[0053] By executing Steps 1 to 6, the handle 10 (outdoor handle 20 and indoor handle 30) can be attached to the mating member (lock case 60) with a pitch of 32 mm.

[0054] In Step 1 described above, since the pitch of the mating member is 32 mm, the operator decided to use the first attachment portion 42. Although not shown, when the pitch of the mating member is 50 mm in the left-right direction, the operator decides to use the second attachment portion 43 and executes Steps 1 to 6 using the second attachment portion 43. At this time, the second interval is 50 mm. The operator can select whether to use the first attachment portion 42 or the second attachment portion 43 according to the pitch of the mating member.

[0055] In the present embodiment, the fixture 40 is provided with both the first attachment portion 42 and the second attachment portion 43, but it may be configured to include only one of them. For example, when the mating member is the lock case 60 (see FIG. 7) with a pitch of 32 mm, as described above, the handle 10 can be attached using only the first attachment portion 42. Therefore, the fixture 40 may be provided with only the first attachment portion 42 and not the second attachment portion 43.

[0056] Next, although not shown, the case where the handle 10 is attached to a mating member (lock case) with a pitch of 48 mm in the vertical direction will be described. The lock case includes a pair of holes provided at a distance in the vertical direction, and the interval (center-to-center distance) between the pair of holes is 48 mm (second interval).

[0057] (Step 11) Since the pitch of the mating part is 48 mm in the vertical direction, the operator decides to use both the first mounting portion 42 and the second mounting portion 43 for the fixture 40. Two first pipes 7 are arranged at a second interval on the second mounting portion 43 of the fixture 40 and fixed (screwed and fixed) using screws P1 (predetermined screws) respectively. The operator arranges the first pipe 7 on the second surface T2 side so that the first pipe 7 is fixed (the first pipe 7 protrudes) on the second surface T2 side of the fixture 40, and performs screw tightening from the first surface T1 side.

[0058] (Step 12) Next, the operator screws and fixes the fixture 40 with the first pipe 7 fixed to the outdoor handle 20. Specifically, two screws P2 (predetermined screws) are inserted into a pair of bosses 23 (screw holes) through the first mounting portion 42 from the second surface T2 side of the fixture 40 and screwed in.

[0059] (Step 13) Next, the operator inserts a pair of first pipes 7 into a pair of hole portions of the lock case.

[0060] (Step 14) Next, the operator arranges two second pipes 8 at a first interval on the first mounting portion 42 of another fixture 40 and fixes (screws and fixes) them using screws P3 (predetermined screws) respectively. The operator arranges the second pipe 8 on the first surface T1 side so that the second pipe 8 is fixed (the second pipe 8 protrudes) on the first surface T1 side of the fixture 40, and performs screw tightening from the second surface T2 side.

[0061] (Step 15) Next, the operator screws and fixes the fixture 40 with the second pipe 8 fixed to the lock case. Specifically, two screws P4 (predetermined screws) are inserted into a pair of hole portions of the lock case through the second mounting portion 43 from the first surface T1 side of the fixture 40, and the screws P4 are screwed into the first pipe 7 inside the hole. At this time, the interval (center - to - center distance) between the two screws P4 is the second interval (48 mm).

[0062] (Step 16) Next, the operator inserts two screws P5 (predetermined screws) into the second pipe 8 through a pair of screw holes 33 of the indoor handle 30 and tightens them. As a result, the indoor handle 30 is attached to the fixture 40 (lock case). In other words, the fixture 40 that has fixed the second pipe 8 is fixed (screw-fastened) to the indoor handle 30.

[0063] By executing Steps 11 to 16, the handle 10 (outdoor handle 20 and indoor handle 30) can be attached to an attachment target (lock case) with a pitch of 48 mm in the vertical direction.

[0064] In the present embodiment, it is assumed that a pair of notches related to the first attachment portion 42 open radially inward and a pair of notches related to the second attachment portion 43 open radially outward. However, as a modification, the first attachment portion 42 and the second attachment portion 43 may both be configured to open radially inward. Further, the first attachment portion 42 and the second attachment portion 43 may both be configured to open radially outward.

[0065] The fixture (fixture 40) of the present embodiment is a fixture for attaching a handle (handle 10) to a lock case (lock case 60), and includes a main body portion (main body portion 41) formed in an annular and plate shape, and a first attachment portion (first attachment portion 42) formed by a pair of notches formed at positions symmetric with respect to the center (center O) of the circle on one diameter line (diameter line S1) of the main body portion. The first attachment portion is formed to be long in the radial direction and allows a screw to be inserted therethrough.

[0066] Since there are various intervals between a pair of hole portions related to the lock case, they may not match the interval of the attachment holes related to the handle. Even in such a case, by using a fixture having a first attachment portion formed to be long in the radial direction, the handle can be attached to the lock case. That is, an existing handle can be diverted. By using the fixture according to the present embodiment, it is not necessary to produce a plurality of types of handles according to the pitch of the attachment target. That is, an existing handle can be diverted and the cost can be reduced.

[0067] In addition, the fixture of the present embodiment further includes a second attachment portion (second attachment portion 43) formed by a pair of notches formed at positions symmetric with respect to the center (center O) of the circle on another diameter line (diameter line S2) of the main body portion.

[0068] There may be a case where the direction in which the attachment hole for the handle is provided does not match the direction in which the pair of hole portions for the lock case are provided. For example, the former may be provided along the left - right direction, and the latter may be provided along the up - down direction. Even in such a case where the directions do not match, by using the fixture having the first attachment portion and the second attachment portion, the handle can be attached to the lock case. That is, an existing handle can be diverted. By using the fixture according to the present embodiment, it is not necessary to produce a plurality of types of handles according to the pitch of the attachment target and the direction in which the holes are provided. That is, an existing handle can be diverted, and the cost can be suppressed.

[0069] In addition, in the fixture of the present embodiment, the pair of notches related to the first attachment portion open inward in the radial direction, and the pair of notches related to the second attachment portion open outward in the radial direction.

[0073] The lock device (lock device 100) of this embodiment includes an outdoor handle (outdoor handle 20), an indoor handle (indoor handle 30), two fixtures (fixture 40), two first pipes (first pipe 7), and two second pipes (second pipe 8). The outdoor handle includes a pair of bosses (boss 23), and the interval between the screw holes of the pair of bosses is a first interval. The indoor handle includes a pair of screw holes (screw hole 33) provided at a position facing the pair of bosses. The fixture enables attachment to the lock case (lock case 60) of the outdoor handle and the indoor handle, and a pair of hole portions (hole portion 61) are formed in the lock case at a second interval different from the first interval. The fixture includes a main body portion (main body portion 41) formed in an annular and plate shape, and a first mounting portion (first mounting portion 42) composed of a pair of notches formed at positions symmetric with respect to the center (center O) of the circle on one diameter line (diameter line S1) of the main body portion. The first mounting portion is formed to be long in the radial direction and allows screws to be inserted therethrough. One of the fixtures is configured to be screwed and fixed to the pair of bosses of the outdoor handle via the first mounting portion. In the first mounting portion of the one fixture, the first pipe is arranged at the second interval and is to be fixed by screwing, and the first pipe can be inserted into the pair of holes in the lock case. It is possible to insert a screw into the pair of holes in the lock case through the first mounting portion of the other fixture and screw the screw into the first pipe. In the first mounting portion of the other fixture, the second pipe is arranged at the first interval and is to be fixed by screwing. The other fixture is configured to be fixed to the indoor handle by screwing a screw inserted from the pair of screw holes of the indoor handle into the second pipe.

[0074] The interval between the pair of holes in the lock case may be the second interval and may not match the interval (first interval) of the mounting holes in the handle. Even in this case, by using a fixture having a first mounting portion formed to be long in the radial direction, the handle can be attached to the lock case. That is, an existing handle can be diverted. According to the lock device according to the present embodiment, it is not necessary to produce a plurality of types of handles according to the pitch of the attachment target. That is, an existing handle can be diverted, and the cost can be suppressed.

[0075] Also, in the lock device of the present embodiment, The fixture further includes a second mounting portion (second mounting portion 43) formed by a pair of notches formed at positions symmetric with respect to the center (center O) of the circle on another diameter line (diameter line S2) of the main body portion.
