The lower end of the lever 6 is supported by the grip 34 via a swing shaft 35 having the left - right direction as the axial direction. On the rear side of the upper part of the grip 34, a holder 40 (see FIGS. 3, 4, 8, and 9) is provided. The upper end of the latch lever 42 (see FIGS. 3 and 4) is supported by the holder 40 via a swing shaft 43 having the left - right direction as the axial direction. A long hole 44 having the vertical direction as the longitudinal direction is provided at the lower end of the latch lever 42 (see FIG. 4). Long holes 41 having the front - rear direction as the longitudinal direction are provided on the left and right side surfaces of the holder 40 (see FIGS. 3, 8, and 9). Pins 6a having the left - right direction as the longitudinal direction project from the left and right side surfaces of the upper end of the lever 6 (see FIGS. 3, 4, 8, and 9). Both ends of the pin 6a are arranged inside the long hole 41 of the holder 40 and slide along the long hole 41. Also, the long hole 41 restricts the swing range of the lever 6. Further, the pin 6a is arranged inside the long hole 44 of the latch lever 42 and swings the latch lever 42. When the lever 6 swings counterclockwise in FIG. 4 around the swing shaft 35, the pin 6a pushes the lower part of the latch lever 42 forward through the long hole 44, and the latch lever 42 swings clockwise around the swing shaft 43. By the swing of the latch lever 42, the latch lock 7 operates and the latch bolt 7a retreats inside the door opening 2a.

[0018] On the back surface of the holder 40, female threads 47 having the front - rear direction as the axial direction are provided at two positions in the vertical direction. The indoor - side handle 3 is fastened to the female threads 47 using male threads (not shown).

[0019] A flange 43F (see FIG. 9) is provided at one end (in this embodiment, the left end) of the swing shaft 43. A retaining means 43R (see FIG. 8) is provided at the other end (in this embodiment, the right end) of the swing shaft 43. The retaining means 43R is, for example, a retaining ring (such as an E - ring) and is attached to a groove (not shown) formed in the circumferential direction on the swing shaft 43. Note that the retaining means 43R may also be a snap pin or the like.

[0020] A flange 6F (see Figure 9) is provided at one end of the pin 6a (the left end in this embodiment). A retaining means 6R (see Figure 8) is provided at the other end of the pin 6a (the right end in this embodiment). The retaining means 6R is, for example, a retaining ring (such as an E-ring) and is fitted into a groove (not shown) formed circumferentially on the pin 6a. The retaining means 6R may also be a snap pin or the like.

[0021] [First pedestal] The first base 31 supports one end (the upper end in this embodiment) of the grip 34. The first base 31 is positioned on the exterior wall surface 2c of the door 2 via a sealing material 36 (see Figure 3) made of resin or the like. A housing section 60 (see Figures 8 and 9) that opens forward is provided at the location of the first base 31 opposite the end of the grip 34, and the holder 40 is housed in the housing section 60. Above the housing section 60, a through hole 61 is provided, into which the front part of the first electric lock 9 is housed. The through hole 61 is covered with a removable cover 63 (see Figures 1 to 4). The cover 63 and the front surface of the grip 34 have a continuous arch shape.

[0022] Engaging portions 62 are provided on the left and right side walls of the housing portion 60. Engaged portions 45 are provided on the left and right side walls of the holder 40. The left and right engaging portions 62 are positioned further outward in the left-right direction than the left and right engaged portions 45. The rear ends of the engaging portions 62 are integral with the side walls of the housing portion 60, and the portions in front of the rear ends of the engaging portions 62 are elastically deformable in the left-right direction. The front ends of the left and right engaging portions 62 have protrusions 62T that project to the right and left, respectively. The engaged portions 45 are holes or recesses. When the holder 40 is inserted into the housing portion 60 from the front, the engaging portions 62 engage with the engaged portions 45, thereby fixing the grip 34 to the first base 31.

[0023] [Second pedestal] The second base 32 supports the other end (the lower end in this embodiment) of the grip 34. The second base 32 has a structure that is the first base 31 inverted vertically, and is equipped with the same housing portion 60, through hole 61, engaging portion 62, and cover 63 as the first base 31, but a description of these structures will be omitted.

[0024] [First electric lock] Above the grip 34, a first electric lock 9 (see Figure 1) is provided for extending and retracting the deadbolt 9a. The first electric lock 9 includes, for example, a cylinder lock 9c and a drive device 9d such as a motor that drives the cylinder lock 9c. A keyhole (not shown) is provided at the front end of the first electric lock 9, and a thumbturn 9b is provided at the rear end. The front end of the first electric lock 9 is surrounded by a first base 31.

[0025] [Second electric lock] Below the grip 34, a second electric lock 10 is provided for extending and retracting the deadbolt 10a. The second electric lock 10 includes, for example, a cylinder lock 10c and a drive device 10d such as a motor that drives the cylinder lock 10c. A keyhole (not shown) is provided at the front end of the second electric lock 10, and a thumbturn 10b is provided at the rear end. The front end of the second electric lock 10 is surrounded by a second base 32.

[0026] [Second Authentication Device] The second authentication device 8 includes a control device 50 that communicates with an external communication medium and controls the first electric lock 9 and the second electric lock 10, and a push button 51 exposed from the front of the grip 34. The control device 50 has a reading function that reads authentication information from a contactless IC card (not shown), an authentication function that determines whether the read authentication information is correct, and a control function that controls the drive devices 9d and 10d according to the authentication result.

[0027] A person (user) attempting to enter from the outside presses the push button 51 and then holds the IC card near the push button 51. Communication then takes place between the IC card and the control device 50, and the authentication information on the IC card is read by the control device 50. The control device 50 determines whether the read authentication information matches specific authentication information that has been stored in advance. If a match is determined, the control device 50 outputs an unlock signal to the first electric lock 9 and the second electric lock 10, and the first electric lock 9 and the second electric lock 10 are unlocked. On the other hand, if a match is determined, no unlock signal is sent, and the first electric lock 9 and the second electric lock 10 are not unlocked. The covers 63 of the first base 31 and the second base 32 can be removed, and the first electric lock 9 and the second electric lock 10 can be locked and unlocked using a key (not shown).

[0028] [Third pedestal] Figure 5 is a side view showing the locking device 1 with the third base 33 and the second base 32. Figure 6 is an exploded view showing the locking device 1 with the third base 33 and the second base 32. Figure 7 is a cross-sectional view showing the locking device 1 with the third base 33 and the second base 32.

[0029] The third base 33 is interchangeable with at least one of the first base 31 and the second base 32. In this embodiment, the case in which the first base 31 and the third base 33 are interchangeable will be described. Here, interchangeability means that either the first base 31 or the third base 33 can be attached to the door 2 and the grip 34 without modifying the door 2 or the grip 34.

[0030] The third base 33 supports one end (the upper end in this embodiment) of the grip 34. The third base 33 is positioned on the exterior wall surface 2c of the door 2 via a sealing material 36 (see Figure 6) made of resin or the like. The third base 33 also has a housing portion 60, a through hole 61, and an engaging portion 62 similar to the first base 31 (not shown), but a description of these structures is omitted.

[0031] The through-hole 61 is covered by a removable cover 73. The front of the cover 73 and the grip 34 have a continuous arch shape. The portion above the through-hole 61 is longer than the first base 31 and houses the first authentication device 75. The first authentication device 75 is one of the following, for example, a keypad or a biometric authentication device (facial recognition, fingerprint recognition). The keypad accepts the input of a PIN. In the case of facial recognition, the first authentication device 75 has a function to capture a photograph of the face. In the case of fingerprint recognition, the first authentication device 75 has a function to read a fingerprint.

[0032] A connector 46 is provided at the upper end of the holder 40. The connector 46 is wired to the control device 50. Meanwhile, the terminal 74 of the first authentication device 75 is provided on the third base 33. The terminal 74 and the connector 46 are facing each other in the front-to-back direction, that is, in the direction in which the grip 34 is attached to the third base 33. Therefore, when the grip 34 is attached to the third base 33, the terminal 74 is connected to the connector 46 at the same time.

[0033] A person (user) attempting to enter from the outside presses the push button 51 and then uses the first authentication device 75 to input authentication information (such as a PIN, facial image, or fingerprint image). The control device 50 determines whether the input authentication information matches specific authentication information that has been stored in advance. If a match is determined, the control device 50 outputs an unlock signal to the first electric lock 9 and the second electric lock 10, and the first electric lock 9 and the second electric lock 10 are unlocked. On the other hand, if a match is determined, no unlock signal is sent, and the first electric lock 9 and the second electric lock 10 are not unlocked.

[0034] The lock device 1 according to the embodiment described above comprises a first base 31 and a second base 32 provided on the door 2 at a distance from each other, a grip 34 spanning the first base 31 and the second base 32, a third base 33 interchangeable with at least one of the first base 31 and the second base 32, a lock (first electric lock 9, second electric lock 10), a first authentication device 75 provided on the third base 33 for authenticating the user, and drive devices 9d and 10d for driving the lock according to the authentication result by the first authentication device 75. With this configuration, an authentication device (first authentication device 75) can be easily added to the lock device 1.

[0035] For example, when installing a new locking device 1, if the user desires the first authentication device 75, the locking device 1 is installed using the first base 31 and the third base 33, or the second base 32 and the third base 33. Since the third base 33 is compatible with at least one of the first base 31 and the second base 32, the locking device 1 can be installed with the same ease as when using the first base 31 and the second base 32. On the other hand, if the user does not desire the first authentication device 75, the locking device 1 is installed using the first base 31 and the second base 32. In other words, according to this embodiment, both a specification with the first authentication device 75 and a specification without the first authentication device 75 are provided, and the user can freely choose either specification. Furthermore, since the only difference between the two specifications is the base, the two specifications can be provided at a low cost.

[0036] Furthermore, for example, if a new locking device 1 is installed using the first base 31 and the second base 32, and later the user requests the addition of the first authentication device 75, either the first base 31 or the second base 32 can be replaced with the third base 33. Since the third base 33 is compatible with at least one of the first base 31 and the second base 32, the third base 33 can be easily installed without modifying the door 2 or the grip 34.

[0037] Furthermore, according to this embodiment, it is possible to design the third base 33, the first base 31, and the second base 32 to have a unified appearance. Therefore, regardless of whether the specification with the first authentication device 75 or the specification without the first authentication device 75 is selected, a lock device 1 with a unified appearance can be provided. In addition, even if either the first base 31 or the second base 32 is replaced with the third base 33, the unified appearance can be maintained.

[0038] Furthermore, according to the lock device 1 of this embodiment, a second authentication device 8 is provided for authenticating the user, and the drive devices 9d and 10d drive the lock according to the authentication result of at least one of the first authentication device 75 and the second authentication device 8. The second authentication device 8 may be provided, for example, on the grip 34, on the first base 31 or the second base 32, or on the door 2. That is, the second authentication device 8 is provided in a standard lock device 1 that uses the first base 31 and the second base 32 (without using the third base 33). In contrast, the first authentication device 75 is added by replacing either the first base 31 or the second base 32 with the third base 33. With this configuration, the security of authentication can be enhanced by using both the first authentication device 75 and the second authentication device 8. In addition, convenience can be enhanced by making it possible to select either the first authentication device 75 or the second authentication device 8. Furthermore, authentication can be performed even if either the first authentication device 75 or the second authentication device 8 is unavailable.

[0039] Furthermore, according to the locking device 1 of this embodiment, the third base 33 is provided with an engaging portion 62 that engages with an engaging portion 45 provided on the grip 34. With this configuration, the grip 34 can be easily attached to and detached from the third base 33.

[0040] Furthermore, according to the locking device 1 of this embodiment, the grip 34 includes a latch lever 42 that actsuates the latch bolt 7a, a pivot shaft 43 that pivotably supports the latch lever 42, and a lever 6 that actsuates the latch lever 42. The lever 6 is equipped with a pin 6a that slides against an elongated hole 44 provided in the latch lever 42, and the pivot shaft 43 and the pin 6a are prevented from coming off by flanges 43F, 6F provided at one end and retaining means 43R, 6R attached to the other end. With this configuration, the latch lever 42 can be realized with a simple structure.

[0041] Furthermore, according to the lock device 1 of this embodiment, the grip 34 is equipped with a connector 46 for connecting the terminal 74 of the first authentication device 75, and the terminal 74 and the connector 46 are facing each other in the direction in which the grip 34 is attached to the third base 33. With this configuration, the electrical connection of the first authentication device 75 can be easily made.

[0042] While the above-described embodiment describes the best mode of the lock device 1 according to the present invention, the present invention is not limited by the description and drawings of this embodiment. For example, a contactless IC card was given as an example of an external authentication medium that communicates with the second authentication device 8, but this could also be an ID key or a mobile terminal such as a smartphone that communicates wirelessly with the second authentication device 8. Furthermore, the components of the present invention described above can be replaced with existing components as appropriate, and various variations including combinations with other existing components are possible, and the above-described embodiment of the present invention does not limit the content of the invention described in the claims.
