  • a space for receiving almost other elements is formed at a faced portion of the upper and lower bodies 12 and 14 (i.e., a lower portion of the upper body 12 and an upper portion of the lower body 14), thereby forming the outer appearance of the clutch assembly 10.
  • the clutch assembly 10 formed by coupling the upper and lower bodies 12 and 14 has a small size, it can be facilely installed at the conventional or other electronic door locking device.
  • the first shaft 20 is disposed to be exposed to the outside through a hole 122 of the upper body 12.
  • the first shaft 20 is connected with an internal handle (not shown) of the door or a shaft of the internal handle and rotated together when the internal handle is rotated.
  • the first shaft 20 is mechanically connected with construction elements for operating a latch (not shown) and thus directly or indirectly drives the latch upon its rotation.
  • One of both ends of the first shaft 20, which is coupled with the shaft connection member 40, is formed into shape of a square pillar (22).
  • the second shaft 30 is disposed in the clutch assembly 10 so as to have the same axial center as the first shaft 20 and also spaced part from the first shaft 20 so as to be not directly connected or contacted with the first shaft 20.
  • the second shaft 30 is connected with an internal handle (not shown) of the door or a shaft of the internal handle and rotated together when the internal handle is rotated.
  • the first shaft 20 is connected with an external handle (not shown) of the door or a shaft of the external handle and rotated together when the external handle is rotated.
  • One end of the second shaft 30 is formed into a square pillar shape so as to be firmly coupled with the external handle and the other end thereof has a first uneven portion 32 so as to be coupled with the shaft connection member 40.
  • the first uneven portion 32 consists of a cross-shaped groove and protrusions formed by the groove.
  • the first and second shafts 20 and 30 are rotatably disposed in the clutch assembly 10.
  • the shaft connection member 40 is disposed between the first and second shafts 20 and 30 so as to be reciprocated between the first and second shafts 20 and 30. More detailedly, the shaft connection member 40 is disposed at a square pillar 22 of the first shaft 20 so as to be movable in an axial direction thereof so that the first and second shafts 20 and 30 are selectively connected with each other and thus the rotation of the second shaft 30 can be transmitted to the first shaft 20.
  • One end of the shaft connection member 40 (which is faced with the first shaft 20) is formed with a square hole 46 having a desired depth and the other end thereof (which is faced with the second shaft 30) is formed with a second uneven portion 42 (a cross-shaped protrusion in case of the embodiment) which is engaged with the first uneven portion 32.
  • a second groove 44 having a desired width is formed at the outer circumference of the shaft connection member 40. And a stepped portion is formed at both side ends of the outer circumference of the shaft connection member 40 by the second groove 44.
  • the shaft connection member 40 is formed to be longer than a spaced distance between the first and second shafts 20 and 30. In other words, the shaft connection member 40 has an enough length to be engaged with the first uneven portion 32 of the second shaft 30 while the shaft connection member 40 is coupled with the first shaft 20.
  • the motor 50 is installed at the lower body 14 so as to generate driving force for driving the shaft connection member 40.
  • the motor 50 is provided with a shaft 52 extended in one direction (i.e., toward the first shaft 20 in case of the embodiment), and the shaft 52 is rotated when the motor 50 is operated.
  • the shaft 52 is formed with a through-hole which is formed to be vertical to a length direction thereof, and a pin 54 is inserted into the through-hole.
  • the pin 54 functions to move a coil spring 60 inserted onto the shaft 52 of the motor 50 (this will be described later).
  • the coil spring 60 is installed at the shaft 52 of the motor 50 and functions to move the driving member 70 in the axial direction thereof when the motor 50 is driven.
  • This function can be achieved by that the pin 54 compresses the coil spring 60 toward one side or the other side thereof according to forward rotation or reverse rotation of the motor 50. Therefore, it is preferable that both ends of the coil spring 60 is closely wound or opened unlike a conventional spring, such that the pin 54 can be moved inside the coil spring 60.
  • the driving member 70 is installed at the shaft 52 of the motor 50 together with the coil spring 60.

  • An opening formed at each end of the driving member 70 has a smaller diameter than a diameter of the coil spring 60 (but the shaft of the motor can be inserted therein), such that the coil spring 60 disposed in the driving member 70 is not separated to the outside.
  • one end of the coil spring 60 is firstly inserted into the opening of the driving member 70 and the coil spring 60 is then rotated continuously (i.e., the coil spring 60 is inserted into the driving member 70 by its own screw motion).
  • the operation member 80 is rotatably disposed at the upper body 12 or lower body 14 and functions to convert a displacement of the driving member 70 into a displacement of the shaft connection member 40.
  • the operation member 80 is provided with an axial portion 82 functioning as a rotational axis, and two pairs of legs 84 and 86 which are symmetrically disposed about the axial portion 82.
  • Each pair of legs 84, 86 are extended to be parallel with each other and inserted into the driving member 70 and the shaft connection member 40.
  • the first pair of legs 84 are inserted into the first groove 72 of the driving member 70 and the second pair of legs 86 are inserted into the second groove 44 of the shaft connection member 40 (referring to Fig. 3 ).
  • the driving member 70 is moved to one side along the shaft 52 of the motor 50, the displacement of the driving member 70 is transmitted to the shaft connection member 40 through the operation member 80 and thus the shaft connection member 40 is reversely moved corresponding to the displacement of the driving member 70 (that is, the operation member 80 functions as a lever).
  • the guide member 90 is disposed in the clutch assembly 10 and functions as a guider which allows the shaft connection member 40 to be stably moved within a preset range and also functions as a boss which supports the axial portion 82 of the operation member 80.
  • the guide member 90 may further include a guide rod 92 which passes through the shaft connection member 40 and the second shaft 30. Meanwhile, the guide member 90 and the guide rod 92 may be omitted or modified depending on the internal structure of the clutch assembly 10.
  • the pin 54 is installed at the shaft 52 of the motor 50.
  • the pin 54 is moved along the spiral body of the coil spring 60 when the motor 50 is driven (actually, the coil spring 60 is moved) and compresses the coil spring 60.
  • the motor 50 is driven clockwise (in an arrow direction of Fig. 4 )
  • the pin 54 is moved along the spiral body of the coil spring 60 and compresses left (in Fig. 5 ) the coil spring 60 (referring to Fig. 5a ).
  • the pin 54 is moved along the spiral body of the coil spring 60 and compresses right the coil spring 60 (referring to Fig. 5b ).
  • the compression of the coil spring 60 causes the driving member 70 to be moved by restoring force of the coil spring 60.
  • the driving member 70 is pushed left by the restoring force of the coil spring 60 (referring to Fig. 5a ).
  • the driving member 70 is pushed right by the restoring force of the coil spring 60 (referring to Fig. 5b ).
  • the first and second shafts 20 and 30 are maintained in the state of being separated from each other.

  • the shaft connection member 40 and the second shaft 30 are normally maintained in the state of being separated from each other.
  • This state is achieved by that the driving member 70 is moved to the motor 50, as shown in Fig. 6 . That is, if the driving member 70 is moved right by the rotation of the motor 50 and the restoring force of the coil spring 60, the shaft connection member 40 is moved left by the counterclockwise rotation of the operation member 80 (in Fig. 6 ) rotated by the rotation of the driving member 70, and thus the shaft connection member 40 and the second shaft 30 are separated from each other.
  • the driving member 70 is moved left by the restoring force of the coil spring 60, and the shaft connection member 40 is moved right by the operation member 80 which is rotated counterclockwise. Then, the second uneven portion 42 of the shaft connection member 40 is engaged with the first uneven portion 32 of the second shaft 30, and the first and second shafts 20 and 30 are connected with each other through the shaft connection member 40, and the internal handle of the door can be rotated by the rotation of the external handle of the door.
  • some of the door handles has an elastic member so as to be returned to its original position when the handles are rotated by the user.
  • a recent handle is formed to be freely rotated (that is, the handle is not returned to its original position after the handle is rotated by the user).
  • the present invention can solve the problem.
  • the driving member 70 and the coil spring 60 are maintained in the state shown by the solid line of Fig. 5a .
  • the driving member 70 is maintained in a state of being not completely moved left, and the coil spring 60 is maintained in a state of being compressed.
  • the door locking device includes an outer body 100, an inner body 200, a striker 300 and a clutch assembly 10.

  • the clutch assembly 10 is disposed in a hole H of the door D and connected with the handle 102 of the outer body 100 and the handle 202 of the inner body 200. As described above, the clutch assembly 10 connected with the two handles 102 and 202 functions to selectively connect or disconnect the hand 102 of the outer body 100 and the handle 202 of the inner body 200 according to an external signal, such that the latch 204 is operated by only the authorized external signal.

  • the first contact member 164 is an elongated shaft-shaped member and functions to connect the shaft 122 of the first handle 120 and the clutch assembly 160.
  • One end of the first contact member 164 has a thick rod shape which is coupled to the shaft 122, and the other end thereof has a cylindrical shape which is inserted into the hole 1626 of the housing 162.
  • the other end of the first contact member 164 has a circular shape in section, of which a diameter is the same as a width of the hole 1626, the first contact member 164 can be rotated while being contacted with the inner wall of the hole 1626. Meanwhile, the other end of the first contact member 164 is formed with a protrusion 1642 for connecting with the second contact member 166.
  • the second contact member 166 is formed with a hexahedral shape which is inserted into the hole 1626 of the housing 162.
  • the second contact member 166 is installed in the hole 1626 of the housing 162 so as to be movable in the length direction of the housing 162.
  • One end of the second contact member 166 is formed with a groove 1662 which is mated with the protrusion 1642 of the first contact member 164, and an insertion hole 1664 in which a protrusion of the press member 168 is inserted is formed in a side surface (a lower side of Fig. 12 ) of the second contact member 166.
  • the second contact member 166 is rotated integrally with the housing 162 and moved forward and backward in the length direction of the housing 162 and also selectively engaged with the first contact member 164.
  • the pair of press members 168 has a curved shape which is bent like a bow.
  • the pair of press members 168 are disposed at the housing 162 so as to be pressed in any radial direction of the housing 162, they are formed into a ring shape (i.e., since the press members 168 is disposed so as to enclose the housing 162, the housing 162 can be pressed by the driving means 154 even though the housing 162 is rotated).
  • Each of the press members 168 has a branched portion 1682 which is protruded from a middle portion of the curved body toward a center portion of a virtual circle formed by the curved body.
  • the branched portion 1682 is fixed to the supporting portion 1622 of the housing 162 by a pin or the like so that the press members 168 can be rotated around a hole formed by the supporting portion 1622. Meanwhile, one of the press members 168 (which is disposed at a lower side of the housing 162) is formed with a protrusion 1684 which is inserted into the insertion hole 1664 of the second contact member 166 through the through-hole 1624 of the housing 162.
  • the protrusion 1684 may be formed by further extending the branched portion 1682.
  • the pair of press members 168 installed on the housing 162 function to move the second contact member 166 according to a rotational direction thereof and thus to connect or disconnect the second contact member 166 with or from the first contact member 164.
  • the elastic member 169 is disposed between the housing 162 and the press member 168 and functions to rotate the pair of press members 168 in one direction (e.g., a direction that the press members 168 are spaced part from each other or a direction that the protrusion 1684 is rotated counterclockwise). Therefore, if external force (generated by the driving means 154) is not applied to the pair of press members 168, the press members 168 are maintained in a state shown in Fig. 11 . In this case, the second contact member 166 is separated from the first contact member by the protrusion 1684 of the press member 168.
  • the connection between the first handle 120 and the second handle 130 is released at normal times so that the latch assembly 142 mechanically connected with the shaft 122 of the first handle 120 is not operated even though rotating the second handle 130 at the outside. That is, the first and second contact members 164 and 166 disposed in the housing 162 of the clutch assembly 160 is maintained in the state shown in Fig. 11 in which they are disconnected from each other.
  • the driving means 154 is operated (i.e., a rod of the driving means 154 is moved down) so as to press at least one of the press members 168.
  • the protrusion 1684 is rotated clockwise (in Fig. 11 ) by the rotation of the press members 168 and thus the first and second contact members 164 and 166 are engaged with each other as shown in Fig. 14 (the detailed structure of each element is shown in Fig. 12 ).
  • the rotational force of second handle 130 can be transmitted to the first handle 120 due to the engagement between the first and second contact members 164 and 166. Therefore, when the second handle 130 is rotated by the user, the latch assembly 142 connected with the first handle 120 is operated and the locking state of the door is released.
  • the latch assembly 142 connected with the first handle 120 is operated by the rotation of the second handle 130 and the locking state of the door is released.
  • the mortise is not needed and the locking device can be facilely installed at the door.
  • the present invention can be installed at any doors having the hole for installing the handle, it is prevented that the door is damaged undesirably when replacing the door locking device.
