The invention of claim 8 is a door locking device which includes a lock switch member adapted to be built in a door of a vehicle, and adapted to rotate between a lock position locking the door and an unlock position unlocking the door when receiving a force from a lock operation portion provided at a vehicle interior side of the door or from an electric drive source built in the door, a key operation transmission member adapted to rotate between a key lock position and a key unlock position when receiving a key operation force relative to a key cylinder provided at the door, the key operation transmission member transmitting the key operation force to the lock switch member so that, in a case where the key operation transmission member rotates to the key lock position, the lock switch member is rotated to the lock position in a cooperating manner, whereas, in a case where the key operation transmission member rotates to the key unlock position, the lock switch member is rotated to the unlock position in the cooperating manner, the key operation transmission member arranged to rotate about a common rotation axis which is shared with the lock switch member, a first movable contact portion provided at one of the lock switch member and the key operation transmission member, and arranged around the common rotation axis, and a second movable contact portion provided at the other one of the lock switch member and the key operation transmission member, and arranged around the common rotation axis in a manner that a predetermined rotation clearance is interposed relative to the first movable contact portion, wherein the first movable contact portion rotates relative to the second movable contact portion in a range of the rotation clearance between the first movable contact portion and the second movable contact portion, and a transmission of a force from the lock switch member to the key operation transmission member is interrupted even in a case where the lock switch member is rotated to any one of the lock position and the unlock position in a state where the key operation transmission member is positioned at a neutral position which is positioned intermediately between the key lock position and the key unlock position, whereas the second movable contact portion rotates relative to the first movable contact portion beyond the rotation clearance between the second movable contact portion and the first movable contact portion and thus the key operation force is transmitted from the key operation transmission member to the lock switch member in a case where the key operation transmission member is rotated from the neutral position to the key lock position and to the key unlock position.
According to the door locking device related to this invention, the key operation transmission member, which transmits the key operation force on the key cylinder to the lock switch member, is arranged so as to rotate about the common rotation axis that is shared with the lock switch member, and therefore a reduction in size of the door locking device is enabled in comparison with a conventional device at which the lock switch member and the key operation transmission member are arranged so as to rotate about different rotation axes from each other. In addition, the first movable contact portions and the second movable contact portions which are for transmitting the force to the key operation transmission member and the lock switch member are arranged around the common rotation axis which is shared with the key operation transmission member and the lock switch member, and thus a rotation space for the first and second movable contact portions fits within a circular-shaped area around the common rotation axis. Also in this respect, the reduction in the size of the door locking device is enabled.
Specifically, for example, a configuration may include the latch unit adapted to be able to keep the door in the state where the door is closed relative to the vehicle, the open link which is adapted to transfer to the unlock position where the engagement relative to the latch unit is possible and to the lock position where the engagement relative to the latch unit is impossible, and is adapted to lock the door at the lock position, whereas the open link is adapted to unlock the door at the unlock position, the active lever defining the lock position and the unlock position of the open link, and the active lever may be, as the above-described lock switch member, connected to the key operation transmission member (the invention of claim 6).
Further, in addition to the latch unit, the open link and the active lever which are described above, the configuration may include the relay lever rotating about the rotation axis which is different from the active lever, and the lever connecting member connecting the active lever and the relay lever to each other so that the active lever and the relay lever are movable in the cooperating manner with each other, and the relay lever may be, as the above-described lock switch member, connected to the key operation transmission member (the invention of claim 4).
Further, in addition to the latch unit, the open link, the active lever and the relay lever which are described above, the configuration may include the long hole provided at one of the active lever and the relay lever, and the pin which is provided at the other one of the active lever and the relay lever, engages with the long hole and enables the active lever and the relay lever to move in the cooperating manner with each other, and the relay lever may be, as the lock switch member, connected to the key operation transmission member (the invention of claim 5).
In addition, according to the configuration of claim 3, the pair of first movable contact portions each arranged at one of the lateral surfaces of each of the pair of the first fan-shaped protruding portions is in surface contact with the pair of second movable contact portions each arranged at one of the lateral surfaces of each of the pair of the second fan-shaped protruding portions in a case where the key operation transmission member is rotated to the key lock position, and the pair of first movable contact portions each arranged at the other one of the lateral surfaces of each of the pair of the first fan-shaped protruding portions is in surface contact with the pair of second movable contact portions each arranged at the other one of the lateral surfaces of each of the pair of the second fan-shaped protruding portions in a case where the key operation transmission member is rotated to the key unlock position. Thus, according to this invention, the pair of first movable contact portions and the pair of second movable contact portions are in surface contact with each other in order to transmit the key operation force from the key operation transmission member to the lock switch member, and therefore a load applied to the first and second movable contact portions is reduced and durability improves compared to a device at which only a single first movable contact portion and a single second movable contact portion are in surface contact with each other or a device at which the first and second movable contact portions are in point-contact or in line-contact with each other.
A first embodiment of this invention will be described hereunder on the basis of
At the first outer surface 11A of the support body 11, a striker receiving groove 12 extending in a horizontal direction is opened. A striker receiving opening 12K, which is at one end of the striker receiving groove 12, is opened at a second outer surface 11B of the support body 11 which is at an opposite side to the first outer surface 11A with respect to the bent portion. Then, the striker receiving groove 12 is exposed outside the door 101 via a cut-out hole 101B (see
The striker 15 as a whole is formed, for example, by bending a wire material having a circular cross section into a gate-shape configuration, and a pair of leg portions of the gate-shape configuration protrudes from the inner surface of the door frame 100W and is arranged in an in-out direction. Then, a latch 13 that will be described later engages with one of the pair of leg portions of the striker 15, the one which is positioned closer to the outside. In
As shown in
In addition, the latch 13 is biased in an unlatch direction (in the clockwise direction in
At the unlatched position, a state is formed in which the first locking tab 13A is evacuated and positioned above the striker receiving groove 12, and the second locking tab 13B is across the striker receiving groove 12, and an opening end of the striker receiving portion 13C faces towards the striker receiving opening 12K of the striker receiving groove 12. Then, the striker 15 entering the striker receiving groove 12 is received in the striker receiving portion 13C, and the striker 15 pushes the second locking tab 13B and thus the latch 13 rotates in a latch direction (in the counter-clockwise direction in
The ratchet 14 is for holding the latch 13 in a state where the latch 13 engages with the striker 15, and the ratchet 14 rotates about a ratchet rotation axis body 14J, which is arranged at the support body 11, at a lower position relative to the striker receiving groove 12, in a same plane as the latch 13. In addition, the ratchet 14 includes a latch rotation restriction piece 14A and a stopper piece 14B which protrude from the ratchet rotation axis body 14J in different directions from each other. Further, the ratchet 14 is biased in the counter-clockwise direction in
In a case where the door 101 is closed from a state in which the door 101 is open, the ratchet 14 engages with the latch 13 in a manner that will be described below. When the door 101 is closed, the second locking tab 13B and the first locking tab 13A of the latch 13 are pushed by the striker 15 to rotate, and push down the latch rotation restriction piece 14A of the ratchet 14 and pass the latch rotation restriction piece 14A of the ratchet 14 sequentially. Then, in a case where the door 101 reaches a position where the door 101 pushes and crushes a sound insulation member between the door 101 and the door frame 100W to a maximum extent, the latch 13 reaches an over stroke position where the second locking tab 13B is slightly away from the latch rotation restriction piece 14A of the ratchet 14, and thereby the ratchet 14 returns to the original position. Then, when the door 101 is pushed back by a resilient force of the sound insulation member, the latch rotation restriction piece 14A of the ratchet 14 impacts against the first locking tab 13A of the latch 13 from an opposite side to the striker receiving portion 13C, and the latch 13 is positioned at a fully-latched position. Thus, a fully-latched state, at which the latch 13 is restricted from rotating in an unlatch direction, is formed and the door 101 is kept in a fully-closed state.
A rotation restriction imposed on the latch 13 by the ratchet 14 can be released by either of an outside door handle 104 provided at a vehicle outside surface of the door 101 as shown in
Specifically, the ratchet rotation axis body 14J is rotatably supported at the support body 11 in a state where the ratchet rotation axis body 14J passes through a base wall 11C (see
The lift lever 16 is provided with a first tilt arm 16A protruding from the ratchet rotation axis body 14J towards a side (hereunder, this will be referred to as “a front side” and an opposite side thereto will be referred to as “a rear side”) of the striker receiving opening 12K of the striker receiving groove 12 (see
An outside open lever rotation axis body 17J is provided at the rear side relative to the ratchet rotation axis body 14J, at a position obliquely below the ratchet rotation axis body 14J so as to be parallel to the ratchet rotation axis body 14J, and an outside open lever 17 is rotatably supported at the outside open lever rotation axis body 17J.
The outside open lever 17 is provided with a support arm 17A protruding from the outside open lever rotation axis body 17J towards the front side and an operation arm 17D procuring from the outside open lever rotation axis body 17J towards the rear side. Then, a rotation range of the outside open lever 17 is restricted by a stopper which is not shown in the drawing, and the outside open lever 17 rotates between a non-operation position shown in
An engagement hole 17B is formed so as to pass through a distal end portion of the support arm 17A in a direction that is parallel to an axial direction of the outside open lever rotation axis body 17J. The engagement hole 17B is formed in a shape that includes a pair of mound-shaped protruding portions 17T, 17T protruding from two positions which are at an inner circumferential surface of a circular-shaped hole and are apart from each other by 180 degrees, and the mound-shaped protruding portions 17T, 17T protrude towards a side at which the mound-shaped protruding portions 17T, 17T are close to each other.
At a lower edge portion of a distal end of the support arm 17A, a pressure receiving piece 17C is protrudingly formed by being bent in the axial direction of the outside open lever rotation axis body 17J, Then, in a case where the inside door handle 105 is operated, an inside open lever 20, which will be described later, comes in contact with the pressure receiving piece 17C from below and thus rotates the outside open lever 17 from the non-operation position to the operation position.
In addition, at an upper edge portion of a distal end of the operation arm 17D, a rod engagement piece 17E is protrudingly formed by being bent in the axial direction of the outside open lever rotation axis body 17J. Then, a rod, which is connected to the rod engagement piece 17E and is not shown in the drawing, is connected to the outside door handle 104, and the rod engagement piece 17E is pushed downwardly in a case where the outside door handle 104 is operated, and thus the outside open lever 17 rotates from the non-operation position to the operation position.
As shown in
At an upper edge portion of the open link 19, a push-up protruding piece 19C is protrudingly formed by being bent in the axial direction of the outside open lever rotation axis body 17J. Then, in a case where the open link 19 is positioned at the unlock position, the push-up protruding piece 19C is positioned below the distal end contact portion 16B of the lift lever 16 as shown in
On the other hand, in a case where the open link 19 is positioned at the lock position, the push-up protruding piece 19C is dislocated from the distal end contact portion 16B of the lift lever 16 toward the ratchet rotation axis body 14J as shown in
From a rear edge portion of an upper end portion of the open link 19, a rotation restriction protruding portion 19D is bent in the axial direction of the outside open lever rotation axis body 17J and the rotation restriction protruding portion 19D protrudes upwardly from the push-up protruding piece 19C. In addition, an upper end portion of the rotation restriction protruding portion 19D is bent toward the front side so as to form a mount configuration. Then, in a case where the outside open lever 17 rotates to the operation position when the open link 19 is at the unlock position, the rotation restriction protruding portion 19D is lifted up while being guided by an unlock retaining protruding portion which is not shown in the drawing. That is, the rotation restriction protruding portion 19D and the unlock retaining protruding portion are for holding the open link 19, which is away from an active operation arm 25C of an active lever 25, in an unlocked state.
A lower end arm 19F protrudes forward from a position closer to a lower end of the open link 19, and a lock-release piece 19B is bent from a lower edge portion of the lower end arm 19F in the axial direction of the outside open lever rotation axis body 17J so as to protrude forward. Then, the open link 19 is switched from the unlock position to the lock position in a case where the lock-release piece 19B is pushed upwardly by the active lever 25 which will be described later.
From a front edge portion of an intermediate portion of the open link 19 in the up/down direction, a restriction receiving portion 19E is bent in the axial direction of the outside open lever rotation axis body 17J. The restriction receiving portion 19E will be described together with the active lever 25 which will be described later.
In a case where the door 101 is closed when the open link 19 is positioned at the lock position, the contacting protruding piece 16D of the lift lever 16, which rotates together with the ratchet 14 pushes the open link 19 from rearward so that the open link 19 is moved to the unlock position in a closing process of the door 101. That is, the door locking device 10 of this invention is provided with a cancellation function which releases the locked state in a case where the door 101 is closed when the locked state is formed.
The latch 13, the ratchet 14, the lift lever 16, the outside open lever 17, which are described above, are supported at the support body 11 so as to rotate about a rotation center axis facing a direction that is orthogonal to the first outer surface 11A of the support body 11 (see
The inside open lever 20 rotates about an inside open lever rotation axis body 20J arranged at a position closer to a lower end of a right side portion of the support body 11 when facing the support body 11. In addition, a part of the inside open lever 20 extends from the inside open lever rotation axis body 20J toward a central side in a lateral direction of the support body 11, and a distal end portion thereof is bent in the axial direction of the inside open lever rotation axis body 20J and forms a push-up contact portion 20B. In addition, another part of the inside open lever 20 protrudes toward downward and a distal end portion thereof forms a wire locking piece 20A. Then, the inside door handle 105 is connected to the wire locking piece 20A via a wire W1 (see
In addition, because the wire W1 is assembled on the inside open lever 20, the inside open lever 20 is held in a non-operation position where the wire locking piece 20A is in contact with a wall surface of the support body 11. Then, in a case where the inside door handle 105 is operated, the inside open lever 20 is pulled via the wire W1 towards the left side in
The active lever 25 for switching the open link 19 from the unlock position to the lock position rotates about an active lever rotation axis body 25J which is arranged at the support body 11, at an opposite side position that is opposite to the inside open lever rotation axis body 20J, with the open link 19 interposed between the active lever rotation axis body 25J and the inside open lever rotation axis body 20J. In addition, the active lever 25 is provided with a first fan-shaped protruding piece 25A jutting out upwardly from the active lever rotation axis body 25J, a second fan-shaped protruding piece 25D formed in a fan shape and jutting out obliquely left downward from the active lever rotation axis body 25J, and the active operation arm 25C protruding from the active lever rotation axis body 25J toward an obliquely right side.
As shown in
As shown in
A lock retaining arm 25B protrudes from one side edge portion, which is at a side closer to the active operation arm 25C, of the first fan-shaped protruding piece 25A. A part of the lock retaining arm 25B faces the restriction receiving portion 19E of the open link 19, and a lock retention protruding portion 25T (see
As shown in
The active lever 25 can be switched to the unlock position and to the lock position by a centralized lock operation switch 107 (see
At a facing surface of the worm wheel 24 which faces the first fan-shaped protruding piece 25A, a pair of rotation-pressing-protruding portions 24A, 24A is protrudingly formed at two positions which interpose the wheel rotation axis body 24J therebetween. On the other hand, a side of the first fan-shaped protruding piece 25A, the side which is away from the active lever rotation axis body 25J than the circular arc hole 25S, is formed to have a thickness which increases towards the worm wheel 24, and an engagement groove 25M is formed at a center of the thickness-increased portion in a circumferential direction. Then, the worm wheel 24 is normally maintained at a position where the rotation-pressing-protruding portions 24A, 24A are arranged along the circumferential direction of the circular arc hole 25S, and the worm wheel 24 rotates in the counter-clockwise direction in
On the other hand, in a case where an unlock operation of the centralized lock operation switch 107 and/or the wireless key 108 is performed, the worm wheel 24 rotates in the clockwise direction in
As shown in
The active lever 25 can be switched to the unlock position and to the lock position also by performing an operation by inserting a key 103 (sec
The key operation transmission link 32 corresponds to “a key operation transmission member” related to this invention, and includes a configuration where a torque transmission arm 32B projects laterally from a rear end of a torque transmission shaft 32A extending in parallel to the inside open lever rotation axis body 20J. Then, the torque transmission shaft 32A is inserted into a support cylinder 11T from behind and is assembled thereon. The support cylinder 11T projects from a reverse surface of the support body 11, which is an opposite surface to a front surface on which the active lever 25 and the like are assembled.
In addition, a stopper 11S protrudes from a rear end surface of the support cylinder 11T, from two positions that are apart from each other by 180 degrees. On the other hand, as shown in
As illustrated in
At an outer circumferential surface of a base end portion of the distal end shaft 32F, a pair of second fan-shaped protruding portions 32C, 32C is provided at two positions that are away from each other by 180 degrees in the circumferential direction, and the pair of second fan-shaped protruding portions 32C, 32C and the above-described pair of lock protrusions 32D, 32D are arranged so that a phase is shifted by 90 degrees. In this embodiment, both lateral surfaces of each of the second fan-shaped protruding portions 32C, 32C correspond to a pair of second movable contact portions 32T, 32T related to this invention, and are so configured that a line, on which the both lateral surfaces of each of the second fan-shaped protruding portions 32C intersect with each other in a case where the both lateral surfaces are extended, coincides with a center line of the torque transmission shaft 32A. In addition, outer circumferential surfaces of the second fan-shaped protruding portions 32C, 32C are flush with an outer circumferential surface of the torque transmission shaft 32A. Then, in a state where the torque transmission shaft 32A is inserted in the support cylinder 11T up to an innermost portion of the support cylinder 11T, a distal end-side of the key operation transmission link 32 relative to the second fan-shaped protruding portions 32C, 32C protrudes towards the front surface side of the support body 11, and the relay lever 31 shown in a lower portion of
The relay lever 31 corresponds to “a lock switch member” related to this invention and is formed in a configuration where a lever main portion 31F projects laterally from an outer circumferential surface of a disc portion 31E which is connected to the key operation transmission link 32. At a center of the disc portion 31E, a center hole 31C is formed to pass through the disc portion 31E. In addition, at one end surface of the disc portion 31E, a circular-shaped recessed portion 31B of which inner diameter is larger than the center hole 31C is formed to be recessed, and a pair of first fan-shaped protruding portions 31A, 31A is provided at an inner circumferential surface of the circular-shaped recessed portion 31B, at two positions that are away from each other by 180 degrees. An inner circumferential surface of each of the first fan-shaped protruding portions 31A is flush with an inner circumferential surface of the center hole 31C. In addition, both lateral surfaces of each of the first fan-shaped protruding portions 31A correspond to a pair of first movable contact portions 31T, 31T related to this invention, and are so configured that a line, on which the both lateral surfaces of the first fan-shaped protruding portions 31A intersect with each other in a case where the both lateral surfaces are extended, coincides with the center line of the torque transmission shaft 32A. Then, the distal end shaft 32F passes through the center hole 31C and the lock protrusions 32D are locked at a front-side end surface of the disc portion 31E, and the second fan-shaped protruding portions 32C and the first fan-shaped protruding portions 31A are assembled on each other in a state where the second fan-shaped protruding portions 32C and the first fan-shaped protruding portions 31A are arranged alternately with each other around the distal end shaft 32F as shown in
The relay lever 31 is connected to the active lever 25 by means of the lever connecting member 30. Specifically, one end portion of the lever connecting member 30 is rotatably connected to a connecting shaft body 30K provided at a distal end of the lever main portion 31F of the relay lever 31, whereas the other end portion of the lever connecting member 30 is rotatably connected to a connecting shaft body 30J provided at the second fan-shaped protruding piece 25D of the active lever 25. Thus, the relay lever 31 rotates in a cooperating manner with the active lever 25, and the relay lever 31 is positioned at the lock position in a case where the active lever 25 is positioned at the lock position as shown in
On the other hand, the above-described key operation transmission link 32 rotates in a cooperating manner with the key cylinder 102, the key operation transmission link 32 is positioned at the key lock position in a case where the key operation is performed and the key cylinder 102 is at the key lock position, and the key operation transmission link 32 is positioned at the key unlock position in a case where the key operation is performed and the key cylinder 102 is at the key unlock position. In addition, the key cylinder 102 is normally positioned at a neutral position which is located intermediately between the key lock position and the key unlock position, and in cooperation with this, also the key operation transmission link 32 is normally positioned at a neutral position which is positioned intermediately between the key lock position and the key unlock position.
Then, when the relay lever 31 is positioned at the unlock position together with the active lever 25 in a state where the key operation transmission link 32 is positioned at the neutral position, a relatively large rotation clearance SP is formed between each of the first fan-shaped protruding portions 31A and the second fan-shaped protruding portion 32C which is adjacent to the first fan-shaped protruding portion 31A in the counter-clockwise direction as shown in
On the other hand, when the key operation transmission link 32 is rotated from the neutral position to the key lock position in a state where the relay lever 31 is positioned at the unlock position together with the active lever 25 as shown in
Thus, according to the door locking device 10 of this embodiment, the key operation transmission link 32, which transmits the key operation force applied relative to the key cylinder 102 to the relay lever 31 serving as “the lock switch member” related to this invention, is arranged so as to rotate about a common rotation axis J1 (see
Further, according to the door locking device 10 of this embodiment, in order to transmit the force of the key operation from the key operation transmission link 32 to the relay lever 31, the pair of first movable contact portions 31T, 31T and the pair of second movable contact portions 32T, 32T are in surface-contact with each other, and therefore a load applied to the first and second movable contact portions 31T, 32T is reduced and durability improves compared to a device at which only a single first movable contact portion 31T and a single second movable contact portion 32T are in surface-contact with each other, and compared to a device at which the first and second movable contact portions 31T, 32T are in point-contact or in line-contact with each other.

In addition, the door locking device 10 of the first embodiment is so configured that in a case where the key operation transmission link 32 rotates in the clockwise direction, the active lever 25 also rotates in the clockwise direction, and in a case where the key operation transmission link 32 rotates in the counter-clockwise direction, the active lever 25 also rotates in the counter-clockwise direction, however, according to the door locking device 10W of this embodiment, in a case where the key operation transmission link 32 rotates in the clockwise direction, the active lever 25 rotates in the counter-clockwise direction as indicated in a change from
A door locking device 10V of this embodiment is shown in
According to the configuration of the door locking device 10 of the first embodiment, as shown in
Specifically, by bending a front end portion of an outside open lever 17V of this embodiment at right angles in the axial direction of the outside open lever rotation axis body 17J, a front end bent piece 17F is formed at the outside open lever 17V, and an engagement protruding piece 17K is protrudingly formed at the front end bent piece 17F so as to protrude in a direction away from the outside open lever rotation axis body 17J. On the other hand, an engagement hole 19K including an identical configuration to that of the engagement hole 17B (see
The open link 19V is provided with a link main portion 19L extending upwardly from the engagement protruding piece 17K and is provided with a connection piece 19P projecting from the link main portion 19L laterally towards the left side in
As shown in
A lift lever 16V of this embodiment is provided with a distal end contact portion 16B in a manner that the distal end contact portion 16B is positioned directly above the link main portion 19L of the open link 19V at the unlock position. In addition, a cancel link 36 is rotatably supported by the lock link rotation axis body 35J together with the lock link 35. The cancel link 36 is, as shown in
Then, when the door is closed in a state where the open link 19V is positioned at the lock position, in the closing process of the door, the driven lever 36B of the cancel link 36 is pushed up by the lift lever 16V rotating together with the ratchet 14 (see
The active lever 25V of this embodiment is provided with a positioning connecting arm 25H projecting obliquely upwardly, and the positioning support column 25G is protrudingly formed at a reverse surface of the positioning connecting arm 25R as shown in
As shown in
In addition, a support portion 11G protrudes from an edge portion at a front side of the main body rear surface protruding wall 11M, and a support ring 11N formed in a cylindrical shape is formed at the support portion 11G. Then, one end of a rotation cylinder axis 25Y, which is formed in a cylindrical shape and is provided at the active lever 25V, is inserted inside the support ring 11N and is rotatably supported thereat.
In addition, a letter-U-groove 11K is formed at a portion of the fitting wall 11J, the portion which intersects with a central axis of the support ring 11N in a case where the central axis is extended. Then, as shown in
In this embodiment, the above-described active lever 25V corresponds to “the lock switch member” related to this invention, and the key operation transmission link 32V is connected to the active lever 25V. For the connection thereof, as shown in
With the above-described configuration, in a similar manner to the door locking device 10 of the first embodiment, the door locking device 10V of this embodiment is also be able to transmit the force of the key operation, which is operated relative to the key cylinder, from the key operation transmission link 32V serving as “the key operation transmission member” to the active lever 25V serving as “the lock switch member”. Then, because the active lever 25V and the key operation transmission link 32V rotate about a common rotation axis J2 (see
This invention is not limited to the above-explained embodiments, and this invention may be modified variously within a scope without departing from a summary and may be implemented.
