Abstract
Title of Invention Automobile Door Locking Mechanism Abstract of Disclosure An automobile door locking mechanism incorporated with a child lock device which is connected to an actuator lever of the mechanism through idle means and operable to keep the locking mechanism in a locking condition even when a locking knob is released and a door handle or button is manipulated and which allows the door or button to move idly.
Description
- l~Z8~94 ~ is invention rel2tes to an automobile door lockinc, ~ec..a~lsms, and more particularly a child loc'~ device thereof.
There is provided to an interior part of an automobile door a locking knob which does not allow the door to be opened by the manipulation of an interior door handle when it is pressed to a locking position.
However, children play with the locking ~nob, resulting in releasing its locking, and in addition the~ sometimes pull the interior door handle. This means that the locking knob is not absolutely safe for securing the locking of door, 1Q
when children are involved. In order to prevent the above, a device which is commonly called as a child lock device is known. When the automobile door locking mechanisms is incor-porated with such chilid lock device, they can't be unlocked even when the locking knob is played by children and released.
This invention employs structures common to conventional child locking device, while it is characterized in the pro-vision of connector means wi,th,an idle device which are located between the interior door handle and an open or actuator plate.
To the automobile body there is provided an engaging part 2C
which is called as a striker, while to the door there is pro-vided a latch which meshes and engages with the said striker.
Said latch rotates when the door is closed and the striker ensages with the latch. As the latch which has engaged with the striker and has rotated is kept at its position by a ratchet, the door is ke~t locked. ~en a button fitted to the door handle or handle itself is actuated, the open or actuator lever is rotated to release the engagement o~ ratch,et with the latch and to allow the door open. However, when the locking mecha-nis~ is locked by the operation of a key or locking knob, the
There is provided to an interior part of an automobile door a locking knob which does not allow the door to be opened by the manipulation of an interior door handle when it is pressed to a locking position.
However, children play with the locking ~nob, resulting in releasing its locking, and in addition the~ sometimes pull the interior door handle. This means that the locking knob is not absolutely safe for securing the locking of door, 1Q
when children are involved. In order to prevent the above, a device which is commonly called as a child lock device is known. When the automobile door locking mechanisms is incor-porated with such chilid lock device, they can't be unlocked even when the locking knob is played by children and released.
This invention employs structures common to conventional child locking device, while it is characterized in the pro-vision of connector means wi,th,an idle device which are located between the interior door handle and an open or actuator plate.
To the automobile body there is provided an engaging part 2C
which is called as a striker, while to the door there is pro-vided a latch which meshes and engages with the said striker.
Said latch rotates when the door is closed and the striker ensages with the latch. As the latch which has engaged with the striker and has rotated is kept at its position by a ratchet, the door is ke~t locked. ~en a button fitted to the door handle or handle itself is actuated, the open or actuator lever is rotated to release the engagement o~ ratch,et with the latch and to allow the door open. However, when the locking mecha-nis~ is locked by the operation of a key or locking knob, the
- 2 - ~ ~
llZ8{?94 door cannot be opened by pressing the button or the door handle. This is because when the button or handle is operated, the actuator lever can still move, but the rat-chet is not released from the latch on account of the dis-engagement of the actuator lever from the ratchet. Such a mechanism which makes the ratchet immovable even when the open lever is operated is called as idle mechanism in this specification. This idle mechanism is effective to prevent breakage of the locking mechanisms. If the locking mecha-nism is made with such a construction that when it is loc-ked, its handle or button remains immovable, excessive force applied to the button or handle by a passenger would break the locking mechanism.
This invention is, therefore, to provide an auto-mobile door locking mechanism incorporating a child lock device which is connected to an actuator lever of the loc-king mechanism through an idle means and is operable to keep the locking mechanism in a locking condition even when a locking knob is released and a door handle or button is manipulated and which allows the door handle or button to to move idly.
The invention seeks to provide a child lock de-vice which has a lesser number of parts than conventional devices of the kind.
According to the invention there is provided an automobile door locking mechanism comprising a latch rota-table upon engagement with a striker, a ratchet for preven-ting the rotation of the latch in the direction for relea-sing its engagement with the striker, an actuator plate for releasing the engagement of the ratchet with the latch, connecting means for effecting and releasing the engagement of the actuator plate with the ratchet, and a rotary lever operable to actuate the actuator plate in response to 1128~94 operation of an interior door handle, to which another lever is pivotally fitted to a shaft which pivotally loca-tes the rotary lever, one of said levers being formed with a slot opening which extends radially with respect to the shaft and the other being formed with a slot opening having an idle opening which extends circumferentially with res-pect to the shaft, and a connector means having a part `-which passes through the slot openings at a right angle to the plane of rotation of the levers, said connector means being connected to a child lock change lever so as to slidingly change its location within the slot openings and said another lever being connected to the interior door handle, whereby to determine whether actuation of the ac-tuator plate is possible in response to operation of said handle.

Constructions of the locking apparatus in accordance with this invention are explained in the fol~owin~ with referance to the accompanying drawing. 10 A metallic base plate 1 which is fixed to an automobile door and by means of which various component parts of the locking apparatus are assembled at their places, has a slot opening 3.
This opening slidably engages with a striker 2 which is fixedly fitted to the automobile body. A latch 5 which is pivotally fitted to the base plate 1 by an axis 4 l`aces, at its part, to the slot opening, as best shown in ~ig. 2. Said latch has at its circumferential part a should~r 6 which is engageable with a pawl 8 of a ratchet 7 so at to prevent the disengagement of the latch from the striker. Said ratchet 7 is pivotally fitted 20 to the b~se plate 1 by an axis 9 which fixes also an actuator plate 10 pivotally to the base plate. This actuator plate has an opening 11. To this openin~ and at its part which is remote from the axis 9, there is provided an abutment 12 so as to make said openin~ in the rotary direction of the plate 10 have a marrow width T, and at its part adjacent to the axis 9, a~ idle openin6 13. The ratchet 7 and actuator plate 10 are pivoted to the com on axis 9 so as to be one above another, and~the part of ratchet which faces to the opening 11, has a slot 14 which extends in a radial direction of the axis 9. A connecting ~lZ8Q94 rod 15 which projects at a right angle to the slot 14 and open-ing 11, is inserteàly and movably fitted to them. Said rod is changeable of its location to positions a and b (~ig. 2), when a locking lever 16 is actuated.
The operative relation of the connecting rod 15 with the locking lever 16 is illustrated in ~ig. 3 in which the locking lever 16 is pivotally fitted to the base plate by an axis 17 and rotatable to directions W to assume a location of solid lines or another location of dotted lines, when actuated by pressing or pulling a locking knob which is provided to the 10 inside of automobile door or by operating a key. A rod 18 which engages at its end the locking lever 16 and which is fitted at its another end to the connectin~ rod 15, connects them.
With reference to Figs. 1 and 2, the actuator plate 10 is connected at its left end L to an exterior door handle by suitabe connecting means, while its right end R engages a rotary lever 19 which is operative by an interior door handle. Const-ructions of the rotary lever 19 are illustrated in detail in Figs. 4A and 4B. The central portion of rotary lever 19 is pivotally fitted to the base plate 10 by an axis 20, and its 20 lower end 21 engages with the right end R of the actuator plate 10 and its upper part has a slot 22 which extends radia-lly to the axis 20~ A lever 23 is also pivotally fitted to the axis 20 so ;dS to be one over another. To a ?art of the lever 23 which lies over the rotary lever 19, there is pro~ided an elon~ated slot 24 which is corresponsent to the slot 23. A
half portion of said slot 24 which locates adjacent to the axis 20 projects laterally and froms an idle siot 25. Numeral 26 indicates a connecting pin which projects at a right an~le fro~
the to? end of an arm 34 and which engages both the slots 22 A: ) ~lZ8~94 anà 2L~. 'he lower end of the arm 34 is connected to a child 10CK change lever 27 (~ig. 5). When the said lever 27 is opera-ted by a àri~er and rotated to the direction P, the pin 26 slidingly moves between the usper ends and lower ends of the slots 22, 24.
The interior door handle is connected, through rod means, not ~o the rotary lever 19, but to an opening 28 of the lever 23.
In ~ig. 6, fixtures of the child lock change lever 27 are shown. Said lever 27 is made of plastics having slight 10 resiliency, and to the side of its rotary end 30, there is formed a projection 29 which faces to the metallic base plate.
The projection 29 is integral with the lever 27,-anà according, is also of plastics. ~he lever 27 is pivotally fitted to the base plate 1 by a pin 31 which passes through a boss 33. ~he projection 29 projects from the lever 27 slightly larger than the boss 33. ~his makes the rotary end 30 to flex resiliently against recesses 32. Said recesses are two as shown in ~ig. 7, and are located with a distance therebetween. In Fig. 8, there are shown the connectin~ pin 26, the arm 34, and a projec- 20 tion 35 which engages with the child lock chan~e lever 27.
They are all integral and made of plastics. To the both sides of head of the proJection 35, there are formed extensions 36, 36 which extend in a longitudinal direction of the arm 34. A~d, to another rotary piece 37, there is formed a slot 37'. With these structures, when the arm 34 and the child lock change lever 27 are brou~ht near, the extensions 36 are insertedly fitted to the slot 37', and the arm 34 is rotated to the d}rection S, ~-they are firmly engageà each other ar.d would not be released.
~his locking apparatus operates as fo~low:
~lZ8Q9~ . -~ en a child accom~znied b~ a driver rides in a vehicle and the door is closed, the latch 5 of lock device comes to the engagement with the striker 2. As shown in ~ig. 2, the latch 5 rotates about the axis 4, and the pawl 8 of ratchet 7 engages with the shoulder 6 of latch 5 for preventing the reversal rotation of latch 5. On the condition shown by ~
2j when the actuator plate 10 is rotated counter-clockwese by the operation of exterior or interior door handle, the abut-ment 12 presses the connecting rod 15 upwardly, resulting in the pressing of inner wall of the slot 14 and the counter- 10 clockwise rotation of ratchet 7, whereby the pawl 8 is released from the shoulder 6 and the door opens. However, when a seal or locking knob provided interiorly to the door is pressed, the locking lever 16 changes its location from the solid lined position to the dotted lined position as illustrated in Fig. 3, whereby the rod 18 is moved, resulting in changing the location of connecting rod 15 from the position a to the position b.
Under this condition, the counter-clockwise rotation of actua-tor plate 10 by the operation of a door handle does not produce any movement of the connectin~ rod 15 and keep it idle, because 20 said rod is in the idle opening 13. Accordingly ratchet 7 does not move and keeps the device in the locking condition.
Under this condition where the connecting rod in at the position b, when the child lock change lever 27 is rotated cou~ter-cloc~wise as shown in Flg. 5, the arm 34 moves down-wardly, and the connecting pin which is provided to the upper end of said arm 34 moves also downwardly so as to be at a posi-tion within the idle slot 25 of the elongated slot 24 of the lever 23, whereby even when the lever 23 is rotated to the direction S by the operation of interior door handle, it does ~28Q94 not engage with ~he connec' ng rod 15 and the rotary lever 19 does not move. This results that even if a child pulls the seal knob and operates the interior door handle, the door shall never be open (or the door is child locked). In this inven tion, as the child lock change lever 27 is made o~ plastics which have slight resilienc~, and as the rotary end 30 of lever 2~ engages at its projection 29 with the base p~ate 1 flexedly by said projection, the driver can o~erate said lever with certain feeling. In addition, as the lever 27 is made of plas-tics and fitted to the base plate flexedly, the employment of 10 spring washers is eliminated.
As stated above, the child locking mechanisms of this invention employ the lever 23 provided with the idle slot.
This enables that even when the interior door handle is pulled and when the door is child locked, the handle keeps its actuation mechanisms idle without giving u~natural force to them. Also as stated above, the lever 27 of child locking mechanisms is made of plastics, as a whle, resulting in the elimination of spring washers and in making it easy to make. As the connec-ting pin 26, arm 34, pro~ection 35 and extensions 36, 36 are 20 integrally made of plastics, their manuacture is easy.
In addition, as the projection 32 of the plastic lever 27 resiliently and pressedly engases with either one of recesses 32, and accordingly it can assu~e its selecteà position by itself, the provision of over-centering spring to the base plate is also eliminated.
llZ8{?94 door cannot be opened by pressing the button or the door handle. This is because when the button or handle is operated, the actuator lever can still move, but the rat-chet is not released from the latch on account of the dis-engagement of the actuator lever from the ratchet. Such a mechanism which makes the ratchet immovable even when the open lever is operated is called as idle mechanism in this specification. This idle mechanism is effective to prevent breakage of the locking mechanisms. If the locking mecha-nism is made with such a construction that when it is loc-ked, its handle or button remains immovable, excessive force applied to the button or handle by a passenger would break the locking mechanism.
This invention is, therefore, to provide an auto-mobile door locking mechanism incorporating a child lock device which is connected to an actuator lever of the loc-king mechanism through an idle means and is operable to keep the locking mechanism in a locking condition even when a locking knob is released and a door handle or button is manipulated and which allows the door handle or button to to move idly.
The invention seeks to provide a child lock de-vice which has a lesser number of parts than conventional devices of the kind.
According to the invention there is provided an automobile door locking mechanism comprising a latch rota-table upon engagement with a striker, a ratchet for preven-ting the rotation of the latch in the direction for relea-sing its engagement with the striker, an actuator plate for releasing the engagement of the ratchet with the latch, connecting means for effecting and releasing the engagement of the actuator plate with the ratchet, and a rotary lever operable to actuate the actuator plate in response to 1128~94 operation of an interior door handle, to which another lever is pivotally fitted to a shaft which pivotally loca-tes the rotary lever, one of said levers being formed with a slot opening which extends radially with respect to the shaft and the other being formed with a slot opening having an idle opening which extends circumferentially with res-pect to the shaft, and a connector means having a part `-which passes through the slot openings at a right angle to the plane of rotation of the levers, said connector means being connected to a child lock change lever so as to slidingly change its location within the slot openings and said another lever being connected to the interior door handle, whereby to determine whether actuation of the ac-tuator plate is possible in response to operation of said handle.

Constructions of the locking apparatus in accordance with this invention are explained in the fol~owin~ with referance to the accompanying drawing. 10 A metallic base plate 1 which is fixed to an automobile door and by means of which various component parts of the locking apparatus are assembled at their places, has a slot opening 3.
This opening slidably engages with a striker 2 which is fixedly fitted to the automobile body. A latch 5 which is pivotally fitted to the base plate 1 by an axis 4 l`aces, at its part, to the slot opening, as best shown in ~ig. 2. Said latch has at its circumferential part a should~r 6 which is engageable with a pawl 8 of a ratchet 7 so at to prevent the disengagement of the latch from the striker. Said ratchet 7 is pivotally fitted 20 to the b~se plate 1 by an axis 9 which fixes also an actuator plate 10 pivotally to the base plate. This actuator plate has an opening 11. To this openin~ and at its part which is remote from the axis 9, there is provided an abutment 12 so as to make said openin~ in the rotary direction of the plate 10 have a marrow width T, and at its part adjacent to the axis 9, a~ idle openin6 13. The ratchet 7 and actuator plate 10 are pivoted to the com on axis 9 so as to be one above another, and~the part of ratchet which faces to the opening 11, has a slot 14 which extends in a radial direction of the axis 9. A connecting ~lZ8Q94 rod 15 which projects at a right angle to the slot 14 and open-ing 11, is inserteàly and movably fitted to them. Said rod is changeable of its location to positions a and b (~ig. 2), when a locking lever 16 is actuated.
The operative relation of the connecting rod 15 with the locking lever 16 is illustrated in ~ig. 3 in which the locking lever 16 is pivotally fitted to the base plate by an axis 17 and rotatable to directions W to assume a location of solid lines or another location of dotted lines, when actuated by pressing or pulling a locking knob which is provided to the 10 inside of automobile door or by operating a key. A rod 18 which engages at its end the locking lever 16 and which is fitted at its another end to the connectin~ rod 15, connects them.
With reference to Figs. 1 and 2, the actuator plate 10 is connected at its left end L to an exterior door handle by suitabe connecting means, while its right end R engages a rotary lever 19 which is operative by an interior door handle. Const-ructions of the rotary lever 19 are illustrated in detail in Figs. 4A and 4B. The central portion of rotary lever 19 is pivotally fitted to the base plate 10 by an axis 20, and its 20 lower end 21 engages with the right end R of the actuator plate 10 and its upper part has a slot 22 which extends radia-lly to the axis 20~ A lever 23 is also pivotally fitted to the axis 20 so ;dS to be one over another. To a ?art of the lever 23 which lies over the rotary lever 19, there is pro~ided an elon~ated slot 24 which is corresponsent to the slot 23. A
half portion of said slot 24 which locates adjacent to the axis 20 projects laterally and froms an idle siot 25. Numeral 26 indicates a connecting pin which projects at a right an~le fro~
the to? end of an arm 34 and which engages both the slots 22 A: ) ~lZ8~94 anà 2L~. 'he lower end of the arm 34 is connected to a child 10CK change lever 27 (~ig. 5). When the said lever 27 is opera-ted by a àri~er and rotated to the direction P, the pin 26 slidingly moves between the usper ends and lower ends of the slots 22, 24.
The interior door handle is connected, through rod means, not ~o the rotary lever 19, but to an opening 28 of the lever 23.
In ~ig. 6, fixtures of the child lock change lever 27 are shown. Said lever 27 is made of plastics having slight 10 resiliency, and to the side of its rotary end 30, there is formed a projection 29 which faces to the metallic base plate.
The projection 29 is integral with the lever 27,-anà according, is also of plastics. ~he lever 27 is pivotally fitted to the base plate 1 by a pin 31 which passes through a boss 33. ~he projection 29 projects from the lever 27 slightly larger than the boss 33. ~his makes the rotary end 30 to flex resiliently against recesses 32.

In Fig. 8, there are shown the connectin~ pin 26, the arm 34, and a projec- 20 tion 35 which engages with the child lock chan~e lever 27.
They are all integral and made of plastics. To the both sides of head of the proJection 35, there are formed extensions 36, 36 which extend in a longitudinal direction of the arm 34. A~d, to another rotary piece 37, there is formed a slot 37'. With these structures, when the arm 34 and the child lock change lever 27 are brou~ht near, the extensions 36 are insertedly fitted to the slot 37', and the arm 34 is rotated to the d}rection S, ~-they are firmly engageà each other ar.d would not be released.
~his locking apparatus operates as fo~low:

As shown in ~ig. 2, the latch 5 rotates about the axis 4, and the pawl 8 of ratchet 7 engages with the shoulder 6 of latch 5 for preventing the reversal rotation of latch 5. On the condition shown by ~
2j when the actuator plate 10 is rotated counter-clockwese by the operation of exterior or interior door handle, the abut-ment 12 presses the connecting rod 15 upwardly, resulting in the pressing of inner wall of the slot 14 and the counter- 10 clockwise rotation of ratchet 7, whereby the pawl 8 is released from the shoulder 6 and the door opens. However, when a seal or locking knob provided interiorly to the door is pressed, the locking lever 16 changes its location from the solid lined position to the dotted lined position as illustrated in Fig. 3, whereby the rod 18 is moved, resulting in changing the location of connecting rod 15 from the position a to the position b.
Under this condition, the counter-clockwise rotation of actua-tor plate 10 by the operation of a door handle does not produce any movement of the connectin~ rod 15 and keep it idle, because 20 said rod is in the idle opening 13. Accordingly ratchet 7 does not move and keeps the device in the locking condition.
Under this condition where the connecting rod in at the position b, when the child lock change lever 27 is rotated cou~ter-cloc~wise as shown in Flg. 5, the arm 34 moves down-wardly, and the connecting pin which is provided to the upper end of said arm 34 moves also downwardly so as to be at a posi-tion within the idle slot 25 of the elongated slot 24 of the lever 23, whereby even when the lever 23 is rotated to the direction S by the operation of interior door handle, it does ~28Q94 not engage with ~he connec' ng rod 15 and the rotary lever 19 does not move. This results that even if a child pulls the seal knob and operates the interior door handle, the door shall never be open (or the door is child locked). In this inven tion, as the child lock change lever 27 is made o~ plastics which have slight resilienc~, and as the rotary end 30 of lever 2~ engages at its projection 29 with the base p~ate 1 flexedly by said projection, the driver can o~erate said lever with certain feeling. In addition, as the lever 27 is made of plas-tics and fitted to the base plate flexedly, the employment of 10 spring washers is eliminated.
As stated above, the child locking mechanisms of this invention employ the lever 23 provided with the idle slot.
This enables that even when the interior door handle is pulled and when the door is child locked, the handle keeps its actuation mechanisms idle without giving u~natural force to them. Also as stated above, the lever 27 of child locking mechanisms is made of plastics, as a whle, resulting in the elimination of spring washers and in making it easy to make. As the connec-ting pin 26, arm 34, pro~ection 35 and extensions 36, 36 are 20 integrally made of plastics, their manuacture is easy.
In addition, as the projection 32 of the plastic lever 27 resiliently and pressedly engases with either one of recesses 32, and accordingly it can assu~e its selecteà position by itself, the provision of over-centering spring to the base plate is also eliminated.
