FIGQIO ATTORNEYS SHEET 5 BF 5 INVENTOR JOSEPH P ICKLES ATTORNEYS AUTOMOBILE noon LOCK BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to automobile door lock structures and, more particularly, the overrunning or free-wheeling class thereof in which a manual inside and/or outside operated handle or push button is, in a locked condition of the structure, disabled from transmitting unlatching effortto a latch holding detent. This type of locking action is to be distinguished from that of a lock in which the operator is positively blocked by meanS of some sort from operating the detent to unlatch the lock.

2. Description of the Prior Art The most pertinent prior art US. Pats. of which I am aware are Shay No. 3,359,026 of Dec. 19, 1967, Slattery No. 3,384,404 of May 21, 1968 and Dale No. 3,388,940 of June 18, 1968. These relate to arrangements to disable a manual operator by free-wheeling or overrunning it in relation to a detent, and in a general way to locking kick-oif and reset means. However, none of these patents show or suggest such provisions of a medially pivoted, rocker-type locking lever or control arm which is manually operable selectively from an inside push button, the outside key-operated linkage and the inside remote operator. Nor do they disclose an automatic kick-off and reset member slidably mounted to shift bodily on the locking lever in a single stroke between kick-off and reset positions, thus affording an improved and simplified kind of keyless locking as hereinafter described.

SUMMARY OF THE INVENTION The lock of the invention affords, essentially by reason of a single, medially pivoted control rocker arm or looking lever equipped between its ends with a pivotally depending transmitter element, and with a kick-off and reset slide adjustable lengthwise on the arm, the abilities to automatically lock an automobile door closed, without key and by performing two simple sequential preset steps. An automatic damage-preventing kick-off from locked to unlocked condition when the door is slammed shut is also a feature. The manual unlocking and locking actions may derive from either the usual push button at the inside door garnish molding or the usual inside-operated remote control handle, just as theymay result from the operation of an outside tumbler and key lock. Moreover, keyless locking from the outside may be had without the need to hold the outside handle or finger button depressed while slamming the door shut with the lock previously set in a" locked condition. In all cases the locking action is a free-wheeling one, not a blocking one.

The parts are extremely simple and inexpensive, yet adequately sturdy, inasmuch as neither the locking lever or rocker nor its associated transmitter is subject to appreciable stress in the unlocked, force transmitting condition of the lock. Of course, neither are subject to any stress at all in the locked, free-wheeling or overrunning condition. The locking linkage is shown herein as beinG applied to an automobile lock of the type in which a forked latching member or plate is pivotally mounted to straddle a keeper pin in the door-latched condition. However, a similar arrangement is obviously applicable to a lock of the rolling bolt type.

DESCRIPTION OF PREFERRED EMBODIMENTS The simpler version of the improved lock of the invention, generally designated by the reference numeral 10, comprises, in common with other locks of generally similar type, a mounting and housing structure 11 in the form of a U-shaped plate having

parallel side flanges

12, 13. The plate has holes 14 for the reception of screw or bolt means by'which it is rigidly attached to an inner panel, not shown, of an automobile door, these openings being in a main body plate portion 15 of main housing plate 1 1 and an upper flange or ear formation 15 thereof. Housing flanGe .13 has an aperture 16 (FIG. I) which goes over a keeper bracket 17 fixed on the automobile door post (not shown) when the door is closed; and bracket 17 carries a keeper or striker pin 18. In the usual fashion, pin 18 is straddled by a fork recess 19 in a latching plate 20 of the lock when the lock is wholly or partially latched, and the plate 20 is strongly urged in the counterclockwise direction, as viewed in FIG. 1, by a spring 23 anchored to housing portion 15, encircling the pivot 22 and acting in a notch 24 in the plate. Typically, plate 20 is formed to provide tooth-

like abutments

25, 26 on its periphery. The casing or housing structure 1 1 is completed by a closure plate 27 (FIG. 2) suitable secured rigidly to the remainder of the housing, as at the

flanges

12, 13.

A latch-engaging detent, generally designated 28, is in the form of a bell crank of inverted V-shape, which is pivotally mounted by a pin 29 to the body portion 15 of housing 1 1, adjacent the upper end of the latter. The detent 28 is strongly urged clockwise (FIG. I) by a coil spring 30 anchored to the housing portion and acting against the detent at an offset end 31.

One arm 33 of detent 28 is thus urged clockwise against latching plate 20 and, in the latched condition of the latter of FIG. 1, contacts. the plate abutment 25 to hold the lock latched. The other arm 34 of detent 28, in this position of the latter, depends closely adjacent and just within the housing flange 12. Arm 34 is provided with a vertically elongated slot 35 in a laterally offset portion 36 thereof, for a purpose which will appear. An essentially important feature of the improved lock resides in an elongated locking control rocker arm or lever 38 which is pivotally mounted, as by a pin 39,0n the housing closure plate 27, which arm 38 is in a vertical plane between the plate 27 and the detent 28. The pivot point at 39 is at the approximate longitudinal center of arm 38.

As best illustrated in FIG. 1, rocker arm 38 terminates at its left-hand end in a portion apertured at 41 for connection with an appropriate linkage (not shown) which is actuable by an external tumbler and barrel type, key operated lock. Manipulation of the key in unlocking lock 10 is effective to swing locking control arm 38 counterclockwise to the position of FIG. 1, in which the lock 10 is shown as being latched by detent arm 33. Clockwise operation of arm 38 by the key places control arm 38 and the lock in a disabled and locked, freewheeling or overrunning condition in respect to its inside and outside operators, as will be described.

The opposite or right-hand end (FIG. 1) of rocker arm 38 is formed, as by aperturing at 42, for engagement by a linkage from the usual pushbutton means (neither shown) at the inside window trim molding of the automobile door; and clockwise and counterclockwise swing of arm 38 through such an inside locking control agency places lock 10 in the respective locked and unlocked conditions just described.

Locking contrOl arm '38 is also actuable directly from the usual inside remote control or door handle by means of a bell crank or lever arrangement, generally designated 44, hereinafter described in detail; and actuation of the arm 38 by this means also conditions the latter and its transmitter (to be described) in the same way as does actuation by the outside barrel lock key and the molding push button.

An over center type of coiled spring 45, anchored to housing closure plate 27 and acting on control arm 38 at 46, provides the usual over-center snap action in the pivotal shift of arm 38 in one direction or another.

Locking control rocker arm 38 has a force transmitter or contactor finger 48 pivotally mounted in depending relation thereto ata point between arm pivot 39 and the left-hand, key-operated end of the arm, as viewed in FIG. 1. This finger is provided adjacent its lower end with an integral, transversely offset ear 49 which, as illustrated best in FIGS. 1, 2 and 4, extends laterally into the vertically elongated slot 35 of the depending arm 34 of detent 28. Transmitter finger 48 has a relatively loose depending pivotal connection at its top to the arm 38, as at an offset 50 received in an opening 51 (FIGS. 2 and 4) in arm 38.

As best shown in FIG. 2, the outside unlatching operator of lock 10 is in the form of a lever or arm 52 adapted to be connected at an opening 53 adjacent one end thereof by appropriate linkage means (not shown) to an external operating handle, button or like means on the door adjacent its key lock. Actuator 52 is pivotally mounted by a pin 54 on a lateral ear 55 offset from housing closure plate 27, the pin also serving as a pivot for the inside or remote control unlatching operator, as will be described.

Outside operator arm 52 is bluntly T-shaped in outline, being formed intermediate the length thereof to provide an offset nose 56 which, in the neutral position of the operator shown in FIG. 2, lies just outwardly of the offset ear 49 of the transmitter 48. Accordingly, a clockwise motion (FIG. 2) of outside operator arm 52 about its pivot at 54 causes transmitter 48 to be swung to the right by operator nose 56, or from the solid to the dotted-line position of FIG. 1. Thus, if lock 10 is in the latched and unlocked or operative condition of FIGS. 1 and 2, with the transmitter ear 49 in the slot 35 of the depending detent arm 34, detent 28 is swung counterclockwise (FIG. 1) to release its other arm 33 from holding engagement with the abutment 25 of latching plate 20.

Accordingly, the plate is urged counterclockwise by spring 23 to an unlatched position, in which the holding or keeper recess 19 of the latch plate is released from the door postmounted keeper pin 18. The same occurs in the event detent arm 33 has been engaged by the second abutment 26 or plate 20, in a condition in which the door is but partially or safetylatched.

In the unlatching movement of outside operator 52 the latter swings from the solid to the dot-dash line position of FIG. 2, i.e., clockwise about its pivot at 54. counterclockwise movement of operator 52 is limited by a rounded nose formation 57 on the end of the operator opposite that at which it is controlled, the formation having stop engagement with the outside of housing closure plate 27.

An inside or remote control actuated unlatching operator arm of lock 10 is designated 58. It is in the form of a hookshaped bail pivoted by pin 54 on the casing part 55 in common with, but directly above, the outside operator 52; and the inside operator 58 has an actuator nose 56' shaped identical to the nose 56 of outside operator 52. These two nose parts are vertically superposed in identical register, as viewed in FIG. 2, when in neutral unactuated position.

As in the case of outside operator 52, upon a clockwise swing of inside operator 58 from the solid to the dot-dash line position of FIG. 2, the offset transmitter ear 59 is engaged and detent 48 is pivoted counterclockwise, unlatching the lock,on the assumption offset car 49 is in a vertical relation to detent arm slot 35 to be engaged by the inside operator 58, i.e., that the structure is in an unlocked condition. Again, this is determined by the position of locking control rocker arm 38. When the latter raises, both of the

operators

52 and 58 free-wheel past it and are disabled as to unlatching effect.

The arm 38, in addition to being controllable by non-unlatching outside key means (at 41) and inside push button means (at 42), may also be selectively positioned, with the same results, by the inside or remote control handle which actuates inside operator arm 58 and lever unit 44.

As best shown in FIG. 3, this may be through the agency of a small bell crank 60 pivoted by a pin 61 on a laterally offset ear 62 which is struck from housing closure plate 27. One arm 63 of crank 60 is shown as being provided with an opening at 64, where it maybe operatively connected by a suitable linkage (not shown) to the inside remote control handle of the door. This is done in such a fashion that a movement of the handle in a non-unlatching direction will lock the door. That is, bell crank 60 is swung clockwise about its pivot 61 (FIG. 3) in this locking action.

The second arm 64 of bell crank 60 is forked at 65 to straddle a reduced width portion 66 of control member 38, just inwardly of its push button operated end at 42, as shown in FIG. 1. A clockwise movement (FIG. 3) of bell crank 60 causes the control arm 38 to be swung clockwise (FIG. 1) about its pivot at 39, with the result that transmitter 48 is lifted to a disabling position, out of the path of the

operators

52 and 58. When the lock is unlatched from the inside of the door, or when the inside operator is moved toward a neutral position short of its unlatching position, a reverse action of hell crank 60 on arm 38 occurs and the parts are restored to the position of FIG. 1.

It is evident that, as embodied in the structure of FIGS. l-6, the invention affords an automobile door lock which is structurally of a very simple character, in which all of the essential unlatching, locking and unlocking actions involve the use of a transmitter-carrying rocker type locking lever or arm member, operated in coaction with a pivoted detent and inside and outside operators, which operators act directly adjacent one another in parallel planes, with the locking lever operating in a plane at to said planes.

A more refined and versatile version 70 of the improved lock appears in FIGS. 7-18, inclusive, of which FIGS. 10, 11, 16, 17 and 18 supplement in a clearer way the relatively cornplex showing in FIG. 7 of the entire combination of parts. For simplicity a number of component housing, actuator, latching and other parts which are identical, or basically correspond, to parts appearing in FIGS. 1-6 are designated by corresponding reference numerals, primed, and further description thereof, and of their function, will be dispensed with. Further in the interest of simplicity, 'certain provisions illustrated and described in FIGS. 1-6, for example, the inside or remote controLoperated bell crank or lever means 44, are not shown, though actually present, in order not to obscure other features.

A special latch holding detent or pawl of the lock 70 as best shown in FIG. 11, is generally designated by the reference numeral 72. Like detent 28, it comprises a latching dog or arm 73 releasably engageable with the latch members shoulder 25' to hold the lock in the latched position, and the arm 73 carries a laterally offset kick-off lug 74 for a purpose to be described.

The detent 72 is, generally speaking and as best shown in FIG. 11, of inverted V-shaped outline, and is pivotally mounted on one of the lock housing walls by means of a transverse pin 75. A coiled operating spring 76 encircles this pin, one end of the spring being housinganchored, as in the first form. The opposite spring end 76' hooks around a lip portion 77 on and adjacent the fork of detent 72, in a manner to normally urge the latter in the clockwise direction, as viewed in FIG. 11.

The detent provides a downwardly depending, integral hook-shaped actuator arm 78, through the agency of which the detent is swingably operated by one or the other of the two horizontal actuators 52, 58' through an intermediate agency borne by the transmitter, as will be described.

A special rocker type locking arm or lever member, generally designated by the reference numeral 80, is pivoted by a pin 81, at its approximate mid-point, between the housing walls, this locking

arm having apertures

82,83 to receive, respectively, operating connections (not shown) to the usual door key lock and to the push button normally mounted through the inside garnish molding of the door. Manipulation of either of these controls swings locking member 80 pivotally about its axis between the latched and locked condition of FIG. 16 and the opposite condition of FIG. 17, i.e., the unlatched and unlocked condition. FIG. 18 shows another, reset condition in which the lock has been unlatched, but the locking rocker arm has been placed in a locking position,from which it must be manually shifted or automatically kicked off.

Upon one arm portion of locking member 80 (right hand in FIGS. I6-18 and left hand in FIG. an elongated, generally horizontal slot 85 is formed, past which slot the lug 74 of detent 72 moves when the latter goes counterclockwise'from latch holding position to latch releasing position. The other arm portion of rocker 80 is provided with a rectangular opening 86 for a purpose to be described.

In addition, member 80 is provided with an integral, downwardly projecting lug 87 of L-shaped outline, including (FIGS. 9 and 10) a horizontal offset at 88 and a short leg portion 89 depending from the latter. A snap-over type coil spring 91 having one end anchored to a housing plate and the other end anchored to a portion of the locking arm 80 adjacent its slot 85 exerts the usual effort of snapping the arm over center in its clockwise or counterclockwise action.

The specially shaped lug 87 of the locking lever or arm 80 serves to pivot a downwardly depending transmitter member 92, as at a circular aperture 93 of the latter which is slipped over the rocker arm lug 87, the transmitter 92 swinging freely from this pivotal mount. The transmitter 92 is provided with a laterally extending, vertically elongated flange 94 which, as illustrated in FIG. 9, is of sufficient width at its top to extend behind the depending integral hook arm 78 of detent 72, so that in the unlocked condition a counterclockwise swinging of transmitter 92 (FIGS. 7, 16, 17 and 18) by either of the outside or inside manipulated actuators 52', 58, respectively, will cause the transmitter flange 94, in engaging detent arm 78, to swing the detent 72 counterclockwise, thus releasing the latters holding arm portion 73 from latching engagement with the shoulder 25' of latch member.

The transmitter 92, unlike transmitter 48 of the first embodiment, is also swung by outside actuator 52 when in a locked position, but without operating detent arm 78. It is for this reason that that arm is given its hooked outline appearing in FIG. 11, and for the same reason the flange 94 on transmitter 92 is also specially shaped. As best seen in FIGS. 9 and 10, the flange 94 is vertically slitted at 95 intermediate its width and bent rearwardly to one side of the slit to afford a short force transmitting heel 96. This heel is engageable with and operates detent arm 78 when lock 70 is unlocked at the transmitter, i.e., when the latter is lowered by lever 80, but fails to swing sufficiently to engage and operate arm 78 in the locked condition (transmitter up), as Will be described further in reference to FIGS. 16 and 18. Other provisions hereinafter described are made at the levers locking, transmitting and reset slide for kicking off lever from locking to unlocking condition, also to pre-set thelever for automatic locking. The slide is designated 98 and is also later described.

To the extent that the operation of lock 70 resembles that of lock 10, the transmitter 92 may be lifted by locking lever 80 from the unlocked position of FIG. 18, in which its heel 96 can drive detent 72 to latch release position, to that of FIG. 16, in which its heel 96 fails to engage detent arm 78. In this case the detent 72 may not be actuated and released by the outside actuator, the transmitter 92 being disabled and free wheeling in respect to the detent. Transmitter 92 is lifted by locking arm 80 upon a clockwise movement of the latter about its pivot at 81.

As indicated above, the lock 70 is completed by the special locking kick-off and reset slide 98 on locking lever 80, and is best illustrated, per se, in the perspective view of FIG. 15. As associated with lever 80 in the manner shown in FIGS. 10 and 16-18, it has a generally horizontal sliding action lengthwise of the lever, under snap-over assistance by an over-center coil spring 98' whose ends anchor to the slide and the locking lever. Slide 98 is supported solely by and at a side of locking lever 80, being provided with an integral offset, kick-off transmitter lug 99 adjacent one end thereof. This lug extends into the open-ended slot of the locking arm, and is of sufiicient lateral extent to be overlie and be in the path of the detent lug 74 when the lock 70 is in its latched and locked position of FIG. 16, i.e., with the locking lever 80 fully rotated clockwise about its pivot at 81 to disable the transmitter 92. In this position the reset lug 99 is positioned directly above detent lug 74, so as to be moved upwardly when detent 72 is swung counterclockwise.

This is also true in an unlatched and locked condition in which the lock 70 may be placed by operating locking lever 80 counterclockwise when the door is open and the detent portion 73 rests atop the latch plate abutment 26', in the manner of FIG. 18. Accordingly, if the door is now slammed shut without further manipulation the latch plate 20', in rotating counterclockwise under the influence of spring 23', causes the detent lug 74 to upwardly engage the overlying kick-off lug 99 of slide 98, so that the latter swings locking lever 80 counterclockwise to its unlocked position. This happens as latch plate 20 engages the locks keeper pin and swings to a latched but unlocked position, i.e., in an automatic locking kick-ofi action.

Locking and reset slide 98 is provided (FIG. 15) at its end opposite lug 99 with a second offset lug 100 at to the slide; and lug is received in the rectangular opening 86 of locking member 80, it being noted that in the case of both of the

lugs

99 and 100 there is space for some slight vertical play in slot 85 and hole 86, respectively. The opening 86 and slot 85 are of sufficient horizontal extent to permit the slide 98 to shift horizontally on lever 80 from the kick-off position of FIGS. 16 and 17 to a reset position of FIG. 18, and vice versa, and the vertical clearance allows for the swing action of locking lever 80.

Finally, slide 98 is formed to provide a third laterally offset lug 101 paralleling and in horizontally spaced relation its lug 100, but of less lateral extent than the latter; and an upright kick-ofi' and reset control ear 103 upwardly integral on transmitter 92 extends between

lugs

100 and 101 for apurpose to be described. An offset ear 62' on the housing plate 27 (FIGS. 8 and 9) pivotally mounts an inside, or remote controlled lever or hell crank unit, not shown but like the unit 44 80 in the manner previously described.

FIG. 17 illustrates one manner in which the slide 98 may be actuated, with the latch plate 20 spring-swung counterclockwise to an unlatched position, and locking lever 80 being swung clockwise to its locked position. As indicated above, if the slide 98 were in the position in its position to the right on lever 80, as illustrated in FIG. 16 (but not in FIG. 17), this would result, when the door is swung shut, in the latching and automatic unlocking of lock 70. However, an automatic retention of the lock in its locked condition as the door is closed, accompanied by latching, is possible with the lock parts disposed in locking preset position.

This simply involves, with locking lever 80 operated clockwise, as by a garnish mold push button and latch plate 20 in release position, an operation of one or another of the manual operators 52' and 58' in an unlatching direction, thus to engage the transmitter 92 and swing it counterclockwise, as viewed in FIG. 18. The result is that, although the transmitter has been elevated by locking lever 80 out of position to engage detent actuator arm 78, its mentioned swing causes the reset control ear 103 of transmitter 92, in engaging offset lug 100 of the slide 98, to shift the latter bodily to the left on locking lever 80. Hence the slides opposite lug 99 goes from a position overlying the detent lug 74 to a position at one side of the latter. Lock 70 is now preset forautomatic locking, without further manipulation by the driver when the unlatched and open door is swung closed, due only to the clockwise swinging of locking lever 80 and the manipulation of an

operator

52 or 58 in that chronological sequence. In going closed, the latch plate 20 cams detent 72 upwardly counterclockwise, but the lug 74 of the detent misses contact with reset lug 99 of slide 98, and as a consequence the locking lever 80 remains in its clockwise-swung position of FIG. 18, having been disabled at

lugs

74 and 99.

With the lock thus latched and in locked condition, when the locking lever 80 is swung counterclockwise to unlocking position, as through the agency of an outside key-operated linkage, the transmitter 92 swings clockwise about its pivot on the locking lever in being shifted downwardly by the latter; and the clockwise transmitter movement causes its reset car 103 to engage the intermediate lug 101 on slide 98. As the swing is continued, ear 103 thus moves the slide to the right, as viewed in FIGS. 16-18, thereby restoring its kick-off and reset lug 99 from its disabled position in relation to detent lug 74 to its operative kick-off position overlying lug 74. Lock 70 is now unlocked and, if unlatched as in FIG. 17, ready for preset to automatic locking by operation of the lever 80 and an operator 52' or 58 in the fashion described above.

Should it happen that, with the lock placed in its stated locking preset condition by the successive contemplated manipulations of lever 80 and an operator, the operator 52' or 58' should unnecessarily be held depressed, nothinG happens inasmuch as the detent operating arm 78 simply idles relative to the operators and the transmitter 92 as latch plate 20 goes to latching and locking position.

' The lock of FIGS. 7-18, inclusive, affords, in addition to advantageous features and actions had in common with the form of FIGS. 1-6, inclusive, a geometrically simple yet reliable combination of a singe reset slide on a medially pivoted locking lever of the rocker arm type, in which a single rectilinear shift of the slide on the lever from a righthand limit (FIGS. 16 and 17) to a lefthand limit (FIG. 18), and vice versa, conditions the lock 70 for automatic kick-off from locked condition and/or for nullification of the kick-E and placing the lock in a latched position without disturbing its locked state. These actions take place without any manual effort being exerted on the slide other than through lever 80, through an operator 52' or 58', and/or consequent to the effort of closing the door.

What is claimed is:
