The latches disclosed in this application are of the type wherein a push button, lock operated, member associated with a vehicle door handle serves to release the latch. This type of latch is described and claimed in Craig Patent No.

2,204,208, granted June 1-1, 1940, and operation is on the principle of rendering an outside door push button ineffective to release the 'bolt by use of members nounted for dual movement and wherein the bolt is released when a release member is moved in one direction while another member is turned to one position and wherein the bolt will not be released when the release'member is similarlymoved while the; second member is moved to anotherposition and wherein looking may be efiected without a key by operation of a manual member while the door is being closed withthe latch thereof locked.

The latches in the present disclosure are also of the'type shown in Craig Patent No. 2,450,372, granted September23, 194.8.

Referring to the drawing by reference characters,. the invention is shown as embodied in a coincidental door-locking system wherein the latches are arranged upon a multi-door vehicle and wherein means extending between the latches causes them to be all locked or all unlocked coincidentally.

As shown each latch includes a base plate 10, which is suitably attached to the door I). The base plate has a-flange ll thereon, which is provided with'a slot 12 through which a pivoted bolt 13 protrudes. The bolt 13 is shown as pivotally mounted on the base 10 asat 14 and at its outer endsupports a roller l5 The protruding roller I5 moves in an inclined slot 16 in ja-strike member ll. arranged upon the pillar 18. The slot I6 is inclined so that as each door closes its associated roller moves from one end of the slot 16 towards the other end to fully engaged position behind the portion 19 of the slot. To hold the bolt in this position and thereby hold the door closed, a catch member 20 is pivotally supported at 2| upon the base 10, and includes notched portions 22 and 23.

The bolt l3 includes an inwardly directed pin 24 which rests upon the notched portion 22 when the bolt is in the down or disengaged position, as shown in broken lines in Fig. 9. When the bolt is raised to safety latched position the pin engages the notch 23 and when the bolt is raised to fully engaged position (full lines in Fig. 9),

the bolt engages the bevelled portion 25, just above the notch 23. When so engaged the bolt cannot move downwardly to disengaged position until the catch member 20 is swung and is released, as will be hereinafter described. A tongue 25 the base limits the movement of the catch member in one direction.

One end of a spring 26,, arranged about the pivot pin 14, engages a pin 2] on the catch 20 and urges the catch 20 to bolt holding position (full lines in Fig. 9), while the other end of the spring 26 engages a pin 28 on the bolt [3 to normally urge the bolt downwardly to disengaged position.

To release the-bolt by means of an inside remote control, an inside door handle 29 is shown. This handle includesan arm 30,. disposed inside the door and adapted to be rocked by thehandle 29. The arm 30 is connected to -one end of a rod 3!, the other end of "the rod .3! fitting in .a hole 32 in a rock arm 33 which is pivoted on the pivot 2 l. The lower end of the rock arm engages an actuating pin 10 mounted on a latch releasing member 40 .(both to be later described). "The rock arm will thus move the pin is and the pin will move the catch 29. Thus when the handle is rocked to the left in Fig. 2, the rod 31 will be pulled to rock the catch member 20 to the broken line position in Fig. .9, thus permitting the spring 25 to move the latch bolt to disengaged .position as the door is opened.

In order toprovide means, exterior of the vehicle for releasing the catch members '20 and also to provide means for locking the release means against unwarranted o ration, locking member 34 is provided for each catch. Each locking member is pivoted on a-pivot 35 on the base 10. One end of the locking member .34 is raised as at 36 and asnap-oiver spring '35 is arranged between this portion 34' and the base l0 to hold the locking member in either one of its two position. Tongues "35" struck from the base 10 limit movement of the locking member,

The locking member 1321 includes a protrud ing portion 36 which exte'ndsthrough a slot '31 in the ,fiange I l. Thepo'rtion fifi is formed into a cylindrical shape to support a roller '31.

The locking member is similar in some respects, to theloeking member shown in Fig. 3 2 of the applicants prior Patent No. agzogzoalmentioned above. a V

As shown, the locking member is provided with guide tongues 33 which slidablysupport a latch release member 40, which is movable to andfrom latch releasing position, as will be hereinafter described. The latch releasing member includes an extension portion M, which is 'slidable in a hole 42 in the portion35.

The latchirjeleasing member is limited in its.

movement away from latch {releasing portion by a tongue 45 which is struck up from the locking member 34.

The locking member 34 includes an elongated slot 46, which is wider at one end than at the other end is aligned with a slot 41 in the base it, and the latch releasing member 49 is also provided with a substantially trapezoidal shaped slot 48, aligned with the slots 46 and 41. These slots 46, 47, and 43 receive a releasing arm 49, which may be operated from the exterior of the door, as will be now described.

The releasing arm 49 is carried by an outside actuator, indicated generally at 59 (see Fig. 3). As shown the actuator includes a body having a hand grip 52 thereon. A screw 52' holds the body 5| in place. 7

The body 5| includes a bore 53 in which a push member 54 isarranged. The push member 54 includes a flanged portion 55, which normally is urged against a shoulder 56 by a spring 51, which also engages a flange 58 on a rotary support 59. A guide washer 69 engages the end of the flange 58 and a split spring 6! holds the parts assembled.

The push member 54,'as shown, is in the nature of a lock, the details of which form no part of the present invention. This lock is adapted to be rotated by a key 62 and when the key is inserted and turned the flanged portion 55 will be moved in one direction or the other, depending on whether the key is moved to locked or unlocked position. The key is returned to a normal intermediate position for removal.

The push member 54 includes holes 63, in which pins 64 on the support 59 are arranged to slide. The pins 64 cause the support 59 to rotate with the lock barrel push member 54 and also allow the lock barrel member to slide axially relative to the support 59. The support 59 includes depending ears 95, on which the arm 49, previously described is pivoted as at 66. V

The arm 49 includes a bell crank portion 61 which is engaged by a depending pin 68 on the lower portion of the barrel push member 54 and the construction is such that the arm 49 rotates with the lock barrel push member 54 about the axis of the lock barrel push member when the latter is turned. This rotation is through a very small angle limited by the engagement of the free end of the arm 49 with the upper edge of the slot 48 when the locking member 49 is in unlocked position (see Fig. 2) and the lower edge of the slot 49 when the member 40 is in locked position. The arm 49 is also rocked by the push member when the latter moves axially. As stated, the arm 49 extends through the slots 46, 41 and 48, the slot 4'! being of a size so that it is not engaged by the releasing arm 49; The slot 48' is of a length to comfortably receive the releasing arm 49 so that as the push member 54 is pushed inwardly, the arm i9is rocked, thus by engage ment of one edge of the arm 49 with one side of the slot 48 moving the latch releasing member 49 to the right in Fig. 9. 1

This will cause a pin 19 on the latch releasing member 49 to engage a tongue II on the catch member 29, causing the catch member to be rocked to the broken line position in Fig. 9, thus releasing the bolt l3 so that the latter may be moved downwardly by the spring 26, as the door opens. V

This last described action occurs when the locking member is in the unlocked-that isthe full line position shown in Fig. 9. Whenthe locking member, 34 is moved to the-broken line POS1- 6 tion shown in Fig. 9, as by pushing downward on a push wire 12 which hasa finger tip button 73 thereon, accessible from within the vehicle or by turning the key 62 and rocking the arm 49 as previously described so that the locking member assumes the position shown in Fig. 9, the locking member will be rocked about its pivot 35, and will be held by the spring 36, so that the pin 19 will be in the broken line position in Fig. 9. In this lat ter condition when the releasing arm 49 is rocked to shift the latch releasing member 49, the pin 19 will move into a notch 74 in the catch member 29. Full movement of the arm 49 will not cause the pin 19 to engage the end wall of the slot 74 to rock the catch member 29 to releasing position and thus there Will be no releasing action by movement of the latch releasing member 49.

From the foregoing description it will be apparent thatthe latch may be released, by operating the push member 54 when the locking member 34 is in one position and that a similar operation of the pushing member 54 when the locking member 34 is in the other position will not serve to open the door. However, the inside release member 29 may be operated to release the catch member and to free the bolt regardless of which position (locked or unlocked) the locking member happens to be in.

In order to prevent a vehicle operator from locking himself out of the vehicle through inadvertently closing the door when the locking member 34 is in locked position, the catch member 29 is provided with a restoring pin 75 which is disposed adjacent to and is adapted to engage the lower edge 16 of the catch releasing member 49. The edge is curved upwardly slightly at 16 to keep the pin 15 always in engagement with the member 49 when said member is in a locked or unlocked position. The pin 75 is disposed at one side of the aXis of the pivot 35 and the construction is such that when the catch member 29 is rocked by the spring 26 as the door is closed the pin 15 will shift with the catch member 29. Thus when the parts are in the position shown in broken lines in Fig. 9, (that is in the locked condition), and the member 29 is rocked as just described in the act of closing the door, the pin 15 will move upwardly slightly in Fig. 9 and will engage the edge !6 of the latch releasing member 49 and will rock the member 49 upwardly. The member 49 is carried on the locking member 34,

and the arrangement of parts is such that the locking member 49 will be moved to unlocked position, where it will be held by the spring 35'. Thus the likelihood of any operator locking himself out of the vehicle due to thoughtless closing of the door when the latch is locked will be prevented. 7

Should the button 13 looking member 34 be in its locked position, actuation of the inside handle 9 33 to be rocked and, by engagement with the pin 19, movethe member 49 to its extreme rightward position in Fig; 9 to cause the inward edge of the notch 14 to rock the catch member 29 and release the bolt I3. By engagement of the pin 15 with the edge 15, the member 34 will be moved over its center position, and the construction is such that is actuated the pin 79 will move along the edge 14' of the notch 14, permitting the locking mem' ber 34 to'return to its unlocked position, thus leaving the open door in an unlocked condition. The lever 33- is suitably curved to permit the pin 19 to'be moved withithelocking assembly with? out disturbing the'lever 33 be depressed and the 29 will cause the lever pin 79 to engage the 7 when the inside handle However, should the operator desire to lock the vehicle door without the use of a key he may operate the push button 13 on a door, moving the locking member 34 on that door to locked position (that is the broken line position in Fig. 9) whereupon the operator will press the push button 54 on the same door and in doing this will move the latch releasing member 46 to the right in Fig. 9. This movement will move the member fit so that the pin 5 will be moved from the edge 15 and will be aligned with :a slot in the latch releasing member it. Thus when the door is closed and the catch member 29 moves, the pin 7 will pas into the slot '39 and will not engage the edge i5 and therefore the locking member 34 will remain locked.

Thus by dual manipulation-that is by pushing on the push member 54 and at the same time closing the door when the locking member 34 is in looking position the operator will cause the parts to remain locked. Further, as here inafter explained, due to a coincidental locking system to be later described, this dual act will also cause all of the other doors besides the one door being closed to be locked regardless of whether the other doors were in locked or unlocked position when the one door was closed.

The latches described above may be used individually as single latches. They may also be used with a coincidental locking device and/or with a vehicle speed control for releasing the latches as will be later described.

'For coincidental locking the rollers 33' on the lock members 3d of adjacent door latches are adapted to move into substantially U-shapcd wings 3b mounted at the two ends of a locking bar 8! which has a lever 82 connected thereto. The bar ti includes arms 83 which are pivoted as at 8 5 to uprights S5 struck from a base 85 of a speed control and lock assembly 86 shown in Fig. 8. The uprights 85 are supported by braces 85 bent up from the base $6. This assembly also includes a vertical portion '8'! which supports the barrel 88 of a key operated look as shown in elevation in Figs. 3 and 7, the oper ating details of which form no part of the present invention. The lock 88 includes a projecting cylindrical member 89 which has a crank 90 mounted thereon and the crank d5 includes a crank pin 5i which fits in the slot 92 in the locking bariii.

The lock is adapted to be turned by a key 88' from a-neutral position in either direction. This turning or the lock moves the crank 90 from an upper position to a lower position, and vice-versa, and in so doing the pin e: moving in the slot92 in the locking bar 3! raises and lowers the bar 8i and thus raises and lowers the wings 3B.

The lever 82 on one side of the vehicle is connected by a Bowden wire 93 with a similar lever 82 on the other side of the vehicle, with the Bowden wire preferably passing beneath the vehiclebody. The Bowden wires are so connected to the levers that when the lever on one side is depressed or raised the lever on the other side of the vehicle, will be also depressed or raised.

The speed control and lock assembly may be inserted through the front of each pillar through a removable panel l8 therein and is advanced and suitably secured in a position wherein the wings 83 are disposed as shown in Fig. 3 to receive the rollers 33' when the door is closed. A snap-over spring 95 lFigs. '7 and 8) holdsbar 8i and wings as in either up 'OI' (1QWI 1 position after they have been moved to such positions. Stops 96 limit the movement of the bar 8!.

When two adjacent doors are closed and the rollers 31 are in the wings with the locking bar 8! in the position shown in Fig. 8, the looking members 34 will be in a position to cause the associated latches to be unlocked. When. under this condition, a key is inserted in the lock 88 and the lock 88 is moved to locked position, that is the lock is moved so that the pin 9| is lowered and the locking bar ill is moved downwardly the wings at will move downwardly and thus will move the rollers 37' and will move the associated locking members 34 downwardly so that the latter will be in locked position.

The slot 92 is of a shape to permit the pin iii to move up and down therein. The lock 88 is preferably of the well known character wherein the key 38' must be turned to a normal intermediate position before the key can be removed. When the pin is in this normal position and the wings 8% are in locked position (as in Fig. 8) the pin will be adjacent to the lower face of the slot Q2 and when the wings 80 are in. the reverse position the pin will be adjacent to the upper edge of the slot. This allows the Wings 80 to be moved to locked and to unlocked position by the lever 82 independent of the position of the pin 9!.

As the wings move about the pivot 84 from locked to unlocked position, there is a slight forward and backward movement of the wings relative to the face 8?. The wing "supports however are slightly flexible and are rather loosely fitted together so that this slight movement of the wings so does not cause a binding action due to the rollers is? pressing against the wings.

When any key 62 or a latch is turned from locked to unlocked position or vice-verse, the releasing arm 59- will be rotated about the axis of the push member 5% and will be swung upwardly or downwardly. The releasing arm it will be noted operates in a slot 56 in the washer 68. The key 52 must be in unlocked position with the member ts in normal intermediate position when the key is removed and when in this position the releasing arm 49 will fit in the slot d3 as shown in Fig. 2 when the device is unlocked. The slot 58 is shaped to permit the releasing arm to fit therein in reverse position when the latch is locked.

By rotating the key 62 it will be seen that the releasing arm ts will be rocked about its axis (which coincides with the axis of the push member 54) and will raise the locking member 34 upwardly or downwardly, depending upon the direction of movement of the releasing arm. This upward or downward movement of the releasing arm will cause similar movement of the members 3 1 and 4b and will likewise shift the rollers 37 upwardly or downwardly and thereby shift the wings S8 in a similar direction and manner.

Thus it will be apparent that all the latches on closed doors can be coincidentally locked either by operating the key 88' in the lock member 88 or by operating the key 62 in any one door handle or by pushing down any locking member I3 or by rocking the lever 82.

The vertical position 81 of each speed control and lock assembly 86' has a tongue I60 extending at right angles thereto and this tongue includes a downwardly bent end lfll which carried a pivot pin I82 which supports a downwardly dependinggenerally. U-shaped spring 4&3. The

spring includes a pair of opposed vertical portions I04 from which opposed inclined tabs I03 extend. The spring includes downwardly converging portions I05 which terminate in short vertical tongues I06 which normally are slightly spaced apart by the resiliency of the spring material. A solenoid I01 on the base 86 has an armature I 08 which has a rounded end I09 which when the solenoid is energized, moves between the tongues I06.

To energize the solenoid I 01 one lead I I therefrom is shown aspassing to a contact I II on an arcuate circuit closer H2. The other lead H3 extends through a source of current H4 to the needle II 5 of a vehicle driven speedometer H6 and the construction is such that when the speedometer needle I I5 is moved when the vehicle goes into motion this needle will close the circuit from the lead III] to I I3 and thus will energize the solenoid and cause the armature to move upwardly against the tension of a spring I". When the vehicle speed decreases to a predetermined rate, the solenoid will be de-energized and the spring II! will lower the pin I08.

The spring I03 is of such character that normally the vertical portion I04 may be moved inwardly easily when the solenoid is not energized.

The latch releasing member extensions 4! previously mentioned are in the nature of speed controlled feelers and each of these extensions has its free end adjacent to the vertical portion I04 of the spring. Thus when the latch releasing member starts its movement towards latch releasing position the associated extension 4! will engage the spring portion I04. When the solenoid is not energized the spring will bend easily and thus there will be no resistance to the operation of the latch releasing member. When, however, the solenoid is energized and the solenoid armature I08 is between the tongues I06 the spring can be flexed only under great force and at this time it will require great pressure to move the latch releasing member .to latch releasing position.

Thus it will be seen that when the vehicle is at rest the latches may be released from within or from Without the vehicle to open the doors with only a light finger tip pressure. However, when the vehicle is moving above a predetermined rate of speed the latch releasing members can only be operated with difliculty. Thus accidental door opening is prevented while at the same timethe fear of riders who object to riding in a vehicle the doors of which are locked against opening is overcome.

To open the dors from without, pressure on the push member 54 will rock the releasing arm 49 and will cause the associated latch releasing member to be moved by the arm 49 to releasing position. If the locking mechanism is in locked condition movement of the arm '49 will merely cause the latch releasing member to move idly since in that position the pin 10 will move into the notch 14.-

In closing the door when all of the latches are unlocked and the locking lever 02 is in unlocked position with the parts as shown in Fig. 2, the operator merely closes the door and the parts remain in the condtiion shown in Fig. 2. When in this condition from within the vehicle all doors may be locked by pushing on any one button I3 or by rocking the lever 82 to locked position. The upward movement of either of the levers 82 will rock the bar 00 and the wings 8!. The wings 8|, engaging the rollers 01, will rock the latter and will thus rock the locking members 34 to locked position. A reverse movement of either lever 82 will move the locking members 34 to unlocked position. From without the vehicle all doors may be locked by moving the key 62 or the key 88' to locked position. All doors may be unlocked when they are locked by reversal of the operations just described.

In operation and assuming that all doors are closed and that the vehicle is at rest, the operator may turn any remote control handle 29 thus causing the rod 3! to rock the catch member 20 and thus free the associated bolt. When the bolt is freed opening of the door causes the roller I5 to move along the groove I IS and then to pass from this groove.

If the vehicle is at rest when the above operation takes place the extension II on the latch release member will engage the associated vertical portion I 04 of the spring and will push that portion without difficulty. When, however, the vehicle is running and the solenoid armature I 09 is disposed between the tongues I06 the force required to move the portion I04 of the associated spring will be such that the operator 29 can be actuated only with great difiiculty. Thus accidental opening of the door is prevented.

The above described operation of opening any door from within by operating the remote control handle 29 applies regardless of whether or not the latches are in locked or unlocked condition.

Assuming now that certain of the doors are closed and that the locking mechanism for the closed doors is in locked condition. Now if an operator closes another door the locking member 34 of which is in unlocked condition this will cause the roller 31' on the one door to move its wing thus causing all of the wings to move to unlocked position. This is done by the roller 3'! camming against the adjacent portion of the wing 80 thus shifting the wing 80. This occurs while the catch member 20 is being rocked by the pin 24 passing from notch 22 to notch 23 and to edge 24, so that the pin 15 holds the locking member 34 in the position shown in Fig. 2 and thus overcomes the tension of the springs '35 and which tend to hold the doors previously locked in that condition. v

Assuming now that certain of the doors are closed and that the locking mechanism for the closed doors is in unlocked condition and that the operator wishes to cause all of the doors to be locked. The operator will press down on the push button 13 on the door which is being closed. this will place the locking member 34 of the door being closed in locked. condition. The operator will thereupon. press the push member 54 inwardly and will at the same time close the door. In this positionmovement of the catch member 20 by its engagement with the pin 24 on the bolt will take place with the pin 75 on the catch member passing into the slot I9 and the pin 10 will be disposed in the notch I4. In this condition the roller I9 will enter its associated wing 00. The pin I0 will then engage the edge M of the notch l4 thus preventing the locking member 34 from shifting to unlocking position and the roller 31 will thus pass into its associated wing 00 and will pull this wing from unlocked condition to locked condition and will cause all of the other wings to move to locked condition.

When any door is closed with the push mem ber 54 moved inwardly as in the operation described in the preceding paragraph the extension 41 will be advanced and as the door closes will strike the inclined tab I03 on the spring H13 and as it moves along the tab will push the portion Hi4 of the spring inwardly so that the parts assume the position shown in Fig. 3. The spring will offer no substantial resistance to this movement when the vehicle is at rest but should a door be closed while a vehicle. is in motion so that the solenoid armature end is between the ends Hi8 of the spring an, added force must be applied to the door in closing the same.

Assuming now that certain of the doors are closed and are unlocked and that the operator closes one door which unknown to him has been placed in locked position, then in this circumstance when the operator closes this one door without. pressing on the push member 54 the one door will become unlocked and the others will remain unlocked.

It will be understood. under certain installations the. lock 88 on the pillars may be omitted and only the key operated locks 62 may be employed. Also under other conditions it may be desirable to omit the locks operated by the key 62 and make the members 54 merely push members and depend only on the locks 88 as the key operated members.

From the foregoing description it will be apparent that the present disclosure relates to a novel latch construction which, if desired, may include coincidental locking mechanism and/ or safety release controls and wherein the parts act in eflectivemanner to perform their intended functions.
