DOOR HANDLE AND LOCK Filed Maj 1, 1939 INVENTOR Patented Nov. 19, 1940 UNITED STATES PATENT OFFICE noon HANDLE AND LOCK Ernam King, San Diego, Calif. ApplicationMay 1, 1939, Serial No. 271,137

2 Claims.-

The invention relates to a door handle and lock and more especially to a lock and handle assembly for motor vehicle doors.

The primary object of the invention is the provision of an assembly of this character, wherein a throw bolt can be locked in a thrown position so as to fasten a door closed and this bolt is control-led by handles arranged both at the inside and outside of the door, the assembly being of novel construction so that the bolt can be readily thrown to a released position for the unlocking of the door and when in a locking position will be held secure to avoid the opening of the door.

Another object of the invention is the provision of an assembly of this character, wherein the construction thereof is novel in its entirety and is adaptable for the concealment of the latching and locking mechanism within the door body while handles for operating the same are exposed both inside and outside of the door for manual operation.

A further object of the invention is the provision of an assembly of this character, which is simple in its construction, thoroughly reliable and efficient in operation, possessed of few parts yet strong, durable, and inexpensive to manufacture and install.

With these and other objects in view, the invention. consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawing, which dis closes the preferred and modified forms of embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is a fragmentary horizontal sectional view taken through a door for a motor vehicle showing the lock and handle assembly constructed in accordance with the invention applied.

Figure 2 is a fragmentary sectional view taken on the line 2-2 of Figure 1 looking in the direction of the arrows.

Figure 3 is a sectional view taken on the line 3-4 of Figure 1 looking in the direction of the arrows.

Figure 4 is a fragmentary vertical longitudinal sectional view showing in detail the lock per se.

Figure 5 is a perspective view of the striking element of the assembly.

Figure 6 is a fragmentary sectional view similar to Figure 1 showing a slight modification.

Figure 7 is a sectional view taken on the line of Figure 6 looking in the direction of the arrows.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, particularly Figures 1 to 5, inclusive, A designates generally a portion of a motor vehicle door, being constructed from sheet metal and of hollow type while in the outer side IU of this door A is a depression accommodating an outside handle |2 while journaled in the inner side l3 of said door is the inside handle |4 of such door. The handle I2 is of the loop type, as at [5, while the handle I4 is of the crank type.

The handle M at its stud journal I6 is formed with a throw arm having pin and slot connections at l8 to a link l9 which has universal connection at 20 with a spring-projected latching bolt 2| adapted as is usual to engage a keeper in the door frame for the fastening of the door A in a closed position. This bolt is accommodated within a housing 22 built within the hollow of the door A and is formed with a shoulder 23 against which is seated a coiled expansion spring 24, the latter being also seated against the housing 22. This spring 24 functions to move the bolt to latching position yet allowing retraction of the bolt on the turning of the crank handle M or the operation of the handle I2, respectively.

The handle I2 is swingable in a horizontal direction or at right angles to the outer side of the door ID on a pivot 25 for said handle and this pivot is supported in a bearing bracket 26 fixedly secured in the hollow of the door A at the proper point for the successful operation of said handle. The handle |2 in the operation thereof is partially accommodated within the depression I I constituting a seat therefor and its loop I5 is disposed for hand gripping thereof.

The handle I2 is provided with a kicking nose 21 engageable with a striker pin 28 on a rocking member 29, which is journaled within the hollow A of the door and disposed crosswise with relation to the throw bolt 2|, the journaling of said member 29 being had in the outer and inner sides H) and I3 of said door A. This member 29 is provided with a kicking lug 30 engageable with an abutment 3| on the bolt 2|. Thus when the handle I2 is swung outwardly away from the door A, its nose 21 engages with the striker pin 28 rocking the member 29 and the lug 30 acts upon the abutment 3| retracting the bolt 2| against the resistance of the spring 24 and in this way the door is unlatched. This bolt 2| can be retracted by turning the crank handle l4, as should be clearly apparent from Figure 1 of the drawing. 55

' locking bolt 35 and this bolt engages with the handle l2, being guided through openings 36 and 3! in the bearing bracket 26 and the said handle l2, respectively, so that the handle II! will be locked against movement.

The locking bolt 35 is released on the operation of the lock 32 by a key (not shown) in the conventional manner. The-bolt 35 is thrown by the arm 33 both to locking and unlocking positions with relation to the handle I2 and is held in its extreme position through tumbler action of the cylinder lock.

In Figures 6 and 7 of the drawing there is shown a modification of the invention wherein the latching bolt 38 is formed with a lug 39 having a depressed tracking surface Gil for a ball terminal 4| of a bell crank end 42 on the outside operating handle 33 so that when this handle is swung in one direction the bolt 33 will move to unlatching position.

The bearing bracket 26 carries a leaf spring M against which plays a pin carried by the handle [2 and this spring functions to retract the handle l2 into the seat II in the outer side ll] of the door A. The bearing bracket 45 for the handle 43 carries a leaf spring l! engaging the pin 48. The spring 41 functions in the same manner as the spring 44.

The bolt 35 is guided in its movement by a guide 49 secured interiorly of the door A.

The operation of the door handle and lock assembly is thought to be clearly obvious from the foregoing taken in connection with the accompanying drawing and of course it is understood that changes, modifications and variations are contemplated as fall properly within the scope of the appended claims.

What is claimed is:

1. A handle and lock assembly for a door having a recess in one face of said door, comprising a spring-projected latching bolt slidably fitting said door and having an abutment, a rocking member disposed within the door crosswise with relation to said bolt and having striker pin and kicking lug projections, respectively, thereon, the kicking lug being arranged for engagement with the said abutment, a lever constituting a handle fitting said recess and pivotally supported therein, a noselike cam formed on said lever and active upon the striker pin for the turning of the rocking member and activation of the kicking lug to eiTect retracting of the projected bolt on outward swinging of the said lever, a pin fixed to the lever remote from the nose, and a leaf spring fixed within the door next to said last-mentioned pin for overriding the latter and holding the lever seated within the recess.

2. A handle and lock assembly for a door having a recess in one face of said door, comprising a spring-projected latching bolt slidably fitting said door and having an abutment, a rocking member disposed within the door crosswise with relation to said bolt and having striker pin and kicking lug projections, respectively, thereon, the kicking lug being arranged for engagement with the said abutment, a lever constituting a handle fitting said recess and pivotally supported therein, a noselike cam formed on said lever and active upon the striker pin for the turning of the rocking member and activation of the kicking lug to effect retracting of the projected bolt on outward swinging of the said lever, a pin fixed to the lever remote from the nose, a leaf spring fixed within the door next to said last-mentioned pin for overriding the latter and holding the lever seated within the recess, a locking bolt slidably engageable with the said lever for holding the same fast in seated position within the recess, and a key-operated cylinder lock fitting said door and having a turn barrel connection with the locking bolt for moving the same to locking and unlocking positions.
