Truhon, Detroit, Mich., assignor to Theodore Bargman Co., Detroit, Mich., a corporation of Michigan Filed Nov. 6, 1961, Ser. No. 150,511 10 Claims. (Cl. 70-146) This invention relates to a door lock and more specifically to a dead bolt mechanism for a door look.
.It is an object of this invention to provide a door lock with a dead bolt mechanism of simple construction and very effective in its action to lock the latch bolt lot the lock in the projected, keeper engaging position.
A further object of the invention is to provide a dead lbolt mechanism for a door lock which is designed such 7 with a dead lbolt mechanism'in the unlocked condition.
FIG. 4 is a fragmentary elevational viewof the out- ;siderlock operating knob- FIG. 5 is a fragmentary view similar to FIG. 3 with the dead bolt mechanism in the locked condition. 1 ll cIG. 6 is an exploded perspective view of the door FIG. 7 is a fragmentary elevational view of the inside handle operating mechanism with the dead bolt mechanism in the unlocked condition.

p, FIG. 9 is a view similar to FIG. 7 with the dead bolt mechanism in the ,locked condition.
FIG.v 10 is a view similar to FIG. 8 with the dead .bolt mechanism in the locked condition.
\FIG. 11 is a fragmentary plan view of the latch assembly for the dead bolt mechanism.
FIG. 12 is a sectional view along the line 12-12 in FIG. 11.
, Experience has shown that many door locks are provided with dead bolt. mechanisms which aresusceptible to being accidentally actuated to either the locked or the unlocked condition upon slamming the door shut.
This is particularly true of door locks which are presentr 1y being installed on the outside doors .of mobile homes. Such a mobile home is shown at 10 in FIG. 1. outside or the access door is indicated at 12 and the door lock therefor is indicated at 14. The door 14 is mortised as at 16 to receive the lock and the door frame,
as is conventional, is mortised as at 18 for accommodating a keeper 20 with which the latch bolt 22 of the door lock is engageable to retain the door in the closed position. The door lock of this invention includes an outside plate 24 on which is journalled a spindle 26 to which an outside knob 28 is aflixed. The inside plate 30 journals a spindle 32 to which an inside operating handle 34 is afiixed. On the inner side thereof, outside plate 24 has a pair of threaded sockets 36 adapted to receive screws 38 extending through the inside plate 30 to secure the two handle assemblies on the opposite faces of door 14.
The latch bolt 22 is slideably retained for reciprocation in a guide plate 40. Latch bolt 22 has a U-shaped portion 42, the free ends of the legs thereof being fashioned with projecting lugs 44. Springs 46 hearing against the ends of the legs of the U-shaped portion 42 normally bias bolt 22 outwardly to the projected position. Bolt 22 is retained on guide plate 40 by means of a cover plate 48. Guide plate 40 with its cover plate 48 is secured to the outside plate 24 by means of four screws 50 which extend through registering apertures 52, cover plate 48 and guide plate 40. Screws 50 thread into upstanding sockets 54 formed on the inner face of outside plate 24.
Within the outside spindle 26, there is arranged a keyoperated lock cylinder 72 provided with a radially extending pin 74 at its inner end. Pin 74 projects through an arcuate slot 76 in spindle 26. Pin 74 is designed to shift slide 64 in opposite directions in the guideway formed by ribs 62 by engaging the abutments 80, 82 at the periphery of opening 66 in slide'64. When the lock cylinder 72 is actuated in the unlocking direction of rotation, pin 74 engages abutment 80 to shift slide 64 in a direction to the left as viewed in FIG; 8 and when the lock cylinder is rotated in the locking direction, then pin 74 engages abutment 82 to shift slide 64 in a direction towards the right as viewed in FIG. 8. One of the ribs 62 on the outside plate 24 is provided with a pair of notches 84, 86 in which a spring biased bearing ball 88 is adapted to seat for yieldingly retaining the slide 64 in either of its two extneme positions of reciprocation (FIG. 8).
It will be noted that the lugs 44 on bolt 22 project through a pair of elongated slots 89 on cover plate 48.
. It will also be observed that cam 61 is fashioned with The' a shoulder 90 and cam 63 is fashioned with a pair of arms 92. When the inside door handle 34 is pivoted downwardly or in the clockwise direction as viewed in FIGS. 7 and 9, shoulder 90 engages the upper lug 44 of the latch bolt to retract the bolt and likewise, when the outside knob 28 is rotated in either one direction or the other, the arms 92 engage the lugs 44 to retract the bolt 22.
Referring now to FIGS. 2, 3 8 and 10, it will be noted that the face of slide 64 adjacent the cam 63 is fashioned with a pair of circular stud portions 94, 96. These stud portions are disposed on diametrically opposite sides of cam 63. Cam 63 is fashioned with a notch 98 in its outer periphery which, in the normal position of the camis radially aligned with stud 94. When slide 64 is shifted to the right as viewed in FIGS. 8 and 10 by actuating the lock cylinder, stud 94 is shifted into notch 98 to thereby prevent rotation of cam 63. In this position of slide 64, the outside knob 28 is effectively prevented from being rotated and thus, the bolt 22 is prevented from being retracted by cam 63. It will also be noted that the stud 94 together with the action of the spring biased bearing ball 88 in the notch 86 effectively locks cam 63 against rotation.
Referring now to FIGS. 6, 11 and 12, it will be noted that a latch assembly 100 is pivotally supported on cover plate 48. Latch assembly 100 includes a hinge plate 102 fixedly secured to cover plate 48 as by rivets 104, a latch member 106 having ears 108 at one end hooked behind the reversely bent hooks 1-10 of hinge plate 102 and a leaf spring 112. Cover plate 48 is suitably apertured as at 114 to accomodate latch 106 and the reversely bent hooks 110 of hinge plate 102. Latch 106 is formed with a shoulder 116 adjacent the free end thereof and with a cam projection 118 at the central portion thereof. Cam projection 118 extends from the plane of latch 106 in the direction towards slide 64. The stud 96 is located on slide 64 such that when the slide is shifted to the locked position, post 96 engages cam projection 118 to pivot latch 106 toward bolt 22 to a position wherein shoulder 116 engages behind the bight section 120 of the U-shaped portion of the bolt to prevent retraction of the bolt as is illustrated in FIG. 9.
