9 Claims.
` This invention relatesto a door lock and more particularly a door lock for an automobilev door.
It is an object of this invention to produce a lock which permits the use of a narrowdoor lock pillar. This objectis achieved by arranging the bolt so that it is retracted by power stored up during the opening of the door thereby obviating the need for the usual outsidedoor handle spindle which cuts across the door and through the pillar outside the path of travel of the sliding window glass. j
AIt is also an object of this invention to produce an automobile door lock which can be easily operated from without the door by a flush door handle or push button'thereby obviating the need for. the conventional swinging handlewhich projects from the outside face of the door.
In the drawings:` i H Fig. 1 is a fragmentary view of the outside face of an automobile door and the adjacent hinge pillar with a detail showing of the lock.
Fig. 1 is a fragmentary View showing the lock bolt, striker and outside door handle.
Fig. 2 is a section along the line 2-2 of Fig. 1.
Fig. 3 is a section along the line 3-3 of Fig. 1.
Fig, 4 is a view along the line 4-4 of Fig. 1'.
Fig. 5 is a detail showing connections between the outside handle and the toggle.
Referring more particularly to the drawings there is shown a door I hingedat its forward edge to the body hinge pillar `2. In Fig. 1 the outside door panel i3 has been broken away to show the lock in elevation;
'I'he lock comprises a bolt 4 .arranged to interengage striker 5 mounted onr the body pillar 6. The bolt is retracted by a draft link 1 having a lost motion connection with the bolt 4 in theform of a pin 8 xed to the bolt which engages link 1 in the elongated slot 9.` i
The remote end of the link 1 is pivotally connected by pin I with lever II. The leverv I Iis pivotally mounted on plate I2 by pinrl3. The upper end of lever II is pivotally connected Aby pin III to plate I5' which is hinged by means of pin I to toggle link I1. Toggle link I1 is hinged by means of pin I9 with toggle lever I8. Toggle lever I8 is hinged by pin 20 to plate 2| which is fixed by means of rivetv22 to the inner sheet metal door panel 23. Toggle I1, I8 .is biased Ato over center position by spring` 24 carried on pin IB. Toggle I1, I8 is broken byV push button 25 acting against pin I9. Push button 25 -is held vin retracted position by Vcoil. spring 2.6.' Y `A. convolute spring `A21;V is fixed4 to plater|2 as at 28 `and has its free end 29 hooked over-stud 30 (c1. zee-164) on link 1. It is proposed to energize or load coil spring 21 during the initial opening movement of the door I. To this end a slide plate 3| is slidably `mounted along the lower edge of plate I 2 and guided along its side faces by plates 33 and 34 which are welded or otherwise .xed to the lower' edge of plate I2. The slide 3| is yieldably held against the lower edge 32 of plate I2 by tension coil spring 35 which has its upper end 36 hooked into bracket 31 turned out of plate I2 and its lower end 38 hooked into lug 39 fixed to slide 3|.
The operation of this lock is as follows: As Shown in the full lines in Figs. 1, 2 and 5, the bolt is projected, the toggle I1, I8 made, thereby acting through lever |I and pin 30 tohold the spring 21 in compression. To retract the bolt the push button 25 is pushed in to break the toggle I1, I8, dotted line showing Fig. 2. This releases link 1 so that the spring 21 is free to unwind thereby moving link 1 and lever II to the left, dottedline showing Fig. 1, which retracts the bolt. It will be noted that when the bolt is retracted and the door closed, the rounded lower corner of lever I I is positioned against shoulder 4I of slide 3|. As the door opens, slide 3| moves to the left relative to plate I 2, as viewed in Fig. 1. As the slide 3| moves to the left, shoulder 4I engages toe 40 thereby swinging lever Il clockwise, which moves link 1 and bolt 4 to projected position and at the same time energizes or compresses spring '21. As the lever II moves clockwise, it also returns the toggle I1, I8 to made position which holds the lever |I in its original position until again released through push button 25. This' action occurs during the initial opening movement of the door. As the door is swung further open to fully open position the rounded toe 40 o f the lever slides along the top edge 32 of slide 3| until the rubber bumper 42 abuts the door hinge pillar 43 checking further opening of the door. y As the Vdoor swings closed, rounded toe 4I] of the lever |I slides back over the upper edge 32 of slide 3| and bolt 4 rides over and interengages striker 5.
It will be noted that afterthe door has been swung open suiciently to swing lever I I clockwise to stress spring 21 and make toggle lever I1, "I8, which is hereinafter referred to as the set position of lever I I, that upon'further opening of the door rounded toe 40 slides along upper edge l32 -offslider3|. Because of this, after the lever I is set Vit cannotbe released and the bolt retracted until the door is again swung nearlyclosed, that is, until the rounded toe 40 of the lever again passes to the left of shoulder 4l, Fig. 1.
The bolt 4 is projected by the conventional convolute spring 55). To retract the door from the outside, the outside handle 5l, pivoted as at 52, is swung outwardly which draws the draft link 53 in the direction of the arrow (see Fig. 5). The draft link 53 swings the bell crank 54 counterclockwise, Fig. V5, thus mloving the pin I9 and the toggle Il, I8 outwardly past center to break the same. This releases the energy stored in spring 21 which retracts the bolt 4. 2l is stronger than spring 50 so that as the bolt l is retracted, spring 50 is loaded or wound up.
The door is provided with a pivoted pane156 and a sliding panel 51, such as described in the Fisher Patent No. 2,048,605. The link 53 Will be located on the outside of the sliding panel 5l and will connect with the bell crank 54 beneath the pivoted panel 56.
