7 Claims.

hinges and usually terminates in quite a sharp The or substantially vertical curve at its rear. deck lid when closed presses down upon, and is sealed completely around its periphery by a rubber Weatherstrip. Due to the fact that the deck lid is a thin sheet steel stamping having the above described curvature, the lid tends to crinkle if not provided with the correct lock.

It is the object of this invention to produce a simple deck lid lock which will draw the lid.

into sealing relation with the Weatherstrip and place the lid under tension rather than compression and thereby avoid crinkling of the lid when locked.

Figs. 12 and 13 are detail views of a slightly modified form of lock.

Referring more particularly to the drawings,

there is shown a portion of the rear deck of an automobile body comprising outside sheet metal panel I and inner sheet metal panel 2. The lid is provided with an overlap flange 3 (Fig. 8) which presses and seals against a rubber weatherstrip 4 which extends completely about the periphery of the opening in the rear deck 5. Figs. 8 through 11 show the lower horizontal edge of clockwise, Fig. 7, thereby drawing links 30 lip-- the deck lid, that is, the end most remote from the front edge, not shown, which is hinged to the body.

The deck lid locking arrangement comprises a pair of locks operated by a single deck lid handle Ii. Only one look will be described because the two locks are identical. The lock comprises a support plate 8 which is fixed to the inner panel 2 in any suitable manner, such as by welding or bolts. The plate 8 has a vertical flange I which projects outwardly from the inner panel 2, as. shown in Fig. 2.

The latch bolt is designated 9 and the bolt head takes the form of a hook Ill. The bolt 9 is positioned between the legs II and I2 of the yoke I3 and pivoted on pin I4 which is fixed to legs II and I2. A pin 22 is journaled in flange I. Yoke I3is fixed to pin 22 on one side of the flange l and lever 23 is fixed to the yoke on the other side of the flange. The bolt is biased downwardly by spring I5 carried on pin I4, the lower end I6 of which hooks over bolt 9. The bolt 9 is provided with lug I! which abuts corner I8 of flange I to limit the downward swinging oi bolt 9 when the lid is raised and the bolt head It! disconnected from its keeper I9. The keeper I9 is fixed to bracket .20 which is fixed to the rear deck panel 5 adjacent the lower edge of the rear deck opening 2I.

The swinging of each bolt is effected by rotation of handle 6. Handle 6 is journaled in a bracket 24 fixed to the inside lid panel 2. A lever 25 is fixed on the handle spindle 26. A pair of links 2'! connect the lever 25 with levers 28 which are pivotally mounted on plate I by means of pins 29. Link 30 connects lever 28 with lever 23.

In Figs. 1 and 8 the lock is shown in locked position with the bolt head I!) interengaged with keeper I9. 7 To open the lid the handle 6 is turned so that lever 25 rotates counterclockwise, Fig. 1. The push thus exerted on links 21 causes the lever 28 on each lock to swing clockwise, Fig.

3, which, through link 30, swings lever 23 counterclockwise as viewed in Fig. 4. This causes yoke I3 to swing counterclockwise, Fig. 4, whereupon the yoke strikes the tail 32 of bolt 9 causing it to rotate counterclockwise and disengage the bolt head I0 from the striker as shown in Fig. 9.

The locking of the lid is effected as follows: The lid is closed until it rests against the eatherstrip 4. At this time the lid is usually not completely closed as ilustrated in Fig, 10. The position of the handle and lever 25 is illustrated in Fig. 7. To lock the lid the handle 6 is rotated so that the lever 25 rotates clockwise, Fig. '7, thus pulling on links 21 which turn levers 28 wardly. As link 30 is drawn upwardly yoke I3 rotates about pivot 22 clockwise, as viewed in Fig. 10, thus raising pivot I4, the point at which bolt 9 is connected to yoke I3. At this time, as shown in Fig. 10, pivot 22 is positioned above pivot I4. .As pivot I4 rotates clockwise about fixed pivot 22, bolt 9 is drawn toward the left and upwardly, Fig. 10, which causes the bolt head I I] to swing downwardly into engagement with the keeper I9, as shown in Fig. 11. Further rotation of yoke I3 causes the lid Ito be pulled first inwardly until pivot point HI is on the same level as pin 22, Fig. 11, whereupon further clockwise rotation of yoke l3 causes the lid I to be drawn downwardly into tight engagement with the Weatherstrip 4, as shown in Fig. 8. It should be noted that after the hook l engages striker I9 that bolt 9 rotates about pin l4 relative to yoke I3. In final locked position pivot point I4 is over the center line passing through the center of pivot 22 and the point at which bolt head l0 contacts striker 35, see Figs. 5 and 8. Due to this over center locking arrangement any attempt to force the lid I open merely tends to rotate yoke I3 clockwise, Fig. 8, thus tightening the interengagement between the bolt head and the striker. The bolt can only be disengaged from the keeper l9 by rotating yoke l3 counterclockwise, Fig. 8, to again bring pivot M to the left of center, that is, a line passing through pin 22 and the point at which the bolt head It interengages the striker, as illustrated in Fig. 8.

In the modified form shown in Figs. 12 and 13 there is provided a simplified form of connection between the levers 23 and the yoke l3. In this form of the invention the support plate 48, corresponding to plate I, is provided with a flange 4|. Pin 42 is riveted at one end to flange 4| and carries a bushing 43. Yoke I3 is rotatably supported on the outer end of pin 42. Pivot 42 corresponds to pivot 22 of the principal form of the invention. Link 44, corresponding to link 39, is pivotally connected at one end to lever 28' and the It will be noted that when the bolt head I0 is interengaged with the keeper I?! that the bolt 9 swings about the keeper [9 as a center during the final locking movement of the bolt and during the initial opening movement of the bolt.
