ABSTRACT OF THE DISCLOSURE
An improved deck lid lock with remote release for motor vehicles. The deck lid lock employs a solenoid operated rotatable armature which acts directly on a leg of a rotatable latch plate which engages a lock bar. On energization of the solenoid, the armature is attracted to the solenoid causing it to disengage the latch plate so that the deck lid may be opened. When the deck lid is closed, the lock bar is engaged by the latch plate which is returned to its normal latched position in engagement with the armature. The deck lid lock further includes a rotatable key cam which acts on the armature to enable release of the deck lid through conventional external key actuation.

TRUNK LID LOCK WITH RE.IOTr RELEASE
BACKGROUND AND SU~RY OF THE I~rvE~Io~
This invention relates to a remote mechanical release mechanism and particularly to one adapted for reieasing the deck (i.e. trunk) lid of a passenger car motor vehicle.
As a convenience feature, motor vehicle manufacturers often equip their products wit~ remote release mechanisms for the vehicle's trunX lid. This feature enables the trunk lid to be released from inside the passenger compartment so that the driver does not have to remove the keys from the ignition and exit the vehicle to unlatch the deck lid externally. Various designs for such devices are presently known. Althougn remote release ~echanisms according to the prior art perform satisfactorily, there is a continuin~
desire to reduce their oomplexity, size and cost, while providing acceptable operating and durability characteristics.
In accordance with the present invention, an improved deck lid lock with remote release is provided which is compact and has very few moving parts as compared with many designs according to the prior art. The simplicity of the subject device is achieved, in part, through combining the functions of a solenoid armature and a release latch element into a single multifunctional component.
Additional benefits and advantages of the present invention will become apparent to those skilled in the art to which this invention relates from the subsequent 1, ~e - ~ 3 ~
description of the preferred em~odi~Qnts and the appended claims taken in conjunction with the accompanying drawings.

Figure 2 is a side-elevational view of an improved deck lid lock with remote release according to the present invention which is partially cut away showing the various internal co~ponents thereof.

, DETAILED DESCRIPTION OF THE I~ .NTIo~
Figure 1 illustrates a deck lid lock with remote release according to a prior art design which is designated by reference number 10. Lock 10 is illustrated herein to provide a background for describing the advantages of the design according to the present invention. Lock lO includes base plat~e 12 which supports the re~aining components of the lock. Base plate 12 is mounted to either the deck lid or the vehicle body! depending on the particular application.
Solenoid assem~ly 14 includes a longitudinally movable armature 16 having a radially flared head 1~. Spring 2Q
biases armature 16 to the extended position as shown in - 13~7~ 1 E'igure 1. In accordance with conventional design practices, the application of current to windings 22 of solenoid assembly 14 causes armature 16 to be attracted to pole piece 24, and overcomes the biasing force applied by spring 20.
Latch dog 26 is rotata~le about pin 28 and includes arm 30 which is engaged by head 18 upon retraction o~ armature 16.
Latch dog 26 further includes hook-shaped arm 32 and arm 34.
Deck lid lock latch plate 36 is rotatable about pin 38 and includes an elongated arm 40 which engages the hooked portion of latch dog arm 32, as shown in Figure l, and also includes notch 42 which engages lock bar 44 affixed to the vehicle decX lid (or the vehicle rear compartment structure). Key cam 46 is journaled for rotation within base plate 12 and includes a central slot 48 which receives a similarly shaped bar which extends from the deck lid lock cylinder (not shown). Key cam 46 includes a projecting cam tab 50 which acts on latch dog arm 34 when key cam 46 is rotated clockwise from the position shown in -Figure l.
Torsion spring 52 is wrapped around pin 38 and has ends engaging latch plate 36 and latch dog 26, urgin,g both of them to rotate in a counterclockwise direction.
Figure 1 illustrates the orientation and cooperation of the elements of lock 10 when the deck lid is in a closed and locked condition. Latch plate 36 is maintain~d in the position shown through engagement between latch plate arm 40 and latch dog arm 3~. When it is desired to releas2 the deck lid remotely, voltage is applied to ;conductors ~ 3~ 8 t~3 communicating with winding 22 thus energizing the solenoid and causing armature 16 to be retracted. This movement causes engagement between head 18 and latch dog arm 30, urging latch dog 26 to rotate in a clockwise direction.
This motion releases latch plate arm 40 enabling it to rotate in a counterclockwise direction until lock bar 44 is released, and thus enabling the deck lid to be opéned. -When the deck lid is closed, lock bar 44 acts on latchpl~te 36 causing arm 40 to re-engage latch dog arm 32, thus returning the components to the orientation shown in Figure 1. When the user releases the deck lid externally using a ~ey, key cam 46 is rotated which causes cam tab 50 to engage latch dog arm 34 which in turn causes latch dog 26 to rotate clockwise, thus releasing latch plate 36, as previousIy explained.
Figure 1 further illustrates additional components which are conventionally provided with deck lid-lock 10, such as electrical connector 54 enabling convenient connection to the vehicle wiring harness~ Lock condition s~iitch 56 is used to provide a warning that the deck lid is in a released condition which is indicated through contact between an-element of the switch and latch plate 36 when the plate is rotated to its counterclockwise (released) position.
Now with reference to Figures 2 through 4, an improved deck lid lock with remote release according to the present invention is shown which is generally designate~ by 13~7~3 reference number 60. Lock lO may be affixed to the vehicle~s rear compartment structure to engage lock bar 44 attached to the deck lid, or the positioning of these components may be reversed, depending on the application.
Deck lid lock 60 includes base plate 6Z which ~orms a structural support ~or the remaining components o~ the lock.
Solenoid 63 includes windinys 64 which surrounds pole piece 66 which is rigidly affixed to base plate 62~ ;
Armature 68 is pivotable about pivot axis 69 defined by projecting tabs 70 and 71, and is movabl fxom its normal position shown in Figure 2, to a counterclockwise displaced release position. Armature 68 includes a pair of legs 72 and 74 which are disposed about opposite sides of the pivot axis 69. Legs 72 and 74 are designed such that they provide a center of gravity location for armature 68 which is at or near axis 69. This balancing renders lock 60 relatively insensitive to inertial inputs which has been ~ound to produce inadvertent lock release in some lock designs. Ieg 72 de~ines.dimple 76 which cooperates with pole piece 66 to define a tapered working air gap. Armature leg 74 defines engaging edge 80 and spring engaging notch ~2.
Latch plate 86 is rotatable about pin 88 between the normal engaged position shown in full lines in Figure 2, and the released position shown in phantom lines. Latch plate 86 has a pair of legs 90 and 92 de~ining notch 94 which traps lock bar 44, as ~reviously explained in con~unction with the prior art structure shown in Figure l. Arm 96 ~31 , engages armature engaging edge ~o ~.~en ar-lature 68 is in the position shown in Figure 2. Energy absorber 97 is made from an elastomer and is carrie~ by latch plate arm 96 and contacts the side surface o base plate 62 when the arm moves at high velocity fro~ the phanto~ line position to the full line position. Torsion spring 98 has extending arms 99 and 101 which engage base plate 62 and latch -plate 86 respectively to bias the latch plate in the countercloc~wise direction about pin 88. Latch plate ar~ 96 de~ines a lower notch 102 engagable with armature engaging edge 80.
Key cam 106 is journaled for rotation within base plate 62 and includes a radially p.oj~cting cam tab 10~ and rectangularly-shaped slot 110 which engages a similarly shaped rod extending from the trunk lid lock cylinder (not shown). Torsion spring 112 wraps around key cam 106 and engages the key cam at end 11~. Spring end 116 projects into and engages spring engaging no,ch 82, thus biasing key cam 106 in a counterclockwise direction and armature 68 in a clockwise direction. . f Figure 2 illustrates (in the full-line position of latch plate 86) the orientation and cooperation of elements when the.deck lid is closed and loc~ed. In that condition, latch plate 86 engages lock bar 44 and is maintained in the position shown through engagement between latch plate notch 102 and armature engaging edge 80. When it is desired to release the deck lid remo~ely, voltage is applied to windings coil 64, causing armature 68 to be attracted toward 13~7~ 1 pole piece 66. This attraction causes armature 68 to overcome the biasing force applied by spring ~12, thus moving the armature to its counterc ockwise position~ Upon this movement of armature 68, it becomes disengaged from latch plate arm 96, enabling the arm to rotate in a counterclockwise direction in response to the biasing applied by spring 98. When latch plate 86 reaches the phantom-line position shown in ~igure 2, lock bar 44 is released which enables the deck lid to be opened.
Release o~ the deck lid through external actuation of the latch cylinder causes key cam 106 to rotate in a clockwise direction such that cam tab 108 acts directly on armature 68, moving it coun.erclockwise to a position to release latch plate arm 96.
When the deck lid is closed, do~nward motion of lock bar 44 acts on latch plate legs 90 and 92, urging latch plate 86 to rotate in a clockwise direction. When latch plate arm 96 engages the upper surface of leg 74, the armature i5 moved counterclockwise against the .urging of l spring 112. Continued rotation causes latch platelnotch 102 to engage armature engaging edge 80 causing the armature to return to the full-line position sho~n in Figure 2. Energy absorber 97 serves to reduce the rebound velocity of arm 96 when it reaches its extreme clockwise position ~o ensure proper engagemen~ with armature edge 80.
As is evident from the appended figures and above description, deck lid lock 60 is less complex and has fewer 13~7~
.
components than deck lid lock 10. This reduction in complexity is achieved primarily through the elimination of a separate latch dog element 26 shown in Pigure l. Instead, armature 68 shown in Figure 2 performs the functions of both latch dog 26 and armature 16 of the prior art structure shown in Figure 1.
Deck lid lock 60 is very compact which is attributable to the dual function operation of armature 68 and du~ to the positioning of solenoid 63. Latch plate arm 96 is of a length dictated by the force output of solenoid 63, since the frictional engagement between armature edge 80 and latch plate notch 102 which must be overcome by the solenoid decreases with the length of the arm. Given that the arm 96 establishes a minimum size of lock 60, solenoid 63 is efficientl~ packaged adjacent latch plate 86 and on the same side of armature 89 as the latch plate.
While the above description constitutes the preferred embodiments of the present invention, it will be appreciated that the invention is susceptible to modification, variation and change without departing from the proper scope and fair meaning of the accompanying claims.
