Abstract
979,162. Remotely controlled fastenings; latches. TRICO PRODUCTS CORPORATION. Feb. 23, 1961 [Feb. 25, 1960], No. 6683/61. Heading E2A. A valve assembly for operating a door locking motor 41 to lock a vehicle door automatically when the vehicle engine is started comprises a housing 19 which is divided internally into two chambers 18, 49 by a diaphragm 23, a spring 24 urging the diaphragm in one direction, a port in the housing through which communication can be made with a fluid source 14 generated when the vehicle is started, to move the diaphragm against the action of the spring, a valve 28 connected to the diaphragm 23 so as to be opened when the diaphragm is moved against the action of the spring, to establish communication between a motor-operating fluid source 14 and an outlet port to be connected to the motor during use to lock the vehicle door, and including metering means 51-53 providing for restricted communication between the two chambers whereby the pressures in the two chambers equalise after a while so as to permit the spring to close the valve and including also a manual control valve 71 whereby the motor-operating fluid source can be connected to the outlet port independently of the operation of the diaphragmcontrolled valve 28. As shown, the intake manifold 12 of an automobile engine is connected through a conduit 13 to a vacuum tank 14 which includes a spring-loaded check valve 15. The manifold is also connected through a conduit 22 and a driver's seat-valve 21 with the housing 19. When the vehicle engine is started, chamber 18 is evacuated and the diaphragm 23 lifts the valve 28 to connect chamber 18 with a chamber 29 which is thereby also evacuated and effects lifting of a valve 37 to connect a chamber 40 of a door locking motor 41 associated with each door lock 54 to the reservoir tank 14 through conduits 42-46. Evacuation of chamber 40 flexes a diaphragm 47 which effects movement of a rod 48 connected to a door latch 54. The metered connection 51, 52 established between chambers 18 and 49 comprises a conduit 52 and an adjustable filter screw 53, so that after a time determined by the setting of screw 53, both chambers 18 and 49 become fully evacuated and diaphragm 23 is restored to its original position by its spring 24, and valve 28 is closed. Chamber 40 is then vented to atmosphere through chamber 44 and filter 56 in valve chamber 29 as valve 37 is restored to its original position. Manual operation of lock 54 is not affected. The seat valve 21 prevents operation of valve 19 unless the driver's seat is occupied. Each door lock comprises a rotor type latch bolt 80<SP>1</SP> having a ratchet wheel 87<SP>1</SP> on the shaft thereof which is engageable by a lever 83<SP>1</SP>, to retain the latch bolt in fastened position and is locked in that position against operation by an outside push button 76<SP>11</SP>, by a sill button 59<SP>1</SP> or by the motor 41. The latch may be released however by an inside handle through linkage 101-103. All doors may be locked or unlocked from within the vehicle by means of the manual remote control valve 71 having a pivoted knob 70 which when moved from a central position in one direction effects communication between the reservoir 14 and the chambers 40 of motors 41 and which when moved to the opposite direction effects communication between the reservoir 14 and chambers 88 of the motors 41, respectively. Specification 907,003 is referred to.
