Application May 4, 1942, Serial No. 441,612
3 Claims. (Cl. 121-44) 3 I This invention relates to closure operators and is directed especially to. a fluid operated window system for motor vehicles.
It has heretofore been proposed to open-and close the windows of automobiles by fluid pressure, utilizing the intake manifold of the power plant as a source of operating pressure. In such installation the fluid motor is usually concealed within the confined quarters found in the lower portion of the hollow door .of the vehicle. Consequently, the air conduits must be arranged to the best advantage so as to dispose the operating control toward the upper portion of the door to be accessible to the motorist. This has necessitated rather long tubes leading between the operating control and the motor which tended to delay the responsiveness of the motor.
The present invention has for an object to pro- Q vide a window or closure system which is practical and readily adapted for installation within the door compartment. Further, the invention has for its aim to provide an all-fluid remote control for the motor by which the motor operating unit may be located in proximity to the fluid motor while a more distant operating control may be arranged in a position accessible to the motorist. The invention chiefly has for its object to provide an all-fluid window system which is efficient in operation and easily installedin that a single power line only is required to be brought over into the door.
In the drawings:
Fig. 1 is a diagrammatic view of an automobile door equipped with the window operator of the present invention; a
Fig. 2 is a front elevation of the remote motor operating unit Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 2 through the motor operating unit, parts being left in elevation;
Fig. 4 is a rear elevation of the unit;
Fig. 6 is a detailed sectional view of the selector accessible to the motorist. v
Referring more particularly to the drawing, the numeral i designates the window panel slidable in the guideways 2 and carrying on its bottom edge a bracket 3 in which the arm 4 of the bell crank lever is slidably engaged, the lever being pivoted at 5 and having its power arm 6 pivotally connected by a piston rod 1 to the piston 8 of a fluid motor. The motor chamber 9, at the opposite sides of the piston, is connected by the branch conduits llland I l to themotor operating unit l2 located adjacent the fluid motor and in turn connected to the pressure supply line l3, leading to a source of pressure, such as the intake manifold of the vehicle engine. For selectively actuating the operating unit to open or close the window, valves H are provided in a position readily accessible to the motorist, being connected by conduits l5 to the unit 12.
The motor control valve unit comprises a body having a pair of vacuum chambers I1 and I8, ar-' ranged side by side and opening through ports l9 and 20 into the pressure supply passage 21. The body also has a pair of atmospheric chambers 22 and 23 which are correspondingly related to the vacuum chambers, one for each. A motor passage 24 opens through seats 25 and 26 into one of the vacuum chambers and its associated atmospheric chamber, respectively, and a like motor passage 21 opens through seats 28 and 29 into the other vacuum chamber and its atmospheric chamber, respectively, the two motor passages being joined by conduits l0 and II to the motor. A valve 30 is normally held engaged with the seat 23 by an underlyin spring 3|, while a similar valve 32 i normally held engaged with the seat 28 by a spring 33. The vacuum chambers l1 and I8 are designed to receive the pistonlike valves 34 and 35 for engaging the seats 25 and 28, such valves preferably being slidably mounted and sealed against air leakage by packing flanges 35 and 31, respectively. The seats of each pair are preferably in axial alinement and at the opposite ends of a passage through a partition wall so that the valves may be joined by a simple interposed spacer rod 33 whereby the seat- :ing of one valve will effect an unseating of the connected valve.
The vacuum chambers at the remote or upper side of the piston valves are connected by nipples 39 and 40 to the conduits l5 leading to the selector valves l4. the arrangement being such that as one or the other of the selector valves I4 is depressed to vent its conduit l5 to the atmosphere,
- motor operation this air flow may be throttled or determined, as by a rotary disc valve 42 engaging on a perforated closure wall or seat 43. The valve and seat are formed with registrable openlugs 44 and are pivotally connected by a pin 45. An operating handle ll extends from the valve disc so that the registrable ports may be brought more or less out of full registry to throttle the air flow into the atmospheric chamber. When installed, these handles may be rendered accessible by suitable means such as the slots I! in the finishing panel 48 of the door. The fllter pad may be secured in place by a foraminous retaining frame 49.
In the operation of the system, both ends of the fluid motor chamber are normally incommunication with the suction source and when either selector valve is actuated to vent the connected upper end of the corresponding vacuum chamber the higher pressure will cause the piston valve to seat, for interrupting the suction communication, and the atmospheric valve to unseat whereby the atmospheric air will enter the fluid motor chamber and unbalance the piston 8 to move the window or closure. when the selector valve is closed, the spring (8! or 33) will seat the atmospheric valve and unseat the companion piston valve. To facilitate this restoration a small bleed orifice 50 may be provided in the piston valve to expedite the pressure equalization on opposite sides thereof outside the seat. The size of the equalizing bleed opening may be practically determined by mounting a smaller wire or plug therein for giving a predetermined clearance.
The window system is an all-fluid one necessitating only one fluid line being brought over to the door from its supporting iamb. No electrical or mechanical remote controls are utilized and therefore the arrangement is simplified. The
.motor operating unit 12 being located adjacent the fluid motor provides for short fluid communications between the latter and the pressure line. This not only facilitates the installation of the fluid motor but also renders the motor quickly responsive to the touch of the motorist. The piston valves actually constitute auxiliary fluid motors for operating the valves of the motor operating unit from the remote selector controls. Each selector valve it may be of any suitable form to admit air through an inlet 52 into the conduit l5 when the valve button 53 is depressed.
The term window" is used herein as inclusive of doors and other closures, the foregoing description being given in detail for clearness and not by way of limitation since the inventive principles involved are applicable to other physical embodiments without departing from the spirit oi the invention or its scope as defined by the appended claims.
