Definitions

  • the present invention relates to a device for moving people or items on the Jewish Sabbath and certain Jewish holidays in a manner that is widely acceptable within Jewish Law through powering this invention with municipal water or steam.
  • This invention in its simplest form accomplishes Sabbath acceptance by extending a single acting hydraulic cylinder or turning a hydraulic motor by way of a connection to the municipal water or steam system to power the lift of a platform or turning a winch or conveyor.
  • municipal water includes steam and each mechanical alternative is for the purpose of Sabbath acceptance.
  • the water enters the hydraulic cylinder by way of a valve (or another set up that accomplishes controlling or directing the flow) that allows the municipal water to enter the hydraulic cylinder below the piston to raise the load and subsequently, exit the hydraulic cylinder (lowering the load due to the load's weight) by shutting off the flow of the municipal water and dumping the water within the hydraulic cylinder to the sewer, a storage system or other place.
  • the water would enter the motor through a valve (or other) to turn a winch, sprocket, vacuum pump, air pump, or other method/device of power transmission to lift the load.
  • the load would be lowered by stopping the flow or reversing the flow through the hydraulic motor and subsequently, through a brake system, a clutch system, or other method of transmission if and as needed.
  • the operation of the transportation device powered by municipal water and its contained energy (pressure) can have complex hydraulic systems controlling many functions required for their safe and controlled operation.
  • These transportation devices can additionally supplement movement by way of stored energy in a counterweight, flywheel, accumulator, spring, or any other current technology to accomplish moving the load. Gravity can also be used to move the load.
  • This invention with its broad array of applications, is designed to overcome Sabbath restrictions on the use of an elevator (or platform lift, etc.).
  • Basic operation of raising and lowering the platform is relatively simple.
  • Some methods of shifting from Sabbath and weekday modes can be as follow: by manually shifting certain auxiliary valves and flipping one or more electrical switches by using a parallel control (FIG 4) within the elevator platform and at each landing which on weekdays activates the pump as needed, electrical components as needed, and any other non- Sabbath features as needed, by interfacing with available data that shifts the modes at the proper times, by timers, or by some other method.
  • FOG 4 parallel control
  • This invention will allow far greater mobility on the Sabbath for those in need and those who refuse to use electric Shabbat elevators because of the Rabbinic opinions that electric elevators are forbidden on the Sabbath.
  • An additional benefit of this water operated elevator is that it can be operated on demand, whereas for those that allow the electric Sabbath elevators, the elevators wear and waste energy by operating continual ly at whatever interval is set.
  • a Shabbat elevator encompasses a platform, fra mework, track, hydraulic cylinder, and control valve connected to the municipal water system. (FIG 3)
  • the valve When the platform is in the down position, the valve has dumped the water from the hydraulic cylinder (either to a sewer line, storage tank, a pond, or elsewhere) while blocking the flow of municipal water into the hydraulic cylinder.
  • the valve When the platform is to rise, the valve is positioned to allow the municipal water at its delivery pressure to enter the hydraulic cylinder below the piston, which results in the cylinder rod extending and raising the attached platform until the full stroke has been achieved.
  • the valve prevents the water from flowing out of the hydraulic cylinder by either maintaining the pressurized m unicipal water flowing into the hydraulic cylinder or by shutting off the flow and preventing flow out of the cylinder.
  • the valve is positioned to allow the water in the hydraulic cylinder to dump (either to a sewer line, storage tank, a pond, or elsewhere).
  • Applications for this simple design might include free standing handicapped lifts, basic dumbwaiters, dock lifts or low-cost elevator applications where there are no code restrictions.
  • Standard form two levels, single acting hydraulics, door safeties, and cushioning
  • door safeties allows an added degree of safety for the operation of the elevator.
  • Each level will have a locked door when the elevator cab is not positioned at the door. The door will be released either hydraulically or mechanically by contacting the cab directly or through linkage. The elevator will not be allowed to move if one of these doors is open.
  • a gate in the cab can isolate the moving elevator passengers from contacting the stationary walls and doors outside of the cab. This gate can be linked to the safety system in such a fashion that the cab will not move until the gate is closed if operated from within the cab. Hydraulically, these safeties will either directly cut flow off from or to the hydraulic cylinder or cut flow from or to the cab's control valve directly or through a hydraulic control circuit. All other hydraulic circuitry will be similar to 'simplest form' described above.
  • the addition of controls at each level will add considerably to the functionality of the elevator.
  • the elevator will be able to be recalled to the other floor remotely from a control valve at each level. Hydraulically, this will complicate the circuitry even more.
  • the circuitry will isolate the operation of the activated control valve from the operation of the other two control valves. This means that operating the cab's control valve will make the fixed control valves at each level inoperable. Operating one of the fixed control valves to retrieve the cab will make the cab's and the other floor's control valves inoperable.
  • the safety circuitry for the gate inside the cab which prevents the operation of the elevator from the cab when not in the closed position should not prevent the retrieval of the cab from the other levels if the gate is not closed.
  • Cushioning will be accomplished either by cushioning valves, by a cushioned hydraulic
  • a double acting hydraulic cylinder(s) may be necessary when all cushioning is to be accomplished by the cylinder(s) itself.
  • Multilevel form three or more levels, single or double acting hydraulics, door safeties, controls at each level to retrieve the elevator, and cushioning.
  • Precise cylinder stroke The cylinder can be manufactured to a specific length, with or without internal cushioning to accurately move between two levels. If additional levels are required, additional cylinders of precise stroke can be stacked (with or without a framework) in such a way that each cylinder can
  • these multiple cylinders could be of specific length and placed side-by-side to operate a cable reeving system that would accurately move the cab to the desired position.
  • the cab will have a horizontally sliding actuator (FIG 5) positioned to mechanically contact the staggered valve at each level to stop the load at that predetermined level.
  • the elevator lift power will come from
  • the elevator can operate from a reservoir and pump, or by an electric winch, with electrical controls, or by any other variation and features found in other elevators.
  • the Sabbath function will turn off or simply not activate all of these prohibited features (prior to the Sabbath beginning), while activating those functions necessary for Sabbath operation. This shifting to and from the Sabbath function can be accomplished in various ways which can include points below or a combination thereof as follow:
  • Automatic switching between Sabbath and weekday mode can be accomplished by a dedicated or remote computer monitoring the exact times and dates that the Sabbath function needs to operate in conjunction with electrically operated weekday valves and manual Sabbath day valves (possibly, appropriate valves are available that can operate both electrically and manually). Automatic activation of the necessary switching when necessary will remove concerns that manual switching might be forgotten until the switching would be prohibited on the Sabbath, making the elevator unusable on the Sabbath.
  • Automatic switching between Sabbath and weekday mode can be accomplished by preset timers.
  • the Sabbath function could be added to an existing elevator installation.
  • This invention will allow far greater mobility on the Sabbath for those in need and those who refuse to use electric Sabbath elevators because of the Rabbinic opinions that the electric elevators are forbidden on the Sabbath.
  • An additional benefit of this water operated elevator is that it can be operated on demand, whereas for those who allow the use of electric Sabbath elevators, the elevators wear and waste energy by operating continually at whatever interval is set.
  • FIGURE 1 STAIRLIFT
  • This drawing shows an application of this invention using municipal water 6 to power a diagonal lift/movement of a seat 2 on its track 1 using a water powered hydraulic motor 5 (as opposed to the hydraulic cylinder) for accomplishing movement up the stairs 4.
  • the pictured simple hydraulic circuit depicts a valve 3, municipal water line 6, and the dump to sewer line 7.
  • FIGURE 2 CONVEYOR/ESCALATOR
  • This drawing shows more applications of this invention using municipal water to power conveyor/escalator using a water powered hydraulic motor 2 turning sprocket/pulley 1 and in turn, turning the conveyor/escalator.
  • the pictured hydraulic circuit depicts the valve 3, municipal water line 4, and the dump to sewer line 5.
  • FIGURE 3 - ELEVATOR WITH HYDRAULIC CURCUIT
  • This drawing shows a basic layout of a two-story elevator using a hydraulic cylinder 15 powered by municipal water 1.
  • the pictured hydraulic circuit depicts the incoming municipal water line 1 and the exiting dump to sewer lines 17 and the two landing doors 2 and 14.
  • Three manual control directional) valves are pictured - control 7 inside the cab 8, second floor cab retrieval valve 5, and first floor cab retrieval valve 16.
  • Three manually actuated safety valves are pictured -- two valves 4 with their actuator arms 3, which sense an open landing door(and in turn shut off water to and from the hydraulic cylinder) and a shut of valve 9 and its actuator arm 6, which senses the internal cab door (not pictured) being open (and in turn shuts off water to the cab control valve 7.
  • Hydraulically activated valve 13 shuts off flow to and from the hydraulic cylinder 15 when landing doors are open. Hydraulically activated valves 10 throughout this hydraulic circuit are used to selectively isolate various lines as necessary and use dashed lines to each spring-loaded valve's hydraulic cylinder for activation and dumping. Specific valves have yet to be determined, and as such the exact line layout can not yet be depicted. This layout approximates the necessary components, but not necessarily an exact hydraulic circuit.
  • FIGURE 4 DUAL OPERATING CONTROLS
  • This drawing shows a cabinet with parallel controls in the elevator cab and at each landing - one control for Sabbath and one control for weekdays. Sliding door 4 from left to right or visa-versa by use of a knob (or other similar item) 2 determines which control is accessible and which mode the elevator is in. The text on the control units will be visible on the control units to guide the users. Attached to the control valve (not visible) 5 is the handle/knob 3 that instructs the cab to move up or down.
  • FIGURE 5 ACTUATOR TO CUSHION AND STOP CAB AT DESIRED LANDING
  • This drawing shows one alternative for selecting desired landing by sliding a knob and attached actuator (shaft with rounded end in this drawing) which places that actuator directly in line to contact a landing valve located near the desired landing.
  • the stationary landing valves are staggered at each floor in order to align with the position of the actuator at each control positioning (selection).
  • flow to the elevator begins to be restricted, causing the elevator to slow and finally stop when the valve is completely closed.
  • Floor (landing) selector body 1 contains a sliding member 3 with actuator shaft 4 penetrating it, extending to the front (left) for the attachment of a hand knob 2, and to the rear (right) a rounded end which will contact a t-lever 6 to cushion and stop the elevator travel at the selected floor.
  • Actuator can contact and shift valve from the top or bottom of the t-lever depending on direction of travel.
  • This drawing shows one example of using linkage as opposed to hydraulics for some of the functions.
  • the top drawing looks down upon the linkage from the elevator cab to the directional valve 4 at the bottom of the elevator.
  • the elevator passenger shifts knob 3 which pivots the upper linkage 1, which in turn rotates square rod (or splined or other) 6 and its lower linkage arm 2 to shift valve 4, causing the water to either enter or exit the lift cylinder causing the elevator to either rise or descend.
  • Bearing 5 hold the square rod in position, while upper linkage 2 (attached to the elevator cab) slides up down on square rod 6.
