Abstract

A helically driven elevator comprises an elevator body 44 eg a car or carriage, a cylindrical shaft 10 incorporating a helical groove or ridge eg a screw thread, and a stay means 12. The helical shaft is rotated such that the body adapted to move thereon may ride up and down but is prevented from rotation with the shaft by said stay. Alternatively, twin shafts (10 Fig.5) maybe used to move the body. A turn pole 33 means may be provided to assist in manual rotation of the shaft, which may further be miniaturised. In a further embodiment the stay means may be adapted to rotate the body. The elevator may be adapted for movement on a non vertical incline (Fig.4). The elevator aims to provide simple elevation means in a space saving format which may be employed in outdoor, open floor or industrial situations.

Description

Page 1 2335411 St. Augustine Helix (Elevator) This invention relates to a
helix driven elevator.
Elevators are usually powered by hydraulic pistons or pulled using counter-weights. These methods are expensive to manufacture and maintain; passengers are eneJosed in a capsule for protection against dangerous moving parts, which in turn is often built into a well. This makes current designs unsuitable for open floor or outdoor employment.
The object of the invention is to permit simple means of elevation in a space saving format that may be employed in outdoor, open floor or industrial situations.
Helical designs are common in mechanics, used to move boats through water and grain through silos.
According to the present invention a rotating helical shaft moves a liftbody along which is kept from rotating with the shaft by a stay.
A specific embodiment will now be described with reference to the accompanying drawings in which:
Figure 1 shows the lift-body midway up the helix shaft, with manual turnpole and hole for emergency and maintenance.
Figure 2 illustrates a means of traction for the lift-body upon the stay.
Figure 3 illustrates a means of traction for the lift upon the shaft.
Figure 4 illustrates how the system may propel along alternative axes.
Figure 5 illustrates twin turning helix shafts. This system negates the need for a stay.
Figure 6 illustrates how the lift may operate outdoors.
Figure 7 illustrates how the lift may operate on open floors.
Page 2 With reference to the drawings, the elevator comprises a helical threaded shaft 10 and a stay 12, along which the lift-body 44 moves.
The shaft is driven by a geared motor of known design 18 which turns the shaft both clockwise and anti- clockwise. The engine may be situated at either/ both end of the shaft. The passive end of the shaft is secure and able to rotate by ballbearing or other means. The liftbody moves along the shaft via wheels, ballbearings or other low friction means 14 designed within the lift body. The shaft incorporates a helix threaded groove or ridge which the lift body rides, Fig. 3. In order for the lift body to move along, a stay means 15 keeps the lift body from rotating, Fig 2 and allows vertical (horizontal and diagonal if so designed) movement. (Fig 4). Fig. 5 illustrates the exception to this rule employing twin helical shafts allowing movement without a stay.
A manual turning means 33 is a backup for moving the lift for maintenance and emergency.

Claims (1)

  1. Claims
    11 A helix-propelled elevator that is engine powered to turn a cylindrical shaft which incorporates a helical ridge or groove. The lift- body is adapted to ride up and down the shaft with the aid of a stay, which is situated apart from the shaft.
    21 A helix-propelled elevator as claimed in Claim 1 wherein the lift-body traction means is adapted to co-operate with the shaft means in order to assist the movement of the lift-body along the shaft.
    31 A helix-propelled elevator as claimed in Claim 1 or Claim 2 wherein the lift-body means is adapted to co-operate with the stay means in order to assist the movement of the lift-body along the stay.
    41 A helix-propelled elevator as claimed in Claim 2 or Claim 3 wherein the stay means may be adapted to rotate the lift-body means.
    51 A helixpropelled elevator as claimed in Claim 4 wherein twin helix shaft means is adapted to co-operate with the lift-body means.
    61 A helix-propelled elevator as claimed in any preceding claim wherein a turn-pole means may be co-operated with the shaft means to assist manual rotation of the shaft.
    71 A helix- propelled elevator as claimed in claim 6 wherein the means may be miniaturised.
    81 A helix-propelled elevator substantially as described herein with reference to Fig. 1-7.
