Definitions

  • This machine relates to exercise machines of the kind comprising a moving staircase.
  • a moving staircase In such machines, there is a series of steps, and the person taking the exercise perpetually ascends the staircase, using energy to displace the stairs downwardly or simply using energy to lift the use of legs with the user's weight displacing the stairs, so that the user actually marks time and stays in the same place.
  • the movement may be braked to provide resistance or the staircase may be governed to run at a particular speed.
  • One known moving staircase exerciser in U.S. P 3 497 215 has a pair of endless chains e.g. roller chains with the steps lying between those chains.
  • the steps are pivoted to shafts carrying rollers at each end and the rollers run in an endless loop track.
  • the chains follow a different course from the track at the ends of the loop, that is the points where the individual stairs invert to run through a return portion of the loop. This allows the chains to extend linearly between each two shafts even at the ends of the loop.
  • the chains and track form an expensive and complex part of the complete exerciser.
  • the object of the present invention is to provide an exerciser of this kind which will be more economical to manufacture and hence less expensive.
  • a moving staircase exerciser comprises a plurality of steps, each step having a riser and a tread fixedly connected together, and each step being pivoted to the next step so as to make an endless loop of steps, a pair of straight guides at each side of the staircase, a wheel or roller on each end of each pivot axis between each two adjacent steps, the wheels or rollers running in or on said guides, and a geneva wheel mechanism for carrying the wheels or rollers from one guide to the other of the same pair at least at one end of the guides.
  • geneva wheel is meant a rotating structure having a plurality of recesses about its periphery and spaced apart at suitable distances so that when one pivot is engaged in one recess and the structure rotates, the next recess moves into position to pick up the next pivot and so on.
  • the number of recesses and hence the number of pivots engaged with the geneva wheel at any time will depend upon the design but in general the minimum number will be three.
  • the geneva mechanism may be provided at one end of the loop only.
  • the guides may consist of a pair of e.g. parallel straight portions for example of angle or channel section in or on which the wheels or rollers run, but preferably the guides form U-shaped structures so that the parallel portions are connected by an arcuate portion at one end, and the geneva mechanism is provided at the other end.
  • the machine comprises a skeleton frame with an appropriate casing (not shown) supporting two U-shaped track assemblies each of which is made from a length of channel section material, with the U's lying in parallel planes and with the mouths of the channels facing one another.
  • Each track assembly has two parallel portions 10, 12 and a curved portion 14 connecting adjacent ends.
  • the curve 14 is at the bottom of the upwardly inclined track portions, and at the top is located shaft 16 carrying geneva wheels 18.
  • the shaft is driven by motor 20 via appropriate gear connections and with suitable control circuitry and the like.
  • the geneva mechanism has three equi-spaced recesses 24.
  • the steps comprise a series of generally L-shaped components of which one limb 26 forms a tread and an adjacent integral part 28 forms a riser.
  • the top of each riser is formed with a knuckle joint or pivotal connection at 30 connecting it to the next adjacent tread.
  • Each hinge pin connecting two steps extends transversely of the steps at each end to carry a roller 32 at each end and the rollers are arranged to run in the channel section tracks.
  • rollers 32a, 32b are engaged in two of the recesses and the third geneva recess is disengaged. At other points in the location of the geneva wheels 18 only a single shaft is so engaged and two of the recesses 24 are empty.
  • the step construction may comprise a light alloy extrusion of constant cross-sectional shape cut in suitable lengths, one length to each step, and providing an area 36 at the outer edge of each tread and also carrying the pivot joint with the adjacent riser, together with an L section length of metal plate or sheet metal bent to provide the major portion of the tread 26 and the riser 28, and a pair of side plates 38 which are apertured in two places for a pair of the pivot shafts 30 to extend therethrough, one at the top and one at the bottom of each step and each of those shafts connecting the adjacent steps.
  • the side plates may be for example brazed or welded to the sheet metal or metal plate and to the extrusion so that each step is a relatively rigid unitary whole.
  • the complete apparatus may be associated with hand rails which the user may grasp to maintain balance, and any required control panel can be mounted on the hand rails.
