DETAELEI) DESCRllTlUN OF 'I HF. PlIliiERRED EMBODEMFNI A supporting structure comprises a pair of laterally spaced triangular support frames l and 2., preferably made from rigid metallic tubing, and each including a horirontal base portion 3, upwardly converging front and rear leg portions 4 and respectively, connected at their lower ends to the front and rear ends of their respective base portion 3, and a side strut 6 extending angularly forwardly and upwardly from the rear end ofits respective base portion 3 and welded or otherwise rigidly secured to its respective front leg portion 4. A rear cross brace member 7 is rigidly secured at its opposite ends to the rear end ofeach base portion 3.
An upwardly and rearwardly sloping treadmill, indicated venerally at 8, comprises a pair of elongated rearwardly and upwardly sloping platelike side members 9 and 10 disposed in 'll parallel rrhltlonfihlft and each disposed ill fill
laterally outwardly of a respective one of the su port lranii s l and 2. The treadmill further includes a lower front transverse shaft 11 extending transversely through the lower front end portions of the side members 9 and I0 and an upper rear transverse shaft l2 journaled in bearings l3 in the upper rear end portions of the side rriernhers Q and 10, a pair of laterally spaced drive sprocket \vliecls I4 keyed or otherwise rigidly mounted on the shut! 52, LL pair of laterally spaced idler sprockets lsjourrialitil on the shaft ll, and an endless flexible conveyor l6 carried by the sprocket wheels 14 and IS. The conveyor 16 comprises a pair of endless link chains I7 each entrained over a different aligned pair of sprocket wheels 14 and I5, and a plurality of steps I8, each step 18 being in the nature of an angular transverse member formed to provide a normally generally horiaontal tread portion 1) and a normally generally vertical riser portion 20. The opposite ends of each trend portion I) are pro ided with pairs of rigid mounting arms 21 pivotally secured ill their outer projected ends 22 to the link chains 17. :is indicated tit 23, see FIG. 7, In like manner. catch riser portion is provided at its opposite ends with a pair of rigid mounting arms 24 having their extended end portions 2.5 pivotal y connected to the link chains 17 at the pivotal connections 23 of run adjacent pair of mounting arms 2|. Each step I8 is reinforced by one or more gussets 26, see FIGS, 4 and 7. The link chains 17, being entrained over the sprocket wheels 14 and 15. define upper operating flights 27 and lower return llights 28, the steps 18 on the return flights 28 being inverted relative to those on the operating flights 27. The treadmill 8 further includes a pair of laterally spaced handrails 29 disposed adjacent opposite ends of the steps I8 and formed to provide legs 30 that are suitably anchored at their lower ends to inturned flanges 3| on the side members 9 and 10. The handrails 29 are further supported by brace members 32 also rigidly secured to the inturned flanges ill, and to the handrails 29. A cushion or padded hood 33 is mounted on the upper rear end of the treadmill 8 by means of mounting brackets or the lilo: 34 bolted or otherwise rigidly secured to end wall portions 35 iifthe hook .33 and to adjacent ones ol'the treadmill side members 9 and Ill.
Means for mounting the treadmill 8 in the frame structure including the support frames 1 and 2, comprises the lower front shaft ll, a cross shaft 36 connected at its opposite ends to the connected upper ends of the leg portions 4 and S of each support frame I and 2, a transverse rockshaft 37 having opposite end portions journaled in the side members 9 and I0 and disposed in spaced parallel relationship to the cross shaft 36, and a pair of laterally spaced rock arms 38 each rigidly secured at its inner end to the rockshaft 37 and having a slot 39 at its outer end through which the cross shaft 36 extends, see particularly FIG. 4. Means for imparting rocking movements to the roclishaft 37, to vary the angular or sloping disposition of the treadmill 3 comprises a lever 40 rigidly secured ill its inner end to the rockshaft 37 adjacent the laterally outer surface of the side member 9 and a toothed quadrant 91 rigidly secured to said outer surface of the side member 9 for engagement with a conventional releasable locking mechanism 42 on the lever 40. With this arrangement, the slope of the treadmill may be varied to suit the operator's needs. It will be noted, with reference to FIG. 3, that the lower front end portions of the side members 9 and 10 are provided with bearings 43 which journal the treadmill 8 at its lower front end on the lower front shaft 11.
For the purpose of imparting a load to the conveyor 16, lliiirl-pressureoperated means is provided, comprising a fluid pump 44, a fluid reservoir 45, and low-pressure inlet and highpressure outlet conduits 46 and 47 respectively connecting the pump 44 to the reservoir 45, the pump and reservoir being rigidly secured to the treadmill side member 9. For the purpose of the present example, the pump 44 is shown in FIG. 8 as being of the rotary vane type, comprising a housing 48 defining a pump chamber 49, a rotor 50 journaled in the hous ing 48 eccentrically within the chamber 49, and a plurality of circumferentially spaced radial vanes 51 radially slidably mounted in the rotor 50. The rotor is mounted on a pump drive shaft 52 disposed in spaced parallel relationship to the upper rear treadmill shaft 12, and is connected thereto by sprocket wheels 53 and 54 mounted on the shafts 52 and I2 respectively, and an endless link chain 55 entrained over the sprocket wheels 53 and 54. Preferably, a relatively heavy flywheel S6 is mounted on the pump drive shaft 52 to aid in smooth running of the apparatus.
The reservoir 45 is formed to provide a valve body portion 57 having a fluid passageway 58 therein that extends from the outlet conduit 47 to the interior of the reservoir 45. The passageway 58 is normally closed by a valve element 59 slidably mounted in an opening 60 in the valve body 57 and yieldingly urged toward a valve-closed position by a coil compression spring 61 interposed between the valve element 59 and the collar 62 of an adjustment screw 63 that is screw threaded through a retaining or packing nut 64 screw rhreadedly received in the valve body portion 57, see FIGv 8. The passageway 58 is provided with a tapered portion 65 through which fluid flows from the conduit 47 to the interior of the reservoir 45 at a gradually increasing volume as the valve element 59 is moved against bias of the spring (rl away from its valve-closed position shown in FIG. 8.
The inturned flange 31 of the side member 9 overlies the pump 44, reservoir 45 and valve body portion 57, and pro vides an instrument panel on which is mounted a springwourid clock or timer, the dial of which is indicated at 66. see particularly FIG. 5. A fluid pressure indicator 67 is interposed in the conduit 47, and includes an indicator dial 68 disposed adjacent the timer dial 66. The adjustment screw 63 projects upwardly and outwardly through an opening in the panelforming flange 31 and is provided with a control knob 69, Also mounted on the panel-forming portion of the flange 3| as sociated with the side member 9 is a conventional counter mechanism 70 having an actuator 71 that is adapted to be engaged by suitable means, such as the steps 18, to indicate the number of steps traversed by a person using the exerciser In use, as the operator mounts the steps [8 associated with the operative flight 27, the weight of the user will cause the conveyor 16 to move, imparting rotation to the shaft 12 and consequent operation of the fluid pump 44 in a direction to force fluid through the conduit 47 toward the reservoir 45. Pressure of fluid in the conduit 47 will be indicated on the dial 68, and will tend to move the valve element 59 toward an open position against bias of the coil spring 61. Should the operator's weight be insufficient to impart downward movement to the operating flights 27 at a speed equivalent to the operator's walking pace, the control knob 69 is rotated in a direction to decrease bias of the spring 61 against the valve element 59, whereby the valve element 59 will be opened further under pressure ofthe fluid in the conduit 47 to permit faster rotation of the pump rotor 50 and consequent forward and downward movement of the operating flights 27. On the other hand,
should the uscrs weight cause the operating flights 27 to move forwardly and downwardly at a speed greater than the operators desired walking speed, the control knob 69 is turned to effect greater bias of the spring 61 against the valve element 59, to increase the load on the pump 44.1 hus, the exerciser is capable of use by persons of various weights and walking speeds By manipulation of the lever 40, the slope or pitch of the treadmill 8 may be varied to a limited degree, to provide for different climbing angles. Operation of the exerciser is completely dependent on the weight and effort of the user, and requires no outside source of power except that used by the timer 66.
