The treadmill-type unit 120 includes a main generally rectan-gular frame including longitudinal side walls 121, 122, front transverse wall 123 and rear transverse wall 124. Side walls 121, 122 support a front roller 125 and a rear roller 126 journalled therein in the usual manner by means of bearings (not shown). Also rotatably supported between side walls are a plurality of support rollers 127. These support ro]lers preferably are lengths of hollow synthetic plastic pipe having apertured plugs 128 at each end, through which a shaft 129 extends, either as a continuous shaft or as two stub shafts.
The front roller 125 is provided with flywheel weights 130 to provide both drag in starting and momentum while moving a treadmill end-less belt 131 entraining rollers 125, 126. The belt is preferably formed of reinforced rubber. Adjustment of roller 126 is provided by bolt 132.
2~:39 A pair of upright arms 133 project upwardly at front wall 123, and the upright arms are interconnected by a transverse handle 134.
Rubber pads 135 provide Eloor support.
Figure 3 shows in greater detail the adjustable roller 126 mounted to the roller supports. Figure 3A shows, more clearly, the adjust-ment of the roller 126 by means of the two adjusting bolts 132.
Cycle-type unit 20 is connected to treadmill-type unit 120 by bolts 11 between fralQe 22-and wall 123. A drive chain 136 is connected between sprocket 27 and sprocket 137. ~hile a sprocket/chain drive is shown, a drive pulley/belt drive may also be used. ~hile restraining drag is shown to be provided by flywheel weights 130, it is also possible to use controllable brake drag means (not shown) on the chain drive/belt drive.
Figure 7 shows a variant of a treadmill-belt support in the form of a support plate 138, whose upper surface 139 is partly or com-pletely covered with a polytetrafluoroethylene low friction surface.
Figure 8 shows one variant of a treadmill-unit frame box. It includes side walls 121, 122, front wall 123 and rear wall 124 formed of sheet metal having their bottom edges 150 folded under to provide perimeter bases 151. A plurality of spaced-apart side L-shaped brackets 152 secured to the inside of walls 121, 122 support inner side walls 153, 154, whose upper edges 155 are folded to provide side ledges 156. and are secured thereto through bolt holes 159. Apertures 158 in side wall 153, 154 support the shafts of rockers 127.
Figures 9 and 10 show a partial view (i.e., the frame bnly) of another variant of this invention, with the pedal crank mechanism and the - treadmill operating mechanism not shown for clarity. The cycle-type unit 20 is connected to the treadmill-type unit 120 by a cross-bar 175 and a hinge connection 176. As seen in Figure 9, the two units are on the same hori~ontal plane, for light eY.ercise. In Figure 10, leg 179 of adjustable height is disposed between units 120 and 20 to provide for more vigourous exercise.
In summary, roller supports are attached to a rectangular box-type frame, preferably by means of bolts. Id]er rollers are rotatably mounted to roller supports by means of shafts. The rollers are preferably constructed from pla~tic tubing, e.g., formed of polyvinyl chloride or polypropylene, ~ith wood dowels in each end and an OILITE (registered Trade Mark) bron~e bushing pressed into the ~ood dowels. Shafts are secured to the roller supports preferably by means of bolts threaded into the ends of the shafts. The rear roller is a longitudinally adjustable roller for adjusting the tension on the treadmill belt. Tt~o forward drive rollers are keyed to a common shaft by means of flywheels. The flywheels help provide momentum for self-propelled jogging. The common shaft is rotatably mounted to the roller supports preferably by means of OILITE
(registered Trade Mark) bushings pressed in the roller supports.
The tubular frame is attached to the reactangular box-type frame preferably by means of bolts for easy disassemblying. A seat is attached to the cycle frame and its height is adjustable by mealls of an adjusting bolt. Pedals are attached to the frame by means of a tubular support and a support plate. The pedals operate a drive sprocket ~hich is coupled to a driven sprocket, by means of a drive chain.
The support plate has elongated holes allowing the drive sprocket to be moved ahead and back for adjusting the tension on the drive chain. Handlebars are attached to the cycle frame to support the person pedalling and handlebars are attached to ~he treadmill frame to support the person jogging.
The rectangular box-type frame is attached to the tubular cycle frame preferably by bolts. In use, the top underside of the treadmill belt rides on the idler rollers. The adjustable roller applies the p proper tension on the belt and the drive rollers drive the belt. The drive rollers are driven by means of pedals which operate the drive sprocket which drives the chain and the driven sprocket on the treadmill unit. A chain guard protects the chain.
In one embodiment of the rectangular box-type frame, the front and back ends have folded edges over both the top and the bottom, and the sides are folded on the bottom only. This is for added strength and to provide an aesthetically pleasing finished look. The roller supports have the top edges folded for the same reasons. The roller supports are pre-ferably bolted to the box-type frame by the L-shaped brackets welded to the sides of the box-type frame.
In another embodiment, the rectangular box-type frame has a level top and may be arranged to have a level base. It would be used in this position when used by a person pedalling and a person jogging or a person pedal]ing only. The box-type frame may be on an incline and may be supported by legs while the tubular frame is tilted back and still attached to the box-type frame. This is done by means of a hinge connec-tion.
The incline on the box-type frame is desirable when a person is jogging alone and self-propelling the treadmill belt. Although it is possible when the belt is propelled by a person pedalling and a person jogging, the belt could overspeed and cause problems for the pedaller.
With the adiustable incline on the box-type frame when being used by two people, the belt can be parallel to the floor and cannot be self-propelled, and when used by a jogger only can be set to an incline and self-propelled, having the same advantages as the fixed machine.
an endless drive chain entraining a pair of spaced-apart drive sprockets.
By still another variant, the endless drive member (10) com-prises an endless drive belt entraining a pair of spaced-apart drive pulleys.
By a further variant, the drag means (11) comprises a variable brake associated with the pedal drive.
By a still further variant, the drag means (11) comprises fly-wheel weights associated with the treadmill drive.

The tubular frame is attached to the reactangular box-type frame preferably by means of bolts for easy disassemblying. A seat is attached to the cycle frame and its height is adjustable by mealls of an adjusting bolt. Pedals are attached to the frame by means of a tubular support and a support plate. The pedals operate a drive sprocket ~hich is coupled to a driven sprocket, by means of a drive chain.
The support plate has elongated holes allowing the drive sprocket to be moved ahead and back for adjusting the tension on the drive chain. Handlebars are attached to the cycle frame to support the person pedalling and handlebars are attached to ~he treadmill frame to support the person jogging.
The rectangular box-type frame is attached to the tubular cycle frame preferably by bolts. In use, the top underside of the treadmill belt rides on the idler rollers. The adjustable roller applies the p proper tension on the belt and the drive rollers drive the belt. The drive rollers are driven by means of pedals which operate the drive sprocket which drives the chain and the driven sprocket on the treadmill unit. A chain guard protects the chain.
In one embodiment of the rectangular box-type frame, the front and back ends have folded edges over both the top and the bottom, and the sides are folded on the bottom only. This is for added strength and to provide an aesthetically pleasing finished look. The roller supports have the top edges folded for the same reasons. The roller supports are pre-ferably bolted to the box-type frame by the L-shaped brackets welded to the sides of the box-type frame.
In another embodiment, the rectangular box-type frame has a level top and may be arranged to have a level base. It would be used in this position when used by a person pedalling and a person jogging or a person pedal]ing only. The box-type frame may be on an incline and may be supported by legs while the tubular frame is tilted back and still attached to the box-type frame. This is done by means of a hinge connec-tion.
The incline on the box-type frame is desirable when a person is jogging alone and self-propelling the treadmill belt. Although it is possible when the belt is propelled by a person pedalling and a person jogging, the belt could overspeed and cause problems for the pedaller.
With the adiustable incline on the box-type frame when being used by two people, the belt can be parallel to the floor and cannot be self-propelled, and when used by a jogger only can be set to an incline and self-propelled, having the same advantages as the fixed machine.
