BACKGROUND OF THE INVENTION This invention relates to new and useful improvements in treadmills.
The exercise of running, commonly known as jogging, has been established as beneficial to the health and is being widely accepted. Many persons desiring to exercise in this manner `are not able to do so in view of the lack of facilities such as a place to run. The art of such exercise can be developed under a specic program, namely the traveling of a certain distance in a certain time. Such a program to be successful must be closely supervised in order to advance the training as determined by the distance to be run as well as the rate of running. Treadmills have heretofore been provided but a planned program of running is not conveniently possible in their use because the distance and rate of travel can not be accurately established in a planned program of running.
SUMMARY OF THE INVENTION Accordingly, applicants invention is directed to a treadmill having as its primary objective to employ distance measuring means in combination therewith. Other objects are to provide a treadmill of the type described having a -belt driven 'by an electric motor and also having distance measuring means operating a switch in the circuit of the motor arranged to shut off the motor after a selected distance is traveled by the belt; to provide variable speed control means also in the circuit of the motor for varying the speed of the belt; and to provide timing means in the circuit of the motor to keep track of belt operating time.
Another object is to provide a treadmill having a hand rail and means on the hand rail for supporting an instrument housing in a conveniently viewable and accessible position.
Another object is to provide a treadmill with a traveling belt having a conditioning surface for the feet of runners exercising thereon.
Yet another object is to provide a treadmill of the type described having a jointed frame and belt arranged such that said frame and belt can be compacted for shipment and storage.
The invention will be better understood `and additional objects and advantages will beome apparent from the following description illustrating a preferred form of the device.

FIG. l0 is a wiring diagram of electrical operating means for the treadmill.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now in particular to the drawings and rst to FIGS. l-6, the treadmill of the invention comprises a frame including a bottom plate 10, a belt Support plate 12 and upright reinforcing struts 14 connecting the bottom plate 10 and belt support plate 12 into a rigid frame. Supported at each corner of the bottom plate 10 are short posts 16. A pair of the posts 16 at one end of the frame support for free rotation end shafts 18 of a drurn 20. A
pair of the posts 16 at the other end of the frame rotatably support end shafts 22 of a drum 24. One of the end shafts 22 extends through its respective post 16', as seen in detail in FIG. 5, and has a drive connection 26 with a variable speed electric motor 28 secured to a side extension 30 of the bottom plate 10. Motor 28 operates the shaft 22 through a gear reduction mechanism 32.
Operative over the drums 20 and 24 and driven by the latter drum is an endless belt 34 traveling over the top surface of plate 12, the said plate supporting the belt in a flat plane to provide a good running surface. Preferably, the belt 34 is provided with a plurality of apertures 36 which serve in one instance to provide traction on the belt and in a second instance to massage and condition the feet. Although the conditioning means for the belt are illustrated as apertures, it is to be understood that other means, such as small cleats or knobs can be used to accomplish the gentle massage desired while the person is walking or running on the treadmill. Also, the drive connection 26 preferably comprises an overrunning clutch type connection or the like so that the belt will not come to a sudden halt when the motor stops. Thus, the runner will not lose his balance when the motor stops.
A pair of the end posts 16, preferably at the idler drum end, have adjustable support longitudinally of the frame 10 so that a desired drive tension can be applied to the belt 34, and for this purpose the posts have flanges 37 which receive bolts 38 passing through elongated adjustment slots 40 in the frame 10.
1 and 2. By means of the handrails 46 a person can steady himself while getting on or ot the treadmill and while in the act of walking or running on the treadmill.
Means are provided for indicating the distance traveled by the belt 34, and for this purpose a conventional odometer cable 48, FIGS. l and 2, leads from the gear reduction mechanism 32 to an odometer 50 supported in a housing 52 secured to the handrail 46. The mechanical connection of the odometer cable between the gear reduction mechanism 32 and the instrument 50 is accomplished by conventional and well understood means. The odometer 50 has a distance indicating needle 50a and mileage designations 50b as desired, such designations preferably comprising to 2 miles in fractions of one-fourth miles.
Also supported in the housing S2 are variable speed control means 54 for the motor 28, whereby the motor can be operated at selected r.p.rn.s to achieve a desired miles per hour linear travel of the belt. The variable speed control means 54 may have a selected number of settings S8, comprising slow, medium and fast or additional settings including an off setting.
The housing 52 also supports a timer 60 of conventional construction. Preferably the timer has minute and second hands and suitable minute and second designations clearly imprinted thereon for ready viewing by the runner.
In a preferred construction, and with particular reference to FIG. 10, odometer 50 operates a switch 50c in circuit wires 56 of the motor 28. Switch 50c is arranged such that when the needle 50a is at the zero mileage position the switch is open but at all other positions of the needle the switch is closed. Thus, the switch is in closed circuit position in all settings except its zero setting. Preferably, the needle 50a is driven in one direction only, namely, in the counterclockwise direction as viewed in FIG. 2, and may be hand set in a clockwise direction whereby the runner can set the odometer needle to a desired distance and the odometer needle will then be returned to zero under driving power of the cable 48. Such odometer structure is of conventional structure and therefore is not detailed herein.
As thus apparent, the motor is capable of operation while the odometer needle is set on any mileage designation except zero and will be shut off when said needle reaches zero. The variable speed control 54 is also arranged to control the operation of the motor in that it operates a switch 57, FIG. 10, in the circuit to the motor. More particularly the switch 57 is arranged to `be open in the olf position of the speed control 54 but to be closed in all other positions. Thus, in order for the motor to be put in operation, switch 57 must be on any position other than its olf position and the needle 50a must at the same time be in any position other than its Zero position.
In the operation of the treadmill a person can set the pace desired by suitable adjustment of the variable speed control means 54. Such speed control means can cause operation of the belt at a walking speed or at a maximum running speed such as a speed amounting to a fourminute mile if desired. By proper setting of such control means a person can run at the desired miles per hour in following a conditioning program. That is, he may wish to run at a slow speed in initiating the training program and as his condition improves he may run at a faster pace. Such is accomplished by proper settings of the control means 54. The distance to be walked or run is set by selected adjustment of the odometer needle 50a. Thus, certain distances can be walked or run at a selected pace. When a person desires to exercise, he rst steps onto the treadmill and then sets the odometer needle to the distance desired. Although the switch 50c closes when such setting is made, the circuit to the motor is still closed, assuming of course that the speed control means 54 is set on its off position. The person can then move the speed control means 54 to its rst position to close the circuit to the motor and place the treadmill in operation.
This first position may comprise a walking speed of the belt, so that the person can initiate his movements with balance. The speed control means can then be moved up to a faster setting gradually so that the runner can still maintain his balance. Such gradual build-up of speed is not mandatory, however, since the handrails can be used for maintaining balance even when starting out at a fast pace.
It is desired that the treadmill be knocked down for shipment and storage, and for this purpose the bottom frame plate 10 and belt support plate 12 have transverse jointed connections 62 at approximately their centers, FIGS. 1 and 3. Such connections comprise a hinge connection which may be readily separated by removal of a hinge pin 64. Belt 34 has a similar jointed connection 66, FIGS. 2 and 7, disconnectable by a cross pin 68. Also the handrails 46 are formed in two parts with one of the parts having a projection removably tted into a hollow end 72 of the other part as shown in FIG. l. Each of the railing parts has a hinged connection 74 with their respective standards 44 for folding and each of the standards 44 is removable from the sockets 42 in the posts 116. Thus, for shipment or storage the standards for the side rails can be removed from the sockets 42 and then the two portions of the side rails separated and folded to a condition shown in FIG. 9. Thereupon, the belt may be removed from the drums by removing the pin 68 and the frame knocked down in two parts by disconnection of joints 62. The frame may be stored or shipped in the condition shown in FIG. 8. For the purpose of partial dissasembly as just described, odometer cable 48 and the electrical lines have suitable conventional plug-in connections, not shown.
It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.
Having thus described my invention, I claim:
1. A treadmill comprising:
(a) a frame,
(b) a pair of parallel drums on said frame disposed in spaced relation,
(c) an endless belt operating over said drums,
(d) power means for driving one of said drums to cause linear movement of said belt such that a person can run on the belt to keep up with the travel thereof,
