This invention relates generally to the class of exercising devices, and has more particular reference to an apparatus'by vir- I tue of which all the advantages of walking 5 are gained, while some of the disadvantages thereof, under present conditions, are eliminated. I

It is a well recognized fact that walking under proper conditions is oneof the most healthful and beneficial exercises known to mankind, but under the conditions ,in which we now live, especially-those of us who are located in large centers of: opulation, walkin g cannot be classed in t e category of a healthful and beneficial exercise, Some of the principal reasons for this are: First, the lack of a proper surface upon which to walk without subjecting the nervous system to a 0 jarring and tiring effect, a

by dust, dirt, smoke, noxious fumes from motor vehicles and other impure and objectionable matter with which theusual city air is laden.- V

It; is, therefore, the main object of the present invention to provide an improve apparatus or device, by the use of which there may be obtained as complete a walking exercise as is possible, including the proper knee bend, a correct walking posture with a slight forward inclination of the body and the weight shifted onto the ball of the foot, and this without subjecting the system to the jars, shock, strain and fatigue which accompany actual walking 'on hard city pavements, streets or roadways.

The'invention more particularly resides in an apparatus of the indicated character which includes a mobile platform for each foot, mounted for guided and practically unhampered limited movement in defined paths parallel to each other and in the sameinclined plane, and in which said platforms are connected so as to permit of their manual reciprocation simultaneously but in op-' posite directions.

The invention further comprehends an apparatus as previously set forth, which is adjustableto increase or decrease theinclination of the plane of thepath of movement 'rections while using and, second, the lack of an atmosphere free of contamination cause the carriages of the platforms, so that in so doing, the user may gain the effect of either ascending or descending an inclination or hill which is of varying degrees by'facingin opposite di the device. 7 The invention still further embodies, in such an apparatus, an inclined su port for foot platforms, in which said plat orrns are independently adjustable from a positionrto afford a foot supporting surface coincident with the plane of the support to a position affording a horizontal surface, and further to afford a supporting surface variously in: c lined opposite to the inclination of the support for the foot platforms. i

Other objects of. the invention reside, in the simple and novel features of construm tion of the a paratus, the economy with which it may be produced and maintained in operating condition andthe general efiiciencyv derived therefrom. r. With the above recited and other objects in view, reference is had to the following description and accompanying drawings, in which there is exhibited one example or embodiment of the invention, while the claims define the actual scope of the same.

In the drawings: a Figure 1 is a longitudinal sectional view through an exercising ap aratus constructed in accordance with the invention, said section being taken on a vertical longitudinal plane indicated by the line 1-1 of Figure 2. Figure 2 is a plan view of the apparatus. Figure 3 is an enlarged transverse sectional View therethrough, taken approximately on the line indicated at 3 -3 in Figure 1. Figure 4 is a diagrammatic view illustrating the form of connection employed to to simultaneously move in opposite directions.

Referring to the drawings by characters of reference, A designates a supportingbase, which may be of any suitable material, and which in the present instance is illustrated as including a wooden plank'or panel 5 of substantially oblong configuration, provided at one end with a transversely'disposed depending cleat or cross element 6, which when supported on, a horizontal surface disposes the base and its upper surface 7 at an inclination to the horizontal. The upper surface 7 is subdivided transversely to define a pair of laterally spaced parallel guideways or channels 8 and 9 by means of a medial longitudinally extending upstanding strip 10 and by marginal longitudinally cxtend ing upstanding strips 11 and 12, the said structure defining the guideways or channels 8 and 9, each of which is formed by portions of the uppersurface 7 and by the confronting side faces 13 and, 14 of the intermediate and marginal strips 10, 11 and 12. The guideways he obviously formed in other equivalent ways, such as by employing a thick panel 5 which is provided with parallel longitudinal grooves, or if constructed from metal, by bending, stamping, pressing or otherwise. The base is also provided at-the lower end, namely, that end opposite to the one provided with the depending cleat 6, with a transversely disposed upstanding element or cleat 15 which is secured to and projects upwardly from the upper surfaces of the strips 10, 11 and 12.

In order to provide means for increasing the inclination of the base 5 so as to support the upper surface 7 at various inclinations, a pair of jackscrews 16 arethreaded vertically through the transverse depending element or cleat 6 and extend loosely through openings 17 in the base panel 5. The upper ends of the jackscrews 16 are formed with manipulating heads or handles 18 for rot-at ing the jackscrews to effect the adjustment of the inclination of the base. i

The apparatus further includes a pair of foot supporting carriages, designated 1 gene rally by the reference characters B and (l, of identical construction, each of which consists of a chassis plate 20 having front and rear pairs of supporting rollers 21 and 22 which are journaled on axles 23 carried by bearings 24 which depend from the under side of the chassis plate adjacent the four front and rear ends thereof. The rollers 21 and 22 afford antifriction means, by virtue of which the carriages may be movedover the inclined upper surface 7 of the panel 5 of the base member A, it being understood. that the carriages B and C arerespectively ac ranged in the guideways or channels 8 and 9. In order to guide and irsure a substantially true rectilinear movement of the carriages B and C in the respective guideways, each carriage is provided with means, which in the present instance consists of guide rollers 25 and 26, which are adapted to engage respectively with the faces 13 and 14 respectively of the intermediate and marginal strips 10, 11 and 12. The guide rollers 25 and 26 are mounted on axes perpendicular plates 20 and par- 14, and, as shown,

to the plane of the chassis allel to the faces 13 and or channels 8 and 9 may said axes are in the nature of shafts 27 which are journaled in bearings 28 carried by lon gitudinal supporting strips 29 which depend from the under sides of the chassis plates 20. Each carriage E and C further includes a foot supporting plaorin 30 which is of an appropriate size to accommodate the foot of the user on the upper surface 31 thereof. The foot supporting platform 30 is connected at one of its ends, preferably the forward end, to the chassis plate 20 for vertical swinging movement, by means of a hinge 32 or equivalent connection. Adjacent opposite free end, means is provided for supporting the platform 30 in relative angnlz'ir positions from its lowermost position in a parallel plane with the cl'iassisplate, and, as herein illustrated, said means is disclosed as a depending leg or stud 33 which is formed with a plurality of vertically spaced transverse apertures The chassis plate 20 is provided with a vertical slot 35 which accommodates the leg or stud 33, while the panel 5 of the base is correspondingly provided withlongitudinal slots 36, also serving to clear the studs or legs 33 oi. ti carriage platforms when they are adjusted to their lowermost positions. The apertures 34 are designed to selectively receive therethrough a pin 37 which is of a sullicirnt length to project beyond the opposite sides of the stud or leg 33 and engage with the upper surface of the chassis plates 20. In order to avoid. the possibility ofv accidental displacement of the pin 37, each chassis plate is provided with marginal upstanding ribs 38 which are transversely spaced apart a distance approximately equaling the length of the pin 37, so as to offer an obstruction to axial movement of the pin suflicient to allow for its displacement, it being understood that displacement of the pin can only be accomplished by raising the platform 30 to dispese the pin above the plane of the upper surfaces of the ribs 38.

: The apparatus further embodies means for connecting the carriages B and C so that they are compelled to move in opposite directions, the connection being such that when one carriage is at one limit of its movement, the other is at the other limit of its movement. The particular means of connection illustrated by way of example consists of a pair of cables 40 and 41, the former cable 4-0 having one extren'iity anchored as at 42 to the forward end of the carriage B and its other extremity anchored as at 43 to the forward extremity of the carriage C, while said cable is trained around a guide or sheave 44 which, as shown, is journaled on the intcrn'iediate strip 10 of the base. The other cable 41 has one extremity anchored as at 45 to the rear portion of the carriage C and its other extremity anchored as at 46 to the rear extremity of the carriage B,

the said cable being trained around a guide or sheave 47 which, as illustrated, is shown as journaled on the intermediate strip 10.

The forward face of the upstanding element or cleat is provided with a resilient buffer strip 48, with which the rear extremities of the chassis plates are adapted to engage,

whereby the shock of the engagement is absorbed and the sound incident thereto is deadened. This arrangement also provides means for limiting the rearward movement of one carriage and, incidentally, due to the connection between the carriages, limits the forward movement of the same.

In use and operation, the device is initially adjusted, both as to the inclination of the supporting base A and as to the relative position of the platforms 31 with respect to the chassis plates 20 of the carriages B 20 and C. The user, either with or without assistance, places one foot on the upper surface 31 of the platform of one carriage and the other foot on the upper surface of the platform of the other carriage. The user is cautioned to always put the first foot on the platform of the carriage which is at the lowerend of the incline or, in other words, that carriage which has its chassis plate abuting the element or cleat 15, and, likewise, in dismounting, the user must remove the first foot from the carriage which is at the uppermost end of the incline, it being apparent that otherwise a fall and possible injury may result. After the user l as prop-- erly mounted the apparatus, the foot on the uppermost carriage is moved rearwardly and, simultaneously, the foot on the lowermost carriage is moved forwardly when the user is facing the uppermost end of the device,

- the reverse being obviously true if the user is facing the lowermost end of the device. The use of the machine follows action of skating as practiced by a novice, and in starting, the user may be assisted to balancehimself by holding onto another person or object in close proximity to the device. The action at first may be slow and gradually increased as the user becomes accustomed to the apparatus. By facing in reverse directions, lar to ascending or descending an incline, and by adjusting thedevice the inclination maybe varied from a very slight incline to a pronounce l rade. It is also apparent that the platforn 30 of the carriages may be independently adjusted, so that one is disposed at a different inclination to the other, or one substantially horizontal and the other inclined. In use, as distinguished from walking, the jar and shock incident to the striking of the heel is entirely eliminated. The steady rythmic movement-s by use of the device make for an increased sup- )ly of blood and oxygen, arousing the heart and lungs to greater act vity, thus improving hip joint, the muscles of the lower closely the a the result willbe simicirculation and promoting assimilation "and elimination. Its regular use stretches and strengthens all the muscles and ligaments of the foot, leg and thighs, the back and the muscles of the abdomen. Preferably, the device will be used out of doors or adjacent an open window where a supply of fresh and uncontaminated air is available. When not in use, the device may be collapsed or folded to its minimum and will occupy but a small amount of space for either storage or transportation.
