Description
Background of the Invention
The instant invention relates generally to gymnastic equipment and more specifically it relates to a roller skate exercise device.
Numerous types of gymnastic equipment have been provided in prior art that are adapted to have separate foot engaging members reciprocating on parallel guide tracks, so that people using the gymnastic equipment can exercise their legs. For example, U.S. Pat. Nos. 3,941,377 to Lie; 4,434,981 to Norton; 4,659,077 to Stropkay; 4,960,276 to Feuer et al.; 5,000,442 to Dalebout et al. and 5,039,088 to Shifferaw all are illustrative of such prior art. While these units may be suitable for the particular purpose to which they address, they would not be as suitable for the purposes of the present invention as heretofore described.
Summary of the Invention
A primary object of the present invention is to provide a roller skate exercise device that will overcome the shortcomings of the prior art devices.
Another object is to provide a roller skate exercise device that will simulate the motion of cross country skiing with roller skates, so that a person can work out day and night in the safety of their home to build up their muscles.
An additional object is to provide a roller skate exercise device in which the person can utilize ski poles in conjunction with the device for better balance.
A further object is to provide a roller skate exercise device that is simple and easy to use.
A still further object is to provide a roller skate exercise device that is economical in cost to manufacture.
Further objects of the invention will appear as the description proceeds.
To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.

Detailed Description of the Preferred Embodiments
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1 through 10 illustrate a roller skate exercise device 12, which consists of a platform 14 having a top surface 16 to support a pair of roller skates 18 worn by a person 20. Components 22 are for permitting the roller skates 18 to slide in opposed reciprocating motions on the top surface of the platform 14, so as to simulate cross country skiing.
The slide permitting components 22 include a pair of straps 24, in which each strap 24 fits about an ankle 25 of the person 20. Elements 26 are for applying resistance to the straps 24 between a front portion 28 and a rear portion 30 of the top surface 16 of the platform 14.
A first cross support 32 is mounted to a rear portion 34 of a bottom surface 36 of the platform 14. A second cross support 38 is mounted to a front portion 40 of the bottom surface 36 of the platform 14. The first cross support 32 and the second cross support 38 can horizontally elevate the platform 14 from a floor 42. A fold out leg 44 is hinged at 46 to the second cross support 38, so that the fold out leg 44 can angularly elevate the platform 14 from the floor 42.
As best seen in FIGS. 5 and 6, each strap 24 is adjustable and contains a belt portion 48 with a buckle 50 attached to a first end 52 of the belt portion 48. Mating hook and loop pile fasteners 54 are attached to a second end 56 of the belt portion 48. The second end 56 can fit through the buckle 50 and be folded over to be held thereto by the mating hook and loop pile fasteners 52.
The platform 14 can have a first set of spaced apart holes 58 in a parallel arrangement along a first side 60 and a second set of spaced apart holes 62 in a parallel arrangement along a second side 64. The person 20 can use a pair of ski poles 66 inserted into two holes 58, 62 for better balance. The platform 14 can also have a first handle slot 67 between the first set of spaced apart holes 58 and the first side 60 and a second handle slot 68 between the second set of spaced apart holes 62 and the second side 64, so that the platform 14 can be carried by the handles slots 67 and 68.
The resistance applying elements 26 in FIGS. 1 through 3, are a pair of short elastic resistance cords 70a, 70b. The first short cord 70a is connected between the first strap 24 and the front portion 30 of the first strap 24 and the front portion 30 of the top surface 16 of the platform 14. The second short cord 70b is connected between the second strap 24 and the rear portion 28 of the top surface 16 of the platform 14. A pair of long elastic resistance cords 72a, 72b are also provided. The first long cord 72a is connected between the first strap 24 and the rear portion 28 of the top surface 16 of the platform 14. The second long cord 72b is connected between the second strap 24 and the front portion 30 of the top surface 16 of the platform 14.
A hook 74 is attached to each end of the short cords 70a, 70b and the long cords 72a, 72b. Each belt portion 48, as best seen in FIGS. 5 and 6, has at least two loops 76 formed thereon. One loop 76 will receive one hook 74 from the short cord 70a, 70b, while the other loop 76 will receive another hook 74 from the long cord 72a, 72b.
Four eyelet screws 77 are threaded in spaced apart relationships transversely into the front portion 28 of the top surface 16 of the platform 14. The third and fourth eyelet screws 77 are threaded in spaced apart relationships transversely into the rear portion 30 of the top surface 16 of the platform 14. The eyelet screws 77 will receive the hooks 74 from the short cords 70a, 70b and the long cords 72a, 72b.
A modified roller skate exercise device 12a, as shown is FIG. 9. The resistance applying elements 26a include four elongate nonelastic resistance cords 78. The first and second cords 78 are each connected between one strap 24 and a front portion 28 of the top surface 16 of the platform 14. The third and fourth cords 78 are each connected between one strap 24 and a rear portion 30 of the top surface 16 of the platform 14.
Four reel tension assemblies 80 are also provided, one of which is best seen in FIG. 10. The first and second reel tension assemblies 80 are mounted in spaced apart relationships transversely onto the front portion 28 of the top surface 16 of the platform 14. The third and fourth reel tension assemblies 80 are mounted in spaced apart relationships transversely onto the rear portion 30 of the top surface 16 of the platform 14. The reel tension assemblies 80 will store therein and dispense therefrom the cords 78.
Operation of the Invention
To use the roller skate exercise device 12 the person 20 wearing the roller skates 18 steps onto the top surface 16 of the platform 14, with the straps 24 attached to his/her ankles. The resistance cords 78 or 70a, 70b, 72a, and 72b are then attached to the straps 24. The roller skates 18 can now slide in opposed reciprocating motions on the top surface 16 of the platform 14, to simulate cross country skiing. The ski poles 66 can each be inserted into one hole 58, 62 in the platform 14, so that the person 20 can have better balance.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing from the spirit of the invention.
