Taylor Attorney, Agent, or Firm-Hibben, Noyes & Bicknell 5 ABSTRACT An exerciser device is provided for exercising various parts of the body, particularly the back and legs of a person using the device. The exerciser device comprises a back support on which a person may lie and a ladder member having an end extending over the person. The device may further comprise an upright support for supporting the extending end of the ladder member. The extending end of the ladder member is adjustably connected to the upright support and the other end of the ladder member is pivotally connected to the back support. The ladder member has variably spaced rungs extending along its length on which a person may walk his legs to increase the flexibility and movement of his back and legs.
9 Claims, 4 Drawing Figures EXERCISER DEVICE This invention relates to an exerciser device, and more particularly to an exerciser device for exercising various parts of the body, particularly the back and legs.
As is well known, a person loses flexibility in his back and legs due to inadequate exercise, injury, disease or simply aging. Frequently, moderate exercise of the back and legs can restore the lost flexibility.
The exerciser device of the present invention can be used by a person to restore such lost flexibility, and comprises a back support on which a person may lie and a ladder member having an end extending over the person. In the present instance, the device also includes an upright support for supporting the extenting end of the ladder member which is adjustable to accommodate different size persons. The ladder member has variably spaced rungs along its length on which a person may walk his legs to increase the flexibility and movement of his body, particularly of his back and legs.
It is the primary object of the present invention to provide an exerciser device for performing mild or moderate exercise to increase the flexibility of a persons body, particularly of the back and legs.
Another object of the exerciser device of the present invention is to provide an exerciser device that permits a type of exercise which can be gradually increased in magnitude over a period of time so as to extend and increase the flexibility of the back and legs of a user.
While the exerciser device of the present invention has been designed primarily for such type exercise, it has the advantage that it can also be conveniently used to exercise other parts of the body.
Another advantage of the exerciser device of the present invention is that it may be easily disassembled and collapsed into a relatively small space either for storage or transportation.
These and other objects and advantages of the exerciser device of the present invention will become apparent from the following description and the accompanying figures of the drawing wherein:
FIG. 1 is an elevational view of an exerciser device of the present invention, portions of the device being shown in alternate positions in dashed lines;
FIG. 2 is a top view of the exerciser device shown in FIG. 1;
FIG. 3 is an end view of the exerciser device shown in FIG. I; and
FIG. 4 is a cross-sectional view taken along the line 44 of FIG. 1.
The exerciser device of the present invention is illustrated in FIG. 1, and comprises a back support 12 and ladder member 14. In the present instance, the device 10 also includes an upright support 16 for supporting the ladder member 14.
The back support 12 is generally horizontal with its head end slightly higher than its opposite end, thus making it easier to lie down and particularly to get up. The back support 12 includes two tubular elements 18, each having a straight, central section 20 joining a pair of generally vertical leg sections 22 and 24 at the head end and opposite end of the back support 12, respectively. The elements 18 are made of one-inch square aluminum tubing with an eighth-inch sidewall thickness. As is shown in FIG. 2, the two elements 18 stand in vertical planes parallel to each other and are spaced approximately 22 inches apart. The back support 12 further includes a top 26, in this instance of plywood, which is secured to the central sections 20 of the elements 18. The plywood top 26 is secured to sections 20 with a plurality of screws 28 and nuts 30. Both the plywood top 26 and central sections 20 of the elements 18 have appropriate openings to receive the screws 28. As is shown in FIG. 1, the legs 22 are longer than the legs 24 to incline the central sections 20 and plywood top 26, with the head end above the other end.
A central cut-out 32 (FIG. 4) is provided in the head end of the plywood top 26 to receive the head of a person using the exerciser device 10. If desired, the top 26 may be fitted with a cushion or pad 34. The pad 34 could extend across the cut-out 32 to help support the head of the user, as shown in FIG. 1.
The ladder member 14 is secured at its lower end to the head end of the back support 12. The ladder member 14 rises initially away and upwardly from its lower end and then curves up over the back support 12, terminating above the opposite end of the back support 12. The curve of the ladder member 14 is such that the ladder member generally lies on the locus generated by a person lying on the back support 12 and pivoting an extending foot from a vertical position above his buttocks to a nearly horizontal position above his head. The ladder member 14, preferably, comprises two side rails 36 having a plurality of rungs 41 through 48, inclusive.
As can be appreciated, the above-mentioned locus will vary with the size of the person, and to accommodate this variation the ladder member 14 is adjustable. To this end, the side rails 36 of the ladder member 14 are pivotally secured to the lower ends of the legs 22 of the back support 12. The ladder member 14 has a spreader 50 located between the lower ends of the side rails 36 and the adjacent associated legs 22 of the back support 12. The spreader 50 is a piece of one-half inch diameter aluminum tubing. A threaded rod 52 (FIG. 3) extends through openings in the legs 22 of the back support 12, through the lower ends of the side rails 36 and through the spreader 50. Nuts, such as acorn nuts 54, engage the ends of the threaded rod 52 to hold the legs 22 against the side rails 36 and to hold the side rails tight against the ends of the spreader 50. Thus, the ladder member 14 is held in pivotable relation to the back support 12 by the spreader, rod and nut assembly.
The side rails 36 extend initially outwardly straight from their lower ends for about 16 inches and then bend about 40 toward the opposite end of the device 10, as indicated at 55. The side rails 36 then bend, on about a 35 inch radius, along an arc for as indicated at 57, and terminate in a 6 inch straight section at the opposite end, as indicated at 59. As is shown in FIGS. 2 and 3, the side rails 36 are offset inwardly toward each other just above their lower ends so as to provide clearance near the opposite ends for the upright support 16. The side rails are offset or bent inwardly toward each other and then bent straight again, as generally indicated at 56.
The ladder member 14, in this instance has the eight rungs 41 through 48, inclusive, which are unequally spaced along the side rails 36 so as to provide convenient exercise increments. Rungs 41 through 45 near the head end are spaced closer together than the other rungs 46 through 48 near the opposite end since it is more difficult for a person to reach rungs 41 through 45 with his feet. The lowest rung 41 is located slightly above the 40 bends (55) in the side rails 36, the next four rungs, 42 through 45, inclusive, are spaced 6 inches apart, and the upper three rungs 46 through 48, inclusive, are spaced nine inches apart.
Each of the rungs 41 through 48 comprises a length of round half-inch tubing aluminum having an eighthinch side wall. The side rails 36 are drilled to receive one-quarter inch threaded rods 60 (FIG. 4); each rod 60 extends through one side rail 36, through one of the rungs 41 through 48 and through the opposite side rail 36. The ends of the threaded rods 60 receive nuts, such as acorn nuts 62, to secure the rungs and side rails of the ladder member together.
While the ladder member 14 and back support 12 could be constructed to be free standing, in this instance, the upper end of the ladder member 14 is secured to the upright support 16. The upright support 16 also provides additional leg supports for the middle of the back support 12 and provides convenient handholds while getting on, using or getting off the device. The upright support 16, in this instance, comprises a pair of tubes 64 made of similar material as that of the tubular elements 18 and side rails 36. The tubes 64 have straight lower sections 63, then bend approximately 60 toward the head end, indicated at 65 and terminate in final upper sections 67 of lengths of about inches bent on a 50 inch radius. As is shown in FIG. 3, the tubes 64 forming the upright support 16 are also offset, the tubes 64 first being bent inwardly and then again being bent straight, as indicated at 66.
The upright support 16 is removably secured to the back support 12. As shown in FIG. 2, aligned openings 70 and 72 are provided in the central sections and in the lower sections 63 of the tubes 64, respectively. These openings 70 and 72 receive threaded fasteners 74 which in turn receive wing nuts 76 to hold the tubes 64 in position. An almost square (1 inch X 1- 1/16 inch) opening 78 is provided in each side of the top 26 to accommodate the tubes 64. The openings 78 are somewhat longer than the cross-sectional size of the tubes 64 to accommodate movement of the tubes.
The upper end of the ladder member 14 is adjustably and removably secured to the upright support 16. In the upper end of each of the tubes 64 forming the upright support 16 are a plurality of holes 80, in this instance seven being illustrated. Each of the holes 80 passes completely through the tube 64 and can be aligned with single openings 82 (FIG. 2) in each of the side rails 36 of the ladder member 14. The openings 82 in the side rails 36 of the ladder member are between the sixth rung 46 and seventh rung 47. The openings 80 and 82 in the side rails 36 and tubes 64, respectively, receive fasteners, such as threaded bolts 84, the bolts 84 being held at their opposite ends by wing nuts 86. By arranging the ladder member 14 so that one set of openings 82 in the side rails 36 are aligned with the openings 80 in the tubes 64, the ladder member 14 can be adjusted to various positions to compensate for different size users, as is shown in FIG. 1 in dashed lines at 14 and 14".
In using the exerciser device 10, the user lies down on his back with his head located at approximately the cut-out 32. The user then raises his legs to engage, perhaps, the last rung 48 which is approximately above his buttocks. The user then walks his legs along the rungs 41 through 48 toward his head as far as he can go without undue strain. As a person walks his legs toward the rungs at the head end, his lower back is caused to bend and his buttocks lift somewhat off the back support 12. This exercise limbers up both the legs and back and permits the user to gradually increase the amount of flexibility in his legs and back. At first a person may be able to walk on only the eighth, seventh and sixth rungs 48 through 46, but he will eventually be able to work his way to the fifth rung 45 and, perhaps, the fourth rung 44 or third rung 43. A particular flexible person may be able to walk his legs all the way to the first rung 41.
Other exercises can be performed on the device 10. A person lying on the back support 12 could chin himself on one of the rungs. A person with his legs bent at the knees could hook his heels on the sixth rung 46 and then pressing his hands against his knees, straightening his knees and legs. The user only need exercise his imagination to determine other exercises which can be performed on the device 10.
For ease of storage or transportation the exerciser device 10 can be knocked down into a relatively small space. To disassemble the device 10, the fasteners 84 and nuts 86 are removed so that the ladder member 14 can be folded down with the back support member 12. Should further disassembly be desired, the fasteners 74 and nuts 76 can be removed and the upright support 16 can be removed from the openings 78 in the top 26. Also, the rod 52 and nuts 54 can be removed so the ladder member 16 can be disconnected from the back support 12.
