Abstract

Exercise apparatus for exercising a part of the human body has a main frame with a base, an upright leg at the front and an inclined connecting leg extending between an upper part of the leg and the base. An exercising lever has a base, a forward portion extending upwardly and forwardly and a rear portion extending rearwardly and upwardly. At the upper end of the forward portion it is pivotally attached through a main frame. At the upper end of a rear portion is a transverse leg engaging member. Resistance means extends between the exercise lever and a main frame and provide resistance to the pivoting of the exercise lever. A support structure extends above the upper part of the main frame for support of the upper part of the body of a user.

Description

FIELD OF THE INVENTION

This invention relates to exercise apparatus and in particular, though not exclusively, to exercise apparatus for exercising the muscles at the upper part of a users legs.

BACKGROUND OF THE INVENTION

Various machines exist for exercising legs and other body parts. Typical of such machines is that described in U.S. Pat. No. 6,206,809. In this machine a user lies on their back on a pad, grasps arms extending up from the machine bed, above the users head. The user positions legs under a movable pad mounted on a pivotable framework. Pushing up by the legs on the movable pad pivots the framework against a resistance. The machine is primarily aimed at exercising abdominal muscles.
U.S. Pat. No. 5,439,433 relates to a “step climber” apparatus for exercising legs by the sequential pushing down on pedals by the user, in a stepping motion. Resistance is applied against moving of the pedals.

SUMMARY OF THE INVENTION

The present invention is primarily concerned with exercising the glute muscles and comprises a support frame for supporting a user in a more or less forward facing upright standing position while the user lifts one or the other of their legs upward and rearward against the resistance.
In a preferred embodiment of the present invention, an exercise apparatus has a main frame member composed of a base member, an upright leg attached to a front end of the base member and a connecting leg extending from the top end of the upright leg downwardly and rearwardly to connect at its bottom end at the base member. An exercising lever has a base, a rear upwardly extending portion extending rearwardly from a rear end of the base member and a forward portion extending upwardly and forwardly from a front end of the base member to the main frame at the other end of the upright leg. A leg engaging member extends transversely at an upper end of the rear upwardly extending portion. Resistance means for providing a resistance against pivoting of the exercising lever is positioned between the upper leg and the forward portion of the exercising lever. A support structure is provided above an upper part of the main frame, for the support of the upper body part of a user.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

Considering first FIGS. 1 and 2, the apparatus comprises a main support frame 10 having a bottom of base member 12 a forwardly positioned upright leg 14 and a connecting leg 16 extending rearward from the top end 18 of the leg 14, at 20 and then downward and rearwardly at 22 to connect at its lower end 24 to the base member 12 at 26. Transverse members 30 and 32 are positioned at each end of the base member 12 and a further transverse member 34 extends at an intermediate position.
In the embodiment illustrated, the portions 20 and 22 comprise parallel spaced apart members while the upright leg 14 is conveniently a single member.
Positioned on the top portions 20 is a pivot 40.
Extending between the two parallel spaced apart members of portions 20 and 22 is positioned an exercise lever 42. The lever 42 has three portions; a base 44, a rear outwardly extending portion 46 and an upwardly and forwardly extending portion 48. At its upper end 50 the forwardly extending portion 48 the exercise lever is pivotally attached to the pivot 40. The base 44 of the exercise lever extends through and into a slot 52 cut in the base member 12 of the main frame.
At the upper rearward end of the portion 46 is mounted a padded leg engagement member 54.
Conveniently the two transverse members 32 and 34 are covered by platform 56, shown in FIG. 1, a slot is also formed in the platform for movement of the exercise lever 42. Side panels can also be provided connecting the upper parts of the leg 14 and leg 16 as seen at 58 in FIG. 1. These panels are not shown in FIG. 2.
Attached to an intermediate point on the leg 14 is a bracket 64 to which is connected the lower end of a pneumatic cylinder 66. At its upper end the cylinder 66 is connected to a bracket 68 on the portion 48 of exercise lever 42.
In use a person stands on the platform 56 with legs astride the exercise lever 42. Leaning forward the user supports the upper body using the two spaced support members 70 mounted at the upper end of the portion 22 of the leg 16 of the main frame. (See particularly FIG. 1). If desired two handles 72 can be provided. The user then raises one leg, rearwardly but maintaining the leg straight so that the rear of the ankle engages the padded member 54. Lifting of the member 54 causes pivoting of the exercise lever 48 about pivot 40 against resistance of the cylinder 66.
Depending upon the size of the user, dimensions, etc., can vary. However, it has been found that certain dimensions provide a generally universal apparatus. For example, the length of the main frame—dimension “A” FIG. 2—is about 50″. The height “B” is about 34″. The vertical height of the exercising lever, from base to pivot point—“C”—is about 43″.
The slot 50 is about 18″ long and is positioned about 21″ from the leg 30. The base member extends about 9″ from the rear end of the slot.
Various angles have been determined to give optimum results. Thus, the angles A and F at the junctions between base 44 and portions 46 and 48 are about 136° and 123° respectively. The angle G between the base member 12 and portion 22 of the main frame is about 56°. The support members 70 are mounted such that an axis normal to the support members extends at about 125° through the top portion 20 angle H in FIG. 2. The transverse members are conveniently made 22″ long but this is only critical from the stability concern for the apparatus.
Conveniently the various members of the frame and exercise lever, and other parts, are tubular form, and are metal, although other forms of structure can be used.
While a (pneumatic) hydraulic cylinder 60 has been shown and described, other forms of resistance member can be used. Typical operations are springs, a pulley and weight arrangement, a pneumatic cylinder, rubber or other elastic materials. Means may be provided for variably adjusting a resistance produced by the resistance member. For example, means may be provided for varying the effective overall length of the cylinder assembly 66. As an alternative one or both of the attachment positions of the cylinder to the upright leg 14 and to the exercise lever 42 can be varied.
