Description

FIELD OF THE INVENTION

The present invention relates to portable sets of exercise apparatus that can be configured in different combinations to allow the performance of a wide range of exercises for exercising various of the user's muscle groups.

BACKGROUND OF THE INVENTION

Current exercise apparatus that permits a user to exercise of wide variety of muscle groups is generally relatively massive and heavy and intended for use in a fixed location. Various types of portable exercise apparatus are known that permit a user to perform a limited range of exercises, such as push-ups or abdominal muscle crunches, that exercise only one or a few portions of the body. In order for a user to achieve of full body workout using available portable exercise apparatus, a variety of different independent types of apparatus would be required that, in total, would the bulky and heavy and not practicably portable.
It is also generally not practically possible with available portable exercise apparatus to controllably vary the intensity of the exercise being performed. For instance, a typical apparatus intended for conditioning the abdominal muscles consists of a wheel rotatably mounted at the center of a shaft, with handgrips at either end of the shaft. The user grasps the apparatus by the handgrips and rolls the wheel back and forth along the floor, extending the arms and upper body as a wheel is rolled forward. The apparatus is thus inherently unstable, and once the wheel has been rolled forward and away from the body, the instability makes it difficult to roll it back to the starting position. Additionally, it is easy to allow the wheel to roll too far forward, which puts undue stress on the user's lower back.

SUMMARY OF THE INVENTION

In accordance with the present invention, applicant provides exercise apparatus comprising a set of units that can be configured in various combinations for allowing the user to perform different exercises targeting different muscle groups of the body, thereby to achieve a full body exercise. The apparatus includes a pair of push-up units, each of which includes a handle mounted to a base, a pair of kneepad units having a resilient upper surface, and a pair of roller wheel units, each having a plurality of roller bearings distributed about its bottom surface for providing a stable support that permits the roller wheel units to be rolled in any direction on the floor. The roller wheel units, push-up units and kneepad units further includes a mechanism for stablely but releasably mounting either a push-up unit or a kneepad unit on the top surface of a roller wheels unit so that the combined units can roll in any direction. In a preferred embodiment of the invention, the mounting mechanism includes a vertical shaft extending from the center of the top surface of the rollers wheels unit. Corresponding vertical holes are preferably provided in the bases of the push-up units and the kneepad units for mounting them on the shafts. The shafts are preferably shorter than the thickness of the kneepad units and the bases of the push-up units so that the top of the shaft is recessed below the surface of the base of the push-up unit and the kneepad unit when they are mounted on a roller wheel unit.
In accordance with one embodiment of the present invention, the base of each push-up unit preferably includes a lower part and an upper part which is rotatably mounted on the lower part so that the handle can be rotated by the user when the base of the push-up unit is resting on the floor. In accordance with a preferred embodiment of the invention, the handle of each push-up unit is detachable from the base thereof.
In accordance with a further embodiment of the invention, the apparatus also includes a pair of handle shafts each having of central gripping surface portion and extending portions on either end sized to fit the holes in the kneepad units and the base of the push-up units, so that the kneepad units can be mounted on either end of one of the handle shafts and the bases of the push-up units can be mounted on either end of the other handle shaft, optionally, in each case, with additional weights, to form dumbbells. Removable clamps are provided to hold the apparatus mounted on the handle shafts in place during use.

DETAILED DESCRIPTION OF EMBODIMENTS

Referring now to FIG. 1 of the drawings, there is illustrated a push-up unit 11 in accordance with a preferred embodiment of the invention that includes a base 13 consisting of a lower part 15 having a substantially flat bottom and vertically extending cylindrical sides and an upper part 17 that is rotatably mounted in the lower part 15. The handle 19, which includes a hand grip portion 21 and downwardly extending connector portions 23 on either end of the hand grip portion 21 is fixedly mounted on the upper part 17. The hand grip portion 21 preferably has a resilient gripping surface made of, e.g., a rubberized or elastomeric material. As seen in FIG. 1 a, a pair of mounting studs 25, each having a T-shaped cross-section, extend from the bottom surface 27 of each connector portion 23 for removably mounting and locking the handle 19 to the upper part 17 by engagement in the corresponding slots 29 in the surface of the upper part 17. A vertically extending cylindrical aperture 31 extends fully through the center of the base 13 for mounting the push-up unit 11 on a roller wheel unit as described below.
FIG. 1( b) is an exploded view showing the internal structure of the push-up unit 11 of the illustrated embodiment of the invention. A rotatable bearing 33 includes a lower member 35 that is affixed to the bottom of the base 15, e.g., by being bolted thereto, and an upper member 37 that is rotatably mounted within the lower member 35. Ball bearings, not shown, in the interior peripheral area of the lower member 35 facilitate the rotation of the upper member 37. The upper part 17 of the base 13 is attached to the upper member 37 of the bearing 35 for rotation therewith by four downwardly extending legs 39, three of which are visible in FIG. 1 b, such legs having threaded lower ends 41 that mate with and extend through corresponding holes 43 in the upper member 37, and clamped thereto by bolts (not shown) screwed onto the threaded portions 41. The structure can be made stronger, if necessary, by providing a rigid supporting web connecting the legs 39.
FIG. 2 shows a kneepad unit 51 in accordance with the illustrated embodiment of the invention, which includes a base 53, a resilient upper surface 55, and a central vertical aperture 57 that extends fully through the kneepad unit 51 for mounting it on a roller wheel unit as described below. The resilient upper surface 55 may, for instance, be formed of an elastomeric pad adhered to the base 53.
FIGS. 3 and 4 are bottom and top views, respectively, of a roller wheel unit 61 in accordance with the illustrated embodiment of the invention. The plurality of bearing members 63, in the illustrated embodiment 11, are positioned around the periphery and at the center of the bottom of the roller wheel unit 61 for providing stable support thereto while permitting movement thereof in any direction on the floor on which the roller wheel unit 61 rests. Each of the bearing members 63 includes a ball bearing 65 that is freely rotatable in a housing 67. A cylindrical shaft 69 extends upwardly from the center of the top surface of the roller wheel unit 61, such shaft being sized to fit slidably and preferably snugly in the apertures 31 and 57 in the push-up units 11 and kneepad units 51 for securely mounting and positioning a push-up unit 11 or kneepad unit 51 on a roller wheel unit 61. The length of the shaft 69 is such that its top surface is below the surface of the base 13 of the push-up unit 11 or kneepad unit when they are mounted on a roller wheel unit 61.
The central shaft 69 could be replaced by any structure that securely mounts and positions a push-up unit 11 or a kneepad unit 51 on top of a roller wheel unit 61. For instance, the roller wheel unit could be provided with an upwardly extending collar around its periphery into which a push-up unit 11 or kneepad unit 51 could be set. Such a collar could, for instance, be formed as a rigid cylindrical member, or could be formed of flexible band that is drawn tight around the base of the push-up unit 11 or kneepad 51 by means of clamp. Alternatively, for example, a plurality of shafts or studs could be provided on the top surface of the roller wheel unit 61 that would engage in corresponding holes or slots in the bottom surface of a push-up unit 11 or kneepad unit 51.
FIGS. 5 and 6 show a kneepad unit 51 and push-up unit 11 respectively mounted on roller wheel unit 61. In this arrangement, the combined units are able to roll freely in any direction on the floor while the user is employing them in the performance of various exercises.
As seen in FIGS. 7 and 8, the kneepad units 51 and bases 13 of the push-up units 11 can be mounted on shafts 71, optionally with additional weights 73, to form dumbbells. Each of the shafts 71 includes a central handgrip portion 75 and extending end portions 77 on which the weight members are mounted. The weight members are held in place by a clamping structure such as the washer members 79 that are threaded onto the extending end portions 77.
FIGS. 9 through 12 illustrate two of the many different exercises that can be performed using the apparatus of the present invention. FIG. 9 shows the starting position of a first exercise, referred to as a circular push-up, in which the push-up units 11 are mounted on the roller wheel units 61. The user kneels on the kneepads 51 and grasps the handles 19 of the push-up units 11 with hands aligned with shoulders and spread apart. The user then rolls the hands forward along a generally semicircular path, extending the arms and upper body and bringing the hands together at the full extension as seen in FIG. 10, and then returns to the starting position by rolling the push-up units 11 back towards the knees retracing a similar generally semicircular path. This motion can then be repeated a desired number of times. The muscles worked in this exercise include the upper and lower abdominal, lower back, latissimus dorsi (lats) and chest muscles, the triceps, and shoulders. The intensity of the exercise can be varied by varying the degree of initial spread of the hands and amount of forward extension of the arms and upper body. The intensity can also be increased by extending the legs and placing the feet on the kneepads 51 rather than the knees.
FIG. 11 shows the starting position of a second exercise, referred to as an extended leg reverse crunch, in which the kneepads 51 are mounted on the roller wheel units 61. The user grasps the handles of the push-up units 11 and places his feet on the kneepads 51 with the body and arms extended, as seen in FIG. 12. The user then draws the roller wheel mounted kneepads forward towards his hands keeping his knees extended, and then returns to the starting position. The muscles worked in this exercise include the upper and lower abdominal, pectoral, lower back and hamstring muscles and quadriceps and triceps.
The apparatus of the present invention can be used to perform a large variety of other exercises, such as those listed in the following table, in addition to those illustrated in FIGS. 9 through 12. The list of exercises in the table is only illustrative is not intended to be exhaustive.
