  Portable exercise machineUSPTO Application #: 20080090706Title: Portable exercise machine Abstract: A portable exercise device having an elongated tube with a pair of bolsters or handles fixedly attached to each end thereof. A third pair of bolsters is positioned intermediate the ends of the elongated tube and is slidably mounted on the tube in a reciprocatory movement relative to the pairs of bolsters at each end of the tube. Resistance elements are connected between the third pair of bolsters and the tube to resist the pushing or pulling of the third pair of bolsters. The machine is used for exercising a person's inner and outer thighs, the leg and abdominal muscles. A stand is provided for supporting the exercise machine when performing a bun kick.

BACKGROUND OF THE INVENTION [0001]Various portable exercising devices have been proposed for exercising various muscles in a person's body; such as, the bun and thigh muscles. Many of these devices have been characterized by their limited portability due to the construction and weight of the device and the relatively laborious process of varying the resistive force built into the device. SUMMARY OF THE INVENTION [0002]After considerable research and experimentation, the exercise machine of the present invention has been devised to overcome the disadvantages experienced in prior portable exercising devices, whereby the machine is relatively light to facilitate its portability and the resistance forces can be easily adjusted to accommodate various users. The portable exercise device of the present invention comprises, essentially, an elongated tube having a pair of bolsters or handles fixedly attached to each end thereof. A third pair of bolsters is positioned intermediate the ends of the elongated tube and is slidably mounted on the tube in a reciprocatory movement relative to the pairs of bolsters at each end of the tube. Resistance elements are connected between the third pair of bolsters and the tube to resist the pushing or pulling of the third pair of bolsters. [0003]The exercise machine is detachably connected to a stand or cradle for supporting the exercise machine on the floor to facilitate the exercising of the buttock muscles. BRIEF DESCRIPTION OF THE DRAWINGS [0004]FIG. 1 is a perspective view of the portable exercise machine of the present invention supported by a floor cradle; [0005]FIG. 2 is a bottom perspective view of the exercise machine as shown in FIG. 1; [0006]FIG. 3 is a vertical perspective view of the exercise machine removed from the floor cradle; [0007]FIG. 4 is a side elevational view of the exercise machine as shown in FIG. 3; [0008]FIG. 5 is a top plan view of the exercise machine as shown in FIG. 3; [0009]FIG. 6 is a sectional side elevational view of the exercise machine taken along line 6-6 of FIG. 5; [0010]FIG. 7 is a sectional side elevational view of the exercise machine shown in FIG. 6, showing the third pair of bolsters moved to an end of the tube to tension all of the resistance elements providing maximum resistance; [0011]FIG. 8 is a sectional side elevational view of the exercise machine similar to FIG. 6 showing only one resistance element connected in an operative position to provide a more reduced resistance than that shown in FIG. 6; [0012]FIG. 9 is a sectional side elevational view of the exercise machine shown in FIG. 8 showing the third pair of bolsters pushed to the end of the tube to tension the single resistance element; [0013]FIG. 10 is a side elevational view of the machine being used for a leg press; [0014]FIG. 11 is a side elevational view of the machine being used for exercising a person's abdominal muscles; [0015]FIG. 12 is a side elevational view of the exercise machine and its associated floor cradle being used for a bun kick; [0016]FIG. 13 is a top plan view of the exercise machine of the present invention being used for exercising a person's inner thigh; and [0017]FIG. 14 is a top plan view of the exercise machine used for exercising a person's outer thigh. DESCRIPTION OF THE PREFERRED EMBODIMENT [0018]Referring to the drawings and more particularly to FIG. 1, the portable exercise machine 1 of the present invention comprises an elongated tube 2, elliptical in cross-section, as shown in FIG. 5, and having a pair of bolsters or handles 3 and 4 fixedly attached to each end thereof. A third pair of bolsters or handles 5 is positioned intermediate the handles 3 and 4 and is slidably mounted on the tube 2 in a reciprocatory movement relative to the pairs of bolsters 3 and 4. [0019]The movable bolsters 5 are connected to the tube 2 by means of a transversely extending spindle 5a extending through elongated slots 2a provided in the sidewalls of the tube 2. As will be seen in FIGS. 6 and 7, the spindle 5a is connected to a carriage 6 slidably mounted in the tube 2. [0020]The carriage 6 comprises a piston having a plurality of axially extending partitions forming chambers 6a. One end of each chamber 6a communicates with a respective socket 6b provided in one end of the carriage 6 and the opposite end of each chamber communicates with a slot 6c formed by radially inwardly and outwardly extending flanges 6d and 6e. Elastic straps 7 are contained within the tube 2 to provide the desired resistance to the movement of the bolster 5 from the position shown in FIG. 6 to the position shown in FIG. 7. Each elastic strap 7 has a collar 7a fixedly connected to one end thereof and received in a respective socket 6b in the carriage 6. The opposite end of each strap 7 also has a collar 7b fixedly connected thereto. A transversely extending partition 8 is fixedly connected to the interior wall of the tube 2 and is provided with slots 8a, as shown in FIG. 3, for receiving the corresponding end portion of a respective strap 7 and for providing a shoulder for releasably holding the collar 7b.
