The present application is a continuation-in-part of the copending application entitled "Exercise Unit," Serial No. 08/540,175, filed October 6, 1995 by David Richmond. <br><br>
Field of the Invention <br><br>
10 This invention relates to an exercise unit. More particularly, the invention relates to an improved exercise unit which includes a minimal number of parts and which is light in weight and compact and which is efficient in exercising the user's gluteus muscles. <br><br>
Background of the Invention <br><br>
15 Exercise units are now proliferating in view of the public's interest in providing sound and healthy bodies and in enhancing visual appearances. As exercise units proliferate, they are increasingly heavy and complex. They have also become increasingly expensive and immobile. Because of these factors, there is a tendency for the public to become increasingly wary of the claims made by the marketers of the exercise units concerning the benefits and advantages of 20 such exercise units. <br><br>
This invention provides an exercise unit which is light in weight and compact. It is also highly mobile so that it can be conveniently packed for transportation and storage. It includes a minimal number of parts and is inexpensive. It is primarily used to exercise the muscles in the lower part of the user's body and particularly the gluteus muscles. Even though it is light, 25 compact, mobile and relatively simple in construction and operation, it still operates efficiently in exercising the user's muscles. <br><br>
Summary of the Invention <br><br>
In one embodiment of the invention a footrest made firom a suitable material such as a 30 polyolefin may have a tear drop configuration defined by a progressively increasing width or may have a cylindrical shape in cross section. An aperture is provided through the footrest and a hollow rod is extended through the aperture. A stretchable member made from a suitable material such as a latex extends through the hollow rod in a closed loop. The user disposes the stretchable member around his thighs and feet and then reclines on a floor with the user's back 35 on the floor. The user then rests his feet on the floor against the footrest while reclining with his back on the floor. The user then exercises by alternately arching the user's back upwardly to <br><br>

'314403 <br><br>
29990/GSL/A490 <br><br>
stretch the stretchable member and then collapsing the user's back against the floor-to release such stretching. <br><br>
5 In a second embodiment, a belt in the form of a first closed loop is attached to the opposite ends of the stretchable member to define with the rod and the stretchable member a second closed loop larger than the first closed loop. The belt may envelop the user's waist. The stretchable member extends between the user's waist and the bottom of the user's feet. The user exercises by disposing both feet on the footrest and alternately rising to a substantially upright 10 portion from a crouching position to stretch the stretchable member and then bending the user's knees to relieve any stretching of the stretchable member. In yet another embodiment, a user interface comprises an arcuate section with handlebars supported above the footrest by arms. In this embodiment the weight of the arcuate section may be adjusted by adding a material such as water or sand to the arcuate section's interior. Further weight adjustment may be provided by 15 two handlebars that receive removable weights. <br><br>
In a preferred embodiment the exercise device includes a footrest having a number of differently anc 1 surfaces for placement of the user's feet while exercising. A pair of rotatable arms are attached to the footrest and a handle is positioned over the arms and is resistively attached to the device by an elastic cord which extends from the handle through the arms and the 20 foot rest. <br><br>

Detailed Description of the Invention <br><br>
10 One embodiment of an exercise unit is shown in FIGs. 1 and 2 and is generally indicated at (10). The exercise unit includes a footrest (12) preferably having a substantially tear drop configuration in section. The footrest (12) may be made from a suitable material such as a polyolefin. The tear drop configuration provides the footrest (12) with an increasing thickness at progressive positions along the length of the footrest. At a position near the thick end of the 15 footrest (12), an aperture (14) extends through the footrest. Although the footrest (12) is shown as preferably having a tear drop configuration in section, it will be appreciated that the footrest may have other configurations in section. For example, the footrest (12) may have an annular configuration in section. <br><br>
A hollow rod (16) extends through the aperture (14) in the footrest (12). A member (18) 20 made from a stretchable material such as a latex extends in a" closed loop through the aperture (14). As shown in FIG. 1, the footrest (12) is disposed on the ground such that the thick end of the footrest is disposed away from the user. This causes the footrest (12) to be inclined and the bail and heel portions of the user's feet to be disposed on the footrest when the user is lying on a floor (20) with the user's back disposed on the floor. <br><br>
25 The user then bends the user's legs and disposes the member (18) so that the member rests on the user's thighs and envelopes the user's feet. This is shown in FIG. 1. The user then arches the user's back upwardly as shown in FIG. 2 while maintaining the user's feet firmly planted on the footrest (12). This causes the member (18) to become stretched. As a result, the user has to exercise the user's leg muscles to stretch the member (18). <br><br>
30 When the user has arched the user's back to the position schematically shown in FIG. 2, <br><br>
the user returns the user's back to the position against the floor (20) as shown in FIG. 1. This causes the constraint on the stretchable member (18) to become released. By moving the user's body alternately between the positions shown in FIGs. 1 and 2, the user is able to provide an efficient exercise of the user's back and leg muscles. <br><br>
35 FIGs. 3 and 4 illustrate an exercise unit, generally at (30), constituting a first alternative embodiment of the invention. The embodiment (30) is similar to the embodiment (10) in the inclusion of the footrest (12) and the rod (16) extending through the aperture (14) in the footrest. <br><br>
-3- <br><br>
314403 <br><br>
29990/GSL/A490 <br><br>
It is also substantially similar to the embodiment (10) in the disposition of a stretchable member (32) through the aperture (14) in the rod (16). However, the opposite ends of the stretchable 5 member (32) are in turn attached to a member (38) forming a closed loop. The attachment of the stretchable member (32) to the member (38) is at the opposite ends of the closed loop. The member (38) may also be made from a stretchable material such as latex. <br><br>
When the user desires to use the exercise unit (30), the user disposes the member (38) around the user's waist and stands on the floor (20) with the soles of the user's feet on the footrest 10 (12). The user then alternates between a crouching portion as shown in FIG. 3 and a substantially upright portion as shown in FIG. 4. When the user raises the user's body to substantially the upright position, the user has to work against the confront of the stretchable member (32) by stretching the member. This constraint is relaxed when the user again returns to the crouching position. In this way, the user exercises the muscles of the user's legs. The degree of exercise can 15 be controlled by adjusting the length of the invention of FIGs. 1 and 2. the stretchable member (32). <br><br>
FIGs. 5 and 6 illustrate a more detailed version of the invention of FIGs. I and 2. This embodiment is generally indicated at (40). The embodiment (40) includes a footrest (42) with a tear drop or annular configuration in section and with an aperture (44) near the thick end of the 20 footrest. A hollow rod (46) extends through the aperture (44). A strap (48) preferably made from a woven fabric material extends through the hollow rod (46). <br><br>
The strap (48) is extended through tri-glides (50) at the opposite ends of the strap and then through rings (52) near the ends of the strap. The strap may then be folded back upon itself at its opposite ends and is again extended through the tri-glides (50). In this way. the length of the 25 strap (48) between the rod (46) and each of the rings (50) may be adjusted by the user. The tri-glide (50) and the ring (52) are known in the art. The ring (52) may preferably have a D-shaped configuration. <br><br>
A stretchable member (54) corresponding to the stretchable member (18) in FIGs. 1 and 2 is wrapped around the D-shaped portion of each of the rings (52). The stretchable member (54) 30 may be provided with a hollow configuration and may be made from a suitable material such as a latex. The wrapped portion of the stretchable member (54) may be clamped to the rings (52) as by wire-tie generally indicated at (56). Each of the wire-ties (56) may include an open-ended loop (58) with the open ends of the loop extending through a clasp (60). A bellows (62) on the stretchable member (52) may be disposed within the wire-tie (56). <br><br>
35 The exercise unit provides for an adjustable tension in the stretchable member (54) in <br><br>
FIGs. 5 and 6 (and in the member (18) in FIGs. 1 and 2 and in the member (32) in FIGs. 3 and <br><br>

4) when the member is stretched. This results from the adjustments capable of being produced in the lengths of the strap (48) as by the inclusion of the tri-glides (50). <br><br>
5 FIG. 7 is a schematic perspective view of a second alternative embodiment, generally indicated at (63), of the invention. In this embodiment, a handle (64) is disposed on the stretchable member (54) to enhance the comfort to the user. A footrest (66) with an annular configuration in section is included in the embodiment of FIG. 7 to show that the footrest may have other than a tear drop configuration in section. The embodiment shown in FIG. 7 is 10 simplified relative to the embodiment shown in FIGs. 5 and 6 in that it eliminates the strap (48) and the tri-glide (50). <br><br>
FIG. 8 illustrates a third alternative embodiment of the present invention. Lower body stationing means comprising a footrest (72) includes two arms (74) and (76), the footrest (72) arid the arms (74) and (76) having an aperture for receiving a resistive structure (75) which, in 15 the embodiment illustrated in FIG. 8, comprises surgical tubing although it will be appreciated that other materials as resistive structures are possible such as latex. The footrest (72) includes a dial (78) in which the resistive structure is attached and increases or decreases the slack of the surgical tubing and therefore allows a user to adjust the resistance provided by the surgical tubing. <br><br>
20 The resistive structure (75) of the device shown in FIG. 8 further includes a user interface assembly (84) with an aperture for receiving the surgical tubing. The interface assembly (84) includes two flexible foam sheaths (80) and (82) coupled to an arcuate section (86) that interfaces with a user. The arcuate section (86) includes an internal reservoir for receiving a material such as water or sand through at least one of two handlebars (88) and (90), as will be 25 described below, to provide an adjustable resistance to upward movement of the interface assembly (84). <br><br>
At least one of the handlebars (88) or (90) includes a bore (92) for receiving a material such as water or sand, as previously described. Further resistance adjustment is provided by a plurality of removable weights (94), which may be attached to the handlebar by horizontally 30 sliding a U-shaped channel (96) on to the handlebar (88) or (90). The weights (94) may then be rotated and locked into place. Removal of the weights (94) is the converse of the process just described. <br><br>
The surgical tubing extends through the foam sheaths (80) and (82) and can either terminate and be rigidly secured to interface assembly (84) or can consist of a continuous loop j5 passing through the interface assembly. To use the apparatus, the footrest (70) is disposed on the ground such that the inclined portion of the footrest is disposed away from the user. This causes the footrest to be inclined and the ball and heel portion of the user's feet can be placed on <br><br>
-5- <br><br>
3T4403 <br><br>
29990/GSL/A490 <br><br>
the footrest when the user is lying with their back on the floor as shown in FIG. 1. The user grasps the two handlebars (88) and (90) and pulls the interface assembly (84) to be positioned 5 across the hip or abdominal area of the user, thereby stretching the resistive structure (75). The user then arches their back upwardly as shown in FIG. 2 while maintaining their feet firmly planted on the footrest. This causes the resistive structure (75) to become further stretched. As a result the user has to exercise their leg and gluteus muscles to stretch the resistive member. The user then returns their back to the position against the floor thereby relaxing the additional 10 tension in resistive structure (75). By moving the user's body between the position shown in FIGs. 1 and 2, the user is able to provide an efficient exercise of the user's leg and gluteus muscles. <br><br>
FIGs. 9 and 10 illustrate a fourth alternative and most preferred embodiment of the invention. In this embodiment, the exercise device (100) includes a base portion or footrest 15 (102) having curved arm portions (104) connected to the sides of the footrest by elbows (106). Elbows (106) are tubular L-shaped members having a lower leg (108) and an upper leg (110). Lower leg (108) extends into the footrest (102) through a circular opening (112) on the sides of the footrest. Upper leg (110) fits within tubular arm (104) on the lower portion of the arms. Elbows (106) allow arms (104) to rotate with respect to the footrest. End caps (116) are 20 positioned in the upper end of tubular arms (104). Preferably arms (104) are made of a lightweight metal such as aluminum, however other materials such as plastic can also be utilized. <br><br>
A handle (118) is positioned over arms (104) and is retained on the exercise device (100) by a resistance member (120). Resistance member (120) is an elongated stretchable material, such as surgical tubing or latex for example, or other suitable elastic material which continually 25 extends from a T-shaped coupling (122) through both arms and the footrest and terminating in a second T-shaped coupling (122). Couplings (122) are removably connected to the handle (118) through apertures (124) and (126) in the handle. Once inserted through openings (124) and (126) the couplings are rotated 90° and positioned within a recess on the top surface of the handle. The handle (118) also includes two hand recesses (128) having finger bars (130) for rigidly 30 grasping the handle. <br><br>
As shown in FIG. 11, the bottom of the base is equipped with two tensioning posts (132) and three tensioning hooks (134), (136) and (138). Tensioning posts (132) and tensioning hooks (134), (136) and (138) provide eight different tensioning adjustments for the resistance member (120). The first tensioning position (120a) is achieved by placing resistance member (120) 35 below tensioning posts (132). The second tensioning position (120b) is accomplished by placing the resistance member (i20) above tensioning posts (132). Tensioning position (120c) is accomplished by placing resistance member (120) under tensioning post (132) and over <br><br>
-6- <br><br>
'314 4 03 <br><br>
29990/GSL/A490 <br><br>
tensioning hook (134). Tensioning position (120d) is accomplished by placing resistance member (120) under tensioning posts (132) and over tensioning hook (136). Tensioning position 5 (120e) is accomplished by placing resistance member (120) under tensioning post (132) and over tensioning hook (138). Tensioning position (120f) is accomplished by placing resistance member (120) over tensioning hook (134). Tensioning position (120g) is accomplished by placing resistance member (120) over tensioning hook (136) and tensioning position (120h) is accomplished by placing resistance member (120) over tensioning hook (138). Because 10 resistance member (120) is an elastomeric material, the different tensioning positions provide different exercising resistances. As shown in FIGs. 10 and 11 the footrest includes viewing holes (140), (142) and (144) extending through the footrest which enables the user to see whether resistance member (120) is placed over tensioning hooks (134), (136) or (138). <br><br>
As shown best in FIGs. 9a and 9b, the footrest (102) provides three different angled 15 surfaces (146), (148) and (150) to provide five different feet positionings for working five different angles on the sets of muscle groups. In a first position the feet are placed on platform (148) to work the gluteus, some thigh and hip muscles. In a second position both feet are placed on platform (150), which has an angle greater than that of platform (148) to work the gluteus, top of the thighs and hip muscles. In a third position one foot is placed in the center of platform 20 (150) while the second foot is held in the air above the exercise apparatus for advanced gluteus muscle exercise. In a fourth position both heels are placed on platform (146) to work the gluteus, lower medius, thigh and hip muscles. In the fifth position the user's toes are placed on platform (146) to work the gluteus, hamstring, thigh and hip muscles. Any or all of the platforms (146), (148) and (150) can include traction surfaces (152) to prevent the user's feet from sliding on the 25 platforms during exercise. Preferably, the angle for platforms 146, 148, and 150 is approximately 22°, 9° and 17°, respectively, with respect to the ground surface. <br><br>
To utilize the apparatus the user lies with their back on the floor and places their feet on the footrest in one of the five positions discussed above. The user grasps the handle (118) by grips (130) and places the curved portion (153) of the handle across their lower abdomen. The 30 user then arches their back upwardly as shown in FIG. 2 while maintaining their feet firmly against the footrest. This causes resistance member (120) to be stretched and provides resistance along the handle. The user then returns their back to the position against the floor as shown in FIG. I thereby releasing the tension in the resistance member generated in arching their back. The exercise is continued by alternately moving between the positions shown in FIGs. 1 and 2 35 to provide an efficient exercise for the user's gluteus, thigh and hip muscles. <br><br>
Another feature of the exercise device shown in FIGs. 9 and 10 is that the handle and arms rotate around the footrest to lie flat for easy storage. Additionally the connection of the <br><br>
-7- <br><br>
29990/GSL/A490 <br><br>
314 403 <br><br>
resistance member (120) to the handle by T-connectors (122) allows the handle to be removed from the exercise device and used as a weight bar. In this configuration the handle can be designed to have compartments (154) for adding handle weights. In addition a foam pad can be placed on the inside surface of the curved portion of the handle for additional comfort to the user. <br><br>
The exercise unit disclosed above and shown in the drawings has additional important advantages. It is light in weight, simple in construction and portable. All of these advantages allow the user to carry the exercise unit in a suitcase with the user's clothes in a minimal amount of space when the user is traveling. In spite of its simple construction and light weight, the exercise unit provides for an efficient exercise of a number of different muscles in a user's body. Furthermore, the inclusion of the footrest provides comfort to the user when the user is exercising. <br><br>
Although this invention has been disclosed and illustrated with reference to particular embodiments, the principles involved are susceptible for use in numerous other embodiments which will be apparent to persons skilled in the art. The invention is, therefore, to be limited only as indicated by the scope of the appended claims. <br><br>
