The present invention relates to the field of exercise equipment, and, in particular, to a multiple-person elliptical trainer.
BACKGROUND OF THE INVENTIONMany people strive to maintain, or even increase, their fitness level by regularly exercising. Regular exercise can improve fitness in a variety of ways, including improving cardiovascular health, strength, and balance and flexibility. Some people buy gym memberships so they can exercise at a gym. Many gyms contain exercise equipment with smooth motions and consistent resistances that can be used to improve fitness in various muscle groups. However, a gym membership can be expensive, and gyms can be crowded during popular workout times, making workouts slow and time-consuming. Blaring music, pushy trainers, and supplement salespeople can also be annoying to some users. Additionally, competitive and intense users can be intimidating to beginners and casual users. Gyms may be inconveniently located, may have inadequate parking, or may maintain hours of operation that conflict with a busy work, or school, schedule.
Some people, instead, opt to exercise at home using home exercise equipment, which can provide a convenient, low-cost, small-scale alternative to gyms. However, low-cost, small-scale home exercise equipment can be difficult and uncomfortable to use and often does not provide a user with the same level of smooth motions and consistent resistances that a user may find with larger-scale commercial exercise equipment found in gyms. Additionally, low-cost, small-scale home exercise equipment may not efficiently exercise various muscle groups, and may fail to exercise certain muscle groups altogether. People exercising at home can also be distracted by many different types of commonly-occurring events, including telephones ringing, pets and/or roommates needing attention, and people knocking on the door.
Increasing cardiovascular fitness is a desire of many users. Cardiovascular fitness can be improved by a number of different ways, including running, walking, bicycling, swimming, cross-country skiing, and using cardiovascular exercise equipment. However, many people live, work, or attend classes in areas where certain outdoor cardiovascular exercises are difficult or impossible. Additionally, due to price and electronic-supply constraints, cardiovascular exercise equipment, such as treadmills, stair climbers, and other electronic-based exercise equipment are often confined to high-priced gyms. Home cardiovascular exercise equipment, such as exercise bikes, can be bulky, uncomfortable, poorly constructed, and clunky. Additionally, many of the cardiovascular exercise equipment found in gyms and at home can only accommodate a single user at a time. People who are interested in staying fit have, therefore, recognized a need for a way to promote cardiovascular fitness without relying on visiting a gym, purchasing low-cost, small-scale home cardiovascular equipment, or engaging in outside activities that need specific geographical and/or climactic conditions.
SUMMARY OF THE INVENTIONVarious embodiments of the present invention are directed to an indoor/outdoor, multiple-person elliptical trainer for improving cardiovascular fitness. In one embodiment of the present invention, the multiple-person elliptical trainer includes two training stations mounted to a support frame. Each training station includes a pair of roughly parallel tracks, each track pivotally attached to a swing arm at a front end and a crank arm at a rear end. The crank arms, in turn, are interconnected to each other via a rotatable axle attached to the support frame. Each track further includes a foot pedal and each swing arm includes a swing-arm handle. In one embodiment of the present invention, a user can place a foot on each of the foot pedals, grasp the swing-arm handles, and rotate the crank arms by rhythmically pushing and pulling the swing-arm handles while using the foot pedals to simulate a walking or running gait.
Various embodiments of the present invention are directed to an indoor/outdoor, multiple-person elliptical trainer for improving cardiovascular fitness.
Each side base bar 112 and 114 includes a relatively flat inner portion 116, an upwardly-bending rear portion 118, and an elongated, upwardly-bending front portion 120. The inner portions 116 of the side base bars 112 and 114 interconnect the front base bar 108 and the rear base bar 110. The rear portions 118 of the side base bars 112 and 114 bend upwards to roughly a 45° angle and each contain a roughly-horizontal, open-tube rear terminus 122. A rotatable axle 124 inside each of the rear termini 122 interconnects a pair of crank arms, such as first crank arm 126 and second crank arm 128 on the training station 102. The front portions 120 of the side base bars 112 and 114 bend upward to a roughly vertical orientation and each contain a roughly-horizontal, open-tube front terminus 130. In alternate embodiments of the present invention, instead of utilizing single side base bars with each side base bar having a flat inner portion, an upwardly-bending front portion, and an upwardly-bending rear portion, the support frame utilizes multiple bars that include one or more roughly flat base bars, one or more interconnected upwardly-directed front base bars, and one or more interconnected upwardly-directed rear base bars, as discussed below with reference to
Similarly, the second track 204 is pivotally attached to the second crank arm 128 at a second rear end 218 and pivotally attached to a second swing arm 220 at a second front end 222. The second swing arm 220 is pivotally attached to the front terminus 130 of the support frame 106 at a second front-terminus pivot 224. Above the second front-terminus pivot 224, the second swing arm 220 forms a second swing-arm handle 226 with a second swing-arm grip 228 at the distal end. In one embodiment of the present invention, the second front-terminus pivot 224 includes a horizontal bar (not shown in
In
The user 800 can vary the amount of effort used to rotate the first crank arm 126 and the second crank arm 128 by varying the amount of force applied by each of his hands 806 and 808 and feet 802 and 804. The user 800 can also vary the relative amount of pressure applied by each hand 806 and 808 and foot 802 and 804 in relation to the other hand 806 and 808 and foot 802 and 804. For example, the user 800 can apply a relatively higher amount of force with his left hand 808 and left foot 804 than with to his right hand 806 and right foot 802. Alternately, the user 800 can use different combinations of one or more hands 806 and 808 and/or one or more feet 802 and 804 to apply the majority, or all of, the force needed to rotate the first crank arm 126 and the second crank arm 128.
The directions of the movements of the first swing arm grip 216 and the second swing arm grip 228 are alternating back-and-forth motions in both of the directions indicated by the directional arrow 604, whereas the movements of the first crank arm 126 and the second crank arm 128 are in either a clockwise or counterclockwise motion. The user 800 can control the direction of the first crank arm 126 and the second crank arm 128 to be in either of the directions indicated by the directional arrow 602 by controlling the application of force applied to the right foot pedal 302 and the left foot pedal 304. However, the motions of the first swing arm grip 216 and the second swing arm grip 228 are back-and-forth regardless of the positioning and directionality of the first crank arm 126 and the second crank arm 128.
The support frame 106 for the elliptical trainer 100, described above with reference to
L-shaped bolts, such as L-shaped bolt 1002, have been passed through the mounting apertures (314 in
In alternate embodiments of the present invention, the support frame can accommodate additional training stations, and additional users can simultaneously exercise using the elliptical trainer.
A multiple-person elliptical trainer can include a number of training stations in alternate orientations.
A walking simulator can be used in combination with other pieces of cardiovascular exercise equipment.
The elliptical trainers described above can be placed indoors and outdoors at a number of different locations, including private homes, yards, elementary schools, middle schools, high schools, colleges, universities, hotels, motels, resorts, cruise ships, commercial-building courtyards, parks, trails, recreation centers, community centers, residential and lifestyle communities, hospital grounds, out-patient clinics, golf courses, and other indoor and outdoor locations. The anchoring mechanisms described above, with reference to
Additional modifications within the spirit of the invention will be apparent to those skilled in the art. For example, adjustable resistances can be incorporated into an elliptical trainer by the manufacturer, distributor, and/or a user. Additional flat bars can be attached to the support frame of an elliptical trainer for anchoring the elliptical trainer to the ground. Removable and non-removable devices can be attached to the support frame, such as water-bottle holders, book and magazine holders, towel holders, and radio/MP3-player holders. The foot pedals can be angled to change the gait used by a user. Angling the foot pedals can be accomplished in a number of different ways, such as bending and/or curving the tracks on which the toe plates are located. Similarly, the swing-arm handles can be bent and/or curved to change the positioning of a user's hands. Changing hand positions can change a user's comfort level and can also change the muscles used and the amount of force that a user is able to apply to the swing-arm handles. Various materials can be used to fabricate exercise apparatuses, such as metals and composite materials.
