FIELD OF INVENTION
The present invention relates to an exercise apparatus and more specifically to a multi-attachment exercise apparatus with interchangeable and adjustable parts for multi-directional training of the user.
BACKGROUND OF THE INVENTION
The human body moves in multi-planar directions and incorporates a multitude of muscles all working in combination simultaneously in almost all aspects of life. Strength, mobility, flexibility, cardio-conditioning, balance, muscle awareness, and coordination are all important during daily life, particularly in the area of sports conditioning and movement but also in normal human activities found in everyday life, such as loading groceries into a car, walking the dog on a slippery sidewalk in the snow, raking leaves, etc. Existing exercise devices do not allow the user to train all these aspects simultaneously even though we live in a world that requires such skills.
Existing swing training fitness devices are designed to simulate the walking patterns of a user. They are limited in their functionality and are usually fixed in a single use design. They swing forward and backward in an arced path, with the user standing on two pedals attached to two solid bars with a pivot point at about waist height and usually with the other end of each bar above the pivot point for the user to hold onto. As the user swings each leg alternatively forward and backward, the user's legs simulate a walking pattern. Such a device can be used for a cardio exercise, but it provides very limited strength to the user. Exercises particularly in the mid-section, hips, legs, ankles, and the connective tissues enjoining all of muscles in these areas are not provided by the existing fitness devices. Further, the training and coordination of the lower body in conjunction with the upper body is not served by these products.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION
The preferred embodiments of the present invention will now be described with reference to FIGS. 1-21 of the drawings. Identical elements in the various figures are designated with the same reference numerals.
Embodiments of the present invention provide an exercise apparatus for multi-directional and multi-planar training of the body of the user. In the description of the present invention, numerous specific details are provided, such as examples of components and/or mechanisms, to provide a thorough understanding of the various embodiments of the present invention. One skilled in the relevant art will recognize, however, that an embodiment of the present invention can be practiced without one or more of the specific details, or with other apparatus, systems, assemblies, methods, components, materials, parts, and/or the like. In other instances, well-known structures, materials, or operations are not specifically shown or described in detail to avoid obscuring aspects of embodiments of the present invention.
FIG. 1a illustrates an exercise apparatus 100 along with its various parts. The exercise apparatus 100 consists of a main frame 10 which supports foot platforms 20 substantially in parallel by means of hanging members or elements 30, such as chains, cables, ropes, bands, or rods. The main frame 10 comprises a C-shaped holding bar 12 and support bars 14. The holding bar 12 of the main frame 10 is attached to the support bars 14. The user steps on the foot platforms 20 and holds the holding bar 12 when commencing a workout. The support bars 14 are adapted to be attached to a mounting support, such as a wall or floor, with the aid of mounting means. The mounting support can be a wall, or a separate stand, or any supporting frame such as a SUPERCELLTM exercise system available commercially from Vortex Fitness Equipment of Wilmington, Del.
The hanging elements 30 used to attach the foot platforms 20 to the main frame 10 are adapted for moving in multiple directions, with two degrees of freedom in an X-Y plane, thereby allowing the user to train his/her body in multi-directional patterns for better strength, mobility, flexibility, cardio-conditioning, balance, muscle awareness and coordination. Multiple connection points 40 on the holding bar 12 permit adjustment of the distance between the foot platforms 20, and also permit the foot platforms 20 to be suspended at a slight angle (away from strictly parallel) to accommodate “pigeon toed” users and the like. Further, additional connection points 40 could be positioned vertically to raise or lower hanging elements 30 and/or to raise or lower ends of platforms 20, whereby the platforms 20 are raised, lowered, and/or tilted. Optionally, holding bar 12 can be rotatably held at the ends of support bars 14 with a mechanical arrangement, such as a pop pin arrangement, so that holding bar 12 can be tilted up or down and locked in position, as shown in FIG. 14.
The holding bar 12 has swivel snap hooks or clips 42 which are further attached to a carabiner 44 to lock the links of one end of the hanging elements 30. A snap hook or the carabiner 44 can be used to adjust the length of each respective hanging element 30. On the other end of the hanging elements 30, bungee cords or similar elastic members 50 can be attached to connect the hanging elements 30 to foot platforms 20. This gives the platform an additional degree of freedom of movement, in the vertical or “Z” direction, enabling the user to bounce up and down. Alternatively, non-elastic members 50 can be used to connect the foot platforms 20 to the hanging elements 30.
In another embodiment only the carabiner 44 can be used to lock the links of the hanging elements 30. The present invention contemplates the use of swivel snap hooks 42, whereas other types of hooks or connecting means can be used without altering the scope of the invention.
In an optional embodiment of the invention, to limit the relative spacing of platforms 20, at least one member 16, preferably one or two, extends between platforms 20. Each member 16 is attached to a platform 20 at an attachment point 18. A member 16 comprises elastic, for example, a spring or band, or non-elastic material of a length of from about 15 to about 45 cm.
In another embodiment the hanging elements 30 are slidably attached to the main frame 10 as illustrated in FIG. 1b. Ring members 46 can be used to attach the hanging elements 30 to the holding bar 12, thereby allowing the user to adjust the points of attachment of the hanging elements 30 to the most comfortable position.
In still another embodiment, the holding bar 12 is provided with various connecting elements 48 to allow the user to attach the hanging elements 30 at specific points on the holding bar 12 as illustrated in FIG. 1c. 
In still another embodiment, provisions 70 are made on the support bars 14 of the main frame 10 for accommodating crossbars 60 or similar structures as illustrated in FIG. 1d. The crossbars are affixed to the support bars by means of pop pins 64, or the like. Various accessories can be attached to the crossbars 60 to facilitate several types of workouts.
One such accessory can be a detachable device for upper body training as illustrated in FIG. 2a. This accessory allows the user to train the upper body either in unison or in isolation to the lower body. The attachment includes two horizontal handles mounted on an upright bar 80, the bottom end of which is pivotally mounted on a crossbar 60 fitted between the support bars 14 of the main frame 10. The bar 80 is lockable in a fixed upright position, or in any one of several different tilted positions, but when unlocked it can tilt freely in any direction. Bar 80 may end in a ball in socket 72 so that bar 80 can be rotated or pivoted in all directions.
With the attachment shown in FIG. 2a, an elastic member 90 is used to provide resistance to tilting motion of the bar 80. One way of attaching an elastic member 90 is to connect it between the top end of the handle 80 and a post 110 attached to a second crossbar 62. Another way is to attach multiple elastic members 94 to the bottom of the bar 80 as shown in FIG. 2b. In this embodiment, one end of the elastic members is attached to the bottom end of the bar 80 and while the other end is attached at various points to the main frame 10. The bar 80, which is pivoted on the crossbar 60 and may end in a ball in socket 72, can be moved in any direction away from the vertical or can be rotated or twisted using the handles 66a and 66b; however, it is continually biased toward the upright position by the elastic members 94. As in the case of the embodiment of FIG. 2a, the bar 80 in the embodiment of FIG. 2b can be locked in the upright position, or in one of a number of different non-upright positions as selected by the user, to prevent tilting movement.
Optionally, bar 80 and socket 72 may have means to adjust pressure on the ball.
Another such upper body training accessory can be a detachable exercise bicycle device 120 with an adjustable resistance to facilitate an upper body workout of the user as illustrated in FIG. 3. The hand operated bicycle device 120 is mounted on a post 130 which is attached to the crossbar 60. When coupled to a device for measuring the energy expended by the user, this type of accessory is sometimes referred to as an “ergometer.”
To provide information about the use of the exercise apparatus, a number of electronic sensors may be disposed at various points on the apparatus. For example, as shown in FIG. 2b, metal sensors 68a and 68b may be mounted on the handles 66a and 66b, respectively, to sense the heart rate of the user. A motion sensor 24 may be mounted on the movable bar 80 to sense the position, speed and/or acceleration of the bar.
On or more such motion sensors 122a and 122b may also be fitted to the hand-operated bicycle device, as shown in FIG. 3.
In still another embodiment of the invention, the foot platforms 20 are fitted with various accessories for ankle training in multiple directions. The accessory can be a pivotal circular plate 140 as shown in FIG. 4a. The accessory can also be a half ball 146 made up of a material such as rubber as shown in FIG. 4b. A rotatable disc 136 can also be used as an accessory for the foot platforms 20 for developing rotational strength of the ankle of user as shown in FIG. 4c. These accessories may be both attachable and detachable, so that the user can apply them to the foot platforms 20 whenever an ankle exercise is required.
In still another embodiment of the invention, a foot platform 26 is pivoted centrally as shown in FIG. 4d so that the platform can rock up and down. This extra degree of freedom, in addition to the basic two degrees of freedom afforded the foot platform by the hanging elements 30, enables the user to perform ankle training.
In still another embodiment of the invention, the exercise apparatus 100 is mounted on a stand 200 with crossbars 230 using a ladder hook-on assembly 150 thereby making it a stand-alone product as shown in FIG. 5a. The ladder hook-on assembly 150 is attached to the support bars 14 of the main frame 10 of the exercise apparatus 100 as shown in FIG. 5b. Ladder hook-on assembly 150 helps in adjusting the height and position of the exercise apparatus 100 and can be attached or detached from the stand 200 as well as from the exercise apparatus 100 with ease.
Motion sensors 22a and 22b can be provided on the foot platforms to sense the motion imparted by the user. These and the other sensors that may be provided on the exercise apparatus are connected to an electronic system (not shown) for processing and signals and providing an image display in response to these signals.
In FIG. 5b each platform 20 has a vibrator 52 attached thereto. The vibrators 52 communicate with a vibrator control 54, wirelessly or through wiring 56. Vibrators 52 may have batteries or may be connected to a power source (not shown).
An exploded view of the stand 200 is illustrated in FIG. 5c. The stand 200 has vertical members 210 which are attached to each other by crossbar 230 forming a ladder-like frame structure. The vertical members 210 are attached to horizontal members 220 by well known means, such as gusset plates 250. The horizontal members 220 are provided with leveling feet 260 which can be adjusted to raise, lower, or tilt stand 200 as desired. The side view of the stand 200 as shown in FIG. 5d depicts the connection between the vertical members 210 and horizontal members 220 by the gusset plate 250 and the arrangement of the leveling feet 260 on the horizontal members 220. FIG. 5e depicts the use of hexagonal lock nuts 270 on the horizontal members 220 in attaching the feet 260.
The exercise apparatus 100 can optionally be mounted with ladder hook-on assembly 150 or another locking or mounting assembly on a wall or any supporting structure, such as a girder, a crossbeam, or another, larger exercise apparatus.
In still another embodiment of the invention, the exercise apparatus 100 can be adapted to be used by a physically challenged person. A person having a disabled leg can rest the disabled leg on a foot rest mounted on the apparatus and perform the exercise with the other leg. Also, the exercise apparatus can be designed to be used by a person in a wheelchair. The user can perform upper body exercise by attaching an add-on to the main frame 10. A locking device can be provided to lock the wheelchair of the user to avoid movement of the wheelchair while the user is performing the exercise. Various other alterations in the design of the equipment can be made to help a physically challenged person in performing several types of exercises without changing the scope of the invention.
In still another embodiment of the invention, one or more sensors can be disposed within the exercise apparatus 100. The sensors can be integrated with a screen display for interactive use. The sensors can also be used to sense the heartbeat rate or other body conditions of the user in order to display these conditions on a screen and to notify the user about his/her physical health status. Various other types of sensors, such as pulse sensor, heart rate sensor, motion sensor and/or the like can also be used for information transfer between the exercise device and the user.
In still another embodiment of the invention, the exercise apparatus 100 can be equipped with electricity generating means to convert the physical energy of the user into electrical energy. Generated electrical energy can be used to power the exercise apparatus 100, lighting of the exercise room, or the like.
While support bar 14 is preferably perpendicular to member 308 of ladder hook-up assembly 150, bar 14 can be rotatably positioned at an angle other than 90° by use of a plate 628 and pop pins 630, as shown in FIG. 14.
In another embodiment of the invention shown in FIGS. 6a to 6d, support members 290 are attached to a handle bar 292 and an attachment member 294, which attachment member 294 can be attached to a wall mount or a stand, such as stand 300. A platform support 302 is attached to each support member 290 at a pivot point 304.
Each platform support 302 comprises a longitudinally extending member or hanging member 306 and a foot platform 310. Hanging member 306 may comprise two or more adjustable elements. In FIG. 6a, upper section 314 and lower section 318 can be fixed in length or preferably they can be adjusted against each other to vary the height of a platform 310. Platform 310 is attached to the lower portion 318 of hanging member 306, and elastic bands 320 extend from hanging member 306 to the ends of platform 310.
Elastic bands 320 are attached to lower portion 318. Each foot platform 310 can pivot around pivot point 322.
Variations of the portion of the invention shown in FIG. 6a are shown in FIGS. 6b and 6c. In FIG. 6b, hanging member 306 has holes 326 in lower section 318 to accommodate repositioning foot platform 322. Similarly, the lateral surfaces of hanging member 306 have hooks or similar means 308 to receive an end of an elastic band 320 as a foot platform 322 is repositioned.
In FIG. 6c, a foot platform 310 is pivotably positioned at the end of lower section 318, with elastic bands 320 fixedly attached to section 318. Upper section 316 and lower section 318 are adjustably joined at point 330, where, for example, one or more bolts or pop pins 332 engage reciprocal openings 334 in sections 314 and 318.
The aspect of the invention reflected in FIG. 6d comprises a hanging member 306 with a spring loaded lever 340, to secure the longitudinal relationship between sections 314 and 318.
