a reference numeral ( 10 ) represents an exercise apparatus of a present invention as shown in fig1 . the exercise apparatus ( 10 ) comprises a platform ( 20 ) on which a user performs all the exercises , a balance bar ( 50 ), a chair ( 70 ) and a plurality of accessories ( 80 ) for resistance training . in this embodiment , the platform ( 20 ) has a flat surface that is partially covered by a mat ( 30 ) preferably made out of rubber as it is known for its resistance to dampness and non - slippery characteristics . the platform ( 20 ) has a plurality of recessed eyelet cups ( 22 ) spaced evenly along both ends and center of the platform ( 20 ). a plurality of orifices ( 32 ) of the mat ( 30 ) are slightly larger in diameter than the recessed eyelet cups ( 22 ). the mat ( 30 ) fits directly over the surface of the platform ( 20 ) and the orifices ( 32 ) align with the recessed eyelet cups ( 22 ). referring to fig1 and 1 a : the recessed eyelet cups ( 22 ) contain a rotating eyelet system ( 40 ) that pivot 360 degrees and allows the user to pull a plurality of elastic cords ( 82 ) in various directions without changing user &# 39 ; s position on the platform ( 20 ). the rotating eyelet system ( 40 ) comprises an eyelet bolt ( 42 ), a plurality of washers ( 44 ) and a locking nut ( 46 ). the eyelet bolt ( 42 ) is mounted to the platform ( 20 ) below the surface level . thus , when the user steps onto the platform ( 20 ), the user will not step on the eyelet bolt ( 42 ) eliminating any chance of an accident . referring to fig1 a and 1 b : fig1 b specifically shows one of the preferred arrangements of the accessories ( 80 ). elastic cords ( 82 ) of variable length and strength based on the height and exercise level of the user are attached to the rotating eyelet system ( 40 ) by a clip ( 86 ) that is hooked to the eyelet bolt ( 42 ). only the center elastic cord ( 82 ) with an ankle strap ( 89 ), mainly for lower body exercises as shown on fig2 , uses a longer cord to provide the user full control of the exercise intensity , and uses a detachable swivel pulley ( 84 ) to protect the elastic cord ( 82 ) from increased friction caused by the consistent rubbing of metal and rubber and to allow the elastic cord ( 82 ) ease of movement . the detachable swivel pulley ( 84 ) is attached to the clip ( 86 ) and is hooked to the eyelet bolt ( 42 ). the two elastic cords ( 82 ) with a handle on each ( 88 ), are used mainly for upper body exercises and are hooked to the eyelet bolts ( 42 ) by the clip ( 86 ) in either ends of the platform ( 20 ) depending upon the type of exercises being performed . referring to fig2 a and 2 b : the exercise apparatus ( 10 ) provides a mechanism for the user to keep balance while performing lower body exercises with one leg . at one end of the platform ( 20 ) is a balance bar ( 50 ) held by a balance bar mounting system ( 60 ) which comprises of two balance bar mounts ( 62 ) either molded as one with the platform or constructed as separate pieces and mounted together . in this present invention , the balance bar mounting system ( 60 ) is molded as one with the platform ( 20 ). the balance bar ( 50 ) is held in place securely by a permanent pin ( 64 ) at the bottom of both the balance bar mounting systems ( 60 ) and a removable pin ( 66 ) located at the upper portion of the balance bar mounting system ( 60 ). the permanent pins ( 64 ) are engaged to the balance bar mounts ( 62 ) either in perpendicular or parallel position of the balance bar ( 50 ) to the platform ( 20 ). when the balance bar is in a perpendicular position to the platform ( 20 ), the removable pins ( 66 ) are engaged to the balance bar mounts ( 62 ). the removable pins ( 66 ) are disengaged from the balance bar mounts ( 62 ) when the balance bar ( 50 ) is in parallel position to the platform . referring to fig3 and 3 a : the exercise apparatus ( 10 ) also provides a chair ( 70 ) to perform resistance exercises and is geared to users who are physically challenged to stand while performing the exercises . in this embodiment , the chair ( 70 ) is shown as part of the platform ( 20 ); consists of a frame member ( 72 ) on each side of a seat ( 76 ) that supports the seat ( 76 ). the frame members ( 72 ) are used to assist the user for balance and leverage while performing some of the lower body exercises and when getting up from the chair . the two frame members ( 72 ) are held by a front and back brace ( 74 ) at a height that crosses the surface of the platform ( 20 ). the braces ( 74 ) rest lightly at the surface of the platform ( 20 ) and hold the platform ( 20 ) in a stable position utilizing the weight of the user sitting on the chair ( 70 ). referring to fig2 and 4 : in these embodiments , the exercise apparatus ( 10 ) can be used alternately without the chair ( 70 ), whereby the user can perform lower and upper body exercises by standing or sitting on the platform . accordingly , the reader will be able to determine the advantages and benefits of this present invention as it relates to its features and function . this exercise apparatus is designed in response to meet the needs of a specific group of population , namely the seniors and those individuals who are physically challenged to perform the normal movements of a physically - able person while exercising . although the description above explains many details , these should not be construed as limiting the scope of the invention but merely to illustrate some of the preferred embodiments . another embodiment of the present invention is for two users performing resistance exercises simultaneously . for example , one user is performing a lower body exercise with one - leg by the balance bar while the other user is performing an upper body exercise at the other end of the platform standing off the platform or on the floor . another embodiment is a larger , circular - shaped platform with more than one balance bar , more than one chair and a plurality of rotating eyelet systems that makes a work station for multiple users . as a result , the extent of the present invention should be determined by the claims and their legal equivalent .
a new , safely - designed and portable exercise apparatus comprising of a platform on which a user performs a variety of resistance and cardiovascular exercises ; a balance bar to assist with balance as a user performs lower body exercises with elastic cords for resistance ; for stepping up and down the platform to maintain balance for coordination and for cardiovascular benefit ; a chair to assist a physically challenged user to perform upper and lower body resistance exercises .
