Brief Patent Description - Full Patent Description - Patent Application Claims
[0001] The present invention relates to a device for strengthening and rehabilitating a person's muscles and is especially based on embodiments related to the principle of controlled exercise by having to balance/control instability during physical exertion. More precisely, the invention relates to a device as disclosed in the preamble of the attached independent claims. [0002] PCT Application Publ. No. WO00/68067 describes a pedal device for physical exercise, for example, a bicycle or exercise apparatus, wherein the device comprises a first pedal that is rotatably attached to a pedal shaft which at the free end thereof can be rigidly mounted to the crank arm, and wherein the first pedal has a pedal engagement face for use in the performance of conventional exercise, and wherein the device is made having a second pedal tiltably attached to the first pedal about an axis that extends transversely through a longitudinal axis of the pedal shaft. [0003] From what is previously known, exercise under controlled instability will have a positive health effect on a person's muscles, tendons and balance, both in the case of strength training and during rehabilitation after injury. It is important that the degree of movement of the devices which provide instability in an exercise apparatus can easily be adjusted and that this adjustment is stepless from a lockable position. This will spare a first-time user from experiencing a movement of the exercise apparatus for which he was unprepared. [0004] The earlier solutions for instability in exercise and sports equipment have limited areas of application. The pedals described earlier will typically be suitable for bicycles and stationary exercise bicycles, and are not suitable for use in fitness apparatus such as step machines and different exercise apparatus for combined leg and arm exercises. The object of the present invention is to solve the problem of how instability can be implemented in other exercise apparatus and exercise methods than those previously known. The characteristic features of the invention are set forth in the attached independent claims. Additional embodiments of the device are set forth in the associated dependent claims. Thus, the invention comprises solutions in connection with footrests that have a tilting function and adjustment thereof, and where the footrests can be adapted to suit different exercise apparatus. There will also be described apparatus equipped with footrests which in addition to a tilting function also have a sliding function, and that the exercise apparatus have different solutions for arm movements which include the use of poles and handles. The invention also comprises a number of solutions for manual and automatic adjustment of the tilting function of footrests and the length of the sliding function thereof. [0005] The application will describe the invention split into three main groups: [0006] footrests with a tilting function and adjustment of the degree of tilt and locking mechanisms therefor, and how these are adapted to and work in conjunction with different exercise apparatus; [0007] exercise apparatus which provide stride and step exercises with footrests that have both a sliding movement and a tilting movement; and [0008] exercise apparatus which provide a simulated walking and running motion with footrests that have both a sliding movement and a tilting movement. [0009] The invention will now be described in more detail with reference to the attached drawings: [0010] FIGS. 1a and 1b show footrests equipped with a device for tilting function. [0011] FIGS. 2a and 2c are sectional views through the adjusting mechanism for the tilting function of the footrests as indicated in FIG. 2b. [0012] FIGS. 3a and 3b show an exercise apparatus for stepping exercises in which bars have mounted thereon footrests for tilting function; [0013] FIGS. 4a and 4b show an exercise apparatus for circular leg exercises and arm movements, wherein bars have mounted thereon footrests for tilting function. [0014] FIG. 5 shows an exercise apparatus for stepping exercises wherein bars have a tilting function. [0015] FIG. 6 shows an exercise apparatus for circular leg exercises and arm movements, wherein bars have a tilting function. [0016] FIGS. 7a-7h show footrests with a further arrangement for adjusting the tilting function. [0017] FIGS. 8a-8c show an alternative arrangement for adjusting the tilting function of footrests. [0018] FIGS. 9a-9c show an exercise apparatus equipped with tiltable footrests, where exercises may consist of a stepping, sliding and tilting function for legs, and wherein the exercise apparatus has poles for arm movements. [0019] FIGS. 10a-10c show the exercise apparatus shown in FIG. 9, but with flexible poles. [0020] FIGS. 11a-11d show yet another variant of an exercise apparatus with tiltable footrests, and poles for arm movements. [0021] FIG. 12 shows detail XII of the exercise apparatus shown in FIG. 11. [0022] FIGS. 13a-13d show a variant of an exercise apparatus for the performance of circular leg exercises and arm movements, wherein footrests are in operation with adjustable spring bars. [0023] FIGS. 14a-14b show yet another variant of an exercise apparatus for the performance of circular leg exercises and arm movements, wherein the footrests have a sliding function relative to movable bars. [0024] FIGS. 15a-15b show a variant of an exercise apparatus for the performance of circular leg exercises and arm movements, wherein the footrests have a curved slide path. [0025] FIGS. 16a-16f outline different forms of slide paths and tracks for footrests. [0026] FIGS. 17a and 17b are perspective views from in front and from behind (from the underside) of the exercise apparatus shown in FIG. 15, and FIGS. 17c and 17d show details XVIIc and XVIId of links and adjusting mechanism. [0027] FIG. 18 is yet another figure of the exercise apparatus shown in FIGS. 15, 17a and 17b. Continue reading about Physical exercise apparatus and footrest platform for use with the apparatus...
