BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to exercise equipment, and more particularly to a removable recumbent seat attachment for use with an existing stationary exercise cycle.

[0004] 2. Description of the Prior Art

[0005] Numerous stationary exercise devices are known in the art, including stationary bicycles, treadmills, rowing machines, and stair stepping devices to name a few. Stationary cycle devices are ordinarily outfitted with a single adjustable seat that may be adjustably positioned such that when the user is seated therein, the user's arms reach the handle(s) and the user's feet reach the pedals. Some stationary cycles provide a single upright seat, while others provide a single recumbent seat. Unfortunately, for those cycles that provide the single upright seat, it is not possible or practical to move or adjust the seat into a recumbent position for exercising the legs for long periods of time. The availability of only the upright seat adds more strain and fatigue to the user's lower back during longer workouts, which may lead the user to shorten the workout thereby reducing the effectiveness of the exercise machine. It is therefore desirable to provide a recumbent seat alternative for existing exercise cycles having only an upright seat.

SUMMARY OF THE INVENTION

[0006] The present invention addresses this problem by providing an adjustable recumbent add-on seat that may be used in conjunction with a wide variety of upright stationary exercise cycles for use in exercising the legs over long periods of time. Most ordinary exercise cycles include a base that is deployed on the floor, the base supporting a chassis, seat and one or two upright handles. The chassis ordinarily contains the pedal mechanism for the cycle. The seat support and handle(s) may be attached either to or through the chassis, or directly to the base.

[0007] The present invention provides a independent and free-standing adjustable base that supports a recumbent seat that is adjustably mounted on a generally vertical standard. The base of the present invention is designed to be deployed directly behind and adjacent to an existing exercise cycle. The standard supporting the recumbent seat may be adjusted laterally relative to its base to bring the seat support as close to the exercise cycle as desired. The seat may also be adjusted vertically on the standard to properly position the seat. Both adjustments are made in order to allow the user's feet to reach the pedals of the exercise cycle while seated in the recumbent seat. This allows the user to lean back and exercise the legs. The base of the recumbent seat is preferably detachably engaged with the base supporting the cycle to avoid separation during use. In one embodiment, the recumbent seat may include a pair of gripping handles which are attached thereto. In another embodiment, the base for the free-standing recumbent seat is provided with frictional floor members to prevent movement of the base during use.

[0008] The present invention also provides a vertically oriented exercise device for working out both arms and legs simultaneously or independently. This device may be used with or without the recumbent seat. In the exercise device, a stationary base (main base) is provided having an adjustable vertical standard attached thereto. A rotatable pedal operated load wheel is provided near the bottom of the standard. Friction drag on the load wheel may be adjusted to make it easier or more difficult to rotate using the arms and/or the legs. A cushioned seat is provided for attachment to the standard at an adjustably convenient central location thereby allowing the user to comfortably sit thereon while also reaching the pedals attached to the load wheel. A pair of movable hand grips are provided near the upper end of the standard to be held by the user during exercise. Each of the hand grips is attached to a slidable vertical member, and each such member is attached through a set of pivoting linkages to the pedals on the load wheel. These linkages allow force applied to the hand grips to directly turn the load wheel. Thus, the legs independently, the arms independently, or both the arms and legs together may be used to turn the load wheel. As a result, without exiting or changing anything on the exerciser, the user may shift the emphasis of force back and forth from the arms to the legs during a given workout. The user may rest the legs while operating the device using only the arms, and vice versa.

[0009] In an alternative embodiment of the exercise device, it may independently or additionally include a second adjustable upright standard adjustably attached to the main base. This standard supports a pair of vertically oriented handle members which are pivotally attached at the top of the standard. A hand grip is provided at the top of each handle member. The bottom of each handle member is hingedly attached to one end of a motion transmission member. The opposite end of each motion transmission member is attached at the pivot of one of the load wheel pedals. Thus, as the pedals move around the wheel, oscillating motion is imparted to each transmission member, and thus to each handle member. Alternatively, as the handle members are moved back and forth, the load wheel can be turned. This allows the user to shift the emphasis of force from the arms to the legs without exiting the exercise device.

[0010] In another alternative embodiment of the exercise device, it may independently or additionally include a second adjustable upright standard adjustably attached to the main base for supporting a stationary handle.

[0011] In the preferred embodiment, the adjustable recumbent seat is provided with the exercise device of the present invention on either (1) a removable independent free-standing base, or (2) on the same main base as the exercise device itself. This allows the exercise device to be used as a recumbent exercise machine for exercising the legs. The recumbent seat also preferably includes a pair of gripping handles which are attached thereto.

[0012] It is therefore a primary object of the present invention to provide an adjustable recumbent seat and support device that may be used in conjunction with an existing stationary exercise cycle to allow the user the option of exercising the legs for long periods of time from a recumbent position.

[0013] It is a further important object of the present invention to provide a simple and inexpensive free-standing apparatus for use with an existing stationary exercise cycle of a type having an upright seat that allows the user to exercise the legs from a recumbent position without requiring the purchase of an entirely new exercise cycle.

[0014] It is a further important object of the present invention to provide a stationary exercise machine having a pair of vertical standards, the first standard supporting a pedal operated load wheel, an adjustable seat, and a pair of slidable hand grips which are connected to the load wheel through a series of linkages thereby allowing the load wheel to be rotated by sliding the hand grips, and the second standard supporting an adjustable recumbent seat with optional handles attached thereto.

[0015] It is a further object of the present invention to provide a pair of stationary bases, the first base supporting a multiple-use exercise machine having two vertical standards, one standard supporting a load wheel, an adjustable seat, and a pair of slidable vertical members with handles and linkages to the load wheel for exercising the arms and legs, and the other standard supporting a set of oscillating handle members connected to the load wheel through a series of linkages for exercising the arms and legs; the second base supporting a third standard supporting an adjustable recumbent seat with optional handles attached thereto.

[0016] It is a further object of the present invention to provide a pair of stationary bases, the first base supporting a multiple-use exercise machine having two vertical standards, one standard supporting a load wheel, an adjustable seat, and a pair of slidable vertical members with handles and linkages to the load wheel for exercising the arms and legs, and the other standard supporting a set of stationary handle members; the second base supporting a third standard supporting an adjustable recumbent seat with optional handles attached thereto.

[0017] It is a further object of the present invention to provide a single stationary base for supporting a multiple-use exercise machine having three vertical standards, one standard supporting a load wheel, an adjustable seat, and a pair of slidable vertical members with handles and linkages to the load wheel for exercising the arms and legs; another standard supporting a set of oscillating handle members connected to the load wheel through a series of linkages for exercising the arms and legs; and a third standard supporting an adjustable recumbent seat with optional handles attached thereto.

[0018] It is a further object of the present invention to provide a single stationary base for supporting a multiple-use exercise machine having three vertical standards, one standard supporting a load wheel, an adjustable seat, and a pair of slidable vertical members with handles and linkages to the load wheel for exercising the arms and legs; another standard supporting a set of stationary handle members; and the third standard supporting an adjustable recumbent seat with optional handles attached thereto.

[0019] It is another object of the present invention to provide a stationary exercise machine which allows the user to operate the load wheel using the legs independently, the anms independently, or both the anms and legs together.

[0020] It is a further object of the present invention to provide a stationary exercise machine which allows the user to shift the emphasis of force back and forth from the arms to the legs during a given workout without exiting the machine or changing anything on it.

[0021] It is a further object of the present invention to provide a stationary exercise machine which allows the user to rest the legs while operating the device using only the arms.

DETAILED DESCRIPTION OF THE DRAWINGS

[0038] Referring to the drawings wherein like reference characters designate like or corresponding parts throughout the several views, and referring particularly to FIG. 7, it is seen that the improvement of the present invention is a free-standing stationary base 61 having front and back leg members 62 and 63. An upright standard 64 is attached to base 61. Standard 64 may extend upward vertically, or may extend upward at an angle such that recumbent seat 45 leans slightly back. Base 61 supporting seat 45 is adjustable with respect to front leg 63 in order to allow the position of standard 64 and associated seat 45 to be adjusted relative to the front of the assembly. The adjusted position may then be fixed using an appropriate means such as knob 66 inserted into the corresponding opening on base 61. Similarly, the vertical position of seat 45 may be adjusted on standard 64 using an appropriate means such as knob 67 inserted into the corresponding opening on standard 64. A single handle or a pair of handles 47 may optionally be provided on seat 45 for the user to grip with the hands while exercising. Seat 45 may be of any suitable form, such as the single unit seat shown in FIG. 2D, or a multi-part seat shown in FIGS. 6 and 7.

[0039] Turning to FIG. 6, it is seen that the free-standing base 61 supporting recumbent seat 45 is designed for placement directly behind the base 11 of a typical exercise device. Straps, bolts, clamps or other suitable means 65 may be used to removably attach the front leg 63 of free-standing base 61 to the back leg 9 (or other similar support structure) of the exercise device in order to prevent base 61 from separating from base 11 of the exercise device during use. Alternatively or in addition to the removable attachment means 65, a plurality of frictional members 68 may be provided to prevent slippage of legs 62 and 63 on the support surface where deployed. Frictional members 68 may be made of any suitable material such as rubber or plastic, and may be provided with an appropriate pattern for maximizing frictional contact with the underlying surface.

[0040] FIGS. 2A-2C illustrate different embodiments of the combination of the recumbent seat with different versions of an exercise device on a single base. It is to be appreciated that the recumbent seat 45 may be provided on the same base 11 with any one of a host of different exercise machines, the illustrations simply providing some examples of such machines.

[0041] FIGS. 2D and 6 are illustrations of examples of the free standing version of base 61 with legs 62 and 63 supporting the recumbent seat 45 deployed with different exercise devices. It is likewise to be appreciated that the adjustable recumbent seat 45 may be provided on the free-standing base 61 and used with any one of a host of different exercise devices, the illustrations simply providing some examples of such devices.

[0042] Referring to FIGS. 1-3 it is seen that the exercise device of the present invention includes a support base 11 having a vertical standard 12 attached thereto. The load wheel 14 is rotatably attached to standard 12 near the bottom at pivot 13. An adjustable tension strap 15 is wrapped around wheel 14 and may be tightened or loosened to adjust friction drag on the load wheel using adjustment screw 16 on base 11 A pair of pedals 17 (and 17a) are pivotally attached to the center of wheel 14

[0043] Strap 15 is attached around the outer edge of wheel 14 and is mounted at either end on base 11. One end of strap 15 is adjustable at 16 so as to allow different tension (friction) to be imparted to the wheel. The outer edge of wheel 14 is slidably (rotatably) attached to the wheel itself so that wheel 14 rotates inside edge 19.

[0044] A seat 20 is provided which may be adjustably attached to standard 12 at almost any location using support bar 21.

[0045] A pair of hand grips 41 (and 41a) are provided on the device. Grips 41 and 41a are attached, respectively, to the upper portions of slidable vertical members 33 and 33a. The positions of the hand grips may be adjusted to fit the user. At least two enclosures or housings 31 are provided along the length of standard 12 which guide, support and retain slidable members 33 and 33a. The lower ends of slidable members 33 and 33a are pivotally attached, respectively, to the upper ends of linking members 35 and 35a at pivots 34 and 34a. The lower ends of linking members 35 and 35a are pivotally attached, respectively, to the central pivots of pedals 17 and 17a (see FIGS. 2 and 3). This construction allows vertical force (whether up or down) applied to the hand grips to be transmitted through members 33 through linkages 34 and 35 to pedals 17 in order to rotate wheel 14.

[0046] Detail of housing 31 is shown in FIG. 4. The housing 31 is made of two halves that are bolted together to allow firm support to members 33 while also making access possible for lubrication and repair A flange 36 is provided at the top of each of members 35 to provide clearance between member 35 and wheel 14 as shown in FIGS. 1 and 5.

[0047] In the alternative embodiments shown in FIGS. 2A, 2B and 2C, it is seen that an adjustable seat 45 is provided on base 11. Seat 45 may be laterally and vertically adjusted by the user for optimum distance from pedals 17. Optional grip handles 47 may be provided on seat 45 for the user to hold him/herself in position while pedaling the load wheel in a recumbent position. Seat 45, handles 47 and load wheel 14 with pedals 17 may be independently or additionally provided in the exercise device.

[0048] FIGS. 2A, 2B and 2C also illustrate another alternative or additional aspect of the exercise device utilizing a second adjustable vertical standard 51 which supports either a single handle or hand grip 56 (FIG. 2C) or a pair of elongated oscillating handle members 54 (FIG. 2B). Standard 51 may be adjusted both vertically and horizontally to place the handle 56 or handle members 54 in an optimum position for the user. As shown in FIG. 2B, members 54 are pivotally attached to standard 51 at pivot 53. Hand grips or handles 55 are provided at the tops of members 54. A pair of transmission members 58 are provided between the lower ends of members 54 and pedals 17. This construction allows force applied to the pedals to move the handle members 54 back and forth, or force applied to the handle members 54 to rotate the load wheel 14.

[0049] The second vertical standard 51 supporting oscillating members 54 allows the user to exercise the arms. Thus, this embodiment may be provided in addition to, or as an alternative to the arm-exercising upper portion provided on the first standard 12. When provided as an alternative arm exerciser as shown in FIG. 2B, or as an alternative arm rest as shown in FIG. 2C, the upper portion of standard 12 above seat support bar 21 is eliminated, as are the slidable vertical members 33 and 33a, guides 31 and linking members 35 and 35a.
