DETAILED DESCRIPTION OF THE INVENTION

(8) The above-described drawing figures illustrate the invention, an exercise machine 10 that may be configured in either a skiing configuration or a rowing configuration.

(9) FIG. 1 is a perspective view of one embodiment of the exercise machine 10, being shown in a ski configuration. FIG. 2 is a side elevational view thereof. As shown in FIGS. 1-2, the exercise machine 10 includes a pair of ski handles 20 that are attached to a ski cable 22 (best shown in FIG. 4, and alternatively 5a or 5b) for performing ski exercises wherein the user grasps the ski handles 20 and pulls them downwardly against the resistance exerted by the ski cable 22, as described in greater detail below.

(10) The ski handles 20 are held in a raised position at a distal end 32 of a boom 30. The boom 30 may be in any form of a rigid, elongate structure that holds the ski handles 20 a suitable height above the user. The distal end 32 of the boom 30 further includes ski handle stops 24, to prevent the ski handles 20 from receding into the boom 30. As shown in FIG. 4, in this embodiment, the boom 30 is a hollow construction that houses the ski cable 22 and a row cable 72 within a pulley system 42 of a transmission 40, so that they are not exposed, the transmission 40 being described in greater detail below.

(11) The boom 30 is pivotally mounted, at a proximal end 34, to a pivot mount 36 which pivotally mounts the boom 30 on a base housing 50 such that the boom 30 is able to pivot with respect to the base housing 50 between a rowing configuration (shown in FIG. 3), wherein the boom 30 is generally horizontal, and the skiing configuration (shown in FIG. 1), wherein the boom 30 is generally vertical. The base housing 50 includes a pair of foot engagement structures 52 for receiving the user's feet while performing the rowing exercises, as discussed below. Extending from the base housing 50 are supporting legs 54, which stabilize the exercise machine 10 during use. The base housing 50 further includes a resistance device 60 for providing resistance to the ski cable 22, as well as components used in the rowing configuration, as described in greater detail below. In this embodiment, the resistance device 60 includes an air displacement fan 62 which is operated by a one way clutch 64 (shown in FIG. 5a), as described in greater detail below. The fan 62 is operably mounted on the base housing 50, and attached to the transmission 40, described further below. While one embodiment of the resistance device 60 is the fan 62 shown and described, alternative forms of resistance known to those skilled in the art may also be used, e.g., water or magnetic displacement mechanisms, etc., which should be considered within the scope of the present invention.

(12) In this embodiment, a computer display 56 extends from the base housing 50 for displaying feedback (e.g., calories burned, etc.) or entertainment (e.g., an instructional video) to the user. The base housing 50 may further include additional, optional features for providing data to the user, as is well known in the art, and should be considered within the scope of the present invention.

(13) FIG. 3 is side elevational view of the exercise machine 10 in a rowing configuration. As shown in FIG. 3, the boom 30 may be lowered to a horizontal position via the pivot mount 36, so that a seat element 76 is positioned upright to receive the user thereupon in a seated position. The seat element 76 is slidably mounted on the boom 30 with sliders 78 so that when the user is seated on the seat element 76, he or she may slide forward and back to perform rowing exercises using a row handle 70 attached to the row cable 72. The sliders 78 may be any suitable mechanism known in the art, such as wheels guided by channels within the boom 30, etc.

(14) A handle receiver 74 may be mounted on the base housing 50 to catch and hold the row handle 70 and hold it for easy access by the user while not in use. In this embodiment, the handle receiver 74 is in the form of a pair of hooks; however, in alternative embodiments, other forms of attachment mechanisms and structures (e.g., receiving structures, straps, etc.) may be devised by those skilled in the art to hold the row handle 70 in place when not in use, and such alternative structures should be considered within the scope of the current invention. The row cable 72 is operably connected to the transmission 40, mentioned above, and thus to the resistance device 60, for providing resistance to the row cable 72.

(15) FIG. 4 is a perspective view of the exercise machine 10 in the ski configuration, partially broken away to illustrate the transmission 40 for connecting the row cable 72 and the ski cable 22 to the resistance device 60. In this embodiment, the transmission 40 includes the pulley system 42 that connects the fan 62 with the row handle 70 and the pair of ski handles 20 within the hollow boom 30.

(16) FIG. 5A is a diagram of one embodiment of the pulley system 42 of FIG. 4, illustrating how the row handle 70 and the ski handles 20 may be attached to the fan 62 via the pulley system 42. As shown in FIG. 5A, in the first embodiment the transmission 40 includes the single ski cable 22 that passes through a first movable pulley 44, from one handle to another. The row cable 72 passes through an opposing pulley 46, and is connected to the fan 62.

(17) In one embodiment of FIG. 5A, a first end 23a is attached to one of the pair of ski handles 20, and the second end 23b is attached to the other of the pair of ski handles 20. The ski cable 20 extends through ski handle stops 24 (shown in FIG. 1) at the distal end 32 of the boom 30. In addition, first and second top pulleys 42a and 42b are positioned adjacent the distal end 32 of the boom 30. A top movable pulley 44 is positioned within or adjacent the boom 30, and a bottom movable pulley 46 fixedly mounted to the top movable pulley with a pulley housing 47. In this embodiment, the ski cable 20 extends from the first end 23a, through one of the ski handle stops 24, around the first top pulley 42a, around the top movable pulley 44, around the second top pulley 42b, and then back out through the other ski handle stops 24, to the second end 23b. In one embodiment, the ski cable 20 may further extend around first and second additional pulleys 43a and 43b that are each laterally spaced from the top pulleys 42a and 42b, respectively, for mounting the ski handles 20 at suitable positions relative to the boom 30.

(18) Those skilled in the art may add additional features to further facilitate this construction, and such additions within the skill of the art should also be considered within the scope of the present invention.

(19) As shown in FIG. 5A, the row handle 70 is attached to the row cable 72 which extends around a first bottom pulley 45a, around the bottom movable pulley 46, and around a second bottom pulley 45b, to where it is connected to the resistance device 60. In this manner, when the row handle 70 is pulled, the row cable 72 directly pulls on the resistance device 60, since the ski handles 20 do not allow movement of the bottom movable pulley 46. The ski handles 20, on the other hand, pull on the top movable pulley 44, which in turn (via the bottom movable pulley 46) pull upon the row cable 72, to pull the resistance device 60.

(20) FIG. 5B is a diagram of another embodiment of the pulley system 42 of FIG. 4, illustrating a second embodiment of how the row handle 70 and the ski handles 20 are attached to the fan 62 via the pulley system 42. As shown in FIG. 5B, the ski cable 22 may pass through one or more additional fixed pulleys 48 in combination with one or more top moveable pulleys 44, to achieve a varied gear ratio to adjust the force ratio-metrically between the ski handles and the row handle. This enables the fan 62 to provide resistance to the row handle 70 and to the ski handles 20, enabling exercises using these handles.

(21) The system 10 further has a recoil device 80 within the base housing 50 that provides force to return the cables 72 and 22 to their respective starting positions after each use. In the embodiment of FIGS. 5a and 5b, the recoil device 80 is in the form of a coiled spring, but in other embodiments may comprise a different recoil mechanism known in the art (e.g., a resilient band, other form of spring, etc.).

(22) In this embodiment, the cable 72 wraps around a spool 82 to drive the resistance device 60. In other embodiments, the resistance device 60 may be driven with a chain and sprockets, toothed belt, frictional belt, or other means known to those skilled in the art.

The terms approximately and about are defined to mean+/10%, unless otherwise stated. Also, the terms have, include, contain, and similar terms are defined to mean comprising unless specifically stated otherwise.
