Foldable recumbent stepper exercise device

Abstract

A portable recumbent stepper device may comprise a frame which may have a main body in the form of a beam extending fore-to-aft. The frame may also include a front leg and a rear base both for providing vertical and lateral support. The device may include an upward frame element fixedly joined to the fore end of the main body. A pair of foot pedals may be hingedly joined to the upward frame element. A pair of upwardly extending handles may be hingedly joined to the upward frame element and to the foot pedals so that they move in unison with the foot pedals, and the handles may be swept rearward to accommodate a seated user. A pair of resistance elements may be joined to the frame at one end and to one of the pair of foot pedals at another end.

IV. DETAILED DESCRIPTION OF THE INVENTION

(11) Recumbent stepper devices according to embodiments of the invention may include a small-profile structure enabling a user to exercise with the device while seated in an arbitrary user-provided seat or chair. Furthermore, the device may include handles adapted to enable a rowing motion performed by a user while simultaneously engaging in a stepping motion. Advantageously, the handles may be configured or configurable into a rearwardly swept orientation to accommodate a seated user. More specifically, during use the device may be placed in front of a user-provided seat, thus sweeping the handles rearward would better position the handles within reach of a seated user thereby allowing the user to grip the device in a more natural position. Embodiments may also include foldable, collapsible, and/or stowable components so that the device may be packed and easily carried or otherwise transported more or less by hand. Such embodiments may advantageously include a handle built into the frame and/or chassis of the device.

(12) Referring now to the drawings wherein the showings are for purposes of illustrating embodiments of the invention only and not for purposes of limiting the same, FIG. 1 is an elevation view of an embodiment 100 having a chassis 112. Thus, the frame components of this embodiment 100 are largely hidden from view. The device includes a pair of upwardly extending handles 106, which in this embodiment each comprise a pair of telescoping length-adjustment components for changing the overall length of the handles 106. Particularly, the handles 106 include an upper shaft 106A and a lower shaft 106B which receives the upper shaft 106A in a telescoping relation. The length of the handles 106 can be adjusted by loosening knob 110, changing the relative position of the upper and lower shafts 106A, 106B and retightening the knob 110. Other length-changing means are known in the art and within the scope of the invention. For instance, the handles may be foldable about a hinged joint located in a middle region of the handles 106. Advantageously, such a hinged joint may include components for locking the handles 106 in a selected configuration, i.e. folded or unfolded.

(13) In the embodiment 100 of FIG. 1 the handles 106 connect to the pedals 108, which are in turn hingedly connected to the frame of the device. Thus it may be said that the handles 106 attach to the frame of the device through a common joint with the pedals 108; both the pedals and the handles owe their hinged motion to the same joint although one may be connected to the joint through the other. Accordingly, the upwardly extending handles 106 move in unison with the pedals 108. In a related embodiment the handles 106 and the pedals 108 may each directly connect to a hinged joint in a fixed relation to each other. Thus, the handles 106 and pedals 108 may still move in unison.

(14) As shown in FIGS. 1, 2 and 3 embodiments may include a pair of front legs 102 which may provide vertical as well as lateral support to a fore end of the device. Similarly, a rear base 104 may be included to provide vertical and lateral support to the aft portion of the device. The front legs 102 and/or the rear base 104 may be foldable; however, in some embodiments their configuration may be fixed. In embodiments having fixed front legs 102 and/or rear bases 104 the leg 102 and base 104 elements may be sized and configured to be sufficiently compact to render the device portable without folding. Additionally, embodiments may include a display unit 114 for indicating, e.g. the duration and/or intensity of exercise, or other parameters which may be useful or convenient to a user.

(15) FIGS. 4 through 7 illustrate a second embodiment 200 lacking a chassis, or where the chassis has been removed for viewing the internal components. FIG. 4 illustrates and embodiment 200 having a pair of rearwardly swept handles 106, a rear base 104 and a pair of front legs 102. The embodiment 202 also includes a display mounted at the top of a central post 202. FIG. 5 is a top view wherein the pedals 108 and the display are more clearly visible. Turning to FIG. 6, the embodiment 200 is shown in side view in more detail. From this perspective T-shaped beam 204 is shown as part of the rear base 104 which is joined to an aft end 206B of the main body 206. Also visible is one of the front legs 102 which is joined to the main body 206 at its fore end 206A. A resistance element 208 is shown being hingedly joined at a fore end 208A to the frame and at its aft end 208B to the underside of a pedal 108.

(16) From the side view perspective of FIG. 6 the relationship of the handles, pedals, and frame also become clearer according to this embodiment 200. The pedals 108 are mounted on a pedal base 210 which is welded to a hub 214. The upwardly extending handle 106 is shown forming an L-shaped portion 212 at its base which is welded 216 to the hub 214 at about ninety degrees relative to the pedal base 210; however, the precise angle is not critical. The entire assembly of the handle 106 and pedal base 210 is hingedly joined through the hub 214 to an upward frame element 218. The extension of the upward frame element 218 is regarded herein as upward although it is necessarily directly vertical in a deployed configuration relative to the floor.

(17) Turning to the front view shown in FIG. 7, the hinge joint 220 between the hub 214 and the upward frame element 218 is visible. Also shown is that the front legs 102 of this embodiment 200 have several components. A top cross member 226 joins to the base of the upward frame element 218 through a weld joint, and a pair of legs 222 extend downward therefrom and attach to a bottom cross member 224 through another weld joint.

(18) Finally, FIGS. 8A and 8B illustrate how an embodiment may fold or collapse to make it more portable. FIG. 8A shows a deployed configuration focusing on the position of key frame elements and support members. FIG. 8B illustrates a collapsed or folded configuration, again focusing on the same key frame elements and support members.

(19) It will be apparent to those skilled in the art that the above methods and apparatuses may be changed or modified without departing from the general scope of the invention. The invention is intended to include all such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
