Each carriage has a platform for the attachment of one of the skater's feet, said platform altering its angle of inclination upon displacement of the associated carriage from the initial position in the same way as a skate when cutting the ice. The lateral displacement of each carriage occurs against the action of a force which is adjustable.

The prior art does not teach a machine of simple and inexpensive construction capable of true skating motion. The present invention fulfills this need and provides further related advantages as described in the following summary.
- The present invention teaches certain benefits in construction and use which give rise to the objectives described below.
- Skating requires a side-to-side motion which up until now has been difficult to reproduce in a simple and inexpensive exercise machine. See my previous attempt described above in U.S. patent 6,234,935. However, I have now devised a much simplified and improved manner for providing skating motion in an exerciser that may be manufactured at low cost and is much more reliable. In the present invention a pair of a skater foot supports are joined with a skating motion director including, a simple crank interconnected with the foot supports by a pivotal linkage, such that as the crank rotates in a circle, one of the foot supports is pulled and the other pushed during a first one-half of the circle rotation, while, the reverse occurs during the second one-half of the circle rotation. In this way, the supports move in alternating arc motions from side to side simulating skating movements of the skater's feet. The foot supports are mounted at an angle so that each support moves to an elevated position when it swings to the inside lateral position. The crank is rotationally engaged with a flywheel through a mechanical drive train, enabling the flywheel to rotate at a speed greater than that of the crank whereby the foot engaging means move with a skating motion for exercising a skater and this motion is smoothed using the flywheel's energy. A handle moves from side-to-side coordinated with the foot supports so that the skater may maintain balance. Such a machine has the advantage of exercising the entire body, legs and arms without jarring actions, in a highly smooth and fluid motion that is soothing as well.

- Another objective is to provide such an invention of simple design and manufacture.
- A further objective is to provide such an invention enabling true skating motion.
- A still further objective is to provide such an invention with variable resistance adjustment.
- Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.
- The accompanying drawings illustrate the present invention. In such drawings:
- Figure 1 is a perspective view of the preferred embodiment of the invention;
- Figures 2-4 are bottom plan views thereof showing the invention in three stages of manipulation according to how it is used in practice; and
- Figures 5-8 are schematic diagrams of alternative linkage interconnections thereof.
-
- The above described drawing figures illustrate the invention in at least one of its preferred embodiments, which is further defined in detail in the following description.
- The present invention is a skating motion exercise apparatus comprising a pair of a means for engaging a
foot 10, 10' of a skater, and a means for directingskating motion 20 to the pair offoot engaging means 10, 10'. Thefoot engaging means 10, 10' are each preferably a treadle of such size and shape as to accommodate a foot of the skater and may include a strap for engaging the foot securely to the treadle, while allowing the heel of the foot to lift off the treadle. This may be asimple instep strap 12 as shown in Fig. 1, or a toe cup, both of which are well known in the prior art. Thefoot engaging means 10, 10' further include rigid rods 11. The skating motion directing means 20 includes, a means for cranking 30, which may be a simple crank system as clearly shown in Fig. 1, interconnected with the pair offoot engaging means 10,10' by a pivotal means for linking, i.e., the pair oflinks means 30 rotates in a circle, one of thefoot engaging means 10 is pulled during a first one-half of the circle of rotation, while, simultaneously, the other of the foot engaging means 10' is pushed, and during a second one-half of the circle of rotation, the other of the foot engaging means 10' is pulled, while simultaneously, the one of thefoot engaging means 10 is pushed. Thefoot engaging means 10, 10' is pivotally mounted atpoints means 30 rotates, driven by the pair offoot engaging means 10, 10'. - Preferably, the energy storing means 70 is a flywheel mounted for rotation and enabled by a drive train 75 to rotate at a speed greater than that of the cranking
means 30. In Fig. 1 it is shown that a preferred manner of accomplishing this is to drive themeans 70 by a chain or belt with a rotational ratio of at least several turns offlywheel 70 to each rotation of the cranking means 30 as shown. - Preferably, as shown in Fig. 1, the
foot engaging means 10,10' are each mounted at an angle such that when one of the foot engaging means 10 moves toward an outboard lateral position, during the alternating lateral movements of the foot engaging means, the other one of the foot engaging means 10' moves toward an elevated inboard lateral position, and visa-versa. This improves the ability of the skater to shift weight and improves the simulation of skating motion. As shown in Fig. 1 the mounting angle is defined by angular dimension "A" below the horizontal. - Preferably, an
upright handle 80 is engaged with the cranking means 30 such that it moves from side-to-side in lateral reciprocating motion. This is accomplished by pivotally mounting thehandle 80 and attaching thehandle 80 to the axle of the cranking means 30 in such manner that each rotation of the crankingmeans 30 pulls the handle to the side which extends the treadle to the rear, as shown in Fig. 3. - A
friction pad 100 is brought into contact with the cranking means and is adjustable for enabling a range of difficulty in the present invention exerciser. Alternatively, thefriction pad 100 may be mounted for contact with the flywheel. - Figs. 5-8 show alternative linkage arrangements that may be used in the present invention to assure that both foot engaging means move in concert. Other alternate linkage arrangements would be obvious to those of skill in the art.
- While the invention has been described with reference to at least one preferred embodiment, it is to be clearly understood by those skilled in the art that the invention is not limited thereto. Rather, the scope of the invention is to be interpreted only in conjunction with the appended claims and it is made clear, here, that the inventor(s) believe that the claimed subject matter is the invention.
Claims (6)
- A skating motion exercise apparatus comprising: a pair of a means for engaging a foot of a skater; means for directing skating motion to the pair of foot engaging means; the skating motion directing means including, a means for cranking interconnected with at least one of the pair of foot engaging means by a pivotal means for linking, such that as the cranking means rotates in a circle, the foot engaging means move in alternating lateral arcs simulating skating motion of a skater's feet.
- The apparatus of claim 1 further comprising an energy storing means engaged with the cranking means for smoothing the motion of the cranking means.
- The apparatus of claim 2 wherein the energy storing means is a flywheel enabled by a drive train to rotate at a speed greater than that of the cranking means.
- The apparatus of claim 1 further comprising an upright handle engaged with the cranking means and enabled thereby to move in side-to-side lateral reciprocating motion corresponding to rotation of the crank.
- The apparatus of claim 1 wherein one of the foot engaging means is engaged with the cranking means, the other of the foot engaging means pivotally engaged with the one of the foot engaging means for moving in correspondence therewith.
- The apparatus of claim wherein the foot engaging means are each mounted at an angle such that when one of the foot engaging means moves toward an outboard lateral position, during the alternating lateral movements of the foot engaging means, the other one of the foot engaging means moves toward an elevated inboard lateral position.
