Abstract

An electrically driven, continuous track treadmill having a frame comprising a first section with a second section pivotably connected to a rear end thereof. The treadmill is adjustable between an operational position where the first and second sections are substantially horizontally aligned, and a folded position where the second section is pivoted onto said first section, such that an upper surface of the second section abuts an upper surface of the first section. A handle is pivotally connected to the first section of the frame and extends upwardly away therefrom when the treadmill is in the operational position. The handle pivots into abutting contact with a lower surface of the second section when the treadmill is in the folded position. The treadmill preferably is also provided with an inclination adjustment assembly that is selectively activatable to move the frame between a neutral position, a positively inclined position and a negatively inclined position relative to the floor surface. The treadmill is further provided with a shell configured to resemble a coffee table which is positioned over or around the treadmill when in the folded position. The treadmill therefore can be stored in plain sight.

2. The folding treadmill as defined in claim 1, wherein the first section remains stationary and only the second section moves when the treadmill is adjusted between the operational and folded positions.

3. The folding treadmill as defined in claim 2, wherein the treadmill is movable between the operational and folded positions without requiring pre-loosening of the track.

4. The folding treadmill as defined in claim 1, wherein the first section of the frame comprises:

a substantially vertical first leg; and

a substantially horizontal second leg that is fixedly connected to said first leg;

wherein said handle extends outwardly away from said first leg, and wherein the second section of the frame is pivotably connected to the second leg.

5. The folding treadmill as defined in claim 4, wherein the handle has a first position where the handle extends upwardly away from the first leg when the treadmill is in the operational position;

and a second position where the handle is in one of abutting contact with and in proximity to a lower surface of the second section when the treadmill is in the folded position; and

wherein the handle is movable between the first and second positions.

6. The folding treadmill as defined in claim 1, further comprising:

a joint between the rear end of the first section and a front end of the second section; and

a support foot fixedly secured to a lower surface of the first section proximate the joint.

7. The folding treadmill as defined in claim 6, wherein the support foot extends for a distance rearwardly from the rear end of the first section and abuts a portion of a lower surface of the second section when the treadmill is in the operational position.

8. The folding treadmill as defined in claim 6, wherein the support foot has a floor-engaging wall;

and wherein said floor-engaging wall is arcuate in shape.

9. The folding treadmill as defined in claim 6, further comprising:

a pivot at a top end of said joint for pivotably connecting said first and second sections.

10. The folding treadmill as defined in claim 1, further comprising an outer shell that is selectively positionable around the frame when the treadmill is in the folded position so as to hide the same from view.

11. The folding treadmill as defined in claim 10, wherein the outer shell has the appearance of a piece of furniture.

12. The folding treadmill as defined in claim 11, wherein the outer shell comprises a top wall and a plurality of side walls that extend outwardly away from the top wall;

and wherein the top wall is fixedly secured to the side walls to form a box that defines an interior cavity into which the treadmill in the folded position is received.

13. The folding treadmill as defined in claim 12, wherein the shell further includes a bottom wall and two or more side walls are pivotally secured thereto and are movable to engage the top wall of the shell.

14. The folding treadmill as defined in claim 1, further comprising an inclination assembly for adjusting the inclination of the frame relative to a floor surface upon which the frame rests;

wherein the inclination assembly is selectively activatable to adjust the inclination of the frame between a neutral position and a positively inclined position.

15. The folding treadmill as defined in claim 14, wherein the inclination assembly is further selectively activatable to adjust the frame to a negatively inclined position.

16. The folding treadmill as defined in claim 14, further comprising:

a joint between the first and second sections;
