Abstract: A food chopper includes a housing and a central shaft supported in a vertically movable configuration inside the housing. The central shaft has a lower end with at least one center blade, an upper end operably connected to a plunger, and a middle segment with two lateral arms. Two blade assemblies are rotatably connected to the two lateral arms of the central shaft. Each of the two blade assemblies includes a shaft connected to an outer blade. The vertical motion of the central shaft is converted into rotational motion of the blade assemblies using a conversion mechanism operably connected to each of the two blade assemblies. Depressing the plunger causes the at least one center blade of the central shaft to move vertically downward within the housing and the two outer blades to move vertically downward and rotate within the housing.

Abstract: An inertial exercise device includes a hollow outer ball and a weighted inner ball elastically suspended inside the outer ball by at least two opposing suspension members. The weighted inner ball may contain a fluid mass. The hollow outer ball, the weighted inner ball and the at least two opposing suspension members may all be integrally formed with each other. In one embodiment, the outer ball, the inner ball, and the suspension members are all formed from integral segments of a pliant tube. The hollow outer ball is formed by everting first and second end segments of the tube over the middle segment of the tube and joining the first and second end segments of the tube together at their openings. The weighted inner ball is formed from the middle segment of the tube which, in one embodiment, is a bulge in the tube.

Abstract: A footwear covering system includes a piece of footwear having a sole with a perimeter boundary material and a footwear cover attached to the piece of footwear. The footwear cover includes an attachment device, a sheath attached to the resilient clamp and forming an elongate arcuate cover and indicia on the sheath portraying the face of a character. The attachment device may include a snap-fit connector and/or a resilient clamp with an inner surface with grippers, the resilient clamp being shaped to conform with the perimeter boundary material of the sole of the piece of footwear. The footwear cover may include a battery compartment housing a battery, and in some embodiments the snap-fit connector comprises conductors that establish an electrical connection when the snap-fit connector is mated with a complementary connector on the piece of footwear.

Abstract: A resistance chair includes an elevated stationary seat with a front edge and a back edge. An arm is rotatably engaged with the back edge of the seat and is rotatable to a position below horizontal with respect to the elevated stationary seat. A back support is secured to the arm and supports the back of a user sitting on the elevated stationary seat. At least one resistance element is connected to the elevated stationary seat and urges the first arm to an upright start position and assists a user performing an abdominal crunch to return to an upright abdominal crunch position from a fully extended abdominal crunch position with the arm below horizontal with respect to the elevated stationary seat. The resistance element also resists against rotation of the arm away from the upright start position and resists against the user moving from the upright abdominal crunch position to the fully extended abdominal crunch position.

Abstract: A resistance chair with wheels assists users with performing correct abdominal crunches by guiding the user's effort. The resistance chair includes a seat operably coupled to at least one hinged arm with back support that extends to support the user's back and assist in the crunch recovery following the crunch extension.

Abstract: An adjustable inertial exercise device has an elongate member with first and second threaded portions with opposite-handed threads. First and second nuts, each having at least one radial flange, are respectively rotatably engaged with the first and second threaded portions of the elongate member. A sleeve is slidably mounted over the first and second nuts. The sleeve has an internal bore with first and second bearings and at least one longitudinal groove slidably engaged with the radial flanges of the first and second nuts. Elastic resistance elements interface between the first and second nuts and the first and second bearings. Rotation of the elongate member relative to the sleeve one direction causes the nuts to move apart from one another compress the resistance elements. Rotation of the elongate member relative to the sleeve in the opposite direction causes the nuts to move toward one another and expand the resistance elements.

Abstract: In one aspect of the disclosed embodiments, an inertial exercise device has an elongate member with opposing first and second end portions, and a sleeve movably coupled to the elongate member and disposed between the first and second end portions of the elongate member. A first elastic resistance element interfaces between the elongate member and the sleeve. A user-induced rhythmic movement of the sleeve along the elongate member alternatively toward the opposing first and second end portions causes the first elastic resistance element to alternately compress and extend as the first and second end portions of the elongate member oscillate relative to the sleeve.
