In an exercise apparatus resistance may be provide by the inertia of unsprung mass. The exercise apparatus may include a frame and dependently coupled foot support members movably connected to the frame. The foot support members carry a weight mass which may be adjusted to increase or decrease the unsprung mass providing inertial resistance to linear or arcuate acceleration.

Inertial resistance exercise apparatus

An exercise apparatus having multiple exercise modes of operation may include a frame supporting generally vertically oriented reciprocating members spaced apart and in substantial parallel relationship to one another. Reciprocating leg members may include foot supports secured at the lower distal ends thereof. Reciprocating arm members may include hand grips coupled proximate the upper distal ends of the arm members. The arm members and leg members may be operably coupled in multiple configurations for a user to perform various climbing exercise movements.

Climbing exercise apparatus

A climbing exercise apparatus having ipsilateral and contralateral modes of operation may include a frame supporting generally vertically oriented frame members in spaced apart relationship to one another fixedly secured to a base of the frame. The vertically oriented members may support endless belt and pulley systems. Handlebars and foot supports may be connected to upper and lower carriage members engaging the endless belt to establish ipsilateral and contralateral configurations of the climbing exercise apparatus.

An exercise apparatus having homolateral and contralateral modes of operation may include a frame supporting generally vertically oriented reciprocating members. The reciprocating members may include foot supports secured at the lower distal ends thereof, and handlebars movably secured proximate the upper distal ends of the reciprocating members. The handlebars may be configured for homolateral and contralateral operation of the exercise apparatus.

A climbing exercise apparatus having homolateral and contralateral modes of operation may include a frame supporting generally vertically oriented movable slide members in spaced apart relationship to one another. The slide members may include foot supports secured at the lower distal ends thereof and handlebars in adjustable telescopic relationship with the slide members. Handgrips may be rotatably mounted proximate the upper distal ends of the handlebars. The handgrips may be rotatably about a canted axis which is canted relative to the longitudinal axis of the handlebars and selectively locked for homolateral and contralateral operation of the climbing exercise apparatus.

A climbing exercise apparatus having ipsilateral and contralateral modes of operation may include a frame supporting movable generally vertically oriented members. The vertically oriented members may include arm and foot support members rotatably connected to carriage members movably supported on the frame. The climbing exercise apparatus may include three-dimensional movement capabilities for a user's arms and feet to move through three dimensional paths of motion during an exercise activity.

A climbing exercise apparatus having homolateral and contralateral modes of operation may include a frame supporting generally vertically oriented reciprocating members. The reciprocating members may include foot supports fixedly secured at the lower distal ends thereof, and handlebars secured proximate the upper distal ends of the reciprocating members. The reciprocating members path of motion may include vertical and lateral components.

A watercraft propulsion apparatus includes an eccentric crank assembly operatively connected to a pair of fins adapted to sweep back and forth in a generally transverse direction relative to a longitudinal axis of the watercraft. The fins may be rotatable about a first axis coplanar to the longitudinal axis of the watercraft. A drive linkage assembly operatively connecting the eccentric crank assembly to the pair of fins imparts a torque force to oscillate the pair of fins. The oscillating fins provide a propulsive force to propel the watercraft longitudinally forward during both oscillating directions of the fins as they sweep back and forth.

A climbing exercise apparatus having homolateral and contralateral modes of operation may include a frame supporting generally vertically oriented movable slide members in spaced apart relationship to one another. The slide members may include foot supports secured at lower distal ends thereof and handlebars in adjustable telescopic relationship with the slide members. Handgrips may be rotatably mounted proximate to upper distal ends of the handlebars. The handgrips may be rotatably about a canted axis which is canted relative to a longitudinal axis of the handlebars and selectively locked for the homolateral and contralateral modes operation of the climbing exercise apparatus.

A writing instrument may include an upper barrel rotatably connected to a lower barrel. Writing fluid reservoirs may be housed in the upper barrel. A writing tip secured to the lower barrel may be in selective fluid communication with the writing fluid reservoirs. The upper barrel may be rotatable relative to the lower barrel of the writing instrument.

A watercraft propulsion apparatus includes an eccentric crank assembly operatively connected to a pair of fins adapted to sweep back and forth in a generally transverse direction relative to a longitudinal axis of the watercraft. The fins may be rotatable about a longitudinal shaft fixedly secure to the bottom of the hull of the watercraft. A drive linkage assembly operatively connecting the eccentric crank assembly to the pair of fins imparts a torque force to oscillate the pair of fins. The oscillating fins provide a propulsive force to propel the watercraft longitudinally forward during both oscillating directions of the fins as they sweep back and forth.

A swim fin may include a foot pocket configured to receive a foot of a swimmer and a fin blade extending from the foot pocket. A relatively rigid substrate chassis may be bonded to the foot pocket. The fin blade may be relatively flexible. Fin rails may extend along the lateral edges of the fin blade. The fin rails may include a fin spine comprising a plurality of fin spine segments in linear configuration. The fin spine may be configured to provide a swim fin with predetermined hydrodynamic characteristics. The swim fin may flex within a maximum angle of attack that may be variable and dynamically changed, within a predetermined maximum attack angle range, as a function of the kicking force generated by a swimmer during a kicking cycle.

In a gravity fluid filtration system, upper and lower fluid reservoirs may be mated together. Unfiltered fluid may be supplied to the upper reservoir. One or more filters provide fluid communication between the upper and lower fluid reservoirs. Fluid may pass through the filters into the lower fluid reservoir. The weight of the fluid in the gravity filtration system may be monitored to maximize the fluid flow rate without loss of fluid by supporting the fluid reservoirs on a moveable platform interconnected to a stationary base by a force reactive linkage. Automatic fill components may be provided for automatically actuating a fluid supply valve connected to an unfiltered fluid source. As filtered fluid is withdrawn from the lower reservoir, actuation of the fluid supply valve to an open position may permit unfiltered fluid to be supplied to the upper reservoir. Supply of unfiltered fluid to the upper reservoir may be stopped upon actuation of the fluid supply valve to the closed position. Actuation of the fluid supply valve is a function of the weight of the fluid in the filtration system and/or vertical travel of the moveable platform.
