Abstract: An item of exercise equipment with a movable support that is movable in a fore-aft direction and simultaneously movable laterally, e.g. about a tilt axis. The exercise equipment may be a cycle mounted to a base. A roller and track arrangement may be provided between the cycle and base, to provide movement of the cycle in the axial direction and in a tilt direction relative to the base. The roller and track arrangement may be one or more curved roller and track engagement surfaces that extend in the axial direction and provide a gravity bias of the platform toward an axial neutral position. The cycle and base include a tilt biasing arrangement for biasing the cycle toward a tilt neutral position relative to the base.

Abstract: A bicycle parking rack includes a tray having a stationary wheel engagement structure that engages a bicycle wheel on one side of the center of the wheel. A movable wheel engagement member is arranged to engage the bicycle on the other side of the center of the wheel, to apply a clamping force on the wheel and to maintain the the bicycle in an upright position. The rack may include lower parking stations in which at each lower station the front bicycle wheel is clamped between the wheel engagement structure and the movable wheel engagement member, and upper parking stations in which at each station the rear wheel engages the wheel engagement structure and the front wheel is engaged with the wheel engagement member. At each upper station, the tray is movable between a loading position and a storage position via an elevated track and trolley arrangement.

Abstract: An Example can include an elongate pump barrel extending along a length and defining an elongate hollow piston chamber. The Example can include a piston slidably movable within the piston chamber to compress air within the piston chamber. The Example can include a piston rod connected to the piston. The Example can include a handle connected to the piston rod to reciprocally slide the piston in the piston chamber. The Example can include a piston rod seal disposed around the piston rod and coupled with the elongate pump barrel. The Example can include a downward opening air intake passage, located away from the rod seal, in fluid communication with a top of the piston.

Abstract: An exercise arrangement includes a movable support that is movable in a fore-aft direction and simultaneously movable laterally, e.g. about a tilt axis. The support may be a platform movably mounted to a base. A roller and track arrangement may be provided between the platform and the base, to provide movement of the platform in the axial direction relative to the base as well as an axially neutral position of the platform relative to the base. The roller and track arrangement may be in the form of one or more curved roller and track engagement surfaces that extend in the axial direction and that provide a gravity bias of the platform toward the neutral position. The roller and track arrangement may provide tilting movement of the movable platform about the tilt axis. A tilt biasing arrangement biases the platform toward a neutral tilt position relative to the base.

Abstract: A collapsible boundary delineator includes a base for placement on a ground surface and a divider member that is movable relative to the base between a raised, operative position and a lowered, inoperative position. The base includes a pair of base members that are engageable with each other, and the divider member includes a pair of spaced apart ends secured one to each of the base members. When the base members are engaged together the divider member is in the raised, operative position and when the base members are disengaged from each other the divider member is in the lowered, inoperative position. A selectively releasable latch arrangement carried by the base members is movable between a latching position for selectively maintaining the base members in engagement with each other and a release position for selectively enabling the base members to be moved apart from each other.

Abstract: A vehicle-mounted equipment carrier includes a mounting member, an equipment support, and a mast. A lower end of the mast is pivotably interconnected with the mounting member and an upper end of the mast supports the equipment support. The mast is pivotable between an upright position for transport and a lowered position that positions the mast rearwardly of the vehicle. A movable connection between the mast and the equipment support lowers an inner end of the equipment support while raising an outer end when the mast is lowered, and raises the inner end of the equipment support while lowering the outer end when the mast is raised. The center of gravity of the equipment carried by the equipment support remains at a constant elevation during movement of the mast between the upright position and the lowered position.

Abstract: A hitch-type equipment carrier for mounting to a vehicle includes a coupling member, a brace member fixed to the coupling member, and a wedge member that is movable relative to the coupling member. A manually operable actuator is positioned between the brace member and the wedge member. When the coupling member is positioned within the hitch receiver passage, operation of the actuator moves the wedge member in a first direction toward the open end of the hitch receiver passage. The wedge member moves outwardly upon advancement through the open end of the hitch receiver passage. Such transverse movement of the wedge member brings the wedge member into contact with one or more walls of the hitch receiver, which forces the coupling member against one or more of almost walls of the hitch receiver for preventing rattle of the coupling member within the passage of the hitch receiver.

Abstract: A system is provided for determining total exerted power value that is determined based on power measured at only one side of a bicycle by determining a side-to-side pedaling power asymmetry and estimating the total exerted power as a function of values of the one-sided power measurement and the side-to-side pedaling power asymmetry.

Abstract: A bicycle repair stand includes an upright column. A first repair station includes a repair rack extending from the upright column in a first direction. The repair rack retains a bicycle at an elevated position relative to a column base. A tool storage face is provided along an exterior of the upright column. At least one retractable tool is coupled along the tool storage face. The at least one retractable tool includes a tool, a cable coupled with the tool, and a retraction mechanism coupled with the cable and configured to pull the tool toward the tool storage face when released by an operator.

Abstract: A bicycle rear derailleur has a mounting base, a moveable base, and a friction assembly. The moveable base has an axle. The friction assembly is mounted in the moveable base and has a driving disk, a driven disk, multiple rotating members, and a friction member. The driving disk is connected with the axle in a non-rotatable manner. The driven disk is rotatably and axially moveably mounted in the moveable base. Each disk has multiple curved rotating member guiding recesses. Each rotating member guiding recess of the driving disk has a depth decreased along a first rotating direction. Each rotating member guiding recess of the driven disk has a depth decreased along a second rotating direction. The rotating members are mounted respectively in the rotating member guiding recesses. The friction member is mounted in the moveable base in a non-rotatable manner and abuts the driven disk.

Abstract: A system for determining power expended by a bicyclist while riding a bicycle based on speed measurements or sensed-speed values. The system includes a sensing device arranged for detecting a speed-related value of the bicycle and a processor that communicates with the sensing device. The processor is configured to determine a change in the speed-related value and to determine a power value based on the change in the speed-related value.
