A device for generating electrical energy from mechanical motion includes a surface float and at least one force modifier disposed at least partially within the interior of the surface float, the force modifier to receive an input force at a pumping cylinder and apply a modified force to a generator through a driving cylinder. The pumping cylinder or the driving cylinder is a tandem cylinder.

A carrier for wheeled vehicles folds down quickly and compactly, aiding in shipping and storage, and providing ease of use. The carrier includes an automobile attachment member, a first support member, and a second support member movable relative to the first member from a retracted position to an extended position. In the retracted position the second member is nested within the first member. In the extended position, the second member is extended in telescoping fashion out of the first member. The carrier also includes a third support member movable relative to the second member from a folded position to an unfolded position. An elongate upper member extending from the third member includes an elongate body and a free distal end. Adjacent spokes of a wheel are positioned about the free distal end of the elongate member and the vehicle is moved backward along the elongate body towards the third member.

A carrier rack mountable to a vehicle includes a splined member, a first arm rotationally coupled about the splined member, and a latch coupled to the first arm. The splined member includes a plurality of splines disposed along an external surface of the splined member. The splined member is disposed through an aperture in a proximal end of the first arm. The latch is configured to engage the splined member to fix the first arm about the splined member.

A carrier apparatus for a vehicle may include a bumper back beam to be drawn out and received in the bumper back beam, an adapter cover rotatably disposed at an upper portion of the carrier in an up and down direction and having an upper portion depressed to form an installation space, and a loading cover detachably connected to the installation space of the adapter cover and provided with a fixture for fixing a luggage loaded at an upper portion thereof.

The present disclosure relates to a bicycle clamp including a rail having an elongated orientation having a first end opposite a second end. A first stabilizer is attached to the rail adjacent to the first end, the first stabilizer configured to at least partially receive an associated frame of a bicycle and a second stabilizer is operably attached to the rail and movable along the rail between the first stabilizer adjacent the first end and the second end. The second stabilizer is adapted to be rigidly attached to the rail at a support position. The second stabilizer is configured to at least partially receive the associated frame of a bicycle wherein the bicycle repair clamp is configured to be placed against the associated frame of a bicycle to support the bicycle in a maintenance position.

An apparatus for loading, transporting, and unloading a two-wheeled cycle includes an elongate rail configured to support a two-wheeled cycle. A loading ramp is connected to the proximal end of the rail and is selectively deployable to substantially ground level, thereby permitting a user to roll a two-wheel cycle up the loading ramp and onto the rail. The apparatus comprises an upper initial engagement mechanism and a lower initial engagement mechanism configured removably to attach to the wheels of the two-wheeled cycle. The upper initial engagement mechanism and the lower initial engagement mechanism provide sufficient stability to permit a user to remove his or her hands from the two-wheeled cycle without the two-wheeled cycle falling off the apparatus. The apparatus comprises a final engagement mechanism configured to secure the two-wheeled cycle safely to the apparatus during transportation.

A drive mechanism for a load carrier includes a slip mechanism connected to a drive shaft and a retaining member configured to retain the slip mechanism. The slip mechanism includes a first member having a slot formed in a perimeter of the first member. The slot is configured to provide for easier relative rotation of the first member relative to the retaining member.

A drive mechanism is presented for tightening a skewer of a bicycle fork anchor upon a prong of a bicycle fork by delivering a predetermined drive-force to the skewer. The drive mechanism draws a head of the skewer against the prong thereby pinch-securing the bicycle fork to the bicycle fork anchor. The drive mechanism can include a manually operable actuator and a transmission. The manually operable actuator can be coupled to the transmission. The transmission can include a slip mechanism that only transmits driving forces to the skewer of the bicycle fork anchor that are less than the predetermined drive-force.

A foldable positioning structure for a bicycle rack includes a fixing member movable between first and second positions, an elastic assembly and a controlling assembly for being assembled to the fixing rod. The elastic assembly is assembled to a fixing rod and the fixing member so as to restrict the fixing member in the first position normally. The controlling assembly is movable between third and fourth position relative to the fixing rod and includes a pivot member and a controlling member, the pivot member is assembled to the fixing rod and pivoted to the controlling member, a free end of the controlling member is assembled to the fixing member. The fixing member is selectively restricted or nonrestricted by the movable member so that the movable member is swingable or nonswingable relative to the fixing rod.
