A rear wheel suspension adjusting arrangement for use in a vehicle includes a configuration adjusting arrangement and an activating arrangement. The vehicle includes a frame having a front and a back, a suspended rear drive wheel that supports the frame, and a suspension system for connecting the rear drive wheel to the frame. The configuration adjusting arrangement is capable of changing the positioning of the suspension system relative to the frame such that the suspension system may be moved into an uphill configuration when the vehicle is traveling uphill and such that the suspension system may be moved into a downhill configuration when the vehicle is traveling downhill. The activating arrangement activates the changing of the configuration adjusting arrangement to cause the configuration adjusting arrangement to change the positioning of the suspension system relative to the frame while the vehicle is being used.

A rack-driven seated handcycle is a semi-recumbent style two, three, or four wheeled human powered cycle that uses a linearly designed toothed rack with teeth located on the topside and bottom side of the rack, and a gear that meshes with the top teeth and a gear that meshes with the bottom teeth, at least one ratchet mechanism, and a chain coupling the upper and lower gears with the drive wheel which may be located in front or back of the rider. The rider pushes and pulls the handlebars forward and rearward to pull the rack back and forth in relation to the pinions above and below the toothed rack to drive chain(s) to propel the cycle forward. Each forward and each rearward stroke may constitute a power stroke to propel the cycle. A plurality of gear speeds is able to independently select a lever ratio for each of the forward and the rearward strokes.

A vehicle includes a front differential, a pair of constant-velocity joints, and a steering mechanism. The steering mechanism includes a pitman arm, a pair of tie rods, a pair of first link arms each connecting the pitman arm with a corresponding one of the pair of tie rods, and a pair of second link arms each connecting a corresponding one of the pair of first link arms with a body frame. In a plan view, at least a portion of each constant-velocity joint is located between first and second straight lines extending in a fore-aft direction and through first and second connectors extending between the tie rods and the first link arms. The first connector, the second connector, and at least a portion of each constant-velocity joint are located between third and fourth straight lines extending between the first and second link arms.

A position adjusting system for use in a vehicle includes a seat for supporting a rider, a rear wheel and a steerable front wheel, a steering arrangement including a handle bar for allowing the rider to control the steerable wheel, and a hub for interconnecting the components of the wheeled vehicle. The steerable wheel is steerable about at least two axes. The position adjusting system includes an adjustable seat support movably connected to the hub, an adjustable handle bar support movably connected to the hub, and a releasable position locking system configured to lock the position of the components of the vehicle relative to the hub. The hub includes a first portion and second portion, wherein the first and second portions are moveably connected to one another, such as by pivoting, sliding, or a combination of pivoting and sliding.

An electric vehicle or toy having a drag reducing system to allow the electric vehicle or toy to facilitate manual or unpowered operation. The electric vehicle or toy can include a mode-switching system which can switch the electric vehicle or toy between an electric-operation mode to a manual-operation mode. The manual-operation may decouple one or more components of the electric drive system to reduce rolling resistance or drag. The electric vehicle or toy can include one or more one-way bearings which allow components to freely rotate in a desired direction. For example, the one-way bearings can allow the electric vehicle or toy to freely rotate in a forward direction while inhibiting or preventing rotation in a rearward direction.

The invention relates to a container storage system (1) for transporting and/or for securing cargo in a container (3), and/or for partitioning the container (3), wherein the container (3) comprises side walls made of trapezoidal sheets having vertical creases (4), characterized in that the container storage system (1) comprises: At least two lateral supports (5a, b), which can be arranged vertically in at least two opposite creases (4) of at least two opposite side walls of the container (3). The supports (5a, b) each have at least one recess (13) that can be oriented to the inner chamber of the container (3) for receiving a cross bar (7). In the recess (13), at least one bearing element (11) for supporting the cross bar (7) is provided. At least one cross bar (7) is provided, which can be inserted in the at least two recesses (13) in the at least two supports (5a, b), respectively, and when installed, connects the two supports (5a, b) with one another, wherein the container storage system (1) can be assembled and dismantled without tools.
