  • Publication number: 20130264799
    Abstract: An infant stroller apparatus includes a rear leg frame including a first side segment, a handle having a second side segment formed by at least a first and a second tubular member telescopically assembled with each other, an impeding part assembled with the second side segment and operable to create an interference that blocks retraction of the second tubular member into the first tubular member, and an armrest pivotally connected with the second side segment and provided with an actuating member disposed adjacent to the impeding part. A rotation of the armrest in a direction for collapsing the infant stroller apparatus can cause a displacement of the actuating member, which drives the impeding part in movement to remove the interference and allow retraction of the second tubular member into the first tubular member.

    Abstract: A foldable stroller has a frame assembly with a frame fold joint and is reconfigurable between an in-use configuration and a folded configuration. A child support structure is repositionable between a usable state on the frame assembly in the in-use configuration and an unusable state not suitable to support a child on the frame assembly. An interlock mechanism cooperates with the child support structure and is movable between a locked state preventing the frame assembly from being folded from the in-use configuration to the folded configuration and an unlocked state permitting the frame assembly to be folded. With the frame assembly in the in-use configuration and the child support structure on the frame assembly in the usable state, the interlock mechanism is retained in the locked state. The interlock mechanism is unlocked when the child support structure is moved to the unusable state.

  • Patent number: 8336904
    Abstract: A modular wheelchair comprises a number of different modules that include a chassis module with frame members substantially centered along a center plane through the chassis, so that the chassis is able to lay flat when the modules are dissembled. The chassis is connected to a drive module by a single plug/receiver mechanical coupling that may include opposite end geometries. When the plug is in a seated position within the receiver, first end geometries of the two components mate mechanically to resist radial movement, while the second end geometries mate mechanically to resist both radial movement and rotation about an axis of the coupling. Additionally, axial movement in one direction is resisted, with the coupling oriented to apply gravitational force to resist axial movement in the opposite direction. The same arrangement may be used for a seat module.
