Abstract: A roller pump includes a stator with a pump bed formed therein, and a rotor for acting on a hose inserted into the pump bed in arcuate form. The ends of the hose are guided out of the pump bed in a crossed configuration.

Abstract: The invention relates to a roller pump consisting of a stator with a pump bed formed therein and a rotor for acting on a hose inserted into the pump bed in arcuate form. In accordance with the invention, the flow paths associated with the ends of the tube guided out of the pump bed cross.

Abstract: A stroller includes a frame having a frame leg and a frame joint at which the frame leg is coupled to the frame. The frame joint is configured to allow retraction of the frame leg to a folded position. A handle is attached to the frame at a pivot joint, the pivot joint being configured for rotation of the handle between first and second operational orientations. The pivot joint is further configured for rotation of the handle from the first or second operational orientations to a storage position aligned with the folded position of the frame leg. In some cases, a front frame leg and a rear frame leg are coupled to the frame joint, the frame joint being configured to allow the front frame leg and the rear frame leg to retract to respective folded positions in which the stroller is supported in an upright orientation.

Abstract: A stroller includes a base frame assembly and a seat assembly supported by the base frame assembly. A seat leg extending from the seat assembly is slidably engaged with the base frame assembly for movement of the seat assembly relative to the base frame assembly from a first seating height level to a second seating height level. In some cases, a support post of the base frame assembly is oriented in a telescopic arrangement with the seat leg along a generally vertical axis. In some cases, one or more slider mechanisms slidably couple the seat assembly to the base frame assembly, where each slider mechanism has a lock to secure the seat assembly at either the first seating height level or the second seating height level.

Abstract: A stroller is provided having a stroller frame supporting a stroller seat. The stroller frame includes a linkage that facilitates collapsing or folding of the stroller frame from an in-use configuration to a folded or collapsed configuration, and unfolding of the stroller frame from the folded or collapsed configuration to the in-use configuration. The linkage also facilitates adjustment of the stroller seat height between at least two vertically offset positions.
