A guide system includes a first guide rail for guiding a door wing, a second guide rail for guiding the door wing. A carrier can move the door wing relative to the second guide rail in a direction extending transversely to the longitudinal direction of the first guide rail. A drive device has a force storage member, and the carrier can be at least partially ejected by the drive device from the retracted position of the carrier by a force of the force storage member. The drive device includes a coupling portion and a control curve, and the coupling portion and the control curve are decoupled over a large part of the movement of the carrier between the extended position and the retracted position. The carrier can be retracted into the retracted position starting from a position immediately before the retracted position when the coupling portion couples with the control curve.

A fluid damping apparatus includes a housing enclosing a chamber retaining a damping fluid, a piston disposed in the housing chamber and movable between a first end position and a second end position, and a variable volume element disposed in the housing chamber having a first size occupying a first volume in the housing chamber. Increased fluid pressure of the damping fluid (e.g., resulting from increased temperature of the fluid damping apparatus and associated expansion of the damping fluid) compresses the variable volume element to a second size occupying a second volume in the housing chamber smaller than the first volume, to permit expansion of the damping fluid, thereby limiting fluid pressure of the damping fluid.

A storage container for a rideable saddle vehicle, the container including a containment body having a base and a cover hinged to the base and adapted to be pivotally moved along a stroke extending between an angular closing position and an angular opening position, where the storage container has at least one braking device coupled to, or integrated in, the containment body, which is adapted and configured to slow down the movement of the cover along at least part of the stroke.

The present invention relates to a device (4) for closing a door (1) which is rotatably constrained to a relative anchoring structure (2) and movable between a closing position and a maximum opening position, said anchoring structure (2) being either a fixed structure or a further door. Said device (4) comprises: a first fixing element (5) fixable, in use, to the door (1) or to the anchoring structure (2) of the door (1); a second fixing element (6) fixable, in use, to the anchoring structure (2) of the door (1) or to the door (1); at least one elastic flexible element (11) which performs, due to its configuration, an elastic function when it is subjected to bending; fixing means (12) by which said at least one elastic flexible element (11) is fixed to said second fixing element (6); and engaging means (14) by which said at least one elastic flexible element (11) remains engaged to said first fixing element (5) during the relative motion between said first (5) and said second fixing element (6), which is caused by said door (1) moving between said closing position and said maximum opening position and between said maximum opening position and said closing position. In the configuration assumed by the device (4) when the door (1) is at least partially open, said at least one elastic flexible element (11) is subjected to bending and tending to automatically move said door (1) to said closing position.

Included are: a main body including an installation part in which a cartridge housing a liquid for treating a test substance contained in a specimen is installed and a detector configured to detect the test substance treated with the liquid within the cartridge installed in the installation part; a lid part arranged rotatably on the main body about a shaft so as to open and close the installation part; a biasing part biasing the lid part in an opening direction; and a plurality of regulators each generating resistance against a biasing force in the opening direction at different timing during an opening motion of the lid part.

This disclosure is generally directed to a hydraulic door closer, and more specifically is directed to a hydraulic storm or screen door closer that has a fluid overflow chamber providing fluid volume and pressure control for both expanded and contracted fluid at different temperatures. The disclosed hydraulic door closer comprises a fluid overflow chamber adapted to hold sufficient fluid to maintain required operating fluid or oil levels at different temperatures, and to ensure proper closer performance under both extreme high and low temperature conditions.
