The present invention is a positioning mechanism device to prevent the motion of one surface with respect to a second surface, in one direction. The positioning mechanism uses a linear adjusting lock, an actuator, and an over-ride mechanism. The linear adjusting lock uses a coil spring to hold a rod in place. When firmly coiled, the coil spring is able to grip a smooth rod and prevent axial motion. When the coil spring is uncoiled, slightly, it releases its grip on the smooth rod, allowing axial motion. The positioner mechanism uses an actuator and release blade to release the coil spring. Additionally, the over-ride mechanism can be used to release the release blade in one direction without use of the actuator. When the coil spring is released by either the actuator or over-ride mechanism the two surfaces can be re-positioned relative to one another.

A fixing device for fixing a second component part at a stationary first component part to be swivelable around a swiveling axis 2 having a cylinder that is displaceable transverse to the swiveling axis and filled with a fluid, a piston displaceably guided in the cylinder that divides the interior of the cylinder into a first working chamber and a second working chamber, with a first valve device that connects the first working chamber to the second working chamber when pressure in the first working chamber is higher than the pressure in the second working chamber, and a second valve device that connects the second working chamber to the first working chamber when pressure in the second working chamber is higher than the pressure in the first working chamber.

A door opening degree adjustment device includes a check link having a stopper portion, a guide member having a guide hole, and an adjustment member. The adjustment member includes a plurality of stages of step portions and a guide projection that is inserted in the guide hole movably in the extending direction of the guide hole. The adjustment member causes the stopper portion to contact the step portions of any one of the stages, thereby restricting an opening operation caused by pivoting of the door in one direction. The guide projection is arranged on an extended line that connects the stopper portion to one of the stages of the step portions that contacts the stopper portion in the direction of the movement of the check link.

A lid stay for a transport container. The lid stay has at least one bearing unit, at least one guide unit and at least one swivel bracket. The lid stay can be moved at least between a locking position and a transport position. Furthermore, the guide unit has at least one latching element. In the locking position, the swivel bracket interacts with the latching element in such a way that the lid stay is held in the locking position. The latching element causes at least a temporary elastic deformation of the swivel bracket when the lid stay is moved between the locking position and the transport position.
