Latching motion transfer arrangements may be used to raise an object up and out of the engagement with the ground or other support surface and to lower the object back onto the ground or other support surface. In one exemplary embodiment, the mechanism is caused to lift and latch by applying force in a first direction, a first time, and is caused to release and lower by applying force in the first direction, a second time.

A stroller has a stroller frame with a child seat positioned on the stroller frame. The stroller further includes a child barrier that can be coupled to the stroller frame forward of a seat bight of the child seat. The child barrier also includes a cup holder with a central longitudinal axis. When the child barrier moves relative to the stroller frame, the cup holder pivots about the central longitudinal axis.

A flexible sign board for blade signs is provided. The sign board has a frame with a mounting bracket that is connected to a resilient support. The resilient support is a plurality of springs connected to a shelf or the wall bracket according to the desired application. The springs support and maintain the sign frame perpendicular to the wall or shelf it the sign is attached to and thereby provides a "swing away" effect of the sign when bumped into or pushed out of the consumers way. The flexible sign frame and mounting thereof will not obstruct the consumer aisle, and thereby enables the increased visibility of the displayed items from a further distance. The Flexible sign board system provides the ability to adapt the sign board to an infinite variety of varying shelf depths without using or taking away valuable retail shelf space.

The invention relates to a manually operated fixing clip for joining together removably and so that they can pivot two elements one of which carries the clip and the other a rod forming a pivot pin. The clip has a flexible lip forming, together with another lip, an elastic pinching slit for the entrance of the rod into a housing. A movable bar connected to the clip by elastic tags is placed between two lips either to move them apart sufficiently to allow the rod to leave, or to block the flexible lip in order to prevent the rod from leaving, depending on the embodiment.

A knee hinge with selectively limited motion which optionally limits an available flexion range of a user's knee to approximately 24 degrees so that a user will not fall should the user buckle at the knees. The hinge may be released to provide for a greater range of knee flexion which will allow a user to sit down in a conventional manner. The approximately 24 degree limit of the flexion range is automatically re-engaged when the user's knee is straightened. The hinge provides a spring mechanism for assisting weak knee muscles. The hinge also allows a small degree of knee hyperextension for the purpose of allowing the user to assume and maintain a safe standing position.

A working cylinder which operates without a piston rod, comprising a cylinder tube, a piston which is displaceable therein and is provided with a pulling means, and a force transmission element which is connected with the pulling means and guided in axial displacement on the cylinder tube. In order to minimize the mounting work for the external attachment of the pulling means and at the same time increase the dependability of operation, the pulling means (1) is provided on the ends thereof connected to the force transmission element (2) with clamping pieces (3) which are provided with a toothed surface (5) on at least one outer side (4) and the force transmission element (2) is provided with a correspondingly toothed surface (6) against which the side (4) of the corresponding clamping piece (3) having the toothed surface (5) can be pressed via a pressing element (7). The corresponding toothed surface of the force transmission element (2) is longer than the clamping pieces (3) to allow for adjustment. The pressing element (7) and the force transmission element (2) together form an integral structure.

A light fixture collapsible for shipping has rotatable and axially-displaceable arms that are resiliently urged toward a central body such that when the arms are re-aligned with the body upon unpacking the fixture, the resilient means urges a positioning pin to lock the arm in place. The fixture has a hollow body with a peripheral wall against which a plurality of arms are to extend radially outward. A post on one of the arm and the body extends into the other of the arm and the body, making the arms rotatable about their axes. A positioning pin on the arm and a hole in the body, or vice versa, engage when the arm is in alignment. A helical spring urges the arm toward the body.

The device for fixing an object by screwing to a section having two flanges directed substantially towards one another and defining therebetween a longitudinal opening comprises an elongated plate provided with one of the threaded portions and rotatable in a plane substantially parallel to that of the flanges of the section. In a free position, the longitudinal direction of the plate corresponds substantially to that of the section. In a retained position, the plate is retained under the flanges of the section and immobilized in one at least of the directions of rotation. Resilient means are provided for urging the plate towards the flanges of section in the retained position. The resilient means bear on a wedge intended to be inserted between the external face of the flanges of the section and the object to be fixed. This wedge has a passageway for a connecting rod between the plate and the other screw fixing element.
