Abstract: A shock absorbent bulbholder mounting assembly including a yoke support and a bulbholder interconnected by a pair of spring mounted subassemblies. Each of the subassemblies includes an elongated arm strap adjustably attached to rotate with respect to a respective arm section of the yoke support, and an elongated bulbholder strap attached to a respective side member extending from opposing sides of the bulbholder. The arm strap and the bulbholder strap are disposed in spaced parallel planes. The longitudinal axes of the straps are oriented at right angles to one another, and each end of each strap is connected by two springs to opposite ends of the other strap.

Abstract: The foot bearing the seat surface of a seat is divided at a distance of 20-30 cm from the seat surface. Between the mutually facing end faces of the two foot parts (5a,5b) a rubber cushion (9) is arranged, the circumferential area of which is widened to form a brake ring (11). The elastic restoring force, working counter to the inclination of the seat, of this cushion is reinforced by two further cushions (16,17) arranged within the foot parts (5a,5b). By means of the suitable arrangement of sliding elements with low friction (T1-T3), the mutual rotation between the two foot parts (5a,5b) is ensured.Thanks to this construction, the seat surface can be swiveled in a tumbling manner in such a way that every point of said seat surface moves on an imaginary spherical surface and thanks to the mentioned elastic restoring force, the seat part always returns automatically to its initial position.

Abstract: A construction or emergency sign with a changeable message on its front surface. The sign has a diamond shape or a square shape and one or more flaps are secured along the central diagonal of the sign. The flaps are adapted to be releasably fastened to either of two opposite corners of the sign and have messages on both sides. When the flaps are secured in one corner, a first message is presented and when the flaps are secured in the other corner, a second message is presented. A pair of cross-braces hold the sign in a taut planar configuration. The sign is also adapted to be collapsed into a small, compact package for transport and storage. One embodiment of the sign has two or more flaps thus allowing three or more different messages to be presented. Another embodiment has an additional cross-brace allowing the sign to be used to present either diamond or square-shaped messages.
