Abstract
1,022,408. Hinges and pivots. AKUSTISCHE U. KINO-GERATE G.m.b.H. Dec. 12, 1963 [Jan. 2, 1963], No. 49199/63. Heading E2F. [Also in Divisions F4 and H4] An articulated joint for microphones, lighting fixtures or pictures comprises two parallel-spaced leaf springs 1, 2 flexible in one plane, and to the upper ends of which is screw connected or clamped the article or an article-holder, felt brake shoes engaging either both the springs, or one spring, with the other spring mechanically held at its lower end. The joint is such that on deflection of the springs and movement of one or both relative to the felt brake shoes, the joint is frictionally returned in the deflected position. In one embodiment, Fig. 1, a microphone 3 is carried by the springs 1, 2 engaging 1t brake shoes 4, 5, and the springs 1, 2 are formed with noses 7, 6 which engage projection on a housing (not shown) of the joint to limi upward movement of the springs; alternatively a longitudinal slot (not shown) may be provided in the springs for engagement by a screw in the housing. The felt brake shoes may be adjustable. Current may be supplied through the springs via contact rollers or brushes. In another embodiment, Fig. 2 (not shown), the springs 1, 2 and the brake shoes 8 are held together elastically by an encircling tube 9 of rubber or plastic. The spring 1 is fixed at 10 in the housing (not shown) of the joint. In Fig. 3 (not shown), the joint comprises a rubber or plastic I-section member 12, the flanges of the I covering the gap between the springs 1, 2 and the web of the I being grooved longitudinally on each side at 14 to receive the felt brake shoes. The springs are disposed in further grooves in the flanges. Ducts 15 for electric leads, e.g. microphone cables, extend longitudinally through the joint. In another embodiment, Figs. 4, 5 (not shown) the joint is assembled with a control device for a microphone to form a control box 17 fixed to a stand 19. The leaf springs have no fixing means or stops so that the springs may be pulled out from the brake shoes, and guide slots are provided in the box or the lower ends of the leaf springs may be given an oblique or rounded edge.
