摘要:
Armature de parapluie constituée d'éléments (1) se présentant sous forme d'une pièce monobloc, moulée, comportant plusieurs parties correspondant au bras tendeur (2), à la baleine (3) et à une portion longitudinale (4) du manche. Les différentes parties sont reliées entre elles par des articulations formées par des languettes souples obtenues lors du moulage. Les extrémités des baleines comportent, venus de moulage, des moyens de fixation (18) de la toile. La bague est obtenue à partir d'une pièce moulée plane comportant à ses extrémités des moyens de verrouillage.
摘要:
An umbrella assembly (100) is provided that comprises an umbrella hub (116) comprising an upper portion (142), a lower portion (146) and a passage configured to be disposed about an umbrella pole. The upper portion (142) includes a top surface that extends between the passage and an outer periphery of the hub. The lower portion (146) includes a bottom surface that extends between the passage and the outer periphery of the hub. The umbrella hub (116) also includes a first engagement position and a second engagement position. The first engagement position is configured to permit insertion of end portions of umbrella structural members into the hub. The first engagement position is provided by first relative movement of the upper and lower portions of the hub along an axis extending through the passage. The second engagement position is configured to retain end portions of umbrella structural members within the hub. The second engagement position is provided by second relative movement of the upper and lower portions of the hub along an axis extending through the passage.

An integrated piezoelectric/electrostrictive film type element with excellent durability, includes a substrate (1) made of a ceramic material composed mainly of completely stabilized or partially stabilized zirconium oxide, and a piezoelectric/electrostrictive operating section (5) integrated onto the ceramic substrate by a film-forming method, the piezoelectric/electrostrictive operating section comprising a lower electrode (2), a piezoelectric/electrostrictive layer (3) of a lead element-containing composition, and an upper electrode (4), wherein a heterophase-occurence rate at a surface of the piezoelectric/electrostrictive layer is controlled to a range of 0.1 to 30% by adjusting the atmosphere during sintering.
摘要:
Illuminators include transparent light emitting members (1) having a pattern of rounded shallow notches or grooves (3) in one or more surfaces of the members (1) for causing internally reflected light (5) to be emitted from the members (1). The notches or grooves (3) may be cut using a circular cutting tool. The relative speed of the cutting tool and feed rate of the cutting tool relative to the members (1) may be controlled to produce a roughened surface on the notches or grooves (3).

摘要:
A quick connect system is provided for a shade structure. The system includes a hub and a structural member. The hub has a top surface, a plurality of side walls forming a slot therebetween, and a displaceable retention device having a free end disposed at an elevation below the top surface. The displaceable retention device is moveable laterally away from the slot. The structural member has an end configured to swing in the slot. The end has a laterally extending rotation device. The rotation device extends laterally beyond the free end of the displaceable retention device when the end is disposed in the slot.
