    摘要: A connector fitting for interconnecting flexible corrugated conduit sections which includes a pair of arcuate sections joined by flexible straps and having corrugation-engaging ribs which engage the corrugation conduit sections when the arcuate sections of the fitting are closed about the conduit sections. In the closed position, the two arcuate conduit sections are interlocked by means of tongues carried on each of the arcuate sections, which tongues engage a slot carried on the other of the arcuate sections.

    摘要: A connector fitting by which corrugated conduit can be quickly connected to an electrical box. The fitting includes a pair of hingedly interconnected semi-cylindrical collars. Two spaced, box engaging projections are carried on, and extend axially from each of the semi-cylindrical collars, and the inner side of each semi-cylindrical collar is grooved to mate with and engage corrugations carried exteriorly on a corrugated conduit to be connected to an electrical box by the use of the fitting. Each of the box engaging projections includes a wedge shaped free end portion and a web portion by which the wedge shaped free end portion is connected to one of the respective collars. Each wedge-shaped end portion, its associated web portion and the collar to which the web portion is connected define an arcuate channel or relief for receiving and engaging the portion of the wall of an electrical box which surrounds an opening into which the connector fitting is snapped.

    摘要: A die construction for forming integral hinges (60) for a blow molded carrying case. An edge of the main cavity of a lower die (12) of a blow molding die pair is provided at one peripheral wall portion (40) with sloping channels (38). A core pin (32) extends across and spans the sloping channels. The upper die (10) is provided at one peripheral portion with semi-cylindrical recesses (22) coaxial with the core pin and of the same length as the width of the sloping channel. A heated parison (46, 48) is placed (FIG. 1) between the two dies. With die closing and with the introduction of pressurized air (52) into the parison, the parison is deformed. At the same time, the pressurized air also causes one of the plastic parison sheets (46) of the parison to deform into the semi-cylindrical recess, and the other parison sheet (48) to deform into the sloping channel and also around the core pin. The two parison sheets fuse together around the core pin upon complete closing of the two dies (FIG. 3) to form a hinge boss (60) integral with the remainder of the parison sheets which form a carrying case half. The core pin (32) is then removed, to form a hinge pin recess through the hinge boss. Any number of such hinge bosses may be formed, with a single core pin spanning each sloping channel and each semi cylindrical recess. This construction and method obviates the need to subsequently drill hinge pin receiving holes (61) through the hinge bosses (60).
