Abstract: The connector device of the arched poles of a tent is remarkable in that it includes two components (4-5), (9-10) which are able to be coupled into each other in a configuration and connection in the form of a knee permitting a positioning of said components either in a vertical plane or in an extension corresponding to the assembly and placing under tension of the segments of an arch, or by being folded corresponding to a folded position of said segments, and in that a male component (4-9) has on either side of its median portion a part receiving the end of the upper segment and opposite an arm of great length equipped with means permitting its articulation on the second component (5-10) and its locking into position, and in that a female component (5-10) has on either side of a median portion on the one hand means permitting the attachment of a lower segment, and on the other a fork shape (5b-10d) having a V configuration with inside an oblong port having a V configuration and permitting the positioning, th

Abstract: An operating mechanism of a three-position switch having a contact-bearing main shaft comprises a switch closing and opening operation device, and an earthing device closing and opening operating device. The two devices comprise driving flange plates connected by a common spring capable of being loaded by rotation of either of the operating shafts and transmitting, after the deadpoint has been reached, a drive movement of these flange plates transmitted by articulated levers to a crank handle wedged onto the main shaft. All the operations are high-speed and the torque transmitted to the main shaft increases in the course of the operating movement. A locking device maintains the main shaft in the open position during the loading phase of the spring.

Abstract: An operating mechanism of a three-position switch comprises a tumbler device with an energy storage spring associated with a toggle, a main operating crank controlled by a switching shaft, and an earthing crank mounted in rotation on a first operating spindle. Opening and closing are performed by means of a second operating spindle, offset from the operating shaft and operating in conjunction with a transmission system designed to drive the toggle. A latching lever of the main crank is unlocked by a boss when the toggle is in the vicinity of the dead-point.
