Cross arm for sealing a cubicle with divided doors - uses U=bar with legs projecting inwards with pivot aligned to door pivots, internal support bracket and spring

摘要

A cross arm for sealing a switching cubicle that has divided externally-hinged doors takes the form of a U-bar with legs projecting into the cubicle. It is pivoted between the vertical rails of the cubicle and has a spring on at least one side. The pivot of the cross arm is aligned with the pivot of the cubicle doors. To support the cross arm, a bracket on the inside has a pivot at one end and is attached to the cross arm by a peg sliding in a slot. The bracket pivot point has an eccentric. ADVANTAGE - Allows access to cubicle interior without need for dismantling.
