Abstract
994,020. Door operating appliances. SOC. DES APPLICATIONS TECHNIQUES DU CAOUTHOUC S.A. T.E.C. April 24, 1964 [April 26, 1963], No. 17106/64. Heading E2M. The invention relates to the use of a pneumatic jack to complete the opening of a door e.g. trap or swing door, after an initial push on the door, the door being returned to the closed position by torsion springs in the hinges, any new opening force applied during this closing movement causing the door to re-open to the fully open position. The device consists of a jack 4 pivotally attached at 3 to the door frame above the door by a bracket 1 and to the door by coupling 6, the door being supported by spring hinges 8, 9 biased to the closed position, in which the pivot points 3, 6, 8 are on the same straight line. After displacement from this position e.g. angle a Fig. 3 the pneumatic ram will complete the opening movement. The jack 4 has a piston rod 5 having a section 33 of reduced diameter near the piston 32, and a sleeve 10 mounted on the piston rod, the frictional engagement of this sleeve on the rod being adjusted by screws 11, and the sleeve abutting a shaped push rod 18 acting against a ball 16 of a ball valve. Initial opening movement of the door causes the piston rod 5 to move (to the right in Fig. 5) taking the sleeve 10 with it and consequently causing the push rod 18 to open the ball valve 16, which allows compressed air from pipe 28 to traverse bore 21, enter opening 22 and act behind the piston via pipe 29. At the fully open position the system is arranged such that the sleeve 10 coincides with section 33, thus releasing its grip on the rod 5 and allowing the spring 17 to close ball valve 16 so shutting off the air supply and returning, via the push rod 18, the sleeve 10 to a position against an abutment 34. The spring hinges then return the door to its close position, air being released via path 29, 22 opening 23, which has been uncovered by the return of the push rod 18, needle valve 24, which controls the speed of closing of the door, the air eventually exhausting through apertures 25, 27.
