Abstract:
The counterweight means (50; 50') for a motor or manually-operated sectional gate has a traction mechanism (51; 51') which engages, preferably at the bottom, at one end on a closing member, and at the other end indirectly or directly on an energy accumulator or on a mechanical drive such as a counterweight in such a manner that it is possible to insert the lower closing member (5A) into the horizontal section (7B). The counterweight means (50') also has coupling means such that the traction mechanism (51') engages at one end on a driving part (71) and at the other end indirectly or directly on the energy accumulator or the mechanical drive. A driver (74) which can be automatically disengaged from the driving part (71) when a closing member is not completely open and can be re-engaged therewith during closing is fastened to the closing member. Alternatively, the counterweight means (50) has a deflection pulley (54) for the traction mechanism (51), which pulley is arranged to be stationary close to the upper end of the curved section (7C) and substantially below the horizontal section (7B), with the result that the counterweight means (50) exerts a traction force acting substantially horizontally on the lower closing member (5A) which is substantially in the closed position and a traction force acting substantially vertically by means of the traction mechanism (51) on the lower closing member (5A) which is substantially in the closed position.
Abstract:
A sectional overhead door is disclosed with a door leaf comprising several consecutive hinging panels (10, 10´, 10´´) which are guided in the known way by rollers (11) in horizontal tracks and in tracks (12, 12', 12') joined to them to form a bow and are provided with a balancing device (15) in the form of approximately horizontal helical tension springs. The latter are designed to be space-saving, in particular with low drop heights, underneath the horizontal track sections extending into the building, such that on each of the outer side regions (27) of the horizontal track sections (12, 14) facing away from one another one or more helical tension spring units (16) are arranged approximately parallel to one another and one below the other. At least some of the helical tension spring units (16) consist of at least two coaxial helical springs (17, 18), the turns of which are mutually opposing and intersecting.
Abstract:
Torkonstruktion (10), umfassend einen von einer Torflügelführung (12) geführten Torflügel (14), wobei der Torflügel (14) derart ausgebildet ist, dass er mittels eines Seilzuges (16) in eine geöffnete Stellung beaufschlagt wird, dadurch gekennzeichnet, dass der Seilzug (16) flaschenzugartig angeordnet ist und eine Druckbeaufschlagung des Torflügels (14) in Öffnungsrichtung mittels einer an dem Seilzug (16) angeordneten Gasdruckfeder (18) erwirkt wird, wobei eine Bewegung des Torflügels (14) in Öffnungsrichtung eine Federbewegung der Gasdruckfeder (18) erzeugt, deren Betrag kleiner ist als der Betrag der Torflügelbewegung.

Abstract:
A system (1) is disclosed for detecting and signalling in air a failure of balancing systems for closing members comprising at least one local system (3) for detecting a failure of at least one of the balancing systems, equipped with means for transmitting in air at least one failure signal (4) representing the failure of the balancing system; and at least one remote system (5) for receiving the failure signals (4) equipped with means for displaying an alarm indication of such balancing system failure. A remote signalling process which uses the system (1) is further disclosed.
Abstract:
A closing mechanism of a door (2) of a sterilization apparatus chamber (1), which weight is compensated by a spring comprising a spring (3) fixed in a suspender (9) of the spring on one side and in a suspender (16) of a pulley (4) on the opposite side, and a system of a first wheel (5) and a second wheel (6) being fixed in the first and the second suspenders of the wheels while the door (2) of the chamber is connected with suspension chains (7) being guided through a system of the wheels (5 and 6) and the pulley (4) and fixed in a suspension (8) of suspension chains.
