Definitions

  • the counterpoised door is a well-known type, especially used for garages, the lower end being guided in 'relation to the fixed frame round the aperture for the door.
  • Such doors are articulated at their sides by supporting rocker levers coupled to the top of the frame.
  • balancing traction springs are articulated uppermost to the top of the frame, and below, by suitable means, to the sides of the counterpoised door occupying a position appreciably lower than those at which the rocker levers articulate.
  • Subject of the invention is a counterpoised door, used es_ pecially for garages, each of the balancing traction springs being coupled at its lower end to the extremity of an arm on the side of the door so that said arm, due to the effect produced by a strut one end of which is articulated at an intermediate point along the arm and the other at a point low down on the side of the door, projects to some consider able extent beyond the internal plane of the door causing said door to attain an optimum state of balance.
  • the traction springs on each side are coupled to the extre ⁇ mity of the arm by a flexible tying means.
  • Said guide lever is rectilinear but terminates in an arc of practically 90° .
  • the arm fixed to each of the sides of the door articulates at the top in the same axis as that of the lower articula ⁇ tion of the rocker levers and is rendered stable by means of a strut articulated through a slot at its lower end onto a'locking pin in the side of the door and, at its upper end, about halfway along said arm. Therefore, by moving the strut upwards till it reaches the top of the slot, the arm will make its maximum projection.
  • both strut and arm can be made to coincide substantially within the width of the side of the door thus occupying a minimum space.
  • a pin is placed perpendicularly on said strut at an inter ⁇ mediate point between the slot and the upper articulation of the strut.
  • the frame round the aperture is made so that its constant horizontal cross section is similar to an "L” in shape.
  • the long side of the "L” lies parallel to the plane of the door and towards the inside of the garage, while the short side of the "L” lies on the opposite side in relation to the door and is shaped like a "C”.
  • the door arm is articulated on the rocker lever at a short distance from the point where said lever articulates on the side of the door.
  • the first section of the arm lies, in relation to the se ⁇ cond section, between the strut articulation and the trac ⁇ tion spring coupling, at an angle with its vertex inwards, said angle being almost the same as the angle made by the first section of the arm with the strut when the door is closed.
  • the spring is coupled to the arm of the door by means of a threaded rod whose position, in relation to said spring, etui be adjusted by a pair of nuts or by some similar means.
  • the angle between the two sections of the arm, the size of the arm and of the strut, and their positions are such that when the rocker lever is made to align with the spring, pra tically the whole coupling and balancing device automati- cally stows itself away inside the thickness of the door thus offering appreciable advantages for storage and tran ⁇ sport.
  • the guide lever (22) with its curved extremity (23) also revolves on said articulation.
  • the perpendicular pin(25) is fitted onto the strut.
  • the upright of the frame (26) has an L-shaped cross sec- tion (Fig.3) with a long side (31) and a short side (27) curved to form a "C".
  • FIG. 2 shows the position of the strut (17) when the pin (15) is at the upper end of the slot (16). In that position all the parts: spring (18), tie (20),arm (14) and strut (17) fit into the thickness of the door.
  • Fig. 3 clearly shows how the bearing (29) slides smoothly inside the upright of the frame (26) and also the sliding movement of the bushing (30) against the C-shaped part of said frame.
  • Example 2 The lower articulation (42) of the rocker lever (43) is situated in the side (41) of the door (40) .
  • the arm (44) is articulated on said lever in the pin (47).
  • the balancing spring (50) is held to the cross bar (51) of the frame by an upper coupling (60), and below to the pin (48) of the extremity (46) of the arm by means of a tie rod (52) with threading (53) and lock nuts (54), (55).
  • the strut (56) connects the intermediate section of the arm to the side of the door by means of articulations (58) and (57) respectively, creating the two sections of the arm (45), (46).
  • the extremity (46) of the arm (44) is set at an angle, in relation to the first section (45), almost equivalent to the angle made by the strut in relation to said section (45) when the door is being closed.
  • the distance X between articulation (47) of the arm on the rocker lever (43) and articulation (57) of the strut on the side of the door is the greater dis ⁇ tance and therefore the angle between section (45) of the arm and that of the strut is the minimum angle, and si- milarly minimum is projection of the arm.
  • Balancing can .be regulated according to specific instal ⁇ lation characteristics and to those of the door itself.
  • the door slides easily on its frame and offers a high de ⁇ gree of guarantee against accidental displacement.

Abstract

Une porte à contrepoids (10, 40) pour garages comprend des ressorts de traction équilibrants (18, 50) s'articulant vers le bas sur un bras (14, 44) fixé sur le côté (11 ,41) de la porte (10, 40) et tourné vers l'intérieur. En raison de l'effet produit par une entretoise (17, 57) s'articulant à l'une de ses extrémités en un point intermédiaire situé le long du bras (14, 44) et à son autre extrémité en un point plus bas situé sur le côté (11, 41), ledit bras s'étend en position de fonctionnement considérablement vers l'extérieur par rapport au plan interne de la porte (10, 40), assure un équilibrage optimal de ladite porte et, pour des raisons de transport, tient presque entièrement dans l'épaisseur de ladite porte (10, 40).
