Definitions

  • the present invention concerns a spring attachment member for securement of a door balancing spring which is coiled about a shaft.
  • the main purpose of the present invention is prima- rily to provide a spring attachment member which is arranged in such a manner as to allow the door balancing torsional spring/springs to be tensioned upon downwards movements (closing) of the door.
  • a spring attachment member which is characterized in that at least one of the ends of the spring is arranged to be secured to a split two- piece spring attachment member enclosing the spring shaft, one attachment member part being slidable in the lengthwise direction of the shaft as well as being arranged to turn about said shaft, and in that the second, complementary attachment member part is arranged for sliding movement in the lengthwise direction of the shaft but is non-rotationally mounted thereon, said two attachment member parts arranged to be securely interconnecte .
  • FIG. 1 shows a spring attachment member and the associated spring in a disconnected, pre-assembly posi ⁇ tion.
  • Fig. 2 illustrates the spring attachment member in the tightened assembly position
  • Fig. 3 illustrates the attachment member in its fully mounted position, the alternative displaced posi ⁇ tion of the attachment member being shown in broken lines.
  • the subject invention concerns a spring attachment member 1 for a door balancing spring 2 which is coiled about its associated door spring shaft 3, one end 3A of said spring being non-rotationally secured to a cable drum 4 on which drum 4 is wound a cable 5 which is attach- ed to a door.
  • the door is guided for movement along tracks extending alongside the opening to be closed by the door.
  • one end 2A of the spring 2 which preferably is of the helically wound type, is arranged to be attached to a split, two-piece spring attachment member 1 which encloses the spring shaft 3.
  • attachment member 1 1 of the attachment member 1 which part is intended to be attached to the spring 2 and to be positioned next to said spring, is mounted on the shaft 3 in such a manner as to be displaceable along said shaft 3 in the directions indicated by arrows 6, 7.
  • this attachment member part 1 is mounted for rotational movement atbout the shaft 3 in the direction indicated by arrows 8-9.
  • the second complementary attachment part 1 of the two-piece attachment member 1 is mounted on the shaft 3 for movement in the longitudinal directions thereof indicated by arrows 6-7.
  • attachment member part 1 is non-rotationally attached to the shaft 3 and consequently these two components turn together as one single unit.
  • the two attachment member parts are interconnectable, for example by means of non-threaded through-holes 10 formed in e.g. the second attachment member part V and threaded holes 11 formed in the other attachment member part 1-, and by means of threaded attachment bolts 12 arranged to be received in the respective holes 10, 11 so as to form an integrated spring attachment member 1 which is non-rotationally secured to the spring shaft 3 but displaceable in the longitudinal directions 6-7 of the shaft 3.
  • the two attachment member parts 1 , 2 1 are disc-shaped, presenting e.g. a circular circum ⁇ ferential configuration, with the first attachment mem- ber part 1 having a circular central opening to allow free rotational movement of said attachment part in coupling position I around the spring shaft 3 whereas
  • the second attachment member part 1 has a central open ⁇ ing 13 of irregular configuration in order to be turned together with and by said spring shaft 3.
  • the 2 part 1 has a circumferential configuration which essen ⁇ tially matches the shape of the spring shaft 3.
  • the spring shaft 3 may for instance have a non-round config ⁇ - ration or a polygonal circumferential configuration, such as a hexagonal shape, in which case the central opening 13 has a configuration matching that of the spring shaft 3, i.e. the central opening 13 has a con ⁇ gruent hexagonal configuration.
  • the hub portion 14 of the first attachment member part 1 is arranged to receive a bearing means of comple ⁇ mentary configuration projecting in axial direction
  • the second end 2B of the spring 2 may be attached to a similar attachment member to that described in the aforegoing or to a conventional attachment member 15, for instance of the kind illustrated in the drawing figures and comprising a disc-shaped attachment member part 16 to which the spring 2 is secured by means of a screw 17 and which attachment part 16 is arranged for securement in a wall-mounted bracket 18 which by means of screws 19 is fastened to the intended mounting place.
  • Attachment member part 1 of the intended two-piece spring attachment member 1 is formed with reception means 21 designed in conformity with a manually actuable turning element 20.
  • the reception means may be e.g. a number of apertures 21 adapted to receive one end 20A of a lever 20.
  • a plurality of lever receiv ⁇ ing apertures 21 are distributed along the circumference ⁇ of the associated attachment member part 1 .

Abstract

L'invention concerne un élément (1) de fixation de ressort, destiné à fixer un ressort (2) d'équilibrage de porte, lequel est enroulé autour d'une tige (3). Selon l'invention, au moins une (2A) des extrémités du ressort (2) est agencée pour être fixée à une fixation (1) à deux pièces renfermant la tige (3) de montage du ressort. Une partie (11) de l'élément de fixation coulisse dans le sens longitudinal (6-7), et est agencé pour tourner (8-9) autour de ladite tige (3). La seconde partie (12) de l'élément de fixation complémentaire est agencée pour effectuer un mouvement de glissement dans le sens longitudinal (6-7) de ladite tige (3), mais n'est pas montée rotative sur cette dernière. Les deux parties (11, 12) de l'élément de fixation sont agencées pour être interconnectées solidement.
