Definitions

  • the invention relates to a torsion spring device for counterbalancing the weight of a building closure, such as gates - in particular a ceiling sectional door, roller door, lifting gate - which is moved up and down with respect to a movement component, the displacement movement of which is translated into the rotation of a shaft which runs approximately coaxially with the spring device and with which one Rotational movement is applied to the one end of the other end of the stationary spring device in such a way that it tensions in a force-storing manner when moving downward and releases the stored force when moving upward.
  • a torsion spring device for counterbalancing the weight of a building closure, such as gates - in particular a ceiling sectional door, roller door, lifting gate - which is moved up and down with respect to a movement component, the displacement movement of which is translated into the rotation of a shaft which runs approximately coaxially with the spring device and with which one Rotational movement is applied to the one end of the other end of the stationary spring device in such a way that it tensions in a force-storing manner when
  • such torsion spring devices consist of one or more torsion springs arranged axially distributed along a shaft, which are coaxially penetrated by the shaft and, because of their limited number, namely one to three, must each be individually designed to be “hard”, ie they each consist of a thick, coarse spring wire and are correspondingly large in volume.
  • These torsion springs which require correspondingly large spring cones to hold their ends, are difficult to tension and therefore have to be adjusted on site.
  • the invention has for its object to provide a torsion spring device for weight compensation of the type in question, which is easier to manufacture and less at risk of spring coil breakage.
  • this object is achieved according to the invention in that a plurality of individual torsion springs are arranged around the shaft axis outside or inside the shaft (hollow shaft) on its inner casing wall over the circumference of the shaft, one end face end (6) of which is arranged over a shaft Gear device (8) transmitting force in the same direction and the other ends (7) of the end face are rigidly combined with regard to the force-transmitting action.
  • the torsion spring device is therefore characterized in that instead of a large-volume individual torsion spring which is arranged around the shaft, a plurality of individual torsion springs are provided, which are arranged distributed around the shaft with regard to their attachment options and preferably run parallel to one another with regard to their longitudinal axes are arranged.
  • One end of these individual springs is rigid and the other ends are connected to the shaft via a geared connection, which accompanies the door leaf of whatever kind with regard to its rotation.
  • the individual springs which can be arranged interchangeably or exchangeably, can have different force-travel characteristics, and thus the spring device as a whole can be better determined with regard to its weight-balancing effect.
  • the gear connection which collects the forces of the connected individual springs, is designed as a planetary gear, the individual springs being connected at one end to a planet gear, which planet gears work on a common central gear serving as a collecting member.
  • 1 shows a torsion spring device which engages a shaft 2, which is connected to the door leaf in such a way that the closing and opening movement converts into a rotational movement of the shaft 2, for example in that in a manner not shown
  • the two ends of the shaft are provided with cable drums which receive cables which engage with their free ends on the lower edges of a door leaf.
  • Such gate constructions are known in a variety of designs.
  • the torsion spring device 1 is formed from a multiplicity of individual torsion springs 3, which are arranged around the shaft 2 and run parallel to this and to one another with respect to their longitudinal extent. Each of the individual springs 3 is penetrated by a spring support axis 27 and positioned by supports 4 and 5, respectively.
  • the right-hand ends 7 of the individual springs 3 are connected to one another in a "rigid" manner, i.e. they cannot rotate about their respectively associated axis 27, while the left-hand, gear-side end 6 of each of these individual springs 3 is connected in a rotationally fixed manner to a planet gear via a holding cone 14.
  • the other end face is fixed rigidly via a holding cone 13, which is at the same time designed to tension the spring (pretension).
  • the gear device 8 for the gear coupling of the gear-side end faces 6 of the individual springs 3 to the shaft 2 is made with the aid of a planetary gear which consists of an externally toothed central gear 9 and one of the number of individual springs 3 - as can be seen from FIG. 2, for example four - combs the corresponding number of planet gears 10, each of which is connected in a rotationally fixed manner to a gear-side end 6 of a single spring 3 via a retaining cone 14.
  • the shaft holder 4 are held stationary, so that the "rigid" ends 7 of the individual springs are rotatable and fixed overall.
  • a rotation of the shaft 2 caused by the door leaf (not shown) is transmitted via the central wheel 9 to the planet gears 10 in such a way that the springs 3 are tensioned when the door leaf moves in the closing direction. This compensates for the torque that increases on shaft 2 in the course of the closing movement.
  • the force stored in the springs 3 supports the upward movement of the door leaf via the planetary gear 8 in the reverse flow of force.
  • Figure 3 works on the same principle as that of Figures 1 and 2.
  • the planetary gear in this second embodiment is one with the Shaft 2 non-rotatably connected, internally toothed central wheel 17 which meshes with planet gears 18, which in turn are non-rotatably connected to the gear-side ends 6 of the associated individual springs 3.
  • the individual springs 3 with their spring mounting axes 27 with their rigidly combined ends 7 on a shaft holder 5 and with their gear-side ends 6 are rotatably mounted in openings of a support disk 15 and connected to planet wheels 10 in a rotationally fixed manner. Both the shaft holder 5 and the support disk 15 are connected to the shaft 2 in a rotationally fixed manner.
  • the shaft holder 5 and the support disk 15 are connected by means of a tube 16 to form a torsion-resistant unit on which the individual springs are held and which act as a "package" on the shaft 2 is attachable.
  • the planet gears 10 which protrude from the gear-side end 6 of the springs and protrude beyond the supporting disk 15 are in engagement with an externally toothed central wheel 9, which in turn is secured against rotation on a stationary holder 19, which in turn is for the centered arrangement of the central wheel 9 comprises the shaft 2 oriented.
  • a rotary movement introduced into the shaft 2 by the door leaf or a drive thus also occurs on the shaft holder 5 and the support disk 15, so that the individual springs held thereon also rotate about the axis of rotation of the shaft 2.
  • the planet wheels 10 roll on the stationary central wheel 9, whereby the individual springs are tensioned in the course of the closing movement of the door leaf and relax accordingly in the course of the opening movement.
  • FIG. 6 works according to the same concept, only a planetary gear is provided in the area of the gear connection 8, which works with an internally toothed central wheel 17, which is fixed against rotation to the holder 19 and meshes with a number of planet wheels 18 corresponding to the number of individual springs .
  • a switch lug 23 protrudes from the signal disk 11 and bears on the actuator of a switch 22.
  • the arrows drawn in FIG. 7 show the rest position of the bolts 20 in the elongated holes 21, the signal disk 11 is rotated by the spring force of the actuator of the switch 22 via the switch nose 23 such that the projections 24 each abut one of the bolts 20. If one of the springs breaks, there is a corresponding reaction force on the bolts 20, which then move along the elongated holes 21 and rotate the signal disk 11 over the associated projection 24, so that the switch 22 is actuated and indicates the breakage of a spring.
  • FIG. 8 shows a spring break monitoring device for a torsion spring device according to FIGS. 4 to 6, in which the end of the individual springs facing away from the planetary gear 8 rotates with the shaft holder 5 and the shaft 2 during operation.
  • bolts 20 connected to the cones 13 pass through corresponding elongated holes 21 in the shaft holder 5 connected in a rotationally fixed manner to the shaft and engage respectively assigned signal pawls 25, so that in the event of spring breakage, the corresponding bolts 20 by reaction force make the signal pawls 25 weak against the force of a correspondingly weak one designed holding spring 29 pivot radially outward by a certain distance.
  • the signal pawl is held under the force of an associated storage spring 28.
  • the Swung out pawl 25 reaches the area of engagement of an actuator of a switch 26 - preferably a snap-in switch - so that if the spring breaks in the course of the next rotary movement, actuation of this switch 26 indicates the spring break.
