Definitions

  • the invention relates to a cam mechanism based on a door closer.
  • Door closers with cam mechanism typically have a Hubkurvenin rotatably mounted on an output shaft, which has a drainage surface on which a pressure roller unrolled pressed due to a closing spring.
  • the Hubkurvention seen in the direction of a longitudinal extension of the output shaft of the door closer may have a symmetrical or asymmetrical cross-sectional shape.
  • the pressure roller is mounted so that it can move on the Hubkurvenis to and from her. The movement takes place in the direction of the axis of rotation of the output shaft and away from it.
  • the torque curve is determined by the shape of the respective running surface of the Hubkurvenin. This means that the Hubkurvenin must be specially designed for each application, ie constructed.
  • asymmetric cam discs have been developed whose two drainage surface halves are designed for one operating mode.
  • the course of the respective torque curve defined by the shape of the run-off surfaces can not be changed.
  • DE 27 55 787 shows a door closer with the features of the preamble of claim 1.
  • Further generic door closers are eg off DE 29 38 445 or DE 19 506 220 known. If now a door provided with a door closer door are provided with a fire protection function, are in a predetermined first opening angle range (about 0 ° - 4 °) of a rotary wing and in a predetermined second opening angle range (about 88 ° - 92 °) of the rotary vane torques permitted only within predetermined limits. In addition, there is a minimum torque that must not be exceeded over the entire opening angle range of the rotary wing.
  • the object of the invention is to provide a door closer, which can be manufactured inexpensively adapted to the particular application or even adapted or converted in the assembled state to the particular application.
  • FIGS. 2B, 2C . 7D-7F . 10 and 11 embodiments shown are essential to the invention.
  • the embodiments shown in the other figures are merely examples, which are not attributable to the subject of the claim.
  • a door closer has a pressure roller, which rolls pressed against a cam disc of the door closer.
  • the Hubkurvenin is arranged rotatably on an output shaft.
  • the pressure roller is arranged with respect to an axial center of the output shaft so that the pressure roller moves along a path when opening or closing a coupled to the output shaft rotary vane becomes.
  • the torque curve is a characteristic of a voltage applied to the output shaft of the door closer torque in dependence on the opening angle of the rotary wing.
  • the advantage is that not only is the torque variable in proportion, but it is also possible to change the shape of the torque curve during a movement, i. H. a closing movement of a rotary wing, despite using a Hubkurvenectomy with one and the same shape to adapt to the particular application.
  • these operating modes include slide rail operation and normal or scissors linkage operation, and preferably additionally parallel linkage operation.
  • the described torque curve approximation results in particular in a fall installation of the door closer according to the invention in slide rail operation on a tape opposite side or in normal linkage operation on a hinge side.
  • the same effect results in particular in a door leaf assembly of the door closer according to the invention in slide rail operation on the hinge side or normal rod operation on the hinge opposite side.
  • the door closer is also applicable to both DIN-right and DIN-left swing doors.
  • the housing in the region of the drive shaft ends in each case one Through opening, which is optionally provided by means of a cap, so that the unused end of the output shaft is hidden from the outside.
  • the pressure roller is not fixed with respect to the Hubkurvenin in their position. Ie. during a rotation of the Hubkurvenin this moves the pressure roller to a predetermined position. The position reached then corresponds to the position at which the desired torque curve is achieved. The adjustment takes place with a symmetrical Hubkurvenin with respect to their symmetry axis. This can be done by the pressure roller is arranged displaceably in a direction transversely or at an angle between 0 ° and less than 90 ° to the above-described movement path of the pressure roller.
  • the invention provides, vorzuvercard the Hubkurvenis. This makes it possible to match the torque at an opening angle of 0 ° in the aforementioned modes to each other.
  • the Hubkurvention is symmetrical and preferably has a heart-shaped cross-sectional area. This has cost advantages compared to an asymmetric cam disc. On the one hand, the shape of only one half of the running surface of the Hubkurvenin to calculate and thus construct. Furthermore, fewer different drain surface shapes are required, which reduces the variety of Hubkurvenincilationn to be used and thus to manufacturing tools.
  • the door closer according to the invention is designed so that the direction of the movement path of the pressure roller in the assembled state of the door closer can be adjusted. This makes it possible, the door closer in the assembled state, d. H. on site, still to adapt to any peculiarities of the opening or closing process.
  • this makes it possible to provide the door closer with a new function in retrospect or, for example, switch from slide rail operation to normal linkage or parallel linkage operation or vice versa. Ie. one and the same door closer is universally applicable. The manufacturing costs are reduced because with fewer types of door closers, a variety of automatic functions, such as fire protection function, can be realized.
  • the arrangement consisting of at least one pressure roller and a closing spring rotatable and store lockable, wherein the rotation point is not the axial center of the output shaft of the door closer.
  • the arrangement can be mounted as a whole displaceable.

  • the force transmission ratio i cam At an opening angle ⁇ of 0 ° is the force transmission ratio i cam is substantially equal to 1. Thereafter, the force transmission ratio i cam falls within a relatively small opening angle range relatively steeply to a lower, minimum value and then increases again.
  • a force transmission curve according to the left-hand diagram in FIG Figure 1C , Unlike the in FIG. 1B shown power transmission curve is the force transmission i cam here at an opening angle ⁇ of 0 ° much higher, it may have a value between 3-7 or even tend to near infinity. After that, the force transmission i cam falls off similar to an upwardly open parabola. The negative increase in the power transmission curve is steadily decreasing. The resulting torque curve is right in Figure 1C shown.
  • the torque M is at the beginning, ie at an opening angle ⁇ of 0 °, relatively high and is about 3 - 4 Nm. Thereafter, the torque falls very sharply within a very small opening angle range and approaches a lower, minimum value.
  • the setting of a door rest position opening angle ⁇ in a range of about 0 °
  • Small changes in the opening angle ⁇ cause a large change in the torque M.
  • the pressure roller is movable along a path in which a direction of movement of the pressure roller in each point of the track does not intersect the axial center of the Hubkurvenin.
  • FIG. 1D two diagrams are shown, indicating the torque curves for a cam mechanism with conventionally arranged pressure roller in Gleitschienen- or normal rod operation.
  • the respective upper characteristic curve indicates the torque curve during an opening process
  • the lower characteristic curve shows the torque curve during a closing operation.
  • the differences between these characteristics are due to the fact that the opening takes place against the force of a closing spring.
  • the torque M at an opening angle ⁇ of 0 ° when opening in normal linkage operation is much higher (about 162 Nm) than in slide rail operation (about 111 Nm).
  • closing the torque M is at an opening angle ⁇ of 0 ° in normal linkage operation about 81 Nm and at Gleitschienen-operation about 55 Nm.
  • the differences of the torques M in the two operating modes to each other consequently amount to about 51 Nm or 26 Nm. Furthermore, the torque curve at normal start-up operation falls significantly steeper at the beginning than the torque curve at slide rail operation. The torque curves thus have different gradients.
  • Figure 1E shows torque curves, which are achieved when a pressure roller is arranged according to the invention.
  • the torque M In normal linkage operation, the torque M at an opening angle ⁇ of 0 ° when opening is about 142 Nm and when closing about 70 Nm.
  • the torque M In slide rail operation, the torque M at an opening angle ⁇ of 0 ° when opening is about 143 Nm and when closing about 71 Nm.
  • the differences of the torques M in the two modes of operation are only about 1 Nm, thus in a range between 0.7% and 1.5% with respect to a respective reference torque in one mode.
  • the torque curve in normal rod operation at an opening angle ⁇ of 0 ° does not drop as steep as in Figure 1E , Rather, the shapes of the torque curves, so the torque curves in the two modes are approximated.
  • the torques M in the mentioned modes are identical or very similar at a respective opening angle ⁇ .
  • the difference of the torque values at a respective opening angle ⁇ in the modes of operation is in a range of at most 10%, preferably 5% or less with respect to one of the applied torques in one of the modes.
