Definitions

  • the invention relates to a joint arrangement for actuating a flap, in particular a smoke flap or dome, which can be pivoted about a fixed, first axis of rotation from a closed position into an alarm position and back, with at least one linear drive element, one end of which at a point remote from the axis of rotation the flap is pivotally attached to a cross member of the flap and which, on the other hand, is pivotally attached to a support lever about a first pivot axis, which in turn is pivotable about a fixed, second pivot axis in the vicinity of the pivot axis of the flap.
  • a known joint arrangement of the type mentioned at the outset has a second drive element designed as a cylinder, which on the one hand pivotably engages at one end of the support lever and on the other hand on a bracket which extends downward from the vicinity of the axis of rotation of a dome.
  • the support lever can be pivoted upward, together with the first cylinder, which is also pivotably mounted approximately in the middle of the support lever and which, on the other hand, extends to an upper cross member of the skylight dome.
  • the designation joint arrangement chosen in the application is a synonym, in particular for an RWA device.
  • the joint arrangement can also be used in other devices with a flap actuation.
  • a gas spring for actuating a skylight dome, which engages at the end of a support lever.
  • a third actuating element - motor or cylinder - is required.
  • a stand frame can be opened by approximately 170-180 ° with a pressure medium cylinder which is articulated on a bracket or support lever which is articulated on a curb.
  • a piston rod of the pressure medium cylinder is pivotally connected to the mounting frame.
  • An additional damping cylinder is connected on the one hand to the first common swivel axis between the pressure medium cylinder and the support lever and on the other hand to a fixed cross member of the curb.
  • the support lever serves as a support during the opening stroke of the print media cylinder.
  • the stand frame with skylight dome can roll over into its fully open end position, the complete opening being supported by the kinetic energy which is generated by the extension of the piston rod of the pressure medium cylinder.
  • the rollover movement of the support frame, which begins after the piston rod has been fully extended, is damped with the damping cylinder (DE-A-3 143 318).
  • a compression spring in a tube always tries to press a closure flap into an open position via a piston rod and a first connecting lever and a second connecting lever (US-A-2 544 500). Therefore the opening movement is limited by a chain or a cable.
  • one end of the tube, in which the compression spring is accommodated is articulated on the flap, while the opposite end of the piston rod forms a common first pivot axis with the first connecting lever.
  • the opposite end of the first connecting lever is pivotable about a fixed axis.
  • the second connecting lever is pivotably attached to this.
  • the opposite end of the second connecting lever is in turn hinged to the flap.
  • tension spring In another known arrangement, only a single tension spring is used for positioning doors or the like, in particular for opening (FR-A-1 467 870). Its first end is connected to a fixed swivel axis near the axis of rotation of the door. The opposite end of the tension spring is pivotally attached to a rod about a pivot axis, which can be regarded as a support lever. One end of an additional lever, which can be regarded as a deflection lever, is arranged on the latter pivot axis. A second end of the additional lever or reversing lever is pivotally connected to the door at a distance from its axis of rotation.
  • the fixed pivot axis, about which the tension spring can be pivoted is higher and closer to the first axis of rotation, about which the door can be pivoted, than the pivot axis, about which the rod corresponding to the support lever can be pivoted.
  • a gas spring is pivotally attached at one end to a toggle arm which can be regarded as a support lever (DE-A-2 633 787).
  • the other end of the gas spring is pivotable about a pivot axis in the vicinity of the pivot axis of the flap.
  • a further pivot axis for a second, smaller toggle lever arm In the vicinity of the pivot axis for the gas spring on the toggle lever arm there is a further pivot axis for a second, smaller toggle lever arm, the second end of which is articulated on the flap away from its axis of rotation.
  • the fixed pivot axis, about which one end of the gas spring can be pivoted on a bearing plate, is not further than the pivot axis, about which the toggle lever arm corresponding to the support lever can be pivoted, with respect to the first axis of rotation of the flap.
  • US-A-4,429,491 discloses a joint arrangement with the features of the preamble of claim 3 and FR-A-2,469,543 a joint arrangement similar to this. Both known objects have a drive element, a support lever and a bell crank.
  • the subject of FR-A-2.469.543 has a fixed pivot axis on which the drive element is arranged, but here the drive element does not engage with its other free end on the pivot axis common to the deflection lever and the support lever.
  • the fixed pivot axis for the drive element is not located at a local distance from the axis of rotation of the dome, which is between the distance of the fulcrum for the bellcrank and the fulcrum for the support lever to the axis of rotation of the dome.
  • the object of the present invention is to create a joint arrangement of a device with a flap which can be operated completely independently in and from an alarm position and which can be opened and closed over a large swiveling range, which can be up to approximately 165 °, with only one drive element allowed.
  • joint arrangement of the type mentioned in the preamble of claim 1 in a first variant in that the joint arrangement has only one linear drive element, on the first pivot axis of which an additional deflection lever is pivotably arranged with a first end, the second end End pivotally engages the cross member of the flap at a distance from its axis of rotation and to the attachment point of the first end of the drive element.
  • a completely automatic opening or closing of the flap in the alarm position or out of it is thus achieved with only one additional passive element, namely the bell crank.
  • the positions of the two swiveling axes, the axis of rotation and the fulcrum, which form a four-bar linkage, can be selected when designing the joint arrangement.
  • the first pivot axis, on which the drive element is mounted is located at one end of the support lever.
  • the support lever does not need to protrude bulky beyond the pivot axis.
  • the stated object is achieved for a hinge arrangement of the type mentioned in the preamble of claim 2 in that the hinge arrangement has only one linear drive element which is long in construction, the first pivot axis of which lies approximately in the middle of the longitudinal extent of the support lever that an additional bellcrank is pivotally arranged with a first end at an end of the support lever remote from the second pivot axis, and that a second end of the bellcrank is pivotable on the cross member of the flap at a distance from its axis of rotation and to the attachment point of the first end of the drive element attacks.
  • the second variant is therefore based on the same principle as the first variant, according to which only a single linear drive element for opening and closing the smoke flap or Dome around a large swivel range is sufficient by making use of an additional deflection lever as a passive element which is articulated at a location of this support lever which is remote from the second swivel axis about which the support lever can be pivoted.
  • the bell crank also has the effect here that a longitudinal expansion of the drive element has an effect in lifting and opening the smoke flap and, conversely, shortening the drive element in retracting or closing the smoke flap.
  • the second variant in which the cylinder pivot point is moved approximately to the center of the support lever, is particularly advantageous if a cylinder with a longer stroke is selected, since the cylinder can be extended downward beyond its first pivot axis on the support lever.
  • the cylinder In the closed state of the smoke flap, the cylinder is arranged obliquely so that it does not protrude far down.
  • the lower end of the drive element abuts a cross member on which the flap is pivotally mounted when opening or closing.
  • a third variant is based on a joint arrangement for actuating a flap, in particular a smoke flap or dome, which can be pivoted about a fixed, first axis of rotation from a closed position to an alarm position and back, with at least one linear drive element, one end of which is around a first Pivot axis is pivotally attached to a support lever which in turn is pivotable about a fixed, second pivot axis in the vicinity of the axis of rotation of the flap.
  • the stated object is achieved in that the joint arrangement has only one linear drive element, on the first pivot axis of which there is an additional deflection lever with a first one End is pivotally arranged, the second end pivotally engages the cross member of the flap at a distance from the first axis of rotation, and that the drive element with its second end is pivotable about a fixed, third pivot axis which is in fixed connection with a fixed, second cross member , to the first axis of rotation, about which the flap can be pivoted, is arranged deeper and horizontally further, ie at a greater horizontal distance than the second pivot axis, about which the support lever can be pivoted.
  • the task is solved according to the same principle as in the first two variants, namely with a single linear drive element to achieve a large swivel range and with an additional deflection lever, one end of which is pivotally connected to the support lever and the other end of which Truss part of the smoke flap is articulated.
  • the third variant differs essentially only in a different arrangement and mounting of the linear drive element.
  • the third variant advantageously achieves a large ratio of the torques exerted on the smoke flap when opening to the torques when closing. This advantageously takes into account the greater load when opening, in particular due to snow or ice.
  • the third variant of the joint arrangement takes up more installation space than the first variant, which is therefore cheaper in this regard.
  • the second pivot axis, about which the support lever can be pivoted is preferably attached to a support bracket approximately below the axis of rotation of the flap or its cross member.
  • a double-stroke cylinder is advantageously used as a linear drive element.
  • the first and the second pivot axis can simultaneously serve to supply the compressed air to the lifting cylinder, according to claim 7, the first pivot axis and the second pivot axis each serving as rotary unions for the supply of the pressure medium to which the lifting cylinder is designed. Between the pressure feedthroughs on the first pivot axis and those on the second pivot axis there is a line of the pressure medium which pivots together with the support lever.
  • a locking device can be arranged near the first end of the linear drive element on the cross member such that the locking device can be actuated by the drive element.
  • the drive element has an additional function, namely the automatic actuation of the locking device, which is necessarily synchronized with the opening and closing movement.
  • Fig. 1 the elements of the first variant of the joint arrangement are denoted in the closed representation with simple numbers, the same elements in a normal ventilation position with the same numbers, but with a dash and the same elements in the alarm position with the same numbers, but with two dashes.
  • the hinge arrangement serves to actuate a smoke flap, which is not itself shown, but which is firmly connected to a cross member 1, which extends in the middle of the smoke flap between two opposite sides of this smoke flap.
  • the upper cross member and with it the smoke flap can be rotated about an axis of rotation 2.
  • the turning range is with a dash-dotted circle segment 3 indicated. It extends over about 165 °.
  • the upper cross member lies on a lower cross member 4, from the left side of which a support bracket 5 extends vertically downward.
  • the support bracket is stiffened with a support 6, which is guided obliquely upwards to the cross member 4.
  • a piston rod 8 is articulated to the upper cross member 1 and belongs to a double-stroke cylinder 9 - a compressed air cylinder.
  • the double-stroke cylinder 9 represents a linear, straight-line drive element of the joint arrangement, namely its only one.
  • a lower end 10 of the double-stroke cylinder 9 lies in an imaginary first pivot axis 11, which is designed as a rotary feedthrough for supplying the compressed air to the double-stroke cylinder.
  • the pivot axis or the rotary leadthrough is arranged at one end of a support lever 12, the opposite end of which is mounted on the second end of the support bracket 5 on a second pivot axis 13, which is also realized by a rotary leadthrough.
  • a deflection lever 15 also extends between the first pivot axis 11 and a pivot point 14 in the cross member 1.
  • the deflection lever 15 thus represents a passive connecting element between the first pivot axis 11 and the cross member 1 in addition to the active connecting element, namely the double-stroke cylinder 9, whereby there are different points of attack on the top of the truss.
  • the pivot point 14 is closer to the axis of rotation 2 than the center of the upper cross member.
  • the axis of rotation 2, the first and the second pivot axis 11, 13 and the pivot point 14 form a four-bar linkage.
  • the mutual Distances of the axis of rotation, the two pivot axes and the pivot point can be selected in certain ranges in order to specify the angular velocities of the pivoting movement of the upper cross member 1 and the forces occurring during this movement, which are exerted in particular by the double-stroke cylinder 8 on the upper cross member.
  • the double-stroke cylinder 9 when the double-stroke cylinder 9 is pressurized with compressed air so that the piston rod 8 is pushed out of it, the locking device that allows the upper cross member 1 and the smoke extraction flap connected to it to pivot is released first.
  • the double lifting cylinder 9 is supported on the support lever 12 on the pivot bearing 11, which, however, cannot deflect downwards in a clockwise direction because of the bell crank 15. Rather, the elements connected to the first pivot axis 11 at the bottom are pivoted counterclockwise, which has an effect on the right side 7 of the cross member 4 in FIG. 1 in a pivoting movement in the direction of an arrow 17.
  • the force deflection by means of the deflection lever 15 generates a thrust force in the support lever, which is supported on the support bracket in the region of the second pivot axis 13.
  • the normal ventilation position is reached, in which the upper cross member is denoted by 1 '.
  • the reference symbols of the other elements in the normal ventilation position are also marked with a line.
  • the fully open alarm position is finally reached at approximately 165 °, in which the upper part of the cross member is denoted by 1 ⁇ .
  • the piston rod 8 ⁇ is now fully extended from the double stroke cylinder 9 ⁇ .
  • the position of the support lever 12 ⁇ and the bell crank 15 ⁇ is shown in FIG. 1. It can be seen how the alarm position can only be achieved with these elements, ie only with one drive element.
  • the processes described proceed in the opposite direction when the double-stroke cylinder is pressurized with compressed air. No further drive element is required for the closing movement either; the closing movement takes place by means of the double-stroke cylinder 9 as the only drive element in a convenient manner without manual operation.
  • the piston rod 8 ⁇ is retracted, the bell crank 15 ⁇ rotating about the pivot point 14 ⁇ and thus dragging the support lever 12 ⁇ back in a circular path about the second pivot axis 13.
  • the support lever 12 ⁇ forms a translation of the drive movement by the double-stroke cylinder.
  • the upper cross member can be moved back into the closed position, in which the locking device 16 engages automatically.
  • the locking force depends, as mentioned, on the mutual distances between the axis of rotation 2, the first and second pivot axes 11, 13 and the pivot point 14 and can thus be influenced in terms of design.
  • Fig. 1 is still an attachment 18 can be seen, which serves to integrate the four-bar mechanism with the smoke flap in a building, but does not contribute to the essential function of the four-bar system.
  • FIGS. 2 and 3 show the upper cross member, which essentially consists of strip-shaped end plates 19, 20 on both sides and an inverted U-shaped support 21 connecting them.
  • the cross member is shown reversed in Fig. 2 compared to the representation in Fig. 1, so that an attachment point 7a of the first end of the double-stroke cylinder on its piston rod in Fig. 2 is on the left side of the cross member.
  • This attachment point 7a forms a pivot bearing.
  • An attachment point for a second end 15b of the deflection lever - see FIGS. 8 and 10 - is therefore located beyond the center of the upper cross member on its right side.
  • the corresponding fulcrum bearing point in the upper cross member for the bell crank is designated 14.

  • the lifting cylinder 36 is not supported with its lowermost end on the first pivot axis 35, but further up towards its center. As a result, the lifting cylinder 36 is not in the closed position here illustrated flap to save space at an angle.
  • the flap is opened, when a piston rod 38 moves out of the lifting cylinder into the position 38 ⁇ and thus moves the upper cross member into the fully open alarm position 1 ⁇ , the lower section of the lifting cylinder 36 cannot hit the lower cross member 4.
  • the mode of operation of the support lever 37 and a deflection lever 39 is basically the same here as described in connection with the first variant of FIG. 1 above, so that repetition can be dispensed with here.
  • the position of the second pivot axis 13 on the support lever 37 and the pivot point 14 of the deflection lever 39 on the cross member 1 is also the same as in the first variant in Fig. 1, so that for the second pivot axis 13 and the pivot point 14 of the second variant the same reference numerals are used.
  • the location of the piston rod 38 on the cross member 1 is designated 7a.
  • the lower end of the deflection lever 39 which in the second variant is not mounted on the support lever 37 at the same point as the lifting cylinder 36, has a third pivot axis 40 on this support lever, specifically at the end of the support lever remote from the second pivot axis 13 37.
  • the particular advantage of the second variant according to FIG. 11 is due to the recognizable space-saving position of the lifting cylinder, which can be pivoted freely out of the lower part of the truss, that the length of the lifting cylinder and its stroke are largely freely selectable, so that even cylinders with a relatively long length Hub can be used.
  • the third variant of the joint arrangement according to FIG. 12 differs from the first variant according to FIG. 1 essentially in that in the third variant a lifting cylinder 41 with a lower end 42 is not pivotably mounted on a pivotable support lever, but on one with the Truss lower part 4 firmly connected drive carrier 33 or in another suitable manner, but in any case firmly on the truss lower part.
  • the corresponding third pivot axis, which is used for mounting the lifting cylinder 41 on the drive carrier, is designated here by 44.
  • a piston rod 45 of the lifting cylinder 41 is not connected to the upper cross member 1 as in the first variant of the joint arrangement, but with a first pivot axis 46 at an end of a support lever 47 remote from the second pivot axis 13
  • the arrangement of the second pivot axis of the support lever 47 is here again the same as in the first variant on the lower support bracket 5, so that here the second pivot axis is also provided with the reference number 13.
  • the piston rod 45 of the lifting cylinder 41 is not directly connected to the upper cross member 1 in the third variant of the articulated arrangement, but is only connected to it via a deflection lever 48, which is further supported here at the center at a pivot point 49 on the upper cross member is.
  • a major advantage of the third variant is that when the flap, which is also not shown here, is opened from the position of the elements of the joint arrangement shown in solid lines in FIG. 12 into a wide-open alarm position, which is shown with broken lines, torques on the upper part of the truss 1 are exercised, which are relatively large compared to the torques when closing from the alarm position.
  • the support lever of the second variant has one between pivot axis 35 located at its two ends, in contrast to the pivot axis of the first and third variants.
  • the attachment point of the piston rod is missing on the upper cross member of the third variant; on the other hand, a drive carrier for mounting the lifting cylinder is fixedly attached to the lower cross member, in contrast to the first and second variant.
