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 pivotably attached to a support lever about a first pivot axis, which in turn is pivotable about a stationary, second pivot axis in the vicinity of the pivot axis of the flap.
  • a known joint arrangement of the type mentioned at the beginning 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 upwards, 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 articulated 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, in addition to a first cylinder, which acts on the end of a support lever.
  • a third actuating element - motor or cylinder - is required.
  • the object of the present invention is to create a joint arrangement of a device with a flap which can be actuated completely automatically in and from an alarm position and which can be opened and closed over an entire large pivoting range, which can be up to approximately 165 °, with only one drive element allowed.
  • a hinge arrangement of the type mentioned in the preamble of claim 1 in a first variant in that the hinge 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, the first pivot axis of which lies approximately in the middle of the longitudinal extension of the support lever, that an additional deflection lever is pivotally arranged at a first end on an end of the support lever remote from the second pivot axis, and in that a second end of the deflection lever pivotably engages the cross member of the flap at a distance from its axis of rotation and from the attachment point of the first end of the drive element.
  • 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 deflection lever 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 when opening or closing, will abut a cross member on which the flap is pivotally mounted.
  • 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 around a first
  • the pivot axis is pivotally attached to a support lever, which in turn is pivotable about a stationary, second pivot axis in the vicinity of the axis of rotation of the flap.
  • the stated object is achieved in that the articulation arrangement has only one linear drive element, on the first pivot axis of which there is an additional deflection lever with a first 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.
  • 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 takes into account the greater load when opening, especially due to snow or ice.
  • the third variant of the joint arrangement requires 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.
  • the fixed, third pivot axis, about which the drive element can be pivoted is further preferably connected to a fixed, second cross member, which can be done via a drive carrier which is attached to the cross member.
  • the third swivel axis is located there the first axis of rotation, about which the flap can be pivoted, deeper and horizontally further, ie at a greater horizontal distance than the second pivot axis, about which the support lever can be pivoted.
  • a double-stroke cylinder is advantageously used as a linear drive element.
  • the first and the second pivot axis can simultaneously serve for supplying the compressed air to the lifting cylinder, according to claim 8, the first pivot axis and the second pivot axis each serving as rotary unions for the supply of the pressure medium to the lifting cylinder are formed. 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 hinge 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 a second pivot axis 13, which is also realized by a rotary leadthrough, at the lower end of the support bracket 5.
  • 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 lifting 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 second pivot axes 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 cross member 1 and the forces occurring during this movement, which are exerted in particular by the double-stroke cylinder 8 on the 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 pressed out of it, the locking device is released first, which allows the upper cross member 1 and the smoke extraction flap connected to it to pivot up.
  • the double-stroke cylinder 9 is supported on the support lever 12 on the pivot bearing 11, which, however, cannot deflect downwards in a clockwise direction due to 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 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. 2-10 For individual components of the joint arrangement described, reference is made below to FIGS. 2-10:
  • 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 upper part is shown reversed in FIG. 2 compared to the illustration in FIG. 1, so that an attachment point 7a of the first end of the double-stroke cylinder lies on the piston rod of the latter in FIG. 2 on the left side of the cross member upper part.
  • 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.
  • FIGS. 4 and 5 show a corresponding lower cross member 4, on which the described upper cross member comes to rest when the flap is closed.
  • the lower part of the truss essentially consists of two end angle pieces 22 and 23, which are connected to one another by struts 24 and 25 running parallel to one another.
  • the struts also consist of angle profiles.
  • the support bracket 5 projects downward from the end angle piece 22. It is connected to the struts 24 and 25 at its lower end via a support 6, which is designed as a double support.
  • the second pivot axis 13 is provided for the support lever 12 - see FIG. 1.
  • FIG. 6 is the mutually parallel angle profiles 26 and 27, which are mutually by angle pieces 28 and 29 are connected, existing support lever shown.
  • At one end 12a there are bores which form parts of the first pivot axis.
  • Rotary unions for the double-stroke cylinder, not shown, can be mounted in the bores.
  • the second pivot axis 13 is also provided with rotary unions.
  • the longitudinal section in FIG. 6 runs in the section plane BB, which is indicated in FIG. 7.
  • FIGS. 8-10 show different views of the deflection lever, of which FIG. 8 again shows a longitudinal section along a central plane, here C-C in FIG. 10.
  • the longer section of the bell crank consists of two angle profiles 30 and 31, which are connected to one another by angle pieces 32 and 33 at a parallel distance.
  • the angle piece 32 is oriented so that it forms a closed front.
  • On this a box-shaped end piece 34 is welded, which is so narrow that it fits between the legs of the U-beam 21 of the upper cross member and is easily pivotable between them.
  • the corresponding pivot point 14 - see Fig. 1 - is located at the end 15b of the bell crank.
  • the opposite first end 15a is pivotable about the first pivot axis 11 - see FIG. 1 - and has holes for the pivotable mounting.
  • Variants for example in the form of a hydraulic cylinder or an electric motor with a spindle, are possible for the linear, straight-line drive element, which is designed as a pneumatic double-stroke cylinder according to FIG. 1.
  • the relative positions of the pivot axes, the axis of rotation and the pivot point which are the four-bar linkage form, selectable so that in particular the opening and closing forces can be influenced.
  • the lower end of the double-stroke cylinder 9 can also be articulated at intermediate points of the support lever 12 between its ends 12a and 12b. It is also possible to pivotally mount the cylinder on an extension of the support lever which extends beyond the end 12a. Corresponding variations of the upper attachment point 7a of the double lifting cylinder on the upper cross member are possible.
  • the locking device 9a can be designed as a pneumatic or hydraulic or mechanical lock with a separate drive element; However, the actuation discussed by the double-stroke cylinder is expedient.
  • the same parts as in the first variant are provided with the same reference numerals.
  • the elements in the fully open alarm position are again distinguished from the same elements in the rest position in that the reference numerals of these elements are provided with two lines in the alarm position.
  • the second variant according to FIG. 11 differs from the first variant of the joint arrangement according to FIG. 1 essentially in that in the second variant a first pivot axis 35 of a lifting cylinder 36 serving as the drive element is laid approximately in the middle of the longitudinal extent of a support lever 37.
  • 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 omitted 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 here 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 supported at the same point as the lifting cylinder 36 on the support lever 37, 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 special advantage of the second variant according to fig. 1 is due to the recognizable space-saving position of the lifting cylinder, which can be pivoted freely from the lower cross member, that the length of the lifting cylinder and its stroke are largely freely selectable, so that cylinders with a relatively long stroke 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 denoted 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 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 connected directly to the upper cross member 1, 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 opening the flap, also not shown here, from the position of the elements of the joint arrangement shown in solid lines in FIG. 12 to a wide-open alarm position, which is shown with broken lines, torques on the cross beam 1 are exercised, which are relatively large compared to the torques when closing from the alarm position.
  • the upper cross member, the lower cross member, the support lever and the bell crank can be of the same or at least quite similar design in all three variants.
  • the support lever of the second variant has one between pivot axis 35 located at both 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.
