Definitions

  • the invention relates to an opening scissors for the sash of a window, a door or the like sitting in a frame, in particular a skylight opener designed as flat-shaped scissors, with a fitting which can be fastened to the frame and which has a rail, with a longitudinally adjustable guided drive thereon Actuating element and with an actuator, the rear end of which is articulated on the fitting, the front end of which can be articulated on the wing and on which a control lever articulates in between, which is articulated on the fitting and has a control cam which is tapped by the actuating element, to pivot the control lever and thus the actuator.
  • Such a scissor stay is known from practice. It has an actuator in the form of a rigid, straight arm, which is articulated with its rear end on a slide, which is longitudinally adjustable on the rail and runs along the control cam when actuated. With this form of articulation, the rear end of the extension arm is immediately adjacent to the fitting in all wing opening and closing positions. The length of the extension arm is therefore determined by the desired adjustment stroke of the opening scissors. If this is large, the extension arm must be long. A long extension arm can now be used for certain applications, e.g. B. the tilt actuation of round skylights, act disproportionately, especially if the extension arm blinds the fitting in the wing closed position and determines the overall length of the stay scissors.
  • the tilt actuation of round skylights act disproportionately, especially if the extension arm blinds the fitting in the wing closed position and determines the overall length of the stay scissors.
  • the object of the invention is to provide a stay scissors of the type mentioned which builds shorter for the same actuating stroke, in particular has a shorter extension arm which preferably blinds the fitting in the wing closed position, or in other words with the same overall length, in particular the same length of the fitting in the Wing closed position preferably facing blind arm, has a larger stroke.
  • the essence of the invention is therefore to provide, as an actuating member, instead of the known rigid, straight raising arm, a pair of articulated levers consisting of a release lever and raising arm, the latter preferably fulfilling the function of covering the fitting in the wing closed position.
  • the articulation point of the actuating member on the wing has an approximately linear actuating path over the entire actuating stroke. This makes it possible to design the wing pivot point as a fixed point at which no sliding lateral displacements have to take place. It is therefore not necessary at this point for sliders or the like, which could become soiled during the construction period and become stuck.
  • release lever and extension arm Due to the fact that the release lever and extension arm almost coincide with each other in the wing closed position and spread when the wing is opened, the length of the stay scissors is saved by just under the length of the release lever. Release lever and extension arm form a knee with an approximately extended position and maximum drive reduction near the wing closed position.
  • the course of the control curve on the control lever is corresponding. It is a high closing force and a sensitive setting of a small opening angle z. B. guaranteed for ventilation purposes.
  • the release lever can be articulated with an axis parallel to the articulation axis of the control lever on the same fitting part as the control lever and can be pivoted essentially in the same direction with the control lever.
  • the rear end of the deployment arm is articulated on the release lever, again with a parallel axis, the front end of which can be articulated on the wing and on which the control lever articulates in between.
  • release lever and control lever extend essentially parallel, while release lever and extension arm enclose an acute to approximately right or obtuse angle.
  • the fitting pivot axis of the release lever, the hinge axes of the release lever and control lever on the extension arm and the tapping of the control cam with the actuating element preferably essentially form the corners of a lever parallelogram.
  • the control curve can be S-shaped.
  • the actuating element is driven with a push / pull rod which passes through the center of the guide rail in the longitudinal direction.
  • the push / pull rod is preferably a round rod.
  • the actuating element preferably includes a sliding-rotating sleeve, which is seated on the push / pull rod and is rotatably and axially fixedly coupled thereto, with a circular-cylindrical jacket portion, the circumferential extent of which is at least in sections more than 180 ° and with which the sleeve is guided in the rail.
  • a plate (tapping plate) preferably extends from the sleeve and bears a cam that picks up the control cam.
  • the release lever and the control lever are preferably articulated on a plate (articulation plate) which comes from a rotating sleeve which is rotatably seated on the push / pull rod and is axially fixed to the fitting.
  • the latter has a circular cylindrical outer surface with a circumferential extent of at least more than 180 ° in sections and is thus guided in the rail.
  • the tapping plate and articulation plate accommodate the release lever and control lever between them.
  • the widest possible opening of the sash can be determined by abutment of the sliding rotating sleeve on the rotating sleeve.
  • the tapping plate is preferably provided with a hook opening into which a pin attached to the opening arm runs when the wing is closed.
  • the tap plate also has the function of closing and locking the sash.
  • the extension arm is preferably hollow, open towards the fitting and suitable for receiving plates and levers when the sash is closed.
  • the extension arm thus has the advantageous function already mentioned at the beginning of blending the fitting in the wing closed position.
  • the invention also relates to the articulated lever mechanism of a stay scissors of the type mentioned.
  • protection is claimed for the mechanism covered by the stay arm in the closed state, which can also be important for other applications.
  • the mounting bar 10 of the stay scissors according to the invention is an elongated rectangular sheet metal strip which comes into contact with its back against the frame of a window, a door or the like and is fastened to it with three screws offset over its length. 12 are mounting holes for the screws.
  • the mounting strip 10 has three substantially rectangular punched-outs 14 offset along its length, by means of which the tongues projecting therein are divided. The tongues are bent forward into claws 16. They point to the side in the same direction. At one end, the mounting bar 10 carries a pin 18 projecting forward, which is cylindrical and graduated in diameter.
  • a leaf spring strip 20 is riveted to the front of the mounting bar 10, which extends in the longitudinal direction thereof, has a portion 22 protruding laterally from the mounting bar 10 and bears a circular locking lug 24 at the front on this portion 22.
  • the rail 26 belonging to the fitting of the stay scissors essentially has a rectangular U-profile. It is attached with its U-back 28 to the mounting bar 10 so that the U-legs 30 protrude. In an extension of the U-legs 30, low edge webs 32 extend from the U-back 28 on both sides, which overlap the mounting strip 10. Strictly speaking, the rail 26 has an essentially rectangular double T-profile with a deep front and a flat rear U-profile, which have a common U-back.
  • the U-back 28 of the rail 26 has three punched-outs 34 through which the tongues projecting therein are divided.
  • the tongues are bent backwards to claws 36, which are located at a position corresponding to the claws 16 of the mounting strip 10 and point to the side in the opposite direction as this.
  • a window 38 is punched into which the section of larger diameter 40 of the pin 18 fits and through which the section of smaller diameter 42 of the pin 18 projects into the profile opening of the front U-profile.
  • an opening 44 is punched out of the U-back 28, into which the locking lug 24 fits.
  • the rail 26 For attachment to the mounting bar 10, the rail 26 is slipped onto it from the front, the claws 16 of the mounting bar 10 in the punched-outs 34 and the pins 18 of the mounting bar 10 coming to rest in the window 38 of the U-back 28 of the rail 26. The rail 26 is then pushed to the side, the claws 16, 36 interlocking with one another. It goes without saying that punched-outs 34 and windows 38 of the U-back 28 offer the necessary sliding play.
  • the leaf spring strip 20 with the locking lug 24 is deflected and tensioned by the running rail 26. The locking lug 24 springs into the opening 44 and thereby locks the rail 26.
  • the leaf spring strip 20 can be depressed at its end 46 projecting slightly beyond the rail 26 and the latch 24 can be lifted out of the opening 44.
  • Two fitting parts 48, 50 are guided in the rail 26 and are used to move an opening arm 52 of the opening scissors.
  • the raising arm 52 is articulated with its front end, which is the left in the drawings FIGS. 1 and 7 to 13, on the wing to be actuated.
  • the opening arm 52 has a cylindrical opening 54, in which a pivot pin of the wing engages with rotational play.
  • the extension arm 52 is provided with a latching and releasing mechanism for the pivot pin, which is of no further interest here.
  • the extension arm is a hollow body with an elongated prismatic housing, the length of which corresponds approximately to that of the rail 26.
  • the upper and lower cover plates 56 of the housing have a straight edge 58 at the rear, while they taper towards the front in a trapezoidal shape.
  • the housing is open on its rear side 60 facing the rail 26 and is otherwise closed on all sides.
  • the raising arm 52 comes to lie directly in front of the rail 26. He picks up the fittings inside his housing and covers the fitting.
  • the stay scissors 52 are operated with a push / pull rod 62 which is accommodated with all-round play in the front U-profile opening of the rail 26 and passes through the middle in the longitudinal direction.
  • the push / pull rod 62 is a round rod. At the same time, it forms the axis of rotation for the two fitting parts 48, 50, each of which sits on the rod 62 with an essentially circular cylindrical sleeve 64, 66 that is open over the circumference.
  • the sleeves 64, 66 have a circumferential extent of approximately 300 °. They are mounted on the rod 62 with rotational play and guided with their circular-cylindrical outer jacket part on the U-legs 30 of the front U-profile of the rail 26.
  • the U-legs 30 have concave profile bulges 68 in the form of circular segments, the edge of which follows a circle around the central axis of the rail 26, in which the push / pull rod 62 lies.
  • the left fitting part 48 in FIGS. 1 and 7 to 13 is axially fixed to the rail 26.
  • a flat articulation plate 72 attaches to the sleeve 64 belonging to the left fitting part 48, which unloads forwards from the rail 26 and extends in the direction towards the fitting part 50 on the right in FIGS. 1 and 7 to 13 .
  • a release lever 74 is articulated on the articulation plate 72 at the rear right and a control lever 76 at the front left.
  • the articulation axes 78, 80 are directed parallel and perpendicular to the plane of the articulation plate 72.
  • the release lever 74 is articulated at the other end to the rear end of the deployment arm 52.
  • the control lever 76 articulates 84 on the deployment arm 52 between the articulation axis 82 of the release lever 74 and the opening 54 for the articulation pin of the window sash. Its articulation axis 84 is closer to the 82 of the release lever 74 than the latter opening 54.
  • the articulation axes 82, 84 of the levers 74, 76 on the deployment arm 52 are parallel to those 78, 80 on the articulation plate 72.
  • Release lever 74 and control lever 76 are flat parts made of sheet metal.
  • the release lever 74 is cranked.
  • the control lever 76 has an irregular shape, which essentially results from the course of a control curve 86 therein.
  • the control cam 86 is a substantially S-shaped slot-like punching of constant width, which extends over the length of the control lever 76.
  • the right-hand fitting part 50 in FIGS. 1 and 7 to 13 is axially fixed to the push / pull rod 62, so that it takes part in the axial adjustment movement thereof.
  • the driver block 88 is the push / pull rod 62 with a stud 90 at the desired location locked. It sits in a recess 92 of the sleeve 66 belonging to the right fitting part.
  • the recess 92 extends in the circumferential direction of the sleeve 66.
  • the driver block 88 allows the sleeve 66 to rotate about the push / pull rod 62.
  • a flat pick-up plate 94 attaches to the sleeve 66 belonging to the right fitting part 50, which unloads forwards from the rail 26 and extends in the direction towards the left fitting part 48.
  • the tapping plate 94 of the right 50 and the articulation plate 72 of the left fitting part 48 receive the release lever 74 and the control lever 76 between them.
  • the tapping plate 94 carries a round cam 96 which projects through the control curve punched out of the control lever 76 with play in displacement and taps off the control curve 86.
  • the cam 96 On the other side of the tap plate, the cam 96 has a head which has an enlarged diameter and does not fit through the cam punching, so that the cam 96 holds the tap plate 94 and the control lever 76 together.
  • the control cam 86 is tapped off at a point which essentially forms the corners of a lever parallelogram with the fitting articulation axis 78 of the release lever 74 and the articulated axes 82, 84 of the release lever 74 and control lever 76 on the extension arm 52.
  • Release lever 74 and control lever 76 are directed essentially parallel in all phases of movement of the window sash.
  • Release lever 74 and deployment arm 52 close a small point in the wing closed position Angle on.
  • the latter levers 74, 52 form a pair of toggle levers which, in the wing closed position, assume an approximately extended position in coverage with themselves.
  • the sleeves 64, 66 of the two fitting parts 48, 50 move towards one another.
  • the maximum open position of the window sash is determined by the stop of the sliding rotating sleeve 66 carrying the tapping plate 94, connected to the push / pull rod 62, against the rotating sleeve 64 carrying the articulation plate 72 and axially fixed to the rail 26.
  • the tapping plate 94 has a hook opening 98, into which a pin 100 is inserted when the wing is closed and extends between the cover plates 56 of the extension arm housing.
  • a cutout 102 in the control lever 76 clears the way for the pin 100 into the hook opening 98.
