Definitions

  • the invention relates to a swinging wing bearing with a frame bearing part and a wing bearing part and a rocker arm connecting both, one end of which is rotatably supported on the frame bearing part and the other end on the wing bearing part about a first and subsequently or simultaneously about a second axis of rotation, the end facing away from the room of the bearing is closed at its lower end in the installed position by a lower cover plate of the frame loader part and at its upper end by an upper cover plate of the wing bearing part.
  • a swing wing bearing is known from DE-C-1708217. Swing wing bearings are usually used to support the swing wing of a window, with the bearing axis running horizontally through the center of the wing. Rotating the wing about the first axis of rotation causes it to be inclined by a predetermined angle of rotation.
  • This position is used as the ventilation position of the window. If you then turn the wing about its second axis of rotation, the wing outer surface enters the interior, while the inner wing surface now points outwards. This position is intended as a cleaning position, since it allows the outer surface of the wing to be cleaned effortlessly from inside the room. The wing assumes a position parallel to its closed position, however, it is offset towards the interior of the room.
  • the sash and frame of modern swing windows are preferably made of aluminum or plastic profiles, but wooden frames are still in use.
  • the profile systems have both internal and external seals, so that drafts can practically not occur in the actual frame area. Because the upper wing half of a swing-wing bearing swivels into the interior of the room with a rotation around the first axis of rotation, while the lower wing half is moved outwards, a change in the sealing plane must take place in the bearing itself. This fact and also the well-known design of the swing wing bearings lead to creeping paths for drafts occurring in the swing wing bearing. If there is a leak at any point in the outer seal due to a processing or material defect, the air can enter the gaps between the alternating profile and the main profiles.
  • the swing-wing bearing remains as a display point for the passage of this air into the interior of the room. The user is therefore of the opinion that the oscillating-wing bearing as such would be leaky, even though the air entry took place at a different location.
  • the object of the invention is consequently seen in developing a swing-wing bearing of the type described at the outset in such a way that air passage is prevented with little effort and without increasing the tolerance requirements.
  • the swing-wing bearing is designed in accordance with the preamble of claim 1 in accordance with the characterizing part of this claim.
  • a rebate overlaps a rollover, and due to the leaking seal in the two pivoting wing bearings, there is also a leaping seal in the pivoting wing bearing seal formed by rollover and rebate, which enables the pivoting wing to move first about the first and subsequently or simultaneously about the second axis of rotation .
  • the width of the rebate and rollover depend on the tolerances in the manufacture of frame and sash as well as the amount by which the frame and sash bearing part can be pulled apart in the longitudinal direction of their axes of rotation if unfavorable tolerances and stresses. All of the above and the following explanations relate to the closed window and the built-in swing-wing bearing, for an observer standing inside the room.
  • the front end of the bearing is accordingly the end of the bearing which has visible surfaces and which faces the interior of the room.
  • the first axis of rotation lies below the second axis of rotation.
  • the frame bearing part have a fold extending from its upper end to the height of the first axis of rotation, and the rocker arm on its longitudinal edge assigned to the frame bearing part have a first projection which is laterally protruding and engages in the fold and has approximately the same length.
  • a fold of fold and rollover then takes place on the first axis of rotation, because with the Tilting movement of the wing about the first axis of rotation, pivot the upper part of the rocker arm with the wing bearing part into the interior, while the lower part is pivoted outwards. These swiveling movements must of course not be hindered by the fold extending into the neighboring part.
  • first sealing strip projecting laterally beyond the first rollover, which extends from the lower rocker arm end to approximately the height of the first axis of rotation and an edge at the lower end of the Reaches behind the frame bearing part.
  • This first sealing strip is advantageously molded on.
  • the length of the said edge corresponds at least to the length of the first sealing strip.
  • the piece of the latter located below the first axis of rotation and extending the fold on the frame bearing part is addressed.
  • the edge of the frame bearing part, which is engaged by the first sealing strip when the sash is closed, lies laterally next to the fold, that is to say further from the center of the rocker arm than the fold of the frame bearing part.
  • Another variant of the invention is characterized by a recess in the frame bearing part, the lower end of which is arched and shaped like a staircase, the radius of the arch corresponding to the radius of the movement path of the lower end of the rocker arm.
  • This recess is located essentially below the first axis of rotation, as seen from the interior of the room, starting behind the rear edge of the frame bearing part. It then extends to the lower cover plate of the frame bearing part. This creates an approximately wedge-shaped shape of the recess.
  • Their depth corresponds to the amount by which the first sealing strip protrudes laterally beyond the first rollover. With regard to the first landing, the depth corresponds to the width of the first rollover.
  • the end of the recess facing the lower cover plate also forms a stop for the rocker arm.
  • This stop limits the first rotary movement, i.e. the transfer of the wing from the closed position to the ventilation position.
  • another stop in the bearing can also be provided for this first rotary movement. In the case of a swing-wing bearing with simultaneous rotation about both axes, such a stop is not necessary.
  • the rocker arm on its longitudinal edge assigned to the wing bearing part has a laterally projecting second rollover from its lower end to the level of the second bearing axis, which folds into a fold extending from the lower end to the level of the second axis of rotation of the wing bearing part engages.
  • This is part of the seal between the rocker arm and the wing bearing part u. up to the second axis of rotation, where there is also a jump in the sealing plane, analogous to the jump between the frame bearing part and the rocker arm on the first axis of rotation.
  • This leap in the sealing plane takes place to the side. I.e. the parts of the sealing plane above and below the sealing step both lie in a common plane, but they are laterally offset from one another.
  • Another embodiment of the invention provides that at the upper end of the rocker arm on its longitudinal edge assigned to the wing bearing part there is a second sealing strip which projects laterally beyond the second flap and which engages behind an edge at the upper end of the wing bearing part which resets laterally with respect to the fold of the wing bearing part is. This creates the upper part of the seal between the rocker arm and wing bearing part, which extends from the upper end of the swing arm bearing to about the second axis of rotation.
  • the second sealing strip is located in a very advantageous manner on an element which is detachably held on the rocker arm or the second axis of rotation.
  • the element forms a brake part of the bearing, which is detachably connected to the upper rocker arm end and has or receives an element which acts in the manner of a sliding block or the like and which fits into a circumferential groove of one of the engages second axis of rotation forming pin of the wing bearing part.
  • the element acting as a sliding block can be the previously known screw-in element or a screw. Its shaft engages tangentially in the circumferential groove of the bearing journal.
  • a strip-like sealing element is attached to the upper and lower end face of the plate-like part of the rocker arm. It can be a circular cross-section that is pressed into a corresponding groove Act sealing element. To the left and right of this, a sealing element between the bearing and the further spar can also be used at the front end area of the frame or wing bearing part. In a comparable manner, the gap between the lower cover plate of the frame bearing part and the upper cover plate of the wing bearing part can also be sealed by switching a strip-like sealing element fastened to one of the cover plates between the facing end edges of the upper and lower cover plate.
  • the sealing element itself can have a strip-like shape. Instead, however, it can also be a molded-on strip of a plate which is attached to the inner surface of either the lower or the upper cover plate, for example by gluing.
  • the three most important elements of the swing wing bearing are the wing bearing part 1, the rocker arm 2 and the frame bearing part 3.
  • the rocker arm 2 is rotatably connected to both the wing bearing part and the frame bearing part, the first axis of rotation 4 serving for the pivotable articulation of the rocker arm on the frame bearing part 3, while the second axis of rotation 5 causes the rotatable articulation of the rocker arm on the wing bearing part 1.
  • Both rotary movements are limited and can only be carried out successively in a known manner. First, the wing is rotated about the first axis of rotation 1 into an oblique position, which serves as the ventilation position of the wing. The wing can then be rotated further until it has made a total of 180 ° rotation.
  • the outside pane is then easily accessible from the interior of the room, so that it can be cleaned without problems.
  • the sash assumes an inward parallel position, so that even in the rotating end position, the space can be ventilated via the gaps between the frame and sash frame.
  • the rotary movement of the wing is braked by means of a preferably adjustable brake, while a positive control, as said, ensures the successive sequence of the two rotary movements when opening and closing the wing.
  • Both the wing bearing part 1 and the frame bearing part 3 have an angular shape, whereby in the case of the wing bearing part 1 the one angle leg is formed by the upper cover plate 6 and in the frame bearing part 3 the one angle leg is formed by the lower cover plate 7.
  • the two cover plates are each shorter than the adjacent longitudinal edge of the other leg of the bearing part in question. When the bearing is closed, the two cover plates are directly one above the other, and together they form a bearing housing wall which is located inside the frame and points outwards. The gap between the two cover plates is sealed by means of a strip-like sealing element which is used on one of the two end edges, in particular on the upper end edge 9 of the lower cover plate 7.
  • This upper end edge 9 is shaped like a trough to form a retaining groove for the strip-like sealing element. Opposite is an inclined lower front edge 10 of the upper cover plate 6, which is pressed firmly against the strip-like sealing element 8 when the bearing is closed.
  • the rocker arm 2 consists essentially of the bearing leg 11 with the bearing bore 12 for the first axis of rotation 4 consisting of a pin and the plate-like part 13 arranged at right angles thereto. Its surface facing the interior forms a visible surface 14 of the swing-wing bearing. To the left of this is the visible surface 15 of the wing bearing part 1 in the installed state of the bearing and to the right of it the visible surface 16 of the frame bearing part 3.
  • the visible surface 15 is located at the front end region 17 of the wing bearing part and the visible surface 16 at the front end region 18 of the frame bearing part 3.
  • the plate-like part 13 of the rocker arm 2 and the front end regions 17 and 18 of the leaf or the frame bearing part are mutually folded and folded over sealed, as will be explained in more detail below. As a result, any outside air that may have entered the interior of the swing-wing bearing cannot escape into the interior of the room.
  • the frame bearing part 3 has a fold 19 extending from its upper end 20 to the level of the first axis of rotation 4. When the sash is closed, it is overlapped by a first flap 21 which is located on the Frame bearing part 3 associated longitudinal edge 22 of the rocker arm 2 is located. The length and shape of the flap 21 correspond to that of the fold 19. In addition, the flap 21, as shown in FIG. 3, is flush with the visible surface 14. At the lower end 23 of the rocker arm 2 there is a first on the longitudinal edge 22 associated with the frame bearing part 3 Rollover 21 laterally projecting first sealing strip 24. Its lower end also follows the front end region 18 of the frame bearing part 3, as is the case with the upper end of the first rollover 21 and the fold 19.
  • this first sealing strip 24 extends from the lower rocker arm end 23 to approximately the height of the first axis of rotation 4.
  • the frame bearing part 3 is provided with a recess 26, the shape and size and arrangement of the frame bearing part 3 with respect to the first axis of rotation 4 depends on the size and movement path of the first sealing strip 24. Because the latter is set back in relation to the plane of the plate-like part 13 of the rocker arm 2, the recess 26 is shaped like a step at its lower end 27.
  • the rocker arm is shaped in an arc shape there according to the radius of movement of the lower end of the first sealing strip 24.
  • the end 28 of the recess 26 facing the lower cover plate 7 on the frame bearing part 3 at the same time forms a stop for the rocker arm 2. It limits its swing-open movement relative to the frame bearing part 3 and it cooperates with the lower end 23 of the rocker arm 2. Otherwise, the rocker arm has at this lower end 23 as well as at its upper end 29, u. on the plate-like part 13, a receiving groove 30 or 31 for a stiffened sealing element, not shown, which can correspond to that 8 at the upper end of the lower cover plate 7.
  • the rocker arm 2 has, on its longitudinal edge 32 assigned to the wing bearing part 1, a second rollover 34, which extends from its lower end 23 to the level of the second bearing axis 5 and projects laterally to the left (FIG. 2) and also ends flush with the visible surface 14. When the bearing is closed, it engages in a fold 36 of the wing bearing part 1 which extends from the lower end 35 to the level of the second axis of rotation 5.
  • a circumferential groove 41 is provided, in which tangentially the shaft of the mentioned fastening screw for the element 38 engages and thereby brings about the axial securing of the rocker arm 2 on the pin 5 without hindering the relative rotation of the rocker arm and wing bearing part.
  • the second sealing strip 37 engages behind an edge 42 at the upper end of the wing bearing part 1. This is set laterally to the left relative to the fold 36 (FIG. 1).
  • the fold 19 and the flap 24 on the one hand and the fold 36 and the flap 37 on the other hand each abut one another on the end face when the bearing is closed, so that a seal is also achieved at these points.
