Definitions

  • the invention relates to an opening device with a sliding piece for an opening arm for a window, door or the like provided with an at least tiltable sash, which is guided in an undercut fitting groove of a frame made of extruded profiles and has an essentially U-shaped cross section at the ends of the free, by a flange interconnected legs arranged longitudinal webs to reach under the transverse webs delimiting the opening width of the fitting groove, and with a coupling opening in the flange of the slide for receiving a collar pin of the extension arm, which is used to limit the tilt opening width of the wing on a stop piece System arrives, the stop piece being fixed in place or, in conjunction with an additional extension arm, can also be arranged longitudinally displaceably in the fitting groove, and in the end tilt-open position of the sash, an additional securing means g for the wing comes into effect, consisting of a spring steel band fastened to the inside of the flange of the slide with a detent arranged on the free end projecting from the slide and
  • the supplementary protection consists of a spring steel strip which is arranged in a groove on the inside of the flange of the slider.
  • the free end of the spring steel strip protruding over the end of the slider is stepped down to a smaller width and carries the locking lug, which is bent approximately triangularly.
  • the latching lug is intended to cooperate with a latching cam on a further sliding piece designed as a stop piece, the latching cam on the underside of the flange of the same cross section as the slider having stop piece is attached.
  • the sliding piece and stop piece essentially have the dimensions of a drive rod and therefore only protrude slightly beyond the fitting groove, so that a low overall height is present.
  • This low overall height requires a very limited spring travel of the locking lug with a mutually small engagement depth, which limits the effect of the supplementary protection and the risk that the wing can be unintentionally released from the tamper-proof tilt opening position with relatively light wind or tensile forces acting on the tilt-opened wing becomes.
  • the extension arm is attached to the flange of the slide by means of a collar of the flange bolt. For reasons of ease of assembly, however, it can be advantageous to provide a detachable connection between the raising arm and the sliding piece.
  • the object of the invention is to provide a generic display device, in which a higher degree of security of the supplementary security is given, even at low end tilt opening positions, and wherein the extension arm is detachably secured to the slider without additional components.
  • the spring steel strip is bent in a U-shape in the direction of the free end of the slider from the area of attachment to the flange, with spring tongues formed by removing the bottom and extending essentially parallel to the legs of the slider and that, on the other hand, the spring steel strip extends adjacent to the inside of the flange beyond the coupling opening and is provided in the region of the coupling opening with a recess for securing the hooked-in collar pin of the extension arm against unhooking.
  • the spring steel band is formed as a flat band in the extension of the U-bottom, essentially lying against the inside of the flange of the sliding piece and protruding over the coupling opening for detachable hanging of the flanged arm of the extension arm in the flange of the slide.
  • the extension arm is secured against unwanted loosening by the spring steel band on the slide.
  • the spring steel strip thus takes on a double function, since it serves on the one hand as part of a supplementary protection and on the other hand as part of a protection against the unintentional detachment of the extension arm from the slide.
  • the coupling opening in the slider consists of a bore the size of the diameter of the collar of the collar pin of the extension arm with a connected extension with the diameter of the pin of the collar bolt, and the recess in the spring steel strip is arranged in the region of the extension, has one larger cross section than the diameter of the collar and is closed on the circumference educated.
  • the collar of the collar bolt must be fed into the hole in the coupling opening in the flange of the slider. The collar is then pressed onto the spring steel band and lifts it off the flange of the slide. As soon as the collar has come completely behind the flange, the collar bolt with the extension arm must be pushed against the extension of the coupling opening.
  • the collar comes into the area of the recess of the spring steel strip and the spring steel strip then springs back over the collar and comes back into contact with the flange of the slider. Since the recess is closed on all sides, an undesired moving back of the collar pin and thus the extension arm into the area of the bore of the coupling opening is prevented.
  • the edge of the recess opposite the widening of the coupling opening is provided with a bead.
  • the bead attached in the area of the spring steel band covering the bore of the coupling opening serves to enlarge the contact surface between the collar of the collar pin and the spring steel band.
  • the height of the bead can also be dimensioned such that it can get under the collar of the collar pin and thus a play-free articulation of the extension arm on the slide is made possible.
  • the flange of the slider is provided with an actuating opening which is arranged between the coupling opening and the end of the slider facing away from the spring tongues.
  • the actuation opening is thus freely accessible from the extension arm.
  • an actuating means such as a screwdriver, a nail and the like, pressure is exerted on the spring steel band through the actuating opening, which then extends from the inside of the Lifting the flange and thus clearing the hole in the coupling opening.
  • the extension arm can be laterally moved again and get into the area of the bore and is lifted off the slide and the release arm can thus be released from the slide again, after which the spring steel band is pressed back against the inside of the flange due to its spring force.
  • the stop piece In the area of the spring steel strip, the stop piece has a U-shaped cross section with a triangular cross section arranged on the parallel inner walls, the run-up surface facing the slide piece being flat and the holding surface to be gripped behind by the locking lugs being steeply inclined.
  • the latching lugs inside the stop piece come into contact with the run-up surfaces, are moved towards one another by them and are thus placed under prestress.
  • the pretensioning causes the locking lugs to move apart and thus snaps behind the holding surfaces of the locking cams. Due to the flat inclination of the run-up surface, gentle braking and bumping is achieved with a secure holding force of the supplementary safety device brought into effect due to the steeply inclined holding surfaces.
  • the opening device essentially consists of an opening arm 1, a sliding piece 2 that can be coupled to the opening arm 1 and a stop piece 3. Sliding piece 2 and stop piece 3 are intended to be received in an undercut fitting groove 4 of a sash frame made from extruded aluminum alloy profiles.
  • the opening width of the fitting groove 4 is limited by transverse webs 5, which are each projecting over the groove side walls 6.
  • the slider 2 has a substantially U-shaped cross section.
  • the legs 8 of the U-shape connected by the flange 7 are each provided at the free ends with two longitudinal webs 9 for engaging under the transverse webs 5 of the fitting groove 4, as shown in particular in FIG. 3. Since the legs 8 are placed at a greater distance outside the fitting groove 4, the U-shape has essentially been developed into an ⁇ shape.
  • a coupling opening 12 which consists of a bore 13 and a subsequent extension 14 with a smaller cross section.
  • An actuation opening 15 is also accommodated between this coupling opening 12 and the adjacent end of the slider 2.
  • a spring steel strip 16 is mounted in the recess 11 and is fastened to the flange 7 by means of a rivet 17. From the area of the attachment, the spring steel strip 16 is bent in a U-shape and protrudes beyond the sliding piece 2. Shortly after the attachment area, the bottom 18 and also part of the side walls 19 adjoining the bottom 18 are removed from the bent U-shape, so that two Spring tongues 20 arise which at their free end each have a locking lug 21 with an essentially triangular shape with run-up web 22 and holding web 23, which are arranged inclined to one another.
  • the spring steel strip 16 is formed in the extension of the bottom 18 of the U-shape as a pure flat piece 24, which extends beyond the area of the coupling opening 12 and the actuating opening 15 and ends shortly before the end face 25 of the sliding piece 2.
  • the spring steel band 16 has a recess 26 which overlaps the extension 14 of the coupling opening 12 on all sides and thus also projects into the area of the bore 13.
  • a bead 27 adjoins the recess 26, which is closed on all sides on the circumference, in the region of the bore 13 at the edge of the recess 26 and extends to both broad sides of the spring steel strip 16.
  • the extendable arm 1 which can be coupled to the slider 2, carries at its wing-side end a collar pin 28 comprising a pin 29 with a collar 30 of larger diameter arranged at the free end.
  • the stop piece 3 also has, at least at its end directed towards the spring tongues 20, a U cross-section, which on the parallel inner walls 31 each carries a latching cam 32 of triangular cross-section with a flat inclined run-up surface 33 which merges into a stronger and oppositely inclined holding surface 34.
  • the stop piece 3 is to be fixed in place in the fitting groove 4 by means of self-tapping screws 35, which partially perforate the transverse webs 5 of the fitting groove 4.
  • Fig. 1 the end tilt opening position of the wing is shown in function with the additional security.
  • the spring tongue end face 36 of the slider 2 lies directly on the front surface 37 of the stop piece 3.
  • the retaining web 23 of the latch 21 of the spring tongues 20 engages behind the holding surface 34 of the locking cam 32 of the stop piece 3.
  • the wing is thus secured against unintentional slamming by the holding force caused by the two locking lugs 21 engaging behind the locking cams 32.
  • the operator In order to overcome this holding force of the supplementary safety device, the operator must exert a conscious effort on the wing so that the latching noses 21 with their retaining webs 23 can move along the retaining surfaces 34 of the latching cams 32 under a movement towards one another until the latching lugs 21 reach the ramp surfaces 33 and are so that the spring tongues 20 move apart again with relaxation.
  • the locking lugs 21 slide into the securing position by snapping the locking cams 32 backwards simply because of the moment caused by the sash weight due to the weak inclination of the contact surfaces 33 of the locking cams 32.
  • the spring tongues 20 are accommodated in the U-cross section of the stop piece 3 in an effective position against contamination. They are located outside the fitting groove 4 so that a larger suspension travel can be used.
  • the collar 30 of the collar pin 28 has to be guided through the bore 13 of the coupling opening 12, which has a somewhat larger diameter than the diameter of the collar 30, and then against the flat piece 24 of the spring steel strip 16 to press in the area of the bead 27, so that the flat piece 24 moves away from the inside 10 of the flange 7 of the slider 2.
  • the extension arm 1 with the collar pin 28 is shifted to the right, as a result of which the pin 29 of the collar pin 28 reaches the extension 14.
  • a tool is to be passed through the actuation opening 15 provided outside the region of the extension arm 1 and the spring steel strip 16 is pressed away from the inside 10 of the flange 7, so that the return sliding path for the collar pin 28 is then released again.
  • the spring steel strip 16 thus serves both as part of the surcharge protection for the wing and as part of the safety catch for the extension arm 1.
