Die Sekundärwendebiegung dient jeweils als formschlüssig hintergreifender Haken für ein Leichtprofil, die in der Höhe des Leichtprofils um 90° abgewinkelten Schenkel sind zusammen mit einer leicht gekröpften Primärwendebiegung als einklipbarer Haken ausgebildet, welcher die Breite des Leichtprofils hintergreift.After US3163266 is used as a quick connector for one-handed installation of two perpendicular to each other oriented, each continuous lightweight profiles a resilient wire bow, which has a primary deflection of 150 ° centrally and their legs each have a perpendicular secondary turn deflection of 180 °.

Im wesentlichen besteht der als Schnellverbinder ausgebildete Drahtbügel aus einem gebogenen Drahtstück aus zumindest teilweise federelastischem Metall zwischen 2 und 8 mm Durchmesser, wobei der Drahtbügel bezüglich einer, zur einseitigen Aufnahme des Eingussdübels ausgebildeten, bei halber Länge mit einem Radius grösser oder gleich dem nicht radial aufgeweiteten Durchmesser eines zugeordneten Eingussdübels ausgebildeten, Primärwendebiegung zwischen 90° und 180° mit spiegelsymmetrisch zur winkelhalbierenden Ebene ausgeführten Schenkeln ausgebildet ist, wobei jeder Schenkel eine, zur einseitigen Aufnahme eines zugeordneten Armierungseisens ausgebildete, im wesentlichen senkrecht zur Primärwendebiegung gebogene Sekundärwendebiegung zwischen 90° und 360°, mit einem Radius grösser oder gleich dem Durchmesser des Armierungseisens ausbildet und jeweils endseitig ein, im wesentlichen senkrecht zur Primärwendebiegung gebogener, im Winkel zwischen 30° und 90° abgewinkelter, einklipbarer Haken angeformt ist, welcher in den radial äusseren Stirnbereich der endseitigen radialen Aufweitung des Eingussdübels kraftformschlüssig einfedernd ausgebildet ist.Essentially designed as a quick connector wire hanger consists of a bent wire piece of at least partially resilient metal between 2 and 8 mm in diameter, wherein the wire hanger with respect to a, for one-sided inclusion of the sprue formed at half the length with a radius greater than or equal to the not radially expanded Formed primary shaft bend between 90 ° and 180 ° with mirror-symmetrical to the bisector plane running legs, each leg one, designed for one-sided recording of an associated reinforcing iron, bent substantially perpendicular to the primary turn bend secondary turn deflection between 90 ° and 360 °, with a radius greater than or equal to the diameter of the reinforcing iron forms and each end one, bent substantially perpendicular to the primary turn, bent at an angle between 30 ° and 90 °, einklipbarer hook is formed, which is formed in a frictional force-locking manner in the radially outer end region of the end-side radial expansion of the sprue plug.

Je Schenkel ist zwischen der Sekundärwendebiegung und dem einklipbaren Haken eine Tertiärwendebiegung zwischen 90° und 270° angeordnet, wodurch sich im eingeklipsten Zustand die Sekundärwendebiegung in einen Winkel grösser 180° deformiert, welche das durchgängige Armierungseisen beidseitig kraftformschlüssig in sich festlegt.Each leg is a Tertiärwendebiegung between 90 ° and 270 ° disposed between the secondary turn bend and the clip clip, which deforms in the clipped state, the secondary turn deflection at an angle greater 180 °, which defines the continuous reinforcing bars on both sides form fit in itself.

Nach Fig. 3 bildet der erfindungsgemässe Schnellverbinder weiter im Vergleich zu den in Figur 1 und 2 gezeigten, nicht erfindungsgemäßen Schnellverbinden je Schenkel 5, 5' zwischen der, senkrecht zur Primärwendebiegung 3 gebogenen und entgegen der endseitigen Richtung des Eingussdübels 2 orientierten, Sekundärwendebiegung 6, 6' mit β = 180° und dem im Winkel von 90° abgewinkelten, einklipbaren Haken 8, 8' eine, jeweils parallel zur Primärwendebiegung 3 und senkrecht zur Sekundärwendebiegung 6, 6' zur winkelhalbierenden Ebene 4 hin gebogenen, Tertiärwendebiegung 11, 11' im Winkel γ=180° aus. Je Schenkel 5, 5' ist zwischen der Tertiärwendebiegung 11, 11' und dem einklipbaren Haken 8, 8' eine zur Sekundärwendebiegung 6, 6' parallele Quartärwendebiegung 12, 12' mit dem Winkel δ=90° angeordnet.To Fig. 3 forms the quick connector according to the invention further in comparison to those in FIG. 1 and 2 shown, non-inventive quick connect each leg 5, 5 'between the bent perpendicular to the primary turn 3 and opposite the end direction of the sprue 2 oriented, secondary turn 6, 6' with β = 180 ° and the angled angle of 90 °, clip-hook 8, 8 'one, in each case parallel to the primary turn bend 3 and perpendicular to the secondary turn bend 6, 6' to the bisecting plane 4 out bent, Tertiärwendebiegung 11, 11 'at an angle γ = 180 °. Each leg 5, 5 'is between the Tertiärwendebiegung 11, 11' and the einklipbaren hook 8, 8 'a secondary deflection for secondary 6, 6' parallel Quaternary deflection 12, 12 'arranged at the angle δ = 90 °.

Claims (3)

  1. Quick-coupling device for fixing a continuous reinforcing bar (7) to the end of a vertically-oriented cast-in dowel (2), which device is configured as a wire clip (1) made of a bent piece of wire of length (L) made of at least partially spring-elastic metal, the wire clip (1) being configured with a primary turning bend (3) through an angle (α) of approximately 90° to 180° for receiving the cast-in dowel (2) on one side, with legs (5, 5') disposed mirror-symmetrically with respect to the plane (4) bisecting said angle, each leg (5, 5') forming a secondary turning bend (6, 6') through an angle (β) of approximately 90° to 360° disposed transversely to the primary turning bend (3), for receiving on one side the reinforcing bar (7) disposed substantially perpendicularly to the cast-in dowel (2), a clip-over hook (8, 8') angled transversely to the primary turning bend (3) being formed on the end of each leg (5, 5'), which hook (8, 8') is configured to engage resiliently in a positive and non-positive manner in a radially outer end region (9) of a radial widening (10) of the end of the cast-in dowel (2), and a tertiary turning bend (11, 11') through an angle (γ) of 90° to 270° being arranged between the secondary turning bend (6, 6') and the clip-over hook (8, 8'), characterised in that in each leg (5, 5') a quaternary turning bend (12, 12') through an angle (δ) of 90° to 180° is arranged between the tertiary turning bend (11, 11') and the clip-over hook (8, 8') parallel to the secondary turning bend (6, 6').
  2. Quick-coupling device according to Claim 1, characterised in that the secondary turning bend (6, 6') is configured with an angle (β) of 90° to 180°.
  3. Quick-coupling device as claimed in Claim 1, characterised in that the tertiary turning bend (11, 11') is formed parallel to the primary turning bend (3), optionally in a direction towards the plane (4) bisecting the angle.
