Connector for double glazing frame section members

The invention relates to a connector for double window frame profiles according to the preamble of the main claim.

In detail, the invention relates to an edge connection connector for double window-frame sections have a base body, on which a plurality of projecting this strip-shaped fins are arranged and thus a Edge connection piece for front mounting an internal Spacer rung at a for insulating necessary spacing frame.

From the prior art it is known, hollow frame profiles to use or hollow spacing profiles to multi-pane insulating glass produce or double windows. In this case, the Frame hollow profile and cut to length by means of the connector to a Frame molded on which then the front side and back in each case a glass plate is bonded. The hollow section frame is filled with a hygroscopic agent to the humidity from the enclosed between the panes to remove air.

In such connectors, it is necessary that this simple mountable and reliable in the frame hollow profile can be anchored. It makes both the type of anchor and the question of the fatigue of the plastic material a crucial role.

The invention is based on the object, a connector of the to provide the aforementioned type, which with a simple design and simple, cost-effective producibility well anchored is and ensures a high level of operational safety.

According to the invention the object is achieved by the combination of features solved the main claim, the subclaims show further advantageous embodiments of the invention.

According to the invention it is thus provided that a base plate extend out of three mutually parallel legs, which are spaced apart, wherein the two outer of Leg the lamellae are arranged pointing outwards and wherein the central leg with means for introducing a Fastener is provided.

The connector according to the invention thus makes it possible, in a particularly easily center marks of double window frame profiles produce. As will be described will be, the center marks can each two mutually comprise parallel frame profiles, or a so-called Wiener rung. Such Viennese glazing has a total relatively large cross section which so dimensioned is how the desired center cross. In Vienna Rung can on the installation of two parallel frame profiles be waived. This results in a simpler Assembly.

The connector according to the invention is therefore universally usable and can for different double window constructions be used. This decrease storage costs, because by means of a single connector diverse constructions can be created.

According to the invention in a preferred embodiment, that the distance between two adjacent fins in a range is from 1.5 to 2.0 mm.

By inventively provided spacing between the individual Lamella is in the connector, a sufficiently high number of segments feasible to secure retention and anchoring to ensure.

Furthermore offers the dimensioning according to the invention of the distances of the lamellae the possibility of the connector in the Frame hollow profile is inserted, reliable with this to dig. Since the various embodiments of Frame hollow profiles on its inside A diversity embodied have raised or rough areas, for example, by indentations, weld beads or the like is, the connector according to the invention universally for different Frame hollow profiles used.

It is particularly advantageous when the distance between adjacent slats is 1.75 mm. It is to be understood that also each Kind of intermediate values ​​from the above-mentioned range between 1.5 and 2.0 mm can be favorable, for example, values ​​of 1.55, 1.65, 1.85 and 1.95 mm.

According to the invention it is further provided that the total height the basic body and the lamellae is larger than an associated Inner height of the hollow profile. Hereby, the lamellae forcibly deformed during insertion into the hollow frame profile, whereby the inventively provided wedge effect the lamellae results. The fins hold the connector thus not by frictional force, so as with the from the Prior art prior art connectors is known, but by selectively applied wedging action. This makes it possible individual fabric strips with the areas of the frame hollow profile sure to wedge in which not additional Expressions or the like are. According to thus there is a wedging or clawing of the slats, their effect especially occurs when a pull-out force is applied. Thus, the present invention differ Lamellae of the known from the prior art Embodiments in which the support frictionally and pressing the lamellas against the wall of the hollow profile frame takes place.

In order to promote a secure anchorage for the slat, it is especially advantageous if the free edge of the fin to form a cutting edge is chamfered. This increases the Surface pressure between the fin and the inner wall of Frame hollow profile.

According to the invention, it is furthermore particularly advantageous if the lamellae are arranged so that they are inwardly relative produced in a finished, out of the frame hollow profile Setting extend. The rear sides of the base body can then a secure positioning of the two ends of the frame hollow profiles ensure whereby any type of game excluded can be.

It is particularly advantageous if the insertion length 24 mm is. This means that the basic body substantially is 24 mm long, so that a sufficiently long distance with the Slats can be filled, so that a correspondingly high Number of segments present. The insertion length can also 20 to 30 mm, depending on the dimensioning of the frame hollow profile.

The outer leg is preferably at its the lamellae opposite side with a sawtooth ribbing provided. This also contributes to the holder in and causes a good investment on the frame hollow profile.

By constructing the invention, it is particularly easily possible, the connector with the respective frame sections to join in the base plate. These Connection may be through different fasteners be effected, for example by bolts or clamp-like fastening elements, being shot, or by screws. It proves to be particularly advantageous if the Base plate is provided with a central recess. This central recess serves firstly to guide and Centering of the fastener. On the other hand can the head of the fastener also be settled, as material parts of the frame profile, which by a head the fastener are mitverformt. It arises Thus, a substantially planar outer contour of the frame profile.

To a universal use of the connector according to the invention or the end piece for both the above-mentioned Wiener Sprouts as well as two mutually parallel frame profiles to improve, it is advantageous when the middle leg with the respectively adjacent outer leg via a separable. Strut is connected. The separable strut can when pushed two frame profiles to be cut through in a simple manner. When using a Wiener rung the struts remain exist and strengthen the holding force of the connector.

The middle leg is preferably made of one piece constructed interconnected longitudinal webs and transverse webs, forming a honeycomb or chamber-like structure. This results in a particularly good clamping a Fastener, such as a screw. It is it is particularly favorable when two inner longitudinal webs a distance have, which is substantially equal to the core diameter the fastening element or screw.

The longitudinal webs and transverse webs thus ensure good serve guiding a helical fastener, for centering the screw and allow high tightening force, which in turn to an independent sinking of Screw head, in particular for steel-frame profiles, leads.

The connector according to the invention can thus as a connector, as Anschraubstück both for creating T-sprouts or are used by crosses. This has the advantage, that storage costs are low and that further the connector according to the invention both for different Designs or dimensions of the frame profiles (also is used for the Vienna sprout), wherein the frame profiles different materials, aluminum and steel can be used.

The selection of the plastic material for the connector according to the invention is chosen so that this one hand so tough and elastic is that the connector slightly relevant in the Frame profiles can be inserted, on the other hand, the plastic such a high strength has to as Anschussstück or Anschraubstück to be usable. The plastic is thereby preferred Manner also chosen so that the separable strut both sufficiently stable when using a Wiener rung as also easily separable when sliding of two parallel frame profiles is. The plastic used should be a strength (Yield stress) of 20 to 30 MPa (ISO 527-2), a Elasticity and toughness (impact-resistance) 20-30 KJ / m² at + 23 ° C according to ISO 179/1 eA and a Shore D hardness, have 3-s-value 58-68 ISO 868th It can, for example, a polyolefin material are used.
