    The invention relates to a connector for hollow profiles.
    In the manufacture of components made of profiles, in particular hollow profiles, such as frames or grids, a connection of several profiles is often required, for example, for their extension or for the formation of corner or T-joints.
    Reliable and cost-effective joining of profiles continues to be achieved by welding. However, welding processes are not suitable for every material and leave behind seams which can be a potential weak point and have to be reworked for structural or aesthetic reasons. In the case of powder-coated components, joining by means of welding is by no means desirable since this will destroy the powder coating. Further difficulties may also occur in practice in corner joints, which deviate from a rectangular corner joint, or in T-joints.
    Corner connectors have been proposed as an alternative to joining hollow profiles. Such corner connectors are described for example in DE 20 2010 010 045 Ul, DE 21 59 971 and AT 514 974 Al. These corner connectors have in common that at least two clamping parts or clamping legs are provided which are pressed by means of a spreading means, such as a screw or a displaceable spreading piece, against two opposite inner sides of hollow profiles. In this way, a positive connection between the clamping parts or clamping legs of the corner connector and two opposite inner sides of the hollow profiles is formed.
    The object of the invention is to provide an improved connector for hollow profiles, which allows a weld-like strength. The connector according to the invention should also be able to be applied without an externally visible or barely visible attachment.
    The object of the invention is achieved by a connector for hollow profiles, which consists of two parts and comprises a spreading means, wherein the two parts of the connector in their cross section respectively correspond to the circumference of a baseline open trapezium with two legs and a top. When the parts are inserted into the hollow profile, they are arranged with respect to one another such that the upper sides face each other and the legs extend with their open ends into the inner edges of the hollow profile, wherein at least on the upper side and in the regions adjacent to the upper side a receptacle for the transverse to the longitudinal axis of the respective parts to be arranged spreading means is provided.
    The connector according to the invention ensures for the connection of the hollow profiles a strength which corresponds to that of a weld or a bond. Nevertheless, the connection of the hollow profiles, in contrast to a weld or gluing can be solved if necessary again. Another advantage over the known connectors is further that the connector comprises a small number of parts and can be produced by simple methods without the need for special tools erfoderlich. For example, the connector may be made by a stamping process and all materials known for the production of hollow sections.
    Due to the special arrangement of the legs, the open ends of which after insertion into the hollow profile in the inner edges, very high forces are possible in these areas. As a result, a uniform pressure on all four sides of the hollow profile is achieved without in addition to the central wall of the hollow profiled a special force is exerted. By a uniform design of the legs, a flush alignment of the hollow profile connection is achieved.
    As spreading screws are used, which is preferably self-tapping screws.
    Another embodiment of the connector according to the invention for connecting two hollow profiles at an angle is characterized in that the parts consist of two mutually arranged at an angle sections, wherein in each section at least one receptacle is provided for the spreading. Preferably, the sections are arranged at a right angle of 90 ° to each other to connect two hollow profiles, which are mitred in the usual way, at a right angle to each other.
    Another preferred embodiment of the connector according to the invention is used for connecting hollow profiles in the form of a T-piece.
    For this purpose, in a part of the connector according to the invention, which consists of two at an angle, preferably at a right angle to each other arranged sections, provided in the region of the angle, another portion of two connector elements, which connector elements in their cross section in each case also to the circumference of an the baseline open trapezoidal with two legs and a top and are arranged to each other such that the tops face each other and the legs with their open ends in the inner edges of the hollow section, when the connector is inserted into the hollow profile, wherein in the connector elements At least one receptacle for a spreading means to be arranged transversely to the longitudinal axis of the elements is provided in each case at least one receptacle for the upper sides and the regions of the legs adjoining the upper sides. The further section extends away from a plane that runs parallel to the plane of the upper side of the first two sections and is preferably perpendicular thereto.
    Preferably, the open ends of the legs, regardless of the specific embodiment of the connector according to the invention a complementary to the inner edge of the hollow profile shape, whereby the power transmission is further improved.
    The connector according to the invention is further illustrated by the attached figures of preferred embodiments, without thereby limiting the invention.
    That's it
    Figure 1 is a perspective view of a connector according to the invention for the connection of hollow profiles at a right angle.

    Fig. 4 is a front view of the connector shown in Fig. 1; Fig. 5 is a view of one of the two parts of the connector shown in Fig. 1, seen from the side of the legs;
    6 shows a section through a receptacle for the spreading; and
    Fig. 7 is a perspective view of another embodiment of a erfindungsgenmäßen connector for producing a hollow profile connection in the form of a tee.
    Referring to Fig. 1, a connector 1 according to the invention comprises two parts 2, 2 'whose cross-section each has the shape of a trapezoid open at the baseline, with two legs 3, 3' and a top 4, 4 '. The embodiment shown has two sections arranged at right angles to each other. The legs 3, 3 'are uniform. The illustrated embodiment of the connector 1 is provided for connecting two hollow profiles at a right angle, as shown in Fig. 2. For connection, the connector is inserted into a hollow profile 5 by either the hollow profile 5 is pushed over the connector 1 or the connector 1 is inserted into the hollow section 5. To form a right angle, two hollow sections 5, 5 'are used, which are mitred at the ends which are intended to form the angle. After assembly of the hollow sections 5, 5 'and the connector 1 are provided in the two parts 2, 2' of the connector 1 receptacles 6, 6 'for the spreading 7 congruent with openings 8, 8' in the hollow sections 5, 5 ', arranged, which serve openings for the introduction of spreading 7.
