Definitions
- the invention relates to a connecting element for two end regions of box-shaped hollow profiles, in particular spacer hollow profiles in multiple glazing with a base plate and side walls with resilient retaining elements.
- Connecting elements of this type serve to connect end regions of box-shaped hollow profiles to one another by plugging the connecting element and the two end regions together. These can be straight connections or corner connections.
- connection elements are used, for example, in insulating and fire protection laminated glasses in which at least two glass panes are arranged at a distance from one another. The distance between the two glass panes is determined by a spacer hollow profile which is inserted in the area of the circumference of the two glass panes.
- Spacer hollow profiles of this type are produced from metal, for example aluminum or plastic.
- a connecting element of this type is known from DE 34 08 600 A1. It is a connector for hollow profiles, in particular spacer hollow profiles for insulating glass panes.
- the connector described can be used both as a longitudinal connector and as a corner connector.
- the spacer hollow profile has a substantially rectangular cross section, the corner regions being partially beveled.
- various other cross-sectional shapes are also known.
- the connecting element has a U-shaped cross-sectional configuration and is normally punched out of sheet steel and pressed. Both on the base plate and on the side walls of the connecting element, resilient lugs or tabs are punched in and protrude, which act as resilient retaining elements. These resilient retaining elements are directed towards each other on one half of the connecting element.
- the retaining elements are directed in such a way that when the connector is inserted they spring into the cavity of one end of a spacer profile and thus enable the plugging together.
- the retaining elements When the connector and the box-shaped hollow profile are pulled apart, the retaining elements cling to the inner walls of the spacer hollow profile and ensure a non-positive connection.
- Several such retaining elements can be arranged on each half of the connecting element, the innermost retaining element seen from the center of the connecting element also serving as a stop element when the connector is plugged together with one end of the hollow spacer profile. This is to prevent the connecting element from being fully inserted into one end of the hollow spacer profile. The end faces of this connecting element are closed.
- connecting elements are already known from DE 30 37 015 A1, in which the end faces are open. This open arrangement enables the cavities of the connecting element and the spacer hollow profile to be filled with fillers, such as dehumidifiers or fire protection compounds, in the same operation.
- connection element of this type is known from EP A1 283 689.
- the connecting element described here should also be suitable for corner connections such as straight connections of spacer hollow profiles in insulating glass panes.
- the connecting element likewise has retaining elements stamped into the base area and into the side areas, which are bent outwards and are designed to be resilient.
- the connecting elements themselves must be rigid in order to ensure the spring action of the Ensure retention elements.
- this feature does not normally lead to difficulties.
- hollow plastic spacer profiles have also been used for some time.
- the known connecting elements it can now be seen that faults occur again and again.
- One difficulty is that the hollow spacer profiles in the area of the inserted connecting elements are damaged or destroyed.
- the spacer hollow profiles are assembled between the glass panes before they are inserted and then have to be transported or moved.
- the rigid connecting elements now lead to the hollow spacer profiles being bent in the end region of the connecting elements and tearing or breaking.
- the retaining elements which are arranged on the side walls of the connecting element, engage in side wall regions of the spacer hollow profiles, which can be exposed to high bending loads. Due to the notch effect of the grooves, which arise when the connecting elements are pushed into the spacer hollow profiles, the spacer hollow profile can burst under bending loads. Larger manufacturing tolerances, such as can occur, for example, in the case of hollow plastic profiles, or if larger manufacturing tolerances are permitted in the case of hollow metal profiles, can often not be compensated for by the known connecting elements. The non-positive connection between the connecting element and the two end regions of the box-shaped spacer hollow profiles is then no longer guaranteed in every case.
- the side walls of the connecting element are formed so that they are profiled in cross section. This profiling can be achieved by a single or multiple curvature of the side walls or by single or multiple bends or by a combination of bends and bends.
- the profile of the two side walls is chosen such that a first area of each side wall, which connects to the base plate of the connecting element, forms a first spring element and a second area of each side wall, which forms the free end area of this side wall, forms a second spring element.
- the first spring element enables movements of the side walls in a direction approximately parallel to the surface of the base plate and at right angles to the longitudinal axis of the base plate.
- the second spring element enables movements at least in one direction approximately at right angles to the surface of the base plate and to the longitudinal axis of the base plate. This area can also carry out additional movements alone or together with the first spring element, for example in the direction parallel to the surface of the base plate of the connecting element.
- the connecting element is inserted into a hollow profile, the first regions of the two side walls of the connecting element lie at least partially on the two side walls of the hollow profile.
- the base plate of the connecting element lies against a base surface of the hollow profile and the free end regions of the second region of each side wall of the connecting element lie against the top surface of the hollow profile.
- the connecting element Due to the side walls of the connecting element, which are resilient both parallel and at right angles to the base area of the connecting element, an optimal non-positive holding is achieved in the two axial directions transverse to the longitudinal axis.
- the side walls of the connecting element springing in over a relatively wide range enable adaptation to larger tolerances, ie dimensional softening of the cavity of the hollow profiles without reducing the quality of the connection between the connecting element and the hollow profiles.
- the spring travel ranges from 1% to 10% of the height or width of the connecting element.
- connection between the connecting element and the hollow profiles is achieved in that the second areas of the two side walls have a plurality of cutouts which are open towards the free end area and sawtooth-like retaining elements are formed between these cutouts.
- the saw teeth of the left half of the connecting element in the longitudinal direction and the saw teeth of the right half of the connecting element are directed towards each other. This arrangement ensures that the two ends of the two hollow profiles, which are attached to the connecting element and abut each other in the middle of the connecting element, can be easily pushed onto the connecting element, but the opposing saw teeth prevent the two hollow profiles from being pulled apart.
- outwardly directed retaining claws are arranged on the first region of the side walls, which have the advantage that the retaining forces between the side walls of the connecting element and the side walls of the hollow profiles are increased.
- These retention claws are arranged approximately in the contact area between the side walls of the connecting element and the side walls of the hollow profiles. They consist of star-shaped openings which are pressed into the side walls of the connecting element, the tabs of these openings projecting beyond the outer surface of the side walls.
- the connecting element is made from a material from the group of stainless steels and a material thickness is selected which is a maximum of 0.4 mm. This material in this material thickness can be processed and shaped well and a material specification can be selected which has the desired elasticity or spring characteristic. Suitable materials are, for example, chrome nickel steels with a molybdenum additive.
- At least one reinforcing rib is arranged in the base plate of the connecting element over part of the length of the connecting element.
- the shape and length of this rib are dependent on the desired strength or spring properties of the connecting element.
- Several or differently oriented ribs can also be arranged in a manner known per se.
- Another way of influencing the longitudinal and torsional elasticity of the connecting element is to vary the depth of the recesses in the second region of the side walls in relation to the total height of the side walls. The depth of these cutouts is advantageously chosen to be greater than half the total height of the side wall.
- the connecting element according to the invention is primarily suitable for straight connections of two end regions of box-shaped hollow profiles. In an angled form, it can also be used for corner connections of box-shaped hollow profiles.
- the connecting element is angled in the middle in the desired manner in a manner known per se.

- FIG. 4 shows a cross section through Hollow profile with inserted connecting element
- FIG. 5 shows a partial illustration of the connecting element with an enlarged illustration of the lateral retaining claws.
- Fig. 1 shows two end regions of two box-shaped hollow profiles 2, 3, which abut one another at a parting line 35.
- the two hollow profiles 2, 3 are connected by means of a connecting element 1 according to the invention, which engages in the two cavities 36, 37 of the two hollow profiles 2, 3 and positions the two profiles 2, 3 relative to one another.
- the connecting element 1 consists of a base plate 4 and two profiled side walls 5, 6.
- the two side walls 5, 6 consist of two areas 7, 9 and 8, 10.
- the first area 7 closes , 8 of the two side walls 5, 6 on the base plate 4 and the two second areas 9, 10 of the two side walls 5, 6 form the free end areas of the two side walls 5, 6 with the free ends 28, 29.
- the Profiling the cross section of the two side walls 5, 6 has a wavy shape, which is generated by two circular arcs facing each other.
- the first area 7, 8 of the two side walls 5, 6 is curved outwards and in the example shown has a radius of 1.5 mm, for example. This with a total width of the connecting element 1 of approximately 14 mm.
- the second area 9, 10 of the two side walls 5, 6 has an opposite curvature with a radius of approximately 1 mm. The two curvatures merge into one another and the two regions 7 and 9, 10 of the two side walls 5, 6 also interlock and can overlap.
- the connecting element 1, which in 1 and 2 is shown, has a height of about 5 mm in this example shown.
- the width and the height of the connecting element 1 and the profiling of the two side walls 5, 6 depend on the cross-sectional shape of the box-shaped hollow profiles 2, 3 and on the dimensions of the cavities 36, 37 of these hollow profiles 2, 3. This mass can be in a wide range vary and are determined by the hollow profiles known per se.
- the cross section of the two side walls 5, 6 can be profiled by multiple curvatures and / or bends. It is essential when choosing this profiling that the first and second regions 7, 8 or 9, 10 of the two side walls 5, 6 result in the spring elements desired according to the invention.
- the double-curved profile shown in FIG. 2 gives a particularly expedient spring action and is easy to manufacture.
- the first two regions 7, 8 of the two side walls 5, 6 form spring elements which enable movements of the side walls in the direction of the arrows 13 approximately parallel to the surface 11 of the base plate 4 and approximately at right angles to the longitudinal axis 12 of the connecting element 1.
- the second regions 9, 10 of the two side walls 5, 6 form a spring element, which allow at least movements in the direction of the arrow 14, ie approximately at right angles to the surface 11 of the base plate 4 and to the longitudinal axis 12 of the connecting element 1.
- the spring travel available to the two side walls 5, 6 enables one Adaptation to relatively large tolerance ranges of the internal dimensions of the cavities 36, 37 of the two hollow profiles 2, 3. This both in the direction of the width and the height of the connecting element 1, or of the hollow profiles 2, 3. This spring travel is usually in a range between 1% to 10% of the width or height of the connecting element 1 selected.
- the connecting element 1 has a reinforcement in the direction of the longitudinal axis 12 in the central region of the base plate 4. Kungsrippe 27 on.
- the dimensions of this reinforcing rib 27 are determined in a known manner, although other shapes can also be used.
- recesses 21, 22 are arranged in the two side walls 5, 6, which are open towards the free ends 28, 29 of the side walls 5, 6. These recesses 21, 22 determine on the one hand the ability of the connecting element 1 to bend transversely to the longitudinal axis 12 and on the other hand form the spaces between saw teeth 23, 24, which are also parts of the side walls 5, 6.
- the saw teeth 23 of the left half 25 of the connecting element 1 are directed against the parting line 35 and the saw teeth 24 of the right half 26 of the connecting element 1 are also directed in the opposite direction against this parting line 35.
- the depth 34 of the cutouts 21, 22 in the second region 9 , 10 of the side walls 5, 6 is chosen so that it is greater than half the total height of the side walls 5, 6.
- FIG. 3 shows the connecting element 1 in a cross section, the side walls 5, 6 being shown both in the non-installed starting position and in the spring-loaded installation position.
- the spring element which is formed by the first region 7, 8 of the two side walls 5, 6, is displaced by a spring travel 38 in the direction of the arrows 13.
- the second regions 9, 10 of the two side walls 5, 6 form a spring element which enables at least one deflection around the spring travel 39 in the direction of the arrows 14.
- the interaction of the two spring elements, which are formed by the first regions 7, 8 and the second regions 9, 10 of the side walls 5, 6, causes a combination of the deflection of the free ends 28, 29 of the two side walls 5, 6. This The combination causes the spring travel 38, 39 to overlap, so that these free ends 28 move in the direction of the arrows 13 around the spring travel 40 and in the direction of the arrows 14 around the spring travel 39.
- FIG. 4 shows a cross section through the hollow profile 3 with the connecting element 1 inserted.
- the connecting element 1 When the connecting element 1 is inserted into the cavity 36 of the hollow profile 3, the side walls 5, 6 are shown in the region of FIG. set travel 38, 39 and 40 elastically deformed and assume the position shown in Fig. 4.
- Sub-areas 19, 20 of the two side walls 5, 6 abut the side walls 15, 16 of the hollow profile and are pressed against them by the spring action in the first area 7, 8 of the side walls 5, 6.
- the base plate 4 of the connecting element 1 lies against the lower broad side 17 of the hollow profile 3.
- the free ends 28, 29 of the two side walls 5, 6 of the connecting element 1 are pressed by the spring action against the opposite broad side 18 of the hollow profile 3.
- the free ends 28, 29 of the side walls 5, 6 or the edges 42 of the saw teeth 24 claw into the inner surface of this broad side 18.
- the hollow profile 2 or 3 shown in the example is a plastic profile, in which the edges 41, 42 of the saw teeth 23, 24 of the connecting element 1 are pressed into the material as a result of the spring forces.
- Retaining claws 30, 31 are formed on the first regions 7, 8 of the two side walls 5, 6 as additional anchoring means. These retaining claws 30, 31 are also pressed into the material of the side walls 15, 16 of the hollow profiles 2, 3 and, in addition to the non-positive anchoring due to the spring action, form a positive connection between the connecting element 1 and the two hollow profiles 2, 3.
- the retaining claws 30, 31 shown here consist of openings 32 which are produced with a square tool.
- these openings 32 have a star-shaped shape with four lobes 33, which are pressed outwards and protrude beyond the outer surface of the side walls 5, 6.
- Such openings 32 can also have a different shape, in which case a differently shaped tool is used.
- the depth of penetration of the tabs 33, which claw into the side walls 15, 16 of the hollow profiles 3, 4, can be determined precisely since it is determined on the one hand by the spring force of the side walls 5, 6 and on the other hand the maximum depth of penetration through the partial areas 19, 20 of the side walls 5, 6 is determined, which abut the side walls 15, 16 of the hollow profiles 2, 3.
- the retaining elements on the connecting element 1, which are formed by the retaining claws 30, 31 and the edges 41, 42 of the saw teeth 23, 24, can be arranged in a position in which no damaging notch effects of the hollow profiles 2, 3 can occur.
- connecting element 1 can be positioned so that the forces which bring about the non-positive connection between connecting element 1 and hollow profiles 2, 3 act optimally between connecting element 1 and hollow profiles 2, 3.
- the design of the connecting element 1 according to the invention enables the geometric shape to be adapted over a wide range, so that the area of use of this connecting element 1 is possible with practically all known hollow profiles 2, 3 which are used in multiple glazing.
