Definitions

  • the invention relates to a hollow chamber profile made of polymer material, in the hollow chamber of which a reinforcing element is arranged and which is improved in terms of its flexural rigidity and elongation.
  • Hollow chamber profiles are widely used in various fields. In large quantities, these are manufactured as window profiles, roller shutter profiles, cover profiles and ornamental profiles.
  • a known application also relates to slats, which are arranged as sun visors / window panels on windows, where they act as light and / or privacy. These panels are also known as folding shutters.
  • reinforcing elements are arranged in the hollow chamber of the profiles, which are in contact with the wall of the hollow chamber of the profile and depending on the design increase the flexural rigidity and / or limit or reduce the thermal expansion of the profile. These reinforcing elements are also referred to as reinforcing profiles.
  • the DE 295 13 102 U1 discloses a reinforcing profile in the hollow chamber of a window profile on projecting into the hollow chamber spacer webs, emanating from the walls bounding the hollow chamber, and so to establish contact between the reinforcing profile and window profile, which has an advantageous effect on the flexural rigidity of the thus equipped hollow chamber profile.
  • Window profiles are produced in various designs and to complete the respective systems in a variety of profile cross sections. Almost without exception, these are hollow chamber profiles. Window construction profiles are assembled into frame arrangements. They carry the glass pane and thus high loads, which also result in unfavorable boundary conditions, such as high wind, in large forces to be guided, result. The stiffening of the hollow chamber profiles is therefore necessary and known, it is accomplished by inserting metal elements in the hollow chambers of the profiles.
  • a disadvantage of the known techniques for reinforcing hollow chamber profiles is that the insertion is difficult and therefore associated with great expense. It is also possible to damage the hollow chamber profile during insertion of the reinforcing element. All this requires that the insertion of such elements is associated with a lot of effort and thus also costs in no insignificant amount.
  • the invention is therefore based on the object to modify a hollow chamber profile so that an easy insertion of a reinforcing element is possible in the hollow chamber, wherein the reinforcing element is securely fixed after insertion and the reinforcing element without restriction improves the flexural rigidity and elongation of the hollow chamber profile.
  • the walls or sections of the walls which delimit the hollow chamber in the interior of a hollow-chamber profile are to be interpreted as reversibly yielding during the introduction of the reinforcing element, that is to say they offer little resistance to the introduction itself. After the introduction of the reinforcing element, these largely return to their original shape and thus clamp the inserted reinforcing element and ensure that no unintentional slipping or sliding away can take place.
  • the reinforcing element is then fixed in particular non-positively in the hollow chamber and can advantageously improve the bending stiffness and elongation of the profile.
  • At least one wall of the hollow chamber profile is designed so that the determination of the reinforcing element is made possible by clamping.
  • Another possibility is to arrange a clamping element on the wall of the hollow chamber profile.
  • clamping element in the form of a integrally formed on the wall spring tongue, which clamps the object under bias.
  • the invention proposes to provide at least one resilient element, which protrudes from a wall of the hollow chamber in the hollow chamber, and is formed integrally therewith.
  • the resilient element may be a spring tongue or a clamping spring, which applies a spring force that can be used for fixing the reinforcing element in the hollow chamber of the profile.
  • the resilient element is preferably designed so that it applies a spring force in the direction of the reinforcing element in order to set this against slipping and sliding away and thus secure.
  • the resilient element is preferably arranged so that the reinforcing element in the hollow chamber of the profile under the influence of the spring force of the resilient element is pressed in sections against an opposite wall delimiting the hollow chamber.
  • the hollow chamber profile can be reversibly deformed in the cross section of the hollow chamber by a force which does not result from the insertion of the reinforcing element, and the reinforcing element can be inserted.
  • the force can for example be applied in sections from the outside of the profile, whereby the deformation takes place.
  • the reinforcing element is arranged in the hollow chamber of the profile and fixed in a clamping manner, then it has a favorable effect on the bending stiffness and the longitudinal extent of the profile.
  • the reinforcing element may have an outer contour which is formed in profile substantially complementary to the inner contour of the hollow chamber.
  • the reinforcing element bears resiliently against at least two inner walls of the hollow chamber which are approximately opposite each other and is supported at least in sections on these inner walls, whereby the reinforcement of the hollow profile is achieved.
  • the clamping element can be designed such that at least one wall of the hollow chamber profile delimiting the hollow chamber is designed such that this wall can be reversibly transferred from a first state to a second state by an externally applied force, thereby resulting in a change in cross section of the hollow chamber comes that a reinforcing element can be easily inserted.
  • the second state of the profile is characterized in that by a reversible change in shape of the profile, the cross section of the hollow chamber is at least partially enlarged and thus offers the possibility that the reinforcing element can be easily inserted.
  • the profile After removal of the externally applied force, the profile reversibly returns to the first state and defines the inserted reinforcing element by clamping. Slipping or sliding away of the reinforcing element is reliably prevented in this way.
  • the hollow chamber profile can optionally be acted upon by a force from the outside, wherein the spring element recedes a piece and allows the insertion of the reinforcing element.
  • Another possibility is to introduce the reinforcing profile in the hollow chamber against the resistance of the spring element, overcoming the initial static friction. Once the insertion process is completed, the static friction between spring element and reinforcing element and the displacement or slippage is thus prevented.
  • the spring element which protrudes into the hollow chamber can also be supplemented so that on the spring element and the reinforcing element mutually corresponding interlocking elements, such as a latching lug and correspondingly shaped counterparts, which are designed as recesses in a corresponding surface of the reinforcing element, are provided.
  • This embodiment of the invention can also be applied to the already described special designs of the walls bounding the hollow chamber, by the walls and the reinforcing element corresponding latching elements are assigned, which engage with each other so that a displacement of the reinforcing element in the hollow chamber is even better prevented.
  • the reinforcing element can also be fixed in the hollow chamber of the profile by screwing.
  • the reinforcing element is designed so that material selection and wall thickness are matched to the screwing process.
  • the reinforcing element By screwing the reinforcing element in the hollow chamber, the reinforcing element is fixed immovably in the hollow chamber.
  • a hollow chamber profile is shown in cross-section, in the hollow chamber, a reinforcing element is arranged, wherein the reinforcing element by two opposite the hollow chamber bounding walls, each of which convexly curved towards the chamber convexly curved and designed in these sections, is determined by clamping.
  • a reinforcing profile (4) is arranged such that two walls (3a, c) clamp the reinforcing profile (4), in that these walls (3a, c) are partially in abutment with the reinforcing element (4).
  • the walls (3a, c) face each other and act with a force on the reinforcing element (4).
  • the forces transmitted through the walls (3a, c) to the reinforcing element (4) act against each other.
  • the reinforcing element (4) is thereby securely fixed in the hollow chamber (2) and secured against lateral slippage / displacement.
  • the hollow chamber profile can also be designed so that only a wall cambered towards the chamber curved and designed in sections projecting into it, wherein the clamping of this wall is then communicated through the reinforcing element to a wall that can be designed differently.
  • Fig. 2 shows a hollow chamber profile in cross section, in the hollow chamber, a reinforcing element is arranged, which is fixed by clamping two opposing the hollow chamber bounding each accordion-like walls.
  • a reinforcing profile (4) is arranged such that two walls (3b, d) clamp the reinforcing profile (4), in that these walls (3b, d) are partially in abutment with the reinforcing element (4).
  • the walls (3b, d) face each other and act with a force on the reinforcing element (4). ).
  • the forces transmitted through the walls (3b, d) to the reinforcing element (4) act against each other.
  • the reinforcing element (4) is thereby securely fixed in the hollow chamber (2) and secured against lateral slippage / displacement.
  • a reinforcing element is arranged, which is defined by a spring tongue, which is integrally formed with the wall and protrudes into the hollow chamber.
  • a reinforcing element (4) is arranged such that a spring tongue (5) is integrally formed on a wall (3c). which determines the reinforcing profile (4) by clamping, by the spring tongue (5) partially applied to the reinforcing element (4), this applied with a force and it sets so.
  • the reinforcing element (4) is supported for this purpose on the opposite wall (3a), which is designed here in a cambered shape, and is thereby securely fixed in the hollow chamber (2) and secured against lateral slippage / displacement.
  • a plurality of, in particular also differently designed spring tongues can be provided. But it can also be provided a differently shaped clamping spring.
  • the hollow chamber profiles provided with the reinforcing element can also be cut to a specific length without the reinforcing element arranged in the profile being displaced laterally.
  • the technique according to the invention makes it possible to easily and quickly access such equipped profiles in large quantities.
