Definitions

  • the present invention relates to a. Attachment profile for increasing the flexural rigidity of a profile half used in a composite profile for windows, doors or the like.
  • the invention further relates to a composite profile for windows, doors or the like, said composite profile having a first profile half, for example an outer shell, a second profile half, for example, an inner shell, and at least one insulating web, which is positively connected on both sides with the two profile halves and thus put the two profile halves together.
  • This so-called bimetallic effect occurs in a thermally separated composite profile whenever one of the two profile halves (inner or outer shell) of a Temperature increase is exposed. Characterized in that the thermally separated composite profile is heated on one side, a longitudinal expansion of the heated profile half occurs, resulting in a shear stress between the two profile halves of the composite profile. If in the composite profile for joining the two profile halves a so-called “shear-resistant composite” is used leads - due to the shear strength of the composite on the one hand and achieved with the insulating thermal separation on the other hand - occurring in one-sided heating of the composite profile shear stress to a deflection of the composite profile.
  • Heat sources are, for example, temperature differences between the inside of the room and the outside air (in winter operation) or the solar radiation on the outside (in summer mode) and the associated heating of the outer shell by absorption of solar energy.
  • the resulting change in shape of the composite profile always acts as a curvature to the warmer side and affects the function of the window or the door, the frames were made from the composite profile.
  • the deflection resulting from one-sided heating may adversely affect the tightness and the closing function of the locks.
  • the deflection is even so great that the sliding door is wedged and can no longer properly open or close.
  • the deflection is sometimes so great that the balancing effect of the existing sealing systems can no longer close the resulting gap.
  • the deflection caused by temperature differences between the outer and the inner metal profile of the composite profile, also causes the proposed lock a door under tension. There is a risk that the door or the window can no longer be properly closed or can not be opened.
  • the effect of the bimetallic effect namely the thermal bulging or deformation of the composite profile
  • the known solutions are generally based on the knowledge, the two profile profiles forming the composite profile (inner or outer shell) To connect by means of a sliding insulating bar.
  • the two profile halves are substantially independent of each other, so that the thermally separated composite profile can absorb shear stresses to a certain extent.
  • a composite profile consisting of an outer and an inner profile half known. These profile halves are interconnected via a plurality of interposed insulating bars, said insulating bars are formed as connecting the profile halves hard plastic webs.
  • Such an insulation composite fulfills the purpose of insulation and thus prevents or reduces heat flow from inside to outside in winter or from outside to inside in summer.
  • the known composite profile is also able to absorb shear stresses to some extent, thus reducing the impact of the bimetallic effect.
  • the publication FR 2 861 746 A relates to a thermally insulated composite profile consisting of a first profile half and a second profile half, wherein these two profile halves are spaced apart and connected to each other by means of two insulating webs.
  • a Provide reinforcement which is a plate which is fastened by means of screws to the outer profile.
  • This reinforcement is made of a material having a modulus of elasticity different from the modulus of elasticity of aluminum.
  • the present invention is based on the problem that the known from the prior art designs to avoid occurring due to the bimetallic deflection can be realized only with relatively high effort, since in the previously known solutions special insulating bars must be used, which a not completely shear-resistant connection of the two profile halves to ensure.
  • special insulating bars must be used, which a not completely shear-resistant connection of the two profile halves to ensure.
  • the known solutions are generally not suitable to subsequently provide an already assembled composite profile with a measure with which the bending occurring due to the bimetallic effect can be reduced or prevented.
  • the object of a composite profile as it is for example in the FR 2 861 764 A1 is described in such a way that the effects of the bimetallic effect, namely occurring due to a temperature difference between the outer and inner profile half bulge of the composite profile, effectively avoided or reduced with an easy to implement, but effective and particularly easy to use solution can be.
  • an attachment profile which is arranged on the outside of the first or second profile half (inner and outer shell) and extends in the longitudinal direction of the profile half, said attachment profile over at least two spaced apart in the longitudinal direction of the attachment profile attachment points with the profile half play connected is.
  • the invention is based on the finding that the bending stiffness of the profile half of the composite profile, with which the attachment profile is connected, can be improved by increasing the area moment of inertia of this profile half, which counteracts buckling of the entire composite profile due to the bimetallic effect.
  • the area moment of inertia - also referred to as the second-degree surface torque - together with the modulus of elasticity is a measure of the stiffness of a flat cross section against bending and depends exclusively on the geometrically given cross section of the body.
  • this profile half is increased by attaching an attachment profile to one of the two profile halves of the composite profile, the area moment of inertia and thus also the bending stiffness of this profile half increase. If the two profile halves of the composite profile are assembled in a shear-resistant composite, this measure also leads directly to an increase in the bending stiffness of the entire composite profile.
  • the attachment profile should run almost over the entire height of the corresponding profile half, thus reinforcing the associated profile half in a particularly effective manner.
  • the attachment profile is only partially arranged on the corresponding profile half.
  • the solution according to the invention provides a measure for reducing or avoiding the bulging of the composite profile that occurs due to the bimetallic effect indicated, which is also attachable to the composite profile later. Accordingly, already manufactured composite profiles can be retrofitted without much effort.
  • the attachment profile has a first profile body extending in the longitudinal direction of the attachment profile and having a substantially rectangular or U-shaped cross-sectional shape.
  • Such cross-sectional shapes are particularly effective on the one hand with respect to the moment of inertia and on the other hand with regard to the total amount of material to be used to increase the bending stiffness of the profile half, on which the attachment profile is mounted, and by the bimetallic effect caused bulge of the composite profile counteract.
  • the profile body of the attachment profile has a different cross-sectional shape, such as a T-shaped or a double-T-shaped cross-sectional shape.
  • the first profile body in cross-section has a contact side in contact with the outside of the corresponding profile half, whose length is preferably less than or equal to the depth of the profile body.
  • the depth of the first profile body forming the attachment profile greater than or equal to the distance between the first and the second profile half is to stiffen the entire composite profile accordingly, which counteracts caused by unilateral increase in temperature deflection of the composite profile.
  • the depth of the profile body is slightly smaller than the distance between the two assembled to the composite profile profile halves. For the increase in bending stiffness, it is essentially important that the depth of the profile body essentially corresponds to the distance between these profile halves:
  • the attachment profile further comprises a second profile body also extending in the longitudinal direction of the attachment profile, which on a side surface in addition to the already mentioned first profile body adjacent the first profile body and having a cross-sectional shape, which is adapted to the application of the composite profile in a window-door or façade system accordingly.
  • a cross-sectional shaping for the second profile body offers a substantially L-shaped shape, wherein the one leg of the second profile body rests against the side surface of the first profile body and the other leg of the second profile body rests on the outside of the profile half of the composite profile.
  • the second profiled body can also serve as a pull handle, if the flexural rigidity of, for example, the longitudinal spar of a sliding door is reinforced with the attachment profile.
  • the attachment profile composed of the two profile bodies terminates substantially flush with the profile half and optionally other profiles or other devices arranged on the composite profile. Accordingly, for the cross-sectional shape of the second profile body if necessary and depending on the application under certain circumstances, to choose a different from the aforementioned L-shaped cross-sectional shape cross-sectional shape.
  • the attachment profile is composed of the first and second profile body
  • the first and second profile body are formed in one piece. This reduces the processing steps required to make the attachment profile.
  • this advantageously achieves that the second profile body of the attachment profile also contributes to increasing the flexural rigidity of the composite profile.
  • the depth of the attachment profile can thus be selected correspondingly smaller.
  • the attachment profile should run almost over the entire height of the profile half in order to effectively increase the flexural rigidity of the composite profile, it is preferred that the attachment profile has a recess portion arranged between an upper and a lower portion of the attachment profile, in which the outside of the profile half of the composite profile is substantially exposed, so that the accessibility to, for example, a handle of an integrated or recorded in the composite profile locking mechanism is still given.

Rather, it is of course also conceivable that corresponding attachment profiles are also mounted on the outer sides of both profile halves, thus effectively reduce the effects of the bimetallic effect or can avoid completely in both winter operation and in summer operation. If attachment profiles are attached to both sides of the composite profile, the depth of each attachment profile can be reduced accordingly. In such a case, it is usually sufficient that the depth of the externally mounted on the composite profile attachment section and the depth of the inside of the composite profile mounted attachment profile together are greater than or equal to the same distance as the distance between the first and second profile half.
