Definitions

  • the present invention relates to a hollow profile for securing objects and formed of a flat material, with the elongate hollow profile having two, spaced from each other and extending in a longitudinal direction of the hollow profile, first side walls, two, spaced from each other, second side walls extending in the longitudinal direction of the hollow profile and transverse to a plane the first side walls lie in, with the first and second side walls defining together a substantially rectangular cross-section, and with at least one trough having two opposite trough walls extending in the longitudinal direction of the hollow profile and parallel to each other, and a trough bottom extending between the trough walls.
  • Hollow profiles of the type described above are used, e.g., for supporting objects which are secured thereto with thread rods, or for supporting other profiles.
  • an elongate hollow profile of a mounting system has grooves or troughs in which a connection element to which a hollow profile can be connected, is guided.
  • a connection element to which a hollow profile can be connected is guided.
  • it is formed of one or several sheet metal components. Such a profile is characterized by a high bearing capacity and a small empty weight.
  • U.S. Pat. No. 3,224,154 discloses an elongate hollow profile formed of several sheet metal components and which, dependent on the application, is formed of several folded sections. Two opposite side walls of this hollow profile are provided each with a trough the trough walls of which are inclined to the trough bottom at an angle of about 45°.
  • the drawback of the hollow profile disclosed in U.S. Pat. No. 3,224,154 consists in its low torsional stiffness.
  • the trough in this hollow profile has either a trapezoidal cross-section which provides little guidance in the longitudinal direction of the profile and in the transverse direction, or a rectangular profile which insures guidance of the connection element but further reduces torsional stiffless of the hollow profile.
  • an object of the present invention is to provide a hollow profile formed of a flat material and having a high torsional stiffness.
  • a further object of the present invention is to provide a hollow profile formed of a flat material and having a small empty weight.
  • Another object of the present invention is to provide a hollow profile formed of a flat material and providing a good guidance in and transverse to the longitudinal direction of the hollow profile.
  • the at least one trough is formed of at least one of the second side walls and has a substantially U-shaped cross-section with two bent regions, with each bent region being formed between the trough bottom and a respective longitudinal web forming a respective one of the two trough walls.
  • the two first side walls each has a receiving region which a respective one of the two bent regions of the at least one trough flatly abuts.
  • the trough according to the present invention has a U-shaped cross-section that provides for good guidance, in and transverse to the longitudinal direction of the hollow profile, of a connection element for, e.g., mounting of one or more other hollow profiles or of other parts such, e.g., brackets. Because the at least one second wall abuts the receiving regions of the first side walls, the trough does not affect the rectangular shape of the hollow profile cross-section. Therefore, the inventive hollow profile insures a high torsional stiffness in comparison with the known hollow profile with a trough.
  • bent regions which are formed between the trough bottom and the opposite side walls of the trough completely abut the receiving regions of the first side walls of the hollow profile, without any noticeable clearance therebetween.
  • a bent region is defined by a length of the second side wall that lies between a trough wall-forming longitudinal web, which tangentially adjoins the bending radius, and the tough bottom.
  • the flat support provides for a better introduction of forces than a linear or punctual support.
  • the inventive hollow profile can be aligned vertically or horizontally with reference to the X-axis of its cross-section, which improves its static characteristics in comparison with known hollow profiles.
  • the bent region abuts the receiving region in form of an onion peel. Because of the shape of the receiving region of the first side wall of the hollow profile and because of the flat contact between the bent region of the trough and the receiving region, sliding of the supportable surface relative to the supporting surface is prevented.
  • the inventive hollow profile is preferably formed of a sheet metal, with the free edges being welded or soldered with each other to form a closed hollow profile.
  • the free edges of the folded metal sheet can also be connected by being glued to each other.
  • a hollow profile should, e.g., have different material characteristics of the first side walls and the second side wall, different initial material can be used for forming the first and second side walls, respectively, with the free edges of adjoining sections, e.g., of side wall being connected with each other.
  • the hollow profile has two trough formed by both second side walls respectively. Both troughs have a substantially U-shaped cross-section with two bent regions. Each of the first side walls has two, spaced from each other receiving regions which respective bent regions of the two troughs flatly abuts.
  • an axially symmetrical hollow profile is formed, which provides, in particular in a mounting system, for a plurality of different orientation of the hollow profile, increasing its application possibilities.
  • the bent regions are adjoined, at at least one of their sides, by bearing regions that flatly abut respective support regions of the respective first side walls. With such increased contact region between the first and second side walls, high forces can be transmitted therebetween.
  • respective bearing regions are provided at both ends of the bent regions. It is particularly advantageous when the thickness of a trough wall-forming longitudinal web of the second side wall is doubled, in comparison with the thickness of material, by folding. This leg of the U-shaped second side wall section extends in the longitudinal direction of the hollow profile.
  • the bent regions and the adjoining them bearing regions abut the respective receiving regions in form of onion peels. With such shape of a hollow profile troughs, sliding of the supportable surfaces relative to the supporting surfaces is prevented to the most possible extent even when high loads are applied to the hollow profile.
  • the cross-webs serve for supporting the inventive profile on an intersecting hollow profile or similar supports, e.g., for placing the inventive hollow profile on a constructional component.
  • the cross-webs provide, in comparison with a linear support which is provided by longitudinal trough side wall-forming webs, an increased bearing surface, which reduces, e.g., linear or point loads in the contact points at which the hollow profile is supported. It should be pointed out that with deep troughs and, correspondingly, high trough walls, the legs, e.g., of the U-shaped second side wall can collapse under a load if a high load is applied to the hollow profile.
  • the thickness of the cross-web amounts to from two to six times of the thickness of the material the hollow profile is formed of.
  • the torsional forces, which are absorbed by the hollow profile are substantially absorbed by the rectangular cross-section of the hollow profile and by the contact regions between the first and second side walls, so that the thickness of the cross-webs in addition to a preferable double thickness, can have a greater thickness value than the double thickness of the material.
  • At least one of the two second side walls can be provided with a plurality of opening for extending fastening means therethrough.
  • these openings are uniformly formed and are arranged at the same distance from each other.
  • the openings are provided on both opposite second side walls. Because the second side walls abut the first side walls at least regionwise, the first side walls support the second side walls and, therefore, the second side walls become only slightly deformed during tightening with fastening means passing through the openings.
  • At least one of the first side walls of the hollow profile is also provided with openings through which fastening means can extend.
  • these openings are uniformly formed and are arranged at the same distance from each other.
  • the openings are provided on both opposite first side walls. Because the first side walls abut the second side walls regionwise, the second side walls support the first side walls and, therefore, the first side walls become only slightly deformed during tightening with fastening means passing through these openings.
  • a distance between the cross-webs, which are provided at the free ends of the trough walls-forming webs, approximately corresponds to a distance between two receiving regions of a second side wall.
  • a second inventive profile can be pivoted by 90° with respect to a first inventive profile and be secured to the first profile, with the cross-webs lying on a flat section of one of the first side walls of the first hollow profile.
  • At least one of the first two side walls has at least one further trough extending in the longitudinal direction of the hollow profile.
  • the width of this trough corresponds to the width of the trough formed by the second side wall. Therefore, a connection element can be mounted on all four outer sides of the inventive profile.

  • the hollow profile 1 has two, spaced from each other first side walls 2 which extend in the longitudinal direction L of the hollow profile, and two, spaced from each other, second side walls 3 which extend transverse to a plane in which the first side walls 2 lie.
  • the first side walls 2 and the second side walls 3 form a rectangular cross-section having a width b and a height h.
  • the static characteristics of the hollow profile 1 are defined substantially by the foregoing dimensions of the hollow profile 1 .
  • Two U-shaped cross-sections of the two second side walls 3 form, respectively, two troughs 4 in the hollow profile 1 .
  • the legs of the U-shaped cross-section of the second side wall 3 form two longitudinal webs 5 which extend in the longitudinal direction L of the hollow profile 1 and define trough walls.

  • first side walls 2 there are formed, respectively, two receiving regions 7 into which the second side walls 3 , together with its bent regions 8 between the trough walls or longitudinal webs 5 and the trough bottom 6 , should completely and flatly fit.
  • the second side walls 3 because of the support of the bent regions 8 in the receiving regions 7 of the first side walls 2 , are deformed only insignificantly.
