Definitions

  • Framework constructions are used in many contexts, and particularly where it is desirable to achieve low weight, while simultaneously maintaining high rigidity and strength.
  • weight of the material itself constitutes a limit, even if extremely lightweight materials, such as carbon fibre, are chosen.
  • Figs. 2, 3, and 4 show in perspective structures that may be built from the beam shown in Fig. 1, i.e., an L-profile, a U-profile, and a box-profile.
  • Fig. 5 similarly shows in perspective one example of a holder, implemented in a frame structure, and a framework design, assembled by means of some of the beams of the invention.
  • Fig. 6 shows a part of the holder of Fig. 5 on a larger scale.
  • Fig. 7 shows in perspective an assembled tube joint.
  • the framework construction according to the invention consists of a framework constructed from beam profiles 11, which may be I, L U, or box profiles, even though other combinations may be contemplated.
  • the beam is constituted by an I-profile 12, the "flanges" 13 of the profile consisting of tubes made, e.g., from carbon fibre, aluminium, titanium, or similar material of low weight, and the "web" 14 is constituted by a sandwich structure consisting, e.g., of a suitable core material, for instance, foamed PVC, and a covering material in the form of a laminate, e.g., carbon fibre.
  • the flanges 13 are connected, in a load bearing manner, to the web 14 in an appropriate way, depending on the materials involved, e.g., through gluing, welding, in connection with extrusion of the profile, or similar.
  • a holder for an object which is to be positioned by a robot in a predetermined position for machining in an automated manufacturing process, or for assembling, e.g., to a chassis in the vehicle industry.
  • the tube joints 21 may suitably be of two kinds, one kind which is threaded onto the tubes from the ends, and one type which is divided in order to be able to be mounted at any position along the length of any of the tubes. In the latter case, a recess 22 is arranged in the web 14 at the position where the tube joint 21 is to be placed.
  • the tube joints are available at least in the most common angles, 15, 30, 45, and 90 degrees, and in the form of joint connections 23 for connecting several, for example four, crosslaid beams.
  • the tube joints are non-rotationally connected to the respective tubes 13 by means of glue, welding or pinch joints or the like.
  • FIG. 5 and 6 illustrates a framework construction in the shape of a frame structure forming a holder 24, also known as a halter, for a constructional component (not shown) to be machined or mounted on another constructional component.
  • the holder 24 is designed with a central joint connection 23, which also forms an attachment point for a robot arm.
  • the joint connection 23 connects four crosslaid I-beams 25, the outer end parts of which are interconnected with a rectangular frame structure consisting of I-beams 26 and 27, positioned opposite to one and other, and L-beams 28 and 29, arranged transverse in relation to the former.
  • attachments 30 are arranged, for retaining the constructional component in question.
  • attachments 31 are arranged for the positioning of the holder in relation to fixed reference points.
  • struts 32 for improved rigidity in the form of simple tubes, may be arranged, on which further attachments may be positioned.
  • the beams 26, 27 and 28, 29 of the frame structure are situated on different levels, but it is of course possible to design branch joints 21 for connection of more than two tubes, e.g., three or four, which may also have different angles.
  • the tube joints 21 may also be designed in such a way that both the tubes 13 and the web 14 can be pushed into them, so that an effective connection of the entire beam is achieved.
