Definitions

  • the invention relates to a profile piece according to the preamble of claim 1.
  • Profile pieces or bars are known to produce modularly constructed, optionally demountable profile bar structures, such as lightweight walls, exhibition stands, partitions, shoring, transport routes and the like from them.
  • profiled bars are preferably made of an aluminum alloy or of plastic.
  • An adaptation of the profile bars or a profile bar construction by bending the profile pieces to a buckle usually fails due to the low elongation at break s of the aluminum alloy used, which is due to the relatively large cross-sectional dimensions and far from the neutral axis, along which no bending stresses removed, arranged surface elements easily Damage, in particular to cracks in the material, since even at low bends of the profile pieces, in particular on the walls contributing to the stiffness of the outer walls expansions and compressions result, which are beyond the tolerable limits for the materials.
  • a surgical instrument with a rigid element which has a bent region.
  • a surgical device extends coaxially in the rigid element. It has a relatively flexible region in the bent region to transmit actuating forces to a surgical tool located at the tip of the surgical device.
  • the flexible area consists of a tube or a rod and is made flexible by means of staggered cuts in all directions.
  • EP 0 393 834 B1 discloses an atherectomy system with a flexible rotary catheter which can be elastically bent along its longitudinal axis.
  • the rotary catheter comprises a tubular skeleton consisting of individual ring elements and the ring elements interconnecting connecting elements.
  • the tubular skeleton is made of a rolled, stamped stainless steel sheet. In this case, the tubular skeleton can be bent elastically between two adjacent ring elements.
  • DE 199 10 312 A1 discloses an expanded metal grid with predetermined breaking points for use as plaster base, spacers, packaging for spherical objects, drying grid or reinforcing material for laminating work.
  • a disadvantage of the elastically or plastically deformable and bendable elements described is that they are not suitable for producing mechanically loadable profiled bar structures, such as lightweight walls, exhibition stands, dividing walls, shoring, transport routes and the like from them.
  • a disadvantage of the described profile bar constructions is that no arbitrary curvatures, vaults or tracks can be reproduced with the profile pieces from which such constructions are assembled.
  • the invention has for its object to propose a profile piece for the production of profiled bar constructions or transport routes of profiles, which is at least partially adaptable to any bends or bumps.
  • the invention is in any case realized when it comes to profile pieces for the production of profiled bar constructions, preferably extruded profiles of rigid material, which have at least one elastically and / or reversibly deformable desired bending part.
  • profile pieces for the production of profiled bar constructions, preferably extruded profiles of rigid material, which have at least one elastically and / or reversibly deformable desired bending part.
  • Profile pieces of the type in question here typically have a substantially rectangular or circular cross section, wherein in the outer walls extending in the longitudinal direction of the profile piece, outwardly open grooves are formed, which on the one hand a considerable material savings and on the other hand, a high strength of the Profl Committees is reached.
  • the cross-sectional profile can also be honeycomb-shaped or square and have any, preferably regular shape.
  • the grooves also serve, for example, to connect several profile pieces to any profile bar construction by means of sliding blocks insertable into the grooves.
  • Such profiled rod constructions may serve any purpose, for example as mentioned above, such as the manufacture of exhibition stands, lightweight walls, partitions, shoring, transport routes or of special machine constructions of a plurality of similar profile pieces which can be connected to one another by means of the grooves and fastening elements which can be arranged therein.
  • workpiece carrier can be arranged, for example, designed as carrying or mounting aids running transport routes in workshops, by means of which depends on the ceiling components, for example, from a warehouse to a mounting location on the roller bearings transport elements along a predetermined path can be transported hanging.
  • workpiece carrier can be arranged, for example, designed as carrying or mounting aids running transport routes in workshops, by means of which depends on the ceiling components, for example, from a warehouse to a mounting location on the roller bearings transport elements along a predetermined path can be transported hanging.
  • the profile piece behaves in its bending area like an elastically or at least reversibly deformable body, which can be adapted to the requirements without further ado.
  • an adaptation of the profile piece can be achieved to the predetermined path so readily.
  • the incisions preferably extend from the one longitudinal side in each case at most to the walls forming the base of the grooves arranged on the other longitudinal side.
  • the profile bar according to the invention also has the advantage over the prior art that it can be adapted in sections by the incisions to any curvatures or bends, without the maximum permissible elongation ⁇ of the material from which the profile bar is made being exceeded is because in the lying through the incisions located in the outer part of the cross-sectional profile areas no bending stresses and thus no strains occur, whereas in the remaining inner, not severed by the incisions areas because of the only small distance to the neutral axis only small, tolerable strains occur for the materials used.
  • the profile bar has a substantially square cross-sectional profile with longitudinally arranged on its longitudinal sides arranged rear gripping, the incisions from the respective opposite longitudinal side in each case at most up to the bottom of the Schugreifungen forming, facing away from the back grips Walls are enough.
  • Another advantageous embodiment of the invention provides that the profile bar on each of its longitudinal sides along at least one limited portion each offset to one another in the longitudinal direction arranged incisions, so that the profile bar in this section is bendable in any direction. It is also possible to make the cuts circular. In both cases, the incisions extend from the one longitudinal side at most each to the outer wall of the opposite longitudinal side.
  • the profile bar is made of a metallic material, preferably an aluminum alloy.
  • An additional advantageous embodiment of the invention provides that the profile bar is made of a plastic.
  • a profiled bar 1 having a substantially square cross-sectional profile 2 is provided with incisions 4 for generating a bending zone 8 by means of a circular saw blade 3 along a section 9.
  • the incisions 4 are arranged on two opposite longitudinal sides 5, wherein the incisions 4 extend to the neutral axis in the middle of the profiled bar 1 and are arranged offset to each other on the longitudinal sides 5, so that there is no danger to sever the profile bar 1.
  • the profile bar 1 has on its longitudinal sides 5 Hintergreifept 6, which of Walls 7 are limited. When inserting the incisions 4, care must be taken that an incision 4 in each case does not extend deeper than to the respective wall 7 of the opposite longitudinal side 5, since otherwise the profile bar 1 is severed.
  • FIGS. 4 to 7 how local bending zones 8 are produced by the sections 4 arranged in sections, within which the profiled bar 1 is bendable in one plane and thus adaptable to any curvatures or bends. It is conceivable to arrange a plurality of bending zones 8 on a profiled bar 1, just as it is conceivable to provide the notches 4 not only from two longitudinal sides 5 but all around alternately from each longitudinal side 5, so that a bend in any plane is possible.
  • the bending radius can be influenced or limited by varying the cutting width, cutting depth and number of cuts 4 per unit length. Generally it is about the adaptation of any lines in the room.
  • the profiled bar 1 can also be bent or rotated about the axial direction of the neutral central axis of the profiled bar 1 (torsion). In the field of saw cuts the profile has lost 1 in stiffness.
  • the profile 1, as can be seen in FIGS. 8 to 11, can be stiffened again, at least within the bending zones 8 provided with the incisions 4, by suitable longitudinal strips 10, so that the bending remains stable within the intended radius.
  • the bending of the profile bar 1 takes place once.
  • the longitudinal strips 10 serve to fix the profile bar 1 in the selected bending direction.
  • the longitudinal strips 10 include, for example, profile rails made of plastic or metal.
  • the profile 1 can be stiffened using bending soft longitudinal strips 10 by this opposite to the inside and on the outside of the curvature, for example by plug, Adhesive, rivet, screw or the like in a region with a small bending radius, and once in an opposite region with a large bending radius for the duration of use of such a profile bar construction are fixed.
  • the longitudinal strips 10 are preferably arranged in the outer edge chamfer of the profiles, for example in the region of the undercuts 6 forming the grooves.
  • the profile 1 is stiffened again in the region of the bend.
  • the longitudinal strips 10 are claimed as a function of the bending stress of the profile bar 1 in the longitudinal direction to pressure or train.
  • veneers 12 can be clipped into the back grips 6 of the profile bar 1 according to the invention, for example to cover the incisions 4 in the area of the local bending zones 8. This is in addition to a visual enhancement especially a reduction in the risk of injury when dealing with profiled bar structures produced from such profiled bars 1.
  • Such a veneer increases the dimensional stability of the profiled bar 1 in the region of the bending zones 8.
  • the veneer 12 has for fastening in the back grips 6 resiliently arranged locking lugs 13, which on the longitudinal sides 5 of the profile bar 1 axially extending on the longitudinal sides 5 of the profile bar 1 extending, the 7 limited by the walls behind the backs 6 grooves as shown in Figure 14 initially penetratefedem, and then ausfedem again as shown in Figure 15 in the assembled state.
  • the veneers 12 are clipped into the rear grips 6 of the profile 1 by means of the latching lugs 13.
  • the veneers 12 are preferably made flexible.
  • the veneers consist of an elastic material.
  • the veneers 12 and the locking lugs 13 are preferably made in one piece.
  • Several veneers 12 can be arranged along a profile bar.
  • the veneers can be arranged at a profile bar construction on all grooves, which need not be kept free for constructive purposes.
  • the invention is particularly applicable industrially in the field of production of profiled bars and the production of profiled bar constructions and transport routes.
