Definitions

  • the present invention relates to a support frame, in particular a part of a support frame with at least two mitred hollow profiles with at least one inner chamber and at least one corner connector which engages in the hollow profiles with its legs according to the preamble of claim 1.
  • the corner connector can have receptacles for insertable fasteners, by means of which the hollow profiles and the corner connector can be connected, the fasteners being able to be designed as bolts (80) which can be driven into bores in the hollow profiles and into receptacles in the legs of the corner connector, and the bolts in at least one of the Receptacles through which the bolt extends are fixed in a form-fitting manner.
  • the present invention sets itself the task of countering the disadvantages of the prior art and of providing a reliable connection between the corner connector and hollow profiles of a support frame, which overcomes the disadvantages of the prior art.
  • the receptacles are designed as separate/discrete polymer sleeves inserted into the legs of the corner connector, in which at least one recess is provided for the positive reception of the bolts in the leg.
  • the hollow profiles and the corner connectors are connected under pretension in the connected state by means of the bolts, in that the bores of the hollow profiles and the receptacles of the corner connectors are arranged with a partial offset from one another.
  • the polymer sleeves offer the necessary flexibility and elasticity to compensate for an offset between the holes in the hollow profiles and the receptacles on the corner connectors, which allows subsequent correction work on the individual components of the supporting frame can be avoided.
  • an offset between the holes in the hollow profiles and the elastic receptacles can lead to a preload between the bolts and the parts of the support frame in the connected state, which additionally increases the connection strength.
  • the polymer sleeve of one leg has two or more recesses for bolts and/or is formed in one piece.
  • the distance between the recesses in the polymer sleeve can be adapted to the distance between the corresponding holes in the hollow profile.
  • the adjustment can have an offset with respect to the bores, which compresses or pulls apart the body of the polymer sleeve with prestress when the support frame is in the connected state, whereby the positive connection of the hollow profile and corner connector by means of the bolt in the polymer sleeve can be supplemented by or replaced by a friction connection .
  • the polymer sleeve can also serve as a spring element between the corner connector and the hollow profile and can be provided with a pre-adjustable spring constant/spring force, whereby the requirements of the support frame can be adapted depending on the area of application.
  • the spring constant or spring effect of the part of a support frame according to the invention can be determined on the one hand via the selection of the polymer, i.e. the intrinsic material-bound spring constant, as well as via a spring tension of the material of the polymer sleeve by appropriate selection of the distance between the recesses in relation to the distance between the holes in the hollow profile set.
  • a particularly large offset between the receptacles in the corner connector and the corresponding holes in the hollow profile can pre-strengthen the material of the polymer sleeve in a special way and create and/or increase a frictional connection.
  • the offset between the hole(s) in the hollow profile and the at least one recess in the polymer sleeve can preferably be 0.1 mm to 5 mm.
  • the polymer sleeve can be fixed in the leg in a form-fitting and/or force-fitting manner.
  • the polymer sleeve can be elastic and/or allow the bolt to be displaced to compensate for the offset.
  • the sleeve can be designed with a conical outer contour, with a receiving area in the leg of the corner connector for the polymer sleeve corresponding in its inner circumference/inner contour approximately to the outer circumference/outer contour of the polymer sleeve, resulting in a particularly effective fixation in the direction of tapered recess is provided in the corner connector.
  • the polymer sleeve is formed from polyethylene, polypropylene, polyurethane or polyacrylonitrile or a mixture of the aforementioned.
  • the choice of polymer can have a direct influence on the spring constant or the spring effect between the corner connector and the hollow profile.
  • the overall height of the corner connector corresponds to the clear height of the inner chamber in the hollow profile.
  • a separate inner chamber is provided for each leg of the hollow profile.
  • two adjacent hollow profiles can be connected via more than one corner connector. If more than one corner connector is provided, it may be useful to provide the hollow profile with separate inner chambers for each corner connector.
  • the shape of the inner chamber is expediently adapted to each of the corner connectors or its legs.
  • At least one polymer sleeve for adjusting a spring constant for example in its receptacle (10), is arranged interchangeably in this.
  • Different polymer sleeves with different elastic properties can be provided to adapt the corner connector and its resilient connection properties.
  • the inner chamber is adapted to the shape of the leg, in particular the inner chamber surrounds the leg in a form-fitting manner.
  • Figure 1 shows a recording 10 according to the present invention, which can be designed as a polymer sleeve.
  • the receptacle 10 has at least one recess 20, which is designed to receive a connecting bolt for connecting the corner connector and the hollow profile, preferably in a form-fitting manner.
  • the receptacle is designed with more than one recess to accommodate more than one bolt.
  • the shape of the receptacle 10 can be described as bone-shaped or 8-shaped in cross section.
  • the sleeve 10 is preferably designed to extend at least over the length of the bolt to be received and/or preferably to be completely received into the corner connector.
  • recesses 30 or bores 30 can be provided in the material of the receptacle 10, which can locally influence the spring force or spring constant of the receptacle between the bores 30 and the recess 20.
  • a change in the elasticity of the material is influenced in particular along an axis of the recess 20 and bores 30, whereas the elasticity of the material of the receptacle remains significantly unaffected in other areas. This makes it possible to specifically provide different elasticity in different spatial directions transverse to the longitudinal axis of the bolt receptacles 20.
  • Figure 2 shows the corner connector 50 according to the invention with its legs 60 and recesses 70 in which the receptacles 10 can be arranged.
  • the shape of the recesses 70 is preferably adapted in its inner contour to the outer contour of the receptacle 10, whereby the receptacle 10 is in the leg 60 of the Corner connector 50 can be fixed in place.
  • two recesses 20 for bolts are provided in each leg 60 of a corner connector 50.
  • any number of bolts can be provided in corresponding receptacles in each leg.
  • a single receptacle 10 can also be provided for a large number of bolts.
  • Figure 3 shows an exploded view of corner connector 50 with receptacle 10 and bolts 80 that can be provided therein.
  • the bolt 80 is driven into the receptacle 10 or its recesses 20 through holes in a hollow profile.
  • Figure 4 shows an exploded view of a part of a support frame according to the invention, in which two corner connectors 60 are provided in corresponding cavities 92 with inner contours preferably adapted to the outer contour of the leg 60 of the corner connector 50.
  • This allows the corner connector to be inserted into the hollow profile 90 in a stationary manner, preferably in a form-fitting manner.
  • Bores 91 in the hollow profile 90 are preferably adapted to the distance between the recesses 20 in the respective receptacle 10.
  • the distance between the holes 91 which belong to a leg 60 of a corner connector 50, can deviate slightly from the corresponding distance between the recesses 20 of the corresponding receptacle 10, so the holes can be closer or further apart.
  • the polymer material is preferably spread or compressed along the connecting axis of the two holes 91 for one leg of a corner connector, whereby an increased frictional connection can be provided for the connecting fixation of the bolts in the part of the support frame .
  • the receptacles 10 can have an overall conical shape, which tapers towards the interior of the support frame part. This means that the receptacle 10 can be secured in the leg 60 of the corner connector 70 even if the bolt 80 is driven into the receptacle 10 through the bore 91 with high force. An unfavorable displacement of the receptacle 10 deeper into the interior of the corner connector or even out of the corner connector to the opposite side can thereby be counteracted.
  • the part of a support frame or support frame formed in this way with several hollow profiles and corner connectors mounted between them has the essential advantage of a flexible connection between the corner connector and the hollow profile as well as two adjacent hollow profiles. This means that, on the one hand, variances in production can be compensated for, and on the other hand, disadvantageous deformation of the corner connector or its recesses or the hollow profiles can be prevented during tension or pressure, for example along the connecting axis of the corner connector and the carrier/hollow profile.
  • the clamping force and strength of the connection can be adjusted by a defined offset of the bores 91 to the corresponding recesses 20 of the receptacle 10.
  • the connection of two hollow profiles via the corner connector according to the invention has the advantage that the components are at least partially decoupled from one another with regard to the individual tensile and compressive forces on the individual hollow profiles and are at least partially accommodated by the respective polymer body of the receptacle 10.
  • Such a concept for the simple production of a support frame part, which tolerates variants in the production process and at the same time provides hollow profile elements that are decoupled from one another in terms of force, is not known from the prior art.
