Definitions

  • the invention relates to a frame system according to the preamble of claim 1.
  • a triangular support of the type mentioned which has three belts and in which the brackets are flat, triangular plates with a central recess, these plates having holes in the area of their corners through which the belts are inserted will. These plates are alternately inclined at a positive and negative angle with respect to the belts, adjacent plates touching each other on their top or base sides.
  • This triangular support represents a special form of a so-called belt support and does not provide for the possibility of connecting several such supports to a frame.
  • DE-A-22 36 086 describes a frame system that uses similar triangular supports.
  • the belts are designed as double rods running parallel to one another for the purpose of fastening means such as, for example, between these double rods. Screw on elbows.
  • Some of the brackets are inclined in relation to the belts in order to increase the stability, as is known in the case of truss girders.
  • the front brackets are at a right angle to the straps, so that a connection to other lattice girders can only be made obtuse.
  • additional straps in the form of double bars are provided for lateral attachment, each of which is connected to the side bisector of the bracket. A total of six belts in the form of double bars are provided there. This requires a lot of material, increases the weight of the lattice girders and gives them a confusing appearance.
  • the object of the invention is to use the lattice girders mentioned at the outset to create a frame system in which abutting lattice girders can be connected to one another as simply as possible.
  • a frame system with an easy-to-assemble frame can be created. These frames also have an aesthetic appearance and allow electrical cables or the like to be routed inside.
  • the frame system is also very flexible, such that a large variety of different frames can be expanded with basic elements.
  • This frame system enables two basic types of connection of the lattice girders, namely the frontal connection, in which the two frontal (triangular) brackets lie opposite one another, and a connection of the end face of a lattice girder to a "side" of another lattice girder.
  • two adjacent brackets of the lattice girder, to which it is connected laterally also form a triangle, which lies opposite the front triangle of the other lattice girder.
  • the interconnected lattice girders form an angle of 90 °, the "connecting surface" lying exactly in the bisector of the connection.
  • connection lies in the fact that two adjacent brackets each span a regular pyramid, the pyramid surfaces preferably being inclined at 45 ° with respect to the central perpendicular of the pyramid.
  • the belts are alternately tilted by 180 ° in the longitudinal direction, i.e. nested pyramids in front.
  • Each "pyramid surface" can serve as a connection surface.
  • the triangles spanning the pyramid surface have a base angle of 54.74 ° or more precisely from atn Vi: Accordingly, the apex angle of the triangles is then 70.53 ° or more exactly 180-2.atn V2. ' This applies to the 45 ° tilt angle.
  • the individual brackets are preferably made of bent wire, the wire ends being butt-bonded, preferably welded. So you only need a bracket shape that can be manufactured on a machine in large stock.
  • the connection of the brackets to the belts, which are preferably elongated wire rods, is preferably carried out by welding, which can be carried out particularly easily by electro-resistance welding.
  • the invention provides three basic variants (each with several sub-variants) for connecting lattice girders.
  • abutting brackets are connected directly to one another, for example by clamping or tensioning elements or by welding.
  • plate-shaped structures are attached to the “flat” to be connected, these plates then being connected to one another, for example screwed, by means of a bayonet catch or the like.
  • connection means such as Screws can be inserted.
  • Areas of application of the present invention are in particular shelves, chairs, tables or floor lamps and brackets, for example for suspended ceiling structures, for example for hanging lamps, loudspeakers or decorations on the ceilings of larger halls, and also as cable ducts or for accommodating desk silos.
  • FIG. 1 There two lattice girders 1 and 2 are connected to one another, the longitudinal axes 3 and 4 of lattice girders 1 and 2 being perpendicular to one another.
  • Each lattice girder has three longitudinal bars or straps 5, 6, and 7 or 5 ', 6', 7 ', which are connected to one another by brackets 8 to 16 or 8'-12'.
  • the brackets are designed here as flat plates with a central recess, which makes flat, isosceles.
  • Triangles are formed. Details are explained in more detail in connection with FIG. 3.
  • the two belts 5 and 6 or 5 'and 6' lie in one plane and are connected to each other by the base side (e.g. 17) of the bracket.
  • adjacent brackets form a pyramid.
  • the base of the pyramid is formed by the base sides (eg 17) of the triangles 8 and 9 and the corresponding sections of the straps 5 and 6.
  • the respectively identical "side surfaces” of the pyramid are formed by the triangles spanned by the sides of the two brackets 8 and 9 and by the surfaces spanned between the two triangles 8 and 9. It is important that all four sides of the pyramid are identical. This enables the lateral connection, as shown here between the brackets 12 and 13 of the lattice girder 1 and the bracket 8 'of the lattice girder.
  • the "pyramid surface” formed by the bracket 8 ' fits exactly to the pyramid surface lying between the brackets 12 and 13. So it is a regular pyramid with quadra table area.
  • the brackets each have holes 23, 24 and 25 in the region of their corners 20, 21 and 22, through which the belts 5, 6 and 7 are inserted.
  • the straps 5, 6 and 7 are additionally fastened in the holes, for example by gluing or welding.
  • the lattice girders 1 and 2 are each cut off here in the plane formed by the brackets 10 and 8 ', the brackets 10 and 8' lying flat on one another here.
  • the central axes 3 and 4 are thus perpendicular to one another.
  • the two brackets 10 and 8 ' are fastened to one another by connecting elements 26 (cf. FIG. 4). 2 that the individual stirrups (e.g. 10 'and 11') (seen in the side projection) form an angle of 45 ° with respect to the central axis.
  • the orientation of the angle is opposite, so that an angle of + 45 ° and -45 ° is alternately formed.
  • the adjacent peaks of neighboring triangles form an angle of 90 °.
  • brackets have a central, here triangular recess 27a.
  • brackets 10 and 8 ' can be clamped by connecting elements 26.
  • the legs 17, 18 and 19 can also have holes so that the brackets 10 and 8 'can be screwed together.
  • the legs can also be welded together.
  • FIG. 4 shows an example of connecting elements 26.
  • This connecting piece here has an approximately circular plan view with two diametrically opposite and inwardly extending recesses 27 and 28 which open into oblong holes 29 and 30 lying transversely to them, so that a central web 31 is provided remains.
  • the connecting elements 26 are of course elastic, with one side 17, 18 and 19 of the brackets to be connected to one another first being inserted into one of the recesses 27 and 28 and then the connecting element 26 being rotated so that the leg 17, 18 or 19 lies in the elongated hole 29 or 30.
  • the straps 5, 6 and 7 are arranged in the same way as in the embodiment of FIG. 1.
  • the brackets 8, 9, 10 and 11 are designed here as curved, one-piece wire brackets, corresponding to the shape of a "triangle".
  • the corners 20, 21 and 22 of the brackets are rounded, so that the tips of the triangles are "resolved”.
  • the central axes of the upstanding legs (e.g. 18 and 19) of brackets with their tips (22) adjoining each other (e.g. 8 and 9 or 10 and 11) form the side edges of the pyramids. 5 these center lines 32 and 33 intersect at an angle of 90 °. The intersection lies above the upper belt 7 and exactly above the center line 3.
  • the center lines 33 and 36 or 32 and 37 of the legs of the stirrups 9 and 10 also intersect at an angle of 90 °, the intersection point here being outside the lattice girder.
  • the base sides of the brackets 9 and 10 are here also parallel and at a distance from one another, the spacing of the base sides of the brackets 9 and 10 being equal to the distance between the “tips” of the brackets 8 and 9. If one connects the intersection points of lines 32 and 37 as well as 33 and 36 with each other by a line 38 and draws parallel lines 34 and 39 as well as vertical lines 40 and 41 running through the mentioned intersection points, these lines form the edges of the pyramid.
  • a first pyramid thus has the following surfaces: A first surface is spanned by lines 32, 33 and 34.
  • a second pyramid side is spanned by lines 32, 33 and 38, the bracket 9 lying in the plane formed thereby.
  • the third surface is formed by lines 32, 33 and 40, one leg of each of the brackets 8 and 9 lying in the plane formed thereby.
  • the fourth side is formed by lines 32, 33 and 41, the other legs of the brackets 8 and 9 lying on the plane formed thereby.
  • the pyramid base area is formed by lines 34, 38, 40 and 41. All pyramid surfaces are identical.
  • a pyramid upside down compared to the pyramid described is formed by the brackets 9 and 10.
  • the basis of this further pyramid are the lines 39, 40, 41, and a line 42 which is parallel to the line 39 and is formed by the "tip" of the bracket 10.
  • the pyramid surface in question for a lateral connection is then formed here by lines 32 and 37 and a line 35 running above the plane of the drawing parallel to the center line 3.
  • the other surface is formed accordingly by lines 33 and 36 and the line mentioned.
  • FIG. 6 A side view of the lattice girder of FIG. 5 is shown in FIG. 6. This view illustrates the arrangement under alternate angles of + 45 ° and -45 ° of the brackets 8, 9 ... compared to the belts 6 and 7 and the right angle between adjacent brackets 8 and 9, 9 and 10 or 8 and 11. Also here again clearly recognizable that the tips of the triangles formed by the brackets are resolved, so that the bracket axes intersect "outside" of the lattice girder.
  • Fig. 7 shows an end view or a section along the line VII-VII of Fig. 6.
  • the bracket 9 shown here consists of a one-piece, bent wire, the free ends of which are butt welded together.
  • the base angles between the legs 17 and 18 or 18 and 19 are 45 °, while the acute angle between the legs 18 and 19 is 90 °.
  • these angles result (in the projection) by tilting a triangle with the base angle of atn V2 and the acute angle of 180 -2 atn V2 by 45 ° (corresponding to FIG. 6).
  • the lower straps 5 and 6 are offset from the corner of the triangles by a distance inwards, while the upper belt 7 rests on the inside of the bracket 9 at the apex.
  • the radii of curvature at the corners of the triangle are chosen so that there is the same distance between the tips of adjacent triangles (e.g. 8 and 9 in Fig. 5) and between the base sides of adjacent triangles (e.g. 9 and 10 in Fig. 5).
  • FIG. 8 branches two lattice girders arranged parallel to one another in a plan view similar to FIG. 5.
  • the belts 5, 6, 5 'and 6' lie in one plane, while the belts 7 and 7 'lie in a parallel plane lying above them.
  • Adjacent brackets e.g. 8 and 8 ', 9 and 9', 10 and 10 'and 11 and 11' meet here. Due to the radii of curvature on the base sides of the triangles and the distance of the lower straps from the corners of the triangles, a "free" space is created in the example of FIG. 8 between the adjacent corners of the brackets 9, 9 ', 10 and 10' which a vertical rod 43 can be inserted.
  • This rod can support the lattice structure from below or can be used to pull the lattice structure from the ceiling.
  • the adjacent lattice girders can be connected to one another by cross bars 44.
  • the crossbar 44 of FIG. 8 lies on the belts 7 and 7 'and is inserted at a distance at the tip of the adjoining brackets 8' and 9 'or 8 and 9.
  • a similar transverse rod could also be used there, which then connects the straps 5 ', 6', 5 and 6 to one another and runs parallel to the base sides of the triangles 9 'and 10' as well as 9 and 10.
  • suspended ceiling structures can be produced, to which, for example, lighting fixtures, loudspeakers or the like are attached.
  • FIG. 9 shows a perspective view obliquely from above of a lateral connection of two lattice girders 1 and 2 in the embodiment of FIGS. 5 to 7 similar to the illustration in FIG. 1.
  • the end face of lattice girder 2 is here on a "pyramid side" of lattice girder 1 connected.
  • FIGS. 10 and 11 show a connecting element of a first basic variant, in which adjacent brackets are clamped by clamping elements. Two mutually opposite and parallel sections of brackets 9 and 9 'are to be connected here.
  • An approximately oval body 80 is used as the connecting element 80, which has an opening 81 on one side. The width of this opening 81 corresponds to at least twice the diameter of the bracket 9 or 9 '.
  • the connecting element 80 can also be imagined as a plate, the two lateral ends of which are bent up in the same direction, namely with a circular bending radius, the inside bending radius being adapted to the radius of the brackets 9 and 9 '.
  • the brackets 9 and 9 ' are first brought close together for assembly so that they can be inserted together through the opening 81. Then they are moved laterally outwards from each other. Then a wedge piece 82 is pushed between the two brackets 9 and 9 'so that the two brackets 9 and 9' are pressed apart until they abut laterally on the "bent-up" sides of the connecting element.
  • the wedge piece 82 can be T-shaped in the cross section of FIG. 10, so that the cross leg 83 closes the opening 81.
  • the lower edges 84 of the wedge piece can be slightly beveled. Otherwise, the effective wedge surfaces 85 of the wedge piece are parallel to one another in order to ensure a secure hold.
  • the width of the wedge piece 82 is slightly larger than the free distance between the two brackets 9 and 9 ', so that material deformation and thus perfect clamping of the individual parts takes place.
  • the wedge piece 82 can, for example, be pressed in with pliers.
  • the connecting element 80 and the wedge piece 82 can be made of steel; but it is also possible to make only the connecting element 80 from steel and the wedge piece 82 from plastic.
  • the basic variant of the connecting elements of FIGS. 10 and 11 is the preferred embodiment according to the invention, since it is easy to manufacture and assemble and has an aesthetic appearance.
  • the connecting element of FIGS. 10 and 11 is the least conspicuous in a finished shelf.
  • connecting elements 45 are used, which are made up of two mirror-symmetrical to each other built parts 46 and 47 exist. Both elements each have two recesses 48 and 49 or 48 'and 49', which are adapted to the contour of the bracket, and are opposite each other. Through bores 51 and 52 or 51 'are provided in a central section 50 or 50' and are aligned with one another. Screws or, for example, rivets can be inserted through these bores in order to connect the two parts 46 and 47 to one another, so that brackets to be connected are then held between the recesses 48 and 48 'or 49 and 49'.
  • FIGS. 14 to 19, as well as 23, 24 and 26 Another basic fastening variant is shown in FIGS. 14 to 19, as well as 23, 24 and 26.
  • plate-shaped connecting elements are in principle attached to the "pyramid side", the opposite plates being connected to one another, for example by screwing, welding or a bayonet lock.
  • An end connection (similar to FIG. 2) is shown in FIG. 17.
  • plates 53 and 54 are applied, which in this case protrude toward the end face beyond the brackets 9 and 9' and, for example, rest thereon, as can be seen more clearly from FIG.
  • the plates 53 and 54 are hexagons, the outer edges of which are adapted to the contour of the brackets 9 and 9 '.
  • the plates 53 have a central, here circular (here an ellipse in the projection) recess 55, the recesses of the two plates 53 and 54 being opposite one another.
  • the two plates 53 and 54 are screwed to one another only via this recess 55, specifically by means of a threaded sleeve corresponding to FIG. 19.
  • This threaded sleeve 56 has a base body 57 with an external thread 58, the diameter of this external thread 58 the diameter of the recess 55 is adapted so that the threaded sleeve can be inserted through the recess 55.
  • the base body 57 has a central bore 59, which enables cables or the like to be guided through the connection point. At one end, the base body 57 has a circumferential collar 60, which comes to a stop when screwing in on one of the plates 53 and 54. The attachment then takes place via a threaded nut 61 which is screwed onto the external thread 58 to such an extent that it comes to a stop against the other plate 54 or 53 and thus screws the two plates together.
  • both lattice girders do not have to be specifically fixed in the direction of rotation about their central axis. Rather, the "stable" position results when the frame is loaded even if both central axes lie in one plane and form an angle of 90 °.
  • an end plate 53 according to FIGS. 16 or 23 can also be used.
  • a hexagonal plate with a central, circular recess 55 is provided, but here there are additional screw holes 62 so that contacting plates can be screwed together by three bolts.
  • the plate rests on the end face of the bracket 9.

  • This plate is a triangle here, the top of which rests on the belt 7.
  • the base side of this triangle engages behind the lower belt 5 with a bent tab 66, which can be clearly seen from FIG. 15.
