Definitions

  • the invention relates to an engagement bushing for the connection of a panel including a support core disposed between first and second cover sheets to a third element by means of a mounting element, wherein the bushing is provided with a through-bore for receiving the mounting element mounted to the third element.
  • Panels with support cores are often also called sandwich panels, honeycomb panels or lightweight construction panels. All types of panels used in furniture construction have generally cover sheets consisting of thin wood-chip plates or hard fiber boards.
  • the sandwich panels include as center layer or, respectively, support core, for example, polyurethane foam or polystyrene.
  • support core for example, polyurethane foam or polystyrene.
  • honeycomb plates intermediate layers, often corrugated web inserts or so-called expanded honeycomb structures, are used which have a weight of less than 500 kg/m 3 . If, for the intermediate layer, no fire-retardant aluminum foams or foamed glass is used, the raw density is below 350 kg/m 3 . For comparison, the raw density of a non-layered wood particle board is about 600-750 kg/m 3 .
  • the passage includes a first section which extends through the first cover plate and the support layer and a second section of smaller diameter extending through the second cover plate for accommodating the mounting element, an expansion sleeve is disposed in the first section so as to abut the second cover plate and the part of the expansion sleeve disposed in the first cover plate is radially expandable so that it can be expanded into radial engagement with the first cover plate while it is axially engaged with the second cover plate when the lightweight construction panel is engaged by the mounting element with the other structure.
  • the mounting element expands the sleeve in the opening of the first cover plate by means of a truncated cone-like or pyramid-shaped head or by means of an intermediate truncated cone or pyramid-shaped wedge element by an elastic or plastic deformation of the sleeve at least over a certain area thereof.
  • the sleeve comprises an essentially tubular base body which has a planar lower and a truncated-cone-shaped upper front area wherein the imaginary tip of the truncated cone-shaped front area is disposed in the interior of the sleeve on the centerline of the sleeve and in the area of the truncated cone-shaped front, the sleeve is radially elastic or is plastically deformable and/or longitudinally slotted.
  • a sleeve is provided by which hardware fixtures or other furniture parts can be firmly and reliably mounted to lightweight construction panels.
  • the hardware fixtures and the furniture components are mounted to the panels by means of through-screws, for example, machine screws or wood screws. After installation, the individual through-screw abuts with its head directly or indirectly the lightweight construction panel whereas the supportive thread part of the through-screw is threaded into the fixture part or respectively, the furniture part.
  • nails or rivets may be used in place of the screws.

  • a mounting means 90 such as a screw is inserted in order to thread it into the thread 152 of a third element 150 , for example, a handle.
  • FIG. 3 shows the lightweight construction panel 100 with a handle 150 mounted thereto.
  • FIG. 3 shows, in an enlarged view, a detail of FIG. 1 , wherein the expansion sleeve 10 is shown disposed in the lightweight construction panel 100 , see also FIG. 11 .
  • the lightweight construction panel 100 comprises two cover sheets or plates 101 and 111 and a support core 121 disposed therebetween.
  • Each cover plate 101 , 111 consists in the shown embodiment of a thin flake board.
  • the upper cover plate 101 has an opening 105 for example in the form of a relatively large bore whereas the lower cover plate 111 includes a smaller bore 115 .
  • the diameter of the opening 105 is for example about twice as large as the diameter of the lower bore 115 .
  • the support core 121 is for example in the form of a foam core. It includes an opening 125 for example in the form of a bore whose diameter corresponds to the diameter of the relatively large bore 105 . All bores 105 , 125 , 115 have a common centerline 9 .

  • the lightweight panel 100 has a wall thickness of 15.5 mm.
  • Each cover plate 101 , 111 has a thickness of 2.95 mm.
  • the panel may include a honeycomb core.
  • the thickness of such a lightweight panel 100 is between 14 and 90 mm.
  • the cover plates 101 , 111 which, in the shown example, have the same thickness, may have a thickness in the range of 0.4 to 10 mm.
  • the lightweight construction panels may also include several different support core layers 121 and the different support core layers may be separated by additional cover plates.
  • the present invention is also suitable for flake board panels which include less dense intermediate layers.
  • the still undeformed expansion sleeve 10 is, as shown in FIGS. 2 and 11 , a tubular base body 11 , which consists of a plastically deformable plastic material for example a polyoxymethylene.
  • the application-based main deformation direction extends transverse to the expansion sleeve center line 9 . In the longitudinal direction, that is, parallel to the center line 9 , the expansion sleeve 10 is, at least essentially, nondeformable.
  • the expansion sleeve 10 has a planar lower front area 15 and a truncated cone-shaped upper front face area 12 .
  • the latter is in the form of a conical counter bore.
  • the upper front face area 12 has for example a cone-angle of 90° as it is used for commercial screws 90 with flat heads 91 .
  • the tip of the conical counter bore is disposed on the expansion sleeve center line 9 within the expansion sleeve passage 16 .
  • the wall thickness of the base body 11 is, depending on the embodiment, between 2 and 10 millimeters.
  • the expansion sleeve 10 is so inserted into a bore formed into the lightweight construction panel 100 that its lower end face 113 abuts the lower cover plate 111 in a so-called support zone 114 , see FIG. 4 .
  • the upper edge 13 of the expansion sleeve 10 is then disposed essentially level with the outer surface 102 of the upper cover plate 101 .
  • the edge 13 is shown for example slightly below the plane, that is, the level of the outer surface 102 of the upper cover plate 101 .
  • the lower end face 15 of the expansion sleeve 10 may be provided with a cement film or another adhesive coating.
  • the coating may be a cement coating, for example, a micro-sphere coating whose cementing effect is activated only by pressing the end face 15 onto the inner surface 113 of the second cover plate ( 111 ).
  • the expansion sleeve is provided in the upper area of its outer wall, that is, in the area where it is in contact with the upper cover plate 101 , once it is installed, with one or several engagement structures.
  • the ribs 21 in this case have the cross-section of a triangular with sides of equal length.
  • the maximum diameter of the ribs 21 is for example a few tenths of a millimeter larger than the inner diameter of the bore 105 .
  • the flanks of the ribs 21 enclose for example an angle of 30°.
  • the ribs 21 in this case have a pitch distance of for example 0.7 mm.
  • the expansion sleeve 10 is—after insertion—firmly retained in the lightweight construction panel 100 even without an application of cement material to the lower end face thereof.
  • the expansion sleeve includes for example two ribs 22 with different flank angles.
  • the lower flank is inclined with respect to the center line 9 by about 20° whereas the respective upper flanks are inclined with respect to the center line 9 by an angle of 90°.
  • Both ribs 22 are arranged closely adjacent each other. The flank arrangement shown here facilitates the installation of the expansion sleeve.
  • knobs 24 are shown instead of ribs 21 , 22 .
  • the knobs 24 are arranged for example in two rows on the outer contour of the sleeve next to each other. In circumferential direction, they are spaced from one another by a distance corresponding to about two- to five times the knob foot width. However, the knobs 24 may also be arranged on a zig-zag pattern. Each knob 24 has a semicircular cross-section. Other knob shapes such as pyramid-, cone-, or truncated cone-shapes are also possible.
  • the variant according to FIGS. 16 and 17 shows a plurality of longitudinal ribs 26 arranged on the outer contour of the sleeve.
  • the longitudinal ribs 26 are in accordance with the shown embodiment about twice as long as the upper cover plate is thick. For example, fifteen longitudinal ribs 26 are equidistantly distributed over the circumference.
  • Each longitudinal rib 26 has for example a cross-section which is defined by lines of equal length, and which increases linearly toward the top so as to reach its maximum at the upper edge 13 . This expansion sleeve presses small notches into the wall of the bore 105 so as to prevent rotation of the expansion sleeve.
  • the sleeves may have multi-angled or polygonal outer contours. Also, elliptical cross-sections are possible. Similar shapes may be provided for the opening 16 of the expansion sleeve 10 .
  • the bore 16 may also be provided with an internal thread.
  • FIGS. 3 and 4 show an expanded expansion sleeve in the form as it is present after installation in a lightweight construction panel 100 and the attachment of a third element 150 in the form of a handle.
  • the expansion sleeve is inserted into the bore 130 and the handle 150 is held with its threaded bore disposed in front of the bore 115 of the lower cover plate 111 .
  • a flat head screw 90 is inserted into the bore 16 of the expansion sleeve and is pushed through the bore 15 and finally screwed into the threaded bore 152 of the handle 150 .
  • the expansion sleeve is pressed on one hand against the lower cover plate 111 and on the other hand, the upper area of the expansion sleeve is expanded transversely to the center line 9 .
  • the expansion effect results from the cooperation between the cone-shaped end face 12 and the shape of the flat head 92 of the flat head screw.
  • the conical upper end face 12 of the expansion sleeve 10 and the screw head form a slide wedge drive.
  • the handle 150 is held in the lightweight construction panel at the same time in two different ways: On one hand, the lower cover plate 111 is clamped between the expansion sleeve and the handle 150 as the clamping sleeve is subjected to an axial pressure. On the other hand, the upper part of the expansion sleeve is radially expanded into firm contact with the walls of the bore 105 while the ribs 21 for example bite into the wall of the bore 105 .
  • the handle When now the handle is subjected to pull forces, the lower as well as the upper cover plates 111 , 101 each accommodate part of the pulling force.
  • the handle When, on the other hand, the handle is subjected to forces effective transverse to the longitudinal direction of the screw connection, support is provided for the screw in transverse direction via the thread 95 at the bore 115 and via the screw head 91 at the upper end of the expansion sleeve 10 and consequently at the bore 105 .
  • FIGS. 5 to 7 show an expansion sleeve by which a lightweight construction panel 106 is connected to a transversely extending particle board 160 which forms the third element in a so-called corner joint.
  • a transverse bore 168 is provided in the particle board 160 and a transverse bolt 165 with a transverse threaded bore 166 is disposed in the transverse bore 162 .

  • the web 35 breaks apart when the expansion sleeve and the wedge element 31 are axially compressed, see FIG. 11 .
  • the breaking apart occurs when the screw 90 is tightened.
  • the annular front face 33 of the wedge element 31 abuts the upper front face area 12 and spreads the upper part of the base body 11 apart, see FIG. 11 .
