Abstract

Structural elements and furniture components are manufactured by positioning laths (13, 14, 15) parallel to each other on a glue-coated panel, whereupon the spaces between the laths are filled with honeycombs (16), preferably of cardboard, or with foam plastic material. Then, a second glue-coated panel is positioned on top of the laths and the honeycombs or foam plastic material, and this unit is glued together under pressure. The unit is thereafter sawn across the laths (13, 14, 15), and the resulting elongated pieces (20) are rotated through 90° about their longitudinal axis and positioned on a third glue-coated panel (18) and covered with a fourth glue-coated panel (19), whereupon the last-mentioned panels (18, 19) are subjected to pressure and glued together. The resulting unit is then sawn (at 22) along and between the elongated pieces (20), such that one obtains bodies which on all sides are covered with panel material and which internally are filled with lath material and honeycomb or foam plastic material (16'), and which are well suited to be used as, for example, table legs. The panels may consist of fibreboard, particle board, veneer, laminate, metal sheet etc., and the laths may be made of wood or particle board.

Description

METHOD OF MANUFACTURING STRUCTURAL ELEMENTS, ESPECIALLY

FURNITURE COMPONENTS

Y*

The present invention relates to a method of manufac- 5 turing structural elements, especially furniture compo¬ nents, such as table legs and table frames etc, in which method a blank is produced by positioning laths of wood, particle board or the like, parallel to each other on one glue-coated flat side of a first panel, the spaces between

10 the laths are filled with honeycombs of cardboard, plas¬ tic or the like, or with foam plastic material, of appro¬ ximately the same height as the laths, and a second glue- coated panel is positioned on top of the laths and the honeycombs or foam plastic material, whereupon the unit

15 thus produced is subjected to pressure and glued together. It is prior art technique to use this method for manufacturing for example doors, the laid-out laths forming the edge surfaces of the door. The resulting product has a satisfactory torsional rigidity, and is

20 light as well as comparatively inexpensive. Naturally, the method may also be used for producing articles, e.g. table legs and like articles, with considerably smaller surfaces than a door, but this has not been done, mainly because the expenditure of work has not been compensated for by

25 the relatively small saving in material.

The object of the present invention is to make it possible to use this method also for manufacturing, at a lower cost, certain articles, such as table legs, having a comparatively small surface. This object is achieved in

30 that the blank is sawn across the laths, such that a number of elongated pieces with rectangular cross-section are obtained, that said pieces are rotated through 90° about their longitudinal axis and positioned parallel to each other on a third glue-coated panel and covered with a

35 fourth glue-coated panel, whereupon the last-mentioned panels are subjected to pressure and glued together, and that the unit thus produced is sawn along and between the elongated pieces which are then reworked.

The invention will be described in detail below, reference being had to the accompanying drawings illust¬ rating an embodiment. Figs 1 and 2 are a side view and a top plan view, re spectively, illustrating how a blank for manufacturing articles according to. the invention is produced.

Figs 3 and 4 are a top plan view and an end view, respectively, illustrating how the blank in Figs 1 and 2 is worked for producing the article according to the invention, and

Figs 5a, 5b and 5c are sectional views showing possible embodiments of the article according to the invention. Figs 1 and 2 show a blank 10 comprising two fibre- boards 11, 12, three parallel laths 13, 14, 15, and honeycombs 16 of cardboard. Thus, the blank 10 has a construction common in the manufacture of doors, apart from the fact that a door has laths along all sides. Such a blank is manufactured by providing one flat side of a first panel 11 with a glue coating, whereupon the laths 13, 14 and 15 are positioned parallel to each other along the opposing sides of the panel and in an intermediate position. The spaces defined by the laths 13, 14 and 15 are filled with honeycombs 16 of the same height as the laths and serving as spacing means. A second panel 12, which also has a glue coating on one flat side, is positioned on the laths 13, 14 and 15 and the honeycombs 16, the glue-coated side facing the honeycombs, whereupon the unit is subjected to pressure and glued together. The glued construction has high torsional and compressive strength, as has a door manufactured in this manner.

Then, elongated pieces, for example suitable as tabl legs, are manufactured from the construction 11-15, and for this purpose, the blank 10 is sawn across the laths 13, as illustrated by the saw cuts 17 in Fig 2, to form the pieces which are generally designated 20 and have, a each end, a block 13' and 15' formed of the laths 13 and 15, as well as an intermediate block 14', and between these there are honeycombs strips 16'. To complete the construction, the pieces 20 are rotated through 90° about their longitudinal axis and positioned parallel to each other on a third glue-coated fibreboard 18, as shown in Fig 3, and a fourth glue-coated fibreboard 19 is posi¬ tioned on top of the laid-out pieces 20. As indicated at 21, said pieces 20 are not placed closely together but with a predetermined interspace. Thereafter, the panels

18, 19 are subjected to pressure in the same manner as the panels 11, 12 and glued together. The resulting construc¬ tion is then sawn along the pieces 20 and in the middle of the space 21 maintained therebetween, such that one ob- tains elongated pieces according to Fig 4, the spaces 21 providing a polishing allowance on opposite sides.

After polishing and finishing, the produced elongated pieces are ready to be used, for example as table legs. As such, they function extremely well, thus evidencing their excellent strength properties.

Many different types of materials can be used in the application of the above-mentioned method. Apart from fibreboard, the panels 11, 12, 18 and 19 may consist of MDF panels, laminate, particle board, veneer, plywood, cardboard, plastic, metal etc, and the parts 13, 14 and 15 called "laths" may consist of solid wood, particle board or any other suitable material to which fittings or holders may be attached. Preferably, a honeycomb of card¬ board is used as spacing element because of the low price and excellent properties of cardboard, but the honeycomb structures may also be made of e.g. plastic. In lieu of honeycombs, a suitable foam plastic material, e.g. poly- urethane, may be disposed in the space between the laths. The drawings illustrate the manufacture of table legs in which the laths 13, 14 and 15 form an upper block 13', a mid block 14' and a lower block 15' in the table leg. For shorter table legs, only two blocks may be needed, while longer legs may require more than three blocks. The panels 11, 12, 18 and 19 do not necessarily have to be made of the same material. If the article is not to be used as a table leg, but as, for example, a table frame, in which case one edge is applied against a surface as shown in Fig 5a, the panel forming this edge may consist of a comparatively inexpensive material, such as card¬ board. It is also possible to split the elongated pieces, for instance along the diagonal, in order to obtain e.g. triangular legs, as shown in Fig 5b, in which case the side resulting from the split is covered with a strip of the same material as the two other sides. The sides of the elongated pieces may also be provided with recesses for accommodating a panel or the like, as indicated in Fi 5c. The panels should then be made slightly thicker.

The invention makes it possible to manufacture, at a lower cost, a great number of different structural ele¬ ments and furniture components with, excellent strength.
