Definitions

  • the invention relates to a plate to be fitted on strawbottomed chairs which can be made automatically thus doing away with the usual long manual work required for the covering or the re-covering with straw.
  • prior straw plates are covered with an interlacing of plant fibres joined in a continuous way.
  • the chair plate has the appearance of a frame the center part of which is empty; the appearance of the outer side is obtained, at the same time the central part of the frame is filled-up, by this interlacing of fibre which takes a long time to make.
  • FIG. 1 shows a chair plate made according to the usual hand process.
  • Fibres A interlace with other fibres B, the latter being arranged on a plane at a right angle towards the others; the interlacing forms two diagonals C and D which give to the seat its concave shape.
  • the interlacing of fibres according to the drawing shown on FIG. 1 is the most usual, but different other geometric designs can be obtained depending on the shaping used.
  • the object of the invention is to overcome the inconveniences arising from this handicraft work and relates, to this end, to a straw plate for a piece of furniture, such as a chair, in which said plate is made of several units covered separately in such way that, when grouped together, said units reproduce the final aspect of the plate desired.
  • Each unit includes fastening parts which work with fastening parts rigidly locked with contiguous units.
  • a chair straw plate, according to the invention, is shown as a nonrestricted example, on the attached drawings in which:
  • FIG. 2 shows a top view of the seat plate made from various units according to the invention, said units being not yet covered with straw.
  • FIG. 3 shows a cross-section view along the line J-J in FIG. 2 of a unit fitted with struts, according to the invention.
  • FIG. 4 shows a view along the line GG in FIG. 2, front units being removed.
  • FIG. 5 shows a view in perspective of the detail of an assembly of corners of two solid units.
  • FIG. 6 shows the various units partly completed which form the plate of a seat, according to another making process.
  • FIG. 7 shows another making process for the manufacture of the plate units in a single mechanic operation.
  • FIG. 8 shows another process for the covering of the plate units, according to the drawing of FIG. 7.
  • a straw plate of a seat is composed of an assembly of four separate units 1, 2, 3, 4 not covered with straw.
  • These separate units 1, 2, 3, 4 which have a triangular shape, approximately, are composed of an external frame, the hollow central part of which is so designed that units 1, 3 and 4, or the central part fitted with struts 2a, 3a at right angles, will form a square which stiffens the rigidity of this unit.
  • the triangular frame of units 1, 2, 3, 4 includes a rim 2c, as this is shown for unit 2, which is approximately at a right angle with the surface of the unit and has the shape of the cog serrated edge of the unit.
  • This rim increases the rigidity of the assembly. It includes swells intended for the housing of fastening parts 3e, such as screws, pegs or similar pieces, working with tightening parts such as nuts or similar pieces held by corresponding swells of the contiguous edges of the abuttin-g units.
  • the corner assembly is made by interlocking two male and female moulded parts 10 and 11.
  • Male part 10 is, for instance, set at the various corresponding corners of units 1, 2, 3, 4, while the female part 11 is rigidly locked with the other corners of the base of the triangular units 1, '2, 3, 4, in such way that alternately, male unit 10 of a unit interlocks with female unit 11 of the adjacent corner of the abutting unit.
  • male parts 10 are rigidly fastened with the corners of straw units 2 and 4, while female units 11 are rigidly fastened with the corners of straw units 1 and 3.
  • This assembly by interlocking of two units 10 and 11, in shape of a case, imitates the wood corners of the straw plates of chairs made according to handicraft processes.
  • Such assemblies made with cases, allow the maker to reduce considerably the quantity of material used by comparison with a solid parts assembly 12, 13 as shown on FIG. 4, while they give an impression of a certain volume.
  • interjacent fastening units 1d, 22, 2d, 1e can be left out and replaced by a single central assembly 9 made, for instance, by the using of a groove 9a into which is set a split ring 9!).
  • central assembly 9 may be as well composed of an assembly including screws, hooks, or any other means of assembly, fastening for instance the corners of the units to a central small plate.
  • the assembly obtained by using fastening parts 1d, 112, 2d, 2e, etc. between the adjacent sides of the various units increases the stiffness of such a seat plate and, consequently, makes it less comfortable.
  • the thickness of walls 20 can be reduced, so as to increase flexibility, and the latter method allows the maker to bring down the weight of the material used and, as a consequence, the cost price of the plate.
  • units 1, 2 and 4 shown on FIG. 2 are composed of a frame having a shape approximately triangular and are not fitted with struts 2a and 3a as unit 2 is.
  • FIG. 4 shows in detail the various types of assembly between the two adjacent units 1 and 4, by means of male and female cases and 11, and of a central assembling part 9 made of a groove 9a and a ring 9b.
  • units 1 and 4 of FIG. 4 do not include cog or serrated edges allowing the holding of the fibres in the right position.
  • units 1 and 4 include three strands of fibres 12 which allow the maker to see their marks in the part close to the center, as well as their fastening in the notches made in the edges of the respective units.
  • the central strand which is made of straw fibres, is replaced by a central strand prefabricated or moulded, made of wood, plastics, foam or any conglomerate.
  • the scheme which appears on FIG. 2 is not restricted and the visible plate may be cut out (when coated with fibre) according to the geometric pattern desired.
  • Each triangle, required for the making-up of a visible plate, is then covered separately with straw fibres (or with a synthetic thread), in such way that, when completed, each triangle appears like those shown under marks 21 and 24; triangle shown under mark 23 is re-covered with a flexible synthetic material 25, which there again gives the right softness to the seat plate.
  • This flexible material 25 may be glued, stapled, or merely laid on the plate, the re-covering with straw fibres, made afterwards, securing it once for ever.
  • the triangle 22 is partially covered with straw fibre.
  • the inclined sides of each triangle are cut away at 26 in order to secure the covering of plant fibres.
  • fibres must be glued together, of course, as well as the surfaces and the sides of the two units.
  • a straw plate construction for a furniture seat comprising a plurality of approximately triangular separate plate units disposed in narrowly-spaced adjoining relationship defining a quadrilateral structure having base edges and base corners facing outward and apex edges and apex corners facing inward toward one another,
  • each unit including an approximately triangular body with a cover of cord-like material disposed thereon in courses arranged in side-by-side abutting engagement with one another,
  • each body includes an open-centered frame with said cover extending thereacross.
  • a straw plate construction according to claim 1, wherein said apex edges have cutaway portions extending therealong and wherein said courses of said cord-like material are disposed in said cutaway portions.
  • a straw plate construction according to claim 1, wherein said base edges have serrations forming notches therein and wherein said courses of said cord-like material are disposed in said notches.
