Definitions

  • the present invention is generally concerned with fArrniture and more specifically it is concerned with applying a webbing such as a seat portion, a backrest, etc. to the furniture frame.
  • a webbing such as a seat portion, a backrest, etc.
  • the term "furniture” denotes any type of furniture used for seating such as, for example, chairs, armchairs, rocking chairs, stools, seats, sofas, garden furniture, etc.
  • the term “webbing” as used herein in the specification and claims denotes a flexible surface of the furniture suitable for supporting a person using the furniture, e.g. a seat, a backrest, a leg rest, etc.
  • Such webbing may be typically made of a uniform material or made of flaps, typically transversing one another.
  • a furniture item comprising at least one support portion, said at least one support portion comprising a receiving frame and a support member comprising a webbing made of flexible material fitted at its edges with frame engaging profiles formed with first engaging members for secure engagement with corresponding second engaging members of the receiving frame; the invention characterized in that said frame engaging profiles are integrally molded with said webbing.
  • the webbing may be a sheet of material or a mesh or a plurality of straps, typically transversely extending.
  • the webbing is made of or coated with a thermoplastic material.
  • the webbing is a mesh of fabric woven of polymeric yarns coated with thermoplastic material and the frame-engaging profiles are made of material having a substantially low coefficient of thermal expansion (CTE).
  • the frame-engaging profiles are made of a thermoplastic material which is injection moldable and heat weldable with the coating of the webbing.
  • the frame-engaging profiles are made of non- thermoplastic material though moldable, e.g. metal, composite materials, etc.
  • the frame-engaging profiles form a closed frame structure corresponding with the shape of the receiving frame.
  • the frame-engaging profiles are non uniform and are attachable one by one to the receiving frame.
  • the webbing has a roughened texture at least at zones attached to the frame-engaging profiles. Alternatively, or in addition, this may be obtained by forming said zones with pores, whereby material of the frame-engaging profiles penetrates through the webbing to thereby increase mechanical engagement therebetween. Furthermore, the frame-engaging profile may sandwich edges of the webbing whereby such sandwiching may be obtained by penetration through the webbing.
  • the frame-engaging profiles are detachable from the receiving frame whereby the support member may be removed, e.g. for cleaning and maintenance or replaced. Such removable connection may be, for example, a snap-type engagement.
  • the invention is further concerned with a method for manufacturing a support portion for a furniture item, said support portion comprising a receiving frame and a support member comprising a webbing made of flexible material fitted at its edges with frame engaging profiles formed with first engaging members for secure engagement with corresponding second engaging members of the receiving frame; the method includes integrally molding of the said frame engaging profiles with the webbing.
  • the webbing is made of a mesh fabric woven of polymeric yarns coated with a thermoplastic material whereby the frame-engaging profiles are made of a material having a substantially low coefficient of thermal expansion (CTE) and wherein during molding the frame- engaging profiles are heat welded to respective portions of the webbing.
  • CTE coefficient of thermal expansion
  • Fig. 1 is an isometric view of a furniture, a garden chair in the present example, in accordance with the present invention
  • Fig. 2A is an isometric top view of a receiving frame removed from the chair of Fig. 1
  • Fig. 2B is a top view of the receiving frame seen in Fig. 2 A
  • Fig. 3A is a top isometric view of the support member removed from the chair, in a position as removed from the mold
  • Fig. 1 is an isometric view of a furniture, a garden chair in the present example, in accordance with the present invention
  • Fig. 2A is an isometric top view of a receiving frame removed from the chair of Fig. 1
  • Fig. 2B is a top view of the receiving frame seen in Fig. 2 A
  • Fig. 3A is a top isometric view of the support member removed from the chair, in a position as removed from the mold
  • Fig. 1 is an isometric view of a furniture, a garden chair in
  • FIG. 3B is a bottom isometric view, illustrating the support member of Fig. 3 A in a position prior to engaging with the receiving frame of Figs. 3 A and 3B;
  • Fig. 4A is an enlargement of the portion marked III in Fig. 3 A;
  • Fig. 4B is an enlargement of the portion marked III in Fig. 3 A as seen from below;
  • Fig. 5 is a local section along lines V-V in Fig. 1, illustrating how the support portion is engaged with the furniture item.
  • Fig. 1 illustrates an armchair generally designated 10 of the type commonly used as garden furniture, and which comprises several frame components namely legs 12, armrests 14, a seat 16, and a backrest 18, which in the present example is inclinable between several respective positions.
  • the frame components are made of molded plastic material though this is not necessarily the case and the frame components may be made, for example, of wood, metal, etc., or of a combination of several such materials.
  • the chair may be collapsible and/or stackable, as known with such plastic chairs which are often referred to also as “garden furniture " and “garden chairs”, respectively.
  • garden furniture and “garden chairs”
  • the seat 16 and the backrest 18 comprise a support portion 24 and 26, respectively, which as will be explained hereinafter in more detail are made of flexible webbing attached to the respective frame.
  • a support portion 24 and 26, respectively which as will be explained hereinafter in more detail are made of flexible webbing attached to the respective frame.
  • the seat 16 Embedded within the seat frame 16 there is a receiving frame 30 (independently shown in Figs. 2A and 2B) which in the present embodiment is a rectangle though other shapes are possible just as well.
  • Receiving frame 30 may be integrally formed with the respective frame member (seat 16 or backrest 18) e.g. in an injection molding process, or else it may be fixedly attached thereto.
  • the receiving frame 30 comprises a peripheral recess 32 substantially vertically extending from a top edge 34 towards a bottom edge 36 (Fig. 2A) with a plurality of openings 40 formed at a bottom surface of the recess 32.
  • the receiving frame 30 is made of a rigid material and has a webbing support surface 42 and a gradually inclined or curved surface 44 to allow some deformation of a webbing under load, i.e. weight of a person seated on the chair. Further attention is now directed to Figs.
  • the webbing 54 is made of mesh fabric woven of polymeric yarns coated with a thermoplastic material, e.g. PVC. Such mesh is often referred to as Textilene® and is available in different colors and density.
  • the webbing 54 has a roughened surface at least at its peripheral zones (59 in Fig. 4A) where the frame- engaging profiles 56 extend.
  • said peripheral zone 59 may comprise pores to further increase mechanical attachment with the frame- engaging profiles, as will be explained hereinafter.
  • the frame-engaging profiles 56 extend along edges of the webbing 54.
  • the profiles 56 are individual profiles though in accordance with other embodiments (not shown) the profiles may be formed into a rigid frame consisting of two or more such frame-engaging profiles or, each edge of the webbing may comprise several frame-engaging profiles rather than a continuous profile as illustrated in the annexed figures.
  • the frame-engaging profiles 56 comprise a ruler portion 62 corresponding in shape with the recess 32 of the receiving frame 30 such that at the assembled position (Fig. 5) the ruler conceals the recess 32.
  • Each of the profiles 56 comprises a plurality if first engaging members 66 fitted at their free end with a lug 68 for snap engaging within recesses 40 of the receiving frame 30, as seen in Fig. 5.
  • the support member 50 is manufactured in an injection molding process where a sheet of webbing material 54 is applied into the mold (not shown) where injection moldable, thermoplastic material (e.g. ABS) is injected into the mold and whereby molten material flows through the pores of the webbing 54 allowed to expand into preformed support ribs 70 which may also be in the form of support surfaces (not shown).
  • injection moldable, thermoplastic material e.g. ABS
  • the frame-engaging profiles 56 are molded and integrated with the webbing 54 such that attachment of the profiles 56 to the webbing 54 is obtained by both heat welding of the thermoplastic material of the welded profiles which heat welds to the thermoplastic coating of the webbing and further by mechanical attaching, i.e. penetration of the molded material through the pores of the webbing and further by the sandwiching of the ribs 70. It is appreciated that rather than ribs 70 the edges of webbing 54 may be entirely sandwiched by corresponding portions of the frame-engaging profiles (not shown).
  • the frame-engaging profiles 54 are made of a material having a substantially low coefficient of thermal expansion (CTE) whereby after withdrawal of the integral support member 50 from the mold, the frame-engaging profiles substantially do not deform, retaining the webbing 54 in an essentially flat position.
  • Fig. 3A illustrates the position of the support member 50 as it is withdrawn from the mold.
  • Engaging the support member 50 to the receiving member 30 is carried out by introducing the first engaging members 56 into the corresponding recesses 32 to thereby facilitate snap engagement of lugs 68 within recesses 40.
  • the snap engagement may be disengaged, e.g. by the aid of a tool such as a screwdriver. It is further appreciated that other forms of engagement may be utilized, e.g.
