Brief Patent Description - Full Patent Description - Patent Application Claims
FIELD OF THE INVENTION [0001] The present invention is generally concerned with furniture and more specifically it is concerned with applying a webbing such as a seat portion, a backrest, etc. to the furniture frame. [0002] Hereinafter in the specification 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. [0003] 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. BACKGROUND OF THE INVENTION [0004] A variety of methods exist for attaching webbing to a furniture's frame, to thereby provide a comfortable and pleasant support surface serving, e.g. as a seat portion or a backrest. [0005] Examples of disclosures of such methods are, for example, U.S. Pat. Nos. 3,512,834, 5,015,034, 5,338,091 and 5,662,383. [0006] It is a primary object of the present invention to provide a furniture wherein the webbing material is attached to the frame of the furniture in a fast, easy and cost effective fashion. This is achieved by integrally molding of the webbing with profiles which are in turn easily engageable with a receptacle of the furniture's frame. SUMMARY OF THE INVENTION [0007] According to the present invention there is provided 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. [0008] The webbing may be a sheet of material or a mesh or a plurality of straps, typically transversely extending. [0009] The webbing is made of or coated with a thermoplastic material. In accordance with one of its embodiments, 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. However, according to other embodiments, the frame-engaging profiles are made of non-thermoplastic material though moldable, e.g. metal, composite materials, etc. [0010] In accordance with one particular embodiment the frame-engaging profiles form a closed frame structure corresponding with the shape of the receiving frame. However, in accordance with another embodiment, the frame-engaging profiles are non uniform and are attachable one by one to the receiving frame. [0011] In order to increase attachment of the frame-engaging profiles to the webbing material, it is advantageous that 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. [0012] In accordance with one particular embodiment 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. [0013] 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. [0014] In accordance with the method of the invention, 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. [0015] In accordance with a particular embodiment, during the molding process, the material of the frame-engaging profiles penetrates through the webbing to thereby increase mechanical engagement therebetween. BRIEF DESCRIPTION OF THE DRAWINGS [0016] In order to understand the invention and to see how it may be carried out in practice, an embodiment will now be described, by way of a non-limiting example only, with reference to the accompanying drawings, in which: [0017] FIG. 1 is an isometric view of a furniture, a garden chair in the present example, in accordance with the present invention; [0018] FIG. 2A is an isometric top view of a receiving frame removed from the chair of FIG. 1; [0019] FIG. 2B is a top view of the receiving frame seen in FIG. 2A; [0020] FIG. 3A is a top isometric view of the support member removed from the hair, in a position as removed from the mold; Continue reading about Furniture item and a method for attaching webbing thereto...
