Abstract
Abstract A support for furniture, such as outdoor furniture, has a support frame and stretched thereon is a net or lattice-like arrangement of flat web strips of plastics material; where they cross one another the strips are bonded together by means of thin planar enveloping members. The webs extend between and are secured to opposite sides of the frame, and to each end of each web a securing member is attached; each web is secured to an associated side of the frame by looping its end around the side and fastening the end by means of slipping the securing member onto the strip itself in the vicinity of the frame. Several forms of securing member are disclosed, and in each case the member is slotted or U-shaped enabling the member to be slipped transversely onto the strip. Each member has means to prevent the securing member inadvertently slipping transversely off the strip.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
171 words
A filament strip support for furniture intended to be sat, lain or reclined on, comprising an array of filaments which extends in one longitudinal direction, thereby to form a filament strip support construction, attachment means for securing said filaments at their free ends to a frame of a piece of furniture, each of said filaments being in the form of a flat strip, and each of said filaments being connectable to a part of said frame by passing an end of said strip around said frame part to form a frame encircling loop, and securing said end to the strip itself by means of a securing member adapted to grasp said strip and constituting one of said attachment means, said securing member is in the form of a clasp to be placed astride the said strip, said attachment means further includes a separate transverse locking member, said clasp having a pair of arms for holding the ends of said locking member, the latter being secured to the end of said strip.
Claim 2
Dependent Claim
171 words
A filament strip support for furniture intended to be sat, lain or reclined on, comprising an array of filaments which extends in one longitudinal direction, thereby to form a filament strip support construction, attachment means for securing said filaments at their free ends to a frame of a piece of furniture, each of said filaments being in the form of a flat strip, and each of said filaments being connectable to a part of said frame by passing an end of said strip around said frame part to form a frame encircling loop, and securing said end to the strip itself by means of a securing member adapted to grasp said strip and constituting one of said attachment means, said securing member is in the form of a clasp to be placed astride the said strip, said attachment means further includes a separate transverse locking member, said clasp having a pair of arms for holding the ends of said locking member, the latter being secured to the end of said strip.
Claim 3
Dependent Claim
29 words
A support as claimed in claim 1, wherein said arms of the clasp have opposed, aligned receiving pockets adapted to receive therein the ends of said transverse locking member.
Claim 4
Dependent Claim
45 words
A support as claimed in claim 2, wherein each of the receiving pockets has an introductory slot for the ends of the locking member, the slots extending away from the end of said strip when the latter is in its secured position on said frame.
Claim 5
Dependent Claim
34 words
A support as claimed in claim 3, wherein there is means to prevent an outward displacing movement of an inserted end of the transverse locking member from said pockets provided in each introductory slot.
Claim 6
Dependent Claim
35 words
A support as claimed in claim 3, wherein each introductory slot has a funnel-shaped entry portion remote from the associated pocket to facilitate insertion of the ends of the transverse locking member into said slots.
Claim 7
Dependent Claim
36 words
A support as claimed in claim 3, wherein said displacement-preventing means is formed by constrictions in said introductory slots, said constrictions having widths less than the corresponding widths of the ends of said transverse locking member.
Claim 8
Dependent Claim
33 words
A support as claimed in claim 1, wherein said receiving pockets and said introductory slots are in the form of recesses in the confronting inside surfaces of the said arms of the clasp.
Claim 9
Dependent Claim
43 words
A support as claimed in claim 1, wherein said clasp is U-shaped, the arms forming the libs of the U, and the base of the U has a strip-confronting surface which in a cross-sectional outline projects at an obtuse angle towards the strip.
Claim 10
Dependent Claim
40 words
A support as claimed in claim 1, wherein said clasp is U-shaped, the arms forming the limbs of the U, and the base of the U having a strip-confronting surface which comprises at least two surfaces angled towards the strip.
Claim 11
Dependent Claim
26 words
A support as claimed in claim 1, wherein the said two surfaces are furnished with projections to prevent relative slipping between said strip and said clasp.
Claim 12
Dependent Claim
45 words
A support as claimed in claim 10, wherein said projections are inwardly projecting ribs aligned transversely to the longitudinal direction of the strip and which are substantially triangular in cross-section, said ribs extending over at least a portion of the region of the strip width.
Claim 13
Dependent Claim
28 words
A support as claimed in claim 1, wherein said arms have edges adapted to the external contour of said frame to permit said arms to bear snugly thereagainst.
Claim 14
Dependent Claim
25 words
A support as claimed in claim 1, wherein the transverse locking member is received in a folded-over holding loop at the end of said strip.
Claim 15
Dependent Claim
24 words
A support as claimed in claim 1, wherein the transverse locking member is embedded in a thickened portion of the end of the strip.
Claim 16
Dependent Claim
15 words
A support as claimed in claim 1, wherein said clasp is an injection-moulded plastics member.
Claim 17
Dependent Claim
19 words
A support according to claim 1, wherein the filaments of each array thereof are disposed parallel to one another.
