Abstract
Abstract A furniture frame is disclosed in which the ends of furniture springs are coupled to two spaced opposing metal frame members by plastic clips which have been secured in a friction-fit-manner to flanges formed in each frame member. The flange of each frame member extending in a direction away from the opposing frame member to an open end. Each clip having a generally S-shaped profile and including a frame engaging hook portion which is separated from a spring engaging hook portion by a central portion of the clip. The frame engaging hook portion and central portion defining a slot opening in a first direction, and which is sized to receive therein in a friction-fit the open end of a flange. The spring retaining hook portion and central portion defining a second slot opening in a direction opposite to the first direction, and which is sized to receive and retain therein one end of the spring.

Claim 1
Independent Claim
326 words
In combination a furniture frame with spaced first and second frame members, elongate spring means having a first end and a second end and catch means at said first end, anchor means for securing the first end of the spring means to the first frame member, the spring means spanning between the frame members with the first end connected via the anchor means to the first frame member and the second end connected to the second frame member, the first frame member including a thin flange member having generally planar surfaces extending from the first frame member to a distal end of the flange member in a direction away from the second frame member, the anchor means comprising a generally S-shaped clip member including a spring retaining hook portion, a frame engaging hook portion, and a central portion between the spring retaining hook portion and the frame engaging hook portion, the central portion having a forward end and a rearward end, the spring retaining hook portion extending from the central portion towards the rearward end and away from the second frame member so as to define a first slot between the central portion and the spring retaining hook portion open towards the rearward end, the first slot receiving and retaining therein the spring catch means, the frame engaging hook portion extending from the central portion towards the forward end and towards the second frame member so as to define a second slot between the central portion and the frame engaging hook portion open towards the forward end, the second slot receiving therein in a friction-fit-manner the open distal end of the flange member, the first end of the spring means secured to the first frame member with the spring catch means received in the first slot and the distal end of the flange member received in the second slot, wherein the spring means forwardly urges the second slot onto the open distal end of the flange.

Dependent Claim
326 words
In combination a furniture frame with spaced first and second frame members, elongate spring means having a first end and a second end and catch means at said first end, anchor means for securing the first end of the spring means to the first frame member, the spring means spanning between the frame members with the first end connected via the anchor means to the first frame member and the second end connected to the second frame member, the first frame member including a thin flange member having generally planar surfaces extending from the first frame member to a distal end of the flange member in a direction away from the second frame member, the anchor means comprising a generally S-shaped clip member including a spring retaining hook portion, a frame engaging hook portion, and a central portion between the spring retaining hook portion and the frame engaging hook portion, the central portion having a forward end and a rearward end, the spring retaining hook portion extending from the central portion towards the rearward end and away from the second frame member so as to define a first slot between the central portion and the spring retaining hook portion open towards the rearward end, the first slot receiving and retaining therein the spring catch means, the frame engaging hook portion extending from the central portion towards the forward end and towards the second frame member so as to define a second slot between the central portion and the frame engaging hook portion open towards the forward end, the second slot receiving therein in a friction-fit-manner the open distal end of the flange member, the first end of the spring means secured to the first frame member with the spring catch means received in the first slot and the distal end of the flange member received in the second slot, wherein the spring means forwardly urges the second slot onto the open distal end of the flange.
Claim 3
Dependent Claim
57 words
The combination as claimed in claim 1 wherein the central portion of the clip member has a flat surface opposed to the frame engaging hook portion such that with the distal end of the flange member received in the second slot, the flat surface abuts in coplanar relation one of the planar surfaces of the flange member.
Claim 4
Dependent Claim
61 words
The combination as claimed in claim 2 wherein said flange member is provided in a generally horizontal orientation and said planar surfaces are upper and lower flange surfaces, the distal end of the flange member is received in the second slot with the flat surface abutting the upper flange surface and the frame engaging hook portion engaging the lower flange surface.
Claim 5
Dependent Claim
39 words
The combination as claimed in claim 3 wherein the frame engaging hook portion includes a rib member extending into the second slot to engage said lower flange surface to restrict removal of the distal end from the second slot.
Claim 6
Dependent Claim
23 words
The combination as claimed in claim 1 wherein the frame engaging hook portion extends substantially to the forward end of the central portion.
Claim 7
Dependent Claim
77 words
The combination as claimed in claim 1 wherein the frame engaging hook portion is resiliently deformable away from the central portion from an unbiased position, wherein the frame engaging hook portion angles towards the forward end of the central portion, to a biased position away from the central portion, the flange member having a thickness to urge the frame engaging hook portion away from the unbiased position when the distal end is inserted into the second slot.
Claim 8
Dependent Claim
60 words
The combination as claimed in claim 6 wherein a forwardmost end of the frame engaging hook portion includes a camming surface extending rearwardly and towards the central portion to engage the distal end of the flange member on insertion of the distal end into the second slot and assist movement of the hook engaging portion away from the unbiased position.
