SPRING` l SEAT CONSTRUCTION Filed Oct. 24
Patented Aug. 18, 1942 UNITED PATENT josFiFgI "SPRING SEAT CONSTRUCTION A Charles S. Viall, ",Srg, `andr Stanley :Overbyplig'lewoud, -Calif.;s"ad Viall assigner to saidverby' Application -oew'ber '24, 193s, serial No. zsl'is 33 Clai'ms.
Our invention relates to spring seat construction, and more particularly to spring seat construction for upholstered furniture.
f An important object of the invention is to provide spring seat construction that will give greater comfort and ease, together with simplicity, durability, reliability, inexpensiveness in construction, and general efficiency.
Another object is to provide means that will eliminate the use of coil springs, eliminate the necessity of manualor'mechanical tying of such springs, and eliminatewebbing for such springs, all now in use in spring construction for upholstered furniture.
The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description. However, the drawing merely shows and the following description merely describes an embodiment of the present invention, which is given by way of illustration or example only.
In the drawing, like reference characters designate similar parts in the several views.
Figure 1 is a plan View of an embodiment of the present invention.
Figure 2 is a cross section of same, taken on the line 2-2 of Figure 1.
Figure 3 is an enlarged, sectional view looking in the` direction of the arrows 3--3 of Figure 2.
Figure 4 is a reduced modified construction for a seat element. f
Figure 5 is an edge View of the modification shown in Figure 4.
Figure 6 is an enlarged view of a detail shown in Figure 3.
Referring more in detail to the drawing, the reference numerals 6 designate brace members of the frame of a chair, which brace front and rear legs 'I and 8.
A platform 9 is mounted in the framework of the chair. The platform shown in Figures 1 to 3 comprises a resilient steel frame I0 of the shape shown in Figure 1. Fabric I2 is stretched upon the frame and is hemmed around the frame members, as suggested at I3. The hem is stitched in position, as shown at 31.
The platform is supported on springs I4, I5, I6 and I'I. Each of the springs comprises horizontal members I8 and I9 that are respectively` fastened on the frame by means of screws 2U and in sleeves 2 I, 29 and 30 fastened on the platform.
Diverging arms 22 and 23, adjacent the end members, connect With parallel members 24,
which in turn connect with an open -spring loop 25.
Allof the springs have substantially this same sha-pe. The springs oneach `side face in -oppof site directions, so as to resist sway `of the Vplatform sideways, forward and backward,
At the corners of theplatform -and'frame, the open-portions of thespringloops are arranged to face in directions'substantially at right angles `to each other. Y
Another featurelof the `spring members is that the diverging Aarms `22 `and V2-3are angula-rly arranged when viewed in plan, as shown in Figure l. These laterally bent diverging arms 22 and 23 are found on all springs except the rear springs Il. These rear springs have their lower end portions 26 aligned with the loop member 21, which'loop member conforms in shape to the loop 25 in Figure 3. The opposite end of each rear spring angles, as shown at 28, and the right angular bent ends 28 are fastened in the rear sleeves 30.
At the front of the chair the horizontal por-A tions I9 of the front springs I4 are fastened in the sleeves 2I, whereas the horizontal portions I9 of the side springs I5 are fastened in the sleeves 29 on the sides of the platform.
In the modification shown in Figures 4 and 5,. a frame 3| describes the contour of the modified platform, which is substantially the same shape as the platform in Figures 1 to 3. How-- ever, the bracing means in Figure 4 comprises a series of braces in substantially rectangular form, as shown at 32. Fabric 33 is stretched over the frame and may be hemmed around thev periphery in order to hold the fabric in place.
The braces used in the form shown in Figures: 1 to 3 comprise cross members 34 and 35 disposed substantially at right angles to each other. These cross members 34 and 35 are bowed down-- wardly, as shown in Figure 2.
While we have illustrated and described whatwe now regard as the preferred embodiment of our invention, the construction is, of course, subject to modifications without departing from the spirit and scope of our invention. We, therefore, do not wish to restrict ourselves to the particular form of construction illustrated and described, but desire to avail ourselves of all modifications which may fall within the scope of the appended claims.
Having thus described our invention, what we claim and desire to secure by Letters Patent is:
1. In a spring seat `construction having a frame and a seat support spaced vertically above I1 is bent substantially at right said frame, spring means in the space between the frame and seat support for resiliently supporting the latter, consisting of unitary springs arranged at substantially the corners of a rectangular area in said space beneath the seat support, each of said springs including a pair of vertically disposed, open spring loops projecting substantially at right angles to each other and substantially, partially along the sides of said rectangular area, and each spring also including upper and lower members between, and connecting, the upper and lower portions of the said spring loops, the said members being respectively upwardly and downwardly offset relative to the loops and being connected respectively to the seat support and frame.
2. In a spring seat construction having a frame and a seat support spaced vertically above said frame, spring means in the space between the frame and seat support for resiliently supporting the latter, consisting of unitary springs arranged at substantially the corners of a rectangular area in said space beneath the seat support, each of said springs including a pair of vertically disposed, open spring loops projecting substantially at right angles to each other and substantially, partially along the sides of 'said rectangular area, and each spring also including upper and lower members between, and connecting, the upper and lower portions of the said spring loops, the said members being respectively upwardly and downwardly oiset relative to the loops and being connected respectively to the seat support and frame, the upwardly offset intermediate members of certain of the springs including right angular portions mating, and connected at spaced points to corner portions of the said seat support.
3. In a spring seat construction having a frame and a seat support spaced vertically above said frame, spring means in the space between the frame and seat support for resiliently supporting the latter, consisting of unitary springs arranged at substantially the corners of a rectangular area in said space beneath the seat support, each of said springs including a pair of vertically disposed, open spring loops projecting substantially at right angles to each other and substantially, partially along the sides of said rectangular area, and each spring also including upper and lower members between, and connecting, the upper and lower portions of the said spring loops, the said members being respectively upwardly and downwardly offset relative to the loops and being connected respectively to the seat support and frame, the upwardly offset intermediate members of certain of the springs including right angular portions mating corner portions of the seat support, and clips surrounding and clamping said mating portions of said springs and seat support at opposite sides of the angle thereof.
