Description
BACKGROUND OF THE INVENTION
Removable upholstery cover for furniture is shown and described in
U.S. Pat. No. 3,188,137 and U.S. Pat. No. 3,311,418, both of which
were patented by the present applicant. The constructions shown and
described therein provide advantageous arrangements for
constructing furniture units in which the coverings, typically
fabric but alternatively of other materials, have the appearance
and wearing qualities of regular upholstered fabric, but are
constructed such that the cover may be readily detached for
replacement or cleaning. In the constructions shown in these
patents, unitary but separate covers are employed for the seat and
back portions, and the side margins are thereafter concealed by
different types of arm arrangements. It may be desired for a number
of different types of constructions, however, to have a single
cover for the principal body of the furniture unit, including both
the seat and back and the visible side portions. Such a single
cover offers certain advantages over individual back and seat
covers. For example, where the back and seat are manufactured in a
unitized construction, it is desirable to use a single cover. In
addition, such a cover can have some significant cost advantages
for particular furniture styles.
SUMMARY OF THE INVENTION
The present invention is intended to obviate the problems
associated with furniture units as previously described. Furniture
units in accordance with the invention utilize a single principal
cover for the seat and back portions, as well as the side surfaces.
At a number of points on the underside of the seat portion, the
margin of the cover is secured to the underside of the frame by
sufficient elastic means to provide tightening in one direction.
Additionally, elastic means bridge the central portion of the cover
to each of the side parts which cover the sides of both seat and
back portions of the unit. The bridging elastic means may comprise
webs lying parallel to the sides of the unit, and extending along
the front, seat and both sides of the back, so as to maintain
tension in a direction orthogonal to the front to back tension. At
each end of the unit, means are provided for covering the elastic
means, such as side arm assemblies incorporating a fabric strip and
giving the appearance of a fixed structure having unitized
construction.
BRIEF DESCRIPTION OF THE DRAWINGS

accompanying drawings, in which:
FIG. 1 is a perspective view, partially exploded, of a furniture
unit in accordance with the invention;
FIG. 2 is a perspective view of the underside of the arrangement of
FIG. 1;
FIG. 3 is a cross-sectional view of the arrangement of FIG. 1;
and
FIG. 4 is a fragmentary sectional view of a portion of the
arrangement of FIG. 1, showing the manner of coupling of the arms
thereto.
DETAILED DESCRIPTION OF THE INVENTION
In a typical furniture unit in accordance with the invention,
referring now to FIGS. 1-4, a sofa 10 includes a conventional frame
and padding construction. Although a wide variety of frame
constructions may be utilized, in the unit shown a wood frame 12
incorporates a substantially rectangular base frame 14 into which
legs 15 are mounted. A flat plywood or other composition sheet 17
on the base frame 14 supports a foam or other pad 19 which is
encompassed by a muslin cover 20 fixed to the sheet 17. The muslin
cover 20 is only for purposes of retention and sealing and
therefore need not be regularly upholstered. The frame for the back
includes a pair of riser members 23 including a sheet 24 on which
the back pad 26 is supported, being retained within a muslin or
other fabric cover 28. A wide variety of other frame constructions
and paddings may be employed.
A principal cover 30 fits over this assembly, and is shown in FIGS.
1-3. The margin 33 of cover 30 is coupled to the frame 12 along the
underside periphery of the sofa 10 along both the front and back
frame members, respectively. The margin 33 may be attached to the
frame 12 in a number of ways but elastic means are provided along
at least one of the margins, front or back. In the present example,
as shown, the front and back of the cover 30 are provided with
elastic bands or loops 34 coupled to hooks 36 attached to the
underside of the frame 12 at a plurality of points. The bands 34
provide tensioning of the cover 30 from front to back. However,
alternatively, one of the margins, front or back, may be attached
to the frame by use of a Velcro tape, one part of which is seamed
to the frame and one part to the adjacent margin. The elastic bands
34 may be sewn to the cover margins or may extend through eyelets
provided along the margins (not shown). Fixed snaps may be used
along one margin, but in either event elastic tensioning of the
principal cover from front to back is provided by the elastic bands
at the opposite margin.
Two side covers 38, 39 are joined to the principal cover 30 by
elastic webs 41 only one of which is visible in FIG. 1. In the
present example, the elastic webs 41 comprise a plurality of short
elastic strips sewn at opposite ends to the side cover 38 and the
principal cover 30, respectively. The webs 41 transfer tension
between the principal cover 30 and both the side covers 38, 39
along the length of the sofa 10. The side cover margins are also
coupled to hooks 36 attached at a plurality of points along the
underside of the frame 12 by elastic bands 34. In this manner the
principal cover 30 is maintained in tension in two mutually
orthogonal directions. Alternatively, as in the case of one of the
principal cover margins, the side cover margins may be attached to
the frame by fixed snaps, Velcro tape or other equivalent means.
Each of the side covers 38, 39 includes holes 43, 44 in alignment
with channel members 48 (best seen in FIG. 4) mounted vertically in
the frame 12 adjacent the sides. The channel members are shown as
brackets attached to the seat frame and provide channels for
frictionally engaging side arm assembly posts 52, 53. However,
other alternative channel members may be used.
The webs 41 are covered by sidearm assemblies 50, one of which is
used at each end of the sofa 10. Each sidearm assembly 50 comprises
an interior frame segment (not shown in detail) from which depends
a pair of posts 52, 53 which register within the channels 48 in the
sofa 10. The sidearm assemblies 50 further comprise padding and an
exterior cover 56 having an angle configuration corresponding on
one side to the configuration of the seat and back portions of the
sofa 10. The sidearm assembly 50 therefore, when the posts 52, 53
are received within the channel members 48, fits directly over the
web portion 41, and extending flap members 58, 59 at the front and
rear portions cover the remaining portions of the web. The flap
members in the present instance include snaps 62 at their free ends
which connect with receiving buttons 64 on the sofa 10, but elastic
connectors, zippers, fasteners and a wide variety of other
detachable connecting means may be employed as desired.
As shown in FIG. 3, along the joinder line between the back and the
seat, tension on the back and seat portions of the principal cover
30 is maintained by an interior elastic coupling 60 which is
detachably coupled to an interior portion of the frame 12.
Preferably, a marginal fabric strip 63 extends from and along the
joinder line. For example, the fabric strip may be sewn along the
joinder line or seam, which strip is provided with elastic means
for detachable coupling with hooks 65 attached along the frame
member 68.
In the furniture unit thus constructed, the cover may be removed by
detaching the flaps 58, 59 of the sidearm assembly 50 and raising
the sidearm assembly 50 to remove the posts 52, 53 from the channel
members 48 in the frame 12 in which they are seated. The covers 56
on the sidearm assemblies 50 may be removed, typically being sewn
in the configuration of the sidearm assemblies 50, with a zipper
fastener 54 along one side. The elastic bands 34 on the principal
cover 30 and the fixed snaps 62 on the side covers may then be
detached from under the periphery of the sofa 10 and from over the
sides, and the single-piece cover taken off the sofa for cleaning
or replacement. The elastic webs 41 permit easier removal of the
entire cover, although zippers or Velcro strips along the corner
margins of the cover may be used for facilitating removal to a
further extent, if desired.
It will be evident to those skilled in the art that a wide variety
of frame constructions, furniture constructions and materials may
be employed in accordance with the invention. The sidearm
assemblies 50 can also be varied to a substantial extent, inasmuch
as they may be made in separate pieces, with combinations of
different materials and fastenings. Although fabric is contemplated
for the material for these in most instances, leathers and
synthetic leathers may also be utilized.
