Description
Conventional sofas, because of their large size and relatively high
backs, are difficult to move into and remove from normal living
quarters through the standard size doors, and the problem is
particularly difficult with respect to mobile homes, campers and
similar vehicles, since the doors are relatively small and the
space adjacent the doors is often restricted and precludes easy
maneuvering of the sofa through and in the area close to the door.
Further, the corridors and halls are often narrow and may prevent
movement of the fully assembled sofas therethrough. While many
sofas are constructed in such a manner that the back can be removed
and replaced, the operation is often difficult and involves a
number of pieces such as screws, bolts and fixtures. It is
therefore one of the principal objects of the present invention to
provide a sofa structure in which the back consists of a one-piece,
easily removable bolster which does not require any screws, bolts,
or fixtures to secure it firmly in place, and which can be readily
detached and replaced without the use of any tools or
equipment.
Another object of the invention is to provide a bolster type back
which, when removed, provides a low profile sofa structure that can
be moved relatively easily through doors and other restricted
areas, and which can be set in place on the sofa structure and
secured thereto by one person with very little physical effort.
Still another object of the invention is to provide a sofa with a
bolster type back which is mounted on a platform structure along
the back of the sofa and secured thereto by a Velcro type fastener,
one strip of which is secured to the lower margin of the bolster
and the other strip of which is secured to the upper margin of the
platform, thus giving easy access to the securing means of the
bolster for detaching it from and attaching it to the sofa.
A further object is to provide a sofa of the aforesaid type which
is simple in construction and easily fabricated, and which gives
firm support to the person sitting on the sofa and can be used
either with or without cushions along the back.
Another object of the invention is to provide a sofa having a
bolster type back which is normally secured firmly to the back
portion of the sofa, but which can be removed therefrom for
shipping and carrying and for moving the sofa, and which has no
protruding fixtures or other rigid parts when removed from the
sofa.
Additional objects and advantages of the present invention will
become apparent from the following description and accormpanying
drawings, wherein:
FIG. 1 is a front perspective view of a sofa embodying the present
invention, showing the sofa without the usual seat and back
cushions;
FIG. 2 is a rear perspective view of the sofa shown in FIG. 1,
showing the sofa fully assembled and the seat and back cushions in
place;
FIG. 3 is an enlarged, fragmentary, perspective view showing the
manner in which the back is secured to the principal part of the
sofa;
FIG. 4 is a perspective view similar to that shown in FIG. 1,
illustrating the manner in which the back can be removed and
replaced.
FIG. 5 is a vertical cross sectional view of the sofa, the section
being taken on line 5--5 of FIG. 1; and
FIG. 6 is an enlarged fragmentary cross sectional view
corresponding to the portion enclosed by the circle 6 in FIG.
5.
Referring more specifically to the drawings, numeral 10 indicates
generally a sofa, a number of parts of which are considered
conventional for the purpose of the present invention, the sofa
having a seat portion or deck 12, support frame 14, kick board 16,
arms 18 and 20, and back 22. Normally the sofa embodying the
present invention has seat cushions 24 resting on seat portion 12
and rear cushions 26, normally resting on the rear portion of seat
cushions 24 and leaning against back 22.
The deck includes a plurality of springs 28 supported by frame
member 30, padding 31, and cover 32 which forms the upper surface
of the deck, the padding 31 preferably consisting of polyfoam
material enclosed in fabric, plastic or other suitable material.
The cushions may be of any suitable material such as polyfoam
enclosed in a fabric or plastic sheet material. The covers for the
cushions and padding on the deck may be selected from a variety of
different materials.
The arms 18 and 20 are secured rigidly to frame 14 by bolts and may
be disassembled and removed from the sofa when the sofa is being
shipped and moved. The arms normally would have padding material in
the upper portion thereof and are normally covered with cloth or
plastic material compatible with that used on the cushions and
deck.
The back, to which the present invention is primarily directed,
consists of a bolster type structure 40, preferably constructed of
polyfoam material 42 enclosed in a fabric or plastic material 44,
identical to or compatible with the other cloth or plastic material
used in the sofa construction. The bolster is supported by a
platform 50 which consists of an upper horizontally disposed plate
52 supported by a front panel 54 and a rear panel 56, the plate 52
being joined rigidly to the upper edges of the two panels 54 and
56. The panels and plate are preferably constructed of wood, such
as hardwood. The upper edge of the platform extends above the upper
surface of deck 12, but preferably below the upper surface of seat
cushions 24. The platform is of rigid construction and is joined
rigidly to frame 14 by bolts or screws or any other suitable
securing means so that the deck, the frame, the two arms and the
platform form a rigid structure.
The bolster, which is substantially the same width and length as
platform 50, rests on the upper surface of the platform and is held
rigidly in place by fasteners or securing means 60 and 62 disposed
along the front and rear of the bolster and platform. The preferred
fastener or securing means consists of a product known in the trade
as Velcro having one strip 64 secured on the inner side of flanges
or skirts 68 and 70 attached to the lower front and rear edges of
the bolster. The flange or skirt may be of the same material as the
covering material for the bolster, such as cloth or plastic
material. The other portion 72 of the fastener strip is secured
firmly to the upper edge of the front and rear sides of the
platform and is in position to mate with the first mentioned part
of the fastener secured to the flange or skirt on the bolster. One
of the two mating strips consists of a plurality of thickly
disposed small plastic hooks and the other consists of small looped
strands of felt-like material into which the hooks seat, catch and
hold the strips together. The strips of the fastener may be
attached to the skirt by sewing or any other suitable securing
means, and may be attached to the platform by cement, staples or
any other suitable securing means.
In assembling the back on the platform, the bolster is placed on
the top of the platform in the manner illustrated in FIGS. 5 and 6,
and the two mating strips 64 of the fasteners secured to the skirt
on the bolster are pressed firmly against the respective mating
strip 72 on the platform, both on the front and rear sides thereof,
as illustrated in FIG. 6. After the fastener strips have been
pressed firmly together, the bolster back is held firmly in place
on the platform. The sofa can be used with or without cushions;
however, cushions are preferably used, such as those illustrated in
FIG. 5 wherein the back cushion is shown resting on the rear edge
of seat cushions 24 and leaning against the back for support.
One of the primary advantages of the present sofa is the ease with
which the back can be removed and assembled on the sofa to permit
the sofa to be moved through relatively small doors and along
narrow corridors and the like. In order to remove the back, the
cushions are removed, and the back is removed by separating the two
mating strips of the fastener by pulling the skirt of the bolster
outwardly and upwardly as illustrated in FIG. 3, thus disengaging
the hooks of one strip from the loops of the other strip so that
the two strips are fully disengaged. When the strips have been
separated in this manner, the bolster back can easily be lifted
from the sofa as illustrated in FIG. 4. When the sofa has been
placed in the desired location, the bolster back is reassembled on
the sofa by seating it on the top of the platform and then pressing
the strips of the skirts of the bolster firmly against the mating
strips on the upper edges of the sides of the platform.
While only one embodiment of the present sofa has been described in
detail herein, various changes and modifications may be made
without departing from the scope of the invention.
