Description
BACKGROUND OF THE INVENTION
The present invention relates generally to a piece of furniture,
and more particularly to a folding bed unit.
Folding bed units are already known in various constructions. The
invention is concerned with the type in which a bed folds into and
out of a box which is usually configurated as a piece of furniture,
that is provided with certain decorative aspects such as the use of
furniture-grade lumber or the like. In this type of unit it is
already known to provide a cabinet having upper cupboards and
relatively tall lower cupboards. Such a cabinet is located in front
of a nitch in a wall and folding beds are provided which can be
folded into the respective lower cupboards and, when folded in, are
closed off from view by suitable elements which are mounted at
their upper ends at the upper cupboards and at their lower ends by
a rail arrangement. Of course, in order to expose the opening or
openings through which the beds may be folded out it is necessary
to be able to laterally displace the concealing components, and in
order to make this possible within the cupboard arrangement the
components of the cupboard which are located laterally of the
concealing components must be capable of being shifted from their
planar-parallel position relative to the concealing components,
which is accomplished by shifting them rearwardly. Thereupon the
concealing components can be shifted sideways to expose the opening
through which the bed can be folded out.
However, this type of construction has the disadvantage that it
requires relatively much space and is therefore frequently not
suitable in small rooms, such as in rooms of apartments. In
paticular, behind the component which must be shifted rearwardly to
permit lateral displacement of the concealing component, there is
of course during the day (when the bed is normally not in use) lost
space corresponding to a volume equal to that of the component
which must be shifted rearwardly into this space to permit lateral
displacement of the concealing component. Such space is of course
entirely lost, a factor which is often found objectionable,
particularly in situations where the available space is small to
begin with.
Another construction known from the art utilizes only a box-shaped
enclosure into which the bed can be folded and out of which it can
be folded. The concealing component is located in front of the open
side of this enclosure and can be shifted laterally, being
connected with the enclosure to be retained in upright position.
However when the component is shifted laterally in order to expose
the opening through which the bed can be folded out or in, then it
is no longer properly guided unless there is always at least some
overlap between the component and the box. This, of course, results
in a reduction of the opening or cross-section, aside from the fact
that when the component is shifted laterally there is again lost
space behind it which cannot be used. Also, the movable component
cannot be self-constructed as a shelf or cupboard in order to form
a useful function, because this would make it so heavy that it
would be difficult to retain it in upright position when it is
shifted laterally to expose the opening, at least without
significant expenses.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide an
improved folding bed unit.
More particularly it is an object of the invention to provide an
improved folding bed unit which is not possessed of the
disadvantages of the prior art.
A concomitant object of the invention is to provide an improved
folding bed unit which requires a minimum of space and wherein a
minimum of available space will be lost irrespective of the
operative condition of the unit, that is regardless of whether the
folding bed is in open or closed position.
An additional object of the invention is to provide such a folding
bed unit in which it is also possible to displace the concealing
component to and from its position concealing the opening through
which the bed is folded into or out of its enclosure, without
having to fear damage to the surface on which the unit is
resting.
Still another object of the invention is to provide such a folding
bed unit which in addition will act as a piece of furniture, that
is which performs other functions than to merely mount and conceal
(in the closed position) the bed.
In pursuance of these objects, and of others which will become
apparent hereafter, one feature of the invention resides in a
folding bed unit which, briefly stated, comprises an upright box
dimensioned to receive a folding bed and having an open side and
upper and lower ends. A bed is connected with the box and is
foldable into and out of the same through the open side. At least
one piece of furniture is located laterally adjacent the open side
of the box and an additional piece of furniture is shiftable in a
plane forwardly of the box and the one piece of furniture between a
position concealing the open side and a position in which it
exposes the open side and is located in front of the one piece of
furniture. Guide means connects the additional piece of furniture
with the upper and lower ends of the box as well as with the one
piece of furniture to permit shifting of the additional piece of
furniture between the aforementioned positions thereof.
With such a construction the folding bed unit will require a
minimum of space, and the additional piece of furniture will be
properly guided and supported at all times, irrespective of its
position with reference to the box.
The novel features which are considered as characteristic for the
invention are set forth in particular in the appended claims. The
invention itself, however, both as to its construction and its
method of operation, together with additional objects and
advantages thereof, will be best understood from the following

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Discussing now the drawing in detail, and firstly the embodiment
illustrated in FIGS. 1-6, it will be seen that the bed itself is
identified with reference numeral 5, being pivotable about its
lower end (the end which is the lower end when the bed is in
upright folded-in position) into and out of a box portion 4 through
the open side thereof. Immediately adjacent the portion 4 is
provided one piece of furniture, the front edges of which are
located in a plane with the front edges of the open side of the box
4, and an additional piece of furniture (a concealing component) 3
is shiftable from the position shown in FIG. 2 in the direction of
the arrow S to the position shown in FIG. 4 in order to thereby
expose or conceal (depending upon the direction of shifting) the
open side of the box 4 and the bed folded into it.
In the illustrated embodiment the additional piece of furniture 3
is configurated in effect as a shelf unit having interalia a
writing surface so that it can be used as a desk. This means that
the piece of furniture 3 constitutes a fully utilizable piece of
furniture and does not merely serve a concealing function but does
in fact serve a decorative as well as a useful function, for
instance for writing purposes. However, the piece of furniture 3
could simply be a panel, for instance for decorative purposes of
furniture-grade lumber. When the bed 5 is to be folded out to
position of use the piece of furniture 3 is shifted towards the
right or towards the left in the direction of the arrow S so as to
be located in front of the piece of furniture 2. In the illustrated
embodiment the displacement of the piece of furniture, hereafter
identified as "the component" 3, takes place toward the right but
there is no reason why it could not take place towards the left if
the same or an additional piece of furniture 2 were located at the
left-hand side of the box 4, or why it could not be shifted to
either side if such a piece of furniture 2 were located at both
sides of the box 4.
In accordance with the present invention the component 3 is guided
on and connected with not only the box 4, but also the piece of
furniture 2. There may for instance be provided two rollers 20
which support the component 3 for movement, and the upper and lower
ends of the component 3 are provided with rollers 9 and 10 which
are engaged in guide rails 6 and 60, respectively. Guide rail 6 is
mounted at the upper wall 11 of the box 4, the rear wall of which
is identified with reference numeral 13; the rail 6 is constructed
as a profiled rail of substantially U-shaped cross-section whose
arms have free margins which are anchored towards one another
across the open side of the U. The rail also extends onto the piece
of furniture 2 in order to provide for appropriate guidance of the
component 3, and the latter is provided at its upper wall 12 with
two arms 7 and 8 the free ends of which are provided with rollers 9
which are received in the rail 6.
The lower end of the component 3 is similarly guided, for which
purpose a guide rail 60 is mounted on the bottom wall 14 or the
supporting wall 15 of the box 4, as well as at the laterally
adjacent piece of furniture 2, in such a manner as to be invisible
to a person viewing the unit from the front. A horizontally
extending supporting wall 18 is connected with the bottom wall 16
by a vertical wall 17 and mounts two brackets 19 which serve two
journal rollers 20. Arms 70 are connected with the wall 18,
oppositely to the brackets 19, and have free ends in which rollers
10 are turnably journalled which are received in the guide rail 60
which is constructed in cross-section similar to the guide rail 6.
The angled margins of the legs of the guide rail profiles are
identified with reference numeral 1, being angled towards one
another across the open side of the respective U-shaped
cross-section in order to retain the rollers 9 and 10 and prevent
their inadvertent removal from the rails.
However, in certain circumstances the provision of the rollers 20
is undesirable because they must rest either on rails provided for
them or directly on the surface on which the unit is supported.
Such rolls must of course support the weight of at least the
component 3 and tend to wear the surface on which they roll.
Particularly if the surface is for instance linoleum or the like
they will form a ground-in dirt track which is difficult to remove,
and it is even less desirable if the surface is provided with
carpeting or the like, because the nap of such carpeting is rolled
down and over a brief period of time the carpeting becomes damaged
to such an extent that it can no longer be repaired along the track
of the rollers. As a consequence this type of folding bed unit is
frequently not used by those who have carpeting in the area where
it would normally be intended to place the unit, or else it is
necessary to remove the carpeting to such an extent that it would
terminate outside the range of contact of the rollers with the
floor.
According to a further embodiment of the invention this can be
avoided by having the component 3 suspended from the additional
piece of furniture as shown in the embodiment of FIGS. 8-13.
In these FIGS. 8-13 it will be seen that like elements as in the
preceding embodiment are again identified with the same reference
numerals. As before, the piece of furniture 2 may of course either
be separate from or be of one piece or connected with the box 4, as
desired and as the case may be.
The box 4 has a base socket portion 4a and mounted on the same,
preferably extended in one piece over the entire width of the box 4
as well as of the piece of furniture 2, is an upwardly open
U-profiled guide rail 6 in which the rolls 9 are received. The arms
7, which correspond to those previously mentioned, extend out of
the plane of the rear wall 22 of the component 3 and are guided and
supported on a free leg of the upwardly open U-profiled rail 6, as
illustrated. To provide a proper guidance the rollers 9 are
provided with circumferential grooves 23 each of which embraces one
arm of the leg of the rail 6. The supporting rollers 9 are not
located beneath the component 3 in this case, but are rearwardly
offset relative thereto, so that the component 3 is completely out
of the contact with the floor beneath and is freely suspended on
the box 4 and the piece of furniture 2, being laterally movable on
the two.
Of course, being suspended in this manner, the component 3 will
have a moment of tilting in the direction of the arrow B, that is
it will attempt to tilt forwardly and downwardly, especially in
view of the fact that it is journalled at points located outside
its center of gravity. In order to counteract this tilting moment
the upper surface 11 of the box 4 and the piece of furniture 2,
rearwardly offset from the front edge thereof, is provided with the
rail 60 which is also a U-profiled rail and the margins 1 of whose
legs are inclined towards one another across the open side of the
U, to define between themselves a slit 24 through which an arm 70
extends. The slightly offset end portion of the arm 70 carries a
similarly offset pivotable bracket 25 the free ends of which are
provided with double rollers 26. The latter operate in horizontal
direction as shown in FIG. 11 and always follow precisely the
position of the rail 60, even if the material of the components 2
and 4 is of wood and should have become warped or the like or if
the rail 60 is not mounted completely straight. Brackets 25 are
pivotable about pivots 27 which are located at the end portion of
the arms 70 approximately midway thereof. Screws 28 are provided
for mounting the arms 70 to a supporting member 29 which in turn is
made fast on the surface 30 of the component 3. Two of these
supporting members 29 are provided carrying the arms 70 with the
respective brackets 25 and the associated double rollers 26, thus
providing for a proper and even guide of the component 3. This
construction of the upper guidance for the component 3 overcomes
the slight tilting moment B of the component 3 so that the lower
rail 6 supports the weight of the component 3 whereas the upper
rail 60 only has a guiding function and has to withstand the
relatively small tensile forces resulting from the tilting moment
B.
Of course, it is possible to depart from the illustrated exemplary
embodiment, for instance to have the rollers 9 roll on the
bight-wall of the U-shaped profile of the rail 6, instead of on a
leg thereof, and it is also possible to construct the rail 60 as an
angular-profiled rail rather than a U-shaped profiled rail, with
roller 26 engaging behind the up-standing leg of the angular
profile. However, I currently prefer the embodiment illustrated in
FIGS. 8-13 because it is simple in its construction and has been
found to operate perfectly and without any difficulties.
In the previously described embodiments the component 3 can be used
only for concealing purposes (if for instance it is simply a panel)
or as a shelf or the like if it is so constructed. The same is true
of the piece of furniture 2. However, it is desirable to make such
a folding bed unit still more versatile, especially in view of the
fact that it is primarily intended for use in circumstances where
only limited space is available which should be made to yield the
maximum benefit.
In other words, it is desirable that such a unit be capable of
affording other functions of a piece of furniture, beyond those of
merely serving as a repository for the foldable bed when not in
use. In fact, the bed itself should be capable of a wider range of
utilization than merely for night-time sleeping purposes.
This is accomplished, as shown in the embodiments of FIGS. 14-16,
by providing the bed itself in such a manner that it can be
converted into a couch, and advantageously also providing the
component 3 with a foldable table so that when located in
appropriate relationship, that is with the component 3 displaced to
permit the bed to be folded out of the box 4, the bed converted
into a couch and the table and the component 3 together will
constitute a usable seating arrangement.
It is advantageous to so-construct the bed in this case that a
portion of the mattress thereof can be folded upwardly in order to
provide a backrest which is a component part of normal couches.
However, another part of the bed other than the mattress may
similarly be used for this purpose. The component 3 may be provided
with a recess in its outwardly directed surface, the recess being
so dimensioned that the table can be folded in its entirety into
this recess and be flush with the outwardly directed surface of the
component 3, thus avoiding the projection of parts of the table
beyond this surface. The plate of the table, that is the top
thereof, can be made of two or more parts which can be hinged to
one another, thus making it possible to provide a rather large
table top which can be stored in a rather small volume of space.
The legs for supporting such a table top can also be hinged to the
table top and can similarly be folded into a recess provided for
the reception of the table top. Thus, the table will not only
require no space outside the confines of the component 3, but will
when received in the recess provided in the component 3 for its
reception, be scarcely able to provide a visual intrusion.
In FIGS. 14-16 like reference numerals identify the same components
as in the preceding embodiments. The unit in toto is designated in
these Figures with reference characters FB for "folding bed," and
the bed can of course be provided with pivotable supporting legs,
with mattresses and the like as in the preceding embodiments
also.
As indicated in FIGS. 14-15 not only a single piece of furniture 2
may be provided at one lateral side of the box 4, but such pieces
of furniture 2 may be provided at both lateral sides of the box, a
possibility which has already been mentioned earlier. In such a
case the component 3 can then of course be either shifted towards
the left or towards the right to be located as desired before the
piece of furniture at the left-hand side of the box 4 or before the
piece of furniture at the right-hand side of the box 4.
In accordance with the above possibility it is of course necessary
for the guide means for the component 3 to extend to both of the
pieces of furniture 2 if two of them are provided.
The bed 5 is provided with a backrest portion 31 which can be
folded up in the direction of the arrow C as shown in FIG. 15 and
also in the embodiment illustrated in FIG. 16. Normally it will be
located in the general plane of the bed and in order to permit such
folding the portion 31 is provided with a hinge 32 which can be
constructed as an arrangement of the type used in beach chairs or
the like where the portion 31 can be raised or lowered to various
different positions and can be arrested at these different
positions, for instance by providing on the bed 5 a toothed rack
and by providing pins on the portion 31 which are engageable with
the teeth of the rack. Evidently, however, other types of hinges
can also be utilized, that is hinges which are not self-locking. In
the illustrated embodiment the hinge 32 is located at the end of
inwardly drawn brackets of the frame of the bed at the inner pivot
point.
Needless to say, other types of hinges include the possibility of
utilizing a simple hinge and a strap 33 which connects the portion
31 with the frame 34 of the bed 5. Such strap, which could be in
form of a rigid strip of metallic material or could be flexible,
can be connected with the portion 31 in suitable manner.
Bed 5 may also be provided with loose bolsters 35, and instead of
providing the backrest portion 31 a portion of the frame of the bed
may be pivotably arranged. What is essential is that the
possibility of folding up a backrest portion exists over the entire
length of the bed 5 so that the latter can be readily converted
into a couch which can also be used during the day rather than
being restricted to use only for sleeping purposes. As shown in the
embodiment of FIG. 16 the upper edge 36 of the backrest portion 31
may be downwardly and rearwardly inclined to facilitate a folding
of the backrest portion 31 into the frame 34.
In accordance with the invention the component 3 is provided on its
forwardly or outwardly directed side with an open recess 37 in the
interior of which, at the lower end thereof, there is pivotably
mounted a table top 38 which can be pivoted about pivots 39 in the
direction of the arrow D into the recess 37. If the table top is to
be larger than the simple outlines of the recess 37, then the top
may be provided in two portions 38 and 38' which can be connected
with one another by a hinge 40.
In this case the portion 38 is provided at its end which is the
lower end when folded into the recess 37, with legs 41 which can be
pivoted in the direction of the arrow E but which can also be
completely removable if desired. The portion 38' is of box-shaped
configuration on its side which faces downwardly when the table is
folded out of the component 3, so that the legs 41 can be folded
into the interior of the portion 38' when the table is to be folded
up. Of course, the legs 41 may also be of a telescopic type.
When the table is to be folded up out of the position shown in FIG.
14, the legs 41 are first folded in the direction of the arrow E
whereupon the portion 38' is folded in the direction of the arrow F
onto the portion 38, as shown in broken lines in FIG. 14, and the
two portions 38 and 38' are then folded in the direction of the
arrow D into the recess 38 where they may be retained by suitable
retaining arrangements forming no part of the invention.
Here again variations are possible without departing from the
intent and scope of the invention. It is advantageous, from a point
of view of making seating on the bed converted into a couch, more
comfortable, to construct the frame of the bed in such a manner
that the edge portion 34' located opposite the backrest portion
will be lower than the remaining portions of the frame. Quite
evidently, however, it is possible to dispense with this feature
and to make various other modifications.
The embodiments in FIGS. 14-16 make the folding bed unit in
accordance with the present invention vastly more versatile then
anything that is known to me in this art, because the unit in
effect provides for most if not all of the furniture which is
required in a small room, and that it provides a table, a seating
arrangement, storage shelves if desired (for instance in the
furniture pieces 2), a day-use couch and a night-use bed. All of
this can of course be accomplished by simple and rapid conversion
of the unit between its various operational states.
It will be understood that each of the elements described above, or
two or more together, may also find a useful application in other
types of constructions differing from the types described
above.
While the invention has been illustrated and described as embodied
in a folding bed unit, it is not intended to be limited to the
details shown, since various modifications and structural changes
may be made without departing in any way from the spirit of the
present invention.
Without further analysis, the foregoing will so fully reveal the
gist of the present invention that others can by applying current
knowledge readily adapt it for various applications without
omitting features that, from the standpoint of prior art, fairly
constitute essential characteristics of the generic or specific
aspects of this invention and, therefore, such adaptations should
and are intended to be comprehended within the meaning and range of
equivalence of the following claims.
