Abstrict An adjustable bed system or arrangement is provided for positioning
in limited space in a truck-trailer system for ready use by a driver
thereof. This bed arrangement consists of a pair of base plates
pivotally connected together one of the base plates is fixed in
position and the other movable base plate is pivotally mounted to
the fixed plate for angular elevation. A second pair of vertically
spaced plates is mounted below the angularly positioned plate and
the upper plate thereof has a pair of spaced rolls for contact with
the undersurface of the angularly positioned plate. A shaft-cylinder
arrangement is positioned below each roller between the second pair
of vertically arranged spaced plates and each shaft-cylinder arrangement
is elevated by a pressurized reservoir or air bag controlled by
a control valve coupled to a source of air pressure to elevate the
moveable base plate.
Claims What is claimed is:
1. In combination with a truck-trailer system, an adjustable bed
arrangement for use in the limited confinement of a truck-trailer
system, comprising, two base members, one of which is fixed and
the other movable, means for pivotally coupling said base members
together so that one member thereof can be angularly elevated, a
pair of vertically arranged spaced members positioned below said
base member that can be angularly elevated, the upper of said pair
of vertically arranged members having spaced roller members in contact
with the undersurface of said member that can be angularly elevated,
means positioned between said pair of spaced members for elevating
the upper spaced member, and means for applying pressure to said
spaced members to cause said rollers to elevate the angularly elevated
member.
2. An adjustable bed arrangement for use in the limited confinement
of a truck-trailer system as recited in claim 1 wherein the means
for pivotally coupling the fixed and moveable base members together
consists of a piano hinge.
3. An adjustable bed arrangement for use in the limited confinement
of a truck-trailer system as recited in claim 1 wherein the pressure
applying means consists of air source reservoir system.
4. An adjustable bed arrangement for use in the limited confinement
of a truck-trailer system as recited in claim 1 wherein the pressure
applying means consists of a hydraulic system.
Description OBJECTS OF THE INVENTION
It is an object of this invention to provide an adjustable bed
for a truck-trailer transportation system.
Still other objects of this invention are to provide a unique and
novel adjustable bed system for a truck that is economical to manufacture,
use to install and which is efficient and reliable in operational
use.
To provide an adjustable bed system for a truck trailer transportation
system which can be installed in limited space therein is another
object of this invention.
And to provide an adjustable bed system for a truck-trailer arrangement
that is readily available and in proximity of the driver of the
truck-trailer arrangement, is another object of this invention.
BRIEF DESCRIPTION OF THE DRAWINGS
These and other objects and attendant advantages of this invention
will become more obvious and apparent from the following detailed
specification and accompanying drawings in which:
FIG. 1 is a perspective view of an adjustable bed incorporating
features of this invention;
FIG. 2 is a top view of the adjustable bed of FIG. 1;
FIG. 3 is a side view of the adjustable bed of FIG. 1;
FIG. 4 is a side view of the elevating system for the adjustable
bed of FIG. 1; and
FIG. 5 is a end view of the elevating system for the adjustable
bed of FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
Referring now to FIGS. 1 to 5 of the drawings, there is shown
the preferred embodiment of an adjustable bed or bunk arrangement
10 installed, the limited space provided next to and in proximity
with the driver of a truck-trailer transportation system.
This adjustable bed arrangement 10 consists of bases 26 and 28
pivotably connected together by a piano pivot 30. Base 26 is fixed
in position while base 28 is arranged to pivot upwardly as will
be explained thereafter. A mattress M is positioned on the top of
the bases 26 and 28 for a driver to sleep on when the base 28 is
inclined to an angular position.
Two spaced steel plate members 12 and 14 are positioned below the
base 28 for housing the mechanism for elevating the base 28.
Two spaced roller wheels 24 are mounted by U-shaped brackets 25
on the top steel plate 14. Directly below each wheel 24 is mounted
a cylinder 16 and a shaft 18 positioned in the cylinder 16 for supporting
and elevating the vertical plate 14 above the fixed plate 12 so
that the steel base 28 can be angularly elevated as desired. The
upper ends of the shafts are welded to the underside of 14 all
as shown in FIGS. 4 and 5.
As shown in FIGS. 1 to 5 an air bag or air reservoir 20 is positioned
between the two plates or bases 12 and 14. This air bag or air reservoir
is connected by a passageway 22 to a suitable control valve 27 and
a source of pressurized air.
In operational use, the adjustable bed arrangement is put into
operational use by controlling the amount of air through the air
control valve 27. The air is used to pressurize the bag 20 which
causes the upper base 14 to be elevated by the upper movement of
the shafts 18 in their respective pistons 16. When this occurs,
the wheels 24 roll on the back of the base 28 to cause the base
28 to be angularly elevated to the desired height for a proposed
user. When the adjustable bed is no longer to be used, the air is
released through the air control valve 27.
Obviously many modifications and variations of the present invention
are possible in light of the above teachings. It is, therefore,
to be understood that within the scope of the appended claims the
invention may be practiced otherwise than as specifically described.
