Description  |

BACKGROUND OF THE INVENTION
Although pickup trucks are constructed in generally two sizes so as to be
provided with either 61/2foot load beds or 8 foot load beds, there are
many instances when the owner of a pickup truck wishes to carry a long
load in the load bed of his truck and many times such a long load projects
considerably rearwardly of the free edge of the tailgate when the tailgate
is in the lowered rearwardly projecting position.
Such long loads present a problem if they project considerably beyond the
rear marginal edge of the tailgate inasmuch as the rear portion of the
long load tends to fall downward toward the ground when at least a major
portion of the length of the load is not disposed forward of the rear
marginal edge of the tailgate.
The extension of the instant invention may be constructed of various sizes
but in most cases an extension of 30 inches is sufficient to enable
considerably longer loads to be carried on a pickup truck. Actually, an
extension of 30 inches enables approximately a 5 foot longer load to be
carried by the pickup truck.
SUMMARY OF THE INVENTION
The tailgate extension of the instant invention has been constructed in a
manner whereby it may be readily adjusted for attachment to pickup truck
load beds of different widths. Further, the extension is constructed in a
manner whereby its attachment to an associated pickup truck will require
only slight modifications to the pickup truck.
The main object of this invention is to provide a horizontal rearward
extension of the lowered tailgate of a pickup truck to thereby enable that
pickup truck to carry substantially longer loads in the load bed thereof.
Another object of this invention is to provide a tailgate extension in
accordance with the preceding objects and constructed in a manner whereby
it may be readily adjusted so as to be adaptable to pickup truck load beds
of varying widths.
Another important object of this invention is to provide a tailgate
extension which may be readily mounted upon and removed from an associated
pickup truck with little effort and through the utilization of only simple
hand tools.
An important object of this invention is to provide a pickup truck tailgate
extension which may be mounted on an associated pickup truck with only
slight modifications of the pickup truck being required.
A final object of this invention to be specifically enumerated herein is to
provide a tailgate extension in accordance with the preceding objects and
which will conform to conventional forms of manufacture, be of simple
construction and easy to use so as to provide a device that will be
economically feasible, long lasting and relatively trouble free in
operation.
These together with other objects and advantages which will become
subsequently apparent reside in the details of construction and operation
as more fully hereinafter described and claimed, reference being had to
the accompanying drawings forming a part hereof, wherein like numerals
refer to like parts throughout.

DETAILED DESCRIPTION OF THE INVENTION
Referring now more specifically to the drawings the numeral 10 generally
designates a conventional form of pickup truck including a rear load bed
referred to in general by the reference mumeral 12 and including a floor
14 and upstanding opposite side walls 16 and 18 between which the floor 14
extends. In addition, the load bed 12 includes a tailgate 20 of
conventional design including inner and outer marginal edges 22 and 24 and
with the inner marginal edge 22 pivotally supported from the rear marginal
edge 26 of the floor 14 for oscillation of the tailgate 20 between the
horizontally rearwardly directed position thereof illustrated in FIG. 1
and an upstanding position extending between the rear upstanding edge
portions of the side walls 16 and 18, an articulated brace assembly 28 of
conventional design being secured between each side edge of the tailgate
20 and the corresponding side wall of the load bed 12.
The above description comprises a description of a conventional form of
pickup truck.
The extension of the instant invention comprises a generally horizontal
extension panel assembly referred to in general by the reference numeral
30 and including a pair of opposite side front-to-rear extending angle
memebers 32 and 34 interconnected by means of front, intermediate and rear
transverse braces 36, 38 and 40 extending and secured therebetween. The
brace 36 extends between the front ends of the angle members 32 and 34,
the rear transverse brace 40 extends between the rear ends of the angle
members 32 and 34 and the intermediate transverse brace 38 extends between
the longitudinal mid-portions of the angle members 32 and 34. Each of the
transverse braces includes a small dimensioned angle member 42 secured to
the angle member 34 and projecting toward the angle member 32 and also a
large dimensioned angle member 44 secured to the angle member 32 and
projecting toward the angle member 34. The ends of the angle members 42
and 44 remote from the angle members 34 and 32 are overlapped and provided
with selectively registrable bores 45 and 46 at opposite ends thereof
through which fasteners 48 are secured. Thus, the effective spacing
between the angle members 32 and 34 may be adjusted. In addition, each
side of the panel assembly 30 includes a pair of angle members 50 which
are secured to and extend along the upper flanges of the angle members 32
and 34, fasteners 52 being utilized to secure the horizontal flange
portions of the angle members 50 to the horizontal flange portions of the
angle members 32 and 34. The forward ends of the support arm defining
angle members 50 project considerably forwardly of the opposite ends of
the forward transverse brace member 36 and a panel 54 is secured at its
four corners to the opposite ends of the transverse braces 36 and 40 by
means of suitable fasteners 56 removably secured through corner apertures
58 in the panel 54 and apertures 60 formed in the corresponding ends of
the angle members 42 and 44.
Of course, if the width of the frame defined by the angle members 32 and
34 and the transverse braces 36, 38 and 40 is varied, a panel 54 of
different width will be utilized.
A pair of forwardly and upwardly inclined angle member braces 62 have their
rear lower ends secured as by fasteners 64 to the rear end portions of the
upstanding flanges of the angle members 50 and the upper forward end
portions of the braces 62 are braced relative to the forward ends of the
support arms defined by the angle members 50 by means of vertical braces
66 secured between the upper ends of the braces 62 and the forward end
portions of the angle members 50. In operation, the panel assembly 30 is
disposed immediately to the rear of the open tailgate 20 in the manner
illustrated in FIGS. 1 and 2 of the drawings and the upper forward
terminal ends of the braces 62 are secured to the upper ends of the rear
upstanding edges of the side walls 16 and 18 by means of removable
fasteners 68. The forward terminal ends of the support arms defined by the
angle members 50 are secured to the lower ends of the upstanding rear
marginal edges of the side walls 16 and 18 by means of removable fasteners
70 and the forward ends of the horizontal flanges of the angle members 50
are shortened and downwardly deflected as at 72 to define depending
flanges which are downwardly telescoped into the opposite ends of the slot
74 defined between the rear marginal edge 26 of the flooring 14 and the
inner marginal edge 22 of the tailgate 20. Further, the forward ends of
the vertical flanges of the angle members 32 and 34 abut against the outer
marginal edge 24 of the tailgate 20 at the opposite sides thereof. In this
manner, the panel assembly 30 is securely supported from the load bed 12
and may support considerable weight thereon. Of course, the fasteners 68
and 70 may be readily removed with minimum of effort and through the
utilization of simple hand tools and therefore the panel assembly 30 may
be quickly remvoed from the pickup truck 10 and stored whenever the panel
assembly or extension 30 has served its purpose.
The foregoing is considered as illustrative only of the principles of the
invention. Further, since numerous modifications and changes will readily
occur to those skilled in the art, it is not desired to limit the
invention to the exact construction and operation shown and described, and
accordingly all suitable modifications and equivalents may be resorted to,
falling within the scope of the invention.
