Claims
I claim:
1. A bumper for automotive vehicles in the form of a tool box
closed at the ends and long enough to extend across, and to
protect, a vehicle throughout the entire width thereof, said bumper
comprising a shallow tray portion which includes vertically
disposed, rigid inner, outer and end walls and a rigid horizontally
disposed bottom wall rigidly united with the inner, outer, and end
walls, cover means hingedly mounted on the inner wall for
completing the enclosure, and locking means for retaining the cover
means in closed condition, said cover means comprising a plurality
of independent, hingedly mounted sections with adjacent sections
having parts disposed in lapping relation and the locking means
provided on a single overlapping, dominant section, the
construction and arrangement being such that the locking down of
the dominant section in closed condition may be caused to retain
the entire cover in closed condition.
2. A bumper for automotive vehicles as set forth in claim 1 in
which the cover means consists of two side sections and a dominant
center section, and in which the hinge axes of the side sections
intersect the hinge axis of the dominant center section in such a
way that the bounding edges of opened adjacent sections approach
one another as they swing toward their closed positions, and in
which at least one of each pair of adjacent edges is provided with
offset means engageable with its neighbor for optionally blocking
closure of the involved cover sections and detaining both sections
in open condition.
3. A bumper for automotive vehicles as set forth in claim 1, but
especially of the pickup type, in which the outer faces of the
cover sections are flat and normally occupy a common horizontal
plane, thereby providing a uniform tread surface for loading,
unloading, mounting and dismounting purposes.
4. A bumper as set forth in claim 2 in which the tray portion of
the bumper is completely open at the top and the cover sections
bear directly upon the upper surfaces of the inner, outer and end
walls of the tray portion, and which further includes a pair of
bumper carrying bars adapted for attachment to opposite sides of
the vehicle chassis, said bars being integrally united with the
inner, outer and bottom walls of the tray portion of the bumper and
extending inward through the inner wall for connection to the
chassis.
5. A bumper as set forth in claim 4 in which the carrying bars are
modified to form compartment dividing partitions within the tray,
each adapted to serve as a rest for one margin of the center cover
section and an adjacent margin of a side cover section, and one
channeled to provide a groove in which the working part of a jack
may be snugly cradled.
6. A bumper as set forth in claim 1 in which the outer bumper wall
is formed with an outwardly facing, external central recess, and
the bumper includes trailer tow means accessibly provided in the
recess, and in which the outer bumper wall has further recesses at
opposite sides of the central recess, and safety tow chain
anchorages are provided within said side recesses and extend
completely across the side recesses.
7. A bumper as set forth in claim 6 in which an active electrical
supply socket for trailers is accessibly provided in the central
recess of the outer bumper wall.
Description
This invention relates to automotive vehicles, and more
particularly to pickups, which are notoriously deficient in the
provision of space for conveniently housing tools and
accessories.
It is a primary purpose of the invention to provide a combined
bumper and tool box, adapted to carry a jack, chains and/or other
tools and accessories in an out-of-the-way but conveniently
accessible, theftproof, and relatively quiet manner.
It is a further feature that the box cover, which is heavy, is made
in a plurality of distinct, hinged sections, a first section being
provided with a lock, and normally overlapping a neighboring
section when closed, so that locking down of the first section
locks down the neighboring section as well. Illustratively, a
central section locks down two side sections.
It is also a feature that the hinge axes of adjacent cover sections
intersect one another in such a manner that the adjacent section
edges approach one another as they are swung toward closed
condition, and that provision is made of an offset projection on
one edge of a pair of adjacent cover section edges, so arranged
that the projection may be caused to block closing of both affected
sections, thereby causing the two sections dependably to maintain
one another in open positions.
In accordance with another feature, the bumper is made to include a
pair of carrying bars which are rigidly and directly united with
the inner, lower and outer walls of the bumper tray, and extend
inward through the inner bumper wall for attachment to opposite
sides of the chassis. This contributes importantly to the strength
and rigidity of the bumper, and to the security of its attachment
to the vehicle.
The carrying bars are desirably of less height than the interior of
the bumper, partially divide the interior of the bumper into
compartments, and may jointly serve to maintain a jack in fixed
position.
The outer bumper wall is desirably provided with an external,
central recess in which trailer tow means and a live electrical
supply socket for trailer use are accessibly provided.
Other objects and advantages will hereinafter appear.
In the drawing forming part of this specification, disclosure is
made of presently preferred, practical and advantageous embodiments
of the invention.
FIG. 1 is a fragmentary, perspective view of the rear end of a
pickup having an illustrative box-bumper applied thereto, the
box-bumper being shown empty and in a set, open condition;
FIG. 2 is a fragmentary plan view with the box-bumper closed, but
with the cover partly broken away to reveal a jack in stored
position;
FIG. 3 is a view in rear elevation of the open box-bumper;
FIG. 4 is a plan view of the bumper tray showing details of the
interior structure;
FIG. 5 is a fragmentary view in sectional elevation of a portion of
the bumper tray, the section being taken on the line 5--5 of FIG.
4, looking in the direction of the arrows;
FIG. 6 is a fragmentary view in sectional elevation, the section
being taken on the line 6--6 of FIG. 5, looking in the direction of
the arrows;
FIG. 7 is a fragmentary view in sectional elevation, the section
being taken on the line 7--7 of FIG. 5, looking in the direction of
the arrows;
FIG. 8 is a fragmentary detail view showing how the box-bumper is
supported from the chassis of the pickup chosen for illustration at
a proper level for cooperation with trailer hitches, and for
matching the height of passenger vehicle bumpers;
FIG. 9 is a fragmentary detail view showing particularly one of a
pair of projecting members provided on the side sections of the
cover; and
FIG. 10 is a plan view of the bare outline of a box-bumper of
rounded contour, the bumper being in all other respects like the
bumper of FIGS. 1 to 9.
The novel box-bumper 10 of FIGS. 1 to 9, inclusive, is shown
applied to a pickup 12 of conventional construction. Briefly, the
pickup 12 comprises the usual wheels 14 (one shown), a sprung body
16 which, with a hinged tail-gate 18, defines an open load carrying
tray 20, and a chassis or frame which includes longitudinal side
bars 22 (FIG. 8).
The box-bumper 10, if supported at the level of the bars 22 of the
particular vehicle shown, would be inconveniently high for loading
and unloading, mounting and dismounting purposes, for trailer hitch
purposes, and for matching the height of other bumpers. The
box-bumper 12 is accordingly shown as including at opposite sides
of the vehicle, vertically extending mounting bars or plates 24,
the mounting bars being rigidly secured to the respective chassis
bars 22 in any suitable manner, as by bolt and nut combinations
26.
The bars 24 are made rigidly unitary with horizontal carrying bars
28 and 28a which extend fore and aft and which form partitions,
supports and rigid reinforcements for the tray portion 30 of the
box-bumper 10. The union of the bars 24 with the bars 28 and 28a
may be effected in any suitable manner as by welding or riveting,
and the bars 24 may be varied in length to suit the particular
needs of the vehicle to which the box-bumper is to be applied. In
an appropriate case the bars 24 may even be omitted, and the bars
28 and 28a would then be directly bolted to the chassis members 22
of the vehicle.
The tray portion 30 of the box-bumper shown in FIGS. 1 to 9
includes an inner wall 32, a bottom wall 34, an outer wall 36 and
end walls 38; adjacent walls, as shown, being united by welding.
Spot welding along the edges of the bottom wall 34 is desirable
because it leaves openings for the escape of any water which may
find its way into the tray. This detail is not important, however,
since drain holes of limited size can be provided through the
bottom wall wherever useful. The several walls of the tray could
even be stamped as a single, integral steel forging. Needless to
say, the tray and other parts of the box-bumper are made rustproof
inside and outside as by plating or coating.
The carrying bars 28 and 28a, which are desirably channel bars, as
shown, extend outward through slots formed in the inner wall 32.
They engage the inner wall 32, the bottom wall 34 and the outer
wall 36, and are welded to each of these walls. Neither bar extends
the full height of the tray, each forming a partial partition. The
bar 28 is modified and supplemented by a filler block 40, suitably
secured, as by welding, on its upper surface, the block forming a
rest for cover sections 42 and 44. The other carrying bar 28a is
notched and has its notch partially filled by a reinforcing
channeled member 46 for cradling the operating portion of a jack
45. The interior of the tray desirably has a width to accommodate
comfortably the major dimension of the jack base, so that the jack
is substantially confined against movement. The channeled member 46
is supplemented by blocks 48 and 50, suitably fixed on top of the
bar 28a and made unitary with it as by welding, to provide rests
for adjacent margins of cover sections 44 and 52. As will be
apparent, the tray is divided into three distinct compartments,
arranged to accommodate the jack in the central compartment and in
a minor part of one of the side compartments. The side compartments
may be used for carrying chains and other tools and
accessories.
Between the carrying bars 28 and 28a the bottom wall 34 has an
upward extension 34a which lies in the plane of the inner wall 32
and is welded to it. The inner wall 32 is notched to receive a
vertical portion of a bottom wall member 34a to which it is welded.
The inner wall 32 has substantially greater thickness and strength
than the wall member 34a.
The bottom wall 34, in the bumper chosen for illustration, consists
of four pieces, namely, the horizontal portion of the piece 34a,
side pieces 34b and 34c, and a thicker and stronger center piece
66.
As noted, the tray 30 is provided with a cover consisting of three
sections 42, 44 and 52. The cover sections are independently
mounted through hinges 54 along the upper edge of the inner wall
32. The side cover sections 42 and 52 are provided on their inner
margins with projections 56 which underlie adjacent margins of the
central section 44, so that when the cover sections are closed, the
central section 44 obstructs opening of both of the side sections.
Locking means is provided for the center section 44, consisting
illustratively of a hasp 58 affixed to the section 44 and a
cooperating staple or eye member 60 which projects outward from the
outer wall 36 of the tray. It will be apparent that the center
cover section 44 may be locked closed by means of a padlock,
desirably a combination type of lock, and that the locking closed
of the center section locks closed the side cover sections as well.
With the arrangement described, each cover section will be
comparatively light, and each may be lifted singly, provided the
center section is lifted first, but all may be controlled through
the single locking means provided on, and in connection with, the
center section.
It is desirable, when access to the interior of the box-bumper is
required, that provision be made for detaining two or more of the
tray cover sections dependably in open condition. To this end, the
inner tray wall 32 is not disposed in a single plane. A central
portion of the wall extends directly crosswise of the vehicle, but
the end portions incline outward (rearward when the box-bumper is
provided at the rear of the vehicle as shown). This makes possible
the disposition of the hinge axes of side cover sections 42 and 52
in intersecting relation to the hinge axis of center cover section
44, so that adjacent edges of side and center edges approach one
another as the widely opened cover sections are swung toward their
closed positions. The projections 56 on the side sections are so
shaped that they may be caused to interlock with edge portions of
the center section. All three cover sections are shown as detained
open in this fashion in FIGS. 1 and 3.
The outer bumper wall 36 does not extend straight across from end
to end but is formed with an external recess midway of its length
which is less than half as deep as the full breadth of the tray and
of considerably less length than the length of the central tray
compartment. As shown, this recess is formed by inwardly converging
wall sections 36a and 36c and a central wall section 36b . It is
upon the central wall section 36b that the locking staple or eye 60
is mounted. The central cover section 44 is correspondingly
notched.
The purpose of the recess is to provide accessibly a conventional
tow ball 62 and a conventional electric socket 64 for trailer use.
To provide extra strength and body for the tow ball mount and
reinforcement for the narrowed portion of the box-bumper, the plate
66 is made much thicker and stronger than the remainder of the
bottom wall. The plate 66 extends beneath the mounting bars 28 and
28a, is of a width equal to about one-half the full breadth of the
tray, and is welded directly to the carrying bars 28 and 28a. It is
desirably made about three times the thickness of the bottom tray
wall sections 34a, 34b and 34c.
A plural wire cable 68, leading from the vehicle battery, is
introduced into the central compartment of the box-bumper through a
rubber-grommeted hole 68a in a wall thereof, and terminates at the
socket 64. A conventional pivoted cover 65 is provided for keeping
water out of the socket.
In order to prevent slipping of the jack relative to the bottom of
the bumper when the jack is in use, and in order to assure the
location of the jack near one of the carrying bars 28, 28a,
parallel ribs 72, properly spaced to receive the jack lift between
them, are provided on the lower face of the plate 66, preferably
being welded in place.
Provision is also made of safety tow chain anchorages at opposite
sides of the central recess of the bumper. The outer bumper wall 36
is provided with rectangular openings 74. Just behind each of these
openings a fitting 76 is set. Each fitting has the form of a half
cylinder open at the bottom, comprising an upper, flat,
semicircular wall 78, a semicylindrical lateral wall 80, and a
vertically disposed axial anchoring post 82. The upper wall 78 and
the lateral wall 80 terminate in a common vertical plane, abut the
outer bumper wall 36, and are welded to it. The bottom of the
lateral wall 80 terminates in a horizontal plane, rests on the
plate 66 and is welded to it. The anchoring post 82 is longer than
the lateral wall 80. It extends downward through the plate 66,
fitting through an opening formed in said plate. Each fitting
combines with the plate 66 and the outer wall 36 to form a
semicylindrical recess, with the post extending completely across
the recess. A chain having an intermediate portion passed around
the post and its ends affixed to a trailer cannot accidentally
become detached. The trailer has threefold security against
detachment from the pickup; to wit, the hitch and each of the two
chains. Any one of the three would normally be adequate to prevent
separation.
The box-bumper 10x of Figure 10 is generally like that of FIGS. 1
to 9, differing only in the matter of external configuration. The
outer wall is curved at its ends to form end closures for the tray,
there being no distinct sidewall members. The outer wall is
similarly curved to merge smoothly into the converging,
recess-forming wall portions corresponding to the portions 36a and
36c shown in FIGS. 1, 2 and 4.
I have described what I believe to be the best embodiments of my
invention.
