The system includes at least one pair of deck panels mounted opposite one another on the side walls of the freight compartment, which are capable of movement between a secure upright position and an extended horizontal deployed position. When the deck panels are in their extended position they at least partially define a platform above the floor of the vehicle freight compartment. The system also includes a support bracket that is secured to each respective deck panel when in the deployed position and adjacent the free end of the deck panels. The bracket has an elongated body, a longitudinally extending channel for engagement with the deck panels and a longitudinally extending support ledge. The longitudinally extending channel interlocks the deployed deck panels and the longitudinally extending support ledge provides support to further pairs of deployed deck panels.
Description
FIELD OF THE INVENTION
The invention relates to intermediate deck structures for use in transport vehicles such as trucks and trailer vans, railway cars, freight containers and the like, and more particularly, to an interlocking deck support system for use in such vehicles.
BACKGROUND OF THE INVENTION
In a typical truck van, a horizontal bed or floor is provided for supporting articles being transported. Articles are placed on this bed, and depending upon the size of the articles, they may be stacked upon each other at two or more levels.
In some instances, it may be impractical to stack the articles due to the weight or configuration. Where this is the case, a substantial amount of the vehicle interior is rendered unusable. For example, where the articles or containers are fragile, damage to the articles will occur if stacked to the extent that the weight of the upper articles would damage lower articles. In those instances, it is often necessary to avoid stacking or to minimize the amount of stacking.
Some articles are also somewhat difficult to handle due to their weight and configuration. This creates problems for the individuals loading the articles on a bed. Thus, even if articles at a lower level will not be damaged when other articles are stacked thereon, stacking itself may be quite cumbersome and inefficient due to the size and weight of the articles.
Attempts have been made to address some of these problems by incorporating intermediate decks in vehicles. Various types of collapsible or removable intermediate deck structures have been proposed for supporting freight articles of various shapes and weights above the horizontal bed or floor of a transport van, and the like, in order to increase the load carrying ability of a van and to maximize the use of the available cubic capacity of a van. The use of collapsible or removable intermediate decks has not met with wide success, however, due to inefficiencies in the design of the decks which make them too complex, too expensive for practical purposes or simply too inconvenient to use.
The design of existing intermediate deck structures often consist of two deck panels, hinge mounted on opposing walls to enable storage of the deck panels vertically against the side walls. The deck panels rotate downwardly or upwardly on the hinges to a horizontal position to form a continuous section of deck, or secondary floor. Typically, this form requires a means of supporting the deck halves horizontally in a manner which both encroaches on additional usable volume for loading the freight or cargo, and interferes with that space requiring extra effort and time to load around it. Such supports include cantilever support structures, suspension chains or cables or even vertical support legs extending to the primary floor.
For example, U.S. Pat. No. 3,911,832 to Vandergriff discloses an intermediate deck structure for use in railway cars, truck and trailer vans. The deck structure includes a first section pivotally connected at its outer end to the side wall of a vehicle, and adapted to be pivoted between a stored position adjacent the side wall and a horizontal position with its inner end extending inwardly from the side wall. A second section of the Vandergriff intermediate deck has a pair of arms extended from its inner end which are pivotally connected to the first section at a point between the inner and outer ends. The second section of the intermediate deck is adapted to be stored adjacent the side wall of the vehicle below the first section of the intermediate deck in a position extending downwardly from the outer end of the stored first section. The second section is adapted to be pivoted relative to the first section during pivoting of the first section to a horizontal loading position, whereby the second section can also be moved to a horizontal loading position with the outer end of the second section supported by a pair of load brackets engaged with a load rail on the opposite side wall of the vehicle.
A problem encountered with the intermediate deck structure of Vandergriff is that the individual deck structures do not lock together when the two deck sections are stored against the side wall of the vehicle, and the load bracket on the second section extends downwardly to a position where it can interfere with and damage cargo and boxes sitting on the main floor of the vehicle. A further problem with the Vandergriff deck is that the load brackets employed in the intermediate deck structure are subject to jumping out of the wall load track rail slots, causing the load brackets to retract under a load on the deck, and dropping the load onto the cargo positioned underneath the intermediate deck.
U.S. Pat. No. 5,452,972 to Adams discloses a deck structure for use in supporting cargo at an intermediate level above the floor or bed of a trailer van. The Adams intermediate deck includes a first deck section pivotally mounted on a side wall of a trailer van and movable to a horizontal load position, and back up to a vertical stored position against the side wall. Adams employs a complex spring slam bolt and release chain system engaged with a height saving angle locking rail to releaseably hold the deck section. A second section of the deck is pivotally connected to the first section and it is also movable between a horizontal load position and a vertical stored position against the side wall. When the second section is in the vertical stored position it is hanging from the first section and is configured such that it nests in the first deck section to provide a storing intermediate deck structure. When the first and second deck sections are in a horizontal load position, the second section has an outer end which is selectively provided with either the spring biased, telescopically mounted load bracket, or a cap style load bracket, that is operatively seated on a load track rail on the trailer van wall opposite to the wall on which the first deck section is hinged. Although the intermediate deck structure of Adams addresses some of the problems of Vandergriff, in doing so it employs complex chain and spring systems that increase the expense of the intermediate deck structure and enhance the risk of injury to the operator of the system. Also, like Vandergriff, Adams fails to address the problem of the lack of structure to lock individual deck structures together.
U.S. Pat. No. 3,875,871 to Thorton discloses a freight carrier such as a railroad car having sections which, unlike the structures in Vandergriff or Adams, fold from opposite walls toward one another from a stored position to an operational position. In the installed position the sections provide a supplementary cargo level. According to Thorton, in this position the sections have joining means which self-support the load and transmit lading shearing and bending moments between the sections so that additional supports from the floor are not required. The deck sections of the Thorton carrier are provided with flanges or blocks for supporting the sections when they are unfolded and for providing a resting space for subsequently lowered sections. Thorton also describes permanent support areas positioned at one end of the freight car designed to provide a resting area for the first lowered panels. The patent describes these rest areas as a bracket or ledge mounted on the rear wall of the carrier by suitable fasteners or welding.
Although Thorton seemingly overcomes many of the problems of Vandergriff and the complexities of Adams, it requires welding structures or fasteners to the interior portion of the carrier to do so. Moreover, although Thorton provides flanges or blocks for supporting subsequent sections, the panels described in Thorton are vulnerable to sag under heavier loads due to inadequate support. Moreover, the flanges or blocks of Thorton subject the panels to interference with one another and, like Vandergriff and Adams, do not interlock the panels together in the operational position.
Consequently, there is a need for a system for supporting articles more efficiently for transportation purposes. In particular, there is a need for such a support system that is of a highly efficient design whereby the deck can be economically installed in a vehicle, each individual intermediate deck can be adequately supported and locked together with other intermediate decks, and the system can be efficiently operated by a single user.
SUMMARY OF THE INVENTION
These and other objects and advantages are met by the present invention which includes a deck support system for supporting cargo in a vehicle freight compartment having spaced apart side walls.
The deck support system includes at least one pair of deck panels mounted opposite one another on the side walls, which are capable of movement between an upright position and a deployed position. Each of the respective deck panels have an end pivotably mounted to the side wall and a free end. When the deck panels are in the deployed position they at least partially define a secondary platform of the vehicle freight compartment when the free ends are adjacent to one another in the deployed position. The deck support system also includes one or more anchors mounted to each of the side walls of the freight compartment to secure the deck panels to the side walls in the upright position.
The system includes a support bracket that removably engages the deck panels adjacent the free ends when the deck panels are in the deployed position. In one embodiment, the support bracket removably engages the deck panels along a side edge of each panel. The support bracket interlocks the pair of deployed deck panels and provides a support ledge for other deck panels. The bracket has an elongated body, which preferably has a rectangular cross section and defines a longitudinal axis. The elongated body has a first side and a second side with a longitudinally extending channel defined in the first side, which is shaped for removable engagement with the pair of deck panels. The elongated body also has a longitudinally extending support ledge defined in its second side. The longitudinally extending channel of the bracket interlocks the deployed deck panels and the longitudinally extending support ledge is capable of providing support to further pairs of deployed deck panels.
In one embodiment, the longitudinally extending channel slidably engages the deployed deck panels and is capable of linear movement perpendicular to the mating faces of the deployed deck panels. In another embodiment, the first side of the elongated body of the bracket is pivotably secured to one of the deck panels of the pair and the longitudinally extending channel pivotably engages the deployed deck panels.
In a preferred embodiment, the deck support system also includes a horizontal starter panel secured at the front of the freight compartment between the side walls and adjacent at least one pair of the deployed deck panels. In this embodiment, a support bracket is secured to the starter panel to support a pair of deployed deck panels adjacent the starter panel.
Advantageously, the deck support system of the present invention supports articles more efficiently than prior art systems for transportation purposes. In particular, the deck support system is lightweight and is of highly efficient design whereby the deck can be economically installed in a vehicle, each individual intermediate deck is adequately supported and can be locked together with other decks, and the system can be efficiently operated by a single user.

DETAILED DESCRIPTION OF THE INVENTION
The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.
Referring to the accompanying drawings,
FIGS. 1-11
illustrate a deck support system, indicated generally at
10
in
FIG. 1
, installed on a truck trailer
12
. The truck trailer
12
is enclosed by side walls
14
, a roof
16
and a floor
18
. While the illustrated embodiment and the following description describe the deck support system of the present invention in conjunction with a truck trailer, the deck support system need not be used in conjunction with a truck trailer, but can instead be used in conjunction with various types of freight transport vehicles or devices such as railway cars, airplanes or transport containers.
As best shown in
FIG. 2
, the deck support system
10
generally includes at least one pair of deck panels
20
and
21
mounted opposite one another on the side walls
14
of truck trailer
12
. The pair of deck panels
20
and
21
are mounted on the side walls
14
by one or more anchors mounted to each of the side walls. In one embodiment, these anchors are horizontal rails
22
that generally run the length of truck trailer
12
. The deck panels
20
and
21
are maintained in their upright position by locks (not shown) provided on the walls
14
of the truck trailer
12
. As shown in
FIGS. 8 and 9
, the deck panels
20
and
21
are fitted with notched mounting brackets
23
that are designed to hook over horizontal rails
22
. In this way, the deck panels
20
and
21
may rotate about horizontal rails
22
between a stored upright position and an extended horizontal deployed position, both as shown in FIG.
2
. The deck panels
20
and
21
have free ends
20
a
and
21
a
, respectively. When the deck panels
20
and
21
are deployed and their respective free ends
20
a
and
21
a
are adjacent, the deck panels
20
and
21
at least partially define a platform in truck trailer
12
above the floor
18
.
The deck support system
10
also includes a support bracket
24
, which is preferably removably mounted between each pair of extended deck panels
20
and
21
to both interlock the pairs of deck panels
20
and
21
together and provide support to the pairs of deck panels
20
and
21
. As shown in
FIG. 3
, the interlocking support bracket
24
has an elongated body and preferably is of a rectangular cross section. The support bracket
24
includes a first side
26
defining a longitudinally extended channel
28
. The support bracket
24
also includes a second side
30
defining a longitudinally extending support ledge
32
.
In the embodiment shown in
FIG. 3
, the longitudinally extending channel
28
has an upper lip
29
and a lower lip
31
. The lips
29
and
31
preferably extend the length of channel
28
. As shown in
FIGS. 4 and 5
, the longitudinally extending channel
28
of support bracket
24
preferably engages the edge of deck panels
20
and
21
by virtue of the upper lip
29
and the lower lip
31
. The upper lip
29
and the lower lip
31
engage a series of grooves in deck panels
20
and
21
. In particular, the deck panel
20
includes an upper groove
33
a
and a lower groove
33
b
, and the deck panel
21
includes an upper groove
35
a
and a lower groove
35
b
. In order to removably and slidably engage the deck panels
20
and
21
, the upper lip
29
of support bracket
24
engages upper groove
33
a
of panel
20
and upper groove
35
a
of panel
21
. Similarly, the lower lip
31
of support bracket
24
engages lower groove
33
b
of panel
20
and lower groove
35
b
of panel
21
. By engaging the deck panels
20
and
21
in this way, the support bracket
24
is capable of linear travel across the faces of deck panels
20
and
21
when the deck panels are deployed. At the same time, the longitudinally extending channel
28
of the support bracket
24
interlocks the deployed deck panels
20
and
21
and the longitudinally extending support ledge
32
provides support to further pairs of adjacent deployed deck panels
20
′ and
21
′ as shown in FIG.
11
. The grooves
35
a
,
35
b
are at least as long as the support bracket
24
, so that the bracket
24
can be stored with the deck panel
21
without protruding past its free end
21
a
.
Referring to
FIGS. 7 through 11
, a secondary platform in truck trailer
12
may be constructed using the above described embodiment of the deck support system
10
by first securing a starter panel
36
to the horizontal rails
22
between the vertical walls
14
and against the forward part of truck trailer
12
as shown in FIG.
7
. Although in this embodiment the starter panel
36
is secured against the forward part of the truck trailer
12
, one of ordinary skill in the art will understand that starter panel
36
may be installed at any location in the trailer
12
where the user desires to start building a secondary platform within the truck trailer
12
. Preferably, starter panel
36
is a continuous shelf that extends between the vertical walls
14
.
A bracket
38
may next be secured to starter panel
36
so that support ledge
32
provides a way to support subsequent deployed deck panels
20
and
21
. The first bracket
38
is preferably rigidly secured to starter panel
36
, but alternatively may be slidably secured thereon such as by a lip and groove design. As shown in
FIG. 8
, after the bracket
38
is in place the deck panel
21
is rotated from its upright position against wall
14
to its deployed position, resting on the bracket
38
. In the alternative, a simple flange may be attached to the forward trailer wall to support the first pair of deck panels to provide the same function as support ledge
32
.
Next, as shown in
FIG. 9
, a support bracket
24
is slid over the deck panel
21
to prepare for the horizontal deployment of the deck panel
20
on the opposite side wall of truck trailer
12
. The support bracket
24
may either stored somewhere on the trailer and be slid over the deck panel
21
(as described) or may be included on the deck panel
21
while the deck panel
21
is in its upright position. As shown in
FIG. 10
, the support bracket
24
is slid onto the deck panel
21
out of the way of the deck panel
20
, and then the deck panel
20
is deployed to its horizontal position. The support bracket
24
is then slid back until it engages both deck panel
20
and deck panel
21
. The support bracket
24
engages the deck panels
20
and
21
by virtue of the engagement of upper lip
29
and lower lip
31
on the support bracket
24
with the upper groove
33
a
and lower groove
33
b
of deck panel
20
, and the upper groove
35
a
and lower groove
35
b
of deck panel
21
.
As shown in
FIG. 5
, preferably the upper grooves
35
a
,
35
b
of deck panel
21
are longer than upper grooves
33
a
,
33
b
of deck panel
20
. Because of this, the support bracket
24
can travel further onto deck panel
21
and completely out of the way of the deck panel
20
. On the other hand, when the support bracket
24
engages the deck panel
20
, preferably it may only travel far enough to provide complete engagement between the deck panel
20
and the deck panel
21
. Thus, after the deck panel
20
is deployed, the support bracket
24
is slid back onto the deck panel
20
so that it slidably engages both deck panels
20
and
21
and locks them together. This process is repeated, as demonstrated in
FIG. 11
, until the desired number of deck panels are extended from their vertical position so that a sufficient amount of secondary platform space is created in truck trailer
12
for the storage of articles.
In another embodiment of the deck support system, shown in
FIG. 6
, the support bracket
24
does not include an upper lip
29
and lower lip
31
and the deck panels
20
and
21
do not include a series of grooves. Instead, the support bracket
24
includes only a longitudinally extending channel
28
and a longitudinally extending support ledge
32
. In this embodiment, support bracket
24
is rotatably secured to one of the two deck panels
20
and
21
of the pair. This may be done, for example, by a pivot pin
34
secured through the first side
26
of support bracket
24
. The support bracket
24
can be rotated into position to interlock the deck panels
20
and
21
when the deck panels
20
and
21
are deployed to the horizontal position, thereby providing the interlocking and support for the deck panels
20
and
21
.
In this embodiment, a secondary platform in truck trailer
12
may be constructed using the deck support system
10
by first securing a starter panel
36
to the horizontal rails
22
between the vertical walls
14
and against the forward part of truck trailer
12
as shown in FIG.
7
. Again, preferably, starter panel
36
is a continuous shelf that extends between the walls
14
. A bracket
38
may next be secured to starter panel
36
so that support ledge
32
provides a way to support subsequent deployed deck panels
20
and
21
. After the bracket
38
is in place, the deck panel
21
is rotated from its upright position against wall
14
, with the support bracket
24
pivotably secured to the panel
21
, to its deployed position, resting on the bracket
38
.
The support bracket
24
is rotated out of the way of the path of rotation of the deck panel
20
to prepare for the horizontal deployment of the deck panel
20
. The deck panel
20
is then deployed to its horizontal position and the support bracket
24
is rotated into position, as demonstrated in
FIG. 6
, so that it engages both the deck panel
20
and the deck panel
21
and provides a support ledge for subsequently deployed deck panels. Again, this process is repeated until the desired number of deck panels are extended from their vertical position so that a sufficient amount of secondary floor space is created in truck trailer
12
for the storage of articles.
