Description
BACKGROUND OF THE INVENTION
Athletic benches are widely used in a variety of sports ranging from
football to soccer. Usually, athletic benches, or benches occupied by
players during the course of an athletic contest, come in different sizes
and designs. Many such benches are made of wood or metal. However, most
athletic or player benches share one common characteristic. They are
usually large and far from portable. Such conventional player benches are
generally functional. But their size and weight restrict their use to
essentially one location.
Certain athletic fields such as soccer fields or baseball fields typically
used by children or young adults are not provided with player benches.
Thus, those players not actually participating usually stand or kneel on
the sidelines. This is not an ideal situation, especially for players
taking a break from the athletic action.
Therefore, there has been and continues to be a need for a foldable bench
that can be folded and carried from on location to another.
SUMMARY OF THE INVENTION
The present invention entails a foldable bench having at least two seat
sections and an underlying support structure. The underlying support
structure includes at least two leg assemblies that are foldable from a
folded or retracted position to an extended position. In the extended
position the leg assemblies are interconnected by a pair of connectors.
Further, the leg assemblies are interconnected by a cable or other
interconnecting member.
In one preferred embodiment, when the foldable bench assumes an erect and
unfolded position, the connectors extending between the bench and the leg
assemblies are maintained in compression while the cable or
interconnecting member extended between the leg assemblies is maintained
in tension.
Other objects and advantages of the present invention will become apparent
and obvious from a study of the following description and the accompanying
drawings which are merely illustrative of such invention.

DESCRIPTION OF THE INVENTION
With further reference to the drawings, the foldable bench of the present
invention is shown therein and indicated generally by the numeral 10. As
will be appreciated from subsequent portions of this disclosure, the
foldable bench 10 is adapted to assume a folded position, as shown in FIG.
1, or an unfolded or erect position as shown in FIG. 2.
Viewing the foldable bench 10 in more detail, the same includes a pair of
seat sections, each seat section being indicated generally by the numeral
12. It should be appreciated that the foldable bench 10 could include any
number of seat sections 12 but in the case of the embodiment illustrated
herein, the foldable bench includes two seat sections. Each seat section
includes a top 12A and a bottom 12B. Seat sections 12, and other portions
of the foldable bench 10, can be constructed of various materials such as
plastic, wood, metal, fiberglass, etc.
To support the foldable bench 10 when the same assumes the unfolded or
erect position shown in FIG. 2, there is provided an underlying support
structure. This underlying support structure includes a pair of leg
assemblies of 20, each leg assembly being foldable and mounted to the
underside 12B about the outboard portion of each seat section 12.
Connected between the inboard portions of the seat sections 12 is a hinge
assembly 22. As will be appreciated from subsequent portions of the
disclosure, the hinge assembly 22 permits the seat sections to be folded
back-to-back as shown in FIG. 1 or to be extended to where the seat
sections lie end-to-end and generally within the same plane. A strut or
first connector indicated generally by the numeral 24 is connected between
each leg assembly 20 and the hinge assembly 22. As will be appreciated
subsequent herein, when the foldable bench 10 is unfolded and assumes the
erect position of FIG. 2, the individual connectors 24 are in compression
when a load is applied to the erected bench 10. In addition, a cable or
interconnecting member 26 is connected between the leg assemblies 20. In a
preferred embodiment, the interconnecting member assumes the form of a
flexible cable 26. However, it is appreciated that the interconnecting
member 26 could simply be a rigid rod, shaft or even a telescoping member.
With reference to FIGS. 3A-4B, the leg assembly 20 is shown in more detail
therein. Each leg assembly mounted to the outboard end of a seat section
12 includes a bracket or mounting plate 30 that is secured to the
underside of a respective seat section by bolts, screws or other suitable
means. Formed on each side of the bracket is pair of spaced apart gussets
32. A leg 34 is pivotally mounted between each pair of gussets 32 by a
pivot pin 36. In the case of the present embodiment, pivot pin 36 assumes
the form of a bolt and nut assembly. Extending across and between the legs
34 is a cross member 38. Secured or formed on the inside of the cross
member 34 is a stub sleeve 40 that as will be understood later, functions
to connect to one end of the connectors 24. Extending from the central
portion of the cross member 38 is a tab 42 that is adapted to connect to
one end of the cable 26.
As seen in FIGS. 4A and 4B, the entire leg assembly 20 can be pivoted via
the pivot pins 36 from an extended position (FIG. 4A) and a retracted or
folded position (FIG. 4B).
With specific reference to FIGS. 2 and 5, the hinge 22 for connecting the
seat sections 12 is shown. Hinge 22 includes a pair of brackets 50 and 52,
each bracket being secured to the underside 12B of a respective seat
section about an inboard end. One of the brackets, in this case, bracket
50 includes two sets of hinge fingers, with each hinge finger being
referred to by the numeral 56. On the other bracket 52, there is provided
a pair of spaced apart hinge fingers 58. A seen in FIG. 5, the single
hinge fingers 58 project into and between a pair of the hinge fingers 56
formed on the opposite bracket 50. All of the hinge fingers 56 and 58
includes openings for receiving a pivot pin 60. In this case, each pivot
pin 60 includes a bolt and nut assembly.
Therefore, it is seen that the seat sections 12 can be pivoted about the
axis of the two pivot pins 60. In one configuration, the foldable bench
assumes a folded position (FIG. 1), and in another configuration the bench
sections 12 assume an extended position and wherein, as viewed in FIG. 2,
the hinge assembly 22 also is extended.
Finally, each of the brackets 50 and 52 of the hinge assembly include a
pair of connector gussets 62. As seen in FIG. 5, each pair or set of
connector gussets 62 is generally centrally located with each gusset
including an opening formed in the outer terminal end.
Pivotally connected to the connector gussets 66 is the connector 24. A
pivot pin 70 in the form of a bolt and nut assembly is extended through
the openings within the terminal ends of the gussets 62 and through an
opening in one end portion of the connector 24. The other end of the
connector 24 is adapted to be inserted into the stub sleeve 40 of one of
the leg assemblies 20. This is particularly illustrated in FIG. 4A. When
the foldable bench 10 assumes the unfolded or erect position, it is
desirable to lock or secure each connector 24 to a respective leg assembly
20. Therefore, there is provided a locking pin or screw 72 that is adapted
to be secured to both the outer end of each connector 24 and a respective
stub sleeve 40. The locking pins or screws 72 can be easily and quickly
attached and detached to facilitate the folding of the bench 10.
Further, the leg assemblies 20, in an erect position, are interconnected by
a cable 26. It is noted that the cable 26 is secured to the leg 20 by
connecting to the tabs 42 extending from the cross member 38. Cable 26 can
be connected to the tabs in various ways. For example, the opposed
terminals ends of the cable 26 can be secured to a bolt assembly which is
in turn connected to an opening formed in the tab 42.
In the folded position, as seen in FIGS. 1 and 4B, the leg assemblies 20
are rotated to where the legs 34 point towards the hinge assembly 22. The
underside of each seat section 12 includes a recess or cavity 12C that
receives a portion of the leg assembly 24. In the case of the embodiment
illustrated herein, the recess or cut-out 12C is particularly adapted to
receive at least a portion of the cross member 38 and the stub sleeve 40
and tab 42 that are associated with the cross member 38. This tends to
make the bench 10 more compact when the same assumes the folded position.
When the bench 10 is extended to its erect position shown in FIG. 2, it is
appreciated that the length of the connectors 24 and the cable 26 is
calculated so as to result in the legs of the leg assemblies being
directed inwardly at an angle. That is, in the preferred embodiment, the
leg assemblies 20 and particularly the legs 34 thereof are not disposed
perpendicular to the seat sections 12 but are disposed at an angle as
illustrated in FIG. 2. While this angle may vary, in one exemplary
configuration, the legs 34 form an angle of approximately 20 degrees with
respect to a reference line that extends through the pivot pins 36 and
normal to the seat sections 12. It is contemplated that the angle of the
legs 34 with respect to the reference line could vary from 10 to 20
degrees. Further, each strut or connector 24 would preferably extend
generally normal to the attached leg assembly 20. That is, each strut or
connector 24 would form a generally right angle with respect to the leg
assembly 20.
Further, when the foldable bench 10 is disposed in the erect position shown
in FIG. 2, and a load is placed on the bench 10, the connectors 24 are
generally held in compression. Cable 26, on the other hand, is maintained
in tension and thus prevents the legs from rotating outwardly in response
to a load being placed on the bench.
Finally, the folded bench 10 may assume various configurations and designs.
In one particular embodiment, the interconnecting member 26, as discussed
above, could be in the form of a cable and the cable could be utilized as
a carrying strap for the entire bench 10 when the same assumes the folded
configuration. Additionally, in the embodiments illustrated herein, the
bench is shown as including two seat sections 12. However, it will be
appreciated that the foldable bench 10 could include more than two
foldable sections.
The present invention may, of course, be carried out in other specific ways
than those herein set forth without departing from the scope and the
essential characteristics of the invention. The present embodiments are
therefore to be construed in all aspects as illustrative and not
restrictive and all changes coming within the meaning and equivalency
range of the appended claims are intended to be embraced therein.
