Description
FIELD OF THE INVENTION
[0001] The present invention generally relates to weight training
sleds, and in particular to such devices which are reconfigurable
for different exercises.
BACKGROUND OF THE INVENTION
[0002] Physical training equipment comes in many functional
variations, one of which is a weight sled. Weight sleds are
typically supported on runners which provide friction with a
support surface against which work is performed by pushing the sled
for muscle strengthening. As training methods evolve and become
more sophisticated to train different muscles using different
methods and equipment, the types and different pieces equipment
increase. Thus, multi-use equipment has proliferated for providing
the correct type of exercise for different muscles while using only
a single piece of equipment. The value of multi-use training
equipment is well recognized.
SUMMARY OF THE INVENTION
[0003] One embodiment of the present invention provides a weight
training sled, comprising: a frame having a front end and a rear
end; a first member adapted for temporarily attaching weights to
the frame; a pair of rear runners and a pair of front runners
attached to the frame and extending downward from the frame; two
pairs of upward facing receptacles including a rear pair of
receptacles and a front pair of receptacles; and a pair of
elongated members each adapted to individually engage each
receptacle and extend upward from the frame.
[0004] The sled may further comprise an axle attached to a front
end of the frame and adapted for rotatable mounting of a common
circular barbell weight to the frame as a wheel for the frame. The
front axle may be mounted to the frame forward from the front pair
of runners. The sled may further comprise an inverted u-shaped
member mounted to the frame in proximity to opposing ends of the
axle and extending upward, allowing clearance for a common barbell
weight mounted on the axle by the u-shaped member. The sled may
further comprise a pair of rearward facing receptacles mounted to
the frame and each adapted to engage an individual elongated member
with the engaged elongated member extending rearward from the
frame, to form a lifting handle for the rear end of the frame. The
rearward facing receptacles may be angled outward towards the rear
of the frame to provide increasing separation between elongated
members engaged in the rearward facing receptacles with increasing
distance from the frame.
[0005] The sled may further comprise a pair of rearward facing
receptacles mounted to the frame and each adapted to engage an
individual elongated member with the engaged elongated member
extending rearward from the frame, to form a lifting handle for the
rear end of the frame. Each of the upward facing receptacles of the
two pairs of receptacles may attach a separate runner to the frame.
The elongated members may be located in either the rear pair of
receptacles or the front pair of receptacles to allow the sled to
be pushed either toward the front end of the sled or toward the
rear end of the sled, respectively. The frame may include a pair of
parallel interconnected members extending forward and rearward in
the frame. The first member may be elongated and is mounted
extending upward from the frame to engage central holes in common
circular barbell weights to carry the weights on the frame. The two
pair of upward facing receptacles and the elongated members may be
adapted to engage snugly to transmit horizontal force from the
elongated members to the frame. The front pair of receptacles and
the rear pair of receptacles may have different spacing between
their individual receptacles to provide different spacing between
elongated members mounted in each pair
[0006] Another embodiment of the present invention provides a

frame; and a pair of elongated members each adapted to individually
engage each rearward facing receptacle and to extend rearward from
the frame, wherein individually engaging the pair of elongated
members in one of the pair of rearward facing receptacles with a
common circular barbell mounted on the axle forms a
wheelbarrow-like training device.
[0007] The rearward facing receptacles may be angled outward
towards the rear of the frame to provide increasing separation
between elongated members engaged in the rearward facing
receptacles with increasing distance from the frame. The device may
further comprise an inverted u-shaped member mounted to the frame
in proximity to opposing ends of the axle and extending upward,
allowing clearance for a common barbell weight mounted on the axle.
The device may further comprise a pair of upward facing receptacles
with each individual receptacle mounting one of the pair of rear
runners to the frame, wherein the upward facing receptacles are
adapted to engage one of the elongated members and couple
horizontal force from elongated members engaged therewith to the
frame. The first member may be elongated and is mounted to extend
upward from the frame to engage central holes in common circular
barbell weights to carry the weights on the frame.

DETAILED DESCRIPTION OF THE DRAWINGS
[0016] FIG. 1 shows a weight training sled 10 generally including a
frame 12, two pairs of push handles 14, 16 a pair of lift handles
18, and a vertical member 20 adapted for mounting common circular
barbell weights on frame 12. Also included are two pairs of runners
22, 24 mounted to extend downward from frame 12 for supporting sled
10 on a surface. Runners 22, 24 are mounted to frame 12 by two
pairs of upwardly facing receptacles 26, 28, respectively.
Receptacles 26, 28 have a circular cross section and are sized to
receive the handles 14, 16 in a secure frictional fit to allow the
transfer of horizontal force from handles 14, 16 to frame 12. Any
suitable means may be used for attaching runners 22, 24 to frame
12. The use of receptacles 26, 28 for this purpose is preferred for
efficiency.
[0017] Also attached to frame 12 are a pair of rearward facing
receptacles 30, which are adapted to receive lift handles 18.
Receptacles 30 include a pair of pop pins 31 used for securing lift
handles 18 into receptacles 30. Further attached to frame 12 is a
horizontal axle 32 adapted for mounting a common circular barbell
weight 33 (FIG. 3) as a wheel for sled 10. Also mounted to frame
12, just behind axle 32, is an inverted u-shaped member 34. Axle 32
is held to frame 12 by a pair of hubs 35, 36, the latter of which
includes a pop pin 37 for retaining axle 32.
[0018] FIG. 2 shows a bottom view of sled 10, which includes a
front end 40 and a rear end 42, with axle 32 mounted at front end
40 and receptacles 30 mounted at rear end 42 and facing rearward so
that lift handles 18 extend rearward and outward from frame 12.
Frame 12 generally includes a pair of parallel elongated members 44
extending between front end 40 and rear end 42. Elongated members
44 are interconnected by a plurality of cross members 46, 47, 48
and 49. Cross member 46 is also used for mounting the rear pair of
upward facing receptacles 28 and one end of receptacles 30 to frame
12. Cross member 47 is also used for connecting another end of
rearward facing receptacles 30 to frame 12. Cross member 48 is also
used for connecting upward extending member 20 (FIG. 1) to frame
12. Cross member 49 only serves as a structural connection between
elongated members 44. Elongated members 44 are further
interconnected near the front end 40 by means of inverted u-shaped
member 34 (FIG. 1), which extends upward from frame 12 to provide
clearance for a circular barbell weight 33 mounted on axle 32.
[0019] Two noticeable aspects in FIG. 2 are that the front pair of
runners 22 are mounted more closely that the rear pair of runners
24, and that the rear facing receptacles 30 are angled outward
towards the rear end 42. This angular mounting provides angular
orientation for lift handles 18 so that their separation increases
with distance from the sled. Another feature is that axle 32 is
mounted in from of the front pair of runners 22.
[0020] Push handles 14, 16 and lift handles 18 are intended to be
substantially the same and formed as elongated members each of
which is adapted to fit in one of the different pairs of
receptacles 26, 28 and 30. In this manner, frame 12 is preferably
sold and used with just two pairs of handles 14, 16, 18, even
though a single pair of handles may be used together in any one
pair of receptacles 26, 28, 30. The use of two pairs of handles
14,16,18 is preferred as shown in the configuration of FIGS. 3 and
5. The ability to remove and relocate the pairs of handles 14, 16
and 18 allows sled 10 to be conveniently packaged and shipped
because vertical member 20 is only bolted to frame 12. Bolting is
sufficient even though weights are located on and around member 20.
Thus, frame 12, member 20 and one pair of handles 14, 16, 18 may be
easily packed in relatively flat box and without the extra weight
of two of the pairs of handles. Circular barbell weights do not
need to be shipped with sled 10 because users typically already
have such common weights. The common weight in the industry is just
a circular weight having a 2'' (50 cm) center hole, such as those
used in the Olympics.
[0021] FIG. 3 shows a side view of weight training sled 10 used
with two pairs of handles 14,18, wherein the rear pair of handles
16 (FIG. 1) has been relocated to the receptacles 30 to act as lift
handles 18. FIG. 3 also shows the mounting of a common circular
barbell weight 33 on axle 32. These two features of FIG. 3 provide
a wheelbarrow configuration to sled 10. Additional circular barbell
weights would be added to member 20 to increase the work load.
[0022] FIG. 3 also demonstrates the small side profile of frame 12
when handles 14, 16, 18 and member 20 are removed from frame 12.
Also demonstrated is the placement of axle 32 forward from runner
26, which provides ground clearance for runner 26 when a common
circular barbell weight is attached to axle 32 as a wheel.
[0023] FIG. 4 is a front end view of sled 10 demonstrating the
difference in separation between handles 14 and handles 16.
[0024] FIG. 5 is a perspective view of sled 10 configured simply as
a push sled that can be pushed either from the front or rear.
Handles 18 (FIG. 1) have been removed and a common circular barbell
weight 50 has been located on member 20. The common circular
barbell weight 50, as referred to in this application is simply a
widely used size of approximately 17.7'' in diameter with a center
hole of approximately 2'' diameter, FIG. 5, except for weight 50,
also shows the standard shipping components of sled 10 with two
pairs of handles 14,16, which may be reconfigured for the
wheelbarrow arrangement of FIG. 3. Sled 10 is sized to allow use
with common barbell weights, which users would normally have
available.
[0025] In use, sled 10 may be easily set up and reconfigured as
needed. The only assembly required is the bolting of elongated
member 20 to cross member 48, and he bolting of u-shaped member 34
to frame 12. Any common circular barbell weights 33,50 may be
loaded on to member 20. The weight load can vary from none to about
six weights or approximately 300 pounds. Pairs of handles 14, 16,
18 may be located in any pair of receptacles 14, 16, 18.
Receptacles 14, 16 use a frictional fit sufficient of transmit
horizontal force from handles 14, 16 to frame 12. Receptacles 30
are longer and use a looser fit, relying upon pop pins 31 to retain
handles 18.
[0026] Receptacles 26, 28 are intended to enable use of sled 12 as
a push sled that can be pushed either toward front end 40 or rear
end 42. Placing handles in the rear pair of receptacles 28 enables
the sled to be pushed in its forward direction, and placing the
pair of handles in the front pair of receptacles 26 enables the
sled to be pushed in its rear direction. The function difference
between the pairs of receptacles 26, 28 is their difference in
spacing which accommodates different sizes of athletes and allows
for some variation in the muscles used by the athlete. Sled 10 may
also be easily reconfigured by simply relocating a single pair of
handles between pairs of receptacles 26 and 28. The inverted
u-shaped handle 34 may also be used for pushing sled 10.
[0027] A further easily reconfiguration of sled 10 is into the form
of a wheelbarrow. The is accomplished by pulling pop pin 36 and
removing axle 32 from hubs 35-36. A common circular barbell weight
may be located between hubs 35-36. And the axle 32 slid through the
standard central hole in the barbell weight. The front end 40 of
frame 12 may be lifted slightly by the use of u-shaped handle 34,
as needed. The pair of handles is then located in the rear facing
receptacles 28 as shown for lift handles 18 and secured with pop
pins 31. Lifting force may then be applied to handles 18 for a
wheelbarrow exercise. The location of axle 32 in front of runners
22 allows runners 22 to clear the ground when the rear end 42 is
elevated. The angled lift handles 18 cause the spacing between them
to change with distance from frame 12 and thus enable the
accommodation of different sized athletes.
[0028] The present invention is introduced using examples and
particular embodiments for descriptive purposes. Although a variety
of examples are presented to show how various configurations can be
employed to achieve the desired improvements, these particular
embodiments are only illustrative and not intended in any way to
restrict the inventions presented.
