Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit of U.S. Provisional
Patent Application Ser. No. 61/282,263, filed Jan. 8, 2010.
1. FIELD OF THE INVENTION
[0002] The present invention relates to fitness machines, and more
specifically to a resistance training device configured for easy
transport and assembly to promote exercise.
2. DESCRIPTION OF THE RELATED ART
[0003] A regular exercise program has proven to be a highly
effective way to maintain or increase one's health. However, due to
the hectic demands of today's society, it is oftentimes difficult
to schedule or maintain an exercise program. If time can be found,
one is usually burdened with health club fees and additional
transportation costs.
[0004] One effective method of maximizing one's time for exercise
lies in home exercise equipment. A plethora of home exercise
equipment exists, but most are developed for specific applications
such as abdominal exercisers. While the more specific purposed
exercisers may be effective, not many exists to provide an
effective pectoral workout and/or have limited mobility. Some home
equipment is more robust and allows a wider range of exercises,
such as a Bowflex.TM. machine. However, these types of equipment
require a substantial investment, which many may not be able to
afford. In light of the above, it would be beneficial in the art to
provide an exerciser that can provide an effective pectoral workout
with means for easy stowage and portability.
[0005] Thus, a resistance training device solving the
aforementioned problems is desired.
SUMMARY OF THE INVENTION
[0006] The resistance training device includes a pair of adjustment
rails attached to a door frame by at least two mounting blocks. An
adjustable exercise platform includes a slidable carriage riding on
the adjustment rails to adjustably set the height of the exercise
platform. The exercise platform includes a pair of oppositely
disposed cavities for receiving resistance blocks. The resistance
block provides a predetermined amount of exercise resistance and is
interchangeable with other resistance blocks to vary the
resistance. A pair of pectoral, butterfly handles are insertably
mounted in bores in the support block and the resistance block to
allow the user to perform butterfly exercises. The resistance
training device is easy to assemble/disassemble for storage or
transport.
[0007] These and other features of the present invention will
become readily apparent upon further review of the following
specification and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] The present invention relates to a resistance training
device, generally referred to by reference number 10, which is
configured to maximize pectoral exercises while being convenient
for home, office or abroad. As shown in FIGS. 1, 2 and 4, the
resistance training device 10 includes a pair of adjustment
mounting rails or rods 11 attached in parallel to a header and a
side of a door frame by mounting or anchoring blocks or assemblies
20. An exercise platform 40 slidably mounts to the adjustment rods
11 and may be fixed in the desired position by a pair of clamps 33.
The adjustment rods 11 are angled rods providing the two areas of
adjustable mounting of the anchoring blocks 20, one to the side of
the door frame and the other to the header. Additional anchoring
blocks 20 may be used adjacent either the header, side of the frame
or both for increased stability. Although only one pair of clamps
33 are shown in the Figures, attached to the rods 11 below the
platform 40, additional pairs may be mounted atop the exercise
platform 40. Alternatively, the exercise platform 40 may include
clamping assemblies to fix the position thereof along the
adjustment rods 11.
[0016] As more clearly shown in FIG. 3, each anchoring block 20
includes a base 24 and a pair of movable jaws 21, 22 defining a
C-clamp. The anchoring block 20 may be covered with a layer of
compressible material, both for aesthetics and protection. The base
24 includes a pair of bores 28 for the adjustment rods 11 to permit
the anchoring block 20 to slide thereon. To fix the anchoring
position of the anchoring block 20 on the rods 11, the base 24
includes at least one curved pressure pad inside each bore 28. The
pressure pad 28 conforms to the shape of the adjustment rod 11 and
may be clamped thereto by a wing screw 27 or thumb screw. The
pressure pad 28 may be covered with friction enhancing material or
layer to increase clamping performance.
[0017] Each movable jaw 21, 22 is hinged to the base 24 and moves
or pivots in the direction indicated by arrow 12 in FIG. 3. A
tension spring 29 between the jaws 21, 22 maintains or biases the
jaws 21, 22 in the closed position, as shown in FIG. 3. Opening of
the jaws 21, 22 allows them to be wrapped behind door frame members
or jambs of various dimensions. To ensure that the jaws 21, 22 are
properly hooked onto the door frame member, the distal end of each
jaw 21, 22 includes an appendage or finger having a movable or
pivotable finger pad 23. Each pad 23 is movable or pivotal so that
it may easily hook behind the door frame member or molding. Each
pad 23 may also include a layer or covering to protect the molding
and/or to increase grip thereon.
[0018] To clamp the anchoring block 20 onto the door frame member,
the anchoring block 20 includes a compressible brace 31 attached to
an end of a wing screw 30 or thumb screw. The brace 31 may be made
from relatively elastic material that permits strong clamping
engagement with the door jamb without marring the surface thereof.
Thus, when the anchoring block 20 has been properly adjusted and
mounted, the door jamb is disposed between the pads 23 and the
brace 31 and the anchoring block 20 is clamped to the door jamb by
turning the wing screw 30. It is noted that the brace 31 may be
notched to conform to the interior shape of the door molding.
[0019] Referring to FIGS. 2, 4 and 6, the exercise platform 40 may
be a substantially rectangular block defining a carriage 41. As
with the anchoring blocks 20, the carriage 41 may include a
covering of compressible material for aesthetics and protection.
The carriage 41 includes a pair of bores 43 permitting the carriage
41 to adjustably slide along the adjustment rods 11. The carriage
41 also includes another pair of bores 42 for insertably mounting
the pectoral, butterfly handles 46. Intermediate the top and bottom
ends of the carriage 41, a pair of oppositely disposed cavities 44
are formed congruent with the bores 42. The cavities 44 receive
resistance blocks 50 which provide the desired resistance for the
resistance training device. A spacer brace 45 may be disposed or
formed at the rear of the carriage 41 to brace the exercise
platform against the door jamb. The brace 45 may be a separate
element that is biased against the door jamb in a passive or
selective manner, e.g. compression springs, and/or the brace may be
formed with similar materials to the brace 31 for similar
effect.
[0020] Each butterfly handle 46 may be a substantially J-shaped
member having a handle bar 48 defining the shape. A padded grip 47
is disposed at one end, and the other end of the handle bar 48
includes a split end 49. The padded grip 47 permits the user to
place their forearm thereon while performing the exercise as well
as providing areas for the user to grip.
[0021] The resistance training device 10 includes interchangeable
resistance blocks or plugs 50 for selectively defining the
resistance of the device 10. The user may be provided with a
plurality of resistance block sets, each set having a resistance
different from the other. As shown in FIG. 5, each resistance block
50 may be a substantially solid cube having a cylindrical core 51,
the cubes being mounted in cavities in the platform 40 so that the
cubes do not rotate. The cylindrical core 51 is split to form
semi-cylindrical hollow through holes or bores 53. These bores 53
are adapted to receive the slotted split end 49 of a respective
butterfly handle 46 to form a male/female connection thereby. When
the split end 49 is connected to the core 51, rotation of the
handle 46 concurrently rotates the core 51.
[0022] In the preferred embodiment, the cylindrical core 51 is
integral inside the resistance block via integral springs 52. The
springs 52 bias the core 51 in one direction such that turning the
handle 46 in the opposite direction requires the user to act
against the bias or resistance of the springs 52. As an
alternative, the leaf-like coil spring 52 may be replaced with a
torsion spring surrounding the core 51 and securely attached to the
interior of the resistance block 50. As a further alternative, the
resistance block may be made from durable rubber with the two
semi-cylindrical through holes or bores 53 formed thereon. The
central partition between the bores 53 would be substantially
increased in durability such that during operation, the central
partition may deform without breaking. It is noted that in all
instances, any durable material with limited deformation
characteristics may be used to make the resistance block 50 with
the desired resistance. To ensure long lasting operation of the
resistance training device 10, the distal end of the split end 49
may be covered by a reinforced cap 13 to minimize or prevent
deformation of the split end 49.
[0023] The following describes how to use the resistance training
device 10. To ready the training device 10, the user mounts one of
the anchoring blocks 20 to a door jamb as noted above. The pair of
adjustment rods 11 are threaded through bores 28 in the mounted
anchor block 20 and clamped via pressure pads 26. The exercise
platform 40 is slidably mounted to the adjustment rods 11 and
clamped at the desired height by clamps 33. The other end and the
header area of the adjustment rods 11 are then secured to the door
jamb by additional anchoring blocks 20. Pre-selected resistance
blocks 50 are installed in the cavities 44 formed in the exercise
platform 40. Then the butterfly handles 46 are insertably mounted
through the bores 42, 53 and the resistance training device is
ready for use.
[0024] As noted above, exercise is a great health benefit for
everyone. The pectoral muscles are one of the major muscle groups
that with regular exercise, will help burn more calories and reduce
weight. As such, the resistance training device 10 provides an
effective workout for the pectorals, and due, in part, to
relatively few parts and low complexity, the resistance training
device 10 may be easily assembled/disassembled for storage and
transport.
[0025] It is noted that the resistance training device 10 may
encompass a variety of alternatives. For example, the coverings
mentioned above may be comprised of vinyl, rubber, composites or
other similar materials. The rods 11 and the handle bars 48 may be
made from durable yet relatively lightweight metals to increase
portability. The resistance training device 10 may be colored
and/or include indicia.
[0026] It is to be understood that the present invention is not
limited to the embodiments described above, but encompasses any and
all embodiments within the scope of the following claims.
