Description
PRIORITY CLAIM
[0001] This application claims priority to U.S. Provisional
Application Ser. No. 60/566,853, filed Apr. 30, 2004.
BACKGROUND OF THE INVENTION
[0002] The present invention relates to an exercise apparatus, and
more particularly to an exercise bench whose vertical position can
be adjusted infinitely between two end points.
[0003] Exercise devices of many types are known, including exercise
devices which have a so-called bench which is used in combination
with various other types of exercise components for exercising
different parts of the body. Examples of such benches are those
sold under the Universal.RTM. and Nautilus.RTM. trademarks. The
problem with such conventional benches is that they are either
fixed as to either their height off the ground or, if they are
adjustable, the adjustment is only possible in fixed increments.
This presents a drawback to these prior art benches since a user
must settle for either a fixed height of the bench or one of the
preselected heights when using the exercise equipment. This
"settling" compromises the efficiency, safety, and benefits to the
user when using the exercise equipment since it is not optimally
adjusted or adjustable to his or her stature.
SUMMARY OF THE INVENTION
[0004] Accordingly, it is an object of the present invention to
provide an exercise bench construction that is infinitely
adjustable between two end positions.
[0005] Pursuant to this object, and others which will become
apparent hereafter, one aspect of the present invention resides in
an exercise apparatus having a base, a support platform and at
least two legs pivotally attached to the base and the support
platform. A longitudinally adjustable member is connected between
the base and the support member for infinitely adjusting and
securing a vertical position of the support platform above the base
between two end positions.
[0006] In another embodiment of the invention, the adjustable
member includes a first hollow tube having a second end pivotably
attached to the support platform and a first open end. A second
hollow tube has a first end pivotally attached to the base and a
second end arranged within the first tube via the first end of the
first tube. A mechanism is also provided for moving the tubes
relative to one another.
[0007] The moving mechanism, in one embodiment, includes a threaded
first shaft rotatably mounted in one of the tubes and a threaded
sleeve fixed in the other of the tubes. A threaded shaft is
arranged to pass through the sleeve so that rotation of the shaft
causes the sleeve to move along the shaft.
[0008] In still another embodiment, the first shaft is mounted in
the first tube and the threaded sleeve is fixed in the second tube.
In yet another embodiment, the moving mechanism further includes a
gear mechanism for rotating the threaded shaft from outside the
first tube. The gear mechanism includes a second shaft arranged
substantially perpendicular to the first shaft and extending
through a wall of the first tube. The second shaft has a first end
outside the first tube and a second end inside the first tube. A
first gear is mounted on the second end of the second shaft and is
in engagement with a second gear mounted on the first shaft.
[0009] In still another embodiment, the first and second gears are
bevel gears. Furthermore, a crank can be mounted on the first end
of the second shaft to facilitate rotation of the second shaft.
[0010] Another embodiment provides a stop mounted on the base so
that one of the legs rests against the stop in one of the end
positions.
[0011] In yet another embodiment, the second end of the first tube
is mounted to the support member in a region in which a first one
of the legs is attached to the support member and the first end of
the second tube is mounted to the base in a region in which a
second one of the legs is attached to the base.
[0012] Other features and advantages of the present invention will
become apparent from the following description of the invention
which refers to the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0013] FIG. 1 is a side view of the inventive exercise apparatus in
a first end position;
[0014] FIG. 2 is a side view of the inventive apparatus in a second
position; and
[0015] FIG. 3 is a cross-section showing the crank mechanism;
DETAILED DESCRIPTION OF THE INVENTION
[0016] Referring to the drawings, FIG. 1 shows the inventive
exercise apparatus having a bench 1 with a base 2 on which legs 3,
4 are pivotally mounted at one end. A platform 5 is pivotally
mounted at the other end of the legs 3, 4.
[0017] A longitudinally adjustable member 6 is connected between
the base 2 and the support member 5. A stop member 7 is mounted on
the base 2 so that the leg 3 rests against the stop 7 in the
lower-most position of the support member 5, as shown in FIG.
1.
[0018] The adjustable member 6 extends between a point in a region
of the end of the leg 3 attached to the base 2, to a region of the
support member 5 where the legs 4 are attached. The adjustable
member 6 has an adjustable length so that as the length increases
from the position shown in FIG. 1 the support member 5 is raised
vertically to a second end position. The height of the support 5
can be maintained at any desired position between the lower-most
and upper-most positions.
[0019] The adjustable member 6 is made up of a first tubular member
8 and a second tubular member 9 arranged to slide within the first
tubular member 8 in a telescoping manner. One end of the second
tubular member 9 is attached to the base 2 and one end of the first
tubular member 8 is attached to the bottom side of the support
member 5. The tubular members 8, 9 are connected together by a
screw-drive mechanism arranged within the tubes. The screw-drive
mechanism includes a threaded shaft 10 is rotatably held within the
first tubular member 8 by a bearing 11. A proximal end of the shaft
10 is fitted with a first beveled gear 12. A second beveled gear 13
engages the first beveled gear 12 and is driven by a crank 14 via a
shaft 15 that extends through a side wall of the first tubular
member 8.
[0020] A threaded sleeve 16 is fixed within the free end of the
second tubular member 9 that is arranged in the first tubular
member 8. The threaded shaft 10 is threaded into the sleeve 16 so
that rotation of the threaded shaft 10 causes the sleeve 16 to ride
up or down the threads of the shaft 10, depending upon the
direction of rotation of the shaft 10, so as to move the second
tubular member relative to the first tubular member and thereby
change the length of the adjustable member 6 and in turn raise or
lower the support member 5. This rotation of the shaft 10 is
carried out by turning the crank or handle 14. By stopping the
turning of the handle 14 the support can be held at any desired
height between the two end positions.
[0021] It will be understood by those skilled in the art that other
types of rotation transmission mechanisms can be used in place of
the beveled gears.
[0022] It is also understood that although the illustrated
embodiment has three legs supporting the support member 5 on the
base 2, this support can also be provided by, if desired, two legs
or more than three legs.
[0023] Additionally, the stop member 7 is not essential for
practicing the invention, but is desirable for providing additional
stability in the lower-most position of the support 5.
[0024] Although the present invention has been described in
relation to particular embodiments thereof, many other variations
and modifications and other uses will become apparent to those
skilled in the art. It is preferred, therefore, that the present
invention be limited not by the specific disclosure herein, but
only by the appended claims.
