Abstract
This is a multiple function exercise device that enables simultaneous exercise of several muscle groups. The device includes a chest pad that is stationary to the support frame and a seat that moves in a path of motion that enables the user's chest to remain on the chest pad as the user's legs are extended, thereby causing movement of the seat. This combination provides activation of the leg and hip extensor muscles and the trunk flexor muscles at the same time. In another embodiment, a resistance arm is added that is pivotally attached to the frame and mechanically linked to the seat, thereby causing movement of the arm as the seat moves. This allows the additional activation of the triceps muscles, or elbow extensors of the upper arm, while also working the leg and hip extensor muscles and the trunk flexor muscles all in a single movement. The advantage to such a movement is the time saving effect of working a large group of muscles at one time as opposed to several exercises one after the other.
Description
BACKGROUND OF THE INVENTION
The invention herein relates to an exercise device and more particularly to exercise devices that allow for work done concurrently by multiple muscle groups. This multiple function capability has an advantage in the time saving effect of working a large group of muscles at one time as opposed to several exercises one after the other. The busy schedules of the users are of utmost importance in any physical activity to promote physical health. Few people will or can spend and hour or more in the gym each day. A minimal 30-minute cardiovascular workout followed by 30-40 minutes of weight training doesn't even allow for a quick bite on the way back to the office.
As more and more individuals work out of their homes, the need for fitness products that are usable in a home setting become more desirable. One of the necessities of a home piece of fitness equipment is in the versatility or variety of exercises that can be done given a specific space requirement of the device. A single device that performs a variety of exercises is very desirable in this respect. If the device also enables two or more exercises to be accomplished in a single composite movement, the device solves both the time and space considerations that would otherwise prevent many users from participating in a fitness program.
Most health club products are not as sensitive to space as in the home market. As such, traditional health club facilities greatly rely on single function equipment, that is a device that works a particular muscle group. Though health club facilities are obviously dedicated to equipment placement and usage, unlike a home, but the space allotment still has associated costs including building rent. Therefore it is advantageous in many cases to provide equipment that has multiple uses. Traditionally these are generalized devices such as jungle gyms, racks for free weights and linear motion smith machines. Still these are not intended to perform seemingly unrelated movements in unison to save time for the user.
SUMMARY OF THE INVENTION
Present Invention
In one aspect, the invention features a frame with a chest pad that is supported by the frame, and may be movably mounted to the frame and a seat that is movably supported on the frame. The seat is mounted such that when it moves relative to the frame, while supporting the pelvic region of a user, the path of motion of the seat enables the chest region of the user to maintain contact with the chest pad. The device may include a resistance arm, which is pivotally mounted to the frame and in mechanical communication with the seat.
The mechanical communication of the resistance arm may include a substantially rigid drive link with a first end pivotally mounted to the seat and a second end pivotally mounted to the resistance arm. An alternative form of mechanical communication includes a flexible tension member such as any of an item selected from the group consisting of a wire rope, a rubber belt, a Kevlar belt and a nylon rope.
The system may also include more than one form of mounting to the frame. The seat may be pivotally mounted to the frame. This may be done by use of two substantially rigid links each with one end pivotally mounted to the frame and each with a second end pivotally mounted to the seat. These links are likely pivotally mounted to the frame in such a way that there is not a common axis and also pivotally mounted to the seat without a common axis. The seat may also be slidably mounted to the frame.
The device may also include a foot support that is mounted on the frame, preferably moveably mounted. In the preferred embodiment the foot support is slidably mounted to the frame by use of a female tube that is mounted directly to the frame, which receives a male tube that is mounted directly to the foot support. This may also include a lock to releasably secure one to the other.
Additional resistance may also be applied to the user during exercise. This may be accomplished by use of one or more elastic bands or weight plates that are releasably secured to any moving element of the device.
In another aspects, the invention includes a method of providing an exercise device, which includes the detail as previously disclosed, positioning the pelvic region of the user in the seat and the chest region on the chest pad. The user then extends their legs while applying force to the chest pad, in combination, to move the seat. This concurrently exercises the extensor muscles of the lower body and the flexor muscles of the trunk of said user. This method can also be expanded where the exercise device further includes a resistance arm that is previously disclosed, and then further includes the step of extending the arms of the user, thereby also concurrently exercising the elbow extensor muscles of the user.
Definition of Terms
Unless otherwise defined, all technical and scientific terms used herein have the same intended meaning as would be commonly understood by anyone of ordinary skill in the art to which this invention belongs. To eliminate possible ambiguity, specific terms used herein have been defined, as they would be applied to the present invention.
An “elbow extensor” is any muscle serving to cause an increase in the joint angle of the elbow or extend the lower arm from the upper arm. This muscle group is also referred to as the triceps or triceps brachii which is the large muscle situated along the back of the upper arm.
A “hip extensor” is any muscle serving to cause an increase in joint angle of the hip as measured from the anterior aspect of the body within the sagittal (vertical longitudinal) plane. This muscle group is referred to as the gluteus muscles or in common form the buttocks.
A “leg extensor” is any muscle serving to increase the joint angle of the knee or ankle as measured from the anterior aspect of the body for the ankle and the posterior aspect of the body for the knee. Both are measured within the sagittal (vertical longitudinal) plane. The ankle extensors include the more superficial gastrocnemius muscle and soleus muscle positioned directly deep relative to the gastrocnemius. The knee extensors include quadriceps muscle which is a large muscle located on the anterior aspect of the thigh. This muscle is a generic term covering the vastus lateralis, vastus medialis, vastus intermedius and the rectus femoris.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The object of the disclosed invention is to provide an improved device and method for enabling exercise of multiple muscle groups in a single movement on a single machine. In this invention, the muscle groups include the elbow extensors, trunk flexors and the hip, knee and ankle extensors each individually or any combination thereof.
What is shown in
FIG. 1
is an isometric view of a multiple function exercise device
10
. An upper front side view shows a bottom seat
12
, a back seat
14
, which in combination, comprises the seat
16
of the device. The seat enables at least partial support of a user at the lower torso of the user. The seat
16
is supported by a pair of lower links
18
at the lower portion and a pair of upper links
20
at the top portion of the seat
16
. These upper links
20
and lower links
18
are pivotally mounted to the seat and the frame
22
of the device.
A chest pad
24
is positioned above the seat
16
and is so positioned to engage the chest of the user when the user is positioned on the seat
16
. The chest pad
24
remains stationary to the frame
22
while the device is in use. This offers a reactive force to the user when a force is applied by the user to the pad. When this force is applied to the pad
24
, by the chest of the user, the resultant action is a rearward movement of the seat
16
. The positioning of the links
18
&
20
mandate an upward movement of the seat
16
with this rearward movement. The upward component of the seat
16
and with it at least partial body weight of the user, results in work done by the abdominal muscles of the user.
A foot plate
26
is mounted to the frame
22
and can be done so in a variety of ways. In many applications it is desirable to movably mount the foot plate
26
. This is done here by use of a female tube
28
that is rigidly mounted to the frame
22
and a male tube
30
that is rigidly mounted to the foot plate
26
. The male tube
30
is received by the female tube
28
. This allows the foot plate
26
to move relative to the frame
22
while maintaining support due to the presence of the telescoping male
30
and female tubes
28
. A lock
32
such as a spring loaded pin, screw pin or any other locking device known in the art can be used to releasably secure the foot plate
26
in various positions relative to the frame
22
.
The foot plate
26
is used to provide resistance for the user to push against, thereby extending the legs of the user and moving the seat
16
in an upwardly and rearward motion. This motion is similar to that as previously described in that the seat
16
follows a predetermined path relative to the frame
22
. As previously noted, the upward movement of the seat
16
and associated body weight of the user, results in work done by the user. In this case the extensor muscles of the lower body are doing the work. It is also possible to exercise both the legs and the abdominal muscles by concurrently flexing the trunk as the user's chest is pressed against the pad
24
while the user's feet push against the foot plate
26
. Both movements causing vertical displacement of the seat
16
and therefore doing work.
A third aspect to the invention
10
is obtained by use of the handles
34
. The handles
34
are rigidly mounted to arms
36
, which are movably mounted, and in this case, pivotally mounted to the frame
22
at a pivot shaft
38
. Rotation of the handle
34
and resulting arm
36
causes movement of a push link
40
, which is pivotally mounted to the seat
16
at the rod
42
, which also supports the upper arm
20
. This common placement was accomplished by repeated iteration and analysis of the linkage combination and seat
16
movement. This common pivot design is desirable for manufacturing simplicity and aesthetic appreciation, but is not necessary for the function of the invention.
When the handles
34
are rotated about the pivot shaft
38
, down toward the seat
16
, the push link
40
causes rearward and therefore upward movement of the seat
16
. Again, this seat
16
movement is as previously described. The positioning of the handles
34
and the relative placement of the pivot shaft
38
enables the hands of the user to remain in contact with the handles
34
as the user is seated in the seat
16
. As such, the user can extend at the elbows while seated in the seat
16
. The vertical movement of the body weight of the user provides resistance to the elbow extensors, thus exercising those muscles.
As stated previously, the seat of the device moves relative to the frame in a similar manner regardless of the mode of displacement used; pressing against the chest pad
24
; pushing against the foot plate
26
; or pushing down on the handles
34
. The elbow extensor (triceps) muscles can be exercised alone by movement of the handles
34
. The leg extensor muscles or trunk flexor (abdominal) muscles can also be exercised alone or in combination by the movements as previously noted. The triceps can be exercised concurrently with the legs or the abdominals or all three can be exercised at the same time. The user decides by how much, if any, pressure is placed on each of the handles
34
, foot plate
26
and chest pad
24
, separately or in any combination. In doing so, the user's workout is infinitely variable and can conform to the amount of emphasis the user places of each exercise movement aspect of the device
10
.
To more explicitly detail the linkage of the preferred embodiment, a schematic of the linkage is shown in FIG.
2
. The handle
34
is connected to the arm
36
, which is pivotally mounted to the frame by pivot shaft
38
. An arm extension
43
provides a support for the push link
40
. The other end of the push link
40
and the one end of the upper link
20
are pivotally mounted to the upper portion of the seat
16
at the rod
42
. The lower link
18
also supports the seat
16
. Downward movement of the handle
34
and arm
36
results in an upward movement of the seat
16
, as illustrated by the elevated (top position) of the seat
16
.
More detail of the device
10
is shown in the top view in FIG.
3
and the side view in FIG.
4
. The general positioning of the device
10
can be seen in these views. The user's body fits between the handles
34
and attached arms
36
and is positioned on the seat
16
with the body in a traditional seated position. The user's chest is positioned against the chest pad
24
and hands upon the handles
34
. This constitutes the starting position of the device
10
.
Movement of the device
10
is illustrated in FIG.
5
. Here,
FIG. 5
a
shows the starting position, as has been depicted thus far in the previous figures. A middle position of the device
10
in use is shown in
FIG. 5
b
and a final or top position is shown in
FIG. 5
c
. A simulated body
44
is used to show how the device
10
would typically be used. Typically, when the device
10
reached a top position, as illustrated in
FIG. 5
c
, the user would reverse the direction of movement and descend back to the position of
FIG. 5
b
and then to
FIG. 5
a
. The process would then be repeated as desired by the user.
In the starting position,
FIG. 5
a
, the body
44
is positioned on the seat
16
with the chest against the chest pad
24
. The feet
45
of the body
44
are positioned against the foot plate
26
and the hands
48
on the handles
34
. Forces can then be applied by any, all or any combination of body parts of the user to actuate the seat
16
to a higher position as illustrated in
FIG. 5
b.
These forces applied by the body
44
are illustrated by force vectors F
F
as applied by the feet
45
against the foot plate
26
; F
C
as applied by the chest against the chest pad
24
and F
H
by the hands
48
against the handles
34
. A force applied by the feet (F
F
) results in an extension of the legs of the user to move the seat
16
and a portion of the weight of the user
44
from the starting position in
FIG. 5
a
to the middle position of
FIG. 5
b
and finally to the final position shown in
FIG. 5
c
with little change in the orientation of the force as the movement continues (F
F2
to F
F3
).
Like the foot plate
26
, while in use, the chest pad
24
remains stationary to the frame
22
of the device
10
. The force applied (F
C
) causes a substantially horizontal reaction force in the first position. This force (F
C2
) becomes more vertical in orientation in the middle position as the body is elevated and the trunk flexes. This direction change of the force (F
C3
) continues even more as the body
44
is further elevated to the top position. The pad
24
is intentionally round from the side view to accommodate slight misalignments of the body
44
with the machine caused by variations in trunk height and trunk flexibility of individual users. This is desirable, but not mandatory, in that the inventors have found that in application, the device yields a minimal change in position of chest contact of the body
44
relative to the pad
24
during the movement, regardless of user stature, age or sex.
It is important that the chest of the user is capable of maintaining contact with the pad
24
throughout the range of the movement. That can be accomplished in two ways, either the pad is able to articulate relative to the chest (pad rolls on chest) or for optimal comfort of the user, allow the pad
24
to move relative to the frame
22
(pad roll on machine). In normal use of the device
10
, and in ideal placement of the chest pad
24
relative to the body
44
, no translation of the chest of the body
44
relative to the pad
24
occurs, but the direction of the chest force vector (F
C
) changes as the body
44
moves. It has been determined most desirable to enable the chest pad
24
to rotate about an axis bar
46
. This allows the contact of the pad
24
with the chest of the user to remain constant as the pad
24
rotates about the axis bar
46
. The structure of the axis bar
46
provides the structural integrity to enable the reaction force associated with the forces applied by the chest against the pad
24
. This happens as the chest moves relative to the frame
22
, but not the pad
24
, even as the force vector changes in direction from F
C
to F
C2
to F
C3
.
As a user's strength increases it may become desirable to add resistance beyond the body weight of the user. This is illustrated in two ways.
FIG. 5
a
shows a weight plate
47
attached to the seat
16
. As the exercise movement is performed, the weight plate
47
is elevated by the upward movement of the seat
16
, as provided by the user.
FIG. 5
b
shows this elevated position of the weight plate
47
. In a similar fashion, an elastic band
49
can be mounted between any frame member of the device
10
and the seat
16
or any other moving part. This is illustrated in
FIG. 5
c.
As the seat
16
moves during the exercise, the elastic cord
49
is stretched. This increase in tension in either method results in increased work done by the user.
Any exercise device is only of value if the user is able to use it. The device
10
is shown in
FIG. 6
to show one method of entry into the device
10
. The chest pad
24
is supported on the axis bar
46
, which is movably mounted on the frame
22
. This is can be done in a variety of ways, in that the object is to allow the user to gain access to the seat
16
. In the preferred embodiment, the axis bar
46
is pivotally mounted to the frame
22
along an axis that is substantially vertical. In this way the bar
46
, and accompanying pad
24
can rotate away from the opposite side of the frame
22
, thereby opening a space for the user. To secure the bar
46
in place, a notch
50
is placed in the support mount
52
. This notch
50
is capable of receiving the end portion of the bar
46
, thereby releasably securing it to the frame
22
.
An upper rear view of the device
10
is shown in FIG.
7
. This shows more detail of the structure of the arms
36
in the preferred embodiment. The handles
34
attach to the arms
36
and are supported by the frame
22
at a bearing
53
. This bearing
53
rides on the pivot shaft
38
. The arms
36
have an upward stop in the upper brace
54
. This brace
54
has two functions. The most obvious is the upward stop of the arms
36
, thus preventing them from being pulled up excessively and potentially injuring the user or over centering the articulating push link
40
. The second function is the support of the support mount
52
. This enables the support mount
52
to be positioned inside of the arms
36
and yet supported by the frame
22
, which is generally on the outside of the arms
36
.
A modified version of the invention is shown in
FIG. 8. A
handle
34
is attached to an arm
36
, which as in the previous figures, is pivotally mounted to the frame
22
. The seat
16
is now supported on the frame
22
by wheels
56
that ride in a track
58
, the track being mounted to the frame
22
. Movement of the seat
16
along the track
58
is enabled by a cord
60
that is connected to the seat
16
and a cam
62
, which is in turn connected to the arm
36
. Thus, movement of the arm
36
results in movement of the cord
60
. The cord
60
is guided by a pulley
63
and directed along the track
58
to the seat
16
.
The angle (alpha) denotes the angle of the track
58
with respect to the horizontal. This angle is critical, within a range, in that if the angle is to great the vertical component will be to great and the user's chest will not maintain contact with the pad
24
during the movement of the seat
16
. If the angle is to low, a similar problem will ensue only in the opposite direction. An optimal angle was determined by the inventor to be 56.5 degrees. A preferable range has been determined to be between 51 and 62 degrees as denoted by the angle alpha.
Also in this figure, an alternative movement of the chest pad
24
is shown. This again is done to allow entrance to the seat
16
by the user. Here, instead of a pivotal mount on the side of the frame, a chest pad arm
64
is used to support the chest pad
24
and this arm
64
is pivotally mounted to the frame
22
behind the user's head
66
. This allows the chest pad
24
and the arm
64
to be raised over and back of the user, opening the space for the user to enter and exit the machine.
It is to be understood that a number of combinations are possible in regarding the lengths and positions of the linkages to enable seat
16
movement while maintaining chest contact with the pad
24
and providing constant contact of the user's hands with the handles
34
. The attached drawings are scaled versions depicting only two versions.
Additional load can be used on any version of the invention by adding additional weight plates to any moving part, especially the seat
16
. Another variation would be to use elastic cords that are anchored to the frame
22
. The cords can be anchored to resist vertical movement of the seat
16
or assist this movement. This can be accomplished in an infinite number of ways, including mounting a cord to the seat and anchoring it to the frame below or above the seat to add or subtract resistance, respectively or in the form of a torsion spring on any rotating joint.
In addition, the enclosed information is presented as the preferred embodiment as seen by the inventors. An infinite number of variations and modifications can be made including various forms of additional force (load) application, framework design and linkage arrangements. Both a pivoting and a linear tracking mechanism are disclosed and within each of those designs also exists an infinite number of design variations.
