Exercise device and system
An exercise device comprising an elongate, substantially upright and substantially rigid weight-bearing portion which includes a gripping portion extending across the top of the device, the weight bearing portion having an open bottom and generally lying in a first plane; a pair of feet, one at either end of the weight-bearing portion, extending outwardly to stabilize the upright weight-bearing portion without interfering with the open bottom, the feet being spaced apart to permit the positioning of a user between the feet and be clear of interference from the feet. The feet and weight-bearing portion are configured so that the mass of the device is generally balanced about said first plan.
This invention relates to the field of physical fitness, and in particular, the field of exercise devices for physical fitness.
BACKGROUND OF THE INVENTIONIt has long been recognized that regular exercise lengthens life and improves health. Historically, health and physical fitness professionals emphasized cardiovascular exercise, believing that such exercise would, by itself, provide a full range of health benefits. However, it has now been found that strength training is also an important component of any comprehensive fitness program.
For many people who would like to exercise regularly, one of the biggest problems is finding adequate time to do so. The demands of work, family and social interaction often leave little time for exercising. For this reason, many people attend regularly scheduled fitness classes several times per week in an attempt to meet their exercise needs. Historically, such fitness classes were directed primarily toward cardiovascular fitness, with some attention paid to flexibility as well. However, with strength now being recognized as an important component of fitness, fitness classes need to be adapted to provide strength training.
A common method of strength training is the use of free weights and/or weight machines. However, this method is not well-suited for fitness classes which usually consist of a group of people spaced apart in a large room following the instructor's workout routine. It would be impractical to provide an adequate selection of weights to each person in such a setting.
Without a variety of weights available to each class participant, one possible approach is to concentrate for strength training on exercises that involve only unassisted movement of one's own bodyweight. These include, for example, sit-ups and leg lifts. However, it has been found that such exercises alone do not provide adequate strength training.
There have been attempts to provide convenient and useful devices which allow the performance of a wider variety of strength training exercises. For example, U.S. Pat. No. 3,540,724 (“Hunter”) discloses an exercising device. The device comprises seven different pieces which can be attached to one another in different ways to create a variety of different configurations. Each configuration provides the user with the ability to perform different exercises, some of which are directed to strength training. However, the Hunter device is too complex for use in fitness classes. In a fitness class, there is no time for the participants to take apart a device and reconfigure it into a new complex configuration every time it is desired to perform a new exercise.
U.S. Pat. No. 4,258,915 (“Sellge”) discloses a self-locking ballet barre to allow ballet exercises to be performed. The barre has a horizontal section that deforms substantially when force is applied to it, and uprights that are angled away from the horizontal. This configuration is stated to improve stability. However, the Sellge device is directed to ballet exercises rather than general strength training. Furthermore, the elements of the Sellge device, being thin and elastic, are not well-suited to exercises which put more stress and pressure on the device, and in which more of the user's weight needs to be carried by the device.
U.S. Pat. No. 5,662,556 (“Gangloff”) discloses a portable exercise bar device. The device is foldable. The device has a base extending through the space between two uprights, and a bar spaced from the base and extending between the two uprights. The Gangloff device is limited to use as a chin-up bar. Also, though intended for use as a chin-up bar, the base of the Gangloff device inconveniently interferes with the user's body during the performance of chin-ups.
U.S. Pat. No. 5,169,362 (“Schwartz”) discloses a device for use in a strength-aerobic exercise method. The device is a complex structure including a base, a U-shaped bar having an upper crossbar, a transverse bar closing off the bottom of the U-shaped bar and two handled horizontal bars extending outward from the U-shaped bar. The purpose of the device is to permit the user to do certain specific exercises, such as scissor-kicking, high-knee kicking and “rhythmic bipedal movements.” This device is complex to manufacture, and has elements extending in various directions that could physically interfere with the performance of more conventional strength exercises.
SUMMARY OF THE INVENTIONTherefore, what is desired is an exercise system and device which is usable for a variety of strength training exercises, and preferably adapted for easy use in a fitness class environment, as well as personal training and home use. Preferably, the device will be configured to be suitable for use in performing exercises such as, for example, pull-ups and bicep curls. Also, preferably, the system will be adjustable so as to facilitate performance of exercises such as dips and pushups.

BRIEF DESCRIPTION OF THE DRAWINGSTo facilitate a better understanding of .the invention, a preferred embodiment will now be described with reference to the drawings, in which:
Referring now to
In the preferred embodiment, the weight bearing portion 12 is comprised of elongate hollow metal tubing, with the metal tubing preferably comprising 1.5 inch diameter, 16-gauge tubing. The metal tubing is preferably comprised of steel. This configuration for the hollow metal tubing is preferred for a number of reasons. First, hollow steel tubing is relatively inexpensive, and its use for the weight bearing portion 12 allows the device to be manufactured at a reasonable cost. Second, the purpose of the portion 12 is to bear the user's weight, and the use of steel, and 16-gauge steel tubing in particular, makes the portion 12 strong enough to support or bear the weight of users. Third, it is preferred that the device 10 be usable for weight-lifting exercises such as bicep curls. It has been found that when the portion 12 is composed of 16-gauge 1.5 inch hollow steel tubing, the device 10 is light enough to be used for most weight lifting exercises while being heavy enough to provide a strength training benefit. Fourth, the gripping portion is preferably configured to be easily and comfortably gripped. It has been found 1.5 inch diameter tubing is small enough to permit a comfortable grip.
Preferably, the weight bearing portion 12, and in particular, the gripping portion 14, is substantially round in cross section, as shown in
While this form of weight bearing portion 12 is preferred, it will be appreciated that other forms of weight-bearing portion are comprehended by the invention. What is important is that the weight-bearing portion be adapted to bear the weight of a user, and that it include a gripping portion 14 for the weight-bearing portion 12 to be gripped.
The weight bearing portion 12 is preferably configured so as to be substantially upright when the device 10 is in its standing position. Also, preferably, the weight bearing portion 12 generally lies in a plane, i.e. in the preferred embodiment, the generally upstanding sections 18 and transverse section 20 preferably lie generally in a single plane. In the preferred embodiment, the feet 16 extend outwardly from the plane to stabilize the upright weight bearing portion 12, most preferably at an angle of 90° to the plane.
Also, the feet 16 and weight bearing portion 12 are preferably configured so that the mass of the device 10 is generally balanced about the plane. This is preferred for two reasons. First, the device 10 is preferably used for weight-lifting exercises, such as bicep curls, which involve gripping the gripping portion 14 and lifting the device 10 off of the floor. In configurations where the mass of the device 10 is not balanced about the plane, the orientation of the device 10 will tend to shift suddenly when the device 10 is lifted, in response to the force of gravity and the eccentric centre of mass of the device 10. This sudden shift makes the lifting of the device less comfortable for the user and may place undue strain on the wrist or hand of the user. By contrast, this sudden shift upon lifting is reduced or eliminated when the mass of the device 10 is generally balanced about the plane. The preferred device 10 is thus configured to facilitate stable lifting of the device 10 without a sudden shift in the position of the device 10. The resulting strain on the user's wrists and hands is thus reduced or eliminated.
Second, as will be discussed further below, the device 10, alone or as part of the system 9, is preferably usable for exercises that require the device 10 to remain in a standing position on the floor while bearing the user's weight. These exercises include, for example, dips, push-ups and pull-ups. For a user to perform these exercises properly using the preferred device 10, the device 10 must be stabilized adequately so as to remain standing even when bearing the user's weight. With some exercises, such as push-ups, the user will typically apply a force to the weight-bearing portion 12, which force has a horizontal vector component. This horizontal vector component urges the device 10 out of its standing position and must be counteracted in part by the feet 16 which extend outward from the plane. When the mass is unbalanced about the plane, the device 10 will be more likely to topple if the horizontal force is applied from the “lighter” side of the plane than from the “heavier” side. When the mass of the device 10 is balanced about the plane, the device is equally resistant to toppling, regardless of which side of the plane the horizontal force is applied from. The balanced configuration is thus preferred because the user may position himself on either side of the plane while performing exercises without affecting the stability of the device 10.
As shown in
It will be appreciated that one of the preferred functions for the device 10 is its use for performing pull-ups. To perform the pull-ups, the user would preferably position himself between the feet 16, so that he is lying between the feet 16. The feet 16 are spaced apart so that the user can be positioned between the feet 16 and grip the gripping portion 14 clear of interference from the feet 16. The user's upper body is typically positioned under the portion 12 and between the feet 16, with the user's torso and legs extending outward along the floor in a direction generally perpendicular to the plane. To perform the pull-up exercise, the user then reaches up with his arms, grips the gripping portion 14, and pulls his bodyweight upward by pulling the portion 14, so that the weight bearing portion 12 supports the weight of the user. The weight-bearing portion 12 has an open bottom 22, meaning that the portion 12, feet 16 and device 10 are configured so that there is no obstruction between the feet 16, or between the floor and the portion 12, that interferes with the positioning of the user below the weight-bearing portion 12, or that interferes with the user pulling his body off of the floor to perform a pull-up. Because the weight bearing portion- 12 has an open bottom 22, a user can position himself under the weight bearing portion 12 as just described, and perform pull-ups as just described, without interference from the device 10.
This preferred configuration is in contrast to configurations in which the device interferes between the feet 16, or in the space between the weight-bearing portion 12 and the floor, or in the space, between the feet 16 and extending outward from the plane, where the user's body is positioned for pull-ups. In the preferred open bottom configuration, the user can position himself for pull-ups, with his body extending from the plane in either direction, without interference.
Another aspect of the invention is shown in
As the devices 10 are independently positionable, a user can adjust the distance and angle between the first and second exercise devices 10, so that the user can perform exercises which require the user to grip the gripping portion 14 of each of the two devices 10 and support some or all of his weight on both weight bearing portions 12 simultaneously. Meanwhile, the ground engaging feet 16 of each device 10 are configured to independently stabilize each weight bearing portion 12 while exercises are being performed using the system 9.
Those skilled in the art will appreciate that dips are typically performed with the user's arms supporting the user's entire weight during the exercise. However, the height of the gripping portion 14 is preferably selected so that the user is able to place his feet on the floor during the dip exercise if desired. If the user does not wish to do so, he can bend his knees to keep his feet off of the floor.
Having the gripping portion at this selected height has two results. First, a user unable to perform typical dips can still work the same muscles by performing the dip exercise while supporting his weight with his feet. Second, a user who can perform typical dips can do so until the relevant muscles have fully fatigued. Then, he can support a small portion of his weight with his feet and resume the dip exercise until the muscles are fully fatigued. The user can then support more of his weight with his feet and perform the exercise until the muscles are fully fatigued. The user then continues progressively reducing the load on the muscles for each set. Thus, the gripping portion 14 is positioned to permit the user to perform multiple sets of dips at variable or dropping resistance, which more fully fatigues the relevant muscles and provides a more thorough workout to those muscles.
It will be appreciated that this exercise is facilitated in part by the independently positionable nature of the two devices 10. Specifically, the user is able to perform this exercise by positioning the devices 10 roughly in a V-shape. Thus, at the point where the user grips the gripping portion 14, the gripping portions 14 are sufficiently close to allow the user to grip one in each hand. However, at the open end of the V-shape, the ends of the devices 10 are spread further apart, giving the user's body space to extend outward.
By contrast, to perform a dip exercise as shown in
In addition, it will be appreciated that the devices 10 are independently positionable so as to allow the distance between the devices 10 to be adjusted. For example, in performing the dip exercise shown in
It will be appreciated that the independent positionability of the devices 10 facilitates the comfortable completion of the pushup exercise. For example, as shown in
In addition, it will be appreciated that the performance of individual exercises can be adjusted to work different muscle groups to different degrees. For example, in performing pushups, the hands can be positioned further apart or closer together depending on which muscles the user prefers to work. If the user's hands are closer together, the triceps are worked harder. If the hands are further apart during the pushup exercise, then the pectoralis major and minor muscles, as well as the anterior deltoid muscle, are worked more. Thus, the system 9 and devices 10, by being independently positionable, are configured to permit biomechanical adaptation by the user, so he can work muscles of his choice. This increases the flexibility of the system 9 for the user.
The height of the gripping portion 14 from the floor is preferably selected to permit the user to perform multiple sets of push-ups at variable or dropping resistance, thus more thoroughly working the relevant muscles. To do this, the user progressively increases for each set the acute angle between his body and the floor, thus progressively decreasing the load for each set.
It will be appreciated that the device 10 will preferably have an open bottom 22, and the feet 16 are preferably spaced apart sufficiently to permit the user to be positioned between the feet 16 in the open bottom 22. In performing the tricep extension, the user extends his arms upward, and as he does so, the feet 16 of the device 10 naturally move to opposite sides of the user's body, so that the user is positioned in the open bottom 22 of the weight bearing portion 12. If the weight bearing portion 12 had a closed bottom, or if the feet 16 were not sufficiently spread apart to permit the user to be positioned between them, the device 10 would strike the user as he performed the exercise, thus interfering with comfortable completion of the exercise.
It will be appreciated that the device 10, and system 9, are preferably configured so as to permit the execution of a substantial variety of exercises. These include, for example, exercises such as pull-ups, push-ups and dips. Thus, it is preferred that the weight bearing portion 12 be substantially rigid, i.e. that the weight bearing portion not yield sufficiently to be perceptible to the user when the user uses the device 10 for exercises as pushups, pull-ups and dips. Performing these exercises in the most preferred way requires that the weight of the user be borne in a stable manner by the weight bearing portion 12. If the weight bearing portion 12 yields perceptibly in response to the user's weight, then the user may lose his grip on the gripping portion 14, or sprain or otherwise injure his wrists in trying to maintain his grip. Even if such drastic consequences do not occur, the device 10 will feel less stable to the user. By contrast, if the weight bearing portion 12 is substantially rigid as preferred, then the user will feel more confident and stable in using the device 10, and will be less prone to injury.
Preferably, both the feet 16 and weight bearing portion 12 are configured such that the height of the gripping portion 14 is fixed and the distance between the feet 16 is fixed. This structure is preferred because it is simpler and less expensive to manufacture. A device 10 having adjustable height and width would require multiple pieces which fit together with one another in a complex manner. It will be appreciated, however, that an adjustable structure, though not preferred, is still comprehended by the invention.
It will further be appreciated that the height and width of the device 10 are preferably selected so as to permit the comfortable and easy execution of exercises such as push-ups, pull-ups and dips using the device 10 and the system 9. For example, the space between the generally upstanding sections 18 and/or between the feet 16 is preferably selected so that a typical user can position himself between the feet 16 and perform a pull up exercise as shown in
It has been found that the distance D1 between the outer edges of upstanding sections 18 and between the feet 16 should preferably be more than about 16 inches and less than about 40 inches. Most preferably, the distance between the upstanding sections 18 and between the feet 16 will be about 25 inches. The distance D2 between the inner portions of the sections 18 is preferably between about 13 inches and about 37 inches, and most preferably about 22 inches and about 37 inches, and most preferably about 22 inches. These dimensions have been found to facilitate the performance of pull-ups by permitting a user to position himself between the feet 16, while keeping the device 10 small enough to allow it to be easily manipulated and moved around in a fitness class setting for use with various exercises. This width has also been found to provide sufficient stability so that the device generally will not topple during regular use by rotating within the plane.
Similarly, it has been found that the transverse section 20 and generally upstanding sections 18 should preferably be sized, shaped and positioned so that the top of the gripping portion 14 is positioned at a height H2 of between about 15 and about 42 inches above the floor when the device 10 is in a standing position. It has been found that, most preferably, the height of the gripping portion will be about 27 inches above the floor. Preferably, the lower end of the gripping portion 14 is positioned at a height H2 of between about 13.5 inches and about 40.5 inches above the floor. Most preferably, the height H2 is about 25.5 inches. These dimensions have been found to facilitate the performance of pull-ups by permitting a user to reach up from his position on the floor between the feet 16 and grip the gripping portion 14 as shown in
It will be appreciated that the preferred device 10 and system 9 should be usable for exercises that require the repeated movement of the device 10. Examples of such exercises are bicep curls, tricep extensions and side lateral raises. Preferably the device 10 will be light enough for a user to lift safely and comfortably, while being heavy enough to provide a strength training benefit when lifted. It has been found that the weight of the device should preferably be between 5 pounds and 15, and most preferably about 8 pounds. Thus, the portion 12, feet 16 and caps 24 (described below) are preferably configured so that the device 10 weighs between five and fifteen pounds, and are most preferably configured so that the device 10 weighs about eight pounds.
Preferably, each foot 16 has at least one anti-slide device associated therewith, and positioned to inhibit the sliding of the device along the floor when the device is in use and in a standing position. Most preferably, each foot 16 comprises an elongate element having two ends, and the anti-slide device comprises two anti-slide elements, one positioned at each end of the foot 16. Most preferably, the anti-slide elements take the form of rubber caps 24 positioned over the each end of each foot 16. This configuration is preferred because the caps 24 are effective yet simple and inexpensive to manufacture. However, other, less preferred configurations for the anti-slide elements are comprehended by the invention. For example, threaded anti-slide pads 26 are shown in
It will be appreciated that the preferred structure of the device 10, and in particular, the size, shape and position of the feet 16 and weight bearing portion 12, permit the devices 10 to be stored in a nested configuration, as shown in
It will be appreciated that it is preferred for the device 10 to be configured so as to be capable of being stored in a nested configuration. The devices 10 may be used in fitness classes. As such, for any particular class, many devices 10 may be required, depending on the number of participants. Thus, it is preferred if the amount of storage space required for the devices 10 is minimized. The ability for the devices 10 to be stored in a nested configuration reduces the amount of storage needed for the devices 10 as compared with the amount that would be needed if a nested storage configuration were not available.
Preferably, as shown in
The weights 30 may be of different weight levels, such as 1 pound, two pounds, 5 pounds or 10 pounds. Preferably, the device 10 comprises an even number of weights 30 so that the extra weight added by the weights 30 is distributed evenly on opposite sides of the portion 12. The even distribution of weight makes exercises such as bicep curls and tricep extensions easier and more comfortable to perform.
While the foregoing embodiments of the present invention have been set forth in considerable detail for the purpose of making a complete disclosure of the invention, it will be apparent to those skilled in the art that various modifications can be made to the device without departing from the broad scope of the invention as defined in the attached claims. Some of these variations are discussed above and others will be apparent to those skilled in the art. For example, the weight-bearing portion 12 may be made of plastic rather than metal, or may be made of a metal other than steel, or may be made out of some other material, and need not be hollow. What is considered important in the present invention is to provide an exercise system and device for use in strength training exercises, which device and system are practical for fitness class use, as well as personal training and home use.
