Patent Application
20070129225
This invention relates generally to exercise machines for exercising a user's abdominal and back muscles. Exercise machines generally provide resistance to the movement of a user in order to strengthen muscles of the user's body. However, conventional techniques, such as sit-ups, crunches, or roman chair hyperextension exercises, use the body's own weight to exercise the abdominal and back muscles of the user. Consequently, the conventional techniques fail to provide support and controlled resistance to the movements of a user, which can be particularly problematic for out-of-shape or obese users. Specifically, conventional techniques lack ways to control the resistance and motion of the user to prevent injury from an uncontrolled movement or from overloaded and strained muscles.
Of the available exercise machines that may be used to exercise and strengthen a user's abdominal and back muscles by providing resistance to the user's movements, many only permit certain portions of the abdominal and back muscles to be exercised, which leaves other portions unexercised and typically uneven in strength. This often leads to injury. Furthermore, many of these machines do not support the user's back during the exercise, which may lead to hyperextension injuries. These exercise machines also may not be capable of adjusting the resistance to a user's movements or adjusting the position of the user to provide more difficult exercise routines. Additionally, many currently available exercise machines take up large amounts of usable space when not in use, which prevents them from being conveniently located in the user's residence.
Accordingly, a need exists for an exercise machine that permits the position of a user to be adjusted for more or less difficulty during an exercise routine. A need exists for an exercise machine that supports the back to prevent injury and uncontrolled movements. Additionally, a need exists for an exercise machine that offers the ability to change the resistance to the motion of the user in exercising their abdominal and back muscles. Furthermore, a need exists for an exercise machine that does not occupy an excessive amount of room when it is not in use and that permits easy and convenient storage.
The apparatus and system of the present invention has been developed in response to the present state of the art, and in particular, in response to the problems and needs in the art that have not been fully solved by currently available exercise machines. Thus, the present invention provides an exercise machine that supports and provides resistance to the movements of a user while performing abdominal, oblique, and back exercises.
An embodiment of an exercise apparatus for use on a base surface by a user is disclosed. The exercise apparatus includes a foldable frame for supporting a seat above the base surface. The foldable frame is moveable between an exercise mode and a storage mode. The exercise apparatus also includes a moveable backrest. The moveable backrest includes a resilient spine member.

The frame includes a front leg. The frame also includes a rear leg. The rear leg is pivotally attached to the front leg by a pin joint such that the rear leg extends from the front leg at an angle in the range of about 100 degrees to about 110 degrees. The rear leg also includes at least one attachment ring for connecting a resistance band to the exercise apparatus. The exercise apparatus also includes a moveable backrest. The moveable backrest includes a resilient spine member. The moveable backrest also includes a first end connected to the frame and a second end that is freely moveable. The moveable backrest may also include at least one elongate flexible member. Each elongate flexible member comprises flexible material to provide resistance to the movement of the user. The backrest is disposed to provide support to the user's back and neck during movement of the backrest. The exercise machine further includes a bracket that is pivotally connected to the backrest. The bracket includes at least one aperture. The bracket is attached to the rear leg using a pin through one of the apertures. The bracket is also used to adjust the position of the backrest connected to the rear leg. At least one of the apertures is configured to position the backrest in a substantially non-vertical position. The exercise apparatus also includes at least one pad. Each pad captures the resilient spine member and may capture the one or more elongate flexible members. One of the pads is attached to the bracket. The exercise machine further includes a handle that is disposed near the second end of the backrest.
In some embodiments, the second end of the backrest twists with respect to the first end of the backrest if acted upon by a threshold torsional force. In other embodiments, the second end of the backrest moves forward or backward with respect to the first end of the backrest if acted upon by a threshold, forward or backward, force. In further embodiments, the second end of the backrest moves side to side with respect to the first end of the backrest if acted upon by a threshold side to side force. In still further embodiments, the second end of the backrest moves forward and backward or side to side while twisting with respect to the first end of the backrest if acted upon by a threshold forward, backward, or side to side force and a threshold torsional force.
In some embodiments, the exercise apparatus further includes a bracket connected to the frame that includes at least one aperture. The bracket is used to adjust the position of the backrest with respect to the frame. In still further embodiments, at least one of the apertures is located to position the backrest in a substantially non-vertical position. In some embodiments, each of the apertures corresponds to a position that represents a desired difficulty such that the user can select a position and thereby select a desired difficulty. In further embodiments, one of the apertures is located to position the backrest in a substantially horizontal position (i.e., generally parallel to the base surface). In still further embodiments, one of the apertures is located to position the backrest in a position that is below horizontal (i.e., generally between the horizontal position and parallel to the rear leg).
In some embodiments, the exercise apparatus further includes one or more flexible members that may be disposed adjacent to the resilient spine member and captured by the backrest such that each added flexible member provides a different resistance to the user's movements than the resilient spine member alone. In further embodiments, the exercise apparatus also includes at least one pad, which captures the resilient spine member. In still further embodiments, the exercise apparatus further includes a handle that is disposed near the second end of the moveable backrest.
These and other features of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.
In order that the manner in which the above-recited and other features and advantages of the invention are obtained will be readily understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments of the invention and are not therefore to be considered to be limiting of its scope, the invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
The presently preferred embodiments of the present invention will be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout. It will be readily understood that the components of the present invention, as generally described and illustrated in the figures herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the exercise machine of the present invention, as represented in
The phrases “connected to,” “coupled to,” and “in communication with” refer to any form of interaction, though not necessarily direct interaction, between two or more entities, including mechanical, electrical, magnetic, electromagnetic, and thermal interaction. For example, a part or piece may intervene between two pieces that are “connected to,” “coupled to,” and “in communication with” each other. The phrase “attached to” refers to a form of mechanical coupling that restricts relative translation or rotation between the attached objects. The phrases “pivotally attached to” and “slidably attached to” refer to forms of mechanical coupling that permit relative rotation or relative translation, respectively, while restricting other relative motion. The phrase “directly attached to” refers to a form of attachment by which the attached items are either in direct contact, or are only separated by a single fastener, adhesive, or other attachment mechanism. The term “abutting” refers to items that are in direct physical contact with each other, although the items may not be attached together.
In the exercise position, the front leg 102 may extend from the rear leg 104 at angle 114. The angle 114 may range from about 90 degrees to about 130 degrees. However, the exercise apparatus 100 may still operate at angles 114 outside these stated ranges. In the present embodiment, the front leg 102 extends from the rear leg 104 at an angle 114 in the range of about 100 degrees to about 110 degrees.
As shown, the front leg 102 and the rear leg 104 may each be attached to feet 116a, 116b. The feet 116a, 116b may extend on both sides of the exercise apparatus 100 to stabilize and provide a sturdy base for the exercise apparatus 100. The rear foot 116b, in the present embodiment, is attached to the rear leg 104 and includes attachment rings 118 for connecting resistance bands (shown in
The resistance bands may be used with the exercise apparatus 100 to strengthen the arms, chest, and shoulders. For example, the resistance bands may permit a user to perform exercises such as Bench Press, Military Press, Chest Fly, Bicep Curl, Lateral Fly, Front Raise, Shoulder Press, and other exercises.
In the present embodiment, the seat 106 is connected to and extends from the rear leg 104. In other embodiments, the seat 106 may be connected to another portion of the exercise apparatus 100, such as the front leg 102, the bracket 120, etc. The seat may be padded for added comfort and may include a non-slip material to prevent a user from slipping off of the exercise apparatus 100 while exercising.
The backrest 108 may be pivotally attached to the rear leg 104 by a bracket 120. Specifically, in the present embodiment, the bracket 120 is pivotally coupled to the rear leg 104 by a bolt 122 and the backrest 108 is attached to the bracket 120.
The bracket 120 may include at least one aperture 124, 126, 128, 130. In the present embodiment, the bracket 120 includes a first aperture 124, a second aperture 126, a third aperture 128, and a fourth aperture 130 that may be used to position the backrest 108. Thus, as the bracket 120 is adjusted and secured to different positions, the backrest 108 may also be adjusted to a plurality of use positions to provide varying levels of difficulty in exercising the core muscle groups.
A pin 132 may be positioned to extend through the desired aperture 124, 126, 128, 130 and a hole (shown in
To prevent the backrest 108 from being pivoted too far forward, the bracket 120 may include a stop pin 134 that is inserted through a stop pin aperture 135. When the backrest 108 is moved to its forward-most position, the stop pin 134 may abut a bottom surface 119 of the rear leg 104. The stop pin 134 may be welded into place or may be fastened in position.
The exercise apparatus 100 may include a resilient spine member 138. The resilient spine member 138 may support the user's back and will be discussed in more detail in
The resilient spine member 138 may include a first end 140a and a second end 140b. The first end 140a may be connected to the frame 101 by fasteners, welding, or any other connection method. In the present embodiment, the first end 140a is connected using fasteners (not shown) to the bracket 120. The bracket 120 may be connected to the rear leg 104 of the frame 101. In some embodiments, the first end 140a may be directly connected to the frame 101, rather than indirectly connected to the frame 101 through the bracket 120, as in the present embodiment, or may use some other type of indirect connection. The second end 140b of the resilient spine member 138 is freely movable in any direction except toward the first end 140a.
The series of pads 142 may be made of plastic, composite material, metal, foamed plastic, or any other suitable material. The series of pads 142 may be connected to or disposed over the resilient spine member 138. In the present embodiment, only the bottommost and topmost pads 142 are connected to the resilient spine member 138, while the remaining pads 142 are slidably attached to the resilient spine member 138. For example, one of the pads 142 may also be attached to the bracket 120 to prevent the bracket 120 from abutting and irritating the back of a user. Attaching one of the pads 142 to the bracket 120 may also help to isolate certain muscle groups during an exercise routine. The pad 142 may be attached to the bracket 120 by fasteners (not shown).
Spacers 144 may be included with the series of pads 142. The spacers 144 may be used to attach the pads 142 to the resilient spine member 138 and to separate the series of pads 142. The spacers 144, in the present embodiment, are connected to a structural portion (not shown) of the pads 142. Cushioned portions 146 may be disposed to provide a comfortable surface to engage a user's back.
The seat 106 may be connected to the frame 101. In the present embodiment, the seat 106 is bolted to the frame 101. The seat 106 may be integrally formed with, welded to, or otherwise connected to the frame 101 using any connecting method.
To adjust the resistance of the forces 141a, 141b, 141c created by the user's movement of the backrest 108, one or more additional flexible members 136 may be added or removed from the backrest 108. The flexible members 136 may provide support to the user's back and may provide resistance to forward and backward forces 141a, side to side forces 141b, and torsional forces 141c in order to strengthen the user's the abdominal, lower back, and upper back muscles.
The flexible members 136 may be elongated members made of a resilient material and/or may have a resilient structure. For example, the flexible member 136 may be made of nylon, fiberglass, plastics, metal, and/or composite materials and may be shaped as a rod, beam, leaf spring, or coiled spring. By varying the materials and/or design of the flexible member 136 the backrest 108 may provide different levels of resistance to the movements of a user.
In the present embodiment, the flexible members 136 have generally the same resistance characteristics. For example, the flexible members 136 may include a circular profile in order to provide relatively uniform resistance to any direction a force may be applied to the backrest 108. Of course, other profiles may be used in order to increase resistance in desired directions. Alternatively, the flexible members 136 that are used may have different resistance characteristics.
The flexible members 136 may extend through loops 158 of the spacers 144 of the pads 142 and may be attached to an attachment structure 148 by the pin 154 and secured by the cotter pin 156. The flexible members 136 may be secured to the backrest 108 in any fashion and may or may not be removable. In the present embodiment, the flexible members 136 may extend into a pocket 160 of the bracket 120. Specifically, the proximal end (not shown) of the flexible member 136 is secured within the pocket 160 by fasteners (not shown).
Though, in the present embodiment, two flexible members 136 are used, in other embodiments, only one flexible member 136 may be used. In further embodiments, more than two flexible members 136 may be used. In many embodiments, the user may select the number and resistance characteristics of the flexible members 136 used to customize the user's exercise routine.
The series of pads 142 may include the attachment structure 148 for attaching the pads 142 to the first end 140a of the resilient spine member 138 and to the handles 152 of the backrest 108. The structural portions 145 may be molded over the attachment structure 148 to securely integrate the attachment structure 148 with the pads 142. The structural portions 145 may or may not be connected to the spacers 144.
The handles 152 may be connected to the attachment structure 148 by fasteners, may be welded into position, or may be connected using any other connection method. In the present embodiment, the handles 152 are connected to the attachment structure 148 using fasteners (not shown).
At this first exercise position, the angle A may range from about 105 degrees to about 125 degrees from the vertical axis 182, such that the backrest 108 is in a position below horizontal with respect to the support surface 110. In the present embodiment, the angle A is about 115 degrees from the vertical axis 182, such that the backrest 108 is in a position about 25 degrees below horizontal.
The backrest 108 also extends at an angle B to seat 106. The angle B between the seat 106 and the backrest 108 may range between about 180 degrees to about 200 degrees. In the present embodiment, the angle B between the seat 106 and the backrest 108 is about 190 degrees.
The backrest 108 also extends at an angle D to seat 106. The angle D between the seat 106 and the backrest 108 may range between about 150 degrees to about 180 degrees. In the present embodiment, the angle D between the seat 106 and the backrest 108 is about 165 degrees.
The backrest 108 also extends at an angle F to seat 106. The angle F between the seat 106 and the backrest 108 may range between about 120 degrees to about 150 degrees. In the present embodiment, the angle F between the seat 106 and the backrest 108 is about 135 degrees.
The backrest 108 also extends at an angle H to seat 106. The angle H between the seat 106 and the backrest 108 may range between about 90 degrees to about 120 degrees. In the present embodiment, the angle H between the seat 106 and the backrest 108 is about 105 degrees.
Of course, the exercise apparatus 100 may be modified to provide for additional exercise positions that correspond to additional fixed positions between the backrest 108 and the bracket 120. These additional exercise positions should dispose the backrest 108 at an angle ranging from about 20 degrees from the vertical axis 182 toward the seat 106 to about 135 degrees from the vertical axis 182 away from the seat 106. The apertures 124, 126, 128, 130 may be replaced with a slot (not shown). The slot may enable the user to lock the backrest 108 in multiple positions within the slot. For example, the pin 132 may be replaced with a fastener that may clamp the bracket 120 to the frame 101.
As shown, the front leg 102 and the rear leg 104 are generally straight beams in order to minimize the profile of the exercise apparatus 100 in the non-use, storage mode. Of course, the front leg 102 and the rear leg 104 may also be curved to be more aesthetically pleasing, though the exercise apparatus 100 may utilize more room when in its non-use, storage mode.
This non-use, storage mode permits the exercise apparatus 100 to be easily stored in a closet or under or behind furniture, such as a bed, couch, or dresser when the exercise apparatus 100 is not in use. This non-use, storage mode is especially advantageous in small apartments and condos where space is limited. In the present embodiment, the exercise apparatus 100 may be hung from a wall using the rear foot 116b.
In summary, an exercise machine for strengthening the abdominal and back muscles of a user includes a backrest for supporting a user's back to prevent injury. The backrest includes flexible members for adjusting the resistance the backrest provides to the user's movements. The backrest is also adjustable in position to control the difficulty of an exercise routine as well as the stress and strain that a user's back and abdominal muscles are subjected to during an exercise routine. The exercise also includes a non-use, storage mode that facilitates storage and makes the exercise machine more accessible because it may be kept at home or in an office where the user is most likely to use the exercise machine.
The present invention may be embodied in other specific forms without departing from its structures, methods, or other essential characteristics as broadly described herein and claimed hereinafter. The described embodiments are to be considered in all respects only as illustrative, and not restrictive. The scope of the invention is, therefore, indicated by the appended claims, rather than by the foregoing description. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
This application is related to and claims priority from Provisional U.S. Patent Application Ser. No. 60/737,437 filed Nov. 16, 2005, for an Adjustable Abdominal Exercise Machine, with inventor Rodney Hammer, which is incorporated herein by reference.
