Exercise Chair
An exercise apparatus in the form of a chair has a seat that is flexibly connected to a base such as with a helical spring that allows flexing in multiple directions. The chair has a base such as a plurality of legs so that it may be fixed with respect to a floor. The chair may include handlebars having handles positioned no higher than the height of the seat above the floor. A user may flex his or body so that the seat flexes with respect to the base and thereby exercise the user's core musculature.
The present invention relates generally to exercise and fitness equipment, and related methods and programs for using the equipment, and more particularly to exercise equipment for home or personal use such as abdominal or cardiovascular workout machines such as rowing machines, treadmills, abdominal trainers, sit up boards, or other similar systems.
II. BACKGROUND OF THE INVENTIONIn modern culture, it is highly desirable for a person to obtain and retain a trim and strong physique. Likewise, it is advantageous to a person's health to habitually perform cardiovascular exercise and to exercise the person's core muscles (meaning the abdominal and back muscles). To these ends, people are continuously looking for exercise equipment that is easy, safe, fun, and effective for engaging the core muscles. A person's core muscles are made up of a set of muscle groups that facilitate movement such as bending forward or sideways at the waist, leaning backwards, and returning to an upright position from a bent position.
Many of the exercise machines available are based on the traditional sit-up from a prone or near-prone position. Furthermore, many of the machines available restrict the user to movement in one or two directions, thus failing to engage the full set of abdominal muscles. There is a need for exercise equipment that allows for a user to exercise the core muscles in every relevant direction.
There are many machines in this field that use complicated systems of weight, cables, and/or pulleys. Such systems are often large and expensive, and thus unsuitable for home use. There is a need for small, inexpensive home equipment that is easy to use, robust, effective, and relatively inexpensive.
The present invention allows a user to effectively exercise his or her core muscles by using a seat attached to a base through a flexible means as described hereinbelow. The invention allows a user to exercise his or her core muscles in every direction. The seat takes up only a small area on the floor, is easy to use, and does not require expensive pulleys or weights. Therefore, it is appropriate for home ownership and use.
In one embodiment, a seat 100 is attached via fastening means such as screws or bolts to a seat mounting bracket 110. The seat mounting bracket 110 is attached to a flexible support structure such as a helical spring 120. Said bracket 110 may be attached to one end of the spring 120 through a weld or fastening means such as screws or other connectors. The other end of the flexible support structure 120 is attached to a central mounting plate 130 (which is shown in detail in
In a preferred embodiment, the seat 100 has a rectangular shape, as seen from directly above the chair, such that the seat is shorter in the direction perpendicular to chest of a seated user, and longer in the direction parallel to the seated user. Preferably, the length of the longer side of the seat 100 is about twice that of the shorter side. Additionally, the seat 100 may be curved such that the ends of the longer dimension of the seat are higher from the floor than is the middle of the seat. The rectangular and curved shape of the seat 100 facilitate the side to side rocking motion of the user. Furthermore, the corners of the seat 100 should be rounded to avoid scratching or injury. The seat 100 ideally should comprise or be padded such as with foam or cloth for user comfort. The seat of a preferred embodiment, as described here, can be seen in
In a preferred embodiment, each handle bar 150 is connected to a horizontal support bar 140 which is welded or otherwise fixed to the mounting plate 130. In one embodiment, the support bar is in a U-shape as shown in
The handle 160 can be a final portion of the handle bar, comprising a sufficient length of the bar so as to properly fit a hand of a user. The handle 160 may be formed by the final portion of the handle bar 150 bent at an angle from the rest of the handle bar such that the handle is parallel to the direction of the user's feet, that is, to the major axis of the seat 100. In an alternate embodiment, the handle 160 might be formed perpendicular to the direction of the user's feet, that is, to the minor axis of the seat 100. The handle 160 is preferably no higher than the seat itself, such that the users hand is lower than the seat 100 and several inches away from the seat. The handle 160 may comprise or be covered with a material such as foam, plastic, vinyl, cloth or a similar substance to increase the comfort and grip.
The base of the chair can be attached to the central mounting plate 130 directly through a weld or other fastening means. The base may comprise a number of legs 180, such as four, sufficient to provide a stable base. In a preferred embodiment, each leg 180 can be connected to leg support bars 170 that are directly welded to the central mounting plate 130 in a tubular telescoping manner, such that the height of the chair may be adjusted to suit the user. The legs 180 may also be designed for quick removal from the leg supports 170, as shown in
A feature of the invention is that the seat is flexible in each direction relative to the central mounting plate. Thus, when a user is seated on the chair in a preferred starting position, the seat 100 can be flexed in a direction toward or away from the user's feet, toward or away from the user's side, or any combination thereof. That is, as facing the user in the typical position (see
In a typical exercise routine, the user sits on the chair and repeatedly bends at the waist in order to engage the core muscles. The user can bend forward at the waist for a discrete number of repetitions, and then bend sideways to one side or the other for a number of repetitions. During these exercises, the user may or may not choose to hold onto the fixed handles of the machine. Gripping the handles increases the stability and balance of the exercise, but is not necessary in all cases. Alternatively, the user can raise and lower one or both knees while performing the waist bends, or as an isolated exercise.
The user can also perform the various repetitions to music, which facilitates the orderly rhythm of the exercise. Specifically, the movements can be performed as though the user were accomplishing a dance while seated.
