Description

    RELATED APPLICATIONS
  • [0001]
    The present application is related to U.S. Provisional App. No. 60/599,190 filed on Aug. 4, 2004.
  • FIELD OF INVENTION
  • [0002]
    The present invention generally relates to a combination lumbar support and exercise device. More particularly, the present invention relates to a lightweight and portable exercise device that provides both lumbar support and resistance for exercising a user's back muscles and abdominal muscles.
  • BACKGROUND OF THE INVENTION
  • [0003]
    Traditional lumbar support devices are limited in their versatility. Many are pillow-like devices which are placed between an individual's lower back and the seat back of a chair. Such devices only offer static lumbar support. They do not allow the user to move or flex the lower back against any device-provided resistance and do not permit the user to vary the amount of support or resistance provided by the device.
  • [0004]
    Traditional back and abdominal exercise devices are also limited in their versatility. For example, an individual cannot use most such devices while he or she is seated in an ordinary chair. Instead, such devices often require that the user use the device while lying prone on the floor, or the like. Many of these devices are rather large and cumbersome and are difficult to transport and store.
  • [0005]
    The traditional manner of performing “sit-ups”, wherein the exerciser lies on the floor on his or her back and lifts the torso toward the bent knees is generally adequate for exercising one's lower back and abdominal muscles. However, such exercises cannot be performed in some settings, such as in an office or while traveling on a train or airplane.
  • [0006]
    Accordingly, there is a continuing need for a device that provides lumbar support and enables the user to exercise his or her lower back and abdominal muscles. It is desirable to have a device that provides variable resistance such that the user can control and adjust the amount of lumbar support provided by the device and can control the amount of resistance provided in exercising the lower back and abdominal muscles.
  • SUMMARY OF PREFERRED EMBODIMENTS
  • [0007]
    The present invention is directed to a device that provides lumbar support and enables the user to exercise his or her lower back and abdominal muscles. In a preferred embodiment, the exercise device includes a self-inflating pillow having a compressed state and an expanded state. In an initial position, the pillow is biased in an expanded state. To perform exercises, the user must compress the pillow by applying force on the pillow. A two-way valve is provided on the pillow to facilitate the intake and the exhaust of air through the pillow, thereby causing the pillow to expand and compress. The valve can be adjusted to provide variable resistance and lumbar support to the user.

  • DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
  • [0015]
    As shown in the accompanying drawings for purpose of illustration, the present invention resides in an abdominal exercising device generally referred to by the reference number 10. As shown in FIG. 1, in a preferred embodiment of the invention, the exercise device 10 is in the form of a self-inflating pillow. The pillow is preferably sized to be inserted between a user's lower back and a back rest of a chair or the like. As will be more fully described herein, the exercise device 10 provides a degree of lumbar support while the user is seated and can be adjusted to provide a desired level of resistance for support. To exercise the abdominal and lower back muscles, the user pushes against the exercise device, overcoming the resistance provided by the device and causing it to deflate. To successfully deflate the pillow, the user must utilize his or her abdominal and back muscles. The difficulty level of the exercise can be varied depending on the resistance provided, which movement is resisted to an adjustable degree by the device 10.
  • [0016]
    With reference to FIG. 2, the device 10 includes foam 12 disposed within a cover 14. The cover 14 is preferably of a material which is impermeable to air, or otherwise resists airflow therethrough. In a particularly preferred embodiment, as illustrated, foam 12 comprises two pieces, or is otherwise formed, so as to create a cavity 16 within the device 10.
  • [0017]
    Disposed within the cavity 16 is resistance means 18. In the embodiment shown in FIG. 2, resistance means includes springs 20 disposed between plates 22 and 24. The number and type of springs used can vary according to the desired level of resistance. In a preferred embodiment of the invention, two sets of coiled springs 20 are attached to semi-flexible plates 22 and 24, which can be comprised of plastic or the like. In another preferred embodiment of the invention, the springs can be attached directly to the foam 12, eliminating the need for plates 22 and 24.
  • [0018]
    The springs are preferably biased in an outward direction such that exercise device 10 is in an expanded, decompressed state when no external force is applied to it. Those skilled in the art will understand that any biasing device that biases the pillow in an expanded state can be used. To further assist the device in maintaining an expanded state while at rest, the foam 12 can be shaped and positioned to maintain an expanded volume, defining a cavity therein, when external forces are not applied to the exercise device. Furthermore, in another embodiment of the invention, the foam may comprise shape-memory foam, i.e., constructed of a material that returns to its initial shape and position upon removal of external forces.
  • [0019]
    When performing an exercise, the user exerts force on the exercise device overcoming the resistance provided by the biasing device and causing the exercise device to deflate. A user must utilize his or her abdominal and back muscles to successfully deflate the exercise pillow. AS the exercise device deflates, air from the cavity 16 escapes through air valve 30 (shown in FIG. 1).
  • [0020]
    Once the exercise has been performed, the user relaxes his or her abdominal muscles and back muscles and moves his or her back in a direction away from the exercise device. When the external force from the user is removed, springs 20 push the opposing sides of the device 10 apart from each other to open the central cavity 16 causing air to be introduced into the self-inflating foam. The incoming air is drawn through air valve 30 into the central cavity 16. In alternative embodiments of the invention, springs 20 are not used, as the self-inflating foam will eventually inflate and cause air to be re-introduced into the cavity 16. However, in a preferred embodiment of the invention, the device 10 includes spring 20 and plastic bases 22 and 24 to facilitate the expansion of the exercise device.
  • [0021]
    With reference now to FIGS. 1 and 3 a-3 d, a preferred embodiment of the adjustable air valve 30 is described. Adjustable air valve 30 is preferably a two-way valve, allowing air to escape from the central cavity 16 when the exercise device 10 compresses and allowing air to enter the central cavity 16 when the exercise device expands. It is envisioned that the two-way valve 30 can be replaced with two or more one-way valves known to those skilled in the art. However, it is preferable to utilize a two-way valve that is adjustable, as described further herein.
  • [0022]
    In a preferred embodiment of the invention, valve 30 includes a control knob 32. By rotating the control knob 32, the user can control the size of the valve outlet 34. In a preferred embodiment of the invention, there are three different sized outlets, depicted in FIGS. 3 a through 3 c, respectively. Of the different sized outlets, the outlet 34 a shown in FIG. 3 a has the largest opening. The larger the opening, the less force the user must exert on device 10 to compress it. Therefore, with respect to level of difficulty, the valve setting shown in FIG. 3 a is the easiest setting depicted. FIG. 3 b shows an outlet 34 b having a smaller opening than the outlet 34 a of FIG. 3 a. The valve opening shown in FIG. 3 b corresponds to a moderate or medium setting for level of difficulty. FIG. 3 c shows an outlet 34 c having the smallest opening. This valve setting corresponds to a difficult or advanced level of exercise. FIG. 3 d depicts a valve setting wherein there is no opening and the outlet 34 d is blocked. In this setting, the device 10 cannot be compressed. This setting is most suitable when device 10 is used as a lumbar support device, and not for exercise purposes.
  • [0023]
    FIG. 4 is an exploded view of the valve shown in FIG. 3. As shown in FIG. 4, valve 30 includes a control knob 32, a middle portion defining valve outlets 34, and a cap 36. By turning the control knob 32, the cap 36 turns. The opening in the cap 36 can be aligned with a selected outlet 34 of the middle portion to control the resistance provided in the exercise device.
  • [0024]
    The number of outlet options available and the size of the outlets can vary as desired. Furthermore, the control knob can be configured to move translationally or otherwise control the outflow of air through the valve. In another embodiment of the invention, as shown in FIG. 5, valve 40 includes an upper portion 42 and a lower portion 44 threadingly engaged to each other. The airflow through valve 40 can be adjusted by moving the upper portion 42 with respect to the lower portion 44. For example, as the upper portion is rotated counterclockwise, it will begin to move away from the lower portion 44, allowing for air to flow through passage 46. As the upper and lower portions 42, 44 are further separated, airflow through passage 46 increases.
  • [0025]
    The adjustable valves described herein primarily function to control the difficulty level of the exercise. The smaller the outlet opening, the more force the user will be required to apply to compress the device. To exercise the back and abdominal muscles, the user must repeatedly compress the device. After each compression, the device self-inflates to its initial expanded state and remains in the expanded state until the user's next compression.
  • [0026]
    In a preferred embodiment of the invention, a supplemental valve 50 is provided to reduce the amount of time that the device takes to return to its expanded state. The supplemental valve 50 is preferably a one-way valve that allows air to enter the device when it is self-inflating, but does not allow air to escape from the device. By using a one-way valve, the supplemental valve 50 does not interfere with the exercise level adjustment of valve 30. Rather, supplemental valve 50 only assists in self-inflating the exercise device between compressions.
  • [0027]
    One-way valves are well known in the art. A typical one-way valve, as shown in FIG. 6, includes an upper casing 52 that faces the exterior, a lower casing 54 that faces the interior of the exercise device, a flap 56, and a venting plate 58. When the exercise device 10 is compressed, the air pushes flap 56 against upper casing 52, such that flap 56 blocks the openings 60 in the upper casing 52. Therefore, no air will exit through the supplemental valve 50. In contrast, when the air is drawn into the exercise device, the air pushes flap 56 away from the upper casing 52, allowing for a flow of air through the openings of the upper casing 52, through the venting plate 58, through the openings 60 in the lower casing 54 and into the cavity 16.
  • [0028]
    In a preferred embodiment of the invention, the self-inflating foam 12 will draw air in through the adjustable air valve 30 and the supplemental valve 50. The adjustable air outlet 34 is adjusted to the desired level. The user places the device 10 between the small of his or her back and the back rest of the chair and pushes against the device 10, such as by contracting the abdominal muscles and moving the lower back towards the back rest of the chair, causing the air within the foam 12 to escape through the valve outlet 34. Primarily, it is the forcing of the air through the valve 30 which creates the resistance to exercise the abdominal and back muscles. By opening the valve 30, less resistance is achieved. However, by closing the valve 30, the air escapes more slowly and the resistance is increased.
  • [0029]
    Many modifications and other embodiments of the invention set forth herein will come to mind to one skilled in the art to which the invention pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the invention is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
