DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference will now be made in detail to presently preferred embodiments of the disclosure, one or more examples of which are illustrated in the accompanying drawings. Each example is provided by way of explanation, not limitation, of the invention. In fact, it will be apparent to those skilled in the art that modifications and variations can be made in the present invention without departing from the scope and spirit thereof. For instance, features illustrated or described as part of one embodiment may be used on another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.
Referring now to the figures, as shown in FIG. 1, an embodiment of an abdominal exercise device 10 in accordance with the present disclosure includes at least a first elongated member 20a, a padded member 40 disposed thereabout, and an attachment assembly 50 for releasably securing exercise device 10 to a support surface, preferably padded, such as a mattress 12 (FIGS. 5 and 6). Additionally, as discussed in greater detail below, exercise device 10 may include additional elongated members 20b, 20c and 20d, dependent upon the width of the support surface to which exercise device 10 is secured.
Referring additionally to FIGS. 2A and 2B, and as noted above, various configurations of exercise device 10 may include multiple elongated members. As shown, first elongated member 20a includes a first end 22, a second end 24, and an inner surface 28 that defines an elongated bore 26. Padded member 40 also includes an elongated bore 42 that is defined by an inner surface that is received adjacent an outer surface 30 of first elongated member 20a. Preferably, first elongated member 20a is a cylindrical metal tube measuring 19 inches in length and having a 1 inch outer diameter. The 19 inch length for the elongated members is preferable in that when exercise device 10 is secured to a standard sized mattress 12, as shown in FIGS. 5 and 6, two elongated members can be used to span a twin, three sections to span a full or queen, and four sections to span a king. Note, although the elongated members are preferably cylindrical, they may also be formed from tubes of varying cross-sectional shapes (oval, rectangular, polygonal, etc.) and materials other than steel (fiber reinforced plastic, fiberglass, etc.) that exhibit sufficient rigidity for the intended purpose.
As shown, padded member 40 is preferably cylindrical, formed of a polymer foam material, has an outer diameter of 31⁄2 inches, and an overall length of 19 inches that corresponds to the length of first elongated member 20a. Elongated bore 42 of padded member 40 is correspondingly shaped to the cross-sectional shape of first elongated member 20a. Additionally, the external cross-sectional shape of padded member 40 may be varied (oval, rectangular, polygonal, etc.)
In the configuration of exercise device 10 shown in FIGS. 2A and 2B, at least a second elongated member 20b is utilized. Second elongated member 20b differs only from first elongated member 20a in that a connector stub 34 is received in its elongated bore 26 at its first end 22. Connector stub 34 is sized and configured such that a first portion 36 of connector stub 34 is received in elongated bore 26 of second elongated member 20b in a press-fit. Preferably, the press-fit of first portion 36 in elongated bore 26 is sufficient to prevent removal of connector stub 34 from second elongated member 20b. However, dependent upon the materials used to construct connector stub 34 and the corresponding elongated member, first portion 36 of connector stub 34 may be further secured in the elongated bore 26 by welding, gluing, crimping, staking, etc. A second portion 38 of connector stub 34 is removably received in elongated bore 26 of first elongated member 20a at its second end 24 in an interference fit. As such, first elongated member 20a and second elongated member 20b are selectively connectable by the user in the interference fit, thereby preventing their separation until an adequate amount of force in opposing axial directions is applied by the user.
Referring additionally to FIGS. 3 and 4, attachment assembly 50 includes a strap 52 with a first end 54 and a second end 56, and a buckle 58 with a first male portion 60 secured to first end 54 of strap 52 and a second female portion 62 attached to second end 56 of strap 52. As shown in FIG. 1, male end 60 of buckle 58 is selectively removable from strap 52. This is desirable in order to facilitate threading strap 52 through elongated bores 26 of the various elongated members 20a, 20b, 20c and 20d, that may be used in a specific configuration of abdominal exercise device 10. After first end 54 of strap 52 has been threaded through the elongated bores of the elongated members, male end 60 is secured to strap 52 and the desired length of strap 52 may be adjusted by sliding one, or both, of first and second portions 60 and 62 along the length of strap 52.
Preferably, strap 52 is comprised of nylon and is 18 feet in length and 11⁄2 inches in width, whereas buckle 58 is constructed of plastic. Alternate materials may be used for both the strap and the buckle. The length of strap 52 allows exercise device 10 to be used on mattresses 12 (FIGS. 5 and 6) that range in size from a single up to a king. As shown, strap 52 is preferably passed under the box spring on which mattress 12 is supported to provide additional stability. As well, the length of strap 52 allows the user to position the strap around the bed frame on which mattress 12 and box spring are positioned if desired. Strap 52 can be threaded through the corresponding elongated bores 26 either prior to (FIG. 4) or after (FIG. 3) the various elongated members 20a, 20b, 20c and 20d are secured to each other. Note, attachment assembly 50 can also be used to attach the exercise device support surfaces other than bedding, for example, but not limited to, couches, lounge chairs, etc.
As shown in FIGS. 7A and 7B, in an alternate embodiment of abdominal exercise device 10b, connector stub 34 as used with the first embodiment is replaced with a first portion 23, or mounting stub, of second elongated member 20b that is received in a second portion 25, or mounting bore, of first elongated member 20a. More specifically, exercise device 10b differs from exercise device 10a in that first portion 23 of second elongated member 20b is formed integrally therewith rather than using a separate connector stub to connect the elongated members.
In yet another alternate embodiment of abdominal exercise device 10c, the various elongated members used may be assembled with a threaded connection. For example, as shown in FIGS. 8A and 8B, second elongated member 20b includes an externally threaded first portion 23, or mounting stub, that is selectively connectable to an internally threaded second portion 25, or mounting bore, of first elongated member 20a. Alternately, as shown in FIGS. 9A and 9B, adjacent elongated members 20a and 20b can each include an externally threaded first portion 23 that is selectively engagable with an internally threaded mounting bore 72 of a threaded nut 70.
Referring now to FIGS. 5 and 6, exercise device 10 is shown secured to mattress 12. More specifically, exercise device 10 is secured to a king size mattress 12 and, as such, four elongated members 20a, 20b, 20c and 20d have been coupled together such that the device spans the entire width of the mattress. Note, however, fewer than four elongated members can be used if desired. To perform exercises, a user positions a portion of his body between the elongated members 20a-20d and the mattress in order to anchor that portion of his body to the mattress. As shown in FIG. 6, the user has positioned both feet under the elongated members in order to perform abdominal exercises. Note, however, the user may also position his head adjacent exercise device 10 and grasp elongated members 20a-20d with his hands. In this manner, exercises such as leg lifts may be performed.
When not in use, buckle 58 can be used to disconnect the first and second ends of strap 52 such that elongated members 20a-2d can be positioned off to the side of mattress 12 to allow for its unencumbered use. Alternately, the entire exercise device can be removed simply by removing strap 52 from between mattress 12 and its box spring. As shown in FIG. 4, elongated members 20a-20d can be readily separated from each other while maintaining strap 52 positioned therethrough. This partial disassembly facilitates repositioning exercise device 10 on the mattress when desired, yet allows the device to be folded for easy storage, carrying in luggage, etc.
While one or more preferred embodiments of the invention are described above, it should be appreciated by those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope and spirit thereof. For example, the cross-sectional shapes of the elongated members may be of any shape found to be suitable for the intended purpose. Additionally, the components of the exercise device may be constructed of any material found to be suitable for the intended purpose. It is intended that the present invention cover such modifications and variations as come within the scope and spirit of the appended claims and their equivalents.
