STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT
Not Applicable.
FIELD OF THE INVENTION
This invention relates to exercise devices, and more particularly to a multi-use exercise bench and foot docking station.
DISCUSSION OF RELATED ART
The prior art is replete with exercise devices for allowing a user to perform a number of different exercise. Often it is desired that exercise devices allow for a large number of different exercises that exercise a multiple number of muscle groups, such as the torso, core, mid-section, rectus abdominals, transversus abdominis, lower back, internal oblique, external oblique, latissimus dorsi, serratus anterior, serratus posterior inferior, erector spinae, external intercoastal, gluteus maximus, and gluteus medius muscle groups. Heretofore, however, any exercise device that purports to allow exercise of many of these muscle groups is relatively bulky and difficult to transport, store and use.
Therefore, there is a need for a device that allows exercising of all of these muscle groups through versatile adjustment of height, angle, and rotation of various components thereof. Such a needed device would be relatively compact when collapsed into a retracted position for ease of transportation and storage. Such a needed invention would further be relatively inexpensive to manufacture, and easy to set-up, reconfigure and use. The present invention accomplishes these objectives.
SUMMARY OF THE INVENTION
The present device is an exercise apparatus for use by a person on a support surface, such as a floor. A foot docking station comprises a base plate pivotally fixed to a back plate at a hinge. The back plate includes a central pivot rotationally fixed with a bottom side of a foot plate. The rotational hinge preferably includes a selectively adjustable tightening knob adapted to lock the rotational position of the back plate and foot plate with the base plate.
The foot plate has a shin engagement mechanism extending away from a top side thereof for engaging the shins of the person while the person's feet contact the top side of the foot plate, or at least a cushion affixed thereto. The shin engagement mechanism includes a pair of U-shaped shin pads projecting laterally away therefrom.
Preferably the base plate and foot plate further include a rotational locking mechanism adapted for selectively locking the relative rotational position between the back plate and the foot plate. The base plate further includes a weight rod projecting upwardly therefrom and adapted to receive at least one annular weight thereon. Alternately, a door or other heavy item may be engaged with the weight rod or base plate to maintain the base plate on the support surface.
The foot docking station further includes a first receiver and the exercise apparatus further includes a lower bench. The lower bench comprises an elongated lower shaft having a distal end adapted for engaging the first receiver of the foot docking station, and a proximal end.
In one embodiment, each of two rigid distal legs is fixed with the distal end of the lower shaft at a rotational leg mount. The distal legs are positionable between a retracted position aligned with and adjacent to the lower shaft, and an extended position extending beyond the distal end of the lower shaft. The rotational leg mount includes a rotational lock adapted for selective locking of the relative rotational position of the legs and the lower shaft. The legs preferably each terminate at a distal end thereof with a surface grip.
As such, with the proximal end of the lower shaft and the surface grips of each leg contacting the support surface, the height and angle of the foot docking station and the lower bench may be selected for performing the exercise.
The first embodiment of the distal legs may also include, at the proximal end of each distal leg, a vertical pivot adapted to allow the distal leg to pivot laterally outwardly away from the distal end of the lower shaft. The vertical pivot is captured within a pivot housing that may further include a plurality of pin stops. In such an embodiment, the proximal end of each leg further includes a spring-biased pin adapted for engaging any of the plurality of pin stops of the pivot housing to selectively lock the pivoting position of the leg with respect to the lower shaft.
In a second and preferred embodiment of the legs of the invention, the pair of legs takes the form of a single T-shaped leg having a main shaft and two laterally projecting shafts. An axle traverses a proximal end of the T-shaped leg and a pivot aperture of a second pivot housing. The pivot housing further includes at least one locking plate through which a locking pin can engage any one of a plurality of pin stops to selectively lock the relative rotational position of the T-shaped leg and the lower shaft. The distal end of the lower shaft and the first receiver of the foot docking station may include a pin locking mechanism, such that a locking pin may be selectively used to lock the foot docking station to the distal end of the lower shaft.
The proximal end of the lower shaft of the lower bench further includes a second receiver for engaging an upper bench. An elongated upper shaft has a distal end adapted for engaging the second receiver of the lower shaft, and a proximal end. At least one proximal leg is fixed with the proximal end of the upper shaft at a rotational leg mount at a proximal end thereof, identically to either the first or second embodiment of the at least one distal leg except oriented-degrees such that the at least one proximal leg may extend beyond the proximal end of the upper shaft when in its extended position. Each proximal leg terminates at a distal end thereof with the surface grip.
In such an embodiment, the distal end of the upper shaft and the second receiver of the lower shaft include a second pin locking mechanism, such that a locking pin may be used to selectively lock the proximal end of the lower shaft to the distal end of the upper shaft.
A top side of the upper shaft includes a track upon which a bench trolley slides between the proximal and distal ends of the upper shaft. The bench trolley includes at least one cushion at a top side thereof, a pair of laterally extending handles, and at least a first pair of wheels that engage the track. The bench trolley may further include a lumbar support cushion extending away from a distal side thereof.
The track preferably includes a plurality of locking apertures and the bench trolley includes a pin aperture. As such, the bench trolley can be locked into position with respect to the track by inserting a locking pin through the pin aperture of the bench trolley and one of the plurality of locking apertures of the track. The track further may include at least one pair of wheel cut-outs, the bench trolley including a wheel post extending through the track of the upper shaft and terminating in a second pair of wheels that engage an inside surface of the upper shaft. As such, when the second pair of wheels is aligned with the cut-outs the bench trolley can be removed from the upper bench.
Preferably a third pair of wheels extends past the proximal end of the upper shaft. The foot docking station, in such an embodiment, includes a pulling handle formed in a distal end of the base plate. As such, with the proximal and distal legs, each in their retracted positions, the pulling handle of the foot docking station may be lifted and pulled to roll the apparatus along the support surface upon the third pair of wheels. Similarly, the distal end of the lower shaft may also include one of the pulling handles such that the apparatus may be rolled along the support surface even if the foot docking station is removed from the lower shaft.
An auxiliary bench may be attached to the upper and lower benches, by removing the bench trolley and, optionally, the foot docking station. The auxiliary bench may be selectively attached to the upper and lower benches, or to the track, at a pair of mechanical fasteners. An optional seat attachment may be selectively fixed with the distal end of the auxiliary bench. As such, by positioning the proximal and distal legs, in their various positions, the auxiliary bench may be reclined, inclined, or level.
The present device allows exercising of the torso, core, mid-section, rectus abdominals, transversus abdominis, lower back, internal oblique, external oblique, latissimus dorsi, serratus anterior, serratus posterior inferior, erector spinae, external intercoastal, gluteus maximus, and gluteus medius muscle groups through versatile adjustment of height, angle, and rotation of various components of the apparatus. The present device is relatively compact when collapsed into a retracted position for ease of transportation and storage, and is relatively inexpensive to manufacture, easy to set-up, reconfigure and use. Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

FIGS. 1-3 illustrate an exercise apparatus 10 for use by a person 20 on a support surface 15, such as a floor. A foot docking station 30 comprises a rigid, preferably metallic base plate 40 pivotally fixed to a rigid, preferably metallic back plate 50 at a hinge 60. The back plate 50 includes a central pivot 55 rotationally fixed with a bottom side 72 of a rigid, preferably metallic foot plate 70. The rotational hinge 60 preferably includes a selectively adjustable tightening knob 65 (FIG. 2) adapted to frictionally lock the rotational position of the back plate 50 and foot plate 70 with the base plate 40. In one embodiment, radially-aligned sawtooth teeth (not shown), as is known in the art, within the rotational hinge 60 provide for discrete angular adjustment of the foot plate 70 with the base plate 40 in increments of 8 to 10-degrees. As such, the rotational position of the back plate 50 and foot plate 70 with the base plate 40 may be selectively set if desired by the person 20.
The foot plate 70 has a shin engagement mechanism 80 extending away from a top side 78 thereof for engaging the shins 22 of the person 20 while the person's feet 24 contact the top side 78 of the foot plate 70 or a cushion 79 affixed thereto. The shin engagement mechanism 80 includes a pair of U-shaped shin pads 82 projecting laterally away therefrom (FIG. 4, which has one of the shin pads 82 omitted for clarity of illustration). Optionally the cushioned shin pads 82 may be fixed on a shin pad trolley 84 that is adjustably moved closer or farther away from the foot plate 70 with a trolley movement mechanism 86 that may include a threaded rod 88 and a rotational knob 89, or other similar mechanism for moving the pair of shin pads 82 up and down with respect to the foot plate 70.

An axle 333 traverses a proximal end 332 of the T-shaped leg 330 and a pivot aperture (not shown) v of a second pivot housing 340. The pivot housing 340 further includes at least one locking plate 346 through which a locking pin 350 can engage any one of a plurality of pin stops 347 to selectively lock the relative rotational position of the T-shaped leg 330 and the lower shaft 120.
The distal end 128 of the lower shaft 120 and the first receiver 100 of the foot docking station 30 may include a pin locking mechanism 170 (FIGS. 6 and 12B), such that a locking pin 176 may be selectively used to lock the foot docking station 30 to the distal end 128 of the lower shaft 120.
Preferably the proximal end 122 of the lower shaft 120 of the lower bench 110 further includes a second receiver 180 for engaging an upper bench 190 (FIGS. 7-13C). A rigid, preferably metallic, elongated upper shaft 200 has a distal end 208 adapted for engaging the second receiver 180 of the lower shaft 120, and a proximal end 202. At least one proximal leg 210 is fixed with the proximal end 202 of the upper shaft 200 at a rotational leg mount 140 at a proximal end 212 thereof, identically to either the first or second embodiment of the at least one distal leg 130 except oriented 180-degrees such that the at least one proximal leg 210 may extend beyond the proximal end 202 of the upper shaft 200 when in its extended position 160. Each proximal leg 210 terminates at a distal end 218 thereof with the surface grip 139.
