Aspects of the disclosure, as described and illustrated herein, can be arranged, combined, modified, and designed in a variety of different formulations, all of which are explicitly contemplated and form part of this disclosure.

Multi-configuration exercise devices described herein include an interface frame operatively coupled to a base frame. Multi-configuration exercise devices contemplated herein include a variety of interface frame heights and orientations, with respect to the base frame. Additionally, devices described herein may include a multitude of configurations achieved by removing one or more pads or coupling one or more pads to the interface frame and/or the base frame. The various configurations of interface frame heights and orientations, with respect to the base frame, have been contemplated to be combined with any pad configuration. The contemplated configurations are intended for a multitude of exercises.

In some embodiments, the exercise devices described herein are configured to save floor space in a gym facility, home gym, living room, office, etc. where the exercise device may be used, while also providing a user with a plurality of configurations to perform various exercises on or using the exercise device. For example, the exercise device, in some configurations, may consume an area with dimensions of about 0.6 m by about 1.4 m on a floor. In some configurations, the exercise device may consume an area with dimensions of about 0.6 m by about 0.6 m area on a floor. In some embodiments, the exercise device is transitionable between two configurations, more than two configurations, a plurality of configurations, three configurations, four configurations, five configurations, or six configurations. In some embodiments, any of the configurations may be used with or without one or more pads or a plurality of pads that are couplable to the interface frame.

illustrate an embodiment of a multi-configuration exercise devicein an example configuration. The configuration shown inmay be used, for example, by a user to perform abdominal exercises (e.g., sit-ups), hamstring exercises (e.g., glute-ham development), and/or lower back exercises (e.g., about 90-degree back extensions). The deviceincludes a base frameand an interface frameoperatively coupled together. When the base frameis laid upon a surface (e.g., the plane defined by the horizontal axisand the normal axis), such that the longitudinal axis(shown in) of the base frameis approximately parallel to the surface, and with gravity acting approximately normal to the surface, the base framerigidly supports and stabilizes the device. The base framemay be operatively coupled to the interface framevia a support beam. Support beammay be hingedly coupled to the base framevia coupling, and the support beammay be hingedly coupled to the interface framevia coupling. The support beammay include a swing bracehingedly coupled to the support beamby coupling. Further, the interface framemay include an arcuate track, which may be reversibly coupled to the support beam. Couplings,may allow rotational adjustment of the support beamand the interface framein a counterclockwise directionabout normal axisand a clockwise directionabout normal axis(shown in). Couplingmay allow rotational adjustment of the swing bracein a counterclockwise directionabout normal axisand a clockwise directionabout normal axis(shown in). The interface framemay include an adjustable length(shown in). Additionally, the interface framemay include a plurality of pads: a first pad, a second pad, a third pad(shown in), first cylindrical padremovably coupled to the interface frame, and a second cylindrical pad. Any of pads,,,,,may be removable or repositionable. For example, the first padmay be removable. For example, the first cylindrical padmay be removable. Additionally, the interface framemay include a base plateand one or more handles. The base framemay include one or more wheelsand one or more weight pegs. The height(as shown in) and orientation of the interface framemay be manipulated with respect to the base frame.

As shown in, embodiments may include a swing bracehingedly coupled to the support beamby coupling. Embodiments utilizing the swing bracemay use the swing bracefor angular adjustments of the support beam. As shown in, the base framemay include a unidirectional adjustment interfacecoupled to the base frame. The unidirectional adjustment interfacemay include a geometric shape, in which the swing brace, when engaged with unidirectional adjustment interface, is adjustable in one direction (e.g., a unidirectional saw-tooth pattern). Selective engagement of the swing bracewith the unidirectional adjustment interfaceadjusts the magnitude of angle(shown in). As such, the support beammay achieve a plurality of adjustments of angle(shown in) while being angled toward a vertical orientation (i.e., aligned with the vertical axisand increasing the angle), and prevented from angling back towards a horizontal orientation (i.e., aligned with the horizontal axis). The swing bracemay be removed from engagement with the unidirectional adjustment interfaceto angle the support beamtoward a horizontal orientation (i.e., aligned with the horizontal axis, decreasing second angle). Said another way, angleis prevented from increasing due to engagement of the swing bracewith the unidirectional adjustment interface, while decreasing the angleis not restrained by the unidirectional adjustment interface. The swing braceincludes a longitudinal axisaligned along couplingand an engaged tooth of the saw-tooth pattern of unidirectional adjustment interface. For example, when the support beamis lifted (i.e., supplying a force including a vector greater than and opposite of gravity, and greater than the resulting weight of the support beam), the engagement of the swing bracewith the unidirectional adjustment interfacewill allow the support beamto rotate about couplingcounterclockwiseabout normal axis. When lifting of the support beamis ceased, engagement of the unidirectional adjustment interfacewith the swing bracemay support the support beamat corresponding angle, even if an additional load is received upon the interface frame. As such, decreasing angledefined by the swing braceand the support beammay increase angledefined by the support beamand the base frame. Increasing angledefined by the swing braceand the support beammay decrease angledefined by the support beamand the base frame.

As shown in, embodiments may include an arcuate trackcoupled to the interface frame. The support beammay define an opening(shown in) in which the arcuate trackinserts within. As shown in, the arcof the arcuate trackis defined by a radius, measured from the coupling(which the interface framerotates about) to the arc. As such, the arcuate trackmay remain within the defined openingof the support beamas an anglebetween the support beamand the interface frameis adjusted. Further, the arcuate trackmay define a plurality of apertures, for example, aperture, aperture, aperture, aperture, aperture, aperture, and one or more additional apertures (not shown). Each aperture of the defined plurality of apertures of the acuate track may be radially arranged such that each aperture is approximately the same radiusfrom the coupling. The support beammay include a spring-loaded pinfor selective engagement with the plurality of apertures of the arcuate track. Said another way, and as shown in, the spring-loaded pinmay be biased such that a portion of the spring-loaded pinmay project into the defined openingof the support beam. The projected portion of the spring-loaded pinmay engage with one of the apertures of the plurality of apertures of the arcuate track. When the projected portion of the spring-loaded pinis engaged with an aperture of the plurality of apertures, for example aperture, aperture, aperture, aperture, aperture, aperture, or one or more additional apertures, anglemay be locked at a corresponding degree amount. For example, when the spring-loaded pinis engaged with aperture, the anglemay be at about five degrees. When the spring-loaded pinis engaged with aperture, the anglemay be at about 10 degrees. When the spring-loaded pinis engaged with aperture, the anglemay be at about 15 degrees. When the spring-loaded pinis engaged with aperture, the anglemay be at about 20 degrees. When the spring-loaded pinis engaged with aperture, the anglemay be at about 25 degrees. When the spring-loaded pinis engaged with an additional aperture (not shown), the anglemay be at about 30 degrees. When the spring-loaded pinis engaged with another aperture (not shown), the anglemay be at about 35 degrees. When the spring-loaded pinis engaged with aperture, the anglemay be at about 40 degrees. Although examples of corresponding degree increments for angleare listed in relation to the plurality of apertures of the arcuate trackand/or are shown in five-degree increments, other degree amounts or increments are contemplated herein. Although an example of eight apertures is given for the plurality of apertures of the arcuate track, more and fewer apertures are contemplated herein. For example, an arcuate trackmay define two to ten apertures, five to 15 apertures, two apertures, three apertures, four apertures, five apertures, six apertures, seven apertures, nine apertures, or ten apertures, and all have been contemplated herein.

For example, the heightof the deviceshown inmay be about 0.75 m to about 1.25 m; about 0.80 m to about 1.20 m; about 0.90 m to about 1.10 m; etc. Orientation of the interface frameis with respect to the base frame. The multi-configuration exercise devicemay include a collapsed configuration as well (as shown in). In the collapsed configuration, angleand angle(shown in) are about zero degrees. Additionally, the longitudinal axis(shown in) of the interface frame, the longitudinal axis(shown in) of the support beam, and the longitudinal axis(shown in) of the base frameare all approximately parallel. The multi-configuration devicemay be adjusted to a fully expanded configuration, a collapsed configuration, or any point there between. Anglemay include an adjustment range of about zero degrees to about 90 degrees; about zero degrees to about 75 degrees; about zero degrees to about 60 degrees; about zero degrees to about 45 degrees; about zero degrees to about 40 degrees; etc. Anglemay include an adjustment range of about zero degrees to about 90 degrees; about zero degrees to about 75 degrees; about zero degrees to about 60 degrees; about zero degrees to about 45 degrees; about zero degrees to about 40 degrees; etc.

The multi-configuration exercise devices described herein include construction with materials with appropriate physical properties and mechanical properties. For example, the interface frame, the base frame, and the support beam may be composed of or comprise materials with the appropriate hardness and strength, for example, alloys (e.g., low-carbon steel, high-carbon steels, mild-carbon steel, stainless steel, aluminum, galvanized steel, etc.), composites, or any other appropriate materials known in the art. For example, pads described herein may be composed in part or solely of appropriate padding material, for example, polyvinyl chloride, thermoplastic elastomer, nitrile butadiene rubber, other rubber variants, foam, cork, neoprene, canvas, or any other appropriate materials known in the art.
