DETAILED DESCRIPTION
Referring now to the drawings wherein like reference numerals identify similar structures, element, and features, various embodiments of the presently disclosed exercise apparatus will be discussed.
The exercise apparatus of the present invention provides a lightweight portable device. The apparatus is foldable to case carrying size so it can easily be transported by the user. Several embodiments of the exercise apparatus are illustrated in the drawings and described below. Note the apparatus can be used for butt toning (gluteus maximus) exercises, but is not limited to butt toning exercises as it can also be used for other exercises for other parts of the user's body, e.g., shoulders, triceps, biceps, etc.
Turning first to FIGS. 1-4, these Figures illustrate one embodiment of the exercise apparatus of the present invention, which is identified generally by the reference character 100. The apparatus 100 includes an upper (head) body portion 102u, a lower (leg, foot) body portion 102l, and one or more resistance (training) members 104. The body portions 102u, 102l are connected to each other such that the apparatus 100 is reconfigurable between a closed configuration (also referred to herein as a first, collapsed, or folded configuration) as shown in FIG. 1, which facilitates transport and/or storage of the apparatus 100, and an open configuration (also referred to herein as a second, expanded, or unfolded configuration) as shown in FIGS. 2-4, which allows for use of the apparatus 100. In the open position, the apparatus 10 (and upper and lower body portions) are placed in a substantially horizontal position. Substantially horizontal refers to a position on the floor or other supporting surface which can be parallel to the floor (flat on the floor) or slightly inclined with respect to the floor. In this manner, the user is kneeling on the apparatus over the upper surfaces of the upper and lower body portions. This horizontal position should be differentiated from a vertical position which is parallel to a wall (transverse to the floor).
In the particular embodiment of the disclosure seen in FIGS. 1-4, in the open configuration, it is envisioned that the apparatus 100 may define an overall length L (FIG. 4) that lies substantially within the range of approximately 2′ (feet) to approximately 4′ (feet), and in more preferred embodiments, approximately 3′, and an overall width W that lies substantially within the range of approximately 1.5′ (feet) to approximately 4′ (feet), and in preferred embodiments, approximately 2′. It should be appreciated, however, that larger and smaller widths and lengths of the apparatus 100 would be within the scope of the present invention. Also, different shapes of the body portions are disclosed which can be symmetrical or asymmetrical.
In the particular embodiment of the disclosure seen in FIGS. 1-4, the apparatus 100 includes one or more tethers 106, e.g., one or more straps, living hinges, etc., (FIG. 2) that extend between and connect the body portions 102u, 102l. In such embodiments, it is envisioned that the tether(s) 106 may be integrally (e.g., monolithically) formed with the body portion 102u and/or the body portion 102l or, alternatively, that the tether(s) 106 may be separate component(s) of the apparatus 100. To increase versatility of the apparatus 100, it is envisioned that the tether(s) 106 may be configured so as to define an adjustable length Lt (FIG. 2) to allow the spacing between the body portions 102u, 102l to be varied when the apparatus 100 is in the open configuration, thus allowing for use by a wider range of user (e.g., taller and shorter individuals) and increasing user comfort. For example, it is envisioned that the tether(s) 106 may include a ratcheting mechanism, strap with spaced loops, adjustable screws, or any other such suitable components and/or structures/mechanisms that enables length adjustment. In this manner, the distance between body portions 102u and 102l can be increased or decreased to adjust for the height of the user, e.g., for taller individuals the mechanism would be adjusted so that the spacing between body portions 102u, 102l increases and for shorter individuals the mechanism would be adjusted so that the spacing between body portions 102u, 102l would be decreased. Alternatively, it is envisioned that in alternate embodiments, the tether(s) 106 may be configured such that the length between the body portions 102u, 102l is fixed.
In alternate embodiments, the tether(s) 106 may be omitted and the body portions 102u, 102l may be connected to each other via a hinge member (e.g., one or more pivot pins, rods, etc.) that extends into (through) the body portions 102u, 102l. In these embodiments, the distance between the body portions 102u, 102l would not be adjustable, although in certain embodiments, they can be directly attached with a distance adjustable feature.
To improve portability of the apparatus 100, in some embodiments, either or both of the body portions 102u, 102l may include a handle 108 (FIGS. 1, 3, 4) and one or more lightweight materials may be utilized in construction of the body portions 102u, 1021. For example, it is envisioned that the body portions 102u, 102l may include (e.g., may be formed partially or entirely from) one or more non-metallic materials (e.g., plastic(s), polymers, carbon fiber, etc.) and/or one or more metallic materials (e.g., aluminum, steel, etc.). In the particular embodiment of the disclosure seen in FIGS. 1-4, the apparatus 100 includes material(s) of construction that are selected such that an overall weight of the apparatus 100 lies within the range of approximately 3 lbs. to approximately 7 lbs. (e.g., approximately 5 lbs.). It should be appreciated, however, that lighter and heavier embodiments of the apparatus 100 would be within the scope of the present disclosure (e.g., to increase durability, strength, etc.). It is also envisioned that the apparatus 100 may be formed through any suitable method of manufacture, such as, for example, injection molding, stamping, casting, 3-D printing, etc. Different shaped handles to facilitate carrying of the apparatus are also contemplated, and the handles can be attached to various regions of the body portions.
The body portion 102u includes an inner (top or upper) surface 110ui (FIG. 3) that faces the user in the open position of the apparatus and an outer (bottom or lower) surface 110uo (FIG. 4) that faces the floor in the open in-use position. It is envisioned that the inner surface 110ui may be either (generally) planar (flat) in configuration or that the inner surface 110ui may be non-planar in configuration. For example, the inner surface 110ui may include an overall curvature. The inner surface 110ui may include one or more recessed regions to accommodate the user's arms (hands, elbows, forearms) during use of the apparatus 100. To increase user comfort, the upper body portion 102u may include one or more cushioning members 112 (e.g., pads), as shown in FIGS. 2 and 3, that are positioned to support the user's arms (hands, elbows, forearms). While the cushioning member(s) 112 are shown as including a generally elongated (e.g., generally rectangular or generally elliptical) configuration in the particular embodiment of the apparatus 100 seen in FIGS. 1-4, it should be appreciated that the size and configuration of the cushioning member(s) 112 may be varied in alternate embodiments without departing from the scope of the present invention, as discussed below.
To maintain proper positioning and/or increase stability of the apparatus 100 during use, the outer surfaces 110uo, 11010 of the respective body portions 102u, 102l may include one or more non-slip (friction) members 114 (e.g., rubberized pad(s)) (FIG. 4) to increase friction with the surface supporting the apparatus 100 (e.g., the floor). Additionally, or alternatively, the outer surfaces 110uo, 110lo of the respective body portions 102u, 102l may include texturing (e.g., dimpling) to further improve stability of the apparatus 100 during use. The non-slip members for both body portions can be of varying sizes and configurations and one or multiple non-slip members can be provided.
Thus, as used herein, the inner (top/upper) surface of the body portions refers to the surface facing the user and the outer (bottom/lower) surface of the body portions refers to the surface facing the floor.
To improve user control and/or comfort during use of the apparatus 100, the body portion 102u may include one or more gripping portions (members) 116 (FIG. 3). In certain embodiments, the gripping portion(s) 116 may be integrally (e.g., monolithically) formed with the body portion 102u. For example, the gripping portion(s) 116 may include contoured sections of the body portion 102u that are configured to receive (or otherwise accommodate) the user's hands and/or fingers. Additionally, or alternatively, the gripping portion(s) 116 may include one or more fixed or removable handle members (e.g., bars, etc.), as discussed in further detail below. In such embodiments, the gripping portion(s) 116 may be adjustable to increase versatility of the apparatus 100 and/or user comfort, e.g., movable with respect to the body portion 102u to increase its distance from the outer edge of the body portion 102u. To further increase user comfort, the gripping portion(s) 116 may in some embodiments include padding or other such cushioning material(s).
In the illustrated embodiment, to connect the resistance members to the body portion 102u, the body portion 102u includes one or more engagement members 118 (FIG. 3). The resistance members 104 are in some embodiments releasably engageable (connectable) to the engagement members 18. More specifically, in the particular embodiment shown in FIGS. 1-4, the body portion 102u includes a pair of eyelets 120 (or other such members) extending from its upper surface 110ui that are configured for connection of corresponding engagement structure 122 (e.g., hooks) on the resistance member(s) 104. In alternate embodiments of the disclosure, however, the engagement member(s) 118 may be omitted from the body portion 102u and the resistance members 104 non-removably connected to the body portion 102u. The resistance members 104 in alternate embodiments can be non-removably connected to the engagement members. In the embodiments wherein the resistance members 104 are releasably connected to the upper body portion 102u, e.g., via a hook/eyelet structure, resistance members having a greater or lesser degrees of resistance can be utilized to accommodate the specific user. For example, for increased resistance, resistance members 104 of less resistance can be removed and replaced by resistance members having greater resistance and vice versa. The resistance members 104 can be in the form of elastic stretchable bands or other tensioning members.
The lower body portion 102l includes an inner (top or upper) surface 1101i (FIG. 3) and an outer (bottom or lower) surface 11010 (FIG. 4). As with the body portion 102u, the inner surface 1101i may be either (generally) planar (flat) in configuration or the inner surface 1101i may be non-planar in configuration. For example, the inner surface 1101i may include an overall curvature and/or the inner surface 1101i may include one or more recessed regions to accommodate the user's legs (knees, shins) during use of the apparatus 100. To increase user comfort, the body portion 102l may include one or more cushioning members 112 (e.g., pads), as shown in FIGS. 2 and 3, that are positioned to support the user's legs (knees, shins). The configuration and number of cushioning members 112 in the upper and lower body portions 110u and 110l can vary from that shown.
As discussed in connection with the body portion 102u, the outer surface 110lo of the body portion 102l, as shown in the embodiment of FIG. 4, may include one or more non-slip (friction) members 114 (e.g., a rubberized pad) to increase friction with the surface supporting the apparatus 100 (e.g., the floor) and, thus, maintain proper positioning and/or increase stability of the apparatus 100 during use. Additionally, or alternatively, the outer surface 110lo of the body portion 102l may include texturing (e.g., dimpling) to further improve stability of the apparatus 100 during use.
In the illustrated embodiment, the body portion 102l further includes one or more engagement members 118 (FIG. 3) that are configured for releasable connection of the resistance member(s) 104. More specifically, in the particular embodiment shown in
FIGS. 1-4, the body portion 102l includes a pair of eyelets 120 (or other such members) that are configured to receive the corresponding engagement structure 122 (e.g., hooks) on the resistance member(s) 104. Alternatively, the eyelets can be on the resistance members 104 and the engagement structure, e.g., hooks, on the body portion 102l and/or body portion 102u). Other types of engagement/attachment structure are also contemplated. In alternate embodiments of the disclosure, the engagement member(s) 118 may be omitted from the body portion 102l. As such, embodiments of the apparatus 100 are envisioned in which the resistance member(s) 104 are connectable to each of the body portions 102u, 102l, as are embodiments in which the resistance member(s) 104 are connectable to either the body portion 102u or the body portion 102l.
To increase user stability, it is envisioned that the body portion 102l may also include one or more rests 124 (FIG. 2) that are configured to support the user during use of the apparatus. In the particular embodiment of the apparatus 100 seen in FIGS. 1-4, for example, the body portion 102l includes a pair of foot blocks 126 each configured to receive a foot of the user. It is also envisioned that the body portion 102u may include one or more similar blocks that are configured to support the user's arms (e.g., elbows). The rests 124 project upwardly from the surface of the body portion 102l, and can include in some embodiments a cup shape for the user's heel or other configurations to accommodate other portion of the user's foot, to facilitate the user's positioning of the user's body on the upper and lower body portions 102u, 102l of the apparatus 100. As shown, the foot rests are separate from the resistance members.
In various embodiments, it is envisioned that the rest(s) 124 may be either fixedly (e.g., integrally) connected to the body portion 102l or that the rest(s) 124 may be non-fixedly (e.g., movably) connected to the body portion 1021. For example, the rest(s) 124 may be repositionable between a variety of locations, e.g., repositionable along the length of the body portion 102l, to allow for use by a wider range of user (e.g., taller and shorter individuals) and/or repositionable along the width of the body portion 102l. In certain embodiments, the rests 124 can be removable from the body portion 102l.
With continued reference to FIGS. 1-4, the resistance member(s) 104 will be discussed. Each resistance member 104 includes a tactile or body engagement portion 128 (e.g., a foot-loop 130, a handle, etc.) (FIGS. 2, 3) that allows the user to securely interact with the resistance member(s) 104 and the apparatus 100. For example, in the method of use illustrated in FIG. 2, the user interacts with the resistance member(s) 104 by placing her/his foot into an opening defined by the foot loop 130. It should be appreciated, however, that the specific configuration of the tactile portion 128 may be altered or varied in alternate embodiments of the disclosure to allow for various interactions by the user such that a variety of exercises can be performed using the apparatus 100.
In the particular embodiment illustrated in FIGS. 1-4, the apparatus 100 is illustrated as including four resistance members 104i-104iv (FIG. 2) that are configured to offer resistance that lies substantially within the range of approximately 5 lbs. to approximately 100 lbs. however, other ranges are also within the scope of the present disclosure. A fewer or greater number of resistance members are also contemplated.
The resistance members 104 may be either identical or non-identical. For example, the resistance members 104 may be configured to provide different resistances to increase the versatility of the apparatus 100 and the spectrum of available training. In such embodiments, the apparatus 100 may, thus, be provided as a kit that includes a series of different resistance members 104 (e.g., one or more of the resistance members 104i, one or more of the resistance members 104ii, one or more of the resistance members 104iii, one or more of the resistance members 104iv, etc.) which can be of different lengths, widths, tensions, etc.
Referring still to FIGS. 1-4, a method of using the apparatus 100 will be discussed. The apparatus can be used as a butt toner, i.e., for gluteus maximus training, although as discussed herein, other uses are also contemplated. Initially, the apparatus 100 is moved from the closed configuration (FIG. 1) to the open configuration (FIGS. 2-4) such that the respective outer surfaces 110uo, 110lo of the body portions 102u, 102l (and the non-slip members 114) are in suitable contact with the surface supporting the apparatus 100 (e.g., the floor) so the user can use the apparatus in a bent kneeling or prone-like position, e.g., facing the floor as shown in FIG. 2. Once opened, in the embodiments having releasably connectable resistance members, the select resistance member(s) 104 can be connected to the body portion 102u and/or to the body portion 102l by connecting the engagement structure(s) 122, e.g., a hook, on the resistance member(s) 104 to the engagement member(s) 118 (e.g., the eyelet(s) 120) on the body portion 102u and/or the body portion 1021. For example, when the apparatus 100 is utilized in the manner illustrated in FIG. 2 (e.g., to exercise the user's legs and gluteus maximus), the user may elect to connect the resistance member(s) 104 to the body portion 102u or to the body portion 102l based on the desired level of resistance. For any given resistance member 104, it is envisioned that the resistance offered may be increased via connection to the body portion 102u and decreased via connection to the body portion 102l due to the resultant relative increase or decrease in the range of motion determined by the point of connection. More specifically, in the context of FIG. 2, by connecting the resistance member(s) 104 to the body portion 102u, the range of motion and the resistance offered can be increased when compared to the range of motion and the resistance offered by connecting the resistance member(s) 104 to the body portion 102l.
Following connection of the resistance member(s) 104 to the body portion 102u and/or the body portion 102l, the user can position herself/himself on the apparatus 100 as desired, preferably in the kneeling position facing downward toward the floor utilizing the knee cushions of the lower body portion 102u and hand/elbow/forearm cushions of the upper body portion 102l. As noted above, the user can also lie on the user's side to perform other exercises or stand or kneel with the back upright (facing the wall) to perform other exercises for different body muscles. Thus, depending upon the particular exercise being performed, the user may utilize the cushioning members 112 to increase the comfort of the user's arms and/or legs.
After completion of the exercise regimen, the resistance member(s) 104 can be disconnected (removed) from the body portion 102u and/or the body portion 102l and the apparatus 100 can be moved from the open configuration (FIGS. 2-4) to the closed configuration (FIG. 1) and stored for later use. As shown in FIG. 1, the closed configuration of the apparatus 100 provides a lightweight portable exercise apparatus.
With reference now to FIGS. 5-10, various alternate embodiments of the apparatus 100 will be discussed. More specifically, FIGS. 5 and 6 illustrate an embodiment of the apparatus that is identified generally by the reference character 200, FIGS. 7 and 8 illustrate an embodiment of the apparatus that is identified generally by the reference character 300, and FIGS. 9 and 10 illustrate an embodiment of the apparatus that is identified generally by the reference character 400. Each apparatus 200, 300, 400 is substantially similar to the apparatus 100 discussed above with respect to FIGS. 1-4 and, accordingly, will only be discussed with respect to any difference(s) therefrom in the interest of brevity. Thus, the discussion herein of the function and features of apparatus 100 of FIGS. 1-4 and the alternate versions are fully applicable to each apparatus of FIGS. 5-10.
In contrast to the generally ovate (elliptical) configuration of the apparatus 100 seen in FIGS. 1-4, the apparatus 200 of FIG. 5 includes a generally rectangular configuration with radiused corner portions. More specifically, the apparatus 200 includes an upper body portion 202u with radiused corner portions 232ui, 232uii, 232uiii and 232uiv and a lower body portion 202l with radiused corner portions 232li, 232lii, 232liii and 232-232liv.
The upper body portion 202u includes gripping portions(s) 216 that are configured as handle members 234, which may be either fixedly (e.g., integrally) or non-fixedly (e.g., movably) connected to the body potion 202u. As mentioned above, in certain embodiments, the handle members 234 may be adjustable to increase versatility of the apparatus 200 and/or user comfort. The lower body portion 2021 includes cushioning members 212 (e.g., pads) that are generally circular in configuration, rather than elongated, as seen in FIG. 3 and in upper body portion 202u, for example. In this embodiment, the upper and lower body portions 202l and 202u are attached, e.g., tethered, by connectors 206 a fixed distance, however, alternatively, they can be adjustable to adjust the distance between the upper and lower body portions 202u, 202l, as discussed above with regard to apparatus 100. Several connectors 206 can be provided, or alternatively a single in this embodiment and in the other embodiments disclosed herein.
To maintain proper positioning and/or increase stability of the apparatus 200 during use, as discussed in connection with the apparatus 100 (FIGS. 1-4), it is envisioned that each of the body portions 202u, 202l may include one or more non-slip (friction) members 214 (e.g., rubberized pad(s)) (FIG. 6) on its bottom surface to increase friction with the surface supporting the apparatus 200 (e.g., the floor). The resistance members are designated by reference numeral 204 and are configured to function like resistance members 104i-104iv and can be connected to the body portions in the ways described herein.
Referring now to FIGS. 7 and 8, the apparatus 300 includes a generally circular configuration. The apparatus 300 includes body portions 302u, 302l that each includes support bars 336 (or other such members). The connectors 306 connect the body portions 302u, 302l and in some embodiments can be adjustable to adjust the distance between the body portions 302u, 302l. In some embodiments, the connector 306 can be connected to the support bar 306. The pads are designated by reference numeral 312, the foot blocks are designated by reference numeral 326, non-slip (friction) members (e.g., rubberized pad(s)) to increase friction are designated by reference numeral 314 and the resistance members are designated by reference numeral 304 and are configured to function like resistance members 104i-104iv. Two resistance members 304 can be provided by way of example as shown, however, additional resistance members could also be provided. The resistance members can be attached to the support bar or attached to the upper body portions.
Referring now to FIGS. 9 and 10, the apparatus 400 includes respective upper and lower body portions 402u, 402l as well as one or more biasing members 438 that extend therebetween (e.g., to generally maintain spacing between the body portions 402u, 402l when the apparatus 400 is in the open configuration, assist with opening and/or closure of the apparatus 400, etc.). In the illustrated embodiment, for example, the biasing member(s) 438 are configured as coil springs. It should be appreciated, however, that the particular configuration of the biasing member(s) 438 may be varied in alternate embodiments without departing from the scope of the present invention. The upper and lower body portions 402u, 402l can be a fixed distance or in alternate embodiments adjustable at connector(s) 406. The connector(s) 406 can be in the form of a ratchet to allow for adjustability or can be in the forms as explained above. The pads are designated by reference numeral 412 and the resistance members are designated by reference numeral 404 and are configured to function like resistance members 104i-104iv.
