STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

Not applicable to this application.

BACKGROUND
Field

Example embodiments in general relate to an exercise machine which includes a centralized spring box and multiple gripping surfaces with which an exerciser may perform a wide range of exercise moves.

Related Art

Any discussion of the related art throughout the specification should in no way be considered as an admission that such related art is widely known or forms part of common general knowledge in the field.

Exercise machines have become ubiquitous in modern life. A wide range of exercise machines are available for use in both home gyms and in studio gyms catering to multiple exercisers at once. A common exercise machine may include a movable carriage that reciprocates along a track, with one or more bias members being connected to the movable carriage so as to impart a resistance force against movement of the movable carriage in a certain direction.

Such exercise machines may include a number of handles for gripping by the exerciser. However, in the past, the available gripping surfaces on the exercise machine have been limited, thus limiting the availability of exercise moves to be performed on such exercise machines. Such exercise machines typically do not have handles which extend outwardly from the outer ends of the exercise machines so that an exerciser may perform various exercise moves while positioned adjacent to the respective ends of the exercise machine. Further, such exercise machines may not include bias member retainers such as spring boxes which protect the exerciser from the bias members.

SUMMARY

An example embodiment is directed to an exercise machine. The exercise machine includes a carriage which is movably positioned on a track. One or more bias members may be selectively connected between the carriage and various structural elements of the exercise machine so as to impart a resistance force against movement of the carriage along the track. An outer handle may be connected to the carriage so as to surround the carriage platform. One or more inner handles may be positioned between the carriage platform and the outer handle, with the inner handle(s) being connected not to the outer handle or the carriage platform, but to an underlying support assembly. A pair of end handles may extend outwardly from the ends of the exercise machine. A bias member retainer such as a spring box may be centrally-located along the length of the exercise machine.

There has thus been outlined, rather broadly, some of the embodiments of the exercise machine in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional embodiments of the exercise machine that will be described hereinafter and that will form the subject matter of the claims appended hereto. In this respect, before explaining at least one embodiment of the exercise machine in detail, it is to be understood that the exercise machine is not limited in its application to the details of construction or to the arrangements of the components set forth in the following description or illustrated in the drawings.

D. Outer Handle

As shown in FIGS. 1, 2A, 2B, 8A, 8B, and 10, an outer handle 60 may be connected to a support assembly 70 so as to surround the carriage platform 51. The outer handle 60 may extend around the carriage platform 51, with the carriage platform 51 being positioned within the inner perimeter of the outer handle 60. Thus, the outer handle 60 may be positioned to surround the outer perimeter of the carriage platform 51.

The outer handle 60 may comprise a single, continuous handle such as shown in FIGS. 1, 2A, 2B, and 8. In other embodiments, the outer handle 60 may comprise separate handles which are interconnected or coupled together to form the continuous outer handle 60. The outer handle 60 may be comprised of a substantially triangular cross-section such as shown in the figures such that an exerciser may encircle his/her hand around the outer handle 60 at various positions on the outer handle 60 to perform various exercise moves. It should be appreciated, however, that the cross-sectional shape of the outer handle 60 could vary in different embodiments, such as, for example and without limitation, a circular, ovular, square-shaped, or polygonal cross-section.

The outer handle 60 is illustrated as comprising a rectangular-shaped handle with curved corners 144, 145, 146, 147, but may comprise various other shapes and structures in different embodiments. In some embodiments, the outer handle 60 may be circular so as to surround the carriage platform 51. In other embodiments, the outer handle 60 may comprise non-curved corners, such as corners which form right angles.

As best shown in FIG. 18, the outer handle 60 may comprise a first end 140, a second end 141 opposite the first end 140, a first side 142, and a second side 143 opposite the first side 142. The outer handle 60 may be integrally formed, or may be comprised of interconnected portions. The outer handle 60 may include a first corner 144 linking the first side 142 and first end 140 of the outer handle 60, a second corner 145 linking the second side 143 and first end 140 of the outer handle 60, a third corner 146 linking the first side 142 and second end 141 of the outer handle 60, and a fourth corner 147 linking the second side 143 and second end 141 of the outer handle 60. While the figures illustrate an embodiment in which the outer handle 60 comprises four corners 144, 145, 146, 147, it should be appreciated that more or less corners 144, 145, 146, 147 may be utilized in different embodiments.

As shown in the figures, the outer handle 60 is distally-spaced with respect to the carriage platform 51 such that an exerciser may place his/her fingers, hands, toes, feet, or other body parts between the outer handle 60 and the carriage platform 51. In the exemplary embodiment shown in FIGS. 1, 2A, 2B, and 8A, it can be seen that the outer handle 60 extends around the carriage platform 51 of the carriage 50 to form a continuous loop, with gaps or spaces being present between all portions of the carriage platform 51 and the outer handle 50. The outer handle 60 thus is not directly connected to, or in contact with, the carriage platform 51 at any point. Instead, the outer handle 60 is only indirectly connected to the carriage platform 51 by the support frame 71.

As best shown in FIGS. 8A and 10, the outer handle 60 may be connected to a support frame 71, with the support frame 71 being connected to the lower end of the outer handle 60 in the exemplary embodiment shown in the figures. However, it should be appreciated that, in some embodiments, one or more structural elements of the support frame 71 may instead be connected to the inner side of the outer handle 60. The figures illustrate an embodiment in which the outer handle 60 is not directly connected to the carriage 50, but is instead connected to the same support frame 71 to which the carriage 50 is connected. In this manner, the outer handle 60 and carriage 50 may be interconnected by the support frame 71. In some embodiments, however, the outer handle 60 may at one or positions be connected directly to the carriage 50.

As best shown in FIGS. 8B and 10, the support frame 71, which is discussed in more detail below, may include front supports 72, 73 and rear supports 74, 75 which are connected to the outer handle 60. In the exemplary embodiment shown in FIGS. 8A-11, it can be see that the first front support 72, the second front support 73, the first rear support 74, and the second rear support 75 are each connected at a respective corner of the outer handle 60.

Each of the supports 72, 73, 74, 75 may include a bracket, fastener, or the like which connected or secures the outer handle 60 to the support frame 71. In the exemplary embodiments shown in FIGS. 8A and 10, it can be seen that the first front support 72 includes a first front bracket 130, the second front support 73 includes a second front bracket 132, the first rear support 74 includes a first rear bracket 134, and the second rear support 75 includes a second rear bracket 136.

Each of the brackets 130, 132, 134, 136 may comprise a plate-like member which extends upwardly from the respective front and rear supports 72, 73, 74, 75. In the figures, the brackets 130, 132, 134, 136 each extend at a right angle with respect to their respective underlying supports 72, 73, 74, 75. However, in certain embodiments, the brackets 130, 132, 134, 136 may extend at other angles from the underlying supports 72, 73, 74, 75. Thus, the brackets 130, 132, 134, 136 may extend vertically upward, or may extend diagonally upward.

Each of the brackets 130, 132, 134, 136 includes a cutout 131, 133, 135, 137 in which the outer handle 60 is positioned and secured as discussed herein and shown in FIG. 18. The shape and size of the cutouts 131, 133, 135, 137 may vary in different embodiments. In the exemplary embodiments shown in the figures, the cutouts 131, 133, 135, 137 are shown as comprising a substantially semi-circular shape. In other embodiments, various other shapes may be utilized, such as but not limited to V-shaped and U-shaped cutouts 131, 133, 135, 137. Thus, the scope should not be construed as limited to any particular shape or size of cutout 131, 133, 135, 137 so long as the outer handle 60 may be positioned within and secured to the cutouts 131, 133, 135, 137.

The manner in which the outer handle 60 is connected to the brackets 130, 132, 134, 136 may vary in different embodiments. The outer handle 60 may be positioned within and secured within the cutouts 131, 133, 135, 137 of each bracket 130, 132, 134, 136 in different manners. By way of example and without limitation, the outer handle 60 may be secured by use of adhesives, welding, clamps, fasteners, ties, and the like.

As shown in FIG. 18, the first front support 72 includes a first front bracket 130 which extends upwardly from the first front support 72. The first front bracket 130 includes a first front cutout 131 within which a portion of the outer handle 60 may be positioned and secured. In the exemplary embodiment shown in the figures, the first front bracket 130 is positioned underneath the first side 142 of the outer handle 60 near the first end 140 of the outer handle 60. Thus, the first front bracket 130 may be positioned underneath the first side 142 of the outer handle 60 near the first corner 144 of the outer handle 60. It should be appreciated, however, that the first front bracket 130 may be positioned at other locations along the outer handle 60 in different embodiments.

The second front support 73 includes a second front bracket 132 which extends upwardly from the second front support 73. The second front bracket 132 includes a second front cutout 133 within which a portion of the outer handle 60 may be positioned and secured. In the exemplary embodiment shown in the figures, the second front bracket 132 is positioned underneath the second side 143 of the outer handle 60 near the first end 140 of the outer handle 60. Thus, the second front bracket 132 may be positioned underneath the second side 143 of the outer handle 60 near the second corner 145 of the outer handle 60. It should be appreciated, however, that the second front bracket 132 may be positioned at other locations along the outer handle 60 in different embodiments.

The first rear support 74 includes a first rear bracket 134 which extends upwardly from the first rear support 74. The first rear bracket 134 includes a first rear cutout 135 within which a portion of the outer handle 60 may be positioned and secured. In the exemplary embodiment shown in the figures, the first rear bracket 134 is positioned underneath the first side 142 of the outer handle 60 near the second end 141 of the outer handle 60. Thus, the first rear bracket 134 may be positioned underneath the first side 142 of the outer handle 60 near the third corner 146 of the outer handle 60. It should be appreciated, however, that the first rear bracket 134 may be positioned at other locations along the outer handle 60 in different embodiments.

The second rear support 75 includes a second rear bracket 136 which extends upwardly from the second rear support 75. The second rear bracket 136 includes a second rear cutout 137 within which a portion of the outer handle 60 may be positioned and secured. In the exemplary embodiment shown in the figures, the second rear bracket 134 is positioned underneath the second side 143 of the outer handle 60 near the second end 141 of the outer handle 60. Thus, the second rear bracket 136 may be positioned underneath the second side 143 of the outer handle 60 near the fourth corner 147 of the outer handle 60. It should be appreciated, however, that the second rear bracket 136 may be positioned at other locations along the outer handle 60 in different embodiments.

In this manner, the outer handle 60 may be connected to the support frame 71, which itself is connected to and supports the carriage platform 51. Thus, the outer handle 60 is not in contact with or directly connected with the carriage platform 51. Although the figures illustrate four points of connection between the outer handle 60 and the support frame 71 (the front brackets 130, 132 of the front supports 72, 73 connected to the underside near the front corners 144, 145 of the outer handle 60 and the rear brackets 134, 136 of the rear supports 74, 75 connected to the underside near the rear corners 146, 147 of the outer handle 60), it should be appreciated that more or less connection points may be utilized to secure the outer handle 60 to the underlying support frame 71 such that the outer handle 60 extends around, but is not directly connected to, the carriage platform 51.

The outer handle 60 is configured such that an exerciser may grasp the outer handle 60 at a wide range of locations surrounding the carriage platform 51. By limiting the connection points between the outer handle 60 and the carriage platform 51, the exerciser is provided a wide range of grasping points both on the outer handle 60 and on the outer edges of the carriage platform 51 itself. The gap or space between the carriage platform 51 and the outer handle 60 allows an exerciser to place his/her feet, hands, fingers, etc. between the carriage platform 51 and the outer handle 60 so as to grasp the outer handle 60 and/or the carriage platform 51 when performing a wide range of exercise moves.

E. Inner Handles

As best shown in FIGS. 1, 2A, 2B, 4, 8A, 8B, and 10, the carriage 50 may include inner handles 62a, 62b, 64a, 64b. Each of the inner handles 62a, 62b, 64a, 64b may be positioned between the carriage platform 51 and the outer handle 60, but none of the inner handles 62a, 62b, 64a, 64b are connected directly to, or in contact with, either the carriage platform 51 or the outer handle 60. As shown in the figures, none of the inner handles 62a, 62b, 64a, 64b are in contact with either the outer handle 60 or the carriage 50. In this manner, the inner handles 62a, 62b, 64a, 64b appear to “float” when viewed from the top such as shown in FIG. 8A.

The shape, size, positioning, and number of inner handles 62a, 62b, 64a, 64b may vary in different embodiments. In the exemplary embodiment shown in the figures, a first inner handle 62a is positioned between a first side 57 of the first end portion 53 of the carriage platform 51 and the outer handle 60, without being in contact with either the carriage platform 51 or the outer handle 60. A second inner handle 62b is also positioned between a second side of the first end portion 53 of the carriage platform 51 and the outer handle 60, without being in contact with either the carriage page 51 or the outer handle 60. Both of the first and second inner handles 62a, 62b may extend at a right angle with respect to the track 30 as shown in the figures.

Continuing to reference FIG. 8A, a third inner handle 64a is positioned between a first side of the second end portion 54 of the carriage platform 51 and the outer handle 60, without being in contact with either the carriage platform 51 or the outer handle 60. A fourth inner handle 64b is also positioned between a second side of the second end portion 54 of the carriage platform 51 and the outer handle 60, without being in contact with either the carriage platform 51 or the outer handle 60. Both of the third and fourth inner handles 64a, 64b may extend at a right angle with respect to the track 30 as shown in the figures.

The figures illustrate an exemplary embodiment in which each of the inner handles 62a, 62b, 64a, 64b extends horizontally between the carriage 50 (e.g., the carriage platform 51 of the carriage 50) and the outer handle 60. Such an orientation is perpendicular with respect to the direction of the track 30. In such an orientation, the inner handles 62a, 62b, 64a, 64b are each parallel with respect to the linkages 61a, 61b, 61c, 61d connected between the carriage platform 51 and the outer handle 60.

However, it should be appreciated that other orientations of the inner handles 62a, 62b, 64a, 64b may be utilized in different embodiments. For example, each of the inner handles 62a, 62b, 64a, 64b may extend diagonally, with, for example, the first end of each of the inner handles 62a, 62b, 64a, 64b being at a higher elevation than the second end of each of the inner handles 62a, 62b, 64a, 64b, or vice versa.

FIGS. 12A, 12B, 12C, and 12D illustrate exemplary embodiments of each of the inner handles 62a, 62b, 64a, 64b. FIG. 12A illustrates a first inner handle 62a, FIG. 12B illustrates a second inner handle 62b, FIG. 12C illustrates a third inner handle 64a, and FIG. 12D illustrates a fourth inner handle 64b.

As shown in FIGS. 12A, 12B, 12C, and 12D, each of the inner handles 62a, 62b, 64a, 64b comprising a gripping surface adapted to gripped by an exerciser during performance of various exercise moves. The shape of such gripping surfaces may vary in different embodiments, and may comprise, by way of example and without limitation, circular cross-sections, triangular cross-sections, square cross-sections, or polygonal cross-sections. Each of the inner handles 62a, 62b, 64a, 64b may comprise bands at or near their respective outer ends which serve to prevent the hand or feet of an exerciser from sliding or slipping off the outer ends of each of the inner handles 62a, 62b, 64a, 64b.

Continuing to reference FIGS. 12A, 12B, 12C, and 12D, it can be seen that each of the inner handles 62a, 62b, 64a, 64b comprises a pair of handle connectors 63a, 63b, 65a, 65b, 66a, 66b, 67a, 67b. The handle connectors 63a, 63b, 65a, 65b, 66a, 66b, 67a, 67b may comprise plates, brackets, clamps, or the like which are utilized to secure the inner handles 62a, 62b, 64a, 64b not to the outer handle 60 or to the carriage 50, but instead to a support assembly 70 underlying the carriage 50.

The handle connectors 63a, 63b, 65a, 65b, 66a, 66b, 67a, 67b are preferably shaped and sized so as to connect the inner handles 62a, 62b, 64a, 64b to the support frame 71 such that the inner handles 62a, 62b, 64a, 64b are neither connected to nor in contact with the carriage platform 51 or the outer handle 60 as shown in the figures. By connecting the inner handles 62a, 62b, 64a, 64b to the underlying support assembly 70, rather than to the outer handle 60 or the carriage 50, the inner handles 62a, 62b, 64a, 64b may have the appearance of “floating” carriage handles, especially when viewing the carriage 50 from the top such as shown in FIG. 8.

In the embodiment shown in the figures, the first connector 63a, 65a, 66a, 67a of each inner handle 62a, 62b, 64a, 64b is comprised of a vertically-oriented bracket structure adapted to connect to the support frame 71 or, more specifically, to the front and rear supports 72, 73, 74, 75 of the support frame 71. In contrast, the second connector 63b, 65b, 66b, 67b of each inner handle 62a, 62b, 64a, 64b is comprised of a slanted, or diagonal orientation.

The use of a slated or diagonal orientation of the second connector 63b, 65b, 66b, 67b of each inner handle 62a, 62b, 64a, 64b allows the second connectors 63b, 65b, 66b, 67b to connect to the support frame 71 underneath the carriage platform 51 while still allowing a gap or space between each inner handle 62a, 62b, 64a, 64b and the carriage platform 51 as shown in the figures. This type of configuration also prevents the need for portions of the support frame 71 (e.g., the cross supports 76, 77) from extending outwardly from the sides of the lower end of the carriage platform 51.

With reference to FIG. 12A, it can be seen that the first inner handle 62a comprises a first handle connector 63a and a second handle connector 63b. With reference to FIG. 12B, it can be seen that the second inner handle 62b comprises a first handle connector 65a and a second handle connector 65b. With reference to FIG. 12C, it can be seen that the third inner handle 64a comprises a first handle connector 66a and a second handle connector 66b. With reference to FIG. 12D, it can be seen that the fourth inner handle 64b comprises a first handle connector 67a and a second handle connector 67b.

As discussed in more detail below, the handle connectors 63a, 63b, 65a, 65b, 66a, 66b, 67a, 67b are utilized to connect the inner handles 62a, 62b, 64a, 64b to a support assembly 70 underlying the carriage 50. In this manner, the inner handles 62a, 62b, 64a, 64b may be disconnected from, and thus not in contact with, either the outer handle 60 or any portion of the carriage platform 51.

As shown in the figures, there is a gap or space between the outer ends of the respective inner handles 62a, 62b, 64a, 64b and the inner end of the outer handle 60. Similarly, there is a gap or space between the inner ends of the respective inner handles 62a, 62b, 64a, 64b and the outer end of the carriage platform 51, thus producing the “floating” effect discussed herein, particularly when viewing the carriage 50 from the top.

F. Support Assembly

Each of the inner handles 62a, 62b, 64a, 64b is supported not by being connected to either the carriage platform 51 or the outer handle 60, but instead by a support assembly 70 connected to the lower end of the carriage 50. The support assembly 70 is best shown in FIG. 8B which illustrates the support assembly 70 with the carriage 50 removed and FIG. 10 which illustrates the underside of the carriage 50 to which the support assembly 70 is connected.

As shown, the support assembly 70 may comprise a support frame 71 of structural supports 61a, 61b, 61c, 61d, 72, 73, 74, 75, 76, 77 to which the carriage 50 may be connected and by which the carriage platform 51 may be supported, with the underside of the carriage platform 51 being secured to and supported by the support frame 71. In some embodiments, the carriage 50 may include the support assembly 70 (e.g., the carriage 50 and support assembly 70 may be integrally formed). In other embodiments, the support assembly 70 may be connected to the carriage 50.

As best shown in FIG. 10, the support frame 71 may comprise a first front support 72 and a second front support 73.

H. Operation of Preferred Embodiment

The various embodiments of an exercise machine 10 described and shown herein may be utilized in a variety of manners by an exerciser to perform a wide range of exercise moves. The exercise machine 10 will generally be positioned on a ground surface, such as a floor, with the footings 41a, 41b, 45a, 45b, 48a, 48b contacting the ground surface. An exerciser may then place portions of his/her body, including but not limited to the torso, arm(s), leg(s), hand(s), feet, head, neck, etc. on various portions of the exercise machine 10. By way of example and without limitation, the exerciser could place his/her hands on an end platform 80, 85 and his/her feet on the carriage 50. The carriage 50 may be moved back and forth along at least a portion of the track 30, with any bias members 92 connected to the carriage 50 provided a resistance force against movement of the carriage 50 in a direction.

To select the resistance level, the exerciser 10 may select how many of the bias members 92 are connected to the carriage 50. Any desired bias members 92 may be retrieved from the bias member retainer 90 and then removably connected to the carriage bias receiver 94. When the carriage 50 is in its resting position, the carriage bias receiver 94 may be directly on top of the bias member retainer 90 to ease transfer of any desired bias members 92 from the bias member retainer 90 to the carriage bias receiver 94, or vice versa.

The exerciser may select how many bias members 92 to secure to the carriage 50 prior to moving the carriage 50. Generally, connecting more bias members 92 to the carriage 50 will increase the resistance of the carriage 50 to being moved in a certain direction, and connecting less bias members 92 to the carriage 50 will decrease the resistance of the carriage 50 to being moved in a certain direction. The positioning of the bias member retainer 90 at a central location along the frame 20, underneath the resting carriage 50, eases the transferring of bias members 92 from the carriage 50 to the bias member retainer 90 and vice versa. Preferably, the bias member retainer 90 is positioned directly underneath the resting position of the carriage 50 such as shown in the figures. The bias member retainer 90 includes an opening 91 at its front end out of which the bias members 92 extend.

The bias retainer 90 provides for preventing the bias members 92 from being exposed to an exerciser during an exercise, and further, in the event of the occasional failure of a bias member 92 under tension, prevents the violently retracting portion of the failed bias member 92 from striking the exerciser, and prevents damage to other components of the exercise machine 10.

The exerciser may use one or more of the inner handles 62a, 62b, 64a, 64b when performing a wide range of exercises. As discussed previously, the inner handles 62a, 62b, 64a, 64b are not connected to either the carriage 50 or the outer handle 60, but instead are connected to support structures of a support assembly 70 which is connected to the underside of the carriage 50. In this regard, the inner handles 62a, 62b, 64a, 64b appear to be “floating”, particularly when viewing the carriage 50 from its upper end.

The inner handles 62a, 62b, 64a, 64b may be gripped by the exerciser when performing exercises, sometimes in combination with gripping the outer handle 60 and/or other gripping surfaces of the carriage 50. The inner handles 62a, 62b, 64a, 64b may be gripped by the hands of the exerciser, or the exerciser may position other body parts on the inner handles 62a, 62b, 64a, 64b to perform various exercises which involve moving the carriage 50 along the track 30 in various manners. By way of example and without limitation, the exerciser may place his/her feet on the inner handles 62a, 62b, 64a, 64b to aid in moving the carriage 50 along the track 30.

The end handles 100, 105 may also be utilized by the exerciser in performing various exercises with the exercise machine 10. For example, the exerciser may stand, kneel, sit, or otherwise position himself or herself adjacent to the exercise machine 10, but not on the exercise machine 10, and grip one of the end handles 100, 105 to perform various exercises. Alternatively, the exerciser may position himself or herself on one of the end platforms 80, 85 and grip the one of the end handles 100, 105 to perform various exercise movements. A wide range of exercise moves, either involving the carriage 50 or not, may benefit from the use of one or both of the end handles 100, 105 which extend outwardly from the respective ends 21, 22 of the frame 20 of the exercise machine 10. The end handles 100, 105 may also function as steps to aid the exerciser with stepping onto or off of the exercise machine 10.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although methods and materials similar to or equivalent to those described herein can be used in the practice or testing of the exercise machine, suitable methods and materials are described above.
