DESCRIPTION OF THE PREFERRED EMBODIMENTS
The detailed embodiments of the present invention are disclosed herein. It should be understood, however, that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, the details disclosed herein are not to be interpreted as limiting, but merely as a basis for teaching one skilled in the art how to make and/or use the invention.
Referring to the various figures, an exercise apparatus 10 using the weight of the individual exercising as a resistance source is disclosed. The exercise apparatus 10 includes a mounting assembly 12 and a pulley assembly 14 coupled to the mounting assembly 12. The pulley assembly 14 includes a support bar 16 from which a coupling bar 18 extends. The coupling bar 18 is used in releasably securing the pulley assembly 14 to the mounting assembly 12. The pulley assembly 14 also includes a first pulley 20 and a second pulley 22 extending from the support bar 16. A first pulley cable 24 is positioned about the first pulley 20 for movement relative thereto and a second pulley cable 26 is positioned about the second pulley 22 for movement relative thereto. The first pulley cable 24 includes a first end 28 and a second end 30 and the second pulley cable 26 includes a first end 32 and a second end 34. A first handle 36 is coupled to the first end 28 of the first pulley cable 24 and a second handle 38 is coupled to the first end 32 of the second pulley cable 26. A body engaging assembly 40 is coupled to both the second end 30 of the first pulley cable 24 and the second end 34 of the second pulley cable 26.
Referring now to FIGS. 1, 2 and 3, the mounting assembly 12 is adapted for selective attachment to a door 42 by positioning the mounting assembly 12 between the door 42 and the door frame 44 such that a first end 46 of the mounting assembly 12 is positioned on an exterior side 48 of the door 42 during exercise and a second end 50 of the mounting assembly 12 is positioned on an interior side 52 (that is, within the room where the user will be exercising) of the door 42 during exercise. The first end 46 is therefore provided with an abutment member 54 in the form of an elongated bar 56 having enlarged cushioned end members 58, 60 of a size such that the elongated bar 56 is too big to pass within the space between the door 42 and the door frame 44. The second end 50 of the mounting assembly 12 is provided with a releasable coupling member 62 in the form of a carabiner, which, as will be appreciated based upon the following disclosure, allows for selective attachment of the pulley assembly 14 to the mounting assembly 12. The releasable coupling member 62 at the second end 50 of the mounting assembly 12 is secured to the abutment member 54 at the first end 46 of the mounting assembly 12 by a strap 64 shaped and dimensioned to pass between the exterior side 48 of the door 42 and the interior side 52 of the door 42 with the strap 64 fitting within the space between the door 42 and the door frame 44.
Turning now to the pulley assembly 14 as shown best with reference to FIGS. 1, 4 and 5, the pulley assembly 14 includes a support bar 16 from which the coupling bar 18 and the first and second pulleys 20, 22 extend. The support bar 16 includes a first end 66 and second end 68, with a central section 70 between the first end 66 and the second end 68. The coupling bar 18 is secured to the support bar 16 at approximately the longitudinal center of the support bar 16 and extends in a direction perpendicular to the longitudinal axis of the support bar 16.
An adjustable coupling strap 72 is used in securing the pulley assembly 14 to the mounting assembly 12, in particular, in securing the pulley assembly 14 to the releasable coupling member 62 at the second end 30 of the mounting assembly 12. The adjustable coupling strap 72 includes a first end 74 and a second end 76. The first end 74 of the adjustable coupling strap 72 is provided with a coupling ring 78 (for example, an O-ring) shaped and dimensioned for selective attachment to the releasable coupling member 62 and the second end 76 of the coupling strap 72 is provided with a releasable coupling member 80 in the form of a carabiner that is shaped and dimensioned for selective coupling with an O-ring 82 at the free end 84 of the coupling bar 18. In this way, the adjustable coupling strap 72 may be selectively secured between the pulley assembly 14 and the mounting assembly 12 to secure the functional components of the present exercise apparatus 10 to the door 42.
As mentioned above, the coupling strap 72 is adjustable. In accordance with a preferred embodiment, this is achieved by forming the coupling strap 72 from two strap members 86, 88 with a buckle 90 positioned between. The first strap member 86, which forms the first end 74 of the coupling strap 72 is of a fixed length and is fixedly secured to the O-ring 78 and the buckle 90. The second strap member 88, which forms the second end 76 of the coupling strap 72 is of an adjustable operating length and passes through the buckle 90 for selective attachment thereto in a manner allowing for adjustment of the effective length of the adjustable coupling strap 72. The second strap member 88 includes a first end 92 to which the releasable coupling member 80 is secured and a free, second end 94. The second strap member 88 is moved and locked relative to the buckle 90 so as to adjust the length of the second strap member 88 extending between the buckle 90 and the releasable coupling member 80. It is appreciated the buckle 90 is a conventional spring based locking buckle using a pivoting and spring biased latching member 96 to control movement of the second strap member 88 relative to the buckle 90.
The pulley assembly 14 also includes a first pulley 20 and a second pulley 22 extending from the support bar 16. The first pulley 20 is secured to the first end 66 of the support bar 16 in a manner permitting a full range of motion of the first pulley 20 relative to the support bar 16. Similarly, the second pulley 22 is secured to the second end 68 of the support bar 16 in a manner permitting a full range of motion of the second pulley 22 relative to the support bar 16. A full range of motion, as well as releasable attachment of the first and second pulleys 20, 22 to the respective ends 66, 68 of the support bar 16, is achieved by providing the first end 66 and the second end 68 of the support bar 16 with first and second O-rings 98, 100. The first and second pulleys 20, 22 are secured to the O-rings 98, 100 using first and second releasable coupling members 102, 104, in particular, carabiners, from which the first and second pulleys 20, 22 extend.
Considering now the first and second pulleys 20, 22, they are conventional pulleys and may take various forms. In accordance with a preferred embodiment, each of the first and second pulleys 20, 22 includes a U-shaped frame member 106. The U-shaped frame member 106 includes a first end 108 at the connection member 110 coupling the first and second arms 112, 114 at a second end 116 at the free ends of the first and second arms 112. The first end 108 includes an O-ring 118 to which the releasable coupling member 102, 104 is secured and the second end 116 includes a pivot pin 120 extending between the free ends of the first and second arms 112, 114 with a wheel 122 rotating upon the pivot pin 120.
As mentioned above, a first pulley cable 24 is secured to the first pulley 20 and a second pulley cable 26 is secured to the second pulley 22. With reference to the first pulley cable 24, it passes within the space defined by the U-shaped frame member 106 between the first end 108, which is closed by the connection member 110, and the second end 116, which is closed by the pivot pin 120 and wheel 122. The first pulley cable 24 is retained within the spaced defined by the U-shaped frame member 106 by securing a first locking ball 124 adjacent the first end 28 of the first pulley cable 24 and a second locking ball 126 adjacent the second end 30 of the first pulley cable 24. The first and second locking balls 124, 126 are larger than the space defined by the U-shaped frame member 106 and the respective first and second ends 28, 30 of the first pulley cable 24 may not be pulled through the space defined by the U-shaped frame member 106 so as to effectively remove the first pulley cable 24 from the first pulley 20. Similarly, the second pulley cable 26 is retained within the spaced defined by the U-shaped frame member 106 by securing a first locking ball 128 adjacent the first end 32 of the second pulley cable 26 and a second locking ball 130 adjacent the second end 34 of the second pulley cable 26. The first and second locking balls 128, 130 are larger than the space defined by the U-shaped frame member 106 and the respective first and second ends 32, 34 of the second pulley cable 26 may not be pulled through the space defined by the U-shaped frame member 106 so as to effectively remove the first pulley cable 24 from the first pulley 20.
The first pulley cable 24 includes a first end 28 and second end 30. A first handle 36 is coupled to the first end 28 of the first pulley cable 24, at a position beyond the previously discussed first locking ball 124. The body engaging assembly 40 is coupled to the second end 30 of the first pulley cable 24 at a position beyond the previously discussed second locking ball 126. The first handle 36 and the body engaging assembly 40 are releasably secured to the first pulley cable 24. In accordance with a preferred embodiment the first and second ends 28, 30 of the first pulley cable 24, as well as the first handle 36 and the body engaging assembly 40 are provided with O-rings that are releasably connected together as described above using releasable coupling members 132, 133 in the form of carabiners. With regard to the second pulley cable 26, it includes a first end and second end 32, 34. The second handle 38 is coupled to the first end 32 of the second pulley cable 26, at a position beyond the previously discussed first locking ball 128. The body engaging assembly 40 is coupled to the second end 34 of the second pulley cable 26 at a position beyond the previously discussed second locking ball 130. The second handle 38 and the body engaging assembly 40 are releasably secured to the first pulley cable 24. In accordance with a preferred embodiment the first and second ends 32, 34 of the second pulley cable 26, as well as the second handle 38 and the body engaging assembly 40 are provided with O-rings that are releasably connected together as described above using releasable coupling members 134, 135 in the form of carabiners. Further versatility may be achieved through the provision of gripping balls formed adjacent the first ends of the first and second pulley cables. These gripping balls would allow for exercises where handles are not optimal and permit a user to grip the first end of the respective first and second pulley cables at positions slightly displaced from the actual ends of the cables where a shorter effective cable length is desired.
Considering now the body engaging assembly 40, it is preferably a belt 134 shaped and dimensioned for positioning about the waist of a user as he or she exercises. As such, the belt 134 includes an elongated body 136 with an inner surface 138 and an outer surface 140, as well as a first end 142 and a second end 144. The respective first end 142 and second end 144 are provided with first and second mating fastening members 146, 148 allowing for releasable attachment of the belt 134 about the waist of a user. The belt 134 is primarily composed of a central wide strap member 150 from which adjustable straps 152, 154 (using conventional buckles 158 to allow for adjustment) extend at both the first end 142 of the belt 134 and the second end 144 of the belt 134. In accordance with a preferred embodiment, the ends of the wide strap member 150 are provided with elastic allowing for stretching of the wide strap member 150 to accommodate various body positions for different exercises, as well as various body sizes without the need for the larger scale adjustments permitted by the adjustable straps 152, 154.
With regard to the attachment of the second ends 30, 34 of the first and second pulley cables 26, 28 to the elongated body 136 of the body engaging assembly 40, the elongated body 136 is constructed such that the O-rings 137, 139 used in securing the second ends 30, 34 of the first and second pulley cables 24, 26 to the elongated body 136 are positioned along the outer surface 140 of the elongated body 136, that is, the surface of the elongated body 136 facing away from the user when the body engaging assembly 40 is properly positioned about the waist of the user.
More particularly, the O-rings 137, 139 are positioned such that they are substantially aligned with opposed sides of the body along front plane of the user's body; that is, the O-rings, 137, 139, when the belt 134 is properly secured about the user will be positioned at the left and right sides of the body
As will be further appreciated when the variety of uses for the present exercise apparatus is explained below, and as discussed above, the belt 134 includes an elastic feature allowing for positioning of the belt 134 at various locations along the abdomen and torso of the user. In particular, the belt 134 includes a left side panel 162 adjacent the first end of belt 134 and a right side panel 164 adjacent the second end of the belt 134. Each of the first side panel and the right side panel is provided with an elastic member allowing for controlled expansion thereof. In addition, it is appreciated additional security can be achieved by extending a tether from the mounting assembly 40 to the belt 134.
In use, the present exercise may be thought of as “a gym in a bag.” In particular, the body engaging assembly 40 is provided with a zippered pouch 141 in which the various functional components of the present exercise apparatus 10 may be stored. In accordance with a preferred embodiment, the pouch 141 is secured to the belt 134 using hook and loop fasteners 160 allowing for selective attachment thereto.
When it is time to exercise, the user removes the various functional components, that is, the mounting assembly 12 and the pulley assembly 14. The abutment member 54 is positioned on the exterior side of the door 42 and the strap 64 is slid between the door 42 and the door frame 44. In particular, the strap 64 is slid between the door 42 and the door frame 44 from the top of the door 42 such that the strap 64 sits upon the upper hinge connecting the door 42 to the door frame 44.
With the abutment member 54 positioned on the exterior of the door 42 and the strap 64 extending to the interior of the door 42, the adjustable coupling strap 72 is secured to the strap 64 and the pulley assembly 14 is secured to the adjustable coupling strap 72. The user then secures the body engaging assembly about his or her torso or waist depending upon the exercise. The second ends 30 of the pulley cables are then secured to the attachment points of the body engaging assembly 40. At this point, the user may adjust the adjustable coupling strap 72 to suit the specific exercise he or she plans to perform. In particular, the adjustable coupling strap 72 is adjusted such that the user may use his or her complete weight from the ground up, meaning that he/she will lift his/her whole weight from the ground up, but spreading the load all over his/her body. Thereafter, the user may grip the handles and begin exercising.
As a result, the user becomes the weight and can either lean forward or backward while performing various exercises. For example, the present exercise apparatus will allow the user to do back, squats, shoulders, biceps, triceps etc. with his/her body functioning as the resistance weight.
In the case where the user desires to do a chest workout, he/she may lean forward with the belt 134 positioned at a comfortable position as shown in FIG. 5. When he/she is doing butterflies or he/she is doing push-ups or shoulders he/she can lean, he/she can go down and come up in one motion using his/her whole body. Because he/she is at an angle, his/her body has to flex all its front muscles to keep him/her straight up. You can do back exercises, upper chest exercises, lower chest exercises, sit-ups etc.
Referring to FIGS. 7 to 20 an alternate embodiment of the present invention is disclosed. As with the prior embodiment, the exercise apparatus 1010 includes a mounting assembly 1012 and a pulley assembly 1014 coupled to the mounting assembly 1012.

With regard to the attachment of the second ends 1030, 1034 of the first and second pulley cables 1026, 1028 to the elongated body 1136 of the body engaging assembly 1040, the elongated body 1136 is constructed such that the releasable coupling members 1069, 1071 used in securing the second ends 1030, 1034 of the first and second pulley cables 1024, 1026 to the elongated body 1136 are positioned along the outer surface 1140 of the elongated body 1136, that is, the surface of the elongated body 1136 facing away from the user when the body engaging assembly 1040 is properly positioned about the waist of the user.
More particularly, the releasable coupling members 1069, 1071 are positioned such that they are substantially aligned with opposed side of the body along the front plane of the user's body; that is, the releasable coupling members 1069, 1071, when the belt 134 is properly secured about the user will be positioned at the left and right sides of the body
As will be further appreciated when the variety of uses for the present exercise apparatus is explained below, and as discussed above, the belt 1134 includes an elastic feature allowing for positioning of the belt 1134 at various locations along the abdomen and torso of the user. In particular, the belt 1134 includes a left side panel 1162 adjacent the first end of belt 1134 and a right side panel 1164 adjacent the second end of the belt 1134. Each of the left side panel 1162 and the right side panel 1164 is provided with an elastic member 1162a, 1164b allowing for controlled expansion thereof. In addition, it is appreciated additional security can be achieved by extending a tether from the mounting assembly 1040 to the belt 1134.
Further versatility is achieved by the provision of a central pulley assembly 1310 (see FIGS. 16, 17 and 18). The central pulley assembly 1310 includes a short strap member 1312 to which a central pulley 1314 is secured. The central pulley 1314 is supported upon the short strap member 1312 via a bearing 1313 allowing for a wide range of motion. The bearing 1313 includes a removable pin 1313p allowing for release of the central pulley 1314 from the short strap member 1312. The remainder of the bearing 1313 is the same as the frame 1106 described above with regard to the first and second pulleys 1020, 1022. As will be appreciated based upon the following disclosure, the central pulley assembly 1310 allows for adjustment of the present exercise device from a dual pulley assembly to a single pulley assembly where a single pulley cable 1316 extends through a tortuous path joining the first pulley 1022, the second pulley 1022 and the central pulley assembly 1310.
The short strap member 1312 of the central pulley assembly 1310 includes a first end 1318 provided with a releasable coupling member 1320 adapted for attachment to the releasable coupling member 1069 on the left side of the belt 1134 and a second end 1322 provided with a releasable coupling member 1324 adapted for attachment to the releasable coupling member 1071 on the right side of the belt 1134. With the first and second ends 1318, 1322 of the central pulley assembly 1310 secured to the belt 1134, the central pulley 1314 is positioned across the front of the belt 1134 at a position along the abdomen of the user.
As mentioned above, this alternative uses a single pulley cable construction. The single pulley cable 1316 includes a first end 1328 to which is secured a handle 1330 and a second end 1332 to which is secured a handle 1334. Extending from the handle 1330 at the first end 1328 of the single pulley cable 1316, the single pulley cable 1316 passes around and the first pulley 1020, the central pulley 1314, and the second pulley 1022 where it ends with the handle at the second end of the single pulley.
Referring now to FIG. 20, in order to facilitate change between the two pulley system and the single pulley system, each of the first pulley 1020, the second pulley 1022 and the central pulley 1314 is provided with a hinged release plate 1410 (not visible in the other figures) allowing for removal of the cables that may be held within the pulley structure. The release plate 1410 is composed of a spring biased hinge member 1412 integrated into the U-shaped frame member 1106, and functions in much the same manner as a carabiner.
When it is time to exercise, the user removes the various functional components, that is, the mounting assembly and the pulley assembly. The abutment member is positioned the exterior side of the door and the strap is slid between the door and the door frame. In particular, the strap is slid between the door and the door frame from the top of the door such that the strap sits upon the upper hinge connecting the door to the door frame.
With the abutment member positioned on the exterior of the door and the strap extending to the interior of the door, the adjustable coupling strap is secured to the strap and the pulley assembly is secured to the adjustable coupling strap. The user then secures the body engaging assembly about his or her torso or waist depending upon the exercise. The pulley cable(s) are then secured to the attachment points of the body engaging assembly. At this point, the user may adjust the adjustable coupling strap to suit the specific exercise he/she plans to perform. In particular, the adjustable coupling strap is adjusted such that the user may use his/her complete weight from the ground up, meaning that he/she will lift his/her whole weight from the ground up, but spreading the load all over his/her body. Thereafter, the user may grip the handles and begin exercising. As a result, the user becomes the weight and can either lean forward or backward while performing various exercises. For example, the present exercising apparatus will allow him/her to do back, squats, shoulders, biceps, triceps etc. with his/her body functioning as the resistance weight.
In the case where he/she desires to do a chest workout, he/she may lean forward with the belt positioned at a comfortable position as shown in FIG. 5. When he/she is doing butterflies or he/she is doing push-ups or shoulders he/she can lean, he/she can go down and come up in one motion using his/her whole body. Because he/she is at an angle, his/her body has to flex all its front muscles to keep him/her straight up. He/she can do back exercises, upper chest exercises, lower chest exercises, sit-ups etc.
While the preferred embodiments have been shown and described, it will be understood that there is no intent to limit the invention by such disclosure, but rather, is intended to cover all modifications and alternate constructions falling within the spirit and scope of the invention.
