FIELD OF THE INVENTION
The present invention relates to resistance training exercise apparatus. More particularly, the present invention relates to apparatus and methods for converting an exercise treadmill for resistance training strength workouts.
BACKGROUND
Home exercise machines are widespread. Some machines provide aerobic exercise, such as treadmills and other “cardio machines.” Some machines provide strength training such as weight machines and resistance machines using elastic straps or resistance gears. Examples include such suppliers as BOWFLEXTM and NAUTILUSTM. These machines have drawbacks, however. These machines are essentially single purpose—they provide either a cardio workout or a strength workout, but can't provide for both in the same footprint. Most people have limited space in their home or office to store and use exercise equipment and don't have room for both a cardio machine and a strength machine. These machines can also be quite expensive. The cost of purchasing a stand-alone cardio machine and a stand-alone strength machine can be prohibitive for many.
The ability to squeeze more productivity out of the same old treadmill machine is motivating to fitness buffs, and this positive spirit can translate into better workouts and improved health. The world benefits. Spending extra money for a second exercise machine, and trying to cram a second machine into a space that was not big enough for the original treadmill to begin with, makes people sad. They become frustrated and cease working out altogether, reverting to a life of eating chips and watching TV. The world is harmed.
Many people who already own treadmills would benefit from additional strength exercises, but the space taken by treadmills (which include motors, displays, support rails, and oversized footprints for safety reasons) precludes purchasing another exercise machine. Moreover, an effective strength training machine should provide for multiple positions and multiple angles of resistance in order to work different muscle groups. An effective strength training machine should provide for exercises in the supine and standing positions. Importantly, persons who have already purchased an expensive, space-consuming treadmill would benefit greatly from being able to add strength training devices to their existing machine rather than have to obtain a new combination machine.
Thus, there is a need for a method and apparatus to convert an existing exercise treadmill into a strength training machine without negating its ability to operate as a treadmill. Such a machine should also be able to accommodate
A number of devices have provided treadmills and resistance exercises, but lack the ability to convert an operating treadmill for resistance training, with the ability to perform exercises in a sitting or supine position as well as while walking on the treadmill. Presently known art attempts to address this problem, but has not completely solved the problem. The following represents a list of known related art:

Handle second part mounting hole 1108 and friction disks 1104 and 1106 align with joint plate center mounting holes 1100 and 1102 to receive joint axel bolt 1116. Preferably joint axel bolt 1116 includes a knurled or petalled handle grip for ease of use. An index locking pin 1042 is provided to engage joint index holes 1096 and 1098 with handle second part index hole 1110, thereby allowing handle second part 1088 to be locked in a desired angular orientation to handle first part 1082. Alternatively, with index pin 1042 removed, handle second part 1088 may be rotated about joint 1090 for exercise, with friction resistance provided by friction disks 1104 and 1106. Preferably friction disks 1104 and 1106 are made from plastic material such as nylon for ease of manufacture and minimal expense, as they will wear over time, but any suitable material may be used.
One or more resistance straps 1040 are provided for connecting between mounting bracket 1020 and translation member 1050. Resistance strap 1040 connects at a first end 1044 to mounting bracket 1020 via anchor 1038 and at a second end 1046 to translation member 1050 using a locking pin 1042 through translation member index holes 1060 and 1062. Resistance strap 1040 is preferably made from a strong stretchable material such as butyl rubber, but other stretchable materials such as silicone rubber or other suitable materials could be used. Additionally, flexible straps 1120 may be attached to translation member 1050 using a locking pin through index holes 1060 and 1062 in order to increase the range of exercises available. In the disclosed embodiment flexible straps 1120 are bungee cords or surgical tubing.
Referring to FIGS. 6-9, in operation the second embodiment, a user begins by assembling and mounting the conversion apparatus to a treadmill. Assembly involves inserting axel bolt 1048 and anchor 1038 through connection point 1034 and hole 1039 (if not permanently mounted), respectively, then mounting the attachments 1010a and 1010b around respective treadmill vertical support columns VR and VL by sandwiching first and second mounting bracket parts 1022 and 1024 around each of vertical support columns VR and VL, tightening adjustable securing straps 1036 to hold them tightly, and threading locking handles 1028 through slotted holes 1026 to lock first and second parts 1022 and 1024 in place. Articulated handle 1080 is inserted into translation member 1050 and aligned at a desired angle, and locking pins 1042 are inserted through index holes 1060, 1062, 1084 and 1085. Translation member 1050, with handle 1080 mounted therein, is attached to connection point 1034 using axel bolt 1048 and locking nut and washer 1051. Locking nut and washer 1051 lock to prevent backing off axel bolt 1048, but do not lock translation member 1050 from rotation. Translation member 1050 is free to rotate about axel bolt 1048.
Resistance strap 1040 is connected at first end 1044 using anchor 1038, and at a second end 1046 to translation member 1050 using a locking pin 1042. Resistance strap 1040 may be connected at any of the indexing holes 1060 and 1062, thereby allowing a user to accommodate straps of differing length. The user may also selectively adjust the angle of handle 1080 by selecting different index holes 1060 and 1062, to accommodate different user heights or different ranges of motion. Use of additional resistance straps 1040 allows incremental increase in resistance and therefore the intensity of exercises. Attaching resistance strips 1040 to translation member 1050 at a radial distance from axel bolt 1048 provides a smooth, essentially linear resistance profile. Resistance strap 1040 could also be attached to handle 1080 and function adequately. A plurality of resistance straps 1040 may be connected between anchor 1038 and opposing sides of translation member 1050 to provide resistance in both directions.
Articulated handle joint 1090 allows a user to lock handle 1080 at a selected angle in order to utilize resistance straps 1040 for exercise, or to unlock handle joint handle joint 1090 and use handle 1080 for resistance exercising. Resistance of handle joint 1090 to rotation is adjustable by adjusting the tightness of joint axel bolt 1116—i.e. tightening joint axel bolt 1116 compresses joint plates 1092 and 1094 against friction disks 1104 and 1106, thereby increasing resistance, while loosening joint axel bolt 1116 reduces resistance.
A user may utilize articulated bench 200, shown in FIG. 4, placed over treadway T in order to perform bench presses, shoulder presses, and other traditional strength exercises from a supine, prone, or sitting position. Alternatively, a user could lay a pad directly on treadway T and lie or sit on the pad to perform exercises.
Referring to FIG. 7, the nature of movement of the translation member 1050 and articulated handle joint 1090 are shown by hidden lines. Varying the angle of handle 1080, and/or the connection point of resistance strap 1040 to translation member 1050, and/or the model of resistance strap 1040, and/or the angle of joint 1090, and/or the rotational resistance of joint 1090, allows the treadmill resistance training apparatus to accommodate a wide range of user heights, abilities, and exercises of various ranges of motion and resistance profiles.
The treadmill resistance training apparatus 1000 is easily removable by reversing the attachment steps described above. A user may choose to simply leave the resistance training apparatus attached, as the apparatus does not interfere with the normal operation of the treadmill.
