Abstract
A weight lifting system wherein shoes of substantially normal fit and construction have additional parts that are designed to attach to and detach from corresponding hardware on weights and weight holding devices, and the additional parts on the shoes will not interfere with walking or other exercises or with the normal function of the shoe. Structural support for the added parts is embedded in the sole of the shoe where it will be unnoticeable by the user. The hardware works quickly and easily and a plurality of different weights is preferred with the net result being that the user can quickly and easily pick up and put down weights with their feet, change the amount of weight, and change weights from foot to foot and, hence, can easily move from one exercise to another, and there is no need to remove the shoes when performing other exercises.
Description
- This application claims the benefit of Provisional Application for Patent No. 61/191,171 filed on Sep. 4, 2008 for “Weight lifting shoes and their weights” from Thomas Jay Zeek.
- The sandals and weights shown in this application are not claimed per se in this application and will be claimed in a later application.
- Not Applicable.
- Not Applicable.
- This invention pertains to weight lifting, specifically to a device that improves the quality and number of exercises that a person can do with their legs. It is a pair of shoes that enable the user to easily pick up and put down weights with their feet and to change weights quickly and they do not interfere with the user's ability to walk or to do other exercises.
- While exercises for the upper body have always been easy to do and plentiful, exercises for the legs have been fewer and much more difficult to coordinate. One of the reasons for this discrepancy is the simple ability of a person to pick up and put down weights with their hands, while no such ability exists for leg exercises.
- This problem is normally addressed by the use of large expensive weight lifting machines. Machines called leg curl and leg extension machines take up a lot of room in the user's house and are only good for a couple of exercises. Other weight lifting machines such as donkey kick machines are more expensive and for most people require a gym membership.
- Many devices have been invented for attaching weights to the user's ankles or feet to increase the number of exercises that can be done. Weighted shoes have been invented which don't hurt the ankles like ankle weights do but they make changing and removing weights difficult, and they hamper walking and other exercises because they remain heavy. U.S. Pat. Nos. 3,517,928 to Shanahan; 3,785,646 to Ruskin; and 6,052,924 to Sabat are examples of such shoes. Methods of adding weights to normal shoes include weights that tie into shoelaces U.S. Pat. No. 5,632,709 to Walsh and a sort of sock that fits over the shoe U.S. Pat. No. 5,728,032 to Glass. In both of those inventions changing weights is time consuming and difficult. All of these inventions are hampered by the limited amount of weight they can employ.
- Closer to the mark have been devices that attach to shoes and which in turn receive various amounts of weight. U.S. Pat. Nos. 2,114,790 to Venables; 2,849,237 to Simithis; 3,343,836 to James; and 6,196,950 to Emick are all examples of such devices. All of these devices are excellent while the user is actually doing the exercise. They all accommodate heavy weight and in one case the ease of changing weights rivals my own invention, but all have the same drawbacks, namely that they interfere with walking and doing other exercises.
- U.S. Pat. Nos. 2,114,790 and 3,343,836 mentioned above both use a very thick sole plate through which a dumbbell passes to add weight. The thickness of the sole plates makes walking awkward and makes other exercises awkward and dangerous as the user could easily “fall off their heels.” They would have to be removed when the user is switching between upper body and lower body exercises. U.S. Pat. No. 2,849,237 uses a thick sole plate as the actual weight and carries with it the same problems as above. U.S. Pat. No. 6,196,950 uses a thin sole plate but changing weights requires the user to fumble with individual weight plates instead of trading out the entire weight or weight holding device. The sole plate is very rigid and flat and not at all conducive to walking.
- U.S. Pat. No. 5,267,927 to Catanzano describes a similar device in which the sole plate is made up of a plurality of weights which can be thin but it is rigid and still awkward and is limited in the amount of weight it can incorporate. U.S. Pat. No. 2,214,052 to Good refers to an exercising boot “preferably made by casting suitable metal in a shaping form or mold.” It is intended to be worn in place of shoes and not over shoes and therefore will be difficult to fit properly. Its rigid design again makes walking and other exercises difficult and dangerous.
- The only invention heretofore that is suitable for heavy weights, allows quick and easy changing of weights, and considers the user's ability to walk and to perform other exercises as well as the user's safety is U.S. Pat. No. 757,983 to Vaile, which discloses a shoe of substantially normal fit and construction with some parts added to accommodate the addition and quick removal of weights, even heavy weights, just like the shoes of my own invention. The mostly normal construction of Vaile's shoe provides comfort, safety, and convenience because it can be worn throughout the user's workout and walking and performing other exercises is still possible, and it provides a solid dependable base for a person who is standing on one foot while exercising with the other foot.
- Vaile's shoe however still carries with it some drawbacks that need to be addressed.
- The first drawback of Vaile's invention is that the structural support for the parts that attach to weights comes in the form of a steel toe section in the front of the shoe. This steel toe completely eliminates all flexibility in the shoe from the ball of the foot forward, which interferes with the ability of the user to bend his or her toes back as would be necessary to for instance run on a treadmill or perform any other exercise that involves standing on the toes of either foot.
- A worse drawback of Vaile's steel toe design is that it prevents the user from pushing their toes down, which may be necessary to keep from falling over forward when the user is lifting heavy weights with their upper body, or doing squats with a barbell on their shoulders.
- Vaile's design also has the drawback of having the weight over the toes of the user's foot. This weight forward design forces the user to exercise their ankle and lower leg muscles and upper leg muscles at the same time. During lateral leg raises for instance the weight will put a twisting force on the user's ankle. Being forced to exercise too many muscles at the same time reduces the effectiveness on the target muscles because the user will get tired before the target muscles have been fully worked.
- Consequently there remains a need for, and it is the object of the current invention to provide a means for a person to quickly and easily pick up and put down heavy weights with their feet that is supremely safe, that does not hurt, does not hamper walking or other exercises, and that allows the user to switch back and forth unimpeded between upper and lower body exercises.
- The current invention is a shoe that is normal in every way except for the addition of a small amount of hardware added for the purpose of attaching to weights, and a small amount of structural support for that hardware embedded in the sole of the shoe where it would be unnoticeable to the user, and weights and weight holding devices with hardware for attaching to the hardware of the shoes. A sturdy heel cup for the shoe is desirable.

FIG. 17 is a top view of the shoe withabbreviated tabs 32 for latching onto the corresponding hardware on weights, and thesturdy heel cup 5 glued onto the outside of the shoe. -
FIG. 18 is a side view of the shoe withfull tabs 6 and theheel cup 5 glued onto the shoe. -
FIGS. 19A and B show an alternate use for thetabs 6 and thetab assembly 116 shown inFIGS. 15A and B wherein thetab assembly 116 is an integral part of a thin and flexible sandal which is to be strapped to the shod foot of the user. - A preferred embodiment of the shoe of the present invention is illustrated in
FIGS. 1A (top view), 1B (side view), 1C (front view), and 1D (perspective view). - The
shoe 40 a is substantially normal in every way but further consists of asturdy heel cup 5 hidden in the heel of the shoe to help to keep theshoe 40 a on the user's foot and a means of tightening theheel cup 5 comfortably around the user's heel, in this case theshoe lace 44.FIG. 18 shows how theshoelace 44 tightens theheel cup 5. A separate means for making the shoe fit the user's foot should be used so that a comfortable fit can be achieved independently from the tightness of theheel cup 5. A hook and loop (Velcro®)shoe strap 42 is used in this example to make the shoe fit comfortably. In the preferred embodiment the strap should describe a Z shape to cover more of the user's foot. The heel cup is shown inFIGS. 16A , 16B, 17, and 18. - The
shoe 40 a further consists of hardware in the form oftabs 6 protruding from the sides of the sole of the shoe which are designed to attach to corresponding hardware that is permanently attached to a weight or a weight holding device such as a special dumbbell, enabling the wearer of the shoe to quickly and easily pick up and put down weights with their feet and to exercise by lifting the weights with their legs. - The
tabs 6 in this case are an integral part of an assembly, in this case atab assembly 116, shown inFIGS. 15A and B consisting of thetabs 6 and amain body 114 preferably comprising a single piece of stiff, sturdy and durable material such as Lexan® polycarbonate from SABIC Innovative Plastics, although any strong and durable material will do, including steel, brass, bronze, fiberglass, or any of several kinds of plastic, provided that said material can be firmly glued and is not brittle, or the tab assembly can be made of several pieces of differing materials. Thetabs 6 also have anotch 24 and aconcavity 22 which enable them to lock onto the hardware that comes with the weights as will be described in detail later. - The
concavity 22 is made by the addition of anordinary metal washer 20 with a notch cut into it but it can also be made by drilling directly into the base material if the tabs are thick enough to accommodate that. - The
tab assembly 116 shown in detail inFIGS. 15A and 15B is passed through a void in the sole of the shoe so that atab 6 protrudes on each side of the shoe and it is glued into that place using a glue that is suitable for the materials chosen for the tab assembly and the sole of the shoe. The tab assembly may further be mechanically fastened to the sole of the shoe using short deep thread screws. Athin rubber laminate 31 is then laminated to the bottom of the entire shoe including the tabs. Thethin rubber laminate 31 can have a thin layer of stretch resistant fabric on its top side for added strength. While themain body 114 of thetab assembly 116 is shown inFIGS. 15A and B as a small and nearly square piece of material it can be made as large as the entire sole of the shoe and the same is true of themain body 114 of thepeg assembly 115 a shown inFIGS. 13A-C and 115 b inFIG. 14 . - In the preferred embodiment the distance between the
notches 24 in thetab assembly 116 would remain constant over several shoe sizes so that the distance between theposts weights 100 and theweight holding devices tab assembly 116 should be plenty even if themain body 114 of the tab assembly changes with every shoe size -
FIG. 2 shows aweight holding device 61 a for use with theshoes 40 a inFIGS. 1A-D , 8A and B, 9 A-C, and 18, and theshoes 40 b inFIG. 17 , and the sandals shown inFIGS. 19A and B. It consists of a 1″diameter bar 62 that is fitted with aplatform 60 and two threadedposts 64 and two wing nuts 66. The approximate dimensions of theplatform 60 are 7″ in width, 2.5″ front to back, and about 0.25″ in thickness, although the thickness is only for strength and can vary according to the material it is made of. The other dimensions of the platform can vary according to the size of theshoe shoe posts 64, but theplatform 60 and the distance between theposts 64 should be limited to a few sizes to match the few sizes of thetab assembly 116 for the reasons listed in paragraph 0044 above. Theplatform 60 also acts as a weight collar and prevents theweights 68 from moving any closer to the user'sshoe - The
bar 62 is of a standard diameter for acceptingnormal barbell weights 68 that are available at most sporting goods stores. -
FIG. 3 shows the weight holding device ofFIG. 2 withnormal barbell weights 68 added to thebars 62. Theweights 68 are held onto thebars 62 with ordinary weight clamps 70 which are also available at most sporting goods stores. The user of this invention would ideally have several of theseweight holding devices 61 a with a different amount of weight on each orseveral weights 100 to completely obviate the need for fumbling with thebarbell weights 68, but the invention is still very valuable for picking up and putting down the weight even if the user only has one. - The shoes and weights of this invention work by the user wearing the
shoes 40 a sliding thetabs 6 under thewing nuts 66 so that thenotches 24 accept the threadedposts 64 and theconcavities 22 are directly under the wing nuts 66. The user then tightens thewing nuts 66 into theconcavities 22 until they are pressing firmly on thetabs 6 and are mostly surrounded by thewashers 20. Theweight 100 orweight holding device 61 a is now locked firmly to theshoe 40 a because thenotches 24 will not allow the threadedposts 64 to move left, right, or back; thewashers 20 reach around thewing nuts 66 and will not allow them to move forward; and thewing nuts 66 will not allow thetabs 6 to come up off of theplatform 60. Additionally, thethin rubber laminate 31 on the bottoms of thetabs 6 is being pressed firmly to theplatform 60 which creates friction preventing any horizontal movement of the shoe on the platform. The user is now free to lift his or her foot and hence the weight in any manner they desire. - After performing the desired number of repetitions of a given exercise the user can quickly and easily remove the weight by loosening the
wing nuts 66 and sliding their foot back off of theplatform 60. The user can then attach the weight to their other foot or attach a different weight to the same foot and continue exercising, or they can leave the weights off and do some upper body exercises with no weights attached to their feet. Theshoes 40 a will not interfere in any way with push ups, sit ups, walking, or almost any other exercise. Thewing nuts 66 never need to be removed from the threadedposts 64, only loosened enough to provide clearance for thewashers 20. -
FIGS. 4 , 5, and 6 show a top view and side views of aweight holding device 61 b that replaces the threadedposts 64 andwing nuts 66 withsmooth posts 90 and locking clamps 94. - The locking clamps 94 work in the same way as Visegrip® locking pliers and use most of the same components. With the locking clamps open as is shown in
FIG. 5 , theshoe 40 a is slid onto theplatform 60 so that thenotches 24 accept the smooth posts 90. With theconcavity 22 mostly encircling thesmooth post 90 and directly under theplunger 82, the user locks the lockingclamp 94 down onto thetab 6 by pushing down on thethumb lever 80 which causes theplunger 82 to go down into theconcavity 22.FIG. 6 shows the lockingclamp 94 in the position for holding down on atab 6. When the user wants to release the clamps they can simply pull up on thethumb lever 80. This weight holding device also works with theshoes 40 b inFIG. 17 . - The locking clamps 94 can be adjusted by means of the threaded
rod 84. With the locking clamps 94 open as inFIG. 5 the user can slide theshoe 40 a into position and depress thethumb lever 80. If the user determines that the clamp is too tight or too loose they can release the clamp and then twist the threadedrod 84 and close the clamp again. When the desired tightness is achieved the user should tighten the lockingnut 86 which will hold the threadedrod 84 in place. Clamps of this type are available from Good Hand Inc., 7141 Paramount Blvd., Pico Rivera, Calif. 90660. -
FIG. 7 shows a cross sectional view of the threadedrod 84 andplunger 82 from the lockingclamp 94. This view shows thehole 96 which accepts thesmooth post 90 when theplunger 82 goes down into theconcavity 22. Thesmooth post 90 prevents theplunger 82 from moving on a horizontal plane and makes sure theplunger 82 goes in exactly the right place. - The
hole 96 has to be deep enough to keep thesmooth post 90 from hitting the top of thehole 96 because that would prevent theplunger 82 from fully descending into theconcavity 22. There should always be some air space above thesmooth post 90 when the lockingclamp 94 is closed. -
FIGS. 8A and 8B show theshoe 40 a with theweight holding device 61 a attached in the proper way. -
FIGS. 9A , 9B, and 9C show a person using this invention to perform various exercises. -
FIG. 10 shows aspecial weight 100 designed specifically for use with theshoes curved bottom 102 to facilitate walking a few steps to or from a chair and it can be made of plastic filled with sand, concrete, lead, etc. or it can be made of a single piece of cast iron. It can be made in various sizes. -
FIGS. 11A and 11B show a front view and a perspective view of a different embodiment of this invention designed for use with theweight holding device 61 c shown inFIG. 12 . Thetab assembly 116 is replaced by apeg assembly 115 a shown inFIGS. 13A-C , wherein thetabs 6 are replaced bypegs 110 andspacers 111. -
FIG. 12 shows an end view of aweight holding device 61 c which is designed for use with theshoes 40 c shown inFIGS. 11A and 11B . The user wearing theshoes 40 c engages theweight holding device 61 c by stepping down on it so that thepegs 110 are forced through thelatches 112. Thelatches 112 have a spring and close automatically to hold thepegs 110 in place. Thespacers 111 contact the sides of thelatch mechanisms 131 to prevent any lateral movement by theshoe 40 c. The distance filled by thespacers 111 should remain constant over several shoe sizes as is shown inFIGS. 13A-C andFIG. 14 for the reasons discussed in paragraph 0044 above. When the user of this embodiment of the invention wants to release theshoe 40 c from thelatch mechanisms 131 they only have to depress the latch levers 113 and thelatches 112 will move out of the way. -
FIGS. 13A-C show a top, side, and front view of an assembly, in this case apeg assembly 115 a, used to make theshoes 40 c of this invention. It consists of amain body 114, pegs 110, andspacers 111. This is an alternative to thetab assembly 116 described in detail in paragraphs 0041-0043 above. It employs the samemain body 114 and the considerations for the choice of materials are the same as for that embodiment, except that thepegs 110 should be made of steel. - The
peg assembly 115 a is also built into theshoe 40 c in basically the same manner as thetab assembly 116. Thepeg assembly 115 a is passed through a void in the sole of the shoe so that a peg and spacer protrude from each side. Thepeg assembly 115 a is glued into that place using a suitable glue and like thetab assembly 116 may be further secured to the shoe sole with short deep thread screws. Themain body 114 is again shown as a small and nearly square piece of material but as in thetab assembly 116 described in paragraph 0043 above, the main body can be as large as the entire footprint of the shoe. - The difference in construction for
shoes 40 c using thepeg assembly 115 a compared toshoes 40 a using thetab assembly 116 rests in the fact that thepegs 110 are higher than thetabs 6 and therefore thepeg assembly 115 a should not be in direct contact with the thin rubber laminate on the bottom of the shoe but should be placed higher in the sole of the shoe. - If the
main body 114 of thepeg assembly 115 a is small as shown inFIGS. 13A-C , a layer of stretch resistant fabric can be added into the sole of theshoe 40 c for added strength, but a larger main body is preferable and the same is true for thetab assembly 116. -
FIG. 14 shows a top view of apeg assembly 115 b which is the same in every way as thepeg assembly 115 a inFIG. 13A except that themain body 114 is smaller for a smaller shoe size while thepegs 110 andspacers 111 remain the same size and cover the same distance. -
FIGS. 15A and 15B are a top and side view of thetab assembly 116 described in detail in paragraphs 0041 through 0043 above. -
FIGS. 16A and 16B are a top and side view of theheel cup 5 hidden in theshoe 40 a inFIGS. 1A-D and theshoe 40 c inFIGS. 11A and 11B .FIGS. 17 and 18 show shoes with thissame heel cup 5 glued to the outside of the shoe andFIG. 18 further shows how theshoelace 44 is used to tighten theheel cup 5 without affecting the overall fit of the shoe. It should also be noted that the arms of theheel cup 134 will act as a draw string around the top of the user's foot in addition to the grip that theheel cup 5 will create on the user's heel. The shoes may be further engineered to enhance this feature. -
FIG. 17 shows a top view of ashoe 40 b that uses a third version of hardware for attaching to weights. Thetab 6 inFIGS. 1A to 1D is replaced by anabbreviated tab 32 which has an abbreviatedwasher 34 and anabbreviated concavity 36 and anabbreviated notch 38. This can all be made by simply sawing the ends off of thetab assembly 116 shown inFIGS. 15A and 15B .FIG. 17 also shows theheel cup 5 glued to the outside of theshoe 40 b. -
FIG. 18 shows a side view of the shoe inFIGS. 1A to 1D but with theheel cup 5 on the outside of the shoe. -
FIGS. 19A and 19B show a thin and flexible sandal which uses thetab assembly 116 as an integral part of its main body with athin rubber laminate 30 and a non slipupper surface 28 as well as a heel cup and various straps to secure it to the shod foot of the user. Its thinness and flexibility make it safe and easy to use and to wear. It is shown as an alternative use for thetabs 6, thetab assembly 116, or any other such shoe part or assembly. - Accordingly the reader will see that the shoes and weights and the various hardware of this invention will provide a method of lower body exercises that is effective, safe, easy to operate, low cost, and can be used and kept easily in a small room or apartment.
- Although the description above contains many specificities, exact descriptions of the hardware used to attach the weights to the shoes may be innumerable, and examples shown should not be construed as limiting the scope of this invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. Parts that attach to corresponding hardware on the weights may be recessed into the sides or the bottom of the shoe's sole. Additionally, the shoes of this invention can be boots, loafers using the disclosed heel cup, high tops, or any other kind of shoe that is found to work.
