Description

[Detailed description of the invention]

[Technical Field of the Invention] The present invention relates to the improvement of exercise equipment, and more particularly, it is attached to the foot 1, ankle or leg so that the user can jog, walk, run or dance at the same speed. This invention relates to a lower limb training exercise device (weighting device) that requires applying more force than usual in order to exercise, and therefore trains more muscles within a predetermined time. [Technical background of the invention and its problems] Weighting devices of the type attached to the ankle (gaiter type) or the type attached to the leg are located above the ankle where the leg starts, so they do not have any effect on the leg. Trains only the thigh muscles without producing any useful benefits. Additionally, ankle weight devices tend to cause abrasions on the ankles as the weights move up and down during running. Additionally, these weighting devices require unique laces and cannot utilize existing shoe laces. If the weighting device is used in the foot beyond the ankle, ie distal (beyond the toes), the weight applies the load through the ankle to the leg and thigh muscles. Therefore, an adjustment device that applies weight to the foot rather than the ankle or leg is highly desirable. Of course, increasing the weight of the foot increases the load on the legs and thighs. U.S. Pat. No. 3,114,982 discloses a removable weight for an athletic shoe, but this installation requires a special shoe and also requires a device located inside the shoe. In order to prevent the parts from coming into contact with each other during running, the outer part of each shoe is designed to be fixed. This creates a weight imbalance between the parts of the foot. Because the weight is fixed, it is not possible to increase the load without increasing the compression of the key.The further the weight is placed distal to the foot, the more load is applied to the leg and thigh. 1- [Objective of the Invention] The main object of the present invention is to add weight to the foot distal to the ankle and adjust this weight to compress the leg and thigh without excessive compression of the foot surface. Another object of the present invention is to manufacture a lower limb training exercise device that can be used with any ordinary lace-up shoe. [Summary of the Invention] The lower!!&training exercise equipment according to the present invention has two hollow bags of the same shape, suitable weights are inserted into these bags, and weights are placed above the mouths of the bags. It is accommodated inside the bag by folding in the adhesive flap with the foil layer.One side of the bag (J) has a tab, which corresponds to the spacing of the lace holes of athletic shoes. A strap with two complementary removable adhesive bands in the form of a flat fastener on its outer surface is opened on the opposite side of one bag, and a ring is secured on the opposite side of the other bag. These bags must be placed symmetrically on each side of any regular lace-up shoe, with the holes in the bag aligned with the lace holes.Then the bags exit through the holes on the first side of the shoe. The shoelace section is then laced in a normal bowknot, except that the shoelace section passes through the corresponding alignment hole in this first side bag and then into the next tallest hole on the opposite side of the shoe. When it comes out, it passes through the corresponding hole in the bag on the second side, then it is folded back and passed through the high shoelace hole on the first side.
Continued in this manner 3. The strap is looped around the back of the shoe, threaded through the ring, folded over to take up the slack, and then secured by crimping complementary hook/pile adhesive bands together. fixed in position to hold each shoe and its weight bag in place. [Embodiments of the Invention] The present invention will be described below with reference to embodiments shown in the drawings. To explain Figures 1 to 4, reference numeral 10
shows the exercise device (adjustable weight device) of the present invention, with its strap 22 in the fastened position. This exercise equipment consists of two identical bags made of woven fabric or other suitable flexible material.

[Has 2. The bag has a recess 14 and a fold-in flap 15. Below each flap is sewn or otherwise secured a removable adhesive band 16 of the flat 7 snap-on type commercially available under 01llTL1 trademark Velcro. A corresponding adhesive band 17 of the same type is also sewn or otherwise secured to the top of the bag 12. 'Corresponding 1' means that one band has a plurality of fiber hooks and the other band contains a plurality of pile elements, so that when the corresponding surfaces of these bands are crimped, they adhere to each other 1- It means that. However, these adhesive surfaces can be separated by applying appropriate force. As shown in FIG. 4, the desired weight assembly 13 is inserted into each recess 14σ), its upper pressure flap 15 is folded in, the corresponding adhesive band tightly seals the recess, and the weight assembly is inserted. [3] Prevents the concave part from coming out. You can pull open the flap to remove the weight or replace it with a lighter or heavier weight. In this embodiment, the weight assembly 13 consists of a plastic package containing sealed lead shot, but with the exception of the pan cage, a lead casting of the desired shape and mass can be inserted directly into the recess. On the left side σ of FIG. 4, a flexible tab 18 made of a suitable fabric is sewn onto one side of the bag 12, and on the right side bag 1.2, a flexible tab 18 is attached to each shoe 11, as shown in FIG. To make it easier to knit the cotton bag, a tab is sewn and attached to the opposite side. Each tab 18 has the same spacing as the shoelace holes of the athletic shoes shown in FIGS.

You can reverse the cloth shoe and left shoe as shown in N4. The strap 22 is placed open or closed so that there is an appropriate amount of slack between the strap and the rear part of the shoe 11,
One bag 12 is placed on one side of the shoe 11, and the other bag is placed directly opposite the other side of the shoe, and the holes 19a to 19h in the cups of these bags correspond to the shoelace holes on the corresponding side of the shoe. and roughly aligned. Next, knit the sports equipment 10 onto the shoes 11 shown in FIG. Shoelace part 2 from the shoelace hole on the inner flap of the shoe
7 comes out, this part 27 is inserted into the leftmost hole 19a of the inner bag 12 of the cloth shoe, and then this shoelace end 27 is inserted into the lace hole 29 of the outer flap of the shoe. Next, the cloth shoe is passed through the tab hole 19f of the outer bag 12, and then the shoe υ is passed through the hole 30, the tab hole 190, etc. The other end of the shoelace 31 is likewise passed alternately through the shoelace hole and the tab hole of the bag. Figures 1 through 3 show the bag in the position furthest from the toe with respect to the lace hole. However, the bag's tab hole 1

4 and 35 respectively, it is clear that the bag can be moved towards the tip of the shoe (towards the toe). By aligning the tab hole with the front lace hole of the athletic shoe, the load applied to the leg and thigh is increased.This back-and-forth movement of the rapid-fire device 10 is combined with changes in the load inside the bag. By doing this, a certain adjustment range is obtained, from which the user can select according to the purpose. In Figures 1 to 3, the bag cup J8 is the shoe θ. The solid line shows the bag approximately parallel to the flap edge 39. However, depending on the weaving force of the string, the bag can be tilted as shown by the chain line 40 in FIG. This is an additional adjustment method depending on your preference. Figure 5 shows the inner part of each foot (ijll vc
