[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a training loader for enhancing leg strength and waist strength used in a running competition from short-distance running to marathon in track and field.

[0002]

[Prior art]

 In athletics, it is essential to increase leg strength and waist strength in order to increase running speed, and for this reason, running is repeatedly practiced repeatedly. In addition, it has been attempted to attach a string to the waist, attach an automobile tire to the tip of the string, install the tire on the ground, and add a load to the human body by running to increase leg strength and waist strength.

In the training that gives a load to the human body by the gravity of the tire, the leg strength and the waist strength are strengthened, but the weighting direction between the tire on the ground and the string attached to the waist is downward. However, since the opposing force bends excessively around the waist of the human body and becomes a forward leaning posture, it may not be a rational training method unlike the optimal running posture.

Further, there is also known a training tool in which a plurality of strings are attached to the periphery of the seat, and a parachute having these ends assembled with a locking tool is locked to a belt provided on the waist of the human body.

In the above parachute-type training equipment, the lift of the parachute is applied during traveling, the traveling due to excessive forward leaning posture is improved, and it is more rational than the training method of dragging tires, May expand laterally, and when practicing driving on roads in urban areas, for example, the parachute may touch or hit other passersby, causing annoyance. Therefore, it is not suitable for training in any place where there are passersby. In addition, the parachute has the drawbacks that the work of sewing and integrating the fabrics having a plurality of curved surfaces is troublesome, the cost cost is high, and the productivity is low.

[0008]

[Embodiment of the invention]

 An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the back portion 2 of the training shirt 1 has a first portion that is approximately 5 to 15% longer than the length of the training shirt 1 in the horizontal direction and has a shoulder length in the horizontal direction. A synthetic fiber cloth 3 is provided. The upper side 4 and the lower side 5 of the synthetic fiber cloth 3 are sewn together with a sewing machine or the like, and the left side 6 and the right side 7 are separated from the training shirt 1 with a gap. For example, when the size of the training shirt 1 is M, it is appropriate that the first synthetic fiber cloth 3 has a length of 50 cm in the lateral direction and 75 cm in the longitudinal direction. The synthetic fiber cloth 3 is preferably a synthetic fiber such as polyester or nylon, which is woven with a proper weave such as a plain weave or a twill weave, with a density of 40 to 60 filaments / cm, which is a filament yarn made of long fibers having a denier of 30 to 50. In addition, it is more preferable to color in order to improve the distinguishability.

A ring-shaped fastener 8 is attached to an appropriate portion of the peripheral portion of the first synthetic fiber cloth 3. As shown in FIG. 1, there are three fasteners 8 on the upper side 4 of the synthetic fiber cloth 3, one on the lower side 5 slightly above the center, and two on the left side 6 and the right side 7. It is suitable to be installed in place. Alternatively, the synthetic fiber cloth 3 may be formed into a bag shape, and the inside may be filled with air.

As shown in FIG. 2, separately from the first synthetic fiber cloth, the lateral direction has a width of 1.5 to 2 times the shoulder width of the training shirt 1, and the longitudinal direction is the lateral width. The second synthetic fiber cloth 10 having substantially the same length as the direction is provided. The synthetic fiber cloth 10 has a circular hole 11 at the center. For example, when the size of the training shirt 1 is M size, it is preferable that the second synthetic fiber cloth 10 has a length of 120 cm in the longitudinal and lateral directions and the circular diameter of the hole 11 is about 10 cm. The synthetic fiber cloth 10 is also preferably made of synthetic fibers such as polyester and nylon, which are woven with filaments of 30 to 50 denier filaments at a density of 40 to 60 yarns / cm in a proper weave such as plain weave or twill weave. . Moreover, in order to improve the distinctiveness, it is preferable to color. The color may be different from that of the first synthetic fiber cloth 3.

On the peripheral portion of the second synthetic fiber cloth 10, at appropriate places corresponding to the fasteners 8 attached to the peripheral portion of the first synthetic fiber cloth 3, the string 12 and the tip of the string 12 are attached. A lock 13 is provided. As shown in FIG. 2, it is preferable that the string 12 be attached to each of the corner portions of the synthetic fiber cloth 10 at one place, and each of the upper side portion 14, the lower side portion 15, the left side portion 16, and the right side portion 17 to be attached at one place. Is. For example, when the size of the training shirt 1 is M size, the length of the string 12 is preferably 20 cm to 30 cm. A string 18 may be provided in the circular hole 11 so as to cross the center thereof. The locking tool 13 may have any shape and structure as long as it locks the fastener 8 attached to the peripheral edge of the first synthetic fiber cloth 3. For example, the one shown in FIG. 2 is made of an elastic body that locks the ring-shaped fastener 8 and has a hook shape having an insertion opening and detachable. The synthetic fiber cloth 10 may be formed in a bag shape and the inside thereof may be filled with air.

When using the above-described load tool for leg and waist training, a training shirt is worn, and a portion corresponding to the fastener 8 attached to the peripheral portion of the first synthetic fiber cloth 3 is The locking tool 13 provided at the tip of the string 12 attached to the peripheral portion of the second synthetic fiber cloth 10 is locked. When running in this state, as shown in FIG. 3, air enters between the first synthetic fiber cloth 3 and the second synthetic fiber cloth 10, and the second synthetic fiber cloth 10 is entrapped by air resistance. Levitate backwards. Further, since the first synthetic fiber cloth 3 attached to the back of the training shirt has air between the back and the first synthetic fiber cloth 3 and floats backward due to air resistance, the second synthetic fiber cloth The cloth 10 largely encircles and floats upward and rearward due to air resistance. The circular hole 11 provided in the second synthetic fiber cloth 10 moderately reduces the air resistance of the second synthetic fiber cloth 10. Then, since the runner using the training load travels against the air resistance of the load, the training effect is improved.

In this use, when the length of the first synthetic fiber cloth 3 in the longitudinal direction is 5% or less than the length of the training shirt 1, the back part and the first synthetic fiber cloth 3 are worn during running. Since no air enters between the fiber cloth 3 and the fiber cloth 3, there is almost no levitation force to the rear due to air resistance. If the length of the first synthetic fiber cloth 3 in the longitudinal direction is 15% or more than the length of the training shirt 1, the rearward levitation force of the first synthetic fiber cloth 3 due to air resistance is too large. , The human body of the rider is shaken and the driver cannot drive stably.

When the dimension of the second synthetic fiber cloth 10 is less than or equal to 1.5 of the shoulder width length of the training shirt 1, air is generated between the first synthetic fiber cloth 3 and the second synthetic fiber cloth 10. Since it is hard to enter, the rearward floating force due to the air resistance of the second synthetic fiber fabric 10 is small, and the training effect is small. Further, when the dimension of the second synthetic fiber cloth 10 is at least twice the shoulder width of the training shirt 1, air enters between the first synthetic fiber cloth 3 and the second synthetic fiber cloth 10. Since the levitation force to the rear due to the air resistance of the second synthetic fiber fabric 10 is too large, the air resistance is excessive and the runner is easily tired. Further, if the length of the cord is longer than 30 cm, air easily escapes and the second synthetic fiber fabric 10 causes a turbulent flow due to the air resistance, which makes the second synthetic fiber fabric 10 unstable and vibrates the human body. To do. If the length of the cord is too shorter than 20 cm, the rearward levitating force of the second synthetic fiber fabric 10 is small and the training effect is not obtained.

[0015]

[Effect of the invention]

 Since the present invention is configured as described above, when the user wears this and runs, a levitation force to the rear is generated due to the air resistance between the first synthetic fiber cloth and the second synthetic fiber cloth, and the leg strength and waist are reduced. Because you have to run with a lot of strength, you can increase the speed of running and practice running while changing the size of the pitch slide between your legs, and you can also improve your endurance. Furthermore, it is possible to drive while correcting the forward leaning posture.

Since the first synthetic fiber cloth and the second synthetic fiber cloth are lightweight and can be stored, they are easy to carry and have a small folding storage volume, so they are not bulky. Also, when practicing on a road such as an urban area, it does not cause inconvenience by touching or hitting other passersby, so it is suitable for training in any place where there are passersby.
