Abstract

This invention relates to a jump rope structure that increases the number of rotations. Specifically, it refers to a structure that accelerates the rotation speed of the jump rope. The jump rope consists of two handles and a rope body. Handles are attached to both ends of the rope body, allowing it to be used as a jump rope. The middle section of the rope body has a smaller diameter than the ends. When the user uses the same wrist and arm strength to rotate the rope, the reduced mass distribution in the middle section decreases the moment of inertia, thus increasing the number of rotations in the same number of seconds. This is truly an advanced piece of exercise equipment.

Description

Jump rope structure that can increase the number of loops

This creation relates to a jump rope structure that increases the number of rotations. It utilizes a rope that tapers in the middle to effectively reduce wind resistance and inertia during rotation, thereby increasing the number of rotations in the same amount of time.

Note that a traditional jump rope 1 consists of handles 10 at both ends and a rope body 11. Please refer to Figure 1, which is a schematic diagram of a familiar jump rope. The rope body 11 has a uniform diameter. When the user swings, the number of rotations of the rope body 11 is limited due to its weight and wind resistance. To increase the number of rotations, it is often necessary to increase the swing speed, causing strain on the user's wrists and arms. This design is not suitable for long-term practice or professional competition.

In jump rope competitions, please refer to Figure 1. The number of loops (11) the athlete performs directly impacts their results. However, athletes have maximum load limits on their wrists and arms. Therefore, increasing the number of loops can be achieved by modifying the structure of the rope (11). Reducing the diameter of the middle section of the rope (11) not only lightens the rope's weight but also reduces air resistance, allowing users to effectively increase the number of loops under the same physical conditions and achieve better results.

The creator, specializing in lifestyle and entertainment products, understands that while traditional jump ropes allow for smooth competition and freestyle maneuvers, they cannot significantly increase rotational speed. This creation involves reducing the rope's diameter, thereby decreasing air resistance and weight inertia during rotation. This allows the rope to rotate more times in the same number of seconds, making it an excellent and innovative jump rope structure.

This invention relates to a jump rope structure that increases the number of loops. The rope is thinner in the middle section than at the ends, thereby reducing air resistance and weight in the middle section during rotation.

It mainly consists of two handles and a rope. Handles are attached to both ends of the rope, allowing it to be used as a jump rope. The middle section of the rope is smaller in diameter than the two ends. This middle section refers to approximately one-third of the rope's length, and its diameter is reduced by 10% to 50% compared to the ends. This reduces the mass distribution during rotation in this middle section, thereby lowering the moment of inertia and increasing the number of rotations in the same number of seconds.

When in use, the reduced mass distribution in the middle section of the rope, along with decreased wind resistance, allows the user to increase rotation speed with the same force, achieving more rotations in the same number of seconds. This effectively helps competitors break through their previous rotation limits and significantly improve their rotation count.

The rope's midsection diameter is reduced by using lightweight materials or a thinning process; this reduced midsection structure features a smooth transition zone to prevent breakage or discomfort during use; the rope's ends maintain their original diameter to ensure stability when held by the user and when the rope's ends impact the ground.

The rope features markings printed evenly from its center point outwards. These markings allow users to adjust the rope length according to their height, using the center point as a reference to evenly trim the rope's edges. This helps maintain the rope's center of gravity, ensuring proper and rapid rotation.

Therefore, this invention, by improving the structure of the middle section of the rope, can increase the number of jumps in the same number of seconds without increasing the user's burden, effectively achieving the training results of jump rope training. It is truly a novel innovation in jump rope structure.

The first diagram is a schematic diagram for learning how to jump rope.

The second image is a schematic diagram of this jump rope creation.

Figure 3 is a 3D diagram used in this jump rope creation.

Figure 4 is a schematic diagram of the annotation lines for this work.

First, please refer to Figure 2, a schematic diagram of this jump rope. It mainly consists of two handles 20 and a rope body 21. The handles 20 are connected to both ends of the rope body 21, allowing it to be used as a jump rope 2. The middle section 22 of this jump rope 2 has a smaller diameter than the two ends. This middle section 22 refers to approximately one-third of the length of the rope body 21. The diameter reduction is 10% to 50% compared to the two ends, which reduces the mass distribution in the middle section 22 during rotation, thereby reducing the moment of inertia and increasing the number of rotations in the same number of seconds.

When using this jump rope, please refer to Figure 3, which shows a 3D diagram of its application. Due to the reduced mass distribution in the middle section 22 of the rope, and the reduced wind resistance, the user 3 can increase their rotation speed with the same force, achieving more rotations in the same number of seconds. This effectively helps competitors break through their previous rotation limits and significantly improve their jump count.

Referring again to Figure 3, the diameter of the middle section 22 of the rope is reduced by using lightweight materials or a thinning process to form the rope 21. The reduced diameter structure of the middle section 22 has a smooth transition area to prevent breakage or discomfort during use. The two ends of the rope 21 maintain their original diameter to ensure stability when the user holds the rope with three hands and when the ends of the rope 21 impact the ground.

Next, please refer to Figure 4. A marking line 220 is provided in the middle section 22 of the rope. This marking line 220 is evenly printed from the center point of the middle section 22 towards both ends. When the user 3 adjusts the length of the rope 21 according to their height (not shown in the figure), they can use the center point of the marking line 220 as a reference to evenly cut the two ends of the rope 21, keeping the middle section 22 in a centered position and ensuring that the center of gravity does not shift, thus achieving accurate and rapid rotation.

Therefore, referring back to Figure 3, the middle section 22 of the rope in this creation is designed to be thinner than the two ends, thus achieving the following technical effects:

1. Reducing Moment of Inertia: Since the middle section 22 of the rope is distributed on the outer periphery during rotation, a larger mass will significantly increase rotational inertia, requiring the user 3 to apply greater force to maintain high-speed rotation. This invention reduces the diameter and mass of the middle section 22 of the rope, significantly decreasing the moment of inertia and achieving a faster rotational speed with the same force.

2. Reduced Air Resistance: During high-speed swinging, the rope 21 is affected by air friction and resistance. The narrowed diameter design of the middle section 22 of the rope effectively reduces the cross-sectional area, thereby reducing wind resistance and allowing the rope 21 to flow smoothly through the air without excessive energy consumption.

3. Improved Energy Efficiency: By reducing inertia and wind resistance, this design allows users to achieve more rotations in the same amount of time and with the same wrist swing amplitude, thus improving exercise efficiency and training effectiveness.

4. Suitable for professional competition and training: Because it reduces strain on the wrists and arms, this design is suitable for long periods of practice and can improve jump count performance in competitive rope skipping, possessing the advantages of commercially available sports equipment.

In conclusion, this invention, by improving the structure of the middle section of the rope, can increase the number of jumps within the same number of seconds without increasing the user's burden, effectively achieving the training results of jump rope. It possesses industrial innovation and progress, and therefore meets the requirements for a utility model patent; thus, a patent application is hereby filed in accordance with the law.
