Jump rope grip with rotating function

Abstract

The jump rope user needs to bend his / her wrists in a direction that opens them out to the left and right, and the present invention provides a grip that allows the user to adopt a natural posture when jumping rope. [Solution] This is a skipping rope grip, and has a structure in which the part 3 to which the skipping rope is attached can be transformed into an L-shape by a part 4 that can rotate up to a maximum of 90 degrees. The rotating part can be rotated in 10-degree increments up to a maximum angle of 90 degrees.

Description

[Technical Field]

[0001] The present invention relates to sports or exercise equipment, and more particularly to skipping ropes. [Background technology]

[0002] Previously, known skipping ropes consisted of a string and two grips attached to each end of the string. For example, to prevent twisting of the rope during use, some models have a jump rope attached to a rotatable shaft at the end of the grip. Other models have a mechanism built into the grip to adjust the rope's length. Furthermore, to prevent twisting due to high-speed rotation of the skipping rope, such as in double jumps, a proposed structure has been proposed in which the spherical head of a rotating body with a spherical head and arm-like claws is connected to the grip body via a holding part, and the arm-like claws connect to the rope. In this structure, the spherical head can freely move in a conical and rotational motion relative to the holding part, allowing the string to rotate smoothly.

[0005] Previous skipping rope grips either had a rotating rope attached to the grip, or had a mechanism for adjusting the length of the rope, or they only reduced friction when skipping, but none of them took into consideration the arms and wrists holding the grip. In other words, with conventional technology, the skipper had to bend his or her wrists to the left and right, making it difficult to maintain a natural posture when skipping. This caused a problem of heavy strain on the wrists. [Means for solving the problem]

[0006] The inventor of this invention has been working diligently to solve the above problems and has completed this invention. That is, this invention relates to a jump rope grip that has a structure where the part where the jump rope is attached can rotate up to 90 degrees and deform into an L-shape.

[0007] The grip shape of this invention is characterized in that the ratio of the length of the rotating part of the grip that transforms into an L-shape to the non-rotating part is in the range of 5.3cm to 5.5cm. The ratio of the diameter of the rotating part of the grip that transforms into an L-shape to the non-rotating part is in the range of 8.5 to 8.7. The rotating part of the grip that transforms into an L-shape rotates in 10-degree increments up to 90 degrees. [Effects of the Invention]

[0008] By using a jump rope equipped with the grips of this invention on both ends, users can jump in a more comfortable position for their arms and wrists. Furthermore, the grips of this invention have a rotating adjustment mechanism, allowing for stepwise rotation from a traditional straight jump rope grip to an L-shaped grip with a maximum rotation angle of 90 degrees, allowing users to more easily adapt to this new style of jumping. [Brief explanation of the drawings]

[0010] Hereinafter, an embodiment of the present invention will be described. (1) The jump rope grip of the present invention The jump rope grip of this invention is equipped with a rotation function. This rotation function allows for step-adjustment of the angle, allowing for rotation in 10-degree increments up to a maximum angle of 90 degrees. This step-adjustment can be fixed inside the grip, preventing the rotation angle from changing when using the jump rope equipped with this grip. The means for fixing this is not particularly limited in this invention, but either an internal gear or an internal stopper is suitable. Furthermore, when rotated to the maximum angle of 90 degrees, for example, the grip of this invention transforms into an L-shape.

[0011] The grip material of the present invention is not particularly limited as long as it is easy to grip when in use, but for example, plastic is preferable, and polypropylene is particularly suitable. The grip surface may also be treated with a non-slip coating, such as a rubber or sponge coating. Furthermore, the present invention may be combined with a shape that fits the gripping hand, such as a grip with a recessed shape.

[0012] (2) The strain on the joints when using the grip of this invention The jump rope grip of this invention, equipped with a rotation function, significantly reduces the strain on the shoulder, elbow, and wrist joints. This improves the strained wrist and arm movements commonly seen with conventional jump ropes, allowing exercisers to exercise in a more natural posture. This reduces fatigue even with prolonged use and improves comfort. The reduced strain on the jump rope user's body can help make exercise a habit.

[0013] (3) Adaptability of the grip of this device The grip of the present invention is designed based on the concept of ergonomics, which aims to design objects and environments that allow the jump rope jumper to use them in the most natural way possible, and to incorporate this concept into actual designs. It can accommodate a variety of hand sizes and jumping styles. While not particularly limited, the grip shape of the present invention has an L-shaped grip, with the ratio of the length from the rope attachment point to the grip's rotating portion to the non-rotating portion of the grip ranging from 1:1 to 1:3. Preferably, this ratio is in the range of 1:1.3 to 1:2.6. For example, assuming a total grip length of 18 cm, the ratio is in the range of 9 cm:9 cm to 4.5 cm:13.5 cm. A particularly preferred ratio is 7 cm:11 cm. Furthermore, the diameter ratio of the rotating portion to the non-rotating portion of the L-shaped grip of the present invention ranges from 1:1 to 1:3. Furthermore, a skip rope may also be provided with a function that allows the length of the rope to be adjusted as needed, as in the past. Furthermore, the surface of the grip may be patterned to provide a non-slip function, or the end of the grip may have a protrusion to prevent the hand from slipping off the grip while jumping. Because of these features, the device can be adapted to the needs of each jump rope user. In other words, this device can accommodate a wide range of users, from beginners to professionals, and can also avoid excessive strain on the user's wrists, posture, etc. [Example]

[0014] An embodiment will now be described with reference to the accompanying drawings. A skipping rope with a grip of the present invention was created. The length of the skipping rope shown in Figure 1 (1) was approximately 1.5 meters. The grip section shows the rotating portion of the rope when skipping (2), the rotating portion at the top of the grip (3), and the non-rotating portion at the bottom of the grip (5). As shown in Figures 3 and 4, the rotating portion at the top of the grip (3) and the non-rotating portion at the bottom of the grip (5) are linear before use, but can be rotated as needed using the grip rotation mechanism (4). The rotation angle ranges from 0 degrees (linear) to a maximum of 90 degrees (L-shaped), and can be adjusted in 10-degree increments. Furthermore, the grip of the present invention is provided with anti-slip protrusions (6) around the periphery of the grip as needed. In this example, the grip's rotation mechanism uses an 8mm ball bearing, allowing for smooth rotation of the rope. Furthermore, the grip is approximately 18cm long and 3.5cm in diameter. When using the grip's rotation function (4) to transform it into an L-shape, the handle length becomes approximately 11cm, and the length of the rope attached becomes approximately 7cm.

[0015] As described above, the present invention provides a jump rope grip with a rotating, movable portion. This rotating mechanism allows the user to move naturally while swinging the rope, reducing arm fatigue. Furthermore, at least the outer surface of the non-rotating portion of the grip is made of a non-slip rubber material, improving safety and comfort. Overall, the jump rope is portable and adjustable to accommodate a variety of heights and preferences, allowing for a variety of holding and jumping styles. Using a jump rope with a grip of the present invention allows users to vary their grip style to enhance their exercise routine, thereby achieving flexibility in exercise not possible with conventional, fixed shapes.
