Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, specifically to a jump rope, and more particularly to a jump rope with a non-slip handle. Background Technology

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] Rope skipping is a sport in which various jumping movements are performed within a swinging rope. During use, to make the rope grip more secure, the surface of the rope handle is usually treated with an anti-slip coating to increase friction. However, in some sports, such as freestyle rope skipping, the rope may be used to perform various fancy movements, often involving hand switching and swinging. In these cases, the surface treated with the existing anti-slip technology may actually affect the smoothness of the movements, and the existing anti-slip handles cannot dynamically adjust the friction between the handle and the hand according to the actual grip strength. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a jump rope with an anti-slip handle, which can increase the contact area between the anti-slip layer surface and the hand, and can achieve the effect of dynamically adjusting the friction of the handle according to the grip force.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A jump rope with anti-slip handles includes two handles and a rope body disposed between the two handles. An anti-slip layer is provided on the handles. The anti-slip layer includes a base, multiple fins and multiple elastic connectors. The base is the bottom surface of the anti-slip layer. The fins are connected to the base through the elastic connectors. The anti-slip layer is rolled into a cylindrical shape and covers the outer periphery of the handles. The anti-slip layer is fixedly connected to the handles.

[0007] The fins are set perpendicular to the surface of the base, and multiple fins are distributed at intervals on the surface of the base. The cross-sectional area of ​​the elastic connector is smaller than the cross-sectional area of ​​the fins.

[0008] Preferably, the multiple fins are evenly spaced in a honeycomb pattern, and the height of the fin is less than or equal to the distance between two adjacent fins.

[0009] Preferably, the fin is a cylinder or an elliptical cylinder, and a friction surface is provided on the side wall of the fin.

[0010] Preferably, the end of the fin column away from the substrate is provided with a spherical curved surface.

[0011] More preferably, the diameter of the elastic connector is smaller than the diameter of the fin column, and the elastic connector has a structure that is thinner in the middle and thicker at both ends.

[0012] Furthermore, the base, the fin column, and the elastic connector are integrally formed.

[0013] Preferably, the handle includes a fixed cylinder and a winding cylinder, the fixed cylinder having a winding cavity, and the bottom wall of the winding cavity having a rope hole for the rope to pass through.

[0014] The rope winding cylinder is detachably installed inside the rope winding cavity. After the rope passes through the rope hole, it is fixedly connected to the rope winding cylinder, and a part of the rope can be wound on the rope winding cylinder.

[0015] After the winding drum is connected to the fixed drum, the rope is clamped and pressed against the bottom wall between the winding drum and the winding cavity.

[0016] Furthermore, the rope winding drum includes a mounting plate, a connecting section, and a rope winding section. The connecting section is located between the rope winding section and the mounting plate. The mounting plate, the connecting section, and the rope winding section are coaxially integrated. The rope is fixedly connected to the peripheral wall of the rope winding section near the connecting section. The fixed drum is connected to the rope winding drum through the connecting section.

[0017] Preferably, the connecting section is provided with external threads, and the inner wall of the fixed cylinder near the opening end is provided with internal threads that are compatible with the external threads.

[0018] More preferably, the sum of the lengths of the winding section and the connecting section is greater than the depth of the winding cavity, so that the rope can be held against the bottom wall of the winding cavity by the end of the winding section.

[0019] After adopting the above technical solution, this utility model has the following beneficial effects:

[0020] The jump rope with an anti-slip handle disclosed in this utility model has fins set on the base surface via elastic connectors. The ends of the fins away from the base stand upright, and the plane formed by the ends of multiple fins serves as the contact surface for hand gripping. When a gripping force is applied to the handle, the fins are driven to tilt to one side, causing the elastic connectors to bend, thereby exposing the sidewalls of the fins to the outside and serving as the contact surface for hand gripping. This increases the contact area, thereby increasing the surface friction of the anti-slip layer. The greater the force applied when gripping the handle, the greater the tilting angle of the fins, and the larger the contact area between the anti-slip layer and the hand, i.e., the greater the friction between the anti-slip layer and the hand. When the handle is released, the elastic connector rebounds, allowing the fins to return to their original shape, and the friction of the anti-slip layer on the handle surface returns to its initial value. This achieves the effect of dynamically adjusting the handle friction according to the gripping force. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments. The same reference numerals in the accompanying drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example 1

[0029] Reference Figure 1 and Figure 2 As shown, this utility model provides a jump rope with anti-slip handles, including handles 1 and rope body 2. There are two handles 1, which are respectively connected to the two ends of the rope body 2. Each handle 1 is provided with an anti-slip layer 3.

[0030] Reference Figure 2 and Figure 3 As shown, the anti-slip layer 3 includes a base 31, multiple fins 32, and multiple elastic connectors 33. The base 31 is the bottom surface of the anti-slip layer 3, and the fins 32 are connected to the base 31 through the elastic connectors 33. The anti-slip layer 3 is rolled into a cylindrical shape and covers the outer periphery of the handle 1, and the anti-slip layer 3 is fixedly connected to the handle 1.

[0031] In this embodiment, the fin pillars 32 are arranged perpendicular to the surface of the base 31. Multiple fin pillars 32 are provided and are spaced apart on the surface of the base 31 so that the surface of the base 31 is covered with fin pillars 32.

[0032] The elastic connector 33 is disposed between the fin post 32 and the base 31. Each elastic connector 33 corresponds to each fin post 32 and serves as a bending hinge for the fin post 32. When the fin post 32 is tilted, the elastic connector 33 will bend and deform to expose the side wall of the fin post 32, thereby increasing its contact area with the hand.

[0033] When the handle 1 is not gripped, the end of the fin 32 furthest from the base 31 stands upright. When a gripping force is applied to the handle 1, the fin 32 tilts to one side under the force, causing the elastic connector 33 to bend. This allows the sidewall of the fin 32 to conform to the hand, increasing its contact area. The greater the gripping force applied to the handle 1, the greater the tilting angle of the fin 32, resulting in a larger contact area between its sidewall and the hand, and thus greater grip friction. When the gripping force applied to the handle 1 disappears, the elastic connector 33 springs back under elasticity, restoring the fin 32 to its original vertical shape. This achieves the effect of adaptively changing the friction force according to the pressure applied to the handle 1. Furthermore, because the contact area between the fin 32 and the hand varies under different pressures, the friction force at the same location does not decrease due to repeated friction, thus significantly improving wear resistance. Additionally, since the fin 32 and the elastic connector 33 are bendable and movable, cleaning is convenient.

[0034] In other embodiments, the fin column 32 may also be at a certain angle to the surface of the base 31, thereby increasing the initial frictional force and causing the fin column 32 to tilt to the same side as much as possible when subjected to force, thereby avoiding the situation where multiple fin columns 32 obstruct each other.

[0035] In some embodiments, refer to Figure 4 Multiple fins 32 are evenly spaced in a honeycomb pattern, with each fin 32 located at the center of a hexagonal honeycomb. With the same spacing, the honeycomb distribution requires the fewest fins 32, thus reducing the manufacturing cost of the anti-slip layer 3. Furthermore, using a mathematically optimal honeycomb structure ensures that the friction surface coverage formed by the fins 32 is no less than 85%. To avoid localized stress concentration, the spacing between each fin 32 and its surrounding fins is the same, resulting in a more even distribution of the force applied to the handle 1. In other embodiments, depending on the actual situation, the fins 32 can also be arranged in a uniform array, such as a square or triangular distribution.

[0036] In some embodiments, the height of the fin column 32 is less than or equal to the distance between two adjacent fin columns 32. That is, when the fin column 32 is fully tilted, by making the height of the fin column 32 less than or equal to the distance between two adjacent fin columns 32, the fin column 32 will not press on another adjacent fin column 32 or be obstructed by a nearby fin column 32, thereby allowing the side of the fin column 32 to be fully exposed as a friction surface, which improves the utilization effect of the fin column 32. In this embodiment, when the fin column 32 is fully tilted, the fin column 32 can contact another adjacent fin column 32, effectively improving the friction force when the handle 1 is subjected to force.

[0037] In some embodiments, the fin column 32 is a curved cylinder. When the fin column 32 is tilted under force, since the direction of the force may be arbitrary, the fin column 32 is set as a curved cylinder with continuous curved sidewalls to avoid the appearance of sharp edges after the fin column 32 tilts, which would affect the surface friction. In this embodiment, the fin column 32 is a cylinder so that the friction force is the same no matter which direction the fin column 32 tilts. In other embodiments, the fin column 32 may also be a curved cylinder with an elliptical cross section, so that its friction force adjustment has direction to meet the needs of some specific situations.

[0038] In some embodiments, a friction surface is provided on the sidewall of the fin post 32. Specifically, the sidewall surface of the fin post 32 can be roughened, or a friction layer with a larger coefficient of friction can be provided on its sidewall to increase its friction force.

[0039] In some embodiments, the end of the fin post 32 furthest from the base 31 is configured as a spherical curved surface. When the gripping force on the handle 1 is less than a certain threshold, the fin post 32 does not tilt to expose the side wall, and the end of the fin post 32 is always located on the outer side as the gripping contact surface. In this embodiment, the end of the fin post 32 can be smoothed, thereby further reducing its friction when not under force, thus making its dynamic adjustment range of friction larger.

[0040] In some embodiments, the cross-sectional area of ​​the elastic connector 33 is smaller than the cross-sectional area of ​​the fin post 32, that is, the diameter of the elastic connector 33 is smaller than the diameter of the fin post 32. In this embodiment, the elastic connector 33 is a flexible column with deformation elasticity. In this embodiment, the diameter of the fin post 32 is 0.5 to 1 mm, the height of the fin post 32 is 1.5-2 mm, the height of the elastic connector 33 is 0.5-1 mm, and the diameter of the elastic connector 33 is 0.2-0.3 mm. In other embodiments, the elastic connector 33 can also be configured as a waist-shaped structure that is thinner in the middle and thicker at both ends. The diameter of the elastic connector 33 with this structure can be 0.1-0.5 mm from its minimum to its maximum.

[0041] In this embodiment, the base 31, fin 32, and elastic connector 33 are integrally formed from the same material. The material can be liquid silicone with a Shore hardness of 40A and an elastic modulus of 0.8MPa after vulcanization. This ensures that the elastic recovery force provided by the elastic connector 33 can guarantee a bending and rebound life of 100,000 cycles. The connection position between the elastic connector 33 and the fin 32 is treated with a continuous curved surface to avoid sharp corners, thereby making the contact surface formed after the fin 32 is tilted more uniform.

[0042] Example 2

[0043] In some other embodiments, reference is made to Figure 5 The handle 1 includes a fixed cylinder 12 and a winding cylinder 11. A cylindrical winding cavity 121 is coaxially formed inside the fixed cylinder 12. A rope hole 122 coaxial with the fixed cylinder 12 is formed on the bottom wall of the winding cavity 121. The winding cylinder 11 is detachably installed inside the winding cavity 121. The rope body 2 passes through the rope hole 122 and is fixedly connected to the winding cylinder 11. Specifically, the winding cylinder 11 includes a mounting plate 111, a connecting section 112, and a winding section 113. The connecting section 112 is located between the winding section 113 and the mounting plate 111. The mounting plate 111, the connecting section 112, and the winding section 113 are coaxially integrated in sequence. The rope body 2 is fixedly connected to the peripheral wall of the winding section 113 near the connecting section 112. The fixed cylinder 12 is connected to the winding cylinder 11 through the connecting section 112. When in use, take out the rope winding cylinder 11, and then wind the rope 2 around the winding section 113, or remove the rope 2 wound on the winding section 113 to achieve the effect of adjusting the length of the rope 2 between the two handles 1.

[0044] The connecting section 112 is provided with an external thread, and the inner wall of the fixed cylinder 12 near the opening is provided with an internal thread that matches it. The fixed cylinder 12 and the rope winding cylinder 11 are more stable through the threaded connection. In other embodiments, the connecting section 112 and the fixed cylinder 12 can also be tightly inserted by an interference fit.

[0045] The sum of the lengths of the rope section 113 and the connecting section 112 is not less than the depth of the rope cavity 121. Since a section of the rope body 2 is located between the bottom wall of the rope cylinder 11 and the rope cavity 121, the above arrangement ensures that when the rope cylinder 11 is installed into the fixed cylinder 12, the rope body 2 can be held by the rope section 113 and the bottom wall of the rope cavity 121, thereby preventing the rope body 2 from slipping during the use of the jump rope.

[0046] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
