Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, specifically to an agile ladder that is easy to fold and store. Background Technology

[0002] The agility ladder, also known as the speed ladder, is a functional training device used to improve athletes' footwork, coordination, and dynamic balance. Its main body consists of a trapezoidal structure made up of parallel horizontal bars, which is placed flat on the ground. Users move quickly between the ladder sections using specific footwork techniques to enhance neuromuscular control.

[0003] Currently, mainstream agile ladder products on the market are made of soft polymers (such as PP plastic and ABS plastic) or polyester fiber ropes, which are both flexible and wear-resistant, and can maintain the shape of the ladder to a certain extent.

[0004] Agility ladders are important equipment for training children's agility and are often used in children's physical fitness training. They are used frequently and need to be stored and retrieved often. Existing agility ladders (multi-functional agility butterfly ladders) will deform after being stored and folded for a long time, and the steps will easily fall apart and take up space. In addition, folding agility ladders is time-consuming and laborious, and it is not easy for some people with less strength to fold and store them. Utility Model Content

[0005] The purpose of this invention is to develop an agile ladder that is easy to fold and store, in order to solve the problems of existing agile ladders being inconvenient to fold and store and the steps spreading out and easily deforming after folding, thereby improving the storage efficiency of the agile ladder and making the stored agile ladder less prone to deformation.

[0006] This utility model is achieved through the following technical solution:

[0007] A foldable and easy-to-store ladder includes several interconnected rectangular frames. Each rectangular frame includes four flexible ladder ropes, which are connected end-to-end to form the four sides of the rectangular frame. Each flexible ladder rope contains two sets of magnetic assemblies, each comprising a long, thin magnetic strip and a carbon steel strip. The magnetic strip and carbon steel strip are arranged side-by-side and abutting each other within the flexible ladder rope. The two sets of magnetic assemblies are spaced apart along the length of the flexible ladder rope. The sides of adjacent rectangular frames are connected by a flexible connecting strip. The flexible ladder ropes and flexible connecting strips can be polypropylene braided ropes. The magnetic assemblies can be inserted during the weaving of the flexible ladder ropes or made into a braided sleeve, with the magnetic assemblies positioned within the braided sleeve.

[0008] The beneficial effects of the above technical solution are as follows: four flexible ladder ropes serve as the sides of the rectangular frame of the agile ladder, and two sets of magnetic components are set at intervals in each flexible ladder rope (i.e., the interruption between the two sets of magnetic components is a flexible connection). The carbon steel strips serve as support strips and also attract magnetic strips in other parts when the ladder ropes are folded; the sides of two adjacent rectangular frames are connected by flexible connecting strips; when folding the agile ladder, the rectangular frames overlap each other, the magnetic components attract each other, and one rectangular frame can be folded twice. That is, the minimum planar projection of the agile ladder after folding can be one-quarter of the area of ​​a rectangular frame. During the folding process, the magnetic components attract and align each other, which facilitates neat folding, makes it easy to store and prevents it from falling apart. After storage, it can be laid flat, and the rope ladder is not easily deformed.

[0009] Furthermore, the surface of the flexible ladder rope is provided with fluorescent strips; the fluorescent strips on the exterior of the rope ladder can clearly display the outline of the agility ladder in low-light environments, effectively ensuring the training process and the safety of the trainees; the fluorescent strips can be fixed to the surface of the flexible ladder rope by sewing or other means, or, in one possible embodiment, the fluorescent strips can be detachably connected to the surface of each flexible ladder rope by pasting or magnetic attraction.

[0010] Furthermore, each flexible ladder rope is provided with two segments of fluorescent strips, and each segment of fluorescent strips corresponds to the length and position of the magnetic attraction component; the fluorescent strips on the flexible ladder ropes are segmented, so that the fluorescent strips will not be folded when the agile ladder is folded and stored, effectively extending the life of the fluorescent strips, and without affecting the shape and outline of the agile ladder.

[0011] In one possible implementation, the flexible ladder rope has a rectangular or near-rectangular cross-section. Based on existing rope ladders, the original cylindrical ladder rope is improved to have a rectangular or near-rectangular cross-section, making it easier to grip the ground. The flexible ladder rope can be made of polypropylene braided rope, which has advantages such as light weight, high strength, high elongation, good abrasion resistance, and chemical corrosion resistance, making it suitable for long-term outdoor use. Furthermore, the rope ladder incorporates a magnetic attraction component, increasing its self-weight and ensuring stable placement during use, preventing it from being blown away in windy conditions.

[0012] In one possible implementation, the rectangular frame is square, and two sets of magnetic assemblies on each flexible ladder rope are symmetrically distributed on both sides of the midpoint of the flexible ladder rope, so that the eight magnetic assemblies on the rectangular frame are axially symmetrical with respect to any axis of symmetry of the rectangular frame. The square rectangular frame has multiple axes of symmetry, so whether a single rectangular frame is symmetrically folded first and then overlapped with other rectangular frames, or several rectangular frames of the agile ladder are overlapped first and then folded a second time, it can ultimately be stored as a block structure, which is convenient for storage.

[0013] In one possible implementation, the width of the flexible connecting strip is not less than the thickness of the flexible ladder rope wrapping the magnetic component. When folded, the rectangular frames overlap each other, and the width of the flexible connecting strip is not less than the thickness of the flexible ladder rope, so that the folded rectangular frames overlap flatly, while avoiding excessive stretching of the flexible connecting strip.

[0014] In one possible implementation, the surface of the flexible ladder rope has an anti-slip texture, which refers to the flexible ladder rope having a rough surface. Alternatively, anti-slip grooves or anti-slip protrusions may be provided on the surface of the flexible ladder rope. Attached Figure Description

In basketball training, it can be folded into a frame shape, allowing students to simulate jumping under the basket, improving jump height and landing stability. In children's physical education classes, it can be used to improve students' agility and for footwork exercises.

[0027] The flexible ladder rope is made of polypropylene braided rope with a thickness of ≥18 mm. Polypropylene is lightweight, strong, has high elongation, good abrasion resistance, and chemical corrosion resistance, making it suitable for long-term outdoor use. The carbon steel strips inside the flexible ladder rope allow it to maintain its shape even when unfolded at high temperatures. A long bar magnet is installed at each end of the flexible ladder rope, with nothing placed between the two long bar magnets (only for flexible connection), leaving space for folding.

[0028] In one embodiment, the surface of the flexible ladder rope is provided with a fluorescent strip 13; the fluorescent strip 13 on the exterior of the rope ladder can clearly display the outline of the agility ladder in low lighting conditions, effectively ensuring the training and ensuring the safety of the trainees; the fluorescent strip 13 is sewn onto the surface of the flexible ladder rope, or the fluorescent strip 13 can be detachably connected to the surface of each flexible ladder rope by Velcro or magnetic attraction.

Figure 1 It is one-quarter the size of a rectangular frame, making it easy to store.

[0032] In one embodiment, the width of the flexible connecting strip 2 is not less than the thickness of the flexible ladder rope wrapping the magnetic component.
