Description

Impact cushioning protector

The novel creation relates to a protective gear, in particular to an impact cushioning protector having mechanical strength and resilience.

Wear sports gear, such as knee pads, elbow pads, etc., in sports or athletics such as ice rinks, baseball fields, biking, riding locomotives, football fields, etc., to prevent sports injuries or to reduce injuries when falling. The usual way of degree. However, there are several shortcomings in the current protective gear on the market. For example, for a high-strength protective gear that requires a baseball catcher, there is often a problem of bulkiness and brittleness, which limits the range of motion and is prone to cuts and the like when broken. However, materials that absorb strong impact generally have problems of insufficient mechanical strength and difficulty in forming.

In addition, the general protective material is not breathable, and most people feel hot and humid after wearing, so the body discomfort makes the heart easily repel. Therefore, in a generally informal situation, the situation in which the user speculates and chooses not to wear the protective gear is improved. These problems can make the degree of injury increase when the injury actually occurs. Therefore, there is a need for a protective gear that solves the above problems.

The second elastic layer is disposed on one side of the first elastic layer, and is a three-dimensional structure formed by cross-linking a plurality of thermoplastic fibers, and the rebound of the second elastic layer is greater than that of the first elastic layer and the second elastic layer. The density is less than the first elastic layer.

In one embodiment, the body is a single piece of fabric, and the body is provided with a plurality of connecting portions for connecting a plurality of wearing members.

In one embodiment, the body is a flexible tubular web.

In an embodiment, the cushioning member is disposed in at least one interlayer of the body.

In one embodiment, the cushioning member is combined with the body with a button or zipper.

In an embodiment, the first elastic layer and the second elastic layer are bonded to each other by an adhesive layer.

In an embodiment, the first elastic layer is further provided with at least one through hole.

In one embodiment, the first elastic layer has a resilience of 40 to 70%, a density of 100 to 200 kg/m ³ , a second elastic layer having a resilience of 60 to 100%, and a density of 40 to 150 kg/m ³ . When the first elastic layer is subjected to a compressive stress ranging from 40 to 365 kPa, the strain of the first elastic layer ranges from 10 to 65%.

In one embodiment, the first elastic layer is formed by vapor fusion of a plurality of expanded particles, wherein the expanded particles comprise expanded thermoplastic polyurethane (E-TPU), At least one of expanded polyethylene (E-PE) and expanded polypropylene (E-PP). The thermoplastic fibers of the second elastic layer comprise thermoplastic polyurethane (TPU) fibers.

Based on this, the new creative owner provides high strength and impact resistance by providing mechanical strength and resilience of the cushioning member, and provides light and breathable characteristics to improve the willingness of the general user to wear, thereby reducing the damage. .
