Shoe body for lightweight skates

The present invention relates to a shoe body for skates, and more particularly to a shoe body for lightweight skates.

As people become more and more aware of the need for exercise, many sports products have also flourished. In order to prevent people from being injured by accidents in dynamic activities, equipment suitable for the sport should be worn before engaging in various sports, and the equipment will be designed with different functions according to different types of sports, so as to reduce the occurrence of sports injuries by the equipment.

Taking skates as an example, because the speed of skating is faster, the site is harder, and the activity environment is colder, whether it is ice skates or traditional four-wheeled skates, it is generally necessary to design the body of the skates as It has the function of resisting high-intensity impact and keeping warm, so as to protect the athlete's foot in time and prevent the athlete from causing sprain, contusion or frostbite during the activity.

In order to combine the foregoing functions, a shoe body generally used for an ice skate includes a sole, a shell layer, a leather layer, a buffer layer, an impact layer, an elastic layer, an inner buffer layer, a wool layer and a lining. And the combination of various soft and hard materials is fixed by gluing or stitching. The sole is generally made of wood to support the entire body of the skate, and can be easily combined with the ice skate assembly or the conventional four-wheel assembly. However, the sole of the wooden material increases the weight of the shoe body generally used for the skate. It is inconvenient to carry, and because the texture of the wooden material is relatively hard and inelastic, it is usually necessary to add a buffer layer and an elastic layer to increase the elasticity and soothe the impact of the foot, which will make the shoe body for the skates The weight increases, which may affect the portability of the athlete's movement.

Due to the above problems, the purpose of this creation is to reduce the weight of the shoe body for the skates, so that the athlete can move on the ice surface more lightly.

To achieve the foregoing objective, the present invention provides a shoe body for a lightweight skate, comprising: a shoe shell having a sole and a shoe body extending from the sole, and the sole and the body Forming an accommodating space, the shoe shell is made by plastic injection molding; and an insole comprising a rear foot portion and a front foot portion extending from the rear foot portion, the insole is formed by a plastic injection molding The insole is placed in the accommodating space of the shoe shell, and the size and shape of the insole correspond to the size and shape of the accommodating space of the shoe shell.

Since the size and shape of the insole correspond to the size and shape of the housing space of the shoe shell, and the shoe shell and the insole are both formed by injection molding of a plastic material, the creation can be directly formed into one piece. The insole is disposed in the accommodating space of the integrally formed shoe shell, thereby eliminating the limitation of the prior art that the shoe body is made by gluing or sewing a plurality of layers of soft or hard materials, and reducing the weight of the shoe body for the skate. . Accordingly, the skates made by the shoe body of the present invention for lightweight skates can have the advantages of light weight, so that the weight during carrying and the weight of the skater when wearing can be reduced, so that the skater can Move lightly on the ice.

Preferably, the shoe case and the insole of the present invention are produced by injection molding of a low-density plastic material, which may be low-density polyethylene (LDPE), but not limited thereto. this.

In addition, this creation can use different materials of plastic as raw materials for different purposes, to produce high-strength shoe shells, insoles or high-elastic shoe shells, insoles. The high-strength shoe shell can be injection molded from a high-strength plastic material such as high-density polyethylene (HDPE), polypropylene (PP) or nylon (nylon) to enhance the protection of the shoe shell. The high elastic insole can be injection molded from a thermoplastic elastomer (TPE) to enhance the cushioning effect of the insole. Further, the high elastic insole may be a thermoplastic polyether ester elastomer (TPEE, such as HTYREL sold by DuPont), a thermoplastic polyurethane (TPU) or a thermoplastic (thermoplastic). Rubber, TPR) and other elastic plastic materials are injection molded.

Preferably, the shoe body has a plurality of streamline ribs protruding from the surface of the housing space; more preferably, the streamline ribs are formed along the long end of the shoe shell. The streamline ribs reduce the resistance of the athlete when moving, allowing the skater to move more quickly, and can increase the aesthetics of the shoe-type for lightweight skates.

Preferably, the insole has an upper surface and a lower surface, the lower surface of the rear foot abuts the sole, and the rear foot has a plurality of grooves, and the grooves are formed by the rear foot The upper surface is recessed downwardly.

Preferably, the insole is provided with a plurality of ribs longitudinally convexly contacting the surface of the sole. The ribs are partially deformed after being stressed, so the arrangement of the ribs can impart a cushioning function to the insole and slow the impact of the foot on the impact.

Preferably, the ribs are interconnected to form a plurality of hollow polygons. By varying the arrangement of the ribs, different parts of the insole can be subjected to different proportions and directions of force.

Preferably, the shoe body for the lightweight skate includes a warm layer that abuts the shoe body of the shoe shell and is placed in the housing space of the shoe shell. The shoe body for lightweight skates can be warm and comfortable by the combination of the shoe shell and the warm layer.

Preferably, the sole of the shoe shell is formed with a plurality of perforations. By means of the arrangement of the perforations, the shoe shell can be combined with an ice skate assembly or a conventional four-wheel assembly to form a lightweight skate skate or a lightweight conventional roller skate.

Preferably, the insole is formed with a plurality of through holes, and the through holes of the insole communicate with the through holes of the sole. The shoe shell, the insole is combined with a skate assembly or a conventional four-wheel assembly by the perforation of the insole and the through hole of the shoe shell, thereby simultaneously fixing the shoe shell, the insole and the ice skate/tradition Three wheel assemblies are used to make lightweight skate skates or lightweight traditional roller skates.

In summary, the shoe body of the present invention for lightweight skates can help to reduce the weight of the overall skate body, making it easier for the skater to move on the ice; in addition, the ribs of the insole can be more Improve the effectiveness of foot cushioning and support.

Referring to FIG. 1, a first preferred embodiment of the shoe body 1 for a lightweight skate according to the present invention includes a shoe casing 10 and an insole 20, the shoe casing 10 having a shoe shape having a a sole 11 and a shoe body 12 extending upwardly from the sole 11 , the sole 11 and the body 12 define an accommodating space 13 , and the insole 20 is placed in the accommodating space 13 of the shoe shell 10 and attached Relying on the sole 11 of the shoe shell 10.

Referring to FIG. 2 and FIG. 3 together, the shoe casing 10 is formed by injection molding of thermoplastic plastic, and the shoe casing 10 of different sizes and shapes can be made by using different sizes and shapes of the mold.
