Description

Protective mask for sports

The present invention relates to a protective mask, and more particularly to a sports protective mask that is worn on a user's head and that blocks forward and lateral impactors from the user.

In general sports, athletes such as baseball catchers, softball catchers, etc., often suffer from frontal and side impactors such as high-speed balls, in order to prevent the athlete from hitting the face during impact. Athletes participating in this type of exercise must wear a protective mask on their head that can block the front and sides of the face. The structure of the conventional protective mask 1 is substantially as shown in Fig. 1, and the protective mask 1 is usually worn in front of the athlete's face by a cushioning protector.

The conventional protective mask 1 uses a welding technique to form a plurality of metal strips into a body shape, and includes a first rod 11 surrounded by a closed loop shape, a bent U shape and a top end welded to the first rod. a second bar 12 on the strip 11 , a third bar 13 which is C-shaped and laterally welded to the first bar 11 and the second bar 12 , and a straddle welded to the first bar 11 And the fourth bar 14 of the second bar 12, one of the closed loops and welded between the fourth bar 14, the first weld 11 and the second bar 12 The fifth bar 15 and a plurality of rod-shaped sixth bars 16 are provided. That is, the protective mask 1 is basically bent by a plurality of metal rods, and then fixed to the joint portions of the first to sixth rods 11 to 16 by welding. In addition, the early protective mask 1 is usually manufactured using solid iron bars. Due to the heavy weight of the iron bars and the uncomfortable wearing, some protective masks 1 have been manufactured using aluminum alloy rods in recent years.

Conventional protective mask 1 is manufactured, although artificial In the manner of welding, the first to sixth bars 11 to 16 are welded together to form a protective mask 1 of a body shape. However, the threshold of the welding technology is low, and the labor cost is also high. In addition, the surface of the welding point at the right-angle overlapping portion cannot be uniform, and the finished product is not aesthetically pleasing, and the trimming is also difficult. When the protective mask 1 is hit, It is also relatively easy to break from the solder joint. Therefore, the conventional protective mask 1 does have a lack of aesthetics, high artificial dependency during manufacturing, and poor safety.

The purpose of the present invention is to provide a sports protective mask that can reduce labor costs and improve the texture and safety of the finished product.

The protective mask of the present invention comprises: two protective frames integrally formed of a metal material, each protective frame includes a protective portion for protecting the face of the user, and two spaced joints, the combination of the protective frames And fixedly combined.

The beneficial effect of the novel is that: by using the combination of the integrally formed protective frames, in addition to minimizing the welding points, the texture of the finished product can be improved, the labor cost can be reduced, and the solder joints of the conventional ones can be improved. It is more prone to breakage and thus increases the safety of the protective mask when in use.
