  The sports mouthpiece 1 of the present embodiment includes a pair of protective portions 3 and 3 that cover the occlusal surfaces of the left and right molars, and a locking member 5 that connects the protective portions 3 and 3 together.

Each protection part 3 includes a plate-like piece 7 disposed at a position corresponding to the occlusal part of the molar tooth, and an outer piece formed by extending downward from the lateral outer edge of the plate-like piece 7 into a rectangular plate shape. 11 and an inner piece 13 formed to extend downward from the inner edge of the left and right direction of the plate-like piece 7 into a rectangular plate shape, and the protection part 3 is formed in a substantially U-shape with a cross-section downward.
That is, a downward substantially U-shaped groove is formed by the outer piece 11, the inner piece 13, and the plate-like piece 7 at both left and right ends of the mouthpiece 1 of the present embodiment.

  The lower end portion 11a of the outer piece 11 is formed to bulge inward in the left-right direction so as to have a substantially circular cross section.

The thickness of the plate-like piece 7 of each protection part 3 is about 0.5 mm to 5 mm.
Further, the plate-like piece 7 is formed so that the thickness of the front end 7a becomes thinner from the front end 7a to the rear end 7b so as to be 1.5 to 3 times the thickness of the rear end 7b.
For example, the thickness of the front end 7a is 1 mm to 4 mm, and the thickness of the rear end 7b is 0.5 mm to 2 mm. In this embodiment, the thickness of the front end 7a of the plate-like piece 7 is twice the thickness of the rear end 7b.

Further, the plate-like piece 7 has a curved surface shape with the center portion in the front-rear direction slightly lowered downward.
Specifically, the plate-like piece 7 is formed so as to be inclined in an arcuate shape so that the rear half is lifted upward from the front half.

  The outer piece 11 and the inner piece 13 are formed so that the vertical dimension becomes shorter as going to the back side.

  Further, the outer piece 11 and the inner piece 13 are formed up to the middle of the plate-like piece 7 so as to end slightly forward from the rear end portion of the plate-like piece 7.

  Furthermore, the outer piece 11 and the inner piece 13 formed at the left and right ends of the plate-like piece 7 of each protection portion 3 are formed so as to approach each other as they go downward.

  The locking member 5 is formed in a substantially U shape and is arranged so as to cover the back side of the teeth along the dentition, and both end portions 5 a and 5 a thereof are connected to the lower end portion of the inner piece 13 of each protection portion 3. Has been.

  Since the locking member 5 has a curved shape, the compatibility with the dentition is improved. Moreover, in order to make the fitting to a tooth more reliable, the locking member 5 is formed in a substantially U-shape that is slightly wider than the tooth row. That is, the left and right end portions 5a, 5a of the locking member 5 are shaped to be slightly expanded outward in the left-right direction. Thus, when the sports mouthpiece 1 is mounted in the oral cavity, the left and right end portions 5a, 5a of the locking member 5 are elastically deformed so as to be slightly close to each other and mounted on the teeth, and the gums are restored by elastic restoration after mounting. It will stick to the inside.

Both end portions 5 a and 5 a of the locking member 5 are connected to the lower end portion of the inner piece 13 of each protection portion 3.

If the distance x is too small, it is easy to hit the tongue, and if it is too large, the stability is insufficient.
The vertical dimension (height dimension) y of the locking member 5 is preferably about 3 to 8 mm, more preferably 4 to 6 mm, and 5 mm in the illustrated example.
If the vertical dimension y is too small, it becomes easy to twist, and if it is too large, it becomes bulky in the mouth.

Next, the use of the sports mouthpiece 1 of the present embodiment will be described.
FIG. 5 is a cross-sectional view showing a wearing state of the sports mouthpiece of the present embodiment.
FIG. 6 is a view showing a state in which the lower molars are fitted into the protector and meshed with each other.

First, the mouthpiece 1 is put in the oral cavity, and the locking member 5 is arranged along the back side of the lower tooth. Then, as shown in FIG. 6, the lower molar teeth are engaged and attached to the downward substantially U-shaped groove formed by the outer piece 11, the inner piece 13 and the plate-like piece 7.
When the mouthpiece 1 is thus mounted in the oral cavity, the locking member 5 comes into contact with the lower end portion of the lower front tooth, that is, the boundary portion between the lingual tooth and the gum.

Since the outer piece 11 and the inner piece 13 are formed so as to be close to each other, the downward substantially U-shaped groove constituted by the plate-like piece 7, the outer piece 11 and the inner piece 13 is elastically deformed to lower the lower piece. By forcibly fitting to the molars, it can be difficult to come out of the teeth and can be stably fixed to the teeth.
Further, in a state where the mouthpiece 1 is mounted on the lower teeth, the lower end portion 11a of the outer piece 11 enters the recess u on the side surface of the lower molar tooth, and the mouthpiece 1 is stably fixed.

  Further, when the mouthpiece 1 is placed in the oral cavity, the left and right end portions 5a of the locking member 5 are connected to the lower end portion of the inner piece 13 and the vertical dimension of the locking member 5 is made small. It can be worn without a foreign object feeling, and conversation is easy even if the mouthpiece 1 is worn.

Further, by forming the plate-like piece 7 into an arcuate shape, the plate-like piece 7 is arranged along the arch of the dentition in a state where the mouthpiece 1 is attached, and a structure that can be easily bitten is obtained.
Furthermore, since the front end 7a of the plate-like piece 7 is formed thicker than the rear end 7b, it can be evenly engaged.

  Thus, various sports can be performed with the mouthpiece 1 mounted in the oral cavity. By mounting the mouthpiece 1 according to the present invention, even if the teeth are strongly engaged, the teeth hit the plate-like piece 7 equally and stably, and the teeth are not lost.

  Of the locking member 5 and the protection part 3, at least the protection part 3 is formed of a flexible rubber-like elastic material. In this embodiment, both the locking member 5 and the protection portion 3 are integrally formed of a flexible rubber material such as silicon rubber, urethane rubber, rubber, EVA resin (ethylene-vinyl acetate copolymer resin), or elastomer. Has been. Note that at least the plate-like piece 7 of the protection portion 3 is configured to have an elastic force that is slightly elastically deformed by the bite of the molar and is restored to its original state by releasing the bite.

  The sports mouthpiece of the present invention is not limited to the configuration of the above embodiment, and can be changed as appropriate. For example, in the above embodiment, the locking member 5 is provided so as to connect the inner pieces 13 and 13 and is arranged so as to cover the back side of the tooth, but the locking member is provided so as to cover the front side of the tooth. It may be provided. That is, it is good also as a structure which provides the locking member 5 so that the outer pieces 11 and 11 may be connected.
