Detailed Description
Hereinafter, a mode for implementing the protective eyewear of the present invention will be described in detail based on the drawings.
As shown in fig. 1 to 5, the protective spectacles of the present invention are formed by integrating a hard front frame 1 and a soft rear frame 2, wherein a lens 3 is provided on the front frame 1, and a headband 4 is provided on the rear frame 2 so that the periphery of the rear frame 2 is in close contact with the face of a user. The glasses shown in the drawings are made as separate pieces and fitted together to form an integrated glasses, but they may be fused or bonded together to form an integrated glasses. Further, the hard synthetic resin and the soft synthetic resin may be molded simultaneously by double injection to be integrated.
The front frame 1 is formed of a hard synthetic resin or the like, and surrounds the lens 3 to tightly hold the lens 3. The upper side portion 1a and the lower side portion 1b of the front frame 1 are provided with vent holes V leading to the inside of the lens 3. In order to provide such a vent hole V, the vent hole V is easily provided by making the front frame 1 thicker at the portion where the vent hole V is provided, as shown in the drawing. In the present invention, hard means relatively hard as compared with soft of the rear frame 2, but from the viewpoint of strength, it is preferable to set the shore hardness of the front frame 1 to 90 or more.
The rear frame 2 is made of a soft synthetic resin or the like, and its contact surface is shaped to follow the forehead, the periphery of the eyes, the nose bridge or the like of the wearer, so as to be easily attached to the face of the wearer. The rear frame 2 is extended from both ends of the front frame 1 to serve as elastic deformation portions 5, the headband mounting portions 6 are protruded from front side ends of the elastic deformation portions 5, and the temple contact portions 7 are extended from rear side ends of the elastic deformation portions 5. A water reservoir 8 is formed in the center of the upper side portion 2a of the rear frame 2, and a drain hole D leading to the outside of the lens 3 is formed in the bottom of the water reservoir 8. In the present invention, soft means a material having a shore hardness of 60 or less, and in the present invention, the shore hardness of the rear frame 2 can be set to 30 to 60, but preferably 45 to 55. By adopting such shore hardness, the rear frame 2 can be very easily attached to the wearer's face.
The lens 3 is made of hard glass or synthetic resin, and although the illustrated lens is a binocular lens, it may be implemented as a monocular lens. In the present invention, it is desirable to provide the lens 3, but the present invention can be implemented without providing the lens 3.
The headband 4 is formed of an elastic member such as rubber or synthetic resin, and the headband mounting portions 6 mounted to both ends of the rear frame 2 in a freely adjustable length are tightened and loosened to fit around the head of the wearer.
As shown in fig. 8 and 9, the elastic deformation portion 5 is separated into a front deformation portion 9 and a rear deformation portion 10 by a vertical through hole Ha, the front deformation portion 9 is formed in a thick plate shape, and the rear deformation portion 10 is separated into an upper rod portion 10a and a lower rod portion 10b by a horizontal through hole Hb. The longitudinal through hole Ha and the lateral through hole Hb of the elastic deformation portion 5 open to the inside of the lens 3. As shown in fig. 8, the area ratio of the longitudinal section a of the front side deformation portion 9 to the longitudinal section B of the rear side deformation portion 10 is set to 1: 4-5, and the area ratio of the longitudinal section Bu of the upper rod part 10a to the longitudinal section Bd of the lower rod part 10b is 1: 0.8 to 1.2. By adopting such an area ratio, the degrees of deformation in the front-back direction and the up-down direction of the elastic deformation portion 5 can be balanced, and thus deformation (distortion) of the protective eyeglasses at the time of collision can be more effectively suppressed.
The headband mounting portion 6 is made of hard synthetic resin or the like, and as shown in fig. 5, two longitudinal slit holes 6a and 6b are formed from the outside to the inside. In order to attach the headband 4 to the headband attachment portion 6, one end portion of the headband 4 is inserted from the back side to the front side of the inner longitudinal slit hole 6b, and one end portion of the headband 4 is inserted from the front side to the back side of the outer longitudinal slit hole 6a and protrudes to the outside of the headband attachment portion 6. The headband mounting portion 6 is not particularly limited in its structure, and the headband 4 may be mounted so as to be adjustable in length.
The temple contact portion 7 is formed of a soft synthetic resin or the like similar to the rear frame 2, and is formed in a substantially tongue shape, and a plurality of ribs 7a are formed on the front side in the width direction so as to be easily bent in the outward direction, and the rear side is formed as a smooth surface so as to be easily attached to the temple of the wearer.
Further, as shown in fig. 5, the headband mounting portion 6 and the temple contact portion 7 are arranged substantially in parallel so that the inclination angles α, β with respect to the front surface of the protective eyeglasses are both 90 to 100 degrees, and the two inclination angles α, β are substantially equal, whereby the force tends to become smaller than this angle along the inclination angle α of the headband mounting portion 6 and the inclination angle β of the temple contact portion 7 tends to become smaller than this angle due to the tightening of the headband 4, and the temple contact portion 7 is more strongly adhered to the temple of the wearer.
When the protective eyewear of the present invention thus constructed is worn, the soft rear frame 2 is entirely in close contact with the wearer's face, and therefore, even if an impact is applied by a flying object such as a ball, a human being, or a collision with an object during ball sports or winter sports, the impact can be absorbed and relaxed more effectively, and the eyes can be protected more sufficiently. Further, the illustrated examples passed the high-speed impact test by a stud ball of ASTM F803-11 in the standards set by the American Society for Testing Materials (ASTM International: American Society for Testing and Materials).
In the protective eyewear of the present invention, the elastic deformation portion 5 of the rear frame 2 is deformed in a well-balanced manner in the rear direction and the vertical direction by the impact, so that the deformation (twisting) when the impact is applied is more effectively suppressed, and the elastic deformation portion can be prevented from being displaced from the wearer's face.
Further, when the protective eyeglasses of the present invention are worn, the elastically deformable portion 5 of the rear frame 2 can be deformed to a size corresponding to the face width of the wearer so as to be suitable for the face width of the wearer.
In the protective eyewear of the present invention, since the water reservoir 8 is formed in the center of the upper edge 2a of the rear frame 2 and the water drain hole D is formed in the water reservoir 8 to the outside of the lens 3, sweat flowing down from the forehead during sports or the like, rain water flowing down from the forehead due to wearing in rainy weather, and the like accumulate in the water reservoir 8 and drain out of the water drain hole D, and thus, entry into the eyes of the wearer can be prevented.
In the protective eyewear of the present invention, the vent hole V to the inside of the lens 3 is provided in the upper side portion 1a and the lower side portion 1b of the front frame 1, and the vertical through hole Ha and the horizontal through hole Hb of the elastic deformation portion 5 are to the inside of the lens 3, so that the air permeability is improved, and fogging of the lens 3 can be reduced.
