[0021] 以下，對於實施本發明的保護眼鏡用的形態，依據圖面詳細說明。 　　[0022] 本發明的保護眼鏡，是如第1～5圖所示，將硬質的前框架1及軟質的後框架2一體化者，在前框架1中具備透鏡3，在後框架2中具備頭束帶4，將此後框架2的周圍密合於使用者的臉部。圖示者，將兩者別體作成後，雖是由嵌合而一體化，但是由融接或黏著而一體化也可以。且，藉由硬質合成樹脂及軟質合成樹脂的雙重射出同時成形而一體化也可以。 　　[0023] 前框架1，是由硬質的合成樹脂等所構成，將透鏡3的周圍包圍將透鏡3密合保持。在此前框架1的上邊部1a及下邊部1b中，設有朝透鏡3的內方貫通的通氣孔V。在設置這種通氣孔V時，如圖示，藉由將設置通氣孔V的部分的前框架1很厚地形成，就容易設置通氣孔V。又，在本發明中，硬質雖是與後框架2的軟質相比相對地硬質即可，但是將前框架1的蕭氏硬度設成90以上的話，在強度面較佳。 　　[0024] 後框架2，是由軟質的合成樹脂等所構成，將其接觸面沿著使用者的額和眼的周邊、鼻背等的形狀形成，容易與使用者的臉部密合。且，將此後框架2從前框架1的兩端延設的彈性變形部5，在此彈性變形部5的前側端突設頭束帶安裝部6，並且在彈性變形部5的後側端延設眼鏡腳接觸部7。進一步，在後框架2的上邊部2a中央，形成有水滯留部8，在此水滯留部8的底，形成有朝透鏡3的外方貫通的排水孔D。又，在本發明中，軟質是蕭氏硬度為60以下者，在本發明中，雖可以將後框架2的蕭氏硬度設成30～60，但是45～55較佳。藉由設成這種蕭氏硬度，使用者的臉部成為非常容易地密合於後框架2。 　　[0025] 透鏡3，是由硬質的玻璃或合成樹脂所構成，圖示雖是雙眼透鏡，但是單眼透鏡也可以。又，在本發明中，透鏡3，雖是具備較佳，但是即使不具備也可以。 　　[0026] 頭束帶4，是由橡膠或合成樹脂等的彈性構件所構成，藉由長度可調節自如地被安裝於後框架2兩端的頭束帶安裝部6，將此頭束帶4旋緊或鬆緩，而貼合於使用者的頭周圍。 　　[0027] 彈性變形部5，是如第8、9圖所示，透過縱拔孔Ha分離成前側變形部9及後側變形部10，進一步前側變形部9是作成厚板狀，後側變形部10，是透過橫拔孔Hb分離成上桿部10a及下桿部10b。且，彈性變形部5的縱拔孔Ha及橫拔孔Hb，是朝透鏡3的內方貫通。進一步，如第8圖所示，將前側變形部9的縱剖面A及後側變形部10的縱剖面B的面積比設成1：4～5，將上桿部10a的縱剖面Bu及下桿部10b的縱剖面Bd的面積比設成1：0.8～1.2。因為藉由設成這種面積比，可取得彈性變形部5的前後方向及上下方向的變形度的平衡，所以衝突時的保護眼鏡的變形（扭轉）可更有效地被抑制。 　　[0028] 頭束帶安裝部6，是由硬質的合成樹脂等所構成，如第5圖所示，從外側橫跨內側形成了二個縱長開縫孔6a、6b。且，將頭束帶4安裝於此頭束帶安裝部6時，使頭束帶4的一端部從內側的縱長開縫孔6b的背側朝表側通過，使此頭束帶4的一端部從外側的縱長開縫孔6a的表側朝背側通過，朝頭束帶安裝部6的外側突出。又，頭束帶安裝部6，是頭束帶4的長度可調節自如地被安裝即可，其構造不特別限定。 　　[0029] 眼鏡腳接觸部7，是與後框架2相同由軟質的合成樹脂等所構成，形成近似舌頭狀，在表側中在寬度方向形成多數的肋7a容易朝外側方向彎曲，背側是作成平滑面而容易與使用者的眼鏡腳密合。 　　[0030] 進一步，頭束帶安裝部6及眼鏡腳接觸部7，是如第5圖所示，藉由將與保護眼鏡的正面的傾斜角α、β皆設成90～100度，並且將兩傾斜角α、β設成幾乎等同，而將頭束帶安裝部6及眼鏡腳接觸部7幾乎平行地配置。如此的話，因為藉由頭束帶4的旋緊而使頭束帶安裝部6的傾斜角α比此角度更小，所以力是朝使眼鏡腳接觸部7的傾斜角β也比此角度小的方向作用，使眼鏡腳接觸部7與使用者的眼鏡腳更強力地密合。 　　[0031] 將如此構成的本發明的保護眼鏡穿戴的話，軟質的後框架2整體因為是與著用者的臉部密合，所以在球技和冬季運動的比賽等，即使受到由球等的飛來物或對人、對物衝突所產生的衝擊，仍可以將該衝擊更有效地吸收、緩和，更完全地保護眼。又，圖示的實施品，是在由American Society for Testing Materials.（ASTM International：美國材料試驗協會）所制定的規格中的ASTM F803-11的由壁球的球所產生的高速衝擊試驗合格。 　　[0032] 進一步，本發明的保護眼鏡，因為是藉由前述衝擊使後框架2的彈性變形部5朝後方向及上下方向平衡佳地變形，使受到衝擊時的變形（扭轉）被有效地抑制，所以可以防止從使用者的臉偏離。 　　[0033] 且將本發明的保護眼鏡穿戴的話，後框架2的彈性變形部5是變形成使用者的臉寬度的尺寸，可以適用於該使用者的臉寬度。 　　[0034] 進一步，本發明的保護眼鏡，因為是在後框架2的上邊部2a中央，形成有設有朝透鏡3的外方貫通的排水孔D的水滯留部8，所以在運動等的比賽從額流下的汗、和雨天時等的穿戴而從額流下的雨水等，因為是在此水滯留部8滯留並從排水孔D被排出，所以可以防止進入使用者的眼。 　　[0035] 且本發明的保護眼鏡，因為是在前框架1的上邊部1a及下邊部1b設有朝透鏡3的內方貫通的通氣孔V，彈性變形部5的縱拔孔Ha及橫拔孔Hb是朝透鏡3的內方貫通，所以通氣性良好，可以減少透鏡3的起霧。[0021] Hereinafter, the form of the protective glasses for implementing the present invention will be described in detail based on the drawings. [0022] The protective glasses of the present invention, as shown in FIGS. 1 to 5, are a combination of a hard front frame 1 and a soft rear frame 2. The front frame 1 includes a lens 3 and the rear frame 2 includes The headband 4 tightly fits the periphery of the rear frame 2 to the user's face. As shown in the figure, after the two bodies are made, they are integrated by fitting, but they may be integrated by fusion or adhesion. In addition, it may be integrated by simultaneous molding by dual injection of hard synthetic resin and soft synthetic resin.　　[0023] The front frame 1 is made of hard synthetic resin or the like, and surrounds the lens 3 to hold the lens 3 in close contact. The upper side portion 1a and the lower side portion 1b of the front frame 1 are provided with vent holes V penetrating inward of the lens 3. When such a vent hole V is provided, as shown in the figure, the vent hole V can be easily provided by forming the front frame 1 at the portion where the vent hole V is provided thickly. In addition, in the present invention, the hardness may be relatively harder than the softness of the rear frame 2, but if the Shore hardness of the front frame 1 is set to 90 or more, it is better in terms of strength.　　[0024] The rear frame 2 is made of soft synthetic resin and the like, and its contact surface is formed along the shape of the user's forehead and eyes, the back of the nose, etc., so that it can easily fit with the user's face. And, this rear frame 2 is extended from the elastic deformation part 5 of the front frame 1 at the front end of the elastic deformation part 5, the head strap mounting part 6 is protruding, and the elastic deformation part 5 is extended at the rear end The temple contact part 7. Furthermore, in the center of the upper side portion 2 a of the rear frame 2, a water retention portion 8 is formed. At the bottom of the water retention portion 8, a drainage hole D penetrating to the outside of the lens 3 is formed. Furthermore, in the present invention, the softness is one having a Shore hardness of 60 or less. In the present invention, although the Shore hardness of the rear frame 2 can be set to 30-60, 45-55 is preferable. By setting it to this Shore hardness, the user's face becomes very easily close to the rear frame 2.　　[0025] The lens 3 is made of hard glass or synthetic resin. Although the figure shows a binocular lens, a single eye lens is also acceptable. In addition, in the present invention, although the lens 3 is preferably provided, it may not be provided. [0026] The head strap 4 is composed of an elastic member such as rubber or synthetic resin, and the head strap 4 is twisted by the head strap mounting portions 6 which are adjustable in length and mounted on both ends of the rear frame 2. Tight or loose, and fit around the user's head. [0027] The elastic deformation portion 5 is as shown in Figures 8 and 9, separated by the longitudinal drawing hole Ha into a front side deformation portion 9 and a rear side deformation portion 10. Further, the front side deformation portion 9 is formed into a thick plate shape, and the rear side deforms The part 10 is separated into an upper rod part 10a and a lower rod part 10b through a horizontal drawing hole Hb. In addition, the vertical drawing hole Ha and the horizontal drawing hole Hb of the elastic deformation portion 5 penetrate inward of the lens 3. Further, as shown in Figure 8, the area ratio of the longitudinal section A of the front deforming portion 9 and the longitudinal section B of the rear deforming portion 10 is set to 1:4 to 5, and the longitudinal section Bu of the upper rod portion 10a and the lower The area ratio of the longitudinal section Bd of the rod portion 10b is set to 1:0.8 to 1.2. By setting such an area ratio, it is possible to balance the degree of deformation of the elastic deformation portion 5 in the front-rear direction and the vertical direction, so that the deformation (torsion) of the protective glasses during collision can be more effectively suppressed.　　[0028] The headband attachment portion 6 is made of hard synthetic resin or the like. As shown in Fig. 5, two longitudinally long slit holes 6a and 6b are formed across the inside from the outside. When the headband 4 is attached to the headband attachment portion 6, one end of the headband 4 is passed from the back side of the inner longitudinal slit hole 6b toward the front side, so that one end of the headband 4 The part passes from the front side to the back side of the longitudinally long slit hole 6 a on the outside, and protrudes to the outside of the headband attachment part 6. In addition, the headband attachment portion 6 may be attached so that the length of the headband 4 can be adjusted freely, and its structure is not particularly limited. [0029] The temple contact portion 7 is made of soft synthetic resin and the like like the rear frame 2, and is shaped like a tongue. On the front side, a large number of ribs 7a formed in the width direction are easily bent in the outer direction, and the back side is made The smooth surface makes it easy to fit the user's temple. [0030] Furthermore, the headband mounting portion 6 and the temple contact portion 7 are as shown in FIG. 5, by setting the inclination angles α and β to the front of the protective glasses to 90 to 100 degrees, and The two inclination angles α and β are set to be almost equal, and the headband attachment portion 6 and the temple contact portion 7 are arranged almost in parallel. In this case, because the inclination angle α of the head strap mounting portion 6 is smaller than this angle by the tightening of the head strap 4, the force is to make the inclination angle β of the temple contact portion 7 also smaller than this angle. The directional action of, makes the eyeglass foot contact portion 7 and the user’s eyeglasses more strongly adhere. [0031] When the protective glasses of the present invention constructed in this way are worn, the soft rear frame 2 as a whole is in close contact with the user’s face. Therefore, even if it is hit by a ball or the like in games such as soccer skills and winter sports, The impact of incoming objects or conflicts between people and objects can still absorb and alleviate the impact more effectively, and protect the eyes more completely. In addition, the implemented product shown in the figure passed the high-speed impact test of the squash ball of ASTM F803-11 in the specifications established by the American Society for Testing Materials. (ASTM International: American Society for Testing and Materials). [0032] Furthermore, in the protective glasses of the present invention, because the elastic deformation portion 5 of the rear frame 2 is deformed in the rear direction and the up and down direction by the aforementioned impact, the deformation (torsion) upon impact is effectively suppressed. , So it can prevent deviation from the user's face.　　[0033] When the protective glasses of the present invention are worn, the elastic deformation portion 5 of the rear frame 2 is deformed into the width of the user's face, and can be adapted to the width of the user's face. [0034] Furthermore, the protective glasses of the present invention are formed in the center of the upper side portion 2a of the rear frame 2 with a water retention portion 8 provided with a drain hole D penetrating the outside of the lens 3. Sweat from the forehead, rainwater from the forehead when worn on a rainy day, etc., are retained in the water retention portion 8 and discharged from the drainage hole D, so that it can be prevented from entering the eyes of the user. [0035] In addition, the protective glasses of the present invention are provided in the upper side portion 1a and the lower side portion 1b of the front frame 1 with a vent hole V penetrating inward of the lens 3, a vertical drawing hole Ha and a horizontal drawing hole of the elastic deformable portion 5. The hole Hb penetrates toward the inside of the lens 3, so the air permeability is good, and the fogging of the lens 3 can be reduced.
