Description

  The present invention relates to a swimming goggles suitable for a swimming goggles wearer to wear.

  Conventionally, it has a pair of lenses and a headband connected by a nose belt, and after both ends of the headband are passed through the through holes formed in the frames of the lenses, the direction is reversed. Swimming goggles that are fixed at a required length position are well known. For example, in the underwater spectacles disclosed in Japanese Patent Application Laid-Open No. 2002-45439 (Patent Document 1), a longitudinal end portion of a headband extending from rear to front is hung around an outer end portion of a frame, and the end portion is rearward. A through-hole extending in the front-rear direction for passing the headband is formed inside the hook in the width direction of the underwater glasses. In the worn underwater glasses, the through hole opens toward the front of the frame, that is, toward the front of the face of the wearer of the swimming goggles.

Further, the goggles disclosed in Japanese Patent Laid-Open No. 2003-236018 (Patent Document 2) have a through hole extending in the front-rear direction at the outer end portion of the frame, and the end of the headband passed through the through hole is It is bent and reversed by a through hole formed in a band connector separate from the frame, and passed through the through hole of the frame again. The band connector can enter the through-hole of the frame from the front of the frame and close the through-hole.
JP 2002-45439 A JP 2003-236018 A

  In the underwater glasses described in Patent Document 1, when wearing this, the through hole for passing the headband opens forward and the shape near the through hole is not smooth. The flow of water from the front to the back of the wearer may be disturbed in the vicinity of the through-hole and act to increase resistance to advancement.

  In the goggles described in Patent Document 2, the through hole in the outer end portion of the frame is closed by the band connector, and the shape near the through hole becomes smooth. However, to attach the headband with this goggles, pass the end of the headband through the through-hole, and further pass through the through-hole formed in the band connector to reverse the direction of the end of the headband. Later, the end must pass through the through-hole of the frame again. Thus, in this goggles, it takes time and effort to pass the end of the headband through the two through holes.

  In this invention, in the swimming goggles having a through hole extending in the front-rear direction for passing the headband to the outer end portion of the frame, the flow of water from the front to the rear of the wearer is disturbed in the vicinity of the through hole. Therefore, it is an object of the present invention to make an improvement so that the mounting of the headband through the through hole does not take time.

  In order to solve the above-described problems, the present invention is directed to a vertical vertical direction, a horizontal width direction, and both directions corresponding to a vertical direction, a width direction, and a front-rear direction of a swimming goggles wearer's face A swimming goggle comprising a pair of lenses arranged in the width direction via a nose belt and a headband hung around the head of the swimming goggles wearer.

  In the swimming goggles, the present invention is characterized as follows. Each of the lenses has a frame extending annularly along the periphery of the lens, and the frame bisects the interval in the width direction between the lenses and is orthogonal to the width direction. An outer end portion located near the center plane extending in the up-down direction and the front-rear direction and connected to the nose belt, and an outer end portion located on the opposite side of the inner end portion in the width direction; The portion includes a hanging portion capable of turning one of both end portions in the length direction of the headband from the rear in the front-rear direction and reversing the direction of the end portion, and a portion of the periphery by the hanging portion. And a through hole through which the headband can be passed. The frame is further provided with a shielding portion that is spaced forward from the through hole and covers the through hole. The shielding portion is formed with a front surface facing the front side and a rear surface opposite to the front surface, and the center of the rear surface facing the through hole is formed from the front toward the rear. An inclined surface extending so as to approach the surface is formed.

  In a preferred embodiment of the present invention according to claim 2, the shielding portion is formed to have a substantially uniform thickness between the front surface and the rear surface, and the inclined surface extends from the rear surface to the rear side. It is provided in the rib formed so that it may take out.

  In a preferred embodiment of the present invention according to claim 3, the shielding portion is attached to the frame via an annular portion that is fitted to the frame from the outside.

  In a preferred embodiment of the present invention according to claim 4, the annular portions fitted to the frame of each of the lenses are formed integrally with the nose belt.

  According to the first aspect of the present invention, in the swimming goggles, the through hole formed in the outer end portion of the frame and extending in the front-rear direction is covered in front by the shielding member. The water flow from the rear to the rear proceeds along the outer surface of the shielding member and does not enter the through hole, and the water flow is disturbed in the vicinity of the through hole, thereby increasing the water resistance against the wearer of the swimming goggles. There is no such thing. In addition, in this swimming goggles, when the end of the headband is passed through the through hole in the outer end portion of the frame from the rear, the end that comes out in front of the through hole hits an inclined surface formed on the shielding member and is bent. Since it goes out of the shielding member in the width direction of the swimming goggles, the direction of the end can be easily reversed and passed through the through hole again by picking the end that goes out.

  According to the embodiment of the present invention according to claim 2, it is possible to make the shielding part thin by forming the rib on the shielding part and providing the rib with an inclined surface.

  According to the embodiment of the present invention according to claim 3, the shielding portion can be attached to the swimming goggles by fitting the annular portion of the shielding portion to the frame from the outside.

  According to the embodiment of the present invention according to claim 4, since the annular portions of the shielding portion are integrally formed so as to be connected to each other via the nose belt, the manufacturing process of the swimming goggles can be simplified. The decoration effect on swimming goggles can be changed in various ways.

  The details of the swimming goggles according to the present invention will be described with reference to the accompanying drawings.

  A swimming goggles 1 shown in a perspective view in FIG. 1 includes a pair of lenses 2, a frame 3 formed along an edge of each lens 2, a nose belt 4 connecting the pair of lenses 2, and a head Band 6. The nose belt 4 is formed in an annular shape so as to surround the lens 2, and is integrated with a pair of edge decorations 7 fixed to the frame 3. A shielding portion 8 extending rearward is formed. Such swimming goggles 1 have a vertical vertical direction A corresponding to the vertical direction, the width direction, and the front-rear direction of the wearer's face (not shown), a horizontal width direction B, and both of these directions A. , B and a front-rear direction C. In addition, a virtual plane D that divides the separation dimension in the width direction B of the pair of lenses 2 into two equal parts and extends in the vertical direction A and the front-rear direction C bisects the length of the nose belt 4.

  FIG. 2 is a PQRS arrow view of FIG. The lens 2 and the frame 3 are integrally formed of a transparent hard plastic, and the frame 3 has a substantially annular shape and extends rearward from the lens 2. The extended rear edge portion has an eye cup made of a flexible elastic material. 9 is attached. In the width direction B of the swimming goggles 1, the frame 3 has an inner end portion 11 positioned closest to the center plane D and an outer end portion 12 positioned farthest from the center plane D. The inner end portion 11 The proximal end portion 16 of the nose belt 4 enters the groove portion 13 formed in FIG. A through hole 17 is formed in the outer end portion 12 of the frame 3 so as to pass through the outer end portion 12 in the front-rear direction C. A part of the peripheral portion of the through hole 17 is used to hang the headband 6 around. The turning part 18 is formed. In addition, a stopper 19 that protrudes outward in the width direction B is formed in the hanging portion 18. Here, “outward” means a direction away from the center plane D in the width direction B, and the direction approaching the center plane D is inward. The nose belt 4, the edge decoration portion 7, and the shielding portion 8 are integrally formed of a flexible material such as soft polyethylene, nylon, plastic elastomer, and natural rubber, more preferably a flexible and elastic material, and is a shielding member. 21. The edge decoration portion 7 and the shielding portion 8 are fitted into a groove portion 13 formed on the peripheral surface of the frame 3 in the same manner as the nose belt 4, and the lens 2 has a circumferential direction and a front-rear direction C. It is fixed so that it will not move. In front of the through hole 17, the shielding portion 8 of the shielding member 21 is provided to cover the through hole 17. The shield 8 has a front surface 26 and a rear surface 27 (see FIG. 3), and the preferred front surface 26 is formed smoothly so as not to disturb the flow of water. The rear surface 27 has an inclined surface 28 extending from the front to the rear so as to approach the center surface D, and the tip portion 31 of the headband 6 is passed between the inclined surface 28 and the hooking portion 18. A possible clearance 29 is formed. The headband 6 is formed of a flexible elastic material, and a plurality of hole portions 32 through which the stopper 19 is passed are formed at both end portions 31 extending in the length direction.

  FIG. 3 is a partially enlarged view of FIG. 2, but the headband 6 is in the process of inserting the tip portion 31 into the through hole 17. As shown by the solid line, the tip portion 31 hits the inclined surface 28 of the shield 8 and elastically bends when inserted into the through hole 17 of the frame 3 from the rear to the front of the swimming goggles 1. Then, the swimming goggles 1 go out in the width direction B, that is, out of the frame 3. The front end portion 31 is picked and inverted so as to be directed rearward as indicated by an imaginary line, and then the length of the headband 6 is adjusted through the stopper 19 to an appropriate one of the plurality of holes 32. To do.

  FIG. 4 is a partially broken arrow view taken along line IV-IV in FIG. 3, but the headband 6 through the stopper 19 is indicated by a virtual line. The shielding portion 8 in the shielding member 21 has a substantially uniform thickness between the front surface 26 and the rear surface 27, and a rib 36 is formed at a portion where the rear surface 27 faces the through hole 17 so as to protrude rearward. An inclined surface 28 is formed on the rib 36. The shielding portion 8 can be made thick so that almost the entire rear surface 27 becomes the inclined surface 28. However, if a rib structure such as the illustrated example is used, the material for making the shielding portion 8 is reduced. Not only can the molding time be reduced when the shielding member 21 is manufactured by injection molding.

  The shielding member 21 formed in this way covers the through hole 17 formed behind the shielding portion 8 and the vicinity thereof, so that the flow of water from the front to the back during swimming allows the through hole 17 to flow. It is possible to prevent an increase in resistance when the swimming goggles wearer tries to move forward by being disturbed in the vicinity thereof. However, since the shielding portion 8 covering the through hole 17 has the inclined surface 28 on the rear surface 27, it is difficult to pass the tip portion 31 of the headband 6 through the through hole 17 due to the presence of the shielding portion 8. Absent. Further, the edge decoration portion 7 of the shielding member 21 not only enables the shielding portion 8 to be attached to the frame 3, but also cooperates with the nose belt 3 and the shielding portion 8 if the color and shape are appropriately selected. The decoration effect on the periphery of the lens 2 and the entire swimming goggles 1 can be changed in various ways. If the nose belt 4, the edge decoration 7 and the shielding part 8 are integrally molded as the shielding member 21, the manufacturing process of the swimming goggles 1 can be simplified as compared with the case where these parts are individually molded. it can.

  In the present invention, the lens 2 and the frame 3 which are integrally shown in the illustrated example can be replaced with different ones. Also, the nose belt 4 and the edge decoration 7 that are integrally formed can be separated, and the nose belt 4 can be made as a single member, and that member can be attached to each of the frames 3. The shielding portion 8 can be formed not to be a part of the shielding member 21 but to be integrated with the portion 12 at the outer end portion 12 of the frame 3. The length of the headband 6 is adjusted by passing the stopper 19 through the hole 32, but a buckle having an appropriate shape can be used for the headband 6 in place of the stopper 19 acting as such.

  According to the present invention, it is possible to manufacture swimming goggles that are easy to pass through the headband and that do not disturb the flow of water by the through holes for passing the headband.

The perspective view of swimming goggles. The PQRS line arrow figure of FIG. The elements on larger scale of FIG. FIG. 4 is a partially broken arrow view taken along line IV-IV in FIG. 3.
