Each eyecup 20 includes Ri Contact is formed of a rigid plastic material or flexible plastic material such as polycarbonate, the lenses 25, and a frame 26 extending annular rearwardly from the outer peripheral edge of the lens 25. The frame 26 includes an upper side wall portion 61 extending rearward from the upper end edge of the lens 25, a lower side wall portion 62 extending rearward from the lower end edge of the lens 25, and both side wall portions 63 extending rearward from the outer edge of the lens 25. Have. Further, the frame 26 extends radially outward from the lens 25 toward the rear, and the outer surfaces of the upper wall portion 61 and the lower wall portion 62 have a downwardly inclined shape. The inner portion 23 of the eyecup 20, projecting from the inner edge of the lens 25, connecting portion 27 having a through hole 27a is you position. The outer portion 24 of the A Ikappu 20, insertion portion 28 for connecting the ends of the head strap 40 which extends further rearward from the side wall portion 63 of the frame 26 is located. Further, the lens 25 and the frame 26 of the eye cup 20 may be formed from different members and combined, or the lens 25 may be subjected to mirror surface treatment.

  The head strap 40 and the gasket 30 are formed of a relatively soft material having flexibility, for example, a soft plastic material having softness and elasticity such as polyurethane. The nose bridge 50 is formed of a hard plastic material or a soft plastic material having flexibility, and is curved along the nose of the wearer, and has protrusions 51 at both ends. The inner portions 23 of the pair of eye cups 20 are connected to each other by the projections 51 positioned at both ends of the nose bridge 50 being fitted into the through holes 27a of the connecting portions 27 positioned at the inner portions 23 of the pair of eye cups 20. Is done.

The gasket 30 includes an annular front wall 31 fitted in the inner annular wall portion 29 Ru extending rearward from the rear surface of the lens 25, and a rear wall portion 32 extending from the front wall 31 to the rear and radially outward Have. The rear edge of the rear wall portion 32 extends in a flange shape so as to be in close contact with the face of the wearer. The front end portion of the front wall portion 31 is sandwiched between the frame 26 and the inner annular peripheral wall portion 29 in the circumferential direction. The gasket 30 may be integrally joined to the frame 26 of the eye cup 20 by an adhesive or a known heat welding means, or may be formed integrally with the frame 26 instead of being separated.

Referring to FIGS. 1, 4 and 5, the upper wall portion 61 of the frame 26, a flow path 70 extending in the circumferential direction are positioned. The flow path 70 is a concave groove and extends to an inner end 70 a located near the base end of the connecting portion 27 of the inner side portion 23 of the eye cup 20, and an outer end extending to the vicinity of the boundary between the upper side wall portion 61 and the side wall portion 63 70b. The flow path 70 is defined by inner and outer ends 70 a and 70 b, a first wall 26 a located on the front end side of the frame 26, and a second wall 26 b located on the rear end side of the frame 26, and the upper wall portion 61. is from being formed in an arc inclined surface rising gradient rearward, the second wall 26b is RyuIzuru radially outward than the first wall 26a.

Usually, in swimming goggles for swimming, etc., resistance of water due to turbulent flow is suppressed in water by making the outer surface of the frame as small as possible and preferably having a streamline shape. However, in a triathlon competition or the like, it is necessary to raise the face from the water to the surface many times and visually check the target in order to confirm the target while swimming. In such a case, when the wearer gets out of the water, the water remaining on the upper side of the eyecup flows to the lens surface and the visibility is deteriorated by the water film, so that the position of the target cannot be accurately grasped. There is. Further, in another athletics, visibility is deteriorated by rainwater dropped on the goggles to flow to the lens, sometimes interfere with the competition.

In the goggles 10 according to the present embodiment, the flow path 70 extending in the circumferential direction is provided in the upper side wall portion 61 of the frame 26, so that water positioned above the goggles 10 flows along the flow path 70 with the lens 25. flows toward both outer and / or one side thereof, the lens 25 is Ru can be inhibited from getting wet in water. To maintain a good view of the lenses 25, the position approximately 70% to 95% of the amount of the cross-sectional shape and size to flow to the outside of the lens 25 along the channel 70 of the water on top of the goggles 10 It is preferable to be designed .

More, in order to suppress the flow of water to the lens 25, it is preferable that the flow path 70 extends along the entire upper edge of at least the lens 25, causes the flow of water that has flowed into the flow path 70 downward Therefore, it is preferable that the outer end 70 b of the flow path 70 extends to the outer edge of the lens 25 and extends to the side wall portion 63 of the frame 26. The width dimension (dimension in the front-rear direction X) W1 of the flow path 70 can be adjusted as appropriate according to the width dimension of the upper side wall portion 61. However, in order to cause a required amount of water to flow , at least about 1.5 mm. It is above, Preferably it exists in the range of about 1.5-3.5 mm. Furthermore, the flow path 70 is preferably as close to the upper edge (or outer peripheral edge) of the lens 25 as possible in order to reduce the amount of water located thereon by reducing the surface area of the first wall 26a. Specifically, the separation dimension R1 between the flow path 70 and the upper edge 25a (or outer peripheral edge) of the lens 25 is at least about 1.0 mm or more, and preferably within a range of about 1.0 to 3.0 mm. It is in. When the separation dimension R1 is 1.0 mm or less, the area of the first wall 26a is relatively small, and the amount of water flowing on the lens 25 positioned on the first wall 26a can be minimized. The thickness dimension of 26a becomes too small and may be damaged during use. On the other hand, when the separation dimension R1 is 3.0 mm or more, the first wall 26a has a certain thickness because it has a required thickness dimension, but its area becomes relatively large, Therefore, the amount of water flowing to the lens increases and the lens 25 gets wet with water and the field of view may decrease.

In the present embodiment, the outer surface of the upper wall portion 61 of the frame 26 and the gasket 30 is formed in an arc-shaped inclined surface that is inclined downward , so that water positioned on the first wall 26 a flows to the lens 25. Therefore, by forming the outer surface of the first wall 26a in a flat shape or an arc-shaped inclined surface that is inclined downward, the flow of water to the lens 25 is suppressed, and water flows into the flow path 70. It can also be made easier. Further, the outer surface of the second wall 26b is also formed in an arc-shaped inclined surface that is inclined downward in the forward direction similarly to the first wall 26a, but by having such a shape, water located on the second wall 26b is allowed to flow. It is easy to flow into the flow path 70 located in front. The lens 25 is circularly-shaped, or may be any known shape such as elliptical circular or rectangular.

Referring again to FIG. 4, between the rear wall portion 32 of the frame 26 and the gasket 30, the front wall portion 31 having a smaller outer dimension than their by position, the step 35 is formed . Therefore, the water located above the goggles 10, particularly the water located above the gasket 30, flows downward along the step 35. Therefore, the level difference 35 can function as a second flow path for allowing water located above the goggles 10 to flow downward without flowing forward, together with the flow path 70 provided in the frame 26.

As described above, the flow path 70 allows the dropped water, such as water or rain water, located above the goggles 10 to flow to the lens 25 when the wearer raises his face from the water onto the water surface. it is for inhibiting, in addition to the concave groove which is recessed in the frame 26 may be a circumferential groove formed between the ribs of two rows protruding from the frame 26. Further, the flow path 70 may extend continuously or discontinuously in the circumferential direction of the frame 26, and the depth dimension D1 thereof is partially increased or partially narrowed or widened. Also good. Furthermore, a plurality of concave grooves extending in the circumferential direction in parallel in the upper side wall portion 61 may be used, and the cross-sectional shape extends sharply downward in order to prevent the inflowing water from leaking outside. It may be.

<Modification 1>
Referring to FIGS. 6 and 7, in this modification, the flow path 80 formed of a concave groove extends from the upper wall portion 61 of the frame 26 to the side wall portion 63, and further extends continuously to the lower wall portion 62. ing. The inner end 80 a of the flow path 80 is located on the upper wall portion 61, and the outer end 80 b is located on the lower wall portion 62. Since the flow path 80 continuously extends along the peripheral edge excluding the inner edge of the lens 25 in this manner, the water positioned on the upper side of the eyecup 20 can be more reliably guided downward or rearward. In addition to continuously extending from the upper side wall 61 to the lower side wall 62, the flow path 80 may extend discontinuously. For example, the flow path 80 may be provided on the upper and lower side walls 61, 62 and the side wall 63, respectively. It may be formed from three positioned parts, or may be formed from two or more parts.

<Modification 2>
Referring to FIG. 8, in the present modification, the flow path 90 includes a first portion 81 extending rearward from the upper wall portion 61 toward the side wall portion 63, and a lower wall portion from an intersection 83 of the first portion 81. And a second portion 82 that gradually extends forward as it goes to 62. The channel 80 has a bifurcated shape (or a substantially V shape) that becomes narrower from the front to the rear in a side view of the goggles 10, and the first portion 81 and the second portion 82 in the side wall portion 63. At the intersection 83 with the outermost peripheral edge of the lens 25.

Since the flow path 80 continuously extends from the upper wall portion 61 to the side wall portion 63, the water located on the upper side of the eye cup 20 can be more reliably guided downward or rearward. Further, the flow path 80 extends rearward so as to move away from the lens 25 as it goes from the upper side wall portion 61 toward the side wall portion 63 without being along the periphery of the lens 25, so that the water flowing through the flow path 80 is in the lens 25. it can be more effectively prevented from flowing to. The flow path 80 may be curved in the vicinity of the intersection 83 without being sharp, and the first portion 81 and the second portion 82 may be separated without having the intersection 83. Furthermore, the entire flow path 80 may extend backward in a convex shape, or may have a trifurcated shape or a quadrant shape.

<Modification 3>
Referring to FIG. 9, in this modification, the flow path 95 extends from the upper wall portion 61 of the frame 26 through the side wall portion 63 to the lower wall portion 62, and the side wall portion 63 includes upper and lower side walls. A wide portion 96 is formed which is wider than the portions located in the portions 61 and 62. The side wall portion 63, by forming such a wide portion 96, can be wearer in a state such that the oblique head, water located in the side wall portion 63 can be inhibited from flowing toward the lens .

In the present invention, the goggles 10 including the goggle main body having the pair of eye cups 20 and the pair of gaskets 30 have been described, but the eye cups 20 are directly brought into contact with the face without the gasket 30. Alternatively, the eye cup 20 may not be a separate body connected via the nose bridge 50 but may be integrally formed. The characteristic configuration of the present invention can be used in various goggles that are worn when activities are required in the outdoors, in addition to sports competitions such as triathlons, as long as the technical effects described above are produced.
