Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to so-called sports goggles that are worn on the face by swimmers, skiers, motorcycle riders, etc. to protect their eyes.

(Prior Art and Problems to be Solved by the Invention) Conventionally, goggles of this type, especially swimming goggles that are commonly used in practical use, consist of a pair of lens frames whose lens parts are integrally formed from plastic. The laterally opposing inner parts are connected by a nose belt. However, in this known goggle, the nose belt does not have shape-retaining properties and does not have the function of integrally holding the lens frame while maintaining a given distance therebetween. When worn on the face, the lens frame cannot be stably fixed to a predetermined part of the face. Therefore, the goggles may become misaligned or become loosely worn, and it is troublesome to frequently correct the worn state.

The main object of the present invention is to preferably mold a nose pad connecting member made of a soft material, which fits and abuts this part on both sides of the nose in a sandwiched state, in place of the nose belt, and to attach the nose pad connecting member in a lateral direction of the pair of lens frames. It is an object of the present invention to provide sports goggles which can eliminate the above-mentioned drawbacks by integrally and removably connecting an inner side facing the lens frame and detachably attaching a shape-retaining frame to the lens frame.

(Means for Solving the Problems) The goggles of the present invention for achieving the above objects include:
It includes a pair of transparent lens frame members integrally formed with lenses, a nose pad connecting member, and a shape-retaining frame member. Both of the lens frame members have a first fitting part on the inner side facing each other in the lateral direction, a second fitting part on the outer side facing the first fitting part in the lateral direction, and the second fitting part on the outside side facing the first fitting part in the lateral direction. It has a belt hooking part on the outside of the fitting part, and is curved toward the front side. The nose pad connecting member has a third fitting portion that can be fitted into and removed from the first fitting portion on the outside opposite to the nose pad connecting member in the lateral direction. The shape-retaining frame member is
The lens frame member has a rod portion formed with a groove that fits into the upper edges of both lens frame members, and a leg portion that protrudes downward from both lengthwise ends of the rod portion and can be fitted into and removed from the second fitting portion. and is curved toward the front.

In a preferred embodiment, the first fitting portion is a first groove extending from an upper end to near a lower end of the first fitting portion, and the third fitting portion is provided in the first groove. It is a protrusion that can be inserted and fitted from the upper end, the second fitting part is a second groove, and at least a part of the leg part of the shape-retaining frame member has a shape that can be inserted and fitted into the second groove. The nose pad connecting member has a bridge portion and a clamping portion that extends downward from both sides of the bridge portion and gradually expands, and both lens frame members are attached to the upper edge of the bridge portion. 1st
The shape-retaining frame member is engaged with the first locking portion in the groove of the rod portion of the shape-retaining frame member, and the shape-retaining frame member and the shape-retaining frame member are engaged with the first engaging portion. It has a second locking part that maintains the fitting with the rod part of the frame member, and both the lens frame members have a first locking part between the second groove and the belt locking part. a belt insertion hole; the shape-retaining frame member has a second belt insertion hole in the leg portion that overlaps with the first belt insertion hole; the first and second belt insertion holes; A belt is inserted through the belt, and the belt is inserted through and hooked into the belt hooking portion, and both lens frame members are made of a rigid material, the nose pad connecting member is made of an elastic material, and the shape-retaining frame member is made of a rigid material. are each molded from a flexible material.

(Operations and Effects) The goggles of the present invention having the above configuration have a structure that can be assembled and disassembled by the pair of lens frame members, the nose pad connecting member, and the shape-retaining frame member. In this assembly, the third fitting portion of the nose pad connecting member is inserted into the first groove of the first fitting portion of both the lens frame members.
Insert the protrusion into the fitting part of the frame member, and connect the groove of the rod part of the shape-retaining frame member (the second locking part) to the upper edge of both lens frame members (the first locking part). This is done by fitting the legs of the shape-retaining frame member into the second fitting portions (the second grooves) of both lens frame members. Since it has the above-mentioned insertion structure, the above-mentioned assembly and disassembly are extremely easy.

In this manner, by assembling the shape-retaining frame member to both the lens frame members, the lens frame members, the nose pad connecting member, and the shape-retaining frame are integrally connected, and the entire goggle is attached to the wearer's face. It maintains a form that conforms to the abutment. This holding function is sufficient when the nose pad connecting member is molded from an elastic material that is very soft compared to both the lens frame members and the shape-retaining frame member in order to fit the nose of the wearer. It is demonstrated in Therefore, the goggles are stably fixed to the face and will not shift or become loose while being worn.

The nose pad connecting member is molded from the elastic material and is formed of the bridge portion and both the clamping portions that gradually expand downward, so that the nose pad connecting member can adapt to the size of the wearer's nose. The goggles fit stably and softly depending on the size and shape, and do not cause pain to the wearer's nose even if the goggles are worn for a relatively long period of time.

As mentioned above, both the lens frame members;
By providing a structure in which the nose pad connecting member and the shape-retaining frame member can be assembled and disassembled, different colors can be given to each of the goggles, thereby enhancing the aesthetic appearance and sense of taste of the goggles. Moreover, for example, if one assembled pair of goggles is sold with one or more nose pad connecting members in different colors, the wearer can disassemble the goggles and replace them with the desired nose pad connecting member. can.

When the shape-retaining frame member is assembled to both lens frame members, the coupling and integration between both lens frame members and the nose pad connecting member is strengthened. By inserting a belt into the second belt insertion hole of the shape-retaining frame member, both the lens frame members and the shape-retaining frame member are integrated, and by extension, they are connected to the nose pad connecting member. Bonding and integration are more reliably guaranteed.

(Example) Referring to the drawings, an example of the present invention will be described below using swimming goggles as an example. In addition, in the explanation, terms in parentheses indicate terms in the claims.

As shown in FIGS. 1 and 4, the swimming goggles include a pair of bilaterally symmetrical lens frame members 12 integrally formed with a lens portion 11, and a pair of lens frame members 12 that are fitted into laterally opposing inner sides of both lens frame members. a nose pad connecting member 13 that connects these together;
It includes a shape-retaining frame member 14 that fits into the upper edges and outer portions of both lens frame members and the upper edge of the nose pad connecting member and integrally connects them.

The pair of lens frame members 12 are made of transparent hard plastic and have rigidity. Both lens frame members 12 are generally gently curved toward the front side so that the back surfaces of both lens frame members fit against the wearer's face, and the inner sides of both lens frame members that face each other in the lateral direction are curved as a whole. A fitting groove (first fitting part or first groove) 15 having an open end on the upper surface of the part, a closed bottom face facing downward from the open end, and a T-shaped cross section.
and a fitting groove (second fitting portion or second groove) 16 having a V-shaped cross section on the front surface of the outer side of both lens frame members, which faces the fitting groove in the lateral direction. There is. Further, both lens frame members 12 have locking claws (first locking portions) 17 spaced apart laterally on the front surfaces of the upper sides of both lens frame members, and a belt is inserted into the outer side of the fitting groove 16. It has a hole (first level insertion hole) 18 and a belt hook portion 19 extending from the outer edge of the insertion hole. A pad member 20, which has a sponge-like soft elasticity and comes into watertight pressure contact with the face, is integrally bonded to the outer periphery of the back surface of both lens frame members 12.

The nose pad connecting member 13 is made of soft plastic or natural or synthetic rubber and has elasticity. The nose pad connecting member 13 includes a bridge section 21, a clamping section 22 extending downward from both sides of the bridge section, and an opening in the fitting groove 15 formed on the outside of both clamping sections. It has a fitting protrusion (third fitting part) 23 with a T-shaped cross section that is inserted and fitted from the end. Further, the nose pad connecting member 13 has a flange 24 on the inner periphery of both the clamping parts 22 that slopes outward. Nose pad connecting member 13
is so shaped that it fits snugly against the wearer's nose. If the size of the nose is larger than the spacing between the two clamping parts 22, the two clamping parts expand outward and come into contact with each other in a similar manner.

The shape-retaining frame member 14 is made of plastic or synthetic rubber, which is soft but slightly harder than the nose pad connecting member 13, and has flexibility or bendability. The shape-retaining frame member 14 is
The overall shape is gently curved toward the front side to follow the contours of the wearer's face, and the cross section opening on the back side is approximately U-shaped.
