Description Lightweight underwater glasses and eye patch plate used for them

[ Technical field 〕

INDUSTRIAL APPLICABILITY The present invention improves underwater spectacles, and more specifically, fits perfectly to the shape of the wearer's face, flexes and fits, and has excellent water-sealing properties underwater. In addition, the present invention relates to a lightweight underwater spectacle for aqua sports, which does not cause pain to the wearer by distributing the water pressure applied during diving evenly to the contact area of the eye, and has a sports-glass-like appearance.

[Background technology]

Under the current tide of aqua-sports (SCUBA: Self-Contained Underwater Breathing Apparatus) and aquatic sports such as diving, and the advent of an affluent society, where the assertion of individuality and good looks are required. Even if you pick up a piece of equipment that is used for a good play, it is not enough to simply fulfill the function, it is more comfortable to use and easier to use, and it can not be sold unless the design is smart It has become. The underwater glasses proposed by the present inventor are nothing but inventions that have been inspired by such social trends.

In other words, underwater spectacles that are generally marketed for underwater sports such as swimming and scuba diving have a view through the water. The so-called “underwater goggles” type, in which a band is attached to the eye by means of a band, so that the part between the face and the face can be sealed underwater, and an There is a binocular tube type in which two cylindrical members fitted with a plate are symmetrically connected to each other so as to correspond to the eye and can be worn by a band. However, in any case, since the rubber scart or the cylindrical member surrounding the eye part has an unusual appearance, it is hardly noticeable to go out into the city without wearing it.

From the above, the present inventor has come to the realization that it is necessary to have excellent underwater spectacles designed to be able to go out while wearing a good dress even in the city. However, in order to design the underwater glasses so that they can be worn in the city even when walking, it is necessary to make the shape of the front part of the underwater glasses close to that of ordinary sunglasses. Nevertheless, underwater glasses, of course, must be sealed in a watertight manner around the eyelids. It must be composed of a single plate, and it can be adapted to anyone's face, and it is necessary to take measures to remove pain that does not hurt the wearer even when the water pressure is high.

[Technical communication]

Therefore, according to the present invention, the front portion is a smart plate having a single shape, and the flat face wearer has a high degree of curvature. Water tightness that can flexibly adapt to any face shape even to thin-faced wearers, and has a nice front part like sunglasses, and does not allow water to enter the eyes. The technical issue is to provide high underwater glasses.

Another technical problem of the present invention is to provide practical underwater eyeglasses that have excellent wearing feeling and do not cause pain due to water pressure to the wearer's eyes even when the water pressure increases due to diving deep into the water. To provide.

Another technical object of the present invention is to provide lightweight underwater eyeglasses that are lightweight and easy to handle.

Further, other objects and technical advantages of the present invention will be clarified through the following description.

[Disclosure of the Invention]

Means taken by the inventor to solve the above technical problem include an eye patch plate having a part of a see-through window at symmetrical positions on the left and right.

The central portion of the eyepiece and the outer portions of the left and right window portions are flexibly and flexibly configured, and at least one of the two perspective windows in the eyepatch plate is used. A continuous hollow cushion tube filled with fluid is provided around the rear surface surrounding the part, and furthermore, heads are provided at the elastic left and right ends of the eye patch plate located outside the see-through window. It is to attach a tightening band.

However, if the underwater glasses are manufactured according to the present invention, the central part and the left and right outer parts of the eye patch plate constituting the front part of the underwater glasses are elastic, so that the head tightening band is pulled. To face by force The central part and the left and right outer parts are elastically deformed strictly according to the facial shape by being pulled, and the surroundings of the left and right perspective windows are surrounded by a continuous hollow cushion tube filled with fluid. Therefore, Pascal's law acts and the contact pressure of the cushion tube on the face is not evenly distributed and unevenly distributed, so that even when diving deeply, the wearer suffers from water pressure pain. In addition to making the underwater eyeglasses very comfortable to use, the design of the eye patch plate covering the front of the eye is free as long as the function of the part of the see-through window and the bent part is not hindered. Therefore, the degree of freedom in design is large, and the underwater glasses can be made of a lightweight material, so the overall weight can be reduced, and the underwater glasses can be submerged and lost by the action of a hollow cushion tube. It is the no.

[Brief description of drawings]

FIG. 1 is a front view showing an example of the shape of an eye patch plate used for the underwater glasses of the present invention, FIG. 2 is a plan view of the eye patch plate viewed from above, and FIG. FIG. 4 is a cross-sectional view taken along the line AA in FIG. 3, and FIG. 5 is a perspective view of the large underwater glasses according to the second embodiment of the present invention. .

[Best mode for carrying out the invention]

The underwater glasses shown in FIG. 3 are a first embodiment of the present invention. The underwater spectacles of the first embodiment have a perspective view in which a continuous hollow cushion tube 2 attached to the rear surface of an eyepatch plate 1 having a shape as shown in FIGS. Window 1 1 1 1 1 The front frame F includes an enclosed front frame F, and head tightening bands 3 attached to the left and right ends of the front frame F.

The eye patch plate 1 used in the first embodiment is formed of a polycarbonate resin, and is located on the right and left outer sides 12 and 12 (12 The outer portion of the perspective window (the outer portion of the window 11) and the central portion 13 to be opposed to the lower part of the eyebrows are narrow and slightly thin so that they can bend flexibly.

Further, in the present embodiment, the continuous hollow cushion tube 2 on the peripheral edge of the rear surface of the eye patch plate 1 is joined by an adhesive, but the material of the polyamide tube 6 is entirely elastic. -6 (pol yami de 6-6), which has a continuous space inside and is filled with air as shown in Fig. 4. It is substantially the same as the rubber band used, and is connected through the connecting holes 12a formed at the left and right ends of the eye patch plate 1.

Next, the underwater glasses shown in FIG. 5 are a second embodiment of the present invention. The difference between the underwater glasses of the second embodiment and the first embodiment is that the eye patch plate 1 contains a photoπ-mixed substance and changes its color when receiving ultraviolet light. The point is that a continuous hollow cushion tube 2 is provided separately for each of the left and right perspective windows 11 1 and 11 1 in the eyepatch plate 1. However, the underwater glasses of the second embodiment can withstand a higher water pressure than the underwater glasses of the first embodiment, and are suitable for scuba diving for deep diving. The embodiments specifically exemplified in the specification of the present application are substantially as described above. However, the present invention is not limited to the above-described embodiments, and may be implemented in accordance with specific needs without departing from the gist of the present invention. It can be changed as appropriate.For example, any synthetic resin material that has good translucency, high mechanical strength, and excellent impact resistance will be adopted as the synthetic resin material for molding the eye patch plate. It is also possible to add a sunglass function to the synthetic resin material by adding an ultraviolet wavelength conversion compound or a coloring pigment that converts ultraviolet light into light of a longer wavelength region and transmits the light. It should be said that it belongs to the technical scope.

[Industrial applicability]

As described above, in the underwater glasses obtained by applying the present invention, the eye patch plate that forms the shape of the front frame can be configured in a smart form close to sunglasses, so that swimming and scuba diving can be performed. It is possible for a player who enjoys (hereinafter abbreviated as “player 1”) to create a smart design that can be easily worn with the feeling of wearing sunglasses. It doesn't look strange in the sideliness, so it's undeniable that young people who value fashion will definitely help to stimulate the effective demand for underwater glasses.

In addition, in the underwater glasses of the present invention, the central part of the eye patch plate and the outer parts of the left and right rain, which are the basic elements of the front frame, are made elastic so as to be easily bent. This is determined by the tightening band. As the glasses are attracted to the face, they can bend according to the degree of curvature of the individual's face, and a continuous hollow cushion tube filled with fluid is interposed between the face and the eye patch plate. Not only does it fit straight and sharply, but also because of the equalization of the cushion tube's face contact pressure based on the skillful use of the pass force rule. Even when diving deep into the water, it does not cause pain on the face and can be worn comfortably. Therefore, due to such technical effects, the underwater spectacles of the present invention will be more popular among players and will promote an increase in effective demand.

Furthermore, since the underwater glasses of the present invention use a continuous hollow cushion tube, they do not sink and float on water, so that they can be picked up immediately even if dropped on water. As well as helping to prevent loss, it is also low in bulk and light in weight, which is convenient for carrying and handling.

As described above, according to the present invention, despite being able to overcome all of the problems that have been heretofore dissatisfied with this type of underwater glasses, it is structurally very simple and does not increase the manufacturing cost. It has many advantages in both practical and economic aspects, and its industrial utility value is extremely large.
