Description

  The present invention relates to goggles, and more particularly to goggles used for sports.

  Examples of goggles used for sports include those used for swimming.

  11 and 12 are bottom views showing examples of conventional swimming goggles, respectively. 11 and 12, only the left and right sides of the goggles are shown.

  11 and 12, the swimming goggle 30 includes a pair of left and right eye cups 9 having the lens portion 1, a mounting belt 4, and a belt attachment portion 3 that receives the belt 4. A nose belt (not shown) for connecting the left and right eye cups 9 is attached to the nose belt attaching portion 8A. Here, in the goggles shown in FIG. 11, the belt attaching portion 3 is provided at the outer end portion 9 </ b> A of the eyecup, and the cushion portion 2 is provided on the face-facing side of the eyecup 9. In FIG. 12, the belt attaching portion 3 is provided outside the eye cup 9 (on the opposite side of the human head) so that the belt 4 does not press the human head.

  By the way, Japanese Patent Application Laid-Open No. 11-33139 (conventional document 1) discloses an example of a swimming goggles having the cushion portion as described above.

In the swimming goggles of Conventional Document 1, a front peripheral wall portion and a side portion made of a hard transparent material are provided within a certain range of the lens peripheral wall portion, and a rear peripheral wall portion and a cushion portion are connected to the rear of these, and The inclination angle of the outer surface of the lens peripheral wall portion with respect to the lens surface is made smaller than 65 °. With this configuration, it is possible to ensure a wide field of view of the wearer.
Japanese Patent Laid-Open No. 11-33139

  However, the above goggles have the following problems.

  When the goggles are attached to the person's head, the folded belts and the belt and the person's head are not completely in close contact with each other, and a slight gap is formed. When the wearer of the goggles moves in the fluid (for example, underwater), the fluid flows into these gaps, causing the belt to flutter, causing the fluid resistance of the goggles to increase. This increase in resistance becomes more prominent as the gap is larger.

  For example, in FIG. 11, in order to ensure the strength of the belt attachment portion 3, the attachment portion has a certain thickness (L in FIG. 11). Therefore, a gap 5 (first gap) is formed between the belts near the turn due to the rigidity of the belt. Note that the gap between the belts is formed in the same manner, for example, in the goggles shown in FIG. 11 and 12, a gap 6 (second gap) is formed between the human head (one-dot chain line in FIGS. 11 and 12), the belt 4, and the eye cup 9.

  On the other hand, Conventional Document 1 does not disclose the idea of suppressing the fluid resistance by minimizing the gap.

  From a viewpoint different from the above, for example, in the goggles (swimming goggles) shown in FIG. 12, there is a problem that the fluid directly hits the belt at the belt mounting portion and causes an increase in fluid resistance.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide goggles with low fluid resistance.

In one aspect, the goggles according to the present invention include a pair of eyecups having a lens portion and a portion extending obliquely rearward from the end portion of the lens portion along the head of the wearer, and a pair of eyecups.

It is located on the opposite side of the wearer's head and is formed so that the face-facing surface of the cowl portion follows the belt when worn.

  This makes it difficult for the fluid to flow into the gap formed between the belts of the folded portion and the gap between the human head, the belt, and the eye cup, thereby suppressing the belt flapping in the fluid. A goggle with low fluid resistance can be provided.

  According to the present invention, the gap in the vicinity of the belt formed at the time of wearing can be minimized and the fluid resistance of goggles can be suppressed.

  In the following, embodiments of goggles according to the present invention will be described.

  First, “goggles” in this specification means goggles used for various sports such as skiing and cycling. In this embodiment, swimming goggles for swimming will be described as an example.

The swimming goggles according to the present embodiment include a pair of left and right eye cups having a lens portion, a nose belt that connects the left and right eye cups, a belt that fixes the eye cup and the nose belt to the wearer, and a contact between the eye cups. And a belt attaching portion that rises toward the face side and receives the belt.

  In the conventional swimming goggles, in order to ensure the strength of the belt mounting portion, the member has a certain thickness, and as a result, there is a gap (first gap) between the folded belts due to the thickness and the rigidity of the belt. There is a problem that the belt is fluttered by the fluid flowing into the gap and the resistance is increased.

  On the other hand, in the swimming goggles according to the present embodiment, the strength of the belt mounting portion can be ensured by the width of the rising portion, and the portion sandwiched by the folded belt can be formed thin. Therefore, the first gap can be minimized, and the flapping of the belt in the fluid can be suppressed.

  The goggles further include a cushion portion provided on the face-facing side of the eye cup on the outer peripheral portion of the lens portion. Here, the thickness in the rising direction of the belt mounting portion at the end of the cushion portion on the belt mounting portion side (the distance from the face-facing surface of the eye cup to the face-facing surface of the cushion portion) is the rise of the belt mounting portion. The sum of the height and the thickness of the belt is substantially equal, or the thickness of the cushion portion is larger than the sum of the height of the belt attaching portion and the thickness of the belt.

  Here, when the thickness of the belt mounting portion of the cushion portion in the rising direction is larger than the sum of the height of the belt mounting portion and the belt thickness, the cushion portion is pressed and thinned when the goggles are attached. Thus, the thicknesses of both are made substantially equal.

  The cushion portion may be provided inside the outer shape of the eyecup, or may be provided according to the outer shape of the eyecup.

  In the vicinity of the outer end of the eyecup, a step is created between the face-facing side of the eyecup (cushion if a cushion is provided) and the belt surface in the vicinity of the eyecup. A space (second space) is formed between the eye cup and the eye cup.

  On the other hand, in the swimming goggles according to the present embodiment, the line connecting the face-facing side surface at the end of the cushion portion and the belt surface of the folded portion located in the vicinity of the cushion portion is a human head line. Almost matches. Therefore, the above-described step is small, and the belt and the human head can be brought into close contact from a position close to the belt mounting portion. As a result, the second gap can be minimized, and the fluid resistance of goggles can be further suppressed.

  In addition, even when the thickness of the cushion portion described above and the sum of the height of the belt mounting portion and the thickness of the belt are slightly different, if the same effect as described above is obtained by being substantially equal, They should be understood as equal.

  In other words, the configuration of the above swimming goggles is as follows. That is, the swimming goggles according to the present embodiment include a pair of eyecups having a lens portion and a cowl portion extending obliquely rearward from the end portion of the lens portion along the head of the wearer, and a pair of eyecups. , A belt for fixing the eye cup and the nose belt to the wearer, and a belt attaching portion provided inside the cowl portion for receiving the belt.

  Here, the belt attaching portion may be provided so as to stand up from the cowl portion of the eye cup, or may be provided so as to stand up from the end portion of the eye cup where the cushion portion is provided. Further, the eye cup may be provided with a protruding portion along the face of the wearer so as to form a concave portion between the cowl portion and the protruding portion, and a belt attaching portion may be provided so as to rise from the concave portion. .

  The lens portion and the cowl portion are typically formed integrally, but the eye cup may be configured by combining the lens portion and the cowl portion formed as separate members.

  As described above, since the cowl portion is provided outside the belt attachment portion, the turbulent fluid is less likely to flow into the first and second gaps described above. As a result, the flapping of the belt in running water can be suppressed, and the fluid resistance of the swimming goggles can be reduced. In addition, the effect of preventing the shift of goggles in running water can be expected.

  Hereinafter, embodiments of goggles according to the present invention will be described with reference to FIGS.

  1A and 1B are diagrams illustrating a swimming goggle according to a first embodiment, where FIG. 1A is a front view and FIG. 1B is a bottom view. 2 is a perspective view of the goggles, and FIG. 3 is a cross-sectional view taken along the line III-III in FIG. In FIG. 1 to FIG. 3, illustration of a belt for mounting is omitted.

  As shown in FIGS. 1 to 3, the swimming goggles 30 according to this embodiment include a pair of left and right eye cups 9 having a lens portion 1, a nose belt 8 that connects the left and right eye cups 9, and an eye cup 9. And a belt mounting portion 3 that rises substantially vertically toward the face-facing side and receives a belt for wearing. Here, the eye cup 9 has a cowl portion 7 extending obliquely rearward from the end portion of the lens portion 1 along the head of the wearer, and the belt attaching portion 3 is provided inside the cowl portion 7. It has been. A cushion part 2 is provided on the face-facing side of the eye cup 9 in order to improve fit.

  Here, the lens part 1, the belt attaching part 3, and the cowl part 7 are made of polycarbonate, and the cushion part 2 and the belt are made of a soft material such as rubber, elastomer, or silicon.

  In this embodiment, the nasal belt 8 is directly connected to the eye cup 9, but a nasal belt mounting portion may be provided on the eye cup and the nasal belt may be attached to the mounting portion.

  FIG. 4 is a view showing a state where the swimming goggles 30 are attached to the wearer. In FIG. 4, only the left and right sides of the goggles are illustrated, and the alternate long and short dash line in FIG. 4 indicates the human head line.

  Referring to FIG. 4, the strength of belt attaching portion 3 is ensured by increasing the width of the rising portion (L1 in FIG. 4) to some extent (about 2.5 mm in this embodiment). Therefore, the portion of the member 3 sandwiched between the belts 4 can be formed thin (about 1.5 mm in this embodiment). As a result, the gap 5 (first gap) formed between the folded belts 4 can be minimized.

  Similarly, in FIG. 4, the sum (H1) of the rising height of the belt mounting portion 3 and the thickness of the belt 4 is the rising direction of the belt mounting portion 3 of the cushion portion 2 at the end on the belt mounting portion 3 side. Is substantially equal to the thickness (H2).

  As a result, the face-facing side surface at the end of the cushion portion 2 and the surface of the belt 4 on the belt mounting portion 3 are connected at the shortest distance when worn, so that it is formed between the human head, the belt 4 and the eye cup 9. The gap 6 (second gap) to be made can be minimized.

  In consideration of the fact that the pressed cushion portion 2 becomes thinner when the goggle is mounted, the thickness (H2) of the cushion portion 2 is made larger than the total height (H1) of the belt mounting portion height and the belt thickness. May be.

As described above, by minimizing the first and second gaps, flapping of the belt 4 due to water flowing into the gaps can be suppressed in running water. Moreover, by providing the cowl portion 7, it is possible to prevent flowing water from flowing into the gap in a turbulent state. As described above, the resistance of the swimming goggles 30 in running water can be suppressed. Further, it is possible to prevent the goggles from shifting in running water.

  FIG. 5 is a diagram showing data comparing resistances that the swim goggles according to the present embodiment and the conventional swim goggles receive in running water.

  The data shown in FIG. 5 is obtained by a resistance test using a human head model. The resistance test will be described below.

In FIG. 6, the circulating water tank 22 is filled with water, and the water is circulated in the direction of the arrow in FIG. 6 by the internal propeller 11 connected to the motor 10. And in the measurement part 12, the human head model which fitted swimming goggles is settled from the upper part of this water tank, and the resistance which this human head model receives is measured. A surface acceleration device 13 is installed on the downstream side of the measurement unit 12.

  FIG. 7 is a diagram showing a state in which a resistance test using a human head model is actually performed. As shown in FIG. 7, the human head model 14 is attached to a rectifier body 15, and the rectifier cylinder 15 is connected to a strain gauge 18 via a column 16 and a connecting rod 17. As a result, the resistance that the human head model 14 receives from the water flow is measured by the measuring device 19 (dynamic strain meter) as an electrical signal from the strain gauge 18 and displayed and recorded on the computer 21 via the A / D converter 20. The In addition, the speed of the water flow in this measurement was 1.4 m / s, 1.6 m / s, and 1.8 m / s. In addition, the resistance value of each swimming goggles alone is obtained by subtracting the resistance value of the human head model measured without wearing goggles from the resistance value of the human head model measured with each goggles wearing. ing.

  In addition, as the swimming goggles of Conventional Example 1 and Conventional Example 2, swimming goggles having structures shown in FIGS. 11 and 12 were used. In these swimming goggles, as shown in FIGS. 11 and 12, the gaps 5 and 6 are formed larger than the swimming goggles according to the present embodiment.
