[0008]
DETAILED DESCRIPTION OF THE INVENTION
An eyeglass according to an embodiment of the present invention, particularly sunglasses will be described with reference to the drawings.
Embodiment 1
FIG. 1 is a front view of sunglasses according to Embodiment 1 of the present invention, FIG. 2 is a side view of the sunglasses with a single lens removed, and FIG. 3 is a plan view of the sunglasses.
(About the configuration of this sunglasses)
As shown in FIGS. 1 to 3, this sunglasses includes a brace bar 1 and a nose pad portion 2, and has temples 3 and 3 foldably attached to both ends of the brace bar 1. The single lens 4 is held by the central portion 1 and the nose pad portion 2. In the sunglasses of this embodiment, the brace bar 1 and the nose pad portion 2 are integrally formed of a synthetic resin, and the single lens 4 can be replaced without a tool depending on the purpose.
[0009]
The brace bar 1 is set to a length that substantially matches the width of the single lens 4 as shown in FIGS. 1 and 3, and is formed in a substantially arc shape in plan view so as to substantially follow the shape of the lower part of the person's forehead. It is. Here, in the vicinity of both ends of the brace bar 1, as shown in FIGS. 1, 3, and 4, recesses 10a and 10b are formed on the front and rear surfaces, and the center of the recess 10a on the front surface is substantially omitted. An oval air inflow / outlet hole 10 is formed. Further, as shown in FIG. 2, a groove 11 into which the central portion of the upper edge of the single lens 4 is fitted is formed on the lower surface of the central portion of the brace bar 1.
[0010]
As shown in FIGS. 1 to 3, the nose pad portion 2 is formed in a substantially inverted V shape, and a rubber pad 20 is pasted on the surface facing the face so as to softly contact the nose. . Further, as shown in FIG. 2, the nose pad portion 2 is formed with a groove 21 extending in a substantially inverted V shape into which the central portion of the lower edge of the single lens 4 is fitted.
[0011]
The temples 3 and 3 are made of the same synthetic resin as the brace bar 1 and are attached to the brace bar 1 via hinges 5 as shown in FIGS. The hanging part 6 is fitted.
[0012]
The single lens 4 is a spherical lens, and is attached in such a manner that the center portion of the upper edge is fitted into the groove 11 and the center portion of the lower edge is fitted into the groove 21. In addition, as a replaceable lens, a transparent lens, a lens that cuts light of a specific wavelength, a polarizing lens, a mirror lens, and the like can be prepared.
[0013]
In this sunglasses, as shown in FIG. 3, the left and right upper edge portions of the single-lens lens 4 are arranged in front of the brace bar 1 with a gap g, and the single-lens lens 4 is pushed forward from the front ( When the wind pressure mainly from the front during speed sports is applied, the left and right upper edge portions of the single lens 4 are brought into contact with the brace bar 1 with a predetermined pushing amount.
(About the advantages of this sunglasses)
(1). Depending on the size of the face width, the vines 3 and 3 are spread out and the brace bar 1 is deformed. In this sunglasses, only the central part of the single lens 4 is held by the central part of the brace bar 1 and the nose pad part 2. Therefore, only the portion that does not affect the field of view is deformed, so that the image seen through the single lens 4 is hardly distorted.
(2). Even if a large pushing force acts on the single lens due to wind pressure or the like from the front during speed sports, the left and right upper edge portions of the single lens 4 come into contact with the brace bar 1 with a predetermined pushing amount. The single lens 4 is not excessively deformed.
(About replacing the single-lens lens 4 with these sunglasses)
(1). For example, the lower edge of the left lens portion of the single-lens lens 4 near the nose pad portion 2 (the portion indicated by symbol A in FIG. 4) is picked with a finger and pulled out toward the front, and the lens portion is generally extracted from the groove 21.
(2). While maintaining the above state, the lower edge in the vicinity of the nose pad portion 2 in the right lens portion of the single-lens lens 4 is picked up with a finger and deformed and pulled out toward the front. Then, the center of the lower edge of the single lens 4 is completely removed from the groove 21, and the single lens 4 can be removed by pulling out the single lens 4 to the front as it is.
(3). When attaching the single lens 4, for example, the center of the upper edge of the single lens 4 is fitted in the groove 11, and the lower edge of the right lens part of the single lens 4 near the nose pad 2 is generally fitted in the groove 21. If the lower edge in the vicinity of the nose pad portion 2 in the left lens portion of the single lens 4 is deformed and pushed in while maintaining, the mounting of the single lens 4 is completed.
(4). As described above, in the sunglasses, the single lens 4 can be exchanged according to the purpose by the operations (1) to (3).
[Other Embodiments]
In the sunglasses of the above-described embodiment, the single lens 4 can be exchanged according to the purpose. However, the single lens 4 can be exchanged without being limited thereto. Even in this case, there is an effect that the image seen through the single lens 4 is not easily affected by the size of the face width.
[0014]
【The invention's effect】
Since the present invention is configured as described above, it has the following effects.
