Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to sports goggles having a shock absorbing function.

(Prior Art) Conventionally, there are the following types of sports goggles of this type.

No. 61-203726 (FIG. 4) A frame 101 holding a lens 100, and a thin plate pad 102 having substantially the same shape and size as the frame 101 and having elasticity are provided. Then, a spacer 103 having elasticity was inserted between the frame 101 and the pad 102 at a predetermined interval to form a gap L between the frame 101 and the pad 102.

When the ski goggles 104 are worn, the pad 102 contacts the face. And shock to the frame 101,
That is, when an external force is applied, the spacer 103 and the pad 102 are elastically deformed and absorbed.

Actual Kaihei No. 1-84620 (Fig. 5) In this ski goggle 200, a shock absorbing member 203 is provided inside a frame 202 holding a lens 201.

The shock applied to the frame 202 is the shock absorbing member 203.
Absorbed by.

(Problems to be solved by the invention) However, the above-described conventional example has the following problems.

(A) Since the frames 102, 202 are ready-made shapes, it is not possible to fit them according to the facial shape of each user,
It is easy to shift the position.

(B) The spacer 103 and the pad 102 are not elastically deformed, and the impact absorbing member 203 does not sufficiently absorb the external force, and the impact may be transmitted to the face.

(C) Frame 101, pad 10 when strong impact is applied
2 and the frame 103 are plastically deformed and cannot be worn.

(D) Frame 101, pad 10 to prevent (c) above
2, and it is also possible to set the frame 103 to be thick to increase the rigidity, but it is not practical because not only the user is easily tired because the overall weight increases but also the field of view becomes narrow.

The present invention is intended to solve the above problems, and an object thereof is to provide sports goggles having a good fitting feeling and a sufficient shock absorbing function. Another purpose is to provide sports goggles that are lightweight, compact, and resistant to impact.

(Means for Solving the Problem) In order to achieve the above object, the present invention relates to a sports goggle having a frame holding a lens, wherein the frame is made of a super elastic member having shape memory performance according to a facial shape. And a flexible shock absorbing member that covers the periphery of the core material.

Further, the shock absorbing member is preferably made of elastomer or soft synthetic resin.

Further, the soft synthetic resin may be a shape memory resin having a predetermined shape memory property.

Furthermore, the core material of the frame may be extended to the temple side and embedded.

(Operation) The present invention based on the above-mentioned structure is such that the flexibility of the shock absorbing member and the shape memory performance of the core material are surely brought into close contact with the face, and the external force applied to the frame is the shock absorbing member and the core material. Absorbed by both.

Further, the core material has a sufficient external force absorption function due to the superelastic effect, can withstand a strong impact, and even if it is deformed, it can be restored to its original shape by the shape memory performance.

Further, if the shock absorbing member is an elastomer or a soft synthetic resin, it feels good on the skin and a better fitting feeling can be obtained.

Furthermore, if the core material is also embedded on the temple side,
Since the external force applied to the frame can be dispersed and absorbed not only in the frame but also in the frame and the temple, the external force absorbing function is further improved. In addition, the fitting feeling of the temple itself is improved, and deformation due to external force is less likely to occur.

(Example) Next, this invention is demonstrated based on FIGS. 1-3.

FIG. 2 is a perspective view of ski goggles 1 as an example of sports goggles. The frame 3 holding the left and right lenses 2 is configured by integrally forming a main body portion 4, a support portion 5, and a pad 6. FIG. 1 is a sectional view taken along the line AA of FIG. That is, the frame 3 is composed of a core material 7 made of an elastic member having a shape memory performance according to the facial shape of the user, and a flexible shock absorbing member 8 covering the periphery of the core material 7. There is. As the core material 7
Various alloys such as Ni-Ti alloys and copper alloys, or shape memory polymer materials can be used, and the shock absorbing member 8
For this, a soft synthetic resin or an elastomer may be used.

In addition, temples 9 are attached to both ends of the frame 3 through hinges 9.
10 are connected in series so that they can be opened and closed.

 Next, the operation of the above embodiment will be described.

When the user wears the ski goggles 1 on the face, the inner surface 3a of the frame 3 contacts the face (forehead). here,
Since the shape memory performance previously given to the core material 7 and the flexibility of the shock absorbing member 3 are combined, a good fitting feeling can be obtained along the shape of the face, so that a defect such as a positional deviation does not occur. If an impact absorbing member 8 is made of an elastomer or a soft synthetic resin, it feels good on the skin and gives a better fitting feeling. Further, the impact applied to the frame 3, that is, the external force, is absorbed by both the impact absorbing member 8 and the core 7. Particularly, since the core material 7 has a sufficient external force absorbing function due to the superelastic effect, the frame 3 is not easily deformed even when a strong impact is applied. Therefore, it is lightweight and compact, does not cause fatigue even if the user wears it for a long time, and can secure a sufficient visual field. Further, even if the frame 3 is plastically deformed by an extremely strong impact, it can be restored to the original shape by the shape memory performance of the core material 7, and can be continuously worn.

Further, if the shock absorbing member 8 is also made of a shape memory resin (norbornene resin or the like) having a predetermined shape memory performance, the external force absorbing function and the shape restoring effect are further improved in cooperation with the core material 7. .

In addition, in the above-mentioned embodiment, although the core material 7 is embedded only in the frame 3, the temple 3 is used.
A core material made of a super elastic member having shape memory performance may be embedded in the 10 side as well (not shown). With this configuration, both the frame 3 and the temple 10
Not only the feeling of fitting the ski goggles 1 to the face is further improved, but also the applied shock is applied to the frame 3
Since it can be dispersed and absorbed on the side temple 10 side, the external force absorbing function is further enhanced, and the temple 10 itself is less likely to be deformed. In this case, it is needless to say that the temple may be integrally formed with the frame instead of being connected via the hinge as shown.

Although the ski goggles have been described as an example in this embodiment, the ski goggles are not limited thereto and can be widely used as goggles for various sports such as bicycles.

(Effect of the Invention) Since the present invention is configured as described above, a good fitting feeling along the shape of the face can be obtained, and no displacement occurs. Further, the frame is not easily deformed even when a strong impact is applied, and it is lightweight and compact so that the user is less tired and a sufficient visual field can be secured. Further, even if the frame is deformed due to an extremely strong impact, the frame can be restored to the original shape and the wearing can be continued.

In addition, if an elastomer or a soft synthetic resin is used as the shock absorbing member, the skin feels good and a better fitting feeling can be obtained.

Moreover, if a shape memory resin is used as the soft synthetic resin,
The external force absorption effect and shape restoration effect are further improved.

Furthermore, both the frame and the temple not only improve the feeling of fitting the face of the sports goggles, but also absorb the applied impact by distributing it to the frame side temple side, which further enhances the external force absorption effect. However, it has various excellent effects that the temple itself is not easily deformed.
