Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to goggles that can be used for dust prevention in sports such as skiing and ski skiing, and in various production sites.

<Prior Art> In general, this type of goggles is composed of a main body that includes a lens and a frame made of synthetic resin or the like arranged around the lens, and an attachment means such as a band for attaching the main body to the human body. ing. The frame is formed into a curved shape with the center protruding from the left and right ends so as to follow the shape of the human face. That is, although the frame is molded from a relatively flexible material, it maintains its curved shape in its natural state. This frame usually has a groove formed in its inner peripheral surface, and the outer peripheral edge of the lens is inserted into this groove to attach the lens to the frame.

<Problem to be solved by the invention> However, in order to mold the frame into a curved shape with the center protruding from the left and right edges so as to follow the shape of the human face, the mold itself needs to be shaped into a three-dimensional curved shape. This makes it difficult to manufacture molds. Also, when molding the frame using this mold, a high degree of precision is required in manufacturing control, such as ensuring good resin flow. Further, frames having a three-dimensional curved shape require a large space for storage and transportation.

On the other hand, when using goggles for skiing, for example, it is necessary to put the goggles in a bag and carry them to the ski resort along with a lot of luggage such as ski wear. However, when curved goggles are placed in a protective case, they become bulky and take up a lot of space inside the bag.

<Means for Solving the Problems> Therefore, the present invention solves the above problems by providing goggles having the following configuration.

The lens in the goggles of this invention has a curved plate shape in which the left and right eye-corresponding parts are continuous at the center, and the center is located forward of the left and right ends, and also maintains its curved plate shape. It has sufficient rigidity. The frame has a shape with a smaller curvature than the curved plate shape of the lens, and also has flexibility to easily change its shape. A means for fixing the lens and the frame is provided, and the frame is deformed into a shape that conforms to the lens and is fixed to the lens. Here, the frame has a shape with a smaller curvature than the curved plate shape of the lens (hereinafter referred to as a flat shape).If the center part of the frame is located in front of the left and right ends to a smaller degree than the lens, Often, the center part does not necessarily need to be aligned with the left and right edges.

The present invention also provides the above goggles, wherein the frame has left and right eye-corresponding parts continuous at the center, and means is provided for fixing the center of the lens and the center of the frame. provide. In addition, in the present invention, "land use" excludes goggles intended for use in water, and includes goggles used for the purpose of windproofing and waveproofing even in water sports.

<Operation> In the present invention, since the frame has a shape with a smaller curvature than the curved plate shape of the lens, it can be manufactured in a planar mold compared to the lens. Therefore, it is easy to manufacture the mold, and it is also relatively easy to mold the frame using this mold. Furthermore, a frame having a planar shape does not require a large space for storage or transportation.

On the other hand, when the user carries the goggles inside the bag to a ski resort, the user can remove the lenses and frame, put only the lenses in a small protective case, and carry the goggles to a ski resort.
If the frame is flat, it won't take up much space inside the bag.

Further, by making the frame such that the left and right eye-corresponding parts are continuous at the center, and providing means for fixing the center of the lens and the center of the frame,
A flat frame with a small curvature naturally follows goggles with a large curvature. That is, the frame has a flat shape with a smaller curvature than the curved plate shape of the lens 1, and has the flexibility to easily deform the flat shape, so as shown in FIG. The central part 22 of the frame body 3 of
By fixing the center part 12 of the lens 1, the left and right eye corresponding parts 21, 21 of the frame body 3 are fixed.
is deformed to approximately the same curvature as the curved plate shape of the lens 1. Moreover, the left and right eye corresponding parts 2 of the frame body 3
Even if lenses 1 and 21 are not fixed, a force (arrow in Fig. 3) that tries to return them to their flat shape acts, and this force always presses them against the left and right eye-corresponding parts 11 and 11 of lens 1, ensuring a good fit. do.

<Example> An example of the present invention will be described below based on the drawings.

FIG. 1 is a perspective view of the goggles according to the embodiment when assembled, and the goggles include a main body including a lens 1 and a frame 2 disposed around the lens;
The main body is configured with attachment means such as a band 6 for attaching the main body to the human body.

As shown in FIG. 2, the lens 1 has a curved plate shape in which left and right eye-corresponding parts 11, 11 are continuous at a central part 12, and the central part 12 is located forward of the left and right ends. . The lens 1 is formed into a cylindrical shape using a synthetic resin such as polycarbonate having a rigidity capable of maintaining a curved plate shape, and then cut into a desired outer peripheral shape. still,
In addition to the cylindrical shape, it may have an appropriate curved shape such as a spherical shape. Further, in this embodiment, a notch 13 is formed in the upper part of the central part 12, and a nose corresponding part 14 is formed in the lower part of the central part 12. Further, through holes 15 are formed at the left and right ends.

Next, the frame 2 is composed of a frame main body 3, a central fixed body 4, and a pair of end fixed bodies 5, 5.

The frame body 3 is disposed around the inner surface of the lens 1, and is composed of left and right eye-corresponding parts 21, 21 and a central part 22 in correspondence with the lens 1. As shown in FIG. 3, this frame body 3 has a flat shape with a smaller curvature than the curved plate shape of the lens, and is made of a synthetic resin having flexibility that allows the curved plate shape to be easily deformed. has been done. In this embodiment, the center portion 22 and the left and right ends are aligned substantially in a straight line, but it is sufficient that the center portion of the frame body 3 is positioned to a smaller degree in front of the left and right ends than the lenses.

Next, the detailed shape of this frame body 3 will be explained based on FIG. 4.

First, a cushion material 23 made of foamed synthetic resin is adhered to the rear side of the frame body 3. On the other hand, on the front side of the frame body 3, there are 4
Recesses 24... are formed, and a small piece 25 of foamed synthetic resin is inserted and adhered to each recess.
This foamed synthetic resin piece 25 closes the small space formed between the recess 25 and the lens 1 when the lens 1 is attached, while allowing air to flow therethrough, and prevents snow and dust from entering. It is. Frame body 3
A small hole 26 is formed in the upper center of the front side. Moreover, three small holes 27 are formed in the center of the lower part. There are many grooves 28 on both sides of the lower part.
. . . are formed, and these grooves 28 . . . form a large number of small spaces for air conduction between the lens 1 and the lens 1 when the lens 1 is attached. A projecting portion 29 is formed on both sides of the front side of the frame body 3, and a through hole 30 is formed in the projecting portion 29. Further, as shown in FIG. 5, cushion materials 23 are provided on both left and right sides of the frame body 3.
An insertion space 31 for inserting a band attachment device, which will be described later, is formed between the two.

Next, the central portion fixing body 4 will be explained based on FIGS. 6 and 7. The central fixing member 4 is for removably fixing the lens 1 to the frame body 3, and the back surfaces of the upper fixing member 41, which is rectangular in front view, and the lower fixing member 42, which is inverted U-shaped, are connected to the connecting member. 43. Each of the upper fixing member 41 and the lower fixing member 42 is formed with pressing pieces 44 and 45 extending toward the front surface. As a result, grooves for inserting the lens 1 are formed, and in each groove,
The lens 1 can be fixed by inserting the cut portion 13 and the nose corresponding portion 14 of the lens 1, respectively. Furthermore, fixing protrusions 46, 47, . . . are formed on the back sides of the upper fixing member 41 and the lower fixing member 42, respectively. These fixing protrusions 46, 47...
They are forcibly fitted into the small holes 26, 27, . . . of the frame body 3, respectively, and are fixed to the frame body 3. In order to ensure the fitting by these fixing protrusions 46, 47..., it is also preferable to provide a bulge at the tips of the protrusions.

In addition to the above embodiment, the connection by the connecting member 43 may be performed between the surfaces of the upper fixing member 41 and the lower fixing member 42, or it is not necessary to connect them. Furthermore, the central fixing body 4 is not a separate body,
It may also be formed integrally with the frame body 3.
Moreover, a fixing protrusion similar to the above may be formed on the inside of the lens 1 by integral molding or by adhesion.

Next, the end fixing body 5 will be explained based on FIG. 8. This end fixing body 5 consists of a plate-shaped part 51 and a columnar part 52 protruding from the plate-shaped part, and a constricted part 53 is formed in the vicinity of the tip of the columnar part.

Finally, the band 6 can be the same as the conventional one. In this embodiment, a device having attachments 41 for attaching to the frame body 3 at both ends is used, so that the band 6 can be attached to and detached from the frame body 3. As shown in FIG.
is formed. The distal end side of the elongated hole 63 is a small hole portion 64 with a slightly smaller diameter.

The goggles of this embodiment are constructed from the above-mentioned members, and the assembled state of the goggles will now be described.

First, the central fixing body 4 is attached to the lens 1. As described above, this installation involves inserting the notch 13 and the nose corresponding part 14 of the lens 1 into the grooves for inserting the lens 1 formed in the upper fixing member 41 and lower fixing member 42 of the central fixing body 4, respectively. The process is completed by inserting the respective lenses and fixing them to the lens 1.

Next, the center portion 21 of the flat frame 2 and the center portion 11 of the lens 1 are fixed. This fixation is
This is done by forcibly fitting the fixing protrusions 46, 47... of the central fixing body 4 into the small holes 26, 27... of the frame body 3, respectively. Here, frame 4
has a flat shape with a smaller curvature than the curved plate shape of the lens 1, and has the flexibility to easily deform the flat shape. By fixing the central part 22 of the shaped frame body 3 and the central part 12 of the lens 1, the left and right eye corresponding parts 21 of the frame body 3,
21 is deformed to approximately the same curvature as the curved plate shape of the lens 1. Moreover, the left and right eye-corresponding parts 21, 21 of the frame body 3 are subjected to a force (arrow in FIG. 3) that tends to return to a flat shape even if they are not fixed, and this force always acts on the left and right eye-corresponding parts of the lens 1. Corresponding part 11,1
1 and fits well.

Next, insert the insertion piece 62 of the band 6 into the insertion space 31 of the frame, and insert it into the through hole 15 of the lens 1.
Insert the cylindrical part 52 of the end fixing body 5. As a result, the cylindrical part 52 penetrates the through hole 30 of the frame,
The constricted portion 53 at the tip of the cylindrical portion is the insertion piece 6 of the band 6.
2 into the elongated hole 63. From this state, by further pulling the insertion piece 62 in the proximal direction, the constricted part 53 at the tip of the columnar part is moved into the small hole part 64 of the elongated hole 63.
The fixation is completed.

As described above, the lens 1 and the frame 2 are fixed at the center and at both left and right ends. In this way, the left and right eye-corresponding parts 21, 21 of the frame 2 do not need to be fixed. However, as long as it is not fixed, lens 1
Although there remains a possibility that a slight gap may exist between the head and the frame 2, when the band 6 is attached to the head, this gap disappears. Further, even if a gap remains, the minute gap acts as an air passage hole, so even if it may be advantageous to the use of the goggles, it will not be disadvantageous. Of course, lens 1
and frame 2 may be fixed over their entire circumference.

In addition to the above embodiments, the present invention can be implemented with various modifications, and the upper fixing member 41 and the lower fixing member 4
2 may be extended in the lateral direction to increase the number of fixing locations using fixing protrusions, or the number of fixing locations may be increased using a structure similar to that of the end fixing body 5. In addition, the end fixing body 5
The fixation is limited to fixing the lens 1 and the frame 2, and the frame 2 and the band 6 may be fixed by other fixing means. Further, although a single lens 1 is used, a double lens may be used.

<Effects of the Invention> In the present invention, since the frame has a flat shape with a smaller curvature than the curved plate shape of the lens, it can be manufactured in a relatively flat mold. Therefore, it is easy to manufacture the mold, and it is also relatively easy to mold the frame using this mold. In addition, for frames with a flat shape, during inventory and transportation,
Doesn't require large space.

On the other hand, when the user carries the goggles inside the bag to a ski resort, the user can remove the lenses and frame, put only the lenses in a small protective case, and carry the goggles to a ski resort.
If the frame is flat, it won't take up much space inside the bag.

Further, the frame is such that the left and right eye-corresponding parts are continuous at the center, and a means for fixing the center part of the lens and the center part of the frame is provided on at least one of the lens and the frame. A flat frame with a small curvature naturally follows the goggles with a large curvature, and the lens and frame fit well without having to fix the frame and lens around the entire circumference. As a result, even if a simple means for fixing the lens and frame is used, the integrity of the lens and frame is good. Therefore, it is extremely advantageous for goggles with interchangeable lenses.
