Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to goggles mainly applied to welding, sandblasting, and various other operations.

(Prior Art) As is well known, goggles used for dustproofing and other work purposes are designed to minimize the gap formed between the goggle body and the face to prevent harmful dust from entering the goggles. It is necessary to prevent this.

Therefore, conventionally, as shown in FIG. 4, the planar shape of the rear side of the goggle body 1e with the eyepiece 3 on the front side is formed into a curved shape (arrow R) that roughly follows the curved state of the face. Therefore, many methods are employed, such as attaching a soft elastic member 20 such as urethane foam to the curved portion.

(Problem to be Solved by the Invention) However, in the conventional means, in order to bring the rear side of the goggle body 1e into appropriate contact with the user's curved face, the curve depth L of the rear side of the goggle body 1e is insufficient. It is necessary to make it quite large. Therefore, in the past, in order to ensure the bending depth L, the front-to-back width La of the entire goggle body also increased, resulting in an increase in the size of the goggle body 1e. As a result, the goggles are inconvenient to handle, and especially during use, the goggle body 1e protrudes significantly in front of the user's face, making it difficult to wear and use the goggles comfortably.

In addition, as a measure to solve the above-mentioned difficulty, it is possible to increase the thickness of the elastic member 20 and reduce the curvature depth L. However, the elastic member 20
If the goggle body 1e is made thick, the wearing state of the goggle body 1e becomes unstable, and in practice, there is a certain limit to reducing the bending depth L of the rear surface portion of the goggle body 1e. Therefore, the reality is that simply increasing the thickness of the elastic member 20 does not adequately solve the above-mentioned problems.

Furthermore, an important problem is that although there are considerable individual differences in the shape and dimensions of the user's face, the curved shape of the rear side of the conventional goggle body is uniformly formed. It is not possible to change the shape of the face in response to the shape of the face. Therefore, in the past, although the gap between the goggles and the face is eliminated to some extent by the presence of the elastic member 20, it is still not possible to completely eliminate the gap by itself, and there is a possibility that dust may unduly infiltrate into the goggles. There was still a risk.

Therefore, the present invention aims to appropriately prevent harmful dust and the like from entering the goggles, regardless of the shape of the user's face, etc., while minimizing the size of the goggles. That purpose.

(Means for solving the problem) The present invention does not greatly curve the back surface of the goggle body itself as in the past, but instead creates a member separate from the goggle body to cover the gap between the goggle body and the face. By providing a movable type, the above-mentioned conventional problems are attempted to be solved.

That is, the present invention provides a goggle in which: 1 a pair of left and right strings 2 are attached to a goggle body 1;
Cover pieces 5, 5 having upper and lower pieces 7, 7a and side pieces 8 are attached to the side walls 1a, 1a of the goggle body 1, and the covers 5, 5 extend toward the rear side of the goggle body 1. It is provided so as to be able to move forward and backward so that the protrusion dimension M can be increased or decreased, and between the cover pieces 5, 5 and the goggle body 1, the cover pieces 5, 5 are positioned and fixed at a predetermined position. A fixing means is provided.

(Function) In the above configuration, by moving the cover pieces 5, 5 in and out of the goggle body 1, the rearward protrusion dimension of the goggle body 1 can be changed in accordance with the shape of the user's face, etc. Since the cover pieces 5, 5 can be moved freely, the cover pieces 5, 5 can be brought into close contact with the user's face regardless of the shape of the user's face.
5 and the face can be eliminated.

Moreover, by positioning and fixing the cover pieces 5, 5 by the fixing means, it is possible to maintain a proper close contact between the cover pieces 5, 5 and the face, so that the cover pieces 5, 5 are not unduly displaced during work. There is no need to create a gap between the goggles and the face.

(Example) Examples of the present invention will be described below.

In FIG. 1, reference numeral 1 denotes a goggle body formed in the shape of a hollow frame made of metal or hard synthetic resin, and its longitudinal width S is formed to be approximately uniform at each location.

Reference numerals 2 and 2 indicate a pair of left and right strings for attaching the goggle body 1 to the face, and 3 indicates a transparent or translucent eyepiece attached to close the position of the opening 4 on the front surface of the goggle body 1. .

Reference numerals 5 and 5 are cover pieces made of flexible synthetic resin attached to the peripheral wall of the goggle body 1, and the cover piece 5 is attached to the side wall 1 of the goggle body 1.
a, 1a is provided, and the upper and lower ends of the side piece 8 are integrally formed with an upper piece 7 and a lower piece 7a that are generally fan-shaped in plan and have arcuate end surfaces 6, 6a. are connected in series.

9, 9 are respective upper and lower pieces 7 of the cover pieces 5, 5;
These pins are rotatably attached with one end side of 7a adjacent to the top wall 10 and bottom wall 11 of the goggle body 1, respectively, so that the cover pieces 5, 5
is rotatable in the direction of arrow A about the pin 9 as a fulcrum so that it can move in and out of the goggle body 1.

Reference numeral 12 designates a plurality of locking holes drilled in the side pieces 8 of the cover pieces 5, 5 along the front-rear direction. 13
are locking protrusions that are bent and protrude inward from both side walls 1a, 1a of the goggle body 1, and are inserted into the locking holes 12 to position the cover piece 5, as shown in FIG. This is for fixation. still,
These locking holes 12 and locking protrusions 13 constitute a fixing means.

The present embodiment has the above configuration, and next, an example of its use and operation will be explained.

First, each cover piece 5, 5 can be rotated about the pin 9 as a fulcrum to make it protrude toward the rear side of the goggle body 1.
It can be freely increased or decreased by adjusting the rotation angle. Therefore, the user only has to set the protrusion amount M to a state convenient for him and wear the goggle body 1 on his face.

As a result, both end surfaces of the goggle body 1 and the face position, as well as the upper and lower parts of the goggle body position and the face position are all covered by the cover pieces 5, 5.

If a gap occurs between the cover pieces 5, 5 and the face in this state, by rotating and adjusting the cover pieces 5, 5 again, the face and the cover piece 5,
5 can be almost completely eliminated. After that, the locking protrusions 13 may be inserted and locked into appropriate positions of the locking holes 12 of the cover pieces 5, 5. With this, the cover pieces 5, 5
This prevents the wearer from rotating, thereby eliminating the possibility of creating an unreasonable gap between the cover pieces 5, 5 and the face during work using the goggles. Therefore, it is possible to reliably maintain the close contact between the cover pieces 5, 5 and the face.

Further, the locking protrusion 13 for the locking hole 12
Since the fitting/locking is removable, the positioning of the cover pieces 5, 5 can be repeated. Therefore, other workers with different facial shapes can easily use the same goggles.

Furthermore, when the goggles are not in use, the cover pieces 5, 5
What is necessary is to push it into the goggle body 1 to make it compact. If the width of the cover pieces 5 is so large that the entire width cannot be accommodated in the goggle body 1, the flexible cover pieces 5, 5 may be bent inward from appropriate positions as shown in FIG. This allows the strings 2, 2 to be folded inward, making it convenient for carrying.

Incidentally, in the above embodiment, the cover pieces 5, 5 are fixed with pins and provided rotatably relative to the goggle body 1, but the present invention is by no means limited to this. For example, as shown in FIG. 3, the cover pieces 5, 5 may be provided so as to be slidable toward the rear side of the goggle body 1.
Even in such a case, the purpose of the present invention can be achieved.

Further, in the above embodiment, the locking protrusions 13 are fitted and locked into the locking holes 12 formed in the cover piece 5, so that the means for positioning and fixing the cover piece 5 is made very easy. However, it is not necessarily necessary to employ such means in the present invention. Various other positioning and fixing means can be used. In the case of FIG. 3, for example, the elongated hole 2 bored in the cover piece 5
It is also possible to adopt means such as inserting the bolt nut 22 through the bolt 1.

Further, the specific shape, size, material, etc. of the cover pieces 5, 5 can be freely changed in design depending on the shape of the rear side of the goggle body 1, etc., and are by no means specified as in the above embodiment. do not have.

Further, the present invention is not limited to the specific configuration of the goggle body as in the above embodiments, and its application is not limited to those for various types of work. Of course, it can also be applied to sports such as skiing and motorcycles.

In addition, the design of the present invention can be freely changed in the specific configuration of each part within the scope of the present invention.

(Effects of the invention) As mentioned above, the present invention provides a cover piece on the goggle body to cover the gap that occurs between the goggle body and the face, so it can be placed on the rear side of the goggle body as in the conventional case. Since there is no need to form a deep curved portion, the goggle body can be made more compact than the conventional goggle body. Therefore, when the goggles are in use, the goggle body does not protrude more than necessary to the front of the face, and when the goggles are not in use, the size of the cover piece protruding from the goggle body is reduced, making it convenient for carrying. Improves ease of handling.

Moreover, in the present invention, the protruding dimension of the cover piece toward the rear of the goggle body can be changed and its position can be fixed, so that the shape of the conventional goggle body is uniform and fixed. Therefore, there is no risk of creating a large gap between the goggles and the face due to differences in the shape of the user's face, and any user can adjust the cover piece to fit the cover piece to the face. There is also an excellent effect that the goggles can be accurately brought into close contact with the person and the close state can be maintained, and one goggle can be used appropriately by multiple people.

In addition, since the cover piece has upper and lower pieces and side pieces, the side pieces of the cover piece cover the gap between the face and the end of the goggle body, and the upper and lower pieces cover the gap between the face and the upper and lower walls of the goggle body. can cover the gap between
It is possible to cover almost the entire circumference of the goggle body, which has the practical benefit of further improving its dust-proofing effect.

Moreover, since the goggles of the present invention have a string-equipped cover piece that can be adjusted, any user can adjust the cover piece and bring the cover piece in close contact with the face as described above. The advantage is that it can be worn comfortably without giving the user a feeling of pressure, even though it can cover almost the entire circumference of the goggle body, further improving its dust-proofing effect, etc. There is.
