Description

[Detailed description of the invention] This invention is an industrial mask with safety glasses, which is made by attaching safety goggles used for the purpose of dustproofing, liquid proofing, etc. to an industrial mask used for dust-proofing, gas-proofing, etc. Regarding.

(Background Art) Industrial masks used for the above purposes can be roughly divided into masks that cover not only the mouth but also the eyes and masks that cover only the mouth.

However, with the latter type of mask that covers only the mouth, the eyes are always in danger from the scattering of iron powder, dust, and liquid, such as spatter that gets into the eyes during work, for example, during welding.

However, with respect to conventional masks, apart from the former type in which the mask and glasses are integrated, there has never been one in which protective glasses that can be opened and closed are attached to the mask.

Therefore, glasses separate from the mask were used each time, but the mask was not attached to the glasses, which was extremely inconvenient, and the glasses had to be removed each time when not in use. This was a factor that worsened workability.

As a result, there was a strong demand from workers for a mask and safety glasses that were integrated into one, that could be easily attached to the eyes when in use, and that did not require the user to remove the glasses from the mask each time they were not in use. be.

(Problem to be solved/Technical objective) The object of the present invention is to solve all of the above-mentioned problems and to provide an industrial mask with safety goggles that is extremely easy to work with and has a simple structure.

(Disclosure of the present invention) In order to achieve the above-mentioned object, the present invention has a structure in which safety glasses are integrally attached to a mask so as to be rotatable. The main body 12 is rotatably mounted so as to be able to be held at a rotation stop position, and the mask main body 1 is rotatably mounted to the other end side of the support rods 9, 9' so as to be able to be held at a rotation stop position. With this structure, when in use, the eyeglass body 12 is raised up and rotated with respect to the mask body 1 around the rotation fulcrum on the other end side of both support rods 9, 9', and after the rotation, both supports are rotated. Rod 9,
By slightly rotating the eyeglass body 12 around the rotational fulcrum at one end of 9′, it is possible to make fine adjustments to ensure that the eyeglass body 12 is adapted to the eyes, so there is no risk of the eyeglass body 12 shaking during work. will never occur. On the other hand, when the glasses are not in use, the two pivot points allow the glasses body 12 to be mounted on the front surface of the mask body 1 in a compact state.

As a result, the mask can be used particularly well when glasses are used or not, and there has never been a mask with protective glasses that has such an effect.

(Effects) As described above, in this invention, the eyeglass body is integrally attached to the mask body via the two rotational fulcrums so that the eyeglass body can be rotated and held in a rotational position. You can cover your eyes by simply standing up and rotating the glasses, and you can also adapt them to your eyes by fine-tuning the glasses themselves, so you can work without any hindrance to your work due to rattling of the glasses, etc. It is extremely effective as an eye safety device, as it can reliably protect the eyes from scattering chemicals, iron powder, dust, etc. generated during work.

Furthermore, when not in use, the glasses can be mounted in a compact state on the front side of the mask body by rotating the glasses around the pivot point, so there is no need to remove them from the mask each time the glasses are not in use. It has a special effect of improving workability.
Furthermore, since the rotation stop position is maintained, there is a practical benefit of being able to set the eyeglass body at a desired position.

In this way, the present invention is extremely easy to handle, as it is only necessary to rotate the glasses body relative to the mask body when in use and when not in use, and it also protects the mouth from dust, poisonous gas, etc. when using the mask. We have developed an industrial mask with safety goggles that has two revolutionary effects: it can protect your eyes at the same time.

(Example) Hereinafter, embodiments of the present invention will be described according to an example shown in the drawings.

Reference numeral 1 denotes an industrial mask main body, in which an opening/closing lid 3 is attached to the front side of an exhaust valve body 2 so as to be openable/closable, and a filtering medium chamber is formed between the exhaust valve body 2 and the opening/closing lid 3. A sealing rubber cushion cover 5 having a chevron-shaped top 4 is fitted onto the rear of the nose to be placed on the nose.

6 is a fulcrum pin for a hinge attached to the exhaust valve body 2 so that the opening/closing lid 3 can be opened and closed; 7;
7' is a pair of connecting bodies in which both ends 6', 6'' of the fulcrum pin 6 are inserted and fixed into the seaming parts 8, 8' on one end side, respectively; 9, 9' are a pair of support rods; The inwardly bent pieces 10, 10' are rotatably inserted into the seaming portions 11, 11' on the other end side of the connecting bodies 7, 7' so as to be able to maintain the rotation stop position. 12
The main body of the protective eyeglasses is made of transparent synthetic resin, and has a substantially V-shaped notch 13 formed therein so as to be placed externally on the chevron-shaped top 4 of the cushion cover body 5.

Reference numerals 14 and 14' denote supports fixed to both sides of the notch 13 of the eyeglass body 12 with screws 15, and tightening parts 16 and 1 bent inside the supports 14 and 14'.
The outwardly bent pieces 17, 17' on the other end side of the support rods 9, 9' are rotatably inserted into the support rods 6' so as to be able to maintain the rotation stop position.

18 is the chevron-shaped top portion 4 of the cushion cover body 5;
A protrusion 19 formed by the notch 13 of the safety glasses main body 12 is provided protrudingly on the chevron-shaped top 4 in order to lock the protrusion 19 when the protrusion 19 is fitted onto the outside as shown in FIG. The locking protrusion is shown.

To explain an example of how the protective goggles are used with respect to the mask body 1 in the embodiment having the above configuration, first, when using the mask 20, the mask 20 is attached with the band 27 to cover the entire mouth including the nose as shown in FIG. do.

At this time, as shown in the figure, the safety glasses body 12 is raised and rotated about the bent pieces 10, 10' at one end of the pair of support rods 9, 9' and the fulcrum pin 6 for the hinge. Twelve projecting pieces 19 are fitted onto and placed on the chevron-shaped top portion 4 of the cushion cover body 5.

In this state, the protective glasses main body 12 almost covers the eyes, but the glasses main body 12 is attached to the bending pieces 17, 17' on the other end side of the support rods 9, 9' so that the glasses main body 12 is placed on the face. By making fine adjustments while rotating the eyeglass body 12 around the fulcrum, the eyeglass body 12 can be worn in a state that is adapted to the face as shown in FIG. In particular, in this embodiment, the connecting bodies 7, 7' are pivotally supported rotatably on the inwardly bent pieces 10, 10' of the support pin 6 and the support rods 9, 9'. 7,
The swing range of the eyeglass body 12 with respect to the fulcrum pin 6 is widened by the length l of 7', which has the effect that the fine adjustment of the eyeglass body 12 can be made freely according to the position of the operator's eyes.

When the glasses body 12 is worn in this way, with the eyeglass body 12 aligned at the desired eye position, the eyes can be protected from chemicals, iron powder, dust, gas, etc. that are scattered during work. At the same time, the use of a mask also provides dust-proofing and poison-proofing effects. In this way, by using the glasses at the same time as the mask, the worker can eliminate the dangers associated with conventional work, and the glasses main body 12 is integrally attached to the mask 20 so as to be rotatable. Therefore, the glasses can be used simply by standing up and rotating the glasses main body 12, and there is no need to prepare glasses separately, making it extremely convenient to have them permanently installed. More importantly, in the above embodiment, as shown in FIG. Therefore, even if the worker performs the work with his head down, the glasses body 12 will not inadvertently slip down or come off from the state where it is fitted onto the cushion cover body 5.

Next, after using the mask as described above, or when it becomes unnecessary to use the glasses body 12 while using the mask, move the protrusion 19 from the state shown in FIGS. 1 and 2 to the locking protrusion. While releasing the lock from the piece 18, the fulcrum pin 6 is rotated forward and downward to reach the state shown in FIG. 4A.

Next, from this state, the eyeglass body 12 is rotated upward using the outwardly facing bent pieces 17, 17' as fulcrums, and is attached to the opening/closing lid 3 side, so that the eyeglass body 12 is completely stored as shown in FIG.

Therefore, in this stored state, the eyeglass body 12
is attached to the front side of the opening/closing lid 3 in a very compact state, and at the same time, the glasses body 12 is attached to the outward bent pieces 17, 17 of the support rods 9, 9' via the supports 14, 14'. Since the eyeglass body 12 is provided so as to be able to maintain the rotation stop position at 1, the eyeglass body 12 will not inadvertently fall forward. Moreover, in this stored state, the glasses main body 12 is located at a lower position relative to the mask main body 1 by the length l of the connecting bodies 7, 7', which has the advantage of making the stored state more compact.

Next, when using the glasses 21 again from this state, as shown in FIG.
and both bent pieces 10, 10', 1 of the support rods 9, 9'
7, 17' as fulcrums and rotate it, and then press the glasses body 12 downward to release the inward bending piece 1.
0, 10' and the fulcrum pin 6, the connecting bodies 7, 7' are reversed from the state shown in the figure to the state shown in FIG.
When the outwardly bent pieces 17, 17' are turned slightly outwardly as fulcrums, the notch 13 of the eyeglass body 12 fits outwardly into the chevron-shaped top 4 of the cushion cover body 5, as shown in FIG. Glasses 2 will be placed
1 can be used.

In the above embodiment, since the lower end sides of the support rods 9, 9' and the fulcrum pin 6 are connected via the connecting bodies 7, 7', adjustment of the eyeglass body 12 when using eyeglasses is facilitated. Although there is a practical benefit in that the glasses body 12 can be stored and mounted more compactly when the glasses are not in use, the connecting bodies 7 and 7' are by no means an essential requirement for the present invention. That is, in the above embodiment, the rotation fulcrum is composed of three fulcrums: the fulcrum pin 6 and the bent pieces 10, 10', 17, and 17' at both ends of the support rods 9, 9', but it is never composed of three fulcrums. This is not a requirement, and it is sufficient if it consists of at least two fulcrums. However, if the pin for the hinge between the opening/closing lid 3 and the exhaust valve body 2 is used also as a fulcrum pin as in the above embodiment, there is an advantage that no separate fulcrum pin is required.

Therefore, the present invention is not limited to the above-mentioned embodiments, but the following embodiments can be considered.

First, FIG. 7 shows the connecting bodies 7, 7' from the above embodiment.
When the supporting rods 9, 9' are removed, the inwardly bent pieces 10, 10' of the support rods 9, 9' can be freely rotated at both ends of the fulcrum pin 6 by means of holders 22, 22' so that they can be held at rotation stop positions. This is an embodiment provided integrally.

In this embodiment, unlike the previous embodiment, there are no connecting bodies 7, 7', so the moving length of the eyeglass body 12 cannot be varied, but the support rods 9, 9'
The length of the notch 13 of the glasses body 12 when using glasses.
If it is set to a length that allows it to be placed externally on the chevron-shaped top 4 of the cushion cover body 5, it can be used in the same manner as in the previous embodiment as shown in the figure, and can be stored as shown in Figure 8 when not in use. be. Further, in each of the above embodiments, the lower rotational fulcrum is provided on the fulcrum pin 6, but as shown in FIG.
The divided lower support pieces 23, 23' are inserted into the insertion holes 24, 24' formed on both sides of the opening/closing lid 3,
The upper support pieces 25, 25' are connected to the lower support pieces 23,
23' may be connected by a pin 26 so as to be able to maintain the rotation stop position.

Therefore, the mounting position of the support rods 9, 9' is not limited to the fulcrum pin side or the opening/closing lid 3 as in the above embodiment, but may be mounted on the cushion cover body.

Furthermore, the shape of the mask is by no means limited to the embodiment, and in short, any industrial mask may be used. In addition, in this embodiment, since the rotation stop position is maintained for each fulcrum, there is a practical advantage that the positioning can be set freely. Although a locking protrusion is formed on the cushion cover body, this is not necessarily an essential requirement.
