Description

[Detailed description of the invention] (Field of industrial application) This invention can be used to suitably accommodate protective lenses and filters such as protective masks used when performing painting, sandblasting, etc. Regarding cartridges.

(Prior art) Conventionally, this kind of protective mask has been used, for example, No. 10.
As shown in the figure, in order to prevent dirt on the inner lens 30 that covers the cutout window 12 formed in the mask body 11, a soft outer lens 31 of a fixed size is replaced as appropriate on the surface side of the inner lens 30. There is a device that allows the outer lens 31 to be attached and detached, but with this method, it is troublesome to insert and detach the outer lens 31 into a small gap 33 of the frame 32, etc. 31 had the disadvantage that wrinkles appeared and visibility became poor.

Therefore, in an attempt to solve the above-mentioned difficulties, the applicant of the present invention has developed the system disclosed in, for example, Japanese Utility Model Application No. 60-203218. That is, as shown in FIG. 11, this protective mask has a soft and elongated outer lens 4 and a bottomed body for housing the outer lens 4 in a perfectly circularly wound body. A substantially cylindrical cartridge 34 is separately provided. Therefore, according to this means, when the outer lens 4 becomes dirty, the outer lens 4 can be sequentially drawn out to the surface side of the inner lens 13 and cleaned by simply pulling the outer lens 4. Moreover, it is now possible to suitably prevent the formation of undue wrinkles on the outer lens 4 due to the tension.

(Problem to be solved by the invention) However, in the conventional method, when the entire length of the outer lens 4 is extended, the cartridge 3 naturally
Since the lens 4 itself must be reset, the total length of the outer lens 4 must be increased in order to improve its usability.

However, since the conventional cartridge 34 is formed into a substantially cylindrical shape and accommodates the outer lens 4 wound in a perfect circle, the long outer lens 4 is When wound in a circular shape, the winding diameter becomes large, and the cartridge 34 that accommodates it also becomes large, resulting in a problem that its thickness and outer diameter become large.
As a result, for example, as shown in the same figure, the cartridge 34
When the cartridge 34 is attached to the back side of the mask body 11 to prevent the cartridge 34 from getting dirty with paint etc., the large diameter cartridge 34 is placed between the worker's face and the mask body 11. In addition to causing the problem of putting pressure on the worker's face and causing discomfort, the larger the cartridge 34 becomes, the more difficult it becomes to attach it to the mask body, etc., making it difficult to handle. Moreover, the manner in which the cartridge 34 is mounted is also very unsightly.

The present invention has been devised in consideration of the above-mentioned problems of the conventional art, and its purpose is not limited to cartridges for storing outer lenses as protective lenses, but also to cartridges for storing various long protective members used in this type of protective mask, so that even when the length of the long protective member is increased, the cartridge can be properly stored and used without significantly increasing its thickness, thereby improving the ease of use of the cartridge and its appearance when in use.

(Means for Solving the Problems) The present invention does not store a long protective member in a perfect circular shape as in the past, but by winding it in a flat shape to reduce its thickness. This structure is designed to solve the above-mentioned conventional problems by reducing the size of the protective member and also by making the unwinding operation more suitable when the elongated protective member is wound into a flat shape.

That is, the gist of the configuration of the present invention is that the cartridge case 1 is configured to be flat so that the elongated protective member 4 can be accommodated in a flatly wound state, and that the inside of the cartridge case 1 is flat. When the elongated protective member 4 is fed out, the elongated protective member 4
The guide shaft 6 for preventing the portion on the side opposite to the feeding side from moving toward the feeding side can be positioned at the inner end of the elongated protective member 4 on the side opposite to the feeding side. It is provided separately within Case 1.

(Function) Therefore, in the cartridge for storing an elongated protective member characterized by the above structure, the elongated protective member 4 can be stored in the cartridge case 1 in a flatly wound state. Therefore, even if the elongated protective member 4 has a long overall length, the thickness dimension when the elongated protective member 4 is accommodated can be made small, and the cartridge case 1 itself for accommodating the elongated protective member 4 can also be made very compact. The cartridge case 1 can be made thin and compact, and the length of the elongated protective member 4 accommodated therein is not limited to a short size due to the thinness of the cartridge case 1.

In addition, when the elongated protective member 4 housed in the cartridge case 1 in a flat wound state is fed out to the outside of the case 1, normally the elongated protective member 4 on the inside of the case 1 is When the entire protective member 4 moves toward the unwinding side under tension, its proper winding state is disrupted, making it difficult to pull and unwind. Since the portion of the elongated protective member 4 on the opposite side from the feeding side is prevented from moving toward the feeding side by the guide shaft 6, this makes it difficult to feed out the elongated protective member 4. This problem is eliminated, and smooth workability for feeding out the elongated protective member 4 can be ensured.

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

In FIG. 1, reference numeral 1 denotes the cartridge main body 1a having the above-mentioned open and flat box-like shape, and the main body 1.
This shows a synthetic resin cartridge case consisting of a flat lid 1b that can be fitted onto the upper surface of the main body 1a, and the lid 1b can be rotated by using a stopper 2 or the like at one end of the main body 1a. It is pivoted freely. Reference numeral 3 indicates a notch provided on the upper surface of the tip end of the main body 1a of the cartridge case 1, and the notch 3 is provided when the cartridge case 1 is closed, as shown in FIG. 2A. It functions as a feeding port 3 for feeding out the outer lens 4 housed in the lens 1 to the outside. As shown in FIG. A mark 47 for confirming the position is displayed. Reference numeral 5 indicates a mounting piece provided on the lower surface of the tip of the cartridge body 1a, and the mounting piece 5 serves as a means for attaching the cartridge case 1 to a protective mask body, etc. .

Reference numeral 6 indicates a guide shaft, which has a small diameter extending across the width direction of the case 1 at one end (inner part) side of the main body 1a of the cartridge case 1, and both ends of the guide shaft 3 are connected to both side walls of the main body 1a. They are removably fitted and locked into cut-outs 8, 8a of a predetermined shape cut into the upper surfaces of the members 7, 7a.

Therefore, the cartridge with the above configuration is
As shown in FIG. 2A, a long film-shaped outer lens 4 serving as a protective member is housed in the cartridge case 1 in a state in which it is wound repeatedly in a flat shape around the guide shaft 6, and one end thereof It is used by attaching the outer lens 4 to a predetermined position on a protective mask with the lens exposed from the outlet 3, but the work of winding the outer lens 4 around the guide shaft 6 requires This can be easily done by removing it from the cartridge case 1. Furthermore, since the elongated outer lens 4 is wound into a flat shape, its thickness L can be made very small even when its total length is long, and the elongated outer lens 4 can be wound into a flat shape. It can be suitably accommodated in the cartridge case 1.

Next, the cartridge is attached to the protective mask body 11 at the bottom of the helmet 10, for example, as shown in FIG.
It can be suitably used as a cartridge for feeding out the outer lens 4 for a protective mask in which the viewing cutout window 12 of the protective mask body 11 is covered with a relatively hard inner lens 13. It is.

That is, as shown in FIG.
After the outer lens 4 is fixedly attached to the back side of the cartridge case 1, the outer lens 4 is drawn out from inside the cartridge case 1.
of the mask body 11 through an opening 15 provided between the back side of the mask body 11 and the inner frame 14 and an opening 17 provided between the front side of the mask body 11 and the outer frame 16. By exposing the surface side, the surface of the inner lens 13 is covered with the outer lens 4, and the worker wears a protective mask and uses it in this state.

However, when wearing the protective mask,
Since the cartridge case 1 located on the back side of the mask body 11 is very thin, the cartridge case 1 does not press against the worker's face and give an unpleasant feeling of pressure, making the worker comfortable. You will be able to perform various tasks.

Also, during the painting process, if the outer lens 4 becomes dirty, one end 18 of the outer lens 4 that is exposed on the surface side of the mask body 1 can be pulled to gradually clean the outer lens. 4 can be fed out from inside the cartridge case 1 to keep the surface side of the inner lens 13 in a good visibility condition at all times. However, as shown in FIG. One end 1 of the inner peripheral part of the outer lens 4
9, the guide shaft 6 is inserted through it, so when one end 18 of the outer lens 4 is pulled, the entire wound outer lens 4 is pulled toward the tip of the cartridge case 1 as shown in FIG. Therefore, the outer lens 4 will not be in a tight state within the case 1, and the outer lens 4, which is subjected to tension, will be smoothly drawn out to the outside along the guide shaft 6.

Furthermore, if the outer lens 4 is extended, the dirty part of the outer lens 4 will hang down to the front side of the protective mask body 11, but in this case, the mark 47
After confirming that the notch 46 is located near the frame 16 by looking at the position of the notch 46, the outer lens 4 can be easily broken and removed at the notch 46 position.

Incidentally, in the above embodiment, the elongated protective member 4
Although the explanation is given using an outer lens as a specific example, the specific type of the elongated protective member 4 according to the present invention is by no means limited to this, and other elongated protective members 4, for example, may be used. It may also be configured as a gas mask filter to prevent inhalation of unclean air during painting work or the like. Further, as a matter of course, the notches 46 and the like for breaking the elongated protective member 4 are not a requirement.

Therefore, the present invention is not limited to the specific configuration of the protective mask to which the cartridge is attached as described above; for example, as shown in FIG. The mask body 11 is rotatably provided with respect to the helmet 10 made of Main body 1
The thin cartridge 1 can be suitably positioned in a small gap between the back surface of the mask and the surface of the lower mask body 42. In this case, if a notch 43 for attaching and detaching the cartridge 1 is provided on the side of the mask body 1, there is an advantage that the attaching and detaching operation can be performed from the outside of the mask.

As described above, the protective masks to which the cartridge according to the present invention can be used come in a variety of configurations and types, and the present invention can also be suitably used for other protective goggles used in painting work, etc. It is.

Furthermore, in the present invention, the position where the cartridge is attached is not limited to the back side of the mask body as in the above embodiment, but may be provided on the front side of the mask body, or a protrusion 44 may be provided at a predetermined position of the cartridge 1 as shown in FIG. A small hole 4 protrudingly formed in the inner lens 13
It may be integrally provided at the end of the inner lens 13 by means such as press-fitting into the inner lens 5 .

Furthermore, in the above embodiment, the cartridge case 1 is constructed of both the case body 1a and the lid body 1b, so that the elongated protective member 4 can be accommodated in a substantially completely sealed state. The present invention is by no means limited to this, but in order to reduce the thickness of the cartridge case 1 even slightly and to simplify its structure, for example, the lid body 1b is removed from the cartridge case shown in FIG. As shown in FIG. 4, a shaft-shaped restraining member 21 is appropriately provided in place of the lid 1b at the top opening of the case body 1a, and due to the presence of the restraining member 21, the elongated protective member 4 is attached to the case body. There is no problem even if it is made so that it does not jump out from 1a. In this case, the upper opening of the case body 1a may be closed with a mask body, etc., and the elongated protective member 4 can be extended by using a mask provided at the tip of the case body 1a as described above. A cutout or the like may be used as the outlet 3.

Furthermore, the cartridge case 1 according to the present invention has the following features:
For example, the overall external shape may be formed into a curved shape as shown in FIG. It has the advantage of being easy to use.

As described above, the specific configuration of the cartridge case 1 according to the present invention can be freely changed in design,
In short, it is configured in a flat shape that can accommodate the elongated protective member 4 in a flat wound state and has an outlet 3 for sequentially feeding out the accommodated elongated protective member 4 to the outside. Just knock it down. Needless to say, the specific shape and position of the outlet 3 are not limited to those in the above embodiments.

Furthermore, in the above embodiment, the guide shaft 6 is fitted and locked into the notches 8, 8a provided in the side wall of the cartridge case 1, so that the guide shaft 6 can be freely attached to and removed from the cartridge case 1. In order to establish
Although it has the advantage that the work of positioning the guide shaft 6 inside the long protection member 4 wound in a flat shape is very easy, the specific means for attaching the guide shaft 6 according to the present invention is also difficult. The present invention is not limited to this, and it may be provided in a fixed state with respect to the cartridge case 1.

6, the present invention can be applied to a shaft 21 for supporting the inner end of the long protective member 4 on the payout side, separate from the guide shaft 6, and in this case, when winding the long protective member 4 in a flat shape, the long protective member 4 can be wound around the guide shaft 6 and the shaft 21, improving workability. Furthermore, in the same figure, a pipe-shaped member 22 is fitted onto the guide shaft 6, and the pipe-shaped member 22 is rotated when the long protective member 4 is paid out, making the payout operation of the long protective member 4 even smoother.
In the present invention, such a means is not essential and may be provided optionally.

As described above, the specific structure of the guide shaft 6 according to the present invention can be freely changed in design, and the point is that the elongated protective member 4 accommodated in the cartridge case 1
When one end of the elongated protection member 4 is fed out to the outside, the portion of the elongated protection member 4 opposite to the feedout side is located at the inner end opposite to the feedout side. It is only necessary that the cartridge be provided within the cartridge case 1 to prevent the cartridge from moving.

In addition, this invention has specific shapes and materials of each part,
The size, mounting structure, etc. can all be changed within the scope of the present invention.

(Effects of the invention) As described above, the present invention is superior to the conventional method because the cartridge is formed into a flat shape and the elongated protective member can be stored inside the cartridge in a flat state. Unlike a cylindrical cartridge in which a long protective member is housed inside with the long protective member wound in a perfect circle, the winding dimension when storing the long protective member does not become large, and the thickness of the long protective member is reduced. By reducing the dimensions, the thickness of the cartridge can also be made very small, and as a result, when the cartridge is attached to a protective mask, etc., the cartridge becomes a nuisance for the worker and becomes a hindrance to the work. In addition to the fact that it can be easily attached to a protective mask, it is easy to handle and can be used in a suitable manner, which is a particularly remarkable effect.

Moreover, the present invention prevents the portion of the elongated protective member on the opposite side from the dispensing side from moving toward the dispensing side when the elongated protective member housed in the cartridge case is dispensed to the outside. Since a guide shaft is separately provided inside the cartridge for this purpose, when this kind of long protective member is wound into a flat shape, the entire long protective member is pulled toward the cartridge outlet side when it is fed out. This will allow us to properly resolve the problems that make it difficult to feed out the work.
An excellent effect has been achieved in that the elongated protective member can be smoothly fed out and its practicality can be ensured.

As described above, the present invention makes the cartridge itself compact by winding the elongated protective member into a flat shape and reducing its thickness, and also by winding the elongated protective member into a flat shape. By separately providing a means to remove the harmful effects of unwinding when wound into a shape, we have been able to provide an extremely practical cartridge.It also has the advantage of being simple in structure and easy to manufacture, making it easy to put into practical use. The value is enormous.
