Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a protective lens-equipped armor that is applied to protect the face of an operator, especially the eyes, when performing spray painting or sandblasting.

(Prior Art) Conventionally, the applicant of the present invention has already reported that this type of armor is 62-109.
We are devising a protective mask described in Japanese Patent No.784.

That is, this conventional one is as shown in FIG.
The guide frame 4e is provided on the surface side of the inner lens 2e mounted on the inner lens 2e, and the transparent outer lens 7e made of a long film is attached to the inner lens 2e.
Guide frame 4e from one side to the other along the front side of 2e
It can be fed out freely by being guided by.

According to this means, the inner lens 2e, the surface of which is covered with the outer lens 7e, is not contaminated, and the contaminated outer lens 7e is successively fed in the direction of the arrow A, broken, and discarded.
The two inner and outer lenses 2e and 7e can always be kept clean.

(Problems to be Solved by the Invention) However, the above-mentioned conventional ones have the following problems when actually used by a person who performs painting work and the like.

That is, conventionally, it is necessary for an operator to grasp the dirty outer lens 7e with one hand and pull it out in the horizontal direction of the arrow A. However, when the pulling out work is urgent, the outer lens 7e can be pulled out horizontally. It is difficult, and there is a possibility that one end of the outer lens 7e may be pulled while being tilted in either the up or down direction as indicated by arrows a and b in the previous figure.

Thus, pulling the outer lens 7e in a tilted state like this,
The soft film-shaped outer lens 7e is a corner portion 23 of the guide frame 4e,
23a and the like bite into it, and not only the smooth withdrawal work cannot be performed, but also the outer lens 7e is greatly wrinkled and torn due to the bite, which hinders the original painting and other work. Was there.

Further, in the above-mentioned conventional one, since the dirty outer lens 7e is broken and discarded, there is a problem that the outer lens scatters on the work site and stains the periphery thereof, and depending on the conditions of the work site, the external lens 7e may be damaged. It may not be possible to discard the lens 7e indiscriminately. On the other hand, the outer lens 7e to which paint or the like is attached cannot be housed in a worker's pocket or the like. Therefore, conventionally, there has been a problem in terms of the handling processing of the outer lens having the stain.

Therefore, it is an object of the present invention to smoothly perform the pulling-out operation of the outer lens so as not to cause wrinkles or tears in the outer lens and to make the dirty outer lens easy to handle.

(Means for Solving the Problems) The present invention does not directly pull the dirty outer lens by hand to break and discard it as in the prior art, but does not cause the outer lens to be tilted vertically by the winding means. It is constructed so as to solve the above-mentioned conventional problems.

That is, according to the present invention, the inner lens 2 mounted on the armor body 1, the long film-shaped outer lens 7 mounted in a wound state on one side of the inner lens 2, and the outer lens 7 A guide frame 4 for guiding the outer lens 7 which is provided on the outer peripheral edge on the front surface side of the inner lens 2 so as to be able to extend to the front surface side of the lens 2.
In the armor with a protective lens, each of which is provided with a protective lens and a protective lens, the outer lens 7 being guided by the guide frame 4 and being fed out can be freely wound on the other side position of the inner lens 2. In the armor with a protective lens, the winding shaft 9 is provided along a direction substantially orthogonal to the feeding direction of the outer lens 7.

(Operation) Therefore, in the armor with the protective lens characterized by the above configuration,
When the outer lens 7 extended to the surface side of the inner lens 2 to protect the inner lens 2 becomes dirty, the winding shaft 9 provided on the other side of the inner lens 2 is rotated to move the outer lens 7 to the outer lens 7. The outer lens 7 can be fed out by winding.

Since the winding shaft 9 is substantially orthogonal to the proper feeding direction of the outer lens 7, the outer lens 7 wound around the winding shaft 9 is fed in an unjustly inclined state. Therefore, the guide frame 4 is not bitten.

Further, since the dirty outer lens 7 is sequentially wound on the winding shaft 9 and is wound and held on the winding shaft 9, the outer lens 7 is broken and discarded every time the dirty outer lens 7 is fed out. There is no need for complicated work such as performing.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

That is, the case where the present embodiment is applied as a protective mask will be described. In FIGS. 1 and 2, reference numeral 1 denotes a foamed polyester that is configured to cover the face and the like when it is worn on the head of an operator. In the body of the armor, etc., a length-adjustable wearing belt 37 and the like are appropriately provided on the rear side. Numeral 2 is a substantially rectangular inner lens made of a relatively hard transparent synthetic resin, and is provided on both sides of the window hole 3 formed at a substantially central position on the front surface of the armor body 1 so as to close the peep window hole 3. The protruding ear pieces 41, 41 are inserted through the formed insertion holes 40, 40 a and are attached to the body 1 of the protector.

Reference numeral 4 denotes a guide frame made of a relatively hard synthetic resin, the front shape of which is formed into a hollow rectangular shape. It is installed due to the reasons such as. As shown in FIG. 3, the guide frame 4 is set such that the upper edge thereof is flush with the height of the tip of the collar portion 18 of the armor body 1 or projects upward by a dimension l slightly smaller than that. A separate collar body 19 is provided so as to cover the surface of the upper edge portion. This is the guide frame 4 and the armor body 1
Paint and dust from the gap 21 between the inner lens 2 and
This is to effectively prevent the intrusion to the side.

Reference numeral 6 denotes a flat box-shaped cartridge case which is integrally or separately provided to one end of the guide frame 4 and is detachably mounted on the surface of the body 1 of the armor. 7 is a long film-shaped outer lens made of a relatively soft transparent synthetic resin.
As shown in the drawing, the cartridge case 6 is housed in a wound state and is inserted from the opening 8 of the cartridge case 6 through the guide frame 4 and the inner lens 2 to the other end of the guide frame 4. It can be drawn out to the department side one after another. Reference numeral 24 denotes a mark line attached to the outer lens 7 at appropriate intervals.

In FIG. 1 (b), reference numeral 9 is a cylindrical or cylindrical winding shaft which is mounted on the side opposite to the cartridge case 6 with the inner lens 2 interposed therebetween. As described above, the adhesive double-sided tape 25 is wound around the central portion thereof, and the collar-like body 26 and the knob 27 having the uneven surface are connected to the upper and lower sides thereof, respectively. Reference numeral 28 denotes a holder having projecting pieces 31 and 31a projecting from the upper and lower positions of the surface portion. The projecting pieces 31 and 31a have a small diameter so that the winding shaft 9 can be rotatably supported. Shaft 29,
Notch holes 30 and 30a for locking 29a are formed. In the holder 28, the projections 32, 32 on the back surface thereof and the bendable stop piece 33 are inserted into the holes 34, 34 and the slit 35 of the armor body 1, respectively, so that the projections 32, 32 are small holes of the stop piece 33. By inserting and locking 36 and 36, the take-up shaft 9
Is configured so that it can be held in a normal posture in the vertical direction.

The present embodiment has the above configuration, and a usage example thereof will be described next.

First, as shown in FIGS. 1 and 4, the outer lens 7 is attached to the guide frame 4
In a state in which the inner lens 2 is inserted between the inner lens 2 and the inner lens 2, and the inner lens 2 is covered by the outer lens 7,
One end of the outer lens 7 is adhered and fixed to the double-sided tape 25 of the winding shaft 9.

Therefore, when the outer lens 7 is soiled by performing a painting operation or the like in this state, the operator picks up the knob 27 and rotates the winding shaft 9 to extend the outer lens 7 in the direction of arrow c. The clean part of the outer lens 7 can be arranged on the surface of the inner lens 2. It should be noted that this winding dimension can be performed without waste while checking the mark 24.

At that time, since the outer lens 7 wound by the rotation of the winding shaft 9 is wound in the direction orthogonal to the winding shaft 9, the pulling direction of the outer lens 7 is the guide frame 4 and It is parallel to the inner lens 2 and there is no fear of biting into the corners of the guide frame 4, etc., and smooth feeding can be performed. In particular, since the winding shaft 9 can be rotated by operating the knob 27 projecting downward from the holder 28, an appropriate lens feeding-out replacement work can be performed even by the hand of a worker wearing gloves or the like. .

Further, since the dirty outer lens 7 is wound around the winding shaft 9, there is no need for the troublesome work of discarding the broken pieces of the dirty outer lens 7 each time the outer lens 7 is fed out. Therefore, the worker can immediately perform the original painting work or the like immediately after the feeding and replacement work of the outer lens 7.

In the above embodiment, the cylindrical or cylindrical take-up shaft 9 is supported by the holder 28 having a substantially U-shaped side surface, but the concrete shape and supporting means of the take-up shaft 9 of the present invention are It is by no means limited to the above embodiment. For example, it is also possible to provide a flexible wire-shaped member having a knob on the winding shaft 9 and rotate the winding shaft 9 while bending the wire member.

Further, in the above embodiment, the winding shaft 9 is provided so as to project to the front surface side of the armor body 1, but the present invention is not limited to this. For example, a recess may be formed on the front surface side of the armor body 1 to accommodate the winding shaft in the recess, or the winding shaft 9 may be provided on the back surface side of the armor body 1 so as to be inconspicuous on the surface. In short, the winding shaft 9 is provided at a position on the opposite side of the side where the outer lens 7 is mounted in a wound state and the inner lens 2 in a direction substantially orthogonal to the feeding direction of the outer lens 7, It suffices that it be configured to be rotatable so as to be able to wind.

Further, the present invention is not limited to the protective mask type armor that covers the upper half of the face as described above, but the protective mask type that covers the entire face, the one that is worn on a helmet to protect the face, or It can be applied to various protections such as goggles that protect only the eyes of the operator.
The present invention is not limited to any specific type of armor, and thus the specific shape of the armor body 1 is not limited.

In addition, the outer lens 7, the inner lens 2, and the guide frame 4 according to the present invention may have any specific shapes, materials, dimensions, mounting modes, etc., all of which are arbitrarily set within the scope of the present invention. Design can be changed freely. The outer lens 7 does not necessarily have to be housed in the cartridge case 6, and the inner lens 2 and the guide frame 4 may be integrated with or separate from the body 1 of the protector.

(Effects of the Invention) As described above, the present invention is dirty because the winding shaft for winding the dirty outer lens is provided along the direction substantially orthogonal to the feeding direction of the outer lens. At the time of feeding out and replacing the outer lens, unlike the conventional means for pulling the outer lens by hand, the pulling direction of the outer lens does not unnecessarily incline into the guide frame and the outer lens is wound around the winding shaft. Is smoothly fed out in an appropriate direction so that it does not bite into the guide frame or the like. As a result, according to the present invention, the outer lens feeding and exchanging work can be replaced very quickly and easily without causing the outer lens to be torn or generating a large amount of wrinkles during the feeding of the outer lens. It has come to have a special effect that it can contribute to the improvement of the work efficiency of the original work without interrupting the painting and sandblasting work for a long time.

Moreover, since the present invention allows the dirty outer lens to be wound and held on the winding shaft, it does not require the troublesome work of breaking and discarding the outer lens as in the conventional case, and the discarded outer lens can be used. Without polluting the environment around the workplace,
There is an advantage that the dirty outer lens can be conveniently handled and the armor is easy to use.
