Description

[Technical field]

[0001] This invention relates to goggles with a face shield that are worn to protect the face from flying chemicals when handling chemicals, and to a face shield that can be attached to the goggles. [Background technology]

[0002] Dust is generated when cutting, grinding, mowing, or using a chainsaw. In order to prevent the dust from getting into your eyes, workers usually wear goggles. However, while goggles can prevent dust from entering the eyes, they cannot prevent it from being inhaled. For this reason, a filter suitable for the work purpose is provided to prevent inhalation of dust particles and harmful gases, and exhalation is made through the filter when breathing. In other words, a face mask that combines a goggle section and a mask section is used.

[0003] On the other hand, in addition to work that generates dust and harmful gases, there is also work that involves handling chemicals, and care must be taken to prevent the chemicals being scattered and hitting one's face while working. Conventional face masks that combine goggles and a mask do not cover the entire face and cannot protect against chemical substances that may splash around during work. Dust and toxic gases float in the air and are not harmful if they come into contact with the face unless inhaled. However, wearing a mask makes it difficult to breathe and makes it difficult to work.

[0004] Helmets with face shields attached to the front have been commercially available, and can protect the face and head from flying objects, powder splashes, and splashes of chemicals and solvents. However, the face shield is fixed to the helmet by screws or the like, and it is not easy to remove and replace the face shield when it becomes dirty. Also, it is not possible to adjust the inclination of the face shield.

[0005] The "dustproof goggles" pertaining to Utility Model Registration No. 3237610 are dustproof goggles to be worn when dust is generated, and are dustproof goggles that can prevent the intrusion of dust, small pieces of grass, etc. from the outside and efficiently prevent fogging of the lenses that occurs when the goggles are worn. These dustproof goggles are composed of a lens portion placed on the front, a frame portion attached around the lens portion, and a dustproof portion which is attached around the rear of the frame portion and has a top, both sides and a bottom. Openings are drilled in the top, both sides and bottom of the dustproof portion, and a mesh body is attached to the openings to prevent dust from entering.

[0006] The "goggles" disclosed in JP 2003-169821 A can prevent splashes and water droplets from entering while ensuring breathability. The goggles are comprised of an eyeglass section made of transparent synthetic resin that is positioned in front of the wearer's eyes, a dustproof section made of flexible synthetic resin to protect the eyes from dust, splashes, water droplets, etc., and a rubber band for fixing the goggles to the head. The upper and lower parts of the dustproof section are formed with ventilation holes consisting of numerous small holes that allow air to pass through, and these ventilation holes are covered in isolation by a mesh sheet that is water-repellent and breathable.

[0007] In this way, wearing goggles can protect the eyes from accidents that occur during work, but even if you wear goggles, when working with chemicals, it cannot prevent chemicals from splashing around and hitting your face. [Patent Document 1] "Dust-proof goggles" related to Utility Model Registration No. 3237610 [Patent Document 2] "Goggles" according to JP 2003-169821 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0008] As described above, goggles with various functions have been known for some time. However, the purpose of the present invention is to protect the face from chemical substances such as medicines that may splash around, and conventional goggles cannot achieve this purpose. The problem that the present invention aims to solve is this problem, and it provides goggles with a face shield that can protect not only the eyes but also the entire face. [Means for solving the problem]

[0009] The goggles with face shield of the present invention are constructed by attaching a face shield made of a transparent thin plastic plate to the front of the goggles. The face shield has a removable mounting structure so that it can be removed when it becomes dirty, and holes are provided at both side ends of the face shield and protrusions are provided on both sides of the goggles. The face shield is attached to the goggles by fitting the holes into the projections, so that it covers not only the face but also the front portion of the goggles. The outer diameter of the tip of the projection is made slightly larger, and is sized so that the hole engaged with the projection can be locked so as not to easily come off.

[0010] Here, the face shield is a transparent, thin plastic plate, and the shape thereof may be flat or may be a smoothly curved plastic plate with an appropriate curvature. The goggles integrated with the face shield can be put on and removed from the head in this state. The face shield, which is attached by engaging the hole with the convex portion, can swing up and down around the convex portion, so that the inclination of the face shield can be adjusted and it can be lifted upward when not needed. Effect of the Invention

[0011] Goggles with a face shield can protect not only the eyes but also the face if worn on the head. In other words, the eyes are protected by the goggles and the face by the face shield, so even if chemicals such as acetone splash around during work, they will not hit the eyes or face. The face shield prevents flying chemicals from hitting the face, but because it is attached to the goggles and covers the front, flying chemicals will not hit the front of the goggles.

[0012] Therefore, if the face shield becomes soiled by splashed chemicals, it can be replaced with a new one by simply inserting the hole at the side edge of the face shield into the protruding part of the goggles. Face shields protect not only the face but also the goggles from flying chemicals, allowing expensive goggles to be used for a long period of time. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] 1(a), (b), and (c) are concrete examples showing typical goggles 1, where (a) is a plan view, (b) is a front view, and (c) is a side view. A stretchable band 3 is attached to the front part 2 so that the goggles can be worn by wrapping them around the head. The inner surface 4 of the front portion 2 is soft and smoothly curved so that it can fit closely to the face without any gaps, and a smoothly curved lens 5 is fitted to the front. Here, the present invention does not limit the specific structure or shape of the goggles 1, and the goggles 1 may have a ventilation function to prevent the lenses 5 from fogging up.

[0015] FIG. 2(a) is an external view of goggles 1, and FIG. 2(b) shows the goggles 1 with a face shield 6 attached. The face shield 6 is attached so as to cover the front of the front part 2 of the goggles 1 and so as to protect the entire face when worn.

[0016] FIG. 2(c) is an embodiment showing the face shield 6 alone. The face shield 6 is a transparent, thin plastic plate, and the front surface 7 is smoothly curved. Small holes 8, 8 are provided through both side ends, and the holes 8, 8 engage with protrusions 9, 9 protruding from the sides of the goggles 1, thereby allowing the face shield 6 to be attached. The face shield 6 is smoothly curved when attached to the goggles 1, but may be a flat plastic plate before attachment.

[0017] FIG. 3(a) is a side view of the goggles 1, and a band 3 that wraps around the head is attached to a front portion 2 of the goggles 1. The band 3 is connected to a connector 10 attached to the protrusion 9, so that the front part 2 can be adjusted to change its direction by swinging with the protrusion 9 as an axis relative to the band 3 wrapped around the head. FIG. 3(a) shows the state in which the front portion 2 faces slightly diagonally downward.

[0018] 3(b) is a side view of the goggles 1 with the face shield 6 attached, and the face shield 6 is attached by engaging holes 8, 8 with protrusions 9, 9 provided on both sides of the front part 2. Therefore, the direction (tilt) of the face shield 6 can be changed around the protrusions 9, 9 as an axis. That is, when the front part 2 is inclined slightly downward with respect to the band 3 wrapped around the head so as to fit closely to the face, the face shield 6 swings about the protruding part 9 as an axis, and the orientation can be changed to make work easier. Figure 3(b) is a side view showing this state. FIG. 3( c ) shows a side view of the face shield 6 .

[0019] FIG. 4(a) shows an enlarged view of the connection portion when the face shield 6 is attached to the front part 2 of the goggles 1. The connector 10 and the face shield 6 are attached via a protrusion 9 provided on the front portion 2, so that the connector 10 and the face shield 6 can each change their orientation independently with the protrusion 9 as an axis. FIG. 4(b) is an enlarged view showing the connection state between the front portion 2 and the connector 10 when the face shield 6 is not attached.

[0020] A small circular hole 8 is provided at the side end of the face shield 6, and the face shield 6 is attached by engaging the hole 8 with a protrusion 9. Here, the size of the hole 8 is such that it will not easily come off the protrusion 9, and the tip of the protrusion 9 has a larger outer diameter so that it can engage with the hole 8 and prevent it from coming off. The protrusion 9 shown in FIGS. 1(a) and 1(b) is a stepped protrusion whose tip outer diameter is made larger so that the hole 8 does not come off. [Explanation of symbols]
