Description

The present invention relates to a sliding face shield.

In recent years, when treating infectious disease patients, doctors and medical professionals wear face shields as a measure to prevent infectious diseases and to prevent splashes of viruses and bacteria.

A device that rotates with respect to the head gear is known for the conventional vertical operation of the face shield between a position covering the face and eyes and a position away from the face. The structure of the upper and lower jigs is complicated, and it is inconvenient because it protrudes in front of the face.

The sliding plastic cover sheet plate is known as a sun visor for cars, but the sliding plastic cover sheet plate has a function of being stored in the sun visor opaque body or the ceiling of the vehicle body, which is different from the fully transparent face shield.

Recently, it has been used by the general public as a preventive measure against new coronavirus and influenza. Adults, school children, and childcare children of the general public must consider the difference in head and face size and behavior when using the face shield.

When eating and drinking in nursing homes, schools and restaurants, the face shield must be uncovered. If the transparent plastic sheet plate rises above the nasal cavity, it will be easier to eat. However, the existing face shield will come off. In addition, the flip-up type has a defect that the face part opens wide and the prevention of splashing is weakened.

In the present invention, the sliding transparent plastic cover sheet plate moves up and down to shorten the height in the vertical direction by about half, so that food and drink can be eaten without removing the cover of the face shield.

The size of a general face shield is about 0.2 to 0.3 mm x 33 cm x 22 cm in thickness x width x height, it is a little large to carry, and it is difficult to store it in a bag or school bag.

Mouth shields made of transparent plastic covers can now be seen in the hospitality industry such as restaurants and shops. The transparent mouth shield, which covers only the mouth and has an open top, is intended to prevent hospitality workers from ejecting their own droplets.

The transparent mouth shield prevents splashes from the mouth to some extent, but it is not effective on the effective area wall of the mouth. In addition, the transparent mouse shield is fixed to the ear hook type, and it is somewhat difficult to wear an ear hook type non-woven fabric mask together.

It is a sliding face shield, and the face shield plate has a function that a fixed transparent plastic cover sheet plate and a transparent plastic cover sheet plate that slides on the inner surface thereof slide in the vertical direction.

The fixed transparent plastic cover sheet plate may be placed in front of the user's eyes. Between the lower position where the movable transparent plastic cover sheet plate covers the user's mouth and the upper position above the lower position and overlapping the fixed transparent plastic cover sheet plate back and forth. You may slide it. In order to contact the inner surface of the fixed transparent plastic cover sheet plate and slide it accurately, sliding rail file clip tubes are provided on both sides of the face shield in the vertical direction. Sliding rail file clip A transparent plastic cover sheet that slides with the scissors of the cylinder is held up, down, left and right. The pair of left and right sliding rail file clip cylinders support both sides of the fixed transparent plastic cover sheet plate and the sliding movable transparent plastic cover sheet plate so as to be slidable in the vertical direction. The sliding rail file clip cylinder utilizes the scissors force to hold both sides of the fixed transparent plastic cover sheet plate and the movable transparent plastic cover sheet plate in the front-rear direction. The sliding rail file clip tube is provided over the entire vertical direction of the side portion of the fixed transparent plastic cover sheet.

A stopper is provided so that the sliding movable transparent plastic cover sheet plate does not come off from the fixed fixed transparent plastic cover sheet plate.

The sliding rail file clip tube must be firmly fixed for the sliding movable transparent plastic cover sheet plate to move smoothly.
As for the fixing method with the face shield, the surface side of the seat plate and the slide type rail file clip cylinder are joined.

The sliding movable transparent plastic cover sheet is cut open with a slight curve in the center of the lower part, so that the upper part of the lips does not hit the end of the face shield when eating or drinking.

The opening at the top of the fixed transparent plastic cover sheet plate is devised so that the sliding face shield can be used as a transparent mouth shield.

Cooks and salespeople generate sighs and spit from their mouths when talking in customer service. The transparent mouse shield is not enough to prevent splashes. However, when wearing a non-woven mask, the expression is invisible because the mouth is hidden. In addition, it is important for cooks and sales staff to determine the quality of food and products.

The upper opening of the fixed transparent plastic cover sheet plate of the sliding face shield improves visibility and improves the ventilation inside the face shield so that the facial expression can be clearly seen.

The sliding face shield can prevent splashes by 180 degrees at the mouth, and when used in combination with a non-woven mask, it has a further splash prevention effect.

The sliding face shield of the present invention can be adjusted to a size suitable for the user's own physique. Adults and children, men and women have different head sizes and face sizes. For example, children have small heads and faces, and standard-sized face shields are too large to fit. Since the sliding face shield can be adjusted in the height direction, the height can be adjusted to suit the face. The width does not become smaller, but it can be adjusted to the size of the head by using the function that can adjust the length of the elastic rubber band.
That is, the sliding face shield of the present invention can be used by everyone.

It is difficult to eat and drink with the existing face shield attached, but the height of the sliding face shield can be adjusted, so you can raise it to the top of your own nasal cavity and there is a notch along the lips, so the face shield is covered. Easy to eat and drink without taking.

Since the size is variable, by shortening the height direction, it is easy to put it in a bag, school bag, medical bag and it is convenient to carry.

For example, if you bring it with you on an overseas trip and use it in a place where the infection environment condition is unknown, it will prevent splashes to some extent.
It also prevents sighs from splashing during cheering battles when watching sports.

If you make the sliding face shield of the present invention using the recently developed transparent plastic cover sheet board material that blocks 99% UV rays, for example, it will be a face sun visor that can be adjusted in size at the beach, and the face. Can prevent sunburn.

Industrial face shields are well known, but they are sturdy and heavy, and the product of the present invention is lightweight and inexpensive, making it a suitable tool for users. To protect.

The sliding face shield can prevent splashes more than the mouse shield of the customer service worker, and the opening opened to improve the visibility does not cause diffuse reflection or cloudiness of the plastic cover, so high quality customer service can be performed.

Next, a mode for carrying out the invention will be described.

As shown in FIGS. 1 to 10, the sliding face shield of this embodiment is a face shield that can be used by doctors, medical professionals, and the general public.

FIG. 1 A state in which a sliding transparent plastic cover sheet plate is lowered under the chin with the sliding face shield of the present invention. FIG. 2 is a perspective view showing the seat plate 3 raised above the nasal cavity. When eating and drinking, the seat plate 3 does not block the mouth, so you can eat and drink without removing the face shield.

FIG. 3 has a configuration that does not cover the sliding face shield, and the sheet plate 3 slides up and down in the vertical direction on the inner surface of the transparent plastic cover sheet plate 2 fixed in the file clip cylinder 1. It is fixed to the head and forehead with a tooth profile sponge 4 having ventilation holes and an elastic rubber band 5. The elastic rubber band stopper length of the elastic rubber band 5 can be adjusted so that it can be used by women and children with small faces. The elastic rubber band stopper 7 can be used to adjust the elastic rubber band stopper length.

A person who uses the sliding face shield of the present invention first feeds the sheet plate 3 up inside the face shield, and if he / she wants to make it smaller, he / she uses the human body left finger 8 and the human body right finger 9. It is firmly fixed by the scissors force of the file clip cylinder 1.

If you want to make it larger, slide it with the movements of both fingers 8 and 9 as shown in FIG. 4-Send the sheet plate 3 downward. It is devised so that the seat plate 3 does not accidentally fall off when it is fed downward.

In the image diagram of FIG. 5, an opening 10 is provided in the middle of the file clip cylinder 1. The state in which the seat plate 3 is inserted from below is shown. Further, an R-shaped notch 15 is provided in the center of the lower end portion of the sliding transparent plastic cover sheet plate.

FIG. 6 is an enlarged view of a portion surrounded by a circle in FIG. The reason why the seat plate 3 does not fall out downward is that wedge-shaped stoppers 12 are attached to both sides on the seat plate 3. The wedge-shaped stopper 12 is cut out from the sheet plate 3 and bent at 90 degrees, indicating that the wedge-shaped stopper 12 hits the lower end portion 13 of the opening 10 of the file clip cylinder and cannot move downward. The shaded portion A indicates the range where the sheet plate 2 and the sheet plate 3 overlap and are joined when the sliding transparent plastic cover sheet plate 3 is lowered to the place where the sheet plate 3 cannot slide.

FIG. 7 shows a state in which the sliding transparent plastic cover sheet plate 3 is inserted from below the sliding rail file clip cylinder 1.

FIG. 8 shows, as another embodiment 1, even if the wedge-shaped stopper 12 is cut out from the sheet plate 3 and the resin wedge-shaped stopper 14 manufactured in a separate frame is attached on the sheet plate 3 with an adhesive without bending. good.

Next, a method of using the sliding face shield according to the embodiment of the present invention will be described. In FIG. 1, if the sliding face shield is to be enlarged, the sliding transparent plastic cover sheet plate 3 can be lowered to the portion 13 where it cannot slide downward to reach the full cover size before being covered. If you want to make it smaller, slide the cover sheet plate 3 upward with your fingers 8 and 9 to get the size that suits you. If you want to make the face shield device the smallest for carrying around, slide the cover sheet plate 3 up to the tooth profile sponge 4 with ventilation holes.

When the user eats and drinks, it is not possible to do it in the full cover state, so when the cover sheet plate 3 is raised above the nasal cavity, there is a slightly curved notch 15 at the center end of the sheet plate, so the lips hit the cover sheet plate 3. It's difficult to eat and drink.

As another embodiment 2, FIG. 9 is provided with an opening B cut out in order to improve visibility on the upper portion of the fixed transparent plastic cover sheet plate 2. This allows the sliding face shield to be used as a transparent mouse shield.

Figure 10 is an image of the sliding face shield attached as a transparent mouse shield. Restaurant clerk, cook, and customer service staff of product sales staff need to have a good view of preventing splashes, giving a reassuring facial expression, cooking, and product selection.
The conventional transparent mouse shield prevents splashes only on the mouth, but the sliding face uses a 180-degree splash prevention and transparent plastic plate, so the facial expression can be clearly seen. In addition, since there is nothing that obstructs the view, the product can be determined. Since the size of the face differs depending on the person, the height can be adjusted to a place that does not obstruct the view. The smallest size makes it easier to carry.

For example, when watching sports, a cutout opening is provided on the upper part of the fixed transparent plastic cover sheet plate to improve visibility, so that there is no diffused reflection or cloudiness on the seat, so that good watching can be performed. As the size is smaller, it is convenient to carry, it can prevent splashes to some extent, and you can eat and drink.
