The present invention relates to a face guard that protects the wearer's face.

For example, there is a face guard that protects the wearer's face from splashed materials such as water and oil.
The face guard disclosed in Patent Document 1 includes a curved body attached to the wearer's neck, a locking body attached to the curved body, and a face member covering the face. The face plate is connected to the curved body by means of a locking body.
In this face guard, since the face material extends from the wearer's face to the neck, for example, when using oil such as when cooking fried food in a food factory or at home, splashed oil will adhere to the neck. It is possible to prevent

In addition, the face guard disclosed in Patent Document 2 includes a sheet-like main body that covers the wearer's face, a base that supports the sheet-like main body so as to cover the wearer's face, and a base that supports the wearer's face. It is provided with a mounting part for mounting on a wearer. The base part is formed in a plate shape having a front surface and a rear surface, and the rear surface is configured to contact the front surface of the wearer's chest. A support portion is provided for supporting the lower end of the portion. The support portion is configured to support the sheet-like body portion so that the sheet-like body portion is inclined upward at an acute angle with respect to the front surface of the contact portion.

JP 2009-189543 A Utility Model Registration No. 3230719

In the face guard disclosed in Patent Document 1, when the wearer wears the face guard, a gap is created between the lower part of the face guard and the wearer's face. Therefore, even if this face guard is worn to prevent droplets, droplets may flow out of the face guard from the bottom when the wearer coughs or sneezes. Moreover, when a person around the wearer coughs or sneezes, there remains a problem that the droplets may enter the inside of the face guard from the lower part of the face guard.

In addition, the face guard disclosed in Patent Document 2 has a sheet-like body part that is tilted upward at an acute angle with respect to the front surface of the contact part by a support part provided on the base part. By supporting the main body, the sheet-like main body can be brought closer to the wearer's face.

However, there are cases in which, for example, in dental care, a dentist attaches a medical device (for example, a frame mirror, a frame frame microscope, etc.) to the forehead and also wears a face guard to perform treatment.
In this case, if the distance between the sheet-like main body and the wearer's face, who is a dentist, is small, the medical device or the like attached to the forehead interferes, or the face guard cannot be worn depending on the size of the medical device. There remains the problem that a case may arise.

A main object of the present invention is to provide a face guard held by the wearer's neck and capable of arbitrarily adjusting the distance from the wearer's face to the shield.

The present invention is a face guard that is held by the wearer's neck and covers the mouth and nose at a predetermined distance from the wearer's face, wherein the face guard is worn around the wearer's neck. It has an annular frame and a transparent shield that is attached to the frame and rises from the chest of the wearer. a substantially semi-annular second frame portion that contacts a person's neck, and a portion that connects the first frame portion and the second frame portion is the first frame portion with respect to the second frame portion; It is characterized by being configured as an adjustment mechanism capable of tilting and moving the shield attached to the frame portion to an arbitrary angle from the wearer's face.

ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to adjust the distance from a wearer's face to a shield arbitrarily.

Embodiments of the present invention will be described below with reference to the drawings.

[Embodiment example]
FIG. 1 is a schematic diagram for explaining an example of the configuration of the face guard according to this embodiment.
The face guard 100 is held by the neck of the wearer (see FIG. 9, etc.) and is a face guard that covers the mouth and nose at a predetermined distance from the wearer's face.
As shown in FIG. 1, the face guard 100 has a substantially annular frame 20 that is worn around the wearer's neck, and a transparent shield 10 that is attached to the frame 20 and rises from the wearer's chest.
For example, the shield 10 is made of polyethylene terephthalate (PET) and the frame 20 is made of ABS resin containing an antibacterial agent. These used materials are examples, and can be arbitrarily combined according to the purpose of use of the face guard 100 and other circumstances.

2, 3(a), (b), and (c) are diagrams for explaining an example of the configuration of the frame 20 of the face guard 100. FIG.
FIG. 2 is a perspective view showing the overall appearance of the frame 20. As shown in FIG. 3A is a top view of the frame 20, FIG. 3B is a front view, and FIG. 3C is a rear view.

The frame 20 has a substantially semi-annular first frame portion 201 to which the shield 10 is attached, and a substantially semi-annular second frame portion 202 that contacts the wearer's neck.
As shown in FIG. 2, the first frame portion 201 is formed with a convex portion 201a that serves as positioning when the shield 10 is attached to the first frame portion 201. As shown in FIG. The details of positioning will be described later.

The portion where the first frame portion 201 and the second frame portion 202 contact (connection portion) is based on the second frame portion 202, and the shield 10 attached to the first frame portion 201 is attached to the wearer's face. to an arbitrary angle (see FIGS. 4, 8, and 9 to be described later).

The adjustment mechanism of the face guard according to this embodiment is composed of a screw structure 204, a plate-like portion 202a formed at each of the two ends of the second frame portion 202, and a groove portion 202b formed in the plate-like portion 202a. be done.

The adjustment mechanism presses the end portion of the first frame portion 201 and the plate-like portion 202a of the second frame portion 202 into contact with each other by means of a screw structure 204, which is a combination of male and female screws, for example. This restricts the movement of the shield 10 relative to the frame 20 (second frame portion 202), or releases the pressure contact, thereby allowing the shield 10 to move.
In this way, it is possible to regulate the movement of the shield 10 relative to the frame 20 (second frame portion 202) or release the regulation by simply “tightening” and “loosening” the screws. Become.

The screw structure 204 is an example of a structure for pressing the end portion of the first frame portion 201 and the plate-like portion 202a of the second frame portion 202 into contact with each other. Configurations can also be employed. Also, any configuration may be used as long as it is possible to restrict the movement of the shield 10 relative to the frame 20 (second frame portion 202) or release the restriction.

In addition, the adjustment mechanism functions as a mechanism capable of freely moving the shield 10 attached to the first frame portion 201 back and forth from the wearer's face with reference to the second frame portion 202 (described later). 5, 8 and 9). Details will be described later.

As shown in FIG. 3A, the second frame portion 202 is formed by protruding two predetermined portions (position D in the figure) toward the center. For example, the dashed circle shown in FIG. 3(a) schematically shows an example of the size (diameter) of the wearer's neck. The size (diameter) of the wearer's neck varies depending on the physique of a man, a woman, an adult, a child, and so on. Therefore, by providing the projecting portion, it is possible to increase the range of subjects that can be used without impairing the fit.

The portion of the second frame portion 202 where the projecting portion is provided (for example, position D in the drawing) can be arbitrarily set, and the amount (size) of projection can be arbitrarily set according to the prospective user. Can be set.

FIG. 4 is a side view for explaining an example of the tilting motion of the frame 20. FIG.
As described above, the adjusting mechanism is attached to the first frame portion 201 with the second frame portion 202 as a reference at the portion where the first frame portion 201 and the second frame portion 202 contact (connecting portion). It is a mechanism capable of tilting and moving the shield 10 at an arbitrary angle from the wearer's face.

As shown in FIG. 4, the first frame portion 201 can be pivoted around the screw arrangement 204 as a rotation axis. As a result, the shield 10 is tilted according to the rocking movement of the first frame portion 201, and the wearer can freely adjust the angle according to his/her preference and usage conditions while keeping the fit of the second frame portion 202 as it is. It is possible to tilt the shield 10 to

FIG. 5 is a side view for explaining an example of the expansion and contraction (back and forth) motion of the frame 20. As shown in FIG.
As described above, the adjustment mechanism is also a mechanism capable of freely moving the shield 10 attached to the first frame portion 201 back and forth from the wearer's face with the second frame portion 202 as a reference. be.

The first frame portion 201 can be moved forward from the state of FIG. 5(a) to the state of FIG. 5(b), and further from the state of FIG. 5(b) to the state of FIG. 5(c). 5(c) to the state of FIG. 5(b), and further from the state of FIG. 5(b) to the state of FIG. 5(a).

As a result, the shield 10 moves in accordance with the forward and backward movement of the first frame portion 201, and the wearer wears the shield 10 according to his/her preference and usage conditions while maintaining the fit of the second frame portion 202. It is possible to arbitrarily adjust the distance from the person's face.

6A and 6B are diagrams for explaining an example of the configuration of the shield 10 of the face guard 100. FIG. 6A is a plan view of the shield 10, and FIG. 6B is a diagram showing the thickness of the shield 10. FIG.
For example, for the purpose of preventing droplet infection in dental care, which will be described later, if the shape of the shield is a wide shape directed from the bottom to the top, the thickness of the shield should be 0.2 [mm] or more to 1.0 [mm] or more. mm] or less.
The shield 10 has a hole portion 101 a corresponding to the positioning protrusion 201 a when attached to the first frame portion 201 , and a hole portion 101 b communicating with the first frame portion 201 via a screw arrangement 204 .
The planar view size, shape, and thickness t (FIG. 6B) of the shield 10 can be arbitrarily set according to the purpose of use of the face guard 100 and other circumstances.

For example, the shield 10 can be formed in a shape such that the width of the shield 10 when attached to the first frame portion 201 when viewed from the front increases from the bottom to the top. Specifically, by increasing the area of width F with respect to width L shown in FIG.

The width of the shield 10 in the width L of the shield 10 is defined by the width of the hole portion 101b, the screw structure 204, and the width of the first frame portion 201. force) is regulated and its shape is maintained.
On the other hand, in the area of the width F, the restoring force of the shield 10 (the force to return to the plate shape) acts and spreads according to the size of the area of the width F, and the width size of the shield 10 in the front view is increased. It becomes a wide shape directed from the bottom to the top.

Further, as shown in FIG. 6A, the hole portions 101a and 101b are set according to the convex portion 201a of the first frame portion 201 and the hole portion (not shown) corresponding to the screw structure 204. can be done. In this embodiment, in order to correspond to the first frame portion 201, the shield 10 is formed with an interval of height H when viewed from above.

As in the present embodiment, by forming the hole 101b at a relatively high position with respect to the hole 101a, the shield 10 can be easily attached to the first frame 201 and the face guard 100 can be worn. It is possible to improve the sense of stability when a person wears it, that is, the so-called goodness of sitting.
Also, the shape of the first frame portion 201 has a region formed in a substantially V-shape when viewed from the front. A predetermined portion of the first frame portion 201 including this area comes into contact with the shield 10 .
In this way, the first frame portion 201 having the region formed in a substantially V-shape as described above is important for stably maintaining the wide shape of the shield 10 directed upward from below. It is meaningful.

FIGS. 7 and 8 are side views for explaining an example of the tilting motion and the stretching (back and forth) motion of the face guard 100. FIG.
The wearer can incline the shield 10 at an arbitrary angle or set the distance between the shield 10 and the wearer's face according to his/her preference and usage conditions while keeping the fit of the second frame portion 202 as it is. can be adjusted. By combining the tilting movement and the back-and-forth movement, it is possible to determine the position of the face guard 100 according to the wearer's preference and usage conditions.

9, 10, and 11 are side views for explaining an example of a state in which the wearer wears the face guard.
The hatched arrows shown in each figure schematically show droplets when a person around the wearer coughs or sneezes. In the face guard 100 according to this embodiment, as described above, by combining the tilting movement and the back-and-forth movement, it is possible to determine the position of the face guard 100 according to the wearer's usage conditions. Therefore, it is possible to more effectively prevent droplets from entering the inside of the face guard 100 from the lower part of the face guard 100 .

For example, in dental care, a dentist often treats a patient who is lying on an examination table with his or her line of sight lowered (in a state of looking down). The face guard 100 according to this embodiment can effectively prevent droplets from entering even when the patient coughs or sneezes in such a situation.

Further, for example, in dental care, a dentist may attach a medical device (for example, a microscope device) to the forehead and further wear a face guard to perform treatment. With the face guard 100 according to this embodiment, even in such a situation, it is possible to effectively prevent interference between the inner surface of the shield 10 and the medical device or the like worn by the dentist on the forehead. . Of course, the degree of freedom in the size of the medical device that can be worn on the forehead by the dentist is greatly increased, and the device can be easily attached and detached.

FIG. 12 is a schematic diagram for explaining an example of the configuration of the pair of projections 202c provided on the second frame portion 202. As shown in FIG. FIG. 12(a) is a top view, and FIG. 12(b) is a rear view.
As shown in FIG. 12, the second frame portion 202 can also form a pair of protrusions 202c extending outward from respective portions at positions opposed in the width direction thereof.
Also, the portion on the second frame portion 202 where the protrusion 202c is formed may be a projecting portion of the second frame portion.

As shown in FIG. 12A, the projecting body 202c functions as positioning (preventing falling off) when the elastic body (for example, rubber cord) 300 is attached to the second frame part 202. As shown in FIG.
By attaching the elastic body 300 to the second frame portion 202, it is possible to further increase the width of the subject who can be used without impairing the fitting feeling of the second frame portion 202 described above. Furthermore, the elastic force of the elastic body 300 enables adjustment of the width size of the second frame portion 202 (in the direction of the arrow in FIG. 12, etc.). In this way, it is possible to wear the second frame portion 202 (face guard 100) with a feeling of fit according to preference.

13A and 13B are schematic diagrams for explaining an example of the configuration of a dividing mechanism that divides the second frame portion 202 into two. FIG. 13(a) is a top view, and FIG. 13(b) is a rear view.
As shown in FIG. 13, a splitting mechanism 202d for splitting the second frame portion 202 into two can also be provided. For example, the splitting mechanism 202d can be configured using magnets or by fitting concave and convex portions. This makes attachment and detachment of the face guard 100 easier.

FIG. 14 is a reference diagram showing a usage example of the face guard 100. As shown in FIG.
In FIG. 14, it can be seen that the dentist is wearing a medical device such as a forehead mirror or a forehead microscope, and wearing the face guard 100 in such a situation.

Thus, in the face guard 100 according to this embodiment, the distance from the wearer's face to the shield 10 can be arbitrarily adjusted.
Specifically, the wearer can incline the shield 10 at an arbitrary angle according to his/her preference and usage conditions while maintaining the fit of the second frame portion 202 . In addition, the wearer can arbitrarily adjust the distance between the shield 10 and the wearer's face according to his/her preference and usage conditions while keeping the fit of the second frame portion 202 as it is. Furthermore, by combining the tilting movement and the back-and-forth movement, it is possible to determine the position of the face guard 100 in accordance with the usage conditions of the wearer.

Therefore, by adjusting the distance between the shield and the face (forehead) according to the situation in which the face guard 100 is used, for example, when a doctor wearing the face guard 100 uses a forehead mirror or a forehead microscope, these The equipment can be easily attached and detached, and the equipment can be guarded during use.

The embodiments described above are for more specifically describing the present invention, and the scope of the present invention is not limited to these examples.
