Description

  The present invention relates to a face cover for head mount display antifouling. More specifically, the present invention relates to a face cover for preventing dirt from adhering to a face pad attached to a head mounted display.

  Head mounted displays (head mounted displays) are used in virtual reality (VR) experiences and the like. As a head-mounted display, for example, a goggle-type head-mounted display that covers both eyes of the wearer is known.

  A goggle type head mounted display 100 shown in FIGS. 5A and 5B is a head mounted display in which two displays 104 corresponding to the left and right eyes of the wearer are built in a goggle type head mounted display main body 102. A pseudo-stereoscopic view is made possible by adding a parallax angle to the image on the display 104. The goggle type head mounted display 100 is used in a state of being fixed to the head of the wearer with a strap 106. Thereby, it can prevent that a head mounted display shifts from a wearer's head at the time of use.

  Furthermore, the face pad 108 (also referred to as a face cushion) is attached to the face of the goggle type head mounted display 100 that is in contact with the face of the wearer. The face pad 108 is formed of a material having flexibility and shape following properties such as low-resilience urethane, and is in close contact with the face of the wearer to improve the fit of the head mounted display to the face of the wearer. There is a function to prevent display displacement. For example, Patent Document 1 discloses that a goggle-type head-mounted display is used in a state in which a silicon rubber frame is in contact with the face or eyes on a face-contacting part that contacts the face or eyes (Patent Document 1). 1).

JP-A-8-140014 (paragraph 0003)

  As described above, the face pad enhances the fit of the head mounted display with respect to the wearer's face and exhibits an excellent function in terms of preventing the head mounted display from being displaced. However, since the face pad is a component that comes into direct contact with the wearer's face, it is inevitable that dirt such as the wearer's sweat, sebum, cosmetics, hairdressing, etc. will adhere. When dirt is attached to the face pad, it is not desirable because it causes hygiene problems such as propagation of germs from the face pad. In particular, in a situation where an unspecified number of visitors such as events and amusement facilities continuously use the head mounted display, hygiene problems such as the onset of infectious diseases become more serious.

  As a method for removing dirt adhered to the face pad, a method of wiping dirt with a wet tissue or the like is also conceivable. However, when the face pad material is a sponge material or a raised material, it is difficult to wipe off the dirt. Further, when the face pad material is urethane rubber or the like, dirt penetrates into the inside of the face pad, and simply wiping off the dirt on the surface does not solve the sanitary problem.

  As another method of removing dirt adhered to the face pad, a method of replacing the face pad itself can be considered. However, it is not practical to frequently replace the face pad from the viewpoint of cost.

  As described above, the conventional goggle type head mounted display still has a problem to be solved in that it keeps the face pad clean and hygienic and enables comfortable use.

  The present invention has been made to solve the above-described problems. In other words, an object of the present invention is to keep face pads made of various materials clean and hygienic, which can be provided at low cost and of course does not hinder stereoscopic vision by a head mounted display.

  The face cover according to the present invention is interposed between the face pad attached to the head mounted display and the face of the wearer wearing the head mounted display to prevent the face pad from being contaminated. The face cover is made of a non-woven fabric and is formed of a horizontally long rectangular cover body that can cover both eyes of the wearer, and loop-like ear hook members attached to the left and right side edges of the cover body. An opening for exposing the eyes of the wearer is formed in the cover body. The opening has a single horizontally long shape in which the right eye opening and the left eye opening of the wearer are connected to expose both eyes integrally.

  According to the present invention, the face pad attached to the head mounted display can be kept clean and sanitary without obstructing the stereoscopic vision by the head mounted display.

  Hereinafter, the face cover according to the present embodiment will be described with reference to the drawings.

[1] Function and effect:
As illustrated in FIG. 6, the face cover 1 according to the present embodiment is provided between a face pad (FIGS. 5B and 108) attached to the head mounted display main body 102 and the face of the wearer P wearing the head mounted display main body 102. Intervened in. Thus, the face of the wearer P is not directly in contact with the face pad 108, and the wearer P's sweat, sebum, cosmetics, hairdressing, and the like are less likely to adhere to the face pad 108. Accordingly, it is possible to effectively prevent sanitary problems such as the propagation of various germs from dirt adhering to the face pad 108. Further, since the face cover 1 can be used simply by being interposed between the face pad 108 and the face of the wearer P, it can be used regardless of the type of material of the face pad 108.

Moreover, the cover main body 2 which comprises the face cover 1 consists of a nonwoven fabric. Since the nonwoven fabric is an inexpensive material, the face cover 1 can be made disposable and replaced whenever it gets dirty. Thereby, the face pad can be kept clean and hygienic much cheaper than replacing the face pad itself, and the head mounted display can be used comfortably. Further, in a situation where an unspecified number of visitors such as events and amusement facilities continuously use the head mounted display, the face cover 1 can be replaced every time the wearer changes. If used in this way, it can be an effective method for solving serious health problems such as the onset of infectious diseases.
[2] Embodiment:
A face cover 1 shown in FIGS. 1A and 1B includes a cover body 2 and a loop-like ear hooking member 4.
[Cover body]
The cover body 2 is a substantially rectangular horizontally long member that is formed of a nonwoven fabric, covers both eyes of the wearer P, and has a width that does not reach both ears. The cover body 2 is formed of a non-woven fabric made of polyester. However, the material of the nonwoven fabric is not limited to polyester. For example, a nonwoven fabric in which short fibers made of a thermoplastic resin such as polyethylene and polypropylene are integrated can be used. The cover body 2 is formed of a nonwoven fabric that does not have stretchability. As a result, it is possible to effectively prevent the situation where the face cover 1 is displaced from the face of the wearer, or the face pad, and thus the head mounted display, is displaced from the surface of the face cover 1.

  The cover body 2 is a “rectangular horizontally long” cloth body having a width that covers the eyes of the wearer P integrally and a vertical width that covers a range from the lower part of the forehead to the nasal root. For example, if the width is about 200 mm, both eyes can be integrally covered for over 90% of adults regardless of gender. For example, if the vertical width is about 110 mm, it can cover from the lower forehead to the nasal root for over 90% of adults regardless of gender.

  The corner portions 3 and 5 of the upper portion 10 of the cover body 2 and the corner portions 7 and 9 of the lower portion 8 are relatively large and linearly cut off obliquely. For example, an isosceles triangle having a base of about 35 mm is cut off. ing. In other words, the upper part 10 of the cover main body 2 is formed in a shape in which the vertical width at the center portion in the left-right direction is wide and the vertical width becomes asymptotically narrower toward the outer side in the left-right direction. When the corner portions 3 and 5 of the cover body 2 are not cut off, the corner portions are separated from the face in the vicinity of the temple, but in this embodiment, the corner portions 3 and 5 of the cover body 2 are cut off. Since the main body 2 easily conforms to the shape of the wearer's forehead and the entire surface of the cover main body 2 is preferably in close contact with the face, the cover main body 2 does not cover the hair of the wearer P. Less likely to disturb the wearer's hairstyle. Therefore, a comfortable wearing feeling can be obtained.

  An opening 6 that exposes both eyes of the wearer P is opened in the cover main body 2 in a rectangular horizontally long shape in which the four corners of the rectangle are round-cut. The opening 6 has a single horizontally long shape in which the right eye opening and the left eye opening of the wearer P are connected to expose both eyes integrally. The opening 6 has its upper, lower, left and right center lines aligned with the center lines C 1 and C 2 of the cover body 2. The vertical width of the opening 6 is, for example, 35 mm, and the horizontal width is, for example, about 120 mm. With this size, both eyes can be integrally exposed to over 90% of adults regardless of gender. Note that the shape of the opening 6 is not particularly limited as long as it is an integrated opening shape that exposes both eyes of the wearer. However, the shape of the opening is not limited to such a shape, and a horizontally long shape that exposes both eyes of the wearer is sufficient. For example, an oval shape (opening 6A) as shown in FIG. 4A, an oval shape, a diamond shape (opening 6B) as shown in FIG. 4B, or the like may be adopted.

  When two openings corresponding to each of the left and right eyes are formed separately without being connected, a partition part exists between the left and right eyes, and if the partition part blocks one of the left and right eye fields of view. There is a possibility that inconsistency occurs in the images for the left and right eyes, and the stereoscopic effect is hindered. If the horizontally long opening 6 that exposes both eyes of the wearer P is integrated like the opening 6, the cover main body 2 does not block the field of view and the images on the two displays do not shift. Therefore, even if the face cover 1 is slightly deviated from the wearer P, stereoscopic viewing is not hindered without being affected by individual differences in the distance between the left and right eyes of the wearer P.

  The vertical width W2 of the upper part 10 of the cover body 2 is about 40 mm, for example. The vertical width W1 of the lower portion 8 of the cover body 2 is about 40 mm equivalent to the vertical width W2 of the upper portion 10. With the widths W1 and W2, even if the mounting position of the head mounted display main body 102 with respect to the face of the wearer P is slightly changed, the face pad 108 does not come off the cover main body 2 and the cover main body 2 is not attached to the head mounted display main body 102. Can be protected.

  The shape of the cover body 2, the shape of the opening 6, and the arrangement of the opening 6 with respect to the cover body 2 are symmetrical with respect to the center lines C 1 and C 2 both vertically and horizontally. Since the upper and lower sides and the left and right sides are symmetrical with respect to the center lines C1 and C2, the user does not need to confirm the upper and lower sides of the face cover 1 when wearing, that is, the face cover 1 is worn on the wearer P without distinction between the upper and lower sides. Can be highly convenient.

Note that the shape of the cover body 2 is not limited to a vertically symmetrical shape, and a horizontally long shape that can cover both eyes of the wearer P is sufficient. For example, as shown in FIG. 2, the cover body 2 ′ may have a horizontally long rectangular shape, a symmetrical shape with respect to the left-right center line C <b> 2, and a vertically asymmetric shape with respect to the vertical center line C <b> 2. In the example of FIG. 2, the cover body has an upper and lower width W2 of the upper portion 10 wider than an upper and lower width W1 of the lower portion 8. The upper part 10 of the cover body 2 has a vertical width W2 of about 40 mm, for example, and the lower part 8 of the cover body 2 has a vertical width W1 of about 35 mm, for example. Of the four corners of the cover body 2 ', the two corners 3, 5 of the upper portion 10 are linearly cut off obliquely to form an isosceles trapezoid. On the other hand, the corners of the lower portion 8 are rounded and are not cut off linearly and obliquely as in the upper portion 10. The lower edge of the lower part 8 is formed in a gently arcuate shape downward or a shape slightly protruding downward in an isosceles trapezoidal shape. Further, a substantially rectangular shape as shown in FIG. 3A (cover main body 3A), an ellipse as shown in FIG. 3B (cover main body 3B), a gourd type (cover main body 3C) as shown in FIG. Also good.
[Loop-shaped ear hook member]
The loop-like ear hooking member 4 is attached to the left and right side edges of the cover body 2. The loop-shaped ear hook member 4 is a member for fixing the cover body 2 in a state where the cover body 2 is in contact with the face of the wearer P. The “loop shape” is formed in an annular portion that can be hooked on the ear by integrating the cover body 2 and the loop-like ear hooking member 4 together. “Loop shape” is intended to exclude an ear hooking member in which the annular portion is not formed, such as a temple portion of glasses in a glasses-type head mounted display.

  As the loop-shaped ear hook member 4, an ear hook string is used. This ear hook string is a stretchable string member in which the surface of a rubber string serving as a core material is covered with a polyurethane nonwoven fabric. However, the loop-shaped ear hooking member is not limited to such a form. What is necessary is just to comprise suitably according to the form of the ear hook member in a conventionally well-known sanitary mask, such as using the strip | belt-shaped member which consists of a nonwoven fabric which has a stretching property, for example.

The loop-shaped ear hooking member 4 is coupled to the side edge of the cover body 2 at the joint portions 12 at both ends thereof. Typically, the loop-shaped ear hooking member 4 is coupled to the side edge of the cover main body 2 at a joint portion 12 that is vertically symmetrical with respect to the center line C1 of the cover main body 2. Thereby, it is turned upside down to enable mounting without using upside down. However, the present invention is not limited to this, and the joint portion 12 may be in a vertically asymmetric position as illustrated in FIG. In that case, the height of both ears of the wearer P with respect to both eyes varies from person to person, that is, the position of the ear may be higher or lower than the head. Individual differences can be allowed by the wearer P wearing the face cover 1 upside down appropriately.
[Production method]
The manufacturing method of the face cover of the present invention is not particularly limited. For example, the face cover 1 shown in FIGS. 1A and 1B is manufactured by the following method. As a material for the cover body 2, a non-woven polyester sheet having no stretchability was used. The nonwoven fabric sheet is cut into the horizontally long rectangular shape described above to form the cover body 2. As the loop-shaped ear hooking member 4, two stretchable string-like members in which the surface of a rubber string serving as a core material was covered with a polyurethane nonwoven fabric were used. Both ends of the string-like member are arranged on the left and right side edges of the cover body 2, and the string-like member is heated and pressure-bonded to the cover body 2, so that both ends of the string-like member are connected to the cover body 2 via the joint portion 12. Secure to the left and right side edges.
[how to use]
The face cover 1 of the present invention is used as follows. As shown in FIG. 6, the face cover 1 is applied to the face of the wearer P who wears the head-mounted display main body 102, and the loop cover 4 is hooked on both ears of the wearer P, thereby attaching the face cover 1 to the wearer. Fix to P's face. Thereafter, the position of the face cover 1 is adjusted so that the eyes of the wearer are exposed from the opening 6. The head mounted display main body 102 is placed on the face of the wearer P so that the face pad contacts the face cover 1. Thereafter, the head mounted display main body 102 is fixed to the head of the wearer P by the strap 106.

  According to the face cover 1 according to the present embodiment, even when the mounted head mounted display is displaced in the vertical direction during use, the upper part 10 absorbs the deviation and the face pad is kept in contact with the upper part 10. Can do. Therefore, the function of the face cover 1 is rarely impaired. Moreover, the substantial contact area of the face pad and the cover main body 2 can be increased by configuring the upper portion 10 that contacts the forehead of the wearer P with relatively little unevenness, so that the face cover 1 is worn by the wearer. It is possible to effectively prevent a situation in which the face pad or the head mounted display is displaced from the face of the face cover 1 or from the surface of the face cover 1.

  Although the embodiments of the present invention have been described, these embodiments are presented as examples, and are not intended to limit the scope of the device.
