Description

The present disclosure relates to an ultraviolet irradiator for eyewear.

As an ultraviolet irradiator for irradiating eyewear with ultraviolet rays, there is a spectacle case described in Japanese Patent Laid-Open No. 10-85022. The spectacle case includes an upper case and a lower case connected to the upper case via a hinge. The upper case has a pair of lamps provided on its inner surface. Glasses are accommodated in the lower case. The pair of lamps irradiate the spectacles accommodated in the lower case with ultraviolet light while the upper case is closed with respect to the lower case.

JP-A-10-85022

In a case such as the eyeglass case described above, an upper case having a pair of lamps for irradiating ultraviolet rays and a lower case accommodating eyewear are integrated. Therefore, before irradiating the eyewear with ultraviolet rays, the upper case is opened and the eyewear is placed on the lower case. need to take out. Therefore, it is necessary to take the eyewear in and out of the case when irradiating the eyewear with ultraviolet rays. Furthermore, in the case of the UV irradiator integrated with the case as described above, depending on the size or shape of the eyewear, the eyewear may not fit in the case, and there is a problem that a separate dedicated case must be prepared. Therefore, there is room for improvement in terms of the usability of the ultraviolet irradiator for eyewear and the fact that the ultraviolet irradiator for eyewear cannot be used for various types of eyewear.

An object of the present disclosure is to provide an ultraviolet irradiation device for eyewear that is easy to use and can be used for various types of eyewear.

The ultraviolet irradiation device for eyewear according to the present disclosure is an ultraviolet irradiation device for eyewear that irradiates ultraviolet rays onto eyewear. The ultraviolet irradiator for eyewear has a cover part for covering the eyewear placed on the placing part, a housing separate from the placing part, and the eyewear covered with the cover part. and an irradiating element for irradiating ultraviolet rays from a direction intersecting the front extending surface on which the front of the eyewear extends.

In addition, the drawings are partially simplified or exaggerated for easy understanding, and the dimensional ratios and the like are not limited to those described in the drawings.

In the present disclosure, "eyewear" refers to a device that is worn over the wearer's eyes. "Eyewear" includes spectacles that correct refractive errors of the eyes such as myopia, hyperopia or astigmatism, sunglasses that decorate the periphery of the eyes, goggles that protect the eyes, and the like. In this embodiment, the eyewear is irradiated with ultraviolet rays. "Ultraviolet" indicates light with a wavelength of 10 nm or more and 420 nm or less. The lower limit of the "ultraviolet" wavelength band may be 100 nm, 150 nm, 200 nm, 250 nm or 300 nm. Also, the upper limit of the wavelength band of "ultraviolet rays" may be 400 nm, 380 nm or 350 nm. The "ultraviolet" wavelength band may include part of the visible light wavelength band. There are various purposes for irradiating the eyewear with ultraviolet rays. The purpose of irradiating the eyewear with ultraviolet rays is, for example, sterilization, but it may be anti-fogging, and is not particularly limited.

The eyewear has a front facing forward of the wearer when the eyewear is worn by the wearer. Front indicates the portion of the eyewear that is positioned in front of the wearer wearing the eyewear. The front is, for example, a portion including a pair of lenses, a pair of rims surrounding each of the pair of lenses, and a bridge connecting the pair of rims to each other. In the present disclosure, ultraviolet light is applied from a direction that intersects the front extending surface on which the front extends. The front extending surface indicates a virtual surface extending along the front. The front extending surface represents, for example, a virtual surface extending along a pair of lenses, a pair of rims, and a bridge.

The eyewear is placed on the placement section. In the present disclosure, the "placement part" indicates the part or place where the eyewear is placed when using the ultraviolet irradiator for eyewear. A "placement" includes any part on which eyewear is placed, such as, for example, a floor, table, desk, or shelf. The “placement portion” may be a flat surface, or may be a portion having unevenness at least partially.

FIG. 1 is a plan view showing an ultraviolet irradiation device 1 for eyewear according to an embodiment. FIG. 2 is a perspective view of the ultraviolet irradiation device 1 for eyewear as viewed from above. FIG. 3 is a perspective view of the ultraviolet irradiation device 1 for eyewear as viewed from below. As shown in FIGS. 1 and 2, the ultraviolet irradiator 1 for eyewear is separate from the mounting portion S, and is used while being mounted on the mounting portion S. As shown in FIGS. In the present embodiment, an example in which the mounting portion S extends substantially horizontally and the ultraviolet irradiation device 1 for eyewear is placed on the mounting portion S will be described.

An eyewear ultraviolet irradiation device 1 includes a housing 2 . The housing 2 is made of plastic, for example. In this case, the portability of the housing 2 is improved. However, the material of the housing 2 is not particularly limited and may be a material other than plastic, such as metal. The housing 2 is separate from the mounting section S. As shown in FIG. The housing 2 has a cover portion 3 and a power supply portion 4 . The configuration of the housing 2 of the ultraviolet irradiation device 1 for eyewear according to the present embodiment will be described below with reference to FIGS. 1 to 3. FIG.

The housing 2 has, for example, a substantially hexahedral shape with rounded corners. The mounting portion S is, for example, a plane extending in a first direction D1 and a second direction D2 intersecting the first direction D1. The first direction D1 and the second direction D2 are, for example, orthogonal to each other. In the present embodiment, the first direction D1 is the longitudinal direction of the housing 2 and the second direction D2 is the lateral direction of the housing 2 . The housing 2 has a lower surface 2A facing the mounting portion S along a third direction D3 orthogonal to both the first direction D1 and the second direction D2. In the present embodiment, the third direction D3 is a direction that intersects (perpendicularly as an example) the placement section S. As shown in FIG. In the present embodiment, the direction in which the housing 2 is provided when viewed from the placement section S is defined as "upper", "upper" or "upper", and the opposite direction is defined as "lower", "lower" or "lower". explain. However, these directions are for convenience of explanation, and do not limit the direction in which the ultraviolet irradiation device 1 for eyewear is arranged.

The housing 2 has upper surfaces 2B and 2C facing away from the lower surface 2A. The housing 2 has a side surface 2D extending along a plane orthogonal to the second direction D2 and a side surface 2F facing the opposite side to the side surface 2D. The housing 2 has a pair of side surfaces 2E facing each other. Each side surface 2E extends, for example, along a plane orthogonal to the first direction D1. The lower surface 2A and the upper surfaces 2B, 2C are connected to each other through the side surfaces 2D, 2E, 2F. In the present embodiment, as the direction along the second direction D2, the side on which the side surface 2D is located may be referred to as the front side, and the side on which the side surface 2F is located may be referred to as the back side. However, these directions are for convenience of explanation, and do not limit the direction in which the housing 2 is arranged. As an example, the power supply unit 4 is positioned closer to the front side than the cover unit 3 .

The housing 2 has a rectangular shape in plan view (when viewed from above). In plan view, the housing 2 has long sides 21 and 22 extending along the first direction D1 and a pair of short sides 23 extending along the second direction D2. The lower surface 2A includes a lower surface 4A of the power supply unit 4, a lower surface 31A of the cover unit 3, and a recess 6 positioned between the lower surface 4A and the lower surface 31A and extending along the first direction D1. As an example, the lower surface 4A, the recessed portion 6, and the lower surface 31A are arranged in this order along the second direction D2 from the near side toward the far side.

4 A of lower surfaces and 31 A of lower surfaces exhibit rectangular shape, for example. The lower surface 4A has long sides 21, 61 extending along the first direction D1 and a pair of short sides 23A extending along the second direction D2. The lower surface 31A has long sides 22, 62 extending along the first direction D1 and a pair of short sides 23B extending along the second direction D2. The recess 6 is recessed with respect to the lower surfaces 4A and 31A. For example, the recess 6 has a bottom surface 6A and a pair of inner side surfaces 6B extending from the bottom surface 6A to each of the lower surfaces 4A and 31A. The long side 61 is a boundary line connecting the lower surface 4A and one inner side surface 6B to each other. The long side 62 is a boundary line connecting the lower surface 31A and the other inner side surface 6B to each other. The recess 6 extends, for example, from one end of the housing 2 in the first direction D1 to the other end.

The top surface 2</b>B and the side surface 2</b>D correspond to surfaces forming the power supply unit 4 . As an example, the upper surface 2B has a rectangular shape. The upper surface 2B has, for example, long sides 24 and 25 extending along the first direction D1 and a pair of short sides 26 extending along the second direction D2. In this embodiment, the upper surface 2B extends along a plane intersecting (perpendicular to) the third direction D3. For example, the upper surface 2B extends parallel to the mounting portion S.

The side surface 2</b>D is located on the front side of the housing 2 . As an example, the side surface 2D has a rectangular shape. Side surface 2D connects lower surface 2A and upper surface 2B to each other. As an example, the side surface 2D is orthogonal to each of the lower surface 2A and the upper surface 2B. The side surface 2D corresponds to a surface rising from the mounting portion S. As shown in FIG. For example, the side surface 2D extends perpendicularly to the mounting section S. As shown in FIG.

The top surface 2</b>C and the side surface 2</b>F correspond to surfaces that form the cover portion 3 . A boundary portion between the top surface 2C and the side surface 2F can be the vertex of the housing 2 provided at the farthest position from the mounting portion S.

The upper surface 2C extends diagonally with respect to the upper surface 2B of the power supply unit 4 (so as to extend obliquely upward from the upper surface 2B). As an example, the upper surface 2C has a rectangular shape. The upper surface 2</b>C has long sides 25 and 27 extending along the first direction D<b>1 and a pair of short sides 28 extending obliquely with respect to the mounting portion S. 2 C of upper surfaces are located above 31 A of lower surfaces, for example. The long side 27 is provided at a position spaced apart from the lower surface 31</b>A more than the long side 25 , that is, above the long side 25 . The long side 25 is a boundary line connecting the upper surface 2B and the upper surface 2C. For example, the top surface 2C extends from the long side 25, which is the boundary line with the top surface 2B, toward the long side 27 toward the back side and obliquely upward.

The side surface 2</b>F is located on the back side of the housing 2 . Side surface 2F extends from long side 27 to long side 22 . The side surface 2F connects the lower surface 2A and the upper surface 2C to each other. In this embodiment, when the housing 2 is viewed along the first direction D1, the angle formed by the side surface 2F and the bottom surface 2A is smaller than 90 degrees. The side surface 2F is inclined with respect to the third direction D3 when viewed from the first direction D1. The long side 27 is a boundary line connecting the side surface 2F and the top surface 2C. The long side 22 is a boundary line connecting the side surface 2F and the bottom surface 2A. The side surface 2F extends obliquely upward from the long side 22 forming the lower surface 2A toward the long side 27 forming the upper surface 2C.

Each of the pair of side surfaces 2E connects the lower surface 2A and the upper surfaces 2B, 2C to each other. The pair of short sides 23 are boundary lines that connect the bottom surface 2A and the side surfaces 2E to each other. The short side 26 is a boundary line connecting the top surface 2B and the side surfaces 2E. The short side 28 is a boundary line connecting the upper surface 2C and the side surfaces 2E. As an example, each side surface 2E is orthogonal to the lower surface 2A and the upper surfaces 2B, 2C. For example, the pair of side surfaces 2E extend perpendicularly to the mounting portion S.

The housing 2 according to the present embodiment includes, for example, a lower portion 20A facing downward (toward the mounting portion S) when placed on the mounting portion S, and a lower portion 20A facing upward (toward the side opposite to the mounting portion S). and an upper portion 20B. In the housing 2, for example, an upper portion 20B and a lower portion 20A are separable from each other.

As an example, the housing 2 can be divided into a lower portion 20A and an upper portion 20B via dividing lines 2G, 2H, 2J, and 2K formed on the side surfaces 2D, 2F, and 2E, respectively. For example, the housing 2 may have a lower portion 20A and an upper portion 20B that are separate from each other and are joined together by screwing. Further, the housing 2 may be configured by bonding the lower portion 20A and the upper portion 20B to each other, or may be configured by fitting the lower portion 20A and the upper portion 20B to each other. Thus, there is no particular limitation on the joining means between the lower portion 20A and the upper portion 20B. Furthermore, the housing 2 may be configured in one body, and the number of parts of the housing 2 is not particularly limited.

For example, the parting line 2G is arranged on the side surface 2D and extends from one end to the other end of the housing 2 in the first direction D1. As an example, the dividing line 2G extends along the first direction D1. For example, a pair of dividing lines 2J are arranged on a pair of side surfaces 2E, and each dividing line 2J extends from both ends of the dividing line 2G toward the inner side. As an example, the pair of dividing lines 2J extend along the second direction D2.

For example, the parting line 2H is arranged on the side surface 2F located on the back side of the housing 2 and extends from one end to the other end of the housing 2 in the first direction D1. As an example, the dividing line 2H extends along the first direction D1. For example, a pair of dividing lines 2K are arranged on a pair of side surfaces 2E, and each dividing line 2K extends forward from each of both ends of the dividing line 2H. As an example, the pair of dividing lines 2K extend along the upper surface 2C. On the side surface 2E, the end of each dividing line 2J is continuous with the end of each dividing line 2K.

As described above, the housing 2 has the cover portion 3 and the power supply portion 4 . In a plan view, the power source section 4 is adjacent to the cover section 3 . The power supply unit 4 and the cover unit 3 are adjacent to each other along the second direction D2. As an example, the power supply unit 4 has a rectangular parallelepiped shape. For example, the cover portion 3 has a triangular prism shape extending in the first direction D1 and includes an upper surface 2C extending obliquely upward from the power supply unit 4 and a side surface 2F extending obliquely downward from the upper end of the upper surface 2C. The power supply unit 4 is a part including a power supply 41 . In this embodiment, the power source 41 may be a dry battery or a rechargeable battery. The power supply 41 may be a converter that converts household power.

The power supply unit 4 has a switch 5 and a notification unit 51 . The switch 5 and the notification unit 51 are located, for example, on the upper surface 2B. The switch 5 and the notification section 51 are exposed on the surface of the housing 2 when the housing 2 is placed on the mounting portion S. As shown in FIG. FIG. 4 is a block diagram showing the configuration of the circuit board 8 having the switch 5, the power source 41, the control section 52, the irradiation element 7 and the notification section 51 of the ultraviolet irradiation device 1 for eyewear. The irradiation element 7 is an element that irradiates the eyewear with ultraviolet rays. The irradiation element 7 is, for example, an ultraviolet LED (Light Emitting Diode). The irradiation element 7 will be described later in detail.

The circuit board 8 includes, for example, a controller 52 that controls irradiation of ultraviolet rays by the irradiation element 7 . As an example, the circuit board 8 is fixed to the housing 2 with screws. The circuit board 8 may be a single board, or may include a plurality of boards electrically connected to each other. As an example, the circuit board 8 may be composed of a control board (not shown) and an irradiation board (not shown). For example, the control board includes the switch 5 , the notification section 51 , the control section 52 and the power supply 41 . For example, the irradiation substrate is arranged on the cover part 3 and comprises a pair of irradiation elements 7 .

The irradiation element 7 , the switch 5 and the power supply 41 are electrically connected to each other via the control section 52 . A power supply 41 supplies power to the irradiation element 7 . The control unit 52 controls irradiation of ultraviolet rays from the irradiation element 7 . The intensity of the ultraviolet rays irradiated to the eyewear E by the irradiation element 7 is, for example, constant, and may be determined in advance through experiments, simulations, or the like. Further, the intensity of the ultraviolet rays may be variable, an adjusting means capable of adjusting the intensity of the ultraviolet rays may be provided, or the controller 52 may automatically control the intensity of the ultraviolet rays. For example, after the switch 5 is operated, the control unit 52 causes the irradiation element 7 to emit ultraviolet rays until a certain period of time (for example, 10 seconds or more and 10 minutes or less) has passed, and after the certain period of time has passed, the ultraviolet rays are emitted. may be stopped.

The time during which the irradiation element 7 irradiates ultraviolet rays may be constant as described above, or may be determined in advance by experiments, simulations, or the like, similar to the intensity of ultraviolet rays. In addition, the ultraviolet irradiation time may be variable, an adjusting means for adjusting the ultraviolet irradiation time (lighting time) may be provided, or the control unit 52 may automatically control the ultraviolet irradiation time. may be controlled.

The notification unit 51 is connected to the control unit 52, for example. Under the control of the control unit 52, the notification unit 51 notifies the user of the ultraviolet irradiation device 1 for eyewear whether or not the irradiation element 7 is irradiating ultraviolet rays. The notification unit 51 is, for example, a lamp (LED as an example) that lights up when the irradiation element 7 is irradiating ultraviolet rays. Further, when the power source 41 is a dry cell or a rechargeable battery, the eyewear ultraviolet irradiator 1 may be provided with a remaining amount reporting means for reporting the remaining amount of the power source 41 in the same manner as the reporting unit 51 .

FIG. 5 is a partial cross-sectional view showing the ultraviolet irradiation device 1 for eyewear cut along a plane extending in both the second direction D2 and the third direction D3. FIG. 6 is a partial cross-sectional view of the ultraviolet irradiator 1 for eyewear used in a manner different from that in FIG. The configuration of the ultraviolet irradiator 1 for eyewear and the positional relationship between the ultraviolet irradiator 1 for eyewear and the eyewear E will be described below with reference to FIGS. 5 and 6. FIG.

As shown in FIG. 5, the eyewear ultraviolet irradiation device 1 covers the eyewear E placed on the placement part S. As shown in FIG. The eyewear E has a front E3 including a portion of the frame E1 and a pair of lenses E2 fixed to the frame E1. The frame E1 includes a pair of hinges E4 provided at both ends of the front E3, and a pair of temples E5 extending from each hinge E4 in a direction crossing the front E3. The front E3 has a pair of rims (not shown) surrounding the lens E2, a bridge (not shown) connecting the pair of rims together, and a pair of pads (not shown) attached to the bridge.

The eyewear E is placed on the placement section S with the pair of temples E5 folded, for example. As an example, the pair of temples E5 is folded so as to be adjacent to the pair of lenses E2 by closing the pair of hinges E4. In this case, each temple E5 faces each lens E2 along the third direction D3. For example, the eyewear E is placed so that the pair of hinges E4 and the pair of folded temples E5 are in contact with the placement portion S. The front E3 is positioned above a pair of hinges E4 and a pair of folded temples E5. The eyewear E is placed so that the front E3 faces upward (for example, obliquely upward with respect to the placing section S).

As an example different from FIG. 5, the eyewear E may be placed on the placing portion S in a state in which the temples E5 are not folded. Thus, the mode of placing the eyewear E on the placing portion S is not particularly limited.

The front E3 extends along the front extension plane FS. The front extension surface FS is a surface including the pair of lenses E2 and at least part of the frame E1. The front extending surface FS is a virtual surface (flat or curved surface) extending along the front E3 of the placed eyewear E when the eyewear E is placed on the placing portion S. As an example, the eyewear E is placed so that the front extending surface FS extends along the first direction D1. The front extension surface FS may be inclined with respect to the placement section S. As an example, the front extension surface FS is inclined obliquely upward (so as to increase the distance from the mounting section S) from the near side toward the far side.

The angle formed by the front extending surface FS and the mounting portion S is, for example, 20 degrees or more and 75 degrees or less. The angle formed by the front extending surface FS and the mounting portion S may be 30 degrees or more, 40 degrees or more, or 45 degrees or more. Further, the angle formed by the front extending surface FS and the mounting portion S may be 70 degrees or less, 60 degrees or less, or 50 degrees or less. As an example, the angle formed by the front extending surface FS and the mounting portion S is 35 degrees. Note that the front extension surface FS does not have to be inclined with respect to the placement portion S. The front extension surface FS may be parallel to the mounting portion S or may be perpendicular to the mounting portion S. The angle of the front extending surface FS with respect to the mounting portion S may be 0 degrees or more and 90 degrees or less, and can be changed as appropriate.

The configuration of exemplary eyewear E has been described above. However, the configuration of the eyewear E is not limited to the example described above. Furthermore, the eyewear ultraviolet irradiator 1 can cover various types of eyewear other than the eyewear E. FIG.

The cover part 3 corresponds to a part that covers the eyewear E. As shown in FIG. In this embodiment, the cover portion 3 has inner surfaces 3A, 3B, 3C, and 3D facing the eyewear side. For example, the inner surface 3A is a surface extending obliquely with respect to the mounting portion S and faces the front E3 of the eyewear E. As shown in FIG. The inner surface 3A extends along the front extension surface FS, and as an example, extends along a direction parallel to the front extension surface FS. The inner surface 3B faces the back side, and the inner surface 3C faces the front side. A pair of inner surfaces 3D are opposed to each other in the first direction D1. The inner surface 3B and the inner surface 3C are connected to each other via each inner surface 3D. The inner surfaces 3A, 3B, 3C, and 3D define, for example, a hexahedral inner space together with the mounting portion S.

The inner surface 3A is located on the back side of the upper surface 2C. As an example, the inner surface 3A has a rectangular shape. The inner surface 3A extends along the upper surface 2C. The inner surface 3A has long sides 32 and 33 extending along the first direction D1, and a pair of short sides 34 (see FIG. 3) extending from the long side 32 to the long side 33 . The long side 33 is provided at a position spaced apart from the lower surface 31</b>A more than the long side 32 , that is, above the long side 32 . The long side 33 is a boundary line connecting the inner surface 3A and the inner surface 3C. The long side 32 is a boundary line connecting the inner surface 3A and the inner surface 3B.

The inner surface 3C is located on the back side of the side surface 2F. As an example, the inner surface 3C has a rectangular shape. The inner surface 3C extends along the side surface 2F. For example, the inner surface 3C extends from the long side 33 toward the bottom surface 31A toward the back side and obliquely downward. The inner surface 3C is inclined with respect to the mounting portion S.

The inner surface 3B is located on the opposite side to the inner surface 3C. As an example, the inner surface 3B has a rectangular shape. For example, the inner surface 3B extends perpendicularly to the mounting portion S. As an example, the inner surface 3B extends along a plane perpendicular to the second direction D2.

A pair of inner surfaces 3D are located behind the pair of side surfaces 2E. Each inner surface 3D extends along each side surface 2E. As an example, the pair of inner surfaces 3D extend along a plane perpendicular to the first direction D1.

In this embodiment, the inner surface 3A has openings 35 . An irradiation element 7 is arranged inside the opening 35 . For example, a pair of openings 35 are formed in the inner surface 3A, and the irradiation element 7 is arranged in each opening 35 . The irradiation element 7 irradiates the eyewear E covered with the cover portion 3 with the ultraviolet rays L. The irradiation element 7 irradiates the ultraviolet rays L from a direction intersecting the front extension surface FS. The irradiation element 7 is provided at a position facing the lens E2 of the eyewear E placed on the placement portion S, for example. As an example, a pair of irradiation elements 7 is positioned in front of each lens E2, and irradiates the lens E2 with ultraviolet light L from a direction intersecting (perpendicular to, for example) the front extending surface FS.

For example, the inner surfaces 3A, 3B, 3C, and 3D of the cover portion 3 facing the eyewear side are made of a reflective material that reflects ultraviolet rays. The reflector may be made of a material having a higher UV reflectance than the material of the housing 2 . The reflector may be, for example, a mirror that reflects ultraviolet rays. As an example, the mirror may be a glass mirror in which a metal film is vapor-deposited on glass, or a metal mirror in which metal is polished. Further, the reflector may be, for example, a reflector that diffusely reflects ultraviolet rays. As an example, the reflector may be a white material or a metallic material. In this manner, the type of reflective material of the cover portion 3 can be changed as appropriate.

As an example, the inner surface 3C located on the far side may be made of the reflecting material. In this case, of the ultraviolet rays L emitted from the irradiation element 7, the ultraviolet rays L emitted to the inner surface 3C but not to the eyewear E can be reflected to the eyewear E from the inner surface 3C. However, the position, size and number of reflectors that reflect the ultraviolet rays L are not particularly limited. For example, all of the inner surfaces 3A, 3B, 3C and 3D may be made of the reflecting material, or some of the inner surfaces 3A, 3B, 3C and 3D may be made of the reflecting material.

The cover portion 3 has an edge 31 facing the mounting portion S. As shown in FIG. The edge 31 defines an opening of the cover portion 3 that covers the eyewear E. As shown in FIG. The edge 31 is a portion including the lower surface 31A. The edge 31 has a first portion (the right portion in FIG. 5) including the inner surface 3C and the side surface 2F, and a second portion (the left portion in FIG. 5) including the inner surface 3B and the inner surface 6B. Furthermore, it has a pair of third portions that connect the first portion and the second portion together and include an inner surface 3D and a side surface 2E.

The housing 2 has an inclined portion 9 that is inclined with respect to the mounting portion S and along the front extension surface FS. The inclined portion 9 is, for example, a portion including the upper surface 2C and the inner surface 3A described above. The irradiation element 7 is arranged on the inclined portion 9 . The inclined portion 9 is positioned above the cover portion 3 . The slanted portion 9 is slanted so that the distance from the placement portion S increases from the near side toward the far side. The inclination angle of the inclined portion 9 with respect to the mounting portion S is, for example, 20 degrees or more and 75 degrees or less. However, the inclination angle of the inclined portion 9 with respect to the mounting portion S can be appropriately changed, like the angle between the front extending surface FS and the mounting portion S described above.

As shown in FIG. 6, the cover part 3 may cover the eyewear E housed in the eyewear case C. As shown in FIG. As an example, the eyewear case C has a rectangular parallelepiped shape. The eyewear case C includes a lower case C1 that accommodates the eyewear E and an upper case C2 that covers the eyewear E accommodated in the lower case C1.

The lower case C1 has an opening facing upward. For example, the width of the opening of the cover part 3 (the length in the second direction D2) is wider than the width of the opening of the lower case C1. Thereby, the opening of the lower case C1 can be reliably closed by the cover portion 3 . In the example of FIG. 6, the cover part 3 functions as a part that covers the lower case C1 instead of the upper case C2. The upper case C2 functions as a lid that opens and closes the opening of the lower case C1. For example, the upper case C2 can be opened and closed with respect to the lower case C1 via the hinge portion C3. The hinge portion C3 extends along the first direction D1 on the far side of the eyewear case C in the second direction D2. When the eyewear ultraviolet irradiation device 1 is used, the housing 2 is placed on the lower case C1 with the upper case C2 opened. The lower case C1 is, for example, box-shaped having a bottom portion C4 on which the eyewear E is placed and side portions C5 extending upward from the bottom portion C4. In the example of FIG. 6, the bottom portion C4 corresponds to the mounting portion S on which the eyewear E is mounted.

As an example, the side portion C5 has an edge C8 and a stepped portion C11. The edge C8 is positioned at the upper end of the side portion C5 on the near side in the second direction D2 and extends in the first direction D1. The edge C8 includes a pair of side surfaces C9 facing each other in the second direction D2 and a top surface C10 connecting the pair of side surfaces C9 to each other. The stepped portion C11 protrudes from the edge C8 to the back side on the lower side of the edge C8. The step portion C11 extends along the first direction D1. The upper case C2 has, for example, the same box shape as the lower case C1, and has an opening directed downward, a bottom portion C6, and side portions C7.

The configuration of the exemplary eyewear case C has been described above. However, the configuration of the eyewear case is not limited to the examples described above. Furthermore, the cover part 3 according to this embodiment can cover the eyewear E accommodated in various eyewear cases other than the eyewear case C. As shown in FIG.

The housing 2 has a positioning portion for positioning with respect to the eyewear case C. As shown in FIG. In the present disclosure, the “positioning portion” indicates a portion that determines the position of the housing with respect to the eyewear case. The “positioning portion” may be, for example, a fitting portion of the housing that fits into the eyewear case, or a contact portion that determines the position of the housing with respect to the eyewear case while in contact with the eyewear case. Further, the "positioning section" may position the housing so that the cover section seals the lower case on which the eyewear is placed. In this embodiment, the positioning portion is the recess 6 . As an example, the positioning portion may include the recess 6, the edge 31 and the side surface 2F.

The concave portion 6 positions the housing 2 with respect to the eyewear case C by hooking on the edge C8. With the edge C8 inserted into the recess 6, the eyewear case C is caught by the housing 2. As shown in FIG. Further, the edge 31 abuts against the side surface C9, thereby preventing the housing 2 from falling out of the eyewear case C. As shown in FIG.

The side surface 2F is a portion for positioning the housing 2 with respect to the opened eyewear case C. As shown in FIG. The side surface 2F positions the housing 2 with respect to the eyewear E accommodated in the eyewear case C by contacting the bottom portion C6 of the upper case C2 of the opened eyewear case C. As shown in FIG. As described above, for example, the angle formed by the side surface 2F and the bottom surface 2A is smaller than 90 degrees. Therefore, when the upper case C2 is closed, a portion of the upper case C2 contacts a portion of the side surface 2F. In this embodiment, the bottom portion C6 of the upper case C2 contacts the vicinity of the long side 27 of the side surface 2F.

Next, the effects obtained from the ultraviolet irradiation device 1 for eyewear according to this embodiment will be described in detail. The housing 2 of the ultraviolet irradiation device 1 for eyewear according to this embodiment has a cover portion 3 that covers the eyewear E placed on the placement portion S. As shown in FIG. The housing 2 is separate from the placement section S on which the eyewear E is placed. The eyewear ultraviolet irradiator 1 can irradiate both the eyewear E housed in the eyewear case C and the eyewear E not housed in the eyewear case C with the ultraviolet rays L. Therefore, since the eyewear E can be covered only by covering the cover part 3 without taking the eyewear E into and out of the eyewear case C, the ultraviolet irradiation device 1 for eyewear can be used easily.

As described above, the housing 2 is separate from the mounting portion S on which the eyewear E is mounted, and the place on which the eyewear E is mounted is limited to cases such as the eyewear case C. can be used even without a case. That is, the eyewear E can be covered with the cover portion 3 regardless of where the mounting portion S is located. Therefore, it is not necessary to put the eyewear E in and out of the case, and the case itself in which the eyewear E is placed is also unnecessary. Therefore, since the eyewear E is placed on the mounting part S and the eyewear E is covered with the cover part 3, and the ultraviolet rays L can be irradiated, the eyewear E can be rapidly irradiated with the ultraviolet rays L, and the eyewear is highly usable. It can be an ultraviolet irradiator 1 for use. Furthermore, even eyewear with a shape that cannot be accommodated in a general eyewear case (such as goggle type) can be irradiated with ultraviolet rays L regardless of the type as long as it can be covered with the cover part 3. can. In this embodiment, the irradiation element 7 is provided at a position facing the lens E2 of the eyewear E placed on the placement portion S. As shown in FIG. Therefore, it is possible to effectively irradiate the ultraviolet rays L through the lens E2.

For example, in a store where the eyewear E is repeatedly put on and taken off, the eyewear ultraviolet irradiator 1 can be used quickly. For example, a visitor removes the eyewear E worn in a washroom, a measurement booth, or the like to measure the visual acuity of the naked eye, and covers the removed eyewear E with the eyewear ultraviolet irradiator 1 to wear the eyewear E. Can be sterilized. Also, if the eyewear ultraviolet irradiator 1 is installed on the display stand for the try-on eyewear, the try-on eyewear can be easily sterilized before and after the try-on. In addition, since the ultraviolet irradiator 1 for eyewear can irradiate the ultraviolet rays L while the eyewear E is covered with the cover part 3, the leakage of the ultraviolet rays L can be prevented and safety is excellent.

As described above, the eyewear E may be placed in such a direction that the front extending surface FS is inclined with respect to the placement portion S. The housing 2 may have an inclined portion 9 that is inclined with respect to the mounting portion S and along the front extension surface FS, and the irradiation element 7 may be arranged on the inclined portion 9 . In this case, since the front extending surface FS is inclined with respect to the mounting portion S, and the inclined portion 9 is also inclined with respect to the mounting portion S, the user of the ultraviolet irradiation device 1 for eyewear can By visually recognizing the direction of the inclined portion 9 and the direction of the front extension surface FS, it can be intuitively understood that the direction of the inclined portion 9 should be aligned with the direction of the front extension surface FS. In this embodiment, the orientation of the inclined portion 9 in the second direction D2 with respect to the orientation of the placed eyewear E in the second direction D2 can be intuitively grasped. Therefore, the user can cover the eyewear E with the cover part 3 so that the inclined part 9 is aligned with the front extension surface FS, so that the usability of the ultraviolet irradiation device 1 for eyewear can be further improved. can.

As described above, the housing 2 has the power supply section 4 that supplies power to the irradiation element 7 , and the power supply section 4 may be adjacent to the cover section 3 . By adopting a configuration in which the power supply section 4 and the cover section 3 are adjacent to each other, it becomes possible to shift the position of the power supply section 4 from the position of the cover section 3 when the mounting section S is viewed from above. . Therefore, the center of gravity of the housing 2 can be lowered compared to a configuration in which the power supply unit is arranged on the cover unit (a configuration in which the position of the power supply unit overlaps the position of the cover unit when viewed from above). The posture of the housing 2 can be stabilized.

As described above, at least part of the inner surface of the cover portion 3 facing the eyewear E side may be made of a reflective material that reflects the ultraviolet rays L. As shown in FIG. For example, at least one of the inner surface 3A, the inner surface 3B, the inner surface 3C, and the inner surface 3D may be made of a reflective material. In this case, since the ultraviolet light L emitted from the irradiation element 7 is reflected by the reflector, not only is the ultraviolet light L emitted directly from the irradiation element 7 to the eyewear E, but the ultraviolet light L is also applied to the eyewear E from the reflector. L can be irradiated. Therefore, the efficiency of irradiating the eyewear E with the ultraviolet rays L can be improved.

As described above, the housing 2 has the switch 5 for turning on the irradiation element 7, and the switch 5 is exposed on the surface of the housing 2 when viewed from above (opposite side of the mounting portion S). position. As an example, the switch 5 is arranged on the upper surface 2B of the housing 2 in this embodiment. In this case, when the eyewear E placed on the placing portion S is covered with the cover portion 3, the switch 5 is exposed. Therefore, since the switch 5 is arranged at a position visible to the user when the cover portion 3 covers the eyewear E, the operability of the operation of irradiating the ultraviolet rays L can be improved. In this embodiment, both the switch 5 and the notification section 51 are exposed when the housing 2 is placed on the placement section S. As shown in FIG. As a result, the user of the ultraviolet irradiation device 1 for eyewear can visually recognize the notification portion 51 and can easily operate the switch 5 .

As described above, the cover part 3 may cover the eyewear E housed in the eyewear case C, and the housing 2 may have a positioning part for positioning with respect to the eyewear case C. In this case, since the positioning of the ultraviolet irradiation device 1 for eyewear with respect to the eyewear case C is performed by the positioning section, the eyewear E accommodated in the eyewear case C is covered with the cover section 3 . The position of the ultraviolet irradiator 1 for wear is determined. Therefore, since the eyewear E can be irradiated with the ultraviolet rays L while the cover portion 3 is positioned with respect to the eyewear E, even the eyewear E housed in the eyewear case C is exposed to the ultraviolet rays L from the cover portion 3. The eyewear E can be appropriately irradiated with ultraviolet rays without leakage.

As described above, the power supply unit 4 may have the notification unit 51 that notifies whether the irradiation element 7 is irradiating the ultraviolet rays L or not. The notification unit 51 notifies that the irradiation element 7 is irradiating the ultraviolet rays L, so that the user of the ultraviolet irradiation device 1 for eyewear can understand that the irradiation element 7 is lit inside the cover part 3. can. The notification unit 51 can prevent the user from erroneously lifting the ultraviolet irradiator 1 for eyewear while the ultraviolet ray L is being emitted. Furthermore, the notification unit 51 informs the user of the irradiation state of the irradiation element 7 (whether or not the ultraviolet rays L are being irradiated), which cannot be directly grasped when the cover unit 3 covers the eyewear E, and whether or not the battery has run out. , and whether or not there is a problem that the irradiation element 7 does not irradiate the ultraviolet rays L can be grasped.

The embodiment of the ultraviolet irradiation device for eyewear according to the present disclosure has been described above. However, the present disclosure is not limited to the embodiments described above, and may be modified or applied to other things within the scope of not changing the gist described in each claim. That is, the configuration, function, shape, size, number, material, and layout of each part of the ultraviolet irradiator for eyewear can be changed as appropriate without departing from the scope of the above.

FIG. 7 is a partial cross-sectional view showing an ultraviolet irradiator 1A for eyewear according to a modification. Various modifications of the ultraviolet irradiator for eyewear will be described below. A part of the configuration of the ultraviolet irradiator for eyewear according to each modification described later is the same as the configuration of a part of the ultraviolet irradiator 1 for eyewear described above. In the following description, the same reference numerals are assigned to the same description as the configuration of the ultraviolet irradiator 1 for eyewear, and the description will be omitted as appropriate. An eyewear ultraviolet irradiation device 1A according to a modification includes a cushion portion 10A fixed to a rim 31 and a cushion portion 10B fixed to a lower surface 4A. Below, when there is no need to distinguish between the cushion portions 10A and 10B, the cushion portions 10A and 10B may be collectively referred to as the cushion portion 10 .

The cushion portion 10A extends along the edge 31. As shown in FIG. When viewed from below, the cushion portion 10A has an annular shape. For example, the cushion portion 10A is fixed to the opening of the cover portion 3. As shown in FIG. The cushion portion 10A is fixed, for example, to the lower surface of the edge 31 and part of the inner surfaces 3B, 3C, and 3D. Thus, the cushion part 10A may be fixed to a part of the inner surfaces 3B, 3C, 3D. In this case, a portion of the cushion portion 10A faces the eyewear E covered with the cover portion 3. As shown in FIG. As an example, the cushion part 10B extends along the lower surface 4A. For example, when viewed along the third direction D3, the outer shape of the cushion portion 10B and the outer shape of the lower surface 4A overlap each other.

The cushion part 10 is made of, for example, a flexible material that is more flexible than the housing 2 . The cushion part 10 is made of sponge or rubber, for example. As an example, the cushion part 10 is made of urethane sponge. The cushion part 10 is fixed by, for example, an adhesive.

As described above, the ultraviolet irradiation device 1A for eyewear according to the modified example includes the cushion portion 10A fixed to the edge 31 . Further, the cushion portion 10A may be fixed to the edge 31 so as to face the eyewear E covered with the cover portion 3. As shown in FIG. In the configuration including the cushion portion 10A fixed to the edge 31, when the eyewear E placed on the mounting portion S is covered with the cover portion 3, the eyewear E is damaged by the contact between the edge 31 and the eyewear E. damage can be prevented.

Further, the cushion portion 10 may be fixed to the lower surface 2A of the housing 2 (for example, the entire lower surface 2A). In this case, when the eyewear E placed on the mounting portion S is covered with the cover portion 3, the cushion portion 10 is sandwiched between the lower surface 2A and the mounting portion S, so that the mounting portion S is completely covered. The cover part 3 can be stabilized even when it is not flat. That is, as schematically shown in FIG. 7, the housing 2 is stabilized by the flexible deformation of the cushion portion 10 placed on the mounting portion S even for the mounting portion S having unevenness. can be placed

FIG. 8 is a partial cross-sectional view showing an ultraviolet irradiator 1B for eyewear according to a modification different from FIG. A housing 102 of the ultraviolet irradiation device for eyewear 1B has a rectangular parallelepiped shape. The housing 102 has an upper surface 102B facing away from the lower surface 2A. The upper surface 102B extends, for example, along a plane orthogonal to the third direction D3. The housing 102 has a side surface 102D extending along a plane perpendicular to the second direction D2 and a side surface 102F facing away from the side surface 102D. The side surface 102D is positioned on the front side of the housing 102 . The side surface 102F is positioned on the back side of the housing 102 . The housing 102 has a pair of side surfaces 102E facing each other in the first direction D1. Each side 102E extends, for example, along a plane orthogonal to the first direction D1. The lower surface 2A and the upper surface 102B are connected to each other via side surfaces 102D, 102E, and 102F.

The housing 102 has a cover portion 103 and a power supply portion 104 . In plan view, the power supply unit 104 overlaps the cover unit 103 . The power supply unit 104 and the cover unit 103 are adjacent to each other along the third direction D3. The power supply unit 104 is positioned above the cover unit 103 .

In the eyewear ultraviolet irradiation device 1B, the switch 5 and the notification unit 51 are located, for example, on the upper surface 102B. As an example, the switch 5 and the notification unit 51 protrude from the upper surface 102B.

The cover portion 103 has an inner surface 103C facing forward. 103 C of inner surfaces are located in the back side of the side surface 102F. The inner surface 103C extends along the side surface 102F. For example, the inner surface 103C extends downward from the long side 33 toward the lower surface 31A. As an example, the inner surface 103C is orthogonal to the mounting portion S.

Since the configuration in which the position of the power supply unit 104 and the position of the cover unit 103 overlap when viewed from above is compact when viewed from above, the ultraviolet irradiator for eyewear can be used even in a limited range of the mounting unit S. 1B can be used.

FIG. 9 is a partial cross-sectional view showing an ultraviolet irradiation device 1C for eyewear according to a modification different from FIGS. 7 and 8. As shown in FIG. The housing 102 of the eyewear ultraviolet irradiation device 1</b>C has a cover portion 203 . The cover portion 203 has inner surfaces 203A, 203B, 203C, and 203D facing the eyewear side. For example, the inner surface 203A is a surface facing the mounting portion S. 203 A of inner surfaces are extended along the plane orthogonal to the 3rd direction D3 as an example. The inner surface 203B faces the back side, and the inner surface 203C faces the front side. The inner surfaces 203B and 203C extend, for example, along a plane orthogonal to the second direction D2. The inner surface 203B and the inner surface 203C face each other in the second direction D2. The pair of inner surfaces 203D face each other in the first direction D1. The inner surface 203B and the inner surface 203C are connected to each other via each inner surface 203D. The inner surfaces 203A, 203B, 203C, and 203D define an internal space of the cover portion 203 which, together with the mounting portion S, has a rectangular parallelepiped shape, for example.

The inner surface 203A has an opening 35A. For example, the inner surface 203A has a pair of openings 35A arranged along the first direction D1 corresponding to the positions of the lenses E2. An irradiation element 7A is arranged inside each opening 35A. The inner surface 203B has an opening 35B. For example, the inner surface 203B is formed with a pair of openings 35B aligned along the first direction D1 corresponding to the positions of the lenses E2. An irradiation element 7B is arranged inside each opening 35B. The irradiation elements 7A and 7B irradiate the ultraviolet rays L from a direction intersecting the front extension surface FS. 7 A of irradiation elements are provided above the lens E2 of the eyewear E mounted in the mounting part S, for example. The irradiation element 7B is provided on the front side of the lens E2 of the eyewear E placed on the placement portion S, for example. The irradiation elements 7A and 7B irradiate each lens E2 with ultraviolet rays L from two directions intersecting the front extension surface FS.

In a configuration in which the irradiation elements 7A and 7B are positioned in different directions as viewed from the lens E2, the irradiation elements 7A and 7B can irradiate the lens E2 with the ultraviolet light L from different directions.

Various modifications of the ultraviolet irradiator for eyewear have been described above. However, the ultraviolet irradiator for eyewear according to the present disclosure is not limited to the various modifications described above, and can be further modified. For example, in the above-described embodiment, the example having the concave portion 6 functioning as the positioning portion has been described. However, the shape of the positioning portion is not limited to the concave portion 6, and may be, for example, a convex portion, and can be changed as appropriate. The size and location of the positioning portion can also be changed as appropriate. Furthermore, the positioning part may be omitted. Furthermore, in the above-described embodiments, the example in which the reflector is provided on at least one of the inner surfaces of the cover portion has been described. However, the reflective material may not be provided on the inner surface of the cover portion.

Further, the eyewear ultraviolet irradiation device may include a sensor for detecting whether or not the cover portion covers the eyewear (whether or not the eyewear exists inside the cover portion). As an example, the sensor is a photoelectric sensor. In this case, the photoelectric sensor includes an emitting portion that emits light and a light receiving portion that receives the light reflected by the emitted light from the emitting portion. Detects whether eyewear exists inside.

In this way, when the sensor detects whether or not eyewear exists inside the cover, the controller controls the eyewear when the sensor detects that the eyewear exists inside the cover. It can be exposed to UV rays. Therefore, unnecessary irradiation of ultraviolet rays can be suppressed, and safety can be improved.

In the above-described embodiment, an example in which the irradiation element 7 irradiates the eyewear E with the ultraviolet rays L along with the operation of the switch 5 has been described. However, in the ultraviolet irradiation device for eyewear, the irradiation element may automatically irradiate the eyewear with ultraviolet rays when the cover part covers the eyewear. For example, ultraviolet rays may be emitted automatically when the sensor described above detects eyewear inside the cover. Further, the irradiation of ultraviolet rays may be automatically stopped when the housing is separated from the placing portion, or the irradiation of ultraviolet rays may be automatically stopped after a certain period of time has elapsed from the start of the irradiation of ultraviolet rays.

In the above-described embodiment, an example in which the switch 5 is provided on the upper surface 2B of the housing 2 has been described. However, the position of the switch of the ultraviolet irradiation device for eyewear may be, for example, the top surface 2C or the side surfaces 2D, 2E, 2F, etc., and can be changed as appropriate. Furthermore, when the ultraviolet irradiation is performed automatically as described above, it is possible to omit the switch. Further, in the above-described embodiment, an example in which the ultraviolet irradiation device 1 for eyewear is mounted on the mounting portion S extending substantially horizontally has been described. However, the direction in which the mounting portion extends may be a direction oblique to the horizontal direction or may be a vertical direction, and is not particularly limited. The direction of the ultraviolet irradiation device for eyewear with respect to the placement section is also not particularly limited. As described above, the ultraviolet irradiation device for eyewear according to the present disclosure can be used for various mounting portions.
