Description

Technical Field

[0001] This disclosure pertains to umbrellas. Background Technology

[0002] Patent document 1 discloses an umbrella sheet and an umbrella using the sheet as a lining, the sheet being made of paper or nonwoven fabric that has the function of blocking both harmful ultraviolet rays and infrared rays.

[0003] This umbrella uses a sheet material as its lining, obtained by coating or impregnating a substrate made of paper or nonwoven fabric with an adhesive mixture. This adhesive mixture is made by dispersing zinc oxide particles, which have the effect of absorbing ultraviolet rays and reflecting infrared rays, in an adhesive such as a vinyl acetate-maleic acid copolymer compound. Especially when using washi paper as the material, it not only blocks ultraviolet rays to protect the skin but also reflects infrared rays, making it easier to withstand hot summer weather, and it is also highly fashionable.

[0019] (Insights, etc., that form the basis of this disclosure)

[0020] When the inventor conceived of this disclosure, there existed a technique for forming an umbrella using sheets that block ultraviolet and infrared rays. Thus, the user of the umbrella could block ultraviolet rays to protect their skin and reflect infrared rays to suppress the rise in body temperature.

[0021] However, the inventors discovered the following problem: when the user uses the umbrella, the infrared rays do not reach the user, and the beauty effect of infrared rays on the user's skin cannot be obtained. The subject of this disclosure was conceived in order to solve this problem.

[0022] Therefore, this disclosure provides an umbrella that can enhance the cosmetic effect on the skin.

[0023] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. However, sometimes unnecessary detailed descriptions are omitted. For example, detailed descriptions of already known matters or repeated descriptions of substantially the same structures are sometimes omitted. This is to avoid unnecessarily lengthy descriptions and to facilitate understanding by those skilled in the art.

[0024] Furthermore, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand this disclosure and are not intended to limit the subject matter of the claims.

[0025] (Implementation Method 1)

[0026] The following uses Figures 1-3 Implementation method 1 is described below.

[0027] In the following embodiments, unless otherwise specified, the vertical direction of the umbrella is defined as the direction in which the length of the central rod is aligned with the vertical direction, the clamp is on top, and the handle is on the bottom. Furthermore, in the following embodiments, in the umbrella 1 used by the user in the open state, the area located on the user's side and surrounded by the umbrella fabric 50 is defined as the inner side of the umbrella 1, and the area on the opposite side of the user's side, separated by the umbrella fabric 50, is defined as the outer side of the umbrella 1.

[0028] [1-1. Structure]

[0029] [1-1-1. The structure of an umbrella]

[0030] (Implementation Method)

[0031] Figure 1 This is a perspective view of umbrella 1 according to an embodiment of this disclosure. Figure 1 For ease of explanation, the wavelength transmission fabric is represented by shaded points (52).

[0032] like Figure 1 As shown, the umbrella 1 of this embodiment includes an umbrella body 10 and an umbrella fabric 50 supported on the umbrella body 10. The umbrella fabric 50 is equivalent to the "sheet" of this disclosure.

[0033] The umbrella body 10 includes a central rod 20, a fixed umbrella nest 22 disposed at the top end of the central rod 20, multiple main ribs 30 connected to the fixed umbrella nest 22, and an umbrella fabric 50 covering the multiple main ribs 30. The central rod 20 is equivalent to the "axis" of this disclosure, and the main ribs 30 are equivalent to the "ribs" of this disclosure.

[0034] Figure 2 This is a side view of the umbrella body 10.

[0035] like Figure 1 , Figure 2 As shown, the central rod 20 is a long, rod-shaped component extending vertically. A fixing umbrella nest 22 is provided at the upper end of the central rod 20. A clamp 24 is provided at the upper end of the central rod 20 via the fixing umbrella nest 22. The clamp 24 is formed into a rod shape and is installed so that its length extends along the length direction of the central rod 20. A handle 26 for the user to hold is installed at the lower end of the central rod 20.

[0036] like Figure 2 As shown, a movable umbrella nest 28 is provided on the portion of the center rod 20 located between the fixed umbrella nest 22 and the handle 26, in a manner that allows it to slide along the length of the center rod 20. The user can open and close the umbrella 1 by sliding the movable umbrella nest 28 in the up-down direction.

[0037] The center rod 20 is provided with an upper latch 32 and a lower latch 34. The upper latch 32 and lower latch 34 are protruding pieces that are stressed by a spring member or the like, protruding outwards from a through hole on the side of the center rod 20. The upper latch 32 is located below and near the fixed umbrella nest 22. The lower latch 34 is located above and near the handle 26.

[0038] When the movable umbrella nest 28 is pressed down to insert into the center rod 20 and slides to a position above the upper latch 32, its downward movement is restricted by the upper latch 32 protruding from the center rod 20. Thus, the umbrella 1 is kept in the open state.

[0039] Similarly, when the movable umbrella nest 28 is inserted into the center rod 20 and slid to a position lower than the lower latch 34, its upward movement is restricted by the lower latch 34 protruding from the center rod 20. Thus, the umbrella 1 is kept in the closed state.

[0040] Multiple main ribs 30 are installed in the fixed umbrella nest 22 in a radially extending manner. Each main rib 30 is installed in the fixed umbrella nest 22 in a state that allows it to swing vertically with its end located on the side of the fixed umbrella nest 22 as a base point.

[0041] The movable umbrella nest 28 is equipped with the same number of branch ribs 40 as the main ribs 30, extending radially. Each branch rib 40 is mounted to the movable umbrella nest 28 in a manner that allows it to swing vertically with its end located on one side of the movable umbrella nest 28 as a base. A joint 36 is provided at the center of each main rib 30. In each branch rib 40, the end located on the side opposite to the end connected to the movable umbrella nest 28 is rotatably mounted to the joint 36 formed on the corresponding main rib 30.

[0042] Thus, in the umbrella body 10, the rib 40 and the movable umbrella nest 28 slide in a linkage in the vertical direction and swing in the vertical direction, and the main rib 30 and the rib 40 swing in a linkage in the vertical direction.

[0043] When the user slides the movable umbrella nest 28 upward, the support rib 40 rotates downward. By rotating the support rib 40 downward, the main rib 30 rotates upward, thereby opening the umbrella 1.

[0044] When the user slides the movable umbrella nest 28 downwards, the support rib 40 rotates upwards. By rotating the support rib 40 upwards, the main rib 30 rotates downwards, thereby closing the umbrella 1.

[0045] like Figure 1 As shown, the umbrella 1 is provided with a sheet-like umbrella fabric 50 covering multiple main ribs 30. A through hole 51 is formed in the center of the umbrella fabric 50, extending along the thickness direction of the umbrella fabric. A clamp 24 passes through this through hole. In this state, the umbrella fabric 50 is glued or sewn to the fixing umbrella nest 22, the main ribs 30, and the umbrella beads 38 provided at the top of the main ribs 30 on the side opposite to the side where the fixing umbrella nest 22 is located. Thus, in the umbrella 1, the umbrella fabric 50 is installed on the main ribs 30 in a state of covering multiple main ribs 30.

[0046] Umbrella 1 can be used as an umbrella for rainy days, a parasol for sunny days, or a dual-purpose umbrella that can be used in both rainy and sunny days.

[0047] [1-1-2. Structure of Umbrella Fabric]

[0048] In the umbrella 1 of this embodiment, an umbrella fabric 50 is used that can improve the skin beauty effect of the user when using the umbrella 1.

[0049] The umbrella fabric 50 is formed by combining a wavelength-transmitting fabric 52 and a light-blocking fabric 54. The wavelength-transmitting fabric 52 corresponds to the "wavelength-transmitting part" of this disclosure, and the light-blocking fabric 54 corresponds to the "light-blocking part" of this disclosure.

[0050] Wavelength-transmitting fabric 52 is a sheet-like component made of a material that transmits infrared light but reflects or absorbs ultraviolet light over at least one side of a substantially integral area.

[0051] In this embodiment, a wavelength-transmitting fabric 52 is installed between two adjacent main ribs 30. The wavelength-transmitting fabric 52 extends from the fixed umbrella nest 22 to a position adjacent to the umbrella bead 38 along the length direction of each main rib 30 and is fixed to each main rib 30. That is, the wavelength-transmitting fabric 52 is disposed from the upper end to the lower end of the two adjacent main ribs 30.

[0052] With umbrella 1 in the open state, wavelength transmission fabric 52 is stretched circumferentially between two adjacent main ribs 30 of umbrella 1.

[0053] The light-blocking fabric 54 is a sheet-like component that uses a material that reflects or blocks sunlight over at least one side, approximately the entire area. The light-blocking fabric 54 can be made of any material that reflects or blocks light, such as a light-reflecting sheet or a light-blocking sheet. Alternatively, for example, in the case of umbrella 1, a sheet-like material with heat-blocking properties can be used instead of the light-blocking fabric 54.

[0054] The light-blocking fabric 54 in this embodiment uses a material with a transmittance of approximately 0% for light less than 400 nm.

[0055] In this embodiment, the light-blocking fabric 54 is made of a breathable fabric or similar material. This allows air and water vapor to pass through the light-blocking fabric 54 from the inside to the outside of the umbrella. Therefore, temperature rise on the inside of the umbrella 1 can be suppressed, improving user comfort.

[0056] The light-blocking fabric 54 forms a substantially integral part of the umbrella fabric 50 installed in the umbrella body 10, except for the portion where the wavelength-transmitting fabric 52 is provided. The light-blocking fabric 54 extends along the length of each main rib 30 from the fixed umbrella nest 22 to a position adjacent to the umbrella bead 38, and is fixed to each main rib 30. That is, the wavelength-transmitting fabric 52 is provided between two adjacent main ribs 30 from the upper end to the lower end of the rib. When the umbrella 1 is in the open state, the light-blocking fabric 54 extends circumferentially over the entire area of ​​the umbrella 1 except for the portion where the wavelength-transmitting fabric 52 is provided.

[0057] In addition, the light-blocking fabric 54 and the wavelength-transmitting fabric 52 can also be connected to each other by various joining methods such as bonding, welding, or sewing.

[0058] [1-1-3. Structure of Wavelength Transmission Fabric]

[0059] Figure 3 This is a cross-sectional view of wavelength transmission fabric 52.

[0060] like Figure 3 As shown, a wavelength-transmitting fabric 52 is formed by layering a wavelength-transmitting material 64 over a substantially entire area of ​​one side of a sheet-like fabric body 62.

[0061] In this embodiment, the fabric body 62 is a substrate on which the wavelength transmission material 64 is disposed. The fabric body 62 is a flexible transparent member obtained by forming a sheet of resin materials such as polyethylene (PE) and ethylene-vinyl acetate (EVA). Therefore, in the wavelength transmission fabric 52, it is possible to suppress the absorption of light by the fabric body 62 when light passes through it.

[0062] In this embodiment, at least one surface treatment, such as a matte finish, can be applied to at least one of the textures and feel of the blackout fabric 54. Such a surface treatment is preferably applied to the outer surface of the fabric body 62 located on the umbrella 1.

[0063] Therefore, in umbrella 1, it is possible to suppress a significant difference in appearance between the wavelength transmission fabric 52 and the light-blocking fabric 54. Thus, in umbrella 1, the aesthetics of the umbrella fabric 50 can be improved.

[0064] In this embodiment, a wavelength-transmitting material 64 is provided on the inner surface of the fabric body 62 located on the umbrella 1, covering approximately the entire surface. The wavelength-transmitting material 64 is a material that transmits infrared light but blocks or absorbs ultraviolet light. Specifically, the wavelength-transmitting material 64 is a material that transmits light with wavelengths of 400 nm or higher but blocks or absorbs light with wavelengths less than 400 nm. The wavelength-transmitting material 64 in this embodiment uses a material with a transmittance of approximately 0% for light with wavelengths less than 400 nm.

[0065] Wavelength-transmitting material 64 includes infrared-transmitting ink. Infrared-transmitting ink is an ink that transmits near-infrared light in the wavelength range above 400 nm but suppresses the transmission of visible light and ultraviolet light. As an example, infrared-transmitting ink is an ink that can transmit more than 70% of near-infrared light in the wavelength range above 400 nm.

[0066] Infrared transmission inks may include, for example, coloring materials and resin components. The coloring materials may include dyes, and at least one of coloring pigments such as inorganic and organic pigments. Preferably, coloring pigments are included as the coloring materials. Coloring pigments are not particularly limited; examples include inorganic and organic pigments, which may be used alone or together. Coloring pigments may also include at least one selected from the group consisting of perylene-based pigments and phthalocyanine-based pigments.

[0067] As a resin component, there are no particular limitations. For example, one or more of various resins such as acrylic resins, vinyl chloride resins, butyraldehyde resins, polyester resins, polyurethane resins, cellulose resins, and epoxy resins can be used.

[0068] Infrared transmission inks can also contain various additives as needed. These additives can include at least one of the following: surfactants, surface conditioners, defoamers, leveling agents, curing accelerators, dispersants, light stabilizers, flow conditioners, polymerization inhibitors, coupling agents, curing agents, and antioxidant polymerizers.

[0069] Wavelength transmission material 64 is formed on the outer surface of the fabric body 62 in the form of a thin film through various methods such as printing, coating or vapor deposition.

[0070] Therefore, in umbrella 1, the increased thickness of the wavelength-transmitting fabric 52 suppresses the reduction in flexibility and facilitates the installation of the wavelength-transmitting material 64. Consequently, in umbrella 1, it is possible to suppress situations where the opening and closing operation is hindered by the umbrella fabric 50.

[0071] Wavelength-transmitting material 64 is disposed on the inner surface of the fabric body 62 located on the umbrella 1. Therefore, in the umbrella 1, the exposure of the wavelength-transmitting material 64 to wind and rain can be suppressed. Thus, in the umbrella 1, the degradation of the wavelength-transmitting material 64 can be suppressed.

[0072] In addition, wavelength transmission material 64 can also be coated on both sides of the fabric body 62.

[0073] In this embodiment, a cover layer 66 is provided on the wavelength-transmitting fabric 52. The cover layer 66 is a thin film that covers the wavelength-transmitting material 64 from the side opposite to the side where the fabric body 62 is located, with the wavelength-transmitting material 64 in between. The cover layer 66 uses various materials capable of covering and protecting the wavelength-transmitting material 64, such as varnish ink.

[0074] In addition, similar to the main fabric 62, the covering layer 66 may also be subjected to a surface treatment that gives it at least one of the textures and feel similar to the surface of the blackout fabric 54, such as a matte finish.

[0075] Here, the inventors have obtained the following insights through experiments: when the area of ​​the outer side of the wavelength-transmitting fabric 52 is less than 30% of the area of ​​the outer side of the umbrella fabric 50, it is possible to provide a cosmetic effect to the skin of the user using the umbrella 1, and to suppress the temperature rise on the inner side of the umbrella 1 without compromising the user's comfort. Therefore, in this embodiment, the wavelength-transmitting fabric 52 is provided such that it constitutes less than 30% of the area of ​​the outer side of the umbrella fabric 50.

[0076] [1-2. Actions]

[0077] Next, the operation of this embodiment will be explained.

[0078] When the user opens the umbrella 1, light with wavelengths above 400nm incident on the wavelength-transmitting fabric 52 is transmitted, while light with wavelengths below 400nm is blocked. Thus, the umbrella 1 can suppress the effects of light with wavelengths below 400nm that could strike the user's skin and eyes and cause photoaging.

[0079] Here, light with wavelengths above 400nm is used to kill acne bacteria and is also used in acne treatment. In addition, it is believed to be effective in the recovery of bruises.

[0080] Light with wavelengths above 500nm, especially near-infrared light with wavelengths above 700nm, can penetrate deep into the skin and act on melanin, and is believed to be effective against spots and freckles.

[0081] In this way, Umbrella 1 can block ultraviolet light and allow more transmitted light containing wavelengths above 400nm to effectively reach the user's skin. Therefore, Umbrella 1 can provide cosmetic effects to the user's skin, such as improving fine lines, acne, redness, moisturizing, minimizing pores, anti-inflammatory effects, reducing sebum, improving wrinkles, improving blemishes, promoting metabolism, and increasing collagen production.

[0082] In addition, infrared rays also have the effect of warming the body. Therefore, by using umbrella 1, the user can actively irradiate the body with infrared rays without blocking them, and can expect the effect of properly warming the body.

[0083] In contrast, for light incident on the light-blocking fabric 54, light smaller than 400 nm is blocked, and the transmittance of light smaller than 750 nm is approximately 50% or less. Therefore, in umbrella 1, it is possible to suppress the effects of light smaller than 400 nm incident on the user's skin and eyes, such as photoaging, and to suppress the transmission of light with wavelengths greater than 400 nm, which would cause a temperature rise on the inner side of umbrella 1. Thus, in umbrella 1, user comfort can be improved.

[0084] As described above, in the umbrella fabric 50 installed on the umbrella 1, the wavelength transmission fabric 52 extends from the upper end to the lower end and is disposed in a portion of the circumferential direction of the umbrella 1 in the open state.

[0085] When umbrella 1 is open, the user can also manipulate umbrella 1 to position the wavelength-transmitting fabric 52 between the main component of the light incident on umbrella 1 and the user's face. In this case, the user can block ultraviolet light and more effectively allow more transmitted light containing wavelengths above 400nm to reach the user's skin.

[0086] In addition, users can also position the wavelength-transmitting fabric 52 opposite to the part of their face that they want to be irradiated with infrared light.

[0087] [1-3. Effects, etc.]

[0088] As described above, in this embodiment, the umbrella 1 includes an umbrella body 10 and an umbrella fabric 50 supported on the umbrella body 10. The umbrella fabric 50 uses a wavelength transmission material 64 that can transmit light with wavelengths of 400 nm or higher.

[0089] Therefore, umbrella 1 can block ultraviolet light and allow more transmitted light containing wavelengths above 400nm to effectively reach the user's skin. Thus, umbrella 1 can provide a cosmetic effect on the skin of the user.

[0090] As in this embodiment, the umbrella fabric 50 may also include: a wavelength-transmitting fabric 52, which uses a wavelength-transmitting material 64, capable of transmitting light with wavelengths above 400 nm; and a light-blocking fabric 54, which uses a light-blocking material capable of blocking light incident on the umbrella fabric 50.

[0091] Therefore, in umbrella 1, a greater amount of transmitted light containing wavelengths above 400nm can effectively reach the user's skin, and air and water vapor can pass through from the inside to the outside of the umbrella. Thus, umbrella 1 can provide a cosmetic effect to the user's skin and can suppress temperature rise on the inside of umbrella 1, thereby improving the user's comfort.

[0092] As in this embodiment, the wavelength-transmitting fabric 52 may also include: a fabric body 62 formed of a material capable of transmitting light; and a wavelength-transmitting material 64 formed of the wavelength-transmitting material 64 disposed on the fabric body 62.

[0093] Therefore, umbrella 1 can block ultraviolet light and allow more transmitted light containing wavelengths above 400nm to effectively reach the user's skin. Thus, umbrella 1 can provide a cosmetic effect on the skin of the user.

[0094] As in this embodiment, the wavelength-transmitting fabric 52 may be formed of a resin material, and the light-blocking fabric 54 may be formed of cloth.

[0095] Therefore, in umbrella 1, a greater amount of transmitted light containing wavelengths above 400nm can effectively reach the user's skin, and air and water vapor can pass through from the inside to the outside of the umbrella. Thus, umbrella 1 can provide a cosmetic effect to the user's skin and can suppress temperature rise on the inside of umbrella 1, thereby improving the user's comfort.

[0096] As in this embodiment, the area of ​​the wavelength transmission fabric 52 may be less than 30% of the area of ​​the umbrella fabric 50.

[0097] Therefore, umbrella 1 can provide a cosmetic effect to the skin of the user and can suppress the rise in temperature on the inside of umbrella 1, thereby improving the user's comfort.

[0098] (Other implementation methods)

[0099] As described above, Embodiment 1 has been presented as an example of the technology disclosed in this application. However, the technology disclosed herein is not limited to this and can be applied to embodiments with modifications, substitutions, additions, omissions, etc. Furthermore, new embodiments can be created by combining the constituent elements described in Embodiment 1 above.

[0100] Other implementation methods are illustrated below.

[0101] In the above embodiment, the wavelength transmission fabric 52 extends from the upper end to the lower end of the umbrella 1 and is disposed in a portion of the circumferential direction of the umbrella 1 in the open state.

[0102] However, this is not the only limitation. As long as the umbrella fabric 50 is formed by combining the wavelength transmission fabric 52 and the light-blocking fabric 54, the wavelength transmission fabric 52 and the light-blocking fabric 54 in the umbrella 1 can be arbitrarily configured.

[0103] Figure 4 This is a perspective view of the umbrella, a modified example disclosed herein. Figure 4 For ease of explanation, the wavelength transmission fabric is represented by shaded points (52).

[0104] For example, such as Figure 4 As shown, it can also be configured such that wavelength-transmitting fabric 52 forms the upper side of umbrella fabric 50, and light-blocking fabric 54 forms the lower side of umbrella fabric 50.

[0105] exist Figure 4 In this structure, the wavelength-transmitting fabric 52 has a through hole 51 through which the clamp 24 passes, forming the upper side of the umbrella fabric 50 when installed on the umbrella body 10. The wavelength-transmitting fabric 52 is installed on the main rib 30 in a crown-like shape when the umbrella 1 is in the open state. In this case, the through hole 51 is located at the apex of the crown-shaped wavelength-transmitting fabric 52. The wavelength-transmitting fabric 52 is fixed to the umbrella body 10 by attaching it to the midpoint of its length from the fixed umbrella nest 22 to the main rib 30.

[0106] The upper end of the light-blocking fabric 54 is installed at the midpoint of the main rib 30 along its length, and the lower end is installed near the umbrella bead 38. Therefore, when the light-blocking fabric 54 is installed on the umbrella body 10, it forms the lower side of the umbrella fabric 50. The light-blocking fabric 54 is configured such that, when viewed from above the umbrella 1 in the open state, it surrounds the wavelength-transmitting fabric 52 in the entire circumferential direction.

[0107] In this modified example, the upper end of the light-blocking fabric 54 is configured to overlap with and be located below the lower end of the wavelength-transmitting fabric 52. Furthermore, the light-blocking fabric 54 and the wavelength-transmitting fabric 52 are configured not to be connected to each other except at the location where they are fixed to the main frame 30. Therefore, the umbrella 1 can be easily formed, and by providing a gap between the wavelength-transmitting fabric 52 and the light-blocking fabric 54, air and water vapor can pass through this gap from the inside to the outside of the umbrella. Thus, in the umbrella 1, temperature rise on the inside of the umbrella 1 can be suppressed, thereby improving user comfort.

[0108] Furthermore, not limited to this, the upper end of the light-blocking fabric 54 and the lower end of the wavelength-transmitting fabric 52 can also be connected at least partially to each other by various joining methods such as bonding, welding, or sewing.

[0109] In this modified example, when the umbrella 1 is in the open state, the wavelength transmission fabric 52 is disposed at the top. In addition, when viewed from above in the open state, the wavelength transmission fabric 52 is disposed at the center and has a predetermined width dimension in the direction in which the main rib 30 extends from the center rod 20, covering approximately the entire circumferential range of the umbrella 1.

[0110] Therefore, when the user uses the umbrella 1 in the open state, a wavelength-transmitting fabric 52 can be arranged at the upper part of the umbrella 1, where the main component of sunlight is easily incident, covering the entire circumference of the umbrella 1. Thus, when the user opens the umbrella 1, it is easy to arrange the wavelength-transmitting fabric 52 between the main component of sunlight and the user's face, and a cosmetic effect for the user's skin can be easily obtained.

[0111] In the above embodiment, the umbrella fabric 50 is formed by combining a wavelength-transmitting fabric 52 and a light-blocking fabric 54. However, it is not limited to this; the umbrella fabric 50 may also be formed entirely of a resin material and formed by providing a wavelength-transmitting material 64 in an area of ​​less than 30% of the outer surface of the umbrella fabric 50. In this case, the wavelength-transmitting material 64 can be provided at any location on the umbrella fabric 50. Alternatively, in this case, a material that reflects or blocks light may be provided on areas of the umbrella fabric 50 other than those where the wavelength-transmitting material 64 is provided. This material may be a light-blocking ink printed on the umbrella fabric 50.

[0112] Alternatively, for example, a reflective material capable of reflecting light with wavelengths above 400nm can be provided on the inside of the light-blocking fabric 54.

[0113] The above embodiments are used to illustrate the technology in this disclosure, and therefore various changes, substitutions, additions, omissions, etc., can be made within the scope of the claims or their equivalents.

[0115] Based on the description of the above embodiments, the following technology is disclosed.
