[Figure 3] This diagram illustrates the direction of light emitted from the self-defense umbrella 1 and the direction in which the self-defense umbrella 1 should be pointed. [Figure 4] This is a flowchart explaining how to use the self-defense umbrella 1 (S10). [Figure 5] This diagram illustrates the overall configuration of a modified self-defense umbrella 3. [Modes for carrying out the invention]

[0013] First, let me explain the background to the present invention. There are umbrellas with a light-emitting function that improves visibility to those around the person carrying the umbrella at night or on dark roads, thereby preventing traffic accidents and collisions. However, these umbrellas are intended for crime prevention purposes and are not intended to be useful for self-defense when attacked by an assailant. Therefore, in view of the above problems, the present invention aims to realize a self-defense umbrella for the purpose of protecting oneself from attackers.

[0014] Embodiments of the present invention will be described below with reference to the drawings. However, the scope of the present invention is not limited to the illustrated examples. Figure 1 is an example of a self-defense umbrella 1. Note that in Figure 1, half of the self-defense umbrella 1 is shown in perspective to illustrate its structure. As illustrated in Figure 1, the self-defense umbrella 1 has a central shaft 10, a ferrule 12, ribs 14, reinforcing ribs 16, a sheet section 18, a light-emitting device 20, and a power supply 22. The central shaft 10 is a support column for the self-defense umbrella 1. A handle 100, which is the part the user holds the self-defense umbrella 1, is formed at one end, and a ferrule 12 is provided at the other end. The central shaft 10 is a lightweight, impact-resistant metal rod-shaped component with a diameter of 10 mm or more. Specifically, the central shaft 10 is made of iron, aluminum, or a material with equivalent or greater hardness. In other words, the central shaft 10 has high resistance to attacks.

[0015] The tip 12 is a hollow component attached to the end of the central shaft 10, with its tip formed of a translucent material. Specifically, the tip 12 is attached to the other end of the shaft where the handle 100 is formed. As illustrated in Figure 2, the tip 12 is composed of a translucent material and an opaque material. The ratio of translucent material to opaque material in the tip 12 should be such that the direction of light is determined when light from a light source is emitted from the translucent material. In this example, about one-third of the tip 12 is composed of a translucent material. This prevents excessive diffusion of light and allows for a defined direction of illumination, making it possible to emit a powerful beam of light towards an attacker. Furthermore, because the direction of light illumination is determined, the user can defend themselves without being exposed to a powerful beam of light. Furthermore, the inside of the tip 12 is not divided into a translucent member and an opaque member, and the light irradiated from the light source 200 located on the opaque member side inside the tip 12 travels from the opaque member side to the translucent member side. The translucent material is a translucent resin or glass, such as polycarbonate, acrylic, polypropylene, polyethylene terephthalate, or silicone. The non-translucent material is such as ABS resin, polypropylene, polyamide, or metal.

[0016] The main ribs 14 are the framework that supports the sheet section 18 when the self-defense umbrella 1 is opened. The main ribs 14 radiate outwards from the tip 12. The main ribs 14 are made of lightweight, impact-resistant, and flexible fiberglass, providing high resistance to attacks. The receiving bone 16 cooperates with the parent bone 14 to support the protective umbrella 1. Specifically, the receiving bone 16 supports the opened parent bone 14 and maintains the strength of the protective umbrella 1. The receiving bone 16, like the parent bone 14, is made of fiberglass that is lightweight, impact-resistant, and flexible, and has high attack resistance.

[0017] The sheet part 18 is a sheet-like member with anti-cutting properties attached to the parent bone 14 that radiates from the stone protrusion 12. Specifically, the sheet part 18 is a fabric woven from anti-cutting yarns. The anti-cutting yarns are yarns with excellent anti-cutting ability and are high molecular polyethylene yarns, aramid fiber yarns, polyarylate yarns, metal yarns, or mixed yarns containing at least one of them. In this example, the anti-cutting yarns use CYGUS / Sigus (Composite Yarn Guarding Slash) manufactured by TASKMATE Co., Ltd. Also, the sheet part 18 preferably has permeability. Thereby, when the protective umbrella 1 is opened and the user is inside the protective umbrella 1, the user can surely irradiate the light while seeing the other party through the sheet 18. Since the light irradiated from the LED light 200 has straightness, the user in the direction opposite to the light irradiation direction is not dazzled.

[0018] The lighting device 20 has a light source 200 and a switch 202. The light source is an LED light that allows light to penetrate into the stone protrusion 12 and is arranged inside the stone protrusion 12. Hereinafter, the light source 200 will be described as the LED light 200. The LED light 200 and the switch 202 are electrically connected to the power source 22 via a lead wire passing through the middle rod 10. The amount of light irradiated by the LED light 200 is an amount of light that can dazzle a person's eyes with the directed light, specifically, 1000 lumens or more.

[0019] Switch 202 controls the illumination of the LED light 200. Specifically, when the user presses switch 202, switch 202 controls the illumination, flashing illumination, and deactivation of the LED light 200. Specifically, switch 202 is activated when the self-defense umbrella 1 is open. This ensures that even if switch 202 is accidentally pressed while the self-defense umbrella 1 is closed, the LED light 200 will not illuminate, allowing for efficient use of the battery energy used as the power source. The switch 202 is located near the handle 100 formed on the central shaft 10, allowing the user to immediately press the switch 202 even while gripping the handle 100 and supporting the self-defense umbrella 1.

[0020] When switch 202 is pressed while the light is off, power is supplied from power supply 22 to the LED light 200, causing the LED light 200 to illuminate. Pressing switch 202 again causes the LED light 200 to blink, and pressing it a third time stops the illumination. The blinking of the LED light 200 is rapid, making the emitted light appear brighter. Power supply 22 supplies power to the LED light 200. Power supply 22 is located inside the handle 100.

[0021] Figure 3 illustrates the direction of light emitted from the self-defense umbrella 1 and the direction in which the self-defense umbrella 1 should be pointed. As illustrated in Figure 3, the direction in which light is emitted from the tip 12 of the self-defense umbrella 1 coincides with the direction from the handle 100 towards the tip 12 on the central shaft 10. Therefore, the user can shine light towards an attacker by gripping the handle 100 and pointing the central shaft 10 toward the tip 12. Furthermore, pointing the tip 12 toward an attacker means that the user's body is inside the sheet portion 18 stretched over the main ribs 14, thus also providing self-defense through the sheet portion 18.

[0022] Figure 4 is a flowchart illustrating how to use the self-defense umbrella 1 (S10). As illustrated in Figure 4, in step 100 (S100), the user opens the self-defense umbrella 1 with the tip 12 pointed at the assailant. In step 105 (S105), the user presses switch 202. In step 110 (S110), the power supply 22 supplies power to the LED light 200, which causes light to penetrate the inside of the tip 12. The penetrating light is shone from the translucent material inside the tip 12 towards the assailant.

[0023] In step 115 (S115), if the user presses switch 202 again (S115: Yes), the method of using the self-defense umbrella 1 (S10) proceeds to S120. If the user does not press switch 202 again (S115: No), illumination from the LED light 200 continues. In step 120 (S120), the LED light 200 flashes. In step 125 (S125), if the user presses switch 202 again (S125: Yes), the method of using the self-defense umbrella 1 (S10) proceeds to S130. If the user does not press switch 202 again (S125: No), the flashing light from the LED light 200 continues. In step 130 (S130), the power supply 22 stops supplying power to the LED light 200.

[0024] As described above, with the self-defense umbrella 1 of this embodiment, by pointing the tip 12 at an assailant and pressing the switch 202, the assailant can be blinded. Also, since a distance equal to the length of the central shaft 10 is maintained between the user and the assailant, the user can escape while the assailant is taken aback. Furthermore, even if the assailant attacks with a bladed weapon, the sheet portion 18 of the self-defense umbrella 1 has cut-resistant properties, thus protecting the user. Furthermore, when the self-defense umbrella 1 is closed, it looks just like a normal umbrella, so it doesn't look out of place when installed.

[0025] In the above embodiment, the tip 12 is composed of a light-transmitting member and a non-light-transmitting member. However, if the tip 12 is short, light does not diffuse easily, so the entire tip 12 may be composed of a light-transmitting member.

[0026] (modified version) Figure 5 illustrates a modified example of the self-defense umbrella 3. Note that in Figure 5, the self-defense umbrella 3 is partially shown in perspective to illustrate its structure. Furthermore, in the modified examples, elements having substantially the same function and configuration as those in the above embodiments are denoted by the same reference numerals, thus omitting redundant explanations. In the self-defense umbrella 3 illustrated in Figure 5, the lower ferrule 24 is part of the opening and closing mechanism of the self-defense umbrella 3. It works in conjunction with the support ribs 16 to support the main ribs 14 and is a mechanism that moves the central shaft 10 up and down when opening and closing the self-defense umbrella 3. The retaining rivet 26 is a component that secures the lower ferrule 24 to the central shaft 10 in the appropriate position. The appropriate position is where the lower ferrule 24 secures the main ribs 14 so that the sheet section 18 is taut when the self-defense umbrella 3 is opened. In the above embodiment, the LED light 200 is positioned inside the tip 12, that is, outside the sheet portion 18, but is not limited to this, and may be positioned inside the sheet portion 18, for example, as illustrated in Figure 5. The inside of the sheet portion 18 refers to the side of the sheet portion 18 that faces the user. Specifically, the LED light 200 may be positioned near the central rod 10, the lower turn 24, or the retaining pin 26, and the light emitted from the LED light 200 may be transmitted from the inside to the outside of the sheet portion 18 and illuminated on the target assailant.
