The self defense umbrella 100 (hereinafter invention) is a safety device. The invention 100 is configured for use with a person. The invention 100 forms a defensive shield 101 that blocks and deflects an offensive projectile 191 directed at the person using the invention 100. The invention 100 comprises a shield 101 and a control system 102. The shield 101 forms a physical barrier that blocks and deflects an offensive projectile 191 directed at the person using the invention 100.

The control system 102: 1) captures images of the environment of the person using the invention 100; 2) determines the GPS coordinates of the person using the invention 100; 3) transmits the captured images and the GPS coordinates to an appropriate authority 172; 4) illuminates the environment of the person using the invention 100; and, 5) operates a defensive firearm 128 incorporated into the invention 100. Each invention 100 further comprises an interlocking mechanism that allows a plurality of inventions 100 to be interlocked to expand the volume of the protected space relative to the space protected by any individual self defense umbrella. The appropriate authority 172 is discussed in greater detail elsewhere in this disclosure.

The shield 101 is a vertical barrier structure. The shield 101 is a collapsible structure built in the structure of an umbrella. The shield 101 forms a physical barrier that blocks and deflects blows and projectiles directed at the person using the invention 100. The shield 101 is a paraboloid structure. The shield 101 is further defined with a focal point 194, a concave surface 195, and a convex surface 196. The focal point 194 is the mathematical focal point 194 of the paraboloid structure of the shield 101. During normal use of the invention 100, the concave surface 195 of the shield 101 is proximal to the person using the invention 100. The convex surface 196 is the surface of the paraboloid structure that is distal from the person using the invention 100.

As shown most clearly in FIG. 9, the paraboloid structure of the shield 101 forms a reflective surface that deflects an offensive projectile 191 that is directed at the person using the invention 100 such that: 1) the incident angle 192 of contact of the offensive projectile 191 equals the reflected angle 193 of the deflected offensive projectile 191; and 2) the vector formed by the reflected angle 193 deflects the offensive projectile 191 in a direction away from the focal point 194 of the paraboloid structure of the shield 101.

Designing the paraboloid structure of the shield 101 in this manner creates a safe zone for the person using the invention 100 when the focal point 194 of the shield 101 is placed directly between the person using the invention 100 and the source of the offensive projectile 191.

The shield 101 comprises a canopy 111 and a frame 112.

The canopy 111 is a structure that absorbs and deflects the kinetic energy of the offensive projectile 191 in a direction away from the safe zone of the shield 101. The canopy 111 is a sheeting structure that forms the surface of the paraboloid structure when the invention 100 fully deploys. The canopy 111 attaches under tension to the frame 112.

The frame 112 is a titanium structure that holds and maintains the canopy 111 in the shape of the paraboloid structure when the invention 100 fully deploys. The physical structure of the frame 112 closely follows the physical structure of an umbrella. Any modifications to the frame 112 relative to a standard umbrella frame are intended to reinforce the frame 112 to withstand the kinetic energies to which the shield 101 is subjected. The frame 112 comprises a plurality of ribs 141, a plurality of stretchers 142, a runner 143, a center shaft 144, and a handle 145.

The canopy 111 comprises a plurality of panels 131. Each individual panel selected from the plurality of panels 131 comprises a plurality of textiles 132, a plurality of deflection plates 133, and a magnet 134. The plurality of textiles 132 comprises an outer textile layer 181, one or more protective textile layers 182, and a base textile layer 183.

The canopy 111 is assembled from the plurality of panels 131. The plurality of panels 131 is a collection of individual panels of a roughly triangular shape. Each individual panel selected from the plurality of panels 131: 1) is designed to absorb energy from the offensive projectile 191; and, 2) is designed to deflect the offensive projectile 191 in a direction away from the focal point 194 of the shield 101. Each individual panel selected from the plurality of panels 131 is a composite textile.

The plurality of textiles 132 comprises a minimum of three sheeting layers. Each sheeting layer contained within the plurality of textiles 132 is designed to: 1) absorb energy from the offensive projectile 191; 2) deflect the offensive projectile 191; and, 3) contain the plurality of deflection plates 133 within the individual panel. In the first potential embodiment of the disclosure, each of the plurality of textiles 132 comprises a commercially available poly-para-phenylene terephthalamide (CAS 25035-37-4) based textile. Methods to design, manufacture, and assemble ballistic materials as described in this paragraph are well known and documented in the textile and apparel arts.

Each of the one or more protective textile layers 182 is a commercially available textile that is specifically designed to deflect the energy of an offensive projectile 191. Each of the one or more protective textile layers 182 is positioned between the plurality of deflection plates 133 and the outer textile layer 181. The base textile layer 183 is a commercially available textile that is specifically designed to deflect the energy of an offensive projectile 191. Each of the plurality of deflection plates 133 attaches to the base textile layer 183.

As shown most clearly in FIG. 7, the plurality of deflection plates 133 are layered between two adjacent textiles selected from the plurality of textiles 132. Each of the plurality of deflection plates 133 is a rigid plate structure that performs the function of armor. The plurality of deflection plates 133 forms a surface within each individual panel that absorbs and deflects the energy of the offensive projectile 191. As shown most clearly in FIG. 6, the plurality of deflection plates 133 are assembled in the manner of a mosaic in the sense that smaller individual plates are placed next to each other. The mosaic structure of the plurality of deflection plates 133 maximizes the surface area protected by the plurality of deflection plates 133 within the individual panel while allowing the individual panel to remain flexible within the overall structure of the canopy 111.

The magnet 134 is a neodymium magnet. The magnet 134 attaches to the individual panel along the section of the individual panel that forms the outer perimeter of the canopy 111. The magnet 134 of a first instantiation of the invention 100 is intended to attach to the magnet 134 of a second instantiation of the invention 100. By interconnecting the magnets 134 of two separate instantiations of the invention 100, multiple instantiations of the invention 100 may be joined to create a safe zone of increased size relative to the safe zone that is achievable by a single instantiation of the invention 100.

The canopy 111 is assembled by joining two panels to each rib selected from the plurality of ribs 141. Each of the plurality of ribs 141 joins a first panel selected from the plurality of panels 131 to a second panel selected from the plurality of panels 131. Each of the plurality of ribs 141 is identical. Each of the plurality of ribs 141 is formed such that the canopy 111 forms a paraboloid shape when the canopy 111 deploys. The use of a plurality of ribs 141 in an umbrella structure is well-known in the mechanical arts.

The plurality of switches 125 are control interfaces accessible to the person using the invention 100 to access the control system 102. In the first potential embodiment of the disclosure, the plurality of switches 125 comprises a light switch 151, a trigger switch 152, and a deployment switch 153. The light 126 is a lamp that is used to illuminate the space in front of the convex surface 196 of the shield 101. The light 126 is controlled using a light switch 151.

The light switch 151 is a normally open momentary switch that electrically connects in series between the battery 129 and a first pull down resistor 154. The light switch 151 signals the logic module 121 to turn on and off the light 126.

The deployment switch 153 is a maintained switch that closes when the canopy 111 deploys. The deployment switch 153 electrically connects in series between the battery 129 and a third pull down resistor 156. The deployment switch 153 signals to the logic module 121 that the operation of the control system 102 should be initiated. The defensive projectile 163 further comprises a laser aiming device 164. The laser aiming device 164 is illuminated by the logic module 121 when the deployment switch 153 is activated.

The voltage across the second pull down resistor 155 is monitored by logic module 121. The third pull down resistor 156 is a pull-down resistor that presents a voltage to the logic module 121 when the deployment switch 153 is closed. The voltage across the third pull down resistor 156 is monitored by the logic module 121.

The image sensor 127 is a sensor that: 1) captures images from the space illuminated by the light 126; 2) generates a digital representation of the captured image; and, 3) transmits the digital representation to the logic module 121 for transmission to the appropriate authority 172.

The firearm 128 is a device that projects a defensive projectile 163 towards the source of an offensive projectile 191. The firearm 128 comprises a compressed gas cylinder 161, a solenoid valve 162, and a defensive projectile 163.

The compressed gas cylinder 161 is a commercially available cylinder of compressed gas that is used to provide a motive force to the defensive projectile 163. The solenoid valve 162 controls the release of the compressed gas contained within the compressed gas cylinder 161. As shown most clearly in FIG. 8, the logic module 121 energizes the coil of the solenoid valve 162 when the trigger switch 152 is closed.

The solenoid valve 162 is not directly operated by the trigger switch 152 for security reasons. Specifically, the logic module 121 will only energize the coil of the solenoid valve 162 after a user has been authorized using the biometric sensor 124. The solenoid valve 162 is sized to allow the compressed gas cylinder 161 to decompress explosively.

The defensive projectile 163 is fired away from the invention 100 using the compressed gas cylinder 161 and the solenoid valve 162. In the first potential embodiment of the disclosure, the defensive projectile 163 is selected from the group consisting of a tear gas canister or the electrodes from a Taser.

The metal detector 230 is a commercially available device. The operation of the metal detector 230 is initiated by the logic module 121. The metal detector 230 generated an audible alarm when metal is detected in front of the convex surface 196 of the shield 101. The metal detector comprises a field generator 231, a field detector 232, and a speaker 233. The field generator 231 generates an electrical field of a known geometry in front of the convex surface 196 of the shield 101. The field detector 232 detects the disruption in the geometry of the electric field when a metal object enters the electric field. When the field detector 232 detects this electric field disruption, the speaker 233 is activated to generate a clearly audible alarm.
