  • Publication number: 20250180335
    Abstract: A bulletproof shielding devices and methods for protecting a user from high velocity projectiles such as bullets includes a panel having a front side and a back side. The front side is a raw carbon fiber material bonded with an epoxy resin. The back side is an extended chain polyethylene fiber material blended with the raw carbon fiber material. A bullet resistant material is positioned between the front side and the back side. The bullet resistant material includes at least four layers of an ultra-high-molecular-weight-polyethylene material. The extended chain polyethylene fiber material entangles a projectile being shot at the front side, reducing a force of an impact of the projectile and facilitating the bullet resistant material in stopping the projectile. The raw carbon fiber material exerts a force toward the projectile thereby inhibiting the progression of the projectile. The panel has a weight between 4.5 pounds and 7.5 pounds.

  • Patent number: 9902406
    Abstract: Contemplated ladder assemblies include: a) at least two rails, b) at least one step, wherein each step is coupled to the at least two rails, such that the rails are relatively vertical and the steps are relatively horizontal, c) at least one grappling footing peg, wherein the peg is operationally coupled with a rail, d) at least one safety handle, wherein the handle is coupled with at least one rail, and e) at least one commuter train, passenger train or railway car coupling fixture, wherein the coupling fixture operationally engages with a mating fixture on the commuter train, passenger train or railway car.

  • Publication number: 20160200233
    Abstract: A safety handle kit is disclosed and includes: a rigid and fixed handle component, at least one coupling component, and at least one affixing component, and at least one affixing component, wherein when the handle component is coupled to a seat, bench or combination thereof with the use of the at least one coupling component and the at least one affixing component, it forms a safety handle that is a closed loop. Methods of installing a safety handle kit comprise: providing a rigid and fixed handle component, providing at least one coupling component, providing at least one affixing component, and coupling the handle component to a seat, bench or combination thereof through the coupling component by utilizing the at least one affixing component, wherein when the handle component is coupled to a seat, bench or combination thereof with the use of the at least one coupling component and the at least one affixing component, it forms a safety handle that is a closed loop.
