  • Patent number: 8528146
    Abstract: The present invention discloses a cleaning apparatus which the main body is made up of individual brush sections that are shaped in such a way and attached to one another, that no matter which position it is in, always has a continuous row of bristles making contact with the surface being cleaned, and these sections are attached to each other using hinges, or hinge-like devices, and having constant tension that connects these sections, and allow each individual section to operate independently of one another, while always having the constant spring-like action of returning to a flat-like position when not being applied to contour to any angle or shape other than a flat surface, allowing the user to an easier, faster, and more efficient way to clean a swimming pool or other things alike.

  • Patent number: 7152293
    Abstract: This is a device use for removing a hinge pin from its hinge assembly safely, quickly, and easily, using lever action instead of the traditional hammering or banging. This device is placed over the top of the door hinge, where it rests by grabbing the head of the hinge pin. It has a handle that is attached to a gear wheel, which rotates on a shaft, when the handle is moved up and down. It has an L shaped arm that has a thin rod attached to it lower part. The L shaped arm has teeth on it backside, which interlocks with the gear wheel. When the handle is pulled sown, the gear wheel rotates and raised the L shaped arm. This raises the thin rod that is attached to the L shaped arm, which in turn pushes up against the bottom of the hinge pin, thus raising the hinge pin up and out of the door hinge assembly.
