Abstract

A portable lock mechanism designed to fortify the security of windows, sliding entry doors and hinged doors. The device comprises a base support with a threaded aperture and a mounting section integrates a rotatable linking arm, providing a foundation for the suction cup mounting base component. This suction cup mounting base forms a pivotal part of the locking mechanism. A rotatable lever concentric to the suction cup mounting pad and linking arm facilitates easy attachment to window panes or the flat surface of a door. A screw clamp with a threaded shank and adjustable pad ensures adaptability to various offset thicknesses, providing a universal application. Notably, the suction cup, when secured to a window pane or door panel, provides a robust locking system.

Claims (18)

1 . A portable lock mechanism comprising:

a base support having a proximal end and a distal end defining an upper surface and a lower surface, said proximal end including a threaded aperture extending from said upper surface to said lower surface;

a mounting section positioned substantially perpendicular to said distal end of said base support;

a suction cup mounting base secured to said mounting section having a lower surface and an upper surface;

a suction cup coupled concentrically to said lower surface of said suction cup mounting base operatively associated with a rotatably attached lever positioned on said upper surface wherein said lever is rotated for operation of said suction cup; and

a screw clamp rotatably coupled to said base support aperture, said screw clamp having a threaded shank with a handle coupled to a proximal end and an adjustable pad secured to a distal end of said shank;

wherein said suction cup is releasably secured to a window pane or door used in combination with said adjustable screw to inhibit the movement thereof.

2 . The portable lock mechanism according to claim 1 , wherein said mounting section includes a linking arm between 1 inch and 3 inches in length.

3 . The portable lock mechanism according to claim 1 , wherein said suction cup is a substantially flat, circular disc that is slightly larger than said suction cup mounting base.

4 . The portable lock mechanism according to claim 1 , wherein said suction cup is made from a silicone type material having ultraviolet inhibitors.

5 . The portable lock mechanism according to claim 1 , wherein said suction cup mounting base includes a ramp disposed on said upper surface, starting from the center of said suction cup mounting base and extending to an outer edge of said mounting base.

6 . The portable lock mechanism according to claim 1 , wherein said screw clamp includes a threaded nut displaced between said upper surface of said base support and the lower end of said handle and acts as a preventative stop from misadjusting.

7 . The portable lock mechanism according to claim 1 , wherein said adjustable pad is made of rubberized material so as not to scratch a window pane.

8 . The portable lock mechanism according to claim 1 , wherein suction cup mounting base is constructed of a material selected from the group consisting of: aluminum, steel, reinforced fiberglass, plastic, or any combinations thereof.

9 . The portable lock mechanism according to claim 1 , wherein said lock mechanism includes multiple suction cup mounting pads, wherein said lock mechanism can be secured to a window or sliding door in multiple locations.

10 . The portable lock mechanism according to claim 1 , wherein said mounting base includes a sensor for motion sensing, providing audible and visual alarming.

11 . The portable lock mechanism according to claim 1 , wherein said mounting base includes a sensor for motion sensing, providing videography recording.

12 . The portable lock mechanism according to claim 1 , wherein said mounting base is rotatably secured to said base support, wherein said suction cup is securable to an outwardly extending offset on a hinged door or rotated 180 degrees for securement to an inwardly extending offset on a hinged door.
