Abstract
A clamping wall hook for securing to one brick of a brick wall, or any suitable wall structure having a top surface and a bottom surface. The wall hook includes a body having lower teeth positioned to engage the bottom surface of the brick, an upper jaw member having upper teeth for engaging the top surface of the brick. A handle is pivotally attached to the body between a locked and unlocked position and includes a hook structure that can be used to support hanging items. The upper jaw member is pivotally attached to the handle so that a clamping force is generated on the brick when the handle is positioned in the locked position, and released when the handle is positioned in its unlocked position.
Claims18
1) A clamping wall hook for selectively securing to a brick, the brick being of the type including a front face, a top surface and a bottom surface, and defining a first distance measured between the top surface and the bottom surface, the wall hook comprising:
- a base, having lower teeth adapted to selectively engage the bottom surface of the brick, the lower teeth being located within a gripping plane;
- a handle, pivotally attached to the base along a first axis between a locked position and an unlocked position, the handle including a hook;
- an upper jaw member, pivotally attached to the handle along a second axis and having upper teeth adapted to selectively engage the top surface of the brick, the upper teeth being positionable within the gripping plane, the second axis rotating about the first axis when the handle pivots between its locked and unlocked positions, the upper teeth are spaced apart from the lower teeth a second distance which is greater than the first distance when the handle is in the unlocked position and when lower and upper teeth are aligned within the gripping plane, the upper teeth are spaced apart from the lower teeth a third distance which is less than the first distance when the handle is in the locked position and when lower and upper teeth are aligned within the gripping plane, the upper jaw member further having a spring for forcing the upper teeth towards the lower teeth, thereby allowing the wall hook to selectively grip onto the top and bottom surfaces of the brick.
9) A clamping wall hook for selectively securing to a brick, the brick being of the type including a front face, a top surface and a bottom surface, and defining a first distance measured between the top surface and the bottom surface, the wall hook comprising:
- a base, having lower teeth adapted to selectively engage the bottom surface of the brick;
- a handle, pivotally attached to the base between a locked position and an unlocked position, the handle including a hook;
- an upper jaw member having upper teeth adapted to selectively engage the top surface of the brick, the upper jaw member pivotally attached to the handle so that when the handle is in the unlocked position, the distance between the upper and lower teeth is greater than the first distance, and when the handle is in the locked position, the distance between the upper and lower teeth is less than the first distance;
- and
- a spring bias arranged to force the upper teeth towards the lower teeth, thereby allowing the wall hook to selectively grip onto the top and bottom surfaces of the brick, when the handle is in the locked position.
17) A clamping wall hook for selectively securing to a wall structure, the wall structure including a front face, a top surface and a bottom surface, and defining a first distance measured between the top surface and the bottom surface, the wall hook comprising:
- a base, having lower teeth adapted to selectively engage the bottom surface of the wall structure;
- a handle, pivotally attached to the base between a locked position and an unlocked position, the handle including a hook;
- an upper jaw member having upper teeth adapted to selectively engage the top surface of the wall structure, the upper jaw member pivotally attached to the handle so that when the handle is in the unlocked position, the distance between the upper and lower teeth is greater than the first distance, and when the handle is in the locked position, the distance between the upper and lower teeth is less than the first distance;
- and
- a spring bias arranged to force the upper teeth towards the lower teeth, thereby allowing the wall hook to selectively grip onto the top and bottom surfaces of the wall structure, when the handle is in the locked position.
