Abstract
Cam lever mounts, devices, systems and methods with pivotable/foldable levers for attaching grips, sights, flashlights to picatinny rails on firearms. A moveable mount having one side with an upper and lower shroud covers has a space therebetween. A lever pivotally attached in the space moves from open to closed positions with substantial portions of the lever protected by the upper and lower shroud covers. The lever pivoting end can be attached to one end of an elongated member with other end attached to a stationary mount so that rotating the lever from open to closed draws the moveable mount toward the stationary mount. Inner sides of the moveable and stationary mounts can have clamp edges facing one another which can attach and detach to the picatinny rails.
Claims19
A cam lock assembly, comprising:
- a moveable cam lever housing having one side with an upper shroud cover having a continuously curved perimeter and a lower shroud cover having a continuously curved perimeter, with a space therebetween and another side having an inwardly facing clamp edge;
- a lever arm having a pivoting end and a free tip end with an elongated arm portion between the pivoting end and the free tip end, the pivoting end being attached within the space between the upper shroud cover and the lower shroud cover, the elongated arm portion having a similar curved perimeter to the continuously curved perimeter on the upper shroud and the continuously curved perimeter on the lower shroud;
- a stationary member having an inner side with an inwardly facing clamp edge, so that the clamp edge on the moveable housing faces the clamp edge on the stationary member;
- and
- an elongated member for attaching the moveable housing to the stationary member, wherein rotating the lever arm from an open position to a closed position moves the lever arm so that the elongated arm portion is covered and protected by each of the upper shroud cover and the lower shroud cover, and wherein the cam lock assembly is adapted to be attached to an accessory in order to attach and detach the accessory by clamping and unclamping the clamp edges to mounting rails attached to a firearm.

A method of protecting lever arms in cam lever assemblies comprising the steps of:
- providing a moveable cam lever housing having one side with an upper shroud cover having a continuously curved perimeter and a lower shroud cover having a continuously curved perimeter, with a space therebetween and another side having an inwardly facing clamp edge;
- providing a lever arm having a pivoting end and a free tip end with an elongated arm portion between the pivoting end and the free tip end, the elongated arm portion having a similar curved perimeter to the continuously curved perimeter on the upper shroud and the continuously curved perimeter on the lower shroud;
- attaching the pivoting end of the lever arm within the space between the upper shroud cover and the lower shroud cover;
- providing a stationary member having an inner side with an inwardly facing clamp edge, so that the clamp edge on the moveable housing faces the clamp edge on the stationary member;
- and
- attaching the moveable housing to the stationary member;
- and
- rotating the lever arm from an open position with a free tip end of the elongated lever arm portion with free tip end exposed outside of the space between the upper shroud cover and the lower shroud cover, to a closed position where the elongated lever arm portion is covered and protected within each of the upper shroud cover and the lower shroud cover, and wherein the cam lock assembly is adapted to be attached to an accessory in order to attach and detach the accessory by clamping and unclamping the clamp edges to mounting rails attached to a firearm.

A cam lock assembly, comprising:
- a first cam lever housing having one side with an upper shroud cover having a continuously curved perimeter and a lower shroud cover having a continuously curved perimeter, with a space therebetween and another side having an inwardly facing clamp edge;
- a lever arm having a pivoting end and a free tip end with an elongated arm portion between the pivoting end and the free tip end, the pivoting end being attached within the space between the upper shroud cover and the lower shroud cover, the elongated arm portion having a similar curved perimeter to the continuously curved perimeter on the upper shroud and the continuously curved perimeter on the lower shroud;
- a cam member having an inner side with an inwardly facing clamp edge, so that the clamp edge on the housing faces the clamp edge on the cam member;
- and
- an elongated member for attaching the housing to the cam member, wherein rotating the lever arm from an open position to a closed position moves the lever arm so that the elongated arm portion is covered and protected by each of the upper shroud cover and the lower shroud cover, and wherein the cam lock assembly is adapted to be attached to an accessory in order to attach and detach the accessory by clamping and unclamping the clamp edges to mounting rails attached to a firearm.
