Cam lever mount
View Patent ↗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.
1. 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.
2. The cam lock assembly of claim 1 , wherein the clamp edge on the moveable housing and the clamp edge on the stationary member are adapted to clamp about picatinny rails.
3. The cam lock assembly of claim 1 , wherein the pivoting end of the lever arm is pivotally attached to one end of the elongated member.
4. The cam lock assembly of claim 3 , wherein the elongated member includes:
another end with threads for being threadably attached to the stationary member.
5. The cam lock assembly of claim 1 , wherein each of the upper shroud cover and the lower shroud cover have outwardly facing generally curved convex perimeter edges.
6. The cam lock assembly of claim 5 , wherein each of the upper shroud cover and the lower shroud cover have a rounded outer edge.
7. The cam lock assembly of claim 5 , wherein the lever arm includes:
a generally curved convex side; and
a generally curved concave side, wherein the generally curved convex side fits within the generally curved convex perimeter edges of the upper shroud cover and the lower shroud cover when the lever arm is in a closed position.
8. The cam lock assembly of claim 1 , wherein the lever arm is a right hand moving lever arm.
9. The cam lock assembly of claim 1 , wherein the lever arm is a left hand moving lever arm.
10. 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.
11. The method of claim 10 , further comprising the step of:
clamping the clamp edge on the moveable housing and the clamp edge on the stationary member about picatinny rails on the another member.
12. The method of claim 10 , further comprising the step of:
pivotally attaching the pivoting end of the lever arm to one end of the elongated member.
13. The method of claim 12 , further comprising the step of:
attaching an opposite threaded end of the elongated member to be threadably attached to the stationary member.
14. The method of claim 10 , further comprising the step of:
providing each of the upper shroud cover and the lower shroud cover with outwardly facing generally curved convex perimeter edges.
15. The method of claim 14 , further comprising the step of:
providing each of the upper shroud cover and the lower shroud cover with a rounded outer edge.
16. The method of claim 10 , further comprising the steps of:
providing the lever arm a generally curved convex side and a generally curved concave side; and
fitting the generally curved convex side of the lever arm within the generally curved convex perimeter edges of the upper shroud cover and the lower shroud cover when the lever arm is in a closed position.
17. The method of claim 10 , further comprising the step of:
providing the lever arm as a right hand moving lever arm.
18. The method of claim 10 , further comprising the step of:
providing the lever arm as a left hand moving lever arm.
19. 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.
