Abstract

A pivoting mount for a weapon accessory includes a base configured to attach to a weapon, an upper member, and a pivot shaft pivotally securing the upper member to the base. The upper member pivots between a use position and a storage position. The mount includes a first damping element disposed between the shaft and the base.

Claims

1. A pivoting mount for a weapon accessory, comprising

a base configured to attach to a weapon, the base having a lower surface and an upper surface, the lower surface configured to engage the weapon, the base having a fore support and an aft support, the supports each having an aperture defined therethru, the apertures being aligned along a fore-aft pivot axis;

a pivot shaft engaging the apertures in the supports of the base such that the pivot shaft extends along the pivot axis, the pivot shaft having an aft section engaging the aft support, a fore section engaging the fore support and a mid section defined therebetween, the aft section of the pivot shaft having at least two detents defined therein;

an upper member pivotally secured to the base by the pivot shaft, the upper member having an upper surface for receiving an accessory and an opposed lower surface, the upper member pivoting around the pivot axis between a use position wherein the lower surface of the upper member is adjacent the upper surface of the base and a storage position wherein the lower surface of the upper member is pivoted away from the upper surface of the base, the upper member having a pivot portion with an aperture defined therethru, the aperture receiving the mid section of the pivot shaft;

a first damping element disposed between the shaft and the base, the first damping element comprising two spaced-apart elastomeric rings disposed in the fore aperture of the base and surrounding the fore section of the pivot shaft;

a second damping element disposed between the upper member and the base, the second damping element being at least one elastomeric ring disposed between the pivot portion and one of the supports; and

a retaining assembly operable to selectively retain the upper member in at least the use and storage positions with respect to the base, the retaining assembly including a spring loaded ball engaging the detents in the aft section of the pivot shaft when the upper portion is in the use and storage positions.

2. A pivoting mount in accordance with claim 1, wherein:

the base includes a quick release clamping mechanism operable to engage a rail of a weapon, the mechanism defining the lower surface of the base.

3. A pivoting mount in accordance with claim 1, wherein:

the first damping element further including a spacer disposed between the two spaced-apart elastomeric rings.

4. A pivoting mount in accordance with claim 1, wherein:

the at least one elastomeric ring of the second damping element comprises two elastomeric rings, one of the rings being disposed between the fore support and the pivot portion and the other of the rings being disposed between the aft support and the pivot portion, each of the rings being disposed around the pivot shaft.

5. A pivoting mount in accordance with claim 1, wherein:

the base has a recess defined therein, the recess extending from the aperture in the support; and

the spring loaded ball is disposed in the recess.

6. A pivoting mount in accordance with claim 1, wherein:

the pivot shaft fixedly engages the pivot portion of the upper member such that the upper member and pivot shaft rotate together.

7. A pivoting mount in accordance with claim 1, wherein:

the pivot portion of the upper member further includes a stop flange defined thereon, the stop flange engaging the base when the upper member is in the storage position.

8. A pivoting mount in accordance with claim 1, wherein:

each of the supports extends upwardly from the upper surface of the base.

9. A pivoting mount for a weapon accessory, comprising

a base configured to attach to a weapon;

an upper member;

a pivot shaft having a fore section and an aft section, the pivot shaft pivotally securing the upper member to the base such that the upper member pivots between a use position and a storage position; and

a first damping element disposed between the shaft and the base; and

a second damping element disposed between the upper member and the base, the second damping element comprising two elastomeric rings, one of the rings being disposed around the fore section of the pivot shaft and the other of the rings being disposed around the aft section of the pivot shaft.

10. A pivoting mount in accordance with claim 9, wherein:

the base has a fore support receiving the fore section of the pivot shaft and an aft support receiving the aft section of the pivot shaft, the supports each having an aperture defined therethru, the apertures being aligned along a fore-aft pivot axis;

the upper member having a pivot portion with an aperture defined therethru, the aperture receiving the mid section of the pivot shaft; and

one of the rings being disposed between the fore support and the pivot portion and the other of the rings being disposed between the aft support and the pivot portion.

11. A pivoting mount in accordance with claim 9, wherein:

the base has a fore support receiving the fore section of the pivot shaft and an aft support receiving the aft section of the pivot shaft, the supports each having an aperture defined therethru, the apertures being aligned along a fore-aft pivot axis;

the upper member having a pivot portion with an aperture defined therethru, the aperture receiving the mid section of the pivot shaft; and

the first damping element comprises at least one elastomeric ring disposed in one of the apertures of the base and surrounding the pivot shaft.

12. A pivoting mount in accordance with claim 11, wherein:

the at least one elastomeric ring of the first damping element comprises two elastomeric rings disposed in the fore aperture of the base and surrounding the fore section of the pivot shaft; and

the first damping element further including a spacer disposed between the two elastomeric rings.

13. A pivoting mount in accordance with claim 9, further comprising:

a retaining assembly operable to selectively retain the upper member in at least the use and storage orientations with respect to the base, the retaining assembly including a spring loaded ball engaging the detents in the pivot shaft when the upper portion is in the use and storage orientations.

14. A pivoting mount in accordance with claim 9, wherein:

the base includes a quick release clamping mechanism operable to engage a rail of a weapon, the mechanism defining the lower surface of the base.

15. A pivoting mount for a weapon accessory, comprising

a base configured to attach to a weapon, the base having a lower surface and an upper surface, the lower surface configured to engage the weapon;

an upper member having an upper surface for receiving an accessory and an opposed lower surface;

one of the base or upper member having a fore support and an aft support, and the other of the base or upper member having a mid support, the fore support, aft support and mid support each having an aperture defined therethru, the apertures being aligned along a fore-aft pivot axis;

a pivot shaft engaging the apertures in the supports of the base and upper member such that the pivot shaft extends along the pivot axis, the pivot shaft having an aft section engaging the aft support, a fore section engaging the fore support and a mid section engaging the mid support;

the upper member pivoting around the pivot axis between a use position wherein the lower surface of the upper member is adjacent the upper surface of the base and a storage position wherein the lower surface of the upper member is pivoted away from the upper surface of the base; and
