Abstract

An accessory control handgrip apparatus for weapon includes a rail clamp assembly, a grip base extending from the grip base assembly, a grip sleeve slidably received on the grip base, a keypad disposed on the grip sleeve, and one or more connectors for operably coupling the keypad to an accessory device.

First claim

What is claimed is:

1. An accessory control handgrip apparatus for weapon, comprising:
an elongate grip base having a longitudinal axis and a first engagement surface, the first engagement surface extending axially and facing radially outward;
a fastener connected to a proximal end of the grip base, said fastener for removably attaching the handgrip apparatus to a fore-end portion of a weapon;
an elongate grip sleeve having an axially extending bore, the grip base detachably received within the axially extending bore and coaxial with the grip base, the axially extending bore having a second engagement surface, the second engagement surface extending axially and facing radially inward, the second engagement surface slidably engaging the first engagement surface, wherein the first engagement surface is configured to engage the second engagement surface when the grip sleeve is oriented at a plurality of rotational positions with respect to the grip base and wherein the first engagement surface and second engagement surface both have a cross-sectional shape which has an n-fold rotational symmetry about the longitudinal axis, wherein n is an integer greater than or equal to 2;
the elongate grip sleeve having a radially outward facing surface defining a handgrip surface;
at least one keypad comprising a switch disposed on the handgrip surface, the switch for controlling operation of one or more electrically-operated devices associated with the weapon; and
a connector electrically coupled to the switch and configured to electrically couple the switch to the one or more electrically-operated devices.

2. The accessory control handgrip apparatus of claim 1 , wherein n is an integer between 2 and 16.

3. The accessory control handgrip apparatus of claim 1 , wherein n is equal to 8.

4. The accessory control handgrip apparatus of claim 1 , wherein the grip base forms a hollow enclosure which opens at a distal end of the grip base.

5. The accessory control handgrip apparatus of claim 4 , further comprising an end cap removably attached to the distal end of the grip base.

6. The accessory control handgrip apparatus of claim 5 , wherein the end cap comprises internal helical threads complementary with external helical threads on the distal end of the grip base.

7. The accessory control handgrip apparatus of claim 5 , wherein the end cap engages a distal end of the grip sleeve to secure the grip sleeve in a fixed axial position with respect to the grip base.

8. The accessory control handgrip apparatus of claim 5 , further comprising an extended end cap detachably attachable to the distal end of the grip base in place of the end cap to increase an axial extent of a gripping surface of the hand grip apparatus.

9. The accessory control handgrip apparatus of claim 1 , wherein the at least one keypad is detachable from the grip sleeve.

10. The accessory control handgrip apparatus of claim 9 , wherein the grip sleeve includes an integral interface slidably receiving the at least one keypad.

11. The accessory control handgrip apparatus of claim 9 , wherein the at least one keypad comprises a first keypad and a second keypad, wherein the first and second keypads are interchangeably attachable to the grip sleeve.

12. The accessory control handgrip apparatus of claim 1 , further comprising an electrically operated accessory device having a mode of operation actuatable or controllable by the switch, the electrically operated accessory device configured to be detachably secured to the weapon.

13. The accessory control handgrip apparatus of claim 1 , wherein the fastener is a weapon accessory rail clamp.

14. The accessory control handgrip apparatus of claim 13 , wherein the fastener is adapted for removable attachment to a rail interface selected from a Picatinny rail interface.

15. The accessory control handgrip apparatus of claim 10 , wherein the integral interface comprises a pair of opposing axially extending grooves configured to slidably receive a pair of slide rails disposed on the keypad.

16. An accessory control handgrip apparatus for weapon, comprising:
an elongate grip base having a longitudinal axis and a first engagement surface, the first engagement surface extending axially and facing radially outward;
a fastener connected to a proximal end of the grip base, said fastener for removably attaching the handgrip apparatus to a fore-end portion of a weapon;
an elongate grip sleeve having an axially extending bore, the grip base detachably received within the axially extending bore and coaxial with the grip base, the axially extending bore having a second engagement surface, the second engagement surface extending axially and facing radially inward, the second engagement surface slidably engaging the first engagement surface, wherein the first engagement surface and second engagement surface both have a cross-sectional shape which has a 1-fold rotational symmetry about the longitudinal axis to provide a single aligned orientation between the grip base and the grip sleeve;
the elongate grip sleeve having a radially outward facing surface defining a handgrip surface;
at least one keypad comprising a switch disposed on the handgrip surface, the switch for controlling operation of one or more electrically-operated devices associated with the weapon; and
a connector electrically coupled to the switch and configured to electrically couple the switch to the one or more electrically-operated devices.
