Abstract

A laser sight is embedded in a mounting rail otherwise used for attaching accessories to small arms discharge devices such as pistols or rifles. The mounting rail has a transverse profile that extends along an axis of the mounting rail for engaging mating features of the accessories. The laser sight is located at least partly within the transverse profile of the mounting rail and has a sighting axis that extends substantially parallel to the axis of the mounting rail.

Claims (34)

1. An accessory mount for a small-arm dischargeable device comprising

a dovetail rail for mounting an accessory,

tapered sidewalls of the dovetail rail extending along a longitudinal axis of the dovetail rail and being spaced apart along an orthogonal transverse axis of the dovetail rail in positions for engaging mating sidewalls of a dovetail receptor formed in the accessory,

a pedestal of the dovetail rail having opposite sides that extend along the longitudinal axis adjacent to the tapered sidewalls of the dovetail rail in a form that provides clearance for the mating sidewalls of the dovetail receptor to engage the tapered sidewalls of the dovetail rail, and

a laser sight embedded in the dovetail rail in a position substantially aligned with the longitudinal axis of the dovetail rail and positioned directly between at least one of (a) the tapered sidewalls and (b) the sides of the pedestal.

2. The accessory mount of claim 1 in which the laser sight is centered directly between the tapered sidewalls of the dovetail rail.

3. The accessory mount of claim 2 in which the tapered sidewalls of the dovetail rail have opposing V-shaped profiles with apices aligned along the transverse axis.

4. The accessory mount of claim 1 in which the laser sight includes a beam generator and a collimating optic aligned by a common housing.

5. An accessory mount for a small-arm dischargeable device comprising

a dovetail rail for mounting an accessory,

tapered sidewalls of the dovetail rail extending along a longitudinal axis of the dovetail rail and being spaced apart along an orthogonal transverse axis of the dovetail rail in positions for engaging mating sidewalls of a dovetail receptor formed in the accessory,

a laser sight embedded in the dovetail rail in a position substantially aligned with the longitudinal axis of the dovetail rail and positioned along the transverse axis of the dovetail rail at least partly between the tapered sidewalls,

the laser sight including a beam generator and a collimating optic aligned by a common housing, and

the tapered sidewalls overhanging opposite sides of a pedestal that supports the tapered sidewalls.

6. The accessory mount of claim 5 in which the common housing is embedded within a space that includes both a space directly between the tapered sidewalls and a space directly between the sides of the pedestal.

7. The accessory mount of claim 6 in which the common housing is entirely embedded within the space directly between the tapered sidewalls.

8. The accessory mount of claim 6 in which a first portion of the common housing is embedded within the space directly between the tapered sidewalls and a second portion of the common housing is embedded in the space directly between the sides of the pedestal.

9. The accessory mount of claim 1 in which the dovetail rail is formed integrally with the small-arm dischargeable device.

10. The accessory mount of claim 1 further comprising a clamp for attaching the dovetail rail to the small-arm dischargeable device.

11. The accessory mount of claim 10 in which the clamp includes features for engaging a barrel of the small-arm dischargeable device.

12. An accessory mount for a small-arm dischargeable device comprising

a dovetail rail for mounting an accessory,

tapered sidewalls of the dovetail rail extending along a longitudinal axis of the dovetail rail and being spaced apart along an orthogonal transverse axis of the dovetail rail in positions for engaging mating sidewalls of a dovetail receptor formed in the accessory, and

a laser sight embedded in the dovetail rail in a position substantially aligned with the longitudinal axis of the dovetail rail and positioned along the transverse axis of the dovetail rail at least partly between the tapered sidewalls,

wherein the dovetail rail is formed as a part of an adapter that presents the dovetail rail as a secondary mount and has a receptor for engaging a primary mount on the dischargeable device.

13. The accessory mount of claim 12 in which the adapter receptor is a dovetail receptor for engaging a dovetail rail attached to the dischargeable device as the primary mount.

14. The accessory mount of claim 1 in which the dovetail rail is formed as a part of an adapter that presents the dovetail rail as a secondary mount and has a receptor for engaging a primary mount on the dischargeable device.

15. An accessory mount for a small-arm dischargeable device comprising

a dovetail rail for mounting an accessory,

tapered sidewalls of the dovetail rail extending along a longitudinal axis of the dovetail rail and being spaced apart along an orthogonal transverse axis of the dovetail rail in positions for engaging mating sidewalls of a dovetail receptor formed in the accessory, and

a laser sight embedded in the dovetail rail in a position substantially aligned with the longitudinal axis of the dovetail rail and positioned along the transverse axis of the dovetail rail at least partly between the tapered sidewalls,

wherein an outer land surface of the dovetail rail interconnects the tapered sidewalls, and

a battery compartment for supplying power to the laser sight is formed in the dovetail rail through the outer land surface.

16. The accessory mount of claim 15 in which a repositionable cover for the battery compartment forms a portion of the outer land surface of the dovetail rail.
