Benefits of technology

[0024] In the adjustable sight assembly of the present invention, the vertical tilt member carries a horizontal slide which preferably includes or defines a sighting notch that is translatable in the horizontal, or windage, direction by use of a click-detent windage adjustment screw. The windage adjustment screw also has a flanged head adapted to engage or to cooperate with a detent mechanism to thereby provide a positive click adjustment, give the user feedback and to maintain a zero setting of the sight during rugged use of the firearm. The horizontal slide member has a lower slide sleeve. The interior of the cylindrical sleeve is threaded to receive and to cooperate with the threaded windage adjustment screw. The windage adjustment screw moves the cylindrical sleeve of the horizontal slide member left and right laterally through an adjustment range, as provided by a slot which is defined in the vertical tilt member. The windage adjustment screw is kept in place by a threaded member or nut which is received in a circular receiving socket or aperture on the side of the vertical tilt member. The depth of the socket is substantially equal to the thickness of the nut so that the nut is sunken within the side wall to provide a flush fit. The windage adjustment screw has first and second outer diameters, with the distal end of the windage adjustment screw having a smaller diameter than the majority of the length of the elevation adjustment screw body which is received in the threaded sleeve. The smalle...

Problems solved by technology

While the combat sights of the prior art do provide a smooth and snag-free draw, a clear sight picture and rugged service, they do not provide the adjustability many have come to enjoy when using target pistols equipped with adjustable target sights.
Adjustments for windage have required the shooter to strike the side of the sight with a pin punch and hammer, to force the sight laterally in the notch, a procedure which does not permit fine adjustment.
Target sights are also relatively fragile, and may move out of adjustment if a pistol is dropped or struck.
Both of these results present an unsatisfactory result if the firearm is to be used in life-threatening situations.
In the prior sights, there has been an issue of durability, particularly among high volume users.
In the course of thousands of violent reciprocations of the slide, to which the rear sight is attached, that web ma...

first embodiment

[0057] The horizontal windage slide 106 is supported on the vertical tilt member 104 by the cooperative engagement of the tilt member upper facets 200 and 202 with the lower facets 206 and 208 of the horizontal windage slide 106. These cooperating supporting facets are, as seen in FIGS. 4 and 5b cooperatively inclined so that they support the horizontal slide 106 on the vertical tilt member in a manner which will ensure that the horizontal slide 106 cannot rock or pivot fore or aft in response to the almost violent reciprocation of the slide 28 during firing of the pistol 20. In prior devices, the connecting web 198, or its equivalent structure, in previous configurations, was the sole support of the upper portion of the horizontal windage slide; i.e. the upper slide body 186. When the pistol slide 28 reciprocated, that connecting web was subjected to substantial force. Even though it is made, at least in applicant's device, of a high grade steel alloy, it was possible, after repeat...

embodiment 500

[0067] The horizontal windage slide 506 of the fourth preferred embodiment 500 of the adjustable night sight, in accordance with the present invention, has a windage slide body 526 that carries a sighting notch 530. While not specifically depicted in FIG. 13, it will be understood that the windage slide body 526 carries a slide sleeve 538 on a forward or front face 540. That slide sleeve 538 is the same in structure and function, as the slide sleeve 188 which was discussed in connection with FIG. 4. It is received in the transverse chamber 510 and is used to attach the horizontal windage slide 506 to the vertical tilt member 504.

[0068] As may be seen in FIG. 13, and also in FIG. 14, the horizontal windage slide 506 has a faceted front face 540. This front face has three facets 542, 544 and 546, as seen in FIG. 14. These three windage slide facets 542, 544 and 546 are complementary to the three vertical tilt member rear wall facets 518, 520 and 522. The result is again the secure sup...

Abstract

An adjustable night sight for a pistol includes a sight base, a vertical tilt member and a horizontal windage slide. The three components form the adjustable night sight which can be mounted on a slide of a pistol. Sources of luminescence are used to define a rear sight notch. The adjustable night sight horizontal windage slide is supported very securely on the vertical tilt member so that it will not fail under high stress loads. The overall sight assembly is very smooth and compact. It provides much greater resistance to snagging than has been exhibited in prior sight assemblies.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This U.S. patent application claims the benefit, under 35 USC 119e and 120 of U.S. provisional patent application No. 60 / 748,179, filed Dec. 8, 2005. That provisional patent application is related to pending U.S. patent application Ser. No. 10 / 922,918. The disclosures of these applications are expressly incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention is directed generally to a rear sight assembly that is adapted for use with a pistol. More specifically, the present invention is directed to an adjustable rear sight assembly which is adjustable for both elevation and windage. More specifically the present invention is directed to an elevation and windage adjustable night sight for a pistol. [0003] The adjustable night sight in accordance with the present invention includes a sight base that is configured to be received in a Novak-type notch on the upper surface of the pistol's slide. The windage adjust...
