연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

An improved mounting assembly is provided that is configured to be releasably attached to a standard dovetail rail profile, wherein the initial clamping tension of the clamping actuator is adjustable. The mounting assembly generally includes a main body having a lower portion that is configured to engage a standard dovetail and an upper portion accessory receiving formation. The lower portion of the mounting assembly has a first engagement member extending downwardly along one side thereof for engaging one side of the dovetail rail and a clamping assembly to engage the opposing side of the dovetail rail. At least one spring and a retention nut are provided as part of the clamping assembly such that a retention nut, which is locked relative to the clamping assembly, controls the preset spring tension thereby controlling the clamping force applied by the clamping assembly.

What is claimed is: 1. A mounting assembly for attaching an accessory to a dovetail rail interface on a firearm, said mounting assembly comprising: a body having a lower portion and an upper portion, said lower portion configured to engage a first side of said dovetail rail, said upper portion configured to receive and retain said accessory; a boss formation extending outwardly from a side of said body and including an opening therein; a clamping assembly configured to releasably engage a second side of said dovetail rail, including, a foot portion positioned adjacent a bottom surface of said boss formation, said foot portion including a cam surface; an actuator arm extending outwardly from said foot portion; a shaft extending upwardly from said foot portion through said opening in said boss formation, a terminal end of said shaft being threaded; a spring received around said shaft adjacent the top surface of said boss formation; a retention nut threadedly received on said terminal end of said shaft such that said spring is captured between a bottom surface of said retention nut and a top surface of said boss formation; and a locking pin threadedly received through a bore in said actuator arm, said locking pin configured and arranged to allow a user to positively lock the position of said retention nut on said threaded shaft, wherein movement of said clamping assembly to releasably engage said dovetail rail causes said foot portion to clamp against said second side of said dovetail rail. 2. The mounting assembly of claim 1, wherein said locking pin includes a distal end for engaging the retention nut and a proximal end having threads thereabout, the threads engaging with complimentary threads on the interior of said bore, wherein said locking pin engages said retention nut and prevents accidental rotation of said retention nut relative to said shaft when said locking pin is fully threaded into said bore. 3. The mounting assembly of claim 1, wherein said clamping assembly further comprises a bushing received within said opening in said boss formation, said bushing including an opening, said shaft of said clamping assembly extending through said opening in said bushing, said spring washer being captured between the bottom surface of said retention nut and a top surface of said bushing. 4. The mounting assembly of claim 1, wherein said spring is at least one spring washer. 5. The mounting assembly of claim 1, wherein said spring is a plurality of spring washers. 6. The mounting assembly of claim 1, wherein said spring is a coil spring. 7. The mounting assembly of claim 1, wherein said boss formation includes a shoulder formation configured and arranged to prevent rotation of said actuator arm beyond a disengaged position. 8. The mounting assembly of claim 1, wherein said locking pin includes a shoulder region disposed between a proximal end and a distal end of the locking pin, wherein a retention pin installed through said actuator handle and across said bore prevents removal of said locking pin from said actuator handle. 9. A mounting assembly for attaching an accessory to a dovetail rail interface on a firearm, said mounting assembly comprising: a body having a lower portion and an upper portion, said lower portion configured to engage a first side of said dovetail rail, said upper portion configured to receive and retain said accessory; a boss formation extending outwardly from a side of said body and including an opening therein; a clamping assembly configured to releasably engage a second side of said dovetail rail, including, a foot portion positioned adjacent a bottom surface of said boss formation, said foot portion including a cam surface; a shaft extending upwardly from said foot portion through said opening in said boss formation, a terminal end of said shaft being threaded; a spring received around said shaft adjacent the top surface of said boss formation; an actuator arm positioned around said shaft and above said spring washer, said actuator arm engaged with said shaft such that rotation of said actuator arm causes rotation of said shaft and said camming foot; and a retention nut threadedly received on said terminal end of said shaft such that said actuator arm and said spring are captured between a bottom surface of said retention nut and a top surface of said boss formation; a locking pin threadedly received through a bore in said actuator arm, said locking pin configured and arranged to allow a user to positively lock the position of said retention nut on said threaded shaft; and a buffer pad located adjacent a bottom surface of said lower portion and adjacent said clamping assembly, wherein movement of said clamping assembly to releasably engage said dovetail rail causes said foot portion to clamp said buffer pad against said second side of said dovetail rail. 10. The mounting assembly of claim 9, wherein said locking pin includes a distal end for engaging the retention nut and a proximal end having threads thereabout, the threads engaging with complimentary threads on the interior of said bore, wherein said locking pin engages said retention nut and prevents accidental rotation of said retention nut relative to said shaft when said locking pin is fully threaded in bore. 11. The mounting assembly of claim 9, wherein said clamping assembly further comprises a bushing received within said opening in said boss formation, said bushing including an opening, said shaft of said clamping assembly extending through said opening in said bushing, said spring washer being captured between the bottom surface of said retention nut and a top surface of said bushing. 12. The mounting assembly of claim 9, wherein said spring is at least one spring washer. 13. The mounting assembly of claim 9, wherein said spring is a plurality of spring washers. 14. The mounting assembly of claim 9, wherein said spring is a coil spring. 15. The mounting assembly of claim 9, wherein said boss formation includes a shoulder formation configured and arranged to prevent rotation of said actuator arm beyond a disengaged position.
