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, Kafe, Webinar 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.

A counting mechanism for detecting and registering the number of rounds fired from a recoil gun includes a housing that can be mounted to a component of the gun that exhibits recoil motion upon firing of a round. A counting device is contained within the housing and includes an actuator that is activated by the recoil motion of the gun component upon a round being discharged. A weighted mass is movable within the housing with the recoil motion of the gun component, and the actuator is operably configured with the mass such that movement of the mass resul...

What is claimed is: 1. A counting mechanism for detecting and registering the number of rounds fired from a recoil gun, said mechanism comprising: a housing, said housing having a shape and configuration for mounting to a barrel of the gun; a counting device contained within said housing, said counting device indexed by recoil action of the gun barrel upon a round being discharged; and a movable weighted mass within said housing such that relative movement between said housing and said mass results with the recoil action of the gun barrel, said counting device operably configured with said mass such that the relative movement of said mass upon discharge of a round from the barrel causes indexing of said counting device; wherein said counting device comprises an incrementing geared counter, and an actuator configured with said geared counter to cause indexing of said geared counter, said actuator operably configured with said weighted mass so as to be actuated by relative movement of said weighted mass to a defined position relative to said housing in response to the recoil action; and wherein said geared counter and actuator are movably mounted within said housing and constitute at least a component of said weighted mass. 2. The counting mechanism as in claim 1, wherein said geared counter is linearly slidable within said housing, and said actuator is movable in a direction transverse to movement of said counter in order to actuate said counter. 3. The counting mechanism as in claim 2, further comprising a cam track defined within said housing along which said actuator moves upon linear movement of said counter, said cam track moving said actuator in said transverse path. 4. The counting mechanism as in claim 2, further comprising a spring disposed within said housing to oppose movement of said counter in response to the recoil action. 5. The counting mechanism as in claim 2, further comprising a bumper disposed within said housing to arrest return movement of said counter after recoil of the gun barrel. 6. The counting mechanism as in claim 1, wherein said counting device comprises a visual display of a total count of rounds fired, said visual indication externally viewable through a window in said housing. 7. The counting mechanism as in claim 1, further comprising a spring disposed within said housing to oppose motion of said weighted mass in response to the recoil action, said spring having a stiffness selected as a function of the weight of the weighted mass and intensity of the recoil action such that the counting device is actuated only upon an actual firing of a round. 8. The counting mechanism as in claim 7, wherein said spring continuously compresses over the entire recoil duration of the gun barrel. 9. The counting mechanism as in claim 8, wherein stored energy in said spring returns said weighted mass to an at-rest position after the recoil action. 10. The counting mechanism as in claim 1, wherein said housing comprises a base member and a cover member, said cover member hermetically sealed to said base member. 11. A counting mechanism for detecting and registering the number of rounds fired from a recoil gun, said mechanism comprising: a housing, said housing having a shape and configuration for mounting to a component of the gun exhibiting recoil from firing a round; a counting device contained within said housing, said counting device incremented by recoil motion of the gun component upon a round being discharged; means within said housing for transferring recoil movement of the gun component to said counting device such that said counting device is incremented for each round fired; wherein said means for transferring comprises a weighted mass movable within said housing such that relative movement is produced between said housing and weighted mass in response to the recoil action, said relative movement causing said mass to increment said counting device; and wherein said weighted mass includes components of said counting device. 12. The counting mechanism as in claim 11, wherein said counting device comprises an incrementing counter and associated actuator that are linearly slidable within said housing in response to the recoil action, said actuator being actuated at a defined position of said counter within said housing. 13. The counting mechanism as in claim 12, wherein said means for transferring further comprises a cam track defined within said housing along which said actuator is driven as said counter moves relative to said housing. 14. A counting mechanism for detecting and registering the number of rounds fired from a recoil gun, said mechanism comprising: a housing, said housing having a shape and configuration for mounting to a component of the gun exhibiting recoil from firing a round; a counting device contained within said housing, said counting device incremented by recoil motion of the gun component upon a round being discharged; means within said housing for transferring recoil movement of the gun component to said counting device such that said counting device is incremented for each round fired; wherein said means for transferring comprises a weighted mass movable within said housing such that relative movement is produced between said housing and weighted mass in response to the recoil action, said relative movement causing said mass to increment said counting device; wherein said weighted mass is operably configured with an actuator that increments said counting device at a defined position of said weighted mass within said housing; and wherein said means for transferring further comprises a cam track along which said actuator is driven with relative movement of said counter, said cam track defining a path resulting in actuation of said actuator.
