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.

1. A dumpster lid opening system comprising; a container having a base plate and a front wall and a rear wall and side walls defining a chamber there between;a lid pivotably coupled to the rear wall;a pivot bar attached to the lid with a long extent attached to the lid and a short extent;an actuator housing with a trolley movable between a top position and a bottom position, a spring urging the trolley to the top position and, a plurality of wheels to move the trolley between the top position and the bottom position;a pedal coupled to the trolley adapted to be depressed by a user to move the trolley to the bottom position; anda connector having an interior end attached to the trolley and an exterior end attached to the short extent of the pivot bar whereby the depression the pedal will move the connector to raise the lid while release of the pedal will cause the spring to lower the lid; andan upper sprocket and a lower sprocket, the sprockets being rotatable in the actuator housing and including a pulley beneath the rear wall wherein the connector includes a cable extending from the pivot bar then extending vertically adjacent to the rear wall then around the pulley and then horizontal beneath the base plate, the connector including a chain coupling from the cable around the lower sprocket and then around the upper sprocket and then to the trolley. 2. A dumpster lid opening system comprising; a container having a base plate and a front wall and a rear wall and side walls defining a chamber there between;a lid pivotably coupled to the rear wall;a pivot bar attached to the lid with a long extent attached to the lid and a short extent;an actuator housing with a trolley movable between a top position and a bottom position, a spring urging the trolley to the top position and, a plurality of wheels to move the trolley between the top position and the bottom position;a pedal coupled to the trolley adapted to be depressed by a user to move the trolley to the bottom position; anda connector having an interior end attached to the trolley and an exterior end attached to the short extent of the pivot bar whereby the depression the pedal will move the connector to raise the lid while release of the pedal will cause the spring to lower the lid;wherein the actuator housing also includes a plurality of wheels to move the trolley between the top position and the bottom position. 3. The system as set forth in claim 2 and further including stop shoulders to limit rotation of the pedal upon reaching horizontal whereby continued pressure by a foot of a user on the pedal will lower its associated trolley. 4. A dumpster lid opening system (10) for raising and lowering dumpster lids hands free, solely through foot pedals, the raising and lowering being done in a safe, sanitary, convenient and economic manner, the system comprising, in combination; a container (14) having a rectangular horizontal base plate (16) and a rectangular vertical front wall (18) and a rectangular vertical rear wall (20) and parallel, vertical first and second side walls (22), (24), the side walls and the front wall and the rear wall each having an upper edge with the front and rear walls having a height, the rear wall height being greater than the front wall height, the upper edges of the side walls being angled downwardly from the upper edge of the rear wall to the upper edge of the front wall, the walls defining a chamber there between with an open top (26);a first lid (30) and a similarly configured second lid (32), a first hinge (34) located above the rear wall adjacent to the first side wall, the first lid pivotably coupled to the first hinge, a second hinge (36) located above the rear wall adjacent to the second side wall, the second lid pivotably coupled to the second hinge, each lid adapted to be independently pivoted between a lowered closed orientation covering the opening of the container and a raised vertical open orientation above the rear wall;a first pivot bar (40) attached to and associated with the first lid and a second pivot bar (42) attached to and associated with the second lid, each pivot bar being located parallel with and spaced from the side walls, each pivot bar having a long extent (44) attached to the associated lid and a short extent (46) extending upwardly from the long extent at an angle of 30 degrees, plus or minus 10 percent;a first actuator housing (50) secured to the front wall of the housing adjacent to the first lid, a second actuator housing (52) secured to the front wall of the housing adjacent to the second lid, a first trolley (54) in the first actuator housing with four wheels (56) to move the first trolley between a top rest position and a bottom operational position, a second trolley (54) in the second actuator housing with four wheels (56) to move the second trolley between a top rest position and a bottom operational position, first and second springs (58) urging the first and second trolleys upwardly, respectively, first and second pedals (60) coupled to first and second trolleys, respectively, adapted to be depressed by a user against the urging of a tension coil spring (62) move the trolleys to the bottom operational positions, the first and second pedals adapted to be pivoted to a horizontal operative position by a foot of the user, stop shoulders (64), (66) to limit rotation of each pedal upon reaching horizontal whereby continued pressure by the foot of the user on the pedal will lower its associated trolley and stretch its associated spring, a first upper sprocket (68) rotatable in the first housing, a first lower sprocket (70) rotatable in the first housing, a first pulley (72) beneath the rear wall, a second upper sprocket rotatable in the second housing, a second lower sprocket rotatable in the second housing, a second pulley beneath the rear wall; anda first flexible connector (76) having an interior end attached to and associated with the first trolley and having an exterior end attached to the short extent of the first pivot bar, a second flexible connector (78) having an interior end attached to and associated with the second trolley and having an exterior end attached to the short extent of the second pivot bar, each flexible connector being formed as a cable (80) extending from a pivot bar then extending vertically adjacent to the rear wall then around the associated pulley and then horizontal beneath the base plate, each flexible connector including a chain (82) coupling from the associated cable around the associated lower sprocket and then around the associated upper sprocket and then to the associated trolley whereby the depression of the associated pedal will move the associated connector to raise the associated lid while release of the associated pedal will cause the associated spring to lower the associated lid.
