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 dolly has a carrying frame (1) provided with a scoop (2) which is coupled to an end of said frame in such a way that it can pivot about a pivoting axis (3). The scoop is movably coupled, by a control mechanism, to two wheel carriers which can be respectively pivoted about a bearing axis extending transversally in relation to the pivoting axis (3) of the scoop and which carry running wheels (4), in such a way that when the scoop is pivoted, the wheel carriers pivot out of a storage position oriented parallel to the carrying frame (1), into a use position which is perpendicular to the frame and in which the wheel carriers are oriented parallel to each other. The dolly is provided with an actuating handle (6) which can be pivoted about an axis parallel to the scoop axis (3) and which is movably coupled to the scoop (2) by a connecting rod (7). When the handle (6) is pivoted from an idle position into an intermediate position, the wheel carriers (5) pivot out of their storage position into their position of use, and when the handle (6) is further pivoted into an end position in which it (6) fixes the two wheel carriers (5) in a pivoting manner, a clamping force is exerted on the connecting rod (7).

The invention claimed is: 1. A dolly, comprising: a carrying frame, at one end of which is articulated a scoop configured to be pivoted about a pivot axis and is coupled for movement, via a gear mechanism, to two wheel carriers, each configured to be pivoted about a bearing axis extending transversely to the pivot axis of the scoop and carry running wheels, such that, during pivoting of the scoop, the wheel carriers are pivotable between: (i) a storage position, in which the wheel carriers are oriented parallel to the carrying frame; and (ii) a use position in which the wheel carriers are oriented perpendicular to the carrying frame and parallel to one another; an actuating handle configured to be pivoted about a handle axis extending parallel to the scoop axis, the handle engaging the two wheel carriers in the use position; and a connecting rod coupling the handle to the scoop. 2. The dolly of claim 1, further comprising a lever coupled to the connecting rod and including a plurality of arms, the arms configured to fix the wheel carriers against pivoting in the use position. 3. The dolly of claim 1, wherein when the handle is displaced from an intermediate position into an end position, the connecting rod is displaced over a dead center. 4. The dolly of claim 3, wherein the dead center corresponds to a handle pivoting position in which the handle is positioned outside a pivoting space of the running wheels. 5. The dolly of claim 1, wherein the connecting rod is elastic. 6. The dolly of claim 1, further comprising a lever coupled to the carrying frame by an elastic mounting element. 7. The dolly of claim 1, wherein the handle includes a plurality of latching elements and each of the wheel carriers includes a latching pocket, the latching elements configured to engage the latching pockets. 8. The dolly of claim 1, wherein the handle includes a plurality of collars and each of the wheel carriers includes an opening, the collars configured to engage the openings. 9. The dolly of claim 1, further comprising a lever coupled to the handle, the lever comprising a plastic material. 10. The dolly of claim 9, wherein the lever includes a groove, the connecting rod engaging the groove in the use position. 11. The dolly of claim 1, further comprising a first coupler coupling at least one of the wheel carriers to the scoop, the first coupler including radial teeth. 12. The dolly claim 1, further comprising a lever coupled to the carrying frame by a bearing, the lever further coupled to the handle. 13. The dolly of claim 1, further comprising an adjustable handgrip coupled to the carrying frame, the handgrip positioned at a first end of the carrying frame, the scoop positioned at a second end of the carrying frame. 14. The dolly of claim 13, wherein the handgrip is configured to telescopically extend from the carrying frame. 15. The dolly of claim 1, wherein the carrying frame includes a first portion and a second portion, and further comprising a crossmember coupled to the first portion and the second portion. 16.
