Abstract
Abstract A mono-rail trolley having a carrying wheel adapted to run along the inside of a substantially C-shaped guide rail comprises mainly a shackle to which the trolley motor and the carrying wheel are mounted. The carrying wheel moves on the inside of the rail behind the lower rim which guide wheels which are also mounted on the shackle, move on the inside of the rail behind an upper rim. In order to facilitate both dismantling of the trolley and its removal from the guide rail the guide wheels are mounted on a carrier plate which in turn is detachably connected to the upper shackle portion. The trolley may thus be easily taken out of the guide rail simply by separating the carrier plate from the shackle. All electrical connections are plug-in connections which may also be disconnected in a simple manner.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
195 words
A trolley for a substantially C-shaped mono-rail having current conducting bars in the upper portion of the rail, the trolley comprising a. a motor, b. a gear mechanism in driving connection with said motor, c. a carrying wheel adapted to support the trolley on the running surface of the mono-rail, said carrying wheel being driven by said gear mechanism, d. a shackle to which said motor, said gear mechanism and said carrying wheel are mounted for forming a subassembly which may be separately handled, e. a carrier plate detachably mounted on the upper portion of said shackle, and f. current conducting means for transmitting the current from the current conducting bars by way of plug-in connections to the motor and to further electric components, said current conducting means and said plug-in connections being part of said carrier plate; the trolley being safely retained in said mono-rail when said carrier plate is mounted on said upper shackle portion and being easily removable from said mono-rail when said carrier plate is detached from said upper shackle portion and said plug-in connections are disconnected so that said shackle and said carrier plate may be handled as separate units.
Claim 2
Dependent Claim
195 words
A trolley for a substantially C-shaped mono-rail having current conducting bars in the upper portion of the rail, the trolley comprising a. a motor, b. a gear mechanism in driving connection with said motor, c. a carrying wheel adapted to support the trolley on the running surface of the mono-rail, said carrying wheel being driven by said gear mechanism, d. a shackle to which said motor, said gear mechanism and said carrying wheel are mounted for forming a subassembly which may be separately handled, e. a carrier plate detachably mounted on the upper portion of said shackle, and f. current conducting means for transmitting the current from the current conducting bars by way of plug-in connections to the motor and to further electric components, said current conducting means and said plug-in connections being part of said carrier plate; the trolley being safely retained in said mono-rail when said carrier plate is mounted on said upper shackle portion and being easily removable from said mono-rail when said carrier plate is detached from said upper shackle portion and said plug-in connections are disconnected so that said shackle and said carrier plate may be handled as separate units.
Claim 3
Dependent Claim
56 words
A trolley for a substantially C-shaped mono-rail aS claimed in claim 1, and further comprising guide wheels mounted for rotation in a horizontal axis on said carrier plate, said guide wheels being adapted to contact the inner surface in the upper portion of the mono-rail, thereby providing a guidance for the trolley in a vertical plane.
Claim 4
Dependent Claim
28 words
A trolley for a substantially C-shaped mono-rail as claimed in claim 1, and further comprising a box for switches and electric control elements attached to said carrier plate.
Claim 5
Dependent Claim
84 words
A trolley for a substantially C-shaped mono-rail as claimed in claim 1, and further comprising a girder hinged on said shackle for transporting goods by the trolley; a trigger lever being pivotably attached to said girder and being connected by a Bowden cable to a stop switch in the motor circuit; said trigger lever being adapted to contact other goods in the path of the trolley and to switch off said motor if an undue accumulation of goods should occur in said trolley path.
Claim 6
Dependent Claim
197 words
A trolley for a substantially C-shaped mono-rail having the current conducting bars in the upper portion of the rail, the trolley comprising a. a motor, b. a carrying wheel adapted to support the trolley on the running surface of the mono-rail, said carrying wheel being driven by said motor through a belt, c. a girder for supporting the goods to be transported, d. a shackle to which said carrying wheel and said girder are mounted for forming a subassembly which may be separately handled, e. a carrier plate detachably mounted on the upper portion of said shackle, and f. current conducting means for transmitting the current from the current conducting bars by way of plug-in connections to the motor and to further electric components, said motor, said current conducting means and said plug-in connections being part of said carrier plate; the trolley being safely retained in said mono-rail when said carrier plate is mounted on said upper shackle portion and being easily removable from said mono-rail when said carrier plate is detached from said upper shackle portion and said plug-in connections are disconnected so that said shackle and said carrier plate may be handled as separate units.
Claim 7
Dependent Claim
197 words
A trolley for a substantially C-shaped mono-rail having the current conducting bars in the upper portion of the rail, the trolley comprising a. a motor, b. a carrying wheel adapted to support the trolley on the running surface of the mono-rail, said carrying wheel being driven by said motor through a belt, c. a girder for supporting the goods to be transported, d. a shackle to which said carrying wheel and said girder are mounted for forming a subassembly which may be separately handled, e. a carrier plate detachably mounted on the upper portion of said shackle, and f. current conducting means for transmitting the current from the current conducting bars by way of plug-in connections to the motor and to further electric components, said motor, said current conducting means and said plug-in connections being part of said carrier plate; the trolley being safely retained in said mono-rail when said carrier plate is mounted on said upper shackle portion and being easily removable from said mono-rail when said carrier plate is detached from said upper shackle portion and said plug-in connections are disconnected so that said shackle and said carrier plate may be handled as separate units.
Claim 8
Dependent Claim
28 words
A trolley for a substantially C-shaped mono-rail as claimed in claim 5, wherein the detachable connection between said upper shackle portion and said carrier plate is a dovetail-connection.
Claim 9
Dependent Claim
34 words
A trolley for a substantially C-shaped mono-rail as claimed in claim 5, and further comprising a tension spring inserted between said upper shackle portion and said carrier plate for establishing an appropriate belt tension.
Claim 10
Dependent Claim
37 words
A trolley for a substantially C-shaped mono-rail as claimed in claim 5, wherein electric components are attached to said girder and an electric connection is established between said components and said carrier plate by cables and plugs.
