Abstract

Abstract The present invention refers to a transport apparatus in particular for internal, suspension transport systems of the type including a runner rail system and roller sets having rollers interconnected by a depending member. The apparatus has rail-shaped carrier members for supporting, in a suspended condition, transport material on a carrier member support surface. The carrier members are releasably suspendable at both ends from the roller sets, via suspension rods connected to the carrier members at transversely extending pivot axles, and the roller sets rest on the runner rail system. The pivot axles are perpendicularly displaced relative to the longitudinal axis of the carrier member to such an extent that the suspension rods can be folded into contact with a carrier member support surface by pivoting 90°. Clamping grooves are provided on the pivot axles to secure the folded suspension rods. The carrier members include troughs to receive hooks of additional carriers, and toothed racks.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 227 words
A transport means, for a suspension transport system for internal transport, said system being of the type including a runner rail system roller sets resting on said runner rail system, including depending means for interconnecting the rollers in a set, said transport means comprising rail-shaped carrier members each having a longitudinal axis extending from one end to the other end thereof, and a carrier member support surface for supporting goods to be transported in a suspended condition, suspension rods releasably suspending said carrier members from said roller sets, pivot axle means provided at said one end and said other end of said carrier members for pivotally connecting said suspension rods to a carrier member by said pivot axles extending transversely to said carrier member support surface and being perpendicularly displaced relative to said longitudinal axis of said carrier member to such an extent that said suspension rods can be folded into contact with said carrier member support surface by means of pivoting by 90°, and said pivot axles further comprising a clamping groove arranged adjacent to the location of connection of said suspension rods, said clamping groove of a pivot axle arranged at each end of a carrier member for clamping in said contact with said carrier member support surface a suspension rod connected to a pivot axle arranged at the opposite end of said carrier member.
Claim 2
Dependent Claim 227 words
A transport means, for a suspension transport system for internal transport, said system being of the type including a runner rail system roller sets resting on said runner rail system, including depending means for interconnecting the rollers in a set, said transport means comprising rail-shaped carrier members each having a longitudinal axis extending from one end to the other end thereof, and a carrier member support surface for supporting goods to be transported in a suspended condition, suspension rods releasably suspending said carrier members from said roller sets, pivot axle means provided at said one end and said other end of said carrier members for pivotally connecting said suspension rods to a carrier member by said pivot axles extending transversely to said carrier member support surface and being perpendicularly displaced relative to said longitudinal axis of said carrier member to such an extent that said suspension rods can be folded into contact with said carrier member support surface by means of pivoting by 90°, and said pivot axles further comprising a clamping groove arranged adjacent to the location of connection of said suspension rods, said clamping groove of a pivot axle arranged at each end of a carrier member for clamping in said contact with said carrier member support surface a suspension rod connected to a pivot axle arranged at the opposite end of said carrier member.
Claim 3
Dependent Claim 46 words
A transport means according to claim 1, wherein said pivot axle is provided with a tapped hole extending parallel to said clamping groove and said suspension rod has an external thread adapted to engage said tapped hole for connecting said suspension rod to said pivot axle.
Claim 4
Dependent Claim 56 words
A transport means according to claim 1 wherein said pivot axle has a retention hole serving as said clamping groove and said suspension rod has at least one portion adapted to be locked in position in said retention hole, by means of a rotation by approximately 90°, for connecting said suspension rod to said pivot axle.
Claim 5
Dependent Claim 53 words
A transport means according to claim 3 wherein locking projections are provided on said at least one portion of said suspension rod at a point remote from said roller set, and said retention hole is a snap-in hole in which said locking projection can be fixed in the manner of a bayonet catch.
Claim 6
Dependent Claim 59 words
A transport means according to claim 3 wherein said retention hole extends through said pivot axle forming a first and a second opening and is provided at each opening with outlet portions for locking said locking projections when said suspension rod is inserted into said retention hole, either initially from said first opening, or initially from said second opening.
Claim 7
Dependent Claim 29 words
A transport means according to claim 4 wherein said suspension rod contains further locking means arranged between said roller sets and said locking means remote from said roller sets.
Claim 8
Dependent Claim 65 words
A transport means according to claim 1, comprising suspension rods having ends in the form of open hooks facing away from the carrier member, wherein each of said carrier members includes between its pivot axle and said carrier member support surface a transversely extending trough which is used for having an additional carrier member attached thereto by means of the hooks of its suspension rods.
Claim 9
Dependent Claim 45 words
A transport means according to claim 1, wherein each carrier member includes a first toothed rack which extends along at least a portion of said longitudinal axis and facing away from said carrier member support surface, and said first toothed rack having transversely extending indentations.
Claim 10
Dependent Claim 68 words
A transport means according to claim 8, wherein an additional toothed rack is arranged on said carrier member support surface of said carrier member, the width of said additional toothed rack being dimensioned so as to leave enough space at both sides for folding in said suspension rods, and the tooth spaced of said additional toothed rack is different from the tooth spacing of said first toothed rack.
Claim 11
Dependent Claim 26 words
A transport means according to claim 1, wherein said pivot axles are supported between suitable extended portions of sidewalls of the profile of said carrier member.
