Abstract
Abstract A transportation installation incorporating a horizontal and/or vertical and/or inclined extending track rail equipped with at least one rail member, along which there can travel a number of transportation or conveying units having a drive means and devices for receiving loads. The track rail possesses branching points equipped with switch or routing means. The switch or routing means incorporates a movable portion embodying linear and/or curved connection rail pieces for the track rail which, with respect to their position and their rail surfaces as well as also their planes perpendicular to such rail surfaces and containing the rail axes deviate from one another.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
176 words
A transportation installation of the type comprising selectively any one of a number of either horizontally, vertically or inclined extending track rail means, or combinations thereof, said track rail means having track surfaces and embodying a plurality of rail members along which there is adapted to travel a number of transport units having drive means and means for receiving a load, junction points having switch means provided for said track rail means, said switch means including movable means incorporating connection rail means having track surfaces and provided for said track rail means, said connection rail means deviating from one another with respect to their position, said connection rail means likewise having their track surfaces deviating from one another, each connection rail means including support means for said track surface, said support means incorporating a second surface, and further wherein each second surface incorporates a respective plane taken perpendicular to the associated track surface and parallel to the associated track axis of each associated connection rail means and said planes also deviate with respect to one another.
Claim 2
Dependent Claim
176 words
A transportation installation of the type comprising selectively any one of a number of either horizontally, vertically or inclined extending track rail means, or combinations thereof, said track rail means having track surfaces and embodying a plurality of rail members along which there is adapted to travel a number of transport units having drive means and means for receiving a load, junction points having switch means provided for said track rail means, said switch means including movable means incorporating connection rail means having track surfaces and provided for said track rail means, said connection rail means deviating from one another with respect to their position, said connection rail means likewise having their track surfaces deviating from one another, each connection rail means including support means for said track surface, said support means incorporating a second surface, and further wherein each second surface incorporates a respective plane taken perpendicular to the associated track surface and parallel to the associated track axis of each associated connection rail means and said planes also deviate with respect to one another.
Claim 3
Dependent Claim
36 words
A transportation installation as defined in claim 1, wherein said respective planes containing said track axes perpendicular to said track surfaces of said connection rail means of said track rail means intersect along a predetermined axis.
Claim 4
Dependent Claim
88 words
A transportation installation as defined in claim 1, wherein said respective planes containing said track axes are perpendicular to said track surfaces of said track rail means, and wherein the line of intersection of said respective planes forms a pivot axis for said movable means of said switch means so that the individual connection rail means of said track rail means can be selectively pivoted about said pivot axis in order to be placed into a throughpassage position for the transport units or out of such throughpassage position.
Claim 5
Dependent Claim
44 words
A transportation installation as defined in claim 1, further including means defining a pivot axis for said movable means of said switch means, said pivot axis being located outside of said respective planes containing said track axes which are perpendicular to said track surfaces.
Claim 6
Dependent Claim
30 words
A transportation installation as defined in claim 1, wherein said respective planes which are perpendicular to said track surfaces and containing said track axes extend substantially parallel to one another.
Claim 7
Dependent Claim
36 words
A transportation installation as defined in claim 5, further including means for slideably displacing said connection rail means of said track rail means into a throughpassage position or out of the latter for said transport units.
Claim 8
Dependent Claim
62 words
A transportation installation as defined in claim 5, further including means cooperating with said connection rail means for rotating said connection rail means selectively into and out of an operational position about an axis of rotation disposed between said connection rail means and parallel to said planes containing said track axes and perpendicular to the track surfaces of said connection rail means.
Claim 9
Dependent Claim
37 words
A transportation installation as defined in claim 1, whereIn said connection rail means comprise two connection rail members, and means for pivotably mounting said two connection rail members through a pivot angle which is less than 90*.
Claim 10
Dependent Claim
36 words
A transportation installation as defined in claim 1, wherein said connection rail means comprises three connection rail members, and means for pivotably mounting said three connection rail members through an angle which is less than 180*.
Claim 11
Dependent Claim
53 words
A transportation installation as defined in claim 1, wherein the confronting region between said track rail means and said connection rail means defines a rail joint, and means provided for said rail joint defining a groove-resilient connection arrangement for the purpose of retaining together said rail joint upon passage therethrough of a load.
Claim 12
Dependent Claim
46 words
A transportation installation as defined in claim 1, wherein the confronting region of said track rail means and said connection rail means of said movable means of said switch means defines a rail joint, and locking means ensuring for the lateral alignment of said rail joint.
Claim 13
Dependent Claim
40 words
A transportation installation as defined in claim 1, wherein the confronting region between said connection rail means and the neighboring track rail means defines a rail joint, and fixed stop means ensuring for the lateral alignment of said rail joint.
