Abstract
Abstract In a switch, a straight rail section (3) is movable with respect to a stationary rail (1). The straight rail section (3) is connected via a bracket (5) to a movable switch base plate (6) which is guided by travel wheels (7) in travel or running rails (12) and by guide rollers (8) in guide rails (13) of lateral profiled sections (9). The lateral profiled sections are connected to each other by intermediate profiled sections (11) forming a support plate (10).

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
122 words
A guide and support track system comprising: a stationary rail section; a movable rail section; a base plate (6) carrying said movable rail section and movable between a first position in which said movable rail section is aligned with said stationary rail section and a second position in which said movable rail section is displaced out of alignment with said stationary rail section; a lateral profiled section (9) forming a stationary running rail and a guide rail for guiding said base plate between said first and second positions; and an intermediate profiled section (11), said lateral and intermediate profiled sections having mutually engageable protrusions (11a) and recesses (11c) for connecting said lateral and intermediate sections to form a stationary support plate (10).
Claim 2
Dependent Claim
122 words
A guide and support track system comprising: a stationary rail section; a movable rail section; a base plate (6) carrying said movable rail section and movable between a first position in which said movable rail section is aligned with said stationary rail section and a second position in which said movable rail section is displaced out of alignment with said stationary rail section; a lateral profiled section (9) forming a stationary running rail and a guide rail for guiding said base plate between said first and second positions; and an intermediate profiled section (11), said lateral and intermediate profiled sections having mutually engageable protrusions (11a) and recesses (11c) for connecting said lateral and intermediate sections to form a stationary support plate (10).
Claim 3
Dependent Claim
40 words
The system of claim 1, further comprising a support structure (16); fastening members (15); and insertion grooves (14) defined in said lateral profiled section (9) for mounting said profiled section with said fastening members (15) to said support structure (16).
Claim 4
Dependent Claim
81 words
The system of claim 1, wherein the stationary support plate (10) comprises a plurality of intermediate profiled sections (11), said intermediate profiled sections being formed by flat rectangular hollow sections connected to each other and to said lateral profiled section by respective opposing protrusions (11a) projecting at an angle from opposed extensions of the lateral and intermediate sections toward the inside thereof for mating engagement with opposed recesses (11c) provided in lateral webs (11b) projecting from said intermediate and lateral sections.
Claim 5
Dependent Claim
38 words
The system of claim 2, further comprising claws (18) for guiding said fastening members (15) inserted into said grooves (14, 14a) of said lateral profiled section; and flanges (17) on said support structure (16) for supporting said claws.
Claim 6
Dependent Claim
28 words
The system of claim 4, further comprising toothed guide plates (19) for guiding said fastening members (15); said guide plates being longitudinally displaceable with respect to each other.
Claim 7
Dependent Claim
45 words
The system of claim 1, further comprising travel wheels (7) and guide rollers (8) on said base plate and movably engaging said running rail and said guide rail; and brackets (5) on said base plate for securing said movable rail section to said base plate.
Claim 8
Dependent Claim
82 words
The system of claim 1, wherein said movable rail section is a straight rail section, and the system further comprising: a movable curved rail section (4) carried on said base plate (6); and brackets (5), and having a bracket foot (5c) at one end thereof for mounting said bracket to said base plate and a support plate (5a) at the other end thereof for lateral attachment to the longitudinal center of said respective straight rail section (3) and curved rail section (4).
Claim 9
Dependent Claim
36 words
The system of claim 7, wherein said bracket foot (5c) further comprises a slot (5b) having the shape of a circular segment for attachment of said bracket to said base plate by an attachment bolt (25).
Claim 10
Dependent Claim
44 words
The system of claim 7, additionally comprising a resting surface (1a) at the end of said stationary rail section (1); and support surfaces (3a, 4a) at the ends of the movable rail sections (3, 4) for aligned engagement with said stationary rail resting surfaces.
Claim 11
Dependent Claim
23 words
The system of claim 1, additionally comprising a motor and gearing operable for moving said base plate between said first and second positions.
Claim 12
Dependent Claim
22 words
The system of claim 1, further comprising a hand crank operable for moving said base plate between said first and second positions.
Claim 13
Dependent Claim
31 words
The system of claim 10, additionally comprising a cut-off switch; and a lever operatively connected to said gearing for actuating said cut-off switch thereby controlling the movement of said base plate.
Claim 14
Dependent Claim
46 words
The system of claim 1, wherein the lateral profiled section (9) is arranged horizontally and the base plate (6) extends in a vertical direction, and additionally comprising a horizontal support plate (6a) connected to the base plate and movable therewith for supporting goods to be transported.
Claim 15
Dependent Claim
26 words
The system of claim 1, wherein the lateral profiled section (9) is arranged vertically and the movable rail section (3) is mounted to said base plate.
Claim 16
Dependent Claim
23 words
The system of claim 1, additionally comprising a protective plate (22) mounted to the lateral profiled section (9) opposite said support plate (10).
