Abstract
Abstract Transportation apparatus for transporting persons between spaced landings, including a conveyor mounted on a support structure, and a balustrade formed of a plurality of panels aligned in end-to-end relation. An endless handrail is guided over the top edge of the balustrade via a handrail guide member which extends to and partially defines newel sections at opposite ends of the transportation apparatus. Support channels extend from newel to newel to support the lower edge of the balustrade. Structural members complete the newels, extending from the opposite ends of the support channel to the ends of the handrail guide member. The structural members are tapered to provide a stepless transition from the handrail guide members, which are relatively thin, to the larger dimension of the support channel. Support for the structural members, which are cantilevered outwardly from the support structure, is provided by a splice-clamp arrangement which provides excellent support and lateral stability.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
417 words
Transportation apparatus for transporting persons between spaced landings, comprising: a support structure, a load bearing conveyor mounted on said support structure, a balustrade, means mounting said balustrade on said support structure, said balustrade including a plurality of vertically oriented panel members aligned in abutting end-to-end relation to define substantially continuous upper and lower edge portions which terminate in first and second newel sections, a handrail, handrail guide means for said handrail, said handrail guide means including a guide member supported by said upper edge portion which extends to and partially defines said first and second newel sections, said guide member extending inwardly from said upper edge portion for a predetermined first dimension, said means mounting the balustrade on said support structure including a support channel and first and second structural members, said support channel extending inwardly from said lower edge portion for a predetermined second dimension which is greater than said first dimension, said first and second structural members each having first and second ends, and a substantially U-shaped recess which extends between said first and second ends, each of said first and second structural members having a straight portion adjacent its first end, and a curved portion adjacent its second end, said first and second structural members being disposed with their first ends substantially abutting opposite ends of said support channel and their second ends substantially abutting opposite ends of said guide member with their curved portions cooperating with said guide member in defining said first and second newel sections, the U-shaped recess adjacent the first end of each of said first and second structural members extending inwardly to a depth equal to said second dimension, with the depth of the recess being gradually reduced in the curved portion such that the depth of the recess is equal to said first dimension at the second end, to provide stepless transitional support for said panel members at each of said first and second newel sections between said guide member and said support channel, with the panel members which start at the first and second newel sections extending beyond the abutting ends of the associated structural member and support channel, and first and second clamping means on said support structure which connect the first ends of said first and second structural members, respectively, to said support channel, and allow the second ends of the first and second structural members to be cantilevered outwardly from said support structure while providing lateral stability in said first and second newel sections.
Claim 2
Dependent Claim
417 words
Transportation apparatus for transporting persons between spaced landings, comprising: a support structure, a load bearing conveyor mounted on said support structure, a balustrade, means mounting said balustrade on said support structure, said balustrade including a plurality of vertically oriented panel members aligned in abutting end-to-end relation to define substantially continuous upper and lower edge portions which terminate in first and second newel sections, a handrail, handrail guide means for said handrail, said handrail guide means including a guide member supported by said upper edge portion which extends to and partially defines said first and second newel sections, said guide member extending inwardly from said upper edge portion for a predetermined first dimension, said means mounting the balustrade on said support structure including a support channel and first and second structural members, said support channel extending inwardly from said lower edge portion for a predetermined second dimension which is greater than said first dimension, said first and second structural members each having first and second ends, and a substantially U-shaped recess which extends between said first and second ends, each of said first and second structural members having a straight portion adjacent its first end, and a curved portion adjacent its second end, said first and second structural members being disposed with their first ends substantially abutting opposite ends of said support channel and their second ends substantially abutting opposite ends of said guide member with their curved portions cooperating with said guide member in defining said first and second newel sections, the U-shaped recess adjacent the first end of each of said first and second structural members extending inwardly to a depth equal to said second dimension, with the depth of the recess being gradually reduced in the curved portion such that the depth of the recess is equal to said first dimension at the second end, to provide stepless transitional support for said panel members at each of said first and second newel sections between said guide member and said support channel, with the panel members which start at the first and second newel sections extending beyond the abutting ends of the associated structural member and support channel, and first and second clamping means on said support structure which connect the first ends of said first and second structural members, respectively, to said support channel, and allow the second ends of the first and second structural members to be cantilevered outwardly from said support structure while providing lateral stability in said first and second newel sections.
Claim 3
Dependent Claim
67 words
The transportation apparatus of claim 1 wherein each of the first and second clamping means includes a splice member fastened to the adjacent ends of the structural member and support channel, and a clamp assembly which clamps the splice member and the adjoining ends of the structural member and support channel firmly between spaced members of the clamp assembly to provide lateral support for the newel sections.
Claim 4
Dependent Claim
45 words
The transportation apparatus of claim 2 wherein the splice member is connected between an end of the support channel and the first end of one of the first and second structural members, and the clamp assembly is disposed to apply pressure to the splice member.
Claim 5
Dependent Claim
12 words
The transportation apparatus of claim 1 wherein the panel members are transparent.
Claim 6
Dependent Claim
12 words
The transportation apparatus of claim 1 wherein the panel members are glass.
Claim 7
Dependent Claim
90 words
The transportation apparatus of claim 1 wherein each of the first and second clamping means includes a splice member connected between an end of the support channel and the first end of one of the first and second structural members, with said splice member being connected to one of the sides of the support channel which defines the second dimension, and a clamp assembly for supporting and clamping the adjacent ends of the support channel and one of the structural members, with said clamp assembly also clamping said splice member.
Claim 8
Dependent Claim
20 words
The transportation apparatus of claim 6 wherein the clamp assembly includes a plurality of screws which provide the clamp pressure.
Claim 9
Dependent Claim
33 words
The transportation apparatus of claim 6 including pressure distributing means disposed between the sides of the balustrade and the sides of the support channel, at each of the first and second clamping means.
