Technical Data
Head Channel shall measure 33mm wide and
30mm deep with a nominal wall thickness of 1.2mm to 1.4mm, extruded from 6063-T5 aluminium
alloy finished in clear anodising to a thickness of 10 microns, or powder coated to a film
thickness of 30 to 40 microns.
Spline Shaft shall be a tri-lobular
aluminium extrusion of 6063-T5 alloy.
Slat Travellers assembly shall be moulded
in a high engineering grade plastic, acetal co-polymer or equivalent and shall incorporate
a worm gear clutch designed to prevent damage to the assembly when overloaded, and to
assist in slat hook synchronisation.UV stabilised slat hook shall be supported on mating
cam faces of a worm wheel to allow self-alignment of slats by a gravity centering
mechanism. slat hooks shall be removable to allow replacement where required without
dismantling the track system.
Slat Spacer Links shall be press-formed
from 0.2mm x 8mm stainless steel (Din 17224) and shall couple the slat travellers together
in a pre-determined spaced relationship and to allow variable lengths to be manufactured
with equal overlap (minimum 12mm) between slats across the width of the shade.
Tilt Control shall be by means of 2mm
diameter braided nylon cord with 4.5mm diameter acetal balls moulded co-axially to it on
11.8mm centres by pulling on a ballchain connected to a pulley.
Slats shall be 89,100 or 127mm wide as
appropriate, and made of crowned prepainted aluminium, flat and shaped adgebeaded PVC, or
plasticised woven and non-woven fabrics. PVC slats shall be provided with centrally
located keyhole shaped apertures which shall be connected by a continuous 2.2mm diameter
stainless steel ballchain. Aluminium slats shall be provided with moulded acetal chain
connectors located centrally in rectangular apertures in the slats and connected by 2.2mm
diameter stainless steel ballchains.
Fabric Slats shall be provided with bottom
pockets housing slat weights which are coupled together by means of endless bead chains
pivotally attached by clasps to each side of each weight. The clasp shall be capable of
self-release from the bottom weight when the chain is subjected to accidental loads.
Bottom Linkage shall couple adjacent slats
at the base to minimise differential movement of slats.
Channel Mounting Brackets shall be press
formed angle brackets ribbed for stiffness and provided with holes for fixing screws and
slotted holes for screw and nut attachment of the channel mounting clips. Finish shall be
clear passivated zinc plate.
Bottom Weight shall be of moulded PVC
compound incorporating an insert filler of high specific gravity. Integrally moulded posts
supported both top and bottom shall be provided to enable pivotal attachment of a
bottom linkage chain at each side of the weight. All parts of the weight shall be of a
smooth finish to facilitate assembly into the bottom pockets of a fabric slat.
Traversing Cord shall be 2.0mm diameter
and constructed with a braided polyester jacket over a polyester core. The cord shall be
held in tension by a cord weight.
Slat Carriers shall be of moulded nylon
and shall be suitable for snap insertion into the hook of the traveller assembly.
Shaft Support shall be used as required to
prevent the spline shaft sagging. multiple support will be activated by the pullcord
traveller by way of magnets in the shaft support. |
