Abstract

An additional sun visor is clamped to a vehicle sun visor by means of fixing which allow the additional visor to rotate and fold back when not required. <IMAGE>

Description

SPECIFICATION Vehicle visor add visor Components: 1/ Anti-glare vision screen incorporating a excentric integral lug to each side, with a hole in each lug to receive a self tapping screw passing through, when driven. The screen is moulded in semi rigid translucent plastic capable of production in varying unit colour tints and varying degrees of density of colour.

2/ Two semi rigid plastic jaw clamps with flexible expanding jaws, with a hole in each to allow self tapping screw to pass through with slide tolerance.

3/ Two plastic washers.

4/ Two stainless steel (or sherardised) self tapping screws with unthreaded length of shank at head end equal to the thickness of the fixing lugs.

Function of the visor add-visor To ease eye strain in bright daylight and reduce near direction light glare encountered by vehicle driver and/or front seat passenger when the vehicle is moving facing into the sun in early morning of late evening, when the angle of the sun is below the lower edge of the sun visor provided in the vehicle at its maximum functional setting.

Operational function Set below the lower edge of the vehicle sun visor, when it is in the down (functional) position. When fitted to the existing sun visor the assembly is held in location by the frictional grip of the jaw clamps onto the vehicle sun visor.

The angle of the visor add-visor is variable in relation to the vehicle sun visor.

This facility is afforded by the frictional interfaces of the excentric lugs on the addvisor sceeen, and the adjacent face of the jaw clamps the degree of friction is determined by the tightening of the self tapping assembly screws. The frictional coefficient is variable and the connections can be adjusted for wear if required.

Mode of operation When not in use the visor add-visor is folded back to lay flat against the top face of the vehicles existing sun visor, when it is in the up (out of use) position.

The vehicle sun visor may be used for its prime function at any time, with the visor addvisor folded back in the out of use position.

When the visor add-visor is required it is gyrated down below the lower edge of the vehicle sun visor as an anti glare vision screen, and through the agency of the frictional interfaces of the visor lugs and the jaw clamps, may be set to any desired angle relative to the predetermined set angle of the vehicle sun visor.

The visor add-visor and the associated jaw clamps are for manufacture by plastic injection moulding.

Marketing by boxed components through motorist shops and garages, for "do it yourself" assembly, coupled with assembly instruction sheet.

CLAIMS Vehicle visor add visor 1. A mountable/demountable assembly consisting of a flat, translucent, semi-rigid, plastic, anti glare, through vision screen for fitting to the sun visor provided on vehicles.

The screen is nominally rectangular with shaped corners, and fixing means for securing the screen to vehicles existing sun visor through the agency of secondary connectors and washers and fixings which allow the vision screen to rotate, and fold back when not required, through a controlable frictional interface, about a part threaded fulcrum fixing at each side of the assembly, which fulcrum fixing is adjustable, and complementary to the vision screen and the secondary connectors.

2. A mountable/demountable assembly as claimed in claim 1, wherein a fixing lug is provided to each side of the through vision screen adjacent to the fulcrum top edge with each lug set excentric to a face of the vision screen.

3. A mountable/demountable assembly as claimed in claim 2 wherein a hole is provided through each excentric fixing lug to accommodate a connection fulcrum fixing pivot.

4. A mountable/demountable assembly as claimed in claim 1, wherein anti glare potential in the vision screen is induced through the agency of translucent colour density incorporated into the plastic moulding of the vision screen.

5. A mountable/demountable assembly as claimed in claim 1 wherein the fixing means to a vehicle sun visor is through the agency of semi-rigid connectors fixed to the vision screen adjacent to the fixing lugs on the
