Abstract

The assembly comprises a housing (1), a mirror (9) rotatably supported in the housing (1), and driving means in the form of a fan (4) within the housing (1) for rotating the mirror (9). Alternatively, the mirror may be stationarily supported in the housing and a rotary wiper is provided for the mirror. Instead of a fan, the driving means may be in the form of an electric motor. The arrangements ensure adequate rear vision in all weather conditions. <IMAGE>

SPECIFICATION Improvements in or relating to vehicle external rear view mirror assemblies
Description This invention relates to vehicle external rear view mirror assemblies.
The object of the invention is to enable a vehicle external rear view mirror assembly to provide a rear view under any weather conditions.
According to one aspect of the invention there is provided a vehicle external rear view mirror assembly comprising a housing, a mirror rotatabiy supported in the housing, and driving means within the housing for rotating the mirror.
Accordng to another aspect of the invention there is provided a vehicle external rear view mirror assembly comprising a housing, a mirror stationarily supported in the housing, a rotary wiper for the mirror, and driving means within the housing for rotating the wiper.
The driving means may be either a fan driven by the vehicle's slipstream or an electric motor.
Embodiments of the invention wiil now be described, by way of example, with reference to the accompanying drawing, in which: Figure 1 is an elevation of a truck external rear view mirror assembly viewed from the side opposite the mirror; Figure 2 is a section through the assembly in Fig. 1; Figure 3 is an elevation of a modified truck external rear view mirror assembly viewed from the mirror side; and Figure 4 is a section through the assembly in Fig. 3.
In Figs. 1 and 2, a mirror assembly comprises a rectangular housing 1. The housing 1 comprises a base plate 2 and a cover 3 enclosing a space occupied by an axial flow fan 4 rotatable with a shaft 5 journalled in the base plate 2. The cover 3 has a circular opening 6 exposing the fan 4 from the front to a slipstream and upper and lower slot openings 7 and 8 for outflow of air. On the end of the shaft 5 opposite the fan 4 is a circular flat mirror disc 9 concentric with the shaft 5. The disc 9 is surrounded by the remainder 10 of a rectangular flat mirror secured to the base plate 2.
As shown in Figs. 3 and 4, the arrangement of the disc 9 and the remainder 10 of the rectangular flat mirror is the same as in Figs.
1 and 2. However, the fan 4 is replaced by a tangential flow fan 11 rotatable with a shaft 12 journalled in a cover 13 and the disc 9 is attached directly to the fan. A tapered inlet 14 to the fan 11 is provided in one side of the cover 13 and an outlet 1 5 is provided at the other side.
The assembly shown in Figs. 1 and 2 is intended for the side of the truck on which the driver sits since the assembly on that side faces more squarely into the slip-stream than on the other side of the truck where the assembly shown in Figs. 3 and 4 is more suitable.
In other variations in the invention the whole mirror may be a circular rotatable disc. Instead of being flat the mirror may be convex. The fan 4 or 11 may be replaced by an electric motor operable from within the vehicle. Instead of a rotary mirror the mirror may be stationary with a rotary wiper driven by a fan or an electric motor.
CLAIMS 1. A vehicle external rear view mirror assembly comprising a housing, a mirror rotatably supported in the housing, and driving means within the housing for rotating the mirror.
2. A vehicle external rear view mirror assembly comprising a housing, a mirror stationarily supported in the housing, a rotary wiper for the mirror, and driving means within the housing for rotating the wiper.
3. An assembly according to claim 1 or 2, wherein the driving means is a fan driven by the vehicle's slipstream.
4. An assembly according to claim 1 or 2, wherein the driving means is an electric motor.
5. A vehicle external rear view mirror assembly substantially as hereinbefore described with reference to Figs. 1 and 2 of the accompanying drawing.
6. A vehicle external rear view mirror assembly substantially as hereinbefore described with reference to Figs. 3 and 4 of the accompanying drawing.
