Description
Background of the Invention and Prior Art
This invention relates to viewing devices. More particularly, though not exclusively, this invention concerns a viewing device capable of providing a clear picture of objects located behind an observer without the observer having to turn around in order to see these objects.
The invention is especially useful for viewing baby capsules, seats or the like during the driving of vehicles.
It is commonly known that under the law of many countries vehicles must be fitted with approved baby capsules or seats when carrying babies and children under a certain age. Baby capsules and seats are usually fitted to the back seat of the vehicle and undoubtedly are a life saving feature. However, the location of a capsule or seat, though aimed at safety of babies and children, may cause significant apprehension to the driver of the vehicle or car since he or she cannot see the child while driving. In order to see the child, the driver would have to stop the car or, alternatively, turn around while driving. The latter would represent a driving danger and may result in accidents and serious injuries.
The present invention seeks to overcome or at least substantially alleviate this problem and to provide a device which permits the viewing of objects located to the rear of an observer without the observer having to turn around in order to see these objects.
Although the present invention will be described herein in connection with baby capsules and seats, it will be appreciated that the invention may find many different applications.
Summary of the Invention
In one broad form the present invention provides a viewing device adapted to enable an observer in a vehicle to view an object located to the rear of the observer, the vehicle having a rear vision mirror, the device comprising:
a support adapted to be rigidly affixed to the vehicle; and
a reflecting means mounted on the support, the reflecting means capable of cooperating with the rear vision mirror so as to provide an image of the object in the rear vision mirror.
Preferably, the vehicle has a front area and a rear area and the observer is positioned in the front area while the object is positioned in the rear area of the vehicle.
The vehicle may further have a rear window and it is preferred that the support be fixed to the vehicle between the rear window and the rear vision mirror. Conveniently, the support comprises a lamina which is at least partially transparent so that it would not preclude the normal use of the rear vision mirror. The lamina may be manufactured from a plastic material such as clear perspex or the like. Preferably, the support includes an adjusting means to enable it to fit different types of vehicles.
Where the rear area of the vehicle includes a seat with a backrest, the support may in use extend in an upward direction from the backrest.
Where the vehicle has a ceiling and the support in use extends in an upward direction from the backrest to the ceiling, the support may be rigidly attached to the ceiling in a known manner (by fasteners, for example).
Preferably, the reflecting means comprises a mirror mounted on the support. Advantageously, the mirror is positioned on the support in such a way as to reflect the image of the object (which, as mentioned above, may be a baby capsule, seat or the like) in the rear vision mirror. It is preferred that the mirror be adjustable in such a way as to allow the image of the object to be seen in the rear vision mirror by observers of different height.
It should be appreciated that the reflecting means may comprise more than one mirror in situations where there is a plurality of objects to be seen by the observer; for example, a twin capsule, a capsule and seat, etc. In this embodiment, it is preferred that at least one mirror mounted on the support be capable of cooperating with the rear vision mirror so as to provide an image of the plurality of objects in the rear vision mirror.
It should also be appreciated that the vehicle may have more than one rear vision mirror. In this embodiment of the invention, it is preferred that the mirror mounted on the support be capable of cooperating with each rear vision mirror so as to provide an image of the object in each rear vision mirror.
In the embodiment having a plurality of reflecting means mounted on the support and a plurality of rear vision mirrors, it is preferred that each reflecting means be capable of cooperating with at least one rear vision mirror so as to provide an image of one or more of objects in at least said one rear vision mirror.
In situations when additional illumination is required or desirable, the reflecting means may further comprise a light adapted to illuminate the interior of the vehicle in the vicinity of the object so as to allow the image of the object to be seen by the observer at night. Beneficially, the light may be provided with an ON/OFF switch and may have a separate power source or, alternatively, be connected to a vehicle's battery in a known manner via, for example, a cigarette lighter.

Vehicle 40, in which one preferred embodiment of device 10 is installed (see FIG. 2), has ceiling 41, rear vision mirror 42, front area 44 and rear area 46. Rear seat 48 having backrest 49 is positioned in rear area 46.
Support 20 is made from a sheet of clear perspex and comprises horizontal portion 22, inclined portion 24 and tail portion 26. Inclined portion 24 is shown in truncated form to reduce the dimensions of FIG. 1. Horizontal portion 22 is approximately 150 mm long, 500 mm wide and 5 mm thick. Horizontal portion 22 permits support 20 to be rigidly affixed to ceiling 41 by way of screws 21 in a known manner (also see FIGS. 3 and 4). Inclined portion 24, on which reflecting means 30 is mounted, is approximately 600 mm long, 500 mm wide and 5 mm thick. Tail portion 26 of approximately 100 mm length, 500 mm width and 5 mm thickness site on top of backrest 49 of vehicle 40 and is provided with tongue 28 which is permanently affixed to tail portion 26. Tongue 28 is generally an angled plate made of aluminium and serves to assist the correct placement of support 20 inside vehicle 40.
It should be appreciated that the dimensions of portions 22, 24 and 26 and the angle of inclination of portion 24 vary depending on the dimensions and type of the vehicle.
Referring now specifically to FIG. 3, reflecting means 30 comprises mirror 32 and light 34 (both are also shown in FIG. 1). Mirror 32 is mounted on support 20 by any suitable means and is positioned on support 20 in such a way as to reflect an image of object 11 (shown in FIG. 2), which is the baby capsule, seat or the like.
