Vehicle emergency sign
BACKGROUND OF THE INVENTION 
     This invention relates to a portable sign for use in motor vehicles, particularly as an emergency distress sign which can be mounted easily and securely on the vehicle window. 
     Such vehicle signs are known but generally these prove cumbersome to store and to install due to a large number of parts both in the mounting system and in display pieces. Other signs of this nature in an attempt to be more convenient and storable have compromised greatly on size and hence on visibility and usefulness. 
     It is, therefore, an object of the present invention to provide a portable sign for use on motor vehicles which is readily legible to passing motorists. 
     A further object of the invention is to provide a sign which is compact and easily stored in a glove compartment or equally small storage space. 
     A further object of the invention is to provide a sign which is easy to mount securely on a side window without the necessity of leaving the vehicle. 
     Still another object of the invention is to provide a sign of simple construction which is inexpensive to manufacture. 
     SUMMARY OF THE INVENTION 
     Accordingly the present, invention provides an extendable sign for mounting on the side of a motor vehicle. The sign has a plurality of extendably interconnected panels of substantially rigid material and a bracket secured to a first panel for mounting the sign to project from the side of the vehicle.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring now more specifically to the details of the invention, the sign 10 comprises in combination a mounting bracket 14, which secures a first panel 16 between the pair of flanges 18 on the bracket 14 at right angles to the bracket portion. A leading edge 4 of the first panel 16 forms an angle such that when joined to the bracket 14 the slope coordinates with that of the vehicle side window allowing the sign to be supported in a relatively horizontal position in use and be easily visible to passing motorists. 
     The first panel is attached to a number of intermediate panels 22 and 23 (in this case two) by attachment means 20 of metal or plastic material, in the present embodiment the panels 16, 22, 23 and 30 are attached with metal rivets 20 carrying plastic washers 21. The intermediate panels 22 and 23 are substantially identical having apertures 19 to receive the attachment means and cut with horizontally extending parallel slots 26. The attachment means extend through the apertures 19 of one panel 22 and through the slots 26 of the next panel 23 and in conventional peg and slot configuration permitting each panel to slide the length of the slots thereby extending or retracting the sign 10. 
     The last panel 30 has slots 26 identical to those on the intermediate panels 22 and 23 however panel 30 does not have apertures 19 to receive rivets. 
     The bracket 14 has an upper hook portion 36 formed to receive the top edge of a vehicle side window 46. When the sign 10 is installed the window 46 can be returned to a closed position tightly securing the sign 10 between the window and frame without causing damage to the vehicle. Bracket 14 has a lower support portion. The bracket is comprised of two cooperating parts--which are reverse images of each other. In an alternate embodiment as shown in FIG. 4 the bracket is moulded as a single piece of suitable plastic material such as styrene, the two portions being connected at the top of the flanges 18 forming a channel to receive the first panel 16. 
     The bracket 14 and sign panels 16, 22, 23 and 30 are made of a durable all-weather plastic such as styrene that will resist breaking in rain, snow or wind. A visible indicia as a message or emblem can be silkscreened or applied to both sides of the sign 10 in high visibility, high contrast or reflective lettering. 
     Alternatively as shown in FIG. 6 panels 16, 22 and 23 are provided with integral moulded fastening means 40 in place of apertures 19 described above for receiving rivet type fastening means 20. 
     The fastening means 40 includes two barbed projections 42 and 44 disposed perpendicularly to the panel 22 so as to cooperate with the slot 26 of the associated panel 23. A third barbed projection 48 is disposed between the projections 42 and 44 and is inverted so as to engage the other side of slot 26. 
     In use the sign 10 hooks on any vertically moveable vehicle side window 46 and is supported in a substantially horizontal position projecting from the side of the vehicle. The sign 10 can be installed from inside the car when the window 46 is partially open. When fully extended in this position the sign 10 is easily visible to passing motorists. The sign 10 retracts to a size convenient for storage in a glove compartment or similar small area.
