Sighting device for a vehicle

DETAILED DESCRIPTION OF THE INVENTION In the accompanying drawings which form a part of the specification and are to be read in conjunction therewith, and in which like reference numerals are employed to indicate like parts in the various views: FIG.
1 is a perspective view illustrating a device constructed in accordance with the invention shown mounted on the dashboard of a vehicle positioned to assist in the accurate driving of the vehicle along a road; FIG.
2 is a perspective view on an enlarged scale of the sighting device shown in FIG.
1 detached from the dash-board; FIG.
3 is a side elevational view on an enlarged scale of the sighting device shown in FIG.
1 mounted on a fragment of the dashboard with the telescopic arm member retracted from the positions shown in FIGS.
1 and 2, the broken lines indicating pivotal movement of the sight board and the arm member; and FIG.
4 is a fragmentary front elevational view on a still larger scale illustrating the connection of the arm member to the swivel connection, the broken lines indicating pivotal movement of the swivel connection and arm member.
Referring now to the drawing in detail, numeral 10 generally designates a sighting device constructed according to a preferred embodiment of the invention.
With reference to FIGS.
2 and 3, the sighting device 10 includes a short cylindrical mounting member 11 which is adapted to be mounted to a dashboard 12 within the driver's compartment of a vehicle.
Member 11 is threaded for approximately one half of its length on one end in order to receive a nut 13 which is used to secure it to dashboard 12.
A swivel connection 14 is mounted on the end of member 11 opposite the threaded end.
A central cylindrical portion 15 of member 11 is located between the threads and swivel connection 14.
Portion 15 is slightly larger in diameter than the threaded area of member 11 and is smaller in diameter than the swivel connection.
Swivel connection 14 is generally tubular and is secured over the end of member 11 in a manner that permits it to rotate about the axis of member 11 through at least 180
