Description
Background of the Invention
1. Field of the Invention
The instant invention relates generally to directional signal switches and more specifically it relates to a lane changer apparatus.
2. Description of the Prior Art
Numerous directional signal switches have been provided in prior art that are adapted to indicate which way motor vehicles are turning by illuminating right or left turn signal lights operated by activating levers in the motor vehicles. While these units may be suitable for the particular purpose to which they address, they would not be as suitable for the purposes of the present invention as heretofore described.
Summary of the Invention
A primary object of the present invention is to provide a lane changer apparatus that will overcome the shortcomings of the prior art devices.
Another object is to provide a lane changer apparatus in which the directional signal switch in a steering column in a motor vehicle is replaced by left and right lane change signal button switches mounted on the steering wheel.
An additional object is to provide a lane changer apparatus in which the two lane change signal button switches are easily accessible to the right and left thumbs of the driver of the motor vehicle, so that the eyes of the driver will be free to look quickly into all mirrors to see if any other motor vehicles are nearby when changing lanes.
A further object is to provide a lane changer apparatus that is simple and easy to use.
A still further object is to provide a lane changer apparatus that is economical in cost to manufacture.
Further objects of the invention will appear as the description proceeds.
To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.

Detailed Description of the Preferred Embodiments
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1 through 6 illustrates a lane changer apparatus 10 in a motor vehicle 12 comprising a structure 14 built into a steering wheel 16 on a steering column 18 in the motor vehicle 12, for activating left turn signal lights on the motor vehicle 12. The left turn activating structure 14 is accessible to a left thumb on a left hand of a driver of the motor vehicle 12.
Another structure 20 is also built into the steering wheel 16 on the steering column 18 in the motor vehicle 12, for activating right turn signal lights on the motor vehicle 12. The right turn activating structure 20 is accessible to a right thumb on a right hand of the driver of the motor vehicle 12, so as to enable the eyes of the driver to be free to look quickly into all mirrors 22 in the motor vehicle 12 and see if any other motor vehicles are nearby when changing lanes.
The left turn activating structure 14 is a left lane change signal button switch assembly 24. The left lane change signal button switch assembly 24 includes a left flange member 26 extending from a left side of a hub pad 28 on the steering wheel 16. A left stationary contact plate 30 mounted within the left flange member 26 is electrically connected to a left turn wire 32 within the steering column 18. A left movable contact pin unit 34 is positioned over the left stationary contact plate 30. A left button 36 is positioned over the left movable contact pin unit 34. When the left button 36 is depressed by the left thumb of the driver, the left movable contact pin unit 34 will engage with the left stationary contact plate 30, to close a left turn electrical circuit to cause the left turn signal lights to flash.
The left movable contact pin unit 34 contains a left belleville spring 38 located against a bottom surface of the left button 36. When the left button 36 is released by the left thumb of the driver, the left belleville spring 38 will cause the left button 36 to return to its original position in the left flange member 26. This allows the left movable contact pin unit 34 to disengage away from the left stationary contact plate 30 to open the left turn electrical circuit.
The left button 36 includes indicia 40 thereon to indicate to the driver that the left button 36 is for a left turn signal. The indicia 40 on the left button 36 is a left arrow 42 pointing to a left side of the motor vehicle 12.
The right turn activating structure 20 is a right lane change signal button switch assembly 44. The right lane change signal button switch assembly 44 includes a right flange member 46 extending from a right side of the hub pad 28 on the steering wheel 16. A right stationary contact plate 48 mounted within the right flange member 46 is electrically connected to a right turn wire 50 within the steering column 18. A right movable contact pin unit 52, not shown but similar to 34, is positioned over the right stationary contact plate 48. A right button 54 is positioned over the right movable contact pin unit 52. When the right button 54 is depressed by the right thumb of the driver, the right movable contact pin unit 52 will engage with the right stationary contact plate 48, to close a right turn electrical circuit to cause the right turn signal lights to flash.
The right movable contact pin unit 52 contains a right belleville spring 56, not shown but similar to 38, located against a bottom surface of the right button 54. When the right button 54 is released by the right thumb of the driver, the right belleville spring 56 will cause the right button 54 to return to its original position in the right flange member 46. This allows the right movable contact pin unit 52 to disengage away from the right stationary contact plate 48, to open the right turn electrical circuit.
The right button 54 includes indicia 58 thereon, to indicate to the driver that the right button 54 is for a right turn signal. The indicia 58 on the right button 54 is a right arrow 60 pointing to a right side of the motor vehicle 12.
