Claim 13

An automatically cancelling turn signal for motorcycles and the like having a foot-operated gear shifting lever comprising: left and right turn indicator lights; slide-type switch means including a sliding member having cammed detent means defining left, center, and right positions for said sliding member; biasing means biasing said sliding member towards said center position; a cam follower engaging said detent means for holding said sliding member in any of said positions; cam follower biasing means biasing said cam follower toward said detent means; cam follower disengagement means comprising an electromagnet operatively connected to disengage said cam follower from said detent means; and switch means in said gearshift lever for activating said electromagnet responsive to foot pressure in an upshift direction.

Claim 14

An automatically cancelling turn signal for motorcycles and the like having a foot-operated gear shifting lever comprising: left and right turn indicator lights; slide-type switch means including a sliding member having cammed detent means defining left, center, and right positions for said sliding member; biasing means biasing said sliding member towards said center position; a cam follower engaging said detent means for holding said sliding member in any of said positions; cam follower biasing means biasing said cam follower toward said detent means; cam follower disengagement means comprising an electromagnet operatively connected to disengage said cam follower from said detent means; and switch means in said gearshift lever for activating said electromagnet responsive to foot pressure in an upshift direction.

Claim 15

A turn signal system for motorcycles and the like comprising: left and right turn indicator lights; slide-type switch means for selectively manually activating said lights, said switch means having a sliding member which is slidable in a generally horizontal direction between left, center, and right positions and rotatable about its horizontal axis, said sliding member including cammed detents and having a cammed surface projecting radially outwardly from said axis; a pair of leaf switch means and a pair of electrical contact means, one of said leaf switch means being forced into engagement with one of said contacts when sliding member is moved to said left position, and the other of said leaf switch means being forced into engagement with the other of said contacts when said sliding member is moved to said right position, and said leaf switch means being forced into simultaneous engagement with both of said contacts by said radially outwardly projecting cammed surface when said sliding member is rotated about said axis; and means for activating said left and right turn indicator lights respectively in response to said leaf switch means being forced into engagement with said left and right contacts; lever means affixed to said sliding member for moving said sliding member along said horizontal axis and for rotating said sliding member about said axis.

Claim 16

A turn signal system for motorcycles and the like comprising: left and right turn indicator lights; slide-type switch means for selectively manually activating said lights, said switch means having a sliding member which is slidable in a generally horizontal direction between left, center, and right positions and rotatable about its horizontal axis, said sliding member including cammed detents and having a cammed surface projecting radially outwardly from said axis; a pair of leaf switch means and a pair of electrical contact means, one of said leaf switch means being forced into engagement with one of said contacts when sliding member is moved to said left position, and the other of said leaf switch means being forced into engagement with the other of said contacts when said sliding member is moved to said right position, and said leaf switch means being forced into simultaneous engagement with both of said contacts by said radially outwardly projecting cammed surface when said sliding member is rotated about said axis; and means for activating said left and right turn indicator lights respectively in response to said leaf switch means being forced into engagement with said left and right contacts; lever means affixed to said sliding member for moving said sliding member along said horizontal axis and for rotating said sliding member about said axis.
