Abstract
Abstract A combination switching means of the lever type includes a lever having a double-shaft construction so as to permit an operational shaft to be extended through the inside thereof. A first switching means is actuated through a first tilting pivotal operation of the lever, and a second switching means is actuated through a second tilting pivotal operation of the lever in a direction perpendicular to the first pivotal direction. A third switching means is actuated through a twisting pivotal actuation of the operating shaft. A first constructional arrangement prevents an undesirable transmission of a specific displacement inherent in the first pivotal operation to the other switching means, a second constructional arrangement prevents an undesirable transmission of a specific displacement inherent in the second pivotal operation to the third switching means.

Claim 1
Independent Claim
398 words
A combination switching assembly of the lever type for use in a motor vehicle, said assembly comprising: a support frame adapted to be mounted on a steering column of a motor vehicle, said support frame having projecting therefrom a pivot shaft; a lever support member mounted to pivot about said pivot shaft; a hollow operating lever; supporting shaft member means for connecting said operating lever to said lever support member such that upon application to said operating lever of a first tilting pivotal movement in a first direction said operating lever and said lever support member together pivot about said pivot shaft, and such that upon application to said operating lever of a second tilting pivotal movement in a second direction substantially perpendicular to said first direction said operating lever pivots with respect to said lever support member about an axis of said supporting shaft member means; first, second and third switching means, fixed with respect to said support frame, for achieving first, second and third switching operations, respectively; first operating member means, connected to said lever support member, for, upon movement of said operating lever and said lever support member about said pivot shaft in said first direction, actuating said first switching means; first sliding member means, mounted for sliding movement with respect to said support frame, for actuating said second switching means; second operating member means, connected to said operating lever, for, upon movement of said operating lever in said second direction, causing said first sliding member means to actuate said second switching means, and for, upon movement of said operating lever in said first direction, preventing sliding movement of said first sliding member means and thus preventing actuation of said second switching means; an operating shaft extending coaxially through the interior of said operating lever and being mounted therein for twisting rotational movement with respect thereto; second sliding member means, mounted for sliding movement with respect to said support frame, for actuating said third switching means; and third operating member means, connected to said operating shaft for, upon twisting rotational movement of said operating shaft with respect to said operating lever, causing said second sliding member means to actuate said third switching means, and for, upon movement of said operating lever in said first or second directions, preventing sliding movement of said second sliding member means and thus preventing actuation of said third switching means.
Claim 2
Dependent Claim
398 words
A combination switching assembly of the lever type for use in a motor vehicle, said assembly comprising: a support frame adapted to be mounted on a steering column of a motor vehicle, said support frame having projecting therefrom a pivot shaft; a lever support member mounted to pivot about said pivot shaft; a hollow operating lever; supporting shaft member means for connecting said operating lever to said lever support member such that upon application to said operating lever of a first tilting pivotal movement in a first direction said operating lever and said lever support member together pivot about said pivot shaft, and such that upon application to said operating lever of a second tilting pivotal movement in a second direction substantially perpendicular to said first direction said operating lever pivots with respect to said lever support member about an axis of said supporting shaft member means; first, second and third switching means, fixed with respect to said support frame, for achieving first, second and third switching operations, respectively; first operating member means, connected to said lever support member, for, upon movement of said operating lever and said lever support member about said pivot shaft in said first direction, actuating said first switching means; first sliding member means, mounted for sliding movement with respect to said support frame, for actuating said second switching means; second operating member means, connected to said operating lever, for, upon movement of said operating lever in said second direction, causing said first sliding member means to actuate said second switching means, and for, upon movement of said operating lever in said first direction, preventing sliding movement of said first sliding member means and thus preventing actuation of said second switching means; an operating shaft extending coaxially through the interior of said operating lever and being mounted therein for twisting rotational movement with respect thereto; second sliding member means, mounted for sliding movement with respect to said support frame, for actuating said third switching means; and third operating member means, connected to said operating shaft for, upon twisting rotational movement of said operating shaft with respect to said operating lever, causing said second sliding member means to actuate said third switching means, and for, upon movement of said operating lever in said first or second directions, preventing sliding movement of said second sliding member means and thus preventing actuation of said third switching means.
Claim 3
Dependent Claim
39 words
An assembly as claimed in claim 1, further comprising contact holder means mounted for sliding movement with respect to said support frame and adapted to be moved by said first operating member means, for actuating said first switching means.
Claim 4
Dependent Claim
31 words
An assembly as claimed in claim 2, wherein said first operating member means includes a substantially U-shaped groove, and said contact holder means includes a portion received within said U-shaped groove.
Claim 5
Dependent Claim
31 words
An assembly as claimed in claim 1, wherein said first sliding member means slides in a direction substantially perpendicular to the direction of sliding movement of said second sliding member means.
Claim 6
Dependent Claim
33 words
An assembly as claimed in claim 1, wherein said first sliding member means has therein a substantially circular recess, and said second operating member means has a rounded portion engaging said circular recess.
Claim 7
Dependent Claim
78 words
An assembly as claimed in claim 1 or in claim 5, wherein said second sliding member means includes a substantially U-shaped groove, said third operating member means includes a portion received within said U-shaped groove, and the size of said U-shaped groove is such that upon said operating lever moving in said second direction said portion of said third operating member means moves fully within said U-shaped groove without imparting sliding movement to said second sliding member means.
Claim 8
Dependent Claim
63 words
An assembly as claimed in claim 6, wherein engagement between said portion of said third operating member means and said second sliding member means within said U-shaped groove occurs at a position substantially axially aligned with the axis of said pivot shaft, such that movement of said operating lever in said first direction will not cause said second sliding member means to slide.
Claim 9
Dependent Claim
53 words
An assembly as claimed in claim 1, wherein said third operating member means engages said second sliding member means at a position substantially axially aligned with the axis of said pivot shaft, such that movement of said operating lever in said first direction will not cause said second sliding member means to slide.
Claim 10
Dependent Claim
54 words
An assembly as claimed in claim 1, wherein said first switching means comprises means for operating direction turn signal blinking lights, said second switching means comprises means for changing the beam level of head lamps, and said third switching means comprises means for selectively operating said head lamps and other lamps of the vehicle.
