Abstract
A handle mounted trigger lever which is utilized as a solution release mechanism in an extractor is provided. The trigger switch as an `off` position and two `on` positions with the second `on` position obtainable by the depression of a release button, the release button being in a normally obstructing relationship with the trigger switch's movement in its first position. The release button includes a deformable obstructing portion which abuts with the trigger lever and limits trigger lever swing at the first `on` position. This obstructing portion may then be moved to a non-interfering relationship be deformation of the obstructing portion of the release button so that the trigger lever may then be moved to the second `on` position.
Claims6
A floor care appliance having a trigger lever arrangement including:
- (a) a valve structure providing for application of cleaning solution for said floor care appliance;
- (b) a movable control means for actuating said valve structure;
- (c) a trigger lever pivoted to said floor care appliance and moving said control means;
- (d) said trigger lever having a projection;
- (e) a button abutting with said trigger lever projection to limit said pivoting of said trigger lever;
- (f) said button having a flat abutting first face against which said projection abuts in a first position of said trigger lever;
- (g) said button having an angled second face;
- (h) said button including a spring;
- and
- (i) said projection cammingly engaging said second face of said button at a second position of said trigger lever after inward reciprocation of said button and deformation of said spring.
A floor care appliance having a trigger lever arrangement including:
- (a) a control means for applying a cleaning solution for said floor care appliance;
- (b) a trigger lever pivotally attached to said control means for initiating application of a flow of said cleaning solution by said floor care appliance and for increasing said flow of cleaning solution by greater and greater pivoting;
- (c) a button movably mounted on said floor care appliance adjacent said trigger lever;
- (d) said button being disposed adjacent said trigger lever;
- (e) said trigger lever when moving to said cleaning solution applying position abuttingly engaging said button to provide a first partly pivoted position of said trigger lever;
- (f) said button reciprocatorily mounted in a handle of said floor care appliance;
- (g) said trigger lever pivotally mounted to said handle;
- (h) said trigger lever including a portion disposed in said handle having a projection;
- (i) said projection abuttingly engaging with said button in said first position of said trigger lever;
- (j) said button including a relatively flat abutting first face against which said projection abuts in said first position of said trigger lever;
- (k) said button including a cammable, angled second face;
- and
- (l) said projection engaging said second face at a second position of movement of said trigger lever after additional inward reciprocation of said button.
