Abstract

A hand trigger ( 16 ) is pivotally mounted on the handlebar ( 12 ) of the striper ( 14 ). A pair of selectors ( 26 ) are pivotally mounted at the trigger pivot points. The selectors ( 26 ) are made from a spring or spring-like steel, which allows the selectors ( 26 ) to springingly deform for gun selection and adjustment yet return to their original position and shape. This allows delayed gun activation, disabling of one or both guns from the trigger ( 16 ) and functioning as a one-handed gun selector.

Description

5 parts
›TECHNICAL FIELD

This application claims the benefit of U.S. application Ser. No. 60/349,043, filed Jan. 15, 2002.

›BACKGROUND ART

Walk-behind (and self-propelled) line stripers have become a well-accepted method of applying striping to parking lots and roads. Often, it is desired to apply two parallel lines either where both are solid or where one is a dashed line. While dual gun stripers are well-known, the controls for operating both guns have proven less than completely user friendly.

›DISCLOSURE OF TH INVENTION

It is therefore an object of this invention to provide a hand control for dual-gunned stripers which may be easily and quickly adjusted between configurations without the use of tools.

A hand trigger is pivotally mounted on the handlebar of the striper. A pair of selectors are pivotally mounted at the trigger pivot points. The selectors are made from a blue tempered 1095 carbon steel or a Blu Clox spring steel which allows the selectors to springingly deform for gun selection and adjustment yet return to their original position and shape. This allows delayed gun activation, disabling of one or both guns from the trigger and functioning as a one-handed gun selector.

These and other objects and advantages of the invention will appear more fully from the following description made in conjunction with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the several views.

›BRIEF DESCRIPTION OF DRAWINGS

FIG. 1 is a perspective view of the instant invention.

FIG. 2 is an exploded perspective view of the instant invention.

›BEST MODE FOR CARRYING OUT THE INVENTION

The instant invention, generally designated 10 , is designed for mounting on the handlebar 12 of a line striper 14 . Trigger 16 is pivotably mounted to trigger block 18 by means of screw 20 , bushings 22 and nut 24 . Also pivoting about screw 20 are selectors 26 . The selectors 26 are made from a blue tempered 1095 carbon steel or a Blu Clox spring steel which allows the selectors to springingly deform for gun selection and adjustment yet return to their original position and shape. Trigger 16 has a trigger tab 16 A extending from either side.

Selectors 26 have activation 26 A and delayed activation 26 B slots therein along with cable aperture 26 C. First and second gun cables 28 and 30 respectively have ends 28 A and 30 A. The cables 28 and 30 are adjusted so that when trigger tabs 16 A are located in activation slots 26 A, the associated spray guns are activated relatively early in the trigger travel.

In operation, if one wishes to run two solid parallel lines, both trigger tabs 16 A are located in activation slots 26 A and the trigger is pulled when striping is desired. When only one line is desired, the selector 26 for the non-desired gun is moved so that trigger tab 16 is not engaged in either slot 26 A or 26 B. For spraying a solid-dashed line combination, The selector 26 for one gun is placed in activation slot 26 A and the selector 26 for the other gun is placed in delayed activation slot 26 B. The operator then needs merely to pull the trigger partway to spray the solid line while pulling the trigger 16 the rest of the way to provide the dashed line as desired.

It is contemplated that various changes and modifications may be made to the line striper gun and delay selector without departing from the spirit and scope of the invention as defined by the following claims.
