Claims20
A spray device, comprising:
- a rotatable, reversible spray tip, the spray tip having a handle for rotating the spray tip relative to a body of the spray device;
- a safety lock operatively connected to a) the body of spray device, b) a safety guard of the spray device, or c) a portion of a spray tip assembly of the spray device, the safety lock having a cover substantially conforming to the shape of the handle such that the cover is selectively engagable with the handle to prevent the handle from rotating out of a spraying position;
- and
- wherein the safety lock is hingedly connected to the spray device and allows the cover to be moved into a locked position and an unlocked position with respect to the handle.

A spray nozzle assembly with a safety lock for a spray device, comprising:
- a base connectable to the spray device, the base having an orifice to allow a coating to pass through the base, the base having a bore extending substantially transverse to the orifice;
- a spray tip having a shaft located in the base bore and rotatable therein, the spray tip shaft having a bore to allow a coating to pass therethrough when aligned with the base orifice, the spray tip having a handle;
- and
- a safety lock having a connector attached to a portion of the spray nozzle assembly, the safety lock having a cover that is engagable with the handle in a locked position that prevents the handle from being rotated such that the shaft bore is out of alignment with the base orifice;
- and wherein the cover includes at least one side having a longitudinal length extending an entire distance along a longitudinal length of the handle that prevents the handle from being rotated out of alignment with a longitudinal axis of the spray nozzle assembly when the safety lock is in the locked position.
