Abstract

A device for manually painting a large surface using a spray gun connected to a paint feed line for the supply of an enamel paint and to a pressure line for the provision of compressed air. After the manual actuation of an operating switch arranged on a handle piece, the spray gun sprays the enamel paint by compressed air via a spray head to apply the enamel paint onto the surface. The spray gun includes means such that it can be moved manually along the surface. The means include an extension rod, at one end of which the spray gun is attached by the handle piece and which is configured such that, when held by an operator on an arm holder configured at the opposite end, it extends from the elbow along the forearm of the operator and beyond the distal end of the forearm.

First claim

The invention claimed is:

1. A device for manually painting a large surface comprising:
a spray gun connected to a paint feed line for the supply of an enamel paint and to a pressure line for the provision of compressed air,
wherein the spray gun is configured, after the manual actuation of a first operating switch arranged on a handle piece, to spray the enamel paint by compressed air via a spray head to apply the enamel paint onto the surface,
wherein the spray gun further comprises means configured to move the spray gun manually along the surface,
wherein the means for manually moving the spray gun along the surface comprise an extension rod, wherein the spray gun is attached to a first end of the extension rod by the handle piece and wherein the extension rod is configured such that, when held by an operator on an arm holder configured at an opposite end, the extension rod extends from the elbow along the forearm of the operator and beyond the distal end of the forearm,
further comprising a second operating switch fitted on the handle of the arm holder and connected to the first operating switch of the spray gun via a Bowden cable to remotely actuate said first operating switch from the arm holder.

2. The device according to claim 1 , wherein the arm holder of the extension rod comprises a handle extending away from the extension rod in a substantially vertical direction, and
wherein the handle comprises a second operating switch in mechanical connection with the first operating switch.

3. The device according to claim 1 , wherein the arm holder comprises at the end an arm support to at least partly surround the forearm of the operator.

4. The device according to claim 1 , wherein the extension rod has on the end facing the spray gun a clip-shaped fastening unit for a releasable attachment to the handle piece of the spray gun.

5. The device according to claim 1 , wherein the extension rod comprises a plurality of parts and is configured to be adjusted in length telescopically by a locking or clamping mechanism.

6. The device according to claim 1 , wherein the extension rod comprises at least one light metal pipe electrically earthing the spray gun.

7. The device according to claim 1 , wherein the extension rod comprises at least one plastics material pipe, and an electric conducting wire running in or on the pipe for earthing the spray gun.

8. The device according to claim 1 , further comprising a supporting sling configured to be positioned around the operator's body and attached at the end, associated with the spray gun, of the extension rod.

9. The device according to claim 1 , wherein the paint feed line and the pressure line are secured on the extension rod.
