Media protection system for line demarcation

Abstract

This invention is method to protect secondary media from the environmental conditions that exist while performing line demarcation. Particularly, this invention relates to the protection of dry media as it is applied to previously applied, wet media. More particularly, this invention relates to the protection of reflective glass beads as they are applied to freshly applied wet paint.

4. The protection apparatus of claim 3, wherein the top portion is separated from the bottom portion by a channel.

5. The protection apparatus of claim 4, wherein the top portion is substantially parallel to the bottom portion.

6. The protection apparatus of claim 5, wherein the top portion and the bottom portion are each trapezoidal in shape as viewed from above.

7. A protection apparatus for use with a media distributing system having an opening for expelling a media, the protection apparatus comprising; a shield comprising a top portion separated from a bottom portion by a channel, the shield mounted to the media distributing system proximate the opening; a guiding arm movably connected to the shield, wherein the guiding arm is configured to direct the media and, wherein at least an internal portion of the guiding arm is located inside the channel; and a dial having at least an external portion located outside the shield, wherein the dial, is operatively connected to the guiding arm.

8. The protection apparatus of claim 4, wherein the top portion further comprises a cutout and the opening is located proximate the cutout.

9. The protection apparatus of claim 8, wherein the media distribution system passes through the cutout such that the opening is located in the channel.

10. The protection apparatus of claim 9 wherein the guiding arm comprises a first guiding arm and is located in the channel, the protection apparatus further comprising a second guiding arm located in the channel and movably connected to the shield, wherein the second guiding arm is configured to direct the media.

11. The protection apparatus of claim 10, wherein the opening is located in the channel between first guiding arm and the second guiding arm.

12. The protection apparatus of claim 3, wherein the first wing and the second wing each are spaced apart from the top portion.

13. The protection apparatus of claim 3, wherein the top portion and bottom portion are formed from distinct elements and wherein the top portion is connected to and spaced apart from the bottom portion by one or more fasteners.

14. The protection apparatus of claim 13, wherein each of the one or more fasteners comprise one or more bolts, washers, and nuts.

15. The protection apparatus of claim 3, wherein each of the top portion and bottom portion is steel, plastic, or aluminum.

16. A method for controlling a spread of media expelled from a media distributing system using a protection apparatus comprising a top shield separated from a bottom shield by a channel, a guiding arm located at least partially within the channel, and a dial operatively connected to the guiding arm and located at least partially outside the channel, the method comprising the steps of: movably attaching the guiding arm to the top shield attaching the top shield to the bottom shield; attaching the media distributing system to the protection apparatus; and positioning the dial so as to obtain a desired spread of media.

DETAILED DESCRIPTION

(8) The present invention is a media protection system that guards secondary media from the high-pressure emissions of a primary spray system as well as windy environmental affects on by encasing the media output by one or more shields. The top shield (1) can be made of steel, aluminum or plastic and can be opaque or clear so the operator can confirm that the media is being sprayed. The preferred embodiment of the shield would be a one-piece unit that slips over the existing bead deflecting unit (10) which comes as a standard part of existing bead gun assemblies. FIG. 2 shows a side view of the primary and secondary spray guns with a shield unit (15) with a top plate (1), the bottom plate (2), and the external dial (3) that is attached to the existing bead deflector (10). The two plates create a channel (12) for the reflective media (16) to travel through on its way to the paint (13) that has been previously sprayed on the ground (14) below the shield unit (15). The open sides (11) allow for pressure equalization between the high pressure in the channel and the low pressure outside of the shield. FIG. 3 shows the wings on the bottom plate that extend off of the shield plate and are angled to protect the channel (11) from winds that hit the shield perpendicular to the direction of spraying machine. The wings are essential to ensure that the channel is protected in 360 degrees. FIG. 4 shows the top plate, which has a cutout so that the shield assembly can mount on the existing, universal bead deflector which screws to the end of the media spray gun (17). FIG. 5 represents a potential embodiment of the shield system assembly noting the use of the bead deflector hardware to connect the shield to the deflector. The preferred embodiment is a unibody shield and deflector in one. FIG. 6 shows a detail view of one the externally accessible dial. The dial handle (8) is manipulated to move the guiding arm (9). The guiding arm moves in and out to aim the media depending on the conditions as the beads leave the shield.
