Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of priority of U.S. Provisional Application Ser. No. 60/871,418 filed Dec. 21, 2006. The entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

This invention relates to devices and methods for use with spray tips. Specifically, this invention relates to paint spray tips and devices and methods of storage.

BACKGROUND

Spray painting devices use a nozzle to refine the paint into multiple droplets for application to a surface. In many commercial spray painting applications the nozzles are removable from a spray painting system. Removable nozzle tips provide ease of cleaning, and provide the ability to change nozzle tips for different paint types, or desired spray finishes, etc. One common type of nozzle tip includes a reversible nozzle tip for high pressure airless spray systems.
Commercial painters typically have several nozzle tips for various paint types, finishes, etc. It is desirable to keep multiple spray tips organized to facilitate easy location of a desired nozzle tip. It is further desirable to ensure that the tips are kept clean to provide proper spray operation.

DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings which form a part hereof, and in which is shown, by way of illustration, specific embodiments in which the invention may be practiced. In the drawings, like numerals describe substantially similar components throughout the several views. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. Other embodiments may be utilized and structural, or logical changes, etc. may be made without departing from the scope of the present invention.
FIG. 1A illustrates spray nozzle tip storage system 100 according to one embodiment. The system 100 includes a base unit 110 with a handle 112 coupled to an end. A holder 120 is shown coupled to the base unit 110. The holder includes a number of nozzle tip receptacles 122. In the example shown, the receptacles 122 are a number of holes that accept nozzle tips 130. FIG. 1 shows an end portion 132 of a nozzle tip 130 inserted within a receptacle 122. Other examples of receptacles include slots, toggle clamps, pins, etc. or other devices capable of receiving a nozzle tip 130.
In the example shown, the base unit 110 and holder 120 are formed from a material that is compatible with a paint solvent. Examples of compatible materials include selected plastics, metals, glass, etc. As will be discussed in more detail below, storage of spray nozzle tips in solvent keeps the tips in a condition ready for use at all times. Because the nozzle tips 130 are immersed in solvent, the holder 120 and other components of the storage system 100 need to be compatible with the solvent. In selected examples, the material used is transparent or translucent to help see and select an appropriate nozzle tip. Examples of solvent include, but are not limited to paint thinner, mineral spirits, lacquer thinner, etc.
In FIG. 1A, the holder 120 is shown as a flat plate. As shown in FIG. 1B, the flat plat is disk shaped in the example shown. Although plate configurations and disk shapes are illustrated, the invention is not so limited. One of ordinary skill in the art having the benefit of the present disclosure will recognize that other holder structures such as rectangular plates, or complex solid forms other than plates are also within the scope of the invention.
FIG. 1A also illustrates two holders 120 stacked over one another. Multiple plates provides the ability to store and organize more nozzle tips. Although two holders 120 are shown in FIG. 1A, other numbers of holders such as one holder, or more than two holders are within the scope of the invention.
The spray nozzle tip storage system 100 further includes a solvent reservoir 140, including a lid 142 that prevents evaporation of solvent when the nozzle tips 130 are in storage. FIG. 1A illustrates a level of solvent 144 that covers the nozzle tips 130, yet leaves the handle 112 exposed above the surface of the solvent 144. In one embodiment, the solvent reservoir 140 includes a glass jar. In one embodiment, the solvent reservoir 140 includes a box shape, or other reservoir shape. In one embodiment, the solvent reservoir 140 includes a steel paint can. Paint cans are readily available to commercial painters and provide a familiar storage system.
In one embodiment a number of legs 114 are attached to a holder 120, base unit 110, or other component of the storage system 100. Legs provide a spacing that holds the nozzle tips 130 above a bottom 148 of the solvent reservoir 140. Occasionally, sludge from old paint, etc. may build up at the bottom of the solvent reservoir. A sludge level is indicated in FIG. 1A by dotted line 146. One feature of the legs 114 is to hold the nozzle tips 130 out of the sludge 146.
In one embodiment, the legs 114 include a magnetic end. When magnetic legs 114 are used with a ferromagnetic solvent reservoir such as a steel paint can, the holder 120, base unit 110 and handle 112 are held in place. Such a configuration is useful in the event that the solvent reservoir 140 is tipped over, or jostled about during transportation. In one embodiment, the nozzle tip receptacles 122 are further equipped with securing devices to hold the nozzle tips 130 in place within the nozzle tip receptacles 122. In the event that the solvent reservoir 140 is tipped over or jostled, the securing devices keep the nozzle tips 130 from falling out of place and becoming disorganized.
One example of a securing device is shown in FIGS. 1A and 1B as a starburst pattern cut into a resilient material such as a polymer gasket. FIG. 1B shows a number of slits 123 in a resilient material for each nozzle tip receptacle 122. Although a starburst pattern is shown for use as a securing device, the invention is not so limited. Other configurations of securing devices including those discussed below regarding FIG. 3 are also within the scope of the invention.
In one embodiment, a laminate structure is used to form the securing devices. FIG. 1A illustrates a first resilient material layer 124, a rigid layer 126, and a second resilient layer 128. In one embodiment, the first and second resilient layers 124, 128 are formed from a polymer gasket material. Other resilient materials such as rubbers, or plastics, etc. that are compatible with paint thinner, lacquer thinner, or other solvents are also within the scope of the invention.
FIGS. 2A and 2B illustrate possible configurations of rigid layer 126 and first resilient layer 124. In one embodiment, the first resilient layer 124 and the second resilient layer 128 are substantially identical. FIG. 2A shows a number of holes 210 that serve as nozzle tip receptacles. A center hole 202 is shown as option for attachment to a base unit. FIG. 2B shows a starburst pattern 220 that serves as a securing device to hold nozzle tips in place within the holes 210. A center hole 204 is further shown as an option for attachment to the base unit.
FIG. 3 shows another configuration of a holder 320 that may be used in a manner similar to embodiments described above. A center hole 321 is shown as an option for attachment to a base unit as in other embodiments. A nozzle receptacle 322 is shown to accept a nozzle tip 130 as illustrated. FIG. 3 shows an o-ring 324 or similar resilient component inserted within the nozzle receptacle 322. In one embodiment, the o-ring 324 is held captive within a number of laminated layers 325, 326, 327 that form the holder 320. An inner diameter 328 of the o-ring 324 as shown forms an interference fit with the nozzle tip 130.
Although starburst patterns and grommets are discussed in detail, the invention is not so limited. Other securing device configurations such as alternative slit patterns, resilient grommets, mechanical holders, etc. are within the scope of the invention.
FIG. 4 shows a flow diagram of an example method of use. In operation 410, a user places one or more spray nozzles tips in respective nozzle tip receptacles such as those described in embodiments above. In operation 412, the user then lowers the nozzle tips into a reservoir of solvent using a handle that is coupled to a holder similar to embodiments described above and covers the reservoir in operation 414 to prevent solvent evaporation. The handle is not submerged within the solvent, thus allowing the user to later remove the nozzle tips without getting his or her hands wet. Previous systems required a user to fish for a desired nozzle tip within solvent, or to dump everything out and start again with new solvent.
Using devices and methods described in the present disclosure, a user can easily store and later find any one of several nozzle tips from within a solvent reservoir. Devices and methods shown allow a user to store and retrieve nozzle tips without immersing fingers or hands in solvent, which can be harsh and/or damaging to skin. Selected embodiment further allow the solvent reservoir to be tipped over or otherwise jostled without the stored nozzle tips becoming dislodged from their organized locations.
