BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to spraying equipment, and more particularly to a device which can be attached to the top of a bucket for spraying liquid from the bucket.
2. Description of Related Art
Many liquids that are to be sprayed are sold in buckets, particularly in five gallon plastic buckets. Such liquids can include paints, sealers for concrete or asphalt surfaces, roofing sealer, etc. Typically such liquid is purchased, taken to the job site and then poured into another container associated with a sprayer before the actually spraying is done. Of course this step of transferring the liquid to another container takes time. Furthermore the container to which the liquid is transferred will need to be cleaned at times, especially if a different liquid is to be sprayed than the one last used in such container.
Electrically operated sprayers often need an electrical outlet in order to be operable. That is not always convenient because the spraying may be needed at a location remote from electrical power. Additionally, even if an extension cord will reach an outlet, the extension cord itself can create a safety hazard or make the spraying more difficult because it gets in the way or may even pick up liquid from the sprayer or sprayed surface.
Accordingly there is a need for spraying equipment to overcome these problems with prior art devices.
SUMMARY OF THE INVENTION
The present invention relates to a spraying apparatus which can be attached directly to a bucket in which a liquid is sold. One part of the invention is an apparatus which permits the bail of such bucket to be used to lock the spraying apparatus to the bucket so that the spraying apparatus is held securely in place while the liquid is sprayed directly from the container in which it is sold. Another part of the invention uses a rechargeable battery of the type used in power tools, and which is held securely in place during the process of spraying a liquid directly from a bucket.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings wherein like reference numerals designate identical or corresponding parts throughout the several views, FIG. 1 shows a device 10 constructed in accordance with a preferred embodiment of the present invention and being used to spray a sealant on concrete.
FIGS. 1-6 show the invention 10 with a housing 11 with a housing plate 11a attached thereto. The housing 11/11a is attached to a bucket 12 so that liquid 26 in the bucket can be sprayed out of hose 14 and sprayer wand 13 through nozzle 15.
A member 17 is pivotally attached to the housing 11, as shown in FIG. 6, by threaded fasteners 19 that extend through flanges 18 attached to the top of housing 11. The member 17 has notches 17a, 17b and 17c, though more or less notches can be used as will be explained below. Portion 17d of member 17 abuts the top of a rechargeable battery 21, which will be discussed below.
The device shown in FIG. 6 can be attached to a bucket 12 full of liquid 26 as shown in FIGS. 3-7. FIG. 3 shows how a rechargeable battery 21 with a projection 21a with plus and minus contacts thereon can be alternatively plugged into and attached to the top of the housing 11 and held in place by the member 17 or plugged into a charger 41 of the type commonly used in portable power tools such as electric drills. Furthermore, the device shown in FIG. 6 can be placed on top of a bucket 12 in the manner shown in FIG. 3 and once in place the bail 20, with handle 20a, can be moved to the position shown in FIG. 5 so that the bail is in notch 17a. This will hold, by friction, the device of FIG. 6 securely to the bucket 12. The bail 20 is typically made of steel which will act as a spring when stretched to go into the notches 17a and then pull the housing 11 downwardly to keep the bail 20 in the notches 17a. If a larger bail 20 is used, then one of the higher notches 17b or 17c would be used instead of notches 17a. In this way the bail 20 and the pivoting member 17 hold the housing 11 onto the bucket 12 and at the same time hold the battery 21 securely in place by contact of 17d with the top of the battery 21.
As shown in FIG. 3 going sequentially from top to bottom, the latch member 17 on top of the pump 28 should not be rotated or latched until the bucket handle bail 20 is rotated up to engage one of the sets of notches such as 17a, then both the latch member 17 and bucket handle bail 20 will pivot simultaneously, counterclockwise as shown in FIG. 3. Once the latch member 17 and bucket handle bail 20 are engaged, when rotated counterclockwise, they will cam or toggle over the center point, locking the pump assembly to the bucket 12 and securing the battery 21.
Of course rechargeable batteries 21 come in various sizes, shapes, voltages, etc. If a person prefers a certain brand of power tools, then such person would most likely want to purchase one of these devices 10 that would use the same size and shape of battery as in that person's power tools. Accordingly the invention 10 can be modified as needed to accommodate various sizes and shapes of rechargeable batteries 21.
Before or after the housing 11 is attached as shown in FIG. 5, the hose 14, wand 13 and nozzle 15 can be attached. Similarly, the inlet conduit 24 is operatively attached to the inlet of the pump 28 through conduit 29, which is in liquid communication with conduit 24. The pump is powered by an electric motor 27. This conduit 24 can go through a hole in optional lid. In other words, the device can be attached to a bucket 12 that has a lid with a hole in it or the device can be attached to a bucket without a lid. The upper rim 12a can represent the top rim of a bucket lid or upper rim 12a can represent the top of the bucket 12 with no lid on it. In most instances the bucket 12 will have a lid on it when such bucket 12 is purchased with a liquid to be sprayed inside. That being the case, the lid would preferably remain on the bucket 12 during use of the present invention.
Looking to FIGS. 8-10, the outlet of the pump 28 has an outlet conduit 31 and a fitting 32 operatively attached thereto so that the hose 14 can be attached to fitting 32 and thereby be in liquid communication with the outlet of the pump 28. Once all of the parts are assembled as shown in FIGS. 1 and 7, it is just a matter of spraying all of the liquid 26 from the bucket 12 and then attaching it to another bucket 12 that has been purchased that is full of liquid 26. This is done instead of just filling the emptied bucket 12.
Accordingly, it will be appreciated that the preferred embodiments do indeed overcome the deficiencies of the prior art explained above. Obviously many modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
