Umbrella base
An umbrella base is comprised of a body portion having a billboard surface for advertising a company, organization, products, service or the like. The billboard surface can be provided on a separate removable billboard plate placed on the top of the body portion, which allows the advertising message to be easily changed. In its preferred construction, the body portion has at least one ballast cavity, and preferably multiple ballast cavities, and is constructed in separable parts to permit a selected ballast to be added to the ballast cavities in order to add a desired ballast weight to the umbrella base. The umbrella base can also be provided with casters, including locking casters, so that the umbrella base and its advertising message can be easily moved across a surface from one location to the another.
This application claims the benefit of Provisional Application No. 60/533,737, filed Dec. 29, 2003.
BACKGROUND OF THE INVENTIONThe present invention generally relates to the use of umbrellas, and in particular, to umbrella bases used to hold umbrellas in an upright position.
Outdoor and patio umbrellas (collectively referred to as patio umbrellas) are widely used in personal, recreational and commercial settings. Typical commercial purchasers of patio umbrellas include hotels, resorts, restaurants, cafes, pubs and coffee houses. Because of their widespread use and the visual exposure they provide to users and passers-by, patio umbrella's have been popular as a media for corporate advertising. As more people spend time outside and become more educated about the harmful effect of the sun's direct rays, the demand for patio umbrella's is likely to increase along with the opportunity for providing advertising centered around the patio umbrella. Heretofore, such advertising has been limited to imprinting or otherwise incorporating company names, product names, logos and the like directly on the umbrella's fabric covering, where the advertising is within normal sight lines of persons situated at a distance from the umbrella, however, where the advertising cannot be easily viewed by persons close in, such as persons seated under the umbrella.
Therefore, there is a need for increasing the opportunities for corporate and other types of advertising associated with the patio umbrella that have not heretofore existed. There is also a need to provide a vehicle for corporate advertising associated with patio umbrella's that is visually prominent and within sight-lines of people seated or standing underneath or close to the umbrella in a manner not provided by conventional advertising specialty umbrella's. These needs are fulfilled by the present invention by means of a novel umbrella base capable of providing a visible advertising message beneath the umbrella held by the base.
There is also a need for an improved umbrella base that can easily be moved from one location to the other and that can be adapted to support umbrellas of different sizes and weights and in different weather environments. Weight is an important issue for patio umbrella bases. A user or manufacturer must normally determine the weight required to support a patio umbrella for given conditions. This determination depends on several variables, including the weight and span of the patio umbrella to be supported, and the location and environmental conditions in which the patio umbrella is to be used. For example, a heavier base would be more suitable for a patio umbrella that is to be used in an exposed outdoor area where wind loads are frequently high. On the other hand, if the patio umbrella is to be used in a relatively sheltered or non-exposed area, such as inside a large building or sheltered area, or underneath a table, a lighter base would suffice. Too much weight is undesirable because the base would be excessively heavy and difficult to move. The added weight may also lead to increased shipping costs. Insufficient weight would make the umbrella susceptible to being toppled by wind or other forces.
Heretofore, different umbrella bases having different weights have typically been designed for different use environments. For example, umbrella bases using a form of cast iron or metal bottom plate have been popular for supporting outdoor patio umbrellas that are quite large and heavy and that require a heavy and stable umbrella base for adequate support. A conventional cast iron base will typically weigh about fifty to seventy pounds. Such weight is adequate to support some patio umbrellas in some environments, however, it may be inadequate depending on weather conditions and the umbrella size. Also, metal bases are susceptible to corrosion which results not only in the deterioration of its outer appearance, but also creates a problem when rust particles stain the surrounding support surfaces such as wood or concrete. Protective coatings such as rust resistant paint and even high cost powder coatings have been used to help alleviate this problem, however, in high traffic areas repeated contact with tables and chairs can cause scratches in the surface coatings allowing the metal beneath the protected surface to rust.
Another known form of an umbrella base is a simple, typically hemispherical block of concrete having an imbedded vertical pipe for receiving the end of an umbrella. Such bases are heavy, unattractive and difficult to move, and not well adapted for many use environments.
Yet another umbrella base design that has heretofore been used is a base that is rotationally or blow molded from plastic to form a one piece hollow body similar in construction to a milk container. This molding process produces low cost, rust resistant parts, however, the parts generally are large and bulky and cosmetically unattractive. Also, they are produced with a relatively thin and uniform wall thickness making it difficult to attach the necessary structural tubing to hold the umbrella shaft. Rotationally or blow molded bases are usually located in a predetermined location and then filled with suitable fluid ballast such as water through a small fill opening to provide the weight necessary to support the umbrella. Once filled, they are very difficult to move without the draining of the fluid ballast.
The difficulty in moving conventional umbrella bases is a significant drawback. As the sun transitions throughout the day, the shade from the umbrella moves from one location to another. If tables and chairs have been arranged below the umbrella to shade the early morning sun, by afternoon these chairs and tables are now in the direct sunlight. The umbrella themselves have been designed to allow for some sun correction by allowing the user to tip or angle the umbrella to offset the suns movement. However, because of the difficulty in moving existing umbrella bases and because the offset angle of the umbrella only offers minimal shade adjustments, users usually need to move their table and chairs to the new shaded area as the day progresses.
The present invention overcomes the above-mentioned shortcomings of previous umbrella bases by providing for an improved umbrella base that, in its various novel aspects, provides an advertising message, is relatively compact, is adapted to aesthetically pleasing profiles and adapted to top surfaces for readily visible advertising messages, has structural integrity, and allows the user to select a desired base weight depending on size and weight of the umbrella to be held and environmental conditions in which it will be held. The present invention also provides an umbrella base that, regardless of its weight, can be transported or maneuvered from one location to another with relative ease, and that can be readily locked into a set location after it has been moved.
SUMMARY OF INVENTIONIn one of its aspects, the present invention provides an umbrella base comprised of a body portion with a billboard surface on which advertising indicia is provided for advertising a company, organization, product, service or the like. The billboard surface can be any surface of the umbrella base that is readily visible to persons in the vicinity of the umbrella base, and could include top surfaces and/or vertical sidewall surfaces. The base further includes an umbrella holding structure accessible from the top of the body portion to receive the support shaft of an umbrella for holding the umbrella in an upright position. Preferably, the billboard surface includes a top, substantially flat horizontal surface that surrounds the umbrella holding structure. In another aspect of the invention, the top billboard surface is removable from the top portion of the body such that advertising messages on the umbrella base can be interchanged by replacing one top billboard surface with another top billboard surface.
In a further aspect of the invention, the body portion of the umbrella base is comprised of a ballast housing assembly which includes a lower portion having at least one ballast cavity that can be filled with a ballast material, such as water, sand, steel shot, iron, lead, concrete, cement. The housing assembly further includes a top portion that removably fits onto the lower portion of the housing assembly to cover the at least one ballast cavity. The removable cover portion provides access to the ballast cavity without the need for narrow fill openings for the ballast material, and permits aggregate ballast materials such as sand or cement to be distributed evenly within the cavity. The ballast cavity is optionally divided into smaller cavities such as by partition walls disposed in the cavity. Multiple cavities facilitate even distribution of the ballast material within the lower ballast holding portion of the housing and minimize shifting of the ballast material within the base when the base is moved or tipped. They also facilitate the use of relatively small easy to handle ballast containers sized and shaped to fit within the cavities. Specific cavity volumes can also be provided to predetermine the amount of ballast weight that will be added for a given ballast material.
In an alternative embodiment of the invention, at least one closable fill opening is provided in the top cover portion of the housing assembly to permit the at least one the ballast cavity in the lower housing portion to be filled with a ballast material without having to remove the top cover of the housing assembly. For bases having multiple ballast cavities, a closable fill opening is provided for each cavity.
The invention contemplates other housing assembly configurations with separable parts for accessing internal filling ballast cavities, including a housing assembly having a housing top open at the bottom and a bottom cover plate that can be removed for filling the ballast cavities while the umbrella base is turned upside down.
The foregoing ballast housing assembly can readily be combined with the advertising billboard aspect of the invention. The top cover portion of the housing assembly preferably has a substantially flat and laterally extending top surface with a center opening for the umbrella holding structure, which is suitably a cylindrical pipe anchored to the lower portion of the housing assembly. This top surface can alternatively provide a billboard surface for advertising indicia or a support surface for a removable billboard plate that can be readily replaced with other billboard plates to change the advertising message.
In still another aspect of the invention, the lower portion of the housing assembly is provided with casters to allow the base to be readily moved from one location to another, and with position locking mechanisms for locking the base in a set position when it is not being moved. In one embodiment, at least one of the casters, and suitably two or more casters, has a locking mechanism that is activated by the user. When the base is ready to be moved, the user mechanically unlocks each caster that has a locking mechanism and rolls the base to a new location. After the base is moved the user activates the wheel locks again to prevent any further rolling movement. In the preferred embodiment, the casters are wheel casters and the locking mechanisms engage the caster wheels to prevent rolling of the wheels.
In another embodiment of the invention, the lower portion of the housing assembly includes casters and deployable support feet. At least three, and suitably more support feet are provided for stability and are attached to the lower portion of the housing assembly so that the feet can be lowered to engage the ground to take the weight of the umbrella base off of the casters, and retracted for lowering the base back onto the casters for rolling. In the preferred embodiment, the deployable support feet are provided in the form of spring-loaded user activated cam devices, and are preferably located at or somewhat beyond the perimeter of the housing assembly for ease of access and maximum stability.
Therefore, a primary object of the present invention is to provide an improved umbrella base that can be used to advertise products, services, company names, company logos, names and symbols of organizations such as universities, and the like. It is another object of the invention to provide an improved umbrella base having at least one readily accessible ballast cavity that can be easily filled with a suitable ballast material and that facilitates providing variable ballast weights to accommodate different uses and use environments. It is a further object of the invention to provide an umbrella base that can be easily moved from one location to another, and that can be rendered immobile at a set location. It is still another object of the invention to provide an umbrella base which is aesthetically pleasing, that is durable in outdoor weather, yet is relatively inexpensive to manufacture. One or more the foregoing objects may be attained in a particular embodiment of the invention and a particular embodiment of the invention need not attain all of the foregoing objects. Also, other objects of the present invention will become apparent to those skilled in the art from the following description, the accompany drawings and the appended claims.
DESCRIPTION OF THE DRAWINGS
The present invention provides a novel umbrella base of the type used to hold the shaft of an umbrella such as a patio umbrella. In its various aspects the umbrella base of the invention provides mobility, can be stabilized once it reaches its predetermined location, has operative components that can be easily be removed and attached, such as for filling the base with a ballast material, and provides. an easily viewed advertising display, including an interchangeable display.
Referring now to the drawings,
The housing assembly 27 is seen to comprise a lower portion 50 (sometimes. referred to as the “lower housing”) and top cover portion 60 (sometimes referred to as the “housing cover”), both of which are preferably fabricated of an injection or structural foam molded polymer with UV resistance, such as high-density polyethylene (HDPE), but which could be fabricated of other materials. As shown in
As later described, the ballast cavities of the lower housing portion of the housing assembly can be configured to receive a ballast container which is filled with a ballast material or contains a ballast weight. Such containers may be a rigid containers of a fixed size and shape or non-rigid containers such as cloth or plastic bags for holding a volume of ballast material that fits within the ballast cavities. It is also understood the lower housing 50 can be constructed with no partition walls such that there is only one large ballast cavity. It will further be appreciated that more or less partition walls can be used to segment the ballast cavity of the housing assembly into a greater number or lesser number of ballast cavities than the number of ballast cavities. illustrated in the drawings.
The top cover portion 60 of housing assembly 27 has a flat, laterally extending top wall 61, which includes a raised perimeter rim 61a and a raised central collar 61b that receives the top portion of the upwardly projecting retaining sleeve 51 of the lower housing 50, when the housing cover is placed on the lower housing. As best shown in
The top cover and lower portion of the housing assembly are held together by finger releasable snap latches 32 spaced around the perimeter of the housing cover, which insert into corresponding latch channels 32a formed on the perimeter of the lower housing portion. As shown in
The umbrella base 25 is also provided with casters to allow the base to be moved from one location to another with minimum physical effort. The illustrated casters are standard off-the-shelf wheel casters 65 having a frame 68, suitably fabricated of zinc plated forged steel, and caster wheels 69, which are preferably non-marking, shock resistant polyurethane wheels for economy and long life. As best shown in
As illustrated in
Referring to
It is understood that other constructions of the brake assembly are possible. For example, the sheet-metal bracket 75 of the brake assembly could be incorporated into the metal frame 68 of the wheel caster as a one-piece assembly.
As best seen in
The billboard plate 70 is mechanically attached to the top wall 61 of the housing assembly's top cover portion 60 by means of self-threading screws 71. Screws 71 are seen to screw into screw holes formed in bosses 72 formed on the underside of the billboard plate to fit into corresponding recesses 72a in the housing cover's top wall 61. While the billboard plate self aligns and is retained on the top wall 61 by means of the rim 61a and center collar 61b, mechanical attachment by screws 71 will prevent dislodgment of the billboard plate when the umbrella base is tipped or moved, and will deter theft of the logo bearing billboard plates. The billboard plate can alternatively be provided without a mechanical attachment or with other forms of attachment such as molded-in snap attachments.
It is seen that billboard plate 70 provides a readily visible top billboard surface 73 which surrounds the support pipe holding the umbrella shaft 31. Preferably, advertising indicia are applied to this top surface about the support pipe (such as shown by the two logos L. The advertising indicia can be located on and about, and cover any portion of the top billboard surface 73 to provide a desired advertising display, and can be applied or otherwise provided on this surface in any number of ways, including by silk-screening or painting the indicia directly on the top surface of the plate or by applying separate multi-colored labels or laminates bearing an advertising message. A suitable label having clear UV resistant lamination 90 can be permanently applied to the billboard plate as shown in
It shall be understood that the invention is not limited to an umbrella base having a removable billboard plate, and that the top cover portion of the housing assembly can have a billboard surface integral with the top wall of the cover portion. In this case advertising indicia such as company logos L would be applied or otherwise provided directly on the top wall 61 of the housing assembly's top cover portion 60. Also, it is contemplated that the sidewalls 62 of the umbrella base could provide billboard surfaces for advertising indicia instead of, or in addition to the housing cover's top wall 61. These sidewall logos, which are represented by logos L2 in
As shown in
The bottom of the central sleeve structure 51 of the lower portion of the housing assembly is adapted to receive a cap screw assembly comprised of a standard threaded bolt or cap screw 48, washer 59 and threaded locking nut 63 as shown in
Instead of using a rigid fillable ballast container, ballast can alternatively be provided in a non-rigid container, such as tie or zip bag 88. Such containers would normally be used with aggregate ballast materials only, but have the advantage of being inexpensive and easily stored and transported. Their shapes are also fluid, allowing them to easily conform to the configuration of the ballast cavities.
As a further alternative, ballast can be added to the ballast compartments 53 of the base by means of a fixed ballast form 89, which could be an enclosed rigid container pre-filled with a ballast material or liquid, or a pre-formed block of material of a predetermined weight, such as concrete. Such ballast forms could also provide utilitarian components for the umbrella base such as one or more batteries to serve as a power source for umbrella lights or the like.
More specifically, each support foot assembly includes a frame structure 101, suitably fabricated of HDPE or polypropylene plastic, having an inner part 101a and outer part 101b. As shown for example in
Once a location has been set and the user wishes to stabilize the umbrella base 25, he or she does so by inserting a coin, such as a quarter 110 or a special tool into the slot 111 formed in the top of cam-screw 102, and pushing down and rotating the cam-screw clockwise, as depicted by the arrows in
It is contemplated that the umbrella base 25 shown in
To assemble the umbrella base, the billboard plate 70, if not preinstalled, is first placed on top of the housing cover 60 and screws 71 inserted as shown in
To change an advertising message, the billboard plate 70 can be exchanged with another billboard plate. This is accomplished by removing the top cover of the housing assembly and then removing screws 71, which hold the billboard plate to the top cover of the housing assembly. A new billboard plate is then screwed onto the top cover and top cover reinstalled as above-described. It will be understood that alternative constructions of the umbrella base are possible that provide for other assembly steps or the elimination of steps. For example, the billboard plate could be provided without screw attachments and possibly in two halves or in more segments to allow the billboard plate to be removed without any disassembly of the housing.
In this embodiment, the support pipe 132 is split into two sections, namely, top section 133 and bottom section 134, having joinable ends 133a and 134a, with optional rivet holes 163a and 163b, which align when the ends are joined and which receive a plastic rivet or the like (not shown) for holding the joined ends together. Each of these sections has a thumb screw 135. The split support pipe further includes a threaded nut 136, which is suitably secured in the pipe by a roll or spring pin 144, and which projects from the pipe's bottom end 137 so as to eliminate the need for a separate locking nut. Using this embodiment, installation of the support pipe is simplified as hereinafter described. Also, the split pipe advantageously allows the umbrella base to be used under tables that will not accommodate a long support pipe, and where the extra length of the support pipe is not needed. In these situations the top section of the support pipe is simply removed.
The body portion of this embodiment is similar to the previous embodiment. More specifically, a body portion in the form of housing assembly 139 has a lower ballast holding portion 140, and a top cover portion in the form of a cover plate 141 secured to the lower portion of the assembly by means of top screws 143. Advertising indicia, such as a company logo L, are provided on a separate billboard plate 145 having screw bosses 146 that fit into screw boss holes 176 in the cover plate 145, which is attached by screws 180. The lower portion of the housing assembly has outer perimeter sidewalls 147 and an inner wall structure 149 inside of the outer perimeter sidewalls. The inner wall structure 149 supports the cover plate 141 and the billboard plate 145 within the outer perimeter walls of the lower housing portion, and creates an interior compartment which is divided into four equal sized ballast cavities 151 by partition walls 153. The partition walls terminate at an center ring wall 155, which surrounds a central cylindrical retaining sleeve structure 157 that holds the split support pipe 132. Sleeve structure 157 having anti-rotating ribs 158 (seen in
It is noted that both cover plate 141 and billboard plate 145 of the housing assembly have turned-down perimeter edges 141a and 145a. In the case of the cover plate, these edges fit over the lower housing's inner wall structure as shown in
The inner wall structure and center ring wall of the lower housing of this embodiment effectively isolate the ballast compartments from the joints that occur between top cover plate and lower housing's perimeter sidewalls 147, and between the sleeve 157 and the center openings 152, 154 of the cover plate and billboard plate. It is at these joints that entry of moisture into the housing assembly is most likely to occur. The inner wall structure 149 creates a perimeter buffer space 159, and inner ring wall 155 creates interior buffer space 161. Drain holes, such as drain holes 165 and 167, are provided at the bottom of both of these buffer spaces to allow moisture collected in these spaces to drain from the housing assembly. Also, outside and inside O-rings 156, 160 can be provided on the underside of the housing cover in order to hermetically seal the ballast cavities. Sealing of these two parts can be accomplished in any number of ways known in the art, including using sealing compounds.
The corners of the lower housing are seen to have shoulder structures 169 that extend from angled corner portions 171 of the perimeter sidewalls. Each of the shoulder structures have a cam-screw opening 108a for receiving cam-screws 102, to which the support feet 103 are attached. The cam screws 102, support feet 103 and associated springs 106 of the support foot assemblies in this embodiment are identical to the cam screws, support feet and springs of the support foot assemblies in the embodiment shown in
To allow the ballast cavities 151 to be filled without removing cover plate 141, a ballast fill opening 175 is provided in the top cover plate of the housing above each of the ballast cavities. These openings each have an upwardly projecting collar 177 with and external thread and an associated internally threaded lid 179, which screws onto the collar. Thus, it is seen that ballast cavities can be filled by simply removing the billboard plate 145 and unscrewing lids 179. The billboard plate is secured to the top cover plate by screws 180, so removing the billboard plate will first require the removal of these screws, which insert from the bottom of the lower housing through screw openings 176 in the cover plate into screw bosses 146 on the bottom of the billboard plate.
As in the previous embodiments the top cover and bottom portions of the housing assembly, along with the billboard plate 145 and fill opening lids 179, can be suitably be fabricated as injection or structural foam molded polymer (e.g. HDPE or polypropylene) parts having high UV resistance.
Referring to
The base plate 183 of the umbrella base 181 is seen to include a flat billboard surface 187 surrounding pipe retaining sleeve 185 and support pipe 186, with advertising indicia in the form of a company logo L being provided on this surface about the pipe retaining sleeve. This logo will be readily visible to persons seated or standing near the umbrella supported by the base. The billboard surface can be provided directly on the top surface of base plate 183 or, as illustrated, by a thin billboard plate 189, which is placed on top of the base plate and which has a center opening 191 to accommodate the sleeve 186. The top of base plate is suitably provided with a shallow recess 193 to receive the billboard plate; preferably this recess has a depth that substantially corresponds with thickness of the billboard plate. This recess produces a raised perimeter rim 195 around the edges of the base plate that surrounds the billboard plate when the billboard plate is placed in the recess. If desired, separate attachments can be provided for the billboard plate, such as screw bosses on the bottom of the billboard plate and screw boss holes in the base plate similar to those described in the previous embodiment.
In both the
To provide an umbrella shaft holding structure for this embodiment, an upwardly projecting central sleeve 217 is integrally formed on the top wall of housing top 203 for receiving a split umbrella shaft support pipe 132 that is essentially identical to the split support pipe described above in connection with the embodiment of the invention shown in
In this embodiment, one or more ballast cavities 223 are formed underneath the housing assemblies housing top 203. The illustrated partition walls 225 formed on the underside of the housing top's top wall divides the interior compartment underneath the top wall into separate ballast cavities 223, which can be filled with a desired ballast material. Filling the ballast cavities is accomplished when the base is turned upside down by simply removing bottom cover plate 207 from the housing top 203, pouring the ballast in the ballast cavities, and replacing the bottom cover plate. The resulting weight of the base will depend on the type and amount ballast material used,
Both the housing top 203 with its integral sleeve structure 217, and the bottom cover plate 207 of the embodiment shown in
While the description above refers to particular embodiments of the present invention, it will be understood that many modifications may be made without departing from the spirit thereof. For example, the flat surfaces shown in the illustrated embodiments could be domed surfaces or surfaces of other shapes, so long as the surfaces are readily visible to persons within the vicinity of the umbrella base. The accompanying claims are intended to cover such modifications as would fall within the true scope and spirit of the present invention.
