DETAILED DESCRIPTION OF THE DRAWINGS

[0037] Referring to the drawings, an umbrella base according to the present invention is identified, generally, by reference number 10 and an umbrella for use with the umbrella base is identified by reference number 12. The umbrella includes a canopy 14 and post 16.

[0038] The umbrella base 10 comprises a top plate or deck 18, two end plate assemblies 20, two brace elements 22 and ballast elements 24.

[0039] The deck 18 has a top surface 24 and an opposing underside 26 and a return flange or skirt 28 extends along a periphery of the deck 18 towards the underside. Threaded fixing points 30 which serve as support formations for supporting the umbrella post 16 and four oversized fixing holes 32 for attaching the deck 18 to the end plate assemblies 20.

[0040] The deck 18 is shown rectangular in the illustrated embodiment of the invention and this is a cost-effective and practical shape, but the deck can have different shapes. The deck 18 is preferably formed from steel plate or other suitable durable metal, but it can potentially be made of other durable material. The terms top surface and underside are used herein with reference to the normal, upright orientation of the umbrella base 10 in use.

[0041] Each end plate assembly 20 includes an elongate end plate 34 with two opposing ends, two rotating castors 36 that are attached to the end plate at its opposing ends. Each end plate 34 is preferably recessed at its ends to accommodate most of the castor in the recess. Next to each recess there is a brace attachment formation in the form of a vertical bracing tab 38 with threaded holes and along an upper edge of the end plate 34 there is a flange 40 with threaded holes, to serve as a deck attachment formation.

[0042] Each end plate 34 includes a central cover plate section 42 and at the top of each of the castor recesses 44 there is a castor support plate 46 that is parallel to the flange 40 and the castor 36 is supported by the support plate 46 at a fixing point.

[0043] The two brace elements 22 each comprises a vertical flange 50 which has, on each extremity, two threaded fixing points 52 that align with the two holes on the bracing flanges 38 of the end plate assemblies 22 for attaching the ends of the brace elements to the end plate assemblies. Each brace element 22 also has a horizontal flange 48 that protrudes inwardly when the brace element is attached to the end plate assemblies 20.

[0044] The end plates 34 and L-profiled brace elements 22 are preferably also formed from steel plate.

[0045] When the brace elements 22 are attached to the end plate assemblies 20, they form a rectangular frame with the brace elements spaced apart and the end plate assemblies spaced apart and a central zone between them. The horizontal flanges 48 of the brace elements 22 form seat elements that protrude inwards towards the central zone. In other embodiments of the invention, the frame could include more or differently configured seat elements that protrude inwards to the central zone, from the brace elements 22 and/or the end plate assemblies 20. When the deck 18 is attached to the frame, it is spaced above these seat elements.

[0046] The umbrella base 10 include a ballast comprising one or more ballast elements 52 that are preferably in the form of one or more rectangular concrete slabs-preferably of a standard size that is readily available at stores and preferably have standard sizes. In the illustrated embodiment, the ballast elements 52 are a combination of 20040040 and 40040040 concrete paving slabs. The ballast elements 52 are supported on the horizontal flanges 48 or other seat protuberances, below the deck 18.

[0047] Referring to FIG. 4, the umbrella base 10 is transported in a flat pack kit form without the ballast elements 52, with the end plate assemblies 20 and the brace elements 22 stored on the underside of the deck 18, preferably in a space that is surrounded by the skirt 28 of the deck. The purpose of this invention is to provide a lightweight umbrella base that can be compactly and efficiently transported and delivered and this kit form serves that purpose.

[0048] Referring to FIGS. 5 to 9, the umbrella base 10 is assembled. Apart from providing a lightweight umbrella base that can be compactly and efficiently transported and delivered, the invention provides an umbrella base that, once delivered, can be easily assembled, including loaded with locally available, store-bought, paving slab ballast elements 52 and, on completion provide a compact and visually appealing fully mobile umbrella base 10.

[0049] FIG. 4 shows the flat-pack packaging configuration of the umbrella base 10, with the deck 18 upside-down and inside the deck, the two end plate assemblies 20 complete with castors 36 as well as the two brace elements 22. Also to be included are the necessary fixing and fastenings. This is the package that will arrive at the client, ready for assembly.

[0050] FIG. 5 shows the components for the assembly of the umbrella base 10 in exploded configuration with the store-bought ballast paving slabs 52, the end plate assemblies 20 shown in the upright position, the brace elements 22 either side and the deck 18.

[0051] FIG. 6 shows the start of the assembly process, with the first brace element 22 in position for attaching it to the end plate assemblies 20. The holes in the tabs 38 of the end plate assemblies 20 are aligned with the threaded fixing points 51 in the brace elements 22 and these are attached with bolts.

[0052] FIG. 7 shows the second brace element 22 attached similarly to FIG. 6 to provide the frame of the umbrella base 10.

[0053] FIG. 8 shows the store-bought paving slab ballast elements 52 loaded into the central zone of the completed frame with the deck 18 about to be attached.

[0054] FIG. 9 shows the deck 18 in position and attached to the frame with bolts through the oversized holes 32 and secured into the threaded fixing points on the flanges 40 of the end plates 34.

[0055] FIG. 10 shows the completed umbrella base 10 with the umbrella post 16 secured to the deck 18 with bolts securely bolted into the threaded holes 30 in the deck.

[0056] The assembly of the umbrella base 10 comprises these steps:

[0057] Before assembling the umbrella base 10, it will be necessary to procure the correct size and number of locally available paving slabs to serve as ballast elements 52.

[0058] Step 1 is to attach the brace elements 22 to the end plates 34 with all flanges 48 facing inwards. The fixing holes in the tabs 38 on the end plates 34 are aligned with and securely fixed to the fixing points 51 in the brace elements 22. The frame is now ready for loading with store-bought paving slabs 52.

[0059] Step 2 is to load the frame with the store-bought paving slabs 52.

[0060] Step 3 is to position the deck 18 and fix this to the end plate assemblies 20 through the oversized fixing point holes 32 in the corners of the top surface 24 with fasteners that are driven into the threaded holes in the flanges 40 of the end plate assemblies 20.

[0061] Step 4 is to attach the umbrella post 16 to the deck 18 by securing it into the post fixing points 30. In the illustrated embodiment there are four fixing points 30, but this may vary.

[0062] Step 5 is to attach the umbrella canopy 14 onto the post 16.

[0063] The umbrella 12 may be a cantilever umbrella, i.e. it may have an offset umbrella canopy, but the invention also works with umbrellas with central posts and different canopies.

[0064] The illustrated invention holds the following advantages: [0065] This system is easy to manufacture with no welded parts. [0066] It can be delivered in a compact box that can be carried by a single person. [0067] It is easy to assemble by 1 person. [0068] It is neat and attractive. [0069] Provides a ridged and stable structure for the umbrella. [0070] Once assembled, is easy to move as required.

[0071] In short, this invention is a high-tech, simple, easy to assemble base solution that is attractive and, extremely importantly, highly mobile.
