Abstract
In a product for sheltering an individual or individuals from sun, rain, wind or snow, it is known to have a central support shaft for carrying and manipulating the said product. In this invention a significant improvement is made to the structure of the product rendering it superior to existing patented inventions. The improvement consists of an organization of the primary structural elements of the portable shelter in a manner and according to the consideration of formulae that results in a stable product having an eccentric location of the support shaft relative to the central portion of the sheltered field of occupancy. This new composition takes the plan from of a square geometry with chamfered corners. This configuration permits the engagement of two products in twin-performance by use of a snap-on gutter attachment. This double composition permits user advantage during certain spectator-orientated stationary application. The inventive and creative ideas embodied in this invention offer the user/users occupancy of the zone of maximum protection.
Description
This invention consists of a portable shelter from weather elements of which the coaxaportent parts are organized and balanced according to a series of considerations that result principally in the eccentricity of the sheltering fabric relative to its support shaft.
~~
It is common that uTnbr llas have their sheltering fabric disposed in a simple geometry that features a central and axial support shaft. This curtently conventional and familiar model imposes a limitation on its use in chat the principal support shaft itself occupies the zone that is offered the greatest potential degree of shelter by the sheltering fabric.
This results in a reduced scope of applications and offers the user inereased exposure to the elements from which the fabric is intended to shelter.
s~
This invention reorganizes the prixlcipal components of the common umbrella ancl Hdcls constituents to enhance the latter's performance. The new product is charac[erizecl principally by the remote disposition of the heart of the sheltercd zone relative t(i the axis -I-~- ~~5 e Canade ~e~ d0 2008112124 1 I ~

of the streactzu-al support shaft.
The new,product allows the user/users to occupy the zone of maxfmum potentisl protection. Further, since the sheltering fabric is not concentric about the support, the user can benefit from the variations in the location of the concentrated shelter zone that are offered by simple manual rotation of tl~ saipp.oitshaft.
The structure and fabric of the pmducts may consist of natural or man-made materials.
Conventionally-available uaaterials may be selected according to their strength, flexibility, weight, and density. Governing formulae establish and appropriateness of selected materials with the scale of a particular model, and further, their relaeionsWps with the other components. For example to achieve axial balance the moment forces must neutralize about the support shaft; thus the following formula applies:
LiZxWi lnzxWz (I,, ami LZ are measures of spoke cumponenGs;
W, and WZ are the respective weights per unit of ineasure; see figure 3) Similar formulae would govern the various component relationships.

The skeleton frame of the structure is of dynamic quality with the two pri,ncipal postures beinig "open" or "closed". The strat network is of rigid components that fold at single pin joints; or of collapsable components similarly attached. Depending on the scale of the prodact model both designs may also be included in a single composition.
Thi,s iu,vention operates as a personal shelter from weather elements or as a coIIective sheltar, say in the case of a sunsbade to be used on a beach. It may be carcied by the user or it may attach to 4nd shelter a cbair, baby-carriage or a set of golf clubs. The "flat-edge" of the geometry of the sheltering fabric also permits the use of two or more products in concert with each otfier. The units would engage with a snap-on "gutter" and perform as a shelter of greater accommodation. This approach would enbance the use of the product during less dynamic application such as sheltering statiottary spectators, sheltering two candidates during a relatively slow promenade, sheltering individuals on a beach, etc.
In any aud all applications advantage can be derived from ecce.ntricity of the support shaft relative to the sheltering fabric.

In drawings which illustratc the embodiment of the invention, Figure 1 is a top (plan) view; Figure 2 is an elevation referenced to Figure 1; Figure 3 is a section referenced to Figure 1; Figure 4 represents perspectives of various views of the invention.
',-Figure 5 is a 3D CAD image of the inventl.on, text-referenced_ J~ .
The plan configuration (Figure 1) consists of a square with chamfered corners.
The support shaft is located on a principal diagonal axis such that dimension "A"
is greater in measure than dimension "B". A/B is not a constaztt, but a ratio that varies according to related design speciCics. Eight fabric-support spokes radiate symmetrically about the i f principal axis (plan) from the shaft axis (vertical) to the determined extremities. The sheltering fabric conforms to the shape defined by the radiating spokes.
The principal components of a typical elevation (Figure 2) consasr of the dominaxnt volume that the fabric defines when applied with lizxx.ited tensiota to the structural spokes.
This volume is dressed witit a partial-perimeter skirt. The skirt is tapered to allow that -4-it's bottom edge remains normal to the vertical support shaft.
The vettical surfaces of the skirt serve to reduce the torsion forces that may be imposed on the shaft by a cross wind. These fozces arc neutmlized by the counter force of the wind pushing on the face of the sldrt; which face is broader to the side of the shaft that has less surface of sheltering fabric.
This horizontal edge also offers a stabilizing reference to the peripheral view of the user when the apparatus is carried in its upright position. The skirt may be fit with an opening at the diagonal corner which would reinforee the stabilizing features and enhauce the user's comfort by offering an orientation marker as a beacon to the short span of the composition.
. . .
Figtire 2 includes an illustration of the optional rain gutter for twin use of the product.
This component would be of the same material (rip-stop nylon or similar) as the sheltering fabric and would adhere to the two umbrellas by means of conventional attacliment snapror similar means.
In section, (Figure 3) the structural components derive from those of a conventional umbrella. The composition is not reliant on unique dxmensions, but rathw benofizs from the variety offered by the intexrelations of its constituent components and the selection of materials available for the fabrication.
