DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to the drawings, an umbrella, in accordance with the invention, is designated generally by the reference numeral 10. The umbrella 10 comprises an umbrella pole 12, a fixed umbrella hub 14 in accordance with the invention, which is fixed to an upper end of the umbrella pole; a movable umbrella hub 16 in accordance with the invention, which is slidable along the umbrella pole; a number of umbrella frame members in the form of four ribs 18 and four spreaders 20. The ribs 18 are pivotally and releasably connected to the fixed hub 14 and the spreaders are each pivotally connected at one end, to the ribs 18 and pivotally and releasably connected at an opposite end, to the movable hub 16. The ribs 18 support a canopy 22. Inner end portions of the ribs 18 and the spreaders 20 have transversely extending hinge pins 21 which provide for hinged connection of the ribs 18 and the spreaders 20 to the fixed umbrella hub 14 and the moveable umbrella hub 16, respectively.
The umbrella 10 is of the larger type such as a market umbrella, wherein the canopy and the frame members are relatively heavy. As such, the umbrella hubs 14 and 16 are required to support the weight of the canopy and the frame members when the umbrella is deployed and also need to be sufficiently strong to bear a full range of operational loads which typically are much higher than the weight of the components of the umbrella. More specifically, the hubs 14 and 16 are required to be sufficiently strong and durable so as to support wind loads on the umbrella in windy conditions. Furthermore, the hubs 14 and 16 are required to have sufficient strength to bear the stresses and forces which are exerted on the umbrella during deployment of the umbrella into its open configuration as shown in Figure 1 .
The fixed umbrella hub 14 comprises three steel plates comprising a central disc 24, an upper retention disc 26 and a lower retention disc 28 which are releasably fastened together by means of bolts 30.
The central disc 24 defines a central bore 32 which is configured to receive the umbrella pole 12. The central disc has an upper flat abutment face 34 and a lower flat abutment face 36 and defines an outer periphery 38. Furthermore, the central disc 24 defines four outer radial slots 40 which extend inwardly from the outer periphery. The central disc further defines a number of discontinuous perpendicular slots 42 which each intersect and extend perpendicularly with respect to a different one of the radial slots 40. The central disc 24 has an inner periphery 44 which defines the central bore 32. The central disc also defines four inner radial slots 46 which extend inwardly from the inner periphery 44. The upper retention disc 26 is of the same radius as the central disc 26 and defines a central bore 48 which is configured to receive the umbrella pole 12. The upper retention disc 26 has a flat abutment face 50 on an underside thereof and defines an outer periphery 52. The upper retention disc 48 further defines four radial slots 54 which extend inwardly from the outer periphery.
The lower retention disc 28 is of the same radius as the central disc 26 and defines a central bore 56 which is configured to receive the umbrella pole 12. The lower retention disc 28 has a flat abutment face 62 on an upper side thereof and defines an outer periphery 58. The lower retention disc 28 defines four radial slots 60 which extend inwardly from the outer periphery.
The three discs 24, 26 and 28 are fastened to one another by means of the bolts 30 so that in their assembled condition, the disc 24 is located between the upper and lower retention discs 26 and 28. The slots 54 of the upper retention disc 26 and the slots 60 of the lower retention disc 28 are dimensioned and configured so as to be in register with the outer radial slots 40 of the central disc 24 so as to receive end regions of the ribs 18 within the slots in register, in an arrangement permitting hinged displacement of the ribs 18 relative to the hub 14. In order to connect the ribs 18 to the hub 14, the end portions of the ribs are located in the outer radial slots 40, with the hinge pins thereof being located within the perpendicular slots 42. Thereafter, the upper and lower retention discs are fastened to the central disc by means of the bolts 30 such that the upper and lower retention discs overlie the perpendicular slots 42 thereby capturing the hinge pins 21 of the ribs 18 within the perpendicular slots. In the assembled condition of the hub 14, the abutment face 36 of the upper retention disc abuts the upper abutment face 34 of the central disc 24 and the abutment face 62 of the lower retention disc 28 abuts the lower abutment face 50 of the central disc thereby providing a secure unitary attachment structure for the ribs of the umbrella.
The fixed hub 14 is releasably secured to the umbrella pole by means of securing pins 62 which are located in the inner radial slots 46 of the central disc and which project inwardly therefrom into the central bore 32 thereby to extend into spaced holes provided therefor along the circumference of the umbrella pole 12 such that the securing pins 62 extend into the holes in the umbrella pole, thereby fixing the central disc to the umbrella pole. In the assembled condition of the hub 14, with the upper and lower retention discs bolted to the central disc, the securing pins 62 are captured in the inner radial slots thus providing for fixing of the hub 14 to the umbrella pole.
The moveable umbrella hub 16 comprises three steel plates comprising a central disc 124, an upper retention disc 26 and a lower retention disc 28. The upper and lower retention discs 26 and 24 are the same as the upper and lower retention discs 26 and 28 of the fixed umbrella hub 14. The central disc 124 is similar to the central disc 24 of the fixed hub 14, with the only differences being that the central disc 124 of the moveable hub 16 does not include the inner radial slots 46 and defines a central bore 132 which has a slightly larger diameter than the diameter of the central bore 32 of the disc 24 so as to provide for sliding displacement of the central disc relative to the umbrella pole 12. In the drawings, those features of the discs of the moveable hub 16 which are the same and/or similar to those features of the discs of the fixed hub 14, are designated by the same and/or similar reference numerals.
The spreaders 20 are releasably and hingedly connected to the hub 16 in the same manner as the ribs 18 are connected to the hub 14 as described hereinabove. The Applicant envisages that a buffering device may be inserted into the central bore 132 of the central disc to act between the hub 16 and the umbrella pole so as to provide smooth sliding displacement of the hub relative to the umbrella pole.
The hubs 14 and 16 when assembled, from homogeneous unitary structures that are both strong and durable and therefore particularly suitable for use with larger umbrellas. The Applicant envisages that the discs of the hubs may be of a non-corrosive steel such as a carbon and chromium-containing alloy steel. Furthermore, the thickness of the discs is such that the hubs when assembled have the necessary strength to bear the operational loads to which umbrellas incorporating the hubs are subjected in use. In this regard, the flat abutment faces of the discs provide large abutment surfaces having sufficient surface area to spread and transfer loads acting on the hubs throughout the structures of the assembled hubs thus relieving concentrations of stresses and forces acting on the hubs.
The configuration of the discs and the manner in which the discs are fastened to one another to form a unitary hub, allows for ease of disassembly and assembly for maintenance purposes.
An important advantage of the configuration of the discs is ease of manufacture in that the discs can be manufactured using a simple, inexpensive cutting operation and a relatively small amount of material. More specifically, the plates can be manufactured by simply cutting out the shapes in a laser cutting or metal cutting or punching operation using a press tool. The configuration of the discs thus provides for the mass production of umbrella hubs. It also allows the manufacture of hubs for umbrellas having "nonstandard" shapes which are not commonly produced in large numbers, wherein the outer radial slots can be cut in the discs so as to accommodate different numbers of ribs and spreaders and also to cater for different spacial configurations of the ribs and spreaders by cutting the slots in different positions.
A further important advantage of the umbrella hubs is that the configuration of the discs allows the discs to be assembled quickly with relative ease and without any fabrication to produce the hubs.
