Description:
FIELD OF THE INVENTION 
     This invention relates to an umbrella and an umbrella frame. More particularly, the present application involves an umbrella frame comprising of a post, arms, modular connectors, a lift ring and a locking element wherein the post, arms, modular connectors may be rigid multiple spaced multiple wires. 
     BACKGROUND OF THE INVENTION 
     Umbrellas are widely used for personal or garden protection. There are a variety of umbrellas available in the market which are used to protect a user from rain, sun and and/or wind. An umbrella is basically made up of a frame and a fabric cover fixed to the top section of an umbrella. A basic umbrella frame essentially comprises of a rigid shaft and a plurality of ribs or spokes attached to the top of the central shaft. There is a movable element provided along the central rigid shaft for moving up and down to facilitate the opening and closing of the umbrella. 
     In the umbrella system retail market, umbrellas are categorized on the basis of their size, durability, maintainability and mechanical strength. These are the important parameters to determine an umbrella&#39;s suitability for use in a particular environment and for a particular customer. 
     There have been reported numerous cases where the umbrella structure has collapsed or broken due to use over time or in extreme and challenging environments. For example, umbrellas can be damaged by severe and unexpected weather and strong winds, which can cause component parts of the umbrella frame to become cracked or bent. Others suffer damage as a result of improper handling, such as while transporting them from one location to another quickly or recklessly and/or as a result of improper installation. Many of the umbrellas known in the art suffer the disadvantages of not being able to withstand strong winds or other harsh weather, as well as not being capable of simple repair when damage does occur. Such cases happen due to the use of downgrade material in umbrella manufacture and more importantly due to faulty umbrella designs which have relatively weaker mechanical strength. 
     Henceforth, the strength of the umbrella frame is of much importance to a user, since in extreme wind conditions or other scenarios where the strength of the umbrella frame is to be tested a stronger and mechanically stable umbrella assembly provides a better service to the end user and a longer operational life. There have been a number of attempts to increase the strength of an umbrella frame by using reinforcements, accessories along the ribs or spokes to provide a stronger system. However, much has not been achieved since the use of additional parts have resulted in increase of weight, complex design and made the umbrella less desirable to be used frequently. 
     Thus, there exists a need for an umbrella frame having a strong and stable mechanical assembly which can provide to the user complete value and satisfaction with an efficient and longer operational life.

     The present invention is directed to an umbrella, and more particularly to an umbrella frame assembly. While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail at least one specific embodiment, with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiment or embodiments illustrated. 
     With reference to  FIGS. 1-18 , an umbrella frame assembly  10  is illustrated. As shown in  FIG. 2A  the umbrella frame  10  comprises of a post  20  having a top end  20   a  and a bottom end  20   b . As illustrated the post  20  is made up of four wires  2   a ,  2   b ,  2   c  and  2   d . The wires  2   a  and  2   b  are made of a single half-bent wire  2   ab  whereas the wires  2   c  and  2   d  are made up of another half-bent wire  2   cd.    
     In an embodiment of the invention the four wires  2   a ,  2   b ,  2   c  and  2   d  can be separate independent wires. 
     In another embodiment of the invention, the post  20  can be made up of any number of wires. 
     In yet another embodiment of the invention, the post  20  can be a tubular shaped body. 
     The wires  2   a ,  2   b ,  2   c  and  2   d  are bound to each other by four spacers  3   a ,  3   b ,  3   c  and  3   d  located near the top end  20   a  of the post  20 .

       FIG. 19  depicts a spring lock mechanism in an alternative embodiment of the present invention. The wire  2   a  is pressed inwardly to create a locking bend  2   ax  which permits the ring  4  to slip over the locking bend and to retain the ring  4  in the upward position. 
     In yet another embodiment of the invention, multiple wires may include the spring lock structure of locking bend to retain the ring  4  in an upward position. 
     In yet another embodiment of the invention, the bending or twisting of the wire  2   a  can be done in any suitable shape or form to retain the ring  4 . 
     With reference to  FIG. 20A  and  FIG. 20B  another modified spring lock structure is discussed. As shown in  FIG. 20A  the spring lock assembly  20  comprises of a twisted wire  20   a  which is fixed to the wire  2   a  at location X. The spring lock assembly  20  can be fixed at location X by means of welding or any other joining method like use of fasteners, screw etc. The ring  4  is located at an upward position with respect to the spring lock assembly  20  in  FIG. 20A . The fixation of lock assembly  20  at location X on the wire  2   a  permits the lock assembly  20  to move inwardly and outwardly with respect to the wire  2   a . When it is desired to bring the ring  4  to a downward position the lock assembly  20  can be pressed inwards to come closer to the wire  2   a  and the ring  4  is passed over it and moved to a downwards position as shown in  FIG. 20B . 
     In yet another embodiment of the invention, the spring lock assembly  20  can be attached to multiple wires of the umbrella frame. 
     The use of spacers in the present invention to join the plurality of wires in the post, arms and the modular connectors is of exemplary significance. The structure of the spacers between the plurality of wires for the post, arms and modular connectors provides additional strength against bending at a lower weight and mass of a solid member of the same outside dimensions. The application of spacers as a reinforcement member is being put to model use in the present invention and the increase in mechanical strength and stability provided to each component i.e. the post, arms and modular connectors with the use of spacers yields visible results and benefits. Thus, the spacers are an essential and necessary element of the present invention. 
     The umbrella frame  10  has the advantages of being easily assembled and manufactured. The locking mechanism used in the umbrella is relatively easy and the complete structure is lightweight and strong. The umbrella frame  10  lends greater strength and stability to the umbrella which increases its life and also its usage in extreme and challenging weather conditions. The umbrella can be easily closed by sliding down the lift ring  4  along the post  10  which reduces it space occupation while not in use. Further, the assembled wires can be replaced or fixed with ease, if incase any repair is required to the umbrella frame  10 . 
     The umbrella frame  10  can be used in a variety of applications. This umbrella frame can be used in the day-to-day hand umbrella and the large, standing outdoor umbrellas which are commonly utilized at restaurants, bars, hotels, and other places that offer outdoor seating so as to shield people from the sun, as well as from other elements of nature, such as wind, light rain, etc. The umbrella frame can be built for small, medium as well as large sized umbrellas and sizes can range from 12 inches to 9 feet in diameter. The umbrella frame lends flexibility and rigidity to the umbrella structure and hence proves to be a better design. 
     The rigidity and density of all the parts of the umbrella frame  10  can be tempered for a desired flexibility as needed. The post, arms, lift ring and modular connectors may be comprised of metal, wood or fiberglass but not limited to these rigid compositions. Thermoplastic materials can also be used to fabricate the umbrella frame as they offer a degree of flexibility in the members of the umbrella frame. These plastics have a degree of flexibility, and distribute the impact energy on the frame through all of the plastic components of the umbrella. This increases the life of the umbrella frame  10  which is generally the more costly portion of an umbrella unit. The other materials of the wires used in making the post and the arms can be but not limited to wooden dowels, bamboo, small rigid tubing, PVC (Polyvinyl chloride), plastic etc.
