Abstract
An umbrella includes a shaft with a cap connected thereto and a plurality of ribs are pivotally connected to the cap. A runner is movably mounted to the shaft and a plurality of stretchers are pivotally connected between the ribs and the runner. A top stop button and a lower stop button are respectively connected to the shaft. The ribs and the shaft are made of composite material and a reinforcement metal layer is coated on each of the ribs and the shaft.
Description
- The present invention relates to an umbrella and the frame of the umbrella is made of composite material with a metal layer coated thereon.
- A conventional umbrella is shown in FIG. 7 and generally includes a
shaft 31 has acap 41 connected to a top end thereof so thatribs 42 are pivotally connected to thecap 41 and a fabric is connected on theribs 42. Arunner 44 is movably mounted to theshaft 31 andmultiple stretchers 43 are pivotally connected between therubber 44 and theribs 42. Atop stop button 45 and alower stop button 46 are respectively connected to theshaft 31 so that when therunner 44 is pushed upward and is engaged with thetop stop button 45, thestretchers 43 are stretched and the umbrella is opened. When therunner 44 is pulled downward and engaged with thelower stop button 46, the umbrella is closed. In order to reduce the total weight of the umbrella, theribs 42 are made by composite material and thestretchers 43 are connected to theribs 42 by aconnection member 40 as shown in FIG. 8. However, the composite material maderibs 42 are easily broken by a bending force as shown in FIG. 9 and this could happen when the umbrella is used in a strong windy area. Besides, the fibers of the composite material could split off if the heat treatment of the parts is not well finished, the sharp and stiff fibers may hurt the users. - In accordance with one aspect of the present invention, there is provided a umbrella which comprises a shaft with a cap connected thereto and a plurality of ribs are pivotally connected to the cap. Each rib has a connection member connected thereto and a runner is movably mounted to the shaft. A plurality of stretchers are pivotally connected between the connection members and the runner. A top stop button and a lower stop button are respectively connected to the shaft, and the runner is engaged with one of the top stop button and the lower stop button. The ribs and the stretchers are made of composite material and a reinforcement metal layer is coated on each of the ribs and the stretchers.
- The primary object of the present invention is to provide a reinforcement metal layer coated on the frame of an umbrella so that the frame has better strength and is light in weight.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
- FIG. 1 is a side view to show the umbrella frame of the present invention;
- FIG. 2 is a flow chart to show the steps for forming the reinforcement metal layer on the frame;
- FIG. 3 is a cross sectional view to show the reinforcement metal layer on the frame;
- FIG. 4 is a cross sectional view to show that the reinforcement metal layer on a rib and a connection member is connected to the rib and a stretcher is connected to the connection member;
- FIG. 5 is a cross sectional view to show the runner mounted to the shaft and engaged with one of the top stop button and the lower step button;
- FIG. 6 shows that the ribs of the present invention have appropriate flexibility;
- FIG. 7 is a side view to show a conventional umbrella frame;
- FIG. 8 is a cross sectional view to show that conventional rib made of composite material and a connection member is connected to the rib and a stretcher is connected to the connection member, and
- FIG. 9 is a cross sectional view to show that conventional rib made of composite material as shown in FIG. 8 is broken.
- Referring to FIGS.1, the umbrella of the present invention comprises a
shaft 111 with acap 21 connected thereto and a plurality ofribs 22 pivotally connected to thecap 21. A fabric (not shown) is connected on theribs 22. Eachrib 22 has aconnection member 25 connected thereto as shown in FIG. 4 and eachconnection member 25 has a lug which is to be connected to astretcher 23. Arunner 24 is movably mounted to theshaft 11 and a plurality ofstretchers 23 are pivotally connected between the lugs of theconnection members 25 and therunner 24. A top stop button 110 and alower stop button 111 are respectively connected to theshaft 11. Referring to FIG. 5, therunner 24 is engaged with the top stop button 110 or thelower stop button 111 when the umbrella is opened or closed. - Referring to FIGS. 2 and 3, the
ribs 22 and theshaft 11 are made of composite material which can be carbon fibers or glass fibers and is heated to form thesolid ribs 22 and theshaft 11. Theshaft 11 and theribs 22 are made by thermosetting plastics or thermoplastics. Areinforcement metal layer 50/500 is coated on each of theribs 22 and/or theshaft 11. Thereinforcement metal layer 50/500 is formed by the following steps: - step 1: corroding an outer periphery of each of the
ribs 22 and thestretchers 23 to be a rough surface; - step 2: emerging the rough surface in a media chemical agent to form a bridging agent;
- step 3: plating a layer of nickel by way of chemical plating on the rough surface and the nickel is electricity productive, and
- step 4: coating a layer of metal on the nickel layer by way of anodic process or electroplating, for example.
- The metal layer can be copper, nickel, bronze, gold, black nickel and/or chrome. A transparent paint can also be coated directly on the layer of nickel.
- As shown in FIGS. 4 and 5, the
reinforcement metal layer 50/500 prevents the fibers of the composite material split out from theribs 22 and/or theshaft 11, and theconnection members 25 and therunner 24 will not scrape the surface of theribs 22 and/or theshaft 11. As shown in FIG. 6, the structural strength of theribs 22 is reinforced so that they has better flexibility and are not broken when theribs 22 are bent by strong wind. - While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
