BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an umbrella skeleton, and particularly relates to an umbrella skeleton that can be assembled by hand conveniently. [0003] 2. Description of Related Art [0004] At present, the conventional umbrella has an umbrella skeleton and a water repellent fabric, as shown in FIG. 5; the umbrella skeleton comprises a major shaft (40) and an umbrella frame (50). A handle (not numbered) is formed at a lower end of the major shaft (40), and a button (not numbered) is provided above the handle. The umbrella frame (50) has an upper runner (51), a middle runner (52), a lower runner (53) mounted encircling the major shaft (10), and multiple ribs (54), first stretchers (55) and second stretchers (56). The ribs (54) are attached to the upper runner (51) by a steel wire (57). The middle runner (52) is mounted below the upper runner (51) and one end of each of the first stretchers (55) is attached to the middle runner (52) by a steel wire (57), and the other end of each of the stretchers (55) is pivotally connected to the ribs (51) by a rivet. With the water repellent fabric fitted to the skeleton, the umbrella is assembled to provide shelter from sunshine or rain. Coil springs (58) are mounted around the major shaft (40). [0005] However, the conventional umbrella has some disadvantages [0006] 1. It is difficult to assemble: the ribs (54), the first stretchers (55), the second stretchers (56) are respectively fastened to the upper runner (51), the middle runner (52), and the lower runner (53) by the wires, and rivets are used for connecting the ribs (54), first and second stretchers (55,56), which is tedious and requires very nimble-fingered personnel. [0007] 2. Safety can not be ensured: distal ends of the iron wires are cut in manufacture which results in sharp tips that point outward, which is dangerous to the user. [0008] 3. Electroplating has pollution side effects: the iron wires require electroplating, which is toxic and causes environmental pollution. [0009] 4. Broken elements can not be replaced: once some elements of the umbrella are broken, it is virtually impossible for people to replace them without some special tools, and people normally throw away the whole umbrella, which is a waste of material. [0010] 5. Monotonous appearance of frame: For more than 100 years, umbrella frames have been either painted black or chromium plated steel. Ironically, despite huge variations in the appearance of the fabric, the user sees the frame rather than the fabric when the umbrella is actually in operation. [0011] 6. Corrosion: Despite electroplating of some components, inevitably the plating wears away after a certain amount of use of the umbrella, and, as the umbrella is commonly exposed to water, corrosion and seizing up of certain parts occurs. [0012] Therefore, the invention provides an umbrella skeleton to mitigate or obviate the aforementioned problems. SUMMARY OF THE INVENTION [0013] The main objective of the present invention is to provide an umbrella skeleton to assemble conveniently, and eliminate environmental pollution resulting from electroplating processes. [0014] The umbrella comprises a major shaft with a button provided in a lower part and an umbrella frame. [0015] The umbrella frame has a connection member, a sleeve, a middle runner, a spring, a lower runner, multiple ribs, and first and second stretchers. The umbrella skeleton of this invention includes beneficial points: [0016] 1. convenient to assemble: the ribs are inserted in the connection member, the first stretchers are connected between the middle runner and the ribs, and the second stretchers are connected between the lower runner and the first stretchers, which is convenient to assemble. [0017] 2. Safety is enhanced: as no iron wires and rivets are used, the umbrella will constitute no hazard to users. [0018] 3. No environment pollution: elements of the umbrella of this invention are made of plastic, so electroplating is not required, which eliminates the environmental pollution encountered with the prior art. [0019] 4. Easy to replace the elements: If some elements are broken, it is easy for user to replace it by hand, instead of throwing away the whole umbrella. [0020] 5. Variety of type and color can be applied: manufacturers may cater to the customers by changing the color or type of the skeleton, thus making the umbrella more pleasing to the eye. [0021] Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
