    • DETAILED DESCRIPTION OF THE INVENTION
  • Referring to the drawings and initially to FIGS. 1-4, an umbrella in accordance with the preferred embodiment of the present invention comprises an upper shank 4, a rib and canopy assembly 41 mounted on an upper end of the upper shank 4, an upper connecting tube 1 having an upper end mounted on a lower end of the upper shank 4, a lower shank 5 located under the upper shank 4, a lower connecting tube 2 having an upper end mounted on a lower end of the upper connecting tube 1 and a lower end mounted on an upper end of the lower shank 5, and a locking ring 3 mounted between the upper connecting tube 1 and the lower connecting tube 2 to lock the upper connecting tube 1 and the lower connecting tube 2. The upper end of the lower connecting tube 2 is secured to the lower end of the upper connecting tube 1 by a mortise and tenon engagement.
  • The upper end of the lower connecting tube 2 has an end face 20 formed with two radially opposite mortises 22. The end face 20 of the lower connecting tube 2 has a peripheral wall formed with an outer thread 21.
  • The lower end of the upper connecting tube 1 has an end face 10 rested on the end face 20 of the lower connecting tube 2 and formed with two radially opposite tenons 12 each inserted into a respective one of the mortises 22 of the lower connecting tube 2. The end face 10 of the upper connecting tube 1 has a peripheral wall formed with a catch flange 11 which is extended radially outward. The tenons 12 of the upper connecting tube 1 are formed on and protruded outward from the catch flange 11.
  • The locking ring 3 has an inner wall having an upper end formed with a stop flange 31 which is extended radially inward and rested on the catch flange 11 of the upper connecting tube 1 and a lower end formed with an inner thread 30 screwed onto the outer thread 21 of the lower connecting tube 2.
  • The upper shank 4 is made of a solid wooden tube. The lower end of the upper shank 4 is formed with a reduced post 40 inserted into the upper end of the upper connecting tube 1.
  • The lower shank 5 is made of a solid wooden tube. The upper end of the lower shank 5 is formed with a reduced post 50 inserted into the lower end of the lower connecting tube 2. Preferably, an aluminum tube 51 is mounted around the reduced post 50 of the lower shank 5 to reinforce the strength of the lower shank 5, and a screw 52 is extended through the aluminum tube 51 and partially inserted into the reduced post 50 of the lower shank 5 to combine the aluminum tube 51 and the lower shank 5. In addition, the screw 52 is partially extended through the reduced post 50 of the lower shank 5.
  • In assembly, referring to FIGS. 5 and 6 with reference to FIGS. 1-4, the upper connecting tube 1 is initially mounted on the upper shank 4, and the lower connecting tube 2 is initially mounted on the lower shank 5. Then, the tenons 12 of the upper connecting tube 1 are inserted into the mortises 22 of the lower connecting tube 2, so that the upper connecting tube 1 is connected with the lower connecting tube 2. Finally, the locking ring 3 is locked onto the lower connecting tube 2, with the inner thread 30 of the locking ring 3 being screwed onto the outer thread 21 of the lower connecting tube 2, so that the upper connecting tube 1 is closely connected with the lower connecting tube 2 by the locking ring 3. At this time, the stop flange 31 of the locking ring 3 is rested on the catch flange 11 of the upper connecting tube 1, and the tenons 12 of the upper connecting tube 1 are inserted into the mortises 22 of the lower connecting tube 2, so that the upper connecting tube 1 is connected with the lower connecting tube 2 rigidly and stably, thereby reinforcing the strength of the umbrella. Thus, the umbrella has a reinforced connecting structure.
  • Accordingly, the upper connecting tube 1 is initially locked on the lower connecting tube 2 by a mortise and tenon engagement, so that the umbrella is assembled easily and conveniently. In addition, the stop flange 31 of the locking ring 3 is rested on the catch flange 11 of the upper connecting tube 1, and the tenons 12 of the upper connecting tube 1 are inserted into the mortises 22 of the lower connecting tube 2, so that the upper connecting tube 1 is connected with the lower connecting tube 2 rigidly and stably, thereby greatly reinforcing the strength of the umbrella. Further, the stop flange 31 of the locking ring 3 is rested on the catch flange 11 of the upper connecting tube 1, thereby preventing the locking ring 3 from slipping downward. Further, the aluminum tube 51 is mounted around the reduced post 50 of the lower shank 5, so that the surface of the reduced post 50 of the lower shank 5 is smooth.
  • Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
