    Detail Description of Preferred Embodiment
  • Referring to the drawings, the significant difference of the adjustable tension type of sunshade awning of the present invention from the sunshade awning of the prior art in which the tarpaulin is fixed by means of the lateral poles is that the structural frame and the tarpaulin are attached with each other in tension by means of the steel cable and the stretching device, so that the sunshade awning of the present invention has the characteristics of simple structure and good integration.
  • The adjustable tension type of sunshade awning comprises standing poles 1, standing pole bases 2, top poles 4 and tarpaulin 5, wherein standing pole bases 2 are attached to standing poles 1, each of four top poles 4 is attached to center joint 6 at one end and to standing pole 1 at the other end so as to form the structural frame, the stretching device is provided at the end of top pole 4 at which top pole 4 is attached to standing pole 1, the stretching device is provided with a latch hook, steel cable 14 passing through the hemmed edge of tarpaulin 5 is tied on these latch hooks, and tarpaulin 5 is attached and fixed to the structural frame by means of steel cable 14 and the latch hooks at the corners.
  • The stretching device comprises stopping block 10, sleeve 7, plugging end 3, sliding block 9, and locking screw 8, wherein stopping block 10 is fixed in top pole 4 with the thread formed therein, plugging end 3 is fixed to the outer end of sleeve 7, sleeve 7 is clearance-fitted in top pole 4 with a longitudinal groove formed in its lower wall, sliding block 9 is fixed in top pole 4 and fitted to the longitudinal groove of sleeve 7, locking screw 8 is engaged with the thread of stopping block 10 at its inward end and inserted into a hole of plugging end 3 at its outward end, an annular groove is formed in locking screw 8, the head of fixing bolt 11 of plugging end which passes through plugging end 3 is engaged with the annular groove so as to form the structure where locking screw 8 can be attached movably to plugging end 3, a hexagon-socket is formed on the outward end of locking screw 8 and a latch hook is formed in plugging end 3.
  • When the stretching device is used, locking screw 8 is wrenched with the hex wrench which is mated with the hexagon-socket while the head of fixing bolt 11 of plugging end which passes through plugging end 3 is engaged with the annular groove, stopping block 10 is fixed to top pole 4 and can not be moved, and sliding block 9 is fixed to top pole 4 and fitted to the longitudinal groove, therefore, sleeve 7 can not rotate, and locking screw 8 is forced to move outwardly, making sleeve 7 with plugging end 3 move outwardly also, so that tarpaulin 5 is stretched by steel cable 14 which is tied on the latch hook of plugging end and pulled tautly in opposite direction so as to achieve the final object. The adjustment scope for stretching tarpaulin 5 depends on the length of the longitudinal groove in the lower wall of sleeve 7.
  • While the preferred embodiment of the present invention is described hereinbefore, it is apparent for those skilled in the art to make variations and modifications without departure from the principle of the present invention, and the variations and modifications still belong to the scope of the present invention for which protection is sought.
