Self detachable sinker assembly for fishing
FIELD OF THE INVENTION 
     The present invention relates to a sinker assembly for use in fishing, and more particularly to a self-detachable sinker assembly which can be grouped together one by one in a cluster manner. Each sinker of the present invention is wrapped by a buckle belt which can be releasably tightened to hold the sinker in place. Once the sinker assembly of the present invention got stuck by underwater obstacles, such as rocks and plants, it is very easy to save the fishing lines as well as the fishing hooks only by letting go of the sinkers contained in the buckle belts one by one as long as the pull force on the fishing line is large enough to render the buckled belts open. 
     Fishing has been a worldwide popular outdoors sport. Various fishing tackles are adopted to meet different fishing requirements. Some people engage in their fishing along river banks, and some prefer to do it by the coastal area. Naturally, the fishing equipment are various according to the respective fishing conditions. 
     However, many fishing people no matter where they fish have often confronted themselves with the same problem wherein their fishing sinkers get stuck by underwater obstacles such as rocks or plants. To escape from these embarrassing situations, most people will exert force on the fishing lines, trying to pull the stuck sinkers out of the obstacles, thus resulting in the breaking of the fishing rods or loss of fishing hooks. 
     SUMMARY OF THE PRESENT INVENTION 
     Therefore, the primary object of the present invention is to provide a self detachable sinker assembly including a releasable buckle belt as well as a sinker which is wrapped by the flexible buckle belt in use so that the stuck fishing lines and hooks can be readily freed at the expense of the detachable sinkers. 
     One further object of the present invention is to provide a self detachable sinker assembly which can be which can be separably grouped together one by one in a cluster so that fishing people can constitute a combined sinker of different weight by means of a single type sinker.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     As shown in FIG. 1, a conventional fishing line 2 is provided with at the end thereof a sinker 23 having a through hole right at the central portion thereof for the passage of the fishing line 2 and a connection loop 21 is located right under the sinker 23 with a pair of fishing hooks 22 coupled thereto. 
     Referring to FIG. 2, the self detachable sinker assembly of the present invention mainly comprises a flexible buckle belt 6 and a oval-shaped sinker 5 that are integrally put together as one unit. Moreover, the sinker assembly can be grouped together in consecutive order in a cluster manner. 
     The sinker 5 is provided with a longitudinal through hole 51 at the center thereof with a longitudinal groove 52 disposed at the middle of the top and bottom surfaces thereof respectively. 
     The flexible buckle belt 6 is produced in integral form and is able to be resiliently bent to wrap the sinker 5 within a loop formed by buckling the two ends of the buckle belt 6 together. On the right end of the buckle belt 6 are disposed four protruding buckle members 62 in operative engagement with a number of corresponding buckle holes 64 disposed at the opposite end of the buckle belt 6, in such a manner that the buckle belt 6 can be joined end to end to form a loop to accommodate the sinker 52 therein. 
     To group a number of sinkers 5 together in a cluster, the present buckle belt 6 is also provided with, on the same surface as the buckle members located, a pair of L-shaped attachment hooks 63 at the middle point thereof and a pair of spaced attachment blocks 61 with the buckle holes 64 disposed therebetween. Along the axial direction, each attachment block 61 is provided with a through hole 611 in which the L-shaped hook members 63 of another buckle belt 6 can be engaged to group the so fixed sinkers 5 together in a cluster as shown in FIG. 7. 
     In assembly, the buckle belt 6 is engaged in the grooves 52 of the sinker 5 with the two ends thereof overlapped and buckled together by way of the buckle members 62 as well the corresponding buckle holes 64 so that the sinker 5 is tightly wrapped and fixed in place by the belt 6 as shown in FIGS. 3 and 4. Furthermore, to group a number of so fixed sinkers together, as shown in FIG. 7 and FIG. 8, the L-shaped hook members 63 disposed at the bottom surface of a buckled belt 6 are engaged with attachment blocks 61 of another buckle belt 6. Thereby a number of sinkers 5 can be readily grouped together as one desires. 
     As shown in FIG. 5 and FIG. 8, the fishing line 2 is led through the through holes 611 of the attachment blocks 61 of the buckle belt 6 in association with the topmost sinker of the cluster of sinkers, and the fishing hooks are then attached at the terminal of fishing line 2. 
     Referring to FIG. 2, the protruding buckle members 62 as well as the L-shaped hook members 63 all terminate in bulged ends so that they can firmly engage in their respective holes 64 and 611 in assembly. 
     In practical use, the grouped sinkers 5 are in association with fishing hooks with the number thereof variable by proper attachment. Once the sinkers get stuck by rocks or underwater plants, the fishing person can pull the fishing line hard thereby the force will render the buckled belt 6 to open as shown in FIG. 8, permitting the wrapped sinkers 5 to get free one by one so that the stuck fishing line can be freed from the obstacles, such as rocks and underwater plants, without causing much damage to the fishing line and hooks.
