Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments and accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.

The present invention will be described in detail with reference to the accompanying drawings.

The utility model provides a nunchakus, as shown in figure 1, the nunchakus comprises two nunchakus bodies 11 and a connecting rope 12 for connecting the two nunchakus bodies; wherein, the nunchakus also comprises a connecting part 13, the connecting part 13 is connected with a connecting rope 12, and the inside or the whole of the nunchakus body 11 is hollow so as to fixedly arrange the connecting part 13.

In the present embodiment, the material of the stick body 11 may be a relatively elastic and light material, such as hot melt adhesive (EVA), foam, rubber, or plastic. Therefore, the weight of the nunchakus is reduced, the nunchakus can be safely used, and the nunchakus can not be painful when being hit to the body part, so that the safety of a player, a body builder or a performer in competition, body building or performance is ensured.

In one embodiment of the present invention, the connecting portion 13 may be fixed in the stick body 11 by bonding. Fig. 2 is a schematic view of an embodiment of a connecting portion according to the present invention; fig. 3A and 3B are schematic cross-sectional views of the connecting portion according to the present invention.

As shown in fig. 2, 3A and 3B, the connecting portion 13 includes a connecting rod 21, and the outer surface of the connecting rod 21 is bonded to the hollow inner surface of the stick body 11; wherein the connecting rod 21 is hollow and has an upper port 22 and a lower port 23;

as shown in fig. 3A, the cross-sectional area of the lower port 23 is larger than the cross-sectional area of the upper port 22. Alternatively, as shown in fig. 3B, the cross-sectional area of the lower port 23 may be the same as the cross-sectional area of the upper port 22.

In this way, the connecting string 12 is connected to the connecting part 13 before the connecting part 13 is bonded to the hollow inner surface of the blade 11.

In an embodiment of the present invention, the connection may be performed by:

the connecting rope 12 is first threaded into the hollow connecting rod 21, threaded through the upper port 22 and threaded out of the lower port 23, and then the end of the connecting rope 12 can be knotted (not shown) outside the lower port 23, and the cross-sectional area of the knot can be smaller than that of the lower port 23 and larger than that of the upper port 22. Thus, when the connection cord 12 is pulled, the knot at the end of the connection cord 12 can enter the inside of the connection bar 21 through the lower port 23, and since the sectional area of the knot is larger than that of the upper port 22, the connection cord 12 is fixed in the connection bar 21 by the knot at the end, thereby connecting the connection cord 12 with the connection part 13, as shown in fig. 3A.

Or the connecting string 12 is connected to the connecting part 13 by tying the end of the connecting string 12 with a knot having a sectional area larger than that of the lower port 23, so that the connecting string 12 is fixed to the lower port 23 of the connecting rod 21 by the knot at the end, and the sectional area of the upper port 22 is arbitrary, and as shown in fig. 3B, the sectional area of the upper port 22 is equal to that of the lower port.

After the connecting cord 12 and the connecting portion 13 are connected, an adhesive may be applied to the outer surface of the connecting rod 21 of the connecting portion 13, and the connecting rod 21 coated with the adhesive may be inserted into the hollow stick body 11, thereby fixing the connecting portion 13 in the stick body 11 by the adhesive.

In the present embodiment, the outer surface of the connecting rod 21 may be a smooth surface, but the present invention is not limited to this, and in order to more firmly place the connecting rod 21 in the stick body 11, a groove may be provided in the outer surface of the connecting rod 21, so that an adhesive may be placed in the groove, and when the connecting rod 21 provided with the groove is inserted into the hollow stick body 11, the connecting part 13 may be more firmly fixed in the stick body 11 by the adhesive, and safety may be improved.

Fig. 4A and 4B are front and side views, respectively, of a slotted connection according to the present invention. Fig. 5 is a schematic view of another embodiment of a grooved connection according to the present invention.

As shown in fig. 4A and 4B, the groove 41 may be of a zigzag type, and the upper and lower ports of the connecting rod have the same sectional area. As shown in fig. 5, the groove 51 is of a spiral type. But is not limited thereto and may be of other types.

In addition, the connecting rod 21 may further include an elastic fixing member (not shown in the drawings) provided on an outer surface of the connecting rod 21; when the connection rod 21 with the elastic fixing member is inserted into the hollow portion of the stick body 11, the elastic fixing member is elastically adhered to the hollow inner surface of the stick body 11, and after the connection rod 21 is inserted, the elastic fixing member is firmly inserted into the inner wall of the stick body by its elasticity and is not pulled out because the stick body 11 is made of an elastic and light material such as EVA, foam, rubber, or plastic, thereby fixing the connection part 13 in the stick body 11. Wherein the elastic fixing part is a barb or the like.

In the present embodiment, the shape of the stick body 11 may be made into any shape as needed, and as shown in fig. 2 to 5, the stick body 11 has a cylindrical shape.

Fig. 6 is a schematic view of an embodiment of a stick body according to the present invention; fig. 7 is a schematic view of another embodiment of the stick according to the present invention.

As shown in FIG. 6, the shape of the stick body 11 near the distal end portion can be made into a gourd shape. As shown in FIG. 7, the proximal end portion of the shaft 11 may be shaped to have a curvature, such as a hemisphere or an ellipsoid. Therefore, on one hand, the interest of the user in the nunchakus can be increased, and on the other hand, the user can use the tail end to beat the shoulders, the back and the like of the user due to the fact that the tail end is made into the shape with a certain radian, and the function of massaging and body building can be achieved.

In this embodiment, each of the sticks 11 may have a length of 25 to 40cm, the weight of the nunchakus may be 80 to 300 g, and the length of the connecting string may be 12 to 20 cm. But not limited thereto, the above parameters may be adjusted according to actual needs.

Furthermore, in another embodiment of the present invention, the connecting portion 13 may only adopt a connecting rod and an elastic fixing member disposed on the outer surface of the connecting rod, so that the connecting portion 13 can be directly fixed in the stick body 11 through the elastic fixing member without using an adhesive for bonding, and the manufacturing and assembling are simple and convenient.

The utility model provides a nunchakus which is simple in manufacture, light in weight, high in safety and applicable to competitions, body-building and the like; wherein, the stick body 11 is made of elastic and light materials, which not only reduces the weight of the nunchakus, but also ensures the safety of users in competition and body building; the nunchakus can be made into any shape, thereby increasing the interest and having the function of health care massage.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above description is only the embodiments of the present invention, and is not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
