Description:

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a necklace/bracelet connector, and more particularly to an improved necklace/bracelet connector for easily and quickly connecting both ends of a necklace or a bracelet, and users can change a chain with a new chain or a chain of other material or color, or replace a pendant by their bare hands.

2. Description of the Related Art

Referring to FIG. 4 for the prior art necklace/bracelet connector 2, a loop 22 is extended from the rear end of an axial barrel 21. At the stage of shaping the finished product, the axial barrel 21 is stamped into a C-shape and inserted into both ends 41, 42 of a chain 4, and then stamped into a narrower and flatter form as shown in FIG. 5 by a punching machine, so that the axial barrel 21 is clamped by both ends 41, 42 of the chain 4 to complete the secured connection of the necklace/bracelet connector 2 and both ends 41, 42 of the chain 4. Basically, such prior art necklace/bracelet connector 2 is fixed to both ends 41, 42 of the chain 4 properly by a stamping process to prevent them from being loosened from each other. However, an insecure connection may be resulted from a fast mass production process or an operator's negligence, and consumers will complain about the damage of the necklace or bracelet. After the necklace/bracelet connector is connected to a chain 4 with a surface made of a smooth material (such as a plastic thread, strand, or string, etc), instant glue is usually applied to make sure of a secured connection, and thus complicating the manufacturing process and increasing the manufacturing cost. Particularly, after a necklace/bracelet connector 2 of this kind is connected to both ends 41, 42 of a chain 4, the chain 4 of other material or color, or another new chain 4 cannot be changed, and the pendant of other model cannot be changed either, and thus causing tremendous inconvenience to consumers.

In view of the foregoing shortcomings of a traditional necklace/bracelet connector 2 that is connected to both ends 41, 42 of a chain 4, manufacturers recently developed a necklace/bracelet connector 3 as shown in FIG. 6. Although this kind of necklace/bracelet connector 3 also comprises a loop 32 extended from the rear end of an axial barrel 31, the axial barrel 31 is a spring barrel made by densely wrapping a wire 310, and the loop 32 is the final winding of the spring barrel and parallel to the axis of the spring barrel. When this necklace/bracelet connector 3 is connected to both ends 41, 42 of a chain 4, both ends 41, 42 of the chain 4 are passed through the barrel from the front end of the axial barrel 31, and then a small portion 311 of the end of the first winding of wire is folded or bent to press both ends 41, 42 of the chain 4 (as shown in FIG. 7) to complete the connection between the necklace/bracelet connector 3 and both ends 41, 42 of the chain 4. The connection between this recently improved necklace/bracelet connector 3 and both ends 41, 42 of a chain 4 is more secured and thus will not be loosened or damaged easily. However, after the necklace/bracelet connector 3 is connected to a chain 4, consumers cannot change a new chain 4 or a chain of color material or color by their bare hands, and also cannot change a pendant of a different model. Thus, such improved necklace/bracelet connector 3 is still inconvenient.

SUMMARY OF THE INVENTION

In view of the foregoing shortcomings of the prior art necklace/bracelet connector 2 and the recently improved necklace/bracelet connector 3, the inventor of the present invention invented and developed an improved necklace/bracelet connector that is easy-to-install, secured, and consumers can change a new chain or a chain of other material or color by their bare hands, or change a pendant of a different model.

Therefore, it is a primary objective of the present invention to provide a necklace/bracelet connector that can directly pass both ends of a chain in a direction from the front to the rear through the barrel of an axial barrel and then bend the ends into 180 degrees to insert the ends back into the barrel without a stamping process or using an adhesive for a secured connection.

Another objective of the present invention is to provide a necklace/bracelet connector that allows consumers to change a new chain or a chair of other material or color, or change a pendant of a different model by bare hands.

To achieve the foregoing two objectives, a necklace/bracelet connector of the present invention comprises a loop extended from the rear end of an axial barrel, and a circular hole disposed at the front end of the axial barrel, and the width of the rear end is substantially corresponsive to the circular hole, and the length of the circular hole is at least 1.4 times of the long circular hole, elliptic hole, or an “8”-shaped hole to define a flared barrel with a smaller front portion and a larger rear portion. Both ends of a chain are passed in a direction from the front to the rear through the barrel, and then bent 180 degrees and finally inserted back into the barrel without a stamping or adhering process, so as to change a new chain or a chain made of another material or with a different color (such as plastic thread, strand, string, and leather string) or change a pendant with another one with a different model in a convenient and quick manner by bare hands.

The necklace/bracelet connector according to another preferred embodiment comprises a female necklace/bracelet connector and a male necklace/bracelet connector connected with each other, wherein the female necklace/bracelet connector comprises an axial barrel, a sleeve extended from a rear end of the axial barrel, and a sphere fixed onto an external sidewall of the sleeve; and the male necklace/bracelet connector comprises an axial barrel, an insert extended from a rear end of the axial barrel, a cylinder fixed onto the axial barrel; and a snap-in rod being substantially Y-shaped and having a closed end and pivotally connected to the cylinder, such that the insert of the male necklace/bracelet connector can be inserted correspondingly into the sleeve of the female necklace/bracelet connector to directly connecting the female and male necklace/bracelet connectors with each other, and the Y-shaped snap-in rod having an opening with a closed end on the male necklace/bracelet connector is latched to a sphere on the sleeve of the female necklace/bracelet connector, so as to connect the male and female necklace/bracelet connectors and maintain their fixed connection.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The structural assembly, technical measures, and functions of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings.

Referring to FIGS. 1, 2 and 3, a necklace/bracelet connector 1 comprises a loop 12 extended from the rear end of an axial barrel 11, and the axial barrel 11 at its front end includes a circular hole 111 (as shown in FIG. 2), and its rear end has a width substantially corresponding to the circular hole, and the length corresponds to a long circular hole 112, an elliptic hole, or an “8”-shaped hole (as shown in FIG. 3) which is at least 1.4 times of the circular hole to produce a flared barrel 110 with a smaller front portion and a larger rear portion, and both ends 41, 42 of a chain 4 are passed through the barrel 110 in a direction from the front to the rear, and then bent 180 degrees and inserted back into the barrel 110 (as shown in the left cross section of FIG. 1) without using a stamping or adhering process. Users can change a chain 4 with a new chain 4 or a chain 4 of other material or color (including a plastic thread, a strand, a string, and a leather cord).

If it is necessary to remove a chain 4 connected to the necklace/bracelet connector 1 of the invention, a user just needs to hold and push the chain 4 in a direction as shown in Arrow “A”, so that the chain 4 can be moved towards the loop 12 and the 180-degree bent portion 43 of the chain 4 can be moved out of the external side of a long circular hole 112 of the flared barrel 110 to quickly resume the 180-degree bent portion 43 back into a linear form, and the chain 4 is drawn out in a direction opposite to the direction indicated by Arrow “A”, so as to remove the chain 4 from the necklace/bracelet connector I of the invention. The procedure is very simple and quick, and thus users can change a chain 4 with a new chain 4 or a chain 4 of other material or color (including a plastic thread, a strand, a string, and a leather cord) by their bare hands. Regardless of the material or color of the chain 4, the chain 4 usually has a pendant (not shown in the figure). If the connector connecting both ends of the necklace adopts the necklace/bracelet connector 1 of the invention, then the pendant of a different model can be changed by removing the necklace/bracelet connector 1 at an end of the chain 4. The removal and reinstallation are the same as those for removing and installing the chain 4, whose procedure is also simple and quick, and thus will not described further here.

Referring to FIGS. 3˜1 and 3˜2 for the top view and the cross-sectional view of a necklace/bracelet connector according to another preferred embodiment of the present invention, the necklace/bracelet connector includes a female necklace/bracelet connector la and a male necklace/bracelet 1b, wherein the female necklace/bracelet connector 1a is comprised of a sleeve 13 extended from a rear end of an axial barrel 11, and the male necklace/bracelet connector 1b is comprised of an insert 14 extended from a rear end of the axial barrel 11. In the meantime, the insert 14 of the male necklace/bracelet connector lb is inserted correspondingly into the sleeve 13 of the necklace/bracelet connector la to connect the female and male necklace/bracelet connectors 1a, 1b with each other. Further, the shape and structure of the axial barrel 11 of the female and male necklace/bracelet connectors 1a, 1b are identical to those of the axial barrel of the necklace/bracelet connector 1 as illustrated in FIG. 1. A front end of the axial barrel 11 includes a circular hole 111 (as shown in FIG. 2), and the width of a rear end of the axial barrel 11 the is substantially equal to the circular hole 111, but the length is at least 1.4 times of a circular hole 111, a long circular hole 112, an elliptic hole, or an 8-shaped hole (as shown in FIG. 8). Similarly, both ends 41, 42 of a chain 4 are passed through its cylinder 110 in a direction from the front to the back of each axial barrel 111 of the female and male necklace/bracelet connector 1a, 1b, and then bent 180 degrees and inserted into each cylinder 110 for securely connecting both ends 41, 42. Like the necklace/bracelet connector 1 as illustrated in FIG. 1, no stamping or adhering process is needed.

Referring to FIGS. 3˜1 and 3˜2 for the necklace/bracelet connector according to a preferred embodiment of the present invention, the necklace/bracelet connector is designed into a female necklace/bracelet connector la and a male necklace/bracelet connector 1b for connecting both ends 41, 42 of a chain 4 and then directly connecting the male and female necklace/bracelet connectors 1a, 1b without using a movable buckle or S-shaped connecting hook. To assure and maintain the fixed connection of the female and male necklace/bracelet connectors 1a, 1b and prevent them from being loosened or fallen out, a sphere 15 or a raised point is soldered onto an external sidewall of the sleeve 13 of the female necklace/bracelet connector 1a. In the meantime, a cylinder 16 or a ring is soldered and transversally disposed on the axial barrel 11 of the necklace/bracelet connector 1b, and pivotally installed to a snap-in rod 17 which is substantially Y-shaped and has an opening with a closed end.

When the female and male necklace/bracelet connectors 1a, 1b according to a preferred embodiment of the present invention are inserted and coupled to both ends 41, 42 of a chain 4, the insert 14 disposed at a rear end of the male necklace/bracelet connector lb is inserted directly into the sleeve 13 disposed at a rear end of the female necklace/bracelet connector la for connecting the female and male necklace/bracelet connectors 1a, 1b without using a movable buckle or S-shaped connecting hook. In the meantime, the Y-shaped snap-in rod 17 having an opening with a closed end and disposed on the male necklace/bracelet connector 1b is latched onto a sphere 15 disposed on the female necklace/bracelet connector la for connecting and fixing the female and male necklace/bracelet connectors 1a, 1b and maintaining their fixed connection. Further, the female and male necklace/bracelet connectors 1a, 1b can be separately easily by lifting up the rear end of the snap-in rod 17 along the direction indicated by the arrow A of FIG. 3˜2 to a position indicated by an imaginary line, so as to pull the insert 14 out from the sleeve 13. Therefore, the necklace/bracelet connector can be installed or separated easily and quickly.
