Abstract

Charm (1) for a chain (3) and/or ribbon and/or belt in the form of a necklace, a bracelet or the like, characterized in that this charm (1) is provided with a time-rendering device (2).

Description

The present invention concerns a charm for a chain, a chain and a chain element provided with such a charm.

In particular, the invention is intended for a chain in the form of a bracelet, a necklace or the like.

Such chains can be made of all sorts of materials such as for example metal, plastic, leather, wood, yarn or any other suitable material whatsoever.

Charms in the form of all sorts of figures and shapes with which a bracelet is given an exclusive and distinctive look and as a result of which said bracelet distinguishes itself from an ordinary bracelet without any charms, thus making the bracelet more unique to the user, are already known.

The known charms are made of stainless steel, silver, gold or the like, and they either or not make use of precious stones, fancy glass or wooden beads and the like having rather small dimensions, usually having a diameter smaller than 25 mm, preferably between 5 and 20 mm.

The above-mentioned charms enable the user to continuously change his/her looks by selecting charms and by providing them to a bracelet, a necklace or the like.

If the user wishes to do so, several charms according to different themes, in different materials, with different ornaments and the like can be provided to a single chain.

An example of such a chain with charms has been described in U.S. Pat. No. 7,007,507, whereby the chain is provided with means to restrict the movement of the provided charms, such that the charms do not gather around a single point of the chain, but remain nicely distributed over the chain.

These means can be made in all sorts of shapes and they are not only practical, but they can also confer additional character to the chain.

Charms which are fixed to the bracelet and which are hence selected by the manufacturer and not by the user are known as well.

When manufacturing such bracelets, a new charm or a new set of charms must be made for every new type of bracelet, which leads to relatively high production costs.

Further, it is known that people wearing a bracelet around one wrist, may wear a watch around the other wrist, which is disadvantageous in that the watch cannot be matched with the bracelet.

Another disadvantage is that the watch-strap cannot be easily replaced, such that it is not practical and moreover time-consuming to select a different watch-strap every day as a function of for example the clothes one is wearing or the activities one will carry out.

The present invention aims to remedy one or several of the above-mentioned and/or other disadvantages by providing a charm for a chain and/or ribbon and/or belt in the form of a necklace, a bracelet or the like, whereby the above-mentioned charm is provided with a time-rendering device.

In a practical embodiment of the invention, the charm is provided with a fixing element having an assembly opening, whereby the above-mentioned fixing element can be provided around the above-mentioned chain in a detachable or permanent manner by means of the above-mentioned assembly opening.

Naturally, charms which are provided with a time-rendering device can be assembled in many different ways.

However, there are five preferred embodiments of the invention, whereby the fixing element is formed of a threaded connection in the first embodiment, of an opening with internal screw thread in a second embodiment, of a hinged element in a third embodiment, of a permanent connection in a fourth embodiment, and of a hole with no hinge or no threaded connection in a fifth embodiment, which embodiments all provide a solution to one or several of the above-mentioned disadvantages.

The different assembly possibilities provide the user with an endless range of possible charms to choose from, provided with a time-rendering device, which are complementary to and can be added to other charms, as described above, and which are all attached to one and the same bracelet.

The user can express him/herself via these charms and change the looks, the color and the expression of the bracelet in a simple manner by means of the charms, either or not provided with a time-rendering device.

An advantage is that the charm is provided with a time-rendering device, and consequently functions as a watch, such that there is no need to wear a separate watch, which is cost-saving.

An additional advantage is that such a charm which is provided with a time-rendering device is easy to manufacture by producers of jewels and watches.

According to a preferred characteristic of the invention, the charm is provided with a fixing element with an assembly opening, and the above-mentioned fixing element is provided round the above-mentioned chain in a detachable manner by means of the above-mentioned assembly opening.

An advantage is that a charm which is provided with a time-rendering device, just like any other charm, can be easily replaced according to the user's taste, activities and the like.

An additional advantage is that every new type of charm which is provided with a time-rendering device can be fixed around an existing bracelet by means of the assembly opening, as a result of which the bracelets can be manufactured in larger series, leading to savings in the production costs.

The present invention concerns a chain formed of two chain elements which can be connected by means of a lock, whereby at least one of the above-mentioned chain elements is provided with a charm provided with a time-rendering device, whereby the charm can be connected to at least one other chain element in a permanent or detachable manner by means of connecting means provided to that end, whereby the above-mentioned connecting means are formed of an outside thread in the above-mentioned chain element and an opening with internal screw thread provided on the above-mentioned charm.

The present invention also concerns a chain element provided with a charm whereby the charm is provided with a time-rendering device and the chain element is provided with connecting means made in the shape of a threaded connection.

An advantage is that, as the chain has already been provided with a charm with a time-rendering device, the bracelet or the necklace is functional and thus costs can be saved.

An advantage is that the design of the chain allows for mass production of the chain elements, resulting in reduced production costs.

Another advantage is that the charm with the time-rendering device can be easily produced in different variants and that the user can provide one or several of said charms to the chain as desired, depending on his/her preferences, activities or the like.

According to a preferred characteristic of the invention, the above-mentioned arm 15 is provided with locking means 18 which can lock the arm 15 in the closed position.

These locking means 18 are preferably made as a leaf spring 19 provided on the above-mentioned arm 15 and extending with one part 20 past the free end of said arm 15.

On the above-mentioned part 20 of the leaf spring 19 is provided a lip 21 which can work in conjunction with an edge 22 which in this case has been provided on a second protruding element 23 at the bottom of the time-rendering device 2.

The lip 21 of the above-mentioned leaf spring 19 will preferably mesh behind the above-mentioned edge 22 as the arm 15 moves from the open into the closed position.

The method for applying a charm 1 according to the invention to a chain 3 is very simple and as follows.

In the position represented in FIG. 4, the arm 15 of the charm 1, which is provided with a time-rendering device 2, is turned clockwise around the hinge point 16, such that the chain 3 can be provided in the assembly opening 8.

When the chain 3 has been provided in the opening 8, the arm 15 can be put in the closed position again by making the arm 15 turn anti-clockwise around the hinge point 16.

When the arm 15 is almost in the closed position, the lip 21 of the leaf spring 19 will reach the edge 22 of the above-mentioned charm 1 and, as a result, it will be pushed in the direction of the chain 3, and as the arm 15 is rotated further around the hinge point 16, the lip 21 will mesh behind said edge 22, after which the arm 15 will be situated in the above-mentioned closed position.

In order to remove the above-mentioned charm 1, the user will exert a force on the far end of the arm 15 according to arrow P in FIG. 4, as a result of which the lip 21 can no longer mesh behind the edge 22 on the charm 1 and the arm 15 can be turned clockwise around the hinge point 16, such that the fixing element 7 can be put in the open 30 position and the chain 3 can be simply removed from the assembly opening 8.
