Description

FIELD OF THE INVENTION

The present invention relates generally to a button assembly for buttoning an article of clothing. Specifically the present invention relates to a button assembly having pivotable button head pivotably mounted to a base.

BACKGROUND OF THE INVENTION

Buttons are used for fastening an article of clothing. For instance it is commonly known to sew a plurality of buttons onto a coat. The buttons are aligned to engage corresponding buttonholes so as to allow the coat to be fastened. Accordingly buttons are preferably mounted onto an article of clothing such that the button may be manipulated and inserted into a corresponding buttonhole of an article of clothing. However, the threads may wear over time as the button is subject to twisting and turning when inserted into the buttonhole. Thus, sewn buttons tend to fall off after a period of time.

It is also known to use mechanical devices to button an article of clothing together. For instance one such device disclosed in U.S. Pat. No. 3,705,443 to Camporese. The '433 patent discloses a button assembly including a base, an elongated shaft, and a button head. The elongated shaft has a pointed end which is operable to engage a receiving portion of the button head. However such configuration does not allow the button head to rotate in three-dimensional space about the shaft. Thus, the pointed end of the shaft is placed through a buttonhole and the button head is mounted thereon. Naturally, the button head may be separated from the base and thus render the device inoperable.

Accordingly it is desirable to have a button assembly wherein the button head is able to rotate in all directions so as to accommodate the insertion of the button head into a buttonhole. It is further desirable to have a button assembly wherein the button head is retained onto the base so that the two pieces remain together thus mitigating the chances of losing one piece and rendering the device inoperable.

SUMMARY OF THE INVENTION AND ADVANTAGES

A button assembly including a button head having a mounting portion and an elongated shaft attached to a base is provided. The button assembly includes a bearing member disposed on one end of the shaft. The bearing member is configured to fittingly engage the mounting portion of the button head so as to pivotably attach the button head to the shaft. The base may be inserted into an article of clothing in alignment with a corresponding buttonhole. Accordingly the user is able to rotate and pivot the button head about the bearing member of the shaft so as to facilitate the insertion of the button head into the buttonhole.
