ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a clasp device, and more particularly to a clasp device for fabrics, films, and sheet materials.
2. Description of the Prior Art
A typical clasp device for clasping fabrics, films and sheet materials are disclosed in U.S. Pat. No. 5,046,222 to Byers et al. and comprise a body having a rounded opening formed therein and defined by a frame section for receiving a button member. The button member includes an annular groove defined between a pair of annular walls; in which one of the annular walls should be engaged through the frame section together with the sheet material by force. Children and women may not easily engage the button member into the frame second of the body.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional clasp devices for sheet materials.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a clasp device for allowing the fabrics, films and sheet materials to be easily clasped in place by children and women.
In accordance with one aspect of the invention, there is provided a clasp device for clasping a sheet material, the clasp device comprising a frame including an opening formed therein and including a notch formed therein and communicating with the opening for increasing a size of the opening, a button including a body having a size for engaging in the opening of the frame, the body including an annular flange extended radially outward therefrom and having a size greater than the opening of the frame for engaging with the frame and for preventing the button from being disengaged from the frame, and the frame including at least one stop extended therefrom and engaged with the annular flange of the button for securing the button to the frame and for preventing the but ton from being disengaged from the frame.
The frame includes an inner peripheral surface for defining the opening thereof, and includes at least one depression formed in the inner peripheral surface thereof for receiving the sheet material when the sheet material is engaged between the button and the frame.
The frame includes a peripheral shoulder formed therein and communicating with the opening of the frame for receiving the annular flange of the button. The frame includes a serrated peripheral surface formed therein for defining the annular shoulder of the frame and for engaging with the sheet material when the sheet material is engaged between the annular flange of the button and the frame.
The frame includes an upper surface and includes at least one bulge extended upward beyond the upper surface of the frame, the stop of the frame is extended from the bulge of the frame for engaging with the annular flange of the button.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
