Abstract
A fastening device and method thereof is described. According to an embodiment of the present invention there is a fastening device comprising an insertion component and a receptacle component. The insertion component and the receptacle component, each includes a barbed outer surface. The insertion component comprises two sections of its barbed outer surface, separated by a flange, such that one section of the insertion components is configured to be inserted inside the receptacle component. A method of fastening a first substrate to a second substrate using a fastening device according to an embodiment is provided comprising pushing the insertion component into a hole in the first substrate, pushing the receptacle component into a hole in the second substrate, and pushing the insertion component into the receptacle component.
Claims20
A fastening device comprising:
- an insertion component and a receptacle component;
- the insertion component having
- a cylindrical body with two sections, with a first barbed surface along an outer perimeter of the first section and a second barbed surface along an outer perimeter of the second section, the two sections divided by a flange;
- and
- the receptacle component having
- a cylindrical body having a receptacle barbed surface along its outer perimeter;
- an internal ledge;
- and
- an inner diameter for receiving the second section of the insertion component, the inner diameter after the internal ledge being constant in diameter along an entire length of the second barbed surface of the second section;
- wherein the second barbed surface of the second section configured to be pushed into the receptacle such that each of a plurality of surface layers of the second barbed surface moves past the internal ledge of the receptacle component for complete engagement, such that an upper surface of the receptacle component rests against a bottom surface of the flange.
A fastening device comprising:
- an insertion component and a receptacle component;
- the insertion component having
- a shaft with two sections, with a first barbed surface along an outer perimeter of the first section and a second barbed surface along an outer perimeter of the second section, the two sections divided by a spacer;
- and
- the receptacle component having
- a body having a barbed surface along its outer perimeter;
- an internal ledge;
- and
- an inner diameter for receiving the second section of the insertion component, the inner diameter after the internal ledge being constant in diameter along an entire length of the second barbed surface of the second section ;
- wherein the second barbed surface of the second section configured to be manually pushed into the receptacle such that each of a plurality of successive barb layers of the second barbed surface moves past the internal ledge of the receptacle component, such that an upper surface of the receptacle component rests against a bottom surface of the spacer.
A method of fastening a first substrate to a second substrate using a fastening device,
- the fastening device comprising an insertion component and a receptacle component;
- the insertion component having
- a shaft with two sections, with a first barbed surface along an outer perimeter of the first section and a second barbed surface along an outer perimeter of the second section, the two sections divided by a flange;
- and
- the receptacle component having
- a body having a receptacle barbed surface along its outer perimeter, similar to the first barbed surface;
- an internal ledge;
- and
- an inner diameter for receiving the second section of the insertion component, the inner diameter after the internal ledge being constant in diameter along an entire length of the second barbed surface of the second section;
- and
- the method comprising,
- pushing the first section of the insertion component into a hole in the first substrate, the flange and the second section configured to remain outside the hole in the first substrate,
- pushing the receptacle component into a hole in the second substrate, and
- engaging the second section into the inner diameter of the receptacle component, such that each of a plurality of surface layers of the second barbed surface is configured to collapse, moving past the internal ledge of the receptacle component, and unfolds, until an upper surface of the receptacle component rests against a bottom surface of the flange.
