US 12,551,814 B1 · Fasteners for foam construction elements

Abstract

Fastener for foam construction elements such as logs, includes an elongate body and a central longitudinally extending axis. The body has first and second elongate parts, and a head connected to one end of each elongate part and which is biased when in a rest state of the body in which it has a width larger than an aperture of the foam construction elements to prevent passage therethrough. The first and second parts are movable relative to one another to change a width of the head to be smaller than the aperture of the foam construction elements to enable its insertion through such apertures. A flange at an opposite end of each elongate part projects outward from the central axis of the body and in combination have a width larger than the aperture of the foam construction elements to prevent passage therethrough, and thereby secure adjacent foam construction elements together.

Dependent claims

A fastener for foam construction elements, comprising:

an elongate body having a first end, a second end opposite to said first end, and a central longitudinally extending axis,
said body comprising:
a first elongate part having a first end and a second end opposite the first end;
a second elongate part having a first end and a second end opposite the first end;
a head connected to said first end of said first elongate part and said first end of said second elongate part, said head being biased when in a rest state of said body to have a width that is larger than a width of said head when said body is not in the rest state, said first and second parts being movable relative to one another to change the width of said head;
and
a flange at said second end of each of said first and second parts, said flanges projecting outward from the central axis of said body;
and
hinge means between said first and second parts and defining a pivot axis in a longitudinal direction for enabling said first and second parts to pivot about said pivot axis to thereby reduce the width of said head.

A fastener for foam construction elements, comprising:

an elongate body having a first end, a second end opposite to said first end, and a central longitudinally extending axis,
said body comprising:
a first elongate part having a first end and a second end opposite the first end;
a second elongate part having a first end and a second end opposite the first end;
a head connected to said first end of said first elongate part and said first end of said second elongate part, said head being biased when in a rest state of said body to have a width that is larger than a width of said head when said body is not in the rest state, said first and second parts being movable relative to one another to change the width of said head;
and
a flange at said second end of each of said first and second parts, said flanges projecting outward from the central axis of said body;
and
wherein said first part comprises a longitudinally extending wall and a pair of spaced apart guide walls extending inward from peripheral edges of said wall of said first part, said second part comprising a longitudinally extending wall and a rib extending inward from said wall of said second part apart from peripheral edges of said wall of said second part, said rib being configured to lie between said guide walls when said walls of said first and second parts are adjacent one another, said first and second parts being movable relative to one another when said walls of said first and second parts are adjacent one another to cause said head to change its width.
