Abstract
Corrugated panels are intercoupled by a male and a female connector, each having a part received in its respective panel. The female connector has a U-shaped receiving volume, with a receiving slot in the front portion. The male connector has a pair of flanges connected by a rib. When assembled one flange is inserted in the receiving volume, and the rib is in the receiving slot. Two female connectors can be mated, by inverting one and inserting a part of its front portion into the receiving volume of the other female connector.
Claims8
A female connector for use with a corrugated material, comprising:
- a back portion having a thickness dimension suitable for insertion in the corrugated material;
- and
- a generally U-shaped receiving portion, extending outwardly from said back portion and defining a receiving slot therein, which receiving slot is open at the top and closed at the bottom, and the U-shaped receiving portion is uninterrupted except for the receiving slot, top and back portion.
A female connector for use with a corrugated material, comprising:
- a generally rectangular back portion having a thickness dimension suitable for insertion in the corrugated material, which back portion lies in a reference plane and has a thickness at least slightly less than the thickness of the corrugated material;
- and
- a generally U-shaped receiving portion, including a generally U-shaped wall portion extending substantially perpendicular to said back portion, and a front portion integral with and extending substantially perpendicular to said wall portion and parallel to the reference plane, which front portion defines a receiving slot and, with the wall portion, defines a receiving volume, said receiving slot being open at the top and closed at the bottom, and said wall and front portions being uninterrupted except for the receiving slot, top and back portion.
An assembly for intercoupling pieces of corrugated material, comprising:
- a female connector, including a back portion having a thickness dimension suitable for insertion in one piece of the corrugated material,
- a generally U-shaped receiving portion, extending outwardly from said back portion and defining a receiving slot therein, which receiving slot is open at the top and closed at the bottom;
- and
- a male connector, including
- first and second flange portions, spaced from each other,
- a rib portion interconnecting the flange portions, which rib portion has a thickness substantially smaller than the width of said flanges, and
- a leaf portion affixed to one of said flanges on the side opposite the side to which the rib is joined, which leaf portion extends substantially perpendicular to the flange for receipt in another piece of the corrugated material.
A male connector for use with a corrugated material, comprising:
- first and second flange portions, spaced from each other;
- a rib portion interconnecting the flange portions, which rib portion has a thickness substantially smaller than the width of said flanges;
- and
- a leaf portion, affixed to one of said flanges on the side opposite the side to which the rib is joined, which leaf portion extends substantially perpendicular to the flange for receipt in the corrugated material.
An assembly for intercoupling pieces of corrugated material, comprising:
- a first female connector, including a back portion having a thickness dimension suitable for insertion in one piece of the corrugated material, and a generally U-shaped receiving portion, extending outwardly from said back portion and defining a receiving slot therein, which receiving slot is open at the top and closed at the bottom, so that the U-shaped receiving portion is uninterrupted except for the receiving slot, top and back portion;
- and
- a second female connector, including a back portion having a thickness dimension suitable for insertion in another piece of the corrugated material, and
- a generally U-shaped receiving portion, extending outwardly from said back portion and defining a receiving slot therein, which receiving slot is open at the top and closed at the bottom, so that the U-shaped receiving portion is uninterrupted except for the receiving slot, top and back portion, such that an assembly is completed by inverting the second female connector and inserting a part of the second connector receiving portion into the U-shaped receiving portion of the first connector.
