Abstract
Abstract A connector for corrugated materials includes a first member which has a base member which is held between a pair of panels of corrugated material and a projecting member which has a pair of apertures and which projects outwardly from a slot in one of the panels of corrugated material. A second member has a base plate which is held between a second pair of panels of corrugated material and a plurality of guide fingers some of which enter into the apertures of the first member and some of which enter these apertures and also hook onto the first member thereby locking the second pair of panels onto the first pair of panels. In order to provide additional engagement between the first and second members, the first member is provided with a pair of projecting plates which engage a pair of apertures on the second member when the first and the second members are connected.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
107 words
A connector for corrugated materials comprising a first member, with said first member comprising a base portion and a projecting member having at least one aperture and a second member with said second member having a base portion and projecting finger means projecting from said base member and proportioned to removeably project into said aperture of said first member thereby locking said first and said second members together, in which said projecting finger means comprises at least one cantilever flexible finger means and at least one cantilever rigid finger means lying in the same plane and with the flexible finger means pivotable transversely out of said plane.
Claim 2
Dependent Claim
107 words
A connector for corrugated materials comprising a first member, with said first member comprising a base portion and a projecting member having at least one aperture and a second member with said second member having a base portion and projecting finger means projecting from said base member and proportioned to removeably project into said aperture of said first member thereby locking said first and said second members together, in which said projecting finger means comprises at least one cantilever flexible finger means and at least one cantilever rigid finger means lying in the same plane and with the flexible finger means pivotable transversely out of said plane.
Claim 3
Dependent Claim
99 words
A connector for corrugated materials comprising a first member, with said first member comprising a base portion and a projecting member having at least one aperture and a second member with said second member having a base portion and projecting finger means projecting from said base portion and proportioned to removeably project into said aperture of said first member thereby locking said first and said second members together, in which said second member includes an aperture disposed proximate to said finger means with said aperture proportioned to receive said projecting member when first and said second members are engaged.
Claim 4
Dependent Claim
99 words
A connector for corrugated materials comprising a first member, with said first member comprising a base portion and a projecting member having at least one aperture and a second member with said second member having a base portion and projecting finger means projecting from said base portion and proportioned to removeably project into said aperture of said first member thereby locking said first and said second members together, in which said second member includes an aperture disposed proximate to said finger means with said aperture proportioned to receive said projecting member when first and said second members are engaged.
Claim 5
Dependent Claim
105 words
A connector for corrugated materials comprising a first member, with said first member comprising a base portion and a projecting member having at least one aperture and a second member with said second member having a base portion and projecting finger means projecting from said base portion in cantilever fashion and proportioned to removeably project into said aperture of said first member thereby locking said first and said second members together, with said projecting finger means comprising a pair of rigid finger means and a flexible finger means disposed between said rigid fingers, in the same plane thereof, and pivotable transverely out of said plane.
Claim 6
Dependent Claim
105 words
A connector for corrugated materials comprising a first member, with said first member comprising a base portion and a projecting member having at least one aperture and a second member with said second member having a base portion and projecting finger means projecting from said base portion in cantilever fashion and proportioned to removeably project into said aperture of said first member thereby locking said first and said second members together, with said projecting finger means comprising a pair of rigid finger means and a flexible finger means disposed between said rigid fingers, in the same plane thereof, and pivotable transverely out of said plane.
Claim 7
Dependent Claim
188 words
A connector for corrugated materials comprising a first member, with said first member comprising a base portion and a projecting member having at least one aperture and a second member with said second member having a base portion and projecting cantilever means projecting from said base portion and proportioned to removeably project into said aperture of said first member thereby locking said first and said second members together, with said first member including a pair of aligned apertures and with said second member comprising in one plane a first pair of rigid cantilever finger means and a first flexible cantilever finger means with said first pair of rigid finger means and said first flexible finger means capable of being recieved in a first of said apertures and with said second member further comprising in one plane a second pair of rigid cantilever finger means and a second flexible cantilever finger means with said second pair of rigid finger means and said second flexible finger means capable of being received in a second of said apertures and with said flexible finger means being pivotable transversely out of said planes.
Claim 8
Dependent Claim
188 words
A connector for corrugated materials comprising a first member, with said first member comprising a base portion and a projecting member having at least one aperture and a second member with said second member having a base portion and projecting cantilever means projecting from said base portion and proportioned to removeably project into said aperture of said first member thereby locking said first and said second members together, with said first member including a pair of aligned apertures and with said second member comprising in one plane a first pair of rigid cantilever finger means and a first flexible cantilever finger means with said first pair of rigid finger means and said first flexible finger means capable of being recieved in a first of said apertures and with said second member further comprising in one plane a second pair of rigid cantilever finger means and a second flexible cantilever finger means with said second pair of rigid finger means and said second flexible finger means capable of being received in a second of said apertures and with said flexible finger means being pivotable transversely out of said planes.
