Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
132 words
A kite comprising: a body of thin sheet material which is heat bondable without the introduction of a critical weakness in the material only with the application of a minimum amount of heat; a pair of structural members which are heat bondable only with the application of substantial heat which heat would introduce critical weakness into the body material if it were to be bonded directly to said structural members; said structural members having a bead of heat-responsive bondable material along one edge thereof, said bead material being heat bondable to said body material with the application of only such heat that it does not introduce a critical weakness in said body material; and said body being bonded to said structural members by bonding to said bead material on said structural members.
Claim 2
Dependent Claim
132 words
A kite comprising: a body of thin sheet material which is heat bondable without the introduction of a critical weakness in the material only with the application of a minimum amount of heat; a pair of structural members which are heat bondable only with the application of substantial heat which heat would introduce critical weakness into the body material if it were to be bonded directly to said structural members; said structural members having a bead of heat-responsive bondable material along one edge thereof, said bead material being heat bondable to said body material with the application of only such heat that it does not introduce a critical weakness in said body material; and said body being bonded to said structural members by bonding to said bead material on said structural members.
Claim 3
Dependent Claim
48 words
A kite according to claim 1, including: a pocket secured to each of said structural members; a cross brace adapted to have its ends engaged within said pockets to retain said structural members and said body in extended, kite flying position; and a keel secured to said body.
Claim 4
Dependent Claim
31 words
A kite according to claim 1, wherein: said body is a bondable polyvinylchloride; said structural members are a high density polyvinylchloride; and said bondable bead material is a low durometer polyvinylchloride.
Claim 5
Independent Claim
158 words
The method of making a kite, including the steps of: depositing a bead of heat-responsive bondable material along one side of structural members; positioning said structural members and a body of sheet material on a surface; said body material being heat bondable without the introduction of critical weakness only with the application of a minimum amount of heat and said structural members being bondable only with the application of an amount of heat which would introduce critical weakness in said body material; said bead of heat responsive bondable material being bonded to said structural members and bondable to said body material with a minimum amount of heat which does not introduce a critical weakness in said body material; heating said body material along all of its mating surfaces with said structural members to bond the body material to the structural members by effecting a bond to said heat-responsive bondable material; and removing the bonded structure from said surface.
Claim 6
Independent Claim
158 words
The method of making a kite, including the steps of: depositing a bead of heat-responsive bondable material along one side of structural members; positioning said structural members and a body of sheet material on a surface; said body material being heat bondable without the introduction of critical weakness only with the application of a minimum amount of heat and said structural members being bondable only with the application of an amount of heat which would introduce critical weakness in said body material; said bead of heat responsive bondable material being bonded to said structural members and bondable to said body material with a minimum amount of heat which does not introduce a critical weakness in said body material; heating said body material along all of its mating surfaces with said structural members to bond the body material to the structural members by effecting a bond to said heat-responsive bondable material; and removing the bonded structure from said surface.
Claim 7
Dependent Claim
40 words
The method of making a kite according to claim 4 wherein said heat-responsive bondable material is deposited along said structural members by dually extruding said structural members and said bondable material and cutting the composite structure into the desired lengths.
Claim 8
Dependent Claim
55 words
The method of making a kite according to claim 4 including placing a keel of bondable material on said surface in a preselected poSition with respect to said body material and heating said keel to effect a bond to said body material at the same time the body is being bonded to said structural members.
