Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
107 words
In an inflatable article made of impervious flexible material, a first member defining one mAin, generally plane, surface of the article and having an edge portion, and a second member defining another main, generally plane, surface of the article substantially parallel to said one main surface and having an edge portion, one of said first and second members having a given corresponding dimension larger than the corresponding dimension of the other member, and the edge portions of the first and second members together forming a peripheral lip which lies approximately in the said plane of the member having the smaller said dimension, when the article is inflated.
Claim 2
Dependent Claim
107 words
In an inflatable article made of impervious flexible material, a first member defining one mAin, generally plane, surface of the article and having an edge portion, and a second member defining another main, generally plane, surface of the article substantially parallel to said one main surface and having an edge portion, one of said first and second members having a given corresponding dimension larger than the corresponding dimension of the other member, and the edge portions of the first and second members together forming a peripheral lip which lies approximately in the said plane of the member having the smaller said dimension, when the article is inflated.
Claim 3
Dependent Claim
97 words
In an air mattress, a first member defining a generally plane surface intended for receiving a user and having an edge portion around its periphery, and a second member defining a generally plane under surface substantially parallel to the plane surface of the first member and having an edge portion around its periphery, said members being connected together at the edge portions to form a peripheral lip, and the first member having a smaller width than the second member so that said lip, when the mattress is inflated, lies substantially in the plane of the first member.
Claim 4
Dependent Claim
97 words
In an air mattress, a first member defining a generally plane surface intended for receiving a user and having an edge portion around its periphery, and a second member defining a generally plane under surface substantially parallel to the plane surface of the first member and having an edge portion around its periphery, said members being connected together at the edge portions to form a peripheral lip, and the first member having a smaller width than the second member so that said lip, when the mattress is inflated, lies substantially in the plane of the first member.
Claim 5
Dependent Claim
27 words
A mattress according to claim 2, comprising a folded strip having parts which are secured to the first and second members at the region of said lip.
Claim 6
Dependent Claim
70 words
A mattress according to claim 2, wherein at one corner of the mattress, that part of the second member which lies in the immediate vicinity of the lip is folded at the corresponding longitudinal edge and the fold thus formed is glued internally between lines formed by extensions of the lip of the transverse edge portion, the fold substantially compensating for the width differential between the first and second members.
Claim 7
Dependent Claim
88 words
A mattress according to claim 2, comprising a dividing wall which consists of an endless strip, edge portions of which form two marginal strips one of which marginal strips is glued along its length onto the entire free inner face of the interconnected first and second members, while the other marginal strip is folded and glued to the one marginal strip so that a joint is formed halfway up the dividing wall, said dividing wall serving to separate the mattress into a body part and a pillow part.
Claim 8
Dependent Claim
29 words
A mattress according to claim 5, wherein in the region of the dividing wall, the two parts of the folded strip are joined together to reinforce the peripheral lip.
Claim 9
Dependent Claim
53 words
A mattress according to claim 6, comprising a reinforcement for the connection between the first and second member provided by the outer marginal strip of the endless strip, the reinforcement having two parts which are connected to one of the first and second members and with an adjacent part of the endless strip.
Claim 10
Dependent Claim
41 words
A mattress according to claim 7, wherein the connection between the two superimposed ends which are glued to the inner peripheral strip is strengthened by a strip which forms a gusset which is connected to adjacent parts of the endless strip.
