Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 235 words
An improved mattress support structure of the type having a mattress on the mattress support with an opening defined therein and a receptacle mounted on the mattress support in a position below the opening in the mattress, wherein the improvement comprises: a parting web associated with the structure and mattress, said parting web being anchored at one end to the mattress support; moveable positioning means securing the other end of said parting web, the parting web extending from said one end thereof onto said positioning means; power means to move the positioning means associated with said parting web from a first position wherein the mattress is in a relaxed condition to a second position where the parting web forces the walls of the mattress away from each other to define an enlarged opening in the mattress; and closure means operatively associated with the moveable positioning means and extending over and closing the receptacle top in one position with the mattress opening closed and extending away from and opening the receptacle top in a second position when the mattress opening is enlarged, said closure means including a cover element slideably mounted on the receptacle and operatively associated with the power means, said cover element sliding over and closing the receptacle top in one position with the mattress closed and sliding away from and opening the top in a second position when the mattress opening is enlarged.
Claim 2
Dependent Claim 235 words
An improved mattress support structure of the type having a mattress on the mattress support with an opening defined therein and a receptacle mounted on the mattress support in a position below the opening in the mattress, wherein the improvement comprises: a parting web associated with the structure and mattress, said parting web being anchored at one end to the mattress support; moveable positioning means securing the other end of said parting web, the parting web extending from said one end thereof onto said positioning means; power means to move the positioning means associated with said parting web from a first position wherein the mattress is in a relaxed condition to a second position where the parting web forces the walls of the mattress away from each other to define an enlarged opening in the mattress; and closure means operatively associated with the moveable positioning means and extending over and closing the receptacle top in one position with the mattress opening closed and extending away from and opening the receptacle top in a second position when the mattress opening is enlarged, said closure means including a cover element slideably mounted on the receptacle and operatively associated with the power means, said cover element sliding over and closing the receptacle top in one position with the mattress closed and sliding away from and opening the top in a second position when the mattress opening is enlarged.
Claim 3
Dependent Claim 66 words
An improved mattress support structure as recited in claim 1, wherein said closure means includes a cover element pivotally mounted to said receptacle and operatively associated with said shaft, said cover element sliding over and closing the receptacle top in one position with the mattress opening closed and sliding away from and opening the receptacle top in a second position when the mattress opening is enlarged.
Claim 4
Dependent Claim 62 words
The structure of claim 1, wherein said closure means includes a cover element pivotally mounted to the mattress support and operatively associated with said shaft, said cover element sliding over and closing the receptacle top in one position with the mattress opening closed and sliding away from and opening the receptacle top in a second position when the mattress opening is enlarged.
Claim 5
Dependent Claim 233 words
An improved mattress support structure of the type having a mattress on the mattress support with an opening defined therein and a receptacle mounted on the mattress support in a position below the mattress opening, the improvement comprising: a parting web associated with the structure and mattress, said parting web being anchored at one end to the mattress support; moveable positioning means securing the other end of said parting web, the web extending from said one end thereof onto said positioning means; power means to move the positioning means associated with said parting web from a first position where the mattress is in a relaxed condition to a second position where the web forces the walls of the opening of the mattress away from each other to define an enlarged opening in the mattress; and closure means operatively associated with said web and extending over and closing the receptacle top in one position with the mattress opening closed and extending away from and opening the receptacle top in a second position when the mattress opening is enlarged, said closure means including a cover element slideably mounted on the receptacle and operatively associated with the power means, the cover element sliding over and closing the receptacle top in one position with the mattress opening closed and sliding away from and opening the receptacle top in a second position when the mattress opening is enlarged.
Claim 6
Dependent Claim 233 words
An improved mattress support structure of the type having a mattress on the mattress support with an opening defined therein and a receptacle mounted on the mattress support in a position below the mattress opening, the improvement comprising: a parting web associated with the structure and mattress, said parting web being anchored at one end to the mattress support; moveable positioning means securing the other end of said parting web, the web extending from said one end thereof onto said positioning means; power means to move the positioning means associated with said parting web from a first position where the mattress is in a relaxed condition to a second position where the web forces the walls of the opening of the mattress away from each other to define an enlarged opening in the mattress; and closure means operatively associated with said web and extending over and closing the receptacle top in one position with the mattress opening closed and extending away from and opening the receptacle top in a second position when the mattress opening is enlarged, said closure means including a cover element slideably mounted on the receptacle and operatively associated with the power means, the cover element sliding over and closing the receptacle top in one position with the mattress opening closed and sliding away from and opening the receptacle top in a second position when the mattress opening is enlarged.
Claim 7
Dependent Claim 66 words
An improved mattress support structure as recited in claim 4, wherein said closure means includes a cover element pivotally mounted to said receptacle and operatively associated with said shaft, said cover element sliding over and closing the receptacle top in one position with the mattress opening closed and sliding away from and opening the receptacle top in a second position when the mattress opening is enlarged.
Claim 8
Dependent Claim 62 words
The structure of claim 4, wherein said closure means includes a cover element pivotally mounted to the mattress support and operatively associated with said shaft, said cover element sliding over and closing the receptacle top in one position with the mattress opening closed and sliding away from and opening the receptacle top in a second position when the mattress opening is enlarged.
