Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
158 words
A process for molding a foam arm for a chair having a tubular passageway for the passage of control mechanisms through the arm, comprising the steps of: providing a mold having a cavity and with a nipple located on an inner surface of the mold cavity; attaching one end of a tube to said nipple; securing another end of the tube to an insert and positioning said insert into a recess located at an outer edge of said cavity; filling said cavity with a solidifiable material; closing said mold; allowing the material to solidify to create an arm rest with an inserted tube; and then opening said mold and removing the arm rest by first lifting said arm rest upwardly at said outer edge to a point where said insert is raised above a lip of said recess, then sliding said one end of said tube off said nipple and finally lifting said arm rest form the mold.
Claim 2
Dependent Claim
158 words
A process for molding a foam arm for a chair having a tubular passageway for the passage of control mechanisms through the arm, comprising the steps of: providing a mold having a cavity and with a nipple located on an inner surface of the mold cavity; attaching one end of a tube to said nipple; securing another end of the tube to an insert and positioning said insert into a recess located at an outer edge of said cavity; filling said cavity with a solidifiable material; closing said mold; allowing the material to solidify to create an arm rest with an inserted tube; and then opening said mold and removing the arm rest by first lifting said arm rest upwardly at said outer edge to a point where said insert is raised above a lip of said recess, then sliding said one end of said tube off said nipple and finally lifting said arm rest form the mold.
Claim 3
Dependent Claim
33 words
The process of claim 1, wherein the securing of the other end of the tube is by attachment of the tube to a removable insert located at the edge of the cavity surface.
Claim 4
Dependent Claim
23 words
The process of claim 2, wherein the removable insert remains attached to the arm rest as it is removed from the mold cavity.
Claim 5
Dependent Claim
20 words
The process of claim 3, wherein the removable insert is removed from the arm rest after removal from the mold.
Claim 6
Dependent Claim
27 words
The process of claim 2, wherein the solidifiable material is placed around the removable insert and its securing connection to form a recess in the arm rest.
Claim 7
Dependent Claim
21 words
The process of claim 1, including the step of placing a reinforcement member into the mold prior to the filling step.
Claim 8
Dependent Claim
27 words
The process of claim 6 including the step of peggingly securing the reinforcement member to the mold after the placing step and prior to the filling step.
Claim 9
Dependent Claim
57 words
The process of claim 7, wherein the arm rest is removed from the mold cavity by lifting the arm rest out of the mold through the step of pushing on the pegged connection of the reinforcement member to the mold form and wherein this lifting step takes place prior to sliding the tube off the nipple insert.
Claim 10
Dependent Claim
22 words
The process of claim 1, wherein a removable insert is positioned in the mold cavity by securing it to a reinforcement member.
Claim 11
Dependent Claim
22 words
The process of claim 2, wherein the removable insert is positioned in the mold cavity by securing it to a reinforcement member.
Claim 12
Dependent Claim
126 words
The process of claim 1, wherein the step of moving the arm rest from the mold is made easier by having the mold cavity formed by two mold forms, each form having a depression therein, and wherein the depressions face each other to define the mold cavity, and wherein the depressions are graduated in depth along one dimension of the respective mold form from a shallow end to a deep end, and wherein the deep end of one mold form is adjacent the shallow end of the other mold form and wherein the removal process includes opening of the mold and lifting an end of the arm rest at the shallow end so it clears the mold prior to sliding off the tube from the nipple.
Claim 13
Dependent Claim
126 words
The process of claim 2, wherein the step of moving the arm rest from the mold is much easier by having the mold cavity formed by two mold forms, each form having a depression therein, and wherein the depressions face each other to define the mold cavity, and wherein the depressions are graduated in depth along one dimension of the respective mold form from a shallow end to a deep end, and wherein the deep end of one mold form is adjacent the shallow end of the other mold form and wherein the removal process includes opening of the mold and lifting an end of the arm rest at the shallow end so it clears the mold prior to sliding off the tube from the nipple.
Claim 14
Dependent Claim
124 words
A process for molding a foam arm for a chair having a tubular passageway for the passage of control mechanisms through the arm, comprising the steps of: providing a mold having a cavity and with a nipple located on an inner surface of the mold cavity; placing a reinforcement member into the mold; attaching one end of a tube to said nipple; securing another end of the tube to an insert and securing the insert to the reinforcement member; sliding the insert on the reinforcement member to a desired position; filling said cavity with a solidifiable material closing said mold; allowing the material to solidify to create an arm rest with an inserted tube; and then opening said mold and removing the arm rest.
