Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
162 words
Apparatus for inserting a module into and removing it from an opening by applying forces to one end thereof with respect to the opening and comprising, in combination: force means for attachment at one end to a module to be inserted and extracted and for attachment at the other end to a pivotal connection, an imaginary line between the points of attachment forming a reference vector; mounting means for attachment to a structure defining an opening into which the module is to be inserted and extracted from; and pivotal means connecting said force means to mounting means whereby insertion forces on a module move said pivotal means to a first position wherein the reference vector has a substantial component perpendicular to the base of the opening and extraction forces on a module move said pivotal means to a second position, displaced in space with respect to said first position, wherein the reference vector is substantially parallel with the base of the opening.
Claim 2
Dependent Claim
162 words
Apparatus for inserting a module into and removing it from an opening by applying forces to one end thereof with respect to the opening and comprising, in combination: force means for attachment at one end to a module to be inserted and extracted and for attachment at the other end to a pivotal connection, an imaginary line between the points of attachment forming a reference vector; mounting means for attachment to a structure defining an opening into which the module is to be inserted and extracted from; and pivotal means connecting said force means to mounting means whereby insertion forces on a module move said pivotal means to a first position wherein the reference vector has a substantial component perpendicular to the base of the opening and extraction forces on a module move said pivotal means to a second position, displaced in space with respect to said first position, wherein the reference vector is substantially parallel with the base of the opening.
Claim 3
Dependent Claim
131 words
Apparatus for inserting a module into an opening in a structure in a direction parallel to the base of the structure opening and holding the module with a force component perpendicular to the base and for extracting the module from the opening in the structure comprising, in combination: force means for providing insertion and extraction forces; mounting means; pivotal means connecting said force means and said mounting means, said pivotal means moving suddenly between first and second positions upon changes between insertion and extraction forces whereby the vector angle of insertion force has a substantial component perpendicular to the base and the vector angle of extraction force has a substantially zero component perpendicular to the base and said first and second positions are displaced in space one relative to the other.
Claim 4
Dependent Claim
131 words
Apparatus for inserting a module into an opening in a structure in a direction parallel to the base of the structure opening and holding the module with a force component perpendicular to the base and for extracting the module from the opening in the structure comprising, in combination: force means for providing insertion and extraction forces; mounting means; pivotal means connecting said force means and said mounting means, said pivotal means moving suddenly between first and second positions upon changes between insertion and extraction forces whereby the vector angle of insertion force has a substantial component perpendicular to the base and the vector angle of extraction force has a substantially zero component perpendicular to the base and said first and second positions are displaced in space one relative to the other.
Claim 5
Dependent Claim
155 words
Apparatus for inserting a module into and removing it from an opening by applying forces to one end thereof with respect to the opening and wherein it is desirable that the module be inserted and removed in the direction substantially parallel with a base of the opening comprising, in combination: means for applying insertion forces to the one end of said module whereby a substantial component of the insertion forces is in a direction perpendicular to the direction of movement of said module of the said opening for reducing movement in either the direction of said substantial component of force or the direction of movement of the module into the opening as the insertion operation is completed; and means for extracting said module at said one end of said module by applying a force having substantially no components in the directions perpendicular to the direction of movement of said module upon insertion into the opening.
Claim 6
Dependent Claim
155 words
Apparatus for inserting a module into and removing it from an opening by applying forces to one end thereof with respect to the opening and wherein it is desirable that the module be inserted and removed in the direction substantially parallel with a base of the opening comprising, in combination: means for applying insertion forces to the one end of said module whereby a substantial component of the insertion forces is in a direction perpendicular to the direction of movement of said module of the said opening for reducing movement in either the direction of said substantial component of force or the direction of movement of the module into the opening as the insertion operation is completed; and means for extracting said module at said one end of said module by applying a force having substantially no components in the directions perpendicular to the direction of movement of said module upon insertion into the opening.
Claim 7
Dependent Claim
103 words
Apparatus for inserting and extracting a container with respect to an opening having electrical connections at the rear thereof wherein the opening has a horizontal base and wherein the container has electrical connections at the rear thereof and force coacting means at the front thereof and further wherein vertical force applied to said container upon extraction tends to bend or produce breakage of the electrical connections comprising, in combination; means for applying insertion forces to said container having a substantial force component in the vertical direction; and means for applying extraction forces wherein the vertical components of the extraction forces are substantially zero.
Claim 8
Dependent Claim
103 words
Apparatus for inserting and extracting a container with respect to an opening having electrical connections at the rear thereof wherein the opening has a horizontal base and wherein the container has electrical connections at the rear thereof and force coacting means at the front thereof and further wherein vertical force applied to said container upon extraction tends to bend or produce breakage of the electrical connections comprising, in combination; means for applying insertion forces to said container having a substantial force component in the vertical direction; and means for applying extraction forces wherein the vertical components of the extraction forces are substantially zero.
Claim 9
Dependent Claim
124 words
Apparatus for supplying insertion and extraction forces to a module with respect to a base comprising, in combination: mounting means for attachment to a base; force means for applying insertion and extraction forces, said force means having first and second ends and including means for coacting with a module at said first end thereof and including pivotal means at the second end thereof; and means connecting said pivotal means of said force means to said mounting means for permitting movement of said pivotal means between first and second space displaced positions and thus the second end of said force means upon a change between the application of insertion and extraction forces thereby changing the angles of force vectors applied with respect to a reference.
Claim 10
