Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
172 words
A quick release retainer for a work piece, which comprises: a receptor for the work piece; means for attaching the receptor to a user; means for attaching the work piece to the receptor by contact; means for guarding against accidental separation of said work piece from said receptor, comprising a guard which partially encloses said work piece when positioned on said receptor completely protecting a base portion of said work piece and partially protecting the adjoining sides thereof; said guard including side guards extending parabolically and partially on the adjoining sides of said work piece sloping gradually to the base thereof to the point of connection of said guard on said receptor; and said guard containing a raised portion in the base thereof to enhance the ability of the user to grasp the device; and thereby to facilitate the removal of said work piece from said receptor when the work piece is to be placed in use and simultaneously guard against inadvertent and accidental removal of said work piece from said receptor.
Claim 2
Dependent Claim
172 words
A quick release retainer for a work piece, which comprises: a receptor for the work piece; means for attaching the receptor to a user; means for attaching the work piece to the receptor by contact; means for guarding against accidental separation of said work piece from said receptor, comprising a guard which partially encloses said work piece when positioned on said receptor completely protecting a base portion of said work piece and partially protecting the adjoining sides thereof; said guard including side guards extending parabolically and partially on the adjoining sides of said work piece sloping gradually to the base thereof to the point of connection of said guard on said receptor; and said guard containing a raised portion in the base thereof to enhance the ability of the user to grasp the device; and thereby to facilitate the removal of said work piece from said receptor when the work piece is to be placed in use and simultaneously guard against inadvertent and accidental removal of said work piece from said receptor.
Claim 3
Dependent Claim
40 words
A quick release retainer as defined in claim 1 wherein said guard includes a lip which further protects against the accidental removal of said work piece from said separator, said lip being positioned along the base portion of said guard.
Claim 4
Dependent Claim
73 words
A quick release retainer as defined in claim 1 wherein said base portion includes an elevated central region and depressed side regions so that when said work piece is inserted in said retainer, the bottom of said work piece rests on said central region and the bottom edges of said work piece are elevated above said depressed side region; thereby to facilitate the quick release removal of said work piece from said retainer.
Claim 5
Dependent Claim
51 words
A quick release retainer as defined in claim 3 wherein the central region of said base is apertured to further facilitate the quick release removal of said work piece from said retainer, with the associated structure serving to prevent or inhibit the accidental release of said work piece from said retainer.
