Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
196 words
Stapler assembly, comprising a. a main housing having a grip handle and an operating handle, b. an elongated staple storage compartment underlying the main body and extending in the same general direction as the grip handle, the compartment having a box-like cross-section with an upper wall and side walls, c. a U-shaped staple track slidable along the compartment for loading staples and having a bottom wall which underlies the compartment and upwardly-directed side walls that embrace the side walls of the compartment, the side walls of the track having upper edges that lie substantially below the said upper wall of the compartment, so that a recess is formed by the said upper edge of the track and the side walls of the compartment, and d. an attachment formed of an elastomer material and having a first portion lying against the bottom wall of the track with a pair of arms embracing the side walls of the track, the arms having inwardly-directed lugs that reside in the said processes, the attachment having a second portion that lies at an acute angle to the first portion and, carries a staple-bending device in a position underlying the main housing.
Claim 2
Dependent Claim
196 words
Stapler assembly, comprising a. a main housing having a grip handle and an operating handle, b. an elongated staple storage compartment underlying the main body and extending in the same general direction as the grip handle, the compartment having a box-like cross-section with an upper wall and side walls, c. a U-shaped staple track slidable along the compartment for loading staples and having a bottom wall which underlies the compartment and upwardly-directed side walls that embrace the side walls of the compartment, the side walls of the track having upper edges that lie substantially below the said upper wall of the compartment, so that a recess is formed by the said upper edge of the track and the side walls of the compartment, and d. an attachment formed of an elastomer material and having a first portion lying against the bottom wall of the track with a pair of arms embracing the side walls of the track, the arms having inwardly-directed lugs that reside in the said processes, the attachment having a second portion that lies at an acute angle to the first portion and, carries a staple-bending device in a position underlying the main housing.
Claim 3
Dependent Claim
