ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a paper hole punch. More particularly, the invention relates to a paper hole punch which applies a reinforcing member to a sheet of paper as a hole is created in the sheet of paper.
2. Description of the Prior Art
Hole punches for creating a series of holes in a sheet of paper are well known. In most instances, the holes are created so that the sheet of paper may be securely placed within a binder. Unfortunately, however, holes made in this manner are often fragile, and may easily be torn from the binder.
Reinforcing members have, therefore, been developed for positioning about holes created within a sheet of paper. These reinforcing members are commonly applied to the sheet of paper after the holes have been formed by a hole punch. Hole punches have been developed for applying reinforcing members adjacent formed holes as the holes are created by the hole punch. These prior hole punches are generally difficult to use and do not efficiently apply reinforcing members to a sheet of paper as holes are created therein.
As a result, a need exists for a hole punch which efficiently and effectively applies reinforcing members about a hole generated when the hole punch cuts through a sheet of paper. The present invention provides such a hole punch.
SUMMARY OF THE INVENTION
It is, therefore, an object of the present invention to provide a reinforcing hole punch including a reciprocating punch member supported for movement toward a base. The reciprocating punch member is actuated to form a hole within a sheet of paper positioned on the base. The hole punch also includes a dispensing sleeve positioned about the punch member, defining a space between an inner wall of the dispensing sleeve and the punch member, in which reinforcing members are positioned for attachment to a sheet of paper when the punch member is actuated to form a hole within a sheet of paper.
It is also an object of the present invention to provide a hole punch wherein the dispensing sleeve includes an open end adjacent a distal end of the punch member, and the open end includes a stopper for controlling the dispensing of reinforcing members.
It is another object of the present invention to provide a hole punch wherein the stopper includes an opening slightly smaller than the reinforcing members to control the dispensing of the reinforcing members until the punch member is actuated to form a hole within a sheet of paper.
It is a further object of the present invention to provide a hole punch wherein a spring is positioned within the dispensing sleeve to force a reinforcing member into contact with a sheet of paper when the punch member is actuated to form a hole in the sheet of paper.
It is also an object of the present invention to provide a hole punch wherein the dispensing sleeve is releasably positioned about the punch member.
It is another object of the present invention to provide a hole punch including a second reciprocating punch member supported for movement toward the base, wherein the second reciprocating punch member is actuated to form a hole within a sheet of paper positioned on the base. The hole punch also includes a second dispensing sleeve positioned about the second punch member to define a space between an inner wall of the second dispensing sleeve and the second punch member in which reinforcing members are positioned for attachment to a sheet of paper when the second punch member is actuated to form a hole within a sheet of paper.
Other objects and advantages of the present invention will become apparent from the following detailed description when viewed in conjunction with the accompanying drawings, which set forth certain embodiments of the invention.
