Abstract
A punch for punching a sheet of material, the punch having a body formed with a fissure for receiving the sheet of material, a pivot shaft defining a pivot point, and a lever pivotably mounted about said pivot shaft has an open position and a closed position. A block is provided which is positionable between the lever and the body. The body is provided with longitudinal support ridges and the lever is provided with side ridges, with the pivot point positioned in substantially the same plane as the longitudinal support ridge so that when the punch is closed, the side ridges of the lever pass outside of the support ridges of the body in a nesting relationship, allowing the punch to form a flat profile when closed.
Claims13
A punch capable of punching a sheet of material, the punch comprising:
- a punch body having a bottom portion with a surface upon which the punch body rests during use of the punch, an upper portion over the bottom portion, and a fissure, laterally disposed between the bottom portion and the upper portion and capable of receiving the sheet of material;
- a lever pivotably coupled adjacent to a rear of the punch body, the lever having an open position in which a nose of the lever is spaced apart from a front of the upper portion of the punch body and a closed position in which the nose is adjacent to the front of the upper portion of the punch body and the lever is oriented parallel to an orientation of the punch body, the nose including an underside with a receptacle;
- a punch block;
- having an upper surface, the punch block positionable between the lever and the punch body and movable along a first axis generally perpendicular to the fissure;
- and
- a locking mechanism accessible and operable from the surface upon which the punch body rests during use of the punch, the locking mechanism comprising a slide at least partially recessed in a front of the bottom portion of the punch and a hook latch associated with the slide, the slide being movable between an unlocked position and a locking position, the hook latch capable of engaging the receptacle of the lever when the lever is depressed to the closed position.
A punch capable of punching a sheet of material, the punch comprising:
- a punch body having a bottom portion with a surface upon which the punch body rests during use of the punch, an upper portion over the bottom portion, and a fissure, laterally disposed between the lower bottom portion and the upper portion and capable of receiving the sheet of material;
- a lever pivotably coupled to the punch body adjacent to a rear of the punch body, the lever having an open position in which a nose of the lever is spaced apart from a front of the upper portion of the punch body and a closed position in which the nose of the lever is adjacent to the front of the upper portion of the punch body and the lever is oriented over the punch body substantially parallel to the punch body, the nose of the lever including an underside with a receptacle;
- a punch block having an upper surface, the punch block positionable between the lever and the punch body and movable along a first axis generally perpendicular to the fissure;
- and
- a locking mechanism accessible and operable from a bottom surface of the punch body, the locking mechanism comprising a slide and a hook latch, the slide at least partially recessed in a front of the bottom surface of the punch body and movable between an unlocked position and a locking position, movement of the slide to the locking position enabling the hook latch to secure the lever in the closed position by engaging the receptacle of the lever and preventing the lever from moving to the open position.
The punch of 12, wherein the punch body is capable of retaining another portion of the resilient member.
