PIVOT ASSEMBLY FOR STAPLER WITH SWINGABLE ARM

ASSEMBLAGE A PIVOT POUR AGRAFEUSE A BRAS OSCILLANT

English Abstract

In a pivoting arm stapling device, it is known to have a
pivot system applicable only to large staplers of a type no
longer in use. In this invention, the pivot system enables
the pivoting arm to be applied to any design of stapler
currently in use.

Claims

I claim:
1.In a stapling device of the character described, a pivot
plate with an integral pivot pin, a staple driver arm
pivotally mounted to said plate by means of said pin, a
spring-steel washer between the underside of said arm and
the bottom of said pin allowing for movement of said arm.

Description

~,A 2 1 1 64 74


This invention relates to stapling devices, particularly
the low profile desktop type that pivot, enabling the user
to staple material either on a line parallel to the edge of
the stapler or on a line perpendicular thereto.
Pivoting arm staplers heretofore have been cumbersome
using a large plunger to drive the staple through the
material.
The object of the present invention is to enable a
pivoting arm to be utilized in a more compact, low pro~ile
stapler.
Other objects and advantages of the invention will become
apparent upon reading of the following description, when
taken in conjunction with the drawings in which:
Fig.1 is a perspective view of a pivotal stapling device
in the perpendicular stapling position with a cutaway
showing the location of the pivot and pivot plate.
~ ig.2 is a perspective view of a pivotal stapling device
in the parallel stapling position.
Fig.3 is a sectional view taken along line A in Fig.1.
Fig.4 is a view of the pivot plate and the portion of the
staple carriage with which it comes in contact.
Referring to the drawings, ~ig.1 shows a stapler comprised
of a base 1 having an anvil 2 with staple bending recesses
3, mounted at the forward end of base 1 and two tabs 4
integral to the back end of base 1. An arm 5 is pivotally
mounted to the tabs 4 by means of rivets 6. Integral to the
forward end of arm 5 is pivot plate 7.
- Staple carriage 8 is pivotally mounted to the staple
driver arm 9 by rivets 10.
Pivot pin 11 is integral to pivot plate 7. Staple driver
arm 9 is mounted to pivot plate 7 by means of pivot pin 11
passing through hole 16 at the forward end of arm 9 and held
` in place by washer 12 and spring-steel washer 13 enabling
arm 9 to be rotated to any number of positions.
Staple driver arm 9 has a number of holes 15 to seat nubs
14 to keep members in position for stapling when staple
driver arm 9 is parallel or perpendicular to base 1.
The staple driving mechanism and the means by which the
staples are urged towards the driving mechanism are known in
the art as are the means for staple loading.
The invention exemplifies features unknown in the art as
they relate to the low profile stapler described above. I do
not, howeverJ wish to be limited to the specific structure
shown. Modifications may be made in the future that are
within the spirit of my invention and the scope of my
claims.
