DISPOSABLE SAFETY ROTARY RAZOR
Abstract
A cylindrical hollow sleeve has an axial slot and a handle
extending at right angles. An elongated member is detachably
disposed in the sleeve and is manually rotatable about its axis.
The member carries a plurality of cutting means which are
successively indexed at the slot for shaving.

Claims
I claim:
1. A disposable safety rotary rotary razor comprising:
A. an elongated semi-rigid outer cylindrical sleeve open at both
ends and having an open slot extending axially throughout the
length of said sleeve,
B. a handle fixed to the midpoint of said sleeve and extending at
right angle thereto,
C. an elongated hexagonal spool disposed within said sleeve and
manually rotatable therein on an axis parallel to the wall of said
sleeve, said spool having in cross section the shape of a hexagon
with each of its six flat faces extending the entire length of said
spool,
D. six separate stainless steel shaving blades, each of said blades
being fixed to one of the flat faces of said elongated spool
extending throughout the length thereof and each of said shaving
blades having a cutting edge protruding outwardly from said spool
extending beyond the flat faces to which each blade is fixed,
E. each of said six blades being rotatable with said spool and
means to index each of said blades opposite the open slot of said
elongated semi-rigid outer cylindrical sleeve and the cutting edge
of each blade adapted to protrude outwardly through said slot,
F. an axially extending bore formed in said elongated hexagonal
spool and a control knob for each end of said spool, each control
knob having a pin adapted to enter said bore in a manner to fix
said control knobs to opposite ends of said spool and manually
rotate said spool,
G. a semi-flexible cylindrical shaped shim adapted to be fitted
within said semi-riged outer cylindrical sleeve and to surround
said elongated hexagonal spool which is disposed within said sleeve
whereby both said shim and said spool are disposed within said
semi-rigid outer cylinder, said shim being adhesed to the inner
wall of said outer cylinder and said spool being rotatable within
both said shim and said outer cylinder,
H. an open slot formed in said cylindrically shaped semi-flexible
shim said slot extending parallel to the open slot of the
semi-rigid outer cylindrical sleeve in which it is disposed and to
which it is adhesed said slot having inwardly turned edges along
the length of the slot to form blade wiper reeds and arranged to
press inwardly against and contact the blades as they are rotated
and moved out of shaving position.
Description
SUMMARY OF THE INVENTION
This invention relates to a new and completely new concept in a
safety razor. This new, one unit, inexpensive, disposable rotary
razor provides a super floating action shave. It has fewer parts
than any shaver on the market today. In addition, it also has less
parts in the complete unit than can be found in just a blade
dispenser itself. This razor is easy to use and, because of its
principles, gives a really clean, close and comfortable shave.
Because of its unique design, this invention lends itself well to
practical manufacturing.
This safety rotary razor is made inexpensively, is of one unit, and
can be thrown away after a plurality of shaves by the user. It can
be made of bright colored plastic. It employs a plurality of
blades, for example, six blades. The blades are adhesed to an
hexagon-shaped plastic inner spool.
This one-unit spool holder and handle are made of an inexpensive
brightly colored plastic and can have a shim of semi-flexible
teflon plastic material which is cylindrically shaped and adapted
to be fitted within said outer spool holder and adhesed to the
inner surface of said outer holder in a manner to serve as a blade
shield and blade wiper reed. This dual function is accomplished
through the provision of an elongated slot extending lengthwise of
said cylindrically shaped semi-flexible shim, the edges of said
slot being turned inwardly along the length of said slot to form
blade wiper reeds which are arranged to press inwardly and contact
the blades to wipe said blades as they move out of shaving
position.
Two spool plug ends with a red marker on them can fall in line with
the last blade which also has a thin red line on it to remind the
user that he is on his last blade. This will give him ample time to
buy and replace the razor in use.
To change the blade, all one has to do is to hold the spool, plug
end between his thumb and first finger (left hand) (cutting edge
up), and move the handle down until a clicking sound caused by the
passing of the new blade as it is rotated past the inwardly
pressing blade wiper reed which is in close contact with said new
blade as it is rotated into operative position and a new blade
comes into view. It is again ready for use.
BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings:
FIG. 1 is an exploded view of my invention; and
FIG. 2 is a side view of my invention in use.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to FIG. 1, a hollow elongated plastic semi-rigid
sleeve 10, open at both ends, has an axially extending slot 12. A
plastic handle 30 is secured to the center of the sleeve and
extends at right angles thereto. An elongated hexagon shaped
plastic spool 14 has an axial bore 16. A separate stainless steel
blade 18 is secured to each of the axially extending faces with a
cutting edge which extends thereout. A thin flexible teflon sleeve
20 with an axial slot 22 having inwardly turned blade wiper reed
edges is disposed axially within the sleeve 10 with slot 22 aligned
with slot 12. Spool 14 is disposed within the sleeve 20 so that the
cutting edge of a blade extends outwardly and downwardly from the
aligned slots 12 and 22 for use in shaving. Control knobs 24 have
axially extending pins 26 which engage opposite ends of the spool.
These knobs have aligned markers 28 which will point to the last
blade in use after all other blades have been successively indexed
at the slots for use whereby the user knows he should throw the
entire unit out and obtain a replacement.
While I have described my invention with particular reference to
the drawings, such is not to be considered as limiting its actual
scope.
