APPARATUS FOR THE CARE OF THE BODY
Abstract
An apparatus which serves for the care of the body and which
consists of a protective plate provided with an elongated handle, a
cover plate and a cutting blade. The protective plate includes two
planing holes and two slits, one extending transversely to the
longitudinal axis and the other extending on the longitudinal axis
of the apparatus. Each slit possesses at least one exposed tongue.
The cover plate is provided with a bent-up tab which has at least
one slit to enable it to be locked to the protective plate. The tab
serves for the reception of an elongated guide slot in the
removable and replaceable blade and passes through one of the slits
of the protective plate whereby the exposed tongue engages the slit
of the tab to clamp the blade.

Description
BACKGROUND OF THE INVENTION
This invention relates to an apparatus for the care of the
body.
Appliances of this kind are mainly used for callous cutters and are
known in a variety of versions. All of them, however, suffer from
the major drawback that they only enable a draw cut, rather than a
peeling action, to be applied to the callosity of the skin. It has
been found in practice, however, that it is more frequently
convenient, particularly for a user wishing to remove callouses
from his own skin, but for the chiropodist likewise, to peel the
callous off, rather than to remove it by a draw cut action. It is
true that appliances are already known that enable the callous to
be peeled. But these, in turn, do not enable a draw cut action to
be effected if desired.
SUMMARY OF THE INVENTION
It is, therefore, the object of the present invention to improve on
the prior art, in such a way that the callouses can be removed not
only in the conventional manner, by a draw cut, but also by a
peeling action, if desired.
To attain this object the present invention provides an apparatus
for the care of the body which comprises an elongated handle; a
protective plate carried by one end of the elongated handle and
provided with a first slit and a second slit. The first slit
extends transversely to the longitudinal axis of the apparatus and
possesses at least one exposed tongue. The second slit is situated
on the longitudinal axis of the apparatus, intersecting the first
slit and also possesses at least one exposed tongue which extends
at right angles to the tongue of the first slit. The protective
plate is further provided with two planing holes extending at right
angles with respect to each other; and a cover plate provided, to
enable it to be locked to the protective plate, with a bent-up tab
which has at least one slit which serves for the reception of the
elongated slot of a replaceable blade. The tab of the cover plate
is adapted alternatively to be passed through one of the slits in
the protective plate whereby the exposed tongue firmly engages the
slit in the tab to clamp the blade.
If callouses are to be peeled off with this apparatus, after it has
first been used for the application of a draw cut to the callosity,
all that is necessary is to reposition the cover plate and the
blade by an angle of 90.degree. with respect to the protective
plate. The bent-up tab of the cover plate will then pass through
the slit situated in the longitudinal axis of the protective plate
of the apparatus and become locked to this latter plate as a result
of the fact that its exposed tongue engages the slit of the tab of
the cover plate.
The invention also resides in the fact that the protective plate
and the cover plate of the apparatus are of the shape of a
spherical segment.
This construction for the protective plate and the cover plate of
the apparatus ensures that the blade, no matter whether its cutting
edge is situated in the zone of one planing hole or of the other
planing hole of the protective plate, can be clamped in a curved
position, in the manner already known.
According to a further proposal covered by the invention, each slit
of the protective plate of the apparatus is provided with two
exposed tongues which correspond to slits belonging to the tab of
the cover plate and which are situated close to the ends of each
slit of the protective plate.
This ensures that after two tongues of the protective plate have
engaged the slits of the tab of the cover plate, the entire length
of this latter will rest against the protective plate, with an even
tractive force.
BRIEF DESCRIPTION OF THE DRAWING
An embodiment of the invention will now be described by way of
example and with reference to the accompanying drawing, in
which:
FIG. 1 is a front elevational view of an apparatus according to the
invention;
FIG. 2 is a side view thereof;
FIG. 3 is a plan view of the cover plate of the apparatus, and
FIG. 4 is a side view thereof.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The apparatus shown in the drawing consists of a protective plate 1
with an elongated handle 2 and a cover plate 3, a two-edged blade 4
of the flat type being clamped between said cover plate 3 and said
protective plate 1. The protective plate 1 is provided with a
planing hole 5, one cutting edge of the blade 4 being situated in
the zone of said hole, and also with a slit 6 positioned
transversely to the longitudinal axis of the apparatus. The slit 6
is provided, on one of its longitudinal edges, in the vicinity of
each of its ends, with a tongue 7 cut out of the material so as to
occupy an exposed self-supporting position. The cover plate 3 is
provided with a bent-up tab 8 which properly positions the blade 4
by engaging a guide slot located in the blade 4. The tab 8 is
provided with two slits 9 which correspond to the tongues 7 of the
protective plate 1 and which can be engaged by said tongues 7 in
order to lock the protective plate 1 to the cover plate 3.
The protective plate 1 is provided with a second slit 10 which is
situated on the longitudinal axis of the apparatus and intersects
the slit 6, two exposed tongues 11, formed by being cut out of the
material and situated at right angles to the tongue 7, being
likewise provided on one longitudinal edge of the said second slit
10 and in the vicinity of its respective ends. After the cover
plate 3 with the blade 4 has been repositioned by an angle of
90.degree. and after the tab 8 of the said cover plate 3 has passed
through the slit 10 of the protective plate 1, the tongues 11 of
the latter engage the slits 9 of the tab 8 of the cover plate 3, in
order to enable the cover plate 3 to be locked to the protective
plate 1. One of the cutting edges of the blade 4 is thereafter
situated in the zone of a second planing hole 12 which is provided
in the protective plate 1 and which is situated at right angles to
the planing hole 5. The apparatus can now be used for the removal
of the callous by a peeling action. According to a further
characteristic of the invention, the protective plate 1 and the
cover plate 3 have the shape of a spherical segment, enabling the
blade 4 to be clamped in a curved position, no matter what position
it occupies in relation to the protective plate 1 and the cover
plate 3.
It is naturally within the scope of the invention for a third
planing hole to be provided, situated opposite the planing hole 12,
thus enabling a peeling action to be carried out with the apparatus
by a left-handed person likewise.
