ARTICLE HOLDER
Abstract
A holder for knives or the like implements, serving to maintain
them with their cutting edges in a protected enclosed position, and
permitting ready selective insertion and removal of the knife, or
the like from the holder. The holder is formed by a block member
having an interior vertically extending channel therein defined by
a vertically extending surface spaced from an inclined surface,
with the lower end of the inclined surface closer to the vertically
extending surface. A locking member is loosely positioned in said
channel for sliding between said surfaces, and a stop member at the
lower end of said channel limits the downward movement of said
locking member to prevent its being wedged into a jammed position
between said surfaces, whereby a knife or the like inserted into
said channel will be engaged by said locking member against said
vertical surface. The locking member is formed with a chamfered
leading edge serving the twofold function of implementing insertion
of the knife blade and permitting honing of the blade.

Description
BACKGROUND OF THE INVENTION
This invention relates to the art of article holders, and more
particularly to an article holder for protectively and decoratively
maintaining bladed articles such as knives or the like with the
blade maintained in a protected enclosed position, and with the
knife or the like available for selective removal or positioning in
the holder.
The storage of bladed articles such as knives or the like requires
that the knife be supported in a position so that the blade is kept
from contacting other surfaces which may have a dulling effect
thereupon, and further that the knife be so positioned that though
the handle is readily accessible for gripping by a user, the blade
is maintained in a position minimizing the likelihood of
inadvertent contact therewith by the hands of the user. To this
end, a variety of knife holders or knife racks have been evolved in
which a knife may be positioned with its handle exposed, but with
the blade maintained in a relatively protected position remote from
the hands of the user.
Among the more satisfactory holders are those employing a rolling
member movable on an inclined plane towards a vertical surface to
sandwich the article to be held between the rolling member and the
vertical surface. Thus Hanschar in U.S Pat. No. 3,071,252 discloses
a holder for bladed implements in which a ball is arranged in an
inclined cylindrical bore, with the bore having a lower opening
intersecting a vertical slot, so that the ball moving under the
action of gravity to the lower extremity of the bore will wedge
against a vertical wall of the slot to sandwich an article in the
slot.
Similarly, Grottola in U.S. Pat. No. 3,294,350 discloses a cylinder
arranged to slide on an inclined plane towards a vertical surface
so that an article positioned adjacent the vertical surface will be
sandwiched thereagainst by the action of the roller.
Problems arise in utilizing holder devices of the above-described
type in that the locking member, be it a ball or a cylinder tends
to wedge under the action of gravity at the lower ends between the
inclined surface and the vertical surface, with the locking member
often being frozen into a position at its lower end preventing
insertion of an article into the holder.
Additionally, where it is desired to support a bladelike element,
such as a knife or the like, the use of a cylindrical ball as a
locking member produces a line contact in a direction axially of
the blade axis, so that a downward pull on the knife with respect
to the holder produces a scoring of the blade. Where a cylindrical
locking member is employed, as disclosed by Grottola, problems are
encountered in positioning the knife between the cylinder surface
and the vertical surface which may become tightly wedged.
Further problems arise in utilizing holders of the aforedescribed
type in connection with knives in that the sharp edge of the knife
blade tends to become dulled as a result of its contact with the
holder surfaces.
BRIEF DESCRIPTION OF THE INVENTION
It is with the above considerations in mind, that the present
improved article holder has been evolved permitting the utilization
of a locking member moving over an inclined surface against a
vertical surface to wedge an article between the locking member and
the vertical surface, without the heretofore encountered problems
of having the locking member "freeze" in a locked position, and
implementing use of the article holder for bladed articles such as
knives or the like.
It is accordingly among the primary objects of this invention to
provide an improved article holder employing a locking member
sliding over an inclined surface against a vertical surface to
sandwich an article to be retained between a locking member and the
article surface.
Another object of the invention is to provide an article holder of
the above-described type in which freezing of the locking member is
prevented.
A further object of the invention is to provide an article holder
of the above-described type in which insertion of a bladed article
such as a knife or the like between the vertical surface and the
locking member is facilitated.
Another object of the invention is to provide an article holder of
the above-described type particularly adapted for use in holding
knives in which the cutting edge of the blade is protected from
dulling.
These and other objects of the invention which will become
hereafter apparent are achieved by forming the holder with channels
therein. The channel is defined by a vertically extending surface,
and an inclined surface spaced from said vertically extending
surface, with the inclined surface angled upwardly and outwardly
with respect to the vertical surface so that the lower end of the
inclined surface is closer to the vertical surface and the upper
end of the inclined surface. A vertically extending slot is formed
in the block member extending adjacent the vertical surface, and a
locking member is movably mounted in said channel. According to the
invention, the locking member is preferably in the shape of a right
circular cylinder arranged with its axis perpendicular to the axis
of the channel so that the cylinder may roll on the inclined
surface of the channel. A stop member is formed at the lower end of
the channel to limit the downward movement of the locking member so
as to insure clearance between the vertical surface and the locking
member, thereby preventing "freezing" of the locking member in the
channel. This stop member may take the form of a pin extending into
the channel, or the channel may be formed with a bottom wall
limiting movement of the locking member.
A feature of the invention resides in the fact that the locking
member formed in the shape of a right circular cylinder is provided
with a chamfered edge at the end thereof adjacent to the slot of
the channel so as to implement sandwiching of a knife or the like
between the locking member and the vertical surface.
Another feature of the invention resides in the fact that the
chamfered edge of the cylinder may serve to permit honing of the
knife by reciprocation of the knife blade with respect to the
chamfered edge of the cylinder.
A further feature of the invention resides in the formation of the
block or locking member of a magnetic material, or the insertion of
a magnetic insert into the block or a locking member so as to
insure retention of a ferromagnetic knife blade in the holder,
aiding the holding action of the locking member.
A further feature of the invention resides in the provision of a
cushioning member at the rear surface of the channel opposite to
the entry slot to cushion the cutting edge of the knife inserted
therein.

DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
Referring now more particularly to the drawings, like numerals in
the various figures will be employed to designate like parts.
As illustratively shown in FIG. 1, the holder 10 made in accordance
with the teachings of the invention is formed of a block member 11
having an interior vertically extending channel 14, and a
vertically extending slot 16 extending through the front surface of
block 11 from the interior of the channel 14 to the exterior of the
block 11, and from the top to the bottom thereof.
The channel 14 which is open at top and bottom is defined by a
front wall 18, a rear wall 19 and spaced sidewalls 20. One side of
the sidewall 20 (to the right as viewed in FIG. 1) is formed with a
downwardly inclined surface 22, as best seen in the broken away
portion in FIG. 1, and the other side of sidewall 20 (to the left
as viewed in FIG. 1) is formed with a vertically extending surface
24.
According to the illustrated embodiment of the invention, the block
11 is formed with a plurality of channels 14 so as to facilitate
accommodation of a plurality of knife members or the like. It will
be understood by those skilled in the art that the number of
channels in the block 11 may be varied dependent on the uses to
which the holder 10 is to be put. In Order to facilitate mounting
of the holder 10 onto a wall surface, flanges 24 and 25 are
extended at each side of the block 11.
A locking member 30 is formed in accordance with the teachings of
the invention in the shape of a right circular cylinder, as best
seen in FIGS. 1 and 2 with a chamfered edge 32, for a purpose to be
hereinafter described.
In the embodiment of the invention illustrated in FIG. 1, a lower
stop member in the form of pin 35 is positioned at the bottom of
channel 14 at a point such that the locking member 30 is limited in
its downward movement to a position such that there will be
clearance between the surfaces of the sidewalls of the channel 14
and the cylindrical surface of the locking member 30, to prevent
freezing of the locking member in the channel. In the FIG. 1
embodiment of the invention, the upper limit of movement of the
locking member is limited by an upper pin 37.
In the embodiment of the invention illustrated in FIG. 2, an
arrangement has been shown facilitating fabrication of the holder
10 of plastics materials by the utilization of conventional
plastics molding techniques. The block 11, and channels 14 are as
above described in connection with the FIG. 1 embodiment of the
invention, as is the locking member 30. In order to facilitate
molding, and simplify production costs, in lieu of the stop members
35 and 37, the channel is provided with a bottom plate 40 and a top
plate 42 which are substantially identical and formed with slots 44
and 45 respectively aligned with the slot 16 in the front wall of
the block. The spacing between the lower ends of inclined surface
22 and vertical surface 24 in the FIG. 2 embodiment of the
invention is such that when the bottom wall 40 is in position as
illustrated, it acts as a stop member limiting the downward
movement of the locking member 30 to a position such that there
will be clearance between the cylindrical surface of the locking
member 30 and the surfaces 22 and 24 as above described in
connection with stop member pin 35 as seen in FIG. 3.
In order to minimize the likelihood of dulling of a knife edge
against the rear wall 19 of the block, a cushion formed of a
resilient material, such as foamed rubber, polyurethane, or any
relatively resilient material having a nonabrasive surface is
provided in the form of cushions 45 arranged in slots aligned with
slots 16 and formed in the rear wall 19.
Though the entire holder may be made of a ferromagnetic material
which is magnetized to implement the engagement with the
ferromagnetic blade of the knife, it is found that security of
holding of an article may be implemented by embedding a magnetic
insert 50 adjacent the vertical surface 24, as best seen in FIG.
5.
OPERATION
The aforedescribed holder 10 may be satisfactorily fabricated of
any one of a wide variety of materials such as metal, wood,
plastic, or the like depending on the production facilities
available, the economies to be effected, and/or the aesthetic
results to be obtained. Any one of the embodiments of the invention
may be fabricated of any one of the materials above discussed.
However, the FIG. 1 embodiment of the invention is found
particularly suitable for wood or metal fabrication, where
conventional milling equipment is available. The block 11 is formed
with desired channels 14 as described and illustrated with slots 16
extending from the front surface of the block into the channel
adjacent the vertically extending wall 24. Stop members 35 are
positioned at the lower end of the channel at a position selected
such as to insure the fact that the blocking members 30 will have
clearance with respect to the channel sidewalls when these locking
members 30 are against the stop members 35. The locking members 30
may similarly be fabricated of any material. Brass or white nylon
have been found to produce eminently satisfactory aesthetic
results. These locking members 30 are oriented in the channel with
the chamfered edge 32 adjacent the front wall of the channel, as
viewed in FIG. 3, and top locking members 37 are secured in
position. It will of course be obvious to those skilled in the art
that in lieu of a top locking pin 37, a cover plate similar to top
wall 42 of the FIG. 2 embodiment may be employed.
Similarly, though the FIG. 2 embodiment of the invention has been
particularly designed to facilitate plastic molding, it will be
apparent that the same construction may be fabricated of other
material such as wood or metal. In lieu of the stop pins 35, the
stop members are formed by the bottom wall 40 arranged to limit the
downward movement of the locking member 30 to a position such as to
insure clearance between the cylindrical surface of the locking
member 30 and the sidewalls of the channel when the locking member
is at its lowest position, as illustrated in FIG. 2.
In use, the holder is mounted on a wall or any other suitable
surface where it may be desired to store knives or the like, and
mounting is facilitated by virtue of the mounting flanges 24 and
25, through which appropriate fasteners such as screws or the like
are extended.
The knife is to be held is brought up against the face of the block
with the sharp edge of the knife blade aligned with slot 16, and
the handle of the knife slightly below the block at a distance such
as to permit upward movement of the knife with respect to the
block. The knife is brought into contact with the chamfered edge of
the locking member 30 and rolled upwardly as viewed in FIG. 1 so as
to bring the locking member 30 to a position in the channel such
that the clearance between the locking member 30 and the vertical
surface 24 is sufficient to accommodate the knife blade. In moving
the knife blade into the channel, it will be apparent, as viewed in
FIG. 4 that a honing action is provided by the chamfer of the
locking member against the cutting edge of the blade. The chamfered
edge additionally functions to provide an entry guide for the
blade. The blade when fully moved into the channel contacts the
cushioning surface 45 and is prevented for being dulled.
Where additional holding action is desired, the entire block may be
made of a ferromagnetic material and magnetized, or a magnetic
insert 50 may be employed. By the utilization of this magnetic
insert, or magnetization of the entire block, in the event that the
locking member should become jammed in the channel, desired holding
action may still be obtained as a result of the magnetic action of
the insert 50.
It will be apparent to those skilled in the art that gravity will
normally tend to move the locking member 30 downwardly over the
inclined surface 22 serving to wedge or sandwich the knife blade
between the cylindrical surface of the locking member 30 and the
vertical surface 24, thus providing a secure holding action against
the knife blade or the like.
