SLICER WITH DETACHABLE BLADE
BACKGROUND OF THE INVENTION
Field of the Invention
[0001] The present invention relates to a slicer for slicing a material to
be sliced, such as
a vegetable, fruit or the like, and in particular concerns a slicer in which a
slicing blade is freely
detachably attached to a frame.
Description of the Related Art
[0002] Conventionally, as a slicer for use in easily slicing various
materials to be sliced,
such as vegetables, fruits or the like, into sliced pieces having a desired
width, such as a slicer
has been used in which the material to be sliced is reciprocally moved forward
and reward in the
slicing direction so as to slice the material to be sliced by using a slicing
blade.
[0003] As a conventional slicer, such a slicer has been known which is
provided with a
frame made of resin having a pair of right and left supporting arms, a slicing
blade that is freely
detachably attached to the supporting arms, a fixed slicing blade that is
disposed on the front side
of the slicing blade and passed between the paired right and left supporting
arms, and a movable
supporting plate disposed on the rear side of the slicing blade (see JP-A No.
2004-338069).
[0004] In this slicer, the slicing blade is freely detachably attached to a
frame by using
bolts that are meshed with screw holes formed by a tapping process at desired
positions in
accordance with attaching positions of the slicing blade. With this
arrangement, since a slicing
blade that has been used for a long time and worn can be sharpened, or since a
used slicing blade
can be exchanged to a new slicing blade, it is possible to continuously use a
slicer for a long
period of time.
[0005] [Patent Document 1] JP-A No. 2004-338069
[0006] In the case of the above mentioned slicer, however, the screw hole
is worn out
due to repeated attaching and detaching processes of the slicing blade, to
sometimes cause a so-
called fastening failure of the bolt in which the bolt fails to be desirably
meshed with the screw
hole to cause an unstable engaged state of the bolt with the screw hole. When
the screw hole is
further worn out to cause a failure in securing the slicing blade to the
frame, the resulting
problem is that the slicer can no longer be used thereafter.

[0007] For this reason, technical problems are raised in an attempt to
provide a slicer that
can be used for a long period of time by suppressing the fastening failure of
the fastening bolt for
use in securing the slicing blade to the frame, and the object of the present
invention is to solve
these problems.
SUMMARY OF THE INVENTION
[0008] In accordance with a general aspect, there is provided a slicer
having: a slicing
blade for slicing a material to be sliced; a frame made of resin having a pair
of supporting arms
provided with slits for housing two ends of the slicing blade; and a slicing
blade fixing
mechanism for securing two ends of the slicing blade to the paired supporting
arms, and in this
structure, the slicing blade fixing mechanism is provided with an embedded nut
made of metal
that is disposed on one of the surface side and the rear side of the slicing
blade, and also disposed
inside a nut attaching hole that is communicated with the slit, and a
fastening bolt that is
disposed on the front side or the rear side of the slicing blade, and is
meshed with the embedded
nut, while being inserted into a bolt hole formed on an end portion of the
slicing blade.
[0009] In accordance with this structure, since the fastening bolt is
meshed with an
embedded nut having a hardness higher than that of a conventional frame mode
of resin so that it
is possible to prevent one of the fastening bolt and the embedded nut from
wearing extremely in
comparison with the other, and even in the case when the fastening bolt is
repeatedly tightened
and loosened, it is possible to suppress the fastening failure in the
fastening bolt, and the
fastening bolt can secure the slicing blade for a long period of time.
Moreover, since the
embedded nut is locally disposed on one portion of the supporting arm, it
becomes possible to
improve the durability of the slicer at low costs.
[0010] In accordance with a further aspect, there is provided a slicer in
which the
embedded nut is insert-molded with the frame and anchored thereto.
[0011] In accordance with this structure, since the embedded nut is firmly
anchored to
the frame, it is possible to prevent the embedded nut from idling inside the
nut attaching hole at
the time of tightening/loosening the fastening bolt so that the fastening bolt
can positively secure
the slicing blade.
[0012] In accordance with another aspect, there is provided a slicer in
which the
embedded nut is disposed on the rear side of the slicing blade, and the
fastening bolt is disposed
CA 2895009 2018-10-24

on the surface side of the slicing blade, with the head portion of the
fastening bolt being housed
in a bolt housing hole formed on the surface of the supporting arm.
[0013] In accordance with this structure, since the fastening bolt is
housed in the bolt
attaching hole, without the head portion of the fastening bolt being made to
protrude from the
surface of the frame, it is possible to prevent the fastening bolt from being
undesirably loosened
by receiving an external force caused when the head portion of the fastening
bolt is made in
contact with a material to be sliced, or the like so that the fastening bolt
can positively secure the
slicing blade.
[0014] In accordance with a still further general aspect, there is provided
a slicer in
which, the head portion of the fastening bolt is housed in the bolt housing
hole, with the top
surface of the head portion being kept substantially on the same level as the
surface of the
supporting arm.
[0015] In accordance with this structure, since the top surface of the
fastening bolt is
position-determined on substantially the same level as that of the surface of
the supporting arm,
it is possible to prevent the fastening bolt from being undesirably loosened
by receiving an
external force, making it possible to positively secure the slicing blade and
also to suppress cut
chips of the material to be sliced from remaining inside the bolt housing
hole; thus, the slicer can
be used sanitarily.
[0016] In accordance with another aspect, there is provided a slicer in
which the
embedded nut includes a shaft portion which is cylindrically formed, an inner-
periphery-side
threaded portion which is formed on an inner periphery of the shaft portion
and can be meshed
with the fastening bolt inserted into the shaft portion from a distal end to a
proximal end, and an
outer-periphery-side screw portion which is formed on an outer periphery of
the shaft portion
and can be meshed with the nut attaching hole.
[0017] According to the structure, the fastening bolt and the embedded nut
sandwich the
frame and the slicing blade from both the surface side and the rear side to
make it possible to
strongly fix the frame and the slicing blade to each other. Furthermore, the
embedded nut is
embedded to be screwed into the nut attaching hole to make it possible to
reduce a personnel cost
and a temporal cost required to manufacture a frame in comparison with a case
in which a frame
including an embedded nut is manufactured.
CA 2895009 2018-10-24

[0018] In accordance with another general aspect, there is provided a
slicer in which the
shaft portion of the embedded nut is formed to be reduced in diameter such
that the shaft portion
is tapered from the proximal end to the distal end.
[0019] According to the structure, when the embedded nut is screwed into
the nut
attaching hole, since a resistance generated when the embedded nut is screwed
into the nut
attaching hole is reduced, the embedded nut can be easily attached.

[0020]
The slicer in accordance with the present invention makes it possible to
suppress a fastening failure of the fastening bolt caused by repeatedly
tightening and
loosening the fastening bolt, and consequently to improve the durability of
the slicer;
5 thus, it becomes possible to use the slicer for a long period of time.

As shown in Figs. 1 and 2, the slicer 1 is provided with a frame 10 having a
pair
of right and left supporting arms 11, a slicing blade 20 that is secured to
the frame 10 by
a slicing blade fixing mechanism 100 so as to slice the material to be sliced,
a fixed
supporting plate 30 that is disposed on the front side of the slicing blade
20, a movable
supporting plate 40 disposed on the rear side of the slicing blade 20, a slice
width
adjusting mechanism 50 that position-determines the movable supporting plate
40 at a
desired position in the vertical direction H, and a grip 60 that is fastened
to the frame 10
by using bolts, not shown. The frame 10, the fixed supporting plate 30, the
movable
supporting plate 40 and the grip 60 are respectively made of ABS resin, and
produced
by an injection molding process. The slicing blade 20 is made of stainless
steel. Note
that the material of the frame 10 is not limited to ABS resin, and any
material such as
acrylate resin, polypropylene resin, or polyethylene resin may be used.
[0025]
The slicer 1 is designed such that when a user reciprocally moves a material
to
be sliced in a slicing direction S while pressing the material to be sliced
onto the
movable supporting plate 40, the material to be sliced is sliced into sliced
pieces having
a thickness in accordance with a gap between the slicing blade 20 and the
movable
supporting plate 40. The sliced pieces are discharged from the rear side of
the slicer 1.
[0026]
The slicing blade 20 is extended diagonally relative to the width direction W
of
the frame 10. On the two ends of the slicing blade 20, bolt holes 21 to be
described
later are respectively formed. The slicing blade 20 is fastened to the frame
10 by
fastening bolts 120 inserted through the bolt holes 21.
[0027]
The fixed supporting plate 30 is disposed between a pair of supporting arms
11,
and integrally attached to the supporting arms 11. On the surface 30a of the
fixed
supporting plate 30, 11 rows of groove portions 31 are engraved and formed
side by
side in the width direction W in an extended manner in the slicing direction
S. By
forming the groove portions 31 on the surface 30a of the fixed supporting
plate 30, the
fixed supporting plate 30 and the material to be sliced are made in contact
with each
other with a reduced area so that the material to be sliced can be
reciprocally moved
smoothly. The depth dimension of the groove portions 31 may be desirably
determined.

[0028]
The movable supporting plate 40 is provided with a front pin 41 to be guided,
which is formed on the front side of a side face 40a so as to protrude
therefrom, and a
rear pin 42 to be guided, which is formed on the rear side of the side face
40a so as to
protrude therefrom. The front pin 41 to be guided is meshed with a front guide
groove
14 to be described later of the supporting arm 11. The rear pin 42 to be
guided is
meshed with a rear guide groove 15 to be described later of the supporting
arm. The
movable supporting plate 40 is raised/lowered in accordance with the shapes of
the
front guide groove 14 and the rear guide groove 15 so that wobbling and
twisting of the
movable supporting plate 40 are regulated.
[0029]
The movable supporting plate 40 is provided with 11 rows of groove portions 43
that are engraved and formed on a surface 40b so as to be placed side by side
in the
width direction W in an extended manner in the slicing direction S. By forming
the
groove portions 43, the ground contact area between the movable supporting
plate 40
and the material to be sliced is reduced correspondingly so that the sliding
resistance
upon slicing the material to be sliced is reduced.
[0030]
The slice width adjusting mechanism 50 is capable of adjusting the slice width
by raising/lowering the movable supporting plate 40 relative to the slicing
blade 20.
The slice width adjusting mechanism 50 is constituted by a stay 52 that is
provided with
a screw receiving hole 51 and passes between the paired supporting arms 11,
and a
slice width adjusting dial 53 that can be meshed with the screw receiving hole
51.
[0031]
The screw receiving hole 51, which is disposed in the center of the stay 52,
is
designed to be placed below the movable supporting plate 40, when the stay 52
is
attached to the frame 10.
[0032]
The stay 52 is detachably attached to the frame 10, and when bolts B1 are
meshed with a screw hole 11d of the frame 10 and screw hole 52a of the stay
52, the
stay 52 is secured onto the frame 10.
[0033]
CA 02895009 2015-06-18

The slice width adjusting dial 53 is provided with a main body unit 53a having
a
hollow cylindrical shape, a screw portion 53b formed on an outer peripheral
surface of
the main body unit 53a and a handle 53c formed on the base end of the main
body unit
53a.
[0034]
When the user holds the handle 53c and rotates with the screw portion 53b
being meshed with the screw receiving hole 51, the slice width adjusting dial
53 is
raised/lowered relative to the stay 62. Thus, the movable supporting plate 40
is
raised/lowered while maintaining its horizontal attitude, with its rear
surface being
supported by the slice width adjusting dial 63, so that the gap between the
slicing blade
and the movable supporting plate 40, that is, the slice width, can be
desirably
adjusted.
[0035]
The grip 60 is provided with a grip portion 61 to be held by the user, and
15 connecting portions 62 that are connected to the rear ends of the paired
right and left
supporting arms 11 that are formed on the two ends of the grip portion 61. In
the
present embodiment, the grip 60 is fastened by bolts, not shown, with a tip
convex
portion 63 being fitted to a rear end concave portion 12 of each of the
supporting arms
11. Additionally, the grip 60 is not limited by a structure to be fastened
with bolts as
20 long as it is secured to the supporting arms 11, and the grip 60 may be
integrally formed
with the supporting arms 11.
[0036]
Additionally, an exchange blade, not shown, may be attached to the slicer 1.
The exchange blade is attached between the slicing blade 20 and the movable
.. supporting plate 40. The exchange blade is provided with a plurality of
teeth formed on
the exchange blade in the longitudinal direction, and the two ends thereof are
supported
by the frame 10, with these teeth facing upward. The exchange blade is used
for
forming notches on the material to be sliced along the slicing direction S in
accordance
with the gap of the teeth, and by using the slicing blade 20 and the exchange
blade in
combination with each other, the material to be slice can be sliced into stick
shapes and
rectangular strip shapes having various sizes.
[0037]
CA 02895009 2015-06-18
As shown in Fig. 3 as well as Figs. 4A, 4B, and 4C, the frame 10 is provided
with the paired right and left supporting arms 11 that are attached to the two
ends of the
fixed supporting plate 30 in the width direction. Additionally, reference
numeral 12 in
Fig. 3 and Figs. 4A to 4C represents a rear end concave portion capable of
being
5 meshed with a connecting convex portion 63 of the grip 60, and reference
numeral 13
represents a screw hole that is meshed with a bolt, not shown, inserted
through each of
the screw holes 52a of the stay 52.
[0038]
On each of the supporting arms 11, a front guide groove 14 and a rear guide
10 groove 15 are formed on an inner side face 11 a as concave portions. The
front guide
groove 14 and the rear guide groove 15 are formed in a manner so as to extend
diagonally from the rear side toward the front side in the slicing direction S
upward in the
vertical direction H. The front guide groove 14 is meshed with the front pin
41 to be
guided of the movable supporting plate 40. Moreover, the rear guide groove 15
is
meshed with the rear pin 42 to be guided of the movable supporting plate 40.
Additionally, the shapes of the front guide groove 14 and the rear guide
groove 15 may
be desirably determined. Since the lower portion of the front guide groove 14
and the
lower portion of the rear guide groove 15 are formed as openings, the movable
supporting plate 40 can be detachably attached to the frame 10.
[0039]
On each of the supporting arms 11, a slit 16 for use in housing the end
portion
of the slicing blade 20 is formed so as to penetrate in the width direction W.
The slit 16
is formed diagonally relative to the width direction W in accordance with the
shape of the
slicing blade 20.
[0040]
Moreover, each of the supporting arms 11 is provided with a bolt housing hole
17 disposed above the slit 16 and a nut attaching hole 18 disposed below the
slit 16.
The bolt housing hole 17 is formed so as to penetrate the supporting arm 11
from the
surface 10a of the frame 10 to the slit 16. The nut attaching hole 18 is
formed coaxially
with the bolt housing hole 17 as a concave portion that communicates with the
slit 16 so
as to have a diameter smaller than that of the bolt housing hole 17.
Additionally, with
respect to the bolt housing hole 17 and the nut attaching hole 18, not limited
to the
CA 02895009 2015-06-18
11
structure in which the bolt housing hole 17 is formed above (surface side) the
slicing
blade 20, with the nut attaching hole 18 being formed below (rear side) of the
slicing
blade 20, the bolt housing hole 17 may be below (rear side) of the slicing
blade 20, with
the nut attaching hole 18 being formed above (surface side) the slicing blade
20.
[0041]
Next, referring to Figs. 5 to 7, the following description will discuss the
slicing
blade fixing mechanism 100. Figs. 5 to 7 are views that schematically show the
frame
10, the slicing blade 20 and the slicing blade fixing mechanism 100. Fig. 5 is
a view
showing a state before the slicing blade 20 is attached to the frame 10. Fig.
6 is a view
showing a state in which the slicing blade 20 is attached to the frame 10.
Fig. 7 is a
cross-sectional view showing the slicing blade fixing mechanism 100.
[0042]
As shown in Fig. 5, the slicing blade fixing mechanism 100 is constituted by
an
embedded nut 110 housed in the nut attaching hole 18 and a fastening bolt 120
capable
of being meshed with the embedded nut 110.
[0043]
The embedded nut 110 is formed into a cylindrical shape, and a threaded
portion, not shown, is formed on the inner peripheral surface. The embedded
nut 110
may be made of any material having a hardness higher than that of the frame 10
made
of the ABS resin, and is preferably made of, for example, metal, such as
brass. Not
limited to the cylindrical shape, the embedded nut 110 may be formed into, for
example,
a polygonal pillar shape.
[0044]
The embedded nut 110 is embedded in the frame 10, and in the present
embodiment, the embedded nut 110 is insert-molded.
[0045]
The fastening bolt 120 is provided with a head portion 121 with a top surface
formed horizontally, and a shaft portion 122 having a screw portion, not
shown, formed
on the outer periphery thereof.
[0046]
As shown in Fig. 6, after the end portion of the slicing blade 20 has been
inserted into the slit 11a, the shaft portion 122 of the fastening bolt 120 is
inserted
CA 02895009 2015-06-18
12
through the bolt hole 21 of the slicing blade 20, with the fastening bolt 120
being
meshed with the embedded nut 110, so that the slicing blade 20 is secured onto
the
frame 10.
[0047]
In accordance with this structure, by allowing the embedded nut 110 to be
meshed with the fastening bolt 120, the embedded nut 110 is prevented from
wearing in
comparison with a conventional slicer in which the screw hole having a lower
hardness
than that of the fastening bolt tends to wear extremely; therefore, even in
the case when
the slicing blade 20 is attached/detached repeatedly, it is possible to
suppress a
fastening failure of the fastening bolt 120 so that the fastening bolt 120 can
secure the
slicing blade 20 for a long period of time.
[0048]
Moreover, since the embedded nut 110 is tightly anchored in the frame 10 by
the insert molding process, the embedded nut 110 of the fastening bolt 120 is
prevented
from idling inside the nut attaching hole 18 at the time of tightening and
loosening the
fastening bolt 120 so that the fastening bolt 120 makes it possible to
positively secure
the slicing blade 20.
[0049]
Furthermore, since the embedded nut 110 is locally disposed on one portion of
the supporting arm 11, it becomes possible to improve the durability of the
slicer 1 at low
costs.
[0050]
As shown in Fig. 7, the head portion 121 of the fastening bolt 120 is
preferably
housed inside the bolt housing hole 17 of the frame 10. In particular, it is
more
preferably housed therein, with the top surface of the head portion 121 being
kept
substantially on the same level as the surface 10a of the frame 10. Thus,
since it is
possible to prevent the fastening bolt 120 from being undesirably loosened by
receiving
an external force caused when the head portion 121 of the fastening bolt is
made in
contact with a material to be sliced, or the like, the fastening bolt 120
makes it possible
to positively secure the slicing blade 20. Moreover, by preventing cut chips
of the
material to be sliced from remaining inside the bolt housing hole 17, it
becomes possible
to use the slicer 1 sanitarily.
CA 02895009 2015-06-18
13
[0051]
In this manner, the slicer 1 in accordance with the present embodiment makes
it possible to prevent a fastening failure of the fastening bolt 120 caused by
repeatedly
tightening and loosening the fastening bolt 120, and consequently to improve
the
durability of the slicer 1; thus, it becomes possible to use the slicer 1 for
a long period of
time.
[0052]
As a modification of the slicing blade fixing mechanism 100, the embedded nut
110 may be additionally joined to the frame 10 produced by an injection
molding process.
The structure of the slicing blade fixing mechanism 100 according to the
modification will
be described with reference to Figs. 8 to 10. Figs. 8A and 83 are drawings
showing
the embedded nut 110 used in the slicing blade fixing mechanism 100 according
to the
modification. Fig. 8A is a plan view, and Fig. 8B is a side view. Figs. 9A and
9B are
drawings showing the fastening bolt 120 meshed with the embedded nut 110 in
Figs. 8A
and 8B. Fig. 9A is a plan view, and Fig. 9B is a side view. Fig. 10 is an
exploded
perspective view schematically showing a fixing structure of the slicing blade
fixing
mechanism 100 according to the modification. The same reference numerals as in
the
embodiment described above denote the members common in the slicing blade
fixing
mechanism 100 according to the embodiment, respectively, and a repetitive
description
will not be performed.
[0053]
The embedded nut 110 and the fastening bolt 120 are made of steel, however,
may be made of any material as long as the material has desired durability.
[0054]
The embedded nut 110 includes a cylindrical shaft portion 111, an inner-
periphery-side threaded portion 112, an outer-periphery-side screw portion
113, and a
head portion 114. The inner-periphery-side threaded portion 112 is formed on
an inner
peripheral surface 111a of the shaft portion 111. The outer-periphery-side
screw
portion 113 is formed on an outer peripheral surface 111b of the shaft portion
111. The
inner diameter of the inner-periphery-side threaded portion 112 and the outer
diameter
of the outer-periphery-side screw portion 113 are set to 4 mm and 8 mm,
respectively.
CA 02895009 2015-06-18

In the head portion 114, a screw hole 114a which is formed in the shape of
cross in
planar view and can be fitted on a screwdriver or the like is formed.
[0055]
The fastening bolt 120 includes a screw portion 123 formed on the outer
periphery of the shaft portion 122. In the embodiment, the outer diameter of
the screw
portion 123 is set to 4 mm. In the head portion 121, a screw hole 121a which
is formed
in the shape of cross in planar view and can be fitted on a screwdriver or the
like is
formed.
[0056]
The bolt 120 and the embedded nut 110 fix the frame 10 made of ABS resin
and the slicing blade 20 made of stainless steel to each other while being
arranged on
the same axial line L. More specifically, the embedded nut 110 is screwed into
the nut
attaching hole 18 from the bottom of the frame 10, and the fastening bolts 120
are
respectively inserted into the bolt holes 21 of the slicing blade 20 and
meshed with the
inner-periphery-side threaded portion 112 of the embedded nut 110 from the top
of the
frame 10.
[0057]
A procedure of fixing the frame 10 and the slicing blade 20 to each other by
using the slicing blade fixing mechanism 100 will be described below with
reference to
Figs. 11A to 110. Note that the embedded nut 110 in Figs. 11A to 11C is
illustrated
such that the proximal end of the embedded nut 110 is partially cut away.
[0058]
As shown in Fig. 11A, the embedded nut 110 and the fastening bolt 120 are
arranged on the lower side and the upper side in the vertical direction H to
sandwich the
frame 10 and the slicing blade 20. When the frame 10 is arranged above the
slicing
blade 20, the embedded nut 110 is arranged above the fastening bolt 120.
[0059]
When the embedded nut 110 is screwed into the nut attaching hole 18 of the
frame 10 with a screwdriver or the like and screwed by a predetermined length,
as
shown in Fig. 11B, the embedded nut 110 is meshed with the frame 10 and the
slicing
blade 20. At this time, the shaft portion 111 of the embedded nut 110 is
formed to be
reduced in diameter such that the shaft portion 111 is tapered from the
proximal end to
CA 02895009 2015-06-18
the distal end. For this reason, when the embedded nut 110 is to be attached
to the
frame 10, the embedded nut 110 can be screwed into the nut attaching hole 18
by weak
force.
[0060]
5 As shown in Fig. 11C, the fastening bolt 120 is meshed with the inner-
periphery-side threaded portion 112 of the embedded nut 110 with a screwdriver
or the
like to fix the frame 10 and the slicing blade 20 to each other such that the
frame 10 and
the slicing blade 20 are vertically sandwiched between the embedded nut 110
and the
fastening bolt 120, In this manner, since the bolt 120 is meshed with the the
embedded
10 nut 110 without being meshed with the soft frame 10, even though the
bolt 120 is
repeatedly attached and detached, fastening force can be suppressed from being
deteriorated due to deformation or the like of the frame 10.
[0061]
In this manner, in the fastening means 100 according to this modification, the
15 embedded nut 110 is embedded to be screwed into the nut attaching hole
18 of the
frame 10 to make it possible to reduce a personnel cost and a temporal cost
required to
manufacture the frame 10 in comparison with a case in which the frame 10
including the
embedded nut 110 is manufactured. Furthermore, the embedded nut 110 and the
fastening bolt 120 vertically sandwich the frame 10 and the slicing blade 20
to make it
possible to tightly fix the frame 10 and the slicing blade 20 to each other.
[0062]
In the present invention, various modifications may be made within the scope
without departing from the gist of the present invention, and those
modifications are of
course included within the scope of the present invention.
