Description

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 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.

[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.

[Embodiments]

[0023]
Referring to Figs., the following description will discuss a slicer 1 relating to one embodiment in accordance with the present invention. Additionally, in the following description, terms "front" and "rear" correspond to the front side and the rear side in a slicing direction that is coincident with a feeding direction of a material to be sliced at the time of slicing the material to be sliced. Moreover, terms "up" and "down"
correspond to the upper side and the downward side in a direction perpendicular to the slicer.
Furthermore, terms "right" and "left" correspond to the right side and the left side facing the slicing direction.

[0024]

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]

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]

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 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 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.

[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.

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 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.

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.
