The bolt receiving hole 17 and the nut mounting hole 18 are limited to the case where the bolt receiving hole 17 is provided above (front side) the slicing blade 20 and the nut mounting hole 18 is provided below (back side) the slicing blade 20. Instead, the bolt accommodation hole 17 may be provided below (back side) the slicing blade 20, and the nut mounting hole 18 may be provided above (front side) the slicing blade 20.

  Next, the slice blade fixing mechanism 100 will be described with reference to FIGS. 5 to 7 show the frame 10, the slice blade 20, and the slice blade fixing mechanism 100 in a simplified manner. FIG. 5 is a diagram illustrating a state before the slice blade 20 is attached to the frame 10. FIG. 6 is a view showing a state in which the slice blade 20 is attached to the frame 10. FIG. 7 is a longitudinal sectional view of the slicing blade fixing mechanism 100.

  As shown in FIG. 5, the slicing blade fixing mechanism 100 includes an embedded nut 110 housed in the nut mounting hole 18 and a fastening bolt 120 that can be screwed into the embedded nut 110.

  The embedded nut 110 is formed in a cylindrical shape, and a screw portion (not shown) is provided around the inner peripheral surface. The embedded nut 110 only needs to have a higher hardness than the ABS resin frame 10, and is preferably made of metal such as brass. The embedded nut 110 is not limited to a cylindrical shape, and may be a polygonal column shape, for example.

  The embedded nut 110 is embedded in the frame 10, and in the present embodiment, the embedded nut 110 is insert-molded.

  The fastening bolt 120 includes a head portion 121 having a top surface formed horizontally and a shaft portion 122 around which a screw portion (not shown) is provided on the outer periphery.

  As shown in FIG. 6, after inserting the edge part of the slicing blade 20 into the slit 11a, the shaft part 122 of the fastening bolt 120 is inserted into the bolt hole 21 of the slicing blade 20, and the fastening bolt 120 is inserted into the embedded nut. By being engaged with 110, the slicing blade 20 is fixed to the frame 10.

  According to this configuration, when the embedded nut 110 and the fastening bolt 120 are screwed together, the embedded nut 110 is compared with a slicer in which a screw hole having a lower hardness than the conventional fastening bolt tends to wear significantly. Therefore, even when the slicing blade 20 is repeatedly attached and detached, the fastening failure of the fastening bolt 120 is suppressed, and the fastening bolt 120 can fix the slicing blade 20 over a long period of time.

  Further, since the embedded nut 110 is firmly fixed in the frame 10 by insert molding, the embedded nut 110 is prevented from idling in the nut mounting hole 18 when the fastening bolt 120 is loosened. The fastening bolt 120 can securely fix the slicing blade 20.

  Furthermore, since the embedded nut 110 is locally disposed on a part of the support arm 11, the durability of the slicer 1 can be improved at a low cost.

  As shown in FIG. 7, the head 121 of the fastening bolt 120 is preferably accommodated in the bolt accommodation hole 17 of the frame 10. In particular, it is preferable that the top surface of the head 121 is accommodated in a state of being substantially flush with the surface 10 a of the frame 10. Thereby, since the head 121 of the fastening bolt 120 comes into contact with the material to be sliced and the fastening bolt 120 is prevented from being unintentionally loosened due to an external force, the fastening bolt 120 reliably secures the slicing blade 20. Can be fixed. Further, the slicer 1 can be used in a sanitary manner by suppressing the scrap of the material to be sliced from remaining in the bolt housing hole 17.

  In this manner, the slicer 1 according to the present embodiment suppresses the fastening failure of the fastening bolt 120 due to repeated tightening of the fastening bolt 120 and improves the durability of the slicer 1. It can be used for a long time.

  As a modified example of the slicing blade fixing mechanism 100, an embedded nut 110 may be separately joined to the frame 10 after the frame 10 is injection molded. The structure of the slicing blade fixing mechanism 100 according to such a modification will be described with reference to FIGS. FIGS. 8A and 8B are views showing the embedded nut 110 used in the slicing blade fixing mechanism 100 according to the modification, where FIG. 8A is a plan view and FIG. 8B is a side view. FIGS. 9A and 9B are views showing the fastening bolt 120 screwed with the embedded nut 110 of FIG. 8, wherein 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 slice blade fixing mechanism 100 according to the modification. In addition, about the member which is common with the slice blade fixing mechanism 100 which concerns on the Example mentioned above, a common code | symbol is attached | subjected and the overlapping description is abbreviate | omitted.

  The embedded nut 110 and the fastening bolt 120 are made of steel, but any material may be used as long as it has a desired durability.

  The embedded nut 110 includes a cylindrical shaft portion 111, an inner peripheral side screw portion 112, an outer peripheral side screw portion 113, and a head portion 114. The inner peripheral side screw part 112 is provided around the inner peripheral surface 111 a of the shaft part 111. The outer peripheral side screw part 113 is provided around the outer peripheral surface 111 b of the shaft part 111. In the present embodiment, the inner diameter of the inner peripheral side screw portion 112 is set to 4 mm, and the outer diameter of the outer peripheral side screw portion 113 is set to 8 mm. The head 114 is formed with a screw hole 114a that is formed in a cross shape in plan view and can be engaged with a driver or the like.

  The fastening bolt 120 includes a screw portion 123 provided around the outer periphery of the shaft portion 122. In this embodiment, the outer diameter of the screw portion 123 is set to 4 mm. The head 121 is formed with a screw hole 121a that is formed in a cross shape in a plan view and that can be engaged with a driver or the like.

  The bolt 110 and the embedded nut 120 fix the frame 10 made of ABS resin and the slice blade 20 made of stainless steel while being arranged on the same axis L. Specifically, the embedded nut 120 is screwed into the nut mounting hole 18 from below the frame 10, the fastening bolt 120 is inserted into the bolt hole 21 of the slicing blade 20, and the inside of the embedded nut 120 is inserted from above the frame 10. Screwed into the circumferential screw portion 112.

  Next, a procedure for fixing the frame 10 and the slice blade 20 using the slice blade fixing mechanism 100 will be described with reference to FIGS. Note that the embedded nut 110 in FIG. 11 is shown with a part of the tip cut away.

  As shown in FIG. 11A, the embedded nut 110 is disposed below the vertical direction H and the fastening bolt 120 is disposed above the frame 10 and the slice blade 20. When the frame 10 is disposed above the slicing blade 20, the embedded nut 110 is disposed above the fastening bolt 120.

  The embedded nut 110 is screwed into the frame 10 and the slicing blade 20 as shown in FIG. 11 (b) when screwed into the nut mounting hole 18 of the frame 10 with a screwdriver or the like and screwed by a predetermined amount. . At this time, since the shaft portion 111 of the embedded nut 110 is formed to have a tapered diameter from the proximal end to the distal end, when the embedded nut 110 is attached to the frame 10, the embedded nut 110 can be screwed into the nut mounting hole 18 with a small force.

  Next, as shown in FIG. 11 (c), the fastening bolt 120 is screwed into the inner peripheral side threaded portion 112 of the embedded nut 110 with a screwdriver or the like, so that the frame 10 and the slice blade 20 are connected to the embedded nut. 110 and the fastening bolt 120 are fixed so as to be sandwiched from above and below. As a result, the bolt 120 is screwed with the embedded nut 110 without being screwed to the soft frame 10, so that even when the bolt 120 is repeatedly attached and detached, the fastening force due to deformation of the frame 10 or the like is reduced. The decrease can be suppressed.

  In this way, the fastening means 100 according to the present modification produces the frame 10 including the embedded nut 110 by screwing the embedded nut 110 into the nut mounting hole 18 of the frame 10 and embedding it. As compared with the above, the human cost and the time cost required for manufacturing the frame 10 can be reduced. Further, the embedded nut 110 and the fastening bolt 120 sandwich the frame 10 and the slice blade 20 from above and below, so that the frame 10 and the slice blade 20 can be firmly fixed.

  The present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.
