Description

[Detailed description of the invention] [Industrial application field] This invention relates to an ice shaver, and mainly relates to a simple ice shaver for general household use.

[Conventional technology]

As a simple ice shaver for general household use, it was developed as a device that could cut ice cubes without applying any special pressing force to press the ice cubes against the cutting blade.
Some of these are disclosed in Japanese Patent Publication No. 20683, Japanese Patent Publication No. 10229/1983, etc. In this device, a hopper is rotatably attached to a dish-shaped sharpener body, a spiral presser foot is formed on the hopper, and an ice block inlet is formed between the high end and the low end of the presser foot. The ice block is guided from the inlet to the lower surface of the presser foot of the hopper, and the ice block is pressed by the presser foot and pressed against the cutting blade of the sharpener body to be cut.

In ice shavers such as those described above, a rotating handle of the hopper is attached to the hopper. Since the hopper has a vertical axis of rotation about which it rotates, the handle is mounted to rotate in a horizontal plane. The hopper is also covered with a lid that rotates together with the hopper.

[The problem that the idea aims to solve]

When operating the ice shaver as described above, the handle must be rotated in a horizontal plane, which makes it difficult to operate.

In order to eliminate these drawbacks, we used a pair of bevel gears, the driving bevel gear is mounted on a horizontal shaft, and the driven bevel gear is integrated around the hopper, as is conventionally used in commercial ice shavers. It is possible to consider a configuration in which the gears are fixed to the gears and both gears are meshed.

When we prototyped an ice shaver with the above configuration,
Since the handle attached to the drive bevel gear is rotated in a vertical plane, it has the advantage of being easy to operate.
However, since the hopper is tilted due to the reaction force generated when the cutting blade scrapes the ice block, there is a drawback that the driven bevel gear integrated with the hopper tends to disengage.

Therefore, the technical object of this invention is to provide an ice shaver whose handle can be rotated in a vertical plane and whose gears mesh reliably.

[Means to solve the problem]

In order to solve the above-mentioned problem, this invention forms a slit 4 with a cutting blade 3 facing on the bottom surface of a dish-shaped sharpener main body 2 fixed on a support stand 1, and a slit 4 is formed inside the sharpener main body 2 so that it can rotate freely. In an ice shaver, a spiral presser foot 6 is formed on a hopper 5 attached to a hopper 5, and an ice block inlet 9 is provided between a high end 7 and a low end 8 of the presser foot 6. Horizontal axis 1 on support base 1
0, attach the drive bevel gear 11, and remove the sharpener body 2.
An annular driven bevel gear 14 is fitted around the opening 13 of the hopper 5 so as to be rotatable and to allow movement in the axial direction of the sharpener body 2.
and restricts the relative movement of the driven bevel gear 14 in the rotational direction, and is provided with a regulating piece 15 that protrudes above the driven bevel gear 14 at the meshing portion of both the bevel gears 11 and 14. It is something.

[Effect]

As the drive bevel gear 11 rotates, the driven bevel gear 14 that meshes with it rotates, and the driven bevel gear 14 also rotates.
The hopper 5 engaged with rotates. Due to the rotation of the hopper 5, the ice cubes inside are moved from the inlet 9 to the presser foot bottom 6.
, and passes over the cutting blade 3 of the sharpener main body 2 while being pressed by the presser foot bottom 6 . At this time, the ice block is cut.

Although the hopper 5 tilts due to the reaction force when cutting the ice block, the driven bevel gear 14 does not follow this because it is fitted separately. However, since the engagement relationship in the rotational direction between the two is maintained, the hopper 5 rotates. In addition, the above reaction force is applied to both bevel gears 1
1 and 14, the driven bevel gear 14
However, the upward movement of the driven bevel gear 14 is restricted by the restriction piece 15. Therefore, the meshing between both bevel gears 11 and 14 does not disengage, and the rotation of the driving bevel gear 11 is controlled by the driven bevel gear 14.
It is then conveyed to Hopper 5.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in FIGS. 1 and 2, the ice shaver of the embodiment has a support base 1 consisting of a pair of left and right legs 20, 21. A recess 22 is formed in the inner surface of both legs 20,21.

The shaft 10 is rotatably inserted into the bearing sleeve 28, and is prevented from coming off with a screw 32.

In addition, in order to attach the tooth portion 29 close to the sharpener main body 2, a notch 37 is provided on the outer surface of the leg 21 through which the tooth portion 29 and the outer circumference of the cover member 30 pass.
has been established.

A long hole 33 is formed in the collar 26 of the sharpener body 2 along the upper end of the leg 21, and a part of the teeth 29 faces the long hole 33 from below. .

The driven bevel gear 14 is formed in an annular shape, and has a sliding surface 34 (see FIG. 1) formed on its lower surface, and a downward guide wall 35 formed on the inner periphery of the sliding surface 34. The slide surface 34 mentioned above rests on the guide rail 27 of the sharpener main body 2 and freely rotates within a horizontal plane. Further, in the portion of the elongated hole 33, the driven bevel gear 14 is connected to the tooth portion 29 of the drive bevel gear 11.

At the engagement portion between the two, the collar 26 of the sharpener main body 2 is provided with a regulating piece 15 that projects inward. The regulating piece 15 is in contact with the upper surface of the driven bevel gear 14, and at that portion, the regulating piece 15 is in contact with the upper surface of the driven bevel gear 14.
restricts the upward movement of Also, the driven bevel gear 14
A plurality of engaging pieces 36 are protruded from the upper surface of the housing at regular intervals in the circumferential direction.

The hopper 5 has a cylindrical portion 38 and a collar portion 39 formed on the upper end thereof. Once formed on the inner circumferential surface of the cylindrical portion 38, a cylindrical central boss portion 40 is integrally formed on the inner circumferential edge of the helical presser foot 6. It is provided.

The presser foot bottom 6 is formed by two spiral plates that surround the boss part 40 half a circle at a time, and the slope of these spirals in the circumferential direction has a slope that gradually increases in the direction of rotation of the hopper 5. stipulated in Further, the high end 7 of one presser foot sole 6 and the low end portion 8 of the other presser foot sole 6 are vertically opposed to each other, and an ice block introduction port 9 is formed between them.

The lower surface of the presser foot 6 has fine radial lines 41.
is attached to provide frictional resistance against ice blocks. In addition, the collar portion 39 of the hopper 5
A plurality of engaging pieces 42 are provided protrudingly provided on the lower surface at regular intervals in the circumferential direction.

The cylindrical portion 38 of the hopper 5 is connected to the driven bevel gear 14.
At the same time, the center boss portion 40 is rotatably inserted into the fixed shaft 25 of the sharpener body 2, and the cap screw 43 is screwed into the upper end of the fixed shaft 25 to prevent the hopper 5 from coming off. Further, the engaging pieces 42 of the collar portion 39 engage with the respective engaging pieces 36 of the driven bevel gear 14, thereby preventing relative movement of the hopper 5 and the driven bevel gear 14 in the rotational direction. However, there is no mutual restriction in the axial direction (vertical direction) and they can move freely.
However, since the upward movement of the driven bevel gear 14 is partially restricted by the regulating piece 15, the hopper 5 and the driven bevel gear 14 are partially restrained as long as this regulating force is applied, but the other parts are restrained. is free.

A lid 44 is placed over the top surface of the hopper 5. The periphery of this lid 44 is, as shown in FIG.
It fits into the outer periphery of the collar 26 of the sharpener main body 2. Further, a sufficient gap is formed between the inner surface of the lid 44 and the hopper 5 so that the lid 44 does not come into contact with the hopper 5.

The ice shaver of the embodiment is constructed as described above, and its operation will be explained next.

After making ice to an appropriate size or putting an appropriate amount of crushed ice into the hopper 5 and covering it with the lid 44, the handle 31 is rotated.

As a result, the driving bevel gear 11 and the driven bevel gear 1
4 is rotated, and the hopper 5 engaged with the driven bevel gear 14 is rotated. When the hopper 5 rotates, the ice block inside is introduced from the introduction port 9 to the lower surface of the presser foot 6. It rotates while being pressed against the bottom surface of the shaver body 2 by the lower surface of the presser foot 6, and is scraped by the cutting blade 3 at the slit 4 portion, and the shaved ice falls from the slit 4.

When the ice block is shaved, the reaction force from the cutting blade 3 causes the fixed shaft 25 to rotate the boss portion 40 and the cap screw 4.
Due to the deflection of the third grade, the hopper 5 is lifted up in an inclined manner so that the cutting edge 3 is higher than the other parts. However, such movement of the hopper 5 is not directly transmitted to the driven bevel gear 14, which is separated from the hopper. The above reaction force is generated by both bevel gears 11 and 14.
Although the force is applied to the meshing portion of the driven bevel gear 14 and attempts to lift the meshing portion of the driven bevel gear 14, the force is received by the regulating piece 15, so that the driven bevel gear 14 does not become disengaged.

When scraping ice cubes in the manner described above, it is desirable to press the top surface of the lid 44 with the other hand in order to stabilize the support base 1. Since the lid 44 is not in contact with the hopper 5, even if force is applied to the lid 44, rotation of the hopper 5 will not be hindered.

[Effect of idea]

As mentioned above, this invention has the convenience of being able to rotate the handle 31 within the vertical plane by employing the drive bevel gear 11 that rotates within the vertical plane. In addition, by separating the driven bevel gear 14 from the hopper 5 and restricting relative movement only in the rotational direction, and by providing a regulating piece 15 at the meshing portion of the driven bevel gear 14 with the driving bevel gear 11, it is possible to cut ice blocks. This has the effect that the driven bevel gear 14 does not become disengaged due to the reaction force of the engine, and can be operated smoothly.
