DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A description will be given below with reference to the drawings. The hand-held ice shaving device according to the embodiment is formed to have a size and shape that can be easily held in one hand and to be lightweight.

The container portion 1 for storing ice has a bottomed cylindrical shape, and its bottom plate 18 is of a raised bottom type, and a lower portion 19 therebelow.
However, it is a stand for standing upright. The bottom plate 18 is provided with a radial ice removing slit 20, and the cutter 2 is attached along the edge of the slit 20.

The main body 3 has a hollow cylindrical shape similar to that of the container portion 1 described above, and includes a lower portion 3A and an upper portion 3B connected to the container portion 1 (see FIGS. 1 and 2).

The connecting portion between the container portion 1 and the lower portion 3A of the main body is provided with a step so that they are fitted to each other at the connection opening, and the engaging projection 22 is provided on the outer peripheral surface of the fitting portion 21 on the inner side. Since the engaging recesses 24 are formed on the inner peripheral surface of the outer fitting portion 23, the container portion 1 and the main body lower portion 3 can be attached and detached (FIG. 3).

A rotating body 4 for pressing ice from above is provided at the bottom of the main body 3, and the rotating body 4 is provided integrally with a screw shaft 5 fixed at the center so as to be rotatable around the axis and vertically movable. To be On the lower surface of the rotating body 4, claws 25 for pressing ice are radially arranged at a plurality of locations, and recesses 46 are provided between the rows of claws to facilitate pressing small ice. Reference numeral 26 denotes a set screw, which fixes the rotating body 4 to the shaft end of the screw shaft.

The screw shaft 5 can move the rotating body 4 to an arbitrary height position according to the amount of ice, and it is necessary to press the ice by the rotating body 4 at the time of the ice scraping operation. A well-known split nut 7 consisting of two members with a female screw 27 cut is attached to the lower portion 3A of the main body. Two
Reference numeral 8 denotes a pocket provided in the lower portion 3A of the main body for accommodating the split nut 7.

The split nut 7 can be operated externally, and an operating body 14 for that purpose is annular and is rotatably externally fitted to a cylindrical guide surface 29 provided so as to project above the lower portion 3A of the main body. The split nut 7 is formed with a chamfered cam groove 30 having different radial lengths at the start end and the end. The lower surface of the operating body 14 is engaged with the cam groove 30. Since the cam pin 31 projects, the split nut 7 can be screwed into the screw shaft screw portion 6 by the rotation of the operating body 14 and can be separated from the screw portion 6 by the reverse rotation (FIG. 6).
Reference numeral 32 denotes a cover of the split nut 7.

To drive the screw shaft 5, a drive gear 34
Is arranged on the lower surface of the main body upper part 3B, and the gear 34 is attached to the motor 8 incorporated in the main body upper part 3B.
Is connected via a gear (FIGS. 7 and 8).

A power supply circuit 9 for driving the motor 8 is incorporated in the main body 3. The power supply circuit 9 can move up to a fixed contact 12 installed in a notch 36 formed in the cylindrical guide surface 29 of the lower part 3A of the main body, and a fixed position where the contact 12 can be contacted, and the spring 15 constantly operates. Movable contact 1 provided on sliding shaft 16 that receives a downward biasing force
1 is provided with a switch 10 (FIG. 5).

The sliding shaft 16 is disposed inside and near the outer periphery of the lower portion 3A of the main body (FIGS. 3 and 4), and can be engaged with the cam portion 17 formed at the upper end of the container portion 1. .
That is, the sliding shaft 16 is in the cam concave portion 17a when the container portion 1 is applied, but is pushed up by the cam inclined surface 17b while the engaging protrusion 22 is completely engaged with the engaging concave portion 24, and is completely engaged. When they are fitted together, they are set in a fixed position by the set surface 17c (FIG. 5 (b)).

On the other hand, a switch piece 13 for closing the switch 10 is provided on the operating body 14 for screwing the split nut 7. The switch piece 13 is provided so that it can be pushed inward from the peripheral surface of the operating body 14. When pressed, the contact point is closed, and when the push button is stopped, the contact point is opened immediately. However, it can be pushed only when the operating body 14 is screwed.

When the operating body 14 is not in the operating position, the switch piece 13 contacts the guide surface 29, so the switch piece 13
However, even with a planar structure in which the slits 37 are partially separated as illustrated, fatigue is less likely to occur and operation is easy.

When the container part 1 is connected to the lower part 3A of the main body and the setting is completed by raising the sliding shaft 16 to the setting surface 17c, marks M1 and M2 provided on the container part 1 and the lower part 3A of the main body, respectively. The positions of are the same. Also the operating body 1
4 and the upper portion 3B of the main body are also provided with marks M3, M4, and M5, respectively. The mark M4 on the main body side indicates an off position, and the mark M5 indicates an on position.

A battery 38, which is a power source, is housed in the upper portion 3B of the main body and is covered with an end cover 40 detachably attached to the upper end of the main body by an engaging means 39. In each drawing, 41 is a slide pipe integrally provided with the drive gear 34, and the slide pipe 41 engages with a guide protrusion 33a provided on the upper portion of the screw shaft 5 to secure the screw shaft 5 inside. It has a guide groove 33b for moving up and down. 42
Is a lower part of the gear frame, and 43 is an upper part of the gear frame, to which the above-mentioned gear set and the like are attached. Reference numeral 44 indicates a battery chamber, and 45 indicates a cup.

In the hand-held ice shaving device according to the present invention having the above-described structure, the switch 10 is turned on only after the container portion 1 is mounted on the main body 3 and the operating body 14 is operated. In other words, the stage where the container part 1 is just attached to the main body 3,
Alternatively, even if only the operation body 14 is operated, the switch is not turned on when the container 1 is not attached.

The switch piece 13 can be pushed while the two conditions of the mounting of the container portion 1 and the operation of the operating body 14 are satisfied, whereby the contact 12 in the fixed position comes to the set position. Since the contact 11 is contacted and the power supply circuit 9 is closed, the motor 8 rotates to drive the rotating body 4.

Therefore, if ice is contained in the container 1, the ice is rotated by the rotating body 4 and scraped by the cutter 2,
That is, the ice pieces fall below the slit 20 at a fixed position. While using it, there is no problem to keep holding the ice shaving device, pressing the switch piece 13 will scrape the ice, and releasing it will stop the operation. Can be applied.

[0023]

[Effects of the Invention] Since the present invention is configured and operates as described above, it can be used while being held in one hand and moved, and during operation, the operation and stop of the ice scraper can be arbitrarily controlled. Therefore, it is very convenient not only for making frozen desserts but also for cooking, for example, or for evenly distributing shaved ice over a large area when cooling with ice.
