[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an ice scraper, and the present invention relates to a rotation drive unit that rotates ice stored in an ice storage unit while pressing it against an ice scraper blade. It is equipped with a rotary shaft body formed with independent endless teeth at predetermined pitches along the axial direction and provided with an ice holding part at the tip, and a gear mechanism that meshes with the rotary shaft body to provide linear motion in the axial direction. With this structure, by simply rotating the rotary shaft using a handle or the like, rotation and pressing force necessary for ice scraping can be obtained.

<Conventional technology> In a conventional ice scraper, an ice scraper is fixedly attached to the bottom of the ice storage unit, and a rotary drive unit is detachably attached to the top side of the ice storage unit, and the ice scraper is stored in the ice storage unit. The structure is such that the ice is scraped by rotating the ice while pressing it against the ice scraper blade using the rotary drive mechanism. A common method for pressing ice against an ice scraper is to apply pressing force directly with a handle.

<Problems to be Solved by the Invention> However, this conventional ice scraper uses a method of directly applying pressing force using the handle to press the ice against the ice scraper blade while rotating the ice. It required a lot of effort to shovel the ice, making it unsuitable for children with weak physical strength.

<Means for Solving the Problems> In order to solve the above-mentioned conventional problems, the present invention provides an ice storage section having an ice scraper blade, and a method for storing ice stored in the ice storage section using the ice scraper blade. The ice scraper includes a rotation drive unit that rotates while pressing the ice scraper, the rotation drive unit including a handle, a rotation shaft body,
a gear mechanism, the handle has a shaft portion and a handle portion, the shaft portion has a shaft hole opening at a lower end side, and the handle portion is attached to an upper side of the shaft portion. The rotary shaft body has endless teeth and an ice holding portion, and the endless teeth are endless around the outer peripheral surface of the shaft and are arranged in large numbers independently at predetermined pitches along the axial direction. the ice presser is attached to the tip end, and the rear end side is inserted into the shaft hole of the handle and coupled to the handle so that it can rotate and slide in the axial direction at the same time, the gear mechanism, It has a first gear, a second gear, and a third gear, the first gear is provided on the outer peripheral surface of the shaft portion of the handle, and the second gear and the third gear are disposed on the side of the rotating shaft body and are coupled so as to be rotatable at the same time, the second gear meshes with the first gear, and the third gear meshes with the endless teeth and connects the second gear. It is characterized in that linear motion in the axial direction is imparted to the rotary shaft body by the rotational force transmitted from the gear.

<Function> The rotating shaft body constituting the rotational drive unit has a large number of endless teeth arranged around the outer circumferential surface of the shaft and independently at predetermined pitches along the axial direction, and the ice holding part is located at the tip. The gear mechanism has a first gear provided on the outer peripheral surface of the shaft of the handle, a second gear and a second gear. A third gear is coupled to rotate simultaneously, the second gear meshes with the first gear, and the third gear meshes with the endless tooth and rotates by the rotational force transmitted from the second gear. Since linear motion in the axial direction is applied to the shaft, when the rotating shaft is rotated by the handle, a rotational force is applied to the ice from the ice press provided at the tip of the rotating shaft. Simultaneously with this rotational movement, linear movement in the axial direction is applied to the rotating shaft from the gear mechanism, and at the same time the ice stored in the ice storage section is pressed against the ice scraper blade by the rotational drive section. , is rotated and ice is scraped.

Furthermore, by simply rotating the rotating shaft with the handle, linear motion to obtain the rotation and pressing force necessary for ice scraping can be simultaneously ensured by one rotating shaft, and the number of parts is small and the structure is simple. You can get a nice ice shaver.

The handle has a shaft hole in which the shaft portion opens at the lower end side, and the rotating shaft body is coupled such that the rear end side thereof is inserted into the shaft hole of the handle, rotates at the same time as the handle, and slides in the axial direction. Therefore, the linear momentum of the rotary shaft body can be absorbed within the shaft hole of the handle, and no movement disorder occurs.

In the gear mechanism, the first gear is provided on either the shaft of the handle or the outer peripheral surface of the rotating shaft, and the second gear and the third gear are arranged on the side of the rotating shaft and rotate at the same time. Since the three gears are connected to give linear motion to the rotating shaft,

Then, the protrusion 203 enters the groove 10c, and the latching mechanism 9 is moved by the inclined surface a of the protrusion 10e.
The back surface b of the rotating piece 91 constituting the is pressed, and the rotating piece 91 rotates about the rotating shaft 92. Therefore, the hook-shaped end 91a of the rotating piece 91 comes off from the bottom plate 3, resulting in the state shown in FIG. 3, and the bottom plate 3 is released from the restraint by the latching mechanism 9.

The rotation drive mechanism 11 is configured such that by rotating the handle 113, the rotating shaft body 111 can be rotated and fed in the axial direction. A shaft hole 114b with a key groove 114a is formed inside the shaft portion 114 of the handle 113, and a first shaft hole 114b is formed on the outer periphery of the end, as shown in FIG.
A rotating shaft body 111 having a key portion 111a protruding from its head is fitted into the shaft hole 114b. On the outer periphery of the rotating shaft body 111, independent endless teeth 111b are formed at predetermined pitches along the axial direction.

The gear mechanism 112 includes a first gear 114c and a second gear 1 that meshes with the first gear 114c.

Adjustment arm 11 rotatably pivoted in space 10a of
The shaft is fixed at 2d.

When the handle 113 is rotated, the rotating shaft body 111
rotates simultaneously with the handle 113. A first gear 114c is formed on the shaft portion 114 of the handle 113, and a second gear 112a is meshed with the first gear 114c.
13, the third gear 112b rotates together with the second gear 112a. Third gear 11
2b meshes with endless teeth 111b formed on the outer peripheral surface of the rotating shaft 111, so as the third gear 112b rotates, linear movement in the axial direction _Z1 with respect to the rotating shaft 111 occurs. Given. Therefore, the rotating shaft body 111 rotates simultaneously with the rotation movement by the handle 113, and simultaneously rotates the third gear 112b and the endless tooth 111b.
A linear motion is given by the meshing with the

As the handle 113 rotates, the rotating shaft 111 also rotates, so the endless teeth 111b of the rotating shaft 111 rotate and mesh with the third gear 112b. 112b. In other words,
The axial rotation of the rotary shaft body 111 is absorbed by the slippage generated between the rotary shaft body 111 and the third gear 112b, and is not transmitted to the third gear 112b.

Moreover, the rotation shaft body 111 can be rotated by the handle 113.
Just by rotating the shaft, one rotating shaft body 1 can perform linear motion to obtain the rotation and pressing force necessary for ice scraping.
11 at the same time, an ice scraper with a small number of parts and a simple structure can be obtained.

The handle 113 has a shaft hole 114b that opens at the lower end of the shaft, and the rear end of the rotating shaft 111 is inserted into the shaft hole 114b of the handle 113, rotates at the same time as the handle 113, and slides in the axial direction. Since the rotary shaft body 11 is coupled so as to obtain
The linear momentum of 1 is the shaft hole 114b of the handle 113.
It can be absorbed within the body and does not cause movement disorders.

In the gear mechanism, the first gear 114c is connected to the handle 1.
The second gear 112a and the third
Since the gear 112b is arranged on the side of the rotating shaft body 111 and is coupled so as to be able to rotate at the same time,
It has a structure in which three gears that give linear motion to the rotating shaft body 111 are aligned in the axial direction of the rotating shaft body 111, and the rotational force of the handle 113 is reliably transmitted to the rotating shaft body 111 with a simple structure. Can perform linear motion.

A structure in which 112A to 112C are provided and these are selectively engaged with the gears of the rotating shaft 111 and the handle 113 is effective. With such a structure, the rotation of the handle 113, the rotating shaft body 111, and the ice holding part 12 and the amount of feed thereof can be adjusted.

Further, the ice storage section B is formed by integrally forming a cylindrical inner box 1 and an outer box 2 in a coaxial and cylindrical shape using a suitable plastic material. The inner box 1 has an ice storage chamber 101 therein, a bottom plate 3 disposed at the bottom of the ice storage chamber 101, and an open top side opposite to the bottom plate 3.

As shown in FIG. 6, the bottom plate 3 has an ice cutting hole 31 extending from the center in the diametrical direction with an appropriate width, and has protrusions 32 formed at intervals at several locations on the outer periphery. It is located within a notch 103 provided in the cylindrical portion 102 of the inner box 1. Further, a spring 4 is interposed between the outer surface of the bottom plate 3 and the bottom surface 201 of the outer box 2 to bias the bottom plate 3 upward in the figure.

The outer box 2 has an ice outlet 202 formed on a bottom surface 201 facing the bottom plate 3, which overlaps with the ice cutting 31 of the bottom plate 3, and an ice scraper blade 5 is attached and fixed along the ice outlet 202. Blade tip 5 of ice scraper blade 5
1 is located below the ice cutting hole 31. 6
is a screw that fixes the ice scraper blade 5 to the bottom surface 201 of the outer box 2.

In the annular space 8 between the outer circumferential surface of the inner box 1 and the inner circumferential surface of the outer box 2, there is a rotation drive section A for the ice storage section B.
A latching mechanism 9 is formed that latches the bottom plate 3 to the bottom of the inner box 1 and releases the latching state as the bottom plate 3 is attached and detached. The latching mechanism 9 rotatably locks the intermediate portion of the rotary piece 91 to the cylindrical portion of the outer box 2 with a shaft 92, and a plate spring is provided between the back surface of the rotary piece 91 and the inner surface of the outer case 2. It has a structure arranged as 93. The tip 91a of the rotating piece 91 is hook-shaped.

In the state shown in FIG. 1 in which the rotational drive unit A is not connected to the ice storage unit B, the inner box 1 constituting the ice storage unit B is
The bottom plate 3 placed on the bottom of the outer box 2
1 and is biased by a spring 4 interposed between the
The ice scraper blade 5, which is raised from the bottom surface 201 of the outer box 2 and arranged on the bottom surface 201 of the outer box 2, leaves the ice cutting hole 31 provided in the bottom plate 3. At the same time, the hook-shaped tip 91a of the latching mechanism 9 provided between the inner box 1 and the outer box 2 causes the bottom plate 3 to be attached to the inner box 1.
can be hung on the bottom of the

Therefore, the cutting edge 51 of the ice scraper 5 attached to the bottom of the outer box 2 is fixed at a position away from the bottom plate 3 provided at the bottom of the inner box 1, and the bottom plate Even if you press 3, the bottom plate 3 remains in the same position. Therefore, even if you put your fingers inside the inner box 1 during cleaning or the like, your fingers will not come into contact with the ice scraper blade 5, making it safe.

When ice is placed inside the inner box 1 and the ice storage section B and rotation drive section A are assembled as shown in FIG. 2, the restraint of the bottom plate 3 by the latching mechanism 9 is released. In the state shown in FIG. 2, the bottom plate 3 is pressed upward in the figure by the spring pressure of the spring 4.

Next, when the handle 113 is rotated, the rotating shaft 111 and the ice pressing plate 12 fixedly attached to the tip thereof are rotated and fed by the rotational feeding action described above. Therefore, the ice 13 between the bottom plate 3 and the ice holding plate 12 is rotated and fed, and the bottom plate 3 moves downward against the spring 4. As a result, the ice scraping blade hits the lower surface of the ice 13 through the ice cutting hole 31 provided in the bottom plate 3, and the surface of the ice 13 is scraped off. Thereafter, the ice 13 is scraped off by an amount corresponding to the feed amount until the ice 13 is removed. After ice scraping is completed, the gear mechanism 112 is disengaged from the rotating shaft body 111 and returned to its original state.
