  With reference to FIGS. 1-12, the structure of the drink stirring apparatus 10 (henceforth "stirring apparatus") which converts the descent | fall movement by gravity into rotational force by seven desirable embodiment of this invention is demonstrated in detail. .

  First, with reference to FIG. 1 thru | or FIG. 4, the basic structure of the stirring apparatus 10 by 1st Embodiment of this invention is demonstrated.

  The stirring device 10 includes a main body 20, a rotating arm 30, a tray 40, a rotating disk 45, a power transmission unit, and a horizontal maintaining unit.

  The main body 20 is a basic frame constituting the stirring device 10. The main body 20 can be formed by molding a metal material or a synthetic resin, for example. The main body 20 has a structure supported on the ground. The body 20 is provided with a guide gear 27. In the present embodiment, as shown in FIG. 1, the guide gear 27 may be configured in the form of a circular gear centered coaxially with a first reference shaft 35 to be described later. The guide gear 27 may be provided so as to be fixed to the main body 20 when the tray 40 described later is lowered, and to be rotated with respect to the main body 20 when the tray 40 is raised. . In such a configuration, when the tray 40 is raised, the guide gear 27 rotates when the rotating arm 30 described later rotates. Such a function is realized by connecting the guide gear 27 and the main body 20 via a ratchet wheel or a one-way clutch bearing.

  The rotary arm 30 is a rod-shaped structure. The rotating arm 30 is rotatably coupled to the main body 20. More specifically, the rotary arm 30 is provided to be rotatable with respect to the main body 20 with respect to a first reference shaft 35 parallel to the ground. The rotary arm 30 is provided with one end longer than the other end with respect to the first reference shaft 35.

  The tray 40 is disposed at one end in the longitudinal direction of the rotary arm 30. The tray 40 is rotatably coupled to the rotary arm 30 with reference to a second reference shaft 42 disposed in parallel with the first reference shaft 35. The upper surface of the tray 40 is configured in a flat shape. In the center of the tray 40, there is a hole penetrating the upper surface and the lower surface. The hole is provided with a turntable 45 described later.

  The turntable 45 is rotatably coupled to the upper surface of the tray 40. More specifically, the turntable 45 is provided in a hole provided in the tray 40. The tray 40 is rotatably provided with reference to a third reference shaft 47 arranged in a direction perpendicular to the upper surface of the tray 40. A container for storing a drink such as a paper cup is placed on the upper surface of the rotating plate 45.

  The power transmission unit is a power transmission device that converts the rotational force of the rotary arm 30 into the rotational force of the rotating disk 45 when the rotary arm 30 rotates with respect to the first reference shaft 35. The power transmission unit may include a plurality of pulleys and a belt. Meanwhile, the power transmission unit may include a power transmission gear set 59. The specific structure of the power transmission unit will be described in detail below.

  The horizontal maintaining unit is a power unit that performs an operation of maintaining the upper surface of the rotating disk 45 in parallel with the ground. The horizontal maintaining unit rotates in the direction opposite to the rotating direction of the rotating arm 30 so that the upper surface of the rotating disk 45 is always kept parallel to the ground.

  Now, the structure of the power transmission unit will be described in more detail.

  As shown in FIGS. 1 to 4, the power transmission unit may include a power transmission gear set 59, a first rotating body 54, a second rotating body 55, and a belt 57.

  The power transmission gear set 59 is rotatably provided on the rotary arm 30. The power transmission gear set 59 is configured by meshing a plurality of gears. The rotating shaft of the power transmission gear set 59 is disposed in parallel with the first reference shaft 35. The power transmission gear set 59 meshes with the guide gear 27. The power transmission gear set 59 is dependently rotated by the rotation of the rotary arm 30. The power transmission gear set 59 serves to increase the number of rotations so that the number of rotations of the second rotating body 55 described later is further increased than the amount of rotation of the rotary arm 30.

  The first rotating body 54 is connected to an output portion of the power transmission gear set 59. The first rotating body 54 is dependently rotated by the rotation of the power transmission gear set 59. More specifically, the first rotating body 54 is rotatably provided on the rotating arm 30. The first rotating body 54 rotates integrally with the rotating arm 30 around the first reference shaft 35. The rotation axis of the first rotating body 54 is disposed in parallel with the first reference axis 35. In the present embodiment, the first rotating body 54 is accelerated by the power transmission gear set 59 so as to have a larger rotation amount than the rotation amount of the rotary arm 30.

  The second rotating body 55 is provided on the second reference shaft 42. The second rotating body 55 is rotatably provided on the second reference shaft 42.

  The belt 57 is a member that connects the first rotating body 54 and the second rotating body 55. The second rotating body 55 is dependently rotated by the rotation of the first rotating body 54.

  The second rotating body 55 is connected to the rotating disk 45 that rotates with the third reference shaft 47 as a reference, for example, a pair of spokes 48 or a pair of bevel gears (not shown). Accordingly, when the second rotating body 55 rotates, the rotating disk 45 rotates around the third reference shaft 47. As a result, the paper cup 500 placed on the rotating plate 45 rotates around the third reference shaft 47.

  Meanwhile, the horizontal maintaining part includes a link member 62.

  The link member 62 extends from the tray 40. The link member 62 is fixed to the tray 40 or formed by a structure integrated with the tray 40. The link member 62 is provided so as to rotate about the second reference shaft 42. Accordingly, when the link member 62 is rotated, the tray 40 and the rotating disk 45 are integrally rotated with respect to the second reference shaft 42. Accordingly, the link member 62 is provided to rotate the tray 40 about the second reference shaft 42 in the direction opposite to the rotation direction of the rotation arm 30 by the rotation of the rotation arm 30. For example, the lower end of the link member 62 is provided to be connected to the main body 20 by a bar-like structure 63. Therefore, when the rotary arm 30 rotates, the link member 62 rotates the tray 40 about the second reference shaft 42 in the opposite direction to the rotation direction of the rotary arm 30 by the same angle. Can be configured. Thereby, the upper surface of the tray 40 is always maintained at a constant angle with the ground. More specifically, in the present invention, the upper surface of the tray 40 is maintained in parallel with the ground by the horizontal maintaining unit.

  A restoring weight 90 is provided at the other end of the rotating arm 30.

  The restoring weight 90 is disposed on the opposite side of the tray 40 with respect to the first reference shaft 35. The restoration weight 90 is provided to position the tray 40 at the top dead center in a state where a heavy object such as the paper cup 500 is not placed on the upper surface of the tray 40. That is, due to the weight of the restoring weight 90, the rotating arm 30 rotates clockwise about the first reference shaft 35, and the tray 40 is located at the top dead center.

  The operation and effect of the stirrer 10 according to the first embodiment having the above-described components will be described by taking as an example a case where coffee is mixed into the paper cup 500.

  First, the paper cup 500 is charged with coffee, cream and sugar. Then, hot water is poured into the paper cup 500. Now, the paper cup 500 is placed on the rotating plate 45 disposed on the upper surface of the tray 40. Due to the weight of the paper cup 500 applied to the tray 40, the rotary arm 30 rotates counterclockwise about the first reference shaft 35. As a result, the tray 40 moves to a position lower than the initial position. In this process, the horizontal maintaining unit always maintains the upper surface of the tray 40 in a state parallel to the ground surface by rotating the tray 40 in a direction opposite to the rotation angle of the rotating arm 30. Accordingly, coffee or hot water charged in the paper cup 500 placed on the upper surface of the tray 40 is not discharged outside the paper cup 500. Further, when the rotary arm 30 is rotated with respect to the first reference shaft 35, the power transmission gear set 59 meshed with the guide gear 27 is rotated. And the second rotating body 55 rotate. As the second rotating body 55 rotates, the rotating disk 45 rotates around the third reference shaft 47. As a result, the paper cup 500 placed on the upper surface of the rotating disk 45 rotates. As a result, the coffee, hot water, sugar and cream charged in the paper cup 500 are preferably mixed by rotation. If the coffee charged in the paper cup 500 is mixed with hot water, the user can take the coffee with the paper cup 500 by hand.

  As described above, the stirring device 10 according to the present invention can easily mix coffee without using a separate spoon by rotating the rotary arm 30 while the paper cup 500 rotates while maintaining the level. Provides the effect of being able to be taken. Further, the stirring device 10 has a simple structure and does not require a separate power source such as electricity, so that it is very economical.
