In this case, the second case 41 may be firmly coupled to the first case 40 to not relatively move with respect to the first case 40.
As illustrated in
The first case 40 may constitute an upper portion of the cup holding assembly 30, and the second case 41 may constitute a lower portion of the cup holding assembly 30, but the present invention is not limited thereto.
In this specification, an example in which the cup holding assembly 30 according to one embodiment of the present invention includes the plurality of four holding modules 35a, 35b, 35c, and 35d is mainly described, but the number of the plurality of holding modules is not necessarily limited thereto.
In this case, when the number of the plurality of holding modules is changed, the number of the plurality of accommodation portions may also be changed correspondingly.
For example, the cup holding assembly 30 according to one embodiment of the present invention may also include a plurality of holding modules and the plurality of accommodation portions of which the numbers are the same.
The plurality of holding modules 35a, 35b, 35c, and 35d serve to hold a cup by coming into direct contact with the cup.

That is, the plurality of holding modules 35a, 35b, 35c, and 35d may include the seating parts 34 (see
A first inner opening BB overlapping the holding space AA is formed in the rotary plate 42, and the rotary plate 42 includes at least one spiral rail 44 which is non-fixedly coupled to the plurality of seating parts 34 (see
The rotary plate 42 may include the at least one spiral rail 44 to provide a spiral guide path to the plurality of seating parts 34.
In the present specification, a case in which the rotary plate 42 includes one spiral rail 44 will be described. However, the rotary plate 42 may also have a plurality of spiral rails 44.
A curvature of the spiral rail 44 may decrease away from the holding space AA and the first inner opening BB.
For example, referring to
Meanwhile, a structure in which the plurality of holding modules 35a, 35b, 35c, and 35d are seated on the spiral rail 44 by the seating parts 34 may vary.
Each of the seating parts 34 formed on one of the plurality of holding modules 35a, 35b, 35c, and 35d may have a shape protruding outward from the holding module. In this case, the spiral rail 44 may be formed to be recessed to accommodate the protruding shape of the seating part 34 (see
The seating part 34 may have any protruding shape.
For example, the seating part 34 may be formed in a cylindrical shape or arc shape to protrude outward from the holding module.
For example, referring to
In this case, the seating parts 34 formed in the plurality of holding modules 35a, 35b, 35c, and 35d are seated on the spiral rail 44 in a manner of being non-fixedly coupled to the spiral rail 44.
In addition, for example, the seating part 34 formed in each of the plurality of holding modules 35a, 35b, 35c, and 35d may have a recessed shape in the holding module. In this case, the spiral rail 44 may be formed in a protruding shape to be engaged with the recessed shape of the seating part 34 (not illustrated).
As described above, since the seating part 34 formed on each of the plurality of holding modules 35a, 35b, 35c, and 35d and the spiral rail 44 are mutually engaged, the plurality of holding modules 35a, 35b, 35c, and 35d can be seated on the rotary plate 42.
In this case, the mutually engaging structure of the seating part 34 and the spiral rail 44 should be formed so that the seating part 34 is movable on the spiral rail 44.
That is, as illustrated in
Meanwhile, since the plurality of seating parts 34 are formed on the plurality of holding modules 35a, 35b, 35c, and 35d, it may also be described that the spiral rail 44 provides the spiral guide path to the plurality of holding modules 35a, 35b, 35c, 35d).
Meanwhile, as illustrated in
When the rotary plate 42 relatively moves or rotates with respect to the plurality of holding modules 35a, 35b, 35c, and 35d, the plurality of seating parts 34 move along the spiral rail 44, and thus the plurality of holding modules 35a, 35b, 35c, and 35d may move along the spiral rail 44.
In this case, as the plurality of seating parts 34 move along the spiral rail 44, the plurality of holding modules 35a, 35b, 35c, and 35d straightly move within the plurality of first accommodation portions 32a, 32b, 32c, 32d.
Accordingly, as the plurality of seating parts 34 move along the spiral rail 44, the plurality of holding modules 35a, 35b, 35c, and 35d may move toward or away form a center of the holding space AA or the first inner opening BB.
An example in which the plurality of holding modules 35a, 35b, 35c, and 35d straightly move within the plurality of first accommodation portions 32a, 32b, 32c, and 32d to move toward or away from the center of the holding space AA or the first inner opening BB is illustrated in
