Of the mahjong aids 1, 2 is a stacking tile in which only the specified N tiles (here, N = 17) are arranged in a row in the horizontal direction, and the tiles 20 are stacked vertically in two stages (Fig.). It is a frame body formed in a shape capable of surrounding the back surface and both left and right side surfaces in a U shape (see reference numeral 30 of 1), and is a horizontally long and prismatic back side frame portion 3 and a back side frame portion 3. It is composed of L-shaped projecting frame portions 4 and 5 provided at the left and right ends. 6 is rotatably mounted between the front horizontal direction and the upward vertical direction by a shaft support portion (see reference numerals 7 and 8 described later) provided near the front lower end of the projecting frame portions 4 and 5 of the frame body 2. It is a front surrounding portion made of a horizontally long and rectangular thin plate member capable of surrounding the front surface of the stacked tile 30. Hinge 7 and 8 as shaft support are mounted between the lower surface side of the lower end of the front side of the projecting frame portions 4 and 5 and the left and right ends of the lower portion of the front surrounding portion 6 which is the lower side when standing up. , The front surrounding portion 6 is rotatable between the front horizontal direction and the upward vertical direction.

The height H of the frame body 2 is formed so that d <H ≦ 3d (preferably 1.5d ≦ H ≦ 2.), where d is the height of the tile 20 lying downward (see FIG. 3 (1)). 5d, more preferably H = 2d). In FIG. 1, it is assumed that H is formed slightly higher than 2d. The width W of the inner space 9 of the frame body 2 is formed in N · w ≦ W (preferably N · w ≦ W), where the width W of the tile 20 lying downward is w (see FIG. 3 (1)). ≦ (N + 1) · w, more preferably W = (N + 0.5) · w). In FIG. 1, it is assumed that W is formed slightly longer than N ・ w. The depth D of the inner space 9 of the frame body 2 is formed so that h ≦ D <2h, where h is the height of the standing tile 20 (see FIG. 3 (2)) (preferably h ≦ D ≦ 1. 5h, more preferably D = 1.3 · h). In FIG. 1, it is assumed that D is formed slightly longer than h.

On the other hand, the width L of the front surrounding portion 6 is formed to have a length that reaches from the protruding frame portion 4 at the left end portion of the frame body 2 to the protruding frame portion 5 at the right end portion, and is abbreviated as the width width of the frame body 2 here. It is assumed that they are formed in the same way. Further, the front surrounding portion 6 is formed so that the height H1 of the upper end when standing vertically is 1.4 times or more the height d of the tile 20 lying down, and here, H 1 = 3d. It is assumed that it has been done. Further, the height H2 of the lower end of the front surrounding portion 6 is formed to be 0.8 times or less the height d of the prone tile, and here, it is assumed that the height H2 is about 0.2d (H2 = 0.2d). See Figure (3)).
Wood, plastic material, hard paper material, rubber material, or the like can be used as the material of the frame body 2 and the front surrounding portion 6 (the same material may be used for the frame body 2 and the front surrounding portion 6, and they are different. Material may be used).

Next, a method of using the above-described embodiment will be described with reference to FIGS. 5 to 10.
Before stacking tiles, place the mahjong aid 1 near the tabletop and tilt the front enclosure 6 in the front horizontal direction. The user collects a large number of tiles 20 on the table by hand, puts them in the inner space 9 of the frame 2 in a state of lying down one by one, and arranges them side by side (FIGS. 5 (1) to (3), FIG. 7 (FIGS. 5 (1) to (3)). 1)). When the first row is finished, another tile 20 is placed on the lower tile 20, and the second tile is also arranged side by side in the same manner (FIGS. 6 (1) to (3), FIG. 7 (2)). reference). The gap between the inner walls 10 to 12 of the inner space 9 and the tile 20 is narrow, and the inner walls 10 to 12 of the inner space 9 serve as a ruler and a support wall. Align to.
As shown in FIG. 8 (1), when the rows of tiles 20 stored in the internal space 9 are slightly disturbed, the frame 2 is moved diagonally forward and each tile 20 is pressed against the inner walls 10 to 12. It can be aligned in a straight line (see FIG. 8 (2)).

When N = 17 tiles on the side and two tiles on the top and bottom are completed, the front enclosure 6 is erected vertically upward to enclose the tiles 30 on all sides (arrows in FIG. 1, arrow in FIG. 7). (Refer to the arrow in (3)), the front enclosure 6 and the frame 2 are slid on the table together with the tiles 30 and pushed out to a predetermined position in front to move. When the front enclosure 6 is erected vertically upward and the stacked tiles 30 are pushed out to a predetermined position in front, and the front surface of the row of the stacked tiles 30 is slightly disturbed (see FIG. 9 (1)), the frame. By moving the body 2 diagonally backward and pressing each tile 20 against the back surface 13 and the inner walls 11 and 12 of the front surrounding portion 6, the tiles can be aligned in a straight line (see FIG. 9 (2)).
Then, when the mahjong auxiliary tool 1 is lifted upward and separated from the stacked tiles 30, the horizontal N = 17 tiles and the upper and lower two-tiered tiles 30 remain on the table, and the tiles are completed (FIG. 10). reference).

According to this embodiment, since the inner walls 10 to 12 of the inner space 9 of the frame 4 serve as a ruler and a support wall, the front surrounding portion 6 is horizontally tilted forward to open the front of the frame 2 and lie down. A large number of tiles 20 can be placed side by side in the inner space 9 of the frame 2 or stacked in two layers, and the specified number of tiles 20 can be arranged in a horizontal row and stacked in two layers. Further, by rotating the front enclosure 6 to stand upright vertically and sliding the tabletop together with the frame body 2 and the step stacking tile 30 and pushing it forward, the aligned step stacking tiles 30 are not collapsed. It is possible to move to the desired location on the table while surrounding it on all sides. Finally, when the mahjong auxiliary tool 1 is lifted upward and separated from the stacked tiles 30, the stacked tiles 30 remain on the table and the tiles are completed. As a result, even a user with poor finger movement can easily perform the stacking work.

In the above embodiment, the front enclosure has a horizontally long rectangular plate shape, but as shown in the front enclosure 6A of the mahjong auxiliary tool 1A in FIG. 11 (1), a horizontally long rectangular fence shape may be used. Of course, as shown in the front surrounding portion 6B of the mahjong auxiliary tool 1B of 11 (2), it may be replaced with various shapes such as a horizontally long rectangle having a plate shape with a large number of through holes 14.

Further, a fixing means for detachably fixing the front plate upright in the vertical direction upward to the left and right ends of the frame may be provided. For example, as shown in the mahjong auxiliary tool 1C of FIG. 12, the magnetically attached member 15 as an example of the fixing means at the front surfaces of the left and right projecting frame portions 4 and 5 of the frame body 2 and the corresponding portions of the front surrounding portion 6. If 16 is attached and the front surface of the upright front plate 6 and the front surfaces of the left and right projecting frame portions 4 and 5 are magnetized so as to be detachably attached, it takes time and effort to manually support the upright front surrounding portion 6. It can be omitted (when the magnetic member 15 on the front surface of the projecting frame portions 4 and 5 is used as a magnet, the magnetized member 16 of the front surrounding portion 6 may be a magnetic material such as a magnet or a steel plate, and the projecting frame portion 4 If the magnetic member 15 on the front surface of 5 is made of a magnetic material, the magnetic member 16 of the front surrounding portion 6 may be made of a magnet).
Further, although described as N = 17, the number may be other than 17, such as 16 and 18.

The present invention is suitable for a person with poor finger movement to enjoy mahjong at a sparrow cottage, an elderly home, a home, or the like.
