Abstract

[Problem] To provide a structure in which multiple parts are stacked vertically to drop a ball, where the unexpectedness of the ball's movement is appealing, and which can be realized with a simple structure. [Solution] The structure is a toy or ornament. Multiple parts are arranged in a vertical direction, and a ball falls from the upper part to the lower part. Each part has a hole that extends horizontally and widens from one end to the other, allowing the ball to move horizontally. The width of one end of the hole is shorter than the outer diameter of the ball, and there is a section between the two ends that is wider than the outer diameter of the ball, into which the ball falls. The widest width of the hole in each of the multiple parts is longer than the outer diameter of the ball. [Selection Diagram] Figure 2

Description

This invention relates to a structure for toys, ornaments, and the like. Conventional toys often consist of flat parts stacked vertically, with each part inclined downwards from one end to the other. A ball moves along guides formed on each part due to its weight. In this particular toy, holes are formed at predetermined locations on each part, allowing the ball to fall into the lower part.

The following describes a toy (structure) according to an embodiment of the present invention. The toy of this embodiment has a structure in which multiple parts are stacked vertically and in which a ball falls from the upper part to the lower part. Figure 1 is a perspective view of a toy 11 according to an embodiment of the present invention. Figure 2 is a perspective view of the toy 11 shown in Figure 1 with the ball in place. Figure 3 is a right side view of the toy 11 shown in Figure 1. As shown in Figures 1 and 2, the toy 11 has a structure in which multiple parts 21 to 25 are arranged from top to bottom so that they overlap. Each of the parts 21 to 25 has a horizontally extending hole 31 to 35 formed within it. The holes 31 to 35 have a width w that widens horizontally from one end to the other, and are formed so that when a ball 41 is placed in them, the ball 41 moves horizontally from one end to the other. In this embodiment, holes 31 to 35 are through holes. In this embodiment, one or more balls are used. Furthermore, when multiple balls are used, their outer diameters may be the same or different. The width of one end of holes 31-35 is shorter than the outer diameter of ball 41. Furthermore, the holes 31-35 have a width wider than the outer diameter of the ball 41 between one end 41-45 and the other end 51-55, where the ball may fall. The widest width of holes 31-35 is longer than the outer diameter of the ball. This structure allows the ball to fall through holes 31-35 in each part. In the vertical direction, the holes 31 of part 21 and 32 of part 22, which are adjacent to each other, have opposite directions of width w expansion in the horizontal direction. The holes 32 in part 22 and 33 in part 23 have opposite directions of width w expansion in the horizontal direction. The holes 33 in part 23 and 34 in part 24 have opposite directions of width w expansion in the horizontal direction. The holes 34 in part 24 and 35 in part 25 have opposite directions of width w expansion in the horizontal direction. This structure allows the ball to move in one direction on the upper part, then fall and move in the opposite direction on the lower part. Holes 31 to 35 are, for example, identical in shape. This structure allows a ball that falls from the upper part to the lower part to move horizontally along holes 31 to 35 at the same speed. The bottommost part 25 below part 24 should have a configuration that allows it to hold the ball within a predetermined range using predetermined holes or guides. Parts 21 to 25 are held by the holding member 81 at a predetermined interval in the vertical direction. Figure 4 is a plan view of part 21 of the toy 11 shown in Figure 1, and is a diagram used to explain the cross-sectional lines. Figure 5 is a cross-sectional view of part 21 along the cross-sectional line A-A shown in Figure 4. Figure 6 is a cross-sectional view of part 21 along the cross-sectional line B-B shown in Figure 4. Figure 7 is a diagram illustrating the planar structure of the parts of the toy 11 shown in Figure 1. The cross-section of the part 21 shown in Figures 4 and 5, in a direction perpendicular to the direction in which the ball in the hole 31 moves, consists of a first opening 61 formed on the upper surface of the part 21, a second opening 62 formed on the lower surface of the part 21, and an inclined portion 63 located between the first opening 61 and the second opening 62. The opening diameter w2 of the second opening 62 is shorter than the opening diameter w1 of the first opening 61. The width of the hole 31 is the opening diameter w2 of the second op
