Description

  The present invention relates to a playground equipment.

  There are wooden and plastic playground equipment for babies to play. A wooden playground equipment is considered to be more preferable in terms of touch, texture and the like than a plastic playground equipment. Also, wooden playground equipment is unlikely to crack due to deterioration over time unlike plastic ones, so that it can be used for a long time if it is made properly. However, it is difficult to form wood in a free shape with a mold such as plastic.

  Therefore, conventional wooden play equipment is limited to building blocks as in Patent Document 1, simple movements that infants play by shaking, pushing, and pulling by hand, and those that play with a tonker. It has been. Further, the conventional wooden playground equipment is limited to riding equipment such as a wooden horse or a car that an infant can ride and play.

JP 2004-16700 A (abstract, claims, detailed description of the invention, etc.)

  However, the conventional play equipment found in the building blocks described in Patent Document 1 has a simple movement, and it is difficult for an infant or the like to play with the play equipment over a long period of time. Even if the play equipment is not made of wood, such as plastic play equipment, the same problem occurs when the play equipment moves simply.

  In addition, there are many conventional playground equipments that are moving, such as trains, and many of them require a large plane space.

  The present invention has been made in view of the above problems, and provides a playground equipment that allows an infant or the like to play with the playground equipment for a longer period of time than a conventional wooden playground equipment and does not require a lot of plane space. The purpose is to do.

  A second playground equipment according to the present invention includes a sphere, a playground table, a front cover plate erected on the playground table, and spaced apart from the front cover plate on the playground table by a distance larger than the size of the sphere. A rear cover plate that is erected, a rotating body that is disposed between the front cover plate and the rear cover plate and that is rotatably supported by the front cover plate and the rear cover plate, and a handle that rotates the rotary body An arm, a transport hole that is formed as a hole in the outer peripheral portion of the rotating body and accommodates the sphere, a sphere discharge hole that is opened at a position above the back cover plate and overlaps the transport hole, and the front surface A sphere suction hole is provided at a position below the sphere discharge hole and below the sphere discharge hole so as to overlap with the transport hole, and a circulation path through which the sphere rolls from the sphere discharge hole to the sphere suction hole.

  By adopting this configuration, by rotating the handle arm, the sphere in the sphere suction hole is accommodated in the transport hole of the rotator and lifted while being supported by the front cover plate and the back cover plate so as not to fall down, It is discharged from the ball discharge hole, rolls around the circulation path, and moves again to the wooden ball suction hole. As the handle arm continues to rotate, the sphere continues to circulate. Therefore, by this movement of the moving body, an infant or the like can play with the play equipment for a longer period of time compared to the conventional wooden play equipment. Further, since the sphere moves vertically, it does not require a lot of plane space as a playground equipment.

  In the present invention, by giving movement to the playground equipment, it is possible for an infant or the like to play with the playground equipment for a longer period of time compared to the conventional wooden playground equipment, and to take up a lot of plane space by incorporating vertical movement. It can be a playground equipment that is not required.

  Hereinafter, playground equipment concerning an embodiment of the invention is explained based on a drawing.

In the description of the playground equipment according to the first embodiment of the present invention based on the posture of the playground equipment body 2 in the front view of FIG.

  The playground equipment body 2 has a playground equipment stand 11. The playground equipment 11 is formed by forming a single piece of wood such as a beech material into a rectangular shape. The thickness of the playground equipment 11 is 1 to 3 cm.

  As shown in FIG. 3, a rail base 12, a front cover plate 13, a reinforcing fixing member 14, and a back cover plate 15 are disposed on the play equipment 11 in order from the front side of the play equipment. Further, as shown in FIG. 1, a right side cover member 16 is disposed on the right side of the back cover plate 15, and a left side cover member 17 is disposed on the left side of the back cover plate 15.

  The rail base 12 has a substantially rectangular parallelepiped shape. The rail base 12 is disposed in front of the right half of the front cover plate 13 in a posture in which the longitudinal direction thereof, that is, the horizontal direction in FIG. The upper surface of the rail base 12 in the arrangement state is lowered from the right to the left. A wooden ball 1 is placed on a later-described sixth rail member 51 disposed on the rail base 12.

  The front cover plate 13 is formed by forming a plywood having a thickness of less than 1 cm into a shape similar to a tongue. Plywood is strong in itself and is harder to bend and warp than a single piece of wood. The front cover plate 13 is erected on the playground table 11 such that the end face of the tongue-shaped base side is in contact with the playground equipment table 11 and the back surface is in contact with the reinforcing fixing member 14. The front cover plate 13 is erected in front of the reinforcing fixing member 14. The front cover plate 13 is screwed to the playground equipment 11 and the reinforcing fixing member 14 using wood screws.

  The front cover plate 13 erected on the playground table 11 is formed with constricted portions 13a and 13a on the left and right of the central portion in the vertical direction. By forming the constricted portions 13a, 13a, the upper portion of the front cover plate 13 has a substantially circular outer shape when viewed from the front, and confirms the wooden ball 1 moving upward as described later. it can. In the upper part of the front cover plate 13, four design holes 13b penetrating the front cover plate 13 are opened.

  The reinforcing fixing member 14 is made of wood in a substantially rectangular shape. The reinforcing fixing member 14 is screwed to the longitudinal direction of the playground equipment base 11, that is, the direction along the left-right direction in FIG. The reinforcing fixing member 14 has a depth slightly larger than the diameter of the wooden ball 1 in the front-rear direction in a state where the reinforcing fixing member 14 is disposed on the playground equipment 11.

  The back cover plate 15 is formed by forming a plywood having a thickness of less than 1 cm into a substantially rectangular shape. The back cover plate 15 has a size about two times larger than the front cover plate 13. The back cover plate 15 is erected on the playground equipment 11 such that the lower end of the back cover plate 15 is in contact with the playground equipment 11 and the front surface is in contact with the reinforcing fixing member 14. The back cover plate 15 is screwed to the playground equipment 11 and the reinforcing fixing member 14 using wood screws so as to stand behind the reinforcing fixing member 14. An interval between the back cover plate 15 and the front cover plate 13 is an interval corresponding to the width in the front-rear direction of the reinforcing fixing member 14, that is, an interval slightly wider than the diameter of the wooden ball 1.

  In the upper part of the back cover plate 15, a rectangular handle hole 19 penetrating the back cover plate 15 is opened. The handle hole 19 is large enough to accommodate several adult fingers. The play equipment body 2 can be lifted and transported in a well-balanced manner by having the handle hole 19 by hand. Further, the front cover plate 13 and the back cover plate 15 are screwed so as to stand on the playground table 11 and are screwed to the reinforcing fixing member 14. Therefore, when the handle hole 19 is held by hand, the distance between the back cover plate 15 and the front cover plate 13 is difficult to increase. Further, even if the playground equipment body 2 is lifted by holding only the handle hole 19, the playground equipment body 2 is not broken.

  The right side cover member 16 and the left side cover member 17 are wooden plates having a substantially rectangular shape. Grooves 16a and 17a are formed on one surface of these plate materials. The right side cover member 16 and the left side cover member 17 are erected on both left and right ends of the playground equipment 11 so that the groove portions 16a and 17a face each other.

  Further, the play equipment main body 2 includes a drive shaft 21 disposed on the lower left side in FIG. 1, a handle member 22 attached to the drive shaft 21, a driven shaft 23 disposed substantially in the center of the front surface, and a driven shaft 23. And a rotating body 24 that rotates together with the rotating body 24. The front cover plate 13 is provided with a drive shaft hole 25 and a driven shaft hole 26 corresponding to them. The rear cover plate 15 is also provided with a drive shaft hole 27 and a driven shaft hole 28.

  The drive shaft hole 25 of the front cover plate 13 is opened at a position below the front cover plate 13 and closer to the left end of the front cover plate 13. The drive shaft hole 27 of the back cover plate 15 is established at a position aligned with the drive shaft hole 25 of the front cover plate 13 fixed to the playground equipment 11. The drive shaft holes 25 and 27 have circular shapes that are slightly larger than the respective insertion portions of the drive shaft 21 so that the drive shaft 21 is inserted with play.

  The driven shaft hole 26 of the front cover plate 13 is opened at the center of the circular shape in the upper part of the front cover plate 13. The driven shaft hole 28 of the back cover plate 15 is opened at a position aligned with the driven shaft hole 26 of the front cover plate 13 fixed to the playground equipment 11. Both the driven shaft holes 26 and 28 have a long hole shape that is long in the vertical direction.

  The drive shaft 21 includes a large-diameter cylindrical portion 21a having a cylindrical shape with a substantially uniform radius, a small-diameter first protruding portion 21b protruding from the rear surface of the large-diameter cylindrical portion 21a, and a front of the large-diameter cylindrical portion 21a. It has the 1st protrusion part 21b which protrudes from the direction, and the 2nd protrusion part 21c of the same diameter. The large-diameter cylindrical portion 21a, the first protruding portion 21b, and the second protruding portion 21c are concentric. The outer diameter of the large-diameter cylindrical portion 21 a is larger than the inner diameters of the drive shaft hole 27 of the back cover plate 15 and the drive shaft hole 25 of the front cover plate 13.

  The first protrusion 21 b is inserted into the drive shaft hole 27 of the back cover plate 15. The second protrusion 21 c is inserted into the drive shaft hole 25 of the front cover plate 13. The second protrusion 21 c protrudes forward of the front cover plate 13. The drive shaft 21 is rotatably supported by the front cover plate 13 and the back cover plate 15.

  The handle member 22 includes a handle arm 22a having a substantially rectangular parallelepiped shape with a length of 4 to 8 cm, and a knob member 22b. One end of the handle arm 22a is fixed to a second projecting portion 21c of the drive shaft 21 that projects forward from the front cover plate 13. A wooden spacer 29 is disposed between the handle arm 22 a and the front cover plate 13. A knob member 22b is rotatably attached to the other end of the handle arm 22a.

  The driven shaft 23 has a cylindrical shape. One end of the driven shaft 23 is inserted into the driven shaft hole 28 of the back cover plate 15, and the other end is inserted into the driven shaft hole 26 of the front cover plate 13. The driven shaft 23 is rotatably supported by the front cover plate 13 and the back cover plate 15. Further, the driven shaft 23 can be moved in the vertical direction in the driven shaft holes 26 and 28 because the driven shaft holes 26 and 28 are elongated holes in the vertical direction. The other end portion of the driven shaft 23 projects forward from the front cover plate 13, and a hemispherical shaft cover member 30 is fixed to the other end portion.

  The rotating body 24 is formed by forming a plywood having a thickness of less than 1 cm into a disk shape having a substantially uniform radius. The outer peripheral surface of the rotating body 24 is flat with respect to the axial direction, like the outer peripheral surface of the cylinder. A driven shaft 23 is fixed at the center of the rotating body 24. As shown in FIG. 3, both ends of the driven shaft 23 protrude from the front surface and the back surface of the rotating body 24.

  FIG. 4 is an explanatory view showing a support state of the rotating body 24. As shown in FIG. 4, the driven shaft 23 can move in the vertical direction within the driven shaft holes 26 and 28. On the other hand, the distance between the driven shaft holes 26 and 28 and the drive shaft holes 25 and 27 is the same as or slightly shorter than the sum of the radius of the large-diameter cylindrical portion 21a of the drive shaft 21 and the radius of the rotating body 24. . Therefore, in a state where the drive shaft 21 and the driven shaft 23 are supported by the front cover plate 13 and the back cover plate 15, the outer peripheral surface of the rotating body 24 is arranged on the peripheral surface of the large-diameter cylindrical portion 21 a of the driving shaft 21. It abuts with a predetermined pressure due to the action of gravity. In this contact state, the driven shaft 23 is separated from the lower ends of the driven shaft holes 26 and 28, while the rotating body 24 and the driven shaft 23 ride on the drive shaft 21. The weight of the wooden rotating body 24 and the driven shaft 23 is added to the drive shaft 21. For example, when the drive shaft 21 is rotated, the frictional force acting between the outer peripheral surface of the rotating body 24 and the peripheral surface of the large-diameter cylindrical portion 21a of the drive shaft 21 is increased by their weight. Therefore, the rotating body 24 rotates following the rotation of the drive shaft 21.

  A wooden spacer 31 is disposed between the front cover plate 13 and the rotating body 24. Another wooden spacer 32 is disposed between the back cover plate 15 and the rotating body 24. Thereby, the rotary body 24 is arrange | positioned in the substantially-central part between the front cover board 13 and the back cover board 15 (refer FIG. 3). The driven shaft 23 is fixed to the rotating body 24 and operates integrally. With these structures, the rotating body 24 does not fall greatly between the front cover plate 13 and the back cover plate 15.

  Further, the outer peripheral surface of the rotating body 24 is flat as described above, and abuts linearly or planarly with the outer peripheral surface of the large-diameter cylindrical portion 21a of the drive shaft 21. The rotating body 24 is not easily tilted between the front cover plate 13 and the back cover plate 15. Therefore, even when the rotating body 24 and the drive shaft 21 are rotating, the posture of the rotating body 24 is maintained, and the rotating body 24 and the drive shaft 21 are in linear or planar contact. The large frictional force described above acts between the drive shaft 21 and the rotating body 24 almost constantly. In addition, the case where both contact | abut in a plane means the case where any one or both of the rotary body 24 and the drive shaft 21 are elastically deformed, and engage in a surface. Therefore, for example, if a rubber member is arranged on the outer periphery of the drive shaft 21, a surface contact state can be obtained by bending the rubber member.

  Further, as shown in FIG. 3, two annular members 33 and 34 made of rubber are disposed on the large-diameter cylindrical portion 21 a of the drive shaft 21. The two annular members 33 and 34 are disposed before and after the portion where the outer peripheral surface of the rotating body 24 abuts in the large-diameter cylindrical portion 21a. The side surface of the peripheral portion of the rotating body 24, that is, the front and back surfaces are sandwiched between the two annular members 33 and 34 (see FIGS. 3 and 4). As a result, the rotating body 24 is less likely to fall down and is more difficult to slip with respect to the rotation of the large-diameter cylindrical portion 21a.

  Incidentally, eight transport holes 36 are formed in the outer peripheral portion of the rotating body 24. The eight transport holes 36 are arranged along the outer peripheral surface of the rotating body 24 at predetermined equiangular intervals (degrees), in this embodiment, at intervals of 45 degrees. The transport hole 36 has a hole diameter that is slightly larger than the outer diameter of the wooden ball 1. When the transport hole 36 is located above the front cover plate 13, and is located in a range of about 270 degrees above in this embodiment, the upper half of the hole is exposed from above the front cover plate 13. Therefore, the wooden ball 1 accommodated in the transport hole 36 is visible from the front when it is located in a range extending from obliquely downward to about 135 degrees from the upper end.

  Moreover, the playground equipment main body 2 has the following circulation paths of the wooden balls 1.

The scale of the sound produced by the second xylophone board 62 may be the same as or different from that of the first xylophone board 61.

  In addition, as a material of the xylophone boards 61 and 62, it is preferable to use what is used for xylophones, such as karin-type materials, such as firewood, an African paddock, and rosewood material, for example. Instead of the xylophone plates 61 and 62, an iron koto plate made of a metal plate may be used.

  Next, operation | movement of the playground equipment which concerns on Embodiment 1 which has the above structure is demonstrated with the how to play. When playing with the play equipment according to Embodiment 1, the wooden ball 1 is placed on the sixth rail member 51. There may be one or more wooden balls 1.

  The wooden ball 1 placed on the sixth rail member 51 moves to the left side in accordance with the downward slope of the sixth rail member 51 and hits the bar member 55. On the right side of the bar member 55, a groove 51c is formed. The wooden ball 1 is smoothly guided into the wooden ball suction hole 43 while being guided by the depth of the groove 51c and the rearwardly falling shape.

  After placing the wooden ball 1 on the sixth rail member 51, the user holds the knob member 22b and turns the knob member 22b clockwise (clockwise). The large-diameter cylindrical portion 21a of the drive shaft 21 rotates clockwise as the knob member 22b rotates. The rotating body 24 is in contact with the large diameter cylindrical portion 21a. The rotating body 24 rotates counterclockwise (counterclockwise) according to the clockwise rotation of the large-diameter cylindrical portion 21a.

  The conveyance hole 36 of the rotator 24 moves to a position overlapping the wooden ball suction hole 43 as the rotator 24 rotates. The groove 51c of the sixth rail member 51 is formed so as to gradually become deeper from the front side to the rear side. Further, the lower surface of the wooden ball suction hole 43 is also formed on a slope whose rear side is lower than the front side. Therefore, the wooden ball 1 in the wooden ball suction hole 43 moves smoothly so as to be sucked into the conveying hole 36 of the rotating body 24. The wooden ball 1 is accommodated in the transport hole 36.

  When the rotating body 24 further rotates according to the rotation of the knob member 22 b, the wooden ball 1 accommodated in the transport hole 36 is lifted together with the transport hole 36. A front cover plate 13 and a back cover plate 15 are erected before and after the rotating body 24. The wooden ball 1 is supported by the front cover plate 13 and the back cover plate 15 so as not to fall, and is lifted without dropping from the transport hole 36. The upper part of the front cover plate 13 is formed so that half of the transport hole 36 is exposed. The user can observe how the wooden ball 1 is rotated and lifted according to the rotation of the knob member 22b.

  The wooden ball 1 that can be lifted together with the rotation of the rotating body 24 abuts the ball striking member 44. The ball bearing member 44 projects toward the approximate center of the wooden ball discharge hole 41. The wooden ball 1 is pushed backward from the conveying hole 36 according to the rotation of the rotating body 24, and moves from the wooden ball discharging hole 41 to the back side of the back cover plate 15 when the conveying hole 36 overlaps the wooden ball discharging hole 41.

Is provided.

  As a result, users such as infants, elementary school children, and elderly people can use conventional three-dimensional wooden playground equipment such as building blocks by virtue of the three-dimensional movement (vertical movement) of the wooden ball 1 and the pleasant tone of the xylophone boards 61 and 62. Compared to a long period of time, you will play without getting bored. Moreover, since the wooden ball 1 moves vertically, it does not require a lot of plane space as a playground equipment.

  The driven shaft hole 26 of the front cover plate 13 and the driven shaft hole 28 of the back cover plate 15 have a long hole shape that is long in the vertical direction. The rotating body 24 is formed so that the outer peripheral surface thereof is in contact with the outer peripheral surface of the large-diameter cylindrical portion 21 a of the drive shaft 21 and the driven shaft 23 is separated from the lower ends of the pair of driven shaft holes 26 and 28. ing. Therefore, the rotating body 24 and the driven shaft 23 are put on the drive shaft 21. Due to the weight of the rotating body 24 and the driven shaft 23, the frictional force acting between the rotating body 24 and the large-diameter cylindrical portion 21a of the drive shaft 21 increases.

  In particular, the rotating body 24 and the drive shaft 21 are integrated, and a pair of spacers 31 and 32 are disposed in front of and behind the rotating body 24. Thereby, it becomes difficult for the rotating body 24 to fall down. In addition, two annular members 33 and 34 made of rubber are disposed in the large-diameter cylindrical portion 21a before and after the portion where the outer peripheral surface of the rotating body 24 abuts. Thereby, even if there is unevenness in the rotation speed of the knob member 22b, for example, the occurrence of slip due to the uneven rotation is suppressed. Moreover, the outer peripheral surface of the rotating body 24 and the large-diameter cylindrical portion 21a of the drive shaft 21 are not in contact at a single point, but are maintained in a linear or planar contact state.

  As a result, the rotating body 24 rotates smoothly together with the drive shaft 21 by the frictional force according to the rotation of the knob member 22b. The rotary body 24 does not need to be attached with, for example, a rubber tape for securing a frictional force with the drive shaft 21 on the outer peripheral surface that is largely exposed as the appearance of the play equipment. There is no loss. Moreover, even if an infant or the like accidentally puts a finger into the conveying hole 36 and the wooden ball suction hole 43 of the rotating body 24, for example, the driving force is caused by the frictional force generated by the weight of the rotating body 24 or the like. In addition, since the force is not large, the finger is not strongly pinched between the rotating body 24 and the front cover plate 13. Therefore, the finger is not cut and it is safe.

  Further, since a ball contact member 44 protruding toward the wooden ball discharge hole 41 of the back cover plate 15 is disposed on the back surface of the front cover plate 13, it is accommodated in the transport hole 36 of the rotating body 24. The wooden ball 1 comes into contact with the ball striking member 44. Accordingly, the wooden ball 1 is pushed backward from the conveying hole 36 by the ball hitting member 44 as the rotating body 24 rotates, and moves smoothly from the wooden ball discharge hole 41 to the back side of the back cover plate 15.

The first reversing member 122 is fixed to the right column 116 at a height position where the lower portion is positioned between the pair of guard portions 123 b of the second rail member 123.

  The first rail member 121 has a flat plate portion 121a having a flat plate shape and a pair of guard portions 121b erected along both ends of the flat plate portion 121a, and has a substantially U-shaped cross-sectional shape. The first rail member 121 is linear and has a length from the right column 116 to the left column 115. A cutout portion 121 d is formed at the right end portion of the first rail member 121. The notch portion 121d is formed in the flat plate portion 121a in a cubic shape having a length slightly shorter than the entire length of the traveling body 101 while leaving the pair of guard portions 121b. The first rail member 121 is fixed to the right column 116 at a height that sandwiches the upper portion of the first reversing member 122 between the pair of guard portions 121b, and the left end portion of the first rail member 121 is the left column. The groove 115a is fixed to the rear 115. The first rail member 121 passes between the middle strut 113 and the rear strut 114, and the passage portion is fixed to the middle strut 113 and the rear strut 114.

  The flat plate portion 121 a of the first rail member 121 is in contact with the upper surface of the fixed plate 117. In the flat plate portion 121a of the first rail member 121, a first opening 136 serving as an opening and a second opening 137 formed as an opening continuous with the first opening 136 are opened. The first opening 136 is located between the second opening 137 and the fixing plate 117. The second opening 137 corresponds to the remainder of the opening.

  The first opening 136 is a rectangular opening having the same width as the distance between the pair of guard portions 121b when viewed from the vertical direction. The width of the first opening 136 is wider than the vehicle width W2 of each set of wheels (for example, 103b and 103c) of the traveling body 101. The first opening 136 is formed from the position of the right end portion on the upper surface of the fixing plate 117 to a position slightly beyond the middle strut 113 and the rear strut 114, and the length thereof is L1 (see FIG. 7).

  The second opening 137 is a rectangular opening having a width that is slightly narrower than the vehicle width W2 of each set of wheels (for example, 103b and 103c) of the traveling body 101. The second opening 137 is wider than the width W <b> 1 of the body 102 of the traveling body 101. The second opening 137 has a length L2 in the left-right direction that is substantially the same as the first opening 136. The flat plate portion 121 a of the first rail member 121 remains on the front side and the rear side of the second opening 137. In this portion of the flat plate portion 121a, a tapered surface 138 is formed at the end on the first opening 136 side, which is inclined obliquely in the left direction from the front surface to the back surface of the flat plate portion 121a.

  As described above, the first rail member 121 is disposed on the lower right side, the second rail member 123 is disposed on the lower side of the first rail member 121, and the second rail member 123 is disposed on the lower side of the second rail member 123. The three rail members 125 and the fourth rail member 126 are disposed downwardly to the right, and the fifth rail member 128 is attached to the lower side of the fourth rail member 126 so that the traveling body 101 travels. Ninety-nine folds are formed between the right column 116 and the left column 115. Further, the left end portion of the fifth rail member 128 is located below the opening of the first rail member 121.

  The play equipment main body 110 includes a handle member 141, a drive shaft 142, a drive rotator 143, a disc 144 as a rotator, a posture stabilization plate 145, and two driven rotators 146 and 147. Have. FIG. 8 is an explanatory diagram showing the disc 144, its drive mechanism, and its periphery.

  Drive shaft holes (not shown) are formed in the upper portion of the front strut 112, the upper portion of the middle strut 113, and the upper portion of the rear strut 114. The drive shaft 142 has a cylindrical rod shape, and is rotatably disposed in these three drive shaft holes. The drive shaft 142 projects forward from the front surface of the front column 112. These three drive shaft holes are opened at a position substantially above the left end of the fifth rail member 128. In other words, it is opened at a position between the left end portion of the fifth rail member 128 and the opening portion of the first rail member 121.

  The handle member 141 includes a handle arm 141a and a knob member 141b. The handle arm 141a has a substantially rectangular shape with a length of 3 to 8 cm. A drive shaft 142 that protrudes forward from the front column 112 is fixed to one end of the handle arm 141a. A knob member 141b is rotatably attached to the other part of the handle arm 141a.

  The circular plate 144 is formed by forming a plywood having a thickness substantially equal to the width of the body 102 of the traveling body 101 in a circular shape with a predetermined radius, like the fixed plate 117. The radius of the disc 144 is slightly smaller than the radius of the half-moon recess 117a of the fixed plate 117. On the outer periphery of the disc 144, eight transport recesses 148 are formed as storage portions in which the traveling body 101 as a moving body is stored. The conveyance recess 148 is formed as a groove having a width and a depth that can accommodate the body 102 of the traveling body 101. That is, in a state where the traveling body 101 is accommodated in the transport recess 148, the wheels 103b, 103c, 104b, and 104c are in a state of sandwiching the fixed plate 117 and the disc 144. As a result, the traveling body 101 moves upward without detaching from the conveyance recess 148. The eight conveying recesses 148 are formed on the outer peripheral portion at substantially equal intervals, so that the disc 144 has an outer shape similar to a gear. The disk 144 is formed with a large circular hole 149 concentric with the outer periphery thereof. In the second embodiment, the circular hole 149 is formed with a radius of about 60 to 80% with respect to the radius of the disc 144.

  The drive rotator 143 includes a rotator main body 143a having a thin disc shape that is thicker than the disc 144, a first rib portion 143b protruding along the outer periphery of one (front side) of the rotator main body 143a, And a second rib portion 143c protruding along the other (rear) outer periphery of the body main body 143a, and is formed in a substantially bobbin shape. The drive rotator 143 is disposed between the middle column 113 and the rear column 114. A drive shaft 142 is fixed to the center of the drive rotator 143. Two O-rings 150 made of rubber are disposed around the rotating body main body 143a.

  The disc 144 is vertically disposed between the middle strut 113 and the rear strut 114 so that the drive rotator 143 is positioned in the circular hole 149. The disc 144 rides on a rubber O-ring 150 wound around the outer periphery of the rotating body main body 143a. In this state, the lower end of the disc 144 is separated from the fixed plate 117 and the fifth rail member 128, and the weight of the disc 144 is applied to the rubber O-ring 150. For example, when the drive rotator 143 is rotated, the frictional force acting between the outer peripheral surface of the rubber O-ring 150 and the inner peripheral surface of the disc 144 increases. The disc 144 rotates following the rotation of the drive rotator 143. Three drive shaft holes into which the drive shaft 142 is inserted are opened at a position substantially above the left end portion of the fifth rail member 128. Therefore, the fifth rail member 128 is positioned below the lower end of the disc 144 in a state where the disc 144 is on the rubber O-ring 150. In addition, in a state where the disc 144 is on the rubber O-ring 150, the outer periphery of the disc 144 and the half-moon recess 117a of the fixed plate 117 are slightly separated from each other. The separation interval is about 1 to 3 mm, which is narrower than the thickness Y of the body 102 of the traveling body 101.

  In a state where the disc 144 is on the rubber O-ring 150, the upper portion of the disc 144 is located in the openings 136 and 137 opened in the first rail member 121. The outer peripheral part of the disk 144 in which the conveyance recessed part 148 is formed is located between the pair of guard parts 121 b of the first rail member 121. When there is a transport recess 148 at the top of the disk 144, the bottom surface of the transport recess 148 at that position is substantially the same height as the back surface of the flat plate portion 121 a of the first rail member 121.

  A wooden spacer (not shown) is disposed between the drive rotator 143 and the rear column 114. A wooden spacer (not shown) is disposed between the drive rotator 143 and the middle column 113. The disc 144 is sandwiched between the first rib portion 143b and the second rib portion 143c of the drive rotating body 143. Thus, when viewed from above the playground equipment, the drive rotator 143 and the disc 144 are arranged in the same plane as the fixed plate 117. Moreover, the disk 144 hardly shakes in the front-rear direction of the play equipment main body 110. When the disc 144 rotates, the outer peripheral portion of the disc 144 rotates smoothly without hitting the flat plate portion 121a of the first rail member 121.

  The posture stabilization plate 145 has substantially the same thickness as the disc 144 and is disposed so as to be flush with the disc 144 and is long in one direction. A pair of push plates (not shown) that are attached to both sides in the thickness direction of the main body and are arranged so that both ends sandwich the disc 144 and are longer than the stabilizing plate main body, as viewed from above Is formed in a shape similar to the capital letter “H”. One driven rotator 146 is pivotally supported on one end side in the longitudinal direction of the posture stabilizing plate 145, and the other driven rotator 147 is pivotally supported on the other end side in the longitudinal direction of the posture stabilizing plate 145. The Rubber O-rings 151 and 152 are wound around the outer periphery of the two driven rotating bodies 146 and 147.

  The posture stabilizing plate 145 is fixed so that the two driven rotators 146 and 147 are in contact with a part of the lower half of the circular hole 149 of the disc 144 in a posture substantially parallel to the playground table 111. The lower portion of the disk 144 is sandwiched between two pairs of push plates and does not shake back and forth. The position of the lower portion of the disc 144 is stabilized at a substantially central position between the pair of guard portions 128b of the fifth rail member 128.

  Further, the posture stabilization plate 145 is a position slightly lower than the height position at which the O-rings 151 and 152 wound around the outer periphery of the two driven rotors 146 and 147 are in contact with the inner peripheral surface of the disc 144. And fixed to the middle column 113 and the rear column 114. The two O-rings 151 and 152 are sandwiched between the respective driven rotors 146 and 147 and the disc 144. Due to the elastic force of these two O-rings 151 and 152, a slight downward force acts on the disc 144. The weight acting on the upper O-ring 150 disposed between the disc 144 and the drive rotating body 143 is increased by the downward force. The frictional force between the disc 144 and the O-ring 150 increases. The disc 144 further rotates following the rotation of the drive rotator 143. Further, since the posture 144 is in contact with the disc 144 on the lower half side of the circular hole 149 from the posture stabilization plate 145, the weight of the disc 144 is not added, and the configuration for posture stabilization can be reduced in size and This does not hinder the rotational driving force of the plate 144.

  Next, operation | movement of the play equipment which concerns on embodiment which has the above structure is demonstrated with how to play. When playing with the playground equipment according to the second embodiment, the traveling body 101 is placed on the fifth rail member 128. A plurality of traveling bodies 101 may be placed on the fifth rail member 128 at a time.

  The traveling body 101 placed on the fifth rail member 128 moves to the left according to the inclination of the fifth rail member 128 to the left. Since the pair of guard portions 128b are disposed on both sides of the flat plate portion 128a of the fifth rail member 128, the traveling body 101 moves to the left without falling from the fifth rail member 128. When the traveling body 101 reaches the left end of the fifth rail member 128, it hits the disk 144.

  After placing the traveling body 101 on the fifth rail member 128, the user holds the knob member 141b with his hand and turns the knob member 141b clockwise (clockwise). The drive shaft 142 and the drive rotator 143 rotate clockwise as the knob member 141b rotates. The disk 144 riding on the drive rotor 143 rotates clockwise (clockwise).

  The conveyance concave portion 148 formed on the outer peripheral portion of the disc 144 moves to a position facing the left end portion of the fifth rail member 128 according to the rotation of the disc 144. The traveling body 101 on the left end portion of the fifth rail member 128 advances to the left due to the inclination of the fifth rail member 128 and is accommodated in the transport recess 148. The body 102 of the traveling body 101 is accommodated in the transport recess 148. At this time, the wheels 103b and 103c sandwich the disc 144. Similarly, the wheels 104b and 104c also sandwich the disc 144.

  When the next traveling body 101 moves to the left on the fifth rail member 128 in a state where the conveyance recess 148 is located immediately above the left end portion of the fifth rail member 128 and the traveling body 101 is accommodated, The front part of the traveling body 101 tries to enter the conveyance recess 148. When the disc 144 rotates in this state, the outer peripheral portion of the disc 144 hits the upper surface of the next traveling body 101. When the disc 144 further rotates, the outer peripheral portion of the disc 144 tends to push down the upper surface of the next traveling body 101. The fifth rail member 128 is pivotally supported by the seesaw base 118 so as to be swingable. The left end portion of the fifth rail member 128 is separated from the playground equipment table 111 to be higher than the height of the wheel of the traveling body 101. Therefore, the left end portion of the fifth rail member 128 rotates counterclockwise in FIG. 8, and the next traveling body 101 advances in the left direction and the disk 144 rotates in the clockwise direction. Then, the left end portion of the fifth rail member 128 is lowered by an amount corresponding to the height of the next traveling body 101. The outer periphery of the disk 144 slides on the upper surface of the traveling body 101 that has been pushed down. When the next conveyance recess 148 rotates in a straight shape at the left end of the fifth rail member 128, the fifth rail member 128 returns to its own balance and is above the left end of the fifth rail member 128. The next traveling body 101 is accommodated in the transport recess 148.

  Therefore, even if the plurality of traveling bodies 101 enter between the fifth rail member 128 and the disk 144, the rotation is not stopped by this, and the disk 144 smoothly follows the rotation of the drive rotating body 143. Rotate to.

  The moving body accommodated in the conveyance recess 148 rotates clockwise together with the disk 144. A fixed plate 117 is erected on the right side of the disc 144. The distance between the half-moon recess 117 a of the fixed plate 117 and the outer peripheral portion of the disc 144 is narrower than the thickness Y of the body 102 of the traveling body 101. The traveling body 101 accommodated in the conveyance recess 148 is sandwiched between the disc 144 and the fixed plate 117, and the wheels 103b and 103c and the wheels 104b and 104c sandwich the disc 144 and the fixed plate 117. Can be lifted without falling. That is, the two sets of wheels 103b, 103c, 104b, and 104c of the traveling body 101 are positioned before and after the disc 144 and the fixed plate 117, and are in a state of sandwiching them.

  When the traveling body 101 is lifted up to a position above the disk 144 according to the rotation of the disk 144, it enters the first opening 136 opened in the first rail member 121 while being accommodated in the transport recess 148. To do. The traveling body 101 enters between the pair of guard portions 121b of the first rail member 121.

  The traveling body 101 that has entered the first opening 136 moves from the first opening 136 toward the second opening 137 in accordance with the clockwise rotation of the disc 144. The second opening 137 is formed with a width that is slightly narrower than the inner space between each pair of wheels (for example, 103b and 103c). The pair of wheels on the front side of the traveling body 101 hits the remaining portion of the flat plate portion 121a remaining on both sides of the second opening 137 (before and after the second opening 137 in the play equipment posture of FIG. 7). A tapered surface 138 is formed at the end of the remaining first opening 136 side. Therefore, when the disc 144 is further rotated clockwise, the pair of wheels (for example, 103b and 103c) on the front side as viewed from the traveling body 101 are pushed by the left wall portion of the conveyance recess 148, and the flat plate portion 121a Get on.

  Further, when the circular plate 144 rotates clockwise, the pair of wheels (for example, 103b and 103c) on the rear side as viewed from the traveling body 101 are pushed by the left wall portion of the conveyance recess 148, and the flat plate portion 121a is also moved. get on. As a result, the entire traveling body 101 gets on the first rail member 121.

  The first rail member 121 is disposed downwardly to the right. The traveling body 101 moves to the right by the inclination of the first rail member 121. A notch 121 d is formed at the right end of the first rail member 121. A pair of wheels (hereinafter referred to as front wheels) on the front side in the traveling direction of the traveling body 101 falls downward from the notch 121d. The front wheel that has fallen down from the notch 121 d hits the first reversing member 122.

  The upper surface of the first reversing member 122 is formed on a slope that is descending to the left. The notch 121d is formed to have a length slightly shorter than the entire length of the traveling body 101. Therefore, a pair of wheels on the rear side in the traveling direction (hereinafter referred to as rear wheels) remains on the first rail member 121 in a state where the front wheel hits the upper surface of the first reversing member 122. The traveling body 101 starts to move to the left according to the inclination of the upper surface of the first reversing member 122 while the rear wheel remains on the first rail member 121. Below the first reversing member 122, a second rail member 123 is disposed downwardly to the left. Therefore, when the rear wheel falls from the first rail member 121, the front wheel moves leftward on the second rail member 123. The traveling body 101 rides on the second rail member 123 with the upper surface and the lower surface of the body 102 interchanged.

  The traveling body 101 riding on the second rail member 123 moves the second rail member 123 disposed to the left downward to the left. The wheels of the traveling body 101 are formed so that the peripheral edge portion is thinner than the central portion thereof, like the head of a thumbtack. Therefore, the traveling body 101 can smoothly move the second rail member 123 without being caught by the guard portion 123b of the bent portion of the S-shape even though the second rail member 123 is formed in the S-shape. Move to the left edge.

  A cutout portion 123 d is formed at the left end portion of the second rail member 123. A second reversing member 124 is disposed below the notch 123d. A third rail member 125 is disposed under the second reversing member 124. Therefore, the traveling body 101 first has its front wheel falling down from the notch 123d and starts traveling on the slope of the second reversing member 124 to the right, and then the rear wheel falls down from the notch 123d. The traveling body 101 rides on the third rail member 125 with the upper surface and the lower surface of the body 102 interchanged.

  A fourth rail member 126 and a sixth rail member 129 are disposed on the right side of the third rail member 125. When the support plate 133 is in the standing posture, the flat plate portion 125a of the third rail member 125 and the flat plate portion 126a of the fourth rail member 126 form a substantially continuous surface. When the support plate 133 is rotated counterclockwise by holding the handle 135, the flat plate portion 125a of the third rail member 125 and the flat plate portion 129a of the sixth rail member 129 form a substantially continuous surface.

  When the support plate 133 is tilted, the traveling body 101 moves from the third rail member 125 to the sixth rail member 129 and runs out of the playground equipment 111 from the right end portion of the sixth rail member 129.

  When the support plate 133 is held in the standing posture, the traveling body 101 moves from the third rail member 125 to the fourth rail member 126. The fourth rail member 126 is disposed downwardly to the right. The traveling body 101 further moves to the right on the fourth rail member 126.

  A cutout portion 126 d is formed at the right end portion of the fourth rail member 126. A third reversing member 127 is disposed below the notch 126d. A fifth rail member 128 is disposed below the third reversing member 127. Therefore, the traveling body 101 first has its front wheel falling down from the notch 126d, and after the front wheel that has fallen begins to travel to the left on the slope of the third reversing member 127 to the left, the rear wheel descends from the notch 126d. fall into. The traveling body 101 rides on the fifth rail member 128 with the upper surface and the lower surface of the body 102 interchanged.

  The fifth rail member 128 is disposed downwardly to the left. The traveling body 101 moves to the left on the fifth rail member 128. The traveling body 101 moves to the left end portion of the fifth rail member 128 and hits the disk 144.

  At this time, if the knob member 141b is rotated clockwise, the traveling body 101 is accommodated again in the conveyance recess 148 of the disk 144 that rotates clockwise. The traveling body 101 is lifted again by the disk 144. The lifted traveling body 101 moves on the first rail member 121, the second rail member 123, the third rail member 125, the fourth rail member 126, and the fifth rail member 128. The traveling body 101 hits the disk 144 again. The traveling body 101 continues to circulate on the traveling path constituted by the plurality of rail members and the like.

  The user enjoys watching the traveling body 101 lifted by the disk 144 simply by turning the knob member 141b around the drive shaft 142, and the traveling body 101 is provided with a plurality of rails arranged in ninety-nine folds. It is possible to enjoy the state of traveling on the members 121, 123, 125, 126, and 128 while switching the top and bottom of the members 121, 123, 125, 126, and 128. The user can continuously enjoy this three-dimensional movement by continuing to turn the knob member 141b. If a plurality of traveling bodies 101 are used, it is possible to simultaneously enjoy the state in which the traveling body 101 is lifted and the state in which the traveling body 101 travels. In addition, the user can enjoy the state in which the traveling body 101 runs vigorously from the traveling path by tilting the support plate 133.

  As described above, in the play equipment according to this embodiment, the traveling body 101 is lifted by the disk 144 that rotates according to the rotation of the handle member 141, and the lifted traveling body 101 is moved to the plurality of rail members 121, 123, 125, 126. , 128, etc., and is returned to the bottom of the disk 144. Further, the traveling body 101 travels on the plurality of rail members 121, 123, 125, 126, and 128 while changing the front and back sides thereof.

  As a result, a user such as an infant, an elementary school student, or an elderly person can enjoy a state in which the traveling body 101 is three-dimensionally lifted by the disc 144 and a state in which the traveling body 101 circulates. Compared to wooden playground equipment, it will play for a long time without getting tired. Moreover, since the traveling body 101 moves vertically, it does not require a lot of plane space as a playground equipment.

  In addition, the disk 144 rides on the drive rotator 143. In addition, a downward force is applied to the disc 144 by the two driven rotors 146 and 147. Due to the weight of the disc 144 and the downward biasing force, the frictional force acting between the disc 144 and the O-ring 150 of the drive rotor 143 increases. Therefore, for example, even if the rotation speed of the drive rotator 143 is uneven, the occurrence of slip due to the rotation unevenness is suppressed, and the disk 144 rotates smoothly according to the rotation of the drive rotator 143.

  Moreover, even if an infant or the like accidentally puts his / her finger into the conveyance recess 148 of the disc 144, the finger is not strongly pinched between the disc 144 and the middle support post 113 or the like. Therefore, the finger is not cut and it is safe.

The ball stopper plate 214 is erected between the front bearing plate 212 and the rear bearing plate 213. The ball stopper plate 214 is erected along the right end of the front bearing plate 212 and the right end of the rear bearing plate 213, and forms a U-shape when viewed from above with both the receiving plates 212 and 213.
The

  The upper part of the front bearing plate 212 and the upper part of the rear bearing plate 213 are fixed by the handle bar 222 above the ball stopper plate 214. The playground equipment body 202 can be lifted and transported in a well-balanced manner by holding the handle bar 222 by hand. Even if the play equipment main body 202 is lifted by holding only the handle bar 222, the play equipment main body 202 is not broken.

  The link table 215 is erected at the left end portion of the playground equipment table 211. The link base 215 is formed with a vertically long vertical groove portion 215a on the side surface (on the right side in FIG. 9) facing the front bearing plate 212 and the rear bearing plate 213. The height of the link base 215 is higher than the lower part of the front bearing plate 212. A pair of through holes are formed in the upper part of the link base 215. A vertical groove 215a is located between the pair of through holes. The pair of through holes are opened at a position higher than the lower end of the link hole 221 with the playground table 211 as a reference. A through shaft 223 is inserted into the pair of through holes.

  The inclined member 216 includes an inclined front plate 216a, an inclined rear plate 216b, an inclined upper surface plate 216c, and four xylophone plates 224. The inclined front plate 216 a is erected on the front side in the left half of the playground equipment table 211. The left end of the inclined front plate 216a overlaps the link base 215 when viewed from the front. The upper surface of the inclined front plate 216a has a stepped shape in which the height gradually decreases from the link base 215 toward the front bearing plate 212. The inclined back plate 216 b has the same outer shape as the inclined front plate 216 a and is erected on the rear side in the left half of the playground equipment table 211. The link table 215 is sandwiched between the inclined front plate 216a and the inclined back plate 216b. The inclined upper surface plate 216c is disposed between the uppermost portion of the inclined front plate 216a having a stepped shape and the uppermost portion of the inclined rear plate 216b having a stepped shape. A plurality of xylophone plates 224 are disposed on the remaining steps of the remaining inclined front plate 216a and the remaining steps of the inclined rear plate 216b. The inclined front plate 216a and the inclined rear plate 216b are blocked by the inclined upper surface plate 216c and the plurality of xylophone plates 224. The upper surface of the inclined member 216 is an inclined surface whose height decreases stepwise from the left side to the right side.

The plurality of xylophone plates 224 are fastened with screws 225 to an inclined front plate 216a and an inclined rear plate 216b that are provided substantially in parallel. In this case, it is necessary to make the intervals between the two screw holes opened in the plurality of xylophone plates 224 uniform. In the xylophone used as a percussion instrument, the interval between the two holes to which the plurality of xylophone plates 224 are screwed is different depending on the scale emitted by each xylophone plate 224. For this reason, if the interval between the two holes for screwing is determined, the scale of the xylophone 224 may be uniquely determined. When a plurality of xylophone plates 224 having substantially the same size are screwed to the inclined front plate 216a and the inclined rear plate 216b erected substantially in parallel as described above, the musical scale of the plurality of xylophone plates 224 is conventional. If there is, it is thought that it will become one kind. However, by adjusting the depths of the depressions formed on the back side of the plurality of xylophone plates 224 according to the scale, the pitches of the plurality of xylophone plates 224 are different from each other while keeping the distance between the two holes for screwing. It can be a musical scale. This makes it possible to efficiently form and fix the plurality of xylophone plates 224, and eliminates the need for various jigs for NC processing and jigs for screwing. The molding method and the fixing method of the plurality of xylophone plates 224 can also be applied to xylophone toys.

To position. Therefore, the rail bar 242 is in a left-down posture.

  FIG. 14 is a front view showing the carrier 244 and its peripheral part. The transport body 244 has a transport body main body 244a. The transport body main body 244a has a shape imitating a bird in this embodiment. As shown in FIG. 9, the bird faces the left side of the playground equipment main body 202. A slit 244b is formed in the lower part of the transport body main body 244a. The slit 244b is slightly wider than the rail bar 242 and is formed along the front-rear direction (left-right direction in FIG. 14) of the transport body main body 244a.

  Two roller bodies 251 are disposed in the upper part of the slit 244b. The roller body 251 has a roller body main body 251a and a pair of rib portions 251b, and has a substantially bobbin shape. The length of the roller body main body 251a in the rotation axis direction is slightly longer than the width in the front-rear direction of the track protrusion 242b of the rail bar 242.

  The two roller bodies 251 are arranged side by side before and after the transport body main body 244a in the moving direction. The two roller bodies 251 rotate together with a roller shaft 252 that is rotatably supported by the transport body main body 244a. The roller shaft 252 is a rotation shaft that is rotatably disposed on the transport body main body 244a. The roller of the moving body is composed of the roller shaft 252 and the roller body 251.

  The transport body 244 serving as a moving body is disposed on the rail bar 242 so that the two roller bodies 251 come into contact with the rail bar 242. The outer peripheral surface of the roller body 251a is in contact with the upper surface of the track protrusion 242b of the rail bar 242, and the track protrusion 242b is positioned between the pair of rib portions 251b.

  Of the two roller bodies 251, a cylindrical body (not shown) is disposed on the outer periphery of the roller body 251 a of the roller body 251 on the front side of the transport body main body 244 a (left side in the case of the play equipment body 202, hereinafter referred to as the front roller body). The rubber material is wound. As a result, the frictional force acting between the front roller body and the track protrusion 242b is increased, and slipping is difficult.

  Both ends of the roller shaft 252 that rotates together with the front roller body protrude outward from the transport body main body 244a. A pair of wing members 253 as a governor body that functions as a governor function that slows down the moving speed is fixed to both projecting ends. The pair of wing members 253 are fixed to the roller shaft 252 in a posture shifted by 180 degrees in order to balance the moving body. The pair of wing members 253 rotate together with the roller shaft 252 of the front roller body.

  Further, the slit 244b of the transport body main body 244a is formed to a depth at which the lower end of the transport body main body 244a protrudes below the rail bar 242 in a state where the two roller bodies 251 are placed on the rail bar 242. Is done. A holding plate 254 that closes the lower side of the slit 244b is fixed to the lower portion of the transport body main body 244a. A pair of second hook members 245 are fixed to the holding plate 254.

  The second hook member 245 has an outer shape similar to a substantially L-shaped fishhook similar to the first hook member 233. However, there is no notch. Thus, the 2nd hook member 245 and the 1st hook member 233 can be manufactured by one metal mold | die by making the 2nd hook member 245 into substantially the same shape as the 1st hook member 233.

  The pair of second hook members 245 are fixed below the holding plate 254. The pair of second hook members 245 are fixed apart from each other at an interval narrower than the diameter of the wooden ball 201 in the front-rear direction of the play equipment main body 202. The distance between the pair of second hook members 245 is substantially the same as the distance between the pair of first hook members 233. Therefore, the wooden ball 201 can be held between the pair of second hook members 245. A pair of tip portions of the pair of second hook members 245 come below the wooden ball 201. At this time, the front and rear surfaces of the wooden ball 201 protrude to the outside of the pair of second hook members 245 or are positioned within the thickness of the second hook member 245.

  Returning to FIG. 9 and FIG. 13, the description will be continued. The claw stick 246 has a cylindrical shape. The claw stick 246 is disposed so as to protrude rightward from the link base 215 just below one end of the rail bar 242. The tip of the claw stick 246 is positioned above the right end portion of the inclined upper surface plate 216c at the uppermost stage of the inclined member 216. The claw stick 246 has such a length that the position of its tip is substantially the same as the right end of the pair of second hook members 245 when the transport body 244 moves to the leftmost side. Further, the claw stick 246 is disposed at a height at which a tip portion thereof is positioned between the pair of second hook members 245 when the transport body 244 moves to the leftmost side.

  Next, operation | movement of the playground equipment which concerns on Embodiment 3 which has the above structure is demonstrated with the how to play. When playing with the play equipment according to Embodiment 3, the wooden ball 201 is placed on the rail member 217. There may be one or more wooden balls 201.

  The wooden ball 201 placed on the rail member 217 moves to the right according to the downward slope of the rail member 217 and stops by hitting the inclined body 229 disposed on the left surface of the ball stopper plate 214. As shown in FIG. 11, the wooden ball 201 stops at a position below the drive shaft 231.

  After placing the wooden ball 201 on the rail member 217, the user holds the knob member 236 and turns the knob member 236 counterclockwise (counterclockwise). The handle plate 235 rotates counterclockwise. As the handle plate 235 rotates, the rotating body 232 and the two sets of first hook members 233 rotate counterclockwise around the drive shaft 231. The wooden ball 201 stopped at a position below the drive shaft 231 is sandwiched and accommodated between a pair of first hook members 233 descending counterclockwise from above.

  When the handle plate 235 further rotates, the wooden ball 201 is lifted counterclockwise by the pair of first hook members 233, passes over the drive shaft 231, and hits the fence portion 234 d of the ball placing plate 234. That is, the lower part of the wooden ball 201 hits the fence part 234d of the ball placing plate 234. If the handle plate 235 further rotates after the wooden ball 201 hits the fence portion 234d of the ball rest plate 234, the pair of first hook members 233 attempt to move downward according to the rotation, and the fence portion 234d of the ball rest plate 234 By trying to support the wooden ball 201, the wooden ball 201 comes off between the pair of first hook members 233 and jumps up. The wooden ball 201 rolls on the ball rest plate 234 between the pair of fence portions 234d and 234e, and finally stops stably on the recess portion 234c.

  The pair of first hook members 233 is formed with a notch groove 233a. The pair of first hook members 233 opens smoothly when the wooden ball 201 comes out. As a result, the wooden ball 201 can come out from between the pair of first hook members 233 relatively smoothly, and the handle plate 235 can be turned even by a weak baby. The pair of first hook members 233 after the wooden ball 201 is removed passes through the gap G formed between the ball placing plate upper part 234b, the front bearing plate 212, and the rear bearing plate 213, and rotates the handle plate 235. Therefore it rotates.

  In addition, the wooden ball 201 comes off between the pair of first hook members 233 and jumps up. Therefore, even if another wooden ball 201 is already on the ball rest plate 234, the jumped wooden ball 201 pushes the other wooden ball 201 at the momentum and rides on the ball rest plate 234. be able to. A plurality of wooden balls 201 can ride on the ball resting plate 234 at the same time.

  Further, the wooden ball 201 may fall from the ball resting plate 234 or the like. The upper surface of the inclined body 229 is disposed downwardly to the left. A rail member 217 is disposed downwardly to the right. Therefore, the wooden ball 201 dropped from the ball rest plate 234 stops at a position below the drive shaft 231. Therefore, the two sets of first hook members 233 can lift the dropped wooden balls 201 during the next rotation.

  When the handle plate 235 rotates, the link arm 243 reciprocates in the vertical direction. Further, the right end (other end) of the rail bar 242 also reciprocates in the vertical direction together with the link arm 243. When the handle plate 235 rotates once, the right end portions of the link arm 243 and the rail bar 242 reciprocate up and down once.

  When the handle plate 235 is rotated halfway to reach the state shown in FIG. 13, the transport body 244 moves to the left. Then, when the knob member 236 is moved to its lowest position as shown in FIG. 9 by further half-turning, the rail bar 242 assumes a downwardly inclined posture. When the rail bar 242 is in the right-down posture, the transport body 244 moves to the right according to the inclination of the rail bar 242. The ball resting plate 234 is disposed on the lower right at substantially the same angle as the angle when the rail bar 242 is lowered most. Therefore, the front ends of the pair of second hook members 245 attached under the transport body 244 enter a gap between the ball placing plate upper part 234b, the front bearing plate 212, and the rear bearing plate 213. The transport body 244 stops in a state where the pair of second hook members 245 are in contact with the wooden balls 201. At this time, the front ends of the pair of second hook members 245 smoothly enter under the wooden ball 201 located on the leftmost side.

  When the handle plate 235 is further rotated halfway, the right end portions of the link arm 243 and the rail bar 242 are raised as shown in FIG. The wooden ball 201 riding on the ball resting plate 234 is supported by the tip portions of the pair of second hook members 245 and lifted together with the transport body 244. The wooden ball 201 is sandwiched between the pair of second hook members 245 and lifted.

  Further, when the inclination of the rail bar 242 to the left decreases, the transport body 244 starts to move in the left direction according to the inclination of the rail bar 242. A pair of wing members 253 are fixed to the front roller body. The pair of wing members 253 function as a governor. Accordingly, the rotation of the front roller body is suppressed by the weight of the pair of wing members 253. The transport body 244 is provided with two roller bodies 251 along the moving direction thereof. The posture of the carrier 244 is stable with respect to the rail bar 242. As a result, the transport body 244 does not start moving to the left until the inclination of the rail bar 242 to the left increases to a certain extent, and is also slowly and stably limited by the weight of the pair of wing members 253. Then, it moves smoothly on the rail bar 242. Thus, the transport body 244 slowly rises and moves regardless of the speed of raising and lowering the rail bar 242, so that the wooden ball 201 accommodated between the pair of second hook members 245 is transported by the transport body. It does not fall during the movement of 244.

  When the transport body 244 moves close to the link base 215, the wooden ball 201 held between the pair of second hook members 245 hits the tip of the claw stick 246. The claw stick 246 protrudes with a length such that when the transport body 244 moves to the leftmost side, the position of its tip is substantially the same position as the right end of the pair of second hook members 245. The transport body 244 is provided with two roller bodies 251 along the moving direction thereof. Therefore, after the wooden ball 201 hits the tip of the claw stick 246, the transport body 244 moves further to the left without completely stopping. The transport body 244 moves further to the left after the wooden ball 201 hits the tip of the claw stick 246 by the rotation of the pair of wing members 253 that function as a cover. As a result, the wooden ball 201 is surely dropped from between the pair of second hook members 245 so as to be pushed rightward by the ball stick 246. The wooden ball 201 always falls almost directly below the tip of the claw stick 246.

  A plurality of xylophone boards 224 are arranged below the tip of the claw stick 246 in a right-down direction. The wooden ball 201 dropped from between the pair of second hook members 245 hits the plurality of xylophone boards 224. The wooden balls 201 dropped so as to be pushed rightward by the ball striking rod 246 from between the pair of second hook members 245 hit the plurality of xylophone boards 224 in order while slowly moving to the right. As a result, the wooden ball 201 reliably hits a plurality of xylophone plates 224 in order and automatically emits a sound of a predetermined rhythm and tone color.

  After hitting the plurality of xylophone boards 224 in order, the wooden ball 201 moves onto the rail member 217. The wooden ball 201 rolls on the rail member 217 according to the downward slope of the rail member 217 and stops at a position below the drive shaft 231.

  As described above, the user rotates the handle plate 235 while holding the knob member 236, whereby the wooden ball 201 is lifted to the ball placing plate 234 by the pair of first hook members 233, and the pair of second hook members 245. Of the plurality of xylophone plates 224 and rail members 217 (circulation path) that are lifted from the ball resting plate 234, transported slowly at a stable speed by the transport body 244, dropped from the transport body 244, and arranged to the right. You can observe the situation of moving back and returning. The wooden ball 201 circulates smoothly through this conveyance path. Further, the plurality of xylophone 224 hits the wooden ball 201 to emit a comfortable sound of a predetermined scale. The user can continuously enjoy the complicated mechanical and three-dimensional controlled movement and tone of the wooden ball 201 by continuing to rotate the handle plate 235. If a plurality of wooden balls 201 are used, the movement and sound of the wooden balls 201 can be enjoyed simultaneously.

  As a result, a user such as an infant, an elementary school student, or an elderly person has a complicated mechanical and three-dimensional movement of the above-described wooden ball 201 and a state in which a bird carries the wooden ball 201 riding on the ball placing plate 234. The comfortable tone of the xylophone 224 allows the player to play without getting tired over a long period of time compared to a conventional wooden playground equipment such as a building block. Moreover, since the wooden ball 201 moves vertically, a lot of plane space is not required as a playground equipment.

  The rotating body 232 and the two sets of first hook members 233 are disposed at a portion surrounded by the front bearing plate 212, the rear bearing plate 213, the ball stopper plate 214, and the ball placing plate 234. Therefore, it is difficult for an infant or the like to touch the rotating first hook member 233, for example, and it is safe.
