Description

  The present invention relates to a display educational toy suitable for a toy that children and infants play by riding and pushing, such as a toy for children, a handcart, and a playground equipment called “katakata”.

  For children's (including infants) vehicle toys, wheelbarrows, playground equipment for walking, etc., there are a wide variety of educational toys that attract children's attention and interest and nurture their children's attention and concentration. It is used. For example, there is one that moves a doll or the like up and down as the vehicle travels.

  In Patent Document 1, a plurality of gears can be fixed to a support surface by, for example, magnets, and each gear is meshed to be rotatable. For example, a reflective display sheet is attached to the gears, and these are rotated in conjunction with each other. A display device is shown. This display device is for signboards and advertisements, but can be used as a toy in which a child patterns a gear fixed to a support surface and rotates them.

Special table 2004-504644

  For things that move or rotate a doll, the drive mechanism is usually hidden in the body of the vehicle, and the child quickly gets bored with simple movements such as the doll. lose. For this reason, it is not enough to develop children's attention, concentration or thinking (intellect).

  The one shown in Patent Document 1 is to fix each gear to a support surface or to attach a display sheet to each gear, so it is too complicated to assemble especially for young children and young children close to infants, There is a problem. There is also a problem that the gears and the display sheet are exposed so that they are not suitable for use in vehicles used outdoors.

  The present invention has been made in view of such circumstances, so that the internal movement can be seen from the outside to attract attention and interest of the infant and the child, and the infant and the child follow the movement. The purpose is to provide a display educational toy that can cultivate power, concentration or intelligence, and is also suitable for vehicles used outdoors.

  According to the present invention, the object is to provide a plurality of gears that rotate in synchronization with each other, a case that surrounds the gears and that can be seen through the front side facing the gears, and a front side of the case that is provided on the gears and that faces the front side A plurality of radial projecting walls, a decorative disk that is loaded between the gear and the case and is guided by the projecting wall provided on the gear by the rotation of the gear and the inner wall of the case to roll, and an adjacent gear A pair of swingable guide claws that project from both sides of the meshing portion to guide the meshing portion and guide the disk, and guide the disk to the adjacent gear by oscillating and interlocking the guide claws in opposite directions. And a display-like educational toy characterized by comprising a balance lever.

  Since the front side of the case can be seen through, the inside can be seen through the front side. Not only does the gear rotate inside the case, but also the guide pawls, the balance lever, etc. are intermittently swung in conjunction with the disk, making the movement complex and interesting. For this reason, infants can naturally develop their attention and concentration by chasing those movements, and also develop the ability to think (intelligence) because they can understand movements such as disks and predict movements. Is possible.

  Since gears, disks, guide claws, balance arms, etc. are housed in the case, they are suitable for outdoor use and suitable for use in a vehicle.

  If the case can be seen through not only from the front side, but also from the back side, the inside can be seen from the back side, so that the effect of the present invention is further increased. If three or more gears are arranged, the range of movement of the disk becomes wider and it becomes easier to attract the attention of the infant. In this case, two or more guide claws are required, and two or more balance levers are also required (Claim 2).

  The case is horizontally long and accommodates a plurality of gears side by side, and this case can be attached to a handwheel handle having a substantially inverted U shape in rear view attached to the rear part of a vehicle for children (including infants) ( Claim 3). In this case, the hand handle can be reinforced by the case. The case may be a backrest behind the seating seat (claim 4).

  In order to rotate the gear, a knob for manually rotating and driving one gear can be disposed on the back side of the case. In this case, the front side of the case can be shown to the infant and the guardian can turn the knob from the back. The gear may be rotated by other means.

  1 and 2, reference numeral 10 denotes a vehicle body, which has two steering front wheels 12 and 12 and two rear wheels 14 and 14. Reference numeral 16 denotes a steering handle, and 18 denotes a seat. The seating seat 18 is located near the center of the vehicle body 10, and when the child sits straddling the seating seat 18, both feet reach the road surface outside the vehicle body 10. That is, the child can travel by putting his / her feet on both outer sides of the vehicle body 10 and kicking the road surface.

  The front portion of the vehicle body 10 is covered with a transparent cover 20 having a substantially spherical shape, and a toy (not shown) such as a doll accommodated in the cover 20 can be seen through. The shaft of the steering handle 16 passes through the upper part of the cover 20. Three buttons 22 are attached to the cover 20 so as to surround the steering handle 16 from the left and right and from the front. These buttons 22 can move the toy inside the cover 20.

  Between the rear wheels 14, 14, a manual operation knob 24 for adjusting the braking force applied to the rear wheels 14, 14 is disposed (FIG. 2). Reference numeral 26 denotes a plate member extending downward and rearward from between the rear wheels 14 and 14. This plate member 26 comes into contact with the road surface when the front portion of the vehicle body 10 is lifted by a predetermined amount or more, and prevents excessive lift.

  A push handle 28 that stands up from the rear of the seating seat 18 is attached to the rear portion of the vehicle body 10. The hand handle 28 has a substantially inverted U shape when viewed from the rear, and a display educational toy 30 according to the present invention is attached at a distance from the upper grip portion 28a. In this embodiment, the display educational toy 30 is integrated with the grip portion 28a, and the integrated unit 32 is fixed to the upper ends of the left and right pole portions 28b, 28b.

  The unit 32 of the educational toy 30 and the grip portion 28a has a front / rear split case 34 as shown in FIG. The case 34 is formed by joining a transparent front half body 34a and a rear half body 34b made of a transparent or translucent resin that can be seen through with an appropriate number of screws. Therefore, the inside can be seen through from the front side of the case 34 through the front half 34a. The latter half 34b does not necessarily need to be seen through, but if it can be seen through, the inside can be seen from the rear (back side), which is more interesting.

  In the case 34, as shown in FIG. 3, three gears 36 (36a, 36b, 36c) of the same number of teeth arranged in the width direction of the vehicle body 10 and the front side of the gear 36, that is, the first half of the case 34 A plurality of radial projecting walls 38 projecting on the body 34a side, two decorative disks 40 (40a, 40b) loaded between the gear 36 and the case 34 and transferred by the rotation of the gear 36, Guide claws 42 (42a, 42b), a balance lever 44 and the like which will be described later are accommodated.

  In this embodiment, the protruding wall 38 of the gear 36 protrudes in a cross shape around the center of the gear 36. On the inner surface of the rear half 34b of the case 34, there are three bosses 46 that rotatably hold the gear 36, and a plurality of arc-shaped guide walls 48 that protrude so as to surround the outer periphery of the gear 36 with a sufficient space therebetween. And a plurality of circular arc-shaped disk support walls 50 projecting between the guide walls 48 and the outer periphery of the gear 36 and having substantially the same height as the surface of the gear 36 (the surface on the front half 34a side of the case 34). ing. Here, the guide wall 48 is formed separately from the inner peripheral wall of the case 34, but the independent guide wall 48 may be omitted by using these as the same.

  A knob 52 is engaged and fixed to the gear 36a at the left end when viewed from the front through the rear half 34b of the case 34 from the rear. The knob 52 projects rearward from the case 34 as shown in FIG. When the knob 52 is manually rotated, the gear 36a is rotated, and the other gears 36b and 36c engaged therewith are also rotated in synchronization with each other.

  The disk 40 is loaded with a sufficient margin between the gear 36 and the front half 34a of the case 34 in a space surrounded by the protruding wall 38 and the guide wall 48 of the gear 36. The disk support wall 50 prevents the disk 40 from falling between the gear 36 and the guide wall 48. As shown in FIG. 4, the three gears 36 are meshed in phase so that the protruding walls 38 are substantially aligned, and the two disks 40a and 40b are symmetrical about the central gear 36b. Is loaded. The surface of these discs 40 should be colored, drawn, or provided with a reflective display to make it easier for children to get interested.

  The guide claws 42 (42a, 42b) project from the guide walls 48 on both sides so as to face the meshing portions of the adjacent gears 36, and their tips can swing. That is, a pair of guide claws 42 (42a, 42b) are provided between the gears 36a and 36b, and a pair is provided between the gears 36b and 36c.

  The pair of guide claws 42 (42a, 42b) are interlocked by the balance levers 44, 44. As shown in FIG. 5, the lever 44 is substantially S-shaped and is pivotally supported by the rear half 34b of the case 34 at the center of the lever 44 on the back side of the meshing portion. At both ends of the lever 44, long guide holes 44a, 44b are formed in the direction of the swing center of the lever 44, and projections 54 (FIG. 5) project from the guide holes 44a, 44b on the swing end side of the guide claw 42. ) Is in attendance.

  Therefore, when the upper guide claw 42a swings to the right in FIG. 5, the lower guide claw 42b swings to the left. That is, the guide claws 42a and 42b swing in opposite directions. Therefore, when the disk 40 is moved by the rotation of the gear 36 to push open the one guide claw 42a or 42b, the other guide claw 42b or 42a is interlocked and reversed. Swing to the side.

  Next, the operation will be described with reference to FIGS. First, it is assumed that the disks 40a and 40b are on the gears 36a and 36c as shown in FIG. In this state, if the knob 52 is rotated counterclockwise (clockwise in FIG. 4) from the rear, the gears 36a and 36c rotate in the same direction (clockwise), and the disks 40a and 40b push against the protruding wall 38. Further, it is guided by the guide wall 48 and moves while rotating (FIG. 6). Then, the disk 40a pushes open the left guide claw 42a in FIG. 7 (FIG. 7), falls between the projecting walls 38 of the gears 36a and 36b, and is sent below the intermediate gear 36b by the guide claw 42b (see FIG. 7). 8 and 9).

  At this time, the disk 40b is pushed open by tilting the right guide claw 42b to the left (FIG. 7) and pushed up between the gears 36c, 36b (FIG. 8). Then, the disk 40b is sent above the intermediate gear 36b by the guide claw 42a that has fallen to the right above (FIG. 9).

  When the knob 52 is further rotated in the same direction, the disk 40a pushes and opens the right guide claw 42b, and the disk 40b pushes and opens the left guide claw 42a (FIG. 10), moving while rotating to the gears 36c and 36a, respectively. Go (Figure 11). When the knob 52 is rotated in this manner, the disks 40a and 40b move around the gear 36 in an eight-letter shape (see FIG. 1). At this time, the disk 40 rotates in contact with the guide wall 48 or the protruding wall 38.

  Since the entire surface of the case 34 is transparent, the disk 40 and the gear 36 can be visually recognized from the outside, and by following these movements, the child's interest can be strongly attracted, which is useful for concentration training. Further, if the rotation direction of the knob 52 is reversed, the movement of the disk 40 is also reversed, and by predicting the movement of the disk 40, the child's intelligence (thinking ability) can be nurtured. If a color pattern or picture that draws children's attention is drawn on the disk 40, the effect will be even greater.
