Description

  The present invention relates to a rocking toy, that is, a vehicle toy that moves forward when an infant rides and rocks back and forth.

  2. Description of the Related Art A wooden horse that can swing back and forth is known as a toy for children to play across. Conventional wooden horses simply swing back and forth, but toys with a function of moving forward by swinging have been proposed.

  For example, it has an arc-shaped saddle with a wooden horse fixed to the upper part and a saddle attached with an upper fulcrum to the lower surface of the body of the wooden horse with a hinge, so that the lower end of the saddle reaches the ground on the lower surface of the arc-shaped saddle An advanced forward horse is disclosed (see, for example, Patent Document 1).

  In addition, a plurality of rollers are pivotally supported at a substantially central portion of the cage on which the body of the toy carved in the shape of an animal is mounted, and only swinging backward is allowed forward and backward of the cage. An oscillating vehicle toy that pivotally supports a rotating body is disclosed (for example, see Patent Document 2).

JP-A-6-246071 Registered Utility Model No. 3087398

  However, since the forward wooden horse described in Patent Document 1 is configured to move forward by sliding the kite, the moving distance by one swing is short and the propulsive force is poor. Further, when used indoors, the floor may be damaged. On the other hand, even when used outdoors, there is a possibility that the lower end of the ridge is buried in the ground and does not move forward when the ground is soft. In other words, the forward wooden horse has a great restriction on the place to use it.

  Moreover, since the rocking vehicle toy described in Patent Document 2 is configured to move forward by using a slight rotation of the rotating body, the distance to move forward by one swing is short and lacks fun. .

  In view of the above problems, an object of the present invention is to provide a swing propulsion toy that can move a sufficiently long distance with a single swing with few restrictions on the place to be used.

  A first device for solving the above problems includes a toy main body having a downwardly convex curved portion at a lower end, a plurality of left and right pairs of wheels that are arranged in front and rear of the curved portion and pivotally supported, and an upper end portion. Is a pivoting toy that is supported by the toy main body so as to be swingable and extends rearward and downward until it reaches a position lower than the lower edge of the toy main body, and a spring that biases the front to the front. It is.

  The second device is the swing propulsion toy of the first device, and the lower end of the bag is covered with a rubber cover.

  A third device is a swinging propulsion toy according to the first or second device formed by imitating an animal.

  According to the first device, when the toy main body is swung back and forth using the curved portion, when the center of gravity is moved rearward, the bag stretches the placement surface of the toy, and the wheel rotates to advance the toy main body. Thereafter, when the center of gravity moves forward, the spring-biased kite returns to the lowest position, and the wheels rotate and the swinging propulsion toy continues to advance. Therefore, the swing propulsion toy swings and moves forward only by the infant riding and repeatedly moving the center of gravity back and forth. Since a large driving force can be obtained by one swing, the playfulness of the infant can be satisfied.

  According to the second device, since the lower end of the heel is covered with the rubber cover, the friction is large and the lower end of the heel is difficult to slide on the mounting surface. Therefore, the rocking propulsion toy can effectively obtain a propulsive force. Further, since the cover has elasticity, even when the swing propulsion toy is used on the floor or other indoor placement surface, the possibility of damaging the placement surface is reduced.

  According to the third device, since the swing propulsion toy is formed to imitate an animal, the swing propulsion toy becomes a more attractive toy that stimulates the playfulness of an infant.

A plurality of pairs of left and right wheels 20 that are pivotally supported, and a flange 21 that is pivotally supported at the upper end of the toy body 10 so as to be swingable and extends below the lower edge of the toy body 10. And a spring 22 for urging the flange 21 forward.

  The toy body 10 includes a side plate 11, a seat bottom plate 12, a seat front plate 13, a seat rear plate 14, a back plate 15, a vertical plate 16, a front joint plate 17, and a rear joint plate 18.

  The two left and right side plates 11 and 11 are arranged in a C-shape when viewed from the front, with the upper and lower sides of the upper and lower approximately center being cut into a rectangle. The front and rear substantially center of the lower end of the side plate 11 is formed in a substantially arc shape that curves upward and convex downward, and constitutes a curved portion 10 a of the toy body 10. The toy main body 10 can swing back and forth so that the bending portion 10a is in contact with the mounting surface S, and does not have protruding portions that hinder the swinging of the bending portion 10a.

  A seat bottom plate 12 at the lower end, a seat front plate 13 at the front end, and a seat rear plate 14 at the rear end are fixed to a portion of the upper side plate 11 cut into a rectangle. The seat bottom plate 12 is formed in a substantially rectangular shape, but the seat front plate 13 and the seat rear plate 14 are notched in a trapezoidal shape at the bottom center, and both ends of the notched portion are in contact with the outer surface of the side plate 11. It is arranged. The upper part of the seat front plate 13 is cut obliquely so that an infant can easily ride. The seat bottom plate 12, the seat front plate 13, and the seat rear plate 14 constitute a seat 10b for an infant to ride and have a function of interconnecting the left and right side plates 11, 11.

  A back plate 15 is disposed behind the seat 10b. The back plate 15 is mounted substantially horizontally on the upper portions of the side plates 11, 11, and its front end is fixed to the seat rear plate 14. Below the back plate 15, there is provided a substantially trapezoidal rear joint plate 18 having both ends connected to both side plates 11, 11 and connecting the left and right side plates 11, 11 inward. A guide groove 18 a that guides the swinging of the flange 21 is formed in the center of the left and right sides of the rear joint plate 18.

  The vertical plate 16 is sandwiched between the left and right side plates 11, 11 and the rear end thereof is fixed to the seat front plate 13. Below the vertical plate 16, as shown in FIG. 3, both ends are connected to the left and right side plates 11, 11, respectively, and a substantially trapezoidal front joining plate 17 that connects the side plates 11, 11 inward. Is provided. The front joining plate 17 is in contact with the lower edge of the vertical plate 16 and has a function of supporting the vertical plate 16.

  The side plate 11, the seat bottom plate 12, the seat front plate 13, the seat rear plate 14, the back plate 15, the vertical plate 16, the front joint plate 17, and the rear joint plate 18 are all flat wooden plates. The toy body 10 is formed by fastening and connecting them with a fastening material (not shown). The means for connecting these plate-like materials to each other is not necessarily limited to fastening, and for example, they can be connected by means such as fitting, screwing, and bonding, or can be connected using a fitting for connection. The material of the plate-like material is not necessarily limited to wood as long as it has an appropriate rigidity, and may be metal, alloy, synthetic resin, or other materials, but wood that is light and easy to process is most suitable. Moreover, the toy main body 10 should just be a shape which has the curved part 10a in a lower end, and is not necessarily restricted to connecting these plate-shaped materials. For example, the entire toy body 10 or a part of the toy body 10 may be synthetic resin-molded to form a wide curved portion 10 a extending to the left and right ends of the toy body 10.

  The wheels 20,... Are rotatably provided on the bending portion 10a. 1 and 2, each synthetic resin wheel 20 is pivotally supported by a metal wheel fixture 20a fixed to the side plate 11 at both front and rear ends, and is supported by the bending portion 10a. Is provided with a notch 11a that allows the wheel 20 to freely rotate. The means for attaching the wheel is not necessarily limited to this, and for example, the wheel is pivotally supported on a shaft protruding inward or outward from the lower end of the side plate 11 or is integrated with the two left and right wheels. Alternatively, both ends of the pivoting shaft may be pivotally supported on the left and right side plates 11 and 11 respectively. The material of the wheels 20,... Is not particularly limited as long as it is a rigid material, and is made of a metal material, an alloy material, a synthetic resin material, wood, or other material, but a synthetic resin material that can be easily molded is preferably used. . In order not to damage the floor surface or other indoor placement surface S, a rubber material can be attached to the outer periphery of the wheel 20.

  The wheels 20,... Are arranged in the front-rear direction on the curved portion 10a, and the left and right wheels 20, 20 provided at the same front-rear position form a pair. As shown by a solid line in FIG. 4, the toy body 10 is supported by the pair of wheels 20, 20 at the tail and the lower end of the basket 21 when it is tilted most backward. On the other hand, as shown by the phantom line in FIG. 4, when tilted the most forward, it is supported by the two pairs of wheels 20,. Therefore, at least two pairs of wheels 20,... Are necessary, and in order to obtain a sufficient propulsive force by allowing a large swing of the toy main body 10, at least three pairs centered around the front and rear of the curved portion 10a. It is preferable that wheels 20 are provided.

  The handle 24 is a substantially cylindrical member that is fitted into a through hole that penetrates the vertical plate 16 from side to side. In order to restrict the rotation of the handle 24 with respect to the through hole and to prevent the handle 24 from falling out of the through hole, a cylindrical tube 24a having both ends opened and a flange is provided around the handle 24. And is inserted into the through hole. A substantially cylindrical synthetic resin cap 24b whose one end is sealed is fitted to the left and right ends of the handle 24 so that the infant is not injured at the ridges. The shape and attachment means of the handle 24 are not limited to this as long as the handle 24 protruding left and right is fixed to the vertical plate 16. For example, the two handles 24, 24 manufactured separately from each other may be screwed or fixed to the left and right of the vertical plate 16. When an infant plays with the swinging propulsion toy 1, it sits so as to straddle the seat 10b and holds the handle 24 with both hands. Thereby, even if the swinging forward toy 1 of the present invention swings back and forth, the possibility of the infant falling is reduced.

  The flange 21 is formed by fitting a substantially cylindrical flange main body 21a on a swing shaft 21b formed by connecting two substantially cylindrical tubes in a substantially T shape. As shown in FIG. 5, a pair of left and right mounting brackets 21c, 21c formed in a substantially Ω-shaped cross section are provided with their upper and lower ends fixed to the rear upper end of the seat rear plate 14, By fitting the swing shaft 21b into the fitting portions 21d and 21d at the upper and lower approximate centers of the mounting brackets 21c and 21c, the flange 21 is pivotally supported so as to be swingable back and forth. The side plates 11 and 11 are partially cut away at the portion where the swing shaft 21b is disposed so as not to hinder the rotation of the swing shaft 21b. The means for pivotally supporting the upper end portion of the flange 21 is not necessarily limited to the above. For example, the flange 21 with the upper end portion perforated can freely swing on the pins connected to both side plates 11 and 11 at both ends. It may be fitted outside.

  Annular hooks 21e and 14a are respectively screwed and provided at the middle part of the heel body 21a and at the substantially right and left center of the lower end of the seat rear plate 14, and a spring 22 for urging the heel 21 forward is provided. These annular hooks 21e and 14a are provided with both ends locked. The flange 21 is swingable within the range guided by the guide groove 18a, and is disposed at a position that contacts the lower end of the guide groove 18a as long as an external force other than the urging force of the spring 22 is not applied. The spring 22 is not limited to the illustrated tension spring as long as it biases the flange 21 forward, and is not limited to the illustrated tension spring, for example, a torsion coil spring that connects the rear seat plate 14 and the flange body 21a, It may be a compression spring that connects the joining plate 18 and the flange main body 21a.

  The bag main body 21a extends rearward and downward from the portion fitted to the swing shaft 21b, and the lower end thereof is lower than the lower edge of the toy main body 10, and the swing propulsion toy 1 is placed thereon. Abuts on the mounting surface S. The lower end of the bag main body 21a is covered with a tubular rubber cover 23 whose one end is sealed. Since the lower end of the bag main body 21a covered with the cover 23 has a large frictional resistance and is difficult to slide on the placement surface S, the swinging propulsion toy 1 provided with the cover 23 can effectively obtain a propulsive force. Further, since the cover 23 has elasticity, it also has a function of protecting the floor surface and other indoor placement surfaces S so as not to be damaged. The material of the cover 23 is not particularly limited as long as it is rubber, and any rubber such as natural rubber and synthetic rubber can be used.

  The swing propulsion toy 1 of the present invention configured as described above is configured to move forward by swinging. First, an infant sits so as to straddle the seat 10b, gets on the swinging propulsion toy 1, and holds the handle 24 with both hands. Since the curved portion 10a is formed at the lower end of the toy main body 10, the swing propulsion toy 1 easily swings only by moving the center of gravity back and forth. When the infant moves the center of gravity rearward, the toe body 10 moves forward by rotating the wheels 20,. Thereafter, when the infant moves the center of gravity forward, the swinging propulsion toy 1 continues to advance by the rotation of the wheels 20,... And the rod 21 returns to the position where it contacts the lower end of the guide groove 18a. Therefore, the toy body 10 is swung only by the infant repeatedly moving the center of gravity in the front-rear direction, and the swinging propulsion toy 1 moves forward accordingly.

  The placement surface S using the swing propulsion toy 1 may be a hard surface that imparts a propulsive force by contact with the cover 23. By providing the cover 23, it is also possible to avoid damaging the indoor placement surface S such as the floor surface, so that the swing propulsion toy 1 can be used not only outdoors but also indoors.

  In the illustrated swing propulsion toy 1, the vertical plate 16 is formed to resemble the neck of a rabbit, and an attachment portion 21 f simulating the tail of a rabbit is attached to the heel body 21 a. . In this way, by imitating an animal or painting it, the swinging propulsion toy 1 becomes a more attractive toy that stimulates the playfulness of the infant. The animals imitated by the rocking propulsion toy 1 are not limited to rabbits, and may be terrestrial limbs such as horses, giraffes and elephants, and sea animals such as seals, sea lions and fur seals.
