つて木馬を前後に揺動させることができるのは、
周知のとおりである。 For example, a toy horse for young children that has a circular arc surface of a constant curvature in contact with the floor is commonly used. When you ride this and move your center of gravity back and forth by leaning your body, you can swing the rocking horse back and forth by the action of the circular arc surface.
As is well known.
この考案は、前後に揺動させることによつて前

This was done with the aim of significantly improving the playability and maneuverability of toys such as rocking horses for infants.
以下、この考案の実施例を図面について説明す

る。 The drawings show the principle of the swinging advance mechanism according to this invention. The swinging advance mechanism basically consists of a pair of fan-shaped members 2a, 2b having circular arc surfaces 1a, 1b of substantially the same curvature. A pair of fan-shaped members 2a, 2
b are arranged concentrically with each other and connected by a common support shaft 3 so as to be relatively rotatable. In this embodiment, the support shaft 3 is arranged on the central axis of each fan-shaped member 2a, 2b. Also, one fan-shaped member 2
A weight W is provided to apply an unbalanced load to a. The weight W functions to rotate one fan-shaped member 2a in one direction around the support shaft 3 relative to the other fan-shaped member 2a, as will be described later.

支持される。 In the swing forward mechanism configured as described above, as shown in FIG. 1, when the pair of fan-shaped members 2a and 2b are partially overlapped,
Each circular arc surface 1 in the overlapped area A
a, 1b can be brought into contact with the floor surface 4, respectively. At this time, the frictional resistance between each arcuate surface 1a, 1b and the floor surface 4 prevents each fan-shaped member 2a, 2b from rotating relative to each other around the support shaft 3, and maintains the size of the overlapping area A. do. Therefore, the pair of fan-shaped members 2a, 2b can be stood at the predetermined position P1 and kept stationary. The entire load is supported by the floor surface 4 via each circular arc surface 1a, 1b.
次いで、第２図に示されているように、扇形部
材２ａ，２ｂを後方に揺動させると、一方の扇形
部材２ａの円孤面１ａは床面４から離れる。この

向に回動する。このため、第３図に示されている
ように、扇形部分２ａ，２ｂがオーバーラツプし
た領域Ａは減少する。 Next, as shown in FIG. 2, when the fan-shaped members 2a and 2b are swung backward, the circular arc surface 1a of one of the fan-shaped members 2a is separated from the floor surface 4. At this time, only the circular arc surface 1b of the other fan-shaped member 2b contacts the floor surface 4, and the entire load is supported by the floor surface 4 via this circular arc surface 1b. Therefore, the frictional resistance between the circular arc surface 1a and the floor surface 4 is removed, and one fan-shaped member 2a rotates clockwise around the support shaft 3 relative to the other fan-shaped member 2b due to the action of the weight W. Rotate to. Therefore, as shown in FIG. 3, the area A where the fan-shaped portions 2a and 2b overlap decreases.
その後、第４図に示されているように、扇形部

域Ａは、増大し、もとの大きさになる。 Thereafter, as shown in FIG. 4, when the fan-shaped members 2a and 2b are reversely swung forward, the circular arc surface 1a of one of the fan-shaped members 2a is moved to a position in front of the original position P1 . It contacts the floor surface 4 at P 2 .
The distance l between the positions P 1 and P 2 is such that while the arc surface 1a is apart from the floor surface 4 and only the arc surface 1b is in contact with the floor surface 4, the sector-shaped member 2a is relative to the sector-shaped member 2b. This corresponds to the relative rotation angle, ie, the amount by which the overlap area A is reduced. As shown in FIG. 5, when the fan-shaped members 2a and 2b are further swung, the circular arc surface 1b of the other fan-shaped member 2b separates from the floor surface 4. At this time, only the circular arc surface 1a of one fan-shaped member 2a contacts the floor surface 4,
The entire load is supported by the floor surface 4 via the circular arc surface 1a. Therefore, the frictional resistance between the circular arc surface 1b and the floor surface 4 is removed, and the fan-shaped member 2b rotates clockwise around the support shaft 3 relative to the fan-shaped member 2a. The area A where the sectors 2a and 2b overlap increases and returns to its original size.
扇形部材２ａ，２ｂを再たび後方に揺動させる

１ａ，１ｂがそれぞれ床面４に接触し、第１図の
もとの状態に復元する。しかしながら、このとき
は各円孤面１ａ，１ｂは位置P1ではなく、位置
P2において床面４に接触する。したがつて、全
体が距離ｌだけ前進している。 When the fan-shaped members 2a, 2b are swung backwards again, the circular arc surfaces 1a, 1b respectively contact the floor surface 4 in the overlapping area A, restoring the original state shown in FIG. However, in this case, each circular arc surface 1a, 1b is not at position P 1 , but at position
It contacts the floor surface 4 at P 2 . Therefore, the whole is moving forward by a distance l.
したがつて、扇形部材２ａ，２ｂを前後に揺動
させることによつて距離ｌづつ間欠的に前進させ
ることができるものである。 Therefore, by swinging the fan-shaped members 2a, 2b back and forth, it is possible to move the fan-shaped members 2a, 2b forward intermittently by a distance l.

る。 As is clear from the above examples, this invention has the following features:
A common support shaft 3 is arranged on the central axis of the pair of fan-shaped members 2a, 2b, and the support shaft 3 allows each sector-shaped member 2a,
Connect 2b. Since the weight W is provided on one of the fan-shaped members 2a, an unbalanced load is applied to the one of the fan-shaped members 2a, and the one of the fan-shaped members 2a is rotated around the support shaft 3, each of the fan-shaped members 2a, 2
Overlapping a part of b, each arc surface 1
When a and 1b are brought into contact with the floor surface 4 and swung back and forth, each of the aforementioned members 2a and 2b rotates relative to each other around the support shaft 3, making it possible for the whole to move forward intermittently. can. Moreover, the support shaft 3 is connected to each fan-shaped member 2.
a, 2b, and even if the sector-shaped members 2a, 2b rotate relative to each other, the sector-shaped members 2a, 2b are always held concentrically, regardless of the relative rotation of the sector-shaped members 2a, 2b, and their circular arc surfaces 1a , 1b are held on the same curved surface. Therefore, when the whole body is swung back and forth and moved forward intermittently, the position of the support shaft 3 is always maintained at the same height and does not fluctuate up and down. Therefore,
The whole can be smoothly swung and moved forward.
