Therefore, once the swinging member 62 is shaken, the swinging member 62 is periodically shaked to the both sides by the center of the width direction of the seat body 30 shown in FIGS. 4 and 5 due to gravity. As shown in FIG. 6, the rocker 62-rock, the position of the front end 62a of the rocker 62 moves inward in the width direction of the seat body 30. However, the receiving table 52 of the movable portion M of 19 200534814 疋 'must slide relative to the front end portion of the swinging member 62 in the long direction of the swinging member 62. In addition, the movable member is restricted from moving in the width direction of the seat body 3G by the fixed portion ㈣ restricting element 43. For these reasons, as shown by the dotted line in FIG. 6, even if the position of the front end of the shaker post moves in the width direction of the body 30, the receiving table η will not move in the width direction of the seat body 30 . With this, movable: 51 not

It reads the width M axis in the seat, and can move back and forth smoothly and periodically only after touching the body 30. Furthermore, the rocker 62 periodically shakes the mouth based on the so-called horizontal pendulum principle. This not only lengthens the length of the rocker 62 in the long direction, but also allows the vertical direction of the rocker shaft 61 to move toward the seat body 30. The smaller the inclination angle Θ in the width direction is, the longer the swing period of the swing member ⑽ becomes. In addition, the tilt angle Θ-of the tilt 61 of the shaft 61 becomes smaller, and the thickness of the swing mechanism 40 becomes thinner. This can be adjusted to the most appropriate shaking cycle for infants 15 without increasing the overall size of the crib 1. Furthermore, the restricting element 43 has a restricting shaft 43a for guiding through the guide plate 53. Therefore, even if the movable portion 51 is reciprocated relative to the fixed portion 41 ', the movable portion 51 can be prevented from falling off from the fixed portion. As described above, according to this embodiment, when the baby shaker 1 is used as a chair or the baby shaker 1 is used as a chair, an infant can sit on the baby shaker 1 to eat or read. When the baby bed 1 is used as a bed, σ is lying on the baby bed 1 for diaper changing or care after bathing, or sleeping in the baby bed 1 in the morning. The rocking mechanism 62 supported by the fixed portion 4 i of the rocking mechanism 40 can be periodically rocked by the principle of a horizontal single pendulum. 20 200534814 The receiving table 52 of the movable portion 51 is slidably supported by the front end portion 62 a of the rocker 62. Furthermore, the restricting member 43 of the fixed portion restricts the movement of the movable portion 51 toward the width% of the seat body. By this means, the movable member 62 can be moved by gravity to move the movable relative positioning portion 41 smoothly and periodically in a forward-backward direction touching the main body. Furthermore, this rocking mechanism 40 has a thin, flat outer shape. Therefore, _ the swing mechanism 40 can be arranged below the seat body 30, and thereby the size of the entire baby bed 1 can be reduced. Article 10 15 20 The reciprocating period of J mi can be extended not only by making the length of the swing member 62 in the long direction longer, but also by making the swing axis ㈣ = Γ direction? Oblique angle, small and long. In addition, the swing _ 1 and Θ are small, so that the thickness of the swing mechanism 40 can be further restricted. Therefore, it is expected that the baby will find a bed 丨 the whole wealth will increase, and adjust the financial cycle of the seat body 30 to the most appropriate cycle for young children. It also applies a restriction element φ — 53 that is held by the sides in the original position: 3 7 extends upward and faces _ towards the width direction of the seat body 30. It is set to hold the guide bow. 51 cases, but not limited to this. The guide is held by the guide plate 53 from both sides (not shown in the figure), and the roll 2 of the moon seat 2 in the width direction 51 is opposite to the fixed portion or, as shown in Figure 7 Shown in -guide_, Shixin :: == Restriction roller 65 in the guide plate guide groove 64 / Arranged in the wrong way to make the guide groove 64 and the restriction roller 21 65 200534814 bayonet / also Movement of the movable portion M with respect to the fixed portion W in the width direction of the seat body is restricted. In the modification of FIG. 7, the front end portion 62 a of the rocker 62 is provided at the receiving base 52, and the front end portion 62 of the rocker 62 is held and extended in the front-rear direction of the seat body 30. Yes-for extensions 52b, 52b. Then, a restriction shaft 52c is disposed between the extension portion 52b and Xun so as to penetrate the guide opening 62o. Then, the guide opening arranged in this way must be bound to the restricting shaft 52c, and the movable portion 51 can be prevented from "detaching" from the fixed portion. The second embodiment is below 10, and the eighth and ninth figures will be used to describe the first embodiment of the present invention. Embodiment 2. The second embodiment shown in Figs. 8 and 9 differs only in the swing mechanism 其他, and the others are approximately the same as the J-th embodiment shown in Figs. 1 to 7. Therefore, the rest of the swing mechanism is omitted. Detailed descriptions of the parts are given in FIG. 8 and FIG. 9, and the same reference numerals are given to the same parts including the swing mechanism as in the first embodiment of FIG. 15 to FIG. 7 and the detailed description is omitted. Explanation ... Further, Fig. 8 is a side view of the swing mechanism 70, and Fig. 9 is a front view of the swing mechanism 70. As shown in Figs. 8 and 9, the swing mechanism 70 includes: a fixing portion 41; The fan-shaped roller 71 is provided on the fixed portion 41. The fan-shaped roller 71 is formed by a slightly fan-shaped column having at least an arc portion 71a in section and the arc portion 7U faces the fixed portion 41; and the movable portion 51 is used for The support body 73 is rotatably penetrated through the fan roller 7m, and the seat body 3 is supported from below. This swing mechanism 70 can rotate the fan-shaped roller 71 on the fixed portion 41 22 200534814 and the second moving portion 51 can move relative to the fixed portion 41 in the forward and backward directions of the seat body milk, thereby 'may The seat body% supported by the movable portion 51 is reciprocated in the front-rear direction of the baby bed 1 with respect to the side plate 20. The front-rear direction of the so-called seat body 30 is the paper surface of 5 on the side view in FIG. In the left-right direction, the so-called width direction of the seat body 30 is a direction perpendicular to the paper surface in the side view of FIG. 8.

10. The fan-shaped roller 71 in this embodiment is formed by a fan-shaped column whose bottom surface 71b is fan-shaped. The fixing portion 41 is formed in a flat plate shape in the present embodiment. A pair of fan-shaped rollers 71 and 71 spaced along the width direction are provided on the upper surface 41a of the fixing portion 41. The pair of fan-shaped rollers 71 and 71 are arranged along the front and rear. There are two sets of directional intervals (ie, a total of four rotating rollers). The sector rollers 71 spaced in the width direction are overlapped when viewed from the side as shown in FIG. 8, and the sector rollers 71 spaced in the front and rear direction are overlapped when viewed from the front as shown in FIG. 9. As described above, this fan-shaped roller 71 has its arc-shaped portion 71 a facing the upper surface 41 a of the fixed portion 41. Therefore, the sector roller 71 and the fixed portion 41 are in line contact along the contact line L2 (28 and 9). Hereinafter, the support shaft 73 will be described in more detail. As shown in Figs. 8 and 9, the two support shafts 73 and 73 extend in the width direction of the seat body 30. Each support shaft 20 passes through a pair of fan-shaped rollers 71 and 71 arranged at intervals in the width direction from the apex 71c of the fan-shaped bottom surface 71b of the fan-shaped roller 71 and runs on the symmetric line L1 of the fan-shaped bottom surface 71b. A bearing (not shown) is provided between the support shaft 73 and the sector roller 71, and the sector roller 71 can be smoothly rotated around the support shaft 73 as a center. The movable portion 51 holds the vicinity of the rain end portions of the two support shafts 73 and 73 through four receiving tables 72 provided under the flat-shaped movable portion base 5la. Therefore, by rotating the sector roller 71 on the fixed portion 41, the movable portion 51 can move in the front-rear direction with respect to the fixed portion 41. Further, as shown in Fig. 9, guide plates 53, 53 are provided on the upper surface 41a of the fixed portion 41, respectively, near the inner sides in the width direction of the respective sector rollers 71. As shown in FIGS. 8 and 9, the guide plate 53 is perpendicular to the fixing portion 41 and extends in the front-rear direction of the seat body 30. The guide plate 53 is provided with a guide opening 53a for engaging the support shafts 73 with each other. The guide opening 53a is penetrated by the support shaft 73 and is formed in a shape along the 10-track of the support shaft 73 when the sector roller 71 rotates on the fixed portion 41. This rocking mechanism 70 has a thin, flat outer shape as shown in Figs. 8 and 9. Therefore, the swing mechanism 70 can be arranged below the seat body 30, and the entire baby bed 1 can be miniaturized. The operation of this embodiment of this structure will be described below. 15 20 The fan-shaped roller Ή is composed of a fan-shaped column whose bottom surface 71b is fan-shaped as described above, and its heavy symmetrical line L1Jl. χ, a support shaft 73 for receiving the weight of the seat body 30 and the movable portion 51 passes through the line of symmetry 0 of the sector roller 71. Therefore, as shown by the solid line in FIG. 8, the fan-shaped roller is called the symmetry line U and the fan-shaped 71 is intersected with 卩 4_touch Zhuang 2 and the shape 71 is shown toward the imaginary line in FIG. 8, ... ⑽ The weight of the fan-shaped second child 7 on the line of symmetry L1 of Shishi Zhuan: and 仏 73 will be opposite ^

The contact line L2 rotates on the fixed part 41 according to the secret side J 疋 I, ^, ^ 7 / this,-once the fan roller 71 9H ^.. _ Feather 1 will be moved by the 8th and the 8th figures due to gravity. The line of symmetry L1 is perpendicular to the center of the fixed part and is centered toward 24 200534814

Both sides rotate periodically. With the periodic rotation of the sector roller 71, the movable portion 51 can reciprocate relative to the fixed portion 41. The periodic movement of the sector roller 71 is based on the principle of a so-called rotating single pendulum. Therefore, the period of the reciprocating movement of the movable portion 51 can be changed by changing the shape of the M-shaped roller 71_, especially the shape of the arc-shaped portion 71a, or by displacing the through position of the support shaft 73 from the line of symmetry. Thereby, the seat body 3 can be reciprocated _ week _ to the most appropriate swing period for the child. 10 15

20 Furthermore, a guide plate 53 is divided in the width direction of the seat body 30 on the inner side of each of the sector rollers 71, and the support shaft 73 penetrates the guide opening 53a of the guide plate M, so that not only the sector rollers can be prevented. The chair body can be moved in the width direction, and the movable portion 51 can be prevented from being detached from the fixed portion 41. In addition, the fan roller 71 can be prevented from being excessively rotated. Thereby, "the movable portion 51 cannot be moved in the width direction of the seat body 30" and can be smoothly reciprocated only in the front-rear direction. As described above, according to the present invention, the principle of the sector roller provided on the fixed roller is rotated periodically. The fan-shaped borrower guide 53 can restrict the movement in the width direction of the seat frame. ^ The shuttlecock 71 is rotatably penetrated and held in the movable portion ", and is guided by the two-lead guide plate 53 of the supporting shaft. Therefore, by turning on the fixed portion 41, the weight W1 can be used to change it ^ 51. The front and rear directions of the main body 30 of the fixed part are smoothly and periodically reciprocated by changing the shape of the fan-shaped roller 71, and the special movement is made. The penetration position of 73 is sacrificed by the fun of the displacement of the grass on the line of symmetry L1. With this, the shape of 25 200534814 of the exhausting swing mechanism becomes larger, and the reciprocating movement of the seat body 30 is adjusted to the swing period suitable for the infant. Furthermore, the swing mechanism 70 has a thin and flat outer shape. Therefore, the swing mechanism 70 can be disposed below the seat body 30, and the baby shaker 8.5 can be miniaturized. Furthermore, this embodiment is shown in An example in which a pair of fan-shaped rollers 71 spaced apart from each other along the width direction of the seat body 30 on the fixing portion 41 is used as the width

When the seat body 30 is reciprocated, Rotate 90 ° by the push-and-push mechanism such as the torsion bar 98a protruding toward the rear side in the front-rear direction, and the lock element 99 is swung upward by the lock (%). As a result, the wheel shaft enters the lock element. In the locking groove 99a of 99, the wheel shaft 97 is restricted from moving in the front-back direction of the seat body 30, and the seat body 30 is fixed relative to the side plate 20. As described above, according to this embodiment, the It is bundled on the bending path 93 of the fixing part 41. Therefore, the movable portion 51; borrow; = 5 moves back and forth relative to the fixed portion 41. The swing mechanism 90 has a thin, flat outer band. The swing mechanism 90 can be arranged below the seat body 30, and the baby bed can be made compact overall. Furthermore, by changing the shape of the curved rail 93, the reciprocating period of the movable portion 51 can be made longer without increasing the shape of the swing mechanism 90. Thereby, the reciprocating movement of the seat body 30 can be adjusted to the swing period most desirable for a child. $ »

Furthermore, by using the end portion 97 of the wheel shaft 97 & the guide bow I opening 94 engaged with the side wall%, the movable portion 51 can be prevented from "detaching from the fixed portion and the movable portion μ is relatively opposed to the fixed portion 41." The wheel 96 has a flange portion 卡 engaged with the inner side in the width direction and the side surface 93c of the inner 10 side of the curved channel 93, and cannot move in the direction of visibility with respect to the wheel shaft. The side wall 91 is provided to cover Bend the top 91a above the guideway%. As a result, the movement of the movable portion 51 in the width direction of the seat body 30 can be restricted, and the movable portion 51 can smoothly move back and forth in the forward and backward directions of the seat body 30. 15 Further By rotating the lock shaft 98, 9% of the locking grooves of the lock element 99 are clamped to the wheel shaft 97 in the rear direction by φ, and the movement of the movable portion 51 in the front-rear direction is restricted. With this, the seat body 3 can be moved. It is fixed to the side plate 20. Furthermore, in this embodiment, it is shown that the fixing portion 41 has a lock shaft 卯 that extends in the front-rear direction of the seat body 30 and is rotatable, and is fixed to the lock shaft 2098, and is disposed at The wheel shaft 97 of the wheel 96 is below the wheel shaft 97 An example in which the locking elements 99, χ of the engaged locking grooves 99a can restrict the private movement of the wheel shaft 97 in the front-rear direction of the seat body 30 by turning the lock shaft rotation lock element 99, but it is not limited thereto As shown in FIG. 15A and FIG. 15B, the fixing portion 41 may include the following members, namely, the lock shaft 102, which extends from the seat 36 200534814 to the front-rear direction of the body 30 and can move in the front-rear direction The lock element 99 is a lockable groove 99a that can be moved in the up-down direction and is disposed below the wheel shaft 97 of the wheel 96 and is used to engage with the wheel shaft 97.
