  In the conventional infant seat device, when an infant with a small physique is on board, there is a limit to firmly fixing the body so that the infant does not move in the device. This is because when the body is strongly restrained by the seat belt, the infant refrains from being cramped and tries to move excessively. Therefore, as a matter of course, in order to prevent the infant from fluctuating from side to side or leaning forward, it is necessary to pay careful attention to driving without having to operate the sudden handle or the sudden brake.

  In the infant seat device described in Patent Document 2 or Patent Document 3, a handle dedicated to the infant (separate from the handle of the bicycle) is provided at the front center of the infant seated on the seat. However, the space between the front and rear of the infant-only handle and the seat is an open space that passes through in the left-right direction, and no structure is provided to close the open space. Needless to say, this open space is a space for the infant's legs to pass through. In fact, it is impossible for an infant to fall from this open space. However, there was one aspect that it was difficult for infants, bicycle drivers, and bystanders in the surrounding area to be relieved psychologically and visually due to the existence of this open space.

In particular, when a younger infant (such as an infant within 2 years of age) who is immature in physical strength or judgment is on board, the infant will be able to move both legs. As a result, it was necessary to keep the nerves sharp all the time, not only when riding a bicycle, but also when riding an infant.
On the other hand, in the infant seat apparatus described in Patent Document 1, as described above, the front of the infant seated on the seat portion is surrounded by the use of the forehead. However, the front wing has a structure in which a front wall portion is provided by separating a space for putting a load forward from the handle for the infant, so that the front of the infant is a wide open space. Therefore, there is still a problem that it is difficult to be relieved psychologically and visually.

  The present invention has been made in view of the above circumstances, and can be safely boarded even if it is an infant with a small physique, particularly an infant with a low age (for example, within 2 years of age). An object is to provide an infant seat device.

In order to achieve the above object, the present invention has taken the following measures.
That is, the seat device for infants according to the present invention includes a seat portion for sitting an infant, a backrest portion that rises at the rear portion of the seat portion, and forward from the left and right side portions of the backrest portion along the left and right side portions of the seat portion. It has a pair of left and right side guards that protrude, and a front guard part that is provided in an arrangement that blocks the front part of the infant seated on the seat part and prevents the infant from moving forward.

The front guard part includes a support column part that rises from the front part of the seat part to a height that exceeds the lower half of the infant seated on the seat part, and a left and right side guard part that is supported by the support part and that crosses between the left and right side guard parts. It is preferable to have a guard body formed in a length.
The front guard part is raised in such a manner that the support part is sandwiched between the crotch of the infant seated on the seat part, and the guard body protrudes right and left outward across the infant's leg relative to the support part. It is good also as what is formed in the front view T shape by being arranged, and the lower end part of the said support | pillar part is connected with the said seat part so that rocking | fluctuating back and forth is possible around a horizontal axis.

The front guard portion may be formed with a handle portion for an infant seated on the seat portion along an upper edge portion thereof.
The pair of left and right side guard parts are formed with a forward projecting dimension capable of completely blocking the infant's body from both the left and right sides when the infant seated on the seat part is leaning against the backrest part. Is preferable.

  In the infant seat apparatus according to the present invention, even if it is an infant with a small physique, especially an infant with a low age (for example, within two years of age), it can be safely boarded.

It is the side view shown in the state where the embodiment of the infant seat device concerning the present invention was attached to the bicycle.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 7 show an embodiment of an infant seat apparatus 1 according to the present invention. As shown in FIG. 7, the infant seat apparatus 1 according to the present embodiment is of a type that is mounted on the rear cargo bed 3 of the bicycle 2 (behind the saddle 4). In addition, the figure shows an object for a younger infant (such as an infant within 2 years of birth).

Hereinafter, for convenience of explanation, the lower part of FIG. 1 (plan view) is referred to as “front” of the infant seat apparatus 1, and the upper part of FIG. 1 is referred to as “rear” of the apparatus 1. Further, the right side of FIG. 1 is set as “left side” of the infant seat apparatus 1, and the left side of FIG. 1 is set as “right side” of the apparatus 1. The “front-rear and left-right” of the infant seat apparatus 1 is made to coincide with the direction viewed from the infant who has got on the infant seat apparatus 1.
As shown in FIGS. 1 to 6, the infant seat apparatus 1 is configured to support a toddler's back by standing at a rear portion of the seat portion 5 on which the infant is seated (supporting the buttocks of the infant) and the seat portion 5. A backrest portion 6 is provided, and the seat body 5 and the backrest portion 6 constitute an apparatus main body.

Further, the infant seat apparatus 1 is arranged so as to block the pair of left and right side guards 10 and 10 projecting forward from the left and right sides of the backrest 6 and the front of the infant seated on the seat 5 (FIG. 5 ( a) and a pair of left and right leg holders 12 and 12 which are arranged on the left and right sides at the front lower part of the seat portion 5.
First, the backrest 6 will be described. The backrest portion 6 is provided with a headrest portion 7 for supporting the infant's head from behind. The headrest portion 7 is provided so as to be slidable up and down as shown in FIG. 6, but even when arranged at the lowest position (see FIGS. 5A and 6A), the seat portion 5. It is arranged so as to be higher than the head of the infant sitting on the head. Needless to say, a height adjusting mechanism (see FIG. 4) between the backrest portion 6 and the headrest portion 7 for enabling the position fixing while the headrest portion 7 is moved to an arbitrary height position. Only the operation unit 8 is shown).

In this embodiment, the lower end portion of the headrest portion 7 is extended downward to the extent that it reaches the infant's back, so that it can be firmly supported from the infant's back to the head, and the operation is stable during vertical sliding. It is designed to have sex.
Next, the left and right side guard portions 10, 10 will be described. The side guard part 10 is provided on both the left and right sides of the backrest part 6 so as to cover the entire height range from the seat part 5 to the top of the backrest part 6 (headrest part 7). In order to allow the headrest portion 7 to slide up and down, the side guard portions 10 and 10 are divided vertically. That is, the upper half of the side guard part 10 is integrally formed with the headrest part 7, and the lower half of the side guard part 10 is on the backrest part 6 side (the base part holding the vertical slide of the headrest part 7) excluding the headrest part 7. On the other hand, it is integrally formed.

The left side guard portion 10 projects forward from the left side portion of the backrest portion 6 along the left side portion of the seat portion 5, and the right side guard portion 10 extends from the right side portion of the backrest portion 6 to the seat portion 5. It protrudes forward along the right side.
As shown in FIG. 5A, these side guard parts 10, 10 are arranged when the infant seated on the seat part 5 is leaning against the backrest part 6 (shoulder-arm-chest-abdomen). ~ All between the waist and hips) is formed with a forward projecting dimension that can be completely visually blocked from both the left and right sides. Here, “visual block” means a state of covering so that it cannot be seen from the side. In short, the side guard portions 10 and 10 are projected from the backrest portion 6 in such a size. It represents that.

In short, the infant is supported by the left and right side guards 10, 10 and the backrest portion 6 so as to be wrapped around.
In this embodiment, the extent over the infant's occipital region to the temporal region and further to the approximate rear half of the face is set as the forward overhanging dimension that can visually block both sides. However, completely blocking the right and left sight for infants not only gives a sense of blockiness and pressure, but also reduces the interest by not seeing the scenery, and also makes it impossible to consider the danger. There is also a risk.

Therefore, the vision to the left and right sides of the infant is not completely blocked. On the contrary, by curving the upper edge of the side guard 10 in a loose convex arc shape, the infant's face can be seen a little from the left and right sides. From this, it is said that the infant can enjoy the scenery on the left and right casually when the child faces sideways.
Moreover, the upper part of the outer side surface in the left side guard part 10 and the left leg holder part 12 mentioned later, and the upper part of the outer side surface in the right side guard part 10 and the right leg holder part 12 are the lower body guard part 13, 13 is formed continuously. The lower body guard portions 13 and 13 have a front projecting dimension that completely blocks the lower side of the infant seated on the seat portion 5 from the lateral direction (see FIG. 5A). Is formed.

  In addition, between the side guard part 10 and the lower body guard part 13, and between the lower body guard part 13 and the seat part 5 (the leg holder 12), there is not a physically clear separation. The area that visually blocks the infant's lower back. In the present embodiment, consideration is given to curbing the infant by placing the upper edge in a gentle concave arc shape.

Next, the front guard part 11 will be described. The front guard portion 11 is provided so as to cross the front of the seat portion 5 in the horizontal direction. The front guard portion 11 of the present embodiment includes a column portion 14 that rises to a height that exceeds the lower half of the infant seated on the seat portion 5, and a guard body 15 that is disposed at the upper end of the column portion 14.
The support column 14 is disposed so as to be sandwiched between the groins of the infant seated on the seat portion 5, and the lower end portion thereof is connected to the seat portion 5 so as to be swingable back and forth around the horizontal axis. In the present embodiment, a support base 20 that protrudes upward from the central portion of the front end of the seat portion 5 is provided, and a horizontal shaft support portion 21 (see FIG. 6) is formed on the front surface of the support base 20. .

  On the other hand, the guard body 15 protrudes outward in the left-right direction from the support column 14, crosses over the leg of the infant seated on the seat 5, and the left and right ends thereof are the front portions of the side guard 10. It is bent so that it faces (backward). That is, the guard body 15 is formed to have a left and right length that extends between the left and right side guard portions 10. Note that whether the left and right end portions of the guard body 15 are in contact with the side guard portion 10 is not particularly limited. In the present embodiment, the left and right end portions of the guard body 15 and the side guard portion 10 are held in a non-contact manner.

  Thus, the front guard portion 11 having the guard body 15 protruding left and right at the upper part of the support column portion 14 has a T shape when viewed from the front. Therefore, this front guard part 11 has the effect | action for preventing the movement so that the infant seated on the seat part 5 may not move forward (a deliberate operation | movement or the front turning by a sudden stop of a bicycle). It also has the effect of inhibiting the infant from flapping his legs unnecessarily.

As described above, the front guard portion 11 can swing back and forth with the lower end portion of the support column portion 14 as a fulcrum. Therefore, when the infant is placed on the seat portion 5 and lowered, the front guard portion 11 is moved forward. It is only necessary to open the upper part of the seat part 5 by being tilted, and after the infant is placed, the front guard part 11 may be raised rearward to make it stand up.
Needless to say, a stopper mechanism (see FIGS. 2 and 3) for holding the standing state of the front guard portion 11 between the seat portion 5 (support base 20) and the front guard portion 11 (post portion 14). Only the operation unit 22 is shown).

The front guard portion 11 is formed with a handle portion 25 dedicated to an infant along the upper edge portion thereof.
Next, the left and right leg holders 12, 12 will be described. As described above, the leg holders 12 are arranged on the left and right sides at the lower front part of the seat part 5. Therefore, these leg holders 12 can accommodate the legs that the infant sitting on the seat 5 hangs downward from the seat 5.

The leg holder 12 has a front surface 12a, a rear surface 12b, a left and right inner side surface 12c, and a left and right outer side surface 12d so as to surround the front and rear left and right sides of the accommodated infant's leg. Is formed. Moreover, it has the bottom face 12e which closes the lower end of this cylinder shape, and is formed in the cup shape.
In the leg insertion portion 12, a vent hole penetrating in the front-rear direction is formed in the front surface 12a, and a through hole penetrating in the vertical direction is formed in the bottom surface 12e. These through holes provide good ventilation and prevent the infant's legs from steaming. In addition, the through hole in the bottom surface 12e can provide raindrop drainage during rainy weather, so that rainwater does not collect while the bicycle 2 is parked.

Since the leg holder 12 having such a configuration is cylindrical, not only a high defense effect against impact and contact is obtained, but also various effects such as cold protection, wind protection, drip-proof, insect repellent and the like. Is obtained. It also has the effect of preventing dogs and the like from jumping towards the infant's legs.
As is clear from the above detailed description, in the infant seat apparatus 1 according to the present invention, the seat 5
The front guard 11 is set so as to cross the front face of the infant while the infant is seated on the front. In other words, since there is no open space in front of the infant, it can be reassured psychologically and visually not only for the infant but also for the driver of the bicycle 2 and the surrounding bystanders. Also, even if the infant actually moves the heel forward or flapping both legs, it is safe because it never gets over the front guard 11 and jumps forward.

Therefore, even if it is an infant with a small physique, especially a young child (for example, within two years of age), it can be safely boarded.
By the way, this invention is not limited to the said embodiment, It can change suitably according to embodiment.
For example, the EVA resin (ethylene vinyl acetate co-polymerized) is provided for each part or all over the top surface of the seat portion 5, the front surface of the backrest portion 6, the inner surface in the left-right direction of the side guard portion 10, the rear surface of the front guard portion 11, and the like. It is preferable to paste a highly cushioning interior material formed of a polymer) or the like.

A through-hole penetrating in the left-right direction with respect to the side guard portion 10, a through-hole penetrating in the front-rear direction with respect to the backrest portion 6, or a through-hole penetrating in the vertical direction with respect to the seat portion 5 It is good to form.
The front guard portion 11 may include a pair of left and right support columns 14 and 14 that stand up on the left and right sides of the seat portion 5 (on both sides of the infant). Further, the guard body 15 may have a shape in which the plan view is curved in a semicircular shape or a shape in which a corner is bent at a sharp angle.

The front guard unit 11 may be configured to cope with the child's getting on and off, such as an upward flip-up type or a double door spread type.
The leg holder 12 may have a rectangular tube shape, a cylindrical shape, or a boot shape. In the case of the cylindrical shape, the front 12a, the rear 12b, the left and right inner surface 12c, and the left and right outer surface 12d are ambiguous. Keep things. The leg holder 12 may have a structure that is detachable from the seat 5. By doing in this way, according to an infant's physique and age, it becomes possible to use a right-and-left open type step properly.

Various seat belts such as a 2-point system, 3-point system, 4-point system, and 5-point system may be attached.
