Description

[Detailed Description of the Invention] Field of the Invention This invention relates to a pair of armrests located on both sides of the seat portion of a child care appliance with a seat, such as a baby carriage, and in particular, it relates to an improvement in the shape of such armrests. It is related to.

Background of the invention In addition to the above-mentioned baby carriage, childcare equipment with a seat to which this invention is applied include childcare chairs and Haiti Air.

The armrest provided in the child care appliance with a seat serves as a protective frame for the seated infant from the side, and also functions as a stand on which the infant's hands and elbows are placed.

By the way, regarding such childcare equipment with a seat, a preferred form of the seat focused on preventing dislocation of the hip joints of infants is disclosed in Japanese Patent Application No. 1983-61813 filed by the applicant of the present utility model registration. In this application, the seat portion of the seat is dimensioned such that the groin distance is maintained at a predetermined value to prevent hip dislocation, and there are no obstacles that press inward on the outside of the kneecaps of a sitting infant. Such a seat is disclosed, which is provided with a pair of positioning members arranged within a permissive space and for lateral positioning of the buttocks of an infant placed on the seat.
The pair of positioning members are positioned, for example, on both sides of the rear end of the seat so as to sandwich the infant's buttocks from both sides.

From the viewpoint of preventing dislocation of the hip joint as described above, each rear end of the pair of armrests also acts as the pair of positioning members described above. However, if such a pair of positioning members are provided on the seat, there is no need for the armrest to have such a function. If the rear width of the armrest is narrowed in order to provide such a function, it will actually hinder the movement of the infant, which is not desirable. On the other hand, simply widening the distance between a pair of armrests would make the width dimension of the childcare equipment with a seat too large, making it unsuitable for a baby carriage that requires portability, for example. Not desirable.

Purpose of the invention Therefore, the purpose of this invention is to provide an armrest for a child care appliance with a seat that does not hinder the movement of an infant sitting on the seat and provides a better environment for the infant without giving the infant a feeling of restraint. That's true.

Summary of the invention The armrest of this invention is characterized in that a recess is formed on the inner surface at the position where the infant's torso rests.

Effects of the invention According to this invention, the distance between the armrests is widened only in the area where the infant's torso rests, so it does not impede the movement of the sitting infant, does not give the infant a feeling of restraint, and provides a better environment. At the same time, the width dimension of the childcare equipment with a seat is not increased.

DESCRIPTION OF EMBODIMENTS FIG. 1 is a perspective view of a baby carriage to which an embodiment of this invention is applied. This drawing shows a seat 1, a backrest 2, a pair of armrests 3, and a torso guard 4 as members constituting the seat of the baby carriage.

A pair of armrests 3 are connected to the seat 1 and the backrest 2.
located on both sides of the space defined by The torso guard 4 is attached to connect the front ends of the pair of armrests 3 to each other.

In FIG. 2 the armrest 3 is shown in side view and the third
The figure shows a part of the seat including the armrest 3 in plan view.

In particular, as is clear from FIGS. 1 and 3, a recess 5 is formed on the inner surface of the armrest 3. The position where this recessed portion 5 is provided corresponds to the position where the torso of a seated infant hits. Due to the presence of this recess 5, the distance between the pair of armrests 3 is widened in this portion.
Therefore, a seated infant will have a relatively wide range of tolerance for its movements.

It should also be noted that even with the formation of such a recess 5, the effective portion of the armrest 3 provided on the upper surface of the armrest 3 is not so narrowed. That is, when observing the posture of a seated infant, it is not always the case that the infant is in a state of leaning against the backrest 2, but rather, the infant often takes a vertical or slouched posture while resting his or her arms on the armrest. In particular, when the torso guard 4 is provided, the torso guard 4 and the front part of the armrest 3 are the positions where the infant's hands and elbows are placed. Therefore, as clearly seen in FIG. 3, the front portion of the armrest 3 maintains a relatively large area, and the original function of the armrest is not hindered in any way.

In particular, in the illustrated embodiment, each armrest 3 has a trapezoidal shape that widens forward. This means that
This allows the above-mentioned armrest to perform its original function in a more favorable manner.

Although the above description has been made in relation to the illustrated embodiment, the shape of the recess 5 provided in the armrest 3 is not limited to the illustrated shape. In the illustrated embodiment, the recess 5 is hollowed out in an arc shape, but the recess 5 may be hollowed out in a trapezoidal shape or the like.

Further, although the above-mentioned embodiments have been described in relation to a baby carriage, this invention can be applied to all other child care appliances with seats, including child care chairs, Haiti Air, and the like.
