Description

[Detailed Description of the Invention] Field of the Invention The present invention relates to a baby carriage bed, and in particular, the part of the baby carriage on which an infant is placed basically takes the form of a bed, and incidentally also takes the form of a chair. J: This relates to a baby carriage bed that can be transformed into a sea urchin.

Description of Prior Art Baby carriage, at least that's 1! ! ! In its early days, it was a so-called ``box type,'' in which infants were placed comfortably in a baby carriage while lying down.

Therefore, it is favorable for infants' development.
It was also excellent in livability. However, as the times have changed, this view of placing importance on the position of infants has gradually faded, and more emphasis has been placed on convenience as a means of transporting infants. For example, the majority of baby carriages are chair-shaped, and moreover, because of the need to use public transport, foldable baby carriages have become popular.
What's more, the smaller ones are becoming more popular. This was an inevitable result of various changes in lifestyles, and was also a requirement of the times.

As mentioned above, it cannot be denied that pursuing convenience as a means of transporting infants is an important point in the development of baby carriages. However, it seems necessary to go back to the basics and reconsider the structure of a baby carriage that does not impair the growth or comfort of infants and is convenient to use.

OBJECTS OF THE INVENTION As mentioned above, an object of the present invention is to provide a bed for infants that does not impair the growth or comfort of infants. According to this invention, the bed can also be transformed into a chair shape for convenient use.

Contents of the invention This invention is a so-called "box type"2)
This is a bed for a baby carriage, and is basically an integral box-shaped bed that has a bottom wall, a front wall, a back wall, a left side wall, and a right side wall. When the front wall of such a box-shaped bed is removed and the front is opened, it becomes chair-like. As a configuration for that, the left and right sides i? A pair of lower frames supporting each front part of the 1iffl from below extends along the lower sides of each front part of the left and right side walls, and the rear ends of the lower frames are rotatably supported by an axis pointing in the left-right direction. . A bend is formed along the boundary line between the front and rear parts of the bottom wall. Further, each front portion and each rear portion of the left and right side walls are configured to be separable from each other, and are connected by a distinguishable joining means such as a fastener. In such a configuration, when the lower frame is rotated downward with the front and rear portions of the left and right side walls separated, the front wall is displaced downward, and the bottom wall is The front part is folded against the rear part along the bending line, thereby opening the front part and allowing use as a chair. When it is shaped like a bed, it is sufficient that the lower frame is kept in a horizontal position, and the means for maintaining this horizontal position is achieved, for example, by a tension link connected to the main body of the stroller. be done.

Effects of the Invention According to the present invention, a stroller bed that has an integral box shape as a whole can be reclined, which is preferable in terms of growth and livability of infants. In order to transform this basic bed-like form into a chair-like one, it is necessary to add new parts prepared separately or to separate and remove parts that were originally part of the bed. There is no need to change the shape of the bed, so all you have to do is deform some of the parts of the bed while still being connected to other parts. In other words, each front part and each rear part of the right side wall are separated, and by simply rotating the lower frame downward, the part held by this lower frame will move downward accordingly. The front of the bed is opened so that it can be moved and used as a chair. Therefore, there is no risk of parts being lost, which is common in cases where components that can be separated and removed are provided.

DESCRIPTION OF THE EMBODIMENTS FIG. 1 is a right side view of a baby carriage equipped with an embodiment of the present invention, and the bed is in the original bed shape. FIG. 2 is a perspective view showing only the bed shown in FIG. 1. Third

In the illustrated embodiment, a fastener 27 is provided along this border line.

In the state shown in FIGS. 1 and 2, the bed 1 is in its original bed shape. In this state J3, the tension link 15 supports the lower U frame 12 with respect to the front leg 16, and maintains the lower frame 12 in a horizontal position. In the bottom wall 2, is it a stand core? ,! 8.9゜10zu, previous part 2a
The rear portion 2b has a substantially uniform horizontal surface.

In order to transform the bed 1 from the above-described bed shape to a chair shape, first, the fasteners 14 fJZ Un are released.

Then, the engagement pin 19 is removed from the engagement recess 18 of the tension link 15. According to this, bottom frame 1
2 is in a state where it can be rotated downward I\ around 113. In accordance with this upward rotation, the front wall 3 is displaced downward l\, and the front parts 5a, 5a of the left side wall 5 and right side wall 6 are also displaced downward, and in the bottom wall 2, It is bent along a bending line formed between the front part 2a and the rear part 2b. Finally, the lower frame 12 rotates downward to the state shown in FIG.

The end of the downward rotation of the lower frame 12 does not have to be in the state shown in FIG. 3, and may be rotated further downward.

On the other hand, in the rear part of the bed 1, the reclining adjustment link 25 is operated to raise the main lever 21. As a result, the bed contact portion support member 23
is displaced upward, the rear wall 4 is lifted, and the bottom surface! ! ! The portion loaded with the rear half core material 10 of the rear portion 2b of No. 2 is lifted. A backrest portion is formed by this rear half core material 10 and the back wall 4.

The auxiliary lever 22 controls the posture of the bed rear support member 23. For example, in the state shown in FIG. Adjustment is made so that the rear half core material 10 is aligned.

In this way, the bed 1 takes the shape of a chair and can be used as a chair. That is, the infant can push his/her Pj forward of the bed 1. At this time, the front part 2a of the bottom wall 2 extends along the back surface of the leg and also functions to protect the leg. In addition, the above-mentioned rising position at the rear of bed 1 is IN! ! Various modifications are also possible, and are not necessarily necessary.

To return bed 1 to its original bed shape, remove the bottom frame 12.

The reference numeral 1ζ used in the figure indicates that another pair of drawer links 28 (only the one on the front side is shown) used in corresponding parts are arranged on both sides of the bottom wall 2. . Each drawer link 28 is inserted into a pair of tube portions 029 extending in the front-rear direction provided on the baby carriage main body side,
- It is held so that it can slide in the front and back direction by the lever.

Therefore, when the drawer link 28 is pulled forward, it comes into contact with the lower surface of the lower frame 12 and maintains the horizontal posture of the lower frame 12. Conversely, the drawer link 28 is slid in the tangential direction, and the drawer link 28 is slid in the tangential direction. Once the drawer link 28 is stored in the ffl frame 29, such a drawer link 28 no longer exists below the lower frame 12, and the lower frame 12 is in a state of being rotated downward.

As a means for maintaining the horizontal posture of the lower frame 12, various modifications are possible, but on the other hand, it may not be necessary to provide a special member. That is, Fu Suna 1
In some cases, the fastener 14 also serves this function, and if the fastener 14 and related members have the necessary strength, there is no need to add another member 61.

In this example, the front parts 5 of the right side wall 5 and the right side wall 6 are
The feature f8 is that a gusset J30 is formed at each boundary between a and 5a and each rear portion 536b.

When this "town" 30 is made into a bed shape as shown in Fig. It is said to be a state! In some cases, a gap is provided between each front part 5a, 6i1 of left side wall 5 and right side wall 6 and each rear part 5b, etc. 6b. By doing this, when it is shaped like a chair, it is possible to give the infant's legs a resting position on both sides.

Note that FIG. 6 shows a state in which the foot cover 7 is released v1. When the fastener 27 is opened and the leg cover 7 is no longer needed, it may be omitted and disposed of as shown in FIG. Although not shown in the figures, a suitable string or the like may be used to maintain the spring-loaded state of the foot cover 7. 4: Oh, as shown by the imaginary line in Figure 6,
Even when the foot cover 7 is shaped like a chair, it may be left to cover the front of the infant's legs. Well,
As shown in FIG. 5, even if the bed is in the form of a bed, the foot cover 7 can be removed.

In the illustrated embodiment, the town 30 is placed on each of the left side wall 5 and the right side wall 6, but it may be placed on the outside.

Fig. 7 is a right side view of a baby carriage in which a further embodiment of the present invention has been installed, and the bed 1 is in the original bed shape. Fig. 8 shows the bed 1 of Fig. 7. FIG. 9 is a perspective view of the same bed 1, showing the bed 1 in a chair-like state. In FIGS. Portions corresponding to the constituent elements in the example are given the same reference numerals, and detailed explanations are omitted. A fastener 31 is separably attached to the boundary line between the front wall 3, the left side wall 5, and the right side wall 6. It will be done like this.

Further, it is preferable that the front wall 3 is formed to stand up substantially perpendicularly to the bottom wall 2 so that each of the sections 7, which will be described later, can be folded properly. In addition, the actual flI shown in the figure
! ! In the example, a foot cover is not provided, but a foot cover may be further formed by being tied 311i to the upper edge of the front wall 3.

To change from the bed state shown in FIGS. 7 and 8 to the chair state shown in FIG. The rear parts 5b and 6b are separated from each other, and the front wall 3 is folded over the left side wall 5. The front parts 5a and 5a of the right side wall 6 are folded. Note that this folding order may be reversed, and the front part 3 is folded over the front parts 5a and 6a. C Chinii.

Then, as shown in FIG. 3, the tension shuttle 15 is removed, the lower frame 12 is rotated downward, and the front of the bed 1 is lifted 118. Although not shown, the bottom wall 2
In order to maintain the overlapping state of the front part 2a of the front part 2a, the curved wall 3, and each front side 5a, 6a of the left side wall 5 and the right side wall 6, suitable separable joining means, such as hooks, buttons or velvet fasteners, etc. are used. Used6.
It may be 1'1.

In the above-mentioned embodiment, in order to maintain the states shown in FIG. 7 J3 and FIG. 8 and to enable the eight walls to be folded as shown in FIG. Preferably, each of the front parts 5a, 6a of 6 is loaded with 8 tiles. Further, the lower frame 12 is, for example, shaped like a 1-shape as shown in FIG.

As mentioned above, the reason why the front wall 3 is rented so as to stand up perpendicularly to the bottom wall 2 is as follows. That is, in the state shown in FIG. 9, the front end edges of the front portions 5a, 5a of the left side wall 5 and right side wall 6 are further forward and downward from the bending line between the bottom wall 2 and the front wall 3 in the folded state. This is to prevent it from protruding. Also, when performing the reverse folding as shown in Fig. 9,
That is, when the front parts 5a, 5a are folded so that they are under the front wall 3, the front parts 5a, 5a can be sandwiched between the front wall 3 and the bottom wall 2 as they are. This is to do so.

FIG. 10 is a perspective view showing still another embodiment of the present invention, showing the chair-like state. The live fetus example shown in FIG. 10 is the same as the embodiment shown in FIGS. 7 to 9, except for the following changes.

jQ core materials are inserted so that the angle between the front face v3 and the front part 2a of the bottom wall 2 is kept constant, and the front face W13 is formed so that it cannot be folded onto the bottom wall 2. In other respects, Example 2 is similar to the example shown in Figures 7 and 1-19. In this embodiment, the left side wall 5 and the right side wall 6 have 1. In particular, the fact that the front wall 3 stands perpendicularly to the bottom wall 2 has Rm. That is, the left side wall 5 and the left side wall 6
The fact that the front edge of each front part 5"+6n of the front part 5"+6n intersects perpendicularly to the lower part 11 allows it to be folded into the bottom wall 21- without being disturbed by the front wall 3.

Although various embodiments of the present invention have been described above, the method of folding the six walls of the chair 17 can be further modified in various ways. Possible joining means are:
Other than that, it is also possible to replace the bed with a 7-snare (hot tsuku, button, velvet), tenacity, etc.Also, in the above explanation, I did not mention the folding of the stroller, but it is possible to replace the bed with an IM. By devising various materials or ways of connecting each material,
A bed is also obtained which follows the folding movement of the baby carriage well, and such a bed can be used both for folding and folding baby carriages as well as for baby carriages which do not have their own folding mechanism.
