DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of an infant bed according to the present invention. In the figure, reference numeral 1 denotes a deployable wall-fixed infant bed, which includes a bed portion 2 comprising a bed main body 3 and a bed base 4 on which the bed main body 3 is placed and fixed, and a wall fixed to the wall surface. The frame 6 includes a hinge portion 8 that pivotally attaches the bed base 4 to the wall-fixing frame 6 in a deployable manner. Since the configuration so far is the same as each component of the wall-fixed baby bed 1 ′ described in FIGS. 8 to 12, detailed description of each component will be omitted.
The difference is that, in such a wall-fixed infant bed 1, the two restraining belts 51, 52 are not formed from the width direction both ends of the bed body 3 but from the width direction center and the width direction both edges. It is a point which comes out from each intermediate area | region of this and couple | bonds with the buckle 9 in the center part of a bed.
An appropriate distance between the two restraining belts 51 and 52 in the bed body 3 is about 180 mm, which is the torso width of the infant.
[0016]
Therefore, the reason why the diaper change and the like can be smoothly performed by using the wall-fixed baby bed 1 having the bed main body 3 of the restraining belts 51 and 52 will be described with reference to FIG.
FIG. 2 is a sectional view showing a state in which an infant is restrained by a restraining belt according to the present invention. In FIG. 2, restraining belts 51 and 52 are respectively arranged in the width direction central portion O and the width direction of the bed body 3. The baby B is fixed to the central portion O of the bed main body 3 with the buckle 9 by using the belts 51 and 52 for restraint, which come out from intermediate regions P1 and P2 between the edge portions E1 and E2.
By doing so, the spaces S1 and S2 formed between the restraining belts 51 and 52 on both sides of the infant B and the bed body 3 are very small compared to the spaces S1 ′ and S2 ′ in FIG. In this case, it is no longer possible for the infant B to move laterally or turn over in the direction of the space S1 or S2, and therefore, changing diapers and the like can be performed smoothly.
[0017]
Next, the second embodiment of the present invention in which one of the restraining belts 51 and 52 (52 in the figure) is extended and retracted from an intermediate region P2 between the width direction central portion O and the width direction edge E2 of the bed body 3. A simple telescopic configuration according to the embodiment will be described with reference to FIG. 4A shows a state in which an infant is restrained on the bed body 3 in a cross section near the abdomen, and FIG. 4B shows a view of FIG. 4A viewed from the back side of the bed body 3. ing.
In the figure, the restraining belt 51 protrudes from an opening 35 opened in an intermediate region P1 between the width direction central portion O and the width direction edge E1 of the bed body 3, and one end is on the back side of the bed body 3. A buckle 91 is fixed to the other end.
On the other hand, the restraining belt 52 protrudes from an opening 36 opened in an intermediate region P2 between the width direction central portion O and the width direction edge E2 of the bed body 3, and one end is fixed on the back side of the bed body 3. The other end has a buckle 92 fixed thereto. Then, on the back side of the bed main body 3, the restraining belt 52 extends to the intermediate region P <b> 2 through the opening 72 a of the suspension ring member 72. One end of the tension spring 7 is fixed to the hanging ring member 72, and the other end is fixed to the vicinity 71 of the back side edge of the bed body 3. As a result, the suspension ring member 72 is always pulled in the direction of the width direction edge E1 by the tension spring 7, and the restraining belt 52 is always pulled to the back side of the bed body 3.
Moreover, the space | interval of the opening part 35 and the opening part 36 is about the body width | variety (about 180 mm) of the infant.
Therefore, when the infant B is restrained to the bed main body 3 by using the restraining belt 52, the infant B is constantly pressed against the bed main body 3, making it difficult for the infant B to move laterally and turn over. Etc. can be performed more smoothly.
[0018]
FIG. 5 shows a third embodiment of the present invention and is a perspective view of the bed body 3.
In FIG. 4, the restraining belts 51 and 52 described with reference to FIG. 4 protrude from the intermediate region between the center portion in the width direction and the edge portion in the width direction of the bed body 3.
Such a bed main body 3 is formed by curving (radius R) so that the widthwise central portion is recessed with respect to the widthwise end edges 31, 31. With such a configuration, a force directed toward the central portion in the width direction of the bed main body 3 always acts on the infant, so that the infant is more and more laterally moved and turned over by a synergistic effect with the action of the restraining belts 51 and 52 of the present invention. Therefore, changing diapers and the like can be performed more smoothly.
[0019]
FIG. 5 further shows a fourth embodiment of the present invention.
In the figure, a characteristic feature is that a cushioning member 37 such as sponge or urethane material is provided in the vicinity of the longitudinal edge portions 33 and 34 (34 in the figure) of the bed body 3.
The infant restrained to the center of the bed is not only prevented from moving in the left-right direction, but also moved in the head direction is softly blocked by the cushioning member 37. However, the head does not move upward with the cushioning member 37, so that the diaper can be changed smoothly.
In addition, because it uses a cushioning member, it protects the head when in use, and when it is not in use, it automatically contracts when the bed body is folded, so there is no obstacle to downsizing the entire bed. There is no effect.
[0020]
FIG. 6 shows a fifth embodiment of the present invention, which uses restraint means instead of the cushioning member 37 of FIG. FIG. 6A shows the undeployed state of the restraining means, and FIG. 6B shows the deployed state of the restraining means.
In the figure, 3 is a bed main body and 38 is a restraining means. The restraining means 38 is detachably mounted on the bed main body 3 by a hinge 39.
When the bed main body 3 is not used, the restraining means 38 is folded by a hinge 39 as shown in FIG. As a result, the height H1 of the restraining means 38 is lowered, and is within the range of the height difference between the central portion in the width direction of the bed main body 3 and the end portions 31 and 32 in the width direction due to the formation of the curve (arm) in FIG. There is no obstacle to the size of the entire bed by folding.
Further, when the bed body 3 is used, the restraining means 38 may be erected on the bed body 3 by a hinge 39 as shown in FIG. As a result, the height H2 of the restraining means 38 is sufficiently high, and a sufficient height to prevent the infant's head from moving upward is obtained. As the restraining means 38, a material soft to the head is used.
As a result, the infant restrained to the center of the bed is not only prevented from moving in the left-right direction, but is also prevented from moving toward the head by the restraining means 38 in the upright state. Even if the head is kicked up, the head does not move upward with the restraining means 38, so that the diaper can be changed smoothly.
[0021]
Of course, the present invention is not limited to the above.
For example, although two restraining belts were used on the left and right, a single restraining belt may be used. In that case, a locking tool (hook, magnet, fastener, etc.) is attached to the tip of the restraining belt, A locked tool corresponding to the locking tool is attached on the bed body 3.
Although there are two restraint belt take-out openings, three or more take-out openings may be provided to move the restraint belt take-out openings to the outside as the baby grows.
Tensioning of the restraining belt can be easily realized by replacing the entire restraining belt or a part thereof with rubber.
[0022]
【The invention's effect】
As described above, when the deployable wall-fixed infant bed according to the present invention is used, the entire bed can be reduced in size, and the infant can be securely fixed and restrained on the bed, so that changing of diapers and the like is smooth. Will be able to do.
