[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diaper changing bed device used for changing a diaper for an infant.

[0002]

2. Description of the Related Art In a station or other public facility, a department store, a shopping center, etc., a diaper changing bed used for changing a diaper of a baby, which is mounted on a wall of a washroom, a toilet, etc. As described in Japanese Patent Application Publication No. 4-75610, a base portion attached to a wall surface of a building, and a bed portion pivotally attached to the base portion so as to be freely foldable are provided. And the bed is rotated upward after use to fold the bed into a folded position.

[0003]

In the conventional diaper changing bed, the size of the bed portion in the front-rear direction is made larger than the size in the left-right direction, and the bed portion is formed in a vertically long shape in the front-rear direction. Since the bed portion is tilted so as to be longer in the front-rear direction, and the baby is laid on the bed portion in the front-rear direction, there are the following drawbacks.

That is, when the diaper is to be used for exchanging diapers, etc., the baby is laid on the bed in the front-rear direction.
Parents such as mothers exchange diapers while standing either in front of the bed or on the left or right. Therefore, when the parent stands on the front side of the bed, the left and right sides of the bed are open, and when the parent stands on either the left or right of the bed, the opposite side opens. Therefore, there is a risk that the infant on the bed may fall.

[0005] Therefore, in order to prevent the infant from falling, it is indispensable to provide a fall-preventing wall which protrudes greatly on both the left and right sides of the bed. Care must be taken
There are safety issues for infants. In addition, the bed portion is vertically elongated in the front-rear direction, and if an infant is laid on the bed portion, a large load will be applied to a position far away from the hinge. In order to reduce the size, there is a structural disadvantage in terms of strength.

Further, the left-right dimension of the base part is made larger than the left-right dimension of the bed part, and a pair of side wall parts projecting forward is formed on both left and right sides of the base part in a vertical direction. Since the rear end of the bed portion is fitted between the lower portions of the pair of side wall portions to pivotally support the bed portion and the base portion with the hinge, the bed portion is folded in the folded posture so that the bed portion is located on the left and right side wall portions of the base portion. Although it can fit in the middle and can prevent the hinge from being exposed, there is a disadvantage that the entire apparatus becomes large and requires a very large installation area.

[0007] That is, the bed portion is provided with a fall-preventing wall, and the amount of projection of the bed portion from the entire wall surface to the front is large even when the bed portion is folded, and the left and right side walls of the base portion in the folded position. Since the bed is inserted between the sections, the size of the base section in the left-right direction becomes very large and the size becomes large. For this reason, there is a drawback that the installation location is limited to a place where there is sufficient room in the left, right, front and back.

Further, since the base portion and the bed portion are increased in size, the stand portion formed integrally with the base portion and grounding on the floor surface to support the base portion is also increased in size, thereby increasing the overall manufacturing cost. There are drawbacks. The present invention has been made in view of the above-mentioned conventional problems, and aims to provide a diaper changing bed device which can secure sufficient strength with a simple structure, has a small size, has little restriction on an installation place, and can be used easily and safely. I do.

When the bed 11 is in the use position D, the baby is placed on the bed 11 and laid down sideways, and the baby's body is fastened with the safety belt 12 and stopped. Then, in that state, the diaper of the infant is replaced. At this time, the load W of the infant
Hangs downward on the bed 11 as shown in FIG. However, since the position where the load W of the baby is applied is closer to the hinge 26 as compared with the case of the horizontal shape and the vertical shape, the hinge 2
6. The load on the contact portion between the base frame 15 and the bed frame 28 can be reduced.

In addition, since the bed 11 is mounted on the support stand 3 via the base 10, a tensile load is applied to the wall 1 on the upper side of the support stand 3 via the support stand 3, and The lower side acts as a pressing load on the wall surface 1. Therefore, the tensile load on the wall 1 can be reduced as compared with the case where the base 10 is directly attached to the wall 1, so that the diaper changing bed 9 can be safely used even on a mortar wall having relatively weak wall strength. And it is possible to securely attach.

The support stand 3 has a grounding portion 5 at the lower end of the column 4 in contact with the floor 2, and a tapping screw 7 for fixing the support stand 3 to the wall 1, and a support stand 3.
A strong load is not applied downward as in the case where the lower end of the is raised from the floor surface 2. Therefore, the wall strength is not required to be as high as this point.

The used old diaper removed from the baby when changing the diaper is removed from the dust box 14 below the bed 11.
It is only necessary to put it in through the input port 59, and its disposal is easy. The used diapers and the like thrown in through the slot 59 enter the inner box 58 and accumulate.

When the diaper replacement is completed, the bed 11 is rotated upward about the axis of the hinge 26, and the bed 11 is folded along the base 10. At this time, gas spring 13
Since the urging force acts on the bed 11 in the folding direction, the bed 11 can be folded lightly.

The diapers and the like accumulated in the inner box 58 are removed by removing the upper lid 60 of the outer box 57 with the bed 11 folded, and pulling the inner box 58 upward.
Remove it from 58 and throw it away. By arranging the dust box 14 below the diaper changing bed 9 in this way, the lower side of the diaper changing bed 9 does not become a dead space, and a narrow space such as a washroom can be effectively used, The diaper changing bed 9 and the dust box 14 can be designed in harmony.

FIG. 11 shows a second embodiment of the present invention, in which the grounding portion 5 is extended rearward of the column 4 and the column 4 is connected to the grounding portion.
5 is reinforced by a reinforcing plate 63 from the side. Such a support stand 3 has a recess 64
It is effective when there is such as. In addition, if the length of the grounding part 5 is sufficiently secured and the strength of the support 4 is also ensured, the support stand 3 can be fixed only by fixing the grounding part 5 to the floor 2 without fixing the support 4 to the wall 1. It can be mounted in a self-supporting state.

FIG. 12 shows a third embodiment of the present invention, in which the bed 11 in the use posture D is supported from below on the upper surface of the outer box 57 of the dust box 14. In this case, since the bed unit 11 is supported by the dust box 14, the burden on the hinge 26 can be reduced, and even when the hinge 26 is damaged, the bed unit 11 does not immediately fall, thereby preventing an unexpected accident. , Safety is significantly improved.

The outer box 57 has a charging port on the front side.
59 and the like are provided, and a cushion material 65 is mounted on the upper surface of the upper lid 60. In this case, a large opening is provided at the lower part on the front side of the outer box 57, and the inner box is
58 may be taken in and out.

In addition to the structure exemplified in each embodiment, the dust box 14 may be fixed to the support stand 3 or the dust box 14 itself may constitute a part of the support stand 3. In addition, the support stand 3 can omit the grounding portion 5 so that the lower end of the support 4 directly contacts the floor 2. Further, the support stand 3 may be fixed to the wall surface 1 and the floor surface 2 with anchor bolts. In the case of the third embodiment, a slight gap may be secured between the bed 11 in the use posture D and the dust box 14 so that they do not directly contact each other in a normal state.

The amount by which the bed portion 11 projects forward in the tatami posture U can be reduced.

Since the bed 11 is horizontally long and the baby can be laid on the bed 11 in the use posture D in the left and right direction, even when the baby is laid on the bed 11, Compared to the conventional method of lying down in the front-back direction, the position where the load is applied approaches the hinge 26,
The load on the hinge 26 can be reduced, and sufficient strength can be ensured with a small and simple structure.

[0057] While forming the opening 42a toward the rear end portion of the bed 11, the base portion 10 is provided with a projecting member 19 which projects forwardly into the bed portion 11 through the opening 42a, the projection
Since the member 19 is pivotally connected to the bed portion 11 by the hinge 26 in the bed portion 11, the hinge 26 can be disposed so as to protrude forward from the base portion 10 even though the hinge 26 can be disposed. There is no direct exposure to the upper side. Therefore, there is no danger that the infant or the like on the bed 11 may pinch a finger or the like by mistake, and the infant can be safely laid on the bed 11.

The bed 11 has a horizontally long shape in the left-right direction, and an opening formed on the rear side of the bed 11.
The projecting member 19 located in the
Therefore, it is not necessary to make the dimension in the left-right direction of the base portion 10 larger than that of the bed portion 11. Therefore, the entire bed apparatus including the bed section 11 and the base section 10 can be reduced in size, and the horizontally long bed section can be reduced.
If there is enough room for the 11 to fit in the left and right direction, the base 10 side can be installed at a required portion such as the wall surface 1. In front of the wall 1 etc., a horizontally long bed
It is enough if there is enough space to be able to drop 11 in the use position D, so the installation area is very small compared to the conventional, it can be installed sufficiently in narrow places, and the amount of protrusion in the folding position U is small. It is not often disturbed in conjunction with this.

Since the urging means 13 for urging the bed 11 in the folding direction is provided so as not to be exposed to the outside,
When the bed unit 11 in the folding position U is moved to the use position D, the bed unit 11 can be prevented from suddenly falling, and the used bed unit 11 can be easily folded into the folding position U, thereby holding a baby. Even the guardian in the state can easily and safely operate the bed unit 11 with one hand and use it easily. In addition, there is no danger that the infant or the like on the bed 11 may accidentally pinch a finger or the like by the urging means 13, and the infant can be laid down on the bed 11 with confidence.

The lower end is in contact with the floor 2 and the base 10
Support stand 3 for supporting the
When the 10 is mounted on a required portion such as the wall surface 1, the burden on that portion can be reduced.

According to the third aspect of the present invention, in the first or second aspect of the present invention, the width of the support stand 3 is smaller than the horizontal dimension of the base 10 and the bed 11. Because of the vertically long configuration, the following remarkable effects are obtained. The support stand 3 on the lower side of the base portion 10 and the bed portion 11 is small, so that the whole can be significantly reduced in size and the production cost can be reduced.

According to the fourth aspect of the present invention, in the first, second or third aspect of the present invention, a pair of support stands 3 are provided at an interval in the left-right direction. Since the base 10 is attached to the upper part, the following remarkable effects are obtained. The individual support stands 3 can be made simple and simple, can be manufactured at low cost, and the base 10 can be reliably supported by the pair of support stands 3.

Other Disclosure FIGS. 13 and 14 show a mobile diaper changing bed apparatus. As shown in FIGS. 13 and 14, the support stand 3 is provided with a frame 74 in the front-rear direction at the lower end of each column 4, and the both frames 74 are connected to each other at both front and rear ends or at a middle portion by a horizontal bar 75. . Caster wheels 76 for movement are provided at both front and rear ends of each underframe 74. The caster wheels 76 are provided with brakes, for example, two of them on the front side, so that if the brakes are applied at the installation location, the support stand 3 can be fixed so as not to move unstably.

The dust box 14 is detachably or fixedly mounted on a pair of left and right underframes 74 at the front side of the column 4. In order to make the dust box 14 detachable, it is preferable in terms of strength to connect the middle part of each support 4 and the front end of the underframe 74 with an oblique reinforcing member 77. When the dust box 14 is fixed, if the dust box 14 is fixed to the support 4 and the underframe 74 with screws or the like, the dust box 14 can reinforce the space between the support 4 and the underframe 74.

The dust box 14 has an outer box 57 and an inner box 58. On the front side of the outer box 57, an inlet 59 with a palate 62 is located at the upper part, and a large opening 78 with a double door 77a is located at the lower part. The inner box 58 is inserted into and removed from the opening 78 in the front-rear direction.

In the diaper changing bed apparatus having such a configuration, since the support stand 3 is provided with the caster wheels 76, the entire bed apparatus can be easily moved to an appropriate installation location. At
It is very convenient when installed in the washroom for a short time. In addition, since the entire bed apparatus is self-supporting, it can be installed simply by applying a brake to the caster wheels 76 to stop unstable movement, and there is no need to fix the support stand 3 to the wall surface. is there.
