Description

Diaper changing table

Technical Field

The present invention relates to a diaper changing station.

Background

A diaper changing table provided on a wall surface of a toilet or the like of a public facility such as a train station as a base for changing diapers of infants is known (for example, patent literature 1). The diaper changing table shown in patent document 1 generally has a flat plate-shaped changing table body, a pad provided on the changing table body and on which an infant lies, and a base fixed to a wall surface and rotatably supporting the changing table body. Therefore, the diaper changing table can be switched between an unused state in which the changing table main body is disposed parallel to the wall surface and a used state in which the changing table main body is disposed perpendicular to the wall surface, that is, horizontally.

In the construction of the diaper changing table, it is necessary to change the direction of the pad with respect to the changing table main body according to the position of the wall surface to be provided or the surrounding space. Further, there are cases where the pad must be replaced due to dirt, breakage, or the like caused by the continued use of the diaper changing station. Therefore, the pad can be attached to and detached from the exchange table main body.

The pad is attached to the exchange table body by, for example, providing a plurality of claw-shaped protrusions on the bottom surface of the pad facing the upper surface of the exchange table body, inserting the protrusions into holes of the exchange table body provided at positions corresponding to the protrusions, and fitting the protrusions into the holes in a snap-fit manner.

Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In all the drawings, common reference numerals are given to the corresponding components.

Fig. 1 is a perspective view of a diaper changing station 1 according to an embodiment of the present invention. Fig. 2 is a view of the diaper changing station 1 in a use state when viewed from directly above.

The diaper changing table 1 has a belt 2 for protecting an infant, a changing table body 10, a pad 20 provided on the changing table body 10, and a base 30 fixed to a wall surface. The exchange table main body 10 is a flat plate-like member, and a pad 20 is fixed thereto. The pad 20 has: a flat pad surface 21 covered with a cushioning member having cushioning properties and on which an infant lies, a head side portion 22 in which the head of the infant lying down is disposed, and a foot side portion 23 in which the feet are disposed.

The base 30 has an upper base 31 and a lower base 32. The upper base 31 rotatably supports the exchange table main body 10. Therefore, the diaper changing table 1 can be switched between an unused state (not shown) in which the changing table body 10 is disposed parallel to the wall surface, and a use state (fig. 1) in which the changing table body 10 is disposed vertically, i.e., horizontally, with respect to the wall surface. Since the lower base 32 is a leg-shaped member that supports the upper base 31 from below in a reinforced manner, the upper base 31 can be omitted when it is sufficiently fixed to the wall surface.

In fig. 2, a wall surface (not shown) to which the changing table 1 is fixedly attached is located above in the drawing. The head side portion 22 of the pad 20 is disposed on the left side in the drawing, and the foot side portion 23 of the pad 20 is disposed on the right side in the drawing. Therefore, the caretaker stands on the right side of the changing table body 10 toward the wall surface, and performs the changing operation of the diaper of the infant, and the like. On the other hand, if there is another wall surface or an obstacle on the right side of the wall surface where the diaper changing table 1 is provided and a sufficient space cannot be secured, the pad 20 is rotated 180 degrees and mounted on the changing table body 10. That is, in fig. 2, in order to turn the lying infant upside down, the head side portion 22 of the pad 20 is disposed on the right side, and the foot side portion 23 of the pad 20 is disposed on the left side. At this time, the caretaker stands on the left side of the changing table body 10 toward the wall surface to perform the changing operation of the diaper of the infant or the like.

The changing table body 10 is provided with a plurality of locations for placing articles such as luggage for facilitating operations such as changing diapers by a caretaker. For example, in fig. 2, a large piece of luggage can be placed on a wide planar area a of the exchange table main body 10 located above the pad 20. The planar area a is an area formed between the outer peripheral wall of the pad 20 and the front surface of the upper base 31. That is, the planar area a is an article placement portion provided near the pad 20. Further, recesses B constituting hooks for hooking luggage are formed near two corners of the exchange table main body 10 separated from the wall surface.

In the diaper changing table 1 in the use state, the changing table main body 10 includes: a lower housing 11 located at the bottom surface, an upper first housing 12 having a planar area a, and an upper second housing 13 having a recess B. The upper first casing 12 and the upper second casing 13 are mounted on the lower casing 11 by a coupling method such as bolt coupling while sandwiching the pad 20 therebetween. Thus, the upper first housing 12 and the upper second housing 13 perform the function of a mounting member separate from the pad 20. The lower case 11, the upper first case 12, and the upper second case 13 are formed by integrally molding a hard plastic such as ABS resin.

Fig. 3 is a perspective view of the pad 20. Fig. 4 is an additional perspective view of pad 20. Fig. 5 is a longitudinal cross-sectional view of the pad 20. Fig. 6 is a top view of the pad 20, the upper first housing 12, and the upper second housing 13. In fig. 3 to 6, the buffer member covering the surface of the pad 20 is omitted. That is, the pad 20 is formed by covering a structure obtained by integrally molding a hard plastic such as ABS resin with a cushioning member. In the pad 20, the head side when the infant is viewed in a supine state is also referred to as "up", the foot side is referred to as "down", and the left and right sides are also referred to as "left and right".

As shown in fig. 2 and 6, the pad 20 has a substantially rectangular outer shape when viewed from directly above and directly below. As described above, the cushion 20 has the head side portion 22 and the foot side portion 23, and between the head side portion 22 and the foot side portion 23, there is the trunk portion 24 narrowed toward the center. A peripheral wall 25 formed by a continuous curved surface is formed at the outer periphery of the pad 20. In fig. 6, the shape and structure of the pad 20 and the upper first and

second cases

12 and 13 are shown separately for comparison.

As shown in fig. 3 and 5, the peripheral wall 25 is formed to be higher on the left and right and head sides and lower on the foot side. Specifically, when the length in the vertical direction from the cushion surface 21 is set to be the height, the left and right first peripheral wall portions 25a have a height of 70mm, for example, and the head-side second peripheral wall portion 25b has a height of 85mm, for example. Further, the third peripheral wall portions 25c on the left and right of the trunk portion 24 of the cushion 20 are formed slightly lower than the surrounding, for example, have a height of 40 mm. The fourth peripheral wall portion 25d on the foot side of the pad 20 has a height of 30mm, for example, and has an inclined surface 25e which extends toward the pad surface 21 and is gentle compared with the corresponding portion of the other peripheral wall 25.

By providing the pad 20 with the above-described structure, it is possible to protect a lying infant in a manner of wrapping it in and to restrict movement of the infant in a more comfortable manner. That is, since the left and right first peripheral wall portions 25a are formed to be high and have the narrowed trunk portion 24, the turning-over of the infant can be prevented, and the diaper changing operation can be smoothly performed. In other words, the width of the pad 20 is set to be narrower to prevent the infant from turning over, and as a result, only the planar area a (article placement portion) of the exchanging table body 10 for placing the luggage can be further enlarged without increasing the overall size as compared with the conventional products.

Further, by providing the right and left first peripheral wall portions 25a adjacent to the planar area a of the exchange table main body 10 with a certain level of height, even if a caretaker places luggage on the planar area a, the luggage is prevented from falling to an infant lying on the mat 20. Further, by forming the second peripheral wall portion 25b on the head side to be the highest, the infant is prevented from moving upward while stepping on the cushion surface 21 in a lying state. Further, since the fourth peripheral wall portion 25d on the foot portion side is formed to be lower, it is possible to prevent the infant from falling down, and to seat the infant along the inclined surface 25e of the peripheral wall 25, and to easily perform shoe replacement or the like.

The pad 20 has a laterally extending protrusion 26. The term "lateral" refers to a direction parallel to the mat surface 21. The term "extending in the lateral direction" does not necessarily mean parallel to the mat surface 21 in a strict sense, and includes a case of extending obliquely downward or the like including a component of the lateral direction. Specifically, in the present embodiment, two or a total of four protrusions 26 extend from the outer peripheral surfaces of the left and right first peripheral wall portions 25a of the pad 20, respectively, outward in the left-right direction, that is, in the lateral direction. Each of the projections 26 is a member parallel to the pad surface 21 and formed in a flat plate shape as a whole.

Fig. 7 is a perspective view of the upper first housing 12 mounted on the lower housing 11. The upper first housing 12 and the upper second housing 13 will be described with reference to fig. 7 and 6.

Referring to fig. 7, the upper first housing 12 has two recesses 14 as receiving portions for receiving the protrusions 26 at positions corresponding to the two protrusions 26 on the left and right sides of the pad 20. As shown in fig. 6, the upper second housing 13 also has two recesses 14 as receiving portions for receiving the protrusions 26 at positions corresponding to the two protrusions 26 on the other side of the pad 20. The peripheral edge portions of the upper first case 12 and the upper second case 13 facing the pad 20 are formed so as to complement the outer shape of the left and right first peripheral wall portions 25a of the pad 20.

As shown in fig. 7, curved groove portions 15 are formed on both end portions of the surface of the upper first housing 12 facing the pad 20 and in the vicinity of the peripheral edge portion. Although not shown, similar grooves are formed at corresponding positions of the upper second housing 13. Therefore, the upper first housing 12 and the upper second housing 13 have a total of four groove portions 15. Each groove 15 is formed to fit into four thin corners 27 (fig. 4 and 6) of the pad 20.

Fig. 8 is a perspective view showing engagement of the projection 26 with the recess 14. Fig. 9 is a cross-sectional view showing engagement of the protrusion 26 with the recess 14. Although fig. 8 shows engagement between the recess 14 of the upper second housing 13 and the projection 26 of the pad 20, engagement between the projection 26 of the pad 20 and the recess 14 of the upper first housing 12 is also the same. The projection 26 of the pad 20 is disposed below the recess 14, that is, on the lower case 11 side in a state where the pad 20 is attached to the exchange table main body 10. Therefore, the protrusions 26 of the pad 20 engage with the upper first housing 12 and the upper second housing 13, that is, with the recesses 14 of the exchange table main body 10, with respect to the movement of the pad 20 in the direction of disengagement from the exchange table main body 10 (upward in fig. 9), and the disengagement of the pad 20 is restricted. Further, the recess 14 is formed by using the partition walls 14a (fig. 8) surrounding from three directions, thereby restricting the movement of the projection 26.

Fig. 10 is a diagram showing a method of mounting the pad 20. The operation of attaching the pad 20 is performed when changing the pad 20 to a new pad 20 by changing the pad up and down during the construction of the diaper changing station 1, or by causing dirt or breakage of the cushioning member of the pad 20. The operation of replacing the pad 20 is performed in a position where the changing table main body 10 is horizontal, that is, in a use state of the diaper changing table 1.

First, the operator places two protrusions 26 on the side of the pad 20 facing the upper first casing 12 in the vicinity of the recess 14 of the corresponding upper first casing 12 from the state of the lower casing 11 and the upper first casing 12 shown in fig. 7. At this time, in order to make the pad 20 fit into the groove portion 15 of the upper first housing 12 while finally engaging the protrusion 26 with the recess 14, the pad 20 is rotated about an axis parallel to the rotation axis of the exchange table main body 10, that is, is tilted with respect to the exchange table main body 10. In this state, the upper second housing 13 is prepared, and the mounting is performed such that the two protrusions 26 on the other side of the pad 20 are engaged with the corresponding recesses 14 of the upper second housing 13, and the corner portions 27 of the pad 20 are fitted into the groove portions 15 of the upper second housing 13. This state is shown in fig. 10.

Fig. 8 is a view of the upper second housing 13 and the pad 20 in this state as viewed from below. Next, when the upper second housing 13 is lowered downward so as to be fitted to the lower housing 11, the corner portions 27 of the pad 20 are fitted to the groove portions 15 of the upper first housing 12, and the upper second housing 13 and the pad 20 are disposed on the lower housing 11. Finally, the upper second housing 13 is fixed by a coupling method such as bolt coupling, and the mounting is completed. Further, since the pad 20 is engaged with the upper first housing 12 and the upper second housing 13 and sandwiched between the upper first housing 12 and the upper second housing 13, a coupling method for fixing the same is not required.

In the above-described mounting step, from a state where the upper first housing 12 is mounted on the lower housing 11 in advance (fig. 7), the pad 20 side in a state where the upper second housing 13 is integrally mounted is brought into contact with the upper first housing 12 side, and the mounting is completed while rotating. However, for example, in the case of performing operations by a plurality of persons, the upper first housing 12, the pad 20, and the upper second housing 13, which are integrally mounted in advance, may be mounted so as to cover the lower housing 11 from above. That is, the upper first housing 12, the pad 20, and the upper second housing 13, which are integrally mounted in advance, are in the following states: the corner 27 of the pad 20 is fitted into the groove 15 of the upper first housing 12 and the upper second housing 13, and the projection 26 of the pad 20 is engaged with the recess 14 of the upper first housing 12 and the upper second housing 13, so that the mounting can be easily performed.

As shown in fig. 6, the shape of the pad 20 including four protrusions 26 is point-symmetrical about a center point C. Therefore, even if the pad 20 is rotated 180 degrees around the center point C in fig. 6, that is, even if the pad 20 is disposed so as to be turned upside down for a lying infant, the pad can be mounted so as to be engageable with the exchange table main body 10. When the arrangement of the pad 20 is changed, the pad 20 is detached from the exchange table main body 10 by performing an operation in a reverse step to the above-described mounting.

The recess 14 of the engaging portion of the upper first case 12 and the upper second case 13, that is, the recess 14 of the exchange table main body 10, and the projection 26 of the pad 20, which is the engaged portion, may each have any shape as long as they can be engaged with each other with respect to the direction in which the pad 20 is disengaged from the exchange table main body 10. For example, the projection 26 may be cylindrical instead of flat. The recess 14 as the receiving portion need not be formed by the partition wall 14a, but may be a flat portion, or may be a hole 16 into which the projection 26 is inserted, as shown in fig. 11. Further, a protrusion extending in the lateral direction may be provided on the exchange table main body 10 side, and a recess or hole portion capable of engaging with the protrusion may be provided on the pad 20 side.

According to the present invention, the pad 20 is not required to be screwed to the exchange table main body 10, and only the upper first casing 12 and the upper second casing 13 need to be screwed, so that the attachment and detachment can be easily performed. Therefore, the workability at the time of changing or replacing the arrangement of the pads 20 is improved, and smooth construction and subsequent maintenance work of the diaper changing station 1 can be realized. Further, since the pad 20 is not fitted by snap fasteners which cause large elastic deformation of the members, but the pad 20 is restricted from being detached from the exchange table main body 10 by engagement of the projections 26 and the recesses 14, which are relatively rigid, a mounting mechanism excellent in durability can be realized. In addition, since the cushion member of the cushion 20 does not interfere with other members such as the upper first housing 12 in the mounting structure of the cushion 20, the cushion member is not damaged.
