  FIG. 1 is a perspective view of a diaper changing table 1 according to an embodiment of the present invention, and FIG. 2 is a view of the diaper changing table 1 in use as seen from directly above.

  The diaper changing table 1 includes a belt 2 for protecting an infant, a changing table main body 10, a mat 20 provided on the changing table main body 10, and a base 30 fixed to a wall surface. The exchange base body 10 is a flat plate-like member to which the mat 20 is fixed. The surface of the mat 20 is covered with a cushion member having cushioning properties, and a flat mat surface 21 on which an infant is laid down, a head side portion 22 on which the head of the laid infant is placed, and legs are arranged. Leg side portion 23.

  The base 30 has an upper base 31 and a lower base 32. The upper base 31 rotatably supports the exchange base body 10. Therefore, the diaper changing table 1 includes an unused state (not shown) in which the changing table main body 10 is arranged in parallel to the wall surface and a used state in which the changing table main body 10 is arranged perpendicular to the wall surface, that is, horizontally ( FIG. 1) is a foldable switchable type. Since the lower base 32 is a leg-like member that supports the upper base 31 from below, it can be omitted if it is sufficient to fix the upper base 31 to the wall surface.

  In FIG. 2, a wall surface (not shown) on which the diaper changing table 1 is fixedly attached is located in the upper part of the drawing. The head side portion 22 of the mat 20 is disposed on the left side in the figure, and the leg side portion 23 of the mat 20 is disposed on the right side in the figure. Accordingly, the guardian stands on the right side of the exchange base body 10 toward the wall surface, and performs a diaper changing operation for the infant. On the other hand, when the sufficient space cannot be secured due to another wall or obstacle on the right side of the wall on which the diaper changing table 1 is installed, the mat 20 is rotated 180 degrees and attached to the changing table main body 10. It is done. That is, in FIG. 2, the head side portion 22 of the mat 20 is arranged on the right side and the leg side portion 23 of the mat 20 is arranged on the left side so that the upside down of the laid infant is upside down. At this time, the guardian stands on the left side of the exchange base body 10 toward the wall surface, and performs a diaper changing operation for the infant and the like.

  For the convenience of a guardian who performs work such as changing diapers, the exchange table body 10 is provided with several places for placing articles such as luggage. For example, a large baggage can be placed in a relatively wide plane area A of the exchange base body 10 located above the mat 20 in FIG. The planar area A is an area formed between the outer peripheral wall of the mat 20 and the front surface of the upper base 31. That is, the planar area A is an article placement portion provided in the vicinity of the mat 20. Further, in the vicinity of two corners separated from the wall surface of the exchange base body 10, a recess B constituting a hook for hooking a load is formed.

  In the diaper changing table 1 in use, the changing table main body 10 includes a lower housing 11 located on 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 housing 12 and the upper second housing 13 are attached to the lower housing 11 by a coupling means such as screwing while sandwiching the mat 20 therebetween. Accordingly, the upper first housing 12 and the upper second housing 13 serve as separate mounting members for the mat 20. The lower housing 11, the upper first housing 12, and the upper second housing 13 are formed by integrally molding a hard plastic such as ABS resin.

FIG. 3 to 6, the cushion member that covers the surface of the mat 20 is omitted. That is, the mat 20 is formed by covering a structure integrally formed with hard plastic, for example, ABS resin, with a cushion member. In the mat 20, the head side is also referred to as “upper”, the leg side is also referred to as “lower”, and the left and right are referred to as “left and right” as they are viewed from the infant with the infant lying on their back.

  As shown in FIGS. 2 and 6, the mat 20 has a substantially rectangular outer shape when viewed from directly above and directly below. As described above, the mat 20 includes the head-side portion 22 and the leg-side portion 23, and the trunk portion narrowed toward the center between the head-side portion 22 and the leg-side portion 23. Part 24. A peripheral wall 25 constituted by a continuous curved surface is formed on the outer periphery of the mat 20. In FIG. 6, the mat 20 and the upper first housing 12 and the upper second housing 13 are shown apart from each other for comparison in shape and structure.

  As shown in FIGS. 3 and 5, the peripheral wall 25 is formed so that the left and right sides and the head side are high, and the leg side is formed low. Specifically, assuming that the length in the vertical direction from the mat surface 21 is a height, the left and right first peripheral wall portions 25a have a height of, for example, 70 mm, and the head-side second peripheral wall portion 25b has a height of, for example, 85 mm. Has a height of The left and right third peripheral wall portions 25c of the body portion 24 of the mat 20 are formed slightly lower than the surroundings and have a height of, for example, 40 mm. Further, the fourth peripheral wall portion 25d on the leg portion side of the mat 20 has a height of, for example, 30 mm, and is more inclined than the corresponding portion of the other peripheral wall 25 extending toward the mat surface 21. 25e.

  When the mat 20 has the above-described configuration, it is possible to protect the sleeping infant so as to wrap it and to gently restrict the movement of the infant. That is, the right and left first peripheral wall portions 25a are formed high and the narrowed trunk portion 24 prevents the baby from turning over, and the diaper can be exchanged smoothly. In other words, the width of the mat 20 is set to be narrow so as to prevent the infant from turning over, and as a result, the plane of the exchange base body 10 for placing the luggage without increasing the overall dimensions as compared with the conventional product. Only the region A (article placement portion) can be further enlarged.

  Further, since the left and right first peripheral wall portions 25a adjacent to the planar area A of the exchange base body 10 have a certain height, even if the guardian puts a load on the planar area A, the mat 20 The baggage is prevented from falling over to sleeping infants. Further, since the second peripheral wall portion 25b on the head side is formed to be the highest, it is possible to prevent the infant from moving upward while kicking the mat surface 21 while the infant is sleeping. Furthermore, since the fourth peripheral wall portion 25d on the leg side is formed lower, the infant can be prevented from falling and the infant can be seated along the inclined surface 25e of the peripheral wall 25. Etc. can be easily performed.

  The mat 20 has a protrusion 26 extending laterally. Note that “lateral” refers to a direction parallel to the mat surface 21. Further, “extending laterally” does not necessarily have to be parallel in the strict sense along the mat surface 21, but extends diagonally downward so as to include a component in the lateral direction. Is also included. Specifically, in the present embodiment, a total of four protrusions 26 extend from the outer peripheral surface of each of the left and right first peripheral wall portions 25a of the mat 20 outward in the left-right direction, that is, laterally. . Each protrusion 26 is a flat member as a whole parallel to the mat surface 21.

  FIG. 7 is a perspective view of the upper first housing 12 attached to the lower housing 11. The upper first housing 12 and the upper second housing 13 will be described with reference to FIG. 6 together with FIG.

  Referring to FIG. 7, the upper first housing 12 has two recesses 14 as receiving portions that receive the protrusions 26 at positions corresponding to the two protrusions 26 on one of the left and right sides of the mat 20. Further, as shown in FIG. 6, the upper second housing 13 also receives the protrusions 26 at positions corresponding to the two protrusions 26 on the left and right sides of the mat 20, similarly to the upper first housing 12. As shown in FIG. The peripheral portions of the upper first housing 12 and the upper second housing 13 facing the mat 20 are formed to be complementary to the outer shapes of the left and right first peripheral wall portions 25 a of the mat 20.

  Further, as shown in FIG. 7, curved groove portions 15 are formed at both ends of the surface of the upper first housing 12 facing the mat 20 and in the vicinity of the peripheral edge portion. Although not shown, a similar groove is formed in a corresponding portion 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 so that four thin wall corners 27 (FIGS. 4 and 6) of the mat 20 are fitted.

  FIG. 8 is a perspective view showing the engagement between the protrusion 26 and the recess 14, and FIG. 9 is a cross-sectional view showing the engagement between the protrusion 26 and the recess 14. FIG. 8 shows the engagement between the recess 14 of the upper second housing 13 and the protrusion 26 of the mat 20, but the engagement with the recess 14 of the upper first housing 12 is the same. The protrusions 26 of the mat 20 are arranged below the recess 14, that is, on the lower housing 11 side in a state where the mat 20 is attached to the exchange base body 10. Therefore, the protrusion 26 of the mat 20 and the upper first housing 12 and the upper second housing 13, that is, the exchange table main body 10, with respect to the movement in the direction in which the mat 20 is detached from the exchange table main body 10 (upward in FIG. 9). The concave portion 14 is engaged and the mat 20 is prevented from coming off. Further, since the recess 14 is defined by the partition wall 14a (FIG. 8) surrounding the three sides, the movement of the projection 26 is restricted.

  FIG. 10 is a view showing how to attach the mat 20. The mat 20 is attached when the diaper changing table 1 is changed to an up / down change or when the cushion member of the mat 20 becomes dirty or torn and is replaced with a new mat 20. The replacement work of the mat 20 is performed in a state where the exchange table main body 10 is in a horizontal state, that is, in a use state of the diaper changing table 1.

  First, from the state of the lower housing 11 and the upper first housing 12 shown in FIG. 7, the operator applies the two protrusions 26 on one side of the mat 20 facing the upper first housing 12 to the corresponding upper first housing 12. It arrange | positions in the recessed part 14 vicinity. At this time, the mat 20 finally engages the protrusions 26 and the recesses 14 while fitting the corners 27 of the mat 20 into the grooves 15 of the upper first housing 12. The state is rotated around an axis parallel to the rotation axis, that is, the state is inclined with respect to the exchange base body 10. In this state, the upper second housing 13 is prepared, and the two protrusions 26 on the other side of the mat 20 are engaged with the corresponding recesses 14 of the upper second housing 13, and the corner portion 27 of the mat 20 is moved to the upper second. It is attached so as to be fitted into the groove 15 of the housing 13. This state is shown in FIG.

  Note that FIG. 8 described above shows the upper second housing 13 and the mat 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 portion 27 of the mat 20 is fitted to the groove portion 15 of the upper first housing 12, and the upper second housing 13 and the mat are fitted. 20 is arranged in the lower housing 11. Finally, the upper second housing 13 is fixed by coupling means such as screwing, and the attachment is completed. The mat 20 is engaged with the upper first housing 12 and the upper second housing 13, and is sandwiched between the upper first housing 12 and the upper second housing 13, so that a coupling means for fixing is provided. There is no need to use.

  In the above-described mounting procedure, the upper first housing 12 starts from a state in which the upper first housing 12 is previously attached to the lower housing 11 (FIG. 7), and one side of the mat 20 with the upper second housing 13 integrally attached is connected to the upper first housing 12. The attachment was completed while rotating while abutting on the housing 1 side. However, for example, when working by a plurality of people, the upper first housing 12, the mat 20, and the upper second housing 13 that are integrally attached in advance are covered with the lower housing 11 from above. Attachment may be performed. That is, in the upper first housing 12, the mat 20, and the upper second housing 13 that are integrally attached in advance, the corner portion 27 of the mat 20 is fitted into the groove portion 15 of the upper first housing 12 and the upper second housing 13. In addition, since the protrusions 26 of the mat 20 and the recesses 14 of the upper first housing 12 and the upper second housing 13 are engaged, attachment can be easily performed.

  As shown in FIG. 6, the outer shape of the mat 20 including the four protrusions 26 is point-symmetric about the center point C. Therefore, even if the mat 20 is rotated 180 degrees around the center point C in FIG. 6, that is, even if the mat 20 is arranged so that the babies laid upside down are turned upside down, So that it can be engaged. When the arrangement of the mat 20 is changed, the mat 20 is removed from the exchange base body 10 by performing operations in the reverse order to the above-described attachment.

  Note that the mat 20 replaces the recess 14 that is the engaging portion of the upper first housing 12 and the upper second housing 13, that is, the recess 14 of the exchange base body 10 and the protrusion 26 of the mat 20 that is the engaged portion. As long as they can be engaged with each other in the direction away from the main body 10, each may have any shape. For example, the protrusion 26 may be a columnar shape instead of a flat plate shape. Further, the recess 14 as the receiving portion does not need to be defined in the partition wall 14a, but may be a flat portion, and the hole 16 into which the protrusion 26 is inserted as shown in FIG. It may be. Further, a protrusion that extends laterally may be provided on the exchange base body 10 side, and a recess or a hole that can be engaged with the protrusion may be provided on the mat 20 side.

  According to the present invention, it is not necessary to screw the mat 20 into the exchange base body 10, and it is only necessary to screw the upper first housing 12 and the upper second housing 13 together. Is possible. Therefore, the workability at the time of changing the arrangement of the mat 20 or at the time of replacement is improved, and the smooth construction and subsequent maintenance of the diaper changing table 1 can be performed. Further, the mat 20 is not snap-fitted with a large elastic deformation to the member, but the mat 20 is prevented from being detached from the exchange base body 10 due to the engagement of the projection 26 and the recess 14 with high rigidity. As a result, an extremely durable mounting mechanism can be realized. Further, the cushion member of the mat 20 and the other members such as the upper first housing 12 do not interfere with each other due to the mounting structure of the mat 20, so that the cushion member is not damaged.
