[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a clip and bathtub apron mounting structure for engaging two members with each other.
[0002]
[Prior art]
As shown in FIG. 5, in the bath unit 100, a bathtub 104 is placed on the floor pan 102, and the wall surface 104 </ b> A of the bathtub 104 on the washing area pan 106 side has a substantially rectangular apron for makeup. 108 is covered.
[0003]
Between the floor pan 102 and the washing place pan 106, a dam portion 110 is projected in parallel with the bathtub 104. The upper surface of the dam portion 110 is horizontal, and the female member 112 is screwed. The female member 112 is provided with an engaging portion 114 formed in a substantially U shape, and can be elastically deformed.
[0004]
On the other hand, on the lower side of the apron 108, a lower flange portion 116 projects from the back surface, and a male member 118 that can engage with the female member 112 is screwed to the lower flange portion 116. From the standing wall 118 </ b> A of the male member 118 disposed in a state orthogonal to the lower flange portion 116, an engagement piece 120 protrudes substantially parallel to the protruding direction of the lower flange portion 116.
[0005]
The engagement piece 120 is thin on the distal end side and the base side, and the thickness of the central part and the base part of the engagement piece 120 is maximum. Further, the thickness of the central portion of the engagement piece 120 is larger than the separation distance of the end portion 114 </ b> A of the engagement portion 114.
[0006]
Thus, before the engagement piece 120 moves to the back of the engagement portion 114, the engagement piece 120 abuts on the end portion 114A. In this state, the engagement piece 120 is pressed to expand the end portion 114A. 120 can move to the back of the engaging portion 114. When the engagement piece 120 moves to the back of the engagement portion 114, the end portion 114A of the engagement portion 114 is restored, the engagement piece 120 is prevented from coming off, and the male member 118 is engaged with the female member 112. It has become.
[0007]
By the way, an upper flange portion 112 bent in a step shape is formed on the upper side of the apron 108, and when the wall surface 104A of the bathtub 104 is covered with the apron 108, the upper flange portion 112 is covered with the opening edge portion 104B of the bathtub 104. In this state, the lower flange portion 116 side is rotated about the upper flange portion 112 side as a fulcrum, and the lower flange portion 116 is fixed to the dam portion 110 via the male member 118 and the female member 112. When the engagement piece 120 of the member 118 is moved from the state of FIG. 6A to the back of the engagement portion 114 of the female member 112, the lower flange portion 116 side is rotated with the upper flange portion 112 side of the apron 108 as a fulcrum. In order to move it, the movement locus of the engagement piece 120 also draws an arc.
[0008]
For this reason, the vertical position of the engagement piece 120 with respect to the engagement portion 114 slightly lowers from the state in contact with the end portion 114A of the engagement portion 114 until it moves to the back of the engagement portion 114. When the engagement piece 120 is moved to the back of the engagement portion 114, there is a fear that an excessive load is applied to the engagement piece 120. As shown in FIG. 120 may be damaged.
[0009]

For this reason, the other member can be relatively moved in the vertical direction and the horizontal direction with respect to the female member via the slide member and the engagement piece, so that the vertical direction and the horizontal direction of one member and the other member can be moved. Can be absorbed.
[0016]
In the invention according to claim 2 , the one end side of the apron is hooked on the edge of the bathtub and the other end side of the apron is rotated to cover the washing wall side peripheral wall of the bathtub placed on the floor pan. In the apron mounting structure, a flange portion protrudes from the back surface of the apron, while a dam portion is provided between the floor pan and the wash basin in parallel to the peripheral wall of the bathtub. A clip is fixed to one of the flange part and the dam part, and can be engaged with an engagement piece fixed to the other of the flange part and the dam part.
[0017]
For example, a clip is fixed to the weir part and an engagement piece is provided on the flange part. Thereby, one end side of the apron is hooked on the edge of the bathtub, the other end side of the apron is rotated, and the engaging piece is engaged with the engaging portion constituting the clip, and the engaging piece and the engaging portion are Then, the washing area side of the bathtub is covered with an apron.
[0018]
Here, one end side of the apron is hooked on the edge of the bathtub and the other end side of the apron is rotated, so that the engagement piece moves in a circular arc around the one end side of the apron, In the engagement process, vertical displacement occurs between the engagement piece and the engagement portion, but the displacement can be absorbed by sliding the slide member downward.
[0019]
Therefore, according to the vertical position of the engagement piece with respect to the engagement portion, the engagement portion is moved via the slide member, so that there is no risk of damage to the engagement piece due to displacement of the engagement portion. Moreover, when attaching an apron to a bathtub, smooth attachment is attained.
[0020]
DETAILED DESCRIPTION OF THE INVENTION

[0033]
The width of the engaging portion 52 in the left-right direction is longer than the width of the engaging piece 34 in the left-right direction. Therefore, the engagement piece 34 is slidable in the left-right direction within the engagement portion 52 in a state where the engagement piece 34 is engaged with the engagement portion 52.
[0034]
Next, the bathtub apron mounting structure and its operation according to this embodiment will be described.
[0035]
As shown in FIG. 2, the peripheral wall 66A of the bathtub 66 arranged on the floor pan 64 of the bath unit 62 on the washing place pan 68 side is covered with a cosmetic apron 72 formed in a substantially rectangular shape. Between the floor pan 64 and the wash basin pan 68, a weir 70 having a substantially U-shaped cross section is provided in parallel with the bathtub 66, and the upper surface 70A of the weir 70 is horizontal. The female member 12 is fixed to the upper surface 70 </ b> A of the dam portion 70.
[0036]
Here, the engaging portion 52 of the slide member 14 is press-fitted into the rectangular hole 46 formed in the female member 12 in advance, and the peripheral portion of the female member 12 is formed by the claw portion 58 (see FIG. 1) and the flat plate portion 48. The slide member 14 is slidably engaged with the rectangular hole 46.
[0037]
On the other hand, as shown in FIG. 3A, a screw hole 71 is formed at a predetermined position on the upper surface 70A of the dam portion 70, and the bottom portion of the female member 12 is engaged with the slide member 14 engaged. The bottom portion 38 of the female member 12 is brought into contact with the upper surface 70A of the dam portion 70, and the female member 12 is fastened to the dam portion 70 by the fixing screw 44.
[0038]
By the way, a lower flange portion 74 projects from the back side of the apron 72 below the apron 72, and the male member 16 that can be engaged with the female member 12 can be fixed to the lower flange portion 74. .
[0039]
A screw hole 31 is formed at a predetermined position in the lower flange portion 74, and the bottom portion 38 of the male member 16 is aligned with the through hole 32 formed in the bottom portion 38 of the male member 16. The male member 16 is fastened to the lower flange portion 74 by the fixing screw 33.
[0040]
On the other hand, an upper flange portion 76 bent in a step shape is formed on the upper side of the apron 72, and the upper flange portion 76 can be hooked on the opening edge portion 66 </ b> B of the bathtub 66. When the upper flange portion 76 is hooked on the opening edge portion 66B of the bathtub 66 and the upper flange portion 76 side is turned as a fulcrum, the lower flange portion 74 side is rotated, as shown in FIG. The front end of the engagement piece 34 passes through the inlet 50 of the slide member 14 and comes into contact with the front end surface 56 </ b> A of the side wall 56 of the engagement portion 52.
[0041]
In this state, the apron 72 is pressed, the front end surface 56A of the side wall 56 is expanded by the front end portion of the engagement piece 34, and the central portion of the engagement piece 34 is passed through, thereby engaging the engagement piece 34 with the engagement portion. The apron 72 rotates the lower flange portion 74 side with the upper flange portion 76 side as a fulcrum, so that the engagement piece 34 moves while drawing an arc. Therefore, in the process in which the engagement piece 34 moves to the back of the engagement portion 52, the engagement piece 34 slightly moves downward.
[0042]
Therefore, the slide member 14 is slid downward in the rectangular hole 46 in accordance with the downward movement amount of the engagement piece 34. Thereby, as shown in FIG. 3B, the engagement piece 34 can be smoothly moved to the back of the engagement portion 52.
[0043]
When the engagement piece 34 moves to the back of the engagement portion 52, the front end surfaces 54 </ b> A and 56 </ b> A of the engagement portion 52 are restored, the engagement piece 34 is prevented from coming off, and the male member 16 is engaged with the female member 12. . Thereby, the peripheral wall 66 </ b> A of the bathtub 66 can be covered with the apron 72 via the male member 16 and the female member 12.
[0044]
With the above-described configuration, even when a positional deviation occurs in the vertical direction between the female member 12 and the engagement piece 34, the female member 12 and the engagement piece 34 are engaged with each other via the slide member 14. The slide member 14 can be slid to absorb the positional deviation. For this reason, since the engagement piece 34 can be engaged with the engagement portion 52 without applying an excessive load to the engagement piece 34, there is no fear of the engagement piece 34 being damaged by the excessive engagement. .
[0045]
Further, by moving the engagement portion 52 via the slide member 14 in accordance with the vertical position of the engagement piece 34 with respect to the engagement portion 52, smooth attachment is possible when the apron 72 is attached to the bathtub 66. It becomes.
[0046]
Here, since the outer dimension of the flat plate portion 48 of the slide member 14 is larger than that of the rectangular hole 46, the flat plate portion 48 can come into contact with the peripheral edge portion of the rectangular hole 46. Therefore, by sliding the slide member 14 with the flat plate portion 48 and the claw portion 58 (see FIG. 1) sandwiching the peripheral edge portion of the rectangular hole 46, the play of the slide member 14 can be reduced. The slide member 14 can be smoothly slid.
[0047]
Even when the engagement piece 34 and the engagement portion 52 are displaced in the left-right direction, the width of the engagement portion 52 in the left-right direction is made longer than the width of the engagement piece 34 in the left-right direction. Therefore, when the engagement piece 34 is engaged with the engagement portion 52 or after the engagement piece 34 is engaged with the engagement portion 52, the engagement portion 52 and the engagement piece 34 are relatively moved. It is also possible to absorb the misalignment between the peripheral wall 66A of the bathtub 66 and the apron 72 in the left-right direction.
[0048]
Further, even when the engagement piece 34 and the engagement portion 52 are displaced in the front-rear direction, the long hole portion 42 is provided in the bottom portion 38 of the female member 12. The position shift in the front-rear direction between the engagement piece 34 and the engagement portion 52 can be absorbed by moving at 70A.
[0049]
Here, the female member 12 is fixed to the dam portion 70 and the male member 16 is fixed to the lower flange portion 74 side of the apron 72, but the male member 16 is fixed to the dam portion 70 and the bottom of the apron 72. The female member 12 may be fixed to the flange portion 74 side.
[0050]
Further, as shown in FIG. 4, the apron 72 is provided with a holder piece 80 that extends parallel to the lower flange portion 74 and extends longer than the lower flange portion 74, and this holder piece 80 is brought into contact with the upper surface 70A of the dam portion 70. Thus, the weight of the apron 72 may be received.
[0051]
The holder piece 80 is a height where a gap is generated between the lower surface of the holder piece 80 and the upper surface 70A of the dam portion 70 in a state where the apron 72 covers the peripheral wall 66A (see FIG. 2) of the bathtub 66 (see FIG. 2). In this case, after the male member 16 is engaged with the female member 12 and the apron 72 is positioned in the vertical direction, a gap formed between the lower surface of the holder piece 80 and the upper surface of the dam portion 70 is formed. The spacer 82 is inserted to adjust the height.
[0052]
Thereby, the weight of the apron 72 applied to the engagement piece 34 can be received by the holder piece 80, deformation of the engagement piece 34 due to creep and the like can be prevented, and the life of the clip 10 can be extended.
[0053]
Although the slide member 14 is slid in the vertical direction of the female member 12, depending on the method of attaching the apron 72, the slide member 14 may be slid in the left-right direction. It is not restricted to the method of attaching by rotating the end side. Furthermore, although clip 10 was used for attachment of the bathtub apron, it is not restricted to this, What is necessary is just a clip used in order to engage two members mutually.
[0054]
【The invention's effect】
Since the present invention is configured as described above, in the first aspect of the present invention, even if a positional deviation occurs between the female member and the engaging piece, the female member and the engaging piece are engaged via the slide member. By combining, the slide member can be slid to absorb the positional deviation, and the engagement piece can be engaged with the engagement portion without applying an excessive load to the engagement piece. Therefore, there is no fear of breakage of the engagement piece due to excessive engagement.
[0055]
In addition, by holding the peripheral edge of the rectangular hole between the flat plate portion and the claw portion and engaging the slide member with the rectangular hole, when the slide member is slid, the play of the slide member can be reduced, The slide member can be smoothly slid.
[0056]
Furthermore, since the other member can be moved relative to the female member in the vertical direction and the horizontal direction via the slide member and the engagement piece, the vertical direction and the horizontal direction of one member and the other member can be moved. Misalignment can be absorbed.
[0057]
According to the second aspect of the present invention, the engagement piece is moved by the displacement of the engagement portion by moving the engagement portion via the slide member in accordance with the vertical position of the engagement piece with respect to the engagement portion. In addition, there is no fear of breakage, and smooth attachment is possible when the apron is attached to the bathtub.
