  The main problem to be solved by the present invention is that a joint device that maintains the combined state of members of this type and a mounting structure for an apron for a bath that includes the joint device are used when the members are brought together. The point is that the position of the engaging part of the male part engaged with the part can be easily adjusted with a simple structure.

In order to achieve the above object, in the present invention, the joint device is a joint device that maintains the combined state of the other member that is combined with the one member against the one member,
A male part that is attached to one of the one member and the other member, and is provided with a bolt that can be screwed back and forth so that a shaft portion of the bolt is arranged in a direction crossing the butting direction,
It was attached to the other of the one member and the other member, and consisted of a female part provided with an elastic holding part that received the shaft part of the bolt of the male part in a fitting manner by the butting.

  According to this configuration, the bolt of the male part can adjust the position of the head by screwing back and forth, so that the screw screw back and forth absorbs errors and deviations in the axial direction of the bolt, and the one member and the other Fastening with the member can be made.

The female part is
An attachment base to the other of the one member and the other member;
With respect to this mounting base, the direction along the X axis located on a virtual plane perpendicular to the axis of the bolt of the male part, and the Y axis located on this virtual plane and perpendicular to the X axis It is composed of a slider that is slidably combined in each direction,
This slider may be provided with an elastic holding portion.

  In this case, the bolt of the male part can adjust the position of its head by screwing back and forth, and by moving the slider of the female part to the X axis line and the Y axis line on a virtual plane perpendicular to the axis line of this bolt. Since the elastic holding portion can be moved and adjusted along the line, the one member and the other member can be fastened together by absorbing errors and deviations by adjusting the movement of the engaging part of the male part and the female part.

The elastic holding part is composed of a pair of elastic pieces that receive the shaft part of the bolt of the male part between the inner surfaces facing each other,
One arm of a metal reinforcing body bent in a channel shape is positioned outside one of the pair of elastic pieces, and the other arm of the reinforcing body is positioned outside the other of the pair of elastic pieces. A reinforcing body may be attached to the elastic holding portion.

  In this case, the rigidity of the elastic piece can be increased without excessively increasing the thickness of the elastic piece constituting the elastic holding portion.

Moreover, in order to achieve the said subject, in this invention, while using the apron attachment structure for bathtubs, the said joint tool is used 1 or 2 or more,
Male parts of the joint tool on the back of the bathtub apron
The female part of the joint tool is provided on the floor pan side where the lower side of the apron is abutted.

  Such an apron is attached so as to cover the side surface under the top edge of the bathtub. However, it is difficult to align the engagement portion between the apron and the floor pan with high accuracy. According to the present invention, the position of the head of the male part bolt can be adjusted by screwing back and forth. Further, in the case of the joint device having the elastic holding part of the female part on the slider, a virtual plane perpendicular to the axis of the bolt is used. Since the elastic holding part can be moved and adjusted along the upper X-axis and Y-axis, the apron and floor pan can be fastened by absorbing errors and misalignments by adjusting the moving parts of the male and female parts. Can be combined.

  According to the present invention, the position of the bolt that becomes the engaged part of the male part that is engaged with the female part when the other member is abutted can be easily adjusted by screwing back and forth between the one member and the other member. The resulting dimensional error in the axial direction of the bolt can be sufficiently tolerated with a simple structure.

  The best mode for carrying out the present invention will be described below with reference to FIGS.

  Here, FIGS. 1 and 2 show the male part 1 constituting the joint device according to the embodiment, FIGS. 3 to 7 show the first configuration example of the female part 2 constituting the joint tool, FIG. 10 and 21 show a second configuration example of the female part 2 constituting the joint tool, FIGS. 11 to 14 show the mounting base 22 constituting the second configuration example, and FIGS. The slider 23 which comprises this 2nd structural example is each shown. (In FIG. 2, the bolt 11 and the nut 105 are not in cross section.)

  The joint device according to this embodiment maintains the combined state of the other member 4 that is brought into contact with the one member 3 and combined with the one member 3.

  For example, such a joint tool is used so as to maintain this fitting state when the decorative panel is combined so as to be put in a portion to be covered of a member covered by the decorative panel.

  Such a joint tool includes a male part 1 and a female part 2. Then, when the other member 4 is combined with the one member 3 in a butting manner, the male part 1 is engaged with the female part 2 and the combined state is maintained. As will be described later, a portion (a bolt 11 described later) engaged with the female part 2 in the male part 1 can be moved and adjusted along the Z-axis line in FIG. Further, in the second configuration example of the joint tool, a portion (elastic holding portion 20 described later) that engages with the male part 1 in the female part 2 moves along the X axis and the Y axis in FIGS. 8 and 9. Adjustable. Thus, in particular, such a joint tool is difficult to form the one member 3 and the other member 4 with a small dimensional error. For this reason, in the combination of both, the engaging position of the female part 2 and the male part 1 is set up and down. Furthermore, it can be used effectively when it is necessary to adjust the front, rear, left and right.

On the other hand, the attachment structure of the apron 40 for a bathtub according to this embodiment uses one or two or more such joint tools,
The male part 1 of the joint tool is attached to the back surface 40a of the apron 40 for the bathtub.
The female part 2 of the joint tool is provided on the floor pan 30 side to which the lower side of the apron 40 is abutted.

  The apron 40 has a panel shape formed from a synthetic resin or the like, and typically, the apron 40 is slanted, and the apron 40 has an arc shape in which the upper end of the apron 40 is formed on the top end side of the bathtub and the lower side is a curved inner side. After being inserted into a flange (not shown) from below, the lower end of the apron 40 is rotated from the washing place side 5 to the position where the lower end of the apron 40 is brought into contact with the abutting portion 30a of the floor pan 30. It is used so that the side surface of 5 bathtubs may be covered from the washroom side 5 in a vertical state. (Fig. 8)

  In the illustrated example, the position of the apron 40 in the middle in the left-right direction is fastened to the floor pan 30 with a joint tool according to a second configuration example described later. In the illustrated example, the female part 2 is attached to the upper surface of the floor pan 30 in the vicinity of the abutting part 30a so that the entrance 201 of the elastic holding part 20 faces the washing place side 5, while the male part 1 is attached to the apron. The bolt 11 is attached to the reinforcing member 40c so as to protrude downward from the lower surface of the block-like reinforcing member 40c provided on the back surface 40a on the lower end 40b side of the block 40 with a space between the lower end 40b. It has been.

  The apron 40 is attached so as to cover the side surface under the top of the bathtub, but it is difficult to align the apron 40 and the floor pan 30 with high accuracy. The bolt 11 of the male part 1 can adjust the position of the head 111 by screwing back and forth, and if the elastic holding part 20 of the female part 2 is provided on the slider 23 described later (second configuration example) The elastic holding portion 20 can be moved and adjusted along the X-axis and Y-axis on a virtual plane orthogonal to the 11 axis (Z-axis), and errors and deviations can be reduced by the three-dimensional movement adjustment of the engaging portion. The apron 40 after absorption and the floor pan 30 can be fastened together. In the illustrated example, the bolt 11 of the male part 1 is moved and adjusted in the vertical direction, and the elastic holding portion 20 of the female part 2 is moved and adjusted in the front-rear direction (the approaching and separating direction with respect to the side surface of the bathtub) and the left and right direction (the lateral direction of the side surface of the bathtub). It can be done. In addition, what is shown with the code | symbol 6 in a figure is the side surface side of the bathtub which is not shown in figure.

  The male part 1 is composed of a disc-like body 10 having both sides having a substantially rectangular shape and the bolt 11. (FIGS. 1 and 2) A rising portion 101 is formed on one side of the disk-shaped body 10 along the length direction. In the example shown, the male part 1 The wide surface is brought into close contact with the lower surface of the reinforcing member 40c so that the portion 101 is hooked on the corner 40d between the lower surface of the reinforcing member 40c and the side surface of the reinforcing member 40c directed to the side surface of the bathtub. The apron 40 is attached to the back surface 40a side. A through hole 102 opened on each of the wide surfaces is formed at a position approximately in the middle of the length of the plate-like body 10, and a through hole 103 for a screw N is formed on both sides of the through hole 102. Is formed. The male part 1 is fixed to the reinforcing member 40c by a screw N inserted into the through hole 103 from below and screwed to the lower surface of the reinforcing member 40c. In the illustrated example, the through-hole 103 is configured to have a hole diameter larger than the diameter of the screw N in the width direction of the plate-like body 10, and the fixing position of the male part 1 to the reinforcing member 40c, that is, In this case, the protruding position of the bolt 11 can be finely adjusted here.

  In the example shown in the figure, the outer diameter of the hexagonal nut 105 that is opened at the end surface of the narrow end surface along the length direction of the disc-like body 10 and is screwed to the bolt 11 is substantially the same. An introduction hole 104 having the same hole width and communicating with the through hole 102 inside the disk-shaped body 10 is formed. In the illustrated example, the nut 105 is inserted into the introduction hole 104 so that the female screw hole of the nut 105 communicates with the through hole 102. The rear portion 104 a of the introduction hole 104 has a shape that follows the outer end surfaces of two nuts sandwiching one corner of the nut 105, and the nut 105 does not rotate in the introduction hole 104.

  The bolt 11 is screwed to the nut 105 through the through hole 102 of the disk-shaped body 10 to constitute the male part 1 together with the disk-shaped body 10. In the illustrated example, the bolt 11 is arranged so that the shaft portion 112 of the bolt 11 protrudes downward from the plate-like body 10 with the head portion 111 facing down. The position of the head 111 of the bolt 11 is finely adjusted by screwing the bolt 11 back and forth.

  Unlike the illustrated example, the nut 105 can be provided with the nut 105 as an insert when the plate-like body 10 constituting the male part 1 is plastic-molded.

(Female part 2 / first configuration example)
3-7 has shown one of the structural examples of the female part 2 provided with the elastic holding part 20 with respect to the volt | bolt 11 of the said male part 1. FIG.

  In this example, the female part 2 includes a substrate 21 having a substantially rectangular plate shape. In this example, a pair of through holes 211, 211 formed at intervals in the width direction of the substrate 21 are formed in a penetrating state at both ends of the substrate 21, and the female part 2 is inserted into the through holes 211. The screw N inserted from above is screwed to the floor pan 30 side to be fixed to the floor pan 30 side. The through-hole 211 also has an oval contour in which the hole diameter is larger than the diameter of the screw N in the length direction of the substrate 21, and the fixing position of the female part 2 to the floor pan 30, that is, the elastic holding The position of the entrance 201 of the holding part 20 can be finely adjusted here.

  The elastic holding portion 20 is formed on one surface side of the substrate 21 so as to protrude from a position approximately in the middle of the length direction, and is provided so that the entrance 201 faces the one end side of the substrate 21.

  In the illustrated example, the elastic holding portion 20 is mainly configured by a pair of side plates 202 and 202 that receive the bolt 11 therebetween. Between the upper ends of the pair of side plates 202, 202, an abutting portion 203 of the bolt 11 is formed at a distance from the entrance 201 side, and the pair of side plates 202, The bolt 11 is fitted between the entrances 201 between 202. A slope that is inclined toward the entrance 201 side of the pair of side plates 202 and 202 so as to increase the distance between the side plate 202 and the other side plate 202 as the distance from the formation side of the abutting portion 203 extends in the vertical direction of the side plate 202. A surface 204 is formed, and by this inclination, the bolt 11 is guided and introduced to the back side of the elastic holding portion 20, that is, the abutting portion 203 side.

  On the upper end side of the pair of side plates 202, 202, two lateral grooves 205a along the width direction of the side plate 202 are provided at intervals in the vertical direction of the side plate 202, and the two lateral grooves 205a are provided. 205a, the groove ends on the inlet 201 side are connected to each other by a vertical dividing groove 205b extending in the vertical direction of the side plate 202, and the horizontal dividing groove 205a and the vertical dividing groove 205b are connected to the upper ends of the pair of side plates 202, 202. Elastic pieces 205 each having a base of the abutting portion 203 are formed. On the inner side of the distal end side of the pair of elastic pieces 205, 205, a hooking convex portion 205c protruding toward the other elastic piece 205 is formed. The distance between the pair of engaging projections 205 c and 205 c is smaller than the diameter of the shaft portion 112 of the bolt 11. In addition, the hooking convex portion 205c is inclined at the side surface 205e on the entrance 201 side and the abutting portion 203 side with the top portion 205d interposed therebetween.

  In the illustrated example, when the apron 40 which is the other member 4 is combined with the floor pan 30 which is the one member 3, the shaft portion 112 of the bolt 11 of the male part 1 is connected to the entrance 201 of the elastic holding portion 20. From the pair of elastic pieces 205 and 205 to the engaging projections 205c, the interval between the engaging projections 205c is temporarily expanded outwardly by elastically deforming the elastic pieces 205, and then contacted with the engaging projections 205c. The elastic piece 205 is elastically restored at a position where the shaft portion 112 of the bolt 11 enters between the portion 203 and the bolt 11 is prevented from coming out of the elastic holding portion 20. Due to the inclination of the side surface 205e of the hooking projection 205c, such elastic deformation is made smooth, and when the apron 40 combined as described above is once pulled with a force that is in the direction of removing, the elastic piece 205 is removed again. The bolt 11 is removed from the elastic holding portion 20 by being elastically deformed in the direction so that it can be removed.

  Further, in the illustrated example, a rib 206 is formed along the width direction of the side plate 202 on the inner surface side of the pair of side plates 202 and 202 and below the formation position of the elastic piece 205. The dimension between the rib 206 formed on one side plate 202 and the rib 206 formed on the other side plate 202 is substantially equal to the diameter of the shaft portion 112 of the bolt 11, and from the diameter of the head portion 111 of the bolt 11. Is also getting smaller. Further, below the rib 206, the distance between the inner surfaces of the pair of side plates 202 and 202 is large enough to accommodate the head 111 of the bolt 11. Accordingly, in the illustrated example, in the combined state of the apron 40, the head 111 of the bolt 11 received from the entrance 201 is hooked on the rib 206, and the upward movement of the bolt 11, that is, the upward movement of the apron 40 is also performed. It regulates via the female part 2.

In this example, a space 223 (described later) is provided in the mounting base 22, and the elastic holding portion 20 of the slider 23 is sized to move within the space 223. A base 231 (to be described later) of the slider 23 is sandwiched between the mounting base 22 and the one member 3 in a state where the elastic holding portion 20 is protruded from the space 223 of the mounting base 22 attached. The slider 23 is combined.

  The base has a length and a width in a plan view, has a mounting portion 221 provided with through holes 221a of screws N on both sides of the length side, and a connecting piece 222 between the pair of mounting portions 221 and 221. It is the thing of the aspect connected by. A hook portion 221b protruding downward across the side portion is formed on the side portion of the attachment portion 221 facing the washing place side 5, and the base hooks the hook portion 221b on the butting portion 30a of the floor pan 30, and The lower surface of the floor pan 30 is fixed to the upper surface of the floor pan 30 by a screw N screwed to the floor pan 30 through the through hole 221a. The connecting piece 222 includes an outer side 222 a that is continuous with a side portion that faces the side surface 6 of the bathtub in the attachment portion 221 and an inner side 222 b that is perpendicular to the side portion that faces the other attachment portion 221 in the attachment portion 221. It is configured to have. The base is provided with a space 223 opened to the washing area 5 at the center by the pair of attachment parts 221 and 221 and the connecting piece 222.

  On the other hand, the slider 23 includes a base portion 231 having a substantially rectangular plate shape. In the illustrated example, the elastic holding portion 20 is formed so as to protrude from the upper surface of the base portion 231. The elastic holding part 20 has substantially the same configuration as the elastic holding part 20 of the first configuration example. (Therefore, the details of the configuration of the elastic holding portion 20 of the second configuration example are given the same reference numerals as those assigned to the respective portions of the elastic holding portion 20 of the first configuration example in the drawing showing this. The description is omitted.) Then, the lower ends of the pair of side plates 202, 202 constituting the elastic holding portion 20 are integrally connected to the upper surface of the base portion 231. The elastic holding portion 20 is provided in a state where the entrance 201 is directed to one side of the side of the base portion 231 in the length direction at a position in the middle of the base portion 231 in the longitudinal direction.

  On the back side of the mounting base 22, each of the pair of mounting portions 221, 221 is provided with a recess 221 c that leads to the space 223, respectively, in contact with the space 223. The depth of the recess 221 c is substantially equal to the thickness of the base 231 of the slider 23. In addition, the dimension a between the pair of wall portions 221d and 221d along the length direction of the mounting base 22 in the recess 221c is larger than the width a ′ of the base portion 231 and is on one side across the space 223. The dimension b between the wall portion 221e along the width direction of the mounting base 22 in the recess 221c and the wall portion 221e along the width direction of the mounting base 22 in the recess 221c on the other side across the space 223 is the base portion It is larger than the length b ′ of H.231. At the same time, the dimension c of the void 223 in the direction along the length direction of the mounting base 22 is larger than the dimension c ′ of the elastic holding part 20 in this direction and smaller than the length of the base 231. Yes.

  In this example, the elastic holding portion 20 of the slider 23 protrudes from the space 223 of the mounting base 22, and the upper surface of the base portion 231 of the slider 23 is in contact with the top surface 221 f of the recess 221 c of the mounting base 22. When the slider 23 is combined with the mounting base 22, the top surface 221f of the recess 221c with one side sandwiching the elastic holding portion 20 in the base portion 231 of the slider 23 and the wall portion 221d on the hook portion 221b side are always present. The other side of the base portion 231 of the slider 23 sandwiching the elastic holding portion 20 is caught by the top surface 221f of the recess 221c on this side and the wall portion 221d on the hook portion 221b side.
