  Further, as shown in FIG. 11, the first side piece 41 is provided with a position adjusting portion mounting hole 41b. A female screw portion (not shown) is provided in the position adjusting portion mounting hole 41b. The female screw portion may be directly formed on the inner surface of the position adjusting portion mounting hole 41b, or may be provided with a separate female screw member (not shown). The male screw portion 70a of the pressing portion mounting shaft 70 is screwed into the female screw portion. Then, the handle knob 75 is rotated, and the rotational force is transmitted to the pressing portion mounting shaft 70 with a predetermined force or less, so that the pressing portion mounting shaft 70 moves back and forth with respect to the first side piece 41. The pressing portion 2 is attached to the pressing portion mounting portion 74 formed on the end surface of the other end portion of the pressing portion mounting shaft 70. For this reason, the pressing portion 2 moves back and forth with respect to the first side piece 41 by moving the pressing portion mounting shaft 70 back and forth with respect to the first side piece 41.

  The pressing portion 2 is supported by the pressing portion mounting portion 74 so that the posture, that is, the direction is variable. In this case, for example, the pressing portion 2 has a ball portion, and the pressing portion mounting portion 74 has a receiving portion for receiving the spherical portion, and the spherical portion is received by the receiving portion, so that the pressing portion 2 and the pressing portion are attached. The part 74 is connected. At this time, the pressing portion 2 can rotate around an axis in a three-dimensional arbitrary direction with respect to the pressing portion mounting portion 74 (that is, the first side piece 41). Further, the pressing portion 2 may be supported so as to be rotatable around two axes by a universal joint or the like with respect to the pressing portion mounting portion 74. Further, the pressing portion 2 may be supported so as to be rotatable only about one axis by a hinge or the like with respect to the pressing portion mounting portion 74.

  As described above, when the pressing portion 2 is formed so that the posture with respect to the first side piece 41 is variable, the pressing is performed along the inclined first side surface even if the first side surface of the bathtub is inclined. It becomes possible for the part 2 to contact | abut. As a result, even when the first side surface and the second side surface of the side wall of the bathtub are not parallel, the pressing portion 2 or the pressing receiving portion 3 does not contact only at one point but contacts at two or more points. It is suppressed that the slide 1 becomes easy to come off.

As shown in FIG. 18, the number of bathtubs (BT in the figure) is not only a metal bathtub and a cement bathtub, but also a resin one formed integrally with a bathroom unit in recent years. And most of the side walls (BW in the figure) of the resin bathtub have a cavity between the side wall portion having the first side surface and the side wall portion having the second side surface, and these side wall portions are It is the structure connected with the flange part (BW1 in a figure) of the upper end of a bathtub. For this reason, the distance from the fulcrum (that is, the connected flange part) of both side walls becomes longer as the contact portion between the pressing part 2 and the pressure receiving part 3 goes downward, and the bending moment applied to the fulcrum increases. As a result, the deflection increases. Therefore, the bending moment applied to the fulcrum becomes smaller as the contact portion between the pressing portion 2 and the pressure receiving portion 3 on the side wall of the bathtub goes upward. For this reason, when the handrail 1 for bathtubs is attached to a side wall, either one or both of the pressing part 2 and the press receiving part 3 are contact | abutted with respect to the connection piece 43 located on the upper end surface of a side wall. The location is set as high as possible.

It may be 3 cm or 2 cm. In the resin bathtub, the side wall portion having the first side surface is provided 3-4 cm below the upper end surface of the side wall of the bathtub, and a separate apron (BE in FIG. 18) is attached to the lower side. There are many cases. In such a case, if the contact part to the 1st side surface of the press part 2 is located in the downward direction from the upper end surface of the side wall of a bathtub 4 cm below, it will be applied to an apron and the handrail 1 for bathtubs May not be firmly attached to the side wall of the bathtub. Therefore, it is even more preferable that the lower end of the contact surface 21 of the pressing portion 2 is 4 cm, 3 cm, and 2 cm below the connecting piece 43.

  In the first embodiment, as shown in FIG. 6, the lower end of the contact surface 31 of the press receiving portion 3 is located below the lower end of the contact surface 21 of the press portion 2.

Further, as shown in FIG. 11, the first connecting piece 43a (the bottom of the groove 45) is provided with a plurality of mounting holes 46a penetrating vertically.

  As shown in FIGS. 8 and 9, the first connecting piece 43 a is provided with projecting portions 47 (47 a and 47 b) that project to the left and right outside of the pressing portion 2 and the press receiving portion 3. . The protrusions 47a and 47b prevent the bathtub handrail 1 attached to the side wall of the bathtub from being inclined in the left-right direction. In addition, the projecting portion 47 is provided with a plurality of second ribs 48 having the left-right direction as the longitudinal direction in the front-rear direction.

  As shown in FIG. 12, the receiving side movable portion 1 b includes a connecting portion 4 including a second side piece 42 and a second connecting piece 43 b, and a pressure receiving portion 3 provided in the connecting portion 4. Constitutes a pressure receiving unit. On the front side of the second side piece 42, the pressure receiving portion 3 is supported so that the posture is variable. In this case, as described above, it may be supported so that it can be rotated around an axis in any three-dimensional direction, and can be rotated around two axes by a universal joint or the like. The press receiving portion 3 is provided so as to be rotatable about a vertical axis and a horizontal axis.

  In the first embodiment, as shown in FIG. 13, the connecting shaft 32 is provided so as to be rotatable around the vertical axis, the horizontal axis, and the front-rear axis. The connecting shaft 32 is provided with a flange 33 at the front end of the shaft main body, and a head 34 is provided at the rear end of the shaft main body. Both the flange 33 and the head 34 have a larger diameter than the shaft main body. As shown in FIG. 14, the pressure receiving portion 3 is provided with a shaft support plate 90. The shaft support plate 90 is formed with a shaft insertion hole 93 through which the shaft main body of the connecting shaft 32 can be inserted and the flange 33 cannot be inserted, and a restriction shaft fixing hole 94 to which a rotation restriction shaft 9 described later is fixed. The The shaft support plate 90 is fixed to the rear surface of the press receiving portion 3, and a recess is formed on the front side thereof.

  The flange 33 is inserted into the recess of the pressure receiving portion 3 to prevent the connecting shaft 32 from coming off, and the head 34 is inserted into a connecting shaft insertion hole 42 a formed in the second side piece 42 to connect the connecting shaft 32. It has been secured. The connecting shaft insertion hole 42a may be a through hole or a recess that opens only forward.

  Thereby, if the press receiving part 3 is formed so that the attitude | position with respect to the 2nd side piece 42 becomes variable, even if the 2nd side surface of a bathtub inclines, it presses along the inclined 2nd side surface. It becomes possible for the receiving part 3 to contact | abut. As a result, even when the first side surface and the second side surface of the side wall of the bathtub are not parallel, the pressing portion 2 or the pressing receiving portion 3 does not contact only at one point but contacts at two or more points. It is suppressed that the slide 1 becomes easy to come off.

  Furthermore, a rotation restricting portion that prevents or restricts rotation around the axis in a direction (that is, the front-rear direction) facing the pressing portion 2 of the pressing receiving portion 3 is provided.

  The rotation restricting portion includes a convex portion provided in the press receiving portion 3 and a concave portion provided in the second side piece 42 and into which the convex portion is inserted. In 1st embodiment, it is comprised by the rotation control shaft 9 as a convex part, and the rotation control shaft insertion hole 42b formed in the 2nd side piece 42 as a recessed part. The rotation restricting shaft insertion hole 42b may be a through hole or a recess that opens only to the rear.

  The rotation restriction shaft 9 includes an insertion portion 91 that is inserted into the rotation restriction shaft insertion hole 42 b and a crimping portion 92 that is fixed to the restriction shaft fixing hole 94 of the shaft support plate 90. The caulking portion 92 is fixed to the shaft support plate 90 (that is, the press receiving portion 3) by being fixed around the regulating shaft fixing hole 94 by caulking.

  The insertion portion 91 is thinner than other portions of the rotation restricting shaft 9 and is tapered. In the first embodiment, two rotation restricting shafts 9 are provided on the upper and lower sides. Then, when the insertion portion 91 is inserted into the rotation restricting shaft insertion hole 42b and the press receiving portion 3 tries to rotate about the axis in the front-rear direction, the insertion portion 91 becomes the inner surface of the rotation restriction shaft insertion hole 42b. Rotation is restricted. In other words, the pressure receiving portion 3 is suppressed from tilting in the left-right direction. Thereby, when the handrail 1 for the bathtub is attached to the side wall of the bathtub, the press receiving portion 3 rotates around the axis in the front-rear direction, and it is difficult to attach the handrail 1 for the bathtub to the side wall of the bathtub. It is suppressed.

  As shown in FIG. 12, a handle portion 49 is provided on the rear side of the second side piece 42. The second connecting piece 43b is provided with a mounting hole 46b penetrating vertically. As described above, the first connecting piece 43a is provided with a plurality of mounting holes 46a on the front and rear, and the first connecting piece 43a is fixed in a state where any one of the arbitrarily selected mounting holes 46a and the mounting hole 46b communicate with each other. A tool (not shown) is inserted through the mounting hole 46b and screwed into the mounting hole 46a. By arbitrarily selecting from the plurality of mounting holes 46a, the distance between the first connecting piece 43a and the second connecting piece 43b can be adjusted. In the first embodiment, a plurality of mounting holes 46a are provided, but a single mounting hole 46a may be provided and a plurality of mounting holes 46b may be provided.

  Moreover, in 1st embodiment, as shown in FIG. 11, FIG. 12, the anti-slip | skid member 8 is provided in the contact surface 21 of the press part 2, and the contact surface 31 of the press receiving part 3. As shown in FIG. That is, the anti-slip member 8 forms the direct contact surfaces 21 and 31. The anti-slip member 8 has a coefficient of friction with respect to the first side surface and the second side surface that is higher than that without the anti-slip member 8, and is formed of an elastomer or the like, but the material is not particularly limited. By providing the non-slip member 8, the handrail 1 for the bathtub is more firmly attached to the side wall of the bathtub.
