Description

  The present invention generally relates to a handrail for a bathtub, and more particularly to a handrail for a bathtub that is detachably attached to the bathtub.

  Conventionally, there is a handrail for a bathtub that is detachably attached to the side wall of the bathtub. For example, JP 2010-246691 A (Patent Document 1) describes a handrail for a bathtub that is used by being attached to the upper end portion of the side wall of the bathtub. When using this handrail for bathtubs, first, place the main body tool over the upper end of the side wall so that the side piece is located outside the bathtub, and the pressing plate of the pressing tool on the outer surface of the bathtub on the side wall, The pressure receiving plate of the pressure receiving member is opposed to the surface of the side wall in the bathtub. Then, by sliding the slide pieces of the pair of press receivers to the back of the insertion holes of the main body tool, the press receiver plates of each press receiver are moved, and the slip stoppers of the press receiver plates are prevented from slipping on the surface of the side wall bathtub. The outer surface on which the sheet is pasted is brought into contact.

  In the handrail for bathtubs of Patent Document 1, an engagement groove is provided in the slide piece of the press receiver, and a latch claw is provided in the main body. The latch claw is biased toward the slide piece and is engaged with the engagement groove. A slide inclined surface is formed on the latch claw, and an inclined surface is formed on the engagement groove. The slide inclined surface of the latch claw and the inclined surface of the engaging groove face each other in the direction in which the slide piece is slid to the back of the insertion hole. By applying a force for pushing the slide piece into the insertion hole, the slide inclined surface of the latch claw is pushed by the inclined surface of the engagement groove, and the latch claw comes out of the engagement groove. For this reason, a pressure receptacle can be slid without big resistance by applying force in the direction which pushes a slide piece into the back of an insertion hole.

  Japanese Patent Laying-Open No. 2013-52207 (Patent Document 2) describes a handrail for a bathtub provided with a width adjusting means. In this bathtub handrail, an L-shaped slide body is inserted into an L-shaped main body, and is fitted and slid. A lid having a lock pin on the back surface is provided on the upper portion of the main body. The lock pin is engaged and locked with the engagement hole of the slide body simply by pushing the slide body, and the lock pin is detached from the engagement hole and unlocked by opening the lid.

  The lock pin is biased by a spring, and an inclination is formed at the tip of the lock pin. When the slide body is inserted into the fitting portion of the main body and pushed in, the tip of the slide piece comes into contact with the inclined surface of the lock pin, the lock pin is pushed upward against the spring bias, and the slide body moves forward.

  International Publication No. WO 2013/114610 (Patent Document 3) describes a handrail for a bathtub in which a fixed frame and a movable frame are engaged with band teeth. The band tooth has an inclined surface that allows the movable frame to advance, and when the movable frame is slid so as to approach the bathtub wall surface, the inclined surface of the band tooth of the movable frame slides on the inclined surface of the band tooth of the fixed frame. Therefore, when the user slides the movable frame closer to the bathtub wall surface, the user only needs to move the movable frame by grasping the grip, and there is no need for another operation such as releasing the stop of the slide.

You may be comprised so that it may move along a direction.

  The usage method of the handrail 1 for bathtubs comprised as mentioned above is demonstrated.

  When the bathtub handrail 1 is attached to the side wall of the bathtub, first, the fixed frame 110 and the movable frame 120 are combined, and the distance between the pressing plate 104 and the pressure receiving plate 105 is wider than the thickness of the side wall of the bathtub. Thus, the main body 100 is disposed on the side wall of the bathtub. The main body 100 is arranged such that the lower surface of the horizontal portion 111 of the fixed frame 110 is in contact with the upper surface of the side wall of the bathtub, and the pressing plate 104 faces the outer side wall surface of the bathtub (the outer surface of the side wall of the bathtub). The main body 100 is disposed such that the pressure receiving plate 105 faces the inner side wall surface of the bathtub (the inner side surface of the bathtub side wall).

  Next, the user holds the side grip 160 of the main body 100 and holds the side grip 160 while pulling upward the operation portion 143 exposed on the upper surface of the cover 101 of the main body 100, thereby moving the movable frame 120. The horizontal portion 121 is slid on the horizontal portion 111 of the fixed frame 110 along a direction orthogonal to the side wall surface of the bathtub. When the operation unit 143 is pulled upward, the cylinder 141 moves in the chamber 170 in a direction away from the circular hole 130. In this way, the engagement between the circular hole 130 and the cylinder 141 is released, and the movable frame 120 is easily slid. In this way, the positions of the fixed frame 110 and the movable frame 120 are adjusted so that the pressing plate 104 comes into contact with the outer side surface of the bathtub side wall and the press receiving plate 105 comes into contact with the inner side surface of the bathtub side wall.

  A plurality of circular holes are formed in the circular hole 130. The width between the fixed frame 110 and the movable frame 120 can be adjusted by changing which circular hole 130 is fitted to the column 141.

  If necessary, the user can turn the handle knob 107 to finely adjust the pressing plate 104 and the pressing receiving plate 105 so that they completely come into contact with the side wall of the bathtub. By doing in this way, the handrail 1 for bathtubs can be firmly fixed on the side wall of a bathtub.

  In a state where the operation unit 143 is not pulled up by the user, the protrusion of the column 141 and the circular hole 130 are engaged as described above. At this time, the vertical surface 130a of the circular hole 130 and the vertical surface 141a of the cylinder 141 are opposed to each other. Therefore, even if the user applies a force to the movable frame 120 so as to move the pressure receiving plate 105 away from the side wall of the bathtub or close to the side wall of the bathtub, the vertical surface 130a and the vertical surface 141a are pressed against each other. Therefore, the movable frame 120 is not slid.

  When removing the handrail 1 for the bathtub from the bathtub, the user first holds the movable part 120 while holding the side grip 160 while pulling upward the operation part 143 exposed on the upper surface of the cover 101 of the main body 100.

Since the column 141 is connected to the operation unit 143 disposed on the surface 123 side of the movable frame 120 by the connection unit 144, the user operates the operation unit 143 from the surface 123 side of the movable frame 120 to slide the cylinder 141. The cylinder 141 of the stop / release means 140 can be separated from the circular hole 130 formed in the surface 123 of the movable frame 120. In this way, the circular hole 130 or the cylinder 141 can be operated without the user touching it directly.

  Further, the vertical surfaces 130a and 141a that are contact surfaces between the circular hole 130 and the cylinder 141 are surfaces orthogonal to the surface of the movable frame 120 and include surfaces that are not parallel to the sliding direction of the movable frame 120. Unless the user operates the operating portion 143 to pull up the slide locking / releasing means 140 against the biasing force of the spring 145 and separate the surface-side column 141 of the movable frame 120 from the circular hole 130, the circular hole 130 and the cylinder 141 come into contact with each other in a plane that is not parallel to the sliding direction of the movable frame 120, thereby preventing the movable frame 120 from sliding. In this way, it is possible to prevent the movable frame 120 from being accidentally slid.

  The user pulls up the slide locking / releasing means 140 against the urging force of the spring 145 by operating the operation unit 143 when moving the movable frame 120 close to the wall surface of the bathtub or away from the wall surface of the bathtub. Thus, the movable frame 120 can be slid. In this way, the movable frame 120 can be slid in any direction by the same operation, and thus the operation is easy.
