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. Some handrails for bathtubs can adjust the height of the handrail grip.

  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. In the handrail for bathtubs, the handrail is formed of a pair of support columns and an annular grip attached to be attached between the upper ends of the support columns. Each support column is provided with mounting holes at equal intervals in the upper and lower portions, and through these mounting holes, fixing screws are fixed to the side pieces by screwing fixing screws into the side pieces of the main body. Since the attachment holes are provided at a plurality of positions above and below the support column, the height of the handrail grip is adjusted by selecting the attachment holes through which the fixing screws are passed.

JP 2010-246691 A

  However, in the handrail for bathtubs described in Patent Document 1, when adjusting the grip height of the handrail, it is necessary to pass the fixing screw through the mounting hole and screw the fixing screw into the side piece of the main body tool. Since the handrail is not fixed during the operation of screwing the fixing screw, the user needs to work while supporting the handrail by hand. Thus, in the conventional handrail for bathtubs, in the adjustment of the height of the handrail grip, workability is poor and it is necessary to further improve safety.

  In the handrail for bathtubs thus configured, the handle support portion is coupled to the main body by the coupling portion. That is, in a state where the insertion portion of the connection portion is inserted into at least one of the plurality of holes of the handle support portion, the handle support portion is connected to the main body via the insertion portion of the connection portion. On the other hand, when the insertion portion is not inserted into the hole of the handle support portion, the handle support portion is not connected to the main body.

  The insertion portion is biased by the biasing portion from the outside of the hole of the handle support portion toward the inside of the hole. Therefore, when the user adjusts the height of the handle portion and inserts the insertion portion into the hole of the handle support portion in order to fix the height of the handle portion, a force is applied to the insertion portion while supporting the handle support portion. There is no need to perform operations such as screwing the insertion part. In addition, the user can operate the bias release portion to apply a force to the biasing portion along the direction opposite to the biasing direction of the insertion portion by the biasing portion. It is easy to pull out from the hole.
