  However, in the fixed wall type handrail device, when the user goes in and out of the bathtub, the user turns his body toward the handrail attached to the wall surface and grasps it with his hand to stabilize his posture. Therefore, since it is necessary to cross the side wall of the bathtub while walking sideways to enter and leave the bathtub, the number of movements in the sideways state (that is, the state in which the body is directed along the side wall of the bathtub) increases, resulting in lightness. Or there is a problem in terms of safety.

  Further, in the bathtub fixed type handrail device, the handrail device is fixed on the side wall of the bathtub and the grip portion is relatively small. Although it is relatively easy to grip it because it is near the body of the bathtub user, when the bathtub user approaches or moves away from the bathtub (i.e. It is difficult for the user of the bathtub to hold the posture by holding the grip portion when he / she is relatively distant from the portion, and it is impossible to sufficiently obtain the posture holding function for the bathtub user. There was a problem.

  Therefore, the present invention can assist the bathtub user in maintaining the posture not only when moving in and out of the bathtub but also when moving toward or away from the bathtub, and the movement direction of the bathtub can be faced to the bathtub. The purpose is to provide a handrail device for a bathtub having both high safety and light usability by setting the direction (that is, the direction in which it is easy to walk).

  The present invention employs the following configuration as a specific means for solving the above problem.

  In a first invention of the present application, in a bathtub handrail device including a base placed on a floor near a bathtub and a handrail unit vertically arranged on the base, the handrail unit is the A first strut standing on the base, a second strut standing on a fixture attached to the side wall of the bathtub, and a side wall of the bathtub straddling the upper ends of the first strut and the second strut. It is characterized in that it is provided with a handrail that extends in a direction opposite to.

  A second invention of the present application is characterized in that, in the bathtub handrail device according to the first invention, the handrail units are provided on both end sides in the width direction of the base.

  A third invention of the present application is characterized in that, in the bathtub handrail device according to the first or second invention, the height dimension of each of the columns is configured to be adjustable.

  In a fourth invention of the present application, in the bathtub handrail device according to the first, second or third invention, a plurality of the first support columns are arranged in a row in a direction facing a side wall of the bathtub. Is characterized by.

  In a fifth invention of the present application, in the bathtub handrail device according to the first, second, third, or fourth invention, on one of the base and the bottom of the bath, or both, The feature is that a step is placed.

By moving, for example, compared with the case where the handrail unit is provided only on one side in the width direction of the base, the effect of protecting the bathtub user is improved and the usability is improved. . .

  In addition, a person often unconsciously grasps the handrail with his dominant arm, but if the handrail unit is provided on both the left and right sides of the passage portion on the front side of the bathtub as in the present invention, the bathtub The handrail can always be gripped by the dominant arm both when heading to and coming out of the bathtub. For example, the handrail unit is provided only on one of the left and right sides of the passage part, and the handrail can be gripped by the dominant arm. The protection effect for the bathtub user is improved as compared with the case where it is possible only on either side of going to the bathtub or coming out of the bathtub.

(C) Third invention of the present application In the third invention of the present application, in addition to the effects described in the above (a) or (b), the following unique effects are obtained. That is, according to the present invention, since the height dimension of each of the columns is configured to be increased or decreased, the bathtub user can adjust the height of the handrail according to his or her physical constitution or preference to obtain the handrail. The body can be accurately grasped in a more preferable posture, and the effect of protecting the bath user is improved.

(D) Fourth invention of the present application In the fourth invention of the present application, in addition to the effects described in the above (a), (b) or (c), the following unique effects are obtained. That is, in the present invention, since the plurality of the first support columns are arranged in a row in the direction facing the side wall of the bathtub, the supporting rigidity of the handrail is high, and the reliability of the protective action for the bathtub user is accordingly high. improves.

(E) Fifth invention of the present application In the fifth invention of the present application, in addition to the effects described in the above (a), (b), (c) or (d), the following unique effects are obtained.
