  Therefore, the present invention is a handrail for a bathtub that is installed in a bathtub so that an elderly person or a care recipient who crosses the side wall of the bathtub in a standing position can assist the body movement from the beginning to the end. Thus, an object of the present invention is to provide a handrail for a bathtub that can be securely fixed to the bathtub without clamping the side wall of the bathtub, and that does not interfere with the user's immersion in the bathtub.

  The present inventors have conducted intensive research on the operation when the user stands on the side wall of the bathtub, the mounting position of the handrail for the bathtub in the bathtub, the fixing method, the shape and structure of the handrail for the bathtub, etc. As a result of overlapping, it has been found that the above-mentioned problems can be solved by rotatably attaching a gripping means arranged so as to cross the bathtub to a support base that is detachably fixed to the upper surface of the side wall of the bathtub. The invention has been completed.

  That is, according to the present invention, the left-side base material, the right-side base material, and the rear-side base that connects the left-side base material and the right-side base material placed on the upper surface of the bathtub side wall. A support base material composed of a material, and a rotating member having a front end portion, a left end portion and a right end portion, and rotatably attached to the support base material. In the handrail for a bathtub, the rotating member includes gripping means, and the gripping means is configured such that when the rotating member is closed, the left end of the rotating member is the left side base. The right end of the rotating member is supported by the right side base material so as to cross between the left side base material and the right side base material. There is provided a handrail for a bathtub, which is characterized in that it is arranged in the box.

  Here, terms used in this specification will be described. In this specification, “front” corresponds to the free end side of the rotating member of the handrail for bathtubs, and “rear” corresponds to the support end side of the rotating member of the handrails for bathtub. Therefore, “left” corresponds to one end side in a direction perpendicular to the direction connecting the front and rear of the rotating member, and “right” refers to the other end located on the opposite side of the left. It corresponds to the department side. Since the handrail for bathtubs of the present invention is basically fixed near one corner of the bathtub, the front of the handrail for bathtub corresponds to the inner side of the bathtub, and the rear of the handrail for bathtub corresponds to the outer side of the bathtub. To do. Moreover, the left side of the handrail for bathtubs corresponds to the washing room side of the bathtub or the side wall side of the bathroom, and the left side of the handrails for bathtubs corresponds to the side wall side of the bathroom or the washing room side of the bathtub.

  The material used for the handrail for the bathtub of the present invention is not particularly limited as long as it has the strength required for each part, and is a plastic material, a metal material, a wooden material, a fiber material, or a combination thereof. Composite materials and the like can be used. However, since the inside of the bathroom is a severe corrosive environment of high temperature and humidity, it is preferable to use a plastic material having high corrosion resistance and light weight as a main material for the handrail for the bathtub.

  The supporting base material functions to form a part of the stool portion of the handrail for the bathtub, fix the handrail for the bathtub to the side wall of the bathtub, and rotatably support a rotating member described later. For this reason, if a support base material can be mounted in the upper surface of a bathtub side wall, what has plate shape, rod shape, or the shape which combined them can be used. However, in consideration of stability when the handrail for bathtub is installed on the bathtub side wall, avoiding damage to the upper surface of the bathtub side wall, convenience for the user, etc., the support base material is preferably plate-like, and the bathtub When placed on the upper surface of the side wall, it preferably has a width that can be completely covered so as to hide the upper surface of the bathtub side wall in plan view.

  Moreover, it is preferable that the support base material has a shape that can be arranged along the upper surface shape of the bathtub side wall. Therefore, the support base material is at least a left side base material placed on the left side wall of the bathtub. And a right side base material placed on the right side wall. In this case, when the left side base material and the right side base material are placed on the top surface of the bathtub side wall, they are completely covered so as to hide the top surface of the left side wall and the right side wall of the bathtub in plan view. It is preferable to have a width that can be

  In general, a handrail provided on the side wall of the bathroom is installed so as to protrude from the side wall of the bathroom to the inside of the side wall of the bathtub over the upper surface of the bathtub side wall in order to facilitate attachment / detachment or opening / closing of the bathtub lid. There is almost nothing. For this reason, when the handrail for the bathtub is placed on the upper surface of the bathtub side wall, the support base material, or the left side base material and the right side base material completely cover the upper surface of the bathtub side wall in plan view. If you have a width that can be opened, the pivoting member of the handrail for the bathtub that is placed inside it can open and close freely without interfering with the handrail attached to the bathroom side wall adjacent to the bathtub side wall Will be able to. Further, when the supporting base material, or the left side base material and the right side base material have a width that can cover the upper surface of the bathtub side wall, the rotating member does not come into contact with the upper surface of the bathtub side wall. Therefore, even if it opens and closes repeatedly, the upper surface of the bathtub side wall is not damaged.

  It is preferable that the left side base material and the right side base material are connected to each other by the rear side base material in order to improve rigidity when the bathtub handrail is attached to the bathtub. That is, since the upper surface of one corner of the bathtub side wall usually has a U-shape or U-shape, the left side base material and the right side base material are also rear side in accordance with the top shape of the bathtub side wall. It is preferable that the base material is connected so as to form a substantially U shape or a substantially U shape.

  Further, when the left side base material and the right side base material are connected via the rear support base material, the left side base material, the right side base material and the rear side base material are As long as it can be placed on the upper surface, it is possible to select one having a plate shape, a rod shape, or a combination thereof. For example, a support base material can be configured by connecting a plate-like left side base material and a right side base material made of a plastic material with a rod-like rear side base material made of a metal material. For example, a plate-like left side base material and a right side base material can be integrally formed as a support base material made of the same plastic material by connecting them with a plate-like rear side base material.

  In order to improve the strength of the supporting base material by connecting the left side base material and the right side base material mainly unlike the left side base material and the right side base material. Since it functions, it does not necessarily have a width that can be completely covered so as to hide the upper surface of the rear side wall of the bathtub in plan view.

  A rotating member having a front end, a left end, and a right end is rotatably attached to the rear side base of the support base. Further, the rotating member includes gripping means, and when the rotating member is closed, the left end portion of the rotating member is supported by the left side base material, and the gripping means has a right side of the rotating member. Since the side end is supported by the right side base material, between the left side base material fixed to the left side wall of the bathtub and the right side base material fixed to the right side wall, that is, the bathtub It arrange | positions so that it may cross between the left side wall and the right side wall.

  As described above, in the present invention, the support base, the rotating member, or the gripping means attached to the rotating member is located on the opposite side from the outside of the bathtub (washing place) to the inside of the bathtub and the outside of the bathtub (washing place). It arrange | positions to the bathtub side wall located. For this reason, the user of the handrail for the bathtub of the present invention faces the handrail for the bathtub when straddling the side wall of the bathtub in the standing position, from the outside of the bathtub (washing area) to the inside of the bathtub and the outside of the bathtub. Since it is possible to continuously grasp the grip means of the handrail for the bathtub or place the hand on the rotating member or the support base until it reaches the bathtub side wall located on the opposite side to the (washing place) Thus, the user can easily enter and exit the bathtub while supporting his / her body with the handrail for the bathtub.

  In particular, the handrail for bathtubs of the present invention is different from the conventional handrails for bathtubs as described in Patent Documents 1 and 2, and the opposite side from the outside of the bathtub (washing area) so as to cross the bathtub. Therefore, the user can freely access the handrail for the bathtub without selecting the position and direction for accessing the handrail for the bathtub. For this reason, the user can grasp the handrail for the bathtub of the present invention or attach the hand using both hands and arms widened to the width of the shoulder of his or her shoulders or more easily in the standing position. It becomes possible to straddle the side wall of the. Moreover, since the handrail for bathtubs of this invention can flip up the rotation member arrange | positioned at the opening part of a bathtub, it does not become a hindrance to the user during bathing.

  The handrail for a bathtub of the present invention is a left-side stopper that is slidable in the lateral direction of the left-side base material on the lower surface of the left-side base material, and that can be brought into contact with the inner surface of the bathtub side wall. It is preferable that the lower surface of the right side base material is provided with a right side stopper that is slidable in the lateral width direction of the right side base material and that can be brought into contact with the inner surface of the bathtub side wall.

  The structure of the stopper is not particularly limited as long as it can be slidably moved in the width direction on the lower surface of the left side base material or the lower surface of the right side base material and can be fixed at a predetermined position. is not. For example, the stoppers described in Patent Documents 3 to 5 can be diverted as stoppers for handrails for bathtubs of the present invention. As a result, the handrail for bathtubs of the present invention causes the left hand stopper and the right hand stopper to abut against the inner surface of the bathtub side wall, so that the supporting base material of the handrail for bathtubs is brought to the side wall of the bathtub by the frictional force of both stoppers Since it can attach easily and firmly, it can attach reliably to a bathtub and a bathtub side wall detachably, without clamping the side wall of a bathtub.

  In the handrail for bathtubs of this invention, it is preferable that the rotation member is made from the plate-shaped member. When the rotating member is made of a plate-like member, the user sits on the rotating member of the bathtub handrail by attaching the handrail for bathtub of the present invention to a part of the opening of the bathtub. It is convenient that the user can move from the outside to the inside of the bathtub or from the inside to the outside as it is.

  For this reason, when the rotating member is closed, for example, if it is supported by a shelf board or the like protruding from the inside of the left side base material and the inside of the right side base material, it is arranged inside the support base material. It can also be attached to the support substrate. In this case, since the rotating member, the left side base material, and the right side base material can form a continuous upper surface, the accessibility to the handrail for the bathtub is further improved, and the user can It becomes possible to easily access the handrail for bathtubs without selecting the position and direction to be touched by the hand in the handrail.

  Further, when the rotating member is mounted so as to be disposed inside the support base material, when the rotary member is closed, no substantial gap is generated between the rotating member and the support base material. That is, it is possible to improve the safety when the user accesses the handrail for the bathtub by preventing the gap between the user's fingers and the like from being formed.

  Furthermore, in the handrail for bathtubs of the present invention, the upper surface of the rotating member may be formed so as to be substantially flush with the upper surface of the support base material when the rotating member is closed.

  When the rotating member is closed, the upper surface of the supporting base and the upper surface of the rotating member are substantially flush with each other, the accessibility to the bathtub handrail is further improved, and the user can Since it becomes possible to move on the upper surface of the handrail for the bathtub so as to slide the palm and the buttocks, it is safer and easier to enter and exit the bathtub.

  Also, the central portion of the front end of the rotating member, the front edge of the left side base material, and the front edge of the right side base material are arranged so as to be aligned on a substantially straight line when the rotating member is closed. It is preferable that When the front end other than the left and right recesses of the rotating member and the front edge of the left side base material and the right side base material are arranged so as to be aligned on a substantially straight line, a rectangular general-purpose lid for a bathtub So that the handrail for bathtub of the present invention can be used as a part of the lid of the bathtub.

  Moreover, in the handrail for bathtubs of this invention, it is behind the front edge part of the center part of the front end part of a rotation member, and the left side base material in the left end part side of the front end part of a rotation member. A concave portion that is curved to the right is formed, and on the right end side of the front end portion of the rotating member, the center portion of the front end portion of the rotating member and the front edge portion of the right side base material are bent rearward. A recess may be formed.

  Since the front end portion of the rotating member has a concave portion that is curved rearward from the center portion at the left and right end portions thereof, the user does not necessarily have to take an unnatural posture and visually feel the palm. For example, the positions (recesses) of the left and right ends of the rotating member can be confirmed. Also, if the concave portion is cut out to fit the user's palm, when the user opens and closes the rotating member, the palm is naturally guided to the concave portion of the rotating member. The rotating member can be safely opened and closed without a hand being sandwiched between the member and the bathtub side wall or between the rotating member and the support base.

  For this reason, the left shelf and the right shelf for supporting from the lower side when the rotating member is closed face the inside of the left side substrate and the right side substrate of the handrail for the bathtub. It is preferable that the protrusion is provided. Further, the front edge of the left shelf is arranged so as to be flush with or located behind the front end of the recess of the rotating member when the rotating member is closed, and to the right The front edge portion of the side base material is disposed so as to be flush with or located behind the front end portion of the concave portion of the rotating member when the rotating member is closed.

  In particular, when the rotating member is closed, the front edge of the left shelf and the front edge of the right shelf are arranged so as to be located behind the recess of the rotating member. Even if the user's hand that grips the moving member is turned to the back surface of the rotating member in the recess, the user's hand is between the rotating member and the left shelf, It can prevent effectively that it is pinched | interposed between right side shelf parts.

  In addition to the front end portion, the rotating member preferably further includes a substantially straight left end portion and a right end portion facing each other in a direction substantially perpendicular to the front end portion. When the supporting member of the handrail for the bathtub, or the left side base material and the right side base material have a width that can cover the upper surface of the bathtub side wall, the rotating member is plate-shaped. Since the left end and right end of the moving member are formed along the inner edge of the support base, the left end and right end of the rotating member are supported when the rotating member is closed. It is attached so as to be arranged inside the substrate. For this reason, the left end and the right end of the rotating member can freely open and close the rotating member without interfering with the handrail attached to the bathroom side wall adjacent to the bathtub side wall. Become.

  In addition, when the bathtub handrail is attached to the upper surface of the bathtub side wall, the pivoting member of the bathtub handrail does not overlap with the upper surface of the left side wall and / or the upper side surface of the right side wall in plan view. It can also be arranged. Generally, the handrail provided on the side wall of the bathroom is hardly installed so as to protrude from the side wall of the bathroom to the inside of the bathtub side wall beyond the upper surface of the bathtub side wall in order to easily open and close the lid. For this reason, when the handrail for the bathtub is attached to the upper surface of the bathtub side wall, the rotating member is disposed at a position that does not overlap the upper surface of the left side wall and / or the right side wall of the bathtub side wall in plan view. The moving member can be freely opened and closed without interfering with the handrail attached to the bathroom side wall adjacent to the bathtub side wall. In addition, since the rotating member does not come into contact with the upper surface of the bathtub side wall, the upper surface of the bathtub side wall is not damaged even if it is repeatedly opened and closed.

  Well-known techniques such as hinges and ball joints can be adopted as the turning means of the turning member, and there is no particular limitation. Further, the rotating member may be attached to the rear side base material in the supporting base material, or the left side base material is sandwiched between the left side base material and the right side base material from both sides thereof. And may be rotatably supported on the right side base material.

  The bathtub handrail of the present invention preferably includes a knob having a substantially flat support surface for supporting the palm of the user on the upper surface of the rotating member as a gripping means.

  The handrail for a bathtub is used when a physically handicapped person such as an elderly person or a care recipient straddles a side wall of the bathtub in a standing state. In this case, the user faces the handrail for the bathtub and puts his hand on the upper surface of the handrail for the bathtub so as to straddle the side wall of the bathtub. For this reason, if a knob is provided on the upper surface of the handrail for the bathtub, the user can securely deposit a part of his / her weight to the handrail for the bathtub by attaching a hand to the knob. It becomes possible to straddle the side wall of the bathtub in a safe and easy standing state. In addition, the handrail for bathtubs of the present invention is hung over a part of the opening of the bathtub when the rotating member is plate-shaped, so that persons with physical disabilities such as elderly people and care recipients It can also be used to move from the outside of the bathtub to the inside or from the inside to the outside while sitting on the handrail for the bathtub.

  For this reason, it is preferable that a substantially flat support surface is formed on the upper surface of the knob. Since elderly people and those who need care often do not have sufficient grip strength, if a substantially flat support surface is provided on the top surface of the knob, the user can put the palm, back of the hand or fist on the support surface of the knob. You can leave a part of your weight on the handrail for the bathtub without sliding your hand by just putting it down or holding the knob lightly. As a result, the user can cross over the side wall of the bathtub in a safer and more easily standing position. For this reason, the knob is preferably substantially circular in plan view. By making the shape of the top surface of the knob or the entire shape of the knob into a substantially circular shape in plan view, the user can easily access the knob from any direction. A part can be deposited in the handrail for bathtubs.

  Moreover, in order to make it easy to support a user's palm, back of a hand, or a clenched fist stably, the support surface of the knob may be formed with a recess recessed from the side to the center. Moreover, when it is disliked that a water | moisture content accumulates on the support surface of a knob, the convex part which swelled toward the center from the side surface may be formed.

  When the support surface of the knob is recessed from the side surface toward the center, it is preferable to provide a drain hole or a drain groove for preventing moisture from accumulating on the support surface of the knob. In particular, when a drainage groove is provided on the support surface of the knob, it is preferable to provide at least one groove portion having a bottom surface bulging from the side surface toward the center. In this case, the water accumulated on the support surface of the knob is guided to the groove, and the water accumulated on the support surface is drained from the vicinity of the center of the knob to the side opening through the groove. The groove also functions to prevent the user from slipping on the support surface when the user places the palm, back of the hand, or fist on the support surface of the knob. For this reason, a plurality of grooves may be provided on the support surface of the knob in a lattice shape or a radial shape.

  The knob is composed of a grip part that is accessed by the user's hand, and a support part for attaching the grip part to the upper surface of the rotating member, and the maximum cross-sectional area of the horizontal section of the grip part is the support part. It is preferable that it is larger than the maximum cross-sectional area of the horizontal cross section. In this case, the support surface formed on the upper surface of the knob matches the upper surface of the grip portion.

  If the knob consists of a grip part and a support part, and the maximum cross-sectional area of the horizontal cross section of the grip is larger than the maximum cross-sectional area of the horizontal cross-section of the support part, even the user who has insufficient grip strength will Since a finger can be easily hooked, a part of his / her weight can be deposited in the grip portion in a more stable state.

  Moreover, in the handrail for bathtubs of this invention, it is preferable that the grip part is attached to the upper surface of the handrail for bathtubs via one support | pillar part. When the grip part is supported by a single support part, the user can easily grasp the grip part from any direction or place a fist on the grip part without choosing a position to access the grip part. A part of the body weight can be deposited in the grip portion, and the strength of the entire knob is improved, so that safe use by the user is guaranteed.

  Further, it is preferable that the outer peripheral portion of the grip portion is provided with a side surface having substantially the same width for a user to hang a finger, and the side surface of the grip portion is connected to the support surface by a continuous curved surface. If the outer periphery of the grip part is formed with side surfaces of approximately the same width, the user can easily grip the grip part from any direction, and the side surface of the grip part is supported by a continuous curved surface. When connected to the surface, the fit of the grip portion to the palm of the user is also improved. For this reason, as long as the side surface of a grip part has the substantially same width | variety, it may have a substantially flat shape in side view, and may have a shape which bulged a little outside.

  The knob is attached at a position near the front end of the turning member of the handrail for bathtubs and at a position near the left end and / or a right end of the turning member. Is preferred. For example, if the user uses the handrail for bathtubs to move mainly in the sitting position, the knob is attached to the position near the front end of the rotating member and opposite to the washing area side. For example, if the user uses the handrail for the bathtub in a standing position with the hand mainly placed, the knob is positioned near the front end of the rotating member and is on the washing room side It is preferably attached at a position on the opposite side or near the front end, and at a position on the washing room side and a position on the opposite side.

  When the user crosses the bathtub side wall in a standing position using the handrail for the bathtub, the user faces the bathtub handrail and places the hand on the knob of the bathtub handrail to straddle the bathtub side wall. become. For this reason, the knob is attached at a position near the front end of the turning member of the handrail for bathtubs and at a position near the left end and / or near the right end of the turning member. The user can easily access the knob and can support his body. In addition, when the user tries to enter and exit the bathtub while sitting on the handrail for the bathtub, the user can easily move his / her body using the knob.

  In addition, when the knob is positioned near the front end of the rotating member, the user who sits on the handrail for the bathtub slightly lifts his knee even when the knob is attached to the washing area. Since the user can get over the knob together with the side wall of the bathtub just by lifting it, the knob does not become an obstacle when the user tries to enter or leave the bathtub in the sitting position. Further, since the knob is attached to the rotating member, not the support base material, the opening and closing of the rotating member is facilitated by using the knob. Further, since the front end of the rotating member is separated from the rotating shaft, the user can open and close the rotating member with a smaller force than when the knob is mounted near the rotating shaft. become.

  In the handrail for bathtubs of this invention, it is preferable to be able to change / move the attachment position of the knob on the handrail for bathtubs according to a user's physique. For this reason, the knob is provided with first engaging means such as a male screw, and a plurality of second engaging means such as female screws (screw holes) are provided on the upper surface of the rotating member. By installing and selecting the second engaging means to be engaged with the first engaging means, the knob mounting position can be changed / moved.

To function. For this reason, if the support base material 3 can be mounted in the upper surface 21 of the bathtub side wall 20, what has plate shape, rod shape, or the shape which combined them can be used. However, in this embodiment, in consideration of the stability when the handrail 1 for a bathtub is installed on the bathtub side wall 20, the avoidance of damage to the upper surface 21 of the bathtub side wall 20, the convenience of the user, etc., the plate-like support A substrate 3 is used.

  The support base material 3 is a plate-like left side base material 31 a placed on the upper surface of the left side wall 22 a of the bathtub 2 and a plate-like right side placed on the upper surface of the right side wall 22 b of the bathtub 2. It includes a side base material 31b and a plate-like rear side base material 31c placed on the upper surface of the rear side wall 22c of the bathtub 2, and is integrally formed so as to form a substantially U-shape in plan view as a whole. Has been. For this reason, since the support base material 3 which concerns on this embodiment can be arrange | positioned so that the shape of the upper surface 21 of the bathtub side wall 20 may be arrange | positioned, stability at the time of attaching to the bathtub 2 is high, and it has very high rigidity.

  When the left-side base material 31a, the right-side base material 31b, and the rear-side base material 31c according to the present embodiment are placed on the upper surface 21 of the bathtub side wall 20, the left side wall 22a of the bathtub 2 respectively in a plan view. , The right side wall 22b, and the rear side wall 22c have a width that can be completely covered so as to hide. On the other hand, in recent years, as shown in FIGS. 1 and 2, a handrail 6 is often provided on the side wall of the bathroom adjacent to the bathtub 2, but the lid of the bathtub 2 is attached / removed or opened / closed. In order to make it easy, the handrail 6 is hardly installed so as to protrude from the side wall of the bathroom to the inside of the bathtub side wall 20 beyond the upper surface 21 of the bathtub side wall 20. For this reason, in the handrail 1 for bathtubs concerning this embodiment, the rotation member 4 arrange | positioned inside the support base material 3 opens and closes freely, without interfering with the handrail 6 attached to the side wall of the bathroom. can do. Further, since the rotating member 4 does not directly contact the upper surface 21 of the bathtub side wall 20, the upper surface 21 of the bathtub side wall 20 is not damaged even if the rotating member 4 is repeatedly opened and closed.

  The rotating member 4 according to the present embodiment is a plate-like member having a substantially quadrangular shape, and at each end, a front end having recesses 41a and 41b whose left and right end portions are curved backward rather than the center portion. Part 40, a substantially straight rear end 42c facing the front end 40, a substantially straight left end 42a adjacent to the front end 40 and the rear end 42c at a substantially right angle and facing each other. A substantially straight right end 42b is formed (FIG. 2). Furthermore, the recessed parts 41a and 41b formed in the front end part 40 of the rotating member 4 are the front edge part of the left side base material 31a and the front edge part of the right side base material 31b which are arrange | positioned on each outer side. It is bent backward (Fig. 2). Since the handrail 1 for bathtubs which concerns on this embodiment can flip up the rotation member 4 arrange | positioned at the opening part of the bathtub 2, it does not become an obstacle of the user during bathing.

  The front end 40 is a free end of the rotating member 4, and the other rear end 42 c, left end 42 a and right end 42 b are each provided on the support base 3 when the rotating member 4 is closed. The rear side base material 31c, the left side base material 31a, and the right side base material 31b are arranged inside them so as to be in contact with each other (FIG. 1). For this reason, when the handrail 1 for bathtubs is attached to the upper surface 21 of the bathtub side wall 20, the rotation member 4 does not overlap with the upper surface of the left side wall 22a of the bathtub side wall 20 and the upper surface of the right side wall 22b in plan view. Placed in position.

  The rotating member 4 includes a knob 5 as a gripping means. When the rotating member 4 is closed, the left end portion 42a of the rotating member 4 is supported by the left side base material 31a. The right end portion 42b of the rotating member 4 is supported by the right side base material 31b, so that the left side base material 31a fixed to the left side wall 22a of the bathtub 2 and the right side wall 22b are fixed. It is arranged so as to cross between the right side base material 31b, that is, between the left side wall 22a and the right side wall 22b of the bathtub 2.

  Thus, in the handrail 1 for bathtubs according to the present embodiment, the support base 3, the rotating member 4, or the knob 5 attached to the rotating member 4 is provided on the bathtub 2 from the outside (washing area) of the bathtub 2. It can arrange | position in arbitrary positions to the bathtub side wall 20 located in the other side of the inside and the exterior (washing area) of the bathtub 2. For this reason, the user of the bathtub handrail 1 according to the present embodiment faces the bathtub handrail 1 when straddling the side wall 20 of the bathtub 2 in a standing position, from the outside of the bathtub 2 (washing area), The knob 5 of the handrail 1 for the bathtub is continuously gripped, or the rotating member 4 and the support are provided until the inside of the bathtub 2 and the bathtub side wall 20 located on the opposite side to the outside of the bathtub 2 (washing area). Since the hand can be placed on the base material 3, the user can easily enter and exit the bathtub 2 while supporting his / her body with the handrail 1 for the bathtub.

  In particular, the handrail 1 for bathtubs according to the present embodiment is different from conventional handrails for bathtubs as described in Patent Documents 1 and 2, and the outside of the bathtub 2 (washing area) so as to cross the bathtub 2. ) To the bathtub side wall 20 located on the opposite side, the user can freely access the bathtub handrail 1 without selecting the position and direction to access the bathtub handrail 1. it can. For this reason, the user can hold the handrail 1 for a bathtub according to the present embodiment or attach a hand using both hands and arms widened to the width of his or her shoulders, and in a standing position. It becomes possible to straddle the side wall 20 of the bathtub 2 easily.

If it is arranged at a position that does not overlap with the upper surface of the left side wall 22a and the upper surface of the right side wall 22b of the bathtub side wall 20, when it is closed, the left end 42a 'and the right end 42b' You may arrange | position inside those base material 31a 'and right side base material 31b' of support base material 3 'so that it may touch. In the case of this embodiment, the rear side base material 31c ′ that connects the left side base material 31a ′ and the right side base material 31b ′ is formed on the rotating member 4 ′ when the rotating member 4 ′ is closed. It is arranged so as to be hidden underneath.

  By the way, as described above, the handrail 6 provided on the side wall of the bathroom adjacent to the bathtub 2 is almost installed so as to protrude from the side wall of the bathroom to the inside of the bathtub side wall 20 beyond the upper surface 21 of the bathtub side wall 20. Therefore, the rotating member 4 arranged at a position that does not overlap the upper surface of the left side wall 22a and the upper surface of the right side wall 22b of the bathtub side wall 20 is attached to the side wall of the bathroom. It can be freely opened and closed without interfering with the handrail 6. Further, since the rotating member 4 does not directly contact the upper surface 21 of the bathtub side wall 20, the upper surface 21 of the bathtub side wall 20 is not damaged even if the rotating member 4 is repeatedly opened and closed.

  Further, the front end portion 40 of the rotating member 4 is formed with concave portions 41a and 41b whose left and right end portions are curved rearward from the central portion. More specifically, on the left end portion 42a side of the front end portion 40 of the rotation member 4 rotatably attached to the support base 3, a central portion of the front end portion 40 of the rotation member 4 and The left side base material 31a is recessed (curved) rearward from the front edge portion, and a left concave portion 41a for gripping with the palm of the user's palm is formed, and the front end portion 40 of the rotating member 4 is formed. On the right end portion 42b side, the center portion of the front end portion 40 of the rotating member 4 and the front edge portion of the right side base material 31b are recessed (curved) in order to be grasped by the user's palm. Are formed on the right side recess 41b.

  For this reason, in the handrail 1 for bathtubs which concerns on this embodiment, the user does not necessarily need to take an unnatural posture and it does not necessarily look visually, but was provided in the front end part 40 of the rotation member 4 by the touch etc. of the palm. The positions of the left recess 41a and the right recess 41b can be confirmed. Further, since the left concave portion 41a and the right concave portion 41b are cut out so as to fit the palm of the user, the user can naturally rotate the palm of the user when opening and closing the rotating member 4. It is guided to the left recessed portion 41a or the right recessed portion 41b of the member 4 and is safe without being caught between the rotating member 4 and the bathtub side wall 20 or between the rotating member 4 and the support base 3. The rotating member 4 can be opened and closed.

  Moreover, as FIG. 1 shows, the rotation member 4 is made into the inner side of the left side base material 31a of the handrail 1 for bathtubs, ie, the rotation member 4 side of the left side base material 31a from the downward direction. A left shelf 30a is provided to support the front edge 301a of the left shelf 30a from the end of the left recess 41a of the rotation member 4 when the rotation member 4 is closed.
