Description

  INDUSTRIAL APPLICABILITY The present invention is supplementarily used to firmly attach a bathtub fixture attached by clamping the bathtub side wall from the washing place side and the bathtub side to the bathtub side wall having an outer wall that does not have strength in part. In particular, the pressing force of the clamp part of the bathtub fixing tool is applied to the strength of the bathtub side wall with respect to the bathtub side wall having an outer wall provided with a strong rim portion and an apron portion having no strength. The bathtub fixing device can be firmly attached to the bathtub side wall by being configured to be able to cancel the rotational moment generated by the displacement of the position of the pressing point on the washing place side and the bathtub side. It is related with the auxiliary tool for bathtubs.

  Conventionally, as a general-purpose fixing device for a bathtub that is attached using a side wall of a bathtub so that an elderly person or the like can easily support the body when entering or leaving the bathtub, for example, JP-A-9-252985 (Patent Document 1), US Pat. No. 3,968,524 (Patent Document 2), US Pat. No. 4,888,323 (Patent Document 3), WO2013 / 114610 International Publication (Patent Document 4), and the like, 2. Description of the Related Art Bathtub fixtures such as a bathing transfer table described in JP-A-8-266436 (Patent Document 5) and JP-A-9-108138 (Patent Document 6) are known. In order to attach to the bathtub side wall, the structural features common to these general-purpose bathtub fixtures are that one side of the bathtub presses the side wall of the bathtub from the surface of the washing area and the other side presses the surface from the bathtub side. The clamp portion is provided.

  On the other hand, in recent years, the systematization of bathtubs and bathrooms has been promoted for the purpose of improving workability of bathtubs and bathrooms, improving functionality such as the thermal insulation effect of bathtubs, and improving design. Among these, in order to improve the heat retention, design, and maintainability of the bathtub, for example, plastic resin such as FRP, artificial marble, and stainless steel as described in JP-A-2006-141756 (Patent Document 7). The mainstream is composed of a bathtub body made of materials, a heat insulating material made of foamed resin covering the outer periphery of the bathtub body, and a bathtub apron (decorative board) covering the bathtub body and the heat insulating material from the outside. It's getting on. Also, in order to improve the handling and maintainability of the connecting part between the bathtub body and the bathtub apron, a rim part is generally formed at the upper part of the bathtub body side wall, and the floor part is integrated with the floor at the lower part of the bathtub body side wall. A waterproof pan is formed, and a bathtub apron is detachably installed via the rim portion and the waterproof pan.

  However, since the bathtub apron is detachably installed for the purpose of making up the bathtub body, the bathtub apron is weak in strength and has a structure that cannot particularly withstand external force such as pressing. Moreover, the connection part of the bathtub apron and the rim | limb part of a bathtub main body is generally provided with the level | step difference by the restrictions on the structure, etc. in many cases. For this reason, in the case of the type of fixture for bathtubs that is attached to the side wall of the bathtub by pressing and clamping the side wall of the bathtub with the surface from the washing room side and the bathtub side as described above, the clamping part on the washing room side is fragile. There is a problem that the fixing device for the bathtub cannot be firmly attached to the side wall of the bathtub because the apron is pressed and damaged, or the clamp surface runs on the step between the bathtub apron and the bathtub rim. there were.

  In addition, according to the instruction manual for the above-mentioned bathtub fixing tool, when the rim part protrudes from the bathtub apron, the bathtub fixing tool can be attached to the bathtub apron by placing a spacer on the surface of the bathtub apron. It is recommended to clamp the bathtub side wall after eliminating the step with the rim. However, when a spacer is used as described above, the problem that the clamp part of the bathtub fixing device runs on the rim part is reduced, but the clamp part changes to pressing the fragile bathtub apron through the spacer. Therefore, there is still a problem that the bathtub fixture cannot be damaged or the bathtub apron cannot be firmly attached to the bathtub side wall.

  On the other hand, in order to solve the above problem, for example, as described in Design Registration No. 1518663 (Patent Document 8), it is formed narrow in the height direction so as to press only the bathtub apron from the washing area side. The clamp part and the clamp part formed wide in the height direction so as to press the side wall from the bathtub side so that it can be firmly attached to the bathtub side wall having the bathtub apron (decorative plate) An improved handrail for bathtubs for unit baths has been developed.

  However, the handrail for a bathtub dedicated to a unit bath described in Patent Document 8 is expensive as it is a dedicated product and has a complicated structure as compared with the general-purpose bathtub fixture described above. There is a problem that it cannot be firmly attached to a conventional bathtub side wall that does not include a section.

JP-A-9-252985 US Pat. No. 3,968,524 US Pat. No. 4,887,323 WO2013 / 114610 International Publication JP-A-8-266436 JP-A-9-108138 JP 2006-141756 A Design registration No. 1518663

  Therefore, the present invention is a general-purpose bathtub fixing that is attached to the bathtub side wall by clamping the bathtub side wall from the washing place side and the bathtub side with respect to the bathtub side wall of the unit bath provided with a part of the outer wall having no strength. Also in a tool, it aims at providing the auxiliary tool for bathtubs which makes it attach firmly to a bathtub side wall.

  The present inventors have a structural feature and strength of a general-purpose bathtub fixing device including one clamp portion that is pressed by a surface from the washing area side and the other clamp portion that is pressed by a surface from the bathtub side. As a result of earnest research on the structural features of the unit bath having an outer wall with a part and an apron part having no strength, the result is that the bathtub side wall of the unit bath with a part of the outer wall having no strength For the bathtub configured to guide the pressing force of the clamp part of the bathtub fixture to the strength part of the bathtub side wall and to cancel the rotational moment caused by the displacement of the pressing point on the washing place side and the bathtub side It has been found that by using an auxiliary tool, a clamp-type general-purpose bathtub fixture can be firmly attached to the bathtub side wall of the unit bath, and the present invention has been completed.

  That is, according to this invention, in order to clamp the side wall of a bathtub from the washing-room side and the bathtub side, the fixing tool for bathtubs provided with the 1st press part and the 2nd press part to the said bathtub side wall Auxiliary equipment for a bathtub that is used auxiliary when fixing, a pressure receiving part that makes contact with the first pressing part of the fixing tool for bathtub, and an auxiliary pressing part that makes contact with the rim part of the bathtub side wall And the auxiliary tool for bathtubs which consists of a leg part which supports the said pressure receiving part and the said auxiliary | assistant press part, and is installed in the floor surface of a washing place is provided.

  The bathtub fixture that can be adapted to the bathtub auxiliary tool of the present invention includes a first pressing portion as a clamp portion that presses on the surface from the washing area side, and a second pressing portion that presses on the surface from the bathtub side. If it has the press part, a commercially available fixture for bathtubs can be used without being specifically limited. For example, general-purpose bathtub fixtures such as a handrail for bathtubs and a transfer platform for bathing described in Patent Documents 1 to 6 described above can be used.

  In the bathtub auxiliary tool of the present invention, the pressure receiving force that causes the first pressing portion to abut on the washing area side in order to guide the pressing force transmitted from the first pressing portion of the bathtub fixing tool to the rim portion of the bathtub side wall. And an auxiliary pressing part that is brought into contact with the rim part of the bathtub side wall is attached to the leg part. The pressure receiving portion and the auxiliary pressing portion of the auxiliary tool for bathtubs can be manufactured using various materials without any particular limitation, and are known materials such as plastic materials, FRP, metal materials, wood, or a combination thereof. Can be used widely. In addition, rubber or the like made of a soft material such as rubber may be attached to the surface of the pressure receiving part or the auxiliary pressing part of the auxiliary tool for bathtubs in order to enhance the anti-slip function or the like, or a groove having unevenness. May be formed.

  In the auxiliary tool for bathtubs according to the present invention, the pressure receiving part attached to the leg part receives a pressing force by the first pressing part of the fixing tool for bathtubs, and therefore generates an appropriate frictional force with the first pressing part. It is preferable to have a size (area) to be applied, and it is more preferable to have a size (area) that can include the center point of the pressing surface of the first pressing portion. In particular, when the first pressing portion is supported by a main body frame, an arm, a bolt shaft, etc., the pressure receiving portion of the auxiliary tool for bathtubs has a connection point and a support point between the first pressing portion and the main body frame. It is preferable to have a size (area) that can be included.

  Here, the center point of the pressing surface of the pressing portion or the center point of the pressure receiving surface of the pressure receiving portion to be described later is, in principle, even if a load is applied to the pressing surface of the pressing portion or the pressure receiving surface of the pressure receiving portion. It means the point of action that does not rotate the pressure receiving part.For example, when the pressing part or pressure receiving part is supported by the main body frame, arm, bolt shaft, etc., it means the connection point and support point with the main body frame etc. To do. For this reason, when the pressing portion or the pressure receiving portion is attached to the main body frame or the like via a plurality of connection points and support points, the center point of the pressing surface of the pressing portion or the center point of the pressure receiving surface of the pressure receiving portion is the pressing portion. Even if a load is applied to the pressure surface or the pressure receiving surface of the pressure receiving portion, it means a linear action line or an action region having a certain range that does not rotate the pressing portion or the pressure receiving portion. In addition, when the pressing part or the pressure receiving part itself forms a part of a structure such as a frame and does not have a connection point or a supporting point for being supported by other parts, The center point of the pressing surface or the center point of the pressure receiving surface of the pressure receiving unit means the position of the center of gravity of the pressing surface or the pressure receiving surface.

  When the pressure receiving part of the auxiliary tool for bathtubs has a size (area) for generating an appropriate frictional force with the first pressing part of the fixing tool for bathtubs, the first pressing part and the bathtub use The pressing force of the first pressing portion can be reliably transmitted to the pressure receiving surface of the pressure receiving portion without causing a gap with the pressure receiving portion of the auxiliary tool. For this reason, the pressure receiving part of the auxiliary tool for bathtubs is sufficient if it has the magnitude | size which can fully contact with the 1st press part of the fixing tool for bathtubs as a rule, and the 1st press part of It may be larger or smaller than the size. Moreover, when the fixing tool for bathtubs is equipped with the some 1st press part on the washing-room side, the pressure receiving part of the auxiliary tool for bathtubs can be made to contact | abut them collectively simultaneously (area). It is preferable to have.

  Moreover, when the pressure receiving part of the auxiliary tool for bathtubs has a size (area) that can include the center point of the pressing surface of the first pressing part, the center point of the pressing surface of the first pressing part Is included in the pressure receiving surface of the pressure receiving portion, so that even if the first pressing portion is of a type in which the pressure receiving portion is pressed via an arm, a bolt shaft, or the like that supports the first pressing portion. A disadvantage that the rotational moment acts on the pressing portion and the first pressing portion is detached from the pressure receiving portion is prevented. For this reason, when the pressing part of the bathtub fixture is supported on an arm, a bolt shaft, etc. via two or more connection points, support points, etc., the pressure receiving part of the bathtub auxiliary tool It is preferable to have a size (area) that can simultaneously include the connection point and the support point.

  In general, the size of the pressure receiving part of the auxiliary tool for bathtubs is between the first pressing part (clamp part) of most bathtub fixing tools as long as it has a width of about 160 mm and a height of about 110 mm. An appropriate frictional force can be generated, and a connection point and a support point for supporting the first pressing portion can be included.

  Moreover, the pressure receiving part of the auxiliary tool for bathtubs can adjust the contact (contact) area with the first pressing part, or can include the center point of the pressing surface of the first pressing part. It is preferable that the height is adjustable to the leg portion of the bathtub auxiliary tool. The height adjusting means of the pressure receiving portion is not particularly limited, and a known technique can be adopted. For example, when the leg is in the shape of a cylindrical bar, the pressure receiving part is attached to a cylindrical sleeve slidably mounted on the outer peripheral surface of the leg, and the pin hole provided in the sleeve and the locking provided in the leg It can be configured by enabling screwing, insertion / removal with a locking pin, etc. at the slide position where the hole coincides.

  When the pressure receiving part is attached to the leg part so that the height can be adjusted, the first pressing part can be easily moved regardless of the position (height) of the first pressing part of the fixture for bathtub. This is convenient because it can be adjusted so as to contact the pressure receiving portion.

  In the auxiliary tool for bathtubs of the present invention, the auxiliary pressing part attached to the leg part in the direction opposite to the pressure receiving part transmits the pressing force transmitted from the first pressing part of the bathtub fixing tool to the pressure receiving part. In order to concentrate and transmit to the part, it is preferable to have a size (area) and shape that can be brought into contact with only the rim part.

  When the auxiliary pressing part of the bathtub auxiliary tool has a size (area) and shape that can be brought into contact with only the rim part of the bathtub side wall, an appropriate frictional force is generated between the auxiliary pressing part and the rim part. Accordingly, the pressing force of the first pressing portion transmitted to the auxiliary pressing portion is reliably transmitted only to the rim portion of the bathtub side wall without causing a gap between the rim portion and the auxiliary pressing portion of the auxiliary tool for bathtub. be able to. That is, since the clamping force brought about by the first pressing portion of the bathtub fixture is transmitted only to the rim portion of the bathtub side wall via the pressure receiving portion and auxiliary pressing portion of the bathtub auxiliary tool of the present invention, the bathtub apron, etc. The fragile bathtub side wall is not damaged.

  In general, the size of the auxiliary pressing part of the auxiliary tool for bathtubs has a width of about 160 mm and a height of about 20 mm. The pressing force of the fixture for bathtub can be transmitted only to the part.

  Further, the auxiliary pressing portion of the bathtub auxiliary tool may be attached to the leg portion of the bathtub auxiliary tool so as to be adjustable in height so that the position of contact (contact) with the rim portion of the bathtub side wall can be adjusted. preferable. The height adjusting means of the auxiliary pressing portion is not particularly limited, and a known technique can be adopted. For example, if the leg is a cylindrical rod, the auxiliary pressing part is attached to a cylindrical sleeve slidably mounted on the outer peripheral surface of the leg, and the pin hole provided in the sleeve and the engagement provided in the leg It can be configured by enabling screwing, insertion / removal with a locking pin, and the like at the slide position where the stop hole coincides.

  If the auxiliary pressing part is attached to the leg part so that the height can be adjusted, the auxiliary pressing part can be easily applied only to the rim part regardless of the position (height) of the rim part of the bathtub side wall. This is convenient because it can be placed in contact.

  Thus, the bathtub auxiliary tool of the present invention is usually a bathtub for a unit bath including a rim portion having strength and an apron portion not having strength attached to the lower portion thereof. The pressing force of the 1st press part of the fixing tool for bathtubs which clamps the apron part of a side wall can be guide | induced to only the rim part of the bathtub side wall formed in the upper part of the apron part.

  For this reason, as for the auxiliary tool for bathtubs of this invention, the pressure receiving surface of the pressure receiving part that receives the pressing force of the first pressing part transmits the pressing force of the first pressing part transmitted to the pressure receiving surface only to the rim part. It has the characteristic that it is arrange | positioned in the position relatively lower than the press surface of an auxiliary press part. In other words, the pressing surface of the auxiliary pressing portion is disposed at a position relatively higher than the pressure receiving surface of the pressure receiving portion.

  In other words, in the bathtub auxiliary tool of the present invention, the center point of the pressure receiving surface of the pressure receiving portion that receives the pressing force of the first pressing portion rims the pressing force of the first pressing portion transmitted to the pressure receiving surface. It has the characteristic that it is arrange | positioned in the position lower in the perpendicular direction than the center point of the press surface of the auxiliary | assistant press part which transmits only to a part. In other words, the center point of the pressing surface of the auxiliary pressing portion is arranged at a position higher in the vertical direction than the center point of the pressure receiving surface of the pressure receiving portion.

  Further, in general, in a general-purpose bathtub fixing tool, each of the first pressing portion that functions as a washing portion-side clamp portion and the second pressing portion that functions as a bathtub-side clamping portion has a pressing surface or a center point thereof. It is designed so as to be arranged at a substantially opposite position across the bathtub side wall. For this reason, when the auxiliary tool for bathtubs of the present invention is used for attaching the fixing tool for bathtubs, the pressing force of the first pressing portion is attached to the vertical direction or a relatively higher position than that. Therefore, the pressing surface of the auxiliary pressing portion or the center point thereof is disposed at a position that is relatively higher in the vertical direction than the pressing surface of the second pressing portion of the bathtub fixture or the center point thereof. It has the characteristics.

  In other words, the bathtub auxiliary tool of the present invention is a unit bath provided with a narrow rim portion in the height direction and a wide apron portion attached to the lower portion of the rim portion. Normally, the pressing force of the first pressing part of the bathtub fixing tool that clamps the apron part that occupies most of the bathtub side wall is concentrated only on the rim part that only occupies the upper part of the bathtub side wall. Can be made. For this reason, as for the auxiliary tool for bathtubs of this invention, the pressure receiving area of the pressure receiving part which receives the pressing force of a 1st press part transmits the pressing force of the 1st pressing part transmitted to the pressure receiving surface only to a rim | limb part. It has the feature that it is larger than the pressing area of the auxiliary pressing part. In other words, the pressing area of the auxiliary pressing part is smaller than the pressure receiving area of the pressure receiving part.

  In general, in general-purpose bathtub fixtures, the center of each pressing surface of the first pressing portion that functions as a clamp portion on the washing station side and the second pressing portion that functions as a clamping portion on the bathtub side is the bathtub. In many cases, it is designed to have substantially the same pressing area so that it can be disposed at substantially opposite positions across the side wall. For this reason, when the auxiliary tool for bathtubs of the present invention is used for attaching the fixing tool for bathtubs, the pressing force of the first pressing part is concentrated on the auxiliary pressing part having a narrower width in the height direction than the first pressing part. Therefore, the pressing area of the auxiliary pressing portion is relatively smaller than the pressing area of the second pressing portion of the bathtub fixture.

  In the bathtub auxiliary tool of the present invention, a leg portion that supports the pressure receiving portion and the auxiliary pressing portion and whose lower end is in contact with the floor surface of the washing place is provided. The leg portion generates a rotational moment generated by a displacement between a pressing point by the pressure receiving portion of the bathtub auxiliary tool on the washing place and a pressing point by the second pressing portion of the bathtub fixing tool on the bathtub side, Installed to support the surface.

  The legs can be manufactured using various materials without any particular limitation, and a wide variety of known materials such as plastic materials, FRP, metal materials, wood, or a combination thereof can be used. However, the leg part is a part that supports the pressure receiving part and the auxiliary pressing part on the side of the washing place where various chemicals such as soap, shampoo and detergent are used, so it has chemical resistance, corrosion resistance and high strength. It is preferred to use a metallic material such as, for example, coated iron, stainless steel, aluminum. Further, the shape of the leg portion is not particularly limited, and may be a rod shape having a cross section such as a circle, an ellipse, a square or a rectangle, or a plate shape having a lateral width substantially equal to the pressure receiving portion or the auxiliary pressing portion. It may be.

  Moreover, it is preferable that the leg part is provided with the expansion-contraction means which can adjust the height. When the height of the leg portion is adjustable, the fitting range of the bathtub fixture and the unit bath that can use the bathtub auxiliary tool of the present invention is widened. In addition, when the relative positional relationship between the pressure receiving portion and the auxiliary pressing portion is determined, the height of the pressure receiving portion and the auxiliary pressing portion can be adjusted to the bathtub fixture and the unit bath in one operation without adjusting the height of each. Since it can be adapted, the set of auxiliary equipment for bathtubs is facilitated.

  The leg expansion / contraction means is not particularly limited, and a known technique can be employed. For example, when the leg part is a cylindrical bar, the leg part is divided into an outer cylinder and an inner cylinder that is slidably inserted into the outer cylinder. Thus, the expansion / contraction means can be configured by providing a rotating part that can reduce or increase the diameter of the insertion opening of the outer cylinder. In the case of this configuration, by pulling out the inner cylinder from the outer cylinder, the pressure receiving portion and the auxiliary pressing portion can be simultaneously adapted to the bathtub fixture and the unit bath.

  In the bathtub auxiliary tool of the present invention, the leg portion includes a contact portion that can be brought into contact with the wash-basin side wall of the bathtub by adjusting the protruding length from the leg portion in a substantially horizontal direction. It is preferable. Further, the shape and material of the abutting part are not particularly limited as long as they can be protruded from the leg part toward the washing side wall of the bathtub, and are not limited to a bar shape, a plate shape, a U shape, and a U shape. A known material having a shape such as a letter shape, or a metal material, FRP, a plastic material, or a combination thereof can be used.

  When the bathtub auxiliary tool of the present invention is used for attaching the bathtub fixing tool, as described above, the center point of the pressing surface of the auxiliary pressing portion is relatively that of the pressing surface of the second pressing portion of the bathtub fixing tool. Since it is arranged at a position that is higher in the vertical direction than the center point, the tub fixture attached to the tub side wall via the tub auxiliary tool has a difference in the position of the pressing point on the tub side and the tub side. A rotating moment that rotates toward the side works. For this reason, in the auxiliary tool for bathtubs of this invention, while providing the leg part made to contact | abut to the floor surface of a washing place, and also providing the contact part to contact the bathtub side wall by the side of a washing place, it is for bathtubs. It is comprised so that the rotational moment which rotates an auxiliary tool and the fixing tool for bathtubs toward the washing-room side can be negated.

  In particular, the rotational moment that rotates the bathtub auxiliary and the bathtub fixture toward the washing area is also transmitted to the leg, so that the leg is compressed between the pressure-receiving surface and the floor of the washing area. As a result, a rotational moment is applied that moves the lower end of the leg portion toward the side wall of the bathtub. For this reason, in the auxiliary tool for bathtubs of this invention, the lower end of a leg part faces the side wall of a bathtub by providing the contact part which can be made to contact | abut the strength part of a bathtub side wall in the lower end vicinity of a leg part. The approach (rotation) is prevented and the inconvenience that the auxiliary tool for bathtubs and the fixing tool for bathtubs rotate toward the washing place side is prevented.

  In addition, as for the contact part attached to a leg part, the closer the attachment position is to the lower end of a leg part, the more effectively, the inconvenience that the auxiliary tool for bathtubs and the fixing tool for bathtubs rotate toward the washing place side. Can be prevented. Also, generally, the lower part of the side wall of the unit type bathtub has strong strength to induce drainage on the washing side and support the apron part from below, and forms part of the bathtub side wall and floor surface. A waterproof pan is formed (see Patent Document 7). Also from this point of view, the abutting portion attached to the leg portion has a protruding length from the leg portion in the substantially horizontal direction in the vicinity of the lower end of the leg portion so as to be surely brought into contact with the waterproof pan on the bathtub side wall. It is important to be able to adjust.

  In addition, a wedge-shaped elastic stopper that decreases in thickness from the washing-side side wall of the bathtub toward the leg may be provided at the lower end of the leg to prevent the lower end of the leg from shifting on the floor surface of the washing area. Good. If a wedge-shaped elastic stopper is provided at the lower end of the leg part, the lower end of the leg part tends to approach the side wall of the bathtub due to the rotational moment generated by the displacement of the pressing point on the washing area side and the bathtub side. ), The lower end of the leg part moves on the top surface of the wedge-shaped elastic stopper in the direction of increasing the height, so that a compressive force is generated in the leg part, and the movement (displacement) of the leg part does not occur. Be blocked.

  In addition, when the wedge-shaped elastic stopper is firmly fixed to the lower end of the leg, the lower end of the leg and the side of the washing area become closer as the lower end of the leg approaches the side wall of the bathtub. Therefore, it is preferable that the shape of the elastic stopper is a wedge shape whose thickness increases in the direction from the washing side wall of the bathtub toward the leg portion in the opposite direction to that described above.

  As described above, the shape of the leg portion is not particularly limited. For example, in the case of a rod shape, the leg portion is preferably made of a pair of rod-shaped members. When the legs are made of a pair of rod-like members, the strength of the bath aids as a whole can be increased as a structure, or the bath aids can stand on the floor at the washroom side when installing the bath fixtures. It becomes possible to attach to the bathtub side wall of the fixture for bathtubs.

  In addition, when the leg portion is made of a pair of rod-shaped members, the abutment portion attached near the base of the leg portion is adjusted in the substantially horizontal direction by adjusting the protruding length from the leg portion, so that the washing room side of the bathtub If it can be brought into contact with the side wall, for example, a U-shaped or U-shaped shape having a bottom side (bottom) toward the bathtub side wall or a U-shaped shape or a plate-like shape, the pair of rod-shaped members are mutually connected. It is preferable that they are connected. When the pair of leg portions are connected to each other using the contact portion, the strength of the bathtub auxiliary tool as a whole is further enhanced as a structure, and unnecessary parts are replenished by diverting the contact portion. Therefore, it is possible to achieve slimming, miniaturization, etc. of the auxiliary tool for bathtubs.

  According to this invention, the auxiliary tool for bathtubs of this invention is attached to the attachment of the general purpose bathtub fixing tool provided with one clamp part pressed on the surface from the washing-room side and the other clamp part pressed on the surface from the bathtub side. When used, the pressing force of the clamp part on the washing area side is accurately applied to the strength part (rim part) of the bathtub side wall, even in the case of a bathtub side wall having an outer wall provided with a strong rim part and a non-strength apron part. And the rotational moment generated by the displacement of the positions of the pressing points on the washing place side and the bathtub side can be canceled out, so that the bathtub fixture can be securely and firmly attached to the bathtub side wall.
