Hereinafter, embodiments of the present invention will be described. In the following embodiment, a bathroom handrail will be used as an example of the load receiving member, and a bracket for attaching the handrail to the bathroom will be used as a bracket for detailed description. In addition to the handrail for the bathroom, the bracket of the present invention can also be used for attaching a load receiving member such as a slide bar for holding a shower head and a handrail in a corridor of a house. The load receiving member is a long body such as a handrail or a slide bar, and has a role of receiving a load applied by an article such as a shower head or a user.

FIG. 1 is a perspective view showing a bathroom unit to which the bracket according to the first embodiment is applied. The bathroom unit 1 includes a bathtub 10, a washing place 12, an apron 14 that is a boundary between the bathtub 10 and the washing place 12, a bathroom wall portion 16, a mirror 18 attached to the bathroom wall portion 16, and a counter 20 attached to the bathroom wall portion 16. , A handrail 22 attached to the bathroom wall 16, a shelf 24 for placing small items such as shampoo, a shower head 26, and a faucet device 28.

The bathtub 10 has a deep dish shape in which hot water can be stored. The washing place 12 is provided at a position adjacent to the bathtub 10, and has a certain size so that the user can wash his / her body. The bathtub 10 and the washing place 12 are surrounded by the bathroom wall portion 16 and are arranged in the closed space formed by the bathroom wall portion 16. The apron 14 covers the side surface of the bathtub 10 on the washing place 12 side and is located at the boundary between the bathtub 10 and the washing place 12.

The mirror 18 is arranged so as to face the bathtub 10 and the washing place 12 across one wall portion 16a of the bathroom wall portions 16 forming the closed space. The counter 20 is arranged so as to project horizontally from the wall portion 16a toward the washing place 12 at substantially the same height as the upper surface of the bathtub 10.

The handrail 22 extends across the wall portion 16a so as to project from the wall portion 16a toward the bathtub 10 and the washing place 12. The height at which the handrail 22 is attached is preferably between the mirror 18 and the counter 20 so that the user can move from the washing place 12 into the bathtub 10 and hold it until he / she sits in the bathtub 10. The handrail 22 is attached to the wall portion 16a between the handrail 22 and the surface of the wall portion 16a so that the distance overhanging from the wall portion 16a changes depending on the location. More specifically, the distance between the handrail 22 and the wall portion 16a is relatively short on the bathtub 10 side and relatively long on the washing place 12 side. Therefore, the handrail 22 has a curved shape that projects horizontally toward the washing place 12 in the vicinity of the washing place 12. A shelf 24 is arranged between the handrail 22 and the wall portion 16a at a position where the distance between the handrail 22 and the wall portion 16a is relatively long. Such a handrail 22 is fixed to the surface of the wall portion 16a by a plurality of support members 30. The details of the support member 30 will be described later.

The bottom surface of the shelf 24 has a mesh shape so that small items such as shampoo can be placed on the top surface without collecting water.

The shower head 26 is supported by a hook 34 that can move along a slide bar 32 fixed to the wall portion 16a. The slide bar 32 is a rod-shaped member extending in the vertical direction and is fixed to the surface of the wall portion 16a. The hook 34 is configured to be slidable in the vertical direction along the slide bar 32 and to be engaged with the slide bar 32 at a predetermined height.

The faucet device 28 is provided on the wall portion 16a facing the washing place 12, and is located between the counter 18 and the handrail 20. The faucet device 28 is used to control the flow rate of water discharged from the shower head 26 and the temperature of water discharged.

FIG. 2 is an exploded perspective view of the support member. As shown in FIG. 2, the support member 30 includes a first bracket cover 36, a second bracket cover 38, and a bracket 40. In the present embodiment, the handrail 22 is curved in a horizontal plane, and the distance between the handrail 22 and the wall portion 16a differs depending on the position of the handrail 22 in the axial direction. Therefore, the axial length of the support member 30 for attaching the handrail 22 to the wall portion 16a differs depending on the individual support members. In the following, the configuration of the support member 30 in which the distance between the handrail 22 and the wall portion 16a is the longest will be described in detail, but the remaining support members may have the same configuration.

The first bracket cover 36 and the second bracket cover 38 cover the bracket 40 to improve the design of the entire bracket 40. More specifically, the first bracket cover 36 has an angular C-shaped cross section that opens upward, and the second bracket cover 38 has a cross-sectional shape that opens downward. The first bracket cover 36 and the second bracket cover 38 are slidable with respect to the bracket 40 from the axially opposite sides of the bracket 40, respectively. By sliding the first bracket cover 36 with respect to the bracket 40 from one side, the first bracket cover 36 covers the lower side of the bracket 40. Further, by sliding the second bracket cover 38 with respect to the bracket 40 from the other side, the second bracket cover 38 covers the upper side of the bracket 40. By locking the locking portion 36a of the first bracket cover 36 and the locking portion 38a of the second bracket cover 38 to each other, the first bracket cover 36 and the second bracket cover 38 can be integrated. The first bracket cover 36 and the second bracket cover 38 can be formed of, for example, a plated resin material or a metal material.

3 is a side view of the bracket, FIG. 4 is a front view of the bracket as viewed from the washing area side, FIG. 5 is a rear view of the bracket from the wall side, and FIG. 6 is a rear view of the bracket. 6-6 is a cross-sectional view of the above, and FIG. 7 is a bottom view of the bracket.

The bracket 40 has a shape extending from the surface of the wall portion 16a toward the tip on the washing place 12 side. A mounting surface 42 for mounting on the wall portion 16a is formed on the first end portion 40a of the bracket 40. A handrail 22 is attached to the second end 40b of the bracket 40 on the side opposite to the first end. Hereinafter, the configuration of such a bracket 40 will be described in more detail.

As shown in FIGS. 3 to 7, the second end 40b of the bracket 40 has a curved surface 44 that fits the outer shape of the handrail having a round cross section. A hole 44a for fixing the handrail 22 is formed on the curved surface 44 of the bracket 40.

The mounting surface 42 of the bracket 40 is formed substantially flat so as to be in close contact with the surface of the flat wall portion 16a. In particular, as shown in FIG. 5, the lower portion 42a of the mounting surface 42 is wider than the upper portion 42b of the mounting surface 42. By adopting the shape of the mounting surface 42 of the bracket 40, it is possible to make the upper side of the bracket 40, which is easier to see, look thinner while securing the area of the mounting surface 42. The mounting surface 42 is provided with two holes 42c arranged in the vertical direction so that the bracket 40 can be mounted on the wall portion 16a via a fixing means such as a screw.

Further, as shown in FIGS. 4, 6 and 7, the bracket 40 is opened downward, and a hollow portion H is formed inside the bracket 40. More specifically, the bracket 40 has an intermediate portion 46 extending from the first end portion 40a to the second end portion 40b along the extending direction of the bracket 40 and having a hollow structure. The hollow portion H has substantially the same length as the direction in which the intermediate portion 46 extends, and the intermediate portion 46 has a hollow structure due to the presence of the hollow portion H. The pair of side walls 50 have a substantially uniform wall thickness over the entire length of the bracket 40. Further, the pair of side walls 50 are arranged side by side in the width direction of the bracket 40 orthogonal to the extending direction of the bracket 40 so that the inner surfaces of the pair of side walls 50 face each other. Further, the pair of side walls 50 extend in parallel and in a straight line from the first end 40a to the second end 40b. Further, the inner surfaces of the pair of side walls 50 have a planar shape. As a result, the hollow portion H has the same width from the first end portion 40a to the second end portion 40b. When the bracket 40 having such a configuration is viewed from the bottom surface, the hollow portion H and the inner surfaces of the pair of side walls 50 do not have bending points. By adopting a linear structure in which the hollow portion H and the side wall 50 do not have a bending point, stress is prevented from being concentrated at a specific position of the side wall 50 when a load is applied to the bracket 40 from above. be able to. It is optional that the inner surface of the side wall 50 has a structure having no bending point, and when the bracket 40 has a reinforcing structure described later, the inner surface of the side wall 50 is curved or the bending point. It may have a shape having.

Further, a plurality of ribs 52 as a reinforcing structure are provided on the outer surfaces of the pair of side walls 50, respectively. The rib 52 is erected in a direction orthogonal to the outer surface of the side wall 50, and extends from the vicinity of the first end portion 40a toward the second end portion 40b. The ribs 52 are arranged at equal intervals on the lower side of the outer surface of each side wall 50 when the bracket 40 is viewed from the side. That is, looking at the relationship between the position of the rib 52 and the mounting surface 42, the rib 52 is formed over a vertical range corresponding to the lower portion 42a of the mounting surface 42, but the upper portion 42b of the mounting surface 42 It is not formed over the vertical range corresponding to. Therefore, when the bracket 40 is viewed from the side in the width direction, the rib 52 is provided only on the lower side of the side wall 50, and is not provided on the upper side. The end of the rib 52 on the first end 40a side is connected to the back surface of the wide lower half 42a of the mounting surface 42. In this way, by arranging the rib 50 at a position where stress is likely to be concentrated when a load is applied to the bracket 40, it is possible to prevent the side wall 50 of the bracket 40 from being deformed inward (hollow portion H side). can do. Further, by providing the rib 52 only on the lower side of the side wall, the appearance of the upper portion of the intermediate portion 46 becomes neat, and good design can be obtained. In the present embodiment, four ribs 52 are provided on each of the pair of side walls, but the number and size of the ribs 52 can be changed as appropriate.

Further, as shown in FIG. 3, the height of the side wall 50 gradually increases from the second end portion 40b of the bracket 40 toward the first end portion 40a, so that the shape of the angular C-shaped cross section is the first. It differs from the end 40a to the second end 40b. However, when comparing the external dimensions of the mounting surface 42 with the external dimensions of the bracket 40 in the intermediate portion, the external dimensions of the mounting surface 42 are larger than the external dimensions of the bracket 40 at all positions.

FIG. 8 is a schematic view showing the relationship between the external dimensions of the mounting surface and the intermediate portion. The external dimensions of the intermediate portion 46 having a square C-shaped cross section are virtual lines A connecting the tips of the free ends of the pair of side walls 50 forming the square C-shape in the cross section in the width direction of the bracket 40 (FIG. 6), and the external dimensions of the region S1 surrounded by the outer surfaces of the pair of side walls 50 and the upper surface of the upper wall 48. In other words, the region S1 is a region surrounded by the outer shape of the cross section of the intermediate portion 46 and the virtual line A when the cross section of the intermediate portion 46 is taken in the width direction of the bracket 40 and the virtual line A is drawn. The external dimensions of the region S1 refer to the dimensions of the maximum width W1 of the region S1 which is the dimension along the width direction of the bracket 40 and the dimension of the maximum height H1 which is the dimension along the vertical direction of the bracket 40. The external dimensions of the mounting surface 42 refer to the maximum width W2 of the mounting surface 42, which is the dimension along the width direction of the bracket 40, and the maximum height H2, which is the dimension along the vertical direction of the bracket 40. In FIG. 8, the area S1 is a shaded area. The external dimension of the mounting surface 42 is larger than the external dimension of the region S1 means that at least the maximum width W2 of the mounting surface 42 is larger than the maximum width W1 of the region S1 and the maximum height H2 of the mounting surface 42 is the region S1. It means that it is the same as or larger than the maximum height H1 of. In the example of FIG. 8, since the height H2 of the external dimensions of the mounting surface 42 is larger than the height H1 of the region S1 and the width W2 of the mounting surface 42 is larger than the width W1 of the region S1, the mounting surface 42 The external dimensions of are larger than the region dimensions of the region S1. Further, since the external dimension of the mounting surface 42 is larger than the external dimension of the region S1, in many cases, the support member 30 has a substantially T-shape when the support member 30 is viewed from above. By making the external dimensions of the mounting surface 42 larger than the external dimensions of the region S1 surrounded by the angular C shape, it is easy to secure the area of the mounting surface 42 to which the load is applied while making the entire bracket 40 look thin. Can be done.

Next, the operation of the support member 30 will be described.

For example, when the user moves from the washing place 12 to the bathtub 10, he / she moves while grasping the handrail 22. At this time, a load in the vertical direction is applied to the handrail 22, and a load in the vertical direction is applied to the second end portion 40b of the support member 30. As a result, a force is applied to the mounting surface 42 of the bracket in the direction in which the upper portion 42a of the mounting surface 42 is separated from the wall portion 16a and in the direction in which the lower portion 42b of the mounting surface 42 is pressed against the wall portion 16a. Since the lower portion 42b of the mounting surface 42 is formed wider than the upper portion 42a of the mounting surface 42 and has a relatively large area, the force applied to the lower portion 42b of the mounting surface 42 can be dispersed.

Further, the pair of side walls 50 of the bracket 40 have a linear shape having no bending point when viewed from the bottom surface side. Due to the structure having no bending point, even if stress is applied from the upper surface of the bracket 40 to the in-plane direction of the side wall 50, the stress is not concentrated on a part of the side wall 50, and the inside of the bracket 40 (hollow portion). Deformation to the H side) can be suppressed. Further, by forming the rib 52 as a reinforcing structure on each of the pair of side walls 50 in addition to the structure of the side wall 50, the strength of the side wall 50 can be further improved, and the side wall 50 can be moved to the hollow portion H side. Deformation can be suppressed.

Next, a second embodiment of the present invention will be described. FIG. 9 is a perspective view of the bracket according to the second embodiment. The bracket 70 according to the second embodiment has ribs 72 formed on the inner surface of the side wall 50 instead of the ribs 52 formed on the outer surface of the side wall 50.

As shown in FIG. 9, a plurality of ribs 72 extending in a substantially horizontal direction are provided on the inner surface of the side wall 50 of the bracket 70 as a reinforcing structure. The bracket 70 has the same number of ribs 72 on the inner surfaces of each of the pair of side walls 50. In the example shown in FIG. 9, the side wall 50 is provided with four ribs 72 extending in the horizontal direction. The rib 72 extends from the inner surface of the side wall 50 to the back surface of the mounting surface 42. The position where the rib 72 is provided is preferably a position where stress is likely to be concentrated when a load is applied to the handrail 22, that is, near the mounting surface 42 of the support member 30. Further, among these, since stress is most likely to be concentrated at the position of the side wall 50 downward in the vertical direction, the rib 72 is formed over the vertical range corresponding to the lower portion 42a of the mounting surface 42, but the mounting surface. It is not formed over the vertical range corresponding to the upper portion 42b of 42.

As described above, by providing the rib 72 on the side wall 50 of the bracket 70 as the reinforcing structure, it is possible to suppress the side wall 50 from being deformed inward (on the hollow portion H side). The reinforcing structure of the bracket 70 according to the second embodiment may be applied together with the rib 52 which is the reinforcing structure of the support member 30 according to the first embodiment, or may be applied separately. ..

Deformation of the side wall 50 can also be suppressed by providing the rib 72 as a reinforcing structure on the inner surface of the side wall 50 in this way. The rib 52 of the side wall 50 shown in FIGS. 3 to 7 and the rib 72 of the side wall 50 shown in FIG. 9 can also be used in combination. When the ribs 52 and 72 are provided on the outer surface and the inner surface of the side wall 50, respectively, the number of ribs that can be seen from the outside can be reduced.

FIG. 10 shows a bottom view of the bracket according to a modified example of the first embodiment. As shown in FIG. 10, the bracket 80 is provided with a reinforcing structure 82 in which the thickness of the side wall 50 gradually increases as it approaches the first end portion 40a instead of the rib 52. The reinforcing structure 82 is preferably formed so that the outer surfaces of the pair of side walls 50 are curved and the outer surfaces of the side walls 50 are separated from each other. In this way, by changing the thickness of only the lower side of the side wall 50 in the vicinity of the first end 40a of the bracket 80, the deformation of the side wall 50 to the inside (hollow portion H side) can be suppressed. In the example of FIG. 10, only the outer surface of the side wall 50 is curved to increase the thickness of the side wall 50, but only the inner surface of the side wall 50 may be curved to increase the thickness of the side wall 50. ..

As a further modification, as the reinforcing structure, in addition to the above-mentioned structure in which the thickness of the rib 52, the rib 72, and the side wall gradually increases, the side walls may be connected to each other by a rod or the like. With such a structure, it is possible to prevent the side wall 50 from being deformed inward (on the hollow portion H side). Further, in the above-described embodiment, the cross-sectional shape of the intermediate portion 46 of the bracket is a square C-shape with an opening on the lower side, but a closed cross section may be used.

The embodiments and modifications of the present invention have been described in detail above. The above-described embodiments and modifications are merely specific examples for carrying out the present invention. The contents of the embodiments and modifications do not limit the technical scope of the present invention, and many design changes such as modification, addition, and deletion of components can be made without departing from the idea of the invention. The hatching attached to the cross section of the drawing does not limit the material of the object to which the hatching is attached.

Generalization of the invention embodied by the above embodiments and modifications leads to the following technical ideas. Hereinafter, the aspects described in the problem to be solved by the invention will be described.

In the first aspect, the bracket of the second aspect is a rib provided on the side wall of the intermediate portion along the extending direction of the intermediate portion.

According to such a configuration, the reinforcing structure can be realized by the ribs having a relatively clean appearance. Further, for example, by adopting a rib formed on the outer surface of the side wall, the moldability of the bracket can be improved.

In the first or second aspect of the bracket of the third aspect, the reinforcing structure is provided only in the lower portion of the intermediate portion.

According to such a configuration, since the reinforcing structure is provided only on the lower portion of the intermediate portion, the appearance of the upper portion of the intermediate portion is neat and good designability can be obtained.

In the first aspect of the bracket of the fourth aspect, the inner surfaces of the pair of side walls have a planar shape along the extending direction of the intermediate portion.

According to such a configuration, the strength of the side wall can be improved by the structure of the side wall itself, and the side wall can be suppressed from being deformed toward the hollow portion.
