Hereinafter, a handrail structure according to a first embodiment of the present invention will be described with reference to the accompanying drawings.
1 is a perspective view showing a handrail according to the first embodiment of the present invention, FIG. 2 is an exploded perspective view of a joint portion of the handrail according to the first embodiment of the present invention, and FIG. 3 is a first embodiment of the present invention. It is a perspective view of the joint part of the handrail by a form, and FIG. 4 is a center sectional view of the joint part of the handrail by 1st Embodiment of this invention.

  As shown in FIGS. 1 to 4, the handrail 1 is a handrail fixed to the wall surface W, and in particular, a handrail provided in a water environment such as a toilet, a washstand, and a bathroom. The handrail 1 includes a bar member 2 that extends along the wall surface W at a position spaced from the wall surface W, and a joint portion 4 that fixes the bar member 2 to the wall surface W. The bar member 2 forms a grip bar that is gripped by the user.

The joint portion 4 of the handrail 1 will be described in detail with reference to FIGS.
The joint portion 4 includes a metal flange 6 that is formed so as to extend along the wall surface W and is fixed to the wall surface W, a first core member 8 that is fixed to the flange 6, and a first core member 8. A case 10 for covering, a flange cover 12 for covering the flange 6, and a second core member 14 extending into the bar member 2 are provided.
The bar member 2 side viewed from the flange 6 of the handrail 1 is the front side, the wall surface W side viewed from the flange 6 is the rear side, the center side of the flange 6 is the inner side, and the radial direction with respect to the center side of the flange 6 The opposite side is described as the outside.

  The flange 6 is a member that spreads in a collar shape. The flange 6 includes a plate portion 6a that is formed in an annular shape and formed in a flat plate shape. The plate portion 6a is formed with an inner peripheral opening 6b inside the plate portion 6a. The plate portion 6a is further formed with a hole 6c through which a screw 15 for fixing the flange 6 to the wall surface W is inserted. The plate portion 6a is fixed in a state where the plate portion 6a is arranged in a direction along the wall surface W by inserting the screw 15 into the hole 6c. The flange 6 may be formed in a shape that does not follow the wall surface W, for example, a mount-type flange shape, and may be fixed to the wall surface W.

  The first core member 8 is welded and fixed to the inner peripheral opening 6b of the plate portion 6a. The first core member 8 is a cylindrical member and is a metal pipe. The first core member 8 can be formed to an arbitrary length by cutting a long general-purpose stainless steel pipe. For this reason, the 1st core material 8 is very easily formed in arbitrary length, and length adjustment is very easy. The first core member 8 is disposed so as to rise from the flange 6 toward the bar member side. The first core member 8 extends in the vertical direction with respect to the wall surface W. The first core member 8 extends so as to rise from the flange 6. In the handrail 1, the distance L1 from the wall surface W of the bar member 2 can be adjusted by changing the length L2 rising from the flange 6 of the first core member 8. The distance L1 is a so-called dimension from the wall surface W of the bar member 2. Specifically, the distance L1 is a distance from the wall surface W to the axis of the bar member 2. By adjusting the length L2 of the first core member 8 to an arbitrary length, the distance L1 can be adjusted to an arbitrary length.

  A hole 8 a is formed in the front side portion of the first core member 8. The hole 8a is slightly smaller than the outer diameter of the second core member 14 so that the first core member 8 and the second core member 14 are fixed in a state where the second core member 14 is press-fitted. It is formed in size.

The case 10 is made of resin and forms an exterior member between the bar member 2 and the flange cover 12. The case 10 is formed outside the first core member 8. The case 10 is curved toward the bar member 2 on the front side from the front end of the first core member 8 and the first straight pipe portion 10a in a direction linearly rising from the flange cover 12 along the first core member 8. And a second straight pipe portion 10c extending linearly toward the bar member 2.
The first straight pipe portion 10a of the case 10 is formed to have a predetermined length L3. When the distance L4 from the flange cover 12 to the bar member 2 is shorter than the length L3, the case 10 accommodates the first core member 8 therein without adding an extension case 111 described later. The distal end portion of the second straight pipe portion 10 c forms a connection portion that is connected to the bar member 2 while being inserted into the bar member 2.

  The case 10 covers the first core member 8 and configures the appearance of the joint portion 4. The case 10 can be formed separately from the first core member 8 that requires strength. Since the case 10 can be formed with relatively low strength, the thickness of the case 10 can be reduced, and the manufacturing cost of the case 10 can be reduced. For example, the case 10 can be formed of a general-purpose resin material other than engineering plastic, and the manufacturing cost of the case 10 can be reduced. Furthermore, the case 10 can also be formed of a resin material having high design properties, for example, a glossy resin material or a resin material with added color. The choice of the resin material which forms case 10 can be increased, and the choice of appearance selection of case 10 can be increased. Note that the case 10 may be formed of engineering plastic.

  As shown in FIG. 4, the flange cover 12 is formed in a cylindrical cap shape. The flange cover 12 forms a cover that covers the front side and the outside of the flange 6. The flange cover 12 forms an opening 12a in which the first core member 8 is disposed inside. The opening 12a is formed in a circular shape. The opening 12 a forms a gap between the first core member 8 and the end 10 d of the case 10 disposed outside the first core member 8. The opening 12 a forms an inner diameter larger than the outer diameter of the first straight pipe portion 10 a of the case 10. The amount of insertion of the end 10d of the case 10 into the opening 12a is variable. By adjusting the amount of insertion of the end portion 10d of the case 10 into the flange cover 12, the distance L1 from the wall surface W of the bar member 2 and the distance L5 protruding from the wall surface of the case 10 of the joint portion 4 can be adjusted. It is said that.

  The flange cover 12 covers the flange 6 and constitutes the appearance of the joint portion 4. The flange cover 12 can be formed separately from the first core member 8 and the flange 6 that require strength. Since the flange cover 12 can be formed with relatively low strength, the resin thickness of the flange cover 12 can be reduced, and the manufacturing cost of the flange cover 12 can be reduced. Further, the flange cover 12 can be formed of a general-purpose resin material other than engineering plastic, and the manufacturing cost of the flange cover 12 can be reduced. Furthermore, the flange cover 12 can be formed of a resin material with high design properties, for example, a glossy resin material or a resin material with added color. The choice of the resin material which forms the flange cover 12 can be increased, and the choice of the appearance selection of the flange cover 12 can be increased. The flange cover 12 may be made of engineering plastic.

  The second core member 14 is a cylindrical member and is a metal pipe. The second core member 14 can also be formed by cutting a general-purpose stainless steel pipe. The second core material 14 is fixed to the first core material 8. The second core member 14 is firmly fixed to the first core member 8 by being press-fitted into the hole 8 a formed in the first core member 8. The second core member 14 is disposed in a direction orthogonal to the first core member 8 and extends substantially parallel to the wall surface W. The second core member 14 is disposed in the second straight pipe portion 10c. The second core member 14 is disposed as the central axis of the connection portion with the bar member 2 and reinforces the structures of the bar member 2 and the joint portion 4. Further, since the second core member 14 is firmly fixed to the first core member 8, the strength of the joint portion 4 as a whole that bends toward the bar member 2 can be improved. Furthermore, the connection portion between the bar member 2 and the joint portion 4 is reinforced, and the strength in the vicinity of the connection portion between the bar member 2 and the joint portion 4 can be improved. That is, the load resistance of the connection portion between the bar member 2 and the joint portion 4 is improved.

Next, with reference to FIG. 5, a joint portion of a modification of the handrail according to the first embodiment of the present invention will be described.
FIG. 5 is a central sectional view of a joint part of a modification of the handrail according to the first embodiment of the present invention.
Since the joint part 4 of the modification example in the handrail 1 according to the first embodiment is substantially the same in structure as the joint part 4 in the handrail 1 according to the first embodiment described above, a modification example of the modification example of the first embodiment of the present invention is described. Only different points from the first embodiment will be described, and the same reference numerals are given to the same parts, and the description will be omitted.

In the joint portion 4 of the modified example of the handrail 1 according to the first embodiment, the first straight pipe portion 10a of the case 10 is disposed between the curved portion 10b of the case 10 and the front surface 12b of the flange cover 12. The case 10 is disposed on the front side of the front surface 12 b of the flange cover 12. The flange cover 12 forms an opening 12c in which the first core member 8 is disposed inside. The opening 12c is formed in a circular shape. The opening 12 c forms an inner diameter that is smaller than the inner diameter of the first straight pipe portion 10 a of the case 10. Therefore, the end 10 d of the case 10 is disposed so as to abut on the front surface 12 b of the flange cover 12. When the distance L1 from the wall surface W of the bar member 2 is a distance of a reference dimension defined by the flange cover 12 and the case 10, the case 10 is disposed on the front surface 12b of the flange cover 12, thereby The operator who constructs 1 can attach the bar member 2 to the position of the reference dimension relatively easily and stably.
Even when the case 10 is disposed on the front surface 12b of the flange cover 12, the length of the first straight pipe portion 10a of the case 10 is adjusted to make the case 10 relatively long. Since the length can be easily adjusted, the distance L1 from the wall surface W of the bar member 2 and the distance L5 protruding from the wall surface of the case 10 of the joint portion 4 can also be adjusted.

According to the handrail 1 according to the first embodiment of the present invention described above, the distance from the wall surface W of the bar member 2 can be adjusted by changing the length rising from the flange 6 of the first core member 8. ing. Therefore, the freedom degree which determines the above-mentioned dimension from the wall surface W of the bar member 2 can be improved.
The case 10 covers the first core member 8 and can form the appearance of the joint portion 4, and is arranged separately from the first core member 8 that requires strength. Since it is not necessary to give the case 10 strength, the thickness of the case 10 can be reduced, and the manufacturing cost of the case 10 can be reduced.

  Furthermore, according to the handrail 1 according to the first embodiment, since the second core member 14 of the joint portion 4 is fixed to the first core member 8, the bar member 2 and the joint portion are connected by the second core member 14. 4 can be reinforced, and the strength of the connection portion between the bar member 2 and the joint portion 4 can be improved.

  Furthermore, according to the handrail 1 according to the first embodiment, the second core material 14 is formed by press-fitting the second core material 14 of the joint portion 4 into the hole 8 a formed in the first core material 8. It is fixed to the first core material 8. Therefore, the second core material 14 can be firmly fixed to the first core material 8 by press-fitting, and the swinging movement between the second core material 14 and the first core material 8 can be suppressed. it can. Further, it is possible to prevent the loosening of the fastening from occurring due to the fastening with the screw.

  Furthermore, according to the handrail 1 according to the first embodiment, the opening 12a of the flange cover 12 is located between the first core member 8 and the end 10d of the case 10 that is disposed outside the first core member 8. A gap to be inserted is formed, and the amount of insertion of the end 10d of the case 10 into the opening 12a of the flange cover 12 is variably configured. Therefore, by adjusting the amount of insertion of the end portion 10d of the case 10 into the flange cover 12, it is possible to adjust the forward dimension of the case 10 from the wall surface W.

  Furthermore, according to the handrail 1 according to the first embodiment, since the first core member 8 is a hollow metal pipe, the cost can be reduced as compared with a cylindrical metal rod, By cutting the metal pipe into an arbitrary length, the length of the first core member 8 can be adjusted relatively easily.

Next, a handrail according to a second embodiment of the present invention will be described with reference to FIGS. The handrail according to the second embodiment includes a joint portion that arranges the bar member of the handrail according to the present invention so that the distance from the wall surface is relatively large. 6 is a perspective view showing a joint portion of a handrail according to the second embodiment of the present invention, and FIG. 7 is a central sectional view of the joint portion of the handrail according to the second embodiment of the present invention.
Since the handrail 101 according to the second embodiment has substantially the same structure as the handrail 1 according to the first embodiment described above, only the differences from the first embodiment of the second embodiment of the present invention will be described. About the part, the same referential mark is attached | subjected to drawing and description is abbreviate | omitted.

The handrail 101 includes a joint portion 104 that fixes the bar member 2 to the wall surface W.
The joint portion 104 includes a first core member 108 fixed to the flange 6, a case 10 that covers the first core member 108, and a flange cover 12 that covers the flange 6.

  The first core member 108 is disposed so as to rise from the flange 6 toward the bar member side. The first core member 108 extends in the vertical direction with respect to the wall surface W. The first core member 108 is a cylindrical member and is a metal pipe. The first core member 108 can be formed to an arbitrary length by cutting a long general-purpose stainless steel pipe. For this reason, the 1st core material 8 is formed very easily. The first core material 108 in the second embodiment is formed longer than the first core material 8 in the first embodiment. Therefore, for example, the distance L6 from the wall surface W of the bar member 2 can be made relatively large in a public facility or the like. The distance L6 of the handrail 1 can be adjusted by changing the length L2 rising from the flange 6 of the first core member 108. The distance L6 is a so-called forward dimension from the wall surface W of the bar member 2. Specifically, the distance L6 is a distance from the wall surface W to the axis of the bar member 2. By adjusting the length L2 of the first core member 108 to an arbitrary length, the distance L6 can be adjusted to an arbitrary length. A hole 8 a is formed in the front side portion of the first core member 108.

  The case 10 is made of resin and forms an exterior member that is disposed between the bar member 2 and the flange cover 12. The case 10 is formed on the outer side of the first core member 108 on the front end portion 108b side. The case 10 in the second embodiment has substantially the same structure and dimensions as the case 10 in the first embodiment. The case 10 is bent toward the bar member 2 on the front side of the first straight pipe portion 10a rising from the flange cover 12 along the first core member 108 and the front end portion 108b of the first core member 108. A curved portion 10b and a second straight pipe portion 10c extending toward the bar member 2. The first straight pipe portion 10a of the case 10 is formed to have a predetermined length L3. Thus, the case 10 forms the exterior member of the corner part of the joint part 4 with a predetermined dimension. When the distance L4 from the flange cover 12 to the bar member 2 is equal to or longer than the length L3, the case 10 is on the side of the tip 108b of the first core member 108 without adding an extension case 111 described later. Only a part of it. The length L2 of the first core member 108 is not less than a predetermined length such that the distance L4 is not less than the length L3. The case 10 covers the front end portion 108 b side of the first core member 108, thereby constituting the appearance of the front side of the joint portion 4.

In the joint portion 104, the portion of the first core material 108 that cannot be covered by the case 10 between the flange cover 12 and the case 10 due to the relatively long first core material 108 is formed in the case 10. An extension case 111 that covers the exposed first core member 108 between the flange cover 12 and the case 10.
The extension case 111 is made of resin and forms an exterior member disposed between the flange cover 12 and the case 10. The extension case 111 is formed on the outer side on the rear side of the first core member 108. The extension case 111 extends linearly in the direction rising from the flange cover 12 along the first core member 108. The extension case 111 is a cylindrical member and is a metal pipe. The extension case 111 can be formed to an arbitrary length by cutting a long general-purpose stainless steel pipe. For this reason, the extension case 111 is very easily formed to an arbitrary length and the length can be adjusted very easily.

  The extension case 111 has the same outer diameter as the outer diameter of the first straight pipe portion 10 a of the case 10. The extension case 111 forms an outer surface substantially flush with the first straight pipe portion 10 a of the case 10. The extension case 111 is formed of the same resin material as the case 10 and has the same appearance such as color and texture. Therefore, it becomes easy for the user who uses the handrail 1 to recognize that the case 10 is extended to the flange cover 12.

  As shown in FIG. 7, the flange cover 12 forms an opening 12a in which the first core member 108 is disposed inside. The opening 12a is formed in a circular shape. The opening 12a forms a gap between the first core member 108 and the end portion 111a of the extension case 111 disposed outside the first core member 108. The amount of insertion of the end 111a of the extension case 111 into the opening 12a is variably configured. The opening 12 a forms an inner diameter that is larger than the outer diameter of the extension case 111. By adjusting the amount of insertion of the end portion 111a of the extension case 111 into the flange cover 12, the distance L6 from the wall surface W of the bar member 2 and the distance L5 protruding from the wall surface of the case 10 of the joint portion 104 are adjusted. It can be configured to be possible.

  The second core member 14 is firmly fixed to the first core member 108 by being press-fitted into the hole 8 a formed in the first core member 108. The second core member 14 is disposed in a direction orthogonal to the first core member 108 and extends substantially parallel to the wall surface W. Since the first core material 108 is formed relatively long, the distance from the wall surface W of the second core material 14 is relatively large. For example, the distance L6 from the wall surface W of the bar member 2 in a public facility or the like. Can be made relatively large.

Next, FIG. 8 demonstrates the coupling part of a modification in the handrail by 2nd Embodiment of this invention.
FIG. 8 is a central cross-sectional view of a joint portion of a modified example in the handrail according to the second embodiment of the present invention.
Since the joint portion 104 of the modification example in the handrail 101 according to the second embodiment has substantially the same structure as the joint portion 104 in the handrail 101 according to the second embodiment described above, the second modification example of the second embodiment of the present invention is described. Only points different from the second embodiment will be described, and the same parts are denoted by the same reference numerals and description thereof will be omitted.

  In the joint portion 104 of the modified example of the handrail 101 according to the second embodiment, the extension case 111 is disposed between the case 10 and the front surface 12 b of the flange cover 12. The flange cover 12 forms an opening 12c in which the first core member 108 is disposed inside. The opening 12c is formed in a circular shape. The opening 12 c forms an inner diameter that is smaller than the inner diameter of the extension case 111. Therefore, the end 111 a of the extension case 111 is disposed so as to abut on the front surface 12 b of the flange cover 12. Even when the extension case 111 is disposed on the front surface 12b of the flange cover 12, the extension case 111 is very easily formed to an arbitrary length and the length can be adjusted very easily. Therefore, the distance L6 from the wall surface W of the bar member 2 and the distance L5 protruding from the wall surface W of the case 10 of the joint portion 104 can be easily adjusted.

  According to the handrail 101 according to the second embodiment of the present invention described above, the joint portion 104 is formed when the first core member 108 is exposed from the case 10 by forming the first core member 108 relatively long. Further, an extension case 111 that covers the exposed first core member 108 is provided. As a result, even when the first core member 108 is formed to be relatively long, the case 10 and the extension case 111 cover the first core member 108 relatively easily and complete the appearance of the joint portion 104. be able to. Therefore, the degree of freedom for determining the preceding dimension from the wall surface W of the bar member 2 can be further improved.
