Hereinafter, a handrail structure according to a first embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 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 the handrail according to the first embodiment of the present invention, and FIG. 3 is a handrail according to the first embodiment of the present invention. It is the elements on larger scale which expanded the part fixed to the wall surface. In FIG. 3, the screw 12 is omitted.

  As shown in FIGS. 1 to 3, the handrail 1 is a handrail fixed to the wall surface W, and in particular, is a handrail provided in a water environment such as a toilet, a washstand, and a bathroom. The handrail 1 can be provided in public facilities or home buildings that require countermeasures against infectious diseases such as stations, hospitals, and elderly facilities.

The handrail 1 includes a handrail main body portion 2 extending from the wall surface W to the wall surface W, a metal flange portion 4 connected to the end portion 2 a of the handrail main body portion 2 and fixed to the wall surface W, and the flange portion 4. A flange cover 6 for covering is provided.
The handrail body 2 side when viewed from the flange portion 4 of the handrail 1 is the front side, the wall surface W side when viewed from the flange portion 4 is the rear side, the center side of the flange portion 4 is the inside, and the center side of the flange portion 4 is On the other hand, the opposite side in the radial direction is described as the outside.

  The handrail main body 2 includes a bar member 8 that forms a grip portion of the user on the front side of the wall surface W, and a covering portion 10 that covers the bar member 8 with a resin material.

  The bar member 8 includes a straight portion 8a extending along the wall surface W and a joint portion 8b connected to the straight portion 8a and supporting the straight portion 8a. An end portion on the wall surface W side of the bar member 8 forms an end portion 2 a of the handrail main body portion 2. The bar member 8 is a cylindrical member and is a metal pipe, for example, a stainless steel pipe. The bar member 8 is formed by bending a metal pipe, and has strength to withstand the load of the user and resistance to repeated use. Since the bar member 8 is made of stainless steel, it has relatively strong corrosion resistance against, for example, water, a disinfecting ethanol solution, and an isopropanol solution.

  The covering portion 10 covers the bar member 8 with a resin material. The covering portion 10 covers a portion of the bar member 8 that extends forward from the flange cover 6 to form an exterior portion. The covering portion 10 can protect the bar member 8 and improve the corrosion resistance of the bar member 8.

  The flange portion 4 is a member that spreads in a collar shape. The flange portion 4 includes a plate portion 4a that is formed in an annular shape and formed in a flat plate shape. The plate portion 4a is formed with an inner peripheral opening portion 4b inside the plate portion 4a. The plate portion 4a is further formed with a hole 4c through which a screw 12 for fixing the flange portion 4 to the wall surface W is inserted. The plate portion 4a is fixed in a state where the plate 12a is disposed in a direction along the wall surface W by inserting the screw 12 into the hole 4c. The flange portion 4 is a thin plate member made of metal, for example, stainless steel. Since the flange portion 4 is made of stainless steel, it has a relatively strong corrosion resistance against, for example, water, a disinfecting ethanol solution, and an isopropanol solution.

  The flange cover 6 is formed in a cylindrical cap shape. The flange cover 6 forms a cover that covers the front side of the flange portion 4 and the outside in the radial direction (peripheral direction). The flange cover 6 forms an opening 6h in which the handrail main body 2 is disposed inside. The opening 6h is formed in a circular shape. A slight gap C is formed between the opening 6 h of the flange cover 6 and the covering portion 10 of the handrail main body 2. The flange cover 6 is made of a resin material.

Next, the handrail plate according to the first embodiment of the present invention will be described with reference to FIGS.
4 is a front view of the handrail according to the first embodiment of the present invention as viewed from the wall surface side, and FIG. 5 is a perspective view of the handrail plate according to the first embodiment of the present invention as viewed obliquely from the front side. FIG. 6 is a perspective view of the handrail plate according to the first embodiment of the present invention as viewed obliquely from the rear side.

The handrail 1 further includes a plate 14 that is a first liquid guiding portion that guides the chemical solution so as to suppress the adhesion of the chemical solution to the flange portion 4. The plate 14 is provided in a direction along the wall surface W between the wall surface W and the flange portion 4. The plate 14 is formed in an annular shape and is formed in a flat plate shape. The plate 14 has a discharge groove 14b, which is a discharge groove for discharging the chemical solution, formed on the rear surface 14a of the wall surface portion. The plate 14 forms a discharge groove 14b by a concave groove or a convex rib.
The chemical solution is a solution containing hypochlorous acid, such as a sodium hypochlorite solution, hypochlorous acid water, and other chlorine-based disinfectants containing hypochlorous acid. Such a chemical solution is used as a powerful disinfectant applicable to a larger number of infectious pathogens than an ethanol solution as a countermeasure against infectious diseases. In the first embodiment of the present invention, the induction of a chemical solution is exemplified, but it may be applied to a liquid other than the chemical solution, for example, water or salt water.

  The discharge groove 14b of the plate 14 is formed so that most of the discharge groove 14b is a downward-facing flow path so that the chemical liquid is less likely to stay in the discharge groove 14b in a state where the plate 14 is attached to the wall surface W. ing. The discharge groove 14b is preferably formed such that a portion of three or more quarters of the discharge groove 14b, more preferably substantially all of the discharge groove 14b is a downward-facing flow path. Regardless of the direction (up / down, left / right, angle) of the plate 14 with the plate 14 attached to the wall surface W, the lower surface of each portion of the discharge groove 14b is inclined downward from the horizontal. Further, the discharge groove 14b is formed so as not to form a trap portion that is folded back from the downstream channel to the upstream channel. Therefore, the discharge groove 14b is formed in a structure that makes it difficult to keep the chemical in the discharge groove 14b, and the chemical is easily discharged from the discharge groove 14b to the outside of the plate 14. The discharge groove 14b has a flow path diameter that allows the chemical solution to move along the discharge groove 14b by surface tension in the entire flow path with the plate 14 attached to the wall surface W. Therefore, the chemical | medical solution which flowed into the discharge groove 14b flows below along the discharge groove 14b, and flows out downward from any opening part 14e. The opening portion 14e is formed so that the discharge groove 14b is slightly expanded while forming a flow path through which the chemical solution can be transferred by surface tension. The opening portion 14e functions as an inlet portion for the chemical liquid depending on the mounting direction of the plate 14.

  Further, the plate 14 forms an outer peripheral discharge groove 14c, which is a discharge groove for discharging the chemical solution, in the outer peripheral portion 14d of the wall surface side portion. The outer peripheral discharge groove 14c of the plate 14 is formed as a slight gap outside the outer peripheral portion 14d. The outer peripheral discharge groove 14 c is formed between the outer peripheral portion 14 d and the flange cover 6. The outer peripheral discharge groove 14 c forms an annular flow path along the outer periphery of the plate 14. The outer peripheral discharge groove 14c has a flow path diameter that allows the chemical solution to move along the outer peripheral discharge groove 14c by surface tension in the entire flow path with the plate 14 attached to the wall surface W. Therefore, the chemical liquid flowing into the outer peripheral discharge groove 14c from between the flange cover 6 and the wall surface W or the chemical liquid flowing into the outer peripheral discharge groove 14c through the opening portion 14e of the discharge groove 14b is lowered along the outer peripheral discharge groove 14c. Flow down to the side. A groove portion 14 f to be attached to the flange cover 6 is formed on the outer peripheral portion 14 d of the plate 14. An outer peripheral portion 14d of the plate 14 is in contact with an inner peripheral portion of the flange cover 6, for example, an engaging portion 6g described later. When the chemical liquid flows between the wall surface W and the flange cover 6, the chemical liquid flows from the engaging portion 6 g of the flange cover 6 to the outer peripheral portion 14 d of the plate and flows into the discharge groove 14 b and the outer peripheral discharge groove 14 c of the plate 14. It is easy to flow along.

  The plate 14 is attached so that the top portion 14j of the plate 14 and the top portion 6j of the flange cover 6 are in contact with each other. Since the top portion 14j of the plate 14 and the top portion 6j of the flange cover 6 are in contact with each other, when the chemical solution flows between the wall surface W and the top portion 6j of the flange cover 6, the chemical solution is transferred from the top portion 6j of the flange cover 6 to the plate. 14 is transmitted to the top 14j of the plate 14, and can easily flow along the discharge grooves 14b and the outer periphery discharge grooves 14c of the plate 14.

  The plate 14 has a hooking portion 14 g on which the flange portion 4 can be disposed on the front side of the plate 14. The hook portion 14 g extends from the front surface 14 h of the plate 14 to the front side, and the flange portion 4 is disposed on the front side of the plate 14. Therefore, the flange portion 4 can be arranged away from the wall surface W and parallel to the wall surface W. Further, the hooking portion 14 g can be arranged such that the flange portion 4 is spaced above the first wall portion 6 a below the flange cover 6. Therefore, it is possible to prevent the chemical liquid flowing on the lower first wall portion 6 a from adhering to the flange portion 4.

Next, the handrail flange cover according to the first embodiment of the present invention will be described with reference to FIGS.
FIG. 7 is a perspective view of the flange cover of the handrail according to the first embodiment of the present invention when viewed obliquely from the rear side.

The flange cover 6 covers the end portion on the wall surface W side of the bar member 8 of the handrail main body portion 2 together with the flange portion 4.
The flange cover 6 has a first wall portion 6a that is a second liquid guide portion extending forward from the wall surface W on the outer side in the radial direction of the flange portion 4, and a front portion 6b of the first wall portion 6a toward the handrail main body portion 2. A second wall 6c that is a second liquid guiding portion that extends in the longitudinal direction and a flap portion 6d that is a second liquid guiding portion that extends rearward and slightly inward from the inner end of the second wall 6c. I have. As described above, the flange cover 6 forms the second liquid guiding portion inside itself by at least the first wall portion 6a and the second wall portion 6c.

The first wall portion 6a is formed in a cylindrical shape whose rear side slightly expands. The first wall portion 6a forms an inner side surface 6e of the first wall portion 6a formed as a downward slope toward the wall surface W side below the central axis A passing through the center of the flange cover 6. The inner side surface 6e forms a downward slope that descends from the front toward the rear at the lower portion of the flange cover 6. The second liquid guiding portion is formed by the inner side surface 6e of the first wall portion 6a.
An engaging portion 6g that engages with the groove portion 14f of the plate 14 is formed on the first wall portion 6a at the downstream end, that is, the rear end portion of the first wall portion 6a. An engaging portion 6g is formed in the first wall portion 6a, but the chemical solution is formed so as to be discharged from the downstream end to the outside of the flange cover 6 along the inner surface 6e of the first wall portion 6a. ing. The engaging portion 6g is formed on the whole or a part of the inner periphery of the flange cover 6.

  The 2nd wall part 6c is formed in the annular | circular shape that a back side spreads comparatively large. The second wall portion 6c forms an inner side surface 6f of the second wall portion 6c formed as a downward slope toward the wall surface W side below the central axis A passing through the center of the flange cover 6. The inner side surface 6 f forms a downward slope that descends from the front to the rear on the lower side of the center axis A of the flange cover 6.

  The flap portion 6d is formed in a cylindrical shape whose rear side is reduced in diameter. The flap portion 6 d is formed so that the tip on the rear side thereof is in contact with the covering portion 10 of the handrail main body portion 2 or approaches the covering portion 10 to the extent that water drops do not easily pass along the covering portion 10. Therefore, the chemical solution flowing in along the covering portion 10 contacts the flap portion 6d and flows down along the flap portion 6d. A slit hole 6i through which a chemical can pass is formed at the lower part of the flap portion 6d. Therefore, the chemical solution flowing down along the flap portion 6d can flow down along the inner side surface 6f inside the flange cover 6 from the slit hole 6i.

Next, the operation of the handrail according to the first embodiment of the present invention will be described with reference to FIGS. 2, 3, 4 and 7.
When the user disinfects the handrail 1 using a chemical solution as a countermeasure against infectious diseases, the user sprays the chemical solution on the handrail 1 using a spray or the like or attaches the chemical solution to a cloth or the like on the handrail 1 Disinfection is performed by painting or applying chemicals to the handrail 1 by other methods. At this time, the chemical liquid may flow into the flange cover 6 from the gap between the wall surface W and the flange cover 6 as indicated by an arrow F1 in FIG. In addition, the chemical liquid may flow into the flange cover 6 from the gap between the handrail main body 2 and the flange cover 6 as indicated by an arrow F20.

  With reference to FIG.3 and FIG.5, the case where a chemical | medical solution flows in into the flange cover 6 from the clearance gap between the wall surface W and the flange cover 6 as shown by arrow F1 is demonstrated. The chemical solution flowing in from the top portion 6j of the flange cover 6 flows down along the top portion 14j of the plate 14 and flows along the discharge groove 14b or the outer periphery discharge groove 14c. The chemical liquid flowing in the outer peripheral discharge groove 14c flows down to the lower side of the plate 14 along the outer peripheral discharge groove 14c as indicated by an arrow F10.

The chemical solution flowing into the discharge groove 14b flows down the discharge groove 14b due to surface tension. For example, as shown by arrows F2 to F4, the chemical liquid flows downward along the discharge groove 14b. Since most of the discharge groove 14b is formed to be a downward flow path, the chemical liquid is unlikely to stay in the middle of the discharge groove 14b, and is easy to flow downward along the discharge groove 14b. .
The discharge groove 14b is formed so that most of the chemical is a downward flow path even if the chemical solution passes through the route shown by arrows F5 to F7 or the route shown by arrow F8. Therefore, it is difficult for the chemical liquid to stay in the middle of the discharge groove 14b and to flow down downward along the discharge groove 14b.
The chemical solution flows out from the opening portion 14e of the discharge groove 14b into the outer peripheral discharge groove 14c.
The chemical solution that has reached the lower portion of the plate 14 is discharged out of the flange cover 6 through a gap between the wall surface W and the flange cover 6 as indicated by an arrow F9.

  In this way, the chemical solution is guided to pass through the assumed flow path on the wall surface W side of the plate 14. Therefore, it is hard for a chemical | medical solution to reach | attain to the flange part 4 side of the other side on both sides of the plate 14, and it can suppress that a chemical | medical solution adheres to the flange part 4 made from metal.

  Next, with reference to FIG. 3 and FIG. 7, the case where a chemical | medical solution flows in into the flange cover 6 from the clearance gap between the handrail main-body part 2 and the flange cover 6 as shown by arrow F20 is demonstrated. As indicated by an arrow F20, the chemical liquid flowing into the flange cover 6 along the covering portion 10 contacts the flap portion 6d, and flows down the outer periphery of the covering portion 10 along the flap portion 6d. As shown by the arrow F21, the chemical solution that has flowed down flows along the inner surface 6f of the flange cover 6 from the slit hole 6i below the flap portion 6d. As shown by the arrow F22, the inner side surface 6f is formed as a downward slope toward the wall surface W, so that the chemical liquid is likely to flow down toward the wall surface W. Further, the inner side surface 6e extending from the lower end of the inner side surface 6f is also formed as a downward slope toward the wall surface W side, so that the chemical liquid is likely to flow down toward the wall surface W side as indicated by an arrow F23. In this way, a continuous downstream channel is formed inside the flange cover 6. The chemical liquid flows down to the downstream end along the inner surface 6e. The chemical solution that has reached the lower portion of the plate 14 is discharged out of the flange cover 6 through a gap between the wall surface W and the flange cover 6 as indicated by an arrow F9.

  Thus, the chemical solution is guided to pass through the assumed flow path along the inner side surface 6f and the inner side surface 6e in the flange cover 6. Therefore, it is difficult for the chemical liquid to reach the flange portion 4 side disposed at a position separated from the inner side surface 6f and the inner side surface 6e, and it is possible to suppress the chemical solution from adhering to the metal flange portion 4.

  In addition, this embodiment suppresses that a chemical | medical solution adheres to the flange part 4. FIG. This embodiment can also suppress that water, the ethanol solution for disinfection, an isopropanol solution, seawater, etc. adhere to the flange part 4. FIG. By suppressing these water and the like from adhering to the flange portion 4, it is possible to suppress the metal flange portion from being corroded by water or the like.

Next, the effect by the handrail 1 by 1st Embodiment mentioned above is demonstrated.
According to the handrail 1 according to the first embodiment, the plate 14 is provided between the wall surface W and the flange portion 4 and guides the liquid so that the liquid adheres to the flange portion 4. Thereby, when the liquid is applied to the handrail 1, it is possible to prevent the liquid flowing between the wall surface W and the flange portion 4 from adhering to the metal flange portion 4. Therefore, it can suppress that the metal flange part 4 corrodes with a liquid.
Further, for example, when the handrail 1 is sterilized with a chemical solution, the chemical solution flowing between the wall surface W and the flange portion 4 can be prevented from adhering to the metal flange portion 4. Therefore, it can suppress that the metal flange part 4 corrodes with a chemical | medical solution.

Moreover, according to the handrail 1 according to the first embodiment, the plate 14 is a plate in which the discharge groove 14b and / or the outer periphery discharge groove 14c for discharging the liquid are formed in the wall surface W side portion. When the liquid is applied to the handrail 1 by the plate 14, the liquid flowing between the wall surface W and the flange portion 4 is discharged along the discharge groove 14 b and / or the outer peripheral discharge groove 14 c to the metal flange portion 4. It can suppress that it adheres more. Therefore, it can suppress more that the metal flange part 4 corrodes with a liquid.
