Description

  The present invention relates to a handrail member used for handrails installed in indoor corridors, stairs, bathrooms, etc., or outdoor stairs, verandas, fences, railings, higashiya, and the like.

  In general, when a handrail member is gripped, in order to increase the touch feeling and ease of gripping, the covering surface layer is mixed with a small amount of titanium oxide fine powder, and the fine particle wood powder having a diameter of 10 to 100 μm is reduced to 5 to 50%. On the other hand, a covering material for handrails is disclosed which is formed by extrusion molding from a pellet compound containing wood powder whose remainder is soft or semi-rigid polyvinyl chloride containing 10 to 50% of a plasticizer, and which gives a tactile feel that is familiar to the hand. (For example, refer to Patent Document 1).

  In addition, when gripping the handrail member, in order to make it easier to grip and less slippery, a plurality of concave strips that fit the belly of the fingers when gripped by the hand on the outer surface of a rod-shaped material with a diameter that can be gripped by hand A handrail member characterized by being formed by being folded is disclosed (for example, see Patent Document 2).

  However, the handrail member has the following problems. That is, in the handrail member as described in Patent Document 1, the surface has a pleasant tactile sensation when gripped, but the covering does not deform following the finger, and is not necessarily sufficient in terms of ease of gripping. .

  Moreover, in the handrail member as described in Patent Document 2, the grip of the finger of the hand fits into the concave streak when gripped with a hand, and it is difficult to slip even if the grip force is weak. Thus, the covering was not deformed and was not always sufficient in terms of ease of gripping.

  The present invention is intended to solve the above-described problems and provide a handrail member that is easy to grip and difficult to slip when a user grips the handrail member.

In order to achieve the above object, the present invention is configured as follows.
That is, in the handrail member according to the present invention, a non-slip portion having a predetermined width is formed along a length direction of a part of the handrail body, and the non-slip portion is tube-shaped and is spaced on the outer surface in the length direction. And a plurality of protrusions are formed.

  According to the present invention, when the non-slip portion formed along the length direction is gripped, the protrusion is formed on the outer surface with a space in the length direction. Is slippery. Further, in the protruding portion and the portion other than the protruding portion, the portion other than the protruding portion can be pressed and deformed by a tube shape, and the protruding portion is suppressed from being pressed and deformed compared to the portion other than the protruding portion. By doing so, in addition to the above effects, when a force is applied to the gripped hand, the parts other than the protrusions are pressed and deformed, and the pressing deformation of the protrusions is suppressed, so that the hand is further followed. Anti-slip is made effectively.

  It is preferable that the anti-slip portion is formed on the lower surface of the handrail main body, because the finger naturally follows the handrail when it is gripped by the hand. It may be the upper surface.

  Next, the best mode for carrying out the present invention will be specifically described with reference to the drawings.

  1 is a perspective view showing another embodiment of a handrail member according to the present invention, FIG. 2 is a front view of FIG. 1, FIG. 3 is a sectional view taken along line XX of FIG. 1, and FIG. -Y sectional view, FIG. 5 is a front view of the support member, and FIG. 6 is a sectional view showing another embodiment of the non-slip portion.

  As shown in FIGS. 1 and 2, the handrail member P according to the present embodiment includes a core material 1 formed in the length direction, a covering material 2 attached to an upper portion of the core material 1, and a core material 1. It is mainly composed of a non-slip part 3 attached to the lower part.

  First, the core material 1 is a cylindrical body whose lower part is formed flat. The flat part 11 is formed along the longitudinal direction below the center of the cylinder of the core material 1, and the upper cylindrical part of the core material 1. 12 is attached with a flexible covering material 2 having a substantially uniform thickness around it. At both lower ends of the cylindrical portion 12, fitting grooves 13 are formed in the longitudinal direction toward the inner side of the core material 1, and the side end portions of the covering material 2 are folded back along the side wall surfaces of the fixing grooves 13. A fitting portion 21 is provided, and the fitting portion 21 is inserted into the fitting groove 13. With this structure, the covering material 2 is prevented from being inadvertently detached from the core material 1.

  The material for forming the core material 1 is generally composed of a member obtained by cutting a long mold material obtained by extrusion molding of aluminum or synthetic resin into an appropriate length. However, a metal other than aluminum or a metal Depending on the length of the core material 1 and the required strength, such as a composite material of bismuth and a synthetic resin, it can be used as appropriate.

  Examples of the flexible synthetic resin material for forming the covering material 2 include silicone rubber, butadiene styrene rubber, neoprene, butadiene acrylonitrile rubber, chloroprene polymer, butyl rubber, ethylene propylene terpolymer, urethane resin, polyisobutylene resin, polyethylene. Various synthetic rubbers such as resins, ethylene vinyl acetate copolymers, silicone resins, soft and hard vinyl chloride resins, styrene-butadiene, polyolefin, polyester, polyvinyl chloride, polyurethane, and polyamide elastomers An elastic material made of a resin or the like or a foamed material thereof can be used depending on the required hardness and flexibility.

  The covering material 2 may be formed only from the above-described flexible synthetic resin material. However, a flexible material is used only on the outer surface of the covering material 2, and the inner layer has a relatively high hardness or A synthetic resin having high rigidity may be used. Then, the covering material 2 is more difficult to come off from the core material 1.

  Subsequently, the anti-slip portion 3 is a flexible tube shape continuous in the length direction, the outer surface of the peripheral wall forming the anti-slip portion 3 is formed in a curved shape, and the hollow portion 31 is formed therein. In addition, two mounting ridges 32 are juxtaposed in the length direction.

  The anti-slip portion 3 is attached to the core member 1 with the engaging protrusion 32 engaged with the locking groove 14 formed in the flat portion 11 of the core member 1. When the engaging ridge 32 is provided with a flange portion 33 on the outer surface, and the recess 15 is formed in the locking groove 14 of the flat portion 11, the engaging ridge 32 is inserted into the locking groove 14. In addition, the flange 33 is locked to the recess 15. As a result, the non-slip portion 3 is not easily detached from the core material 1. In this embodiment, there are two mounting protrusions 32, but one or three or more may be used as necessary.

  When the anti-slip part 3 is attached to the core material 1, the gap between the covering material 2 and the anti-slip part 3 is eliminated, and the covering material 2 and the anti-slip part 3 come into contact with each other. A gap is formed so that the coating material and the non-slip portion do not come into contact with each other and cause unnecessary distortion, or the user's fingertips do not enter or get caught. May be.

  The antiskid part 3 is generally composed of a member obtained by cutting a long core obtained by extruding a synthetic resin into an appropriate length, but the engaging protrusion 32 and the antiskid part 3 are The anti-slip portion 1 and the engaging protrusion 32 may be bonded after molding separately.

  When attaching the antiskid part 3 to the flat part 11 of the core material 1, the antiskid part 3 may be attached from the opening direction of the locking groove 14 of the flat part 11, or the end part of the flat part 11 of the core material 1. The engaging protrusion 32 may be attached while sliding into the locking groove 14.

  The non-slip portion 3 is pressed outward by a support portion 41 provided in the hollow portion 31 at a predetermined interval, and protrusions 34 are formed on the outer surface at a predetermined interval. That is, the non-slip portion 3 can be pressed and deformed at the portion other than the projection 34 by the hollow portion 31 on the inner surface, and the portion of the projection 34 is pressed and deformed by the support portion 41 as compared with the portion other than the projection 34. Will be suppressed. Accordingly, when the user's finger is positioned so as to be positioned at the position of the non-slip portion 3 when the handrail member P is gripped, the portion without the projecting portion 34 is formed on the finger by the hollow portion 31 on the inner surface. Since it deform | transforms following, it can grasp firmly, and since the deformation | transformation of the protrusion 34 is suppressed, the slip prevention to the length direction of the handrail member P is made more effective.

  4 and 5 are hemispherical in shape and formed at predetermined intervals along the length direction on the support plate 42, and the inner surface of the non-slip portion 3 at the hemispherical top. It is made to press from. As shown in FIG. 3, the hollow portion 31 remains between the portion of the support plate 42 without the support portion 41 and the inner surface of the anti-slip portion 3. Accordingly, when the support plate 42 is inserted into the anti-slip part 3, the protrusion 34 is easily formed on the outer surface of the anti-slip part 3, and when the user grasps the handrail member P, the anti-slip part 34 is formed. The portion of the stopper 3 that does not have the protrusion 34 is pressed and deformed following the user's finger, but the support plate 42 prevents the pressing deformation more than necessary.

  The connecting plate 42 has a groove 43 formed on the bottom surface thereof. Thereby, it is possible to suppress the frictional resistance generated when the support plate 42 is inserted into the hollow portion 31 of the non-slip portion 3.

  Even after the handrail member P is installed, the support plate 42 can be replaced, and the protrusion formed on the non-slip portion 3 by changing the pitch or height of the support portions 41 provided on the support plate 42. The shape and interval of 34 can be changed. Thereby, the form of the protrusion 34 of the anti-slip | skid part 3 can be changed according to a user's favorite grip condition.

  Examples of the flexible synthetic resin material forming the non-slip portion 3 include silicone rubber, butadiene styrene rubber, neoprene, butadiene acrylonitrile rubber, chloroprene polymer, butyl rubber, ethylene propylene terpolymer, urethane resin, polyisobutylene resin, and polyethylene resin. , Ethylene vinyl acetate copolymer, silicone resin, soft and hard vinyl chloride resin, styrene-butadiene, polyolefin, polyester, polyvinyl chloride, polyurethane, polyamide, and other synthetic rubbers and resins An elastic material similar to the covering material 2 made of the above or a foamed material thereof can be used depending on the required hardness and flexibility. The anti-slip portion 3 may be made of a material having higher flexibility than the covering material 2. If it does in this way, when a user grasps handrail member P, it will be made easy to follow a finger more effectively. Further, if a material having higher rigidity than the anti-slip part 3 is used for the engaging protrusion 32 of the anti-slip part 3, it is more difficult to come off when engaged with the engaging groove 14 of the flat part 11 of the core material 1. The

  The support portion 41 is generally formed by pressing a support plate 42 obtained by extruding aluminum into a suitable length by pressing a support plate 42 obtained by pressing aluminum. Other than those using a metal such as a steel material or a stainless alloy, or using a synthetic resin as a raw material, a support plate 42 having a support portion 41 formed by extrusion molding, a support portion 41 and a support plate 42 They can be used appropriately according to the required length and strength, such as those formed separately and connected later.

  Further, the support portion 41 may be formed on the anti-slip portion 3. Specifically, the protrusion 34 is formed in advance on the outer surface of the anti-slip portion 3, and the support portion 41 is formed on the inner wall surface of the hollow portion 31 located on the inner surface thereof. At this time, the support portion 41 may be configured to project from the inner wall surface on the outer surface side, or may be configured to project from the inner wall surface on the core material side. Moreover, the front-end | tip of the support part 41 may be connected with the inner wall surface which opposes, and may have a predetermined space | interval.

  The non-slip portion 3 according to the present embodiment is formed in a tube shape by a peripheral wall without a notch, and is a form in which a support plate 42 is inserted from an opening at an end thereof. The non-slip portion 3 is formed by forming a notch 35 in the length direction in a part of the peripheral wall, and by doing so, the support plate 42 can be inserted from the notch 35, Is made easier. The same effect can be obtained even if a slit (not shown) is formed in the length direction instead of the notch 35.
