Description

The disclosed embodiments relate to handrail materials and handrails.

In general houses and public facilities, handrails may be installed to assist movements such as walking and leaning. For example, in the case of a general house, handrails are attached to the walls of toilets, bathrooms, stairs, corridors, entrances, and the like.

Such a handrail may be provided with irregularities along the longitudinal direction in order to suppress slippage during use.

For example, in Patent Document 1, thick-walled protrusions and thin-walled protrusions are alternately arranged along the longitudinal direction of the hollow member with respect to the outer peripheral surface of the cylindrical hollow member, and these hollow members and thick-walled protrusions are provided. A handrail in which a portion and a thin-walled protruding portion are coated with a coating layer is described. According to such a handrail, it is possible to suppress slippage in the longitudinal direction.

Japanese Patent No. 2896756

However, the above-mentioned prior art has not considered suppressing slippage of the handrail in the circumferential direction.

One aspect of the embodiment is to provide a handrail material and a handrail capable of suppressing slippage in the circumferential direction.

The handrail material according to one aspect of the embodiment includes a cylindrical or columnar core material and a plurality of handrail materials arranged side by side with respect to the outer peripheral surface of the core material at intervals along the longitudinal direction of the core material. A convex piece and a covering material for covering the core material together with the plurality of convex pieces are provided, and the convex piece is a covering material in a side view of the convex piece along the longitudinal direction of the core material. The contour of the contact surface is continuous with each of the two side portions formed in a shape along a virtual arc having a predetermined curvature and the two side portions at both ends, and in the side view, the covering material. The contour of the contact surface with the above is characterized by having an upper portion formed in a shape other than the shape along the virtual arc.

When the user grips the handrail material and applies a force in the circumferential direction, the user's hand can be caught at the boundary portion between the two side portions and the upper portion. Therefore, for example, as compared with the case where a convex piece in which both side portions and the upper portion are smoothly continuous in an arc shape is used, it is possible to suppress slippage of the core material in the circumferential direction.

Further, the upper portion of the convex piece is characterized in that the contour of the contact surface with the covering material is formed in a straight line in the side view.

As a method of suppressing slippage of the core material in the circumferential direction, it is conceivable to increase the thickness of the convex piece, in other words, to increase the height of protrusion of the core material from the outer peripheral surface. However, as the thickness of the convex piece increases, in other words, the height of protrusion from the outer peripheral surface of the core material increases, when the user grips the handrail material, the convex portion having an uneven shape becomes the user's finger or palm. There is a risk of causing pain to the user by biting into the meat or hitting the joints. On the other hand, in the handrail material according to one aspect of the embodiment, by making the upper part of the convex piece a flat surface, it is possible to suppress the sliding of the core material in the circumferential direction while suppressing the protruding height of the convex piece. .. Therefore, it is possible to provide a handrail material that is less likely to cause pain to the user and is less likely to slip in the circumferential direction of the core material.

Further, the upper portion of the convex piece is characterized in that the contour of the contact surface with the covering material is formed in a concave shape recessed toward the core material in the side view.

By denting the upper part of the convex piece, it is possible to suppress the sliding of the core material in the circumferential direction while suppressing the protruding height of the convex piece. Therefore, it is possible to provide a handrail material that is less likely to cause pain to the user and is less likely to slip in the circumferential direction of the core material. Further, the meat of the user's hand gets into the recessed portion, so that the user's hand can be more strongly caught. Therefore, slippage of the core material in the circumferential direction can be further suppressed.

Further, the upper portion of the convex piece is formed in a convex shape in which the contour of the contact surface with the covering material protrudes toward the covering material side from the virtual arc having the predetermined curvature in the side view. It is a feature.

By positively providing the protrusion on the upper part of the convex piece, it is easy for the user to get caught by the hand. In other words, even when the user grips the handrail material with a relatively weak force, the user's hand can be caught. Therefore, it is possible to more reliably suppress slippage in the circumferential direction.

Further, the handrail according to one aspect of the embodiment is characterized by including any one of the above-mentioned handrail materials and a support member fixed to the installation surface and supporting the handrail material.

This makes it possible to provide a handrail capable of suppressing slippage of the core material in the circumferential direction.

According to one aspect of the embodiment, slippage in the circumferential direction can be suppressed.

(First Embodiment)
<Overall composition of handrails>
First, the overall configuration of the handrail according to the first embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is an external perspective view of the handrail according to the first embodiment, and FIG. 2 is a side view of the handrail according to the first embodiment. In the following, in order to clarify the positional relationship, the X-axis, Y-axis, and Z-axis that are orthogonal to each other are defined, and the positive direction of the Z-axis is defined as the vertically upward direction.

As shown in FIG. 1, the handrail 100 according to the first embodiment is arranged in the toilet room R. The handrail 100 is attached to the wall surface W located on the side of the toilet bowl U.

The handrail 100 is mounted vertically with respect to the wall surface W, but the mounting direction of the handrail 100 is not limited to the vertical orientation. For example, when the handrail 100 is installed in the corridor, the handrail 100 may be mounted sideways with respect to the wall surface of the corridor.

As shown in FIG. 2, the handrail 100 includes a handrail material 1 and two support portions 2. The handrail material 1 is a rod-shaped member gripped by the user. The two support portions 2 are members for fixing the handrail material 1 to the wall surface W, and are attached to both ends of the handrail material 1.

The two support portions 2 are screwed to the wall surface W, for example. As a result, the handrail material 1 is supported by the two support portions 2 in a state of being separated from the wall surface W.

The installation surface of the handrail 100 is not limited to the wall surface. For example, the handrail 100 is a floor support type handrail in which the handrail material 1 is supported by a plurality of support portions 2 (so-called balusters) fixed to the floor surface (for example, the tread surface of stairs) and extending upward. May be good.

As shown in FIG. 2, the handrail material 1 is provided with an uneven shape along the longitudinal direction of the handrail material 1. As a result, slippage of the handrail material 1 in the longitudinal direction can be suppressed. From the viewpoint of design, the uneven shape of the handrail material 1 is provided on the wall surface W side.

The handrail material 1 according to the first embodiment can suppress not only slipping in the longitudinal direction but also slipping in the circumferential direction of the handrail material 1 by devising the uneven shape. Hereinafter, a specific configuration of the handrail material 1 according to the first embodiment will be described.

<Overall composition of handrail material>
FIG. 3 is a cross-sectional view taken along the line AA of FIG. Further, FIG. 4 is an external perspective view of the core material and the plurality of convex pieces.

As shown in FIGS. 3 and 4, the handrail material 1 includes a core material 10, a plurality of convex pieces 20, and a covering material 30.

The core material 10 is a cylindrical member, and is formed of, for example, metal or resin. The core material 10 is not limited to a cylindrical shape, but may be a cylindrical shape.

The core material 10 extends in a direction orthogonal to the circumferential direction, here in the Z-axis direction. That is, the core material 10 has the Z-axis direction as the longitudinal direction (see FIG. 4). The outline of the cross section perpendicular to the longitudinal direction is circular, specifically, a perfect circle (see FIG. 3).

The plurality of convex pieces 20 are arranged side by side with respect to the outer peripheral surface of the core material 10 at intervals from each other along the Z-axis direction which is the longitudinal direction of the core material 10. Each convex piece 20 is made of, for example, resin.

The covering material 30 is a member that covers the core material 10 together with the plurality of convex pieces 20. The covering material 30 is made of, for example, a resin.

The handrail material 1 configured as described above is, for example, in a state where a plurality of convex pieces 20 are arranged side by side at intervals along the longitudinal direction of the core material 10 on the outer peripheral surface of the core material 10. And a plurality of convex pieces 20 are formed by coating with a covering material 30 by extrusion molding. By interposing a plurality of convex pieces 20 between the core material 10 and the covering material 30, an uneven shape is formed on the outer surface of the covering material 30, that is, the outer surface of the handrail material 1.

<Composition of convex pieces>
Next, the configuration of the convex piece 20 will be specifically described with reference to FIGS. 5 to 8. 5 and 7 are side views of the convex piece 20 according to the first embodiment as viewed along the longitudinal direction of the core material 10, and FIG. 8 is a plan view of the convex piece 20 according to the first embodiment. It is a figure. In FIG. 6, the contact surface 211 of the two side portions 21 of the convex piece 20 with the covering material 30 is shown by a solid line, and the other parts of the convex piece 20 are shown by a broken line. Further, in FIGS. 7 and 8, the contact surface 221 of the upper portion 22 of the convex piece 20 with the covering material 30 is shown by a solid line, and the other portion of the convex piece 20 is shown by a broken line.

As shown in FIG. 5, the convex piece 20 is an arch-shaped member curved along the circumferential direction of the core material 10, and has a predetermined thickness outward in the radial direction of the core material 10. The convex piece 20 includes two side portions 21 and an upper portion 22 continuous with each of the two side portions 21 at both ends.

As shown in FIG. 6, the two side portions 21 of the convex piece 20 are formed so that the contour of the contact surface 211 with the covering material 30 is formed along a virtual arc V1 having a predetermined curvature in a side view. ..

On the other hand, in the upper portion 22 of the convex piece 20, the contour of the contact surface 221 with the covering material 30 is formed in a shape other than the shape along the virtual arc V1 in the side view.

Specifically, as shown in FIGS. 7 and 8, the upper portion 22 of the convex piece 20 has a flat surface 221a and two inclined surfaces 221b. The flat surface 221a is a surface perpendicular to the thickness direction (Y-axis direction) of the convex piece 20 in a side view. In other words, the flat surface 221a is a surface perpendicular to the straight line L connecting the center P of the core member 10 and the center of the convex piece 20 in the side view. Further, the flat surface 221a is a surface parallel to the wall surface W when the handrail 100 is attached to the wall surface W. As shown in FIG. 7, the flat surface 221a has a linear shape in a side view.

The two inclined surfaces 221b are surfaces that are connected to the flat surface 221a and the contact surface 211 of the side portion 21 with the covering material 30. Here, it is assumed that the two inclined surfaces 221b are also flat surfaces, but the two inclined surfaces 221b may be formed in a curved surface shape.

As described above, the handrail material 1 according to the first embodiment includes a core material 10, a plurality of convex pieces 20, and a covering material 30. The core material 10 has a cylindrical shape or a columnar shape. The plurality of convex pieces 20 are arranged side by side with respect to the outer peripheral surface of the core material 10 at intervals along the longitudinal direction of the core material 10. The covering material 30 covers the core material 10 together with the plurality of convex pieces 20. Further, the convex piece 20 has a shape in which the contour of the contact surface 211 with the covering material 30 is along a virtual arc V1 having a predetermined curvature when the convex piece 20 is viewed along the longitudinal direction of the core material 10. The contour of the contact surface 221 with the covering material 30 is continuous with each of the two side portions 21 formed in the above and the two side portions 21 at both ends, except for the shape along the virtual arc V1. It has an upper portion 22 formed in a shape.

In this way, by making the shape of the upper portion 22 of the convex piece 20 a shape other than the shape along the virtual arc V1, when the user grips the handrail material 1 and applies a force in the circumferential direction, 2 At the boundary between the side portion 21 and the upper portion 22, the user's hand can be caught. Therefore, as compared with the case where the convex pieces in which both side portions and the upper portion are smoothly continuous in an arc shape are used, slippage of the core material 10 in the circumferential direction can be suppressed.

Further, in the handrail material 1 according to the first embodiment, the upper portion 22 of the convex piece 20 has a linear contour of the contact surface 221 with the covering material 30 in a side view. That is, the upper portion 22 of the convex piece 20 has a flat surface 221a.

As a method of suppressing slippage of the core material in the circumferential direction, it is conceivable to increase the thickness of the convex piece, in other words, to increase the height of protrusion of the core material from the outer peripheral surface. However, as the thickness of the convex piece increases, in other words, the height of protrusion from the outer peripheral surface of the core material increases, when the user grips the handrail material, the convex portion having an uneven shape becomes the user's finger or palm. There is a risk of causing pain to the user by biting into the meat or hitting the joints.

On the other hand, in the handrail material 1 according to the first embodiment, the upper portion 22 of the convex piece 20 is a flat surface 221a, so that the protruding height of the convex piece 20 is suppressed and the core material 10 slides in the circumferential direction. Can be suppressed. Therefore, it is possible to provide the handrail material 1 which is less likely to cause pain to the user and is less likely to slip in the circumferential direction of the core material 10. By reducing the pain when gripping, the user can grip the handrail material 1 with more force. As a result, the sliding of the core material 10 in the circumferential direction is further suppressed.

Here, an example in which only one flat surface 221a is formed on the convex piece 20 has been described, but a plurality of flat surfaces 221a are formed on the convex piece 20 along the circumferential direction of the core material 10. You may.

(Second Embodiment)
Next, the configuration of the convex piece according to the second embodiment will be described with reference to FIGS. 9 and 10. FIG. 9 is a side view of the convex piece according to the second embodiment as viewed along the longitudinal direction of the core member 10. Further, FIG. 10 is a plan view of the convex piece according to the second embodiment.

As shown in FIGS. 9 and 10, the upper portion 22A of the convex piece 20A according to the second embodiment has a concave shape in which the contour of the contact surface 221A with the covering material 30 is recessed toward the core material 10 in a side view. Is formed in.

Specifically, the upper portion 22A of the convex piece 20A has a concave surface 221Aa and two ascending inclined surfaces 221Ab. As shown in FIG. 9, the concave surface 221Aa corresponds to a surface perpendicular to the straight line L connecting the center P of the core material 10 and the center of the convex piece 20A (corresponding to the flat surface 221a in the first embodiment) in the side view. ) Is recessed toward the center P of the core material 10.

More specifically, the concave surface 221Aa has a bottom surface portion 221Aaa extending along the longitudinal direction of the core material 10 and a bottom surface portion 221Aaa from one end side and the other end side in the circumferential direction toward the bottom surface portion 221Aaa, respectively. It has two downhill inclined surfaces 221Aab that are downhill.

The two uphill inclined surfaces 221Ab are surfaces that are connected to the downhill inclined surface 221Aab on the concave surface 221Aa and the contact surface 211 on the side portion 21 with the covering material 30, and are uphill inclined from the contact surface 211 toward the downhill inclined surface 221Aab. do.

As described above, in the upper portion 22A of the convex piece 20A according to the second embodiment, the contour of the contact surface 221A with the covering material 30 is formed in a concave shape recessed toward the core material 10 side in a side view. In addition, each portion of the contact surface 221A may be formed so as to be continuous with a smooth curve in a side view.

By denting the upper portion 22A of the convex piece 20A in this way, as in the case of the convex piece 20 according to the first embodiment, the protrusion height of the convex piece 20A is suppressed and the slip of the core material 10 in the circumferential direction is suppressed. can do. Therefore, it is possible to provide the handrail material 1 which is less likely to cause pain to the user and is less likely to slip in the circumferential direction of the core material 10. Further, as compared with the case where the flat surface 221a is provided on the upper portion 22 as in the convex piece 20 according to the first embodiment, the flesh of the user's hand enters the recessed portion (concave surface 221Aa). It is possible to cause a stronger catch by the user's hand. Therefore, slippage of the core material 10 in the circumferential direction can be further suppressed.

Here, an example in which only one concave surface 221Aa is formed on the convex piece 20A has been described, but even if a plurality of concave surfaces 221Aa are formed on the convex piece 20A along the circumferential direction of the core material 10. good.

(Third Embodiment)
Next, the configuration of the convex piece according to the third embodiment will be described with reference to FIGS. 11 and 12. FIG. 11 is a side view of the convex piece according to the third embodiment as viewed along the longitudinal direction of the core member 10. Further, FIG. 12 is a plan view of the convex piece according to the third embodiment.

As shown in FIGS. 11 and 12, the upper portion 22B of the convex piece 20B according to the third embodiment has the contour of the contact surface 221B with the covering material 30 along the virtual arc V2 in the side view. It is formed in a convex shape protruding toward the side, that is, the wall surface W side. The virtual arc V2 has a curvature different from the curvature of the virtual arc V1. Specifically, the virtual arc V2 has a curvature larger than the curvature of the virtual arc V1. Therefore, the contact surface 221B projects toward the covering material 30 side, in other words, the wall surface W side, with respect to the virtual arc V1 in the side view.

As described above, in the third embodiment, the shape of the upper portion 22B of the convex piece 20B is a convex shape protruding toward the covering material 30 side. By positively providing the protrusions in this way, the user's hand is more likely to be caught as compared with the convex pieces 20 and 20A according to the first embodiment and the second embodiment described above. In other words, even when the user grips the handrail material 1 with a relatively weak force, the user's hand can be caught. Therefore, it is possible to more reliably suppress slippage in the circumferential direction.

Here, an example in which only one convex contact surface 221B is formed on the convex piece 20B has been described, but the contact surface 221B is provided along the circumferential direction of the core material 10 with respect to the convex piece 20B. A plurality may be formed.

Further, here, an example in which the upper portion 22B of the convex piece 20B is formed along the virtual arc V2 has been described, but the upper portion 22B of the convex piece 20B is at least closer to the covering material 30 side than the virtual arc V1, that is, the wall surface W. It suffices as long as it protrudes to the side, and it does not necessarily have to be formed along the virtual arc V2.

Further effects and variations can be easily derived by those skilled in the art. For this reason, the broader aspects of the invention are not limited to the particular details and representative embodiments expressed and described above. Therefore, various modifications can be made without departing from the spirit or scope of the general concept of the invention as defined by the appended claims and their equivalents.
