1. 1. Handrail member according to the present embodiment As shown in FIG. 1, the handrail member 10 according to the present embodiment includes a rod-shaped main body portion 11 extending in one direction (direction X in the drawing). The rod-shaped main body 11 is preferably made of a wood material, for example, laminated wood or solid wood of natural wood. Further, the rod-shaped main body portion 11, the contour shape of the cross section perpendicular to the axial direction A ₀ in its length direction may be between approximately constant. The rod-shaped main body portion 11 has connecting surface portions 12a and 13a at both end portions 12 and 13. However, the rod-shaped main body portion 11 may have a connecting surface portion 13a at at least one end portion 13 thereof. The length of the rod-shaped main body 11 can be changed according to conditions such as the length and position of the wall surface to be installed. A typical length is 50-5000 mm. In addition, the length can be adjusted to an appropriate length by cutting at a factory or a construction site.

One connection surface 13a is an inclined surface portion having a normal A ₁ which is inclined with respect to the axial direction A ₀ of the rod-shaped main body portion 11. Other connecting face 12a is perpendicular surface portion constituted by a plane perpendicular to the axial direction A _0. The other connecting surface portion 12a may be an inclined surface portion similar to the connecting surface portion 13a, but from the viewpoint of reducing the manufacturing cost by standardizing the parts and from the viewpoint of designability, as shown in the example of the figure, the shaft it is preferably perpendicular surface portion composed of a plane perpendicular to the direction a _0. With such a configuration, the length of the vertical surface portion can be adjusted even in a factory or a construction site.

The connecting surface portion 13a formed of the inclined surface portion has a contour line shape substantially the same as the cross section orthogonal to the axial direction of the rod-shaped main body portion 11. Further, in the example shown in the figure, the connection surface portion 13a has substantially the same contour line shape as the other connection surface portion 12. The substantially same contour line shape is not limited as long as it fits in the human hand, but is, for example, a rectangle. With such a shape, the shape of the other connecting surface portion 12a formed of the vertical surface portion can also be a rectangle having substantially the same contour line shape. As a result, it becomes easy to make the connecting surface portion 13a formed of the inclined surface portion substantially the same contour line shape as the other connecting surface portion 12a. A chamfered portion may be provided at each corner of the rectangle. Typical dimensions when the contour line shape is rectangular are 20 to 100 mm in length and 20 to 100 mm in width.

With this configuration, the designability when installed as a handrail is improved. Further, as shown in FIG. 2, in the other handrail member 10 according to the present embodiment, the end portion 13 including the inclined surface portion 13a of the rod-shaped main body portion 11 has the outer surface 11b of the end portion 13 and the inclined surface portion 13a. It includes an outer flat portion 13b having a _{normal line A 2} that is substantially perpendicular to the normal line A _1. At this time, the inclined surface portion 13a and the outer flat surface portion 13b form a corner portion substantially perpendicular to each other. The angle between the normal line A ₁ and the normal line A ₂ does not necessarily have to be approximately a right angle, but if the angle is approximately right angle, the handrail is constructed by connecting to a connecting surface portion composed of a vertical surface portion of another handrail member. The design of the time is improved.

The handrail member 10 according to the present embodiment is excellent in designability, even if the handrail has a bending point, its angle can be freely adjusted by precut processing, the number of member points can be reduced, and the design is excellent. Therefore, the handrail member 10 according to the present embodiment is suitable for, for example, a handrail member for stairs.

In addition, it is possible to reduce contact scratches when connecting to other handrail members. The material of the flat plate-shaped spacer 19 is not limited, and is, for example, metal, hard resin, soft resin, or the like.

If the spacer 19 is too thin, the shape difference between the connecting surface portions becomes conspicuous and the design property is deteriorated. Therefore, the thickness of the spacer 19 is preferably 1.0 mm or more. More preferably 1.5 mm or more. Further, if it is too thick, the spacer 19 becomes conspicuous, and conversely, the design property is deteriorated. Therefore, the thickness is preferably 3.0 mm or less. More preferably 2.5 mm or less. If the spacer 19 is even slightly larger than the connecting surface portion, it becomes conspicuous and deteriorates the design. Therefore, the spacer 19 is made smaller than the connecting surface portion, that is, between the handrail member 10 and the other handrail member 100. It is preferable that the spacer 19 forms a groove in the space. However, if the depth of the groove is too shallow, the shape difference between the connecting surface portions becomes conspicuous and the design property is deteriorated. Therefore, the depth is preferably 1.0 mm or more. More preferably 1.5 mm or more. Further, if it is too deep, it becomes easy for the user to catch or pinch a finger, and the usability deteriorates (especially when the spacer 19 is thick, the deterioration becomes remarkable), so the depth is 3.0 mm or less. do. More preferably 2.5 mm or less.
