In the invention of Patent Document 1, in order to make the angle between the handrail members adjustable, the end of one handrail member has a semicircular convex cross section, and the end of the other handrail member has a semicircular concave cross section. It is difficult to process and is inferior in productivity. Not only that, the end of the semicircular concave cross section may be chipped. Further, depending on the connection angle, a part of the curved surface at the end of the convex cross section may be exposed, which may deteriorate the design.

As in Patent Document 2 and Patent Document 3, if a connecting member (end cap) that connects the ends of the handrail member is used, the connecting portion can be hidden, but a foreign material made of metal, resin, or the like can be hidden. It will be fixed at, and it will not look good. In particular, in the case of handrail members made of laminated lumber or solid wood of natural wood, the designability is significantly deteriorated.

The handrail according to the present embodiment connects handrail members (first handrail member and second handrail member) having different installation angles at the corners of the stairs. First, a handrail member that can be used for the handrail according to the present embodiment will be described, and then the handrail according to the present embodiment and a method for manufacturing the same will be described.

1. 1. Handrail member according to the present embodiment As shown in FIG. 1, the handrail member 10 that can be used for the handrail according to the present embodiment includes, for example, a rod-shaped main body portion 11 extending in one direction (direction X in the figure). ing. 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 preferably has a substantially constant contour line shape in a cross section perpendicular to the axial direction _A0 in the length direction thereof. The rod-shaped main body portion 11 has connection surface portions 12a and 13a at both end portions 12 and 13. However, the rod-shaped main body portion 11 may have a connection 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. 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 portion 13a is an inclined surface portion having a normal line A1 _inclined with respect to the axial direction A0 of the rod-shaped main body portion 11. The other connecting surface portion 12a is a vertical surface portion composed of a surface perpendicular to the axial direction _A0 . The other connection surface portion 12a may be an inclined surface portion similar to the connection surface portion 13a, but from the viewpoint of reducing manufacturing cost by standardizing parts and from the viewpoint of designability, as shown in the example of the figure, the shaft It is preferable that the vertical surface portion is composed of a surface perpendicular to the direction _A0 . 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 _A0 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 is a shape that fits in the human hand, but is, for example, a rectangle. With such a shape, the shape of the other connecting surface portion 12a composed of the vertical surface portions can also be a rectangle having substantially the same contour line shape. As a result, it becomes easy to make the connection surface portion 13a formed of the inclined surface portion substantially the same contour line shape as the other connection surface portion 12a. A chamfered portion may be provided at each corner of the rectangle. When the contour line shape is rectangular, the typical dimensions are 20 to 100 mm in length and 20 to 100 mm in width.

In particular, at the end portion 13 of the rod-shaped main body portion 11 including the inclined surface portion 13a, a plane (a plane having _a normal line A1) constituting the inclined surface portion 13a is inside the side surface on the side inclined with respect to the axial direction _A0 . When the side surface 11a and the opposite side thereof are the outer surface 11b, it is preferable that the inclined surface portion 13a is provided between the surface including the inner side surface 11a and the surface including the outer surface 11b. With this configuration, the designability when installed as a handrail is improved. Further, as shown in FIG. 2, the other handrail member 10 has an end portion 13 provided with an inclined surface portion 13a of the rod-shaped main body portion 11, an outer surface 11b of the end portion 13, and _a normal line A1 of the inclined surface portion 13a. It is provided with an outer flat surface portion 13b having a normal line _A2 forming a substantially right angle. At this time, the inclined surface portion 13a and the outer flat surface portion 13b form a corner portion substantially at right angles. The angle between the normal line A ₁ and the normal line A ₂ does not necessarily have to be a substantially right angle, but if the normal line A 1 and the normal line A 2 are formed at a substantially right angle, the designability when connected to another handrail member and constructed as a handrail is improved.

Even if the handrail member 10 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 is suitable for, for example, a handrail member for stairs.

2. 2. Handrails of the present embodiment As shown in FIG. 3, the handrails of the present embodiment are installed, for example, on the outer wall of the stairs. At this time, for example, a start handrail member S is provided at the lowest position along the ascending angle of the stairs, and at the landing position, the start handrail member S has an intermediate handrail member C parallel to the dance scene. Be connected. The angle of the inclined surface portion of the start handrail member S is set by the ascending angle of the stairs and is precut in advance.

Then, in the stairs portion further up from the landing, when viewed from the vertical direction, a front wall (not shown) is constructed at right angles to the first wall (not shown) on which the starting handrail member S is installed. The handrail is installed on this wall surface. That is, the handrail member CS is provided in the direction parallel to the dance scene, and the intermediate handrail member C is sequentially connected along the ascending angle of the stairs. Here, when viewed from the vertical direction, a second wall (not shown) is constructed at right angles to the front wall (not shown), and the handrail member CS, the intermediate handrail member C, and the intermediate handrail are constructed on this wall. The member C and the handrail member E for the end are connected. After connecting a plurality of handrail members in advance, they may be attached to the wall surface via a bracket, or may be fixed to the wall surface and connected to each other in parallel.

The handrail according to the present embodiment is a handrail that connects handrail members having different installation angles at the corners of the stairs, and in the example shown in FIG. 3, a handrail member CS and another handrail member (for example, an intermediate handrail member C). Are suitable. Hereinafter, a more specific description will be given.

As shown in FIG. 4, the handrail 300 according to the present embodiment includes a first handrail member 100 and a second handrail member 200. The first handrail member 100 includes a rod-shaped main body portion 110 having a substantially rectangular contour line shape in a cross section orthogonal to the axial direction, and a connecting surface portion 111 with another handrail member is provided at at least one end of the rod-shaped main body portion 110. Be prepared. The second handrail member 200 includes a rod-shaped main body portion 210 whose contour line shape of a cross section orthogonal to the axial direction is substantially the same as the contour line shape of the first handrail member 100. Then, in the handrail 300 according to the present embodiment, the connection surface portion 111 of the first handrail member 100 and the end side surface portion 211 of the second handrail member 200 are arranged so as to face each other, and the connection surface portion of the first handrail member 100 is arranged. The upper side 111a of the 111 and the upper side 211a of the end side surface 211 of the second handrail member 200 are substantially parallel to each other, and are arranged so that their positions in the vertical direction are substantially the same.

The connection surface portion 111 of the first handrail member 100 and the end side surface 211 of the second handrail member 200 are arranged so as to face each other so that the connection surface portion 111 and the end side surface 211 face each other at a substantially constant interval. It means that it is placed. The distance between the connection surface portion 111 and the end side surface portion 211 is preferably in the range of 0 to 20 mm. This interval may be 0 mm (in contact), but is preferably more than 0 mm (not in contact). A preferred lower limit is 1 mm, and a further preferred lower limit is 2 mm. A more preferable upper limit is 15 mm, a further preferable upper limit is 10 mm, and a further preferable upper limit is 5 mm. Further, it may or may not be connected by a position adjusting jig or the like described later.

Since the handrail 300 according to the present embodiment has such a configuration, it can be easily installed, the connection surface is not exposed, and the upper surface of the first handrail member 100 and the second handrail member are not exposed. Since there is almost no step on the upper surface of the 200, the design is extremely excellent.

The upper side 111a of the connection surface portion 111 of the first handrail member 100 and the upper side 211a of the end side surface 211 of the second handrail member 200 are substantially parallel to each other, and the positions in the vertical direction are not only substantially the same, but also the first. It is preferable that the side surface of the connecting surface portion 111 of the 1 handrail member 100 and the cross section of the end portion of the second handrail member 200 are on substantially the same plane, because the design is further improved.

In the example shown in FIG. 4, the rod-shaped main body portion 210 of the second handrail member 200 includes a horizontal portion 210a and an inclined portion 210b. The upper surface (second horizontal upper surface 213) of the horizontal portion 210a is horizontal. The upper surface of the inclined portion 210b is inclined with respect to the upper surface of the horizontal portion 210a. As a result, the upper side 111a of the connection surface portion 111 of the first handrail member 100 and the upper side 211a of the end side surface 211 of the second handrail member 200 are arranged so as to be substantially parallel and substantially the same in the vertical direction. It will be easier. The length L (length in the x direction in the figure) of the horizontal portion 210a should be in the range of 1.0 to 3.0 times the width W (length in the x direction in the figure) of the first handrail member 100. .. Within this range, the design is excellent.

The example shown in FIG. 4 is an embodiment in which the connecting surface portion 111 of the first handrail member is formed of a surface orthogonal to the axial direction, but the embodiment is not limited to such an embodiment. That is, as shown in FIG. 5, the connection surface portion 111 of the first handrail member has a normal line inclined with respect to the axial direction of the rod-shaped main body portion 110, and is substantially a cross section orthogonal to the axial direction of the rod-shaped main body portion. It may have a configuration having an inclined surface portion 112 having the same contour line shape, and may be arranged so that the inclined surface portion 112 as a connecting surface portion and the end side surface 211 of the second handrail member 200 face each other.

There is.

As shown in FIGS. 7 and 8, the handrail 400 according to another embodiment includes a position adjusting jig 500. The position adjusting jig 500 adjusts the positions of the inclined surface portion 112 as the connecting surface portion of the first handrail member 100 and the end side surface 211 of the second handrail member 200. As the position adjusting jig 500, it is preferable to use a material such as metal or resin that requires sufficient strength.

If the difference (step) is too small, the step between the first handrail member 100 and the second handrail member 200 becomes conspicuous, and if it is too large, the design becomes poor, so the difference is set to 1.0 to 3.0 mm. Is good. Further, not only the difference between the upper sides but also the steps on both sides (left side and right side), that is, the horizontal position of the left side (or right side) of the vertical plate portion 501 and the connection surface portion of the first handrail member 100. The difference (step) from the horizontal position of the left side (or right side) of the (inclined surface portion) 112 or the left side (or right side) of the end side surface 211 of the second handrail member 200 may be small from the viewpoint of design. It is preferably 1.0 to 3.0 mm.

The position adjusting jig 500 includes a vertical plate portion 501 and a horizontal plate portion 502. Regarding the thickness of the vertical plate portion 501 and the horizontal plate portion 502, in the examples shown in FIGS. 7 and 8, the vertical plate portion 501 is connected to the inclined surface portion (connecting surface portion) 112 of the first handrail member 100, and the horizontal plate portion 502.

It may be configured to be connected to the first horizontal lower surface 114 including the lower side. Further, by inserting and tightening a fastener such as a screw into the through holes 501a and 501b provided in the vertical plate portion 501 and the through holes (not shown) provided in the horizontal plate portion 502, the first handrail member 100 and the first handrail member 100 It may be configured to fix the second handrail member 200.

The thickness of the vertical plate portion 501 and the horizontal plate portion 502 is preferably 1.0 to 5.0 mm. This is because if it is too thin, it becomes difficult to adjust the step, and if it is too thick, it becomes heavy and the workability deteriorates. At the time of construction, it is recommended to provide a tip hole on the surface (connecting surface portion or end side surface) of the handrail member connecting the vertical plate portion 501 at a position corresponding to the through hole (501a, 501b) of the vertical plate portion 501. good. This facilitates the adjustment of the fixed position. The through hole of the vertical plate portion 501 or the horizontal plate portion 502 (particularly, the through hole of the horizontal plate portion) may be a long hole that is long in the vertical direction or the horizontal direction. This facilitates fine adjustment of the fixed position. Further, on the surface (second horizontal lower surface) connecting the horizontal plate portion 502 of the handrail member, a tip hole is provided at a position corresponding to the through hole of the horizontal plate portion 502, or a screw is embedded by embedding a demon nut. It is better to provide a hole.

The second horizontal lower surface 214 including the lower side of the end side surface 211 of the second handrail member 200 preferably includes a notch 214a for accommodating the position adjusting jig 500. With this configuration, the position adjusting jig 500 fits better.
