Description

  The present invention relates to a wooden handrail attached to, for example, an indoor staircase or a corridor.

  As shown in Patent Document 1, a wooden handrail with a circular cross section is often used for wooden stairs installed indoors such as general wooden houses, corridors with wooden floors, and the like. Although such a round bar type handrail has a wood texture, it lacks volume and profound feeling, cannot wipe out a reasonable impression, and it is difficult to obtain a high-class feeling.

  Conventionally, as a method of giving a high-class feeling to the handrail, a volume feeling is obtained by forming a square cross-sectional shape having a corner (edge) on the surface, or by increasing the vertical direction (height) dimension and thickness dimension. The method of giving

  For example, the handrail shown in Patent Document 2 has an L-shaped cross-sectional shape having a vertical piece and a horizontal piece continuously extending in the handrail length direction, the tip of the horizontal piece is fixed to the indoor wall surface, and the vertical piece is It arrange | positions in parallel with the wall surface in the state spaced apart from the wall surface. The user attaches the thumb to the non-wall surface side (front surface side) of the vertical piece, attaches the remaining four fingers to the wall surface side (back side) of the vertical piece, and places the palm on the upper end of the vertical piece. I walk while walking.

  However, in the conventional handrail shown in Patent Document 2, since the entire front end surface of the horizontal piece continuously formed in the length direction is in contact with the wall surface, the lower side of the gap between the vertical piece and the wall surface. The side is closed by a horizontal piece. For this reason, when the user's hand is large or when trying to grasp the handrail deeply and trying to insert a finger deeply into the back side of the vertical piece, the tip of the index finger or middle finger will accidentally hit the horizontal piece, There was a problem that people felt uncomfortable.

  Further, in the above-described conventional handrail, dust floating in the air from above enters the gap between the vertical piece and the wall surface, so that the dust immediately accumulates on the horizontal piece. For this reason, it is necessary to frequently remove the dust on the horizontal piece in the cleaning operation, which causes a problem that the cleaning operation is troublesome.

  The present invention has been made in view of the above problems, and while ensuring a sufficient high-class feeling, it is possible to prevent a problem that the fingertip hits an unexpected part and to easily perform a cleaning operation. The purpose is to provide a wooden handrail.

  In order to achieve the above object, the present invention has the following structure.

  1 to 4 are views showing a handrail structure according to an embodiment of the present invention. In this embodiment, this handrail structure is assembled on the side wall of an indoor wooden staircase.

  As shown in these drawings, in the handrail structure of the present embodiment, a wooden handrail body 1, a wooden bracket 2 for supporting the handrail body 1 on the wall surface W, and the bracket 2 are connected to the handrail body 1. A metal connection fitting 3 for fixing is provided as a basic component.

  The handrail main body 1 has the same cross-sectional shape at any position in the length direction, and will be described later in detail. However, the handrail main body 1 is generally a vertically long non-circular cross-sectional shape whose height dimension is longer than the thickness dimension. have.

  In this embodiment, the handrail main body 1 is arranged along the wall surface W, and the surface on the side (wall surface side) facing the wall surface W is configured as the back surface (the left surface in FIG. 1). The surface on the opposite side (non-wall surface side) is configured as the surface (the right surface in FIG. 1). In the present embodiment, the upper surface in FIG. 1 of the handrail body 1 is configured as an upper surface, and the lower surface is configured as a lower surface.

  The handrail main body 1 has a grip portion 11 that protrudes on the back side on the upper side on the back side thereof, and is continuously formed in the length direction of the handrail main body 1 (handrail length direction). A bracket mounting portion 12 protruding in the direction of the handrail length is formed continuously. Further, between the grip portion 11 and the bracket mounting portion 12 on the back surface side of the handrail main body 1, finger hooking grooves 13 that are open to the back surface side are formed continuously in the handrail length direction.

  The grip part 11 is formed on a flat inclined surface on a cross-sectional straight line in which an upper part 111 from the upper end to the rear surface protruding part is inclined downward toward the rear surface side. Further, the lower side portion 112 from the lower end edge of the upper side portion 11 to the finger hanging groove 13 in the grip portion 11 is formed in a curved surface (curved surface) with R.

  As will be described later, the grip portion 11 has four fingers (index finger, middle finger) except the thumb when the handrail body 1 is grasped by hand as shown by an imaginary line (two-dot chain line) in FIG. , Ring finger, little finger). In this embodiment, since the upper part 111 of the grip part 11 is formed on a straight line, the base part of the finger fits in the gripped state, and the lower part 112 is formed on a curved surface. Therefore, the part from the middle of the finger to the fingertip fits.

  Here, in the conventional round bar type handrail, the diameter (φ) is set to 35 mm in consideration of ease of gripping. Therefore, in the present embodiment, the curvature radius of the lower side portion 112 of the grip portion 11 is formed to 35/2 mm in consideration of ease of gripping.

  Moreover, in this embodiment, when the grip part 11 is gripped, the fingertips of fingers other than the thumb fit into the finger-hanging groove 13 so that a good grip state can be obtained.

  The bracket mounting portion 12 of the handrail main body 1 is formed in a rectangular shape having a vertically long cross section. In the construction state, the upper end surface is a flat surface arranged horizontally and the back surface (tip surface) is arranged vertically. It becomes a flat surface.

  The height dimension of the bracket mounting portion 12 is formed to be slightly larger than the thickness dimension of the bracket 3 and is set to 30 mm in this embodiment.

  As shown in FIG. 3, the protruding amount (projecting dimension) A11 of the grip portion 11 is formed larger than the protruding amount A12 of the bracket mounting portion 12, and when the handrail body 1 is viewed from directly above, the grip portion 11, the entire bracket mounting portion 12 is concealed so that the bracket mounting portion 12 is not visually recognized. In other words, in the construction state, the tip of the grip portion 11 is disposed at a position closer to the wall surface W than the tip of the bracket mounting portion 12.

  In the present embodiment, it is preferable that the protrusion amount A11 of the grip portion 11 is formed to be larger than the protrusion amount A12 of the bracket portion 12 by 5 mm or more so that the bracket portion 12 is more reliably concealed by the grip portion 11. .

  In the present embodiment, the finger groove 13 corresponds to the depth of the finger groove 13 so that when the handrail main body 1 is gripped with a hand, the fingertip engagement (grip) is good as described above. The protrusion amount A11 (see FIG. 3) of the grip portion 11 is set to 12 mm or more, preferably about 15 mm.

  The upper end surface of the handrail main body 1 is formed as a flat surface, and is arranged horizontally in the construction state.

  The upper part 141 on the surface of the handrail body 1 is formed on a flat surface that is vertically arranged in the construction state, and the lower side part 142 is a flat surface that is inclined so as to gradually approach the wall surface side in the construction state. It is formed on an inclined surface. In the present embodiment, when the handrail body 1 is gripped, the abdomen of the thumb comes into contact with the lower side portion 142 on the surface side of the handrail body 1. As a result, the handrail body 1 can be gripped comfortably in a natural state without placing a burden on the thumb and the four fingers other than the thumb.

  An edge line (edge portion) 51 is formed between the upper side portion 141 and the lower side portion 142 on the surface of the handrail body 1, and the presence of the edge line 51 improves the design of the surface shape of the handrail body 1. As a result, a sense of luxury is increasing.

  Similarly, an edge line 52 is also formed between the upper end surface and the surface of the handrail main body 1, and an edge line (edge portion) 53 is also formed between the upper end surface of the handrail main body 1 and the grip portion 11. With the edge lines 52 and 53, the square cross-sectional shape of the handrail main body 1 is emphasized, and the sense of quality is further increased.

  Moreover, in this embodiment, the vertical dimension (height dimension) of the handrail main body 1 is formed to about 80 mm. In the present embodiment, the height of the handrail body 1 is preferably set to 60 mm to 100 mm, more preferably 70 mm to 90 mm. That is, when this height dimension is too small, the profound feeling becomes poor, and it may be difficult to ensure a sufficient luxury feeling. On the other hand, when the height dimension is too large, only the handrail body 1 is conspicuous, and the balance with the peripheral portion is deteriorated, and there is a possibility that a good aesthetic appearance cannot be obtained. In other words, when the height dimension is specified in the above range, a sufficient high-class feeling can be surely obtained.

  In the present embodiment, the height dimension of the handrail body 1 is a length dimension between the upper end surface and the lower end surface of the handrail body 1 in a cross section orthogonal to the handrail length direction. That is, the height dimension of the handrail main body 1 of the present embodiment is different from the vertical dimension when the handrail main body 1 is obliquely constructed on the wall surface W as a handrail for stairs.

  In the present embodiment, the material of the handrail main body 1 is a laminated material in which the fiber direction coincides with the handrail length direction. Needless to say, the material of the handrail body 1 is not particularly limited as long as it is a wood-based material such as a wood-made material or a wood-like material (including artificial wood), and any material can be used. Can do. In addition to the laminated material, for example, a laminated material, a solid material, or the like can be suitably used. Of course, it is more preferable to use a laminated material as in the present embodiment in consideration of texture, design, economy, and the like.

  As shown in FIGS. 7 to 10, the bracket 2 is for supporting the handrail body 1 on the wall surface W and is disposed between the wall surface W and the handrail body 1. In the present embodiment, the upper side and the lower side of the paper in FIG. 8 are referred to as “upper side” and “lower side” of the bracket 2, and the horizontal direction in FIG.

  The bracket 2 is formed in a block shape having a rectangular shape in plan view, and is disposed in correspondence with the wall surface corresponding surface 21 constituted by one end surface that can contact the wall surface W and the bracket mounting portion 12 of the handrail main body 1. And a handrail main body corresponding surface 22 constituted by the other end surface.

  The handrail main body corresponding surface 22 of the bracket 2 is formed with a concave portion in the middle portion excluding the front and rear end portions thereof to form a connecting fitting mounting concave portion 221. The handrail body corresponding surface 22 is configured such that a portion corresponding to the connecting bracket mounting recess 221 can be brought into contact with the bracket portion 12 of the handrail body 1 via the connecting bracket 3 described later, and both front and rear ends excluding the recess 221. The portion is configured to be able to directly contact the bracket portion 12 of the handrail main body 1.

  Three counterbore recesses 222 are formed on the handrail body-corresponding surface 22 of the bracket 2 at an appropriate interval in the handrail length direction (front-rear direction). Each counterbore recess 222 is formed with a screw insertion hole 223 that penetrates the bracket 2 in the width direction (left and right direction in FIGS. 1 and 2) from the bottom surface of the recess 222 and opens on the wall surface 21. .

  Each screw insertion hole 223 is formed by shifting the position in the vertical direction so as not to be arranged side by side on a straight line in the front-rear direction. Specifically, the central screw insertion hole 223 is disposed at a position lower than the front and rear screw insertion holes 223.

  On the lower surface of the bracket 2, an intermediate portion excluding the front and rear end portions, in other words, a portion corresponding to the connection fitting mounting recess 221 is formed as a recess to form a connection fitting mounting recess 224. Two embedded nuts 225 are fixed in an embedded state on the bottom surface of the connecting bracket mounting recess 224 (see FIGS. 1 and 2). Each burying nut 225 is formed by shifting the position in the width direction and the front-rear direction. Specifically, the front buried nut 225 is disposed closer to the wall surface 21 than the rear buried nut 225.

  In addition, the bracket 2 is formed such that a corner portion between the front and rear end surfaces and the upper and lower surfaces is a curved surface (curved surface) with an R, and an acute corner portion (edge portion) is not formed. Since the edge portion is not formed in this way, even when the fingertip touches both the front and rear ends of the upper surface of the bracket 2 when trying to grip the handrail body 1 as described later, there is no sense of incongruity when touching the edge portion. It is like that.

  The bracket 2 is formed such that the thickness dimension between the upper surface and the lower surface is smaller than the vertical dimension of the bracket mounting portion 12 of the handrail main body 1, and the handrail main body corresponding surface 22 of the bracket 2 is the bracket mounting portion 12 of the handrail main body 1. It can be arranged in a state of being surely contained within the range in the vertical direction. Specifically, the vertical dimension of the bracket mounting portion 12 is 30 mm, and the thickness dimension of the bracket 2 is 27 mm.

  In the present embodiment, of the entire outer surface of the bracket 2, the region excluding the wall surface 21 and the handrail body surface 22, that is, both the upper and lower side surfaces and the front and rear side surfaces are configured as open surfaces.

  In the present embodiment, the material of the bracket 2 is a laminated material in which the fiber directions coincide with the direction orthogonal to the front-rear direction (length direction) corresponding to the handrail length direction. Needless to say, the material of the bracket 2 is not particularly limited as long as it is a wood-based material such as a wood-made material or a wood-like material (including artificial wood), and any material can be used. it can. In addition to the laminated material, for example, a laminated material, a solid material, or the like can be suitably used. Of course, it is more preferable to use a laminated material as in the present embodiment in consideration of texture, design, economy, and the like.

  As shown in FIGS. 1, 2, and 6, the connection fitting 3 constitutes a connection tool for fixing the bracket 2 to the handrail body 1 and has a substantially L-shaped cross section. This connection metal fitting 3 has the board | substrate 31 arrange | positioned horizontally in the construction state, and the attachment piece 32 arrange | positioned vertically. The thickness and outer peripheral shape of the substrate 31 correspond to the depth and shape of the coupling fitting mounting recess 224 on the bottom surface of the bracket 2, so that the substrate 31 fits in the coupling fitting mounting recess 224 and is well accommodated. Is formed.

  Further, the thickness and outer peripheral shape of the mounting piece 32 correspond to the depth and shape of the connecting bracket mounting recess 221 on the handrail body-corresponding surface 22 side of the bracket 2, and the mounting piece 32 fits well in the connecting bracket mounting recess 221. It is configured to be accommodated in a conforming state.

  Two screw insertion holes 311 are formed in the base plate 31 of the connection fitting 3 so as to correspond to the embedded nut 225 of the bracket 2. The screw insertion hole 311 is formed in a long hole shape that is long in the front-rear direction corresponding to the handrail body length direction.

  A plurality of screw insertion holes 321 are formed in the attachment piece 32. Each screw insertion hole 321 is formed by appropriately shifting the position in the front-rear direction and the vertical direction. Specifically, the screw insertion holes 32 at both front and rear ends are disposed above the two screw insertion holes 32 positioned therebetween.

  Further, the mounting piece 32 of the connection fitting 3 is formed so that its vertical dimension is slightly smaller than the vertical dimension of the bracket mounting part 12 in the handrail body 1, and the entire area of the mounting piece 32 is the back surface (tip surface) of the bracket mounting part 12. Can be touched.

  A positioning locking piece 33 that is bent outward (toward the handrail main body) is formed at the tip edge (upper edge) of the mounting piece 32. The positioning locking piece 33 is locked to the upper surface of the bracket mounting portion 12 in the handrail main body 1 so that the connection fitting 3 is positioned in the vertical direction with respect to the handrail main body 1. Here, in this embodiment, the upper surface of the bracket attaching part 12 is comprised as a to-be-latched part.

  In the present embodiment, the connection fitting 3 is made of a metal, and is formed by bending a metal plate.

  In this embodiment, a handrail structure is formed by assembling and constructing the handrail body 1 on the wall surface W using the bracket 2 and the connecting fitting 3 as described below.

  First, the connection fitting 3 is attached to the handrail main body 1. In other words, the mounting piece 32 of the connection fitting 3 is arranged along the position where the bracket mounting portion 12 of the handrail body 1 is to be fixed to the wall surface W. At this time, by positioning the positioning piece 33 of the connection fitting 3 to the upper end surface of the bracket mounting portion 12 of the handrail main body 1, the vertical positioning of the connection fitting 3 with respect to the handrail main body 1 can be accurately achieved.

  In this way, the attachment piece 32 of the coupling fitting 3 is arranged on the bracket attachment portion 12 of the handrail body 1, and the screw 42 such as a tapping screw is inserted into the screw insertion hole 321 of the attachment piece 32, thereby the bracket of the handrail body 1. Screw into the mounting part 12. Thereby, the connection metal fitting 3 is fixed to the predetermined position of the handrail main body 1.

  It should be noted that a tip hole (bottom hole) is formed in advance at the screwing position of the screw 42 in the bracket mounting portion 12 of the handrail main body 1, so that when the screw 42 is screwed into the handrail main body 1, the handrail main body 1 is broken. It is possible to effectively prevent the occurrence of defects.

  Here, in the present embodiment, the screw 42 for fixing the connecting fitting 2 to the handrail body 1 is configured as a second fixing tool.

  In the present embodiment, the pitch between the adjacent brackets 2 and 2 is adjusted to within 1000 mm with respect to the mounting pitch of the connecting fitting 3 in the handrail main body 1, that is, the mounting pitch of the bracket 2, and at the end of the handrail main body 1. The distance between the mounting center position of the bracket 2 and the end of the handrail main body 1 is adjusted to about 100 mm to 200 mm. That is, if this distance is too long, the strength when the end is held by hand may be insufficient, and if it is too short, the aesthetics may be reduced.

  Next, the bracket 2 is fixed at a position corresponding to the connection fitting 3 of the handrail main body 1 on the wall surface W. In this case, the bracket 2 is temporarily fixed to the handrail main body 1, and the handrail main body 1 with the bracket is temporarily placed (temporarily arranged) at the construction position on the wall surface W, so that the fixing position of the bracket 2 is accurately grasped. Is good. That is, before the bracket 2 is directly fixed to the wall surface W, the board 31 in the connecting bracket 3 of the handrail body 1 is accommodated in the connecting bracket mounting recess 224 on the lower surface side of the bracket 2, and the mounting piece 32 is mounted on the handrail in the bracket 2. It arrange | positions so that it may accommodate in the connection metal fitting attachment recessed part 221 of the main body corresponding | compatible surface 22. FIG. In this state, a screw (bolt) 43 is inserted into the screw insertion hole 311 of the base plate 31 of the connection fitting 3 from the lower side and lightly fastened in the embedded nut 225 of the bracket 2, and the bracket 2 is connected to the connection fitting 3. Then, it is fixed (temporarily fixed) to the handrail main body 1 in a temporarily fixed state. Thereafter, the handrail body 1 with the bracket is temporarily placed at the construction position on the wall surface W as described above, and a mark is given to the position (bracket fixing position) where the bracket 2 is in contact with the wall surface W in that state. Keep it. Next, after loosening the screw 43 and removing the bracket 2 from the handrail body 1, the bracket 2 is fixed to the wall surface W alone.

  When the bracket 2 is fixed to the wall surface W, the countersunk concave portion of the handrail main body corresponding surface 22 of the bracket 2 in a state where the wall surface corresponding surface 21 of the bracket 2 is along the position where the above-mentioned mark is provided on the wall surface W. A screw 41 such as a tapping screw inserted through 222 and the screw insertion hole 223 is screwed into the wall surface W. Thereby, the bracket 2 is fixed to a predetermined position on the wall surface W.

  Here, in the present embodiment, the screw 41 that fixes the bracket 2 to the wall surface W is configured as a first fixing tool.

  Thereafter, the connection fitting 3 fixed to the handrail body 1 is arranged along the bracket 2 fixed to the wall surface W. In this case, it arrange | positions so that the board | substrate 31 and the attachment piece 32 of the connection metal fitting 3 may each be accommodated in the connection metal fitting attachment recessed parts 221,224 of the bracket 2 by the wall surface W side. In this state, the screw 43 is inserted into the screw insertion hole 311 of the base plate 31 of the connection fitting 3 and firmly fixed to the embedded nut 225 of the bracket 2 by being firmly fixed. Accordingly, the bracket 2 and the connection fitting 3 are fixed, and the handrail body 1 is supported and fixed to the wall surface 2 via the bracket 2 and the connection fitting 3.

  Note that the screw insertion hole 311 in the base plate 31 of the connection fitting 3 is constituted by a long hole extending in the handrail length direction, so that there is some difference between the handrail body 1 and the bracket 2 fixed to the wall surface W due to an error or the like. Even if there is a misalignment, the position in the length direction between the handrail body 1 and the bracket 2 can be adjusted within the range in the length direction of the screw insertion hole 311 which is a long hole. Accuracy can be reliably maintained.

  Here, in the present embodiment, a screw 43 for fixing the connection fitting 3 to the bracket 2 is configured as a third fixing tool.

  In the handrail structure of the present embodiment assembled in this way, the length in the vertical direction of the handrail main body 1 is large, and the thickness between the front surface and the back surface is also formed sufficiently thick, so that a heavy feeling and a high-class feeling are achieved. An overflowing high quality wooden handrail structure can be obtained.

  Furthermore, in the handrail structure of the present embodiment, the handrail body 1 is formed in a vertically long square cross-sectional shape, so that it is more profound and more luxurious than the round bar-type handrail that has been the mainstream in the past. You can definitely get it. In particular, in the present embodiment, as described above, the angle between the upper side portion 141 and the lower side portion 142 on the surface of the handrail main body 1 is changed, and the edge line 51 is formed between them. Can be obtained.

  Further, in the present embodiment, since the grip portion 11 is formed on the upper side portion on the back surface side of the handrail main body 1 so as to protrude to the back surface side, the user has the remaining four thumbs on the front surface side of the handrail main body 1. When the fingers are placed and gripped on the back side, the thumb is comfortably placed with the belly portion along the lower side 142 of the surface of the handrail body 1, and the remaining four fingers are gripped. It arranges without difficulty along the outer peripheral surface of the part 11. Thus, since each finger can grip the handrail body 1 without difficulty in a natural state, the user can ascend and descend the stairs without anxiety.

  Further, in the present embodiment, as described above, since the upper portion 111 of the grip portion 11 is formed on a flat inclined surface, the base portion of the four fingers other than the thumb fits to the upper portion 111. Thus, the handrail body can be gripped without difficulty in a more natural state.

  Furthermore, in this embodiment, since the finger groove 13 is formed below the grip portion 11 on the back side of the handrail body 1, when the user grips the handrail body 1 with a relatively strong force, the thumb The fingertips of the other four fingers fit in the finger-hanging groove 13 and the fingertips of the four fingers come into contact with the region from the bottom surface of the finger-hanging groove 13 to the lower end of the outer peripheral surface of the grip portion 11. Thereby, the user can grip the handrail body 1 in a more stable state, and can move up and down the stairs more smoothly.

  Moreover, in this embodiment, since the handrail main body 1 is assembled | attached in the state spaced apart from the wall surface W via the bracket 2, the lower side of the clearance gap between the handrail main body 1 and the wall surface W is open | released below. For this reason, even if the user inserts four fingers other than the thumb straightly and deeply into the back side of the handrail body 1, the finger is placed in the gap on the back side of the handrail body 1. The parts do not interfere with each other, and you do not feel uncomfortable.

  In addition, when a finger other than the thumb is inserted deeply into the back side of the handrail body 1 at the mounting position of the bracket 2 in the handrail body 1, the fingertip may contact the bracket 2, but the length of the handrail body 1 In the range, the area where the bracket 2 exists is very small, and therefore, the possibility that the fingertip contacts the bracket 2 is very low.

  Even if the fingertip touches the bracket 2, there is no great discomfort. That is, since the corner portion between the both end surfaces of the bracket 2 in the handrail length direction (front-rear direction) and the upper surface is formed as a curved surface with R, that is, an acute corner portion (edge portion) is not formed. The fingertips do not feel uncomfortable when touching the edge.

  Furthermore, in this embodiment, since the back side of the handrail body 1 is opened downward, even if dust floating in the air enters the back side of the handrail body 1, the dust adheres to the handrail body 1. Can be prevented.
