1. The shape determination method of the handrail member which concerns on this embodiment The shape determination method of the handrail member which concerns on this embodiment is a method of determining the shape of a pre-cut handrail member, Comprising: The following (1)-(3) steps are provided. .
(1) A step of acquiring staircase pattern information inputted by a user and dimensional information of staircase components,
(2) A step of determining a combination condition of handrail members necessary for construction based on the step pattern information,
(3) determining a shape of the handrail member based on dimensional information of the staircase constituent member;
Step to determine the matter.

  Accordingly, the user can determine the combination condition and size (length, angle) of the handrail member appropriate for the stairs to be constructed only by inputting the stairs pattern and the dimensions of the constituent members of the stairs.

1-1. Input information acquisition step (step (1) above)
In this step, the stairs pattern information input by the user and the dimensional information of the stairs constituent members are acquired. Here, the staircase pattern information includes the general configuration, the distinction and order of the direct steps / around steps / landings, the number of steps of the direct steps / around steps, the direction of the surrounding steps (clockwise, counterclockwise), the presence / absence of landings, etc. Information.

  The schematic configuration is, for example, an I type (stair consisting of only a straight stage), an L type (a stair consisting of a straight stage and a stage around 90 °), a U type (a straight stage, a stage around 180 ° and a straight stage). Stairs), J type (stairs composed of straight and 180 ° steps), C type (at least including 90 ° steps, straight steps and 90 ° steps), G type (at least , Including 90-degree steps, straight steps and 180-degree steps, or at least steps including 90-step steps, straight steps, 90-degree steps, straight steps and 90-degree steps. Means a rough staircase structure.

  The dimensional information of staircase components includes the kick-up dimensions, tread dimensions, modules (meters / scales), wall thickness, surrounding stage first stage nose deviation dimension, circumference stage top stage nose deviation dimension, dimension from the top of the staircase to the wall surface, It is information such as landing stage tread dimensions, and particularly preferably includes a kick-up dimension, tread dimension, module (meter / scale), and wall thickness.

1-2. Step of determining handrail member combination conditions (step (2) above)
This step determines handrail member combination conditions necessary for construction based on the staircase pattern information. The combination condition of the handrail member is a condition such as a rough size, the number, and a rough processing shape (end portion angle) of the handrail member for constituting the handrail at the time of construction. For example, the staircase shown in FIG. 8 is a U-shaped staircase, which is composed of four lower straight steps, four steps 180 degrees clockwise (with a landing), and five upper straight steps. It is a stairs. Based on this staircase pattern information, for example, one long handrail member on the wall surface that continues to the four steps below, one short handrail member on the wall surface that continues to the landing, and two steps around the landing A medium-sized handrail member is required on the continuous wall surface, a short handrail member is required on the uppermost wall surface of the surrounding stage, and a long handrail member is required on the upper wall surface of the fourth level. The combination condition of the handrail member necessary for construction to be determined is determined. Moreover, you may determine the combination conditions of a member including the member (example: handrail member 60) for connecting a corner part continuously. When determining the combination conditions of handrail members, the combination conditions of handrail members corresponding to the order and the order of the direct steps / around steps / landings, the number of steps of the direct steps / around steps, etc., are shown in the correspondence table (for example “ It may be determined with reference to the table of “output logic”. The combination condition may be a condition of a rough length of the handrail member, or a classification condition such as various handrail members 30, 40, 50, 60 as shown in FIGS. There may be.

  At this time, for example, in the case of a handrail using the spacer 19 at the rear stage, the number of brackets and the shape necessary for construction, the number of screws, and the combination conditions of the accessory parts such as the shape and the number of the spacers 19 are determined. It is good as well.

  In this step, the combination conditions such as the rough size and number of handrail members or the combination conditions such as the number and shape of accessory parts are determined, but the detailed size and shape of the handrail member (the shape of the connection surface portion) , Angle, etc.) are not decided.

1-3. Handrail member shape determination step (step (3) above)
In this step, the shape of the handrail member is determined based on the dimension information of the staircase constituent member. For example, dimensional information of staircase components (lifting dimensions, tread dimensions, module (meter / scale), wall thickness, surrounding stage first stage nose deviation dimension, surrounding stage top stage nose deviation dimension, dimension from the top of the staircase to the wall surface, Based on information such as landing stage tread dimensions), the specific configuration of the handrail to be constructed on the stairs is determined, and the shape of the handrail member according to the configuration, for example, the size and shape of the handrail member (the shape of the connection surface portion, Angle etc.) is determined. In particular, in the case of the handrail member 10 shown in FIGS. 1 to 5, the length of the rod-like main body portion, the length of the inner surface 11 a, the presence / absence of the outer surface 11 b, the length, the angle, the angle of the connection surface portion 13 a, etc. The shape of the installation position of the screw hole 17, such as the installation position of the insertion hole 16, such as the length and angle of the outer plane portion 13 b, the installation position of the rod-shaped fixture 15, is determined by this step.

  Based on the data relating to the shape of the handrail member determined in this way, it is possible to create a drawing of the member (design drawing, drawing for processing device, drawing for construction, etc.) and output the created drawing. Is possible. It is also possible to transmit data related to the determined shape of the handrail member to the processing apparatus and perform processing based on the data. In addition, it is possible to create a wood plan for cutting out a plurality of handrail members from a long handrail member material, and further, a document related to manufacturing specifications such as a processing instruction sheet and a processing procedure manual. In addition, it is possible to create sales-related documents such as quotations and delivery notes.

  In addition, it is also possible to produce a drawing or jig for specifying the installation location of the handrail at the time of construction based on data on the shape of the handrail member. For example, a sheet in which the positional relationship between the stairs and the handrail constituent members (bracket, handrail member, etc.) is shown in actual dimensions can be considered. For example, it is easy to install a bracket at an accurate position by preparing a sheet that shows the actual relationship between the corners of the surrounding steps and the bracket, and affixing this sheet to the wall surface during stairs construction. It becomes.

  The shape determination method of the handrail member according to the present embodiment can be applied to various shapes as long as it is a pre-cut handrail member, and in particular, can be applied to the determination of the size of the handrail member having the following shape. it can.

1-4. Shape of Handrail Member As shown in FIG. 1, the handrail member 10 includes a rod-like main body portion 11 that extends in one direction (direction X in the drawing). The rod-shaped main body 11 may be made of a wood material, for example, a laminated material of natural wood or a solid material. 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 connection surface portions 12a and 13a at both end portions 12 and 13 thereof. However, the rod-shaped main body part 11 should just have the connection surface part 13a in the at least one edge part 13. As shown in FIG. The length of the rod-shaped main body part 11 can be changed according to conditions such as the length and position of the wall surface to be provided. A typical length is 50-5000 mm.

One connection surface portion 13 a is an inclined surface portion having a normal line A ₁ 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 the same inclined surface portion as the connecting surface portion 13a, but from the viewpoint of reducing the manufacturing cost due to the common use of parts and from the viewpoint of design, the shaft is it is preferably perpendicular surface portion composed of a plane perpendicular to the direction a _0.

  The connection surface portion 13 a configured by 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. In the example shown in the figure, the connection surface portion 13a has substantially the same contour shape as the other connection surface portion 12a. The substantially same outline shape is not limited as long as it is a shape that fits in the hand of a person, but is, for example, a rectangle. If it is such a shape, the shape of the other connection surface part 12a comprised by a perpendicular | vertical surface part can also be made into the rectangle of substantially the same outline shape. As a result, it becomes easy to make the connection surface portion 13a formed of the inclined surface portion substantially the same contour shape as the other connection surface portion 12a. In addition, you may equip each corner | angular part of a rectangle with the chamfering part. Typical dimensions when the contour shape is rectangular are 20 to 100 mm in length and 20 to 100 mm in width.

In particular, rod-shaped end portion 13 having the inclined surface 13a of the main body portion 11, a plane that constitutes the inclined surface 13a (plane having a normal A ₁₎ is, the inner side of the side surface which is inclined with respect to the axial direction A ₀ When the side surface 11a and the opposite side are the outer surface 11b, the inclined surface portion 13a is preferably provided between the surface including the inner surface 11a and the surface including the outer surface 11b. If it is this structure, the design property when constructing as a handrail will improve. As shown in FIG. 2, the other handrail member 10 has an end portion 13 provided with the inclined surface portion 13 a of the rod-shaped main body portion 11, an outer surface 11 b of the end portion 13, and a normal line A ₁ of the inclined surface 13 a. those comprising an outer flat portion 13b having a normal a ₂ having a substantially right angle. At this time, the inclined surface 13a and the outer flat surface portion 13b form a substantially perpendicular corner. 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 it is a substantially right angle, it is connected to a connection surface portion constituted by a vertical surface portion of another handrail member and constructed as a handrail. The design of the time is improved.

  Even if the handrail member 10 is a handrail having a bending point, the angle can be freely adjusted by precut processing, the number of members can be reduced, and the design is excellent. Therefore, the handrail member 10 is suitable for a handrail member for stairs, for example.

1-5. The handrail can be constructed (manufactured) by connecting the handrail member 10 and another handrail member and fixing it to the wall surface. The following are mentioned as another handrail member.

(1) An intermediate handrail member 30 having an inclined surface portion 31a at one end of the rod-shaped main body portion 31 and a vertical surface portion 31b at the other end shown in FIG. 3 (a) (an aspect of the handrail member of the present invention, symbol C in FIG. 8) ,
(2) As shown in FIG. 3 (b), a connecting surface portion having an inclined surface portion 41a at one end of the rod-shaped main body portion 41 and having a normal line perpendicular to the axis of the rod-shaped main body portion 41 at the other end. A handrail member 40 for start having 41c (an aspect of the handrail member of the present invention, symbol S in FIG. 8),
(3) As shown in FIG. 3 (c), a connecting surface portion 51c having a vertical surface portion 51b at one end of the rod-shaped main body portion 51 and having a normal line perpendicular to the axis of the rod-shaped main body portion 51 for fixing to the wall surface at the other end. An end handrail member 50 (reference numeral E in FIG. 8),
(4) As shown in FIG. 3 (d), a handrail member 60 having an inclined surface portion 61a at one end and a vertical surface portion 61b at the other end (one aspect of the handrail member of the present invention, symbol CS in FIG. 8),
(5) A handrail member (an aspect of the handrail member of the present invention, not shown) provided with inclined surface portions at both ends, and the like.

  In any handrail member, from the viewpoint of design, the contour shape of the cross section perpendicular to the axial direction in the length direction is substantially constant, and the contour shape of the cross section perpendicular to the axial direction of the handrail member 10 And substantially the same shape.

  As shown in FIG. 4, in the handrail, the connecting surface portion provided at at least one end portion of the handrail member 10 is provided with a rod-shaped fixture 15 protruding from the surface and having a large-diameter portion 15a at the tip. Yes. The connecting surface portion provided at at least one end of the other handrail member 100 has an insertion hole 16 for inserting the rod-shaped fixture 15, and a large-diameter portion 15 a of the rod-shaped fixture 15 at the bottom of the insertion hole 16. And a detachable grip 18. For example, when one handrail member 10 is connected to the other handrail member 100, the rod-shaped fixture 15 of one handrail member is inserted into the insertion hole 16 and fixed in that state.

  FIG. 5 illustrates this attachment / detachment mechanism. As shown in FIG. 5B, the grip 18 has a screw 18a that can be rotated by a driver. Then, when the rod-shaped fixture 15 is inserted into the insertion hole 16 and the screw 18a is rotated clockwise from the screw hole 17 formed in the vertical direction of the insertion hole 16, it is on the root side of the large-diameter portion 15a. It has a mechanism (so-called pulling mechanism) that engages with the neck portion 15b, pulls the large diameter portion 15a toward the bottom of the insertion hole 16 (right direction in the drawing), and grips it. In addition, when the grip portion 18 rotates the screw 18a counterclockwise, the grip portion 18 can release the engagement with the neck portion 15b, open the large diameter portion 15a, and remove other handrail members. Thereby, the handrail member 10 and the other handrail member 100 can be easily attached or detached.

  The connection between the handrail member 10 and the other handrail member 100 is most preferably performed by the above-described method. For example, in addition to a general method such as a method of fixing with a dowel, a method of fixing with a connection fitting and a screw, It is not necessary to fix these connecting surface portions simply by bringing them close to each other or bringing them into contact with each other. 5 shows an example in which the inclined surface portion is provided with the rod-shaped fixture 15 and the vertical surface portion is provided with the insertion hole 16 and the gripping portion 18. However, the inclined surface portion is provided with the insertion hole 16 and the gripping portion 18, and the vertical surface portion is disposed with the rod-shaped fixing tool 15. May be provided.

  A flat spacer 19 is preferably provided between the inclined surface portion and the vertical surface portion to be connected. Thereby, the shape difference and the gap between the connecting surface portions caused by the variation in processing accuracy are made inconspicuous, thereby contributing to the improvement of the design. Moreover, the contact damage at the time of connecting with another handrail member can also be reduced. Although there is no restriction | limiting in the material of the flat spacer 19, For example, they are a metal, hard resin, soft resin, etc.

  If the spacer 19 is too thin, the shape difference between the connecting surface portions becomes conspicuous and the design is deteriorated. Therefore, the thickness is preferably 1.0 mm or more. More preferably, it is 1.5 mm or more. On the other hand, if the thickness is too thick, the spacer 19 becomes conspicuous, and conversely, the design is deteriorated. Therefore, the thickness is preferably 3.0 mm or less. 2.5 mm or less is more preferable. When the spacer 19 is slightly larger than the connection surface portion, the spacer 19 becomes conspicuous and deteriorates the design. Therefore, the spacer 19 is configured to be smaller than the connection surface portion, that is, between the handrail member 10 and the other hand member 100. It is preferable that a groove is formed by the spacer 19. However, if the depth of the groove is too shallow, the shape difference between the connecting surface portions becomes conspicuous, and the design is deteriorated. Therefore, the depth is preferably 1.0 mm or more. More preferably, it is 1.5 mm or more. On the other hand, if the depth is too deep, it is easy for the user to hook or pinch the finger and the feeling of use deteriorates (especially when the spacer 19 is thick, the deterioration becomes significant), so the depth is 3.0 mm or less. To do. 2.5 mm or less is more preferable.

  As shown in FIG. 6, the handrail 200 is configured by connecting a handrail member 210 and another handrail member 220 formed of a rod-shaped main body portion extending in one direction. At this time, the inclined surface portion 213a of the handrail member 210 and at least one end portion of the other handrail member 220 are in contact with and fixed to the vertical surface portion 220a formed of a surface perpendicular to the axial direction. For this fixing, for example, the fixing method shown in FIG. 5 can be used.

  As shown in FIG. 6, construction may be performed so that the outer surface of the handrail member 210 faces downward in the vertical direction. However, as in the handrail 300 shown in FIG. You may turn to. In any case, it is preferable from the viewpoint of design that the outer side surface is provided with outer plane portions 213b and 313b.

  As shown in FIG. 8, when constructing the handrail on the outer wall of the staircase, for example, at the lowest position, the start handrail member S is provided along the ascending angle of the staircase. An intermediate handrail member C parallel to the dance scene is connected to the start handrail member S. In addition, the angle of the inclined surface part of the start handrail member S is set by the ascending angle of the stairs and is precut.

  And, in the staircase portion that further rises from the landing, when viewed from the vertical direction, a front wall (not shown) is constructed at a right angle to the first wall (not shown) on which the handrail member S for start is installed, The handrail is constructed on this wall surface. That is, the handrail member CS is provided in a direction parallel to the dance scene, and the intermediate handrail members C are sequentially connected along the upward 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 on this wall, the handrail member CS, the intermediate handrail member C, the intermediate handrail The member C and the end handrail member E are connected. After connecting a plurality of handrail members in advance, they may be attached to the wall surface via a bracket, or fixing to the wall surface and connection between the handrail members may be performed in parallel.

  Thus, since the handrail can be easily constructed and does not expose the connection surface, the design is extremely excellent.

2. Handrail member manufacturing method according to the present embodiment By determining the shape of the handrail member as described above, the handrail member can be manufactured. For example, a handrail member can be manufactured by the following steps (a) and (b) according to the determined shape.
(A) cutting at least one end of the rod-shaped material with a surface inclined with respect to the axial direction to form an inclined plane; and
(B) When the inclined plane is an outer surface opposite to the side inclined with respect to the axial direction, an outer plane portion is formed on the outer surface side by cutting along a plane orthogonal to the inclined plane. And a step of forming an inclined surface portion having substantially the same contour shape as the cross section perpendicular to the axial direction of the rod-shaped material.

  Thereby, it is possible to manufacture a handrail member only by a cutting process, without using special processes, such as shaving. In each of the above steps, a step of chamfering each corner may be provided. Moreover, you may further provide the process of coating the obtained handrail member.

3. Handrail manufacturing method according to this embodiment A handrail can be constructed using the handrail member manufactured as described above. At this time, the construction drawing created by the handrail member shape determination step (step (3) above) and the handrail installation jig (for example, the positional relationship between the corner portion of the surrounding step and the bracket are shown in actual dimensions. The bracket may be installed at an accurate position by preparing this sheet and sticking this sheet to the wall surface during the construction of the stairs.

  According to the present invention, the user can determine the combination condition and size (length, angle) of the handrail member appropriate for the stairs to be constructed simply by inputting the pattern of the stairs and the dimensions of the constituent members of the stairs. Since it can do, it is useful for manufacture of a pre-cut handrail member, and is also useful for manufacture of the handrail using the handrail member.
