  Further, in the above-described conventional handrail support column, the screwing portion between the base member and the column main body member is hidden by the cover, but it is also possible to prevent the appearance from being impaired without using such other members. It is included in the object of the present invention.

  In order to achieve the above object, the handrail support column according to the present invention has a column main body member that is open at the top and has a column main body mounting opening on a side thereof, and a column main body member from the column main body mounting opening. The base portion of the handrail is inserted and fitted to be assembled, and an outer portion of the base portion of the column main body member is formed with an engaging portion that engages with the base member in the recess. An engagement receiving portion that engages with the engagement portion is formed on the inner side of the recess of the member, and the engagement between the engagement portion and the engagement reception portion is in the longitudinal direction with respect to the mounting surface. It is made by the concave and convex fitting by the concave groove and the convex portion formed substantially in parallel, and is configured to prohibit the column main body member from coming out upward, and the outer side of the base portion of the column main body member and the recess of the base member Each inner part is provided with a stopper mounting part for fixing the stopper in the vertical direction with respect to the mounting surface. And wherein the Rukoto.

  Moreover, in this invention, the fastener attachment part of a base member is formed in the position which can be planarly viewed in the state in which the base part of the column main body member is not inserted in the recess.

  Furthermore, in the present invention, the fastener mounting portion of the base member includes a recess that accommodates the head of the fastener.

  Furthermore, in the present invention, the base member has a structure having a lower end opening communicating with the recess, and the engaging portion of the column main body member and the engaging receiving portion of the base member are substantially the same height from the lower end surface of each member. Arranged in position.

  According to the handrail support column according to the present invention, the structure as described above can prevent the column main body member from being pulled out upward by the engagement between the engagement portion and the engagement receiving portion. The connection fixing property between the base member and the column main body member can be improved without using any tools. Further, since the use of the fastener can be reduced, the assembly and fixing work of the handrail support can be quickly performed.

  Further, with the above-described configuration, even if the attachment portion of the stopper for assembling and fixing the handrail support column is not covered with a cover or the like, it is hardly exposed to the outside.

FIG.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 5 is a perspective view showing an example of a handrail to which the handrail support of the present invention is applied. In the illustrated example of the present embodiment, the handrail is an open-type staircase with the living room or hallway open, but any handrail that can be supported by a plurality of handrail struts may be used. Such various handrails for handrails are the subject of the present invention.

  1-4 is explanatory drawing of the support | pillar for handrails used for the handrail of the open type staircase shown in FIG. In addition, in the example of FIG. 5, although the main pillar and the child pillar are used as the handrail support | pillar 1, the handrail support | pillar of this invention is applicable to both. These handrail support pillars 1, 1,... Are attached to an attachment surface 2 such as a floor or a step board of a staircase.

  The handrail support column 1 includes a base member 10 that is fixedly attached to the mounting surface 2 of the stair tread, and a column body member 20 that is attached to the base member 10 and fixed to the mounting surface 2. .

  The base member 10 has an upper end opening 12a and a lower end opening 12b, a side column body mounting opening 12c, and a recess 11 that communicates with these openings. Three concave grooves 14, 14, 14 extending substantially parallel to the lower end surface are formed on the inner side of the recess 11 and extend over three inner walls (left inner wall, inner wall, right inner wall).

  The recess 11 is a recess for fitting and mounting a base portion 21 of a column main body member 20 to be described later, and the concave groove 14 is engaged with an engagement portion (convex portion) of the column main body member 20. Any groove may be used as long as it constitutes the receiving portion and the column main body member 20 does not come out upward due to their engagement. In addition, as for a convex part, it is desirable to make it the protruding item | line 22 like the example of a figure.

  In any of the three wall portions 13, 13, and 13 (the left wall, the back wall, and the right wall), the lower wall portion 13b of the recessed groove 14 is located more inward of the recess 11 than the upper wall portion 13a. It protrudes and is formed thick. That is, the concave groove 14 is formed such that the lower groove wall surface 14b is larger in size than the upper groove wall surface 14a.

  A plurality of screw insertion holes leading to the lower end of the base member 10 are formed at positions that can be seen from above the lower groove wall surface 14 b of the concave groove 14. This screw insertion hole constitutes a mounting hole 15 (fastener mounting portion) of a screw 3 (fastener) for fixing the base member 20 to the mounting surface 2. The mounting hole 15 is preferably provided in any of the three wall portions 13, 13, 13, but may be provided in a location corresponding to only the two wall portions 13, 13. Further, as will be described later, the column main body member 20 that is fitted and connected to the base member 10 is also screwed to the mounting surface 2. A configuration may be adopted in which the screw 3 is attached only to the lower groove wall surface 14b of the groove 14 on the wall side. In addition, it is desirable that the attachment holes 15 are opened at a plurality of locations with respect to the respective concave grooves 14.

  Further, the stopper for mounting and fixing the base member 10 is not limited to the screw 3, and other stoppers such as a nail may be used. Moreover, the attachment hole 15 does not need to be provided, and at least a stopper attachment portion to which the stopper is attached in the vertical direction is formed at the inner side of the recess 14. In other words, the stopper mounting portion may be a portion that can fix the stopper to the lower mounting surface 2 from above, like the lower groove wall surface 14b of the concave groove 14 shown in the drawing.

  In addition, it is desirable to provide the stopper mounting portion at a position where it can be seen from vertically above, but it may be visible from above obliquely. For example, the upper wall portion and the lower wall portion of the concave groove 14 may be formed to have the same wall thickness so that the lower groove wall surface 14b of the concave groove 14 cannot be viewed in a plan view. You may make it hit diagonally.

  The mounting hole 15 in this example is formed substantially perpendicular to the mounting surface 2 (the lower end surface of the base member 20), but may be formed to be inclined. In particular, in order to more firmly fix the base member 20 to the mounting surface 2, an inclined hole that can be screwed in mutually different inclination directions may be used.

  Further, as shown in the enlarged sectional view of FIG. 1, the upper end portion of the mounting hole 15 has a diameter enough to accommodate the entire screw head 3 a rather than the insertion hole 15 b through which the shaft portion 3 b of the screw 3 is inserted. A large recess 15a is formed. By providing such a recess 15a, when the screw 3 is fixed to the mounting hole 15, the screw head 3a is submerged in the recess 15a so that the screw 3 does not protrude above the lower groove wall surface 14b. .

  On the other hand, the column main body member 20 includes a base portion 21 mounted in the recess 11 of the base member 10 and a prismatic columnar body 24 that stands upright above the base portion 21. The base portion 21 and the column body 24 may be integrally formed, or may be integrated by combining separate bodies. Further, the column body 24 is not limited to a rectangular column, and may be another columnar body such as a cylinder or a deformed column.

  The column main body member 20 can be slidably mounted in the recess 11 of the base member 10 from the lateral (substantially horizontal) direction. A protrusion 22 (engagement portion) that is fitted to the receiving portion) with almost no gap is formed.

  The base 21 of the column main body member 20 has an outer shape that fits so that not only the ridges 22 but also the outer side contacts the inner side of the recess 11 of the base member 10, as shown in FIG. When assembled, the base 21 is interconnected to the recess 11 without a gap. Moreover, the height position from the lower end surface of the base 21 of the ridge 22 is substantially the same as the height position from the lower end surface of the base member 10 of the concave groove 14, and the column main body member 20 and the base member 10 are connected. In this case, the lower end surfaces of both members 20 and 10 are substantially flush.

  In addition, the upper end surface of the outer portion of the base portion 21 has an opening of the mounting hole 23 for the screw 3 for fixing the column main body member 20 to the mounting surface 2 on the near side of the column body 24, which leads from the upper end surface to the lower end surface. Is provided. The attachment holes 23 may be provided at one place as shown in the figure, but may be provided at a plurality of places. For example, it may be screwed in the back space.

  In addition, it is desirable to provide the mounting hole 23 of the column main body member 20 also with the recessed part which does not protrude the screw head 3a.

  Further, the fastener is not limited to the screw 3, and may be other fasteners such as a nail, the attachment hole 23 may not be provided, and a portion (fastener attachment portion) where the fastener can be attached in the vertical direction at least. What is necessary is just to be formed in the outer side part.

  The handrail support 1 composed of such two members is assembled by the following procedure and fixed to the mounting surface 2.

  First, the base member 10 is placed at a predetermined position on the mounting surface 2 and screwed in the plurality of mounting holes 15, 15 of the recess 11.

  Next, the base 21 is fitted and mounted in the recess 11 while sliding the column main body member 20 toward the column main body mounting opening 12 c of the base member 10 while being mounted on the mounting surface 2.

  After the column body member 20 is mounted and connected to the base member 10, the column body member 20 is screwed to the mounting surface 2 in the mounting hole 23.

  Thus, the base member 10 and the column main body member 20 are fitted and connected to each other by the engagement of the concave grooves 14 and the convex strips 22, and the respective members 10 and 20 are individually fixed to the mounting surface 2. Both members 10 and 20 are connected and fixed to each other.

  According to such a handrail support 1, the base member 10 is fixed to the mounting surface 2 by screwing the inner portion of the recess 11. The base 21 of the column main body member 20 is formed in the recess 11. Since it is attached, screwing portions such as the screw head 3a are not exposed to the outside. Further, since it is not necessary to hide the screwing portion with other members, the handrail support column 1 can be composed of the base member 10 and the column main body member 20. Therefore, cost reduction and simple assembly can be realized.

  Further, the concave groove 14 and the ridge 22 are structured so that their longitudinal directions are substantially parallel to the mounting surface 2 and are engaged so as to prevent the column main body member 20 from being pulled out upward. . In other words, the fitting and fixing of both the members 10 and 20 can improve the connecting and fixing properties of both the members 10 and 20 without screwing. That is, in order to securely connect and fix the base member 10 and the column main body member 20, the column main body member 20 is pulled out in the lateral direction at the mounting holes 23 (fastener mounting portions). You just need to screw it to prevent it. As described above, since the number of screwing points can be reduced, the assembly and fixing work can be performed quickly.

  Moreover, although the stopper attachment part of the base member 10 is formed in the recess 11, since it exists in the position which can be visually recognized from upper direction, it can work from upper direction and there is almost no difficulty on work. In particular, as in the example of the present embodiment, if the stopper mounting portion is provided at a position where it can be visually recognized from above (that can be seen in plan view), it can be operated from directly above, and the assembly work can be facilitated.

  Further, since the recessed portion 15a is formed in the mounting hole 15 of the base member 20, the screw head 3a of the mounted screw 3 does not protrude, and the protrusion 22 of the column body member 20 is engaged with the recessed groove 14 without a gap. Can be combined. In addition, although it is desirable to provide the recessed part 15a in the attachment hole 15, it is not necessary to provide it, and in that case, the recessed groove 14 should be formed wider than the ridge 22 so that the protruding space of the screw head 3a is formed. Is desirable.

  In addition, the base member 10 of the present embodiment has a lower end opening 12b that communicates with the recess 11 and the concave groove 14 is formed at the same height as the ridge 22 of the column main body member 20. The lower end surface can be mounted while being slid with the mounting surface 2 mounted. Thus, it is not necessary to align both members 10 and 20 in the vertical direction, and it is not necessary to lift and mount the column main body member 20, so that the assembly work can be performed easily.

  Moreover, although the lower end opening 12b is provided in the base member 10 of the handrail support column 1 of the present embodiment, as shown in another embodiment of FIG. 6, it has a structure having a bottom portion 16 having no opening. There may be.

  According to the base member 10 having such a bottomed structure, the base member 10 can be configured more robustly. Moreover, since both the members 10 and 20 can also be connected by screwing to the attachment surface 2 in the attachment hole 23 of the column main body member 20, the connection fixation property of both the members 10 and 20 is improved further.

  In the embodiment shown in FIG. 6, the same components as those in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted.

  In the above embodiment, the example in which the ridge 22 is engaged with the concave groove 14 has been shown (see FIG. 1 and the like). However, as the convex portion that constitutes the engaging portion of the column main body member 20, Instead, a plurality of intermittent protrusions that fit into the groove 14 may be provided.

  Next, a handrail support according to still another embodiment of the present invention will be described with reference to FIGS.

  In this embodiment, each of the engagement receiving portion on the inner side of the recess 11 provided on the base member 10 and the engagement portion on the outer side of the base portion 21 of the column main body member 20 are fitted to each other on the mounting surface. The substantially parallel concave and convex grooves and ridges are formed of concave and convex surfaces 14A and 22A that are regularly continuous up and down.

  Since the concave and convex surfaces 14A and 22A are engaged with each other in this way, the base 21 of the column main body member 20 may be mounted in the recess 11 without a gap as shown in FIG. As shown in FIG. 7C, the base 21 may be shifted upward and mounted in the recess 11. That is, the height of the handrail can be varied using the same member, and the height can be easily adjusted.
