<First Embodiment>
Hereinafter, the handrail device according to the first embodiment of the present invention will be described. As shown in FIGS. 1-3, the handrail apparatus 1 which concerns on this embodiment is a substantially H-type handrail structure 2, the horizontal shaft material 3, the wall surface pressing part 4, and the wall surface pressing means 5 (refer FIG. 3). Etc. In FIG. 1, the handrail device 1 is installed along one wall surface 30 of two opposing wall surfaces (the front wall surface is not shown in FIG. 1).

  The handrail structure 2 includes a plurality of columns 6, a handrail 7, a ceiling surface pressing unit 8 provided above each column 6, a floor surface pressing unit 10 provided below each column 6, and a horizontal member 9. The vertical collision tension generating means 11 and the like.

  In the example shown in FIG. 1, two pillars 6 are erected in parallel, and as shown in FIG. 2, female threads 20 for screwing bolts 13 described later are provided at the upper ends of the pillars 6. The column 6 includes a column main body 6a made of a cylindrical material such as a cylindrical material, a cover plate 6b disposed so as to close an upper end opening of the column main body 6a, a nut 21 and the like. A through hole 17 for inserting the bolt 13 is formed at the center of the cover plate 6b, and a nut 21 having the female screw 20 is welded to the lower surface of the cover plate 6b on the same axis as the through hole 17. . The lid plate 6b shown in FIG. 2 has an annular ridge 16 formed on the lower surface thereof fitted into the upper end opening of the column body 6a and welded to the column body 6a. Note that the lid plate 6, the bolts 13, and the like may be attached to the column body 6 a by simply omitting the welding between the lid plate 6 b and the column body 6 a and inserting the annular ridge 16 of the lid plate 6 b into the column body 6 a.

  Both ends of the handrail 7 are fixed to the two pillars 6 with screws or the like, respectively, and are thus constructed between the two pillars 6. The handrail 7 shown in FIG. 1 has a straight shape extending in the horizontal direction, but the shape, the installation direction, and the like are not limited to this as long as it functions as a handrail. For example, a curved or bent handrail may be installed between the two pillars 6, or this handrail or the straight handrail 7 may be installed between the pillars 6 in an oblique direction.

  As shown in FIG. 2, the ceiling surface pressing unit 8 includes a ceiling surface pressing plate 14, an anti-slip member 15, and the like.

  The ceiling surface pressing plate 14 presses the ceiling surface 25 via the anti-slip member 15 by the vertical collision tension generating means 11 described later. As the ceiling surface pressing plate 14, for example, a rectangular or circular flat plate can be used. It is desirable that the thickness of the ceiling surface pressing plate 14 is sufficient so that the pressing force applied to the ceiling surface 25 can be evenly distributed. Moreover, it is desirable to secure the area of the ceiling surface pressing plate 14 to such an extent that the pressure applied to the ceiling surface 25 can be sufficiently reduced.

  The anti-slip member 15 is interposed between the ceiling surface pressing plate 14 and the ceiling surface 25, and prevents the ceiling surface pressing plate 14 from sliding in the surface direction with respect to the ceiling surface 25. In addition, a material that is difficult to slip with respect to both the ceiling surface pressing plate 14 is employed. For the anti-slip member 15, for example, a resin material such as a sheet-like foamed resin can be employed. The anti-slip member 15 may be bonded to the ceiling surface pressing plate 14 with an adhesive or the like.

  As shown in FIG. 1, the floor pressing unit 10 includes a flat plate 26 fixed to the lower end of the column 6 by welding or the like, an anti-slip member 15, and the like. It is desirable that the thickness of the flat plate 6 is sufficient so that the pressing force applied to the floor surface 27 can be evenly distributed. Moreover, it is desirable to ensure the area of the flat plate 26 to such an extent that the pressure applied to the floor surface 27 can be sufficiently reduced. The anti-slip member 15 is interposed between the flat plate 26 and the floor surface 27, and prevents the lower surface of the flat plate 26 from sliding in the surface direction with respect to the floor surface 27. As the anti-slip member 15, the same one as described above that is interposed between the ceiling surface pressing plate 14 and the ceiling surface 25 can be used. Note that the lower end of the column 6 and the flat plate 26 may not be fixed by welding or the like but may be inserted. In order to be a plug-in type, for example, a solid column, a hollow column or the like having a shape that can be fitted into the column 6 (if the column 6 is a cylinder, a solid corresponding to the inner diameter size) A cylindrical body or a hollow cylindrical body) is erected on the flat plate 26, and this column body is inserted through the lower end opening of the column 6 and attached.

  The horizontal member 9 is installed between the two pillars 6 to strengthen the connection between the two pillars 6 and increase the structural rigidity of the handrail structure 2. As the horizontal member 9, for example, a solid bar as shown in FIGS. 3 and 4 can be used. In the present embodiment, the horizontal member 9 passes through the two columns 6 in the horizontal direction and is pressed against the tip of a bolt 6d that is screwed into a female screw 6c (see FIG. 3) formed in the column 6. This is fixed to the pillar 6.

  The longitudinal collision tension generating means 11 is for causing the column 6, the ceiling surface pressing unit 8 and the floor surface pressing unit 10 to generate a projecting tension with respect to the ceiling surface 25 and the floor surface 27. In this embodiment, as shown in FIG. 2, the vertical collision tension generating means 11 is screwed into the female screw 20 provided on the top of the column 6 and the female screw 20 with its axial direction being up and down. And the bolt 13 to which the ceiling surface pressing plate 14 is connected.

  The upper end of the bolt 13 is connected to the ceiling surface pressing plate 14 so as to be relatively rotatable. In order to realize such a connection, the nut portion 22a of the nut 22 with a washer is welded to the upper end of the bolt 13 so as not to be relatively rotatable, and the washer portion 22b of the nut 22 with a washer is welded to the lower surface of the ceiling surface pressing plate 14. ing. The nut with washer 22 is such that the inner peripheral portion of the washer portion 22b is fitted in an annular recess 23 formed around the seat surface of the nut portion 22a so as to be relatively rotatable, and is engaged with each other in the axial direction. Further, since a gap is secured between the lower surface of the ceiling surface pressing plate 14 and the nut portion 22 a, the nut portion 22 a is rotatable relative to the ceiling surface pressing plate 14. Reference numeral 24 denotes a tightening nut screwed to the bolt 13. By tightening the tightening nut 24 toward the cover plate 6b, the bolt 13 is fixed so as not to rotate with respect to the cover plate 6b (column 6).

  When the bolt 13 is turned so that the ceiling surface pressing portion 8 (ceiling surface pressing plate 14 or the like) moves upward with respect to the column 6, the ceiling surface pressing portion 8 presses the ceiling surface 25, and this A vertical tension is generated in the ceiling surface pressing portion 8, the pillar 6, and the floor surface pressing portion 10. Thereby, the column 6 is fixed between the ceiling surface 25 and the floor surface 27, and as a result, the position of the handrail 7 installed between the two columns 6 is also fixed.

  As shown in FIGS. 3 and 4, the horizontal shaft member 3 extends laterally from the column 6 and is disposed substantially perpendicular to the wall surface 30. The horizontal shaft member 3 is composed of a cylindrical member 31, a nut 34 with a washer, a bolt 33, and the like.

  The cylindrical member 31 passes through the column 6 in a direction substantially perpendicular to the wall surface 30, and is pressed in the axial direction by being pressed by the tip of a bolt 6 d screwed to a female screw 6 c formed on the column 6. It is fixed to the column 6 so that it cannot move.

  The nut 34 with a washer is the same as the nut 22 with a washer described above connected to the ceiling surface pressing plate 14. As shown in the partially enlarged view of FIG. 3, the nut 34 with the washer has a nut portion 34 a screwed to the bolt 33 and a washer portion 34 b seated on the end of the tubular member 31. The axial position of the bolt 33 can be adjusted by turning the nut portion 34a.

  One end of the bolt 33 is connected to the wall pressing portion 4 so as to be relatively rotatable. This connection is the same as the connection between the ceiling surface pressing plate 14 and the bolt 13. That is, as shown in the partial enlarged view in FIG. 3, the nut portion 22 a of the nut with washer 22 is welded to one end of the bolt 33 so as not to be relatively rotatable, and the washer portion 22 b of the nut with washer 22 is attached to the wall pressing plate 28. It welds to one side (surface on the opposite side to the wall surface 30).

  The wall pressing portion 4 is pressed against the wall 30 by the wall pressing means 5 described later. The wall pressing portion 4 includes a wall pressing plate 28, an anti-slip member 15 and the like. As the wall pressing plate 28, the same one as the ceiling pressing plate 14 described above can be adopted. The shape of the wall pressing plate 28 is not particularly limited, but it is desirable that the wall pressing plate 28 has a sufficient thickness so that the pressing force applied to the wall 30 can be evenly distributed when the wall 30 is pressed. Moreover, it is desirable to secure the area of the wall surface pressing plate 28 to such an extent that the pressure applied to the wall surface 30 can be sufficiently reduced. As the non-slip member 15, the same anti-slip member 15 interposed between the ceiling surface pressing plate 14 and the ceiling surface 25 can be adopted.

  The wall surface pressing means 5 is for pressing the wall surface pressing portion 4 against the wall surface 30 after the column 6 or the like is fixed between the ceiling surface 25 and the floor surface 27. The nut 34 with a washer disposed at the end of the member 31 and the bolt 33 screwed to the nut portion 34a of the nut 34 with this washer with the axial direction orthogonal to the wall surface 30 are mainly used. It is configured. In this embodiment, the wall pressing means 5 is constituted by a nut 34 with a washer, a bolt 33, and the like. However, instead of the nut 34 with a washer, the above-described cover plate 6b, nut 21, and tightening nut 24 are provided. The structure which consists of etc. may be employ | adopted. That is, even with this configuration, it is possible to press the wall pressing portion 4 provided at the end of the bolt 33 against the wall 30.

  In installing the handrail device 1 having the above-described configuration between the ceiling surface 25 and the floor surface 27, first, the tightening nut 24 shown in FIG. It is turned using a tool or the like to adjust the height of the upper surface of the ceiling surface pressing portion 8 to be lower than the ceiling surface 25. Further, the wall pressing portion 4 is sufficiently brought close to the column 6 side by turning the nut portion 34a of the nut 34 with washer, the nut portion 22a of the nut 22 with washer and the like shown in FIG.

  Next, the handrail structure 2 including the pillar 6, the handrail 7, the ceiling surface pressing unit 8, the floor surface pressing unit 10 and the like is disposed at a desired position between the ceiling 25 and the floor 27, and the washer shown in FIG. While rotating the nut portion 22a of the attached nut 22 with a tool, the ceiling surface pressing portion 8 is raised and pressed against the ceiling surface 25 with a predetermined pressing force. Then, the tightening nut 24 is tightened to fix the bolt 13 so as not to rotate with respect to the column 6. As a result, a ceiling tension with respect to the ceiling surface 25 and the floor surface 27 is generated in the ceiling surface pressing portion 8, the column 6, the floor surface pressing portion 10, etc., and these are fixed between the ceiling surface 25 and the floor surface 27. The As a result, the position of the handrail 7 installed between the two pillars 6 is also fixed.

  Thereafter, the wall pressing portion 4 is moved to the wall surface 30 side while the nut portion 34a of the nut 34 with washer and the nut portion 22a of the nut 22 with washer shown in FIG. Hit it. The pressing force when pressing the wall pressing portion 4 against the wall surface 30 side may be a minute force such that the wall pressing portion 4 is in contact with the wall surface 30.

  By performing the above procedure, the handrail device 1 is installed between the ceiling surface 25 and the floor surface 27 as shown in FIG. In this handrail device 1, even when a force toward the horizontal wall surface 30 is applied to the handrail 7 when the handrail 7 is gripped, the force is applied to the horizontal shaft member provided between the wall surface 30 and the handrail structure 2. 3 and the wall pressing part 4, the handrail device (handrail 7) is less likely to wobble in the horizontal direction and is difficult to move. The force toward the horizontal wall surface 30 includes a horizontal component force such as a force acting obliquely downward toward the wall surface 3 and a force acting obliquely upward on the handrail 7.

  In the embodiment described above, the horizontal shaft member 3 and the wall pressing portion 4 are provided at the upper part of the column 6, but these are provided at other positions such as the lower part of the column 6 and the middle part of the column 6. It may be. Further, in the above-described embodiment, one wall pressing part 4 and the horizontal shaft member 3 are attached to one column 6, but a plurality of wall pressing parts 4, A horizontal shaft member 3 may be attached.

  In the embodiment described above, the horizontal shaft member 3 and the wall pressing portion 4 are provided on all the columns 6 (two columns 6 in the example of FIG. 1). This section 4 does not necessarily have to be provided on all pillars 6.

  In the above-described embodiment, the ceiling surface pressing portion 8 is movable to the column 6 by the bolt 13 or the like so as to be movable in the vertical direction. The projecting tension may be generated by allowing the portion 10 to move in the vertical direction with a bolt or the like. Alternatively, both the ceiling surface pressing unit 8 and the floor surface pressing unit 10 may be moved in the vertical direction with bolts or the like with respect to the column 6 so as to generate a thrust.

<Second Embodiment>
Next, a handrail device according to a second embodiment of the present invention will be described. Below, about the structure similar to the handrail apparatus 1 which concerns on 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted, and the difference with the handrail apparatus 1 which concerns on 1st Embodiment is mainly shown. explain.

  As shown in FIGS. 5 and 6, the handrail device 1A according to the present embodiment is the handrail device 1 according to the first embodiment in which the horizontal shaft member 3 extends to both sides of the pillar 6 (hereinafter referred to as “railway device”). One of them is arranged across a passage 36 formed between two opposing wall surfaces 30 (the front wall surface is not shown in FIG. 5). It has become.

  For example, as shown in FIG. 6, the horizontal shaft member 3 </ b> A extends the tubular member 31 in the first embodiment, and is similarly provided with a nut 34 with a washer, a bolt 33, and the like at both ends of the tubular member 31. Furthermore, the wall surface pressing portion 4 is connected to the tip portions of both bolts 33 via nuts with washers 22 so as to be relatively rotatable. Although the height position of the horizontal shaft member 3A (particularly the cylindrical member 31) is not limited, the horizontal shaft member 3A crosses the passage 36, and therefore does not hinder the passage of ordinary people. It is desirable to arrange at a position as high as possible.

  In the handrail device 1A according to the present embodiment, the nut portions 22a welded to the tips of the bolts 33 on both sides or the nut portions 34a of the nuts 34 with washers disposed at both ends of the cylindrical member 31 are used with a tool. By rotating the wall pressing portion 4 from the cylindrical member 31 to the wall surface 30 side, for example, the lateral shaft member 3A and both wall pressing portions 4 can generate a thrust on the two wall surfaces 30. . As a result, the handrail device 1A according to the present embodiment is less likely to wobble and move even when a force toward the front side in the horizontal direction is applied to the handrail 7.

  In this embodiment, as shown in FIG. 6, wall pressing means 5 (bolts 33, nuts with washers 34, etc.) are provided on both sides of the horizontal shaft member 3 </ b> A. May be omitted. Further, in this embodiment, the wall pressing means 5 is constituted by the bolt 33, the nut 34 with a washer, etc., but instead of the nut 34 with a washer, the cover plate 6b and the nut 21 described in the first embodiment. Alternatively, a configuration including the tightening nut 24 and the like may be employed.

<Third Embodiment>
Next, a handrail device according to a third embodiment of the present invention will be described. In the following description, the same components as those of the handrail device 1A according to the second embodiment are denoted by the same reference numerals, and the description thereof is omitted. Differences from the handrail device 1A according to the second embodiment are mainly described. To do.

  As shown in FIG. 7 and FIG. 8, the handrail device 1B according to the present embodiment includes two opposing wall surfaces 30 (the front side in FIG. 7) in the handrail device 1A according to the second embodiment (see FIG. 5). The handrail structure 2 is installed along both of the wall surfaces (not shown). The horizontal shaft member 3 </ b> A is disposed across the passage 36, and is attached to two pillars 6 disposed across the passage 36 so as to penetrate both sides thereof. The mounting structure (fixed by bolts 6d) of the horizontal shaft member 3A to the two columns 6 arranged with the passage 36 interposed therebetween is the same as that described with reference to FIG. 4 in the first embodiment.

  In the handrail device 1B according to the present embodiment, a floor surface pressing portion 10A different from the floor surface pressing portion 10 of the handrail device 1A according to the second embodiment is employed. This floor surface pressing portion 10A is constructed at the lower end portions of the two pillars 6 arranged with the passage 36 therebetween, and for example, as shown in FIG. The floor pressing plate 38 and the anti-slip member 39 are interposed between the two.

  The floor pressing plate 38 is a flat plate that is rectangular in plan view and is bent into a cross-sectional mountain shape in order to increase buckling strength, bending rigidity, and the like, and a screw insertion slit 38a is formed in the longitudinal direction at the top of the mountain shape. It is formed in the direction crossing the passage 36. A screw 40 is inserted into the slit 38a of the floor pressing plate 38 from the bottom to the top, and the male screw portion thereof is screwed into a female screw included in a screw mounting portion 6e provided inside the column 6, so that the floor surface The pressing plate 38 is fastened to the lower end of the column 6.

  Further, as shown in FIGS. 9 to 11, the floor pressing plate 38 has an inclination from both sides toward the slit 38 a that is further increased in the vicinity of the slit 38 a to form a column engaging convex portion 38 b. . As shown in FIG. 12, the pillar engaging convex portion 38 b has a shape that fits into the floor surface pressing plate engaging concave portion 6 f formed at the lower end of the pillar 6. Thereby, when the floor surface pressing plate 38 is fastened to the lower end of the column 6 with the screw 40, the circumferential position of the floor surface pressing plate 38 and the column 6 is automatically determined, and various screw holes provided in the column 6 are attached. The holes are naturally arranged at desired positions, and the efficiency of the assembly work is improved.

  In addition, in order to make it easy to adjust the distance between the columns 6 arranged across the passage 36, the slit 38a is employed as an insertion hole for the screw 40 with respect to the floor pressing plate 38, but the above adjustment is unnecessary. May adopt a circular hole instead of the slit 38a. Further, the lower end of the pillar 6 and the floor pressing plate 38 may not be completely fixed but may be of a plug-in type. In order to be a plug-in type, for example, a solid column, a hollow column or the like having a predetermined height that can be fitted into the column 6 on the upper surface of the floor pressing plate 38 (in the case where the column 6 is a cylinder, the inner diameter size thereof) May be fastened on the floor pressing plate 38 with screws 40, and the column body may be inserted into the lower end opening of the column 6 and attached.
