The strut and the horizontal member have a curved outer peripheral surface (for example, an outer peripheral surface 66a described later), and the outer peripheral surfaces of the column and the horizontal member are flush with each other without forming a step with the outer peripheral surface of the joint cover. It may be continuous through the cover.

The support column has flat left and right side surfaces (for example, left and right side surfaces 2b described later), and the horizontal member has flat left and right side surfaces (for example, left and right side surfaces 5b described later). The joint cover has flat left and right side surfaces (for example, left and right side surfaces 66b described later), and the left and right side surfaces of the support column and the horizontal member are stepped from the left and right side surfaces of the joint cover. May be continuous via the joint cover so as not to occur.

The support column has a flat inner peripheral surface (for example, an inner peripheral surface 2c described later), and the horizontal member has a flat inner peripheral surface (for example, an inner peripheral surface 5c described later). The joint base has a curved inner peripheral surface (for example, an inner peripheral surface 63b described later), and the inner peripheral surfaces of the support column and the horizontal member are stepped from the inner peripheral surface of the joint base. May be continuous via the joint base so as to be flush with each other.

The horizontal member may be provided with the inner peripheral surface cover over the entire length of the horizontal member main body.

By screwing into the female screw portion 65a of 56, the mounting bracket 7 is fixed to the central portion of the cap tree 5.

Then, as shown in FIG. 1, in a state where the cap tree 5 is hung on the upper side of the pair of left and right end columns 2 and the intermediate column 3 and connected by the joint 6 and the mounting bracket 7, the end column 2 and the cap tree 5 are connected. 2a and 5a are flush with the outer peripheral surface 66a of the joint cover 62, and the left and right side surfaces 2b and 5b are stepped with the left and right side surfaces 66b of the joint cover 62. It is continuous without being flush with the joint cover 62, and the inner peripheral surfaces 2c and 5c are flush with the inner peripheral surface 63b of the joint base 61 via the joint base 61. It is continuous. Therefore, the handrail 1 is integrally connected even though the pair of left and right end pillars 2 and the three members of the Kasagi 5 are actually connected in an inverted U shape via the two joints 6. Since it looks like it is, the design is improved.

Since the handrail 1 has the above-described configuration, when assembling the handrail 1 during construction of the handrail 1, as described below, an intermediate pillar mounting process and an end pillar mounting process (first joint base fixing step) , The second joint base fixing process and the joint cover fixing process), and the inner peripheral surface cover mounting process are carried out in this order.

First, in the intermediate pillar attaching step, the intermediate pillar 3 is attached to the lower side of the central portion of the Kasagi 5. To do so, as shown in FIG. 5A, a mounting bracket 7 is placed on the upper side of the intermediate pillar 3, and in this state, two tapping screw insertion holes 71a of the mounting bracket 7 are placed from above. The mounting bracket 7 is fixed to the upper end of the intermediate pillar 3 by inserting the tapping screw 15 and screwing it into the screwed portion 32 of the intermediate pillar 3. On the other hand, as shown in FIG. 5B, the back plate 56 is inserted into the back plate fitting groove 52 of the cap tree 5 from the side and positioned at the center of the back plate fitting groove 52, whereby the center of the cap tree 5 is formed. The back plate 56 is attached to the portion. In this state, as shown in FIG. 5C, the two screws 16 are inserted into the two screw insertion holes 71b of the mounting bracket 7 from below the central portion of the cap tree 5 and into the female screw portion 65a of the back plate 56. By screwing in, the mounting bracket 7 is fixed to the central portion of the cap tree 5. Then, the intermediate pillar 3 is attached to the lower side of the central portion of the Kasagi 5. At this point, the intermediate column mounting process ends.

Next, the process shifts to the end pillar mounting process, the first joint base fixing step (the first step of the end pillar mounting process), and as shown in FIG. 4A, the upper end of each end pillar 2 The joint base 61 is fixed to each portion with two tapping screws 11. To do so, the joint base 61 is placed on the upper side of the end pillar 2, and in this state, the tappin screw 11 is inserted into the tappin screw insertion hole 63c of the joint base 61 from above to screw the end pillar 2. Screw into the portion 22.

After that, the process proceeds to the second joint base fixing step (the second step of the end pillar mounting step), and as shown in FIG. 4 (b), two hexagons of these joint bases 61 are attached to both ends of the Kasagi 5. Fix with bolt 12. To do so, the cap tree insertion portion 65 of the joint base 61 is inserted into the end portion of the cap tree 5, and in this state, the hexagon bolt 12 is inserted from below the end portion of the cap tree 5 into the bolt insertion hole 53 of the cap tree 5 to insert the cap tree. It is screwed into the female screw portion 65a of the portion 65.

Next, the process proceeds to the joint cover fixing step (the third step of the end column mounting step), and the joint cover 62 is fixed to each joint base 61 with two hexagon bolts 13 in a state of covering the joint base 61. .. To do so, as shown in FIG. 4 (c), the Kasagi insertion piece 67 of the joint cover 62 is inserted into the end of the Kasagi 5, and in this state, as shown in FIG. 4 (d), the hexagon bolt 13 is inserted into the Kasagi. From below the end of 5, the round hole 55 of the cap tree 5 and the bolt insertion hole 65b of the joint base 61 are sequentially inserted and screwed into the female thread portion 67a of the joint cover 62. At this point, the end pillar mounting process ends.

Finally, the process shifts to the inner peripheral surface cover mounting process, and as shown in FIGS. 4 (e) and 5 (d), the inner peripheral surface cover 59 is attached to the inner peripheral surface of the Kasagi main body 51 of the Kasagi 5 with hexagon bolts 12. 13. Attach the mounting bracket 7 and the screw 16 so as to cover them. To do so, the pair of engaging pieces 592 of the inner peripheral surface cover 59 are engaged with the pair of cover engaging grooves 57 of the Kasagi 5. At this time, the inner peripheral surface cover 59 is attached over the entire length of the Kasagi main body 51 except for the portion that interferes with the intermediate pillar 3. At this point, the process of attaching the inner peripheral surface cover is completed.

As a result, as shown in FIGS. 1 to 3, the handrail 1 has a pair of end pillars 2 arranged at both ends thereof, and an end connecting portion (each end pillar 2 and a cap tree 5). The joint base 61 is covered with the joint cover 62, the hexagon bolts 12 and 13 are covered with the inner peripheral surface cover 59, and the central connecting part (intermediate pillar 3 and Kasagi 5). The mounting bracket 7 and the screw 16 are covered with the inner peripheral surface cover 59 in a noiseless state, and the assembly work of the handrail 1 is completed here.

Here, the assembly work was carried out in the order of the intermediate pillar mounting process and the end pillar mounting process, but if a notch is provided at the end of the Kasagi 5 and the back plate 56 is passed through, these steps can be performed. It is also possible to reverse the order and proceed with the assembly work in the order of the end pillar mounting process and the intermediate pillar mounting process. It is also possible to attach one end pillar 2 to the cap tree 5, then attach the intermediate pillar 3 to the cap tree 5, and then attach the other end pillar 2 to the cap tree 5. Further, in the end column mounting step, the order of the first joint base fixing step and the second joint base fixing step may be reversed.

In such a handrail 1, since the joint base 61 is covered with the joint cover 62 in the state after assembly, the design of the handrail 1 can be improved by making the joint 6 noiseless.

Further, in the handrail 1, since the inner peripheral surface cover 59 is provided on the inner peripheral surface 5c of the Kasagi 5 over the entire length of the Kasagi main body 51, the inner peripheral surface 5c of the Kasagi 5 can be easily seen (construction of the handrail 1). In terms of environment) as well, the design can be further improved.

Further, since the handrail 1 is made of aluminum with the end pillar 2, the intermediate pillar 3, the cap tree 5, and the joint 6 aligned, it is possible to give the handrail 1 an overall sense of unity and, by extension, a sense of luxury. it can.

Further, in the handrail 1, the joint 6 is composed of two members (joint base 61 and joint cover 62). Therefore, when the joint 6 is cast, the cost of manufacturing the joint 6 can be reduced because the casting mold is cheaper than the casting of the one-piece joint.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. Further, the effects described in the present embodiment merely list the most preferable effects arising from the present invention, and the effects according to the present invention are not limited to those described in the present embodiment.

For example, in the above-described embodiment, a case where the inner peripheral surface cover 59 is provided on the inner peripheral surface 5c of the Kasagi 5 over the entire length of the Kasagi main body 51 has been described for the purpose of improving the design of the inner peripheral surface 5c of the Kasagi 5. However, for example, in an application where the inner peripheral surface 5c of the Kasagi 5 is difficult to see, it is not always necessary to provide the inner peripheral surface cover 59 over the entire length of the Kasagi main body 51, and only the hexagon bolts 12 and 13, the mounting bracket 7 and the screw 16 are provided. It may be provided so as to cover it.

Further, in the above-described embodiment, the end pillar 2, the intermediate pillar 3, the cap tree 5 and the joint 6 (that is, the exposed member) are all formed of aluminum for the purpose of improving the design of the handrail 1 as a whole. The handrail 1 that has been used has been described. However, all or part of these members may be formed from a material other than aluminum (for example, synthetic resin, stainless steel, etc.) as long as the strength required for the handrail 1 can be exhibited. Further, the surface of these members may be coated with a coating such as powder coating depending on the use of the handrail 1 and other situations.

Further, in the above-described embodiment, the handrail 1 in which the Kasagi 5 is horizontal has been described, but the present invention is not limited to this. It is also possible to apply the present invention to the slide 1 in the same manner.

Further, in the above-described embodiment, the handrail 1 in which the inner peripheral surface cover 59 is attached to the inner peripheral surface 5c of the Kasagi 5 has been described. At this time, if the cover body 591 of the inner peripheral surface cover 59 is made translucent, a lighting element (not shown) can be embedded in the back side of the inner peripheral surface cover 59 (inside the Kasagi 5) as needed. As a result, the handrail 1 can be provided with a lighting function while maintaining the high design of the Kasagi 5.

Further, in the above-described embodiment, the handrail 1 having a structure in which the cap tree 5 is supported by the pair of left and right end pillars 2 and the intermediate pillar 3 has been described. However, the structure may be such that the intermediate pillar 3 is omitted and the cap tree 5 is supported only by the pair of left and right end pillars 2. In this case, since the intermediate pillar mounting step can be omitted when assembling the handrail 1, the assembling work of the handrail 1 can be performed quickly and inexpensively.

Further, in the above-described embodiment, the case where the present invention is applied to the handrail 1 has been described, but structures other than the handrail 1 (for example, a partition for planting, a fence for a bollard, and a protective fence inside an automatic door) have been described.
