Description

  The present invention relates to a handrail provided with a handrail material provided on a staircase or the like and a handrail.

As a conventional handrail for stairs and the like, there is a handrail material and a handrail that are integrated by welding, nails, etc., and it is necessary to replace the whole to change the design of such a handrail. Expensive and troublesome.
Patent Document 1 describes a handrail for a staircase in which a handrail 12 is provided upright on a step board of a staircase, and a handrail material 1 is installed on a top end portion of the handrail 12 via a connecting member. As shown in FIGS. 4 and 5 of Patent Document 1, the connecting member has a substantially spherical receiver 6 below a mounting plate 8 that is in contact with the lower surface of the handrail material 1 and screwed. The screw shaft 4 is rotatably connected to the receiver 6 by a horizontal shaft 15. The screw shaft 4 of the connecting member is screwed into the nut 3 embedded in the upper end portion of the handrail and attached to the upper end portion of the handrail. The receiving body 6 is brought into contact with the recess on the upper surface of the cap 5 to connect the handrail and the handrail material.
In such handrails, the handrails are made decorative by shaving wood or integrally forming with a metal casting, but if you want to change the handrail design later, remove the handrails. I had to replace it. As described above, the connecting member between the handrail and the handrail material has the screw shaft 4 screwed into the handrail 12 from above, so that the connecting member can be separated from the handrail 12 unless the handrail material 1 is removed. Therefore, even handrail replacement cannot be easily performed.
Although it is conceivable to decorate the balustrade 12 by attaching an ornament, the connecting member cannot be separated from the balustrade 12 unless the balustrade material 1 is removed with the balustrade as described above, and the balustrade 12 is decorated from above. It was not easy to attach the decoration to the handrail later, and it was not an operation that anyone could do. Therefore, changing the design of the handrail is very laborious and expensive.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 2-4 is one Embodiment of the handrail of this invention, Comprising: The example of the handrail attached to the staircase 10 is shown. This handrail is provided with a plurality of handrails 2a, 2b, 2b,... Standing vertically along the side edge of the staircase 10, and the upper ends of the handrails 2a, 2b, 2b,. The handrail material 1 is erected via the connecting member 3. The handrails 2a and 2b are made of aluminum round bars. The handrails 2a at both ends are as thin as 40 mm in diameter and the middle handrail 2b is as thin as 20 mm in diameter. Each balustrade 2a, 2b has its lower end fixed to the upper surface of the tread plate of the staircase 10 with a metal fitting 11 and a screw 12. The handrail material 1 is made of a wooden round bar.

As shown in FIG. 3, a connection base 7 for connecting to the connection member 3 is attached to the handrail material 1. The connection base 7 has a connection part 13 that hangs down below the handrail material 1, and an attachment part 14 that extends in an arc shape along the outer periphery of the handrail material 1 from the connection part 13. Is screwed into the handrail material 1 and fixed to the handrail material 1. The connecting member 3 includes a base portion 16 having a substantially circular shape in plan view, and an arm portion 17 bent in a substantially L shape extending inward (passage side) from the base portion 16, and a distal end portion of the arm portion 17. The connecting portion 13 of the connecting base 7 fixed to the handrail material 1 is brought into contact with the outside, and the connecting base 7 is connected with a screw 5 (corresponding to “a horizontal axis perpendicular to the longitudinal direction of the handrail material” in claim 3). It is connected with. Therefore, when the screw 5 is loosened, the connecting member 3 can rotate with respect to the handrail material 1 with the screw 5 as a fulcrum, so that the connecting member 3 can cope with the angle change of the handrail material 1. A bolt insertion hole 18 and a counterbore hole 19 are formed at the center of the base portion 16 of the connecting member 3. A spacer 20 is sandwiched between the lower surface of the base portion 16 and the upper end surface of the handrail 2 b, and the base portion is viewed from above. The base part 16 is fixed to the handrail 2b by screwing the threaded portion of the hexagon bolt 4 inserted through 16 into a hole 21 provided in the center of the handrail 2b. Since the arm portion 17 is provided inward, the handrail material 1 is disposed at a position shifted inward from the axis of the handrail 2b, so that a person who goes up and down the stairs 10 is in the handrail material 1. It is easy to catch.
FIG. 3 shows the connecting member 3 for the middle thin handrail 2b. However, as shown in FIG. 4, the connecting member 3 for the thick handrail 2a at both ends also has the spacer 20 changed. The same thing is used.

  As shown in FIG. 2, a decoration 6 is attached to the middle balustrade 2b, thereby giving the balustrade 2b a design. As shown in FIG. 1-2, the decoration 6 is a ring-shaped thing that fits on the outer periphery of the handrail 2b, is provided with inclined surface portions 22 at the upper and lower portions, and has an outer diameter that decreases toward the upper and lower ends. A constricted portion 23 is provided in the middle. A balustrade insertion hole 24 provided vertically through the center of the decoration 6 is formed to be slightly larger than the outer diameter of the balustrade 2b.

  The ornament 6 is arbitrarily attached to the handrail 2b, and can be attached in advance before the handrail material 1 is installed, but can also be attached later by a resident. The procedure for retrofitting the decoration 6 will be described. First, as shown in FIG. 1-1A, the sponge seal 25 is attached to a position where the decoration 6 of the handrail 2b is to be attached. Next, as shown in FIG. 1-1B, the hexagon bolt 4 that fixes the connecting member 3 to the handrail 2b is removed using a tool such as a socket wrench, and then the spacer 20 is extracted. Since the handrail material 1 is eccentric inward with respect to the axis of the handrail 2b, the handrail material 1 does not get in the way when the hexagon bolt 4 is removed, and the hexagon bolt 4 can be easily pulled straight up. . Next, after loosening the screw 5 fixing the connecting member 3 to the connecting base 7 of the handrail material 1, as shown in FIG. 1-1 (c), the connecting member 3 is rotated around the screw 5 as a fulcrum. Let By extracting the spacer 20, a gap is formed between the lower surface of the connecting member 3 and the upper surface of the handrail 2b, so that the connecting member 3 is rotated without interfering with the handrail 2b. Then, since the connecting member 3 is separated from the upper end portion of the handrail 2b, the decoration 6 is fitted onto the handrail 2b from above as shown in FIG. As shown in FIG. 1-2 (e), when the ornament 6 is slid to the position where the sponge seal 25 is wound, the ornament 6 is held in that position by the sponge seal 25. A set screw 26 is inserted from the side, and the decoration 6 is fixed. When the ornament 6 is attached to the handrail 2b, the connecting member 3 and the spacer 20 are returned to their original positions, and the screw 5 and the hexagon bolt 4 are tightened and fixed again.

  FIG. 5 shows another example of how to attach the decoration 6. In FIG. 5A, four decorations 6 are attached to every other handrail 2b, and the decorations 6 are vertically attached to the middle part of the handrail 2b. In FIG.5 (b), the decoration 6 is attached in the arrangement | positioning which makes a wavy pattern. In this way, the decoration 6 can be freely attached according to the liking and sense of the resident, the number of attachments can be selected arbitrarily, and the attachment position can be attached at any position in the longitudinal direction of the handrail 2b.

  As described above, the handrail can freely attach the decoration 6 to the handrail 2b, and various designs can be easily realized. In addition, the decoration 6 is attached by removing the hexagon bolt 4 that fixes the connecting member 3 to the handrail 2b and rotating the connecting member 3 so that the connecting member 3 remains connected to the handrail material 1 and the handrail 2b. Since it can be separated from the upper end portion and the ornament 6 can be fitted to the handrail 2b from above, anyone can easily perform the attaching operation of the ornament 6. Since the handrail material 1 is in a position displaced inward from the axis of the handrail 2b, it is easy to remove the hexagon bolt 4 or fit the ornament 6 to the handrail 2b.

  FIG. 6 shows another embodiment of the handrail according to the present invention, and shows an example in which the handrail is applied to a fall-preventing handrail provided at the edge of the floor 27 facing the atrium in the building. Since the connecting member 3 is rotatable by a horizontal axis (screw 5) perpendicular to the longitudinal direction of the handrail material 1, even when the handrail material 1 is installed horizontally as in the present embodiment, the connecting member 3 is used for stairs. The same connecting member 3 can be used, and the design can be changed by retrofitting the decoration 6 to the handrail 2b freely in the same procedure as described above. The handrails 2a, 2b and the decoration 6 can be the same as those for the staircase.

  7 and 8 show another embodiment of the connecting member 3. In the present embodiment, the arm portion 17 of the connecting member 3 has a screw 5 from below with respect to the connecting base 7 fixed to the handrail material 1 (the “vertical position at a position displaced from the axis of the handrail in claim 4”). When the ornament 6 is fitted to the handrail 2b, the hexagon bolt 4 is removed and the connecting member 3 is attached to the screw 5 as shown in FIG. Since the connecting member 3 is separated from the upper end portion of the handrail 2b by rotating the handpiece 2b, the decoration 6 can be easily fitted to the handrail 2b from above. In the case of the present embodiment, the connecting member 3 can be rotated without removing the spacer 20, and the spacer 20 can be omitted.

FIG. 9 shows still another embodiment of the connecting member 3. In this embodiment, the horizontal screw 5 parallel to the longitudinal direction of the handrail material 1 is connected to the connection base 7 in which the arm portion 17 of the connection member 3 is fixed to the handrail material 1 (“handrail in claims 5 and 6”). It corresponds to an axis “corresponding to the longitudinal direction of the material 1”). The screw 5 is at a position shifted from the axis of the handrail 2b. When fitting the ornament 6 to the handrail 2b, the hexagon bolt 4 is removed and the connecting member 3 is turned upward by turning the connecting member 3 around the screw 5 as shown in FIG. 9B. It can isolate | separate from the upper end part of the handrail 2b, and the decoration 6 can be easily fitted to the handrail 2b from the upper part. Since the rotation shaft (screw 5) of the connecting member 3 is located away from the axis of the handrail 2b, the connecting member 3 can be rotated without removing the spacer 20, and the spacer 20 is omitted. You can also. Moreover, the arrangement position of the handrail material 1 can be adjusted inward and outward by changing the fixing angle of the connection base 7.
When the spacer 20 is provided, the rotation shaft (screw 5) of the connecting member 3 can be provided at a position directly above the handrail 2b.

  The present invention is not limited to the embodiments described above. The specific form of the connecting member, the direction of the rotating shaft, and the like can be changed as appropriate. Moreover, it can change suitably also about the material, shape, etc. of a handrail or a decoration. It is also possible to arrange the handrail material directly above the handrail.
