Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a handrail device that can be widely used on stairs, balconies, passageways, etc.

``Prior Art'' Many handrails installed in buildings are made of metal, and those made of stainless steel pipes are particularly popular because of their strength and corrosion resistance. Traditionally, this type of handrail was installed by placing a cap on the pillars erected on the stairs or floor and fixing it by welding. is being carried out. Therefore, not only does the work at the site require a lot of effort and time, but it also requires repairing welded parts and polishing to remove discoloration, which increases construction costs. There are drawbacks.

``Problems to be solved by the invention'' This invention solves the drawbacks of the conventional handrails as mentioned above, and in fixing the cap and support, it is possible to fit them together without using existing fitting work or means such as welding. To provide a handrail device which can firmly connect a cap and a post with a simple operation of fixing with screws and which can also freely respond to changes in the slope of the cap.

"Means for Solving the Problem" The present invention consists of fixing a piece retaining piece having a trapezoidal cross section on the lower surface of the Kasagi, and a pair of dovetail grooves and bolt holes that can be brought into close contact with the outer surface of the piece retaining piece. The divided pieces of
Clamp the pieces from both sides of the piece, and screw the bolts passed through the bolt holes of both pieces into the threaded holes of the connectors attached to the pillars to tighten both pieces to the pieces, and connect them to the piece. It is characterized by fastening the tool.

"Embodiments" Hereinafter, embodiments of the device of the present invention will be described with reference to the drawings.

In the figure, 1 is a pipe-shaped cap, which is made of metal such as stainless steel and has a vertical rectangular cross section. On the lower surface of the cap 1, there are piece retaining pieces 2, 2 formed in a trapezoidal cross section with slopes in the longitudinal direction of the cap 1.
Weld 3 at the required intervals in the longitudinal direction of Kasagi 1.
It is fixed by means such as Reference numerals 4 and 4 designate a pair of split pieces that are clamped to the aforementioned piece retaining pieces 2, 2, and dovetail grooves 5, 5 are formed on the upper portions of their opposing inner surfaces so that they can be brought into close contact with the outer surfaces of the piece retaining pieces 2, 2. At the same time, a bolt hole 6 is provided in the center of each of the dovetail grooves 5 in a direction crossing the dovetail grooves 5, and the length L of the dovetail grooves 5 is equal to the length of the connecting pieces 2, 2. It is formed to be longer than the required length.

Reference numeral 7 denotes a connector to be fastened to the splitting piece 4, and a fitting part 7a that fits into the upper end of the pipe support 8 is protruded from the lower surface, and a fastening part 7b is protruded from the upper surface. A horizontal screw hole 9 is screwed into the center of the fastening portion 7b.

Then, the pair of divided pieces 4, 4 have their respective dovetail grooves 5, 5 brought into close contact with the outer surfaces of the pieces 2, 2,
A bolt 10 is passed through those bolt holes 6, 6,
By screwing the bolt 10 into the threaded hole of the connecting tool 7 and tightening it, the connecting tool 7 is fastened to the split piece 4, and at the same time, the pair of split pieces 4, 4 are tightened together and the piece fasteners 2, 2 are tightened. It will be tightened.

``Function'' The present invention is constructed as described above, and the Kasagi 1 is carried to the site with the piece retaining pieces 2, 2 fixed to the lower surface, and each of the pillars erected at the site is 1
A connecting tool 7 is fixed to the upper end of 2. and,
In the field, if a pair of split pieces 4, 4 are joined to each piece retaining pieces 2, 2, and the bolts 10 are passed through the bolt holes 6, 6, and the ends are tightened into the threaded holes of the connector 7, the split pieces 4 are attached. , 4 and the piece fasteners 2, 2 and the connecting tool 7
The cap 1 and the support 8 are connected through the . In this case, the connecting tool 7 and the dividing pieces 4, 4 are 1
Since they are connected by a regular bolt 10, both can be rotated freely around the bolt 10 as an axis. Therefore, the Kasagi 1 can be moved from the horizontal position shown by the solid line in Figure 2 to the horizontal position shown by the solid line in Figure 2. It is possible to install the facility at any angle as shown by the chain line or even more inclined. Also, divided pieces 4, 4
The length L of the dovetail groove 5 is the length l that connects the piece retaining pieces 2, 2.
Since it is formed longer, relative movement is possible by the difference in length, so Kasagi 1
The coupling position of the strut 12 in the longitudinal direction can be freely adjusted.

"Effects of the Invention" As explained above, the device of the present invention has a piece retaining piece formed in a vertical cross section fixed on the lower surface of the cap, and a dovetail groove and a bolt hole that can be brought into close contact with each other on the outer surface of the piece retaining piece. Sandwich the pair of split pieces from both sides of the piece retaining piece, and screw the bolts passed through the bolt holes of both divided pieces into the screw holes of the connectors attached to the pillars to tighten both divided pieces to the piece retaining piece. At the same time, since the connectors are fastened to the split pieces, it is now possible to use factory-produced parts to replace metal handrails that currently require a lot of time and skill on-site, such as creasing, welding, and repair. It can be assembled and installed on site extremely easily, quickly and reliably, shortening the construction period and reducing construction costs. In addition, it is also possible to respond to changes in the slope of the Kasagi, as well as to installation errors with the support.
It has many advantages, such as being flexible and widely applicable to various types of handrails on stairs, balconies, passageways, etc.
