Abstract

An upper circular plate bolt and a lower circular plate nut are provided as hardware for fixing a body movement assist device for preventing damage to a beam to a plywood for floor structure on the floor. A central pipe with a deformed plate fixed to the upper end is placed in a hole in a floor structure plywood K on the floor, the central pipe is lowered into the back of the ceiling, and is positioned on the four crosses from the hole into which the central pipe is inserted. The shape of the upper circular plate U fixed to the upper end of the bolt B inserted into the four bolt holes of the floor structure plywood K is an upper circular plate bolt, and each of the four upper circular plate bolts is the upper surface of the floor structure plywood K. The bolt part B was placed under the floor structure plywood K. The upper end of the long nut N is fixed to the lower side of the center hole of the lower circular plate C arranged on the lower surface of the floor structure plywood K, and the bolt hole EA is opened on the lower surface of the lower circular plate C and the long nut N. The shape to which the plate piece E was fixed was used as the lower circular plate nut. [Selection] Figure 2

Description

  The present invention is a field of fixed hardware which can attach a personal mobility assistance device to plywood for floor structure on the floor.

  In wooden houses after 2004, the use of joists has decreased sharply on beams, while plywoods for floor structures are attached directly on beams in home constructions of foreign countries, so the body movement assistance device is in the ceiling There is a need for a metal fitting that can connect the upper end of each anti-rolling steel material fixed on the lower end portion of the central pipe disposed inside and diagonally above the cross four sides with the plywood for floor structure on the floor.

  A fixed metal that can be fixed to the lower end of the center pipe of the body movement assistance device placed in the ceiling and placed on the cross four diagonally, the upper end of each anti-rolling steel can be attached to the plywood for floor structure on the floor Become.

  To achieve the above purpose, put the center pipe with the upper end fixed to the center of the deformed plate into the hole in the floor structure plywood, lower the center pipe into the ceiling, and cross the hole from the hole to put the center pipe The upper circular plate is fixed to the upper end of four bolt holes in the floor structure plywood to be opened in four positions, and the upper circular plate is made into an upper circular plate bolt. Mounted on the top of the bolt part came down.

  An upper end of a long nut is fixed to the lower side of the central hole of the lower circular plate, and a plate piece having a bolt hole is fixed to the lower surface of the lower circular plate and the long nut. .

  By screwing the bolt portion of the upper circular plate bolt into the long nut of the lower circular plate nut arranged on the lower surface of the plywood for floor structure, the upper circular plate portion and the lower circular plate portion hold the plywood for floor structure Lower ends of four anti-rolling steels, each bolt hole formed in each plate piece of each lower circular plate nut and each bolt hole at the upper end of each anti-rolling steel is overlapped and fixed by bolts and lowered diagonally A plurality of pins fixed to the lower end of the central pipe where the plurality of pins are fixed to the lower surface and the small handle is fixed to the upper surface to open each pin portion of the bolt turning tool having a large inner circumference to the upper circular plate The bolt part of the upper round plate bolt is put into the hole and turning the small handle, and the upper round plate bolt and the lower round plate nut can be firmly clamped to the floor structural plywood.

  Fixed to the lower end of the center pipe in the back of the ceiling and fixed to the floor structure plywood by fixing the upper end of each of the four anti-rolling steel members raised diagonally to the floor structure plywood. The load can be distributed over a wide range of plywood for floor structure with four parts of the upper circular plate and the deformed plate by distributing the weight to be loaded on the center pipe and the four rolling prevention steel materials.

The central pipe J with the deformed plate R fixed to the upper end is put in the hole of the floor structure plywood K on the floor, the central pipe J is lowered in the ceiling T and the cross from the hole for putting the central pipe J The upper circular plate U is fixed to the upper end of the bolt B at four bolt holes in the floor structure plywood K to be the upper circular plate bolt. The bolt portion B mounted on the upper surface was delivered to the lower side of the floor structure plywood K.

The upper end of the long nut N is fixed to the lower side of the center hole of the lower circular plate C arranged on the lower surface of the plywood for floor structure K, and the bolt holes EA are opened in the lower surface of the lower circular plate C and the long nut N A shape in which the plate piece E is fixed is a lower circular plate nut.

By screwing the bolt B part of the upper circular plate bolt into the long nut N of the lower circular plate nut, the upper circular plate U part and the lower circular plate C part sandwich the floor structure plywood K, and each of these lower circular parts 4 pieces of each anti-rolling steel Y that is bolted on each plate piece E of the plate nut and each of the anti-rolling steel material Y is overlapped with the bolt hole at the upper end of each plate Y and fixed with bolts BB and lowered in four directions Each lower end is fixed to the lower end of the central pipe, where a plurality of pins P are fixed to the lower surface, and a small handle H is fixed to the upper surface, and each pin P portion of the bolt turning tool F having a large inner circumference HN is The upper circular plate bolt and the lower circular plate can be clamped tightly to the plywood K for the rotating floor structure by turning the small handle H in each pin hole UA opened in the circular plate U and turning the small handle H. nut.
