(Patent application After inserting the stair unit 4 into the cylinder of another unit as shown in Figure 3, the stair unit 4 is adjusted to a predetermined angle of 1 angle and height position (II). Then, fix both using fixing machine #N7 (17 in the figure), and repeat the steps to complete the curved staircase. f115 fat, tread 4v, 6Q,

In order to popularize the stairs, it is essential to develop a fixing mechanism that allows for easy height adjustment and angular displacement between stairs.

In response to such technical requirements, the present inventor previously proposed a fixing mechanism shown in FIG. 4. (Japanese Patent Application No. 56-68885) That is, its structure is that a cylinder 1 that projects upward has two rows of circular holes 10 with symmetrical back holes, and a cylinder that can slide into the circular holes 10.

As a result, the pinot 11 is pushed outward, and its tip is pressed against the inner circumferential surface of the other flute 1 body 2', fixing the pieces 1-4 and 4' together.) Sign.

Such a fixing mechanism certainly has a height adjustment and angular displacement of l-11.
However, due to the mechanism in which the outer dimensions of the fitted cylinders 1 and 2' are fixed in a floating state, the fixation is self-restricted, and
It has the disadvantage that fine adjustment of the height between stair units and the angle adjuster r is difficult.

The fixing mechanism for the history is attached to the second floor floor board 6.
- From part 6, near 7, or treated as the first floor (-1/ko 1, part yuso I, (not shown), all starts, but from part 1, near , start Jl″J
In order to prevent 1-each stairway from falling off, temporarily set each stairway by 1 inch to support the throat 4. In view of the shortcomings of the prior art, the above-mentioned height and angle IC-variation 1'f adjustment, Iiyamame and Hon. Provides a stair-1-soto fixing machine tj6 that is easy to identify! Aiming for J1, that! 11j The point and place are 1 of the small diameter cylinder.
One end protrudes from the center 1, and a threaded part (A) is formed in the mid-abdominal part of the large-diameter segmental body, and a /j IJ ring-shaped locking part is located in the center. Front: Threaded part) Form a threaded hole for MK screwing, and its outer shape inside the large diameter cylinder,
The fixing mechanism of the stair unit is formed by sandwiching the front ML engaging part from above and below so that one force can be combined, and is made of a nut member of i5-'pJ.

Hereinafter, the present invention will be explained based on the drawings.

By forming the keel part of the nut part 4 in the shape of a single character, and forming the 1° part nut in the shape of a single character, one part of the nut part 28 can be made transparent with the rotating jig 30. Then, the F part nut part 27 is configured to have one rotation function.

To explain the operation of this embodiment with such a configuration, first, in height adjustment, -C is elm knot 1 - and 2:3;+'

, it is sufficient to adopt an assembly procedure in which fine adjustments are made during basic assembly. In this embodiment, it is extremely easy to carry out such two-step adjustment, and this point is completely different from the prior art.

That is, to explain the case where the assembly is first started from the door unit (not shown), the lower nut part 27 is screwed into the threaded part 4'A26 of the cylindrical body 21 one turn, and then the nut part 7 is assembled. ≧ From the pre-planned surface, adjust the height of the top surface 23; Insert from three sides C1・(1i11 Tsui nodori 27 upper surface of cylinder body 2

The part unit 7 and the part unit (j' shown in the figure) are completely fixed at a predetermined height position. Next, a rotating jig 30 is used to distribute the mismatch between the drawing dimensions and the site machining method or the errors that occur at the time of t: 1 to 1 to each stair corner 24. !

A fixing plate 42 is disposed in the middle heat section of the cylinder, and a screw part 43 is provided on the central axis of the cylinder and protrudes upward. to fix. Reference numeral 44 denotes a first side nut part, which has a screw hole 45 screwed into the center thereof to be screwed into the threaded part 43, and its outer shape is formed into a cross shape that can be fitted into the cylinder body 41. 46('', locking part 4U
A cylindrical body 47 having a locking part 48 formed at its lower end, a collar 49 surrounded around its upper end, and a pair of screw holes extending outward from the cylindrical body 47; 47
The outer diameter of the flange 49 is fixed on the inner peripheral surface of the small-diameter cylinder 41, and the outer diameter of the collar 49 is determined on the upper surface of the large-diameter cylinder 51. 50 is fixed to two sides of the staircase unit t and 53'J by screws 52. Reference numeral 54 designates an upper nut part ``a'', which has a screw hole 55 screwed into the center thereof to be screwed into the threaded part 43, and its outer shape is formed into a single character shape that can be freely integrated into the connecting part 46. .

Next, the operation of this embodiment will be explained.

In the embodiment, the small diameter cylindrical body 41 is inserted into 11 over almost the entire inner periphery of the body 51, so that the units 53 are fixed together. death/
Even in this case, there is little risk of looseness or alignment of the axis.

In addition, in the false example, part 11 A46 was fixed to the stair coaster l□5:3', but the upper unit 7 was fixed to the set\'1. When starting, the locking part -IA46 will be constantly tilted in the F direction, so even if the locking part 4246 is not fixed to the stair unit 53', it must be locked so that it does not move downward. This makes it easier to insert the small-diameter cylinder/11. As described above, the present invention allows the 7'1. (d:, each stair unit frj
The height can be adjusted coarsely with the K'lj body, and the angle can be adjusted and fixed while the stairway Yuno) and 171j are in a rotatable static position by holding the upper part of the suspension part with a pair of nut parts 44. Assembly work has become extremely easy, and it has become 111゛. 41 (When starting the assembly from the unit unit, in order to prevent the risk of the 1st stage unit falling off, use a support rod etc. to hold it until it stands up in each row.) Assembly with no peace of mind: This leads to a significant reduction in man-hours.

My husband told me that the present invention is extremely difficult to achieve with conventional technology (Teatsu/C1).
IXJ, +i+I and γ make fine adjustment during the main assembly after O'11 adjustment easier than ever, and its practical value is extremely high.
