Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a riser height adjustment structure for an assembled staircase, and the main part thereof is a sub-plate support block; Lift up the outer cylinder-3) from the front part of the sub-plate support block Ill, and place it immediately on the 1st floor.
Protective opening + inner surface of Il + 21vc loosely connected, widening eye and one Stop protrusion (
6) Fully formed, this locking - J + 41'i inner front, 2)
While fitting each of the upper dowels, the locking protrusions 16) of the locking protrusions 14) protrude from the four holes Lfc through hole J) in the same direction of the cylinder (2), and the internal t211c head Insert the bolt (8) with the part (7) facing up, and insert the insertion hole (+10) made through the truncated cone-shaped expanded part (9) into the bolt (8) near the head (7). For VC expansion, the member (9) is shaped like a J shape! Outside the Taber of the member (9) that is straight at the angle of 1/I8d
Line up surface (II) + L 'J yy + 41 [Forged, truncated circle, princess-shaped nut (13) with bolt + 81 VC screw and tighten nut (131 taper outer circumference 1112) Keto 1 thread stop yy In (4), there is something related to the VC of the offering height adjustment of the 11th stage of the 11th stage of the assembly, which is ``Rest in peace and become my second brother!''

In the case of assembled stairs in Canada, as shown in Figure 1 [Treads, 14
) is attached to the tread support block (1), which is simply fixed with bolts 8).
There was a soul while I couldn't do it.

The present invention has been made in consideration of the above points, and its purpose is to provide a riser restraint structure for one-stage assembly which can adjust the riser height. It is in.

Hereinafter, the present invention will be explained in detail based on the center m column shown in the figure. Assembling 14 yen stage (~ is tread support block + I) diagonally upward
They are connected by grooves and holes. Tread support block ++)
The inner cylinder (2) is raised from the stepped part of the main body (1a) which has scrap plate pattern wings (15) on both IIs.
) The outer cylinder (3) is vertically installed from the front part of the cylinder (n). Then, the outer cylinder i3) of the tread support block (1) is loosely fitted with the V'31 opening (2) of the tread support block il) located immediately below vC. There are through holes (6) at one-foot intervals in the circumferential direction in the upper valley part of the inner cylinder) 2)! ! It is set up. (4) is formed by bending an elastic wire! It is a one-thread stop, and is free to expand outward. The locking jig (4) has locking protrusions t5 formed outwardly at one foot intervals in the circumferential direction. 2 +lI! The locking jig (□4) of iI is the inner cylinder 12
The locking protrusions -6) of the locking ring (4) are made to protrude outward from the single force hole (6), respectively, by means of a latch 11 on the upper side of the locking ring (4).

(9) is a truncated or calust-shaped expanding member, which has a protrusion hole +10) extending in the upward direction, and its outer periphery is a tapered outer circumferential surface (1). +13) is a nut with a truncated conical shape, and the outer circumference V is a tapered outer circumferential surface 112). I81 fj: A bolt that locks the inner cylinder (2) and the outer surface (3) and connects them indirectly through the bottom (4). This is something that only people can do. vi at the top of bo11/t81,
The expansion member (9) is loosely fitted in contact with the F side of the head (7), and the nut 13) is screwed into the threaded portion X16) of the bolt 8). And Natsuto +13. When the l is rotated, the distance Pi [ffσ)) between the expansion member (9) and the Natsuto state changes, and the 7-d 1-thread ring (4) The expansion member (9) has each taper facing outward, [I] (II) (12) fully slides tJ5VC widening) and the locking protrusion (5) is attached to the inner circumferential surface of the outer rfi + 31. This will result in Therefore, the riser height can be adjusted to UQ by the rotation of the bolt 8) and the upward and downward slide of the bolt 8) outward (7) relative to the inner surface (2). Similarly, the upper part of the outer cylinder +31 is integrally formed within the main body (la) and is directed outward (3).
: The end is an opening 07). Therefore the bolt (
8) Rotate the fake treadle (I4) to the main body (L).
(a) Before placing the coins in the bank, they are operated by using a spanner from the opening (by hand), making it easy to dispense the coins with a riser system. Moreover, when the locking link (4) is loosened, the inner cylinder (2) and the outer cylinder (3) rotate 8I in the circumferential direction around the entire center of the bolt (8)! Since it can be bent, it is possible to make bends in the 14-stage assembly. When tightening the bolt (8), the force should be distributed evenly to the locking protrusion (6) of the lock (4), and the position when the tread support block 111 is assembled is +ttt'r. It is easy to set the dimensions of the 14-stage mounting position, which makes it difficult to occur. Figure 6 shows 1+!I in addition to the locking seat (4), and connects the ends of the elastic wires together. Hey, moth 14i
It is Vc.

As described above, the non-invention is as follows.
- Loosely fit into one of the tread support blocks located immediately after the installation, and the lock that can be expanded freely -) is moved in the circumferential direction V
A locking protrusion is formed which presses against the inner circumferential surface facing outward at intervals of this bore, and this locking link is attached to the upper part of the inner cylinder. The locking protrusions were drilled at intervals of one foot in the circumferential direction of the cabinet, and the bolts protruded from the holes, and the bolts were inserted in the same plane with the heads facing upward, and were inserted into the truncated circular expansion members. (4! Place the opening hole near the head of the bolt, hold the member upside down, and fix the tapered outer circumferential surface of the expanding member on the top line.) Since the nut R is attached to the bolt and the outer peripheral surface of the nut is brought into elastic contact with the retaining link F, when the bolt is tightened, the retaining link expands and the retaining protrusion is able to come into pressure contact with the outward inner peripheral surface. There are 40 points to be made, such as connecting the upper F tread support 1 block, and therefore sliding the outer surface upwards relative to the inward direction, tightening the bolts, and adjusting the riser height by 2'. Moreover, since the height can be determined by sliding outward against the inner 1 m vC, there is the advantage that it can be adjusted steplessly.

Claims (1)

[Claims] +1) Raise the inward side from the rear of the fan plate support O-tsuku, install the outer surface from the front of the layer plate support ``J-lock'', and immediately install it. loose fit,
The expanded locking links are formed with locking protrusions that protrude outward at one-foot intervals in the same direction to press against the inner circumferential surface of the outer cylinder, and these locking links are moved inward and upward. At the same time, the locking protrusion of the locking link is inserted into the inner cylinder with four holes spaced at regular intervals in the circumferential direction. , Loosely fit the Vc expansion member into the rigid part of the insertion hole r bolt passed through the radial expansion member, and press the outer circumferential surface of the expansion member into the upper line stop Y, and cut. This riser height adjustment structure for an assembled staircase is characterized in that a fan-shaped nut is attached to a bolt and the outer circumference of the nut is brought into elastic contact with an F locking link RTC.
