Abstract

(57) [Summary] [Purpose] The present invention provides a new ladder band assembly structure that eliminates pin holes on the outside, has an excellent end face shape, does not come off the pins, and can easily perform a wide range of adjustments. It is intended to provide. In the present invention, one or a plurality of inner members are pulled out and removed between inner and outer members by means of inner blind holes provided in each of the outer members on both sides which are formed with a step difference between the inner and outer members. A unit part is formed, and a plurality of unit parts are connected in parallel, an end piece part is fitted to one end of the parallel body, and a U-shaped ladder part is fitted to the other end, and can be removed with an adjust pin. And a ladder band assembling structure.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a ladder band assembly structure, and more particularly, to a device in which unit parts can be successively disassembled simply by pulling out and removing the adjust pin at the end of the band, thereby facilitating the adjustment of the length of the band.

[0002]

[Prior art]

 Conventionally, this type of ladder band is knitted by connecting both ends of the inner member straddling the outer members on both sides to the opposing outer members by connecting the pins to the opposing outer members, and adjusting only some of the non-end piece side ends. They are connected using pins.

[0003]

[Problems to be solved by the invention]

 In such a ladder band, not only is it difficult to see two pins inserted into the outer member, but also the outer member is restricted in shape due to the presence of the pin holes, so that the surface becomes larger or has a streamlined shape. And it was not possible to make the parts thin. In addition, there is a risk that the pin may come off and break off while repeating bending and tensioning of the band, and furthermore, there is a problem that the adjustment can be performed only for a very limited length.

[0004]

[Means for Solving the Problems]

 According to the present invention, one or a plurality of inner members are detachably inserted between the outer members by means of inner bag holes provided in each of the outer members on both sides which are formed with steps on the inner and outer sides, and pins are freely inserted and connected. A unit part is formed, a plurality of unit parts are fitted and arranged in parallel, an end piece part is fitted to one end of the parallel body, and a ladder part having a U-shape in plan view is fitted to the other end. By fixing, a ladder band is assembled and formed. The outer members on both sides forming the unit part do not have the outer surface of the pin hole formed by the formation of the inner bag hole, and the pins are fitted at both ends by the bag hole so that there is no risk of detaching and removing the terminal ladder. To solve this problem, all the unit parts can be disassembled simply by pulling out the adjustment pins of the parts, and the adjustment work for length adjustment can be performed widely and easily. It was.

[0005]

[Embodiment of the invention]

 This will be described below with reference to the drawings.

[0006] Outer members 1a, 1b on both sides are formed by cutting, as if two inner and outer plate members were shifted by half each, with steps inside and outside. The outer members 1a and 1b are provided with inner bag holes 2a and 2b, respectively.

[0007] The inner members 3a, 3b, 3c are arranged and inserted inside the outer members 1a, 1b, and one end of the inner member 3a, 3b, 3c is pierced and connected, and one end of the pin 4 is fitted into the inner bag hole 2a. The unit part 5 is assembled and formed in such a manner that the other end is fitted into the bag hole 2b of the outer member 1b.

As shown in FIG. 2, the unit part 5 has a pin 4 fitted between the other ends of the inner members 3a, 3b, 3c. The unit parts 5 are banded in such a manner that one outer member, for example, 1b is removed, a large number of them are fitted and arranged in parallel, and after the fitting is completed, the outer member 1b removed is fitted and fitted. An end piece part 7 and a ladder part 8 having a U-shape in a plan view are fitted to the front and rear ends of the body 6, and are fixed by press-fitting an adjust pin 9. The end unit part 5a connected to the end piece part 7 is provided with a through hole 2c for press-fitting the adjust pin 9 therein.

When adjusting the length, the adjust pin 9 of the ladder part 8 is pulled out. Then, the ladder parts 8 are separated, and the unit parts 5 can be sequentially disassembled. Therefore, the necessary number of parts are removed and the ladder parts 8 are re-fitted and stopped.

[0010]

[Effect of the Invention] Since the present invention is configured as described above, the outer member of the unit part does not have a pin hole exposed on the outer surface except for the adjusting pin insertion portions at both ends, so that the surface is enlarged or made streamlined. The effect that the thickness of the sheet can be made thinner is produced.

Since the pins connecting the unit parts can be fitted at both ends by the blind holes, the pins do not come off even if they are repeatedly bent and stretched. In addition, a wide range of length adjustments can be achieved simply by pulling out the adjust pin at one end, which produces many excellent effects.
