  As shown in FIGS. 1, 2, and 3, a cutting waste collecting jig 2 for a rain gutter 1 (eave fence, vertical hoist) as a long material according to the present invention includes a cutting waste collection box 3 and this cutting waste. A pair of auxiliary cutting boxes 4 disposed on both sides of the recovery box 3 are formed.

 The cutting waste collection box 3 is a rectangular parallelepiped having a concave shape having an opening 5 at the upper end 3a and having an outer shape of length L, width M, and depth N. The pair of auxiliary cutting boxes 4 has a concave shape having an opening 6 at the lower end 4a and the outer shape is a rectangular parallelepiped having a length L1, a width M1, and a depth N1, and the upper end of the auxiliary cutting box 4 is provided at the lower end 4a. A height adjuster 7 is provided for keeping the portion 4b and the upper end portion 3a of the cutting waste collection box 3 substantially horizontal.

  The height adjuster 7 includes a shielding plate 10 (a rectangular plate having a length L1, a width M1 and a thickness T) covering the opening 6 of the lower end 4a of the auxiliary cutting box 4 and a groove for slidably holding the shielding plate 10. The mold material 11 (the groove width T is the same as the thickness T of the shielding plate 10). And the groove mold material 11 is attached in parallel along the lower end part 21 of the side wall 20 of the auxiliary cutting box 4 so that the groove part 11a faces. A pair of bases 14 (a square member having a length L1, a width M3, and a height N3) are attached to the back surface 12 of the shielding plate 10 in the vicinity of both end portions 13 of the shielding plate 10 so as not to interfere with the groove mold material 11.

Here, the upper end 4b of the cutting auxiliary box 4 and the upper end 3a of the cutting waste collection box 3 are kept substantially horizontal,
N = N1 + N3-t1. (The thickness t1 of the groove mold material 11 is assumed.)
Furthermore, a pair of guides 8 that sandwich the gutter 1 and a locking tool 9 that is slidably locked to the cutting waste collection box 3 are provided at the upper end portions 4 b of the pair of cutting auxiliary boxes 4. .

  The pair of guides 8 has a triangular cross-sectional shape with a width R1 and a height R2 of the bottom surface 8a, and a length L2 is formed by protruding from the length L1 of the auxiliary cutting box 4 by R3.

 The pair of guides 8 are fixed by bolts or the like (not shown) through holes 25 formed in the vicinity of the front wall 22 and the rear wall 24 of the upper end portion 4b of the auxiliary cutting box 4. A plurality of mounting widths S of the pair of guides 8 (distances between the holes 25 arranged symmetrically) are appropriately determined according to the assumed shape of the rain gutter 1.

  The locking tool 9 has a rectangular cross section with a width R4 and a height R5, and has a length M1 (the same length as the width M1 of the shielding plate 10) and a gap R6 with respect to the rear wall 24 of the auxiliary cutting box 4. The guide 8 is fixed to the bottom surface 8a. At this time, the gap R6 is formed in the cutting waste collection box 3 so that the wall 3b of the cutting waste collection box 3 sandwiched between the locking tool 9 and the rear wall 24 of the auxiliary cutting box 4 can be slid stably. The wall 3b is formed to have substantially the same length as the plate thickness t2.

  The auxiliary cutting box 4 includes a passage hole 23 through which the base 14 of the shielding plate 10 can freely slide even if the shielding plate 10 is inverted.

  In addition, a magnetic body 30 is provided on the inner surface 3c of the lower end portion of the cutting waste collection box 3 in substantially the same range (length L, width M) as the inner surface 3c of the lower end portion, and the upper end portions 4b of the pair of auxiliary cutting boxes 4 are provided. The magnetic body 31 is provided on the (outer surface of the upper end) as long as the guide 8 and the hole 25 are not covered.

  In addition, a pair of cutting auxiliary box 4 becomes a structure which can be accommodated in the cutting waste collection box 3, as shown by the arrow.

  Here, the material of the cutting waste collection box 3 and the auxiliary cutting box 4 is not particularly limited as long as it has rigidity that does not distort when the rain gutter 1 is cut. For example, metal, wood, synthetic resin, or the like is used. As the material of the rain gutter 1 to be applied, for example, iron is used as a core material for a synthetic resin such as hard polyvinyl chloride, polyethylene, polypropylene, and polycarbonate.

<Operation of a jig for collecting scraps of long materials>
As described above, since the rain gutter 1 can be held from both sides by the pair of guides 8, the cutting operation is stable when cutting with a cutting tool such as a saw, and the gutter 1 can be cut easily and accurately.

 The pair of guides 8 are provided with a plurality of mounting widths S in accordance with the shape of the rain gutter 1 to be applied, so that versatility is improved.

  The long material cutting waste collecting jig 2 is formed in a wide range by a cutting waste collecting box 3 and a pair of cutting auxiliary boxes 4 disposed on both sides of the cutting waste collecting box 3. Even if it is long, it can be stably held, so that the gutter 1 can be cut easily and accurately.

 Since the upper end portion 4b of each of the pair of auxiliary cutting boxes 4 is provided with a locking tool 9 that is slidably locked to the cutting waste collection box 3, the rain gutter 1 can be used at a limited height with limited footing. Even when cutting, it is possible to work by selecting a stable locking position as much as possible, thus improving safety. Moreover, the collection efficiency of the cutting waste to the said cutting waste collection | recovery box 3 can also be improved by matching the latching position with conditions, such as a wind direction.

  Furthermore, since each cutting auxiliary box 4 can be slid separately with respect to the cutting waste collection box 3, even if it is a long rain gutter 1 that is not linear, each locking position is selected according to the shape. It is also possible.

  Since the magnetic body 30 is provided on the inner surface 3c of the lower end portion of the cutting waste collection box 3 and the magnetic body 31 is provided on the upper end portion 4b (upper end outer surface) of the pair of auxiliary cutting boxes 4, the cutting waste is efficiently used in a wide range by magnetic force. Since all can be collected well, cutting waste will not be scattered around.

  As shown in FIGS. 4 and 5, the auxiliary cutting box 4 is formed with a passage hole 23 through which the base 14 of the shielding plate 10 can freely slide even if the shielding plate 10 is inverted as described above. The height adjuster 7 provided at the lower end portion 21 of the auxiliary cutting box 4 is once pulled out of the auxiliary auxiliary box 4 and then turned upside down so that it can be reattached to the auxiliary cutting box 4.

  In this state, the base 14 of the shielding plate 10 of the height adjusting tool 7 is stored in the auxiliary cutting box 4 so that the overall height of the auxiliary cutting box 4 is changed from V1 = R2 + N1 + N3 to V2 = R2 + N1. The height of the box 4 is lowered by N3.

Then, as shown in FIG. 6, the entire pair of auxiliary cutting boxes 4 in the state shown in FIG. (The cutting waste collection box 3 and the cutting auxiliary box 4 are formed in a relationship of N ≧ V2.)
For this reason, since the cutting waste collection jig 2 is made compact, it is easy to carry. Further, since the shielding plate 10 of the height adjusting tool 7 of the cutting auxiliary box 4 substantially becomes a lid of the cutting waste collection box 3, the stored cutting waste (the cutting waste stored in the cutting waste collection box 3 and the cutting assistance) The cutting waste captured by the magnetic body 31 of the box 4 can be reliably removed from the work site without scattering.

 Furthermore, since the inside of the cutting waste collection box 3 can be used as a storage with a lid for tools and parts such as a cutter, the convenience of carrying to the site is enhanced.

  As mentioned above, although embodiment of this invention was described based on drawing, all said Example showed an example of this invention, and it cannot be overemphasized that this invention should not be limited to these. Absent.

  For example, the cutting auxiliary box 4 may be stored in the cutting waste collection box 3 without being turned upside down.

  The shape of the pair of guides 8 does not necessarily have a triangular cross section, and may be determined according to the shape of the rain gutter 1 to be used.

  The mounting hole 25 of the guide 8 may be a long hole, and if it is a long hole, the mounting width S between the guides 8 can be further arbitrarily adjusted.

  The material of the gutter 1 may be made of synthetic resin that does not contain iron. In this case, the magnetic body 30 of the cutting waste collection box 3 and the magnetic body 31 of the pair of cutting auxiliary boxes 4 are not particularly required.
