The side piece holding portion 211 that holds the side piece 421 on the ridge side and the eave side that holds the side piece 422 on the eave side are provided. Side piece holding part 212. The side piece holding portion 21 preferably contacts the entire outer surface of the side piece 42 and holds the entire side piece 42, but does not need to contact the entire outer surface of the side piece 42.

  The width of the side piece holding part 21 (see FIG. 3, the length in the short direction, the vertical length in FIG. 3) is formed longer than the width of the side piece 42 of the eaves 4.

  A grip portion 23 that grips the distal end portion of the side piece 42 is provided at the end portion of the side piece holding portion 21 corresponding to the ear portion 43 (this is referred to as a distal end portion). The grip portion 23 includes an inner protruding piece 231 protruding inward from the tip end portion of the side piece holding portion 21, a rear protruding piece 232 protruding from the inner end portion of the inner protruding piece 231 to the back side (that is, the bottom piece 41 side), Have

  The inner protruding piece 231 comes into contact with and pushes the distal end surface of the side piece 42 (the surface opposite to the bottom piece 41 of the ear portion 43). That is, the inner protruding piece 231 serves as a tip pushing portion that pushes the tip of the side piece 42 toward the bottom piece 41.

  The rear protruding piece 232 restricts the inner protruding piece 231 from moving outward. That is, the rear protruding piece 232 suppresses the inner protruding piece 231 from moving outward and dropping off from the distal end portion of the side piece 42.

  The bottom piece facing portion 22 is provided between an end portion (this is a base end portion) on the side corresponding to the bottom piece 41 of the side piece holding portion 211 on the ridge side and the side piece holding portion 212 on the eaves side. The bottom piece facing portion 22 is opposed to the outer surface of the bottom piece 41.

  In the first embodiment, flanges 24 are formed at both end edges of the side piece holding portion 21 and the bottom piece facing portion 22 in the longitudinal direction of the eaves rod 4.

  The jig body 2 has a guide portion 11 that guides the movement of the cutting blade that cuts the eaves rod 4. Although a saw is mentioned suitably as a cutting tool which has a cutting blade, Especially it is not limited to a saw. In the first embodiment, the flange 24 constitutes the guide portion 11.

  The jig body 2 has an insertion port 25 into which the insertion member 3 is inserted. In the first embodiment, an insertion port 25 having a rectangular shape that is long in the lateral direction and that opens to the ridge side is formed at the end on the bottom piece facing portion 22 side of the side piece holding portion 211 on the ridge side.

  As shown in FIG. 3, the insertion member 3 is inserted between the bottom piece 41 and the bottom piece facing portion 22 through the insertion port 25 in a state where the jig body 2 is attached to the eaves rod 4. As a result, the insertion member 3 cuts between the bottom piece 41 and the bottom piece facing portion 22 and pushes the bottom piece 41 and the bottom piece facing portion 22 in a widening direction. In the first embodiment, the insertion member 3 is configured by a leaf spring.

  More specifically, the insertion member 3 has a substantially rectangular shape that is long in the insertion direction in plan view. The insertion member 3 is formed of a synthetic resin in the first embodiment.

  The insertion member 3 has a smooth curved shape in which a middle portion in the insertion direction is convex in a side view orthogonal to the insertion direction. The convex part 31 formed in the intermediate part of the insertion member 3 becomes an eaves pressing part that presses the bottom piece 41 of the eaves 4. The distal end portion 301 in the insertion direction of the insertion member 3 serves as a jig body pushing portion on the distal end side that pushes the bottom piece facing portion 22 of the jig body 2. Further, the rear end portion 302 of the insertion member 3 in the insertion direction serves as a jig main body pressing portion on the rear end side that pushes the edge 251 on the bottom piece facing portion 22 side of the insertion port 25 toward the bottom piece facing portion 22 side.

  Further, in the first embodiment, the eaves cutting tool 1 includes a stopper 12 that restricts the insertion member 3 inserted from the insertion port 25 from coming out of the insertion port 25. A retaining protrusion 32 having a plurality of gentle slopes 321 provided in the insertion direction and steep slopes 322 provided between the inclined surfaces is formed on the surface facing the bottom piece facing portion 22 of the rear end portion 302 of the insertion member 3. The

  The gentle slope 321 is inclined so as to approach the bottom piece facing portion 22 as it goes from the front end side to the rear end side in the insertion direction. The angle formed with respect to the insertion direction is larger than the angle formed with the gentle inclined surface 321 with respect to the insertion direction so that the steep slope 322 is abruptly separated from the bottom piece facing portion 22 as it goes from the front end side to the rear end side in the insertion direction. Tilt. The retaining protrusion 32 and the end edge 251 of the insertion port 25 on the bottom piece facing portion 22 side constitute the stopper 12.

  Further, in the first embodiment, the eaves cutting tool 1 includes a release portion 13 that releases the restriction by the stopper 12. The rear end portion 303 of the insertion member 3 constitutes the release portion 13. On the surface of the rear end portion 303 of the insertion member 3 facing the bottom piece facing portion 22, a non-slip portion 33 made of unevenness is provided.

  A method for using the eaves cutter 1 will be described.

  First, the jig main body 2 is attached to a location where the eaves basket 4 is to be cut. The jig body 2 is deformed and inserted into the jig body 2, the side piece 421 on the ridge side is set along the side piece holding part 211 on the ridge side, and the side piece 422 on the eave side is set on the eave side. Along the piece holding part 212. Then, the ear part 43 is held by the grip part 23 by getting over the rear protruding piece 232 at the tip of the side piece holding part 21. Thus, the jig body 2 is attached to the eaves rod 4.

  The eaves 4 has dimensional variations due to manufacturing errors. For this reason, if the jig body 2 is designed so as to be along the entire outer surface of the eaves ridge 4, if the jig body 2 cannot be mounted without being covered with the eave ridge 4, the jig body 2 is attached to the eave ridge 4. If covered, the gap may be large and rattling may occur.

  In the first embodiment, the width of the side piece holding part 21 is longer than the width of the side piece 42, and the jig body 2 is formed to be larger than the eaves 4. For this reason, even if there is a variation in dimensions due to manufacturing errors in the eaves rod 4, it is difficult for the jig body 2 to be covered with the eaves rod 4.

  In addition, when the eaves rod 4 is simply put on the jig body 2, the jig body 2 does not rattle and cannot hold the eaves rod 4. For this reason, the insertion member 3 is inserted between the bottom piece 41 and the bottom piece facing part 22 to eliminate rattling of the eaves rod 4 in the jig body 2.

  Specifically, the distal end portion 301 of the insertion member 3 is inserted from the insertion port 25 so that the convex portion 31 of the insertion member 3 faces the bottom piece 41 side of the eaves rod 4. In the insertion member 3, the eave bar pressing portion (convex portion 31) presses the bottom piece 41 of the eave bar 4, the front end side jig main body pressing portion (front end portion 301) and the rear end side jig main body pressing portion (rear end). And the side portion 302) press the bottom piece facing portion 22. As a result, the bottom piece 41 and the bottom piece facing portion 22 are pushed in the direction in which the interval is increased by the insertion member 3, and there is no movement allowance of the eaves rod 4 within the jig body 2, and the eaves rod 4 does not rattle. .

  Moreover, since the retaining protrusion 32 is formed on the rear end portion 302 of the insertion member 3, even if a force in the direction opposite to the insertion direction is applied to the insertion member 3, the steep slope 322 is formed on the peripheral portion of the insertion port 25. Is caught and the insertion member 3 cannot be removed.

  In order to extract the insertion member 3, the hooking of the steep slope 322 to the peripheral edge of the insertion port 25 is released by pushing the release portion 13 toward the eaves 4 side. Thereby, the insertion member 3 can be extracted from the jig body 2.

  In the eaves rod cutting jig 1 according to the first embodiment, it is easy to fix the eaves rod 4 even if the eaves rod 4 has dimensional variations due to manufacturing errors.

  Moreover, the insertion member 3 can be comprised with a leaf | plate spring. Note that the insertion member 3 may have a general spring such as a coil spring that is not a leaf spring.

  Next, the eaves cutting tool 1 according to the second embodiment will be described with reference to FIGS. Note that the eaves-cutting jig 1 of the second embodiment is substantially the same as the eaves-cutting jig 1 of the first embodiment. For this reason, about the description which overlaps with 1st embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  The eaves hook 4 to be attached to the eaves cutting jig 1 is the same as the eaves hook 4 of the first embodiment shown in FIG.

  The jig main body 2 of the second embodiment is different from the jig main body 2 of the first embodiment that does not have such a connecting piece insertion groove 27 in that it has a connecting piece insertion groove 27 connected to the insertion port 25.

  As shown in FIG. 4, the insertion member 3 has a wedge portion 34. The wedge portion 34 has a small thickness on the front end portion 301 side in the insertion direction, and becomes thicker toward the rear end side. The insertion opening 25 of the jig main body 2 is formed in such a size that a portion where the thickness of the portion 302 on the rear end side of the wedge portion 34 is thick can be inserted. The wedge portion 34 may not have elasticity.

  On the surface of the wedge portion 34 facing the bottom piece facing portion 22, a retaining projection 37 having a gentle slope 371 provided in the insertion direction and a steep slope 372 continuous on the rear end side in the insertion direction of the slope is formed.

  Further, a retaining protrusion 26 having a plurality of gentle slopes 261 provided in the insertion direction and steep slopes 262 provided between the inclined surfaces is formed on the inner surface of the bottom piece facing portion 22.

  A retaining projection 37 provided on the wedge portion 34 and a retaining projection 26 provided on the bottom piece facing portion 22 constitute the stopper 12.

  A connecting piece 35 and a release piece 36 are provided on the surface of the wedge portion 34 facing the bottom piece facing portion 22. The connecting piece 35 is provided at the center in the width direction of the surface of the wedge portion 34 facing the bottom piece facing portion 22 with the insertion direction as the longitudinal direction. A release piece 36 is provided at the tip of the connecting piece 35. The release piece 36 has substantially the same shape as the front view and the size of the wedge portion 34.

  The width of the connecting piece insertion groove 27 of the jig body 2 is longer than the width of the connecting piece 35 and shorter than the width of the release piece 36 and the wedge portion 34. The insertion member 3 is formed of a synthetic resin in the first embodiment.

  Although the usage method of the eaves cutting jig 1 is demonstrated, a different point from 1st embodiment is mainly demonstrated.

  The distal end portion 301 of the insertion member 3 is inserted from the insertion port 25. When a portion having the same thickness as the interval between the bottom piece 41 and the bottom piece facing portion 22 is inserted, the wedge portion 34 pushes the bottom piece 41 and the bottom piece facing portion 22 in a direction in which the interval increases. Thereby, the movement allowance of the eaves rod 4 within the jig body 2 is eliminated, and the rattling of the eaves rod 4 is eliminated.

  Further, the steep slope 372 of the retaining projection 37 provided on the wedge portion 34 is caught by the steep slope 262 of the retaining projection 26 provided on the bottom piece facing portion 22, and the insertion member 3 does not come off.

  In order to extract the insertion member 3, the release portion 13 including the release piece 36 is pushed toward the eaves 4 side to release the catches of the steep slopes 372 and 262 of the retaining projections 37 and 26. Thereby, the insertion member 3 can be extracted from the jig body 2.

  Even in the eaves rod cutting jig 1 according to the second embodiment, it is easy to fix the eaves rod 4 even if the eaves rod 4 has dimensional variations due to manufacturing errors.

  Further, the insertion member 3 can be configured using the wedge portion 34.
