Hereinafter, the best mode for carrying out the present invention will be described based on an embodiment shown in the drawings.
FIG. 1 shows an example of an eaves-cutting jig main body according to the present invention attached to an eaves, where (a) is a front view, (b) is a plan view, and (c) is a left side view.
In the figure, 1 is an eaves cutting jig and 2 is an eaves cutting jig. The eaves cutting tool 1 includes a main body portion 11 having an inner peripheral surface that fits to the outer peripheral surface of the eaves rod 2 and a pair of ears that hold the ear portions of the eaves rod 11 provided at both upper ends of the main body portion 11. The gripping parts 12 and 13, the flange 16 formed along the outer side of at least one side edge of the main body 11, and an elastic clip tool 18 separately illustrated.

  The eaves 2 is square in cross section and is provided with a hollow portion in the longitudinal direction in the bottom corner portion 21 and both ear portions 22 and 23 in order to give rigidity, and one ear portion 22 is inward along the upper edge. A protruding strip 24 protruding outward and a protruding strip 25 protruding outward are formed.

  A concave groove 14 is formed in the ear gripping portion 12 of the eaves rod cutting jig main body 11 in order to fit and grip the outward protrusion 25 of the ear portion 22 of the eaves rod 2. By forming the groove 14, an outward projecting strip 15 is formed along the upper end edge of the ear gripping portion 12.

The flange piece 16 is a guide contact surface of a cutting tool such as a saw, an electric circular saw, or a chain saw, and is a flange that is bent outward along one side edge of the main body portion 11. One ear gripping portion 12 of the hook piece 16 is extended to the inside of the eaves hook 1 to form a knob 17.
Reference numeral 19 denotes a reinforcing rib for reinforcing the flange piece 16 bent along the side edge of the main body 11.

  As an inner shape of the main body portion 11 of the eaves rod cutting jig 1, it is only necessary to have an inner peripheral surface that fits with the outer peripheral surface of the eaves rod 2. That is, there is no particular limitation as long as it is a shape that can be held on the outside of the eaves bowl 2 without rattling when the eaves bowl cutting jig 1 is attached to the outside of the eaves bowl 2. If the gap between the inner surface of the main body 11 and the outer surface of the eaves 2 is too large when attached to the outside of the eaves 2, it becomes difficult to hold the main body 11 on the outer side of the eaves 2. Since the displacement of the direction is likely to occur, the gap between the inner surface of the main body 11 and the outer surface of the eaves 2 is preferably 0.1 to 1.2 mm.

  The elastic clip tool 18 is formed by bending a predetermined metal piece having spring elasticity, and holds the ear portion 22 of the eaves 2 and the ear grip portion 12 of the jig 1 in a state where the internal space is pushed and expanded. If it is. For example, as shown in FIG. 2, a main body 18a having a substantially U-shaped cross section has a hook piece 18b formed on one opening edge and a knob 18c formed on the other opening edge. Alternatively, like a double clip used for binding a plurality of documents, the clip may be widened and pinched by pinching a knob.

  Then, in order to cut the eaves ridge 2 using the eave ridge cutting jig 1 of the present invention, the eave ridge 2 is positioned so that the end face of the ridge piece 16 comes to the position where the eave ridge 2 is to be cut. Attach the scissors cutting jig body 11. In order to attach the main body part 11, the ear gripping part 13 is gripped by one ear part, the main body part 11 is covered along the outer peripheral surface of the eaves bowl 2, and the eaves hook 14 is placed in the groove 14 of the ear gripping part 12. The ear grasping portion 12 is grasped by the other ear portion 22 so that the protruding protrusion 25 outward of the second ear portion 22 is fitted. When the ear gripping part 12 is gripped by the other ear part 22, it can be easily attached by gripping the knob 17 of the collar piece 16 and fitting the jig 1 so as to expand it.

Then, using the elastic clip tool 18 shown in FIG. 2, for example, the ear portion 22 of the eaves ridge is attached to one ear grip portion 12 of the eaves ridge 2 in which the main body portion 11 of the eaves ridge cutting jig 1 is fitted. In the gripped state, the elastic clip device 18 holds the ear portion 22.
In order to hold it with the elastic clip 18, as shown in FIG. 3, the hook piece 18b formed on one opening edge of the elastic clip device 18 is hooked on the protruding strip 24 formed inside the ear portion of the eaves rod 2. Then, the knob 18c formed on the other opening edge is picked and the main body 18a of the clip tool 18 is expanded and slid along the protrusion 15 of the jig 1, and the knob 18c is fitted to the lower side of the protrusion 15. That's fine.

  In the elastic clip tool 18, the hook piece 18b is hooked on the protrusion 24 of the eaves-ear part, and the knob piece 18c is hooked on the lower side of the protrusion 15 of the main body 11, so that the elastic clip tool 18 is firmly held. . In addition, since the knob 18c can be fitted while sliding, even the strong elastic clip device 18 can be easily attached.

Since the eaves rod cutting jig 1 attached in this way is firmly fixed to the eaves rod 2, the eaves rod 2 is cut diagonally along the rod piece 16 using a saw, an electric circular saw, a chain saw or the like. Can be cut at right angles to the longitudinal direction.
When attaching the eaves cutting jig 1 to the eaves eaves 2, it is easy to perform the installation work by placing it on the work table with the opening of the eaves eaves 2 facing upward, It is preferable to turn it over and cut from the bottom side because it is possible to start cutting stably.
Since the eaves 2 is cut at a right angle to the longitudinal direction no matter where it is cut, if the cut eaves are brought into contact with each other, they fit together and do not impair the beauty.

  When the cutting of the eaves 2 is completed, the eaves cutting jig 1 is removed, but it can be removed while sliding the elastic clip tool 18 so as to spread the picking piece 18c. Since the knob 17 can be removed by pulling and pushing it, it can be easily removed.

In addition, in the said Example, when the ear | edge part 23 and the ear | edge-gripping part 13 of the eaves 2 are clamped by the double clip also on the ear holding part 13 side, the eaves-cutting jig main-body part 11 will be more firmly attached to the eaves 2. Can be attached.
Moreover, in the said Example, the hollow ear | edge part which protrudes only in the upper end inward of the eaves rod 2 may be provided, without providing the protrusion 15 in the outer surface of both ears of the eaves rod 2. . In this case, both ears of the eaves basket 2 may be sandwiched between the ear gripping part of the jig body 11 and the double clip.

  Furthermore, in the present invention, for example, the eaves ridge cutting jig 1 is attached to the eaves ridge 2, and once the marking line 16 is drawn on the outer peripheral surface of the eave ridge 2, It is also possible to remove and cut along the marking line, which is particularly suitable when using an electric circular saw or a chain saw. In the eaves-cutting jig 1 of the present invention, since it does not move even when a marking line is drawn, a marking line perpendicular to the longitudinal direction can be drawn.

An example of the eaves-cutting jig main body part of this invention is shown in the state attached to the eaves, (a) is a front view, (b) is a top view, (c) is a left view. An example of an elastic clip tool is shown, (a) is a front view, and (b) is a bottom view. It is the elements on larger scale which show an example of the state which attaches an elastic clip tool to an ear grasping part, (a) is a front view showing the state in the middle of attachment, and (b) is a front view showing the state where attachment was completed.
