Description

  The present invention relates to an eaves cutting aid that is attached to a part of the eaves in the longitudinal direction and assists the cutting of the eaves with a saw blade.

  For example, as shown in FIG. 4, the conventional eaves rod cutting assisting tool has an inner surface that is shaped along the outer surface of the eaves rod 2, and a rod orthogonal to the longitudinal direction of the eaves rod 2 as a guide portion at both ends in the width direction. A shaped portion 41 is provided. When cutting the eaves 2 using the eaves cutting aid 40, as shown in FIG. 4, the eaves cutting aid 40 is fitted on the outer surface of the eaves 2 in the downward opening state, and the eaves cutting is performed. Both ends in the circumferential direction of the auxiliary tool 40 are placed on the floor or the like, and a saw blade such as a moving saw is moved using the hook-like portion 41 of the eaves cutting aid 40 as a guide, thereby moving the eave hook 2 to the bottom wall 2b. Cut from the side to a predetermined dimension.

  However, since the eaves ridge cutting auxiliary tool 40 shown in FIG. 4 holds only the outer surface side of the eave ridge 2 and keeps the shape of the eave ridge 2 only from the outer surface side, the eave ridge 2 is cut when the eave ridge 2 is cut from the bottom wall side. The scissors 2 were pushed inward by the saw blade and easily bent, and it was difficult to accurately cut the eaves scissors 2 along the scissors 41. Further, when the saw blade is moved along the hook-shaped portions 41 provided at both ends in the width direction of the eaves rod cutting aid 40, only one side of the saw blade of the eaves rod 2 is held by the eaves rod cutting aid 40. Therefore, the other side sandwiching the saw blade not held by the eaves rod cutting aid 40 is lowered by its own weight, which is also a factor that makes it difficult to cut the eaves 2.

Further, for example, an eaves cutting aid disclosed in Patent Document 1 includes an outer surface fitting member that has an inner surface along the outer surface of the eaves and is detachably fitted to the outer surface of the eaves, and the outer surface fitting A slit part serving as a guide for the saw blade is provided in the member in the circumferential direction, and this part holds the both sides of the saw blade in the eave bar by the outer surface fitting member, while passing the eave bar through the slit part. It can be cut. However, since the eave ridge cutting aid of this patent document 1 is also an outer surface fitting member and maintains the shape of the eave ridge only from the outer surface side, the eave ridge is easily deformed by being pushed inward by a saw blade during cutting. The scissors could not be cut accurately and easily.

  As shown in FIG. 1, hook-shaped portions 19 projecting outward are provided over the entire length in the circumferential direction at both ends in the width direction of the outer surface fitting member 13. In addition, an outer slit portion 20 extending in the circumferential direction of the outer surface fitting member 13 is formed in the center of the outer surface fitting member 13 in the width direction. The outer surface in the width direction of each hook-shaped portion 19, 19 and the both inner surfaces in the width direction of the outer slit portion 20 are orthogonal to the width direction of the outer surface fitting member 13. The slit portion 20 serves as a guide portion 22 that guides the movement of a saw blade (not shown) when cutting the eaves rod 2. Here, the outer slit portion 20 is formed from the bottom surface portion 13b of the outer surface fitting member 13 to a position exceeding both the support portions 42 and 43 via both side surface portions 13a and 13c. In particular, the outer slit portion 20 of the present example is formed over the entire length of the outer surface fitting member 13 in the circumferential direction. It consists of outer divided bodies 21, 21.

  As shown in FIG. 2, the inner surface fitting member 14 has one end portion in the circumferential direction (that is, the distal end portion of a side surface portion 14 c described later) at the distal end portion of the building side support piece portion 17 of the outer surface fitted member 13 in the direction indicated by the arrow A.

A piece-like outdoor side locking portion 24 projects inward from the tip of the side surface portion 14a, and the base end portion of the outdoor side locking portion 24 faces away from the bottom surface portion 14b. The outdoor side fitting part 25 protrudes. Further, at a position that is less than the front end of the side surface portion 14c, the portion located on the front end side is bent so as to be located on the inner side than the base portion side.

  An inner slit portion 26 is formed over the entire length in the circumferential direction at the center in the width direction, which is a portion corresponding to the outer slit portion 20 of the inner surface fitting member 14, that is, the inner surface fitting member 14 of this example is an inner side. It consists of two independent inner divided bodies 27, 27 divided through a slit portion 26. The inner slit portion 26 overlaps the outer slit portion 20 when viewed from the outside in a state where the outer surface fitting member 13 is fitted on the outer surface of the eaves rod 2 and the inner surface fitting member 14 is fitted on the inner surface of the eaves rod 2. In other words, the outer slit portion 20 of the outer surface fitting member 13 is provided at a portion that does not overlap with the inner surface fitting member 14. Here, each inner divided body 27, 27 constituting the inner surface fitting member 14 is rotatably connected to each outer divided body 21, 21 constituting the outer surface fitted member 13 via a different pivot portion 28. Thereby, the inner surface fitting member 14 is rotatable with respect to the outer surface fitting member 13. In addition, each pivot part 28 which connects the inner side divided body 27 and the outer side divided body 21 does not exist in the site | part corresponding to the inner side slit part 26, Thereby, the inner side slit part of the inner surface fitting member 14 at the time of the cutting | disconnection of the eaves 2 The saw blade that has passed through 26 is prevented from hitting each pivot 28.

  The distal end portion of the side surface portion 13c located at one end in the circumferential direction of the outer surface fitting member 13 is connected to one end portion of the leg member 12 so as to be rotatable in the direction indicated by arrow B. Standing piece portions 29 and 29 are erected on both ends of the leg member 12 in the width direction.

Used as a member for guiding the movement of the saw blade.

  Both end portions of each of the standing piece portions 29 and 29 are connected by connecting piece portions 30 and 31. Both side end portions of each of the standing piece portions 29 and 29 protrude from the intermediate portion toward the outer surface fitted member 13, thereby forming continuous portions 32 and 33 at both ends in the width direction of both side end portions of the leg member 12. is doing. The spaces 34, 35 formed between the continuous portions 32, 32 provided at one side end of the leg member 12 and between the continuous portions 33, 33 provided at the other side end are the leg members 12. Are provided at positions overlapping the outer slit portion 20 and the inner slit portion 26 in the width direction. These cavities 34 and 35 serve as cavities for escaping the saw blade, and when the saw blades that have passed through the outer slit portion 20 and the inner slit portion 26 at the time of cutting the eave basket 2 hit the leg member 12 due to these cavities. I am trying not to.

  The outer divided bodies 21, 21 are rotatably connected to the distal end portions of the continuous portions 33, 33 via a rotation shaft portion 36, so that the outer surface fitting member 13 is connected to the leg member 12. And can be rotated freely. Each rotating shaft part 36, 36 is located between the distal end parts of the projecting parts 33, 33 and is connected to each outer divided body 21, 21 at this position, but each rotating shaft part 36 has a width of the auxiliary tool 1. In the direction, it does not exist at the position overlapping with the outer slit portion 20 and the inner slit portion 26, so that the saw blade that has passed through the outer slit portion 20 does not hit each rotating shaft portion 36 when the eaves 2 is cut. ing. Further, the leading end surfaces of the continuous portions 32 and 32 are notched into a triangular shape that is convex toward the base side, thereby forming a locked portion 37.

  When cutting the eaves basket 2 using the auxiliary tool 1, first, the auxiliary tool 1 is attached to a part in the longitudinal direction of the eaves basket 2. The auxiliary tool 1 is attached in a state in which the leg member 12 and the inner surface fitting member 14 are opened with respect to the outer surface fitting member 13, and the outer surface fitting member 13 is attached to the outer surface of the eaves 2 including the ear portions 4 and 5. Fit from the outside. In a state where the outer surface fitting member 13 is fitted to the eaves cage 2, the inner surfaces of the bottom surface portion 13b, the side surface portion 13a, and the side surface portion 13c are the bottom wall portion 2b, the side wall portion 2a, and the side wall portion 2c of the eaves cage 2. Along each of the outer surfaces, the protruding portions 15 are fitted into the outer surfaces of the bent portions 3 of the eaves 2. The outdoor side support piece 16 is locked to the outdoor side supported part 10 of the ear part 4 of the eaves bowl 2, and in this state, the outdoor side support part 42 hits the outdoor side supported part 10 and the side wall part 2 a of the eaves bowl 2. The building side support part 43 hits the building side supported part 11 and supports the tip part of the side wall part 2c of the eaves wall 2.

  Next, the inner surface fitting member 14 in an open state with respect to the outer surface fitting member 13 is rotated and closed in a direction approaching the inner surface of the outer surface fitting member 13, thereby closing the inner surface fitting member 14. It is inserted from the inside into the inner surface of the eaves bowl 2 on which 13 is fitted. When the inner surface fitting member 14 is fitted in the eaves bowl 2, the outer surfaces of the bottom surface part 14b, the side surface part 14a, and the side surface part 14c are on the bottom wall part 2b, the side wall part 2a, and the side wall part 2c of the eaves bowl 2. Along each of them, the bent piece 23 is fitted into the inner surface of the bent portion 3 of the eaves 2. Further, the outdoor side engaging portion 25 is engaged with the fitted portion 8 and the outer surface of the outdoor side engaging portion 24 is applied to the ear portion 4 so that the outdoor side engaging portion 24 is engaged with the ear portion 4, and the side surface The ear portion 5 is sandwiched between the tip portion located inward of the base portion of the portion 14c and the tip portion of the side surface portion 13c of the outer surface fitting member 13 facing the same portion.

  Next, the leg member 12 in an open state with respect to the outer surface fitting member 13 is rotated and closed in a direction in which the distal end on the locked portion 37 side approaches the distal end of the side surface portion 13a of the outer surface fitting member 13, As a result, the locking portion 18 of the outer surface fitting member 13 is fitted and locked to the respective locking portions 37, 37 provided at the tip of the leg member 12, and the attachment of the auxiliary tool 1 to the eaves 2 is completed. .

  Then, the eaves ridge 2 attached with the auxiliary tool 1 is set in a downward opening state that is upside down from that during construction, and the lower surface of the leg member 12 is placed on the floor surface with the leg member 12 of the auxiliary tool 1 facing down. The eaves rod 2 placed in the above-mentioned state and held in the downward opening state held by the auxiliary tool 1 is cut with a saw blade from the bottom wall 2b side (upper side).

  When the eaves ridge 2 is cut with a saw blade, the saw blade can be moved along the outer slit portion 20 and each ridge portion 19 extending in a direction orthogonal to the longitudinal direction of the eave ridge 2 of the auxiliary tool 1. The eaves bowl 2 can be cut in a direction orthogonal to the longitudinal direction of the eaves bowl 2.

  In the auxiliary tool 1 of this example, the outer surface fitting member 13 is fitted on the outer surface of the eaves rod 2 and the inner surface fitting member 14 is fitted on the inner surface of the eaves rod 2, thereby Since the fitting member 13 and the inner surface fitting member 14 can be clamped from inside and outside, the outer surface fitted member 13 can retain the shape of the eaves 2 from the outer surface side, and the inner surface fitting member 14 can retain the shape of the eaves 2 from the inner surface side. Therefore, when the eaves ridge 2 is cut from the bottom wall portion 2b with the saw blade as described above, the eave ridge 2 can be prevented from being bent inward by the saw blade, and the eave ridge 2 can be prevented from being bent. Can be cut accurately and easily.

  Further, in this case, since either the outer slit portion 20 or the hook-shaped portion 19 can be selected and used as a guide for the saw blade, when the hook-shaped portion 19 is used as a guide, the extreme end in the longitudinal direction of the eaves rod 2 When the outer slit portion 20 is used as a guide, both the outer divided members 21 of the outer surface fitting member 13 and the inner divided members 27 of the inner surface fitting member 14 are used as saw blades in the eaves basket 2. Can be cut while holding both sides. Further, since the outer slit portion 20 is formed from the bottom surface portion 13b of the outer surface fitting member 13 to a position exceeding both the support portions 42 and 43 via the both side surface portions 13a and 13c, the outer slit portion 20 is used as a guide of a saw blade. When doing, it can cut completely by one cutting operation, without removing auxiliary tool 1 from eaves rod 2. Further, when the eaves 2 is cut, the locking portions 18 formed at the front end of the outer surface fitting member 13 can be locked to the respective locking portions 37 provided at the front end of the leg member 12, so that the outer surface fitting member 13 Both ends in the circumferential direction that are easy to move away from each other can be held by the leg members 12, and the eaves 2 can be further shaped by the outer surface fitting members 13.

  In this example, the outer slit portion 20 is provided over the entire length of the outer surface fitting member 13 in the circumferential direction. However, for example, as shown in FIG. You may provide only in a part in the circumferential direction, such as forming in the remaining range a.
