Description

  The present invention relates to an eaves rod support tool, and more particularly, it is possible to easily screw the eaves end with an electric screwdriver in spite of the formation of an overhanging piece for introducing rain falling on the support arm into the eaves rod. It relates to an eaves support that has good workability.

  Conventionally, various eaves supporters having different structures have been proposed. As one of them, an attachment portion, a support arm projecting from the attachment portion to the outdoor side, and an outdoor side of the support arm are provided. An eaves support comprising: an outdoor-side ear holding portion provided; an indoor-side ear holding portion provided indoors from the outdoor-side ear holding portion; and a plate body provided to project vertically and horizontally on the indoor side of the support arm. A tool is known (Patent Document 1).

  This eaves support is provided with a plate that protrudes vertically and horizontally on the indoor side of the support arm, so that rainwater increases, and the upper and lateral surfaces of the support arm flow in the indoor direction. However, it is described that rainwater cannot get over the plate body protruding vertically and horizontally, and therefore rainwater does not flow in the indoor direction and wet the eaves.

JP-A-9-317106

  However, if the plate body is provided on the indoor side of the support arm so as to protrude vertically and horizontally like the eaves support of Patent Document 1, the mounting portion of the eaves support is screwed with an electric screwdriver. When attaching to the eaves, the chuck part of the electric screwdriver interferes with the plate, making it difficult to fix the screws, resulting in a problem that workability is lowered.

  The present invention has been made under the circumstances described above, and the problem to be solved is that an eaves tip is used by using an electric screwdriver in spite of the formation of a protruding piece for introducing rainwater falling on the support arm into the eaves. It is an object of the present invention to provide an eaves bar support that can be easily screwed to a mounting plate and has good workability.

  In order to solve the above problems, the eaves rod support according to the present invention is provided with a mounting plate at the rear end of the support arm, and provided with a front ear support portion for supporting the front ear of the eaves rod at the front end of the support arm, An eaves rod support device provided with a rear ear support portion for supporting the rear ear of the eaves rod at the rear portion of the support arm or the front surface of the mounting plate, wherein the support arm has projecting pieces on both sides, and the projecting piece. Is characterized in that it protrudes forward or obliquely downward from the mounting plate and is tapered toward the front end.

  In the eaves support according to the present invention, it is preferable that the front end of the overhanging piece is located on both sides of the inclined portion of the support arm inclined obliquely forward and downward, and on the outer end of the overhanging piece. It is also preferable that a rising edge is formed.

  Like the eaves support of the present invention, the support arm has protruding pieces on both sides, and when this protruding piece protrudes forward or obliquely downward from the mounting plate, it falls on the support arm. Rainwater that flows down both sides and the front surface of the mounting plate is received by the overhanging piece, flows through the upper surface of the overhanging piece, and is introduced into the eaves from the front end of the rainwater. Can be prevented from falling. In addition, since this overhanging piece is tapered toward the front end, when the mounting plate is screwed to the eaves using an electric screwdriver, the chuck part of the electric screwdriver will not interfere with the overhanging piece, making it easy As the mounting plate can be screwed, workability is good.

  And, when the front end of the overhanging piece is located on both sides of the inclined portion of the support arm inclined obliquely downward in the forward direction, drainage performance of rainwater introduced from the front end of the overhanging piece into the eaves is improved. Furthermore, when the rising edge is formed at the outer end of the overhanging piece, there is an advantage that the rainwater can be surely introduced into the eaves from the front end of the overhanging piece without falling from the outer end of the overhanging piece.

  The eaves support according to the embodiment shown in FIGS. 1 to 7 is integrally formed of a thermoplastic synthetic resin such as polycarbonate, and has a rectangular shape at the rear end of the support arm 1 that is slightly bent as a whole. The mounting plate 2 is formed vertically. This support arm 1 is formed by forming a thick vertical rib portion 1c between a belt-like upper plate portion 1a and a lower plate portion 1b along the center line of the plate portions 1a and 1b. ), The upper plate portion 1a and the lower plate portion 1b approach each other as they approach the tip, and merge at the tip. And between the upper board part 1a and the lower board part 1b in the center part of the support arm 1, the horizontal rib part 1d for reinforcement which cross | intersects the vertical rib part 1c is formed.

  As shown in FIG. 4, a hook-shaped front ear support portion 3 that engages and supports the front ear 10 a of the eaves cage 10 from the lower inside is protruded upward at the tip of the support arm 1. On the lower surface of the distal end portion of the support arm 1, a convex portion 3 a that presses the step 10 b below the front ear 10 a is formed so that the front ear 10 a of the eaves is not lifted off from the front ear support portion 2. ing. A water thread locking projection 4 is projected upward on the upper surface of the upper plate portion 1a of the support arm 1 so that the water thread is engaged with the projection 4 when the eave hook support is attached to the eaves edge. It can be stopped and given a certain gradient.

  On the other hand, on the lower surface of the lower plate portion 1b at the rear portion of the support arm 1, a rear ear support portion 5 having an L-shaped side shape that engages and supports the rear ear 10c of the eaves rod 10 from the lower inside is formed. Ribs 6 are formed at the corners of the lower plate portion 1b and the mounting plate 2 on the rear side of the rear ear support portion 5 to serve as a reinforcement and prevent the rear ear 10c from coming off. In order to facilitate the insertion of the rear ear 10c of the eaves rod 10 into the rear ear support portion 5, the rib 6 is formed with a smooth concave curved surface from the upper front surface to the upper back surface.

  As shown in FIGS. 1 and 4, the mounting plate 2 is thickened at the top to increase the strength, and the support arm 1 projects forward from the center of the thickened top. . As shown in FIGS. 1 and 2, a total of three screw insertion holes 2a are formed at the upper left corner, upper right corner, and lower center of the mounting plate 2. From these screw insertion holes 2a, a total of three screw insertion holes 2a are formed. The mounting plate 2 can be attached to the eaves by screwing the screws into the nose cover plate 20 at the eaves. As shown in FIGS. 1 and 4, the upper surface of the mounting plate 2 is more than the rear end of the upper surface of the support arm 1 (the upper surface of the upper plate portion 1a) and the rear ends of the upper surfaces of the projecting pieces 7 and 7 described later. The rain water that has fallen on the upper surface of the support arm 1 and the rain water received by the overhanging pieces 7 and 7 do not get over the upper surface of the mounting plate 2 and wet the nose cover plate 20 at the eaves. It is like that.

  As shown in FIGS. 1 and 4, the lower surface of the mounting plate 2 is an inclined surface that is inclined forward and downward, thereby forming a draining edge 2 b at the lower end of the mounting plate 2. Further, as shown in FIG. 6, recesses 2c, 2d, 2d, 2e, and 2e for saving the amount of resin are formed on the rear surface of the mounting plate 2, but the upper left corner portion and the upper right corner portion are formed. The screw insertion holes 2a, 2a are formed in such a manner that the corners close to the screw insertion holes of the recesses 2d, 2d are recessed inward so that the respective screw insertion holes 2a, 2a are not cracked or broken. The distance between and is kept large.

  As shown in FIGS. 2 and 3, the major feature of this eaves support is that it has projecting pieces 7 and 7 that project from the both sides of the support arm 1 to the left and right. More specifically, the overhanging pieces 7 and 7 are inclined rearward and upward in the rear part of the support arm 1 from the middle of the lower plate part 1b to the rear end of the upper plate part 1a as shown in FIG. From the formed middle plate portion 1e, it is provided to project to the left and right outer sides, and as shown in FIGS. 1 to 4, the projecting pieces 7, 7 project obliquely forward and downward from the mounting plate 2, It is formed in a right-angled triangle shape that tapers toward the front end. There is no clear boundary line between the projecting piece 7 and the middle plate portion 1e, but as shown in FIG. 7A, there are portions that project to the left and right outside from both side ends of the upper plate portion 1a of the support arm 1. The projecting pieces 7 and 7, and the inner part of both sides of the upper plate part 1 a are the middle plate part 1 e.

  Since the overhanging pieces 7 and 7 serve to catch rainwater that falls on the support arm 1 and flows into the eave ridge 10, as shown in FIG. 4, as shown in FIG. It protrudes to the inside of the eaves wall 10 beyond. And the front end 7a of this overhanging piece 7 is located on both sides of the lower plate portion 1b of the inclined portion inclined forward and downward of the support arm 1, and the height of the front end 7a is the upper surface of the rear ear 10c of the eaves rod 10 Is almost the same height or lower. For this reason, rainwater can be reliably introduced into the interior of the eaves wall 10 from the front end of the overhanging piece 7, and good drainage performance can be exhibited. If necessary, a draining protrusion (not shown) may be provided on the front end 7a of the overhanging piece 7 so as to protrude downward, so that the draining performance can be further improved, and the overhanging piece 7 is supported by the front end 7a. It may be formed so as to protrude further downward from the lower plate portion 1b of the arm 1 to further improve the draining performance.

  The maximum overhanging dimension of the overhanging piece 7 (the overhanging dimension of the rear end of the overhanging piece 7) is not particularly limited, and is between the screw insertion holes 2a and 2a at the upper left corner and upper right corner of the mounting plate 2. However, considering the rainwater introduction function of the overhanging piece 7, the maximum overhanging dimension is 2 to 10 mm, especially 3 to 8 mm. It is preferable to set the degree.

  As shown in FIG. 3 and FIG. 4, the eaves hook support device having the above-described configuration applies the mounting plate 2 to the eaves nose cover plate 20 and uses an electric screwdriver 30 as shown in FIG. 40 is screwed into the nose cover plate 20 through the screw insertion hole 2a of the mounting plate 2. Then, the front ear 10a of the eaves rod 10 is supported by the front ear support portion 3 at the front end of the support arm 1, and the rear ear 10c of the eaves rod 10 is supported by the rear ear support portion 5 of the rear portion of the support arm 1. A saddle 10 is attached.

  Even if the mounting plate 2 is screwed using the electric screwdriver 30 as described above, the eaves support is formed in the shape of a right triangle whose rear projecting pieces 7 and 7 are tapered toward the front end. Therefore, as shown in FIG. 3, the chuck portion 30 a of the electric screwdriver 30 does not interfere with the protruding piece 7. Therefore, the screwing operation of the mounting plate 2 can be performed easily and efficiently, so that the workability is good. Moreover, in this eaves rod support tool, the rainwater that falls on the support arm 1 and flows down is received by the overhanging pieces 7, 7, flows on the upper surface of the overhanging pieces 7, 7, and reliably enters the inside of the eaves rod 10 from the front end 7 a. Therefore, rainwater can be prevented from falling to the ground from the rear part of the support arm 1, rainwater that has fallen on the support arm 1, and rainwater received by the overhanging pieces 7, 7. However, there is no worry of getting over the upper surface of the mounting plate 2 and wetting the nose cover plate 20.

  The eaves hook support of the embodiment shown in FIGS. 1 to 7 is provided with a rear ear support portion 5 on the lower surface of the rear portion of the support arm 1 (the lower surface of the lower plate portion 1b), but the embodiment shown in FIG. Like the eaves hook support of the form, while providing the rear ear support part 50 which engages and supports the rear ear 10c of the eaves bowl 10 from the outer lower side on the front surface of the mounting plate 2, the rear ear 10c is the rear ear support part 50. The protruding piece 51 for preventing it from coming off may be configured to protrude downward from the rear lower surface of the support arm 1 (the lower surface of the lower plate portion 1b). In order to make it easier to insert the rear ear 10c of the eaves rod 10 into the rear ear support portion 50, the protruding piece 51 is formed with a smooth concave curved surface from the rear surface to the upper back surface.

  8 is similar to that of the eaves bar support of FIGS. 1 to 7 described above, and therefore, the same reference numerals are assigned to the corresponding members in FIG. Description is omitted.

  The extension piece 7 of the eaves support according to the embodiment shown in FIGS. 1 to 7 is formed so as to protrude from the middle plate portion 1e of the rear portion of the support arm 1 to the left and right sides. As shown in FIG. The rear portion of the arm 1 may be formed so as to project outward from the left and right sides. Alternatively, as illustrated in FIGS. 10 and 11, the support arm 1 may be formed so as to project outward from the left and right sides. . In short, the overhanging piece 7 may be formed so as to protrude from both sides of the rear portion of the support arm 1.

  1 to 7 and the overhanging piece 7 shown in FIGS. 9 and 10 are each formed in a tapered shape by protruding forward and obliquely downward from the mounting plate 2. However, it may be formed in a tapered shape by projecting forward (horizontal front) from the mounting plate 2 as in the overhanging piece 7 shown in FIG.

  Furthermore, the protruding piece 7 of the eaves support shown in FIGS. 1 to 7 and the protruding piece 7 shown in FIGS. 9 and 10 are all formed in a right-angled triangle shape that tapers toward the front end. 11 may be formed in a trapezoidal shape that tapers toward the front end, and the outer side (outer end) of the right-angled triangular or trapezoidal protruding piece 7 is indented inward. It is good also as a protruding piece of the shape. In short, the shape of the overhanging piece 7 only needs to be a tapered shape that can receive rainwater and can be dropped and introduced into the eaves from the front end and does not interfere with the electric screwdriver. Even if the shape is a taper, a taper-shaped projecting piece whose outer side is curved outward is not preferable because the curved outer side may interfere with the chuck portion of the electric screwdriver.

  The rear end of the overhanging piece 7 may be the same height as the rear end of the upper surface of the support arm 1 as in the embodiment of FIGS. 1 to 7 and the embodiment of FIG. As in the form, it may be lower than the rear end of the upper surface of the support arm 1. When the rear end of the overhanging piece 7 is lowered as in the latter case, not only the rainwater flowing from the rear part of the support arm 1 but also the rainwater flowing down the front surface of the mounting plate 2 is received by the overhanging piece 7 and introduced into the eaves 10. There are advantages you can do.

  Further, as shown in FIG. 11, it is preferable to form a rising edge 7 b at the outer end (outer side) of the projecting piece 7. When such a rising edge 7b is formed, there is an advantage that rainwater can be reliably introduced from the front end 7a of the overhanging piece 7 into the eaves without the rainwater falling from the outer end of the overhanging piece 7. The height of the rising edge 7a is about 1 to 10 mm, preferably 2 to 5 mm.
