  However, in the conventional vertical shaft shown in the figure, the connecting member j includes the first sandwiching plate 4 and the second sandwiching plate 5 provided with a plurality of bolt holes 4a and 5a, the connecting piece 3 connecting them, and the first It has a complicated structure consisting of a number of components such as a plurality of bolts b1 and b2 attached to the sandwiching plate 4 and sandwiching pieces 7a and 7a for sandwiching the support portion 1. Therefore, the connecting member j is assembled to the support member s. In addition to the plurality of nuts 8, in addition to the plurality of nuts 8, a large number of holes, screw parts, plate material edges, fixing rivets, etc. of the component parts are exposed in an uneven state. Therefore, the cover c covering the connecting member j and the guide rail 9 for mounting the same are indispensable as components, and as a result, the number of parts increases as a whole, and the cost increases accordingly. There was a problem.

  Moreover, according to the conventional illustrated vertical shaft, when the connecting member j is attached to the support arm 2 of the support member s, the connecting member j is not simply fastened with bolts and nuts to fasten the connecting member j to the support arm 2, but the installation site. Then, the connecting member j in a flatly expanded state is once arranged on the support arm 2, and then the connecting piece 3 is bent to sandwich the support arm 2 between the first and second sandwiching plates 4, 5, and the bolt b 1. After b2 is passed through the bolt hole 5a of the second sandwiching plate 5, the connection piece 6 is folded back, and then the nut 8 is tightened to the screw tip of the bolts b1 and b2 to fasten the connecting member j to the support member s. Further, since the connecting member j needs to be attached to the support arm 2 while assembling the connecting member j through a number of processes such as engaging the cover c with the guide rail 9 and covering the connecting member j, the vertical member body t is connected with the connecting member j. The Support member s linked is very troublesome series of operations for attaching to a wall w and the, resulting in a problem of poor mounting workability time and effort it takes to.

  In addition, in the conventional vertical shaft shown in the figure, the support arm 2 is sandwiched between the first and second sandwiching plates 4 and 5 of the connecting member j by tightening the nut 8 into the bolts b1 and b2, and based on the sandwiching force. Thus, the convex support portion 1 of the vertical rod main body t is sandwiched between the both sides by the pieces 7a and 7a. However, since it is held so as to grasp one point of the convex support portion 1, the wall w of the vertical rod main body t There is a risk of lack of mounting strength. Therefore, in the conventional vertical rod, at each fixed position, two support arms 2 of the support member s protrude upward and downward in the height direction with respect to the connection member j, while the connection member j has a vertically long rectangular shape in the figure. The attachment strength is reinforced by increasing the length of the sandwiching portion 7 that is formed to hold the support portion 1 with the sandwiching pieces 7a and 7a. However, this increases the number of parts by the number of anchors a and support arms 2 of the support member s, and increases the cost of the connecting member s.

  An object of the present invention is to provide an inexpensive downspout with a simple structure and a reduced number of parts, which can be easily attached to a wall to improve the mounting workability and increase the mounting strength of the downspout body.

  Therefore, in order to achieve the above-described object of the present invention, the invention described in claim 1 includes, for example, the vertical main body 10 attached to the wall W of the building and the height of the wall W as shown in the following illustrated embodiment.

And

  According to the vertical shaft according to the first aspect of the present invention, when the connecting tool is connected to the support tool and fastened, the action point portions are respectively engaged with the engaging grooves while the fulcrum portions of the lever members are abutted against each other. Since the force point part that is engaged and clamped with the support tool is tightened by the fastening means, the principle of the lever works, that is, when the fastening force by the fastening means is applied to the force point part far from the fulcrum part, it is close to the fulcrum part The action point part pivots in the direction to open and open the connecting rib with the fulcrum part as a fulcrum, and the tightening force by the fastening means acts as a large pressing force at the action point part. Therefore, the action point part is connected to the connecting rib and the rib. The outer peripheral surface is strongly pressed and is engaged with the engaging groove in the strong pressure state, whereby the vertical hook body is connected to the support tool and firmly fastened by the connecting tool. Mounting strength can be increased.

  Therefore, in the downspout according to the first aspect of the present invention, since it is not necessary to provide extra means for reinforcing the mounting strength, only one support tool is provided on the wall at each fixed position. On the other hand, it is sufficient that the coupling tool is composed of a pair of lever members sized so as to sandwich one support tool between them, and the number of parts is greatly reduced by the number that unnecessary parts are unnecessary, and the cost is also reduced. Can be suppressed. Moreover, according to the downspout of the present invention, the connector is an extremely simple and simple structure composed of only a pair of insulator members, and is not an uneven and complicated structure that hinders the aesthetics of the building.

  Furthermore, in the vertical hook according to the invention described in claim 1, when the connecting tool is constituted by a separate lever member and the vertical hook main body is connected to the supporting tool by the connecting tool, the lever is sandwiched between the supporting tools. In order to fasten the force point portion of the member with the fastening means and fasten it to the support tool, the support tool of the vertical hook body may be of any shape and structure that can be fastened by being sandwiched between separate insulator members, for example, a concrete wall Various types of support can be used, such as a support that is only fixed to a plate wall, and is not limited to the dedicated support that embeds the anchor in the wall. There is no.

  According to the vertical shaft according to the second aspect of the present invention, the connecting ribs of the vertical rod main body project obliquely from the outer peripheral surface in a direction facing each other, and the groove groove gradually tapers toward the back side. On the other hand, in order to form the action point portion of the lever member in a tapered convex shape according to the groove shape of the engagement groove, the action point portion is used as the engagement groove with the fulcrum portions abutting each other. When the force point portion that is engaged and the support tool is sandwiched therebetween is tightened by the fastening means, the action point portion is engaged with the engagement groove in a state where the action point portion is firmly bite into the engagement groove. Firmly attached to the wall. Therefore, the lever principle works effectively, and the attachment strength to the wall of the vertical rod main body can be further increased. Moreover, since the action point part of the lever member is configured to engage the engagement groove so as to be slidable in the hook length direction, when connecting the vertical hook body to the support tool with the connecting tool, for example, between the force point parts When setting the coupling tool across the support tool, it is possible to easily align the position by adjusting the engagement height position by shifting in the hook length direction, for example, by connecting the bolt insertion hole of the fastening means.

  In the vertical shaft according to the invention described in claim 3, the connector is formed so that the fulcrum portion of the lever member is curved in a semicircular shape and is convex toward one side in the thickness direction of the force point portion. In addition to functioning as a fulcrum of the original lever, an auxiliary function can also be exhibited as a string winding portion that wraps a string member such as a rubber band and connects the two lever members. Therefore, when the auxiliary function of the fulcrum part is utilized and the action point part of the pair of lever members is engaged with the engaging groove, the cord member is wound around the fulcrum part and the lever member is connected, and then the fulcrum part is supported as a fulcrum. As a result, the action point parts at the tips are moved closer to each other, and the distance between the action point parts is made narrower than that between the connecting ribs. The operating point can be easily engaged with the engaging groove. As a result, the working efficiency is increased by the amount that the operating point is not required to be engaged with the engaging groove one by one, and the mounting workability is improved. be able to.

  According to the vertical scissors according to the invention of claim 4, the fulcrum part of the lever member is formed in a convex shape with a cross-sectional shape, and the action point part is formed in a tapered convex shape with a cross-sectional shoe shape at the tip of the fulcrum part. By doing so, the principle of the lever by a coupling tool can be worked effectively.

  According to the vertical scissors according to the fifth aspect of the present invention, the distal end portion of the lever member is formed in a cross-sectional boot shape, the heel portion of the distal end portion is formed as a convex fulcrum portion, and the toe side is tapered. By forming it as a convex action point portion, the principle of the lever by the connecting tool can be effectively exerted.

  Hereinafter, the best mode of the present invention will be described with reference to the drawings.

The support arm 30 is a stainless steel wing plate metal fitting, and includes a screw shaft portion 30a to be screwed into the screw hole 12a of the anchor 12, and a wing plate portion 30b extending in the axial direction from the end portion of the screw shaft portion 30a. In the wing plate portion 30b, two bolt insertion holes 13 made of long holes are arranged in series in the longitudinal direction.

  The anchor 12 is a grip anchor that is embedded by being driven into mounting holes formed one by one at intervals in the height direction of the wall W to which the vertical rod main body 10 is attached. The support 15 is fixed to the wall W in such a manner that the screw shaft portion 30a of the support arm 30 is screwed into the screw hole 12a of the anchor 12 and the wing plate portion 30b stands vertically and protrudes horizontally from the wall W. .

  The connecting tool 20 is a means for connecting the vertical scissors main body 10 to the support tool 15 using the lever principle, and is provided with a pair of lever members 35 and 35 having the same shape. That is, as shown in FIGS. 2, 3 and 4, the lever members 35 and 35 are each formed in a thick plate shape made of aluminum, for example, and fastened by the bolt 25a and the nut 25b of the fastening means 25. A longitudinal force point portion 35a on the proximal end side, an action point portion 35b at the distal end away from the force point portion 35a and engaged with the engagement groove 11 of the vertical rod main body 10, and a fulcrum portion formed near the action point portion 35b It is formed integrally with 35c.

  The force point portion 35a corresponds to the length of the wing plate portion 30b of the support arm 30, has a slightly long rectangular shape and a thick plate shape with a thickness of about 5 mm, and has a round hole insertion hole 14 in the longitudinal direction. One side by side. In the illustrated example, the lever members 35 and 35 are formed such that a fulcrum part 35c and an action point part 35b that extend in order from the tip side of the force point part 35a are formed one step thinner than the force point part 35a, and the fulcrum part 35c is curved in a semicircular shape. Then, the force point portion 35a is formed in a convex shape toward one side in the thickness direction, and the action point portion 35b is further extended in a convex shape from the tip of the fulcrum portion 35c to the other side in the thickness direction of the force point portion 35a. Formed. The action point portion 35b of the illustrated example is formed in a tapered convex shape according to the groove shape of the engagement groove 11 of the vertical rod main body 10, and is in close contact with the engagement grooves 11 and 11 while being engaged in the longitudinal direction of the hook. Can be slidably engaged.

  Next, a construction method for attaching the vertical gutter main body 10 to the wall W in the vertical gutter T having the above configuration will be described. First, mounting holes are drilled one by one at predetermined positions at intervals in the height direction of the wall W of the building to which the vertical gutter body 10 is attached, and anchors 12 are embedded in the mounting holes. By screwing the screw shaft portion 30a into the support arm 30 and screwing the support arm 30 to the anchor 12, the support 15 is fixed to the wall W, and the wing plate portion 30b is erected as shown in FIG. Then, the support arm 30 is set on the wall W in a state of being projected horizontally.

  Next, after placing the downboard main body 10 with the connecting ribs 10b and 10b facing the support arm 30 of the support member 15, as shown in FIGS. 5 (B) and 6, on one side of the support arm 30. The action point part 35 b of the lever member 35 is inserted into the engagement groove 11 on one side and engaged, and the force point part 35 a is overlapped with the blade part 30 b of the support arm 30. Then, as shown in FIGS. 5C and 7, on the other side of the support arm 30, the action point portions 35 b of the pair of lever members 35 are inserted into the engagement grooves 11 on the other side and engaged with each other. With the convex side of the fulcrum portions 35c and 35c in contact with each other, the connecting plate 20 is set in a sandwich state in which the wing plate portion 30b of the support arm 30 is sandwiched between the force point portions 35a and 35a and the bolt insertion holes 13 and 14 are communicated. To do. At that time, the lever members 35 and 35 are engaged with the engaging grooves 11 and 11 so that the action point portions 35b and 35b are slidable in the hook length direction. The position of the engagement height can be adjusted by shifting the position so that the bolt insertion holes 13 and 14 can communicate with each other easily.

  Thereafter, as shown in FIG. 5D and FIG. 8, the connecting tool 20 is fastened to the support tool 15 using the bolts 25 a and the nuts 25 b of the fastening means 25 in the vertical shaft T shown in the figure. That is, after the bolt 25a is passed through the bolt insertion holes 13 and 14, the nut 25b is tightened into the threaded portion of the bolt 25a, and as shown in FIGS. Is fastened to the support arm 30 of the support 15. As described above, when the coupling tool 20 is fastened to the support tool 15 at each predetermined position in the height direction of the wall W, the vertical gutter main body 10 is attached to the wall W of the building, and thus the vertical gutter T is constructed. Is done.

  Therefore, in the illustrated vertical rod T, when the connecting tool 20 is connected to the support tool 15 and fastened, as shown in FIG. 1, the operating point is in a state where the fulcrum portions 35c and 35c of the lever members 35 and 35 are abutted. The levers 35a and 35a are engaged with the engaging grooves 11 and 11, respectively, and the force point portions 35a and 35a sandwiching the support arm 30 therebetween are fastened by the fastening means 25, so that the lever principle works, that is, from the fulcrum portion 35c. When a fastening force by the fastening means 25 is applied to the force point part 35a far away, the action point parts 35b and 35b close to the fulcrum parts 35c and 35c rotate in a direction to push open the connecting ribs 10b and 10b with the fulcrum part as a fulcrum, The tightening force by the fastening means 25 acts as a large pressing force at the action point portions 35b and 35b. Therefore, the action point portions 35b and 35b strongly pressurize the outer peripheral surface between the connecting ribs 10b and 10b, And engaged with the engaging groove 11, 11 in a strong pressure state of, thereby firmly fastened by connecting a down pipe body 10 with connector 20 to the support 15.

  Moreover, in the illustrated vertical rod T, the connecting ribs 10b and 10b of the vertical rod main body 10 project obliquely from the outer peripheral surface in a direction facing each other, and the groove sections gradually taper toward the rear side. On the other hand, since the action point portions 35b and 35b of the lever members 35 and 35 are formed in a tapered shape in accordance with the groove shape of the engagement grooves 11 and 11, the fulcrum portions 35c and 35c are abutted against each other. In this state, when the action point portions 35a and 35a are engaged with the engaging grooves 11 and 11 and the force point portions 35a and 35a sandwiching the support arm 30 therebetween are tightened by the fastening means 25, the action point portions 35b and 35b are The engagement between the engaging grooves 11 and 11 is engaged with the engaging grooves 11 and 11, and the vertical rod main body 10 is firmly coupled to the support 15 and attached to the wall W. Thus, the lever principle works, and the attachment strength of the vertical rod main body 10 to the wall W is remarkably increased.

  In the illustrated vertical rod T, when the connecting tool 20 is connected to the support 15 and fastened, the action point portions 35b and 35b of the pair of lever members 35 and 35 are separately engaged with the engaging grooves 11 and 11, respectively. I let you. However, in the coupling tool 20 in the illustrated example, the fulcrum portions 35c and 35c of the lever members 35 and 35 are formed in a semicircular shape so as to be convex toward one side in the thickness direction of the force point portions 35a and 35a. Thus, the fulcrum portions 35c and 35c are originally made to function as fulcrums, but at the same time, as shown in FIG. 10, for example, a string member 39 such as a rubber band is wound around to couple the two insulator members 35 and 35 together. An auxiliary function can also be exhibited as a winding part. Therefore, when using the auxiliary function of the fulcrum portions 35c and 35c and engaging the action point portions 35b and 35b of the pair of lever members 35 and 35 with the engagement grooves 11 and 11, the fulcrum portions 35c and 35c After the member 39 is wound and the lever members 35 and 35 are connected, as shown in FIG. 11, the force point portions 35a and 35a are rotated in the opening direction with the fulcrum portions 35c and 35c as fulcrums, so 35b and 35b are brought close to each other, and once the distance between the action point portions 35b and 35b is made narrower than that between the connecting ribs 10b and 10b, as shown in FIG. The 35 action point portions 35b and 35b can be easily engaged with the engagement grooves 11 and 11.

  Accordingly, FIGS. 14A to 14D illustrate a construction method for attaching the vertical rod main body 10 to the wall W by using the auxiliary function of the fulcrum portions 35c and 35c. As shown in FIG. Step of engaging the reduced action point portions 35b and 35b with the engagement grooves 11 and 11 in order to engage the action point portions 35b and 35b of the members 35 and 35 with the engagement grooves 11 and 11 at a time. Accordingly, the number of work steps is less than that of the construction method that does not use the auxiliary function shown in FIG. 5, and the work efficiency can be increased and the attachment workability can be improved.

  By the way, in the above-described vertical gutter T, the support 15 of the vertical gutter body 10 has the support arm 30 screwed into the anchor 12 driven into the mounting hole of the concrete wall W so that the slat portion 30b protrudes from the wall W. It was the support means of the structure. However, in the downspout of the present invention, the support of the downspout main body 10 only needs to have a shape and structure that can be fastened by being sandwiched between separate insulator members. However, the present invention is not limited to this, and various types such as a support tool 45 having a structure as shown in FIG. 14 can be used as the support tool.

  The support tool 45 of the other example shown in the figure is composed of only a support arm formed in a T shape by bonding L-shaped angle plates back to back. The T support tool 45 is attached to a wall W with a mounting piece 45a and a connecting tool. This is a support means that is formed by an arm portion 45b that is sandwiched and fastened by 20 lever members 35 and 35 and is directly attached to the wall W. Therefore, the support tool, that is, the support tool 45 is provided with a screw insertion hole 46 for screwing in the attachment piece 45a, and the arm part 45b has two bolt insertion holes 49 made of long holes in series in the longitudinal direction. Are arranged side by side.

  Therefore, in the vertical rod T of the other example shown in the figure, when the vertical rod main body 10 is attached to the wall W, the wall W only needs to be capable of screwing the support tool 45 such as a plate wall. Accordingly, first, as shown in FIG. 15 (A), the mounting piece 45a is screwed at a predetermined position with an interval in the height direction of the wall W of the building to which the vertical gutter main body 10 is attached, and the arm portion 45b is fixed. The T-shaped support tool 45 is set on the wall W in a state of being protruded upright.

  Next, after the vertical rod main body 10 is arranged with the connecting ribs 10b and 10b facing the arm portion 45b, the point of action of the lever member 35 on one side of the arm portion 45b as shown in FIG. 35b is engaged with the engagement groove 11 on one side, and the force point portion 35a is overlaid on the arm portion 45b. Then, as shown in FIG. 15 (C), a pair of lever members 35 is formed on the other side of the arm portion 45b. Is engaged with the engagement groove 11 on the other side, and the arm portion 45b is sandwiched between the force point portions 35a and 35a with the convex side of the fulcrum portions 35c and 35c abutting, and the bolt insertion holes 14 and 49 are inserted. The connecting tool 20 is set in a sandwich state in which are connected. Thereafter, as shown in FIG. 15D, the connector 20 is fastened to the support tool 45 by the bolt 25a and the nut 25b of the fastening means 25. That is, after the bolt 25a is passed through the bolt insertion holes 14 and 49 of the arm portion 45b, the nut 25b is tightened into the threaded portion of the bolt 25a, and as shown in FIG. 35 is fastened to the support 45. As described above, when the connecting tool 20 is fastened to the T-type support 45 at each predetermined position in the height direction of the plate wall W, the vertical gutter body 10 is attached to the wall W of the building, and thus the vertical gutter T is Built.

  Now, in the illustrated vertical rod T described above, the lever members 35 and 35 of the connector 20 are formed in a convex shape toward one side in the thickness direction of the force point portion 35a by bending the fulcrum portions 35c and 35c in a semicircular shape. It was a thing. However, in the downspout of the present invention, the coupling tool is such that the fulcrum portions of the pair of lever members are in contact with each other, and the action point portions are engaged with the engaging grooves 11 and 11 of the downspout main body 10, and the support tool is interposed therebetween. As long as the force point part sandwiched by the fastening means 25 is tightened, the principle of the lever works, and the action point part at the tip may rotate in a direction to open and open the connecting ribs 10b and 10b with the fulcrum part as a fulcrum. Therefore, the fulcrum portions 35c and 35c are not limited to those that are bent in a semicircular shape and formed convex toward one side in the thickness direction of the force point portions 35a and 35a. For example, as shown in FIGS. The fulcrum parts 35c and 35c are formed in a convex shape having a hump-shaped cross section, and the action point parts 35b and 35b extending at the tips of the fulcrum parts 35c and 35c are formed in a tapered convex shape having a cross-sectional shoe shape. Can be used as a connector.

  Further, in the downspout of the present invention, the connecting tool is such that the fulcrum portions of the pair of lever members are in contact with each other, and the action point portions are engaged with the engaging grooves 11 and 11 of the downspout main body 10, and the support tool is interposed therebetween. For example, if the force point portion sandwiched by the fastening means 25 is tightened by the lever principle, the action point portion at the tip rotates in a direction to open and open the connecting ribs 10b and 10b using the fulcrum portion as a fulcrum. As shown in FIGS. 18 and 19, the tip portions 35 d of the lever members 35, 35 are formed in a cross-sectional boot shape, and the heel portions of the tip portions 35 d are formed as convex fulcrum portions 35 c, 35 c, For example, the side may be formed as a tapered convex action point portion 35b or 35b.
