Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for manufacturing a copper gutter holder, and more particularly to an improvement in a method for manufacturing a support rod that supports a saucer.

[Prior Art] Generally, when a rain gutter is fixed to the eaves, as shown in Fig. 1, a U-shaped saucer l is used to receive the rain gutter, and the tip is fixed to the saucer 1 and the base end is on the side of the house. It is customary to use a gutter holder having a support rod 2 driven into the gutter.

By the way, in the past, a bar material was usually used as the support rod 2 of this type of gutter holder, and the method of fixing the saucer l to the tip of this support rod 2 was as shown in FIGS. 2 and 3. The method adopted is to form a slender insertion part 2a at the tip of the support rod 2 by cutting, insert this insertion part 2a into the hole 1a provided in the saucer l, and tighten the tip as shown by the chain line in FIG. It is being

[Problems to be solved by the invention] However, as houses have become more upscale in recent years, there has been a trend to make not only rain gutters but also gutter holders made of steel, and in this case, expensive steel bars are used as the support rods 2. The disadvantage of using this method is that the cost of the gutter holder is extremely high.

In addition, in the case of a rod-shaped support rod 2, the area of the catch 3 for the catch plate l formed at the base end of the insertion portion 2a becomes very small, as shown in FIG. Even if this is done, there is a drawback that the saucer l may wobble due to shock during transportation.

In addition, the insertion portion 2a has to be processed in the next step after the bar material is cut to size, which increases the number of man-hours, which further increases the cost.

The present invention was developed in view of the current situation, and it is possible to significantly reduce costs by reducing material quality and processing man-hours, and to strengthen the connection between the support rod and the saucer, thereby greatly increasing the strength against external forces. It is an object of the present invention to provide a method for manufacturing a gutter holder that can improve the performance of the gutter holder.

[Means for Solving the Problems] The present invention provides a support rod as a means for achieving the above object.
A relatively inexpensive steel flat plate is bent into a groove shape and bent into a dogleg shape on the tip end to form a support rod. A rising piece is integrally provided with the upper part left as 1, and this rising piece is inserted into a hole provided in a copper saucer, and its tip is tightened to fix the saucer. It is characterized in that the width of the plate is narrowed in advance and a hole is provided in the center in the width direction of the plate.

[Function] In the method for manufacturing a gutter holder according to the present invention, the support rod is formed by bending a relatively inexpensive copper flat plate into a groove shape and bending the tip side into a dogleg shape. Ru. Therefore, material costs and processing man-hours are reduced, making it possible to significantly reduce costs.

In addition, the plate width of the dogleg-shaped bent portion of the support rod is narrow in advance, and a hole is provided in the center of the plate in the width direction, so this part becomes more fragile than other parts.
When bending a support rod into a dogleg shape, the portion to be bent can be accurately and easily bent. Also, when bending a support rod into a dogleg shape, if the bent part has the same width as the other parts, the grooves on both sides of the bent part will bulge and require secondary processing, but the width should be narrowed in advance. There is no need for this, and the hole can be used as a drainage hole to drain rainwater that has accumulated inside the support rod.

Further, a rising piece is integrally provided at the tip of the support rod, leaving at least both end portions in the extending direction of the tray as a catch. After this rising piece is inserted into a hole provided in a copper saucer, its tip is tightened, thereby fixing the saucer. Therefore, a wide receiving seat is secured, and the connection between the support rod and the receiving tray is strengthened, thereby making it possible to significantly improve the strength against external forces.

[Embodiment] The present invention will be described below based on a first embodiment shown in FIGS. 4 to 7.

Figures 4 and 5 show a copper gutter holder for fixing an arc-shaped gutter to the eaves.
This is a support rod that supports 1 on a rafter or the like. The saucer 11 is
It has an arc shape that follows the external shape of the gutter, and the center part in the board width direction has a reinforced structure with a groove-shaped bead 13 that protrudes outward except for the tip of the arc. ing.

As shown in FIG. 4, holes 14 are formed at the tips of the circular arcs of the saucers 11, and these holes 14 are bent inward as shown by chain lines in FIG. 4 to support the gutter. A claw metal fitting 15 is attached. As shown in FIGS. 4 and 5, the claw metal fitting 15 is formed of a thin copper plate, and a protruding portion 15a having a closed tip is formed by drawing or the like in a portion facing the hole 14. It is being The claw metal fitting 15 is fixed to the saucer 11 by inserting the protrusion 15a into the hole 14 and tightening its tip.

As shown in FIGS. 4 and 5, the distal end portion of the support rod 12 is connected and fixed to the arcuate bottom position of the saucer 11 constructed in this manner, and the base end portion of the support rod 12 is It is designed to be driven into the end surface of a rafter (not shown).

The support rod 12 is made by punching a copper flat plate into the shape shown in FIG. 6 to form a base material 16, and bending this base material 16 into a groove shape as shown in FIGS. 4 and 5. At the same time, the tip side is raised in a dogleg shape with an internal angle of approximately 70 degrees.
By adjusting the rising dimension L (fourth figure), the gutter can be sloped. The two (2) rising pieces 17 integrally provided on the rising end surface of the support rod 12 are connected to the two holes 18 provided in the arcuate bottom of the saucer 11 as shown in FIGS. 4 and 5. , and the protruding tips are tightened as shown by the chain lines.

Thus, the saucer 11 and the support rod 12 are firmly and rigidly connected.

The base material 16 has a generally band-shaped outer shape as shown in FIG. 6, and two rising pieces 17 are provided on its tip surface, that is, the left end surface in FIG. The portion 19 of the surface other than the rising piece 17 is bent into a V-groove shape to form the support rod 12, as shown in FIG. ing.

In addition, as shown in FIG. 6, notches 21 are formed from both sides in the plate width direction at the tip side portion of the base material 16 corresponding to the dogleg-shaped bent portion of the support rod 12 bent at an internal angle of about 70 degrees. A hole 22 is provided in the center of the plate in the width direction.

These notches 21 and holes 22 allow for accurate and easy processing when bending into a dogleg shape, and both notches 21 allow for easy processing when bending into a dogleg shape. This prevents the V-groove flesh end HA (see Fig. 4) of the bent portion from rising and requiring secondary processing.

Further, the hole 22 can be used as a drain hole for draining rainwater accumulated in the groove when the support rod 12 is formed by bending as shown in FIG.

In addition, the base end of the base material 16, that is, the right end in FIG. 6, is provided with a support rod 12 that can be pulled out when driven into the tip surface of a rafter, etc., as shown in FIGS. 4 and 5. A block 23 for preventing I is integrally provided.

Next, a method of manufacturing the gutter holder according to this embodiment will be described.

When manufacturing, first, a copper flat plate is punched out and the sixth
A base material 16 having the shape shown in the figure is formed. And this base material 1
6 is placed in a mold and subjected to compression processing.

Then, the groove-shaped bending process and the dogleg-shaped bending process are performed in a series of operations, and the support rod 12 shown in FIGS. 4 and 5 is formed.

Next, the rising piece 17 at the tip of the support rod 12 is inserted into the hole 18 of the saucer 11 that has been formed in advance, and the tip is tightened. Tighten and fix.

Therefore, it is possible to form the support rod 12 by bending an inexpensive flat plate material instead of using an expensive 4"A bar material, and since it requires less material to obtain the same strength as a bar material, it is possible to significantly reduce the cost. Cost reduction becomes possible.

In addition, when using a bar, insert: m as shown in Figure 2.
The processing of 28 or the processing of the pull-out stopper at the base end of the support rod 2 must be a separate process from the cutting of the bar to the specified size.
In the case of using a plate material, all the parts are formed at the same time by punching the base material 16 shown in FIG. 6, so that the number of man-hours is significantly reduced. Therefore, together with the reduction in material costs, the total cost can be significantly reduced.

In addition, in the case of the groove-shaped support rod 12, the apparent upper area of the catch 20 can be made much larger than that of the catch 3 in the case of the rod shown in FIG. 11 can be supported. In addition, the tightening part has two rising pieces 17.
Therefore, there are two locations, and since the two rising pieces 17 have a V-shape as shown in FIG. 5, a strong tightening force can be obtained. Therefore, due to the large area of the seat 20 and the strong tightening force provided by the two rising pieces 17, the resistance against external forces can be greatly improved.

Further, since the support rod 12 is groove-shaped, it is possible to effectively prevent rattling around the axis when driving into the tip end surface of a rafter, and stable support of the mallet is achieved.

Further, the claw metal fitting 15 has its protruding portion 15a connected to the hole 1 of the saucer 11.
4 and tighten the tip to create saucer 1.
1, it is cheaper than using base parts such as rivets. In addition, when making holes in the claw metal fittings 15 and turning them into rivets, since the claw metal fittings 15 are made of a thin plate material, there is a risk that the holes in the claw metal fittings 15 will expand in diameter and become loose when tightening the rivet. When using part 15a,
There is no such fear at all. Further, since the protrusion 15a has a cylindrical shape with a closed end, a stronger tightening force can be obtained than in the case of a cylindrical shape with an open end.

Note that such a narrowing direction is not limited to the claw metal fitting 15, but can also be applied to a registration mark, for example, as shown in FIG.

That is, FIG. 8 shows a saucer 11' that is integrally provided with a support piece 24 that is screwed to the end surface of a rafter, etc., and a hole 24a is provided in the center of the support piece 24.
The dragonfly 25 is fixed to the support piece 24 by inserting a cylindrical protrusion 25a with a closed tip formed at the center of the dragonfly 25 by drawing or the like into the hole 24a and further tightening the tip. It looks like this. Also in this case,
Like the claw metal fitting 15, cost reduction is aimed at.

In addition to this, a strong connection can be obtained.

9 and 10 show a second embodiment of the present invention, in which a bulge 26 is provided at the bottom of the groove at the tip of the support rod 12 to increase the area of the seat 20, and This is a rising piece 27.

When configuring in this way, as shown in FIG. As shown in the figure, bending is performed using a concave lower mold 28 having a concave portion 28a at the bottom of the groove, and a convex V-shaped upper mold 29 having a convex portion 29a at the protruding tip. . Then, both types 28
, 29, the entire body including the vertically extending piece 27 is bent into a V-groove shape, and the bulging portion 26 is bulged by the V-shaped recess 2821 and the bulging portion 29a.

However, by configuring it like this, the area of the catch seat 20 can be made wider, and the rising piece 2
7 can be made larger to obtain stronger tightening force.

FIG. 13 shows a third embodiment of the present invention, in which the support rod 1
The tip end of the catch seat 20 is bent inside the groove, and the catch seat 20 is formed as a wide surface on the upper surface thereof, and two rising pieces 17 are raised from the center of the catch seat 20 in a single straight shape. It is something.

To construct this structure, a base material 16 having the same shape as the base material 16 of the first embodiment shown in FIG. 6 may be used, and this may be placed in a mold and bent. The catch seat 20 is bent arbitrarily by adjusting the clearance between the upper mold and the lower mold, and the rising piece 17 is also raised into a single piece at the same time as the catch seat 20 is processed by adjusting the shape of the mold. Therefore, the number of man-hours is not increased compared to the first and second embodiments, and in both cases, the support rod 12 is formed in one operation.

However, with this configuration, the catch 20 is formed as a wide surface, so the stability of the catch 11 is improved compared to when the end face itself is used as the catch. In addition, after the rising piece 17 is tightened, the catch 20 is bent.
Since springback can be expected, the strong connection between the saucer 11 and the support rod 12 can be maintained permanently.

In addition, since the rising piece 17 stands up as one piece, the hole on the side of the saucer 11 becomes one and becomes large, and the cutting die can be made larger accordingly, so the life of the cutting die is increased. can be extended.

FIGS. 14 and 15 show a fourth embodiment of the present invention, in which the base end portion of the support rod 12 is formed into a two-plate shape.

That is, as shown in FIGS. 14 and 15, a two-ply plate-shaped part 30 is bent at the proximal end of the groove-shaped support rod 12, and this plate-shaped part 30 and other parts are bent. As shown in FIG. 4, a boundary portion 31 is formed between the V-groove portion and the V-groove portion. In addition, the plate-shaped portion 30 includes FIGS. 14 and 15.
As shown in the figure, a long hole 32 having a long axis in the horizontal direction is provided.

However, by configuring it as a lever, it can be used as a support rod 12 of the type that is driven into the end surface of the rafter, or as a support rod 12 of the type that is screwed to the side surface of the rafter. In either case, the surface boundary portion 31 can be used as a reference for the mounting position, and construction is easy. Further, the elongated hole 32 functions as a pull-out stop when the support rod 12 is used as a driving type, and can be used as a hole for adjusting the screw position when used as a screw type.

16 and 17 show a fifth embodiment of the present invention, in which the base end portion of the support rod 12 is bent into a cylindrical shape, and the support rod 12 is driven into the tip surface of the rafter, etc. Also, the support rod 12 can be rotated around the axis.

That is, it is originally preferable that the support rod 12 does not move after being driven into the end surface of the rafter. However, depending on the structure of the house, if the support rod 12 is driven in in its normal state, the saucer may come into contact with the tip of the roof, making it impossible to drive the support rod 12 in place. Therefore, in such a case, place the gutter bracket horizontally and drive it halfway, then place the gutter bracket on the support rod 12.
It is necessary to rotate it around the axis to bring it into the normal state, and then drive it further to the normal position.

In this case, if the driven portion of the base end of the support rod 12 has a groove shape or a flat plate shape as in each of the embodiments described above, the above operation becomes impossible.

Therefore, in this embodiment, the base end portion of the support rod 12 having a V-groove shape as shown in FIG. 16 is changed to a cylindrical shape as shown in FIG. It is formed into a shape.

This makes it possible to rotate the support rod 12 around its axis.
It can be applied to houses of any structure. Further, the boundary portion 33 (completely black in FIG. 16) between the cylindrical portion and the V-groove portion can be used as a guide for the amount of implantation.

In each of the above embodiments, the support rod 12 has a V-groove shape, but the groove shape is limited to a V-groove shape, and may be a U-groove shape or a square groove shape. It has a shaped lip. A so-called lip groove shape may also be used.

[Effects of the Invention] As explained above, in the present invention, the support rod is formed by bending a flat plate made of I into a groove shape and bending the tip: JjAOlII into a dogleg shape. Significant cost reductions can be achieved by reducing material costs and processing man-hours.

In addition, the plate width of the dogleg-shaped bent part of the support rod is narrow in advance, and a hole is provided in the center of the plate in the width direction, so this part becomes weaker than other parts, making it difficult to support the rod. When bending a rod into a dogleg shape, the portion to be bent can be bent easily and accurately. Also,
When bending a support rod into a dogleg shape, if the width of the bent part is the same as the other parts, the grooves on both sides of the bent part will swell up and require secondary processing. This is not necessary. The holes can also be used as drainage holes to drain rainwater accumulated in the grooves of the support rod.

In addition, a rising piece is integrally provided at the tip of the support rod, leaving at least both end portions in the extending direction of the saucer as a catch, and this rising piece is inserted into a hole provided in a copper saucer, and the tip is machined. Since the saucer is fixed by tightening, a large saucer can be secured, and the connection between the support rod and the saucer can be strengthened to greatly improve the strength against external forces.
