Description

[Detailed description of the invention] (Industrial field of application) The present invention relates to a gutter receiving fitting that firmly supports and firmly fixes the gutter body, which is deformed due to various loads. .

(Prior art) There are various types of metal fittings that support the gutter body, but the one shown in Figures 8 and 9 is a so-called internal hanging type metal fitting A. The rising part c of the claw C provided at the front part of the receiving fitting main body B is engaged with the groove F formed downwardly inside the front ear part E of the main body D, while , the gutter body D is supported by engaging an engaging portion provided at the rear of the receiving metal body B.

However, this receiving metal fitting A has the above-mentioned claw C.
is formed by simply bending a rigid material such as a steel plate into an L-shape, and the upper end of the rising portion c is formed into a curved shape so that it can slide freely in the length direction within the groove F. Therefore, if a load is applied to the gutter body D in the expansion direction, including a downward load, due to snow accumulation, etc., it will not be able to follow this deformation, and as shown in Figure 9. The lever part falls off from the groove F. In addition, if the bracket A itself is incorrectly installed in a bent position, both ends of the rising part C of the claw C will obliquely block the groove F, and this part will act as a lever, causing the gutter as described above. This may cause obstruction to expansion or extension.

(Purpose) In view of these points, the present invention can closely follow the deformation of the gutter body in the width direction, and can securely fix the gutter body in the internal hanging method, while also preventing accidental bending. The purpose of the present invention is to provide a receiving metal fitting that can allow deformation of the gutter body in the width direction even if it is installed with a
The feature is that the rising part of the claw provided at the front of the receiving metal body is locked into the groove formed downward inside the front ear of the gutter body, while By removably engaging the engaging portion provided at the rear of the receiving metal body, the pawl is attached to the rear of the rising portion provided at the tip of the pawl in the receiving metal fitting that supports the gutter body. The main feature is that a spring portion that expands and contracts in the width direction of the main body is formed integrally with the rising portion.

(Example) The present invention will be described in detail below based on the illustrated example.

1 and 2 show a receiving fitting according to an embodiment of the present invention, and reference numeral 1 in the figures indicates a receiving fitting main body formed of a rigid material such as an iron plate to an appropriate width; The rear end of a second claw support plate 2 formed in a flat plate shape from the same material as the receiving metal body 1 is fixed to the front part, and this support plate 2 extends forward to support the gutter body. The length is set so that it can penetrate into the lower part of the downward groove, and its tip 2a enters into a rising part 4c of the first claw 4, which will be described later. Note that a normal fitting part 3 is formed at the rear part of the receiving metal body 1 and is detachably fitted to the rear ear part of the gutter body.

Reference numeral 4 denotes a first pawl that is paired with the support plate 2, and this pawl 4 connects a wire rod having a diameter smaller than the width of the downward groove of the gutter body into a U-shape with a width that is approximately the same as the width of the support plate 2. The bottom part 4a is further bent to stand up, thereby forming an L-shape as a whole, and a downwardly rounded spring part 4c is formed in the middle of both arm parts 4b. ing. The first claw 4 is integrated with the receiving metal body by welding the ends of its both side arm portions 4b, 4b to the lower surface of the support plate 2. It goes without saying that each bent portion of the first claw 4 is curved smoothly with an radius.

Also, in the figure, numeral 5 is the gutter body, 6 is its front ear,
Reference numeral 7 indicates a groove formed integrally downwardly inside the front ear portion 6 along the ear portion 6, and 8 indicates a rear ear portion of the gutter body.

Therefore, when using the claw 4, as in the conventional example,
The rising part 4a is inserted into the concave groove 7 from below and locked, and the fitting part 3 provided at the rear of the receiving metal fitting body 1 is
If you fasten it to the rear ear part 8 of the gutter body 5, the gutter body 5
is suspended and supported by a receiving metal fitting 1.

First, for example, when a load is applied to the gutter body 5 in the direction of expanding it, the rising portion 4a, which is locked in the groove 7, as shown in FIG. 6 outward (left arrow direction in the figure)
As a result, both spring portions 4c, 4c
As a result, the rising portion 4a corresponds to the displacement of the groove 7 and is prevented from falling off. When the load is removed, the front ear part 6 of the gutter body 5 returns to its proper position, but at that time, the receiving metal fitting 1 also has both spring parts 4c, 4c of the claw 4.
It returns to its original position by the action of

On the other hand, when a load is applied in the direction of compressing the gutter body 5 as shown in FIG. This corresponds to the displacement of .

Next, when a downward load is applied to the gutter body 5,
As shown in FIGS. 4A and 4B, being pressed by the upper inner end 7a of the downward groove 7, the first claw 4 bends downward using its fixed point as a branch, absorbing this load, and at the same time The tip 2a of the support plate 2, which is the second claw, contacts the lower end of the groove 7, and this load is transferred to the second and fourth claws.
As a result, the load is distributed and it can withstand this load reliably.

Furthermore, although not shown, when a torsional load is applied to the gutter body 5, the rising portion 4 retained in the groove 7
A load will be applied to both upright parts of the side arm part a in opposite directions in the medial and medial directions, but as a result, the spring part 4c of one of the side arm parts 4b will extend to cope with the load in the external direction, while the other Spring portion 4 of side arm portion 4b of
As a result of c contracting and responding to the above inward load,
Even in such a case, the claws 4 can be prevented from falling out of the grooves 7.

Therefore, according to the present embodiment, it is possible to provide a receiving metal fitting that can handle not only loads applied to the gutter body 5 in the width direction but also loads from various directions.

Note that in the groove 7, the claw 4 has a rising portion 4.
Since they are only in line contact, they can slide appropriately against deformation of the gutter body, and the function of the spring parts 4c, 4c can be utilized without difficulty.

In addition, the structure of the claw can be changed to various other structures as long as a spring part that can be expanded and contracted in the length direction of the claw is provided at the rear of the rising part. As shown in Fig. 5, the support plate is not provided with a second claw support plate, and is made only of wire material, or as shown in Fig. 6, it is made of a plate material. It is also possible to use one formed by the above method. In both embodiments, reference numeral 14 in the figure
a and 24a are rising portions, and 14c and 24c are spring portions. In both of these embodiments, the claws 14, 2
4 has its rear end fixed to the front part of the receiving metal body (not shown).

The operation of these embodiments is basically the same as that of the first embodiment described above.
If the claw 14 shown in Fig. 5 is used, it is possible to prevent the receiving fitting from falling off due to the load and twisting force applied in the width direction of the gutter body, while if the claw 24 shown in Fig. 6 is used, the load and twisting force applied in the width direction of the gutter body can be used. It is possible to prevent the receiving fitting from falling off due to the load, and in both embodiments, the present invention can be most simplified and can contribute to a reduction in manufacturing costs.

Furthermore, in the embodiment shown in FIG. 7, when fixing the claw 24 of the embodiment shown in FIG.
1, the pawl 24 is configured to be able to rotate horizontally with respect to the receiving fitting main body 11, so that the receiving fitting main body 11 and the gutter main body are not positioned vertically. In this case, the rising portion 24a of the pawl 24 can be engaged with the groove of the gutter body. According to this embodiment, the claw 24 can be reliably locked in the groove even if the receiving metal fitting is bent and attached. Although not shown, the rear end of the claw similarly formed from wire may be semi-caulked to the front part of the receiving fitting body via a rivet, so that it can be fixed rotatably in the horizontal direction. .

However, within the scope of this invention, without departing from its spirit,
It goes without saying that various design changes are possible.

(Effects) As described above, according to the present invention, a spring portion that can be expanded and contracted in the width direction of the gutter body is integrally formed on the claw that is locked in the downward groove inside the front ear of the gutter body. Therefore, even if a load is applied to the gutter body in the width direction and the ear portion expands or contracts, the spring portion can expand and contract to follow the displacement, and the claw at the front of the receiving metal body will fit into the groove. It will not come off, and the gutter body can be reliably suspended and supported.

In addition, according to the present invention, even if the gutter is installed crookedly on the wall, the claws themselves can expand and contract in the width direction of the gutter body, so when a load is applied,
The gutter body can be expanded or contracted in the width direction.
