Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an eaves gutter support tool used to support eaves gutter provided at the eaves of a building.

(Prior Art) Some eaves gutter supports are of a hanging type that supports eaves gutter in a suspended state by locking gutter ears formed on one eave gutter.

In such eaves gutter supports, when the gutter ears are locked in the locking parts, the 811 ears are easily inserted into the locking parts, and the gutter ears are not detached from the locking parts. It is required to satisfy various conditions such as external forces applied to the eaves gutter, thermal expansion/contraction and deformation of the eaves gutter itself, mobility to absorb unevenness of the fascia board, and structural simplicity.

Conventional eaves gutter supports that take into account the above-mentioned conditions include, for example, Japanese Utility Model Application No. 60-42831 and Japanese Utility Model Application No. 5
The one described in Japanese Patent No. 9-69337 is known.

In the former eaves gutter support, locking portions to which the gutter ears of the eaves gutter are locked are formed at both ends of the support rod, and a spring plate is mounted inside the locking portions. That is, when inserting the gutter lug into the locking portion, the spring plate is pushed in while being elastically deformed, and the spring plate restores its original shape after insertion, thereby preventing the gutter lug from coming off.

In addition, the latter eaves gutter support has a supporting rod connected at the center with a hinge, locking parts formed at both ends, and a retaining plate elastically supported on the underside of the supporting rod via a spring. there were.

Therefore, when inserting the gutter ear into the locking part, lift the retaining plate upward against the support rod and push it in. After insertion, the pull-out plate returns to its original state and prevents the gutter ear from coming off. there were. In addition to the fact that the retaining plate is elastically supported,
The ability of the support rod to make circular movements around the hinges prevents external forces applied to the eaves gutter, thermal expansion, contraction and deformation of the eaves gutter itself,
It was able to absorb some of the unevenness of the fascia board.

(Problem to be Solved by the Invention) However, the former eaves gutter support device is difficult to use when an external force is applied to the eaves gutter, when the eaves gutter itself expands, contracts or deforms due to heat, or when the fascia board becomes uneven. In some cases, one eaves gutter moves somewhat relative to the eaves gutter support due to the elastic deformation of the spring plate, and although attempts are made to absorb these external forces, thermal expansion, contraction and deformation of the eaves gutter, and unevenness of the fascia plate, the spring The board is basically
Since the gutter ears are supported under pressure so as not to fall from the locking portion, it has been difficult to satisfy both the ability to prevent the gutter ears from being pulled out and the mobility of the eaves gutter.

In addition, the latter eaves gutter support requires many parts such as a support rod divided into parts, a hinge, a spring, and a retaining plate, and requires time and effort to assemble them. Therefore, there are problems in that the number of parts increases, and the manufacturing efficiency becomes poor (and the structure becomes complicated) due to the labor required for assembling these parts.

Furthermore, by allowing the support rod to make a circular motion using the hinge as a fulcrum, it can absorb the external force applied to the eaves gutter, the thermal expansion, contraction and deformation of the eaves gutter itself, and the unevenness of the fascia board. The spacing between the locking parts of the gutter became unstable, and the ability to prevent the gutter ears from being pulled out was also lacking.

The present invention aims to solve the above-mentioned conventional problems and provide an eaves gutter support that satisfies all of the requirements of insertability, removal prevention, mobility, and structural simplicity.

(Means for Solving the Problems) In order to achieve the above object, the eaves gutter support of the present invention includes:
An eaves gutter support device is formed with a locking portion to which a gutter ear of an eaves gutter is locked, the locking portion having a locking protrusion that engages with the gutter ear, and the locking protrusion having a locking portion that engages with the gutter ear. Opposing retaining protrusions are formed, and cutouts are formed in the retaining protrusions and the retaining protrusions so that they can be bent and deformed.

(Function) In the eaves gutter support of the present invention, by inserting the gutter lug of the eaves gutter from between the locking protrusion and the retaining protrusion formed in the locking part, the locking protrusion can be attached to the gutter lug. to support the eaves gutter in a suspended state.

In this case, since the locking protrusion and the retaining protrusion can be bent and deformed by the notch, the gap between the locking protrusion and the retaining protrusion is widened by these bending deformations, making it easy to insert the gutter lug. can be done.

Further, since the retaining protrusion is provided opposite to the retaining protrusion, this is effective in preventing the retaining protrusion from coming off from the gutter ear.

In addition, by bending and deforming the locking protrusion and the retaining protrusion, one eaves gutter can slide in the front and back direction relative to the eaves gutter support, so the sliding of this eaves gutter causes external force to be applied to the eaves gutter. Ya1
It can absorb the thermal expansion and contraction of the eaves gutters themselves and the unevenness of the fascia board.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, the configuration of the embodiment will be explained with reference to FIGS. 1 to 5.

FIG. 1 shows an eaves gutter support structure in which one eave gutter l is attached to a building fascia board 3 using the eaves gutter support 2 of this embodiment. In addition, 4 is a rafter.

A front wing 15 is formed at the upper end of the front side wall 13 to protrude outward, and a recess 16 that opens to the inner surface of the gutter is formed inside the front wing 15. A hanging piece 17 is provided vertically so as to close the upper half of the opening.

The eaves gutter support 2 is an integrally molded synthetic resin product.

Synthetic resins with excellent weather resistance, such as polycarbonate resins, are used.

The main body of the eaves gutter support 2 is composed of a fixing part 21 fixed along the fascia plate 3 and a support rod part 22 extending forward from the upper end of the fixing part 21. ing.

The support rod portion 22 includes a horizontal base portion 221 extending forward from the upper end of the fixing portion 21, a downward portion 222 extending downward from the horizontal base portion 221, and a downward portion 222 extending forward from the downward portion 222. It consists of a horizontal portion 223 that extends upwardly from the horizontal portion 223, and an upwardly inclined portion 224 that extends forward and upward from the horizontal portion 223.

Further, the eave gutter support 2 includes a rear piece locking portion 23 to which the rear page 14 is locked, and a front page locking portion 24 to which the front wing 15 is locked.
is formed.

As shown in FIG. 2, the rear piece locking part 23 includes a locking protrusion 23a that projects from the fixing part 21 so as to engage with the lower surface 18 of the rear page 14, and a locking protrusion 23a into which the rear page 14 is inserted. A retaining protrusion 23b is provided to protrude from the downward portion 222 so as to hold the gap 23c and face the retaining protrusion 23a.

The locking protrusion 23a and the retaining protrusion 23b9 have cutouts 5a and 5b formed on their lower surfaces, respectively, and are formed to be bendable and deformable using the cutouts 5a and 5b as fulcrums. Further, the cutout portion 5a.

5b, each of the openings 51a and 51b is formed narrower than the inner part, and this opening 51a.

At the position where 51b is closed, the locking protrusion 23a and the retaining protrusion 23
Bending deformation of b is regulated.

As shown in FIG. 3, the previous page locking portion 24
A locking protrusion 24a formed at the upper end of 24 and engaged with the recess 16 of the front wing 15, and a groove 24 into which the hanging piece 17 is inserted.
and a retaining protrusion 24b that faces the locking protrusion 24a and holds the retaining protrusion 24b in between. The retaining projection 24b has upper and lower lip portions 24d and 24e, and each of the lip portions 24d and 24e is formed to have a narrow width so that it can be bent and deformed. Further, the retaining protrusion 2
The upper surface of 4b is formed into an inclined surface that descends toward the groove portion 24c.

Further, the base portion of the previous page locking portion 24 and the upwardly inclined portion 2
A notch 5 is formed on the lower side of the page 24, and the entire front page locking portion 24 can be bent and deformed using the notch 5 as a fulcrum. Also.

The opening 51 of the notch 5 is formed narrower than the inner part, and bending deformation of the front page locking part 24 is restricted at the position where the opening 51 is closed.

Next, the operation of the embodiment will be explained.

When supporting the eaves gutter l with the eaves gutter support 2 of this embodiment, the eaves gutter support 2 is fixed to the fascia slope 3 at the fixing part 21, and first, the eaves gutter l is fixed to the fascia slope 3 using the rear piece locking part 23. The rear page 14 of the gutter l is locked, and the front wing 15 of the eaves gutter l is locked at the front page locking part 24.

The rear page 14 is locked by the rear piece locking portion 23 by pushing the rear page 14 through the gap 23c between the locking protrusion 23a and the retaining protrusion 23b, and engaging the locking protrusion 23a with the lower surface 18 of the rear page 14. It is done by doing. The retaining protrusion 23b comes close to (or may come into contact with) the inner surface of the rear wall 12.

In this case, since the locking protrusion 23a and the retaining protrusion 23b can be bent and deformed using the notches 5a and 5b as fulcrums, respectively, the gap 23c between the retaining protrusion 23a and the retaining protrusion 23b is the same as the notch 5a, It spreads due to bending deformation of 5b, later page 14
can be easily inserted.

Further, since the retaining protrusion 23b is provided opposite to the retaining protrusion 23a, the retaining protrusion 23a is attached to the lower surface 18 of the rear page 14.
It is effective in preventing it from coming off.

Furthermore, by bending and deforming the locking protrusion 23a or the retaining protrusion 23b, one eaves gutter l can slide in the front and back direction with respect to the eaves gutter support 2, so that the eaves gutter l is protected from snow or lightning loads. If an external force is applied to the eaves gutter due to a ladder or collision with a ball, if the eave gutter itself experiences thermal expansion, contraction or deformation due to temperature changes, or if the fascia plate 3 has unevenness, the eave gutter l slides back and forth. If an external force is applied to the eaves gutter l due to this sliding of the eaves gutter l, this external force can be absorbed and damage to the rear page 14 can be prevented.
When thermal expansion, contraction or deformation occurs in the eaves gutter l itself, it is possible to absorb the movement of one eave gutter l in the axial direction or the front-rear direction, thereby preventing deformation of the eaves gutter l or disconnection of the connection part, If the fascia plate 3 has unevenness, the unevenness is absorbed and the rear page locking part 2
One eaves gutter 1 can be properly attached to the eaves gutter support 2 by absorbing the error in the relative position between the eaves gutter 3 and the rear page 14. Figure 4 shows the rear page locking part 23 when one eaves gutter l slides backward.
FIG. 5 shows the rear page locking portion 23 when the eaves gutter l moves forward.

The front page 15 is locked by the front page locking portion 24 by engaging the locking protrusion 24a with the recess 16 and inserting the hanging piece 17 into the groove 24c. In this case, since the lips 24d and 24e of the retaining protrusion 24b can be bent and deformed, the retaining protrusion 24a can be inserted into the recess 16 and the groove 24c can be bent.
The hanging piece 17 can be easily inserted into the holder.

In addition to the bending deformation of the lips 24d and 240 of the retaining protrusion 24b, the engagement protrusion 24a can be bent and deformed as a whole using the notch 5 as a fulcrum. It becomes possible to slide in the direction. That is, external forces applied to the eaves gutter 1, thermal expansion, contraction and deformation of the eaves gutter 1 itself, and unevenness of the fascia board 3 can be absorbed. Furthermore, the retaining protrusion 24
b, so that the locking protrusion 24a is on the lower surface 19 of the rear page 18.
It is possible to reliably prevent it from coming off.

As described above, the eaves gutter support 2 of this embodiment has the rear page 14 and front page 15 for the rear page locking part 23 and the front page locking part 24.
In addition, the rear page 14 and the front page 15 do not come off from the rear page retaining part 23 and the front page retaining part 24, and furthermore, it is possible to prevent external forces from being applied to the eaves 1t and the eaves gutter l itself. It is also possible to absorb thermal expansion, contraction, deformation, and unevenness of the fascia plate 3. Moreover, by making it an integrally molded synthetic resin product, even a somewhat rough shape can be efficiently formed in one molding process. Note that only the rear piece locking portion 23 and the front page locking portion 24 may be formed of synthetic resin, and the other portions may be formed of metal.

Although one embodiment of the present invention has been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and even if there is a design change or the like within the scope of the present invention, it is included in the present invention. It will be done.

For example, the front page locking portion may have the same structure as the rear page locking portion.

(Effects of the Invention) As explained above, the eaves gutter support of the present invention has a simple structure in which notches are formed in the locking protrusion and the retaining protrusion, but the gutter ear It can be easily inserted into the locking part, prevents the gutter ears from coming off the locking part, and is extremely effective against external forces applied to the eaves gutter, thermal expansion and contraction of the eaves gutter itself, and unevenness of the fascia board. The effect is that it can be absorbed into the body.
