Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement in the structure of a connecting part in an eave gutter, a curved gutter, etc.

(Prior art) Conventionally, in order to connect metal eaves gutters, one end of the lug portion formed on both longitudinal edges of the eaves gutters was raised using a tool such as a grip. After opening the selvage part of the other eaves gutter adjacent to the opening and fitting the selvage part of the other eave gutter adjacent to the opening, use the tool again to return the raised selvage part to its original position and open the other eave gutter. The ear wrap portions of the ear wraps are locked and connected, and the connecting portions are then bonded by soldering or the like to prevent rainwater from leaking from the connecting portions. Therefore, since the connection work at the construction site takes time and effort, there is a problem that the work is troublesome and takes a lot of time.

Therefore, in order to solve the above-mentioned problem, as shown in FIG. 2, and insert the connecting rod 4 into the selvage part 2' of the other adjacent eaves gutter 1' to connect the overlapping part 3 of the eaves gutter 1 to the other eaves gutter 1'.
A method has been proposed for connecting the eaves gutters 1 and 1' by crushing a part of the ear wrapping part 2' and locking it to the connecting rod 4 after polymerizing with the overlapping part 3'. (Refer to Utility Model Publication No. 57-7704, etc.).

However, in devices using this connecting rod, the end of the insertion hole of the ear wrap part into which the connecting rod is inserted is easily deformed, so when inserting the connecting rod, a tool such as a perforator must be used to insert the connecting rod into the insertion hole. In addition, since the ends of the eaves and gutters must be inserted so that they are facing each other, the ends touch each other, making it difficult to insert the connecting rod. There is. Furthermore, this structure requires a special member called a connecting rod, which requires parts management, and the structure is complex and requires many manufacturing steps, resulting in high costs.

In order to solve the above-mentioned problem, the applicant of the present application has provided an eave gutter 10, which is formed on both sides of the eaves gutter 10 in the longitudinal direction, at one end of the ear wraps 11, 11, as shown in FIG. Metal eaves gutter connection structure provided with a locking notch 12 that fits and locks the other ends of the ear wraps 11', 11' of the gutter 10' (Utility Application No. 59-165403 (Sho 61 -80917) (see specification).

(Problems to be Solved by the Invention) However, according to the above-mentioned connection structure, the structure is extremely simple, no other members are required, and connection can be easily made with one touch. We were able to solve the problem, but when connecting the eaves and gutters,
It is only for fitting and locking the selvedge parts 11', 11' of the other eave gutter a' into the latching notches 12, 12 formed in the selvage parts 11, 11 of one eave gutter a. As a result, the connecting surfaces that face each other at the connecting part may not be in perfect contact with each other, which may cause looseness at the connecting part, and there may be a level difference on the inner surface of the eaves gutter where rainwater flows down due to the overlap between the eaves gutter. There were problems such as not being able to solve problems that could be solved.

(Purpose of the present invention) Therefore, the present invention has an extremely simple structure, does not require extra members such as connecting rods, and
The work of connecting eaves gutters and gutter bends is made easier, and the connection parts can be reliably connected without soldering, etc., and by eliminating the difference in level due to overlap between the joints of eaves and gutters. An eaves gutter that can prevent the adhesive from deteriorating when it comes into contact with rainwater, eliminate rain leakage and peeling from joints, and also prevent the installation direction of the eaves gutter from being affected by the direction in which rainwater flows. It is intended to provide a connection structure for a curved gutter, etc.

(Means for Achieving the Object) To achieve this goal, in the present invention, in an eaves gutter that has an ear wrap formed on both sides of the longitudinal direction from the outside to the inside, the joint end side of one eave gutter is An engagement notch is provided in the longitudinal direction of the winding tip side by a predetermined length in a substantially symmetrical manner to fit and lock the end of the selvage part of the other adjacent eave gutter, and the notch has an upper outer side. A guide piece is integrally formed and extends in a curved direction.
When the ear wrap part of the other eaves gutter is press-fitted into the notch in the direction in which both eaves gutters overlap from above and below, the ear wrap part is configured to elastically engage with the notch, and the ear wrap part is adjacent to each other. At the joint where the eaves gutters overlap, a step for overlapping is formed that bulges outward, and a double-sided adhesive tape is interposed between the joining surface of the step and the other eaves gutter to connect the eaves gutters together. In this state, the inner surfaces of adjacent eaves gutters are continuous and substantially flush with each other, thereby achieving the intended purpose.

(Function) With the above-mentioned configuration, a double-sided adhesive tape is pasted in advance to the inner joint surface of the overlapping step part of one eave gutter, and the inner joint surface becomes the connection part of the other adjacent eave gutter. When overlapped with the outer joint surface and fitting and locking the selvage part on the connection side into the engagement notch provided at the end of the selvage part of one of the eaves gutters, the overlapping part of both eaves gutters is covered with double-sided adhesive tape. This allows the eaves and gutters to be firmly fixed by adhering them more closely. After connection, the inner surfaces of adjacent eaves gutters are continuous and substantially flush with each other without any difference in level due to overlap, and the double-sided adhesive tape is sandwiched and protected within the polymerization step. As a result, the adhesive tape will not be damaged by rainwater running down the eaves gutters.

(Example) The configuration of the present invention will be explained below with reference to an example shown in the drawings. A is an eaves gutter formed of, for example, a metal plate, and on both longitudinal edges of the eaves gutter a are formed ear wrap portions 21, 21 that are rolled inward,
Engagement notches 22, 22 having lengths corresponding to the portions overlapping with the other adjacent eaves gutter a' are provided on the inner sides of one ends of the ear wraps 21, 21 in a substantially bilaterally symmetrical manner. Guide pieces 23, 23 are integrally formed on the inner edges of the engagement notches 22, 22 and extend upwardly and outwardly in a curved manner. The width between the rising starting ends of both guide pieces 23, 23 is narrower than the width between the outer edges of the selvage parts 21, 21, and the engagement notches 22, 22 are provided with the selvage of the other eave gutter a'. If the winding parts 21', 21' are fitted, the ear winding parts 21', 2
1' reliably springs into engagement with the engagement notches 22, 22, and after engagement does not come off unless the eaves gutter a is expanded.

If the guide pieces 23, 23 are formed so that their upper edges are curved outward in an arc shape when viewed from the front, the guiding effect will be even better.

By the way, a polymerization step 24 that bulges outward is formed at the connection portion of the eaves gutter a where the other adjacent eave gutter overlaps, and a double-sided adhesive tape is placed on the polymerization step 24. One side of 25 is pasted. The other adjacent eaves gutter a' is polymerized and bonded to the polymerization step 24 via double-sided adhesive tape 25 to connect the eaves gutter a, a'.
When connecting eaves gutter a', the depth of the step part 24 for superposition is determined by the plate thickness of eaves gutter a' and the bonding on both sides so that the inner surfaces of eaves gutter a and a' are continuous and substantially flush with each other. The tape 25 is preset to a predetermined dimension in consideration of its thickness, etc.

The above-mentioned double-sided adhesive tape 25 may be any conventionally known tape as long as it has excellent metal adhesion, but for example, one that is highly flexible and followable, and has characteristics that are resistant to shrinkage, repeated stress, and thermal expansion is preferable. desirable.

Now, for the above eaves gutter a, the other adjacent eaves gutter
In order to connect a', after peeling off the release sheet (not shown) of the double-sided adhesive tape 25 previously attached to the inner joint surface of the polymerization step 24, The connecting part of the other eaves gutter a' is fitted into the stepped part 24 from above, and the eaves gutter a' is overlapped with the other eave gutter a'.
a' ear wrapping parts 21', 21' are connected to the engagement notch 2
2 and 22 are all that is required.

During this connection work, since eave gutter a and a' have elasticity, the ear wrap portions 21' and 21' of the other eave gutter a' expand the connecting portion of eave gutter a outward and guide the eaves gutter a. 23,
23 to the engagement notches 22, 22, so that the elastic engagement is ensured with one touch. Polymerized and adhered. Moreover, the inner edge 22a of the engagement notch 22, 22,
22a serves as a positioning stopper, so the end edges 21'a, 21'a of the ear wrapping parts 21', 21' of the other eaves gutter a' are connected to the engaging notches 22, 22.
The eaves gutters a and a' can be accurately connected in a straight line simply by butting against the inner edges 22a and 22a of the eaves troughs a and a'.

After the eaves gutters a and a' are connected as described above, the inner surfaces of the adjacent eaves gutters become continuous and substantially on the same surface without any step due to overlap, and Since the double-sided adhesive tape is sandwiched and protected within the polymerization step, the adhesive tape will not be attacked by rainwater, dirt, etc. that have fallen into the eaves gutter. Further, the double-sided adhesive tape 25 is extremely convenient because it not only adheres the eaves gutters a and a' but also acts as a seal to prevent water leakage from the connecting portions.

Incidentally, since the engaging notch 22 and the guide piece 23 are not visible from below, the appearance does not deteriorate.

Further, in this embodiment, the eaves gutter was explained as being made of metal, but the invention is not limited to this, and it can also be applied to eaves gutter made of a material other than metal, for example, resin such as vinyl chloride. The present invention can be applied not only to ordinary eaves gutters but also to curved gutters installed at the corners of houses.

(Effects of the present invention) As described above, the present invention provides an eaves gutter having an ear wrap portion formed on both sides in the longitudinal direction from the outside to the inside. An engagement notch is provided by cutting out a predetermined length in the longitudinal direction of the end of the inlet and approximately symmetrically so that the end of the selvedge part of the other adjacent eave gutter fits and locks, and the notch has an upper outer side cutout. A guide piece extending in a curved shape toward is configured such that it engages resiliently, and
At the joint where adjacent eaves gutters overlap, a step for overlapping is formed that bulges outward, and a double-sided adhesive tape is interposed between the joining surface of the step and the other eaves gutter. When the eaves gutters are connected, the inner surfaces of the adjacent eaves gutters form a continuous, substantially flush surface. Therefore, when connecting the eaves gutters, it is necessary to By simply press-fitting the ear wrap portion of the other eaves gutter downward, the ear wrap portion is accurately guided into the engagement notch along the guide piece while expanding the connecting portion of one eave gutter outward. This makes positioning easy and the ear wrap part can be reliably spring-fitted into the notch.This allows for one-touch construction at the construction site without the use of tools or the need for special techniques or skills. Eaves gutters can be connected easily and accurately.

In addition, the engaging part and the overlapping step part need only be provided at one end in the longitudinal direction of the eaves gutter, and can be integrally formed by press working in the eaves gutter manufacturing process, so it is not only easy to manufacture. Since extra members such as conventional connecting rods are not required, costs can be reduced.

Furthermore, according to the present invention, since the connecting portions are bonded with double-sided adhesive tape, the eaves gutters can be reliably joined by simply pressing the connecting portions together, and the double-sided adhesive tape provides a seal at the overlapping portions of the eaves and gutters. Since this function is achieved, it is possible to omit the step of bonding the connecting portions by soldering or the like as in the conventional method, and workability can be greatly improved. Moreover, after connection, the inner surfaces of adjacent eaves gutters are continuous and approximately flush with each other without any step due to overlap, and the entire surface of the double-sided adhesive tape is covered between the eaves gutters and protected from the outside. This prevents the double-sided adhesive tape from being damaged by rainwater or debris flowing through the eaves gutters, and the adhesive strength of the double-sided adhesive tape does not weaken, improving durability. , it is possible to reliably prevent water from leaking from the connection part or peeling off of the connection part. In addition, since there is no step difference due to overlap between the inner surfaces of the eaves gutters, the eaves gutters can be installed freely without being affected by the direction of rainwater flow, which further improves work efficiency. Although it is simple, it produces extremely useful practical effects.
