Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a gutter attachment.

(Prior art) As a gutter attachment device that makes it possible to easily install and remove a gutter by utilizing the deflection of a spring body, for example, Japanese Utility Model Application Publication No. 16358/1983 or No. 79536/1989 discloses There is an idea described in .
In all of these devices, gutter ear holding parts are connected to both ends of the support, a spring body is attached to the lower surface of the support, and the gutter ear holding parts and this spring body are used to hold the gutter ears. It is designed to support. In the device described in the former publication, the spring body is composed of a pressing spring having a rolled arc-shaped bent portion at the lower part,
This roll-wound arc-shaped bent portion is made to come into elastic contact with the inner edge of the gutter ear, and in the device described in the latter publication, the spring body is composed of a flat spring having folded portions at both ends. is similarly made to come into elastic contact with the inner edge of the gutter ear.

However, these gutter attachments are configured such that the spring body is bent inward in the width direction of the gutter and exhibits its springiness outward in the width direction of the gutter.
For this reason, if an external force is applied inward in the width direction of the gutter, such as when a ladder is hung on the gutter, the spring body may bend and the gutter may come off. This situation is particularly noticeable when a spring body with a small spring constant is used. Therefore, this type of gutter attachment requires a strong spring constant to ensure gutter retention.

However, if you increase the spring constant in this way,
A large force is required to attach and detach the gutter, and on the contrary, it becomes difficult to take advantage of the advantage of the spring-equipped gutter mount, which is that the gutter can be easily attached and detached.

(Purpose) The present invention was developed in view of these problems, and its purpose is to reduce the external force applied inward in the width direction of the gutter even when a spring body with a small spring constant is used. It can hold the gutter sufficiently. The object of the present invention is to provide a gutter fixture that is easy to install and remove.

(Structure) In order to achieve the above object, the present invention forms gutter ear holding parts at both tips of a gutter support whose both ends are formed upright, and the gutter ear holding parts are formed on the lower surface of the gutter support. In a gutter attachment device in which the spring bodies are mounted facing each other and the gutter ears are supported by the gutter ear holding part and the spring body, the spring bodies are fixed to the flexible piece and the gutter support. The flexible piece is made of a bent plate spring material with a cross section roughly in the shape of a dogleg, and the flexible piece has a locking part rising up from one end thereof, and this locking part is held in the gutter ear. The spring body is attached to the gutter support between the gutter ear holding part and the above-mentioned rising part so as to face the gutter ear holding part, and the gutter ear The feature is that the parts are held in place.

(Example) Hereinafter, the present invention will be described in detail based on an illustrated example.

1 to 3 show an embodiment of a gutter attachment device according to an embodiment of the present invention. In the figures, reference numeral 1 denotes a gutter support plate, which has rising portions 2 at both ends. The tip of the portion 2 is bent to have a U-shaped cross section to form a gutter selvage holding portion 3. A falling piece 5 is attached to one end of the gutter support plate 1 for attaching this gutter attachment to a rafter or the like of a house (see FIGS. 1 and 2).

Reference numeral 4 denotes a spring body made by bending a metal plate into a substantially square cross section, one piece of which is configured as a mounting piece 4b that is fixed to the lower surface of the gutter support plate 1, and the other piece is configured to be attached to this mounting piece 4b. It is configured as a bending piece 4a that bends elastically. A bent portion 4c between the attachment piece 4b and the flexible piece 4a is curved to have an arcuate cross section, thereby ensuring the elasticity of the flexible piece 4a. At one end of the flexible piece 4a, a locking part 4d is integrally formed and rises along the edge thereof and is gently curved outward (see FIG. 3).

The spring body 4 is configured such that the locking portion 4d of the flexible piece 4a faces the gutter selvage holding portion 3 of the gutter support plate, and the attachment piece 4b is attached to the top plate 3a of the gutter selvage holding portion 3.
It is fixed to the lower surface of the gutter support plate in the vicinity of the rising portion 2 that is continuous with the gutter support plate. Therefore, the spring body 4 has a spring property in the vertical direction of the gutter support plate 1, and the locking part 4d and the gutter ear holding part 3
The gutter ear is held by the hanging part 3b (see Figures 1 and 2). Further, the spring bodies 4, 4 located at both ends of the gutter support plate 1 are attached in opposite directions in the width direction of the top plate 3a of the gutter ear holding portion 3.

Therefore, in the gutter mounting tool described above, the gutter support plate 1
When the gutter is lifted from below and pressed against the flexible piece 4a of the spring body 4 while slightly bending the gutter ear part inward in the width direction, the flexible piece 4a bends upward and the space necessary for entering and exiting the gutter ear part is created. The gutter ear portion is a flexible piece 4a.
It slides into the gutter selvage holding part 3 while being guided by. When the gutter ear part slides into the holding part 3 side, the flexible piece 4
a returns downward due to its elasticity, and the gutter ear portion is held by the locking portion 4d and the hanging portion 3b of the gutter ear holding portion 3.

In this embodiment, since the locking portion 4d is formed to be gently curved outward, that is, toward the hanging portion 3b of the gutter selvage holding portion 3, the gutter selvage 4d is formed to be gently curved toward the hanging portion 3b of the gutter selvage holding portion 3 in the above operation. With less frictional resistance on the sides, it slides smoothly, making installation and removal of the gutter even easier.

Furthermore, when a ladder or the like is hung on the gutter attached to the gutter ear holding part 3 in this way, force is applied inward in the width direction of the gutter, but this force is applied by the locking part 4d of the spring body 4. Since the flexible piece 4a is not bent in the vertical direction, there is no need to worry about the gutter coming off.

Moreover, in this embodiment, as shown in FIGS. 1 and 2, the spring body 4 has a rising portion that connects the other side edge of the flexible piece 4a that does not have the locking portion 4d with the lower surface of the gutter support plate. Since the flexible piece 4a is attached so as to be in contact with the outer surface of the gutter, the flexible piece 4a acts as a support against the force applied inward in the width direction of the gutter, and even when such acting force is large. It can hold the gutter securely.

(Effects) As described above, according to the present invention, the spring body that clamps the gutter ear together with the gutter ear holding portion is made of a plate spring material having a substantially doglegged cross section and consisting of the mounting piece and the bending piece. The mounting piece of the spring body is attached to a predetermined position on the lower surface of the gutter support so that the bent part with the bending piece is parallel to the side edge of the gutter support.
By deflecting the deflection piece in the vertical direction of the gutter support, the gutter can be easily installed or removed.

In addition, a locking piece is formed on the flexible piece at its side end facing the hanging piece of the gutter ear holding part, and this locking piece comes into contact with the inner surface of the ear of the gutter and cooperates with the hanging piece. Once the gutter is installed, even if an external force is applied to the gutter from the width direction, this external force acts in the direction of the end surface of the spring body through the locking piece, and the flexible piece The entire spring body acts as a support without bending and can reliably support the gutter. Therefore,
Since the gutter is not supported by the spring force of the spring body, the gutter can be supported regardless of the spring constant.
