Description

[Detailed Description of the Invention] The present invention relates to a gutter hanger, and particularly relates to a gutter hanger in which at least one end of the hanger board is raised and a gutter lug locking portion is bent from the raised end. .

In such a gutter hanging tool, when the gutter ear portion is locked to the gutter ear locking portion, the gutter ear portion may come off due to external force. Therefore, in order to prevent this, a technique disclosed in Japanese Utility Model Application Publication No. 54-129031 has been adopted. As shown in Fig. 1, this technique involves horizontally extending a spring bar 2 with one end fixed to a substrate 1.
This extending portion was bent into a state in which it could press the gutter ear portion that was locked to the gutter ear locking portion, and the bent end portion, which was the other end, was formed in the horizontal portion 4 of the gutter ear locking portion 3. It is inserted into the guide hole 5. This is a technique in which the presence of the spring bar 2 can prevent the gutter ear from coming off due to external force. However, in this technique, since the spring bar 2 extends horizontally toward the gutter ear locking portion 3, the spring rod 2 exceeds its elastic limit when inserting the gutter ear portion into the locking portion. If bent, there is a drawback that the function of preventing the gutter ear from coming off cannot be effectively performed. That is, when the spring bar is bent beyond its elastic limit, it no longer returns to its original horizontal state and tilts upward, so the gutter ears easily fall out through the bottom of the spring bar. That's what happens.

The present invention has been proposed with the main purpose of eliminating such drawbacks of the prior art.

Therefore, in the present invention, at least one end of the board is raised, the raised end is horizontally extended outward, and the extended end is bent downward and inward to form the gutter lug locking part. In the gutter hanging tool, an elastic locking piece insertion hole is formed in a rising portion that is approximately at the same height as the center of the vertical width of the gutter lug locking part, and the horizontal extension of the gutter lug locking part is an elastic locking piece guide hole is formed in the portion, and the elastic locking piece fixed to the outer surface of the rising portion extends through the insertion hole toward the inwardly bent edge of the gutter lug locking portion;
The gist is that it is raised upward from its extending end and is loosely inserted and guided into the guide hole.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. In FIG. 2, reference numeral 11 denotes a substrate with both ends 12 and 13 raised up, the raised ends extending outward horizontally 14 and 15, and the extended ends bent downward and inward 16, 17, 18 and 19 to form gutter lug locking portions 20 and 21. An L-shaped elastic locking piece 22 is provided on one of the gutter lug locking portions 20 in the same manner as the spring bar 3 shown in FIG.

The other gutter lug locking portion 21 is provided with a Z-shaped elastic locking piece 23 as shown in FIG. That is, first, an elastic locking piece insertion hole 24 is formed in the rising portion 13 located at approximately the same height as the center of the vertical width l of the gutter lug locking portion 21, and an elastic locking piece guide is formed in the horizontally extending portion 15. A hole 25 is formed, and an elastic locking piece 23 whose one end is fixed to the outer surface of the rising portion 13 extends through the insertion hole 24 toward the inwardly bent edge 19 of the gutter lug locking portion 21. The guide hole is protruded from the guide hole, raised upward from the extending end, and loosely inserted into the guide hole.

In implementation, the elastic locking piece 23 has lo in the figure longer than the vertical width l, and the locking point C of the elastic locking piece 23 is located slightly below the insertion hole 24, It is desirable to set the distance _l1 to a value in the range of 15 to 25 times the thickness of the elastic locking piece 23.

According to the above configuration, when inserting the ear portion 26 of the gutter into the gutter ear locking portion 21, the elastic locking piece 23 is inserted into the ear portion 26.
, it is rotated upwards as shown by the broken line around point O, and when the insertion is completed, it is restored to the state shown by the solid line again. Therefore, this elastic locking piece 23 can prevent the ear portion 26 from coming off.

By the way, let us assume that the elastic locking piece 23 is rotated beyond its elastic limit when inserting the ear portion, so that it can only be restored to the state shown by the chain line in the figure. In the conventional technology shown in Fig. 1, the spring bar faces diagonally upward in this case, so it can no longer perform the function of preventing the ear from coming off, but in the case of the present invention, it is restored to its original state. Even if this is not done, since the elastic locking piece 23 faces diagonally downward, it can still function as a retainer. Therefore, according to the present invention, there is an advantage that the function of preventing the ear from coming off can be maintained even if the ear is subjected to severe use such as being attached and detached many times. For convenience of explanation, it is assumed that the elastic locking piece 23 rotates around the O point when the ear part is inserted, but since there is a distance between the anchoring point C and the O point, it actually rotates around the C point, and in this case, the elastic locking piece 23 rotates around the O point. The points are somewhat displaced outwards. Therefore, the elastic locking piece 23 when inserting the ear part
Because the entire body bends elastically, it is very unlikely that it will be deformed beyond its elastic limit. Therefore, the service life is extremely long.

Since the gutter hanger according to the present invention is constructed as described above, even if the elastic locking piece is deformed beyond its elastic limit, the ability to remove the gutter ear portion will not deteriorate, so it can be used in extremely severe conditions. It has the useful effect of being able to withstand In the embodiment, both ends of the substrate 11 are raised, but the present invention can also be applied to a structure where only one end is raised. Moreover, the structure of the present invention can also be implemented at both ends of the substrate.
