DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spring screw, and more particularly to a spring screw for attaching a component to an inclined surface.

[0002]

2. Description of the Related Art A conventional spring screw will be described in detail with reference to the drawings.

FIGS. 5A and 5B are a side view and a sectional view showing a first conventional example. (For example, Japanese Patent Publication No. 06-6
No. 5098). The spring screw 120 shown in FIGS. 5A and 5B is a substantially cylindrical conductor, and a spring portion 122 having a diameter gradually reduced toward one end is integrated with one end of the outer peripheral screw portion 121 at the center. The spring portion 122 has a notch 123 in the axial direction from the tip.

Further, a hollow hole 126 penetrating the spring portion 122, the outer peripheral screw portion 121, and the short cylindrical portion 125 is provided.
The diameter gradually becomes smaller toward the tip.

FIG. 6 is a perspective view showing a second conventional example, and FIG. 7 is a side view showing an example of use of FIG. (For example, see
8-165,763).

[0005] Conventionally, there are various types of eave gutter hanging tools. On the other hand, some eaves such as a nose shield for attaching eave gutter hanging tools are almost perpendicular to a sloped roof, and others are vertical. In addition, even in the case of an eaves that is provided almost at right angles to the roof, the slope of the roof is 3 degrees.
Since there are various sizes, such as a size and a size, the inclination of the eaves is not constant.

As described above, since the inclination of the eaves is not constant, the angle between the mounting surface of the mounting portion of the eaves hanger attached to the eaves and the body of the hanger is changed in accordance with the inclination of the eaves. Preferably, the body is kept substantially horizontal so that it is susceptible to rainwater falling from the roof. As an eaves gutter hanging device capable of changing the angle between the mounting portion and the hanger main body as described above, an eaves gutter hanging device described in Japanese Utility Model Laid-Open No. 1-114733 is known.

[0007] The eave gutter hanging device is attached to the eave as follows. In other words, when attaching the eave gutter hanging device to the eaves that are almost perpendicular to the sloping roof, the surface where the eave gutter attachment device is attached and the surface where the eave gutter attachment device is installed The angle made is almost equal to the inclination of the roof, and the mounting part of the eave gutter hanging tool is attached to the eaves with the jig interposed. Then, even if the surface to be attached to the eaves is inclined, the surface to which the attachment for the eaves gutter is attached becomes almost vertical, and the eaves gutter can be attached without any trouble.
In addition, in the case where the eaves are attached to a substantially vertical eave, a mounting portion of the eave gutter suspension is directly attached to the eave without using a jig.

However, in the eaves gutter suspension described in the above publication,
In different buildings, for example, with a roof slope of 4 or 5 inches, change the jig to match the roof slope each time.
It is necessary to attach the eaves gutter to the eaves with this jig interposed. Therefore, in order to adapt to roofs having various slopes, it is necessary to prepare various types of jigs having different angles, which is inconvenient.

In FIG. 6 and FIG. 7, reference numeral 1 denotes an eaves gutter suspender, and the eaves gutter suspender 1 comprises a fixture 2, a suspender main body 3, and an angle adjusting member 9. The fixture 2 includes a mounting portion 4, a support rod 5, and a rotating rod 6. The mounting portion 4 is a plate-like body along the eaves, and has four through holes 43 for easy attachment to the eaves. The support rod 5 is a column integrated with the mounting part 4 and protrudes almost perpendicularly to the outdoor side of the mounting part 4.

The rotating rod 6 has a cylindrical shape, and a through hole is provided at the base thereof. A projecting piece provided at the tip of the support rod 5 is inserted into the through hole, and a wing nut 52 is screwed from above. The rotating rod 6 is mounted so as to be rotatable about the supporting rod 5 in a state where the rotating rod 6 is bent in a direction substantially perpendicular to the supporting rod 5. In addition, a locking plate 61 is integrally provided at a central portion of the rotating rod 6 in a substantially right angle direction. Further, a screw is drilled at the tip of the locking plate 61 to form a screw portion 62.

The hanging body 3 has an outdoor ear holding portion 31 provided at the tip, an indoor ear holding portion 32 provided on the indoor side of the outdoor ear holding portion 31, an outdoor ear holding portion 31, and an indoor ear. A through hole 33 provided between the holding portion 32 and the holding portion 32
Consists of The outdoor-side ear holding portion 31 is formed so that the tip protrudes upward. The outdoor-side ear holding portion 31 is inserted into the outdoor-side ear of the eaves gutter to hold the outdoor-side ear of the eaves gutter.

The indoor ear holding portion 32 is composed of two locking pieces 36 and 37 projecting from the lower surface, between which the ear of the eave gutter is inserted to hold the indoor ear of the eave gutter. Through hole 33
Is provided to penetrate from the upper surface to the lower surface.

The angle adjusting member 9 comprises an upper cylindrical locking piece 91 and a lower cylindrical locking piece 92. The upper cylinder locking piece 91 is a cylinder, the upper surface 93 is a surface substantially perpendicular to the center axis of the cylinder, and the lower surface 94 is a surface inclined with respect to the center axis of the cylinder. A through hole 95 is provided in the cylindrical central axis. The lower cylinder locking piece 92 is a cylinder and has an upper surface 96.
Is a surface inclined with respect to the central axis of the cylinder, and the lower surface 97 is a surface substantially perpendicular to the central axis of the cylinder. A so-called mortar-shaped through-hole 98 is provided on the center axis of the cylinder and extends downward.

Reference numeral 7 denotes a spring spring, and reference numerals 71 and 72 denote washers mounted above and below the spring 7. 75 is a wing nut. Numeral 8 denotes a roof, and numeral 85 denotes an eave almost perpendicular to the roof 8. Reference numeral 86 denotes an eaves gutter, 87 denotes an outer ear of the eaves gutter 86, and 88 denotes an inner ear of the eaves gutter 86.

Next, a method of attaching the eaves gutter hanging tool 1 and an eaves gutter will be described. First, the mounting portion 4 of the fixture 2 is set along the eaves 85, and a screw is screwed into the eaves 85 from the through hole 43 to attach the eaves gutter 1 to the eaves 85. Next, the angle of the hanger main body 3 is adjusted.

The adjustment of the angle is performed as follows. First,
The upper column locking piece 91 and the lower column locking piece 92 are relatively rotated. Then, the lower surface 94 of the upper cylindrical locking piece 91 is inclined, and the upper surface 96 of the lower cylindrical locking piece 92 that is in contact with the lower surface 94 is also inclined. The position changes, and the total length of the outdoor length of the upper cylinder locking piece 91, the outdoor length of the lower cylinder locking piece 92, the indoor length of the upper cylinder locking piece 91, and the lower cylinder The total length of the indoor side length of the stopper piece 92 changes, and as a result, the lower surface 9 of the lower locking piece 92 which is the tip end
7 changes, and the direction of the hanger main body 3 in contact with the lower surface 97 changes.

When the upper and lower cylindrical locking pieces 91 and 92 are relatively rotated, the lower surface 94 of the upper cylindrical locking piece 91 and the upper surface 96 of the lower cylindrical locking piece 91 are inclined. Therefore, the extension of the through-hole 95 at the center of the upper cylinder locking piece 91 does not pass through substantially the center of the lower cylinder locking piece 92, but in the present invention, the through-hole of the lower cylinder locking piece 92 98
Is formed in a mortar shape whose diameter increases toward the bottom, so that the threaded portion of the rotating rod 6 that is passed through the through hole 95 of the upper cylindrical locking piece 91 and the through hole 98 of the lower cylindrical locking piece 92 6
2 moves in the mortar-shaped through-hole, and can relatively rotate the upper column locking piece 91 and the lower column locking piece 92 without any trouble. Further, when the angle of the hanger main body 1 changes, the nut 75 screwed from below becomes difficult to follow the lower surface of the hanger main body 1, but a spring spring 7 is provided between the hanger main body 1 and the nut 75. Therefore, the spring 7 absorbs the change in the angle.

Next, the rotating rod 6 is rotated about the supporting rod 5 to correct the horizontal angle of the hanging body 3.
That is, when the upper and lower cylinder locking pieces 91 and 92 are relatively rotated to change the angle of the hanging body 3 in the indoor and outdoor directions, the angle in the left and right direction inevitably changes. The angle of the hanging body 3 in the left-right direction is corrected by rotating the rod 6. At this time, in the present invention, since the rotating rod 6 is rotatably attached to the supporting rod 5, the rotating rod 6 can be rotated without any trouble.

After adjusting the angle in this manner, the outdoor ear 87 and the indoor ear 88 of the eave gutter 86 are held by the outdoor ear holding portion 31 and the indoor ear holding portion 32 of the hanging tool main body 3, respectively. Attach 86. After the eaves gutter 86 is attached, if it is found that the angle is not appropriate, the upper column locking piece 91 and the lower locking piece 92 are relatively rotated again or the rotating rod 6 is rotated to set the angle. You only have to correct it.
