Summary of the Invention
Problems to be Solved by the Invention
[0004] This had the following drawbacks. (a) When the fallen leaves accumulate and become full, raindrops fall outside and the rain gutter no longer functions. (b) Even for the type installed on the upper part of the rain gutter, if the mesh is made fine, fallen leaves will enter the gaps and block the raindrops, and the rain gutter will no longer function. If the gaps are made wide, fallen leaves will enter the rain gutter and accumulate inside. (c) In order to safely remove the fallen leaves in the rain gutter, it is necessary to set up a scaffold, which incurs high costs. (d) Workers climb onto the roof to clean the fallen leaves, which is a dangerous operation involving the risk of falling. The present invention has been made to eliminate the above drawbacks.
Means for Solving the Problems
[0006] (i) When attaching the leaf basket (1) to the rain gutter (3), using the tip (5) of the eccentric projection (2) of the leaf basket as a pivot point allows the roof (6) side to sag due to gravity, preventing it from hitting the edge (7) of the roof, and thus enabling insertion. It can be attached in the predetermined position following the shape of the rain gutter (3). (This is referred to as the self-alignment effect.) (Figures 1, 2, and 3) (b) The eccentric projection (2) and connecting part (9) of the leaf basket (1) can be integrated and their length and shape can be selected to allow for easy attachment and detachment using the alignment bar (10). For example, a special tool consisting of a stick with a bifurcated tip and a hook (like a jitte) attached to the end can be used to attach and detach the leaf basket (1). (h) Leaves can be safely removed without having to erect expensive scaffolding. (ii) In areas where fallen leaves tend to accumulate, leaf removal can be repeated several times a year. (e) Leaves do not accumulate and damage the gutters, allowing the gutters to be used for a long period of time. (H) Dead leaves will accumulate in the rain gutter, preventing raindrops from leaking outside. (T) Leaves do not accumulate in the drip-collecting section of the rain gutter, preventing blockage.

[0008] Embodiments of the present invention will be described based on the contents shown in Figures 1 to 4. The self-aligning leaf basket (1) has a net (11) to catch fallen leaves and can be installed inside the rain gutter (3). It has an eccentric projection (2) that is angled on the opposite side from the roof, similar to the shape of the rain gutter, and is characterized by the phenomenon that when the alignment bar (10) is lifted, the tip (6) on the roof (4) side lowers. It is safe and inexpensive to attach and detach, and can be used to clean up fallen leaves repeatedly. If a leaf basket (1) that is similar in shape to a rain gutter is attached to one end of the rain gutter and has an inclined eccentric projection (2), the leaf basket will tilt due to gravity. The basic principle is to position the rain gutter approximately in the center of the lower part of the roof's edge (7), and to install it below the extension of the roof's slope. The leaf basket tip (6) is inserted into the gap between the roof edge (7) of the rain gutter and the lower part of its extension (8), and gravity allows it to be installed in the same position on the rain gutter, which is possible as a self-alignment effect.

Claims
1. A self-aligning leaf basket to be installed inside a rain gutter, A self-aligning leaf basket comprising a leaf basket (1), an eccentric projection (2) and a connecting part (9) angled to the end of the leaf basket (1) opposite to the leaf basket alignment tip (6), and an alignment bar (10) attached to one end of the connecting part (9), which generates a self-aligning effect so that when inserted between the roof tip (7) and the rain gutter tip (8), the leaf basket (1) can be installed inside the rain gutter by the gravitational force of the leaf basket (1).
2. The self-aligning leaf basket according to Claim 1, wherein the angle required for the self-aligning leaf basket to self-align is the sum of the angle θ in (1) and the angle α in (2) below: (1) the angle θ between the vertical reference line of the self-aligning leaf basket and the eccentric projection (2) (2) the angle α between the eccentric projection (2) and the connecting part (9) The sum of angle θ and angle α is in the range of 0° to 135°.
