Abstract

To provide a self-aligning leaf cage having a configuration for being attached to and detached from a rain gutter so that the leaf cage can be efficiently used for repeatedly removing fallen leaves accumulated in the rain gutter.SOLUTION: The leaf cage has an eccentric protrusion and a connecting portion at one end, allowing repeated clean-up of leaves that have accumulated in a rain gutter. The eccentric protrusion and the connecting portion allow for self-aligning structure between a roof and the rain gutter, making it safe and easy to attach and detach.

Description

[Technical field]

[0001] The present invention relates to a basket that is attached to clear leaves that accumulate in rain gutters. [Background technology]

[0002] Traditionally, the most common method of preventing leaves from falling into gutters was to install leaf covers, and various types of covers had been devised and installed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Actual publication Showa 59-057633 [Patent Document 2] JP 8-338110 [Patent Document 3] Application Publication No. 5-83138 Summary of the Invention [Problem to be solved by the invention]

[0004] This had the following drawbacks: (i) When fallen leaves accumulate and fill the gutter, raindrops fall onto the outside and the gutter no longer functions properly. (b) Even with the type that is installed on the top of the gutter, if the mesh is fine, fallen leaves will get into the gaps and block raindrops, causing the gutter to no longer function. On the other hand, if the gaps are too large, fallen leaves will get into the gutter and accumulate inside. (c) In order to safely remove fallen leaves from gutters, it is necessary to set up scaffolding, which incurs high costs. (2) Workers climb onto roofs to remove fallen leaves, which is dangerous work that involves falling. The present invention has been made to eliminate the above-mentioned drawbacks. [Means for solving the problem]

[0005] The self-aligning leaf cage (1) is fitted with a net (11) for catching fallen leaves and can be installed inside a rain gutter (3). It has an eccentric protrusion (2) similar to that of a rain gutter and angled on the opposite side to the roof side, and is characterized by the phenomenon that when the alignment bar (10) is lifted, the tip (6) on the roof (4) side drops down. It is safe and inexpensive to attach and detach, and can be used to repeatedly clean fallen leaves. Effect of the Invention

[0006] (a) When attaching the leaf cage (1) to the gutter (3), if the tip (5) of the eccentric projection (2) of the leaf cage is used as a fulcrum, the roof (6) side will lower due to gravity and the cage can be inserted without hitting the roof tip (7). It can be attached to the desired position by following the shape of the gutter (3). (This is considered to be a self-alignment effect.) (Fig. 1, Fig. 2, Fig. 3) (b) The eccentric projection (2) of the leaf cage (1) and the connecting portion (9) can be easily attached and detached by using an alignment bar (10) by selecting the integral structure, length, and shape. For example, a special tool with a fork at the end of a stick with a hook (shaped like a truncheon) on the end can be used to attach and detach a leaf cage (1). (c) Fallen leaves can be removed safely without the need for expensive scaffolding. (2) In areas where leaves tend to accumulate, it is possible to remove leaves several times a year. (e) The gutters can be used for a long time without damage caused by fallen leaves accumulating. (e) Dead leaves accumulate in the gutters, preventing raindrops from leaking out. (d) Fallen leaves do not accumulate in the drip tray of the gutter and cause clogging. [Brief description of the drawings]

Claims

1. This self-aligning leaf cage (1) is installed inside a gutter and has an eccentric protrusion (2) with an angle at one end and a connecting part (9) attached, so that it can be inserted between the roof tip (7) and the gutter tip (8) by the action of gravity with the alignment bar (10) as a fulcrum.

2. The angle required for the self-alignment leaf cage (1) to self-align is (1) the angle θ between the vertical reference of the leaf cage (1) and the leaf cage eccentric protrusion (2). (2) Angle α between the leaf basket eccentric projection (2) and the connecting part (9) The angle (θ+α) according to the present invention is in the range of 0° to 135°.
