Abstract

PURPOSE: To provide a roof for a bicycle which can be simply attached to the bicycle, and can prevent from exposure to rain water as a front view is secured, and absorbs wind pressure softly to wind coming from a back side for reducing the possibility of falling down. CONSTITUTION: A roof for a bicycle is composed of two elastically deformable columns 1 which extend about in parallel to each other and have such length as at least the front of a rider on a bicycle 2 can be covered; a roof sheet 7 provided extendingly between the columns 1; and an attaching cord 4 to connect the roof sheet 7 to the column 1, and the attaching cord 4 can be freely drawn out in the longitudinal direction so as to elastically deform the column 1 in line with the side edge form of the roof sheet 7 for mutually joining the roof sheet 7 and the column.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof mounted on a bicycle to prevent rain.

[0002]

2. Description of the Related Art Conventionally, when a bicycle is used in the rain, an umbrella is opened and held with one hand while operating a handle with the other hand. This is unfavorable for safety because the handlebar operation of the bicycle becomes extremely unstable and the front view is obstructed by the umbrella.

[0003]

SUMMARY OF THE INVENTION The present invention can be easily attached to a bicycle, can block rain while securing a front view, and can flexibly absorb wind pressure from the wind from the rear. The purpose is to provide a roof for bicycles that reduces the risk of falling due to wind.

[0004]

Means for Solving the Problems In order to solve the above-mentioned problems, the means adopted by the present invention is elastically deformed so as to extend substantially in parallel and have a length capable of covering at least the front surface of a cyclist. It consists of two free columns, a roof sheet stretched between the columns, and an attachment string that connects the roof sheet and the columns, and the attachment string is elastic in the shape of the side edge of the roof sheet. It is characterized in that it can be drawn out in the longitudinal direction so that it can be deformed to connect the roof sheet and the pillar.

Further, the roof sheet has a triangular shape.

Also, the bases of the two columns are

[Outer 1] It is characterized in that they are connected to each other at a character-shaped connecting portion.

Further, the pillar is characterized in that it can be expanded and contracted.

Further, the roof sheet is made of a transparent sheet material.

Further, the base of the roof sheet is fixed to the base of the support column.

Further, the attachment string is inserted through an insertion hole formed in the roof sheet and a connecting ring movably inserted in the support column.

[0011]

[Operation] A folded roof sheet can be stretched over the columns to avoid rain while riding a bicycle. Wind pressure from the rear can be absorbed by the elasticity of the columns to prevent falls.

[0012]

According to the present invention, it is possible to provide a roof while riding a bicycle to avoid wind, and since the roof sheet is transparent, it is possible to secure a front field of view and it is safe.
In addition, wind pressure from the rear is absorbed by the elasticity of the columns, and accidents such as falls can be prevented. The roof sheet and columns can be folded so that they do not interfere with running when not in use.

[0013]

The preferred embodiments of the present invention will be described in detail below. In the figure, (1) is a column whose base is fixed to the front part of the bicycle (2). The pillar (1) is 40-60c
Two of them are arranged in parallel with each other at an interval about the shoulder width of a human being of m, and are elastic and flexible as well as elastic. As such a column, for example, a fishing rod made of glass fiber can be used, and it is contracted when not in use. The support (1) is fixed to, for example, a shopping basket (3) attached to the front part of the bicycle (2), and the support (1) is detachable together with the shopping basket (3) as required. The tip of the pillar (1) is stretched on the luggage carrier (5) of the bicycle (2) by the pull-out end of the attachment string (4) that connects the roof sheet (7) and the pillar (1) described below, and due to its elasticity. It is held in a predetermined curved shape. The attachment string (4) is made of a wire material having high lubricity, such as fishing tackles, and enables a smooth withdrawal when connecting the roof sheet and the column.

A plurality of connecting rings (6) which can move along the supporting column (1) are attached to the supporting column (1), and the connecting ring (6) is attached.
While the attachment string (4) is slidably inserted into (6),
The attachment string (4) is inserted through the insertion hole (8) formed in the roof sheet (7). As shown in FIG. 2, the roof sheet (7) is formed in a triangular shape in which the width of the central portion is slightly widened and the width is gradually narrowed toward the longitudinal ends of the columns, and the length is 150 to 180c.
m is suitable.

The base end of the roof sheet (7) is wound around a folding piece (9) and fixed to the column (1), and the tip is free. As shown in FIG. It can be folded between 1) and covered with a cover (10).

The base of the column (1) is preferably as shown in FIG.

[Outer 1] They are integrally connected by a character-shaped connecting portion (11) and fixed to a front portion of the shopping basket (3) with a mounting bracket (12).

As shown in FIG. 9, the support column (1) is made of a flexible tube, and is contracted when not in use as shown in FIG. 6, and the roof sheet (7) is folded between the contracted support columns (1). Together with the cover (10). The roof sheet (7) is not limited to the triangular shape shown in the figure, and it goes without saying that it may be an elongated rectangular shape.

When the bicycle (2) is used in the rain, as shown in FIG.
As shown in 3, pull the roof sheet (7) together with the struts (1) that were folded, pull the attachment string (4) and squeeze it, and fix it at the tip of the struts (1) to stretch it. Can be done. Since the strut (1) has elasticity, when the wind pressure from the rear is received, the strut (1) can elastically bend and absorb the wind pressure, and prevent accidents such as the bicycle falling. You can When not in use, the attachment string (4) is removed from the bed and loosened to shrink the support column (1) while the roof sheet (7) is folded. After squeezing the attachment string (4) and pulling it out, when attaching it to a luggage carrier etc., its length can be adjusted to correspond to the height of the user.
