Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a bicycle luggage basket in which a part of the basket frame is replaceable.

(Prior Art) A bicycle luggage basket in which the bicycle housing is divided into two parts, a front frame member and a rear frame member, and the two parts are connected and fixed by a connecting member is already known from Publication of Utility Model Publication No. 54-21311. , the one described in the above publication consists of a front frame member consisting of a front part, both side parts and a cargo receiving part on the bottom, and a rear frame member consisting of a rear part, both side parts and a cargo receiving part on the bottom. Since the cargo receiving section is divided into two parts in the center, the strength of the entire structure including the bottom is weak, and both the front and rear frame members have complicated shapes, so they must be formed by pressing flat mesh frame members. However, there is a problem in that it is not possible to do so and the manufacturing cost is high. A known solution to this problem is the one described in Japanese Utility Model Publication No. 57-36537, which was proposed earlier by the applicant. The upright frame is integrated with the receiving frame and the rear upright frame, so
There is a problem in that the impact applied to the front frame at the time of a collision is directly applied to the connection points between the left and right upright frames and the rear upright frame, causing the entire basket to become distorted.

(Problem to be solved by the invention) The problem to be solved by the invention is to eliminate the problem of strength by making the bottom cargo receiving part a single piece, and to press the shape of the front and rear two members from a flat mesh frame member. As it has a simple shape that can be molded by hand, manufacturing costs can be reduced, and the problem is that the impact applied to the front frame in the event of a collision is applied directly to the connection point between the left and right upright frames and the rear upright frame, causing the entire basket to become distorted. Our objective is to provide an inexpensive bicycle luggage rack.

(Means for Solving the Problems) The bicycle luggage basket of the present invention, which has solved the above-mentioned problems, has a metal mesh plate welded inside a rectangular shape-retaining frame rod made of metal wire, and a shape-retaining frame rod made of metal wire. An L-shaped base frame member, which is formed by bending a mesh frame member formed by stretching a plurality of reinforcing frames at the center of the upper and lower sides of the frame and integrally connecting a rear frame part to the rear side of the cargo receiving frame part; A U-shaped peripheral frame member in which left and right side frame parts are integrally connected on both sides of a front frame part by bending a mesh frame member made by welding a metal mesh plate into a rectangular shape-retaining frame rod made of wire rod. A stop plate with bolt insertion holes welded to the center of the tip of the cargo receiving frame is attached to a stop plate with bolt insertion holes extending backwards from the center of the lower end of the front frame. The present invention is characterized in that it is removably connected to both sides of the rear frame portion of the base frame member by means of hooking members provided on the edges of the left and right side frame portions of the frame member.

(Example) Next, an example of the present invention will be described in detail based on the drawings.

Next, FIGS. 3 and 4 show a second embodiment of the present invention, and 1 shows a structure in which forward-facing sub-side frames 3a and 3a are stretched on both sides of the rear side of the receiving frame member 2. Rear frame part 3
The base frame member 1 is a rectangular shape-retaining frame rod 4 made of metal wire, and a metal mesh plate 5 commonly called expanded metal.
At the same time, four reinforcing frame metals 5a are welded to the center of the upper and lower sides of the shape-retaining frame rod 4, and girder rods made of the metal wire are also welded to the upper and lower parts of the rear frame portion 3. 3b, 3b are welded, and the extensions on both sides of the crossbeam rods 3b, 3b are formed into annular hooking member engaging portions 6, 6 bent in the horizontal direction, and this base frame member 1 is also flat. It is manufactured by bending and forming a net frame member into an L shape by pressing, and a stop plate 9 with bolt insertion holes 8 is welded to the center of the tip of the cargo receiving frame member 2, and furthermore, the four The end extensions of the reinforcing frames 5a on both sides of the reinforcing frames 5a are connected to the cargo receiving frame 2.
The guide frame 5b is bent and stands up on the outside of the tip to prevent the front frame part 11 of the peripheral frame member 10 (to be described later) from coming off forward. This is a stop plate with a bolt insertion hole 8 welded to the center of the tip. Reference numeral 10 denotes a peripheral frame member in which left and right side frame parts 12, 12 are integrally stretched on both sides of the front frame part 11, and the peripheral frame member 10 is a shape-retaining frame made of the same metal wire as the base frame member 1. It is manufactured by bending a flat mesh frame member in which a metal mesh plate 5 is welded to a rod 4a into a U shape using a press, and above the edges of both side frame parts 12, 12 of the peripheral frame part 10. Both side frame parts 1

(Function) In this structure, the stop plate 15 with the bolt insertion hole 16 extended rearward at the center of the lower end of the front frame part 11 of the peripheral frame part 10 is connected to the cargo receiving frame part 2 of the base frame part 1. Since it is attached to a stop plate 9 with bolt insertion holes 8 on the top surface, when it is attached to the front of the bicycle, the bottom of the cargo receiving frame 2 can be attached to the gate-shaped support frame rod provided at the front of the bicycle. Place it on the bolt insertion holes 1 of the stop plates 15 and 9.
When attached using bolts, washers, and nuts inserted through holes 6 and 8, the peripheral frame member 10 and the base frame portion 1 are firmly connected and fixed, so that they cannot be disassembled due to vibrations generated during driving. There is no such thing, and it can be conveniently used by storing luggage inside the basket like conventional bicycle luggage baskets, but the peripheral frame member 10 has a front frame part 11 and left and right side frame parts 12, 12 integrated. The hooking members 13, 13 at the edges of the left and right side frame portions 12, 12 are removably fitted into the hooking member engaging portions 6 on both sides of the rear frame portion 3 of the base frame member 1. Therefore, even if an impact is applied to the front frame portion 11 of the peripheral frame member 10 during a collision, the impact force will be dispersed and absorbed in the margin formed by the free fitting and removal, and the cage will not be distorted. There is no risk of it happening.
In addition, the L-shaped base frame member 1 has a metal mesh plate 5 welded inside a rectangular shape-retaining frame rod 4 made of metal wire, and a plurality of reinforcing frames 5a at the center of the upper and lower sides of the shape-retaining frame rod 4. In addition, the U-shaped peripheral frame member 10 also has a metal mesh plate 5 in a rectangular shape-retaining frame rod 4a made of metal wire.
It is a U-shaped mesh frame member made by welding a mesh frame member, which is a simple shape that can be formed by a simpler press operation than a flat mesh frame member.
It has the advantage of being mass-produced at low cost, and the bottom is L.
Since the receiving frame material is located only on the base frame member 1 side of the mold and is not divided into two parts, the entire structure including the bottom part has excellent strength.

(Effects of the invention) As is clear from the above explanation, the invention has the following effects:
The bottom cargo receiving frame is reinforced with multiple reinforcing frames to eliminate strength problems, and the shapes of the front and rear base frame members and peripheral frame members are pressed from flat mesh frame members. Since it has a simple shape that can be molded, manufacturing costs can be reduced, and the problem is that the impact applied to the front frame during a collision is applied directly to the connection point between the left and right upright frames and the rear upright frame, causing the entire basket to become distorted. In addition, by making only the base frame member common and manufacturing multiple types of peripheral frame parts and combining them, products with various designs can be easily obtained, which not only makes it possible to reduce costs but also improves product management. It also has the advantage of convenience, as the base frame member and peripheral frame member can be easily separated and combined, allowing them to be stored in the bicycle packing box. It has great practical value as it eliminates the problems of .
