Description

Title of the invention: Multifunctional bicycle luggage rack.

[0001] The present invention relates to a device for transforming a classic bicycle into a cargo bike in a few minutes thanks to a multifunctional luggage rack [Fig.1] [Fig.5].

[0002] Currently, there are various transport solutions available for bicycles: rear rack, front rack, child seat or saddle. The present invention allows these three transport solutions to be combined using a simple and quickly removable device.

[0003] This invention offers an alternative to the cargo bike by providing a solution that is practical, economical and ecological:

[0004] - Practical: the device can be installed and removed in a few minutes depending on The product's dimensions also allow for easy storage and transport, depending on the user's needs (traveling alone, with one child, two children, one other person, or transporting goods). A version that can be disassembled using recycled bicycle frames will also be available.

[0005] - Economical: very few families can afford to buy a cargo bike in The price is a major factor, especially compared to an electric car. The device will be very affordable and compatible with most bicycles on the market.

[0006] - Ecological: access to city centers and low-emission zones will be Less and less possible by car. This invention encourages soft mobility for all daily journeys (going shopping, taking children to school, going to work...).

[0007] The device according to this invention makes it possible to encourage soft mobility by providing a simple, practical, economical and ecological solution for all daily journeys.

[0008] The device makes it possible to transform a classic bicycle into a cargo bike in a few minutes:

[0009] - The base is composed of a tubular assembly with two lateral tubes Positioned longitudinally on the bicycle, the perfectly straight, parallel tubes are spaced 100mm apart. Each tube has a diameter of 25mm and a length of 1250mm. To maintain the 100mm spacing between the two tubes and to join them, a 25mm diameter, 100mm long tube is welded perpendicularly to the middle of each tube. This tube acts as a spacer.

[0010] - A front loading platform (dimensions: 250mm x 150mm x 15mm) and a rear loading platform (dimensions: 500mm x 150mm x 15mm) complete the system. They fit between the two tubes that make up the base. The front platform is positioned 150mm from the front end of the tubes and secured by welding. The rear platform is positioned 0mm from the rear end of the tubes and secured by welding.

[0011] - Three fixing points allow the device to be mounted on the bicycle: the tube of saddle, front fork and rear wheel axle or luggage rack.

[0012] Fixing 1: a stem allows the device to be fixed to the seat tube. This stem consists of two axial ends fitted with clamping rings, fixed on one side to the tube serving as a spacer and on the other to the seat tube. [Fig.2].

[0013] Mounting 2: A threaded sleeve and bolt system with a jaw allows the device to be attached to the front fork. The system is welded perpendicularly and underneath to the front end of each tube. Tightening the bolts allows the distance between the jaws to be adjusted to firmly clamp the bicycle frame at the front fork [Fig. 3]. Mounting 3: Adjustable rods allow the device to be attached to the rear wheel axle or the luggage rack.

[0014] This technical solution stiffens the bicycle frame and ensures ideal weight distribution between the front wheel, the seat support, and the rear wheel, allowing the transport of several people and / or equipment within the maximum permissible weight of the bicycle (MVW). A front loading platform (dimensions: 250mm x 150mm x 15mm) and a rear loading platform (dimensions: 500mm x 150mm x 15mm) complete the system, enabling the easy attachment of numerous accessories [Fig. 4]: seats, child seats, footrests, front rack, two-seater saddle, seat cushions, footrests, child safety barriers, lights, surfboard rack, panniers, top case, shipping box, etc.

[0015] The attached drawings illustrate the invention:

[0016] - Fig. 1 represents the complete device of the invention.

[0017] - Fig. 2 represents the fixing system on the seat tube.

[0018] - Figure 3 shows the mounting system on the frame at the fork Before.

[0019] - Fig. 4 represents the front and rear loading platforms.

[0020] With reference to these drawings, the device comprises:

[0021] - Base: two parallel tubes spaced 100 mm apart. The diameter of each tube is 25mm in diameter and 1250mm in length. To maintain the 100mm gap between the two tubes and to join them, a 25mm diameter, 100mm long tube is welded perpendicularly to the middle of each tube. This tube acts as a spacer.

[0022] - Attachment 1: a stem allows the device to be attached to the saddle. This- It is fixed on one side to the tube serving as a spacer and on the other to the seat tube. [Fig.2]

[0023] - Fastening 2: A threaded sleeve and bolt system with jaw allows the The device is attached to the front fork. The system is welded to the front end of each tube perpendicularly and underneath. Tightening the bolts allows adjustment of the distance between the jaws to firmly clamp the bicycle frame at the front fork [Fig.3].

[0024] - Platforms: a front platform (dimensions: 250mm x 150mm x 15mm) (6) and a rear platform (dimensions: 500mm x 150mm x 15mm) (7) complete the device in order to be able to easily attach many accessories [Fig.4].

[0025] The device according to the invention is particularly intended to facilitate the transport of people and / or equipment on a bicycle.
