AI Technical Summary
When a bicycle is towing a wheelchair, the up and down movement, left and right shaking, and twisting of the wheelchair are directly transmitted to the bicycle, making it difficult to drive smoothly.
The towing connection device uses springs mounted between the spring pedestals on both the bicycle and the wheelchair, allowing for flexible and balanced connection, reducing the transmission of unwanted movements.
This solution enables smooth bicycle operation by isolating the wheelchair's movements, enhancing safety by positioning the wheelchair as training wheels and facilitating quick evacuation during emergencies.

Abstract
Description
[Technical field]
[0001] This invention relates to a towing attachment device for towing a wheelchair with a bicycle or electric bicycle. [Background technology]
[0002] It is publicly known as a wheelchair towing device through a publication under application number 2020-2006.
[0003] Application 2020-2006 Summary of the Invention [Problem to be solved by the invention]
[0004] When a bicycle is towing a wheelchair, depending on the connection state, the vertical movement, lateral sway, and twisting of the towed wheelchair can be directly transmitted to the bicycle, making it difficult to ride the bicycle smoothly.
[0005] In the towing connection device, spring 3 is attached between the flat surfaces of spring base 1 and spring base 2. It is possible to connect with a single large spring, but considering balance and flexibility, a set of two springs is more effective than a set of four springs.
[0006] In addition to solving the problems mentioned above, the wheelchair wheels are on the outside of the rear wheels of the bicycle, so they act as training wheels and prevent falls like those of motorcycles. In addition, in the event of a disaster, elderly caregivers who do not own cars can easily evacuate patients in wheelchairs quickly and far away by bicycle. [Brief description of the drawings]

[0008] The implementation of the invention will be explained with reference to FIG. The spring base 1 is attached to the saddle post of the bicycle via a mounting fixture 7. TIFF0003250940000002.tif14148The center of the wheelchair 4 is attached by the connecting arm holder 5 on the spring base 2. The connecting arm holder 5 has a hinge at the bottom and can be opened by removing the thumbscrew 6 at the top, and when the connecting arm 4 is attached, it is firmly fastened by the thumbscrew 6. Therefore, the thumbscrew 6 makes it easy to connect and disconnect the bicycle and wheelchair. [Explanation of symbols]

Claims
[Claim 1] The towing connection device is characterized in that a spring 3 is mounted between the flat surfaces of a spring base 1 and a flat surface of a spring base 2 facing each other.
