Description

  The present invention provides a multi-function bicycle drive mechanism (DIY) device that can be assembled by the user himself. In particular, the holder base having a quick conversion element can be easily assembled into a general frame. Thus, an assembly of a multi-mode mechanism is provided, which has the effect that it can be easily modified.

All current bicycles are already equipped with gearboxes and can provide different travel speed changes, but limited to changing the gear ratio and driving speed, the motion mode has not changed at all. In use, it can only satisfy certain body muscle movements, and the monotonous mode also easily bores the exerciser.
For this reason, the inventor of the present invention has applied for Chinese Patent No. 912268794 “Multifunctional Bicycle Drive Mechanism”. In this device, the movement mode of the bicycle can be changed, and the conventional bicycle continuously rotates. In addition to the drive system, a variety of lever movements, independent movements of individual pedals, etc. can be provided, and such a multi-function drive mechanism can provide a selection of a variety of movement modes. The multifunctional drive mechanism can be further applied to indoor exercise bikes.

However, after actually using the above mechanism, we have found that it has practicality and multi-mode selection, but it has been found that it is easier to use if some structural parts are improved. The structural parts are as follows.
(A) The rear wheel hub must be restricted to use a dedicated improved hub in order to generate the lever motion, and the manufacturing cost of the dedicated hub is relatively high.
(B) The dedicated rear wheel hub is relatively heavy and inconvenient for some users.
(C) With the above mechanism, a failure may rarely occur during use.

  In view of this, the inventor of the present invention carefully researches and observes the points that need further improvement of many defects, and as a result of the research prototype, finally, the actual application 2006-534 “Many” Developed an improved bicycle transmission mechanism with functions. Although the above-mentioned proposal can improve the above-mentioned drawbacks, it is necessary to match a dedicated frame for assembly, and this makes it relatively easy to universalize bicycles suitable for wide use in the market. In addition, it is relatively troublesome to assemble, and cannot be applied to easy (DIY) assembly by itself, resulting in insufficient economic value. Therefore, the inventor of the present plan further developed the present invention “multifunctional bicycle drive mechanism (DIY) device”. Mainly, at the time of assembly of the present invention, it is possible to assemble the whole mechanism into a general frame without using a dedicated frame only by using a rapid conversion element, and this rapid conversion element includes a crankshaft, It has a thread cover and a holder base.

  The original application 2006-534 “Improved transmission mechanism for bicycles with multiple functions”, which was proposed by the present inventor, can achieve a variety of motion mode conversion effects. It is necessary to carry out the assembly by the element and its specialized technical personnel, which is relatively difficult to spread, and special parts, elements, and specialized technical personnel all increase costs, Reduce competitiveness.

  A multi-function bicycle drive mechanism (DIY) device is provided, and a quick change element is mainly attached to a general bicycle, and a multi-mode mechanism can be assembled by a holder base of the quick change element. In this way, a general bicycle frame can have a clutch operation, and the conventional alternating pedal rotation between the cranks, the pedals on both sides are turned up and down simultaneously, the pedals on both sides are turned up and down alternately, one side It can generate the effects of various riding modes such as turning the pedal up and down, rotating, etc., and it is very easy to install, does not require specialized personnel, and can be attached to ordinary bicycles Can achieve practical utility and cost saving, can be more universally used and used in all bicycles.

(Effect of device)
1. With conventional technology, it was impossible to assemble without special parts and elements. However, in the present invention, if there is a fast conversion element, it can be installed by itself, and then the holder of the rapid conversion element. The base can be further used to assemble a multi-mode mechanism, and thus a general bicycle can have various modes of movement, and the installation is very simple and quick. it can.
2. With conventional technology, it was necessary to perform installation work due to specialized technical factors, which increased costs and was not easy to disseminate. The present invention can be completely assembled by oneself and is a very convenient and practical device that is easier to disseminate and more widely accepted.
