本発明は、従前回転クランクペダルの踏込みを
もつて駆動される自転車、殊に三輪以上の複数の
車輪を有する自転車の駆動操作を前後揺動させる
駆動桿によつてなす駆輪機構の開示に係わる。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention provides a method for controlling the drive operation of a bicycle, which is conventionally driven by depressing a rotating crank pedal, particularly a bicycle having a plurality of wheels of three or more wheels. This invention relates to a drive wheel mechanism that uses a drive rod to drive the wheels.

Previously, this type of drive wheel mechanism had a main drive operation of circular motion by pressing down on a rotary crank pedal, which required a stepping operation that greatly flexed the leg joints and a delicate distribution of force between the legs. .

In some cases, instead of driving the drive wheels, which are normally driven by depressing a rotating crank pedal, a drive rod to which one end of a chain attached to the drive gear of the drive wheels is connected is manually operated. There were some that swayed back and forth.

In the conventional drive mechanism using such a rotating crank pedal, certain physical conditions such as sufficient leg strength and large bending and stretching movements of the legs were required for operation. In the drive mechanism that replaces the operation, a spring is interposed at the free end of a chain connected to the drive rod in order to return the drive rod to its original position, but this is not attached directly to the chain. Because of this, when retracting the drive rod, the elastic force of the spring that pulls the chain is added to the resistance force between the drive gear and the chain, and only arm strength is required. In addition to placing an excessive burden on the driver, the continued retraction operation of the drive rod caused by this method was considered to be a major hindrance to the elderly, children, and physically handicapped people with weak arms.

The drive mechanism according to the present invention has been devised in view of the inconveniences of the conventional drive wheel mechanisms. This is designed to reduce the resistance force associated with operation and reduce the burden of continued rocking operations.

た点に置いた。 In order to achieve these various characteristics, the drive mechanism according to the present invention has a structure in which a drive rod is pivotally erected on a vehicle body frame so as to be able to swing back and forth, and a drive shaft is attached to a drive shaft provided on the vehicle body frame. One end of a chain mounted on a freewheel gear provided on the drive shaft is fixed to the lower part of the drive rod or engaged with a guide gear at the lower part of the drive rod, and the other end of the chain is connected to the vehicle body. The chain was attached to a tension gear that was connected to a frame and elastically supported on the vehicle body frame with a separate spring, and the chain was tensioned so that the lower part of the drive rod was elastically pulled toward the gear. I placed it on the dot.

The driver sits on the vehicle body configured as above,
By pulling the drive rod toward you, the chain attached to the drive gear of the drive wheel is pulled in the direction of driving the wheel, and then by loosening the drive rod, the drive rod is pulled into a spring. It is returned to its original position by the tension gear, which is repulsed by the tension gear, and is ready for the retraction operation.

に働く反力と合力による引伸し力を受ける。 The spring that elastically pulls the tension gear is subjected to a stretching force resulting from the tension of the chain trying to pull it in the direction of the drive rod, a reaction force acting in the direction of the vehicle body frame to which the other end of the chain is connected, and a resultant force.

せた。 The drive rod 1 is pivotally mounted 3 to the vehicle body frame 2 so as to be swingable back and forth, and has a length dimension that allows the driver sitting on the vehicle body, which basically consists of three or more wheels, to grip and swing the drive rod 1. In some cases, the tip of the grip is made to stand upright from the vehicle body frame 2, and in other cases, the tip thereof is used as a grip 1a, and as shown in FIG. A case where a pedal 11a is provided at one end of the drive rod 11 mounted on the shaft 12 is planned separately, and the pedal 11a is provided at one end of the drive rod 11 mounted on the shaft 12. An auxiliary gear 4 is provided on the rod section, and a chain 8 whose one end is connected to the vehicle body frame 2 is attached to the auxiliary gear 4.
and a drive gear 7 mounted on a drive shaft 6 of the wheel 5, and the other end of the chain 8 is connected to the vehicle body frame 2 via a tension gear 9.

Alternatively, a freewheel mechanism may be interposed between the drive gear 7 and the wheels 5 to transmit only one-way motion of the drive rod 1 to the drive gear 7 of the wheels 5, and return motion from the input motion. The drive of the wheels 5, especially the reversing operation of the wheels, was controlled.

I planned to do it.

1, and a pedal 11 is attached to one end of a drive rod 11 that is swingably mounted on a shaft.
a, and a chain 8 is installed between the sprocket that is rotated by a predetermined amount by the stepping action of the drive rod 11 and the drive gear 7 of one wheel 5, and the pulling operation by the chain 8 is performed by the drive rod 11. A freewheel mechanism is provided between the drive gear 7 and the drive shaft 6 or the wheel 5 so that the transmission is transmitted only in the direction in which the driver depresses the wheel. Even physically disabled people can drive smoothly.

設計変更が予定される。 As shown in FIG. 3, if the mounting position of the auxiliary gear 4 provided on the drive rod 1 is located above the pivot joint 3 to the vehicle body frame 2, the drive rod 1 can be pushed in. It is also possible to drive the wheels 5, and it is planned that the design will be changed to suit the driver's preference, as well as a configuration in which the drive rod 1 is retracted.
なお又、チエーン８は補助ギヤ４を介すること

のである。 It is also planned that the chain 8 would be directly attached to the drive rod 1 without using the auxiliary gear 4.

The driving wheel mechanism according to the present invention has the above-mentioned characteristic configuration, and when driving the wheels 5,
By pulling the drive rod 1 toward you by an amount corresponding to its swing width, it is possible to perform a simple and minimum movement, and by adjusting the distribution of the amount of movement of the left and right drive rods 1, it is possible to perform counterclockwise and clockwise movements with the minimum radius of rotation. In particular, the return movement of the drive rod 1 through the chain 8 is achieved by a tension gear which is provided in a so-called pulley-like manner by elastically pulling the spring 10 and tensioning the chain 8. 9, even when the chain 8 is pulled in by a predetermined amount, the amount of stretching and tension are halved compared to when the spring 10 is directly attached to the chain 8, and the spring 10 has more elasticity. Even in the case of using a relatively strong force that does not reduce its attractive force, the burden placed on the retracting operation of the chain 8 could be reduced.
