Abstract

PROBLEM TO BE SOLVED: To achieve a pusher type movable carriage such as a rear car, which was attracted by a cycle or a motorcycle for general purpose use, the pusher type movable carriage is configured so that a passenger compartment is not inclined even when a rear deck is at a slope or the like.SOLUTION: A two-wheel carriage is rotated and supported in a slidable state on a turn table. The two-wheel carriage and a cycle or a motorcycle which is a drive vehicle are detachably coupled by using a coupling tool provided on the turn table. The drive vehicle may be partially remodeled or general commercial vehicle. On a rear deck, a passenger compartment for passenger is mounted for using as a cycle taxi.

Description

  The present invention relates to a two-wheel pusher type moving carriage, which is propelled in combination with a bicycle or a motorcycle.

With courier services in full swing, trolleys and rear cars are used in alleys that cannot be used by four-wheeled vehicles. A general cart is a four-wheel push-up type and a rear car is a two-wheel pull type, but its mobility is poor and it is difficult to move over a long distance.

Rear cars that are towed by bicycles and motorcycles are also used, but it is difficult to change direction in narrow alleys due to poor turning performance, and there is also a high possibility of loss due to the loading of luggage. Also, on the slope, the cargo bed tilts, so there was a possibility that the luggage would fall

In a bicycle taxi that pulls people on board, the passengers are located behind, so the front view cannot be seen. In addition, there was a drawback that fear caused by the inclination.

A pusher-type mobile trolley that is easy to connect with propulsion vehicles such as bicycles and motorcycles, has good mobility, and can move safely even on hills, and eliminates the above-mentioned drawbacks. It is.

Wheels are provided on both ends of the loading platform, and the lower surface of a two-wheeled carriage having a handle is rotatably supported by a turntable via a bearing or the like. This turntable is provided with a coupler for coupling with a body frame of a bicycle or motorcycle.

This two-wheeled carriage is moved forward by the propulsion power of the combined bicycle and motorcycle. As a result, the driver can drive while looking at the luggage loaded on the carrier, and can safely drive without worrying about loss.

If you use a partially modified bicycle or motorcycle, you can operate it more efficiently, but you can combine a commercial vehicle that is not modified.

The propulsive force is transmitted to the turntable, and the loading platform is slidably supported on this upper surface. Smooth turning is possible while driving. Because it is a pusher type, the field of view in the direction of travel is widened and looks good, so you can drive safely. And since there are three ground wheels, it has good mobility and is suitable for narrow alleys.

Further, since the coupler is refractable, the bending angle can be actively controlled by a servo mechanism or the like on the slope as shown in FIG. 3 to keep the level.
As shown in Fig. 8, if passenger seats are mounted on the loading platform and used as a bicycle taxi, passengers can see the front and enjoy the scenery without feeling afraid because they can keep the boarding position even on hills. . Further, if a cart dedicated to two-seater infants as shown in FIG. 9 is combined with a bicycle, a two-seater infant traveling safely and lightly becomes possible.

Hereinafter, an embodiment of the present invention in which the bicycle coupler 250 can be expanded and contracted will be described.
As shown in FIGS. 1 and 2, the lower surface of the carriage 100 is joined to the turntable 200 via the thrust type bearing 130 and slides with the rotation support shaft S as the rotation axis. Can be converted.

The turntable 200 has a bicycle coupling tool 250 that is extendable and refractable. A bicycle body frame is coupled to the turntable 200, and the carriage 100 is advanced by the driving force of the rear wheel of the bicycle.

Depending on the size of the luggage, the bicycle coupler 250 can be freely expanded and contracted, so that the entire balance including the bicycle and motorcycle as the propulsion vehicle can be adjusted and operated.

In addition, the bicycle coupler 250 is provided with an active refractive coupler 258 that can be bent, and the angle of the active coupler 258 is actively changed by a built-in servo mechanism or the like, so that the bed surface can be moved on the slope as shown in FIG. Since it can be kept horizontal, for example, when a person is placed on the platform, there is no fear of fear due to the inclination.

FIG. 4 shows an example in which unicycles are combined. A coupling rod 450 protruding from the frame of the unicycle bicycle 400 is coupled to the bicycle coupling tool 250 of the two-wheeled carriage 200 and operated with the handle 180. As shown in the drawing, the best bicycle-driven two-wheel carriage is realized by combining the single-wheel bicycle 400 specialized for the present invention.

FIG. 5 shows an example in which a modified bicycle 500 to which a part of a body frame of a commercial bicycle is cut and a coupling rod 550 is attached is coupled. Since the three wheels of the rear wheel of the modified bicycle 500 and the two wheels 150 of the carriage 100 are grounded and run, the mobility is improved.

FIG. 6 shows an example in which a bicycle 600 having only a front fork 650 is joined by removing the front wheel and handle of a commercially available bicycle. After eliminating the connection with the present invention, it can be reused as a normal commercial bicycle by attaching the front wheel and the handle.

FIG. 7 shows an example in which an unmodified commercial bicycle 700 is coupled as it is. If the front wheel of the commercially available bicycle 700 is placed on the front wheel mounting tool 270 of the turntable 200 and fixed to the bicycle body frame, the front wheel floats in the air and only the rear wheel contacts the ground. Thereby, the three wheels of the rear wheel of the commercially available bicycle 700 and the two wheels 150 of the carriage 100 are grounded. When it is desired to cancel the connection with the present invention, the commercially available bicycle 700 can be used as it is by removing it from the front wheel mounting tool 270.

FIG. 8 shows an example in which a passenger cabin 800 on which a passenger is placed on a cart 100 is mounted. You can see the scenery well and the feeling of fear is not felt because the loading platform remains level even on the slope.

FIG. 9 shows an example in which the carriage is a two-seater carriage 190 for infants. Specializing in the seat where two infants can ride the cart, by making the wheel 150 as small as possible, it is possible to place two infants at a position with a low center of gravity, so it is difficult for the infants to fall and the infants also progress The direction is clearly visible, and it is possible to drive safely.
