Description

{A bicycle with four-wheel drive system for closure railroad}

The present invention relates to a four-wheeled bicycle device for closed tracks.

Recently, two-wheeled or four-wheeled vehicles have been proposed as a riding bicycle device using a rolling moon or a power means as a means of transportation using a closed track by local governments.

Most of the trolleys applied to the above-mentioned bicycles that run in a closed / closed way using a straight closed track, most of the means such as bicycles to run in one direction only on a straight line rather than a reverse driving function.

Because of this, except for the circular continuous line, in order to drive in one direction on the closed straight rail, and then to reverse run, it was inconvenient to lift the track bicycle and place it on the rail in the opposite direction.

In continuous tracks or on-the-road driving, only the steering wheel of the front wheel can be driven by the omnidirectional driving device as described above. However, the reciprocating driving device as described above has not been proposed in a closed straight line of a certain section.

In view of the above, the present invention proposes a four-wheeled bicycle device for a closed track, which allows not only a closed track in a straight line but also a forward and backward running on a continuous track.

To this end, the object of using the four-wheeled bicycle for the closed line as described above should be easy to operate the driving forward and backward mostly by female drivers with children.

In addition, since the front and rear positions of the saddle according to the forward and backward movement is running backwards, a simple operation for this should also be proposed.

In addition, it is a four-wheeled bicycle running at the same time in a short closed section, because the impact impact due to the heavy body should be provided with a safe and durable safe brake operating device.

Assemble (605) and stop inside diameter at both ends of ratchet closing gear box (604) Ring is fixed (604 ') to post-assembly, by assembling the pyedal 611 to either side of putting the bit ratchet gear cover 601 is then assembled with the ratchet gear cover tree assembly bolt 602. Stopper plate 612.

Figure 4 is an excerpt perspective view of the brake lever portion installed in the wheel portion according to the present invention, the outer ring portion of the spoke-shaped rim 201 one end surface of the ' b ' type reinforcement and fixed to the stepped end jaw rim 202 A wire assembled to the hinge shaft of the brake lever part 500 hinged to the middle of the longitudinal chassis 100 at both ends of the brake plate 403 flanged to the intermediate shaft of the drive shaft 404, the wheel portion 200 is assembled ( The brake plate clamp fixing shaft 408 is fixed below the luggage compartment seat 100C so that the brake plate clamp 402 combined with the 401 is installed close to each other.

On the other hand, the chain 408 is installed between the chain gear of the ratchet closing gear 602 of the ratchet closing gear unit 600 and the drive shaft gear 405 fixed to both sides of the driving shaft 404.

The present invention configured as described above is one embodiment.

The driver who rides on the saddle portion 300 of the four-wheeled bicycle device for a closed track according to the present invention is a person who runs on the pedal moon of the ratchet lung gear 600, and a passenger rides on the auxiliary fixed saddle 300A.

First, when a maximum of two passengers simultaneously ride the ratchet lever 603 in the direction to proceed by holding the bicycle-type handle 400A, the ratchet pedal gear 602 as shown in the reference figure 3. The ratchet lever cam 603a installed at the upper center of the ratchet gear 609 in the ratchet gear box 607 formed in the inner ring portion and the direction selecting levers b and 610a and 610b installed to the left and right. 610a is spaced apart from the ratchet gear 609, the direction selection lever a (610a) is transmitted to the rotational force of the closing moon 611 in a gear-coupling state with the ratchet gear 609 through the chain 613, As shown in FIG. 4, the drive shaft gear 405 is driven to drive the track by the rotation of the wheel part 200.

In this way, in order to drive back in one direction on the closed straight track rail and then to reverse travel, if the driver operates the direction of the saddle 300 in the opposite direction and then operates the ratchet lever 603 in the opposite direction, the reference figure 3 is shown in Reference Drawing 3 As described above, the ratchet lever cam 603a installed in the upper center of the ratchet gear 609 in the ratchet gear box 607 formed in the ratchet closing gear 602 and the inner ring portion thereof, and the direction selection lever a installed on the left and right sides thereof, Among the b (610a and 610b), the direction selection lever a (610a) is spaced apart from the ratchet gear 609, and the direction selection lever b (610b) is in close contact with the ratchet gear 609 in a closed position (611). The rotational force is transmitted through the chain 613, as shown in FIG. 4, to drive the drive shaft gear 405 so as to reversely travel the track by the rotation of the wheel part 200.

In the above, the operation of changing the direction of the saddle 300 of the driver, as shown in Figure 2 of the reference drawing, the driver lifts the saddle upwards, the clamp 306 fixed below the saddle shaft 303 Is spaced apart from the longitudinal chassis 100, the journal fixed to the end of the saddle neck portion 304 fixed by the sieve stopper 302 axially assembled on the saddle rotary shaft pipe 301 fixed on the longitudinal chassis 100 The saddle shaft 303 is raised and lowered by the vertical gap formed in the 305 to separate the clamp 306 from the longitudinal chassis 100 so that the front and rear directions of the saddle can be easily changed.

The straight handle 400B of the apparatus implemented as described above serves as a handle of a driver to be mounted when the saddle is changed in direction.

In addition, the shock-absorbing rubber (100E; 100E ') settled in the front and rear of the luggage compartment chassis (100A) or the auxiliary seat seat chassis (100B) impacts when the vehicle collides with another vehicle that is driving or when it hits the stop wall by not holding the brake. Play a role in mitigating.

In addition, the stepped outer jaw outer rim 202 having one end of the outer ring portion of the spoke-shaped rim 201 of the wheel portion 200, which is ' b ' type, is reinforced to reduce the weight of the truck. Only the press-formed rims 201 adopted and the stepped rims mounted on the track are completed to be reinforced and assembled on the rims 201 after casting molding for stable running and prevention of departure.

The four-wheel bicycle device for a closed line according to the present invention configured as described above saddle shaft 303 is attached to the saddle neck 306 and the saddle shaft 305 formed up and down clearance gap formed in the saddle rotary shaft pipe 301 The saddle 300 is easily replaced in the front and rear by the clamp 306 mounted on the longitudinal chassis 100, and the drive shaft is provided by the ratchet lever 603 introduced into the ratchet closing gear 600. It is possible to arbitrarily manipulate the direction of power transmitted to the gear 405, and it is a four-wheeled bicycle device for closed tracks that enables forward and backward driving as well as closed tracks in a straight line. It is intended to simplify the operation.

In addition, the brake formed by a large disk on the drive shaft 404 by mounting the brake lever unit 500 on the longitudinal chassis 100 with a safe brake operation device that is safer and more durable because the impact impact caused by the weight is large. The brake plate clamp 402 for clamping the plate 403 is designed to be useful as a device in which the braking document is improved by operating the wire 401.
