Description

[Detailed Description of the Invention] The present invention relates to a foot-operated self-propelled vehicle for games, in which two connected bodies mounted on one elevated rail are self-propelled by the movement of a footboard.

Conventional methods for manually turning a target wheel using foot pedal motion include two methods: rotating a pedal to directly turn the target wheel, as seen on bicycles; There is a method in which the wheels are rotated through a crank due to motion.

On the other hand, in the case of a human-powered self-propelled vehicle for games, especially a self-propelled vehicle that runs manually on a single elevated rail, it is ideal to make it as small as possible, and it is especially desirable that it can be used by everyone from children to adults.

Therefore, when using a bicycle that rotates the pedals like a bicycle, the movement of the knees becomes difficult, and therefore the driver's seat must be made large or uncomfortable.

In addition, a system such as a road vehicle for children in which the pedals are given reciprocating motion and the wheels are rotated via a crank has the disadvantage that the input to the pedals is halved, making the legs tired from exertion.

Additionally, it is necessary to swing the rear end of the vehicle body around the large curves of the elevated rails to maintain smooth running.

Furthermore, when storing a foot-operated self-propelled vehicle, it is necessary to back up the vehicle body, but conventional vehicle bodies do not have a mechanism to lock the rear wheels so that they face straight backwards. The front wheels connected to the mechanism are heavy,
The biggest drawback was that the vehicle could not be backed up smoothly.

As a countermeasure to this problem, it would be ideal if some kind of mechanism could be added that would allow the front wheels to float when backing up.

The present invention aims to provide a self-propelled vehicle on elevated rails devised for the purpose of compensating for each of the drawbacks mentioned above.

An embodiment of the present invention will be described in detail with reference to the drawings.

Figure 1 is a plan view of the right-hand fuselage showing an embodiment of the present invention;
FIG. 2 is a perspective view of essential parts of an embodiment of the foot mechanism of the present invention, and FIG. 3 is a front view of an embodiment of the present invention.

A is the fuselage for the right driver's seat, B is the fuselage for the left driver's seat, and they are connected together with one elevated rail L sandwiched between them.

1 is the left footboard of the right driver's seat, indicating the depressed state, and 1' is the left footplate of the left driver's seat, indicating the depressed state.

Similarly, 2 and 2' are the footboards on the right side of both driver's seats, which are shown floating upward.

3.4, 3', and 4' are supporting arms that are linked to the vertical movement of the stepping boards 1, 2, 1', and 2', and are pivoted in the middle by shafts 5 and 5', respectively. 4 and 3'.

At the other end of 4', there are springs 6, 7, 6' and 7' at the rear, and at the front there is a chain 8 between the support arms 3 and 4, and a chain 8 between the support arms 3' and 4'. are connected.

The chains 8 and 8' are connected to a vertical chain wheel 9
, 10 and 9', 10' and horizontal sprocket wheels 11 and 11' between them.
4, 3', and 4'.

The chains 8 and 8' are connected in the vertical direction at the middle part that meshes with the sprocket wheels 11 and 11', and in the horizontal direction at both ends so that they mesh with the chain wheels 9, 10, γ, and 10'. It is composed of a composite chain with connected chains.

The chain wheels 9, 10 and '! are supported by a shaft 12.1'2' passing under the rail L, and the chain wheels 9, 10 and '! , 10', chain wheels 13, 13' are supported by shafts 12, 12', respectively.

The chain wheels 13 and 13' have chains of 714°1
The shaft 16, which is connected to the upper chain wheels 15 and 15' through the shaft 4' and pivotally supports the chain wheels 15 and 15', has a front wheel 11 that abuts on the rail L in the center. supported.

In addition, aircraft A and B have top plates F c and F c', and seats F.
s.

Fs' consists of an integral frame F consisting of outer frames Ff, Ff', etc., and the front vertical frame Fv.

Vertical guide wheels 18, 19 and 18', 19' for preventing overturning are pivotally attached to Fv', respectively.

Another characteristic of the present invention is that the elevated rail L used in the present invention is composed of upper and lower angles La, La' and vertical plates Lv, Lv' as shown in Fig. 1. Even if the positions of the wheels 1B, 19 and 18', 19' slightly fluctuate up and down, they can clamp the rail L without any problem.

Although some of the above parenthetical symbols are not shown in the drawings, both aircraft A.

B is coordinated to the target.

In addition, in the center front of the frame F that connects the bodies A and B, one end consists of a rear-end collision prevention device 20, the other end a rotatable roller 21, and an auxiliary device 2 pivoted to a pin 22 in the middle.
3 is provided.

The auxiliary device 23 can rotate horizontally or vertically about the bin 22.

The rear collision prevention device 20 has a bumper 24 at its tip and a spring 25 at its rear.

Further, a rear wheel 26 is pivotally attached to the central rear surface of the frame F that connects the bodies A and B, and is capable of rotating and changing direction by contacting the upper surface of the rail L.

A locking tool 28 is provided on the upper part of the rear wheel 26 and includes a butterfly-shaped melon 27 and a groove (not shown) into which the butterfly-shaped melon 2γ is fitted.

A method of operating the foot-operated self-propelled vehicle of the present invention having the configuration of the above embodiment will be described below.

In Fig. 2, when one foot plate 1' of one machine body B is stepped downward, the support arm 3' tilts to the left in Fig. 2, the chain 8' is pulled to the right in Fig. 2, and the chain wheel γ is Rotate to the left in Figure 2.

This chain 8' is then attached to the sprocket wheel 11'
The chain wheel 10' is also attached to the shaft 12' through the chain wheel 10'.
I squirrel at idle.

As shown in Fig. 4, a chain wheel 10', etc. is attached to a shaft 12' with a hexagonal gear a fixed thereto, and a sprocket wheel chain C, which has a built-in pawl that meshes with the chain wheel 10', is attached to the shaft 12'. This is because the rotation is controlled only in one direction since the shaft is attached to the shaft.

At this time, the chain 8' is always stretched by the springs 6' and 7', so that it is not kept slack.

At this time, the other footboard 2' is pulled up because the support arm 4 tilts to the right in FIG. 2, and is returned to the next stepping position.

On the other hand, the shaft 12' rotated to the left in FIG. 2 by the chain wheel holder also rotates the chain wheel 13' fixed to the shaft 12' in the left direction in FIG. In conjunction with the chain wheel 15', the front wheel 17 fixed to the coaxial shaft 16 and in contact with the rail L rotates to the left in FIG. 2, that is, the connected body A.

A self-propelled vehicle consisting of B is moved forward.

In this operation, the other raised footboard 2 is alternately depressed in the same manner as described above, so that the front wheels 17 continue to be driven and the self-propelled vehicle travels on the elevated rail.

At this time, the tread plates 1 and 2 are also depressed alternately in the same way, and the self-propulsion force is increased by the force of the person on board A and B who has the greater tread force, and by the sum of the tread forces of the two people. will be doubled.

The foot-operated self-propelled vehicle of the present invention moves forward on a single elevated rail that has been installed in an endless manner at amusement parks, etc., but it is useful for organizing the self-propelled vehicles when no one is on board and for maintenance. There are times when you want to back up your self-propelled vehicle.

The operation method for backing up the camera will now be described in detail with reference to FIG.

During normal driving, the auxiliary device 2
3 is arranged horizontally, but when backing up the self-propelled vehicle, the collision prevention device 20 is directed upward, the roller 21 is directed downward, and the auxiliary device 23 is placed vertically, as shown by the dashed line in Fig. 3. Rotate it.

At this time, since the rotatable roller 21 is in contact with the rail L, the front wheel 17 is lifted from the rail L, so that the self-propelled vehicle can move freely back and forth.

However, originally, the rear wheels 26 were designed so that even if the rear of the aircraft A and B, which were connected along the curve of the rail L, swung left and right, the bearing shaft was eccentric so that it could change direction. , so when backing up, the direction is not fixed and it is unstable.

Therefore, when backing up, the butterfly-shaped melon 27 at the top of the rear wheel 26 is fitted with a locking tool 28 consisting of a groove (not shown) for fitting the butterfly-shaped melon 27, and the rear wheel 26 is moved backward. It is designed to back up a self-propelled vehicle by fixing it so that it faces straight at the road.

As detailed above, according to the foot-operated self-propelled vehicle according to the present invention,
Since the driving vehicle only moves by moving the foot up and down using a footboard, there is no need for a place to rotate the pedals, and the vehicle can be made smaller.

Also, unlike self-propelled cars for children, there is no need for the effort of reciprocating the legs, and it is effective just by applying the force of stepping against gravity.
