    专利说明:

    In a first aspect, the invention relates to a method of propelling a transport vehicle.
    According to the method, the carriage comprises two juxtaposed rear wheels and one or more front wheels and a frame between the wheels, the frame also comprising a handle located above and behind the rear wheels.
    This type of transport trolley is used in many places, for example, as wheelchairs and strollers, but in particular also for the transport of golf equipment around the golf course. Here, the user pushes or pulls the carriage around the course, but for disabled or older golfers this can be quite demanding, especially if the course is hilly.
    SUMMARY OF THE INVENTION It is an object of the invention to provide a method that allows both users who are fast and strong to move around with a golf cart or similar vehicle powered by hand, while at the same time giving hardly as strong users a hand-wring to get around with the hand-driven vehicle.
    The method then comprises that the propulsion of the transport carriage is effected by at least one rod, which is connected to the frame of the transport carriage, in the direction of the front wheel of the transport carriage, at the same time as a user has a handle and moves it laterally to determine the direction of progress. The rod, which is linked to the transport trolley, can be driven forward in many ways, for example with the help of another vehicle, but it is essential that the user continues to grip the handle of the transport trolley and move the handle laterally to determine the direction of progress. At the same time, it is important that the rod link allows it to be removed, so that users who do not need help can simply remove the rod.
    In US8662218 B1, an example of such a procedure is shown, but the control is difficult does not happen automatically.
    According to the invention, the rod or rods are pressurized by a motorized carriage with at least one front steering wheel, it being peculiar to the invention that the front steering wheel is actuated via the rod or rod connection for steering after the transport carriage when the user moves the handle of the carriage to one of the sides. Thus, the motorized trolley is a three-wheeled vehicle with front nose wheels, which is directed directly by means of the rod connection to the front conveyor and the user's movements of the handle thereon. Thus, the user still has full control over the direction of transport and can hold on to the handle.
    Conveniently, the front wheel of the motorized trolley is mounted in a fork for rotation about a substantially horizontal axis. At the same time, the wheel is rotatable via an upright bearing around an upright axis and further transmits the rod or rods torque to the fork. Fork-bearing bearing is well known not least from bicycles, and by the rod connection transmitting the torque directly to the fork, a particularly simple and easy construction is achieved.
    The user advantageously sits on the motorized carriage during propulsion and holds on to the handle of the truck, and uses maneuvering pedals to provide control signals for controlling the motorized car's brakes and brakes. Since there is no actual handlebar or other for the user to hold onto the motorized trolley, it is ideal for the user to be able to sit on a seat on the motorized trolley and hold the handle of the transport trolley and at the same time determine the direction of travel as described.
    It is an advantage that two rods transmit compressive force to the frame of the transport trolley in two separate juxtaposed points and receive the pressure from each of their bearing points at each side of the fork. This ensures that even a slight angle between the two vehicles will cause the front fork to turn and thus change the direction of the motorized vehicle so that it follows directly after the transport vehicle. The rods do not have to run in parallel, but may well form a trapezoidal shape along with the bearing axis of the motorized carriage's nose wheel.
    In one embodiment, each rod transmits the compressive force to the frame via a bracket which at a center point is connected to a link member and which embraces a frame member and attaches thereto by a flexible strap which is tensioned between the two end points of the bracket. This construction makes it particularly simple to attach the rods to the frame of a front-mounted transport trolley, and via the linkage and the equally flexible strap it becomes possible to attach the rods to a very wide selection of different transport trolleys.
    The invention also provides a motorized carriage comprising two rear driven wheels as well as at least one front non-driven rotatable steering wheel for determining the direction of propulsion, wherein the steering wheel is mounted in a rotatable fork.
    The special feature of the motorized trolley is that a rod connection from each side of the front fork to a front-mounted truck adds torque to the front fork, the rods being connected to the frame of the transport trolley at separate, juxtaposed points and applying a driving force to the frame of the trolley when the motorized trolley rear wheels are driven. With this motorized trolley it is possible to alleviate the problems that, for example, golfers may have in transporting trolleys around a golf course.
    It is preferred that the motorized trolley comprises a seat and two maneuvering pedals, the length of the rods being adjusted after a user sitting on the seat has a handle belonging to the proposed transport trolley within reach. This makes it both comfortable and safe for the user to use the motorized trolley, because he can easily control both the direction of travel and speed and braking, and he can also, by holding on to the handle, feel protected against the risk of falling off the motorized trolley.
    According to the invention, there is also provided a releasable link between a motor-driven carriage with a rod connection and the front-mounted transport vehicle as stated above.
    In particular, the detachable connecting link is comprised of an un-shaped hanger with hooks at the end of each of the u-legs and an elastic strap with one or more attachment points adapted to engage the hooks so that the un-shaped hanger can be attached to a frame member of the proposed transport vehicle, and that the connecting link also comprises a swivel between the un-shaped hanger and a rod connection.
    The strap and swivel joint ensure that the detachable connecting link is particularly flexible and can be attached to many different types of frame parts and yet easily and securely attached to it.
    It is convenient if further the un-shaped hanger can be rotated freely 360 degrees around its bearing axis, because it can always be turned correctly in relation to a given frame element.
    The invention will now be explained in more detail with reference to the drawings, in which:
    FIG. 1 shows a detachable linkage together with a rod,
    FIG. 2 shows the linkage with indication of the movement of the swivel joint
    FIG. 3 shows the rotatability of the joint,
    FIG. 4, the linkage is in a position corresponding to that of a frame member,
    FIG. 5 illustrates the design of the strap,
    FIG. 6 is the top view of the motor carriage,
    FIG. 7 is the carriage of FIG. 6 seen from the side,
    FIG. 8 is a front view of the carriage,
    FIG. 9 shows a golf cart transport vehicle, and
    FIG. 10 is another well-known golf equipment carrier.
    In FIG. 1 and FIG. 5 shows an un-shaped hanger 1 which forms part of a detachable connecting link 10. In FIG. 7 shows a motorized carriage 7 with a rod connection 4 which is connected to a detachable connecting link 10, and a front-mounted transport carriage 8 is shown in FIG. 9 and FIG. 10. The un-shaped hanger 1 of the connector has hooks 25 at end points 24 of each of the U's legs. As seen in FIG. 1, the hook 25 is, on the one hand, slightly wider to form a more permanent connection with an elastic strap 5. The strap 5 has one or more fastening locations 11 arranged for engagement with the hooks 25 as shown in FIG. 2. The fastening points 11 are designed as square punches or openings in the strap, but they can be made in many other ways.
    The un-shaped hanger 1 can be attached to a frame 20 by a front-mounted transport trolley 8. This is done by inserting a part of a frame 20 between the two legs of the un-shaped hanger, and then clamp the strap 5 to tighten up behind about the frame part as shown in FIG. 4th
    As seen in FIG. 1, the detachable connecting link 10 also includes a swivel joint 3. The swivel joint 3 sits between the un-shaped hanger 1 and a rod joint 4. The swivel joint 3 can, as indicated in FIG. 2, turn 100 degrees to each side. At the same time, there is full rotatability of the un-shaped hanger 1 around a bearing axis on a short rod 2, as indicated in FIG. 3. It is thereby achieved that it will always be possible to get hold of a frame part of the proposed transport truck 8 almost no matter how it is constructed.
    As seen in FIG. 2, 4 and 5, the non-molded bracket on the inside is coated with an elastic coating 6, so that, when connected with points 9 of the frame 20, it does not cause scratches or other marks.
    Figures 6, 7 and 8 show a motor-driven carriage 7 comprising two rear driven wheels 12. The driven wheels 12 are driven, for example, by an electric motor or by an internal combustion engine, as is well known for small wagons for transporting a single person. At the front there is a non-driven, rotatable steering wheel 13. The steering wheel 13 can be turned and thus determine the direction of travel, this wheel being mounted in a rotatable fork 14 as is well known for the type of wagons.
    Usually, the person transported on the carriage can turn the fork 14 via a suitable guide, but this can be omitted by this carriage. Instead of a guide, a rod connection 4 has been established from each side of the front fork 14 to a front-mounted transport truck 8. The rod connection 4 now supplies torque to the front fork 14, the two rods in the rod connection 4 being connected to the frame 20 of the transport truck in separate, juxtaposed points 9. Side points here mean that the points sit symmetrically in relation to the rear pair of wheels, so that the points are both raised the same distance over the joint axis of rotation of the wheels, and sit on either side, but equally far from a plane of symmetry in the middle between the juxtaposed rear. wheel 18. When the angle between the two vehicles changes, the steering wheel 13 will rotate accordingly. At the same time, the frame 20 of the transport trolley exerts a driving force when the rear wheel 12 of the motorized trolley is driven.
    As seen in FIG. 9 and 10, the carriage 8 has two juxtaposed rear wheels 18 and one or more front wheels 19 and a frame 20 connecting the wheels 18, 19. The frame 20 will be arranged to carry a load, and in the examples shown, the load comprises sports props such as golf playing equipment. The load is not shown in the figures. The frame can, as seen in FIG. 9 and FIG. 10, a part of the structure varies from one carriage to the other, and the juxtaposed points 9 to which the un-shaped shackles are to be attached are then differently positioned. In the example of FIG. 8, the points are located on two parallel running parts under the handle 17, and on the carriage of FIG. 10, the points are seated on two inclined wheel bearing frame parts. However, due to the rotatability and rotatability of the un-shaped hanger 1 relative to the rod 4, this is not a problem.
    The frame 20 here also includes a handle 17 which is located above and behind the rear wheels 18. Golfers usually grip the handle 17 to pull or push the carriage across the course. For the elderly and / or disabled, this can be physically demanding, especially when the course is laid on hilly terrain.
    According to the embodiment of the invention, the propulsion is effected by at least the rod 4, which is connected to the frame 20 of the carriage 20, being pressurized in the direction of the front wheel 19 of the carriage at the same time as a user has the handle 17 and moves it laterally to determine the direction of progress. The rod or rods 4 can be pressurized in various ways, but most conveniently this is done by a connection with the motor carriage 7.
    The motorized trolley 7 thus becomes an independent unit which is put behind the transport trolley 8 as needed and can be easily detached from the transport trolley by simply releasing the un-shaped hanger (s) 1 from their connection with the parallel points 9 on the frame 20.
    As shown in FIG. 8, the rods are connected to either side of the front fork 14, for example directly to a through shaft 22 at bearing points 23 provided here. Hereby, the rods will be actuated for control of the transport carriage as the user moves the handle 17 of the carriage to one of the sides. As also shown in FIG. 8, the steering wheel 13 of the motor vehicle is mounted in the fork 14 and a shaft 22 through the two branches of the fork allows rotation about a substantially horizontal axis through the shaft 22. At the same time, the fork 14 is rotatable about an upright axis 21. This construction ensures that the rods 4 transmits torque to the front fork 14 as soon as there is an angle between the carriage 8 and the motor carriage 7.
    As seen in FIG. 8, the motorized trolley 7 is equipped with a seat 15 so that the user can sit down during the propulsion. At the same time, the user holds on to the handle 17 of the truck and uses maneuver pedals 16 to provide control signals for controlling the motor and brakes of the motorized trolley.
