    Scooter Technical field of the invention The present invention relates to a scooter in accordance with claim 1. The term “scooter” refers here to a vehicle, which is either human-powered or motorized and where a rider stands on a deck between a front wheel and a rear wheel. Background of the invention Scooters, where a rider stands on a deck that is arranged between a front wheel and a rear wheel are becoming increasingly popular. Such scooters have con- — ventionally been human-powered, but the reason for the increased popularity owes mainly to the electrification of the scooters. Scooters that are powered by an electrical motor are an efficient way to travel short distances. A problem with many scooters is that they are not designed for transporting goods. A rider of a scooter can carry a backpack, but for many purposes that is not a practical and convenient way of carrying goods. For example in warehouses there is a need for scooters that are designed for carrying goods. Such scooters could also be used for instance by maintenance people at industrial facilities, or at airports by passengers and the staff of the airport or airlines. Summary of the invention = An object of the present invention is to provide an improved scooter. The char- N acterizing features of the scooter according to the invention are given in claim 1.NN
    O O The scooter according to the invention comprises a frame, a deck for supporting I a user standing on the deck, a front wheel, which is rotatable about a steering & 25 axis for steering the scooter, a rear wheel, a rotatable handlebar, and steering 3 means for transmitting rotational movement of the handlebar to the front wheel
    O O for rotating the front wheel about the steering axis. The steering means comprise > a first rotatable force transmission element that is mechanically connected to the handlebar so that rotation of the handlebar causes corresponding rotation of the first force transmission element, a second rotatable force transmission element that is mechanically connected to the front wheel so that rotation of the second force transmission element causes corresponding rotation of the front wheel about the steering axis, and a third a force transmission element having a shape of a continuous loop and being arranged to transmit rotational movement of the first force transmission element to the second force transmission element.
    With the force transmission elements of the steering means, the handlebar can be moved rearwards. This allows a cargo space to be located between the front wheel and the handlebar. Heavy items can thus be located behind the front wheel, which reduces the risk of tipping over of the scooter.
    According to an embodiment of the invention, the first, second and third force transmission elements are arranged in the vertical direction above the upper surface of the deck. This allows locating the deck lower, which makes the scooter more stable. Also, the first transmission elements are not easily hit by obstacles, which increases safety.
    According to an embodiment of the invention, the first and the second force transmission elements are chain wheels and the third force transmission ele- ment is a chain. Chain wheels and chain form a reliable and precise solution for transmitting the movement of the handlebar to the front wheel.
    Instead of chain wheels and a chain, the first and the second force transmission elements could be pulleys and the third force transmission element could be a belt. The pulleys and the belt could be toothed to avoid slipping of the belt. According to an embodiment of the invention, the first force transmission ele- o ment and the second force transmission element are configured so that rotation D of the first force transmission element over a first rotation angle causes the sec-
    N K 25 ond force transmission element to rotate over a second rotation angle that is 2 within 80—120 percent of the first rotation angle. This makes the steering pre- T dictable. The second rotation angle can be egual to the first rotation angle.
    I a > According to an embodiment of the invention, the first, second and third force 3 transmission elements are arranged within a housing. This protects both the 3 30 force transmission elements and a user of the scooter.O
    N According to an embodiment of the invention, the steering means comprise a steering column for transmitting rotational movement of the handlebar to the first force transmission element and the scooter comprises a cargo space, which is arranged in front of the steering column. Major part of the cargo space can be arranged behind the spinning axis of the front wheel. A cargo space in front of the steering column is easy to load and by placing major part of the cargo space behind the spinning axis of the front wheel, the scooter does not tip over easily. According to an embodiment of the invention, the scooter is motorized. According to an embodiment of the invention, the scooter is two-wheeled. A two- wheeled scooter allows leaning, which makes the scooter more stable when driving into turns or when driving on inclined surfaces.
    — According to an embodiment of the invention, the scooter comprises a pair of front wheels, and the steering means comprise one first transmission element, one second force transmission element and one third force transmission ele- ment for each front wheel. Each front wheel is thus steered by means of an own group of force transmission elements. The arrangement ensures that the steer- ing angles of both front wheels are equal. The first force transmission elements can be integrated into a single part. For instance, in case the first and the second force transmission elements are pulleys, the first force transmission element can be a pulley that is provided with two grooves, each groove receiving a belt. According to an embodiment of the invention, the scooter comprises an electri- cally actuatable kickstand. An electrically actuatable kickstand facilitates parking and pulling out in particular when carrying heavy load.
    According to an embodiment of the invention, the kickstand comprises a shaft, o a support bar that is attached to the shaft and configured to contact the ground O in a parking position of the kickstand, a worm wheel attached to the shaft, a
    N K 25 worm engaged with the worm wheel, and an electric motor coupled to the worm 2 for driving the worm.
    I a a 2 Brief description of the drawings
    LO 2 Embodiments of the invention are described below in more detail with reference N 30 to the accompanying drawings, in which
    Fig. 1 shows a side view of a scooter according to an embodiment of the inven- tion, Fig. 2 shows force transmission elements of the steering system of the scooter of figure 1, Fig. 3 shows force transmission elements of the steering system according to another embodiment of the invention, Fig. 4 shows a front view of a scooter according to an embodiment of the inven- tion, and Fig. 5 shows a kickstand of a scooter.
    Description of embodiments of the invention The present invention relates to a scooter, and in particular a cargo-scooter. The term “scooter” refers here to a light vehicle, which is either human-powered or motorized and comprises a deck, on which a rider can stand. In order to distin- —guish such scooters from motorbike- or moped-type scooters, terms kick scooter, push scooter or stand-up scooter can be used. In the case of electrically powered scooters, terms electric scooter, electrical scooter or e-scooter can be used. The term “cargo-scooter” refers to scooter that is configured to carry cargo. Figure 1 shows a scooter according to an embodiment of the invention. The o scooter comprises a frame 1. The frame 1 extends in the longitudinal direction > of the scooter. The frame 1 can be made of tubular parts, such as steel, alumi- K num or carbon fiber tubes. The frame 1 could also be made of protruded alumi- 2 num profiles or from a composite material. The frame 1 can be made of several parts and different materials can be used in different parts.
    I a > The scooter comprises a front wheel 2 and a rear wheel 3. The rear wheel 3 has 2 a spinning axis 14, about which the rear wheel 3 spins as the scooter moves.
    LO e When the scooter is in an upright position, as shown in figure 1, the spinning N axis 14 is horizontal. As the scooter moves straight forward, the spinning axis 14 is perpendicular to the moving direction of the scooter. The rear wheel 3 is not steerable, i.e. the rear wheel 3 cannot be rotated relative to the frame 1 about any other rotation axis than the spinning axis 14. In the embodiment of figure 1, the rear end of the frame 1 forms a fork, which supports the rear wheel 3. The front wheel 2 has a spinning axis 13. The front wheel 2 can spin about the spinning axis 13. When the scooter is in an upright position, the spinning axis 5 13 is horizontal.
    As the scooter moves straight forward, the spinning axis 13 is perpendicular to the moving direction of the scooter.
    In the embodiment of figure 1, the rear wheel 3 has the same diameter as the front wheel 2. However, in some applications it may be beneficial to provide the scooter with a front wheel 2 having a greater diameter than the rear wheel 3. Each wheel 2, 3 comprises a tire.
    The tires are preferably air-filled tires.
    In the embodiment of figure 1, the scooter is two-wheeled.
    It thus comprises one front wheel 2 and one rear wheel 3. In the longitudinal direction of the scooter, i.e. the driving direction, the front wheel 2 and the rear wheel 3 are arranged along the same line.
    A benefit of a two-wheeled scooter is that it is able to lean. — This makes it more stable when making turns, as the centrifugal forces can be compensated by leaning.
    The ability to lean is beneficial also on inclined sur- faces, as the scooter can be aligned with the vertical direction.
    Figure 4 shows a front view of a leaning scooter.
    The front wheel 2 can be used for steering the scooter.
    The front wheel 2 is rotatable about a steering axis 11. In the embodiment of figure 1, the steering axis 11 is vertical.
    However, the steering axis could also be inclined relative to the vertical direction.
    In the embodiment of figure 1, the steering axis 11 is lo- cated rearwards from the spinning axis 13 of the front wheel 2. The front wheel o 2 is attached to a fork 15. The fork 15 extends from the spinning axis 13 of the 2 25 front wheel 2 above the front wheel 2. The fork 15 is rotatably supported to the N frame 1 by means of bearings 22, 23. = The scooter of figure 1 is a cargo-scooter.
    It is thus configured to carry cargo. z The scooter could be used, for instance, in warehouses for transporting goods, 2 or at industrial facilities for transporting tools and spare parts.
    The scooter could O 30 also be used at airports by passengers or the staff of the airport or airlines.
    The 2 scooter is also suitable for domestic use, for example for transporting groceries N or other goods.
    The scooter comprises a cargo space 12. In the embodiment of figure 1, the cargo space 12 is a basket.
    The basket of figure 1 is made of a wire mesh.
    The cargo space 12 could also be a box.
    The cargo space 12 can be either an open or a closed compartment. The cargo space 12 could thus com- prise a lid or a door for accessing the interior of the cargo space 12. The cargo space 12 could also be a tank for storing a liquid or gas. The cargo space 12 could also be a platform. The scooter could also comprise several cargo spaces. The cargo space 12 could also be configured for transporting pets or children. For instance, the scooter could comprise a child seat. The term cargo-scooter should thus be understood broadly. The scooter could also comprise both a cargo space 12 and a separate child seat. The cargo space 12 could form an integral part of the frame 1. The scooter further comprises a deck 5. The deck 5 is configured to support a rider. The deck 5 forms a platform, on which the rider can stand. The deck 5 is substantially horizontal when the scooter is in an upright position. The deck 5 can be an integral part of the frame 1, or the deck 5 can be a separate part attached to the frame 1. The deck 5 could form the frame 1 of the scooter so that a separate frame is not needed. The deck 5 is arranged between the front wheel 2 and the rear wheel 3. In the embodiment of figure 1, the deck 5 is ar- ranged in the vertical direction below the uppermost points of the wheels 2, 3. This helps keeping the center of gravity of a loaded scooter low, which increases stability when riding the scooter and allows the use of relatively large wheels, which improves the ability to ride over potholes or obstacles. On the other hand, if the deck 5 is located too low, the frame 1 of the scooter can hit the ground when driving over obstacles. The upper surface of the deck 5 is preferably in the vertical direction at a level, which is close to the height of the spinning axis 13, 14 of the wheels 2, 3 from the ground. For instance, the upper surface of the deck 5 can be located at a height that is 40 to 70 percent of the radius of the o wheels 2, 3. In some applications, it may be beneficial that the front wheel 2 has 2 a greater diameter than the rear wheel 3. In those cases, the upper surface of N the deck 5 is preferably in the vertical direction at a level, which is close to the O height of the spinning axis 14 of the rear wheel 3 from the ground. For instance, > 30 the upper surface of the deck 5 can be located at a height that is 40 to 70 percent & of the radius of the rear wheel 3.
    O O The scooter comprises a handlebar 6. In the embodiment of figure 1, the han- 2 dlebar 6 is curved, but the handlebar 6 could also be a straight bar 6. The han- N dlebar could also be for example wheel shaped. The handlebar 6 can be rotated for steering the scooter. The scooter comprises steering means for transmitting rotational movement of the handlebar 6 to the front wheel 2. The steering means comprise a steering column 7. In the embodiment of figure 1, the steering col- umn 7 is vertical when the scooter is in an upright position. The steering column 7 could also be inclined so that the upper end of the steering column 7 is closer to the rear end of the scooter than the front end. The handlebar 6 is attached to the steering column 7 in a rotationally fixed manner. Rotation of the handlebar 6 about an axis that is aligned with the steering column 7 thus causes an equal rotation of the steering column 7. The steering column 7 is supported to the frame by means of bearings 24, 25, 26. A pair of bearings 24, 25 is arranged close to the lower end of the steering column 7. One bearing 26 is arranged close to the handlebar 6. In the embodiment of figure 1, the scooter comprises a support element 27. One end of the support element 27 is attached to the frame 1 of the scooter. The other end of the support element 27 supports the bearing 26 at the upper end of the steering column 7. The bearing 26 at the upper end of the steering column 7 could also be supported by the cargo space
    12. Alternatively, the steering column 7 could be arranged at least partly within arigid tube that is attached rigidly to the frame 1 and the bearing 26 at the upper end of the steering column 7 could be supported by the tube. It is also possible that the steering column 7 is supported solely by two bearings arranged close to the lower end of the steering column 7 or by two bearings, of which one is ar- ranged close to the lower end of the steering column 7 and one is arranged at an upper location.
    The steering means further comprise a first rotatable force transmission element
    8. In the embodiment of figure 1, the first force transmission element 8 is a chain wheel. The first force transmission element 8 is attached to the steering column 7 in a rotationally fixed manner. Rotation of the steering column 7 thus causes o an egual rotation of the first steering element 8. The steering means further com- 2 prise a second rotatable force transmission element 9. In the embodiment of N figure 1, the second force transmission element 9 is a chain wheel. The second O force transmission element 9 is mechanically connected to the front wheel 2 so > 30 that rotation of the second force transmission element 9 causes rotation of the & front wheel 2 about the steering axis 11. In the embodiment of figure 1, the sec- 3 ond force transmission element 9 is connected to the front wheel 2 via the fork LO 15. In the embodiment of figure 1, the first force transmission element 8 is ar- > ranged between the pair of bearings 24, 25 at the lower end of the steering column 7. The second force transmission element 9 is arranged between the pair of bearings 22, 23 supporting the fork 15.
    The steering means further comprise a third loop-shaped force transmission el- ement 10. In the embodiment of figure 1, the third force transmission element 10 is a chain. The third force transmission element 10 transmits rotational move- ment of the first force transmission element 8 to the second force transmission element 9. In the embodiment of figure 1, the first, second and third force trans- mission elements 8, 9, 10 are arranged in a horizontal plane. The chain wheels 8, 9 and the chain 10 of figure 1 are also shown in figure 2. In the embodiment of figure 2, the first chain wheel 8 and the second chain wheel 9 have an equal number of teeth. Rotation of the first chain wheel 8 over a certain angle thus causes an equal rotation of the second chain wheel 9. Consequently, rotation of the handlebar 6 over a certain angle causes a corresponding rotation of the front wheel 2. This makes the steering of the scooter predictable to a rider who is used to riding a typical scooter. Preferably, the first and the second force trans- mission elements 8, 9 are configured so that rotation of the first force transmis- — sion element 8 over a first rotation angle causes the second force transmission element 9 to rotate over a second rotation angle, which is within 80—120 percent of the first rotation angle. If the ratio between the second rotation angle and the first rotation angle is above 1, the steering of the scooter is more responsive, i.e. a smaller rotation of the handlebar 6 causes a greater rotation of the front wheel
    2. On the other hand, with ratios below 1, the steering of the scooter can be made less responsive, which makes the scooter more stable. Instead of using chain wheels as the first and second force transmission ele- ments 8, 9 and a chain as the third force transmission element 10, pulleys can be used as the first and second force transmission elements and a belt as the third force transmission element. The belt could be a toothed belt and the pulleys o could be toothed pulleys. This would effectively prevent slipping of the belt.
    O . The first, second and third force transmission elements 8, 9, 10 allow positioning 2 of the steering column 7 rearwards from the front wheel 2. This allows the cargo T space 12 to extend rearwards from the spinning axis 13 of the front wheel 2. In z 30 the embodiment of figure 1, major part of the cargo space 12 is located rear- 2 wards from the spinning axis 13 of the front wheel 2. The weight of the goods O located in the cargo space 12 is thus behind the front wheel 2. This makes the 2 scooter more stable. In the embodiment of figure 1, the cargo space 12 is located N in front of the steering column 7. The cargo space 12 is thus easy to load and it does not disturb the rider of the scooter. By using chain wheels and a chain or pulleys and a belt as the force transmission elements, the force transmission elements can be easily protected by a suitable housing. This protects the force transmission elements of the scooter from hits by obstacles when riding the scooter and also the user of the scooter is protected from the moving parts of the steering means. As the force transmission elements do not include moving levers, the housing can be small. Figure 4 shows a front view of a housing 28 of the force transmission elements. The chain wheels 8, 9 and the 10 are inside the housing 28 and thus not visible. The width of the housing 28 is only slightly greater than the diameter of the first and second force transmission elements 8,
    9. The force transmission elements 8, 9, 10 allow precise steering of the scooter. They also allow the front wheel 2 to be rotated from a neutral position over 90 degrees to both directions. This is beneficial for instance when riding on narrow corridors. The front wheel 2 can be rotated even a full turn, provided that electric cables and/or brake cables do not limit the movement. The first, second and third force transmission elements 8, 9, 10 are located in — the vertical direction above the level of the deck 5 of the scooter. The force transmission elements 8, 9, 10 are also above the uppermost point of the front wheel 2. By locating the force transmission elements 8, 9, 10 above the upper surface of the deck 5, the deck 5 can be arranged lower and the center of gravity of a loaded scooter can be kept low. The force transmission elements 8, 9, 10 are also not prone to hits by obstacles for instance when riding into turns for instance at narrow corridors of warehouses. In the embodiment of figure 1, the third force transmission element 10 extends in the longitudinal direction of the scooter above the deck 5. The first force transmission element 8 is thus above the deck 5 of the scooter. o 25 The scooter of figure 1 is electrically powered. The scooter comprises a battery > 16, which supplies electric power to a motor. The electric motor (not shown) is K arranged to drive the front wheel 2. The motor can be arranged in the hub of the 2 front wheel 2. In the embodiment of figure 1, the battery 16 is located below the T cargo space 12. However, the battery 16 could also be located differently. For z 30 instance, the battery 16 could be located below the deck 5. The motor could be 2 arranged to drive the rear wheel 3 instead of the front wheel 2.
    O 3 Although a two-wheeled scooter has some benefits, in some applications it may be beneficial to provide a scooter with a pair of front wheels 2. Two front wheels are thus arranged in parallel so that the spinning axes of the front wheels are aligned when the scooter moves straight forward. Figure 3 shows an arrangement of force transmission elements suitable for a scooter with two front wheels. In the arrangement of figure 3, the steering means comprise a pair of first force transmission elements 8. The rotation axes of the first force transmis- sion elements 8 are aligned. The first force transmission elements are attached tothe steering column 7 in a similar way as in the embodiment of figure 1. Figure 3 shows a view from above, and only the upper one of the two first transmission elements 8 (chain wheels) is visible. The steering means further comprise a pair of second force transmission elements 9a, 9b (chain wheels), and a pair of third force transmission elements 10a, 10b (chains). One of the second force trans- — mission elements 9a, 9b is mechanically connected to one of the front wheels 2 and the other of the two second force transmission elements 9a, 9b is mechan- ically connected to the other of the two front wheels 2. One of the third force transmission elements 10a, 10b is arranged between a first pair of the first and second force transmission elements and the other of the two third force trans- — mission elements 10a, 10b is arranged between a second pair of the first and second force transmission elements. The pair of the first force transmission el- ements 8 rotates synchronized, and the two front wheels 2 thus have the same rotation angle with each other. The scooter further comprises a kickstand 17. The kickstand 17 can be moved between an upper position (riding position) and a lower position (parking posi- tion). In the lower position, the kickstand 17 keeps the scooter in an upright po- sition. Figure 5 shows details of the kickstand 17. The kickstand 17 comprises two support bars 18, 19. In the parking position of the kickstand 17, the support bars 18, 19 contact the ground. Each of the support bars 18, 19 has a free end, which is configured to contact the ground in the parking position. Each of the o support bars 18, 19 also has a fixed end, which is attached to the frame 1 of the S scooter. In the embodiment of figure 5, the support bars 18, 19 are L-shaped. N However, the support bars 18, 19 could also have some other shape. For in- O stance, the support bars 18, 19 could be straight. In case of straight support > 30 — bars, the free ends of the support bars could be farther from the longitudinal & center line of the scooter than the fixed ends. The kickstand 17 could also com- 2 prise a single support bar.
    LO 2 The fixed ends of the support bars 18, 19 are attached to the frame 1 of the N scooter via a shaft 20. The shaft 20 is perpendicular to the longitudinal direction of the scooter. A worm wheel 21 is arranged on the shaft 20. The worm wheel 21 isengaged with a worm 22, which is drivable by an electric motor. The electric motor can be used for driving the kickstand 17 from the riding position to the parking position and vice versa. The scooter can be provided with a switch for activating the motor. Alternatively, the scooter can be provided with a sensor detecting a force that has been applied to the support bars for rotating the sup- portbars 18, 19 and the sensor can transmit a signal, which activates the electric motor. The electric motor can thus provide a torque which assists a user of the scooter as the user pushes a support bar 18, 19 for switching the kickstand 17 from a parking position to a riding position or vice versa. The kickstand 17 allows easy parking of a loaded scooter.
    It will be appreciated by a person skilled in the art that the invention is not limited to the embodiments described above, but may vary within the scope of the ap- pended claims.
