СКЛАДНОЙ ВЕЛОСИПЕД-ТЕЛЕЖКА Область техники FOLDING BIKE TROLLEY
Заявляемое изобретение относится к транспортным средствам для перевозки людей, а более конкретно, к трехколесным складным велосипедам, преобразуемым в другие транспортные средства, например, в транспортную тележку, перемещаемую вручную по дороге.The claimed invention relates to vehicles for transporting people, and more particularly to tricycles folding to other vehicles, for example, to a transport trolley that is manually moved along the road.
Предшествующий уровень техникиState of the art
Известно много конструкций складных велосипедов и велосипедов с багажниками. Например, тележка с педальным механизмом: для универсамов (см. заявка FR Na 2606357, МПК B62K 7/00, 1986). Эта тележка громоздка и не может складываться.Many designs of folding bicycles and luggage racks are known. For example, a trolley with a pedal mechanism: for supermarkets (see application FR Na 2606357, IPC B62K 7/00, 1986). This trolley is bulky and cannot fold.
.Известен велосипед со складной рамой (см. заявка PCT Ns 88/01961.. A bicycle with a folding frame is known (see PCT application Ns 88/01961.
МПК B62K 15/00, 1989), в конструкции которого использован один (или несколько) простой зажим. Этот велосипед может быть сложен в течение несколько секунд в компактный узел, но он не имеет багажника и не предназначен для перевозки грузов.IPC B62K 15/00, 1989), in the construction of which one (or several) simple clamps are used. This bike can be folded into a compact unit for a few seconds, but it does not have a boot and is not designed to carry goods.
Известен также складной двухколесный велосипед (см. заявка PCT Ns 87/01084, МПК B62K 15/00, 1987), который в сложенном состоянии служит тележкой. Он складывается в точке сгиба, расположенной посредине рамы, так, что переднее и заднее колеса соединяются между собой, и велосипед превращается в тележку. Но в этом случае багажник образуется только при сложении. На таком велосипеде невозможно перевозить груз.Also known is a folding two-wheeled bicycle (see PCT application Ns 87/01084, IPC B62K 15/00, 1987), which when folded serves as a trolley. It develops at the bend point located in the middle of the frame, so that the front and rear wheels are connected to each other, and the bike turns into a trolley. But in this case, the trunk is formed only when added. It is not possible to carry cargo on such a bicycle.
Известно также одноколейное транспортное средство (см. Авторское свидетельство SU Ns 1104046, МПК B62K15/00, 1982). Велосипед содержит раму из двух шарнирно сочлененных частей. Первая часть рамы выполнена в виде жесткого треугольника, в одной из вершин которого смонтировано заднее колесо, в другой - кареточный узел, а в третьей вершине установлены фиксатор, седло и шарнир для соединения со второй частью рамы. Вторая часть рамы соединена с рулевым стержнем и рулем. Шарнирами также соединены руль и подседельный элемент. Велосипед имеет две степени сложения. Первая удобна для движения по дороге, а вторая - для хранения.A single track vehicle is also known (see Copyright Certificate SU Ns 1104046, IPC B62K15 / 00, 1982). The bicycle contains a frame of two articulated parts. The first part of the frame is made in the form of a rigid triangle, at one of the vertices of which the rear wheel is mounted, the carriage assembly at the other, and the retainer, saddle and hinge for connecting to the second part of the frame are installed at the third vertex. The second part of the frame is connected to the steering shaft and the steering wheel. The steering wheel and seatpost are also connected by hinges. A bicycle has two degrees of folding. The first is convenient for driving on the road, and the second is for storage.
Недостатками известного велосипеда являются сложность конструкции - большое количество шарнирных соединений и фиксаторов, отсутствие багажника, что исключает использование велосипеда в сложенном состоянии в качестве тележки.The disadvantages of the known bike are the complexity of the design - a large number of articulated joints and clips, lack of a trunk, which excludes the use of the bicycle when folded as a trolley.

Moreover, the wheel rotation drive is made on the steering rod in the form of a pedal drive. The cylindrical articulated elements are biased towards ιо from the front wheel to the rear wheels. On the front link of the frame is a saddle for the driver.

Раскрытие изобретенияDisclosure of invention
Задачей настоящего технического решения является разработка такого складного велосипеда-тележки, который бы имел лучшую управляемость и имел повышенную компактность при его сложении в положении тележки. зо Поставленная задача решается тем, что складной велосипед-тележка содержит раму, выполненную, по меньшей мере, из двух звеньев, сочлененных с помощью цилиндрических шарнирных элементов. Первое звено имеет рулевую колонку, в которой установлен рулевой стержень с рулем и передним рулевым колесом. На втором звене установлены два задних колеса,The objective of this technical solution is to develop such a folding bicycle trolley, which would have better handling and have increased compactness when it is folded in the position of the trolley. The task is solved in that the folding bicycle trolley contains a frame made of at least two links articulated with cylindrical hinge elements. The first link has a steering column in which a steering rod with a steering wheel and a front steering wheel is installed. The second link has two rear wheels,
35 разнесенных в поперечном направлении относительно оси рулевой колонки. Также велосипед снабжен приводом вращения колес. Причем привод вращения колес размещен на втором звене рамы и кинематические связан с задними колесами. Цилиндрические шарнирные элементы смещены в направлении от задних колес к переднему колесу. Звенья рамы выполнены дугообразными, спрямленными и сонаправленными к концам, а также соответствующими друг другу по форме и размерам.35 spaced in the transverse direction relative to the axis of the steering column. The bike is also equipped with a wheel rotation drive. Moreover, the rotation drive wheels placed on the second link of the frame and kinematic connected to the rear wheels. The cylindrical hinge elements are offset in the direction from the rear wheels to the front wheel. The links of the frame are made arcuate, straightened and codirectional to the ends, as well as corresponding to each other in shape and size.
Перенос привода вращения колес с рулевого стержня (что имеет место в прототипе) на второе звено рамы позволило освободить водителя от необходимости согласовывать работу рук и ног в зависимости от направления движения, и за этот счет улучшить управляемость заявляемого велосипеда- тележки.The transfer of the wheel rotation drive from the steering rod (which takes place in the prototype) to the second link of the frame freed the driver from the need to coordinate the work of the arms and legs depending on the direction of movement, and thereby improve the controllability of the inventive bicycle trolley.
Кроме того, перенос привода вращения от рулевого стержня на второе звено позволило изменить форму звеньев рамы и сделать их предельно совмещаемыми друг с другом (без зазоров), т.е. выполнить их дугообразными, спрямленными и сонаправленными к концам, а также соответствующими друг другу по форме и размерам, что позволяет заявляемому велосипеду-тележке в собранном виде, т.е. в положении тележки занимать минимальное место в городском транспорте и на многолюдных улицах города, чем и достигается поставленная техническая задача: уменьшения габаритов тележки и улучшение управляемости велосипеда. Звенья рамы могут быть выполнены П-образной формы, что является одной из возможных (технологичных и простых) форм выполнения звеньев рамы.In addition, the transfer of the rotation drive from the steering rod to the second link made it possible to change the shape of the frame links and make them extremely compatible with each other (without gaps), i.e. to make them arcuate, straightened and codirectional to the ends, as well as corresponding to each other in shape and size, which allows the claimed bike trolley in assembled form, i.e. in the position of the trolley occupy a minimum place in public transport and on the crowded streets of the city, which achieves the technical task: reducing the dimensions of the trolley and improving the handling of the bike. The links of the frame can be made U-shaped, which is one of the possible (technological and simple) forms of execution of the links of the frame.
Рама может быть выполнена из двух сочлененных звеньев, цилиндрические шарниры которых, в свою очередь, выполнены с возможностью ограниченного перемещения вдоль спрямленных сонаправленных концов звеньев, что является одним из возможных вариантов сложения велосипеда в тележку.The frame can be made of two articulated links, the cylindrical joints of which, in turn, are made with the possibility of limited movement along the straightened codirectional ends of the links, which is one of the possible options for folding the bike into a trolley.
Рама также может быть выполнена из трех сочлененных звеньев, причем третье звено установлено между первым и вторым звеньями, что является другим вариантом сложения велосипеда в тележку.The frame can also be made of three articulated links, and the third link is installed between the first and second links, which is another option for folding the bike into a trolley.
Рулевой стержень может быть выполнен с возможностью продольного перемещения относительно рулевой колонки, снабжен фиксаторами верхнего и нижнего положений, что позволяет осуществлять более компактное сложения велосипеда в тележку. Привод вращения колес может быть выполнен в виде двух оппозитно расположенных педалей, кинематически связанных с ведомой осью, на которой установлены два задних колеса, что является одним из возможных вариантов выполнения привода вращения задних колес велосипеда-тележки.The steering shaft can be made with the possibility of longitudinal movement relative to the steering column, equipped with clamps of the upper and lower positions, which allows for more compact folding of the bicycle into the trolley. The wheel rotation drive can be made in the form of two opposed pedals located kinematically connected with the driven axis, on which two rear wheels are installed, which is one of the possible versions of the drive rotation of the rear wheels of the bicycle trolley.
Привод вращения задних колес может быть выполнен в виде двух оппозитно расположенных рычагов, кинематически связанных с ведомой осью, на которой установлены два задних колеса, что является другим вариантом выполнения привода вращения задних колес велосипеда.The drive of rotation of the rear wheels can be made in the form of two opposed levers, kinematically connected with the driven axis on which two rear wheels are mounted, which is another embodiment of the drive of rotation of the rear wheels of a bicycle.
Привод вращения задних колес может быть выполнен в виде электрического двигателя, вал которого кинематический связан с задними колесами, а блок электропитания двигателя в виде аккумулятора размещен на переднем звене рамы, что является еще одним вариантом выполнения привода вращения задних колес велосипеда.The drive of rotation of the rear wheels can be made in the form of an electric motor, the kinematic shaft of which is connected to the rear wheels, and the power supply unit of the engine in the form of a battery is located on the front link of the frame, which is another embodiment of the drive of rotation of the rear wheels of a bicycle.

Варианты осуществления изобретенияEmbodiments of the invention
Заявляемый складной велосипед-тележка может быть выполнен в варианте одинарного или двойного сложения звеньев рамы. Сначала рассмотрим вариант одинарного сложения велосипеда в тележку (фиг. 1 , фиг. 3, фиг. 4). Складной велосипед-тележка содержит раму 1 , выполненную из двух, сочлененных с помощью цилиндрических шарнирных элементов 2, звеньев: первого звена 3 и второго звена 4. Первое звено 3 имеет рулевую колонку 5, в которой установлен рулевой стержень 6 с рулем 7 и передним рулевым колесом 8. На втором звене 4 установлены два задних колеса 9, разнесенных в поперечном направлении относительно оси рулевой колонки 5. Также велосипед снабжен приводом 10 вращения задних колес 9, размещенный на втором звене 4 рамы 1 и кинематически связанный с задними колесами 9. Цилиндрические шарнирные элементы 2 смещены в направлении от задних колес 9 к переднему колесу 8. Звенья 3, 4 рамы 1 выполнены П-образной формы. Цилиндрические шарнирные элементы 2 выполнены с возможностью ограниченного перемещения вдоль спрямленных сонаправленных концов первого звена 3, что позволяет осуществлять сложение звеньев 3 и 4. В конструкции предусмотрены фиксаторы (на чертежах не показаны) в двух положениях заявляемого устройства: в положении разложенного велосипеда и в сложенном положении тележки.The inventive folding bike trolley can be made in single or double addition of frame links. First, consider a single folding bike into a trolley (Fig. 1, Fig. 3, Fig. 4). Folding bicycle trolley contains a frame 1 made of two articulated by means of cylindrical hinge elements 2, links: the first link 3 and the second link 4. The first link 3 has a steering column 5 in which a steering shaft 6 with a steering wheel 7 and a front steering wheel is mounted wheel 8. On the second link 4 there are two rear wheels 9, spaced in the transverse direction relative to the axis of the steering column 5. The bicycle is also equipped with a drive 10 for rotating the rear wheels 9, located on the second link 4 of the frame 1 and kinematically connected with the rear wheels 9. The cylindrical hinge elements 2 are displaced in the direction from the rear wheels 9 to the front wheel 8. The links 3, 4 of the frame 1 are made in a U-shape. The cylindrical hinge elements 2 are made with the possibility of limited movement along the straightened codirectional ends of the first link 3, which allows the addition of links 3 and 4. The design provides latches (not shown) in two positions of the claimed device: in the unfolded position of the bicycle and in the folded position carts.
Теперь рассмотрим вариант двойного сложения велосипеда в тележку (фиг. 2), при котором велосипед содержит раму 1, выполненную из трех сочлененных звеньев, причем третье промежуточное звено 11 установлено между первым звеном 3 и вторым звеном 4. Причем, с первым звеном 3 промежуточное звено 11 связано цилиндрическим шарнирным элементом 2, а со вторым звеном 4 промежуточное звено 11 связано цилиндрическим шарнирным элементом 12. Рулевой стержень 6 выполнен с возможностью продольного перемещения относительно рулевой колонки 5 и снабжен фиксаторами верхнего и нижнего положений (на чертежах не показаны), что позволяет осуществлять более компактную сборку велосипеда в тележку. Привод 10 вращения колес может быть выполнен в виде двух оппозитно расположенных педалей 13 (фиг. 5 и фиг. 6), кинематически связанные с ведомой осью 14, на которой установлены два задних колеса 9, что является одним из возможных вариантов выполнения привода 10 вращения задних колес 9 велосипеда. Могут быть и другие варианты выполнения привода 10 задних колес 9. Например, в виде двух оппозитно расположенных рычагов 15 (фиг. 3 и фиг. 4), кинематически связанных с ведомой осью 14, на которой установлены два задних колеса 9, что является другим вариантом выполнения привода 10 вращения задних колес 9 велосипеда-тележки. Привод 10 вращения задних колес 9 может также выполнен в виде электрического двигателя 16 (см. фиг. 7), передающий вал 17 которого кинематический связан с задними колесами 9, а питающий аккумулятор 18, размещен на переднем звене 3 рамы 1, что является еще одним вариантом выполнения привода 9. На переднем звене 3 рамы 1 может быть смонтирован багажник 19 для перевозки грузов как в положении велосипед, так и в положении тележки. При сложении двухзвенного велосипеда в тележку необходимо освободить звенья 3, 4 от фиксатора (на чертежах не показан) и «cлoмaть» раму 1 так, чтобы звенья 3, 4 начали разворачиваться относительно шарнирных элементов 2. С другой стороны, шарнирные элементы 2 вместе со вторым звеном 4 перемещаются по сонаправленным концам первого звена 3 вверх. При этом идет сближение и соединение без зазоров звеньев 3 и 4, чем обеспечивается компактное сложение заявляемого велосипеда в тележку. Таким образом, решается поставленная техническая задача изобретения. Кроме того, освобождение переднего колеса 8 от привода 10 позволило освободить велосипедиста от необходимости одновременно согласовывать работу рук и ног при поворотах. За счет этого повышается управляемость заявляемого велосипеда. При сложении трехзвенного велосипеда в тележку необходимо произвести двойное «лoмaниe» рамы 1 по шарнирным элементам 2 и 12. При этом происходит плотное совмещение всех звеньев 3, 4 между собой без зазоров. В обоих положениях велосипеда: в сложенном и разложенном положение рамы 1 фиксируется с помощью фиксаторов (на чертежах не показаны). При двойном сложении также достигается поставленная задача - повышение компактности сложения и повышение управляемости заявляемого велосипеда.Now we consider the option of double folding the bicycle into a trolley (Fig. 2), in which the bicycle contains a frame 1 made of three articulated links, the third intermediate link 11 being installed between the first link 3 and the second link 4. Moreover, with the first link 3 the intermediate link 11 is connected by a cylindrical hinge element 2, and with the second link 4, the intermediate link 11 is connected by a cylindrical hinge element 12. The steering shaft 6 is made with the possibility of longitudinal movement relative to the steering column 5 and is equipped with clamps erhnego and lower provisions (not shown), which allows for a more compact assembly of the bicycle into a truck. The drive 10 of the rotation of the wheels can be made in the form of two opposite pedals 13 (Fig. 5 and Fig. 6), kinematically connected with the driven axle 14, on which two rear wheels 9 are mounted, which is one of the possible variants of the rear rotation drive 10 9 wheels of a bicycle. There may be other versions of the drive 10 of the rear wheels 9. For example, in the form of two opposed levers 15 (Fig. 3 and Fig. 4), kinematically connected with the driven axle 14, on which two rear wheels 9 are mounted, which is another option run drive 10 rotation of the rear wheels 9 of the bicycle trolley. The drive 10 of the rotation of the rear wheels 9 can also be made in the form of an electric motor 16 (see Fig. 7), the transmitting shaft 17 of which is kinematically connected to the rear wheels 9, and the supply battery 18 is located on the front link 3 of the frame 1, which is another an embodiment of the drive 9. On the front link 3 of the frame 1, a luggage rack 19 can be mounted for transporting goods both in the bicycle position and in the trolley position. When folding a two-link bicycle into a trolley, it is necessary to free the links 3, 4 from the latch (not shown in the drawings) and “break” the frame 1 so that the links 3, 4 begin to unfold relative to the hinge elements 2. On the other hand, the hinge elements 2 together with the second link 4 are moving along the codirectional ends of the first link 3 up. In this case, there is a rapprochement and connection without gaps of links 3 and 4, which ensures compact folding of the inventive bicycle in a trolley. Thus, the technical task of the invention is solved. In addition, the release of the front wheel 8 from the drive 10 allowed the cyclist to be freed from the need to simultaneously coordinate the work of arms and legs during turns. Due to this, the controllability of the claimed bike is increased. When folding a three-link bicycle into a trolley, it is necessary to double “break” the frame 1 by the hinged elements 2 and 12. At the same time, all links 3, 4 are tightly combined with each other without gaps. In both positions of the bicycle: in the folded and unfolded position of the frame 1 is fixed using clamps (not shown in the drawings). With double folding, the task is also achieved - increasing the compactness of folding and increasing the controllability of the claimed bike.
