Abstract
The invention relates to the field of hand-operated transport means and can be used for transporting goods. A collapsible cart comprises a container having a handle, said container being mounted on a chassis. The container is pivotally connected to the chassis such that the chassis can be rotated about a shaft that runs along the edge of the bottom of the container, and the container has support lugs extending downward from the front end of the container, at the opposite end from the pivotal connection between the container and the chassis. The chassis includes an upper U-shaped frame and a lower U-shaped frame, two pairs of struts that are pivotally connected to the frames and that connect the frames on both sides of the container, each pair of struts forming a parallel linkage on each side, and an H-shaped brace consisting of a U-shaped part and two parts that are pivotally connected by one of their ends to the U-shaped part from both sides of a crossbar. The brace is pivotally connected by its upper ends to the back wall of the container and by its lower ends to the lower frame; closer to the front edge of the frame, the container is connected by a spring to one of the struts of the chassis. The result achieved by the invention is a decrease in the vertical dimensions of the cart when folded as a result of the chassis being collapsible.

Уровень техники The level of technology
Известна тележка, встраиваемая в багажник автомобиля (патент на изобретение RU 2372236 от 18.04.2008 г.), которая предназначена для сбора и транспортирования штучных упаковок, преимущественно при выполнении закупок товаров в супермаркете, содержащая грузовую корзину с ножками, с колесиками рояльного типа. К несущему корпусу тележки в скользящих опорах прикреплены два вала, на выступающих концах которых жестко укреплены правая и левая рукоятки управления и короткие рычаги, соединенные с пружинным амортизатором, соответственно справа и слева. Диагонально расположенные ножки жестко закреплены на соответствующих валах, а другая диагонально расположенная пара ножек сидит на валах шарнирно на скользящих втулках. Каждая пара ножек на одной стороне несущего корпуса соединена с помощью тяг, шарнирно соединяющих ножки и короткий рычаг одной стороны. Ножки посредством тяг складываются в ниши корпуса грузовой корзины, а тележка имеет жестко прикрепленные к несущему корпусу
корзины дополнительные ролики для вкатывания корзины в багажник автомобиля. Known trolley embedded in the trunk of a car (patent for invention RU 2372236 dated 04.18.2008), which is designed for collecting and transporting piece packages, mainly when purchasing goods in the supermarket, containing a cargo basket with legs, with piano wheels. Two shafts are attached to the carrying body of the trolley in the sliding supports, on the protruding ends of which the right and left control handles and short levers are rigidly fixed, connected to the spring shock absorber, respectively, right and left. The diagonal legs are rigidly fixed on the respective shafts, and the other diagonally located pair of legs sits on the shafts hinged on the sliding bushes. Each pair of legs on one side of the supporting body is connected by means of rods that pivotally connect the legs and a short lever on one side. The legs are folded into the baskets of the cargo basket by means of the body, and the trolley is rigidly attached to the carrying body. baskets additional rollers for inserting baskets into the trunk of a car.
Недостатком тележки является сложный механизм складывания ножек, включающий рычаги, валы, скользящие втулки и тяги. Кроме того, корпус грузовой корзины имеет ниши, предназначенные для складываемых ножек. Эти ниши выполнены за счет уменьшения внутреннего объема (емкости) грузовой корзины. Грузовая корзина с выступающими внутрь поверхностями менее удобна для складирования в нее каких-либо предметов, в том числе и товаров в магазине. Дополнительные ролики для вкатывания корзины в багажник автомобиля жестко прикреплены к несущему корпусу корзины. Такая конструкция требует наличия аппарелей для вкатывания тележки в багажник автомобиля, что усложняет конструкцию. The disadvantage of the trolley is a complex mechanism for folding the legs, including levers, shafts, sliding bushings and traction. In addition, the body of the cargo basket has niches designed for foldable legs. These niches are made by reducing the internal volume (capacity) of the cargo basket. A cargo basket with protruding inside surfaces is less convenient for storing in it any objects, including goods in the store. Additional rollers for inserting the basket into the trunk of the car are rigidly attached to the carrying body of the basket. This design requires a ramp for racking the cart into the trunk of the car, which complicates the design.
Известна складная тележка, содержащая емкость (корзину), консольно установленную на шасси, включающее две горизонтальные балки с колёсами и шарнирно соединенные с ними и с задней частью емкости вертикальные стойки, а также электропривод, обеспечивающий складывание шасси (US 2014369801 А1, 18.12.2014). Known folding trolley containing capacity (basket), cantilever mounted on the chassis, including two horizontal beams with wheels and pivotally connected with them and with the rear of the tank vertical stands, as well as an electric drive that folds the chassis (US 2014369801 A1, 12/18/2014) .
Тележка облает следующими недостатками. Консольное расположение ёмкости относительно опоры (шасси) значительно повышает требования к прочности конструкции опоры, что ведет к её усложнению и утяжелению. При этом конструкция имеет низкую устойчивость и жесткость в продольной плоскости. Левая и правая опоры не связаны конструктивно между собой. Это ведет к уменьшению общей жесткости конструкции и устойчивости в поперечной плоскости. Многоступенчатая процедура складывания тележки подразумевает несколько этапов с расфиксацией и подъемом
каждой опоры отдельно. Это снижает удобство использования тележки. Сложность и разнообразие различных необходимых компонентов конструкции, таких как стойки, ролики, амортизаторы, пружины, фиксаторы, электродвигатель с червячной передачей, система электропитания и т.д. сильно усложняет конструкцию, удорожает её стоимость, а также уменьшает надежность и ремонтопригодность тележки. The cart has the following disadvantages. The cantilever arrangement of the tank relative to the support (chassis) significantly increases the requirements for the support structure strength, which leads to its complication and weighting. In this case, the design has low stability and rigidity in the longitudinal plane. Left and right supports are not constructively interconnected. This leads to a decrease in the overall rigidity of the structure and stability in the transverse plane. Multistep trolley folding procedure involves several steps with unlocking and lifting each support separately. This reduces the ease of use of the cart. The complexity and variety of various necessary components of the structure, such as racks, rollers, shock absorbers, springs, clamps, worm gear motor, power supply system, etc. greatly complicates the design, increases its cost, and also reduces the reliability and maintainability of the trolley.
Наиболее близкой к предложенной является складная тележка, содержащая емкость, установленную на основании, имеющем ножки с колесами, емкость соединена с основанием шарнирно с возможностью поворота основания вокруг оси, проходящей вдоль края дна емкости, таким образом, что в сложенном состоянии по меньшей мере по одной ножке основания расположены с внешней стороны каждой из двух противоположных стенок емкости, причем емкость имеет направленные вниз опорные выступы со стороны, противоположной шарнирному соединению с основанием (RU 168969 U1 , опуб. 28.02.2017). В тележке отсутствуют дополнительные приспособления (аппарели) для загрузки ее в багажник автомобиля вследствие обеспечения непосредственного взаимодействия опорных выступов с багажником автомобиля. Кроме того, тележка имеет простую конструкцию за счет уменьшения числа элементов механизма складывания, а также имеет больший полезный объем за счет того, что сложенные ножки размещаются за пределами емкости. Closest to the proposed is a foldable carriage containing a container mounted on a base having legs with wheels, the container is connected to the base pivotally with the possibility of rotation of the base around an axis passing along the edge of the bottom of the container, so that in the folded state at least the base of the base is located on the outer side of each of the two opposite walls of the container, and the container has downwardly directed support lugs on the side opposite to the hinged connection with the base (RU 168969 U1, published Feb 28, 2017) In the trolley there are no accessories (ramp) for loading it into the trunk of a car due to the direct interaction of the support lugs with the trunk of the car. In addition, the cart has a simple design by reducing the number of elements of the folding mechanism, and also has a larger useful volume due to the fact that the folded legs are placed outside the container.
Недостатком тележки является то, что в сложенном состоянии высота тележки может быть не менее ιΔ от высоты тележки в разложенном состоянии. Это накладывает существенные ограничения или на высоту загрузки тележки или на габариты (высоту) багажного отделения транспортного средства, в которое загружается тележка.
. The disadvantage of the cart is that when folded, the height of the cart may be at least ι ∆ from the height of the cart in the unfolded state. This imposes significant restrictions either on the height of the load of the trolley or on the dimensions (height) of the luggage compartment of the vehicle into which the trolley is loaded. .

Это позволяло бы сделать тележку подходящей к подавляющему большинству автомобилей - от внедорожников и кроссоверов - до хэтчбеков и седанов. The technical problem solved by the proposed trolley is that with an increased loading height of the trolley (the boot floor level of most crossovers and SUVs is 700 - 750 mm), make the dimensions of the trolley in the folded state be the same or even smaller, especially its height (up to 400 mm). This would make the cart suitable for the vast majority of cars - from SUVs and crossovers - to hatchbacks and sedans.

двумя с обеих сторон тележки) с одной из стоек шасси, которая растянута в разложенном положении тележки. The technical problem is solved by a folding cart containing a container with a handle mounted on a chassis, with which the container is connected pivotally with the possibility of rotating the chassis around an axis extending along the edge of the bottom of the container, the capacity having downward supporting lugs from the front side opposite to the hinged connection with the chassis, at the same time, according to the utility model, the chassis includes an upper U-shaped frame pivotally connected to the tank, a lower U-shaped frame on which the wheels are mounted, two pairs of pillars pivotally connected to the frame connecting the frames on both sides of the tank with a pair of racks on each side with the formation of parallelogram mechanisms, and an H-shaped brace consisting of a U-shaped part, and two parts pivotally connected at their ends with a U-shaped part on both sides from the crossbar, while the strut is pivotally connected by its upper ends to the container from the rear wall, and its lower ends to the lower frame closer to the front edge of the lower frame than the junction of the racks to the lower frame, while the capacitance is connected by a spring (or two on both sides of the trolley) with one of the landing gear legs, which is stretched in the unfolded position of the trolley.
Кроме того, для уменьшения трения при загрузке тележки в транспортное средство и при ее выгрузке по меньшей мере один опорный выступ имеет на конце ролик. In addition, to reduce friction when the trolley is loaded into the vehicle and when it is unloaded, at least one bearing lug has a roller at the end.
Технический результат, достигаемый предложенным техническим решением, заключается в уменьшении габарита тележки в сложенном состоянии в высоту за счет выполнения шасси складным.

Пример осуществления изобретения An example embodiment of the invention
Тележка складная содержит емкость 1 , например, в виде корзины, которая может быть изготовлена из металла, пластика, дерева или другого подходящего материала. Емкость 1 шарнирно соединена с шасси с возможностью поворота шасси вокруг оси 2, проходящей вдоль края дна емкости 1. Шасси включает верхнюю П- образную раму 3, шарнирно соединенную с емкостью 1 , и нижнюю П- образную раму 4, на которой установлены колёса 5. Перекладины обеих рам 3 и 4 расположены с передней стороны тележки, а с задней стороны рамы не имеют перекладины для свободного похода емкости 1 при складывании тележки. Рамы 3 и 4 с боковых сторон соединены
стойками, по паре стоек 6 и 7 с каждой стороны, с образованием с каждой стороны тележки параллелограммного механизма. Стойки 6 и 7 образуют с боковыми сторонами нижней рамы 4 острые углы с вершинами, обращенными в сторону задних концов рамы 4. Foldable trolley contains container 1, for example, in the form of a basket, which can be made of metal, plastic, wood or other suitable material. The container 1 is pivotally connected to the chassis with the possibility of rotation of the chassis around the axis 2, passing along the edge of the bottom of the container 1. The chassis includes an upper U-frame 3, pivotally connected to capacity 1, and a lower U-frame 4 on which the wheels 5 are mounted. The crossbars of both frames 3 and 4 are located on the front side of the cart, and on the back side of the frame do not have a crossbar for the container 1 to freely move when the cart is folded. Frames 3 and 4 are connected to the sides racks, a pair of racks 6 and 7 on each side, with the formation of a parallelogram mechanism on each side of the cart. Racks 6 and 7 form with the sides of the lower frame 4 sharp corners with the tops facing the rear ends of the frame 4.
Тележка также включает складывающийся Н-образный подкос The cart also includes a folding H-shaped strut
8, состоящий из П-образной части 9, шарнирно соединенной своими концами с емкостью 1 с её задней стенкой, и двух нижних частей 10, шарнирно соединенных своими верхними концами с П-образной частью 8 с обеих сторон от её перекладины, которая служит ручкой 11. В другом варианте нижняя часть подкоса 8 может быть выполнена П-образной и шарнирно соединенной с двумя верхними частями (на чертежах не показано). Подкос 8 снабжен фиксатором (на чертежах не показан), удерживающим его от сложения в разложенном положении тележки. Своими нижними концами нижние части 10 соединены с нижней рамой 4 в местах, расположенных ближе к переднему краю нижней рамы 4, чем места соединения стоек 5, 6 с нижней рамой. При этом нижние части 10 подкоса 8 образуют острый угол с боковыми сторонами нижней рамы 4, вершина которого направлена в сторону переднего края рамы 4. Емкость 1 соединена пружиной 12 с одной из стоек 6 шасси. В разложенном состоянии тележки пружина 12 растянута. Могут быть две пружины 12 с двух сторон тележки. 8, consisting of a U-shaped part 9, pivotally connected at its ends with a tank 1 with its rear wall, and two lower parts 10, pivotally connected at its upper ends with a U-shaped part 8 on both sides of its crossbar, which serves as a handle 11 In another embodiment, the lower part of the strut 8 may be made U-shaped and pivotally connected to the two upper parts (not shown in the drawings). The strut 8 is provided with a lock (not shown in the drawings), keeping it from collapsing in the unfolded position of the carriage. With their lower ends, the lower parts 10 are connected to the lower frame 4 in places located closer to the front edge of the lower frame 4 than the junction of the posts 5, 6 with the lower frame. In this case, the lower parts 10 of the strut 8 form an acute angle with the lateral sides of the lower frame 4, the apex of which is directed toward the front edge of the frame 4. The container 1 is connected by a spring 12 to one of the landing gear 6. In the unfolded state of the cart, the spring 12 is stretched. There may be two springs 12 on both sides of the cart.
Шасси выполнено таким образом, что расстояние между боковыми частями рам 3, 4 и стойками 5, 6, расположенными по разные стороны от емкости 1 , больше ширины емкости 1 , так что при повороте шасси вокруг оси 2 они располагается снаружи емкости 1. Возможность вращательного движения основания 3 и возможность вращательного движения емкости 1 взаимно ограничены конструкциями основания 3 и емкости 1. Для обеспечения
возможности приведения тележки в разложенное состояние («емкость сверху шасси») и обеспечения возможности приведения тележки в сложенное состояние, между положением для тележки в разложенном состоянии («емкость сверху шасси») и положением тележки в сложенном состоянии, угол поворота шасси относительно емкости 1 составляет приблизительно 180 градусов. Емкость 1 имеет ручку 13 предназначенную для управления тележкой. The chassis is designed so that the distance between the side parts of the frames 3, 4 and racks 5, 6, located on opposite sides of the tank 1, is greater than the width of the tank 1, so that when the chassis rotates around the axis 2, they are located outside the tank 1. The possibility of rotational movement the base 3 and the possibility of rotational movement of the tank 1 are mutually limited to the structures of the base 3 and tank 1. To ensure the possibility of bringing the trolley into the unfolded state (“capacity on top of the chassis”) and enabling the trolley to be folded in, between the position for the trolley in the unfolded state (“capacity on top of the chassis”) and the position of the trolley in the folded state, the angle of rotation of the chassis relative to capacity 1 is about 180 degrees. The container 1 has a handle 13 designed to control the cart.
Для того чтобы обеспечить процесс загрузки тележки на поверхность, находящуюся выше чем поверхность, на которой находятся колеса 5, например, в багажное отделение транспортного средства (например, автомобиля), тележка снабжена по крайней мере двумя угловыми опорными выступами 14. Выступы 14 направлены вниз и выполнены предпочтительно на нижней части (дне) емкости 1 в месте ее примыкания к боковым стенкам и передней стенке емкости 1, противоположной задней стенке емкости 1 , со стороны которой находятся места 2 шарнирного соединения емкости 1 с верхней рамой 3 шасси. Для уменьшения трения при использовании в качестве опоры по меньшей мере один из выступов 14 снабжен роликом 15. In order to ensure that the trolley is loaded on a surface higher than the surface on which the wheels 5 are located, for example, in the luggage compartment of a vehicle (for example, a car), the trolley is equipped with at least two corner support lugs 14. The projections 14 are directed downwards and preferably made on the lower part (bottom) of the container 1 in the place of its junction to the side walls and the front wall of the container 1 opposite to the rear wall of the container 1, on the side of which there are 2 swivel points of the container 1 s erhney 3 frame chassis. To reduce friction when used as a support, at least one of the projections 14 is provided with a roller 15.
Тележка используется следующим образом. The cart is used as follows.
В разложенном состоянии тележки емкость 1 (корзина) опирается на ось 2, верхнюю раму 3 шасси и подкос 8, который зафиксирован в разложенном состоянии. In the unfolded state of the cart capacity 1 (basket) rests on the axis 2, the upper frame 3 of the chassis and the strut 8, which is fixed in the unfolded state.
При загрузке тележки на поверхность, находящуюся выше, чем поверхность получающая воздействие от колес 5, например, в багажное отделение транспортного средства, тележку подвозят к транспортному средству, нажимают на ручку 13, чтобы поднялась передняя часть тележки, заводят опорные выступы 14 на поверхность загрузки. Поддерживая емкость 1 одной рукой за ручку 13,
пользователь одновременно расфиксирует подкос 8 и тянет его за ручку 11 на себя и вверх, поворачивая его относительно емкости 1. За счет энергии пружины 12 шасси поворачивается на оси 2 относительно емкости 1 и одновременно складывается своими параллелограммными механизмами. When loading a trolley on a surface that is higher than the surface receiving the impact from the wheels 5, for example, in the luggage compartment of the vehicle, the cart is brought to the vehicle, press the handle 13 to raise the front part of the cart, bring the supporting lugs 14 to the loading surface. Holding the container 1 with one hand on the handle 13, The user simultaneously unscrews the strut 8 and pulls it by the handle 11 towards itself and upwards, turning it relative to the container 1. Due to the energy of the spring 12, the chassis rotates on axis 2 relative to the container 1 and at the same time folds with its parallelogram mechanisms.
При достижении поворота шасси примерно на 180 градусов тележка становится компактной, ее габариты сопоставимы с габаритами емкости 1 , благодаря чему ее можно загрузить на поверхность транспортного средства дальше вперед и/или повернув ее вокруг вертикальной оси, проходящей через правую или левую передние опорные выступы 14. When the chassis is rotated approximately 180 degrees, the cart becomes compact, its dimensions are comparable to the dimensions of tank 1, so that it can be loaded onto the surface of the vehicle further forward and / or turning it around a vertical axis passing through the right or left front support lugs 14.
При выгрузке тележки все действия осуществляются в обратном порядке: поворачивают сложенную тележку на одном из опорных выступов 14, вращают шасси на 180 градусов за ручку 11 до его раскладывания и опоры емкости 1 на ось 2 и верхнюю раму 3, опускают тележку до опоры на два задние колеса 5, выводят опорные выступы 14 с поверхности загрузки и опускают тележку до опоры на все колеса 5. When unloading the trolley, all actions are carried out in the reverse order: the folded cart is turned on one of the supporting lugs 14, the chassis is rotated 180 degrees by the handle 11 until it is unfolded and the container 1 is supported on the axle 2 and the upper frame 3, the cart is lowered to two backs the wheels 5, remove the support lugs 14 from the loading surface and lower the carriage to the support on all the wheels 5.
Таким образом, общие габариты тележки в сложенном состоянии близки к полезному объему ёмкости 1, что позволяет эффективно использовать пространство внутри транспортного средства или места хранения тележки. Thus, the overall dimensions of the trolley in the folded state are close to the useful volume of capacity 1, which allows efficient use of the space inside the vehicle or the storage location of the trolley.
Кроме того, конструкция тележки позволяет осуществлять загрузку тележки вместе со своим содержимым из положения в разложенном состоянии на шасси - в положение в сложенном состоянии в багажнике транспортного средства практически одним движением, не отрывая рук от ручки тележки 13 и ручки 11 подкоса 8. In addition, the design of the cart allows you to load the cart with its contents from the unfolded position on the chassis to the folded position in the trunk of the vehicle with almost one movement, without taking your hands off the handle of the cart 13 and the handle 11 of the brace 8.
При этом загрузка быстра и удобна, т.к. значительная часть веса
тележки с содержимым сразу передается на поверхность загрузки, а прилагаемые усилия кратковременны.
At the same time loading is fast and convenient, since significant weight carts with contents are immediately transferred to the loading surface, and the applied efforts are short-term.
