Description

The utility model relates to a multi-purpose hand-held universal trolley designed for the transportation of household goods. Multifunctional universal trolley, hereinafter MUT, can be used in several versions.

A well-known universal trolley (Patent RU No. 2552407 C1, IPC В62В 1/04, ВВВ 5/00 - 06/10/2015, Bull. No. 16), consisting of a frame, two wheels with an axle, a U-shaped tubular handle, a cargo tank with a lid . The frame is made of three U-shaped pipes and three connecting rods, forming a geometrically rigid spatial triangle, providing a solid connection for the universal performance of various functions: rolling functions, sliding functions, functions of a chair with an inclined back and the functions of a cargo tank with a hinged lid. The disadvantage of a universal trolley is that it is impossible to transport fragile, easily breaking objects, it is impossible to transport easily crushed fruits and vegetables. In the case when it becomes necessary to transfer the trolley from the rolling function to the sliding function and vice versa, i.e. practically the trolley needs to be turned over 120 ° ÷ 150 °. And it turns out that the bottom of the trolley is almost at the top of the transported cargo. And then there is a need to somehow fix the load, so that eventually porridge does not form. The disadvantage of the prototype is a rigidly mounted handle at an angle of 27 °, which involves holding the center of gravity of the trolley directly above the axis of the wheel. But after all, this angle may not be suitable for a person with a height of 1 m 50 cm, it should be larger, and for a person with a height of 1 m 90 cm this angle should be less. And to transport cargo over long distances and with great weight, this trolley is inconvenient and tedious to operate. Therefore, during the movement, people are forced to stop from time to time and squat on a trolley in order to take a breath, gain strength and move on. The bulk of people who use road carts are summer residents, pensioners, the elderly, who sometimes walk several kilometers on foot in order to reach the summer cottage, carrying various loads on these carts. This patent is taken as a prototype.

The objective of the claimed utility model is the creation of a multi-functional hand-held universal trolley used in three versions.

The proposed multi-purpose universal trolley will greatly facilitate the life of a summer resident, carrying various loads and even the summer resident himself. MUT can be useful for people who are not disabled, but suffer from diseases of the lower extremities, which long-term walking is contraindicated, who experience pain, tiredness when walking. MUT may be useful to fishing enthusiasts, mushroom pickers. MUT can be used as a recreational entertainment facility for both adults and children, for walks along forest paths, in picturesque places.

MUT as a vehicle has several advantages over such vehicles as a bicycle, moped, scooter. When folded, it can easily fit in the trunk of a car, can easily fit in the space under the seat of an electric train. In the case of a complete exhaustion of the energy of the batteries, the MUT can be used as an ordinary hand truck.

Option one, like the usual widespread shopping cart of FIG. one.

The dimensions are close to the existing trucks, with the only difference being that there is a third steering wheel and instead of a U-shaped handle a bicycle type steering wheel is used, which is pivotally mounted to the steering column and can be rigidly fixed within 180 °, in the plane of rotation of the steering wheel. And it allows you to set a convenient height of the steering wheel, based on the height of the person.

The second option, as a self-propelled trolley for transporting only the cargo of FIG. 2. The movement provides an electromechanical drive mounted on one of the wheels.

Since the MUT is designed for use in human traffic, along sidewalks, along pedestrian paths, and its speed is limited to 8-15 km / h, and the total mass does not exceed 100 kg, an engine with a power of 500-1000 watts is quite suitable. This engine should provide a smooth ride, a wide range of speeds and should be powered by a modern energy-intensive battery. As a drive, it is proposed to use a power tool with replaceable batteries (a common screwdriver), and with a control button on the steering wheel. The power reserve of the MUT with such a drive, equipped with several pairs of replaceable batteries, can reach from one or two km depending on the mass of the load and the quality of the road surface. And to go an even greater way at the MUT, it is possible to install more energy-intensive batteries from gyro scooters.

The third option, as a self-propelled trolley for transporting a small amount of cargo and the driver of FIG. 3. For greater stability, a third steered steering wheel extends telescopically along the rails from the main frame and is rigidly fixed by a latch. Next, a bicycle-type saddle is mounted on the main frame and pulled together with a clamp. As a result of a simple operation, a compact controlled vehicle capable of transporting a person is obtained from a cargo trolley. Providing silent and smooth movement, maneuvering in a human stream.

A multifunctional universal trolley is shown in FIG. 4 in two projections of the frontal and profile, in the variant of transportation of only cargo. MUT includes the main frame 1, the front telescopically extendable steering part 2, the steered wheel 3, the driving wheel 4, the driven wheel 5, drive 6, steering wheel 7.

In FIG. Figure 5 shows the use of the MUT for transporting a small amount of cargo and the cargo owner himself. Mounted saddle 8 bicycle type. Steering wheel 7 is fixed in the sitting position.

In FIG. 6 in three projections shows the main frame in more detail. It is a welded structure made of a thin-walled pipe of rectangular cross section. It includes a pipe 9 of rectangular cross section, covering the entire perimeter of the frame, a through pipe 10 of rectangular cross section, located in the center of the frame, where the rod of the front telescopically extendable part is inserted, bearing plates 11 of the driven wheel 5, bearing plates 12 of the driving wheel 4, latch 13, which fixes the extremely extended and extremely retracted position of the rod, the pipe 14 for mounting the seat 8, a metal sheet 15 covering the entire upper part of the frame on which the transported cargo is placed. At the bottom of the frame there is a box casing 16, consisting of two sections. In one there is a wheel gear 17 and a screwdriver 18. In the other, spare and used batteries 19 of the screwdriver 18.

In a section AA shows the layout of the drive 17, 18, the batteries 19 inside the casing 16. In the front and rear of the casing 16, slotted holes for ventilation are made. The rear wall of the casing 16 is designed as an opening, for access to the screwdriver 18 and the batteries 19. Since the screwdriver 18 is supposed to be used for its intended purpose. That in our case, the installation and fastening of the screwdriver 18 is provided quick-detachable. The end of the input shaft of the wheel gear 17 is made in the form of a hexagon. And the screwdriver spindle 18 in our case also has a hexagonal hole of the same size. That easily allows you to connect a screwdriver 18 and a wheel gear 17. Next, the handle of the screwdriver 18 is placed on the cabinet, in which the recesses are made that copy the shape of the handle. Then the handle is pressed by the cover with two bolts. The lid also has recesses on the inside that copy the shape of the handle. Using a screwdriver 18 allows the MUT to move in both directions (forward or backward), it also allows you to limit the torque on the shaft of the drive wheel 4, allows you to limit the speed of movement. In FIG. 7 in three projections shows the front steering part in more detail. It includes a rod 22, made of a thick-walled rectangular tube, a pipe 23, which acts as a bearing housing of the steering fork 24 of a bicycle type, the wing 25 of the front steered wheel 3, which protects against water splashes, while serving as a support for the driver’s legs. When installing the front steering part on the main frame, the stem 22 is inserted into the through pipe 10, providing a snug fit. But at the same time, maintaining a slight sliding of the rod 22 inside the through pipe 10.
