FIELD OF THE INVENTION The invention relates to vehicles, namely hand trolleys for the transport of goods.

The aim of the invention is to expand the technological capabilities and simplify the design.

FIG. 1 schematically shows a trolley in position for the carriage of goods; in fig. 2 - the same, in the position for carrying goods (stretcher); in fig. 3 - the same, in the traveling position; in fig. 4 - the same, top view; in fig. 5 is a section A-A in FIG. 4 (at different positions of the handle); in fig. 6 is a section BB in FIG. 4 (at different boom positions); in fig. 7 - trolley in the folded position, view from the top-. . ca; in fig. 8 - trolley, bottom view.

The trolley consists of a cargo platform 1, made in the form of hinged parts to form a casing in the folded position. Under the loading platform position of the trolley shown in FIG. one). The handle 4 is shifted to a horizontal position, and the rods 8 are pulled out from platform 1 (Fig. 2). Then the levers 5 shift into the loading platform 1, having the handle 4 near it. Turning the cart up wheels 2, the latter is placed inside the platform 1 and fold it. Having folded the loading platform 1, the rods 8 are pushed into, the platform 1, while their curved cantilever ends 9 bend around the handle 4 and function as locks (Fig. 3). Carriage of the trolley by the handle 4. The trolley is moved to its working position in reverse order. So that the levers 5 and the rods 6 do not interfere with each other when placed inside the platform 1, they are mixed relative to each other (Fig. 4). The hinge 6 on the lever 5 is positioned so that when the lever 5 is fully pushed into the platform 1, it is positioned on the bend line

My 1 located wheels 2, mounted-20 platforms 1 (Fig. 5a). The tolls are folded on the swivel supports 3. To the cargo, the form 1, the extension is partially with a fully platform 1 attached handle 4 to the rod 8 from platform 1 (Fig. 56). With the means of levers 5, which contain a ball, this rod 8 is located only in one nira 6. When the handle 4 is located in one part of platform 1 and does not interfere with its folding plane with the loading platform 1, it does not burst. To move the trolley, the lever 5, the chugs 5, can be pushed inside the plate - it is pushed out of the platform 1 and deflected

forms. In this case, the handle 4 is located in the immediate vicinity of the loading platform 1. When the loading platform 1 is folded to the stowed position, the levers 5

up to the stop in the wall of the groove 7. At the same time, the hinge 6 allows bending of the levers 5 only in one direction. When using a trolley as a stretcher, the parts are bent at the location of the charolla and push the levers 5 inside the platform 1

6, which is installed in the middle of the lever 5. The handle 4 may be located in the immediate vicinity of the loading platform 1 and at the same time does not prevent the folding of the latter. To deflect the handle upwards (Fig. 1), there are notches 7 in the loading platform 1. The opposite end of the loading platform 1 is provided with two parallel rods 8 with curved cantilever ends 9. The rods 8 can be mixed inside the cargo board 35

and the rods 8 are fully extended from it (Fig. 5c).

Claims (1)

Invention Formula A hand truck containing a loading platform made in the form of two hinged parts to form in the folded position a casing, brackets mounted on the loading platform, mounted on turn brackets, and a handle associated with the loading platform, that, in order to expand the technological capabilities and simplify the design, the truck forms 1. The length of the rod 8 is greater than the width of the 40 supports with wheels and clamps of them in one part of the loading platform 1. When fully loaded into the load 1 Rod-hand platform 8 fixes the unfolded position of the platform. With a partially or fully extended rod 8 from the platform 1ka equipped with two rods with curved the cart can be folded in the field position. When the handle 4 is located in the same plane with the platform 1 and when the rods 8 are extended, the carriage turns into a stretcher (Fig. 2). The cart works as follows. The loading platform is transferred to the stowed position as follows (from the bottom ends located on the side of the cart opposite to the handle, the handle is connected to the arms pivotally articulated in their middle part, while the arms and rods are movable along the cart, and the length of the rods exceeds the length of each part of the load platform. . The trolley travel position is shown in FIG. one). The handle 4 is shifted to a horizontal position, and the rods 8 are pulled out from platform 1 (Fig. 2). Then the levers 5 are pushed into the loading platform 1, having the handle 4 near it. Turning the cart up wheels 2, the latter is placed inside the platform 1 and fold it. Having folded the loading platform 1, the rods 8 are pushed into, the platform 1, while their curved cantilever ends 9 bend around the handle 4 and function as locks (Fig. 3). Carriage of the trolley by the handle 4. The trolley is moved to its working position in reverse order. So that the levers 5 and the rods 6 do not interfere with each other when placed inside the platform 1, they are mixed relative to each other (Fig. 4). The hinge 6 on the lever 5 is positioned so that when the lever 5 is fully pushed into the platform 1, it is positioned on the bend line 0 0 platform 1 (Fig. 5a). The platform 1 is folded down, partly with the rod 8 completely out of platform 1 (Fig. 56). In this case, the rod 8 is located only in one part of the platform 1 and does not prevent its folding. To move the cart, the lever 5 is pulled out of platform 1 and deflected platform 1 (Fig. 5a). The platform 1 is folded down, partly with the rod 8 completely out of platform 1 (Fig. 56). In this case, the rod 8 is located only in one part of the platform 1 and does not prevent its folding. To move the cart, the lever 5 is pulled out of platform 1 and deflected up to the stop in the wall of the groove 7. At the same time, the hinge 6 allows bending of the levers 5 only in one direction. When using the trolley as a stretcher, the part ol push the levers 5 into the platform 1 35 and the rods 8 are fully extended from it (Fig. 5c). Invention Formula A hand truck containing a cargo platform made in the form of two sharniarno connected parts to form in the folded position of the casing, brackets mounted on the loading platform, mounted on the brackets pivot supports with wheels and clamps their crooked equipped with two rods with curved as well as a handle associated with the cargo platform, characterized in that, in order to expand the technological capabilities and simplify the design, the carriage supports with wheels and their retainers are equipped with two rods with curved cantilever ends located on the opposite side of the handle on the side of the trolley, the handle being connected to the arms pivotally articulated in their middle part, while the levers and rods are movable along the cart and the length of the rods exceeds the length of each part of the loading platform. we.
