FIELD OF TECHNOLOGY TO WHICH THE UTILITY MODEL RELATES

The utility model relates to the field of mechanical vehicles on wheels, namely to single-axle handcarts with one or more wheels, which the driver controls while walking side by side. Trolleys are intended for use in everyday life for the transportation of various goods during earthworks in garden plots, as well as when moving various goods.

BACKGROUND OF THE INVENTION

Known single-axle luggage trolley containing a frame with a cargo platform, a handle and wheels, while the frame is made in the form of interconnected beams with curved ends in a vertical longitudinal plane, each of which is connected to a rod with the middle part of its beam, forming a base for the cargo area ; the wheels are installed at the bend of the beams and are interconnected by a carrier axle, a support-brake strut is installed on the frame, equipped with coulters for interacting with the supporting surface (Description of the utility model to the patent of the Russian Federation No. 12817, IPC V62V 1/00, published on February 10, 2000).

ESSENCE OF THE UTILITY MODEL

Single-axle hand truck is made as follows. The basis of a single-axle handcart is a welded structure made of a profile square tube, consisting of right 1 and left 2 non-separable sidewalls, interconnected by transverse crossbars, front and rear with fixation 3. To eliminate deformation and breakage of the bottom, there are middle transverse crossbeams without fixation 4 , you can also make them fixed. The support rotation mechanism consists of a swivel pipe with a lever 5. The return spring 6 is connected at one end to the front crossbar 3, and the other end to the lever of the swivel pipe 5. The swivel pipe 5 rotates on axes 7. On the swivel pipe there is a pedal for turning the support 8 and a support 13. To install the body on the vertical side, there are hooks 9 on the upper part of the sidewalls. Brackets 10 are installed in the lower part of the sidewalls for fixing bicycle wheels 11, and handles 12 are fixed on the continuation of the upper part of the sidewalls (Fig. 1). Schematic diagram of the right sidewall 1 is shown in Fig. 2. The left sidewall is a mirror image of the right. The design of the cart provides for its quick assembly and disassembly. For this purpose, a larger square-section profile pipe is welded to sides a-a' and b-b'. For example, if the cross bars are made of 15x15 pipe, then a 20x20 pipe is welded. If the crossbar from the pipe is 20 × 20, then 25 × 25 is welded. This circumstance allows you to insert the crossbar into a larger pipe welded to the sidewall and fix it with anchor nuts. The base of a single-axle hand truck consists of a shaped square tube and consists of right and left non-separable sidewalls interconnected by transverse crossbars with fixation 3. The middle crossbars 4, designed to eliminate deformation and breakage of the plywood bottom when loading it with small cargo, are stacked on brackets 10 , welded to the right and left sidewalls, and not fixed (Fig. 3).

The bogie body is made of plywood sheets and consists of a bottom, two vertical side sheets and two vertical end sheets. The plywood bottom is laid on the cross bars 3 and 4 (Fig. 3) and follows the contour of the lower part of the metal structure. In FIG. 4, the contour of the plywood bottom is marked with a bold line. Grooves 14 are cut into the bottom, where the spikes 15 of the side and end vertical plywood sides enter, as shown in Fig. 5. The upper part of the vertical plywood sides is hung by hooks 9 on the upper pipes of the metal structure when moving the sheets from top to bottom (Fig. 1).

The handcart is equipped with a retractable (swivel) support 13. In the static position of the cart, the support occupies a position perpendicular to the ground surface and the edge of the cart can be supported on it. So that the support does not interfere with the movement of the cart, it rotates, as shown in Fig. 6 and occupies a position parallel to the plane of the bottom of the body.

The support rotation mechanism consists of a swivel pipe with a lever 5, rotating in axes 7; foot position control pedals 8; return spring 6, connected at one end to a fixed front crossbar 3, and the other - to the lever of the rotary pipe 5 (Fig. 6).

The principle of operation of the support mechanism. When a person acts on the pedal 8, the rotary support 13 begins to rotate, as shown in Fig. 6, causing the spring 6 to stretch. When the spring reaches a position passing through the axis of rotation of the rotary pipe, it becomes maximally stretched. Further rotation of the swivel pipe is not limited by anything, and it continues to rotate, but already under the action of a stretched spring that wants to compress. When the rotary pipe rotates, the support 13, which is rigidly fixed to it, also rotates and takes its extreme position, retracted or released.

The mountain brake is designed to prevent the rotation of the wheels of the cart, thereby preventing the movement of the cart on uneven terrain. The kinematics of the mountain brake is shown in Fig. 7. The mountain brake mechanism is located under the plywood bottom and consists of a brake pedal 16, its axis of rotation is located on a fixed front transverse bar 3, a locking lever 18, its axis of rotation is located on an unsecured transverse bar; intermediate rod 17, it connects the brake pedal 16 with the lock lever 18; as well as traction-blocker 19.

The principle of operation of the mountain brake. When a person acts on the brake pedal 16 with force F, the pedal, turning, pulls the intermediate rod 17, which, at the other end, sets in motion the lock lever 18. The lock lever, rotating, acts on the lock rod 19, which, moving apart, falls into the crotch between the spokes of the wheels. Thus, the wheels are blocked. To unlock them, it is necessary to press the brake pedal 16 with force R.

Single axle handcart design uses 18-20 inch bicycle wheels.

At present, the author has made a prototype of a single-axle handcart, which was handed over to the janitors for its testing in real conditions. It showed itself especially well when cleaning garbage chambers using big-bags.

The production of the proposed single-axle hand truck is industrially applicable, does not require complex technology, expensive materials for its manufacture.
