ITFI20100023U1 - LIFTING ARM, DIRECTION AND TOWING FOR TROLLEY SUITCASES AND SHOPPING TROLLEYS. - Google Patents

Description

I. TABLE A

It is a mechanical arm, TAV 1 A, anchored to the frame of the shopping trolley or trolley case, both hereinafter abbreviated to trolley, positioned in such a way as to reduce the load on the person pulling the product in question, to effect of a balance naturally achieved during movement.

As can be deduced from the drawing in TAV. 1 B, the weight of the trolley is usually distributed between the wheels and the user. The application of the arm, TAV 1 A, allows to keep the trolley balanced on the wheels due to its more vertical posture. The added element, TAV. 1 C, where deemed appropriate by the user, can be quickly folded over the shape of the product.

2. DESCRIPTION OF THE INVENTION

a) TITLE

Lifting arm, directionality and towing for the trolley case and the shopping trolley

b) SUMMARY

It is a tubular structure, possibly telescopic, equipped with a handle, rigidly anchored to the frame of the trolley by means of light profiles and movable stops, mentioned TAV 1, which allows the user to maneuver the product without effort even when fully loaded. The innovation consists in replacing the conventional handle, formed by the frame of the product or part of it, with another angled of about 73 degrees with respect to the previous one, which, after having acted as a lever at the start with a movement from the top towards the low of its free end to position the trolley on the wheels only, it allows towing, guaranteeing the right balance in operation by construction. The device was made in the form of a prototype and was useful and robust.

c) DESCRIPTION

Given that the achievement of the trolley balance was advantageous in terms of mechanical achievements over any other solution intended to physically support the load, the proposed structure basically consists of three parts:

1) anchoring device to the frame: there are two types, one of which: • built with the trolley: it is a tubular structure, TAV 2, which covers the trolley handle to which the arm support is fixed. Said structure can slide along the handle to reach the operating position desired by the user and be fixed to it by means of a system of pins which rigidly connect the two parts. More simply, the tubular structure can be an integral part of the handle of the trolley to which the arm, TAV 2 A is applied. The height adjustment of the same is made directly by placing the handle at the appropriate height for the user.

• applied to a sign built without SOLCAR: it consists of two light alloy profiles, indicated with numbers 1 and 2 in TAV 3, which clamp the trolley handle by means of rods, numbers 3 and 4 in TAB 3, which, made integral to one of the two sections, they are held by a locking system inside the other section, Tav 4;

2) arm support: it consists of a U-shaped bracket, according to the model in Table 2, marked with the number 3 in Table 3 and Table S, fixed to the anchor and equipped with three holes on each side which serve respectively to house:

• the rotation pin of the arm to make the latter pass from the service position to the rest position, Tab 2 and number 4 in Tab 3; • the locking pin mounted on the arm to keep the arm stable in the exercise and rest positions, Table 2 and numbers 5 and 6 in Table 3. In particular, the position of the service hole is designed so that the arm reaches the tilt of 73 degrees with the frame; 3) arm: it consists of a tubular structure, Tav 2, 3, 5 possibly telescopic and with handle, equipped with an internal device formed by two levers, a spring and two buttons that allow the insertion of two pins in the holes described above , Tav 6. In this way a fast and safe locking of the arm to the whole assembly is ensured.

Since the arm, by construction, is already inclined to such an extent as to ensure the rotation of the trolley on the axis of the wheels when it is in motion, to ensure the adaptation of the SOLAR to the user's height it is sufficient to mount the support of the arm on the frame of the trolley at the level of the hand of the latter when the trolley is in the rest position,

d) Claims:

Considering the constructive simplicity of SOLCAR, the protections listed below are claimed:

° the principle of balance to develop handles suitable for pulling or pushing the trolley;

° the support of the arm on its support to reinforce the locking of the arm in its service position and achieve the lifting angle of the trolley from its rear support;

° the lifting angle to put the center of gravity of the trolley on the vertical of the wheels with a tolerance of 10 degrees;

° the anchoring system with levers, pins and spring to secure the arm to its support;

° the anchoring system to the frame of the trolley equipped with the SOLCAR
