Lowered bidirectional trolley

Abstract

A bidirectional trolley (1) comprising a drawbar (Abstract2), two pivoting front wheels (6, 6′) a push handle (3), a loading and unloading plan (4) for a box (5) for moving items. The bidirectional trolley comprises a rotary system (10), placed in the rear portion of the trolley (1), and comprising two non-pivoting wheels (8′, 8″) placed on the same horizontal axis, a pivoting wheel (8) placed at 45° with respect to the other two non-pivoting wheels (8′, 8″) and a hook (12), configured for assuming a resting position in which it is completely retracted under the plan (4) between the two non-pivoting wheels (8′ and 8″), in order to permit to an operator to approach the most to the box (5) for moving items, for an easy unloading and loading of the box (5) itself.

Claims

1. A bidirectional trolley (1) comprising a drawbar (2), two pivoting front wheels (6, 6′) a push handle (3), a loading and unloading plan (4) for a box (5) for handling items, which comprises a handling system (10) placed in the rear part of the bidirectional trolley (1), and comprising two non-pivoting wheels (8′, 8″) placed on the same horizontal axis, a pivoting wheel (8), placed at 45° with respect to two other non-pivoting wheels (8′, 8″) and a hook (12), configured to assume a resting position in which it is completely retracted under the plan (4), between the two non-pivoting wheels (8′ and 8″), in order to permit to an operator to approach the box for moving items in the best way, for an easy loading and unloading of the box (5) itself.

2. The bidirectional trolley (1) according to claim 1, wherein the hook (12) is configured for being extracted in a working position and taken at the height of a plan (4), to permit to hook a second trolley (1).

3. The bidirectional trolley (1) according to claim 1, is configured in such a way that when the hook (12) is in a working position, the rotation both of the two non-pivoting wheels (8′ and 8″) and of the pivoting wheel (8) by an angle of 90° is avoided.

4. The bidirectional trolley (1) according to claim 1, is configured in such a way that when the hook (12) is in a resting position, they can rotate both the two non-pivoting wheels (8 and 8″) and the pivoting wheel (8), and to permit a lateral translation of the bidirectional trolley (1) itself.

5. The bidirectional trolley (1) according to claim 1, wherein said drawbar (2) comprises a pedal of a brake (7) which acts on a blocking mechanism of the front pivoting wheels (6, 6′).

DETAILED DESCRIPTION OF THE INVENTION

(9) With reference to the above figures, the subject of the present invention is a lowered bidirectional trolley 1. said trolley 1 permits to move the containers at a height of 50 mm from the ground, instead of 250 mm, maintaining at the same time the height of the hook at the common height of 200 mm. the trolley 1 comprises a front movable drawbar 2, a push handle 3 and a loading and unloading plan 4, on which a box for moving items 5 is placed, as can be seen in FIGS. 6 and 7, the box 5 is placed on the trolley 1, such as its support feet 5′ on the ground are external to the plan 4.

(10) Within the whole present description, with “front side of the trolley” is the side proximate to the push handle 3, whereas the rear side is the one distal to the push handle 3. it is clear, on the other hand, as left side and right side of the trolley the ones corresponding to the arms of an operator, placed in a rear position, with respect to the same trolley, and which handles the handle 3.

(11) The drawbar 2 comprises two front wheels 6, 6′ which are pivoting and a pedal of the brake 7, acting on the blocking mechanism of the front pivoting wheels, by means of a system of levers, connecting rods and cams, of the known type, and therefore it is not shown in the annexed figures.

(12) The rear part of the trolley 1 comprises a rotary system 10, comprising three wheels 8, 8′, and 8″ mounted on a plate 11. such rotary system 10 comprises two non-pivoting wheels 8′ and 8″. placed on the same horizontal axis, and a pivoting wheel 8, placed at 45° with respect to the other two wheels 8′, 8″.

(13) The rotary system 10 also comprises a hook 12 directly connected with the plan 4, in a working position, such hook 12 takes a resting position in which it is retracted under the plan 4, between the two wheels 8′ and 8″, as shown in FIG. 4. in such resting position, as shown in FIGS. 6 and 7, the rear part of the trolley 1 is completely free, and the operator is able easily to approach the box 5, in order to perform the unloading of the box 5 itself.

(14) In a working position, the hook 12 is extracted and taken at the height of the plan 4. in such position, as shown in FIG. 3, the trolley can be connected to a second trolley, to be inserted in series in a sequence of trolleys, in the working position, the hook 12 is fixed to the trolley, as shown in FIG. 3, which avoids a rotation of the rotary system 10. in other words, it is avoided the rotation both of the non pivoting wheels 8′ and 8″, and of the pivoting wheel 8. when the hook 12 is inserted in the working position, the rotary system 10 can be actuated, and both the non pivoting wheels 8′ and 8″ and the pivoting wheel 8, and to permit a lateral translation of the trolley 1. the push handle 3 fixed on the drawbar 2 permits the handling and the pushing of the trolley 1 in the desired direction, in the translating and positioning step of the trolley in working areas with few space or bound, it is therefore sufficient a single maneuver, the steering of the trolley is made without moving the same.

(15) Although at least one exemplary embodiment has been presented in the summary and in the detailed description, it must be understood that there exists a large number of variants falling within the scope of protection of the invention, furthermore, it must be understood that the embodiment or the embodiments presented are only examples that do not intend to limit in any way the scope of protection of the invention or its application or configurations, on the contrary, the brief description and the detailed description provide the skilled man with a convenient guide for implementing at least one exemplary embodiment, as it is clear that numerous variations can be made in the function and assembly of the elements described therein, without departing from the scope of protection of the invention as established by the attached claims and their technical-legal equivalents.
