Description

REMOVABLE LATERAL TRACTION DEVICE

FOR CASTER CONTAINERS

Field of the invention

The present invention relates to a removable lateral traction device of wheeled container of type suitcase or trolley.

The present invention relates to the field of luggage with built-in rolling means and vehicles with arms for the transport of goods. It relates particularly to an additional handle device adaptable to a large number of trolleys and suitcases existing commercially, for ease of use.

Brief description of the prior art

Wheeled luggage or shopping carts are, in the most common use, pulled by handles, inverted U-shaped, placed in the central axis of their container. In use, the user tows this type of luggage next to him, with one hand, in an uncomfortable position and for his arm, shoulder and back. Indeed, when the user of a wheeled luggage provided with an inverted U-shaped handle moves while pulling his luggage, he must make a slight rotation of the shoulders with respect to the axis of his spine so that the shoulder of the arm towing the baggage is oriented towards the rear of its body in the direction of the handle of said luggage. The muscles of the back of the shoulder and the arm are solicited simultaneously, and all the more strongly that the luggage is heavy, so that the vertical bars of the inverted U are parallel to the direction of travel of the user of said luggage. In addition, when a delicate passage occurs on its path, as when crossing with another pedestrian on a narrow sidewalk, the user of one of these luggage has great difficulty in pulling the latter behind him. Indeed, it must move almost laterally (crab) to pass his luggage on his own steps, which is inconvenient and dangerous because the axis of the user's gaze is no longer in the direction of travel.

To overcome these drawbacks, devices, having a handle that is not located in the central axis of the baggage but offset from it, which we will now call the side handle, have been developed, as illustrated by FIG. DE8230220 patent in which a shopping trolley is equipped with a pull handle, rotatable about a vertical axis, which can be oriented laterally with respect to the central axis of said carriage. However, in this device, said handle just has the possibility of being placed, after use in a lateral position, in the axis of the luggage on top of it; which evokes a problem of size of the handle. In addition, this handle is intended to be irremovable of this truck, it can not fit on other luggage, this illustrates a disadvantage of adaptability of this type of handle luggage or trolleys existing commercially.

Patent DE102010000 has an irremovable rotating handle. This device is in the axis of the carriage and does not allow lateral offset.

Another device having a so-called lateral handle is described in patent US5339934; again the imagined device has the disadvantages of space and adaptability to other luggage, cited above. Indeed in its design this device has a handle, fixed in the center of one of the faces of a rolling luggage, can, thanks to a ball joint, be inclined in a lateral position relative to the axis of said luggage. This handle consisting of a T-bar is irremovable from its luggage because of its anchoring to said ball mentioned above.

To solve these congestion problems, other devices such as those illustrated in the patents WO9807344 and WO9730607 have removable handles, which, as in the second case, can adapt to different luggage existing commercially, but which however does not do not have the advantage of a lateral offset.

The prior art therefore does not satisfactorily solve the problem of congestion handles luggage or trolleys with a side handle or that of their adaptability to other luggage existing commercially.

Summary of the invention

The present invention overcomes these drawbacks, by proposing a handle device adaptable to most shopping carts and suitcases for towing said wheeled luggage behind you, with a lateral grip rather than dorsal.

It is a wheeled container traction device (1) comprising a gripping means (2) connected by a rigid connection means (3) to a removable fastening means (5) to at least one one of the constituent elements (12) of the wheeled container (9).

Preferably, said rigid connection means (3) comprises at least one complementary connecting means (4), the assembly constituting a connecting means. Advantageously, said removable attachment means (5) comprises a holding means (11) of said constituent element (12) of the wheeled container and connection means (6) to said rigid connecting means (3).

According to one embodiment, said removable attachment means (5) comprises a means for locking said rigid connection means (3) in said connecting means (6).

According to another embodiment, said removable fixing means (5) comprises a means of rotation between said holding means (11) and said connection means (6).

According to a variant, said gripping means (2) comprises means of rotation the binder to said rigid connection means (16) according to at least one axis of rotation. Said gripping means is hollow and fits on the rigid connecting means (3) when folded.

According to another variant, said removable fixing means (5) comprises at least one reversible opening means (13)

Detailed description of the preferred embodiments

According to a preferred embodiment, illustrated in Figures 1 to 5, the device (1) according to the invention consists of a handle (2), called additional, connected to a hollow handle (3) sliding vertically on a rod (4), a housing (5) for fixing connected to said handle (3) via an oval hole (6), a ring (7) for locking said handle (3) relative to said housing (5) and a support member (8) of said device (1) on a rolling luggage (9) or a shopping trolley (9) disposed at the end of said rod (4).

These elements are arranged and cooperate as follows: said box (5), openable, serves as a connection between a handle (12) of origin of a baggage (9) wheel and said handle (2) additional, which it is mounted on a handle (3) retractable on said rod (4) supported by the element (8) dedicated on said luggage (9). Said hollow handle (3) is preferably made of metal and has a cross section of oval or square shape so that it can slide, without being able to rotate, in said oval or square hole (6) made in said housing (5). ).

This housing (5), shown in particular in Figures 5 and 6, is formed by two identical hulls connected by two hinges (10a, 10b), and has, in addition to the oval hole (6), an orifice (11) for fixing said device (1) on the handle (12) of origin of a shopping cart (9). Said housing (5) is held in closed position by a flexible clip (13) located opposite said hinges (10a, 10b). When the original handle (12) of said carriage (9) has a cross section much smaller than the most common handles, it is possible to place a gear (14) in the hole (11) of attachment.

This reducer (14), shown in Figures 6 and 7, is preferably made of an elastomeric material and has internal reliefs contributing to the adhesion of said housing (5) with the handle (12) of said original carriage (9). Said reducer (14) is formed by two hollow half cylinders each having a longitudinal locking projection.

The orifices (6, 11), said oval (6) and attachment (11), are parallel and both extend longitudinally from one end to the other of said housing (5). The fixing orifice (11) is coated with a layer of an elastomeric material to ensure a good attachment of said housing (5) with the handle (12) of origin of said luggage (9).

The additional handle (2) is automatically lowered by gravity along its handle (3) and advantageously has freedom of placement during its use, allowing it to be held at an angle of approximately 90 ° with respect to its handle ( 3). The freedom of movement of said handle (2) additional to its handle (3) is provided by an axis (16).

In another embodiment, the orifice (6) may be of square section or any other shape. In this variant the lateral offset is provided by the handle (3) and more by the handle (2), which there may be a ball (2) or a T (2). The attachment of the handle (3) to the housing (5) is achieved by a thumbscrew transversely passing through said orifice (6) oval through a threaded hole and tightening said sleeve (3). According to a third embodiment, represented in FIGS. 9 to 11, more particularly intended for suitcases (9) with wheels having a handle (12) of retractable U-shaped inverted origin, the device (1) no longer has a case ( 5) but a rail (15), included during the manufacture of said bag (9), placed on one or other of the vertical branches of said (12) inverted U-shaped retractable handle, for extending said handle (3) of said additional handle (2). In this second variant, said additional handle (2) can be retracted into a horizontal housing, figurelO, or vertical, Figure 11, provided for this purpose in said bag (9). The handle (3) then has grooves interlocking in said rail (15) to ensure a durable maintenance and a possibility of sliding relative thereto.

According to a fourth embodiment, shown in FIGS. 12 and 13, the attachment device to the original handle consists of collars type collars (17) which encloses a half-casing (18) against the handle of origin of the cart. Everything is held firmly by means of needle screws (19). The detail of the device is shown in Figure 13. This device can also adapt to suitcases. In this case, said device is located at the rear of the handle to allow free access to the push button (20) triggering the height adjustment of the handle (12) of the original bag, and to retraction system of the handle. Figure 15 shows this device in section from side (left), and from above (right). The telescopic portion (20 and 21) may be of flattened section or semicircle, for less total thickness of the handle.

In Figure 14, the principle of telescopic handle (21) can, in the manufacture of shopping trolleys or suitcase, to be integrated inside the handle (12) original. This telescopic handle is composed of 3 main elements: the handle as a gripping means (2), a handle (3) as a rigid connecting means and a fastening means (5) inserted into the handle of the luggage (12). ) as a component of the wheeled container.

In an exemplary embodiment, the holding means (11) consists of clamps binding it to the oval hole (6) serving as connection means with the rigid connection means.

According to a fifth embodiment, shown in Figures 16 and 17, there is a housing (5) of two half-shells, said device comprises jaws (22) which strongly enclose the handle (12) of the original carriage . The rod (3) of the handle (2) said additional square or oval section, slides in the housing (5) of the device. The gripping means (2) is hollow and fits on the housing (5) when folded.

The non-substantial modifications which would clearly follow, for those skilled in the art, from the use or manufacture of the device according to the invention whose patent is here required without altering the original arrangements, would not be than simple technical equivalents and are also within the scope of the present invention.
