Description

The present invention aims to provide an effective remedy to the

  handling purchases (or other) made by individuals and simplify the transport of said purchases, with a trolley that the user places in the trunk of a motor vehicle.

  The handling and transport of purchases are currently and traditionally carried out using a trolley made available to the customer, and this exclusively in the area of commercial surfaces.

  In addition, this truck, given its depth, requires the customer to look at each item purchased.

  On an example of 25 items purchased, the customer is obliged to handle and transport his purchases under the following conditions: From the store shelf to the bottom of the cart (25 times), from the bottom of the cart to the treadmill of the box (25 times ), after scanning and put in plastic bags of the purchased products (more or less 10 times), the trunk of the car at home (more or less 10 times), storage in the kitchen (at least 25 times), a total of manipulations.

  The device according to the invention overcomes these disadvantages.

  The invention relates to a basket trolley (1) intended to be introduced with its contents, by its user, into the trunk of a motor vehicle characterized by a single central foot (4) locked in its center and removable after having been unlocked. .

  According to particular embodiments: - the single central foot (4) is held by a base (18) consisting of a plurality of X-shaped branches, cross or star whose ends are equipped with multidirectional wheels (3).

  - The base (18) has a wheelbase commensurate with the size of the basket (1), or larger dimension than the base of the basket (1), allowing perfect stability of the latter on the foot (4) after locking.

  - The foot (4) separates, if necessary, the base (18), after unlocking for easier storage in said trunk.

  - The foot (4) is held in the center of the basket (1) by a threaded tube at its base (11) and on its upper part (10). This tube (10 and 11) is surmounted by a round plate (9) and a handle (8). All of this device allowing the manual locking and unlocking of the basket (1) of the central foot (4) will be protected by a cylindrical casing (7), in order to make said tube accessible to the user when the basket ( 1) is full (Figures 4, 5 and 6).

  - The round plate (9) surmounted by a handle (8) is pressed inside, in the center and on the bottom of the basket (1), thus ensuring the stability of the basket (1) with the foot (4) when these last two are locked together.

  - the single foot (4) is welded to a frame (16) provided at each corner of a wheel (17) or a plurality of rollers (17); the assembly rolls, after unlocking, in the guide (13) located under the basket (1) towards the rear, as the basket (1) is introduced into the trunk of a motor vehicle, without rolling or pitch (Figures 3, 4, 7 and 10) - a buffer (14) allows the opening of the central foot (4) to be positioned opposite the other central orifice (12) located in the bottom (15) of the basket (1) to be locked.

  - A multidirectional wheel is positioned at each corner under the basket (1) to roll it in the trunk of a motor vehicle and place it in the desired location (left, right or middle).

  - the casters (3) located under the basket (1) are manually adjusted, if necessary, upwards or downwards to allow them to be positioned at the trunk of a motor vehicle, before the introduction of the basket ( 1) in said box.

  The basket of the carriage has indeed according to a first feature, a single foot that is manually locked or unlocked in the center, for introduction into a trunk of a motor vehicle or extracted from it.

  The objectives and remedies above will appear in the following description and in the accompanying drawings which illustrate the invention: Figure 1 shows the carriage viewed from the side, in perspective.

  Figure 10 shows the side view of the cart whose foot has been unlocked from the basket, thus allowing said basket to enter more into the trunk, while being maintained horizontally through the guild. Thus the basket is not subjected to rolling or pitching.

  Figure 11 shows a side view of the basket in the trunk and the foot which is fully released from said basket.

  Figure 12 shows a side view of the basket in the trunk with its side with its foot and its base unlocked.

  Referring to the drawings to describe a non-limiting embodiment of a carriage consists of a basket with central single foot that locks or unlocks.

  The carriage consists of 4 removable parts, namely: a basket (1), a foot (4), a base (18), a tube (10 11).

  a) a basket (1) containing the purchases.

  b) A central tubular leg (4) which locks or unlocks at the base on a base (18). 4 2880606 c) This base (18) consists of a plurality of X-shaped, cross or star-shaped branches whose ends are equipped with multidirectional wheels (5).

  The wheelbase of the base (18) is proportional to the size of the basket (1), or larger than the base of the basket (1).

  d) A threaded tube at its base (11) as well as on its upper part (10).

  This tube (10 -11) is surmounted by a round plate (9) and a handle (8).

  To enable the carriage to be steered, a handle (2) is attached to the back of the basket (1).

  The assembly of the tubular foot (4) with the basket (1) is carried out manually using the threaded tube (10 11) surmounted by a round plate (9) and a handle (8). provided by a first thread (6) located inside the tubular foot (4) and by a second thread (12) located at the center of the basket (1), inside and in the bottom (15) of said basket ( 1).

  The round plate (9) is then plated inside and at the base of the basket (1), thus ensuring the stability of the basket on the foot (4).

  The threaded tube (10 11) surmounted by the round plate (9) and the handle (8) which makes it possible to lock or unlock the basket (1) will be protected by a cylindrical casing (7), in order to make said tube accessible to the user when the basket is full.

  On the upper part of the central foot (4) is welded a frame (16) provided at each corner of a fixed wheel (17).

  The guide (13) fixed under the basket (1) allows to receive the frame (16), the introduction of which is from the rear of the carriage.

  Thus the hole of the foot (4) will be directed towards the center of the basket (1) in a rectilinear manner.

  A stop (14) will allow the opening of the foot (4) to be positioned opposite the other central opening (12) located in the bottom (15) of the basket (1).

  This set will allow the foot (4) when unlocked to roll backward as the introduction of the basket (1) in the trunk, and without rolling or pitching.

  Under the basket and at each corner, a multidirectional wheel (3) is fixed to allow said basket to roll in the trunk of the car and place it at the desired location (left, right or center).

  These rollers (3) are manually adjusted, if necessary, upwards or downwards to allow to position them at the trunk level, before the introduction of the basket (1) in said trunk.

  The foot (4) separates if necessary from the base (18) for easier storage in the trunk.
