Description

The present invention relates to the technical field of handling, and transport or movement of garbage containers, generally carried out by road agents.

Prior art

The profession of road agent requires having to handle and move garbage containers, sometimes over great distances. Garbage containers can be large, for example they exist in capacities ranging from 120 L to 360 L. Trash containers generally include rollers and gripping means at one of their upper edges.

The rollers make it easier to move these containers, while the gripping means allow them to be grasped by a lifting / overturning mechanism that includes, for example, a garbage collection vehicle. The gripping means are in particular standardized (standard EN840), and are in the form of a folded rim which forms a groove open towards the bottom of this container.

Street workers are sometimes tasked to transport this type of container over long distances, for the purpose of garbage collection, or for collecting garbage bags. It follows that the modest wheels that this type of container presents make the task difficult and tedious.

Indeed, in general, the containers have wheels only at the rear, which forces the road operator to keep the container in a tilted position to move it. This is not satisfactory, and can lead to musculoskeletal problems on the part of the road agent.

-2 To solve this problem, it is known to use devices allowing the movement of waste collection bags. This type of device, commonly called road cart, has a rolling structure equipped with wheels and extended by a handlebar. The handlebars are extended horizontally by a hoop which receives a garbage bag for collecting waste.

This type of cart makes it easier for road workers to carry out rounds of waste collection.

However, the capacity of the waste collection bag on board this type of road cart is limited, and this solution does not make it possible to solve the problem of moving the standardized trash containers, which have large dimensions.

In addition, road carts are difficult to handle, are not ergonomic, and present some difficulties in overcoming certain urban obstacles, for example sidewalks.

Expose the invention

One of the aims of the invention is therefore to remedy the aforementioned drawbacks, in particular by providing a device for moving a trash container of the standardized type, which is ergonomic, handy, stable, and easy to use.

To this end, a device has been developed for moving a trash container of the standardized type, that is to say of the type comprising an upper rim folded downwards to form a groove open downwards. .

According to the invention, the device comprises:

- a rolling structure comprising at least one rear wheel, and two front wheels spaced from one another to receive the garbage container therebetween;

- a handlebar comprising two uprights connected to each other by a lower cross member, each upright comprises a hook disposed at its upper end capable of coming into engagement in the groove of the container, the handlebars being mounted so as to pivot relative to the rolling structure, between a substantially vertical approach position in which the hooks are intended to be positioned below the edge of the container, and a rolling position, pivoted rearward, in which the hooks are intended to lift the container by the edge up the container is no longer in contact with the ground and comes to bear against the lower cross member.

In this way, the device according to the invention makes it possible to lift any standardized container, in a simple and effective manner. In the handlebar rolling position, the operator can easily push or pull the rolling structure to move the container.

Preferably, in order to increase the ergonomics of use of the device according to the invention and to adapt perfectly to the size of the road agent, the handlebars include several successive rolling positions making it possible to successively lower the height of use of the handlebars with respect to the ground, as the handlebars pivot towards the rear.

Preferably, the handlebar includes an intermediate position, located between the approach position and the first rolling position, in which the container is intended to be lifted by the hooks, with the bottom of the container still in contact with the ground. This intermediate position makes it possible in particular to prevent the rolling structure from rolling, and thus immobilize the device. This position is assimilated to a so-called parking brake position.

Preferably, the handlebar comprises an extreme rolling position in which the lower crossbar of the handlebar abuts against a stop fixed on the rolling structure at the front wheels, the extreme position being intended to move the center of gravity of the container behind the front wheel center line to allow the handlebars to be used as a lever to lift the front wheels, in combination with the stopper.

In this way, it is easy for the road worker to raise the front wheels of the device, in particular for crossing obstacles such as sidewalks.

Advantageously, and to facilitate the use of the device, as well as its ergonomics, the latter comprises means for locking the various positions of the handlebars.

According to a particular embodiment, the locking means are in the form of an indexing finger fixed to the rolling structure, retractable by means of a cable actuable by a handle located on the handlebar, said finger d indexing being intended to be inserted, for each of the positions of the handlebars, into an orifice that includes a tab disposed at the level of the lower crossbar of the handlebars.

Advantageously, the rolling structure has two guide pads arranged opposite one another at the front wheels, and spaced apart by a width corresponding to the width of the container to be moved, in particular to guide its passage between the front wheels. .

Preferably, the device comprises means for braking the front wheels, for example independent for each of the wheels, actuable from the handlebars. Preferably, the rolling structure comprises at least one sleeve for receiving a handle of a tool, such as a shovel, a broom or the like. The fact that this sleeve is fixed to the structure allows it not to be pivoted at the same time as the handlebars.

Advantageously, the handlebars include an upper crosspiece connecting the two uprights, and supporting an empty storage compartment, making it possible to receive the personal effects of a roadworker, or else a work sheet.

Detailed Description of the Invention

With reference to FIGS. 1 to 10, the invention relates to a device (1) making it possible to facilitate the handling, movement and transport of a container (2) with trash cans of the standardized type, that is to say of the type comprising an upper edge (3) folded downwards to form a groove open downwards. This type of container (2) can have

-6 different sizes, that is to say different capacities ranging in particular from 120 L to 360 L for example.

To this end and with reference to Figures 1 to 7, the device (1) comprises a rolling structure (4) comprising at least two front wheels (5), and at least one rear wheel (6). Preferably, the structure comprises two rear wheels (6), of the idler wheel type, that is to say that they can pivot freely around a substantially vertical axis. The presence of two rear wheels (6) makes it possible to increase the stability of the device (1) and to be able to lift the front wheels (5) more easily by pressing on the rear wheels (6).

Referring to Figure 6, the rolling structure (4) is composed, for example, of a tubular frame on which are mounted the four wheels (5, 6). The two front wheels (5) are parallel to each other, aligned, and spaced apart by a width to receive the container (2) between them. The chassis comprises for example two tubular arms (7) on which the front wheels (5) are fixed, connected by a cross member (8). The arms (7) are extended inward by guide shoes (9) arranged opposite one another, at the front wheels (5). These two pads (9) are spaced by a width corresponding to the width of the container (2). For example, these two pads (9) can be threaded to adjust the distance between them and thus adapt to more or less wide containers (2). The two pads (9) are made of non-stick plastic to be able to slide efficiently on the walls of the container (2) during its guidance and reception between the two front wheels (5).

The device (1) according to the invention also comprises a handlebar (10) allowing an operator to handle and drive the device (1). The handlebar (10) comprises in particular two uprights (11) interconnected by a lower crosspiece (12). The handlebar (10) is pivotally connected to the rolling structure (4), around an axis (13) parallel to the lower crossmember (12), and located on the uprights (11), above the crossmember lower (12), and between the front (5) and rear (6) wheels of the rolling structure (4).

In this way, the handlebars (10) can be pivoted forward to approach a container (2) with garbage cans arranged between the front wheels (5), and rearward to

-7 move away from said container (2). The pivoting of the handlebars (10) also makes it possible to move the lower crossmember (12) of the handlebars (10), along a circular path.

The uprights (11) of the handlebars (10) each comprise a hook (14) disposed at its upper end, which is able to come into engagement in the groove of the container (2).

The handlebar (10) is able to pivot to adopt a plurality of positions, in particular a so-called approach position, see FIG. 2, substantially vertical, in which the hooks (14) are intended to be positioned below the rim (3). container (2) when it is located between the front wheels (5).

For example, the distance between the ground and the ends of the hooks (14) when the handlebar (10) is in the approach position is between 900 and 950 mm. Thus, for a 120 L container (2), the height of the hooks (14) will be 900 mm.

The pivoting towards the rear of the handlebar (10) makes it possible to adopt a so-called intermediate position, see FIG. 3, in which container (2) is intended to be lifted by the hooks (14) received inside the rim (3 ) until the container (2) comes to bear against the lower crossmember (12), while keeping the bottom of the container (2) in contact with the ground. This position makes it possible to initiate the lifting of the container (2), but does not allow the movement of the rolling structure (4). This position is assimilated to a parking position.

With reference to FIG. 4, the fact of tilting the handlebars (10) further back allows the handlebars (10) to adopt a first rolling position in which the container (2) is no longer in contact with the ground, and perhaps moved by manipulating the handlebars (10) and directing the rolling structure (4).

The handlebar (10) is handled like a handlebar (10) for a bicycle, and for this purpose comprises handles (15), and preferably levers (16) for the bicycle brake, each connected to brake shoes positioned so to grip the front wheels (5) and to perform braking by means of pads.

It is possible to have only one lever which would brake the two front wheels (5) at the same time. However, the fact that the brake levers (16) are independent makes it possible to independently brake a front wheel (5), and thus facilitate the making of a turn when the device (1) is moving. The brake levers (16) thus facilitate the use of the device (1), but also facilitate the pivoting of the handlebars (10) by blocking the front wheels (5).

Pivoting the handlebars (10) further back allows the handlebars (10) to adopt a second rolling position, in which the handlebars (10) are further lowered to adapt to the size of an operator smaller. Preferably, the handlebar (10) comprises several successive rolling positions, see FIG. 4, making it possible to successively lower the height of use of the handlebar (10) relative to the ground, as the pivoting towards the rear handlebar (10).

With reference to FIG. 5, the handlebar (10) also includes an extreme rolling position, pivoted as far back as possible and in abutment. In this position and with reference to FIGS. 7 and 10, d, the lower crosspiece (12) of the handlebar (10) abuts against a stop (17) fixed on the rolling structure (4) at the level of the front wheels (5). This extreme position lowers the height of the handlebar (10) as much as possible, and is also intended to move the center of gravity of the container (2) behind the axis of the front wheels (5). This position allows in particular an operator to be able to use the handlebars (10) as a lever arm to lift the front wheels (5), in combination with the stop (17), in order to be able to overcome obstacles such as sidewalks.

Referring to Figures 7 to 10, the device (1) comprises locking means (18) of the different positions of the handlebar (10). The locking means (18) are for example in the form of an indexing finger (19) mounted on a fixed part of the rolling structure (4), and connected to a cable to be retractable. The cable is connected to an operating handle (20) located on the handlebar (10). Advantageously, this actuating handle (20) is located at one of the handles (15) of the handlebar (10), to be operable with the operator's thumb or forefinger.

-9The lower crossbar (12) of the handlebar (10) comprises a protruding tab (21), orthogonal to said lower crossbar (12), and arcuate according to a radius of curvature whose center is the axis (13) of rotation of the handlebars (10). This tab (21) is perforated with a plurality of holes (22), in which the indexing finger (19) is intended to be inserted to successively block each of the different pivoting positions of the handlebar (10).

Figures 9 and 10 show in detail the locking positions of the approach position, see Figure 9, and the extreme position for lifting the front wheels (5), see Figure 10. The stop (17) against which is intended to abut the lower crossmember (12) of the handlebar (10) in the extreme position makes it possible to be able to lift the front wheels (5), without forcing on the indexing finger (19), and therefore without risking damaging it.

Preferably, sleeves (23) for receiving a handle of a tool, such as a shovel, a broom or the like, are fixed substantially vertically on the structure, for example on either side of the handlebar (10 ).

Advantageously, the two uprights (11) of the handlebars (10) are connected in the upper part by a cross member which makes it possible to receive and support, in a removable manner, a quickly pocket chest (24).

It follows from the above that the invention does indeed provide a device (1) for moving a container (2) with standard bins, which is ergonomic, stable, handy, and easy to use.
