Description

DESCRIPTION

Street cleaning trolley

TECHNICAL SECTOR

The present invention refers to a street cleaning trolley, of the type that incorporates means for storing the waste collected from the road and for transporting it in a comfortable and simple way.

The object of the invention is to provide a light, practical and ergonomic trolley, with a structure such that it avoids injuries to the workers and makes their work easier while its maintenance is simple and cheap.

BACKGROUND OF THE INVENTION

In the field of practical application of the invention, trolleys are known in which a rolling frame participates, movable through a handle, a frame in which a platform participates on which a couple of tanks are integrated for the collection of waste , tanks on which the corresponding bags are usually placed previously, to facilitate the maneuver of emptying their content.

The problem with this type of trolley is that the tanks have a considerable height, so that the bags must be removed while saving the height of said tanks, which is a maneuver that requires considerable effort, which can cause back injuries.

In addition, these deposits significantly increase the weight of the trolley, which can also result in injuries to operators when pushing the trolley.

Finally, it is worth noting the fact that this type of trolley only incorporates two wheels arranged diametrically on the central area of the chassis, so that its maneuverability leaves much to be desired when avoiding obstacles such as steps, curbs or the like.

EXPLANATION OF THE INVENTION

The one advocated fully satisfactorily solves the aforementioned problem, based on a simple but effective solution.

For this, and more specifically, the trolley of the invention is constituted from a rolling frame, in which a rectangular platform participates, on whose sides and in correspondence with its longitudinal middle zone a pair of bicycle wheels are established. with a diameter of the order of 20 inches, which gives it good handling, thin wheels that have less friction which makes it very light when riding.

For its part, in correspondence with the front area of the frame, another pair of wheels will be included, with a smaller diameter, which facilitates maneuverability when climbing steps. These wheels also prevent the cart from stopping suddenly in the event of moving if the cart leans excessively forward, also avoiding possible injuries to the wrists, elbows and shoulders.

According to another of the characteristics of the invention, the platform will have a drawer in its central area that has two compartments, an upper compartment for the worker's personal effects and a lower compartment for bags, while replacing the classic tanks. waste collection, the platform will include a structure based on four vertical struts on which a horizontal frame is established, on which a pair of rings or hoops are collapsible, which will determine, in conjunction with the frame, the means of supporting the waste collection bags.

In this way, the weight of the trolley is significantly reduced, increasing its load capacity as the bag can expand.

On the other hand, not carrying buckets or tanks also makes a change from a full bag to an empty bag much less laborious and avoids unwanted injuries to workers by not having to remove the bag "freehand" from the bucket (it implies lifting said bag loaded above one meter in height).

In this case, it is enough to open the rings and the bags will be loose at the height of the ground.

From this structure, a car is obtained whose maintenance is very cheap, since all its components are very easy to find, in addition to using standard wheels.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that is going to be made below and with the aim of helping a better understanding of the characteristics of the invention, according to a preferred example of a practical embodiment thereof, a set of drawings is attached as an integral part of said description. where, with an illustrative and non-limiting nature, the following has been represented:

Figure 1.- Shows a perspective view of a street cleaning trolley made in accordance with the object of the present invention.

Figure 2.- Shows a side elevation view of the device of the previous figure.

Figure 3.- Shows a profile view of the carriage.

Figure 4.- Shows, finally, a plan view of the trolley of the invention.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the outlined figures, it can be seen how the trolley of the invention is constituted from a rolling frame (1), in which a rectangular platform (2) participates, on whose sides and in correspondence with its longitudinal middle zone a pair of larger wheels (3) are established, specifically 20-inch bicycle wheels, while which, in correspondence with its front end, includes a pair of smaller wheels (4).

The larger wheels (3) will be protected at the frame (1) by tubes (5) as bumpers.

The platform (2) defines the transport area for the waste collection bags, so that they will be supported in an upper frame (6), supported by four struts (7), stabilizing its mouth by means of folding rings or rings (8) on the frame itself (6).

The trolley will be propelled through a handle (9) that is linked to the two rear struts (7) of the frame (1), counting its platform in its central area with a drawer (10) that has two compartments, an upper compartment for worker's personal effects and a lower compartment for bags.

In this way and as mentioned previously, the bags rest on the platform (2) and stabilize on the folding rings (8), so that they can expand freely laterally, increasing the load capacity and greatly facilitating the maneuvers of withdrawal of the same.

In this way, a device that is maneuverable, light, ergonomic and easy to maintain is achieved.
