Description

Field of the art

[0001] The invention relates to an innovative system for transporting rubble deriving from construction works, employing a cage apt to lift and move a common approved bucket, placing it on a plinth where any worker is apt to comfortably manage the manual handling thereof.Prior art

[0002] Workers employed in construction sites today face numerous problems related to lifting weights and handling rubble, with significant consequences for their health and safety.

[0003] The main problems include musculoskeletal injuries, caused by incorrect postures, repetitive movements and the lifting of heavy loads without adequate aids. Such injuries can manifest in the form of muscle tears, herniated discs, tendonitis and other related pathologies.

[0004] A further significant risk is represented by falls and slips. Moving heavy materials, often on uneven or wet terrain, increases the likelihood of accidents that can result in serious injuries such as fractures, bruises and head trauma. Handling rubble also involves exposure to dust and harmful chemicals, with potential damage to respiratory health, such as bronchitis, asthma and, in the long term, occupational diseases such as silicosis.

[0005] Physical overload and stress resulting from the need to meet tight deadlines represent further sources of risk. Lifting heavy loads contributes to excessive physical fatigue, increasing the likelihood of mistakes and accidents at work.

[0006] Nowadays, the use of inadequate or obsolete equipment aggravates the situation, often forcing workers to perform dangerous manual operations. Furthermore, insufficient training on correct lifting methods and safety practices negatively affects risk awareness and safe behaviours. Work environments are not always designed while taking into account ergonomic needs, leading to incorrect postures when lifting and moving materials, with a consequent increase in the risk of injury.

[0007] To mitigate these problems, it is essential to adopt a series of preventive measures, which include the adoption of state-of-the-art means and systems, in order to safeguard the health of workers.

[0008] Instead, workers are currently obliged to move the rubble deriving from construction works using approved buckets which, however, are characterised by considerable weights. The mere lifting of one of these buckets from the ground can be harmful to the health of the operator concerned.

[0009] To date, unfortunately, there are no known systems that simplify the handling and lifting of buckets full of debris and rubble; each worker is also obliged to handle dozens of them per day.

[0010] Even patent MX2022015559, published on 9 June 2023, does not solve the above problems, as it claims a bucket handling system without, however, envisaging any suspension, but only a single dragging device, which therefore does not solve the problems related to construction sites.

[0011] Therefore, the object of the patent is to propose a system for lifting and moving rubble, which is apt to deliver a common bucket to the worker, who will be able to handle it starting from a privileged position, at a height of at least one metre above the ground, minimising the stresses due to back bends.Description of the invention

[0012] According to the present invention, a construction rubble transport system is created which effectively solves the aforementioned problems.

[0013] The construction rubble transport system which is the subject of the invention represents an efficient and practical solution for handling rubble within any construction site. Thanks to the containment cage, the stable plinth and the various structural devices, the present system is apt to facilitate the work of workmen, reducing the risk of injury and improving the efficiency of movement operations.

[0014] The construction rubble transport system described in the present patent application is designed to facilitate moving the rubble produced during construction and renovation activities. This system therefore makes use of a containment cage which allows a generic approved bucket, contained therein, to be moved vertically.

[0015] When the bucket is filled with rubble, it can be lifted and moved inside the cage through a common pulley system, until it reaches a plinth designed to hold the cage itself.

[0016] Said plinth consists of a plurality of legs that facilitate the sliding and interlocking of the cage, leaving the bucket full of rubble permanently leaning on the heads of the aforementioned legs, allowing workmen to pick it up from a comfortable and safe height.

[0017] Such a containment cage is therefore apt to hold any approved bucket intended for the movement of construction rubble. Its structure consists of a sturdy skeleton which encloses the bucket but at the same time allows the cage to slide easily inside the legs of the plinth. A fundamental element of the cage is the handle, which is connected to the upper circumference of the cage by means of common hinges. This handle allows the cage to be lifted and moved using a generic pulley system. Furthermore, said handle is designed to rotate and align with the upper circumference of the cage, thus facilitating the removal of the bucket once it has reached its destination.

[0018] In an embodiment thereof, the upper circumference of said containment cage is apt to be adjusted in width, thanks to a telescopic mechanism comprising snap buttons for fixing the diameter of the chosen circumference.

[0019] By way of non-limiting example, the skeleton of which the containment cage is composed, is made of composite material, in order to minimise weights, while maintaining a high load strength. Alternatively, said skeleton is made of metallic material, apt to be welded in order to minimise the movements and bending of the cage during the handling of rubble. In a further embodiment thereof, the skeleton is composed of a plurality of metal pieces, apt to be reversibly bolted together, making said cage dismountable and easily movable from one construction site to another.

[0020] The plinth on which the cage rests plays a crucial role in the system which is the subject of the invention. It consists of a plurality of legs which are apt to engage in the skeleton of the cage, allowing it to slide exclusively downwards. This movement is apt to free the aforementioned bucket, which remains leaning stably on the legs of the plinth.

[0021] The design of the plinth includes a perimeter reinforcing structure, which ensures that the legs remain equidistant from each other, and an internal reinforcing structure in the shape of a cross, which joins the diametrically opposed legs. This configuration serves to limit any bending of the plinth, ensuring greater stability and safety during the bucket storage operation.

[0022] By way of non-limiting example, rubberised heads are apt to be installed above each leg of the plinth, in order to cushion the contact of the bucket with the plinth, reducing the impact and preventing any damage. Furthermore, said rubberised heads are apt to increase the stability of the bucket when it is deposited on the aforementioned legs. Finally, to ensure greater stability of the plinth, even on uneven terrain, each leg is provided with feet, which allow the plinth to adapt to different surfaces, always maintaining a stable, safe and flat position.

[0023] By way of non-limiting example, said feet comprise a screw terminal apt to allow the engagement of said plinth within any uneven terrain, increasing the stability of the entire construction rubble transport system.

[0024] In an embodiment thereof, said feet are perforated in such a way that they can be fixed to the ground, in order to fix the entire plinth, reducing any unbalancing risk of the bucket.

[0025] The advantages offered by the present invention are apparent in the light of the description set forth herein and will be further clarified by the accompanying figures and the detailed description.Description of the figures

[0026] The invention will be described below in at least one preferred embodiment by way of non-limiting example and with the aid of the accompanying figures, in which: FIGURE 1 shows, in a simplified diagram, the operation of the system described in the present patent application, showing how a bucket 20 contained inside the cage is apt to be moved vertically until being leaned on the rubberised heads 12 of said legs 13 belonging to the plinth. FIGURE 2 shows the perspective view of the construction rubble transport system which is the subject of the invention, in particular how said cage is apt to engage between the legs 13 of said plinth. Detailed description of the invention

[0027] The present invention will now be illustrated by way of non-limiting or binding example, using the figures which illustrate some embodiments in relation to the present inventive concept.

[0028] With reference to FIG.1, the operation of the system described in the present patent application is illustrated, in order to show how the bucket 20, initially contained in the cage, is apt to lean on said rubberised heads 12, freeing itself from the cage which is instead apt to slide by means of its skeleton 15 between the legs 13 of the plinth.

[0029] The bucket 20 is then suspended and moved by a common pulley system which is apt to be constrained on a handle 11 in turn constrained to the circumference 10 of the cage by means of two hinges 14.

[0030] In order to be able to hold buckets 20 of different sizes, said circumference 10 is apt to be modified, thanks to a telescopic mechanism.

[0031] The legs 13 of the plinth are able to remain in position, offering a stable support to the bucket 20, thanks to the use of a perimeter reinforcing structure, apt to hold said legs 13 together and equidistant, limiting any bending due to the compression caused by the bucket 20, once leaned.

[0032] The feet 16 allow an advantageous increase in stability on the irregular surfaces typically characterising construction sites.

[0033] With reference to FIG.2, a perspective view is illustrated which is apt to highlight how the cage and the plinth belonging to the present rubble transport system are apt to interlock with each other, releasing the approved bucket 20 moved inside the cage, after being suspended between the floors of any building undergoing restoration.

[0034] Said cage comprises a skeleton 15 apt to contain the bucket 20 but at the same time apt to engage between the plurality of legs 13 that make up the plinth of the system which is the subject of the invention.

[0035] Said legs 13 have on their upper end a rubberised head 12, apt to stabilise and support the weight of the bucket 20 when it is released from the cage. Each leg 13 further has at least one foot 16, which can be anchored to the ground in order to make the present system usable even on uneven ground.

[0036] The skeleton 15 of the aforementioned cage is instead constrained to a circumference 10 of the cage, which, in an embodiment thereof, is extendable and retractable.

[0037] Two hinges 14 are installed on said circumference 10 which have the purpose of allowing the engagement of a handle 11, useful to facilitate the coupling of the cage to a generic lifting system, allowing the lifting and movement of the rubble deriving from construction works.

[0038] Lastly, it is clear that the invention described up to now can be subjected to modifications, additions or variants obvious to those skilled in the art, without departing from the scope of protection outlined by the attached claims.
