Description
Technical Field
The present invention relates to an outdoor furnishing element (outdoor furniture element) and a manufacturing process thereof. The outdoor furnishing element of the invention is preferably, but not exclusively, used as a city furnishing element, which may simultaneously be used as a vehicle traffic restriction (traffic destination) or delimiting element.
Background
Outdoor facilities are a wide range of product categories, generally comprising furnishing elements intended for private or public outdoor spaces, such as, for example, benches, tables, flower pots (planters), waste containers, billboards or support elements for headlines, information or advertising panels, etc. Such furnishing elements are made in various shapes and in various materials, for example metal, plastic, wood, stone, concrete or combinations thereof, according to functional and/or aesthetic requirements.
In public environments, it is also often desirable to prevent vehicles from entering or stopping in a given area, i.e., it is often desirable to protect pedestrians, buildings, or structures from accidental or intentional vehicle collisions. To this end, special fixed or movable/removable vehicle traffic-arresting or delimiting elements may be used, such as metal rods, concrete or stones, so-called "Jersey" guardrails, etc. Alternatively, the use of urban furnishing elements as traffic deterrents is also known, for example flowerpots or benches with appropriate structural features (weight, robustness, etc.) to perform such functions.
Today, outdoor furnishing elements as traffic-stopping elements are usually manufactured in batches by various conventional processes selected according to the type of element to be manufactured and the material used.
Usually, the manufacturer provides a certain number of models for each type of outdoor furnishing element or traffic deterrent element, which models have different structural, functional and/or aesthetic characteristics, but are in any case defined in advance by the manufacturer itself. There is little or no possibility of customizing outdoor furnishing elements or traffic-stopping elements currently available on the market to meet the needs of a particular user, particularly in terms of aesthetics, such as shape and exterior finish (finish).
This is a limitation of known outdoor furnishing elements or traffic deterrent elements, as there are a variety of environmental contexts in which they can be used, and it is not always possible to obtain a product that is best suited to a particular environmental context, depending on the user's requirements.
Another drawback of furnishing elements of the known type is that they are difficult to carry. In most cases, the placement, handling and removal of furnishing elements requires the use of lifting devices (cranes), for example platform cranes or mobile lift trucks (forklifts). This is critical in terms of cost and furnishing element management.
Summary of The Invention
The main task of the present invention is to provide an outdoor furnishing element which is capable of overcoming the above mentioned drawbacks. An object within the scope of the task is to provide a furnishing element which can be easily placed, handled and removed without the use of complicated lifting devices.
Another object is to provide a furnishing element whose external configuration can be defined individually for each individual element produced and which can be manufactured industrially in a simple and affordable manner in any case with the same process.
Another object of the invention is to provide an outdoor furnishing element of the aforementioned type, which is also suitable for use as a vehicle traffic stopping or delimiting element.
According to the present invention, these objects are achieved by an outdoor furnishing element having the features set out in the appended claim 1. Preferred aspects of such an outdoor furnishing element are the object of the respective dependent claims.
Accordingly, in its first aspect, the present invention relates to an outdoor furnishing element comprising a substrate for resting the outdoor furnishing element on a surface and a solid structure (solid structure) carried by and defined at the bottom by said substrate. According to the invention, the furnishing element comprises a passive handling system (passive handling system) mounted in the base plate or in a frame removably associated with the base plate. The transport system includes a plurality of casters and a locking device that inhibits or permits rotation of the casters to inhibit or permit transport of the display elements.
The prearrangement of the passive handling system allows direct, manual handling of particularly heavy outdoor furnishing elements, such as for example benches or pots, for example to temporarily remove them from usual positions or to arrange them in the environment, without the need for auxiliary devices, such as lift trucks or mobile cranes, the use of which would lead to an increased economic and logistical burden and also to the waiting times required for the intervention of the auxiliary devices.
The possibility of handling the outdoor furnishing element of the invention without using auxiliary devices is particularly advantageous when it is used as a traffic-stopping element, in particular in all cases where it is necessary to provide more or less frequent temporary movements of the traffic-stopping element to allow the vehicle to enter into an area where traffic was otherwise prohibited.
In this respect, it is worth noting that, particularly in the urban public sector, it is generally necessary to ensure the possibility of relatively rapid entry in emergency situations and in areas where the passage of vehicles is prohibited, for example to take emergency countermeasures or law enforcement measures. Thus, when such areas are bounded by fixed urban furnishing elements and/or traffic deterrent elements, it is now common to create an entry point in which passage of vehicles is only impeded, rather than completely prohibited, for example by arranging the fixed urban furnishing elements and/or traffic deterrent elements in a staggered manner to create a tortuous path (meandering path) between them. However, law enforcement often attends to these entry points to ensure that they are not used by unauthorized vehicles. Alternatively, it is known to use folding traffic-deterrent elements in these situations, which are generally less robust than heavy-duty fixed traffic-deterrent elements and/or city furnishing elements or telescopic traffic-deterrent elements, which are significantly more costly to install and maintain than fixed traffic-deterrent elements and/or city furnishing elements.
In these cases, the outdoor furnishing element of the invention provided with a passive handling system advantageously allows to create heavy obstacles that completely prohibit the passage of vehicles in an affordable way, thus not requiring law enforcement watch, whereas in case of emergency temporary entry points can be created easily and quickly.
The locking device may preferably be controlled by a mechanical, electromechanical or electronic security key. Thus, it may be advantageous to allow only authorized personnel, such as law enforcement personnel, emergency personnel or residents in traffic-prohibited areas, who possess the security key to carry outdoor furnishings and traffic-deterrent elements.
Preferably, the locking device may be controlled by a mechanical, electromechanical or electronic security key. Thus, only authorized personnel equipped with security keys (e.g., law enforcement, rescue, or citizens living near the vehicle's transportation area) are allowed to move outdoor furnishings and block transportation elements.
In a preferred embodiment, the locking device of the handling apparatus can be controlled by means of an electronic code key, preferably a key fob.
In particular, in such embodiments a locking device may be provided, which comprises a wireless receiver that can receive control signals generated and transmitted by a suitable electronic user device, possibly after having transmitted a control code known only to authorized persons into the electronic user device. The technical solution particularly preferred here provides for the use
The receiver acts as a wireless receiver in the locking device and a smartphone or other suitable dedicated device is used as the electronic user device. Alternatively, RFID-based technical solutions may be considered.
It is convenient to select an electronic user device for controlling the locking device of the handling system, in particular when an outdoor furnishing element is to be used as traffic-stopping element, which is not only capable of generating and transmitting control signals for the locking device, but also of performing additional handling monitoring and/or user authorization management functions (such as, for example, recording data relating to the moment at which a user sends a lock/release command, sending such data to a command center at preset time intervals or in real time, setting the duration of the release state of the locking device, enabling/disabling the user on said electronic user device). These functions may be implemented in the electronic user device by specific software (e.g., a smartphone application).
As such, the outdoor furnishing element of the invention may not only serve as a movable deterrent element for creating a temporary passage in a traffic deterrent barrier, but may also serve as a system for automatically monitoring and managing the passage through such a barrier.
According to a possible embodiment, the locking device of the furnishing element comprises a first operating element, which rotates integrally with one or more of said castors, and a second operating element, which assumes a neutral configuration and an active configuration. The neutral configuration is such that the first operating element is free to rotate in a manner integral with the wheel; in the active configuration, the second element locks the rotation of the first operating element and therefore of the one or more castors rotating integrally with the operating element. The locking device further comprises switching means for switching the position of said second operating element between said neutral position and said active position.
According to a possible embodiment, the structure of the furnishing element comprises a relatively light shaped casing and a solid core (solid core) heavier than the casing, substantially filling a cavity of the outdoor furnishing element defined by the casing and the base plate.
Within the scope of the present description and of the subsequent claims, the term "substantially filled" referred to with respect to the solid core and to the cavity delimited by the casing and the substrate means that the solid core occupies the entire volume of the cavity, with fewer gaps naturally occurring due to possible non-uniform/granular nature of the material forming the solid core.
The component that integrates the product design into the outdoor furnishing element (i.e. the outer shell) and the component for the basic structural function (i.e. the inner solid core and the base plate) are structurally separate and can be manufactured independently of each other and have the features that are most suitable for the respective function.
The outer shell can advantageously be made of production materials and processes, which make it possible to "personalize" the outer shell on the basis of the individual requirements and user specifications relating to the shape and the external finish of the outdoor furnishing element, without this constituting a restriction on the configuration of the structural component. Vice versa, the internal solid core and the base plate can be configured and manufactured in a more convenient manner to give the outdoor furnishing element the most suitable structural features in relation to its type and function, substantially independently of the specific desired appearance of the outdoor furnishing element.
In particular, the structure of the outdoor furnishing element of the invention also allows to easily obtain an outdoor furnishing element usable as a vehicle traffic stopping or delimiting element. In fact, the structural components of the outdoor furnishing element, in particular the internal solid core made of heavier material, may be structured and dimensioned so as to impart to the outdoor furnishing element itself a weight and a solidity compatible with the traffic-stopping function, irrespective of the specific external shape and finishing of the casing.
The housing is preferably made of a plastic material. Such materials allow for easy and affordable manufacture of relatively lightweight housings of widely varying shapes by conventional subtractive or additive processing. Furthermore, if the outdoor furnishing element of the invention is also used as a traffic-stopping element, the casing made of plastic material advantageously allows to at least partially cushion the impact in case of a vehicle collision, to protect the integrity of the outdoor furnishing element itself and of the colliding vehicle.
One particularly preferred plastic material for the housing is polystyrene foam (EPS) because of its ease of molding, durability, and low cost.
The housing preferably has a monolithic structure to avoid bonding areas that may impair and/or impair its aesthetics.
The casing may have locally different thicknesses along its extension, which may vary from a few millimetres to a few tens of centimetres, according to aesthetic and structural requirements and to the type of material and manufacturing process used to make it. For example, in the case where the casing is made of polystyrene foam, the thickness may preferably be comprised between 20mm and 400mm, more preferably between 30mm and 200 mm.
In order to improve the mechanical characteristics of the casing, in particular if it is made of a relatively soft material, and in order to protect it from weather elements, it may be convenient to cover its exterior with at least one resin layer, preferably a polyurethane resin with increased mechanical resistance. Such a resin layer may have a thickness of a few millimeters, for example about 3 mm.
Reinforcing fibers (e.g., glass fibers, carbon fibers, aramid fibers) may also be incorporated in the resin layer.
The resin layer may also conveniently extend over the substrate or part thereof. This allows the substrate to be structurally bonded to the casing in a direct and independent manner, facilitating the formation of the cavity for housing the solid core during the manufacturing step of the outdoor furnishing element, and facilitating the structural articulation of the outdoor furnishing element.
Various types of finishes, such as a gel finish, grit, paint, and/or adhesive film, may be applied to the outer surface of the shell (i.e., on the resin layer, if present).
The solid core is preferably made of an at least temporarily pourable material. This advantageously allows the solid core to be brought into direct contact with the casing by filling the cavity of the outdoor furnishing element defined by the casing itself and the substrate with a pourable material, and then possibly curing it.
In a preferred embodiment of the outdoor furnishing element of the invention, the solid core also has a monolithic structure.
The solid core is preferably surface adhered to the shell so as to be integral therewith.
The solid core is preferably made of cementitious material (cementious material). This material advantageously combines processability and pourability in the fluid step, mechanical characteristics after curing and specific gravity, which are suitable for obtaining the required heavy structural parts when the outdoor furnishing element is used as a traffic stopping element, and which are low cost.
A particularly preferred cementitious material for making solid cores is aerated concrete (aerated concrete) due to the optimum fluidity during the casting step, the ability to adhere to the shell and the specific gravity characteristics once cured.
In alternative embodiments, the solid core may also be formed from a non-stick material, such as sand, gravel, or other suitable solid castable material.
The solid core may have a volume comprised between about 10% and about 50%, preferably about 20% to about 40%, of the total volume of the outdoor furnishing element.
The cavity delimited by the casing and the base plate and filled by the solid core is preferably a closed cavity, and the casing comprises an opening communicating with this cavity (preferably in a top position) to allow the introduction therein of an at least temporarily pourable material intended to form the solid core.
The substrate preferably comprises at least one portion incorporated in the solid core to improve the anchoring of the substrate to the solid core.
The portion of the substrate incorporated in the solid core may consist of a specific structure, for example an assembly of conveniently arranged grid or elongated and/or plate-like elements protruding from the inner face of the substrate, or simply of raised portions (covex ports) corresponding to the inner face of the functional cavity formed in the outer face of the substrate.

Detailed description of the preferred embodiments of the invention
Fig. 1 to 6 show a preferred embodiment of an outdoor furnishing element according to the invention, indicated as a whole with the numeral 100. The furnishing element 100 shown is in particular a city furnishing element, which can be used as a vehicle restraining or delimiting element.
Here, the outdoor furnishing element 100 typically has a total weight comprised between about 300kg and about 1800 kg. The average specific gravity (specific gravity weight) is preferably comprised in about 300kg/m3And about 1200kg/m3More preferably between about 500kg/m3And about 900kg/m3In the meantime.
The following description applies in any case also to other types and/or intended uses of the outdoor furnishing element 100, such as for example benches or any seats, tables or any resting surfaces, flower pots, supporting elements for various types of structures (information or advertising boards, lighting, sun-shading devices, etc.), waste containers or also items purely with a decorative function.
As shown in particular in fig. 1, the outdoor furnishing element 100 comprises a solid structure 1, 2 and a substrate 3 carrying and defining the solid structure. The term "solid structure" refers to a body formed in a single piece or in several pieces, having a basic structural function, i.e. capable of giving the furnishing element sufficient weight and volume to perform its intended function. Thus, depending on the application, one skilled in the art will be able to define the weight and volume characterizing a solid structure.
According to the invention, the furnishing element 100 comprises a passive handling system 5, 15 mounted on the base plate 3 or on the frame 4, the frame 4 being removably associated with the base plate 3. The transport system 5, 15 comprises a plurality of casters or wheels 50, 150 and a locking device which inhibits or allows the rotation of the wheels and thus the transport of the furnishing element 100.
According to a possible embodiment, the solid structure is made of concrete, even more preferably by a 3D concrete print process.
According to another embodiment, the solid structure comprises a shell 1 and a solid core 2. The housing 1 is preferably formed of a formed unitary body. The housing 1 is relatively light and made of a plastic material, preferably polystyrene foam (EPS). The casing 1 has a thickness preferably comprised between 20mm and 400mm, more preferably between 30mm and 200 mm. The thickness of the housing 1 may also vary locally.
The shape of the casing 1 can be freely selected according to the type of furnishing element and also according to the specific requirements of the individual user within the given type, in a manner substantially independent of the remaining structure of the outdoor furnishing element 100. In particular, the outer surface of the casing 1 (depicted in the figures as a generic, purely illustrative shape) may be formed by a single continuous curvilinear surface or by a plurality of curvilinear or flat surfaces joined at the corners, and may have hollow or protruding portions according to the functional and/or aesthetic requirements of the outdoor furnishing element 100.
In any case, the casing 1 comprises at least one hollow portion adapted to define, together with the base plate 3, a cavity 10 for housing the solid core 2.
The cavity 10 defined by the housing 1 and the base plate 3 is preferably a closed cavity. Here, the casing 1 comprises (preferably in a top position) an opening 11 communicating with the cavity 10 to allow the introduction into the cavity 10 itself of an at least temporarily pourable material intended to form the solid core 2, as described in more detail later with reference to the manufacturing process of the outdoor furnishing element 100.
The solid core 2 is generally the heaviest structural part of the outdoor furnishing element 100 and imparts the required robustness, stability and inertia characteristics to the outdoor furnishing element 100. In particular, the solid core 2 is heavier than the casing 1.
The solid core 2 is preferably made of a solid or settable material that is at least temporarily pourable.
In the preferred embodiment specifically illustrated herein, the solid core 2 has a monolithic structure and is made of cementitious material (preferably aerated concrete).
In an alternative embodiment, the solid core 2 may also be formed of a non-stick material, such as, for example, sand, gravel or other suitable solid castable material.
In any case, the external shape and dimensions of the solid core 2 are determined by the shape and dimensions of the cavity 10, in particular independently of the external shape of the rest of the casing 1. By way of example only, fig. 1 schematically depicts the solid core 2 as a parallelepiped.
The solid core 2 preferably occupies a volume comprised between about 10% and about 50% (more preferably between about 20% and about 40%) of the total volume of the outdoor furnishing element 100.
The base plate 3 is preferably made as a metallic structural element (for example steel) and serves to close the bottom of the recessed portion of the casing 1 intended to house the solid core 2 and the solid base delimiting the outdoor furnishing element 100.
In the embodiment shown in fig. 1 to 6, the base plate 3 comprises a plate 30, which plate 30, on the face facing the cavity 10, is provided with a structure intended to be incorporated in the solid core 2. As shown in fig. 1, this structure is formed in particular by a pair of profiled elements 31, the profiled elements 31 extending perpendicularly from the plate 30 and being interconnected at respective distal ends by transverse connecting elements 32, preferably floor-like elements. The shaped element 31 is preferably hollow and communicates with the external face of the plate 30 through a respective opening 33 made in the plate 30 itself. The base plate 3 may also advantageously comprise hooking portions or elements (not shown) for hooking the external lifting means.
The housing 1 is externally covered by a resin layer (not shown), particularly a urethane resin having an increased mechanical resistance. Such a resin layer helps to improve the mechanical characteristics of the surface of the housing 1, in particular the impact resistance, scratch resistance and abrasion resistance, if desired, and also helps to protect the housing from weather elements. Furthermore, the resin layer may serve to make the surface of the housing 1 more uniform for the continuous application of further finishing.
Reinforcing fibers (such as, for example, glass fibers, carbon fibers, aramid fibers) may also be incorporated in the resin layer.
The at least one resin layer preferably extends to cover the substrate 3 completely or partially. Thus, the substrate 3 is structurally bonded directly to the housing 1 (i.e., may be bonded to the housing 1 when the solid core 2 is not yet in the cavity 10). Alternatively or additionally, the substrate 3 may be fastened directly to the housing by glue or other suitable fastening means.
Various types of finishes (not shown) may be ultimately applied to the at least one resin layer (e.g., a gelled finish, grit, paint, and/or adhesive film).
As mentioned above, according to the invention, the outdoor furnishing element 100 comprises a passive handling system 5, 15, which has no own drive means. The handling system 5, 15 allows the outdoor furnishing element 100 to be handled directly by hand on the respective rest surface, also when it has an increased weight, for example to remove it from a given position or to arrange it in the environment. The passive handling system 5 is particularly useful for quickly handling outdoor furnishing elements 100 used as traffic-stopping elements without the need to use special handling devices when it is necessary to temporarily open a passage in a traffic-stopping barrier formed by such one or more elements to allow an authorised vehicle to enter a given area.
Again according to the above, the handling system 5, 15 comprises casters 50 (in particular here four casters 50, arranged in pairs) and a locking device by means of which the rotation of the casters 50, and therefore the operation of the handling system 5, can be inhibited or allowed.
In the embodiment shown in fig. 1 to 6, the handling system 5 is in particular mounted in a frame 4, which frame 4 is removably associated with the substrate 3.
As shown in particular in fig. 1, according to a possible embodiment, the frame 4 is formed by a plurality of shaped elements mutually assembled to form a flat base portion 40 and a pair of further shaped elements 41, the shaped elements 41 extending perpendicularly from the base portion 40 and being intended to be inserted through the opening 33, preferably by form coupling, into the hollow shaped elements 31 of the baseplate 3.
Certain profiled elements of the base portion 40, such as for example the transverse profiled elements 42, may be open towards the lower face of the base portion 40, so as to accommodate a rubber cushion (not shown) that increases the friction of the outdoor furnishing element 100 on the respective rest surface, which is a particularly advantageous feature when the outdoor furnishing element 100 is used as a traffic deterrent element.
The casters 150 of the handling system 5 are additionally rotatably fitted in the base part 40. The caster 150 is received in the base portion 40 so as not to protrude above the generally planar lower face of the base portion 40 or at most flush with respect to the generally planar lower face of the base portion 40. The first pair of casters 50 is fitted in particular at the articulated element 43 of the base portion 40, which articulated element 43 here also constitutes a locking device of the handling system 5. A second pair of castors 50 is mounted on the opposite side of the base portion 40 to the side comprising the hinge element 43.
As better shown in fig. 4, the hinging elements 43 are connected to the base portion 40 of the frame 4 by pins along pin shafts 45 parallel to the axis of rotation of the caster 50. The hinge element 43 comprises a shaped engagement seat 44 in which a correspondingly shaped end 60 can be positively engaged, this end being the end of a specific operating lever 6 of the outdoor furnishing element 100 (as shown in fig. 4 to 6), this operating lever 6 here also constituting a mechanical security key for controlling the locking device of the handling system 5. The engagement seat 44 is preferably configured to define a positively inclined coupling direction with respect to a horizontal plane containing the rotation axis of the caster 50 associated with the articulation element 43, for example an engagement direction forming an angle α comprised between about 30 ° and about 45 ° with respect to said horizontal plane (see fig. 5).
Fig. 5 and 6 show the handling system 5 in a locked operative configuration and a released operative configuration, respectively.
In fig. 5, the base portion 40 of the frame 4 is in contact with the resting surface on which the outdoor furnishing element 100 itself is placed, under the effect of the weight of the entire outdoor furnishing element 100. In this case, the caster 50, which does not protrude or is at most only flush with respect to the lower face of the base portion 40, is not held or insufficiently held on the resting surface. The handling system 5 is thus automatically in the locked operating configuration and the outdoor furnishing element 100 acts in all respects as a fixed outdoor furnishing element, in particular being able to effectively perform the function of a traffic deterrent element.
The handling system 5 is brought into the released operating configuration (shown in figure 6) by inserting the operating lever 6 and its shaped end 60 in a specific engagement seat 44 provided in the hinging element 43 and pushing the operating lever 6 itself downwards, as indicated by the arrow F. This action, thanks to the action of the lever and to the articulated connection between the articulated element 43 and the rest of the frame 4, simultaneously generates a downward thrust on the caster 50 associated with the articulated element 43 (acting as a fulcrum) and lifts the base portion 40 of the frame 4 at the articulation area of the articulated element 43. After lifting, the entire base portion 40 of the frame 4 is tilted towards the side opposite the hinging elements 43, where the second pair of casters 50 of the handling system 5 is housed, so that the second pair of casters 50 are also pushed into contact with the resting surface. In this case, all the casters 50 are held on the resting surface of the outdoor furnishing element 100, and also constitute the only contact points with the outdoor furnishing element 100. Therefore, the carrying system 5 is in the release operation state, and the outdoor furnishing element 100 can be manually moved by pulling or pushing of the operation lever 6.
The handling system 5 is kept in the release operating configuration as long as sufficient force is exerted on the operating lever 6 to keep the base portion 40 of the frame inclined and the caster 50 in contact with the resting surface. When the action of such force ceases, the handling system 5 automatically returns to the locking operating configuration, due to the effect of the weight of the entire outdoor furnishing element 100.
When the outdoor furnishing element 100 is used in a public environment, for example in a city environment, and in particular as a traffic deterrent element, the operating lever 6 required for releasing the above-mentioned handling system 5 is only available for a person authorized to carry the outdoor furnishing element 100 by himself. For this purpose, the outdoor furnishing element 100 may advantageously comprise a housing 7 for the operating lever 6, the operating lever 6 being removable from the housing 7 only by authorized personnel. In the embodiment of the outdoor furnishing element 100 shown in fig. 1 to 6, the cavity of the hollow profiled element of the frame 4 (see fig. 1 and 3) advantageously serves as a housing 7 for the operating lever 6, which cavity can be accessed in a controlled manner through a hatch (not shown) which can be opened with a specific mechanical, electronic or electromechanical security key.
According to one embodiment shown in fig. 9 to 14, the locking device comprises a first operating element 152 and a second operating element 153, the first operating element 152 rotating integrally with one or more of the castors 150, the configuration of the second operating element 153 being variable between a neutral configuration and an active configuration. In the neutral configuration, the second operating element 153 does not act on the first operating element 152, thus allowing the first operating element 152 to rotate with the wheel. Conversely, in the active configuration, the second operating member 153 acts on the first operating member 152, locking its rotation.
The locking device further comprises switching means configured to switch the configuration of the second operating element 152 between said neutral configuration and said active configuration.
An embodiment of a handling system, in particular an embodiment of a locking device, is described with reference to fig. 7 to 12. The parts functionally corresponding to the first and second operating elements are also indicated by the same numerals 152, 153 already used above.
Referring to fig. 7-10, the passive handling system 15 is mounted directly in the base plate 13 without interposing a removable frame, and the base plate 13 is configured to directly accommodate all the components of the handling system 15 itself.
As shown in fig. 7 and 8, the base plate 13 comprises a metal plate 130 (e.g. a steel plate), the metal plate 130 being provided with a cavity facing the outer face of the base plate 13 for accommodating components of the handling system 15. If a fixed outdoor furnishing element 100 is required, and therefore no handling system is required, a metal insert provided with a rubber bumper (not shown) may advantageously be applied in such a cavity, in order to improve the friction characteristics of the outdoor furnishing element 100 on the respective rest surface. In this case, a structure is also provided on the face opposite to the base plate 13, here made in particular as a metal mesh or cage 131, for incorporation into the solid core 2. The base plate preferably also comprises a hooking element 132 for hooking the external lifting device.
The handling system 15 comprises two pairs of castors 150 fitted on respective swivel pins 151, and a locking device by means of which, in this case, the rotation of the castors 150, and therefore the operation of the handling system 15, can be inhibited or allowed.
The caster 150 is housed in the base plate 13 so as to project with respect to a substantially flat outer face of the base plate 13 and is therefore always in contact with the resting surface on which the outdoor furnishing element 100 (see fig. 10) is placed.
As shown in particular in fig. 9 and 10, the locking device comprises one or more fins (as first operating elements 152) projecting radially from each of the two rotation pins 151 of the caster 150 and preferably extending longitudinally for a limited extension of the rotation pins 151 themselves. The locking device comprises a pair of electric pistons 153 (as second operating elements 153), each of which is housed in the base plate 13 so as to interact with a respective fin 152 of one of the rotation pins 151. The longitudinal development of the rotation pin 151 with fins 152 and of the electric piston 153 are preferably aligned with each other along a single direction. The motorised piston 153 assumes an active configuration in which the movable portion of the motorised piston 153 interacts with said fin 152, preventing rotation of the motorised piston and locking rotation of the pin 151. In this case, the handling system 15 is in the locked configuration (as shown in fig. 9 and 10). The electro-dynamic piston 153 may also assume a neutral configuration, after which the electro-dynamic piston 153 does not interact with the fins 152, thus allowing the wheel 150 to rotate. In contrast, in the retracted state, the piston rod of the electric piston 153 does not interfere with the fin 152 on the rotation pin 151, whereby the rotation pin 151 and the corresponding caster 150 can freely rotate. In this case, the handling system 15 is in a release configuration (not shown).
The electric piston 153 is controlled by a switching device 200, which switching device 200 changes its configuration between said neutral configuration and said active configuration. In this regard, the switching device preferably includes a wireless receiver 154, particularly
A receiver capable of receiving control signals from a suitable electronic user device (e.g., a smartphone or other dedicated device) and capable of sending a suitable release or lock signal to the motorized piston 153. The control signal is issued after the introduction of a control code into the electronic device, which code is known only to persons authorized to handle the outdoor furnishing element 100 and serves here as an electronic security key for the locking device of the handling system 15.
Fig. 11 and 12 relate to an alternative embodiment to that shown in fig. 9 and 10, in which a crown wheel or sector gear is provided on the rotation pin 151 as the first operating element 152 and in place of the fins, and in which a lever apt to assume an engagement configuration with the crown wheel is provided as the second operating element 152, following which the rotation of the crown wheel ring is blocked. This is shown in fig. 11 and 12. Of particular note is how the lever has an end 153A which, in the engaged configuration, is easily placed between the two teeth 152A of the crown wheel 152. The second operating element 152 in the shape of a lever can also assume a neutral (or non-coupled) configuration, after which the second operating element 152 is not engaged in a crown wheel which remains free to rotate integrally with said rotation pin 151 (this condition is not shown in the figures).
The switching means in this embodiment may comprise an electronic lock 162, the electronic lock 162 changing the operating configuration of the lever between the neutral configuration and the active configuration. In particular, such switching means cause the movement of the lever, whereby the end 153 of the lever 153 disengages from the teeth of the crown wheel 152. Such an electronic lock 162 may be connected to the wireless receiver 154 in a manner similar to that provided for the embodiment shown in fig. 9 and 10 described above.
Fig. 13 and 14 relate to another variant of the locking device according to the invention. In this embodiment, the first operating element 152 corresponds to the first operating element 152 provided for the solution in fig. 9 and 10 (i.e. it is in the shape of a fin 152 protruding from one of the rotation pins 151). The second operating element 153 acts as a switching device rather than adopting the configuration shown in fig. 11 and 12. That is, the second operating element 153 adopts a lever configuration, and the switching means includes an electronic lock. The operating principle of the first operating element 152, the second operating element 153 and the switching means is similar to that described above for the solution in fig. 9 to 12.
The electronic user device by means of which the control signal for locking/releasing the locking device of the handling system 15 is intended can also be advantageously configured to perform an additional monitoring function of the handling of furnishing elements 100 and/or a function of managing the authorization of the user to perform such an operation. These functions include: for example, data relating to the time at which the user sent the lock/release command is recorded; sending such data to a command center at preset time intervals or in real time; setting a duration of a released state of the locking device; enabling/disabling a user on the electronic user device. These functions may be implemented in the electronic user device by dedicated software.
The battery 155 is used to power the power piston 153 (or electronic lock) and the receiver 154. Additionally, conventional electrical connection means (not shown) may be provided for connection to an external power source, which is available if the battery 155 is dead.
The locking device of the handling system 15 preferably also comprises manual control means which are available, for example, in the event of non-operation of the receiver 154. As shown in particular in fig. 9, in the preferred embodiment shown herein, such manual control means is configured as a rack system (rack system) in which a pair of parallel toothed bars 156 are engaged with a common gear wheel 157, each toothed bar 156 being operatively connected to one of the electric pistons 153. Rotation of the gear 157 causes simultaneous translation of the toothed rod 155 in opposite directions and, therefore, retraction or extraction of the piston rod of the electric piston 153, depending on the direction of rotation of the gear 157. The gear 157 may be operated by a lever 158, which lever 158 may be accessed by a special socket wrench (socket wrench) 159.
The manual control means, in particular the lever 158, constitute a mechanical activation key which replaces the electronic or electric activation key provided by the receiver 154 or in any case allowed. In essence, the switching means can be activated by a key, which can thus be mechanical, electrical or electronic.
The special features of the handling system 15 described above, and in particular of its locking device, can also be implemented in an embodiment of the outdoor furnishing element 100 in which the handling system is mounted in a removable frame associated with the base plate of the outdoor furnishing element 100 itself, as is the case with the embodiment in fig. 1 to 6.
With particular reference to fig. 1, a preferred embodiment of a process for manufacturing an outdoor furnishing element 100 is now described.
The exterior case 1 of the outdoor furnishing element 100 is formed in a first step of the process.
In order to allow maximum configuration flexibility of the housing 1 within the scope of an industrial production process and at affordable costs, computer-aided design (CAD) methods, computer-aided manufacturing (CAM) methods and subsequent manufacturing by Computer Numerical Control (CNC) equipment are advantageously used in this step, preferably in an integrated manner therebetween.
In particular, a three-dimensional computer model of the housing 1 is first created or purchased, for example in the form of a CAD file. The three-dimensional computer model is then computationally converted, for example by CAM software, into a set of machining instructions for performing numerically controlled machining. The set of machining instructions thus obtained is then sent to a numerically controlled manufacturing machine.
The realistic manufacturing of the housing 1 provides the shaping of the weight material, in particular the polystyrene foam, in particular by subtractive machining processes, such as milling, turning and/or drilling or other suitable machining performed by one or more numerically controlled machine tools.
The shaped casing 1 thus obtained is associated in successive steps with the substrate 3 or 13 of the outdoor furnishing element 100 prepared beforehand. The base plate 3 or 13 is applied in particular in a recessed portion of the casing 1, dedicated to delimiting, together with the base plate 3 or 13 itself, a closed cavity 10, the closed cavity 10 being intended to house the solid core 2 of the outdoor furnishing element 100.
Then, at least one resin layer (in particular polyurethane resin) is applied externally on the casing 1 to reinforce and/or protect the casing. The application of the resin layer can also be conveniently carried out in an automated manner, for example by means of conventional robotic spraying equipment.
The resin layer is applied so that it preferably also extends over the substrate 3 or 13, or at least over a portion of the substrate 3 or 13, so as to also integrate the substrate 3 or 13 with the casing 1 when the solid core 2 is not yet present. Instead of or in addition to the resin layer extending to the substrate 3 or 13, the substrate 3 or 13 may be fastened to the housing 1 by glue or other suitable fastening means.
In a subsequent step, the solid core 2 is directly produced in the semi-finished product consisting of the housing 1 and the substrate 13 by filling the cavity 10 with a solid or settable material.
This step is carried out by pouring an at least temporarily pourable material, in particular aerated concrete or another cementitious material, into the cavity 10 through an opening 11 provided specifically during the processing of the casing 1. This material fills the cavity 10, simultaneously binding the anchoring structures of the substrate 3 (preferably the anchoring structures present on the internal face of the substrate 3) and, once cured, forming a weight having a shape corresponding to the shape of the cavity 10 itself, preferably adhering to the surfaces of the external casing 1 and the substrate 3 delimiting this cavity. The opening 11 is preferably also completely filled with at least temporarily pourable material until the level of the outer surface of the outer shell 1 is reached.
In a next step, a surface finishing treatment and/or various finishing layers (such as, for example, a gel layer, a particle layer or a paint and/or adhesive film layer) may be implemented/applied on the casing 1 (i.e. on the at least one resin layer previously applied thereon).
At the end of the above steps, a fixed finished outdoor furnishing element 100 having the desired external shape is obtained.
If a mobile solution is instead required, the outdoor furnishing element 100 is provided with a passive handling system, which may be mounted directly in the base plate 13 (as in the embodiments of fig. 7 to 10) or in a separate frame 4 associated with the base plate 3 (as in the embodiments of fig. 1 to 6).
