Definitions
- the present invention relates to a multi-service pedestal, in particular for ports and marinas, that is able to provide a variety of utilities such as electricity, tap water, television and telephone services to moored vessels, cabin cruisers and ships, generally called cruisers in the following.
- the pedestal according to the invention can be used also in camping areas for recreational vehicles and temporary shelters.
- Stoves and portable air conditioners are often used for the air conditioning within small cruisers. However, they consume a lot of electrical power and, furthermore, can cause fire as a result of their possible overheating.
- U.S. Pat. No. 5,848,536 discloses a marine air conditioner, which could also be used as a heat pump.
- the basic design according to the invention is highly advantageous for almost any size boat . . . the air conditioner according to the invention has a very low volume to cooling capacity ratio, and high efficiency”.
- the conditioner is associated with a cooling water pump whose inlet conduit passes through the hull of the boat for sucking the cooling water for the heat exchange with the condenser of the air conditioner.
- a marine system of this kind which is called hydronic as it uses the circulation of water for the transfer of thermal power, is produced by Thermowell, Lecce, Italy.
- a central conditioning apparatus such as a heat pump or a refrigerator, is placed in a room of a vessel, and its heat exchanger is cooled with sea water by a suction pump.
- the central conditioning apparatus is connected through a delivery pipe and a return pipe to a fan coil remotely situated on the same vessel for air conditioning.
- U.S. Pat. No. 4,967,569 discloses a portable air-conditioning unit to be placed on a boat deck.
- the portable air-conditioning unit is enclosed in a shell divided into two compartments internally.
- a first compartment containing a cooling coil and a fan, communicates only with a boat cabin to be conditioned through a hatch; the first compartment sucks internal air by a suction duct, cools said air and feeds back it into the boat cabin by a delivery duct.
- the second compartment is in contact with external air that cools a condenser of the air-conditioning unit.
- this air-conditioning unit needs to be transported onto the deck of the boat to be refrigerated and positioned so as to be adapted to its hatch. Besides the drawback arising from the transport of the air-conditioning unit and the adjustment of its position in situations that are different from boat to boat, there is the problem of a poor performance due to the fact that the heat exchange takes place in the air conditioner only with the air.
- the present invention aims to overcome the above mentioned drawbacks associated with the installation of a fixed air-conditioning system on board of a vessel, but also with the transport of an air conditioner and the adjustment thereof to the hatch or other opening of a cabin to be conditioned.
- a main purpose of the present invention is to provide an air conditioning within a moored cruiser without the need to install a central conditioning apparatus on board, i.e. the main part of a conditioning system for heating and cooling the air.
- the present invention provides a multi-service pedestal, in particular for a quay of a port or marina, pedestal that has a support structure and is adapted to provide various utilities, such as electricity, tap water, telephone and television connections, to a cruiser moored at the quay, further comprising a central conditioning apparatus which is situated in the multi-service pedestal and is able to be connected to a terminal unit located on board the moored cruiser for conditioning indoor air.
- the invention provides users with a simple, safe and cheap air conditioning and heating system.
- a user shall only have to accommodate on board a small fan powered terminal unit connected to the central conditioning apparatus for cooling or heating that is on a quay or pier, through a hose that functions as a sheath containing two pipes, namely a delivery pipe and a return pipe, which connect the central conditioning apparatus to the terminal unit; the pipes allow the circulation of chilled or heated liquid.
- An electric cable for the thermostatic control of the system is also contained in the aforesaid hose.
- the pedestal has a hollow load bearing structure that is mounted on the quay or pier and is electrically powered with a cable that enters the support structure and is connected to industrial sockets with interlock, in addition to an electrical socket for supplying the central conditioning apparatus.
- Passing through the hollow structure is a tube from the water mains for water outlets controlled by taps.
- the central conditioning apparatus is connected by hoses and quick couplings to two tubes that run within the load bearing structure, exit the base thereof and continue through the quay or pier or along them until they reach the water surface.
- One of the two tubes is a suction tube, which, suitably protected by a filter, sucks water.
- the other one after having served a heat exchanger, discharges the water.
- a pump located in the pedestal is provided in the suction tube.
- a LCD or LED screen Housed in the upper part of the pedestal, is a LCD or LED screen, duly inclined to allow a best vision.
- the LCD or LED screen via a cable connection or wi-fi, allows the user to take advantage of interactive promotions for dedicated user services that a manager decides to offer, as well as an advertising schedule.
- the support structure of the pedestal has profile, preferably of stainless steel, in a form of an omega rotated upwards, having a lower part connected by a support plate to the ground, an upper part in which a computer screen is placed frontally, and a central recess intended to removably receive said central conditioning apparatus.
- the omega-shaped profile of the support structure according to the second embodiment of the invention is somewhat narrow and is coated with slats protruding from both sides of the support structure.
- the slats are made of wood or composite material similar to those of the decking of the pier or quay to which it is attached.
- the central conditioning apparatus is encased in a housing made of material resistant to corrosion and is coated with the same slats of composite material or wood that cover the support structure that hosts it. So doing, an aesthetic continuity is obtained when both the central conditioning apparatus is inserted in the central recess of the support structure, and it is not.
- the central conditioning apparatus is connected to the fan powered terminal unit, which is enclosed in a durable, small, possibly isolated acoustically container. It includes a finned heat exchanger, a centrifugal fan and inlet grille.
- the support structure has a squared S-shaped profile, extending upward in a rearward inclined portion to receive a computer screen, the squared S-shaped profile comprising a C-shaped recess intended to removably receive said central conditioning apparatus and a lower part in the form of an inverted L that is adapted to receive a permanent housing for utilities.
- the support structure has a squared S-shaped profile, extending upward in a rearward inclined portion to receive the screen of a computer, the squared S-shaped profile comprising a C-shaped recess intended to removably receive said central conditioning apparatus and a lower part in the form of an inverted L.
- the C-shaped recess is pivoted by means of cylindrical hinges on the lower part in the form of an inverted L that is intended to removably receive a housing for utilities.
- Such housing is likely to be removed from the multi-service pedestal by turning upwards the C-shaped recess, after said central conditioning apparatus has been removed from it.
- a main advantage lies in its function of offering a comfortable temperature within a cruiser; other advantages include reduced size of the fan powered terminal unit, low noise due to the only presence of a fan in the room to be conditioned, easy maintenance, prevention of vandalism, theft or tampering, especially in the embodiments in which the housing of both the central conditioning apparatus and the utilities is removable from the support structure of the pedestal.
- Other advantages derive from the modularity of the multi-service pedestal according to the invention, which allows the manager to purchase the pedestal from the manufacturer thereof as desired, and to maintain it easily thanks to the removable housing of central conditioning apparatus and utilities.
- a decisive factor is the reliability in use: there is no need of heaters, portable air conditioners, or stationary air conditioning systems on board, with a result of greatly reducing the risk of fire due to overheating of electrical equipment, and of cruiser sinking due to a malfunction of the sea cocks.
- the advantage of the pedestal according to the invention is to provide a service to those who can not or do not want to bear the cost of purchasing a stationary air conditioning system on board or just do not have the sufficient space on their cruiser.
- the pedestal allows a reduced power consume with respect to heaters and portable air conditioners.

Abstract
A multi-service pedestal (1) in particular for ports and marinas, being provided with a support structure (10) and adapted to provide a variety of utilities, such as electricity, tap water, telephone and television connections, to a cruiser moored at a pier or quay, further has a central conditioning apparatus (6) which is located in the multi-service pedestal (1) and is adapted to be connected to a terminal unit (18) onboard the moored cruiser for conditioning the air within it through the heat exchange with a conditioning liquid. The support structure (10) has a front side (11) on which a computer screen (5) is installed.
Description
- The present invention relates to a multi-service pedestal, in particular for ports and marinas, that is able to provide a variety of utilities such as electricity, tap water, television and telephone services to moored vessels, cabin cruisers and ships, generally called cruisers in the following. However, the pedestal according to the invention can be used also in camping areas for recreational vehicles and temporary shelters.
- Small cruisers have commonly no air conditioning system within their cabin because of encumbrance and cost of maintenance thereof. The problem of air conditioning is particularly serious when the cruiser is in an area sheltered from the wind, e.g. a port or marina, especially when the weather is hot. Sometimes, as in lake areas, it is not possible to keep open portholes, hatches and windows during summer for ventilation, which allows mosquitoes and other annoying insects to come in.
- Stoves and portable air conditioners are often used for the air conditioning within small cruisers. However, they consume a lot of electrical power and, furthermore, can cause fire as a result of their possible overheating.
- U.S. Pat. No. 5,848,536 discloses a marine air conditioner, which could also be used as a heat pump. There is stated that “while the marine air conditioner according to the invention is particularly effective for boats in the twenty five foot range, the basic design according to the invention is highly advantageous for almost any size boat . . . the air conditioner according to the invention has a very low volume to cooling capacity ratio, and high efficiency”. The conditioner is associated with a cooling water pump whose inlet conduit passes through the hull of the boat for sucking the cooling water for the heat exchange with the condenser of the air conditioner.
- Even if the air conditioner described in U.S. Pat. No. 5,848,536 is particularly developed for the purpose, however, the encumbrance and maintenance drawbacks above mentioned as well as cost and noise of the cooling water suction pump remain the same. Furthermore, the installation of the air conditioner involves, as mentioned above, the drilling of the hull below the waterline that cause various problems, including psychological ones, related to this need.
- A marine system of this kind, which is called hydronic as it uses the circulation of water for the transfer of thermal power, is produced by Thermowell, Lecce, Italy. A central conditioning apparatus, such as a heat pump or a refrigerator, is placed in a room of a vessel, and its heat exchanger is cooled with sea water by a suction pump. The central conditioning apparatus is connected through a delivery pipe and a return pipe to a fan coil remotely situated on the same vessel for air conditioning.
- U.S. Pat. No. 4,967,569 discloses a portable air-conditioning unit to be placed on a boat deck. The portable air-conditioning unit is enclosed in a shell divided into two compartments internally. A first compartment, containing a cooling coil and a fan, communicates only with a boat cabin to be conditioned through a hatch; the first compartment sucks internal air by a suction duct, cools said air and feeds back it into the boat cabin by a delivery duct. The second compartment is in contact with external air that cools a condenser of the air-conditioning unit.
- It is understood that this air-conditioning unit needs to be transported onto the deck of the boat to be refrigerated and positioned so as to be adapted to its hatch. Besides the drawback arising from the transport of the air-conditioning unit and the adjustment of its position in situations that are different from boat to boat, there is the problem of a poor performance due to the fact that the heat exchange takes place in the air conditioner only with the air.
- The present invention aims to overcome the above mentioned drawbacks associated with the installation of a fixed air-conditioning system on board of a vessel, but also with the transport of an air conditioner and the adjustment thereof to the hatch or other opening of a cabin to be conditioned.
- A main purpose of the present invention is to provide an air conditioning within a moored cruiser without the need to install a central conditioning apparatus on board, i.e. the main part of a conditioning system for heating and cooling the air.
- To achieve the above mentioned purpose, the present invention, as defined in
claim 1 attached to this description, provides a multi-service pedestal, in particular for a quay of a port or marina, pedestal that has a support structure and is adapted to provide various utilities, such as electricity, tap water, telephone and television connections, to a cruiser moored at the quay, further comprising a central conditioning apparatus which is situated in the multi-service pedestal and is able to be connected to a terminal unit located on board the moored cruiser for conditioning indoor air. - Advantageously, the invention provides users with a simple, safe and cheap air conditioning and heating system. A user shall only have to accommodate on board a small fan powered terminal unit connected to the central conditioning apparatus for cooling or heating that is on a quay or pier, through a hose that functions as a sheath containing two pipes, namely a delivery pipe and a return pipe, which connect the central conditioning apparatus to the terminal unit; the pipes allow the circulation of chilled or heated liquid. An electric cable for the thermostatic control of the system is also contained in the aforesaid hose.
- Various embodiments of the multi-service pedestal according to the present invention are defined in the claims dependent on
claim 1. - According to a first embodiment of the invention, the pedestal has a hollow load bearing structure that is mounted on the quay or pier and is electrically powered with a cable that enters the support structure and is connected to industrial sockets with interlock, in addition to an electrical socket for supplying the central conditioning apparatus.
- Passing through the hollow structure, which can be made of steel, is a tube from the water mains for water outlets controlled by taps.
- The central conditioning apparatus is connected by hoses and quick couplings to two tubes that run within the load bearing structure, exit the base thereof and continue through the quay or pier or along them until they reach the water surface. One of the two tubes is a suction tube, which, suitably protected by a filter, sucks water. The other one, after having served a heat exchanger, discharges the water. A pump located in the pedestal is provided in the suction tube.
- Housed in the upper part of the pedestal, is a LCD or LED screen, duly inclined to allow a best vision. The LCD or LED screen, via a cable connection or wi-fi, allows the user to take advantage of interactive promotions for dedicated user services that a manager decides to offer, as well as an advertising schedule.
- In a second embodiment of the invention, the support structure of the pedestal has profile, preferably of stainless steel, in a form of an omega rotated upwards, having a lower part connected by a support plate to the ground, an upper part in which a computer screen is placed frontally, and a central recess intended to removably receive said central conditioning apparatus.
- The omega-shaped profile of the support structure according to the second embodiment of the invention is somewhat narrow and is coated with slats protruding from both sides of the support structure. The slats are made of wood or composite material similar to those of the decking of the pier or quay to which it is attached.
- The central conditioning apparatus is encased in a housing made of material resistant to corrosion and is coated with the same slats of composite material or wood that cover the support structure that hosts it. So doing, an aesthetic continuity is obtained when both the central conditioning apparatus is inserted in the central recess of the support structure, and it is not.
- Even in the second embodiment the central conditioning apparatus is connected to the fan powered terminal unit, which is enclosed in a durable, small, possibly isolated acoustically container. It includes a finned heat exchanger, a centrifugal fan and inlet grille.
- In a third embodiment of the invention, the support structure has a squared S-shaped profile, extending upward in a rearward inclined portion to receive a computer screen, the squared S-shaped profile comprising a C-shaped recess intended to removably receive said central conditioning apparatus and a lower part in the form of an inverted L that is adapted to receive a permanent housing for utilities.
- In a fourth embodiment of the invention, the support structure has a squared S-shaped profile, extending upward in a rearward inclined portion to receive the screen of a computer, the squared S-shaped profile comprising a C-shaped recess intended to removably receive said central conditioning apparatus and a lower part in the form of an inverted L. The C-shaped recess is pivoted by means of cylindrical hinges on the lower part in the form of an inverted L that is intended to removably receive a housing for utilities. Such housing is likely to be removed from the multi-service pedestal by turning upwards the C-shaped recess, after said central conditioning apparatus has been removed from it.
- Advantages of the invention are evident for both the manager of the pedestals on the quay and the users. A main advantage lies in its function of offering a comfortable temperature within a cruiser; other advantages include reduced size of the fan powered terminal unit, low noise due to the only presence of a fan in the room to be conditioned, easy maintenance, prevention of vandalism, theft or tampering, especially in the embodiments in which the housing of both the central conditioning apparatus and the utilities is removable from the support structure of the pedestal. Other advantages derive from the modularity of the multi-service pedestal according to the invention, which allows the manager to purchase the pedestal from the manufacturer thereof as desired, and to maintain it easily thanks to the removable housing of central conditioning apparatus and utilities. A decisive factor is the reliability in use: there is no need of heaters, portable air conditioners, or stationary air conditioning systems on board, with a result of greatly reducing the risk of fire due to overheating of electrical equipment, and of cruiser sinking due to a malfunction of the sea cocks. In general the advantage of the pedestal according to the invention is to provide a service to those who can not or do not want to bear the cost of purchasing a stationary air conditioning system on board or just do not have the sufficient space on their cruiser. Finally, the pedestal allows a reduced power consume with respect to heaters and portable air conditioners.

- Evident are the advantages of the present invention that consists of a combination of a multi-service pedestal for ports and marinas and an air conditioning system. The invention allows to offer fresh and warm air inside cruisers that have no stationary air conditioning system on board due to the encumbrance or cost thereof.
- The multi-service pedestal uses an air conditioning system comprising a central conditioning apparatus removably inserted in the multi-service pedestal, and a small, silent fan coil terminal unit onboard the cruiser when it is moored. The central apparatus and the terminal unit are connected through hoses that carry and circulate heated or chilled liquid. The temperature in the room to be conditioned is controlled by a thermostat inserted into the terminal unit, which also adjusts the speed of the air flow.
- The multi-service pedestal with air conditioning system takes advantage of its natural place near seas, lakes and rivers in order to use the water in the conditioning process as in most air conditioners installed on board vessels.
- The advantage lies in the fact that the water cooling pump and central conditioning apparatus remain on the quay or pier and only the small terminal unit is placed on board. Small boats can thus benefit from an air conditioning system that replaces dangerous heaters and bulk portable air conditioners.
- The multi-service pedestal with air conditioning system allows marinas and ports to offer a rental service of air conditioning system, with the result of increasing the safety of people and cruisers, the usability of the cruiser throughout the year and, consequently economic benefits for operators of marinas and ports that would increase their volume of business.
- The multi-service pedestal according to the present invention may be marketed with or without the air conditioning system, the central conditioning apparatus being a removable element and the pedestal being ready to host it via easy connection with pipes and cables.
- As an alternative to cooling with water taken from the surrounding environment, the central conditioning apparatus located on the multi-service pedestal can be fitted with an air cooling, possibly with forced ventilation.
- In its various embodiments, the multi-service pedestal has a simple design that allows rapid and economical maintenance of the various components that constitute it. The use of fully recyclable coating materials such as extruded wpc (wood plastic composite) made of wood dust and polyethylene, and the main steel structure, make the multi-service pedestal an environmental friendly product.
- Without departing from the invention, the multi-service pedestal can still be made with any design and material. Electrical and electronic components for controlling utilities and for metering energy and water, and further motion detectors, cameras, webcams, phone service or internet can be added.
- The central conditioning apparatus is enclosed in a housing made of a corrosion-resistant material that is coated with the same slats of composite material or wood covering the support structure that houses it. By doing so, an aesthetic continuity is obtained when the central conditioning apparatus is inserted into the pedestal.
- It should be appreciated that the multi-service pedestal according to the present invention may be placed, besides in ports and marinas, even on campsites or other picnic areas, where so-called recreational vehicles such as caravans, campers, motor homes park, or temporary and permanent shelters such as tents and bungalows for the outdoors are planned. Without making substantial changes, except that providing the open loop heat exchanger more convenient for the surrounding environment, the central conditioning apparatus can be removably placed in a support structure of a multi-service pedestal according to the invention and be connected to a terminal unit placed on the recreational vehicle or in the temporary or permanent shelter for conditioning the air within them by heat exchange with a conditioning liquid.
