## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application is a non-provisional of U.S. Provisional Patent Application Ser. No. 61/773,544, titled HELIPORT, filed Mar. 6, 2013, which is incorporated herein as if set out in full.
BACKGROUND
Helipads are areas or platforms designed for take-off and landing of helicopters and other vertical take-off and landing aircraft (collectively, “helicopters”). While such aircraft are able to operate on a variety of relatively flat surfaces, fabricated helipads and designated take-off and landing areas provide clearly marked hard surfaces away from obstacles where helicopters and other such aircraft can operate safely. Helipads have become common place in many commercial industries, including offshore oil platforms, news agencies, hospitals, large corporations, and municipalities, all of which frequently associate helipads with their main operating structures. For example, helipads are frequently located on large open areas of the surrounding grounds or rooftops of hospitals, fire stations, high rise commercial buildings, and the like. While far less common, helipads can also be located on rooftops of multi-story residential structures, such as condominiums.
Heliports are small facilities suitable for use only by helicopters and other vertical and take-off landing aircraft. Heliports typically contain one or more ground-level helipads and may have limited facilities such as fuel, lighting, wind direction indicators, and hangars. There are no heliports or other multi-level structures or buildings with helipads which are cantilevered outward from mid-level floors of the building. In many large cities around the world, heliports serve passengers that need to quickly move within the city or to outlying regions. Heliports have advantages over airports in that they can be situated closer to a town or the city center than an airport can be situated. To be sure, heliports require smaller operating areas due to the absence of runways needed for fixed-wing aircraft. The number of operating heliports and individual helipads, varies from city to city. People who use the heliports must usually shuttle to and from the heliport via car service or privately owned automobiles in order to reach interim or final destinations, such as businesses or homes. This can result in a significant delay in an individual's time, especially when the individual needs to make several trips each week by helicopter. Frequently, the limited number of heliports, individual helipads, and surrounding city congestion and traffic, limit the use and potential effectiveness of heliports for frequent users.
What is needed is a way to combine multi-story commercial and residential urban spaces with helipads and the full services of a major heliport which would otherwise be located solely at ground level, distant and unrelated to customers in such commercial and residential spaces.

DETAILED DESCRIPTION
Embodiments are described more fully below with reference to the accompanying figures, which form a part hereof and show, by way of illustration, specific exemplary embodiments. These embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the invention. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. Therefore, the following detailed description is not to be taken in a limiting sense.
According to the present technology, heliports may be provided in a number of different embodiments and configurations. Various embodiments of the heliport incorporate commercial and residential spaces with a plurality of helipads, all within one or more multi-story buildings. Helipads, associated with such buildings, may be placed on conventional rooftop structures, adjacent ground areas or extend outwardly from the sides of the building, between the ground level and roof level portions. In different embodiments, the helipads may cantilever out from the sides of the building or may be positioned on platforms that extend between oppositely faced sides of adjacent building structures.
With reference to FIGS. 1-4, a heliport 100 is configured from a multi-story building that is portioned into segments. A ground level portion 102 is depicted as occupying the full footprint of the heliport 100. While the ground level portion 102 is depicted as including only a single story, it is contemplated that the ground level portion 102 could occupy a plurality of stories and the configurations for the ground level portion 102 are endless. It is also contemplated that the ground level portion 102 may not terminate at actual ground level. In some embodiments, the ground level portion 102 may extend well below the ground surface and provide various subterranean levels that may be occupied by commercial, residential or utility spaces (such as parking garages), and the like. The ground level portion 102 may otherwise provide common services found within a ground level of a structure including commercial spaces for food, retail stores, reception, building security and recreational areas.
The heliport 100 continues to rise above the ground level portion 102. In the depicted embodiment, the heliport 100 includes a multi-segmented, or tiered, building structure that extends upwardly from the ground level portion 102. A first tiered segment 104 extends upwardly from the ground level portion 102 and terminates at a first tier rooftop portion 106. As with the aforedescribed ground level portion, any “rooftop level portion” herein may include one or more of the top stories of any building or tower, depending on its configuration. It will not, generally speaking, include only the upper roof surface of the buildings or towers. The first tier rooftop portion 106 may include a large, open area that may include one or more helipads 108, having one or more various helipad markings that aid in the landing and take-off of aircraft. In some embodiments, the helipads 108 are marked to include two or more concentric circles to designate the area occupied by each helipad 108. The innermost circle within each helipad 108 may be formed or otherwise designated using lights or other luminescent and non-luminescent markings, which may include paint and the like. This inner circle designates the touchdown and lift-off area (TLOF) 110. At least one additional circle may extend around the TLOF 110 and be marked with similar lights or other visual indicators. This second, exterior circle is known as the final approach and take-off area (FATO) 112. Lights used to indicate the TLOF 110 and FATO 112 may be elevated or inset. It is contemplated that the lights may be white, as recommended by the International Civil Aviation Organization and Federal Aviation Administration. It is also contemplated that yellow or amber, which was the former standard and is still preferred in many locations, may be used in place of or in conjunction with white lights. However, it is understood that there is a great deal of variance in color depending on the owner, jurisdiction and geographic location of the heliport. All the lights may be the traditional incandescent variety; use of light-emitting diodes with brightness control is preferred. The TLOF and FATO lights may also be marked by surface floodlights (not depicted). Lighted wind cones (not depicted) may also be located proximal the helipads 108, as such devices are required in most jurisdictions. Rows of lead-in lights (not depicted) may also mark helipads 108 to indicate a preferred direction of approach, depending on the orientation of the heliport 100 and adjacent structures. Visual slope guidance systems (such as HAPI, PAPI, etc.) may also be associated with the helipads 108 as deemed desirable or necessary according to the use of the helipads 108 and mark their location. Radio control of all helipad lighting by the pilot via an automated ground-based controller may also be associated with the helipads 108.
At a top rearward portion of the first tier rooftop portion 106, a hangar 114 may extend rearwardly from the first tiered segment 104 into adjacent portions of the building structure. In some embodiments, it is contemplated that the hangar 114 will include an opening that is sufficiently sized to accommodate various types of helicopters. In particular, this opening may be at least two stories tall and may be left open or selectively closable using one of various retractable or otherwise closable bay doors. It is contemplated that the hangar 114 will include facilities for servicing, maintaining and storing aircraft. Such facilities may include refueling services, where the fuel is either stored locally to the hangar or delivered to the hangar by pipeline from a storage tank facility offsite. Basic and advanced aviation mechanics facilities are also contemplated for continued upkeep and service of aircraft within the hangar 114. Open storage areas within the hangar 114 may be provided for temporary or a long term storage of one or more aircraft that do not need to be on a “ready status” on the helipads 108. Other equipment, such as aircraft relocation systems, such as helicarriers, light tow carts, universal tow carts, and various sizes of aircraft tugs and tow tractors, may be stored within the hangar 114 for locating the aircraft to and from the helipads 108 and hangar 114. Owners, tenants and other individuals in the building may have access from each floor of the building to the hangars on the same or other floors, and may have access from each floor directly to the helipad. Each floor may be used for one purpose or multiple purposes, including residential, commercial, retail, helipad uses.
With continued reference to FIGS. 1-4, the heliport 100 may include a second tiered segment 116 that extends upwardly from the ground level portion 102 and terminates at a second tier rooftop portion 118. In some embodiments, such as depicted in FIGS. 1-4, the second tiered segment 116 may extend higher than the first tiered segment 104, such that the second tier rooftop portion 118 is disposed at a higher altitude than the first tier rooftop portion 106. The second tiered segment 116 may be disposed to extend transversely with respect to the first tiered segment 104, such that they extend outwardly at an angle from a common rearward portion. As with the first tiered segment 104, the second tiered segment 116 may include a large open area on its second tier rooftop portion 118 to accommodate one or more helipads 108. The helipads 108 may be configured and accessorized as described previously. Similarly, a hangar 120 may be associated with a rearward portion of the second tier rooftop portion 118. The hangar 120 may be structured and otherwise accessorized in a manner similar to that described with respect to hangar 114. It is contemplated that facing the first tiered segment 104 and second tiered segment 116 in different directions will dispose their respective helipads 108 in locations that are sufficiently remote from one another such that aircraft may simultaneously land and take off without significant interference. Moreover, the alternating altitudes for the first tier rooftop portion 106 and second tier rooftop portion 118, in different angular orientations with respect to one another, may also provide a benefit during alternating wind and weather conditions for the landing and takeoff of aircraft. A railing 122 may be associated with the perimeter either or both of the first tier rooftop portion 106 and second tier rooftop portion 118 to provide necessary safety for individuals and crew who are operating near the perimeter of either rooftop.
With continued reference to FIGS. 1-4, the heliport 100 may be provided with a third tiered segment 124 that extends upwardly from the ground level portion 102 and terminates at a third tiered rooftop portion 126. As can be seen from the figures, the third tiered segment 124 is taller than the first tiered segment 104 or the second tiered segment 116. Accordingly, the third tiered rooftop portion 126 is disposed at an altitude higher than those of the first tier rooftop portion 106 and second tier rooftop portion 118. The third tiered segment 124 extends upwardly from a central core that passes through each of the first tiered segment 104, second tiered segment 116 and a portion of the ground level portion 102. Due to the fact that the third tiered rooftop portion 126 is the highest platform of the heliport 100, a control tower 128 may be associated with the third tiered rooftop portion 126. In various embodiments, the control tower 128 may be provided in a plurality of different configurations that extend upwardly from the third tiered rooftop portion 126. In the depicted embodiments, the control tower 128 has a generally circular perimeter with windows that afford control tower personnel with a 360 degree view of the skyline surrounding the heliport 100. It is contemplated that the control tower 128 may be provided as a single story structure or may extend several stories above the surface of the third tiered rooftop portion 126, as the heliport 100 and its position with respect to adjacent manmade and natural structures dictates. It is contemplated that systems associated within the control tower 128 will include radar displays and live monitor displays of each helipad available for Local Control or Air Control, Ground Control, and Flight Data/Clearance Delivery. Regardless of particular configuration within the control tower 128, it is contemplated that sufficient facilities will be provided to coordinate with local and regional air control facilities and other airports, and heliports. The third tiered rooftop portion 126 may also include a helipad 108, as described previously. Similarly, a railing 122 may also be disposed at the perimeter of the third tier rooftop portion 126 for the safety of individuals operating on the third tier rooftop portion 126.
With further reference to FIGS. 1-4, the heliport 100 may be provided with one or more platforms 130 that cantilever outwardly from side portions of the heliport building. These side portions of the building may extend between the ground level portion 102 and the third tier rooftop portion 126. However, the side portions may also simply extend between either or both of the first tier rooftop portion 106 or second tier rooftop portion 118 and the third tier rooftop portion 126. Regardless of where the lower portion of such building side begins, the side portions will terminate at one of either the first tier rooftop portion 106, second tier rooftop portion 118, or third tier rooftop portion 126. In some embodiments, such as depicted in FIGS. 1-4, the platforms 130 cantilever outwardly from the side portions of the heliport 100. In particular embodiments, such as depicted, the platforms may cantilever outwardly from a pair of adjoining side portions. In this manner, the “side portion” may include a pair of side portions and/or a corner portion of the building. In this manner, the distal end portions of the platforms 130 extend away from the side surfaces of the heliport 100 at an angle. This limits direct visual or auditory engagement with activity on the platforms 130 with the sides of the heliport 100. It is contemplated that each platform 130 will include at least one helipad 108, as described previously herein. A walkway having a width of at least 20 feet may extend outwardly from the FATO 112 of each helipad 108 to allow individuals and equipment to move around the helipad 108. A railing 122 may extend upwardly from the edge portions of the platform 130 and extend around the entire peripheral edge of the platform 130. Hangars 132 and residential or commercial space or units 132 may be associated with each platform 130. The hangars 132 may be outfitted similar to hangars 114 and 120. In this manner, aircraft may be moved from the platform 130 into the hangar 132 and returned for takeoff. Within the hangars, service and maintenance of the aircraft may be performed and aircraft may be stored for any period of time. The hangars 132 may also be provided to have a ceiling height that is multiple stories high and may provide open sides that may be selectively closable with at least one retractable cover, such as retractable doors, windows, and the like. Portions of the same story or floor of the hangar, and/or floors above or below the hangar may be residential or commercial space or units, with direct access to the hangar.
With reference to FIGS. 5-8, another embodiment of the heliport of the present technology is depicted. Specifically, a heliport 200 is provided with a ground level portion 202 that may be provided in a manner similar to that described with respect to ground level portion 102. Accordingly, the ground level portion 202 may extend above or below the ground surface, nearly any number of desired stories according to the desired usage. It is contemplated that the ground level portion 202 may be used for commercial or residential operations. Other uses may include security, underground parking, and general reception areas.
The heliport 200 may be formed from at least two separate towers that extend upwardly from the ground level portion 202. In the depicted embodiment, a first tower 204 extends approximately 70 stories above the ground level portion 202. It is contemplated that the first tower 204 may be provided to have any number of stories according to the desired scope and usage of the heliport 200. A second tower 206 is positioned on an opposite end portion of the ground level portion 202 and extends upwardly therefrom. In the depicted embodiments, the second tower extends approximately 65 stories above the ground level portion 202. Accordingly, the first tower 204 extends approximately five stories above the upper most level of the second tower 206. The first tower 204 and second tower 206 are positioned to be spaced apart from one another. The open space between the two towers may be provided according to the desired needs of the heliport 200. However, in the depicted example, the space between the towers is provided to be approximately 120 to 150 feet.
The first tower 204 is provided with a first tower rooftop portion 208. Similarly, the second tower 202 is provided with a second tower rooftop portion 210. It is contemplated that the first tower rooftop portion 208 and second tower rooftop portion 210 will include sufficient open space to include at least one or more helipads 108 thereon. The helipads 108 on either or both of the first tower rooftop portion 208 and second tower rooftop portion 210 may be provided in a manner similar to that described with respect to the helipads 108 in the heliport 100. Similarly, a railing 212 may extend around the perimeter of both the first tower rooftop portion 208 and second tower rooftop portion 210 to provide safety for personnel conducting operations thereon. In view of the height advantage of the first tower rooftop portion 208, a control tower 214 may be provided thereon. It is contemplated that the control tower 214 will perform similar functions as that described for the control tower 128. Accordingly, the control tower 214 will be provided with similar systems and equipment for monitoring heliport control, ground control and local control or air control. As described with respect to the control tower 128, the control tower 214 may be provided in many sizes and configurations. However, the circular configuration depicted provides 360 degree views and provides a sufficient height above the first tower rooftop portion 208 to provide the needed aircraft control services.
With further reference to FIGS. 5-8, the heliport 200 may be provided with a plurality of platforms 216 that span the open space between the first tower 204 and the second tower 206. Accordingly, each of the platforms 216 that extend between the first tower 204 and second tower 206 will have a length of approximately 120 to 150 feet. Each of the platforms 216 will have a width of approximately 60-70 feet, depending upon the intended use of the heliport 200. Each of the platforms 216 will include at least one helipad 208 that are structured and accessorized according to the helipads 108 described previously herein. A railing 218 may extend along the side edges of each of the platforms 216 to ensure safety for personnel operating thereon.
The end portions of each of the platforms 216 may extend outwardly from hangars 220, which may be disposed in either or both of the first tower 204 or second tower 206. As described with respect to the hangars associated with heliport 100, the hangars 220 associated with the heliport 200 may include any number of aircraft support, maintenance, servicing, or storing services. The hangars 220 may be used for storage for any period of time as well as maintenance and the like. The openings to the hangars 220 may be provided to be several stories in height and may be left open or selectively closable by retractable doors or other similar structures, and may be combined with residential or commercial occupied units which are adjacent to the hangars and to the helipads, or on floors above or below the hangars or helipads. A catwalk 222 may extend between the first tower 204 and second tower 206. In the embodiment depicted, the catwalk 222 extends from the first tower 204 to the second tower rooftop portion 210. In this manner, access is easily granted to the helipads 108 disposed atop the second tower rooftop portion 210.
With regard to FIGS. 9-12, a third embodiment of the present heliport technology is depicted. Specifically, a heliport 300 is depicted as extending upwardly from a ground level portion 302. The ground level portion 302 may be provided in the manner similar to that described with respect to ground level portions 102 and 202. Accordingly, the ground level portion 302 may extend several stories above or below a ground surface to provide the commercial, residential and utility spaces so desired. A main tower 304 extends upwardly from a central portion of the ground level portion 302. While the main tower 304 is depicted as having a circular peripheral edge, the main tower 304 may be provided to have nearly any shape desired, according to the intended use of the heliport 300. The main tower 304 extends between the ground level portion 302 and a main tower rooftop portion 306. The main tower rooftop portion 306 is positioned to be the highest portion of the heliport 300. Accordingly, the main tower rooftop portion 306 provides a desirable location for the control tower 308. The control tower 308 may be provided in a manner similar to that described previously for control tower 128 and 214. However, it is contemplated that sufficient systems and facilities will be associated with control tower 308 so that it may provide sufficient heliport control, ground control, and local control or air control. The control tower 308 will also be provided with sufficient systems to communicate effectively with regional and local air traffic control facilities. The peripheral edge of the main tower rooftop portion 306 may be provided with a railing 310 that extends upwardly from the surface thereof to protect personnel conducting operations about the rooftop.
A plurality of platforms 312 may extend outwardly from the sides of the main tower 304. Specifically, the platforms 312 cantilever outwardly from the sides of the main tower 304. As described previously with respect to the platforms 130, associated with the heliport 100, the platforms 312 may each be provided with one or more helipads 108. These helipads 108 will be configured and accessorized, as described previously, with respect to the heliport 100 and heliport 200. Rearward end portions of each platform 312 may be associated with hangars 314 that extend into the main tower 304. The hangars 314 may be provided to have openings of several stories in height that may be selectively closable by retractable doors or other similar structures, and may be combined with residential or commercial occupied units which are adjacent to the hangars and to the helipads, or on floors above or below the hangars or helipads. However, it is also contemplated that one or more of the hangars 314 may be left in an open environment condition. The hangars 314 will be provided with facilities as described with respect to the hangars associated with heliports 100 and 200. Specifically, the hangars 314 may provide service, maintenance and storage facilities needed for aircraft that may use the helipads 108. Railings may extend outwardly from the openings for the hangars 314 to extend around the peripheral edge portions of the platforms 312 to provide safety for personnel conducting operations adjacent to the helipads 108.
