Abstract
A storage structure or hangar designed primarily for housing a sailplane or other small aircraft has a substantially T-shaped pre-fabricated upper frame support anchored to the ground at several locations, a first set of frame members mounted immovably to the upper frame support in areas where the fuselage and tail and the two wings are located when the sailplane or small aircraft is in the storage structure, and a second set of frame members hingedly mounted in part to the upper frame support and partly to first set of frame members. The second set of frame members are located substantially where the front or cockpit of the plane is located and in front of the wings. Panels covering the first and second frame members and enclosing the structure are mounted to the first and second frame members. A cable, chain or like mechanism operated by a winch raises the second set of hinged frame members together with the cover panels mounted thereon to allow the sailplane to be placed into the storage structure. The winch also lowers the second set of frame members to close the structure and enclose the plane therein. The winch is powered by a battery that is charged by a solar panel associated with the structure.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention is in the field of structures designed to house sailplanes and small aircraft. More particularly, the present invention pertains to a structure which is specifically suited for protecting sailplanes and other small aircraft from exposure to the elements.




2. Brief Description of Background Art




It is well known that small aircraft is best stored in hangars or like buildings where the aircraft is protected from exposure to the elements. This is particularly true for sailplanes (also known as gliders) which in modern times are usually made from fiber glass, carbon fiber or like synthetic material. It is known that these synthetic materials are severely damaged by prolonged exposure to the sun. However, storage space in hangars or like structures is usually limited in the airports and airfields where sailplanes are normally operated, and when storage space is available it is usually expensive. Sailplanes are often moved from one airfield to another or are retrieved from off-airfield landings in covered trailers in which the sailplane can be stored and transported but only if the wings are first disassembled from the fuselage. For this reason many sailplane owners or operators have specifically dimensioned trailers for each sailplane.




In order to avoid exposing sailplanes, especially sailplanes made from fiberglass, carbon fiber or like synthetic material to the elements the owners or pilots usually remove the wings from the sailplane and store the sailplane in its covered trailer even when there is no intention or need to move the disassembled sailplane from one location to another. However, as it is known by those familiar with sailplane operations, sailplane wings are heavy, and removing them can be burdensome and time-consuming, especially when this operation is performed by one person. Reassembling the wings to the sailplane to make it airworthy again is equally burdensome and time consuming. Moreover, the reassembly of the wings and reconnection of the control surfaces must be performed with absolute precision with no room for error, since failure of properly attaching the wings to the fuselage, and/or failure of properly connecting the control surfaces is likely to cause serious and possibly fatal crashes.




The present invention provides a solution to the problem of disassembling sailplanes for storage just to protect them from the elements, and provides convenient and relatively inexpensive storage space for sailplanes and other small aircraft.




SUMMARY OF THE INVENTION




It is an object of the present invention to provide storage space for housing a sailplane or like small aircraft whereby the sailplane or aircraft is protected from the elements.




It is another object of the present invention to provide storage space for a sailplane or like small aircraft that is relatively inexpensive to manufacture.




It is still another object of the present invention to provide storage space for a sailplane or like small aircraft that can be assembled at the site of usage from pre-fabricated parts.




It is yet another object of the present invention to provide storage space for a sailplane or like small aircraft which is easy to operate.




It is a further object of the present invention to provide storage space for a sailplane or like small aircraft that is operated by electric power without being dependent on a power grid.




These and other advantages are attained by a storage structure or hangar which has a substantially T-shaped pre-fabricated truss or upper frame support anchored to the ground at a plurality of locations, first set of frame members mounted immovably to the truss or upper frame support in areas where the fuselage and tail and the two wings are located when the sailplane or small aircraft is in the storage structure, and a second set of frame members hingedly mounted in part to the truss or upper frame support and partly to first set of frame members. The second set of frame members are located substantially where the front or cockpit of the plane is located and in front of the wings. Panels covering the first and second frame members and enclosing the structure are mounted to the first and second frame members. A cable, chain or like mechanism operated by a winch raises the second set of hinged frame members together with the cover panels mounted thereon to allow the plane to be placed into the storage structure. The winch also lowers the second set of frame members to close the structure and enclose the plane therein.




The foregoing and other objects and advantages attained by the present invention will become readily apparent from the following description taken together with the appended drawings where like numerals indicate like parts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




The following specification taken in conjunction with the drawings sets forth the preferred embodiment of the present invention in such a manner that any person skilled in the art can use the invention. The embodiment of the invention disclosed herein is the best mode presently contemplated by the inventor, although it should be understood that various modifications can be accomplished within the parameters of the present invention.




Referring now to the appended drawing figures, a preferred embodiment of the storage structure, storage unit or hangar


50


of the present invention is disclosed. It should be noted at the outset that the storage structure or hangar


50


of the present invention is designed primarily for storage of sailplanes which are also known as gliders. Sailplanes or gliders typically have small cockpits for one or two persons and the cockpits tend to be relatively low to the ground. Sailplanes or gliders also typically have long wings and a relatively narrow fuselage. All of the foregoing is especially true for the sailplanes that are made from fiberglass, carbon fiber or like synthetic material. Thus, the storage structure or hangar


50


of the present invention is primarily dimensioned for the housing of sailplanes, and in this specification the preferred embodiment of the storage structure or hangar


50


is shown and described in connection with the housing of a single sailplane. However, the invention is not so limited and the storage structure


50


of the invention can also be readily adapted for the housing and storage of other small aircraft, for example a small power plane.




It is an important feature of the storage structure or hangar


50


of the present invention that it can be readily assembled from pre-fabricated parts at a desired site, such as an airfield, where sailplanes operate. Principal components or parts of the storage structure or hangar


50


include a substantially T-shaped truss or upper frame support


52


that is best shown by itself in FIG.


7


. Conceptually, the T-shaped truss or upper frame support


52


has a frontal part


54


to which structures housing the wings and cockpit of a sailplane are mounted, and a rear part


56


to which structures housing the fuselage are mounted. The T-shaped truss or upper frame support


52


is advantageously pre-fabricated from steel in several sections and is assembled at the desired site from the several pre-fabricated sections. In the presently preferred embodiment the frontal part


54


is assembled from five pre-fabricated sections


58


, and the rear part


56


is assembled from two pre-fabricated sections


58


. Preferably, as in the herein described preferred embodiment each pre-fabricated section


58


is made of steel bars of substantially rectangular cross-section which are welded together to form the respective pre-fabricated section


58


. As is shown in

FIGS. 9 and 14

, the pre-fabricated sections


58


are attached to one another by bolts


60


and nuts


62


. Moreover, adjoining linearly lined up bars of the sections


58


are linked with a reinforcing internal steel tube or bar


64


, shown in FIG.


10


.

FIGS. 7

,


9


,


17


and


18


illustrate that the T-shaped truss


52


is attached to and is supported in its elevated position by three vertical posts


66


which are embedded in the ground


68


, preferably in concrete


70


. The cross-sectional view of

FIG. 15

illustrates in detail the mounting of the T-shaped truss


52


into the vertical post


66


by bolt


72


and nut


74


.




The simplified diagrammatic view of

FIG. 7A

illustrates conceptually the mounting and location of first and second set of frame members to the substantially T-shaped truss


52


.

FIG. 7A

is simplified for illustration, because it does not show vertical and diagonal reinforcing bars that form part of these structures. However, the vertical and diagonal reinforcing bars are amply illustrated in other drawing figures. The first set of frame members


76


rests on the ground and is also attached to the truss


52


.

FIGS. 11 and 12

show that the truss


52


includes tabs


78


that are mounted with bolts


80


and nuts


82


to the first set of frame members


76


. The first set of frame members


76


is also preferably pre-fabricated in multiple sections


84


and in the preferred embodiment these sections are attached to one another by the hose clamps


85


, as shown in detail by FIG.


13


. The first set of frame members


76


has no moving parts in the assembled storage structure or hangar


50


of the invention, and serve to support cover members or panels


86


which actually enclose a sailplane


88


in the storage structure or hangar


50


of the invention and protect it from rain, solar rays and other exposure to the elements. The second set of frame members


90


, also shown conceptually in

FIG. 7A

, is attached in part to the truss


52


and in part to the first set of frame members


76


. More specifically, the second set of frame members


90


include parts


92


which are hingedly attached to a frontal horizontal member


94


of the truss


52


and parts


96


which are hingedly attached to frontal horizontal members


98


of the first set of frames


76


. This attachment is by hinges


100


and is perhaps best shown in

FIGS. 19 and 21

while

FIG. 20

shows the hinge


100


in detail. The second set of frame members


90


is also preferably pre-fabricated from several sections


102


, as shown in

FIG. 19

for the part that is included in the right side of the hangar


50


and which provides the front cover for one wing of the sailplane


88


to be stored in the hangar


50


. The sections


102


shown in

FIG. 19

are attached to one another by nuts


104


and bolts


106


, although other types of attachment may also be used.




Generally speaking, connections or mounting between mechanical parts such as welding, bolting, using hose clamps or other types of clamps, U-bolts or types of mechanical fasteners are well known in the art. In many instances, which will be readily apparent to those skilled in the art in light of the present disclosure, the herein described and other types of known mechanical fastening devices and means are interchangeable or equivalent. For this reason, a person of ordinary skill in the art may be able to build on the basis of the present disclosure the hangar or storage structure


50


of the present invention utilizing different types of mechanical fasteners than the ones specifically described in connection with the preferred embodiment. For example, hose clamps may be substituted with bolts and nuts or welding. Bolts, nuts and other type of mechanical fasteners can, in many instances, be replaced by welding the respective parts together and such apparent variations or modifications of attaching parts together are within the scope of the present invention.





FIG. 8

also shows the location of first and second sets of frame members


76


and


90


in the storage structure or hangar


50


of the present invention relative to the truss


52


and a sailplane


88


which may be stored in the structure


50


.

FIGS. 1 through 4

shows the structure or hangar


50


with the cover members or panels


86


mounted on the first and second sets of frame members


76


and


90


. A door


108


is located in one of the sections


84


of the first set of frame members


76


to allow access to the interior of the storage structure or hangar


50


.




The cross-sectional views of

FIGS. 33 and 34

show in detail the mounting of the cover member or panel


86


to the frame members


76


and


90


. The cover members or panels


86


of the presently preferred embodiment comprise corrugated metal plates


86


, which are attached to the frames


76


and


90


with self-tapping sheet metal screws


110


. Foam


112


is located between the corrugated metal panels


86


and the frame members


76


and/or


90


to provide insulation. Instead of corrugated metal plates


86


, wood or plastic panels could also be attached to the members


76


and/or


90


to enclose the sailplane


88


and protect it from the elements.




Referring now primarily to

FIGS. 3

,


4


and


21


through


28


, opening and closing the storage unit or hangar


50


of the present invention is disclosed. A winch


114


is mounted to a vertical member


116


of the second set of frame


90


that serves as cover for the cockpit of the sailplane


88


. A cable or wire


118


is attached to the winch


114


and is lead through pulleys


120


to a second winch


122


in the rear of the structure


50


. The second winch


122


is shown in FIG.


16


. In the preferred embodiment the winch


114


is powered by a 12 volt battery


124


. The battery


124


is charged by a solar panel


126


that is placed on one of the cover plates


86


. The battery


124


and solar panel


126


are shown in FIG.


36


. Rotation of the winch


114


, powered by the battery


124


winds-up or releases the cable


118


depending on the polarity of the current which is supplied to it through a switch


128


shown in FIG.


36


. The second winch


122


of the preferred embodiment is hand operated and is intended for use only when for some reason or another the first winch


114


is inoperative. In alternative embodiments both winches may be electrically powered and/or may be powered by 110 AC current rather than by a D.C. battery.




When the winch


114


is powered through the switch


128


to take up the cable


118


, the hinged second set of frame members


90


are lifted so as to allow the movement of a sailplane


88


into or out of the hangar


50


. More specifically, first that part of the frame members


90


is lifted together with the corresponding cover panels


86


which encloses the cockpit of the sailplane


88


. The winch


114


rides up on the cable


118


together with the frame member


116


to which it is mounted. Sides of the frame members


90


are connected with a link


130


to the respective the frame members


90


that are hingedly mounted to the frontal horizontal members


98


and enclose the wings of the sailplane


88


. Details of the operation of the link


130


that in essence links the cockpit cover door with the wing cover door, are shown in

FIGS. 22

,


23


,


27


, and


28


. As these figures disclose, the link


130


is mounted to the respective frames members


90


in such a manner that the frame members


90


can pivot relative to the link


130


. Thus, as the frame members


90


forming the cockpit cover are lifted, the link


130


also lifts the frame members


90


forming the front cover for the wings of the sailplane


88


. When the polarity of current is reversed by the switch


128


, the winch


114


unrolls cable


118


and the frame members


90


forming the cockpit and wing covers are lowered, thereby closing the structure


50


and enclosing the sailplane


88


that may be present in the storage structure or hangar


50


. Limit switches


132


shown in

FIG. 36

prevent lifting the hinged frame members


90


too high or lowering them too low and therefore prevent damage to the structure.





FIGS. 5

,


6


and


30


through


32


disclose other features of the storage unit or hangar


50


of the present invention which further facilitate the movement of a sailplane


88


into and out of the storage structure


50


. Specifically

FIGS. 5 and 6

disclose a substantially circular indentation


136


or shallow dent in concrete


70


embedded in the ground


68


at a distance from the front of the structure


50


which substantially corresponds to the length of the wing of the sailplane


88


that is to be stored in the structure


50


. This makes it easy for a person (not shown) to push a sailplane


88


with its fuselage parallel with the front of the storage structure or hangar


50


at the proper distance from the structure


50


until the front wheel


138


of the sailplane


88


rests in the indentation


136


. Then the sailplane


88


is pivoted 90 degrees on its front wheel


138


, as shown in

FIG. 5

, before its is pushed into the structure


50


for storage.





FIGS. 30 through 32

disclose a trough


140


formed inside the structure


50


and in alignment with the rear part


56


of the T shaped frame support


52


. In the presently preferred embodiment the trough


140


is comprised of a 4″ by 6″ wooden board


142


that is disposed flat on the ground


68


and of two 4″ by 4″ or 4″ by 6″ wooden boards


144


positioned on their respective edges and attached to the 4″ by 6″ board


142


by wood screws (not shown). In alternative embodiments the trough


140


may be made of metal or plastic or of any combination of wood, metal and plastic materials.




As is known by those who are familiar with sailplane operations, sailplanes are frequently moved around by attaching a tail dolly


146


to the rear part of the fuselage


147


, as is shown in

FIGS. 31 and 32

. The tail dolly


146


causes the tail wheel


148


of the sailplane


88


to be lifted off the ground


68


, however the tail dolly


146


must not be attached to the sailplane


88


during flight because it significantly changes the weight and balance and is likely to cause a serious accident. Nevertheless use of the tail dolly


146


greatly facilitates transportation of the sailplane


88


on the ground, as for example when the sailplane


88


is moved from the hangar


50


to a take-off line, or when it is returned to the hangar


50


after flight. It is also customary to remove the tail dolly


146


from the fuselage


147


when the sailplane


88


is stored or hangared, principally because during prolonged storage the pressure by the straps and buckles attaching the tail dolly


146


to the fuselage


147


may discolor or damage the delicate synthetic material of the sailplane


88


.




To facilitate the movement of a sailplane


88


with a tail dolly


146


into and out of the storage structure or hangar


50


of the present invention and to avoid the need for lifting the relatively heavy tail of the sailplane


88


when the tail dolly


146


is removed, a ramp


150


is placed at the end of the trough


140


in a location where the tail wheel


148


of the sailplane


88


is to be located. The sloping part


152


of the ramp


150


begins high enough so that the tail of the sailplane


88


clears it as the sailplane


88


is pushed into the hangar


50


with the wheel


154


of the tail dolly


146


and the sailplane's front wheel


138


rolling in the trough


140


. To store the sailplane


88


and to render it easy to remove the tail dolly


146


the sailplane


88


is moved until its rear wheel


148


rests in an oval depression


156


provided in the ramp


150


, as is shown in FIG.


32


. In this position the wheel


156


of the tail dolly


146


is lifted off the trough


140


and the tail dolly


146


can be readily removed, and also reassembled when it is desired to move the sailplane


88


out of the storage unit


50


.





FIG. 29

illustrates an optional lock


158


which may be attached to one of the 4″ by 4″ or 4″ by 6″ boards forming the trough


140


and to a panel


86


to prevent unauthorized opening of the structure or hangar


50


. Another lock (not shown) is usually provided in the door


108


.




As noted above the storage structure or hangar


50


is preferably made from pre-fabricated parts. Although the steps of building the structure


50


should be apparent to those skilled in the art from the foregoing description, the preferred method of construction is briefly described below.




First and preferably a location on the ground


68


is prepared by selecting a suitable flat area, the trough


140


is built from wooden boards and the ground


68


is preferably covered with light gravel (not shown) to cover the base of the structure


50


. The vertical posts


66


are embedded in concrete


70


in the ground


68


, and the substantially T-shaped truss


52


is mounted to the vertical posts


66


. Sections


84


of the first set of frame members


76


are then placed on the ground and mounted to the truss


52


, and to each other, as applicable, followed by sections


102


of the second set of frame members


90


mounted with hinges


100


to the truss


52


, to each other, and to the first set of frames


76


, as applicable. The truss


52


and the frame members


76


and


90


can then be painted if so desired, and if they have not been painted before. Subsequently, the battery


124


, the switches, the door


108


, winches


114


and


122


and the cover plates or panels
