Abstract
A retractable cover for protecting designated area and spaces. A stationary rigid portion receives telescopically extending portions movable over guiding assemblies to house vehicles and other objects and protect them. When the telescopic rigid portions are fully extended, they engage and interlock with seals resulting in a water tight structure. Also, the engagement is used to move and/or stop contiguous portions through the use of outwardly extending tabs at the rear and front ends of the telescopic portions. The guiding assemblies include channels through which wheels that are rotatably mounted to the lowermost ends of the portions. The stationary portion can be mounted to a cover member that is hingedly mounted to the area adjacent to a cooperative hole for selectively housing the retractable cover.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention.




The present invention relates to collapsible housing, and more particularly, to a retractable cover with telescopically extending portions movable over rails or wheels to house predetermined areas and spaces to protect them.




2. Description of the Related Art.




Applicant believes that the closest reference corresponds to U.S. Pat. No. 3,415,260 issued to Hall in 1968 for an Extensible Canopy Structure. However, it differs from the present invention because the present invention has retractable portions with telescopically extending rigid portions. The canopy in the patented structure does not provide the same degree of protection as in the present invention. Furthermore, to implement Hall's patent, as shown in

FIG. 2

, the canopy has to be made out of a very thin material. Otherwise, a very bulky body would develop, or else, it would have to be removed. The present invention provides a volumetric solution.




Other patents describing the closest subject matter provide for a number of more or less complicated features that fail to solve the problem in an efficient and economical way. None of these patents suggest the novel features of the present invention.




SUMMARY OF THE INVENTION




It is one of the main objects of the present invention to provide a telescopically extending cover structure that is easily movable to house predetermined areas and spaces to protect them and the objects within them such as vehicles, pools, and other objects and structures.




It is another object of this invention to provide a telescopic system with portions that engage and interlock with cooperative seals resulting in a water tight structure.




It is yet another object of this invention to provide such a device that is inexpensive to manufacture and maintain while retaining its effectiveness.




Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.

36


;


36


′;


46


;


46


′;


56


;


56


′;


66


and


66


′ respectively, that are parallel and spaced apart relationship to each other. The side walls are perpendicularly mounted to top walls


36


″;


46


′″;


56


″ and


66


″.




As seen in

FIG. 1

, stationary portion


30


is anchored in place at a predetermined location. Portion


30


is shaped in such a way that it receives telescopic portions


40


;


50


and


60


in the retracted position. Portion


30


is slightly larger in size with just enough internal clearance to allow telescopic portion


40


to fit within the former, and telescopic portion


40


, similarly, is slightly larger in size than portion


50


and portion


50


is larger than portion


60


so that the former portions receive the latter portions when retracted. Portions


30


;


40


;


50


and


60


each include two spaced apart and parallel side walls


36


;


46


;


56


and


66


and top walls joining them. In the preferred embodiment, guiding assemblies


70


;


80


;


90


;


70


′;


80


′ and


90


′ can be implemented with channels on surface S. Guiding assemblies


70


;


80


;


90


;


70


′;


80


′ and


90


′ are of sufficient length to allow telescopic portions


40


;


50


and


60


to fully travel predetermined distances.




A seen in

FIG. 2

, telescopic portions


40


;


50


and


60


are fully extended. Telescopic portion


40


is movable over guiding assemblies


70


, and


70


′. Telescopic portion


50


is movable over guiding assemblies


80


and


80


′. Guiding assemblies


80


and


80


′ extend a distance equal to the length of assemblies


70


and


70


′ plus the length of portion


50


. In the same manner, guiding assemblies


90


and


90


′ extend a distance equal to the length of assemblies


80


and


80


′ plus the length of portion


60


. Guiding assemblies


70


;


80


and


90


(and


70


′;


80


′ and


90


′) are disposed in parallel and spaced apart relationship with respect to each other and extend a predetermined distance within portion


30


that is at least the length of portions


40


;


50


and


60


. In one of the applications, like the one shown in

FIGS. 1 and 2

, the present invention has cooperative dimensions to house a vehicle and protect it from the natural elements, such as sunlight, rain, wind, and hail.





FIG. 3

illustrates one of the preferred embodiments for guiding assemblies


90


and


90


′ (which can also be used for assemblies


80


and


80


′;


70


and


70


′). Channel


92


includes a substantially flat bottom surface


93


supporting longitudinally extending I-beam


94


with upper and lower flanges


94


′ and


94


″ at a spaced apart and parallel relationship with respect to each other. The lowermost end of portion


60


includes longitudinally extending cavity


62


with opposite surfaces kept at a spaced apart and parallel relationship with respect to each other. Wheels


86


and


86


′ are rotatably mounted to walls


65


and


65


′. Wheels


86


and


86


′ ride over flange


94


″ and their vertical movement is limited by upper flange


94


′. In this manner, telescopic portion


60


, for instance, can be readily moved along guiding assembly


90


.




As best seen in

FIG. 4

, a partial cross-section of retractable cover


10


is shown in the expanded or extended position. Stationary portion


30


is anchored to a fixed location, typically against a stationary wall W. Front end wall


32


, perpendicularly mounted to wall


36


, serves to stop telescopic portion


40


at a predetermined distance when the latter is expanding by making contact with rear end wall


44


, which is perpendicularly mounted to wall


46


. Also, perpendicularly mounted to wall


46


is front end wall


42


. Front end wall


42


extends outwardly defining tab


48


and inwardly with end wall section


49


. Tab


48


serves to stop telescopic portion


40


at a predetermined distance by making contact with front end wall


32


in the retracted position.




Similarly, wall section


49


engages with rear end wall


54


when the housing is being retracted. Rear end wall


54


is perpendicularly mounted to wall


56


of telescopic portion


50


. When retracting the present invention, stopper tab


48


makes contact with wall


32


(and being lodged within cavity


33


) to stop the retracting movement of telescopic portion


40


. Telescopic portion


50


, when retracted, fits within telescopic portion


40


. Similarly, front end wall


52


, perpendicularly mounted and slightly extending beyond wall


56


, includes outwardly extending tab


58


that makes contact with front end wall


42


. Wall section


59


engages with rear wall


64


when the housing is being retracted. In the preferred embodiment, tabs


48


,


58


and


68


are received within cavities


33


,


43


and


53


, respectively. In this manner, the front of portions


30


,


40


,


50


and


60


are flush when retracted, thereby retracting telescopic portion


40


. In the same manner, portion


60


fits within portion


50


and tab


68


makes contact with front end wall


52


when retracting. Additional telescopic portions may be added or deleted utilizing the system described above, depending on the requirements.




In

FIG. 5

a portion of the engagement between portions


50


and


60


is shown. The primed numbers are used since they correspond to the opposite side as those shown in FIG.


4


. Stopper tab


68


′ is received within cavity


53


′. The engagement of wall


66


′ with wall


56


′ is water tight, in the preferred embodiment, or at least substantially water tight. This can be accomplished with a sealing member that could be foam


61


mounted, or equivalent material, on rear wall


64


, as shown in FIG.


6


. This is similarly done in rear walls


44


and


54


to accomplish the sealing function.




In

FIG. 6

a detail of the engagement between telescopic portions


50


and


60


is shown in the expanded position. The relative dimensions of the different elements are represented a little exaggerated. Preferably tighter spacing and clearances provide a better and more volumetrically efficient structure.





FIGS. 7 and 8

represent another embodiment for the present invention, in expanded and retracted positions, respectively, where the portions have different dimensions to be used for another purposes, such as for protecting swimming pools P. This configuration may additionally include a hole


101


in surface S for storage purposes. Stationery portion


130


is rigidly mounted to wall


100


. Base member


102


is perpendicularly mounted to wall


100


and provided with hinge assembly


105


at one of its longitudinal vertex. In the retracted position, all the telescopic portions are housed within stationary portion


130


. Wall


100


can then be pivoted and brought to the same plane as surface S. The entire structure is hidden inside longitudinal cavity


101


returning usable area while providing storage convenience. Hole


101


is provided for convenient storage purposes.




Telescopic portions


40


;


50


and


60


, once retracted, interlock each other through tabs


48


;


58


and


68


and cavities


33


;


43


and


53


. Portion


40


engages stationary portion


30


through tab


48


and cavity


33


. The group of these portions, being interlocked to each other, are then rotated inside base member


101


after removing pins


20


. Pins


20


have cooperative dimensions and strength characteristics to be inserted through loops


21


to withstand a predetermined weight of the entire assembly. To keep the different portions interlocked, pin member


25


is inserted through holes


24


in each one of portions


140


;


150


;


160


;


170


;


180


;


190


;


200


;


210


and


220


, as seen in FIG.


7


.




Present invention


10


is made of a durable material such as fiberglass, aluminum or the like, and made to withstand natural weather elements, and intrusions such as flying objects (balls, etc.), trespassers or accidents that could damage the protected property.




The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
