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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings, where the present invention is generally referred to with numeral
10
, it can be observed that it basically includes stationary portion
30
, telescopic portions
40
;
50
and
60
, and guiding assemblies
70
;
80
;
90
;
70
′;
80
′ and
90
′. Portions
30
;
40
;
50
and
60
include, side walls
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.
