Abstract
A retractable screen panel installation for a garage door in which the screen panel may be held latched in a position overlying a lowermost section of a garage door, and selectively released to slide down to cover an opening created when the door is partially raised. A one handed operation of two laterally spaced latching mechanisms releases the screen panel by squeezing together two angled end pivoted release levers each connected to a respective cable release element.
Description
BACKGROUND OF THE INVENTION
This invention concerns screens for garage doors of a type which are mounted to the bottom of the door and are able to be released to slide down and cover the opening formed beneath the bottom edge of the door when the door is partially opened. Such a screen installation is shown in U.S. Pat. Nos. 5,611,382; 5,860,465; and 4,653,566.
Garage door screens are advantageous as they allow ventilation while preventing the entrance of animals, insects, wind blown debris, etc.
These screens are intended to be installed on standard 8 or 16 foot garage doors, with the screen being of equal length. This relatively long length makes it desirable for two are more latches to be used to hold the screen in an elevated position so that the screen panel does not tilt to become angled with respect to the garage door. These latches of necessity are widely spaced such that it is inconvenient and relatively slow to release the screen panels by walking back and forth across the width of the door to release one and then the other.
It is the object of the present invention to provide a retractable garage door screen installation with a more convenient latch release mechanism.
SUMMARY OF INVENTION
The above recited object of the invention and other objects which will be appreciated upon a reading of the following specification and claims, are achieved by providing two or more widely spaced latching mechanisms each comprised of a spring loaded plunger pin urged into an opening located to support the screen panel in a raised position juxtaposed behind the lower section of the garage door.
A pair of common operator levers are located at a remote control location, each connected by a cable to a respective plunger. The release levers are disposed close together so that a pinching motion exerted by a finger and thumb of one hand can simultaneously retract both of the plungers to release the screen panel and allow downward movement thereof on a series of slides. Thus, release can be effected at a single location along the width of the door to render operation quicker and easier.

DETAILED DESCRIPTION
In the following detailed description, certain specific terminology will be employed for the sake of clarity and a particular embodiment described in accordance with the requirements of 35 USC 112, but it is to be understood that the same is not intended to be limiting and should not be so construed inasmuch as the invention is capable of taking many forms and variations within the scope of the appended claims.
Referring to the drawings, a conventional sectional garage door
10
is shown having a screen installation
12
mounted thereon which includes a screen panel
14
of a length approximately matching the width of the garage door
10
, i.e., approximately sixteen feet for a standard two car garage, or eight feet for a standard single car garage door.
Such sectional garage doors move up and down vertically on tracks
18
at either end, the door sections
24
hinged together in the well known manner to accommodate the curvature of the tracks
18
as the door moves to a horizontal opened position over the garage opening.
The screen panel
14
may include an aluminum frame
16
having panels of screen material
20
installed therein.
Each section
24
of the door
10
is reinforced with a series of vertical stiffeners
22
, with mounting hinges
25
interconnecting adjacent sections
24
of the garage door
10
.
The screen panel
14
is approximately fifteen inches in height (which height can vary depending on the type of door) and may be stowed in the retracted position shown in FIG.
1
overlying the lowermost section
24
of the garage door
10
.
The screen panel
14
is mounted aligned with the bottom section
24
A of the door
10
, vertically slidable on bearing extension slides
26
(
FIG. 4
) of a type widely used for drawers, cabinet shelves, etc., attached to the screen panel frame
16
and to vertical box tubes
28
of aluminum plastic or other material attached to the stiffeners
22
of the garage door
10
.
As indicated in
FIG. 5
, the screen panel
14
may be constructed in two sections secured together with splice plates
56
, a central handle
58
secured thereto for manual lifting or lowering of the screen
14
.
A pair of latching mechanisms
29
A,
29
B respective include plastic brackets
30
A,
30
B respectively attached to the inside of the screen frame
16
adjacent respective spaced apart box beams
28
(FIG.
3
).
A latching pin
32
is mounted in each bracket
30
A,
30
B urged into an aligned opening
34
in a respective box tube
28
by a spring
36
acting on a flange
38
attached to each pin
32
A,
32
B.
An actuator cable
40
A,
40
B is attached to the opposite end of each pin
32
A,
32
B and extends to a central location whereat release elements comprised of outwardly angled levers
42
A,
42
B are pivotally mounted at
50
A,
50
B to the inside of the screen panel frame
16
. Each release lever
42
A,
42
B has an angled terminal portion
43
A,
43
B closely juxtaposed to each other (FIG.
5
).
This juxtaposition allows simultaneous squeezing of the levers
42
A,
42
B together with a finger and thumb of one hand, simultaneously retracting both pins
32
A,
32
B and causing a release of the screen frame
16
to allow the screen
14
to move down as the door
10
is raised. The outward angling insures sufficient travel to release the pins
32
A,
32
B. The screen
14
will cover the opening created by partial opening of the door
10
to an extent equal or less than the height of the screen panel
14
to provide ventilation while preventing entry of animals, insects, or windblown debris such as fallen leaves.
When the garage door
10
is lowered, the pins
32
A,
32
B will become aligned with the holes
34
A,
34
B and automatically be pushed back into a respective opening
34
by springs
36
A,
36
B to relatch the screen
14
in its stowed position, moving up and down with the door
10
.
The screen panel
14
and mounting is of a shallow depth such as to not interfere with the operation of an optical obstruction sensor
44
and target
46
.
FIG. 6
shows release levers
42
A,
42
B pivoted at
50
A,
50
B to the screen frame
16
. A locking strut
52
is connected to prevent the levers
42
A,
42
B from being squeezed together to prevent release of the screen
14
, held by a removable lock
54
. Upon removal of the lock
54
, the strut can pivot down on a screw
53
to allow the levers
42
A,
42
B to be squeezed together in the normal fashion.
