BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a storm and guard shutter assembly for building external openings and, more particularly, to a window and door shutter for both guarding as a security barrier to deter an intruder from entering the building and storm shielding as a storm barrier to protect the window and door from strong winds and wind-borne debris, which are accompanied by a quick out of fire, flood, or other emergency window and door escape mechanism.
2. Description of the Prior Art
Both window and door guards are conventionally used to prevent unauthorized entry through window and door openings. Storm shutters are needed to protect a building from wind damage by flying debris during hurricanes or cyclones. Known prior art includes U.S. Pat. Nos. 6,205,713 and 6,293,059 which are made up of heavy plywood panels; U.S. Pat. Nos. 5,487,244, 5,596,849, 5,768,833, 5,996,292, and 6,209,263 which are made up of corrugated aluminum or still panels; U.S. Pat. Nos. 5,457,921 and 6,470,639 which are made up of corrugated and solid translucent plastic panels, respectively; U.S. Pat. No. 4,416,084 which is made up of protector bars extending across the window. The above mentioned permanently installed window and door guards, as well as a variety of others not mentioned here and hurricane shutters, have a number of drawbacks. Among them, the most important is that in the event of fire or other emergency, it is impossible for someone inside of the building to leave the building through the permanently guarded or fastened from outside window or door. The ideal emergency unlocking mechanism for a window guard should be easily unlocked in the event of an emergency, but when it is locked, difficult to remove, thus providing a high degree of security. However, particularly for hurricane shutters, it would also be desirable in some situations to have an additional option that, in the case of emergency, allows easy unlocking from both inside by a building occupant and outside by emergency personnel.
U.S. Pat. No. 4,333,271 to DePaolo et al. discloses hurricane panels mounted on the outer side of the opening to protect the opening against the effects of winds and atmospheric conditions. A security means is installed at the outer side of the panel to preserve the installation against unauthorized removal of the panel for gaining entrance to the premises. However, the security means is secured from the inner side of the panel from inside of the building, making the release of the panel from inside in the case of emergency impossible.
Most of prior art patents dealing with window protective devices equipped with emergency exit options are directed toward burglar guards. U.S. Pat. No. 2,222,866 to Graig, discloses burglar guards mounted on the outer side of the opening to protect the opening of unoccupied building against breakage by vandals or the theft of property inside of the building. Nevertheless, the construction allows its dismounting from inside, such option has never been considered in the disclosure. In addition, emergency quick dismounting of such construction will be very difficult to perform by an untrained person.
U.S. Pat. No. 4,562,666 to Young, Ill. discloses a burglar guard for windows and doors, which is constructed of unbreakable, bullet-resistant, transparent sheet material, such as polycarbonate or Lexan plastic which is installed on the interior of the building window openings. Such cover can be quickly removed from inside in the case of emergency, however, it does not protect against breakage of windows by both vandals and hurricane/tornado wind and debris.
Publication No. US 2006/0283131 and U.S. Pat. No. 7,438,336 to Wolf and Clark disclose a hurricane shutter escape mechanism for allowing removal of a conventional hurricane shutter from a window or door of a structure in the event of emergency. It can be activated from both inside and outside of the building opening. However, in this construction, the spring-actuated panel fastener is installed on each hurricane shutter panel. Therefore, if a person escaping from inside of the building or a rescuer from the outside wants to gain access through the opening, the escaper/rescuer has to manually remove a sufficient number of the spring-actuated panel fasteners, which may be difficult, especially in the case of panic. The disclosed rope mechanism for releasing an array of actuating arms appears to be unreliable. With the exception of this reference, applicant is unaware of another presently available apparatus and structure for storm protection which is equipped with a quick emergency escape mechanism that can be activated from both inside and outside of the building.
Furthermore, applicant is unaware any hurricane shutter escape mechanism which allows removal of a conventional hurricane shutter from a window or door of a structure in the event of emergency which can be activated from both inside and outside of the building opening while keeping a security means installed at the outer side of the panel to preserve the installation against unauthorized removal of the panel to gain entrance to the premises.
In addition, even though a conventional hurricane shutter is efficient in the protection of a building opening from the destructive force of storm systems, such as hurricanes, applicant is unaware of presently available designs capable of providing both an easy escape mechanism in the case of emergency and an enhanced security of the building against an unwanted intrusion.
Moreover, applicant is unaware of presently available hurricane shutter systems providing weather-tight and/or water-tight seals of the shutter as well as additional thermal insulation qualities while maintaining a quick emergency escape capability and enhanced security of the building against an unwanted intrusion.
SUMMARY OF THE INVENTION
The main object of the present invention is to provide a quick fire or other emergency escape mechanism for a shutter protecting a window, door, or other opening, which will overcome the shortcomings of the prior art devices.
Another object is to provide a quick fire or other emergency escape mechanism for a hurricane protective shutter which can be activated easily and quickly by people from inside of the building.
An additional object is to provide a quick fire or other emergency escape mechanism for a hurricane protective shutter which can be activated easily and quickly by both people within the building and by emergency personnel outside of the building in the case of incapacity of the people inside of the building.
A further object is to provide a quick fire or another emergency escape mechanism for a security shutter which is normally in a locked position and also maintain a storm protective utility protecting window, door, or other openings of a building which can be activated easily and quickly by people from inside the building. The object is to prevent entry through the window, door, or another opening to reduce burglaries when the building is empty or unoccupied during an evacuation period and a post-evacuation period when people have returned back home but the area is still at the risk of a criminal entry.
A still further object is to provide weather-tight and/or water-tight seals of the shutter against its adjacent wall allowing a variety of marine and coastal applications to fulfill requirements that the closures be capable of sealing interiors from exposure to salt water while maintaining a quick emergency escape capability.
Still another object is to provide additional thermal insulation qualities while upgrading the security of a building against an unwanted intrusion as well as providing a quick emergency escape capability.
A still further object is to provide a quick fire or other emergency escape mechanism for a shutter which is reliable and easy to install and use.
A yet further object is to provide a quick fire or other emergency escape mechanism for a shutter which is cost effective and uses conventionally available construction and manufacturing materials without significant investment for production of non-standard parts and equipment.
Further aspects and advantages of this invention will be evident from the following detailed description, which proceeds with reference to the accompanying drawings.

It can be achieved by maintaining a proper geometry relationship between the shape and dimensions of the assembly that includes position of pivot studs 24 and distance L between them relative to the geometry of the removable latch member 12-T as well as the shape of the fork-lift flange. In fact, the tolerance TOL should be kept by such a way that allows maintaining one side of the window opening assembly in a locked and the other in the unlocked positions. It can be achieved by a proper procedure for assembling, which comprises the steps of
- coupling the wall 19-T and shutter 20-T engaging members of the header member by an auxiliary screws or a sticky tape,
- fastening the wall engaging member 19-T to the inner top surface of the opening using screws 6 keeping in mind that the surface of the shutter engaging member 20-T facing the shutter is positioned within the flat surface formed by outer edges of the opening,
- assembling side members that includes mounting a fork-lift flange 23 to the corresponding latch slide 12 side member followed by latching one of the side members in a locked and the other in unlocked positions,
- inserting pivot studs 24 into the slots 23-S of corresponding fork-lift flanges and moving the assembly for mounting to the inner side wall of the opening,
- fastening by screws 6 to the wall the locked wall side member 12 maintaining the minimum tolerance TOL-min between the top corner of the removable top member 12_T and the bottom of both the wall 19-T and shutter 20-T engaging members of the top member while keeping the other side member in the lower position,
- switching the positions of the locked and unlocked side members and fastening by screws 6 to the wall the locked side member while maintaining the minimum tolerance between the top corner of the removable top member 12-T and the bottom of both the wall and shutter engaging members of the top member,
- assembling the bottom, footer member, by latching wall 19-B and shutter 20-B members in a locked position,
- fastening the wall engaging member 19-B to the inner bottom surface of the opening using screws 6 keeping in mind that the surface of the shutter engaging member 20-B facing shutter is positioned within the flat surface formed by outer edges of the opening,
- making a template with the position for the holes in the shutter panel for the whole building opening,
- positioning the template on the shutter 3 panel and making proper holes,
- unlocking all shutter engaging members and removing from the assemblies,
- fastening them in the proper position to the shutter panel,
- engaging the shutter assembly into the window opening and latching first top and side members by sliding left and right latching members towards the top latch member,
- locking left and right members by inserting a pin into aligned apertures of engaging and latching members, and
- sliding and locking the bottom latch member.

Another embodiment is shown in FIGS. 19-24B. In this embodiment, a guard shutter assembly with weather-tight and/or water-tight sealing around the window/door opening accompanied by additional thermal insulation qualities, burglary protection, and quick emergency escape mechanism is illustrated. The closure shown in FIG. 19 is mounted over all four sides of the window/door opening and comprises:
- a shutter panel 3 equipped with a sealing gasket 27 around the periphery of the shutter panel,
- a wall header member 19-T, two wall side members 19-L and 19-R, and wall footer member 19-B are engaged with the corresponding engaging shutter members 20-T, 20-L, 20-R, and 20-B and capable to be shifted toward each other while the latch member 12 is slid from open/unlocked to the fastened/locked position providing compression to the seal 27,
- side slide members with fork-lift flanges 23 having horizontal slots 23-S on each of their top sides for lifting and latching the top latch member 12-T and keeping it in a aligned position allowing to slide across the engaging parts of the side member, thus providing compression to the seal 27,
- a footer member that is equipped with an engaging sliding member 12-B that is slid along the length of a latching member, thus providing compression to the seal 27.
The guard shutter assembly with weather-tight and/or water-tight sealing around the window/door opening is constructed of different flat sheet material which is dependent of the application. Bullet-resistant transparent/translucent materials, such as polycarbonate or Lexan plastic, are especially suitable in weather-tight and water-tight applications
FIG. 20A is a cross-sectional view of the top latching mechanism in an unlocked/unsealed position, which is taken along a line D-D of FIG. 19.
FIG. 20B is a cross-sectional view of the top latching mechanism in a locked/sealed position which is taken along a line D-D of FIG. 19.
FIG. 20C is a cross-sectional view of the top latching mechanism installed on an angled base 17 which is mounted on the top sill of the window/door opening that is not straight against an outside wall of the building in an unlocked/unsealed position, which is taken along a line D-D of FIG. 19.
FIG. 20D is a cross-sectional view of the top latching mechanism as of FIG. 20C in a locked/sealed position, which is taken along a line D-D of FIG. 19.
FIG. 20E is a prospective view of a window/door opening with angled bases 17 on all sides of the opening; which are mounted on the window/door sills and sides that are not straight against an outside wall of the building, for mounting the latching assemblies as well as for better sealing of the window opening in a locked position, which also can function as a decorative frame around the opening.
FIG. 21A is a cross-sectional view of the side, right, latching mechanism in an unlocked/unsealed position, which is taken along line E-E of FIG. 19.
FIG. 21B is a cross-sectional view of the side, right, latching mechanism in an unlocked/unsealed position, which is taken along line F-F of FIG. 21A.
FIG. 22A is a cross-sectional view of the side, right, latching mechanism in a locked/sealed position, which is taken along a line E-E of FIG. 19.
FIG. 22B is a cross-sectional view of the side, right, latching mechanism in a locked/sealed position, which is taken along a line F-F of FIG. 22A.
Sliding the latch member results in the seal compression and requires applying an additional force, which may be significant for an ordinary person. Therefore, in the preferred embodiment, decrease of applied force by inhabitants has been achieved by application of both a latch gear assembly, shown in FIGS. 23A-23B, and a latch cam gear assembly, shown in FIGS. 24A-24B.
