1. Field of the Invention
This invention relates to door reinforcements, and in particular to an apparatus and method to reinforce doors against windstorm.
2. Background of the Invention
Windstorms cause huge amounts of damage to buildings every year. These windstorms may be hurricanes, tornadoes, typhoons, or other meteorological phenomena which give rise to winds sufficiently high so as to endanger structures.
An important strategy in the fight against windstorm damage is to prevent breach of the building itself. Breaches may occur through windows or doors, or other vulnerable building feature, and allow wind to enter the structure. If wind forces its way into a structure, it can cause high enough internal building pressure so as to literally blow the roof off the building. Another possibility is that the high pressure inside a building caused by a building breach can blow out windows or building doors.
The loss of part or all of a roof, doors, and/or windows creates a path for the entry of rain, which may be driven virtually horizontally due to the high winds associated with windstorms. This rain can cause extensive water damage in the interior of a structure, and is an undesirable side effect of the initial breach. Thus, while an initial breach through a door or window may be relatively minor, it can be the first link in a chain of events which culminates in catastrophic damage to the structure itself, including but riot limited to extensive water damage, loss of roof, and eventually, even building collapse.
Therefore, it would be desirable to provide an apparatus and method to reinforce doors against windstorm, whereby an initial breach through the door, along with attendant undesirable side effects, may be avoided.
Accordingly, it is an object of the present invention to provide an apparatus and method to reinforce doors against windstorm which mounts to existing door hardware. Design features allowing this object to be accomplished include a bar bracket with ears spaced to admit an existing hinge, each ear having an ear bore sized to admit a bracket fastener sized to fit through the existing hinge. Advantages associated with the accomplishment of this object include ease of installation and avoidance of the necessity of making additional, unsightly holes in the door.
It is another object of the present invention to provide an apparatus and method to reinforce doors against windstorm which installs quickly and easily to existing door installations. Design features allowing this object to be accomplished include a bar bracket with ears spaced to admit an existing hinge, each ear having an ear bore sized to admit a bracket fastener sized to fit through the existing hinge, and a bar sized to fit into a bar aperture in the bar bracket. Benefits associated with the accomplishment of this object include saved time and cost in installation of the apparatus to reinforce doors against windstorm.
It is another object of the present invention to provide an apparatus and method to reinforce doors against windstorm which is simple to install. Method steps include removing a hinge pin from an existing hinge, positioning a bar bracket on the hinge such that the hinge is disposed between a pair of ears, inserting a bar bracket fastener through the ear bores and the hinge bore, inserting a bar through at least one bar aperture, and shimming the bar in place. Benefits associated with the accomplishment of this object include saved time and cost in installation of the apparatus to reinforce doors against windstorm.
It is yet another object of this invention to provide an apparatus and method to reinforce doors against windstorm which is simple and inexpensive. Design features allowing this object to be achieved include the use of components made of readily available materials, and the use of off-the-shelf components. Benefits associated with reaching this objective include reduced cost, and hence increased availability.
The invention, together with the other objects, features, aspects and advantages thereof will be more clearly understood from the following in conjunction with the accompanying drawings.
Eight sheets of drawings are provided. Sheet one contains
During installation, existing hinge pin 22 is removed from an existing hinge 10 upon which a bar bracket 6 is to be installed, as may be observed in
As may be noted in
Next, as illustrated in
The above steps are repeated to install all bar brackets 6 which are desired to be installed on the existing double doors. Then bar 4 is inserted through bar apertures 18 in bar brackets 6, as depicted in
Thus, the instant method to reinforce doors against windstorm comprises the steps of:
A. Providing at least one bar bracket 6 having a bar aperture 18 and at least one pair of opposed ears 14, and an ear bore 16 in each said ear 14;
B. Removing a hinge pin 22 from a hinge bore 9 in an existing hinge 10 on a door 8, upon which said bar bracket 6 is to be installed;
C. Positioning said bar bracket 6 on said hinge 10 such that said hinge 10 is disposed between said opposed ears 14, and said ear bores 16 and said hinge bore 9 are co-axial;
D. Inserting a bracket fastener 26 through said ear bores 16 and said hinge bore 9;
E. Optionally installing a nut on a protruding end of said bracket fastener 26;
F. Repeating steps A-E until all desired bar brackets 6 are installed;
G. Inserting a bar 4 through at least one said bar aperture 18;
H. Driving at least one shim 12 between said bar 4 and at least one said door 8 and/or an adjacent wall 11; and
I. Optionally fastening at least one said shim 12 to said bar 4 with a shim fastener 34.
A bar bracket 6 is then installed on hinge leaf 36 by positioning the bar bracket 6 on hinge leaf 36 such that the hinge leaf 36 is disposed between opposed ears 14 on the bar bracket 6, and the ear bores 16 and the hinge leaf bore 38 are co-axial. Then a bar bracket fastener 26 is inserted through the ear bores 16 and the hinge leaf bore 38, and a nut is optionally installed on a protruding end of the bar bracket fastener 26.
Then bar 4 is inserted through the bar apertures 18 and shimmed in place using shims 12, and optionally shim fasteners 34.
Thus, the instant method to reinforce a single door against windstorm comprises the steps of:
A. Providing an apparatus to reinforce doors against windstorm comprising at least one bar bracket 6 having a bar aperture 18 and at least one pair of opposed ears 14, and an ear bore 16 in each said ear 14;
B. Removing a hinge pin 22 from a hinge bore 9 in an existing hinge 10 on a door 8, upon which said bar bracket 6 is to be installed;
C. Positioning said bar bracket 6 on said hinge 10 such that said hinge 10 is disposed between said opposed ears 14, and said ear bores 16 and said hinge bore 9 are co-axial;
D. Inserting a bar bracket fastener 26 through said ear bores 16 and said hinge bore 9;
E. Optionally installing a nut on a protruding end of said bar bracket fastener 26;
F. Inserting a bar 4 through said bar aperture 18;
G. Driving at least one shim 12 between said bar 4 and at least one said door 8 and/or an adjacent wall 11; and
H. Optionally fastening at least one said shim 12 to said bar 4 with a shim fastener 34.
The instant method to reinforce a single door against windstorm may comprises the further steps of:
I. Providing a hinge leaf 36 having a hinge leaf wing 40 and a hinge leaf bore 38;
J. Attaching said hinge leaf 36 to a door frame opposite the bar bracket 6 installed on said hinge 10;
K. Positioning a bar bracket 6 on said hinge leaf 36 such that said hinge leaf 36 is disposed between said opposed ears 14, and said ear bores 16 and said hinge leaf bore 38 are co-axial;
L. Inserting a bar bracket fastener 26 through said ear bores 16 and said hinge leaf bore 38;
M. Optionally installing a nut on a protruding end of said bar bracket fastener 26; and
N. Inserting said bar 4 through said bar aperture 18 in said bar bracket 6 installed on said hinge leaf 36.
As described above in relation to all method embodiments to install apparatus to reinforce doors against windstorm 2, bar 4 is inserted through bar aperture(s) 18 after bar bracket(s) 6 are installed on existing hinge(s) 10 and/or hinge leaf 36. If the physical space available prohibits this procedure, then bar bracket(s) 6 may be slid onto bar 4 prior to installing bar bracket(s) 6 on existing hinge(s) 10 and/or hinge leaf 36.
Apparatus to reinforce doors against windstorm 2 is removed by simply reversing the above steps, including re-installation of hinge pin(s) 22.
In the preferred embodiment, bar bracket 6 was made of metal, synthetic, or other appropriate material. Bracket fastener 26 and shim fastener 34 were off-the-self fasteners such as screws. Shims 12 were conventional prism-shaped shims. Hinge leaf 36 was half of a standard, off-the-shelf hinge.
While a preferred embodiment of the invention has been illustrated herein, it is to be understood that changes and variations may be made by those skilled in the art without departing from the spirit of the appending claims.
