1. Technical Field
The present disclosure relates to windows for stationary structures such as buildings and homes. More particularly, the present disclosure relates to security windows having impact-resistant properties.
2. Background of Related Art
Over the years, security windows have been developed for a number of purposes. Some security windows are specifically designed to impede forced entry or penetration by projectiles. Other security windows are capable of resisting hurricane force winds. Regardless of its specific objective, security windows usually provide a higher level of protection than regular windows.
A conventional security window includes a framework supporting reinforced panes. Typically, glass and plastic layers form the reinforced panes. Some of the reinforced panes have at least one plastic reinforcing layer and a number of glass layers. One type of security window uses a special laminate composed of a polycarbonate sheet, layers of tertiary butyl styrene resin, and at least one glass sheet. One layer of tertiary butyl styrene resin is adhered to each opposing side of the polycarbonate sheet. The glass sheets, in turn, are bonded to each layer of tertiary butyl styrene resin. A highly flexible silicone adhesive may be utilized to glue the laminate to a window frame.
Another kind of security window offers protection against incoming projectiles by utilizing a window pane with a gap and internal chambers. This window pane includes a frame composed of metallic profiled sections. The metallic profiled sections delimit the gap, which has a stepped configuration. In use, a projectile moving toward the window pane may enter the gap, but it is promptly deflected by the stepped configuration of the gap. The window pane also has internal chambers delimited by inclined surfaces that extend at an acute angle with respect to a side of the window pane. When a projectile penetrates any of these internal chambers, it is deflected upon contacting the inclined surfaces delimiting the respective internal chamber. After the projectile has been deflected, other parts of the window pane stop the penetrating projectile.
In addition to the window designs described above, many other designs have been developed throughout the years. Nonetheless, improvements are always possible.
The present disclosure relates to a security window for shielding a secured space from forceful attacks. An embodiment of the presently disclosed security window includes a fixed lateral profile, a pane, a pane profile movably mounted on the fixed lateral profile, and a locking mechanism is configured to secure the pane profile to the fixed lateral profile. The pane profile supports the pane and is adapted to move the pane between open and closed positions. The locking mechanism has locked and unlocked positions and includes a movable profile adapted to slide longitudinally and transversely with respect to the fixed lateral profile. The movable profile is positioned between the fixed lateral profile and the pane profile when the locking mechanism is in the locked position. When the locking mechanism is in the unlocked position, the movable profile is located inside the pane profile.
In an alternative embodiment, the security window includes a first fixed lateral profile, a second fixed lateral profile, a pane, a pane profile including first and second columns, and a a plurality of locking mechanisms operatively associated with the first and second columns of the pane profile. The first and second columns are movably mounted on the respective first and second fixed lateral profiles. The pane profile encloses the pane and is adapted to move the pane between open and closed position. Each locking mechanism has locked and unlocked positions. Further, each locking mechanism is configured to secure the pane profile to the first and second fixed lateral profiles and includes a movable profile adapted to slide longitudinally and transversely with respect to the fixed lateral profile. The movable profile is positioned between the pane profile and at least one of the first and second fixed lateral profiles when locking mechanism is in the locked position. When the locking mechanism is in the unlocked position, the movable profile is located inside the pane profile.

Header 204 additionally includes a connecting panel 216 extending between first and second ends 204a, 204b and transversely interconnecting an inner panel 218 and an outer panel 220. Inner panel 218 is located on an inner portion 204c of header 204, whereas outer panel 220 is positioned on an outer portion 204d of header 204. Inner panel 218 covers a portion of each fixed lateral profile 202, thereby inhibiting the penetration of fluids, projectiles, and other foreign objects through security window 200. As seen in
Sill 206 has first and second ends 206a, 206b operatively attached to respective fixed lateral profiles 202. In addition, sill 206 includes a connecting panel 222 extending between first and second ends 206a, 206b and interconnecting an inner panel 224 and an outer panel 226. Outer panel 226 is located on an outer portion 206c of sill 206, and inner panel 224 is positioned on an inner portion 206d of sill 206. Inner panel 224 covers a portion of each fixed lateral profile 202, thus hindering the penetration of fluids, projectiles, and other foreign objects through security window 200.
As discussed hereinabove, security window 200 further includes a couple of fixed lateral profiles 202 placed at opposite sides thereof. Each fixed lateral profile 202 is operatively attached to header 204 and sill 206. As illustrated in
First pane profile 208 supports a first pane 212 and a second pane profile 210 supports a second pane 214. As seen in
