The apparatus includes a mounting frame formed of extruded profiles secured to the window frame, and a security frame formed of extruded profiles extending about a perimeter of the auxiliary panel member. Protrusions and a pivotal lock member on the security frame are selectively received within corresponding channels on the mounting frame to selectively fix the security frame relative to the mounting frame. The security frame includes a perimeter slot that receives the edge of a variety of different auxiliary panel members including additional panes of plastic or glass, or security mesh, or soundproofing barriers and the like.
Description
WINDOW SECURITY APPARATUS
FIELD OF THE INVENTION
The present invention relates to a security apparatus for mounting onto a window, for example by being fixedly secured to an exterior surface of the window frame of the window, to support an auxiliary panel, for example a security barrier or a soundproofing barrier, alongside the panes of the window.
BACKGROUND
There are many situations where windows in buildings require protection from damage, for example due to proximity to sporting equipment or other types of equipment that are known to accidentally cause damage to windows, or due to intentional breakage by vandals or persons seeking unauthorized entry into a building.
In this instance, it is known to support various types of security devices over the exterior of the window, including metal bars and the like. In some instances, the security devices are merely fastened to the exterior of the window, however, the fasteners are either difficult to remove when maintenance of the window is desired, or in the alternative the fasteners can be readily defeated by unauthorized persons. In other instances, hardware is provided for using padlocks to secure a security device over a window;
however, known hardware for securing padlocks typically have an unattractive and unfinished appearance at the exterior of the building.
Among the prior art, United States patents 4,478,002 by English and 6,167,656 by Devlin disclose security window panels; however, in each instance the panels are not well suited for mounting at the exterior of a building such that the devices serve primarily to restrict unauthorized entry into the building but do not provide protection against damage to the glass panes of the existing window.

7 DETAILED DESCRIPTION
Referring to the accompanying figures there is illustrated a window security apparatus generally indicated by reference numeral 10. The apparatus 10 is particularly suited for use with a window 12 in a building to extend over an exterior side of the window to protect and/or restrict access to the window.
The window includes a window frame 14 comprising a plurality of perimeter members connected to one another about a full perimeter of the window. The perimeters members forming the window frame may be formed of wood, metal or plastic. In each instance, the perimeter members of the window frame support the edges of one or more transparent window panes 16 formed of glass or plastic material.
An exterior side of each perimeter member of the window frame, at an exterior of the building, comprises an exterior surface lying in a common plane with the exterior surfaces of the other perimeter members such that the exterior surfaces commonly define an exterior face of the window frame and of the window.
The apparatus 10 generally comprises a mounting frame 18 for mounting in fixed relation onto the exterior face of the window and a security frame 20 which supports an auxiliary panel member 22 therein such that the auxiliary panel member is releasably supported together with the security frame relative to the mounting frame and the window frame upon which the mounting frame is mounted.
The mounting frame 18 is assembled from a plurality of mounting members 24 in which each mounting member comprises an extruded profile. In the illustrated example, when the window is rectangular, a set of four mounting members 24 are provided with 45 beveled ends so that the ends of each mounting member are coupled to ends of adjacent mounting members at a mitered connection to assemble the mounting members in series with one another about the full perimeter of the window Date Recue/Date Received 2020-04-22

The window includes a window frame 14 comprising a plurality of perimeter members connected to one another about a full perimeter of the window. The perimeters members forming the window frame may be formed of wood, metal or plastic. In each instance, the perimeter members of the window frame support the edges of one or more transparent window panes 16 formed of glass or plastic material.
An exterior side of each perimeter member of the window frame, at an exterior of the building, comprises an exterior surface lying in a common plane with the exterior surfaces of the other perimeter members such that the exterior surfaces commonly define an exterior face of the window frame and of the window.
The apparatus 10 generally comprises a mounting frame 18 for mounting in fixed relation onto the exterior face of the window and a security frame 20 which supports an auxiliary panel member 22 therein such that the auxiliary panel member is releasably supported together with the security frame relative to the mounting frame and the window frame upon which the mounting frame is mounted.
The mounting frame 18 is assembled from a plurality of mounting members 24 in which each mounting member comprises an extruded profile. In the illustrated example, when the window is rectangular, a set of four mounting members 24 are provided with 45 beveled ends so that the ends of each mounting member are coupled to ends of adjacent mounting members at a mitered connection to assemble the mounting members in series with one another about the full perimeter of the window Date Recue/Date Received 2020-04-22
8 frame so as to define a rectangular shape of the mounting frame.
Similarly, the security frame is assembled from a plurality of frame members 26 in which each frame member comprises an extruded profile. In the illustrated embodiment, the extruded profile of the frame members of the security frame and the extruded profile of the mounting members of the mounting frame are identical to one another so as to be produced from the same extrusion mold.
Similarly to the mounting frame, the frame members of the security frame according to the illustrated embodiment are assembled to match the rectangular shape of the window such that a set of four frame members 26 are provided with 45 beveled ends so that the ends of each frame member are coupled to the ends of adjacent frame members at a mitered connection. The frame members are thus assembled in series with one another about the full perimeter of the window frame so as to define a rectangular shape of the security frame.
The security frame is assembled about the perimeter of the auxiliary panel member such that a perimeter edge of the auxiliary panel member is partly received internally within the mounting frame about the full perimeter thereof. A
remaining exposed surface area of the auxiliary panel member which is not received within the security frame and which spans the interior opening of the security frame is arranged to have dimensions which are approximately equal to the exposed area of the window panes of the window. The interior dimensions of the security frame, that is the dimensions of the interior opening of the security frame, corresponds approximately to the dimensions of the interior opening of the window frame supporting the window panes therein.
The mounting frame is sized to be slightly larger in dimensions than the security frame such that an interior dimension of a main body portion of the mounting Date Recue/Date Received 2020-04-22
Similarly, the security frame is assembled from a plurality of frame members 26 in which each frame member comprises an extruded profile. In the illustrated embodiment, the extruded profile of the frame members of the security frame and the extruded profile of the mounting members of the mounting frame are identical to one another so as to be produced from the same extrusion mold.
Similarly to the mounting frame, the frame members of the security frame according to the illustrated embodiment are assembled to match the rectangular shape of the window such that a set of four frame members 26 are provided with 45 beveled ends so that the ends of each frame member are coupled to the ends of adjacent frame members at a mitered connection. The frame members are thus assembled in series with one another about the full perimeter of the window frame so as to define a rectangular shape of the security frame.
The security frame is assembled about the perimeter of the auxiliary panel member such that a perimeter edge of the auxiliary panel member is partly received internally within the mounting frame about the full perimeter thereof. A
remaining exposed surface area of the auxiliary panel member which is not received within the security frame and which spans the interior opening of the security frame is arranged to have dimensions which are approximately equal to the exposed area of the window panes of the window. The interior dimensions of the security frame, that is the dimensions of the interior opening of the security frame, corresponds approximately to the dimensions of the interior opening of the window frame supporting the window panes therein.
The mounting frame is sized to be slightly larger in dimensions than the security frame such that an interior dimension of a main body portion of the mounting Date Recue/Date Received 2020-04-22
9 members 24 about the interior opening that is surrounded by the mounting frame corresponds approximately to an outer dimension of a main body portion of the frame members 26 of the security frame about the interior opening of the security frame.
The extruded profile forming each mounting member 24 of the mounting frame and each frame member 26 of the security frame has a main body portion which is generally rectangular in shape. An overall width of the main body portion is defined between a first mounting face 30 and an opposing second face 32 which are parallel and spaced apart from one another.
A protruding flange 34 is joined to the main body portion 28 to protrude outwardly beyond the rectangular boundary of the main body portion. The protruding flange 34 is oriented to project perpendicularly to the first mounting face 30 outward of the main body portion from one of the side edges of the first mounting face 30.
The main body portion 28 also includes an overall depth in a direction perpendicular to the width which extends between a proximal face 36 which is substantially coplanar with the protruding flange 34 so as to be in close proximity to the protruding flange, and a distal face 38 at an opposing side of the main body portion so as to lie parallel and spaced apart from the flange 34 at the proximal face 36.
