  "abstract": "A corner member for a window screen for joining framing members together at the corners, the corner member having a central body, first and second legs extending outwardly therefrom, a recess formed in the central body portion, and a plurality of resilient retaining members placed in the recess, each resilient retaining member having first and second retaining tabs which extend outwardly and which are designed to retain the screen in the window frame.",
  "claims": [
    "1. A corner member for use with hollow frame members to form a window screen comprising: a central body portion; first and second legs extending outwardly from said central body portion, said first and second legs having longitudinal axes which are mutually perpendicular with respect to each other, said legs each being sized to enter one of said frame members, said central body portion being sized larger than said legs to prevent entry thereof into said frame members; a recess formed in said central body portion; and a resilient retaining member in said recess, said resilient retaining member having first and second retaining tabs, said first retaining tab extending outwardly beyond said central body portion in a perpendicular direction with respect to said first leg, said second retaining tab extending outwardly beyond said central body portion in a perpendicular direction with respect to said second leg.",
    "2. The corner member of claim 1 wherein each of said legs has an upper wall, a bottom wall, and a side wall, said upper wall sloping inwardly and downwardly with respect to said lower wall.",
    "3. The corner member of claim 2 further including a plurality of ribs extending between said upper wall and said lower wall.",
    "4. The corner member of claim 1 wherein said central body portion has an upper wall and a lower wall, a flange extending outwardly from said upper wall on sides thereof to overlie said first and second retaining tabs.",
    "5. The corner member of claim 4 further including a diagonally extending rib extending between said upper wall and said lower wall within said recess.",
    "6. The corner member of claim 1 wherein each of said retaining tabs comprises an initial triangularly shaped portion extending outwardly from said resilient retaining member, and a retaining tab flange extending upwardly from an apex of said triangularly shaped portion.",
    "7. The corner member of claim 6 further including a plurality of flexible ribs extending outwardly from each of said retaining tab flanges.",
    "8. The corner member of claim 7 wherein said ribs each have a triangular configuration.",
    "9. The corner member of claim 2 wherein said central body portion has a top wall, said top wall having first and second segments, each of said first and second segments sloping inwardly and downwardly corresponding to said upper wall of an adjacent leg.",
    "10. A window screen comprising: a top frame member; a bottom frame member; a pair of side frame members, said frame members being hollow and being secured at corners thereof by a corner member, said corner member comprising a central body portion; first and second legs extending outwardly from said central body portion, said first and second legs having longitudinal axes which are mutually perpendicular with respect to each other, said legs extending interiorly of said frame member with said central body portion being exterior of said frame members; a recess formed in the central body portion; and a resilient retaining member in the recess, said resilient retaining member having first and second retaining tabs, said first retaining tab extending outwardly in a perpendicular direction with respect to the first leg, said second retaining member tab extending outwardly in a perpendicular direction with respect to said second leg, each of said retaining tabs extending beyond said central body portion to permit engagement with a window frame.",
    "11. The corner member of claim 1 wherein said resilient retaining member is formed of an elastomeric material.",
    "12. The window screen of claim 10 wherein said resilient retaining member is an elastomeric material."

  "description_excerpt": "The present invention relates to screens such as are used in a building structure and more particularly, relates to a corner member used in the manufacture or assembly of screens.\n\nIn modern day windows, a screen is usually provided as part of original window equipment. The screen member must be light-weight and easily removable such that access may be had to the glass portion of the window. Traditionally, the screen is formed by a top frame member, a bottom frame member, and two side frame members. The frame members are secured together at the corners by suitable means. In some windows, a corner member is used to join the frame members. The advantage of forming the screens from the frame members and joining at their corners is the ease with which different size screens may be formed. As there are no standards for window size, the screens have to be custom designed for each window. The screen is frequently held in place by means of metallic springs which sit in channels formed in the window. The springs on one side of the screen push the screen into an opposing channel. Alternatively, a pin like element may be provided in the sides of the screen with the pins being movable to sit within an aperture formed in the window frame.\n\nWhile both of the above methods function satisfactorily, they do require certain manufacturing adjustments and, in the case of the pin like elements, can be somewhat costly to manufacture.\n\nIt is an object of the present invention to provide a corner member for fabricating screens and which corner member also includes means for securing the screen in place.",
