Definitions

  • This invention relates to a nodal assembly, particularly a corner assembly, for a peripheral frame which can be removably mounted on an architectural opening.
  • This invention quite particularly relates to a comer assembly for the frame of an insect screen for a window opening.
  • a nodal assembly for connecting at least two adjacent frame members of a perimeter frame, the nodal element comprising:
  • the first and second sides of the central portion are laterally opposite sides, preferably front and rear sides; the cavity in the first leg is substantially parallel to the first leg; one end of the cavity is in communication with one end of a channel in the central portion; and the other end of the channel is in communication with the opening in the central portion.
  • the retainer comprises:
  • a perimeter frame comprising:
  • Figures 1-13 schematically show one embodiment of a rectangular perimeter frame, generally 1, of this invention for an architectural opening, such as a window.
  • the perimeter frame 1 comprises first, second, third and fourth elongate frame members 3, 5, 7 and 9, the ends of which are connected to each other by first, second, third and fourth, nodal or corner assemblies 11, 13, 15 and 17, respectively, of this invention.
  • a sheet-like panel member 19, such as an insect screen, is attached in a conventional manner to the frame members 3, 5, 7 and 9 to cover an area surrounded by the perimeter frame 1.
  • Extending from the rear of each corner assembly 11, 13, 15 and 17 is a hook-shaped retainer 21, 23, 25 and 27, respectively, each having a hook-shaped first end part 22, 24, 26 and 28, respectively, which will be described below in relation to Figures 8-13.
  • Figure 3 shows a first type of window frame 29A hingedly carrying a pane frame 31A.
  • the window frame 29A has only a shallow thickness 33A which is common to metal window frames.
  • the hinged pane frame 31A can be made of metal, wood or plastic and contains a glass pane 35A.
  • each retainer 21, 23 , 25 and 27 need only extend rearwardly from the perimeter frame 1 and its corner assembly 11, 13, 15 and 17 by the rearward thickness 33A of the adjacent inner facing side 36A of the Figure 3-type window frame 29A. If the retainers 21, 23, 25 and 27 have sufficiently thin hook-shaped end parts 22, 24, 26 and 28, as is shown in Figure 3, they do not interfere with the closure of the pane frame 31A. With this arrangement, the sheet-like panel 19 in the perimeter frame 1 can remain in position when the pane frame 31A is closed.
  • Figure 4 shows a second type of window frame 29B hingedly carrying a pane frame 31B that contains a glass pane 35B.
  • the window frame 29B has a larger thickness 33B than does the window frame 29A of Figure 3.
  • the window frame 29B can be made of wood or plastic, and the hinged pane frame 31B can be made of metal, wood or plastic.
  • the hook-shaped end parts 22, 24, 26 and 28 of the retainer hooks 21, 23, 25 and 27 extend rearwardly from the perimeter frame 1 and its corner assemblies 11, 13, 15 and 17 by the substantial rearward thickness 33B of the respective adjacent inner facing sides 36B of the Figure 4-type window frame 29A.
  • the retainers 21, 23 ,25 and 27 and the corner assemblies 11, 13, 15 and 17 are preferably constructed in accordance with this invention to hold the perimeter frame 1 in place on the relatively thick window frame 31B of Figure 4, as well as the relatively thin window frame 31A of Figure 3. If the retainers 21, 23, 25 and 27 have sufficiently thin hook-shaped end parts 22, 24, 26 and 28, as is shown in Figure 4, they do not interfere with the closure of the pane frame 31B. With this arrangement, the sheet-like panel 19 in the perimeter frame 1 can remain in position when the pane frame 31B is closed.
  • the perimeter frame may conveniently be hung on the outside of an inwardly opening window or on the inside of an outwardly opening window.
  • the retainers 21, 23, 25 and 27 are preferably made from a relatively strong and durable metal or plastic, especially steel, particularly a conventional spring steel.
  • the upper retainers 21 and 27 can, if desired, be made from a somewhat more flexible material than the lower retainers 23 and 25. However, for ease of stocking retainers 21 - 27, it may be preferable to use identical upper retainers 21 and 27 and lower retainers 23 and 25 in the perimeter frame 1.
  • a spline 41 is preferably provided in a groove 42 formed in the inner facing side of each of the frame members 3, 5, 7 and 9 to hold the sheet-like panel 19 in the perimeter frame 1 of this invention.
  • Figures 5, 6 and 7 show the steps for installing the perimeter frame 1 in a window frame 29.
  • the upper retainers 21 and 27 (27 not shown in Figures 5-7), with their upwardly extending, hook-shaped end parts 22 and 28, are pulled outwardly of their respective upper corner assemblies 11 and 17by a distance corresponding to the thickness of the frame 29.
  • the upper retainers 21 and 27 are then urged against the upper jamb 43 of the window opening 29 and deflected downwardly to a distance "a" above the bottom of the upper horizontal frame member 3 of the perimeter frame 1 as shown in Figure 5.
  • This downward deflection of retainers 21 and 27 can be obtained as shown by moving the entire perimeter frame 1 upwardly in the direction of arrow 45 against the bottom of the upper jamb 43 of the window frame 29.
  • the lower retainers 23 and 25 (25 not shown in Figures 5-7), with their downwardly extending, hook-shaped end parts 24 and 26, are then pulled outwardly of their respective lower corner assemblies 13 and 15 (if they have not already been so-pulled outwardly).
  • the upper retainers 21 and 27 return to their relaxed positions at a similar distance "b" above the bottom of the upper frame member 3 as the distance "b” that the lower retainers 23 and 25 are below the top of the lower frame member 7.
  • the hooked end parts 22, 24, 26 and 28 of the retainers 21, 23, 25 and 27 thereby engage the rear surfaces of the upper and lower jambs 43 and 44 of the window frame 29 to hold the perimeter frame 1 securely in the window opening 30.
  • Figures 8-13 show details of two of the corner assemblies 11 and 13 of Figures 1-7.
  • the other two corner assemblies 15 and 17 are mirror images of the corner assemblies 11 and 13, respectively.
  • the upper corner assembly 11 has a central portion 50 with parallel front and rear sides 52 and 54.
  • a relatively large opening 56 is provided in the rear side 54 of the central portion 50, through which the relatively vertically more flexible retainer 21 extends and from which its hooked end part 22 extends rearwardly of the central portion.
  • the distance that the retainer 21 and its hook-shaped end part 22 extend rearwardly from the central portion 50 can be varied, and one possible further position is indicated as 21' by dotted lines.
  • the retainer 21 can be moved, relative to the opening 56, in either direction of the double arrow 58 so that the retainer 21 extends away from the rear side 54 of the central portion 50 to greater or lesser extents.
  • Figure 8 also shows the retainer 21 and its hook-shaped end part 22 being deflected downwardly to a position 21'', indicated by dotted lines.
  • Such forced deflection and the resulting resilient relaxation of the retainer 21 is generally in the vertical direction of double arrow 59.
  • This vertical movement of the retainer 21 is accommodated by the opening 56 which is relatively large in the vertical direction and optionally by the relatively more flexible nature of the retainer 21 which is preferably made of spring steel wire.
  • the lower corner assembly 13 also has a central portion 60 and parallel front and rear sides 62 and 64.
  • a relatively small opening 66 is provided in the rear side 64 of the central portion 60, through which the relatively less flexible retainer 23 extends and from which its hook-shaped end part 24 extends rearwardly of the corner assembly 13.
  • the distance that the retainer 23 and its hook-shaped end part 24 of the lower corner assembly 13 extend rearwardly of the central portion 60 can be varied, and one possible further position is indicated as 23' by dotted lines.
  • the retainer 23 can be moved, relative to the opening 66, in either direction of the double arrow 68 so that the retainer 23 extends from the rear side 64 of the central portion 60 to greater or lesser extents.
  • the lower corner assemblies 13 and 15 support the weight of the perimeter frame 1 and its sheet-like panel 19. For this reason, their retainers 23 and 25 preferably are not allowed to be deflected significantly upwardly by the weight of the perimeter frame 1 as shown in Figure 9 .
  • Such limited vertical movement of the retainers 23 and 25 is obtained by providing openings 66 in the rear sides 64 of their central portions 60 that are relatively small vertically and by making the retainers 23 and 25, if necessary, relatively inflexible, preferably of spring steel wire.
  • Figures 8 and 9 also show that the rear sides 54 and 64 of the central portions 50 and 60 of the upper and lower corner assemblies 11 and 13, as well as of the other upper and lower comer assemblies 15 and 17 (not shown), are provided with an additional, unused opening 56A and 66A, respectively.
  • each of the upper and lower retainers 21 and 23, as well as each of the other upper and lower retainers 27 and 25 (not shown), can alternatively be extended from these additional openings 56A and 66A.
  • the corner assemblies 11 and 13 of Figures 8 and 9, as well the corner assemblies 15 and 17 (not shown) can be placed in either right or left hand positions in the perimeter frame 1 of this invention.
  • the right hand corner assemblies 11 and 13 as shown in Figures 1-8 can also be used on the left hand side of the perimeter frame 1 as its comer assemblies 15 and 17, respectively, as shown in Figures 1-8. This allows a substantial reduction in the number of different components which have to be manufactured and stocked for the perimeter frame 1.
  • first and second legs 72 and 74 extending at right angles to each other from the central portion 50 of the corner assembly 11 and parallel to the first and second sides 52 and 54, are inserted in the adjacent open ends of the frame member 3 and 5 in a conventional manner and are thereby hidden from view.
  • first and second legs 72 and 74 (not shown), extending at right angles to each other from the central portion 60 of the corner assembly 13 and parallel to the first and second sides 62 and 64, are inserted in the open ends of the adjacent frame member 5 and 7 in a conventional manner in Figure 9 and are thereby hidden from view.
  • first and second legs 72 and 74 (not shown), extending at right angles to each other from each central portion 50 or 60 of the each of the other corner assemblies 15 and 17, are inserted in the ends of the adjacent frame member 3, 5, 7 and 9 in a conventional manner and are thereby also hidden from view.
  • the corner assemblies 11, 13, 15 and 17 of this invention including their central portions 50 and 60 and their legs 72 and 74 and their attachment to the frame members 3, 5, 7, and 9, are conventional, except for their retainers 21, 23, 25 and 27 and their interior structures, as described below, by which the retainers can be extended or retracted and their hook-shaped end parts 22, 24, 26 and 28 can be held on to an architectural opening.
  • Figures 10-13 show details of the interiors of the central portion 50 and first leg 72 of the corner assembly 11 which are typical of a central portion and a leg of at least the upper corner assemblies 11 and 17 of this invention.
  • the first leg 72 serves, in a conventional manner, to hold the corner assembly 11 and its central portion 50 in sliding engagement with the hollow interior of an adjacent frame members (such as 3).
  • the interior of the central portion 50 and first leg 72 serve also to hold and restrain movement of the portions of the retainer 21 which do not extend rearwardly and outwardly from the central portion 50through its opening 56 or 56A.
  • Figures 10 and 12 show the retainer 21 in its relatively unextended and undeflected position relative to the interiors of the central portion 50 and first leg 72.
  • Figure 11 shows the retainer 21 in its extended position 21'
  • Figure 13 shows the retainer 21 in its deflected position 21'' relative to the interiors of the first leg 72 and the central portion 50.
  • the interior of the first leg 72 contains an elongated cavity 76 which contains an elongated serpentine, preferably horizontally serpentine, second end part 90, of the retainer 21.
  • the cavity 76 and the second end part 90 of the retainer 21 are both elongated in a direction along the length of the leg 72, i.e., parallel to the first and second sides 52 and 54 of the central portion 50.
  • the cavity 76 be open at the rear side of the comer assembly 11, preferably along substantially the entire length of the cavity 76, to allow the elongated second end part 90 of the retainer 21 to be easily inserted therein with its hook-shaped end part 22 extending outwardly of the opening 56 in the central portion 50.
  • the crests 92 and 94 on opposite sides of the serpentine second end part 90 of the retainer 21 resiliently engage the front and rear walls 78 and 79 of the cavity 76 to frictionally restrain movement of the serpentine second end part 90 of the retainer 21 within the cavity 76.
  • the serpentine configuration of the second end part 90 also serves to keep the retainer 21 from twisting in the cavity 76 so that its hook-shaped end part 22 stays in proper orientation for engaging a window frame 29.
  • the cavity 76 in the first leg 72 is connected, through a rearwardly extending channel 57 in the central portion 50 of the corner assembly 11, to the opening 56 at the rear side 54 of the central portion 50.
  • the channel 57 in the central portion 50 is also open at one side of the corner assembly 11 to allow a central part 96 of the retainer 21 to be easily inserted therein.
  • the central part 96 of the retainer 21 extends through the channel 57 and the opening 56 and becomes thereby rearwardly curved.
  • Figures 12 and 13 show one of the upper corner assemblies 11 and in particular show that, in its first leg 72, the end of the cavity 76 remote from the central portion 50 is relatively narrow in the vertical plane, but the cavity 76 gradually widens vertically towards its other end, as it joins the channel 57. Likewise, the channel 57 gradually widens vertically as it goes from its end in communication with the cavity 76 to the opening 56 in the rear side 54 of the central portion 50. This profile of the cavity 76 allows relatively resilient deflection of the retainer 21 outside of the corner assembly 11 (as shown in Figure 8).
  • each cavity 76 and channel 57 are preferably of constant width vertically and do not widen gradually as they go towards the opening 66, which is vertically smaller than the corresponding opening 56 in the upper corner assemblies.
  • Figures 14-16 show another embodiment of a corner assembly 115 of the invention which is similar to the corner assembly 15 of Figures 1 - 13 and for which the same reference numerals or corresponding reference numerals (greater by 100) are used below for describing the same parts or corresponding parts, respectively.
  • the corner assembly 115 has a central portion 160 connected to a pair of perpendicular legs 72 and 74 (hidden from view) inserted in adjacent frame members 107 and 109 of a perimeter frame of this invention.
  • the rear side 164 of the central portion 160 has rectangular openings 166 and 166A, from one of which 166 a retainer 125 extends rearwardly.
  • the retainer 125 is generally rearwardly curved and arc-shaped and includes: a hook-shaped end part 126; an elongate other end part 190 within a cavity 76 (not shown) within the first leg 107; and a central part 196.
  • the retainer 125 also has a rectangular cross-section that is wider than it is thick to give the retainer enhanced torsional stability.
  • the rectangular cross-section of the elongate end part 190 and central part 196 of the retainer 125 conforms closely to the rectangular cross-sections of the opening 166 and 166A and the cavity 76, so that there is a close fit of the retainer in the cavity and openings to keep the retainer from twisting and so that its hook-shaped end part 126 stays in proper orientation for engaging a window frame.
  • the central part 196 of the retainer 125 has saw tooth serrations 197 on its upper surface for engagement with a worm screw member 145 mounted on the rear side 164 of the central portion 160.
  • the openings 166 and 166A prior to use, can be closed by a break-through wall portion which then can be selectively removed depending on the opening 166 and 166A, through which the retainer 125 is to extend. Only the opening 166 and 166A, from which the retainer 125 is to extend, then needs to be removed, and the exterior surface of the corner assembly 115 can thereby retain a generally smooth and closed appearance.
  • Figure 15 also shows schematically the arc-shaped other end part 190 and central part 196 of the retainer 125, which enable the retainer to move through an arc shaped path, so that its movement between position 125' and position 125" corresponds to an angular track ⁇ .

  • the worm screw 145A is provided with a helical thread 198.
  • the worm screw 145 or 145A can be freely rotated in both directions to adjust the retainer 125 inwardly and outwardly of the central portion 160 through engagement of the saw tooth serrations 197.
  • a hook-shaped end part 126 of the retainer 125 extends outwardly of the aperture 166.
  • the retainer 125 can be moved inwardly and outwardly of the aperture 166, whereby its elongated, rearwardly curved, second end part 190 and its rearwardly-curved central part 196 can be moved inwardly and outwardly of the elongate cavity 76 within the first leg 72 and the connecting channel 57 within the central portion 160.

  • a particular advantage of the corner assemblies 11, 13, 15, 17, 115, 211, 213, 215 and 217 of these perimeter frames is that they can be used in prefabricated window systems, in which drilling of holes is not permitted.
  • Another advantage is that the screen-like panel can be left in position while the window is closed.
  • the windows described with respect to Figures 2-7 usually are provided with a hinged pane opening towards the inside of a building, but in certain countries, there is a preference for windows opening to the outside of a building which may result in an inverse arrangement of parts of the corner assemblies of this invention but which should otherwise be considered to be within the scope of the invention.
