Definitions

  • the present invention relates to a perimeter frame and flexible sheet assembly forming a substantially flat polygonal framed panel, preferably a framed insect screen. It also relates to a corner assembly for joining elongate legs of the or a frame which can be mounted adjacent an architectural opening.
  • the comer assembly may find particular use in the frame of an insect screen to be mounted over a window or door opening.
  • Assemblies which include a plurality of elongate frame members, each having a generally rectangular tubular cross-section and an outwardly open longitudinal spline groove on an exterior side thereof; a plurality of nodal connectors or corner assemblies, each engaging a longitudinal end of at least two adjacent ones of said plurality of elongate frame members to form a polygonal perimeter frame, with the longitudinal spline grooves positioned inwardly of the perimeter of said frame, a flexible sheet having a perimeter engaged in said spline grooves and at least one elongate flexible spline fitted in said spline grooves for retaining said flexible sheet.
  • Such an assembly is described in patent document US 2 897 889, entitled: "Screen spline with direct frictional engagement means".
  • Corner assemblies of frames that can be used to removably mount framed insect screens and other sheet-panels on windows and doors are known for example from US 5,431,211 and GB-A-2,236,134.
  • US 5,431,211 describes an insect screen that has a frame with a corner assembly having a retaining protrusion which is slidably held within the comer assembly and can be slid outwardly of a longitudinal side of the corner assembly and into a suitable recess provided in the window frame to hold the screen on the window.
  • EP-A-0,942,141 discloses another corner assembly in which an arm with a flange at its end protrudes from a corner assembly.
  • the flange may be secured over the lip of part of the window opening so as to secure the frame in place.
  • the flexible sheet is retained within the spline groove by a round spline strip. Since the spline strip has to be pressed home into the spline groove together with an edge portion of the flexible sheet this operation requires some kind of implement with which pressure can be applied locally on a small area at the time. While working around the circumference of the perimeter frame with such an implement, great care is needed in centering the implement on the spline strip, so as not to damage or mar any of the sheet material directly surrounding the spline groove. With a round spline strip this has not always been an easy task.
  • the known assemblies have also been hampered by a sometimes indeterminate fit of the round splines strip in a generally rectangular spline groove. Nevertheless the known assemblies have generally performed satisfactorily as long as the spline groove in respect to the direction of spline strip insertion has been kept perpendicular to the plane of the flexible sheet. A less favourable appearance on one side of the panel has thereby been accepted in compromise.
  • corner assemblies with hinges, pivots and the like.
  • the requirements for these hinges and pivots vary according to the particular installation.
  • corner assemblies provided with such hinges or pivots are unsuitable for use in installations where a suitable recess or lip is provided for attaching the frame as mentioned above.
  • the present invention provides a perimeter frame and flexible sheet assembly forming a substantially flat polygonal framed panel, said assembly including a plurality of elongate frame members, each having a generally rectangular tubular cross-section and an outwardly open longitudinal spline groove on an exterior side thereof; a plurality of nodal connectors, each engaging a longitudinal end of at least two adjacent ones of said plurality of elongate frame members to form a polygonal perimeter frame, with the longitudinal spline grooves positioned inwardly of the perimeter of said frame, a flexible sheet having a perimeter engaged in said spline grooves and at least one elongate flexible spline fitted in said spline grooves for retaining said flexible sheet, wherein said flexible spline is substantially U-shaped in cross-section, having yieldable sides and a detend edge, wherein said spline groove is inwardly contoured to offer an undercut edge and wherein said detent edge engages behind said undercut edge for retaining said flexible sheet.
  • a method of constructing a frame for mounting adjacent an architectural opening comprising:
  • a corner assembly for joining elongate legs of a frame for mounting adjacent an architectural opening, the corner assembly including:
  • a single type of corner assembly may be used for joining elongate legs to form a frame and, by varying the type of insert, the frame may be mounted in a variety of different ways.
  • guide surfaces are provided which are aligned with respective end portions such that the insert can be guided so as to be movable by operation through the aperture to and from one of the end portions or can be guided so as to be movable by operation through the aperture to and from the other of the end portions.
  • the comer assembly can be provided with an insert which is movable in a predefined direction so as to secure or detach the frame from the architectural opening.
  • the internal cavity includes first and second pairs of parallel walls forming the guide surfaces.
  • the corner assembly further includes wells extending from the internal cavity towards the end portions and suitable for housing compression springs for biassing the insert away from the end portions.
  • the insert and any features associated with it for securing the comer assembly to the architectural opening can be biassed towards one particular position.
  • This arrangement can be used to ensure that the corner assembly remains in its secured position unless a user intervenes to overcome the bias of the compression spring.
  • the corner assembly further includes passageways extending parallel to the respective guide surfaces from the internal cavity to and through respective edge surfaces of the comer assembly such that the insert can be provided with a protrusion extending into one of the passageways and, by operation through the aperture, selectively out of the respective edge surface.
  • the protrusion extending out of the edge surface may be used to secure the corner assembly in place.
  • the protrusion By operating the insert through the aperture so as to move it against the bias of the compression spring, the protrusion can be withdrawn into its passageway so as to release the corner assembly.
  • the corner assembly further includes an undercut channel running along at least one edge surface such that additional components can be attached to the corner section by sliding into the channel.
  • a range of different components may be provided with an appropriate profile to slide into the undercut channel and be secured there.
  • the biassed insert and protrusion can be used to prevent the additional component from sliding out of the channel.
  • the corner assembly can be provided with an insert which has a magnetic portion extending through the aperture generally flush with the respective surface of the corner assembly.
  • This type of insert allows a frame to be mounted adjacent the architectural opening by means of magnetic attraction.
  • An insert can be provided for fitting into the cavity together with a compression spring for insertion into one of the wells so as to bias the insert away from the respective end portion.
  • An arm with a flange can then be provided for attachment to the insert so as to extend through the aperture, the flange being for mounting to the lip of a previously installed frame of the architectural opening.
  • the flange and arm can be used to secure the comer assembly in place, but can be moved against the bias of the compression spring so as to move the flange clear of the lip and allow mounting and demounting of the corner assembly.
  • the insert includes a detachable stop, the insert being prevented from movement in the cavity when the stop is still attached and being movable against the bias of the compression spring when the stop has been detached.
  • the arm is adjustably mounted to the insert so that the distance between the flange and the corner assembly can be varied.
  • the mounting flange can be adapted to different installations.
  • An insert can be provided which has a control key positioned in the aperture and a protrusion extending laterally for insertion into one of the passageways and selectively out of the respective edge surface, together with a compression spring for insertion into one of the wells so as to bias the insert with the protrusion extending out of the respective edge surface.
  • the insert can be used to secure additional components in place.
  • a mounting component can be provided for sliding into the undercut channel of the corner assembly and for mounting the corner assembly, the mounting component having a recess for receiving the protrusion through the respective edge surface such that the mounting component is prevented from sliding within the undercut channel and is held in place.
  • Suitable mounting components include a pivot pin to extend out of the undercut channel and pivot in a bearing surface of a mounting bracket, a hinge and a support slider having a rotatable support surface for fitting into a guide track for slidably mounting the frame.

  • elongate legs 8 and corner assemblies 10 may be assembled together to provide frames of any desired size and with a very neat appearance at the corners.
  • Figure 3 illustrates the corner assembly of Figure 1 separated into its two component parts, namely a top half 10a and a bottom half 10b.
  • walls define a cavity 12 in which an insert may be placed.
  • an aperture 14 is provided in the bottom half 10b so as to provide access to the cavity 12.

  • an additional corresponding aperture may be formed in the top half 10a.
  • an insert 50 may be provided to fit into the cavity 12.
  • the cavity is formed from a first pair of parallel walls 16a,16b and a second pair of parallel walls 18a and 18b.
  • the insert 50 includes a plate-like member 52 which fills the space between the parallel walls 16a,16b and 18a,18b such that the insert 50 is held securely in place and cannot move laterally.
  • the insert 50 also includes a magnetic portion 54 which extends at least into the aperture 14 of the corner assembly 10, preferably completely filling the aperture 14. Furthermore, the outer surface of the magnetic portion 54 preferably lies flush with the outer surface of the corner assembly 10.
  • a frame may be provided with magnets at each of its corners such that it can be secured to a window or door frame by magnetic attraction.
  • the magnetic portion 54 can extend either side of the plate-like member 52. This can be used to provide additional stability to the insert 50 or additional space for magnetic material. Alternatively, of course, where both halves 10a,10b of the corner assembly 10 are provided with apertures 14, the corner assembly can be provided with a magnetic portion flush with both the front and back surfaces.
  • FIG. 7 A second arrangement is illustrated in Figures 7 and 8.
  • an insert 70 is provided for receiving through the aperture 14 an arm 72 having a flange 74 at its end.
  • the insert 70 is provided with a plate-like member 76 similar to the plate-like member 52 of the insert described with reference to Figure 4.
  • the plate-like member 76 does not completely fill the space between the parallel walls 16a,16b and 18a,18b.
  • a detachable stop 78 is provided on the edge of the plate-like member 76. This abuts with the walls of the cavity so as to prevent movement of the insert 70.
  • the plate-like member 76 fills the cavity 12 in such a way that the insert 70 may slide towards or away from one of the ends 2 and 4.
  • the insert 70 can slide to and from the end 4 guided by the walls 18a and 18b.
  • alternative means can be provided to guide the insert such as dedicated protrusions and grooves.
  • the corner assembly 10 is also provided with wells 20 which extend from the cavity 12 towards the ends 2 and 4. These wells 20 are provided to accommodate compression springs such as spring 80 illustrated in the figures.
  • a compression spring may be located in a well 20 and act between an end wall of the well 20 and the insert 70 so as to bias the insert 70 away from the respective end 2,4 of the corner assembly 10.
  • the spring 80 biases the insert 70 away from the end 4, but allows the insert 70 to slide towards the end 4 against the resistance of the spring 80.
  • a guide extension 82 is provided to fit into the well 20 within the spring 80.
  • a frame may be provided as illustrated in Figure 9 with flanges extending from the corners at the top and bottom.
  • Each flange 74 may fit over a lip in the architectural opening, for instance a previously installed window frame of the architectural opening. In this way, the frame of Figure 9 can be secured over the architectural opening.
  • the insert 70 By leaving the stop 78 attached to the insert 70 for the corner assemblies 10 at the bottom of the frame, the insert 70 is prevented from moving such that the corresponding arms 72 and flanges 74 are held rigidly in place with respect to the frame. In contrast, by removing the stop 78 of the inserts 70 in the top corner assemblies 10, the inserts 70 are able to be moved against the resistance of their compression springs away from the edges of the corner assembly 10. In particular, with the flanges 74 aligned with the direction of movement, they can slide to and away from the lip over which they are to extend.
  • the arm 72 may be adjustably mounted to the insert 70.
  • a side of the arm 72 is formed with teeth 84 by means of indentations or perforations. Only the back of the teeth 84 are visible in Figure 8.

  • the arm 72 is inserted into the slot 90 adjacent the helical body 86.
  • By rotating the helical body 86 it is possible to adjust the amount by which the arm 72 extends from the insert 70.
  • FIGS. 10 and 11 illustrate a further arrangement which may be used in a number of different ways to be described below.
  • An insert 100 is provided with a plate-like member 102 and detachable stop 104 similar to the plate-like member 76 and stop 78 described above.
  • the insert 100 can be secured in place by retaining the stop 104 or can be allowed to slide within the cavity 12 by removing the stop 104.
  • the insert 100 is intended to slide to and from the first end 2 guided by the walls 16a,16b. Also, like the insert 70, the insert 100 is provided with a compression spring 106 to be fitted in a well 20 so as to bias the insert 100 away from the first end 2. An extension 108 is also provided to help guide the spring 106.
  • the corner assembly 10 is also provided with passageways 22 which extend from the cavity 12 out through the edges of the comer assembly 10.
  • the insert 100 is provided with a protrusion 110 which extends generally parallel to the direction of movement of the insert 100 and into a passage 22.
  • the insert 100 is also provided with a button or key 112 which extends into the aperture 14. By means of this key 112, it is possible for the user to slide the insert 100 against the bias of the compression spring 106 towards the respective end of the corner assembly 10. As a result of this, the protrusion 110 is moved within the passageway 22.
  • the protrusion 110 is arranged to have a length such that it normally protrudes into a channel 28 formed in the edge of the corner assembly 10, but, can be withdrawn from the channel 28 into the passage 22 by moving the insert 100 with the key 112 against the bias of the spring 106.

  • the secondary protrusion 111 can slide along its corresponding slotted opening as the protrusion 110 moves axially in its passageway.
  • the protrusion 110 is unable to slide (perpendicular to its axis) in its corresponding slotted opening.
  • This mechanism can be used to lock various additional components to the corner assembly 10. Some of these are described below.
  • the corner assembly 10 is provided with undercut channels 28 along its edges. As illustrated in Figure 3, walls 24 are provided along the edges of each half 10a,10b of the corner assembly 10 so as to form the undercut space 28.
  • Additional components having an appropriate profile may thus slide into the undercut channels 28 from their ends at the corner 26 of the corner assembly 10.

  • the insert 100 may be moved against the bias of the spring 106 so as to withdraw the protrusion 110.
  • the pivot pin assembly 120 may then be slid within the channel 28. With the pivot pin in position as illustrated in Figure 12(b), the protrusion of the internal insert 100 is allowed to engage a recess (not shown) of the pivot pin assembly 120 so as to secure it in place.
  • the corner assembly may then be positioned as illustrated in Figure 12(b) so as to engage the pivot pin in the bearing 126 of the bearing block 120.
  • the pivot pin assembly 120 of the corner assembly 10 may first be slid fully within the channel 28 such that the frame may be positioned immediately adjacent the bearing block 122.

As illustrated in Figures 14(a) and (b), the additional profiled sections are dimensioned so as to fill the channel 28 formed in the corner assembly 10. Thus, the profiled sections of the hinge component can be slid through the corner 26 and along the channel 28 of the corner assembly so as to secure the hinge component to the corner assembly.
  • the hinge component can be provided with an aperture to receive the protrusion 110 such that it is then held in place similar to as described with reference to Figures 12(a) to (c).

  • Apertures 132 are provided such that fasteners, such as screws or rivets, may be provided through the profiled section 130 into the channel 9 so as to secure the profiled section 130 from sliding along the channel 9.
  • Figure 15 illustrates another form of hinge component. As illustrated, it is provided only with the profiled section 130. However, it could be provided with the additional profiled sections 131.
  • the hinge components of Figures 14 and 15 differ in that, with the hinge component of Figure 14, the two halves of the hinge are not secured to one another. Hence, by sliding one half relative to the other along the pivot axis, the two halves may be separated. This may be useful when the hinge component is used with its pivots oriented vertically since the frame can be lifted off the architectural opening to which it is mounted. In contrast, the two halves of the hinge component of Figure 15 are not separable.
  • Figure 16 illustrates an arrangement similar to that of Figures 12(a) and (b) or 13 wherein the bearing block 122 or 128 is replaced by a bearing block 142.

  • the spline groove 305 is in an oblique position with respect to a plane through the sheet 311 of the assembly. This centers the sheet material or insect screen mesh 311 with respect to the front and rear walls 323,325 of the frame member 301. This is aesthetically more attractive, but also reduces the angular deflection at which the sheet 311 extends from the groove 305. This is of particular importance with insect screen material, which frequently consists of glass fiber filaments coated with Polyvinylchloride resin.
  • the spline 313 basically derives its flexibility from its U-shaped cross-section and thus can be made from a relatively rigid material, so that it retains its shape sufficiently well for the detent edge 319 to stay engaged behind the undercut edge 321 once positioned with the sheet material 311 sandwiched therebetween. As shown the spline 313 is positioned in the groove 305 with its hollow interior exposed to the exterior.
  • Figure 21 is an isometric representation of a length of frame member 301, 303 as used in the present invention.
  • the frame member 301, 303 is preferably obtained from sheet metal through roll forming.
  • the undercut edge 321 can be conveniently obtained by one of the metal sheet margins folding back over the opposite metal sheet margin.
  • the frame member could be provided with an undercut groove 327 on a side which ends up outwardly of the assembled frame.
  • Such a groove 327 in particular when it also continues over the nodal elements 307, is useful in the mounting of additional accessories, such as flexible sealing elements (brushes or the like) or hinge elements for insect screen doors etc.
