Description

Glazing Frame The present disclosure relates to a glazing frame. In particular, the present disclosure relates to a glazing frame fabrication and accessories required for fabricating the 5 glazing frame and hence providing a window frame assembly.

Background

Window frames may be made from a variety of different materials and fabricated in a plurality of ways. Efficiency of manufacture is important in this very competitive market and hence there have been many developments in manufacturing methods and assembly.

It is known to fabricate frame members of a glazing frame from hollow sections and assemble them using connectors, for example as shown in GB2392196A, presented in figure 1. In this arrangement three frame members are connected using a connector 14. When assembled, a region of the connector 14 is left exposed. In figure 1 this is shown as the square with the 14 underlined ("14"). This is problematic because the frame members tend to be provided as a colour specific to a customer's requirements, and hence the connector 14 must also be coloured at least in the region identified as "14" to the same colour and finish as the frame or else the product looks unfinished and unattractive. Additionally, the material of the connector is generally made of a material having lower heat insulatory properties than the frame members. Hence having a region of the connector 14 exposed means that a heat transfer path is provided.

Also the connector 14 comprises a central body with different lugs which are complicated to manufacture and must be provided in the correct orientation in order to assemble the glazing frame correctly.

As shown in figures 2 to 4, which also show examples of related art, window panes 606 may be fitted and sealed in place on a window frame using a bead 600. In the examples shown, which reflect the conventional means for fitting the bead, a bead 600 is slotted into a groove 602 in the window frame 604 (figure 2). The bead 600 is then pulled back away from the window pane 606 to form a gap 608 between the bead 600 and the glass 606. A gasket 610 is then offered up to the gap 608 between the glass 606 and the bead 600 (as shown in figure 3) and then the gasket is pushed in-between the bead and the window (as shown in figure 4). This process is time-consuming, labour-intensive and if not completed properly, may result in a leak and an unattractive finish.

Hence it can be seen that conventional window frame assemblies comprising a glazing frame and beading assemblies, although effective, require skilled assembly, for example to assemble the frame members and connector correctly, or to enter the beading and then the gasket correctly. The may also provide inefficiencies because the connector 14 must be finished and coloured to be the same as the frame members it connects, or because the gasket must be entered with skill and care between the glass and the beading.

Hence innovations which simplify the assembly of a window frame assembly, to either simplify the manufacture of the glazing frame or elements which make up the glazing frame (for example the beading arrangement or connector) or features of each which simplify the design so they may be more simply assembled, are highly desirable.

Hence there may be provided a glazing frame, a bead assembly for a window frame, a window frame assembly and/or a method of assembling a window frame assembly. The glazing frame according to the present disclosure is advantageous as the frame members may be connected via a connector which is invisible once the joint between the frame members has been made. Also the connectors used are unidirectional and may be thus easier to assemble with the frame members. Also the combination of frame members and different connectors and how the connectors are linked together may result in a more robust structure than examples of related art.

Additionally the bead assembly according to the present disclosure, which may be combined with the glazing frame of the present disclosure to create a window frame assembly of the present disclosure, is advantageous as it provides an easier, quicker and more accurate means of mounting, locating and sealing a window pane in a window frame.

Detailed Description

Glazing Frame The present disclosure relates to a glazing frame as set forth in the appended claims, for example as shown in Figure 5. This may form part of a window frame assembly 200 according to the present disclosure. Hence the window frame assembly 200 may comprise a glazing frame 2 according to the present disclosure, a bead assembly 300 according to the present disclosure and may be assembled according to the present disclosure.

Figure 6 shows an exploded view of the window frame assembly 200 shown in figure 5.

As can be seen, it comprises a number of frame members 10, 20, 30 which will be described in more detail. The frame of the window frame assembly may be provided as a unitary frame 90 divided into two sections 16, 26, one of which is for accommodating a window pane 100, and the other therefore accommodating an outwardly opening casement 110 or the like. In an alternative example, both sections may be configured for accommodating a window pane 100, or both may be configured for accommodating a casement 110 or the like.

These are shown in various further views in figures 7 to 12. In figure 7 the casement 110 is shown in an open configuration. Figures 8, 10, 11 show sections C-C, A-A and B-B through the view shown in Figure 9 of the window frame assembly 200.

Figure 12 shows a part exploded view of part of the glazing frame 2, with a circled region Z, an enlarged view of which is shown in figure 13. The glazing frame 2 comprises a 35 first frame member 10 having an end 12 and a side region 14 which extends from the end 12 of the first frame member. The glazing frame 2 also comprises a second frame member 20 having an end 22 and a side region 24 which extends from the end 22 of the second frame member 20. There is also provided a third frame member 30 having an end 32. This arrangement is also shown in different views in figures 14, 15 and 16.

As shown in figure 16, when assembled, the first frame member 10, the second frame member 20 and the third frame member 30 are coupled together such that substantially all of the end 12 of the first frame member 10 directly abuts substantially all of the end 22 of the second frame member 20. Additionally, part of the end 32 of the third frame member 30 directly abuts the side region 14 of the first frame member 10, and the remainder of the end 32 of the third frame member 30 directly abuts the side region 24 of the second frame member 20. Hence an external view of the frame 2 shows that the join comprises only the first member 10, the second member 20 and the third member 30. Hence the assembly defines a glazing frame 2 divided into a first section 16 defined in part by the first member 10, and second section 26 defined in part by the second member 20, where the first section 16 and second section 26 are divided by the third frame member 30. That is to say, the external surface of the frame 2 at the join of the first, second and third members 10, 20, 30 is defined only by the first, second and third members 10, 20, 30. The external surfaces of the first, second and third frame members 10, 20, 30 may be flush with one another in at least one region of the join.

The third frame member 30 may be provided as a mullion or a transom.

As shown in figure 13, the first frame member 10 and second frame member 20 are coupled by a first connector 40 adapted to fit into the ends 12, 22 of the frame members 10, 20. The first frame member 10 and second frame member 20 may be coupled by using first connector 40, or by more than one first connector 40 as shown in figures 6, 14, 15 and 17.

The first and second frame members each define an engagement cavity 18, 28 which is open at the respective frame member end 12, 22. Each engagement cavity 18, 28 in the first and second frame members 10, 20 are configured to received part of the first connector(s) 40. That is to say, the first and second frame members 10, 20 may each be provided as extruded hollow elements to define longitudinally extending engagement cavities 18, 28 of which each are open at the respective end 12, 22 of the frame members 10, 20.

The, or each, first connector 40 has oppositely directed engagement features 42, 44 each adapted to fit into the open engagement cavities 18,28 of the frame members 10, 20 to provide a reverse butt joint between the frame members 10, 20.

Each of the first frame member 10 and second frame member 20 are provided with apertures 17, 27 to accommodate a fixing member (for example, a screw) 70. The first connector 40 is provided with an additional pair of receiving engagement features (for example, a threaded aperture or passage) 72 for receiving the fixing member 70. The engagement features 72, as shown in the figures, may also be provided as a recess/groove provided between the engagement features 42, 44 and the main body 45 of the first connector 40. Hence when the first connector 40 is entered in the engagement cavities 18, 28 of the first and second members 10, 20, a fixing member 70 may be engaged with each of the apertures 17, 27 in the frame members 10, 20 and corresponding engagement features 72 of the connector 40 to inhibit the first connector 40 from sliding/moving relative to the frame members 10, 20 to which it is fixed.

The third frame member also defines an engagement cavity 38 which is open at the end 32 of the third frame member 30. That is to say, the third frame member 30 may be provided as an extruded hollow element which defines a longitudinally extending engagement cavity 38 which is open at the end 32 of the third frame member 30. The third frame member 30 is coupled to the first frame member 10 and second frame member 20 by a second connector assembly 50 comprising a first part 52 which extends through the first connector 40 into a second part 54 which extends into the engagement cavity 38 of the third frame member 30. The second part 54 of the second connector assembly 50 is spaced apart from the first connector 40 by part of the side region 14, 24 of the first frame member 10 and/or second frame member 20. There may be provided only a single second connector assembly 50, or more than one second connector assembly 50 may be provided, for example two second connector assemblies 50 may be provided as shown in figures 14, 15, one for each first connector 40. The second part 54 may comprise a cuboid body with guide features provided to allow it to easily fit within the third frame member 30. The first part 52 may be provided as a screw or other fixative.

Corresponding recesses 19, 29 may be defined in the side regions 14, 24 of each of 35 the first and second frame members 10, 20 such that when the ends 12, 22 of the members 10, 20 abut the recesses 19, 29, they define an aperture 60 configured to accommodate the first part 52 of the second connector 50 so it may extend through the first connector 40. That is to say, recesses 19, 29 define opposing halves of an aperture 60 when the frame members 10, 20 are in abutment.

The third frame member 30 is provided with an aperture 37 to accommodate a fixing screw 80. An aperture 37 and fixing member screw may be provided for each second connector assembly 50. Each second part 54 of each second connector assembly 50 is provided with a receiving engagement feature (for example, a threaded aperture) 82 for receiving the fixing member 80. Hence when the second part 54 of the second connector assembly 50 is entered in the engagement cavities 38 of the third member 30, a fixing member 80 is engaged with the aperture 37 and corresponding receiving engagement feature 82 to inhibit the second part 54 from sliding relative to the third frame member to which it is fixed.

Perhaps as shown best in figure 6, the said first section 16 and second section 26 have relatively reversed frame members 10, 20 so that the frame sections 16, 26 have oppositely facing glazing rebates 13, 23. The third frame member 30 has a glazing rebate 33, 35 on each opposed side 31 of the frame 30 to form part of the glazing rebate 33, 35 in each section 16, 26. Hence there is provided a unitary frame 2 produced having the two sections 16, 26 separated by a third frame member 30 with relatively reversed glazing rebates 13, 23. One of the sections (for example, the second section 26) is for accommodating a window pane 100, the other section (for example the first section 16) is for accommodating the outwardly opening casement 110 or the like.

The third frame member 30 has a side region 34 on each opposed side 31, the side regions 34 which extend from the end 32 of the third frame member 30. The side regions 34 abut the end 12, 22 of the first and second frame members 10, 20 which from their respective glazing rebates 13, 23.

As shown in figure 17, which is a view from the direction shown as arrow B in figure 16, the engagement cavities 18,28 for each of the connectors 40 may be symmetrical about a centre line of the frame members 10, 30.

Figures 26, 27 show an alternative arrangement to that shown in Figures 13 to 17. The 35 example of Figures 26, 27 has many features in common with the example of Figures 13 to 17, and common features are referred to with the same reference numerals. Similar features to that shown in Figures 13 to 17 are prefixed with a "5" (hence, for example, the first connector 40 of the example of Figures 13 to 17 is similar to the first connector 540 of the example of Figures 26, 27).

The features of a first connector 540 and second connector assembly 550 of the example of Figure 26, 27, in particular a second part 554 of the second connector assembly 550 which extends into the engagement cavity 38 of the third frame member 30, differ from the first connector 40 and second connector assembly 50 of the example of Figures 13 to 17.

The second part 554 of the second connector assembly 550 comprises a first element 556 and a second element 558. The first element 556 may be coupled (that is to say, fixed) to the second element 558. In an alternative example the first element 556 may be formed integrally with the second element 558. That is to say, in an alternative example, the first element 556 and the second element 558 may be provided as a single piece.

As shown in Figures 14, 15, 26, 27 the engagement cavity 38 of the third frame member 30 has a cross-sectional shape which defines the internal volume of third frame member 30. That is to say, the internal volume of third frame member 30 may be defined as a function of, at least in part, the cross-sectional shape of the engagement cavity 38. The engagement cavity 38 (i.e. the cross-section of the engagement cavity 38) comprises a first region 38a and a second region 38b. The first region 38a is adjacent the second region 38b. That is to say, the first region 38a is contiguous with the second region 38h. In the example shown the first region 38a and second region 38b are offset from one another along their length. The second region 38b extends from the first region 38a, with an opening (for example a slot) 38c between the first region 38a and the second region 38b. The cross-sectional shape of the engagement cavity 38 may be described as having a "dog-leg" cross-sectional shape. The cross sectional shape (and/or sectional area) of the cavity 38 (that is to say, the cross sectional shape of the frame member 30) is shown by way of example only, and may have an alternative shape which provides the same or similar effect, for example providing a rigid (and/or stiff) frame member configured for being coupled to other members.

In the present example the cross-sectional shape of the first element 556 is shaped to match (that is to say co-operate, be compatible with and/or fit) the cross-sectional shape of the first region 38a, and the second element 558 is shaped to match (that is to say co-operate, be compatible with and/or fit) the cross-sectional shape of the second region 38b. Hence the second part 554 of the second connector assembly 550 is configured to match (that is to say co-operate, be compatible with and/or fit) with the cross sectional shape of the cavity 38.

Akin to the example of Figures 13 to 17, when the second part 554 of the second connector assembly 500 is entered in the engagement cavity 38 of the third member 30, a fixing member 80 (for example a screw) is engaged with the aperture 37 provided in the third frame member, where the fixing member 80 is engaged with the aperture 37 and corresponding receiving engagement feature 582 (e.g. a hole) in the first element 556, to inhibit the second part 554 from sliding relative to the third frame member 30. When assembled, the first element 556 is located entirely within the engagement cavity 38, and only the second element 558 extends out of the engagement cavity 38 to locate into the first and/or second frame members 10, 20 to give extra stability to the third frame member 30. Hence in this example, as with the example of Figure 13 to 17, the second part 554 of the second connector assembly 550 is spaced apart from the first connector 540 by part of the side region 14, 24 of the first frame member 10 and/or second frame member 20. However, it is the second element 558 of the second part 554 which makes contact with the side region 14, 24 of the first frame member 10 and/or second frame member 20 and is spaced apart from the first connector 540 by part of the side region 14, 24 of the first frame member 10 and/or second frame member 20. Hence the first element 556 may be shorter than the second element 558. The first element 556 may be provided along the length of the second element 558 such that at least one of the ends of the first element 556 is spaced apart from the end of the second element 558 which is closest to it.

The second element 558 fulfils the same function, and has the same features, as the second part 54 of the example of Figure 13 to 17, and hence is configured to receive the first part 52 (i.e. screw/bolt) which extends through the first connector 540 into the second element 558 of the second part 540 of the second connector assembly 550.

The combination of the first element 556 and second element 558, configured to fill the cross-sectional shape of the engagement cavity 38 of the third frame member 30 provides extra stability to the member 30 when the frame members are assembled.

In the example of Figures 26, 27, the, or each, first connector 540 has, as in the examples of Figures 13 to 17, oppositely directed engagement features 542, 544, each adapted to fit into the open engagement cavities 18, 28 of the frame members 10, 20 to provide a reverse butt joint between the frame members 10, 20. The first connector 40 of the examples of Figures 13 to 17 comprises a cavity 41 in its main body 45. The cavity 41 extends along the main body 45 of the first connector 40 between the engagement feature 42, 44 ends. In the example of Figures 26, 27, a main body 545 of the first connector 540 likewise comprises a cavity 541, although this is divided along the length of the first connector 540 by at least one wall 543. In the examples shown in Figure 26, 27 there are provided two walls 543 which divide the cavity 541 in the main body 545 of the first connector 540.

An aperture 46 is provided in the body 545 of the first connector 540 through which the first part 52 (screw/bolt) of the second connector assembly 550 extends. Where present, a wall 543 may extend across the cavity 541 between opposing walls of the first connector 540 to one side of the aperture 46. In examples in which two walls 543 are provided, these may be spaced apart to either side of the aperture 46, thereby strengthening the walls of the main body 545. That is to say the walls 543 are stiffening members for stiffening the main body 545 of the first connector 540, and are located to either side of the aperture 46 so that when the first part 552 of the second connector assembly extends through the aperture 46, the first connector 540 maintains its shape and is more able to resist the forces induced on it by the relative motion of the frame members 10, 20, 30.

Each of the first frame member 10 and second frame member 20 are provided with apertures 17, 27 to accommodate a fixing member (for example, a screw) 70. The first connector 540 is provided with an additional pair of receiving engagement features 572 for receiving the fixing member 70. Each of the engagement features 572 may be provided in a recess/groove provided between the engagement features 42, 44 and the main body 545 of the first connector 540. The engagement feature 572 may be a threaded aperture or passage, which receives the fixing member/screw 70. Conversely, the engagement feature 572 may be a plain hole, and the screw 70 may be a self-tapping screw which in operation cuts its own thread in the passage engagement feature 572.

The apertures 17, 27 and the engagement feature aperture/passage 572 may be positioned so that when the frame members 10, 20 are assembled and the first connector 540 is in position in the frame members 10, 20, the apertures 17, 27 and their respective engagement feature aperture/passage 572 are slightly offset from one another such that the act of entering the fixing member (screw) 70 in the apertures 17, 27 and aperture/passage 572 urges the frame members 10, 20 to be drawn together to that the ends of the frame members 10, 20 are urged into contact, thereby closing any gap between the frame members 10, 20.

This may be achieved by configuring the distance between the end 12 and the central axis of the aperture 17, and hence the distance between the end 22 and the central axis of the aperture 27, to be slightly greater than the distance between the central axis of aperture 46 to each of the apertures/passages 572 of the first connector 40, 540.

Put another way, the distance between the recess 19 and aperture 17 of the first frame member 10 may be greater than the distance between the engagement feature 572 of the first connector 540 and the aperture 46. Likewise, the distance between the recess 29 and aperture 27 of the second frame member 20 may be greater than the distance between the engagement feature 572 of the first connector 540 and the aperture 46 provided in the first connector 40, 540.

Bead Assembly Although not the subject of the appended claims, the present disclosure further described a bead assembly, for example as shown in Figures 18, 19. The bead assembly may form part of, or be provided as part of, the window frame assembly of present disclosure.

The bead assembly 300 may have a length L which extends in a longitudinal direction (for example, into and out of the page as shown in figures 18, 19), and therefore extends along the length of the frame/window pane 100 with which it is associated. A bead 302 forms part of the bead assembly 300. The bead 302 may be defined by a first wall 310 which extends in a first direction A as shown in figure 18, 19 at an angle from a junction 312 with a second wall 314 which extends in a second direction C. The direction C is illustrated in figures 18, 19. The angle may be a right angle, or may be an oblique angle.

The ends 316, 318 of the first wall 310 and second wall 314 distal to the junction 312 are spaced apart from one another. The end 316 of the first wall 310 terminates in a gasket mount (or gasket land) 320 for carrying (i.e. mounting and supporting) a gasket 304. The end 318 of the second wall 314 terminates in a leg 322 which comprises a shaped portion 324 which extends from the end 318 to define a seal receiving recess 340 along the length of the bead 302. That is to say, the end 318 of the second wall 314 terminates in a leg 322 which comprises a recess defining portion 324 which extends from the end 318 to define a seal receiving recess 340 along the length of the bead 302. The entrance to the seal receiving recess 340 faces away from the first wall 310. That is to say, the wall material which defines the seal receiving recess 340 is located between the first wall 310 and the entrance to the seal receiving recess.

In the example shown in Figures 18, 19 the shaped portion is provided as an arcuate portion 324 which extends from the end 318 in a curve towards the first wall 310 and then turns away from the first wall 310 to define a curved seal receiving recess 340 along the length of the bead 302.

Hence in the example of Figures 18, 19 the seal receiving recess 340 has a curved cross-section which extends along the length of the bead 302. Specifically the seal receiving recess 340 may have a circular (i.e. part circular) cross-section. That is to say, it is circular except for the opening to the recess.

Alternatively, as shown in Figure 23, the seal receiving recess 340 may have an elliptical or oval (i.e. part elliptical or part oval) cross-section. That is to say, it is elliptical or oval except for the opening to the recess.

Alternatively, as shown in Figures 24, 25, the seal receiving recess 340 may have a polygonal, or part polygonal, cross-section which extends along the length of the bead 302. In Figure 24 this is provided as a square (i.e. part square) cross-section. That is to say, it is polygonal except for the opening to the recess.

In Figure 25 this is provided as a hexagonal (i.e. part hexagonal) cross-section. That is to say, the seal receiving recess 340 may have a cross section provided as four sides of hexagon. That is to say, it is hexagonal except for the opening to the recess.

Hence in Figure 24 the shaped portion 324 has as a polygonal cross-section so that the seal receiving recess 340 has a first face 380 that extends from the end 318 in a direction parallel to the first direction A, and a second face 382 at an angle to the first face, the second face extending in a direction parallel to the second direction C. In the alternative example of Figure 25 the shaped portion 324 has as a polygonal cross-section so that the seal receiving recess 340 has a first face 380 that extends from the end 318 in a direction parallel to the first direction A, and a second face 382 that extends at an angle to the first face 380 away from the first wall 310 and second wall 312, and a third face 384 that extends at an angle to the second face 382 away from the first wall 310 and towards the plane of the second wall 312 which extends in the second direction C. The leg 322 then extends to a first straight portion 326 which extends from the end of the shaped portion 324 in the second direction C away from the first wall 310. That is to say, the first straight portion 326 extends from the end of the shaped portion 324 in a direction at an angle to the direction A of the first wall 310 (for example at right angles to the first wall 310), and aligned or parallel to the second direction C of the second wall 314. The leg 322 further extends in the series to a second straight portion 328 which extends at an angle from the end of the first straight portion 326 away from the second wall 314. That is to say, the second straight portion 328 may extend at an angle to the second direction C from the end of the first straight portion 326.

The second straight portion 328 may terminate in a foot portion 330 which extends in the first direction A, parallel to the first wall 310. There may also be provided a hook feature 332 which extends from the region where the first straight portion 326 meets the second straight portion 328, the hook feature 322 extending in a direction away from the gasket mount 320. Hence the hook feature 322 may extend in a direction opposite to the first direction A. Thus the hook feature 322 may extend in a direction opposite to the direction the foot 330 extends in.

Hence the end 318 of the second wall 314 terminates in a leg 322 which comprises, in series, the shaped (i.e. seal receiving recess defining) portion 324, the first straight portion 326, the second straight portion 328 and foot 330.

The gasket mount/land 320 defines a groove (or channel) 342 for receiving a compatible engagement feature 344 provided on a gasket 304. The groove 342 extends along the length of the gasket mount 320 in the longitudinal direction (that is to say, into/out of the page as shown in figures 18, 19). Hence a gasket 304 may be engaged with the glazing bead 302 by being fitted to, or in part fitted within the groove 342 which is provided as part of the gasket mount 320.

Put another way, the gasket mount 320 may define a groove/channel 342 for receiving a compatible engagement feature 344 provided on the gasket 304. The compatible engagement feature 344 may be provided with a T cross section, as shown in figures 18, 19. The groove 342 is thus provided with a corresponding shaped cavity so that the gasket engagement feature 344 provided on the gasket 304 is located, engaged and seated within the groove 342. That is to say, the channel 342 has a cross section in the shape of a flattened "C", with a central cavity which is wider than the entrance to the channel.

The gasket 304 may further comprise a sealing ridge 372 which extends in a direction away from the engagement feature 344 in the first direction A. As shown in Figures 18, 19 there may be provided a plurality of sealing ridges 372, which extend in the longitudinal direction L of the seal. The or each sealing ridge 372 may be configured to seal on a glass pane 100. The gasket may further comprise a fin member 370 which extends away from the engagement feature 344 in the second direction C. The sealing ridge 372 is configured to, in use, space the fin member 370 away from the glass pane 100 sealed against the sealing ridge 372.

A sealing member (or cord) 400 may be provided along the length of the recess 340, as best shown in figure 20. The sealing member 400 may have a circular cross section (as shown in Figures 18, 19), an elliptical/oval cross-section (as shown in Figure 23), a square cross-section (as shown in Figure 24), a hexagonal cross-section (as shown in Figure 25), or other polygonal cross-section, or other shaped cross section. The sealing member 400 may comprise a rubber or neoprene material. The sealing member 400 may be provided along the length (i.e. longitudinal direction) of the recess 340, and the sealing member 400 and seal receiving recess 340 are configured (i.e. sized) such that the sealing member 400 may at least in part extend out of the seal receiving recess 340 to bear on a frame member surface 212. Splines 350 may extend radially inwardly from the wall which defines the seal receiving recess 340. These may be configured to hold the sealing member 400 in place and to ensure multiple points of contact along the longitudinal length of the sealing member 400 to adequately provide a seal.

The dual-legged configuration of the glazing bead, which is made of a thin sheet material, ensures that the glazing bead assembly 300 is inherently resilient, and flexible.

The gasket 304 may be provided (i.e. located and/or engaged) in the gasket mount 320 to form the bead assembly 300.

The assembled bead assembly 300 (i.e. comprising the bead 302 and gasket 304) is attachable as one unit to a window frame assembly. That is to say, the assembled bead assembly 300 is attachable in one step to a window frame assembly. This is in contrast to, and overcomes the problem of, examples of the related art in which the bead is fitted first to a frame, and then the gasket is provided in a second step (i.e. after the bead has been fitted).

Window Frame Assembly The window frame of the present disclosure may comprise features of the glazing frame

and bead assembly of the present disclosure.

Hence the window frame may comprise a first frame member 10 which defines a glazing rebate 13 and a second frame member 20 which defines a glazing rebate 23. Both the glazing frame 2, and casement 110 may be considered to comprise a first/second frame member 10, 20 which defines a glazing rebate 13, 23.

In figures 18, 19 a pane of glass 100 is shown fixed to a frame member which may be part of the casement 110 or as part of the second section 26 and hence forms of the second frame member 20. Although shown in the figures as the frame members 10 being provided for location of the casement 110, and the frame members 20 being provided for the location of the window pane 100, in alternative examples the first frame members 10 may be provided for the location of a window pane 100 and the second frame members 20 may be provided for the location of the casement 110.

Hence a first frame member 10 may define a glazing rebate 13 limited on a first side 202 of the frame 2 by a wall 204 which extends along the length of the frame 2. This is shown in figures 18, 19. The window frame assembly 2 may further comprise a receiving recess 206 for receiving the bead assembly 300, where the receiving recess 206 extends along the length of the frame 2 (that is to say, in the longitudinal direction of the frame 2) on a second side 205 of the frame 2 opposite to the first side 202. The bead assembly receiving recess 206 extends into the frame member 10 to define an inner frame portion 210 divided from an outer frame portion 212 by the bead receiving recess 206. The bead assembly 300 comprises the glazing bead 302 and gasket 304 as previously described, fixed to the glazing bead 302 which both extend along the length of the frame 2.

The recess 206 has an opening narrower than the width of the recess, with an overhang 360 which the hook feature 322 is configured to locate against so that, when assembled, as shown in Figure 19, the straight portion 328 and foot portion 330 cannot be extracted from the recess 260 unless the hook 322 is forced past the overhang 360. The overhang 360 may be wedge shaped, as shown in figures 18, 19, the overhang 360 tapering towards the second side 205 of the frame member.

Where the bead assembly is configured such that after the bead assembly 300 has been assembled, that is to say the glazing bead 302 and gasket 304 have been assembled together, the bead assembly 300 is configured to be located in the recess 206 such that the gasket 304 faces, and is spaced apart from, the wall 204 along the length of the frame member 10 and the gasket 304 is configured to seal against the glass pane 100 of a predetermined thickness provided between the wall 304 and recess 206. That is to say the bead assembly 300 may be a bead assembly as previously described.

The bead assembly 300, and sealing member 400 and outer frame portion 212 are configured such that the sealing member bears on the outer frame portion 212 along the length of the frame member 10, to therefore provide a seal to prevent the ingress/passage of water and/or air.

Hence as well as apparatus, there is provided a method of assembling a window frame assembly, as previously described, wherein the bead 302 is assembled with a gasket 304 before it is fitted to its respective the frame member (for example any of the frame members 10, 20, 30). Likewise the sealing member 400 is provided in the bead 302 before it is fitted to the frame member.

The glazing bead 302 and frame members 10, 20, 30 may be made from a metal, for example aluminium. The connectors 40, 50 may be made from a metal also, for example aluminium or steel. The gasket 304 and seal 340 may comprise rubber, plastic or neoprene.

Hence there is provided a frame assembly 2 to form a window frame where the joins between the members making up the glazing frame 2 abut so that only the material of the members is visible in an external view of the frame, and the connectors which hold the members 10, 20, 30 together are contained within the frame members 10, 20, 30 and are not exposed for view. This is advantageous as it means that the connector may be made of a different material and may be finished to a different standard, such that a manufacturer need only provide frame members 10, 20, 30 which are finished and coloured to a customer's requirements, whereas the connector may have a different colour and finish, and indeed be made from an entirely different material. Such an arrangement is also advantageous as there are fewer joints provided, which means the glazing frame is more leak-resistant.

Additionally, in examples of the related art, where frames made from PVC are joined often the members are welded together in order that external surfaces of adjacent frame members are flush. With metal frames (e.g. aluminium frames) welding is not practical since the finish of the frame would be compromised and it is a complex process to finish the frame after assembly. The arrangement of the present disclosure obviates the need for welding entirely since it inherently will produce flush external surfaces.

Thus the frame and window assemblies of the present disclosure provide a solution which obviates the need for welding, thus reducing manufacturing time by avoiding the need for welding and finishing processes.

The first connectors 40, 540 are reversible, and hence can be used either way around, and hence the glazing frame comprising these first connectors are easier to assemble than arrangements of the related art.

Rebates of the frames are provided in the second section 26 (which holds a glass pane 100) and the first section 16 (which holds a casement 110) such that, since the rebates are on the external surface, then glass may be fitted from the inside of a building, and also removed from the inside of a building, which makes fitting and maintenance of the window much easier than examples of the related art. Hence even though the casement or window opens outwards, the glass is still removable from the inside of a building.

The retained gasket 304 of the bead assembly 300 allows for the bead assembly 300 to be assembled prior to being offered up to the glazing frame, and since the beading assembly 300 has been configured to click into place on the frame member, with the gasket 304 in place, then the window pane 100 may be located and sealed more quickly with the beading assembly 300 than the arrangements of the related art (for example, as shown in figures 2 to 4) where a seal is provided after a bead has been located on the frame. The arrangement of the present disclosure is considerably easier to fit, and provides for a more consistent finish and seal than examples of the related art.

The provision of the sealing cord member 400 provides a water and air tight seal, obviating the need for the solution of the related art which is to provide a seal using a wet sealant (e.g. a silicone based sealant, or similar, which cures to a flexible rubber- like consistency) after the bead has been fitted. As is well known in the art, the application of wet sealant is problematic in any situation, as it is difficult to provide a line of a sealant which has consistent fill (and hence seal) and which is tidy and hence aesthetically pleasing. Additionally wet seals are vulnerable until cured, and re-application may be required after curing where the sealant may have "shrunk back" as part of the curing process. Further wet sealants are inherently wasteful, as the packaging associated with the sealant must be disposed of after use. All such considerations do not apply to the seal member 400 of the present disclosure, which one fitted is instantly operable as a seal.

Hence there may be provided glazing apparatus which may comprise one or more of a glazing frame for the construction of a window frame assembly of the present disclosure and a bead assembly according to the present disclosure which allows for a method of assembly of a window frame assembly according to the present disclosure.
