Description

(54) IMPROVEMENTS IN OR RELATING TO GLAZING STRIPS (71) We, B.K.L. EXTRUSIONS LIMITED, a British Company of Factory Centre, Kings Norton, Birmingham B30 3HF, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: The present invention relates to glazing strips.

Over recent years windows for the main living rooms of domestic dwellings have tended to be in the form of large undivided areas of glass which are sometimes referred to as "picture windows". However, for aesthetic reasons such windows may not always meet the taste of the individual occupiers.

The invention provides a glazing strip comprising an- elongate member of generally A section having a longitudinally extending face with adhesive means for securing the member to the surface of the sheet- of glazing material, inclined planar side walls, and formations at the base édges'-of said side walls arranged to extend towards the glazing sheet to mask the adhesive.

The glazing strip may have a flattened apex. It is preferably composed' of 'a rigid extruded plastics material.

The invention also provides a window assembly comprising a sheet of glazing material, the frames surrounding and supporting the sheet. and the first set of glazing strips as'described above, which are. secured to the face of one sheet.

Where glazing strips intersect various forms of junction may be provided. In one preferred form the junction is concealed by a cruciform cover. Alternatively a cruciform i,lug with four male appendages, or a cruciform member affording four sockets, may be used. Where two -or more glazing strips meet at an angle to each other one may'be terrninated at an angle parallel to the izi- dined planar side wall of the adjacent'strip the first mentioned strip being abutted against the other strip.

A kit may be provided which comprises a set of glazing strips as described above and junction members of any required form.

The invention will now be described by way of example only, with reference to the accompanying drawings, in which: FIGURE 1 is a cross-section of a glazing strip in accordance with the present invention: and FIGURE 2 is a cross-section of a modified form of glazing strip.

FIGURE 3 is a perspective view of part of the window and frame showing a form of glazing strip: FIGURE 4 is an exploded view of a junction of some glazing strips concealed by a cruciform cover; FIGURE 5 is an exploded view of a junction of some glazing strips using a cruciform plug; FIGURE 6 is an exploded view of a junction of some glazing strips using a cruciform socket.

Referring now to Figure 1 this shows a glazing strip in the form of an elongate member 10 which is intended to be secured to the surface of the glass of the picture window to simulate a structural member which divides the area of the glass into a number of smaller areas. The member 10 is of generally A-section with a flattened snex 12. the base 14 of the section being intended to lie adiacent the surface of the 'hasps. Preferably the member 10 is composed of a rigid plastics material, such as rigid PVC, which may conveniently be manu- factured by an extrusion method.

In order to. secure the member 10 to- the glass, 'the member carries an adhesive strip '(not shown) in the channel defined between the base 14 of the section and the cross member 16 of the section. The adhesive strip is. of similar cross-section to that of the channel and is adhered to the outer surface of the cross-member 16. The outer surface of the adhesive. strip carries a selfadhesive coating and extends slightlv bevond 'the base 14 of the member 10 to engage the glass. This outer adhesive coating is protected by a backing strip which is removed prior to application of the member 10 to the glass.

The adhesive strip may extend along the entire length of the member 10 or may be in the form of individual lengths arranged at intervals along the member.

Advantageously, the adhesive strip may be composed of a compressible material which carries an elastomeric or acrylic adhesive. A suitable adhesive strip may be formed from an adhesive tape such as that sold under the Registered Trade Mark "Silbo tape".

The member 10 shown in Figure 1 is particularly suitable for use on the external surface of the glass. A complementary member 20 for use on the internal surface of the glass is shown in Figure 2. This member is of flatter cross-section than that shown in Figure 1 and the cross member 22 of the section is divided, a respective adhesive strip being secured to each of the two parts of the cross member.

In use, it is envisaged that several such glazing strips would be applied to the glass to extend horizontally and vertically across the window to divide the window into a number of smaller rectangular areas, the strips being cut to the required length by the user. Alternately the strips may be applied to the glass to extend diagonally across the window to divide the window into smaller rectangular or diamond-shaped areas to simulate the appearance of leaded panes.

Figure 3 shows part of a window as semb y, comprising in this particular example a portion of window frame 24 and one corner thereof, and a sheet of glass 26 set in the frame. An arrangement of glazing strips is attached ta the window. A first set comprising elongate members 10 is attached to the exterior of the window, a second set comprising elongate members 20 is attached to the interior of the window. The members 20 are of the same width as the members 10 and when placed in the same position one on each side of the sheet of glass they mask the adhesive which attaches each of them respectively to the glass. A junction 30 is formed by running one glazing strip continuously, in this case it is a vertical one, and abutting the other strips, in this case the horizontal ones, up against the side of the first strip. Careful cutting of the edges to the required angles is needed to make a neat joint.

A preferred form of junction 30 is shown in a exploded view Figure 4. This shows a cruciform cover 32 which is placed over the junction and gives a neat appearance.

This reduces the need for accuracy when cutting the members to make joints.

Two alternative forms of junction are shown in Figures 5 and 6 respectively. Figure 5 shows a cruciform plug 34 with projecting spigots which engage firmly within the interior of the adjacent members. Figure 6 shows a cruciform member 36 with four appendages each affording a socket into which elongate members are slid.

If desired, a kit may be provided comprising a set of glazing strips and a plurality of junction members. The kit may also include a mitre-block to enable the ends of the bars to be accurately cut to an angle if desired. It is to be understood that such a kit of connecting pieces and other parts is not essential and that the strips may be used in an effective manner without the rest of the kit.

WHAT WE CLAIM IS: 1. A glazing strip comprising an elongate member of generally A-section having a longitudinally extending face with adhesive means for securing the member to the surface of a sheet of glazing material, inclined planar side walls, and formations at the base edges of said side walls arranged to extend towards the glazing sheet to mask the adhesive.

2. A glazing strip according to claim 1 further having a flattened apex.

3. A glazing strip according to claim 1 or claim 2 composed of a rigid extruded plastics material.

The adhesive strip may extend along the entire length of the member 10 or may be in the form of individual lengths arranged at intervals along the member. Advantageously, the adhesive strip may be composed of a compressible material which carries an elastomeric or acrylic adhesive. A suitable adhesive strip may be formed from an adhesive tape such as that sold under the Registered Trade Mark "Silbo tape". The member 10 shown in Figure 1 is particularly suitable for use on the external surface of the glass. A complementary member 20 for use on the internal surface of the glass is shown in Figure 2. This member is of flatter cross-section than that shown in Figure 1 and the cross member 22 of the section is divided, a respective adhesive strip being secured to each of the two parts of the cross member. In use, it is envisaged that several such glazing strips would be applied to the glass to extend horizontally and vertically across the window to divide the window into a number of smaller rectangular areas, the strips being cut to the required length by the user. Alternately the strips may be applied to the glass to extend diagonally across the window to divide the window into smaller rectangular or diamond-shaped areas to simulate the appearance of leaded panes. Figure 3 shows part of a window as semb y, comprising in this particular example a portion of window frame 24 and one corner thereof, and a sheet of glass 26 set in the frame. An arrangement of glazing strips is attached ta the window. A first set comprising elongate members 10 is attached to the exterior of the window, a second set comprising elongate members 20 is attached to the interior of the window. The members 20 are of the same width as the members 10 and when placed in the same position one on each side of the sheet of glass they mask the adhesive which attaches each of them respectively to the glass. A junction 30 is formed by running one glazing strip continuously, in this case it is a vertical one, and abutting the other strips, in this case the horizontal ones, up against the side of the first strip. Careful cutting of the edges to the required angles is needed to make a neat joint. A preferred form of junction 30 is shown in a exploded view Figure 4. This shows a cruciform cover 32 which is placed over the junction and gives a neat appearance. This reduces the need for accuracy when cutting the members to make joints. Two alternative forms of junction are shown in Figures 5 and 6 respectively. Figure 5 shows a cruciform plug 34 with projecting spigots which engage firmly within the interior of the adjacent members. Figure 6 shows a cruciform member 36 with four appendages each affording a socket into which elongate members are slid. If desired, a kit may be provided comprising a set of glazing strips and a plurality of junction members. The kit may also include a mitre-block to enable the ends of the bars to be accurately cut to an angle if desired. It is to be understood that such a kit of connecting pieces and other parts is not essential and that the strips may be used in an effective manner without the rest of the kit. WHAT WE CLAIM IS:
