Abstract

The invention relates to a method and an apparatus for producing a glazing strip (2). According to the invention the strip is fabricated from such a one-piece blank that incorporates in a single section a sash portion (3), a glazing strip portion (2) and a rip allowance (4) necessary for separating the glazing strip by rip-sawing. According to the invention the blank is worked and finished by, e.g., painting prior to separating the glazing strip. The glazing strip is separated from the blank (1) assembled as, e.g., a window sash. The method according to the invention is suited to industrial production of glazing strips and compatible sashes, and it provides a glazing strip of correct length with ready mitered ends and, when necessary, painted in the same system as the adjoining sash.

Description

Method and blank for manufacturing a glazing bed of a windo construction.
The present invention relates to a method according to the preamble of claim 1 for producing the glazing strip of window structures.
The invention also concerns a blank according to claim 6 suited to the production of such glazing strip.
A window typically comprises sashes connected to a frame and a panes mounted in the sashes. The pane is conven¬ tionally fixed in the sashes by means of a sealing compound such as putty and a glazing strip. The glazing strip conceals the gap between the pane and the sash, and also covers the sealing compound filling said gap.
In prior-art techniques the glazing strip was made of wood, but a plastic extrusion is increasingly preferred.
The prior-art technique has several drawbacks. For instance, both a plastic extrusion and a wood glazing strip has such a disadvantage in terms of industrial production that said strip must always be cut to dimension and mitered separately for each sash and opening, and moreover, the appropriate stock must be selected from strip specially worked for the purpose. Due to these reasons, material loss as well as awkward measuring and fitting work are unavoidable. Moreover, the glazing strip must be shaped, cut to dimension and finished in separate work phases. If sashes of special dimensions are to be produced, four glazing strips exactly matching said sash must always be available on inventory at the glazing phase. A plastic extrusion has the additional drawback of poor color matching with that of the window sash. When aging, the plastic extrusion has a tendency to warp and shrink. It is an object of the present invention to overcome the drawbacks of the prior-art techniques and to provide an entirely novel method for producing a glazing strip for window structures.
The present invention is based on the concept of produc¬ ing the glazing strip from such a one-piece blank of window sash in which the material incorporates both the sash section and an adjoining glazing strip as well as the rip allowance for ripping apart the glazing strip.
More specifically, the method in accordance with the invention is principally characterized by what is stated in the characterizing part of claim 1.
Furthermore, the blank in accordance with the invention is principally characterized by what is stated in the characterizing part of claim 6.
According to a preferred embodiment of the present inven¬ tion, the window sash blank is worked by, e.g., a joiner into such a section that when the glazing strip is separ¬ ated in a rip saw from the sash section at the appro- priate allowance, a glazing strip of exact matching with the sash is obtained. The rip-sawing of the sash members can be performed prior to their assembly, or as well, after the completed assembly of the members as a sash.
A detail worth noting is that the implementation of the method according to the invention provides a ready-to-rip glazing strip in conjunction with the production of the sash itself. Thus, all finishing and working operations become easier to perform.
According to a preferred embodiment of the invention, the allowance removed in conjunction with the ripping opera- tion of the glazing strip is utilized entirely or partly so as to form an overlap seal.
The invention provides significant benefits. So, a preferred embodiment of the invention provides a glazing strip which is cut to dimension correctly, mitered at both ends, and if necessary, painted with the same paint system as the adjoining sash. The method is particularly suited to industrial production of glazing strips and matching sashes.
The present production process is accentuated by the fol¬ lowing benefits: stock consumption is reduced as the glazing strip and the sash are produced and finished together. Also the paint system can be applied in this fashion without additional cost. Cutting to desired dimensions is advantageously combined with the mitering of the member corners, that is, working of corner joints. Working for mounting of hardware (locks and hinges) can be completed in a single run.
Other benefits and characteristics of the invention will become evident from the exemplifying embodiment described below with the help of the appended drawing, which illustrates an application of the invention. Here, Figs, la and lb show the cross section of the window sash blank prior to working (la) and after working (lb) .
The blank according to the invention is advantageously comprised of an elongated stock 1, made of, e.g., wood and worked in a joiner and shaper to a desired cross section. The section is comprised of two sectional portions, namely a glazing strip portion 2 and a window sash portion 3. Fig. la shows between said portions in dashed lines a rip allowance 4, which is necessary for separating the glazing strip portion 2. The rip allowance is substantially parallel with the plane of the glass pane 5 to be mounted in the sash. The ends of the stock 1 are provided with by joint portions necessary for the assembly of the window sash, and if necessary, the stock is treated by a paint system such as, e.g., painting or impregnation.
The glazing strip 2 is separated from the blank by sawing in a rip saw at the rip allowance 4. The sawing takes place as is shown in Fig. la from the opposite side to the insertion of the pane, whereby an overlap seal 2' is formed to the glazing strip. Because the rip-sawing is performed in the plane of the glass pane 5, said overlap seal forms an angle of essentially approx. 90° angle, which is advantageous in terms of weather-tightness of the sash. Next, the glass pane 5 is fitted in the sash 3 and the strip 2 is reinserted to its place, displaced, however, now after ripping by the thickness of the rip allowance 4 closer to the glass pane 5 than before rip- sawing.
The rip-sawing operation can be performed prior to or after the assembly of the blanks. If desired, even the assembly of the sash can be performed first, followed by the insertion of the glass pane, after which the strip is finally separated.
As is evident from the diagram of Fig. la, the blank 1 is worked so as to leave a slot 6 between the portions 2 and 3 for inserting the glass pane. For optimal working of the blank 1 it is crucial that the width of said slot is at least substantially equal to the sum of the width of the glass pane 5 and the rip allowance 4 to attain maximum tightness of the strip 2 after assembly. This is because the rip allowance removed in ripping operation of the strip 2 is utilized entirely or partly so as to form an overlap seal. Shallow grooves can be made at the rip allowance to prevent flaking of paint from the surface when the strip is separated from the painted blank.
The glazing strip 2 produced according to the invention seals the sash 2 at the side of the glass pane 5.
The details of the described embodiment can be varied within the scope of the appended claims. For instance, any cross section of the blank can be employed as long as the slot 6 reserved for the insertion of the glass pane is sufficiently wide. The rip allowance 4 can also be inclined relative to the plane of the glass pane 5.
