Description

Sliding window

The invention relates to a tubular section for a sliding window, comprising a central cavity and disposed on either side thereof flanges for forming accommodation grooves for a pane. Such a tubular section is known from German Patent Application 1,815,644, which has been laid open for inspection.

The above-mentioned patent application discloses a section which corresponds to the above description and which is intended for carrying two sliding panes, while provision is made at both sides of the. section for a collar which grips over the edge of the window frame on which the section is placed as the sill member.

Such a section is of very specific dimensions which are adapted to the window frame in which such a sliding window must be placed; if the window frame is of a different sire, either a different section has to be chosen, or skill has to be used to ensure proper fitting of the section. The object of the present invention is to produce a section of the above-mentioned type, which does not have the above limitation, and to that end the tubular section according to the invention is characterized in that it is provided on one side with a cover flange and on the other side with section fixing means. A tubular section according to the invent ion, which is provided on only one side with a cover flange which can rest against the outside of the mounting frame in which such a section has to be placed, while on the other side provision is made for fixing means for fixing the section to the above-mentioned mounting frame, can of course be placed in any desired mounting frame, so long as the width thereof is sufficient to contain the width of the section, including the fixing means. The section fixing means of the tubular section according to the invention can be in many different forms and act in many different ways; in its simplest form a section fixing means can be made up of a fixing flange running over the length of the section and being coplanar with the supporting face of the section. Such a flange is expediently provided with bores for fixing - for example screwing - the section to the mounting frame in which the section has to be placed, for example a wooden mounting frame. In particular, however, the section fixing flange has a cavity for accommodating a section reinforcing means. In an attractive embodiment of the tubular section according to the invention, said tubular section is made of a plastic, for example polyvinyl chloride. In view of its shape, such a plastic section is of low innate rigidity, which in the case of larger dimensions is insufficient for fitting the plastic section frame in a wooden mounting window frame, so that an additional reinforcement is needed in the section. For that purpose the section can have a cavity to take such a reinforcing means, said cavity being in particular in the part of the section also containing the fixing means for the section.

Such a cavity is advantageously L-shaped for taking a section reinforcing means of such L shape. Such a section reinforcing means can be, for example, an angle steel.

A very common use for a tubular section of the type discussed here is for placing a double sliding window. In such a case two plastic frames made of such sections are placed parallel to each other in a mounting frame or window frame, each of the plastic frames comprising a sliding window in two parts. Two parallel sliding windows are then used if good heat and sound insulation are desired from the window unit. The tubular section according to the invention is excellently suited to such an application; in order to increase the sound insulation, it is advantageous to make a large space between the two sets of frames, and the space between two sections is filled up with a sound-absorbing material. In order to permit good confinement of such material, it is very advantageous for the tubular section according to the invention to be provided at the side having the section fixing means with a cavity so that, in conjunction with an identical tubular section positioned in mirror-image fashion in the same mounting frame, it takes the long side of a cover plate which covers the said space between the tubular sections. A sound-absorbing material can now be placed in the space between the parallel tubular sections; placing a cover plate means that said absorption material is confined well and is out of sight.

The invention also relates to a welded plastic frame for placing a sliding window assembly in a mounting frame, said plastic frame according to the invention being characterized in that it is made up of four tubular sections according to the invent ion which are mitred to each other in the corner points.

A frame in which a sliding window unit has to be placed comprises in general two uprights and a lintel and sill member. In order to place two sliding windows in such a frame, a tubular section must be fix-ed to each of the parts of the mounting frame for each of the sliding windows. Said tubular sections are sections according to the invention as described above; the tubular sections for each of the parts of the mounting frame are identical and can be mitred to each other in the corner points, for example by welding.

For a further improvement of the sound insulation, a section according to the invention is used in which the section has a cavity for taking the long side for a cover plate. A sound-absorbing material can be placed between two sections fixed parallel to each other, while said sound absorption is confined by placing of the cover plate.

In order to improve the sliding action of the windows to be placed., in the window accommodation grooves of the sections, slide rails are provided in the tubular sections disposed on the sill member of the mounting frame.

The height of the slide rails is greater than half the depth of the groove, so that the section can be the same all the way round and the panes are easy to fit. In particular, a welded plastic frame of the type described above mates in detachable fashion with another identical plastic frame, the said other plastic frame being disposed in mirror-image fashion.

When two such plastic frames have been placed in a mounting frame, the connection between the plastic frames is detached and removed in order to prevent sound transfer from one frame to the other.

The invention will now be explained with reference to the drawing, in which

Fig. 1 represents a cross section of a positioned double sliding window, using tubular section according to the invention;

Fig. 2 is a cross section of the same arrangement as in Fig. 1, but with the space between the two tubular section being increased, Fig. 1 shows a tubular section 1 which is formed by a central central cavity 2 with an upward-facing protuberance. On either side of said protuberance are flanges 3 and 4, whose top side in the embodiment shown here lies essentially coplanar with the top side of the protuberance which is present on the cavity 2.

Accommodation grooves which can accommodate, for example, glass panes 5 and 6 are formed in this way between the protuberance on the central cavity 2 and the flanges 3 and 4. In the embodiment shown here the panes 5 and 6 simply rest in the accommodation grooves; of course, the edges of such panes can also be surrounded by end fillets which are known per se. One type of end fillet is in that case suitable for being accommodated by the accommodation grooves in the tubular section; end fillets of a different type are fixed as counterparts on two different windows and can slot into each other; such end fillets are described, for example, in Dutch Patent Application 83.03719, filed by applicants. The above-described section 1 also has on both the protuberance of the central cavity and on the flanges 3 and 4 spaces for accommodating, for example, brushes or in general sealing means for obtaining the best possible draught exclusion. Such brushes or sealing means are, however, generally used and will not be discussed further here. As can be seen in Fig. 1, the section 1 has on one side thereof a collar 7 which projects over the mounting frame 15 and connects to said mounting frame part when a sealing means 17 is used. On the opposite long side of the section 1 is a cavity 8 in which a tubular section reinforcing means 9 in the form of an angle steel is provided. The section can be fixed to the part 15 of the mounting frame by means of screw 18, several of which can be placed in the

Lengthwise direction of the tubular section. At the side of the section where the tubular section fixing means are located one can also see a cavity 10 for accommodation of a cover plate 11; such a cover plate can be accomimodated through the cooperating of two positioned sections 1 and 1'; the plate 11 completely covers the space between the sections 1 and 1'. As will be indicated later, such a space can be filled with sound-absorbing material.

The accommodation grooves 12 and 12' in the section have slide rails 13 and 13' if the section is present on the sill member, as in this figure.

Fig. 1 shows schematically by reference number 16 that any condensation or rainwater running off the windows 5' and 6' can be drained away through openings located in the accommodation grooves or in the part walls of the cotlar 3'. The openings can be provided in the accommodation grooves simply by .milling from the top.

The opectings which are needed in the collar can be formed by local milling of the bottom side of the collar, milling taking place in particular at the partition between the collar 3' and the central cavity 2'.

Fig. 2 outlines essentially the same situation as Fig. 1 as regards the sections; the tubular sections are, however, in this case placed much further apart.

The plate 21 serves to cover a sound-absorbing material 24 provided between the tubular sections. Reference number 23 indicates schematically a cover plate which is comparable to the plate 21, and which is present between the tubular sections which are fixed to the uprights of the mounting frame in which the sliding windows shown are placed.
