Description

Technical field

The present invention relates to a device to fasten a removable cross piece, a so called glazing bar, against a door or window frame or similar frame piece, and where the device is a clip which is designed to cooperate with the standard solutions that exists by the glazing bars for the attachment between the clip and the glazing bar.
The invention is firstly intended to be used in combination with a window and its window frame. Naturally the invention can also be mounted in other types of frame pieces such as doors or other window like frame pieces, where removable glazing bars are desired.

Background of the invention

Glazing bars is of aesthetical reasons mounted against, as an example, window surfaces in windows or doors, and in that case as external constructions fastened in one or another way in for example the frame pieces of the window. It must be easy to remove the glazing bars for service, for instance window-cleaning, and thereafter it must be easy to put them back again.
Earlier solutions for fastening of glazing bars against the frame pieces of the window is principally based on that the frame pieces is provided of wood or other materials, in which it is rather easy to fasten different kinds of fastening devices. A so called clip is frequently used which is fastened against the frame piece, either at the manufacturing in the plant or by mounting afterwards at the building site or at home at the individual house-owner. At the mounting of the complete glazing bars the glazing bars is usually first of all fitted into the frame piece, and when this is done the position of the clips can be determined, whereupon the glazing bars is removed and the clips is fastened in the frame piece with some kind of fastening element, usually with nails or screws. When the clip, which usually includes a sort of male element, is in place the glazing bars is mounted again, usually by snapping in against those in the frame piece mounted clips while in the ends of the glazing bars a cooperating detail is provided of the type female element that permit this type of mounting.
Nowadays it is more and more common with aluminum cased windows, where the frame piece includes a framework of wood or other material, which is cased with an aluminum profile, further on named frame profile, to achieve a better weather resistance and to reduce the service over the lifetime of the window.
When fastening of the clip is desired, for instance with nails, screws or similar fastening elements, firstly a hole must be made in the frame profile. This is depending on the hardness of the aluminum and the nature of the surface difficult to carry out at the building site in a safe manner and without to damage surrounding aluminum surfaces that easily are scratched. The making of the hole therefore had to be made already by the factoring of the windows at the factory. This results in the disadvantages that it is difficult to stock windows because all different combinations and design of glazing bars exists and it is difficult to foresee manufacturing volumes of all different variants. Additionally, with the present solutions, it is difficult to perform a montage afterwards outside the factory.

Summary of the invention

With the present invention the object to solve those problems is achieved by that at first the need of making holes in the frame profile is eliminated. With the first aspect of the invention the object is achieved that by that the clip of the initially specified art is designed to be pressed in place between the frame profile and a weather strip that is provided between the frame profile and the window surface. The clip has a base surface with a width along the frame profile/weather strip and taken together with the engagement of the clip between the frame profile and the weather strip together with that the clip has a tie-back at its one side, which grips around a part of the corner of the frame profile, the corner that contacts the weather strip, makes the friction between clip, frame profile and weather strip sufficient to retain the clip on the frame profile by removing the glazing bars from the clip. Therefore the need of making holes in the frame profile is eliminated and there is no longer a need to stock windows with pre-assembled glazing bars. This in turn makes both the manufacturing rate and the time of delivery faster while the manufacturing can be concentrated to standard windows in stock. Also the mounting at the building site is faster, since the moment of making holes are eliminated. With the present invention the object to solve those problems are achieved by eliminating the need of making holes in the frame profile.
A preferred form of execution of the invention is that the dimensions of the clip, e.g. the length and the width of said base surface with its tie-back, is tested out to retain the glazing bars in a way that is described above, but are adapted so that the friction and the retaining force isn't too high. The extension of the tie-back is preferably short in relation to the length of the base surface so that the engagement between the weather strip and the corner of the frame profile isn't too strong. The design of the length and width of the clip and the design of the tie-back must with preferred safe margin handle the function, but the clip must still be movable along the frame profile/weather strip. By the assembling this the advantage is that the clip can be pressed in place, approximately in its right position, so that it later can be displaced to its exact position, the position that is given by the fitting in of the glazing bars.
According to a preferred form of execution the base surface of the clip is provided with a center marking at the opposite side relative the tie-back, where the center marking preferable is designed as tip, a v-shaped groove or corresponding. By this form of execution the determination of the position of the clip along the frame profile is facilitated, while in this case for example a center position on the frame profile can be marked in advance, whereupon the clip id fastened by pressing and is positioned with the tip in position for the marking on the frame profile.
According to a further preferred form of execution the base surface of the clip is provided with a heightening, a wart, preferable provided to act as a male element which cooperates with the corresponding female elements at the glazing bars. The wart can in itself be free from the function as male element.
Depending on the demands of the final user/house-owner concerning the safety against falling parts of the glazing bar the invention offer alternative possibilities to anchorage the clip. This since the demand on, for example an individual one-storey house, is totally different to for example a building of several storeys and where a lot of people are moving around the building. According to a further preferred form of execution the clip is provided with an alternative to a further securing of the attachment of the clip against the frame profile or the frame piece by that the wart of the clip is provided with a through hole in the center of the wart and which preferable also passes through the base surface. This hole is preferable used both as guide and as drill guide by a drill operation, to make a hole through the frame profile whereby it is made possible to anchorage the clip in the frame profile or the frame piece with a nail, screw, pop rivet or similar fastening element. By the height of the wart the hole is getting a guiding function so that the drill drills in intended angle through the profile, and additionally also that the fastening element is guided in right angle for fastening in the frame profile/ frame piece. Of course the hole don't has to be a through hole through the base surface, while this base surface preferable is thin, and therefore easy to penetrate by for instance a drill, by an drill operation or direct by a nail, screw or similar at the anchorage of the clip. By that the clip is provide with this function as drill guide a protection is at the same time achieved for the surrounding surfaces of the frame profile that will not be damaged by the hole making, which easily can occur by a drill operation made free by hand. To provide the clip with this form of execution therefore has the advantages in relation to the earlier known solutions that a further securing of the clip is made possible, guiding during the drill operation and a protection of surrounding surfaces of the frame profile by the drilling.
According to a further preferred form of execution said hole is provided with a tested angle in relation to the base surface of the clip, partly for the engagement of the fastening element in the frame profile or the frame piece at desired position and additionally for the performance of the drilling without a conflict between usually used drill machines and the window surface during drill operation.
According to a further preferred form of execution the wart of the clip includes a chamfer at the side closest to the first side, accordingly closest to the window surface. In this way the clip is no obstacle when the window is cleaned with conventional window cleaning utensils as for example window scrapers and the like.
According to a further preferred form of execution the clip is provided with an alternative to a further securing of the fastening of the clip against the frame profile by that the clip is provided with an adhesive, e.g. a double-stick tape. This is made possible when the base surface of the clip, its length and width is sufficient large to include the adhesives on the underside of the base surface so that a sufficient anchorage is obtained. Accordingly it is obtained that both an extra securing in addition to the first preferred form of execution and that the surface of the frame profile don't need to be perforated with a hole, which is an advantage if an totally dismounting of the glazing bars and the clips are desired.
From the second aspect the object it is obtained by that a method of the kind that is initially mentioned includes the moment to press the clip in place between the frame profile and a weather strip which is provided between the frame profile and the window surface. When the clip has a base surface with a width along the frame profile/ weather strip and when the engagement of the clip between the frame profile and the weather strip together with that the clip has a tie-back at its one side, that grips around a part of the corner of the frame profile, it is obtained that the friction between the clip and the frame profile/weather strip is sufficient to retain the clip in its position along the frame profile/weather strip when the own weight of the glazing bars loads the clip. In addition the grip is sufficient to retain the clip on the frame profile by the removing of the glazing bars from the clip. Accordingly the need of making holes in the frame profile is eliminated and there is no longer any need to stock windows with pre-assembled glazing bars. That in turn makes both the manufacturing rate and the time of delivery faster since the manufacturing can be concentrated to standard windows kept in stock. Also the assembling at the building site is made faster since the moment with making holes is eliminated. With the present invention the object to solve those problems is obtained by eliminating the need of making holes in the frame profile.
According to a preferred form of execution of the invented method the clip is displaced to its exact position along the frame profile when, in one or another way, the exact position is determined. By that the dimensions of the clip, i.e. the width of the base surface and the design of the tie-back, are tested to retain the glazing bars in a way that is described above, but are adapted so that the friction and the retaining force isn't too large. The design of the width of the clip and the design of the tie-back manage the task with a selected security margin, but the clip is still movable along the frame profile/weather strip. By assembling this leads to the advantage that the clip can be pressed in place, approximately in its right position, and thereafter be displaced to its exact position, the position that for example is given by the fitting in of the glazing bars.
According to a preferred form of execution of the invented method the clip is used as an guide and a drill guide by the hole making of the frame profile by that the frame profile includes a heightening, a wart, with a through hole, through both the center of the wart and through the base surface. By the height of the wart the hole is given a guiding function so that the drill drills at intended angle through the profile which also results in that for example a drill chuck has free space relative the window surface and also that the fastening elements are guided in right angle for fastening in the frame profile/frame piece. By using the clip as drill guide a protection is at the same time obtained for the surrounding surfaces of the frame profile which are not damaged by the making of holes, which easily can occur by a drill operation made by hand.
According to a preferred form of execution of the invented method the clip is anchored against the frame profile or frame piece with a fastening element, e.g. a nail, screw or pop rivet or the like. This is made possible since the above said form of execution, a wart provided with a hole, is used. By this moment the hole constitutes a guide of the fastening element for fastening at the therefore intended position in the frame profile or frame element. This is advantageous in those cases when a purchaser/house owner desire an additional securing of the clip, for instance by large spans of the glazing bars or another design that makes the glazing bars extra heavy or that the height or the nature of the building is such that an additional securing is desired.
According to a preferred form of execution of the invented method the clip is anchored against the frame profile by means of an adhesive, e.g. a double-stick tape. This is made possible when the base surface of the clip, its length and width is large enough to include the adhesive on the underside of the base surface so that a sufficient anchorage is obtained. Accordingly, both an extra securing in addition to the first preferred form of execution and that the surface of the frame profile don't need to be perforated with a hole is obtained, which is an advantage if a totally dismounting of the glazing bars and the clip is desired according to the object in the previous paragraph.
According to a preferred form of execution of the invented method the clip is totally dismountable, i.e. it will be removed by hand-power from the frame profile. In this form of execution there are no permanent marks from the clip, neither at the weather strip nor at the frame profile. This has the advantages that the house owner without special tools or special knowledge can alter the exterior of the window from provided with glazing bars to without glazing bars without remaining holes in the frame profile or to perform a careful cleaning or restoration of the window or the glazing bars.
The above preferred forms of execution are stated in the dependent claims. The invention is explained in detail by the following detailed description of the example of execution of the invention referring to the accompanying drawings.

Detailed description of the invention

Figure 1a and 1b shows a complete frame piece in form of a window frame with removable glazing bars.
A frame piece 3 which includes a core, preferable of wood. The frame pieces 3 encloses a surface 6, which surface for instance is a window glace or another disc shaped material, depending on if it is a window, a door or another kind of window-like section. The frame piece 3 also includes a casing profile; a frame profile 4, that preferable consists of aluminum, and which is mounted against the frame piece in one or another way. To provide a visual effect that the surface 6 consists of a number of smaller surfaces removable glazing bars 2 is mounted against the surface 6, by snapping the glazing bars 2 against the frame piece. This is made possible by that the frame piece is provided with clips 1 in form of a male element, which clips is mounted against the frame profile 4, and that in the ends of the glazing bars there are a correspondence in form of female elements where the male elements cooperate to retain the glazing bars on the frame profile 4 and are additionally arranged so that the glazing bars are dismountable.
Figure 2a-2d shows detail pictures of the clip in cross section from above and in perspective view. The clip 1 includes a base surface 7, which has a length L and a width B and one first side 13 and one, relative the first side, opposite second side 14. The first side 13 includes a tie-back 8 with a short extension relative the length L of the base surface 7 and where the tie-back 8 has an angular adjustment relative the base surface 7 that preferable is more than 90°. The second side 14 of the base surface 7 includes a center marking 9 in form of a tip. In addition a heightening is provided, a wart 10, preferable at the center of the base surface 7, where the wart 10 includes a through hole 11, which also penetrates the base surface at the bottom of the wart 10. The diameter of the hole 11 is coordinated with a suitably fastening element, for instance a nail, screw, pop rivet or the like. The center axis of the hole 11 has an angle α relative the base surface, that preferable lies in the interval 70-120°. The height H of the wart 10 is arranged so that a sufficient guide of a performable fastening element is obtained. In addition the wart 10 has a tested out chamfer 12 at the side closest to the first side 13, which chamfer preferable is coordinated with height H of the clip 1 in a way that sufficient free space is obtained between the clip in its mounted position and the surface 6, so that a cleaning of the surface 6 is facilitated.
Figure 3a and 3b shows the position of the clip and in detail.
In the figure a part of the frame piece 3 is shown, which is cased with the frame profile 4 and where the frame piece also grips around the surface 6, for instance a window frame, and where between the surface 6 and the frame profile 4 a seal 5 is provided. Since the seal 5 is flexible it is possible for the clip 1 to be pressed in place, whereupon the tie-back 8 comes in engagement around the corner 15 of the frame profile 4, between the frame profile and the seal 5 and that the underside of the base surface 7 will bear on the level of the frame profile. Since the wart 10 has the tested chamfer 12, which cooperate with the height H of the wart, a free space between the clip 1 and the surface 6 arranged in a way that the clip will not make an obstacle by the cleaning of the surface 6, for instance by using of so called window scrapers.
Figure 4a and 4b shows alternative anchorages of the clip in the frame piece with nails or against the frame profile with double-stick tape.
The clip 1 is pressed in place in the same way as is described under figure 3. In those cases when an additional securing of the clip is desired, e.g. by special heavy glazing bars or when additional demands on enhanced security exists, the clip can be further anchored compared to the above, in figure 3 described form of execution.
According to the form of execution in figure 4a the clip 1 is anchored in the frame piece 3 by means of a fastening element 16, e.g. a nail or a screw, alternative in the frame profile 4 with a pop rivet or the like. Before the anchorage a hole 17 has to be made in the frame profile 4, where the fastening element 16 is introduced and is later anchored in the frame piece. Hereby it is by the invention possible to use said clip 1, at first as a drill guide, by that the clip initially is brought to its right position along the frame profile 4, whereupon for instance a drill is introduced through the hole 11 and where the hole 11 then constitutes a guide for the drill under the drill operation and as a positioning for the made hole 17 through the frame profile. Thereafter the fastening element, in the preferred example the nail, is led through the hole 11 and further through the hole 17 in the frame profile 4 and will by that be fastened in the frame piece 3 by means of a therefore appropriate tool, for instance a hammer. By the adapted angle of the hole 11 relative the base surface 7 and accordingly relative the surface 6, which is described under figure 2, the accessibility is facilitated by the drill operation in a way that the drill equipment gets a free space relative the surface 6. This angle is also advantage by the fastening itself of the fastening element, for instance by nailing.
According to the form of execution in figure 4b the clip 1 is anchored against the frame profile 4 by mean of an adhesive 18, preferably a double-stick tape, which has been applied on the underside of the base surface 7 before the mounting of the clip 1 against the frame profile, according to the description under figure 3. When the clip is pressed in place and has, if necessary, been displaced along the frame profile 4 to its exact position, the protective foil on the adhesive is removed and the clip is pressed on the frame profile.
