GLAZING BAR AND GASKET FOR USE WITH A GLAZING BAR

Abstract: Glazing bar (1) for mounting on the surface of a glass plane, which glazing bar (1) comprises a sectional piece (2) and a gasket (3) forming part of the sectional piece, which sectional piece (2) comprises a plate (6), from whose back side (5) at least two, preferably four, longitudinal partitions (4) emerge to create at least one, preferably two, channels (7), in which channel(s) (7) the gasket (3) is arranged. Each partition (4) is terminated by a projecting pin (8) which is substantially parallel to the surface of the plate (6) and which point towards the centreline of the channel, creating a partially bound cavity. A glazing bar may thus be obtained into which the gasket can be placed without any binding agent, so that an adhesive medium is only required for the actual mounting on the surface of a glass plane.

Description: GLAZING BAR AND GASKET FOR USE WITH A GLAZING BAR The invention relates to a glazing bar for mounting on the surface of a glass pane, which glazing bar comprises a sectional piece and a gasket forming part of the sectional piece, which sectional piece comprises a plate, from whose back side at least two, preferably four, longitudinal partitions emerge to create at least one, preferably two, channels, in which channel (s) the gasket is arranged. The invention also relates to a gasket for use with a glazing bar. It is common to fashion glazing bars which are to be mounted on panes, for example windows and/or doors, in such a way that they are given a design on their side facing away from the pane which is preferably the same as the form on the original window and/or door frames, so that the window and/or doorframes, together with the mounted glazing bar(s), appear to be a single unit. An example of such a glazing bar is provided in European patent application number 94104817.5. On the side facing away from the pane, the glazing bar comprises a surface with two edges which are deflected toward the pane and which, depending on the mounting of the glazing bar, respectively form an upper edge with an associated lower edge, or a left edge with an associated right edge. As an additional refinement, a projection is placed on each of these associated edges, so that the back side of the glazing bar is concealed. On the opposite side of the glazing bar, the side facing the pane, channels are formed along the entire length of the glazing bar to create two partially bound cavities. These cavities form the glazing bar's mounting system. The actual mounting of the glazing bar occurs with the help of another glazing bar, an inner glazing bar, which is mounted onto the window and/or doorframes by the use of pins inserted into said window and/or doorframes . There are incisions arranged along the entire length of the inner glazing bar, and the entire piece is connected by laying the outer glazing bar over the inner glazing bar in such a way that its cavities are interlocked with the incisions on the inner glazing bar. Therefore, more than a single glazing bar is required for this assembly, as there is no specific binding agent provided between the pane and the glazing bar. Thus, a very precise and/or pliable glazing bar is required both to prevent it from exerting unnecessary pressure on the pane and so that it does not create gaps allowing dirt/grime to accumulate between the inner glazing bar and the pane. Based on other systems, it is common to manufacture a glazing bar of the sort mentioned in the introduction. It is mounted with a gasket, which essentially comprises a double-sided adhesive that sticks both to the channel (s) arranged on the glazing bar and to the pane. However, this assembly requires that the channel (s) of the glazing bar be carefully cleaned before the gasket is adhered in order to prevent the accumulation of dirt/grime on the channels (s) located on it so that the glue does not crack and the gasket does not become loose. Thus, this mounting process itself becomes time- consuming. The object of the invention is to provide a glazing bar which solves the aforementioned problems, by which the glazing bar can be mounted directly on the pane and also by which the design of the glazing bar ensures that the gasket can be mounted quickly and efficiently to said glazing bar without the use of adhesive agents. The object is achieved by a glazing bar of he type mentioned in the introduction, whereby each partition is terminated by a projecting pin which is substantially parallel to the surface of the plate and is pointing towards the centreline of the channel, creating a partially bound cavity. Thus, the product functions by inserting the gasket into the partially constructed cavity on the glazing bar, and then removing the strip covering the glue on the gasket . The glazing bar can then be mounted onto the corresponding pane by using the adhesive element. The projecting pins facing the centreline of the channel ensure that the gasket itself, which is pressed down into the glazing bar's channel, will not slide out of the channel due to the adhesive effect. It is to be noted that the gasket, as indicated in Claim 7, may also be equipped with similar pins, so 'that the channel pins will catch on the pins of the gasket, which completely guarantees the mounting of the gasket in the channel. It is also to be noted that, due to the selected hardness of the gasket, it is not possible to remove the mounted glazing bar from the gasket by pulling it. If it is pulled forcefully enough, the slippage that occurs will be between the glass and the glued surface. By providing a glazing bar according to the invention, and furthermore as indicated in Claim 2, is obtained that no gaps may arise between the glazing bar and the pane, thereby preventing the accumulation of dirt/grime. By providing a glazing bar according to the invention, and furthermore as indicated in Claims 3 and 4, is obtained that any unevenness in the connection of the materials is eliminated, while at the same time retaining a certain hardness to establish a stable mounting of the gasket in the channel/channels . By providing a glazing bar according to the invention, and furthermore as indicated in Claim 5, is obtained that the hard part can slide and be fixed in the channel, while the soft part makes an even and level connection to the glazing bar, gasket, or pane, respectively. In addition, the glazing bar can be immediately reused if the gasket is replaced, since the glazing bar does not need to be cleaned of any residual glue. By providing a glazing bar according to the invention, and furthermore as indicated in Claim 6 , is obtained a appropriate hardness for the two gasket elements, determined based on their respective functions. By providing a glazing bar according to the invention, and furthermore as indicated in Claim 7, is obtained a locking mechanism perpendicular to the surface, whereby the gasket can basically only be removed by sliding in the longitudinal direction of the glazing bar. By providing a glazing bar according to the invention, and furthermore as indicated in Claim 8, a simple glazing bar is obtained that actually does not require any form of maintenance, while at the same time it is inexpensive and easy to manufacture. The invention also relates to a gasket as indicated in Claims 9-13, which is especially well suited for use with the glazing bar according to any one of Claims 1-8. The invention will now be described in greater detail with reference to the figures, where Fig. 1 shows a cross-section of a first embodiment of a glazing bar according to the invention with a gasket inserted, Fig. 2 shows a cross-section of a second embodiment of a glazing bar according to the invention without a gasket inserted, Fig. 3 shows a detailed picture of the glazing bar shown in Fig, 2 with a gasket, Fig. 1 and 2 show a cross-section of a glazing bar 1, together with an associated gasket 3 according to the invention in the case of Fig. 1. This glazing bar 1 is manufactured of a light metallic material, preferably aluminium. However, the glazing bar 1 may also be manufactured of other suitable materials, e.g. wood, plastic, or composites of any of the aforementioned materials. The choice of material will normally depend on the other materials used in the window. Both Fig, 1 and 2 shows a glazing bar 1, which is to be mounted onto the surface of a glass pane to give a smooth glass pane the appearance of a so-called "farm pane", i.e. a pane that is divided into sections by using longitudinal and/or diagonal glazing bars, for example. Generally, this involves a traditional window design with a fixed main frame and. an movable frame in which a glass pane or a filling is located. This means that the assembly of one or more glazing bars will produce a division of the pane or the filling into two or more compartments or fields. The glazing bar 1 comprises a sectional piece 2 and a gasket 3 belonging to the sectional piece. The sectional piece 2 comprises a plate β, which is normally oblong, substantially thinner than both length and width. The plate 6 has a front side 15 and a backside 5, which may comprise a pair of projecting elements 16 angled in an - shape which are used to attach any additional cut sectional pieces by means of familiar mounting mechanisms. Said L-shaped elements emerge from the back side 5 of the plate 6. On the back side 5, at least two more, preferably four, longitudinal partitions emerge. These partitions 4 are arranged in such a way that a channel, which preferably has a width of 10 mm, is formed between two partitions. These two channels will preferably be arranged symmetrically around the centreline of the sectional piece, so that the channels are set at some distance from there and are preferably as shown along the free edges of the sectional piece. As mentioned, the channels are created by longitudinal side elements . These side elements can be provided as indicated in Fig. 1 by a plate part 14 emerging from the backside 5 of the plate β, from which plate part 14 the two partitions 4 emerge. The partitions 4 turning inward toward the centre axis of the sectional piece are at a 90* angle with respect to the backside, whereas the outermost partitions preferably form an obtuse angle of about 15-25* . In Fig. 2, this auxiliary element 14 is omitted, and thus the partitions 4 emerge directly from the backside 5 of the plate 6. Thus, it is essential to the invention that these partitions 4 preferably each end as indicated in a continuous, longitudinal flange, projection, or pin 8 projecting toward the centreline of the channel, thereby creating a partially bound cavity. It is partially bound, because the cavity thus has a base and sidewalls, while the actual ceiling is open, sin'ce it consists exclusively of said pins, which are arranged so that there is a distance of approx. 6-7 mm between the longitudinal pins for each individual channel. The pins 8 may also have other geometric shapes, for example open breaches in a longitudinal direction at appropriate intervals . A gasket 3 is then arranged in each of the cavities created. This gasket 3 is described in greater detail below. It is also to be noted that the pins 8 of the partitions 4 have a lower surface 13 facing the backside of the plates. This surface will be adjacent to the flanges, projections, or pin elements 18 of the gasket mentioned, as may be seen by examining the gasket. The gasket 3 of the glazing bar is manufactured of a rubber material or similar material and, as indicated, it preferably comprises a first gasket element 11 and second gasket element 12, whereby these also preferably have different levels of hardness. The first gasket element 11 is designed for insertion into the partially bound cavity of the glazing bar; therefore; it is manufactured of a rubber material with a hardness 'that functions to ensure that it cannot be removed from the cavity directly or unintentionally by a pull. Thus, the first gasket element is manuf ctured of a harder . ubber material than ' the second gasket element 12, which is located entirely or partially outside of the cavity. The hardness of the first gasket element 11, the first hardness, is in the range of [60-100] Shore, while the hardness of the second gasket element 12, the second hardness, is correspondingly in the range of [40-70] Shore. Suitable material may include Santopren ®, EPDM, PVC, and other similar materials. The difference between the soft and hard gasket elements in a given gasket 3 must be at least 10 Shore, where the Shore values are based on the same scale. As indicated, said first gasket element 11 comprises projecting pin elements 18 along its entire length, the lower surface 10 of which is adjacent to the surfaces 13 of the pins 8 facing the interior of the cavity. Because of the hardness of the first gasket element 11, the gasket 3 can be placed into the partially bound cavity of the glazing bar by sliding it along the partially bound cavity- A certain elasticity of the first gasket element may be ensured by a hollow space 20 in its centre, which contributes to easier insertion/mounting within the cavity, The pins 18,8, both on the first gasket element 11 and on the partitions 4, respectively, will produce a locking effect, whereby the gasket cannot be directly removed in a direction perpendicular to the longitudinal direction of the glazing bar. The shape of the first gasket element 11, in conjunction with the hardness of the material, will thus make it possible to avoid gluing or other time- consuming fixing processes, while at the same time creating a tight connection between the gasket element 11 and the cavity of the glazing bar, which then may be kept free of dirt/grime. The second gasket element 12 is arranged as a direct extension of the first gasket element 11 on the side facing away from the partially bound cavity. It encloses the outer surfaces 17 of the lateral pins and partially encloses the first gasket element 11. An adhesive agent 9 is placed on the second gasket's free surface in order to mount the glazing bar 1 onto the surface 1 of a glass pane. The selected hardness of the material, the second hardness, ensures that the glazing bar 1 will remain pliable after mounting, while it will still have a dampening effect on any forces exerted on it from the outside, for example in connection with cleaning the glazing bar and/or window. Fig. 3 shows a detailed picture of the gasket mounted in the channel, from which the interaction between the channel pins 8 and the pins 18 of the hard gasket element may be seen.
