Description

The present invention relates to a Gleitelementvorrichtung, in particular Schiebewand- or balcony railing glazing device, with sliding in a sliding plane sliding elements with lower edge and upper edge, further connected to at least the lower edge rolling bodies which engage in an associated lower profile, usually run therein, and with a rolling body-free formed upper edge of the sliding element, which only has at least one fixed side guide in an upper profile, wherein the two profiles are variable in width and modular and serve for connecting associated profile pieces each tongue / groove connections.

The rolling elements usually provide for a guide of the sliding elements in the respective profile and / or for receiving their weight, which is introduced by virtue of the lower profile in the masonry.

A slider device of the structure described in the opening paragraph is described in US Pat. No. 1,945,008. Here, the structure of the individual profiles is difficult.

This is known from DE 197 53 219 A1 a guide device for sliding elements. At least one first and at least one second profile are designed as first or second extension profile and have associated connection areas. In this way you want to participate as few profiles as diverse applications can be mastered.

In addition, there are many known sliding element devices, for which only reference is made, by way of example, to EP 0 902 153 A2, CH 671 068 A, CH 600 111 A and WO 92/17673 A1. In the prior art, the procedure is consistently that in addition to the described lower profile mandatory an upper profile is provided and carry both the upper edge and the lower edge of the respective sliding roller bodies, which engage in the associated profiles. This is the only way to be able to master the sometimes considerable weights and at the same time impeccable leadership. In addition, occur in Gleitelementvorrichtungen that are placed outside, forces in the sideways direction, which are mostly due to wind or rain. These too must be mastered.

Briefly and well, the state of the art at this point requires consistently the top and bottom roller guide of the movable sliding elements. This is expensive, if only because both the upper edge and the lower edge of the sliding element must be equipped with associated rolling elements. In addition, the rolling bodies adapted profiles are to be assigned. This results in further problems. Because the smooth running of the movable sliding elements in the sliding plane requires that the profiles are straight, so that the rolling bodies move forward without jamming. Such a profile of the profiles can not always be guaranteed, especially not when old buildings are rehabilitated.

This can essentially be attributed to the fact that usually the upper profile is connected to a balcony located above the balcony to be covered, while the lower profile rises on the balcony to be equipped. Such problems have been tried in the past by the fact that the upper and possibly the lower profile were relined accordingly in order to represent the desired straight-line course. Even such an approach is extremely expensive. - Here the invention aims to provide a total remedy.

The invention is based on the technical problem of further developing a sliding element device of the structure described at the beginning in such a way that assembly is facilitated with a simple and cost-effective construction. In addition, an adaptation to a variable number of sliding elements is to be made possible.

To solve this problem, the invention proposes in a generic sliding element device, that the respective tongue and groove joint has a joint-like profiling as a spring and a pan-like profiling as a groove, both traversed in profile rail longitudinal direction and cause axial bearing of the profile pieces with joint play each other.

The side guide for the rolling body-free trained upper edge of the sliding element is mostly about one or more guide rails, which are preferably flexible. Usually serve to side guide the upper edge of the sliding brush strips. These are characterized by the fact that they are equipped with brushes whose weave density increases from the slider starting up to the brush-carrying bar. As a result, the brush strips set the sliding element against increasing wear with increasing wear.

There are mostly two guide rails or brush strips realized that receive the slider between them. Both guide rails can be advantageously arranged on an upper profile. This can for example be done so that the guide rails are inserted into corresponding longitudinal grooves of the upper profile. It must be ensured that the sliding element dips with its upper edge at least as far between the two guide rails, that even with maximum lateral forces and associated deflection of the sliding element slipping out of this quasi double fixed side guide is prevented.
Thus, in such load cases and the associated tensile and compressive forces due to wind (and / or rain), the lower edge of the sliding element is not removed from the associated lower profile, it is provided to equip this lower edge with at least one barb, which overlaps at least one approach or a running rail for the rolling body. In general, two barbs are realized, which surround in the manner of a clip formed from two lugs or projections a T-shaped head of the track rail on both sides. This T-shaped head may be mushroom-shaped on its surface if a roller with a concave tread adapted thereto is used as the rolling element. Such a roller then reciprocates in a vertical orientation with its concave running surface on the mushroom-shaped head in the longitudinal direction of the profile.

The barb may be part of a profile insert connected to a lower frame part. This profile insert is preferably designed as a zinc die-cast part and can be latchingly connected to the lower frame part, which in turn receives the lower edge of the sliding element.

Of particular importance is the fact that the two profiles for receiving the one hand, the guide rails, on the other hand, the rolling body can be variable in width and modular. For this purpose, respective edge pieces and intervening middle pieces of any number are provided so that the bottom line a freely selectable number of sliding elements with the aid of the two guide rails can be performed herein. In this way, the two profiles or guide profiles can be arbitrarily broadened, so theoretically unlimited sliding elements are taken in between.

As a result, any length of glazing lengths can be realized.

For connection of the individual profile parts or edge pieces and centers each groove / spring connections are provided. The spring is designed as a profile rail longitudinal axis continuous joint-like profiling. In contrast, the groove is a ladle-like profile running through in profile rail longitudinal axis.

The tongue and groove connection made possible by their axial bearing not only a quasi horizontal connection of the individual profile pieces or edge pieces and centerpieces, but also a contrast oblique connection. To realize the tongue and groove connection, the respective profile parts in front of the head must be axially displaced or threaded against each other. The joint play is designed so that a slight push against each other is possible.

Although aluminum extrusion profiles are usually used for the realization of the two profiles or profile rails, the assembly described succeeds without problems. This can essentially be attributed to the fact that the profiles in question are equipped before their assembly with a coating, in particular powder coating, which ensures the required lubricity. Of course, alternatively or additionally, lubricants can be used.

In order to determine the tongue and groove connection and attachment of the profiles, fastening means or fastening bolts which engage through the tongue and groove connection are provided in each case. These fastening bolts or means can be arranged offset and direct the resulting forces directly into a masonry or an associated stand construction, in which anchored the fastener and to which consequently the profiles are attached. Consequently, the total forces associated with the dead weight and lateral forces of the Gleitelementvorrichtung not attack on the joint, but rather are introduced via the fastening means or the fastening bolts in the masonry or the stator construction.

Finally, the described profiles are suitable for accommodating additional equipment. This may be an awning, a fly screen, etc. act. For this purpose, usually the respective edge pieces of the rail can be replaced by free-form special profiles. These special profiles then pick up insect screens, shading systems, awnings etc.

As a result, a sliding element device is provided within the scope of the invention, which first of all impresses with a particularly simple and inexpensive construction. This can essentially be attributed to the fact that rollers or rolling elements are expressly not required at the upper edge of the sliding elements, but rather a fixed (one- or) two-sided lateral guide is used. Characterized in that the upper edge of the respective sliding element by a predetermined amount between the two Side guides immersed, deflections of the slider can be easily mastered. Such deflections usually occur as tensile or compressive forces, which are directed vertically to the associated element level and can be attributed to wind or rain pressure. Briefly and well, the sliding element device described by functional reliability at the same time simple and inexpensive construction.

In addition, the assembly is much easier. This can also be attributed to the roller body-free formed upper edge of the sliding element. Because now it is not (anymore) necessary to absolutely have to provide for a straight course of the upper profile. The same applies to the lower profile. The relining measures described in the prior art can thus largely be dispensed with. This makes assembly easier and cheaper.

The sliding elements are usually sliding glass elements with a so-called cold glazing. That is, of associated frame parts, only a simple glass pane is held, which may be designed as a safety glass pane. This sliding glazing is particularly suitable to be built on balcony railing or parapets. Likewise, of course, the cultivation of substructures is conceivable. In any case, this can extend the use of an associated balcony seasons independent. At the same time, the overall thermal insulation of the building is increased. Of course, the described Gleitelementvorrichtungen also limit or covering of terraces, swimming pools, etc. are used. Likewise, of course, also offers an attachment and operation inside. Then the sliding elements are usually designed as wood (veneer) plates.

In the figures, a Gleitelementvorrichtung is shown, which is in the context of the embodiment is a balcony railing glazing device. This can be mounted between two indicated only in Fig. 1 balconies 1. The basic structure includes sliding elements 2, which are sliding glass elements. These sliding elements 2 move in Substantially in a particular in Figs. 3 and 4 schematically indicated slip plane G. Here the addition "essentially" expresses that can also represent branches, switches, minor bends, etc., as exemplified in the EP 0 902 153 A2 will be described in detail.

The sliding elements 2 have at their lower edge 3 connected rolling elements 5, which engage in an associated lower profile 6. The upper edge 4 of the sliding elements 2 engages in a profile, namely an upper profile 7. However, this profile 7 is not mandatory. Because the upper edge 4 of the sliding member 2 is formed according to the invention rolling body free and has only at least one fixed side guide 8. In the context of the exemplary embodiment, this side guide 8 is a guide rail, which is designed as a flexible brush strip 8 (see FIG. 2).

Basically, this brush strip 8 can be attached to any ceiling construction, as long as it is ensured that the upper edge 4 of the sliding element 2 is thereby guided properly sideways. In the context of the example shown, two guide rails 8 or brush strips 8 are realized, which receive between them the sliding element 2 immersed in the gap S formed thereby, or its upper edge 4. The upper edge 4 of the sliding element 2 is immersed by a predetermined amount M in this gap S in order to take into account possible deflections of the sliding element 2. It is understood that that Dimension M takes into account the maximum occurring lateral deflections of the sliding element 2.

The guide rails or brush strips 8 are slidably received in sliding grooves 9 of the upper profile 7, which - as I said - is not mandatory. In contrast, the already mentioned rolling elements 5 are realized at the lower edge 3 of the sliding element 2. These are vertical rollers 5 with concave tread 10. In this way, a perfect running of the rollers or rolling elements 5 on a mushroom-like tread 11 is ensured. The curvature of the mushroom head is adapted to the concavity of the tread 10.

Each of two on both sides of a subsequent web 13 projecting lugs 12 form a T-shaped head of the running rail 11, 12, 13. The two lugs 12 are of two barbs 14 on the lower edge 3 of the sliding element. 2 enclosed in the manner of a clip on both sides. In this way, even with deflections of the sliding element 2, the roller 5 is prevented from lifting off the associated running surface 11 or the running rail 11, 12, 13. The barb 14 is part of a profile insert 16 connected to a lower frame part 15.

This profile insert 16 is designed as a zinc die-cast part and is inserted into the associated frame part 15. An upper frame part is missing, because the sliding element 2 or the glass pane is held free at this point between the two guide rails 8.

Of particular importance is the fact that the lower profile 6 and the upper profile 7 and the associated profile rails 6, 7 are made wide variable and modular. This is particularly evident in Figs. 3 and 4 expressed. Here it can be seen that both profiles 6, 7 are ultimately composed of edge pieces 17a, 17b and middle pieces 18a, 18b. In this case, virtually any number of center pieces 18a, 18b can be positioned between the respective edge pieces 17a, 17b. This has the consequence that the number of rails 11, 12, 13 and the number of guide rails 8 can be made variable. As a result, virtually any number of sliding elements 2 can be accommodated and guided between the associated profiles 6, 7.

In order to be able to connect the edge pieces 17a, 17b to the middle pieces 18a, 18b, groove / tongue connections 19, 20 are provided in each case. These groove / spring connections 19, 20 have a joint-head-like profiling and running in the longitudinal direction of the profile rail. In contrast, the groove 20 is a ladle-like profile running through in the profile rail longitudinal direction.

Consequently, the respective profile pieces 17a, 17b and 18a, 18b must be combined in front of the head by axial telescoping together. Here, an existing and in FIGS. 3 and 4 recognizable joint play ensures that a slight push against each other of the profile pieces 17a, 17b and 18a, 18b is made possible. Supportive acts here The fact that the profile pieces 17a, 17b and 18a, 18b are equipped with coatings which promote the sliding against each other.

Thus, the individual profile pieces 17a, 17b and 18a, 18b have the required support with each other, a fastening means 21 is provided which engages at least at one point by the respective tongue and groove connection 19, 20. The fastening means 21 is a fastening bolt 21 which is anchored in the masonry 22. It can be seen on the basis of FIG. 3 that over the length of the profiles 6, 7 or profiled rails 6, 7 a plurality of fastening bolts 21 are used, which are arranged offset to one another. - Of course, the profiles 6, 7 also on a stand construction - and not a masonry 22 - are fixed.

Finally, Figs. 5 and 6 illustrate that the profiles 6, 7 and for receiving additional devices, such. B. awnings 24, fly screen blinds 23 etc. are set up. For this purpose, the respective edge piece 17a, 17b of the profile 6, 7 is replaced by a special profile. In the context of FIG. 5, the special profile shown there takes up a merely indicated fly screen or fly screen 21. In the variant of FIG. 6, the additional attachment of an awning 24 is possible.

The profiles 6, 7 are aluminum extrusion profiles. In contrast, as a frame part 15 mostly a plastic hollow profile is used. The individual sliding elements 2 are usually free within the profiles 6, 7 push back and forth. But it is also conceivable to block their sliding movement either. For this purpose, the invention proposes to realize a spring-loaded linkage on each slider 2, the upper and lower pins only then non-blocking retract into the respective profile 6, 7 when a button, lever, etc. is pressed.

For the necessary ventilation of the closed behind the Gleitelementvorrichtung space anyway present column in the lower profile 6 respectively upper profile 7. Also between the individual sliding elements 2 usually stomata are provided. Of course, these stomata can be closed as desired by sealing lips, if a windproof cover is desired.
