Description

The The invention relates to an aluminum profile, in particular for Showcases and display cabinets, for sliding of glass and tempered glass.

It It is known that for pushing glass sheets plastic profiles are used, which are circumferentially firmly connected to a metal profile. The disadvantage of using plastic sliding profiles is that the plastic melts in case of fire and the glass pane stops is lost and thus, for example, in corridors and escape routes by dropping the disc an additional source of accident forms. Furthermore, a lateral insertion into the profile only conditionally possible, since the double rails in the same level. By the natural dislocations with tempered glass (ESG) and by inaccurate assembly The mitres push the glass when pushed the vertical profile edges. Plastic profiles are for the replacement unsuitable as it is firmly connected to the metal profile are. Furthermore, it is known that for sliding glass sheets in Showcases extruded aluminum profiles are used, the complete are provided with a color coating, which is a move allows the glass in the first place. D. h., is the color coating by the back and forth only once worn, then the entire product has to be replaced become. Likewise, here is a lateral insertion of the Glass pane in the profile only conditionally possible because the double rails are in the same plane. By the angling will destroy the paint coating and the ESG glass is subject to an even higher risk of breakage, because the delicate glass edge now has a direct contact with the metal profile Has. The use of anodised profiles is a solution not on, because a shift of glass is not possible is. General disadvantage in the described solutions is that wearing parts only very expensive or are not interchangeable. Also roll-mounted fittings will be partially used for pushing glass panes in showcases, However, the increased labor and material costs required do. In addition, a filigree, even, circumferential appearance through the additional running shoe not given.

A solution of the type described is, for example, in the DE 3147061 C2 - Cabinet with at least two sliding doors - published. Here, an element disposed at the rear of each sliding door is formed as a continuous rail extending along the lower edge of the sliding door, and the space thereof is formed as a channel having at least two rollers. Also the DE AS 2700648 shows a sliding door, which consists of a mirror, a glass or similar material. The recesses required to move the sliding door here also include the storage for the rollers, continue to form the conclusion of the running shoe consisting of the profile strips and contribute to the enclosure of the sliding door in the edge area.

The The object of the invention is a cost-effective Variant for pushing glass panes in showcases u. ä. to develop a high stability, reliability in case of fire and above all an interchangeability of all wearing parts allows.

The Solution of the task is carried out according to the im Claim 1 specified characteristics.

• – Im Brandfall ist kein Herausfallen von Glas möglich, da der Rundstab (PTFE-Teflon) bis 260°C dauerwärmebeständig ist und anschließend bei noch höherer Temperatur mit der Glasscheibe verklumpt. Der Schmelzpunkt von der Aluminiumführungsschiene liegt bei mindestens 600°C.
• – Das Kunststoffführungsprofil und der Rundstab, also alle Verschleißteile, sind austauschbar, daraus resultiert die Langlebigkeit der Gesamtkonstruktion.
• – Die Gesamtkonstruktion ist material- und lohnkostensparend, da die Herstellung mit nur einem Metallprofil, einem Kunststoffführungsprofil und einem Rundstab möglich ist.
• – Das seitliche Einfahren der Glasscheibe ins Metallprofil ist ohne Probleme möglich, da das Kunststoffprofil nur oben und unten eingeklickt wird und somit die Materialstärke des Kunststoff-U-Profils seitlich als Toleranzausgleich dienen kann.
• – Alle farbigen und eloxierten Oberflächen sind möglich.
• – Gleiche umlaufende, wohlwollende und filigrane Profilschicht entsteht.
• – Eine hochwertige stabile äußerliche Metallausführung, da das Kunststoffprofil nur verdeckt (hinter den halbrunden Sperrnasen) zum Einsatz kommt.

The proposed solution is characterized in particular by the following advantages:

• - In case of fire, no falling out of glass is possible because the round rod (PTFE Teflon) up to 260 ° C is resistant to permanent heat and then clumps at even higher temperature with the glass. The melting point of the aluminum guide rail is at least 600 ° C.
• - The plastic guide profile and the round rod, so all wearing parts, are interchangeable, resulting in the longevity of the overall design.
• - The overall construction is material and labor costs saving, since the production with only a metal profile, a plastic guide profile and a round rod is possible.
• - The lateral retraction of the glass into the metal profile is possible without any problems, since the plastic profile is only clicked up and down and thus the material thickness of the plastic U-profile can serve laterally as a tolerance compensation.
• - All colored and anodized surfaces are possible.
• - Same circumferential, benevolent and filigree profile layer arises.
• - A high-quality stable external metal design, since the plastic profile is used only concealed (behind the semicircular locking lugs).

Consequently This solution forms a whole unit and can be integrated into many other products by gluing, screwing and clicking to get integrated.

The The invention will be described in greater detail below with reference to a drawing explained.

It shows:

1 a cross section of the aluminum profile - upper and lower guide -

2 an overall view of a complete Showcase window with cut AB to 1

The proposed solution consists of an extruded and torsion-free aluminum profile 1 and is a double U-track in the lead-in area with semicircular locking lugs 2 provided in this aluminum profile 1 is each a plastic U-profile 3 , above and below, to guide the glass, clicked. In the two lower halves of the plastic U-profile 3 are each plastic bar profiles 4 over locking lugs 5 also clicked.

The viewing area of the aluminum profile 1 is the same all around and serves a uniform, necessary for the purpose, appearance.

So that glass panes 6 in aluminum profile 1 easy to push at all, is the clicked plastic profile 3 necessary, which however also additionally in the aluminum profile 1 can be screwed or glued.

It is advantageous for the quick and easy, later interchangeability of the Einklickmöglichkeit the plastic profile 3 , Usable z. As polyethylene and Teflon, both thermoplastic materials with respect to their good properties, such as low wear and a waxy surface. So that the plastic profile 3 secured in the upper area and can not fall out, are as a simple and inexpensive variant semicircular locking lugs 2 incorporated into the aluminum guide area. The overall construction can also consist of only one profile, so that the locking lugs 2 are located circumferentially. The plastic profile 3 is always dimensioned larger than the actual locking lugs 2 , Since the glass sheets must be removable on the one hand, they are first threaded up and then placed down in the same plane. The plastic bar profile 4 As a round rod is made of Teflon and is necessary so that the glass does not tip out of the upper guide again. Likewise, if possible, select a material thickness which has half the height of the guide profile. Thus, the glass is guided up and down at the same height to the opening. The use of plastic bar profiles 4 As a round bar, it has the additional advantage that the natural accumulation of dust can only settle on a relatively small point of contact between glass and plastic. That is, the dust plays only a minor role in natural wear, especially since the sliding resistance to a flat material is low.

at Use of tempered toughened glass comes in addition the natural fault that occurs when curing the Glass arises, added. This Fault (Glass Vault) can cause the wear faster entering as expected. It is therefore important, exactly these wearing parts fast and uncomplicated exchange so that the whole of the product remains unaffected.
