Die Neuerung betrifft eine Stuhlarmlehne mit einem Ü-Proiil und mit im Profilinnenraum angeordneter keilförmigen Höckern zur tastung der Stuhlarmlehne.The innovation concerns a chair armrest with an Ü-Proiil and with wedge-shaped bumps arranged in the profile interior for palpation of the chair armrest.
Bei bekannten Stuhlarmlehneη sind die Hocker beidseitig an den [nnenkanten des U-Profils jeweils einander gegenüberstehend ausebildet. Entsprechend rastet das Arretierstück in die paarweise usammengehörigen Hocker an beiden Innenkanten ein. Die Anordnung der Hocker an den Innenkanten führt zu erheblichen \7andätärken. Dieses ist bekanntlich bei Spritzgießteilen nachteilig. Jm Einfallstellen zu begegnen, benötigt man in der Praxis den usatz eines Treibmittels, Dieses Treibmittel bedingt in der ertigen otuhlarmlehne Schlieren und Flecken» Aus diesem Grund st es nicht möglich, Stuhlarmlehnen aus eingefärbten Thermoplasten herzustellen, weil diese Schlieren und Flecken die Stuhl-Armlehnen unansehnlich machen.In known Stuhlarmlehneη the stools are on both sides of the [inner edges of the U-profile each formed opposite one another. Accordingly, the locking piece engages in the stools that belong together in pairs on both inner edges. The order the stool on the inner edges leads to considerable thickness. This is known to be disadvantageous in the case of injection molded parts. To counter sink marks, you need the in practice Addition of a propellant, This propellant causes streaks and stains in the finished otuhlarmrest »For this reason it is not possible to use colored thermoplastic armrests because these streaks and stains make the chair armrests make unsightly.
ufgabe der Neuerung ist eine fertigungsgerechte Gestaltung der ituhlarmlehne.The task of the innovation is a production-ready design of the chair armrest.
3iese Kufgabe wird nach der feuerung dadurch gelöst, daß die eilförmigen Hocker auf der Mittellinie des Mittelstegs des J-Profils angeordnet sind.3 This task is solved after the firing by the egg-shaped stools are arranged on the center line of the central bar of the J-profile.

Es erweist sich, daß die Anordnung; der keilförmigen Höcker auf der Mittellinie des Mittelstegs eine ausreichende Stabilität liefert, so dall eine sichere Rastung durch das Arretierstück möglich ist.It turns out that the arrangement; the wedge-shaped hump on the center line of the central bar provides sufficient stability so that the locking piece can be securely locked into place.
In weiterer Ausbildung der Neuerung ist vorgeschlagen, daß jeder Höcker zwei parallele Keilwände und eine die Scheitel der Keilwände verbindende Querwand umf.-.ßt.In a further development of the innovation, it is proposed that each hump should encompass two parallel wedge walls and a transverse wall connecting the apices of the wedge walls.
Durch diese Ausbildung der Höcker hat man auch im Bereich der Höcker nur dünne Wandstärken, was für die Verfestigung und spannungsfreie Abkühlung des Werkstücks außerordentlich günstig ist. dadurch kann die Jtandzeit kurz gehalten werden» Die Neuerung ermöglicht es, Stuhlarmlehneη in beliebigen Farben durch eingefärbte Thermoplast herzustellen. Der Zusatz eines Treibmittels ist nicht erforderlich.As a result of this design of the humps, wall thicknesses are only thin in the area of the humps, which is extremely beneficial for the solidification and stress-free cooling of the workpiece. thereby the Jtandzeit be kept short "The innovation makes it possible to produce Stuhlarmlehneη in any color by colored thermoplastic. It is not necessary to add a propellant.
Eine Ausführungsforn. der feuerung wird im folgende unter Bezugnahme auf ei ie anliegende Zeichnung erläutert, in der dar-An execution form. the firing is referred to below explained on an attached drawing, in which
Fig. 1 eine Stuhlarmlehne in teilweise aufgebrochener und abgebrochener Ansicht,1 shows a chair armrest in a partially broken and broken view,
Fig. 2 eine Unteransicht zu Fig. 1 undFig. 2 is a bottom view of Fig. 1 and
Fig. 3 einen Schnitt nach der Linie III-III in Fig. ?. 3 shows a section along the line III-III in FIG .
Die Stuhlarmlehne hat ein U-Profil aus einem Mittelsteg 1 und zwei Schenkel 2. Die beiden Schenkel 2 sind durch eine Stirnwand 3 miteinander verbunden. Am Hinterende 4 der Stuhlarmlehne ist ein Durchgang 5 für einen Gelenkzapfen zur Befestigung an der Rückenlehne vorgesehen.The chair armrest has a U-profile made up of a central web 1 and two legs 2. The two legs 2 are connected to one another by an end wall 3. At the rear end 4 of the chair armrest, a passage 5 is provided for a pivot pin for attachment to the backrest.
Die Schenkel 2 sind durch rahmenartige Stege 6 ausgesteift.
Außerdem sind zur Versteifung der Stuhlarmlehne Querstege 7 vorgesehen. The legs 2 are stiffened by frame-like webs 6.
In addition, crossbars 7 are provided to stiffen the chair armrest.
Längs der Mittellinie des Mittelstegs 1 sind nach der Erfindung Höcker 8 angeordnet, die jeweils aus zwei parallelen Keilwänden
9 und einer die Scheitel der Keilwände verbindenden Querwand 10 bestehen. Diese Höcker ermöglichen eine Rastung mit Hilfe eines
Arretierstücks, um die Stuhlarmlehnen und damit die Rückenlehne in verschiedene Stellungen einstellen zu können. Durch die Anordnung
und Gestaltung der Höcker in der Mittellinie des Mittelstegs erreicht man, daß die Wandstärkender Stuhlarmlehne überall
nahezu gleich sein können, was spritztechnisch außerordentlich
wichtig ist. Infolgedessen kann die Stuhlarmlehne nach der Neuerung ohne Treibmittel aus einem Thermoplast gespritztwerden.
Damit ist auch die Verwendung eines eingefärbten Thermoplaste
möglich, so daß nach der feuerung Stuhlarmlehnen beliebiger
Farbe hergestellt werden können.According to the invention, cusps 8 are arranged along the center line of the central web 1, each of which consists of two parallel wedge walls 9 and a transverse wall 10 connecting the apices of the wedge walls. These humps allow a locking with the help of a locking piece in order to be able to adjust the chair armrests and thus the backrest in different positions. The arrangement and design of the humps in the center line of the central bar ensures that the wall thicknesses of the chair armrests can be almost the same everywhere, which is extremely important in terms of injection molding. As a result, according to the innovation, the chair armrest can be molded from a thermoplastic without a propellant. This also allows the use of a colored thermoplastic
possible, so that any chair armrests after the fire
Color can be made.
