DE1083519B - Curtain gliders made of hardwood soaked with resin-free oil - Google Patents

Description

GERMAN

The invention relates to a curtain glider made of hardwood impregnated with resin-free oil with in the Direction of movement of the curtain swinging hook or eye-shaped hanger.

Curtain gliders made of hardwood soaked in paraffin do not make any noise and have become proven especially for theater curtains on wooden slide rails. However, it has been found in attempts Wooden sliders also shown to run on metallic slide rails, as did the bearing journals stick the curtain hook through the paraffin and make grooves, inhibit sliding and Noise or even breakage can cause annoying and time-consuming replacement of the glider condition. With these known curtain sliders, obstructions and breaks in the slider are easy and quickly exchangeable curtain hooks to prevent the curtain cord from being thrown out of the hook eye when closing or opening the curtain to avoid tapering below the slide rail Glider end stored. The free upwardly curved hook leg is between the end of the slider and the free hook shank and forms a narrow threading gap with the slider for the curtain cord. The curtain cord can be between the inside of the free hook end and the their adjacent side of the end of the slider can be easily inserted. That by the pulling force of the curtain cord and the torque generated by the inertia of the curtain has an inhibiting effect on the sliding movement of the thereby tilting or hopping glider. While it is common knowledge, curtain hooks and hang up eyelets above the sliding surface and close to the direction in which the curtain cord is pulled. But there is in these known curtain supports, especially when using the usual im Cross-section I-shaped slide rail has the disadvantage that the curtain slider consists of two curtain slider halves consists, which are connected to each other by a closed loop, the above-mentioned for curtain supports Bring disadvantages.

Mainly with arched slide rails for theater curtains occur with the previous one in the plan rectangular shape of the slider by cornering the same to the center of curvature facing Edges produce considerable inhibitions and noises.

According to the invention, obstacles and the resulting noises, slider breaks and the resulting time-consuming replacement of the curtain slider are to be avoided in that one leg end of the hook or both leg ends of the U-shaped eyelet around a curtain glider above the end wood side of the support flanges of the curtain rail made with resin-free oil

Contacting sliding surfaces are mounted in the slider arranged bearing journals.

When using normal slide rails with an I-shaped cross-section in a vertical arrangement of the With the I-bar, the slider is designed as an eyelet that can be folded down on one side or on more than one side. Here is According to the invention, the one eyelet is mounted in a lateral journal of the slider. The other Eyelet is in turn designed as a sliding eyelet for the purpose of hanging and unhooking provided with an elongated bearing slot that extends below into one opposite the bearing pin and The opening opens into this eyelet leg, which is provided with the longitudinal slot, can now be used when threading the The curtain can be hooked in and unhooked.

Another feature of the invention, in which the slider as an inner slider on the flanges of two parallel U-irons with flanges facing each other are two opposing slides Slider halves, one below the other and at a distance of a curtain hook thickness by a bearing pin for the curtain hook serving pegs are connected to one unit.

The lateral hook or eye pins used here are according to a further embodiment of the invention when consisting of sliders and fixed hooks Curtain supports in a known manner with their fastening end in a pilot hole of the Glued and cemented gliders.

Fig. 10 shows the glider in plan, mainly on curved slide rails. .

The subject of the invention is a curtain support made of a hygroscopic material of the capillaries Structure, in particular made of hardwood slider 1 and a mounted in this, in the direction of movement the curtain swingable, suitably metallic curtain hooks 2 or a curtain eye 3 exists. ... -

According to the invention, the sliding surfaces are 4 cross-sections to the direction of the capillaries of the hygroscopic material. So the sliding surfaces 4 are the Wooden sliders, so-called end-grain or head wood surfaces. The sliders 4 are known instead of using paraffin Way with a resin-free oil, e.g. B. with spindle oil or bearing or machine oil, soaked. Curtain hooks 2 or eyelet 3 are above the sliding surfaces 4 in holes 5 of the slider -1 or on mounted metallic pin 6, the attachment end inserted into pre-drilled holes 7 and with are glued or cemented to the slider 1. Here, the fastening ends of the pins 6 are barbed 8 provided.

When using metal profile rails with an I-shaped cross-section, the curtain eyelet is either mounted according to the left or right section half of Fig. 2 or Fig. 4.

According to the invention, the curtain eyelet 3, as shown in Figs. 4 and 5, is arranged so that it can be hung in and out. For this purpose, the bearing hole of one or both free curtain eye legs is an elongated hole 9 formed, which has a recess 10 at the bottom, the width of which is greater than the diameter of the outer journal collar 11 is. The opposite free leg of the curtain eyelet 3 can either Storage hole alone, a simple longitudinal or sliding slot or an entry and exit that is expanded at the bottom Have a release slot.

According to the exemplary embodiment Figs. 6 and 7, according to which the slider of the curtain support slides primarily on the narrow edge of the flange of the slide rail with an I-shaped cross-section, which is horizontally arranged with the web, the curtain hook 2 is mounted on the slider 1 in place of the curtain eyelet 3. The free hook shank forms with the slider 1 a narrow threading gap 12 for the curtain cord. This free leg can also be provided with a suspension slot according to FIG. 5 for the bearing pin 6 with a bearing pin collar 11 in the slider 1.

In the exemplary embodiment according to FIGS. 8 and 9, the slider 1 designed as an inner slider is in two equal halves divided, but the distance of the thickness of the curtain hook 2 by the community borrowed also serving as bearing pin 6 connecting pins are firmly connected so that they form a unit. Two underside cuboid lugs 15 of the slider 1 take hold of by the two slide rails 13 formed guide slot 14 so far that the upper end 16 of the free hook leg is still encompassed by the tab-shaped projections 15 of the slider 1, so that it is thrown out of the moving curtain from the curtain hook 2 is not possible. Threading the curtain cord happens in the extended position of the curtain hook 2 in Fig. 9.

In the embodiment according to Fig. 10, the slider 1 is primarily for use on curved Sliding rails in the ground plan conical, spherical or pearl-shaped instead of the previous rectangular rounded shape, so that the sliders touch each other only at a point directed towards the center of the arc.

As a result of the friction and the associated heating of the glider and as a result of the particularly the selected resin-free impregnating agent, such as z. B. machine oil or bone oil, for example, easily finds its way to the sliding surfaces.
