Abstract

The invention relates to a curtain glider (1) for hanging up and taking down a curtain (2) on and from a running rail (3). This curtain glider (1) has a gliding carriage (5) with, in the gliding direction, push-in projection (11) on one side and push-in recess (12) on the other side, so that the push-in projection (11) engages in the push-in recess (12) of a neighbouring curtain glider (1) when the curtain gliders (1) are pushed together. As a result, a stabilization of the curtain gliders (1) in the course of various movement sequences is achieved. In addition, the gliding carriage (5) has a centring frame (13) which bridges the gliding head (4) and possesses a centring recess (14) for the gliding head (4) pressed against it, the gliding head thereby always being aligned orthogonally to the guiding slot of the running rail (3), and consequently a detachment of the curtain glider (1) from the running rail (3) by itself being prevented. <IMAGE>

The invention relates to a curtain glider for hanging and removing a curtain from a running rail,

• with a T-shaped sliding head sliding in the running rail and a sliding carriage that can be moved underneath the running rail,
• the T-shaped sliding head is rotatably mounted in the sliding carriage against the action of a return spring by at least 90 °,
• the T-shaped sliding head has a laterally projecting control cam and
• the sliding carriage has guiding flanges projecting on both sides and a hanging bracket for the curtain on the bottom.

The older German patent application DE-A-42 38 455 is concerned with a device for hanging and removing a curtain from a running rail, the curtain having curtain gliders of the embodiment described in the introduction at predetermined intervals. The running rail is designed as a hollow profile with a guide slot running on its underside in the longitudinal direction of the rail with a predetermined slot width of the curtain gliders guided in the running rail. The head width of the T-shaped sliding head can be rotated by 90 ° chosen smaller and the head length larger than the slot width of the guide slot of the running rail. In the area of the guide slot of the running rail, a hanging magazine with an inlet channel or outlet channel for the curtain gliders can be placed against the underside of the running rail. The inlet channel has a control curve for the control cam and opposite guide curves for the guide flanges of the curtain gliders in such a way that the T-shaped sliding heads for exiting the running rail are rotated by 90 ° in the area of the control curve by means of the control cams and the sliding carriages are exited by means of their when the sliding heads exit Guide flanges are guided in the area of the guide curves. As a result, the curtain gliders can be transferred from the running rail into a hanging magazine and the curtain can be removed from the running rail at any position or can be hung into the running rail. The hanging magazine has a magazine rod adjoining the hanging head, which is set up to receive the pushed-together curtain gliders. This magazine rod is designed as a flexible washing magazine and can be folded together with the hanging head and the curtain to a size suitable for passing through washing machine openings while forming a wrap.

Otherwise, other types of curtain gliders are known with push-button-like plug connections in the sliding direction (cf. DE-A-22 16 323).

The invention has for its object to provide a curtain glider of the pretreated embodiment, the mutual stabilization of all curtain gliders guaranteed in the course of their different movements from the running rail via the hanging head into the magazine bar and vice versa, and also facilitates the hanging of curtains.

This object is achieved by the invention in a curtain glider of the generic type in that the sliding carriage has an insertion pin at its one carriage end and an insertion recess at its other carriage end for temporarily receiving the insertion pin of an adjacent sliding carriage when curtain gliders are pushed together, and in that the suspension bracket as downward V -shaped bracket for stretching the curtain suspended with two loops arranged at a predetermined distance from the hanging brackets when the curtain gliders are pulled apart. These measures of the invention have the result that a mutual stabilization of all curtain gliders is achieved when these curtain gliders are transferred from the running rail via the control curve and guide curves of the suspension head into the magazine rod of the suspension magazine and vice versa. Because with these movements, the curtain gliders are pushed close together and are now coupled via insertion pins and insertion recess to achieve a stabilizing effect. As a result, any tilting in the course of the transferring movement sequences is prevented with certainty, so that smoothness when removing and hanging a curtain is ensured. Because insertion pins and insertion recesses ensure stabilization All curtain gliders not only in the sliding direction, but also orthogonally. In addition, hanging the respective curtain is made considerably easier because the loops of the curtain hanging tape are each at the lowest point of the V-shaped hanging brackets when the curtain is pushed together and consequently pushed together, but when the curtain is pulled apart and consequently the curtain gliders are pulled apart, these loops on the V-legs of the Hanging brackets can slide up a predetermined amount up to the largest curtain expansion. The distance between the two loops with which the curtain is suspended from a hanger corresponds to the maximum spread of the V-legs of the hanger. As a result, the hanging length of the curtain is variable between a maximum and a minimum, so that an exact adjustment of the curtain length to the length of the guide rail is no longer necessary, but to the extent that there is scope between a completely pulled-apart and less-pulled-apart curtain. In this context, locks can be provided for the last curtain glider. End magnets, for example, can be used as locks if the last curtain glider is fitted with a magnetic plug. In addition, the curtain gliders are centered in the running direction when the curtain is pulled apart by the loops that slide up on both sides of the V-legs, especially since the inclination of the V-legs of the suspension brackets is selected under the self-locking mechanism and the friction is relatively low. The loops that slide up on the V-legs ensure a running direction uniform load on the curtain glider and prevent a running blocking inclination. - As a result, the curtain glider according to the invention ensures that the removal and hanging of a curtain is made considerably easier.

Further features essential to the invention are listed below. Thus, the invention teaches that the insertion pins are designed as multi-finger pins with an insertion wedge and possibly a locking member and the insertion recess as multi-finger receptacle with, if necessary, a locking recess for the locking and unlocking locking member. The multi-finger pin enables an almost elastic snap into the insertion recess, which increases the mutual stabilization of the curtain gliders. In addition, however, the curtain gliders can be pulled apart by loosening the smooth locking connection. According to a proposal of the invention with independent importance, it is provided that the sliding carriage has a T-shaped sliding head that slides in the slide rail in the sliding direction, and that the sliding head has a turnstile in the area of its control cam, e.g. B. a locking cam, which in a locking recess, for. B. engages a locking slot on the centering bracket, and that the axially movable sliding head with the rotary lock against spring action can be depressed from the locked position. These measures ensure that the T-shaped sliding head is properly fixed in the running rail, namely ensuring that the T-shaped sliding head or its T-beam always remains in a 90 ° position and consequently aligned transversely to the guide slot of the running rail. A independent adjustment of the sliding head when moving the curtain glider is prevented. As a result, accidental escape of the curtain glider from the running rail is also excluded. Only when the curtain glider is transferred from the running rail to the hanging magazine, is the T-shaped sliding head pressed down to release it from the running rail by means of the control cam and the rotary lock released, and rotated by 90 °. The turnstile or the locking cam forming the turnstile is preferably arranged on the control cam.

According to another embodiment of the invention, it is provided that the sliding carriage has a centering bracket bridging the T-shaped sliding head in the sliding direction and the underside of the centering bracket has a centering recess running transversely to the sliding direction, for example a centering groove, for the one aligned in the running rail and transverse to the sliding direction axially movable and pressed due to spring action sliding head or for its T-beam. These measures also ensure that the T-shaped sliding head is fixed correctly in the running rail, namely ensuring that the T-shaped sliding head or its T-beam always remains in a 90 ° position and consequently oriented transversely to the guide slot of the running rail, so that an independent adjustment of the sliding head is prevented when moving the curtain glider. Consequently, unintentional emergence of the curtain glider from the running rail is also excluded in this embodiment. In this context it is important that the T-shaped sliding head is suspended The curtain is pressed against the centering recess of the centering bracket by the curtain weight because the T-bar of the sliding head, which is movable in the axial direction of the T-web, rests on both sides of the guide slot in the running rail. As a result, the centering bracket is pulled against the T-shaped sliding head, as it were, due to the curtain attached to the suspension bracket. Because on both sides of the centering cantilevered guide flanges for the sliding block are formed, so that the centering bracket, the guide flanges and the sliding block with the suspension bracket can perform a relative movement to the T-shaped sliding head and vice versa. In addition, the T-shaped sliding head is pressed against the centering bracket by the action of the return spring, even when the curtain glider is not under load, and is consequently pressed into the centering recess because the return spring for the T-shaped sliding head is expediently adjustable both in terms of its torsional force and in terms of its compressive force. The sliding carriage preferably has a bore for a hollow pin which can be inserted therein for receiving the return spring, the T-shaped sliding head with its T-bar being guided axially movably below the control cam in the bore and optionally in the hollow pin with the return spring interposed. The hollow pin can be designed as a centering sleeve for the return spring and the T-shaped sliding head. But there is also the possibility that such a centering sleeve is used in the hollow pin. It is always ensured that the return spring the T-shaped sliding head after its release in a 90 ° position transverse to the direction of the curtain glider resets and consequently a perfect engagement in the running track is guaranteed. According to the invention, the suspension bracket is arranged in an inclined position with respect to the sliding direction on the underside of the sliding carriage, whereby an overlapping of the suspension bracket of adjacent and pushed curtain gliders is achieved. Such an overlapping of the suspension brackets, as it were, is necessary if the suspension brackets in the area of the upper ends of their V-legs are relatively wide or have a relatively large spread and even exceed the width of the curtain glider or its sliding carriage. This is the case, for example, if a relatively large curtain lift is required when pulling the curtain apart so that the "curtain head" or the upper curtain edge covers the curtain glider for aesthetic reasons and an unattractive gap between the running rail and the upper curtain edge is to be avoided, because to avoid self-locking, the angle of inclination of the V-legs is predetermined, and due to the loops slipping up on the V-legs, a sufficient curtain stroke can only be achieved if the suspension brackets are sufficiently wide or spread out. Furthermore, the suspension brackets in the area of the upper ends of the V-legs can have flattened angles of inclination, so that the loops get stuck there with mere strain relief, but ultimately slide back into the deepest part of the F-shaped suspension brackets when the curtain gliders are pushed together. In addition, the suspension bracket made of plastic can be snapped into and out of the slide carriage with its one bracket end.

While the return spring and possibly the centering sleeve are made of steel, the curtain glider is otherwise made of plastic.

In the figures, a curtain glider 1 for hanging and removing a curtain 2 from a running rail 3 is shown, the curtain 2 having curtain gliders 1 of this type at predetermined intervals and the running rail 3 as a hollow profile with a guide slot running in the longitudinal direction of the rail on its underside predetermined slot width is designed to pass through the curtain glider guided in the running rail. The locks that are customary in such a running rail - for example end magnets - are not shown, nor are corresponding magnetic plugs on the last curtain glider.

The curtain glider 1 has a T-shaped sliding head 4 sliding in the running rail 3 and a sliding carriage 5 which can be moved below the running rail 3. The T-shaped sliding head 4 is rotatably mounted in the sliding carriage 5 against the action of a return spring 6 by at least 90 °. The Head width B is smaller and the head length L is chosen larger than the slot width of the guide slot of the running rail. The T-shaped slide head 4 has a laterally projecting control cam 7 and the slide carriage 5 has guide flanges 8 projecting on both sides and a suspension bracket 9 on the underside. In the region of the guide slot of the running rail 3, a merely indicated hanging magazine 10 with an inlet channel or outlet channel for the curtain glider or slides can be placed against the underside of the running rail 3. The inlet channel has a control curve for the control cam 7 and opposing guide curves for the guide flanges 8 of the curtain glider 1 in such a way that the T-shaped sliding head 4 is rotated by 90 ° in the region of the control curve for exiting the running rail 3 by means of the control cam 7 and the Slide carriage 5 is guided in the area of the guide curves when the slide head 4 exits by means of the guide flanges 8. As a result, the curtain glider 1 can be transferred from the running rail 3 into the hanging magazine 10 and the curtain 2 can be removed from the running rail 3 at any point or hung into the running rail.

The sliding carriage 5 has an insertion pin 11 in the sliding direction at its one carriage end and an insertion recess 12 at its other carriage end for temporarily receiving the insertion pin 11 of an adjacent sliding carriage 5 when the curtain gliders 1 are pushed together. The suspension bracket 9 is designed as a downward V-shaped bracket for stretching the curtain 2 when the curtain gliders 1 are pulled apart. The sliding carriage 5 has a T-shaped sliding head 4 in the sliding direction bridging centering bracket 13 on. The centering bracket 13 has on its underside a centering recess 14 which runs transversely to the sliding direction for the sliding head 4 which is oriented in the running rail 3 transversely to the sliding direction and is axially movable and pressed as a result of the spring action against the centering recess 14 or for its T-beam. On both sides of the centering bracket 13 projecting guide flanges 8 for the sliding carriage 5 are formed. The return spring 6 for the T-shaped sliding head 4 is designed as an adjustable spring with regard to its torsional force and compressive force. Preferably, the sliding carriage 5 has a bore 15 for a hollow pin 16 which can be inserted therein for receiving the return spring 6, the T-shaped sliding head 4 with its T-bar with the interposition of the return spring 6 below the control cam 7 in the bore 15 and possibly in the Hollow pin 16 is guided axially movable.

According to a modified embodiment of the curtain glider 1, the insertion pin 11 is designed as a multi-finger pin with an insertion wedge 17 and possibly a locking element 18 and the insertion recess 12 as a multi-finger receptacle with a locking recess for the locking element 18 which can be engaged and disengaged. The sliding carriage 5 has a centering bracket which bridges in the sliding direction 3 the T-shaped sliding head 4 in the sliding direction without a centering recess, rather the sliding head 4 has a rotary lock 19 in the area of its control cam 7, namely a locking cam which fits into a locking recess 20, namely a locking slot engages on the centering bracket 13. The axially movable sliding head is with the turnstile 19 against spring action and consequently depressible against the action of the return spring 6 from the locked position. The turnstile 19 or the locking cam is arranged on the control cam 7. In this embodiment, a centering sleeve 21 is inserted for the return spring 6 in the hollow pin 16.

The suspension bracket 9 is arranged in an inclined position relative to the sliding direction on the underside of the sliding carriage 5, whereby an overlapping of the suspension bracket 9 adjacent and pushed together curtain glider 1 is achieved with a sufficiently large curtain or loop stroke, because the spreading of the V-legs of the suspension bracket 9 by the inclination does not interfere even if the suspension brackets 9 exceed the width of the sliding carriage 5 with their upper leg ends. The suspension bracket 9 has a flattened pitch angle α in the area of the upper ends of its V-legs. The suspension bracket 9, which is made of plastic, can be engaged and disengaged in the sliding carriage 5 with its one bracket end 22.

The return spring 6 and possibly the centering sleeve 21 are made of steel, while the curtain glider 1, in other words, the centering bracket 13, the T-shaped sliding head 4, the projecting control cam 7 and possibly the turnstile 21 and the guide flanges 8, the sliding carriage 5 and the suspension bracket 9 are made of plastic.
