Universal inner glider for hanging up curtains, drapes etc.

The invention relates to a universal internal slider for hanging of curtains, drapes, etc., consisting of a T-shaped head section, a neck section, a circular, disc-shaped Section and a lower hook or eye section, and from a locking device to prevent rotation of the slider in a rail with an inner channel.

According to an older proposal, there is an inner slider for hanging of curtains, drapes, etc. from a T-shaped head section, whose thickness is designed so that it is at any point in the Pührungsschlitz a curtain rail with The inner guide can be pushed in and can be anchored in the rail after a turn around its longitudinal axis of 90 °. bar below the T-shaped head section, a rectangular section or square is formed, which leads down to in a thinner portion of the neck of the slider passes over, so that the slider after insertion into the guide slot of a Curtain rail and after lifting the slider, can be rotated by the mentioned 90 ° and after lowering the slider the qua-

the shaped section in the area of the guide slot Curtain rail arrives, so that the slider is secured against rotation. The disadvantage of this inner slider is that it is sicfy cannot be used with all curtain rails, since the width of the Guide slot is very different from rail to rail. (German patent application P 24 01 686.2).

A known internal slider is made of a bolt whose neck · part forms the intermediate portion of two juxtaposed _(hooks The hook portion of this known internal slider loading;. Is two, with its upper end to close to the plane of the underside of the bolt zoom reaching! Individual hooks which are resiliently expandable outwards when the slider is inserted into the guide channel of a rail. The disadvantage of this known inner slider is that a relatively large amount of force is required when inserting the slider into a curtain rail.

ie that the glider must be pressed with a relatively large force against the underside of the curtain rail. In addition, this known inner slider cannot be removed from the curtain rail at any point ^; rail can be removed from this. This well-known inner slider cannot be placed at any point on a narrow | Insert Einzelsehiene because not enough space, in this case for the spreading apart of the lateral single hooked for ^encryption: Addition stands. (German Auslegeschrift 2 107 224).

The possibility of being able to remove an inner slider at any point on a curtain rail was not particularly attractive until not long ago, as the removal of a curtain from a curtain rail could be done much faster at the usual entry opening.

In the German patent application P 24 01 686.2, however, a Einfütningsvorrichtung for curtains, drapes, etc. is described, j

509841/0124

by which the possibility is created, a curtain, curtain, etc. at any point on the curtain rail very quickly take off and hang up again, so that through this introducer the usual insertion opening in the curtain rails fully * coming becomes superfluous.

The object on which the invention is based is to provide a universal internal slider for hanging up curtains, drapes, etc. of the type defined at the outset, which can be inserted into a curtain rail at any point and can be removed again, can be used with most conventional curtain rails with internal guides and in particular in connection with an insertion device according to the • German patent application P 24 01 686.2 can be used.

There is a basic prerequisite for this introducer mentioned in that the insertion movement of the individual sliders into the curtain rail is not opposed to any resistance as far as possible and that, moreover, the engagement of the slider in the curtain rail after a rotation of the slider of exactly 90 must be completed. In addition, the anti-rotation force with which the glider is secured against rotation in the curtain rail will not exceed a certain level and the locking process must finally also after a reverse rotation of be completed again exactly 90 ° around the longitudinal axis of the slider.

Based on a universal internal slider of the type defined at the beginning Art this object is achieved according to the invention in that in the area between the disk-shaped section and the head section, pointing in the direction of movement of the slider and inwardly rotatable leaf spring elements are formed, and that on. the outer, free ends of the leaf spring elements up to the Area of the head section of the slider protruding upwards locking fingers are arranged. j

^; The invention is based on the knowledge that a leaf spring! j can be bent with much less force than can be twisted in itself. In other words, it is much more difficult to twist a leaf spring in itself than it is to bend it in the usual way.

This results in the following mode of action:.

jj

If the universal inner slider according to the invention is attached to any j ! any point of a curtain rail inserted into this, so; butt the arranged at the free ends of the leaf spring elements

ten and upwardly protruding locking fingers on the underside of the. Curtain rail and they are thereby supported at these points. When the slider is pushed further into the slot in the curtain rail, the locking fingers become parallel to the neck section of the slider pressed down, however, the sheet-j spring elements give way so that the snap-in ! fingers are displaced downwards parallel to the neck section of the slider. During the subsequent rotation of the glider around its longitudinal axis by 90, however, keep the locking fingers, due to the "much greater resistance of the leaf springs : against a twist, its vertical position running parallel to the neck cut of the glider, until finally the I insert the upper ends of the locking fingers into the area of the guide slot reach the rail and then pushed up by the leaf spring elements. The glider is now in the relevant Rail secured against rotation. When the slider is rotated back around its longitudinal axis by 90 °, the leaf spring learns ; te exerted a relatively high torque by the locking fingers, j so that thereby the leaf spring elements twist in themselves until j finally the locking fingers obliquely out of the slot area of the i. Curtain rails are pulled out, but these do not maintain their inclined position J, but are directly in their vertical position

Move back position, reflecting the comparatively large twisting; due to the force of the leaf spring elements. So it becomes

ensures that the slider can be used at any point in a curtain rail with very little effort ; can, by a comparatively large force against rotation, : chert, however, after exceeding a certain torque or rotation angle can be removed comparatively very easily from the rail.

. There is a particularly expedient embodiment of the invention

ι in that the leaf spring elements essentially form an angle of 90 or less 90 ° with the neck section of the slider! close and run essentially in a straight line.

The invention can undergo further expedient that the leaf spring elements have a thickness mm 0.1 to ^0.35! and now have a width of 2.0 to 3. Within this range there are very favorable force relationships between the torsional force of the leaf spring elements and the bending force of the same.

^! A handicap-free movement of the gliders in a curtain rail

It is further ensured that the locking fingers have a circular cross-section and that their diameter corresponds to the width of the leaf spring elements. The play when rotating the glider around its longitudinal axis in a rail is kept to a minimum by the seAusung.

The realignment of the locking fingers after they have been pulled out of the guide rail of a rail is favored according to the invention in that the upper ends of the locking fingers are rounded off .

Finally, the slider according to the invention can also be used for extremely low rails in that the side arms of the T-shaped head section have an essentially circular cross-section. When a curtain is thrown, the

ter pivoted around the point of support within the rail, but with a circular design of the T-shaped head section a tilting iie ^ t-s head section within the Rail is avoided. "■

Further advantages and details of the invention emerge from the following description of exemplary embodiments below Reference to the drawing.

It shows:

Pig. 1 is a perspective view of a universal internal slider according to the invention;

Fig. 2 shows a further embodiment of the slider according to ι of the invention in part in a curtain rail inserted state; and

Fig. 3 shows a certain stage in the release of the slider in a curtain rail.

The universal inner slider shown in Figure 1 consists of • a T-shaped head section 2, the side arms of which have a circular cross-section. On the neck section 3 of the slider, at a certain distance from the T-shaped head section, leaf spring elements 7a, 7b protruding laterally in the direction of movement of the slider are formed bar-like cam 1. This Ncckenvorsprung 4 is used to rotate the Oleiters with the help of the insertion device according to the German patent application P 24 Oi 686.2 to insert the slider in the correct rotational position in the slot of a curtain rail. At a certain distance from the cam projection 4, a 3-disk-shaped section 5 is formed, on which the slider is guided in the mentioned insertion device. The hook section 9 of the slider consists of two side by side

th hook sections with threading noses 10a and 10b for fastening of the glider on a curtain tape. Entertains! of the hook portion 9, a material extension 11 is formed with small pointed projections 12 protruding from the side. Through the material extension 11 prevents the slider when being inserted into the mentioned insertion device upside down on the curtain tape comes to hang.

Figure 2 shows a further embodiment of the invention, of the embodiment according to Figure 1 differs in _s that the leaf spring elements 7a'und 7b 'de-energized slightly obliquely upward run, that is, an angle to the longitudinal axis of the slider smaller 90th Upon insertion of the _i slider in the slot of a curtain rail abut the first upwardly projecting latch fingers 8a ^1, 8b 'against the bottom side of the curtain rail and are supported thereby to the free ends from. With a comparatively very low pressure, the lateral leaf spring elements bend into the position shown, with the greatest bending moment occurring in the area 14 of the leaf spring elements, thereby ensuring a displacement of the locking fingers 8a ¹ , 8b ¹ parallel to the longitudinal axis of the slider. In the position shown, the leaf spring elements press the locking fingers with little force in the direction of the arrows F. As in the exemplary embodiment according to FIG. 1, the slider also has a T-shaped head section 2 'and a bar-shaped cam section 4'.

In Figure 3, a phase is illustrated when removing the slider at any point on the curtain rail. Upon rotation of the slider about its longitudinal axis in the direction of Pfeiffer-t les A 7B is a ratio \ moderately large torque is applied to the leaf spring elements 7a, exercised, whereby the latching fingers 8a, \ 8b assume the illustrated inclined position. With a further rotation of the slider, the ends of the locking fingers finally slip out of the guide slot of the relevant rail 13,

however, return immediately to that illustrated in FIG Position back because the back torque of the leaf spring elements 7a, 7b is much greater than the bending moment, so that after

Exceeding a certain critical angle of rotation ** the further; Movement when removing the slider nurmehr a _comparable: the same as very low resistance against gent set.

It is obvious that a great safety against unintentional unlatching of The same \ ters is ensured by the described action and that even the glider after a slight twist again vonfeelbst returns to the desired j correct position in the curtain chine, j

A number of modifications and variations in the subject matter of the invention can be made without departing from the scope of the present invention ever- ^; but the described mode of action remains unchanged. ;

In addition, the slider according to the invention can also be uni use all over, as it has different slit; width is independent of curtain rails and is only

it needs to be established that the T-shaped head section has a ^!

has sufficient span. ;

All of the technical details recognizable in the description and shown in the drawing I are essential for the invention i significant.
