Description

FIELD OF THE INVENTION

The invention relates to a sliding element according to the preamble of claim 1 and a curtain or tarpaulin holder according to the preamble of claim 11.

STATE OF THE ART

Such sliding elements, also known as curtain rolls, are mainly used in the area of panel curtains, sliding curtains or tarpaulins made of different materials in connection with rails. The difficulty in using known sliding elements, e.g. Curtain rolls or double rolls is that when opening the curtain system, the first or outermost sliding element canted, whereby a smooth opening of the curtain is no longer possible.

For example, the DE 12 02 947 B a roller shutter for curtains, which has rollers, a spacer disposed between the rollers and a connection member for a spring clip or a curtain hook.

The DE 2 216 323 A1 However, discloses a rolling or Gleitaufhänger of plastic curtains with a body, wherein the main body is plugged together by a push-button type connector with the main body of an adjacent rolling or Gleitaufhängers.

TASK

The object of the present invention is to eliminate this drawback and to provide a sliding member in which canting of the sliding member, particularly the outermost sliding member, with respect to the guide rail can be reliably prevented. The opening of the curtain or the (tarpaulin) tarpaulin should be smooth. The construction of such a sliding element should be simple and inexpensive. The retrofitting of existing mounting systems should also be possible.

PRESENTATION OF THE INVENTION

This object is achieved with a sliding element, in particular a curtain roller, for slidably supporting a curtain or tarpaulin in or on a guide rail, comprising: a sliding portion for supporting the sliding element in or on a guide rail and a fixing portion for fixing a curtain or tarpaulin to the same Sliding element, wherein the sliding element has a laterally projecting spacer for on-distance holding the attachment portion and / or the
Sliding portion of the sliding member relative to an adjacent sliding member comprises achieved in that the spacer has a, preferably slot-shaped, receptacle for an adjacent sliding element in its end region.

The spacer prevents the tilting or tilting of the relevant sliding element when opening the curtain - so when sliding the sliding elements. With the spacer according to the invention, the sliding member is supported on the adjacent sliding element. The sliding element therefore retains an optimum position or orientation for the sliding operation. The spacer can therefore also be referred to as a support element. For this purpose, the spacer on a stop or support surface, which comes with the opening of the curtain or the tarpaulin with the adjacent slider in contact. On-distance holding the attachment portion means that a minimum distance between the attachment portion of the sliding member and the adjacent sliding member is ensured by the spacer. The spacer may be disposed on the attachment portion itself or above. The specified by the spacer (minimum) distance implies that tilting and thus tilting of the sliding element in the guide rail is limited or completely prevented.

The sliding portion forms the upper part of the sliding member, while the fixing portion forms the lower part of the sliding member. By the spacer is reliably prevented that the lower part of the slider is pivoted due to the curtain (or tarpaulin) transmitted forces (in the opening direction of the curtain). Rather, these forces are introduced via the spacer in the adjacent slider.

According to the invention, the spacer has in its end region a preferably slot-shaped receptacle for an adjacent sliding element. In this embodiment, the spacer can stabilize the adjacent sliding element in the lateral direction, by the freedom of movement of the adjacent sliding element is additionally limited by the recording. Tilting is reliably prevented here in any direction. The spacer exerts a kind of guiding function with the receptacle, which comes into (preferably form-fitting) engagement with the adjacent sliding element.

The invention enables a smooth opening and is an easy-to-implement measure, which is also applicable to existing curtain systems. Especially is advantageous if the first, ie the outermost sliding element of a curtain system is formed according to the invention. Because usually the first sliding element is the cause of tilting or stiff opening. Tilting with the adjacent sliding element can be reliably prevented with the invention.

It is preferred, when the spacer is formed such that not only the fixing portion, but also the sliding portion of the sliding member is held by the spacer at a distance from the adjacent sliding member.

The invention is particularly suitable in connection with curtain rolls or curtain double rolls. The spacer prevents - in its function as a support - the tilting of the rollers when opening the curtain. For the smooth operation of the curtain when opening the stabilization of just the first two curtain rollers (dual role and first single role) is crucial.

The invention is applicable to curtain and tarpaulin systems of any kind. The terms curtain and tarpaulin are in this application to understand wide: These include in particular window curtains, room dividers, covers of any kind, especially tarpaulins, curtains PVC tarpaulins especially for carports, tents, barns, sheds, warehouses, stables, clubhouses, and the like ..

Preferably, the receptacle widens in the direction of the end of the spacer, preferably funnel-shaped or wedge-shaped. The engagement with the adjacent sliding element is facilitated in this way and made possible even when the adjacent sliding element is slightly inclined.

A preferred embodiment is characterized in that the sliding element has a base body on which the sliding section and the fastening section are formed or fastened and in that the spacer is fastened or formed below the sliding section, preferably in the area between the sliding section and the fastening section is. This arrangement of the spacer causes a particularly efficient solution in terms of ease. The position designation 'below' here - regardless of the actual orientation of the sliding element - to be understood that the sliding portion is considered as the upper part and the attachment portion as a lower part of the sliding member. The solution according to the invention is particularly suitable for sliding elements whose upper part, ie the sliding section, is wider (preferably at least twice as wide) than the lower part, ie the Attachment portion. Such sliding elements may preferably be T-shaped, the sliding section being formed by the horizontal bar and the fixing section by the vertical bar of the T-shape. The spacer may be integrally formed with the main body, or be attached thereto.

It is preferred if the attachment portion of the body is elongated and is substantially normal to the longitudinal extent of the sliding portion. The preferably likewise elongate spacer protrudes from the base body in a direction which is transverse, preferably substantially perpendicular to the longitudinal extension of the base body. In the application of the sliding element according to the invention, e.g. in a hanging curtain, the spacer may be oriented substantially horizontally.

A preferred embodiment is characterized in that the spacer extends transversely, preferably substantially perpendicularly, to the direction which points from the sliding section to the fastening section. This embodiment causes an optimal initiation of the forces exerted by the curtain during the opening operation of the sliding element according to the invention in the adjacent sliding element, whereby a tilting of both sliding elements is prevented.

Preferably, a guide direction is defined by the sliding portion. The guiding direction results e.g. by a corresponding guide structure having a 'preferred direction', or rollers defining a rolling direction.

Preferably, the spacer extends substantially parallel to the guide direction, resulting in a direct application of force via the spacer into the adjacent sliding element.

A preferred embodiment is characterized in that the spacer has in its end region a stop surface for an adjacent sliding element, viewed in the guide direction, the stop surface protrudes further than the end of the sliding portion or substantially equally protrudes as the end of the sliding portion (ie substantially at the same height as the end of the sliding section). In the first variant, the sliding section of the sliding element can also be kept at a distance from the adjacent sliding section. As a result, the sliding sections of the adjacent sliding elements do not touch each other and no negative influence on the sliding process can take place. In the second variant, it may come to a touch of the sliding sections, but is still a Prevents tilting, since their relative freedom of movement is predetermined or limited by the spacer.

Preferably, the sliding portion comprises at least one movably mounted rolling element, in particular a ball or a roller. This promotes ease of movement; In addition, particularly good results can be achieved in connection with the spacer.

A preferred embodiment is characterized in that the sliding portion comprises at least two movably mounted rolling elements, which are spaced apart in the guide direction. Such so-called. Double roles are mostly used as the outermost sliding elements, while the other sliding elements are designed simpler (as a single role).

Preferably, the spacer elongated shape, whereby a material and space-saving construction is created.

A preferred embodiment is characterized in that the spacer is plate-shaped, wherein preferably the plate plane is transversely, preferably substantially perpendicular, to the direction that faces from the sliding portion to the attachment portion. By such a measure it is achieved, in particular, that the adjacent sliding element is reliably supported and is not pushed past the spacer or 'jumps by'. In the application, the plate plane of the spacer may be oriented substantially horizontally.

A preferred embodiment is characterized in that the base body is plate-shaped, wherein preferably the plate plane of the spacer is transversely, preferably substantially perpendicular to the plane of the base body. This allows a simple construction, in particular a reliable attachment (e.g., welding) of the spacer to the body.

The goal is also achieved with a curtain or tarpaulin holder, comprising at least one guide rail (also called running rail) and a plurality of sliding elements, which are displaceably mounted in or on the guide rail in the guide direction and are connected to a curtain or a tarpaulin. At least one sliding element is designed according to the invention, wherein the spacer of the sliding element faces an adjacent sliding element.

A preferred embodiment is characterized in that the spacer extends outside the guide rail. A tilting of the spacer itself with the guide rail is thereby prevented from the outset.

Preferably, the spacer extends substantially parallel to the guide rail, whereby an optimal introduction of force into the adjacent sliding element comes about. A preferred embodiment is characterized in that the outermost sliding element is designed according to the invention.

A preferred embodiment is characterized in that the sliding portion of the outermost sliding element comprises at least two rolling elements movably mounted relative to the base body, which are spaced apart in the guiding direction.

A preferred embodiment is characterized in that the guide rail has a guide opening extending in the guide direction, through which guide opening at least the attachment section of the sliding elements protrudes from the guide rail and that the guide rail has a, preferably flat, slideway for the sliding section running on both sides of the guide opening the sliding elements, in particular for the roller elements having. If the sliding portion of the sliding element is moved on the sliding track and a portion of the sliding element projects through the guide opening, there is in principle an increased risk of tilting of the sliding element in the guide opening, which is preferably designed as a longitudinal slot. Therefore, a sliding element according to the invention is particularly well suited for use in the described guide rail, since the tilting of the sliding element in the direction of the slide tracks is prevented by means of the spacer provided with the receptacle.

The figures show a sliding element 1 according to the invention for displaceably supporting a curtain 2 or a tarpaulin in or on a guide rail 3 (FIG. Fig. 3 ). The sliding element 1 has a sliding portion 5 for supporting the sliding member 1 in or on a guide rail 3 and a fixing portion 7 for fixing a curtain 2 or a tarpaulin to the sliding member 1. In the illustrated embodiment, the attachment portion 7 includes apertures 8 to which a curtain / tarp is secured.

In addition, the sliding member 1 comprises a projecting in the lateral direction spacers 9. By the spacer 9 of the mounting portion 7 of the sliding member 1 relative to an adjacent sliding member 11 at a (minimum) distance is maintained. The spacer 9 is here designed such that also the sliding portion 5 is spaced from the adjacent sliding member 11.

In the figures, a second sliding member 11 is shown, which cooperates with the sliding element 1 according to the invention when opening the curtain 2. When the first sliding member 1 approaches the second sliding member 11, the abutment surface 14 formed in the end portion of the spacer 9 abuts against the second sliding member 11. Thereby, the fixing portion 7 of the first sliding member 1 is kept at a distance from the adjacent (second) sliding member 11 prevents tilting or tilting of the sliding element 1 in the guide rail 3, whereby a smooth opening of the curtain is ensured.

The sliding member 1 of the illustrated embodiment has a base body 4 on which the sliding portion 5 and the fixing portion 7 are formed (or fixed). The spacer 9 is fixed to the base 4 in the area between the sliding portion 5 and the fixing portion 7, e.g. welded. The spacer 9 may be formed integrally with the base body 4.

The spacer 9 extends transversely (here: substantially perpendicular) to the direction 13 which points from the sliding section 5 to the fastening section 7.

By the sliding portion 5, a guide direction 12 is defined. In the illustrated embodiment, this is done by two movably mounted rolling elements 6 (in particular balls or rollers), whose arrangement define the guide direction 12. The elongate spacer 9 extends substantially parallel to the guide direction 12.

As already mentioned, the spacer 9 has an abutment surface 14 for supporting on the adjacent sliding element 11 in its end region facing away from the main body 4. In an alternative embodiment, the abutment surface (also seen in the guide direction 12) may protrude substantially equidistant than the end of the sliding portion 5 (in other words substantially) at the same height as the end of the sliding section 5).

The spacer 9 has in its end region a preferably slot-shaped receptacle 16 for an adjacent sliding element 11 ( Fig. 2 ). The receptacle 16 widens in the direction of the end of the spacer 9, preferably funnel-shaped or wedge-shaped. The stop surface 14 is formed by the inner boundary of the receptacle 16.

As if from a synopsis of Fig. 1 and 2 it can be seen that the spacer 9 is plate-shaped. In this case, the plate plane of the spacer transversely (here: substantially perpendicular) to that direction 13, which faces from the sliding portion 5 to the attachment portion 7. Also, the main body 4 may be plate-shaped, wherein - as out Fig. 2 can be seen - the plate plane of the spacer 9 transversely (here: substantially perpendicular) to the plane of the base body 4 is.

Fig. 3 Finally, shows a curtain or tarpaulin holder 10 with a guide rail 3 and the therein (in the guide direction 12) slidably mounted sliding elements 1, 11. On its underside, the sliding elements are connected to a curtain 2. The spacer 9 of the sliding element 1 faces the adjacent sliding element 11. Fig. 3 shows a position in which the spacer 9 is in engagement with the adjacent sliding member 11. The curtain 2 already forms a curtain fold in the region between the sliding elements 1, 11. It can also be seen that the spacer 9 extends outside the guide rail 3 and substantially parallel to the guide rail 3.

The sliding element 1 according to the invention with the spacer 9 is the outermost sliding element of the curtain or tarpaulin holder 10. It can, as in Fig. 1 and 2 be formed represented. Of course, two or more sliding elements of the holding system 10 may be formed according to the invention with spacers.

The operation is explained in more detail below: When opening the curtain of the shaft of the adjacent sliding element 11 (here: the first single role) in the funnel-shaped release or recording 16 of the spacer 9 introduces, whereby the adjacent sliding member 11 is kept at a distance and not tilted.

The sliding element 1 according to the invention may be made (for example from a standard double or multiple roller) from a base 4 (e.g., in the form of a base plate) of a solid material, e.g. Metal and / or plastic, be formed with a plurality of holes. In the upper bores, the rolling elements 6 (e.g., ball bearings) can be mounted on the main body 4 two left and two right, respectively. The exemptions or holes 8 in the attachment portion 7 (lower part or shaft of the sliding member) are intended for attachment of the curtain (or tarpaulin) made of different materials.

Under the rolling elements 6, the spacer is welded or attached. This spacer (also called guide plate) has at the front to the next sliding member 11 a funnel-shaped slot opening 16 and exemption.

Fig. 4 shows the guide rail 3 and the slider 1 in the front view, wherein the receptacle 16 faces the viewer. In particular, the shape of the guide rail 3 can be seen: This has an open bending profile which is open on the underside, that is to say the side facing the curtain 2, by means of a guide opening 17. On both sides of the guide opening 17, the guide rail 3 forms a slide 18, on which the roller elements 6 can roll. This slideway 18 is formed by substantially normal to the guide direction 12 aligned, planar portions of the guide rail 3. The profile of the guide rail 3 is divided into an upper, designed as a U-section section, starting from which the profile tapers by means of two oblique sections towards each slide 18. The width of the slideway 18 substantially corresponds to the width of the roller element 6. As shown, the sliding portion 5 is arranged with the roller elements 6 within the guide rail 3, while a part of the base body 4 protrudes outwards, so that at least the fastening section 7 connected to the curtain 2 is arranged outside the guide rail 2.

Finally, it should be noted that the invention is applicable to all possible curtain and tarpaulin systems. These include in particular window curtains, room dividers, awnings, tarpaulins (especially for pools), and the like .. The invention is not limited to the described embodiments and the aspects highlighted therein. Rather, a large number of modifications is possible within the scope of the invention. which are within the scope of expert action. It is also possible, by combining the means and features mentioned to realize further embodiments, without departing from the scope of the invention.
