Description

The invention relates to a closure element for attachment to a closure strip of a curtain, in particular to the closure strip of a roller shutter curtain according to the preamble of claim 1.

The function of a closure element with a stop element is in the DE 32 14 092 C2 described in detail. The terminating element is inserted axially into the open end of a terminating strip via an axial insertion section, the stop element coming to lie within the guide groove of the terminating strip, so that the stop element prevents the curtain from being drawn into the roller shutter box in the locked position.

The DE 20 2014 002 575 U1 shows another known termination element for attachment to a closure strip of a curtain, in which the insertion section is positively secured in the closure strip. The function of the stop element to limit the retraction of the curtain in the roller shutter box corresponds to that DE 32 14 092 C2 ,

The end strips of a curtain are designed in many different ways and mostly have different designs and profiles. Since a finishing element has to be inserted into the open end of a finishing strip, the finishing element must be adapted to the respective design of a finishing strip. This means that different end elements are required for different end strips.

The invention has for its object to provide a universal termination element for attachment to a closure strip of a curtain, which can be used in many ways.

The object is achieved in that the end element is composed of a first and a second basic component. The first basic component is designed as an end cap and has the insertion section which is inserted axially into the open end of the end strip. The end cap closes the open side of the end strip, the second base component having the base body for the stop element and the second base component being held in a form-fitting manner on the first base component. The arrangement is such that the first basic component and the second basic component are positively assembled with one another to form the terminating element according to the invention, which are advantageously separable from one another.

This inventive design of the end element allows the first basic component to be adapted to the design and / or the shape of the end strip without the second basic component having to be changed. Furthermore, the second basic component can be made available in different sizes, widths and lengths in order to be selected and assembled on site. With fewer components, there is great variability in the end element.

The basic components are designed in such a way that in the assembled position of the second basic component, the latter lies flush against an end face of the end cap.

The outer contour of the end cap corresponds to the cross-sectional profile of the end strip, so that a visually appealing closure of the axial end face of the end strip is guaranteed.

The insertion section is expediently provided on the end face of the end cap facing the end strip. On its end face facing away from the end strip, a connection profile is arranged, which is used for connection to the second basic component.

The connection profile provided on the first basic component extends at least over a partial height of the insertion section. The connecting profile advantageously extends over the entire height of the insertion section or is designed to be slightly higher.

In a special development of the invention, the connecting profile has an engagement web at one end, which projects beyond the end cap.

The second basic component is pushed onto the connecting profile for mounting on the first basic component, the second basic component being pushed onto the connecting profile in particular in the direction of the height of the insertion section.

For the positive connection, the connecting profile engages in a receiving groove of the second basic component, in particular without play. The receiving groove is expediently formed in a narrow side of the, in particular, cuboid base body. To limit the slide-on movement, the receiving groove is closed at one axial end.

A gap is expediently formed in the connecting profile, the gap advantageously serving to receive a locking element which is held in the second basic component.

In an advantageous development of the invention, it is provided that the base body of the second base component has a stabilizing web located at the front in the assembly direction. This stabilizing web is arranged in particular on a narrow side of the base body and is expediently provided for engaging in an engagement groove of a roller shutter rod carrying the end strip.

The other narrow side of the base body, which is parallel to the receiving groove for the connecting web, has a notch in which a pivot bearing the stop element is arranged.

The stop element has a first extent which is less than or equal to the thickness of the base body. A second extension measured in the same plane is greater than the thickness of the base body itself.

In an advantageous development of the invention, it is provided that the length of the end strip, together with the end elements arranged at its ends, has an overall length which corresponds to the length of the roller shutter rod carrying the end strip.

The termination element according to the invention 10 ( 12 . 13 ) consists of a first basic component according to the invention 1 ( 1 ) and a second basic component 2 ( 8th ).

The first basic component 1 ( 1 ) is as an end cap 3 educated. The outer contour 5 the end cap 3 corresponds to the cross-sectional profile 4 an end strip 14 which, in the exemplary embodiment shown, can be designed in particular as a design end strip.

The cross-sectional profile 4 in the exemplary embodiment shown, the end strip has the basic shape of a right-angled triangle, the base of which is curved. The curvature 15 ( 2 ) is designed such that the central section of the curvature 15 is closer to a right angle of the triangular basic shape than the end points 15 ' and 15 " the curvature 15 ,

The bottom bar 14 is preferably designed as a hollow profile made of plastic, aluminum, sheet metal or the like.

In the open end 6 the end bar 14 grips an insertion section 7 one on the end cap 3 is provided. The insertion section 7 is on the bottom bar 14 facing end face 13 the end cap 3 intended. The height extends H the insertion section 7 in the height direction of a high side 8th the end cap 3 , The height H corresponds to the clear height A of the open end 6 the end bar 14 , The dimensions are such that the insertion section 7 in a profile section 9 the end strip is held clamped. The length L the insertion section 7 is selected so that a secure connector between the first basic component 1 and the bottom bar 14 is achieved.

Is the insertion section 7 completely into the open end 6 inserted, closes the end cap 3 the open end 6 the end bar 14 , How 6 shows, the end cap lies 3 axially on the open end 6 the end bar 14 on. The end cap 3 has an outer contour 5 that the outer contour of the cross-sectional profile 4 the end bar 14 equivalent. The end cap is advantageous 3 the cross-sectional profile 4 the end bar 14 continued trouble-free. The contour 5 the end cap 3 forms an extension of the outer contour of the cross-sectional profile 4 the end bar 14 ,

For a secure hold of the end cap 3 on the bottom bar 14 to ensure wearing the end cap 3 on their the bottom bar 14 facing end face 13 an arch section 25 , which in the assembled state of the first basic component 1 the arch section 25 the end bar 14 engages behind. The arch section preferably extends 25 about 40% to 60%, especially 80% of those between the key points 15 ' and 15 " measured length of the curvature 15 ,

On her other, second face 23 the end cap 3 that are the bottom bar 14 is a connection profile 20 educated. The connection profile 20 extends towards the height H the insertion section 7 , The connection profile preferably extends 20 over a partial height of the insertion section 7 , especially over the entire height H the insertion section 7 ,

As can be seen from the representation in 4 is the connection profile 20 as a form-fitting connecting bridge 21 formed in the manner of a dovetail connection with a receiving groove 31 ( 10 ) of the second basic component 2 interacts. According to the top view 4 is the connecting bridge 21 designed in the shape of a hammerhead in cross-section and via a retaining bridge 22 on the end cap 3 established.

How 3 shows has the connection profile 20 a height V that are at least the height H the insertion section 7 corresponds; in 3 is the height V of the connection profile 20 slightly larger than the height H of the insertion section 7 , The height is preferred V of the connection profile 20 5% to 15%, in particular 8% to 10% larger than the height H the insertion section 7 ,

How 5 shows, the connection profile lies 20 within a slot 24 whose width B bigger than the thickness D ( 10 ) of the basic body 30 ( 10 ) of the second basic component. The width B is chosen so that the main body 30 with the receiving groove 31 narrow side 32 flush in the slot 24 is included. The narrow side is advantageous 32 flush with the bottom of the slot 24 on.

As the 3 and 5 show is the connection profile 20 at one axial end 26 with an intervention bar 27 extended. The surgery bridge 27 stands over the contour 5 the end cap 3 and engages - as will be discussed later - in an engagement groove 16 of an adjacent roller shutter bar 17 on ( 7 ).

The connection profile 20 also has a gap 28 on, which is about halfway up the connection profile 20 is trained. The function of the gap 28 will be discussed in the further description.

After inserting the insertion section 7 into the open end of the bottom bar 14 is the first basic component 1 firmly at the end of the end bar 14 held. The fixation on the end strip 14 can basically be achieved by friction. It may be advantageous for the first basic component 1 additionally mechanically on the end strip 14 to secure, e.g. B. by a locking screw, by gluing or the like.

After assembling the first basic component 1 according to 6 , the end bar 14 on a roller shutter rod 17 hooked in, what for a cross section, in particular L-shaped hook bar 18 the end bar 14 in one over the length RL ( 13 ) of the roller shutter rod 17 running engagement groove 16 is swung in. The pivoting movement for hanging the end strip 14 on a last roller shutter rod 17 of a roller shutter curtain is in 7 with the arrow 19 characterized.

The first basic component 1 will - how 8th shows - the second basic component 2 in the direction of assembly 11 postponed.

The second basic component 2 has a basic body 30 on how in 9 shown. The basic body 30 has a substantially cuboid shape with a thickness D that the width B the slot 24 on the first basic component 1 equivalent.

How 9 shows, is on the one, in the vertical direction of the basic component 30 extending narrow side 32 the receiving groove 31 arranged to the bottom 33 of the basic body 30 closed is. The receiving groove 31 is at its lower end 34 closed.

On the narrow side 32 opposite other narrow side 35 is a notch 36 provided in the one pivot 37 is provided. The pivot has an axis of rotation 38 that are perpendicular to the narrow side 35 lies.

On the bottom 33 opposite narrow side 39 points the main body 30 also a stabilizing bar 40 on. How 8th shows, the stabilization bar lies 40 in the direction of assembly 11 of the basic body 30 front.

How 8th shows, the pivot carries 37 a stop element 41 which is rotatable on the pivot 37 is stored. The stop element 41 is thus about the axis of rotation 38 of the pivot 37 pivotable.

The stop element 41 has a first extension E1 that are less than or about equal to the thickness D of the basic body 30 is. The stop element has the same level 41 a second extension E2 that are larger than the thickness D of the basic body 30 is. The stop element 41 has roughly the shape of a hammer head.

For the positive connection of the second basic component 2 with the first basic component 1 becomes the main body 30 of the second basic component 2 with its groove 31 on the connection profile 20 in the direction of assembly 11 postponed. The postponement movement is achieved by the connection profile 20 at the end 34 the receiving groove 31 limited. This ensures that the main body 30 of the second basic component 2 not about the contour 5 the end cap 3 survives. Only the stabilization bar 40 stands - like the intervention bridge 27 of the first basic component 1 - over the outer contour 5 the end cap 3 about. The surgery bridge 27 of the first basic component 1 and the stabilization bar 40 of the second basic component 2 complement each other to form a common web that engages in the engagement groove 16 of the adjacent roller shutter bar 17 intervenes like that 7 and 11 to 13 demonstrate.

Is the basic body 30 of the second basic component 2 completely on the connection profile 20 postponed, there is an opening 42 ( 8th ) in the basic body 30 congruent with the gap 28 in the connection profile 20 , In the opening 42 is a locking element 43 to insert ( 11 ), which provides positive locking of the second basic component 2 on the first basic component 1 guaranteed. The locking element 43 is conveniently a grub screw 44 whose threads are both in the opening 42 into the gap as well 28 digs in, thereby securing the body largely without play 30 on the first basic component 1 is achieved.

The connection profile 20 is from thighs 29 the receiving groove 31 engaging behind, thereby a form-fitting mounting of the second basic component 2 longitudinal 45 the end bar is achieved ( 12 ). Through the engaging locking element 43 is a form-fitting securing device transverse to the longitudinal direction 45 the end bar.

After screwing in the grub screw 44 to 11 assembly is complete; that from two basic components 1 and 2 composite finishing element 10 is functionally reliable at the open end of the end strip 14 assembled.

In the position of the stop element 41 to 12 , this is in a decommissioning position. In the locked position rotated by 90 ° 13 the stop element is in its operating position.

The length SL the end bar 14 forms together with the terminating elements arranged at their ends 10 a total length GL , the the Length RL the roller shutter rod 17 corresponds to on which the end strip 14 is attached ( 13 ). The ends of the roller shutter rod 17 as well as the stop element 41 lie together in a guide bar arranged in the window opening for longitudinal guidance of the roller shutter curtain.

A particular advantage of the two-part end element 10 is that the bottom bar 14 its length SL can be adapted to the installation requirements. The one with a cut in the bottom bar 14 resulting gap, can be caused by a second basic component 2 be compensated for, the second basic component 2 , especially the body 30 , one lengthways 45 the end bar 14 variable length G may have. Depending on the installation conditions, the end element can 10 from two different basic components 1 and 2 be put together.
