Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to a profile rail, at least two foldable door elements flexibly connected to each other, and a profile rail in which the door elements are pivotally connected. The present invention relates to a folding partition wall, in particular for showers, having a guide member displaceable in the longitudinal direction of the rail.

German Utility Model Registration No. 73 36 714 describes a folding partition wall with an upper horizontal profile rail, on which a plurality of guide members are displaceably arranged. The individual door elements are flexibly connected to these guide elements.

When the folding partition is closed, the individual door elements are aligned in the longitudinal direction of the profile rail. When opening this folding partition, a considerable amount of force is required to pivot the individual door elements in a horizontal row relative to each other. In the open state, known folding partition walls take up considerable space, with the individual door elements extending on both sides of the profile rail. This is particularly disadvantageous when used as a partition wall for a shower stall, since water still adhering to the door element will drip onto the outside of the shower tray. The end face of the door element located at the beginning of the connection always has a constant orientation with respect to the profile rail,
In the closed state, a par is installed that functions as a /Q lock. These nodules impede free passage when the collapsible partition is open.

Furthermore, German Utility Model Registration No. 7908685 describes a folding shower partition with three door elements. The central door element is connected on the outer side, ie on the side of the leading door element of the connection, with a relatively expensive guide slide. A third door element is pivotally connected to the other side of the central door element. In this example as well,
Considerable force is required to open the folding partition. The door element at the beginning of the connection has a plurality of fixedly arranged handles, which in the open state obstruct the passage of people.

The invention provides an improvement to a folding partition wall as mentioned at the outset, which requires only a small amount of construction effort and which, on the one hand, is easy to manufacture and install, and on the other hand, the handling of the folding partition wall is simple. , in particular the aim is to make it possible to open and close easily.

The improved folding partition wall has a secure and functionally adequate configuration with little bulk and weight. Furthermore, this folding partition requires less material and parts, has a longer service life and can be opened with less force. In the open state, the door element together with the handle occupies a minimum amount of space, so that the passage of people can be maximally free.

To achieve the above purpose, a nondle element is rotatably coupled by a hinge in the region of the side edge of the door element, and the nondle element is connected to the side line of the door element by a contact surface for opening the door element. the door element can be rotated about the axis of said hinge from the closed position by the nondle element, and the nondle element has a given position relative to the longitudinal axis of the profile rail in the closed and open states of the door element; It is proposed to be located at an angle.

The folding partition wall according to the invention has a simple construction, with a small number of parts ensuring, on the one hand, reliable guidance and fastening of the door element and, on the other hand, easy handling. With a rotatably connected handlebar,
The door element can be rotated very easily and with little force. The handle element is substantially approximately 9
It is arranged at an angle of 0u. The handle element projects from the outer surface of the door element and allows the user to grasp it without difficulty to open and close the folding partition.

The individual door elements also lie close together in the folded open state, with the handle element not interfering in any way. Although the door element requires minimal space in the open state, the handle element can be made considerably larger so that it can be easily grasped by the user. Preferably, the handle element extends over the entire height of the door element and is designed, in particular as a hollow profile, in order to save material and reduce weight.

In a particular embodiment, the hinge part connected to the door element has a cylindrical outer and/or inner surface, into which the guide element engages, in particular by a pivot lug.

Preferably, the hinge portion is part of the side profile of the door element. According to the invention, the door element and the associated handle element located laterally thereto can pivot around the same axis. The side profiles can be connected directly to each other by horizontal cross sections of the door element. According to the invention, the cylindrical hinge part is formed in one piece with the side profile, thereby improving the torsional stiffness of this part. The guide element can be easily manufactured from plastic, especially by injection molding, with the surface surrounding the projection or hinge part also being produced in one step with little effort. During installation, the guide element only needs to engage with the hinge part, and no particularly complicated and expensive installation operations are required.

In a particular embodiment, the longitudinal axis of the hinge portion is located at a distance from the bisecting plane of the door element. When the folding partition is closed, all door elements lie in the same vertical plane. Because the hinge part is arranged outside the bisected plane, the folding partition can be opened very easily and with little force by using the lever principle.

In an expedient configuration, the handle element abuts the leading edge of the flange of the side profile when the door element is closed, while when the door element is open said flange extends approximately from the handle element. They are rotated 90 degrees and separated. During opening, the door element is rotated by the handle element via the flange. That is, the rotation of the door element is caused by the handle element, but the handle element itself can be returned to its original position again, while the door element performs the required 90 degree rotation. It is advantageous if the handle element is associated with a stop q, preferably in the form of a pawl, which limits the rotation of the nondle element to a given narrow angular range, particularly preferably from 20 to 30[deg.]. Excessive pivoting is thus easily prevented, so that there is no risk of damaging other door elements during folding.

In one important embodiment, the upper guide element is connected to the lower guide element by a vertical connecting profile. The lower guide member also surrounds the hinge part like the upper guide member, or
Or it is engaged with the part by a protrusion. Due to the connecting profile, the two guide elements have a predetermined distance from each other in the vertical direction, the length of the hinge part being correspondingly set. The door element is relative to the guide member,
It is therefore also possible to provide a secure axial fixation to the upper and lower profile rails, without the need for expensive special fixing means between the door element and the individual guide elements. Installation can be carried out with very little effort as follows. That is, first, both the upper and lower guide members engage with the hinge portion,
The connecting profile is then fastened to the two guide elements, in particular by means of screws or the like.

The connecting section according to the invention has a vertically extending hollow chamber into which the projections of the guide members fit from above and from below. By means of fastening elements, in particular screws, a connection between the connecting profile and the projection or guide element is created particularly advantageously with little constructional effort.

In a particular embodiment, the upper and/or lower guide element has an axial support surface for the corresponding hinge part end face. The weight of the door element or elements is substantially
It is received by the support surface of the lower guide member. That is, according to the invention, the door element is not directly hung on the upper guide member as in the prior art, but is supported indirectly by the lower guide member, and is suspended on the axial support surface of the lower guide member. The clamping force exerted is extended via the connecting profile to the upper guide member.

In a particularly preferred embodiment, the cylindrical outer surface of the hinge part is surrounded over an angular range of more than 180[deg.] by a component having a cylindrical inner surface.

In a special embodiment, the component can also have a handle to facilitate handling of the folding partition. In other embodiments, this component can be part of the side profile of the door element or an integral part of the connecting profile of the guide element. Within the scope of the invention, the component and its cylindrical inner surface may extend over the entire vertical height of the door element or over a portion thereof. This component surrounds the hinge part with its cylindrical inner surface over an angular range of more than 18o0, so that the component and the hinge part are positively connected.

In order to guide the door element reliably and easily, the upper profile rail has a groove with two spaced apart guideways for two rollers, said two rollers being connected to the door element. are placed on both sides of the regular bisector of . In order to facilitate the opening of the door element, in a special embodiment the groove provided in the lower profile rail for the lower guide member is located in front of said bisected plane as seen from the opener, while the hinge The parts are located at regular intervals behind the regular bisector. An optimal force distribution is achieved during opening and closing, and stagnation and heavy movement of the door elements are reliably avoided.

In a particular embodiment, the connecting profile has a longitudinal groove extending in the longitudinal direction, in which groove the magnet S)IJ is arranged. According to the invention, a further magnetic strip or a magnetically attracted fastening element is arranged opposite the magnetic strip, said fastening element being fixed to the vertical profile frame of the folding partition. There is.

The present invention will be described in detail below based on specific examples shown in the accompanying drawings.

FIG. 1 shows a front view, partially in section, of a folding partition wall (frame structure consisting of upper and lower profile rails 2.4 and two vertical profile frames 6). Two door elements 8.10 are arranged within the frame structure, which elements 8.10 are connected to each other by a hinge belt in the middle. The door elements 8 , 10 each have an upper guide element 14 and a lower guide element 16 at the corner opposite the vertical profile frame 6 , these guide elements 14 , 16 being separated by a connecting profile 18 . connected to each other. In the region of the center line 19 of the folding partition wall, two door elements 8.10 are formed substantially equally;
are rotatably connected to each other. The joint section 18 has a hollow chamber 2o inside, and the guide member 14 is inserted into the hollow chamber 20.
, 16 are engaged by the projections 22. A fixed connection is achieved by means of the fastening element 24, which in this example is designed as a screw. Door element 8.1o has profile 25.26
It includes a frame structure constituted by, and a transparent glass etc. is installed in the frame structure by a normal method. The profiles 25, 26 are usually connected to each other by screws 27. The vertical side profile 26 has a hinge portion 28 having a cylindrical inner surface 30 and a cylindrical outer surface 32. A pivot lug 36 of each of the two guide elements 14.16 is inserted into an inner hollow 34 of the hinge part 28. Cylindrical inner surface 3 of hinge portion 28
0 surround a corresponding pivot projection 36 at each end of hinge portion 28 . The door element IO can thus pivot about the vertical longitudinal axis 38 of the hinge portion 28.

The hinge part 28 is connected by means of axial end faces 40, 42 to the guide elements 14, 16 as well as the cylindrical component 48 of the handle element.
0 is in contact with the support surface 44,46.

The upper guide element 15 of the door element 8 is indicated by a dash-dotted line.
When the two door elements 8.10 are fully folded, the 2
In order to prevent the guide elements 14.15 from closing automatically due to a collision of the two guide elements 14.15, the guide elements 14.15 have, according to the invention, a locking device, which in this example is configured as a snap mechanism. A hook 47 is provided on the guide member 14, and the guide member 15 has an opening 4 at a position corresponding to the hook 47.
It has 9. When the door elements 8,1O are folded, the hooks 47 reach the openings 49 and lock there in the corresponding rear cutouts, and the two door elements 8.1o remain open. The door elements 8, 10 can be displaced as far as the left-hand or right-hand vertical profile frame 6, as required.

The cross-sectional view in FIG. 2 shows the side profile 26 which is formed as a profile frame integral with the hinge part 28.

The hinge portion 28 is connected to the cylindrical component 4 of the handle element 5o.

The component 48 includes a pawl 51 located opposite the overhang 53 of the connecting section 18 . It is clear that the rotation of the handle element 5° is limited to a predetermined narrow angular range of the order of 20 to 30 degrees. The hollow space 20 of the connecting profile 18 is clearly visible. Longitudinal groove 52 of connecting profile 18
A magnetic strip 54 is inserted therein and cooperates with another magnetic strip 56 . A magnetic strip 56 or a magnetically attracted fastening member is fixed on a sealing bar 58, which itself is connected to the vertical profile frame 6 by a snap connection. The longitudinal axis 38 of the hinge portion 28 has a predetermined distance 62 from the plane 6o that bisects the front and back of the door element 100.

In the position shown, the handle element 50 rests with its contact surface 29 on the front edge 55 of the overhang of the side section 26 and has an angle 61 with respect to the longitudinal axis 59, preferably 90'. In the position shown, the bisecting plane 60 corresponds to the longitudinal axis 5 of the upper and lower horizontal section rails.
parallel to 9. When the handle element 50 is rotated in the direction of arrow 66, the door element 10 is simultaneously rotated;
As a result, the weighing partition opens. Due to the lever principle in conjunction with the given spacing 62, the opening of the folding partition is considerably facilitated. The intermediate region of the two door elements 8, 10 moves in the direction of the arrow 68, so that both door elements can finally be folded.

A hinge belt 70 connects the two door elements to each other in the middle. Rotation shaft 7 of hinge belt 70
1 lies substantially in the same vertical plane as the outer surface 73 of the door element 8,100. According to the invention, therefore, the axis of rotation 71 is located on the side opposite the longitudinal axis 38 of the hinge part 28 with respect to the bisecting plane 60 . For this, door element 8
, IO becomes considerably easier to release. It may be pointed out that the door element 8 also has a correspondingly pivotably arranged handle element. A connecting part 74 between one free end 72 of the internal component 4!3 and the hinge part 2'8. The free angular range between is defined such that the door element 10 can be rotated by at least 90 degrees in the direction of the arrow 66 from its illustrated position. Strap I provided on the joint profile 18! 76 limits the angular range of rotation, thereby avoiding unacceptable collisions of the door element with other components, such as, for example, water supply equipment.

FIG. 3 shows a cross section of the folding partition wall of FIG. 1 along a line located below the line -■ and parallel to the iron wire. 2 pumps 75 are connected to the connecting section 18,
This glue hole 7'5 is fitted into the opening 77 of the connecting section 18. The hinge portion 75 surrounds the outer surface 32 of the hinge portion 2B.

If a force is applied in the direction of the arrow 79, an unacceptable bending of the connecting section 18 is prevented according to the invention by means of the two ramps 75. It may be noted that the folding partition wall, as a rule, has a height in the vertical direction of 1.50 to 2.00 m, and that the connecting profile 18 has a length corresponding to said height. Hinge part 2 as above
The clamp 75 in engagement with 8 significantly improves stability with very little effort. Therefore, the connecting section 1
8 can be manufactured to be extremely slim and to be as light as possible using a minimum of materials.

The sectional view in FIG. 4 shows the upper guide member 14, which is guided by its rows 278.80 in the guide groove 82 of the upper profile 2. The rows 278.80 are located on each side of the bisecting plane 60 of the door element IO. The longitudinal axes 3.8 extending through the pivot projections 36 of both the upper and lower guide members extend at a distance 62

The guide grooves 82 provided in the lower profile 4 for the rollers 84, 86 of the lower guide element 16 are arranged on the opposite side of the hinge part 28 with the longitudinal axis 38 with respect to the bisecting plane 6°. .゛In Fig. 5, the folding partition wall is connected to two door elements 8.
, IO is shown open. Both gutter elements are closely juxtaposed and the two handle abutments 50 are arranged rotated about the longitudinal axis 59 by an angle 61 of about 960 degrees. When the door element assumes the position shown here, the two mutually parallel handle elements 5o substantially overlap said door elements 8, l.

will be in the same direction. The handle element 5o therefore does not obstruct the free passage through the folding partition and can be very easily grasped by the user.
Further in accordance with the present invention, the distal end 88 of the component 48 abuts the inside of the connecting portion 74, thereby forcing parallel alignment as shown. More importantly, due to the relatively small angle of rotation brought about by the pawls 51 as well as the flange 53 of both handle elements 50, the door elements do not catch on each other or even otherwise when the door elements 8, 1O are opened. The reason is that the rotation of the door element is not obstructed due to this. Rather, the two handle elements 50 can slide along each other, again with said handle elements essentially being parallel to each other in the illustrated open position.
