Description

DESCRIPTION

The invention relates to a roller shutter with a curtain made of horizontal slats, which at their front edges in vertical guide rails can be guided between an upper end position and a lower end position.

Such shutters are in many forms generally known and are used in front of pensters, doors etc. attached to additionally close the window or door openings and a darkening of the corresponding To reach spaces. The slats of the roller shutters are usually made of plastic hollow profiles light weight, ease of use with simultaneous robustness and additional warmth and Ensure sound insulation.

Shutters are often partially lowered by the users during the day in order to close the rooms in front of them to protect against strong sunlight. Due to the flat curtain known shutters with only minor ones Known roller shutters are suitable for this purpose between the individual hanging slats only very imperfect, as it prevents direct sunlight from being too strong Darkening of the room in question. In general, therefore, must be too strong to prevent Sun exposure additional sun protection devices are provided, of which external ones Slat blinds are particularly suitable because they prevent the rooms concerned from heating up.

The simultaneous attachment of roller shutters and external sun protection devices, especially slat blinds with swiveling individual slats, is technically complex and often difficult or retrospective no longer possible. In any case, the installation of both roller shutters and venetian blinds is essential represent a considerable construction and cost effort.

There is therefore a need for external window or door protection devices that both as Roller shutters work effectively as well as slat blinds and are easy to install, operate and manufacture and the functions of a roller shutter, namely complete darkening, heat and sound insulation as well as burglar protection, and the functions of a sun protection device, namely the effective one Preventing direct sunlight with adjustable incidence of daylight, effectively combined.

The object of the invention is therefore to provide a roller shutter of the type mentioned above that is effective and simple can also be used as a sun protection device.

This object is achieved according to the invention in the roller shutter of the type mentioned in that the Slats are suspended on drawstrings and can be swiveled from a given upper slat and mot Turning belts are connected and carry at least one turning pin that at least one control jaw is arranged stationary and contains control sections which can be brought into engagement with the reversing pin and the reversible pen together with the pivotable ones

030065/0510

Swing out the slats before reaching a lower end position and after leaving the control jaw in Swivel back the curtain level.

The advantages of the invention are in particular that from a given upper lamella all further The slats underneath can be swiveled on drawstrings and reversible belts to form a swivel slat assembly are connected, the slats when lowering the curtain by interaction of the turning pin With the control cams of the control jaws, go over once into the swiveled-out position and then at the same time When lowering the curtain further, swivel it back into the curtain level. The slats so lie in the curtain level during the downward movement of the curtain. As soon as the curtain has a certain position reached, e.g. shortly before the lower end position, the reversible pin, and thus all of the reversible belts connected swiveling slats swiveled out of the curtain level. The inclination of the swiveled-out slats can be done indirectly via the control of the reversible pin by adjusting the height of the curtain fine-tune. If the reversible pin then leaves the control jaw, e.g. by briefly lifting the curtain and a subsequent lowering - or by means of an immediate lowering - so the reversible pin and so that all swiveling slats from the sun protection position back into the curtain level and then remain until to lower the curtain completely in this level.

A reversible pin is preferably located on the front side of the uppermost pivotable lamella, and it is for everyone Reversible pin, one control jaw in each of the two lateral guide rails for the simultaneous deflection of the two

030065/0510

the reversible pins provided. The attachment of two opposing reversing pins is particularly in the case of large widths of the slats, it is advisable to avoid a torsion of the pivotable slats and a resultant to prevent undesired inclination of the slats over the width of the curtain.

The lamellas are preferably on their upper longitudinal edge hinged to the drawstrings and particularly preferably have pivot pins in the extension of their upper longitudinal edge, which are rotatably attached to the drawstrings by means of hinge brackets and together with the drawstrings run in the guide gaps of the guide rails. The reversible belts are preferably made of elastic textile or plastic material and connect the swiveling slats at the lower free longitudinal edges. The reversible pencils have a predetermined distance from the pivot axis, to which they preferably run parallel and have a greater length than the guide pins.

The guide rails preferably have a cross-section that is as closed as possible, only towards the end face the lamellae is open and has a guide gap in which the guide pins are guided.

Spaced in front of the guide pin sits in the guide rails at a given height each a control jaw, which has a flow channel in the plane of the Has guide pin and a first outwardly and downwardly inclined control section and a second, contains substantially horizontal control section. Between the first control section and the second

030085/0510

The control section is the inlet opening for a return channel that slopes upwards with a lesser incline returns the flow channel. The first control section closes in a first position below the Effect of a bias the upper entrance of the flow channel and can be from the up through the Swivel the through-flow channel guided reversing pin into a second position in which the upper entrance of the Flow channel is free. The turning pin coming from above is in this Ausoildung of the control cam from first control section and then pivoted out of the curtain level by the second control section. From this sun protection position, the turning pin can then be moved by slightly lifting the curtain lead back through the return channel into the flow channel. The reversible pen - and all free longitudinal edges of the pivotable ones that are synchronously guided with the reversible pen Slats - is then back in the curtain level. Then the upward movement continue, the reversing pin then moves from the bottom against the first control section, swivels it

against the effect of the preload - into the second position and exits the flow channel upwards. Alternatively, the curtain can also be lowered again until the lowest lamella is on the window sill etc. and the curtain closes completely. The first control section is preferably a leaf spring formed, the lower end of which is hinged directly above the return channel, and the upper end of the freely towers over the upper entrance of the flow channel.

The advantages of this control curve are special in that the operation of the inventive

030065/0510

Roller shutter is exceptionally simple and is only possible through a single control element with which the curtain is moved up or down. An additional control element for switching over from roller shutter operation in sun protection mode is not required.

The slats are suspended with a space in between when the tension straps are taut. At the end of a lowering process First the bottom lamella is supported on the windowsill, etc., and then the one above it arranged slats on the slats below, which closes the gaps. Opposite longitudinal sides of adjacent slats are preferably with a groove profile and a corresponding one Formed spring profile, which interlock with mutual support of the slats and effectively lock the curtain. The groove profile preferably also has the lower end of the lamellae an external overlap edge that extends outside over the upper longitudinal edge of the lamella hanging underneath and the space in between, even with freely hanging ones Covering slats to the outside.

The drawstrings are preferably made of a resilient material, for example a spring steel band, and are together with the guide pins arranged in the guide gaps of the guide rails. As soon as the slats support each other in their lower end position, form the sections of the tension straps between adjacent ones Guide pin bulges or bulges and stretch each guide band in a wave shape between the parallel edges of each guide gap. As a result, the curtain is against horizontal shaking movements within the guide rails secured so that wind pressure etc. does not generate any movement noises.

Fig. 1 shows in a detail the guide and turning members on one end face of the curtain 2 of the invention Roller shutter. At the end faces of the curtain 2 each-a tension band 20 is arranged vertically, on which the slats 4 are suspended at a predetermined distance such that between adjacent slats a there is a predetermined gap which is covered by the lower overlapping edges 8 to the outside is that the overlap edges 8 rest on the outer surface of the next lower lamella 4. From one given upper lamella 4, all lamellas below are pivotable by means of the upper longitudinal edge lengthening guide pins 16 are pivotably articulated in hinge brackets 20. At the outer end of the guide pin 16, an angle lever 24, 26 is attached, the one leg 24 parallel to the end face of the lamellae 4, and the other leg of which runs parallel to the guide pin 16 and is designed as a pin 25. All pins 25 are articulated to a turning belt 28 by means of hinges 30. The top pin 25 of the angle lever 24 is extended outward parallel to the guide pin and is designed as a reversible pin 26. The slats 4 have a hollow profile, which is at the lower end as a groove profile 12, at the upper end as a tongue profile is formed with the upper longitudinal edge 6.

A wall of the guide rail in question engages between the front end 9 of the slats 4 and the angle levers 24, 25 a, covers the angle levers 24, 25 and the turning belt 28 and has a guide gap 52, in to which the hinge bracket 22 and the tension band 20 are guided, see also FIGS. 6-8.

Within the guide rail 50, a control jaw 40 is arranged in a stationary manner at a predetermined height and has it a control curve which is predetermined from control sections 44, 46, 48, 42 and which is generated with the reversing pin 26 cooperates. The two lateral guide rails carry each opposite at the same height a control jaw, and the upper swiveling lamella carries a turning pin at the front at the same height 26th

2 to 5 show the side view of a first embodiment of the two guide rails oppositely attached control jaws for different relative positions of the turning pin bearing upper swiveling lamella 4 shown-Each control jaw 40 has in the plane of the guide pins 16 of the curtain 2 has a flow channel 42 which is closed by a first, outwardly and downwardly inclined control portion 44. The first tax section 44 consists of a leaf spring, the lower end of which is hinged and the upper end of which the flow channel 42 freely surmounted and locked in a first position, the rest position, and in a second Releases position against the action of its own spring force in the event of an upward force. The control jaw 40 also includes a substantially horizontal second control section 46. Between the first Control section 44 and the second control section 46 begins a return channel 48, the upward into the Through channel 42 leads back.

When the turning pin 26 approaches the control jaw 40 from above, the turning pin 26 finally hits

030065/0510

on the first control section 44, see FIG. 2. If the guide pin 16 is then moved further down in the curtain level 1, the turning pin 26 slides on the control section 44 obliquely downwards and then horizontally the second control section 46 outwards. In doing so, the belonging! ^1st Slat a pivoting movement into the sun protection position of the roller shutter, see FIG. 3, which is transferred via the turning belts 28 to all the slats 4 below.

With a further downward movement of the guide pin 16, the reversing pin 26 remains essentially in a Rest position on the second control section 46, see FIG. 4, as a result of which the pivotable slats 4 move upwards put inclined.

In order to leave the sun protection position, Fig. 3, 4, the guide pin 16 must be moved upwards beyond the mouth of the return channel 48 until the reversible pin 26 runs through the return channel 48 back into the flow channel 42, cf. Fig. 5. The original roller shutter position is now reached again, the swiveling slats are in the curtain level 1 returned. Then the movement of the slats, i.e. the curtain, can be either continue up or down. In the event of an upward movement, the reversing pin 26 finally emerges the upper opening of the flow channel 42 and thereby presses the free upper end of the first control section 44 aside.

Fig. 6 shows a cross section through a lateral guide rail 50 with a plan view of the guide and Turning elements of the uppermost swiveling lamella. The lamella 4 is closed at the front by an end cap 9. At the front of the upper longitudinal edge of the guide pin 16 is attached, which by means of the hinge bracket 22 is attached to the tension band 20 and protrudes into the guide gap 52 of the guide rail 50. At the Guide pin 16 sits the angle lever 24 with the turning pin running parallel to the guide pin 16 26, which is articulated to the turning belt 28. On the inside of the opposite the gap 52 The guide rail 50 sits on the control jaw 4O, against which the reversing pin 26 runs. The guide rail 50 is sealed against the slats 4 by means of a rubber band 56.

Figures 7 and 8 show a cross section along the line A-B of Figure 6. In Figure 7 are the drawstrings stretched by the slats 4, the curtain has not yet reached its lower end position. The drawstrings 20 including those surrounding the guide pins 16 Hinge bracket 22 guided in the guide gap 52 of the guide rail 50 and consist of one resiliently flexible material, e.g. spring metal.

In Fig. 8 the curtain has reached its lower end position, the roller shutter is completely closed, the individual Slats 4 are supported with their longitudinal edges against each other, whereby the spaces between adjacent Slats have disappeared. This has increased the distance between adjacent guide pins 16 decreases, and the drawstring 20 forms within

of the guide gap 52 waves. The wave troughs in which the hinge brackets 22 sit are g.-gen an edge 54 of the guide gap 20, the wave maxima 21 press against the other edge 54 of the guide gap 52. The curtain is thereby clamped in the guide gap and against horizontal movements secured.

FIGS. 9 and 10 show the schematic cross section through several lamellae, which are the one shown in FIG Form the curtain. Fig. 9 shows the hanging in the hanging state, in which spaces 11 between Form adjacent slats 4, which are covered by overlapping edges 8 to the outside. The upper long edge of the individual slats has a tongue profile 10, the lower longitudinal edge a corresponding groove profile 12. Fig. 10 shows the cross section corresponding to FIG. 9 in the lower end position of the curtain, in which all Slats connect in a form-fitting manner, with tongue and groove profiles interlocking and locking the curtain. The curtain ends in a lowermost slat 3, which has no profile on its lower longitudinal edge.

Fig. 11 shows the cross section of a further embodiment of lamellae, which can also be used suitable for the roller shutter according to the invention. The lamellae are all designed as joint lamellae 4 'and have a narrow first lamellar part 4a fastened to the drawstrings and one on the first lamellar part A further second lamella part 4b pivotably attached by means of a hinge 5. The first slat part 4a and the second lamellar part 4b have an incline on the hinge in the area of the hinge 5

tapered outer surface portion. The front turning pins 26 are arranged on the second lamella part 4b of the uppermost pivotable lamella. All of the second lamellar parts 4b lying therebelow are connected with turning belts 28. When the second lamella parts 4b are pivoted out, the outer surface sections, which converge at an angle, approach one another and finally support one another. Each hinge lamella 4 'then has an angular cross section which has a relatively high flexural strength. The lower longitudinal edge of the ^{hinge lamella 4 1} in turn has a groove profile 12 with an overlapping edge 8, the upper longitudinal edge is designed as a corresponding tongue profile 10 to enable the adjacent lamellae to be locked when the shutter is completely closed.

Figs. 12 and 13 show a second embodiment the lateral guide and control elements of the roller shutter according to the invention. In the two guide rails 50, a control jaw 40 is arranged stationary at a predetermined height, which largely corresponds to the one shown in FIGS. 1 to 5 shown control jaws and contains control sections 44, 46, 48, 42, which with front turning pins 26 cooperate. The first control section 44 is as in the embodiment 1 to 5, from a leaf spring, the lower end of which is immediately above the Return channel 48 is articulated, and its upper end in a first position, which corresponds to the rest position, comes to rest over the upper entrance of the flow channel 42. The free upper end is against pivot your own spring action into a second position

030065/0510

bar / which releases the entrance of the flow channel 42.

In addition to the shape of the control jaw 40 shown in FIGS. 1 to 5, a control jaw is provided on the control jaw Swivel cam 60 is provided, which acts against the free upper end of the first control section 44. The swivel cam 60 pivots the free upper end of the first control section 44 in a first stable position its first position, in which the entrance of the passage 42 is closed. The swing cam 60 can be pivoted into a second stable position in which the free upper end of the first control section 44 passes into the second position in which the flow channel 42 is open at the top. At a given distance, preferably at a distance of a few larch widths, there is an adjusting cam below and above each turning pin 26 intended. During a downward movement, the lower adjusting cam 62 pivots the pivot cam 60 into the stable second position, so that the reversing pin 26 can run freely through the open passage 42 can and does not interact with the control sections 44, 46. With a subsequent upward movement pivots the upper adjusting cam 62, the pivot cam 60 in its first position, in which the first Control section 44 closes the flow channel 42 at the top. With further upward movement, the flow channel opens only when the reversible pin 26 moves past, which after the reversible pin has passed through from the first Control section 44 is closed again. If the curtain is then moved downwards again, then comes the reversing pin 26 into engagement with the control sections 44, 46, and slides along the after outwardly inclined first control section 44 downwards, whereby the with the turning pin by means of the turning
