Description

The present invention relates to a slat shop for a window or a door with an outer frame and one A plurality of between two vertical legs of the outer frame used, pivotable relative to the outer frame Slats, with support strips on the vertical legs, with existing on the face of the slats, preferred bearing journals centrally on lamella end pieces, which in corresponding stock recordings of the carrier strips are stored and with an actuator for Swiveling the slats.

Slat shutters for windows or doors usually exist from an outer frame with two vertical and two horizontal Legs that include an opening, which is mostly from slats pivoted or rotatable in the outer frame is filled out. The slats are stored in carrier strips, which on the vertical legs of the outer frame are arranged.

In known slat shutters, the slats are in their carrier strips pre-assembled, and the pre-assembled plate pack then inserted into the outer frame and fixed there. For this purpose, the fittings are, for example, U-shaped rails trained, in the middle leg holes available are used as bearings for the end faces of the slats bearing journals striving in their longitudinal axis direction.

This configuration has the disadvantage that the pre-assembled Lamella packs unstable, especially not torsionally rigid are, so that the insertion of the plate packs in the Outer frame is already difficult. Another disadvantage is that the preassembled plate packs after Insertion in the outer frame by means of screw connections, for example to be connected with this, and at least two cover strips to cover the U-profile rails have to. This means an additional operation as well an impairment of the external appearance of the finished assembled store.

From CH-A-619 506 a slat shop is known in which the slats used on both ends are supported by spring elements on the outer frame. Thereby is between the support strips and the slat ends Frictional resistance generated by the slats in any Stay fixed in the rotational position. The problem is that when using too strong springs, the adjustment of the Slats are connected with great effort and in use from too weak springs slats by side Moving unintentionally can emerge from the outer frame.

The invention is therefore based on the object of a slat shop for a window or a door specify which one a simpler, on mounting screws and cover strips dispensing with assembly enables and ensures that none Slats can accidentally come out of the outer frame. In addition, the external appearance of the finish is preferred assembled store improved and a play-free and smooth Actuation can be achieved.

This task is carried out in a slat loading of the aforementioned Kind by the characterizing features of the claim 1 solved.

This configuration makes it possible to individually insert the slats insert the outer frame by the first support bar against the force of the spring element as far from the second Carrier strip is moved away that a lamella between the two carrier strips can be used. By appropriate The slats used can also be tampered with removed from the store, for example, around to replace them. By using a preferred on the first support strip acting spring element are the Slats between the two support strips under tension held and thereby advantageously rattling noises switched off.

Due to the adjustability of the relative position of the second support bar the voltage of the Spring element can be regulated as desired. The actuator is preferably operable from the outside, so that the The tension of the spring element can be adjusted when the slat is inserted is. The dimensions of the outer frame, the slats and the fittings are coordinated so that the Slats with completely immersed in the corresponding groove Carrier strips can be used in this. By diving out the first beam will be due to the spring tension the slats clamped between the two carrier strips, the preload by dipping the second Support bar adjustable from the groove using the control element is.

The dimensions are also preferably matched to one another, that by dipping the second support bar The slats are released by immersing the first support bar is impossible. The slats are in the outer frame locked.

According to one embodiment of the invention, the actuating element for the slats in a support bar can be moved longitudinally guided and as a toothed drive rod, for example formed which with a on the outer circumference of the associated Bearing pin combs existing notch. Hereby becomes a simultaneous and uniform in a simple manner Adjustment of all slats ensured without additional To take up space.

According to a further embodiment of the invention, the carrier strips used in grooves in the vertical Legs of the outer frame are present and as one for U-shaped carrier strip open towards the bottom of the groove, the middle leg at least over the outer edges of the grooves survive minimally and against the end faces of the slats bump, with the end faces of the lamellae and the middle leg the U-shaped support bar preferably with inclined surfaces are provided, which a stop for the slats form.

This configuration makes a suitable, screw-free Storage of the beams in the outer frame causes these are only inserted into the grooves need, since the second end position of the support bars on the used slats is determined. Through the control element is a defined protrusion of the second support bar the associated groove causes and due to the butt joints between the second support bar and lamella and between The lamella and the first support strip also the protrusion of the first Carrier strip determined via their groove. By at least minimal supernatant and always maintained Butt joints is any unwanted look through prevents slat loading.

The spring elements are preferably between the side legs one of the carrier strips arranged and for example designed as a coil spring. Alternatively, the support bar even be designed with resilient sections, which are supported in the groove.

According to a further embodiment of the invention Control element between the side legs of the expedient another carrier bar between two end positions guided, is supported on the groove bottom and is with a worm gear present on its outer circumference form-fitting with the drive rod guided in this support bar coupled. As a result, this carrier strip is advantageously into the desired position via the connecting rod brought in the groove and thus relative to the other support bar.

The adjusting element preferably has an elongated shape with perpendicular to the middle leg of the second support bar Longitudinal axis, as well as two end sections circular in cross section of different diameters, the larger one Diameter the distance between the free ends of the two Side leg corresponds to the second support bar and the smaller diameter the free opening cross section in Middle leg of the second support strip existing passage opening, and a middle section, which is total has the smallest diameter, the transitions between the middle section and the end sections coiled in the same direction around the central longitudinal axis of the control element Edge surfaces are formed. This is advantageous a worm gear is formed, in which the Drive rod meshes so that when the actuator is rotated this and thus the second support bar relative to the control element be moved. By supporting the actuator at the bottom of the groove, the second carrier strip is made from Groove dug out. Due to the configuration described this function is implemented very simply and reliably. By turning the control element, the locking and Loosening of the slats can be effected.

The meshing section of the drive rod and are preferred the edge surfaces of the actuating element are inclined in the same direction trained, which further improves the function.

The adjusting element is advantageously over the recess accessible in the middle leg of the second support bar, see above that an adjustment is possible even with inserted slats is.

The bearing journal assigned to the first carrier is preferred provided with barbs, which the recesses in reach behind this carrier bar to prevent accidental To prevent triggering of a slat once inserted, as long as the slats are not yet locked.

The end pieces on the end faces of the slats, who prefer to carry the trunnions point to the Bearing journal opposite side a flat boundary surface on which can be placed on the front of the slats are. A is preferred for attachment to the slats Impact pin molded into the material of the end piece. The face of the lamellae is also preferred Provide lying flat side with centering lugs. Alternatively, the end pieces can have a rotating circumference Spread over the federal government. The end pieces are preferably made of Made of plastic and have on the support strips opposite sides with the existing on the carrier strips Sloping surfaces interacting, offset from one another Attacks on.

The shutter shown in Figure 1 has an outer frame 1 with vertical legs 2, 3, between which one A plurality of horizontally extending slats 4 are arranged is. The slats 4 are relative in support strips 5, 6 pivoted to the outer frame 1, which in grooves 7, 8 are inserted in the vertical legs 2, 3.

As can be seen in FIG. 2, the carrier strips 5, 6 are in the associated grooves 7, 8 in the longitudinal direction of the slats 4th slidably used, these carrier strips 5, 6 to respective groove bottom 9, 10 can be open. The slats 4 are on the end face, for example with end pieces 11, 12 provided on which struts in the longitudinal direction of the slats 13, 14 are present with which the slats 4 in corresponding bearing mounts 15, 16 in the middle legs 17, 18 of the U-shaped carrier strips 5, 6, for example can be used.

For example, between the two side legs 19, 20 the support bar 5 are at least two, here as a coil spring illustrated spring elements 21, which are on the one hand on the bottom 9 of the groove 7 and on the other hand on the middle leg Support 17 of the U-shaped support bar 5. The Spring elements 21 are designed so that the U-shaped Carrier strip 5 in the relaxed state of the spring elements 21 protrudes beyond the outer edge of the groove 7.

The also U-shaped support bar 6 has - as best can be seen in Figures 3 and 4 - two on their central thigh 18 attached side legs 22, 23, which free end 24 of a side leg 23 twice at right angles angled to the inside of the U-shaped support bar 6 and with one opposite from the middle leg 18 striving web 25 forms a guide.

A drive rod extending parallel to the side leg 23 27 is between the web 25 and the angled free end 24 of the side leg 23 inserted and engages behind these with two outer frets 28, 29. These are longitudinally displaceable drive rod 27 guided on the side leg 23 stands with its section 48 raised above the guide 24, 25 over and is with on the inside of the support bar 6th projecting side 51 of this section 48 equipped with teeth 30, which with a on the outer peripheral surface of the journal 14 comb existing notch 31 (cf. Figure 2). The bearing pin 14 is designed so long for this that he was deep enough between the side legs 22, 23 of the support bar 6 engages during the journal 13 on the opposite side of the lamella 4 on the other hand, is short and only between the lateral legs 19, 20 of its support bar 5 engage, that the middle leg 17 of the carrier bar 5 from the bearing pin 13 engages existing barbs 32 becomes.

Between the side legs 22, 23 of the carrier bar 6 there are at least two actuating elements 33 which, as in FIG 3 and 4 are formed. The control elements 33 have a substantially elongated shape with the longitudinal axis 34 perpendicular to the central leg 18 the support bar 6 runs. The elongated shape is with two circular end sections 35, 36 of different diameters. The bigger one So is angled at the distance between the diameter free end 24 of the side leg 23 and the opposite adjusted free end of the side leg 22 that itself a sliding guide for the corresponding end portion 35 of the Adjustment element 33 results.

The diameter of the second end section 36 is so at the free cross section of one in the middle leg 18 of the carrier strip 6 existing passage opening 37 adapted that itself also a sliding guide for the in this passage opening 37 diving end portion 36 results.

The sliding between the two side legs 22, 23 End section 35 of larger cross section is outward bounded by a flat surface 38 perpendicular to its circumference, which is a support surface opposite the groove bottom 10 forms, while the end portion 36 has a smaller cross-section is limited to the outside by a profile surface 39, through the mouth of one in the direction of the longitudinal axis 34 face inserted into the actuator 33 slot 40 is interrupted, the entire profile surface 39th centrally severed. The profile surface is to the side of the slot 40 39 with inclined surfaces 41 inclined towards the slot, 42 provided, which in the one shown in Figure 4, the Slats 4 locking end position of the actuator 33rd with inclined surfaces 43, 44 present on the carrier strip 6 complete flush, while the actuator 33 on the other with its support surface 38 over the free ends of the side legs 22, 23 survives. Otherwise, the profile surface runs 39 perpendicular to the longitudinal axis 34 of the actuating element 33.

In the other shown in FIG. 3, the slats 4 are released The end position of the control element 33 is on the one hand over the middle leg 18 of the support bar 6 over and on the other hand closes flush with the free ends of the side legs 22, 23 from. In this way it is immediately recognizable from the outside whether the slats 4 are already locked are. This simplifies assembly.

The adjusting element 33 has between the end sections 35, 36 a middle section 45, the cross section of which is smaller than that of the two end portions 35, 36 and three quarters corresponds to a circle, while the fourth quarter of the Cross-section corresponds to a square in which the circle is enclosed is.

The at the transition between the two end sections 35, 36 and the central surfaces 45 formed edge surfaces 46, 47 run in the same direction spirally around the central longitudinal axis 34 of the control element 33 and are each the closest Face 38, 39 of the actuating element 33 inclined, so that on the outer circumference of the actuator 33 Worm gear 52 is formed.

The protruding over the guide 24, 25 in the support bar 6 Section 48 of the drive rod 27 has two inclined Inclined surfaces 49, 50, the inclination of the inclination of the Edge surfaces 46, 47 of the control element 33 corresponds. With this section 48 is the drive rod 27 between the Edge surfaces 46, 47 of the actuating element 33 in a form-fitting manner coupled, the one facing the inside of the support bar 6 Surface 51 of section 48 on the outer surface 53 of the middle section 45 rests.

This configuration has the effect that the carrier strip 6 by rotating the adjusting element 33 relative to this between the two shown in Figures 3 and 4 Moves end positions, the peripheral portion being square Cross section of the central portion 45 of the actuator 33 with the opposite surface 51 of the drive rod 27 interacts as a stop, so that the rotation of the Actuating element 33 is limited to approximately 270 degrees.

For the slats 4 are the two end pieces 11 and 12 as shown in the figures 5 and 6, here in particular the end piece 11 is shown with the short bearing pin 13. The end pieces 11 and 12 have a flat base body 54, on the one hand, the bearing journal 13 or 14 strives centrally and the other one to the front of the slats 4 pointing flat flat side 60. By the Bearing pin 13 or 14 is a central drive pin 61 performed, which is preferably made of plastic End piece 11 or 12 is injected or pressed. The end pieces 11 and 12 have on the flat flat side 60 Centering lugs offset laterally to the drive-in pin 61 62 on which a correct orientation of the end pieces Ensure 11 or 12 relative to the slats 4.

Furthermore, on the pin side of the end pieces 11, 12 webs 63, 64 arranged offset from one another, which with the inclined surfaces 43, 44 of the respective carrier strips 5, 6 interact as a swivel stop, which the maximum closing of the slats 4 limited. As another The slats 4 can stop one another for the closed position be overlapping.

The slat shop according to the invention is assembled in that the slats provided with the end pieces 11, 12 4 one after the other between the vertical legs 2 and 3 of the outer frame 1 are used. For this first the two U-shaped support bars 5 and 6 with the spring elements 21 and the drive rod 27 and the Adjusting elements 33 in the grooves 7 and 8 of the vertical legs 2 and 3 used. The actuators 33 are by Twist adjusted so that they are flush with the one hand free ends of the side legs 22, 23 of the support bar 6 complete and on the other hand over the middle leg 18 survive the support bar 6. This allows the Immerse the support bar 6 in the groove 8 at most.

Now the slats 4 are toothed by their notch 31 long journal 14 in the recess 16 of the support bar 6 used where they with the teeth 30 of the drive rod 27 engage. As a result, the slats 4 already secured against pivoting relative to the outer frame 1. Now the carrier bar 5 against the force of Spring element 21 moved so far into the groove 7 that the Bearing pin 13 of the slat 4 in the recess 15 of its Carrier bar 5 is insertable. After releasing the carrier bar 5 this is from the spring element 21 in the direction of the Slat 4 moves so that this between the spring tension the two carrier strips 5 and 6 is clamped, wherein the journal 13 with its barbs 32 the middle leg 17 engages behind this support bar 5, so that a the slat 4 accidentally falls out when inserted the next slat is prevented.

When all the slats 4 are inserted in this way the adjusting elements 33 are rotated about their longitudinal axes 34 so far, until their inclined surfaces 41, 42 with the inclined surfaces 43, 44 of the support bar 6 finish flush. By the twisting of the adjusting elements 33 becomes that in the worm threads 26 meshing drive rod 27 and with it the support bar 6 moved out of the groove 8. This will make the with its end piece 12 on the middle leg 18 of the support bar 6 supporting slat 4 moved accordingly, so that the support bar 5, on which the slats 4 with their Support end pieces 11 on the other hand, in the groove 7 opposite the force of the spring element 21 are moved into it.

Due to the protrusion of the support bar 6 over the outer edge the groove 8 ensures that the slats 4 with their Journal 13 and 14 no longer independently from the recesses 15 and 16 of the carrier strips 5 and 6 can be triggered. The slats 4 are thereby secured and at the same time between the two support strips 5 and 6 by the spring element 21 clamped so that the slat 4 no longer in Moved in the longitudinal direction and therefore no rattling noises occur can. Due to the butt joint between slats 4 and carrier strips 5, 6 is also any undesired review prevented.
