Definitions

  • the invention relates to a locking device for a plurality of slats which are arranged together in a venetian blind device, a corresponding venetian blind device and a method for actuating the locking device for locking or unlocking the slats of such an external venetian blind device according to the invention.
  • venetian blinds for sun and heat protection outside in front of windows; these venetian blinds are also referred to as venetian blinds (with slats that can be pushed together) and such slatted venetian blinds or slatted blinds are the subject matter of the invention.
  • Such venetian blinds usually have ladder tapes for supporting, spacing and turning the slats and a lift tape for raising and lowering the slats.
  • Appropriate drive and power transmission elements can be accommodated in a head rail, which can be attached to the wall by means of brackets and brackets.
  • a lower rail forms the lower end of the plate pack.
  • the slats of an external venetian blind can be manually operated using a lift belt or roller chain, or they can be raised and lowered electrically using the aforementioned drive.
  • the EP 1 118 746 A2 describes a slatted blind, the slats of which are guided with their ends in lateral rails by means of a slat carrier.
  • the slats are individually removed from a slat pack arranged in an upper or lower area with the help of the slat carrier from below or above using the slat carrier and guided downwards or upwards.
  • the drive device disclosed there has a revolving conveying element with recesses for receiving the disk carriers. Due to the fact that the slat carriers are fixed in the conveying element, the slats lifted from the stack are held in their position when the blind is partially or fully extended and cannot be displaced. The conveying element is therefore burglar-resistant, since it is not possible to open the blind by force without destroying it.
  • the U.S. 2,205,156 A discloses a roller blind that is designed to be burglar-proof. It has lockable slats for this purpose.
  • the U.S. 5,282,514 A discloses a blind that also has lockable slats.
  • the further object of providing a burglar-resistant venetian blind that can be secured against the slats being pushed up is achieved by the venetian blind device with the features of independent claim 9 .
  • a method for actuating a locking device in order to be able to prevent the slats from being pushed up to prevent burglary is disclosed by the features of claim 11 .
  • a locking device which is designed to be arranged in a venetian blind device with a plurality of slats, each slat on both sides (slats usually have an elongated, rectangular shape and "both sides” here means terminally on the two short sides facing away from each other ) each has a slat holder parallel to a longitudinal axis of the slat with a sliding head and neck section, the invention provides that the locking device advantageously has a profile rail with an open long side and a plurality of recesses on one of the edges that delimit the open long side.
  • the profile rail can be transferred between an unlocked position and a locked position by a rotary movement about a longitudinal axis of the profile rail.
  • the neck section of each slat extends through the open longitudinal side and each slat is guided in the profile rail with the sliding head and can be moved along the profile rail.
  • the locked position is the neck portion of each slat arranged in one of the recesses and each slat is arranged with the sliding head in the profile rail in a position determined by the respective recess along the profile rail immovably with respect to the rail longitudinal axis.
  • Unmovable means here that the slat is simply temporarily locked against being pushed up or pulled out of the profile rail as long as the rail with the neck sections of the slat holder lying in the recesses grips the sliding heads in a blocking manner.
  • a simple device advantageously prevents the slats from being undesirably pushed apart or upwards (in relation to a window on which the external venetian blind will be arranged during use) and an intruder could be granted access to the window.
  • the locking device has an actuating element for triggering the rotational movement of the profile rail, which is preferably provided by an end section of the profile rail at a first end or which is formed by a first pin end piece which is non-rotatably connected to the profile rail at a first end of the profile rail, wherein the end section or the first pin end piece has a thread-like link groove which adjoins the open long side of the profile rail and which extends in a circumferential direction corresponding to the arrangement of the recesses on the profile rail and in which an actuating pin can be guided.
  • This extends laterally from a lower rail of the external venetian blind device and can be moved in a positively guided manner on the lower rail in a slat plane defined by the majority of the slats, in which the longitudinal axes of the slats lie, so that the actuating pin guided in the link groove controls the rotary movement of the first pin end piece and thus the Profile rail triggers.
  • blade holder parallel to a longitudinal axis of the blade refers herein to the orientation of the blade holder with respect to its neck portion, which defines a pivot axis for pivoting or turning movement of the respective blade and connects the sliding head to a holder portion on which the slat is attached.
  • the pivot axis can be identical to the longitudinal axis of the blade if the neck portion of the blade holder is aligned with the axis of symmetry, ie the central longitudinal axis, of the blade, so that the expression "blade holder parallel to a longitudinal axis of the blade” means “blade holder aligned with the longitudinal axis of the blade”. should include.
  • the spacing and the position of the recesses on the profile rail correspond to the spacing and the position of the slats in a fully extended state of the external venetian blind device.
  • a "fully extended” blind is understood here to mean that position of the blind in which the lower rail is at its lowest position, i. H. at a maximum distance from the head rail and the slats of the external venetian blind thus occupy a maximum area.
  • the length and inclination of the link groove is suitably matched to the depth and spacing of the recesses, taking into account the location of the bottom rail in relation to the slats.
  • the rotation can thus be performed by a predetermined angle in a range of, for example, approximately 40° to 90° (depending on the depth of the recesses, among other things).
  • the locking device can have a securing element for the profile rail in the locking position.
  • the neck section of the slat holder defines a pivot axis for turning the slats between an open position, in which the surfaces of the slats are positioned parallel to one another, and a shading position, in which the surfaces of the slats lie next to one another
  • the securing element is formed at least one predetermined blade holder on at least one predetermined blade.
  • the sliding head of this lamella holder designed as a securing element has a latching element which has a latching direction perpendicular to the surface of the lamella or to the surface of the lamella holder section.
  • the latching element is designed as a kind of locking bar for engaging in a latching recess which is present on the profile rail at a predetermined circumferential position which is selected in relation to a circumferential position of that recess which is assigned to the predetermined lamella in such a way that engagement of the latching element in the Recess is provided when the profile rail is in the locked position and the slat in the shading position.
  • the burglar resistance already provided by the locking device in the lock can be effectively reinforced by the security element, which prevents the profile rail from twisting into the unlocked position.
  • the formation of a blade holder as a securing element is structurally simple and does not require any additional drive or clutch components.
  • Securing is finally achieved by turning the slats into the shading position around the slat pivot axis, with the slat holders being rotated with the slats accordingly, so that the latching element on the sliding head of the predetermined slat holder in the shading position points in a radial direction of the profile rail perpendicular to the slat pivot axis and in can engage in the locking recess provided for this purpose on the profile rail.
  • the positioning of the locking recess required for engagement with the locking element can be predetermined with the position of the locking element on the pivoted sliding head based on the assignment to the recess in which the predetermined blade holder is accommodated.
  • the locking recess on the profile rail is preferably adapted to the width of the locking element in the circumferential direction, so that a rotary movement of the profile rail into the unlocked position is prevented.
  • the latching element can be designed as an immovable projection on the sliding head, with the latching recess being dimensioned larger than the length of the latching element in the longitudinal direction of the profile rail, so that the latching element can be moved into and out of the latching recess by pivoting the lamellae without the locking element touches the inner wall of the profile rail when the sliding head rotates.
  • the latching element is preferably designed as a spring-loaded latching element which can be transferred from a latching position against the force of a spring element into a transfer position in which the latching element has at least partially penetrated the sliding head.
  • the latching element can thus move back into the transfer position during the rotation of the sliding head when it comes into contact with the profile rail or the inner wall of the profile rail.
  • a locking head of the locking element can be rounded on the sides, especially in the pivoting or rotational direction, so that when the sliding head rotates in the profile rail, a smooth transition is achieved when the locking element makes contact with the inner wall of the profile rail, as a result of which increasing pressure is exerted on the locking element is exerted against the spring force until the latching element is pushed back into the transfer position. Due to the spring force, the latching element can automatically penetrate into the latching recess when there is no longer any contact with the inner wall.
  • unlocking takes place in that the detent element comes into contact with the profile rail with the rounded edges in the pivoting direction during the rotation of the sliding head with the profile rail, whereby the detent element is pressed against the spring force into the sliding head.
  • the corresponding rotation of the sliding head takes place, with the locking element returning to the locking position when the contact with the inner wall of the profile rail decreases or ceases.
  • the predetermined slat has on both sides a slat holder designed as a securing element with the latching element on the sliding head for engagement in a corresponding latching recess on the respective profile rail.
  • the predetermined slat can preferably be the uppermost slat of the plurality of slats arranged in the external venetian blind device, since the securing device is thus concealed behind an upper covering of the external venetian blind and manipulation of this slat is therefore the most difficult, if not impossible.
  • several slats can also be predetermined to have slat holders designed as securing elements, each of which can engage with a latching element in a corresponding latching recess on the respective profile rail.
  • the locking device can have a securing element for the profile rail in the locking position, which is formed by a second pin end piece which is non-rotatably connected to the profile rail at a second end of the profile rail and the one Has locking recess at a predetermined circumferential position.

  • the locking bolt is in the locking position, acted upon by a compression spring, and the locking device has an unlocking device with which the locking bolt can be moved into the retracted position against the spring force of the compression spring.
  • the profile rail has a polygonal or continuous, angular or rounded cross-sectional profile (square or polygonal, U-shaped or preferably circular arc-shaped C-profile), with the sliding head of the slat holder having a shape adapted to the selected cross-sectional profile is designed so that the sliding head present in the profile rail can be guided along the profile rail and can be rotated around the neck section. Additionally or alternatively, the sliding head is designed to engage behind the recess.

  • the profile rail is rotated into the locking position, taking the neck section of each slat in one of the recesses so that the sliding head engages behind the recess and each slat with the sliding head in the profile rail in a position determined by the respective recess along the profile rail is arranged immovably.
  • the method can include securing the locking position of the profile rail.
  • the locking position of the profile rail can preferably be secured by turning the slats from an open position, in which the surfaces of the slats are positioned parallel to one another, into a shading position, in which the surfaces of the slats lie next to one another.
