The invention relates to a panel curtain system, comprising a number of panels and a rail for guiding the panels, a control cord fastened endlessly to the panels, and at least one operating runner which is adapted for guiding in the rail and which is provided with means for attaching to at least one of the panels and with means for fastening the control cord.
Such a panel curtain system is known in practice. One or two known operating runners are mounted herein on one or both sides of the panel curtain, which is formed by one or more panels. The outer ends of the control cord are fastened to the operating runner(s). This generally takes place by means of a simple screw connection. An endless cord is in this way realized which is intended for manual operation of the panel curtain. In the relevant field the known operating runner is also referred to as cord carriage.
The invention has for its object to provide a panel curtain system of the type stated in the preamble with automated operation.
The panel curtain system according to the invention has for this purpose the feature that the panel curtain system comprises a motorized drive for the at least one control cord and that the operating runner comprises a tensioning element for tensioning the control cord in the situation of use of the panel curtain system.
In contrast to that in a manually operated panel curtain system, the control cord in an automated panel curtain system is wholly received in the rail and therefore no longer accessible from outside. By applying the operating runner according to the invention the control cord can also be tensioned in advantageous manner in the situation of use of the panel curtain system, i.e. after being mounted. This is of essential importance for a proper functioning of the motorized drive.
In a first preferred embodiment the tensioning element is adapted for receiving in one of the runner channels of the rail of the panel curtain system. The tensioning element is hereby accessible to a user via the longitudinal opening for the runners which is provided in the runner channels on the underside of the rail.
In an elegant preferred embodiment with improved convenience of use the tensioning element is adapted to receive one of the outer ends of the control cord in releasably clamping manner. The control cord can hereby be brought to the desired tension in simple manner.
In a practical preferred embodiment the operating runner is provided with a central part which is provided on one side with a guide element adapted for guiding in one of the runner channels of the rail, this guide element comprising the tensioning element.
An easy and reliable operation is achieved in a further development in which the tensioning element comprises a recess for receiving a first outer end of the control cord, this recess being adapted to clamp the control cord. According to the further development hereof, the recess is provided with a narrowed portion for further clamping of the control cord.
According to another preferred embodiment, an endless control cord can be realized in practical manner with one operating runner in that the guide element also comprises a further recess for receiving the other outer end of the control cord, this recess likewise being adapted to clamp the control cord.
Further advantageous embodiments of the panel curtain system according to the invention are described in further sub-claims.
The invention also relates to an operating runner as described as a component of a panel curtain system according to the invention.
The invention will now be described in more detail with reference to the figures.
In the shown preferred embodiment panel curtain system 1 is an automated panel curtain system which is provided with a motor accommodated in motor housing 6, which is mounted on rails 2 by means of a bracket 7.
Operating runner 10 is provided with means for attaching to at least one of the panels. In the shown preferred embodiment the operating runner is adapted for direct attachment to profile 4, and more particularly to one of the runners 24 mounted on profile 4. Attachment preferably takes place via a so-called snap connection, for instance a pin-hole connection, wherein pin 14 is provided on operating runner 10 and co-acts with a hole 34 on runner 24.
Rail 2 is provided with runner channels 20 and cord channels 21. Runner channels 20 and cord channels 21 lie adjacently of each other. Runner channels 20 are intended for guiding runners 24. In the shown preferred embodiment runners 24 are mounted on the upper side of profiles 4, and profiles 4 protrude outward from rail 2 through longitudinal openings 3. Cord channels 21 extend adjacently of the runner channels. Cord channels 21 are intended for guiding of control cord 5. The operating runner known in practice is received in the cord channels of the rail of the known panel curtain system. Cord channels 21 are not provided with longitudinal openings and are consequently only accessible from the side of the rail. In most situations this means that cord channels 21 are wholly inaccessible in the mounted position of the panel curtain system.
Operating runner 10 will be described in more detail with reference to
Operating runner 10 is adapted according to the invention for guiding in one of the runner channels 20 and in one of the cord channels 21. Operating runner 10 is provided with a central part 11 provided on either side with guide elements. Guide elements 12 and 13 are intended for guiding in one of the cord channels 21. Provided on the opposite side of central part 11 is an additional guide element 15 which is adapted for guiding in one of the runner channels 20. Guide element 15 also serves as tensioning element for control cord 5. All guide elements 12, 13, 15 are provided with recesses 22, 23, respectively 25 and 45 for receiving control cord 5. Recesses 22 and 23 are adapted for passage of the control cord, while recesses 25 and 45 are adapted for fastening outer ends 5-1 and 5-2 of the control cord.
Guide element 15 preferably takes a symmetrical form and recesses 25 and 45 are identical, as are narrowed portions 35 and 55. In this symmetrical embodiment the guide element can serve on both sides as tensioning element for the control cord.
The height of guide element 15 corresponds to the height of runner channel 20 and is chosen such that runner channel 20 guides guide element 15 fittingly. In similar manner the heights of guide elements 12 and 13 correspond to the height of cord channel 21 which guides guide elements 12 and 13 fittingly. Central part 11 has a smaller height. This creates the option of allowing control cord 5 to run through below central part 11 so as to thus realize an endless cord.
The invention is of course not limited to the described and shown preferred embodiments, but extends to any embodiment falling within the scope of protection as defined in the claims and seen in the light of the foregoing description and associated drawings.
