Abstract:
The end of a roller blind tube has an insert with a bearing arbor. The insert is frequently a plug that is pressed to fit closely in the end, and thereby it becomes difficult to remove. The diameter tolerances on roller blind tubes and inserts are such that the operator meets very variable forces in pressing it in. According to the invention there may be provided a choice of diameters by providing the insert with longitudinal ribs that cooperate either with the original inside surface of the roller blind tube, which is normal, or with longitudinal grooves having slightly increased radius.
Abstract:
Two neigbouring roller blinds on the same drive shaft may be adjusted with respect to each other by letting one end plug comprise an un-coupling device. This un-coupling device may advantageously be made by means of an unwrap spring that is actuated by means of a ring that surrounds one end plug.
Abstract:
Traditional fixing of raising cords on pleated blinds occurs by means of plastic flaps sewn in place that hold knots on the raising cords. Adjustment of tension in the raising cords is difficult, because it may be required to loosen the knot and re-tie it i a better location. According to the invention this is avoided in that a plastic clip has slits, in which the raising cords are pinched and locked after being wound 1½ turn around an interjacent tongue in the plane of the plastic clip.
Abstract:
The present invention relates to an adjustment element for local adjustment of the circumference of a blind roller for a roller blind, said blind roller having a first end (4), and a second end between which the blind is wound, a blind roller surface (7), and an axis of rotation extending axially in relation to said blind roller (1 ), said adjusting element (2) comprising an adjustment means (15) adapted to be mounted in proximity to one of said ends (4) and adapted to be displaced relatively to said blind roller surface (7). In accordance with the invention an adjustment member is configured to partly encircle the circumference of said blind roller and adapted to cooperate with said adjustment means in a way that said adjustment member upon activation of said adjustment means locally is displaced from said surface of said blind roller to thereby adjust said circumference.
Abstract:
Mounting brackets (1) that have to be fitted in an aligned state, e.g. to carry a roller blind in order that it is parallel to the edges of a niche, are provided with oblong holes according to prior art, in order that the placement may be adjusted in connection with tightening of the screws use. According to the invention a larger capacity for adjustment may be obtained, in that washers (5, 9) with an oblong hole (3) are used, and in that the washes are rotatably fitted in holes (7) in the brackets.

Abstract:
A roller blind tube with fabric wound around it is mounted in brackets that have spade-shaped elements (3) provided in the axis. These elements cooperate with oblong holes (2) in terminating plugs (1) in the roller blind tube. According to the invention the oblong holes (2) are opened by rotating excentrically built rings (8). Hereby the roller blind may be hung on the brackets, whereupon the rings (8) are closed again.

Abstract:
Known bottom rails fulfil the requirements stiffness and adjustability at the time of installation, but a noted inequality in the load on the individual raising cord cannot be corrected wihtout a complex dismantling of the bottom rail. According to the invention the bottom rail is suspended in clips (7) that on the one hand holds the lowermost slat (5) and the raising cords (4), on the other hand has means (10) so that the tightening of the raising cords may be adjusted individually.
