Definitions

  • the present invention relates to a fastening device, especially for fastening roller blinds to a fixed construction.
  • One end of the tube is provided with a plug having an essentially cylindrically pin extending axially from said one end of the tube.
  • Said pin is designed to fit into a fastening device to be fixed on e.g. the wall in a suitable position in relation to a window, and said pin located in its position in the fastening device is designed in a way which enables the pin and the tube to be freely rotational. This is usually accomplished by placing the pin in a hole in the fastening device.
  • said first pin is actuated by a spring so as to be able to be axially pushed into the plug.
  • the first hole serves as the site for mounting the device on a wall by using a screw or other suitable fastening means.
  • the groove serves as the recipient for the spade-shaped pin; and the second hole, if present, serves as the recipient for the other, essentially cylindrical pin. If no second hole is provided, the groove itself may serve as the recipient for the essentially cylindrical pin.
  • FIG. 1 shows a fastening device 1a having a front side 2 and a back side 3 (not shown) and a material thickness 4 there between.
  • the device 1a is provided with one groove 5 in the front side into the material, and is further provided with a first hole 6 penetrating the device from the bottom of the groove 5 into the material to the back side 3 (not shown) and a second hole 7 extends from the front side 2 into the groove 5.
  • the device 1a is provided with "third" holes 8.
  • the device Prior to performing this second operation one should however make sure that the device is oriented in a way so that the point of intersection of the groove that is to serve as recipient of the spade-shaped pin and the rim of the device (i.e. the site where the groove meets the rim of the device) does not point downward. This will ensure that the roller blind tube will not fall down as a consequence of the action of the gravitational force.
  • the fastening devices according to the present invention may be mounted in the window frame by suitable means, such as screws, pins and the like. If appropriate, the devices may even be glued to the window frame.
  • the window frame in which the fastening device according to the present invention is to be mounted may be made of various different materials, such as plywood or other types of wooden materials, bricks or concrete.
  • the exact way of mounting the fastening devices according to the present invention will accordingly depends on the material of the window frame. Accordingly, when the window frame is made of plywood or other wooden material, it will be appropriate to mount the fastening device by means of wood screws which are screwed directly into the wooden material. If on the other hand the material of the window frame is made of bricks, concrete or the like it will be appropriate to mount the fastening device by means of a screw in combination with some kind of an expandable member, such as a plug in a predrilled hole.
  • the fastening device is provided with three intersecting grooves. These grooves are in a yet more preferred embodiment arranged so as to form a mutual angle of 120 degrees.
  • the presence of three intersecting groves in a mutual angle of 120 degrees has the advantage that al least one of the three intersecting grooves always points upward (as opposed to downward), making the exact axial orientation of the device arbitrary.
  • Another advantage is that the three intersecting grooves in a mutual angle of 120 degrees themselves define the second hole in which the essentially cylindrical pin of the roller blind tube is to be fitted. In such an embodiment it is further preferred that the first hole and the second hole are essentially axially aligned.
  • Fig 2b shows a plan view of the device 1b of fig 2a.
  • the second hole is clearly seen as defined by the three intersecting grooves.
  • the first hole may extend all the way through the expansion member or only part of the way through the expansion member. It is however preferred that said hole extends at least a substantial way though said expansion member, such as more than 50%, preferably more than 60 % and more preferred more than 75 % of the axially dimension of the expansion member.
  • FIG. 4a and 4b An embodiment of such a device having a leg portion is shown in Fig. 4a and 4b.
  • Fig. 4a is a side view and fig 4b is a plan view showing a fastening which additionally is provided with a leg portion.
  • fig 4a and 4b show a fastening device 1d having a front side 2 and a back side 3.
  • the device 1d is provided with three grooves 5 in the front side into the material, and is further provided with a first hole 6 penetrating the device from the bottom of the groove 5 into the material to the back side 3 and a second hole as defined by the three intersecting grooves extends from the front side 2 into the grooves 5.
  • the device 1d on fig. 4a and 4b is provided with a leg portion 10 which is integral with and extending from the back side 3.
  • the leg portion is provided with flexible means 11 for detachably engaging a mounting bracket which is suitable for mounting to a fixed construction
  • the leg portion of such a fastening device may extend 5 mm to 90 mm, preferably 15 mm to 70 mm and most preferred 20 mm to 45 mm, and the bracket may overlap the leg portion by 5 mm to 50 mm, more preferred 10 mm to 35 mm.
  • the fastening device according to this embodiment can be further attached to the fixed construction by hammering one or more pins through the respective "third" hole or holes of the fastening device and into the fixed construction.
  • such pin or such pins will further serve as additional attachment means for the fastening device per se.
  • a process for manufacturing the fastening device is also provided.
  • the fastening device may be made of any suitable material, such as polymers, for example thermoplastic polymers, such as PP (polypropylene), PE (polyethylene), POM (polyoxymethylene), PVC (polyvinyl chloride), PBT (polybutadiene terepthalate), PS (polystyrene) or PC (polycarbonate); or fibre reinforced polymers; or light metals, such as aluminium.
  • polymers for example thermoplastic polymers, such as PP (polypropylene), PE (polyethylene), POM (polyoxymethylene), PVC (polyvinyl chloride), PBT (polybutadiene terepthalate), PS (polystyrene) or PC (polycarbonate); or fibre reinforced polymers; or light metals, such as aluminium.
  • thermoplastic polymers such as PP (polypropylene), PE (polyethylene), POM (polyoxymethylene), PVC (polyvinyl chloride), PBT (
  • the fastening device according to the present invention may be made in any suitable way, such as by cutting a body of the material of choice.
  • the fastening device according to the present invention may be manufactured by pressure moulding of a light metal, such as aluminium.
  • a light metal such as aluminium.
