Definitions

  • This invention relates to a venetian blind, and especially to a raising mechanism for a venetian blind.
  • Venetian blinds have a top and bottom bar.
  • the top bar may be attached to the upper portion of a window frame, or similar mounting point.
  • the bottom bar is suspended beneath the top bar using the pulling cords of the raising mechanisms.
  • Horizontal slats are suspended between the top and bottom bar. By tilting the inclination angle of the horizontal slats the amount of light passing through the window may be adjusted. If desired, the venetian blind may also be raised to allow full access to the window.
  • an operator may pull on a cord, or a number of cords bundled together. This action raises a bottom bar of the blind towards a top bar by drawing a cord towards the top bar.
  • the horizontal slats gather on the bottom bar as the bottom bar contacts each slat, thus opening the blind.
  • a venetian blind having a top bar, a bottom bar, horizontal slats disposed between said top and bottom bars, a raising mechanism for adjusting the height of a bottom bar of said venetian blind, wherein said raising mechanism comprises:
  • the first and second member may be any element which allows cord to pass over the element, without undue frictional resistance.
  • the cord is attached to the top bar of the blind assembly. Even more preferably the cord is attached adjacent to the first member attached to the top bar.
  • the first member may be one of a plurality of like members attached to the top bar and the cord is fed past the members attached to the top bar.
  • the second member may be one of a plurality of like members attached to the bottom bar, and the cord is fed past the members attached to the bottom bar.
  • the members are rotatable members.
  • the members rotate with the motion of the cord passing thereover.
  • the members are pulleys.
  • the venetian blind is provided with at least two raising mechanisms.
  • the venetian blind is provided with a further member for receiving the cords of the raising mechanisms.
  • the further member is a rotatable member.
  • the further member rotates with the motion of the cords passing thereover.
  • the further member is a pulley.
  • Figure 1 depicts a conventional venetian blind assembly 150, having a top bar 121 and a bottom bar 120, horizontal slats 135, an aggregate cord 125 and raising mechanisms 130, 131.
  • the raising mechanisms 130, 131 have a pulley 111, 113, and a pulling cords 160, 161 attached to bottom bar 120.
  • the pulling cords 160, 161 both pass the secondary pulley 115, and form the aggregate cord 125.
  • displacement of the aggregate cord 125 translates to equal displacement of the bottom bar 120.
  • Figure 2 depicts a blind assembly 50 with the bottom bar 20 in the lowest position.
  • the top bar 21 of the blind assembly 50 may be attached above a window (not shown).
  • Horizontal slats 35 are distributed between the bottom bar 20 and the top bar 21.
  • Figure 3 depicts the blind assembly 50 in figure 2 in a partially open position, with the bottom bar 20 located between the highest position and the lowest position. As the bottom bar 20 is raised, the slats 35 are progressively gathered on the bottom bar 20. Thus the slats 35 are raised with the bottom bar 20.
  • the aggregate cord 25 is made up of pulling cords 1 and 2, which are respectively associated with raising mechanisms 30 and 31. Both pulling cords 1, 2 are attached to the top bar 21 at the attachment points 5 and 6. The attachment points 5, 6 are located adjacent to the corresponding upper primary pulleys 11, 13. From attachment point 5, pulling cord 1 first passes around lower primary pulley 10, which is fixed to the bottom bar 20. Pulling cord 1 then passes around upper primary pulley 11 fixed to the top bar 21.
  • pulling cord 2 first passes around lower primary pulley 12 fixed to the bottom bar 20 and then passes upper primary pulley 13 fixed to the top bar 21. Both pulling cords 1, 2 then pass around the secondary pulley 15, at which point aggregate cord 25 is formed.
  • the pulling cords 1, 2 have a generally vertical orientation.
  • the bottom bar 20 is suspended from the attachment points 5, 6 and the upper primary pulleys 11, 13.
  • the suspended mass of the gathered slats and the bottom bar 20 is supported by four suspension points (the fixed points 5, 6 and the upper primary pulleys 11, 13).
  • Pulling cords 1, 2 transfer the weight force of the suspended mass applied to the respective upper primary pulleys 11, 13 to the secondary pulley 15, and ultimately to aggregate cord 25.
  • the force required on aggregate cord 25 to hold the blind in position is half the weight force of the suspended mass. Displacement of the aggregate cord 25 is greater than the displacement of the bottom bar 20.
  • FIG. 4 shows a blind assembly 50 with two raising mechanisms.
  • the top bar 21 has upper primary pulleys 11, 13 which also provide attachment points 5, 6 for the pulling cords 1, 2.
  • the secondary pulley 15 is attached near the end of the top bar 21, such that an operator may operate aggregate cord 25 remotely from the raising mechanisms.
