Definitions

• the present invention relates to a system for elevating and lowering a light and/or vision impeding arrangement such as a blind.
• Blinds traditionally hang at the top of a window and are lowered for use. The blind will then impede visibility and incidence of light from above and down, as the blind is lowered in of in front of the window.
• a first system where the blind is mounted in the wall over a window and where the mechanism for elevating and lowering the blind is held in a closed bar extending over the window.
• the elevation and lowering device of this system can be integrated in the window frame.
• This system can also be used with stand-alone windows not being mounted in a wall.
• blind it is meant a number of parallel lamellas being tillable to adjust the degree of visibility and incidence of light.
• the present system or arrangement is well suited for plisse curtains or the like.
• a string system for elevating and lowering the blind in addition to a string system for elevating and lowering the blind, it is requisite to provide a system for tilting the blinds.
• window panes in general and especially in stand-alone windows it is desirable to give an open impression when the blind is folded down in the lower part of the window frame. Therefore, strings for elevating and lowering the blind passing over the open window surface are not desirable.
• the invention relates to a system for elevation and lowering of a light and/or vision impeding arrangement such as a blind or the like which is arranged in a frame comprising an upper and a lower horizontal profile and two transverse or perpendicular profiles arranged to form a quadrangle frame.
• the system further comprises a rod or other elongate element from which guiding strings are suspended.
• a blind is also connected to the rod.
• the rod is further connected with an elevation and lowering mechanism lifting and lowering the rod simultaneously with the blind being lifted or lowered.
• the rod is connected to two devices arranged in the transverse profiles whereby the blind is lifted or lowered when the devices are lifted or lowered.
• a movable device such as a carrier is attached to a belt being connected to at least one drive wheel moving the belt.
• the movable device comprises a rotatable wheel being connected to the belt in such a way that the rotatable wheel can rotate when the belt is moving.
• the rotatable wheel arranged in or at the carrier is connected to the rod in such a way that when the rotatable wheel is rotating, the guiding string will be lifted or lowered respectively so that the lamellas of the blind are tilted to one side or the other.
• the system according to the invention can also comprise a motor with at least one protruding shaft.
• the shaft and, if appropriate, the motor is arranged in the upper horizontal profile in such a way that the shaft or shafts is/are in contact with the upper drive wheels being arranged in the two upper corners of the frame, in such a way that the drive wheels rotate when the shaft or shafts rotate.
• a U-formed profile is arranged partly surrounding the rod.
• the profile is provided with supporting brackets being attached to the profile in such a way that a part of the profile and one bracket together form an enclosure for a part of the rod.
• a system or arrangement according to the invention comprises a blind being attached at the lowest part of the window.
• the blind can be elevated for use to prevent visibility in the lower section of the window, while it allows light to enter through the upper section.
• the lamellas of the blind can be parked in any intermediate position and be tilted to any angle.
• the blind arrangement furthermore comprises a frame wherein the mechanism for elevation and lowering is mounted.
• the upper edge of the blind is attached to a transverse strip or rod that can be lifted or lowered by the elevation and lowering mechanism. Thereby, there will not be any part of the elevation and lowering mechanism over the upper edge of the blind.
• Fig. 1 shows a perspective view of the system according to the invention.
• Fig. 2 shows a cross section of the elevation and lowering system.
• Fig. 3 shows a cross section of the blind being attached to the elevation and lowering mechanism.
• Fig. 4 shows a cross section of a part of the blind arrangement.
• Fig. 1 shows a perspective view of the arrangement according to the invention.
• a window frame with an arrangement according to the invention comprises four profiles; an upper profile 1 and a lower profile 11 being paralle to each other and two transverse profiles 4 parallel to each other and perpendicular to the upper 1 and lower profile 11.
• the profiles are only partly shown in the figure.
• the four profiles extend over the length of the blind arrangement and will form a quadrangular frame.
• the profiles can for example be made of extruded aluminium or rolled steel plates being folded and/or welded together.
• the material used for the profiles should be rustproof and preferably of a certain strength. High-strength plastic material might also be useable for the window frame or other parts of the arrangement.
• a strap or belt 5 is arranged in each of the vertical profiles.
• the belts can be a transmission belt, toothed belt, friction belt, chain, wedge belt or the like being suitable for running one or more wheels or other rotating elements such as a shaft or rod.
• the belts 5 are arranged on and gripping upper and lower drive wheels 3 being provided in the corners of the frame.
• a motor 10 is mounted in the upper horizontal profile.
• the motor run the drive wheels 3 via two shafts 13 or one long shaft passing thorugh the motor 10. If there are two shafts 13, they will project from the motor on each side of the motor.
• the two upper drive wheels 3 are synchromesh and will enable a completely or principally parallel lifting and lowering of the two mounting regions of the upper edge of the light and vision hindering device, e.g. the blind.
• a shaft 12 can be arranged connecting the lower drive wheels 3, but this is not necessary for the invention to function in accordance with the intentions.
• a transporting or carrying device such as a carriage or carrier 6 is arranged on each of the belts 5 as shown in figure 1, 2 and 3.
• the free ends of the belts 5 are coupled to the carrier 6 through openings or slots 17 in the carrier 6.
• the drive wheels 3 When the motor is running, the drive wheels 3 will turn and the carrier 6 will move upwards and downwards in the profiles 4. As the carrier is lifted or lowered, the belt 5 will pass upwards and downwards through the passage 16.
• a rotatable wheel 7 is arranged in the carriers 6 in movable contact with the belt 5 e.g. by friction. When the belt 5 moves through the passage 16, it will start rotation of the rotatable wheel 7.
• the rotatable wheel is arranged so that it will slide when a given resistance is reached, for example when the lamellas of the blind reaches their maximum angle.
• the rotatable wheel 7 holds a shaft or rod 8 forming the upper part of the blind where the attachment strings for holding the lamellas 9 are arranged, preferably in a permanent way.
• the rod 8 is advantageously made from a sylindrical element such as tube, for example made of light metal.
• the motor When the motor is running, it will turn the shaft 13, which in turn rotates the upper drive wheels 3 moving the belt 5, so that the carriers 6 where the blind is attached, are elevated or lowered.
• the motor When a desired level of the blind is reached, the motor is stopped or reversed as the motor also can be used for adjusting the angle of the lamellas.
• Figure 2 shows how the blind is arranged in the system or arrangement according to the invention.
• the carriers 6 When the motor is rotating, the carriers 6 will be elevated or lowered.
• the shaft 8 following the movement of the carrier 6 will rotate together with the wheels 7 as described above. Due to this rotation, a guiding string 18 provided in the blind will be pulled towards one or the other side and the lamellas 9 in the blind will move or tilt from side to side so that the blind will close or open.
• the lamellas can be arranged or tilted in any desired position by running the motor back and forth.
• U-formed profile or moulding 19 partly surrounding the rod 8, as shown in fig. 4.
• the profile 19 will extend from one of the vertical frame profile 4 to the other vertical profile 4.
• the profile 19 can be attached to the carriers 6 over the rod 8.
• the blind is hanging from the rod 8.
• the tube-shaped rod can be supported by means of the profile 19, being attached on each side of the carriers 6.
• Small holders or brackets 20 are provided in the profile, uniformly distributed over the length of the profile 19 and supporting the rod 8. This will prevent the rod 8 from distorting over time due to the weight of the blind, as the brackets contribute to weight distribution and bracing over the connecting points.
• the belts 5 are extending over the whole length of the vertical profiles 4.
• system or arrangement is shown for blinds of the lamella type, but the system or arrangement can also be used with other light and/or visibility preventing devices such as fold or plisse curtains.
