Definitions

  • an object of the present invention to overcome or ameliorate at least one of the disadvantages of the prior art. It is also an object of the present invention to provide alternative structures which are less cumbersome in assembly and operation and which moreover can be made relatively inexpensively. It is also a general object of this invention to improve the quality of life at an office by offering an improved thermal and visual comfort, through an improved balance between the building, the climate and the occupant. It is a more specific object of the present invention to to provide a window covering that optimises the distribution of natural lighting in a. room, while also minimizing light reflections on computer display screens. More in particular it is an object of the window covering according to the invention to allow the user a maximum in flexibility of adjustments, so as to achieve protection against too much light and glare from sunlight while at the same time maintaining an optimum level of natural light.
  • a window covering comprising:
  • the blind according to the invention features two mutually independent movements.
  • a first of these movements allows for screening the sunlight at any position of the sun, by extending a flexible sun screening member over a variable trajectory.
  • a second movement sets the height of the extended sun screening member.
  • an adjustable area can be set so as to allow natural light into the room.
  • the electrical adjustment can have a motorised operation connected to a system of automatic control.
  • the window covering according to the invention will lead to a better level of thermal and visual comfort and to a better balance between natural and artificial light and thereby result in energy savings on heating, lighting and cooling.
  • a window covering 1 is shown in use adjacent to a framed window opening 2.
  • the window covering 1 is in the form of a roller blind and is mounted on a wall surface 3 surrounding the window opening 2.
  • the window opening 2 has a frame with the usual upper and lower horizontal frame members 2a, 2b and opposite vertical side frame members 2c, 2d.
  • the window covering 1 includes an upper head box 4 which is fixed to wall surface 3 in the vincinity of the upper horizontal frame member 2a.
  • the upper head box 4 has first and second end caps 5 and 6, which are connected to support brackets 7 and 8. Extending downwardly from each end cap 5, 6 is a guide rod 9, 10 respectively, that serve as lateral guides for a blind roller 13.
  • Each of these guide rods 9, 10 extends downwardly for a limited portion of the height of the window opening 2 and is preferably anchored at its lower end by a wall mount attachment 11
  • the head box 4 houses an operating mechanism that will be derscribed in relation to notably Figures 4 and 9 hereinbelow.
  • Mounted for up and down movement along the lateral guides 9, 10 is a roller 13 onto, or from, which a flexible window covering sheet 15 can be rolled or unrolled, respectively.
  • a roller 13 is mounted for up and down movement along the lateral guides 9, 10 a roller 13 onto, or from, which a flexible window covering sheet 15 can be rolled or unrolled, respectively.
  • a roller 13 Along a lower edge of the flexible sheet 15 extends an elongate bottom bar 17, provided on its opposite longitudinal ends with longitudinally projecting stop pins 19, 20.
  • These protruding pins 19, 20 can be engaged with confronting bottom bar latches 21, 22 to retain the bottom bar 17 in its lowered position.
  • the roller 13 is spring biased for rolling-
  • additional bottom bar latches 23, 24 are provided at a suitable location in-between the latches 21, 22 and the fixed head box 4.
  • FIG 2 is a perspective detail view of the upper head box 4 as seen from above.
  • the fixed upper head box 4 comprises an attachment profile 25.
  • This attachment profile 25 is closed of at its ends by the end caps 5, 6 as explained in Figure 1 and also forms a unit with the support brackets 7, 8.
  • a removable cover profile 27 which is preferably designed to form a snugly fitting transition between the attachment profile 25 and the bottom bar 17 in its fully raised position.
  • a bottom bar stop 29 is provided on at least one longitudinal end of the roller 13, but preferably on both longitudinal ends thereof.
  • Figure 3 shows the detail III from Figure 1 on an enlarged scale.
  • the bottom bar latch 21 has a recess 31 for locating the bottom bar stop pin 19.
  • FIG 4 is an enlarged detail of a top left hand corner of the window covering of Figure 1, but with the cover profile of the head box removed to show the internal mechanism.
  • the roller 13 is shown in a somewhat lowered position with respect to the head box 4.
  • the blind roller 13 has a conventional spring motor for rolling up the screen cover 15.
  • the centrifugal stopping mechanism conventional for such spring roller blinds can be eliminated in view of the bottom bar latches 21, 22, 23, 24.
  • the opposite longitudinal ends of the roller 13 are mounted in roller end mounts, such as end mount 33.
  • the end mount slidably engages the guiding rod 9 for movement from and to the head box 4 in a vertical direction.
  • the roller end mounts at each opposite end of roller 13 are also suspended by transporting cables 35 and 37 respectively.
  • Transportation cables 35, 37 can each be wound or unwound from respective winding pulleys 39, 41. These winding pulleys can be driven in each of two opposite directions of rotation by a common drive shaft (not shown but conventional).
  • This common drive shaft is so driven by an electric motor, which can be any suitable type of commercial tube motor.
  • the motor 43 is of a type as supplied by BECKER-Antriebe GmbH and designated 5/20S, or of a type supplied by Somfy and designated LS40. These motors can be combined with various electrical controls.
  • a suitable number of guide pulleys 45, 47 and 49 are rotatably mounted on the attachment profile 25 of the head box 4.
  • the guide pulley at the second cap 6 (not shown in Figure 4) is similar to guide pulley 45 and generally in a mirror-image arrangement.
  • Figure 4A is a partial perspective view, somewhat similar to Figure 4, showing a modified operating mechanism for raising and lowering the roller.
  • the embodiment of Figure 4A provides for a slightly more compact arrangement of components within headbox 4A.
  • End cap 5A, support bracket 7A and guide rod 9A are generally similar to those in the embodiment of Figure 4.
  • the attachment profile 25A mounts the guide pulleys 47A and 48A in a slightly different orientation with respect to winding pulleys 39A and 41A.
  • the headbox 4A in Figure 4A is shown, for clarity, without the transportation cables and without the blind roller suspended therefrom. Without these transportation cablesit is seen that the winding pulleys 39A and 41A each have a stepped core surface 51 and 53, respectively.
  • this stepped core surface greatly assists in forming the initial windings of the transportation cables, while preventing successive windings to become entangled. This is particularly helpful if the guide pulleys (47A, 49A) are positioned close to the winding pulleys (39A, 41A).
  • the bottom bar 17 can be manually engaged with the bottom bar latch 21, or the additional bottom bar latch 23. Also shown in Figures 5 through 8 is that the roller 13 can be moved between a lower most position and a raised position in which it abuts the head box 4. Since the flexible covering sheet 15 is rolled and unrolled from the spring biased roller 13, the up and down movement of the latter is independent from the position of bottom 17.
  • the manually adjustable position of the bottom bar 17 is chosen by persons occupying a windowed room fitted with the window covering 1, in accordance with their preferred comfort.
  • the position of the roller 13 is controlled automatically in response to a predetermined amount of illumination required in the subject room. This proposed arrangement results in a very efficient and convenient window covering product, allowing individual settings for creature comfort, while alleviating the difficult task of administering daylight illumination.
  • Step 101 represents the manual action of bringing the bottom bar in an operative position.
  • Step 102 represents the action of starting the automatic operating sequence. Both steps 101 and 102 are not part of the normal operating sequence and are merely represented in Figure 9 for the sake of completeness.
  • the automatic operating cycle is governed by a time interval generator 103, which generates a delay of preferably several minutes of time between subsequent light level measurements to be carried out by the system.
  • the timer 103 initializes the determination in step 104 of the azimuth position of the sun in accordance with the time, date and location to decide whether or not there could be direct sunlight impinging on the window (2 of Figure 1). When there cannot be any direct sunlight, the program progresses to step 105 to measure the level of light available at the window.
  • step 107 the roller 13 is moved from its initially raised position to the lowermost position, after which the next measurement and adjustment cycle is awaited. If at step 106 the light level is determined to be higher than the first range, then the program proceeds to step 108, which determines whether the light level falls within a second range (i.e. of 15000-40000 Lux). When this is the case step 109 will adjust the roller to a first intermediate position, higeher than its lowermost position. With a level of light still higher than the second range the program will proceed to step 110, which detects whether the light level falls within a third range (i.e. within 40000 to 60000 Lux). When this is the case step 111 will adjust the roller to a second intermediate position, higher than the first intermediate position.
  • a third range i.e. within 40000 to 60000 Lux
  • the roller With the light level still higher than the third range (i.e. over 60000 lux) the roller will remain in its initial upper-most position.
  • step 104 detects that there could be direct sunlight the program proceeds to step 112, for measuring the amount of light impinging on the window (2 in Figure 1). If the amount of light falling on the window is within a first range (i.e. 0-15000 lux), step 113 directs the program to step 114, which determines the altitude of the sun. If the altitude of the sun is in a first low angle range (i.e. 5-15 degrees) then step 115 adjusts the roller 13 from the initial upper-most to the lowermost position. With the sun at a steeper angle of altitude the program will proceed to step 116, which detects whether the altitude is within a second range (i.e.
  • step 118 will adjust the position of roller 13 to a first intermediate position higher than the lowermost position.
  • step 117 which adjusts the roller to a second intermediate position, higher than the first intermediate position.
  • step 113 determines that the level of light exceeds the first range the program proceeds to step 119.
  • Step 119 determines whether the level of daylight is within a second range (i.e. of 15000-40000 lux). If the amount of light falling on the window is within this second range, step 119 directs the program to step 120, which determines the altitude of the sun. If the altitude of the sun is in a first low angle range (i.e. 5-15 degrees) then step 121 adjusts the roller 13 from the initial upper-most to the lowermost position. With the sun at a steeper angle of altitude the program will proceed to step 122, which detects whether the altitude is within a second range (i.e. 15-45 degrees).
  • a second range i.e. 15-45 degrees
  • step 124 will adjust the position of roller 13 to a first intermediate position higher than the lowermost position.
  • the program will proceed to step 123, which adjusts the roller to a second intermediate position, higher than the first intermediate position.
  • step 119 determines that the level of light exceeds the first range the program proceeds to step 125.
  • Step 125 determines whether the level of daylight is within a third range (i.e. of 40000-60000 lux). If the amount of light falling on the window is within this third range (i.e. 40000-60000 lux), step 125 directs the program to step 126, which determines the altitude of the sun. If the altitude of the sun is in a first low angle range (i.e. 5-15 degrees) then step 127 adjusts the roller 13 from the initial upper-most to the lowermost position. With the sun at a steeper angle of altitude the program will proceed to step 128, which detects whether the altitude is within a second range (i.e. 15-45 degrees).
  • step 130 will adjust the position of roller 13 to a first intermediate position higher than the lowermost position.
  • the program will proceed to step 129, which adjusts the roller to a second intermediate position, higher than the first intermediate position.
  • step 125 determines that the level of daylight exceeds the third range (i.e. exceeds 60,000 Lux), then the roller 13 will be kept in its initial upper-most position, or be moved thereto if it was in any of the lowered positions due to a previous adjustment.
  • roller 13 and the bottom bar 17 can be in an inversed arrangement, wherein the bottom bar 17 is at the to and the roller 13 at the bottom of the window covering.
