Definitions

  • the invention relates to blinds for windows, in which there are at least two separate panels of blind material, which may hang one behind the other or singly.
  • the panels can be adjusted for various light and shade effects , and can provide substantially complete black out if required, or can be drawn up to the headrail.
  • conventional blinds for windows have typically been either Venetian style blinds with transverse strips, or so called vertical blinds. These blinds could have a mechanism whereby the strips could be rotated between closed and open positions.
  • open position in which light is transmitted into the room, there was also a loss of privacy.
  • closed position In the closed position, the light was obscured, but never completely excluded.
  • blinds which simply consist of a panel of thick flexible material, wound onto a roller in a headrail.
  • the material can be pulled down for privacy, and to obscure the light, or raised, to allow passage of light, but with loss of privacy.
  • a continuous sheet of blind material may be provided, which hangs down double, over the window opening, and forms a loop.
  • the sheet is preferably somewhat translucent and is stored on a roller in the head rail. The free end of the sheet is fixed up in the head rail , and the other end of the sheet is attached to the roller in the head rail .
  • This material is light permeable, but provides privacy.
  • the material may have alternating bars or strips of more and less translucent material. When hanging in a loop the material will allow more light through the more translucent lighter strips and less through the less translucent darker strips.. By adjusting the loop it is possible to allow more light into the space.
  • the blind may incorporate a bottom rail which is weighted to keep the loop hanging down.
  • a free running guide roller may be incorporated in the bottom rail.
  • the loop runs freely, in the bottom rail, around the guide roller. In this way the material can be adjusted, or can be retracted right up into the head rail.
  • a second blind panel is stored in the head rail and is formed of opaque blackout material. When complete light exclusion is required this second panel can be lowered.
  • both blind panels are stored in the same head rail, on separate rollers.
  • blind header rail providing two rollers, for handling two such panels, and which may provide for relative movement between one portion of the first panel and another portion , and also the provision of the second roller for the second panel, presents numerous problems.
  • the head rail In the first place the head rail must be compact and aesthetically pleasing. Desirably the blind head rail shall occupy no more space, or only slightly more space at the top of the window opening than previously known blinds.
  • the operation of the separate blind panels must be simple and capable of being operated by either manual controls, or in the case of more complex designs by means of power controls, and even remotely operated power controls.
  • rollers will preferably be arranged as upper and lower rollers. Each roller would carry a blind panel.
  • the upper blind , on the upper roller, will be guided to pass around the lower roller, and separate from the lower blind on the lower roller.
  • the lower blind is a double panel , with a weighted bottom rail
  • the lower blind passes around a free running guide roller within the bottom rail.
  • the material continues to roll freely around the guide roller in the bottom rail.
  • control mechanism for the upper roller and control mechanism for the lower roller in the blind head rail by means which either or both of lower and upper panels can be operated up or down and by which both can be raised up out of the window opening, so as to leave the window opening clear and free of the blind all together, if desired.
  • the blind controls are usually chains or cords, hanging down from the headrail, and controlling the rollers.
  • Another problem is that when an operator manipulates the cords, the edges of the panels gradually become damaged. The appearance, and life, of the blind is therefor impaired.
  • a certain degree of friction may be inevitable, and may be acceptable in lower cost blinds, or may be reduced by the use of materials which generate less friction.
  • a blind has an upper roller with a black out shade
  • the lower blind is for example an accordion pleat blind, or a Venetian or vertical type blind
  • a lower blind attachment is of the type where the lower blind is not mounted on a roller., but is drawn up or lowered by control cords, or is simply drawn to one side as in the case of vertical blinds
  • the invention provides a blind for a building opening, and having a head rail, attachable adjacent the building opening, the head rail defining upper and lower regions, and having; an upper blind roller, located in the upper region of said head rail, a lower blind attachment located in the lower region of the head rail, an upper blind stored on the upper blind roller, a lower blind stored on the lower blind attachment, upper blind control mechanism operable to lower and raise the upper blind , lower blind control mechanism operable to operate the lower blind and to lower and raise the lower blind, wherein the upper blind roller is located with an upper axis along an upper plane in said head rail and the lower blind attachment is located on a lower axis along a lower plane within the head rail, the axes being displaced vertically from one another , and wherein the upper blind is operable to depend down beside a predetermined side of said lower blind attachment , and wherein the lower blind is operable to depend down alongside but spaced from side of the upper blind , whereby to provide a head
  • Control elements will be provided for operating both the lower and the upper blind, and guides in the head rail guide the elements to hang free of the lower and upper blinds.
  • the upper blind is an opaque black out blind
  • the lower blind is a semi translucent blind, whereby when the upper blind is raised and the lower blind is lowered, some light will pass in, and wherein when the upper blind is lowered light is substantially excluded.
  • the upper roller is located in an upper region of the head rail, and the lower bilnd attachment, which may be a linear elongate member , or a lower roller, depending on the type of lower blind, in located in a lower region of the head rail spaced vertically apart.
  • the lower bilnd attachment which may be a linear elongate member , or a lower roller, depending on the type of lower blind, in located in a lower region of the head rail spaced vertically apart.
  • the lower blind is a panel formed into a loop of material, and a lower blind bottom rail is provided, and having a free running roller, and in which the loop of the lower blind panel passes around the free running roller in the bottom rail.
  • the invention may provide such a blind in which the lower blind panel has a free end secured in the head rail , and a second end attached to the lower blind roller in the head rail.
  • Transverse blind strips alternating between light permeable or translucent strips, and less permeable or dark strips, are formed in the lower blind panel , at spaced intervals there across.
  • the bottom rail provides a mass weight to hold the loop of the lower blind panel in position.
  • Blind panel control mechanism in the head rail enables the lower blind panel to be adjusted so that one portion of the loop moves relative to the other. During such adjustment the blind panel material passes freely around the free running guide roller in the bottom rail In this way the alternating blind strips can be adjusted between open and closed positions.
  • the free end of the lower panel is attached within the head rail in a position such that contact between the two portions of the looped blind panel are kept to a minimum as far as possible.
  • An attachment wall may be incorporated in the head rail for holding the free end of the lower panel, free from contact with either the lower blind or the upper blind .
  • the bottom rail has a hollow channel shaped roller housing, defining an upwardly directed open mouth, and a free running roller located in said housing , said free running roller having a diameter greater than the width of said channel open mouth whereby to trap said roller within said housing.
  • a lower blind attachment may be in the form of a support wall which is secured to the front of the head rail, and extends partially towards the rear, with the lower blind secured to the support wall.
  • a space at the rear of the head rail permits the upper blind to depend freely down behind the lower blind.
