Definitions

  • This invention relates to a system for mounting for a roller of an architectural opening and parts of the system.
  • Various blinds are known for selectively covering architectural openings. Many of these include rollers that are rotatably mounted, usually in a horizontal orientation, for instance across the top of an architectural opening.
  • an arrangement may be provided whereby a pair of brackets is mounted on opposite ends of a top frame of an architectural opening. The roller is than fitted between the two brackets.
  • the ends of the roller may be provided with co-axially extending end plugs with axial holes for receiving a tab-like projection from the brackets
  • the ends of the roller may be provided with co-axially extending end plugs and the end plugs being provided with axially projecting tabs or noses for insertion into an opening in a bracket.
  • the central shaft of the roller blinds may be coupled together end the end plugs may be provided with such shaft coupling means to be mounted to an intermediate bracket.
  • the distance between the ends of the roller must be greater than that between the brackets.
  • Providing a roller with at least one telescopically movable end plug solves this problem. Retracted or depressed, such an end plug reduces the effective length of the roller and the distance between the two ends of the roller, extended the end plug restores the roller to its original length. Additional locking means preventing inadvertent retraction or depression of the telescopically movable end plug and thus inadvertent disengagement of the roller from the brackets are often also provided and are described in GB 2,310,878 and in GB 2,313,143 .
  • GB 2,310,878 describes an end plug (20) for a roller blind including a telescopic movable drum (6) biased to an extended position by spring (30).
  • the locking means comprises a spring C-clip (40), positionable about the projecting portion (7) of the telescopic movable drum (6) between the roller end (23) and the end (8) of the drum (6), and prevents the telescopic member (6) from moving axially into end plug (20).
  • This solution has as drawback that the C-clip (40) needs to be dimensioned in relation to the blind for which it is used. If it is to long, exceeding the length of the projecting portion of the telescopic member of the end plug, it will not fit.
  • GB 2,313,143 describes a locking ring (100) for placement about a telescopic movable spigot (54), which is biased to an extended position by a spring.
  • the locking ring (100) is placed about the spigot (54), is pushed until it makes contact with the roller end (10) remote from the bracket (80), and is locked in place with a grub screw.
  • the ring has a radial through hole (102) with the grub screw (104), which when tightened locks the ring (100) in place.
  • the ring (100) prevents depression of the spigot (54) and thus prevents accidental removal of the blind from its brackets.
  • an object of the invention is to provide a roller mount system with a end plug module which overcomes or ameliorates the disadvantages of the end plugs of both GB 2,310,878 and GB 2,313,143 .
  • the blind includes side guides, which is often the case for insect screens and black-out roller blinds, the screen or blind material edges will not keep to the side guides. As a result insects and/or light will enter the building.
  • the blind is leveled by using the oblong mounting holes in the brackets of the blind. After-adjustment of the bracket's position, requires nimble hands and/or dismounting of the roller from the brackets to facilitate reaching an manipulating it. It generally is a cumbersome process.
  • Another solution is to use brackets with integrated leveler means that act directly or indirectly on the roller of the blind. Such brackets are described in US 6 196 508 and DE 103 51 336 .
  • US 6,196,508 describes a roller blind bracket with a centrally located cut out portion (11) with slidably located a vertically adjustable glide (4) which rests on a threaded leveling screw (5).
  • the threaded leveling screw (5) can be accessed from the bottom of the bracket.
  • the glide (4) is omitted and the leveling screw (5) acts directly on the steel rod of the motor.
  • the leveling screw (5) acts directly on the steel rod of the motor.
  • DE 103 510 336 describes a insect screen roller blind with a leveler (22) in a roller bearing (14) which includes a cut out portion (28) and a leveling screw (34) acting on the roller spigot (30).
  • each leveler necessarily includes a base to be anchored to a fixed surface such as a bracket and an operator connected to that base, movable between two positions, and acting either directly or indirectly on a roller end in order to move the roller between these two positions.
  • the use of the known prior art levelers requires either a preordained choice of using a bracket with integral leveler, or leads to a very cumbersome after-installment of the leveler once it is needed after all.
  • An embodiment of the invention comprises a leveler module for the roller mount system which does not have these drawbacks and is easy to manipulate.
  • Another problem associated with mounting a roller to a surface are the brackets.
  • the bracket When a roller blind is mounted to a roof window or sunroom window that is slanted, the bracket will cause the blind to be at an angle to the window unless a specially shaped bracket is used which cancels out the window frame angle.
  • a bracket is described in EP0784145 , this bracket includes adjusting means that can cancel out the angles of the window relative to that of the blind.
  • it is often necessary to choose different modules for a roller system often require different brackets.
  • an intermediate bracket in a compound roller system having at least two rollers mounted next to each other is often of different configuration from the outer bracket.
  • DE 20 2004 015105 U1 describes the features of the precharacterising portion of appended claim 1.
  • a telescopic end plug as defined in appended claim 1.
  • a roller blind mounting system according to the present claim 2.
  • the telescopic end plug further has a rotatable end cap rotatably fixed to the end of the second length portion and the end cap is adapted be received in the central aperture of the bracket such that the telescopic end plug and the roller engageable therewith are rotatably mountable to said bracket.
  • the bracket further includes at least a pair of openings positioned about said central aperture and the opening of each pair being in line with each other, and the mounting system further includes an operating module or a leveler module, or both, provided with mounting means adapted to co-operate with the at least one pair of slots of the bracket.
  • the mounting means are hook-like members adapted to project through the openings of the bracket and grip the rim of the openings.
  • the hooks each include a stem portion and a grip portion extending from the top of the stem portion.
  • the grip portion of the hook extends sideways from the top of the stem portion.
  • the grip portion of the hook extends downwardly from the stem portion.
  • the invention thus solves the problems associated with mounting of roller blinds .
  • a roller blind 1 is shown with roller 3 mounted between a left and right mounting bracket 5, 7.
  • the blind material 9 is schematically indicated and can be wound and unwound from the roller 3 by operating the bead chain operating mechanism 11.
  • a telescopic end plug 13 in the right end 3A of the roller 3 facilitates mounting of the roller 3. Depressing the end plug 13 reduces the effective length of the roller 3 making it easy to position between the two brackets 5,7. Retracting the end plug 13 to its extended position restores the roller 3 to its previous length, allowing the roller 3 to connect to the left and right brackets 5,7 by suitable end plugs on either side.
  • a locking ring 15 prevents the inadvertent depression of the telescopic end plug 13. In figure 1 the ring 15 is shown in the unlocked position, adjacent the outer end of the telescopic end plug 13. By positioning the ring 15 adjacent the roller end 3A, depression of the telescopic end plug 13 is prevented.

  • the tongues 71, 73, 75 can be slidably retained in the axial passage ways 51, 53 defined between the retainer 39 and the body 21. Movement of the plunger 61 in axial direction is possible because the tongues 71, 73, 75 move within the axial passage ways 51, 53.
  • the plunger tongues 71, 73, 75 can extend beyond the left end 29 of the body 21 when plunger is deeply inserted into the body 21.
  • the tongues 71, 73, 75 each include a lug 73A at the axial end away from the base 61 on the outer surface of the tongues which cooperates with an indented portion 29A of the inner axial end 29 of the cylindrical body 21. Inserted into the cylindrical body 21, the lugs 73A snap behind the indented portion 29A and thus prevent disengagement of the plunger from the body 21.
  • the right or outer part 65 of the plunger 23 projects axially from the base 61 opposite from the inner part 63.
  • the outer part 65 is provided with a circumferential screw thread 77 with a plurality of windings 79.

  • Additional locking means 258, 270,272 are provided between on mounting tray 202 and the rest of the leveler module which prevent the tray 202 from rotating on its own accord (e.g. caused by vibration or by operation of the blind 1 or the like) in the opposite direction and thus disengaging the leveler 200 from the bracket 7.
  • These locking means 258, 270, 272 are described in relation to Figure 7 .
  • the leveler module 200 can thus be easily, even single handedly, mounted to a bracket 7 similar to a bayonet type quick release mechanisms. This is particularly convenient, for after-installment thereof. It also makes expensive bracket with integrally formed levelers obsolete.

As shown in figures 5 and 6 there are eight radially distributed openings 115 for the leveler 200 to be mounted to.
