Definitions

  • the present invention relates to a roll blind provided with an exchangeable sleeve to which the upper end of a screen is fixed.
  • the sleeve is removably mounted on a roller rotatably supported by a pair of brackets.
  • the roll blind has a screen wound on a roller which is rotatably supported by a pair of brackets.
  • the screen has its upper end directly adhered on the surface of the roller by the use of an adhesive or fixed to a bar which is inserted from side to side into the grove or slit in the roller.
  • the used screen is unable to be replaced by a new one, when it is adhered to the roller.
  • the used screen can be substituted for a fresh one when the screen is not adhered to the roller but attached to the bar.
  • the screen is desirably changeable according to user's preference. Therefore, there is a demand for a roll blind of which the screen can easily be exchanged without special tools.
  • the present invention as claimed is intended to comply with the demand and provide an roll blind in which a screen is easily changeable.
  • the roll blind comprises a roller of which the opposite ends are rotatably supported by both brackets, a sleeve fitted on the roller for rotation therewith, and a screen of which the upper end is attached to the outer periphery of the sleeve.
  • the roller is formed on the outer periphery thereof with a connecting element, such as an axial groove and an axial projection, for coupling engagement with the other connecting element, such as an axial groove, an axial slit and an axial projection, formed in the inner periphery of the sleeve.
  • the inner diameter of the sleeve is slightly larger than the outer diameter of the roller, so that the former is smoothly fitted from side to side on the latter.
  • the split type sleeve can have its inner diameter slightly larger than the outer diameter of the roller to resiliently fit on the roller.
  • the sleeve is axially slipped on and out of the roller with ease.
  • the both connecting elements can couple each other to rotate the sleeve and the roller as one body. An axial movement of the sleeve relative to the roller is prevented by the connecting elements coupled or an removable stopper provided on the side end of the roller.
  • a variety of screens are previously fixed to the respective sleeves for supply to users.
  • the advantages offered by the invention are mainly that the screen in the roll blind can be changed without troublesome operations such as removing a used screen against an adhesive and dismounting a bar with a used screen from the roller, and that a variety of screens can be offered separately from the roller of a roll blind. All in all, one can freely change the screen according to his preference.
  • a screen 10 is wound on a sleeve 20, which is fitted on a roller 30 rotatably supported by opposite brackets 40.
  • the sleeve 20 is formed on its inner surface with thick portions 22 each being provided with an axial groove 21 as a connecting element.
  • the roller 30 is formed on its outer surface with axial projections 31 as the other connecting element in mesh with the respective axial grooves 21 in the sleeve 20, thereby the roller 30 and the sleeve 20 rotating as one body.
  • the sleeve 20 is made from a synthetic resin material such as vinyl chloride.
  • the roller 30 of metal or synthetic resin has its outer diameter slightly smaller than the inner diameter of the sleeve 20, thereby the latter being smoothly slidable from side to side on the former.
  • the sleeve 20 is formed on its inner periphery with a plurality of radially swelled portions 22 each extending axially from one end to the other end to have an axial groove 21 in the middle thereof.
  • the screen 10 has its upper end adhered to the outer surface of the sleeve 20.
  • a fixed shaft 41 projects from one of the both end caps 36 and 37 mounted on the opposite side ends of the roller 30, a rotary. shaft 42 projecting from the other.
  • the rotary shaft 42 is rotatably supported by the bracket of FIG. 1, the fixed shaft being fixedly supported by the other non-illustrated bracket.
  • the roller 30 is formed on its outer periphery with a plurality of the projections 31 disposed between the both end caps 36 and 37 for coupling engagement with the grooves in the inner periphery of the sleeve of FIG. 2.
  • the axial length of the projection 31 is not always similar to but much less than the length of the roller.
  • the sleeve 20 is smoothly slided from side to side on the roller 30,having the grooves 21 guided by the respective projections 31. The sleeve 20 is easily slipped on and off from the roller 30.
  • a stopper ring 35 is removably mounted of the end cap 36 with a set screw to prevent the sleeve 20 from axially sliding on the roller 30 when the both connecting elements of the sleeve and the roller are loosely coupled with each other.
  • the groove in the sleeve and the projection on the roller are not limitative but exchangeable to each other.
  • the groove 32 can be formed in the outer periphery of the roller and the projection 22 can be provided on the inner periphery of the sleeve 20.
  • the sleeve 20 is formed in its opposite end portions with a pair of slits 23, 23 while the roller 30 is provided on the both end caps 36, 37 with two pawls 33, 33 coupling engagement with the respective slits, at least one of the pawls being removable.
  • the sleeve 20 is slipped on the roller 30 to one end cap 37 from the other end cap 36 in which the pawl 33 is removed. Thereafter, the the sleeve 20 has been fixed to the roller 30 with the slits 23, 23 in mesh with the pawls 33, 33.
  • the sleeve 20 is somewhat loosely fitted on the roller 30 but surely rotates together with the roller 30 by the virtue of the coupling engagement between the slit 23 and the pawl 33.
  • the sleeve 20 is easily slipped on and off from the roller 30 when the pawl 33 is removed.
  • the end cap 36 is integrally provided with a pawl 33 for coupling engagement with the associated slit 23 in the sleeve 20 when it is removably fixed to the roller 30 by the use of set screws.
  • the end cap 36 is dismounted from and mounted on whenever the screen is changed.
  • the roller 30 has a leaf spring 34 embedded in a groove 38 with an axially enlarged bottom.
  • the leaf spring 34 has its middle part projected radially outwardly from the surface of the roller 30.
  • the sleeve 20 in the form of a split pipe has a split gap 24 resiliently nipping the middle part of the leaf spring 34, thereby rotating with the roller as one body.
  • the sleeve 20 has its inner diameter equal to or slightly smaller than the outer diameter of the roller 30, therefore the split gap 24 having its intermediate portion smaller than the opposite end portions nipping the leaf spring 34.
  • the inner diameter of the sleeve 20 is slightly smaller than the outer diameter of the roller 30, the former is smoothly slipped on and off from the roller 30 from side to side. The reason for this is that the diameter of the sleeve 20 is resiliently expansible and that the leaf spring 34 is easy to sink in the roller 30 when is is pressed.
  • the changing operation of a used screen to a new one is easy: it starts from removing the roller from the brackets. Then, pawls and stopper rings are removed from the roller if provided. The used sleeve with the used screen is slided from side to side and slipped off from the roller. Thereafter, the new sleeve with the fresh screen is fitted on the roller and slided from side to side until the both connecting elements are coupled with each other. Then the pawls and the stopper rings are mounted on the roller if provided. Finally, the roller is reset in the brackets.
