Definitions

  • This invention relates to a blind, particularly to one having an excellent efficiency and its assembling method.
  • Conventional blinds generally include a headrail, a bottomrail, a plurality of ladders and a plurality of lift cords combined between the headrail and the bottomrail, and a plurality of slats deposited in parallel between the headrail and the bottomrail.
  • Each slat is provided with a plurality of holes properly spaced apart in the intermediate portion for the lift cords to pass through to lift up the bottomrail so that all the slats may be lifted up sequentially, and the ladders change the angle of every slat in various degrees so that the light may be adjusted in its strength to pass through every gap between every two slats into a room or totally shut out.
  • the conventional blinds have a common flaw that light may enter a room a little through the gap between every two adjacent slats even if the slats are adjusted in the completely closed condition.
  • the lift cords located in the intermediate portion of all the slats may interfere with the changeable angle of each slat and prevent two neighboring slats from closely contacting each other, resulting in a very small gap between every two neighboring slats for light to pass through in a room.
  • a US patent No. 5,727,613 includes slats bored with no holes for lift cords but with a notch provided at two ends respectively, permitting every two neighboring slats to contact closely and vertically with each other when the blind is closed for shutting out light totally.
  • the blind disclosed in the US patent No. 5,727,613 has the slats possible to move left and right, not restricted as such that the slats may slide out of one side of the blind if the blind is inclined to one side (whether right or left).
  • US patents No. 4,951,729 , No. 5,386,867 and No. 6,792,996 have every slat bored with a hole near an end for a lift cord to pass through for preventing the slats from sliding out of a side of the blind.
  • the ends of each slat may hide the hole to reduce the volume of light passing there through, in addition to the function that the slats are prevented from sliding out of either side of the blind.
  • a US patent No. 5,582,226 discloses a blind provided with lift cords not passing through slats, but said slats still have a hole at two opposite sides and the ladders are twisted so that the slats may not turn smoothly. Moreover, after the bottomrail is lifted up for some distance, it may clearly interfere smooth turning of the slats.
  • US patent No. 6,105,655 discloses a hidden hole venetian type blind comprising slats having at least one small hole adjacent one edge of each slat. This kind of blind comprises technical features as described in the preamble of independent claim 1.
  • the invention offers a slender rope for connecting each slat, each ladder and each lift cord for preventing the slats to slide out of one side of a blind, and thus beefing up effects of shutting out light completely.
  • the characteristics of the invention are slats, lift cords, ladders and connectors.
  • the slats are horizontally positioned to space apart in parallel between the two vertical portions of the ladders and respectively on rungs of the ladders.
  • the lift cords are respectively positioned at two opposite sides and near the ladders, Then each slat is provided with at least a hole corresponding to each relative rung of the ladders, and each flexible connector passes through the hole of each slat and then combined with each lift cord and the vertical portion of each ladder so that the side edge of each slat can be prevented from moving laterally and excessively by mutual interaction with the lift cords or the ladders.
  • the method for a blind in the invention includes several steps of inserting a connector through the hole of each slat, of combining a first end of each connector with the vertical portion of each ladder, and of combining the second end of each connector with each lift cord.
  • the slats are prevented from sliding out of either side of the blind, and in addition, the holes of the slats may be hidden by the overlapped portions of every two adjacent slats in case the blind is handled to close up a gap between every two adjacent slats, whether the slats may be turned clockwise or counterclockwise.
  • a first embodiment of a blind in the present invention includes a headrail 10, a bottomrail 20, two ladders 30, a plurality of slats 40, two lift cords 50 and a plurality of connectors 60 as main components assembled together.
  • the two ladders 30 extend down in parallel from the headrail 10 to the bottomrail 20, positioned in a front portion of the blind, and respectively having two vertical portions 31 near the rear side of the blind and a plurality of rungs 32 connected and spaced apart equidistantly between the two vertical portions 31
  • the slats 40 are disposed horizontally below the headrail 10 and above the bottomrail 20 in the parallel condition and respectively lie nearly on the rungs 32 of the ladders 30.
  • the rungs 32 may be turned around to let the slats 40 to incline in an angle, limited by the rungs 32 in their slanting movement as shown in Fig. 4 .
  • each slat 40 is bored with a hole 41 respectively near a rear longitudinal side edge and spaced apart.
  • the two lift cords 50 extend down in parallel from the headrail 10, having their lower end connected with the bottomrail 20.
  • the connectors 60 are very flexible, respectively having a first end 61 connected to the vertical portion 31 of the ladder 30 and distanced a little from the relative rung 32 and passing through the hole 41 of the relative slat 40, and a second end positioned under the relative slat 40 and then connected to a proper point of the lift cord 50.
  • the second end 62 is a looped end 62 for the lift cord 50 to pass through and move up and down therein
  • method for the blind in the invention includes following steps.
  • each connector 60 located between the ladder 30 and the hole 41 of each slat 40 can block each slat 40 from sliding out of the blind.
  • Such a design of the looped ends 62 of the connectors 60 can permit up-and-down movement of the lift cords 50 but inhibit their right-and-left movement.
  • the holes 41 of the slats 40 planned in the invention is located near the longitudinal side edge, and in addition, the distance (d2) between each hole 41 and the longitudinal side edge is shorter than the width (d3) of the overlapped portions of the two vertically adjacent slats 40, so when all the slats 40 are turned to shut completely, each hole 41 can be hidden by the relative overlapped portions of the two adjacent slats 40, which can effectively shut off light from passing through the blind.
  • the distance (d1) between the first end 61 of each connector 60 and the relative rung 32 of the ladder 30 is longer than the distance (d2) between the hole 41 and the longitudinal side edge of the slat 40 so that each connector 60 and the ladder 30 can freely move relatively, permitting all the slats 40 move smoothly without any hitch.
  • a manufacturer can select properly slender cotton cords or plastic cords for the connectors 60, so every two adjacent slats can be positioned nearer to overlap so that the gap between every two adjacent slats may be lessened as possible in case of closing the blind.
  • each connector 60 and the lift cords 50 are positioned in the rear portion of the blind in the preferred embodiment, the end of each connector 60 is also possible to be combined with the lift cord 50 (not shown in figures) in the front portion of the blind, as an equal art.
  • Fig 5 shows a second embodiment of a blind in the invention, which has almost the same structure as the first one, except that the connectors 60 are respectively composed of two ropes, passing through the holes 41 and having the second end forming a knot 63 so that the lift cord 50 can pass though between the two ropes.
  • each connector 60 and the ladder 30 As for the connecting way of the first end 61 of each connector 60 and the ladder 30, a weaving way or mechanical sawing can directly be used or any way fastening the both together can be employed, as an equal art.
  • ears added to the longitudinal side edge of each slat 40 can be used in place of the holes 41.
  • Fig. 6 shows a third embodiment of a blind in the invention, which has almost the same structure, except that the second end 62 of each connector 60 is added with a metal element 64 having an outer diameter larger than the inner diameter of the hole 41 to let each slat 40 stop the metal element 64 and the connector 60 together. Therefore the second end 62 is unable to slide out of the slat 40.
  • a loop or a knot shown in Fig. 5 also can be used for hampering the connector 60 from loosening off.
  • a plurality of sleeving members 70 can further be affixed on the ladders 30, and its number can be more or less than that of the rungs 32 of the ladders 30.
  • the sleeving members 70 can be located at the front end and the rear end of each rung 32 or only the rear end of each rung 32.
  • An inner end 71 of each sleeving member 70 is connected with the vertical portion 31 and an outer looped end 72 is for the lift cord 50 to pass through.
  • the ladders 30 are connected to each slat 40 by means of the connector 60 and the ladder 30 is combined with the lift cord 50 by means of the sleeving member 70 so that the ladder 30, the connector 60 and the lift cord 50 can keep the slat 40 from sliding out of the blind and the lift cord 50 from moving laterally.
  • Fig. 7 shows a fourth embodiment of a blind in the invention, which has almost the same structure as the first one, except that each ladder 30 is connected with each slat 40 on each rung 32 of the ladder 30 by means of the connectors 60 in the same way illustrated in Fig. 6 .
  • each lift cord 50 intertwines intermittently around the vertical portion 31 of each ladder 30 and also passing through a space between every two adjacent rungs 32 from the headrail 10 vertically down to the bottomrail 20, combining effectively each ladder 30 with each lift cord 50.
  • Fig. 8 shows a second style of slats 40 usable in all the preferred embodiments of a blind described above, which is provided with two same holes 41 as that in the above-mentioned embodiments, and a slender groove 42 additionally connected to each hole 41 and opening out of the longitudinal side edge of each slat 40. Then the slender grooves 42 are helpful for the slat 40 to be combined with the ladder 30.
  • Fig. 9 shows a third style of slats 40 usable in all the preferred embodiments of a blind in the invention, which is added with a surrounding cover 43 around each original slat 40 as that used in the first embodiment of a blind, giving an alter to its appearance.
  • the cover 43 may be a cloth or a coated layer of paint, possible to permit the flexible connector 60 to pass through the cover 43 and the hole 41.
  • the invention has the following advantages, as can be understood from the foresaid description.
