Definitions

  • the present invention relates to a structure for curtain positioning by which the two lateral sides of a curtain are raised/lowered synchronically in equal levels, and especially to a structure for curtain positioning provided for direct pushing/pulling of a user to draw and release the curtain.
  • horizontally raising/lowering curtains such as: horizontal blinds, Roman shades, pleated shades etc.
  • the mode of operation of conventional horizontally raising/lowering curtains is that by which a user can manipulate a manipulating rope and a manipulating rod to indirectly draw, release and adjust the curtain; taking a normal horizontal blind as an example, generally, a manipulating rope is hung there for a user to draw and release the curtain, and a manipulating rod is provided for the user to adjust the angular position against the horizon of the blades of the curtain, in such operations, some complicated pulling and linking up mechanisms (such as the conventional elements including connecting ropes, gearing pulleys, reverse positioning elements etc. which are not necessarily to be described further) are involved, in order to get an effect that the two lateral sides of the curtain are raised/lowered synchronically in equal levels and that the user can adjust the angular position of the curtain.
  • some complicated pulling and linking up mechanisms such as the conventional elements including connecting ropes, gearing pulleys, reverse positioning elements etc. which are not necessarily to be described further
  • the manipulating rope and the manipulating rod can affect the esthetic appearance of the curtain, and even can have a problem of safety of wrapping the neck of a child who is manipulating the rope; for the purpose of keep safety and beautiful appearance of the curtain, the pulling and linking up mechanisms in relating to operating of the manipulating rope and rod must be hidden.
  • the pulling and linking up mechanisms are hidden in a positioning frame provided on the top end of the curtain; and by the problems of being unfavorable for having beautiful appearance and for utilization of space, and that the space inside of the positioning frame for receiving the pulling and linking up mechanisms is small, related assembling and maintenance are quite difficult.
  • the primary object of the present invention is to provide a structure for curtain positioning by which the two lateral sides of a curtain are raised/lowered synchronically in equal levels, the structure needs not to be provided with the manipulating rope and the manipulating rod mentioned in the "mode of operation of conventional horizontally raising/lowering curtains" stated above, and can allow a user to directly push and pull to draw and release for adjusting the curtain such as a horizontal blind, Roman shade, pleated shade etc. of which the two lateral sides of the curtain require to be raised/lowered synchronically in equal levels.
  • the curtain such as a horizontal blind
  • the curtain can be pushed and pulled slightly to adjust the angular position against the horizon of the blades of the curtain.
  • the structure for curtain positioning of the present invention comprises: a positioning frame; at least two positioning rope sets extending downwards from the positioning frame for positioning of corresponding parts of the curtain; a rotating axle horizontally provided in the positioning frame; at least two reel sets synchronically moving with the rotating axle, each reel set includes at least a reel linking up with the rotating axle, a drawing rope of which one end is reeled up on the reel and the other end is used to draw and release the curtain; and a positioning control box provided in the positioning frame, the positioning control box has therein at least a bush as a follower member of and for extending therethrough of the rotating axle, a first cogged winch linking up with the bush, a second cogged winch linking up with the first cogged winch, a resisting reed having an end reeled on the first cogged winch and having the other end engaged on the second cogged winch; the first cogged winch is provided thereon with a first bevel gear synchronically rotated with the first cogged winch, and the bush is provided there
  • the positioning control box provides a resisting force to prevent the curtain from dropping by its own gravity, surely the resisting force provided by the positioning control box is not necessarily completely accurately identical to the gravity of the curtain, it is only necessary that the difference between the resisting force and the gravity of the curtain is smaller than the natural resisting forces created in the structure for curtain positioning (such as: the maximum stationary friction of the structure for curtain positioning itself and among the members in the structure for curtain positioning); thereby, when a user directly pushes and pulls the curtain, he can draw and release for adjusting the curtain, he needs not to use some other indirect way to adjust the curtain; when the user stops pushing and pull ing the curtain, the curtain can be kept immediately at the position when he stops.
  • each drawing rope can be extended downwards from above through each elongate strip and connected to the bottommost elongate strip; each reel is provided with a synchronous pulley; and each positioning rope set at least includes a main positioning cable of which the top is hung on the synchronous pulley and of which two ends pend parallely to each other, and includes a plurality of transverse cables provided between the two ends pending parallely to each other of the main positioning cable for mounting the elongate strips; the area between the main positioning cable and the synchronous pulley is in the state of having a slight frictional impedance, that is a non-tightly matching state.
  • the rotating axle will synchronically linking up with the reel sets to synchronically reel in/off the drawing ropes; at this time, the main positioning cable on the top of each of the positioning rope sets is moved by the synchronous pulley to render the transverse cables 22 and the elongate strips 101 mounted on the transverse cables 22 to get change in inclination degree; when the transverse cables are inclined to make the elongate strips engage with one another, by virtue that the area between the main positioning cable and the synchronous pulley is in the state of having a slight frictional impedance-that is a non-tightly matching state, the synchronous pulley can still rotate in an idle mode without hindering operation of the reels; in other words, the user can adjust the angular position against the horizon of the blades of the curtain.
  • the present invention at least has the following advantages:
  • Figs. 1 and 2 are respectively a schematic view showing the appearance of the most preferred embodiment of the present invention and a perspective view showing the appearance of a positioning control box 50 and a reel set 40 of the most preferred embodiment of the present invention
  • the structure for curtain positioning of the present invention comprises: a positioning frame 10; at least two positioning rope sets 20, a rotating axle 30, at least two reel sets 40 and the positioning control box 50; a curtain 100 in this embodiment is depicted as a horizontal blind for the convenience of specification, the curtain 100 is composed of multiple elongate strips 101 which are arranged from the uppermost one to the lowermost one all in horizontal disposition.
  • the positioning frame 10 is provided above the curtain 100 for directly or indirectly positioning of the curtain 100 for the convenience of providing of the curtain 100 at a window, on a wall or some other structure; the positioning frame 10 has therein a receiving space for receiving the rotating axle 30, the reel sets 40 and the positioning control box 50.
  • each positioning rope set 20 is extended downwards from the positioning frame 10 for positioning of corresponding parts of the curtain 100; each positioning rope set 20 at least includes a main positioning cable 21 of which two ends pend parallely to each other, and includes a plurality of transverse cables 22 provided between the two ends pending parallely to each other of the main positioning cable 21 for mounting the elongate strips 101.
  • the rotating axle 30 is provided in the positioning frame 10 horizontally, for instance, it is provided in the positioning frame 10 horizontally by means of the reel sets 40 and the positioning control box 50.
  • each reel set 40 includes at least a reel 41 linking up with the rotating axle 30, a drawing rope 42 of which one end is reeled up on the reel 41 and the other end is used to draw the and release the curtain 100; the drawing rope 42 can be extended downwards from above through each elongate strip 101 and connected to the bottommost elongate strip 101.
  • Each reel 41 is provided with a synchronous pulley 43 for hanging thereon of the top of the main positioning cable 21 of a positioning rope set 20; the main positioning cable 21 and the synchronous pulley 43 mutually are in a non-tightly matching state.
  • the positioning control box 50 is provided in the positioning frame 10 for extending therethrough of the rotating axle 30 to provide a suitable resisting force to resist rotation of the rotating axle 30.
  • Fig. 3 is an anatomic perspective view of the positioning control box 50 of the most preferred embodiment of the present invention
  • the positioning control box 50 is provided in its box body 51 at least with a bush 52 as a follower member of and for extending therethrough of the rotating axle 30, a first cogged winch 53 linking up with the bush 52, a second cogged winch 54 linking up with the first cogged winch, and a resisting reed 55 having an end reeled on the first cogged winch 53 and having the other end engaged on the second cogged winch 54;
  • the first cogged winch 53 is provided thereon with a first bevel gear 531 synchronically rotated with the first cogged winch 53
  • the bush 52 is provided thereon wi th a second bevel gear 521 in cooperation wi th the first bevel gear 531.
  • the positioning control box 50 provides a resisting force to prevent the curtain 100 from dropping by its own gravity; when a user directly pushes and pulls the curtain 100, he can draw and release for adjusting the curtain 100, he needs not to use some other indirect way to adjust the curtain 100; when the user stops pushing and pulling the curtain 100, the curtain 100 can be kept immediately at the position when he stops.
  • the curtain 100 depicted in the drawings is a horizontal blind for the convenience of specification, in practicing, the curtain 100 can be one of those including Roman shades, pleated shades etc. that have the characteristic of raising/lowering in keeping their horizontal position.
  • Fig. 4 is a schematic view showing an angular position against the horizon of the blades of the curtain 100 of the most preferred embodiment of the present invention
  • the positioning rope sets 40 will also be moved synchronously by linking up of the rotating axle 30; by virtue that the area between the main positioning cable 21 on the top of the positioning rope sets 20 and the synchronous pulley 43 is in the state of having a slight frictional impedance, the main positioning cable 21 will be moved by the main positioning cable 21 to render the transverse cables 22 and the elongate strips 101 mounted on the transverse cables 22 to get change in inclination degree.
  • Fig. 5 is another schematic view showing the angular position against the horizon of the blades of the curtain 100 of the most preferred embodiment of the present invention
  • the positioning rope sets 40 are allowed to be manipulated for reeling in by means of the rotating axle 30 by virtue that the weight of the curtain 100 is not balanced by the resisting force of the positioning control box 50 now; at this time, the direction of rotating of the synchronous pulley 43 is contrary to that shown in Fig.
  • the transverse cables 22 and the elongate strips 101 mounted on the transverse cables 22 get change in inclination degree in the direction contrary to the original one.
  • the user can slightly push and pull the curtain 100 to adjust the angular position against the horizon of the blades of the curtain 100.
  • Fig. 6 is a further schematic view showing the angular position against the horizon of the blades of the curtain 100 of the most preferred embodiment of the present invention, by virtue that the area between the main positioning cable 21 and the synchronous pulley 43 is in the state of having a slight frictional impedance - that is a non-tightly matching state, when the transverse cables 22 are inclined to make the elongate strips 101 engage with one another, the synchronous pulley 43 can still rotate in an idle mode without hindering operation of the reels 40.
  • each positioning rope set 20 is integrally formed with a corresponding one of the positioning rope sets 20; however, in practicing, for the convenience of producing, each positioning rope set 20 can be reformed from a conventional rope ladder; as shown in Fig. 7 , the conventional rope ladder includes a main positioning cable 21 pending vertically and a plurality of transverse cables 22 provided between two side sections of the main positioning cable 21, the two side sections of the main positioning cable 21 are connected with each other (for instance connected by sewing or by means of a connecting element 23), namely, the two side sections of the main positioning cable 21 are integrally connected with each other at the middle top of them to form a circle matching with the synchronous pulley 43.
  • the topmost transverse cable 22 can be regarded as the connecting element 23 between the two side sections of the main positioning cable 21 (not shown), thus the top of the main positioning cable 21 can form a circle matching with the synchronous pulley 43.
