Definitions

  • the present invention relates to a roll-blind (roller blind).
  • a roll-blind is so constructed that it is opened or closed by winding up a blind cloth onto a winding roll or unwinding the blind cloth from the winding roll.
  • the conventional roll-blind employs a coil spring which is contained in the winding roll to continuously apply elastic force to said winding roll to rotate it in the cloth winding-up direction.
  • a coil spring which is contained in the winding roll to continuously apply elastic force to said winding roll to rotate it in the cloth winding-up direction.
  • DE-U-7327616 discloses a stopper mechanism for roller shutters, by means of which the tube on which the roller shutter is wound up is kept at a specific angular position against strains acting from the outside in both directions of rotation.
  • the stopper mechanism according to DE-U-7327616 comprises an operating device. When the operating device is out of operation, the coil spring controlling the tube is locked on a friction ring by means of a driving bush and a rotating ring with stop faces, and in this way the tube is fixed; when the operating device is actuated, the coil spring is released and transmits a rotation movement to the tube.
  • FR-A-1208097 also discloses a stopper mechanism for roller shutters or roll-blinds controlled by a spring, which mechanism comprises a stopper by means of which the mechanism is to be blocked up in both directions when the action of a force changes its direction.
  • the elastic force of the coil spring in the known roll-blinds is excessively strong, the blind cloth is wound up suddenly, so that the blind cloth cannot be regularly wound up onto the winding roll and in some circumstances the blind cloth may become damaged.
  • the elastic force of the coil spring in the known roll-blinds is excessively small, the blind cloth cannot be fully wound up onto the winding roll, that is, the complete operation of the blind cannot be assured.
  • the present invention is characterised by the features of the claims.
  • Fig. 1 illustrates the exterior view of the roll-blind.
  • Fig. 1, 1 is a blind cloth
  • 2 and 3 are brackets for mounting the roll-blind on a window frame orthe like
  • 4 is a grip portion which is gripped by a hand of an operator when the blind cloth is lowered
  • 5 is an operating cord which is pulled downward when the blind cloth is to be wound up.
  • Fig. 2 is an elevational view, partly broken, of the main part of the roll-blind.
  • 6 is a winding roll for winding up the blind cloth 1
  • 7 is a coil spring contained in said winding roll which constantly acts to rotate said winding roll in the cloth winding up direction
  • 8 and 9 are center shafts of said roll.
  • 10 designates a stopper which is arranged on said center shaft 9 to stop the rotation of said winding roll 6 in order to stop the blind cloth at a lowered position against the action of said coil spring
  • 11 designates a speed reducing device which serves to reduce the speed of rotation of the winding roll 6 when said stopper 10 is released so that the winding roll 6 is rotated in the cloth winding-up direction under the action of the coil spring.
  • the stopper 10 comprises a clutch spring 12 which is resiliently fastened on the shaft 9 to stop the rotation of said shaft, and the operating cord 5 is connected to the free end of said clutch spring, so that the clutch spring can be released by pulling said operating cord 5 in the downward direction.
  • the speed reducing gear 11 comprises a flywheel 14 mounted on a shaft 13 and a gear train including gears 15 and 16 which connects said shaft 13 with the shaft 9.
  • the flywheel 14 has a leaf spring 17 fixed in the inside thereof and said leaf spring 17 has an L-shaped projection 17a at its end which is adapted to engage in a notch 18 formed on said shaft 13.
  • the leaf spring 17 including the projection 17a and the shaft 13 including the notch 18 are so arranged that the flywheel 14 is rotated when the shaft 13 is rotated in the counterclockwise direction indicated by an arrow A in Fig. 3, that is, in the direction of winding up the blind cloth onto the winding roll 6.
  • the grip portion 4 When it is desired to lower the blind cloth 1, the grip portion 4 is gripped and pulled in the downward direction. The winding roll 6 is rotated thereby, and the rotation of this winding roll 6 serves to energize the coil spring 7 contained in the winding roll 6. When the blind cloth is lowered to a desired position and the pulling operation of the grip portion 4 is stopped, the blind cloth is held at the desired lowered position because the rotation of the shaft 9 of the winding roll 6 in the opposite direction is arrested by the clutch spring 12.
  • the operating cord 5 attached to the end of the clutch spring 12 is pulled in the downward direction. Then the clutch spring 12 is loosened on the shaft 9, so that the stopper is released and the winding roll 6 is rotated under the action of the coil spring 7, thereby winding up the blind cloth 1 thereon.
  • the blind cloth can be stopped at any desired position and furthermore smooth winding-up operation of the blind cloth is produced while the resilient force of the coil spring is effectively utilized, because of including the flywheel which acts to produce smooth rotation of the winding roll. Furthermore, at the time of lowering the blind cloth, the blind cloth can be operated by applying relatively small force to pull the blind cloth in the downward direction, since the flywheel is isolated from the winding roll during lowering of the blind cloth.
  • Figs. 5, 6 and 7 illustrate the second embodiment of the present invention.
  • the parts the same as those shown in Fig. 2 are indicated by the same reference numerals and the detailed explanation thereof is omitted.
  • Figs. 5 and 6 show a speed reducing device consisting of a balance wheel mechanism 27 which is connected to one of the shafts of the winding roll 6 driven by the resilient force of the coil spring 7 and which acts to hold the rotation of said winding roll at a low and constant speed.
  • the winding roll 6 is formed at its one end 21 with a slit 22, in which is engaged one end 24a of a one-way clutch spring 24 wound on a shaft 23 of said winding roll.
  • the shaft 23 is connected through a gear train 20 with the balance wheel mechanism 27 which constitutes the speed reducing device, and the rotation of this shaft is normally arrested by a stopper 26.
  • the one-way clutch spring 24 which is arranged between the shaft 23 (fixedly connected with the center shaft 25) and the end of the winding roll 6 allows one to pull the blind cloth at high speed in the downward direction, independently of the balance wheel mechanism 27 while the blind is lowered.
  • the balance wheel mechanism 27 comprises a ratchet wheel 28 and a pawl member 29 which is supported at its center by a pivot axis 30 for rocking movement therearound and is adapted to alternately engage at its opposite ends with the teeth of said ratchet wheel.
  • the stopper 26 comprises a pawl lifting member 31 which is arranged at one end of said pawl member 29 to upwardly urge said end of the pawl member 20 to stop the rocking movement thereof.
  • Said pawl lifting member 31 is normally biased in the upward direction under the action of a coil spring 32 and can be lowered against the action of said coil spring by pulling an operating cord 5 in the downward direction.
  • the winding roll 6 When the grip portion 4 of the blind cloth is pulled downward, the winding roll 6 is rotated and the blind cloth 1 is lowered.
  • the pawl member 29 of the balance wheel mechanism is held at its one end in engagement with the ratchet wheel 28 by the pawl lifting member 31, so that the balance wheel mechanism is held in inactive state. Since the one-way clutch spring 24 exists between the center shaft 25 and the end of the winding roll 6 (see Fig. 5), the winding roll 6 can rotate, independently of the balance wheel mechanism which is now held in inactive state, so that the blind cloth can be lowered at any desired speed.
  • the pulling of the grip portion 4 of the blind cloth is stopped, whereby the winding roll 6 becomes fixedly connected with the shaft 25 through the one-way clutch spring 24, and thus the blind cloth becomes held at this position.
  • the operating cord 5 When it is desired to raise the blind, the operating cord 5 is pulled downward. Then, the lifting member 31 is lowered against the action of the coil spring 32, thereby releasing the pawl member 29. Accordingly, the winding roll 6 starts its rotation in the cloth winding-up direction. At the same time, the ratchet wheel 28 starts its stepwise rotating movement with the rocking movement of the pawl member 29, and thus the winding roll 6 rotates at a constant and low speed in the cloth winding-up direction, thereby smoothly raising the blind cloth.
  • the rocking movement of the pawl member 29 is stopped at once and thus the blind cloth is stopped at the desired position.
  • Figs. 5-7 shows a construction of the roll-blind which includes means for storing the resilient force of the coil spring 7 in order to allow the smooth upward movement of the blind cloth, wherein the means for storing the resilient force of the coil spring consists of the balance wheel mechanism connected to the center shaft of the cloth winding roll, whereby the winding-up operation of the blind cloth can be effected at a constant and low speed and the blind cloth can be stopped at any desired position by stopping the operation of said balance wheel mechanism by pulling the operating cord downward.
  • this construction allows one to lower the blind cloth to any desired position at high speed because the one-way clutch spring acts to cut off the balance wheel mechanism from the winding roll and consequently the blind cloth can be lowered indepen- dentl y of the balance wheel mechanism during the cloth lowering operation.
  • Figs. 8,9 and 10 illustrate a modified form of the stopper mechanism.
  • the roll-blind shown in Figs. 8, 9 and 10 includes a speed reducing device 27 and a flywheel 14 which are arranged to produce the rotation of the winding roll 6 at a smooth and constant speed during the cloth winding-up operation.
  • a ratchet mechanism 33 is included in a gear 27a of the speed reducing device 27, and the speed reducing device 27 and the flywheel 14 are so arranged that they are effective only during the blind winding-up operation.
  • the stopper mechanism includes a clutch shaft 34, a spring clutch 35 wound on said shaft and a clutch ring 36 arranged on said spring clutch.
  • the spring clutch 35 is formed at its opposite ends with projections 35a and 35b, which are arranged to come into engagement with a pin 37 which projects inwardly of the case.
  • the clutch ring 36 has a stop portion 36a formed on the outside thereof, and a stopper member 38 is arranged around the clutch ring 36 so that it can come into engagement with said stop portion 36a to stop the rotation of said clutch ring in the cloth winding-up direction.
  • the stopper member 38 is pivotally mounted on a pivot axis 39 in the case and it has a forward end 38a which is arranged to engage with the step portion 36a and another end 38b to which the operating cord 5 is connected.
  • a coil spring 40 is arranged between the end 38b of the stopper member 38 and the case in order to normally rotate said stopper member 38 into engagement with the step portion 36a to stop the rotation of the clutch ring 36 in the cloth winding-up direction.
  • the clutch device including the clutch shaft 34, the spring clutch 35 and the clutch ring 36 functions to loosen the clutch spring 35 to allow free rotation of the clutch shaft 34 during the blind cloth 1 is pulled downward, to tighten said spring clutch 35 when the clutch ring 36 is stopped by the stopper member 38, and to loosen said spring clutch 35 to allow rotation of the clutch shaft 34 in the cloth winding-up direction when the stopper member 38 is released from the step portion to allow rotation of the clutch ring 36.
  • Fig. 10(a) shows the state of roll-blind where the blind cloth 1 is completely wound up onto the winding roll.
  • the clutch shaft 34 is rotated together with the rotation of the winding roll 6 in the counterclockwise direction in Fig. 10(a).
  • the projection 35a of the spring clutch 35 wound around the shaft 34 comes into engagement with the pin 37 and then the spring clutch 35 is loosened to allow free rotation of the shaft 34 so that the blind cloth 1 can be lowered.
  • the blind cloth 1 is lowered to any desired position and the lowering of the cloth is stopped, the blind cloth tends to be wound up onto the winding roll under the action of the coil spring 7.
  • step portion 36a of the clutch ring 36 comes into engagement with the end 38a of the stopper member 38 and the pin 37 cannot push the projection 35a of the spring clutch 35 any more, so that the spring clutch becomes effective. Under such conditions, the blind cloth 1 is stopped at the desired position, as shown in Fi g . 10(b).
  • the winding roll is rotated at a constant and stable speed during the blind winding-up operation, even if there are variations in width and height of the roll-blind and at the time of cloth winding operation the blind cloth can be raised to its completely wound up position only by releasing the stopper member at the start of the operation.
  • Figs. 11-15 illustrate a blind mounting device which is effectively used to mount the roll-blind as explained above on a window frame, wall or the like. This device allows one to fixedly mount the blind at any desired position very easily, without requiring complicated and troublesome operations as required in the conventional mounting method.
  • the blind mounting device includes a base plate 43 on which the blind 41 is mounted by means of two brackets 42 which are fixed on said base plate 43 at a predetermined distance from each other.
  • the blind mounting device further includes two supporting members 46, each of which includes a hook member 44 having hooks 44a and 44b at its upper and lower edges and a supporting plate 45 connected with said hook member 44, and these supporting members 46 are fixed on the window frame, wall surface or other surface on which the blind is to be mounted, at a suitable distance from each other.
  • Said base plate 43 having the blind previously mounted thereon is connected onto said supporting members 46 by bringing the upper and lower edges of said base plate 43 into engagement with the hooks 44a and 44b of said hook members 44 of said supporting members 46 and then fixedly connecting said base plate 43 with said hook members by means of fastening elements such as screws 47, whereby the blind 41 is mounted on the window frame, wall surface or the like.
  • the base plate 43 is formed at its upper and lower edges with hook portions 43a and 43b, respectively, which are brought into engagement with the hooks 44a and 44b of the hook member 44, and the screw 47 is threaded into the lower hook 44b of the hook member 44 to fix the lower hook portion 43b of the base plate 43 in said lower hook 44b, thereby fixing the base plate 43 by the supporting member 46.
  • the supporting member 46 (Fig. 15) consists of an L-shaped supporting plate 45 and a hook member 44 which is rotatably mounted on the center of one leg 45a of said L-shaped plate by means of a pivot.
  • Fig. 13 shows the device according to the present invention in a state where the base plate 43 is mounted on the supporting members 46, 46.
  • the base plate 43 is engaged in the hook members 44 on the supporting plates 45 and locked thereto by the screws 47 which are threaded into the lower hooks 44b of the hook members 44 and pressed against the hook portions 43b of the base plate 43.
  • a roll-blind When a roll-blind is mounted on a wall surface by this mounting device, firstly a plurality of the supporting members 46, each having the supporting plate 45 and the hook member 44, are attached at a suitable distance on the wall surface at their legs 8a of said supporting plates 45a by means of screws or the like and then the base plate 43 on which the roll-blind has been previously mounted is mounted on said supporting members 46 by bringing the upper and lower hook portions 43a and 43b of said base plate 43 into engagement with the hooks 44a and 44b of said hook members 44.
  • the position of the blind is adjusted by sliding said base plate 43 to the right or left in said supporting members 46, and at a desired position of said blind the screws 47 are tightened to fix the blind at the desired position.
  • Fig. 14 shows the roll-blind mounted on the ceiling surface by this mounting device.
  • the supporting members 46 are fixed at the legs 45a of the supporting plates 45 on the ceiling surface by means of screws or the like, and the blind is supported by these supporting members.
