Definitions
- the invention relates to a screen-positioning device for use in a roll blind of the type defined in the preamble of Claim 1.
- the device as disclosed by JP Y 58-21919 allows the spring-motor to roll up the screen to a predetermined height and stop the same without shock when the screen is released. It comprises a screw-bolt coaxially connected to the free end of the fixed shaft, a screw-nut mounted on the screw-bolt for rotation with the screen-roll, and a stopper attached to the screw-bolt to prevent a further axial movement of the screw-nut toward the stopper or rotation of the screen-roll.
- the stopper is composed of a first disc secured to the screw-bolt, a second disc axially movably but non-rotatably mounted on the screw-bolt to catch the screw-nut, and a plurality of belleville springs interposed between the first and second discs.
- the known device has disadvantages one of which is that the screen is somewhat heavy to be lowered from the roll-up height. The reason for this is that the second non-rotatable disc frictionally resists the rotation of the screw-nut when the screen is lowered.
- Another disadvantage is that it is not easy to adjust the axial position of the screw-nut or roll-up height of the screen, because the screw-nut can not be adjusted unless the screen-roll is removed from the brackets. In the case of a plurality of parallel roll blinds, it is impossible to raise all the screen-ends in a line without many trials each needing removal of the screen-roll from the brackets.
- the invention as claimed is intended to provide a remedy by virtue of the features of the characterising portion of claim 1.
- the torsional spring When the torsional spring is frictionally engaged with the screw-nut, it is so twisted as to prevent a further rotation of the screw-nut without bringing any shock and have a spring-back force to rotate the screw-nut or screen-roll in the direction in which the screen is lowered. Therefore, it is very smooth to lower the screen from the roll-up position.
- the fixed shaft is supported by a bracket with the intervention of a mechanism comprising a dial-ring coaxially fitted on a sector, a brake drum secured to said bracket and coaxially contained within said sector, and a coil spring fitted on said brake drum, said dial-ring having an inner projection disposed between the both ends of said coil spring in a slit which is formed in the sector.
- the advantages offered by the invention are mainly that the screen is lightly lowered from its roll-up position.
- the roll-up height of screen is exactly adjusted by fingering the dial-ring while the screen-roll is kept supported by the brackets.
- Each trial of pulling and releasing the screen for an adjustment of the roll-up height needs no removal of the screen-roll from the brackets, so that it is very quick and easy to adjust the roll-up height of the screen.
- the figures show one end portion of a roll blind equipped with the device according to the invention.
- a screen-roll 10 has one end portion rotatably supported by a fixed shaft 20 passing through the end cap 14 of the screen-roll.
- the fixed shaft 20 has its outer end fixedly sustained by a bracket 12 and the other end pinned to an extension shaft 21, which is composed of an outer drum portion 22, an intermediate screw-bolt portion 23 and an inner end portion 24.
- a non-illustrated spring-motor is interposed between the opposite fixed shaft (not shown) and the screen-roll 10 to rotate the screen-roll 10 in the direction in which the screen 30 is rolled up.
- the drum portion 22 is slightly tapered toward the screw-bolt portion 23 and coupled with a torsion spring 25 in the form of a coil which has an end secured to the drum portion 22 and the other free end loosely turning around the screw-bolt portion 23.
- a screw-nut 26 is screwed on the screw-bolt portion 23 and circumferentially formed with splines 27 which are coupled with axial projections 16 on the inner circumference of the screen-roll 10. This means that the screw-nut 26 moves back and forth along the screw-bolt portion 23 as the screen-roll 10 rotates to wind up and down the screen 30.
- the inner end portion 24 is rotatably supported by a rotary collar 29, which is peripherally splined to couple with the axial projection 16 for rotation with the screen-roll 10.
- the screw-nut 26 has a conical surface 28 for fitting engagement with the spring 25, the inner diameter of which is larger than the minimum diameter of the conical surface 28 but smaller than the maximum diameter thereof.
- the conical surface 28 is so engaged with the free end portion of the spring 25 that the spring 25 is caused to tighten on the drum portion 22.
- the spring 25 allows no further rotation of the screw-nut 26 as well as the screen-roll 10 and absorbs a shock when the screen 30 stops at the height.
- the inventive device allows the screen to be lightly lowered because the screw-nut always receives a spring-back force to rotate the screen-roll in the direction in which the screen is lowered whenever it is engaged with the stopper in the form of a torsional spring.
- the roll blind is provided with the screen-roll 10 one end portion of which is rotatably fitted on a cylindrical portion of the fixed shaft 20.
- the fixed shaft has an angular portion 20a fitted in an angular bore of a collar 32, which is secured to a sector 34 by set screws.
- the sector 34 coaxially contains a brake coil spring 36 around a brake drum 38.
- the brake drum 38 is rivetted to a bracket 50, which is fixed to a ceiling or the like by set screws.
- a dial-ring 40 is somewhat loosely fitted on the sector 34.
- the sector 34 has its periphery partly cut off as a slit 35 into which the opposite ends 36a, 36b of the brake coil spring 36 are inserted.
- the both ends 36a, 36b are not crossed but open when axially viewed.
- the dial-ring 40 has an inner projection 41 put in a space between the both ends 36a, 36b.
- the collar 32 is fitted on the angular portion 20a of the fixed shaft and rotatably contained within the brake drum 38.
- a snap ring 33 is mounted within the brake drum 38 to prevent the collar 32 from slipping out of the brake drum 38.
- the collar 32 is fixed to the sector 34 by set screws so that the sector 34 is also prevented from axially slipping out of the the brake drum 38 and always kept on the outer periphery of the brake coil spring 36.
- the inner projection 41 pushes one of the ends 36a, 36b in the direction in which the brake coil spring 36 is loosened to rotate together with the dial-ring 40 and then cause the sector 34 or fixed shaft 20 to turn.
- the fixed shaft 20 can not cause the dial-ring 40 to rotate, because the fixed shaft 20 or sector 34 always pushes the end in the counter direction in which the brake coil spring 36 is tightened on the brake drum 38 to stop the rotation of the sector 34 or fixed shaft 20.
- the fixed shaft 20, passing through the end cap 14 of the screen-roll 10, is pinned to an extension shaft 21, which has a drum portion 22, a screw-bolt portion 23 and an end portion 24.

- the inner diameter of the coiled spring 25 is larger than the minimum diameter of the conical surface 28 but smaller than the maximum diameter of the same.
- the screw-nut 26 When the screen-roll 10 winds up the screen 30 to a predetermined height, the screw-nut 26 has its conical surface 28 engaged with the free end of the coil spring 25 in a manner that the conical surface 28 rotates the coil spring 25 to tighten on the brake drum 22.
- the coil spring 25 allows no further rotation of the screw-nut 26 or screen-roll 10 to stop the screen 30 at the predetermined height.

Abstract
Description
- The invention relates to a screen-positioning device for use in a roll blind of the type defined in the preamble of Claim 1.
- The device as disclosed by JP Y 58-21919 allows the spring-motor to roll up the screen to a predetermined height and stop the same without shock when the screen is released. It comprises a screw-bolt coaxially connected to the free end of the fixed shaft, a screw-nut mounted on the screw-bolt for rotation with the screen-roll, and a stopper attached to the screw-bolt to prevent a further axial movement of the screw-nut toward the stopper or rotation of the screen-roll. The stopper is composed of a first disc secured to the screw-bolt, a second disc axially movably but non-rotatably mounted on the screw-bolt to catch the screw-nut, and a plurality of belleville springs interposed between the first and second discs.
- The known device has disadvantages one of which is that the screen is somewhat heavy to be lowered from the roll-up height. The reason for this is that the second non-rotatable disc frictionally resists the rotation of the screw-nut when the screen is lowered.
- Another disadvantage is that it is not easy to adjust the axial position of the screw-nut or roll-up height of the screen, because the screw-nut can not be adjusted unless the screen-roll is removed from the brackets. In the case of a plurality of parallel roll blinds, it is impossible to raise all the screen-ends in a line without many trials each needing removal of the screen-roll from the brackets.
- The invention as claimed is intended to provide a remedy by virtue of the features of the characterising portion of claim 1. When the torsional spring is frictionally engaged with the screw-nut, it is so twisted as to prevent a further rotation of the screw-nut without bringing any shock and have a spring-back force to rotate the screw-nut or screen-roll in the direction in which the screen is lowered. Therefore, it is very smooth to lower the screen from the roll-up position.
- In preference, the fixed shaft is supported by a bracket with the intervention of a mechanism comprising a dial-ring coaxially fitted on a sector, a brake drum secured to said bracket and coaxially contained within said sector, and a coil spring fitted on said brake drum, said dial-ring having an inner projection disposed between the both ends of said coil spring in a slit which is formed in the sector. Whenever the sector is rotated by the extension shaft or fixed shaft, the inner projection pushes one of the both ends of the coil spring in the direction in which the spring tightens on the brake drum, resulting in that the sector can not rotate. On the other hand, whenever the sector is rotated by the dial-ring, the inner projection pushes the end of the brake coil spring in the direction in which the spring loosens from the brake drum with the result that the dial-ring can rotate the sector as well as the screw-bolt. Upon rotation of the dial-ring, the screw-bolt portion rotates in either direction. This means that the axial position of the screw-nut is exactly adjusted by rotating the dial-ring. The dial-ring is easily rotated by fingers while the screen-roll remains supported by the both brackets.
- The advantages offered by the invention are mainly that the screen is lightly lowered from its roll-up position. The roll-up height of screen is exactly adjusted by fingering the dial-ring while the screen-roll is kept supported by the brackets. Each trial of pulling and releasing the screen for an adjustment of the roll-up height needs no removal of the screen-roll from the brackets, so that it is very quick and easy to adjust the roll-up height of the screen. It is easy to adjust a plurality of parallel blinds in a manner that all the screen-ends are levelled.
- One way of carrying out the invention is described in detail below with reference to drawings which illustrate preferred embodiments, in which:-
- FIG. 1 is a longitudinal section of the relevant portion of a roll blind equipped with the device according to the invention, illustrating the device when the screen is fully pulled down;
- FIG. 2 is a view similar to FIG. 1, illustrating the device when the screen is rolled up to a desired height;
- FIG. 3 is a view of another embodiment, similar to FIG. 1; and
- FIG. 4 is a section taken along the line IV-IV of FIG. 3.
- The figures show one end portion of a roll blind equipped with the device according to the invention.
- As seen in FIG. 1, a screen-
roll 10 has one end portion rotatably supported by afixed shaft 20 passing through theend cap 14 of the screen-roll. The fixedshaft 20 has its outer end fixedly sustained by abracket 12 and the other end pinned to anextension shaft 21, which is composed of anouter drum portion 22, an intermediate screw-bolt portion 23 and aninner end portion 24. A non-illustrated spring-motor is interposed between the opposite fixed shaft (not shown) and the screen-roll 10 to rotate the screen-roll 10 in the direction in which thescreen 30 is rolled up. Thedrum portion 22 is slightly tapered toward the screw-bolt portion 23 and coupled with atorsion spring 25 in the form of a coil which has an end secured to thedrum portion 22 and the other free end loosely turning around the screw-bolt portion 23. A screw-nut 26 is screwed on the screw-bolt portion 23 and circumferentially formed withsplines 27 which are coupled withaxial projections 16 on the inner circumference of the screen-roll 10. This means that the screw-nut 26 moves back and forth along the screw-bolt portion 23 as the screen-roll 10 rotates to wind up and down thescreen 30. Theinner end portion 24 is rotatably supported by arotary collar 29, which is peripherally splined to couple with theaxial projection 16 for rotation with the screen-roll 10. The screw-nut 26 has aconical surface 28 for fitting engagement with thespring 25, the inner diameter of which is larger than the minimum diameter of theconical surface 28 but smaller than the maximum diameter thereof. - As seen in FIG. 2, when the screen-
roll 10 is rotated to raise thescreen 30 to a predetermined height, theconical surface 28 is so engaged with the free end portion of thespring 25 that thespring 25 is caused to tighten on thedrum portion 22. Thus, thespring 25 allows no further rotation of the screw-nut 26 as well as the screen-roll 10 and absorbs a shock when thescreen 30 stops at the height. - Whenever the
spring 25 is engaged with the screw-nut 26, it has a spring-back force to rotate the screw-nut 26 or screen-roll 10 in the direction in which thescreen 30 is lowered. This ensures that thescreen 30 is lightly lowered from the roll-up position. - In comparison with the known device in which it is somewhat heavy to lower the screen from the roll-up height because the screw-nut undergoes a frictional resistance whenever it is rotated to separate from the stopper, the inventive device allows the screen to be lightly lowered because the screw-nut always receives a spring-back force to rotate the screen-roll in the direction in which the screen is lowered whenever it is engaged with the stopper in the form of a torsional spring.
- As seen in FIG. 3, the roll blind is provided with the screen-
roll 10 one end portion of which is rotatably fitted on a cylindrical portion of thefixed shaft 20. The fixed shaft has anangular portion 20a fitted in an angular bore of acollar 32, which is secured to asector 34 by set screws. Thesector 34 coaxially contains abrake coil spring 36 around abrake drum 38. Thebrake drum 38 is rivetted to abracket 50, which is fixed to a ceiling or the like by set screws. A dial-ring 40 is somewhat loosely fitted on thesector 34. - As seen in FIG. 4, the
sector 34 has its periphery partly cut off as aslit 35 into which theopposite ends 36a, 36b of thebrake coil spring 36 are inserted. The bothends 36a, 36b are not crossed but open when axially viewed. The dial-ring 40 has aninner projection 41 put in a space between the bothends 36a, 36b. Thecollar 32 is fitted on theangular portion 20a of the fixed shaft and rotatably contained within thebrake drum 38. - As seen in FIG. 3, a
snap ring 33 is mounted within thebrake drum 38 to prevent thecollar 32 from slipping out of thebrake drum 38. Thecollar 32 is fixed to thesector 34 by set screws so that thesector 34 is also prevented from axially slipping out of the thebrake drum 38 and always kept on the outer periphery of thebrake coil spring 36. - As seen in FIG. 3, when the dial-
ring 40 rotates in either direction, theinner projection 41 pushes one of theends 36a, 36b in the direction in which thebrake coil spring 36 is loosened to rotate together with the dial-ring 40 and then cause thesector 34 or fixedshaft 20 to turn. However, thefixed shaft 20 can not cause the dial-ring 40 to rotate, because thefixed shaft 20 orsector 34 always pushes the end in the counter direction in which thebrake coil spring 36 is tightened on thebrake drum 38 to stop the rotation of thesector 34 or fixedshaft 20. - The
fixed shaft 20, passing through theend cap 14 of the screen-roll 10, is pinned to anextension shaft 21, which has adrum portion 22, a screw-bolt portion 23 and anend portion 24. Theend portion 24 is loosely supported by arotary collar 29, which is peripherally coupled with the screen-roll 10 by anaxial projection 16. Thedrum portion 22 is slightly tapered toward the screw-bolt portion 23. A closely coiledspring 25 is coaxially put on thedrum portion 22, having one end fixed to the drum portion and the other free end loosely turning around the screw-bolt 23 portion. A screw-nut 26 is threadedly fitted on the screw-bolt portion 23. The screw-nut 26 is peripherally formed withgrooves 27, which is coupled with theaxial projection 16 on the inner periphery of the screen-roll 10. This means that, as the screen-roll 10 rotates to wind up or down thescreen 30, the screw-nut 26 rotates together with the screen-roll 10 and moves back and forth along the screw-bolt portion 23. The screw-nut 26 is formed with aconical surface 28 for frictionally fitting engagement with the closely coiledspring 25. The inner diameter of the coiledspring 25 is larger than the minimum diameter of theconical surface 28 but smaller than the maximum diameter of the same. - When the screen-
roll 10 winds up thescreen 30 to a predetermined height, the screw-nut 26 has itsconical surface 28 engaged with the free end of thecoil spring 25 in a manner that theconical surface 28 rotates thecoil spring 25 to tighten on thebrake drum 22. Thus, thecoil spring 25 allows no further rotation of the screw-nut 26 or screen-roll 10 to stop thescreen 30 at the predetermined height. The spring-back force of thecoil spring 25 acts on the screw-nut 26 in the direction in which the screw-nut 26 or screen-roll 10 rotates to wind down the screen. The roll-up height of the screen is determined by an axial position of the screw-nut 26 on the screw-bolt portion 23. The axial position is easily adjusted by the use of the dial-ring 40, which is rotatable together with the fixedshaft 20 orextension shaft 21 to move the screw-nut 26 along the screw-bolt portion 23. The dial-ring 40 is easily operated by fingers to adjust the axial position of the screw-nut 26 or roll-up height of the screen while the screen-roll is kept supported by the brackets. - The device of the invention ensures that the roll-up height of the screen is exactly adjusted by a finger operation to move the screw-nut along the screw-bolt portion while the screen-roll remains in the brackets. It is most suitable for use in a roll blind to be required to raise a screen not fully but half. In the case of a plurality of roll blinds which are mounted side by side, the device can easily make all the screen-ends in a line when they are raised, because each trial of pulling and releasing the screen for an adjustment of the roll-up height needs no removal of the screen-roll from the brackets, so that it is very quick and easy to adjust the roll-up height of the screen.
