    KNOB ARRANGEMENT FOR OPERATING MECHANISM OF A BLIND FIELD OF THE INVENTION The invention relates to a device, to be installed in the frame of a Window, for operating avenetian blind or similar device located behind the Window and regulating the entry of light.The device usually comprises at least one knob or similar and means for connecting its rota- ry movement to the mechanism controlling the attitude of the venetian blind.
    BACKGROUND TO THE INVENTION Operating devices of venetian blinds installed between Windows have remained the samesince as long ago as the l970s. In a venetian blind, there is an upper frame or similar, inWhich the mechanism controlling its attitude is located, and through Which the lifting cordsrun. In the frame of the Window, at the height of the upper frame, are feed-through holes andan adapter piece, through Which the adjusting cable and the lifting cord are brought to thefront of the frame. A rotary-knob-equipped rod, for Which there is a holder in the frameperrnitting the rod to rotate, and Which extends doWnWards to a suitable height, is connectedin front to the control cable. In the same Way, the lifting cord extends doWnWards to a suita- ble height, and in the frame there is a suitable holder for securing it.
    Such traditional operating devices for venetian blinds are aesthetically intrusive and taste-less. There is an obvious need to develop a less intrusive, more modem solution, Which suitsthe environment better and merges into it. NoWadays, the best possible air-tightness is also demanded from Windows. Traditional venetian-blind operating devices are not air-tight.
    Various solutions have indeed been proposed for venetian-blind operating devices, in Whichthey are located either inside the frame of the Window or door, or behind the frame. Thesolutions also meet the demand for air-tightness. One such solution is disclosed in publica-tion WO 02095177 A1. In it, the Window frame is equipped With feed-through sleeves,through Which a control element extends to the other side of the frame, and to Which a con-trol knob is connected on the front side of the frame, and a gearWheel and rod arrangementon the rear of the frame, Which transmits the attitude of the venetian blind to the controlmechanism. The control element extending through the feed-through sleeve is, in addition,ho llow, and through it the venetian-blind lifting cords are brought to the front of the frame, Which are then connected to a lifting-cord pulling and tensioning knob, fitted inside the con- 2 trol knob. The drawback of the solution is that it has many mechanical parts to be f1tted toeach other. The solution is thus expensive, and its complexity is a risk in terrns of operating reliability.
    A venetian blind can be installed entirely or partly already by the window manufacturer, oras a retrofit. In each case, it is advantageous for the operations required for the installationof the venetian blind to be as simple and quickly performed as possible. From the point ofview of the end user, the control devices should be simple and durable, and the operation of the blind easy and fianctional.
    Finnish patent 124626 disclo ses a venetian blind operating device, in which there are twoknobs, each of which can be used both as a lifting-cord knob and as an attitude-controlknob. In the knobs are grooves for a different number of cords, so that their installation de-mands care, so that the lifting cords are not attached to a knob intended for a different num- ber of cords.
    SUMMARY OF THE INVENTION The invention is intended to disclose a better knob arrangement than known devices for op-erating a venetian blind, a curtain, or similar, regulating the entry of light, and installed be- hind a window and between its frames.
    One embodiment of the invention is intended to ensure the locking of either knob of the arrangement tightly to the frame of a window, door, or similar.
    One embodiment of the invention is intended to create a knob arrangement, which lies more tightly on the frame than previously.
    One embodiment of the invention is intended to create a knob arrangement, which compris-es separate knobs for controlling the attitude of a venetian blind and for the lifting cords ofthe blind.
    One embodiment of the invention is intended to create a knob arrangement, in which thephysical shape of the knobs is similar, but the visual appearance of which, for example, can be altered to differ from each other. 3 One embodiment of the inVention is intended to create a knob arrangement intended to con-trol the height of a device controlling light, fitted between the frames of a glass f1tted in two frames.
    The inVention is based on the fact that in each of the knobs of the knob arrangement there isa body, a shaft, and locking elements for holding the knob in a hole in the frame when the shaft of the knob is pressed into the hole in the frame.
    According to one embodiment of the inVention, there are locking elements in the body ofeach knob for holding the knob in the hole in the frame when the shaft of the knob is pressed into the hole in the frame.
    According to one embodiment of the inVention, there are locking elements in the shafts ofthe knobs for holding the known in the hole in the frame when the shaft of the knob is pressed into the hole in the frame.
    According to one embodiment of the inVention, the knob arrangement includes a sleeve, to which the locking elements of the knobs attach, f1tted to the hole in the frame.
    According to one embodiment of the inVention, in the body of at least one knob there is at least one protrusion, which locks to the sleeve by shape-locking.
    According to one embodiment of the inVention, in the knobs there is a sealing surface,which is preferably curVed or straight and most preferably rotationally symmetrical aroundthe shaft of the knob, extending outwards from the base of the shaft and extending in thedirection of the body of the knob.
    According to one embodiment, the locking element of the shaft of the attitude-control knobis a hook formed in the end of the shaft.
    According to one embodiment, the locking element of the cord knob is a protrusion in theend of its shaft.
    According to one embodiment, in the shaft of the cord knob there is a central round hole, onthe outer circumference of which is a wedge-like groove, which narrows from the end of theshaft towards the base of the knob.
    According to one embodiment, in the shaft of the cord knob is a central round hole, on theouter circumference of which is a straight groove, which narrows from the end of the spin-dly towards the base of the knob.
    According to one embodiment, there is a slot in the end of the groove in the shaft of the cordknob, which extends to the base of the shaft and at the end of the groove towards the outer circumference of the knob.
    According to one embodiment, at least the knob°s body, shaft, and locking elements forrn a single piece.
    According to one embodiment, the sleeve is a single piece.
    We are of the opinion that the operating devices according to the invention are suitable foruse, for example, in all MSE windows on the market. Venetian blinds can both be installedat the window factory and retrofitted by the end user. Because only the knobs need be de-tached from the ready-installed blinds and operating devices for transportation, Windows can be packed against each other, without the installed operating devices in any way in-creasing the need for packing space. As the other components are already installed in thewindow, the installation of the knobs takes only a moment, and the venetian blinds are ready for use.
    The operating device has improved embodiments in terms of child safety.
    The operating device according to the invention can be manufactured for essentially the same costs as existing operating devices. The components are simple and their number doesnot essentially increase. Two knobs are all that can be seen of the operating devices in frontof the window. The other components remain inside the window. The operating devices aretherefore very simple and stylish and do not protrude as irritating structures from the frames of the windows.
    The operating devices according to the invention are also structurally tight, and with their aid it is possible, if desired, to achieve even essentially air-tight solutions. 5 The knobs according to the invention cannot be mistaken for each other in installation andare nonetheless adaptable to several venetian blinds, in which there is a different number oflifting cords. The knobs have the same physical appearance, but their visual form can be changed by altering the colour or decorative patteming of the knobs” covers.

    DETAILED DESCRIPTION OF THE INVENTION A description of an application of the invention can be found in Finnish patent 124626. In it,straight holes, the diameter of which can be, for example, 10 mm, are drilled in the window frame or similar at a suitable height for the use of a device. Sleeves, in which there are col- 6 lars lying on the outer surface against the front surface of the frame, and, slightly raisedfrom this, shoulder rings, are installed in the ho les, making the attachment of the sleeves tothe frame tight and secure. In this example implementation, similar knobs are installed inboth sleeves, With plug parts that are arranged to be pushed inside the sleeves and to settlethere suff1ciently tightly and f1rmly. On the inWard face of the knobs is a suitable hole for attaching the lifting cord, the ends facing outwards from the frame being closed With plugs.
    The knob arrangement according to the present invention includes a cord knob 1 and anattitude-control knob 2. In the cord knob there is a body 3, Which is shaped in the form of atruncated cone. In the edge of the smaller diameter end of the cone, there is a collar 5, Whichedges the end of the cone and inside Which is a recess 6. In the edge of the larger diameterend of the cone of the body 3, there is an inwardly pointing bevel 7. The bevel 7 is intended to create a pleasant appearance and shape for the operation of the knob.
    In the middle of the recess 6 of the body of the cord knob 1 is the knob°s shaft 4, Which ex-tends outwards from the body 3 of the knob. The outer surface of the shaft 4 forms a cylin-drical surface and the shaft connects to the outer surface of the body of the cord knob bymeans of a curved rounding, a sealing surface 8. The sealing surface 8 formed by thisrounding is intended to seal the cord knob 1 air-tightly into the hole in the frame, more spe-cifically into the sleeve of the hole. Though the sealing surface 8 is preferably a rounding, itcan also be some other curved shape facing outwards from the shaft 4, or a straight surfaceslanting at a suitable angle. This sealing surface 8 is intended to press precisely on the innersurface of the hole formed in the frame, for example, of the hole of the sleeve. The outWard-ly facing curved or slanting surface lies f1rmly against the edge of the hole and forms a tightjoint. Because the sleeve°s hole is usually round, the sealing surface is correspondingly rota- tionally symmetrical.
    In the centre of the shaft 4 of the cord knob 1 is a central hole 9, the end cross-section ofWhich is preferably round. The outer surface of the cord knob”s 1 shaft 4 is cut by a groove10, Which extends from the outer surface of the shaft 4 of the cord knob 1 to the central hole9 over the entire length of the shaft 4 from the end 11 of the shaft to its base. The groove 10is wedge-shaped, in such a Way that it spreads out towards the end 11 of the shaft 4. At theend of the groove 10 at the base of the shaft 4 is a slot 13 formed in the recess 6 in the body3 of the cord knob 1. The hole 9, groove 10, and slot 13 form a feed-through for the lifting cords and thus different numbers of cords, for example 2, 3, or 4 cords can be fitted to the 7 feed-through shaped in this Way. Thus one knob can be used for most venetian blinds of different Widths and the need for different components can be kept small.
    At the end of the shaft 4 of the cord knob 1 is a locking tooth 12, Which extends outWardsfrom the edge of the end 11 of the shaft and its outer surface. The shape of the locking tooth12 can vary; it can be, for example, one or more teeth, or some other protrusion. The lockingtooth 12 is intended to lock the cord knob 1 to the sleeve in the frame or to a correspondinghole formed for the knob. Locking ensures that the knob remains in place and that the cordsare locked to the desired attitude. Locking also forms, together With the sealing surface 8, atight joint With the sleeve 22 f1tted to the hole in the frame (Figures 11 and 12). In principle,it can be envisaged that the holes for the knobs are formed directly in the frame Withoutsleeves. The frame Would then have to be of a strong material such as metal or a suff1cientlyhard plastic. A hole formed in a Wooden frame or one of a corresponding softer materialWould not Withstand the Wear of the control cords and the repeated detaching and pushinginto place of the knobs during use. The use of a sleeve also gives the advantage that the con-trol device can be installed similarly in all frames, irrespective of their material and con-struction, as long as the thickness of the frame is suitable for the selected sleeves and knobs.
    The movement of the control cords Will be smoother and Wear Will be less.
    At the opposite end of the cord knob 1 to the shaft, there is, in its outer surface an inWardlydirected slanting recess 15, in Which there is the cover 14 of the knob. The cover can beattached to the knob 1, for example, by a press lock. The task of the cover 14 is to seal thecord knob to be airtight and to perrnit the venetian-blind cords to be installed in the knob. Inaddition, With the aid of the cover, the appearance of the knob can be varied. The covers canbe of different colours or there can be pattems or text on them, for example, the name of themanufacturer or seller (for example, SOLAR). The end and body of the knob and the shapeand size of the cover are the same in the cord knobs and the attitude-control knobs. The ap- pearance of the knobs can be altered by varying the colours or patteming of the covers.
    In the case of its body 16, the attitude-control knob shown in Figures 4 and 5 is the same asthe cord knob. The difference between the knobs lies in the shape of the shaft. Here, theshaft 17 of the attitude-control knob 2 is shaped to be solid and there is a locking hook at theend of the shaft 17. In the locking hook, there is a transverse groove 18 relative to the shaft,a short distance from the end of the shaft 17. The end of the attitude-control knob°s shaft 17is cut in such a Way that the end forms a segment of a circle. In this example, the end of the shaft is a semi-circle 19, the surface 20 of the cut is straight, as are the edges 18 of the 8 groove 18. With the aid of the straight surfaces a side support surface is provided against thejoint element of the venetian-blind°s control element, so that the joint is strong and with- stands use well.
    At the base of the attitude-control knob°s 2 shaft 17 is a corresponding sealing surface 8 tothat at the base of the cord knob°s 1 shaft 4. Here, the sealing surface locks to the edge ofthe hole in the sleeve or similar and locks against it tight, by means of the locking hook 18 - 20 and the venetian-blind°s control elements attached to it.
    The embodiment of Figures 6 and 7 differs from those described above in that the groove 19in the cord-knob”s 1 shaft 4 is straight. The straight groove 19 does not form a wedge, sothat the venetian-blind°s control cords cannot be locked with the aid of the knob. The heightcontrol of the venetian blind must now be done by pulling the cords so far out of the frame°ssleeve that the blind°s lower edge rises to the desired height. After that, the cords must bewound around a cord stud or studs attached to the frame, to lock the cords. Once the cordsare safely attached, the cord knob 1 can be pressed back into the frame°s sleeve and thecords running to the cord stud run through a radial slot 13 in the knob, between the sleeveand knob. This solution is intended to increase safety. In this embodiment, the only possibil-ity to lock the blind to the upper position or a raised interrnediate position is to wind thecontrol cords through the cord stud and press the knob back into the frame°s sleeve. This isa child-safe version. The blind°s control cords cannot remain in a free bunch on the surfaceof the window, into which a child could put its head and be strangled. It is important to takethis into account particularly in windows and doors in which the control devices and thus the cord bunch can remain low down.
    Figures 8 - 10 show an attitude-control knob and cord knob, in which locking to the frameis implemented by a locking element formed in the knob”s 1, 2 body 3, 16. In this example,the locking elements are three teeth 30 formed symmetrically at 120° intervals in the collar 5in the frame 3, 16. The teeth 30 protrude from the collar 5 in the direction of the centralshaft 21 of the knob 1, 2 and are the same in both knobs. The teeth 30 attach the knobs l, 2to the feed-through sleeves 22, one embodiment of which is shown in Figures 11 and 12.The sleeve 22 is formed of a cylindrical sleeve body 24, in which there is a central hole 23for the shaft 4, 17 of the knob 1, 2. At one end of the sleeve 22 is a sealing collar 25. Thesurface of the sealing collar next to the sleeve body 24 comes against the outer surface ofthe frame and thus seals, together with the sleeve body 24, the hole made in the frame. A locking ring 26 extending around the collar is formed on the outer circumference 26 of the 9 sealing collar 25. The diameter of the locking ring 26 is larger than that of the collar 25 andthus forms a step on the outer edge of the collar for the teeth 30 of the knobs 1, 2. The inneredge 27 next to the sealing collar of the hole 23 of the sleeve 22 is rounded to be curved.This surface corresponds to the shape of the sealing surface 8 and can be shaped according to it, so that a suff1ciently tight joint is created.
    When the knob 1, 2 is pushed into the sleeve 22, the knob”s sealing surface 8 presses againstthe inner edge 27 of the sleeve°s 22 hole 23 and seals the feed-through. At the same time theknob°s teeth 30 push over the locking ring 26 and lock the knob in place. The knob can be easily detached from the sleeve by pulling, for the re-adjustment of the cords. Thus, an easy- to-use and reliable knob locking mechanism and tight feed-through can be formed.
    On the outer surface of the sleeve there is ribbing 28 and a collar 29, by which it locked tothe frame longitudinally and rotationally. If desired, an adhesive or some other locking agent can be used to ensure that the sleeve 22 remains in the frame.
    The manner of implementation of the locking mechanism described above can vary. Thenumber of teeth can differ from the abovementioned three, but by using three teeth the lock-ing force is distributed evenly parallel to the central shaft of the knob. The minimum num-ber seems to be two and the use of more than three can increase resistance to wear, but alsoincreases the complexity of the construction and thus mould-making costs. The teeth can bereplaced, for example, by a unif1ed protruding edge, but then it may be difficult to set theforce required for detaching and setting in place to the right level for easy use. A threaded orbayonet attachment is otherwise possible, but these constructions are more expensive anddifficult to use due to the rotary motion required. Locking must be shape-locking to ensurereliability. The locking elements in the sleeves and knobs can be tumed the opposite way round, if this is desired.
    Figures 13 and 14 show one embodiment of a cord knob suitable for use in the embodimentsof the arrangement according to the invention, as well as details of its dimensioning andconstruction, which can be combined with the embodiments of the knobs described above, to adapt them for various applications.
    It can be seen from Figure 13 that in this embodiment the shaft 4 of the knob 1 is slightlyconical, spreading from the free end 11 of the shaft towards the body 3 of the cord knob 1.
    The conicality is very small, on a shaft 4 with a diameter of slightly over 6 mm, the differ- ence between the free end 11 and the base of the body 3 is 0.1 mm (end ø 6.3mm, base ø6.4 mm). With this shaping, the cord knob°s shaft can be made to seal the sleeve well.
    In the centre of the shaft 4 of the cord knob 1 is a central hole 9, which is preferably roundin end cross-section. The outer surface of the cord-knob°s 1 shaft 4 is cut by a groove 10,which extends for the outer surface of the cord-knob°s 1 shaft 4 to the central hole 9 overthe whole length of the shaft 4 from its end 11 to its base. The groove 10 is wedge-like inthat it widens towards the end 11 of the shaft 4. At the end of the groove 10 at the base ofthe shaft 4 is a slot 13 formed in the recess 6 of the body 3 of the cord knob. The hole 9,groove 10, and slot 13 form a feed-through for the lifting cords and different numbers ofcords, for example 2, 3, or 4 cords, can be f1tted to the feed-through thus formed. Thus, oneknob can be used for a large part of venetian blinds of different width and the need for dif-ferent components can be kept small. In these ways, the cord knob 1 is like that shown inFigures 1 and 2. However, there is not a locking stub in the end of this cord knob. In thisembodiment, locking is implemented by friction-lo cking. Most of the locking is formed bythe aforementioned conicality of the shaft 4. The conically formed and gently rising shapeseals tightly to the dimensioned sleeve and the locking force can be adjusted by pressingcord knob 1 lightly or strongly into the sleeve. The dimensioning and shape of the cord-knob”s 1 central hole 9 and groove 10 also relate to the locking of the cords and tightness ofthe construction. The wider part of the groove next to the free end of the shaft 4 is slightlynarrower than the diameter of the central hole 9 of the groove. Here, example dimensionsare a hole diameter of ø 4.3 mm and the groove°s widest point 4 mm. When the cords aretaken to the groove 10 and pulled towards the base of the shaft 4, and the cord knob 2 ispressed into the sleeve 22, the cords press over the edges of the narrowing groove 19. At thesame time, the conical shape of the shaft 4 presses the shaft in such a way that the shaft 4presses sufficiently into the sleeve 22 for the knob to remain in place in the sleeve. Thus,when the cord knob 1 is pressed down to the bottom, it remains on the bottom and the seal- ing surfaces are closed.
    According to different embodiments of the invention, the sleeve can be manufactured in onepiece. In the same way, in each knob at least the body, shaft, and locking elements form oneand the same piece. Thus, separate connectors are not required to attach them to the frameand to lock the knobs to the sleeves, or to attach the knobs to the venetian blind”s controldevices and control cords. The construction is thus very simple. This brings advantages in manufacture, installation, and end use. ll With the aid of the invention, a cord knob can also be implemented in various light curtains,black-out curtains, venetian blinds, and similar to be placed between two glass windows anda frame, which does not have attitude control. In such devices, only the height of the curtainor similar between the glasses is adjusted. The arrangement consists of a sleeve to be in-stalled in the frame and a cord knob shape-locking to it, which can be similar to any of the cord knobs described above.
    The new properties of the various embodiments of the invention include, among others, the following: In previous models, there are two knobs, both of which can act as either rotation or lifting-cord knobs. In each delivery, one item of both knobs is sent for a single venetian blind. Thef1tter selects which knob to install on the basis of the width of the blind (number of liftingcords 2, 3, or 4). The problem is that the knobs can be mixed up in installation; in practicethis is noticed in not being able to lock the blind in the raised position. In the version ac-cording to the invention, there are completely separate cord and rotation knobs. They cannotbe mixed up in installation. The locking shaft of the cord knob operates on a completelydifferent principle, which perrnits the knob to lock 2, 3, or 4 cords. The base of the knobs”shafts is rounded, which seals the knob better against the feed-through sleeve, as a result of which the air-tightness improves.
    At the end of the cord-knob”s shaft is a small tooth and the knob clicks and locks in place when pressed outwards into the sleeve.
    During installation, the cord knob°s shaft acts as a guide for the lifting cords, making it easi- er to push the cords through the knob, thus facilitating installation.
    Design has an important role in the arrangement according to the invention. The shape ofthe knobs is timeless and easily operated. The surface of the body of the knob can be rough-ened, which gives a good grip to fingers. The cover can be, for example, shiny, which willachieve an elegant appearance. Because the covers of the knobs are identical, there is onecomponent less in the arrangement than previously. The knob and the cover can be differ-ently coloured. In this way, altemative appearances can be provided for demanding interior decorators.
