Definitions
- An adjustable bottom rail for Venetian blinds and use of adjustment means therefor.
- the invention concerns a bottom rail for Venetian blinds comprising means for fastening raising cords and ladder cords.
- the invention furthermore concerns the use of such fastening means.
- Venetian blinds of the type that have freely suspended slats without side guides may be manufactured to precise measurements, i.e. with a pre-defined slat length and height of the Venetian blind, or else only the width and slat length are pre-defined by the width of a window, and the height of the Venetian blind must then be adjusted on location, so that the Venetian blind may be adjusted during use without any part rubbing against the window sill or the similar.
- a Venetian blind consists of a number of ladder cords that carry and adjust the angle of the slats, and raising cords or draw cords that pass through cut-outs in the slats and are fastened to the bottom rail.
- the adjustment of the angle is usually carried out by lifting one part of the ladder while lowering the other, and raising occurs by lifting the bottom rail by means of the raising cords, so that one slat after the other comes to rest on a pack of slats that increases in thickness.
- the bottom rail must have a certain stiffness so that the pack of slats may remain flat and not sag between the points of attachment of the raising cords.
- the ladder cords may either be adjusted by means of an operation that is separate from the raising function or else it is performed by reversing the direction of rotation of the same actuating device that also performs the raising. In the last instance the raising cords are wound around drums in the top rail.
- the strings have to be fastened securely to the bottom rail, and various methods to obtain this are known, comprising threading them through holes that are provided for the purpose.
- a known solution uses holes in the upper side of a hollow bottom rail, through which the strings are threaded, whereupon a knot is tied or a lock is provided on the inside.
- This bottom rail is split lengthwise in two, and during the assembly the ladders are pinched at the outer edges. Thereby the bottom rail is made into a hollow profile with the desired stiffness.
- this solution suffers from the disadvantage that the adjustment is changed by the very clipping together of the two parts of the bottom rail.
- the bottom rail is disposed as an essentially C-shaped profile, in which the inwards facing parts are suitable as recipients of hook-like fingers fitted onto clips that may pushed from above to engage the inwards facing parts and subsequently be shifted along the length of the profile, in that the clips have on their upper side hooks that are suited for gripping a slat for a Venetian blind on either side of a ladder cord and in that the clips each have a hole for fixing a raising cord.
- a ladder may be be cut just below a rung that carries the lowermost Venetian blind slat, the raising cord may be pulled through the hole and provided with a thickening on the lower side, each clip may be clipped to the lowermost slat and finally be clipped into the C-shaped profile.
- a fine adjustment may be performed of the position of the clips in the the bottom rail, and the installation may be finalized by fitting a cap at each end of the profile.
- the lowermost slat creates a lid for the bottom rail, where the thickness of the clip creates a small slit that provides character to the bottom rail by its shadow effect.
- the ladder is attached to the bottom rail in that the lowermost slat is fitted to the bottom rail, i.e. a completely normal placement of a ladder with respect to a slat.
- An advantageous embodiment is particular in that a slider that is fitted between the hook-like fingers has means for gripping the end of a raising cord and may be displaced in the clip, lengthwise with respect to the bottom rail, for individual tightening of the raising cord.
- a slider that is fitted between the hook-like fingers has means for gripping the end of a raising cord and may be displaced in the clip, lengthwise with respect to the bottom rail, for individual tightening of the raising cord.
- a further advantageous embodiment is particular in that means have been provided to create friction, such as barbs, between the slider and the clip to maintain the slider in the final position.
- This embodiment is particularly advantageous when a tall Venetian blind is considered, in which the pulling force in a raising cord may be considerable.
- the invention furthermore comprises the use of a clip as defined in the claims.
- Fig. 1 shows a known solution for fixing of cords in a bottom rail
- Fig. 2 shows a longitudinal section of the bottom rail according to the invention
- Fig. 3 shows a first cross section along the section I-I of the bottom rail according to the invention
- Fig. 4 shows a second cross section along the section II-II of the bottom rail according to the invention
- Fig. 5 shows a third cross section along the section III-III of the bottom rail according to the invention
- Figs. 6a and 6b show a clip according to the invention
- Fig. 7 shows a slider that may adjust the length of a raising cord
- Fig. 8 shows a clip mounted on a bottom rail.
- Fig. 1 a known bottom rail that consists of two parts 1 and 2 that are clipped together to create a closed profile.
- the ladder cords 3 and 3' are held firmly between the two profiles 1 and 2, and the raising cord 4 has been pulled through a hole in the upper part 1 , and a thickening, such as a knot, has been provided for the cord 4.
- the lowermost slat 5 is shown.
- Fig. 2 is shown a longitudinal section of a bottom rail 6 according to the invention, along one of the lengthwise inside edges 6', with a fitted clip 7. Furthermore, the lowermost slat 5 and the next-lowermost slat 5' are shown.
- I-I is indicated the location of a first cross section through the bottom rail 6, the clip 7, and hooks 8, 8'
- H-II is shown the location of a second cross section through the bottom rail 6, the clip 7, and the raising cord 4.
- HI-III is shown a third cross section through the hook-like fingers T on the clip 7.
- Fig. 3 is shown the cross section I-I. It will be seen that the lowermost slat 5 is held by the hooks 8, 8', and that it has a small distance to the bottom rail 6.
- Fig. 4 is shown the cross section H-II. It will be seen that the ladder cords 3, 3' have been pulled under the clip 7 and brought between the clip and the bottom rail 6 until the space between the edges 6' and 6", where they are joined by means of a rivet or the like. The raising cord 4 is pulled through a hole 9 in the clip 7, and a tubular rivet 4' or the like is fitted to prevent its being pulled out.
- Fig. 5 is shown the cross section HI-III. It will be seen that the clip 7 has oppositely directed hook-like fingers T and 7" that may engage below the edges 6' and 6" so that the bottom rail is fixed and may be lifted by pulling upwards on the clip 7.
- Figs. 6a and 6b is shown a spatial representation of a clip according to the invention, in which a number of the features identified above may be seen.
- Fig. 7 a slider for tightening the raising cord. It is shown how one end 11 is shaped to grip a raising cord 4. This will pass vertically through the hole 9 in the clip 7, through the oblong slit S in the slider 10 and horizontally along the lower side of the slider 10, until the thickening 4' provides its end in the gripping means 11. There is furthermore shown a pinion-like corrugation 12' in the shape of a number of parallel barbs that cooperate with similar elements 12 on the clip 7. This serves to retain the slider in the position, in which a tightening of the raising cord has been obtained.
- a set of ladder cords 3, 3' may be cut just below a rung that carries the lowermost Venetian blind slat 5, the raising cord may be pulled through the slat and through the hole 9 in the clip 7 and be provided with a thickening, such as a rivet, on the lower side.
- Each clip 7 may be clipped to the lowermost Venetian blind slat by means of the hooks 8, 8', and may finally be clipped into the C-shaped profile 6. Fine adjustment of the position of the clips along the bottom rail 6 may be performed, and the installation may be finalized by means of a cap at each end of the profile.
- the lowermost slat 5 becomes a lid for the bottom rail 8, where the thickness of the rail creates a small slit that provides character for the bottom rail by its shadow effect.
- the ladder cords 3, 3' are fixed to the bottom rail, because the lowermost slat is fitted to the bottom rail, i.e. a completely normal placement of a ladder with respect to a slat.
- the distance between the next- lowermost slat and the lowermost slat/bottom rail hence becomes quite habitual.
- the clips may be slid lengthwise out of the bottom rail, so that the hook-like fingers 7, 7" are liberated, and the thickening 4' may be fitted correctly to the raising cord 4.
- the clips 7 may be be clipped back in place in order that the hook-like fingers 7, 7" engage the inwards facing parts 6', 6" on the bottom rail 6.
- a post- adjustment may be made by freeing the lowermost slat from the hooks 8 on each clip 7, the raising cord in question may be adjusted by displacing the slider 10 in the gap between the two parts 6', 6" in the bottom rail, and the lowermost slat 5 is again clipped on.
