CZ302112B6 - Bearing attachment of roller shutter control elements in upper load-bearing section - Google Patents

Abstract

In the present invention, there is described bearing attachment (3) of roller shutter (2) control elements (2) in upper load-bearing section (1) having its lower wall (12) provided with at least two penetrations (13), wherein the bearing attachment (3) is adapted for both placing end sections of a textile strip (4) and a ladder (5), and ensuring their passage out via a bottom base (311) of its body (31). The invention is characterized in that said bearing attachment (3) is mounted in the load-bearing section (1) removable outwardly via the penetration (13) of the lower wall (12), and namely from below insertable installation of the whole assembly complex of the bearing attachment (3) including attached end sections of the textile strip (4) and the shutter (2) ladder (5).

Description

Technical field

The present invention relates to a new structure for attaching a bed of control elements of blinds, in particular textile strips or cords, in an upper support profile.

BACKGROUND OF THE INVENTION

At present, a number of constructional solutions of horizontal blind control systems are known, which depend on the manner of attachment and winding of the control elements, especially of textile tapes or cords. Such solutions are described, for example, in U.S. Pat. Nos. 4,886,102, 5,318,090,

WO 93/03250, US 4,621,673, GB 2,163,202 or EP 373,787. A common feature and drawback of all these solutions is that the control systems are inserted into the upper support profile of the blind either from the side and especially from above, so that during assembly first, the control system must be slid into the profile before the textile strap or cord can be attached. This assembly by pulling the controls through the narrow holes in the profile is relatively demanding and time consuming and requires great skill of the fitter.

SUMMARY OF THE INVENTION

These disadvantages are solved to a large extent by the attachment of the bed of the blinds control elements in the upper bearing profile, whose bottom wall is provided with at least two intersections, where the bed is adapted both to accommodate the end portions of the textile tape and the ladder . It is an object of the invention that the bed is mounted in the support profile removably outwardly through the penetration of the bottom wall, by retractably accommodating the entire bed plex mounting assembly 30 including the attached textile belt end portions and the louvers ladder.

It is a further object of the invention that the base of the body is provided on two opposite sides with circumferential flanges whose width is greater than the width of penetration of the bottom wall of the support profile, and at the same time the bed is provided with fixing elements.

In a preferred embodiment, the fixation elements are formed by elastically deformable pre-spring tongues, which are guided obliquely downwards and whose compressible free ends extend beyond the lateral outer contour of the body beams.

A new solution for attaching the bed of the blind control elements in the upper support profile achieves a higher effect by significantly simplifying and shortening the overall mounting of the blind when the laborious and lengthy stepping of the ladder to the rolls directly in the support profile is eliminated. This will greatly reduce the cost of manufacturing blinds, which will have a particular impact on reducing their total cost. It is also logical to reduce the laboriousness of possible blind repairs, by simply removing the bed from the profile, thereby reducing the time for disassembly and reassembly.

BRIEF DESCRIPTION OF THE DRAWINGS A particular embodiment of the invention is shown schematically in the accompanying drawings, in which Fig. 1 is an overall axonometric view of the blind before sliding the bed into a profile with different arm heights

Fig. 2 is a vertical longitudinal section of a portion of the profile of Fig. 1 with the bed inserted without the lid; Fig. 3 is an axonometric view of the bed without the louver controls mounted; Fig. 5 is an axonometric view of the Fig. 3 bed with a lid and inserted into a profile with the same height of the legs of Fig. 6. is an axonometric view of the construction node of FIG. 5 with an alternative embodiment of the locking elements.

DETAILED DESCRIPTION OF THE INVENTION

The actual constructional node, which is solved by the invention, consists of an upper support profile also differently shaped and adjusted to the height of its arms 11, for attaching to the window frame, securing the cover strips (not shown) and securing the blinds. is provided on its bottom wall 12 with at least two intersections 13, preferably of rectangular or rectangular cross-section, the size and shape of which correspond substantially to the size of the outer contours of the body 31 of the shutter control body 2. The body 31 consists of a base 311 vertically erected two shaped beams 312 whose faces 3121 are connected and whose inner seats 3122 are freely rotatably seated hub 33 and roll 34, which are slid together with their coupling sleeves 331, 341 provided with identical slots 332, 342 serving The hub 33 is then further provided with a handwheel 333 for facilitating assembly work and the roll 34 is provided with a roller 343 for receiving the ladder 5. At their lower portions, the beams 312 are provided with elastically deformable spring-loaded fixation elements 3132, e.g. 2 and 3. The base 311 of the body 31 is then provided with peripheral edges 3111 on the sides of the faces 3121 of the beams 312 to prevent it from falling through. 3 into the inner space of the support profile J when it is pushed into this profile J from the outside. Further, the body base 311 is provided with central openings 3112 formed opposite slots 332, 342 to allow the textile strip 4 to pass outside the support profile J, and through side openings 3113 to ensure passage of the ladder 5 ladder 2. serving both to protect the structural nodes 33, 34 from falling out and to fix their position in the inner seats 3122 of the beams 312. The lid 6 can then be provided with differently located and shaped relief holes 61 or spacers 62 for aligning the bed 3 in the support profile Different embodiments and shapes when the column-shaped spacer 62 is shown in Fig. 4 and the canopy-shaped Fig. 5.

When assembled, the ladders 5 and the textile straps 4 are threaded through the slats 2 of the blinds 2 and their end parts are fastened to the roll pulley 34 and the slots 332, 342 of the coupling sleeves 331, 341 after passing through the respective holes 3112 and 3113. it is inserted into the seats 3122 of the beams 312, or the bed 3 is covered with a lid 6, and substantially the entire blind 2 is inserted from below into the intersections J3 of the bottom wall 12 of the support profile J where it is engaged by the spring elements 3123 and the peripheral rims 3111. through the axial holes of the hub 33 and the roll

34 extends the connecting shaft (not shown), whereby the assembly of the blind 2 in the support profile J is completed. The disassembly is carried out analogously, when the fixing elements 3123 are first unlocked by compression and then the entire assembly of the bed 3 is pulled out of the support profile J.

The described embodiment is not the only possible construction according to the invention, but without affecting its nature, the spring-loaded tongue-like fixation elements 3123 can be replaced by freely removable pins 9 as shown in Fig. 6, or by other conventional retaining means to prevent spontaneous ejection. from the inner space of the bearing profile

3111 need not be formed on the base 311 then on the sides of the faces 3121 of the beams 312 but on the adjacent sides, i.e. perpendicular to the axis of the hub 33 or roll 34, and the fixation elements 3123 can be formed on the faces 3121 of the beams 312 thus parallel to the longitudinal axis

Industrial Applicability o o The mounting of the blind control element bed in the upper bearing profile can be used for all types of interior and exterior blinds for various types of bearing profiles, including all-closed, and arbitrary moldings of the rails, including the one-arm rail.
