Abstract

The suspension plate (1) for a vertical blind is made of a rigid strip with holes along its lower edge to receive suspension chains forming the blind. The plate has a horizontal flange which is trapezoidal and has a central upper opening. The plate spaces the chains to prevent tangling and a security clip (25) is placed laterally under pressure onto the hook (12) of a suspension upright to prevent the hook opening.

Description

The present invention relates to plates for the universal suspension of vertical slats of blinds, in particular slats formed by strings of metal chains which are supplemented by a safety device and whose essential features are described below.

We know and use as practical and decorative elements, the slides for blinds with vertical slats provided as we know with mechanisms allowing that each blade turns on its vertical axis, in order to allow the passage more or less large of the light as well as moving all of the slats from one position to which the whole space is covered where the blind is installed, until folding it up completely on one of the sides while occupying a minimal space.

These practical and decorative blinds already known, as indicated previously, currently have the disadvantage that for some implementations practical, like for example the lamellae constituted by chains of chains metallic, the plates supporting these lamellae which, in the implementation indicated as example will be very heavy, are unable to support the weight of the slat corresponding, and they deform and break, with all the disadvantages that that represented.

In addition, there are many types of sliders for blinds in the market, which have hooks or uprights having various kinds and shapes, and therefore, there the inserts must be appropriate for each case and, then, there is no inserts on the market which can be used for all upright models known.

The plates for hanging vertical slats object of this model utility are an advantageous solution to the disadvantages mentioned above, they offer also a safety device guaranteeing the positioning of the assembly without it the possibility exists that the vertical strip accidentally comes off as it will described below.

To make this description easy to understand, a series of drawings is attached, in these drawings there is shown by way of non-limiting example, a practical implementation of the plates provided with the safety device object of this invention.

finally, Figure 19 is a perspective view, and on a larger scale, of this safety device.

According to the drawings, the plates for hanging vertical slats blinds, fitted with a safety device, consist of a laminar body (1), extruded or injected, having at its lower longitudinal region an aligned series of holes (3) intended to suspend the chains of chains (4) there.

The central upper part of the body of the plate (1) widens into a head (5) intended to connect the plate to the various kinds of uprights existing in the market and which have been shown by way of example.

On one face of the body (1) emerges longitudinally and perpendicularly a flap (6) with a not very high trapezoidal profile, in order to keep the gap between the plates when accumulated as they slide on the slide, as is shown next to Figure 7, and prevent the chains (4) from hanging on to the others, because when they are folded or deployed, they collide with each other others, the body of the plate (1) also having its lateral ends which form steps (1a) and (1b), to facilitate their correct and orderly overlapping, when all the plates (1), and with it the corresponding vertical strips, are deployed. This flap (6) will make the whole more rigid and more resistant and will constitute the element which makes the office of retractor between the contiguous plates.

The head (5) has been drawn as indicated above, so that it can adapt to the various types of amounts existing in the market, which is a essential characteristic of this utility model. This head has a rectangular shape of which emerge two ledges which protrude (5a) and (5b) on its upper side, to better fix the hook of the upright, edges which have a square shape or rectangular and which are located symmetrically on this edge or upper side.

This hole (7) of the head (5) which constitutes the essence of the invention, has a profile having the following characteristics: A rectangular lower zone (8) provided with two enlargements (9) also rectangular, one on each side of its part upper and then an upper trapezoidal area (10). This special drawing of the hole (7) allows the hooks of the various uprights to be suspended and adjusted correctly existing. It is, therefore, a head with universal attachment.

The various uprights on which the plates (1) are fixed are shown with reference to FIGS. 8, 11, 13, 15 and 17, as more characteristic variants of the various genres existing in the market. They all have something in common or amount on which the head (5) of the plate (1) will be fixed, as well as the upper part by means of which they will be fixed on the slide (11) of the blind.

In Figure 8, with Figures 9 and 10, there is shown an amount (12) of the "clamp" type provided with a vertical notch (13) and on its inner walls, the projections retainers (14) which extend at their upper part with the cylindrical pivot (15) common to all uprights, which secures it to the travel train, not shown, by the blind slide (11).

The model in Figure 11, also drawn next to Figure 12, has a hook 16, not very high and not very wide almost the same as its rectangular base (17), ending in a triangular vertex.

The model in Figure 13, also drawn next to Figure 14 is cylindrical (18), practically in extension of the pivot (15) and it takes the form of a pliers, with its vertical notch (19), an internal projection (20) and another to the part bottom of the opposite face (21).

The model in Figure 15, also drawn next to Figure 16, has a hook (22) very large and straight horizontal end. In this last figure, we observe that as this hook is larger, it can be introduced precisely in the enlargements (9) of the hole (7) of the head (1). The effectiveness of the invention is therefore demonstrated.

The model in Figure 17, also drawn next to Figure 18, has a hook (23) relatively narrow in relation to its length, its end ending in point, which emerges from a cylindrical base (24) having a diameter smaller than the pivot (15). In this case, it can be suspended by the trapezoidal upper part of the hole.

The various hooks drawn, as well as the gripping action of the uprights of the pliers, will fix the head (5) of the plate (1), thanks to the special shape, already described above, of the hole (7) of this head.

The safety device, an additional element of the brochure covered by this utility model, has the purpose of locking the hook of the upright, whatever the model, when it has been placed and suspended from the head (5) of the plate (1), thus preventing this plate comes off involuntarily, and with it the strip formed by the chains (4).

This safety device consists of a body (25), injected or extruded in "U" shape, thus constituting a gripper which acts on the upright and the head of the plate, surrounding them both and preventing the hooks can open and the plate (1) comes off involuntarily, as we already have indicated.

The rectangular body (25) which constitutes the clamp of the safety device has an entrance (26) narrower than the interior so that it cannot exit when it has been entered under pressure. In its central part, it has a recess (27) to allow correct centering with the post once it is placed. Its bottom (28) is rounded, to allow proper bending without breaking, while the edges of the outlet (26) are rounded, outside and inside, to facilitate entry or exit action, by exerting horizontal pressure in the desired direction: in the direction of the arrows indicated opposite the various figures, to place the safety device (25) in firmly fixing the head (5) of the plate (1), or in reverse to release it.

An essential feature also of this application is the fact that the safety clip (25) shown opposite Figure 19 is used for its use immediate on all kinds of existing studs, as has been observed along the description, and in accordance with the various drawings.

The object of this invention being sufficiently described, it should be noted that any variation in dimensions, shapes, exterior appearance and types of materials used for the practical implementation of the plate with the safety device which has been described, will in no way alter its essential character.
