Abstract

The plate has a body with a series of holes, at its lower part, for suspending metallic chains. A flange is present in a central part of one side of the plate. The flange separates plates when the plates come together during their movement, while preventing the chains from entangling. A central upper part of the plate is extended into a head. A base (15) and a cover (16) of a clamp constitute a space to surround the head with a clip of collets.

Description

The present invention relates to carrier plates used for suspend vertical curtain blades, especially blades made of rows of metal chains for use in curtains, these wafers being essentially characterized in that their use is universal, i.e. immediately applicable to the various types of travel amounts on existing slide in the trade, and in that they are provided with a notch of the characteristics of which will be detailed below.

Are usually well known curtains formed by vertical blades and provided with devices enabling them to be moved on a suitable slide, installed for this purpose, so that they rotate in the direction of their vertical axis, which allows to position the blade so that it allows more or less visibility large and, therefore, a passage of light more or less big. The moving on this slide allows, as we know, to cover all or part of the space where the curtain has been installed, until it is completely folded and occupies only a minimum space on one end of this space that it covers.

The platelets known up to now have the disadvantage of their resistance limited, so that in the case where they would be used for blades having a weight considerable, such as the blades of rows of metal chains, they deform because they are unable to bear all the weight.

Another disadvantage that currently exists is the impossibility of use universally given the diversity of amounts to set the platelets and their adaptation on the slide of displacement.

Finally, we must also note, as a disadvantage, the ease existing platelets, that the amounts of fixation are loose because of the high weight, resulting in the accidental fall of the blade of curtain, with the danger that this represents.

The support plates with a safety catch, object of this utility model, appropriately solve the disadvantages mentioned because, in addition to a structure new enough reinforced to prevent deformation by being overweight, it offers a fixing area that is immediately adaptable, by its shape, to various types of commercially available amounts and, ultimately, it has a easy to place device, similar to a flange, guaranteeing with safety maximum that the mounting amount is removable and that it moves, whatever it is.

In order to describe with all the details the characteristics of the plate of object of this invention, drawings are appended in which are represented as a non-limiting practical example, one of these platelets.

According to these drawings, the support plate object of this patent of invention and provided with a safety catch and intended to suspend the blades curtains, consists of a laminar body, with a rectangular structure and symmetrical (1), preferably manufactured by extrusion or injection, to the part bottom of which it has a series of equal circular holes (2) preferably aligned and equidistant, so that the rows of metal chains (3) forming the curtain blade is suspended there.

From the central part of one of its faces, in longitudinal position and perpendicular, a flap or flange (4) trapezoidal profile, not very high, emerges, which provides by its position and its characteristics a greater resistance to the bending of the wafer (1), avoiding the possible deformation of this wafer (1) when it supports a considerable weight of rows of chains (3).

Moreover, the size and the arrangement of this flange (4) make the plates (1) remain separate as they accumulate due to displacement, avoiding that the rows of chains are mixed, this plate (1) having in addition the most small duly staggered (1a) and (1b) so that the correct recovery is easier when all the support plates (1) are deployed.

The upper central part of the support plate (1) is extended in a head (5) precisely structured to allow immediate adaptation to different amounts existing in the trade. For this, two small flanges (5a) and (5b) are there, protruding from the upper edge of the head (5) to make the positioning and fixing the amount easier, edges that are located symmetrically on this edge.

On the back side of the own head (5) and covering the back side of the plate, there are two parallel and identical legs (6) (6 ') delimiting a central opening (7) of this head (5).

This central opening (7) is an essential characteristic of the invention which is described and has a periphery having the following forms:

First, a rectangular lower zone (8) delimited on the face rear of the wafer by the inner edges of the two legs (6) (6 '). This area (8) has two expansions in the opposite direction quadrangular (9,9 '), ending in an upper zone having a trapezoidal shape (10) while the upper edges of the quadrangular expansions (9) (9 ') are the beginning of inclined ramps (11) (11 ') upwards and outwards as a recess from this zone lateral lugs (6) (6 ') of the opening (7). This form of opening (7) allows any of the many amounts existing in the trade, can be placed, suspended and adjusted correctly by its hooks.

A model type of these amounts is shown in Figure 12, as a sample or example of those commercially available. They own always an element which will be fixed to a head (5) of the support plate (1), in ending on the upper fastening and sliding gear on the curtain slide (not shown)

In the example of the amount of FIG. 12, a model of the "pincer" type (12) is shown which is extended by its upper part on a cylindrical pivot (13), common to the various types of amount, by having a clip (14) on its inner face.

The safety element available to the support plate (1) which is the object of this invention consists of a flange composed of two fundamental pieces, i.e., by a base (15) and its cover (16), which are fixed together by means of screw (21), when the base and the cover face each other and are aligned so that that they coincide.

Both the base (15) and the cover (16) of the flange are preferably obtained by molding. This base preferably has a prismatic shape rectangular, having a large recess, also prismatic (17) which, at its tower, has on its central part a second recess also prismatic rectangular (18), with its inclined front part (19) of about 41 °, an inclination slightly wider than the recess (18), and therefore its ends are sides of the upper recess (17). This base (15) is perfectly symmetrical.

The cylindrical orifices (20) suitably screwed, will allow the introduction of these screws (2 1) closing the flange.

The cover (16) with the same surface dimensions as the base (15) but smaller, offers a central rectangular prismatic recess (22) and two cylindrical end holes and bevels (23) whose situation coincides with that of the holes (20) for the placement of said closure screws (21). This lid (16) is also perfectly symmetrical.

All the hollows of the base (15) and the lid (16) when united forming the flange, constitute a space to perfectly surround the head (5) of the support plate (1) with the clip (14) of the amount (12) placed therein (see the example shown in Figures 12 and 13), avoiding that it detaches unintentionally, which would cause the fall of the blades of rows of chains which are hanging from the curtain of this support plate (1).

Thus, at the moment when the clip (14) of the amount (12) is suitably attached to the opening (7) of the head (7) there is on both sides, front and rear, the cover (16) and the base (15), placing the area of the upright (12) which must remain united at the head (5) inside the hollow formed by the recesses (17), (18) and (22) in then strongly fixing the flange by means of clamping screws and fixing (21). A reverse action, separating the base (15) and the cover (16) will allow the separation of the amount (12) when one wishes to manipulate a blade of rows of curtain chains suspended from the support plate (1).

As described and given the special characteristics of the entrants that the base (15) and the cover (16) of the flange have, it can be used immediately on all kinds of amount of the many existing in the trade.

The subject of this invention having been sufficiently described, it should be pointed out that any variation in size, shape, finish and appearance, as well as the type materials used for the implementation of the object of the invention, will not alter nothing the spirit of this utility model summarized in the appended claims.
