Description

Tassel for blind cords Aim of the invention The following invention is it referred as the title describes as a tassel for blind cords, of the type that has minimum two independent parts linked to the end of both cords to operate a blind and some means to retain the mentioned independent parts in an assembled position which makes a tassel to operate the blinds, allowing the mentioned means to separate the parts when a force is applied between the cords associated between them; being able to be, by extension, cables, cords, chains, tapes or any other equivalent element, as this does not affect the essence of the invention.

Application field of the invention This invention is applicable in the curtain production, especially in venetian blinds and roman shades.

Precedents of the invention.

Cettain blinds as venetian blinds and roman shades have several operating cords which should be moved simultaneously to keep the bottom of the blind in a horizontal position during the rising or lowing of it.

To make easier the simultaneous movement of the cords, it is usual to pass the ends through a hole in a tassel, fixing the cord ends between each other by a knot.

UFEN TD PUBLZC ll‘.lSFECTEi}?J UNDER szcnaiu 23 Arm BESLE 23 Jittl. fin. ....... ...... .. at IE ;'3:d’1‘30 This knot determinates that the ends of the cords make a closed and resistant loop that could be especially dangerous for young children by suffocation risk while they play with the blind cords.

In the utility model ES 1073373 U, which belongs to the same holder than the present invention, it is described as a tassel for blind cords which allow the splitting in case of applying any force between them, avoiding this way the suffocation risk.

The solution proposed in the mentioned model ES 1073373U consist in using a tassel made of of two independent parts which makes other perimeter portions of the tassel, which have some grooves in the confronted faces to achieve a correct centering in the assembled position, retained by magnets in the assembled position and the separation of the parts that makes up the tassel when there is a force applied to the operating cords strong enough to defeat the magnet attraction.

This tassel, it fulfills the suggested aim, has the inconvenient that the magnetic resource make the cost very expensive to produce the tassel.

Description of the invention The tassel for cords objective of this invention, being of the type: made of at least of two independent parts associated at the end of the blind operating cords with a retention device of the mentioned independent parts when in assembled position, which makes a complete operating tassel for the cords, allowing these devices to split when there is a force applied between the associated cords, allowing to produce the same specifications without using the magnets reducing the production cost.

Therefore, in accordance with the invention, the retaining device of the independent parts which makes the tassel, are made of an elastic retention piece which embraces in the outside keeping them in group when assembled position. ' It is worth mentioning that this elastic piece can have a ring shape, closed or open, made with elastic materiat, when embracing the independent parts which makes the tassel, keeps them together in the assembled position; when there is a force applied of the loop made by the ends of the cords associated to them, they separate side ways deforming the retention elastic piece leaving the parts free from the plastic piece.

According to the invention, the independent parts have in the outside a groove which has a channel shape around the tassel in the assembled position, in which fits the retention elastic piece.

The mentioned retention elastic piece has a ring shape, open or ctosed, mainly with a general configuration of a “C” shape.

Preferably this retention elastic piece is made of plastic material with the aim of making cheaper the production.

According to the invention, the retention elastic piece and at least one of the independent parts which makes the tassel, have a complementary appendix and groove facing each other to fit in, which establishes the position and orientation of the elastic piece when the tassel is assembled.

This way guarantees the side opening of the retention elastic piece facing with a contact surface of the independent parts of the tassel, allowing the parts to separate easily when defeating the elastic piece resistance in case there is a force applied on the loop made by the ends of the cords associated to the tassel parts. 15130171 Drawings description To complete the description achieved and with the aim of making easier the comprehension of the specifications of the invention, the following memo attaches a set of drawings in which, as an illustration and not limited, we show the following: -Drawing 1 shows an elevated view of the tassel invented.

-Drawing 2 shows an expanded perspective view of the tassel invented in a use position.

-Drawing 3 shows an elevated view of the tassel in drawing 2, divided in a vertical plan in a use position.

-Drawing 4 shows a view from above of the tassel in drawing 2, divided in a horizontal plan.

-Drawing 5 shows a perspective view of the tassel in previous drawings with the two independent parts, associated to the cord edges, separated and with the elastic retention piece dismantled.

-Drawing 6 shows a different option achieved of the tassel in which the independent parts have a cylindrical shape and they are jointed by an elastic retention piece as an open ring.

Preferential invention achievement In the example of achievement showed in drawing 1 it has been presented a tassel (1) as per the invention fixed to the operating cord ends (2122) of a blind (2) venetian type. 15130171 ln drawings 2, 3 and 4 shows in greater detail the tassel (1), which is constituted by two parts (11, 12), same as a truncated cone section fixed to the ends of the respective cords (21 ,22) of the blind.

These cords (21, 22) can be fixed to parts (11, 12) independent by sticking, by stapling as shown in Figure 3, or by any other means, as this does not affect the essence of the invention.

The mentioned parts (11, 12) externally have independent separate recesses (11a, 12a) which, in the assembled position of the tassel comprise a perimeter channel for mounting an elastic retention piece (3) which in the example shown consists of a plastic piece with a “C” shape and with a taper similar to that the one on independent parts (11, 12).

As seen in Drawing 2 and 3 this elastic piece (3) holds the two independent parts (11, 12) which makes the tassel, allowing however, that this elastic retention part (3) deforms elastically to release the independent parts (11, 12) in case of applying a force between the cords attached (21, 22).

As can be seen in Drawing 4 and 5, the retaining elastic piece (3) and one of the independent pieces (11), which makes the tassel, shows one appendix on their surfaces facing (31) and a recess (11b) complementary coupling, which establish a certain position and orientation of the elastic piece (3) in the assembled position of the tassel. in this case the coupling of the appendix (31) and the recess (11b) determines that in the assembled position, the opening side of the elastic piece (3) has to face the flat face of contact of the independent parts (11, 12 ), making easier the splitting and releasing the parts (11, 12) in case pressure lEt3.37t‘ ’E73j°i771_ is applied inside the loop formed by the cords (21, 22) attached to the mentioned parts (11, 12).

It is worth mentioning that the number of independent parts making up the tassel will depend on the number of the btind operating cords, and that the shape of these independent parts can be different, keeping in any case the recess designed to form a perimeter channel for mounting the etastic retaining piece around them.

In the variant achievement shown in Drawing 6 the tassel is constituted by three parts (11, 12, 13) in this case cylindrical, associated to the respective cords (21, 22, 23), with corresponding recesses (11a, 12a , 13a) for mounting the corresponding retention elastic part (3).

Once described the nature of the invention as well as an example of achievement, it is stated that the materials, shape, size and arrangement of the elements described can be modtfied, provided that this does not alter essential features of the invention as claimed below.
