Description

Taco perfected.

Object of the invention

The present Utility Model application Its purpose is to register an improved taco that incorporates Remarkable innovations and advantages.

More specifically, the invention makes reference to a cue that greatly improves the characteristics of holding the block in a plasterboard on which the same.

Background of the invention

A wide variety is available in the market of studs generally formed by an elongated body in whose inside there is a drill or hole that extends longitudinally and through which the screw is introduced Fix on the wall.

A first type of taco known is that constituted by arms that are joined in the center of some fins, which allows that when the screw is introduced through the head of taco and a central tower, the fins move angularly, without However, due to the configuration of this type of block the angular displacement is limited to a maximum of 180 degrees, thereby limiting the use of the block to particular thicknesses of the plates.
cast.

A second type of taco known and, widely known in the sector, presents its structure of arms and fins composed of six faces, which reproduce symmetrically with with respect to the central axis of the block. This implies that when it is it is necessary to insert the plug into the hole made in a plate of plaster it is necessary to regroup all these faces, resulting in a volume that requires wide holes, so it is necessary the use of more powerful drill bits and pressure elements and screws oversized, so they are usually manufactured to diameters 10 or more millimeters.

It is for all the above, that there is a need of finding a novel taco configuration.

Description of the invention

The present invention has been developed with the in order to provide an improved taco that solves the drawbacks mentioned above, also providing other additional advantages that will be apparent from the description which is accompanied below.

It is therefore an object of the present invention provide an improved block of the type comprising a body of plastic material presenting a taco head that It has a hole that starts at the rear end and extends to the taco head length provided for the introduction of a screw or similar, in which they protrude from the front end from the head of taco and diametrically opposed a couple of folding fins, such folding fins being joined together to through respective arms that join in a central tower with a through hole aligned with respect to the bore of the head of Taco. In particular, this cue is characterized by the fact that each of the folding fins has a widening in the internal face thereof, which extends from the region in the which a folding flap is attached to its respective arm, in the direction at the free end of the folding flap, and each arm being joined in the central area of its respective folding fin.

Thanks to these features, the fact that each arm is attached in the central zone of its respective fin Folding allows angular displacement of the fins Folding exceeds 180 degrees unlike the prior art, which makes it possible to use the block in plasterboard of different thickness, expanding its application possibilities. It should be noted that the aforementioned widening serves as support for the arm when the screw is introduced and allows the distribution of loads longitudinally in the folding fin which results in a better Taco hold on the plasterboard.

On the other hand, another advantageous aspect regarding to the second type of taco known described above only presents four faces (fin folding-arm-arm-fin folding), so double-sided reduction facilitates the use of smaller holes and screws, greater ease of assembly not having to make great pressures for its introduction and less expensive tacos. In addition, it allows the use in diameters from of eight millimeters.

Other features and advantages of taco perfected object of the present invention will be apparent to from the description of a preferred embodiment, but not exclusive, which is illustrated by way of non-limiting example in the accompanying drawings, in which:

Description of a preferred embodiment

As shown in the attached figures, it appreciate an embodiment of an applicable block for fixing screws on a wall or surface to be treated. More particularly, the block comprises a body of plastic material presenting a head of block (1) that has a hole (2) that starts from the rear end and extends along the taco head (1) provided for the introduction of a screw (3), in which they protrude from the front end of the cue head (1) and diametrically shaped opposite a pair of folding fins (4). These folding fins (4) are linked together through respective arms (5) that are joined in a central tower (6) with a through hole that is located aligned with respect to the taco head bore (1).

Additionally, each of the folding fins (4) has a widening (40) on the inside of the themselves, which extends from the region in which a fin folding (4) joins its respective arm (5), in the direction of free end of the folding flap (4).

The rear end of the cue head (1) it has a flange (10) that protrudes diametrically towards outside.

It is worth mentioning that the whole length of the taco is a mere example since it is evident to any expert in the field that different lengths of the cue head (1) depending on the thickness of the wall or surface in which it must be installed in an extensible block.

The details, the shapes, the dimensions and other accessory elements, as well as the materials used in the manufacture of the improved block of the invention may be conveniently substituted by others that are technically equivalent and do not depart from the essentiality of the invention nor of the scope defined by the claims included in continuation.

Claims (2)

1. Improved block comprising a body of plastic material having a block head having a hole that starts at the rear end and extends along the block head provided for the introduction of a screw or the like, in which they protrude from the front end of the block head and diametrically opposed a pair of folding fins, the folding fins being joined together through respective arms that are joined in a central tower with a through hole aligned with respect to the hole of the taco head, characterized by the fact that each of the folding fins has a widening in the internal face thereof, which extends from the region in which a folding fin joins its respective arm, towards the end free of the folding fin, each arm being joined in the central area of its respective folding fin. 2. Improved block according to claim 1, characterized in that the rear end of the block head has a flange protruding outwardly.
