Description

Centering clip

Object of the invention

The present Utility Model application has by object the registration of a centering clip that incorporates Remarkable innovations and advantages over today's systems known.

More specifically, it refers to a staple centering, preferably of plastic material, comprising a substantially hollow cylindrical body for the introduction of a hardware element, which includes a plurality of ribs arranged on the outer surface, including at the end that an extension is located inside a wall or similar  inwardly hollow.

Background of the invention

Currently, the use of tacos is known expansion intended to fix objects or elements on walls hollow

For example, a cue of the type of the present The invention is described in utility model No. U9600081. East taco is equipped with a radial expansion in the form of a washer in the input end of a screw, which is bolted to a conical nut movable axially in a rotating direction, so that when moving inside the block causes its expansion thanks to the body of the block having longitudinal openings, being made in a molded part that at its opposite end at the screw inlet has some flexible strips in solidarity to the nut

However, the fact of the taco present the flexible strips and fins as well as the nut with a threaded interior increase the complexity of the whole set, so that the sum of all these elements can directly affect The overall cost of the product.

Description of the invention

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

The centering clip of the present invention, preferably of plastic material, it is of the type comprising a substantially hollow cylindrical body for the introduction of a hardware element, which includes a plurality of ribs arranged on the outer surface, including at the end that an extension is located inside a wall or similar  internally hollow with a substantially conical contour, and characterized by the fact that the inner surface of said prolongation is smooth and the body is shaped cylindrical as the extension in a single molded piece, and in addition, due to the fact that the diameter of the inner hole of the extension is less than the diameter corresponding to the hole interior of the body substantially cylindrical.

Thanks to these characteristics, you get a system for fixing objects to thin walls with a simplified design that is easy to manufacture and at a lower cost thanks to the fact that the set consists of only one part out of a mold and it is also easy to place in the hole where it should be placed. On the other hand, the fact that the inner part of the extension is smooth facilitates the rotation and the screw insertion in the extension.

Preferably, the truncated conical extension it comprises an elongated cylindrical section that is located in the part hollow interior of the substantially cylindrical body.

According to another aspect of the invention, the body of the clip and the extension are joined by the end of the body cylindrical through an annular junction section of reduced thickness. In this way, the use of a section of reduced thickness allows its breakage during operation, so that the cylindrical body and extension are separated allowing such extension may move in the opposite direction to screw displacement.

Advantageously, the ribs are located of equidistant and transversely with respect to the body cylindrical, presenting a significantly arched contour and being also inclined with respect to the longitudinal axis of the body cylindrical. Thanks to this arrangement as well as the arched shape of  the ribs increases the fixation of the staple assembly in the wall on which it must be located.

Other features and advantages of the clip centering 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 Figures 1 and 2, the centering clip (1) of plastic material of the present invention it comprises a substantially hollow cylindrical elongated body (2) for the introduction of a hardware element, which includes a plurality of ribs (3) arranged on the outer surface which increase the fixing of the clip to a wall.

At the end of the cylindrical body (2) that remains located inside a wall or similar a extension (4) internally hollow contour substantially conical trunk with an elongated cylindrical section (5), being the inner surface of said smooth extension (4). Both body cylindrical (2) as the extension (4) are formed in a single molded piece.

It should be noted that, the staple body (1) and the extension (4) are joined by the end of the cylindrical body (2) through an annular junction section (6) of reduced thickness which can break easily when the screw is turned self tapping when introduced.

On the other hand, the diameter of the inner hole of the extension (4) is less than the diameter corresponding to the inner hole of the substantially cylindrical body (2).

Making particular reference to the ribs (3) are equidistant and transversely located with respect to the cylindrical body (2), each of them presenting a sensitively arched contour and also being inclined with respect to the longitudinal axis of the cylindrical body (2).

In figure 3, the step-by-step operation of the centering clip (1). In bliss figure can be seen as a self-tapping screw is introduced in the inside of the cylindrical body, so that when the screw (7) is threaded, the annular junction section (6) of the extension (4) it breaks and causes it to move in the opposite direction to the screw (7), so that the cylindrical body (2) expands fixing the clip to the walls (8) of the hole.

The details, the shapes, the dimensions and others accessory elements, as well as the materials used in the manufacture of the centering clip 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 (4)

1. Centering clip (1), preferably of plastic material, comprising a substantially hollow cylindrical body (2) for the introduction of a screw element, which includes a plurality of ribs (3) arranged on the outer surface, including in the end that is located inside a wall or the like an internally hollow extension (4) of substantially truncated conical contour, characterized by the fact that the interior surface of said extension (4) is smooth and both the cylindrical body (2) ) as the extension in a single molded part, and due to the fact that the diameter of the inner hole of the extension is smaller than the diameter corresponding to the inner hole of the substantially cylindrical body (2). 2. Centering clip (1) according to claim 1, characterized in that the extension comprises an elongated cylindrical section that is located in the hollow inner part of the substantially cylindrical body. 3. Centering clip (1) according to claim 1, characterized in that the clip body and the extension are connected by the end of the cylindrical body (2) through an annular junction section (6) of reduced thickness. 4. Centering clip (1) according to claim 1, characterized in that the ribs (3) are located equidistant and transversely with respect to the cylindrical body (2), presenting a substantially arched contour and also being inclined with respect to the axis longitudinal of the cylindrical body (2).
