Abstract

The present application provides a screwing element for threaded joining/attachment systems, independent of the threaded screwing element of the joining/attachment system, coupled at least partially to the external geometry of the threaded screwing element, comprising a coupling ring with an internal open geometry and one or more manual grip and/or rod elements on the external surface of the coupling ring. The coupling ring is coupled so as to substantially coincide with the external geometry of the threaded tightening element, the internal open geometry of the coupling ring enabling the tightening element to pass completely over the entire threaded tightening element. At the intermediate region of the bore formed by the internally open geometry of the coupling ring, there is provided at least one resilient abutment projection projecting from the surface of the internally open geometry of the coupling ring.

Description

Screwing element for a threaded joining/attachment system

Technical Field

The present invention relates to a screwing element coupled to a threaded system to perform, with the aid of said screwing element, a rotation action of the threaded element of the system to be screwed.

Technical Field

In a conventional manner, the installation of multiple elements necessitates the use of a thread system that enables the screwing of the threaded element onto a complementary thread of the target portion to achieve the attachment of the threaded element.

Conventionally, these thread systems use known tool devices, such as open-end or socket wrenches of a certain metric size, or monkey wrenches or parrot beak wrenches (water pump wrenches, rebar wrenches, water pipe wrenches) which enable the same wrench to be adapted to the metric size of the threaded element to be tightened.

On the tool side, such conventional screwing methods are limited when the threaded element to be screwed is connected to a conduit, pipe or the like, such as an "elastic" or flexible hose for a pipeline, by one of the ends of the threaded element. These threaded elements have an integral guide tube at one extremity of the threaded element and must be tightened against the equipment or guide tube to which it is desired to connect, these threaded elements hindering the use of wrenches inserted into the threaded element along the axis of rotation of the joining thread.

In these cases, which are also often accompanied by connecting positions that are difficult and inconvenient for the installer to access, it is necessary to use a tool that is easy to engage with the threaded tightening element and that can be positioned simply and efficiently and does not exceed the external grip size of the threaded element to be tightened.

There are nuts with wings, also called wing nuts, among the prior art, which enable manual screwing without the use of tools. The wings projecting from the outside of the threaded element to be tightened enable the installer to apply a greater torque with his hands, often achieving the attachment force required for the desired assembly, without requiring more tools.

A drawback of this system is that the wing nut has previously to be mounted on a standardized type of product, such as a flexible hose, so that there are different types of product depending on the type of threaded element and problems in terms of production and stocking due to the variability of the standard products.

On the other hand, separate elements are also known, coupled to the nut by one side, providing the nut with elements for gripping and leverage to achieve manual screwing. These elements can generally be coupled only on one side of the element and cannot be used in the configuration in which the threaded element is fitted with a pipe.

Therefore, there is a need for a solution that can maintain the invariance of standard products, which solution can facilitate the manual screwing of threaded elements without the need for tools.

SUMMERY OF THE UTILITY MODEL

The object of the present invention is to provide a screwing element for a threaded system that overcomes the above-mentioned drawbacks, presenting other advantages that will be described below.

Preliminarily and by way of clarification, the threaded joining/attachment system described herein refers to any joining or attachment assembly between a nut and a bolt, a male threaded connector and a female threaded connector, or between joining/attachment systems in which a threaded tightening element is threaded onto a complementary threaded element, for joining two elements, conduits, etc., and for fixing the position of one or more components.

In accordance with this purpose and with regard to the first aspect, the present invention is based on a screwing element for a threaded joining/attachment system, independent of the threaded screwing element of the joining/attachment system itself, coupled at least partially to the external geometry of the threaded screwing element.

Advantageously, the screwing element comprises:

-a coupling ring having an internally open geometry which engages so as to substantially coincide with an external geometry of the screwing element;

-one or more manual grip and/or rod elements on the outer surface of the coupling ring.

In this respect, advantageously, the internally open geometry of the coupling ring of the invention enables the screwing element to pass completely through the entire threaded screwing element.

It is also advantageous for the screwing element to have, at the intermediate region of the hole forming the internal open geometry of the coupling ring, at least one elastic abutment projection projecting from the surface of said internal open geometry of the coupling ring.

This configuration makes it possible to obtain a separate manual screwing element that can be coupled to a threaded screwing element, such as for example a nut coupled to a flexible pipe, so as to form an outer casing that fits on the external shape of the threaded screwing element, the screwing element having a gripping element that enables the screwing torque applied manually to be sufficient to satisfy the desired coupling.

The tightening element has a bore which substantially coincides with the bore of the screw-threaded tightening element, which enables the screw-threaded tightening element to pass through the tightening element despite the resistance of the plurality of elastic projections which, when overcome by the screw-threaded tightening element, are held in the opposite direction to the direction of insertion of the screw-threaded tightening element without the application of an external removal force.

The screwing element is used in installations with flexible pipe tubing or the like, wherein one end portion of the threaded screwing element is connected to the catheter and, in order to be able to use the screwing element as described herein, the threaded screwing element has to be pre-assembled; this use enables the manual screwing element to remain preassembled without having to worry about an undesired disconnection of the screwing element. In this way, it is possible to provide sets of flexible pipe-line on which the screwing elements are preassembled, so that they remain in the preassembled position, without any risk of inadvertently disassembling them and ready for installation, coupled to the threaded screwing elements, and then manually screwed without the need for the use of tools.

In a possible preferred embodiment of the invention, the grip and/or the rod element are formed by one or more lug portions, protrusions or geometries protruding from the outer surface of the coupling ring.

These configurations allow considerable torque to be applied manually without the need for additional tools, as the lug portions, the projections or different types of projections and/or geometries enable this, thereby significantly improving the time of assembly in complex locations, such as in installations with reduced space and/or difficult to access fixtures, such as for example water supply connections to faucets or toilet tanks, bidets and the like.

As an alternative to the above, the grip element and/or the rod element are formed by a rough, grooved, non-slip or similar outer surface.

As with the previous embodiments, these configurations enable better rotation of the threaded tightening element to be performed manually without the need for more tools, since roughness, grooves, anti-slip surfaces, etc. enable improved manual gripping of the threaded tightening element.

For the present invention, it is preferred to mount at least one elastic abutment projection on the inner side of the coupling ring, the wall of which has a sufficient expanding flexibility to allow the passage of the threaded screwing element through said projection by applying pressure, so as to pass the threaded screwing element through the internally open geometry of the screwing element.

This embodiment enables these internal projections to keep the threaded element accessible past the projections and to preserve the exit of the threaded element in the direction opposite to its entry direction.

According to a further preferred embodiment of the invention, the coupling ring has an internally open geometry corresponding to the hexagonal thread. This internal bore design option enables the screw element to be adapted to most threaded elements.

Also preferably, the screwing element is made of a composition of mainly plastic material. In this connection and more preferably, the plastic material of the screwing element corresponds to ABS plastic or polypropylene with glass fibers. Other compositions may also be used where they provide sufficient structural stability to enable rotational force to be applied to hold the internal shape of the screwing element in place and to transmit rotation of the screwing element to the screwing element, as well as to provide flexibility to the walls and internal projections of the screwing element.

This composition of the element makes it possible to manufacture a manual screwing element independent of the threaded element, which screwing element is less costly and gives the element considerable resistance, thus making it possible to safely perform the manual screwing action by exerting pressure on the lug portion or the like, as described above.

Detailed Description

In a preferred embodiment of the invention, and as depicted in fig. 1 to 3, the screwing element 10 is formed by a cylindrical coupling ring 11 having an internally open geometry 12 in the shape of a hexagonal nut to be coupled to the geometry of the outer side 21 of a threaded screwing element 20, in this case a hexagonal nut of a flexible pipe line 22.

As already mentioned, the screwing element 10, which is made entirely of ABS plastic in the present embodiment, but other combinations are also possible, and is in one piece, comprises two diametrically opposite lug parts as grip and/or rod elements 14, which are located on the outer surface 13 of the coupling ring 11.

In alternative embodiments, the geometry of the internal bore of the screwing element may be different to adapt to the shape of the threaded screwing element. Also alternatively, the grip and/or rod elements may be formed by grooves, non-slip surface treatments, ribs and/or geometries that enable manual grip and apply sufficient torque for the desired attachment function.

In a preferred embodiment, the screwing element 10 has a plurality of elastic projections 15 in the internal hole of the screwing element 10, which reduce the space of the internal open geometry 12, thus hindering the passage of the threaded element 20 through the hole formed by said internal open geometry 12. These protrusions 15 are located at the vertices of the open internal geometry 12 defining the hexagon and are aligned at the same depth of the channel formed by the holes.

With these projections 15, when inserting the tightening element 10 onto the hexagonal nut of the flexible tubing 22, in order to fully enter the hexagonal nut of the flexible tubing 22, it is necessary to press the tightening element 10 at a point of depth where the projections 15 of the tightening element 10 are located, so that when the hexagonal nut of the flexible tubing 22 is inside the tightening element 10, the tightening element 10 will not be accidentally removed, and the tightening element 10 will always be coupled to the flexible tubing 22, ready for installation without tools.

While reference has been made to a particular embodiment of the invention, it is apparent to a person skilled in the art that the screwing element for a threaded joint/attachment system described herein is susceptible to various modifications and adaptations, and that all the above details can be substituted by other technically equivalent ones, without departing from the scope of protection defined by the appended claims.
