Abstract

Folding device to facilitate the interlocking a rod or mast with helical end, of type used in beach umbrellas or any other element liable to be driven in a rotational terrain, characterized  essentially because it has a folding torsion rod (1) equipped with a bumper-like stop in its central third (4) or similar, while at its opposite end, it presents a second stop (5) preferably formed by an increase in its diameter, which is linked to a folding support (6), associated with a fixed support (8) linked to the mast (2) through a ball joint or shaft of rotation (7) incorporating at the same time a seat in the form of "U" (9) on which the rod (1) sits when it does not is in use, and a through hole (10) made in the mast (2) through which you can cross the rod (1) to place it in position  of work.

Description

Folding device to facilitate the interlocking of a rod or mast with helical end.

Technical field

The object of the present invention, as expressed in the statement of this specification, does reference to a device to facilitate the interlocking of a rod or mast with helical end, of the type used in beach umbrellas or any other cylindrical device liable to be driven into soft or sandy ground, by rotation.

Background of the invention

Normally, tall beach umbrellas adjustable are constituted by a first fixed mast whose end Sharp bottom is driven into the sand, inside which introduces a second movable mast vertically movable by the inside of the first one, which is the one that incorporates the system of rods with the fabric that constitutes the parasol itself saying.

In simpler models, there is a single mast of fixed height

Traditionally, to fix the mast, the user must support the sharp end in the sand and perform axial pressure on it so that it is embedded in it.

Such a device is written in the utility model with publication number 1019950.

However, if the sand is excessively compact or the user can develop enough strength physically, the mast may be badly nailed and therefore badly Fixed to the sand.

Some more evolved masts present their lower end, sharp and surrounded by a threaded fin helical (as a worm) integral to said end, so that when the user prints to the mast a movement of rotation, with relatively little effort, this is screwed into the sand moving down until it is firmly anchored in the same; to help the user, the mast usually incorporates some type of torsion rod that is normally placed in position horizontal through the mast through through holes horizontal especially dedicated to it.

Devices of this type are described in the utility models with publication number 1043410 and 1050992.

However, these devices have a problem, and that is that the torsion rod is an element independent and not permanently attached to the mast, so there is a risk that before, during or after use, this is lost, so that the mast equipped with helical termination would lose the ability to be easily screwed into the ground.

Description of the invention

In order to overcome these inconveniences, it has designed the new folding device for rod or mast with helical end, object of the present technical report.

Generally speaking, the present invention will be refers to a new device to facilitate interlocking of a rod or mast incorporating a linked torsion rod permanently to the mast, so that it cannot be lost in No circumstance.

In addition, it is designed so that, in a position concrete, can also serve as hanger.

The new device to facilitate the interlocking a rod or mast is constituted by a preferably cylindrical section rod, equipped with two stops, one in its central third consisting of a busty or similar that it will limit its movement on the one hand, and the other its opposite end, preferably formed by an increase in diameter of the rod, which will limit movement on the other side.

The rod is permanently linked to a 90º folding support, placed between the pin and the end of increased diameter; that way you can never get out of said support.

Also on the mast, a seat is arranged U-shaped, to immobilize the rod in position parallel to the mast, when it is not in use.

In work situation, the rod is in perpendicular position to the mast, through a hole intern practiced in it for that purpose, so that it stands out approximately the same length on both sides of the mast.

At rest, if partially removed the raised end of the rod, of the folding support, is It can also serve as a hanger.

The assembly of the novel rod is very simple; first, the rod is removed from its fixed seat; then, the folding support is rotated 90 ° until leaving the rod perpendicular to the mast and facing the through hole of the same; Finally, the rod is pushed against the mast, making that it goes through its through hole until its busty stop is in contact with the folding support.

Description of the drawings

In order to illustrate how much so far we have exposed, is accompanied by the present specification and forming an integral part of it, of a set of drawings in those that have been represented in a simplified and schematic way, a practical embodiment example only explanatory but not limiting, of the characteristics of the novel invention.

Figure 1 shows a profile view of a mast equipped with the new device.

Figures 2, 3 and 4 show three views in elevation in which the assembly process of the dipstick.

Figure 5 shows the rod placed in hanger mode

Description of a practical example

The new device to facilitate the interlocking a rod or mast with helical end, is constituted by a folding rod (1) of cylindrical section, endowed in its central third with a stud (4), while in its opposite end has an increase in diameter (5) that will make butt on the other side. The rod is permanently linked to a 90º folding support (6), which is located between the pin (4) and the end of increased diameter (5) so you can never get out of said support (6).

The folding support (6) rotates on a support fixed (8) attached to the mast (2) through a ball joint (7).

On the mast (2), a seat is arranged in "U" shape (9), in which the rod (1) sits when It is not in use.

Finally, the mast (2) has a hole through (10) through which the rod (1) is inserted to position it in working position.

They will be independent of the purpose of this invention the materials used in the manufacture of different elements that compose it, as well as the forms, dimensions and accessories that may present, and may be replaced by other technically equivalent ones, provided that no affect the essentiality of it or depart from the scope defined in the claims section.

Established the expressed concept, it is written to then the note of claims, thus synthesizing the news that you want to claim.

Claims (1)

1. Folding device to facilitate the interlocking of a rod or mast with a helical end, of the type used in beach umbrellas or in any other element capable of being driven in a rotational terrain, characterized essentially because it has a folding torsion rod (1 ) provided in its central third with a stop as a stud (4) or similar, while at its opposite end, it has a second stop (5) preferably formed by an increase in its diameter, which is linked to a support folding (6), associated with a fixed support (8) linked to the mast (2) through a kneecap or rotation axis (7) while incorporating a "U" shaped seat (9) in which seat the rod (1) when it is not in use, and a through hole (10) made in the mast (2) through which the rod (1) can pass through to place it in the working position.
