Description

Suction umbrella stick.

Introduction

The present invention relates to one of the main elements of a beach umbrella as is the stick that It sustains her. The umbrella itself is a feature umbrella normal in terms of shape design and opening procedure and close. However the support stick is characteristic very special since, thanks to the idea of this invention, it is liable to be introduced in the sand of the beach with a minimal effort that can be executed by anyone whatever your age or physical preparation. The umbrella stick is enter the sand deep enough to make it firmly attached to the ground without danger of overturning or movements untimely by gusts of wind or any other cause.

Sector of the technique to which the invention relates

The invention presented affects the Sector of Current necessities of life and specifically to the chapter of Objects for personal use. It also affects the Techniques Sector Various Industrialists directly affecting the industry of manufacture of articles and accessories for beach.

Background of the invention

There are numerous backgrounds in everything related to beach umbrellas which is natural to be the beach expansion one of the activities within reach of all economies including the most modest.

Thus, to cite some of the background, it they find the traditional umbrellas that sink into the sand with some effort, although depending on its size, and if not they dig deep enough, it is easy for tipping to occur Because of the wind. To avoid this, there are inventions that refer to additional parts that fit on top of the umbrella and with three or four braces that are anchored in the sand, the risk of falling is better ensured.

There are also umbrellas that are attached to the beach chairs, tables or sunbeds, being its stability very dependent on the weight of the person who is occupying the chair or the sunbed or the weight of objects placed on the table, apart that the size of these umbrellas is relatively small.

There are also many dice very profusely of concrete or any other heavy material, which are placed on the sand and receive the umbrella stick in a hole prepared for that purpose.

Anyway, you could cite more examples, although in any of them takes on very relevant value the ease with which the umbrella is placed in its final position to exercise its function.

It is evident that in any of the cases before cited the user must carry supplementary accessories or exercise an important effort to nail the umbrella in the sand.

Given these inconveniences have arisen new inventions that facilitate sunshade driving so that This operation is available to anyone performing a reduced effort This is the case of a complementary contraption of the umbrella that allows to make a hole in the sand for later Enter the stick of it. We can also cite the case of a kind of drill that is introduced into the sand by a twist continued to be exercised with the hands. Or the case of others more complicated gadgets than cranks and screws endless move a kind of plunger upward dislodging a certain amount of sand, however presenting the inconvenience that the sand easily enters the mechanism preventing its correct operation.

The inventor of the device here is presents, knowledgeable about the solutions available so far, has conceived a very simple and novel one that simplifies the drawbacks, it has the advantage that the umbrella stick it can be stuck in the sand with very little effort allowing for so much that the nailing operation is done by anyone who be your age or physical condition and with another very important advantage as is its easy manufacturing and low price that puts the device available to anyone.

Description of the invention

The present invention relates to a new stick of an umbrella, which is usually used on beaches, which presents the particularity that can be introduced in the beach sand with minimal effort, that is, that the operation nailing can be executed by anyone regardless of their age or physical condition

The stick consists of a metal tube of lightweight or plastic material of adequate strength, of a approximate length of one meter and an external diameter of about three centimeters, although these dimensions are approximate and have no Nothing to do with the principle of the invention.

The upper part of the stick is cut according to a plane perpendicular to the longitudinal axis of the tube that forms it and the lower part, that is to say the part destined to be introduced in the sand, is slightly sharp to facilitate driving.

In addition, in the aforementioned tube, which we will call principal, another tube is introduced, which we will call suction, of the same lightweight material, whose diameter outside is practically coincident with the inside diameter of the main tube but with enough play for the tube sucker can slide longitudinally, smoothly, over the main one

As for the ends of this tube suction, the one at the top is also cut according to a plane perpendicular to its longitudinal axis and that of the bottom It is completely closed by a glued or welded metal plug, or alternatively by a rubber, silicone or material plug Similary.

The result of this arrangement is that the tube suction, when moving longitudinally on the tube main, it functions as a true blower plunger or suction when the assembly is introduced in any fluid.

In our case, the objective of the invention is take advantage only of the effect of suction on a "fluid" Special as is the sand on the beach. Thus, being introduced a tube over the other, with the main slightly driven into the sand, proceed to pull up the suction tube at the same time that a slight downward pressure is exerted on the tube principal. The "suction pump" effect absorbs sand from the beach that goes into the hollow that is left in the main tube at the same time as this one is progressively penetrating the hole left by the evicted sand.

This process stops when, in the opinion of the user, enough depth has been reached in the dive, for which there are some indicator marks that indicate approximately that depth.

Once this process is finished, the operation is completed placing the umbrella inside the suction stick.

The figures and description of an embodiment preferred, which are included below, will help you understand better the operation of the invention.

Description of a preferred embodiment

Suction sunshade stick (1) (Figs. 1, 2 and 3) consisting of a beach umbrella stand designed for be stuck in the sand, deep enough to resist wind effects, with minimal effort executable by any person who, in an embodiment preferred by the inventor, It consists of a main tube (2) of cross-section in the form circular crown and a suction tube (3) whose section transversal is also a circular crown, with the particularity of that the outer diameter of the suction tube (3) is substantially equal to the inside diameter of the main tube (2) such that the longitudinal displacement of a tube with respect to the another because there is a slight slack between them.

The main tube (2) is open by its two ends presenting the lower end a sharp section (2.1) that facilitates its insertion in the sandy ground existing on the beaches Traditional The suction tube (3) is open for its part superior, since it is the one that should receive the umbrella stick (4) proper; on said upper edge it is coupled a handle (3.1) to facilitate handling of the assembly (1) in the moment of driving. This handle also has some protuberances that will function as a clothes hanger light

On the bottom is tight, being closed, either with the same tube material, or preferably with a plug (3.2) (Fig. 2) which, being very well adjusted, or even glued, to the body of said tube (3), also fits the inner surface of the main tube (2) to favor the effect suction plunger.

Under these conditions, the umbrella stick sucker (1), at the time of transport and first use, has the suction tube (3) fully inserted in the main tube (2) with the handle (3.1) butting with the upper end of the main tube or being very close to said edge (Fig. 3a) being able to dive slightly into the sand in a first phase as depicted in (Fig. 3a) by applying a force F1 towards down. In a second driving phase, represented in (Fig. 3b) and, (Fig. 3c), the user with one of his hands on the handle (3.1) pull up with force F2 while holding the tube main (2) with the other hand applying on it, downwards, a F1 force.

This process of action causes a suction and sand flow (5) into the main tube (2) as consequence of the "piston effect" caused by the movement relative of the suction tube (3) with its cap (3.1) inside of the main tube (2). In parallel, the main tube (2) can be easily move down occupying the empty space generated by The sucked sand.

The process ends when the user considers that the assembly (1) is sufficiently sunk in the sand (5) in whose moment you can proceed to insert the umbrella stick (4) inside the suction tube as hinted at in the (Fig. 3c). The height lock mechanism of the umbrella (4) on the suction stick (3) is not described as not being subject to this invention.

The inventor conceives, on the other hand, complement the characteristics of the main tube (2) recording in its lower part one, two, or more references that allow to know with a simple glance the depth of the driving.

As for the material in which they are manufactured the tubes can be any, either metallic or plastic, although preferably a light material will be chosen to facilitate the set transport. The material of the cap can be rubber, polyamide, silicone or similar.

The inventor also conceives the possibility of the main tube is provided with another handle equipped with several hangers to hang on them light clothes.

It is not considered necessary to make the content of this description for a subject matter expert can understand its scope and the advantages derived from the invention, as well as develop and implement the object of the same.

However, it should be understood that the invention has been described according to a preferred embodiment thereof, so which may be subject to change without implying any alteration of the basis of said invention, being able to affect such modifications to the shape, size and / or Manufacturing materials; that is, the terms in which it has remained Exposed this preferred description of the invention, should be always taken with a broad and non-limiting nature.
