FOLDING UMBRELLA WITH EASY ANCHORING TELESCOPIC POLE

TECHNIQUE SECTOR

The present invention is framed within the sector of technology and industrial production, while it consists of an innovative umbrella for sun protection composed of a folding and telescopic mechanism for easy anchoring. With regard to the application of the invention, it is specially designed for use in the tourism sector.

BACKGROUND OF THE INVENTION

As of the date of this proposal, and in reference to the current state of the art, it should be noted that the applicant researchers are unaware of the existence of any other invention that presents technical, structural or functional characteristics that are similar to those collected. in the present invention.

Umbrellas fulfill the main function of offering shade during sunny hours and protecting us from direct exposure in bathing, leisure and private use areas. There are different types of these mechanisms that are presented on the market in various sizes and shapes, most of which can be easily purchased in commercial areas.

However, there are two problems that sand-anchored umbrellas traditionally face. On the one hand, it has been detected that by having the support pole in the center of the fold of the umbrella, the shade surface provided by these products is not fully used during the hours in which the Sun reaches its zenith. And, on the other hand, it is known that the biggest problem these systems face is exposure to strong gusts of wind that cause them to be thrown from their anchorage area frequently.

With regard to the first of the mentioned problems, some inventors have opted to offer umbrellas or parasols that have the folding support axis on one of its sides, leaving the parasol suspended, with this solution having as its main problem the weight of the structure and the difficulty of being transported to bathing areas. Likewise, the problems caused by the wind have been studied by other researchers who have developed devices that allow anchoring or ballasting to the ground, and whose main On the other hand, its excessive weight or the need to make efforts to anchor it to the ground, which makes its application difficult for people with difficulties in carrying out sudden physical exercises.

Below are some of the most relevant examples found that are related to the device described in this report.

Patent ES2633039B2 entitled "Foldable beach umbrella with improved anchorage" shows a prototype of a conventional umbrella that has an alternative anchorage made up of a propeller and a platform that is buried in the sand to give the umbrella greater resistance to gusts of wind. Unlike the previous one, the present invention has an elliptical opening umbrella that offers a larger shade surface and an anchoring system through a telescopic worm mechanism, which facilitates its fixing without the need to bend down and make extra efforts to bury the umbrella. medium.

Utility model ES1166008U entitled "Umbrella” refers to a high-resistance parasol, which incorporates a handle with two deployable handles in the middle area of the anchor rod that facilitate turning and insertion into the ground to fix the umbrella. Despite the fact that it is a device that improves the anchoring of conventional umbrellas, at no time is reference made to the possibility of using an elliptical umbrella and a telescopic support whose threaded anchoring is favored by the use of a screw without end.

The utility model ES1034916U entitled "Improved umbrella holder" refers to a pointed device that is attached to the umbrella pole at its lower end, equipped with a wide helix that is used to facilitate screwing and sinking in sandy terrain. In this case, although it is an element that facilitates anchoring in low-consistency terrain, the device presented is understood as a complement to the stem of the umbrella and is not comparable with the telescopic system object of this invention.

Patent ES2666874A1 entitled "Device for holding umbrella poles or similar structures, made up of a support with a built-in motor and tools for its penetration and fixing on various surfaces", shows an innovative system capable of easily anchoring umbrellas in any The main difference with the present invention is found in the motorized system that requires being connected to the electrical network or another source of energy for its use, for this reason, it does not they are comparable.

Utility model CN211747453U entitled "Beach umbrella fixing device” refers to a removable fastening device that can be incorporated into the stem of the umbrella to facilitate its anchoring on sandy ground. The system described, although it facilitates anchoring by screwing, It consists of an independent piece that is attached to the main structure, so it is not comparable with the easily anchored telescopic pole described in the present invention.

Patent WO2016120036A1 entitled "Beach umbrella" describes a new prototype of a removable umbrella, easy to anchor and long-lasting. Unlike the previous one, the present invention describes an elliptical umbrella designed to make the most of the shading produced, as well as a stem telescopic with easy anchoring and threaded with the help of a crank through a worm mechanism.

Utility model CN203646658U entitled "Beach umbrella" consists of an innovative beach umbrella prototype that improves the performance and coverage of conventional umbrellas, by means of an umbrella suspended on a telescopic folding mechanism. Unlike the previous one, the patent that is the subject of this invention, consists of a folding elliptical umbrella, easy to pick up and that incorporates a telescopic rod that allows its anchoring by means of a crank and worm mechanism, thus avoiding overstressing when driving it into sandy ground.

Utility model CN203692724U titled "Lifting type beach umbrella” shows a lifting type beach umbrella, which rises and falls along the main stem by means of a gear mechanism. For this vertical movement, it uses a connecting rod that saves efforts and has good stability The present invention differs from the previous one in that the mechanism that includes the crank is used to anchor the support to the ground, facilitating the threading by means of an endless screw that advances with the turn of the crank, in addition, the The umbrella surface of the umbrella is elliptical and has a slotted spherical pair mechanism to search for inclination in light of the solar movement.

Patent WO0160193A1 entitled "Non-spherical beach umbrella with an eccentric support, moving by horizontal rotation" describes a decentralized umbrella prototype, which differs from traditional umbrellas by offering more shade by having the holding frame at one end. Although the elliptical umbrella object of this invention is also decentered to improve the ability to offer shade, both the folding system, as well as the inclination mechanism by means of a slotted spherical pair and the anchoring mechanism by means of a threaded telescopic pole with the help of a crank, are not comparable with the aforementioned invention.

Utility model CN205757684U entitled "Spring telescopic umbrella pole for sandbeach umbrella" describes a telescopic pole specially designed to adjust the height of the umbrella of beach umbrellas. Unlike the previous one, the telescopic pole proposed in the present invention allows easy screwing from the stem to the sand by means of the aforementioned crank-worm mechanism.In addition, the utility model does not describe the shape of the umbrella at any time, so they are not comparable.

Utility model CN207100762U entitled "Eccentric umbrella" describes an umbrella that has its opening axis in one of the foci of the ellipse, achieving a greater shading surface by decentralizing the clamping frame. The umbrella object of the present invention can also be It is decentralized and has an elliptical shape, however, it is not comparable with the previous one in that it has a grooved spherical pair mechanism for its inclination, the folding system by telescopic collection of the rods is different and also includes a holding stick Equipped with an innovative anchoring system on sandy ground by means of a telescopic endless screw.

The ITBN990010U1 patent entitled "Bastone per ombrellone da spiaggia a punta elicoidale con motore eletrico e battery ricaricabile” refers to an umbrella pole that allows easy driving into sandy soils with the help of an electric motor. The main difference with the aforementioned system is that the telescopic pole proposed in the umbrella that is the object of this invention is not motorized and is anchored manually, furthermore, in no case does the mentioned patent describe the geometry of the umbrella that is supported.

Consequently, there is currently no umbrella prototype that meets the conditions of the present invention or is included among its attributions.

EXPLANATION OF THE INVENTION

Folding umbrella with a telescopic pole for easy anchoring, whose characteristic parts are: the umbrella pole made up of two pieces, a lower bar that consists of an endless screw mechanism for anchoring on preferably sandy or low-consistency terrain and a telescopic upper bar that supports the parasol with elliptical geometry that has several fixing positions. Said bars of the system that make up the umbrella object of this invention are adjusted to each other by means of a preferably threaded fit in which the upper bar is inserted into the lower one, although it can be the other way around. This adjustment can also be made using a system whereby the upper bar fits into the lower one and is retained by means of a bolt.

The lower bar consists of an extensible endless screw mechanism to facilitate driving into the ground. For this, said system consists of a crank that, by turning it, allows the umbrella pole to move forward or backward, which slides through a preferably metallic aluminum tube. The advance of the umbrella pole in its penetration into the ground occurs with a combination of movements, one of extension in the direction of the axis and another of rotation to facilitate screwing and anchoring to the ground. In turn, the umbrella pole is preferably finished with a conical point, and has an external thread that facilitates threading and improves its adherence to the ground once inserted. The thread pitch of the endless screw does not have to coincide with the ground anchor thread. The system is designed in turn so that the threaded part that is anchored with the help of turning the crank in the worm mechanism penetrates the ground to an approximate depth of no less than 20 centimetres. This lower bar is capable of incorporating a brush that allows cleaning the sand from the endless screw when it is retracted.

The telescopic upper bar consists of an extendable mechanism that allows the height of the umbrella to be set and can be adjusted according to the sun's position and user preferences. Said upper bar is inserted, preferably, by screwing one of its ends into the lower bar to join the two pieces that make up the pole of the umbrella. For its part, the other end of the upper bar consists of a grooved spherical pair mechanism that allows positioning the inclination of the parasol at different angles, depending on the sun's position to increase the shading surface. Said spherical torque mechanism may have a butterfly screw to improve its fixation and avoid possible movements. The inclination mechanism preferably has inclination positions of 0, 30, 60 and 90 degrees with respect to the ground normal, although it can be designed for other inclinations depending on the geographical latitude. It can also be conceived as a spherical pair without slots, so that its position can be fixed at any angle of inclination by means of a clamping screw or the like.

The sun protection fabric unfolds in the form of a fan with the help of rods telescopic forming a final elliptical surface. To maintain this geometry, once the parasol is unfolded, it is hooked at its ends by means of magnets, although button, zipper or hook fixing systems, among others, are also possible. The telescopic rods can be metallic or fiberglass, carbon or basalt, among other possibilities, with the ultimate goal of being slightly flexible to avoid cracking under the action of strong gusts of wind. The tips of these rods do not protrude from the perimeter of the parasol and have a rounded finish to avoid accidents. The umbrella fabric, in turn, can be the usual mesh fabric that allows the passage of some solar radiation and a percentage of the incident wind, so as to reduce the pressure or suction that the wind can exert on the unfolded umbrella. On the other hand, photovoltaic fabric can also be used to take advantage of the incident energy and incorporate a USB output device to charge mobile phones or other devices, in the latter case, if an electrical energy storage battery is incorporated, it should be located on the bar bottom to balance the weight of the parasol and improve its fixation to the ground.

The assembly sequence of the umbrella, once all the component parts have been extracted from the cover, would be as follows. First, the lower bar of the parasol is nailed to the ground, for example by rotating it around its axis in order to sink it easily. Next, the crank is rotated so that the extensible pole, through the endless screw mechanism, advances in the direction of the axis of the bar, screwing itself into the ground. Then, the upper telescopic bar is placed, fitting the end prepared for it by means of threading or the like in the lower bar driven into the ground. Immediately afterwards, the telescopic upper bar is deployed to the desired height. Subsequently, the umbrella cloth that makes up the elliptical geometry umbrella is extended until it is completely unfolded, to finally position it at the desired inclination and fix it with the help of the grooved spherical torque mechanism located at the other end of the upper bar. telescopic.

To facilitate the collection of the umbrella, it would be useful to use a fabric cover that allows the umbrella device to be stored folded. Said cover can be of different geometries and incorporate pockets and accessories. In addition, it would be convenient for it to incorporate a strap or handle for greater comfort in transport, with enough clearance to be able to be carried on the shoulder or in the hand.

The main advantages of said parasol compared to others currently existing are its good stability as it is easily anchored to the ground by means of the endless screw mechanism and its larger shading surface due to the elliptical geometry of the parasol. The system using the turn of the crank to advance the stick into the ground saves efforts and prevents people from having to bend down to dig a hole to bury the bottom bar. In addition, being a threaded bar, the shaft of the stick anchored to the ground has good adhesion and greater resistance to being removed under strong gusts of wind. The height-adjustable telescopic upper bar allows you to set its position depending on the user and the solar position. With regard to the elliptical surface that makes up the parasol, by having the support bar located in one of the sources of the ellipse, it allows gaining in shading surface and more easily spreading items such as towels in the shaded area. This fabric that makes up the parasol can be adjusted in inclination as has been commented with the help of a slotted spherical torque mechanism that is secured in its position with the help of a butterfly screw or the like. Finally, it is possible that the drop-down fabric that makes up this elliptical parasol is made with photovoltaic fabric to generate electricity in direct current, incorporating a USB outlet in the telescopic upper bar that allows charging mobile devices or similar.

PREFERRED EMBODIMENT OF THE INVENTION

Regarding the technical problem and possible industrial application to which the present invention tries to respond, it focuses on the development of an innovative system that allows the umbrella pole to be nailed and anchored to the ground easily and reducing the effort used for it. In addition, it is also intended by incorporating an elliptical parasol, to achieve a greater shading surface that allows better use of the space under the parasol, being able to regulate the inclination and fixing height of the parasol.

Without being of a limiting nature, a specific embodiment of the present invention is described below.

The lower bar that makes up the umbrella pole is nailed into sandy or low-consistency ground, it is done by exerting a rotating movement on the axis and pressing on the ground until it is driven in sufficiently with the help of the frustoconical point where it ends. the end of the bar in contact with the ground. Next, by turning the crank and with the help of the endless screw mechanism, the lower bar contained in the metal tube is penetrated and screwed into the ground up to the desired depth.

Subsequently, the upper bar is placed, which is threaded into the lower bar, adjusting perfectly. The telescopic system of this upper bar allows you to regulate the height of the umbrella and fix its position based on the solar height.

In a next step, the fabric that makes up the elliptical parasol geometry is extended until the parasol is fully unfolded. This umbrella cloth can be of a dense mesh in a minimum percentage of 85% or be made up of a totally or partially photovoltaic cloth to generate electricity in direct current. In the latter case, it is not recommended to use parasol inclinations greater than 30° in windy areas, to avoid the possible sail effect that facilitates the removal of the parasol from the ground.

Finally, the inclination at which it is desired to place the parasol is regulated with the help of a slotted spherical torque mechanism and its fixing by means of a butterfly screw or the like. This inclination can go from 0° to 90°, unlike traditional umbrellas umbrella-shaped whose inclination range normally ranges from 0° to 45°.
