Abstract
Description
- The invention relates to a sail umbrella apt to be utilized on the beaches, in the gardens, in the bar-restaurants in the open and in the places by hawkers, therewith a place can be sheltered from the sun and rain.
- The umbrellas currently known have sizes which vary upon varying the use thereof and they can have a covering which can reach the size of few squared metres. Such covering can be circularly shaped, polygonally shaped and, in case of bigger umbrellas, they are usually rectangularly shaped with four stretching ribs. The known umbrellas have the covering structure similar to a dome or recalling the pyramidal shape. The bigger ones are frequently equipped, towards the ends of the stretching ribs, with hooking points whereon some cords are fastened to be anchored to the pedestal, to the floor or to the ground so as to prevent the umbrellas from lifting when they are stressed by the wind.
- Due to their shape and structure, the known umbrellas are hurriedly closed when the air from a stillness state begins to move, by making one afraid of gusts of wind. Under these conditions, one can see lifeguards running on the beach from one umbrella to the other to close them before the wind lifts them and detaches them from the pedestal supporting them, with the danger that they fall again violently against those present.
- The bigger umbrellas, the ones adopted by some bars, restaurants and hawkers, apart from the rope with pulley for lifting the collar, the ribs-counteribs and the covering canvas, have also auxiliary ropes for anchoring to the ground both because beneath them there can be products and goods which cannot easily be put back in protected rooms in short time, thus requiring that the umbrella be left open to protect the products for a prolonged time, and because the wind, even when low, exerts on the same considerable stresses which could cause the lifting thereof and, considering the weight, a disastrous fall-down.
- Hence, the need for the bigger umbrellas to have anchoring ropes and resistant points on the ground (floor) thereto anchoring said stabilizing ropes, with the nuisance, easily understandable, for the persons who have to move around them.
- Due to such drawbacks suspended umbrellas have been implemented, that is with the pole supported by a rigid structure with cantilevered arms. Such structures are bulky and very expensive. Each one is usually apt to support several umbrellas arranged therearound. In such embodiment solution each covering structure, in case of wind, can oscillate to discharge the air accumulations under its own covering canvas.
- However, the oscillations are so as to force the operators to close the umbrellas before the bumping of one into each other, due to the oscillating motion of the suspended coverings, causes the destruction thereof. Moreover, if such solution can be considered suitable for hotels and restaurants, and however in case of low wind, it cannot be adopted on the beaches since the plurality of required coverings would involve considerable costs and however it would force the lifeguards to close quickly the single coverings upon the approaching of windstorms, which otherwise would cause the destruction thereof.
- Such coverings are not suitable to be utilized by hawkers too, each thereof has his/her own available limited space which has to be uniformly protected by a single covering canvas.
- An object of the present invention is to implement a structure shaped like an umbrella with a single covering canvas, able to have different widths in order to cover reduced surfaces, as it is required on the beaches, and bigger surfaces up to the ones required by the hawkers.
- Another object of the invention is to implement a covering structure which could have a single supporting pole, in one case suitable to be supported by a pedestal, without requiring hooks or ropes for anchoring to the ground, in another case suitable to be supported by high structures thereto the supporting pole would be appended.
- Still another object is to implement a covering structure very resistant to the wind action, even when it is relatively strong, so as to suggest to close the covering only when the wind becomes intense.
- Finally, another object is to implement a covering structure the activation thereof, in order to bring it from the closed state to the open state and viceversa, is relatively simple and the operation thereof can be executed even by a single person.
- The invention which has allowed obtaining such results implements in a structure comprising:
- a supporting pole;
- a plurality of ribs converging onto a point of said pole;
- the covering canvas anchored to said ribs;
- means apt to bring the ribs from the closed state to the open state and viceversa, an activation rope or stay-rod connecting a point placed towards the end of a folding rib with a sliding point placed towards the pole top;
- a jib fastened to the covering canvas at the position of said folding rib, and connected to the activation stay-rod, being said jib destined to act as orienting rudder of the covering canvas, so that in case of wind the umbrella orients.
- The canvas upward folding, at the folding rib inflected by the activation stay rod, allows the continuous exhaust of the air which is pushed by the wind under the covering itself.
- Such structure results particularly advantageous since, independently from the wind direction, the covering orients so that its jib, acting as rudder, arranges in a direction parallel to the wind. Under such conditions the covering is stressed by the wind with two forces, one thereof pushes the umbrella towards the ground, the other one pushes the umbrella in the direction of the wind itself so that it bends until reaching the new equilibrium state, without exerting violent stresses and vibrations on the structure supporting the covering.
- Another advantage of the described structure derives from the fact that it does not require additional ropes anchoring to the ground (floor), therefore the space around the pole, when it is fastened to the ground, does not require additional anchoring.
- Another advantage derives from the fact that the exhaust of the air pushed under the covering canvas is continuous, therefore if the wind is constant, the covering does not oscillate, thus allowing to place such coverings even very near between them, as it is requested during summer on the beaches and in the places or streets wherein the hawkers' markets take place, without said coverings bump one into each other or damage mutually.
- Another advantage derives from the fact that the wind action compresses the canvas towards the ground, by averting the danger of detaching the umbrella from the seat supporting it and thus the dangerous fall-down thereof to the ground, thus allowing the users having many umbrellas to start closing them with much tranquillity.
- Other advantages will be evident, particularly to the persons skilled in the art, by reading the following detailed description referred to a practical preferred embodiment solution of the invention, reproduced by way of example only in the drawings of the enclosed figures, wherein:
- figure 1 is the front view of the umbrella in the closed state;
- figure 2 is the top perspective view of the umbrella in the open state;
- figure 3 is the top perspective view of the umbrella in the open working state, that is with a rib inflected upwards and with the orienting jib in the stretched state;
- figure 4 is the elevational side view of the umbrella of figure 3, with reproduced half covering and showing the air motion orienting the said covering;
- figure 5 is a different elevational side view of the umbrella of fig. 3;
- figure 6 is the elevational side view of the bearing structure of the umbrella in the open state and, with sketched lines, the inflected rib and the small rope causing the inflection thereof are designated.
- It is understood that the drawings are exemplary only, with the only aim at facilitating the comprehension of the invention, without being a limitation therefor.
Substantially, the invention consists in an umbrella therewith open spaces are sheltered mainly from the sun and the rain. It comprises a supportingpole 1, a plurality ofribs 21 converging onto apoint 3 of thepole 1 and to which the coveringcanvas 4 is anchored, means 5 apt to bring theribs 21 from the closed state, that is from the position wherein they are almost parallel to thepole 1 or however oriented towards the floor, to the open state wherein they spread the covering 4 to cover a space and protect it from the sun and the rain. - If further comprises an activation rope or stay-rod 6 connecting a
point 7 placed towards the end of arib 21 with asliding point 8, placed towards the top of thepole 1. Said stay-rod 6 is apt to determine the upward inflection of the saidrib 21. - Finally, it comprises an
orienting jib 9, fastened to the coveringcanvas 4 at therib 21 destined to inflect upwards and to the stay rod 6. Saidjib 9, when stretched, acts as orienting rudder of the covering, then it creates an almost vertical surface whereon the wind acts in order to change the orientation of the umbrella itself. - Such functional structure comprises the supporting
pole 1 characterized in that it is usually axially revolving on the means supporting it to facilitate the orientation of the umbrella when it is in the open state and in presence ofwind 10. Thering nut 3 or other equivalent means, thereto theribs 21 are hinged whereon the coveringcanvas 4 is fastened, is fastened onto saidpole 1, at an appropriate distance from the top thereof. Therefore, theribs 21 rotate on saidring nut 3 when they pass from the open state to the closed state and viceversa. - Said
pole 1, in the preferred embodiment solution in the case wherein the umbrella is used on the beach, is destined to couple on the lower side to supporting means on the ground, not reproduced in the drawings, thus it has a length appropriate for the purpose, usually around 200-230 centimetres. - In another embodiment solution the
pole 1 is coupled on the upper side to the supporting means, not reproduced in the drawings, for example to cantilever bars at 250-300 centimetres from the ground. In this solution the umbrella is widely used in bars and restaurants on the open. In this case, thepole 1 has a length suitable for receiving the sliding ring nut whereon, in the example of figure 6, thecounter-ribs 11 are hinged, or in another solution the inflection points wherefrom the stay-rods 5 emerge which stress theribs 21, towards themiddle 2 thereof, in order to pull them towards the open state or to release them towards the closed state. In thepole 1 themeans 15, thereto the stay-rods 5 are clamped which support the saidribs 21 in the open state, as well as the activation rope or stay rod 6 are placed. - The
ribs 21 are made of wood or metal and at least one thereof is able to inflect upwards to create the orienting rudder and the escape route of the air pushed under the umbrella itself, as reproduced in the figures 3, 4 and 5. - In the
pole 1, above thering nut 3 thereon theribs 21 are hinged thereto the coveringcanvas 4 is fastened, thesliding point 8 is placed theretowards theend 7 of the saidrib 21 itself destined to inflect upwards is pulled, as exemplified in the figures 3 and 4. - Said sliding
point 8 is placed at a level at least higher than the intersection point of the axis of thepole 1 with the line tangent to the rib to be inflected when it is in open position, but not inflected, with the tangent point on theattachment point 7 of the activation stay-rod 6, placed towards the end of the said rib to be inflected. - In this way, when the umbrella is in the open state, the pulling of the activation rope 6 determines the upward bending of the
rib 21 and not a decrease in its radius of curvature and thus not its downward bending. - Once surpassed the
sliding point 8, the activation rope 6 is leaning downwards in order to be grasped and activated by the user. Said rope 6 is suitable to be anchored in a stretched position onto thepole 1 in aclamping point 15 which can be reached by the user. - On the covering
canvas 4, at therib 21 destined to inflect, thejib 9 is placed, that is a voile fastened to the coveringcanvas 4 and, on the free side, coupled at least in some points to the activation stay-rod 6 in order to be brought and kept in a stretched configuration, particularly with thecorresponding rib 21 bent upwards. - The
orienting jib 9 is shaped so as to recall the triangular shape and, thus, it is so as to create a surface resistant to the wind, until arranging parallel thereto, by making the covering to rotate. - In the preferred embodiment solution the covering
canvas 4 has a prolonged shape, that is it recalls the rectangular shape. In this solution, then, the umbrella has fourribs 21, with an almost equal length between them. In presence ofwind 10, with therib 21 activated by the rope 6 in a position bent upwards, the umbrella assumes the configuration reproduced in the figures 3 and 4. In such state the orientingjib 9 causes the umbrella to rotate as long as the jib is oriented in the wind direction. - Furthermore, once reached such orientation, the covering 4 on the side therefrom the wind comes is stressed by compression, that is towards the floor, whereas on the opposite side the air under the
covering 4 comes out, as in the drawing exemplified in the figure 4, by making in this way the umbrella itself particularly stable. - During the implementation step, the implementation particulars could undergo wide variations, without altering the functional logic which is the basis of the invention defined by the following claims.
