Description

Secured umbrella vis-à-vis the important winds.

The invention relates to an umbrella provided with means to prevent it from flying away and / or that its cap turns when the umbrella is exposed to too much wind.

BACKGROUND OF THE INVENTION

In general, an umbrella has a vertical shaft coinciding with its axis of revolution, and which is held by a base resting on the ground and in which the end of this shaft is engaged. This vertical shaft carries a cap comprising a piece of conical fabric which is supported by a set of branches of the umbrella.

Each branch has one end hinged to the top of the barrel Extremists ^¬ moth-eaten to pivot in a plane contained ing the shank and the leg, and the other end that is free. Additionally, a whale cooperating with each arm having one end hinged to a central portion of the branch, and its other end ar ^¬ ticulée to a slide which slides along the shaft.

The conical fabric piece is carried by the dif ^¬ annuities branches that are regularly distributed around the shaft carrying them, and the movement of the slide vertically along the central shaft which surrounds allows to open and close the cap depending on whether this slider is placed in the up position or in the low position.

The central shaft is also equipped with a locking system of the slide in the high position, which keeps the sunshade open. The closure of the umbrella is obtained by unlocking the slide and lowering it, this lowering causing the lowering of the whales and branches. When a too strong wind rushes under such an umbrella, its cap can turn, that is to say, invert, and / or the whole umbrella can fly and go to damage external elements.

The FR2952280 discloses a system for immobilizing the slider having a pawl which is unlocked to release the slide as soon as the former ^¬ Tremite bottom of the central shaft is no longer resting on the ground, that is to say from that the parasol begins to sink.

If the umbrella is lifted, the slider is automatically unlocked and drops to close the umbrella, thereby eliminating any risk of the parasol flying off and / or damage.

However, the arrangement described herein is relatively complex to implement since it requires the integration of a series of mecha nical ^¬ components 1 inside the drum which is to be further impe ^¬ tubular rativement for receive these internal components.

OBJECT OF THE INVENTION

The object of the invention is to propose a solution to remedy this drawback.

SUMMARY OF THE INVENTION

For this purpose, the subject of the invention is a parasol comprising a barrel carrying a cap and a slurry ^¬ bucket sliding along the barrel between a high position for holding the open cap and a low position corresponding to the closure of the cap, the barrel having a bore under the slide when it is placed in the up position, a pin intended to be inserted engaged in this drilling to lock the slide posi ^¬ tion high so as to keep the umbrella open, characterized in that the drilling has an orientation ^¬ tion relative to the axis of the barrel is oblique, and means of return the pin down in case of wind tending to lift the umbrella.

With this arrangement, when a gust of wind rushes under the hood of the umbrella, it causes a rise of the umbrella which causes by itself the release of the locking pin of the slide. After the first burst, the parasol is therefore automatically closes ^¬.

The invention also relates to a sunshade as defined above, wherein the return means comprise a cord attached to the pin being agen ^¬ cated to pull the pin down in case of sou ^¬ lifting the barrel of the umbrella or when lifting the slider relative to the drum.

The parasol 1 according to the invention which is identified by 1 in Figure 1 comprises a central shaft 2 having its ex ^¬ lower end engaged in a base 3 which is here a room resting on the ground while being massive enough to hold the drum 2 vertical.

This umbrella has a series of branches 4 each having a central upper end hinged to the upper end of the barrel 2 and a lower peripheral end which is free. A whale 6 cooperates with each leg having a top end articu ^¬ Lee in a central portion of the corresponding branch, and a bottom end articulated to a slide 7 which surrounds the central drum 2 in being able to slide along it .

The different branches and the different ba ^¬ are thus regularly distributed around the central shaft, and the various branches carry a generally conical piece of tissue, not shown in the figures, this part being secured to each branch, for example by points seams.

As shown in Figure 2, the slider 7 to the ^¬ which are hinged the bottom ends of dif ^¬ annuities whales 6 has a general shape of revolution, and it can be locked in the raised position by a pin 8 passing through the central drum 2 at a drilling Réali ^¬ se specifically for this purpose. In the example of fi ^¬ figures, the central shaft 2 is a barrel in solid wood, but it may as well be a barrel in tubu- lar type steel. The bore 10 receiving the locking pin 8 of the slider 7 is oriented obliquely with respect to the main axis of the central shaft 2, instead of being oriented perpendicularly to this central axis, and the pin 8 is engaged by the bottom end of this blocking hole.

When the pin 8 is in place, as in Figure 2, its free end protruding beyond the shaft 2 is at its highest position, and this pin 8 is held in position by the slider 7 which is then supported on the free end of the pin 8. In other words, the friction forces resulting from the contact of the support of the slider 7 on the free end of the pin 8 ensure the maintenance of the assembly.

As can be seen in FIG. 2, the central shaft may not have a single through-hole intended to receive the pin, but several holes 10-13 having different inclinations, to adjust the sensitivity of the automatic closing of the sunshade with respect to the intensity of the wind.

The parasol according to the invention further comprises two cords or cables, identified by 15 and 16, and which ^re¬¬act respectively: on the one hand the slider 7 to the ex ^¬ tremity of the pin 8 which is its lower end when this pin is in place; and on the other hand the lower end of the pin 8 to a lower element capable of exerting a tensile force on these rope ^¬ letters in case of strong wind.

As seen in Figure 2, the cord 15 has one end connected to a screw eyelet 17 to a bottom face of the slide 7, and has its other end re ^¬ linked to an eyelet 18 constituting the bottom end of the pin 8 and constituting the termination of this extreme low ^¬ . This cord 15 has, when the gou ^¬ sacking 8 is engaged, sufficient slack to allow the exit of the pin 8 of the housing 10.

In the case of Figures 1 and 3, the lower end of the lower cord 16 is very substantially ten ^¬ due by being fixed directly to the base 3 which rests on the ground and wherein the lower part of the shaft 2 is enga ^¬ gée for keep this shaft 2 vertical.

In the event of a gust of wind engulfing under the hood of the open parasol, it tends to rise as a whole, the shaft 2 then sliding vertically in the base 3. At this stage, the traction undergone by the cord 16 due to the rise of the parasol pulls the pin 8 from its housing, thereby causing the descent of the slider 7, that is to say the gradual closure of the umbrella, until its shaft 2 comes back in contact with the bottom of the base 3.

If despite the gradual closure of the canvas, the umbrella continues to rise under the effect of wind, the cord 15 is then stretched, in the extension of the cord 16, to retain the umbrella by its slide. This causes the closure of the umbrella to be accentuated, until it no longer has enough hold in the wind and falls back, until its shank 2 comes into contact with the bottom of the base 3.

The different holes 10-13 in which can be engaged the pin 8 are used to adjust the sensi ^¬ bility of the umbrella to the wind under the effect of a gust causing the lifting of the slider 7, the pin 8 is removed if faster than she is engaged in a highly inclined hole, that is to say a per ^{¬ ¬} drilling forming an angle all the weaker with the central axis of the barrel 2.

In the example of Figure 4, the lower end of the cord 16 is attached to a fixed element which is here a ballast bag (sand or earth) 18 resting directly ^¬ on the floor 19, the lower end of the barrel 2 being here directly planted in the ground

There are two possible cases of operation:

The normal case of a possible vertical rise of the entire umbrella under the effect of wind, in which case the operation is the same as for Figures 1 and 3.

The abnormal case of impossibility of vertical rise of the whole parasol (for example by too much ^¬ of the barrel 2 in the soil, in this case, when the parasol is exposed to a gust of wind, it ^¬ evokes first a large opening of the cap to lift the slider 7 so as to release the locking pin 8 which falls from its own weight. If the wind continues to blow after the fall of the pin 8, it may not to provoke the overturning of the cap, that is to say its inversion: in this case, the slider 7 is held firmly by the cords 15 and 16 which are then stretched: thanks to them, the grout ^¬ bucket 7 can not go too high. when the wind ^¬ fai blit, the slide can then spontaneously down to the cap closes.

In the case of Figure 5, the cord 16 has its lower end attached to a table 21 which is itself even fixed to the floor 19, the barrel 2 being for him, there ^aus¬¬ , fixed to the ground 19 being planted therein.

The behavior of the system in the case of FIG. 5 is similar to that of the case of FIG. 4: after extraction of the pin 8, the cords 15 and 16 are taut to oppose a too great ascent of the slider 7 while the level of wind did not bais ^¬ se.

In the example of Figure 6, (the shaft 2 can not mount vertically, either by deliberately locking by locking screw 20, or by constituting a parasol crank deployment) it is simply a counter weight ^¬ 17 is set at the low end of the rope ^¬ lette bottom 16. When gust of wind under the fairing of the umbrella, this cap is penny ^¬ up to open a little more, which raises the bucket 7 coulis- to cause the pin 8 to fall, which is further pulled down by the counterweight 17. Once the pin 8 is out of its bore, the two cords 15 and 16 are tensioned together against the slider 7, so that the counterweight 17 pulls down this slider so as to further facilitate the closure of the cap.

Generally speaking, in the examples of fi- gures, we used two cords 15 and 16 by ^¬ which the slider 7 is connected to a lower element capable of exerting a pulling force downwards during ^¬ that a gust of wind rushes under the headdress.
