Description

DESCRIPTION "Umbrella"
[0001] The present invention relates to an umbrella, and in particular an umbrella with automatic opening-closing, by a special movement system.
[0002] Making umbrellas or beach umbrellas provided with automatic opening/closing mechanisms, for example provided with spring systems that facilitate in particular the operation for opening the umbrella, is known in the art .
[0003] Such umbrellas of the prior art, however, exhibit several disadvantages, as they are not easy to use and often require the manual closing of the covering. Moreover, there are systems for opening-closing umbrellas by handles or something else, but also these are not very practical to use. In fact, the closing operation often is not much easy since the umbrella, during the closing movement, closes about the central shaft, with the risk of interfering with or hitting the user. [0004] The problem of the present invention is to provide an umbrella which should solve the disadvantages mentioned with reference to the prior art. [0005] Such disadvantages are solved by an umbrella in accordance with claim 1. [0006] Further embodiments of the umbrella according to the invention are described in the following claims.
[0007] Further features and the advantages of the present invention will appear more clearly from the following description of preferred non-limiting embodiments thereof, wherein :
[0008] figure 1 shows a front view of an umbrella, in an open configuration, according to an embodiment of the present invention; x
[0009] figure 2 shows a front view of the umbrella of figure 1, in a closed configuration;
[0010] figure 3 shows a perspective, partial section view of a detail of the umbrella of figure 1;
[0011] figure 4 shows a further section view of a detail of the umbrella of figure 1; [0012] figure 5 shows a further section view of a detail of figure 1;
[0013] figure 6 shows an enlarged view of detail VI of figure 1 ;
[0014] figure 7 shows an enlarged view of detail VII of figure 1.
[0015] Elements or parts of elements in common between the embodiments described below are referred to with the same reference numerals .
[0016] With reference to the above figures, reference numeral 4 globally denotes an umbrella; the term umbrella must be understood in non-limiting terms and therefore, the umbrella may have various sizes, even though it is especially indicated to be used as garden umbrella, beach umbrella and the like. [0017] Umbrella 4 comprises a shaft or case 200, directed along a prevailing direction X, a plurality of sticks 400 suitable for supporting a covering sheet 502 and a base 900 securable to the ground. * [0018] Said, sticks 400, preferably at a moving end 404, are suitable for supporting said sheet 502.
[0019] The sticks may consist of a single piece or of multiple pieces with telescopic or folding extensibility. According to a preferred embodiment, the sticks comprise a sleeve or staff outer tubing 402 and a stem or inner telescopic staff 403 sliding into sleeve 402.
[0020] According to an embodiment, umbrella 4 advantageously comprises a stick movement unit 300 suitable for allowing an opening and closing movement of the sticks, said movement preferably being a rotary- translatory movement. Advantageously, said movement unit is operatively connected to motor means 102 for allowing the umbrella opening/closing.
[0021] The umbrella comprises a support staff 699, preferably contained into the sleeve or shaft 200, suitable for allowing a movement, along the prevailing extension X, for opening and closing the umbrella. [0022] According to an embodiment, said movement unit 300 comprises a threaded staff or- control screw 700 that also acts as support staff 699. [0023] The umbrella is provided with a covering cap 100 provided, at outlet zones of the sticks, with hinged tongues 101 for ensuring the umbrella protection from water. [0024] Advantageously, the umbrella is provided with motor means, such as an electrical motor for example driven by DC, AC or even by energy produced by solar cells suitably placed on any portion of the umbrella. According to an embodiment, said electrical motor is arranged into the shaft or, according to a preferred embodiment, on top of the umbrella.
[0025] According to further embodiments, the motor means are of the oil-pressure or pneumatic type so as to move the umbrella itself in opening and closing without manual effort. [0026] According to an embodiment, sheet 502 is below the sticks but another construction solution provides for the arrangement of sheet 502 both onto the sticks and in a version with side connection of the sheet to sticks 400. [0027] According . to an embodiment, said threaded staff 700 is associated by engaging to a nut screw 301 that can axially slide on the staff itself.
[0028] Nut screw 301 is integral in translation with a support plate 306 to which the sticks are hinged through hinges 408 and 409. [0029] The support plate 306 preferably slides on sliding guides 800, arranged along said prevailing direction X. The sliding guides 800 are preferably contained in said sleeve or shaft 200. [0030] Nut screw 301 is supported by bearings 303, 304 and supports an electro-magnetic brake 305. The electromagnetic brake 305, when actuated, makes the nut screw 301 integral with plate 306.
[0031] According to an embodiment, the sticks comprise an inner screw 405 on which a sliding block 406, contained inside sleeve 402, engages. Block 406 is integral in translation with stem 403 so as to allow a translation movement of stem 403 and in particular of end 404 that is constrained to sheet 502. [0032] The inner screw 405 is supported by bearings 407 and is integral in rotation with a clutch 401 that ends with a friction wheel 410.
[0033] The umbrella comprises a plate 311 integral in rotation with the motor means 102. Plate 311 is integrally associated to a sliding plate 310 suitable for interfacing by contact with said friction wheels 410 so as to transmit the rotational motion of the motor means to the stems.
[0034] The umbrella comprises a driving joint 315 that connects the drive shaft of the motor means to the movement unit 300, for example to the threaded staff 700. Thrust means 313, for example helical springs, and bearings, such as axial 314 and radial 312 bearings, are advantageously inserted between joint 315 and plate 311. [0035] The elastic means 313 advantageously influence the sliding surface 310 in abutment against the friction wheels 410 so as to ensure a friction force sufficient for transmitting the rotational motion from motor 102 to stems 403 of sticks 400. [0036] According to an embodiment, the motor means are integral with a locking plate l316.
[0037] Preferably, umbrella 4 comprises a stick guiding stop 415 that allows maintaining the sticks in equidistant position, also performing the task of giving a counter-thrust to the stick, such as to allow the best adhesion of the screw connecting wheel 410 to the sliding surface 310.
[0038] Advantageously, the umbrella comprises a sheet tensioning plate 500, preferably sliding axially on said support staff 699 or threaded staff 700; a threaded bush or nut screw 503 is inserted- between the plate and the threaded staff 700 so as to engage with the threading of the staff itself.
[0039] The plate is preferably connected to return or tensioning springs 501 that are connected to sheet 500 by eyelets, so as to pre-tension the sheet, constraining the sheet to the vertical movement of plate 500. [0040] The movement of plate 311 through the threaded staff 700 allows the actuation of the telescopic sticks of the umbrella through wheels 410, in turn connected to the inner screw 405 through clutch 401.
[0041] The telescopic movement of the sticks that support the umbrella sheet is obtained through the connection of the staff inner screw 405 with the block sliding on screw 406 arranged into the staff outer tubing 402. [0042] According to a further embodiment of the present invention, the movement along the prevailing direction X of said movement unit 300 can be ensured, in place of the control screw or threaded staff 700, by cables, with or without reel for the winding thereof, intended for the vertical pulling of plate 306"χ on the support guides 800. [0043] According to a further embodiment of the present invention, said movement unit 300, in replacement of the control screw or threaded staff 700, comprises a rack staff, associated to a gear controlled by said motor means, for example positioned as desired, for transforming the rotational motion into translatory motion from the bottom upwards, and vice versa, of plate 306 on the support guides 800. [0044] According to a further embodiment of the present invention, said movement unit 300 comprises an actuator, consisting of a motor with telescopic stem, in replacement of the control screw 700, intended for the vertical translation movement of plate 306 on the support guides 800. [0045] The above embodiments . therefore allow simplifying the stick movement and translation unit 300. [0046] Moreover, according to a further embodiment, in said stick movement unit wheels 410, which control the inner screws of the sticks, can be replaced with other solutions with gears, cables, with or without reels for the winding thereof, or with electrical motors for each stick.
[0047] The operation of an umbrella according to the present invention will now be described. [0048] One of the innovative aspects of the present finding consists in that the umbrella is of the foldaway type, that is, the sticks and the sheet, which traditionally make up any umbrella, are made so as to protrude from and retract into, the shaft, from the top. [0049] The closing of this umbrella takes place the v opposite of the conventional umbrellas-beach umbrellas.
The umbrella portion consisting of the covering, once inserted from the top into the shaft, is not visible anymore . The shaft therefore becomes the case of the umbrella/beach umbrella, which thus obtains a permanent protection even when not used for a long time. [0050] The open umbrella, subject of the invention described, can take up a horizontal position, relative to the shaft, but it is also capable of taking up positions similar to the conventional umbrellas, that is, inclined downwards or also upwards, according to the construction type .
[0051] Following the actuation of the motor means, for example by a button, the umbrella opens as follows. The threaded staff starts the rotation, causing the rise of the stick translation unit which, at the end of the stroke, makes the wheels adhere to the movement unit for the extension of the sticks. The opening may be actuated as desired, that is, by a remote control or by a button on panel .
[0052] The threaded staff 700 operates the stick movement a.nd translation units. A first step provides to the rise of the translation box which, once the end of stroke position has been reached, for example through a special electrical contact, disconnects the electro-magnetic brake 305 making the nut screw 301 idle and thus releasing the same from the threaded staff 700.. [0053] In such position, sticks 400 reach a substantially horizontal position so that the friction wheels 410 come into contact with the sliding or friction surface 310 of plate 311.
[0054] The other steps keeps plate 311, which belongs to the stick movement unit, in rotation and actuates screw connecting wheels 410, which control the extension and the return of the sticks (figure 5) .
[0055] Screw 700 is connected to nut screw 301, intended for adhering to staff 700 through the electro-magnetic brake 305, which disconnects when the entire stick translation box has risen and has reached the end of stroke relay. The screw is further connected to the sticks, which have been idle so far and which, in the adhesion to the sliding surface 310 that is integral to plate 311, start moving controlled by the inner screw 405. In turn, the screw is controlled by the rotation of wheel 410.
[0056] According to the direction of rotation, therefore, the inner telescopic staff 403 extends or retracts moving sheet 502 therewith, which constantly remains tensioned by the effect of the tensioning springs 501. The sheet tensioning plate 500, on guides, continuously slides along the threaded staff or control screw 700, keeping the distance thereof from the stick ends almost constant. [0057] In the rotational operation thereof, the control screw 700 pulls the sheet tensioning plate 500, with vertical translation movement, thanks to the fact that plate 500 itself cannot rotate on itself as it is guided by the guide bars 800 arranged into shaft 200. Said plate 500 runs through the entire shaft 200 keeping sheet 502, intended for extending for forming the umbrella covering, tensioned through springs 501.
[0058] In a further embodiment, plate 500 is eliminated, sheet 502 is free and the tensioning thereof is ensured by counterweights arranged at the end of the sheet itself . [0059] The stick guiding stop 415 allows maintaining the sticks in equidistant position, also performing the task of giving a counter-thrust to the stick, such as to allow the best adhesion of the screw connecting wheel 410 to the sliding surface 310. [0060] Moreover, the adhesion of the screw connecting wheel 410 is ensured by the thrust spring 313.
[0061] When the umbrella reaches the closing position, the telescopic sticks arrange in vertical position and the movement unit in low position, the whole contained within shaft 200; in other words, the sticks gather upwards and insert into shaft 200. [0062] As can be understood from the description, the umbrella according to the present invention allows overcoming the disadvantages of the umbrellas of the prior art . [0063] The mechanism used for the umbrella can found application for any other type of protection such as rain umbrella, sun protection on boats or else, it may be made with different configurations, provided it can then be automatically reinserted into the shaft, etc. [0064] The invention may for example be used into hotel gardens, in bathing establishments or, in the agricultural field, to protect the plantations by suitably replacing the covering sheet with anti-hail net, etc . [0065] The finding is to be regarded as innovative, as compared to the previous solutions, since the opening and closing operations do not require any efforts by the operator. It is understood that, given the possibility of being actuated by a remote control, it is possible to open and close a desired number of such umbrellas, in a sequence or at the same time, or one at a time, by an opening-closing control panel/device.
[0066] A man skilled in the art may make several changes and adjustments to the umbrellas described above in order to meet specific and incidental needs, all falling within the scope of protection defined in the following claims.
