Definitions

  • the present invention relates to a parasol and more precisely its deployment and deployment device.
  • the object of the invention is to remedy the drawbacks aforementioned using simple and reliable means. It facilitates the handling of parasols of the offset mast type by limiting the effort to provided by the user.
  • the parasol of the invention is of type comprising a main mast and a secondary radial arm movable in displacement relative to the main mast between an inactive position folded and an active position deployed, and is characterized in that it includes a deployment and / or deployment aid intended to exert a force so as to cause the arm to move secondary to its folded and / or deployed position.
  • the arm radial is slidably mounted in a pivotally pivoted clevis the end of the main mast and is actuated in displacement by the pivoting of an articulation and control arm articulated on the mast main at one of its ends and on the secondary arm at the other of its extremities.
  • the deployment and / or deployment assistance device includes additional deployment means arranged between the main mast and the articulation and control arm intended to stress moving the control arm and the secondary arm towards their deployed position.
  • the means of additional deployment are constituted by a jack articulated on the main mast at one end and articulated on the control arm at the other end.
  • the jack is arranged between the main mast and the control arm, so as to be in maximum compression position when the parasol is in position folded up.
  • the cylinder is arranged between the main mast and the control arm so that it is in the maximum compression position when the parasol is in an intermediate position located between the folded position and the deployed position.
  • the jack forces the control arm and the secondary arm towards their position deployed, while on the other side of the intermediate position, the jack requests the arms towards their folded position.
  • its intermediate position is located in the vicinity of its folded inactive position.
  • a yoke carrying a radial arm articulated secondary while a control and link arm is hinged between the top of the mast and the secondary arm to allow the secondary arm to move from a folded position to a position deployed.
  • the deployment assistance device and / or when folded back is placed between the control and link arm (15) and the secondary arm (14).
  • Figures 1 to 9c illustrate several embodiments of the parasol and its deployment and / or folding aid.
  • Figure 1 illustrates in perspective a parasol with offset pole folded position.
  • Figure 2 shows, in a view similar to Figure 1, the parasol in the deployed position.
  • Figures 3a to 3d illustrate in side view a first mode of realization of the parasol respectively in the folded position in two passage positions and in the deployed position during its deployment.
  • Figures 4a to 4d illustrate in side view a second mode of realization of the parasol respectively in folded position, in position intermediate, in a passage position, then in the deployed position.
  • Figure 5 illustrates in perspective the cylinder and its joints.
  • Figures 6a, 6b and 6c illustrate respectively in side view a first position close to the intermediate position, the position cylinder compression intermediate, and a second neighboring position from the intermediate position on the other side.
  • Figure 7 illustrates in side view a third mode of realization of the parasol of the invention in the folded position.
  • Figure 8 illustrates in a view similar to Figure 7 the parasol in the deployed position.
  • Figures 9a to 9c illustrate in three successive positions a variant of the third embodiment of the parasol
  • the parasol bearing the general reference (1), is of the offset mast type. It has a secondary radial arm (3) arranged movable in displacement relative to a main mast (2) between a folded inactive position (A) and deployed active position (B). Note that this secondary arm could be mounted mobile, no longer on a mast main, but equivalently on a form frame any fixed in the ground or likely to be moved.
  • the parasol (1) comprises a device for assisting the deployment and / or folding (DA) of the secondary arm (3).
  • This device is intended to assist movement of the radial secondary arm (3) from its inactive position (A) to its active position (B) or vice versa.
  • the deployment or deployment aid (DA) includes additional deployment means and / or means of additional deployment, this or these means being susceptible to exert a force on the secondary radial arm (3) so as to train it on the move to bring it to its deployed position (B) and / or towards its folded position (A).
  • this is in the form of a main mast (2) at the end which is pivotally mounted a yoke (4) in which the secondary arm (3) can slide.
  • the secondary radial arm carries to one of its ends the set of whales (35) on which the canvas (5) as well as its opening and closing means (MOF) and is articulated at the other of its ends on a control articulation arm (6) pivotally mounted on the main mast (2) around a pivot axis (7). It can be noted as shown in Figures 1 and 2 that in this mode of realization the fabric (5) passes over the secondary arm (3)
  • the arm articulation and control (6) pushes the radial arm (3) to slide in the yoke (4) which pivots on the main mast (2).
  • This sliding and this pivoting which takes place at the level of the yoke (4) allow the arm secondary (3) to pass from its folded position (A) where it is vertical towards its active deployed position (B) where it is cantilevered on the main mast (2) in order to leave the space under the canvas (5).
  • the combined movement of the articulation and control arm (6) and the secondary radial arm (3) towards their deployed position (B) is obtained with the help of means of additional deployments that allow the implementation of a force (F) intended to drive said arms (3, 6) in movement.
  • Ways of additional deployment are advantageously arranged between the main mast (2) and the control arm (6) so as to exercise their force (F) on the articulation arm (6) to cause it to pivot in less during part of its movement between its folded position (A) and its deployed position (B). It goes without saying that these means could be arranged directly on the secondary radial arm without going out of the protective field of the invention.
  • the deployment means complementary are constituted by a jack (8) such as, for example, a pneumatic, gas, hydraulic or other cylinders mounted articulated in pivoting on the main mast (2) at one of its ends (8a) and on the articulation and control arm (6) at the other of its ends (8b).
  • a jack (8) such as, for example, a pneumatic, gas, hydraulic or other cylinders mounted articulated in pivoting on the main mast (2) at one of its ends (8a) and on the articulation and control arm (6) at the other of its ends (8b).
  • the parasol only comprises additional deployment means that stress the arm articulation from its folded position (A) to its extended position (B) in it imparting a force (F), and this, during its entire pivoting.
  • the force (F) of the jack (8) impressed on the articulation arm (6) is arm position and decreases during movement of the arms (3, 6) from their folded position to their deployed position.
  • the jack (8) is arranged so as to be in the maximum compression position when the arms (3, 6) are in folded position (A).
  • the parasol comprises folding means which allow the loading of the arm articulation and the secondary arm from their deployed position towards their folded position.
  • These means can advantageously be constituted by elastic return devices which tend to return the arm hinge to its folded position. Note that for this mode of realization, in the deployed position (B), the weight located on one side of the yoke (canvas, opening means and secondary arm) creates a couple which opposes the force of the folding means and which is greater than said restoring force to obtain a stable deployed position (B).
  • the parasol (1) comprises deployment assistance resources and deployment assistance resources.
  • deployment assistance resources can advantageously be formed by the same organ such as, for example, a jack (8) capable of requesting pivoting from the articulated arm (6) to one or other of its extreme positions in function of the position in which the parasol (1) is located.
  • the parasol (1) is of the type with offset mast and has a secondary radial arm (3) and arm system control (6) similar to that described in the first mode of production.
  • the jack (8) is arranged so that when the secondary arm (3) and the arm are moved control (6), the distance (L) between the hinge pins (8a, 8b) arranged at its ends passes through a minimum (L1) corresponding to a intermediate position (C) where the cylinder (8) is in the compression position maximum.
  • the intermediate position (C) of the arms (3, 6) and the cylinder (8) is an unstable equilibrium position. So when the tilting system on one side of the intermediate position (C), the cylinder (8) constitutes an additional means of deployment by stressing the arms (3, 6) towards their deployed position (A), while, on the other side of the intermediate position, the jack (8) biases the arms (3, 6) towards their folded back position (B) and therefore constitutes a means of assisting the folding back.
  • the jack (8) and more precisely its articulations (8a, 8b) are positioned so that the intermediate position (C) of unstable equilibrium of the device is located in the vicinity of the folded inactive position.
  • the pivot angle ( ⁇ ) not shown necessary for the articulation arm (6) to pass from its folded position (B) towards its intermediate position (C) is between 0 and 30 ° and advantageously chosen substantially equal to 10 °.
  • the intermediate position (C) could be positioned differently by relative to the deployed (A) and folded (B) positions and to be located in a middle position between the two extreme positions.
  • the jack (8) is advantageously a pneumatic type jack.
  • the means to deployment or re-deployment could be obtained by bodies equivalents such as compression springs or the like.
  • the transfer of weight which takes place when the secondary arm (3) slides in the clevis (4) carried by the main mast makes it possible to create a couple around the pivot point of the yoke which also trains the arms articulated (3, 6) towards their extreme positions.
  • This weight transfer as well that the particular kinematics of the two arms (3, 6) require a precise positioning of the jack (8) as well as a dimensioning thereof to allow obtaining the desired characteristics and especially to relieve the torque created by the weight so as to make easy deployment and folding of the parasol by the user to avoid it from making too much effort when opening and closing the parasol.
  • a third embodiment of the parasol (1) of the invention is formed by a main mast (12) on which is sliding mount a yoke (13) carrying a secondary radial arm (14) Speak clearly.
  • a control and connection arm (15) is articulated between the top of mast (12) and secondary arm (14) to allow the arm secondary to pass from a folded position (A) illustrated in Figure 7 where it found substantially vertical towards a deployed position (B) illustrated in figure 8 in which it is cantilevered at the end of the main mast (12).
  • the movement of the articulated arms (14, 15) is due to the translational movement of the yoke (13) which is obtained at using a chain system (17) known per se, actuated for example by a handle (20).
  • the parasol (1) comprises a jack (18) intended to exert a force (F) directly or indirectly on the chain (17) or on the yoke (13) to slide it from its low position (A) corresponding to the folded position of the parasol towards its high position (B) corresponding to the deployed position.
  • the jack (18) can be mounted between a stop (19) located on the mast main (12) and the sliding handle (20) fixed to the chain so as to bias the yoke (13) from its low position (A) to its high position (B) through the chain (17).
  • This cylinder (18) therefore constitutes the additional deployment means for the parasol (1).
  • the opening and closing of the whales (35) carrying the fabric (5) is obtained using a control cable (40) fixed to a traction point (45) located on the chain (17), said point undergoing a reverse movement to that of the sliding yoke (13) so as to cause the displacement of the nut (50) of the opening and closing (MOF). It goes without saying that one could foresee on this mode of realization of the re-folding means or mixed means allowing deployment or deployment without departing from the scope of protection of the invention.
  • the jack (8) is arranged between the secondary arm (14) and the control and link arm (15) to allow the stressing of the secondary arm to its deployed position. It is important to note that according to this variant, the jack can be arranged so as to have a maximum compression position corresponding to a intermediate position of the parasol close to the folded position of the arm secondary as in the second embodiment of the parasol so as to obtain in particular a stable folded position.
  • the fabric (5) does not cover the secondary arm (14) but is held below said arm by a set of whales (35) arranged under the secondary arm.
