Definitions

  • the present invention relates to a device for anchoring a beach parasol pole in the sand or in a sandy soil.
  • a parasol foot for screwing which consists of a cone surmounted by a tubular part equipped with a screwing grip and a screw for clamping the tube constituting the foot of the parasol.
  • a helical thread is formed around the cone.
  • the parasol foot is screwed into the sand and the parasol pole is inserted in the tubular part, and the pole is locked by tightening the screw.
  • the resistance of the parasol pole to pulling away is improved, because of the increased surface of the parasol foot to be screwed in contact with the sand and the presence of the helical thread, but does however remain insufficient to retain it in a blast of wind.
  • a portable support base for holding a parasol in the sand is also known.
  • the support base comprises a membrane and a mounting support.
  • the membrane is in the form of a disc, and is manufactured from a fabric woven in a PVC-coated polyester fibre.
  • the thickness of the membrane is 0.75 mm.
  • the diameter of the disc is between 46 cm and 91 cm and ideally measures 60 cm.
  • the mounting support comprises an upper part situated on the top side of the membrane and a lower part situated on the bottom side of the membrane.
  • the two parts are attached to each other or to the membrane.
  • the mounting support is defined by a central tubular element through which there passes an internal bore a little larger than the diameter of the rod of the parasol and is surrounded by an upper outer sleeve.
  • the latter is secured in the membrane by force fitting, by a fixing or with an adhesive. It is manufactured from rubber or plastics material, such as PVC.
  • the upper outer sleeve has a thread passing through it wherein a clamping screw makes it possible to lock the rod of the parasol.
  • a device for anchoring a pole for a beach parasol in the sand or in a sandy soil, comprising a buriable plate manufactured from a flexible or semi-rigid material, a sleeve intended to receive said pole, the sleeve being associated with said plate by means of a junction zone, the sleeve opening out on both sides;
  • the sleeve comprises a tubular inner wall connected to the outer wall by means of radial ribs, said radial ribs being extended towards the inside of the tubular inner wall so as to come into contact with the wall constituting the pole.
  • the sleeve does not require any additional clamping device for holding the parasol pole.
  • the anchoring device is relatively economical to manufacture.
  • a tubular intermediate wall is formed between the outer wall and the tubular inner wall, the tubular intermediate wall being connected to the outer wall and to the tubular inner wall, by means of radial ribs.
  • the sleeve has in front view an outer wall in the form of a truncated cone and the large base of which forms the junction with the buriable plate.
  • This form of the sleeve procures for it good mechanical strength and increases the pressure that the sand exerts around the sleeve when the anchoring device is buried.
  • openings pass through the buriable plate at the junction zone and radial folds delimit, in the buriable plate, facets in the form of angular sectors, from the sleeve as far as the periphery of the buriable plate, at least one radial fold being secant to an opening.
  • the openings provide flexibility in the junction zone.
  • the facets are thus less deformed by the inclination of the sleeve in a situation of wind on the parasol. They can thus remain stable when they are kept captive in the sand, which avoids loosening of the buriable wall.
  • the openings allow folding of the facets in line with the sleeve.
  • alveoli are formed on the top face, intended to be turned upwards, of the buriable plate.
  • Studs are formed in the burying sand, which increases the resistance of the device to pulling away and improves safety thereof in operation.
  • the bottom face of the buriable plate has a smooth appearance.
  • the smooth bottom face procures a sucker effect for the buriable plate with an underlying damp sand.
  • the buriable plate has, when it rests on a flat support, the form of a disc with a diameter of between 20 cm and 40 cm+/ ⁇ 2 cm with a preferential value of 30 cm+/ ⁇ 2 cm.
  • the anchoring device is effective for the majority of beach parasols where the diameter of the open fabric is approximately 180 cm.
  • the anchoring device includes a pole for a parasol.
  • This assembly makes it possible to accommodate a parasol mast.
  • the anchoring device includes a parasol mast equipped with a fabric and a mechanism for deploying same.
  • This assembly procures self-contained use of the parasol.
  • a method for manufacturing an anchoring device forms part of the invention.
  • the anchoring device is manufactured by moulding, the buriable plate and said sleeve forming one and the same object manufactured in a single piece.
  • the anchoring device manufactured by moulding is ready to be used. It is packaged so as to be offered for sale.
  • the material chosen is an elastomer, the hardness of which is between 60 and 90 ⁇ 8 IRHD, the thickness of the buriable plate being between 2 and 10 mm with a preferential value of 3 mm.
  • FIG. 1 shows a perspective view of a device for anchoring in the sand a beach parasol pole according to the invention
  • FIG. 2 shows a front view in cross section of a device for anchoring a beach parasol pole in the sand, wherein the buriable plate that constitutes it is set flat on a surface while forming a disc according to the invention
  • FIG. 3 shows a plan view of a device for anchoring a beach parasol pole, wherein the buriable plate that constitutes it is open, forming a disc according to the invention
  • FIG. 4 shows a view in cross section of a sandy soil wherein a device for anchoring a beach parasol pole according to the invention is buried
  • FIG. 5 shows a view in cross section of a sandy soil wherein a device for anchoring a beach parasol pole is buried, the actions of the effect of the wind on the parasol being simulated on the pole according to the invention.
  • the anchoring device 100 presented in FIGS. 1, 2 and 3 , is intended to anchor, in a secure manner, the pole P forming a parasol, in the sand of a beach or in a sandy soil.
  • It is composed of a buriable plate Pf, and a sleeve Mn for receiving a pole P for a parasol.
  • the buriable plate Pf is set flat on a support surface N to simulate a burying situation.
  • the buriable plate Pf in this situation preferably is in the form of a disc D so that the user of the anchoring device 10 does not have to choose its best operating orientation.
  • the diameter of the disc D is between 20 cm and 40 cm+/ ⁇ 2 cm depending on the size of the beach parasol, with a preferential value practically equal to 30 cm+/ ⁇ 2 cm, corresponding to the majority of beach parasols, the diameter of the open fabric of which is approximately 180 cm.
  • planar buriable plate Pf is manufactured from a flexible or preferentially semi-rigid material, manually deformable, but which does not suffer permanent deformation, in the range of normal use.
  • the hardness of the elastomer is selected between 60 and 90 ⁇ 8 IRHD.
  • the elastomer is selected in particular from nitrile, EPDM (the abbreviation for ethylene propylene diene monomer), silicone or rubber.
  • the elastomer selected is preferably a regenerated polypropylene.
  • a material that is well suited for manufacturing this plate Pf is a flat sheet of elastomer with a thickness of between 2 mm and 10 mm. A value of 3 mm procures correct strength and sufficient rigidity.
  • the top face of the buriable plate Pf that is intended to be turned upwards has alveoli V for being able to receive by moulding a plurality of aggregates of sand grains and thus to increase the surface of contact of said plate with the mass of sand situated above it.
  • the bottom face of which is smooth to procure a sucker effect with an underlying damp sand.
  • the alveoli V are aligned radially. They have a square shape at the periphery of the burying plate that changes towards a rectangular shape when approaching the sleeve Mn, and delimiting between them relatively small separations of almost constant thickness. A thousand alveoli at a minimum are formed in the buriable plate Pf. In this way, a plurality of studs are formed by moulding in the burying sand, which increases the resistance of the device to pulling away and improves the operating safety thereof.
  • the material forming the buriable plate Pf may incorporate a reinforcement frame T made for example from a plurality of crossed polyester fibres, to increase the resistance to tearing of the buriable plate Pf.
  • the sleeve Mn is connected to the buriable plate Pf by means of a zone of a junction Zj.
  • the sleeve Mn is erected perpendicular to the top face of the disc D and at the centre thereof. It is intended to receive the part of a beach parasol pole P that is normally intended to be buried in the ground.
  • the anchoring device 100 of the invention is manufactured in a plastic-injection mould.
  • the sleeve Mn thus forms an integral part of the anchoring device 100 , i.e. the buriable plate Pf and said sleeve Mn form one and the same object manufactured in a single piece.
  • This embodiment is suitable for mass production.
  • the sleeve Mn opens up on both sides. It has in front view an outer wall Tc in the form of a truncated cone Tc, the large base of which forms the junction Zj with the buriable plate Pf in order to procure for it good mechanical strength and to increase the pressure of the sand around the sleeve Mn.
  • the sleeve Mn is defined by a tubular inner wall Pt wherein it is necessary to insert the pole of the parasol.
  • the tubular inner wall Pt preferentially has a cylindrical shape, as is clear in this FIG. 2 .
  • this tubular inner wall Pt is connected to the outer wall Tc by means of a plurality of radial ribs Nv for accepting the deformation of said tubular inner wall.
  • tubular inner wall Pt can increase in size during the insertion of the pole in order to accept poles with various diameters.
  • a tubular intermediate wall Pti is formed between the outer wall Tc and the tubular inner wall Pt.
  • This tubular intermediate wall Pti is connected to the outer wall Tc and to the tubular inner wall Pt, by means of the radial ribs Nv.
  • the tubular intermediate wall Pti preferentially has a cylindrical shape, as is clear in this FIG. 2 . The presence of this tubular intermediate wall Pti increases the stiffness of the tubular inner wall Pt.
  • the radial ribs Nv are extended inside the tubular inner wall Pt and are sized so as to come into contact with the wall of the pole P.
  • These projecting parts of the ribs Nv inside the tubular interior wall Pt firstly facilitate the insertion of the pole by rotation in said tubular inner wall Pt while flexing the projecting parts of said ribs, and secondly increase the clamping of the pole in the sleeve Mn by the relatively high pressure that they exert on the wall of the pole T.
  • the user can turn the pole P in the opposite direction in the tubular internal wall Pt to return the projecting parts of the ribs Nv into a radial plane.
  • openings Ov pass through the buriable plate Pf at the junction zone Zj.
  • Four openings Ov are distributed regularly around the axis of the tubular intermediate wall Pt.
  • radial folds Jr delimit in the buriable plate Pf facets in the form of angular sectors Sa, from the sleeve Mn as far as the periphery of the buriable plate Pf. At least one radial fold Jr is secant to an opening Ov.
  • the facets Sa have a semi-rigid structure because of the nature of the material constituting the device 100 and because of the thickness of said facets.
  • Each radial fold Jr is formed by a groove of constant width hollowed out in the thickness of the buriable wall Pf, from the upper face thereof.
  • the facets Sa thus articulated can then move in order to match the approximately flat relief of the sand on which said buriable wall is resting.
  • the facets Sa can fold around the sleeve Mn and in line with it in order to form practically an easily transportable cylinder.
  • the anchoring device 100 can be supplied with a link, such as an elastic strap, for keeping said facets folded.
  • the alveoli V are formed solely in the facets Sa.
  • the alveoli are present over at least half of the surface of the facets Sa.
  • the operation of the anchoring device 100 is as follows with reference to FIGS. 4 and 5 : the end of a beach parasol pole P is fitted into the tubular interior wall Pt of the sleeve Mn. The projecting parts of the radial ribs Nv then come into contact with the wall of the pole P to hold it firmly in the sleeve Mn.
  • the pole P can be turned in one direction in the sleeve Mn to curve the projecting parts of the radial ribs Nv.
  • the end of the pole is fitted in so that the tapered end thereof emerges from the sleeve Mn by at least around ten centimetres.
  • the adhesion of the projecting parts of the radial ribs Nv on the tube constituting the pole T suffices to hold it since the pressure applied is relatively high.
  • the tubular inner wall Pt and the tubular intermediate wall Pti can expand while longitudinally compressing the ribs Nv to accept a larger pole.
  • the thicknesses of the tubular inner wall Pt, of the tubular intermediate wall Pti and of the ribs Nv, and the spacing between the tubular inner wall Pt and the tubular intermediate wall Pti, and between this tubular intermediate wall Pti and the outer wall Tc are calculated so that the sleeve Mn can accommodate and hold a pole T the diameter of which is between 22 and 25 mm.
  • the anchoring device 100 equipped with a pole P, is then ready to be used.
  • the sand at the location where the parasol is to be placed is hollowed out to a depth of around twenty centimetres.
  • the buriable wall Pf is opened and deposited substantially flat on the uncovered surface of the sand, the facets Sa matching the imperfect flatness of the sand, and the buriable wall Pf is then buried by covering it with the sand B previously removed.
  • the facets Sa of the disc D rest through their bottom faces on the sand and the top face of the buriable wall Pf is covered with a mass of sand B that builds up by moulding in the alveoli V to increase the capacity for retention of the sleeve in said mass of sand.
  • the mast of the parasol is next mounted on the pole P anchored in the sand B. The pole P is thus held in the sleeve Mn secured to the buriable wall Pf, which extends practically in a horizontal direction and is held captive in a mass of sand.
  • the relatively rigid form of the facets Sa remains stable in the sand B by virtue of this flexible junction zone Zj.
  • the form of the buriable plate Pf consequently also remains stable under the force of the inclination of the sleeve Mn through the effect of the wind on the parasol.
  • the lateral movement of the buriable plate Pf is practically non-existent because of the relatively large surface of the two faces thereof, top and bottom, in contact with the sand B.
  • the alveoli V present on the top face of the buriable plate Pf and the smooth bottom face in contact with moist sand reinforce this tendency of the disc not to slide laterally.
  • the mass of sand B located above the buriable plate Pf traps it.
  • the buriable plate Pf is as if held in a vice.
  • sand penetrates the interstices present inside the sleeve Mn.
  • sand can thus penetrate between the pole P and the tubular inner wall Pt, between this tubular inner wall Pt and the tubular intermediate wall Pti, and between this tubular intermediate wall Pti and the outer wall Tc.
  • the sand built up in the sleeve Mn blocks the expansion of the tubular inner wall Pt and of the tubular intermediate wall Pti so that the clamping of the projecting parts of the ribs Nv on the wall of the pole P is maintained, in particular when the sleeve slopes under the effect of the wind on the parasol.
  • the relatively high pressure exerted by the projecting parts of the ribs Nv on the tubular wall of the pole P associated with the presence of sand in the sleeve Mn helps to hold said pole firmly in the sleeve Mn and thus prevents pulling away thereof.
  • a device for anchoring a pole for a beach parasol in the sand as well as such a pole also form part of the invention.
  • a device for anchoring a pole for a beach parasol in the sand as well as such a pole and the parasol mast thereof equipped with fabric and a mechanism for deploying same also form part of the invention.
  • the buriable plate can be redeployed around the pole to facilitate transport thereof.
