Definitions
- Base for a device comprising a mast
- the present invention relates to a base comprising a mast base and a ballast.
- It relates generally to the field of pedestals adapted to the stabilization of umbrellas or other devices implementing a fixed mast, of a similar size to the mast of a parasol such as for example a barnum, a flag, or a banner.
- a device comprising a fixed mast, such as an umbrella
- a fixed and stable anchorage This anchoring can in a known manner be obtained by planting the end of the mast in the ground or the surface on which the device is installed.
- a base typically consisting of a concrete block having an insertion hole of the mast.
- umbrella bases typically cast iron or steel, having a tubular mast foot, wherein the mast can be inserted rigidly connected to a monobloc ballast of the mast foot.
- Hollow parasol bases which can be filled with a weighting material such as for example water or sand, are also known in the state of the art, for example in the document EP0822305. Nevertheless, an umbrella base as disclosed in this document is heavy when it is filled, so it is necessary to at least partially empty the ballast material it contains so that a man can wear it.
- a weighting material such as for example water or sand
- the document DE102007012223 presents an umbrella base in which a mast base is weighted by a stack of boxes having an open upper face, the boxes being placed on a cross foot structure.
- the boxes of such a device are difficult to transport individually because of their open character.
- the boxes being placed on a foot structure cross, the center of gravity of the ballast thus formed is slightly raised, which is not optimal for the stability of the base.
- the present invention aims to solve at least one of the aforementioned drawbacks.
- a base comprises a mast foot comprising a plate rigidly connected to a lower end of said mast foot, and at least one ballast traversed by the mast foot through an orifice, in which the ballast has a lower face having a cavity shaped to receive by interlocking the plate, the plate having a shape such that its engagement in the cavity blocks the ballast in rotation relative to the plate.
- the ballast used can be dimensioned according to the device to be stabilized, its size, its windward grip, using a standardized mast foot.
- the interlocking of the plate in the ballast allows a good relative maintenance of these two elements, and can offer a ground support on a large surface, the plate and the ballast can rest on the ground.
- Such a base can, while having a good aesthetic, be easily adjustable, to adapt the ballast to the size of the device to be stabilized by using standardized elements.
- the base can in particular be a flexible umbrella base having the aforementioned advantages.
- the plate and the mast foot can advantageously be monobloc.
- the mast foot with the plate can typically be molded in one piece.
- the plate may have substantially the shape of a disc having a notch, said notching being formed on an upper face of the plate or on the periphery of the plate. This notching makes it possible to obtain a improved maintenance of the plate in the ballast cavity, and blocks platinum and ballast rotating relative to each other.
- the ballast further has a hole on its underside, and a lug positioned on an upper face of the ballast, said lug being of complementary shape to that of the hole.
- the invention also relates to a base comprising a stack of at least two weights, a first ballast being surmounted by a second ballast, and wherein the pin of the first ballast is introduced into the hole of a second ballast.
- the stacking of several weights makes it possible to adapt the mass of the base according to the application in question, while allowing the use of weights of an acceptable unit mass, compatible with the recommendations and legislations, in particular European and American in terms of limitation of the mass of loads during occasional manual handling of unit loads (typically 15 kg maximum for women and 25 kg maximum for men).
- the mast foot may for example be shaped to allow stacking five weights.
- the large weight obtained by stacking the weights allows the application of the invention to large devices having a large wind resistance, and / or devices such as umbrellas with remote feet, having their protective fabric door on their feet.
- Each ballast may be hollow, and may include an opening and means for obstructing said opening, allowing said ballast to be filled with a ballast material.
- the weighting material may be, by way of example, a liquid such as water, or a powdered solid such as sand, or metal balls.
- each ballast has a mass less than or equal to fifteen kilograms, said ballast being filled with water in the case of a hollow ballast.
- ballast filled with dry sand, may have a mass of about 24 kilograms.
- the filling volume of a ballast is advantageously dimensioned so as to be compatible with the recommendations and legislation in terms of limitation of the mass of loads during the occasional manual handling of unit loads.
- the ballast or ballast advantageously have a disc shape, or a flattened shape having an oval, or square, or rectangular, or triangular, or star.
- Each ballast may have a groove on at least a portion of its periphery, arranged to facilitate gripping said ballast.
- Each ballast may have a groove on its underside, said groove connecting the ballast hole to the periphery of the ballast.
- the invention relates to an assembly comprising an umbrella and a base as previously defined.
- FIG. 1 shows a schematic three-dimensional view of a base according to one embodiment of the invention
- FIG. 2 shows in a schematic three-dimensional view of a mast as implemented in the embodiment of Figure 1;
- FIG. 3 shows in a schematic three-dimensional view a ballast as implemented in the embodiment of the invention of Figure 1;
- FIG. 4 shows, in a schematic three-dimensional view, the ballast of Figure 3 with its visible lower face
- Figure 5 shows in the same schematic three-dimensional view that Figure 1, a base according to another embodiment of the invention.
- a base complies with object of the invention can be used, in addition to an umbrella, for the maintenance of many types of devices implementing a mast to be fixed to the ground.
- a pedestal as shown in FIG. 1 comprises a mast foot 1 and a ballast 2.
- the mast foot 1 comprises a tube 1 1 intended to receive a mast, typically a parasol mast or any similar device comprising a mast to be fixed to the ground.
- the mast foot has, in known manner, clamping means 12 for immobilizing the mast in the mast foot 1.
- the clamping means 12 may comprise a screw passing through the tube January 1, orthogonal to the latter. Tightening the screw causes the mast to compress at the end of the screw. The mast is thus rigidly fixed in the mast foot 1.
- the mast foot 1 comprises a plate 13.
- the plate 13 is rigidly connected to a lower end of the mast foot 1.
- the plate 13 is intended to be in surface contact with the ground when the umbrella base is used.
- the plate 13 may have substantially the shape of a disk. Nevertheless, the plate 13 is shaped to be locked in rotation in an element having a cavity of corresponding shape. Platinum 13 does not present a form of pure revolution.
- it has the shape of a disk, comprising, at its periphery or on its upper face, a notch 14.
- the notch 14 comprises, in the example represented here, a set of projections and notches arranged substantially radially, in a star, on the upper surface of the plate 13.
- the notch 14 may, in a variant of the invention not shown, be positioned at the periphery of the plate 13.
- the plate 13 may thus have a shape similar to that of a gear wheel.
- the ballast 2 has a mass 21.
- the mass 21 may be a solid mass object.
- the mass 21 may be steel or cast iron.
- the mass 21 may be concrete.
- the mass 21 can also be obtained by filling an envelope with a ballast material.
- the ballast material is typically a liquid or a sprayed solid.
- the mass 21 may thus comprise a plastic material envelope.
- the envelope of the mass may be filled for example with water, sand, gravel, or metal balls.
- the ballast may comprise an opening 22 and means for obstructing said opening 22, allowing said ballast to be filled with a liquid or a pulverized solid.
- the ballast 2 is traversed by the mast foot 1, through an orifice 23 of the ballast 2.
- the orifice 23 advantageously comprises a groove 24 allowing the passage of elements of the clamping means 12, during the insertion of the mast foot 1 through the ballast 2.
- the ballast is provided on its lower face with a cavity 25 of shape complementary to the shape of the plate 13.
- the plate 13 can be nested in the cavity 25
- the ballast 2 is thus fitted and secured under its weight to the plate 13.
- the orifice 23 generally opens into the cavity 25.
- a total engagement of the plate allows the plate 13 and the ballast 2 to both be in surface contact with the ground during use, which ensures a good stability of the support.
- the ballast is locked in rotation by the complementary shape between the cavity 25 and the plate 13.
- the cavity 25 may have teeth complementary to the notching 14 of the plate 13.
- the ballast 2 further comprises a hole 26.
- the hole 26 is positioned on the lower face of the ballast 2.
- a lug 27 is formed on the upper face of the ballast 2.
- the pin 27 is formed opposite the hole 26. It is thus possible to superpose two (or more) weights 2 ', 2 "for modulate the mass of the base When two ballasts 2 ', 2 "are superimposed, which constitutes a stack at least two weights 2 ', 2 ", a first ballast 2' is surmounted by a second ballast 2".
- the lug 27 of the first ballast 2 ' is introduced into the hole 26 of the second ballast 2 "This ensures a certain mechanical cohesion between the first ballast 2' and the ballast 2", preventing them from turning relative to each other. the other, and allows a good positioning of a ballast relative to the other.
- the good positioning in the relative position of the two weights 2 ', 2 " is particularly important according to aesthetic considerations when each ballast has a shape other than a disc, which is particularly the case when the weights have an oval, square, rectangular contour, triangular, or star.
- the mast foot 1 can typically be sized to allow the stacking of five weights.
- each ballast has a mass less than or equal to 25kg, and preferably less than or equal to 15kg.
- This mass refers to a full ballast, or to a hollow ballast filled with water, or to a hollow ballast filled with sand.
- Such a mass corresponds to the recommendations in terms of limitation of the mass of the loads during the occasional manual handling of unit loads, namely 15 kg at the maximum for the women and 25 kg at the maximum for the men.
- a hollow ballast, whose filling volume is sized to have a mass of 15kg filled with water, may have a mass of about 24kg when filled with dry sand.
- the ballast further comprises a groove 29 on its underside.
- This groove allows the passage of an electric cable, for example for the power supply of a lighting.
- the groove 29 is dimensioned accordingly. It connects the orifice 23, through which the ballast 2 is crossed by the mast foot 1 at the periphery of the ballast.
- the groove 29 advantageously opens into the orifice 23 at the groove 26. It is thus possible to route an electric cable in the groove 29, between a ballast and the ground or between two superimposed weights, then in the groove 26, and finally along the mast foot 1 and a mast of a device fixed in the mast foot 1.
- the invention thus developed makes it possible to modulate an umbrella base around the same mast base, by using a ballast mass and adequate dimensions, or a stack of weights of adequate dimensions, forming a suitable mass. It allows a good cohesion between the foot of the mast and the ballast, or the weights in the case of a stack. It allows easy stacking of ballast of moderate mass, with a good relative positioning of ballast.
