Description

Title of the invention: Raised floor support

[0001] The present invention relates to a pedestal, for a raised floor and a raised floor comprising such a pedestal.

[0002] A raised deck for a terrace is known, comprising pedestals supporting rows of parallel longitudinal joists spaced approximately fifty centimeters apart, and transverse braces maintaining the spacing between the joists of two successive rows. Wooden or composite material planks forming a floor surface are laid and fixed onto the joists. Each pedestal has a head whose height is adjustable to be coplanar with the heads of the other pedestals, ensuring the flatness of the floor surface.

[0003] For sections bordering the raised floor where the floor surface is not bordered by a wall and is raised above ground level, a facade surface is provided to close off the space beneath the floor surface. This facade surface can be made, for example, of the same wood planks as the floor surface. The facade surface is generally supported by vertical posts, usually made of wood or the same material as the joists, distributed along the edge of the raised floor. For sections of the edge where the ends of the joists terminate, each lateral post must be fixed to one of these joist ends, extending between the floor surface and the joist, at a distance from the ground to prevent moisture from rising from the floor surface via the lateral post.Depending on the situation, the post can alternatively be mounted against the end of the joist rather than under the end of the joist, but always at a distance from the ground surface. For sections of the edging running alongside an end joist, each side post must be fixed to the end joist, extending between the ground surface and the end joist, at a distance from the ground to prevent rising damp, and while supporting the end joist.

[0004] To support the facade surface and prevent any risk of deformation, given the materials (wood or wood composite), a maximum center-to-center distance must be observed between two successive lateral posts. For example, a lateral post is planned every 50 cm. This also implies that a substantial number of lateral posts are necessary to support the facade surface, generally one lateral post per block. In addition to the fact that many lateral posts are required, their installation is generally difficult, particularly regarding their positioning. Indeed, the lateral post is installed after the blocks are already in place, but the floor surface is not yet in place. The lower end of the side post is generally placed on a support surface belonging to the pedestal, which keeps the post away from the ground. However, several measurement steps are necessary to perfectly position each side post, ensuring the flatness and correct positioning of the future facade surface, which will later be attached to the posts. The positioning of the upper end of the side post, which is attached to the joist, depends on the correct positioning of the joist and on the joist having been precisely cut to the correct length during installation. Side posts positioned in this way, if not yet attached at their upper end or if any bonding of their lower end to the pedestal is of poor quality, are at risk of being accidentally displaced.

[0005] The aim of the invention is then to propose a new support for a raised floor, guaranteeing the correct positioning of a lateral support and simplifying the installation of the raised floor.

[0006] To this end, the invention relates to a support / pedestal for a raised floor, the support comprising: • a base, crossed by a base axis and configured to rest on a ground surface so that the base axis is perpendicular to the ground surface; • a lower cradle, fixedly attached to the base, configured to receive as support a lower end of a lateral upright of the raised floor in order to keep the lower end away from the ground surface; • a head, configured to support a floor surface of the raised floor; • a connection, through which the base supports the head so that the head is traversed by the base axis and the position of the head relative to the base is adjustable; and • an adapter, integral with the link or the head, and comprising an upper cradle, configured to receive as support an upper end of the side post, such that an axis of the post passing through the lower end and the upper end thus received is parallel to the axis of the base,

[0007] in which the upper cradle comprises: • an upper external radial bearing surface, for internal radial support of the upper end of the side post against said upper external radial bearing surface; and • a tab, which projects radially outwards from an orthoradial end of the upper external radial bearing surface, for a setting in orthoradial support of the upper end of the lateral upright against the tab.

[0008] A key idea of ​​the invention is to provide the pedestal with means for positioning both the lower and upper ends of the lateral support, namely the lower and upper cradles. This allows the lateral support to be reliably positioned without requiring measurements, since the geometry of the pedestal, and in particular of the cradles, is predetermined during its manufacture, unlike the dimensions of other elements of the raised floor, such as joists, which are generally cut / adjusted in situ during installation. Specifically, the upper end of the pedestal is positioned not only in a radial direction, bearing against the upper external radial support face, but also in an orthoradial direction, that is, parallel to the facade surface, bearing against the miter.Thanks to the tab, the spacing of the studs advantageously determines the spacing of the side posts, if several studs are planned and each of them receives a respective side post.

[0009] Furthermore, to prevent the risk of accidentally altering the position of the side post before its final attachment to the joist, providing a lower cradle and a lower support cradle advantageously allows for two-point attachment, either temporary or permanent, namely, for example, by gluing the lower end to the lower cradle and by gluing or screwing the upper end to the upper cradle. This does not preclude subsequently permanently attaching the side post, preferably to the joist supported by the pedestal or adjacent to the pedestal, for example, using a screw.

[0010] According to other advantageous aspects of the invention, the invention comprises one or more of the following features, taken individually or in all technically possible combinations:

[0011] - The lower cradle comprises a lower external radial support face, for a internal radial support of the lower end of the lateral upright against said lower external radial support face.

[0012] - The lower cradle includes a support face, to support the end lower, keeping the lower end away from the ground surface when the base rests on the ground surface.

[0013] - The adapter can assume several distinct orientations relative to the base around the base axis.

[0014] - The adapter can be detached from the link or, respectively, from the head.

[0015] - The connection comprises a base element, supported by the base, and a base element head, supporting the head, as well as a screw and nut coaxial with the base axis and engaged by screwing one into the other so that the position of the head relative to the base either adjustable along the base axis, the screw belonging to a first element among the head element and the base element, the nut belonging to a second element, distinct from the first element, among the head element and the base element.

[0016] - The adapter is integral with the head element.

[0017] - The head element includes a retaining part centered on the base axis.

[0018] - The adapter includes at least one hook which surrounds the retaining part, around of the base axis, so that the adapter is fixed to the connection, the head element includes a retaining part centered on the base axis.

[0019] - The head element includes an actuating ring, via in which the head is configured to be rotated relative to the base element around the base axis.

[0020] - The head includes a plate, through which the head is configured to support the floor surface and which is transverse to the base axis.

[0021] - Said at least one hook is received axially between the crown and the plate when the adapter is attached to the connection.

[0022] The invention also relates to the raised floor, comprising: the pedestal, as defined above; the floor surface, supported by the head; the lateral post, the lower end being received in support against the lower cradle and the upper end being received in support against the upper cradle, being fixed to the pedestal by means of the upper cradle; and a facade surface supported by the lateral post.

[0023] The invention will become clearer upon reading the following description, given solely by way of non-limiting example, and made with reference to the drawings in which:

[0030] Fig. 1 shows part of a raised floor 1, constituting, for example, an outdoor terrace, comprising joists 10, of which only one is shown, a side post 20, of which only one is shown, a facade surface 35, a surface of floor 30, pedestals 40, of which only one is shown, the pedestals 40 resting on a floor surface 2. [Fig.6] shows another part of the raised floor, from another angle, with two other joists 10, another lateral post 20, another pedestal 40, another facade surface 38 and another part of the same floor surface 30.

[0031] The joists 10 are parallel to a horizontal longitudinal direction X. The facade surface 35 is perpendicular to the X direction. The floor surface 30 is perpendicular to a vertical direction Z, directed upwards, perpendicular to the X direction. The floor surface 30 consists of boards 31 that are parallel to a Y direction, perpendicular to the X and Z directions, and horizontal. The facade surface 35 consists of boards 36 that are parallel to the Y direction. The facade surface 35 is perpendicular to the Y direction. The facade surface 38 consists of boards 39 that are parallel to the X direction.

[0032] The joists 10, studs 20, boards 31, boards 36, and boards 39 are preferably made of wood, or of a composite material containing essentially wood, or of a wood-based composite material. The boards 31, 36, and 39, which are visible, may be made of a different material than the joists 10 and studs 20, which are concealed beneath the floor surface 30 and behind the facade surface 35.

[0033] The blades 31 are preferably distributed in rows of blades 31 along the X direction. The blades 36 are preferably distributed in rows of a few blades 36 along the Z direction. The blades 39 are preferably distributed in rows of a few blades 36 along the Z direction.

[0034] Preferably, the joists 10 and the uprights 20 are made of the same profiled material, with a rectangular cross-section. The joists 10 and the uprights 20 therefore advantageously have the same cross-section.

[0035] The joists 10 are distributed along the Y direction. Along the X direction, several joists 10 can follow one another in alignment with each other, in the case where a single joist 10 would not be long enough to cover the entire length of the raised floor 1 along the X direction.

[0036] Preferably, some of the joists 10, such as that of [Fig. 1], are arranged in a "simple joist arrangement", that is to say, they are spaced from each other along the Y direction by a center-to-center distance, measured along the Y direction, which is large, for example between 40 and 70 cm (centimeters), preferably 50 cm. At least one strut is interposed along the Y direction between two adjacent joists 10 along the Y direction when they are in a simple joist arrangement. Preferably, several struts are even provided interposed along the Y direction and spaced along the X direction between said joists 10, ensuring compliance with the desired center distance and the parallelism of said joists 10. The braces all have the same length along the Y direction.

[0037] Preferably, other joists 10, like those in [Fig. 6], are arranged in a "double joist arrangement", that is to say, they are spaced from each other along the Y direction by a center-to-center distance, measured along the Y direction, which is smaller, for example between 40 and 60 mm (millimeters), preferably 50 mm. Advantageously, it is provided that there is no cross brace interposed between the adjacent joists 10 in a double joist arrangement.

[0038] The floor surface 30 rests on the joists 10 and is fixed to them, for example by means of screws. The joists 10 are distributed over the entire area of ​​the raised floor 1, in order to support the floor surface 30 in the direction Z.

[0039] Preferably, the floor surface 30 is delimited by a transverse edge 32, parallel to the Y direction, shown in [Fig. 1]. The transverse edge 32 is preferably formed by the last boards 31 of the floor surface 30 in the X direction. As shown in [Fig. 1], the joists 10 extend almost to the transverse edge 32, to support the boards 31 constituting the transverse edge 32.

[0040] Preferably, the floor surface 30 is also delimited by a longitudinal edge 33, parallel to the X direction, shown in [Fig. 6]. The longitudinal edge 33 is preferably formed by the ends of the last boards 31 in the Y direction. Preferably, two joists 10 are provided in a double joist arrangement at this longitudinal edge 33, the joist 10 closest to the longitudinal edge 33 supporting the ends of the boards 31 forming the longitudinal edge 33. The joist 10 closest to the longitudinal edge 33 is intended to support the ends of the boards 31 to prevent them from bending, while the other joist 10 is further from the ends of the boards 31 to be supported directly by the pedestals 40 as described below.

[0041] Preferably, double joists 10 are also provided at the boundary between two rows of boards 31, one of the joists 10 being under the first row, the other joist being under the second row.

[0042] Everywhere else, the joists 10 are advantageously in simple joisting.

[0043] As shown in [Fig.1], the facade surface 35 extends, along the Z direction, between the edge 32 and the floor surface 2, preferably without overflowing from the edge 32 along the X direction.

[0044] As shown in [Fig.6], the facade surface 38 extends, along the Z direction, between the edge 33 and the floor surface 2, preferably without overflowing from the edge 32 along the X direction.

[0045] Each block 40 rests on the floor surface 2 and supports a single joist 10 in single joisting as shown in [Fig.1], or a first joist 10 in double joisting while the other joist 10 is supported by the uprights 20, as shown in [Fig.6]. Alternatively, a single support 40 can support two joists 10 in a double joist system, particularly when the support 40 is not positioned along the longitudinal edge 33. If only one joist 10 in a single joist system is supported by the support 40, the support 40 can also support a strut in addition to the joist 10. For each joist 10, it is advantageous to provide several supports 40 to support that joist 10. Preferably, the supports 40 are configured to maintain the floor surface 30 at a height of less than 1 m relative to the ground surface 2.

[0046] In more detail, the plot 40 includes a base 41, a link 42 and a head 50.

[0047] The base 41 is traversed by a base axis A41 and is configured to rest on the ground surface 2 such that the base axis A41 is perpendicular to ground surface 2. Depending on the horizontality of ground surface 2, the base axis A41 can be parallel to the Z direction, or slightly oblique to the Z direction.

[0048] The link 42 is supported by the base 41, such that the base 41 supports the head 50 via the link 42, so that the head 50 is traversed by the axis of the base A41. The link 42 is configured so that the position of the head 50 relative to the base 41 is adjustable.

[0049] To allow adjustment of the position of the head 50, the connection 42 preferably comprises a base element 43 supported by the base 41 and a head element 44 supporting the head 50 and being supported by the base element 43. The connection 42 preferably comprises a screw and a nut coaxial with the base axis A41 and engaged by screwing into each other along the base axis A41 so that the position of the head 50 relative to the base is adjustable along the base axis A41, i.e., adjustable in height relative to the floor surface 2. The screw belongs to a first element among the base element 43 and the head element 44, while the nut belongs to a second element, distinct from the first element, among the head element 44 and the base element 43.In this case, the base element 43 includes the nut, which is fixedly attached to the base 41 and is coaxial with the axis A41, and the head element 44 includes the screw, which supports the head 50 and is coaxial with the axis A41. The linkage 42 advantageously includes an actuating ring 45 belonging to the head element 44 or to the base element 43, to actuate this element in rotation about the axis A41 relative to the other element 44 or 43, and thus allow adjustment of the position of the head 50 relative to the base 41 along the axis A41, by tightening / loosening the screw and nut. Here, for example, the ring 45 is provided for in the head element 44, that is to say, is . fixedly attached to the screw, by being arranged at an upper end of the head element 44, i.e. opposite the base element 43. In practice the crown 45 is actuable by hand and / or with the aid of an appropriate tool and includes for this purpose, for example, a series of lugs distributed around the axis A41.

[0050] To allow adjustment of the position of the head 50, the linkage 42 preferably includes a ball joint 46, visible in [Fig. 4], through which the linkage 42 supports the head 50. Here, the ball joint 46 belongs to the head element 44, being formed at the upper end of the head element 44. The ball joint 46 is advantageously centered on the axis A41 and allows adjustment of the orientation of the head 50 around the axis A41 and around two other axes perpendicular to the axis A41.

[0051] The head 50 comprises a plate 60 and, preferably, one or more ears 70 fixedly attached to the plate 60.

[0052] The plate 60 comprises a main face 61 and preferably, a lower part 63.

[0053] The plate 60 is transverse with respect to the base axis A41.

[0054] The main face 61 is flat and is crossed, at its center, by a central axis Z61, perpendicular to the main face 61. The central axis Z61 is parallel to the direction Z. The main face 61 is directed in the direction Z. The axis Z61 crosses the base 41, preferably from one side to the other.

[0055] If the ball joint 46 is provided, the axis Z61 passes through the center of the ball joint 46 and, depending on the orientation given to the main face 61 by the ball joint 46, is either oblique with respect to the axis A41, intersecting the axis A41, or coaxial with the axis A41. The ball joint 46 allows a slight obliquity of the axis Z61 with respect to the axis A41 and also allows these axes Z61 and A41 to be coaxial. This makes it possible to compensate for a possible slope of the floor surface 2 with respect to the horizontal plane, so that the platform 60 is oriented horizontally even in this case. In the absence of a ball joint 46, the axes A41 and Z61 are coaxial.

[0056] Each ear 70 protrudes from the main face 61, parallel to the axis Z61, more precisely along the direction Z. Preferably, no other element than the ears 70 protrudes from the main face 61, except for possible raised engravings formed on the surface of the main face 61.

[0057] The pedestal 40 supports the floor surface 30 in that the head 50 supports at least one of the joists 10, whether in single joist arrangement as shown in [Fig.1] or in double joist arrangement for a pedestal 40 along the longitudinal edge 33 as shown in [Fig.6], these joists 10 supporting the floor surface 30. For the case of [Fig.6], the joist closest to the edge 33 is supported by the base 41 via the lateral post 20, as explained below. Each joist 10 supported by the head 50 is in fact supported by the face 61 of the platform 60, parallel to the Z direction and is positioned relative to the head 50 along the X and Z directions by coming to rest laterally on one or both of the ears 70.

[0058] As shown in Figures 1 and 6, lateral uprights 20 are provided along the edges 32 and 33. For the edge 32, the uprights 20 are distributed along the Y direction. For the edge 33, the uprights 20 are distributed along the X direction. Each upright 20 is oriented parallel to the base axis A41 and comprises a lower end 21 and an upper end 22 through which passes an upright axis A20 that is parallel to the base axis A41, i.e., perpendicular to the floor surface 2. Preferably, the upright 20 is centered on the upright axis A20. Parallel to the axis A41, each upright 20 is arranged between the joist 10 and the floor surface 2, being kept at a distance from the floor surface 2 as explained below. Preferably, the upright 20 is fixed to the joist 10, for example by means of a screw which goes through the upright and the joist 10.

[0059] Preferably, as shown in [Fig. 1], for the border 32, the upright 20 is arranged between the end of the joist 10 and the floor surface 2, being in contact with an underside of the joist 10, through which the joist 10 also rests on the head 50. Alternatively, the joist 10 can be provided to be in extreme support along the direction X against the upper end 22 of the upright 20, the upper end 22 then extending to the floor surface 30, or close to the floor surface.

[0060] Along the X direction, the upright 20 is positioned between the post 40 and the facade surface 35. The facade surface 35 is supported, at least in part, by the upright 20, being fixed to the upright 20, for example by means of screws passing through the boards 36. In addition, it is optionally possible to fix the board 36 closest to the edge 32 to the end of the joists 10, thus contributing to supporting the facade surface 35. Since the facade surface 35 is fixed to the uprights 20, it is parallel to the axes A20.

[0061] Preferably, as shown in [Fig. 6], for the edge 33, the stud 20 is arranged between an intermediate portion of the joist 10 closest to the edge 33 and the floor surface 2, in contact with an underside of the joist 10 to support it. In this case, the joist 10 is not supported by the head 50, but is supported directly by the stud 20. Alternatively, the joist 10 closest to the edge 33 may be supported by the head 50 rather than by the stud 20, in the same way as the other joist 10 of the double joist system. Then, the upper end 22 of the stud may extend to, or near, the floor surface 30. of the floor area 30, and that the joist 10 closest to the edge 33 is laterally supported in the opposite direction of Y against the upper end 22 of the post 20.

[0062] Along the Y direction, the upright 20 is positioned between the facade surface 38 and the support 40. The facade surface 38 is supported, at least in part, by the upright 20, being fixed to the upright 20, for example by means of screws passing through the boards 39. In addition, it is optionally possible to fix the board 39 closest to the edge 33 to a lateral face of the joist 10 closest to the edge 33, thus contributing to supporting the facade surface 38. Since the facade surface 38 is fixed to the uprights 20, it is parallel to the axes A20.

[0063] To ensure the positioning of the uprights 20, the pads 40 which are adjacent to one of the facade surfaces 35 and 38 further comprise lower cradles 80 and an adapter 100, comprising an upper cradle 101. As shown in Figures 1 and 6, one of the lower cradles 80 of the pad 40, or the lower cradle 80 of the pad 40, receives the lower end 21 of the upright 20 as support, while the upper cradle 101 of the same pad 40 receives the upper end 22 of the upright 20 as support. This support of the upright 20 on the cradles 80 and 101 ensures that the axis of the upright A20 is parallel to the axis A61 of the base A61, in other words, that the upright 20 is perpendicular to the ground surface 2 on which the pad 40 supporting this upright 20 rests. The support of the upright 20 on the cradle 80 also ensures that the upright 20, in particular the lower end 21, is at a distance from the ground surface 2, parallel to the axis A41.

[0064] The lower cradles 80 can advantageously be provided for all the pads 40, whereas the adapter 100 is preferably provided only for the pads 40 adjacent to one of the front surfaces 35 and 38. As can be seen in Figures 3 and 4, each pad 40 has, for example, two lower cradles 80 spaced a quarter turn apart from each other around the base axis A41, but it would be possible to provide a single lower cradle 80, or more lower cradles, for example three or four lower cradles 80, preferably spaced a quarter turn apart from each other around the axis A41.

[0065] Each lower cradle 80 is fixedly attached to the base 4L. Preferably, a single piece forms both the base 41 and the cradles 80, or even forms in addition the base element 43 of the connection 42.

[0066] The base 41 here includes a support ring 49, which is perpendicular to the axis A41 and through which the base 41 rests flat on the ground surface 2 in the opposite direction to the Z direction. Preferably, each lower cradle 80 is fixedly attached to the support ring 49 by being formed from the support ring 49.

[0067] Preferably, the lower cradle 80 comprises a support face 81, perpendicular to axis A41, supporting the lower end 21 in order to keep the lower end 21 away from the floor surface 2. Preferably, as shown in Figures 3 and 4, the support face 81 is formed by a network of ribs projecting from the support ring 49. The thickness of the ring 49 and of this network of ribs, or more generally, the thickness measured between the lower face of the ring 49 and the support face 81, measured along axis A41, is, for example, a few millimeters, so that the end 21 is kept at this distance from the floor surface 2. This distancing prevents moisture from rising from the floor surface 2 into the raised floor 1, via the upright 20.

[0068] Preferably, as shown in Figures 1 and 6, the facade surfaces 35 and 38 are provided to be supported by the uprights 20 so as to also be distant from the floor surface 2, also to avoid rising damp.

[0069] Preferably, the lower cradle 80 also includes a bearing face 82, referred to as the "lower external radial bearing face," for internal radial support of the lower end 21 of the side post 20. Preferably, the bearing face 82 is formed on a wall that projects from the crown 49 parallel to the axis A41, in the direction of the head 50. This bearing face 82 is oriented radially outwards with respect to the axis A41. In other words, the bearing face 82 is oriented perpendicular to a radius originating from the axis A41 and away from the axis A41. In the case of [Fig.1], the bearing face 82 is oriented along the X direction, i.e. parallel to and in the direction of the facade surface 35. In the case of [Fig.6], the bearing face 82 is oriented in the opposite direction to the Y direction, i.e. parallel to and in the direction of the facade surface 38.The support of the end 21 of the upright against the face 82 ensures that the distance between the upright 20 and the axis A41 is always the same, and thus facilitates the positioning of the upright 20. Preferably, the support face 82 extends over the entire width of the upright 20, or over most of this width, the width being measured here perpendicular to the axis A20 at the height of the end 21.

[0070] Preferably, the lower cradle 80 does not include an orthoradial bearing face for the upright 20, that is to say a surface which would be perpendicular to the faces 81 and 82 and against which the upright 20 would be received in support at the same time as against the faces 81 and 82.

[0071] Preferably, the end 21 is fixed to the cradle 80 by gluing the end 21 to the cradle 80. Preferably, as shown in Figures 3 and 4, recesses 83 are formed in the bearing face 82. The recesses 83, as well as the hollows formed by the network of ribs forming the face 81, advantageously constitute glue traps, suitable for receiving glue to fix the end 21 to the lower cradle 80. The glue in its liquid state seeps into these glue traps so as to form anchors once it hardens.

[0072] The lower cradle 80 and upper cradle 101 are arranged along an axis which is parallel to the axis A41, with the upper cradle 101 between the lower cradle 80 and the main surface 61 of the head 50.

[0073] Preferably, the upper cradle 101 includes a bearing face 102, referred to as the "upper external radial bearing face", for internal radial support of the upper end 22 of the lateral upright 20. This bearing face 102 is oriented radially outwards with respect to the axis A41. In other words, the bearing face 102 is oriented perpendicular to a radius originating from the axis A41 and away from the axis A41. In the case of [Fig.1], the bearing face 102 is oriented along the X direction, i.e. parallel to and in the direction of the facade surface 35. In the case of [Fig.6], the bearing face 102 is oriented in the opposite direction to the Y direction, i.e. parallel to and in the direction of the facade surface 38. Preferably, the face 102 is positioned beyond the connection 42, including beyond the ring 45, from the axis A41.The support of the end 22 of the upright 20 against the face 102 ensures that the distance between the upright 20 and the axis A41 is always the same, and thus facilitates the positioning of the upright 20.

[0074] The bearing faces 82 and 102 are advantageously coplanar when the upright 20 is received by the cradles 80 and 101, and are arranged along an axis which is parallel to the axis A41, with the face 102 between the face 82 and the main surface 61 of the head 50, and even between the base element 43 and the main surface 61 of the head 50.

[0075] Preferably, the bearing face 102 extends over the entire width of the upright 20, or over most of this width, the width being measured here perpendicular to the axis A20 at the height of the end 22.

[0076] The bearing face 102 advantageously comprises two opposing orthoradial ends 103. By "orthoradial" it is understood that the ends 103 are opposite in the direction of the width of the upright 20, that is to say that the ends 103 are distributed along an axis which is both parallel to the face 102 and perpendicular to the axis A41.

[0077] The upper cradle 101 includes a tab 104, which projects radially outwards from one of the orthoradial ends 103 of the bearing face 102. In other words, the tab 104 extends beyond the face 102 from the axis A41. The end 22 of the jamb 20 is received in orthoradial bearing against the mitre 104 while also being received in internal radial bearing against the face 102. In other words, the end 22 is laterally supported against the mitre 104, that is, in a direction parallel to the facade surface 35 or 38 supported by the jamb 20. In the case of [Fig. 1], the end 22 is supported against the mitre in the opposite direction to Y. In the case of [Fig. 6], the end 22 is supported in the opposite direction to X. Thanks In tab 104, the upright 20 is therefore positioned in a third direction of space, namely the orthoradial direction, in addition to the radial direction via faces 82 and 102 and in addition to the axial direction via face 81. The positioning of the upright 20 during installation is therefore particularly precise and repeatable.

[0078] Preferably, no other tab protrudes from the other end 103, to allow the possibility of providing an upright 20 wider than the bearing face 102, which would then cover the end 103 without a tab 104 by extending beyond this end 103, while being orthoradially supported against the tab 104.

[0079] Preferably, the upright 20, which rests on the upper cradle 101, can be fixed to the upper cradle 101, for example, by means of a screw passing through the tab 104. This fixing allows, for example, the upright 20 and the block 40 to be immobilized relative to each other during installation, for example, while waiting for the adhesive applied to the cradle 80 to fix the lower end 21 to harden and / or before the upright 20 is further fixed to the joist 10 against which the upright 20 is already resting, or will rest. As an alternative to fixing by screw, or in addition, the upper cradle 101 and the upright 20 can be fixed by gluing.

[0080] The adapter 100 advantageously comprises, in addition to the upper cradle 101, a fastener 110, through which the adapter is attached to the link 42. The upper cradle 101 is fixedly attached to the fastener 110. The fastener 110 is more clearly visible in Figures 2, 4 and 5. Preferably, the fastener 110 is configured so that the adapter 100 can be detached from the link 42 to which it was attached, i.e. the adapter 100 can be attached to or detached from the block 40 via the fastener 110, depending on the situation. For example, if block 40 does not need to support a post 20, block 40 is advantageously not equipped with adapter 100. Conversely, if block 40 must support a post 20 as shown in figures 1 and 6, block 40 is advantageously equipped with adapter 100. The same block 40 therefore satisfies several uses, facilitating the industrialization of block 40.

[0081] Preferably, to be secured to the link 42, the adapter 100 is preferably secured to the head element 44 via the fastener 110. This allows the cradle 101 to be at a suitable distance from the cradle 80, at the height of the upper end 22 of the upright 20. Preferably, the fastener 110 is received between the ring 45 and the plate 60 when the adapter 100 is secured to the link 42, and is attached to the head element 44 at this point. The fastener 110 is then preferably supported by the head element 44 along the axis A41, preferably by resting on the ring 45, and is also radially retained by the head element 44, preferably by being hooked onto a retaining portion 47 belonging to the head element 44 and visible in [Fig. 4].

[0082] Preferably, the fastener 110 comprises two hooks 111. Each hook 111 is formed by a curved arm, preferably in an arc, towards the other hook 111. The hooks 111 are preferably symmetrical, or at least curved about the same axis which, when the adapter 100 is fixed to the connection 42, is coaxial with the axis A41. Each hook 111 is fixedly attached to the cradle 101 at the base of the hook 111. Preferably, each hook 111 extends along a plane that is perpendicular to the face 102 and to the tab 104. When the adapter 100 is fixed to the connection 42, this plane is perpendicular to the axis A41.

[0083] The retaining portion 47 is fixedly attached to the ring 45 and / or to the element among the screw and nut formed by the head element 44. The retaining portion 47 is preferably formed at an upper end of the head element 44, projecting outwards towards the head 50 parallel to the axis A41. Preferably, the head element 44 is radially arranged between the ball joint 46 and the ring 45. For example, the retaining portion 47 comprises an external annular wall 48, centered on the base axis A41, which projects outwards from the ring 45 along the axis A41, preferably arranged radially between the ball joint 46 and the ring 45. The ring 45, axially recessed relative to the retaining portion 47, extends radially outwards from the wall 48.When the adapter 100 is attached to the link 42, each hook 111 surrounds the retaining portion 47 around the base axis A41, making contact, on the inside of the hook, with the wall 48. The hooks 111 thus grip the retaining portion 47. The hooks 111 thus capture the retaining portion 47 by gripping it, to hold the adapter 100 attached to the link 42. The hooks 111 are also received against the head element 44, in particular against the ring 45, along the axis A41. Preferably, the hooks 111 are also supported, in the opposite direction, against the plate 60, so that the head 50 is held in an orientation where the axes A41 and Z61 are coaxial. In other words, when the adapter 100 is fixed to the link 42, the adapter advantageously neutralizes the mobilities that were permitted by the ball joint 46, if such a ball joint 46 is provided.

[0084] The fastener 110 is configured so that the adapter 100 can be detached by pulling the adapter 100 radially outwards from the axis A41. In doing so, the hooks 111 elastically separate from each other until they pass the retaining portion 47, thus releasing the adapter 100 from the connection 42. Conversely, the fastener 110 is configured so that the adapter 100 can be secured by inserting the fastener 110 radially inwards, between the ring 45 and the plate 60. In doing so, the hooks 111 elastically separate from each other until they pass the retaining portion 47. Once the retaining portion 47 has been passed, the hooks 111 return elastically to their original position and thus capture the retaining part 47 as described above.

[0085] Preferably, when the adapter 100 is fixed to the link 42, the adapter 100 is axially fixed relative to the link 42 and is nevertheless pivotable about the axis A41 relative to the link 42 and to the base 41, so as to assume distinct orientations about the axis A41. In at least some of these distinct positions, the face 102 is aligned with the face 82 of one or the other of the lower cradles 80, as desired. Thus, the coplanarity of the faces 102 and 82 is ensured only when the adapter 100 is in the correct orientation about the axis A41. In practice, the annular shape of the retaining portion 47 allows this pivoting through cooperation with the hooks 111.Alternatively, the adapter 100 is axially fixed relative to the link 42 and is not pivotal about the axis A41, but can nevertheless assume several distinct orientations about the axis A41 in that it can be detached, changed orientation, and then reattached in that orientation. In at least some of these distinct positions, or even in all of these distinct orientations, the face 102 is aligned with the face 82 of either of the lower cradles 80, as desired.

[0086] For the block 40, having several lower cradles 80 makes the block 40 versatile, allowing the choice of which lower cradle 80 will receive the upright 20 in support, the orientation of the adapter 100 then being adapted accordingly.

[0087] Alternatively, a single hook 111 is provided, which surrounds the retaining part 47 around the base axis A41, so as to capture said retaining part 47 when the adapter is attached to the link 42.

[0088] Alternatively, the adapter 100 is fixed, and optionally detachable, from the head 50 rather than from the link 42, according to the same principles as those described above. In this case, for example, the head 50 includes the retaining portion 47, projecting towards the link 42 from the plate 60 or the lower part 63, and to which the fastener 110 can be fixed.
