Le plot (2) d'ancrage au sol est réalisé en une matière métallique suffisamment solide revêtue d'un revêtement anti corrosion graissé à vie pour permettre un ancrage optimale et pour résister, aux contraintes mécaniques générées par l'équipement à installer, et aux intempéries. Le plot (2) d'ancrage est creux et de forme générale cylindrique avec une paroi de fond (2a) et une ouverture supérieure (2b) pour la réception de l'embout (3) de raccordement. Le plot (2) d'ancrage est destiné à être encastré et fixé dans le sol (non représenté). Il comprend en outre une collerette (4) pour reposer sur le sol, ladite collerette (4) étant, lorsque le plot (2) est ancré dans le sol, à l'affleurement de la surface du sol. Cette collerette (4) permet notamment de limiter l'enfoncement du plot (2) dans le sol et comprend d'autres avantages qui seront décrits plus bas. Des ailettes (5) anti-rotation se prolongent longitudinalement vers le bas à partir de ladite collerette (4) afin de limiter la rotation du plot (2) d'ancrage lorsque celui-ci est ancré dans le sol. L'ancrage du plot (2) est optimal.The ground anchor pad (2) is made of a sufficiently strong metallic material coated with an anti-corrosion coating lubricated for life to allow optimal anchoring and to withstand the mechanical stresses generated by the equipment to be installed, and severe weather. The anchoring stud (2) is hollow and generally cylindrical in shape with a bottom wall (2a) and an upper opening (2b) for receiving the connecting end (3). The stud (2) is anchored to be recessed and fixed in the ground (not shown). It further comprises a flange (4) for resting on the ground, said flange (4) being, when the stud (2) is anchored in the ground, the outcrop of the ground surface. This collar (4) allows in particular to limit the depression of the stud (2) in the ground and includes other advantages which will be described below. Anti-rotation fins (5) extend longitudinally downwardly from said flange (4) to limit the rotation of the anchor stud (2) when it is anchored in the ground. The anchoring of the stud (2) is optimal.

L'embout (3) de raccordement comprend une gorge (7) ménagée sur sa paroi externe à une hauteur déterminée, en dessous de la zone de rupture (6). Cette gorge (7) permet le verrouillage dudit embout (3) dans le plot (2) d'ancrage tel que décrit plus bas.The connecting end (3) comprises a groove (7) formed on its outer wall at a given height, below the rupture zone (6). This groove (7) allows the locking of said tip (3) in the stud (2) of anchoring as described below.
L'embout (3) de raccordement comprend en outre, un profil sous forme par exemple d'une échancrure (8) longitudinale ménagée sur son extrémité inférieure. Cette échancrure (8) permet le réglage de l'orientation de l'embout (3) dans le plot (2) d'ancrage tel que décrit plus bas.The connection end piece (3) further comprises a profile in the form of, for example, a longitudinal indentation (8) formed on its lower end. This notch (8) allows the adjustment of the orientation of the tip (3) in the stud (2) anchoring as described below.
L'embout (3) ainsi solidarisé à l'équipement est alors apte à être engagé et verrouillé à l'intérieur du plot (2) d'ancrage pour l'ancrage temporaire au sol dudit équipement. L'embout (3) est engagé à l'intérieur du plot (2) jusqu'à la zone de rupture (6).The end piece (3) thus secured to the equipment is then adapted to be engaged and locked inside the anchor pad (2) for temporarily anchoring the said equipment to the ground. The tip (3) is engaged inside the stud (2) to the rupture zone (6).

Le fût fixe (9) est idéalement également réalisé en une matière métallique solide revêtue d'un revêtement anti corrosion graissé à vie. Ledit fût fixe (9) est creux et de forme générale cylindrique et est destiné à recevoir l'embout (3) de raccordement universel. Le diamètre interne du fût fixe (9) est sensiblement égal au diamètre externe de l'embout (3) de raccordement avec un léger jeu de manière à permettre le coulissement de l'embout (3) dans le fût fixe (9).The fixed shaft (9) is ideally also made of a solid metal material coated with a lubricated anti-corrosion coating for life. Said fixed shaft (9) is hollow and generally cylindrical in shape and is intended to receive the end piece (3) universal connection. The internal diameter of the fixed shaft (9) is substantially equal to the outer diameter of the connecting end (3) with a slight clearance so as to allow the sliding of the end piece (3) in the fixed shaft (9).
Le plot (2) d'ancrage comprend une plaque de fond (2c) et le fond du fût fixe (9) est solidarisé à une douille (11) de fixation elle-même solidarisée à ladite plaque de fond (2c) au moyen d'un écrou de fixation (11a). Une rondelle d'orientation (12) est agencée entre l'écrou (11a) et la douille (11) tel que décrit plus bas.The anchoring stud (2) comprises a base plate (2c) and the bottom of the fixed shaft (9) is secured to a fastening bushing (11) which is itself secured to said base plate (2c) by means of a fixing nut (11a). An orientation washer (12) is arranged between the nut (11a) and the sleeve (11) as described below.
Le fût mobile (10) est idéalement également réalisé en une matière métallique solide revêtue d'un revêtement anti corrosion graissé à vie. Ledit fût mobile (10) est creux et de forme générale cylindrique et est monté avec capacité de coulissement autour du fût fixe (9) entre une position de verrouillage de l'embout (3) dans le plot (2) et une position de déverrouillage. Le diamètre externe du fût mobile (10) est sensiblement égal au diamètre interne du plot (2) d'ancrage avec un léger jeu pour permettre le coulissement dudit fût mobile (10) dans le plot (2) d'ancrage.The mobile shaft (10) is ideally also made of a solid metal material coated with a lubricated anti-corrosion coating for life. Said mobile drum (10) is hollow and generally cylindrical in shape and is mounted with sliding capacity around the fixed shaft (9) between a locking position of the end piece (3) in the stud (2) and an unlocking position . The outer diameter of the mobile drum (10) is substantially equal to the inner diameter of the anchor pad (2) with a slight clearance to allow the sliding of said mobile drum (10) in the stud (2) anchoring.
Le fût mobile (10) comprend une partie supérieure (10a) de diamètre interne sensiblement égal au diamètre externe du fût fixe (9) avec un léger jeu de manière à permettre le coulissement dudit fût mobile (10) par rapport au fût fixe (9), et une partie inférieure (10b) de diamètre interne supérieur au diamètre externe du fût fixe (9) de manière à définir un espace (10d) entre lesdits fûts, les deux parties (10a, 10b) étant délimitées par une pente (10c).The mobile shaft (10) comprises an upper portion (10a) of internal diameter substantially equal to the outer diameter of the fixed shaft (9) with a slight clearance so as to allow said mobile shaft (10) to slide relative to the stationary shaft (9). ), and a lower portion (10b) of inner diameter greater than the outer diameter of the fixed shaft (9) so as to define a space (10d) between said barrels, the two parts (10a, 10b) being delimited by a slope (10c). ).
Le coulissement du fût mobile (10) autour du fût fixe (9) se fait à l'encontre d'un organe élastique (13). L'organe élastique se présente sous la forme d'un ressort (13) hélicoïdal agencé autour du fût fixe (9) et logé dans l'espace (10d) défini entre les deux fûts (9, 10). Le ressort (13) travaille en compression entre deux bagues de maintien (13a, 13b), elles-mêmes en butée contre, d'une part, un épaulement annulaire (14) défini sur la paroi externe du fût fixe (9), et, d'autre part, sur une rondelle support (15) agencée dans une rainure annulaire interne ménagée dans la paroi interne de l'extrémité inférieure du fût mobile (10). Le travail du ressort (13) tend à pousser et maintenir le fût mobile (10) vers le bas dans sa position de verrouillage.Sliding of the mobile shaft (10) around the fixed shaft (9) is against an elastic member (13). The elastic member is in the form of a helical spring (13) arranged around the fixed shaft (9) and housed in the space (10d) defined between the two barrels (9, 10). The spring (13) works in compression between two retaining rings (13a, 13b), themselves abutting against, on the one hand, an annular shoulder (14) defined on the outer wall of the fixed shaft (9), and on the other hand, on a support washer (15) arranged in an internal annular groove formed in the inner wall of the lower end of the mobile shaft (10). The work of the spring (13) tends to push and hold the mobile shaft (10) downwards in its locking position.
Les moyens de verrouillage/déverrouillage de l'embout (3) de raccordement universel dans le plot (2) d'ancrage au sol comprennent au moins un orifice (16), quatre dans la forme de réalisation illustrée aux figures annexées, ménagés dans l'épaisseur de la paroi du fût fixe (9), au-dessus de l'épaulement (14) formant butée pour la bague de maintien (13a) du ressort (13). Les quatre orifices (16) sont diamétralement opposés et régulièrement répartis sur la périphérie du fût fixe (9).The locking / unlocking means of the universal connection end piece (3) in the ground anchor stud (2) comprise at least one orifice (16), four in the embodiment illustrated in the appended figures, provided in FIG. the thickness of the wall of the fixed shaft (9), above the shoulder (14) forming a stop for the retaining ring (13a) of the spring (13). The four orifices (16) are diametrically opposed and regularly distributed over the periphery of the fixed shaft (9).
Chacun des orifices (16) reçoit une bille (17) escamotable de verrouillage de diamètre sensiblement supérieur au diamètre de l'orifice (16) de sorte que la bille (17) est apte à faire saillie, en position de verrouillage, à l'intérieur dudit fût sans traverser entièrement ledit orifice (16).Each of the orifices (16) receives a ball (17) retractable locking diameter substantially greater than the diameter of the orifice (16) so that the ball (17) is adapted to protrude, in the locking position, to the interior of said barrel without completely traversing said orifice (16).
L'agencement du fût mobile (10) par rapport au fût fixe (9) est tel que les orifices (16) recevant les billes (17) escamotables se trouvent au niveau de la partie inférieure du fût mobile (10). En position de verrouillage du fût mobile (10), celui-ci coopère avec la bille (17) de sorte que la pente (10c), reliant la partie supérieure (10a) du fût mobile (10) à la partie inférieure (10b), vienne en butée contre les billes (17) escamotables et pousse celles-ci dans les orifices (16) respectifs de sortes que lesdites billes (17) font saillies à l'intérieur du fût fixe (9). Le fût mobile (10) et lesdites billes (17) sont donc en position de verrouillage.The arrangement of the mobile shaft (10) relative to the fixed shaft (9) is such that the orifices (16) receiving the retractable balls (17) are at the lower part of the mobile shaft (10). In the locking position of the mobile drum (10), it cooperates with the ball (17) so that the slope (10c), connecting the upper part (10a) of the mobile drum (10) to the lower part (10b) , abuts against the retractable balls (17) and pushes them into the orifices (16) of respective kinds that said balls (17) project inside the fixed shaft (9). The mobile shaft (10) and said balls (17) are therefore in the locking position.

La bague (18) permet de faire passer le fût mobile (10) dans sa position de déverrouillage. Elle comprend à cet effet, des agencements pour coopérer avec l'outil (19) de déverrouillage. Les agencements se présentent sous la forme d'une nervure (18c) annulaire formant crochet.The ring (18) makes it possible to move the mobile drum (10) into its unlocked position. It comprises for this purpose, arrangements for cooperating with the tool (19) for unlocking. The arrangements are in the form of an annular rib (18c) forming a hook.

Le déverrouillage se fait par un seul opérateur à l'aide de l'outil (19) spécifique. L'opérateur actionne idéalement l'outil (19) à l'aide de son pied et garde ses mains libres pour retirer l'équipement. Lorsque l'opérateur relâche la pression du pied, le fût mobile (10) est forcé par le ressort (13) à retourner dans sa position de verrouillage et est maintenu dans cette position, c'est-à-dire la bague (18) en butée sur la collerette (4) et la pente (10c) en butée sur les billes (17) escamotables.Unlocking is done by a single operator using the specific tool (19). The operator ideally activates the tool (19) with his foot and keeps his hands free to remove the equipment. When the operator releases the pressure of the foot, the movable shaft (10) is forced by the spring (13) to return to its locking position and is maintained in this position, that is to say the ring (18) abutting on the flange (4) and the slope (10c) abutting on the balls (17) retractable.
Lorsqu'un opérateur souhaite ancrer temporairement un équipement dans le sol, équipé de l'embout (3) de raccordement universel, celui-ci ne nécessite pas d'utiliser l'outil (19) de déverrouillage pour passer préalablement le fût mobile (10) dans sa position de déverrouillage. En effet, la douille (11) solidaire du fond du fût fixe (9) est réalisée dans une matière absorbant les chocs, et l'extrémité inférieure de l'embout (3) de raccordement est biseautée. De cette manière, lorsque l'embout (3) est engagé à l'intérieur du fût fixe (9), la partie biseautée (3b) dudit embout (3) vient en butée contre les billes (17) escamotables qui sont en position de verrouillage. Lorsqu'une pression vers le bas est exercée sur l'embout (3), la douille (11) se déforme et s'aplatit légèrement de sorte que le fût fixe (9) se déplace légèrement vers le bas, à l'encontre de la force de compression du ressort (13), et suffisamment pour que les billes (17) escamotables soient au niveau de l'espace (10c) défini entre les deux fûts (9, 10), et poussées dans celui-ci par la partie biseautée (3b) de l'embout (3). L'embout (3) est alors engagé dans le fût fixe (9) jusqu'à ce que les billes (17) escamotables soient libérées et pénètrent partiellement dans la gorge (7) annulaire dudit embout (3) pour le verrouillage de celui-ci.When an operator wishes to temporarily anchor a piece of equipment in the ground, equipped with the end piece (3) for universal connection, it does not require the use of the unlocking tool (19) to previously pass the mobile drum (10). ) in its unlocking position. Indeed, the sleeve (11) secured to the bottom of the fixed shaft (9) is made of a shock-absorbing material, and the lower end of the connecting piece (3) is tapered. In this way, when the end piece (3) is engaged inside the fixed barrel (9), the bevelled part (3b) of said end piece (3) abuts against the retractable balls (17) which are in position locking. When a downward pressure is exerted on the tip (3), the sleeve (11) deforms and flattens slightly so that the fixed shaft (9) moves slightly downwards, against the compression force of the spring (13), and sufficiently so that the retractable balls (17) are at the space (10c) defined between the two drums (9, 10), and pushed into it by the part beveled (3b) of the tip (3). The tip (3) is then engaged in the fixed shaft (9) until the retractable balls (17) are released and partially penetrate into the annular groove (7) of said tip (3) for the locking of the latter. this.
La nervure annulaire (18c) formant crochet de la bague (18) de déverrouillage permet, lorsque celle-ci ne reçoit pas l'outil (19), et lorsqu'aucun embout (3) de raccordement n'est engagé dans le plot (2) d'ancrage, de recevoir un bouchon de protection (non représenté) pour le plot (2) d'ancrage.The annular rib (18c) forming a hook of the unlocking ring (18) makes it possible, when the latter does not receive the tool (19), and when no coupling end (3) is engaged in the stud ( 2) anchoring, to receive a protective cap (not shown) for the stud (2) anchoring.
Concernant l'orientation axiale de l'embout (3) de raccordement par rapport au plot (2) d'ancrage, celle-ci est réalisée comme suit. Il suffit à l'opérateur, lorsqu'aucun embout (3) n'est encore engagé dans le fût fixe (9), de dévisser légèrement l'écrou (11a) au fond dudit fût fixe (9) de manière à laisser libre la rotation de la rondelle d'orientation (12). L'opérateur insère ensuite l'embout (3) de raccordement universel dans le fût fixe (9) et fait coopérer ladite rondelle d'orientation (12) avec l'échancrure (8) longitudinale présente à l'extrémité inférieure dudit embout (3). En d'autres termes, une partie de la rondelle d'orientation (12) est apte à pénétrer et venir en prise dans ladite échancrure (8). L'opérateur oriente ensuite l'équipement, et donc l'embout (3) de raccordement à sa guise, orientant en même temps la rondelle d'orientation (12), et retire ensuite l'embout (3) à l'aide de l'outil (19) de déverrouillage. L'opérateur serre enfin l'écrou (11a) de fixation en tâchant de garder l'orientation de la rondelle d'orientation (12). L'orientation de l'embout (3) est réglée et conservée.Concerning the axial orientation of the connection end piece (3) with respect to the anchoring stud (2), this is done as follows. It suffices for the operator, when no tip (3) is still engaged in the fixed shaft (9), to slightly unscrew the nut (11a) at the bottom of said fixed shaft (9) so as to leave free the rotation of the orientation washer (12). The operator then inserts the endpiece (3) of universal connection into the fixed shaft (9) and makes said orientation washer (12) cooperate with the longitudinal indentation (8) present at the lower end of said endpiece (3). ). In other words, a portion of the orientation washer (12) is able to penetrate and engage in said notch (8). The operator then directs the equipment, and therefore the connecting end piece (3) as he wishes, at the same time orienting the orientation washer (12), and then removes the end piece (3) with the aid of the unlocking tool (19). The operator finally tightens the nut (11a) fixing trying to keep the orientation of the orientation washer (12). The orientation of the tip (3) is set and maintained.
Comme il ressort (13) de ce qui précède, l'ensemble (1) permet de rendre amovible tout équipement monté en bout de l'embout (3) de raccordement universel. Cela permet de pouvoir remodeler les espaces urbains en fonction des évènements, saisons ou besoins techniques. La mise en place est simple, rapide et sécurisé. La présence d'un seul opérateur est nécessaire pour effectuer les opérations de verrouillage/déverrouillage de l'équipement considéré. Le déverrouillage ne peut être effectué qu'avec l'outil spécifique (19).As is apparent (13) from the foregoing, the assembly (1) makes it possible to make any equipment mounted at the end of the end piece (3) of universal connection removable. This makes it possible to remodel urban spaces according to events, seasons or technical needs. The implementation is simple, fast and secure. The presence of a single operator is necessary to perform the locking / unlocking operations of the equipment in question. Unlocking can only be done with the specific tool (19).
