Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

La présente invention concerne : (a) un embout de plinthe destiné à être agencé à une extrémité d'une plinthe et permettant de fixer celle-ci sur un montant d'un échafaudage, (b) une plinthe dont chaque extrémité est conçue pour recevoir cet embout, ainsi (c) qu'un échafaudage comportant cette plinthe et cet embout.The present invention relates to: (a) a plinth endpiece for arranging at one end of a plinth and for securing it to a scaffolding post, (b) a skirting board each end of which is adapted to receive this end, and (c) a scaffolding comprising the skirting board and this end piece.

ARRIÈRE PLAN TECHNOLOGIQUE DE L'INVENTIONBACKGROUND OF THE INVENTION

Afin de satisfaire aux normes de sécurité, les planchers des échafaudages doivent être munis de plinthes le long de leurs bords. Ces plinthes sont destinées notamment à éviter la chute d'outils ou autres.In order to meet safety standards, scaffolding floors must have skirting boards along their edges. These baseboards are intended in particular to avoid the fall of tools or others.

Les plinthes ont longtemps été constituées par des planches fixées, souvent de manière rudimentaire, aux montants des échafaudages, notamment par des serre-joints.The skirting boards have for a long time been constituted by fixed planks, often in a rudimentary manner, to the scaffolding posts, in particular by clamps.

Un dispositif de fixation rapide plus adapté à cette fonction est décrit dans la demande de brevet français FR 2.494.752 , déposée par la société SOMEFRAN, qui a été publiée le 28 mai 1982.A quick fastener more suited to this function is described in the patent application French FR 2.494.752 , filed by SOMEFRAN, which was published on May 28, 1982.

Mais le dispositif décrit n'est qu'une simple amélioration du principe du serre-joint, qui ne tire donc pas bénéfice des caractéristiques des planchers constitués de profilés métalliques des échafaudages modulaires modernes.But the device described is a simple improvement of the principle of the clamp, which does not take advantage of the characteristics of the floors made of metal profiles of modern modular scaffolds.

Le brevet japonais JP 11-141116 au nom de la société KAWATETSU KIZAI KOGYO, publié le 25 mai 1999, concerne une plinthe pouvant être facilement fixée sur un échafaudage standard. La plinthe, formée d'un profilé métallique de section en C, comporte des embouts amovibles insérés à chaque extrémité dans les ailes du profilé.The patent Japanese JP 11-141116 on behalf of KAWATETSU KIZAI KOGYO, published on May 25, 1999, concerns a plinth that can be easily attached to a standard scaffold. The skirting board, formed of a C-section metal section, has removable end-pieces inserted at each end into the flanges of the section.

Chacun des embouts comporte une agrafe unique en U s'étendant perpendiculairement au plan de la plinthe et destinée à être engagée sur les montants tubulaires verticaux de l'échafaudage.Each end has a single U-shaped clip extending perpendicularly to the plane of the plinth and intended to be engaged on the vertical tubular uprights of the scaffold.

Chaque embout présente une entaille longitudinale décalée par rapport à l'axe de la plinthe, et une languette de forme complémentaire de cette entaille, agencée symétriquement, sur laquelle est fixée la base de l'agrafe. De la sorte, des plinthes identiques peuvent être assemblées jointivement bout à bout en s'appuyant sur les montants de l'échafaudage.Each endpiece has a longitudinal notch offset from the axis of the plinth, and a tongue of complementary shape of this notch, arranged symmetrically, on which is fixed the base of the clip. In this way, identical skirting boards can be joined together end to end by leaning on the uprights of the scaffolding.

L'extension latérale de l'agrafe permet un positionnement du bord inférieur de la plinthe le long du bord extérieur du plancher sans laisser d'espace.The lateral extension of the clip allows positioning of the bottom edge of the plinth along the outer edge of the floor without leaving any space.

Ce dispositif de fixation d'une plinthe présente l'avantage de ne nécessiter qu'une seule sorte d'embout amovible.This attachment device of a plinth has the advantage of requiring only one kind of removable tip.

Toutefois, l'embout décrit ne comporte qu'une seule agrafe rivetée. De plus, l'ensemble étant composite et métallique, il peut être sujet à la corrosion. De ce fait, cet embout, malgré sa structure complexe, reste peu fiable. Enfin, les agrafes latérales présentent l'inconvénient de ne permettre qu'un blocage de la plinthe vers l'extérieur, par les montants.However, the described tip has only one riveted staple. In addition, the assembly being composite and metallic, it can be subject to corrosion. Because of this, this tip, despite its complex structure, remains unreliable. Finally, the lateral staples have the disadvantage of only allowing a blocking of the plinth outwards, by the amounts.

Les documents cités ci-dessus montrent donc que des embouts de plinthes sont connus de l'état de la technique.The documents cited above therefore show that end caps baseboards are known from the state of the art.

Mais aucune solution divulguée ne semble présenter le degré de simplicité et de robustesse souhaitable.But no disclosed solution seems to present the degree of simplicity and robustness desirable.

DESCRIPTION GÉNÉRALE DE L'INVENTIONGENERAL DESCRIPTION OF THE INVENTION

La présente invention vise donc l'amélioration d'un embout de plinthe.The present invention therefore aims to improve a baseboard end.

Cet embout est du type de ceux comportant un élément de base d'une forme générale s'inscrivant dans un parallélépipède.This tip is of the type of those comprising a basic element of a general shape in a parallelepiped.

Cet élément de base est destiné à être emboîté longitudinalement par sa face arrière à une extrémité de la plinthe de telle manière que ses faces longitudinales et latérales soient respectivement en vis-à-vis des surfaces longitudinales et latérales de la plinthe.This base element is intended to be fitted longitudinally by its rear face at one end of the plinth so that its longitudinal and lateral faces are respectively vis-à-vis the longitudinal and lateral surfaces of the plinth.

L'élément de base est muni d'au moins deux pattes, destinées à être engagées de part et d'autre d'un montant vertical de l'échafaudage.The base element is provided with at least two legs, intended to be engaged on both sides of a vertical amount of scaffolding.

L'embout de plinthe selon l'invention est remarquable en ce que les pattes sont agencées sur la face avant de l'élément de base dans une direction longitudinale, de part et d'autre d'un plan prédéterminé parallèle aux faces longitudinales et déporté par rapport au plan de symétrie longitudinal de cet élément de base, et en ce que lesdites pattes présentent des projections, sur un plan de projection parallèle aux faces latérales de l'élément de base, symétriques par rapport à la trace de ce plan prédéterminé sur le plan de projection.The skirting tip according to the invention is remarkable in that the lugs are arranged on the front face of the base member in a longitudinal direction, on either side of a predetermined plane parallel to the longitudinal faces and offset relative to the longitudinal plane of symmetry of this base element, and in that said lugs have projections, on a plane of projection parallel to the lateral faces of the base element, symmetrical with respect to the trace of this predetermined plane on the projection plan.

Ce plan prédéterminé est préférentiellement confondu avec l'une des faces longitudinales de l'élément de base.This predetermined plane is preferably coincident with one of the longitudinal faces of the base element.

De préférence, les pattes sont agencées le long de la face avant alternativement de part et d'autre du plan prédéterminé.Preferably, the tabs are arranged along the front face alternately on either side of the predetermined plane.

Ces pattes sont aussi avantageusement en nombre pair, de préférence au nombre de quatre.These tabs are also advantageously in even numbers, preferably four in number.

Elles sont préférentiellement renforcées par des nervures perpendiculaires à leurs surfaces s'appuyant sur l'élément de base.They are preferably reinforced by ribs perpendicular to their surfaces based on the base element.

Fort avantageusement, l'élément de base de l'embout de plinthe selon l'invention comporte un évidement interne de forme complémentaire de l'extrémité de la plinthe.Advantageously, the base element of the baseboard endpiece according to the invention comprises an internal recess complementary shape of the end of the plinth.

De préférence, l'élément de base est ainsi formé d'un boîtier ouvert sur la face arrière, les parois du boîtier présentant une épaisseur constante.Preferably, the base member is thus formed of an open housing on the rear face, the walls of the housing having a constant thickness.

On tire bénéfice du fait que l'embout selon l'invention est constitué d'une seule pièce de matière plastique moulée, de préférence de PVC.It benefits from the fact that the tip according to the invention consists of a single piece of molded plastic material, preferably PVC.

L'invention concerne aussi une plinthe d'échafaudage adaptée à la mise en place d'un embout de plinthe, comportant un élément de base destiné à être emboîté longitudinalement à l'extrémité de la plinthe, embout de plinthe qui est conforme à l'une quelconque des caractéristiques ci-dessus.The invention also relates to a scaffold skirting adapted to the implementation of a baseboard endpiece, comprising a base element intended to be fitted longitudinally at the end of the skirting board, baseboard endpiece which is in accordance with the any of the above features.

Cette plinthe est remarquable en ce qu'elle est formée d'un profilé présentant une première section droite de forme complémentaire, au moins partiellement, d'une seconde section droite de cet élément de base.This skirting board is remarkable in that it is formed of a section having a first cross-section of complementary shape, at least partially, of a second cross-section of this base element.

Est également visé par l'invention, un échafaudage comprenant au moins un montant vertical remarquable en ce qu'il comprend en outre au moins une plinthe du type décrit ci-dessus, fixée à ce montant par un embout de plinthe ayant les caractéristiques indiquées précédemment.Is also covered by the invention, a scaffold comprising at least a vertical upright remarkable in that it further comprises at least one skirting board of the type described above, fixed to this amount by a plinth end having the characteristics indicated above .

Ces quelques spécifications essentielles rendent évidents pour l'homme de métier les avantages apportés par cet embout de plinthe par rapport à l'état de la technique antérieur.These few essential specifications make it obvious to those skilled in the art the advantages provided by this plinth tip compared to the state of the prior art.

Les spécifications détaillées de l'invention sont données dans la description qui suit en liaison avec les dessins ci-annexés. Il est à noter que ces dessins n'ont d'autre but que d'illustrer le texte de la description et qu'ils ne constituent en aucune sorte une limitation de la portée de l'invention.The detailed specifications of the invention are given in the following description in conjunction with the accompanying drawings. It should be noted that these drawings have no other purpose than to illustrate the text of the description and that they do not constitute in any way a limitation of the scope of the invention.

DESCRIPTION DU MODE DE RÉALISATION PRÉFÉRÉ DE L'INVENTIONDESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION

Le mode de réalisation préféré de l'invention concerne un embout monobloc en PVC et une plinthe au profil spécifique.The preferred embodiment of the invention relates to a one-piece PVC end piece and a skirting board with a specific profile.

La Figure 1 montre bien un tel embout 1 comportant un élément de base 2 de la forme générale d'un parallélépipède rectangle ABCDEFGH muni de pattes 3,4, respectivement inférieures et supérieures, sur sa face avant EFGH. Figure 1 shows such a tip 1 comprising a base member 2 of the general shape of a rectangular parallelepiped ABCDEFGH provided with lugs 3,4, respectively lower and upper on its front face EFGH.

Les autres faces de ce parallélépipède ABCDEFGH sont, respectivement, les faces longitudinales ABFE et DCGH, les faces latérales AEHD et BFGC et la face arrière ABCD.The other faces of this parallelepiped ABCDEFGH are, respectively, the longitudinal faces ABFE and DCGH, the side faces AEHD and BFGC and the rear face ABCD.

Les pattes 3,4 en forme de lame sont renforcées par des nervures 5 perpendiculaires à leurs surfaces et s'appuyant sur la face longitudinale ABFE de l'élément de base 2 pour ce qui est des pattes supérieures 4 et sur la face avant EFGH dudit élément 2 pour ce qui est des pattes inférieures 3.The lugs 3,4 in the form of a blade are reinforced by ribs 5 perpendicular to their surfaces and resting on the longitudinal face ABFE of the base element 2 as regards the upper lugs 4 and on the front face EFGH of said Element 2 for the lower legs 3.

Les pattes 3,4 sont avantageusement au nombre de quatre, s'étendant alternativement au dessous et au dessus de la face longitudinale supérieure ABFE de l'élément de base 2, symétriquement par rapport au plan que forme cette face ABFE.The legs 3,4 are advantageously four in number, extending alternately below and above the face longitudinal upper ABFE of the base member 2, symmetrically with respect to the plane formed by this ABFE face.

Cette disposition symétrique est bien visible sur la Figure 3, présentant une vue en coupe transversale selon III-III de l'embout 1 au niveau d'une patte inférieure 3, coupe qui est effectuée légèrement en avant de la nervure de renforcement 5.This symmetrical arrangement is clearly visible in FIG. 3, having a cross-sectional view along III-III of the tip 1 at a lower tab 3, which section is made slightly in front of the reinforcing rib 5.

Les pattes 3,4 forment, en projection sur un plan parallèle aux faces latérales AEHD, BFGC de l'élément de base 2, un V ouvert vers l'avant.The tabs 3,4 form, in projection on a plane parallel to the side faces AEHD, BFGC of the base member 2, a V open towards the front.

Les projections des pattes 3,4 sur un tel plan de projection sont bien évidemment symétriques.The projections of the legs 3,4 on such a projection plane are obviously symmetrical.

Les parties extrémales respectivement 6,7 des pattes 3,4 s'étendent parallèlement aux faces longitudinales ABFE,DCGH de l'élément de base 2.The end portions 6.7 and respectively of the tabs 3.4 extend parallel to the longitudinal faces ABFE, DCGH of the base member 2.

Les pattes 3,4 représentées comportent aussi à leurs bases des zones de transition respectivement 8,9 s'étendant vers l'avant dans le plan de la face supérieure ABFE de l'élément de base 2.The tabs 3,4 shown also have at their bases transition zones 8,9 respectively extending forwards in the plane of the upper face ABFE of the base element 2.

En variante, ces zones de transition 8,9 sont supprimées, et l'embout est alors de dimension plus réduite.In a variant, these transition zones 8, 9 are eliminated, and the tip is then of smaller size.

Comme le montre aussi la Figure 3, l'élément de base 2 est formé d'un boîtier ABCDEFGH, ouvert sur la face arrière ABCD, dont les parois présentent une épaisseur constante.As also shown in Figure 3, the base member 2 is formed of an ABCDEFGH housing, open on the rear face ABCD, whose walls have a constant thickness.

Typiquement, les dimensions de l'embout 1 sont adaptées aux caractéristiques dimensionnelles d'un échafaudage standard où sont mis en oeuvre des montants verticaux tubulaires 12 d'un diamètre de 50 mm.Typically, the dimensions of the nozzle 1 are adapted to the dimensional characteristics of a standard scaffold where are implemented vertical tubular uprights 12 with a diameter of 50 mm.

De préférence, l'écartement e des pattes 3,4 est de 52 mm, les parties extrémales 6,7 des pattes 3,4 ont une longueur de 20 mm, et les parties médianes respectivement 10,11 desdites pattes 3,4 font un angle de 45° avec les zones de transition 8, 9.Preferably, the spacing e of the tabs 3,4 is 52 mm, the end portions 6,7 of the tabs 3,4 have a length of 20 mm, and the median portions respectively 10,11 of said tabs 3,4 make a 45 ° angle with transition zones 8, 9.

De la sorte, un embout 1 ayant ces dimensions s'engage avec un peu de jeu légèrement au-delà d'un plan diamétral d'un montant 12 standard comme le montrent bien les Figures 2 et 4. In this way, a tip 1 having these dimensions engages with a little play slightly beyond a diametral plane of a standard amount 12 as shown in Figures 2 and 4.

La longueur de l'embout 1, c'est-à-dire la distance entre le plan des extrémités libres des pattes 3,4 et la face arrière ABCD est typiquement de 105 mm dans la version longue préférée, et de 85 mm dans la variante courte.The length of the tip 1, that is to say the distance between the plane of the free ends of the tabs 3,4 and the rear face ABCD is typically 105 mm in the preferred long version, and 85 mm in the short variant.

L'alternance des pattes 3,4 en position inférieure et en position supérieure par rapport à une face longitudinale ABFE, et la limitation de l'engagement sur le montant 12 à un demi-diamètre de ce montant 12, permet de n'utiliser qu'un seul modèle d'embout 1 pour fixer deux plinthes 13 identiques sur un même montant 12 comme le montre la Figure 2. The alternation of the tabs 3,4 in the lower position and in the upper position with respect to a longitudinal face ABFE, and the limitation of the engagement on the upright 12 to a half-diameter of this upright 12, makes it possible to use only a single model tip 1 to fix two baseboards 13 identical on the same amount 12 as shown in Figure 2.

Le déport du plan de symétrie ABFE des pattes 3,4 par rapport au plan de symétrie longitudinal du boîtier ABCDEFGH permet de déporter l'axe X-X d'une plinthe 13 en direction du plateau 14 posé sur l'échafaudage en vue de boucher l'espace qui pourrait exister entre le bord inférieur 15 d'une plinthe 13 et le bord du plateau 14. Ainsi, aucun objet ne peut se glisser entre le plateau 14 et une plinthe 13.The offset of the plane of symmetry ABFE of the tabs 3,4 with respect to the longitudinal plane of symmetry of the ABCDEFGH package makes it possible to offset the axis XX of a plinth 13 in the direction of the plate 14 placed on the scaffolding in order to plug the space that could exist between the lower edge 15 of a plinth 13 and the edge of the plate 14. Thus, no object can slip between the plate 14 and a plinth 13.

En outre, l'alternance des pattes 3,4, présentes au minimum au nombre de deux, permet de disposer d'une patte de fixation 3 (ou 4) au plus près de la partie basse de la plinthe 13 et d'une autre patte de fixation 4 (ou 3) au plus près de la partie haute de ladite plinthe 13.In addition, the alternation of tabs 3,4, present at least two in number, allows to have a bracket 3 (or 4) closer to the lower part of the baseboard 13 and another fixing lug 4 (or 3) closest to the upper part of said plinth 13.

L'embout 1 selon l'invention a l'énorme avantage d'empêcher de ce fait le flambement de la plinthe.The tip 1 according to the invention has the enormous advantage of preventing the buckling of the plinth.

La plinthe 13 correspondant à l'embout 1 décrit ci-dessus est formée d'un profilé métallique dont la section droite est représentée sur la Figure 5. Les parties latérales 16 de la plinthe 13 ont extérieurement une forme complémentaire des parties correspondantes de l'intérieur de l'élément de base 2 de l'embout 1.The plinth 13 corresponding to the nozzle 1 described above is formed of a metal section whose cross section is shown in Figure 5. The side portions 16 of the plinth 13 have a shape complementary to the corresponding parts of the outside. inside the base element 2 of the mouthpiece 1.

L'intérieur d'une section droite de l'élément de base 2 est typiquement un rectangle de 150 mm de haut et 30 mm de large, correspondant à une plinthe 13 dont la section présente globalement ces mêmes dimensions.The inside of a straight section of the base element 2 is typically a rectangle 150 mm high and 30 mm wide, corresponding to a plinth 13 whose section has generally these same dimensions.

Ces caractéristiques dimensionnelles respectives de l'embout 1 et de la plinthe 13 confèrent à l'embout 1 l'avantage d'être de préférence fixé de manière amovible à l'extrémité de la plinthe 13.These respective dimensional characteristics of the end piece 1 and the skirting 13 give the end piece 1 the advantage of being preferably removably attached to the end of the plinth 13.

Afin d'augmenter la rigidité de la plinthe 13, celle-ci présente une dépression longitudinale médiane 17 et des parties latérales 16 formant caisson. Typiquement, la partie médiane 17 de la plinthe 13 a une hauteur de 65 mm, et les caissons latéraux 16 ont une hauteur de l'ordre de 27 mm.In order to increase the rigidity of the plinth 13, it has a central longitudinal depression 17 and side portions 16 forming box. Typically, the median portion 17 of the plinth 13 has a height of 65 mm, and the side boxes 16 have a height of the order of 27 mm.

Les quatre pattes 3,4 utilisent au mieux la hauteur de 150 mm du boîtier 2 et ont donc chacune une hauteur de 30 mm.The four legs 3,4 best use the height of 150 mm of the housing 2 and therefore each have a height of 30 mm.

La profondeur de l'ouverture arrière du boîtier 2 pratiquée depuis la face ABCD est de 36 mm, c'est-à-dire que l'extrémité de la plinthe 13 est emboîtée sur une longueur de 36 mm dans l'embout 1 afin d'être fixée sur le montant 12 de l'échafaudage.The depth of the rear opening of the casing 2 made from the face ABCD is 36 mm, that is to say that the end of the baseboard 13 is nested over a length of 36 mm in the endpiece 1 in order to 'to be fixed on the amount 12 of the scaffolding.

L'embout 1, dans le mode de réalisation préféré de l'invention, est constitué d'une seule pièce moulée en PVC. L'épaisseur des parois du boîtier ABCDEFGH et des pattes 3,4 est alors de 4 mm ; les nervures 5 de renforcement ont une épaisseur de 5 mm.The tip 1, in the preferred embodiment of the invention consists of a single molded piece of PVC. The wall thickness of the ABCDEFGH housing and the lugs 3,4 is then 4 mm; the reinforcing ribs 5 have a thickness of 5 mm.

L'avantage d'un embout 1 en PVC par rapport à un embout 1 en acier est qu'il ne présente pas de bords coupants les risques de blessure au cours du montage de l'échafaudage sont donc diminués, et le niveau de sécurité du chantier est amélioré.The advantage of a PVC end piece 1 with respect to a steel end piece 1 is that it does not present sharp edges, the risk of injury during assembly of the scaffolding is therefore reduced, and the level of safety of the construction site is improved.

De plus, l'élasticité de ce matériau permet une accroche parfaite sur les tubes 12 d'échafaudage.In addition, the elasticity of this material allows a perfect grip on the scaffold tubes 12.

Le montage de l'embout 1 sur la plinthe 13 se résume à un simple emboîtement à l'extrémité de celle-ci.The mounting of the tip 1 on the skirting 13 is a simple interlocking at the end thereof.

En cas de détérioration d'un embout 1 ou d'une plinthe 13, l'utilisateur peut donc facilement effectuer la réparation en changeant seulement l'embout 1 ou la plinthe 13 selon le cas.In case of deterioration of a tip 1 or a baseboard 13, the user can easily perform the repair by changing only the tip 1 or the baseboard 13 as appropriate.

Comme il va de soi, l'invention ne se limite pas au seul mode d'exécution préférentiel décrit ci-dessus.It goes without saying that the invention is not limited to the single preferred embodiment described above.

Une description similaire s'applique notamment à une plinthe 13 ayant une section différente de celle représentée sur la Figure 5 dans la mesure où l'extrémité de la plinthe 13 et l'élément de base 2 de l'embout 1 sont conçus pour coopérer par emboîtement.A similar description applies in particular to a plinth 13 having a section different from that shown in FIG. 5 insofar as the end of the plinth 13 and the base element 2 of the end piece 1 are designed to cooperate by nesting.

Il va de soi également que le nombre, la forme et la disposition des pattes 3,4 spécifiés ci-dessus ne sont aussi donnés qu'à titre d'exemple. Par exemple, l'embout de plinthe selon l'invention pourrait comporter trois, voire quatre, paires de pattes inférieures 3 et supérieures 4.It goes without saying that the number, shape and arrangement of the tabs 3,4 specified above are also given as examples. For example, the skirting tip according to the invention could comprise three or even four pairs of lower legs 3 and upper 4.

L'invention embrasse donc toutes les variantes possibles de réalisation faisant l'objet des revendications ci-après.The invention therefore embraces all possible variants of embodiment subject of the claims below.
