On conna^'t des pieds articules du type comprenant une partie de liaison destinee 3 etre rapportee et immobilisee dans le montant d'echelle, une embase formant pied d'appui du pied sur la surface sur laquelle est destinee a reposer l'echelle, cette embase etant mobile par rapport 3 la partie de liaison, There are known articulated feet of the type comprising a connecting part intended to be attached and immobilized in the ladder upright, a base forming a foot supporting the foot on the surface on which is intended to rest the ladder, this base being movable relative to the connecting part 3,
et des moyens d'articulation qui liens en rotation la partie de liaison et l'embase. and articulation means which rotate the connection part and the base.
Les moyens d'articulation habituellement utilises vent des moyens 3 rotule qui permettent des mouvements de l'embase dans toutes les directions par rapport aux montants d'echelle. Meme si ce type de pied permet d'adapter l'echelle sur des sols inclines, il presente ['inconvenient de laisser libre l'utilisateur d'incliner l'echelle 3 de forts angles, y compris dans une direction transversale 3 I'echelle. Un tel pied est difficile d'utilisation et presente un risque de mauvais positionnement, entranant le glissement de l'echelle, ce qui The articulation means usually used are ball means 3 which allow movements of the base in all directions relative to the ladder uprights. Even if this type of foot makes it possible to adapt the ladder to inclined floors, it has the disadvantage of leaving the user free to tilt the ladder 3 at strong angles, including in a transverse direction at the ladder. . Such a foot is difficult to use and presents a risk of incorrect positioning, causing the sliding of the ladder, which
peut s'averer dangereux pour l'utilisateur. may be dangerous for the user.
De plus, les pieds articules couramment rencontres vent realises avec des matieres qui n'assurent pas 3 la fois la rigidite du pied et une bonne In addition, the articulated feet commonly encountered wind made with materials that do not provide both the stiffness of the foot and good
accroche de ce pied sur la surface sur laquelle repose l'echelle. hang this foot on the surface on which the ladder rests.
La presente invention a notamment pour but de remedier aux inconvenients precites en fournissant un nouveau pied articule assurant tout 3 la fois une bonne accroche de l'echelle au sol, un bon positionnement de l'embase par rapport au sol, et une bonne rigidite d'ensemble, tout en etant The object of the present invention is in particular to remedy the aforementioned drawbacks by providing a new articulated foot ensuring all 3 both good attachment of the ladder to the ground, good positioning of the base relative to the ground, and good rigidity d together while being
d'une fabrication simple et peu couteuse. simple and inexpensive to manufacture.
A cet effet, selon ['invention, un pied articule du genre en question est essentiellement caracterise en ce que la partie de liaison est en matiere plastique rigide, en ce que l'embase est au moins en partie en matiere plastique souple et en ce que les moyens d'articulation permettent la rotation To this end, according to the invention, an articulated foot of the kind in question is essentially characterized in that the connecting part is made of rigid plastic, in that the base is at least partly made of flexible plastic and in that that the means of articulation allow rotation
relative de l'embase et de la partie de liaison dans un seul plan. relative of the base and the connecting part in a single plane.
Grace 3 ces dispositions, le pied articule est realise en seulement deux matieres, une matiere rigide offrant de bonnes resistances mecaniques et une matiere souple permettant une bonne accroche du pied sur le sol, tandis que l'embase possede un seul degre de liberte par rapport 3 la partie de liaison, ce qui permet un positionnement sur du pied au sol. Une inclinaison Thanks to these provisions, the articulated foot is made of only two materials, a rigid material offering good mechanical resistance and a flexible material allowing good grip of the foot on the ground, while the base has only one degree of freedom with respect to 3 the connecting part, which allows positioning on the foot on the ground. A tilt
transversale de l'echelle est en outre ainsi evitee. in addition, the transverse scale is avoided.
Avantageusement, les moyens d'articulation comprennent un cylindre venu de matiere avec la partie de liaison et un logement menage dans I'embase, le cylindre s'etendant sensiblement parallelement au plan de liechelle et etant embo^'te dans le logement. L'articulation est ainsi simple a Advantageously, the articulation means comprise a cylinder made of material with the connection part and a housing formed in the base, the cylinder extending substantially parallel to the plane of the scale and being fitted into the housing. The articulation is thus simple to
realiser puisqu'elle compte un nombre minimum de pieces constitutives. realize since it has a minimum number of constituent parts.
De maniere preferee, I'embase comprend une partie superieure en matiere plastique rigide et une partie inferieure formant patin anti-derapant en Preferably, the base includes an upper part made of rigid plastic and a lower part forming an anti-slip pad in
matiere plastique souple.flexible plastic.
De maniere encore preferee, la partie inferieure de l'embase est Even more preferably, the lower part of the base is
rapportee par surmoulage sur la partie superieure de ladite embase. attached by overmolding on the upper part of said base.
Encore avantageusement, I'embase est realisee en totalite en matiere plastique souple. La fabrication du pied articule est done tres simplifiee et l'embase peut etre adaptee sur des parties de liaison prealablement Still advantageously, the base is made entirely of flexible plastic. The manufacture of the articulated foot is therefore very simplified and the base can be adapted on connecting parts beforehand
fabriquees pour plusieurs formes de montants d'echelle. manufactured for several forms of ladder uprights.
L'embase comprend avantageusement une partie superieure en matiere plastique rigide et les moyens d'articulation comprennent un voile s'etendant dans un plan sensiblement parallele au plan de 1'echelle. L'embase The base advantageously comprises an upper part made of rigid plastic and the articulation means comprise a veil extending in a plane substantially parallel to the plane of the scale. The base
et la partie de liaison peuvent ainsi etre fabriquees ensemble. and the connecting part can thus be manufactured together.
De maniere avantageuse, I'embase et la partie de liaison comprennent des moyens complementaires formant butee pour limiter la rotation relative de l'embase de la partie de liaison. L'inclinaison de l'echelle ne peut ainsi pas depasser un certain angle, ce qui renforce la securite de l'utilisateur. Pour faciliter la mise en place du pied dans un montant d'echelle, la partie de liaison comprend au moins un relief destine 3 venir cooperer avec un Advantageously, the base and the connecting part comprise complementary means forming a stop to limit the relative rotation of the base of the connecting part. The inclination of the ladder cannot thus exceed a certain angle, which reinforces the safety of the user. To facilitate the installation of the foot in a ladder upright, the connecting part comprises at least one relief intended to come and cooperate with a
evidement complementaire menage dans les montants d'echelle. additional recess in the uprights.
La presente invention a egalement pour objet une echelle comprenant au moins deux montants chacun muni d'un pied articule selon les The present invention also relates to a ladder comprising at least two uprights each provided with an articulated foot according to
caracteristiques precitees.above-mentioned characteristics.
La presente invention a encore pour objet un procede de fabrication d'un pied articule qui comprend les etapes consistent a - realiser ensemble a chaud la partie de liaison et le cylindre d'articulation en matiere plastique rigide; - realiser a chaud l'embase en matiere plastique souple; et - emboter le cylindre dans l'embase avant le refroidissement de l'embase. D'autres caracteristiques et avantages de ['invention appara^'tront The present invention also relates to a method of manufacturing an articulated foot which comprises the steps consist of - making together hot the connecting part and the articulation cylinder in rigid plastic; - heat the base in flexible plastic; and - embed the cylinder in the base before the base cools down. Other features and advantages of the invention will become apparent

La figure 1 represente la partie basse une echelle 1 qui possede deux montants longitudinaux 2, chacun equipe d'un pied articule 4 selon la Figure 1 shows the lower part a ladder 1 which has two longitudinal uprights 2, each fitted with an articulated foot 4 according to the
presente invention.present invention.
Chaque pied articule 4 possede une partie de liaison 10, une Each articulated leg 4 has a connecting part 10, a
embase 11 et des moyens d'articulation 12. base 11 and articulation means 12.
La partie de liaison 10 est destinee a etre rapportee et immobilisee The connecting part 10 is intended to be attached and immobilized
dans le montant correspondent 2.in the amount correspond 2.
L'embase 11 forme une piece d'appui du pied 4 sur la surface sur laquelle l'echelle 1 est destinee a reposer, cette embase etant mobile par rapport 3 la partie de liaison 10. Les moyens d'articulation 12 liens en rotation la The base 11 forms a support piece for the foot 4 on the surface on which the ladder 1 is intended to rest, this base being movable relative to the connecting part 10. The articulation means 12 links in rotation the
partie de liaison 10 et ltembase 11. connecting part 10 and base 11.
Comme cela est plus particulierement represente aux figures 2 et 3, la partie de liaison 10 possede une tete 15 et un corps 16 realises tous les deux en matiere plastique rigide tel que par exemple du polypropylene ou bien encore du polyamide. Bien entendu, tout autre matiere plastique rigide a l'etat refroidi est utilisable. La tete 15 est de forme complementaire de celle de la section transversale des montants 2 afin qutelle puisse y etre embo'^tee. Le corps 16 possede une face superieure 17 rectangulaire de forme plate a partir de laquelle fait saillie la tete 15, et une face inferieure 18 tournee vers l'embase 11. La face inferieure 18 possede un profil en forme de creneaux, definissant ainsi alternativement des creux 20, 21 et des bosses 22, 23. Le corps 16 comprend ainsi deux bras 25 et 26 qui s'etendent en direction opposee et qui comportent chacun un creux 20, 21 respectivement, et une bosse 22, 23 respectivement. Les creux 20 et 21 vent situes au voisinage des extremites des As is more particularly shown in Figures 2 and 3, the connecting portion 10 has a head 15 and a body 16 both made of rigid plastic such as for example polypropylene or even polyamide. Of course, any other rigid plastic material in the cooled state can be used. The head 15 is of complementary shape to that of the cross section of the uprights 2 so that it can be fitted therein. The body 16 has a rectangular upper face 17 of flat shape from which the head 15 projects, and a lower face 18 turned towards the base 11. The lower face 18 has a profile in the form of notches, thus alternately defining recesses 20, 21 and bumps 22, 23. The body 16 thus comprises two arms 25 and 26 which extend in opposite directions and which each comprise a recess 20, 21 respectively, and a bump 22, 23 respectively. Troughs 20 and 21 are located near the ends of the
S deux bras 25 et 26.S two arms 25 and 26.
Comme le montre plus particulierement la figure 3, les moyens As shown more particularly in FIG. 3, the means
d'articulation 10 comprennent un cylindre 13 et un evidement 37 decrit ci- articulation 10 comprise a cylinder 13 and a recess 37 described above
apres. Le cylindre 13 est venu de matiere avec le corps 16 de la partie de liaison 10, a mi-longueur de ce corps, du cote de la face inferieure 18.11 s'etend sensiblement parallelement au plan de l'echelle c'est-a- dire, transversalement au plan defini par le corps 16 de la partie de liaison 10. La longueur du cylindre est sensiblement egale ou legerement inferieure a la largeur du corps 16. Le cylindre 13 est situe a ltextremite d'une jambe 19 qui s'etend a partir de la face after. The cylinder 13 came in material with the body 16 of the connecting part 10, halfway along this body, on the side of the lower face 18.11 extends substantially parallel to the plane of the scale that is to say say, transverse to the plane defined by the body 16 of the connecting part 10. The length of the cylinder is substantially equal to or slightly less than the width of the body 16. The cylinder 13 is located at the end of a leg 19 which extends from the front
inferieure du corps 16, au niveau de la jonction entre les deux bras 25 et 26. lower body 16, at the junction between the two arms 25 and 26.
Le cylindre 13 etant venu de matiere avec la partie de liaison 10, il The cylinder 13 having come in material with the connecting part 10, it
est egalement realise en une matiere partie rigide telle que du polypropylene. is also made of a rigid part material such as polypropylene.
Les bras 25 et 26 constituent en quelque sorte un balancier autour du cylindre 13. Ce cylindre joue le role d'axe de rotation pour la partie de liaison 10 qui ne The arms 25 and 26 constitute a sort of pendulum around the cylinder 13. This cylinder acts as an axis of rotation for the connecting part 10 which does not
peut done pivoter que selon un seul degre de liberte. can therefore pivot only according to a single degree of freedom.
L'embase 11 prend la forme d'un bloc dont la largeur est sensiblement egale a la largeur de la partie de liaison 10 et dont la face superieure 30 est en regard et vient cooperer avec la face inferieure 18 du corps 16 de cette partie de liaison 10. A cet effet, la face superieure 30 possede deux creux 32, 33 et deux bosses 34, 35 de forme complementaires de celle des bosses et creux du corps 16, les bosses et creux de l'embase The base 11 takes the form of a block whose width is substantially equal to the width of the connecting part 10 and whose upper face 30 is opposite and comes to cooperate with the lower face 18 of the body 16 of this part of connection 10. To this end, the upper face 30 has two recesses 32, 33 and two bumps 34, 35 of shape complementary to that of the bumps and hollows of the body 16, the bumps and hollows of the base
etant respectivement situes en regard des creux et bosses audit corps. being respectively located opposite the hollows and bumps in said body.
Dans l'embase 11 est menage un evidement cylindrique 37 dont le diametre est sensiblement egal 3 celui du diametre du cylindre 13 des moyens d'articulation 12. Cet evidement 37 debouche a la fois sur les faces laterales et sur la face superieure 30 de l'embase 11. L'embase 11 possede ainsi en face superieure une ouverture 38 dont les dimensions vent inferieures au diametre In the base 11 is formed a cylindrical recess 37 whose diameter is substantially equal to 3 that of the diameter of the cylinder 13 of the articulation means 12. This recess 37 opens both on the lateral faces and on the upper face 30 of the 'base 11. The base 11 thus has on the upper face an opening 38 whose wind dimensions less than the diameter
du cylindre 13.of cylinder 13.
Le cylindre 13 est embo^'te dans lievidement 37 et la jambe 19 fait saillie hors de l'ouverture 38 pour que la face inferieure 18 du corps 16 coopere The cylinder 13 is fitted in place 37 and the leg 19 projects from the opening 38 so that the lower face 18 of the body 16 cooperates
avec la face superieure 30 de l'embase 11. with the upper face 30 of the base 11.
Par ailleurs, la face superieure 30 de l'embase 11 est inclinee par rapport a la face inferieure 31 de sorte que meme dans la position de repos (figure 2) le corps 16 forme un certain angle avec la verticale. Cet angle est de preference de l'ordre de 30 de sorte que l'echelle est inclinee par rapport au sol d'un angle a d'environ 70 . Dans la position active (figure 3), la moitie de la longueur de la face inferieure 18 du corps 16 vient en butee sur la moitie correspondante de la face superieure 30 de l'embase 11, par basculement autour du cylindre 13. Les reliefs et creux de ces faces cooperent pour bloquer de facon sure l'echelle en position inclinee. L'echelle peut ainsi pivoter d'un angle maximum Furthermore, the upper face 30 of the base 11 is inclined relative to the lower face 31 so that even in the rest position (Figure 2) the body 16 forms a certain angle with the vertical. This angle is preferably of the order of 30 so that the scale is inclined relative to the ground by an angle α of approximately 70. In the active position (FIG. 3), half the length of the lower face 18 of the body 16 abuts on the corresponding half of the upper face 30 of the base 11, by tilting around the cylinder 13. The reliefs and the hollow of these faces cooperate to secure the ladder in an inclined position. The ladder can thus pivot by a maximum angle
predetermine, par exemple de l'ordre de 5 autour de sa position de repos. predetermines, for example around 5 around its rest position.
L'embase 11 est dans ce premier mode de realisation totalement realisee en matiere plastique souple. Cette matiere est choisie pour obtenir une bonne accroche du pied 4 sur les surfaces sur lesquelles l'echelle est destinee The base 11 is in this first embodiment completely made of flexible plastic. This material is chosen to obtain a good grip of the foot 4 on the surfaces on which the ladder is intended
a reposer. II peut par exemple s'agir de terephtalate. to rest. It may for example be terephthalate.
Le pied articule est done realise uniquement avec deux matieres, une matiere rigide a caracteristiques mecaniques elevees et une matiere souple ayant un bon coefficient anti-derapant. De plus, I'embase11 possede un seul degre de liberte par rapport a la partie de liaison 10, ce qui permet un positionnement sur de l'echelle. En outre, meme en position de repos, le pied articule selon la presente invention donne un certain angle d'inclinaison a l'echelle par rapport a la verticale. La variation d'angle autour de cette position de repos est limitee de sorte que l'utilisateur ne peut positionner l'echelle a de The articulated foot is therefore made only with two materials, a rigid material with high mechanical characteristics and a flexible material having a good anti-slip coefficient. In addition, the base 11 has only one degree of freedom with respect to the connecting part 10, which allows positioning on the ladder. In addition, even in the rest position, the articulated foot according to the present invention gives a certain angle of inclination to the scale relative to the vertical. The angle variation around this rest position is limited so that the user cannot position the ladder at
forts angles d'inclinaison qui seraient dangereux. large angles of inclination which would be dangerous.
Le procede de fabrication du pied 4 consiste tout d'abord a obtenir par moulage ou injection la partie de liaison 10 munie du cylindre 13, puis a obtenir par moulage ou injection l'embase 1 1. Le cylindre 13 est ensuite embo^'te a chaud dans l'evidement 37 de liembase 11 de sorte qu'apres The manufacturing process of the leg 4 consists firstly in obtaining by molding or injection the connecting part 10 provided with the cylinder 13, then in obtaining by molding or injection the base 1 1. The cylinder 13 is then fitted hot in the recess 37 of the base 11 so that after
refroidissement, il est impossible d'extraire le cylindre 13 hors de l'evidement. cooling, it is impossible to extract the cylinder 13 out of the recess.
Dans la variante de realisation representee a la figure 4, la partie de liaison 10 n'est pas simplement embo^'tee, mais immobilisee positivement par clipsage. A cet effet, la tete 15 possede deux pastes elastiques 40 munies de reliefs 41 qui viennent cooperer avec des evidements 42 de forme In the alternative embodiment represented in FIG. 4, the connecting part 10 is not simply fitted, but positively immobilized by clipping. To this end, the head 15 has two elastic pastes 40 provided with reliefs 41 which come to cooperate with recesses 42 of shape
complementaire et menages dans les montants 2,3 de l'echelle 1. additional and household in the amounts 2,3 of the scale 1.
Dans le second mode de realisation represente a la figure 5, le pied d'articulation 50 differe du premier de realisation uniquement par le fait que I'embase 51 est realisee en deux matieres differentes. Cette embase possede alors une partie superieure 52 realisee en matiere plastique rigide identique a In the second embodiment shown in Figure 5, the hinge foot 50 differs from the first embodiment only in that the base 51 is made of two different materials. This base then has an upper part 52 made of rigid plastic identical to
celle de la partie de liaison lO et une partie inferieure 53 qui est surmoulee au- that of the connecting part 10 and a lower part 53 which is overmolded
dessous de la partie superieure 52 et qui est realisee en matiere souple anti- below the upper part 52 and which is made of flexible anti-
derapante et qui est destinee a venir en contact avec le sol. Les autres parties constitutives du pied 50 vent similaires a celle du slip and which is intended to come into contact with the ground. The other constituent parts of the foot 50 are similar to that of the
pied 4 precede mm ent decrit.foot 4 precedes mm ent described.
A la figure 6 est represente un troisieme mode de realisation qui differe du second mode de realisation precedent uniquement par les moyens d'articulation. Ces moyens d'articulation 60 ne prennent plus la forme d'un cylindre monte rotatif dans un evidement mais prennent la forme d'un voile 61 qui relic la partie superieure 52 de l'embase 51 a la face inferieure 18 du corps In Figure 6 is shown a third embodiment which differs from the second embodiment above only by the articulation means. These articulation means 60 no longer take the form of a cylinder mounted to rotate in a recess but take the form of a web 61 which connects the upper part 52 of the base 51 to the lower face 18 of the body
16 de la partie de liaison 10.16 of the connecting part 10.
Dans les modes de realisation precedents, la surface superieure de In the previous embodiments, the upper surface of
I'embase est inclinee pour former un angle avec le plan horizontal. Dans The base is inclined to form an angle with the horizontal plane. In
d'autres modes de realisation, et sans sortir du cadre de la presente invention, other embodiments, and without departing from the scope of the present invention,
cette face superieure peut etre horizontale (c'est-a-dire parallele a la face inferieure de cette embase) de sorte que dans sa position de repos, I'echelle est verticale. Les bosses et reliefs de l'embase et du corps de la partie de liaison vent adaptes pour permettre un pivotement maximum de l'echelle d'un this upper face may be horizontal (that is to say parallel to the lower face of this base) so that in its rest position, the scale is vertical.
