Definitions
- the present invention relates to an articulated foot intended to be attached to scale uprights.
- Known articulated feet of the type comprising a connecting portion intended to be reported and immobilized in the amount of scale, a base forming a foot support foot on the surface on which is intended to rest the ladder, this base being movable relative to the connecting portion, and hinge means which rotatably connect the connecting portion and the base, to allow relative rotation of the base and the connecting portion in a single plane.
- the hinge means usually used are ball-and-socket means 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 on inclined ground, it has the disadvantage of leaving the user free to incline the ladder at high angles, including in a direction transversal to the scale. . Such a foot is difficult to use and presents a risk of misplacement, causing the sliding of the ladder, which can be dangerous for the user.
- the articulated feet commonly encountered are made of materials that do not ensure both the rigidity of the foot and a good grip of the foot on the surface on which the scale rests.
- the present invention is intended to overcome the aforementioned drawbacks by providing a new articulated foot ensuring both a good grip of the scale on the ground, a good positioning of the base relative to the ground, and a good rigidity d together, while being simple and inexpensive to manufacture.
- an articulated foot of the kind in question is essentially characterized in that the connecting part is made of rigid plastic material, in that the base is at least partly made of flexible plastic material and in that that the hinge means comprises a cylinder integrally formed with the connecting portion 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 articulated foot is made of only two materials, a rigid material with good mechanical strength and a flexible material for a good grip of the foot on the ground, while the base has a single degree of freedom compared at the party of link, which allows a secure positioning of the foot on the ground.
- a transverse inclination of the ladder is avoided.
- the joint is simple to perform since it has a minimum number of component parts.
- the base comprises a rigid plastic upper part and a lower part forming non-slip pad of flexible plastic material.
- the lower part of the base is reported by overmoulding on the upper part of said base.
- the base is made entirely of flexible plastic material.
- the manufacture of the articulated foot is therefore very simplified and the base can be adapted to connecting parts previously manufactured for several forms of ladder amounts.
- the base and the connecting portion comprise complementary means forming a stop to limit the relative rotation of the base of the connecting portion.
- the inclination of the ladder can not exceed a certain angle, which enhances the safety of the user.
- the connecting portion comprises at least one relief intended to cooperate with a complementary recess formed in the ladder amounts.
- the present invention also relates to a ladder comprising at least two uprights each provided with an articulated foot according to the above characteristics.
- the figure 1 represents the lower part of a scale 1 which has two longitudinal uprights 2, each equipped with an articulated foot 4 according to the present invention.
- Each articulated foot 4 has a connecting portion 10, a base 11 and articulation means 12.
- the connecting portion 10 is intended to be reported and immobilized in the corresponding amount 2.
- the base 11 forms a support piece of the foot 4 on the surface on which the scale 1 is intended to rest, this base being movable relative to the connecting portion 10.
- the articulation means 12 connect in rotation the connecting part 10 and the base 11.
- the connecting portion 10 has a head 15 and a body 16 both made of rigid plastic material such as for example polypropylene or polyamide. Of course, any other rigid plastic material in the cooled state is usable.
- the head 15 is of complementary shape to that of the cross section of the uprights 2 so that it can be nested therein.
- the body 16 has a flat rectangular upper face 17 from which the head 15 projects, and a lower face 18 facing the base 11.
- the lower face 18 has a crenellated profile, thus alternately defining 20, 21 and bumps 22, 23.
- the body 16 thus comprises two arms 25 and 26 which extend in the opposite direction and which each comprise a recess 20, 21 respectively, and a boss 22, 23 respectively.
- the recesses 20 and 21 are located near the ends of the two arms 25 and 26.
- the hinge means 10 comprise a cylinder 13 and a recess 37 described below.
- the cylinder 13 is integrally formed with the body 16 of the connecting portion 10, at the mid-length of this body, on the side of the lower face 18. It extends substantially parallel to the plane of the ladder. that is, transversely to the plane defined by the body 16 of the connecting portion 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 lower face of the body 16, at the junction between the two arms 25 and 26.
- the cylinder 13 being integral with the connecting portion 10, it is also made of a rigid material such as polypropylene.
- the arms 25 and 26 are a kind of rocker around the cylinder 13. This cylinder acts as a rotational axis for the connecting portion 10 which can rotate only in one degree of freedom.
- the base 11 takes the form of a block whose width is substantially equal to the width of the connecting portion 10 and whose upper face 30 is opposite and cooperates with the lower face 18 of the body 16 of this part of 10.
- the upper face 30 has two recesses 32, 33 and two bumps 34, 35 of shape complementary to that of the bumps and troughs of the body 16, the bumps and troughs of the base being located respectively opposite hollow and bumps of said body.
- a cylindrical recess 37 whose diameter is substantially equal to that of the diameter of the cylinder 13 of the hinge means 12.
- This recess 37 opens at the same time on the lateral faces and on the upper face 30 of the The base 11 thus has on the upper face an opening 38 whose dimensions are smaller than the diameter of the cylinder 13.
- the cylinder 13 is fitted into the recess 37 and the leg 19 projects out of the opening 38 so that the lower face 18 of the body 16 cooperates with the upper face 30 of the base 11.
- the upper face 30 of the base 11 is inclined with respect 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 ⁇ of about 70 °.
- the base 11 is in this first embodiment completely made of flexible plastic material. This material is chosen to obtain a good grip of the foot 4 on the surfaces on which the ladder is intended to rest. It may for example be terephthalate.
- the articulated foot is therefore made only with two materials, a rigid material with high mechanical characteristics and a flexible material having a good non-slip coefficient.
- the base 11 has a single degree of freedom relative to the connecting portion 10, which allows a safe positioning of the scale.
- 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 can not position the ladder at high angles of inclination that would be dangerous.
- the manufacturing process of the foot 4 consists first of all in obtaining, by molding or injection, the connecting portion 10 provided with the cylinder 13, then obtaining the base 11 by molding or injection.
- the cylinder 13 is then hot-fitted in the recess 37 of the base 11 so that after cooling, it is impossible to extract the cylinder 13 out of the recess.
- the connecting portion 10 is not simply nested, but positively immobilized by clipping.
- the head 15 has two elastic tabs 40 provided with reliefs 41 which cooperate with recesses 42 of complementary shape and formed in the uprights 2,3 of the scale 1.
- 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 portion 52 made of rigid plastic identical to that of the connecting portion 10 and a lower portion 53 which is overmolded below of the upper part 52 and which is made of non-slip flexible material and which is intended to come into contact with the ground.
- the other component parts of the foot 50 are similar to that of the foot 4 previously described.
- hinge means 60 do not take the form of a cylinder rotatably mounted in a recess but take the form of a web 61 which connects the upper portion 52 of the base 51 to the lower face 18 of the body 16 of the connecting part 10.
- the upper surface of the base is inclined to form an angle with the horizontal plane.
- 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.
- the bumps and reliefs of the base and the body of the connecting portion are adapted to allow maximum pivoting of the scale by an angle of 35 ° on either side of the vertical.
- the articulated foot according to the present invention has been associated with a ladder, it is understood that it can be used with any element that allows a user to reach a high point, such as a stepladder or a scaffold.

Description
La présente invention est relative à un pied articulé destiné à être rapporté sur des montants d'échelle.The present invention relates to an articulated foot intended to be attached to scale uprights.
On connaît des pieds articulés du type comprenant une partie de liaison destinée à être rapportée et immobilisée dans le montant d'échelle, une embase formant pied d'appui du pied sur la surface sur laquelle est destinée à reposer l'échelle, cette embase étant mobile par rapport à la partie de liaison, et des moyens d'articulation qui lient en rotation la partie de liaison et l'embase, pour permettre la rotation relative de l'embase et de la partie de liaison dans un seul plan.Known articulated feet of the type comprising a connecting portion intended to be reported and immobilized in the amount of scale, a base forming a foot support foot on the surface on which is intended to rest the ladder, this base being movable relative to the connecting portion, and hinge means which rotatably connect the connecting portion and the base, to allow relative rotation of the base and the connecting portion in a single plane.
Les moyens d'articulation habituellement utilisés sont des moyens à rotule qui permettent des mouvements de l'embase dans toutes les directions par rapport aux montants d'échelle. Même si ce type de pied permet d'adapter l'échelle sur des sols inclinés, il présente l'inconvénient de laisser libre l'utilisateur d'incliner l'échelle à de forts angles, y compris dans une direction transversale à l'échelle. Un tel pied est difficile d'utilisation et présente un risque de mauvais positionnement, entraînant le glissement de l'échelle, ce qui peut s'avérer dangereux pour l'utilisateur.The hinge means usually used are ball-and-socket means 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 on inclined ground, it has the disadvantage of leaving the user free to incline the ladder at high angles, including in a direction transversal to the scale. . Such a foot is difficult to use and presents a risk of misplacement, causing the sliding of the ladder, which can be dangerous for the user.
De plus, les pieds articulés couramment rencontrés sont réalisés avec des matières qui n'assurent pas à la fois la rigidité du pied et une bonne accroche de ce pied sur la surface sur laquelle repose l'échelle.In addition, the articulated feet commonly encountered are made of materials that do not ensure both the rigidity of the foot and a good grip of the foot on the surface on which the scale rests.
La présente invention a notamment pour but de remédier aux inconvénients précités en fournissant un nouveau pied articulé assurant tout à la fois une bonne accroche de l'échelle au sol, un bon positionnement de l'embase par rapport au sol, et une bonne rigidité d'ensemble, tout en étant d'une fabrication simple et peu coûteuse.The present invention is intended to overcome the aforementioned drawbacks by providing a new articulated foot ensuring both a good grip of the scale on the ground, a good positioning of the base relative to the ground, and a good rigidity d together, while being simple and inexpensive to manufacture.
A cet effet, selon l'invention, un pied articulé du genre en question est essentiellement caractérisé en ce que la partie de liaison est en matière plastique rigide, en ce que l'embase est au moins en partie en matière plastique souple et en ce que les moyens d'articulation comprennent un cylindre venu de matière avec la partie de liaison et un logement ménagé dans l'embase, le cylindre s'étendant sensiblement parallèlement au plan de l'échelle et étant emboîté dans le logement.For this purpose, 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 material, in that the base is at least partly made of flexible plastic material and in that that the hinge means comprises a cylinder integrally formed with the connecting portion and a housing formed in the base, the cylinder extending substantially parallel to the plane of the scale and being fitted into the housing.
Grâce à ces dispositions, le pied articulé est réalisé en seulement deux matières, une matière rigide offrant de bonnes résistances mécaniques et une matière souple permettant une bonne accroche du pied sur le sol, tandis que l'embase possède un seul degré de liberté par rapport à la partie de liaison, ce qui permet un positionnement sûr du pied au sol. Une inclinaison transversale de l'échelle est en outre ainsi évitée. De plus, l'articulation est simple à réaliser puisqu'elle compte un nombre minimum de pièces constitutives.Thanks to these provisions, the articulated foot is made of only two materials, a rigid material with good mechanical strength and a flexible material for a good grip of the foot on the ground, while the base has a single degree of freedom compared at the party of link, which allows a secure positioning of the foot on the ground. In addition, a transverse inclination of the ladder is avoided. In addition, the joint is simple to perform since it has a minimum number of component parts.
De manière préférée, l'embase comprend une partie supérieure en matière plastique rigide et une partie inférieure formant patin anti-dérapant en matière plastique souple.Preferably, the base comprises a rigid plastic upper part and a lower part forming non-slip pad of flexible plastic material.
De manière encore préférée, la partie inférieure de l'embase est rapportée par surmoulage sur la partie supérieure de ladite embase.More preferably, the lower part of the base is reported by overmoulding on the upper part of said base.
Encore avantageusement, l'embase est réalisée en totalité en matière plastique souple. La fabrication du pied articulé est donc très simplifiée et l'embase peut être adaptée sur des parties de liaison préalablement fabriquées pour plusieurs formes de montants d'échelle.Still advantageously, the base is made entirely of flexible plastic material. The manufacture of the articulated foot is therefore very simplified and the base can be adapted to connecting parts previously manufactured for several forms of ladder amounts.
De manière avantageuse, l'embase et la partie de liaison comprennent des moyens complémentaires formant butée pour limiter la rotation relative de l'embase de la partie de liaison. L'inclinaison de l'échelle ne peut ainsi pas dépasser un certain angle, ce qui renforce la sécurité de l'utilisateur.Advantageously, the base and the connecting portion comprise complementary means forming a stop to limit the relative rotation of the base of the connecting portion. The inclination of the ladder can not exceed a certain angle, which enhances the safety of the user.
Pour faciliter la mise en place du pied dans un montant d'échelle, la partie de liaison comprend au moins un relief destiné à venir coopérer avec un évidement complémentaire ménagé dans les montants d'échelle.To facilitate the placement of the foot in a ladder, the connecting portion comprises at least one relief intended to cooperate with a complementary recess formed in the ladder amounts.
La présente invention a également pour objet une échelle comprenant au moins deux montants chacun muni d'un pied articulé selon les caractéristiques précitées.The present invention also relates to a ladder comprising at least two uprights each provided with an articulated foot according to the above characteristics.
La présente invention a encore pour objet un procédé de fabrication d'un pied articulé qui comprend les étapes consistant à
- réaliser ensemble à chaud la partie de liaison et le cylindre d'articulation en matière plastique rigide ;
- réaliser à chaud l'embase en matière plastique souple ; et
- emboîter le cylindre dans l'embase avant le refroidissement de l'embase.
- performing together hot the connecting portion and the hinge cylinder of rigid plastic material;
- hot make the base of flexible plastic material; and
- fit the cylinder in the base before cooling the base.

L'embase 11 forme une pièce d'appui du pied 4 sur la surface sur laquelle l'échelle 1 est destinée à reposer, cette embase étant mobile par rapport à la partie de liaison 10. Les moyens d'articulation 12 lient en rotation la partie de liaison 10 et l'embase 11.The
Comme cela est plus particulièrement représenté aux
Comme le montre plus particulièrement la
Le cylindre 13 étant venu de matière avec la partie de liaison 10, il est également réalisé en une matière partie rigide telle que du polypropylène. Les bras 25 et 26 constituent en quelque sorte un balancier autour du cylindre 13. Ce cylindre joue le rôle d'axe de rotation pour la partie de liaison 10 qui ne peut donc pivoter que selon un seul degré de liberté.The
L'embase 11 prend la forme d'un bloc dont la largeur est sensiblement égale à la largeur de la partie de liaison 10 et dont la face supérieure 30 est en regard et vient coopérer avec la face inférieure 18 du corps 16 de cette partie de liaison 10. A cet effet, la face supérieure 30 possède deux creux 32, 33 et deux bosses 34, 35 de forme complémentaires de celle des bosses et creux du corps 16, les bosses et creux de l'embase étant respectivement situés en regard des creux et bosses dudit corps.The
Dans l'embase 11 est ménagé un évidement cylindrique 37 dont le diamètre est sensiblement égal à celui du diamètre du cylindre 13 des moyens d'articulation 12. Cet évidement 37 débouche à la fois sur les faces latérales et sur la face supérieure 30 de l'embase 11. L'embase 11 possède ainsi en face supérieure une ouverture 38 dont les dimensions sont inférieures au diamètre du cylindre 13.In the
Le cylindre 13 est emboîté dans l'évidement 37 et la jambe 19 fait saillie hors de l'ouverture 38 pour que la face inférieure 18 du corps 16 coopère avec la face supérieure 30 de l'embase 11.The
Par ailleurs, la face supérieure 30 de l'embase 11 est inclinée par rapport à la face inférieure 31 de sorte que même dans la position de repos (
Dans la position active (
L'embase 11 est dans ce premier mode de réalisation totalement réalisée en matière plastique souple. Cette matière est choisie pour obtenir une bonne accroche du pied 4 sur les surfaces sur lesquelles l'échelle est destinée à reposer. Il peut par exemple s'agir de téréphtalate.The
Le pied articulé est donc réalisé uniquement avec deux matières, une matière rigide à caractéristiques mécaniques élevées et une matière souple ayant un bon coefficient anti-dérapant. De plus, l'embase11 possède un seul degré de liberté par rapport à la partie de liaison 10, ce qui permet un positionnement sûr de l'échelle. En outre, même en position de repos, le pied articulé selon la présente invention donne un certain angle d'inclinaison à l'échelle par rapport à la verticale. La variation d'angle autour de cette position de repos est limitée de sorte que l'utilisateur ne peut positionner l'échelle à de forts angles d'inclinaison qui seraient dangereux.The articulated foot is therefore made only with two materials, a rigid material with high mechanical characteristics and a flexible material having a good non-slip coefficient. In addition, the
Le procédé de fabrication du pied 4 consiste tout d'abord à obtenir par moulage ou injection la partie de liaison 10 munie du cylindre 13, puis à obtenir par moulage ou injection l'embase 11. Le cylindre 13 est ensuite emboîté à chaud dans l'évidement 37 de l'embase 11 de sorte qu'après refroidissement, il est impossible d'extraire le cylindre 13 hors de l'évidement.The manufacturing process of the

A la
Dans les modes de réalisation précédents, la surface supérieure de l'embase est inclinée pour former un angle avec le plan horizontal. Dans d'autres modes de réalisation, et sans sortir du cadre de la présente invention, cette face supérieure peut être horizontale (c'est-à-dire parallèle à la face inférieure de cette embase) de sorte que dans sa position de repos, l'échelle est verticale. Les bosses et reliefs de l'embase et du corps de la partie de liaison sont adaptés pour permettre un pivotement maximum de l'échelle d'un angle de 35° de part et d'autre de la verticale.In the previous embodiments, the upper surface of the base is inclined to form an angle with the horizontal plane. In other embodiments, and without departing from the scope of the present invention, 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. The bumps and reliefs of the base and the body of the connecting portion are adapted to allow maximum pivoting of the scale by an angle of 35 ° on either side of the vertical.
Le pied articulé selon la présente invention a été associé à une échelle, on comprend qu'il peut être utilisé avec tout élément qui permet à un utilisateur d'atteindre un point haut, tel qu'un escabeau ou encore un échafaudage.The articulated foot according to the present invention has been associated with a ladder, it is understood that it can be used with any element that allows a user to reach a high point, such as a stepladder or a scaffold.
Bien entendu, le pied articulé selon la présente invention ne se limite pas aux formes de réalisation préférentielles décrites ci-dessus à titre d'exemple, il embrasse au contraire toutes les variantes de réalisation dans le cadre des revendications ci-après.Of course, the articulated foot according to the present invention is not limited to the preferred embodiments described above by way of example, it embraces on the contrary all embodiments within the scope of the claims below.
