Abstract

The present invention relates to telescopic platform-support mast transverse stability device including sectional girders sliding between one another by means of rollers, the device including a runner (1) made of synthetic material exhibiting a threaded end (2) screwing into the threaded recess (3) formed in the end of the rod (4) for the support of rollers (5) bearing on the wings (flanges) (6) of the section (7) of one of the girders (8), the runner (1) after fitting the girders (8) being adjusted to bear on the web (9) of the said sections (7).

Description

La présente invention concerne un dispositif pour la stabilité transversale de mâts télescopiques supports de plateforme élévatrice.The present invention relates to a device for the transverse stability of telescopic masts lifting platform supports.

On connait les mâts télescopiques supports de plateforme élévatrice, - tel que décrit par le brevet FR 2 324 567 ou US 4 015 686 comportant des montants parallèles en forme de cage coulissant entre eux au moyen de galets fixés alternativement en partie basse et haute desdits montants afin de faciliter leur coulissement, le jeu latéral des montants est compensé par leur dévers lors de leur déploiement qui provoque l'appui des galets sur les ailes des cages. Toutefois ce mode de réalisation présente un inconvénient au niveau de la stabilité transversale ou dévers transversal qui n'est pas assuré de manière rigoureuse compte tenu qu'il est nécessaire pour un bon coulissement des montants entre eux de laisser un certain jeu entre les âmes reliant les ailes parallèles sur lesquelles prennent appui les galets et les faces latérales des galets.We know the telescopic masts lifting platform supports, - as described by patent FR 2 324 567 or US 4 015 686 comprising parallel uprights in the form of a cage sliding between them by means of rollers fixed alternately in the lower and upper part of said uprights in order to facilitate their sliding, the lateral play of the uprights is compensated by their cant when deployed which causes the rollers to rest on the wings of the cages. However, this embodiment has a drawback in terms of transverse stability or transverse cant which is not rigorously ensured given that it is necessary for good sliding of the uprights between them to leave a certain play between the connecting souls the parallel wings on which the rollers bear and the lateral faces of the rollers.

Afin de pallier à cet inconvénient on connaît par le brevet FR 89 07991 au nom du demandeur, le réglage ou rattrapage dudit jeu pour obtenir la stabilité transversale et éviter le dévers, l'utilisation des extrémités des axes supports de galets pour prendre appui sur les âmes des montants leur faisant face, ce réglage est obtenu lors du montage au moyen du filetage de l'axe et du contre-écrou de blocage. Ce mode de rattrapage et réglage est relativement laborieux car il nécessite des faces de montants parfaitement planes et parallèles ce qui rend la réalisation et l'assemblage desdits montants trés délicat.In order to overcome this drawback, the French patent FR 89 07991 discloses in the name of the applicant the adjustment or take-up of said clearance to obtain transverse stability and avoid cant, the use of the ends of the roller support axes to bear on the cores of the uprights facing them, this adjustment is obtained during assembly by means of the thread of the axis and the locking lock nut. This mode of catching up and adjustment is relatively laborious because it requires perfectly flat and parallel upright faces, which makes the production and assembly of said uprights very delicate.

L'invention a pour but de pallier aux inconvénients précédemment exposés.The invention aims to overcome the drawbacks described above.

L'invention a pour objet un dispositif de stabilité transversale des mâts télescopiques supports de plateforme comportant des montants profilés coulissant entre eux au moyen de galets, le dispositif étant caractérisé en ce qu'il consiste à visser en l'extrémité des axes des galets dans un filetage prévu à cet effet l'extrémité filetée d'un patin en matière généralement synthétique du type "Téflon" ou autres matériaux spéciaux, puis à régler au montage par dévissage lesdits patins jusqu'à ce qu'ils prennent appui sur l'âme des montants profilés, l'immobilisation des patins étant obtenue naturellement par les filetages réalisés de manière à forcer.The subject of the invention is a device for transverse stability of the telescopic masts platform supports comprising profiled uprights sliding between them by means of rollers, the device being characterized in that it consists in screwing at the end of the axes of the rollers in a thread provided for this purpose the threaded end of a pad of generally synthetic material of the "Teflon" type or other special materials, then to be adjusted during assembly by unscrewing said pads until they bear on the core profiled uprights, the immobilization of the pads being obtained naturally by the threads made so as to force.

D'autres caractéristiques et avantages de l'invention ressortiront plus clairement de la description qui va suivre faite en regard du dessin joint d'un élément du montant parallèle étant entendu qu'un montant est constitué de deux éléments parallèles et symétriques, ledit dessin étant donné à titre d'exemple non limitatif. Other characteristics and advantages of the invention will emerge more clearly from the description which follows, given with regard to the attached drawing of an element of the parallel upright, it being understood that an upright is made up of two parallel and symmetrical elements, said drawing being given by way of nonlimiting example.

Tel que représenté le dispositif comporte un patin 1 en matière synthétique tel que "Téflon" ou autres matériaux spéciaux présentant une extrémité 2 filetée se vissant dans l'évidement fileté 3 aménagé en l'extrémité de l'axe 4 supports de galets 5 s'appuyant sur les ailes 6 du profil 7 d'un des montants 8, le patin 1 aprés montage des montants 8 entre eux est ajusté en appui sur l'âme 9 desdits profils 7, le réglagle étant réalisé au moyen d'une clé par exemple s'enfourchant sur les côtés 10 en quatre ou six pans du patin 1, l'immobilisation au réglage choisi étant obtenue naturellement par les filetages entre eux qui sont réalisés de manière à forcer. As shown, the device comprises a pad 1 made of synthetic material such as "Teflon" or other special materials having a threaded end 2 screwed into the threaded recess 3 arranged at the end of the axis 4 roller supports 5 s' pressing on the wings 6 of the profile 7 of one of the uprights 8, the shoe 1 after mounting the uprights 8 between them is adjusted in abutment on the core 9 of said profiles 7, the adjustment being carried out by means of a key for example straddling the sides 10 in four or six sides of the shoe 1, the immobilization at the chosen setting being obtained naturally by the threads between them which are made so as to force.
