Abstract
Description
L'invention concerne un dispositif de réglage en position de deux éléments entre eux. The invention relates to a device for adjusting the position of two elements together.
L'objet de l'invention se rattache au secteur technique des dispositifs d'accouplement réglables en général, et notamment des accouplements dentés. The object of the invention relates to the technical sector of adjustable coupling devices in general, and in particular toothed couplings.
Suivant l'invention, on a voulu réaliser un dispositif de réglage en position de deux éléments entre eux qui soit de construction simple et économique, facile à manoeuvrer, et utilisable dans de nombreux domaines. According to the invention, it has been desired to provide a device for adjusting the position of two elements between them which is simple in construction and economical, easy to maneuver, and can be used in many fields.
En particulier, on s'est fixé pour but de résoudre le problème de la stabilité des équipements recevant des charges et dont le piètement doit reposer sur un sol inégal. C'est le cas notamment pour le matériel de camping (chaises, tabourets, tables, meubles, éléments de cuisine...), les matériels de stockage et de rangement, les matériels de bâtiment < échelles, escabeaux, échafaudages), les abris ou autres structures similaires. In particular, the aim has been to solve the problem of the stability of equipment receiving loads and whose base must be based on uneven ground. This is particularly the case for camping equipment (chairs, stools, tables, furniture, kitchen elements, etc.), storage and storage equipment, building materials (ladders, stools, scaffolding), shelters. or other similar structures.
Pour cela, et selon une première caractéristique, le dispositif est composé essentiellement de deux éléments dont l'un présente directement ou de manière rapportée un organe dente agencé pour autoriser le libre coulissement guidé de l'autre élément qui reçoit intérieurement un organe à denture complémen- taire, conformé pour assurer à volonté l'accouplement ou le dé- saccouplement des dentures desdits organes en fonction du positionnement relatif désiré des éléments. For this, and according to a first feature, the device is composed essentially of two elements, one of which has directly or reportedly a dente member arranged to allow free guided sliding of the other element which receives internally a complementary toothed member - silent, shaped to ensure at will coupling or decoupling of the teeth of said bodies according to the desired relative positioning of the elements.
Suivant une autre caractéristique, les dentures des deux organes sont du type "dents de loup" c'est- & dire orien tées angulairement en sens inverse pour autoriser dans un sens, le coulissement d'un des éléments par rapport a l'autre du fait du positionnement élastique d'un des organes dentés et, dans l'autre sens, le blocage en position choisie des deux éléments entre eux. According to another feature, the teeth of the two members are of the "wolf teeth" type, that is to say angularly angularly in opposite directions to allow in one direction, the sliding of one of the elements relative to the other of the makes the elastic positioning of one of the toothed members and, in the other direction, the blocking in the chosen position of the two elements together.
Ces caractéristiques et d'autres encore ressortiront de la description qui suit. These and other features will become apparent from the following description.
Pour fixer l'objet de l'invention, sans toutefois le limiter, dans le dessin annexé :
La figure 1 est une vue en perspective illustrant un exemple d'application du dispositif selon l'invention.To fix the object of the invention, without however limiting it, in the appended drawing:

La figure 5 est une vue en coupe transversale considé- rée suivant la ligne 5-5 de la figure 3. Figure 5 is a cross-sectional view taken along the line 5-5 of Figure 3.
Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant sous une forme non limitative de réalisa- tion illustrée aux figures du dessin appliquée à un tabouret, étant entendu que le dispositif selon l'invention peut être mis en oeuvre dans de nombreuses autres applications. In order to make the object of the invention more concrete, it is now described in a non-limiting embodiment illustrated in the figures of the drawing applied to a stool, it being understood that the device according to the invention can be implemented. in many other applications.
Comme on le voit à la figure 1, le tabouret (T) présente quatre pieds (T1) équipés chacun du dispositif permettant de placer le tabouret horizontalement et de manière stable en fonction des inégalités du sol. As seen in Figure 1, the stool (T) has four legs (T1) each equipped with the device for placing the stool horizontally and stably according to the inequalities of the ground.
Ce dispositif comprend essentiellement un élément (i) formant crémaillère fixe (la) portée par le pied (Ti), un é1é- ment t2) constituant un sabot denté (2a), un élément profile creux (3) formant glissière mobile et un moyen élastique (4) interposé entre le sabot et le fond (3a) de la glissière. This device essentially comprises a member (i) forming a fixed rack (1a) carried by the foot (Ti), a member t2) constituting a toothed shoe (2a), a hollow profile member (3) forming a movable slide and a means elastic (4) interposed between the shoe and the bottom (3a) of the slide.
Les dentures (la et 2a) orientées angulairement en sens inverse sont du type "dents de loup", c'est-a-dire très effilées, pour autoriser dans un sens le blocage entre le pied (Ti) et la glissière (3) et, dans l'autre sens, le réglage en hauteur par effacement des dentures du sabot écarté él asti que- ment de la crémaillère. The teeth (la and 2a) angularly oriented in the opposite direction are of the "wolf teeth" type, that is to say very tapered, to allow in one direction the locking between the foot (Ti) and the slide (3) and, in the other direction, the height adjustment by erasure of the teeth of the sabot spaced el asti queement of the rack.
Dans l'exemple illustré, la crémaillère (la) est fixée à ses extrémités sur le pied (T1) par vis (5) mais il est bien évident que le pied peut présenter directement une crémaillère dans sa partie inférieure. In the example shown, the rack (la) is fixed at its ends on the foot (T1) by screw (5) but it is obvious that the foot can directly have a rack in its lower part.
Le profilé (3) a une section rectangulaire ou carrée avec une ouverture longitudinale (3b) sur le caté en regard de la crémaillère pour s' engager à coulissement par les parties recourbées (3c) ainsi formées, derrière la crémaillère qui pr6- sente à cet effet une semelle (lb) de largeur inférieure. L'ex trémité inférieure (3f) du profilé est de préférence conformée pour constituer une base d'appui au sol. The profile (3) has a rectangular or square section with a longitudinal opening (3b) on the caté facing the rack to engage slidingly by the curved portions (3c) thus formed, behind the rack which presents to this effect a sole (lb) of smaller width. The lower end (3f) of the profile is preferably shaped to form a ground support base.
Le moyen élastique (4) peut être constitué de toute manière connue, par exemple comme ilîsutré, par deux lames (4a) (4b) en acier à ressort fixées aux extrémités du sabot et recourbées intérieurement à leur extrémité opposée, après entre écartées de l'organe denté. The resilient means (4) may be formed in any known manner, for example as illustrated, by two spring steel blades (4a) (4b) attached to the ends of the shoe and curved internally at their opposite end, after being spaced apart from the shoe. toothed organ.
Comme on l'a déjà indiqué, pour égaler la position de la glissière par rapport au pied, il suffit de faire coulisser la glissière selon flèche (F) de la figure 4, qui sous l'effet du moyen élastique et de l'orientation des dentures, échappe de la crémaillère. Néanmoins, on prévoit d'écarter manuellement le sabot par un organe de préhension (7) du type anneau ouvert par exemple, dont les branches (7a) recourbées intérieurement, traversent des ouvertures transversales oblongues (3d) des cOtés (3e) de la glissière, et s'engagent dans un orifice transversal (2b) formé dans la partie médiane du sabot. As already indicated, to equal the position of the slide relative to the foot, simply slide the slide according to arrow (F) of Figure 4, which under the effect of the elastic means and the orientation teeth, escapes from the rack. However, it is planned to manually remove the shoe by a gripping member (7) of the open ring type for example, whose branches (7a) curved internally, through oblong transverse openings (3d) side (3rd) of the slide , and engage in a transverse orifice (2b) formed in the middle portion of the shoe.
Le réglage plus ou moins important se traduit suivant le pas obtenu sur les crémaillères en fonction de l'utilisation demandée. The more or less important adjustment is reflected according to the not obtained on the racks according to the requested use.
Ce dispositif auto-bloquant est plus particulièrement destiné a équiper les sièges de plein air, tels que les tabourets et sièges de pêche, les siège et tables de camping, et en général tous les équipements mobiles à poser sur des sols ine- gaux. Cependant, il n'est pas exclu d'utiliser ce principe de liaison réglable et auto-bloquante dans d'autres applications. This self-locking device is more particularly intended to equip outdoor seats, such as stools and fishing seats, camping chairs and tables, and in general all mobile equipment to be placed on uneven floors. However, it is not excluded to use this principle of adjustable and self-locking connection in other applications.
Par exemple, on peut l'adapter aux rayonnages de meubles, d'éta- gères, de structures de stockage. Pour cela, il suffit d'inverser les dentures, c'est- & dire de disposer les crémaillères fixes avec les pointes de dents orientées vers le haut, et les sabots associés à des rayonnages avec les pointes de dents orientées vers le bas, afin d'assurer le blocage après réglage des rayons supportant les charges.For example, it can be adapted to shelving furniture, shelves, storage structures. To do this, it suffices to reverse the teeth, that is to say to arrange the fixed racks with the tips of teeth facing upwards, and the hooves associated with shelves with the tips of teeth pointing downwards, so to ensure the blocking after adjustment of the spokes supporting the loads.
S la limite, il n'est pas exclu de prévoir des dentures tla et 2a) symétriques ou à profil en triangle équilatéral ou isocèle, cSest-å-dire non orientées, si l'on veut obtenir un réglage dans les deux sens des éléments dentés entre eux, avec seulement un blocage en position par interliaison des dents ou par inclinaison des ouvertures oblongues (3d) ; cela dans le cas où aucune charge n'est prévue sur l'un des éléments. At the limit, it is not excluded to provide symmetrical or equilateral or isosceles triangular teeth, tla and 2a), that is to say unoriented, if a two-way adjustment of the elements is to be obtained. toothed between them, with only a locking in position by interliaison of the teeth or by inclination of the oblong openings (3d); this in the case where no load is provided on one of the elements.
Les avantages ressortent bien de la description. On souligne notamment la possibilité de régler facilement en hauteur des piétements d'équipements de plein air å poser sur des sols inégaux. The advantages are apparent from the description. In particular, it is possible to easily adjust the height of outdoor equipment bases to be installed on uneven floors.
