Description

La présente invention concerne une ferrure de tête articulée pour échelles ou escaliers de grenier escamotables, articulée d'une part sur le haut de la trappe et, d'autre part, sur un coulisseau sur lequel coulisse une échelle ou un escalier de grenier escamotable. L'état de la technique propose :

  • - soit des échelles constituées d'un tronçon supérieur articulé sur le bord inférieur de la trappe (bas du hourdis ou caisson) et sur lequel vient coulisser ou se replier un ou plusieurs tronçons inférieurs et/ou intermédiaires d'une dimension égale ou inférieureau tronçon supérieur. Ce type d'échelles ou d'escaliers qui s'escamote soit dans le volume de la trappe ou directement dessus, a pour principal inconvénient de nécessiter une trappe dont la longueur soit au minimum celle du plus long tronçon de l'échelle.
  • - soit des échelles constituées d'un tronçon supérieur articulé sur le bord supérieur de la trappe (haut du hourdis ou du caisson) et sur lequel vient coulisser un ou plusieurs tronçons plus longs que le tronçon supérieur.
The present invention relates to an articulated head fitting for retractable attic ladders or stairs, articulated on the one hand on the top of the hatch and, on the other hand, on a slide on which slides a ladder or a retractable attic staircase. The state of the art offers:
  • - or ladders consisting of an upper section articulated on the lower edge of the hatch (bottom of the slab or box) and on which slides or folds one or more lower and / or intermediate sections of equal or lower dimension superior. The main drawback of this type of ladder or staircase, which either retracts into the volume of the hatch or directly above it, requires a hatch whose length is at least that of the longest section of the ladder.
  • - or ladders consisting of an upper section articulated on the upper edge of the hatch (top of the slab or box) and on which slides one or more sections longer than the upper section.

Une fois escamotés, ces échelles ou escaliers reposent pour une partie sur le plancher de l'étage supérieur et pour une autre partie au dessus de la trappe. Ce dernier type d'échelles ou d'escaliers escamotables présente deux autres inconvénients majeurs : d'une part, il est fréquent que le rayon de dégagement nécessaire au repliage ne soit pas disponible et ceci en raison de la configuration du grenier, à l'étage supérieur, par rapport à la trappe (proximité d'un mur, d'une poutre ou de la toiture); d'autre part, ces mêmes échelles qui prennent appui sur la partie supérieure de la trappe encombrent toujours une partie de cette dernière en position dépliée du fait de leur inclinaison nécessaireOnce retracted, these ladders or stairs rest partly on the floor of the upper floor and for another part above the hatch. This last type of retractable ladders or stairs has two other major drawbacks: firstly, it is frequent that the clearance radius required for folding is not available and this due to the configuration of the attic, upper floor, in relation to the hatch (proximity to a wall, a beam or the roof); on the other hand, these same ladders which bear on the upper part of the hatch always clutter up part of the latter in the unfolded position due to their necessary inclination

En résumé, il est donc impossible d'équiper un trou de 500 m/m x 400 m/m avec ce type d'échelles tout en laissant le passage nécessaire à un homme.In summary, it is therefore impossible to equip a hole of 500 m / m x 400 m / m with this type of ladder while leaving the necessary passage for a man.

L'objet de la présente invention concerne une ferrure de tête articulée pour une échelle ou un escalier de grenier escamotable constituée de deux bras porteurs articulés à leur extrémité supérieure sur deux étriers fixés sur la partie haute de la trappe et à leur extrémité inférieure sur deux coulisseaux sur lesquels vient coulisser le tronçon supérieur de l'échelle ou de l'escalier de grenier escamotable. ;The object of the present invention relates to an articulated head fitting for a ladder or a retractable attic staircase consisting of two carrying arms articulated at their upper end on two brackets fixed on the upper part of the hatch and at their lower end on two runners on which the upper section of the ladder or retractable attic staircase slides. ;

Les avantages obtenus grâce à cette invention sont :

  • - de réduire considérablement l'encombrement de l'échelle ou de l'escalier dans la trappe, lorsqu'il est en position dépliée.
  • - de permettre de replier à volonté l'échelle ou l'escalier de grenier escamotable d'un côté ou de l'autre de la trappe selon la configuration de l'étage supérieur (mur, toiture, poutre, etc...).
  • - de permettre l'utilisation de tous les types d'échelles ou d'escaliers de grenier escamotables dans une trappe aux dimensions les plus réduites, jusqu'au simple trou d'homme (400 m/m x 500 m/m).
The advantages obtained thanks to this invention are:
  • - considerably reduce the size of the ladder or the staircase in the hatch, when it is in the unfolded position.
  • - allow the ladder or retractable attic staircase to be folded at will on one side or the other of the hatch depending on the configuration of the upper floor (wall, roof, beam, etc.).
  • - to allow the use of all types of retractable attic ladders or attic in a hatch with the smallest dimensions, up to a simple manhole (400 m / mx 500 m / m).

Dans ce qui suit, l'invention est exposée plus en détail à l'aide de dessins représentant un mode d'exécution.

Suivant figures 1, 2 et 3, la ferrure de tête articulée pour échelle ou escalier de grenier escamotable est composée de deux bras porteurs (1). Ces deux bras porteurs sont articulés autour d'un axe (3) fileté à ses deux extrémités et reposant sur deux étriers (2) solidaires de la solive de la trappe au moyen de tire-fonds (16). L'assemblage libre en rotation des deux bras porteurs (1) de l'axe (3) et des deux étriers (2) est obtenu au moyen de deux écrous (4) et de deux rondelles ressort (5) vissées sur les deux extrémités filetées du dit axe (3). Cette dernière disposition permet d'obtenir un frottement à la rotation offrant la possibilité de maintenir les bras porteurs (1) dans la position souhaitée pendant la manipulation de l'échelle ou de l'escalier de grenier escamotable.According to Figures 1, 2 and 3, the hinged head fitting for a ladder or retractable attic staircase is composed of two carrying arms (1). These two carrying arms are articulated around an axis (3) threaded at its two ends and resting on two stirrups (2) secured to the joist of the hatch by means of lag screws (16). The free assembly in rotation of the two carrying arms (1) of the axis (3) and the two brackets (2) is obtained by means of two nuts (4) and two spring washers (5) screwed on the two ends threaded on said axis (3). This latter arrangement makes it possible to obtain friction on rotation, offering the possibility of maintaining the carrying arms (1) in the desired position during the handling of the ladder or of the retractable attic staircase.

Suivant une autre particularité (figures 2 et 3) une poignée (6) escamotable le long d'un des deux bras porteurs (1) libre en rotation autour de l'axe (3) au moyen d'un écrou (4) et d'une rondelle (5) et munie d'une butée (15) permet le pivotement vers le haut des deux bras porteurs (1) nécessaire à la préhension de l'échelle ou de l'escalier de grenier escamotable pour son pliage depuis l'étage supérieur. ;According to another feature (Figures 2 and 3) a handle (6) retractable along one of the two carrying arms (1) free to rotate about the axis (3) by means of a nut (4) and d '' a washer (5) and provided with a stop (15) allows the pivoting upwards of the two carrying arms (1) necessary for the gripping of the ladder or of the retractable attic staircase for its folding from the upper floor. ;

Toujours suivant figures 2 et 3, l'autre extrémité des deux bras porteurs (1) est articulée sur deux coulisseaux (7) au moyen de deux vis (8) et leur écrou (9).Still according to FIGS. 2 and 3, the other end of the two support arms (1) is articulated on two slides (7) by means of two screws (8) and their nut (9).

Ces deux coulisseaux (7) tiennent lieu de glissière au tronçon supérieur de l'échelle ou de l'escalier de grenier escamotable.These two slides (7) take the place of a slide at the upper section of the ladder or the retractable attic staircase.

Une butée (13) fixée sur l'extrémité du tronçon supérieur de l'échelle ou de l'escalier de grenier escamotable empêche ce dernier de sortir du coulisseau (7).A stop (13) fixed on the end of the upper section of the ladder or of the retractable attic staircase prevents the latter from coming out of the slide (7).

Une butée (14) réglable en hauteur sur le tronçon supérieur de l'échelle ou de l'escalier de grenier escamotable vient limiter la course du dit tronçon lors du pliage.A stop (14) adjustable in height on the upper section of the ladder or of the retractable attic staircase limits the travel of said section during folding.

Toujours selon figure 2, un cliquet (10) permet d'immobiliser le tronçon supérieur de l'échelle ou de l'escalier de grenier escamotable sur le coulisseau (7). Ce cliquet (10) libre en rotation pivote sous l'effet de son propre poids autour d'un axe (11) et possède un ergot (12).Still according to FIG. 2, a pawl (10) makes it possible to immobilize the upper section of the ladder or of the retractable attic staircase on the slide (7). This ratchet (10) free to rotate pivots under the effect of its own weight around an axis (11) and has a lug (12).

Le pliage et le dépliage de l'échelle pu de l'escalier de grenier escamotable s'effectue suivant le mode opératoire suivant.

  • - la figure 4 illustre le.processus de pliage du côté des deux étriers (2) fixés sur la partie haute de la solive. En position A les tronçons de l'échelle ou de l'escalier de grenier escamotable sont superposés et bloqués entre eux. En levant l'échelle, grâce au cliquet (10) venant buter sur le coulisseau (7), figure 2, la ferrure de tête articulée pivotera vers le haut.pour passer de la position A à la position B.
The folding and unfolding of the ladder pu of the retractable attic staircase is carried out according to the following operating mode.
  • - Figure 4 illustrates the folding process of the side of the two stirrups (2) fixed on the upper part of the joist. In position A, the sections of the ladder or the retractable attic staircase are superimposed and locked together. By raising the ladder, thanks to the pawl (10) abutting on the slide (7), Figure 2, the articulated head fitting will pivot upwards. To pass from position A to position B.

Dans la position B, l'ergot (12) prend appui sur le bras porteur (1) et libère le cliquet (10) permettant le glissement de l'échelle sur le coulisseau (7).In position B, the lug (12) bears on the support arm (1) and releases the pawl (10) allowing the ladder to slide on the slide (7).

Le prolongement de ce coulissement, suivi d'un basculement de l'échelle ou de l'escalier de grenier escamotable, permet de passer de la position B à la position C.The extension of this sliding, followed by a tilting of the ladder or the retractable attic staircase, makes it possible to pass from position B to position C.

- la figure 5 montre une possibilité d'escamotage de l'échelle ou de l'escalier de grenier sans aucun dépassement ou dessus de la trappe.- Figure 5 shows a possibility of retracting the ladder or the attic staircase without any overshoot or above the hatch.

L'utilisateur a la possibilité de passer de la position C, représentée sur la figure 4, à la position I (figure 5) en réglant en conséquence la butée (14) qui limite à volonté la course de coulissement.The user has the possibility of passing from position C, shown in FIG. 4, to position I (FIG. 5) by adjusting the stop (14) accordingly which limits the sliding stroke as desired.

- la figure 6, illustre le processus dé pliage de l'échelle ou de l'escalier de grenier escamotable du côté opposé aux deux étriers (2).- Figure 6 illustrates the process of folding the ladder or the retractable attic staircase on the side opposite the two stirrups (2).

En levant l'échelle, grâce au cliquet (10) venant buter sur le coulisseau (7) la ferrure de tête articulée pivote vers le haut pour passer de la position D à la position E.By lifting the ladder, thanks to the pawl (10) abutting on the slide (7), the articulated head fitting pivots upwards to pass from position D to position E.

En position E, le cliquet (10) pivote sous son propre poids et libère le coulisseau (7).In position E, the pawl (10) pivots under its own weight and releases the slide (7).

Le glissement à volonté devient alors possible pour passer de la position E à la position F.The sliding at will then becomes possible to pass from position E to position F.

Enfin, l'utilisateur a la possibilité de plier l'échelle ou l'escalier de grenier escamotable depuis l'étage supérieur suivant le mode opératoire ci-après.Finally, the user has the possibility of folding the ladder or the retractable attic staircase from the upper floor according to the following operating mode.

- tirer la poignée de manoeuvre (6) jusqu'à ce que la butée (15) vienne prendre appui sur l'un des deux bras porteurs (1) de la ferrure de tête articulée.- pull the operating handle (6) until the stop (15) comes to bear on one of the two carrying arms (1) of the articulated head fitting.

- ladite ferrure de tête pivotant alors vers le haut, permet à l'utilisateur d'attraper le tronçon supérieur de l'échelle ou de l'escalier.- Said head fitting then pivoting upwards, allows the user to catch the upper section of the ladder or the staircase.

- l'utilisateur a alors la possibilité de plier son échelle soit en position C (figure 4) soit en position 1 (figure 5) soit en position F (figure 6).- the user then has the possibility of folding his ladder either in position C (figure 4) or in position 1 (figure 5) or in position F (figure 6).
