Abstract
Description
La présente invention a trait à la réalisation des escaliers pour locaux d'habitation et similaires, et elle vise plus 'particulièrement (car c'est dans ce cas que son application semble présenter le plus d'intérêt), mais non exclusivement, les escaliers du type dit à vis ou
en spirale", en vue d'en faciliter la construction et l'adaptation tout en en améliorant la solidité et l'aspect esthétique.The present invention relates to the production of stairs for living quarters and the like, and it is more particularly (because it is in this case that its application seems to be of most interest), but not exclusively, the stairs of the screw type or
in spiral ", in order to facilitate its construction and adaptation while improving its solidity and the aesthetic aspect.
L'escalier suivant l'invention est principalement remarquable en ce que son limon est constitué par au moins une série de montants qui prennent appui sur le sol et dont chacun est assemblé à une contremarche par un tirant horizontal qui assure simultanément la. fixation de la base d'un support extérieur de rampe, des moyens appropriés étant prévus pour assurer la solidarisation de chaque contremarche à la marche immédiatement inférieure. The staircase according to the invention is mainly remarkable in that its stringer is constituted by at least one series of uprights which bear on the ground and each of which is assembled to a riser by a horizontal tie which simultaneously ensures the. fixing of the base of an external ramp support, suitable means being provided to secure the joining of each riser to the next lower step.
Conformément à un mode de mise en oeuvre préféré de la disposition qui précède, les montants qui constituent le limon sont en nombre égal à celui des marches de l'escalier et sont assemblés les uns aux autres par des goussets convenablement profilés. Ces montants se prolongent d'une hauteur égale au-dessus de chaque marche afin de supporter une rampe intérieure ou de former une sorte de garde-corps intérieur. In accordance with a preferred embodiment of the above arrangement, the uprights which constitute the stringer are in number equal to that of the steps of the staircase and are joined to each other by suitably profiled gussets. These uprights extend by an equal height above each step in order to support an interior ramp or to form a kind of interior railing.
Le, dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une vue partielle en perspective d'un escalier à vis établi conformément à l'invention.The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is likely to provide.

Fig. 5 est une coupe transversale suivant le plan indiqué en
V-V en fig. 4.Fig. 5 is a cross section along the plane indicated in
VV in fig. 4.
Le support ou limon de l'escalier représenté en fig. 1 est constitué par une série de chevrons verticaux ou montants 1, à section rectangulaire dans l'exemple de réalisation envisagé. Ces montants 1, disposés suivant une portion de circonférence et prévus en nombre égal à celui des marches de l'escalier, sont assemblés les uns aux autres par des goussets 2 (voir fig. 2) convenablement cintrés, susceptibles d'être établis en contreplaqué ou en métal. L'on observera que la hauteur des montants 1 va en croissant régulieremenr d d' me extrémité a l'autre de l'escalier, comme on le comprendra mieux ci-apres. The support or stringer of the staircase shown in fig. 1 is constituted by a series of vertical rafters or uprights 1, of rectangular section in the exemplary embodiment envisaged. These uprights 1, arranged along a portion of the circumference and provided in a number equal to that of the steps of the staircase, are joined to each other by gussets 2 (see fig. 2) suitably bent, capable of being established in plywood or metal. It will be observed that the height of the uprights 1 increases steadily from one end to the other of the staircase, as will be better understood below.
F.g. 3 fait bien apparaître le profil de chaque marche 3, en forme de triangle tronqué. Au voisinage de son bord antérieur, chacune de ces marches 3 est creusée d'une rainure longitudinale 3a qui s'ouvre vers le bas, afin de permettre l'assemblage de la marche envisagée avec la contremarche 4 immédiatement inférieure. Chaque contre-marche 4, découpée sur son bord inférieur en 4a afin de déterminer deux appuis latéraux, comporte sur son bord supérieur une languette ou tenon longitudinal 4b, dont la hauteur est inférieure à la profondeur de la rainure 3a sus-mentionnée. On notera encore que chacun des bords verticaux de la contremarche 4 est pourvu d'une oreille latérale 4c, prévue au niveau du bord horizontal inférieur libre de chaque appui. F.g. 3 clearly shows the profile of each step 3, in the shape of a truncated triangle. In the vicinity of its front edge, each of these steps 3 is hollowed out with a longitudinal groove 3a which opens downward, in order to allow the assembly of the step envisaged with the riser 4 immediately below. Each step 4, cut on its lower edge at 4a to determine two lateral supports, has on its upper edge a tongue or longitudinal pin 4b, the height of which is less than the depth of the groove 3a mentioned above. It will also be noted that each of the vertical edges of the riser 4 is provided with a lateral lug 4c, provided at the level of the free lower horizontal edge of each support.
Comme plus particulierement montré en fig. 4, ces oreilles latérales 4c sont destinées à venir s'engager dans des logements la et 5a, respectivement creusés dans la face extérieure de chaque montant 1 et dans la face intérieure de la base d'une série de supports verticaux 5, en nombre égal à celui des montants précités. Une fois ce positionnement ainsi effectué, on dispose au-dessus de la contremarche 4 considérée une marche 3, en prenant soin que la rainure 3a de celle-ci vienne coiffer en quelque sorte la languette 4b de ladite contremarche. Dans l'espace longitudinal de la rainure 3a qui n'est pas occupé par la languette 4b est inséré un tirant ou tringle 6 qui traverse des perforations lb et 5b, respectivement ménagées dans la base des montants 1 et des supports 5, au-dessus des logements la et 5a. As more particularly shown in FIG. 4, these lateral ears 4c are intended to engage in housings 1a and 5a, respectively hollowed out in the external face of each upright 1 and in the internal face of the base of a series of vertical supports 5, in equal number to that of the aforementioned amounts. Once this positioning has been carried out in this way, there is a step 3 above the riser 4 considered, taking care that the groove 3a of the latter comes in some way to cover the tongue 4b of said riser. In the longitudinal space of the groove 3a which is not occupied by the tongue 4b is inserted a tie rod or rod 6 which crosses perforations 1b and 5b, respectively formed in the base of the uprights 1 and the supports 5, above housing la and 5a.
La tête 6a de chaque tirant 6 vient s'appliquer contre la face extérieure du support vertical 5 correspondant, tandis que son extrémité filetée reçoit, au-delà de la perforation lb, une rondelle et un écrou 6b. On conçoit que le serrage à force de cet écrou 6b assure l'assemblage rigide des pièces 1, 3, 4 et 5 qui constituent alors un ensemble stable et résistant ; la marche 3 est soutenue par le tirant 6 qui opère simultanément la retenue de la contremarche par pincement. The head 6a of each tie rod 6 is applied against the outer face of the corresponding vertical support 5, while its threaded end receives, beyond the perforation lb, a washer and a nut 6b. It is understood that the tightening by force of this nut 6b ensures the rigid assembly of the parts 1, 3, 4 and 5 which then constitute a stable and resistant assembly; the step 3 is supported by the tie rod 6 which simultaneously operates the retention of the riser by pinching.
Pour parfaire cet assemblage on a avantageusement recours, au niveau de chaque marche 3, à un tire-fond vertical 7 qui traverse une perforation 3b pratiquée au voisinage du bord arrière des marches et qui s'engage dans un forage transversal borgne 4d (fig. 4 et 5) prévu dans les contremarches 4. Le serrage des tire-fond 7 renforce évidemment la fixation des marches et des contremarches de l'escalier ; on notera que cette action s'effectue dans une épaisseur restreinte du bois de la contremarche, si bien que les effets de séchage seront moins ressentis sur l'ensemble de l'ouvrage. To complete this assembly, advantageously, at each step 3, recourse is had to a vertical lag screw 7 which passes through a perforation 3b made in the vicinity of the rear edge of the steps and which engages in a blind transverse drilling 4d (FIG. 4 and 5) provided in the risers 4. The tightening of the lag bolts 7 obviously strengthens the fixing of the steps and the risers of the staircase; it will be noted that this action is carried out in a restricted thickness of the wood of the riser, so that the drying effects will be less felt on the whole of the structure.
Les montants 1 du limon et les supports verticaux 5 sont établis de façon à dépasser d'une hauteur égale au-dessus de la marche 3 corres pondante, de telle sorte que les montants précités forment une sorte de garde-fou intérieur tandis que les supports peuvent être équipés à leur soumet d'une rampe extérieure 8, comme illustré en fig. 1. The uprights 1 of the stringer and the vertical supports 5 are established so as to protrude by an equal height above the corresponding step 3, so that the abovementioned uprights form a kind of internal railing while the supports can be equipped with an external ramp 8 as shown in FIG. 1.
I1 doit d'ailleurs être entendu que la description qui précede n'a été donnée qu'à titre d'exemple etqu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents. On conçoit en particulier que la réalisation du limon peut faire l'objet d'une foule de variantes, en fonction notamment de la conformation et de l'agencement du local destiné à recevoir l'escalier. It should moreover be understood that the foregoing description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents. It is understood in particular that the production of the stringer can be the subject of a host of variants, depending in particular on the conformation and the arrangement of the room intended to receive the staircase.
