Abstract

The press assembles the bars, stringboard and rail of a wooden staircase, having a first clamp (1) gripping the rail, a second (7) gripping the stringboard, and a screw jack (4,5) on which a considerable force can be exerted, irrespective of the bannister dimensions. The clamps can be pivot-mounted to tilt in all directions, being lockable by handles (3,6) in the desired angular positions.

Description

L'invention concerne un dispositif permettant d'assembler les barreaux sur les lisses et limons des escaliers en bois. Les barreaux, munis de tenons à chaque extrémité, doivent être emboités dans les mortaises pratiquees sur 1 lisses et les limons. Cette opération est difficile à réaliser dans appareil spécial, les parties à serrer etant inclines, souvent sous des angles importants (300 à 60 ) et les emboitements nécessitant des efforts importants. The invention relates to a device for assembling the bars on the rails and stringers of wooden stairs. The bars, provided with tenons at each end, must be fitted into the mortises made on 1 rails and the stringers. This operation is difficult to carry out in a special apparatus, the parts to be clamped being inclined, often at large angles (300 to 60) and the sockets requiring significant efforts.

Jusqu'ici les fabricants d'escaliers faisaient appel à des appareils de serrage non adaptés, du type "serre-joint classique" qui étaient maintenus tant bien que mal dans des positions souvent aleatoires. Cette opération etai longue et délicate et risquait d'abimer les pièces en bois par suite de glissement des serre-joints. Until now, stair manufacturers used unsuitable clamping devices, of the "classic clamp" type, which were held up as best they could in often random positions. This operation was long and delicate and risked damaging the wooden parts as a result of slipping of the clamps.

L'appareil permet donc l'emboitement des trois parties de la rampe d'escalier, ceci sans abimer les pièces serrées (lisse et limon) et en exerçant des efforts dans la direction exacte nécessaire pour l'opération désirée, don sans déformer les parallélogrammes formés par la lisse, le limon et les barre
L'appareil comprend une presse 1 venant se serrer sur la lisse a, une pr se 7 venant se serrer sur le limon C. Ces deux presses sont articulées de fa çon à prendre l'inclinaison de la rampe d'escalier et bloquées dans cette position à l'aide des poignées 3 et 6. La liaison entre ces 2 presses est reali sée à l'aide d'une barre de longueur variable en deux parties 4 et 5 coulissant l'une dans l'autre.The device therefore allows the interlocking of the three parts of the stair railing, this without damaging the tight parts (smooth and stringer) and by exerting forces in the exact direction necessary for the desired operation, don without distorting the parallelograms formed by the stringer, the stringer and the bars
The apparatus comprises a press 1 coming to clamp on the stringer a, a pr 7 coming to clamp on the stringer C. These two presses are articulated so as to take the inclination of the stair railing and locked in this position using handles 3 and 6. The connection between these 2 presses is carried out using a bar of variable length in two parts 4 and 5 sliding one inside the other.

Le rapprochement des deux presses 1 et 7, provoquant l'emboitement des tenons et mortaises, est réalise par la commande 2 d'une vis à filet trapeso dal qui tend à faire coulisser 5 dans 4. The bringing together of the two presses 1 and 7, causing the interlocking of the tenons and mortises, is carried out by the control 2 of a trapeso dal thread screw which tends to slide 5 in 4.

Naturellement, la description et le dessin ne sont donnés qu'à titre ind catif, nullement limitatif. Naturally, the description and the drawing are given for information only, in no way limiting.

Cette nouvelle presse d'assemblage pour escalier peut être adaptée à tous les escaliers en bois ou autres materiaux pour lesquels un emhoitement est nécessaire, ainsi qu'aux escaliers en fer pour le maintien des barreaux pendant leur soudage entre les lisses haute et basse. Elle est adaptée, de pat la rotation sur 360" de ses 2 presses d'extrémité, à toutes les figures posai bles d'escaliers. This new stair assembly press can be adapted to all wooden staircases or other materials for which interlocking is necessary, as well as to iron staircases for holding the bars during their welding between the top and bottom rails. It is adapted, from the 360 "rotation of its 2 end presses, to all posai ble staircase figures.

'est un appareil mobile au départ, pouvant servir sur chantier. Mais il peut être adapté à un travail à poste fixe et par batteries de deux ou troi appareils fixes3 être utilisé pour des fabrications d'escaliers en série.  is a mobile device at the start, which can be used on site. But it can be adapted to work at a fixed station and by batteries of two or three fixed devices3 be used for mass production of stairs.
