Abstract

The device has a roller (1) mounted on a shaft (2) that translatively moves by two cap nuts (3) and stainless steel washers (7) in a cover (4). The cover is welded onto two curved tubes (5) that are fixed on a plate (6). The roller is arranged relative to the cover formed by the curved tubes. The tubes are bent at an angle of 90 degrees to allow passage of a rope on the roller. The washers are positioned at each side of the roller. Each tube has a vertical portion for horizontally guiding the rope. The tubes have a plastic stopper at its ends, and the roller is made of white nylon.

Description

La présente invention concerne un dispositif pour relever une charge à l'aide d'une corde en limitant les efforts et les frottements. Le dispositif est constitué d'un rouleau horizontal et perpendiculaire à la corde qui assure son changement de direction tout en l'éloignant à distance de son support. The present invention relates to a device for lifting a load using a rope by limiting the forces and friction. The device consists of a horizontal roller and perpendicular to the rope which ensures its change of direction while moving away from its support.

Le rouleau est en rotation sur un axe dans une chape constituée de deux tôles percées et soudées chacune sur un tube cintré à 90°. Le cintrage de ces deux tubes assure dans toutes les directions, le guidage de la corde vers le rouleau. Les parties droites et verticales de ces tubes permettent de guider les cordages et 10 d'assurer une reprise de charge réalisée par un tour mort du cordage. Les parties droites horizontales de ces tubes sont soudées sur une platine permettant l'adaptation et l'ancrage à de multiples supports. La platine dispose de perçages de différentes configurations afin de s'ancrer à tout support rigide. 15 A titre d'exemple non limitatif, le dispositif objet de l'invention pourrait s'adapter sur un bordé de bateau, un quai ou un portique de manutention, un élément d'échafaudage etc.... Le dispositif peut avoir des dimensions variables afm de s'adapter aux différents contextes d'utilisation. 20 A titre d'exemple non limitatif : - Le rouleau aura un diamètre de 70 mm et une longueur de 200 mm. - Les tubes cintrés à 90° qui le supportent auront un diamètre 20/27 (intérieur/extérieur). L'extrémité de ces tubes pourra comporter un bouchon plastique pour éviter tout risque de blessure... 25 - Le dispositif pourra être par exemple, en acier inoxydable. Le rouleau pourra être par exemple, en nylon blanc ou P.E.H.D. de manière à rendre la manutention silencieuse et donner de l'esthétique à l'ensemble. Les tôles constituant la chape, assurant le supportage et le guidage du rouleau seront positionnées et soudées à l'intérieur du cintrage et excentrées tangentiellement à 30 l'extérieur des tubes de manière à ce que le cordage ne puisse pas se coincer entre le rouleau et un des deux tubes. L'axe, assurant le guidage en rotation du rouleau, sera maintenu sur la chape par un dispositif qui l'empêchera de glisser en translation. - 2/3 - The roller is rotated on an axis in a yoke consisting of two pierced sheets and each welded to a tube bent at 90 °. The bending of these two tubes ensures in all directions, guiding the rope to the roller. The straight and vertical portions of these tubes serve to guide the ropes and to ensure a recovery of load achieved by a dead turn of the rope. The horizontal straight portions of these tubes are welded to a plate allowing adaptation and anchoring to multiple supports. The plate has holes of different configurations to anchor to any rigid support. By way of non-limiting example, the device according to the invention could be adapted to a boat plating, a loading dock or gantry, a scaffolding element, etc. The device can have dimensions variables to adapt to different contexts of use. By way of non-limiting example: The roll will have a diameter of 70 mm and a length of 200 mm. - The 90 ° bent tubes that support it will have a diameter of 20/27 (inside / outside). The end of these tubes may include a plastic plug to prevent any risk of injury ... 25 - The device may be for example, stainless steel. The roller may be, for example, white nylon or P.E.H.D. in order to make the handling silent and give aesthetics to the whole. The sheets constituting the yoke, ensuring the support and guidance of the roller will be positioned and welded inside the bending and eccentric tangential to the outside of the tubes so that the rope can not get caught between the roll and one of the two tubes. The axis, ensuring the rotational guidance of the roller, will be held on the yoke by a device that will prevent it from slipping in translation. - 2/3 -

Le croquis montre à titre d'exemple, un système vis-écrou borgne. Cette solution présente l'avantage de rendre le rouleau démontable pour être changé. Cette solution permet également d'arrondir les extrémités de l'axe et donc non blessantes pour l'utilisateur. The sketch shows as an example, a blind screw-nut system. This solution has the advantage of making the roll removable to be changed. This solution also rounds the ends of the axis and therefore not harmful to the user.

Le rouleau sera déporté par rapport à la platine support de manière à ce que le cordage ne puisse pas frotter sur le support ou une structure constituant ce support. Ce débord pourra être différent selon les cas ou, en option, être réglable. Le dispositif selon l'intervention est particulièrement destiné à la remontée de matériel surmonté d'un cordage. (Exemple d'application : Remonte nasse pour pêcheur plaisancier en bateau). Les dessins annexés illustrent l'invention figure 1, figure 2 en coupe, figure 3, Figure 4, figure 5, figure 6 et figure 7. The roller will be offset relative to the support plate so that the rope can not rub on the support or a structure constituting the support. This overflow may be different depending on the case or, optionally, be adjustable. The device according to the intervention is particularly intended for the recovery of material surmounted by a rope. (Example of application: Rowing boat fisherman boater). The accompanying drawings illustrate the invention FIG. 1, FIG. 2 in section, FIG. 3, FIG. 4, FIG. 5, FIG. 6 and FIG.

Claims

REVENDICATIONS1. Device for passing a line on a roll CLAIMS1. Device for passing a rope on a roller and between two round and curved tubes for hoisting by reducing the effort and turn a load surmounted by this rope, characterized by the arrangement of the roller relative to the yoke formed by the two tubes.

2. Device consisting of a roller (1) mounted on an axis (2) immobilized by two blind nuts (3) and washers (7) in a yoke (4) welded on bent tubes (5) fixed on plate (6) .

3. Device according to claim 1, the proportions of dimensions and positioning between the roller (1) and the bent tubes (5) prevent jamming of the rope regardless of its angle on either side of the roller.

4. Device according to any one of the preceding claims, characterized in that the bending at 90 ° of each of the two tubes promotes the passage of the rope - coming from below - on the roller and, whatever the orientation of this rope.

5. Device according to any one of the preceding claims characterized in that the offset of the roller (1) by providing the plate (6) prevents the friction of the rope on the support of the device.

6. Device according to any one of the preceding claims characterized in that the bent tubes (5) comprises a vertical portion which ensures the guiding of the lines in horizontal and the momentary attachment of the load by one or more turns of dead rope.
