Abstract

The invention relates to a device making it possible to lift covers with ease without the risk of injury to the user, the device being easily transportable via its folding system, and simple to operate owing to the presence of wheels (4, 14). It is made up of a frame (17) equipped with wheels (4, 14), a lever arm (3) of adjustable supports (6) with hooks (5) for fixing the cover to be lifted. When the user exerts pressure on the lever (3) after having selected the operation, on the grip (10), the cover is lifted without effort and by a single individual. The device according to the invention is particularly intended for opening covers in complete safety.

Description

La presente invention concerne un disposr@@ pour lever les plaques sur chaussées et trottoirs de tous types munis de systeme d'ancrages pour y permettre l'accrochage de celle-ci. The present invention relates to a disposr @@ for lifting the plates on pavements and sidewalks of all types provided with anchoring system to allow the attachment thereof.

L'ouverture de ces plaques est traditionnellement effectué à l'aide de crochets ou de bras de leviers de différents types. The opening of these plates is traditionally carried out using hooks or lever arms of different types.

île entraine beaucoup d'efforts physiques, de nombreux accidents (lombaires, membres inferieurs et superieurs) et risques de chute de la plaque dans l'orifice.  The island involves a lot of physical effort, numerous accidents (lumbar, lower and upper limbs) and risks of the plate falling into the orifice.

Le dispositif selon l'invention permet de remedier à ces inconveniants.Cet appareil constitué d'un cadre et muni de roues articulé par levier permet sans effort de decoller et de soulever ces plaques par une seule personne, et d'en assurer le transport, celle-ci evoluant sur roues. The device according to the invention makes it possible to remedy these drawbacks. This device consisting of a frame and provided with wheels articulated by lever allows effortlessly to take off and lift these plates by a single person, and to ensure their transport, it evolves on wheels.

Figure 9,10 shows the detail of the front and rear wheels.

La figure Il represente les differentes possibilités de reglage pour l'accrochage des plaques (visibles sur les figures 1, 8,9,10). Figure It represents the different adjustment possibilities for hooking the plates (visible in Figures 1, 8,9,10).

Ce prototype est fabriqué en métal (fer) zonais peut être fabriqué par un matériaux plus léger.En reference à ces dessins,cet appareil plié (fig I) permet de reduire son volume afin de permettre le transport et la manipulation par une seule personne. This prototype is made of metal (iron) from Zones and can be made from a lighter material. With reference to these drawings, this folded device (fig I) makes it possible to reduce its volume in order to allow transport and handling by a single person.

Le depliage s'effectue par son système de charnières (i) et par un cardan télescopique (2). L'appareil déplié est complété par son levier (3) qui permet le levage et le déplacement à l'aide de ses roues (4). IL se juxtapose sur la plaque, ses roues à ltexterieur du cadre. The unfolding is carried out by its hinge system (i) and by a telescopic gimbal (2). The unfolded device is completed by its lever (3) which allows lifting and movement using its wheels (4). IT juxtaposes on the plate, its wheels outside the frame.

Les crochets (5) après pose et reglage des supports (6) dans les trous (7) correspondant à la plaque choisie, son introduits dans les gorges de la plaque. IL sont alors mis sous tension à l'aide du système de serrage (8). L'appareil doit être mis sur la position M (9) par l'intermediaire d'une poignée (10). Par une pression sur le levier (3) vers le bas la plaque se décolle (fig 5) le levier (3) est en position d'attente du levage, maintenu par un système cranté (16) bloqué par un cliquet (I2). The hooks (5) after fitting and adjusting the supports (6) in the holes (7) corresponding to the chosen plate, are introduced into the grooves of the plate. They are then energized using the clamping system (8). The device must be put in position M (9) by means of a handle (10). By pressing the lever (3) down the plate comes off (fig 5) the lever (3) is in the standby position for lifting, held by a notched system (16) blocked by a pawl (I2).

Les roues (4) effectuent une rotation par l'intermédiaire de l'axe (II) et des biéllettes (13). The wheels (4) rotate through the axle (II) and connecting rods (13).

Pour le levage définitif de la plaque, continuer la pres
sion sur le levier (3), les roues (I4) continuer.t leur rotation, le
levier se trouve en position basse, maintenu par son système de cli
quet (I2).For the final lifting of the plate, continue the pres
the lever (3), the wheels (I4) continue to rotate, the
lever is in the low position, maintained by its cli system
quet (I2).

La plaque est alors soulevée (fig 6), elle peut être
dégagée en toute sécurité en manoeuvrant le lève plaque à l'aide de
ses roues (14).The plate is then lifted (fig 6), it can be
safely released by operating the plate lifter using
its wheels (14).

Pour déposer la plaque au sol ou la replacer dans son ca
dre il faut inverser la manoeuvre poignée (10) position sur D (15) exercer une légère pression sur le bras de levier (3) vers le bas.To place the plate on the ground or replace it in its ca
dre you must reverse the handle operation (10) position on D (15) exert a slight pressure on the lever arm (3) downwards.

En maintenant le bras de levier (3) sans effort, la plaque
descend dans sa position initiale.Keeping the lever arm (3) effortlessly, the plate
descends to its original position.

Le lève plaque reste immobile pendant toute la manoeuvre
grace à la rotation inverse de ses roues.The plate lifter remains stationary during the whole maneuver
thanks to the reverse rotation of its wheels.

Le cadre (17) est banalisé d'une couleur rouge, afin d'as
surer la sécurité lors de son utilisation. Aucune arrète tranchante
ne présente un danger pour l'utilisateur.The frame (17) is unmarked in a red color, so as
safety during use. No sharp edges
presents a danger to the user.

Dans une variante d'exécution de l'invention supprimant les cardans, et les remplaçant par un axe hexagonal, le cadre télescopique s'emboite de manière télescopique ce qui réduit son encombrement de moitié (les montants et l'axe hexagonal s'emboitent)  In an alternative embodiment of the invention eliminating the universal joints, and replacing them with a hexagonal axis, the telescopic frame fits telescopically which reduces its size by half (the uprights and the hexagonal axis fit together)
