Definitions
- the present invention relates to a device for move a load high, including a load carrier intended to receive the load, a drive member without end passing on upper and lower return members and comprising two strands extending between these organs of return, an appropriate connecting member connecting one of the strands of the drive member to the load carrier, a driving member to rotate one of the return members in order to move the load carrier in height, and means for guide the load carrier during its movement.
- Devices of this type which are generally consisting of elevators and hoists, include appropriate security measures to prevent the load carrier falls in free fall during a break accidental drive organ.
- the present invention proposes to remedy these disadvantages and to do this it has as its object a device for moving a load vertically, having the constitution indicated in the first paragraph above and characterized in that the drive member is housed, at less along its strand which is connected to the load carrier, in a corridor with a longitudinal slot providing passage to the liaison body and along which it is movable during the height movement of the load carrier, and that there is limited clearance between the lane and the drive so that in case of rupture accidental, it cannot sag to the game lower of the corridor under the action of the weight of the load carrier.
- the corridor thus constitutes a very simple to prevent the load carrier from falling free.
- the corridor receives the drive member over its entire length.
- the longitudinal slot forms a closed loop formed in the walls of the corridor that face each other.
- the drive member is a toothed belt while the return members are toothed wheels.
- the corridor has an internal section slightly larger than that of the organ so that it can move longitudinally in said corridor without being able to fold in accordion in case of breakage.
- the device shown in Figure 1 is a elevator, but it stands to reason that it could be constituted by a hoist arranged vertically or obliquely without as far as this goes beyond the scope of the present invention.
- the elevator visible in Figure 1 includes a cabin 1, a toothed belt 2 passing over a toothed wheel upper 3 and on a lower gear 4, a member link 5 connecting one of the strands of the belt 2 to the cabin 1, a conventional driving member 6 intended for drive the upper gear 3 in rotation, and conventional means 7 for guiding the cabin 1 when the toothed belt 2 circulates under the control of the organ motor 6.
- the driving member 6 includes an electric motor 8 and a reduction gear 9 mounted between the motor and the gear wheel 3. It goes without saying, however, that the electric motor 8 could be replaced by a motor hydraulic or pneumatic.
- gear wheels 3 and 4 are identical, which is however not compulsory.
- the belt notched 2 is housed over its entire length in a corridor 10 forming a closed loop and whose facing walls two by two are provided with a longitudinal slot 11 also forming a closed loop.
- the connecting member 5 connecting the cabin 1 to one of the strands of the toothed belt 2 crosses the straight section corresponding to the longitudinal slot 11.
- Corridor 10 has a cross section internally slightly larger than that of the toothed belt so that it can circulate easily during actuation of the drive member, but cannot fold accordion if broken.
- the dimensions of the corridor cross sections and of the toothed belt are chosen so as to prevent following an accidental rupture, it collapses at the lower part of the corridor under the weight of the cabin and its content.
- the toothed belt breaks accidentally slightly above the organ of link 5 during the cabin climb, the part lower part of the broken strand (which is located under the organ of bond 5) would compress in the corresponding part of the corridor under the weight of the cabin without being able to circulate and would therefore prevent the latter from falling free.
- the driving member 6 could not advance the upper part of the broken strand (which is located above the connecting member 5) in the part corridor and would stop automatically under the excessive effort exerted on him.
- the toothed belt could possibly be replaced by a passing chain on two gears shaped to allow its training.
- a corridor whose section would be adapted to that of the chain so that in the event of accidental breakage it will be blocked under the weight of the load carrier.

Claims (5)
- Dispositif pour déplacer une charge en hauteur, comprenant un porte-charge (1) destiné à recevoir la charge, un organe d'entraínement sans fin (2) passant sur des organes de renvoi supérieur (3) et inférieur (4) et comportant deux brins s'étendant entre ces organes de renvoi, un organe de liaison approprié (5) reliant l'un des brins de l'organe d'entraínement au porte-charge, un organe moteur (6) pour faire tourner l'un des organes de renvoi afin de déplacer le porte-charge en hauteur, et des moyens (7) pour guider le porte-charge pendant son déplacement, caractérisé en ce que l'organe d'entraínement (2) est logé, au moins le long de son brin qui est relié au porte-charge (1), dans un couloir (10) comportant une fente longitudinale (11) livrant passage à l'organe de liaison (5) et le long de laquelle celui-ci est déplaçable pendant le déplacement en hauteur du porte-charge (1), et en ce qu'un jeu limité est prévu entre le couloir (10) et l'organe d'entraínement (2) afin qu'en cas de rupture accidentelle, celui-ci ne puisse pas s'affaisser à la partie inférieure du couloir sous l'action du poids du porte-charge.
- Dispositif selon la revendication 1, caractérisé en ce que le couloir (10) reçoit l'organe d'entraínement (2) sur toute sa longueur.
- Dispositif selon la revendication 2, caractérisé en ce que la fente longitudinale (11) forme une boucle fermée ménagée dans les parois du couloir (10) qui se font face.
- Dispositif selon l'une quelconque des revendications précédentes, caractérisé en ce que l'organe d'entraínement (2) est une courroie crantée tandis que les organes de renvoi (3,4) sont des roues dentées.
- Dispositif selon la revendication 4, caractérisé en ce que le couloir (10) a intérieurement une section transversale légèrement plus grande que celle de l'organe d'entraínement (2) afin que celui-ci puisse se déplacer longitudinalement dans ledit couloir sans pouvoir se plier en accordéon en cas de rupture.
