Abstract
A castor includes a body, a wall of a rotary bearing, a wheel including an orifice, a rotary shaft, elements for mounting the shaft to co-operate with the bearing wall, the latter having a first bearing wall portion of tuning-fork-shape defining a slot between two limbs and another bearing wall portion having a base and a tenon secured to the base, the tenon may be engaged in the slot. The elements include two oblong holes formed in the limbs and a third oblong hole formed in the tenon. The holes are arranged in the limbs, and in the tenon in such a manner that all three of them are centered on a first axis when the tenon is engaged in the slot. The shaft passes through the bearing wall so that its axis is substantially parallel to the first axis and can be engaged in the orifice in the wheel.
Claims11
A castor for furniture or the like, the castor comprising:
- a body;
- means for connecting said body to furniture;
- a rotary bearing wall defined substantially in a first plane;
- means for securing the bearing wall to the body;
- at least one wheel including an orifice defined on a first axis;
- a rotary shaft of section complementary to the orifice, said rotary shaft defining a second axis;
- and
- means for mounting said rotary shaft in co-operation with said first bearing wall, said rotary shaft also being suitable for being engaged in said orifice in such a manner that the first and second axes coincide to enable the wheel to pivot about the second axis;
- wherein the bearing wall is constituted by:
- a first bearing wall portion, said first bearing wall portion being generally in the form of a tuning-fork defining a slot between two limbs secured to a slab defining the end of said slot, said two limbs being situated in planes that are substantially parallel to the first plane;
- a second bearing wall portion comprising a base and a tenon secured to said base, said tenon being of a shape that its substantially complementary, at least in part, to the slot so as to enable it to be engaged in said slot;
- means for uniting said first and second bearing wall portions when the tenon is engaged in the slot;
- said means for securing the bearing wall to the body being constituted by means for securing the first wall portion with said body;
- and
- said means for mounting said rotary shaft to co-operate with the bearing wall being constituted by:
- a first oblong hole made in the first limb and a second oblong hole in the second limb;
- and
- a third oblong hole made in said tenon;
- said first, second and third oblong holes being of cross-section substantially equal to the corresponding cross-section of said rotary shaft and of longitudinal section greater than the corresponding longitudinal section of said shaft, and being arranged respectively in the limbs and in the tenon in such a manner that when the tenon is engaged in the slot, they are centered on a third axis substantially perpendicular to the first plane, the rotary shaft thus being capable of passing right through the bearing wall so that the second axis is substantially parallel to the third axis and can have one of its ends engaged in the orifice of the wheel.
