Abstract
A device for the connection and the locking of two parts (30a, 30b), including a female part (10) comprising two bars (12), a male part (21) cooperating with this female part (10), and a hinged flap (17). Each bar (12) contains two balls (2a, 2b) and at least one movable inner stop (5) arranged between the balls (2a, 2b). The axial length of the movable stop (5) plus the diameters of the two balls (2a, 2b) is greater than the distance between the two lateral faces of the branch (11a, 11b) in which the ball bar (12) is situated. Also provided is a method for the connection and the locking of two parts, a ball bar, and a method for producing the latter and to the uses thereof.
Claims17
A device for the connection and the locking of two parts, comprising:
- a U-shaped female part provided with a bar on each branch of the U-shaped female part;
- a male part comprising an end capable of being inserted into an opening of the female part and of cooperating with the two bars of the female part;
- a hinged flap capable of cooperating with each bar;
- the hinged flap being mounted on the female part or the male part;
- wherein each bar contains
- two balls each arranged at a respective end thereof;
- at least one movable inner stop arranged between the balls;
- the axial length of the movable stop plus the diameters of the two balls being greater than the distance between two lateral faces of the branches in which the bar is situated.
A ball bar comprising:
- a hollow part of elongate shape, the longitudinal ends of said elongate shape being drawn in;
- two balls arranged inside the hollow part of elongate shape, at each of its longitudinal ends;
- and
- at least one movable inner stop arranged inside the hollow part of elongate shape, between the balls,
- wherein the axial length of the movable inner stop is chosen such that when one of the balls is fully retracted into the hollow part of elongate shape, it is impossible for the other ball to retract fully into the ball bar.
