Abstract
A device for assembling two components (1,2) includes a lateral positioning set (3). The device includes a fixing screw (10), in particular threaded on the right, and capable of moving freely in a smooth through hole (13) provided in the first component (1), a spacer (20) bearing an external thread (23), in particular on the left, capable of co-operating with a tapped through hole (23), in particular on the left, provided on the second component (2) and an internal tapping (21), in particular on the right capable of co-operating with the fixing screw (10), the screw (10)/spacer (20) friction coefficient, directly or indirectly, being greater than the spacer (20)/tapped hole (23) friction coefficient, directly or indirectly.
Claims11
A device for assembling first and second parts exhibiting lateral positional play in a given direction, the device comprising the following that are all aligned in the given direction:
- a smooth through-hole in the first part;
- a fixing screw freely movable through said smooth through-hole and carrying a threading of a first type;
- a tapped through-hole of a second type on the second part opposite said smooth through-hole;
- and
- a spacer carrying an external threading of the second type able to interact with said tapped through-hole and an internal tapping of the first type able to interact with said fixing screw, a coefficient of friction between said fixing screw and said spacer being different from a coefficient of friction between said spacer and said tapped through-hole,
- said tapped through-hole and said spacer being linked by a frangible plastic tab.
A device for assembling first and second parts exhibiting lateral positional play in a given direction, the device comprising the following that are all aligned in the given direction:
- a smooth through-hole in the first part;
- a fixing screw freely movable through said smooth through-hole and carrying a threading of a first type;
- a tapped through-hole of a second type on the second part opposite said smooth through-hole;
- and
- a spacer carrying an external threading of the second type able to interact with said tapped through-hole and an internal tapping of the first type able to interact with said fixing screw, a coefficient of friction between said fixing screw and said spacer being different from a coefficient of friction between said spacer and said tapped through-hole,
- wherein said spacer includes a restraint that increases the coefficient of friction between said fixing screw and said spacer, and
- wherein said restraint is a friction ring concentric with said spacer.

- a smooth through-hole in the first part;
- a fixing screw freely movable through said smooth through-hole and carrying a threading of a first type;
- a tapped through-hole of a second type on the second part opposite said smooth through-hole;
- and
- a spacer carrying an external threading of the second type able to interact with said tapped through-hole, and an internal tapping of the first type able to interact with said fixing screw, a coefficient of friction between said fixing screw and said spacer being different from a coefficient of friction between said spacer and said tapped through-hole,
- wherein said spacer includes a radial hole for blocking in rotation.
