Case equipped with a one-piece clasp

Claim 2

Case composed of two parts articulated to one another, a first part of which has an opening for receiving a one-piece clasp comprising a body which is slidably mounted in the said opening and constructed so that it can be introduced into the said first case part by sliding through the said opening and on which are provided elastic return means for urging the body elastically counter to the direction in which the first case part is introduced, means, accessible from outside, for actuation through the said opening, for displacing the body by manual pressure counter to the said return means, locking means for keeping the case closed and retention means for cooperating, at the end of the mounting of the body in the first case part, by snapping in, with stop means provided on the said first case part so as to enable the said locking means to cooperate, in this position, with hooking means on the second part of the case, said body having an extension, the return means being formed in the extension of the said body in the direction in which the body is introduced into the first case part, so as to cooperate, by elastic bending, with a bearing surface provided on the said first case part, characterised in that the clasp body (7) has the general shape of a U, in that the said elastic return means consist of two branches (14) each formed in the extension of one of the two wings of the U-shaped body (7), in that the said retention means are lateral catches (15) projecting laterally from the said wings (9) of the U-shaped body (7) at the root of the said branches, and in that the said stop means (19) consist of the opposite interior lateral edges of the said opening (4) in the first case part (3).

Claim 3

Case composed of two parts articulated to one another, a first part of which has an opening for receiving a one-piece clasp comprising a body which is slidably mounted in the said opening on which are provided elastic return means for urging the body elastically counter to the direction in which the first case part is introduced, means, accessible from outside, for actuation through the said opening, for displacing the body by manual pressure counter to the said return means, locking means for keeping the case closed and retention means for cooperating, at the end of the mounting of the body in the first case part, by snapping in, with stop means provided on the said first case part so as to enable the said locking means to cooperate, in this position with hooking means on the second part of the case, said body having an extension, the return means being formed in the extension of the said body in the direction in which the body is introduced into the first case part, so as to cooperate, by elastic bending, with a bearing surface provided on the said first case part, characterised in that the said elastic return means (41) and the said retention means (40) are formed on a part (38) offset downwards relative to the lower edge of the clasp body (31) and connected to the latter with the possibility of elastic pivoting in the vertical plane so as to be able to engage elastically, upon introduction of the clasp into the first case part (33), in a hollow (42) made in the first case part (33) so that, in the direction in which the clasp is introduced into the first case part, the front flank of the said hollow (42) constitutes the stop means for the said retention means (40) and the rear flank of the said hollow (42) constitutes the bearing means for the said elastic return means (41).

Claim 4

Case composed of two parts articulated to one another, a first part of which has an opening for receiving a one-piece clasp comprising a body which is slidably mounted in the said opening on which are provided elastic return means for urging the body elastically counter to the direction in which the first case part is introduced, means, accessible from outside, for actuation through the said opening, for displacing the body by manual pressure counter to the said return means, locking means for keeping the case closed and retention means for cooperating, at the end of the mounting of the body in the first case part, by snapping in, with stop means provided on the said first case part so as to enable the said locking means to cooperate, in this position with hooking means on the second part of the case, said body having an extension, the return means being formed in the extension of the said body in the direction in which the body is introduced into the first case part, so as to cooperate, by elastic bending, with a bearing surface provided on the said first case part, characterised in that the said elastic return means (41) and the said retention means (40) are formed on a part (38) offset downwards relative to the lower edge of the clasp body (31) and connected to the latter with the possibility of elastic pivoting in the vertical plane so as to be able to engage elastically, upon introduction of the clasp into the first case part (33), in a hollow (42) made in the first case part (33) so that, in the direction in which the clasp is introduced into the first case part, the front flank of the said hollow (42) constitutes the stop means for the said retention means (40) and the rear flank of the said hollow (42) constitutes the bearing means for the said elastic return means (41).

Claim 5

Case according to claim 2, characterised in that the elastic return means (41) have the form of an elastically deformable closed loop.

Claim 6

Case according to claim 3, characterised in that the said loop has the form of a diamond.

Claim 7

Case according to claim 2, characterised in that the clasp has a weakened region, serving as pivot axis, at the location of the junction of the said pivoting part (38) with the clasp body (31).
