Abstract
Locking device for securing cargo in containers or pallets, comprising two latches hinged together and hinged to the locking device frame, one by a fixed hinge pin and the other by a hinge pin which can move in translation. The latches are constantly acted on by a spring which draws them into the cargo locking position, in which the latches project up above the frame, by a spring and are changed over, by downwards pressure on the latches, to the cargo unlocking position, in which they are retracted.
Claims14
A locking device for securing cargo in a vehicle, comprising:
- a frame (7) comprising two first members (8) joined together by two second cross members (9) and capable of being fixed to the floor of the vehicle space intended to accommodate the cargo;
- a first latch (10) and a second latch (11) hinged together at one of their ends by a common transverse pivot pin (12), said first latch (10) having at its non-hinged end a transverse hinge pin (13) mounted in a fixed position between said first members (8), and said second latch (11) having at its non-hinged end a transverse hinge pin (14) guided in translation in longitudinal slideways (15) in said first members (8);
- means for changing said first and second latches (10, 11) from a cargo unlocking position, in which said latches are retracted down into said frame and said transverse hinge pins (13, 14) are separated to a cargo locking position, in which said first and second latches (10, 11) project above said frame (7) and said transverse hinge pins (13, 14) are brought near to each other;
- spring means for drawing said first and second latches (10, 11) from the cargo unlocking position to the cargo locking position;
- and
- first blocking means for blocking said first and second latches (10, 11) in the cargo unlocking position and second blocking means for blocking said first and second latches (10, 11) in the cargo locking position, respectively.

A locking device for securing cargo in a vehicle, comprising:
- a frame (7) comprising two bars (8) connected together by two terminal cross members (9), said frame (7) capable of being fixed to the floor of the vehicle which receives the cargo;
- a first latch (10) and a second latch (11) hinged together at one of their ends by a common transverse pivot pin (12), said first latch (10) having at its non-hinged end a transverse hinge pin (13) mounted in a fixed position between said bars (8) and said second latch (11) having at its non-hinged end a transverse hinge pin (14) guided in translation in longitudinal slideways (15) in said bars (8), whereby said common transverse pivot pin (12) of said first and second latches (10, 11) is at the apex of an essentially isosceles triangle, the two other angles of which are defined by said transverse hinge pin (13) of said first latch (10) and by said transverse hinge pin (14) of said second latch (11), whereby said first and second latches (10, 11) can be brought from a cargo unlocking position in which they are retracted downward into said frame (7) and in which said transverse hinge pins (13, 14) are separated, into a cargo locking position in which said first and second latches (10, 11) project upward on said frame (7) and in which said transverse hinge pins (13, 14) are close to one another;
- a first elastic means for drawing said first and second latches (10, 11) from the cargo unlocking position to the cargo locking position, and a second elastic means;
- a first blocking means for blocking said first and second latches (10, 11) in cargo unlocking position against the drawing force of said first elastic means;
- a second blocking means for blocking said first and second latches (10, 11) in a cargo locking position, whereby said second blocking means is pivotably mounted on said transverse hinge pin (14) of said second latch (11) and is adapted so that, under the action of said second elastic means, said second blocking means cooperates in a hook-like manner with said transverse hinge pin of said first latch (10) in order to prevent said first and second hinge pins (13, 14) of said first and second latches (10, 11) from separating from one another;
- and
- a blocking releasing means for releasing the effect of said first and second latches (10, 11) in the cargo locking position, whereby said blocking releasing means is mounted on said first and second latches (10, 11) in such a way that in the cargo locking position an operating surface of said blocking releasing means is located above said common transverse pivot pin (12) of said first and second latches (10, 11) whereby said blocking releasing means is constructed in such a way that when foot pressure is applied to said operating surface of said blocking releasing means it causes said second blocking means to pivot against the action of said second elastic means in order to release said second blocking means from said transverse hinge pin (13) of said first latch (10) in such a fashion that under the action of the foot pressure applied, said first and second latches (10, 11) can be brought into unlocking position and can be blocked in this position by said first blocking means against the action of said first elastic means.
