Abstract
The manual securing device includes a frame (1) supporting a guide rail (2), on which is mounted slidably a support head (3) receiving a chock (4) that can occupy a retracted position and a locked position away from the retracted position. This device is characterized in that the rail (2) has a series of holes (20) the head has a guide sheath (30) slidably engaged on the guide rail (2), the sheath (30) has at least one radial through-hole (31) designed to line up axially with one of the holes (20) of the guide rail (2) by sliding the head (3), and the head (3) has at least one locking pin (32) designed to be engaged in the alignment of holes (20, 31) formed, so that it can be immobilized in translation along the guide rail (2).
Claims17
1/ Manual securing device, comprising a frame (1) forming a surface bearing on the ground, supporting above and away from this surface a horizontal rectilinear guide rail (2), on which is mounted slidably a support head (3) equipped with a chock (4) that can occupy a retracted position and a locked position away from the retracted position, characterized in that the rail (2) has a series of vertical cylindrical holes (20) regularly spaced along the horizontal sliding axis of the head (3), said head has a guide sheath (30) slidably engaged on the guide rail (2), said sheath (30) has at least one radial through-hole (31) designed to line up axially with one of the holes (20) of the guide rail (2) by sliding the head (3), and the head (3) has at least one movable locking pin (32) designed to be engaged in the alignment of holes (20, 31) formed, so that it can be immobilized in translation along the guide rail (2).
2/ Device according to claim 1, characterized in that the pin (32) is carried by an actuating lever (33) articulated to the head (3), above the guide rail (2).
3/ Device according to claim 2, characterized in that the locking pin (32) forms a protrusion under the lever (33).
4/ Device according to claim 1, characterized in that the head (3) has two locking pins (32) and the guide sheath (30) has two through-holes (31), separated from each other, designed to receive the two locking pins (32).
5/ Device according to claim 1, characterized in that the or each locking pin (32) is borne by the chock (4) and is engaged, in the locked position of the chock, in a hole of the sheath (30) and in a hole (20) of the rail (2).
6/ Device according to claim 1, characterized in that the chock (4) is formed of a horizontal rigid rod, slidably engaged in a second sheath (35) borne by the head (3) above the first sheath, the chock (4) and this second sheath (35) extending in a transverse direction with respect to that of the guide rail (2), and said chock (4) being able to take a retracted position, according to which it extends from one side of the guide rail, and a locked position, according to which it extends, by an active portion (40), from the other side of the guide rail, said active portion (40) being designed to come into contact with the tread surface of the corresponding wheel of the vehicle to be immobilized.
7/ Device according to claim 1, characterized in that the horizontal rail (2) has a circular straight cross-section and the head (3) is equipped with means of immobilization in rotation, these means being separate from the guide rail (2).
8/ Device according to claim 7, characterized in that one of the means of immobilizing the head (3) in rotation comprises a brace (36) fixed to the head (3) away from the longitudinal geometrical axis of the sheath (30), and a slider plate (11) borne by the frame, extending parallel to the guide rail (2), on which the brace (36) bears slidably by its lower extremity.
9/ Device according to claim 7, characterized in that the other means of immobilization in rotation comprises a first elongated stop (12) fixed to the frame (1) and extending parallel to the guide rail (2), and a second stop (38), fixed to the first sheath (30), this second stop (38) bearing slidably against the first stop (12).
10/ Device according to claim 1, characterized in that the chock (4) and the sheath (30) have an indexing means consisting of a spur (42) forming a radial protrusion on the cylindrical surface of the chock (4) and a notch (35a) made in the extremity of the sheath (30), designed to receive the spur (42) when the chock (4) is in the locked position.
11/ Device according to claim 2, characterized in that it has a means of detecting the locked position of the chock (4) and of detecting the locking position of the or each locking pin.
12/ Device according to claim 11 taken together, characterized in that the detection means consist of a first detection element fixed to a handle (41) that the chock (4) possesses, and a second detection element fixed to the actuating lever (33), the two detection elements coming opposite each other when the chock (4) is in the locked position and the or each locking pin is in the locking position in the corresponding hole(s) (20) of the guide rail.
13/ Device according to claim 1, characterized in that the head (3) is equipped with at least one additional locking pin (39) fixed to an electric actuator (39a), and the second sheath (35) and the chock (4) each have a radial hole, and in the locked position of the chock (4), the radial hole borne by the chock is located in the axial alignment of the radial hole borne by the second sheath (35), such that, by activating the actuator (39a), the locking pin (39) is brought into the alignment of holes thus formed and, in this locking position, maintains the chock (4) in the locked position.
14/ Loading dock installation, characterized in that it is equipped with a device according to claim 13.
15/ Installation according to claim 14, comprising a dock with a means of access that can occupy a first position, allowing goods to be transferred between a warehouse and the transport vehicle, and a second position, not allowing this transfer, characterized in that it comprises a control unit, able to activate the actuator (39a) in the locking direction of the pin (39), based on information delivered by a position detector associated to the access means, so as to prohibit the unlocking of the pin (39) while said access means is in its first position.
16/ Device according to claim 8, characterized in that the other means of immobilization in rotation comprises a first elongated stop (12) fixed to the frame (1) and extending parallel to the guide rail (2), and a second stop (38), fixed to the first sheath (30), this second stop (38) bearing slidably against the first stop (12).
17/ Device according to claim 1, characterized in that it has a means of detecting the locked position of the chock (4) and of detecting the locking position of the or each locking pin.
