Description

The invention relates to an arrangement for stopping a door opening and closing a space such as the loading space of a vehicle, in its open position, of the type described in the preamble of claim 1 .

The document FR 2 496 746 already describes an arrangement for stopping a door opening and closing a space, in its open position, which comprises a fixed base part mounted on the support structure of the door and an assembly comprising a lever stop and an actuating handle for pivoting the lever, of the type described in the preamble of claim 1.

The invention aims to provide a simpler and more compact arrangement.

To achieve this object, the arrangement according to the invention includes the characteristics which are set out in the characterizing part of claim 1.

Other features of the invention are indicated in dependent claims.

The door stop arrangement according to the invention, generally designated by the reference 1, is intended in particular, but not exclusively, to equip the bodies of transport cars, as schematically indicates the figures 3 and 4 on which references 3, 4 and 5 respectively designate the vehicle body, the door and the bolt of the lever.

As can be seen from the figures, the door stop arrangement 1 essentially comprises a fixed base part 10 adapted, in the example shown, to be fixed under the body 3 of the vehicle, a stop lever 14 which is mounted on the fixed part 10, pivoting about an axis 12 between the rest position withdrawn under the body and its door stop position, that is to say locking the door 4 in its open position , in accordance with the figure 4 , as well as an actuating handle 16 of the lever.

The arrangement 1 is essentially characterized by the fact that the stop lever 14 is pivotally mounted around the axis 12 of the fixing base 10 between its rest and stop positions, against spring means recall 18, that the handle 16 comprises a hook-shaped element 20 by which it is lockable on the fixed base 10 by engaging behind a spout 22 of the base when the lever is in its stopped position, and that for this purpose the handle 16 is held on the lever 14 so as to be integral in rotation with the latter in the direction F1 of pivoting towards the stop position of the door, then is capable of pivoting on the lever, about an axis 24, against a return spring 26 to ensure the engagement of the hook 20 behind the spout 22.

To unlock the handle and thus allow the lever to return to its rest position of the figure 1 , the handle must be pushed so that it makes a slight pivoting movement in the direction of arrow F2, so that the hook can be released from the spout. Then the assembly formed by the handle and the lever is returned to the rest position by the compression spring 18.

The structure of the door stop arrangement 1, as illustrated in the figures, will be described below in detail, knowing that this is only an example of implementation of the invention without limitation.

With particular reference to the figure 9 we see that in the illustrated example of implementation of the invention, the stop lever 14 consists of two side cheek pieces 14a, 14b and a central piece 14c sandwiched between the cheeks 14a, 14b . More specifically, each cheek has the general shape of a T mounted pivoting on the fixed base 10 around an axis 12a, 12b by the free end of its leg 30, while the central piece 14c is mounted between the two 33 branches of the cheeks. The central part 14c comprises a fixing part 35 by which it is mounted between the branch parts 33 of the cheeks, so as to be adjustable in position in the axial direction of the latter as is apparent from the figure 4 and, at the end of the part 35, a head part 36 adapted to come to bear, in the door stop position, against the bolt of the bolt 5, as seen on the figure 4 . The return spring means 18 of the lever in its rest position are formed by two compression springs 18a, 18b, each associated with a cheek 14a, 14b. Each spring is mounted in a circular housing 39 and bears at one end on an abutment face 41 secured to the base and an abutment surface 40 secured to the cheek ( figure 8 ). As shown in particular by the comparison of figures 6 and 8 , the pivoting of the lever 14 towards its door stop position causes the springs 18a, 18b to be compressed in their circular housing 39.

The figure 9 also shows that the fixing base 10 has a sole-shaped part 43 and a perpendicular projecting part 44 which carries at its free end the spout 22 for locking the handle 16.

This handle 16 comprises a part 45 for pivotally actuating the lever 14 and a part 46 which ends in the locking hook. The handle comprises a third support part 47 by which it is mounted on the lever 14, precisely on the two cheeks, with interposition of the return spring 26 between the handle and the cheeks 14a, 14b which each engages by a pin 24a , 24b in a bearing element 50 of the handle. Each cheek is further provided with a projecting element 52a, 52b on which one end of the spring 26 bears, the central part of which is supported by the bearing 50.

The operation of the door stop arrangement according to the invention is already apparent from the foregoing description. To stop the door 4 in its open position, the lever 14 is pivoted from its rest position of the figure 3 , using the handle 16, in its door stop position of the figure 4 . In this door stop position, the lever abuts by its head portion 36 against the door bolt 5 of the door. The lever is locked in this position by locking the handle 16 on the fixed base 10 through the engagement of the hook 20 behind the spout 22. More precisely, by pulling the handle 16 in the direction of the arrow F1, the pivoting of the stop lever 14 in the same direction, the rounded profile of the handle at the hook 20 sliding along the rounded profile of the spout 22 of the base, as shown in the figure 10B . When the hook passes over the spout and the handle is released, the hook engages behind the spout under the effect of torsion spring 26 which rotates for this purpose the handle around the axis 24 relative to the lever 14.

To release the door, the handle 16 is unlocked from the fixed base by pushing the handle 16 in the direction of arrow F2 until the hook is released from the spout, which allows the lever to return, with the handle, to its rest position under the effect of the compression spring 18.

As was specified above, the structure of the arrangement as shown in the figures has been given only by way of example and the essential parts, namely the fixed base 10, the lever 14 and the handle 16 can be produced in any other way, provided that the functions of these parts, which have just been mentioned, are respected.
