Description

The present invention relates to the closing of swing doors of vehicles and more particularly of heavy vehicle doors as well as those of containers and similar objects which include cremone bolts preferably embedded and whose bolt-forming elements are engaged in strikes forming part of the fixed structure of the container vehicle or other elements.

The invention creates a new handle which has an integrated locking device comprising only a very small number of parts which can be easily produced by injection molding in plastic material, which makes it possible to manufacture both at a high quality. and a low cost since no machining operation is necessary and the assembly of the parts is, moreover, very simple.

The invention also creates a handle which can be dismantled so that it can optionally be changed or allows the change of all or part of the cremone bolt contrary to what is practiced in known devices.

Another considerable advantage of the invention resides in the fact that the operation of the integrated locking device is such that it cannot be damaged even if the operator performs false operations, for example when he closes or attempts to close. the door while the locking device has been previously returned to the locked position.

Yet another advantage of the invention resides in the fact that the handle with integrated locking device can be operated with one hand and brought, after rotation of the bolt rod, into a position for which the operator benefits from maximum force to take off the door, which is very important with regard to tight seal doors such as there are on refrigerated vehicles.

In accordance with the invention, the handle for a lever with an integrated locking device, in particular for a vehicle, said handle being wedged on the rod or axis of the lever, comprises a support crossed by the rod of the lever on which is fixed one end of a body which forms, at its opposite end, a handle and which supports an axis for at least one pawl associated with a spring holding this body in a hook of the support, a lever articulated to the body comprising means of unidirectional actuation of the pawl for the disengage from the hook by authorizing the pivoting of said body causing that of the cremone bolt in the direction of opening, said hook forming, on its top, a cam for actuating the pawl during the opposite pivoting of the body in the direction of the closing.

In the drawing, 1 designates a heavy-duty type road vehicle, the rear panel of which is closed by two doors 2, 3 hinged by hinges 4. The doors 2, 3 are each provided with a cremone bolt 5 whose bolts engage in keepers 6, 7. Each lever 5 is controlled by a handle 8. It is advantageous, as shown by the tearing of FIG. 1, that the cremone bolts are inserted into the thickness of the doors 2, 3 and that only the handles 8 which control them appear.

The handle comprises a support 9 having the shape of a bowl when the handle is embedded, this support being fixed by screws or rivets 10 to the external face of the door 2 or 3. The cremone bolt 5 crosses the lateral sides of the support 9 .

The handle comprises a body 11 made of molded material preferably of synthetic material which delimits, at one end, a handle 12 for its operation.

Opposite the handle 12, the body 11 forms a half-shell 13 in which it is advantageous that a gasket 14 is inserted during the molding of the body 11. The gasket 14 is advantageously metallic, for example steel stainless, and has a female thread 15.

The half-shell 13 with its lining 14 is used for centering the handle on the cremone bolt 5. Preferably, according to the invention, the cremone bolt consists of two rods 5a, 5b, one, for example the rod 5a, having one male socket, and the other, the rod 5b, a female socket, as shown in FIG. 4.

To immobilize the cremone bolt, the rods 5a, 5b have holes 16 (fig. 3), for example four in number, through which screws 17 have passed, the position of which is illustrated in FIGS. 2 and 3. Each screw 17 passes through a half-shell 18, for example of molded synthetic resin, then the hole 16 of one of the rods 5a, 5b of the cremone bolt and is screwed into the internal thread 15. In this way, the half-shell 18, the rods 5a, 5b and the body 11 are rigidly connected to each other.

Fig. 3 shows that the screws 17 occupy an inclined position for example at 45 ° relative to the bottom of the support 9 when the body 11 is in the closed position as illustrated in FIG. 3. In this position, the screw heads 17 are turned towards the bottom of the support 9 and are therefore inaccessible. On the other hand, when the body 11 is pivoted by driving the rods 5a, 5b of the cremone bolt, this pivoting taking place at an angle of approximately 90 °, then the heads of the screws 17 are accessible (fig. 6), which allows, if necessary, disassembly of the handle to make it possible to replace either this handle or one or the other of the rods 5a, 5b of the lever.

At a distance from its opposite end, the body 11 supports, below the handle 12, an axis 19 on which a lever with two branches 20 is articulated, one of the branches of which, that designated by 20a, forms a pusher 21 which is level with the upper edge 9a of the support 9.

The other branch 20b (fig. 3) of the lever 20 extends substantially at right angles to the branch 20a and is disposed on the path of a bolt 22 of a lock barrel 23 carried by a recessed part 24 of the body 1. The lock barrel 23 is intended to be controlled by means of a key, not shown.

The pin 19 supports on both sides of the lever with two branches 20 of the pawls 25, 26 of molded material with which are associated torsion springs 27, 28 tending to rotate them in the direction for which a projecting part 29 which 'they have (fig. 6) is engaged below hooks 30 formed by the bottom of the support 9 and whose top 30a is inclined to form a cam.

Fig. 4 shows that the springs 27, 28 wound on the axis 19 have one end 27a, respectively 28a, bearing under a bearing surface 11a respectively 11b of the body 11 and one end 27b respectively 28b engaged in a hole 31, 32 of the pawls 25, 26.

The pawls 25, 26 are retained by lateral stops 33, 34 formed on the sides of the branch 20a of the lever with two branches 20 and constituting unidirectional actuating means (FIGS. 4 and 6). The branch 20a is itself thus brought into abutment against a fallen edge 35 (FIGS. 3 and 4) of the part of the body 11 which covers the pawls 25, 26 as well as the lever with two branches 20, with the exception of the pusher 21.

The body 11 is shaped to delimit, between the hollowed-out part 24 and the half-shell 13, a housing 36 whose bottom 37 has a slot 38. A finger 39 formed from the bottom of the support 9 is passed through the slot 38 and has a buttonhole 40 intended for fitting a sealing plummet 41 (FIGS. 2 and 3).

The body 11 supports, between the housing 36 and the half-shell 13, an axis 42 for the articulation of a flap 43 covering the housing 36 and the recessed part 24 and, consequently, the lock barrel 23.

In addition to the above, the body 11 is connected to the support 9, by means of one or protrusions by springs 44 illustrated in FIGS. 2 and 6 in the form of tension springs. The springs 44 therefore tend to hold the body 11 so that it takes support in the bottom of the support 9 and that its top is thus at the same level as the external edge of the support.

In addition, the bottom of the support 9 has tabs 45, 46 pierced with buttonholes 47 for the establishment of a padlock 48, the stirrup 49 of which prevents pushing of the pusher 21, which constitutes an additional security element to those which are described in the foregoing and the operation of which is explained below.

Considering fig. 3, it can be seen that even after removing the padlock 48, it is not possible to lift the handle by the handle 12 when a sealing lead 41 is in place in the buttonhole 40 of the finger 39. Indeed, this lead of sealing which, most often comprises a strip of leaded steel, constitutes a retaining pin.

To remove the sealing lead or put it in place, it suffices to pivot the flap 43 about its axis 42, which gives access to the housing 36. Preferably, a return spring is associated with the flap 43 to keep it in closed position.

Assuming that the sealing lead is removed, it is no more possible to rotate the body 11. In fact, a force directed along the arrow f1 (fig. 6) does not allow the projecting part 29 to escape. pawls 25, 26 of the position they occupy below the hooks 30.

Furthermore, the depression of the pusher 21 and the pivoting of the lever with two branches 20 around the axis 19 are prevented by the bolt 22 of the lock barrel 23 since the second branch 20b of the lever abuts against said pawl.

After removal of the sealing lead 41, it is therefore necessary to maneuver the lock barrel 23 to pivot its bolt 22 and move it away from the branch 20b.

By exerting a push on the pusher 21, the lateral tabs 33, 34 then pivot the pawls 25, 26, the projecting part 29 of which escapes the hooks 30, which then allows the body 11 to pivot and, consequently, the drive in rotation of the rods 5a, 5b of the lever 5.

The foregoing movement is easily accomplished. In fact, the handle 12 can easily be grasped with a hand, a finger of which presses on the pusher 21. The handle 12 after pivoting of the body 11 makes it possible to exert a significant traction on the door because it can be well held in hand in a position for which the operator can develop significant force.

To ensure closing, the door is pivoted and the cremone bolt actuated by folding down the body 11.

The force of the tension springs 44 may be provided sufficient for the folding down of the body 11 to take place automatically. When the body 11 is brought back into the support 9, the pawls 25, 26 bear against the cam 30a of the hooks 30, which makes them pivot against the action of the springs 27, 28 which then bring their projecting parts 29 in engagement with said hooks 30.

It should be noted that this movement occurs even if the bolt 22 of the barrel 23 has been brought back to the closed position as illustrated in FIG. 4 since the pawls 27, 28 are arranged on either side of the lever with two branches 20. In this way, there is no risk of damage to the parts even in the event of sudden closure.

According to the development illustrated by figs. 9 to 13, the pusher 21 is mounted on an auxiliary axis 51 parallel to the axis 19 carrying the pawls 25, 26. The axis 19 is provided between the pawls with a planet carrier 52 of which it is integral in rotation and which has an axis 53 extending in a plane perpendicular to the axis 19.

The axis 53 is used for the articulation of a satellite disc 54 of which a finger 55 (fig. 13) is normally held in abutment against a fixed stop 56 by a spiral spring 57.

The satellite 54 is provided, on its top, with a stop 58 located on the path of the bolt 22 of the barrel 23. The satellite 54 has, in addition, a notch 59 and a lateral stop 60 which is located opposite the branch 20b of the pusher 21 when the finger 55 is in abutment against the stop 56.

In the unlocked position of the barrel 23, the lateral stop 60 of the satellite can be pushed by the branch 20b of the pusher 21, branch which is in the position illustrated in FIGS. 12 and 13. By depressing the pusher 21 to bring it into the position illustrated in dashed lines in FIG. 10, this has the effect of tilting the planet carrier which drives the axis 19 and which consequently releases the pawls 25, 26 from the hooks 30.

The loop 12 can therefore be actuated as described in the foregoing.

When it is desired that the handle is locked, the barrel 23 is turned by means of a key not shown, which rotates the bolt 22 in the direction of the arrow f₂ to bring it from the position illustrated in fig . 12 to that illustrated in FIG. 9.

In its movement, the bolt 22 comes into contact with the stop 58 of the satellite and causes it, therefore, to rotate around the axis 53, which has the effect that the notch 59 which this satellite presents is then opposite of branch 20b of pusher 21. Figs. 9 and 10 show that the pusher 21 can then be actuated from the position illustrated in solid lines to the position illustrated in phantom without producing any command, that is to say that this pusher is crazy around the axis who wears it.

The invention is not limited to the embodiment, shown and described in detail, because various modifications can be made without departing from its scope. In particular, the support 9 can protrude above the exterior face of the doors 2, 3 when the cremone bolts 5 are themselves disposed outside of said doors. In addition and as illustrated in the drawing, the relatively complex shape of the body 11 allows the formation on its underside of stiffening ribs 50, while the top can be smooth, which is particularly suitable for the production of said body 11 by molding. synthetic resin. The same is true of the support 9, the accessories of which it includes such as the tabs 45, the finger 39, the hooks 30 as well as other parts form reinforcements ensuring its rigidity.
