Description

The present invention relates to a gallery locking device

  luggage racks and support accessories on roofs of motor vehicles, arranged at the end of a cross-member having in cross section a square hollow profile and which is fixed by support feet to the roof of the vehicle, for example to the gutter or to a surrounding of the roof, a device which consists

  by a lock case containing a cylinder lock

  dre and which engages in the hollow profile,

  The object of the invention is to arrange a provision

  locking device of this type, regardless of the configuration of the support leg attached to the cross member, so that it can perform several functions

of security.

  To this end, according to the invention, the lock housing is arranged in such a way that in the position of

  closure, not only does it cover up making it inac-

  transferable the fixing of the support foot to the roof of the vehicle,

  but still it protects available support accessories

  placed on the crosspiece against removal or opening.

  Thanks to the invention, it is possible to avoid having to

  take special security measures for access

  support evenings or for the fixing point of the support foot on the vehicle roof A crossmember provided with the locking device according to the invention can be

  mass produced, so that when it is adapted

  tation to specific models of the vehicle roof, it suffices to fix on it other support feet and the desired support accessories, without this adversely affecting the

security measures.

  According to an advantageous realization of the main-

  cipe of the invention, the lock housing, with its

  cylinder rure, may have, in addition to the closed position, a first open position provided by

  a snap-fastening and, in addition, a second open position

  -2- ture ensured by an end stop and in which

  the fixing point of the support leg on the roof of the vehicle

  hicule, for example a clamping screw, is accessible.

  The locking device therefore comprises three positions

  tions, which can be used in a logical sequence. In the first position, or closed position, as long

  support accessories such as fixing the foot

  then on the roof of the vehicle are protected In the two

  xth position, or first opening position, ensured by a snap, the fixing of the support foot on the vehicle roof remains protected but the support accessories mounted on the crossmember can be opened or removed In the third position, or second position

  opening, access to the attachment point of the foot

  then on the roof of the vehicle also becomes free.

  Advantageously, the lock housing can be provided with a spring element in the form of a ribbon, which projects from one side of the lock housing, is engaged in song in the hollow profile of the cross member and present, to ensure the latching in the first opening position of the lock housing, a spring catch cooperating with a rivet arranged in the cross member and,

  for determining the second open position

  ture, a guide part filling the hollow profile and playing the role of end stop cooperating with the rivet.

  The lock housing, together with the

  spring element and its guide part, can advantageously

  suitably be in one piece of plastic, so that in particular if the crosspiece is made of metal

  light, a considerable weight saving is obtained.

  In the case of a cross member, which presents

  above the hollow square profile a T-shaped groove for the mechanical fixing of support accessories, the lock housing can advantageously be provided with a -3 insert covering this T-shaped recess This insert can, according to a Another embodiment of the object of the invention, be provided with a pin engaging in the T-shaped groove and, to ensure mechanical locking, in a recess.

  dement corresponding to "the support accessory.

  To make possible an easy manipulation of the locking device, it is possible to provide on the lock housing, opposite gripping cavities

between them.

  For the bolt of the cylinder lock, an internal stop projection can be arranged on the

lower side of the sleeper.

  The invention will be better understood on reading

  of the following detailed description and examination of

  attached drawings, which represent, by way of example

  non-limiting, an embodiment On the other hand,

  very features and advantages of the invention remain-

  will emerge from the description and the drawings.

  Figure 6 is a long sectional view

  dinal corresponding to Figure 1, with a tenon on

  the lock case, a pin that engages in the access-

  support evening ensuring its mechanical fixing.

  As shown in Figure 1, for fixing support accessories, for example

  ski racks, etc. on the roof of a motor vehicle

  bile, a cross member 1 is provided, which is supported on each side by a support leg 2 in the gutter of the vehicle roof and which is blocked by a screw

  tightening 3 The crosspiece 1 is made of light metal It pre-

  feel, as can be seen in particular on the Fi-

  gure 2, a square hollow profile 4 and, above it

  ci, a T-shaped groove, 5 The support leg 2 is fixed by rivets 6,7 to the lower side of the cross-member 1 In the T-shaped groove, 5, is inserted by a corresponding profile, an accessory support 8 To protect the fixing of the clamping screw 3 on the support foot 2, a locking device is provided

  consisting of a lock housing 9 made of plas-

  tick and by a pump or cylinder lock 10 fixed to this case The lock housing 9 forms, as can be clearly seen in particular in FIG. 3, a part comprising a spring element 11 in the form of a ribbon or strip engaged in the hollow profile 4 of the cross-member 1, part which projects on one of the sides of the lock housing 9, is arranged in edge in the hollow profile 4 and has at its free end a guide part

  12 filling the latter The spring element 11 pre-

  feels, substantially in the middle of its length, a spring notch 13 disposed in the vicinity of the rivet 6 making

  protrusion inside the hollow profile.

  In the position of the lock housing 9 re-

  shown in Figures 1 and 3, when the bolt 14 of

  the pump lock 10 engages behind a protruding

  -5- 15 provided on the lower side of the cross member 1, the fixing of the support leg 2 on the vehicle roof is protected, because the lock housing 9 is

  engaged by a recess 16 above the clamping screw

  rage 3 and covers it, while the support accessory 8 is also protected in the groove 5, due to the fact that an insert 17 is applied at the top

  of the lock boot 9 in front of said support accessory

port 8.

  If it is necessary to open, remove or replace the support accessory 8, we unlock

  -the cylinder lock 10 and, by acting on the cavi-

  gripping tees 18, pull the lock case 9

  outside the hollow profile 4 of the cross member 1 on a dis-

  sufficient strength for the spring notch 13 of the

  spring element 11 snaps onto the rivet 6 If it is then necessary to remove the crossmember 1 from the roof of the

  vehicle, pull the lock case 9 even further

  tage out of the hollow profile 4, until the guide part 12 presses against the rivet 6 In this

  position visible in Figure 5, the service boot

  rure is pushed laterally by the spring element 11, so that the clamping screw becomes accessible

for the application of a tool.

  The fixing of a crosspiece with feet

  then the insertion of a support accessory and the pro-

  tection of the fixing of the support feet on the roof

  of the vehicle and the support accessory in the

  nure 5 take place in the reverse sequence.

  The example in Figure 6 shows

  feels a cross member 1 to which is attached a foot

  pui 2 in turn intended to be fixed to an entourage of

  roof 19 Here too, the clamping screw 3 is covered

  green by the lock case 9 To provide additional security for the support accessory 8, -6- the lock case 9 is provided with a pin 20, which engages in a corresponding recess in 21 of said support accessory For the rest, the functional arrangement of the locking device of Figure 6 corresponds to that of the device of Figure 1. -7-
