Description

PLASTIC RAISED ROOF FOR VEHICLE A

BODYWORK IN SHEET.

  The present invention relates to a roof

  plastic tee fitting a vehicle with sheet metal bodywork and comprising a windshield support, two front doors, a loading platform located behind the two front seats, as well as a roll bar which, interposed between said support -brise and said loading platform, connects the two parts of the sheet metal body which receive the front doors. This roof includes a projection located above the front seats and a rear part located behind

said seats.

  Roof inserts known so far are most often used to replace a tarpaulin

  for all-terrain vehicles. Therefore, they consis-

  try only in a rear part covering the cabin, or in a forward and a rear part. In the

  type of realization of an usual qualified roof insert-

  Lement of roof with rigid top (type "hard top") and comprising a projection as well as a rear part, these two parts are most often assembled by conformation and constitute a single whole. Or the fact that these vehicles very often have side doors in the seat area

  before, the projection of the roof forms a free projecting

  lie forward beyond the rear. By

  therefore, the attached roof has a relative volume-

  tall, it's hard to handle as well when

  of its installation on the vehicle only when it is dismantled

  floor and it requires a large space for its storage.

  In addition, there is a permanent fear that the part of the roof projecting freely towards the front will be damaged during storage, i.e. when the roof is not

not used.

  The present invention therefore aims to provide an attached roof which, on the one hand, is easy to handle during assembly and which, on the other

  share, requires as few modifications as possible

  tees to a production vehicle designed to receive a tarpaulin. According to the essential characteristics of the roof

  of the invention, its projection and its rear part

  kill elements - separate, these two elements can be connected independently of each other to the vehicle by

fixing means.

  Thus, each separate element can be attached individually to the vehicle. Thanks to the smaller dimensions of the two elements, they are also significantly easier to handle and they can be attached individually. A surprising effect, which can be obtained with this embodiment or this arrangement separate from the projection and the rear part, lies in the fact that said projection can be mounted or moved independently of the rear part and that selective use of these two elements independently of each other is possible. Thus, the ventilation in the region of the two front seats of the vehicle can be influenced by

  the roof advancement. Universal use possibilities

  hard-top type roof saddles are also

  controlled by the configuration of the independent rear part

  dante of the advance, since said rear part can be made as a rear wall located behind the front seats, or as a covering

  of the entire loading platform.

  In another type of embodiment according to the invention

  tion, the roof projection extends from the barrier support

  breaks up to the roll bar area and the rear part extends from said roll bar to the end

  the loading platform away from the front seats.

  Because the roll bar is used as a support piece for the two parts of the attached roof, it is possible to obtain an impeccable fit and a

  waterproof connection between the roof parts and the vehicle.

  At the same time, increased protection is maintained against the risk of injury resulting from an accident when the vehicle is capsizing, thanks to the incorporation of the roll bar in the attached roof. In another type of embodiment according to the invention, the rear part of the roof engages over

  with the roll bar in the direction of the front seats.

  Thanks to this overlap by the rear part of the roof, an impeccable sealing and anchoring of the latter is possible even at high travel speeds. In another advantageous embodiment,

  the roof overhang covers the roll bar in di-

  loading platform and it is applied

  preferably on the front end of the rear part of the roof. This results in centering and

precise support for said advance.

  It is also possible to adapt the transition zones of the overhang and the rear part of the roof to the shape of the roll bar. and to insert

  sealing elements between one of the transition zones

  tion and said arch, and / or between the transition zone of the roof overhang and the transition zone of its rear part. These seals, combined

  available for collection, ensure not only-

  impeccable airtightness preventing water from entering, but also protection against

  phenomena of traction and noise, said linings

  tures serving in addition to elastic supports of the individual parts of the roof between them or with the roll bar, which prevents shocks of these members on the body. In a particularly advantageous type of embodiment, the rear part of the roof extends between the rear face of the front seats and the end of the loading platform facing said seats, O255 and it is provided with a transition zone which covers

  the roll bar in the direction of said front seats.

  Since this rear part is now separated from the roof overhang, it is possible without great difficulty to obtain a closed or open loading platform each time, as in a construction set, by using the roof overhang combined with different rear parts of this roof. This possibility of variation allows a double use

  of the roof overhang and therefore easier storage

  the parts of the roof considered that are not used

sées.

  According to the invention, it is also possible to

  ble de munir.l'vancée roof hooks which, to form a pivoting support of said projection, are in

  plug with retainer stops

  breeze and which, in an extreme region oriented towards the roll bar, are movable relative to the latter, perpendicular to the floor of the vehicle, thanks to a displacement mechanism. The use of

  fixing points provided on the vehicle allow

  nid rapid assembly and disassembly of the roof overhang and the latter can be used at the same time to ventilate the passenger compartment of the vehicle. In another embodiment according to the invention, the movement mechanism is mounted on brackets which are located near the end of the rear part of the roof facing the roll bar, and which are

  mechanically assembled with said rear part.

  Thanks to the arrangement of the brackets which engage from below with the roll bar, and thanks to the tightening of the projection and the rear part of the roof, an intimate contact and a secure retention of the two parts of the roof are obtained. this roof on the vehicle. In this case, it is not necessary to install after the fact

  attachment points on said vehicle.

  In an advantageous alternative embodiment, the

2502551U

  rear part of the roof has guide tubes

  which, approximately perpendicular to the upper face

  of this roof, can be fitted into holes

  verticals arranged in the extreme region of the platform

  S form of loading away from the roll bar.

  This use, for the tubular support frame, of the housings necessary for the installation of a

  tarpaulin provides both centering and fixing

tion adapted to the vehicle.

  Advantageously, the guide tubes constitute the tubes of a tubular support frame which runs along the corner areas of the roof and which descends along the corners of the rear part, said tubes projecting beyond the lower edges of the part. rear of the roof which are oriented towards the panels

  sides delimiting the loading platform. Incor-

  poration of another roll bar in the rear part of the roof increases passenger safety in the passenger compartment and gives said rear part of the roof great rigidity and high resistance to torsion. In addition, it allows you to walk on the rear part of the roof and it prevents snapping

  the latter, even at high speeds.

  According to the invention, it is also possible to

  ble, to increase the effect of the roll bar formed by the tubing, to drown the guide tubes in the, foam provided in two areas of ungle distant from the roll bar to form a corner post solid and, preferably, to mechanically connect the said tubes thanks to the glass fibers which surround the foam.

plastic material.

  In another alternative embodiment according to

  the invention, the rear part of the roof has,

  above the side panels delimiting the platform

  loading, centrally oriented recesses

  of the vehicle. This stamped region increases the resistance of the rear part of the roof in its lower area

  oriented towards the side panels.

  In another advantageous embodiment according to the invention, an angle iron, the horizontal branch of which is substantially perpendicular to each side panel, is fixed near the recesses in the space

  internal of the rear part of the roof, the angles

  two side panels being spaced one

  mutual spacing which corresponds substantially to space-

  between the side panels perpendicular to

  the longitudinal axis of the vehicle. This form of realization

  allows adjustment and adaptation after the fact

  fasteners according to possible variations

  (inherent in manufacturing) in the spacing

of the two side panels.

  In another embodiment, the mechanism for moving the roof overhang is mounted in the roll bar and it preferably consists of toggle fasteners. The fixing of this movement mechanism to the roll bar allows a secure anchoring on the vehicle and a large clamping force is thus obtained in the area of the seals interposed between the projection and the rear part of the roof. .

  In another particular embodiment variant

  rement advantageously according to the invention, the rear part of the roof is provided with clamping elements which, taking

  support against the roll bar from the inside

  of the vehicle are fixed to the internal face of said rear part. As a result of the depression of the front face of this rear part with respect to the roll bar, said rear part is automatically pushed towards its guide tubes in its zone

  posterior, under the combined effect of the connecting plates

  located behind the front and tilted doors

  relative to the longitudinal axis of the vehicle. This stuck

  provides an extremely good bond

  between the rear part of the roof and the vehicle.

  Finally, it is also possible to provide holes in the clamping elements which are aligned with

  the holes made in the upper corners of the ar-

  safety cage. Thanks to this use of holes already drilled in the vehicle, it is possible to obtain a mechanical connection between the rear part of the roof and the vehicle without installing new connection parts. The invention will now be described in more detail with reference to the accompanying drawings by way of non-limiting examples and in which: FIG. 1 is a perspective illustration of a vehicle fitted with an attached roof made of plastic;

  Figure 2 is a schematic side elevation

  that of a vehicle whose rear part of the roof forms the rear wall of the driver's cabin: FIG. 3 is a view similar to FIG. 2, illustrating another embodiment of the part

  rear of the roof and the projection of this roof in the lifted state

  vé; Figure 4 is a section of the roof overhang to

  proximity to the roll bar, parallel to the 'di-

  longitudinal section of the vehicle, along line IV-IV of Figure 1; Figure 5 is a fragmentary section of the corner post in the rear region of the rear part of the roof, along line VV of Figure 6: Figure 6 is a perspective view of the rear part of the roof in which is incorporated the tubular support frame;

  Figure 7 is a fragmentary section of the front

  cée du toit close to its fixing zones, parallel to the longitudinal direction of the vehicle, according to line VII-VII of Figure 1 Figure B is a plan view of said projection in which is incorporated the tubular frame of 250o2553 support ; and FIG. 9 is a fragmentary cross-section along the line IX-IX in FIG. 3, illustrating the lower region of the rear part of the roof oriented towards the side panels. Figure 1 illustrates a vehicle 1 having a sheet metal body. The latter comprises front doors 2, a support 3 for the windshield, as well as a wall bordering the rear part of the vehicle and comprising lateral rear panels 4 and a transverse rear panel 5 in which a tailgate engages. On this sheet metal body, is placed an attached roof 6 which, also usually called "hard-top" roof, comprises a projection 7 and a rear part 8. Said projection

  7 and. said rear part 8 each extend respectively

  tively from the front or rear end of the roof to the area of a roll bar 9 shown by a dotted line. Both the projection and the rear part form separate elements which

  are removably connected to the vehicle via the

  medium of fastening means 10 independent each

  of the others, and only one of which is represented schematically-

  ment in Figure 1 in the posterior area of the

rear 8.

  Figures 2 and 3 show that the rear part 8 can have several embodiments. Sure

  Figure 2, this part 8 constitutes a posterior wall

  driver's cabin, that is to say that it extends transversely to the longitudinal axis of the vehicle between the rear face of the front seats Il and the end, turned towards said seats, of a -loading platform 12 delimited by the panels 4 and 5. In each variant, the rear part 8 has a transition zone 13 covering the roll bar 9 in the direction of the front seats 11, as illustrated in particular in FIG. 3 It also emerges from this same figure that, in its extreme region facing the rear part 8, the projection 7

  it also has a transition zone 14 which overlaps

  che the transition zone 13 of said rear part.

  To bring the advance 7 from its rest position (illustrated in FIG. 2) to its position resulting from an upward pivoting [FIG. 3), a movement mechanism 15

  is interposed between vehicle 1 and said projection 7.

  Figure 4 highlights that the transition zones

  tion 13 and 14 are in the region of the roll bar 9. To obtain a smooth, hard-top roof

  continuous, the surface of its rear part 8 shows,

  ximity of the roll bar, a recess corresponding to the thickness of the projection 7. Thus, the transition zone 13 of this rear part 8 rests flat on

the roll bar 9.

  A gasket 16, for example a tubular gasket 17 made of rubber in the case under consideration, is threaded onto the anterior edge of the rear part 8 facing towards the projection 7. As mentioned in addition, a

  dotted, another seal 18 can also

  if necessary, be placed between the transition zone 14 of the projection 7 and the transition zone 13 of the part 8. When two seals 16 and 18 are placed near the roll bar 9, it is given birth, in addition to the predetermined labyrinth configuration, to an isolation chamber preventing traction phenomena from appearing in the area of the external face of the parts of the roof, even when strong depressions prevail in this

zoned.

  As can be seen from Figure 4, the ma-

  nism 15 of movement of the advance 7 consists of a

  toggle closure 19 mounted on a console 20.

  On the other hand, the rear part 8 of the roof is retained by means of clamping elements 21 which bear against the roll bar 9 from the internal face of the wall of the vehicle. These 1 0 elements 21 are connected by threaded connections 22 to the rear part 8. Said threaded connections 22 are

  anchored in metal reinforcements 23, which are incorporated

porées in the back 8.

  Figures 5 and 6 show guide tubes

  ge 24 which, incorporated in the rear part 8, appears

  are attached to a tubular support frame 25. As illustrated in particular in FIG. 6, this frame 25 includes the two guide tubes 24 housed in

  angles 26; a transverse or tra-

  support pour 28 connecting the two guide tubes and located above the tailgate 27; as well as two longitudinal supports 29 which, oriented in the longitudinal direction of the vehicle and located at the upper corners of the part 8, can be connected to each other by an additional support cross member 28 near the roll bar 9 when the roof is intended to support heavy loads. Longitudinal supports 29 and support crosspieces 28, as well as

  guide 24, are fixed suitable metal parts

  required in which the hinge fixing screws 30 and 31 of the tailgate 27 can be anchored, the members constituting a lock 32 of this tailgate 27, as well as the articulations of the pneumatic jack for lifting said tailgate 27 and those of tubes 33 of a gallery 34 l see

Figure 1).

  Furthermore, the guide tubes 24, which can be inserted into vertical holes 36 of the transverse rear panel 5 by means of tubular appendages 35 projecting beyond the lower edges of the part -8, are embedded in the foam of the uprights d 'angles 26

  obtained by mous.sage of angle zones 37. To reach

  have a high resistance to tearing of the appendices

  these tubulars 35 ensuring the anchoring of the rear part 8 on the vehicle 1, each corner post 26 obtained by foaming is mechanically assembled, by additional layers of polyester reinforced with glass fibers, with the contiguous zones of the rear part 8 made of reinforced plastic

glass fibers.

  FIG. 7 represents the anterior end of the projection 7 which is provided, for the purpose of reinforcement,

  of support sleepers 38 incorporated in said forward

  and perpendicular to the longitudinal axis of the vehicle.

  The projection 7 is further connected to hooks 39 which, in turn, are advantageously incorporated in said projection. These hooks are engaged in retaining stops 40 mounted on the vehicle near the windshield support 3. Pushers 41 are arranged on the side of said support 3 opposite the stops 40 and they consist of angles which, in the assembled state, bear against said windshield support. The attachment to the projection 7 is ensured by screws 8. A lip seal, arranged on the upper face of the support 3, closes the intermediate space between. this support

and advanced 7.

  In addition, a lip seal is still threaded on the anterior edge of the projection 7, in order to hermetically seal the intermediate space.

  between this advance and the support 3.

  As can be seen in FIG. 8, the projection 7 is provided, in its longitudinal direction and in the transverse direction of the vehicle, with at least two support cross-members 38 which, ensuring its reinforcement, are incorporated in said projection made in a plastic material reinforced with glass fibers. The hooks 39, in engagement with the retaining stops 40 near the windshield support 3, are fixed to the support crosspieces located at the front in the direction of

  displacement. The pushers 41 are also subject to

  connected to these crosspieces 38. The ends of the toggle fasteners 19 which are oriented towards the projection 7 are fixed to the support crosspiece 38 located at the rear in the direction of movement. The pushers 41 have only the function of preventing the hooks 39 from being released in the region of the windshield support 3,

  especially when the projection 7 is raised by pivoting.

  FIG. 9 shows the lower region of the rear part of the roof near the side panels 4. To increase the solidity of the rear part 8 in its zone of contact with each side panel 4, a recess 42 is provided in the region which an angle 43 is secured to the part 8 by

  bonding or through mechanical elements of-

  fixation. Thanks to suitable spacers or to a width, chosen accordingly, of the horizontal branch of the angle iron 43, possible deviations in the spacing dimensions of the side panels 4 perpendicular to the longitudinal axis of the vehicle can be compensated. In addition, it is possible to have, in the region of the recess 42, an embellishment 44 serving to mask any means of fixing between the rear part 8 and the angle iron 43. In addition, it is also possible to drill in the rear part of the roof, behind such a hubcap 44, orifices 45 which

  can be used to ventilate the space between

  ne of the vehicle when the hard-top type roof "

is used.

  To mount the hard-type roof

  top "according to the invention, the tubular appendages 35

  from the rear part a are threaded into the vertical holes

  cals 36 of the vehicle and then this rear part is

  folded down on the roll bar 9. The transit area

  tion 13 of said part 8 is pressed intimately against said arch 9 by means of two clamping elements 21, which are connected by threaded connections to said rear part 8 after the latter has been put in place. As a result of this depression obtained thanks to said clamping elements 21, the rear part 8 is pushed towards the vertical holes 36 by

  through the body panels which extend

  tooth obliquely behind the front doors 2 and, as a result, the tubular appendages 35 are clamped against the vehicle body. This results in a solid and secure fit of the rear part of the roof, even when the vehicle is traveling over rough terrain, if

  although no noise nuisance or constraint

  te traction is manifested inside 'said vehicle. Immediately after mounting the rear part 8, the hooks 39 of the projection 7 are hooked in the retaining stops 40 of the windshield support 3 and the transition zone 14 of said projection is folded over the transition zone 13 of said part 8. A

  the folded-down state, this projection 7 is connected to the farm

  ture à genouillère 19. Once this connection between the projection 7 and the closure 19 established, the pushers 41 are mounted which bear against the internal face

of the windshield support 3.

  To mount the rear part 8 when the latter constitutes the rear wall of the driver's cabin, the transition zone 13 of this part is slid over the roll bar 9, then it is subject to the latter using the elements clamping 21. In the area of the loading platform 12 of the vehicle 1, the connection is provided by quick couplers or by mechanical fixing means. For

  sealing the internal space between the

  tie 8 forming rear wall and platform 12,

  suitable seals can be used.

  To guarantee a good introduction of force, the parts included for fixing the components

  lock or anchors in the roof "hard-

  top ", preferably made of polyester reinforced with glass fibers, are incorporated in the parts

  molded, as is notably the case of the tubular frame

support area.

  The production of the projection and the rear part of the roof can also be carried out by stamping

-2502553

  plastic sheets or plates, or sheets of ferrous or non-ferrous metals. When using

  stamped plastic sheets, a laminated layer

  born of glass fibers can be applied to the internal face of the parts of the roof, in order to increase solidity. Particularly when the roof is intended to support heavier loads. it is recommended to make the parts of this toi.t according to a sandwich design,

double envelope.

  It goes without saying that many modifications can

  can be brought to the attached roof described and shown,

  without departing from the scope of the invention.
