The present invention relates to a process for
assembling two elements, such as panels capable of
forming an outer skin and an inner skin of a vehicle
door.
At present the connection on a metallic door
between the outer skin and the inner skin of a door is
ensured by tacking and fastQning the first on the second;
leaXproofness is ensured by a strip of mastic or of
adhQsive.
On a plastic door, the connection between the two
p~n~ ~ff~cte~ ~r adhesi~ bond~g.- ~n bo~h c~ses,
the outer skin cannot be separated without damage tG the
door.
In accordance with the process which is the - .
obtect of the invention, a certain number of holes for
screws are drilled in the fir~t element, a layer of anti- ..
adhesive agent i8 deposited on the surface of tho first
element, drilled pl~tes are pl~ced against one of the
faces of this element, opposite the abovementioned hole~
~0 the plates are fixed to the said element by screw~, a
l~yer or strip of adhesive is deposited on the f~ce of
the second element which is turne~ towards the.fir~t
eiLa~en~ and;.th~ ~J~ o~:th# ~v~ me~s i8 ~f~ected~ . . -.:
br ~dhesi~Je~e.-di~ng,.~theif~rst ~ement then b~ing reDov--:
able and remount~ble by unscrewing and screwing up again.
Remounting of the first element, whlch can for -.
example be ~n inner panel of the vehicle door, is easily .-
done since its position has been predetermined by
~dhesively bonding the plates on the second element.
In the case of a vehicle door, this arrangement
h~s the ~dvantage that it permits a rapid and dis-
assemblable connection between two panels of a, for ..
ex~mple, plastic, door.
Ihe assembling of two elements such as panels
~ccording to this process is.ch~r~cterized in th~t the
first element is provided on one of it~ faces with plates
flxed to the element by ~crew , the surface of this .-~
ol _ nt surrounding the pl~tes is coated with an anti-
~dheJive aq~nt, the face of the second element which i8

turned towards the first element is coated with a strip
of adhesive facing the plates, which ensures a connection
between the two elements, which can then be separated by
~n~crewing.
The invention will now be described with refer-
ence to an embodiment illustrated by way of nonlimitative
example in the drawings.

In Fig. 1,~two elementa 1,, 2'formed by pan~Ls ~o ' -'
be~sOEmbl'Qd,csn,~e~ _ n~ th~ f~rfft pan~l l-is prov~ded~'
on one of its faces, namely its face,turned~towards the
25' second panel 2, with a series,of plate3 3, made for , ' , -
example of steel. These plates 3 are fixed to the panel
1 by respective,screws 4 capable of passing 'through
corresponding tapped holes 5, 6 respectively arranged in
the panel 1 and in each plate 3, the latter being dis-'' -
tributed at regular intervals at the perimeter of the
panel 1, from which they protrude. The plates 3 are ''
partially housed in undercuts 9 of the element 1, from ''~' -
which they likewise partially protrude towards the
panel 2.
In the vicinity of its periphery, the second
p~nel 2 has recesses 7 adapted to receive the plates 3 of f
the panel 1 and having dimensions slightly larger than
those of the plates 3, t~king into account the po~ition-
ing tolerances between the two panels. The surface of the
ZOl9901
-- 3 --
panel 1 i~ coated with an anti-adhesive 8 (Fig. 2) while
a strip of adhesive 10 is deposited on the inner face of
the second panel 2 on at least part of its periphery, in
the recesses 7 and between the latter. This strip 10
extends opposite a corresponding strip formed by the
anti-adhesion agent 8.
To assemble the two panels 1 and 2, the procedure
is as follows:
- first of all, the strip 8 of anti-adhesion
agent i~ deposited on the face of the panel 1 which is
tur~d t~ward~ the pa~L ~
- the drilled plates 3 are fixed on the face of
the panel 1 which is turned towards the panel 2 by virtue
of the screws 4 screwed into the corresponding holes 5,
6 (Fig. 2),
- a layer of adhesive formed, for example, by the
strip 10, is deposited on the face of the second panel 2
turned towards the panel 1 and the first panel 1 is then
applied to the second panel 2 in such a wsy as to house
the plates 3 in the recesses 7. The plates 3 snd the
panel 1 are then fixed to the panel 2 by the layer of
adhesive 10, while the anti-adhesive agent 8 between the
pl~ ~ p~r~ts th~ strip o~ ~iv~10 fral~ ~rCiJ~
ing it- ~fect. ~e~ t~;par~l~ 1 ar~ 2 ~ t~u~ firmly~
2!i ~oined. to each other by adhe~ive bonding at the housings
7 of the plates 3. In addition, the strip of adhesive 10
en~ures leakproofness between the psnels 1, 2.
To remove the first panel 1, it i~ then suffi-
cient to unscrew the screws 4, the plates 3 remaining
fi~ mly fixed to the panel 2 by adhesive bonding. The
remounting of the panel 1 can be effected without dif-
ficulty by screwing the screws 4 back into their cor-
responding holes 5, 6.
The panel~ 1 and 2 can be metallic or made of a
3S pla~tic material and can consi~t, for example, of an
outer ~k$n 2 and an inner skin 1 of a vehicle door 11, as
repre~ented in Fig. 5. It will be noted that, after
re~v~l of the outer skin 2, the exact initial position
can be reloc~ted ea~ily and autom~tically by virtue of

the plates 3, which have remained firmly fixed to the
outer skin 2.
As a variant, the recesses 7 and undercuts 9 can
be replaced solely by recesses 7 or solely by undercuts
S 9, the face of the opposite panel then being flat.
