Description

- i - 2465858

  The present invention relates to a hinge attachment for a door.

  tes of motor vehicles o one of the flaps of a hinge with two flaps assembled by being able to pivot around a hinge pin, is fixed in a non-removable manner on the door of the vehicle while the other flap of hinge is fixed in being removable, by means of threaded bolts, on a fixing element arranged on the door frame integral with the vehicle body. Hinge fasteners of this type are used for removable hinges on motor vehicle doors and are mainly used

  to mount and adjust the door on the gross vehicle body.

  The present invention more particularly relates to a hinge fixing of the type described above which allows with a manufacturing cost

  and assembly as small as possible, reassemble the door, adjusted initial-

  ment in the rough body, in its position of primitive adjustment, without requiring any particular work or special technical devices. The fixing of the hinge must in particular allow, at any time, the disassembly and reassembly of the door in its position of primitive adjustment. To achieve this objective, the present invention proposes that the element / and the hinge flap comprise reciprocal guide surfaces which

slide on top of each other during assembly of the mounting bracket

  and are orthogonal to the corresponding bearing surfaces of the fixing element and the hinge flap. These guide surfaces are preferably

formed by projections and recesses, provided on the fixing element

  tion and the hinge flap, said projections closely engaging in

said recesses, and are advantageously designed independently of the devices

  fixing the hinge flap on the fixing element. Thus, the threaded bolts ensuring the fixing of the hinge flap on the element

  are free from any guiding function and the hinge flap

  re located on the side of the door frame, so the door itself can be fixed on the fixing element exactly in its original position of horizontal and vertical adjustment. The primitive adjustment and according to the definitive invention

  of the door is provided exclusively by the parts designed for this purpose, except

  see the hinge flap and the fixing element. When the fixing element is fixed to the door frame by known means, such as by

  example, a spot weld or a boss weld, it can be ad-

  provided that the fastening element is disposed therein in an irremovable manner which excludes any risk of subsequent modification of its position. This also ensures that the guide surfaces provided on the fixing element and the

  hinge flap allow you to reassemble the vehicle door at any time

  steps exactly into its original position of adjustment.

  According to a preferred embodiment of the invention, the guide surfaces consist of, on the one hand, a slot-shaped recess provided in the fixing element and having a rectangular horizontal projection and, on the other hand, a tongue cut out at the edge of the flat part of a hinge flap rolled in sheet metal, protruding on said edge and

  folded orthogonally to the plane of the hinge flap.

size of the recess provided in the fixing element obviously corresponds

  the cross section of the tongue cut out at the edge of the door

  so that these two parts can engage as guide surfaces

  one inside the other with very little play when assembling the fixture

  hinge. To facilitate the engagement of said tongue of the hinge flap in the recess of the fixing element, the front end

  of the tongue has an arc shape. According to another character-

teristic of the invention, it is proposed that on the one hand the fixing element

  tion consists of a stamped sheet metal part with fixing surfaces

  tion orthogonal to each other, reciprocally resting by means of lateral connecting walls and that, on the other hand, the edges of the flat part of the hinge flap, orthogonal to the axis of the hinge, comprise peripheral zones folded back orthogonally to the plane of said hinge flap. In the hypothesis of the embodiment presented, the peripheral regions folded back orthogonally to the plane of the hinge flap may, with respect to the corresponding counter-surfaces on the fastening element, present a greater clearance than that between the side walls of the 'recess in the form of a slot in the fixing element and the folded tongue, cut at the edge of the hinge flap. It should be noted that the folded peripheral zones of the hinge flap ensure, during

  from the assembly of the hinge fixing, a certain guide function

dage relative to the vertical adjustment of the vehicle door while the folded tabs of the hinge flap ensure the horizontal adjustment

from the hinge pin.

  According to another embodiment of the invention, the fastening element may consist of an angular profile segment and provided with pins which have a convex free front end, projecting from the bearing surface of the flat part. of the hinge flap and cooperate, during the assembly of the hinge fixing, as guide surfaces

with counter surfaces formed by bores in the hinge flap.

  The rounded shape of the free front end of the pins forming over-

  guide faces significantly facilitates the assembly of the hinge attachment

  re. The guide surfaces are not necessarily formed by grooves

batteries provided on the fixing element but can also be made up of

  killed by tenon-shaped projections, pushed back into a seat, provided on the

  plane tie of the hinge flap and cooperating, during the assembly of the fixing

hinge, with counter surfaces formed by bores in

the fixing element. It is obviously possible to provide pin

  forming guide surfaces on the flat part of the hinge flap.

  According to another embodiment of the invention, at the two ends

  front mites facing a trestle-shaped fastening element,

  consisting of a sheet metal segment, a folded tongue orthogona- is cut

  Lement to the bearing surface of the flat part of the hinge flap, cooperated

rant, when assembling the hinge attachment, as a surface

guide with a counter surface formed by the front surfaces of the vo-

  hinge let. As this design of the guide surfaces of the fastening element and of the hinge flap only ensures a vertical adjustment, it can also be provided, a projection parallel to the axis of the hinge, either on the fastening element , either on the hinge flap, which engages in a corresponding recess in the hinge flap, respectively

the fastening element to ensure the horizontal adjustment of the load flap

  relative to the fastener.

  According to another embodiment of the invention, the fastening element consists of a segment of very thick flat material, the flat lateral surfaces of which cooperate, during the assembly of the fastening

  hinge, as guide surfaces with counter-surfaces

led by the peripheral area of the flat part of the hinge flap,

  folded orthogonally to said flat part. A tongue cut out at the edge

  free longitudinal of the flat part of the hinge flap and folded or-

thogonally to said flat part, engages as a guiding surface

  in a recess provided in the fixing element and having a projection

horizontal rectangular tion.

  Still according to the invention, the fastening element may have a cross section of U-shaped profile whose projecting branches cooperate, during the assembly of the hinge fastening, as guide surfaces with counter-surfaces. correspondents formed by

  lateral surfaces of a hinge flap constituted by a segment of ma-

  material. very thick plate, to guide the hinge flap and

keep the original fit of the vehicle door. Similarly, the concept

  tion of this embodiment of course falls within the scope of the

present invention.

When the construction of the body saves a very small space

for mounting operations, a non-removable fixing of the fixing element

  fixing on the door frame on the bodywork can sometimes be defective

vorable in terms of ease of assembly and disassembly of the door

in a predetermined, adjusted position.

To meet the requirements of this hypothesis, the present invention

  proposes that a substantially flat plate-shaped fastening element,

preferably made of a sheet metal plate or a segment of flat material of

very thick, can be assembled to the door frame on the bodywork

this to threaded bolts and the hinge flap located on the side of the frame

  door can be assembled to the fixing element using other bolts

  letés; the recesses provided in the flat part of the hinge flap,

  pectively the fixing element, cooperating with one or the other series of

threaded bolts, have a larger diameter than that of the rod

known as threaded bolts. The arrangement of one of the parts of the hinge fixing relative to its other part, respectively to the door frame,

  is predetermined by means forming guide surfaces and sienga-

  closely managing each other. The use of a metal plate

  the substantially flat as a fastening element allows first of all to reduce the space required for mounting the hinge fixing. In addition,

as a series of threaded bolts is used to secure the element

  fixing on the body, and the hinge flap on the fixing element

  it is possible to take the mounting conditions into account when measuring

  re o, depending on the embodiment chosen, the door is adjusted by orienting. either the hinge flap compared to the element of

fixing, or the fixing element relative to the door frame. A die-

subsequent placement of the adjusted door position is excluded in both cases. When the door is adjusted by orientation of the hinge flap relative to the fixing element, the latter can only be assembled to the door frame on the bodywork in a position determined in advance by means of means forming surfaces of

guiding and engaging closely with each other and, to demon-

door, simply detach the fixing element from the door frame.

  te which does not touch the adjustment position of the hinge flap relative to the fixing element. Otherwise, when the door is adjusted by orientation of the fastener relative to the frame

  door on the body, the hinge flap is assembled to the

  fixing in a position determined in advance by means of

  re means forming guide surfaces and engaging closely with each other and, to dismantle the door, it suffices to detach the

hinge flap of the fastener so that the door is needed

  sary reassembled in its original adjusted position, which does not affect the adjustment position of the fastener relative to the door frame on the body. To allow adjustment of the door in the body in any position, it is provided according to the invention

that the recesses provided in the flat part of the hinge flap or the element

  fixing ment, cooperating with one of the series of threaded bolts and

the diameter is larger than that of the rods of the threaded bolts, present

  attempt a horizontal projection of square shape with light sides

  smaller than the distance between the two opposite sides of the hexagonal head of the threaded bolts. A similar design of the recesses

characterized by a larger dimension than the rod of the bolts thread-

  tees, will of course be retained for any other shape of the head of said bolts

  threaded. The fastening element is assembled to the door frame on the body.

series in a predetermined position, by means forming guide surfaces and engaging closely with each other, the adjustment of the door being obtained by orientation of the hinge flap relative to the element of fixation. In this view, the fixing element in the form of a plate, flat and preferably consisting of a sheet metal segment,

has two guide surfaces formed by protrusions in the form of a

  no which cooperate with corresponding counter-surfaces formed by

  holes in the wall of the door frame upright. Thus, the posi-

tion of the fastener relative to the door frame is determined in advance without the possibility of modification. In addition, the threaded bolts

used to assemble the fixing element to the door frame also serve

  guide surfaces which excludes any risk of improper mounting.

  The threaded bolt bores used to assemble the fastener

to the door frame are advantageously arranged, with respect to the long axis

-6- tudinal of the hinge flap, one directly in front of the other while the projections serving as guide surfaces are arranged, diagonally

and opposite each other, which excludes given the tolerances pos-

if possible, any risk of inclined positioning of the fastening element during subsequent reassembly. Still according to the invention, on the fastening element assembled in a

  predetermined position at the jamb of the door frame by means of

  running tightly together and threaded bolts, can be fixed a shutter

  hinge in any position thanks to threaded bolts

  pouring recesses provided in the hinge flap and having a larger diameter than the rod of said threaded bolts. Like the threaded bolts that assemble the hinge flap to the fastener

  are no longer unscrewed when dismantling the door, it can be provided

  Another characteristic of the invention is that after adjusting the por-

  of the vehicle, the hinge flap is held on the fixing element

  in its position corresponding to the adjusted position of the hinge axis

thanks to a temporary weld, so that even unintentional unscrewing

  conceal threaded bolts securing the hinge flap to the fi-

  fixing cannot lead to a modification of the adjusted position of the door

to be reassembled later.

According to another embodiment of the invention, an element

  fixing plate-shaped can be fixed in its adjusted position

  tee on the door frame of the vehicle body by means of threaded bolts cooperating with the recesses having a larger diameter than the rod of said threaded bolts, and comprises recesses constituting guide surfaces cooperating with counter-surfaces formed by tenon-shaped projections provided on the hinge flap. In this case, the hinge flap is assembled to the fixing element in

  being removable and, consequently, its position relative to said fixing element

tion is determined in advance unchangeably thanks to, on the one hand, means cooperating closely together such as, for example, tenon-shaped guide surfaces engaging in bores and, on the other hand, the position of the threaded bolts. To allow an exact adjustment of the shutter

  hinge relative to the fixing element taking into account certain tolerances

  The invention proposes that the bores receiving the threaded bolts for fixing the hinge flap to the fixing element are arranged one beside the other with respect to the longitudinal axis of the flap

hinge while the means forming guide surfaces and cooperate

  and rant closely together are arranged diagonally / opposite each other with respect to said longitudinal axis. In addition, the hinge flap is fixed while being removable but in an invariable position on one fixing element by means of threaded bolts. After adjusting the door

  vehicle, the fastening element is held on the upright of the door frame

  te in its position corresponding to the adjusted position of the axis of the

  thanks to a temporary weld. Thus, even involuntary loosening-

  concealing threaded bolts ensuring the assembly of the fixing element on the door frame upright cannot lead to a modification of the

  adjusted position of the door to be reassembled later.

  attached drawings by way of nonlimiting example.

We will ultimately find a nomenclature of the different benchmarks used

during the description.

A fixing element (2) is fixed as known per se, for example by spot welding or boss welding, on the door frame (1) of the

  vehicle body, partially shown in Figures 1 and 3. On the element

fixing part (2) is fixed, by threaded bolts (3) and possibly nuts (4) the flat part of one of the hinge flaps (5) which comprises two flaps (5) and (7) assembled in able to oscillate around a hinge pin (6). The other hinge flap (7) is arranged as known per se on the door (8) of the vehicle and normally irremovable. In accordance with the embodiment presented in Figures 1 to 2, the fixing element (2) consists of a stamped sheet metal part having fixing surfaces

  (10), (11) orthogonal to each other, supporting each other-

ment by means of lateral connecting walls (9). During the as-

  semblage-of the hinge attachment, the hinge flap (5) and the element

  fixing (2) are reciprocally brought by guide surfaces or-

  thogonal to their reciprocal bearing surfaces so that the door of the

hicule to be permanently mounted thereafter must necessarily be mounted in its primitive-adjusted position in the rough bodywork. The guide surfaces consist of, on the one hand, a slot-shaped recess

(12) provided in the fixing element (2) and having a horizontal projection

rectangular zontale and, on the other hand, a tongue (14) cut at the edge (13) of the flat part of a hinge flap rolled in sheet metal, projecting from

  said edge (13) and folded orthogonally to the plane of the hinge flap (5).

  The front end (15) of the tongue (14) cut at the edge (13) of the

hinge let is characterized by the shape of its edge in an arc.

  The tongue (14) guarantees the horizontal determination of the axis of 1 char-

in its position of primitive adjustment. The vertical determination of the hinge axis is ensured by the fact that the edges of the part

  plane of the hinge flap (5), orthogonal to the axis of the hinge,

  carry peripheral zones (16) folded back orthogonally to the plane of said hinge flap, which during assembly of the hinge attachment, slide as guide surfaces on counter surfaces formed by the

  lateral connecting walls (9) of the fixing element (2).

  In accordance with the embodiment of the invention presented in FIG. 3, the fixing element (2) consisting of an angular profile segment is provided with pins (18) which have a free front end (17) curved, projecting from the bearing surface of the flat part of the flap

  hinge (5) and cooperate when assembling the hinge attachment

nière, as guide surfaces, with counter-surfaces formed by bores (19) in the hinge flap (5). In this view, the hinge flap consists of a hinge profile and its flat part has a thickness sufficient to be provided with bores (19) sufficiently long, serving as counter-surfaces to the guide surfaces of the pins (18) .The two pins (18) cooperating as guide surfaces with the bores (19) guarantee a reciprocal adjustment or alignment of the hinge flap (5) and the fixing element, independent of the bolt

  fixing thread (3), so that the vehicle door (8) is

  necessarily mounted in its previously adjusted position, completely

  hanging threaded fixing bolts (3).

  According to the exemplary embodiment presented in FIGS. 4 and 5, the fixing element (2) consists of a segment of very thick flat material whose flat side surfaces (20) cooperate, during the assembly of

  the hinge fixing, as guide surfaces, with counter

surfaces formed by the peripheral zone (21) of the hinge flap (5)

  folded orthogonally to its flat part. A tongue (23) cut at the free longitudinal edge (22) of the flat part of the hinge flap (5) and folded orthogonally to said flat part of the hinge flap (5), engages as a guide element in a recess (24) provided in

the fixing element (2) and having a horizontal horizontal projection

  gular. This guarantees that the door to be reassembled later is fixed

on the frame (1) of the bodywork respecting the primitive hori-

  zontal and vertical of the hinge axis.

  According to the embodiment shown in Figure 6, the fastening element (2) has a U-shaped profile cross section whose protruding arms (25) cooperate, during the assembly of the fastening

  hinge, as guide surfaces with corresponding counter-surfaces

supporting elements formed by the lateral surfaces (26) of the hinge flap (5)

  consisting of a segment of very thick flat material. In the hypo-

  thesis of a construction of this type, the horizontal adjustment of the door, respectively of the hinge flap (5), from the axis of the hinge, can also be ensured by the threaded fixing bolts (3) so

all that is required is simple vertical directional guidance of the load flap.

  A similar attachment method is shown in Figure 7. A loading flap

  fixing (2) consisting of a segment of flat material of great thickness.

  Here again, the horizontal determination of the position of the axis of the

  This can be ensured by the threaded fixing bolts (3).

  According to the embodiment shown in Figures 8 and 9, the fixing element (2) consists of an angular profile segment and the flat part of the hinge flap (5) consisting of a profile has projections

  (29) in the shape of a tenon, pushed back into a seat, cooperating during the assembly

fixing of the hinge fixing, as guide surfaces with

  counter-surfaces formed by bores (30) in the fixing element (2).

  According to this embodiment, the protrusions (29) in the shape of a tenon of the hinge flap (5) provide complete guidance and adjustment of the flap.

tion (3) are free from any adjustment function.

  According to the embodiment presented in Figures 10 to 11, both, ex-

  front hoppers facing a fastening element in the form of a che

  valet, made of a sheet metal segment, is cut a tongue (32)

  bent orthogonally to the bearing surface (31) of the flat part of the hinge flap (5), cooperating during the assembly of the hinge attachment as guide surfaces with counter-surfaces formed by the

sure-

  front faces (33) of the hinge flap (5). As we can see more

particularly in figure 10, the horizontal adjustment of the axis of the

nière (6) is ensured by the contact of the front surface (34) of the shutter

hinge with door frame (1).

In accordance with the embodiment presented in FIGS. 13 to 15, a fixing element (2) is assembled while being removable from the upright of the frame

  door (1) thanks to threaded bolts (47). In order to determine a

taine orientation relative to the amount of the door frame, the fastening element (2) comprises extensions (48) in the shape of a tenon, serving as guide surfaces, which engage in recesses (49) serving

  counter surfaces and provided in the wall of the door frame. The bolts fi-

  i l - lets (47) are arranged directly opposite one another with respect to the longitudinal median axis of the flat part of the hinge flap (5), and

  outside of said flat part, and pass through bores of dimension

* substantially identical parts, provided in the fixing element (2) and in the amount of the door frame. The guide surfaces (48) and (49) of the fixing element (2), respectively of the upright of the door frame (1), are arranged diagonally and opposite one another with respect to the 'longitudinal central axis of the flat part of the hinge flap (5). The nuts

  (53) cooperating with the threaded bolts (47) are welded on the inner side

the door frame wall. The t-shaped extensions (48)

not of the fastening element (2) consist of simple projections.

  For the adjustment of the vehicle door, the hinge flap (5)

is fixed by threaded bolts (54) on the fixing element (2). In this-

At the end, the threaded bolts (47) pass through larger recesses (56).

of dimension than the rod (55) of the threaded bolts (47), provided in the hinge flap (5). The recesses (56) have a horizontal projection of square shape whose sides are slightly smaller than the distance

  between two sides facing the hexagonal head (57) of the bolts

  letés (54). Said threaded bolts also engage in nuts (58) welded to the rear face of the fixing element (2). To avoid

a modification of this adjusted position, due to an involuntary loosening-

  hide threaded bolts (54), the hinge flap (5) is held in

  its position adjusted by a temporary weld (59).

In accordance with the embodiment presented in FIGS. 16 to 18, it is provided that, when the vehicle door is dismantled, the hinge flap (5) can be detached from the fixing element (2), that is to say to say that

  the hinge flap is in a predetermined position, disposed on the element

fixing by being removable, thanks to threaded bolts (54) and

means cooperating closely together. Compared to the median longitu-

  dinal of the flat part of the hinge flap, the threaded bolts (54) are arranged one next to the other, while the means cooperating closely together are arranged diagonally and opposite each other

relative to the longitudinal axis of said hinge flap. The means cooperated

rant closely together are formed, on the one hand, by extensions

  (68) in the shape of a pin of the hinge flap (5), serving as guide surfaces.

  dage, and, on the other hand, bores (69) provided in the fixing element (2) and serving as counter-surfaces. The tenon-shaped extensions (68)

  may consist of simple projections from the flat part of the hinge flap. The threaded bolts (54) pass through bores (60) and (61) which correspond to them and are provided in the hinge flap and the fixing element, and engage in a nut (64) provided and preferably welded to the rear face of the fixing element. By threaded bolts (47), the fixing element (2) is fixed to the upright of the door frame (1) in a determined position, corresponding to the adjusted position of the vehicle door. To find the position of the fixing element (2) relative to the

  door frame upright, which corresponds to the door adjustment position

  te, the recesses (71), provided in the fixing element and cooperating with the rod (70) of the threaded bolts (47), have a larger diameter than

  that of said rods (70). The recesses (71) have a projection ho-

square shaped rice whose sides are slightly smaller than the

  distance between two sides facing the hexagonal head (72) of the bou-

threaded links (47). The latter engage in a nut (73) welded to the rear face of the wall of the door frame upright. In addition, the element

  fastening is fixed to the door frame upright by a provisional weld

  evening (74) in order to avoid any risk of modifying the door during assembly

  cation of the adjusted position thereof, due to an involuntary loosening-

re threaded bolts (47).
