[0001] The present invention relates to a vehicle door handle.
[0002] More specifically, the present invention relates to a handle of the type comprising
a fastening structure for connection to the vehicle door; a lever connected to the
fastening structure and which is gripped by a user; and a sensor or detecting antenna.
[0003] In most applications, the lever has an inner cavity communicating with the outside
through an opening, and into which the antenna or sensor is inserted through the opening,
which is then closed by a plug.
[0004] Such a handle is known from document
EP-A-1035276 which presents a door handle comprising a grip member, intended to be gripped in
use by a user, fitted to fastening means connected to the door. The grip member defines
an inner cavity housing detecting means which are maintained in a fixed position inside
the cavity by a plugging body housing an end portion of the detecting means.
[0005] To insert the antenna or sensor easily inside the cavity, the inside of the cavity
is normally larger than the antenna or sensor, so that, during normal operation, the
antenna or sensor vibrates inside the lever, thus resulting in annoying, undesired
acoustic emissions and, in many cases, in rapid failure.
[0006] Besides failing to provide an effective solution to the problem, reducing the clearance
between the lever and the antenna or sensor also makes it more difficult to insert
and position the antenna or sensor correctly.
[0007] Moreover, being normally flexible, the lever, when gripped to open or pushed to close
the door, flexes and transfers the external pressure to the antenna or sensor, which,
as is known, is sensitive to mechanical stress. As a result, the antenna or sensor
soon breaks down and must be replaced at far from negligible cost.
[0008] It is an object of the present invention to provide a vehicle door handle designed
to provide a straightforward solution to the above problems, and which, in particular,
provides for a high degree of efficiency and reliability at all times, while at the
same time being relatively cheap.
[0009] According to the present invention, there is provided a handle for a vehicle door,
as claimed in claim 1.
[0010] In the handle defined above, said elastic forcing means conveniently act on a surface
of said detecting means facing said fastening means, to push the detecting means outwards
of the grip member.
[0011] A non-limiting embodiment of the invention will be described by way of example with
reference to the accompanying drawings, in which:
Figure 1 shows a section, with parts removed for clarity, of a preferred embodiment
of the handle according to the present invention;
Figure 2 shows a section along line II-II in Figure 1;
Figure 3 shows an exploded view in perspective of a detail of Figure 1;
Figure 4 shows a view in perspective of a variation of the Figure 3 detail.
[0012] Number 1 in Figure 1 indicates as a whole a handle for a vehicle door not shown.
[0013] Handle 1 comprises a fastening structure 2, which is connected integrally in known
manner, not described in detail, to the door (not shown); and a lever 3 for controlling
a lock (not shown) on the door.
[0014] Lever 3 comprises an end portion 4 hinged to structure 2, in known manner not described
in detail, to move, with respect to structure 2, to and from an extracted position
to activate the lock (not shown). Lever 3 also comprises a hollow, elongated, intermediate
portion 5, which is gripped manually, in use, by a user; and an end portion 6, opposite
portion 4, which extends through structure 2 and is connected to the door lock (not
shown).
[0015] Intermediate portion 5 comprises a longitudinal front wall 7 facing, in use, the
user and defined internally by an inner surface 7a; and a rear wall 8 facing front
wall 7 and adjacent, in use, to the body of the door. Together with the rest of lever
3, walls 7 and 8 define an elongated cavity 9 communicating with the outside through
two facing end openings 11 and 12. Opening 11 extends through end portion 6; opening
12 comes out inside a further cavity 13 formed in portion 4; and cavity 13 is closed
partly by a cover 14 to define a chamber 15, and a conduit or passage 16 connecting
chamber 15 to the outside.
[0016] A known detecting device 18 is housed radially loosely inside elongated cavity 9,
and, in the particular example described, comprises a hollow outer casing 19 formed
in one piece or by two connected half-shells, and an antenna or sensor 20 locked inside
casing 19 and connected to wiring 21. Wiring 21 comes out of an end portion 23, adjacent
to chamber 15, of casing 19, and extends outside through chamber 15 and passage 16
(Figure 1).
[0017] As shown in Figure 1 and particularly in Figure 2, end portion 23 of casing 19 is
connected to intermediate portion 5 by an anchoring device 24 comprising an annular,
conveniently elastic body 25 partly surrounding end portion 23 and which is forced
inside cavity 9 to form a hinge enabling casing 19 to rotate to and from wall 7.
[0018] As shown in Figure 1, casing 19 is pushed against surface 7a of wall 7 by an elastic
device 28 interposed between wall 8 and an end portion 26, opposite portion 23, of
casing 19.
[0019] In the example described and shown in particular in Figures 1 and 3, device 28 comprises
a supporting plate 29 resting on a portion of wall 8 adjacent to end portion 6 and
end opening 11; and an elastically deformed lever 30, which is integral with plate
29, forms an acute angle A with plate 29, and terminates with a fastening portion
31 resting against an inner surface of portion 26 facing structure 2. Portion 31 has
two adjacent holes 32, each engaged by a respective pin 33 integral with casing 19
and projecting from casing 19 parallel to the other pin 33. The portion of plate 29
opposite the portion integral with lever 30 is connected integrally to a cover 35
for closing end opening 11. In the particular example described, cover 35, supporting
plate 29, and lever 30 form part of a single body 36 formed in one piece and connected
releasably to portion 6 by a removable retaining pin 37.
[0020] In the Figure 4 variation, plate 29 is separate from cover 35; lever 30 is connected
directly and integrally to casing 19; and elastic device 28 and casing 19 - or at
least part of casing 19, if this comprises a number of parts - preferably form part
of a single body 38 formed in one piece.
[0021] In actual use, annular body 25 provides for easily hinging one end of detecting device
18 and allowing the rest of device 18 to oscillate, inside cavity 9, to and from wall
7. And, in parallel, elastic device 28 forces portion 26 of casing 19 elastically
against wall 7, so that the efficiency of detecting device 18 is in no way impaired
by any external force transmitted to intermediate grip portion 5 by the user, or simply
by the door being closed sharply, and such as to deform intermediate portion 5. In
fact, when such external force is applied, device 18 is free to move, inside cavity
9, with respect to portion 5, upon the external force exceeding the elastic load imparted
by device 28. In handle 1 described, elastic device 28 therefore makes detecting device
18 functionally unaffected by any deformation of intermediate portion 5, which may
therefore be made of any, even flexible or easily deformable material.
[0022] In the absence of external force, device 18 is maintained by elastic device 28 in
a stable condition, thus preventing any relative movement resulting in vibration or
undesired acoustic emissions.
[0023] Forming elastic device 28 in one piece with cover 35 closing end opening 11 of insertion
of detecting device 18 reduces the number of component parts, makes assembly faster,
and improves the stability of the handle, by the component parts being interconnected
so that each maintains its original position.
[0024] Cavity 13 and the particular cover 14, on the one hand, permit direct access to detecting
device 18 to connect device 18 electrically to wiring 21, if necessary, once detecting
device 18 is inserted inside intermediate portion 5 of lever 3, and, on the other,
define the wiring conduit while greatly simplifying formation of the lever and assembly
of the handle.
[0025] Clearly, changes may be made to handle 1 as described herein without, however, departing
from the scope of the present invention as defined by the appended claims. In particular,
a different elastic forcing device may be provided and located in a different position
from the one shown by way of example.
[0026] End portion 23 of device 18 may be connected differently to lever 3, even by means
of a further elastic retaining device identical with or differing from the one described.
[0027] Moreover, detecting device 18 may have no outer casing 19, and elastic device 28
and the anchoring device may act directly on the sensor or detecting antenna 20.
