Abstract
A lid opener for use in a vehicle comprises a base member secured to a vehicle body. A control lever is pivotally connected to the base member. A rear portion of the control lever is connected through a wire to a latch mechanism of a lid member. The control lever is capable of canceling a latched condition of the latch mechanism when pivoted in a normal direction from a rest position to a work position. A spring is used for biasing the control lever to assume the rest position. A first stopper structure includes the rear portion of the control lever and a part of the base member. The rear portion is kept in contact with the part of the base member when the control lever assumes the rest position. A second stopper structure includes a part of the control lever and a stopper member which is defined by either one of the vehicle floor and the base member. The part of the control lever is brought into abutment with the stopper member when, upon receiving a marked stress, the control lever is pivoted from the rest position in a direction opposite to the normal direction.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates in general to lid openers for use in motor vehicles for remotely controlling or unlatching a lid, such as a filler cap, a trunk lid or the like. More specifically, the present invention relates to the lid openers of a double lever type having two control levers for remotely controlling or unlatching two lid members respectively.
2. Description of the Prior Art
In order to clarify the task of the present invention, one conventional lid opener will be briefly described with reference to
FIGS. 10 and 11
of the accompanying drawings.
As is seen from
FIG. 10
, the lid opener
100
shown is of a double lever type. The lid opener
100
is arranged on a vehicle floor “F”, more specifically, on a base member
102
tightly held by a cross member
104
of the vehicle body.
The lid opener
100
comprises two, viz., longer and shorter control levers
106
and
108
which are pivotally disposed about a common shaft
110
held by the base member
102
. The two control levers
106
and
108
have rear ends
106
a
and
108
a
from which respective wires
112
(
114
) extend to respective latch mechanisms of a trunk lid and a filler cap. The two control levers
106
and
108
are biased to assume horizontal rest positions by respective biasing springs
116
and
118
. When the longer control lever
106
is pulled up against the biasing force of the spring
116
, the wire
112
is driven in a direction to cancel a latched condition of the latch mechanism of the trunk lid. Upon this, the trunk lid becomes unlatched and thus can be opened. While, when the shorter control lever
108
is pulled up against the force of the spring
118
, the wire
114
is pulled to unlatch the filler cap.
For ease with which the two control levers
106
and
108
are manipulated by a driver, such lid opener
100
is arranged just beside the driver's seat, that is, in a limited space defined between the driver's seat and the driver's door.
However, due to inherency originating from the position where the lid opener
100
is located, it often happens that the lid opener
100
is strongly stepped on by the driver at his or her ingress and egress into and from the vehicle cabin, which tends to cause damages of the control levers
106
and
108
.
For eliminating such drawbacks, various measures have been hitherto proposed, which are, for example, covering the lid opener
100
with a cover member, using a much thicker metal plate as the material of the control levers
106
and
108
, locating the lid opener
100
away from such limited space, etc.,. However, even these measures have failed to provide users with satisfaction. In fact, such measures tend to induce a bulky, costly and/or ill-handy lid opener.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a lid opener which is free of the above-mentioned drawbacks.
According to the present invention, there is provided a lid opener which is so constructed that when a marked stress is applied to a control lever of the lid opener due to accidental stepping by a passenger, the control lever becomes supported by at least three supporting points thereby minimizing the force actually applied to each point. Thus, undesired deformation and damage of the control lever is suppressed.
According to a first aspect of the present invention, there is provided a lid opener for use in a vehicle having a body and a floor. The lid opener comprises a base member adapted to be secured to the body; a control lever pivotally connected to the base member, the control lever including front and rear portions which are defined with respect to the pivoted portion, the rear portion being connected through a power transmitting member to a latch mechanism of a lid member, the control lever being capable of canceling a latched condition of the latch mechanism when pivoted in a normal direction from a rest position to a work position; biasing means for biasing the control lever to assume the rest position; a first stopper structure including the rear portion of the control lever and a part of the base member, the rear portion being kept in contact with the part of the base member when the control lever assumes the rest position; and a second stopper structure including a part of the control lever and a stopper member which is defined by either one of the vehicle floor and the base member, the part of the control lever being brought into abutment with the stopper member when, upon receiving a marked stress, the control lever is pivoted from the rest position in a direction opposite to the normal direction.
According to a second aspect of the present invention, there is provided a lid opener unit for use in a vehicle. The vehicle has a hollow cross member mounted on a vehicle floor, and the hollow cross member has in a wall thereof an opening. The lid opener unit includes a base member installed in and secured to the hollow cross member near the opening; a control lever pivotally connected to the base member, the control lever including front and rear portions which are defined with respect to the pivoted portion, the front portion being exposed to the outside through the opening, the rear portion being connected through a power transmitting member to a latch mechanism of a lid member, the control lever being capable of canceling a latched condition of the latch mechanism when pivoted in a normal direction from a rest position to a work position; biasing means for biasing the control lever in a direction to assume the rest position; a first stopper structure including the rear portion of the control lever and a part of the base member, the rear portion being kept in contact with the part of the base member when the control lever assumes the rest position; and a second stopper structure including a part of the control lever and a stopper member which is defined by either one of the vehicle floor and the base member, the part of the control lever being brought into abutment with the stopper member when, upon receiving a marked stress, the control lever is pivoted from the rest position in a direction opposite to the normal direction.

DETAILED DESCRIPTION OF THE EMBODIMENTS
Referring to
FIGS. 1
to
5
, there is shown a double lever type lid opener
100
A which is a first embodiment of the present invention.
As is seen from
FIG. 1
, a major section of the lid opener
100
A is installed in a hollow cross member
10
of a vehicle body at a position between a side sill
12
and a driver's seat
14
.
In the following, directional terms, such as “right”, “left”, “front”, “rear”, “rightward”, “leftward”, “forward”, “rearward” and the like are to be understood with respect to the driver sitting on the seat
14
.
Although not shown in the drawing, a front right door (viz., driver's door) is arranged on the side sill
12
, which closes and opens a door opening defined above the side sill
12
. In the illustrated embodiment, a front portion of the driver's seat
14
is disposed on the cross member
10
through a pair of seat sliders
16
. Denoted by reference “F” is a floor of the vehicle.
The hollow cross member
10
is formed at its front wall with a rectangular opening
18
through which front portions of the control levers
20
and
22
are projected forwardly. Thus, a driver sitting on the seat
14
can easily handle the control levers
20
and
22
only by extending down his or her right hand toward the levers
20
and
22
. Denoted by numeral
24
is a base member of the lid opener
10
A, which is secured via a bolt
26
to the cross member
10
for supporting essential parts of the double lever type lid opener
100
A.
As is seen from
FIGS. 2 and 3
, the lid opener
100
A comprises two, viz., longer and shorter control levers
20
and
22
which are pivotally disposed about a common pivot shaft
28
which is held by the base member
24
. The levers
20
and
22
and the base member
24
are constructed of reinforced plastics, such as reinforced polyacetal resin or the like. However, if desired, these members
20
,
22
and
24
may be constructed of metals. For increased strength, each lever
20
or
22
is shaped to have a generally L-shaped cross section. Furthermore, each lever
20
or
22
has at the front exposed part a convexly curved upper edge (no numeral).
The base member
24
comprises a front flat part
24
a
bolted to the front wall of the cross member
10
, a middle flat part
24
b
extending rearward from the front flat part
24
a,
an upper cover part
24
c
extending laterally from an upper end of the middle flat part
24
b
and an inclined rear part
24
d.
The common shaft
28
is held by the middle flat part
24
b.
The middle flat part
24
b
is formed at its lower portion with a stopper projection
24
e
which extends rightward in
FIG. 1
, that is, toward the shorter control lever
22
. The shape of the stopper projection
24
e
may be imaged from the drawing of FIG.
8
.
As is seen from
FIG. 3
, the longer control lever
20
has a recess
20
x
in which the shorter control lever
22
is snugly received.
As is seen from
FIG. 2
, the longer control lever
20
has at a front end a thinner grip portion
20
a
which is shaped to be easily gripped by an operator (viz., driver). A rear end
20
b
of the longer control lever
20
is connected to the inclined rear part
24
d
of the base member
24
through a biasing spring
30
. Due the force of this spring
30
, the longer control lever
20
is biased to assume its horizontal rest position as illustrated by a solid line in
FIG. 2. A
wire connector
20
c
is provided on the rear end
20
b
of the control lever
20
, which holds one end of a wire
32
extending from a latch mechanism of a trunk lid. A guide member
34
is pivotally held by the inclined rear part
24
d
of the base member
24
, through which the wire
32
passes. When thus the longer control lever
20
is pulled up against the force of the biasing spring
30
, the wire
32
is driven in a direction to cancel a latched condition of the latch mechanism of the trunk lid. Upon this, the trunk lid becomes unlatched and thus can be opened. As will be described in detail hereinafter, when the longer control lever
20
is pulled up to its uppermost position as illustrated by a phantom line in
FIG. 2
, the wire connector
20
c
of the lever
20
abuts against the stopper projection
24
e
of the base member
24
. That is, the stopper projection
24
e
functions to suppress excessive upward pivoting of the longer control lever
20
.
It is now to be noted that the shorter control lever
22
has substantially the same construction as the above-mentioned longer control lever
20
except that in the shorter control lever
22
, a wire connected to the rear end of the lever
22
extends to a latch mechanism of a filler cap. That is, when the shorter control lever
22
is pulled up against the force of a corresponding biasing spring, the latch mechanism of the filler cap becomes unlatched ant thus the filler cap can be opened. Also in this case, the stopper projection
24
e
functions to suppress excessive upward pivoting of the shorter control lever
22
.
In the first embodiment
100
A, the following measures are further employed.
That is, as is seen from
FIG. 2
, front and rear stopper portions
20
A and
20
B are defined at front and rear portions of the control lever
20
. The front stopper portion
20
A is constituted by a downwardly protruded part of the front portion of the lever
20
, and the rear stopper portion
20
B is constituted by an upwardly protruded part of the rear portion of the lever
20
. That is, when the longer control lever
20
assumes the horizontal rest position as shown in
FIG. 2
, the rear stopper portion
20
B abuts against the upper cover part
24
c
of the base member
24
leaving a predetermined space “Sa” between the front stopper portion
20
A and the vehicle floor “F”.
It is to be noted that the thickness of the space “Sa” is determined smaller than a moved distance which is exhibited by the front stopper portion
20
A when the latter is subjected to a maximum resilient deformation, that is, when the lever
20
is strongly stepped by a passenger (viz., driver). Preferably, the thickness of the space “Sa” is smaller than about 5 mm.
It is to be noted that the above-mentioned measures of the longer control lever
20
are not needed by the shorter control lever
22
. However, if desired, such measures may be applied to the shorter one.
In the following, operation will be described with the aid of the drawings.
For ease of understanding, the description will be commenced with respect to a rest condition of the lid opener
100
A wherein both the longer and shorter control levers
20
and
22
assume their horizontal rest positions, as is seen from FIG.
2
.
When the longer control lever
20
is pulled up against the force of the spring
30
, the wire
32
is driven in a direction to cancel the latched condition of the latch mechanism of the trunk lid. Thus, the trunk lid becomes unlatched and thus can be opened. As is mentioned hereinabove, due to provision of the stopper projection
24
e
against which the wire connector
20
c
of the lever
20
can abut, the upper work position of the longer control lever
20
is assured. When then the longer control lever
20
is released, the lever
20
is returned to the horizontal rest position of
FIG. 2
due to the force of the spring
30
.
When the shorter control lever
22
is pulled up, the latched condition of the filler cap becomes canceled and thus the filler cap can be opened, like in the case of the above-mentioned trunk lid.
When, with the lid opener
100
A assuming the rest condition, a remarkable force “P” is suddenly applied to the exposed front portions of the longer and shorter control levers
20
and
22
due to accidental stepping by a driver's shoe as is seen from
FIG. 5
, the longer control lever
20
is pressed down bringing the front stopper portion
20
A thereof into abutment with the vehicle floor “F” while keeping the abutment of the rear stopper portion
20
B with the upper cover part
24
c
of the base member
24
. During this, the longer control lever
20
is subjected to a resilient deformation by a degree of the thickness of the space “Sa”, and upon abutment of the front stopper portion
20
A with the vehicle floor “F”, the force “P” applied to the longer control lever
20
becomes supported by three supporting points, which are a first supporting point “P
1
” where the front stopper portion
20
A contacts the vehicle floor “F”, a second supporting point “P
2
” where the rear stopper portion
20
B contacts the upper cover part
24
c
of the base member
24
and a third supporting point “P
3
” where the longer control lever
20
is disposed about the pivot shaft
28
. That is, the shock “P” applied to the longer control lever
20
is supported by the three points minimizing the force actually applied to each supporting point “P
1
”, “P
2
” or “P
3
”. Thus, undesired deformation and damage of the longer control lever
20
are suppressed.
It is to be noted that when both the longer and shorter control levers
20
and
22
are stepped by the driver's shoe, the longer control lever
20
protects the shorter control lever
22
by carrying out the above-mentioned self-supporting function.
Referring to
FIGS. 6
to
9
, there is shown a double lever type lid opener
100
B which is a second embodiment of the present invention.
The lid opener
100
B of this embodiment is similar to that of the above-mentioned first embodiment
100
A. Thus, detailed explanation will be directed to only parts or portions which are different from those of the first embodiment
100
A.
As is seen from
FIGS. 6 and 8
, like in the first embodiment
10
A, the lid opener
100
B of this second embodiment comprises longer and shorter control levers
20
′ and
22
′ which are pivotally disposed about a common pivot shaft
28
. Each control lever
20
′ or
22
′ has at the front exposed part a convexly curved upper edge. The pivot shaft
28
is held by a base member
24
′ which is constructed of a metal. The base member
24
′ comprises a front flat part
24
′
a
secured to the cross member
10
, a middle flat part
24
′
b
extending rearward from the front flat part
24
′
a,
an upper cover part
24
′
c
extending laterally from an upper end of the middle flat part
24
′
b
and an inclined rear part
24
'
d.
The middle flat part
24
′
b
is formed at its lower portion with a stopper projection
24
′
e
which extends toward the shorter control lever
22
′. The shape of the stopper projection
24
′
e
may be seen from FIG.
9
.
As is seen from
FIG. 6
, the longer control lever
20
′ has near the wire connector
20
′
c
a forward projection
36
which abuts against the stopper projection
24
′
e
when the lever
20
′ is pivoted up to the upper work position. A biasing spring
30
extends between a rear end
20
′
b
of the longer control lever
20
′ and the middle flat part
24
′
b.
From a wire connector
20
′
c
provided by the rear end
20
′
b,
there extends a wire
32
to a latch mechanism of a trunk lid. A guide member
34
is pivotally held by the inclined rear part
24
′
d
of the base member
24
′, through which the wire
32
extends. Due to the force of the biasing spring
30
, the longer control lever
20
′ is biased to assume the horizontal rest position. The shorter control lever
22
′ has substantially the same construction as the longer control lever
20
′ except that in the shorter control lever
22
′, a wire connected to the rear end of the lever
22
′ extends to a latch mechanism of a filler cap.
In the second embodiment
100
B, the following measures are further employed.
That is, as is seen from
FIG. 6
, the longer control lever
20
′ is formed at a rear portion thereof with a rear stopper portion
20
′B which is contactable with the upper cover part
24
′
c
of the base member
24
′.
Furthermore, as is seen from
FIGS. 6 and 7
, the longer control lever
20
′ is formed near the pivot shaft
28
with a middle stopper portion
20
′A which projects downward. When the longer control lever
20
′ assumes the horizontal rest position as shown in
FIGS. 6 and 7
, the rear stopper portion
20
B abuts against the upper cover part
24
′
c
of the base member
24
′ leaving a predetermined space “Sb” between the middle stopper portion
20
′A and the stopper projection
24
′
e.
The thickness of the space “Sb” is determined smaller than a moved distance which is exhibited by the middle stopper portion
20
′A when the latter is subjected to a maximum resilient deformation, that is, when the lever
20
′ is strongly stepped by a passenger (viz., driver). Preferably, the thickness of the space “Sb” is smaller about 1 mm.
It is to be noted that the above-mentioned measures of the longer control lever
20
′ are not needed by the shorter control lever
22
′. However, if desired, such measures may be applied to the shorter one.
When, with the lid opener
100
B assuming a rest condition as shown in
FIG. 6
, the longer control lever
20
is pulled up against the force of the spring
30
, the wire
32
is driven in a direction to cancel the latched condition of the trunk lid. Due to provision of the stopper projection
24
′
e
against which the forward projection
36
of the lever
20
′ can abut, the upper position of the longer control lever
20
′ is assured. When the longer control lever
20
′ is released, the lever
20
′ is returned to the horizontal rest position of
FIG. 6
due to the force of the spring
30
. When the shorter control lever
22
′ is pulled up, the latched condition of the filler cap becomes canceled and thus the filler cap can be opened, like in the case of the above-mentioned trunk lid.
When, with the lid opener
100
B assuming the rest condition, a remarkable force is suddenly applied to the exposed front portions of the longer and shorter control levers
20
′ and
22
′ due to accidental stepping by a driver's shoe, the longer control lever
20
′ is pressed down bringing the middle stopper portion
20
′A thereof into abutment with the stopper projection
24
′
e
of the base member
24
′ while keeping the abutment of the rear stopper portion
20
′B with the upper cover part
24
′
c
of base member
24
′. During this, the longer control lever
20
′ is subjected to a resilient deformation by a degree of the thickness of the space “Sb”, and upon abutment of the middle stopper portion
20
′A with the stopper projection
24
′
e,
the force applied to the longer control lever
20
′ becomes supported by three supporting points, which are a first supporting point “P′
1
” where the middle stopper portion
20
′A″ contacts the stopper projection
24
′
e
of the base member
24
′, a second supporting point “P′
2
” where the rear stopper portion
20
′B contacts the upper cover part
24
′
c
of the base member
24
′ and a third supporting point “P′
3
” where the longer control lever
20
′ is disposed about the pivot shaft
28
. That is, like in the case of the above-mentioned first embodiment
100
A, the shock applied to the longer control lever
20
′ is supported by the three points minimizing the force actually applied to each supporting point “P′
1
”, “P′
2
” or “P′
3
”. Thus, undesired deformation and damage of the longer control lever
20
′ are suppressed.
It is to be noted that even when both the longer and shorter control levers
20
′ and
22
′ are stepped by the driver's shoe, the longer control lever
20
′ protects the shorter control lever
22
′ by carrying out the above-mentioned self-supporting function.

- 2. A lid opener as claimed in claim 1, in which said engagement part of said control lever is normally spaced from said stopper member by a predetermined distance when said control lever assumes said rest position and is undistorted by the application of a marked stress.
- 3. A lid opener as claimed in claim 2, in which said predetermined distance is a distance traveled by the engagement part of said control lever when said control lever is subjected to the application of the marked stress at the front portion of said control lever and said control lever is changed from an undeformed state to one wherein a maximum resilient deformation has occurred and wherein the engagement part of the control lever is forced into engagement with the stopper member which is defined by either one of the vehicle floor and said base member.
- 4. A lid opener as claimed in claim 3, in which said engagement part of said control lever is defined at said front portion of said control lever and in which said stopper member is the vehicle floor.
- 5. A lid opener as claimed in claim 4, in which said predetermined distance is smaller than about 5 mm.
- 6. A lid opener as claimed in claim 3, in which said engagement part of said control lever is defined near the pivoted end portion of the control lever and in which said stopper member is a stopper structure defined by said base member.
- 7. A lid opener as claimed in claim 1, further comprising a third stopper structure which includes another part of said base member and a given part of said rear portion of said control lever, said given part being brought into abutment with said another part of said base member when said control lever is pivoted in the normal direction from said rest position to the work position.
- 8. A lid opener as claimed in claim 7, in which said given part of said rear portion of the control lever constitutes a connector to which one end of said power transmitting member is connected.
- 9. A lid opener as claimed in claim 7, in which said given part of said rear portion of the control lever is projected downward.
- 10. A lid opener as claimed in claim 1, further comprising another control lever which is pivotally supported on said base member by the pivot shaft on which the first said control lever is pivotally supported, said another control lever having a rear portion connected through another power transmitting member to a latch mechanism of another lid member.
- 11. A lid opener as claimed in claim 10, in which said another control lever is received in a recess formed in the the first said control lever.
- 12. In a vehicle having a hollow cross member mounted on a vehicle floor, said hollow cross member having an opening in a wall portion thereof,a lid opener unit comprising: a base member installed in and secured to said hollow cross member near said opening; a control lever pivotally connected to said base member, said control lever including front and rear portions which are respectively distal and proximate with respect to a pivoted end portion thereof, said front portion extending out through said opening so as to extend over the floor, said rear portion being connected through a power transmitting member to a latch mechanism of a lid member, said control lever canceling a latched condition of said latch mechanism when pivoted in a first direction from a rest position to a latch release position; biasing means for biasing said control lever in a direction to assume said rest position; a first stopper structure including said rear portion of said control lever and a stopper part of said base member, said rear portion contacting said stopper part of the base member when said control lever assumes said rest position to prevent pivotal movement of said control lever in a second direction which is opposite the first direction; and a second stopper structure including an engaging part of said control lever and a normally spaced stopper member which is defined by either one of the vehicle floor and said base member, the engaging part of said control lever being brought into abutment with said stopper member only when said control lever is resiliently distorted from the rest position in the second direction by the application of a marked stress which is applied to said front portion.
