1. Field of the Invention
Embodiments of the present invention relate to a raising device for raising or opening a closure panel. More particularly, embodiments of the present invention relate to systems and methods for raising or opening a closure panel after the closure panel has been unlocked, where the closure panel can include but is not limited to a rear flip glass, decklid, door of a vehicle, or hood of a vehicle.
2. Background Information
In general a closure panel of a vehicle, like a rear flip glass, decklid, or hood, can be locked to the body of the vehicle by a raising locking device. This locking device may comprise a locking striker secured to one of the body and the closure panel and a catch with a hook part secured to the other of the body and the closure panel. For locking the closure panel, the catch can be moved to a first position at which the hook part is in hook engagement with the locking striker. For unlocking the closure panel the catch can be moved to a second position at which the hook part is in disengagement with the locking striker. The catch is retained in the first position by a pivoted pawl wherein a shoulder of the pawl is in engagement with a corresponding portion of the catch. The catch is coupled to a spring, which is preloaded when the catch is in its first position. For unlocking the closure panel the pawl rotates such that the retaining shoulder of the pawl disengages the catch allowing the catch to move in the second position, wherein with the help of the urging force of the spring the catch pushes the locking striker, thereby raising or opening the closure panel from the body (see e.g., U.S. Pat. No. 5,020,838). In the resulting clearance between closure panel and body, fingers of a user can grasp to open the closure panel completely.
The raising force of the spring that is required to raise or open the closure panel by a predetermined amount varies in particular with the weight of the closure panel. Therefore, a locking device with a spring providing a specific raising force has to be designed for each closure panel having a specific weight. This is time consuming and quite expensive.
In view of the foregoing, it can be appreciated that a substantial need exists for systems and methods that can advantageously raise or open a closure panel without regard to the weight of the closure panel.
It is, therefore, an object of the present invention to provide a raising device, like a raising locking device or pop-up striker, which can easily be adapted to a closure panel with a particular weight and to a desired clearance eliminating the need to design different raising devices adapted to different weights of closure panels or different desired clearances.
The raising device for raising or opening a closure panel, in particular a rear flip glass, decklid, door or hood of a vehicle, after the closure panel has been unlocked, comprises, according to an embodiment of the invention, a raising lever movably supported by a base frame, a spring having one part coupled to the raising lever for providing a raising force, and securing means associated with the base frame for securing another part of the spring to secure the spring in different spring conditions wherein each spring condition yields a different spring force and a raising force.
The spring can be a pressure or tension spring wherein in various spring conditions the spring is expanded or compressed to different degrees.
Alternatively, the spring can be a torsion spring wherein in various spring conditions the spring is bent to different torsional degrees.
The raising lever is preferentially pivotably mounted to the base frame.
It is further preferred that the raising lever is mounted on a bar providing a pivot axis of the raising lever, wherein the spring is coiled around the bar and wherein leg portions of the spring are secured to the base frame by the securing means to secure the spring in one of the different spring conditions. Spaced securing elements providing securing means can be disposed in the base frame so that at least one leg portion of the spring can be secured to at least one of the securing elements providing one of the different spring conditions.
Spaced securing elements can be disposed in the base frame so that at least one end portion of the spring can be secured to at least one of the securing elements providing one of the different spring conditions.
The securing elements can comprise spaced L-shaped projections formed in the base frame wherein a leg portion of the spring can be hooked on one of the projections to secure the spring in one of the different spring conditions.
In a preferred embodiment, a stop is attached to the base frame to restrict movement of the raising lever. The spring can be preloaded so as to bias the raising lever against the stop.
The raising device can be a raising locking device or a pop-up striker, and the raising lever can be a catch means of the locking device.
Furthermore, the present invention provides a vehicle having a closure panel, like a rear flip glass, decklid, door or hood, pivoted to a body of the vehicle for closing and opening of the body comprising a raising device according to the present invention for raising or opening the closure panel, after it has been unlocked.
In a preferred embodiment, the vehicle comprises a raising locking device being the raising device and a catch means being the raising lever provided with a hook part, the raising locking device comprising a locking striker, the catch means being movable between a first position at which the hook part is an engagement with the locking striker and a second position at which the hook part is in disengagement with the locking striker and at which the catch means pushes the locking striker to raise the closure panel from the body, wherein the catch means is attached to one of the closure panel and the body and the locking striker is attached to the other of the closure panel and the body.
Before one or more embodiments of the invention are described in detail, one skilled in the art will appreciate that the invention is not limited in its application to the details of construction, the arrangements of components, and the arrangement of steps set forth in the following detailed description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.
As an alternative to
The locking device 1 comprises a base frame 11 attached to the body 7 (see
The catch 9 is pivoted to the base frame 11 by a pivot bar 17 with axis 19 wherein the catch 9 is disposed substantially in a center portion of a length of the bar 17 and wherein end portions 31, 33 of the bar 17 are rotatably supported by the base frame 11. In a first position, schematically shown in
The location of the catch 9 on the bar 17 defines two portions 35, 37 of the bar 17, a first portion 35 on one side and a second portion 37 on the other side of the catch 9, wherein the spring 13 is coiled around both portions 35, 37 and surrounds the catch 9 wherein a U-shaped center portion 25 of the spring 13 acts against a side face 26 of catch 9.
The base frame 11 comprises two substantially rectangular openings 80, 82. Each opening 80, 82 has two L-shaped projections 84, 86 or 88, 90, respectively, such that a bottom edge 92a, 92d, respectively, of each opening 80, 82 and an upper edge 92b, 92c, 92e, 92f, respectively, of each projection provide three pairs of support places 92a, 92b, 92c and 92d, 92e, 92f, respectively. Leg portions 21, 23 of the spring 13 are aligned substantially perpendicularly to the pivot axis 19 and are adapted to be engaged in any two of the support places 92a, 92b, 92c and 92d, 92e, 92f (securing means) of the base frame 11, i.e., each of the leg portions 21, 23 can be placed either on one of the bottom edges of the rectangles openings or on one of the upper edges of the projections.
The pawl 39 holds the catch 9 in its first position locking the rear flip glass 3 to the body 7 (
The width of the clearance generally depends on the relation between the spring force of the spring 13 and the weight of the rear flip glass 3. The spring force can easily be varied by placing the leg portions 21, 23 of the spring 13 at different support places 92a . . . 92f of the base frame 11. As is shown in
The actuator 48 can be driven electrically, pneumatically, or mechanically. In a preferred embodiment, the actuator 48 is remote-controlled.
With the securing means 92a . . . 92f in
The base frame 11 has a substantially rectangular shape and forms a casing for enclosing catch 9, pawl 39, and spring 13. The base frame 11 of the raising locking device 1 according to
The raising device can be attached to the body of the vehicle or to the closure panel. That is, the base frame containing catch, spring and pawl and the actuator of the raising locking device can be attached to one of the body and the closure panel, and the locking striker can be attached to the other of the body and the closure panel.
The spring according to
A spring condition is defined by the degree of expansion, compression or bending (torsion angle) of the spring. In the embodiment illustrated in
In the above-described embodiment, the raising locking device locks and unlocks the closure panel and provides a pop-up movement relative to the body of the vehicle. Alternatively, as illustrated in
The pop-up striker 70 (see
A pop-up striker can be attached to a closure panel of a vehicle. Alternatively, it could be attached to the body of the vehicle. The spring is preloaded so as to bias the raising lever against a corresponding portion of the body when the closure panel is locked. When the closure panel is unlocked by the locking device, the raising lever pushes against a corresponding portion of the body or closure panel and raises the closure panel from the body.
In another embodiment, the pop-up striker comprises a raising lever pivoted to a base frame and coupled to a tension or pressure spring. One end of the spring is attached to the raising lever and the other end of the spring is secured to one of different possible securing places within a base frame by securing means for holding the spring in a desired spring condition. Depending on the securing place chosen, the spring is set in a differently expanded or compressed condition in a closed condition of the closure panel leading to different spring conditions and spring forces of the spring, thereby providing different raising forces, when the closure panel is unlocked. By attaching the other end of the spring to one of different securing places the spring condition and thus the raising force of the pop-up striker can be adapted e.g. to a particular closure panel weight.
The raising device, i.e., the pop-up striker 70 or the raising locking device 1, can comprise a stop 60 (
If the spring force of the spring is too large, the clearance between the closure panel and the body might be large enough, but in use, it can be difficult to close and lock the closure panel easily. On the other hand, if the spring force is too small, the closure panel can easily be closed and locked, but the clearance achieved between the closure panel and the body can be too small, when the closure panel is unlocked. To overcome this problem, heretofore for each particular closure panel with a particular weight a raising device, i.e., raising locking device or pop-up striker, with a spring providing a particularly determined spring force had to be designed. In contrast, the raising device according to the invention can easily be adapted to the weight of a particular closure panel by securing the spring by the securing means in a properly chosen spring condition providing the required raising force. Thus, the raising device according to the invention can be used with closure panels having different weights eliminating the need of substituting the spring.
