Abstract:
An outside handle of a vehicle that releases a door latch, including a slot that includes a rotatable flap that sits flush against an outer panel of the vehicle in a closed position. The rotation of the flap provides an opening to an inside of the handle in an open position. The handle includes a rotating lever behind the outer panel, and a lock rod attached to the rotating lever. Downward rotation of the lever moves the rod downward, and the downward motion of the rod then triggers the latch.

Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
       [0001]    Exemplary aspects of the present invention relate to a hidden, flush mounted outside handle for opening a door of a vehicle. 
       SUMMARY OF THE INVENTION 
       [0002]    The present application relates to a door handle of a vehicle with a flush and aerodynamic appearance by placing the mechanical pieces behind an outer panel and keeping them hidden. The functionality of the handle is not compromised, and a user is able to grip the handle in a similar motion to the current outside handle design. 
         [0003]    An outside handle of a vehicle that releases a door latch, includes a slot that includes a rotatable flap that sits flush against an outer panel of the vehicle in a closed position. The rotation of the flap provides an opening to an inside of the handle in an open position. The handle includes a rotating lever behind the outer panel, and a lock rod attached to the rotating lever. Downward rotation of the lever moves the rod downward, and the downward motion of the rod then triggers the latch.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0010]    Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views. Further, as used herein, the words “a,” “an” and the like generally carry a meaning of “one or more,” unless stated otherwise. 
         [0011]      FIGS. 1-5  depict various aspects of a hidden door handle for a vehicle. Here a vehicle refers to a land vehicle exemplified by an automobile. However, the present disclosure is also applicable to any similar type vehicle, such as but not limited to, a sport utility vehicle, a pickup truck, a commercial vehicle, aircraft, boat, or the like. 
         [0012]      FIG. 1  displays an isometric bottom view of a hidden door handle assembly.  FIG. 5  illustrates a side view of this assembly.  FIG. 2  illustrates a top flap  1  disposed in an outer door panel  11 . The flap  1  has a generally rectangular shape, but is not limited to such a shape. 
         [0013]    Behind the top flap  1  is an interior space defined partially by the flap and a case  6 . Shown in  FIG. 5 , the case  6  has a back surface opposite to the flap  1 . As shown in the figures, the case  6  encloses the operational parts of the handle assembly. Aside from aiding in mounting and supporting the components, the case  6  aids the user to feel more comfortable inserting his or her hand inside the door. 
         [0014]    Attached to the case is a rod  10  which extends between side surfaces of the case  6 . The rod  10  traverses a width of the case  6  and is located at the top of the case  6 . The rod  10  is attached to the flap  1 , so that the flap  1  is rotatable about the rod  10 . The rod  10  defines an axis of rotation for the flap  1 . When pushed from the outside, the top flap  1  rotates around the rod  10 , causing the flap  1  to enter the interior space of the case  6 . 
         [0015]    A pivot  7  is attached to a lever  2 . The pivot  7  is located at a middle portion of the side surfaces of the case  6 . The pivot  7  defines an axis of rotation for the lever  2 . That is, the lever  2  is rotatable about the pivot  7 . The pivot  7  is illustrated as interfacing with the case  6  on one side but a second pivot (not illustrated) may also be provided to the opposite side of the case  6 . 
         [0016]    Shown in  FIG. 1 , the lever  2  has two portions. A first portion of the lever  2  is generally rectangular and is pivotable around the pivot  7 . The second portion of the lever  2  is generally triangular and extends from an end of the first portion. The second portion is formed at an angle relative to the first portion. The angle being approximately 90 degrees in the figures. A lock rod  9  is attached to the lever  2  at the second portion. The lock rod  9  is attached to a latching mechanism or latch of the door (not illustrated), and sufficient movement of the lock rod  9  opens the latching mechanism, thereby allowing the door to be opened. The lock rod  9  is attached to the lever  2  by a rod clip  8  and is able to rotate freely. 
         [0017]      FIG. 2  illustrates an exterior view of the assembly including the flap  1  in a closed position. Here, an outer surface of the flap  1  sits flush with the outer door panel  11 . The top flap  1  is the only part of the handle that is seen from the exterior and fits properly into a slot made in the outer panel  11  of the door. This is what creates the flush appearance to the exterior of the vehicle. 
         [0018]      FIG. 3  illustrates different positions and motions of the top flap  1  and the lever  2  during operation.  FIG. 3  illustrates three positions of the lever  2 . The topmost position of the lever  2  is a rest or beginning position. When the lever  2  is rotated 34 degrees (at point  14 ), the lock lever  9  is moved a sufficient amount so that the latch is triggered. At point  15 , the lever  2  is at a position in which the user has fully clamped the handle and where the lever  2  would touch the outer panel  11  of the door.  FIG. 3  also illustrates the top flap  1  in two positions. The first is rightmost in  FIG. 3 , and corresponds to the flap  1  being in the closed position. The second is position  13  which corresponds to the flap  1  being in the open position. The open position  13  of the top flap  1  allows room for a 95 percentile hand to fit inside the interior space of the case  6 . 
         [0019]    Described above, the top flap  1  and the lever  2  each pivot on a rod  10  and pivot  7 , respectively. Springs are provided to bias the flap  1  and the lever  2  back toward their initial positions, respectively, as shown in  FIG. 5 . To prevent the user&#39;s hand from getting caught inside the handle, the closing speed of the flap  1  is controlled by a one way damper  4 . The one way damper  4  is mounted to the case  6  and meshes with a gear  5  that is mounted on the pivoting rod  10 . The one way damper  4  is allowed to move freely in a first direction (e.g. clockwise) and adds resistance in a second direction (e.g. counter clockwise). Accordingly, the top flap  1  closes slowly. If needed, a spring (not illustrated) may be mounted outside of the case  6  and rest on the portion of the lever  2  that sticks out past the case  6  and the inside of the outer door panel  11 . This spring biases the lever  2  towards the topmost, rest position as shown in  FIGS. 3 and 5 . 
         [0020]      FIG. 4  schematically illustrates a user&#39;s hand  12  inside the handle. Here, the flap  1  is in the open position ( 13  in  FIG. 3 ) and the hand  12  is operating the lever  2  to trigger the latch. The position of the lever  2  in  FIG. 4  is similar to position  14  illustrated in  FIG. 3 , which will cause the lock lever  9  to open the latching mechanism.  FIG. 4  illustrates the first two parts of the user&#39;s fingers on the user&#39;s hand  12  operating the handle, which is a common gripping motion. 
         [0021]    Described above, the hidden handle assembly of the present application has several advantages. The first being a sleek and aerodynamic appearance from the outside of the vehicle. Further, the handle operates in a similar pulling motion that is customary with typical door handles. Therefore, the user gets the benefit of the exterior appearance and customary motion. Moreover, safety is considered by damping the motion of the top flap so as to not pinch a user&#39;s hand. 
         [0022]    Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
