Title: Door handle assembly

Description:
FIELD OF THE DISCLOSURE 
     This disclosure is directed generally to door handles and, more particularly, to door handle assemblies. 
     BACKGROUND 
     A door handle assembly is, generally, used in vehicles to secure or lock a door of the vehicle. For aesthetic appeal of exteriors and interiors, nowadays, vehicles are provided with flush door handle assemblies. Such a door handle assembly includes a handle that is retractably mounted to the vehicle door such that the handle is flush with a lateral wall of the vehicle door, for example, either on an external surface of the vehicle door or facing a passenger compartment of the vehicle, when not in use or undeployed. The handle may be movable between an undeployed or flush position and a deployed position. In the deployed position, the handle protrudes from the vehicle door for being pulled by a user for unlatching the vehicle door. In other words, the handle is cooperatively coupled to a latching mechanism of the vehicle door to unlatch it when the user further pulls the handle from the deployed position. 
     SUMMARY 
     Door handle assemblies are disclosed, substantially as illustrated by and described in connection with at least one of the figures, as set forth more completely in the claims.

     DETAILED DESCRIPTION 
     Conventional flush door handle assemblies that are deployed in vehicle doors may be mechanically or electrically actuated for moving a handle from a flush position to a deployed position, i.e., from a position in which the handle is aligned with an exterior surface of a vehicle door to a position in which the handle protrudes from the exterior surface of the vehicle door, and vice-versa. Further, the handle may be coupled to a locking component and a latching component that facilitates in unlocking and unlatching a vehicle door, respectively, for opening the vehicle door. 
     The electric motor as deployed in the vehicle door may be cost inefficient, in terms of the cost of the component as well as the cost of sub-components used for its operations, such as a controller and a protection aid. At the same time, use of an electric motor for movement of the handle may involve a complex assembly of various parts which can acquire space and can further add to the cost. In addition, having a separate locking component and latching component may bring in redundancy of components in the vehicle door as well as add to the cost while increasing the weight of the door. Thus, electric motor operated flush handles may turn out to be costly as components, as well as in terms of ownership from a user&#39;s point of view. In addition, upon failure of the electrical motor, the handle may not be movable to the deployed position and, thus, a user may face difficulties in opening the vehicle door. Moreover, housing the electric motor with a lock assembly in the door, of the vehicle, may add on to a weight of the door, and accordingly, to that of the vehicle. 
     Mechanically actuated door handle assemblies may find use in lieu of electrically actuated door handle assemblies, but with their own share of issues. In conventional mechanically actuated door handle assemblies, a push-push assembly may be employed for moving the handle from the flush position to the deployed position and vice-versa. The push-push assembly is positioned substantially parallel to the surface of the door as well as to the handle when the handle is in flush position. An actuator is coupled with the push-push assembly that cooperates with the handle as well as the push-push assembly. Upon actuation of the handle by an operator, the actuator can, in response, actuate the push-push assembly. However, the push-push assembly employed in the conventional door handle assemblies generally have multiple components and involve a complex assemblage of various mechanical components cooperating with each other. In addition, the push-push assembly is also relatively large-sized in comparison to the overall size of the door handle assembly. Such door handle assemblies, therefore, require a considerable space to be accommodated and may not be employable in vehicles having space constraints. At the same time, the complexity of the assembly not only makes the manufacturing cumbersome but can also be prone to high degree of wear and tear, thereby, requiring frequent servicing, repair, or replacement of the parts. Therefore, the conventional mechanically actuated door handle assemblies may not be an adequate replacement for electrically actuated door handle assemblies. 
     Examples of the present subject matter relating to a door handle assembly that inter alia address the abovementioned issues are described herein. The door handle assembly includes a handle movable between the flush or undeployed position to the deployed position by means of mechanical linkages, i.e., using a simplified mechanical assembly instead of utilizing an electric motor. To move the handle from the flush position to the deployed position, the handle is mechanically actuated, such as by pressing the handle or by giving a push to the handle. Thereafter, to move the handle back in the flush position, another actuation, such as a manual pull may be provided. The simplified mechanical assembly provides an adequately operative yet cost-effective door handle assembly. 
     The door handle assembly has a frame for mounting the door handle assembly to the door. The frame may include a housing portion and an exterior surface having a cavity. A handle is disposed in the cavity is pivoted to the frame and is movable between the undeployed position and the deployed position. For example, in the undeployed position, the handle remains inside the cavity and is flush with the exterior surface of the door and, in the deployed position, the handle protrudes from the cavity and beyond the exterior surface of the door. 
     The door handle assembly further includes a push-push assembly operably coupled to the handle. The push-push assembly may be fixedly attached to the frame of the door handle assembly using fasteners, such as a screw. The push-push assembly includes a body, a compression spring housed inside the body, and a pusher operably coupled to the compression spring. The pusher is adapted to translate along a longitudinal axis of the push-push assembly. The longitudinal axis of the push-push assembly can be along a longest dimension of the push-push assembly. 
     According to an aspect of the present subject matter, the push-push assembly is positioned substantially orthogonal to the handle, i.e., the longitudinal axis of the push-push assembly is substantially orthogonal to the longitudinal direction or length of the handle. The longitudinal axis of the push-push assembly can be the axis, as mentioned above, along which the pusher is adapted to translate. Due to the orthogonal positioning of the push-push assembly with respect to the handle, flushness of the handle with respect to the frame of the door handle assembly is directly controlled by the push-push assembly. For instance, the handle is in the flush or undeployed position when the push-push assembly is in a recharged condition, i.e., when the compression spring is in a compressed state, and the handle is in the deployed position when the push-push assembly is in a discharged condition, i.e., the compression spring is in a decompressed state. 
     The door handle assembly also includes a bell crank pivotably mounted to the frame. The bell crank is operably coupled to the handle and the is also in a cooperative coupling with the push-push assembly. The bell crank is a single-piece component and includes a primary profile having a shape that assists in moving the push-push assembly between the discharged and recharged condition. In an example, the pusher of the push-push assembly engages with the primary profile on the bell crank to recharge the push-push assembly. The primary profile formed on the bell crank may have a slanted shape. Further, the primary profile is designed such that maximum height of the primary profile is equal to the distance between a first extreme position of the pusher and a second extreme position of the pusher. The maximum height of the primary profile may be measured from a base of the primary profile of the bell crank to a top end of the primary profile of the bell crank. 
     Initially, the door may be in a locked condition and can be unlocked using any of the known methods, for example, using a remote keyless system or a mechanical key. When the door is unlocked, the handle is in the flush position and the pusher of the push-push assembly is positioned at an intermediate or home position between the discharged and the recharged position. In addition, the compression spring of the push-push assembly is in the compressed state when the door is unlocked. Further, an operator may provide a push to the handle to activate the handle. In other words, the operator may press the handle to activate it. 
     When the handle is pressed, the pusher first translates in a direction towards the frame of the door handle assembly, and then after reaching the first extreme position or the recharged position, the pusher translates in a direction away from the frame of the door handle assembly to the second extreme position or the discharged position. In other words, when the pusher translates to the first extreme position from the home position, the compression spring of the push-push assembly is further compressed which, when released, causes the pusher to translate from the first extreme position to the second extreme position decompressing the compression spring in the process. At the second extreme position, the pusher rests at the surface of the bell crank. In addition, the pusher is positioned at one end of the primary profile formed on the bell crank. 
     In order to unlatch the door, the operator needs to further actuate the handle to move the handle from the flush or undeployed position to the unlatched position. When the handle is moved from the flush position to the unlatched position, the handle forces the bell crank to rotate. When the bell crank rotates, the pusher undergoes relative motion with respect to the primary profile of the bell crank and moves from one end of the primary profile to another end. As a result of the relative motion between the pusher and profile, the pusher translates from the second extreme position to the first extreme position since the primary profile has a slanted shape. Accordingly, when the pusher moves from the second extreme position to the first extreme position, the compression spring moves to compressed state from decompressed state and the push-push assembly moves from the discharged condition to the charged condition. 
     Further, when the door is unlatched, the handle is released such that the handle does not exert any force on the bell crank. In absence of any external force, the bell crank rotates in opposite direction, such that the pusher gets disengaged with the primary profile. When the pusher is disengaged with the primary profile, the pusher moves from the first extreme position to the home position. Accordingly, the handle moves back to the flush position. 
     Therefore, a separate actuator is not required to actuate or recharge the push-push assembly when the push-push assembly is in the discharged condition. Further, since the push-push assembly can control the flushness of the handle with respect to the frame of the door handle assembly, a separate actuator is not necessary. Further, the push-push assembly of the present subject matter has a simple design and requires significantly less space. Therefore, the door handle assembly can also be used in vehicle having space constraint. Further, the overall cost and weight of the door handle assembly is significantly low due to small size of the push-push assembly and lesser number of components required to operate the door handle assembly. 
     The present subject matter is further described with reference to the accompanying figures. Wherever possible, the same reference numerals are used in the figures and the following description to refer to the same or similar parts. It should be noted that the description and figures merely illustrate principles of the present subject matter. It is thus understood that various arrangements may be devised that, although not explicitly described or shown herein, encompass the principles of the present subject matter. Moreover, all statements herein reciting principles, aspects, and examples of the present subject matter, as well as specific examples thereof, are intended to encompass equivalents thereof. 
       FIGS.  1 A- 1 D  illustrates different perspective views of a door handle assembly  100  in accordance with examples of the present subject matter.  FIG.  1 A  illustrates a first perspective view of the door handle assembly  100 , according to an example implementation of the present subject matter.  FIG.  1 B  illustrates a second perspective view of the door handle assembly  100 , according to an example implementation of the present subject matter.  FIG.  1 C  illustrates a third perspective view of the door handle assembly  100 , according to an example implementation of the present subject matter.  FIG.  1 D  illustrates a fourth perspective view of the door handle assembly  100 , according to an example implementation of the present subject matter.  FIG.  2    illustrates a magnified view of a portion of the door handle assembly  100 , according to example implementations of the present subject matter. For the sake of brevity and ease of understanding,  FIGS.  1 A- 1 D  and  FIG.  2    have been explained in conjunction with each other. 
     The door handle assembly  100  includes a frame  102  to be mounted to a door (not shown), such as of a vehicle. In an example, the frame  102  includes a housing portion (not shown) and an exterior surface having a cavity (not shown). The door handle assembly  100  includes a handle  104  disposed in the cavity of the frame  102 . The handle  104  has a gripping portion  106  and a handle base  108 . An operator of the door handle assembly  100  can grab the gripping portion  106  to move the handle  104  to lock/unlock or latch/unlatch the door. The handle  104  may be pivoted to the frame  102  by means of a pivot pin  110 . Further, the pivot pin  110  is coupled with a damper pin  112 . The damper pin  112  is adapted to restrict sudden movement of the pivot pin  110 , and thus provides adequate tactile experience to the operator while operating the handle  104  of the door handle assembly  100 . 
     In an example, the handle  104  is shaped to fit in the cavity of the frame  102  such that the handle  104  is flush with the exterior surface of the frame  102 . Further, the handle  104  may be movable between a flush or an undeployed position to a deployed position with respect to the frame  102 . For example, in the undeployed position, the handle  104  may be flush with the exterior surface of the frame  102  and in the deployed position, the handle  104  may protrude away from the cavity. Further, the door handle assembly  100  includes a first elastic member  114  by which the handle  104  is mounted to the frame  102 . The first elastic member  114  is adapted to bias against the handle  104  such that the handle  104  can return back to the flush position from the deployed position when no external force is applied by the operator. In an example, the first elastic member  114  may be a torsional spring. 
     To move the handle  104  from the flush or undeployed position to the deployed position, the handle  104  is given a first actuation. For example, when the operator pushes or presses the gripping portion  106  of the handle  104 , the handle  104  moves from the flush position to the deployed position. This may cause a portion of the handle  104  to protrude away from the cavity of the exterior surface of the frame  102  and the handle  104  may be considered in the deployed position. The operator may then pull the protruded portion of the handle  104  further away from the cavity to unlatch the door. The pulling action of the operator thereby results in opening the door. The action of pulling the protruded portion of the handle  104  further away from the cavity constitutes a second actuation and also unlatches the door. In response to the second actuation, the handle  104  is moved back to the flush position. In an example, the second actuation is provided in a direction opposite to the first actuation. 
     It is to be noted that although the foregoing description is provided with respect to a door, such as a vehicle door, the door handle assembly of the present subject matter may not be construed as limited to doors and may be implemented in vehicle interiors, liftgates or trunks of vehicles as well as in non-vehicle applications. 
     Further, the door handle assembly  100  includes a push-push assembly  116  operably coupled to the handle  104 . In an example, the push-push assembly  116  is operably coupled to the gripping portion  106  of the handle  104 . For instance, the push-push assembly  116  is in direct contact or directly coupled with the gripping portion  106  of the handle  104 . The push-push assembly  116  may be fixedly attached to the frame  102  of the door handle assembly  100  using fasteners, such as a screw. The push-push assembly  116  includes a body  118 , a control ring (not shown) and a compression spring (not shown) housed inside the body  118 , and a pusher  120  operably coupled to the compression spring. 
     The pusher  120  is adapted to translate along a longitudinal axis of the body  118  of the push-push assembly  116 . The control ring is adapted to regulate the movement of the pusher  120  in the body  118 . In said example, the pusher  120  can include a primary profiled pathway cut-out on its external lateral surface and the control ring can have a follower which can cooperate with the primary profiled pathway on the pusher  120 . Such a construction of the pusher  120  and the control ring for controlled movement of the pusher in various positions, such as holding the pusher  120  in the home position, the discharged position, and the recharged position (all explained in detail later) is based on the known constructions in the art. Further, the compression spring is adapted to provide bias to the pusher  120 . According to the present subject matter, the push-push assembly  116  is positioned substantially orthogonal to the handle  104 , when the handle  104  is in the flush or undeployed position. Due to the orthogonal positioning of the push-push assembly  116  with respect to the handle  104 , flushness of the handle  104  with respect to the frame  102  of the door handle assembly  100  can be controlled by the push-push assembly  116 . 
     Further, the actuation of the push-push assembly  116  governs the movement of the handle  104 . For instance, when the push-push assembly  116  is in a recharged condition, the handle  104  is in the flush or undeployed position. In the recharged condition of the push-push assembly  116 , the compression spring is in a compressed state, i.e., elastic potential energy is stored in the compression spring. Further, when the push-push assembly  116  is in a discharged condition, the handle  104  is in the deployed position. In the discharged condition of the push-push assembly  116 , the compression spring is in a decompressed state, i.e., elastic potential energy is released from the compression spring. 
     The door handle assembly  100  further includes a bell crank  122  that is pivotably mounted to the frame  102  and is operably coupled to the handle  104  and is also in cooperative engagement with the push-push assembly  116 . In an example, the handle base  108  is operably coupled to the bell crank  122 . The bell crank  122  includes a primary profile  124  (shown in  FIGS.  3 - 5   ) having a shape that assists in recharging the push-push assembly  116  from the discharged condition to the recharged condition. The pusher  120  of the push-push assembly  116  engages with the primary profile  124  formed on the bell crank  122  to recharge the push-push assembly  116 . In an example, as shown in the figures, the pusher  120  may have an arm  121  which cooperated with the primary profile  124  and causes movement of the pusher  120  inside the body  118 . However, the pusher  120  may cooperate with the primary profile  124  in other manners also such that the movement of the primary profile respective to the pusher  120  can cause translational motion of the pusher  120  similar to a relative motion between to a cam and its follower. 
     The primary profile  124  formed on the bell crank  122  may have a slanted shape. Further, the primary profile  124  is designed such that maximum height of the primary profile  124  is equal to the distance between a first extreme position of the pusher  120  and a second extreme position of the pusher  120 . The bell crank  122  further includes a second elastic member  126  by which the bell crank  122  is pivotably mounted to the frame  102 . The second elastic member  126  is adapted to move the bell crank  122  to its original or home position (i.e., position of the bell crank  122  when the handle is in the flush position) when the handle  104  is not actuated by the operator or when there is no external force applied on the handle. In an example, the second elastic member  126  may be a torsional spring. Further, the bell crank  122  includes a bell crank damper  128  adapted to restrict sudden movement of the bell crank  122 . Thus, the bell crank damper  128  ensures a smooth operation of the bell crank  122 . 
       FIGS.  1 A- 1 D  and  FIG.  2    illustrate different perspective views of the door handle assembly  100  when the handle  104  is in the flush or undeployed position. Initially, the door may be in a locked condition and can be unlocked using any of the known methods, for example, using a remote keyless system or a mechanical key. When the door is unlocked, the handle  104  is in the flush position and the pusher  120  of the push-push assembly is positioned at a home position which falls between the two extreme positions of the pusher  120 , i.e., the discharged position and the recharged position. In addition, the compression spring of the push-push assembly is in the compressed state when the handle  104  is in the flush or undeployed position. Further, the handle base  108  does not engage with the bell crank  122  when the handle  104  is in the flush or undeployed position. The operation of door handle assembly  100  when the handle  104  is moved from the flush position to the deployed position and vice-versa is explained in the following paragraphs. 
       FIG.  3    is a detailed illustration of working of the door handle assembly  100  when the handle  104  is moved from the flush position to the deployed position, according to an example implementation of the present subject matter. After the door is unlocked, the operator may provide a push to the handle  104  to activate the handle  104 . In other words, the operator may press the handle  104  to activate it. When the handle  104  is pressed, the compression spring is further compressed. Further, the compression spring biases against the pusher  120  to move the pusher  120  inside the body  118 . When the handle  104  is pressed, the pusher  120  first translates in a direction towards the frame  102  of the door handle assembly  100  to reach the first extreme position from the home position. Then, after reaching the first extreme position, the pusher  120  translates in a direction away from the frame  102  of the door handle assembly  100  to the second extreme position. When the pusher  120  reaches the first extreme position, the compression spring of the push-push assembly  116  starts decompressing. Further, when the pusher  120  translates from the first extreme position to the second extreme position, the compression spring decompresses and moves to the decompressed state. At the second extreme position, the pusher  120  rests at the surface of the bell crank  122 . The pusher  120  is positioned at one end of the primary profile  124  formed on the bell crank  122 . 
     The operator further actuates the handle  104  to move the handle  104  from the flush or undeployed position to the deployed position in order to unlatch the door. When the handle  104  is moved from the flush position to the deployed position, the handle base  108  rotates to make contact with the bell crank  122 . Further, upon further actuation, the handle base  108  forces the bell crank  122  to rotate. When the bell crank  122  rotates, the pusher  120  undergoes relative motion with respect to the primary profile  124  of the bell crank  122 . Due to the relative motion between the primary profile  124  and the pusher  120 , the pusher  120  moves from one end of the primary profile  124  to another end. Due to relative movement of the pusher  120  between the two ends of the primary profile  124 , the pusher  120  gains a height equal to the height of the primary profile  124 . Since, the primary profile has a height equal to the distance between the first extreme position and the second extreme position of the pusher  120 , the pusher  120  translates from the second extreme position to the first extreme position. The slanted shape of the primary profile  124  assists in relative motion between the pusher  120  and the primary profile  124  such that the pusher gains a height equal to the height of the primary profile  124 . When the pusher  120  moves from the second extreme position to the first extreme position, the compression spring moves to compressed state from decompressed state and the push-push assembly  116  moves from the discharged condition to the charged condition. 
       FIG.  4    is a detailed illustration of working of the door handle assembly  100  when the handle  104  is moved from the deployed position to the flush position, according to an example implementation of the present subject matter. When the door is unlatched, the handle  104  is released by the operator to move back to the flush or undeployed position. When the handle is released by the operator, the first elastic member  114  forces the handle base  108  to disengage with the bell crank  122 . Therefore, the handle base  108  does not exert any force on the bell crank  122  when the handle  104  is released by the operator. In absence of any external force, the second elastic member  126  forces the bell crank  122  to rotate in opposite direction. When the bell crank  122  rotates in the opposite direction, the pusher  120  gets disengaged with the primary profile  124 . When the pusher  120  is disengaged with the primary profile  124 , the pusher  120  moves from the first extreme position to the home position. Accordingly, the handle  104  moves back to the flush position. 
     Therefore, according to the present subject matter, a separate actuator is not required to actuate or recharge the push-push assembly  116  when the push-push assembly  116  is in the discharged condition. Further, since the push-push assembly  116  can control the flushness of the handle  104  with respect to the frame  102  of the door handle assembly  100 , a separate actuator is not necessary for controlling the flushness of the handle  104 . Further, the push-push assembly  116  of the present subject matter has a simple design and requires significantly less space. Therefore, the door handle assembly  100  can also be used in a vehicle having space constraint. Further, the overall cost and weight of the door handle assembly  100  is significantly low due to small size of the push-push assembly and lesser number of components required to operate the door handle assembly  100 . 
     In another implementation, the pusher  120  may have a plurality of arms, for example, two arms. In said implementation, the bell crank  122  may include a secondary profile  130  formed at its surface. The secondary profile  130  is formed away from the periphery of the bell crank  122 , such that the pusher  120  is positioned between the primary profile  124  and the secondary profile  130 . One of the arms, i.e., a first arm  121 , of the pusher  120  of the push-push assembly engages with the primary profile  124  as explained in above paragraphs. Further, the second arm  131  of the pusher  120  extends towards the secondary profile  130  formed on the bell crank  122 . Accordingly, the second arm  131  of the pusher  120  may engage with the secondary profile  130  similar to the engagement of the pusher  120  with the primary profile  124 . Therefore, the secondary profile  130  also assists in recharging the push-push assembly  116  when the push-push assembly is in the discharged condition. In a situation, where one of the arms of the pusher  120  breaks down due to continuous operation, the push-push assembly need not be replaced since another arm of the pusher  120  can engage with one of the primary profile  124  or the secondary profile  130  to recharge the push-push assembly. Accordingly, the serviceability of the door handle assembly  100  is improved. 
     In an example, the secondary profile  130  has a different shape from that of the primary profile  124 . For instance, the height of the secondary profile  130  may be similar to the height of the primary profile  124  but the slopes or the slants of the two may be designed differently with due regard to the difference in the distance of the two profiles from a pivoting centre of the bell crank  122 . In other words, the shapes of the primary profile  124  and the secondary profile  130  can be differently slanted such that when the pusher  120  moves along the two, the motion of the two arms  121  and  131  of the pusher  120  along the two profiles  124  and  130  is synchronized. 
       FIG.  5    illustrates different positions of the pusher  120  during operation of the door handle assembly  100 , according to example implementations of the present subject matter. For instance, when the handle  104  is in the flush or undeployed position, the pusher  120  is at the home position which is illustrated by reference numeral  132 . In other words, the reference numeral  132  illustrates that the pusher  120  is at the home position. Further, when the handle  104  is activated upon being pressed by the operator, the compression spring gets decompressed and the pusher  120  moves to the first extreme position which is illustrated by reference numeral  134 . In other words, the reference numeral  134  illustrates that the pusher  120  is at the first extreme position. Moreover, when the operator further actuates the handle  104  by pulling action provided by the operator, the pusher  120  moves from the first extreme position to the second extreme position which is illustrated by reference numeral  136 . In other words, the reference numeral  136  illustrates that the pusher  120  is at the second extreme position. Further, when the push-push assembly  116  is recharged due to engagement between the primary profile  124  and the pusher  120 , the pusher  120  moves from the second extreme position to the first extreme position. Finally, when the operator releases the handle  104 , the pusher  120  gets disengaged from the primary profile  124  and the pusher  120  moves from the first extreme position to the home position. 
     Although implementations of the door handle assembly  100  are described herein, it is to be understood that the present subject matter is not necessarily limited to the specific features of the systems or methods or other aspects described herein. Rather, these features are disclosed as implementations of the door handle assembly  100 .
