The present disclosure relates to a latch assembly and, more particularly, relates to a configurable latch assembly that can be configured in various ways for selectively latching a cover member to a base structure.
Glove boxes, cup holders, cargo areas, and other areas within a vehicle can include a base structure that defines a cavity and a cover member or door that can move between an open position and a closed position relative to the base structure. In the open position, the cover member can be positioned away from the base, thereby revealing the contents of the cavity. In the closed position, the cover member can be positioned adjacent the base structure, thereby covering the cavity. In some embodiments, the cover member can be pivotally coupled to the base structure, for instance, via a hinge or other hardware.
Moreover, a latch assembly can be included for selectively securing the cover member to the base in the closed position. The latch assembly can have a latched position, wherein the latch assembly secures the cover member to the base, and the latch assembly can also have an unlatched position, wherein the latch assembly releases the cover member from the base.
A modular latch assembly for selectively securing a cover member to a base due to actuation of an input member is disclosed. The input member includes an input engagement member. The latch assembly includes an arm that is supported for substantially linear movement between a latched position and an unlatched position. The arm secures the cover member to the base when in the latched position, and the arm releases the cover member from the base when in the unlatched position. The arm includes an arm engagement member. Moreover, the latch assembly includes a link that is operably coupled to the arm for rotation relative to the arm simultaneously as the arm moves between the latched and unlatched positions. The link includes a link engagement member. The arm and the link have a first modular configuration in which the arm engagement member is configured to engage the input engagement member due to selective actuation of the input member, thereby resulting in simultaneous movement of the arm between the latched and unlatched positions and rotation of the link. The arm and the link also have a second modular configuration in which the link engagement member is configured to engage the input engagement member due to selective actuation of the input member, thereby resulting in simultaneous movement of the arm between the latched and unlatched positions and rotation of the link.
Moreover, a modular latch assembly for selectively securing a cover member to a base due to actuation of an input member is disclosed. The input member includes an input engagement member. The latch assembly includes a first arm and a second arm that are supported for substantially linear movement in different directions between a latched position and an unlatched position. The first and second arms secure the cover member to the base when in the latched position, and the first and second arms release the cover member from the base when in the unlatched position. At least one of the first and second arms includes an arm engagement member. Moreover, the latch assembly includes a link that is operably coupled to the first and second arms for rotation relative to the first and second arms simultaneously as the first and second arms move between the latched and unlatched positions. The link includes a link engagement member. The first and second arms and the link have a first modular configuration in which the arm engagement member is configured to engage the input engagement member due to selective actuation of the input member, thereby resulting in simultaneous movement of the first and second arms between the latched and unlatched positions and rotation of the link. The first and second arms and the link also have a second modular configuration in which the link engagement member is configured to engage the input engagement member due to selective actuation of the input member, thereby resulting in simultaneous movement of the first and second arms between the latched and unlatched positions and rotation of the link.
Further areas of applicability of the teachings of the present disclosure will become apparent from the detailed description, claims and the drawings provided hereinafter, wherein like reference numerals refer to like features throughout the several views of the drawings. It should be understood that the detailed description, including disclosed embodiments and drawings referenced therein, are merely exemplary in nature intended for purposes of illustration only and are not intended to limit the scope of the present disclosure, its application or uses. Thus, variations that do not depart from the gist of the present disclosure are intended to be within the scope of the present disclosure.
Referring initially to
It will be appreciated that the latch assembly 10, cover member 12, and base 14 can define another type of container other than a glove box. For instance, these components can define a rear cargo box, a cup holder, etc., of a vehicle. Also, the latch assembly 10, cover member 12, and base 14 could be associated with a container that is not associated with a vehicle.
In some embodiments, the cover member 12 includes an outer panel 18 that defines a recess 19 (
The base 14 can also include at least one opening 22, which is defined in a respective block 24 as shown in
The latch assembly 10 can be mounted substantially between the inner and outer panels 18, 20 of the cover member 12 as will be discussed in detail below. Also, as will be discussed, the latch assembly 10 can have a latched position (
An input member 62 can also be included for selectively moving the latch assembly 10 between the latched and unlatched positions as will be discussed. The input member 62 can be of any suitable type, such as a lever, handle, button, slider, etc. Also, the input member 62 can be moveably mounted to the cover member 12. Thus, assuming that the cover member 12 is in the closed position over the base 14, and the latch assembly 10 is in the latched position (
As will be discussed in detail below, the latch assembly 10 can have several modular configurations. As such, the latch assembly 10 can accommodate various types of the input members 62. Also, the latch assembly 10 can be modularly configured to accommodate input members 62 that are mounted to the cover member 12 in a variety of ways. In each of these configurations, many parts of the latch assembly 10 can be the same in each modular configuration. Thus, the latch assembly 10 can be manufactured and assembled in a very efficient manner. For instance, tooling (e.g., molds) can be the same for each configuration, which can reduce manufacturing costs. Also, assembly of the latch assembly 10 in each configuration can be largely the same, resulting in greater efficiencies.
Referring now to
The latch assembly 10 can further include a link 36. In the embodiments of
The link 36 can also include a first opening 40 and a second opening 42. The openings 40, 42 can be notches, slots, grooves, or any other type. The openings 40, 42 can be spaced 180 degrees apart from one another about the hub 38, and the openings 40, 42 can be spaced radially from the hub 38 at substantially equal distances.
Moreover, the link 36 can include at least one link engagement member 43. In the embodiments illustrated, the link engagement member 43 is a recessed surface, hole, or other opening formed therein. The link engagement member 43 can be radially spaced from the hub 38 and can be circumferentially spaced from the second opening 42. It will be appreciated that the link engagement member 43 can also be a projection or other object in some embodiments. As will be discussed in detail below, the link 36 can rotate when the latch assembly 10 moves between the latched and unlatched positions. Also, as will be discussed, the link assembly 10 can be configured so that the link engagement member 43 engages with the input member 62. Accordingly, actuation of the input member 62 can drive rotation of the link 36 such that the latch assembly 10 moves between the latched and unlatched positions.
Additionally, the latch assembly 10 can include a biasing member 44. The biasing member 44 can be of any suitable type, such as a leaf-spring or other resilient member. As shown in
Furthermore, the latch assembly 10 can include at least one arm 46, 54 that is operably coupled to the link 36 for linear movement that occurs simultaneously and/or as a result of rotation of the link 36. Specifically, in the embodiments illustrated, there is a first arm 46 and a second arm 54. Each arm 46, 54 can be elongate. As such, the first arm 46 can include a first end 48 and a second end 52. The first end 48 can be adjacent the link 36 and can include a post 50 that is moveably received within the second opening 42 of the link 36. The second end 52 can extend out of the housing 26 and can terminate adjacent one of the openings 22 in the base 14. Similarly, the second arm 54 can include a first end 56 and a second end 60. The first end 56 can be adjacent the link 36 and can include a post 58 that is moveably received within the first opening 40 of the link 36. The second end 60 can extend out of the housing 26 (in a direction opposite that of the first arm 46), and the second end 60 can terminate adjacent the other opening 22 in the base 14. In the latched position, the second ends 52, 60 of the arms 46, 54 can be received within the openings 22 to secure the cover member 12 to the base 14. In the unlatched position, the second ends 52, 60 can be moved out of the openings 22 to release the cover member 12 from the base 14.
Accordingly, both the first and second arms 46, 54 can move linearly relative to the openings 22 in the base 14 to move between the latched and unlatched positions. In the embodiments illustrated, both the first and second arms 46, 54 can move substantially parallel to the X-axis, albeit in opposite linear directions. Also, as should be apparent, the arms 46, 54 can move linearly while the link 36 rotates about its axis. Moreover, linear movement of one of the arms 46, 54 can cause rotation of the link 36 as well as linear movement of the other arm 46, 54. On the other hand, rotation of the link 36 can cause linear movement of both arms 46, 54. Furthermore, the biasing member 44 can bias the link 36, thereby biasing the arms 46, 54 toward the latched position. The latch assembly 10 can additionally include bumpers or other objects or surfaces that limit linear movement of the arms 46, 54 (e.g., when the arms 46, 54 reach the unlatched position and/or when the arms 46, 54 reach the latched position).
In the embodiments illustrated in
As mentioned above, the latch assembly 10 can also include the input member 62 (
Operation of the latch assembly 10 will now be discussed. Assuming that the components are in the position shown in
Upon release of the handle portion 64, the input member 62 can be biased back toward the outer panel 18. Since the input engagement member 68 will be spaced away from the arm engagement member 53 (see
Like the embodiments of
Additionally, the input member 162 can include a projection 174 that extends toward the link 136 and that terminates to define the input engagement member 168. The input engagement member 168 can include a rounded surface.
Also, like the embodiments of
Thus, as the input member 162 rotates about the axis of the rod 170, the input engagement member 168 can slide on and cam against the link engagement member 143. As a result, the link 136 can rotate about the hub 138 (
Accordingly, even though the input member 62 of
As shown, the input member 262 can be a pushbutton that is moveably mounted for linear movement (e.g., substantially parallel to the Y-axis). The attachment portion 266 can slidingly extend through the housing 226 and can include a flange 273 that extends parallel to the Y-axis. The attachment portion 266 can also include a projection 274 (e.g., a post) that projects transversely (e.g., parallel to the Z axis). Also, the link engagement member 243 can be a slot that extends radially inward on the link 236. The projection 274 can be moveably received within the link engagement member 243.
Thus, when the user presses the button-type input member 262 against the biasing force of the biasing member 280 (as indicated by the arrow labeled âFâ in
The input member 362 can also include a projection 374 that terminates at the input engagement member 368. The input engagement member 368 can directly engage the arm engagement member 353. In the embodiments illustrated, the arm engagement member 353 is a hole, recess, or other opening that receives the input engagement member 368.
Thus, when the input member 362 is pulled against the biasing force of the biasing member 344 along the rod 370, the input engagement member 368 can push against the interior of the arm engagement member 353 to push the corresponding arm toward the unlatched position. It will be appreciated that the input member 362 and the arm can move substantially parallel to each other as indicated by two horizontal arrows in
Finally,
As shown, the input member 462 can be a pushbutton that moves linearly (e.g., parallel to the Z-axis). The input member engagement member 468 can project toward the arm 454 and terminate at a ramp surface 482. The ramp surface 482 can be disposed at an acute angle relative to the X-axis in the X-Z plane.
Furthermore, the arm engagement member 453 can include a complimentary ramp surface 484 that can slidingly engage the ramp surface 282 of the input engagement member 468. Thus, when the input member 462 is pushed inward along the Z-axis, the ramp surface 468 can travel and slide along the face of the ramp surface 484. As a result, the arm 454, link 436, and arm 446 can actuate as discussed above.
Accordingly, the modular latch assembly of the present disclosure can include basic parts, such as the link, the arms, the housing, the fasteners, bumpers, etc. can remain the same regardless of the configuration. Thus, the latch assembly can be manufactured and assembled efficiently.
The latch assembly can also be varied from the illustrated embodiments. For, instance, several examples are illustrated and described wherein a projection is received within an opening for engaging two separate parts. As a specific example, the projection 274 is received within the link engagement member 243 of
