DETAILED DESCRIPTION

(14) FIG. 2 depicts an embodiment of a latch assembly 200 according to the present disclosure. As shown, the latch assembly 200 includes a latch housing 210 holding a latch mechanism 220 (see FIG. 4) and an integrated bumper 230 defined by a body 235 of resilient material defining a central opening 245 (see FIGS. 2, 4 and 5A-5E). In the depicted embodiment, the latch mechanism 220 is a push-push latch mechanism as is known in the art, although other latch mechanism designs are contemplated. With reference to FIG. 3, the latch housing 210 includes a base 240 which as will be described in greater detail is adapted whereby in the assembled device the bumper body 235 is concentrically disposed about a latch opening 250 defined by the base 240.

(15) As shown in FIG. 4, the bumper 230 is disposed on the base 240 to concentrically surround the latch opening 250. As will be described below, this allows the bumper 230 to provide a constant load around the latch opening 250 perimeter, i.e. in a 360 degree circumference around the latch opening 250 and therefore in a 360 degree circumference around a latch interface defined between a closure assembly (not shown) and a cooperating storage bin assembly (not shown). As will also be appreciated, the latch housing 210 may be molded by any suitable molding technique in a first shot and the bumper 230 may be molded in a second shot, or alternatively the latch housing may be molded in a first shot and placed in an appropriate secondary tooling for insert molding of the bumper.

(16) The bumper 230 includes a number of useful features. With reference to FIGS. 5A-5E and representatively referencing FIG. 5A, the bumper 230 is defined by the body 235 configured to concentrically surround a latch opening 250 defined by the base 240 as described above, and further includes at least one retainer 260 configured to provide a secure connection to a flange 270 of the base by way of cooperating apertures 300 (see FIGS. 3 and 6). The retainer 260 is defined by a post 280 extending from the body 235 and terminating in a head 290 which may comprise a variety of configurations including without intending any limitation a round head 290a (FIGS. 5A-5C), a larger round or mushroom head 290b (FIG. 5D), and a flat head 290c (FIG. 5E). The flat head 290c is contemplated for use in an alternative embodiment of a latch assembly 200 comprising a base flange 270 having cooperating apertures 300, as shown in FIG. 6 being configured to provide a recessed connection between the bumper 230 and the flange 270. As will be appreciated, these features allow tuning a clamp load applied to the bumper 230 by altering the amount of the load and the load distribution, all without requiring any change in material.

(17) In turn, the bumper body 235 includes a load edge 310 which likewise may comprise a number of configurations. In embodiments, the load edge may be defined as a planar load edge 310a (FIGS. 5A and 5D-5E), as a serrated load edge 310b (FIG. 5B), and as a scalloped load edge 310c (FIG. 5C). As will be appreciated, each of these load edge 310 configurations, by altering the number of contacts/spacing of contacts between the load edge and a latch interface (not shown), will provide a different load at the latch interface to customize the feel of opening and closing a storage bin closure provided with the latch assembly 200 as described herein.

(18) With reference to FIG. 7, the latch assembly 200 described herein is shown associated with a storage bin assembly 320. In the depicted embodiment, the storage bin assembly 320 is configured as a glove compartment disposed in a vehicle dashboard 330. The storage bin assembly 320 comprises a housing 340 (partially obscured by the dashboard 330 in this view) holding a pivoting closure panel 350 which is in turn configured to support or even define a storage bin 360. The closure panel 350 carries a latch assembly 200 as described above whereby the bumper 230 is oriented to contact a latch interface surface (not visible in this view) when the closure panel is pivoted to a closed orientation (see arrows).

(19) As will be appreciated, by use of the described latch assembly 200 numerous benefits accrue. By avoiding the need for multiple bumpers, complexity and cost of fabrication are reduced. In turn, by use of a single integrated bumper 230 as described, excessive tolerance stack as is encountered with multiple bumpers is prevented, improving fit and finish. Still more, by inclusion of the integrated bumper 230 as described, the latch mechanism 220 and associated internal components are protected during installation in a storage bin assembly 320. Still yet more, by inclusion of the integrated bumper 230 craftsmanship and quality are improved due to reduced componentry. By reducing componentry, concomitantly design concessions are reduced which would otherwise be required to accommodate additional components.

(20) The foregoing has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the embodiments to the precise form disclosed. Obvious modifications and variations are possible in light of the above teachings. For example, the latch assembly 200 has in the present document been described in the environment of a storage bin assembly 320 including a storage bin 360 configured as a glove compartment or other storage bin pivoting outwardly and downwardly from a dashboard 330. However, as will be appreciated, the described latch assembly 200 is equally adaptable to any vehicle storage bin assembly 320, including without intending any limitation an overhead bin associated with a vehicle roof panel or headliner, a door-mounted bin, a console-mounted bin, and others. Further, while a pivoting closure panel 350 defining a storage bin 360 is depicted herein, the latch assembly 200 is equally adaptable to a fixed storage bin having a pivoting closure panel associated therewith, to a sliding storage bin which slides between an open and a closed configuration along a vehicle y- or z-axis, and others.

(21) Further, as depicted herein the latch assembly 200 comprises a push-push latch mechanism 220. However, it will be appreciated that the described latch assembly and associated features and benefits are equally adaptable to other center-mounted latch mechanisms, to offset latch mechanisms, and others. All such modifications and variations are within the scope of the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
