Methods and apparatus for fastening panels

Abstract

An apparatus for coupling a panel to a frame includes: a support plate coupled to the panel; an engagement plate extending transversely from the support plate and having an aperture extending therethrough; and a clip having a pivotable arm extending from the support plate at a first end, and at least partially under the aperture to a second end, wherein the plate, aperture and clip are sized and shaped to slideably receive a head and shaft of a mating fastener, coupled to the frame, toward the support plate such that the second end of the pivotable arm engages the head when the shaft is fully received in the aperture.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to methods and apparatus for fastening panels together, such as for securing a door trim panel to a door module of a vehicle. [0002] Door trim panels are employed as interior components on automotive vehicles. One of the purposes of such interior trim panels is to present an aesthetically pleasing appearance. Door trim panels are typically mounted to structural support members on the door module. For example, door trim panels are mounted to an inner door sheet metal panel or to a door module (or frame) which replaces the traditional inner door sheet metal of the automotive vehicle. [0003] There exist a variety of conventional fasteners for attaching panels to support members in the automotive industry. A common problem with assembling such panels has been that the fasteners are difficult to align with mating fasteners in the sheet metal of the frame. As a result, misaligned fasteners sometimes result in a mallet being ...

Benefits of technology

[0012] Among the advantages of the embodiments of the invention includes the ability to reduce the depth dimension of the doghouse as compared with some conventional designs without sacrificing retention of the pin in the doghouse. In particular, the doghouse depth may be reduced at least in part because the clip extends from the first end at a rear of the aperture to the second end terminating toward (and / or forward) of the aperture. Thus, additional structural footprint need not be employed to accommodate a clip extending from the opposite direction.

[0017] The apparatus may further include at least one guide rib having at least a portion of a surface sloping toward the engagement plate to guide the head and shaft of the mating fastener into the aperture. For example, the at least one guide rib may include a respective guide rib disposed on opposite sides of the aperture, each guide rib having at least a portion of a surface sloping toward the engagement plate to guide the head and shaft of the mating fastener into the aperture. The guide rib(s) prevent the head from moving downward through the aperture and placing excessive pressure the clip (which might damage the clip and other structures).

[0018] In accordance with one or more aspects of the present invention, a method for coupling a panel to a frame includes: coupling an engagement plate substantially parallel to the panel, the engagement plate having an aperture extending therethrough which is oriented transversely to the panel, and a slot extending from a leading edge of the engagement plate to the aperture, the slot including inwardly directed side surfaces operable to guide a head and shaft of a mating fastener into the aperture; providing a clip having a pivotable arm extending from a first end at least partially under the aperture and at least toward the leading edge of the engagement plate to a second end; slideably receiving the head and shaft of the mating fastener into the aperture; and preventing the head and shaft of the mating fastener from sliding out of the aperture through the slot using the clip in tension.

Problems solved by technology

Thus, additional structural footprint need not be employed to accommodate a clip extending from the opposite direction.
