Adjustable-Height Support Member
An adjustable-height support member, also referred to as a chair, provides support in a panel assembly having an inner wall and an outer wall. The chair includes a base configured for attachment to an interior surface of the inner wall. A shaft extends from the base. An optional cap covers the shaft such that the total length of the chair corresponds with a desired thickness between the inner wall and the outer wall of the panel assembly. During assembly, the chair prevents sagging between the inner wall and the outer wall. The chair also allows the insulating foam to be applied so as to substantially fill the void between the inner and outer wall.
This application is a Divisional of U.S. application Ser. No. 12/860,488, filed on 20 Aug. 2010, titled “Adjustable-Height Support Member,” which claims the benefit of U.S. Provisional Application No. 61/279,299, filed 19 Oct. 2009, titled “Tri-Chair and cap,” all of which are hereby incorporated by reference for all purposes as if fully set forth herein.
BACKGROUND1. Field of the Invention
The system of the present application relates to a method and apparatus for supporting flexible panel members during assembly.
2. Description of Related Art
A typical walk-in refrigerator includes a series of insulated panels attached together to form an enclosure. A basic insulated panel typically includes an outer wall and an inner wall with insulating foam therebetween. During assembly of the insulated panel, the outer wall and the inner wall have a tendency to sag or otherwise distort before the insulating foam can be used to rigidly fill the void between outer and inner walls.
Although great strides have been made in the area of insulated panel assemblies, considerable shortcomings remain.
The novel features believed characteristic of the system are set forth in the description. However, the system itself, as well as, a preferred mode of use, and further objectives and advantages thereof, will best be understood by reference to the following detailed description when read in conjunction with the accompanying drawings, wherein:
While the system of the present application is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and are herein described in detail. It should be understood, however, that the description herein of specific embodiments is not intended to limit the system to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the system as described herein.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTIllustrative embodiments of the system of the present application are described below. In the interest of clarity, not all features of an actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developer's specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

The method of manufacturing a panel assembly 101 further includes adjusting the length of each chair 201, if necessary. As previously described, chair 201 is configured to be adjustable. Portions of shaft 203 may be removed to shorten chair 201 to correspond with an inner thickness of panel assembly 101. Such a feature of chair 201 allows it to be used in a variety of panel assemblies 101 of varying thicknesses, thereby preventing a manufacturer from having to stock multiple support members, each of unique length. Chair 201 is configured to be shortened by applying a bending force to snap off a portion of shaft 203 in order to shorten chair 201. Chair 501 is configured to be shortened by cutting, sawing, or the like, at the indentations. Chair 601 is configured with visible marks which provide a visual guide as a location for cutting, sawing, or the like. It should be appreciated that other alternative embodiments of chair 201 may not include any indicator; instead, such an embodiment may employ the use of an external tool for cutting each chair to a predetermined length, as set by a feature on the tool.
Referring still to
It is apparent that a system with significant advantages has been described and illustrated, including a convenient device and method for preventing the sagging of walls during assembly of a insulate panel.
The particular embodiments disclosed above are illustrative only, as the system may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teachings herein. The particular embodiments disclosed herein may be altered or modified, and all such variations are considered within the scope and spirit of the present application. Although the system of the present application is shown in a limited number of forms, it is not limited to just these forms, but is amenable to various changes and modifications without departing from the spirit thereof.
