Abstract
A parts rack for holding automotive parts for shipping and storing parts in the course of assembling of automobiles including a three dimensional framework which is assembled from elongated members detachably connected together using steel connectors to allow shipping of the racks disassembled and to allow quicker deliveries and also readily allow reconfiguration, repairs, and salvage of components.
Description
- This application claims the benefit of U.S. provisional patent application No. 60/883,611 filed on Jan. 5, 2007.
- This invention concerns racks and more particularly racks for holding parts required in the production of automotive vehicles. Such racks are typically used to for bulky body parts during shipping, and also in plant storage and to hold parts for the sequencing necessary in the assembly process.
- When a part holding rack is loaded it can be severely stressed during shipping by sudden stops, impacts, etc on trains and trucks, and must be sufficiently sturdy to avoid excessive deformation which would require repair of the rack.
- Such part holding racks have thus been typically constructed as a steel framework weldment, which is heavy and subject to corrosion. Also, steel being rigid, is susceptible to permanent deformation when severely loaded despite its great strength. Aluminum has also been used but its higher cost and lower strength has limited its used for this purpose.
- The major problem in such part holding racks is their cost and the time required to design and build the racks. This is because a great variety of part shapes are required to be accommodated, which part shapes changes from year to year.
- This has necessitated a custom design for most parts and a great number of holding rack configurations is required.
- A welded framework construction while providing strength has the disadvantage of being bulky when being shipped and making repairs on damaged racks difficult. Modification to accommodate different part shapes are difficult or completely impractical.
- It is an object of the present invention to provide a part holding rack for automotive assembly which can be shipped disassembled for compactness, and easily assembled on site.
- It is yet another object to provide a part holding rack which has components which can be removed and reused if other components are damaged, or if the rack becomes obsolete.
- It is still another object provide part holding racks which can be quickly designed and built in many different configurations and which can be easily modified to accommodate a different part.
- These and other objects of the present invention which will be understood upon a reading of following specification and claims are achieved by a modular construction of a three dimensional framework part holding rack according to the invention. This construction includes a framework provided by an array of horizontal and vertical elongated members assembled together with connector fittings receiving and holding member ends.
- A welded rectangular frame base has an assembled thereto an upper framework with corner posts receiving the lower ends of vertical members forming portions of the upper framework.
- The elongated members and connectors can be reused if the rack is damaged and also allow reconfiguration of the rack by relocating the connections and/or shortening of the elongated members.
- The part holding racks may be shipped flat and disassembled and put together on site with unskilled labor.
- Variously configured racks can be quickly designed and assembled from the modular components. The elongated members can be made of metal or advantageously of a lightweight low cost composite materials and can be easily cut to any desired length to produce a rack of any particular design.
