## Title
Routing clip elements with a living hinge and interlocking closure

## Abstract

A modular system of routing clip subcomponents having compatible interlocking features allows for as-needed assembly of multiple clips and extensions, thereby eliminating the need for specialized standoff brackets and clipping devices when routing vehicle wires, hoses, tubes, cables, harnesses, and the like. Generally molded from high-impact and decay resistant polymers, the elements of the modular system are inexpensive to manufacture and simple to assemble by hand.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to vehicle hose, tube, and wiring clips or retainers, and more particularly, to a modular system of individual clip or retainer sub-components which can be assembled in multiple configurations in order to meet varying installation requirements. The sub-components are molded from plastic or similar material, and are formed in such a way that they snap easily and securely together, interchangeably. In this way, the need for vehicle manufacturers to manufacture and stock a large number of specialized clips, standoffs, and extensions is eliminated.
2. Description of the Related Art
Ground traveling vehicles possess a large number of wires, hoses, tubes, cables, electrical harnesses, lines, and the like, which must be carefully clipped and routed to avoid chafing, interference with vehicle componentry, or exposure to adverse environmental factors, such as high temperatures. In order to accomplish this, vehicle manufacturers utilize a tremendous variety of plastic and metal clips, zip-ties, retainers, brackets, standoffs, and fasteners. This is inefficient from a manufacturing standpoint, and results in greater costs to the vehicle manufacturer, both in the price of the individual components, as well as in overhead costs associated with inventory and distribution of service parts.
SUMMARY OF THE INVENTION
It is the object of the present invention to reduce or eliminate the number of routing clips and brackets used by vehicle manufacturers by providing a modular system of clip sub-components that can be assembled as needed in order to meet the majority of such routing and clipping requirements. In order to accomplish this, a series of interlocking molded polymer elements are used. Typically, the polymer selected will be high-impact and ultraviolet decay resistant. The elements may be divided into several types, including mounting elements, straight extension elements, angled elements, and clip elements. They are provided with a common set of interlocking features, such as a barbed protrusion or protrusions that fit into a recess or slot, or posts that fit into corresponding holes, or even a lateral T-section that slides into a corresponding lateral T-slot. In any given embodiment, the interlocking features are designed in such a way that the parts lock together when assembled, preferably with a positive audible or tactile feedback, such that the elements “snap-together”. Further, the interlocking features may be configured so that they are releasable by manual manipulation, or by use of a tool.
The mounting element may simply be a body with a hole, which hole is provided in several common sizes, in increments of half a millimeter in the smaller sizes, full millimeters in the larger sizes, or sixteenths of an inch. In this way, a common fastener may be used to attach the mounting element to the vehicle. The mounting element may be provided with an overmolded metal insert for strength in compression, so that the common fastener may be tightened securely. The hole, whether in the parent molded material of the mounting element, or whether in the overmolded metal insert, may be threaded with or without a locking feature, so that only a male common threaded fastener need be used to attach the mounting element to the vehicle. The threads provided may be in metric or SAE standard. Alternately, the mounting element may be provided with a mounting stud, whether formed out of the parent molded material, or as an overmolded or otherwise attached metal insert. The stud may be provided in several sizes and lengths, with metric or SAE standard thread. Further embodiments of mounting elements include elements provided with a fir-tree or rosebud press-in type feature insertable into a hole provided in the vehicle structure, and elements provided with a high-bonding adhesive backing.
The extension elements are provided in incremental lengths of about fifteen millimeters or half an inch increments. Angled elements in the same way are molded in incremental angles of about fifteen degrees increment, except that a single smaller angle element may be available, such that the elements available may be 7.5°, 15°, 30°, 45°, and so forth. Further, one or more twist elements, or elements that change angle along the long axis, may be provided. Elbows and tees may be part of the set of modular elements as well.
The line clipping or retainer elements are generally cylindrical with a separation along one side, and a living hinge along the other, generally opposed side. There are interlocking closures between the two hinged halves, such that once the clip is closed around a hose or tube, it locks in the closed position. Similar to the interlocking features used to assemble the elements, the interlocking closures between the two hinged halves may be configured so that they are releasable by manual manipulation, or using a tool. The interlocking closures used to hold the line clip or retainer closed may be co-planar with the interlocking features used to assemble the elements, or the interlocking features used to assemble the elements may be located perpendicular to the interlocking closures. Further, the axis of the line clip or retainer may be oblique to the axis of the body of the modular clip element. The axis of the line clip or retainer may even be rotatable relative to the body of the modular clip element.
Another embodiment of the line clipping or retainer element involves the use of a resilient clip as is well-known in the industry, wherein the clip is generally cylindrical with an opening along its axis that is of a lesser distance that the diameter of the hose or tube to be inserted into it. Again, the axis of the line clip or retainer may be oblique to the axis of the body of the modular clip element.
