ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates generally to devices for securing elongate items, such as wires, cables, hoses, tubing, conduits etc. More particularly, the invention relates to clamp ties that secure such items in spaced, parallel relationship with each other or in spaced, non-parallel relationship with each other.
Various devices have been developed for securing elongate items such as wires, cables, hoses, tubing, conduits, etc. Among these devices are clamps that secure a pair of such items in spaced, parallel relationship with each other. Examples of such clamps are shown in U.S. Pat. Nos. 3,654,669 and 3,981,048.
Although effective in securing elongate items to each other, neither of the devices shown in these patents made provision for securing the items not only to themselves but to a supporting structure as well. Such need arises, for example, in the trucking, automotive or other industry wherein a pair of hoses, lines or cables are to be spaced from each other and can be mounted to a vehicle frame member. Furthermore, prior devices did not include structure for maintaining a definite, preselected spacing between the items that were secured to each other. Such devices were ineffective in maintaining a desired spacing sufficient to avoid chaffing, heat transfer electromagnetic field transfer or other adverse consequences of insufficient spacing. The devices simply secured the items together without regard for the resulting spacing.
SUMMARY OF THE INVENTION
The invention provides a dual spacing clamp tie having a locking head, a pair of straps extending in opposite directions from the locking head, a first pawl mechanism within the locking head for engaging and retaining one of the straps, and a second pawl mechanism within the locking head for engaging and retaining the other of the straps.
The invention also provides a dual spacing clamp tie including a locking head having a pair of arcuate surfaces for engaging items to be secured, a pair of straps extending in opposite directions from the locking head and adjacent the arcuate surfaces, a first pawl mechanism within the locking head for engaging and retaining one of the straps, and a second pawl mechanism within the locking head for engaging and retaining the other of the straps.
The invention also provides a dual spacing clamp tie for securing elongate items adjacent a mounting member in spaced substantially parallel relationship to each other. The dual spacing clamp tie includes a locking head having a pair of arcuate surfaces for engaging the items and further having an aperture for receiving therethrough the mounting member. The dual spacing clamp tie further includes a pair of straps extending in opposite directions from the locking head and insertable through the locking head to form a loop in conjunction with each of the arcuate surfaces. A first pawl mechanism is provided within the locking head for engaging and retaining one of the straps in looped relationship with the locking head and one of the arcuate surfaces. A second pawl mechanism is provided within the locking head for engaging and retaining the other of the straps in looped relationship with the locking head and the other of the arcuate surfaces. The aperture is shaped and dimensioned to frictionally engage the mounting member to thereby retain the dual spacing clamp tie adjacent the mounting member until, if desired, a more permanent fastener can be applied.

A second pawl mechanism is provided within the locking head for engaging and retaining the other of the straps in looped relationship with the locking head and the other of the arcuate surfaces. A third pawl mechanism is provided within the aperture for engaging and retaining the mounting element within the aperture.
The invention also provides a dual spacing clamp tie comprising a locking head having a pair of arcuate surfaces for engaging items to be secured and having an aperture for receiving a mounting element therethrough, a pair of straps extending in opposite directions from the locking head and adjacent the arcuate surfaces, a first pawl mechanism within the locking head for engaging and retaining one of the straps, a second pawl mechanism within the locking head for engaging and retaining the other of the straps, and structure within the aperture for facilitating insertion of the mounting element into the aperture from one end only and for engaging the mounting member to secure the locking head to the mounting element.
The invention also provides a dual spacing clamp tie for securing elongate items adjacent a mounting member in spaced substantially parallel relationship to each other, comprising a locking head having a pair of arcuate surfaces for engaging the items and further having an aperture for receiving therethrough the mounting member, a pair of straps extending in opposite directions from the locking head and insertable through the locking head to form a loop in conjunction with each of the arcuate surfaces, a first pawl mechanism within the locking head for engaging and retaining one of the straps in looped relationship with the locking head and one of the arcuate surfaces, a second pawl mechanism within the locking head for engaging and retaining the other of the straps in looped relationship with the locking head and the other of the arcuate surfaces, and a third pawl mechanism within the aperture for permitting movement of the mounting element in a bi-directional direction therethrough while resisting movement of the mounting element in the opposite direction and for engaging and retaining the mounting element within the aperture.
In one embodiment, the first and second pawl mechanisms are releasable.
In one embodiment, the aperture is smooth-walled and undersized so that the dual spacing clamp tie is held in position on the mounting element through a friction or interference fit.
In one embodiment, the third pawl mechanism includes triangularly shaped pawls carried at the ends of elongate hinges within the aperture.
In one embodiment, the dual spacing clamp tie comprises a single unitary structure.
In one embodiment, the dual spacing clamp tie is formed of injection molded plastic.
The present invention further provides structure within the mounting element aperture wherein the mounting element aperture includes various novel means for engaging the mounting element.
Still another embodiment of the invention provides a bifurcated locking head defining two rotationally relative members, wherein one of the members includes the aforementioned mounting head aperture having structure for engaging the mounting element. This structure provides spacing for non-parallel, crossing elongated items or bundles. Any angle of the crossing elongated items can be accommodated by adjusting the locking head members.
