The tail is then passed through the passageway of the holding tab in the second direction and the tail is bent around the holding tab so as to extend back in the first direction.

Description

FIELD OF THE INVENTION

The present invention relates generally to a tie for bundling one or more articles. More particularly the present invention relates to a stainless steel bundling tie which may be secured around the articles.

BACKGROUND OF THE INVENTION

The art has seen the use of bundling or cable ties for securing one or more articles. These ties may be formed of a wide variety of materials based on the particular application.

In certain industrial applications, due to a particular environment where a tie used, the tie must be formed of material capable of withstanding adverse conditions. Such conditions are found, for example, in marine and chemical plant environments.

The art has seen the use of stainless steel ties which allow a plurality of articles such as wires and cables to be bundled together. By virtue of the material forming the tie, the stainless steel tie is able to withstand these adverse environment. One example of a stainless steel cable tie useful in adverse environments is shown in U.S. Pat. No. 4,765,032 to Fortsch.

While these stainless steel ties serve adequately in withstanding the adverse environments encountered, many of the stainless steel ties require specialized tools to adequately secure the tie around the articles. Once secured with a tool, these ties are ordinarily not reusable. In situations where tools are not employed, the tie may not exhibit the requisite tensile strength necessary to maintain a secure engagement around the bundle.

It is, therefore, desirable to provide a bundling tie formed of stainless steel which can be securely maintained around a bundle of articles such as wires and cables without the need for using tools to effect such securement and which exhibits the requisite tensile strength.

SUMMARY OF THE INVENTION

The present invention provides a method for bundling an article or a plurality of articles using a tie. The method includes providing a deformable tie having an elongate strap including an elongate tail at one end and a locking head at the other end. The locking head includes a pair of holding tabs defining a passage therethrough and a slot spaced from the holding tabs having a raised wall. The tie is placed about the article to be bundled. The tail is inserted through the passage of the holding tabs in the first direction. The tail is then passed through the slot in the first direction. The tail is bent about the raised slot wall so as to extend in a second direction opposite the first direction. The tie is then passed through the passage of the holding tab in the second direction. The tie is then bent around the holding tab so as to extend back in the first direction.

In a preferred embodiment of the present invention, the tie is formed of a plastically deformable metal, more preferably stainless steel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to the figures, the present invention provides a cable tie 10 which may be secured around a bundle 50 of articles 52 (FIG. 6). As used here and throughout, the term “cable tie” refers to a bundling strap or tie, having a tail at one end and a locking head at the other end. The articles 50 may include one or more electrical cables or any other elongate elements that are bundled together where there is a desire to secure the bundle of articles.

Referring now to FIGS. 1 through 6, the tie employed in the method of the present invention is shown.

The tie 10 is an elongate member similar to those of conventional construction. Tie 10 includes an elongate strap body 12 having an elongate tail 14 at one end and a locking head 16 at the opposite end. In the present illustrative embodiment, the tie 10 is formed of a deformable material. Preferably, the tie is formed of a material which may be plastically deformed such that once deformed the material will maintain its deformed shape. More specifically, in the present embodiment, the tie is formed of stainless steel.

The present invention provides a novel method of securing the tail to the head without use of tools and which provides the requisite tensile strength necessary to retain the bundled articles.

The tie 10 may be wrapped around a plurality of articles 52 and then the tail 14 is inserted into the head 16 to provide secure locking engagement thereto. The tail 14 of the present invention has a tapered or rounded distal extent 14a which facilitates insertion thereof into the head as will be described in further detail hereinbelow.

Head 16 includes at a distal end thereof, a pair of inwardly facing tabs 18 which are raised from the plane of the head so as to define an insertion passageway 20. It is also contemplated that the tabs 18 may define a continuous joined tab defining passageway 20. Spaced from passageway 20, the head 16 also includes a wall 22 raised from the plane of the head which defines a slot 24 therethrough.

It is contemplated that the head 16 of cable tie 10 may be manufactured in a flat configuration and the tabs 18 as well as the slot wall 22 can be struck outwardly therefrom. Such manufacturing results in both the passageway 20 and the slot 24 being on the same plane so as to accommodate the insertion of the tail 14 therethrough.

With reference to FIGS. 1-5, the successive steps of securing a tie around the plurality of articles 52 may be described. Tie 10 is wrapped around articles 52 in conventional fashion. The tail 14 is then inserted through the passageway 20 so that it extends in a direction indicated by arrow A. The tail 14 is further advanced in the direction of arrow A so that the tail extends through slot 24. The tail is pulled in the direction of arrow A until sufficient tension is maintained around the bundle 50. Thereafter, as shown in FIG. 2, the tail is bent upwardly at a 90° angle to extend in a direction of arrow B. Slot wall 22 provides leverage for such bending while maintaining tension around the bundle 50. As the stainless steel material is plastically deformable, such bending will maintain tension of the tie 10 around the bundle 50. Thereafter, the tail 14 is bent downwardly so as to extend in the direction of arrow C which is opposite the direction of arrow A. In this regard, and referring to FIG. 3, the tail is inserted back through passageway 20 so that the tail 14 overlies strap body 12. In the position shown in FIG. 3, the tail is essentially folded back over itself. The space between the holding tabs, in the preferred embodiment, aids in reinsertion of the tail 14 into passageway 20.

Referring to FIG. 4, the tail 14 is bent upwardly to extend in the direction of arrow B. The tabs 18 provide leverage so as to maintain tension around the bundle. Thereafter, as shown in FIG. 5, the tail is again folded downwardly so that it extends in a direction of arrow A, the original insertion direction.

In making each of these bends, it is desirable to make the bends as sharp as possible so as to maintain adequate tension on the bundle.

The present invention thus contemplates double folding the tail about the head, forming two separate bends each at 180°. Such double folding maintains the tensile strength of the tie around the bundle without the need for a tool to permanently crimp the tail to the head. Moreover, as the securement of the tail to the head is by virtue of deforming the tie, the tie may be released by reversing the steps shown in FIGS. 1-5. This results in the tie being reuseable.

Turning now to FIGS. 7 and 8, an alterative arrangement for securing a cable tie around a bundle of articles is shown. Cable tie 110 is substantially similar to cable tie 10 described above. Cable tie 110 includes a head 116, a tail 114, and an elongate strap body 112 therebetween. The head 116 includes, at a distal end thereof, a pair of inwardly facing tabs 118 which are raised from the plane of the head so as to define insertion passageway 120. Spaced from passageway 120, the head 116 includes a wall 122 raised from the plane of the head which defines a slot 124 therethrough.

In addition, in the embodiments shown in FIGS. 7 and 8, locking head 16 includes a central aperture 125 located in intermediate passageway 120 in slot 124. As will be described in further detail hereinbelow, aperture 125 is used additionally for securement of the tail 114 in head 116.

Referring now specifically to FIG. 8, the tail 114 is inserted into head 116 in the following manner. The tail is inserted through central aperture 125 in the direction of arrow A. The tail 114 is then extended in the same direction through slot 124. The tail would then be bent around wall 122 and back onto itself in a manner similar to that described above so as to extend in a direction of arrow C which is opposite arrow A. The tail 114 is then advanced in the direction of arrow A so as to extend back through passageway 120 so that the tail lies over itself in the direction of arrow C. Thereafter, the tail can be bent upwardly using tabs 118 as leverage so that it extends at an angle 90° therefrom. Subsequently, the tail can be bent further so as to extend again in the direction of arrow A or the upwardly tail could be severed at tabs 118.

Various changes to the foregoing described and shown structures would now be evident to those skilled in the art. Accordingly, the particularly disclosed scope of the invention is set forth in the following claims.
