Elastic Bundle Tie

Abstract

An elastic bundle tie having an elongated strap and a tail that is inserted into a locking head. The self-locking head is located at the opposite end of the elongated strap from the tapered tail. The strap is a composite of a segmented ridged material and an elastic material. The tail is inserted through the head and the elongated strap is accepted within the head. The self-locking mechanism within the head latches onto the engagement teeth on the strap to maintain a user set position. The bundle tie that is formed has distributed elastic properties across the bundle. The distribution of the elastic properties provides a dampening effect evenly across the bundle, for all articles bundled, to protect the articles from applied force. The frictional properties of the elastic material may also limit movement for all articles in contact of the elastic material within the bundle.

Claims

1. The device bundles objects in a secure hold while protecting that which is bundled through elastic properties.

1. A bundle tie including: an elongated strap, said elongated strap including a composite structure of at least a segmented ridged material and an elastic material, maintaining elastic and dampening capability across the length of said elongated strap; a tapered tail connected to said elongated strap; a tie head connected to said elongated strap on opposite end of said tapered tail, said tie head including an opening configured to accept pass through of said tapered tail and to engage said elongated strap.

DETAILED DESCRIPTION OF THE INVENTION

[0010] This specification details one embodiment capable of providing the desired advantages that the invention offers. The specific embodiment shown is used to portray the advantages of the invention. While this embodiment may be specifically referenced to describe the advantages of the invention, the characteristics can be seen in one or more embodiments. The detail is provided for a thorough understanding of the invention, however it is seen that the invention may be practiced with a variation of the specific details, while still maintaining the advantages of the invention.

[0011] Bundle ties, also commonly referred to as cable ties, zip ties, or self-locking ties, are used to bundle, hold, and attach articles together. The present invention consists of specific characteristics that are not seen in previous arts, which provides a functional advantage over these prior works.

[0012] Conventional bundle ties have high potential to damage the articles that are bundled. Bundle ties generally include a locking head, an elongated strap, and a tail. The elongated strap is the primary component of the assembly that engages the articles to be bundled and holds them in place. The elongated strap is composed of a hard non-elastic material as the primary material on previous iterations of conventional bundle ties. Variants of the bundle tie show the use of elastic material to line the inner side of the strap to help protect the bundled articles. However, this does not provide any elastic properties to the structure of the tie itself, and does not allow the strap to lengthen. Furthermore, other variants of the bundle tie show the use of localized elastic properties, to provide a dampening effect in a single location. The isolated dampening effect of these iterations do not provide the benefits stated herein to all of the articles bundled.

[0013] Bundle ties with a strap comprised of ridged material, and those that use a rigid material as the primary structure lined with elastic material, do not allow for any lengthening of the strap. This is potentially hazardous to the articles that are bundled and does not provide the most effective hold. Bundle ties of prior art rely only on surface friction to hold the bundled articles together. Since the strap does not have elastic properties, the strap can only be tightened as much as the user is able to apply the tension on the tie. This can cause uneven loads distributed on the bundle articles, as well as an unreliable hold. This can cause damage to the articles over time.

[0014] Furthermore, articles bundled with conventional bundle ties, and variants of prior arts, are locked into place by a rigid material that does not have elastic properties, and does not provide any give when force is applied. This poses a hazard under most conditions that bundle ties are applied. Bundle ties are widely used under dynamic conditions meaning that the articles that are bundled are subject to changing loads. These loads cause significant stress on the articles that are bound together by a rigid material, even if there is an elastic lining or localized damper. Articles bundled with bundle ties can become damaged or break when loads are applied, which can also be hazardous to the surrounding environment. Even insignificant movement under typical conditions over a period of time can cause chaffing and breaking of the articles. A common use of bundle ties is seen throughout modern building structures, in which the ties are used to bundle electrical conductors. Articles such as these impose a potential hazard to the surrounding environment if damaged.

[0015] Therefore, one intent of the disclosure is to provide a bundle tie that bundles articles without causing stress points and damage to the articles that are bundled. Additionally, a further intent of the disclosure is to provide a tie that has elastic, spring like properties to enable give under loads or moving conditions. This property is aimed to protect all of the articles that are bundled at the time of bundle and also over a period of time afterward under normal load conditions, as well as accidental load applications.

[0016] An elastomer based bundle tie provides advantages to overcome all of the prior issues discussed with bundle ties that have a rigid material strap, even those that are lined with elastic material or incorporate a localized damper. The elastomer based bundle tie provides the ability for the tie strap to lengthen throughout the length of the strap and gives spring like properties throughout the fastener made with the tie, while all prior art does not.

[0017] The bundle tie is composed of three main parts; the head (1), the composite elongated strap (2), and the tail (3). The composite elongated strap (2) of the tie is composed of a primary elastic base (5) and multiple secondary shell pieces (4). The primary elastic base (5) of the tie is made of an elastic material, which gives the tie elastic, lengthening, and dampening properties. The secondary shell pieces (4) of the tie are made from a stiffer, durable material, which engage with the head (1) of the tie to create a locking mechanism. The head (1) of the tie is made from the same material used in the secondary shell pieces (4) of the composite elongated strap (2). The inner head latch engages with the grooves in the secondary shell pieces (4) of the elongated strap (2) to lock the tie into place. The locking mechanism created through the engagement of the head (1) and elongated strap (2) is seen in existing art. The tail (3) of the tie is on the other end of the elongated strap (2) from the head (1). This part of the tie is used to thread the elongated strap (2) into the head (1) of the tie. The tie can be created through double shot injection molding. First the primary elastic base (5) is formed through a first injection shot using an elastic material. Then the head (1), shell pieces (4), and tail (3) and fused to the elastic elongated strap (5) through a second injection shot using a stiff, durable material. The top shell pieces (4) are divided into parts to allow the primary elastic base (5), and overall elongated strap (2), of the tie to stretch when force is applied laterally or tangentially.
