The present invention relates generally to an attachment tab, and more specifically, to an interlocking key attachment tab designed to provide a structurally sound and secure lanyard attachment point for electronics covers and cases made from flexible elastomeric material, plastic or similar structural material.
In today's electronically connected world, cell phones and moreover smart-phones are largely ubiquitous and, the users of these devices, are constantly looking for aftermarket covers to protect their investment, distinguish their device from others, and to express their own personality through customization. There are a number of aftermarket covers, made from various material including, fabric, leather, metal, plastic and elastomeric materials, such as, vinyl, silicone or rubber. Each of the materials has different aesthetic appeal and provides varying degrees of protection for the device. However, the type of protective case used, will largely be determined by costumer preference.
Some users may prefer the additional security of attaching a leash or lanyard to the protective case. The leash or lanyard may be a wrist strap to protect the device from falls or the user may prefer to carry a device on a neck lanyard versus in a purse or pocket.
A lanyard attachment point can be formed into most protective cases, however, it is desirable to create a lanyard attachment point that does not substantially extend beyond the protective case envelope, does not create a pressure point or source of discomfort for the user and is a secure feature of the protective case. When a lanyard attachment point is formed into an elastomeric protective case, additional material thickness must be added to prevent the lanyard attachment point from tearing out of the soft and pliable material.
What is needed is a lanyard attachment point that can be formed into an electronic protective case that does not extend beyond the protective case envelope, does not create any user discomfort, and is a secure attachment point, even for protective cases made using an elastomeric material.
A first embodiment of the present invention is an interlocking key attachment tab with a corresponding socket formed into a planner base material. The attachment tab formed as a planner object or showing a thin vertical profile, having a body portion and a protruding tab portion. The body portion having, a first size and shape and the protruding ztab having a second size and shape, smaller than the size of the body portion. The protruding tab including, a neck portion and an attachment end; the neck portion and the attachment end, narrower than the body portion. In one embodiment, the tab portion is less than 10 percent narrower than the body portion, in another embodiment, the tab portion is 10 percent narrower than the body portion, in another embodiment, the tab portion is 20 percent narrower than the body portion, in another embodiment, the tab portion is 30 percent narrower than the body portion, in another embodiment, the tab portion is 40 percent narrower than the body portion, in another embodiment, the tab portion is 50 percent narrower than the body portion, in yet another embodiment, the tab portion is greater than 50 percent narrower than the body portion. The attachment end having an attachment hole formed through the planner material.
The corresponding socket formed into a first side of the planner base material, the socket depth equal to or greater than the thickness of the attachment tab. The socket formed having, a size and shape configured to correspond with the body portion of the attachment tab. The socket including a slot opening formed into a vertical surface, allowing the tab portion to be extended through to a second side of the base material.
The body portion of the attachment is installed into the socket on the first side of the planner material, with the tab portion placed through the socket opening, allowing the tab potion, with the attachment hole, to be exposed on the second side of the planner material. This configuration creates an attachment tab that extends to a second side of a planner material, that is secure and having a thin profile. When a load is applied the to the attachment tab, this configuration directs the load parallel to the surface of the planner material, distributing the pressure across a large area, and reducing the potential for base material or attachment tab failure. Where the planner material is an elastomeric material, such as, vinyl, rubber or silicone; the relatively soft and pliable material has a propensity to tear when an attachment tab is formed directly into the material. Whereas, when a durable material attachment tab is interlocked into the elastomeric material, the potential for failure due to tearing is greatly reduced.
One embodiment of the present invention is an interlocking key attachment tab with a corresponding socket including one or more shear lugs formed into the planner base material. The interlocking key attachment tab, having a body potion and attachment tab portion, the body portion having one or more cut-away areas or holes, the cut-away areas or holes having a distinct shape, a corresponding socket formed into a first side of a planner base material, a slot is formed in the vertical wall of the socket, and one or more shear lugs having the distinct shape of the cut-away areas or holes formed on the bottom surface. When the interlocking key attachment tab is inserted into the corresponding socket, the attachment tab portion is extended through the slot formed in the vertical wall of the socket; the attachment tab extending to the second side of the planner base material, the body portion is pressed into the corresponding socket with shear lugs engaged into the cut-away areas or holes in the attachment tab body portion. The shear lugs providing additional shear force distribution when the attachment tab is under load.
In one embodiment of the present invention, the body portion of the interlocking key attachment tab is configured as a unique or customizable shape. The shape of the body portion can vary, as long as, the width of the body portion is larger than the width of the neck portion of the attachment tab and the corresponding slot in the vertical wall of the socket. It is contemplated that the shape of the body portion can be, but is not limited to, an oval, circle, square, rectangle, diamond, triangle, pentagon, hexagon, octagon, heart, spade, clover, or other customizable shape as envisioned or requested by a second party or customer. It is contemplated that the body portion can be printed with a distinct pattern or can be embossed or include a pattern.
In yet another embodiment of the present invention, the interlocking key attachment tab includes a body portion and an attachment portion. The body portion formed from a first planner material and the attachment portion formed from a second cable or cordage type material. The attachment portion can be joined with the body portion by overmolding, adhesive or by mechanical means. It contemplated that the attachment portion can be formed using, but limited to, a loop of, stainless steel cable, nylon monofilament, nylon cordage and woven fiber such as Kevlar®. Additionally, it is contemplated that the attachment portion is configured as a releasable buckle, clip or a break-away assembly as commonly known in the art.
The above embodiments disclose using an interlocking key attachment tab in conjunction with a corresponding socket formed into planner base material. It contemplated that the planner base material, may be, but is not limited to, a plastic, nylon, vinyl, silicone, a metal, such as, aluminum, titanium, stainless steel or a composite such as fiberglass, graphite or Kevlar®.
