The present invention relates generally to a pad for use under a covering layer, and in particular, to a pad that has an off-all portion with a puzzle-piece shape.
The use of pads or mats under a covering layer is known. For example, a covering layer, such as a carpet, typically has a pad or mat between itself and the floor in order to provide a cushioned layer therebetween. In this manner, the mat or pad can provide a relatively inexpensive layer of material that provides shock-absorbing properties and/or a level smooth surface for the carpet to be placed thereon. In the event that a surface has a component extending therefrom, the pad can have an opening cut therein such that the component is nested within the opening and yet still be covered by the covering layer.
In some instances, a floor of a motor vehicle can be carpeted. In the event that a component is mounted to and/or extends from the floor and has a height or thickness not significantly greater or less than the thickness of a carpet pad, the carpet pad can have an opening where the component is nested therewithin and thereby allow for the component to covered by the carpet and still provide an aesthetically pleasing smooth surface.
During assembly line production of machines, for example motor vehicles, reduction of the total number of parts used to manufacture the machine is desired. However, some machines on a given assembly line may have a particular component extending from a body portion of the machine, while other machines on the same assembly line may not have the component extending from the body portion.
In the event that a pad having an opening for the component is installed in a machine that lacks the component, a void or open space is present beneath the covering layer at the opening location. The void or open space may or may not be of functional significance to the machine, but it can result in insufficient structural support to the overlying covering layer and cause an unsightly and/or unsafe depression at this location.
As such, heretofor pads have required one pad having a given part number be provided for machines with the component extending from the body portion and a different pad with a different part number be provided for machines not having the component. This requirement has further resulted in the manufacture, shipment, storage and installation of two separate sets of pads. Therefore, a pad for use under a covering layer that can be used when a component extends from a body portion and when a component is not included, and yet provides structural support for an overlying layer, would be desirable.
The present invention discloses a pad for use under a covering layer. The pad can include a mat with at least one off-all portion, the at least one off-all portion having a puzzle-piece shape. The mat has a bounding portion that is complementary shaped with at least part of the at least one off-all portion, and the bounding portion and the off-all portion have an interference fit therebetween. The interference fit between the bounding portion and the at least one off-all portion provides for the off-all portion to be removably attached to the mat. In addition, removal of the at least one off-all portion from the mat provides an opening for a component to be nested therewithin, while not removing the at least one off-all portion provides structural support to the covering layer that is located over the mat.
The mat can be an underpad located between a layer of carpet and a body portion of a motor vehicle, and in some instances, the mat is an underpad that is located between the layer of carpet and a floor body portion of the motor vehicle. The at least one off-all portion can be part of an outer edge portion of the mat, or in the alternative the off-all portion can provide a puzzle-piece shaped opening within the mat. The mat can be made from a polymer, and in some instances is made from a polymer fiber such as polyethylene terephthalate.
A process for installing carpet in a motor vehicle is also disclosed. The process includes providing a mat with at least one off-all portion, the at least one off-all portion having a puzzle-piece shape and the mat having a bounding portion complementary in shape with at least part of the at least one off-all portion. The bounding portion and the at least one off-all portion have an interference fit therebetween such that the at least one off-all portion is removably attached to the mat. A layer of carpet can also be provided along with a body portion of a motor vehicle to be covered with the layer of carpet.
The process also includes determining if a desired component is extending from the body portion of the motor vehicle at a predetermined location. Thereafter, the process includes removing the at least one off-all portion from the mat if the component is extending from the body portion and leaving the at least one off-all portion removably attached to the mat if the desired component is not extending from the body portion. Thereafter, the mat is extended over the body portion to be covered with the layer of carpet and then the layer of carpet is extended across the mat. In this manner, if the at least one off-all portion is removed from the mat, then the component can be nested within the bounding portion, and if the at least one off-all portion is not removed from the mat, then the at least one off-all portion can provide structural support to the layer of carpet. The component can be a smart sensor that extends from the body portion of the motor vehicle; and in some instances, the smart sensor is a smart key sensor.
The present invention discloses a pad for use under a covering layer. As such, the present invention has utility as a cushioning layer.
The pad can include a mat with at least one off-all portion, the off-all portion having a puzzle-piece shape. For the purposes of the present invention, the term “off-all portion” is defined as a scrap portion of the mat that can be removed from the mat with a pulling action and discarded. The mat has a bounding portion that is complementary shaped with at least part of the at least one off-all portion, the bounding portion and the at least one off-all portion having an interference fit therebetween such that the at least one off-all portion is removably attached to the mat. In this manner, the at least one off-all portion can be removed from the mat and provide an opening for a component to be nested therewithin; or in the alternative, the at least one off-all portion can be left removably attached to the mat, thereby providing structural support to the covering layer that extends across the mat. The use of at least one off-all portion can result in a single mat being installed to cover a surface whether or not the surface has a component extending therefrom. For example and for illustrative purposes only, during the assembly of a motor vehicle, a single mat can be used whether or not a particular motor vehicle has a smart sensor attached to and/or extending from a body portion that is to be covered with carpet.
In some instances, the mat can be an underpad located between a layer of carpet and a body portion of a motor vehicle. In addition, the at least one off-all portion can form or make an outer edge portion of the mat.
A process for installing carpet in a motor vehicle is also disclosed, the process including a mat as described above. In addition, the process includes providing a layer of carpet and providing a body portion of a motor vehicle to be covered with the layer of carpet. After the body portion of the motor vehicle has been provided, the process includes determining if a desired component is extending from the body portion at a predetermined location. Thereafter, the at least one off-all portion can be removed from the mat if the component is extending from the body portion and the at least one off-all portion can be left removably attached to the mat if the desired component is not extending from the body portion. Once the at least one off-all portion has been removed, or not removed, the mat can be extended over the body portion to be covered with the layer of carpet and the layer of carpet can be extended across the mat. In this manner, a process is disclosed that allows for a component to be nested within the bounding portion of the mat, assuming the component is present, or the at least one off-all portion can provide support to the layer of carpet, assuming the component is not present. As such, a single mat can be provided for at least two different assembly scenarios, the single mat reducing the number of components to be manufactured and provided for the assembly of a machine. It is appreciated that the single mat can have a single part number and can reduce the complexity of the design of a machine, the logistics of assembling the machine and the like.
