Similarly, the second outer layer 16, alternatively called the bottom outer layer 16 includes an outside surface 19 and an inside surface 17. The outer layers 12, 16 offer a waterproof layer of protection to the inner layers 20, 35 of the material 10.
Either surface 13, 14 of the top outer layer 12 or either surface 17, 19 of the bottom outer layer 16 may further receive a coating. The coating may be comprised of polymeric material such as Linear Low Density Polyethylene (LLDPE), High Density Polyethylene (HDPE), or Low Density Polyethylene (LDE).

Any polymeric material capable of being dispersed, dispensed, etc as a coating may be used as a coating in accordance with the method of the present invention.
The coatings can increase the strength of the material 10. Further, any color can be used for the coatings for different applications. For example, the top surface 13 of the top outer layer 12 may receive a black coating. For certain applications, the black coating will increase the heat retention of the material 10. Similarly, the bottom surface 14 of the top outer layer 12 may receive a silver, or similar reflective, coating. The silver, or reflective, coating would aid in reflective capability of the material 10. Thus, a silver coating could be placed on various surfaces 13, 14, 17, 19 of various layers 12, 16 depending on the application and the direction towards which the additional reflective qualities are desired. Likewise, a white coating could be placed on various surfaces 13, 14, 17, 19 to enhance reflective qualities of the particular layer to which it is adhered to.
The bubble layer 20 includes a top surface 21 and a bottom surface 22 with an approximate plane of a plurality of bubbles 23 therebetween. The plurality of bubbles 23 may be sized in any standard bubble sizes (e.g., ¼″, ½″, ¾′, etc.) or any custom bubble sizes.
Alternatively, the insulation layer 20 may be closed-cell foam insulation made from materials such as closed-cell polyethylene foam, polypropylene foam, and the like.
The inner layers 20, 35 are adhered in some fashion to at least one of the outer layers 12, 16. In the embodiment shown both inner layers 20, 35 are adhered to each other and to the respective adjacent outer layer 12, 16. For example, the metallic layer 35 is adhered to both the inner surface 14 of the top outer layer 12 and to the top surface 21 of the bubble layer 20. Similarly, the bottom surface 22 of the bubble 20 is adhered to the inner surface 17 of the bottom outer layer 16.
The term, adhered, as used herein means that the two, or more, layers of material are attached to each other via a heating and melting process wherein the two layers of material have different melting temperatures and upon the heating of one, or both, of the adjacent layers results in a adhesion between the two material layers in the area wherein the heat was applied, and subsequent melting has taken place.
The term, adhered, further means that the two, or more layers, are adhered in the region wherein the heating of the one, or both, layers took place. Thus, while the entire area of a layer may be heated, it is not necessary for the entire area of the layer to be heated. For example, instead of heating the entire layer area, a smaller portion, or section, of the layer may be heated. This would result in the smaller portion, or section, being adhered. Further, the heating to the requisite melting temperature may be applied in a particular pattern on a layer. One example, may be only heating a perimeter boundary of the layer. In this manner, only the perimeter boundaries of the layers will be adhered. Another example, includes heating nearly the entire area of the layer with the exception being a certain shaped pattern, wherein no heat is applied. In this manner, the at least two layers will be adhered nearly fully except for the area of the shaped (i.e., non-heated) pattern.
The embodiment shown in
It should be apparent to one skilled in the art, that numerous configurations are attainable wherein at least one closed-cell insulation layer 20 is adhered with a top outer layer 12 and a bottom outer layer 16 thereby providing a reinforced adhered insulation material 10. The material 10 can be configured in, virtually, any size, shape, and configuration. For example, the material 10 can be made in sizes like a blanket, or tarpaulin. Material 10 made in these sizes would be convenient for applications such as concrete curing covers, shipping blankets, under-concrete slab waterproof membranes, waterproof layers, and the like. The embodiments could be generally fixed in shape and size.
Alternatively, the size and shape of the material 10 may be user-selectable. That is various means can be incorporate into the material 10 so as to allow the user to parcel out the desired shape and/or size for the particular application.
The further advantage of the adherence properties of the material 10 allow for the user to further cut, punch, tear, etc. the material 10 into any shape and size without the disadvantage of any of the layers becoming unadhered.
An additional feature can be provided with the material 10 wherein, as shown in
It should be apparent that, while the compression regions 50 are shown along the periphery of the material 10, other locations and configurations of compression regions 50 are obtainable. For example, compression regions 50 could be interspersed either longitudinally, or transversely, along the material 10. Compression regions 50 may be symmetrical or asymmetrical about either axis. Various patterns (e.g., checkerboard, lines, crossing, diagonal, etc.) of compression regions 50 can, likewise, be made.
Similarly, different width compression regions 50 can be made. Thus, while the bearing surface 202 in
Further depicted in phantom is a post-manufactured opening 65 of arbitrary shape. This opening 65 may be made by the user with manual or automated means (e.g., knife, scissors, blade, etc.). Alternatively, the opening can be made by a machine (not shown).
It should be apparent that virtually any shape, size and pattern of perforation 40, holes 60, or post-manufactured opening 65 may be may be provided on either a compression region 50 or a non-compression region of the material 10. Ultimately, the perforation 40, hole 60, or post-manufactured opening 65 may result in an opening 70. As with the a tear, abrasion, and/or puncture in the material 10, the construct of the material 10 is such that the opening 70 will not provide a region for delamination of the layers of material 10 due to their adherence.
An advantage of the invention, as shown in this embodiment (See
In
It should be apparent that although the opening 70 through the material 10 is shown along the material 10 in an axial fashion, openings 70 may be made in any location, or any pattern on the material 10. Further, the openings 70 can be made either in a compressed area 50 or a non-compressed area (i.e., “field”) of the material 10.

An embodiment of a wall port device, or apparatus, herein denoted by 300 is shown in perspective view in
The port extension 330 includes an element 340 at, or near, the distal end 332. The port extension 330 has material 333 that extends from the proximal end 331 to the distal end 332. The element 340 may provide a surface feature 341, 342 by being enclosed within, or attached to, the material 333. The material 333 may be any suitable material that is flexible, semi-flexible, rigid, or semi-rigid. For example, the material 333 may be vinyl, fabric, plastic, metal, composite, or any other suitable material. The term flexible herein is to mean pliable, or semi-pliable. The port extension 330 may be of variable lengths extending away from the wall portion 310. It may come in standard lengths. For example, the length of the port extension 330 may be approximately 4″ to 10″ in length. Should the extension 330 be made of flexible, or semi-flexible material, this allows the axis 390 to be adjustable by the user. This enhances the ability of the user to readily and easily attach a duct to the device 300.
The element 340 may fully, or partially surround the perimeter of the port extension 330. The element 340 may be made of steel or other suitable rigid material to provide a spring bias, snap fit, or other functional engagement due to variations in diameter between the outer periphery of elements 340 and 502. The element 340 may be a hoop. The element 340 may be connected to the material 330, for example, by being sewn within a sleeve at, or near, the distal end 332. Should the material 333 be rigid, or semi-rigid, for example, the element 340 may be omitted in its entirety.
The cross section of the port extension 330 may be circular, as shown in the embodiment in
The wall portion 310 has a front surface 311 and a back surface 312. Extending through the wall portion 310 is the opening 320. The opening 320 may include a mesh 321, or similar filter material, across the opening 320 that is suitable in size and type for preventing the passage of objects (not shown) across the opening 320. For example, the mesh 321 may be made of nylon suitably sized to act as a bird screen. The mesh 321 can prevent trash, debris, leaves, children, or other objects from passing through the opening 320.
On both the front surface 311 and back surface 312 may be a cover 313a, 313b. The covers 313a, 313b are accessible from the front surface 311 and back surface 312, respectively. They allow the user to unfurl the cover 313a, 313b and cover the opening 320, if desired, when the device 300 is not in use. Thus, the cover 313a, 313b is of suitable non-porous material such as vinyl, fabric, and the like. When either cover 313a, 313b is not in use, they may be rolled up and retained via a retainer 315. The retainer 315 may be any suitable means such as a hook and loop fastening system located, as required, on portions of the cover 313a, 313b and front surface 311 and back surface 312.
Similarly, the cover 313a, 313b may also include a portion of a hook and loop system 314a on its perimeter while a portion of the wall portion 310 has a complimentary portion of a hook and loop system 314b. This hook and loop system 314a, 314b allows for the cover 313a, 313b when in use to be more securely attached to the wall portion 310 thereby providing a weather tight capability. In lieu of the hook and loop system 314a, 314b, other quick-release attachments for the cover 313a, 313b may be employed. For example, zipper(s), snap(s), button(s), and the like (not shown) can be used to ensure that the cover 313a, 313b stays attached to the wall portion 310.
The wall portion 310 may also include a plurality of attachment elements 318 that are suitable for further attaching the wall portion 310 to another structure 410 (See e.g.,
On both the front surface 311 and the back surface 312, spaced on the perimeter of the opening 320, are a plurality of D-rings 323. The D-rings 323 provide an additional attachment point for connecting various elements together.
The view depicted in
The device 300 in its entirety, or just individual elements (e.g., wall portion 310, material 33, cover 313, etc.) may alternatively be made of the aforementioned reinforced adhered insulation material 10.
Turning to
As can be seen in greater clarity in
Various types of duct 500 may be attached to the device 300. The duct 500 can have various uses as will be discussed below. The duct 500 may be of a flexible material such as coated vinyl. A flexible, spiral wound duct 500 is shown in
As the impending attachment is shown in
The manifold box 410 includes a plurality of devices 300a, 300b, 300c located on various surfaces of the box 410. The box 410 further includes a removable hatch 402 that allows access to the interior of the box 410. Each of the devices 300a, 300b, 300c includes a port extension 330a, 330b, 330c that allows a first end 505a, 505b, 505c of the ducts 500a, 500b, 500c to connect thereto in the aforementioned fashion. Thus, the dog 520 may enter at any of the second ends 506a, 506b, 506c of the various ducts 500a, 500b, 500c and travel through the ducts 500 and box 410. Clearly, additional structures 400 and ducts 500 may be added to provide a plurality of system arrangements.
