Patent number: 5753061Abstract: A method for inflating a cushioning devices comprised of at least first and second distinct chambers having an interconnecting passage which provides fluid communication between the chambers. The method comprises either: (1) limiting the volume of at least one of the chambers, filling the chambers with a fluid at a single inflation pressure from a single inflation point and sealing the interconnecting passage, or (2) filling the chambers with a fluid at a single inflation pressure from a single inflation point compressing at least one of the distinct chambers, and sealing the interconnecting passage. The method is particularly suited to manufacture of a footwear cushion comprised of a body of elastomeric material having a plurality of sealed non-communicating cells having a single inflation point. At least two cells sharing a single sealed inflation passage are at different pressures.Type: GrantFiled: June 5, 1995Date of Patent: May 19, 1998Assignee: Robert C.

Patent number: 5543194Abstract: An internally pressurizable lightweight high tensile strength multi-layered structure with an outer barrier layer envelope of elastomeric semi-permeable material for use as a cushioning device is provided. The barrier layer is bonded, at a multiplicity of sites, to substantially the entire distal surfaces of a double-walled drop-thread linked fabric wherein the filaments are a highly distorted, long chain, axially orientated crystalline molecular structure which has a low gas permeability. The bond between the barrier layer and the facing fabric is substantially increased by the presence of fibrils and texturizing. The drop threads which are likewise texturized, function to maintain the composite structure in either a substantially flat or planar or contoured configuration without weldments within the select load-bearing areas. This product is capable of withstanding substantial internal inflation pressures, under long-term steady state and cyclical compression and flexural fatigue conditions.Type: GrantFiled: April 3, 1991Date of Patent: August 6, 1996Assignee: Robert C. BogertInventor: Marion F. Rudy

The outer barrier layer is bonded, at a multiplicity of sites, to substantially the entire distal surfaces of a double-walled drop-thread linked fabric wherein the filaments are comprised of a highly distorted, long chain, axially orientated crystalline molecular structure which has a low gas permeability. The bond between the barrier layer and the facing fabric is substantially increased by the presence of fibrils and texturizing. The drop threads which are likewise texturized, function as stress averaging members to maintain the composite structure in either a substantially flat or planar or contoured configuration without weldments within the select load-bearing areas.Type: GrantFiled: April 4, 1991Date of Patent: January 28, 1992Assignee: Robert C.

Patent number: 5042176Abstract: A product in the form of a cushioning device made from thermoplastic film containing crystalline material inflated to a relatively high pressure and sealed at the time of manufacture. The product maintains the internal inflatant pressure for long periods of time by employing a form of the diffusion pumping phenomenom of self-inflation in which the mobile gas is the gas components of air other than nitrogen. Improved and novel cushioning devices use new material, for the film of the enclosure nevelope which can selectively control the rate of diffusion pumping, thereby permitting a wider latitude flexibility and greater accuracy in the design of such new cushioning device, thus improving the performance and reducing cost of such devices while elminating some of the disadvantages of the earlier products. It is possible to permanently inflate certain types of new devices using readily available gases such as nitrogen, or air in which case nitrogen forms the captive gas.Type: GrantFiled: December 28, 1989Date of Patent: August 27, 1991Assignee: Robert C. BogertInventor: Marion F. Rudy

Patent number: 4906502Abstract: An internally pressurizable lightweight high tensile strength multi-layered envelope is provided. An outer barrier layer of elastomeric semi-permeable material is mechanically bonded at a multiplicity of cites where substantially the entire distal surfaces of a double-walled drop thread linked fabric. The composite structure defines a substantially flat thin lightweight product which is capable of withstanding very substantial pressures.Type: GrantFiled: February 5, 1988Date of Patent: March 6, 1990Assignee: Robert C. BogertInventor: Marion F. Rudy

Patent number: 4287250Abstract: Devices for packaging and/or cushioning products and objects, the devices including permeable elastomeric sheets sealed together at predetermined locations to form separate and discrete chambers, or intercommunicating chambers, inflated initially with a gaseous medium comprising a gas other than air, oxygen or nitrogen which has a very low diffusion rate from each chamber through the elastomeric sheets, ambient air diffusing more readily through the sheets into each inflated chamber to provide a total pressure therein which is the sum of the partial pressure of the air in the chamber and the partial pressure of the gas in the chamber. Not only does the air diffusing into a chamber increase the total pressure therein above the initial inflation pressure of the gas, but the air in the chamber inhibits outward diffusion of the gas from the chamber or compensates for any loss of pressure caused by such outward diffusion of the gas.Type: GrantFiled: January 29, 1979Date of Patent: September 1, 1981Assignee: Robert C. BogertInventor: Marion F. Rudy

Patent number: 4271606Abstract: Shoes incorporating a multiple chambered sole member inflated to a pressure above atmospheric, and disposed above and adjacent to an outsole having a deflectable web and projecting elements, such as ground-engaging studs, depending from the web and disposed in spaced geometric relation to each other to distribute loads imposed on the studs through a greater area of the inflated sole member to a wearer's foot, thereby enhancing its support and comfort.Type: GrantFiled: October 15, 1979Date of Patent: June 9, 1981Assignee: Robert C.

Patent number: 4219945Abstract: A shoe embodying a multiple chambered pneumatically inflated insert encapsulated in a yieldable foam which acts as a bridging moderator filling in irregularities of the insert and providing a substantially smooth and contoured surface for supporting the foot in a comfortable manner. The encapsulated insert can be used as an inner sole slipped into an existing shoe, or it can be used as an integral, composite midsole or outsole portion of a shoe.Type: GrantFiled: June 26, 1978Date of Patent: September 2, 1980Assignee: Robert C. BogertInventor: Marion F. Rudy

Patent number: 4183156Abstract: An improved construction for articles of footwear, such as boots and shoes of all types, includes an inflated insert, preferably in the shape of an insole, having a multiplicity of intercommunicating, gas containing chambers, and a ventilated moderator member which overlies the inflated insole for evenly distributing the forces exerted by the gas containing chambers across the plantar surface of the foot of the wearer. The material from which the insole is constructed and the gas contained in the intercommunicating chambers of the insole member are selected so that the rate of diffusion of the gas through the barrier material of the insole will be extremely slow, the insole remaining inflated to a substantial pressure for several years.Type: GrantFiled: September 6, 1977Date of Patent: January 15, 1980Assignee: Robert C. BogertInventor: Marion F. Rudy
