Patent number: 7762008Abstract: The present invention provides articles of footwear adapted for use in extreme and hazardous environments by members of the military, law enforcement personnel and others who require durable and functional footwear. The footwear include protective coverings that may be proof, puncture proof, fire retardant or water repelling. Drainage holes can be positioned in the toe region and along the outsole to enable a wearer to quickly drain water from the article of footwear. Single use or replaceable drainage plugs may cover the holes to prevent entry of water into the boot or other article of footwear. Removable and/or replaceable footbeds may be employed, and such footbeds may provide adjustable sizing of the article of footwear using interchangeable cartridges. A support saddle may be employed with the footbed to enhance foot support under heavy loads. These and other features herein are suited for use in a wide variety of footwear.Type: GrantFiled: September 7, 2006Date of Patent: July 27, 2010Assignee: The Timberland CompanyInventors: Douglas E.

Patent number: 7730640Abstract: The present invention discloses various features and combinations thereof for use with articles of footwear such as boots. The boots are especially adapted for use on construction projects, and provide protection, support and comfort to the wearer. Numerous outsole configurations and styles are provided, which provide superior traction and a low center of gravity for enhanced balance. Different layers of materials provide puncture resistance, abrasion resistance, thermal insulation, waterproofing and other benefits. Protective and/or insulative plates may be utilized in the footwear for puncture protection or thermal insulation, for example. Shovel guards protect the wearer when using a tool, and toe tools permit the wearer to employ the boot as a tool of its own. Structural support cages chimney structures are also utilized for support and comfort.Type: GrantFiled: September 7, 2006Date of Patent: June 8, 2010Assignee: The Timberland CompanyInventors: Douglas E.

Patent number: 7681333Abstract: The present invention provides an interchangeable shoe footbed cartridge system. The system includes a footbed such as a midsole, insole or a sockliner. A cartridge is inserted into or otherwise attached to the forefoot section of the footbed. Multiple cartridges of varying depths, widths and/or lengths may be provided. The wearer can select a cartridge to achieve a desired fit. Because right and left feet may be of different sizes, different cartridges may be chosen for each foot. Furthermore, the user may swap cartridges depending upon different conditions, or to change the stiffness of the cartridge. Additionally, a slipcover having a stretchable portion may be placed over the cartridge system. The cartridges enable a footwear manufacturer to produce fewer shoe sizes while fitting more of the population. This reduces manufacturing, shipping, warehousing and accounting costs. All levels of the supply chain, as well as the end customers, will greatly benefit from the method of supplying footwear.Type: GrantFiled: October 26, 2005Date of Patent: March 23, 2010Assignee: The Timberland CompanyInventors: Alexander Dardinski, John Healy, Peter Dillon, David E. Miller, Simon Luthi, Charles Kraeuter, Douglas E. Clark

Patent number: 7441351Abstract: The present invention provides articles of footwear for use by firefighters in different activities such as emergency and rescue situations, as well as daily activity in and around the firehouse. Integrated handles enable the firefighter to quickly and easily put the article of footwear on while minimizing the possibility of accidentally catching on equipment, apparel or debris. Locking bands that wrap around the upper are used to adjust for comfort and a secure fit. A dual lacing and zipper system enables the firefighter to initially adjust for fit by selectively tightening the lace, while the zipper provides a quick means for securing the article of footwear. Different outsole lug configurations are suitable for different surfaces, wet, dry and of varying and extreme temperatures. Added protection is available with a tibia/shin protector and ankle protectors.Type: GrantFiled: August 17, 2005Date of Patent: October 28, 2008Assignee: The Timberland CompanyInventors: Douglas E.

Patent number: 7347012Abstract: The present invention provides a wraparound lacing system for use with footwear. The lacing system includes a lace which encircles the housing of the article of footwear in a spiral, helical, coiled or similar wound wraparound pattern. The housing includes finger members which independently adjust to the contours of the wearer's foot while providing a snug and secure fit. The housing of the upper and the midsole includes channels therein which receive the wraparound lace. The lace can be affixed at one or both ends to the midsole or to the upper. Removable lace end keepers on the upper permit the user to adjust the length of the lace. Recessed cavities may be positioned along the lacing channels to promote easy adjustment of the lace. The lace may run along channels formed between fingers and an overlying shell structure. The lace may run through a tube structure within the channels.Type: GrantFiled: January 10, 2006Date of Patent: March 25, 2008Assignee: The Timberland CompanyInventors: Douglas E. Clark, Stephen D.

Patent number: 6205683Abstract: A combination insole board includes a shock diffusion plate for diffusing the shock of a heel strike and for providing torsional stiffness in the heel and midfoot areas and includes a flexible material in the forepart of the insole board. The semi-rigid shock diffusion shock diffusion plate is engineered with a contour which loosely correlates to the foot morphology. At least two alternative shoe construction methodologies may be used for incorporating a combination insole board into a shoe according to the present invention. In a first embodiment, the shock diffusion plate is attached to the flexible forepart to form the combination insole board. In this embodiment, the combination insole board is tacked to a shoemaker's last either mechanically or adhesively, an upper having a sufficient lasting margin extending beyond the feather edge is pulled over the last and the lasting margin is attached to the combination insole board with a suitable adhesive.Type: GrantFiled: May 30, 1997Date of Patent: March 27, 2001Assignee: The Timberland CompanyInventors: Douglas E.

Patent number: 5313717Abstract: A reactive energy fluid filled cushioning and stabilizing apparatus in a shoe is comprised of one or more anatomically shaped fluid filled bladders that are positioned in the forefoot, arch and/or heel areas of the shoe. The bladders assume a complementary custom fitting configuration to the contours of a foot inserted in the shoe. In variant embodiments of the apparatus, the fluid filled bladders are positioned separate from each other in the forefoot, arch and heel areas of the shoe and are interconnected in fluid communication by fluid conducting channels, or the bladders are positioned independent of each other in the forefoot, arch and heel areas of the shoe.Type: GrantFiled: December 20, 1991Date of Patent: May 24, 1994Assignee: Converse Inc.Inventors: Bernie Allen, Douglas E.
