| 20080271345 | BOOT ARTICULATION SUPPORT SYSTEM - The present invention relates to a support system for use in relation to an articulation region of a boot. Embodiments of the present invention relate to a boot with a dorsal metatarsal articulation region that allows for articulation in the sagittal plane such as a telemark ski boot. One embodiment of the present invention relates to a telemark ski boot, including a shell, an articulation region, and an articulation support system. The articulation support system includes at least one tensile rigid region extending transversely between the proximal and distal sides of the articulation region. The tensile rigid region impedes rotation of the rear portion of the shell about the toe portion in a frontal plane. This form of rotation is often referred to as torsional rotation. The articulation support system may include one or more of a cable, an integrated shell portion, a material mesh, and/or other tensile rigid components which maintain bending flexibility. A second embodiment of the present invention relates to a method for increasing the torsional support characteristic of a telemark ski boot while maintaining the desired flexibility. | 11-06-2008 |
| 20090113763 | MODULAR BOOT SOLE SYSTEM - One embodiment of the present invention relates to a ski boot system with a modular binding interface. The system includes a shell encasing a user's foot and lower leg. A first and second block are interchangeably coupled to the shell below the base to effectuate alternative binding interfaces. The first and second blocks include a binding interface surface and a sole surface. The positioning and shape of the blocks with respect to the shell results in the binding interface surface extending distally from the toe region of the shell and the sole surface being the lowest surface on the boot system. The binding interface surfaces for each block are positioned at different sagittal heights with respect to the shell to facilitate the interconnection with alternative binding coupling systems. The sole surfaces for each block are positioned at substantially identical sagittal heights with respect to the shell to maintain optimum and consistent performance characteristics among different bindings. | 05-07-2009 |
| 20090113764 | SELECTABLE BOOT ARTICULATION SYSTEM - One embodiment of the present invention relates to a ski boot system including an upper shell, lower shell, and an articulation system. The upper and lower shell function to enable a user to move their encased foot in various dimensions/orientations corresponding to anatomical supination, pronation, dorsiflexion, and plantarflexion. The articulation system selectively affects the articulation freedom between the upper and lower shells in locked and unlocked configurations. The articulation system includes a lower shell coupler and an upper shell coupler coupled to the lower and upper shells, respectively. The locked configuration of the articulation system includes engaging the upper and lower shell couplers to restrict freedom between the upper and lower shell. The lower shell coupler is coupled within a recess in the lower shell that substantially restricts movement to a single orientation corresponding to coronal rotation. | 05-07-2009 |
| 20090320327 | SELECTABLE BOOT SUPPORT AND ARTICULATION SYSTEM - The invention generally relates to a selectable boot articulation and support system. One embodiment of the present invention relates to a boot system including an intercoupled upper and lower shell configured to encase a user's foot and lower leg. The boot system further includes an articulation system effecting the articulation between the upper and lower shell. The articulation system includes an instep member coupled and positioned with respect to the upper shell in a manner that facilitates selection between a locked configuration and an unlocked configuration. The unlocked configuration provides increased articulation and decreased stiffness between the upper and lower shell with respect to the locked configuration. The instep member may include a releasable dorsal coupling between portions of the upper shell. The instep member may also include one or more moveable lateral couplings with the upper shell. | 12-31-2009 |
| 20110138586 | WIRE-GATE CARABINER - One embodiment of the present invention relates to an improved wire-gate carabiner system including a frame, gate, and gate biasing system. The gate is pivotably coupled to the frame across an opening to form a continuously enclosed inner region in a closed configuration. The gate may be referred to as a wire-type gate in that it includes an arch and two ends. The arch is looped over a hook disposed on the keyed region of the frame in the closed configuration. The two ends are pivotably coupled to the frame at two independent gate coupling points on the pivot region so as to utilize the torsional rigidity of the gate structure as the gate biasing system. The keyed region of the frame includes a hook and a cover. The cover is oriented and shaped to laterally shield the arch and hook from undesirable couplings. | 06-16-2011 |
| 20110284321 | ADJUSTABLE HARNESS LEG LOOP - The present invention relates to adjustable harness leg loops. One embodiment of the present invention relates to a harness leg loop system comprising a first and second leg loop intercoupled with one another at respective coupling points. The first and second leg loops include interior regions within which a user's leg may be disposed. The areas of the interior regions are individually selectively adjustable via respective slidable members disposed between the interior region and the coupling point of each leg loop. The selective adjustability of the interior region areas does not substantially affect the rise between the interior regions and the coupling points. The minimum shear strength of the interior regions is independent of the slidable members. Therefore, if one of the slidable members fails, an object coupled through the interior region will not necessarily break free from the interior region. | 11-24-2011 |

| 20100031747 | SCOOP HAVING A PARKING ANCHOR FOR MEASURING AND DISPENSING POWDERED OR GRANULAR MATERIAL - A scoop for measuring and dispensing powdered or granular material has at least one projection, such as a fin, multiple intersecting fins, or a spike, which enable the scoop to be “parked” in the surface of a powdered or granular food product without the handle of the scoop coming in contact with the product. The projection is preferably molded unitary with the scoop and handle. Unless the container is vigorously shaken, dropped, or subjected to extreme accelerative or decelerative forces, the scoop will remain in its parked position until the container is reopened for a further dispensing of the powdered or granular food product. The scoop may be packaged as an assembly in combination with a discardable floating scoop retainer disk, that is placed on the surface of the granular or powdered product, and prevents the scoop from sinking below the surface during shipping and handling. | 02-11-2010 |
| 20110224585 | KNEE REHABILITATION DEVICE - A knee rehabilitation device is provided which can be used in various stages of knee rehabilitation to facilitate a full range of knee motion and promote joint flexibility following a knee impairment. The device, which can be can be used by a patient with or without the aid of medical personnel, is simple to use, compact, and is highly adjustable to accommodate different therapy regimens, and different leg sizes. To achieve maximum stretch of affected tissues of a pathologic joint, the device can be used without the need of lower extremity muscle involvement. A first embodiment device is machined or cast from a lightweight structural metal, such as titanium, aluminum or magnesium. The device includes a handle of adjustable length that is rotatably coupled to a parallel-beam leg support. The leg support provides attachment points for multiple adjustable slings that bridge the gap between the parallel beams. | 09-15-2011 |
