| 20090200762 | Assembly for Towing a Wheeled Stroller on Sand - An assembly and method for adapting a baby stroller to better travel over unstable ground, such as sand. A sledge is provided that has a top surface and a bottom surface. The bottom surface is flat with a beveled front end that enables the sledge to be easily pulled over sand or mud. Retention features, such as semi-cylindrical depressions, are formed in the top surface of the sledge. The retention features enable a baby stroller to be placed atop the sledge without rolling off. Once the wheels of the stroller are attached to the sledge, the sledge can be pulled through sand and mud more easily. The sledge may be supported by wide wheels to help the sledge roll over unstable ground. Furthermore, the sledge may be collapsible so that it can be easily stored when not in use. | 08-13-2009 |

| 20130285337 | ALL TERRAIN SLED - An all-terrain sled that allows a user to easily pull cargo over any terrain. The sled includes a bottom shape that provides, with forward movement, lift over soft terrain. Cut out areas in the bottom of the all-terrain sled reduce surface drag by minimizing contact area. A leading edge of the cut out area may be disposed with an angle that can move soft surface material, such as sand, into the cut out area. A trailing edge of the cut out area may be disposed with an angle that can provide lift for the sled when moving it forward while guiding the material out to the side of the sled. The sled may include wheels on each side at one end of the sled for ease of movement over smooth terrain. | 10-31-2013 |

The cooler includes an insulated body having an inner compartment defined by a bottom wall having side walls extending upwardly therefrom, and a lid hingedly attached at the open upper portion of the body. The body further includes a bottom portion having a pair of rear wheels. In one embodiment, the device includes a sled arrangement. In another embodiment, the device includes a ski arrangement. The ski arrangement includes a pair of skis that may be removably attached to the bottom of the cooler. The sled or ski arrangement of the present invention are preferably attached to the bottom portion of the body, and in front of the rear wheels. In this way, the present invention provides a convenient way to transport a cooler to different locations by preventing the rear wheels from getting stuck on various terrain. | 03-26-2015 |

An example ambulation aid apparatus includes an ambulation aid body formed as a integral part, the integral part formed in monocoque construction to provide support for mobility of a user through the integral part, the integral part providing a plurality of grippable areas to facilitate user movement and support through the integral part. Another example ambulation aid apparatus includes a primary panel formed in monocoque construction to provide support for and assist in mobility of a user through the skin of the monocoque primary panel, the primary panel formed to interrelate with one or more subassemblies to provide an integrated monocoque part to assist in providing support for and improved mobility of the user through the integrated monocoque part. Example methods of manufacture are also disclosed and described. | 06-30-2016 |
| 280009000 | Retracting wheel or runner | 10 |
| 20090309320 | Ski equipped with a collapsible undercarriage device - A ski equipped with a collapsible undercarriage device including: a ski, an undercarriage carrier and a collapsible undercarriage device, wherein the collapsible undercarriage device has wheels upon arms which can be folded and deployed, enabling safe skiing when the arms are folded and carrying the ski upon the ground, which can be snowed, with assistance of the wheels, when the arms are deployed and with another ski optionally connected to it. | 12-17-2009 |
| 20100201087 | Retractable Wheel System for Snowmobile Ski - The present invention provides a retractable wheel system for snowmobile skis. The retractable wheel system of the present invention may be installed on a snowmobile ski without affecting its structural integrity by installing the system on the reinforced portion of the snowmobile ski. When a user circulates in a path with little or no snow, the retractable wheel system is positioned in the extended configuration by the user and the system will automatically return to the retracted configuration when the user returns in a snowy zone. This is realized by using a pre-tensioned spring that will reposition the wheel in the retracted configuration. The spring transmits a rotational movement to the member on which the wheel is fixed. | 08-12-2010 |
| 20110181006 | TRAILER CONVERTIBLE TO A SLED - A trailer convertible to a sled uses a drop axle, which is mounted for rotation. The drop axle has a sled mode and a trailer mode. Upon rotation of a primary shaft of the drop axle in a first direction, ski supports lower skis into the sled mode and secondary shafts supporting wheels are raised. Upon rotation of the primary shaft of the drop axle in a second direction, the ski supports raise the skis and the secondary shaft supporting wheels are lowered to the trailer mode. A lock is provided for locking the drop axle in a selected one of the sled mode or the trailer mode. | 07-28-2011 |
| 20120181758 | Retractable and automatic positioning wheels for snowmobiles - A device allowing positioning of wheels of a snowmobile when skis leave a snowy path to continue on a road. The device comprises at least two parallel wheels positioned near each ski, a pair of cylinders placed in connection with each wheel, and controlled by a control box by a driver activating pistons to move the wheels from an upward position to a downward ground position. The upward position corresponds to wheels elevated over the ski when the piston is contracted; and the downward position corresponds to wheels in touch with the ground when the piston is extended. Means of clutch move horizontally the wheels to an external position. A spike located on an arm which supports a wheel is positioned to scratch ground ice for creating a mist when a wheel is in a scratching position. | 07-19-2012 |
| 20140054868 | WHEEL-UNIT-READY SKI FOR SKI-MOUNTED VEHICLE - A snowmobile ski adapted to accommodate wheel units that are movable between a deployed position and a stowed position. The floor of the ski has one or more wheel openings to allow wheels to drop down to the deployed position. A wheel unit may have a single wheel or two wheels in tandem. The wheel units may be mounted on the kingpin, the side wall, inner ribs, or on the steering spindle. | 02-27-2014 |
| 20150123360 | Wheel-Unit-Ready Ski for Ski-Mounted Vehicle - The invention is a snowmobile ski that is adapted to accommodate wheel units that are movable between a deployed position and a stowed position. The floor of the ski has one or more wheel openings, which allow wheels to drop down to the deployed position. A wheel unit may have a single wheel or two wheels in tandem. The wheel units may be mounted on the kingpin, the side wall, inner ribs, or on the steering spindle. A snow guard is provided on the ski body, to prevent snow or ice from hindering operation of the wheel unit. | 05-07-2015 |

| 20150290055 | ANTI-TIPPING SAFETY DEVICE - An electromagnetic anti-tipping device uses electromagnets to steady users and prevent falls by persons with impaired mobility and balance. The device's steadying effect is accomplished by magnetically attracting the legs and/or wheels of balance and mobility assisting apparatus (“balance and mobility aid(s)”) to a stationary surface such as a floor which is made of or covered with a magnetically responsive material. In one embodiment, the device's electromagnet attraction to the floor or other stationary surface is actuated when the operator of the device triggers the device's mechanism or sensor by grip or touch. Once actuated, and until deactivation by the user, the device's electromagnet(s) secure the legs or wheels of the balance and mobility aid to the magnetically responsive floor or other stationary surface. The electromagnets are battery-powered. | 10-15-2015 |
| 20150360710 | SKI ATTACHMENT FOR A PORTABLE COOLER - A ski attachment device for a portable cooler is disclosed.
