| 20090174159 | Xtreme street sled - The Xtreme Street Sled is a downhill, steerable sled and is a modification of an earlier application (Application No. 11/067,228 filed Feb. 28, 2005 by David A Brush entitled “Street Sled”, copy attached). The components consist of a two-piece metal frame (steel or aluminum) and a fiberglass covering for each frame piece. The front piece has a steering joint attached to a pole that slides into another larger pole firmly attached to the rear frame. The rear frame is fitted for eight skate board wheels and the front frame is fitted for six skate board wheels. The frame is adjustable in length using the fitted pole. The sled is made for the rider to lie prone facing the direction of motion and has handles on the front portion that stick straight up and allow the rider to hold on to each with hands in the “thumbs-up” position and steer. | 07-09-2009 |

| 20130154212 | FOLD-OUT TRAILER WITH RETRACTABLE WHEEL ASSEMBLY - A trailer includes a trailer frame having a hitch. A stationary support base is joined to the trailer frame. Two support plates are slidably guided on the support base toward and away from each other. A pair of wheel assemblies is provided, wherein a wheel assembly is mounted to an end of each of the support plates remote from the other support plate such that a distance between the wheel assemblies varies with movement of the support plates on the support base. A pair of drive links is provided wherein a drive link is joined to each of the support plates. A drive mechanism is joined to the drive links and configured to selectively move the support plates toward or away from each other. | 06-20-2013 |
| 20130214500 | UNIVERSAL SKI CONVERSION DEVICE FOR A STROLLER OR BICYCLE TRAILER - A ski conversion device for a stroller or a bicycle trailer including: wheel braces for attachment to first and second skis and for receiving the first and second wheels; connecting elements for fixing the wheels to wheel braces; orientation braces for attachment to skis; orientation elements for connecting the stroller or the bicycle trailer to the orientation braces and for fixing an orientation of the stroller or the bicycle trailer with respect to the skis; a rigger element for connecting to a ski and including a runner element; and yokes for connection to the skis, the yokes attachable to a source of energy for propelling the ski conversion device. In a first position, the runner element is locatable between the first and second skis. In a second position, the runner element is locatable beyond the first ski in a direction from the second ski toward the first ski. | 08-22-2013 |
| 20130277925 | Wheelbarrow Sled System - An accessory is provided for a wheelbarrow. The wheelbarrow has: a wheel; a tray; a pair of handle members supporting the tray relative to the wheel and extending rearward past the tray; and a pair of legs for cooperating with the wheel to support the wheelbarrow in a parked condition.
