20110027008 | MODULAR CRANKSHAFT - In accordance with certain embodiments, a modular crankshaft features a connection system between modules that features opposed female receptacles. A pin having opposed beveled ends and hydraulic passages with it is inserted into the opposed receptacles. A pair of seals is disposed on the beveled ends and straddles a hydraulic fluid outlet. The crankshaft wall that defines each receptacle is designed to flex in response to applied hydraulic pressure between the seals on the tapered pin portion. A notch at the base of the receptacle in the crankshaft reduces stress concentration and enables the wall defining the crankshaft receptacle to come back when hydraulic pressure through the pin is removed. The opposed crankshaft receptacles are flanged to allow them to be pulled together over the pin. An interference fit results around the pin after the flanges are mated and the hydraulic pressure is removed. | 2011-02-03 |
20110027009 | SUSPENSION RESTRAINT SYSTEM - A suspension restraint system for an All Terrain Vehicle (ATV) includes a clamp fixed to at least one control arm of a suspension system, a rod mount fixed to a frame member, a rod configured to be secured to the rod mount. The rod is configured to engage said clamp and restrain the movement of the suspension system when the suspension system is in a lowered position relative to the frame member. | 2011-02-03 |
20110027010 | STROLLER AND ADJUSTING MECHANISM THEREOF - A stroller includes a handle switchable between a front inclined position and a rear inclined position, an article holding accessory, and at least one adjusting mechanism. The adjusting mechanism includes a sleeve component secured to the handle, an axle ring component connected to the article holding accessory and coupled rotatably to the sleeve component, and a positioning plate. The axle ring component has first and second engaging parts corresponding to the front and rear inclined positions, respectively. The positioning plate is coaxially secured in the sleeve component and has a positioning part engageable with a selected one of the first and second engaging parts with respect to an axis of rotation of the axle ring component, so as to provide a substantially horizontal position of use for the article holding accessory when the handle is at either one of the front and rear inclined positions. | 2011-02-03 |
20110027011 | CONSTRUCTION TECHNIQUE FOR A DOMESTIC APPLIANCE SUCH AS A SURFACE CLEANING APPARATUS - An appliance or domestic apparatus such as a surface cleaning apparatus comprises a first part and a second part. The second part comprises an insertion portion slidably insertable into the first part to define an inserted position. The insertion portion comprises a longitudinal axis and a first detent member. A movable lock is slidably mounted on at least one of the first part and the second part, and is slidable at an angle to a longitudinal axis of the insertion portion. The movable lock has a second detent member. When the insertion portion is in the inserted position, the first detent member positioned inwardly of the second detent member, and the second detent member is selectively positionable to interact with the first detent member to lock the first part to the second part. | 2011-02-03 |
