Abstract: A foldable stroller frame having right and left front, right and left rear legs, and right and left handle supports joined at a right and left folding joints in a manner permitting folding movement about a folding axis between deployed and folded positions. A seat panel connects the front legs and includes a movable portion being movable between first and second positions. A seat back frame is connected to the movable portion at a seat back pivot. Spacing between the seat back pivot and the folding axis is dependent upon the position of the movable portion. When in the first position, the spacing is greatest and precludes frame folding due to interference between the seat back frame and a transverse element between the handle supports. When in the second position, spacing is minimized and frame folding is permissible without interference between the seat back frame and the transverse element.

A connecting tube extends between the air tube and the valve stem, the connecting tube having an internal connecting air passageway for directing air forced along the air tube air passageway into the internal valve stem passageway as the tire rolls over a ground surface.

Abstract: A spoke 15 has a spoke crest 15a, a spoke radially outer wall 15b and a pair of spoke circumferential side walls 15c. In a cross section of the spoke 15 along a radial direction of a disk, a crest outer curved portion 15a2 of the spoke crest 15a is curved at a larger curvature than curvatures of a crest inner curved portion 15a1 of the spoke crest 15, a crest main portion 15a4 of the crest and the spoke radially outer wall 15b. Thus, compared with a conventional one, a configuration of the spoke 15 becomes like a box. As a result, a bending strength and a bending rigidity of the spoke 15 in the radial direction of the disk can be improved.

Abstract: A hybrid vehicle includes an engine, a front module, a drive wheel, a transmission, a case, an oil inlet, a return passage, and a bypass passage. The case has a first chamber accommodating the front module, and a second chamber accommodating the transmission. The second chamber includes an oil pan. The oil inlet is arranged inside the oil pan. The return passage communicates the first chamber with the second chamber. The return passage keeps a first oil level inside the first chamber higher than a second oil level inside the oil pan by applying flow resistance to oil. The bypass passage is arranged at a position higher than the first oil level when the hybrid vehicle is in a horizontal position and lower than the first oil level when the hybrid vehicle is leaning forward at a predetermined angle.

Abstract: The present disclosure relates to snowboards and skis that include a pair of edges for each longitudinal side of the snowboard or ski. The edges are laterally spaced apart, with one edge being an outer edge and the other edge being an inner edge. The inner edge is positioned vertically lower than the outer edge. The inner edge generally engages the snow surface prior to the outer edge, and is thus a transitional edge. Transitional edges may be rounded edges. The top surface of dual-edges snowboards or ski include an inner portion flanked on each lateral side by a lateral offset. A portion of the inner portion is recessed relative to the lateral offsets. The outer edges are positioned on a base surface of the lateral offsets. The inner edges are positioned on a base surface that is below the interface between the lateral offsets and the inner portion.

Abstract: A powertrain for a vehicle and a method of assembling the powertrain are disclosed. An engine includes a crankshaft being rotatable about a longitudinal axis. A ring gear is attached to a first distal end of the crankshaft such that the ring gear and the crankshaft are rotatable in unison about the longitudinal axis. A starter mechanism is selectively operable to rotate the ring gear and the crankshaft to start the engine. A motor-generator includes an adapter selectively cooperating with the starter mechanism to dispose the motor-generator and the starter mechanism in alternative assembly configurations being a first assembly configuration and a second assembly configuration. The first assembly configuration is when the starter mechanism is coupleable to the adapter and the second assembly configuration is when the starter mechanism is spaced from the adapter to operate independently of the motor-generator.

Abstract: A three wheeled scooter comprises a chassis having forward and aft ends with a front wheel non-pivotally mounted to the forward end and a pair of rear wheels coaxially mounted to the aft end. The chassis defines a longitudinal axis and includes a support assembly and a handle assembly extending upwardly from the support assembly. The rear wheels are configured to be angularly yawable relative to the longitudinal axis between a neutral position and a yawed position. Steering of the scooter is thereby effectuated by angular yawing of the rear wheels relative to the longitudinal axis such as by asymmetric loading of one of opposing sides of the support assembly.

The hub cover is rigidly secured to a wheel hub and maintains the axial position of the axle shaft. A shock absorber may be positioned between the drive fingers and the drive slots. The axle shaft may be formed from a hollow tube or a solid shaft by cutting an end portion of the shaft and deforming a cut section radially outwardly to form a drive finger.
