A scooter includes a frame having a leading end adjacent the front of the scooter and a trailing end adjacent the rear of the scooter, a front wheel mounted adjacent the leading end of the frame, and a rear wheel mounted adjacent the trailing end of the frame. The front wheel is pivotally mounted to a front head set of the scooter frame so as to enable the front wheel to pivot relative to the front head set. The front head set has a longitudinal axis that angles inwardly toward the rear of the scooter so that a lower end of the front head set is closer to the rear of the scooter than an upper end of the front head set. The rear end of the scooter frame has a rear head set that extends along a longitudinal axis that is angled inwardly toward the front of the scooter so that a lower end of the rear head set is closer to the front of the scooter than an upper end of the rear head set.

The invention discloses a liftable mattress. The liftable mattress is characterized by comprising a first mattress portion, a second mattress portion, a third mattress portion and a fourth mattress portion which are connected through a rotating shaft, a soft material wraps around the mattress, an ejector rod is arranged below the third mattress portion, a linkage shaft is connected below the ejector rod, and a rocker rod is arranged on the right side of the linkage shaft. The liftable mattress is reasonable in structure and convenient to use; most comfortable experience can be obtained by adjusting angle of the ejector rod and the first mattress portion; the rocker rod is retracted after use, thereby being free of occupying spare space.

The invention provides a layering device of a compartment and belongs to the technical field of logistics appliances. A situation that the layering device of the compartment is easy to cause rail clamping in the operation process in the prior art is avoided. The layering device of the compartment comprises a supporting plate, two supporting cross beams and main vertical tracks, wherein the supporting cross beams are parallel to each other and arranged in a spaced manner; the main vertical tracks are fixedly connected to the left and right internal side walls of the compartment; locking piecesI slidingly connected with the main vertical tracks are correspondingly arranged at the two ends of each supporting cross beam; the locking pieces I can be located in different height positions on themain vertical tracks; the supporting plate is separately arranged between the two supporting cross beams and can be separated relative to the two supporting cross beams; a connecting component used for supporting the supporting plate is slidingly connected to the internal wall of the compartment; the connecting component can be located in different height positions on the internal wall of the compartment; the supporting plate can move up and down relative to the connecting component; and the front and rear side edges of the supporting plate can correspondingly prop against the two supportingcross beams. The layering device of the compartment has the advantages of smooth operation and stable supporting.

The invention relates to a bed for, in particular to a mother-infant bed for gynaecology and obstetrics. The mother-infant bed can combine a sickbed for a puerpera with a crib and is convenient for the puerpera to take care of an infant, time-saving, labor-saving and capable of relieving burden of the puerpera. The mother-infant bed comprises a base, a first supporting plate, a first bedboard, a lateral protection plate, a big concave plate, a sliding plate, a first bearing, a first rotating shaft and a small bedboard, the first supporting plate is positioned above the base, and the bottom ofthe first supporting plate is connected with the top of the base. The bed is simple and flexible in structure, convenient to adjust, conducive to rest of the puerpera and the infant, easy to produce,manufacture and maintain and safe and reliable in performance.

A motorcycle hitch assembly couples a motorcycle to a trailer allowing the motorcycle to easily turn a corner. A yoke assembly connected to the motorcycle has a kingpin and a cotter-pin. A tow hitch assembly is mounted to the trailer and has an elongated towing arm with a circular socket with an inner spherical surface and a radial ball mounted on and secured to the kingpin by the cotter pin. The radial ball is supported in the circular socket of the elongated towing arm and has an outer spherical surface engaging the inner spherical surface of the circular socket for rotational movement of the radial ball about the kingpin to allow free movement of the motorcycle in various planes while maintaining the trailer in a fixed plane. The circular socket is a one piece construction or a two piece construction.

The invention relates to an elevator, and discloses a multifunctional safe elevator. The multifunctional safe elevator comprises an elevator body and leaning rods. First telescopic rods are fixedly connected with the two ends of the rear side of each leaning rod, and the tail ends of the first telescopic rods are fixedly installed in storage grooves which are formed in the inner wall of the elevator body. A horizontal installation plate is fixedly installed in the middle of each leaning rod, a heating device and a cooling device are symmetrically and correspondingly arranged on the upper sideand the lower side of each installation plate, the output end of each heating device and the output end of the corresponding cooling device communicate with a heat conduction plate through air pipes,and each heat conduction plate wraps the inner side surface of the corresponding leaning rod. A cotton sleeve wraps the outer ring of each heat conduction plate, and a switch is arranged on the lowerside of the middle of each leaning rod. Sitting plate bins are inwards formed in the lower portions of the left side wall and the right side wall of the interior of the elevator body, and a sitting plate is connected with the inner bottom of each sitting plate bin in a rotating mode through a torsion spring. Multiple limiting devices are arranged at the inner bottom of the elevator body at equal intervals. Two second storage grooves are symmetrically formed in the left side wall and the right side wall of the upper side of the interior of the elevator body.
