Specific embodiment
As shown in Figure 1, small handcart 100 has substantially quadrangular type frame 110.The rectangular shape is by apart one
Two longitudinal framing parts 112 that set a distance extends in parallel and extend in parallel at a distance from each other and with two longitudinal framing parts
112 connected two transverse frame members 111 formation.There can be the frame unit 111,112 of rectangular section to weld together and formed
The pedestal of rectangle.
Two rotary casters 120 are mounted at one end (that is, front end) of frame 110, and are mounted under frame 110.Two
A rotary caster includes wheel body 121, which is rotatably coupled in fork 122, which rotates further through wheel plate 113
Formula is connected on frame 110.The rotation axis of wheel body 121 is horizontal, and the rotation axis of fork 122 is vertical.Also
It is to say, the rotation axis of wheel body 121 is orthogonal to the rotation axis of fork 122.Wheel plate 113 is maintained at frame by reinforcing rod 118
On frame 110, which extends in the space as defined by frame 110.Design shown in Fig. 1 is longitudinally reinforced comprising two
Bar 118, they support the inner end of corresponding wheel plate 113, which also includes 3 transverse reinforced bars 119, two of them across
Between longitudinally reinforced bar 118, another is across between longitudinal framing part 112.
Two rigid castors 130 are arranged at the opposite end relative to rotary caster 120 of frame 110, and are arranged
Under frame 110.The wheel body of rigid castors is aligned with the side of small handcart (rear side) forever, according to the embodiment, the side
For longitudinal direction side.
The top side tool of small handcart 110 is there are two race 116, for receiving the rotary wheel 120 of the folded small handcart 100 set
Corresponding wheel body 121, the top side of small handcart also has there are two race 117, for receiving the rigid castors of the folded small handcart 100 set
130 corresponding wheel body.Therefore, 120,130 pairs of castor in the opposite side (that is, bottom side) of race 116,117 and frame 110
Together.For receive rigid castors 130 wheel body race 117 by the upper surfaces of fork of rigid castors 130, small handcart 100
The rear portion of frame 110, and the transverse reinforced bar 119 of most rear side are limited.The reinforcing rod 119 of most rear side also serves as to be added to be longitudinal
The installation point of the rear end of strong bar 118.
Bottom for receiving the race 116 of the wheel body 121 of rotary caster 120 is formed by wheel plate 113.Race 116
Side is formed by frame 110 (especially longitudinal frame unit 112).116 another aspect of race is limited by wheel body supporting element 114
It is fixed.Wheel body supporting element 114 can be the item of a metal, plastics, composite material or other suitable materials, be configured to be formed
A part of race 116.In an illustrated embodiment, wheel body supporting element 114 is arc.Wheel body supporting element 114 is from frame 110
Longitudinal framing part 112 inner surface on front side point backward side point extend.The central area of the arc and longitudinally reinforced bar
118 are in contact.The lower section of wheel body supporting element 114 is supported by wheel plate 113.Wheel body supporting element 114 may be welded to wheel plate 113, frame
On frame 110 and/or reinforcing rod 118.Therefore, wheel body supporting element 114 on wheel plate 113 by transverse frame member 111 and longitudinal
Extend in space defined by frame unit 112.
In folded set, the rolling surface for folding the wheel body 121 of the small handcart 100 set touches wheel plate at the bottom of wheel body
113, and wheel body supporting element 114 is touched at the higher circumferential edge of rolling surface.Race 116 may also include the second contact
Point connects for higher relative to bottom contact point and between wheel body supporting element 114 and the rolling surface of wheel body of wheel body
The opposite rolling surface in contact is in contact.According to a not shown embodiment, the second contact point is by the groove type on wheel plate
At being configured to be consistent with the shape of the rolling surface of wheel body.According to shown embodiment, the second contact point is by screw
The formation of head of screw 115, which is connected to the fork 122 of rotary caster 120 on frame 110.Head of screw 115 be configured to
The shape of the rolling surface of wheel body is consistent.Particularly, head of screw 115 may include being in contact for the rolling surface with wheel body
Inclined or arc side surface, including bevel-faced form, concave form, convex form or other appropriate forms.Head of screw 115 exists
The contact surface of wheel body is supported on contact point between wheel plate 113 and wheel body.As shown in Figure 1, with 114 phase of wheel body supporting element
Than, head of screw 115 closer to frame 110.
The structure proposed allows this small handcart 100 more easily to stack.Fig. 2 shows four identical small handcarts
100 stacking, wherein suffix A to D shows the sequence of stacking.Fig. 3 a to Fig. 3 c shows how wheel body supporting element 114 is permitted
Perhaps the wheel body 121B stacked has a variety of different orientations.Fold the wheel body 121B (referring to fig. 2) of the small handcart 100B set no
Can only have portrait orientation (referring to Fig. 3 a and Fig. 3 c), can also turn an angle towards the rotation axis relative to castor
Between angle position (referring to Fig. 3 b).Therefore, the angle that the wheel body supporting element 114 of arc is conducive to castor is freely orientable.
