Description

Multipurpose combined larry

The utility model relates to a kind of multifunctional combined dolly, is particularly suited for being household supplies.

The dolly that the manpower push-and-pull vehicle particularly uses as family, a lot of now, or manned or loading, both be a kind of of typical case as hand push child car.But, due to itself structure, making it function singleness, application limitation is very big, and structure is also complicated.

The purpose of the utility model is to avoid above-mentioned weak point of the prior art and provides a kind of to be combined by main body car and unit annex, increase and decrease and the change of position or both combinations by the unit annex, combination and split, thus making it to have adapts to multiple application, multifunctional combined dolly simple in structure, easy to use.

Task of the present utility model is to implement according to following technical scheme.It is made up of a kind of main body car and unit annexes such as supporting plate and basket seat that include handle, barre, chassis, wheel.Be characterized in: the chassis of main body car is the keel of " L " type, with before and after on its flat segments and the same plane laterally parallel two wheel frame plates controlling vertical connection placed in the middle become " I " font of symmetry, and pasting movable with it joining of an end and the suitable support of length that the other end can be opened upward in holding in the palm again near trailing wheel frame plate place, keel L-shaped curved section from trailing wheel frame plate place oblique prolong after upwards outstanding; The curved barre that certain angle is arranged in middle part, the one end is placed in the middle to be connected with keel extension outshot with the handle other end that joins; Supporting plate is the removable flat board that is complementary and overlaps with the chassis; The basket seat is one and joins with the activity of main body car and a seat basket of variable present position and dismounting.

Task of the present utility model can also further realize by following approach:

Barre joins in the extension outshot close end activity of itself and keel, and the overlapping with it subsides of suitable long part that are concavity with section are integral, and barre can be folded to front-wheel frame plate direction for axle from contact.

The plate face bottom of supporting plate can be equipped with and can be rolled over the folding leg that subsides can strut again with it.

The composition of basket seat be the semi-circular evagination that is enough to overlap the hook barre on the basket grid point midway by arc with the seat ring of the not closed form of its below outside prominent breach oblique relative up and down, fuse by the basket bar, seat ring connects the ambulatory splint that can be fixed on the bicycle rear rack again down.

The multifunctional combined dolly of one of all schemes as mentioned above, its main body car and supporting plate and basket seat all can make up respectively simultaneously and split is used.

Fig. 4 is support board structure figure

The utility model will be done further statement with embodiment in conjunction with the accompanying drawings:

Embodiment 1:

The multifunctional combined dolly of the utility model, shown in accompanying drawing, the chassis of main body car (3) is by the keel (7) of " L " shape, with its flat segments be in a plane on before and after laterally the parallel front-wheel frame plate of controlling (8) and trailing wheel frame plate (9) vertical connection placed in the middle constitute symmetrical " I " word shape, curved section of keel (7) after trailing wheel frame plate (9) is located, prolong and oblique upward after prolong outstanding.Support (10) is being pasted in two keel (7) pop-ups of taking turns between the frame plate, one end of this support (10) is in locating near trailing wheel frame plate (9) and keel (7) flexible connection, and be that axle makes it and can upwardly open, the seat ring (13) on the opening end bracketing basket seat (6) with the point of connection.This support (10) is the length to opening end from shaft contact, is equal to or less than the distance of shaft contact to front-wheel frame plate (8) inner side edge.Support (10) can be tubulose, rod shape, tabular and oblong or shaft contact be equilateral, the equicrural triangle of vertex position etc. can with the geometrical body of chassis (3), supporting plate (5) coupling.

The middle part of barre (2) is bent to have and is bordering on the curved of the straight angle, the upper end joins between two parties with handle (1), prolonging outshot behind lower end and the keel (7) joins, section from the shaft contact that joins to the bottom is concavity, and overlap to fit with curved section of keel (7) and be integral, causing barre (2) can be folded to front-wheel frame plate (8) direction but can not reflexed.The suitable position of barre (2) bottom on shaft contact leaves radial perforation (18), join with evagination breach (15) activity on the seat ring (13), and cooperates with the support of opening (10), stably hang and hold basket seat (6) so that the same chassis of seat ring (13) (3) is parallel shape.

After adorning, trailing wheel frame plate (9) bottom takes turns (17) preferably cardan wheel.Supporting plate (5) length is equivalent to front-wheel frame plate (8) to trailing wheel frame plate (9) relative inner back gauge, and by the protruding relatively support in medial surface lower end, make front-wheel frame plate (8), trailing wheel frame plate (9), supporting plate (5) be spliced into a plane, supporting plate (5) can be complementary with chassis (3), conveniently detachable one or two flat boards.

Each above-mentioned framing member can be that tubing, section bar, sheet material or their combination that metal, plastics etc. have rigidity and intensity is processed into.

Above-mentioned main body car, additional or additional supporting plate (5) hangs and is stroller when holding basket seat (6) when it.

Embodiment 2:

With reference to accompanying drawing 2, as the multifunctional combined dolly as described in the embodiment 1, when the support on the main body car (10) closure be attached at keel (7), additional supporting plate (5), when basket seat (6) is folded to handle (1) direction, when perhaps also not adding basket seat (6), be baggage car or other load-carrying vehicle of carrying luggage.

Embodiment 3:

With reference to accompanying drawing 4, as the multifunctional combined dolly as described in the embodiment 1,2, the supporting plate of one of its unit annex (5), can strut again at the bottom of can closed being affixed on plate by dress at the bottom of the plate then can be at the main body car during with basket seat (6) composition stroller into the folding leg (11) of leg, and split constitutes one or two little stool.

Embodiment 4:

With reference to accompanying drawing 3, as embodiment 1,2 described multifunctional combined dollies, the structure of the basket seat (6) of one of its unit annex is: by bending on basket grid (12) point midway of arc the evagination semi-ring that is enough to overlap hook barre (2) is arranged, with its with the seat ring (13) of the not closed form of below outside prominent breach (15) oblique up and down relative, by basket bar (14) fusing basket seat (6).Outside the seat ring (13) width of prominent breach (15) just in time embed barre (2) and evagination breach (15) both sides leave with barre (2) on promptly concentric in the same way, same two holes directly of radial perforation (18) so that drift bolt flexibly connects the two.Seat ring (13) is gone up with respect to evagination breach (15) and is located and the activity ambulatory splint (16) that the other end can be locked with evagination breach (15) that joins.

When basket seat (6) and the split of main body car, being fixed in promptly becomes bicycle and carries the seat for children seat on the bicycle rear rack; When it is tangled basket grid (12) with the suspension cable cover, can use the swing seat as again.

The multifunctional combined dolly of the utility model is compared with prior art, has significant excellent part:

Manufacture raw material and draw materials extensively, simple in structure, be easy to make and maintenance; Assembling is convenient with split, by the increase and decrease of unit annex and the change of relative position, and perhaps both combinations, at the same time or separately combination and split and several functions of tool and application; Change with size, it is suitable that child and adult are; Foldable for storage; Be suitable for the condition of the people, required for travel at home load and amusement, the wide future of promoting the use of is arranged.
