Abstract
The utility model relates to a means of transport especially suitable for riding or carrying, which mainly adds an additional device comprising the members of a fixing angle rack, a lower connecting rod, an additional wheel carrier device, an upper connecting rod, railings, etc., on the bicycle; three movable connection supporting points are arranged. The means of transport especially suitable for riding or carrying, which is a bicycle, can become a tricycle and carry people. The utility model has the advantages of convenient operation, a simple structure, easy production, and a small size; the additional device can be folded or unfolded as long as one or two sites are released or fastened. The means of transport especially suitable for riding or carrying is favorable to be stored.
Description
The utility model is a kind of vehicle of riding instead of walk or delivering of being specially adapted to.
Ordinary bicycle generally can only be ridden usefulness for a people, and it is then very difficult to carry big slightly object, more can not be with the people; In recent years heteroid trailer formula tricycle occurred, but majority can only separate trailer part and bicycle dismounting, the trailer part is not collapsible and be appended hereto on the bicycle, cause floor area big, deposit difficulty, use inconvenience; Though the form that also has the trailer part to roll over, the complex structure that has, the volume after folding that has is big.
The purpose of this utility model is to design a kind of third round Foldable bicycle, and launching then is three-wheel vehicle, and drawing in then is bicycle, the convenient use.
Can become the bicycle of three-wheel, see accompanying drawing 1, it is made up of bicycle, additional device and a wheel, additional device is installed in the rear portion, right side of bicycle, wheel is installed in the additional device bottom, topmost characteristics be additional device by fixing corner bracket (1), at least two lower links (2), additional wheel carrier, go up members such as frame linking (3) and railing and form.Fixedly corner bracket is a right angle angle Support, and vertical edges all has for being connected, locating and use the hole with horizontal sides, and it is fixed with bicycle rear axle, crossbeam Chain stay respectively with the mounting hole on the vertical edges.Lower link one end and fixedly horizontal sides, the other end and the additional wheel carrier of corner bracket all be rotatably connected (4), (6), lower link and fixedly the corner bracket horizontal sides also have registration device (5).Last frame linking right side and additional wheel carrier are be rotatably connected (7), the left side and fixedly the vertical edges of corner bracket be removably connect (8).Railing is placed in the right side, the back upper lateral part of frame linking, is the fender guard of a man-hour, to guarantee safety.
Additional wheel carrier is made up of wheel carrier (9) and two strut bars (10) at least, and strut bar is fixed on the outer upper of wheel carrier obliquely, and little axle is for connection all arranged on wheel carrier, the strut bar.
Lower link is that an end has with fixing corner bracket and is connected, locatees the hole using hole, the other end to have to match with little axle on the wheel carrier or the rod member of axle sleeve.
Last frame linking is a plane palisade member, the device that left end has with fixedly corner bracket is connected or demolition is used, right-hand member have with strut bar on little the axle hole or the axle sleeve that match.
Railing is made up of back guardrail (11), outer side rail (12), and both have interconnective device.
Fixedly corner fittings is the direct coupled member of additional device and bicycle.Additional wheel carrier is in order to the installation wheel, and the connection fulcrum of frame linking is gone up in formation.Positioning and locking when fixedly the registration device between corner fittings horizontal sides and lower link is used for the additional device expansion.Last frame linking and lower link are to be connected the additional wheel carrier and the fixing member of corner bracket from upper and lower two, form the main body framework of additional device, cooperate and respectively be rotatably connected and demountable structure, last frame linking is connected with fixing corner bracket, then make additional device form rigid body, become three-wheel vehicle, directly loading on last frame linking settles seat cushion then can take advantage of the people; Unclamp then collapsible.When folding, extract locations (5), take off railing, unclamp be connected (8) of frame linking and fixing corner bracket, will go up frame linking around fulcrum (7) laterally rotate 270 ° smooth with additional wheel carrier, to add wheel carrier subsequently and upwards rotate 90 ° around fulcrum (4) together with lower link, when upwards rotating, additional wheel is rotated 90 ° around fulcrum (6), and hang on the bicycle rear rack with hook (13), additional device is close to the trailing wheel outside, becomes folded state.Be still light bicycle.
Adopt the advantage and the effect of this device to be: 1. it is a bicycle, can become three-wheel vehicle again, and it is extremely convenient, reliable to take advantage of people, loading to use; Get loose or fastening one, two places can be rapidly that additional device is folding or launch.2. simple structure is made easily; Volume after folding is little, is beneficial to deposit, and adapts to the needs in current market.
Accompanying drawing 1 can become the bicycle organigram of three-wheel.
Accompanying drawing 2, the A of additional device is to view.
Accompanying drawing 3, the A-A cutaway view.
Accompanying drawing 4, the folded state scheme drawing
As embodiment, see accompanying drawing 1-4, it is 28 vehicles structures, additional device mainly adopts tubing, angle steel and so on manufacturings, together with the heavily about 0.75kg of wheel.Fixedly corner bracket (1) is fastening with nut and bicycle rear axle, adopts clamp, screw retention with Chain stay.Lower link (2) is located with rivet riveting jail in (4) with fixing corner bracket, but rotatable, registration device (5) adopts bolt, nut positioning and locking; The other end adopts axle sleeve structure, cooperates with the little axle of wheel carrier (9) end, adds nut, packing ring is spacing fixing, forms to turn fulcrum (6).When being used for 26 type cars, see accompanying drawing 3, lower link can be moved inward, lower link is connected with the inboard bar of additional wheel carrier, i.e. the long and two-short dash line position.It is spacing fixing that last frame linking (3) also adopts axle sleeve with additional wheel carrier junction (7), little axle adds the nut mode; There are two hooks (14) its below, can hang thereon after railing is pulled down.The frame mode that guardrail adopts the phase interworking to insert connects.
