Description

The collapsible seat for children of bicycle use

Technical field

The utility model relates to a kind of seat for children that is installed on the bicycle rear rack, the collapsible seat for children of especially a kind of bicycle use.

Background technology

The widely used children's of carrying baby chair on bicycle great majority are monolithic deviceses on the market at present, and it is more easy to store therefore to take up space when temporary transient leaving unused, and the user is caused trouble.Maker for baby chair on bicycle is all the more so, not only the stock is needed more space, also can account for the more space of transportation means in transit, and this was both uneconomical, also can improve the manufacturing cost of seat for children.In addition, the bent angle portion of the foot-operated hanging box of baby chair on bicycle and the junction of underframe is an area of stress concentration, very easily fractures, especially Wan Pi children, scrunch, twist foot-operated hanging box frequently repeatedly, how long just do not damaged, it is also very dangerous that this not only influences use.

Summary of the invention

The utility model is for solving the collapsible seat for children of long-lived bicycle use that takes up space less when the technical matters that exists in the known technology provides a kind of depositing.

The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:

The collapsible seat for children of a kind of bicycle use, by underframe, the rear vertical frame of underframe back, the underframe front vertical frame that has handrail in front, two lateral vertical frames that open wide the place are left on the underframe both sides, the preceding bottom plate of going up of the connection bicycle rear rack on the underframe is gone up bottom plate with the back, be hinged on upper mounted plate two ends, back can before and after upset can seal or open the two unlimited active catch frames of locating, and the foot-operated hanging box of installing on two unlimited underframes of locating and preceding upper mounted plate is formed, described underframe is made of preceding underframe and back underframe two parts, the junction of preceding underframe and back underframe is hinged with two jointed shafts, underframe and back underframe are at conplane limitting casing before the hinged place of preceding underframe also has a maintenance: described rear vertical frame is to be hinged on by two jointed shafts on the underframe of back, the hinged place of back underframe also has a limitting casing that prevents that rear vertical frame from turning over: described two lateral vertical frames are that a front takes the shape of the letter U, the framework that the side is L-shaped, its two open end is hinged on the underframe dual-side of back by two jointed shafts, the U-shaped base of framework is just riding over the after-frame upper limb, at the after-frame upper limb clamp of fixing this U-shaped base is housed also; Described antero-inferior fixed tray is

The spacing that is connected the corner of the foot-operated hanging box on the shape, its length and the preceding upper mounted plate of underframe before two are installed in equates.

Advantage and the good effect that the utlity model has are: because the whole underframe of seat for children is divided into forward and backward two parts form that is hinged, it is hinged that after-frame and two side frames all are shaped on each limit of trailing portion of jointed shaft and underframe, whole seat for children can be folded up, it takes up space is original 1/3, to the user deposit with manufacturer stock, transportation all be very easily.The antero-inferior fixed tray that seat for children will be installed is made in addition

Shape has been limited the swing of foot-operated hanging box, has eliminated the stress concentration that connects the corner, has prolonged the service life of seat for children, reaches convenient, durable purpose.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1, underframe is made up of preceding underframe 1 and back underframe 3 two parts, has jointed shaft 2 that they are linked together between the forward and backward underframe, for underframe before making and after underframe in same plane, and certain steadiness is arranged, be shaped on a limitting casing 21 at the jointed shaft place of preceding underframe.Also be shaped on the front vertical frame 11 that has children's handrail 10 in the front of preceding underframe, front vertical frame and preceding underframe can be made one, and be more firm like this, also easily processing.Jointed shaft 4 hinged installation rear vertical frames 5 are passed through in back at back underframe 3, turn in order to prevent rear vertical frame, also are shaped on limitting casing 41 at the jointed shaft place of back underframe, can only make rear vertical frame 5 folding forward like this, and can not turn over.The lateral vertical frame of back underframe both sides is bent by a root timber material and forms, it is shaped as the front and takes the shape of the letter U, the framework 6 that the side is L-shaped, its two open end are hinged on back underframe dual-side by two jointed shafts 8 respectively, and the base of U-shaped just in time stably rides against the upper limb of rear vertical frame 5.In order to make framework 6 more firm, on the upper limb of rear vertical frame, be shaped on a clamp 7, block the U-shaped base of framework 6.For seat for children can be installed on the bicycle rear rack, upper mounted plate 12 and back upper mounted plate 9 before being welded with respectively on preceding underframe and back underframe are installed on the bicycle rear rack 18 by fabricated section A, B, consult Fig. 2 and Fig. 3.Fabricated section A is made of antero-inferior fixed tray 15 and screw 14: fabricated section B is made of back bottom plate 16 and screw 17.Concrete mounting structure is, is installed on the bicycle rear rack 18 seat for children is fastening by antero-inferior fixed tray 15, screw 14 and back bottom plate 16, screw 17.In order to increase functions of use, also be hinged with at the two ends of back upper mounted plate 9 can forward and backward upset active catch frame 91, with the unlimited place of this closed on both sides, when belongings, avoid article to drop like this from opening wide.The both sides of preceding underframe 1 are opened wide the place two foot-operated hanging boxes 13 also are installed.Foot-operated hanging box one end is to be plugged under the upper mounted plate of back, and the other end is to be installed on the preceding underframe, as shown in Figure 5 by screw 14 and antero-inferior fixed tray 15 (together fixing when seat for children is installed).Because foot-operated hanging box and preceding underframe bonded assembly corner are that area of stress concentration 19 is easy to produce fracture by fatigue, antero-inferior fixed tray 15 are made for this reason Shape, its length will with two foot-operated hanging boxes be connected that distance equates between the inboard, corner, fixedly the time, make it tightly abut in the medial surface of two foot-operated hanging boxes, thereby limited the swing to the inside of foot-operated hanging box, play the effect of reinforcing foot-operated hanging box, the destruction of having reduced counter stress concentration zones 19 has like this prolonged service life.

Using method:

When the bicycle folding seat for children is temporarily idle, at first will ride hanging box 13 and active catch frame 91 is pulled down, and then with its from the back clothes hanger 18 unload, clamp 7 is thrown off on the base of the U-shaped framework 6 of two side frames, then rear vertical frame 5 is turned to forward on the underframe 3 of back, last turn over preceding underframe 1 on the U-shaped frame of two side frames together with the front vertical frame 11 of Armrest 10 more simultaneously in again the U-shaped frame 6 of two side frames the is turned over back of back underframe.So just institute takes up space and narrows down to 1/3 originally, as shown in Figure 4.
