Description

Saddle skeleton and leather pad combined structure for bicycle

The utility model relates to a kind of parts of bicycle, exactly, relates to a kind of need not the to be provided with seat cushion framework of bicycle of extra metallic combination hook accessory and the unitized construction of leather packing.

Now, the ordinary bicycle seat cushion all is to be made of on the top layer of skeleton outside face and the main parts in addition such as elastic cushion block that are clipped between skeleton surface and the epidermis seat cushion framework, cladding.Because seat cushion framework must could constitute complete seat cushion finished product with the leather packing combination, therefore, must adopt relevant combining device that both are fixed together.Referring to Fig. 1, the seat cushion that uses mainly is made of skeleton 10 and leather packing 20 now, and wherein leather packing 20 has the flange 21 of an invagination, and it is adjacent to the inner peripheral surface 11 of skeleton 10, gives clamping with a metal clip again.The metal clip takes the shape of the letter U, and opening up.One side edgefold 31 abuts in the inner peripheral surface 11 of skeleton, and with rivet 32 whole clip 30 is fixed on the internal face of skeleton, and the top of another flanging 33 of clip is provided with zig-zag.

During assembling, earlier the invagination flange 21 of leather packing 20 is filled in the U-shaped opening of clip 30, after the clip for the treatment of whole circle was all inserted the invagination flange, the flanging 33 with clip pressed down again, makes the sawtooth top 33 engaging-in leather packings of this flanging, finishes the combination of leather packing 20 and skeleton 10.

This seat cushion that is combined into has following shortcoming: (1) must use extra metal clip 30, and this other part also needs operations such as punching, bending except that wanting punch forming, make bothering.(2) need the clip that uses at least more than 10 on each seat cushion, also need one by one riveted quite expends man-hour on skeleton.(3) clip this as U-shaped, but factory wants earlier clip is evened up when making, and puts into when with instrument nail being riveted over assembling again behind the rivet and bends, formality is loaded down with trivial details during assembling.In a word, the very complicated trouble of the traditional seat cushion framework and the combination of leather packing, manufacturing cost improves relatively, has reduced the market competitiveness.

The purpose of this utility model provides the combine and assemble structure of a kind of new bicycle seat cushion framework and leather packing, to overcome the defective of prior art.

The utility model is achieved in that and is provided with a plurality of integrated crotches week in seat cushion, a gap is arranged between the end of this crotch and the inside face of skeleton; The corresponding section of crotch therewith on the invagination flange of leather packing is respectively equipped with the suitable hole slot of size; Invagination flange by the stretching leather packing makes the flange part in its hole slot outside sandwich in the formed curved mouth of crotch of seat cushion framework from above-mentioned gap location, and makes the hole slot of leather packing clamp crotch.

The utility model has the advantages that: whole seat cushion need not use extra metal clip and rivet fully, and the preparation of relevant metal clip and need put into rivet, in addition riveted, folding all can omit relevant man-hour flat, the press-bending clip repeatedly.And the combine and assemble of the skeleton of this new structure and leather packing, quite convenient, rapid, can shorten man-hour greatly, increase productivity, thus reduce production costs, help promotion.

Specifically introduce characteristics of the present utility model and effect below in conjunction with accompanying drawing, embodiment.

Fig. 1 looks External view in the end of traditional seat cushion.The position of one of them metal clip is partly to cut the invagination flange of leather packing open exhibition to look.

Fig. 2 looks External view in the end of the utility model embodiment.

Fig. 3 is the front elevation of the utility model embodiment Fig. 2.

Fig. 4 is the part sectional view of the utility model embodiment disjunctor crotch.

Fig. 5 is a leather packing on the utility model Fig. 4 embodiment cover, and makes the invagination flange of leather packing prepare the schematic sectional view that combine and assemble is carried out in the stretching location.

Fig. 6 is the continuation of Fig. 5, even the scheme drawing that leather packing and skeleton assembling finish.

Consult Fig. 2, Fig. 3, Fig. 4, the utility model also is the seat cushion that is made of bicycle use seat cushion framework 4 and leather packing 5, be characterized in: along the inner peripheral surface 50 of skeleton 4 lower hems, be provided with the crotch 40 that a plurality of one are extended, this crotch 40 is after stretching out the upper hem 41 of suitable distance from internal perisporium basically, roll over (shown in Figure 4 is last folding direction) vertical edges 42 downwards along this upper hem 41, a crooked hook portion 44 is formed on the bottom 43 by vertical edges again, makes suitable gap 60 of inner peripheral surface 50 maintenances of end 45 with the skeleton of crooked hook portion 44.And on the invagination flange 51 of leather packing 5, all be respectively equipped with the slotted eye 52 of suitable size with above-mentioned extension crotch 40 corresponding places.

Consult Fig. 5, Fig. 6, the folding flange 51 of leather packing 5 is the inner peripheral surfaces 50 that are attached to skeleton 4 earlier, because leather packing 5 all is to make with elastomeric material, so, can cross flange 51 surface of the vertical edges 42 of crotch 40 earlier, the application of force is with its elongation (as shown in Figure 5) again.When being pulled through crotch 40 Deng the front end of flange 51, therefore the flange 53 that is drawn as hole slot 52 outsides that slightly enlarge just enters in the gap 60 of formation between crotch 40 and the inner peripheral surface 50.When tensile force discharged, the flange 53 in the outside will be because of the elastic restoring force retraction crotch 40 formed curved mouthful of inside of material itself, and 52 in its notch is clamped the upper hem 41 of crotch just.

Because the whole interior fitfull arc that is in week of seat cushion framework 4, the equidistant a plurality of crotches 40 that distribute on it, after being snapped into the hole slot 52 of leather packing invagination flange,, forcing leather packing 5 to be fitted by close positioning and finish assembly with skeleton 4 because of its swollen power of drawing kayser that is subjected to different directions.

Seat cushion framework 4 of the present utility model is provided with a plurality of integrated crotches 40, and on the invagination flange 51 of the corresponding crotch position of leather packing 5, all be respectively equipped with the hole slot 52 that matches, when making assembling, as long as the invagination flange front end of leather packing 5 is stretched a little, just can make the Outboard Sections 53 of flange enter gap 60, promptly assembling is very simple, convenient and rapid.
