Abstract

The utility model relates to an improved structure of a bicycle seat pad. The hollow middle part of a frame of a seat pad is formed with a pressure bearing seat, a clamping rod is arranged on the frame at the front end of the hollow part, the back end of the hollow part is provided with a clamping seat, and an elastic element is provided with spring strip branches which are connected by a webbed board. The front end of the elastic element is collected with a high-strength tensile board, the board is provided with a through hole clamped with the clamping rod, and the tail ends of spring strips are inlaid with attached head and cooperated with the clamping seat of the frame. The seat pad can not deform due to long-term load bearing after pressed, and the utility model has the advantages of favorable flexibility and comfort, good air permeability and practicality.

Description

Improved structure of cycle saddle

The utility model relates to the technical field that a kind of bicycle chair cushion improvement structure belongs to bicycle accessory.

General bicycle chair cushion, its seat cushion framework is mostly by the plastic cement injection mo(u)lding, constitute by single plate body, and have complete upper surface and sit sincere for the human buttock, its appearance more is coated with elastic body foam material and tight bundle cortex top layer, the foam material thickness is limited, and buttocks just felt to press hard rather than soft traveling comfort when user's seat was pressed on the very hard seat cushion framework, felt not ideal unavoidably.Traditional bicycle chair cushion is owing to have smooth upper surface on the skeleton, thereby actual uses that to go up area of contact bigger, and not having any guide channel can provide convenience for ventilative, the sitting chair cushion will cause and the cortex top layer between frictional heat, more feel uncomfortable.

Traditional seat cushion coats cortex mainly by skeleton body, between Jie pointing elastic foam and topped in the periphery of support body 1 with the bulk shape full wafer that cooperates seat cushion.This class cushion is kept the buffering and shock preventing that liner elastic force between top bearing surface and human buttock depends on elastic element 3 entirely in the use and is absorbed; use skeleton body of a specified duration slightly directly stressed; regular meeting chaps; damage; shortcoming such as be not durable; and aeration is relatively poor, and human buttock's sitting utmost point sense thereon is stiff and sultry, makes the people produce human discomfort.

Permanent deformation can take place not only to make outward appearance not attractive in appearance, and pliability and shock-absorbing elasticity are more reduced through the human body weight effect of exerting pressure for a long time down in elastic element.

The purpose of this utility model is the improvement structure that a kind of bicycle chair cushion will be provided, and it can overcome above-mentioned shortcoming, and is simple in structure, guarantees good air permeability, takes advantage of a person to feel soft comfortable.

The purpose of this utility model is achieved in that seat cushion framework middle part hollow out becomes Pressure Block, the skeleton at hollow-out parts front end place has kelly, rear end has the attached seat of card, each blocks, and attached seat all has bigger empty portion to fill out to cut open and the retaining neck of the bundle plate body that contracts, block attached seat bottom and be provided with base plate, elastic element has several springs to branch off row mutually, there is paddle blade to link again, the spring front end accumulates strong extending board, open-work is set on the plate, is interlocked, but the spring head end there is the attached head of embedding inlay card in the attached seat of card with kelly, spring thickness of slab height makes greater than paddle blade thickness and forms ventilative ditch between the spring, and the occupant can not have sultry sensation.

Fig. 1 is the scheme drawing of original bicycle chair cushion.

Fig. 2 is the STRUCTURE DECOMPOSITION figure of bicycle chair cushion.

Fig. 3 is the three-dimensional outside drawing of bicycle chair cushion.

Fig. 4 is the lateral plan of bicycle chair cushion.

Fig. 5 is the lateral plan of the running condition of bicycle chair cushion.

Now in conjunction with the accompanying drawings the structurally improved structure of bicycle chair cushion is described in detail.

By Fig. 1, cushion comprises skeleton body and coats cortex, elastic foam is housed therebetween.

Fig. 2, this chair cushion is made up of seat cushion framework 10 and elastic element 20, the external form of seat cushion framework 10 has the arcuate surfaces that accords with the ergonomics moulding, the middle part hollow out becomes a landing district 26, in close hollow-out parts front end place, skeleton 10 has three kellies 11, and the rear end forms 5 attached seats 12 of the uncovered cards that make progress, the attached seat of each card 12 has filling out of bigger empty portion and cuts open 27 and the retaining neck 28 of the bundle plate body that contracts, and is provided with base plate 13 and block attached seat 12 bottoms;

Elastic element 20 has several springs 21 to branch off row mutually, and has paddle blade 22 to link, and each spring 21 front end compiles becomes a strong extending board 23, and it is corresponding with kelly 11 that 3 open-works 24 are set on the plate.The end of each spring 21 has the bar head to enlarge attached 25 of the formed embedding of shape.Spring 21 thickness of slab height make and form ventilative ditch between each spring greater than paddle blade 22 thickness.

Fig. 3 is the three-dimensional outside drawing of bicycle chair cushion.

When seat cushion framework 10 and elastic element 20 combinations, be to utilize plastic cement to penetrate extrusion forming method prefabricated elastic element 20 is placed in seat cushion framework 10 forming dies, penetrate and extruding cooling be combined into by plastic cement, at this moment kelly 11 is fastened in the open-work 24, attached 25 equal inlay card of the embedding of each spring 21 combined closely in the attached seat 12 of card.

Fig. 4 is the lateral plan of bicycle chair cushion.

Elastic element 20 is filled up in landing district 26 in the present embodiment, and the occupant can feel soft traveling comfort.

Fig. 5 is the lateral plan of bicycle chair cushion running condition.After (cutaway view) elastic element 20 pressurizeds, its spring 21 and paddle blade 22 all are pressed down and elastic deformation take place, yet spring 21 and paddle blade 22 have the drop on the height, rely on it last liner the foam material and coat the compression that the cortex (not shown) forms a vacuum pump, make paddle blade 22 upper surface air-guide groove spaces because of its squeezing action absorbs fresh air, make the face surface of taking advantage of that the characteristics of ventilative cooling be arranged.

Compared with prior art, bicycle chair cushion improvement structure has following advantage:

1. improve on the structure, be rich in the elastic force of pliability more.

2. seat cushion good air permeability, the occupant does not have stiff sultry human discomfort.

3. the structure of elastic element reason pressurized and permanent deformation takes place not.

4. cost is low, and is simple in structure.
