Description

Bicycle hollow seat cushion

This creation is related to seat cushions, especially about a hollow seat cushion for bicycles.

Generally, a bicycle seat cushion includes a body and a cushion body overlying the body. The cushion body can be made of foam materials with different softness or thickness according to usage requirements to increase the comfort when riding. In addition, the conventional seat cushion may be additionally provided with a shock absorbing spring located under the body or an inflatable bladder located inside the seat cushion to increase the cushioning effect. However, the body needs to have a large surface width to provide sufficient installation space, resulting in an increase in the weight of the seat cushion, and the spring also increases the overall weight, which is not conducive to weight reduction; the seat cushion with an inflatable bag needs Multiple components are assembled with each other, the structure is complex, which leads to difficult processing and increased manufacturing costs.

Therefore, it is necessary to provide a novel and progressive bicycle hollow seat cushion to solve the above problems.

The main purpose of this creation is to provide a hollow seat cushion for bicycles with simple structure and good cushioning effect.

In order to achieve the above purpose, this creation provides a bicycle hollow seat cushion, including: a lower cushion body; and an upper cushion body, combined with the lower cushion body, which is softer than the lower cushion body, defines a long axis center line and defines A plurality of chambers located on two sides of the central axis of the long axis, the plurality of chambers are independent and not in communication with each other, and each of the chambers is open to one side of the upper pad body after passing through the central line of the long axis; wherein the upper pad The body defines two sides located on two sides of the centerline of the long axis, and each side is provided with at least two chambers.

The following only uses examples to illustrate the possible implementation of this creation, but it is not intended to limit the scope of this creation to be protected, which will be described first.

Please refer to FIGS. 1 to 5, which show a preferred embodiment of this creation. The bicycle hollow seat cushion 1 of this creation includes a lower cushion body 10 and an upper cushion body 20.

The lower cushion body 10 is made of, for example but not limited to, metal or plastic, and can provide sufficient supporting force; the upper cushion body 20 is combined with the lower cushion body 10, and the upper cushion body 20 is softer than the lower cushion body 10, The upper cushion body 20 defines a long axis center line A and defines a plurality of chambers 21 on both sides of the long axis center line A. The plurality of chambers 21 are independent of each other and are not in communication with each other, and each of the chambers 21 is open to the One of the upper pad bodies 20 passes through the long axis center line A and the rear side 22; wherein the upper pad body 20 defines two side portions 23 located on both sides of the long axis center line A, each side portion 23 is provided with at least two室室21. Thereby, the plurality of chambers 21 can be used for gas circulation, and the cushioning effect is good, and the structure of the hollow seat cushion 1 of the bicycle is simple and easy to manufacture and process.

At least one of the plurality of chambers 21 is integrally closed annularly in the circumferential direction, and the sealing is better. The extension lengths of at least two of the chambers 21 of each of the side portions 23 are different. Preferably, they can have different extension lengths according to the outer contour of the upper cushion body 20, and the cushioning effect is better. Since the weight that the upper cushion body 20 bears decreases from the long axis center line A toward the two side portions 23 and from the rear side 22 forward, at least two of the extension lengths of the chambers 21 of each side portion 23 Preferably, the direction of the long axis midline A decreases toward the outside, at least two of the chambers 21 of each of the side portions 23 extend in parallel, and the radial dimension of each of the chambers 21 tapers away from the rear side 22 As shown in FIG. 5, the plurality of chambers 21 can provide a buffer space corresponding to the magnitude of its force, which has good shock absorption effect and comfortable use. Of course, the extension length of each of the chambers can also be the same or the configuration of the extension length and the radial dimension can be changed according to requirements; each of the chambers can also be non-parallel extensions or intersect with each other. Furthermore, in a cross section of the thickness direction of the upper cushion body 20, the radial dimension of each chamber 21 is not less than 1/6 of the thickness of the upper cushion body 20, which can provide sufficient gas flow space and reduce The shock effect is better.

The hollow seat cushion 1 of the bicycle further includes a plurality of nozzles 30 which are harder than the upper cushion body 20, and one of the nozzles 30 is inserted at one end of each of the chambers 21 to prevent the deformation of the end of each chamber 21 from being stressed It is not conducive to the circulation of gas. A radial flange 31 is provided at each end of each nozzle 30, one of the flanges 31 of each nozzle 30 is inserted into one of the chambers 21, and the other flange 31 abuts on the rear side 22. Can be stably connected without falling off. In this embodiment, each of the flanges 31 is embedded in an inner peripheral wall of the chamber 21, which has good stability. At least one of the shape, cross-section, and plane of the ports of at least two of the plurality of nozzles 30 are different; the lengths of at least two of the plurality of nozzles 30 are different, which may correspond to the surface profile of the rear side 22 With different lengths and curvature changes of the ports, as shown in FIGS. 2 and 5, the appearance is better and it is not easy to be hit by foreign objects.

Furthermore, the upper cushion body 20 may include an upper portion 24 for human contact and a lower portion 25 integrated with the upper portion 24. The material, color or surface structure of the upper portion 24 and the lower portion 25 may be different. For example, the upper part 24 may have a smooth surface, for example, which is more comfortable to use; the lower part 25 may have a rough surface or a different color from the upper part 24, with different visual effects, and better aesthetics.
