1. Field of the Invention
The present invention relates to a buffer board, and more particularly to a buffer board for a treadmill. The buffer board uses bamboo strips to be crosswise knitted to constitute a woven bamboo plate, or uses longitudinal bamboo strips connected side by side and transverse bamboo strips connected side by side to constitute a laminated bamboo board, or uses the woven bamboo plate and the laminated bamboo board to be stacked each other. The upper woven bamboo plate or the laminated bamboo board is attached with an endurable slide board. After being applied with a press force, the surface of the endurable slide board is formed with concave-convex massage pattern. The buffer board enhances a buffer effect and provides a foot massage effect.
2. Description of the Prior Art
In general, a conventional treadmill has a buffer board located under a running belt as a support. When the user treads on the running belt, the buffer board bears great applied force. If there is no buffer resilience, the user will feel unconformable. Therefore, an improved treadmill is provided with buffer pads and a buffer device under the buffer board. Besides, a layer of foam is attached on the buffer board and a layer of woven fabric is attached on the layer of foam, providing a smooth turning for a running loop and a comfortable buffer.
The restoration effect of the conventional treadmill is not good, its hardness is great, and the deformation capacity of tread is less. The foot joints of the user may be injured easily when running.
The buffer board of the conventional treadmill is made of hard material, relying on its resilient material, and the buffer pads at four corners of the treadmill are not enough. Therefore, the buffer device is adapted to assist the buffer effect. However, this structure is complicated and the cost is high.
According to a first aspect of the present invention, there is provided a buffer board for a treadmill. The buffer board is mounted under a running belt of the treadmill. The buffer board comprises a bamboo strip portion and an endurable slide plate. The bamboo strip portion is composed of a longitudinal bamboo strip and a transverse bamboo strip. The longitudinal bamboo strip and the transverse bamboo strip are crosswise knitted to constitute a woven bamboo plate. The endurable slide plate is attached on the woven bamboo plate.
According to a second aspect of the present invention, there is provided a buffer board for a treadmill. The buffer board is mounted under a running belt of the treadmill. The buffer board comprises a bamboo strip portion and an endurable slide plate. The bamboo strip portion is composed of longitudinal bamboo strips which are connected side by side and transverse bamboo strips which are connected side by side. The longitudinal bamboo strips and the transverse bamboo strips are stacked to constitute a laminated bamboo board. The endurable slide plate is attached on the laminated bamboo board.
According to a third aspect of the present invention, there is provided a buffer board for a treadmill. The buffer board is mounted under a running belt of the treadmill, and comprises a woven bamboo plate, a laminated bamboo board and an endurable slide board. The woven bamboo plate is composed of a longitudinal bamboo strip and a transverse bamboo strip. The longitudinal bamboo strip and the transverse bamboo strip are crosswise knitted. The woven bamboo plate is attached to the laminated bamboo board. The laminated bamboo board comprises a plurality of longitudinal bamboo strips which are connected side by side and a plurality of transverse bamboo strips which are connected side by side. The laminated bamboo board is attached to the woven bamboo plate. The endurable slide board is attached on the woven bamboo plate.
Preferably, the numbers of the longitudinal strip and the transverse strip depend on the weight and the area of a load.
Preferably, the woven bamboo plate is constituted by one longitudinal bamboo strip and one transverse bamboo strip which are crosswise knitted.
Preferably, the woven bamboo plate is constituted by two longitudinal bamboo strips and two transverse bamboo strips which are crosswise knitted.
Preferably, the woven bamboo plate is constituted by three longitudinal bamboo strips and three transverse bamboo strips which are crosswise knitted.
Preferably, the woven bamboo plate is stacked with at least another woven bamboo plate to constitute a stack of woven bamboo plates.
Preferably, the laminated bamboo board is stacked with at least another laminated bamboo board to constitute a composite laminated bamboo board.
Preferably, the woven bamboo plate and the laminated bamboo board are stacked and then attached with the endurable slide board 2.
Preferably, the endurable slide board on the buffer board is applied with a press force P, such that the surface of the endurable slide board is formed with concave-convex massage pattern according to the pattern of the woven bamboo plate or the laminated bamboo board.
Compared to the prior art, the buffer board of the present invention uses the bamboo plate or the laminated bamboo board or both which are then attached with the endurable slide board to provide a better buffer effect and a foot massage effect.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

Accordingly, the required numbers of the longitudinal bamboo strips 11 and the transverse bamboo strips 12 are analogized by the desired buffer effect. No matter what type of bamboo plate 1′, 1″, 1′″ is generally called a woven bamboo plate 1. Therefore, the at least one longitudinal bamboo strip 11 and the at least one transverse bamboo strip 12 are able to disperse tread impact, providing a balance buffer effect.
