Abstract

A scooter footboard comprises a main body (20) and a wooden layer (24) covering portion(s) of the main body. The main body is formed of fiber-reinforced plastic plates and provided in the interior with a receiving space (22).

Description

The present invention relates in a way to

general one

  scooter, and more specifically a scooter footrest.

  A classic scooter footrest is usually made

  of an aluminum alloy or other metal and is therefore light in weight.

  However, the classic footrest is sensitive to significant vibrations when the scooter rides on a bumpy surface. In addition, the classic metal footrest tends to produce

  static electricity due to friction or wind shear.

  In addition, the aesthetics of the classic metal footrest leaves

to desire.

  The main objective of the present invention is to provide a scooter having a light and attractive footrest which is able to

  absorb shock and does not accumulate static electricity.

  In accordance with the principle of the present invention, the foregoing object of the present invention is achieved by a scooter footrest which is formed by a main body of fiber reinforced plastic material and a layer of wood which covers part of the main body. The footrest is able to absorb shocks

and presents the appearance of wood.

  The present invention provides a footrest for a scooter comprising a main body composed of a plurality of plates made of fiber reinforced plastic comprising inside a receiving volume, and a layer of wood covering at least one

part of the main body.

  The footrest may further include a heart made of

  foam and placed in the receiving volume.

  The main body can be made of material

  fiber reinforced thermoplastic impregnated with resin.

  The main body can be made of thermoset material

  fiber-reinforced sand impregnated with resin. The main body can be made of carbon fibers, glass fibers, boron fibers or Kevlar fiber, impregnated with epoxy resin. The thickness of the layer of wood can be between

0.05 mm and 1.0 mm.

  The layer of wood can completely cover the main body.

  pal. Preferably, the footrest further comprises a transparent or translucent protective layer covering the body and the layer of wood, the protective layer being made of plastic material

fiber reinforced.

  The protective layer can be made of plastic material

reinforced with fiberglass.

  Preferably, the receiving volume of the main body has a first inner tube and a second inner tube, which are made of a plurality of plates of fiber reinforced plastic and are fixed together side by side to form a cross rib which divides the receiving volume, said two tubes being

  tightly attached to the main body.

  The first inner tube may include a cavity and a

  shock absorbing body placed in the cavity.

  Preferably, the first inner tube and the second inner tube have a cavity and a shock absorbing body placed in the cavity. The main body may further be provided with a third inner tube placed between the first inner tube and the second inner tube, so that the third inner tube is attached to the first inner tube and to the second inner tube, which results in the

  formation of two cross ribs which divide the receiving volume

tion.

  The third inner tube may include a cavity and a

  shock absorbing body placed in this cavity.

  The present invention will be better understood on reading the

  following detailed description with reference to the accompanying drawings

  preferred embodiment of the present invention.

  As shown in Fig. 1, a footrest 10 produced according to the present invention is mounted on a scooter 12 so that a

  handlebar 14 swivels with the front end of the

  foot 10 and that a rear wheel 18 is pivotally attached to the rear end of the footrest 10. The handlebar 14 is connected

  pivotally with the lower end of the handlebar 14.

  As shown in Figs. 2 and 3, the footrest 10 consists of a main body 20, a layer of wood 24 and a

protective layer 26.

  The main body 20 is constructed in the form of a slightly curved tray and is made of a plurality of fiber-reinforced plastic plates which are rolled together and superimposed so as to provide inside a reception space 22. The body

  main 20 is made of a thermoplastic resin material or therm-

  curable reinforced with fibers such as carbon fibers, glass fibers, boron fibers or Kevlar fiber, impregnated with resin

  epoxy. The main body 20 can be rigid.

  The layer of wood 24 is made of wood or bamboo material and is used to completely cover the main body 20 of

  so as to give the main body the appearance of wood.

  The thickness of the layer of wood 24 is between 0.05 and 1.0 mm.

  The thickness of the layer of wood 24 of the present invention is

0.1 mm.

  The protective layer 26 serves to cover the layer of wood 24 and is made of plastic material reinforced with transparent or translucent fibers, such as glass fiber impregnated with epoxy resin. The protective layer 26 serves to protect the layer of wood 24 against impact. The protective layer 26 is not an essential component of the

present invention.

  The main body 20 is light, flexible, and able to reduce vibrations. The layer of wood 24 has a density different from that of the main body 20 and is therefore able to suppress the transmission of the shock wave. In addition, the layer of wood 24 gives the footrest 10 of the present invention the appearance of wood. In addition, the layer of

  wood 24 avoids the production of static electricity by the footrest 10.

  As shown in Fig. 4, a footrest of the second preferred embodiment of the present invention has a construction fundamentally similar to that of the footrest 10 of the first preferred embodiment, the difference being that the footrest 30 comprises a main body 32 with a volume reception 34 filled with a heart

  36 of plastic foam material such as polyurethane.

  As shown in Fig. 5, a footrest 40 of the third preferred embodiment is of similar construction to that of the footrest 10 of the first preferred embodiment, except that the receiving volume 43 of the main body 42 of the footrest 40 is consisting of a first inner tube 44 and a second inner tube 46, which are made of a plurality of fiber-reinforced plastic plates and are fixed together side by side, resulting in the formation of a cross rib 48 which divides the receiving volume 43. The interior tubes 44 and 46 are also fixed to the main body 42. When the main body 42 is formed, the interior of the main body 42 is provided only with cavities 45 and 47 of the interior tubes. 44 and 46. The outer edge of the connection zone of the inner tubes 44 and 46 and the inner wall of the main body 42 comprise a part 49 of thick wall placed at the two ends of the cross rib 48 and more thick. isse than the other parts. The cross rib 48 and the thick wall portion 49 serve to reinforce the footrest 40. The cavities 45 and 47 can be filled with a

  shock absorbing body 451, 471 made of foam like polyurea-

  Thanne. As shown in Fig. 6, a footrest 50 of the fourth preferred embodiment comprises a main body 52 which comprises in its receiving volume 53 three inner tubes 54, 55 and 56. The main body 52 is therefore provided with two cross ribs 57 and 58 which divide the receiving volume 53, and two parts 571 and 581 of thick wall. The cavity 551 of the central inner tube 55 is

  provided with a shock absorbing body 552.

  The layer of wood of the present invention can be arranged in various ways. For example, the layer of wood 62 covers only the central part of the main body 60, as shown in FIG. 7, or the front and rear ends of the main body 60, as shown in FIG. 8. As shown in Fig. 9, the layer of wood 72 is divided into three parts which serve respectively to cover the front section, the central section and the rear section of the main body 70. As shown in FIG. 10, the layer of wood 76 is divided into three parts which respectively cover the left section, the central section and the right section of the main body 74 in the longitudinal direction of the main body 74. As shown in FIG. 1, the layer of wood 82 covers only the top of the main body 80. As shown in FIG. 12, the layer of wood 86 covers only the edges of the main body 84.
