DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Figs. 2 to 4, a preferred embodiment of a steering device according to the present invention is adapted to be used in a surfboard 2. The surfboard 2 has a board body 21 that has a head 23 and a tail 24, and a power unit 22 that is mounted to the tail 24 for propelling the board body 21. The power unit 22 is configured as a jet pump having a water outlet 25 that opens rearward. The steering device includes a steering unit 3, a driving unit 4, and a transmitting unit 5.
The steering unit 3 is adapted to be coupled pivotally to the power unit 22, and is operable for controlling a moving direction of the board body 21.
5 The driving unit 4 includes a hollow base seat 41, a linking member 42, a drive seat 43, a drive arm 44, a bearing 45, and a handle 46. The base seat 41 is adapted to be secured fixedly to the head 23 of the board body 21. The linking member 42, in this embodiment, is formed as a plate, is disposed in the base seat 41 and is rotatable about a driving axis (D). The drive arm 44 is elongated and defines a longitudinal axis, and has a connecting end and an access end. The connecting end is registered with the driving axis (D). The access end is opposite to the connecting end along the longitudinal axis and extends outwardly from the base seat 41. The drive arm 44 is substantially untwistable and is rotatable about the longitudinal axis for driving rotation of the linking member 42 about the driving axis (D). The drive seat 43 extends along the driving axis (D) and interconnects the connecting end of the drive arm 44 and the linking member 42 (i.e., the connecting end of the drive arm 44 is connected to the linking member 42). The bearing 45 is interposed between the base seat 41 and the drive arm 44. The handle 46 is secured fixedly to the access end of the drive arm 44.
Referring to Figs. 4 and 5, the drive arm 44 of the driving unit 4 has a flexible tubular wall 441 and a plurality of angularly spaced apart steel cables 442 that extend along and that are embedded in the tubular wall 441. In this embodiment, the tubular wall 441 is made of rubber. Each of the steel cables 442 is composed of a plurality of steel strands, or may have only one steel strand. The drive arm 44 has a torque tolerance along the longitudinal axis thereof within 5 degrees, which makes the drive arm 44 substantially untwistable.
The handle 46 of the driving unit 4 is ring-shaped, and has a holding section 461 substantially perpendicular to the longitudinal axis of the drive arm 44 at the access end of the drive arm 44.
Referring back to Figs. 2 to 4, the transmitting unit 5 interconnects the linking member 42 and the steering unit 3 such that the rotation of the linking member 42 about the driving axis (D) drives pivot operation of the steering unit 3 via the transmitting unit 5. The transmitting unit 5 includes a sleeve 51, a cable 52, a driving steering lever 53, and a driven steering lever 54. The sleeve 51 is adapted to be secured to the board body 21 and has opposite ends adjacent respectively to the driving unit 4 and the steering unit 3. The cable 52 extends through the sleeve 51 and has opposite ends.
The driving steering lever 53 is connected to one of the opposite ends of the cable 52, and the driven steering lever 54 is connected to the other one of the opposite ends of the cable 52. The driven steering lever 54 has a distal end that is opposite to said other one of the opposite ends of the cable 52 and that is connected pivotally to the steering unit 3. The driving steering lever 53 has a distal end that is opposite to said one of the opposite ends of the cable 52 and that is connected pivotally to the linking member 42.
Referring to Figs. 3, 6 and 7, the steering unit 3 includes a fluid-guiding tube 31 that is connected pivotally to the power unit 22, that is adapted to be disposed in fluid communication with the water outlet 25 of the surfboard 2, and that is connected pivotally to the distal end of the driven steering lever 54 so that the rotation of the linking member 42 about the driving axis (D) in a rotational direction drives the fluid-guiding tube 31 to rotate in an opposite rotational direction.
To change the moving direction of the surfboard 2, as shown in Fig. 6, an operator standing on the board body 21 holds the holding section 461 of the handle 46 and rotates the drive arm 44, so that the linking member 42 spins in a first rotational direction (R1).
Consequently, the driving steering lever 53 is moved and moves move the driven steering lever 54 via the cable 52, thereby driving the fluid-guiding tube 31 to pivot in a second rotational direction (R2) opposite to the first rotational direction (R1). On the contrary, referring to Fig. 7, when the drive arm 44 is rotated to drive the rotation of the linking member 42 in the second rotational direction (R2) , the fluid-guiding tube 31 is pivoted in the first rotational direction (R1) .
Since the operation of the driving unit 4 actuates the operation of the steering unit 3 through the transmitting unit 5, water flowing from the water outlet 25 is guided by the fluid-guiding tube 31 to turn the board body 21 in the rotational directions (R1, R2) .
It is noted that the transmitting unit 5 may be a wireless signal control system that includes a sensor.
The sensor detects the rotational angle and rotational direction of the linking member 42. The fluid-guiding tube 31 may be mounted with a receiver to receive a signal transmitted from the sensor of the transmitting unit 5 for controlling rotation of the fluid-guiding tube 31.
To sum up, since the drive arm 44 is untwistable and is retained by the base seat 41, the drive arm 44 can spin about its own axis without significant swinging so that the operator can easily maintain balance when controlling the moving direction of the surfboard 2. In addition, due to the flexibility of the drive arm 44, the surfboard can withstand relative displacements between the drive arm 44 and the board body 21 when, e.g., the operator moves on the surfboard 2 due to waves better than the rigid driving arm 144 (see Fig. 1) of the prior art, thereby enhancing operability by the operator.
Referring to Figs. 4 and 5, the drive arm 44 of the driving unit 4 has a flexible tubular wall 441 and a plurality of angularly spaced apart steel cables 442 that extend along and that are embedded in the tubular wall 441. In this embodiment, the tubular wall 441 is made of rubber. Each of the steel cables 442 is composed of a plurality of steel strands, or may have only one steel strand. The drive arm 44 has a torque tolerance along the longitudinal axis thereof within 5 degrees, which makes the drive arm 44 substantially untwistable.
The handle 46 of the driving unit 4 is ring-shaped, and has a holding section 461 substantially perpendicular to the longitudinal axis of the drive arm 44 at the access end of the drive arm 44.
Referring back to Figs. 2 to 4, the transmitting unit 5 interconnects the linking member 42 and the steering unit 3 such that the rotation of the linking member 42 about the driving axis (D) drives pivot operation of the steering unit 3 via the transmitting unit 5. The transmitting unit 5 includes a sleeve 51, a cable 52, a driving steering lever 53, and a driven steering lever 54. The sleeve 51 is adapted to be secured to the board body 21 and has opposite ends adjacent respectively to the driving unit 4 and the steering unit 3. The cable 52 extends through the sleeve 51 and has opposite ends.
The driving steering lever 53 is connected to one of the opposite ends of the cable 52, and the driven steering lever 54 is connected to the other one of the opposite ends of the cable 52. The driven steering lever 54 has a distal end that is opposite to said other one of the opposite ends of the cable 52 and that is connected pivotally to the steering unit 3. The driving steering lever 53 has a distal end that is opposite to said one of the opposite ends of the cable 52 and that is connected pivotally to the linking member 42.
Referring to Figs. 3, 6 and 7, the steering unit 3 includes a fluid-guiding tube 31 that is connected pivotally to the power unit 22, that is adapted to be disposed in fluid communication with the water outlet 25 of the surfboard 2, and that is connected pivotally to the distal end of the driven steering lever 54 so that the rotation of the linking member 42 about the driving axis (D) in a rotational direction drives the fluid-guiding tube 31 to rotate in an opposite rotational direction.
To change the moving direction of the surfboard 2, as shown in Fig. 6, an operator standing on the board body 21 holds the holding section 461 of the handle 46 and rotates the drive arm 44, so that the linking member 42 spins in a first rotational direction (R1).
Consequently, the driving steering lever 53 is moved and moves move the driven steering lever 54 via the cable 52, thereby driving the fluid-guiding tube 31 to pivot in a second rotational direction (R2) opposite to the first rotational direction (R1). On the contrary, referring to Fig. 7, when the drive arm 44 is rotated to drive the rotation of the linking member 42 in the second rotational direction (R2) , the fluid-guiding tube 31 is pivoted in the first rotational direction (R1) .
Since the operation of the driving unit 4 actuates the operation of the steering unit 3 through the transmitting unit 5, water flowing from the water outlet 25 is guided by the fluid-guiding tube 31 to turn the board body 21 in the rotational directions (R1, R2) .
It is noted that the transmitting unit 5 may be a wireless signal control system that includes a sensor.
The sensor detects the rotational angle and rotational direction of the linking member 42. The fluid-guiding tube 31 may be mounted with a receiver to receive a signal transmitted from the sensor of the transmitting unit 5 for controlling rotation of the fluid-guiding tube 31.
To sum up, since the drive arm 44 is untwistable and is retained by the base seat 41, the drive arm 44 can spin about its own axis without significant swinging so that the operator can easily maintain balance when controlling the moving direction of the surfboard 2. In addition, due to the flexibility of the drive arm 44, the surfboard can withstand relative displacements between the drive arm 44 and the board body 21 when, e.g., the operator moves on the surfboard 2 due to waves better than the rigid driving arm 144 (see Fig. 1) of the prior art, thereby enhancing operability by the operator.
While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretations and equivalent arrangements.
