As shown in Figures 1 and 2, the steering apparatus according to the embodiment of the present invention is installed on the long axis 30 of the screw motor driver 20 for generating a propulsion force on the motor board, the screw motor driver 20 The mounting bracket 20 is provided for mounting on the motor board.

Reference numeral 40 is a shaft handle pivot 40 fixed to the upper end of the long shaft 30 by a fastening bolt 32, the pivot shaft 50 is pivoted to the shaft handle pivot 40 is pivotally connected, The pivot shaft 50 is connected to the upper and lower pair of control box covers 70 and 72 in which a switch circuit box 60 for switching control of the screw driver 20 is installed. Therefore, the control box covers 70 and 72 are tiltable up and down about the pivot shaft 50.

The control box cover 70 and the shaft handle pivot (70) so that the control box cover (70, 72) can be fixed and released at a desired position while tilting rotation about the pivot axis (50) in the shaft handle pivot (40) ( 40) is provided with a tilting fixing means.

The tilting fixing means forms a pair of stops 42 in an arc shape divided in opposition to an upper portion of the shaft handle pivot 40 about the pivot axis 50 in FIGS. A plurality of engaging grooves 42a and stepped 42b are provided in the 42.

At this time, the locking groove 42a can be tilted in a range such that the control box covers 70 and 72 maintain a horizontal position and rotate up to about 30 degrees upward and up to about 25 degrees downward. It is arrange | positioned suitably to the stop part 42 so that it may become.

That is, in the present embodiment, a plurality of locking grooves 42a are disposed at an appropriate position so that the tilting positions of the control box covers 70 and 72 can be taken in a horizontal position, an upper lifted two-seat position, and a lowered one-seat position. .

And the control box cover (70, 72) to be fixed in the corresponding tilting position in the upper control box cover 70, the elastic stop member 100 which is engaged with the engaging groove (42a) of the stop portion 42 by an elastic force ) Is installed.

An elastic stop member mounting portion 73 is formed on the inner side of the upper control box cover 70 and protrudes in a substantially rectangular frame, and both ends of the elastic stop member 100 are forced on the inner wall of the elastic stop member mounting portion 73. It is inserted into and elastically mounted.

In the present embodiment, the elastic stop member 100 is made of a spring steel plate to be convex substantially downward, and at its central portion is formed a protrusion 102 which is secured to the locking groove 42a.

Accordingly, when the control box covers 70 and 72 are tilted by the handle knob 92 to be described later, the protrusion 102 of the elastic stop member 100 is fixed to the locking groove 42a at a corresponding position.

One end of the switch actuating rod 80 is connected to the rotary actuating part of the switch circuit box 60 with a screw, and the other end of the switch actuating rod 80 is a predetermined section from one end of the control box cover 70, 72. It extends long.

The switch operating rod 80 is connected to the handle shaft 91 is provided with a handle handle 92. At this time, the handle shaft 91 and the switch operation rod 80 is coupled to the handle shaft 91 is coupled to the expansion or contraction movement in a linear direction from the switch operation rod 80. The handle shaft 91 is rotatably mounted to the control box covers 70 and 72.

Between the handle shaft 91 and the switch operating rod 80, the control box cover (70, 72) to allow the sliding movement and at the same time expand or contract to the desired position and then fixed the handle shaft (91) Extension fastening means are included.

2, 4, and 5, the expansion fixing means alternately forms the lower stepped grooves 91a and the deep stepped grooves 91b extending in the longitudinal direction on the inner surface of the handle shaft 91, and the switch operation. A tube 201 is provided in a substantially central portion of the rod 80, and a steel ball 203 supported by the elastic spring 202 is placed on the tube 201, so that the steel ball 203 is formed of the handle shaft 91. It is configured to be resiliently pushed in the deep shot groove (91b).

At this time, the low stepped groove 91a is for inducing the steel ball 203 to easily enter into the deep stepped groove 91b before and after adjacent from the low stepped groove 91a.

The operating state of this embodiment configured as described above will be described.

1 and 2, when the handle knob 92 is placed in a horizontal state, the protrusion 102 of the elastic stop member 100 installed in the upper control box 70 is the shaft handle pivot 40 as shown in FIG. It is elastically locked to the locking step (42a) formed in the center of the stop (42).

In this state, while holding the handle knob 92 and tilting upward, the control box covers 70 and 72 are rotated counterclockwise in FIG. 2 about the pivot shaft 50 integrally with the handle shaft 91. At this time, the protruding portion 102 of the elastic stop member 100 passes over the stepped 42b of the shaft handle pivot 40 and is stuck to the next locking groove 42a to maintain the tilting position of the first or second stage upward.

In addition, when the tilting operation is performed so that the handle knob 92 is completely lowered downward, the handle knob is positioned downward in one step by the above action.

On the other hand, the present invention can be extended (extending) or reduced (reduction) with the handle handle while at the same time the tilting operation.

That is, when the handle handle 92 is to be extended or reduced, when the handle handle 92 is pulled outward or pushed inward, the handle shaft 91 is pulled out or enters from the switch operating rod 80, and at this time, the steel ball 203 Relatively ride the engaging grooves (91a, 91b) formed on the inner surface of the handle shaft 90 as shown in FIG.

When the handle handle 92 is extended at an appropriate position, the steel ball 90 is fixed to the corresponding locking groove (91a or 91b) by the force of the elastic spring (202).

As such, the steering apparatus of the present invention has both an extended function and a tilting function for the operator's steering wheel operation convenience, thereby improving steering capability and convenience.

As described above, according to the present invention, the steering wheel for steering the screw drive unit can perform both steering and tilting from the long axis, so that it can take a steering posture suitable for the operator's operating posture. Therefore, the steering ability is improved, and the convenience of operation is further enhanced.
