Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a tilting support device used during maintenance of a motorcycle.

(Prior Art) Due to the structure of a motorcycle, functional parts are exposed, and from the viewpoint of safety, the functional parts are arranged as low as possible. For this reason, when servicing a motorcycle, workers have to work in a cramped position with the motorcycle in an upright position, and there is a risk of damage to the motorcycle or injury due to falls. A problem arises.

(Purpose) The present invention was made in view of the above circumstances, and its purpose is to allow the worker to work safely in a comfortable posture by tilting and holding the vehicle body. Moreover, it is an object of the present invention to provide a tilting device for motorcycle maintenance that can be easily moved as needed.

(Structure) Therefore, details of the present invention will be described below based on illustrated embodiments.

Figures 1 and 2 show an embodiment of the present invention, in which a base body 1 having a planar trapezoidal shape with a grip portion 2 for movement on the top side is provided with sector gears 4, 4 provided at the tip. A pair of left and right frames 3, 3 connected by meshing with each other are rotatably supported on the bottom side, and a parallel link mechanism is provided on the outside of each frame 3, 3. One end of the auxiliary rods 5, 5 of the same length constituting the frame 3, 5 is rotatably supported, and the cross section L is pivotally supported at each free end of the frame 3, 3 and the auxiliary rod 5, 5.
A pair of wheel supports 6, 6 forming a letter shape are configured to be able to open and close parallel to the bottom side of the base body 1 and symmetrically with respect to the central axis. Further, an arm bracket 7 is fixedly installed on the upper surface of the base body 1 described above.
A telescopic vehicle body support arm 9 having a pad 8 supporting the side surface of the vehicle body is pivotally supported so as to be able to extend inwardly. In the figure, reference numeral 10 indicates a pad height adjustment pin, and reference numeral 11 indicates a moving caster fixed to the outer end of the wheel receivers 6, 6.

In the device configured in this way, when one or both of the frames 3, 3 is expanded outward in order to adjust the distance between the pair of wheel receivers 6, 6 to the wheel base of the two-wheeled vehicle, the sector gears 4, 4 Both frames 3, 3, which are meshed together and become one body, expand symmetrically from the center, and along with this, the wheel supports 6, 6 attached to the tips of the frames 3, 3, the base body 1, the frame 3, the auxiliary rod 5, and the wheel support. The parallel link mechanism constituted by 6 expands on the same axis while maintaining a parallel state to the bottom side of the base body 1. Next, the two-wheeled vehicle is placed on the pair of wheel receivers 6, 6 that have been expanded in this way,
When the vehicle body support frame 9 whose length has been adjusted in advance is tilted and the vehicle body W is laid down on top of it, the vehicle body W is stabilized by the L-shaped wheel supports 6, 6 and the vehicle body support arm 9. Supported by leaning into the posture.

Note that if the tilting device is raised in this state until the vehicle body is nearly vertical, the casters 11 provided at the outer ends of the wheel receivers will touch the ground, so it can be easily moved to the desired position using the gripping portion 2. It is possible,
Further, when not in use or when being transported, the apparatus can be moved or stored in a compact manner by folding both arms 3, 3 and laying down the vehicle body support arm 9 thereon.

The embodiment shown in FIG.
One end of each is pivoted to one of the frames 3, 3, and the other end is inserted into a long hole 23, 23 drilled in the other frame 3, 3, respectively, to connect both frames 3, 3. This link mechanism also allows both arms to be opened and closed symmetrically.

(Effects) As described above, according to the present invention, a pair of wheel receivers are pivotally supported at the other ends of two sets of two rods that are pivotally supported on a base plate, and a side surface of the vehicle body that can be raised and lowered on the base board. Since the support member is pivoted, the device can be adapted for maintenance of various types of two-wheeled vehicles by opening and closing the wheel receivers in the same line.
The pair of wheel supports and body side support members that maintain the same orientation allow the motorcycle to be tilted and supported in a stable state, allowing workers to carry out maintenance work with a comfortable posture and wide field of view. In addition, the left or right side of the crankcase can be removed without draining the engine oil, greatly improving work efficiency. Moreover, since these two sets of rods are connected via a mechanism that opens and closes symmetrically, not only can the device be given a stable vehicle body support posture, but the device can be easily folded when not in use. It can be folded and stored.
