Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a device for preventing forgetting to return the side stand of a motorcycle.

[Prior art]

A side stand installed on a motorcycle is placed in an upright position to support the motorcycle so that it does not fall over when parked, and is laid down to a substantially horizontal position on the side of the motorcycle when traveling so as not to interfere with traveling. However, when driving, the vehicle often forgets to return the side stand to its folded position. Therefore, in order to prevent forgetting to return the side stand, a switch is installed that operates in conjunction with raising or lowering the side stand.
It has been proposed to prevent the engine from starting as long as the side stand is in the upright position, or to issue an alarm.

However, this device has a problem in that when the switch is operated, an impact force is applied to the switch operator, which tends to damage the switch operator and the switch body. Furthermore, while the vehicle is running, the switch operator and the switch body may be similarly damaged by stones or the like thrown up from the road surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The following describes embodiments of the present invention shown in the drawings.

FIG. 1 is a side view of a motorcycle equipped with a side stand forgetting prevention device of the present invention.

In FIG. 1, 1 is a front wheel, 2 is a rear wheel, 3 is an engine, 4 is a down tube constituting the body frame, 5 is a side stand, 6 is a handle, and 7 is a seat. The side stand 5 is provided at a lower position of the down tube 4. This side stand 5 is placed in a reclined position where it is stored horizontally as shown in the figure when driving, but when parked it is placed in an upright position protruding diagonally outward and downward to support the vehicle body.

FIGS. 2A, B, and C show a device for preventing forgetting to return the side stand according to the present invention.

As shown in the figure, a side stand bracket 8 that pivotally supports the side stand 5 and a switch bracket 9 that fixes a switch 13 for detecting that the side stand 5 has been forgotten to return are welded and fixed on the frame of the same down tube 4, respectively. There is.

For such fixing, the side stand bracket 8 has its lower end protruding diagonally outward to form a slope. A pivot bolt 10 is fixed to the slope, and an end portion of the side stand 5 is rotatably supported on the pivot bolt 10.
Numeral 11 is a nut screwed onto the support bolt 10.
Further, a projection 8a is provided above the pivot bolt 10 and the nut 11, and a return spring 12 is stretched between the projection 8a and the hook 5a in the middle of the main body arm of the side stand 5. There is.

On the other hand, a switch 13 is fixed to the switch bracket 9, and is positioned near the upper part of the arm of the main body of the side stand 5 when it is in the collapsed position. This fixation is achieved by bringing a bracket 13a integral with the switch into contact with the switch bracket 9 and tightening it with a screw 14. The switch 13 is provided with an operator 15 for operation. This operator 15 has its tip end connected to the projection 8.
It is inserted into a hole drilled in a through a guide 16 made of resin and is held slidably. This switch 13 is connected to a suitable alarm device or starting motor via a cord 13b, and turns ON or OFF to issue an alarm when the side stand 5 is in the upright position, or prevents the starting motor from turning. There is.

An operating member 5b is integrally provided on the pivot point side of the side stand 5. This operating member 5b
When the side stand 5 is returned and raised to the position shown by the chain line against the elastic force of the spring 12, they rotate together, and the tip of the operator 15 is pushed in to operate the switch 13. On the other hand, side stand 5
When returning to the laid down position shown by the solid line, press spring 12.
It is forcefully returned by the elastic force in the direction of contraction. After the side stand 5 returns to the reclining position, the reclining position is maintained by the return spring 12. In this return operation, the operating member 5b is
5, the operator 15 returns to its original position and the operating state of the switch 13 is released.

As described above, when the side stand 5 is operated to stand up, the side stand 5 is operated against the tensile elastic force of the return spring 12, so the actuating member 5b does not apply an impact force to the operator 15. It acts very slowly. on the other hand,
When the side stand 5 is in the folded position, the actuating member 5b separates from the operator 15 and the operator 15 is released, so vibrations of the side stand 5 are transmitted to the switch 13 via the operator 15 while driving. There is no risk of switch failure. Further, since the switch 13 is of simple operation, being pressed when the side stand 5 is in the upright position and released when it is in the lying position, the switch structure can be made simple and simple.

Furthermore, the end of the operator 15 is placed above the slope of the side stand bracket 8, and at the same time,
Since it is located near the upper part of the shaft support bolt 10,
Even if stones or the like jump up from below, the obliquely projecting side stand bracket 8 and the convexly projecting shaft support bolt 10 reliably protect the operator, and the end of the operator will not be damaged. Such a protective action is also performed by the return spring 12, the main body arm of the side stand 5, and the like.

Further, the switch 13 is fixed on the down tube 4 of the same frame as the frame to which the side stand bracket 8 is fixed. Therefore, the side stand 5 and the switch 13 can be attached with high precision without causing a large error in the relative positional relationship. Therefore, in the past, the stroke amount of the switch was set longer in anticipation of installation errors, which resulted in an increase in the size of the switch 13, but this can be eliminated and the switch 13 can be made more compact.

〔Effect of the invention〕

As described above, the device for preventing forgetting to return the side stand of a motorcycle according to the present invention fixes the side stand bracket to the frame with the lower end protruding diagonally outward to form a slope, and the pivot bolt is placed on the slope of the side stand bracket. fixed,
The side stand is rotatably supported on this pivot bolt between an upright position where it protrudes diagonally downward against the spring and a laid down position where it is biased by the spring and stored horizontally. A switch for detecting the state is arranged near the upper part of the main body arm of the side stand when it is in the collapsed position, and the operator of this switch is arranged above the slope and near the upper part of the pivot bolt. The side stand is pressed by an actuating member that is linked to the movement of the side stand to the upright position, and the pressing operation is maintained.

Therefore, since the operating member of the switch is operated by the actuating member when the switch is raised when no impact force is applied, rather than when the switch is lowered when the elastic impact force of the spring is applied, the switch is not damaged by the elastic force. . On the other hand, when the side stand is in the reclined position, the control is released, so the vibration of the side stand does not affect the switch via the control while the vehicle is running, which can lead to switch failure due to vibration of the side stand. Never. Furthermore, since the switch is of simple operation, being pressed when the side stand is in the upright position and released when the side stand is in the down position, the switch structure can be simplified.

In addition, the switch controls are protected from flying stones by the diagonally protruding side stand bracket and convexly protruding pivot bolt.
It also becomes less susceptible to damage from these flying stones. Furthermore, since the switch is located above and near the main body arm of the side stand in the inverted position when the vehicle is running, it can be protected from flying stones by the main body arm.
