Description

  The present invention relates to a front wheel holding device and a tipping prevention device that prevent the motorized motorcycle from falling over during parking.

In recent years, enforcement against parking violations has been strengthened, and the number of cases where parking violations are applied to motorized motorcycles is increasing. On the other hand, in order to strengthen the enforcement of parking violations, it is necessary to have a parking lot for powered motorcycles. However, in areas where land prices are soaring, such as in the city center, new parking for powered motorcycles is required. It is not easy to secure a parking lot.
Therefore, in order to be able to effectively use the space that is often installed in the city center etc., it is possible to utilize the mechanical multistory parking lot that is often installed in the city center etc. as a parking lot for powered motorcycles. Conceivable.

However, powered motorcycles are less stable when parked than four-wheeled vehicles, and if they are parked as they are in a mechanical multistory parking lot, they will fall down due to impacts caused by an emergency stop of the parking device or vibration due to earthquakes, etc. There is a danger to do. For this reason, various types of two-wheeled vehicle stands for stably parking a powered two-wheeled vehicle have been proposed (Patent Document 1, Patent Document 2).

In the following description, it is assumed that the front wheel fixing portion is configured by the front wheel fixing portion 10B. Hereinafter, a mechanism in which the front wheel holding device 3 holds the front wheels of the two-wheeled vehicle will be described.

FIG. 11 is a front view of the front wheel holding device 3, FIG. 12 is a plan view of the front wheel holding device 3, and FIG. 13 is a schematic operation diagram of the front wheel holding device 3.
With reference to the above-mentioned figures and these figures, the mechanism for holding the front wheels of the two-wheeled vehicle in the front wheel holding device 3 is mainly composed of two mechanisms.
The first mechanism includes a slide restricting bar 38, 38 extending horizontally on both sides in the width direction, and the rear wheel moving part base 11 for contacting the slide restricting bar 38, 38. This is a mechanism in which guide guides 39, 39 standing on the end side are combined. In the slide regulating rods 38, 38, the bearings 38b, 38b abut against the guide guides 39, 39.

The second mechanism includes a floating restriction rod 40 extending in the width direction on the side portion 33 of the lower holding portion 19 and a front wheel moving portion base for abutting the floating restriction rod 40 on its lower surface. 11 is a mechanism in which a horizontal guide plate 23a fixed to the motor 11 is combined. In the floating regulating rod 40, the bearing 40b comes into contact with the lower surface of the horizontal guide plate 23a.
These mechanisms are set in size (length, etc.) and mounting position so as to exhibit the following functions. As a first function, when the lower holding portion 19 swings forward in accordance with the forward movement of the two-wheeled vehicle (front wheel), until the floating restriction rod 40 is positioned below the horizontal guide plate 23a. The slide restricting rods 38 and 38 (bearings 38b and 38b) are in contact with the rear sides of the guide guides 39 and 39, respectively, to prevent the lower holding portion 19 from moving forward.

As a second function, when the lower holding portion 19 swings forward and the slide restricting bar 38 gets over the guide guide 39 and the lower holding portion 19 is allowed to move forward, the floating restricting rod 40 is moved. Is a function that prevents the lower holding portion 19 from swinging backward when entering the lower side of the horizontal guide plate 23a and moving the lower holding portion 19 forward.
Next, a procedure for fixing the two-wheeled vehicle to the fall prevention device 1 will be described.
First, the front wheel moving part 9 is moved to the rear moving end, and the lower holding part 19 is swung to the rear rocking end. At this time, as shown in FIG. 13, the slide restricting bars 38 are positioned on the rear side of the corresponding guide guides 39, 39. In this state (A1), the front wheel moving portion 9 is prevented from moving forward by the slide restricting rods 38, 38 being locked to the guide guides 39, 39. Further, the clamping operation of the toggle clamp 24 of the pedestal fixing portion 18 is released, that is, the meshing of the teeth of the small rack portion 25 and the teeth of the rack 15 is released so that the pedestal portion 17 can move back and forth. Keep it. Further, the clamping operation of the toggle clamp 47 in the front pressing portion 44B of the front wheel fixing portion 10B is released.

  When the front wheel T of the two-wheeled vehicle is inserted into the rear locking portion 31 of the lower holding portion 19, the front wheel T comes into contact with the wheel support portion 32. The front wheel moving portion 9 is held downward by the front wheel T pushing the wheel support portion 32 because the bearings 38b, 38b of the slide regulating rods 38, 38 are locked to the guide guides 39, 39 to restrict the forward movement. The part 19 tries to swing forward. At this time, the slide regulating rods 38, 38 have their bearings 38b, 38b abutting on the rear side of the guide guides 39, 39 and rolling to move upward, so that the lower holding portion 19 swings forward. It is done smoothly.

When the slide restricting rods 38 and 38 reach the upper ends of the guide guides 39 and 39 with the lower holding portion 19 positioned at the swinging end on the front side (A2), the front wheel moving unit 9 is released from the movement restriction and moved forward. Start moving to. At this time, the floating regulating rod 40 (the bearing 40b thereof) is positioned below the lower surface of the horizontal guide plate 23a. In other words, the floating regulating rod 40 (the bearing 40b thereof) is integrated with the lower holding portion 19 so that the lower holding portion 19 is positioned below the lower surface of the horizontal guide plate 23a when the lower holding portion 19 reaches the front swing end. Has been.
The horizontal guide plate 23a does not hinder the movement of the lower holding portion 19 swinging to the swing end on the front side when the slide restricting rods 38, 38 get over the guide guides 39, 39, that is, the floating restricting rod 40 ( The position of the rear end is set so that the bearing 40b) can move below the lower surface of the horizontal guide plate 23a without being obstructed by the rear end of the horizontal guide plate 23a. Further, the horizontal guide plate 23a covers the upper portion of the floating restricting rod 40 by a slight forward movement of the two-wheeler thereafter, and causes the lower restricting portion 19 to swing backward so that the floating restricting rod 40 abuts. The position of the rear end is set so as to prevent it by locking.

Now, when the two-wheeled vehicle is subsequently moved forward, the slide restricting rods 38, 38 get over the guide guides 39, 39, and the lower holding portion 19 swings to the front swing end. During the forward movement of the two-wheeled vehicle, the floating regulating rod 40 enters under the horizontal guide plate 23a, and the bearing 40b enters the lower surface of the horizontal guide plate 23a.
Thereafter, when the two-wheeled vehicle is moved forward, the front wheel moving unit 9 causes the front end of the front wheel T to be forwardly locked to the front wheel fixing unit 10B in a state where the floating regulating rod 40 is inserted below the horizontal guide plate 23a. It moves forward until it comes into contact with the portion 43B (A3).

When the front wheel comes into contact with the front locking portion 43B of the front wheel fixing portion 10B and the movement of the front wheel moving portion 9 is stopped, the toggle clamp 24 of the base fixing portion 18 is clamped to restrict the movement of the front wheel moving portion 9. . At this time, since the floating restriction rod 40 is in contact with the lower surface of the horizontal guide plate 23a, the lower holding portion 19 is prevented from swinging (floating).
In the front wheel holding device 3, when the lower holding portion 19 is swinging, the lower holding portion 19 is restricted from moving forward or backward, and the lower holding portion 19 is moved forward or backward. In this case, the swinging of the lower holding part 19 is restricted exclusively (selectively) during the swinging and moving operation of the lower holding part 19.

Next, the handle 52B of the front pressing portion 44B is pushed down (in the direction indicated by the arrow X in FIG. 13), and the toggle clamp 47 is brought into a clamped state. At this time, the action end of the toggle clamp 47 moves rearward and pushes the upper end of the front locking portion 43B toward the front wheel to rotate the front locking portion 43B around the swing shaft 76B. The rotated front locking portion 43B bites the upper end of the front wheel into the front wheel of the two-wheeled vehicle and pushes the front wheel back toward the rear locking portion 31. The front wheel T is held by the front wheel holding device 3.
In the front wheel holding device 3, when the rear locking portion 31 and the front locking portion 43 </ b> B hold the front wheel T, the floating regulating rod 40 (the bearing 40 b thereof) always enters the lower side of the horizontal guide plate 23. Therefore, the swing of the lower holding portion 19 that holds the front wheel T of the two-wheeled vehicle is limited, and the front wheel holding device 3 continues to hold the front wheel T firmly even when subjected to external force such as vibration caused by an earthquake, for example. Can do.

Further, the bottom 45B of the front locking portion 43B after the rotation is in a state of facing (approaching in parallel with) the surface 36 that locks the wheel in the rear locking portion 31 than before the rotation. Therefore, the force with which the front locking part 43B and the rear locking part 31 that oppose each other acts effectively on the front wheel, and the front wheel is firmly held between the front locking part 43B and the rear locking part 31. The independence of motorcycles is stabilized.
In order to prevent the clamp state of the toggle clamp 24 of the base fixing portion 18 and the toggle clamp 47 of the front pressing portion 44 from being released by vibration or the like, the respective lock rods are passed through the two holes of the rod support portion. The clamp is prevented from being released due to the rotation of the handle 28 or the like.

With the above operation, the two-wheeled vehicle is fixed to the fall prevention device 1 by holding the front wheel.
Subsequently, the handle grip of the motorcycle is accommodated in the cylinders 66 and 66 of the grip holding portions 60 and 60. At this time, if the distance between the grip holding portions 60 and 60 is long or short enough to not accommodate the handle grip, the pressing members 63 and 63 are rotated so that the distance between the grip holding portions 60 and 60 is set appropriately. Adjust. After the handle grips are accommodated in the cylinders 66 and 66, the high nuts 67 and 67 at both ends of the grip holding portion adjusting portion 61 are moved so that the pressing members 63 and 63 do not rotate outward, thereby The grip is prevented from coming out of the cylinders 66 and 66.

In addition, since the grip holding parts 60 and 60 can rotate two degrees of freedom with the two rotation axes orthogonal to each other, the handle grips can be easily accommodated in the cylinders 66 and 66.
The cylinder 66 of the grip holding part 60 can have other forms. For example, the cylinder is divided into two on the plane including the axis, and the divided ends are connected by a hinge so that the cylinder can be opened and closed. In this form, the fastener which can maintain the state faced | matched is provided in the edge of the side to which the hinge is not attached. By doing in this way, it can respond also to the handlebar grip to which the handle guard was attached. As the grip holding portion 60, any shape can be used as long as it does not come off the handle grip when the handle grip is pressed.

Now, the sling belt 68 of the sheet pressing portion 55 is loosened to such an extent that the sheet pressing portion 55 is rotatable in a state where the handle grip is housed in the cylinders 66 and 66 of the grip holding portions 60 and 60.
The rear end of the weight arm 56 is pulled down while keeping the front end of the seat pressing portion 55 at an appropriate position on the seat of the motorcycle. Then, the pressing members 63, 63 press the handle to contract the front shock absorber (front fork), and the sling belt 68 presses the seat to contract the rear shock absorber (rear fork). In this state, the hook of the wire 71 of the rear wheel guiding portion 70 is coupled to the ring 69 at the rear end of the weight arm 56. The length of the wire 71 is adjusted in advance so that the front and rear shock absorbers can be maintained in a contracted state.

The appropriate position of the front end of the sheet pressing portion 55 is a position where the sheet pressing portion 55 (sling belt 68) presses the seat directly below or slightly forward when the overturn prevention device 1 fixes the motorcycle. .
The overturn prevention device 1 is configured such that when the two-wheeled vehicle is fixed, the pressing members 63 and 63 are inclined in the same direction as the caster angle of the two-wheeled vehicle with respect to the vertical direction. That is, the pressing members 63 and 63 press the front wheel in the direction of the front locking portion 43 of the front wheel fixing portion 10. As a result, the front wheel is more firmly held by the front locking portion 43. Furthermore, since the sheet pressing portion 55 presses the sheet from directly above, it is difficult to come off, and the state of holding the sheet is maintained even by vibration or the like.

In this manner, the overturn prevention device 1 can firmly hold the two-wheeled vehicle at the three positions of the front wheel, the handle, and the seat, and can stably prevent the overturn even when a large vibration such as an earthquake is applied. .
In the above-mentioned embodiment, the member which comprises the fall prevention apparatus 1 and its front wheel holding | maintenance apparatus 3 was specified and demonstrated. However, the member to be used is not limited to, for example, a square pipe, a square steel, and a circular pipe, and other usable members can be used. The function of can be demonstrated.

The front wheel holding device 3 may not be fixed to the frame 2 but may be fixed to a mounting surface on which the frame 2 is fixed in a specific positional relationship with the handle holding device 4.
In addition, each structure or overall structure, shape, dimension, number, material, and the like of the fall prevention device 1 and the fall prevention device 1 can be appropriately changed in accordance with the spirit of the present invention.
