  In the case of the parking device according to the conventional example 1 or 2, the front wheel side of the bicycle must be lifted to some extent in either case of parking or stopping parking. If there is no load on the front wing on the front wheel side of the bicycle, it is considered that it is not so much. However, for example, in the case of a housewife who went shopping at a supermarket or the like, various purchased items may be loaded on the front wing, and in some cases, the luggage may be loaded on the loading platform on the rear wheel side. Therefore, since the whole bicycle as well as the front wheel side of the bicycle becomes heavy, it is difficult to stop parking.

  Further, in the case of the bicycle parking apparatus according to the conventional example 1, it is not necessary to stand the bicycle vertically by using the rear stand when parking the bicycle. That is, it is convenient because it is not necessary to lift the rear wheel side of the bicycle. However, in the case of the bicycle parking apparatus according to the second conventional example, it is necessary to use the rear stand, which is troublesome. In addition, when the bicycle of one stand that tilts and stands up is parked, There are bicycles (for example, sports cars) that cannot be parked depending on the relationship of the inclination of the vehicle and the width of the front wheels.

  Accordingly, it is an object of the present invention to avoid the need to lift the front wheel, to use the rear stand of the two-wheeled vehicle, and to determine the width of the front wheel. It is to provide a bicycle parking device that makes it possible to park in a vertically upright and fixed state regardless of whether or not.

  The present invention has been made in view of the above circumstances, and therefore, in order to solve the problem, the means employed by the bicycle parking apparatus according to claim 1 of the present invention is installed in a bicycle parking area of a motorcycle, A bicycle parking device that holds a motorcycle in a vertical and upright state by fixing a front wheel, and stands on a downwardly inclined surface that supports the tire rolling surface of the front wheel from below, and on the lowest position side of the downwardly inclined surface A pair of arm support struts and a pair of arm support struts are pivotally supported via a horizontal support shaft, and the space between the shaft support portions is set at an interval where the front wheel support shaft of the front wheel can enter.

  Further, according to the bicycle parking apparatus according to claims 1 to 4 of the present invention, the distance between the shaft support portions of the front wheel fixing arm is set so that the front wheel support shaft of the front wheel of the two-wheeled vehicle can enter. A motorcycle can be parked regardless of the situation. Furthermore, simply by reversing the two-wheeled vehicle on the downwardly inclined surface, the pressing state between one place on the tire rolling surface of the front wheel by the downwardly inclined surface and two places on the tire rolling surface of the front wheel by the front wheel fixing arm is released. Therefore, when stopping parking, there is no need to lift the front wheel side of the motorcycle.

  According to the third aspect of the present invention, the front wheel fixing arm includes an upper arm portion having an upper pressing arc portion that presses the tire rolling surface above the front wheel support shaft of the front wheel, and a front wheel support for the front wheel. And a lower arm portion having a lower pressing arc portion that presses a tire rolling surface below the shaft. The upper pressing arc portion and the lower pressing arc portion are positioned in the forward direction of the motorcycle relative to the front wheel support shaft, and the centers of the radii of curvature of the upper pressing arc portion and the lower pressing arc portion are the front wheel fixing arms. It is located on the center line passing through the center in the width direction. Accordingly, the front wheel of the two-wheeled vehicle is held in a vertical and upright state by the front wheel fixing arm at a substantially central position in the width direction of the front wheel fixing arm.

Therefore, the lower arm part of the front wheel fixing arm is always located on the lower side, and the upper arm part is always located on the upper side, so that the front wheel fixing arm is in the dead point position or reversed. There is no problem, and the two-wheeled vehicle is reliably rotated by the contact of the front wheel.

  Hereinafter, the bicycle parking apparatus according to the first embodiment of the present invention will be described with reference to FIGS. 1 and 2 of the accompanying drawings, taking as an example a case where the two-wheeled vehicle is a bicycle. FIG. 1 is a side view of a bicycle parking apparatus according to Embodiment 1 of the present invention, and FIG. 2 is a front view of the bicycle parking apparatus according to Embodiment 1 of the present invention.

Reference numeral 1 shown in FIG. 1 is a bicycle parking apparatus according to Embodiment 1 of the present invention. The bicycle parking apparatus 1 includes a base plate 2 installed in a bicycle parking area 9 by mechanical fixing means such as an anchor bolt (not shown). On the upper surface of the base plate, a pair of arm support struts 3 made of a flat steel material are erected at a predetermined interval, and between the pair of arm support struts 3, a front wheel having a configuration described later is provided. The fixed arm 4 is pivotally supported so as to be reversibly rotatable. As shown in FIG. 1, the side surface shape of the front wheel fixing arm 4 is formed into a trapezoidal shape (sideways).
More specifically, the front wheel fixing arm 4 is composed of a straight portion at the center and end straight portions bent in opposite directions at both ends of the straight portion. In the case of the bicycle parking device 1 according to the first embodiment, the pair of arm support columns 3 are made of a flat steel material, but the pair of arm support columns 3 are made of, for example, channel steel. Alternatively, it may be made of L-shaped steel.

  Further, as shown in FIG. 2, the front wheel fixing arm 4 has a straight central portion which is parallel to the front, and the straight upper portion and the lower straight portion of the parallel straight portion are on the front end side. The tops are gradually narrowed, and each of the tops is connected by an arc having a center of curvature radius on a center line passing through the center in the width direction of the front wheel fixing arm 4 in order to hold the front wheel of the bicycle at the center position in the width direction. Yes. Further, brackets 4a each having a shaft fitting hole are provided in each of the parallel straight portions of the center portion of the front wheel fixing arm 4, and the shaft fitting holes of the bracket 4a and the top portion of the arm support column 3 are provided. It is pivotally supported so as to be rotatable in forward and reverse directions by a support shaft 7 described later, which is common to a shaft fitting hole provided in the vicinity. The support shaft 7 has a nut-shaped head on one end, and is screwed with a screw to which the nut 7a is screwed on the other end. In addition, the space | interval of the straight part of the center part of the front wheel fixing arm 4 is set to the space | interval which the front-wheel support shaft 12 of the front wheel 11 of a bicycle can enter.

  The upper portion of the front wheel fixing arm 4 in the drawing relative to the front wheel support shaft 7 is an upper arm portion 5 that presses the tire rolling surface 11a above the front wheel support 12 of the front wheel 11 of the bicycle, The arc forming portion is the upper pressing arc portion 5a. On the other hand, the lower portion in the figure than the front wheel support shaft 7 is a lower arm portion 6 that presses the tire rolling surface 11a below the front wheel support shaft 12 of the front wheel 11 of the bicycle, and an arc at the tip thereof. The forming portion is a lower pressing arc portion 6a. Further, the radius of curvature of the arc of the upper pressing arc portion 5a and the lower pressing arc portion 6a located in the forward direction of the bicycle with respect to the front wheel support shaft 12 of the front wheel fixing arm 4 is the cross section of the existing normal bicycle tire. It is set larger than the radius of curvature. This is intended to reliably hold the front wheel 11 regardless of the diameter of the bicycle tire.

  In the bicycle parking device 1 according to the first embodiment, as described above, the arc portion is provided at the tip of the front wheel fixing arm 4. However, if the width of the front wheel fixing arm becomes narrower toward the tip, that is, if the opposite side in the vertical direction is formed in a rhombus shape, the oblique side surface of the tire can be pressed. In addition, even if the front wheel fixing arm has a straight tip, the oblique side of the tire can be pressed by this straight portion, so the upper pressing arc portion 5a and the lower pressing arc portion 6a as described above must be provided. It doesn't mean you have to. Moreover, a rubber tube can be armored on the upper pressing arc portion 5a and the lower pressing arc portion 6a. By adopting such a configuration, the frictional force is increased, so that the stability of the holding state of the front wheels can be improved, and the front tire tire can be prevented from being damaged.

Rod-shaped tip side stoppers 4c that come into contact with each other protrude. Due to the action of these stoppers 4b and 4c, the lower arm portion 5 of the front wheel fixing arm 4 is always located on the lower side and the upper arm portion 6 is always located on the upper side, so that the front wheel fixing arm 4 is located at the dead point. In addition, the bicycle does not turn in the opposite direction and is reliably rotated by the abutment of the front wheel 11 of the bicycle.

  Furthermore, the front end side of the front wheel guide plate 8 made of a striped steel plate having a configuration to be described later is connected to the base plate 2. The front wheel guide plate 8 is orthogonal to the base plate 2 and, as shown in FIG. 1, is formed with an upward inclined surface inclined upward with respect to the forward direction of the bicycle, and downward from the uppermost position. An inclined downward inclined surface 8a is formed, and the tire rolling surface 11a of the front wheel 11 in contact with the upper pressing arc portion 5a and the lower pressing arc portion 6a of the front wheel fixing arm 4 is supported by the downward inclined surface 8a. It is configured.

  Incidentally, in the case of the bicycle parking device 1 according to this embodiment 1, the height dimension from the upper surface of the bicycle parking area 9 to the uppermost position of the front wheel guide plate 8 is set to about 7 cm at most, and The slopes of the upward inclined surface and the downward inclined surface 8a are both high or about 2/5. Accordingly, the force required to move the bicycle on the front wheel guide plate 8 is very small. In the case where the front wheel guide plate 8 is made of a flat steel plate, it is preferable to attach an anti-slip to the upper surface in order to prevent slipping.

  In short, in the bicycle parking device 1 according to the first embodiment, the front wheel 11 of the bicycle being parked is caused to roll the tire on the rear side of the bicycle from the front wheel support shaft 12 by the downward inclined surface 8a of the front wheel guide plate 8. The front wheel 11 is vertically raised by pressing at one place on the surface 11a and two places on the front and rear tire rolling surfaces 11a of the front wheel support shaft 12 in front of the front wheel support shaft 12 by the front wheel fixing arm 4. It is comprised so that it may hold in a state. A plurality of sets of bicycle parking devices 1 having such a configuration are arranged in parallel. In the bicycle parking device 1 according to the first embodiment, as described above, the side surface shape of the front wheel fixing arm 4 is bent into a horizontal trapezoidal shape, but is not limited to a horizontal trapezoidal shape. For example, the front wheel fixing arm may be bent in a dogleg shape (mountain shape) or may be curved in an arc shape.

Hereinafter, how to park a bicycle in the bicycle parking apparatus 1 according to the first embodiment of the present invention will be described.
That is, according to the bicycle parking device 1 according to the first embodiment of the present invention, the front wheel 11 is simply moved forward with the front wheel 11 of the bicycle facing the front wheel fixing arm 4 of the bicycle parking device 1 and the front wheel guide plate 8 being advanced. The tire rolling surface 11a contacts the upper pressing arc portion 5a and the lower pressing arc portion 6a of the front wheel fixing arm 4. And three places of the tire rolling surface 11a of the front wheel 11 are pressed, and the bicycle is fixed in a vertical / standing state.

  More specifically, the front wheel 11 of the bicycle being parked is from the tire rolling surface 11a (behind the front wheel support shaft 7) on the downward inclined surface 8a of the front wheel guide plate 8 and the front wheel support shaft 7 by the front wheel fixing arm 4. Is also pressed in a total of three locations, two on the front and upper and lower tire rolling surfaces 11a of the front wheel support shaft 7. In such a parking state, the front wheel 11 is on the upper surface of the downward inclined surface 8a of the front wheel guide plate 8, and a component force in the forward direction acts on the forward direction based on the weight of the front portion of the bicycle. In addition, the three places on the tire rolling surface 11a of the front wheel 11 of the bicycle are more strongly pressed. Therefore, the front wheel 11 of the bicycle is more firmly fixed, and the bicycle is held in a vertical / stand-up state, so there is no need to use the rear stand of the bicycle.

  In the case of a bicycle having a small tire size (24-inch and 26-inch tires mounted), the lower arm portion 6 of the front wheel fixing arm 4 first comes into contact with the tire rolling surface 11a of the front wheel 11, so that the front wheel is fixed. The upper arm portion 5 of the arm 4 rotates to the bicycle side. Conversely, in the case of a bicycle with a large tire size (27-inch tire mounted), first, the upper arm portion 5 of the front wheel fixing arm 4 contacts the tire rolling surface 11a of the front wheel 11, so The side arm 6 rotates to the bicycle side. That is, regardless of the size of the tire, three places on the tire rolling surface 11a of the front wheel 11 of the bicycle are securely fixed.

  Further, since the distance between the straight portions of the central portion of the shaft support portion of the front wheel fixing arm 4 is set such that the front wheel support shaft 7 of the front wheel 11 of the bicycle can enter, regardless of the tire thickness of the front wheel 11. You can park your bicycle. On the other hand, just by reversing the bicycle on the surface of the front wheel guide plate 8, the tire rolling surface 11 a of the front wheel 11 by the downward inclined surface 8 a of the front wheel guide plate 8 and the tire rolling of the front wheel 11 by the front wheel fixing arm 4 can be performed. The pressed state with the two portions of the moving surface 11a is released. Therefore, since it is not necessary to lift the front wheel 11 side of the bicycle when stopping the parking, even if the front wheel side is heavy due to the load, the bicycle can be separated from the parking device 1 without difficulty.

  As described above, according to the bicycle parking device 1 according to the first embodiment of the present invention, when parking, when the bicycle parking is stopped, the front wheel is lifted like the conventional bicycle parking device according to the first or second example. Because it is not necessary, even if the front wheel is loaded with goods and the front wheel side is heavy, you can easily park and stop parking, greatly reducing the labor of the housewives who went shopping at supermarkets etc. Can contribute. In addition, as in the case of the bicycle parking apparatus according to Conventional Example 2, it is not necessary to utilize the rear stand when parking, so when parking, the operation when stopping the parking can be performed quickly, which is extremely convenient. is there.
