Description

[Technical field]

[0001] The present invention relates to an attachment device for a bicycle stand and to a bicycle stand equipped with such an attachment device. [Background technology]

[0002] Many of the most widely used bicycles are equipped with a bicycle stand. When parking the bicycle, the bicycle is kept upright by lifting the rear of the bicycle body and setting up the bicycle stand.

[0003] In recent years, with the spread of electrically assisted bicycles, the weight of the bicycles has increased, making it difficult to not only set up the stand but also to handle the bicycle. Patent Document 1 discloses a double-sided bicycle stand structure that not only makes it easy to set up the bicycle stand, but also allows the bicycle to be moved sideways smoothly while the stand is set up.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 11-348856 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, bicycle parking lots in apartment complexes and public facilities may have many bicycles parked in a small space. In order to move a bicycle in such a situation, it is necessary to raise the stand and move the bicycle slightly forward or backward, but this task is difficult if the space between adjacent bicycles is narrow. In this regard, in Patent Document 1, although it is possible to smoothly move the bicycle sideways with the stand upright, it is not possible to move the bicycle forward or backward, so in the end, it is necessary to raise the stand and move the bicycle.

[0006] SUMMARY OF THE PRESENT DISCLOSURE In view of the above problems, the present invention aims to provide a bicycle stand attachment device and a bicycle stand that allow the bicycle to be moved forward and backward while the stand is upright. [Means for solving the problem]

[0007] In order to achieve the above-mentioned objective, the bicycle stand accessory device of the present invention is an accessory device that is attached to a stand equipped on a bicycle, and is characterized in that it comprises a wheel and a support arm that supports the wheel, the support arm being attached to the leg of the stand, and the wheel is activated by tilting the bicycle in a direction perpendicular to the direction of travel, allowing the bicycle to be moved forward and backward while the stand is upright.

[0008] The support arm may further include a fixing member for fixing the support arm to a leg of the stand.

[0009] A bicycle stand according to the present invention is characterized in that it includes a bicycle stand attachment device having the above-mentioned configuration. Effect of the Invention

[0010] According to the present invention, the bicycle can be moved forward and backward while the stand is still upright. [Brief description of the drawings]

[Diagram 2] 1A, 1B, 1C and 1D are a plan view, a front view, a side view and a rear view showing a schematic configuration of a bicycle stand attachment device according to an embodiment of the present invention. [Diagram 3] 13A and 13B are a plan view and a front view showing a schematic configuration of a bicycle stand attachment device according to a modified example. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a bicycle stand attachment device (hereinafter simply referred to as "attachment device") and a bicycle stand (hereinafter simply referred to as "stand") according to the present invention will be described with reference to the drawings.

[0013] As shown in Fig. 1, the stand 100 according to the embodiment is a known double-sided stand that is equipped on a typical bicycle, and has a leg 120 (in the figure, only the portion that comes into contact with the ground is shown enlarged) that is rotatably provided so as to surround the rear wheel (not shown) of the bicycle. The leg 120 is formed from a metal bar and has a roughly U-shape. The accessory device 10 according to the embodiment is attached to the leg 120.

[0014] As shown in FIG. 2, the accessory device 10 includes a wheel 12. The wheel 12 is supported at one end of a support arm 14 via a bearing (not shown). The support arm 14 is made of a metal bar, and has two through holes at the other end. The tip of a U-shaped metal fitting 16, which is a metal round bar formed into a U-shape, is inserted into these two through holes. The tip of the U-shaped metal fitting 16 is a bolt. The accessory device 10 is attached to the leg 120 of the stand 100 by clamping the leg 120 between the support arm 14 and the U-shaped metal fitting 16 and tightening a nut 18 on the bolt part at the tip of the U-shaped metal fitting 14. In this manner, in this embodiment, the U-shaped metal fitting 16 and the nut 18 constitute a fixing member for fixing the support arm 14 to the leg 120.

[0015] In this embodiment, the attachment device 10 is attached to the left side of the bicycle in the traveling direction, with the center of rotation of the wheel 12 inclined relative to the wheel axis of the rear wheel of the bicycle, more specifically, with the center of rotation of the wheel 12 being approximately parallel to the wheel axis of the rear wheel of the bicycle in a plan view and inclined vertically relative to the wheel axis in a front view. The attachment device 10 is attached in a position such that a small gap S (FIG. 1(a)) is formed between the ground surface and the wheel 12 when the stand 100 is in an upright state. The attachment device 10 attached to the leg 120 in this manner is in a state in which the wheel 12 does not perform its intended function (invalid state) when the stand 100 is in an upright state. On the other hand, when the bicycle is tilted toward the side where the attachment device 10 is attached (left side) with the stand 100 in an upright state, the wheel 12 touches the ground and is in a state in which it can perform its intended function (enabled state). As a result, even when the stand 100 is in an upright state, the wheel 12 of the attachment device 10 functions as a substitute for the rear wheel, and movement in the forward and backward directions is possible.

[0016] Thus, according to this embodiment, the bicycle body can be moved forward and backward while the stand 100 is in the upright position, making it easy to park the bicycle in a small space such as a bicycle parking lot in an apartment building or public facility. In other words, it is convenient not only when taking the bicycle out of the bicycle parking space, but also when storing the bicycle in the bicycle parking space.

[0017] The above describes the bicycle stand accessory device and bicycle stand of the present invention based on an embodiment, but the present invention is of course not limited to the above-mentioned form and may be embodied in, for example, the following modified form.

[0018] <Modification> (1) In the above embodiment, the U-shaped bracket 16 and the nut 18 are used as fixing members, so that the accessory device 10 is detachable from the leg portion 120. However, the accessory device 10 may be fixed to the leg portion 120 by welding or the like.

[0019] (2) In the above embodiment, the accessory device 10 is attached to the leg 120 in a position where the center of rotation of the wheel 12 is inclined with respect to the axle of the rear wheel of the bicycle, but the wheel 12 may be attached in a position where the center of rotation of the wheel 12 is generally parallel to the axle of the rear wheel of the bicycle. In addition, the center of rotation of the wheel 12 may be generally parallel to the axle of the rear wheel of the bicycle when the wheel 12 is in an inactive state where the wheel 12 does not perform its intended function, or when the wheel 12 is in an active state where the wheel 12 is in contact with the ground and can perform its intended function. In short, the attachment position of the accessory device 10 to the leg 120 is not particularly limited as long as the bicycle can move in the fore-and-aft direction while the stand 100 is in an upright position.

[0020] (3) In the above embodiment, the stand 100 was attached in a position where a small gap was formed between the ground and the wheel 12 when the stand 100 was upright, but it may be attached in a position where the wheel 12 touches the ground together with the legs 120. Even in this case, the wheel 12 is disabled when the legs 120 are on the ground, and the wheel 12 is still enabled by tilting the bicycle body.

[0021] (4) In the above embodiment, the support arm 14 of the attachment device 10 is a straight rod, but this is not limited to this. For example, it may have a shape with a bent or curved portion. The shape of the support arm can be changed as appropriate depending on the shape of the stand to which it is attached.

[0022] (5) The outer surface of the support arm that comes into contact with the leg 120 may be treated to strengthen the fixation. For example, as in the attachment device 20 shown in Fig. 3, a notch 22 having a shape that matches the outer shape of the leg 120 may be formed in the outer surface of the support arm 14, or a surface treatment may be applied to increase the coefficient of friction of the contact portion with the leg 120.

[0023] (6) In the above embodiment, the wheels 12 are elliptical with rounded corners, but the shape of the wheels is not particularly limited. For example, spherical wheels may be used. The same applies to the size of the wheels and the presence or absence of bearings. In short, any member that can roll to determine the direction of travel and move forward and backward can perform the same desired function as the wheels described above.

[0024] The present invention can be implemented in various forms that include improvements, modifications, or variations based on the knowledge of a person skilled in the art without departing from the spirit of the present invention. In addition, the present invention can be implemented in a form in which any of the invention-specific features are replaced with other technologies within the scope of the same action or effect. [Industrial Applicability]

[0025] The bicycle stand attachment device and bicycle stand of the present invention can be used not only for ordinary two-wheeled bicycles, but also for bicycles with three or more wheels. Of course, they can be used not only for heavy bicycles such as electrically assisted bicycles, but also for general bicycles in general. [Explanation of symbols]
