Description

  The present invention relates to a structure of an attached stand for preventing a fall when a bicycle to be parked is standing.

  In recent years, in the traffic environment of crowded urban areas, bad manners of bicycle users are regarded as a problem, and among them, there are many illegal driving acts that pose a danger to pedestrians, but there is no darkness everywhere The dangers caused by the fall of a standing bicycle parked in the city cannot be ignored.

  One of the reasons that three-seater riding, which is necessary for mothers with two or more children, is legally prohibited, is the risk of falling when parked with a child on it. It is a problem.

  When a bicycle is parked in a standing position, a standing stand that is provided rotatably on a rear wheel bearing is generally used. This stand holds the support leg up and behind the rear wheel when driving, and when parking, supports the upper pivoted part of the support leg that is rotated and grounded by locking it with a lock lever. This prevents the legs from jumping up and ensures the grounding in the standing state to prevent danger caused by the fall of the bicycle body.

  However, since the support legs that are raised and held behind the rear wheels during travel are made as narrow as possible so that pedestrians are not damaged during travel, they can rotate when parked. Even if it is locked, there is a risk of falling down because the grounding width of the support legs is narrow, and standing bicycles with children on them are particularly dangerous.

  The present invention is such that the support leg grounding part of the standing stand that is rotatably installed on the rear wheel bearing of the bicycle is held up while driving, and when standing and parked, When the support leg is grounded by rotating the support leg, the extension member of the grounding part automatically extends to both sides and the width of the grounding part becomes wider.Next, when the support leg is locked, the wire connected to the lock lever It is intended to provide a safety stand that prevents the vehicle body from collapsing due to a synergistic effect by fixing the handle to a slightly lateral direction.

  In the present invention, the stand that jumps up and holds on the rear wheel during running has a normal width, so it does not interfere with the pedestrian, and only when the stand is rotated and the grounding part is grounded, the extension members of the grounding part are both Since it extends to the side and becomes wider, the grounding part of the stand is wide and safe and stable, and at the same time, when the stand is locked, the handle is fixed and locked with the interlocking wire, so the synergistic effect makes the bicycle body The risk of falling sideways is prevented and safety is ensured.

  In the present invention, a grounding piece (3a), (4a) is attached to each end of a bottom rod (22) of a support rod (2) pivotably attached to a bracket (1) of a bicycle rear wheel axle. The rod slide rods (3) and (4) fixed so as to be adjustable up and down are slidably held, and between the rod portions (3b) and (4b) of the rod slide rods (3) and (4) facing each other. The wire (6) having both ends of the spring (5) fixed and interposed, and the base end fixed to one collar (3b) is inserted through the spring (5) and the other collar (4b) is inserted. ) Through the adjusting nut (7), and is passed through the cylindrical tube (8) and fixed to the fixed piece (1B) of the curved surface (1A) of the receiver (1).

  Further, a handle lock wire (9) whose base end is fixed to the support rod (2) is connected to the handle lock (12) of the bicycle handle through the adjustment nut of the operating frame (11) of the lock lever (10). It was.

  When the bicycle travels, the support rod (2) is held up in parallel with the ground around the pivoting portion of the receiver (1). In this case, the wire (6) is loosened and the hook ( The contraction tension of the spring (5) between 3b) and (4b) is released and repels, widening the space between the collars (3b) and (4b), and sliding the collar slide rods (3) and (4) Since the grounding pieces (3a) and (4a) at the respective tips are retracted, the stand has a normal width and is safe and unobtrusive to pedestrians.

  When parking the bicycle, when the stand is erected, if the support rod (2) is pivoted around the pivoting part, the wire (6) with the proximal end fixed to the fixed piece (1B) of the receiver (1) as the pivoting operation ) Is guided by the curved surface (1A) and retracted, and the spring (5) gradually shrinks to contract between the flanges (3b) and (4b), and slides the flange slide rods (3) and (4). The parts of the grounding pieces (3a) and (4a) that have been moved are gradually pushed out to the outer sides of the bottom rod (22), and the grounding width of the support rod (2) is widened to extend the grounding pieces (3a) and (4a). Ground safely and stably.

  At the same time, when the stand, that is, the support rod (2) is locked by the lock lever (10), the portion of the handle lock wire (9) that passes through the adjustment nut is pulled by the operation frame (11) of the lock lever (10), Since the handlebar lock (12) is actuated to fix the bicycle handle, the front wheel of the bicycle is also fixed, and the synergistic effect has the effect that the support rod (2) is stably and safely stands.

It is a perspective view of the present invention.
