Description

  The present invention relates to a bicycle parking apparatus that is installed to park a large number of bicycles in front of a station, an apartment house, a public hall, a park, and the like.

  2. Description of the Related Art Conventionally, various types of bicycle parking apparatuses are installed in front of stations, apartment houses, public halls, parks and the like to park a large number of bicycles.

Recently, in order to efficiently park a large number of bicycles in a limited space, a large number of bicycle parking stands for placing bicycles are arranged in the horizontal direction, and these bicycle parking stands are installed on the floor surface. A sliding-type bicycle parking device that can slide right and left along the rail is used.
Furthermore, in order to be able to park two bicycles in one space, the bicycle parking frame is arranged in two upper and lower stages, the bicycle parking frame arranged in the upper stage can be raised and lowered, and the bicycle parking frame arranged in the lower stage. A vertical two-stage bicycle parking apparatus is also employed in which the wheel rack is slidable left and right along the rail.

The sliding bicycle parking device and the vertical two-stage bicycle parking device, wherein the bicycle parking frame that slides horizontally along the rail is a sliding member that is slidably fitted to the rail on the bottom surface of the front side portion. And a caster for rolling the floor surface on the bottom surface of the rear side.
The user of the bicycle parking apparatus first places the front wheel of the bicycle on a guide plate disposed at the rear end of the bicycle parking base, moves the front wheel forward as it is, and places it on the bicycle parking base. Move the wheel until it rests on the parking rack, and place the bicycle completely on the parking rack.

  However, in the bicycle parking frame having the above configuration, the bicycle parking frame is extremely easy to move in the horizontal direction when the bicycle enters or leaves the bicycle parking frame, and the user enters and exits the bicycle. It was inconvenient to let me.

Therefore, a tilting foot brake plate is arranged on the side of the rear side of the bicycle parking frame to prevent the bicycle parking frame from moving in the horizontal direction when the bicycle enters and leaves the bicycle parking frame. Bicycle parking devices have been developed and are commercially available.
According to this bicycle parking apparatus, when a bicycle enters and leaves the bicycle parking frame, a user steps on the foot brake plate with one foot, and the rubber member fixed to the lower surface of the foot brake plate contacts the floor surface. By doing so, the horizontal movement of the bicycle parking frame can be prevented.

  However, in a bicycle parking device with a foot brake plate, it is necessary to move the bicycle into and out of the bicycle mount while stepping on the foot brake plate with one foot, which will result in an unstable posture and movement. Especially, for women and children, there is a risk of falling and the like.

Therefore, in order to prevent horizontal movement of the bicycle parking frame when the bicycle enters and leaves the bicycle parking frame without such a danger, a bicycle parking apparatus provided with a caster braking mechanism has been proposed. (See Patent Document 1).
According to this bicycle parking apparatus, when the front wheel F of the bicycle B is placed on the tread plate 21, the caster braking mechanism 24 automatically brakes the caster 15 to prevent the bicycle parking base 13 from moving in the horizontal direction. The person is not forced to move in an unstable posture and movement, and the danger is small.
