BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an upper and lower two-stage type bicycle parking device for parking a bicycle or a minibike.

[0002]

2. Description of the Related Art As an upper and lower two-stage bicycle parking device, for example,
There is one disclosed in Japanese Utility Model Laid-Open No. 6-85869. In this bicycle parking apparatus, as shown in a side view of the main part of FIG. 8, a groove-shaped fixed frame 50 having a lip section in the upper stage side is substantially forwards and backwards at a predetermined height position from the floor of a bicycle parking lot by a pillar or the like. A guide rail 51, which is supported horizontally and has a rear end portion 51a inclined rearward and upward, is assembled in the groove of the fixed frame 50 by welding or the like. On the other hand, the movable frame 52 on which the bicycle is mounted is equipped with a rolling roller 53 at the front end thereof, and the rolling roller 53 is incorporated into the guide rail 51 so as to be movable, so that the movable frame 52 is provided inside the groove of the fixed frame 50. Is slidably fitted back and forth. A support member 54 that supports the movable frame 52 is attached to the rear end of the fixed frame 50 so as to be vertically rotatable about a shaft 55. A portion of the support member 54 rearward of the shaft 55 is constantly urged to rotate upward by a gas spring 56 provided inside the rear end of the fixed frame 50.

In parking, when the movable frame 52 pushed into the fixed frame 50 is horizontally pulled out to the rear of the fixed frame 50 and then pushed down together with the support member 54, the movable frame 52 is inclined rearward and downward. The bicycle is mounted on the movable frame 52 that is inclined rearward and downward. After mounting, the movable frame 52 is pushed upward together with the support member 54 to be horizontal, and then the fixed frame 5
Push it to zero. Movable frame 5 when lowering the bicycle
Pull out 2 from the fixed frame 50 and push it down,
The movable frame 52 is inclined rearward and downward. The bicycle is lowered from the movable frame 52 which is inclined rearward and downward.

[0004]

According to the above conventional bicycle parking apparatus, the rear end portion 51a of the guide rail 51 in the fixed frame 50 is assembled by welding or the like so as to be inclined rearward and upward. Pushing down the movable frame 52 pulled out rearward from the fixed frame 50,
The installation space is narrowed by making it possible to draw a substantially vertical linear movement locus without the rear end of the movable frame 52 projecting backward in a large arc shape when pushed up. In addition, the support member 54 of the movable frame 52
As a means for constantly urging the vehicle upward, a movable frame 52 is mounted on the movable frame 52 by enclosing gas in the cylinder and adopting a gas spring 56 utilizing the repulsive force due to the gas pressure. Then, when the movable frame 52 is pushed down, the movable frame 52 does not suddenly lower and is pushed down gently against the biasing force of the gas spring 56. . However, the process of assembling the guide rail 51 having the rear end portion 51a inclined rearward upward in the fixed frame 50 made of the channel member with the lip section by welding is complicated, and the rear end of the guide rail 51 is complicated. Due to the inclination of the portion 51a, the fixed frame 50 has a high height H of the left and right side walls 57, that is, it is necessary to prepare a grooved member with a special cross-section lip having a deep groove. Is expensive. Further, the gas spring 56 has a cylinder 58.
One end of the rod is connected to the fixed frame 50 and the end of the rod 59 is connected to the support member 54 by a pin 60, but this attachment is cumbersome and very expensive. The present invention has been made in view of such a problem, and it is possible to reduce the material cost and the processing cost while ensuring a narrow installation space and a light and safe push-down operability of the movable frame. The object is to provide a bicycle parking device.

[0005]

A bicycle parking apparatus according to the present invention is supported substantially horizontally by a pillar or the like at a predetermined height position above the floor surface, and is installed at the upper end of a bottom wall, left and right side walls, and left and right side walls that are long in the front-rear direction. A groove-shaped fixed frame having a lip with a lip attached in the direction, and a pair of front and rear wheel stoppers, and a movable frame having a groove-shaped cross section having a bottom wall and left and right side walls longer in the front-rear direction than the fixed frame. . The movable frame is slidably fitted in the groove of the fixed frame in the front-rear direction, and guide grooves provided in the front-rear direction outside the left and right side walls of the movable frame are provided in a pair of left and right sides provided at the rear end of the fixed frame. It is slidably fitted to the idle roller. A swing base end portion of the swing frame is pivotally attached to the front end side of the movable frame so as to be capable of swinging back and forth by a pivot, and a swing tip end portion of the swing frame extends below a bottom wall of the movable frame. The rocking tip portion is provided with a pair of left and right rolling rollers that run and rotate in the front-rear direction between the lip in the fixed frame and the bottom wall. A tension coil spring is stretched between a portion of the movable frame rearward of the pivot and the swing frame, and a tension force of the tension coil spring causes a rear side of the movable frame on the idler roller to serve as a fulcrum. In addition, the swinging tip portion of the swinging frame is always urged upward, and the swinging tip end portion of the swinging frame is attracted to the bottom wall of the movable frame at a position rearward of the pivot. A rear stopper is provided at the front end of the guide groove of the movable frame to stop the movable frame by contacting the idler roller when the movable frame reaches the rear slide end position. At the front end of the fixed frame, at the slide end position in the forward direction of the movable frame,
A front stopper that comes into contact with the front end of the movable frame to stop the movable frame, and a floating prevention member that prevents the front end of the movable frame from floating up are provided. The rear stopper is positioned so that the rear end of the movable frame is at a height where it floats above the floor when the movable frame is slid backward and slanted backward.

[0006]

When the movable frame is pushed deepest into the fixed frame, the front end of the movable frame comes into contact with the front stopper at the front end of the fixed frame and enters under the floating prevention member. Therefore, the movable frame does not unexpectedly float up when the bicycle is parked. If a downward force is applied while pulling out the movable frame from such a state, as soon as the front end of the movable frame comes out of the rear of the floating prevention member to the outside of the rear, the front end of the movable frame is lifted by the height at which the swing frame stands up. Can be levitated from the fixed frame. Also, when pushing the rear end of the movable frame that has been pulled out and pushing it forward on the fixed frame, the front end of the movable frame can be floated above the fixed frame. In this way, when pushing and pulling the movable frame on the fixed frame, by moving the front end of the movable frame forward and backward, the rear end of the movable frame draws a movement trajectory (curve) as front as possible. Can be

[0007] When the movable frame is pushed up from the state of being pulled down rearward, the guide groove of the movable frame slides on the idle roller, and the rolling roller of the swing frame rolls straight forward in the fixed frame. Meanwhile, the movable frame is smoothly pushed forward on the fixed frame. At this time, the pulling force of the tension coil spring applied to the movable frame assists the pushing up, so that the force required for pushing up is small even if the bicycle is mounted on the movable frame.

Even when the movable frame is pulled rearward from the fixed frame, the guide groove of the movable frame slides on the idler roller, and the rolling roller of the swing frame rolls straight backward in the fixed frame to move. The frame is gradually pulled backwards while being smoothly pulled out backwards on the fixed frame. At this time, since the tensile force of the tension coil spring is applied to the movable frame in the upward rotation direction, the movable frame is pulled out to the rear of the fixed frame and pushed down by a gentle action against the biasing force of the tension coil spring.

The tension coil spring constantly urges the swinging tip of the swinging frame to draw it toward the rear portion from the pivot of the bottom wall of the movable frame. Therefore, when the movable frame is pushed forward, the swinging frame is moved. There is no problem that the oscillating tip end of the movable frame comes under the floating prevention member prior to the front end part of the movable frame, and the front end part of the movable frame can be always advanced and advanced.

[0021]

According to the present invention, when the movable frame is pushed and pulled on the fixed frame, the front end of the movable frame can be lifted from the fixed frame by the rising height of the swing frame and moved back and forth. As a result, the movement trajectory of the rear end of the movable frame can be biased forward,
Therefore, the installation area can be reduced. The rolling roller of the swinging frame that exerts a levitation action on the front end of the movable frame is sufficient by rolling it straight in the groove of the fixed frame in the front-rear direction. There is no need to specially assemble a guide rail with a rising slope, and there is no need to specially elevate the left and right side walls to deepen the groove, so a fixed frame can be constructed using the existing grooved steel with a cross-section lip as it is, Material and processing costs can be significantly reduced as compared with the conventional example.

The tension coil spring stretched between the movable frame and the swing frame can easily push up the movable frame on which the bicycle is mounted with a small force, and when the movable frame is pushed down, it is gentle against the biasing force of the tension coil spring. It can be pushed down safely with various movements. The tension coil spring is cheaper than the gas spring and can be easily attached.

Since the rear end of the movable frame is made to float above the floor when the movable frame is tilted rearward and downward, when the movable frame is pushed up, the waist of the movable frame does not bend down so that the comfortable posture of the movable frame is maintained. The rear end can be lifted.
