The slide guide 5 is fixed parallel to the ground. The slide guide 5 is provided with a slide portion 6 that can slide back and forth. Further, a cam mechanism 7 is attached to the rear end of the slide guide 5 so that when the slide part 6 is slid backward, the slide part 6 can be turned up and down by the cam mechanism 7. ing. Further, a front end of a gas spring 8 is pivotally attached to a front lower end of the cam mechanism 7, and a rear end of the gas spring 8 is pivotally attached to a bottom upper surface of the slide guide 5. Rollers 9, 9 are mounted on the front of the slide portion 6, and the rollers 9, 9,... Are configured to operate in grooves (not shown) provided in the slide guide 5. Therefore, the slide portion 6 is formed so that the slide guide 5 can slide smoothly. Thus, when using the bicycle parking device 1, first, the slide portion 6 accommodated in the slide guide 5 is hooked backward and pulled out. At this time, since the rollers 9, 9,... Are mounted on the slide portion 5, the slide of the slide portion 5 is smoothened. Then, the front portion of the slide portion 6 moves to the rear portion of the slide guide 5, and the slide portion 6 is rotated downward by the cam mechanism 7. At this time, since the gas spring 8 presses the back surface of the cam mechanism 7 to urge the slide portion 6 upward, the sudden fall of the slide portion 6 is prevented. Further, the slide portion 6 is lowered, and the rear end of the slide portion 6 is brought into contact with the ground, and a bicycle or the like is mounted on the upper portion of the slide portion 6.

The above-mentioned conventional bicycle parking system is constructed such that a gas spring mounted inside a slide guide is mounted on a cam mechanism so that the slide portion can be urged upward. However, since a long stroke of the gas spring cannot be secured, there is a case where the pressing force upward of the slide portion is insufficient and the slide portion is suddenly lowered. Further, since the bicycle parking machine cannot be stopped at the position where the slide portion has been raised, the slide portion may be inadvertently lowered when the slide portion is hooked, thereby causing a problem in safety. Therefore, there is a technical problem to be solved in order to prevent the slide portion of the bicycle parking device from suddenly descending and to prevent the slide portion from unexpectedly descending to improve the safety of the bicycle parking device. It is an object of the present invention to solve the problem.

Rollers 26, 26... Are mounted on the front and rear of the roller cover 25 by pins 27, 27 so that the inside of the slide guide 23 can be operated. The rollers 26, 26 ...
Is formed to the maximum size which is substantially the same as the vertical width of the slide guide 23. Therefore, when manipulating the inner surface of the slide guide 23, even if there is play on the inner surface due to corrosion, painting, or the like, the large-diameter rollers 26, 26 ... absorb the play and smoothly move the slide guide 23. Can be slid, and noise at the time of the sliding can be significantly prevented. Reference numeral 28 denotes the slide guide 2.
3 is a roller mounted on the rear part, which rotates in contact with the back surface of the slide part 24, and
Sliding is possible. On the other hand, a front intermediate portion of the slide portion 24 is pivotally connected to a rear portion of the roller cover 25 by a pin 27. Further, a spring cover 29 is provided upright at the front end of the roller cover 25. A distal end of a gas spring 30 is pivotally attached to the upper end of the spring cover 29 so as to be able to rotate back and forth. The rear end of the gas spring 30 is pivotally connected to the front end of the slide portion 24. On the other hand, as shown in FIGS. 2 and 4, balls 31, 31 are slidably mounted on the inside of the front part of the slide portion 24, and the balls 31, 31 are laterally inserted through holes. The balls 31, 31 protrude and are urged sideways by a spring (not shown). Furthermore,
Holes 32, 32 are formed in the roller cover 25 at positions facing the balls 31, 31 so that the balls 31, 31 can be fitted and locked in the holes 32, 32. Reference numeral 33 in the figure denotes a holding pipe, which prevents the bicycle from falling when the bicycle is mounted above the slide portion 24. Thus, when using the bicycle parking machine 20, first, the slide unit 2 housed in the slide guide 23 is used.

The engagement between the balls 2 and 32 and the balls 31 and 31 is released, and the slide portion 24 descends. Further, when the slide portion 24 is lowered, the gas spring 30 presses the distal end portion of the slide portion 24 downward, so that the slide portion 24 is urged upward via the pin 27 of the rotation fulcrum. Therefore, the sliding portion 24 does not suddenly descend, and the descending operation can be performed safely. Further, since the gas spring 30 is mounted upright at an angle of substantially 90 degrees with respect to the slide portion 24 by the spring cover 29, the stroke of the gas spring 30 is secured to the maximum and the The pressing force can be improved. Therefore, a sudden downward movement of the slide portion 24 is prevented by the upward pressing force of the gas spring 30 against the slide portion 24, thereby improving safety. When the slide portion 24 is lowered, as shown in FIG.
Is compressed, and the action point A of the gas spring 30 is
And the rotation fulcrum of the slide portion 24 are substantially linear,
The upward pressing force of the slide portion 24 decreases, and the slide portion 24 can be stopped at the lowered position. Then, the bicycle is mounted on the upper portion of the slide portion 24 and the slide portion 24 is raised. At this time, as described above, since the gas spring 30 presses the slide portion 24 upward, the slide portion 24 can be easily raised. When the slide portion 24 rises to a position parallel to the ground, the balls 31, 31 and the holes 3
The slide portion 24 can be held at the raised position by the engagement of the slide portions 24 with each other. Then, the slide portion 24
By pressing the slide guide 23 and sliding the slide portion 24 forward, the bicycle is accommodated above the bicycle parking device 20. When the bicycle is taken out, the above operation can be repeated to safely and easily take out the bicycle. As shown in FIGS. 6 and 7, the slide guides 23,
.. Are connected to regulate the movement of the slide guides 23, 23. Therefore, the connection improves the safety of the bicycle storage operation. The present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified ones.

According to the first aspect of the present invention, a roller cover that slides on a slide guide is provided, and a front intermediate portion of a slide portion is pivotally attached to a rear portion of the roller cover. And, since a spring is attached to the upper end of the spring cover and the front end of the slide portion, which are erected at the front end of the roller cover, the front end of the slide portion is configured to be pressed downward. The slide portion is urged upward via a pivot point. Since the position where the spring is extended is supported at 90 degrees with respect to the slide portion, the maximum compression stroke width of the spring can be ensured.
Therefore, when the slide portion is rotated, the slide portion is urged upward, so that it is possible to improve safety, for example, by preventing a sudden fall of the slide portion. Further, a complicated cam mechanism as in the related art is not required, which can contribute to cost reduction. In the invention according to claim 2, a stopper slidable left and right is mounted at an appropriate position on the front part of the slide portion.
And, while urging the stopper to the side,
The stopper is configured to be able to engage and disengage with a locking hole formed in the roller cover. Therefore, when the slide portion is raised, the stopper and the locking hole are engaged, and the slide portion can be stopped at a position parallel to the raised ground. Further, when the slide portion is pressed downward, the engagement between the stopper and the locking hole is released, and the slide portion can be rotated downward. According to the third aspect of the invention, the upper and lower widths of the slide guide formed of C-shaped steel or the like and the diameter of the roller inserted into the slide guide and mounted on the roller cover are formed to have substantially the same length. Therefore, the roller is formed to have the largest diameter, so that the sliding of the sliding portion can be made as smooth as possible, and noise at the time of the sliding can be prevented.
