Description

  The present invention relates to a bicycle parking apparatus, and more particularly to a bicycle parking apparatus for allowing a bicycle to be parked in two separate upper and lower stages.

  The bicycle parking device for separating the bicycle into two upper and lower stages has a fixed beam horizontally fixed to the upper end of the upright column, and secures a bicycle storage space below the fixed beam. A movable beam having a length that can be mounted is stored in the fixed beam so as to be able to advance and retract in the front-rear direction. It is configured to be able to rotate in an inclined state where it can be taken in and out. When the bicycle is parked, the movable beam pulled out in a horizontal posture by a predetermined length is pushed down at the rear end position of the fixed beam to convert it into an inclined posture, and the bicycle is pushed onto the movable beam converted into the inclined posture. Next, the bicycle is parked by lifting the rear end of the movable beam, turning it upward and reversing it to a horizontal position, and then pushing the movable beam toward the fixed beam.

  In order to take out a bicycle that is parked, the movable beam is pulled out to the rear end side of the fixed beam in a horizontal posture for a predetermined length, and then converted into an inclined posture by pushing down the movable beam. This is done by the procedure of removing the bicycle from the movable beam.

  In such a bicycle parking device, when the bicycle is parked, the bicycle is pushed onto the movable beam converted into the tilted posture, and after that, the rear end side of the movable beam is lifted and rotated upward to be horizontal. A bicycle parking operation that reverses the posture is required, and when the bicycle is taken out, a take-out operation is required in which the movable beam pulled out by a predetermined length in a horizontal posture is pushed down and rotated downward to convert it into an inclined posture. Therefore, the lifting force when reversing the movable beam from the tilted position to the horizontal position during parking operation is reduced to reduce the burden on the operator, and the movable beam suddenly drops from the horizontal position to the tilted position during removal. Therefore, it is necessary to suppress the rotation.

  Therefore, when the movable beam is reversed from the tilted posture to the horizontal posture using the gas cylinder, the lifting force of the operator is applied by urging the movable beam upward with the elastic force of the gas cylinder. When the movable beam is rotated from the horizontal position to the inclined position by reducing the load, the gas beam is contracted to provide resistance to the downward rotation and the movable beam is rotated downward suddenly. There has been proposed a bicycle parking device configured to suppress this (see, for example, Patent Document 1).

  As shown in FIG. 22, the bicycle parking device described in Patent Document 1 includes a fixed-position roller 52 serving as a fulcrum when the movable beam 51 is rotated from the horizontal posture to the inclined posture at the rear end portion of the fixed beam 50. A movable roller 55 is provided on both sides of the distal end of the movable link 53, the rear end of which is pivotally connected to a position near the distal end of the movable beam 51. A holding groove 56 into which the moving roller 55 is fitted is formed in the fixed beam 50 at a tilt angle (tilt posture) at which the movable link 53 can be put in and out of the bicycle, and the pivot position of the movable link 53 is formed on the lower surface of the movable beam 51. A stopper hinge 57 provided at a position closer to the rear end side than the moving roller mounting shaft 57 of the movable link 53 is connected by a gas cylinder 59.

  According to the bicycle parking apparatus described in Patent Document 1 configured as described above, the movable link 53 is accommodated in a horizontal state inside the movable beam 51, and the movable beam 51 is a fixed position roller 52 and a movable roller of the movable link 53. When the movable link 53 is pulled out from the front stage of parking where the gas cylinder 59 is extended by being supported in the fixed beam 50 and extended in the fixed beam 50, the stopper hinge 57 collides with the fixed position roller 52 when parking. The extraction of the movable beam 51 stops. Further, in this state, when the movable beam 51 in the horizontal posture is rotated to the inclined posture so that the movable beam 51 is inclined at a predetermined angle, the moving roller 55 provided on the distal end side of the movable link 53 holds the both-side guide rails 54. The movable beam 51 is held at a predetermined inclination angle by being fitted into the groove 56.

  That is, the parking device described in Patent Document 1 is configured such that the collision of the stopper hinge 57 and the fixed-position roller 52 is repeated to stop the movable link 53 every time the movable link 53 is pulled backward during parking. Therefore, the impact load generated at each collision acts on both the stopper hinge 57 and the fixed position roller 52. Even if the impact load has a magnitude within the designed range, if it repeatedly acts on both the stopper hinge 57 and the fixed-position roller 52, both may be deformed or damaged over time.

  In particular, the deformation or damage of the stopper hinge 57 adversely affects the smooth expansion and contraction of the gas cylinder 59 connecting the tip of the piston rod to the stopper hinge 57, reducing the lifting force of the operator and reducing the burden. Therefore, the urging force of the turning elastic force is reduced to increase the burden on the operator, or the resistance to suppress the sudden downward turning of the movable beam 51 is weakened. Since the downward rotation occurs, there is a problem that the burden on the operator when lifting the movable beam 51 is reduced and the reliability for suppressing the rapid downward rotation of the movable beam 51 is low.

JP 2007-90964 A

  The present invention has been made in view of such circumstances, and by ensuring smooth expansion and contraction of the gas cylinder over a long period of time, the burden on the operator when lifting the movable beam is reduced and the movable beam is rapidly turned downward. It is an object of the present invention to provide a bicycle parking device that can improve the reliability of the movement suppression.

  According to the first aspect of the present invention, a fixed beam that is horizontally installed with the tip side being cantilevered by a column, and a length on which the bicycle can be placed, can be moved forward and backward in the fixed beam. And a gas cylinder that extends in the front-rear direction in a bicycle parking apparatus that can be rotated to an inclined posture that allows the bicycle to be taken in and out by pulling the movable beam backward. The gas cylinder storage frame is provided and fixed to the fixed beam, and the inclined posture holding surface comprising an inclined surface that is inclined upward and downward toward the rear end of the gas cylinder storage frame. The tip is pivotally connected to the first fulcrum position that is exposed to the rear of the fixed beam and is exposed above the inclined posture holding surface and closer to the tip. And a rotating arm that supports the lower surface of the movable beam in a horizontal position so that the lower surface of the movable beam can move in the longitudinal direction. A locking claw portion formed on the rear end portion by the back of the main body is pivotally connected to the second fulcrum position of the rear end portion of the moving arm and is urged by the elastic member. A locking lever that rotates in the range of the release position is provided, and is formed extending in the width direction of the movable beam while avoiding interference between the rear end surface of the rotating arm and the inner surface of the movable beam at a predetermined position on the movable beam. The abutting plate constitutes a first stopper mechanism for restricting the forward movement of the movable beam at the front end position, and the locking claw portion of the locking lever and the locked portion provided on the movable beam The backward movement is restricted at the rear end position and the movable beam from the rear end position is restricted. A second stopper mechanism that allows advancement, and a downwardly extending driven piece provided at the tip of the rotating arm is made to face the inner side of the rear end of the gas cylinder housing frame so that the driven piece and the gas By connecting the cylinders to each other via a link mechanism, when the movable beam is lifted from the inclined position to the horizontal position, the upward elastic force is applied to assist the lifting force and the movable beam is The present invention relates to a bicycle parking apparatus that is configured to increase a downward resistance to suppress a sudden downward rotation of a movable beam when being pushed down from a horizontal posture to an inclined posture. By providing the present invention, the above-mentioned problems have been successfully solved.

  According to a second aspect of the present invention, in the first aspect of the present invention, the downward groove type is formed outside the first fulcrum position and the second fulcrum position of the rear end of the rotating arm on both sides in the width direction. The lower surface of the movable beam supports the lower surface of the ceiling so that it can move forward and backward, rolls, and the upper surface of the rail that extends horizontally inward in the width direction from the lower ends of both vertical walls extending vertically downward from both widthwise ends of the ceiling. The present invention relates to a bicycle parking device including a rolling guide roller.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, at least one of the inclined posture holding surface and the rotating arm is rotated from a horizontal posture to an inclined posture. The present invention relates to a bicycle parking apparatus provided with a first elastic body that relieves an impact at the time of contact between a rotating arm and an inclined posture holding surface.

  According to a fourth aspect of the present invention, in the first, second, or third aspect of the present invention, the rear end surface of the rotating arm constituting the first stopper mechanism and the abutting plate The present invention relates to a bicycle parking apparatus in which at least one of them is provided with a second elastic body that relieves an impact when the advance of the movable beam is restricted at the front end position.

According to the first aspect of the present invention, when the movable beam is lifted up so as to be reversed from the tilted posture to the horizontal posture, the pivot arm supporting the movable beam moves backward with the first fulcrum position as the pivot center. By rotating, the driven piece at the tip rotates in the same direction as the rotating arm. As a result, the gas cylinder expands, and the extension force is transmitted to the driven piece at the tip of the rotation arm via the link mechanism, and the upward rotation elastic force that rotates the rotation arm rearward is urged. Is done. This upward turning elastic force assists the lifting force of the movable beam supported by the turning arm, so that the burden on the operator can be reduced by reducing the lifting force of the operator.
When the movable beam is pushed down so as to convert it from a horizontal posture to an inclined posture, the pivot arm supporting the movable beam pivots downward from the first fulcrum position to the center of the gas cylinder. The tilted posture holding surface provided at the rear end of the frame is brought into contact with the movable beam to be converted into a tilted posture, and the driven piece at the tip of the rotating arm is rotated in the same direction as the rotating arm, via a link mechanism. Shrink the gas cylinder. As described above, the contraction of the gas cylinder provides resistance to the downward rotation of the movable beam, thereby suppressing the rapid downward rotation of the movable beam.
Further, when the movable beam is pulled out backward when parking, the movable beam is engaged by the engagement between the latching claw portion of the latching lever constituting the second stopper mechanism and the latched portion provided on the movable beam. Since the rearward movement is restricted at the rear end position, even if the engagement between the locking claw and the locked portion is repeated every time the movable beam is pulled backward, the impact at this time is It has no effect on the link mechanism and gas cylinder. As a result, the deformation and damage of the link mechanism and gas cylinder over time can be avoided, and smooth expansion and contraction of the gas cylinder can be secured over a long period of time, reducing the burden on the operator when lifting the movable beam, and the downward movement of the movable beam It becomes possible to improve the reliability with respect to suppression of rotation.

According to the second aspect of the invention, the downward groove type movable beam is supported so that the lower surface of the ceiling portion can be advanced and retracted by the guide roller, and the guide roller is configured to roll on the upper surface of the rail portion. In addition, both the operation of pulling the movable beam backward from the front end position to the rear end position and the operation of pushing forward from the rear end position to the front end position, that is, the movable beam advance and retreat operation can be performed smoothly. It is also possible to prevent the movable beam from falling off the rotating arm and the fixed beam.
Such an effect of preventing the movable beam from falling off is also exhibited during the lifting operation on the rear end side of the movable beam when the movable beam is reversed from the inclined posture to the horizontal posture. In other words, the reversal behavior of the movable beam is transmitted from the rail portion to the rotating arm without dropping through the guide roller, and the rotating arm follows the movable beam to reverse the tilted posture to the horizontal posture. Is possible.

  According to the invention of claim 3, the pivoting arm pivots backward and downward with the first fulcrum position as the pivot center by performing a push-down operation so as to convert the movable beam from a horizontal posture to an inclined posture. The impact when it comes into contact with the posture holding surface is relaxed by elastic absorption by the first elastic body. For this reason, it is possible to avoid the deformation or damage of the rotating arm and the inclined posture holding surface and to eliminate the impact sound.

  According to the fourth aspect of the present invention, the movable beam at the rear end position that is reversed from the tilted posture to the horizontal posture is pushed forward to the front end position, so that the rear of the rotary arm that constitutes the first stopper mechanism. The end face and an abutting plate formed at a predetermined position on the inner surface of the movable beam come into contact with each other, and the impact when the advance of the movable beam is restricted at the front end position is elastically absorbed by the second elastic body and alleviated. Therefore, it is possible to avoid the deformation or damage of the rear end surface of the rotating arm and the abutting plate and to eliminate the impact sound.

As a result, as shown in FIG. 17, the upper end surface of the locking portion 10 c of the locking lever 10 is pressed downward by the lower surface of the ceiling portion 4 a of the movable beam 4, and is pushed down slightly against the bias of the elastic member 25. . That is, the locking lever 10 is slightly rotated counterclockwise around the fulcrum pin 9 as a rotation center. When the movable beam 4 is further pushed forward in this state, the lower surface of the ceiling portion 4a of the movable beam 4 is supported by the guide roller 23 so as to be able to advance and retreat, as shown by a two-dot chain line in FIG. The upper surface of the pair of rail portions 4c can be rolled, and the movable beam 4 is covered from the upper side so as to be movable back and forth in the front-rear direction with respect to the fixed beam 3. The movable beam 4 is pushed forward by a first end constituted by a rear end surface 8l of the sandwiching plate 8h (specifically, the front end side 21b of the second elastic body 21) and the abutting plate 15 on the movable beam 4 side. The movement is terminated by the action of restricting the forward movement of the movable beam 4 by the stopper mechanism 22 at the front end position. Specifically, when the abutting plate 15 comes into contact with the distal end side 21b of the second elastic body 21, the pushing of the movable beam 4 forward is completed.

  As shown in FIG. 18, at the rear end portion of the gas cylinder housing frame 5, the leveling bolt 26 is connected to the welding nut 17d fixed to the surface of the other side 17c of the inclined posture holding member 17 from the through hole h4 side. And the tip thereof protrudes from the welding nut 17d so that the rotating arm 8 can come into contact with the connecting portion 11a of the driven piece 11. By adjusting the amount of protrusion from the welding nut 17d at the tip of the level adjustment bolt 26, the height level of the rear end portion of the rotating arm 8 can be adjusted. Specifically, when the protruding amount is increased, the position of the rear end portion of the rotating arm 8 is increased, and when the protruding amount is decreased, the position of the rear end portion of the rotating arm 8 is decreased. The height level of the rear end of the rotating arm 8 after adjustment is adjusted by screwing a fastening nut 26a, which is screwed into the welding nut 17d in advance, toward the other side 17c. The nut 17d can hold the other side 17c firmly.

Hereinafter, the operation of the bicycle parking apparatus according to the present invention having the above-described configuration will be described.
In the state shown in FIG. 1, the handle 4h is held and the movable beam 4 is pulled out horizontally (to the left in FIG. 1) horizontally. The extraction of the movable beam 4 is terminated by the action of restricting the backward movement of the movable beam 4 by the second stopper mechanism 24 at the rear end position. Specifically, when the locked portion 16 on the movable beam 4 side reaches the upper side of the locking claw portion 10c of the locking lever 10, the locking lever 10 urges the elastic body 25 as shown in FIG. As a result, the fulcrum pin 9 is rotated clockwise around the rotation center, the locking claw portion 10c enters the locked portion 16, and the locking surface 10f abuts against the tip 16a of the locked portion 16 to engage. End by stopping. In this way, in a state where the movable beam 4 is drawn horizontally rearward, the gas cylinder 6 extends as shown in FIG.

  Even if the engagement between the locking surface 10f of the locking claw portion 10c and the tip 16a of the locked portion 16 is repeated each time the movable beam 4 is repeatedly pulled out to the rear, the impact at this time is not affected by the link mechanism. 20 and the gas cylinder 6 are not affected at all. As a result, deformation or damage of the link mechanism 20 and the gas cylinder 6 over time can be avoided and smooth expansion and contraction of the gas cylinder 6 can be ensured over a long period of time, so that the operator when lifting the movable beam 4 as will be described later. It is possible to improve the reliability for reducing the burden and suppressing the sudden downward rotation of the movable beam 4.

  Further, the movable beam 4 is supported by the guide roller 23 so that the lower surface of the ceiling portion 4a can be advanced and retracted. The guide roller 23 is configured to roll on the upper surfaces of the pair of rail portions 4c. Both the operation of pulling backward from the front end position to the rear end position and the operation of pushing forward from the rear end position to the front end position, that is, the forward and backward operation of the movable beam 4 can be performed smoothly, and the movable beam It is also possible to prevent 4 from falling off the rotating arm 8 and the fixed beam 3.

  When the rear end portion of the movable beam 4 pulled out horizontally is pushed down, as shown in FIG. 8B, the rotating arm 8 supporting the movable beam 4 has the fulcrum pin 7 as the center of rotation. Together with the movable beam 4, it pivots backward and the follower piece 11 pivots counterclockwise, and the gas cylinder 6 is slightly contracted via the link mechanism 20. When the operation of pushing down the rear end of the movable beam 4 is continued, the lower surface of the ceiling portion 8b of the rotating arm 8 is in the inclined posture holding member 17 at the rear end of the gas cylinder housing frame 5 as shown in FIG. In contact with the first elastic body 18 on the inclined posture holding surface 17b, the rotating arm 8 is converted into an inclined posture inclined backward and downward at a predetermined inclination angle, and the movable beam 4 is shown in FIG. Is converted into an inclined posture. Further, as shown in FIG. 8C, the gas cylinder 6 is contracted by the rotation arm 8 being converted into the inclined posture, and resistance to the downward rotation of the movable beam 4 is given via the rotation arm 8. The rapid downward rotation of the movable beam 4 is suppressed. Further, when the lower surface of the ceiling portion 8b of the rotating arm 8 comes into contact with the first elastic body 18 on the inclined posture holding surface 17b by performing a push-down operation so as to convert the movable beam 4 from the horizontal posture to the inclined posture. This shock is absorbed by the first elastic body 18 to be relaxed. Therefore, it is possible to avoid the deformation or damage of the rotating arm 8 and the inclined posture holding surface 17b and eliminate the impact sound.

  When the movable beam 4 is converted into the inclined posture as shown in FIG. 20A, the front wheel of the bicycle B is temporarily placed on the movable beam 4 and pushed up. As a result, when the entire bicycle B is placed on the movable beam 4 as shown in FIG. 20A, the handle 4h is gripped and the rear end of the movable beam 4 is lifted (arrow U), and FIG. Invert to the horizontal position as Following this operation, the rotating arm 8 converted into the inclined posture as shown in FIG. 8 (a) is reversed to the horizontal posture shown in FIG. 8 (a) through the state of FIG. 8 (b), The gas cylinder 6 extends, and the extension force is transmitted to the driven piece 11 at the tip of the rotation arm 8 via the link mechanism 20, and an upward rotation elastic force that rotates the rotation arm 8 rearwardly is generated. Be energized. This upward turning elastic force assists the lifting force of the movable beam 4 supported by the turning arm 8, so that the lifting force of the operator can be reduced and the burden can be reduced. . The reversal behavior of the movable beam 4 is transmitted from the pair of rail portions 4c to the rotating arm 8 without dropping through the guide roller 23, and the rotating arm 8 follows the movable beam 4 from an inclined posture. It can be reversed to a horizontal posture.

  Next, as shown in FIG. 20 (b), if the movable beam 4 inverted to the horizontal posture is pressed (arrow F) and pushed toward the fixed beam 3, then the movable beam 4 as shown in FIG. 20 (d). The bicycle B is parked on the fixed beam 3 via. The forward movement by pushing the movable beam 4 toward the fixed beam 3 is in its initial stage, as shown in FIG. 21A, on the inclined surface 10g of the locking claw portion 10c of the locking lever 10 to be locked. After the rear end 16b of 16 is brought into contact, the movable beam 4 further advances, so that the rear end 16b of the locked portion 16 slides on the inclined surface 10g, as shown in FIG. The locking lever 10 is rotated counterclockwise around the fulcrum pin 9 against the urging force of the elastic body 25, and the locking claw portion 10c is inserted into the lower surface of the ceiling portion 4a of the movable beam 4. Is acceptable.

  As described above, the movable beam 4 is pushed forward by the rear end face 8l of the sandwiching plate 8h (specifically, the front end side 21b of the second elastic body 21) and the abutting plate 15 on the movable beam 4 side. The first stopper mechanism 22 is terminated by the action of restricting the forward movement of the movable beam 4 at the front end position. Specifically, when the abutting plate 15 comes into contact with the distal end side 21b of the second elastic body 21, the pushing of the movable beam 4 forward is completed.

  To take out the bicycle B parked as shown in FIG. 20 (d), the movable beam 4 is pulled out horizontally as shown in FIG. 20 (c), and then converted into an inclined posture as shown in FIG. 20 (b). Can be performed. When the movable beam 4 is converted into the tilted posture, the gas cylinder 6 contracts for the reasons described above to provide resistance to the downward rotation of the movable beam 4 and suppress the sudden downward rotation of the movable beam 4. Further, the impact when the movable beam 4 is converted into the tilted posture is also absorbed and relaxed by the first elastic body 18 for the reason described above.

  The bicycle parking device has a two-stage structure that allows parking on the upper level of the parking space provided on the floor.
