Description

  The present invention relates to a bicycle parking apparatus for enabling a bicycle to be parked in two upper and lower stages.

  Conventionally, a bicycle parking device for parking a bicycle in two upper and lower stages has a groove-shaped fixed beam fixed horizontally at the upper end of an upright post, and a bicycle storage space is secured below the fixed beam. The rail port having a length on which the bicycle can be placed is stored in the fixed beam so as to be movable in the length direction, and the fixed beam is placed at a position at the rear end side where the bicycle is taken in and out of the fixed beam. The rail port that has been pulled out can be rotated to an inclined state where the bicycle can be taken in and out, and in order to store the bicycle, the rail port that has been pulled out for a predetermined length is lowered at the position of the rear end of the fixed beam. By tilting the bike, push the bicycle onto the tilted rail port, enter it, then lift the rail port and rotate it upwards and push the rail port toward the fixed beam in the horizontal position. To accommodate the rolling car.

  Also, when taking out the stored bicycle, contrary to the storage, pull out the rail port to the rear end side of the fixed beam for a predetermined length, then pull down this rail port to make it tilted and take out the bicycle from the rail port. That's fine.

  The bicycle parking device as described above is light when pushing up the rail port on which the bicycle is placed to ensure safety when the rail port is rotated between the inclined state and the horizontal at the rear end side of the fixed beam. When pulling down the rail port, it is necessary to prevent sudden rotation.

  For this reason, an elastic mechanism using a gas cylinder is built into the rail port, and when pushing up the rail port on which the bicycle is mounted, it can be done with a light force by urging the elastic force, and when pulling down the rail port By applying a downward resistance, it is prevented from rotating rapidly (for example, see Patent Document 1).

  The bicycle parking device as described above always has an elongated gas cylinder attached to the lower surface of the front end of the rail port, and supports the lower surface of the rail port in the longitudinal direction at the rear end of the fixed beam. In addition, a stopper that holds the fixed tilt angle of the rail port by engaging and holding the fixed position roller, which is a fulcrum when the rail port is tilted, and the both side movable rollers of the rail port tilted with the fixed position roller as a fulcrum. When the rail port is pulled out rearward, the rod tip of the gas cylinder engages with the mounting shaft of the fixed-position roller, and when the rail port is tilted in this state, the weight of the rail port is applied to the gas cylinder as a load. In addition, by contracting the gas cylinder, resistance is given in the pulling direction, and the rails on both sides of the rail port are engaged with the stopper part by engaging the rail. It will retain the angle of inclination of over preparative constant.

Further, when the rail port is pushed up, an upward rotational elastic force is applied to the rail port by the extension force of the gas cylinder to assist the lifting force.

  By the way, the bicycle parking apparatus as described above can be pushed up with a light force by increasing the elastic force energized when pushing up the rail port, and the downward resistance is increased when lowering the rail port. Therefore, there is a demand for a function that the rail port does not rotate suddenly.

  As a method for satisfying such a demand, it is conceivable to use a gas cylinder that requires a strong force for expansion and contraction and use its elastic force. However, the conventional bicycle parking device described above is attached so as to move integrally with the rail port. Since the gas cylinder is structured to engage and disengage from the fixed shaft mounting shaft, the resistance for contracting the gas cylinder directly acts on the person operating through the rail port, and the force is similar to that of children and women. For weak people, it will be difficult to lower the rail port, and if the elasticity of the gas cylinder is strong, the rail port will rise rapidly when the rail port is pushed up. A problem arises, and for this reason, a gas cylinder that requires a strong force for expansion and contraction cannot be used effectively.

  Therefore, the object of the present invention is to use a gas cylinder that requires a strong force for expansion and contraction, and to increase the elastic force that is energized when pushing up the rail port, so that it can be pushed up with a light force, and the rail port is lowered. In this case, the downward resistance is increased to provide a bicycle parking device in which the rail port does not rotate suddenly.

  In order to solve the above-described problems, the present invention is formed in a groove shape in which a space between guide rails on both sides of the upper part is opened, and has a groove-shaped fixed beam installed horizontally and a length on which a bicycle can be placed. A rail port that is housed in the fixed beam so as to be movable in the length direction, and the rail port is pulled out by a predetermined length at a position on the rear end side of the fixed beam. In the bicycle parking device that can be rotated in an inclined state that can be taken in and out, the lower end of the rail port is supported at the rear end of the fixed beam so as to be movable in the length direction, and A fixed-position roller is provided as a fulcrum for tilting the rail port, and the rail port is attached to the lower surface of the rail port at a tilt angle at which the bicycle can be put in and out of the rail port. A stopper hinge that abuts is fixed, and the rear end of the movable link that can be stored inside the rail port is pivotally connected to the rail port at a position closer to the front end than the stopper hinge. Next, a moving roller that can roll in the length direction along the lower surface of the guide rail is pivoted, and a predetermined rearward position is provided at a position near the rear end side of both guide rails provided on the fixed beam. A structure in which a holding groove into which the moving roller fits is formed with the rail port pulled out at an inclination angle where the bicycle can be taken in and out, and the stopper hinge and the mounting shaft of the moving roller are connected by a gas cylinder. It is.

  The holding grooves provided on the both side guide rails are formed so as to protrude upward in a semicircular arc shape at the upper part of the guide rail so that the moving rollers are fitted, and the moving rollers are fitted into the holding grooves, and When the stopper hinge is in contact with the fixed position roller and the rail port is at an inclination angle where the bicycle can be taken in and out, it is flush with the horizontal line passing through the upper surface of the fixed position roller and the axis of the mounting shaft of the moving roller. The cylinder may have a structure in which the shaft center is inclined with respect to a horizontal line passing through the shaft center of the mounting shaft of the moving roller so that the shaft center is lowered toward the pivot point to the stopper hinge.

  The relationship between the holding groove into which the moving roller is fitted and the lower surface of the guide rail is such that the lower surface of the guide rail is positioned below the horizontal line passing through the axis of the moving roller with the moving roller fitted into the holding groove. The contact between the inner circumference of the holding groove and the lower surface of the guide rail is a holding point for preventing the moving roller fitted in the holding groove from moving toward the distal end side of the fixed beam. Can do.

  According to this invention, the fixed-position roller serving as a fulcrum when the lower end of the rail port is supported and tilted at the rear end of the fixed beam is provided, and the rear end of the movable link that can be stored inside the rail port is provided. It is pivotally connected to the lower surface of the rail port near the tip, and a moving roller that can roll in the length direction along the lower surface of the guide rail along the lower surface of the guide rail is pivoted on the mounting shaft. A holding groove into which the moving roller fits in a state where the rail port is pulled out rearward by a predetermined length is formed at a position near the rear end side of the both side guide rails provided on the fixed beam, and is movable on the lower surface of the rail port. The position closer to the rear end of the link pivot position and the moving roller mounting shaft of the movable link are connected by the gas cylinder, so the movable link and the gas cylinder move together with the rail port, and when the rail port tilts The gas cylinder is contracted by the change of the angle of the moving link, and when the rail port is pushed up to the horizontal state, the gas cylinder is extended by the change of the angle of the movable link. Using a gas cylinder that is strong against expansion and contraction, and increasing the elastic force that is energized when pushing up the rail port, it can be pushed up with a light force. When pulling down, the downward resistance can be increased so that the rail port does not rotate suddenly.

  In addition, when the moving roller fits into the holding groove and the stopper hinge abuts the fixed position roller and the rail port is at an inclination angle at which the bicycle can be taken in and out, the upper surface of the fixed position roller and the mounting shaft of the moving roller The horizontal line passing through the shaft center is at the same height, and the gas cylinder is inclined so that the shaft center is lowered toward the stop point to the stopper hinge with respect to the horizontal line passing through the shaft center of the mounting shaft of the moving roller. Therefore, the tilt angle of the rail port where the bicycle can be put in and out can be maintained by the triangular structure of the rail port, the movable link and the gas cylinder, and the contraction force of the contracted gas cylinder acts on the rail port angle maintenance. The tilting posture of the rail port where the bicycle can be taken in and out is stable without flickering up and down.

  Furthermore, the contact point between the inner periphery of the holding groove and the lower surface of the guide rail serves as a holding point for preventing the moving roller fitted in the holding groove from moving toward the tip side of the fixed beam. The tilting posture of the port where the bicycle can be taken in and out can be maintained even in the holding groove portion.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIGS. 1, 2, and 8, a bicycle parking device 1 for parking a bicycle A in two upper and lower stages is provided with a groove-shaped fixed beam 4 on an upper end horizontal shaft 3 of a post 2 erected on the ground. The rail port 6 that is fixed horizontally and secures a bicycle storage space at the lower portion of the fixed beam 4 to provide a lower bicycle storage base 5 and on which the bicycle A can be placed is provided in the fixed beam 4. The rail port 6 pulled out by a predetermined length is inclined so that the bicycle A can be taken in and out at a position on the rear end side where the bicycle A is taken in and out of the fixed beam 4. It can be rotated.

  Here, in the front and rear of the bicycle parking device 1, the post 2 side where the front wheel of the bicycle A is located is the front end side, and the side where the bicycle is taken in and out is the rear end side.

  As shown in FIG. 4, the fixed beam 4 is formed in a groove shape that opens between the guide rails 7 on both sides of the upper part, has a slightly shorter front-rear length than the bicycle A, and has a tip on the side 3 of the post 2. The part is fixed.

  The fixed beam 4 is supported at a position on the rear end side where the bicycle is taken in and out so that the lower surface of the rail port 6 can be moved in the length direction, and a fixed point serving as a fulcrum when the rail port 6 is tilted. A position roller 8 is provided.

  The rail port 6 has a cylindrical shape with an open bottom surface that holds the fixed-position roller 8 and has a U-shaped cross-section with the tip side facing downward, and a width that can fit between the guide rails 7 of the fixed beam 4 and a length on which the bicycle A can be placed. The wheel guide frames 9 are provided opposite to each other at the upper part of each side, the lower surface is supported by the fixed position roller 8 and can move in the length direction, and the fixed position roller 8 is connected to the rail port 6. Is a fulcrum when tilting is moved at the rear end of the fixed beam 4.

  A movable link 10 formed as a short link with a U-shaped cross-section facing downward is disposed inside the front end side of the rail port 6, and the rear end of the movable link 10 is pivoted to the lower surface side near the front end of the rail port 6. A movable roller 12 is attached to both ends of the movable link 10 so as to be able to roll in the length direction of the fixed beam 4 along the lower surface of the guide rail 7 while being accommodated in the fixed beam 4. The shaft 13 is pivoted.

  The movable link 10 moves integrally with the rail port 6 by the connection at the pivot 11, and the rail port 6 and the movable link 10 can be bent at the portion of the pivot 11, and the moving roller 12 of the movable link 10 is moved during the movement. By rolling the lower surfaces of both guide rails 7, the guide rails 7 are prevented from coming out of the fixed beam 4.

  In a state where the rail port 6 is at a position slightly closer to the rear end than the pivot point of the movable member 10 on the lower surface of the rail port 6 and at a predetermined inclination angle at which the bicycle can be taken in and out, the rail is fixed to the fixed position roller 8. A stopper hinge 14 that abuts the port 6 in the retaining direction is fixed, and the stopper hinge 14 and the mounting shaft 13 of the moving roller 12 are pivotally connected by a gas cylinder 15. The stopper hinge 14 and the rod of the gas cylinder 15 are pinned. 16 are combined.

  The rail port 6 is pulled backward by a predetermined length at a position near the rear end of the guide rails 7 on both sides of the fixed beam 4 and the gas cylinder 15 is contracted so that the rail port 6 can be inserted into and removed from the bicycle A by a predetermined inclination. A holding groove 17 into which the moving roller 12 is fitted in an angled state is provided, and the holding groove 17 is formed on the upper portion of the guide rail 7 so as to protrude upward in a semicircular arc shape.

  As shown in FIG. 7, when the moving roller 12 is fitted in the holding groove 17 and the stopper hinge 14 is in contact with the fixed position roller 8 and the rail port 6 is at an inclination angle at which the bicycle A can be inserted and removed, The upper surface of the position roller 8 and the horizontal line passing through the axis of the mounting shaft 13 of the moving roller 12 are at the same height. In this state, the gas cylinder 15 is in relation to the horizontal line passing through the axis of the mounting shaft 13 of the moving roller 12. The axis of the lever is inclined so as to descend toward the stop point to the stopper hinge 14.

  Further, the relationship between the holding groove 17 into which the moving roller 12 is fitted and the lower surface of the guide rail 7 is such that the guide rail is more than the horizontal line passing through the axis of the moving roller 12 with the moving roller 12 fitted into the holding groove 17. The lower surface of 7 is positioned slightly below, and the contact roller between the inner periphery of the holding groove 17 and the lower surface of the guide rail 7 is moved toward the distal end side of the fixed beam 4 by the moving roller 12 fitted in the holding groove 17. This is a holding point 18 for preventing this.

  A noise-reducing cushion 19 is attached to the upper surface of the movable link 10 so as not to generate noise when overlapping with the rail port 6, and the moving roller 12 is horizontally placed on both sides of the front end of the rail port 6. A notch 20 is provided to be fitted around the mounting shaft 13.

  The bicycle parking apparatus of the present invention is configured as described above, and in order to start storing the bicycle A, the rail port 6 pulled out by a predetermined length at the position of the rear end side where the bicycle of the fixed beam 4 is taken in and out is provided. The bicycle A is turned to an inclined state where the bicycle A can be taken in and out.

  When the rail port 6 is in the horizontal state, as shown in FIG. 3, the movable link 10 is stored in the horizontal state inside the rail port 6, and the rail port 6 is composed of the fixed position roller 8 and the moving roller 12 of the movable link 10. The gas cylinder 15 is extended by being supported within the fixed beam 4.

  When the rail port 6 is pulled out rearward in this state, first, as shown in FIG. 6, the stopper hinge 14 comes into contact with the fixed position roller 8 to stop pulling out the rail port 6, and then the rear end of the rail port 6 is stopped. Is pushed down, the rail port 6 rotates about the fixed position roller 8 with which the stopper hinge 14 abuts, and the connecting pivot 11 of the movable link 10 with respect to the rail port 6 rotates upward about the fulcrum. Therefore, the movable link 10 is lifted on the rear end side with the mounting shaft 13 of the front-side moving roller 12 in contact with the lower surface of the guide rail 7 as a fulcrum, so that the front end side of the movable link 10 approaches the rail port 6. Therefore, the gas cylinder 15 is compressed, and the resistance elasticity generated by the compression of the gas cylinder 15 is the rail port 6. Becomes braking force when rotated downward, rail port 6 can be prevented from being rapidly dropped.

  When the rail port 6 rotated downward has a predetermined inclination angle, it fits into the moving roller 12 provided on the distal end side of the movable link 10 or the holding groove 17 of the guide rails 7 on both sides. It is held at a predetermined inclination angle.

  As shown in FIG. 7, in a state where the rail port 6 is held at a predetermined inclination angle, the gas cylinder 15 is disposed between the stopper hinge 14 contacting the fixed position roller 8 and the moving roller 12 fitted in the holding groove 17. The movable link 10 is stretched in a contracted state and accumulated with an extension force, and the movable link 10 is located between the distal end side of the rail port 6 and the moving roller 12 fitted in the holding groove 17, and the upper distal end side of the stopper hinge 14 of the rail port 6. Thus, the gas cylinder 15, the movable link 10, and a part of the rail port 6 have a triangular positional relationship, and the rail port 6 having a predetermined inclination angle is held in a stable state without flickering. Can do.

  When the moving roller 12 is fitted in the holding groove 17 and the stopper hinge 14 is in contact with the fixed position roller 8 and the rail port 6 is at an inclination angle that allows the bicycle A to be taken in and out, the upper surface of the fixed position roller 8 is The horizontal line passing through the axis of the mounting shaft 13 of the moving roller 12 is at the same height, and the gas cylinder 15 has its axis extending to the stopper hinge 14 with respect to the horizontal line passing through the axis of the mounting shaft 13 of the moving roller 12. Since the tilting force of the contracted gas cylinder 15 acts as the angle holding force of the rail port 6, the tilting posture of the rail port 6 in which the bicycle A can be taken in and out is stable. To do.

  Further, the contact point between the inner periphery of the holding groove 17 and the lower surface of the guide rail 7 serves as a holding point 18 for preventing the moving roller 12 fitted in the holding groove 17 from moving toward the distal end side of the fixed beam 4. As a result, the stability of the tilted posture in which the bicycle A of the rail port 6 can be taken in and out can be maintained even in the holding groove 17 portion.

  As described above, with the rail port 6 held at a predetermined inclination angle, as shown in FIG. 8 (a), the bicycle A is pushed up onto the rail port 6 and entered, as shown in FIG. 8 (b). When the entire bicycle A is placed on the rail port 6, the rear end side of the rail port 6 is lifted as indicated by an arrow x in the figure.

  When the rail port 6 is lifted, the rail port 6 rotates about the fixed position roller 8 with which the stopper hinge 14 abuts, and the movable link 10 connected to the rail port 6 is pushed toward the tip side. The moving roller 12 is detached from the holding groove 17 and at the same time the gas cylinder 15 is extended to push the tip of the movable link 10, thereby providing the rail port 6 with a downward elasticity in the horizontal direction, thereby increasing the lifting force. Assist and lift the rail port 6 on which the weight of the bicycle A is applied with a light force to be in a horizontal state as shown in FIG.

  When the rail port 6 becomes horizontal, as shown in FIG. 3, the gas cylinder 15 is fully extended, and the movable link 10 is accommodated in the rail port 6 in a horizontal state. The rail port 6 includes the fixed position roller 8 and the movable link. Since it is supported horizontally by the 10 moving rollers 12 and fits in the fixed beam 4, if the rail port 6 is pushed toward the fixed beam 4, the bicycle A is stored on the fixed beam 4 as shown in FIG. It becomes a state.

  The rail port 6 pushed toward the fixed beam 4 is held by fitting a fixing groove 21 provided near the rear end on the bottom surface of the rail port 6 on the fixed position roller 8.

  Further, the movable link 10 and the gas cylinder 15 move integrally with the rail port 6, the gas cylinder 15 is contracted by the change in the angle of the movable link 10 when the rail port 6 is tilted, and the rail port 6 is brought into a horizontal state. At the time of pushing up, the gas cylinder 15 is extended by changing the angle of the movable link 10, and the gas cylinder 15 can be expanded and contracted without requiring a large force. Therefore, the gas cylinder 15 having a strong force for expansion and contraction is used. Thus, when the rail port 6 is pushed up, the elastic force to be urged is increased so that the force can be pushed up with a light force. When the rail port 6 is pulled down, the downward resistance is increased and the rail port 6 is suddenly pushed up. Can be prevented from rotating.
