Description

  The present invention relates to a bicycle three-dimensional bicycle parking apparatus that can park a bicycle efficiently on land of a limited area by parking the bicycle in two upper and lower stages.

  In recent years, two-level bicycle multi-level bicycle parking devices that can efficiently park bicycles on a limited area have been developed, and these bicycle multi-level bicycle parking devices have been developed around stations and shopping streets. It is effective for the problem of annoying bicycle parking in public places and the problem of securing a bicycle parking space in apartment houses such as apartments and apartments.

  As such a bicycle three-dimensional bicycle parking device, for example, the upper part of the frame developed by the present applicant, which is fixed substantially horizontally on the upper part of a frame having a predetermined height or a horizontal beam horizontally installed on the supporting pillar, has an upper part. A fixed guide rail composed of an open groove shape or lip groove shape steel, and a groove shape or hat in which a bicycle is placed and an upper portion that is movably inserted into the fixed guide rail is open The fixed guide rail has a support roller for pivotally supporting the lower surface of the movable guide rail at the front end, and the movable guide rail horizontally. A substantially horizontal horizontal portion having a predetermined length to be moved to the front, and a curved portion for inclining that has a curved shape extending continuously from the front portion of the horizontal portion to the upper portion of the fixed guide rail. A guide member for guiding the outer surface of the movable guide rail is fixed to the inner surface of the fixed guide rail on the front end side of the curved portion for tilting of the guide member of the fixed guide rail. Further, an engaging roller that engages with the guide member is pivotally attached to the outer surface of the rear end portion of the movable guide rail, and when the engaging roller and the tilting curved portion of the guide member are engaged with each other. A lift prevention member that is positioned immediately below the shake prevention guide and prevents the movable guide rail from lifting is provided, and an engagement roller is locked to the front end of the tilting curved portion of the guide member. There is a bicycle multi-story parking apparatus (see, for example, Patent Document 1) provided with a stopper.

  However, in such a bicycle multi-story parking device, although a bicycle can be parked efficiently on a land of a limited area, when the bicycle is carried into the upper stage, a movable guide stored in a fixed guide rail. Since the bicycle is placed on the movable guide rail with the rail pulled out and tilted, the bicycle is lifted upward and stored in the fixed guide rail. Therefore, the movable guide rail is made of a section steel as described above. Not only is it heavy, but it also requires a lot of work because the bicycle must be lifted up and stored in the fixed guide rail while it is placed on this heavy movable guide rail. When the bicycle placed on the upper stage is carried out, the movable guide rail with the bicycle placed thereon is fixed to the fixed guide rail. Although it is pulled out from the inside and tilted, the weight of the movable rail with the bicycle placed thereon is large as described above, and it is necessary to tilt while supporting this large weight by hand, especially for children and women. There was also a problem that a great deal of labor was required.

  Therefore, in order to overcome such a problem, for example, the upper part of the frame developed by the present applicant, which is fixed substantially horizontally on the upper part of a frame made up of a pillar having a predetermined height or a transverse beam laid on the pillar, is A fixed guide rail made of a steel having a groove shape or a lip groove shape, and a groove shape having an open upper portion on which a bicycle is placed and movably inserted into the fixed guide rail A substantially horizontal horizontal guide portion having a predetermined length for guiding and moving the movable guide rail in a substantially horizontal direction, and a horizontal guide portion of the horizontal guide portion. A guide member composed of a tilting guide portion that is continuous with the front portion and guides the front end of the movable guide rail drawn out toward the front so as to tilt downward is fixed to the inner surface of the fixed guide rail. An engagement roller that engages with the guide member is pivotally attached to the outer surface of the rear end portion of the movable guide rail, and the engagement roller is attached to the front end portion of the guide portion for tilting the guide member. A bicycle three-dimensional bicycle parking device provided with a stopper for locking, and a support roller for supporting the movable guide rail is pivotally attached to the front end portion in the fixed guide rail, and the piston rod is pushed in the direction in which it is pushed. A shock absorber with a substantially constant reaction force against the displacement, the piston rod protrudes most when the movable guide rail is pulled out and the engagement roller moves near the front end of the horizontal guide portion of the guide member. In this state, the engaging portion provided on the piston rod or cylinder on the rear end side of the shock absorber is engaged with the engaging portion provided on the movable guide rail so as to be integrated with the movable guide rail. It is arranged so that it can rotate around its front end at the front end in the fixed guide rail, and the guide member for tilting the guide member is connected to the movable guide rail from the contact point with the movable guide rail. Bicycle three-dimensional parking devices (see, for example, Patent Document 2) and the like that are formed in a shape that gradually decreases as the distance goes to the front end have been proposed.

  In such a bicycle three-dimensional parking device, not only can the movable guide rail be prevented from abruptly tilting by the shock absorber acting on the displacement in the direction in which the piston rod is pushed, but also to the upper stage of the bicycle. Can be carried out easily and safely without applying a large force, but the movable guide rail is guided to move substantially horizontally and the front end of the movable guide rail pulled out to the front is tilted downward. The guide member for carrying out is a complicated shape having a long length in the longitudinal direction and a front portion bent upward and having a U-shaped cross section over the entire length. When the member is fixed to both inner surfaces of the groove-shaped or lip-grooved shape steel having an open top, the movable guide rail and the movable guide rail are placed on this guide member. The upper edge side of the guide member and the inner surface side of the shape steel are in contact with each other and under the guide member so that the guide member does not come off from the inner side of the shape steel even if an upward or downward load is applied by the bicycle. The part where the edge side and the inner surface side of the structural steel are in contact with each other must be securely fixed by welding or the like over the entire length in the longitudinal direction of the guide member. Since it is fixed in a very narrow space, the manufacturing process is very complicated and the number of steps is large.

  In this bicycle three-dimensional parking device, the fixed guide rail has a long shape in the longitudinal direction as described above, and its front is bent upward and has a complicated shape with a U-shaped cross section over the entire length. A pair of guide members capable of withstanding an upward or downward load by a bicycle mounted on the movable guide rail and the movable guide rail, and the pair of guide members are securely fixed to both inner surfaces in the longitudinal direction. Since it is composed of two members, a groove-shaped or lip-grooved shape steel having an open upper portion having a size and rigidity capable of being fixed, the material cost of the fixed guide rail itself is high and its There is also a drawback that the weight is very heavy and the size is large, and the weight of the fixed guide rail is very heavy. As described above, the manufacturing process is very complicated and the man-hours are large, and the material of each member is also required. Since the cost is high, there is a drawback that the manufacturing cost of the entire apparatus is very high.

  Furthermore, in this bicycle three-dimensional bicycle parking apparatus, the fixed guide rail itself is very heavy and large in size as described above, and from a horizontal beam that is installed horizontally on a column or column that supports the fixed guide rail substantially horizontally. Since the resulting frame becomes very heavy, not only is the workability when installing the apparatus poor, but the transportation cost is also high.

Utility Model Registration No. 2537425 Japanese Patent No. 3445137

  The present invention solves the problems of the prior art, can not only prevent a sudden tilt of the movable guide rail, it can be carried out easily and safely without applying a large force to the upper stage of the bicycle, It is another object of the present invention to provide a bicycle three-dimensional bicycle parking apparatus that is small and light and that is inexpensive to manufacture.

  As a result of diligent research to solve the above problems, the present inventor first examined a mechanism for moving the engaging roller of the movable guide rail substantially horizontally and pulling the movable guide rail forward. A lip having an opening at the top and a groove formed on the front side at a predetermined position in front of the upper part, and a rear part where the engaging roller is guided and moved substantially horizontally is slightly larger than the diameter of the engaging roller. If the shape steel formed in the groove shape is adopted, the movable guide rail engaging roller is fixed directly to the fixed guide rail without fixing the member for guiding and moving the movable guide rail substantially horizontally. Since the bottom and bottom surfaces of the shape steel lip can be guided and moved substantially horizontally, the fixed guide rails can be integrated into one member. It was.

  Then, after examining a mechanism for guiding the front end of the movable guide rail pulled out further forward so as to tilt downward, the movable guide rail is supported by a support roller pivotally attached to the front end portion of the fixed guide rail. When the movable guide rail is pulled forward, the center of gravity of the movable guide rail is engaged with the support roller at the initial position where the engagement roller of the movable guide rail is located on the rear end side of the fixed guide rail. Since it is located on the side of the combined roller, a force to move downward is applied to the engagement roller, and if the movable guide rail is pulled forward until the center of gravity of the movable guide rail is located on the front side of the support roller, A force to move upward is applied to the engaging roller with the roller as a fulcrum, and the force to move the engaging roller upward is As the distance between the support roller and the engagement roller becomes shorter as the drag is pulled forward, it becomes stronger, so the movable guide rail pulled forward engages the shock absorber and lowers its front end. When guided to tilt, the force to rotate the support roller by the dead weight of the movable guide rail and further shift to the front end side is canceled out by the reaction force of the shock absorber. Focusing on the fact that only a strong force to move the engaging roller of the part upward acts, as a member for guiding the front end of the movable guide rail to tilt downward, it is continuous with the front end of the lip of the fixed guide rail and If an inclined guide member that restricts the movement of the engagement roller only from the upper side is adopted, the upper part is open as described above, and the front side is a groove shape at a predetermined position in front of the upper part. And a fixed guide rail made of a steel plate having a lip groove shape in which a rear side portion where the engaging roller is guided and moved substantially horizontally is slightly larger than the diameter of the engaging roller. There is no need to use a guide member having a long shape in the longitudinal direction such as a device and having a complicated shape having a U-shaped cross section over its entire length. The present invention was completed by investigating that the manufacturing cost can be reduced.

That is, the present invention consists of a groove-shaped, lip-grooved or hat-shaped shaped steel with an open top, and a pair of engagements so that the rear end is located at a position protruding from both webs of the shaped steel. A movable guide rail on which a bicycle is placed from the front side, with a roller pivotally attached and engaging means projecting below the rear end,
The frame is fixed to a column having a predetermined height or an upper part of a frame made of a cross beam horizontally provided on the column, and is fixed substantially horizontally toward the front. The groove shape is made of a steel plate formed in a lip groove shape in which the distance between the lower surface of the lip and the bottom surface of the lip is slightly larger than the diameter of the engaging roller, and the movable guide rail is formed at the front end portion thereof. A support roller that is movably supported, and a fixed guide rail that guides and moves the engaging roller of the movable guide rail substantially horizontally between the lower surface of the lip and the bottom surface of the section steel;
Supporting the fixed guide rail as the engaging roller of the movable guide rail moves to the front end side when the front end of the movable guide rail drawn forward is continuous with the front end of the lip of the fixed guide rail. An inclined guide piece that guides and moves so that the distance from the contact point between the roller and the movable guide rail to the axis of the engaging roller of the movable guide rail gradually decreases, and the front end of the movable guide rail tilts downward most. In this case, a locking piece is formed to hold the movable guide rail in an inclined state by locking the engaging roller, and both webs extending from a predetermined position in front of the fixed guide rail to the front end portion are formed. A pair of inclined guide members fixed respectively;
When the piston rod is pushed into the cylinder, a substantially constant reaction force acts on the displacement in the direction in which the piston rod is pushed, and the front end of the piston rod or the rear end of the cylinder is the front end of the fixed guide rail. A shock absorber supported on the shock absorber, and a piston of the shock absorber when the engaging roller of the movable guide rail is pulled forward to the vicinity of the front end of the lip of the fixed guide rail. An engaging means that engages with the engaging means of the movable guide rail with the rod protruding most, and the shock absorber is integrated with the movable guide rail when tilted downward of the front end of the movable guide rail. A buffer mechanism that rotates around the front end of the fixed guide rail,
This is a bicycle three-dimensional bicycle parking device characterized by comprising:

  And in such a bicycle three-dimensional parking device according to the present invention, if the roller shafts of the pair of engaging rollers of the movable guide rail are pivotally mounted so as to be positioned below the back surface of the bottom surface of the shape steel, It is preferable that the height of the fixed guide rail can be minimized, and the engaging means of the movable guide rail and the engaged means of the buffer mechanism are arranged so that the movable guide rail is pulled forward and the movable guide rail If the engaging roller is arranged so as to engage when it comes into contact with the rear end of the tilt guide piece of the tilt guide member, the operation when the front end of the movable guide rail drawn forward is tilted downward is performed. They also found out that it can be smooth and preferable.

  Further, if the shock absorber of the buffer mechanism is pivotally attached to the roller shaft of the support roller of the fixed guide rail, the movable guide rail is engaged with the engaged means of the buffer mechanism and the movable guide rail is engaged. The piston rod of the shock absorber shock absorber when the movable guide rail and the shock absorber mechanism are integrally formed and rotated around the front end of the fixed guide rail when the front end of the shock absorber is tilted downward. It has also been found that it is preferable that the reaction force required for the shock absorber can be further reduced since the movement direction of the first and second movements can be made substantially parallel to the longitudinal direction of the movable guide rail.

  Furthermore, the sound guide members made of an elastic body are fixed to the inner surface sides of the both inclined guide members so as to face each other with a slight space between the outer surfaces of the movable guide rails, and the movable guide rails. If a pair of leaf springs that slightly protrude in the direction of the respective silencing members are fixed to the movable guide rails at positions facing the silencing members when positioned at the rearmost side, the movable guide rails are fixed. When storing on the guide rail, it is also possible to prevent the collision noise from being generated due to the collision of the engaging roller of the movable guide rail with the rear end side of the fixed guide rail. It was.

  The bicycle three-dimensional parking apparatus according to the present invention has an opening at the top, a groove shape on the front side and a distance on the back side between the lower surface of the lip and the bottom surface of the movable guide rail. Both webs extending from a predetermined position in front of the fixed guide rail to the front end portion of a fixed guide rail made of a shape steel formed in the shape of a lip groove slightly larger than the diameter of the engaging roller pivotally attached to protrude at the rear end portion When the front end of the movable guide rail, which is continuous with the front end of the lip of the fixed guide rail and tilts downward, tilts downward, the movable roller of the movable guide rail moves with the support roller of the fixed guide rail as the front end moves. A pair of inclined guide members formed with an inclined guide piece for guiding and moving so that the distance from the contact point with the guide rail to the axis of the engaging roller of the movable guide rail gradually decreases. The fixed guide rail can be integrated into one member, and the length in the longitudinal direction is long and the front is bent upward as in the conventional device. Since there is no need to use a guide member having a complicated shape that is U-shaped, the fixed guide rail can be reduced in size and weight and the material cost can be reduced, and the weight of the fixed guide rail itself can be reduced. Since it is light, it is possible to use a relatively inexpensive material that is not high in rigidity as a steel material used for a frame made up of a column that supports the fixed guide rail and the like and a horizontal beam that is installed on the column. The entire apparatus can be made small and light, and the material cost can be made very low.

  And the bicycle three-dimensional bicycle parking apparatus according to the present invention can make the material cost very low as compared with the conventional apparatus, and further, the fixed guide rail is connected to the upper edge side of the guide member as in the conventional apparatus. It is necessary to securely weld and fix the part where the inner side of the shape steel is in contact and the part where the lower edge side of the guide member and the inner side of the shape steel are in contact over the entire length in the longitudinal direction of the guide member. Since the manufacturing process can be simplified, the manufacturing cost of the entire device can be made as low as possible, and the entire device can be made smaller and lighter than conventional devices. Therefore, not only can the workability at the time of installation work be improved, but also the transportation cost can be reduced.

  And in such a bicycle three-dimensional parking device according to the present invention, if the roller shafts of the pair of engaging rollers of the movable guide rail are pivotally mounted so as to be positioned below the back surface of the bottom surface of the shape steel, Since it is possible to use an engagement roller with a small diameter that can secure a space for disposing a buffer mechanism between the bottom surface of the movable guide rail and the bottom surface of the fixed guide rail, the height of the fixed guide rail can be reduced. As the fixed guide rail can be used as the fixed guide rail, and the bottom surface of the fixed guide rail can be adopted from the front end side to the rear end side. Therefore, the fixed guide rail can be further reduced in size and weight. The material cost can also be reduced, which is preferable.

  Further, the engaging means of the movable guide rail and the engaged means of the buffer mechanism are such that the movable guide rail is pulled forward and the engaging roller of the movable guide rail contacts the rear end of the inclined guide piece of the inclined guide member. If the front end of the movable guide rail drawn forward is tilted downward, the movable guide rail engaging means and the buffered mechanism engaging means are engaged with each other. Therefore, not only can the operation when the front end of the movable guide rail tilts downward be smooth, which is preferable, but also the force required for the operation when the front end of the movable guide rail tilts downward is reduced. Is preferable.

  Further, if the shock absorber of the buffer mechanism is pivotally attached to the roller shaft of the support roller of the fixed guide rail, the engaging means of the movable guide rail and the engaged means of the buffer mechanism are engaged, and the movable guide rail The piston rod of the shock absorber shock absorber when the movable guide rail and the shock absorber mechanism are integrally formed and rotated around the front end of the fixed guide rail when the front end of the shock absorber is tilted downward. Can be made substantially parallel to the longitudinal direction of the movable guide rail, so that the reaction force required for the shock absorber can be made smaller, which is preferable. Since the container is pivotally attached to the same shaft, the number of parts can be reduced, which is preferable.

  Furthermore, the sound guide members made of an elastic body are fixed to the inner surface sides of the both inclined guide members so as to face each other with a slight gap between the outer surfaces of the movable guide rails. If a pair of leaf springs that slightly protrude in the direction of the respective silencing members are fixed to the movable guide rails at positions facing the silencing members when positioned at the rearmost side, the movable guide rails are fixed guides. When storing on the rail, not only is it preferable that the engagement roller of the movable guide rail collides with the rear end side of the fixed guide rail vigorously, so that a collision noise can be prevented. When moving the movable guide rail, it can be prevented that the movable guide rail swings to the left or right. Preferably it is able to perform move stably the.

Hereinafter, the bicycle three-dimensional parking device according to the present invention will be described in detail with reference to the drawings.

  In the drawing, reference numeral 1 is a shape of a steel shape 1a having a groove shape, a lip groove shape, or a hat shape with an open top, and a pair of engagements are located at positions where the rear ends protrude from both webs of the shape steel 1a. The combined rollers 1b and 1b are pivotally attached, and the engaging means 1c is provided below the rear end portion, and is a movable guide rail on which the bicycle is placed from the front side. The bicycle is placed in a state where it is drawn forward from 2 and tilted, and the bicycle is lifted upward in a state where the bicycle is placed, and is stored in a fixed guide rail 2 described later.

  The section 1a of the movable guide rail 1 is particularly suitable if it is made of a section having a groove shape, a lip groove shape or a hat shape with an open top so that the bicycle can be placed with the wheel inserted. Although not limited, as shown in FIGS. 1 and 4, wheel guide members for stably placing the bicycle are provided on both side edges of the open portion of the top surface of the shape steel 1a, or movable guides. It is preferable that an operation handle for facilitating an operation such as pulling out the rail 1 from a fixed guide rail 2 to be described later is provided to protrude forward at the front end portion of the section steel 1a.

  The engaging rollers 1b of the movable guide rail 1 are located at positions projecting from both webs of the section steel 1a, that is, positions projecting from both side surfaces of the section steel 1a when the section steel 1a is viewed from below. The pair of pivots are attached to each other, and the distance between the lower surface of the rear lip 2aa of the shape steel 2a of the fixed guide rail 2 described later and the surface of the bottom surface thereof is slightly larger than the diameter of the engaging roller 1b. The groove-shaped portion is guided and moved substantially horizontally by the lower surface of the lip 2aa and the bottom surface of the shaped steel 2a, and is moved only from above by a pair of inclined guide members 3 and 3 which are described later. By restricting, the front end of the movable guide rail 1 is guided and moved so as to tilt downward.

  As the engaging roller 1b of the movable guide rail 1, a pair of pivot rollers are mounted so as to be located at positions protruding from both webs of at least the section steel 1a, and at least when the movable guide rail 1 is pulled out substantially horizontally. The bottom surface of the section steel 1a of the movable guide rail 1 collides with a buffer mechanism 4 described later or projects below the rear end of the movable guide rail 1 so that the engaging means 1c has a section steel 2a of the fixed guide rail 2 described later. The rear side of the section 2a of the fixed guide rail 2 is guided substantially horizontally between the lower surface of the lip 2aa of the section 2a of the fixed guide rail 2 and the bottom surface of the section 2a so as not to interfere with the bottom surface of the section. For example, although not shown, the roller shaft is directly pivotally attached to both webs of the movable guide rail 1 as the engaging roller 1b of the movable guide rail 1, and the lower end of the bottom surface of the bottom surface of the movable guide rail. A roller having a large diameter that is positioned below the height of the shock absorbing mechanism 4 is used, and the lower surface of the lip 2aa on the rear end side of the structural steel 2a and the bottom surface of the structural steel 2a are used as the fixed guide rail 2. The roller shaft is slightly larger than the diameter of such a roller, or although not shown, the roller shaft is directly applied to both webs of the movable guide rail 1 as the engaging roller 1b of the movable guide rail 1. A fixed guide rail 2 is used that is pivotally mounted and has a relatively small diameter such that the lower end of the movable guide rail 1 is positioned below the rear surface of the bottom surface of the section 1a of the movable guide rail 1 by the amount of the engaging means 1c. For example, it is possible to use a member in which a recess is further formed from the front end of the shape steel 2a to the rear bottom surface so as to accommodate the lower side of the engagement mechanism 4b of the buffer mechanism 4.

  Then, the engaging roller 1b of the movable guide rail 1 has the roller shafts of the movable guide rail 1 having a bottom surface of the bottom surface of the section steel 1a as shown in FIG. 2, FIG. 3, FIG. If it is pivotally mounted so as to be positioned below, the engagement with a small diameter that can secure a space for disposing the buffer mechanism 4 between the bottom surface of the movable guide rail 1 and the bottom surface of the fixed guide rail 2. Since the roller 1b can be used, the height of the fixed guide rail 2 can be minimized, and a convex portion or the like is further formed from the front end of the shape steel 2a of the fixed guide rail 2 to the bottom of the rear. This is preferable because the fixed guide rail 2 can be made as small and thin as possible and the material cost can be reduced.

  Below the rear end of the section steel 1a of the movable guide rail 1, as shown in FIGS. 2, 3, 5, 6 and 7, an engaging means 1c is projected, and this engaging means 1 to 3, a shock absorber of a buffer mechanism 4 to be described later when the engaging roller 1 b of the movable guide rail 1 is drawn forward to the vicinity of the front end of the lip 2 aa of the fixed guide rail 2 to be described later. FIG. 4 and FIG. 5 show that the piston rod 4aa of 4a is engaged with an engaged means 4b of the buffer mechanism 4 to be described later and engaged with an engaged means 4b of the buffer mechanism 4 with the piston rod 4aa protruding most. Thus, when the front end of the movable guide rail 1 is tilted downward, the shock absorber 4a and the movable guide rail 1 form an integral body and rotate around the front end of the fixed guide rail 2.

  The engaging means 1c of the movable guide rail 1 may have any shape as long as it can be engaged with an engaged means 4b of the buffer mechanism 4 to be described later. For example, FIG. 2, FIG. 3 and FIGS. As shown in FIG. 4, the front end of the movable guide rail 1 is protruded from the bottom of the section steel 1a of the movable guide rail 1 at a predetermined interval in the width direction. Examples that can be combined are exemplified.

To 3a It guides you to guide the regulation.

  As a shape steel 2a of the fixed guide rail 2, the distance between the lower surface of the lip 2aa and the bottom surface of the lip 2aa is the engagement roller of the movable guide rail 1, and the front side is a groove shape with a predetermined front position as a boundary. It is formed in a lip groove shape slightly larger than the diameter of 1b, and at least when the movable guide rail 1 is pulled out substantially horizontally, the bottom surface of the section steel 1a of the movable guide rail 1 collides with a buffer mechanism 4 described later. Or the lower surface of the lip 2aa and the surface of the bottom surface thereof so that the engaging means 1c does not interfere with the bottom surface of the section steel 2a of the fixed guide rail 2 described later. As long as the engaging roller 1b of the movable guide rail 1 can be guided and moved substantially horizontally, the engaging roller 1b of the movable guide rail 1 is connected to both the movable guide rails 1 (not shown). In the case where the roller shaft is pivotally attached directly to the Eb, and the lower end of the roller is a roller having a large diameter so as to be positioned below the back surface of the bottom surface of the shape steel of the movable guide rail 1 by the height of the buffer mechanism 4. If the distance between the lower surface of the lip 2aa on the rear end side of the structural steel 2a and the bottom surface of the structural steel 2a is slightly larger than the diameter of such a roller as the fixed guide rail 2 In addition, the engaging roller 1b of the movable guide rail 1 has its roller shaft directly pivotally attached to both webs of the movable guide rail 1, and the lower end of the engaging roller 1b is more engaging than the back surface of the bottom surface of the section steel 1a of the movable guide rail 1. In the case where the roller 1 has a relatively small diameter so that it protrudes downward by the amount of protrusion 1c, the engagement means of the buffer mechanism 4 as the fixed guide rail 2 extends from the front end to the rear bottom surface of the section steel 2a. The lower side from 4b is stored. Recesses may be used those which are further formed.

  As shown in FIG. 2, FIG. 3, FIG. 5, FIG. 6 and FIG. 7, the engaging roller 1b is pivotally mounted so that each roller shaft is positioned below the bottom surface of the bottom surface of the section steel 1a. In this case, as described above, as the shape steel 2a of the fixed guide rail 2, the distance between the lower surface of the lip 2aa on the rear end side and the surface of the bottom surface of the shape steel 2a is large in accordance with the large engagement roller 1b. A concave part that accommodates the lower side of the engagement means 4b of the buffer mechanism 4 from the front end to the rear bottom surface of the shape steel 2a in accordance with the engagement roller 1b having a relatively large diameter or the weight of the engagement roller 1b. Since it is not necessary to use what is further formed or the like, it is preferable that the fixed guide rail 2 can be made as small and thin as possible and the material cost can be reduced.

  Furthermore, as the shape steel 2a of the fixed guide rail 2, for example, the height of the portion forming the groove shape on the front side thereof is the same as the height of the portion forming the lip groove shape on the rear side. 9, 10, and 11, the height of the portion forming the groove on the front side may be lower, and when forming such a shaped steel 2 a, the lip groove What is necessary is just to cut and shape the front side lip of the shaped steel.

  A support roller 2b for movably supporting the movable guide rail 1 is pivotally attached to the front end portion of the section steel 2a of the fixed guide rail 2. As the support roller 2b, for example, FIG. 2, FIG. 3 and FIG. As shown in FIG. 5, there can be exemplified those which are pivotally attached to the inner surface side of the front end portion of the shaped steel 2 a and movably support the lower surface of the movable guide rail 1.

  Reference numeral 3 denotes a fixed guide as the engaging roller 1b of the movable guide rail 1 moves to the front end side when the front end of the movable guide rail 1 which is continuous with the front end of the lip 2aa of the fixed guide rail 2 is tilted downward. An inclined guide piece 3a that guides and moves so that the distance from the contact point between the support roller 2b of the rail 2 and the movable guide rail 1 to the axis of the engaging roller 1b of the movable guide rail 1 gradually decreases, and the movable guide rail 1 A locking piece 3b is formed to maintain the movable guide rail 1 in an inclined state by locking the engaging roller 1b when the front end is tilted downward most. A pair of inclined guides fixed to both webs extending from the rear end to the front end of the two webs extending from the position to the front end, that is, the portion of the fixed guide rail 2 that forms the groove shape on the front side of the section 2a. The movable guide rail 1 that has been drawn forward by the engaging roller 1b of the movable guide rail 1 to the vicinity of the front end of the fixed guide rail 2 is guided and moved so that the front end tilts downward and is movable. The inclined state is maintained without leaving the guide rail 1.

  The inclined guide piece 3a of the inclined guide portion 3 is continuous with the front end of the lip 2aa of the section steel 2a of the fixed guide rail 2 as shown in FIGS. 2, 5, and 8 to 11, ie, the section steel 2a. Following the front end of the lip 2aa, the width of the shape steel 2a is approximately the same as that of the lip 2aa, and is formed so as to be substantially perpendicular to the respective webs of the shape steel 2a, like the lip 2aa of the shape steel 2a. At the same time, when the front end of the movable guide rail 1 drawn forward is inclined downward, the support roller 2b of the fixed guide rail 2 and the movable guide rail 1 are moved as the engaging roller 1b of the movable guide rail 1 moves to the front end side. The distance from the contact point to the axis of the engaging roller 1b of the movable guide rail 1 is formed so as to be gradually shortened.

  The movable guide rail 1 is drawn forward at the rear end of the inclined guide piece 3a of the inclined guide portion 3, and the engaging roller 1b of the movable guide rail 1 is moved to the front end of the lip 2aa of the fixed steel 2a. When moving from the side, the engaging means 1c of the movable guide rail 1 engages with the engaged means 4b of the buffer mechanism 4 to be described later, and the shock absorber 4a of the buffer mechanism 4 is integrated with the movable guide rail 1. Then, while rotating around the front end of the fixed guide rail 2, the engaging roller 1b of the movable guide rail 1 is in contact with the lower surface of the inclined guide piece 3a of the inclined guide portion 3 and forward from the rear end of the inclined guide piece 3a. The movable guide rail 1 gradually inclines forward as it moves to the position. At this time, the inclined guide piece 3a is fixed as the engaging roller 1b of the movable guide rail 1 moves to the front end side as described above. Movable with support roller 2b of rail 2 Since the distance from the contact point with the id rail 1 to the axis of the engaging roller 1b of the movable guide rail 1 is gradually reduced, the piston rod 4aa is pushed in when the piston rod 4aa is pushed into the cylinder 4ab. The movable guide rail 1 has a front end that gradually pushes the piston rod 4aa of the shock absorber 4a against the reaction force of the shock absorber 4a of the shock absorbing mechanism 4 in which a substantially constant reaction force acts on the displacement in the direction of movement. Since the movable guide rail 1 is gradually tilted downward, the movable guide rail 1 is not shifted to a state where the front end thereof is tilted downward by the reaction force of the shock absorber 4a. When a force for lifting the movable guide rail 1 is applied in order to perform an operation of lifting it up and storing it in the fixed guide rail 2, the movable guide rail 1 moves upward. Therefore, the movable guide rail 1 can be stored with a smaller force because the force is applied by the force applied when lifting and the reaction force of the shock absorber 4a.

  At this time, the inclination guide piece 3a of the inclination guide portion 3 is not intended to be inclined and guided so as to sandwich the engaging roller 1b of the movable guide rail 1 from above and below like the inclination guide member of the conventional apparatus. However, the inclined guide piece 3a can be inclined and guided only on the lower surface when the movable guide rail 1 is pulled forward, and the engaging roller 1b of the movable guide rail 1 is moved to the rear end side of the fixed guide rail 2. At the initial position, the center of gravity of the movable guide rail 1 is behind the support roller 2b, so that when viewed from the support roller 2b, a force is applied to move the engaging roller 1b of the movable guide rail 1 downward. When the movable guide rail 1 is further pulled forward so that the center of gravity of the movable guide rail 1 is located on the front side of the support roller 2b, the engagement roller 1b is moved upward with the support roller 2b as a fulcrum. The force to be applied acts and the force to move upward becomes larger as the distance between the support roller 2b and the engagement roller 1b becomes shorter as the movable guide rail 1 is pulled forward. Therefore, when the engaging roller 1b of the movable guide rail 1 is drawn forward to the vicinity of the front end of the lip 2aa of the fixed guide rail 2, the engaging means 1c of the movable guide rail 1 is covered by a buffer mechanism 4 described later. When the engaging roller 1b of the movable guide rail 1 engages with the engaging means 4b and starts to move to the rear end side of the inclined guide piece 3a of the inclined guide portion 3, the support roller 2b is moved by its own weight. Since the force to rotate and further shift to the front end side is canceled by the reaction force of the shock absorber 4a, only a strong force to move the engaging roller 1b at the rear end upward acts on the movable guide rail 1. Because

  The locking piece 3b of the inclined guide member 3 maintains the inclined state of the movable guide rail 1 by locking the engaging roller 1b when the front end of the movable guide rail 1 is tilted downward most. As the locking piece 3b, for example, a portion that is convex upward is formed continuously with the rear end of the inclined guide piece 3a, and the engaging roller 1b is locked at the convex portion, One in which the engaging roller 1b is locked by a projecting piece projecting downward on the rear end side of each of the inclined guide pieces 3a, FIG. 2, FIG. 3, FIG. 5, and FIG. A combination of these two can be illustrated as shown in FIG.

  As this inclination guide member 3, although the inclination guide piece 3a and the latching piece 3b are being fixed to the plate-shaped member by welding etc., for example in FIGS. 1-5 and FIGS. As shown, if the inclined guide piece 3a and the locking piece 3b are bent from the rear end of the upper edge side of the plate-like member to the front side, the inclined guide member 3 is formed by pressing or the like. Therefore, it is preferable that the processing cost can be reduced, and the engaging roller 1b is formed by a projecting piece projecting so as to face the lower side of the rear end side of the inclined guide piece 3a as the locking piece 3b. When there is something to be locked, as shown in FIGS. 8 to 12, the rear end portion of the inclined guide piece 3a of the plate-like member is punched inwardly except for one side. If processed, it is preferable that all the inclined guide members 3 can be formed by pressing or the like as described above. That's right.

  Further, as the inclined guide member 3, a flat plane is formed from a portion fixed to the web from a predetermined position in front of the fixed guide rail 2 to the front end portion to a portion reaching the inclined guide piece 3a and the locking piece 3b. However, as shown in FIGS. 3, 9, and 10, a portion above the portion fixed to the web from the predetermined position in front of the fixed guide rail 2 to the front end is a predetermined portion of the fixed guide rail 2. The engagement roller 1b of the movable guide rail 1 can be moved to the inclined guide portion 3 if the inner surface is processed so as to have a step corresponding to the thickness of the section steel 2a so as to be flush with the web extending from the position to the front end portion. Since there is no room left and right when moving along the inclined guide piece 3a, the lower surface of the engaging roller 1b that sways left and right forms the groove shape of the section steel 2a of the fixed guide rail 2 The phenomenon of galling on the upper edge side of It preferred to be able to completely prevent and.

  Further, as shown in FIGS. 1 to 5, the sound deadening member 5 made of an elastic body is opposed to the inner surface side of the both inclined guide members 3 and 3 with a slight space between the outer surface of the movable guide rail 1. And the movable guide rails 1 at the positions facing the silencing member 5 when the engaging roller 1b of the movable guide rail 1 is positioned at the rearmost side of the fixed guide rail 2, respectively. If the pair of leaf springs 6 and 6 slightly projecting in the direction of the sound deadening members 5 and 5 are fixed, when the movable guide rail 1 is stored on the fixed guide rail 2, the engaging roller of the movable guide rail 1 It is preferable that 1b can collide with the rear end side of the fixed guide rail 2 vigorously, so that it is possible to prevent a collision sound from being generated, and when the movable guide rail 1 is moved, the movable guide rail 1 becomes large. Left and right Therefore, it is preferable that the movable guide rail 1 can be stably moved with respect to the fixed guide rail 2.

  Since the pair of muffler members 5 and 5 fixed to the inner surface sides of the both inclined guide members 3 and 3 are fixed with a slight gap between them and the outer surface of the movable guide rail 1. When the portion of the movable guide rail 1 where the leaf spring 6 is not fixed passes through the portion of the muffler member 5, the movable guide rail 1 normally does not interfere with the movable guide rail 1. For example, when the movable guide rail 1 is swung to the left and right during operation, the portion of the movable guide rail 1 where the leaf spring 6 is not fixed comes into contact with the sound deadening member 5. It is possible to prevent the movable guide rail 1 from largely swinging left and right, and if the portion of the movable guide rail 1 where the leaf spring 6 is fixed tries to pass through the portion of the silencer member 5, Since the leaf spring 6 slightly protrudes in the direction of the silencer 5, the leaf spring 6 comes into contact with the silencer 5 and the moving speed of the movable guide rail 1 is attenuated by frictional resistance. It is possible to prevent a collision sound from being generated when the portion collides with the rear end side of the fixed guide rail 2 vigorously. The silencer member 5 may be anything as long as it is made of an elastic body, and for example, synthetic resin, rubber or the like is preferably used.

  4 shows that when the piston rod 4aa is pushed into the cylinder 4ab, a substantially constant reaction force acts on the displacement in the direction in which the piston rod 4aa is pushed, and the front end of the piston rod 4aa or the rear end of the cylinder 4ab is fixed. A shock absorber 4a pivotally supported at the front end of the guide rail 2 and an engaging roller 1b of the movable guide rail 1 fixed to the shock absorber 4a are drawn forward to the vicinity of the front end of the lip 2aa of the fixed guide rail 2. And the engagement means 4b that engages with the engagement means 1c of the movable guide rail 1 with the piston rod 4aa of the shock absorber 4a protruding most when the shock absorber 4a protrudes, and tilts the front end of the movable guide rail 1 downward The shock absorber 4a is sometimes a shock absorbing mechanism that is integrally formed with the movable guide rail 1 and rotates around the front end of the fixed guide rail 2. The movable guide rail 1 is lifted upward to move inside the fixed guide rail 2. The operation or the movable guide rail 1 for accommodating pull forward those to reduce the force applied at the time to do an operation that tilts the front end of the movable guide rail 1.

  The buffer mechanism 4 is configured so that the shock absorber 4a can be integrated with the movable guide rail 1 and can rotate around the front end of the fixed guide rail 2 when the front end of the movable guide rail 1 is tilted downward. At least when the movable guide rail 1 is pulled out substantially horizontally, it may be arranged so as not to collide with the bottom surface of the section of the movable guide rail 1. For example, the movable guide rail 1 is placed from the front end side of the fixed guide rail 1 along the rear bottom surface. In addition, the fixed guide rail 2 is placed in a recess that accommodates the lower side from the engaged means 4b of the buffer mechanism 4 from the front end to the rear bottom surface of the section 2a of the fixed guide rail 2. It may be deployed as follows.

  As shown in FIGS. 1 to 3, the shock absorber 4 a of the shock absorbing mechanism 4 is such that the movable guide rail 1 is pulled forward and the engaging roller 1 b of the movable guide rail 1 moves forward to the vicinity of the front end of the lip 2 aa of the fixed guide rail 2. When the piston rod 4aa of the shock absorber 4a is most protruded, the engaging means 1c of the movable guide rail 1 and the engaged means 4b of the shock absorbing mechanism 4 are engaged with each other. The engaging roller 1b is guided and moved by the inclined guide piece 3a of the inclined guide member 3, and the shock absorber 4a is integrated with the movable guide rail 1 and fixed guide when the movable guide rail 1 is tilted downward. When rotating around the front end of the rail 2, the piston rod 4aa is movable by applying a substantially constant reaction force to the displacement in the direction in which the piston rod 4aa is pushed when the piston rod 4aa is pushed into the cylinder 4ab. Guy The front end of the movable guide rail 1 is prevented from being inclined at a stretch due to the weight of the drag 1 or the weight of the movable guide rail 1 and the bicycle, and the movable guide rail 1 is pulled out and tilted as shown in FIGS. 1 to 3, the movable guide rail 1 is lifted upward and stored on the fixed guide rail 2 as shown in FIGS. 1 to 3. It is reduced.

  More specifically, when the downward tilt of the front end of the movable guide rail 1 is started, when the buffer mechanism 4 is not present, the front end of the movable guide rail 1 is moved by its own weight. Since the downward tilt is abruptly performed, in order to prevent the forward tilt of the front end of the movable guide rail 1 from being lowered downward, the front end of the movable guide rail 1 is supported while supporting the front end of the movable guide rail 1 with a large force. Although it is necessary to tilt downward, if the buffer mechanism 4 is present as in the device of the present invention, a sudden tilt downward of the front end of the movable guide rail 1 is caused by the reaction force of the buffer 4a of the buffer mechanism 4 Since the force required to tilt the front end of the movable guide rail 1 downward is small, even a powerless person such as a girl or a child can easily operate. When the buffer mechanism 4 is not lifted up and stored on the fixed guide rail 2, the weight of the movable guide rail 1 or the combined weight of the bicycle and the movable guide rail 1 is resisted. Since the front end of the movable guide rail 1 must be lifted until it becomes substantially horizontal, a very large force is required. However, if the buffer mechanism 4 exists as in the device of the present invention, the buffer mechanism 4 A part of the force required to lift the front end of the movable guide rail 1 until it becomes substantially horizontal is supported by the reaction force of the shock absorber 4a, so that the person who performs the operation moves the movable guide rail 1 upward with less force. It can be easily lifted, so that even weak people like girls and children can easily operate.

  As the shock absorber 4a of the shock absorbing mechanism 4, for example, a so-called gas spring can be used. An example of such a shock absorber 4a will be described with reference to FIG. A fluid and an incompressible fluid are filled with a free piston, and a piston rod 4aa connected to a piston sliding in the cylinder 4ab is inserted into a space filled with one incompressible fluid. In addition, an orifice is formed in the piston so that spaces on both sides of the piston communicate with each other, and incompressible fluids filled in the spaces on both sides of the piston are configured to be movable relative to each other. When an external force is applied to the piston rod 4aa of the gas spring having such a structure in the direction in which the piston rod 4aa is pushed into the cylinder 4ab, the piston is displaced in the cylinder 4ab due to the displacement of the piston rod 4aa, and the orifice formed in the piston is changed. The incompressible fluid moves from the space on the side where the piston rod 4aa does not exist in the cylinder 4ab to the space on the side where the piston rod 4aa exists, so the pressure difference on both sides of the piston is always the same. The free piston is displaced into the space on the side filled with the compressible fluid by the volume of the rod 4aa entering, and the space on the side filled with the compressive fluid is pressurized by the amount of displacement, so the piston rod A reaction force is generated in the gas spring against the external force in the direction in which 4aa is pushed. At this time, the displacement of the piston rod 4aa is accompanied by the phenomenon that the incompressible fluid moves from the space where the piston rod 4aa does not exist in the cylinder 4ab to the space where the piston rod 4aa exists. Since the piston rod 4aa cannot be displaced suddenly due to the resistance of the orifice formed in FIG. On the other hand, if the external force in the direction in which the piston rod 4aa is pushed becomes smaller than the reaction force generated in the gas spring in this state, or if the external force in the direction in which the piston rod 4aa is pushed is removed, the pressure of the compressive fluid The free piston is displaced into the space filled with the incompressible fluid, the volume of the space filled with the compressible fluid is increased, and the piston rod 4aa connected to the piston is displaced in the protruding direction. A force to return to the original position is generated. Such displacement of the piston rod 4aa is accompanied by the phenomenon that the incompressible fluid moves from the space where the piston rod 4aa exists in the cylinder 4ab to the space where the piston rod 4aa does not exist. Since the piston rod 4aa cannot be displaced suddenly due to the resistance of the orifice formed in FIG. Therefore, such a gas spring is in a state where the piston rod 4aa protrudes most by the pressure of the incompressible fluid when no external force is applied, and is pushed into the cylinder 4ab from this state into the piston 4aa. When an external force greater than or equal to a predetermined force is applied in the direction, the piston rod 4aa is displaced.

  The shock absorber 4a of the shock absorber mechanism 4 has a front end portion of the piston rod 4aa or a rear end portion of the cylinder 4ab pivotally supported by a front end portion of the fixed guide rail 2, for example, a bottom inner surface of the front end portion of the fixed guide rail 2. However, as shown in FIGS. 2, 3 and 5, the shock absorber 4a of the shock absorber 4 is pivoted on the roller shaft of the support roller 2b of the fixed guide rail 2. As shown in FIG. If it is attached, the engaging means 1c of the movable guide rail 1 and the engaged means 4b of the buffer mechanism 4 are engaged so that the shock absorber 4a is movable when the front end of the movable guide rail 1 is tilted downward. The moving direction of the piston rod 4aa of the shock absorber 4a of the shock absorbing mechanism 4 is substantially parallel to the longitudinal direction of the movable guide rail 1 while being integrated with the rail 1 and rotating around the front end of the fixed guide rail 2. Is required for the shock absorber 4a. This is not only preferable because the reaction force can be made smaller, but also because the support roller 2b and the shock absorber 4a are pivotally mounted on the same shaft, the number of parts can be reduced.

  As shown in FIGS. 1 to 3, the engaged means 4 b of the buffer mechanism 4 is configured to buffer when the engaging roller 1 b of the movable guide rail 1 is pulled forward to the vicinity of the front end of the lip 2 aa of the fixed guide rail 2. When the piston rod 4aa of the shock absorber 4a is most protruded and engages with the engaging means 1c of the movable guide rail 1, the reaction force of the shock absorber 4a can be reliably moved via the engaging means 1c of the movable guide rail 1. As the engaged means 4b, the front end of the piston rod 4aa of the shock absorber 4a is connected to the front end of the fixed guide rail 2, for example, as shown in FIGS. The engaging means 1c of the movable guide rail 1 that is axially supported and protrudes forward in a state having an opening between the bottom surface of the section steel 1a of the movable guide rail 1 at a predetermined interval in the width direction. In the case, the fixing guide is located above the cylinder 4ab of the shock absorber 4a. It may be in the form of a plate fixed so as to be substantially parallel to the bottom surface of the shape steel 2a of the rail 2, and the rear end of the cylinder 4ab of the shock absorber 4a is pivotally supported by the front end of the fixed guide rail 2. When the engaging means 1c of the movable guide rail 1 is a rod-shaped member disposed between the pair of engaging rollers 1b and 1b, the rear fixed to the tip of the piston rod 4aa of the shock absorber 4a May be made of a U-shaped jig having a space in the width direction and having a space in the width direction, but it is necessary to have a shape at least suitable for the engaging means 1c of the movable guide rail 1. is there.

  As shown in FIGS. 1 to 3, the engaging means 1c of the movable guide rail 1 and the engaged means 4b of the buffer mechanism 4 are pulled out forward and the engaging roller of the movable guide rail 1 is engaged. Immediately after the front end of the movable guide rail 1 drawn forward is tilted downward if 1b is arranged to engage when it comes into contact with the rear end of the tilt guide piece 3a of the tilt guide member 3. Since the engaging means 1c of the movable guide rail 1 and the engaged means 4b of the buffer mechanism 4 are engaged, the operation when the front end of the movable guide rail 1 tilts downward can be made smooth, which is preferable. In addition, the force required for the operation when the front end of the movable guide rail 1 tilts downward can be reduced, which is preferable.

  That is, the engaging roller 1b of the movable guide rail 1 is in the position near the front end of the lip 2aa of the fixed guide rail 2, and immediately before the engaging roller 1b contacts the rear end of the inclined guide piece 3a of the inclined guide member 3. The engaging means 1c of the movable guide rail 1 and the engaged means 4b of the buffer mechanism 4 with the piston rod 4aa of the shock absorber 4a protruding most at the position where it abuts the lower surface of the front end of the lip 2aa of the fixed guide rail 2 Are engaged, the engaging means 1c of the movable guide rail 1 and the engaged means 4b of the buffer mechanism 4 are engaged by a person who performs an operation of tilting the front end of the movable guide rail 1 downward. In the state where the reaction force by the shock absorber 4a of the shock absorbing mechanism 4 is applied to the movable guide rail 1, the movable guide rail 1 is slightly horizontal substantially against the reaction force by the shock absorber 4a and the weight of the movable guide rail 1 and the like. You have to pull it out Although the force required for the operation is very large, as described above, the engaging means 1c of the movable guide rail 1 and the engaged means 4b of the buffer mechanism 4 are movable by the movable guide rail 1 being pulled forward. When the engaging roller 1b of the guide rail 1 is arranged so as to be engaged when it comes into contact with the rear end of the inclined guide piece 3a of the inclined guide member 3, the movable guide rail 1 drawn forward is provided. Since the engaging means 1c of the movable guide rail 1 and the engaged means 4b of the buffer mechanism 4 engage with each other with the front end thereof slightly tilted downward, the reaction force by the shock absorber 4a and the weight of the movable guide rail 1, etc. The movable guide rail 1 does not need to be pulled out slightly to the near side, and the piston rod 4aa of the shock absorber 4a is naturally pushed by its own weight. 1 front end tilts downward It is Preferred to be able to reduce the force required to smoothly and the operation of the operation for.

Next, a description will be given of a method for parking a bicycle on the bicycle three-dimensional parking apparatus according to the present invention having such a configuration.
First, an operation of tilting the front end of the movable guide rail 1 by pulling the movable guide rail 1 forward is performed in a state where the bicycle is not placed on the movable guide rail 1 or the bicycle is already placed. In this operation, first, the movable guide rail 1 is housed in the fixed guide rail 2, that is, from the initial position where the engaging roller 1 b of the movable guide rail 1 is located at the most rear end side of the fixed guide rail 2. By pulling the guide rail 1 substantially horizontally forward, the movable guide rail 1 is moved until the engaging roller 1b of the movable guide rail 1 is positioned near the front end of the lip 2aa of the fixed guide rail 2 as shown in FIG. Move.

  At this time, since the center of gravity of the movable guide rail 1 is behind the support roller 2b of the fixed guide rail 2 at the initial position, the movable guide rail 1 is positioned below the engagement roller 1b of the movable guide rail 1 when viewed from the support roller 2b. The engagement roller 1b of the movable guide rail 1 is caused to travel along the surface of the bottom surface of the section steel 2a of the fixed guide rail 2 by the action of moving to the position of the movable guide rail 1. When the center of gravity is further pulled forward so that the center of gravity is located on the front side of the support roller 2b, the force to move downward to the engagement roller 1b with the support roller 2b as a fulcrum changes to the force to move upward. By doing so, the engaging roller 1b of the movable guide rail 1 is caused to travel along the back surface of the lip 2aa of the section steel 2a of the fixed guide rail 2.

  In this way, after the movable guide rail 1 is moved until the engagement roller 1b of the movable guide rail 1 is positioned in the vicinity of the front end of the lip 2aa of the fixed guide rail 2, the movable guide rail 1 is further moved forward. When pulled out, the engaging means 1c of the movable guide rail 1 and the engaged means 4b of the buffer mechanism 4 are engaged with the piston rod 4aa of the shock absorber 4a protruding most, and the engaging roller of the movable guide rail 1 is engaged. 1b is guided and moved by the lower surface of the inclined guide piece 3a of the inclined guide member 3 so that the shock absorber 4a is integrated with the movable guide rail 1 and moves around the front end of the fixed guide rail 2 as a movable guide. When the front end of the rail 1 gradually shifts to an inclined state, and then the engaging roller 1b of the movable guide rail 1 reaches the locking piece 3b of the inclined guide member 3, the movable guide rail 1 It is of being locked in a state in which the front end is inclined to the lowermost.

  At this time, when the engaging roller 1b of the movable guide rail 1 tries to travel from the rear end to the front end of the inclined guide piece 3a of the inclined guide member 3, the rear side of the movable guide rail 1 with the support roller 2b as a fulcrum is provided. The movable guide rail 1 itself is further rotated by rotating the support roller 2b by the large force to move upward and the front end side of the movable guide rail 1 tilting and the weight of the movable guide rail 1 or the weight of the movable guide rail 1 and the bicycle. The force to move to the front end side acts, and the force to move the movable guide rail 1 itself further to the front end side is a buffer that is engaged with the engaging means 1c of the movable guide rail 1. Since it is canceled out by the reaction force of the shock absorber 4a transmitted through the engaged means 4b of the mechanism 4, the engaging roller 1b of the movable guide rail 1 is caused by this large force to move upward. Is allowed to travel along the lower surface of the portion extending from the rear end to the front end of the inclined guide piece 3a without being separated from the inclined guide piece 3a of the inclined guide member 3.

  Thus, when the engaging roller 1b of the movable guide rail 1 is caused to travel along the lower surface of the portion extending from the rear end to the front end of the inclined guide piece 3a, the front end of the movable guide rail 1 is tilted downward. Since the distance from the contact point between the support roller 2b of the fixed guide rail 2 and the movable guide rail 1 to the axis of the engaging roller 1b of the movable guide rail 1 is gradually reduced, the movable guide rail 1 is As it is integrated with the shock absorber 4a and rotates around the front end of the fixed guide rail 2, it is engaged via the engaged means 4b of the shock absorbing mechanism 4 engaged with the engaging means 1c of the movable guide rail 1. The front end of the piston rod 4aa is gradually tilted against the reaction force of the shock absorber 4a that is transmitted, so that the front end of the piston rod 4aa is gradually inclined. Therefore, depending on the weight of the movable guide rail 1 or the weight of the movable guide rail 1 and the bicycle. Thus, the front end of the movable guide rail 1 is prevented from inclining at once, and the force for preventing the front end of the movable guide rail 1 from inclining at once is very small.

  Next, when the bicycle is placed on the movable guide rail 1 with the front end inclined as shown in FIG. 4 or when the bicycle is already placed on the movable guide rail 1 and this bicycle is to be carried out, the movable guide is used. After the bicycle is lowered from the rail 1, the movable guide rail 1 is pulled out and tilted, and then the movable guide rail 1 is lifted upward and the movable guide rail 1 is stored in the fixed guide rail 2. That is, the operation of retracting the movable guide rail 1 to the initial position where the engagement roller 1b of the movable guide rail 1 is located on the most rear end side of the fixed guide rail 2 is performed.

  In this operation, as shown in FIG. 4, the movable guide rail 1 is first pulled out and tilted, so that the engaging roller 1b of the movable guide rail 1 is positioned near the front end of the lip 2aa of the fixed guide rail 2. The front end of the movable guide rail 1 is lifted upward until the movable guide rail 1 is in a substantially horizontal state as shown in FIG.

  At this time, when a force for lifting the front end of the movable guide rail 1 is applied, the engagement roller 1b of the movable guide rail 1 is caused to travel along the lower surface of the portion extending from the front end to the rear end of the inclined guide piece 3a. As a result, the movable guide rail 1 is integrated with the shock absorber 4a and is rotated about the front end of the fixed guide rail 2. The movable guide rail 1 includes the weight of the movable guide rail 1 or the movable guide rail 1. In addition to the force to rotate the support roller 2b by its own weight and to move further to the front end side, it is transmitted via the engaged means 4b of the buffer mechanism 4 engaged with the engaging means 1c. The movable guide rail 1 is lifted with a smaller force because of the reaction force of the shock absorber 4a, that is, the force generated when the piston rod 4aa of the shock absorber 4a is displaced in the protruding direction and tries to return to the original position. be able to.

  Finally, after the engaging roller 1b of the movable guide rail 1 is positioned in the vicinity of the front end of the lip 2aa of the fixed guide rail 2 and the movable guide rail 1 becomes substantially horizontal as shown in FIG. 1 is pushed rearward, the movable guide rail 1 is housed on the fixed guide rail 2, that is, the engagement roller 1 b of the movable guide rail 1 is moved to the initial position located on the most rear end side of the fixed guide rail 2. And can be moved.
