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, a two-tiered bicycle parking system that can efficiently park bicycles on a limited area has been developed, and installed in the vicinity of stations and shopping streets, etc. It is effective against problems.

  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. It took a lot of labor, and it was very dangerous to carry in and out the bicycle.

  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 comprising 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 engaged with the front end portion of the guide portion for tilting the guide member. This is a bicycle three-dimensional bicycle parking apparatus provided with a stopper for stopping, 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 displacement in the direction in which the piston rod is pushed in When the shock absorber with a substantially constant reaction force is pulled out from the movable guide rail and the engagement roller moves to the vicinity of the front end of the horizontal guide portion of the guide member, the piston rod protrudes most The engagement portion provided on the piston rod or cylinder on the rear end side of the shock absorber is engaged with the engagement portion provided on the movable guide rail so as to be integrated with the movable guide rail and fixed. It is arranged so that it can rotate around the front end at the front end in the guide rail, and the guide part for tilting the guide member is the distance from the contact point with the movable guide rail of the support roller that supports 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 becomes shorter toward the front end have been proposed.

  However, in such a bicycle three-dimensional parking device, not only can the sudden tilt of the movable guide rail be prevented by a shock absorber in which a substantially constant reaction force acts on the displacement in the direction in which the piston rod is pushed, Although it is easy and safe to carry in and out of the upper stage without applying a large force, the movable guide rail is lifted upward from the tilted state and stored in the fixed guide rail. When the operation is performed, the engagement between the engaging portion of the movable guide rail and the engaging portion of the shock absorber is disengaged, so that the shock absorber rotates around the front end at the front end portion in the fixed guide rail. As a result, the phenomenon of falling to the bottom of the fixed guide rail (hereinafter sometimes referred to as “shock-off phenomenon of the shock absorber”) often occurs. Ri, falling phenomenon of shock absorber is frequently in particular low outside temperature in winter or the like.

  As soon as such a shock absorber drop-off phenomenon occurs, the force applied to the movable guide rail by the shock absorber disappears all at once, so that the movable guide rail suddenly disappears for those who perform the operation of lifting the movable guide rail. For example, if a person who operates in such a state releases or weakens the force that lifts the movable guide rail upward, the movable guide rail is pulled out by its own weight. There was a problem that the person who performed the operation suffered an unexpected injury.

  Further, when the shock absorber has fallen off and the movable guide rail is further lifted upward and stored in the fixed guide rail, the movable guide rail is moved by the shock absorber as described above. As the force applied to the power vanishes at once, the operator must not only apply a strong force to lift the movable guide rail upward, but also falls to the bottom of the fixed guide rail first. The engaging roller and the engaging roller located at the rear end of the movable guide rail coming to the shock absorber interfere with each other to move the engaging roller of the movable guide rail into the horizontal guide portion of the fixed guide rail. There is also a problem that the movable guide rail cannot be stored in the fixed guide rail.

  The present invention solves the above-mentioned problems of the prior art, and when performing an operation of lifting the movable guide rail upward and storing it in the fixed guide rail, the shock absorber is at the front end portion in the fixed guide rail all at once. It is possible to completely prevent the phenomenon of rotating and falling to the bottom of the fixed guide rail, and to carry out the work in and out of the upper stage of the bicycle easily and safely without applying a large force. It is an object of the present invention to provide a bicycle three-dimensional parking device that can be used.

The present inventors have result of intensive studies to solve the above problems, and if the person who performs the operation has gone very vigorously lifted from a state of being tilted drawn movable guide rail upward the movable guide rail, If the viscosity of oil, which is an incompressible fluid in the shock absorber, increases in winter when the outside air temperature is low, the speed when the piston rod of the shock absorber is displaced in the protruding direction decreases. Due to various factors, the speed at which the engaging portion provided on the movable guide rail moves away from the contact point between the movable guide rail and the support roller is faster than the speed at which the biston rod of the shock absorber is projected. If this happens, the engaging part of the movable guide rail and the engaging part of the shock absorber will be disengaged, and the shock absorber will rotate around the front end at the front end in the fixed guide rail. Paying attention to the phenomenon, if there is a speed difference between the movement of the shock absorber biston rod and the movable guide rail, the engagement between the movable guide rail and the shock absorber will be disengaged. Even if the shock absorber is held at the front end portion in the fixed guide rail so as not to rotate at a stretch around the front end, the movable guide rail engaging portion and the shock absorber engaging portion are held in this state. If a mechanism is provided that can return the engaged state from the disengaged state to the reengaged state, the movable guide rail is lifted upward to be buffered when the operation is stored in the fixed guide rail. It is possible to completely prevent the device from rotating at once at the front end in the fixed guide rail and centering on the front end and falling to the bottom in the fixed guide rail. Than is the present invention has been completed by investigating that the loading and unloading operations can be easily and safely carried out without applying a large force to.

This is a bicycle three-dimensional bicycle parking device characterized by comprising:

  If the support roller of the fixed guide rail and the front end of the piston rod of the shock absorber of the shock absorber are pivoted on the same axis, the engagement piece of the engagement means of the movable guide rail and the cover of the shock absorber In a state where the movable guide rail and the buffer mechanism are integrated with each other and the engaging part of the engagement means is engaged, and the front end portion in the fixed guide rail rotates around the front end. It has also been found that the direction of movement of the piston rod of the shock absorber 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 further reduced.

  Further, the engaging roller of the movable guide rail is pivotally attached to a position below the lower surface of the rear end portion of the movable guide rail and outside the respective side surfaces of the movable guide rail, and the fixed guide. The rail is made of lip-groove shaped steel, and the guide part for the horizontal part of the guide part is formed by the lip and the bottom, and the forming member in which the guide part for tilting the guide part and the stopper are integrated on the front end side of the steel part. It has also been found that the fixed guide rail can be thinned if it is fixed.

  Furthermore, it is made of an elastic body with a slight space between the outer surface of the movable guide rail at a position above the support roller of the fixed guide rail and at the position facing each outer surface of the movable guide rail. A pair of sound-extinguishing members that are fixed to each other and that slightly project in the direction of the respective sound-absorbing members that face the moving guide rails that face the sound-absorbing members when the movable guide rail is positioned at the rearmost side. If the leaf spring is fixed, when the movable guide rail is housed in the fixed guide rail, the rear end of the movable guide rail collides with the rear end side of the fixed guide rail. It has also been found that it is preferable to prevent this.

In the bicycle three-dimensional parking device according to the present invention, a movable guide rail made of a shape steel having a groove shape, a lip groove shape or a hat shape with an open top is shaped below the rear end portion at a predetermined interval in the width direction. A pair of engagement pieces projecting forward in a state of having an opening between the bottom surface of each of them and forming an engagement receiving portion, and a shape steel at a predetermined interval in the width direction on the rear side of both engagement pieces When the piston rod is pushed into the cylinder, it has engaging means consisting of a pair of auxiliary pieces that protrude in directions opposite to each other in a state of having an opening between the bottom surface of the cylinder and each of the auxiliary receiving portions. A substantially constant reaction force acts on the displacement in the direction in which the piston rod is pushed in, and a shock absorber in which the front end of the piston rod is pivotally supported by the front end of the fixed guide rail and the movable guide rail are pulled forward. Please When the engaging roller of the moving guide rail moves to the vicinity of the front end of the horizontal guide portion of the guide portion of the fixed guide rail, the engagement receiving portions of the engaging pieces of the engaging means of the movable guide rail are moved forward. engaging portion upper surface parts are engaged, each formed along a cylinder so as to be positioned just above the auxiliary receiving portions engaging both the auxiliary pieces of the engagement means at the rear side of the engagement portion An auxiliary portion that is held by the respective auxiliary receiving portions of the auxiliary pieces when the receiving portion and the engaging portion are disengaged, and includes an engaged means fixed to the cylinder of the shock absorber. The shock absorber is equipped with a shock absorber mechanism that is integrated with the movable guide rail and rotates around the front end of the fixed guide rail when the front end of the movable guide rail is tilted downward. Lift the guide rail upward to secure When the storage operation is performed in the guide rail, a speed difference occurs between the movement of the buffer rod and the movable guide rail so that the engagement piece of the engagement means of the movable guide rail and the engagement means of the buffer mechanism Even if the engagement with the engaging portion is disengaged, the buffering mechanism is buffered by the auxiliary piece of the engaging means of the movable guide rail so that the buffering mechanism does not rotate around the front end at the front end in the fixed guide rail. By holding the auxiliary part of the engaged means of the mechanism, the phenomenon that the buffer mechanism falls to the bottom of the fixed guide rail does not occur at all, so it is applied to the movable guide rail by the buffer of the buffer mechanism. When the power is lost, the person who performs the operation must apply a strong force to lift the movable guide rail upward in order to maintain the position of the movable guide rail. The movable guide rail is caused by interference between the engagement means and the engagement roller located at the rear end of the movable guide rail that comes later to the buffer mechanism that has fallen to the bottom of the fixed guide rail. Therefore, it is possible to completely prevent the engagement roller from being moved into the horizontal guide portion of the fixed guide rail and the movable guide rail from being stored in the fixed guide rail.

  When the movable guide rail is pulled forward and the engaging roller of the movable guide rail moves to the vicinity of the front end of the horizontal guide portion of the guide portion of the fixed guide rail. The auxiliary portion of the engaged means of the buffer mechanism is engaged with the movable guide rail on the rear side of the engaging portion where the upper surfaces of the respective engagement receiving portions of the engaging pieces of the engaging means of the movable guide rail are engaged. Since it is formed so as to be positioned slightly above the respective auxiliary receiving portions of the auxiliary pieces of the coupling means, when performing an operation of lifting the movable guide rail upward and storing it in the fixed guide rail, a buffer mechanism is temporarily provided. Even if the speed difference occurs between the movement of the biston rod and the movable guide rail, the engagement piece of the engagement means of the movable guide rail and the engagement portion of the engaged means of the buffer mechanism are disengaged. , Buffer mechanism In addition to being able to hold the auxiliary portion of the engaged means of the buffer mechanism with the auxiliary piece of the engaging means of the movable guide rail so that it does not rotate around the front end at the front end portion in the fixed guide rail, Since the auxiliary portion of the engaged means of the buffer mechanism can freely move between the auxiliary receiving portions of the auxiliary pieces of the engaging means of the movable guide rail while holding the buffer mechanism, If the force that lifts the movable guide rail upward is weakened or released while the engagement between the engagement piece of the engagement means and the engagement portion of the engagement means of the buffer mechanism is disengaged, the buffer The piston rod of the shock absorber of the mechanism is pushed out by the reaction force, so that the engagement piece of the engaging means of the movable guide rail and the engaging portion of the engaged means of the buffer mechanism are again engaged. It is possible Therefore, even when the engagement between the engaging piece of the engaging means of the movable guide rail and the engaging portion of the engaged means of the buffer mechanism is released, the movable guide rail is pulled out by its own weight and tilted. Therefore, it is possible to improve the safety of a person who does not incur an unexpected injury so that the person who performs the operation is not injured unexpectedly.

  Further, if the support roller of the fixed guide rail and the front end portion of the piston rod of the shock absorber of the shock absorber are pivoted on the same axis, the engagement piece of the engagement means of the movable guide rail and the cover of the shock absorber In a state where the movable guide rail and the buffer mechanism are integrated with each other and the engaging part of the engagement means is engaged, and the front end portion in the fixed guide rail rotates around the front end. Since the moving direction of the piston rod of the shock absorber can be made substantially parallel to the longitudinal direction of the movable guide rail, the reaction force required for the shock absorber can be made smaller, which is preferable. Since the piston rod is pivotally mounted on the same axis, the number of parts can be reduced, which is preferable.

  Further, the engaging roller of the movable guide rail is pivotally attached to a position below the lower surface of the rear end portion of the movable guide rail and outside the respective side surfaces of the movable guide rail, and the fixed guide. The rail is made of lip-groove shaped steel, and the guide part for the horizontal part of the guide part is formed by the lip and the bottom, and the forming member in which the guide part for tilting the guide part and the stopper are integrally formed on the front end side of the steel part. If fixed, the fixed guide rail can be reduced in thickness, which is preferable, and the fixed guide rail can be reduced in weight. Therefore, the frame such as a column and a cross beam to which the fixed guide rail is fixed is thin and lightweight. Therefore, the entire device of the present invention can be reduced in weight and the manufacturing cost can be reduced, which is preferable.

  Furthermore, it is made of an elastic body with a slight space between the outer surface of the movable guide rail at a position above the support roller of the fixed guide rail and at the position facing each outer surface of the movable guide rail. The silencing members are respectively fixed, and slightly project in the direction of the respective silencing members facing the movable guide rails at positions facing the silencing members when the movable guide rail is positioned at the rearmost side. If the pair of leaf springs are fixed, when the movable guide rail is housed in the fixed guide rail, the rear end of the movable guide rail collides with the rear end of the fixed guide rail vigorously, so that a collision sound is generated. This is not only desirable, but also prevents the movable guide rail from swinging left and right when the movable guide rail is moved. It is possible to preferably be able to perform a movement relative to the stationary guide rail of the movable guide rail stably.

The shape steel 2a of the fixed guide rail 2 is not particularly limited as long as it is made of a shape steel having a groove shape, a lip groove shape or a hat shape with an open top so that the movable guide rail 1 can be accommodated. Further, a support roller 2b for movably supporting the movable guide rail 1 is required to be pivotally attached to the front end portion of the shape steel 2a. As the support roller 2b, FIG. 2, FIG. 3, FIG. As shown in FIG. 6, it is pivotally attached to the inner surface of the bottom of the front end of the shaped steel 2a, and supports the lower surface of the movable guide rail 1 movably, or both inner side surfaces of the front end of the shaped steel 2a although not shown. The movable guide rail 1 is made of a hat-shaped section 1a and movably supports the lower surfaces of both hat portions of the movable guide rail 1 as shown in FIGS. As shown in Fig. 8, both ends of the front end of the section 2a A pair of U-shaped rails are pivotally mounted so as to face the side surfaces, and a pair of U-shaped rails are separately fixed to both outer side surfaces of the movable guide rail 1 with the openings facing outward. It may be one that is movably supported.

  The guide portion 2c formed on the fixed guide rail 2 engages with an engagement roller 1b pivotally attached to both sides of the rear end portion of the movable guide rail 1, thereby restricting and guiding the moving direction of the movable guide rail 2. In order to move the movable guide rail 1 substantially horizontally, the fixed guide rail 2 has a predetermined length from the rear end side to the front side, that is, even if the movable guide rail 1 is tilted, The substantially horizontal horizontal guide part 2ca having a length that can be pulled out to a position where it does not come into contact with a bicycle parked downward, and the front end of the movable guide rail 1 drawn forward are inclined downward. In addition, as the engagement roller 1b of the movable guide rail 1 goes to the front end side, the guide roller is moved so that the distance from the contact point between the support roller 2b and the movable guide rail 1 to the axis of the engagement roller 1b gradually decreases. When the tilting guide portion 2cb and the movable guide rail 1 are pulled forward and the front end thereof is tilted downward, the engagement roller 1b of the movable guide rail 1 is locked and the movable guide rail 1 is moved from the fixed guide rail 2. The stopper 2cc is provided at the front end portion of the tilt guide portion 2cb to prevent it from coming off and falling off.

  The tilting guide portion 2cb of the guide portion 2c of the fixed guide rail 2 may be, for example, a straight portion, although not shown, and as shown in FIGS. 2, 3, 5, and 7. Although it may be curved, it is movable with the support roller 2b so that at least the front end of the movable guide rail 1 drawn forward is inclined downward and the engaging roller 1b of the movable guide rail 1 goes to the front end side. There is no particular limitation as long as it can be guided and moved so that the distance from the contact point with the guide rail 1 to the axis of the engaging roller 1b is gradually reduced.

  That is, the tilting guide portion 2cb of the guide portion 2c is such that the movable guide rail 1 is pulled forward and the engaging roller 1b of the movable guide rail 1 moves from the rear end side of the tilting guide portion 2cb of the fixed guide rail 2 to the front end. When moving toward the front, the front end of the movable guide rail 1 tilts downward, that is, the front end of the movable guide rail 1 gradually moves with the contact point between the support roller 2b of the fixed guide rail 2 and the movable guide rail 1 as a fulcrum. At this time, the movable guide rail 1 is inclined so as to be positioned below the fulcrum. At the same time, the engaging roller 1b of the movable guide rail 1 moves with the support roller 2b of the fixed guide rail 2 as it goes to the front end side. Since the guide is moved so that the distance from the contact point with the guide rail 1 to the shaft center of the engaging roller 1b is gradually shortened, the movable guide rail 1 is pulled forward to move the movable guide rail. When the engaging roller 1b of the guide 1 moves to the vicinity of the front end of the horizontal guide portion 2ca of the guide portion 2c of the fixed guide rail 2, both the engaging pieces 1ca and 1ca of the engaging means 1c of the movable guide rail 1 are described later. The engaging portion 3ba of the engaged means 3b of the buffer mechanism 3 to be engaged is engaged, and a buffer 3a of the buffer mechanism 3 to be described later is integrated with the movable guide rail 1 at the front end portion in the fixed guide rail 2. The piston of the shock absorber 3a in which a substantially constant reaction force acts on the displacement in the push-in direction due to the weight of the movable guide rail 1 or the weight of the movable guide rail 1 and the bicycle when rotating about the front end. Since the front end of the movable guide rail 1 gradually tilts downward while pushing the rod 3aa gradually, the movable guide rail 1 shifts to a state where the front end tilts downward due to the reaction force of the shock absorber 3a. And never When the movable guide rail 1 is lifted upward in order to perform the operation of lifting the movable guide rail 1 upward and storing it in the fixed guide rail 2 from the tilted state, the movable guide rail 1 moves upward. Therefore, the movable guide rail 1 can be accommodated with a smaller force because it is lifted by the force applied when it is lifted and the reaction force of the shock absorber 3a.

  As the guide portion 2c of the fixed guide rail 2, for example, as shown in FIGS. 7 and 8, guide portions 2c made of rails having a U-shaped cross section are opposed to each other on both inner side surfaces of the shaped steel 2a. The engaging roller 1b of the movable guide rail 1 is located below the lower surface of the rear end portion of the movable guide rail 1 as shown in FIGS. In addition, the movable guide rail 1 is pivotally attached to a position outside the respective side surfaces, and the fixed guide rail 2 is formed of a lip groove shaped steel 2a, and the horizontal guide portion of the guide portion 2c with the lip and the bottom surface. If the forming member 4 in which the guide portion 2cb for tilting the guide portion 2c and the stopper 2cc are integrated is fixed to the front end side of the shape steel 2a, the fixed guide rail 2 can be thinned. Not only is it preferable, but the fixed guide rail 2 Since the weight can be reduced, the frame F such as a column or a cross beam to which the fixed guide rail 2 is fixed can be formed of a thin and light steel material, so that the entire device of the present invention can be reduced in weight and the manufacturing cost can be reduced. As the forming member 4, for example, as shown in FIGS. 2, 3, and 5, a tilt guide portion 2cb and a stopper 2cc are integrally fixed to a pair of plate-like members. Used.

  As shown in FIGS. 1 to 6, the fixed guide rail 2 is positioned above the support roller 2b and is opposed to the outer surface of the movable guide rail 1 between the outer surfaces of the movable guide rail 1. The sound deadening member 5 made of an elastic body is fixed in a state where a slight gap is provided between the movable guide rail 1 and the movable guide rail at a position facing the sound deadening member 5 when the movable guide rail 1 is positioned at the rearmost side. 1, if a pair of leaf springs 6, 6 slightly projecting in the direction of the respective silencer members 5 facing each other is fixed, the movable guide rail 1 is stored when the movable guide rail 1 is stored in the fixed guide rail 2. It is preferable not only that the rear end portion of 1 collides with the rear end side of the fixed guide rail 2 vigorously, but this is preferable, and the movable guide rail 1 is moved. Since that the movable guide rail 1 resulting in deflection increases to the left and right can be prevented, preferably it is able to perform a movement relative to the stationary guide rail 2 of the movable guide rail 1 stably.

  The pair of sound deadening members 5, 5 fixed at positions above the support roller 2 b of the fixed guide rail 2 and facing the respective outer surfaces of the movable guide rail 1 are the outer surfaces of the movable guide rail 1. Are fixed in a state where a slight gap is provided between the movable guide rail 1 and the part where the leaf spring 6 of the movable guide rail 1 is not fixed passes through the part of the silencer member 5. Since the movable guide rail 1 can move smoothly because it does not interfere with the guide rail 1, for example, when the movable guide rail 1 is swung to the left and right during operation, the plate of the movable guide rail 1 is used. Since the portion where the 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 swinging to the left and right, and the movable guide rail. When the portion where the first leaf spring 6 is fixed passes through the portion of the silencer member 5, the leaf spring 6 slightly protrudes in the direction of the silencer member 5. Since the moving speed of the movable guide rail 1 is attenuated by the contact and frictional resistance, the rear end portion of the movable guide rail 1 is prevented from colliding with the rear end side of the fixed guide rail 2 to generate a collision sound. It can be done.

  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.

3 shows that when the piston rod 3aa is pushed into the cylinder 3ab, a substantially constant reaction force acts on the displacement in the direction in which the piston rod 3aa is pushed, and the front end of the piston rod 3aa is brought to the front end of the fixed guide rail 2. The shock absorber 3a supported by the shaft and the movable guide rail 1 are pulled forward, and the engaging roller 1b of the movable guide rail 1 moves to the vicinity of the front end of the horizontal guide portion 2ca of the guide portion 2c of the fixed guide rail 2. The engagement portion 3ba with which the upper surfaces of the respective engagement receiving portions 1caa, 1caa of the engagement pieces 1ca, 1ca of the engagement means 1c of the movable guide rail 1 are engaged , Formed along the cylinder 3ab so as to be positioned slightly above the respective auxiliary receiving portions 1cba, 1cba of the auxiliary pieces 1cb, 1cb of the engaging means 1c on the rear side of the 3ba, the engaging receiving portions 1caa, 1caa and the When the engagement with the engagement portion 3ba is disengaged, the auxiliary pieces 1cb and 1cb are Respectively of the auxiliary receiving portion 1Cba, it consists auxiliary portion 3bb and held by 1Cba, provided with the engaged means 3b which is fixed to the cylinder 3ab dampers 3a, the movable guide rail 1 of the front end The shock absorber 3a is a shock absorbing mechanism that rotates integrally with the movable guide rail 1 at the front end portion of the fixed guide rail 2 when it is tilted downward, and lifts the movable guide rail 1 upward. fixing the operation or the movable guide rail 1 to be stored in the guide rail 2 with the drawer forward reduces the force applied in the Hare line operation that tilts the front end of the movable guide rail 1, is drawn movable guide rail 1 Te When the movable guide rail 1 is lifted upward from the tilted state and stored in the fixed guide rail 2, the engaging means 1 c of the movable guide rail 1 and the engaged means 3 b of the buffer mechanism 3 Due to the disengagement, the shock absorbing mechanism 3 prevents the phenomenon that the front end portion in the fixed guide rail 2 rotates around the front end and falls to the bottom portion in the fixed guide rail 2. ing.

That is, the shock absorber 3a of the shock absorbing mechanism 3 is configured so that the movable guide rail 1 is pulled forward as shown in FIGS. 4 and 5, and the engaging roller 1b of the movable guide rail 1 is used for horizontally guiding the guide portion 2c of the fixed guide rail 2. When moving to the vicinity of the front end of the guide portion 2ca, the engaging pieces 1ca and 1ca of the engaging means 1c of the movable guide rail 1 and the engaging portion 3ba of the engaged means 3b of the buffer mechanism 3 are engaged. The engagement roller 1b of the movable guide rail 1 is guided and moved by the tilting guide portion 2cb, and the buffer mechanism 3 of the guide portion 2c of the fixed guide rail 2 is integrated with the movable guide rail 1 so that the fixed guide rail 2 When the piston rod 3aa is pushed into the cylinder 3ab when the piston rod 3aa is pushed into the cylinder 3ab, a substantially constant reaction force is applied to the displacement in the direction in which the piston rod 3aa is pushed. The movable guide rail 1 itself Or together once the front end of the movable guide rail 1 by the weight of the movable guide rail 1 and the bicycle is prevented from being inclined, shown in FIG. 4 from the movable guide rail 1 is inclined pulled out as shown in FIG. 1 when performing an operation for housing the fixed guide rail 2 by lifting the movable guide rail 1 upwardly as is the reduce the force to be applied to carrying out this operation by the said reaction force.

As the shock absorber 3a of the shock absorbing mechanism 3, for example, a so-called gas spring can be used. An example of such a shock absorber 3a will be described with reference to FIG. A fluid and an incompressible fluid are filled with a free piston, and a piston rod 3aa connected to a piston that slides in the cylinder 3ab is inserted into a space filled with the 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 3aa of the gas spring having such a structure in the direction of being pushed into the cylinder 3ab, the piston is displaced in the cylinder 3ab due to the displacement of the piston rod 3aa, and the orifice formed in the piston is moved. The incompressible fluid moves from the space where the piston rod 3aa does not exist in the cylinder 3ab to the space where the piston rod 3aa exists, so the pressure difference on both sides of the piston is always equal, but the piston in the cylinder 3ab The free piston is displaced into the space on the side filled with the compressible fluid by the volume of the rod 3aa 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 against the external force in the direction in which 3aa is pushed is generated in the gas spring. At this time, the displacement of the piston rod 3aa is accompanied by a phenomenon in which the incompressible fluid moves from the space where the piston rod 3aa does not exist in the cylinder 3ab to the space where the piston rod 3aa exists. cushioning effect is obtained because the piston rod 3aa can not rapidly displaced by the resistance of the orifice formed in the. On the other hand, if the external force in the direction in which the piston rod 3aa is pushed is 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 3aa 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 3aa 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 3aa is accompanied by the phenomenon that the incompressible fluid moves from the space on the side where the piston rod 3aa exists in the cylinder 3ab to the space on the side where the piston rod 3aa does not exist. Since the piston rod 3aa 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 3aa protrudes most by the pressure of the incompressible fluid when no external force is applied, and is pushed into the cylinder 3ab from this state into the piston rod 3aa. When an external force greater than a predetermined force is applied in the direction, the piston rod 3aa is displaced.

  The shock absorber 3a of the shock absorbing mechanism 3 has a front end portion of the piston rod 3aa that is pivotally supported by the front end portion of the fixed guide rail 2. For example, as shown in FIG. 2, 3, 5, and 6, the support roller 2 b of the fixed guide rail 2 and the piston of the shock absorber 3 a of the buffer mechanism 3 may be supported. If the front end of the rod 3aa is pivotally mounted on the same axis, the engagement piece 1ca of the engagement means 1c of the movable guide rail 1 and the engagement portion 3ba of the engagement means 3b of the buffer mechanism 3 are connected. The movable guide rail 1 and the buffer mechanism 3 are integrally engaged with each other so that the front end of the fixed guide rail 2 rotates around the front end of the shock absorber 3a of the buffer mechanism 3. The moving direction of the piston rod 3aa is substantially parallel to the longitudinal direction of the movable guide rail 1. Therefore, not only is the reaction force required for the shock absorber 3a smaller, which is preferable, but the support roller 2b and the piston rod 3aa are pivotally mounted on the same axis, so the number of parts can be reduced. This is preferable because it can be reduced.

As shown in FIG. 5, the engaged means 3b of the buffer mechanism 3 is such that the movable guide rail 1 is pulled forward, and the engaging roller 1b of the movable guide rail 1 is the horizontal guide portion of the guide portion 2c of the fixed guide rail 2. Engagement in which the upper surfaces of the respective engagement receiving portions 1caa and 1caa of the engagement pieces 1ca and 1ca of the engagement means 1c of the movable guide rail 1 are engaged on the front side when moving to the vicinity of the front end of 2ca A portion 3ba and an engagement formed on the rear side of the engagement portion 3ba along the cylinder 3ab so as to be positioned slightly above the respective auxiliary receiving portions 1cba and 1cba of the auxiliary pieces 1cb and 1cb of the engaging means 1c. receiving 1Caa, it consists 1Caa engaging portion 3ba both aids in engagement are out of 1cb, each of the auxiliary receiving portions 1Cba of 1cb, an auxiliary portion 3bb held by 1Cba, cylinder of the damper 3a It is fixed to 3ab, and its engaging part 3ba is movable guide rail 1 as shown in FIGS. By engaging with the upper surfaces of the respective engagement receiving portions 1caa, 1caa of the both engagement pieces 1ca, 1ca of the engagement means 1c, the reaction force of the shock absorber 3a is applied to both the engagement pieces 1ca, 1ca of the engagement means 1c. Even when the above-mentioned engagement is disengaged when performing an operation of lifting the movable guide rail 1 upward and storing it in the fixed guide rail 2, 3, the auxiliary portion 3bb is held by both auxiliary pieces 1cb and 1cb of the engaging means 1c of the movable guide rail 1 so that the shock absorber 3a is centered on the front end of the fixed guide rail 2 at its front end. Preventing the phenomenon of rotating at a stroke and falling to the bottom of the fixed guide rail 2, and weakening or releasing the force to lift the movable guide rail 1 upward when the engagement is disengaged as described above In the meantime, the pin of the shock absorber 3a of the shock absorber 3 is in the meantime. By Tonroddo 3aa extends by its reaction force can be restored again to the engaged state.

  As the engaged means 3b of the buffer mechanism 3, for example, as shown in FIGS. 12 to 14, the width of the buffer rod 3a on the piston rod 3aa side above the case in which the cylinder 3ab of the buffer 3a is accommodated is larger than the width of the case. A wide plate-like engagement part 3ba, and the rear part of the engagement part 3ba has a vertical position substantially coincident with the engagement part 3ba and its width is wider than the width of the case and the engagement part Even if it consists of a plate-like auxiliary part 3bb formed over the rear end side of the case narrower than the width of 3ba, the engaging part 3ba located on the piston rod 3aa side and this engaging part 3ba The auxiliary portion 3bb is formed on the rear side of the auxiliary portion 3bb so as to be positioned below the engaging portion 3ba at a predetermined interval. However, at least in accordance with the engaging means 1c of the movable guide rail 1. It is necessary to have the shape.

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 that is normally inserted into the fixed guide rail 2 is pulled out substantially horizontally and the engaging roller 1b of the movable guide rail 1 is moved to the fixed guide rail 2 as shown in FIG. The movable guide rail 1 is moved until it is positioned near the front end of the horizontal guide portion 2ca of the guide portion 2c.

At this time, the movable guide rail 1 is supported by the support roller 2b pivotally attached to the front end portion of the fixed guide rail 2. For example, in the embodiment shown in FIGS. 1 to 6, the front end of the section steel 2a of the fixed guide rail 2 is supported. 7 and 8, the lower surface of the movable guide rail 1 is in contact with the support roller 2b pivotally attached to the bottom inner surface side, and in the embodiment shown in FIGS. A pair of separate U-shaped rails, which are fixed to a pair of pivoted support rollers 2b, 2b, are fixed to both outer surfaces of the movable guide rail 1 with their openings facing outward. The engaging roller 1b that is supported and pivotally mounted on both sides of the rear end of the movable guide rail 1 has a horizontal guide portion 2ca of the guide portion 2c of the fixed guide rail 2 (the center of gravity of the movable guide rail 1 and the like is When it is on the fixed guide rail 2 side from the support roller 2b The movable guide rail 2 comes into contact with the upper surface of the lower surface of the horizontal guide portion 2ca, or the lower surface of the upper surface of the horizontal guide portion 2ca when it is on the opposite side of the fixed guide rail 2 from the support roller 2b. However, at first, it is guided substantially horizontally along the horizontal guide portion 2ca of the guide portion 2c. However, if the support roller 2b and the engagement roller 1b are made of resin, the effect of buffering and silencing can be obtained. It is preferable because it is possible.

  In this way, when the movable guide rail 1 is further pulled out forward after the engaging roller 1b of the movable guide rail 1 is positioned near the front end of the horizontal guide portion 2ca of the guide portion 2c of the fixed guide rail 2, the movable guide rail 1 The upper surface of each engagement receiving portion 1caa, 1caa of both engagement pieces 1ca, 1ca of one engagement means 1c engages with the engagement portion 3ba of the engagement means 3b of the buffer mechanism 3 and is engaged The auxiliary portion 3bb of the means 3b is located slightly above the auxiliary receiving portions 1cba and 1cba of the auxiliary pieces 1cb and 1cb of the engaging means 1c, and the engaging roller 1b of the movable guide rail 1 is tilted to the guide portion 2cb for tilting. The buffer mechanism 3 of the guide portion 2c of the fixed guide rail 2 is integrated with the movable guide rail 1 and rotated around the front end of the fixed guide rail 2 around the front end. The rail 1 gradually shifts to a state in which the front end is inclined.

At this time, when the bicycle is already placed on the movable guide rail 1 and the weight of the movable guide rail 1, the weight of the bicycle is reduced by the buffer mechanism 3 engaged with the engaging means 1 c of the movable guide rail 1. It is transmitted to the shock absorber 3a via the engagement portion 3ba of the engaged means 3b, and a force is applied in the direction in which the piston rod 3aa of the shock absorber 3a is pushed in, but the shock absorber 3a has its piston rod 3aa connected to the cylinder 3ab. When the piston rod 3aa is pushed in, a substantially constant reaction force is applied to the displacement in the direction in which the piston rod 3aa is pushed. Therefore, the movable guide rail 1 is moved at once by the weight of the movable guide rail 1 or the weight of the movable guide rail 1 and the bicycle. than it is possible to prevent the front end of thus inclined.

  Next, when the bicycle is placed on the movable guide rail 1 with the front end inclined as shown in FIG. 1, 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 lifted upward and stored in the fixed guide rail 2 from the state where the movable guide rail 1 is pulled out and tilted.

  In this operation, as shown in FIG. 1, the movable guide rail 1 is first pulled out and tilted, and then the engaging roller 1b of the movable guide rail 1 is moved to the horizontal guide portion 2ca of the guide portion 2c of the fixed guide rail 2. 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, the engagement roller 1b of the movable guide rail 1 is guided and moved by the tilting guide portion 2cb, and the buffer mechanism 3 of the guide portion 2c of the fixed guide rail 2 is integrated with the movable guide rail 1 to be a fixed guide. The front end of the rail 2 rotates around its front end. However, when a force for lifting the movable guide rail 1 is applied, the shock absorbing mechanism 3 engaged with the engaging means 1c of the movable guide rail 1 is applied. Reaction force of the shock absorber 3a transmitted through the engagement portion 3ba of the engaged means 3b (that is, a force generated when the piston rod 3aa of the shock absorber 3a is displaced in the protruding direction to return to the original position) ), The movable guide rail 1 can be lifted with a smaller force.

  Further, at this time, the shock absorber 3a may be used in a case where a person who performs the operation lifts the movable guide rail 1 upward vigorously from the state in which the movable guide rail 1 is pulled out and tilted, or in winter when the outside temperature is low. As the viscosity of the oil, which is an incompressible fluid, increases, the reaction force weakens, and the moving speed when the piston 3a of the shock absorber 3a is displaced in the protruding direction to return to the original position decreases. Due to various factors such as the case of the jamming, the biston rod of the shock absorber 3a is displaced by the reaction force and the moving guide rail from the contact point of the movable guide rail 1 and the support roller 2a rather than the moving speed when returning to the original position. Since the moving speed when the one engaging means 1c moves away is increased, the respective engagement receiving portions 1caa, 1caa of the two engaging pieces 1ca, 1ca of the engaging means 1c of the movable guide rail 1 are obtained. And shock absorber 3 Even if the engaged portion 3b is disengaged from the engaging portion 3ba, the auxiliary portion 3bb of the buffer mechanism 3 is connected to the auxiliary pieces 1cb of the engaging means 1c of the movable guide rail 1 as shown in FIG. By being held by 1cb, the phenomenon that the shock absorber 3a rotates at once at the front end portion in the fixed guide rail 2 around the front end and falls to the bottom portion in the fixed guide rail 2 is prevented.

  In this way, the engagement receiving portions 1caa, 1caa of the engaging pieces 1ca, 1ca of the engaging means 1c of the movable guide rail 1 and the engaging portion 3ba of the engaged means 3b of the buffer mechanism 3 are related to each other. When the force that lifts the movable guide rail 1 upward is weakened or released in the state where the joint is disengaged, the piston rod 3aa of the shock absorber 3a of the shock absorber 3 is projected by the reaction force during that time. It is possible to return to the engaged state again.

Finally, it comprises an engaging roller 1b of the movable guide rail 1 is positioned near the front end of the horizontal guiding portion 2ca of the guide portion 2c of the fixed guide rail 2 movable guide rail 1 as shown in FIG. 4 and a substantially horizontal state After that, if the movable guide rail 1 is further pushed backward, the movable guide rail 1 can be accommodated in the fixed guide rail 2.

  At this time, a state where a slight gap is provided between the fixed guide rail 2 and the outer surface of the movable guide rail 1 at a position above the support roller 2b and facing each outer surface of the movable guide rail 1 The sound deadening member 5 made of an elastic body is fixed to each other, and each sound deadening facing the movable guide rail 1 at the position facing the sound deadening member 5 when the movable guide rail 1 is positioned at the rearmost side. If the pair of leaf springs 6 and 6 slightly protruding in the direction of the member 5 are fixed, the rear end portion of the movable guide rail 1 is fixed guide when the movable guide rail 1 is stored in the fixed guide rail 2. Not only is it possible to prevent a collision noise from being generated by vigorously colliding with the rear end side of the rail 2, but it is preferable that the movable guide rail 1 be moved when the movable guide rail 1 is moved. Since it is possible to prevent the shake in the listening left, it is possible to perform movement relative to the stationary guide rail 2 of the movable guide rail 1 stably.
