Description

  The present invention relates to a bicycle parking machine capable of vertically moving up and down by loading a bicycle and an automatic return device used therefor.

The two-stage bicycle parking machine has a storage capacity that is twice that of flat placement, so it can effectively use a small space. For this reason, it is widely used mainly in station bicycle parking lots and suburban bicycle parking lots in the suburbs of large cities. A bicycle parking device that parks a bicycle in two stages, upper and lower, is movable at a predetermined height from the floor, with the fixed frame supported substantially horizontally in the front-rear direction, and moving forward and backward along the fixed frame. Place the bicycle to be parked by rotating it downward with the frame pulled out to the rear end side of the fixed frame, rotate the movable frame carrying this bicycle upward almost horizontally, Many types are used that are pushed in to the front end side and house the bicycle on the upper side. On the other hand, there is also known a vertical elevating bicycle parking machine that can raise and lower a bicycle rack vertically (see, for example, Patent Document 1). In such a system, a movable frame on which a bicycle is loaded is pulled out horizontally and slanted. It is useful because it requires less work space compared to the above-mentioned bicycle parking machine that raises and lowers the speed. These bicycle parking machines often use a plurality of machines arranged in parallel.

  However, in the vertical lift type bicycle parking machine, the bicycle rack (base) is always in the upper position, regardless of whether the bicycle is loaded or not, except when the bicycle is loaded and unloaded. It is a use condition to keep. This is because there is a type in which the slide rack does not move if the rack remains down. In addition, when a bicycle placed under a vertical lift type bicycle parking machine is loaded on a rack with wheels or rails for moving in the lateral direction of the bicycle and the rack to be raised upward is lowered by the vertical lift type bicycle parking machine. In many cases, it can be moved left and right so as not to get in the way. However, after pulling out the bicycle from the rack, there are people who leave without lifting the rack, and as it is, the movement of the bicycle arranged below is restricted, which hinders the use of nearby bicycle parking machines installed in parallel. There is confusion.

The switching unit 100 is attached to the lower part of the rack 400, and the second slider 200 is engaged with the lower part of the switching unit 100 to be integrated (in FIG. The state separated from 100) is illustrated for explaining the positional relationship.

  This will be described in detail with reference to FIGS.

  As shown in FIG. 1, at the front end of the rack 400, a first slider 500 having a light load spring 510 suspended upward along with the rack 400 fixed to the upper part is detachably attached. The first slider 500 has tires on both sides, and the tire can roll up and down the first slider 500 smoothly by rolling on the wall surface of the column 300. The light load spring 510 is integrated with the switching unit 100 attached to the lower part of the rack 400 provided with the first slider 500. The light load spring 510 is wound around the first winder 520 and stored at the uppermost portion of the support column 300. The light load spring 510 always acts as a pulling force in the upward direction, and is a first lifting means that pulls the rack 400 above the column 300 and moves it up and down along the column 300.

  The first elevating means and the second elevating means that pull the rack up and down along the support column are preferably springs that always pull the rack upward above the support column. More preferably, the spring is a constant load spring that can always be pulled and returned with a constant force. Since the output is always constant regardless of the stroke amount, the rack can be raised and lowered smoothly.

  The light load spring 510 is a constant load spring having a load of 110% to 120% of the total weight of the weight of the first slider 500, the weight of the switching unit 100, the weight of the rack 400 and its accessories. When the rack 400 is at the position of the third stopper portion 330, the winding is finished and no further pulling is performed. At the uppermost part of the support column 300, shock absorbing rubber 340 is provided on both sides of the light load spring 510 to reduce the impact when the first slider 500 is raised. In FIG. 1, the rack 400 is in a state where the first stopper plate 111 is locked at the position of the third stopper portion 330 without loading a bicycle.

  The heavy load spring 610 includes a weight obtained by adding 16 kg to 20 kg to a weight obtained by adding the weight of the first slider 500, the weight of the second slider 200, the weight of the switching unit 100 and the weight of the rack 400 and its accessories. It is a constant load spring. When the first stopper plate 111 is at the position of the third stopper portion 330, the heavy load spring 610 has finished winding and no longer pulls upward. A bicycle normally has a load of 20 kg or less, and the heavy load spring 610 allows the user to raise the rack 400 with little force even when the bicycle is loaded on the rack 400.

  As shown in FIG. 4, the second slider 200 positioned below the column 300 in FIG. 1 has a wire 640 fixed and connected at the front end thereof. The second slider 200 has tires on both sides, and the tire can roll up and down the second slider 200 smoothly by rolling on the wall surface of the column 300. The second slider 200 can be engaged with and disengaged from the lower front portion of the switching unit 100. A portion where the second slider 200 is integrated corresponds to a lower portion of the box 140 of the switching unit 100. When the second slider 200 is locked to and integrated with the switching unit 100, the rack 400 has a wire 640 connected to the second slider 200 below the front end.

  The wire 640 is suspended from a pulley 630 located in the middle of the column 300, that is, near the lower portion of the third stopper portion 330. A heavy load spring 610 connected to the other end of the wire 640 whose tip is connected to the second slider 200 is wound around the second winder 620 and stored in the lower portion of the support 300. The heavy load spring 610 always has a pulling force. Therefore, when 200 is locked to and integrated with the switching unit 100, the heavy load spring 610 serves as a second lifting unit that pulls the rack 400 above the column 300 and moves it up and down along the column 300.

  Below the support column 300, a first stopper portion 310 having a triangular wedge shape having a flat bottom and a smooth top surface is provided. The first stopper portion 310 has the switching unit 100 having the first stopper plate 111 at the bottom and is always pulled upward by the light load spring 510 by fixing the first stopper plate 111 below the first stopper portion 310. The rack 400 can be prevented from rising upward.

  Below the support column 300, a second stopper portion 320 having a wedge shape having a triangular shape in a side view with a flat bottom portion and a smooth inclined top portion is provided below the first stopper portion 310. The second stopper 320 fixes the second stopper plate 210 below the second stopper 320 so that the second slider 200 having the second stopper plate 210 is provided at the bottom and is always pulled upward by the heavy load spring 610. The second slider 200 can be prevented from rising upward.

  Above the support column 300, a third stopper portion 330 having a wedge shape with an inverted triangular side view having a flat inclined ceiling portion and a smooth lower surface is provided directly above the first stopper portion 310. The third stopper portion 330 fixes the first stopper plate 111 above the third stopper portion 330 so that the rack 400 having the switching unit 100 having the first stopper plate 111 at the lower portion is empty even when the bicycle is loaded. You can prevent the weight from dropping even at times.

  The second stopper part 320 is provided not on the first stopper part 310 but on the right side as shown in FIG. Since the third stopper portion 330 is provided directly above the first stopper portion 310, the third stopper portion 330 is obliquely upper left of the second stopper portion 320.

  As shown in FIG. 2, the switching unit 100 is provided with a lot plate 121 and a first stopper plate 111 slidable side by side.

  As shown in FIG. 3, the seesaw 123 has a semicircular ring shape, that is, an arcuate shape, is provided in front of the rack 400 in a state of protruding from the bottom of the rack 400 to the bicycle loading surface, and the bicycle wheel loaded on the rack 400. Rolls in the circumferential direction by fitting and removing.

  A connector 126 is connected to the bottom of the seesaw 123. As the seesaw 123 rolls, the position of the connector 126 moves rearward when the bicycle is loaded and forward when the passenger gets off. In addition, a seesaw lot 124 connected to the seesaw 123 via a coupling tool 126 extends toward the front end of the rack 400 at the bottom of the rack 400. The seesaw lot 124 moves in the front-rear direction of the rack 400 according to the movement of the seesaw 123.

  As shown in FIG. 3, when the bicycle is not loaded on the rack 400, the seesaw 123 is convex on the front side of the rack 400, but when the bicycle is loaded and advanced forward, the wheels fit into the ring of the seesaw 123. Since the front is pushed, the seesaw 123 rolls to the rear of the rack 400 as the wheel moves forward. A coupling tool 126 is fixed on the periphery of the seesaw 123, and the seesaw lot 124 connected to the coupling tool 126 is pulled to the rear of the rack 400. Therefore, in conjunction with the movement of the seesaw 123, the lot plate 121 is pulled backward.

  On the other hand, when the bicycle is moved backward, the wheel rotates to the front side with the wheel fitted, and when the bicycle is further moved backward and lowered from the rack 400, the wheel is detached from the seesaw 123. A force is always applied to the lot plate 121 in the direction of pulling in the forward direction of the rack 400 by the second spring 125. The second spring 125 is a tension spring having one end connected to the rear of the lot plate 121 and the other end connected to a front portion of the box 140. A tension spring that is a tension spring is a spring that uses a force to return when it is stretched. A push spring may be used instead of the tension spring. In the case of a push spring, one end is connected to the lot plate 121 and the other end is connected to a portion of the box 140 behind the lot plate 121. A compression spring, which is a compression spring, is a spring that uses a force to return when compressed.

  Accordingly, when the bicycle is not on, the seesaw 123 is not pulled backward, so the lot plate 121 is pulled forward by the second spring 125. In conjunction with the lot plate 121, the seesaw 123 has a wheel. Fixed when removed. Therefore, when the bicycle is loaded next time, the wheel does not hit the edge of the seesaw 123 to prevent the loading, and the bicycle can be smoothly loaded and fitted to the seesaw 123.

  As shown in FIG. 2, the tip of the seesaw lot 124 is stored in a box 140 provided at the lower front end of the rack 400 together with the first stopper plate 111. Box 140 serves as a cover. In addition, a handle 114 is provided at the rear end of the rack 400 to be pulled and operated by the user.

  The tip of the lot plate 121 is in a steady state where no load is applied, that is, in a state where the bicycle is not fitted to the seesaw 123, and the end of the change plate 130 connected to the lot plate 121 is as shown in FIG. The end on the first stopper plate 111 side is in the rear direction of the rack 400 in the front direction of the rack 400. When the bicycle is loaded, the direction of the change plate 130 changes and does not overlap the lower side of the plate chip 112.

  As shown in FIG. 1, the manual handle 114 attached to the lower end of the rear end of the rack 400 is connected to one end of a manual lot 113 that moves in the front-rear direction of the rack 400 according to the movement of the handle 114. When a person pulls the handle 114, the manual lot 113 is pulled backward in the rack 400. The other end of the manual lot 113 is connected to the first stopper plate 111. A first spring 115 is connected to the first stopper plate 111, and a force acts in a direction in which the first spring 115 is always pulled out in the forward direction of the rack 400.

  In the present embodiment, the first spring 115 is a tension spring having one end connected to the rear of the first stopper plate 111 and the other end connected to the front portion of the box 140. A push spring may be used instead of the tension spring. In the case of a push spring, one end is connected to the first stopper plate 111 and the other end is connected to a portion of the box 140 behind the first stopper plate 111.

  The front end of the first stopper plate 111 protrudes forward from the front end of the rack 400 in a steady state. By pulling the handle 114, the manual lot 113 moves in the rearward direction of the rack 400, and accordingly, the first stopper plate 111 is pulled and moved in the rearward direction of the rack 400 and protrudes forward from the front end of the rack 400. The front end portion that has been retracted retracts toward the rear of the rack 400. When the hand that pulled the handle 114 is released, the first stopper plate 111 returns to the steady state by the first spring 115 and protrudes forward from the front end of the rack 400.

  The first stopper plate 111 is located on the left side when viewed from the top of the rack, and is locked to the first stopper portion 310 and the third stopper portion 330 in a state of protruding to the front side from the front end of the rack 400, and pulls the handle 114. , Unlocking with the protruding tip part retracted.

  On the other hand, the lot plate 121 is located on the right side when viewed from the top of the rack and does not protrude forward from the front end of the rack 400. When a bicycle is loaded on the rack 400, the seesaw lot 124 is pulled backward in conjunction with the movement of the seesaw 123, and the lot plate 121 also moves backward. As a result, the change plate 130 having one end fixed to the lot plate 121. , One end thereof moves backward as the lot plate 121 moves. The change plate 130 is also fixed at the fulcrum 132. The fulcrum 132 is fixed at a position between the lot plate 121 and the first stopper plate 111 so as to be vertically movable from the top plate of the box 140 by a support with a spring. Therefore, the change plate 130 rotates around the fulcrum 132, and the other end of the change plate 130 moves to the front end side of the rack 400. The direction of rotation at this time is counterclockwise toward the paper surface in FIG. As a result, the change plate 130 whose tip is overlapped with the lower side of the plate chip 112 (the front side in FIG. 2A) does not overlap the plate chip 112.

  The change plate 130 has a notch near the tip on the plate chip 112 side. The cutout portion is on the right side in FIG. This notch portion realizes that when the lot plate 121 moves backward, the change plate 130 does not overlap the plate chip 112 even if the rotation angle is slight.

  The first protrusion 122 protruding below the lot plate 121 acts when the second slider 200 is connected to and integrated with the lower part of the switching unit 100 and will be described later.

  The second slider 200 has a second protrusion 211 protruding upward on the right side as viewed from the back (right side as viewed in FIG. 4). When the second slider 200 is combined with the switching unit 100, the second protrusion 211 comes into contact with the lower surface of the tip of the change plate 130 on the first stopper plate 111 side, and the tip of the change plate 130 is viewed from below. Push up.

  The second slider 200 is slidably provided with a second stopper plate 210 on the left side as viewed from the back (left side as viewed in FIG. 4C). A third spring 212 is connected to the second stopper plate 210, and a force is always exerted by the third spring 212 in a direction of pushing the rack 400 forward.

  In the present embodiment, the third spring 212 is a tension spring having one end connected to the second stopper plate 210 and the other end connected to a portion of the second slider 200 in front of the second stopper plate 210.

  The distal end portion of the second stopper plate 210 projects forward from the front end of the rack 400 in a steady state. A third protrusion 220 is projected from the upper portion of the second stopper plate 210. The third projecting portion 220 is a portion that contacts the side surface of the first projecting portion 122 on the front side (the front side in FIG. 4) when the second slider 200 contacts the lower portion of the switching unit 100. is there.

  When the bicycle is loaded on the rack 400 and the lot plate 121 moves rearward, the first protrusion 122 also moves rearward, so that the third protrusion 220 that is in contact is pushed backward. When the third protrusion 220 moves rearward, the second stopper plate 210 on which the third protrusion 220 protrudes also moves rearward, and the tip of the second stopper plate 210 has the switching unit 100 attached. The front end protruding from the front end of the rack 400 is retracted to the rear of the rack 400. In a state where the first protrusion 122 contacts the third protrusion 220 and pushes the third protrusion 220 rearward, the first protrusion 122 and the third protrusion 220 are pressed against each other, and the switching unit 100 is pressed. The second slider 200 moves up and down while being united. When the lot plate 121 returns to the steady state position, the second stopper plate 210 returns to the steady state by the third spring 212 and protrudes forward from the front end of the rack 400. In this state, the contact between the first protrusion 122 and the third protrusion 220 is weak, and the second slider 200 is separated from the switching unit 100 and does not move up and down. That is, the third protrusion 220 contacts the first protrusion 122 when the second slider 200 contacts the lower portion of the switching unit 100 to control engagement / disengagement with the switching unit 100 and the second stopper plate 210. To move the rack 400 in the front-rear direction of the rack 400.

  The second stopper plate 210 is locked to the second stopper portion 320 in a state of protruding forward from the front end of the rack 400, and the protruding tip portion is in a state where the third protrusion 220 is in pressure contact with the first protrusion 122.

When the bicycle is alighted, the first stopper plate 111 is prevented from being locked to the first stopper portion 310 and unlocked even when the handle 114 is not pulled, allowing the rack 400 to be raised and lowered.

  Hereinafter, the operation will be described in detail for each stage.

(First state: The rack position is in the upper row and empty)
FIG. 6 is an explanatory diagram of the first state of the bicycle parking machine according to the first embodiment of the present invention. The shaded area indicates the locked state. 6 to 12, 14, and 15, the internal structures of the switching unit 100 and the second slider 200 are also illustrated in a slightly enlarged manner for the sake of explanation. Actually, when the rack 400 is in the lower stage, the rack 400 is located near the floor surface, and the bicycle can be easily put on and off. When the vehicle is empty, the second stopper plate 210 protrudes forward by the third spring 212. This is the steady state of the second stopper plate 210. The second stopper plate 210 is locked to the second stopper portion 320. The first stopper plate 111 protrudes forward by the first spring 115. This is the steady state of the first stopper plate 111. The first stopper plate 111 is locked to the third stopper portion 330. The upper stage is the position of the third stopper part 330, and the lower stage is the position of the first stopper part 310. Since the lower portion is held at the position of the third stopper portion 330 by the first stopper plate 111, the rack 400 does not descend. At this time, the tip of the plate chip 112 is lowered by its own weight. The change plate 130 is below the plate chip 112.

  In the first state, when the handle 114 is pulled by the user, the first stopper plate 111 is pulled backward through the manual lot 113 and unlocked from the third stopper portion 330. Although force is working upward by the first slider 500, it is lowered by its own weight when lightly pressed down. When it is lowered below the third stopper portion 330, the handle 114 is released. When the handle 114 is released, the first stopper plate 111 protrudes to the front side of the rack 400 by the first spring 115.

  The rack 400 is lightly pushed down and lowered until the first stopper plate 111 comes under the first stopper portion 310. In the wedge-shaped inclined portion of the first stopper portion 310, the first stopper plate 111 hitting the inclined portion gradually pushes back the first spring 115 to slide down the rack 400.

(Second state: Rack position is lower and empty)
FIG. 7 is an explanatory diagram of the second state of the bicycle parking machine according to the first embodiment of the present invention. The shaded area indicates the locked state. When the rack is lowered as it is from the first state, when the first stopper plate 111 comes under the first stopper portion 310, the first stopper plate 111 protrudes forward by the first spring 115, and the first stopper portion 310 is locked.

  The change plate 130 comes into contact with the second protrusion 211 and is pressed from below. The plate chip 112 lowered by its own weight is pushed from below by the change plate 130 and is sandwiched between the first stopper plate 111 and the change plate 130. The first stopper plate 111 is the first stopper portion 310, and the second stopper plate 210 is also the second stopper portion 320, and the upward movement is restricted. Since the bicycle is not loaded, the lot plate 121 does not move in the rearward direction of the rack 400, and therefore the third protrusion 220 is not pressed by the first protrusion 122. Therefore, although the switching unit 100 and the second slider 200 overlap vertically, they are not locked together.

(Third state: The rack position is rising from the bottom and is empty)
FIG. 8 is an explanatory diagram of a third state of the bicycle parking machine according to the first embodiment of the present invention. When the user pulls the handle 114 while the vehicle is empty from the second state, the first stopper plate 111 moves in the rearward direction of the rack 400, is unlocked from the first stopper portion 310, and is connected to the light load spring 510. It is pulled up by the slider 500 and rises at a substantially constant speed. In the second state, the second slider 200 is under the switching unit 100, but the third protrusion 220 is not pressed by the first protrusion 122, and the second stopper plate 210 does not rise as a unit. The second stopper portion 320 remains locked.

(Fourth state: Rack position at the bottom and bicycle loaded)
FIG. 9 is an explanatory diagram of a fourth state of the bicycle parking machine according to the first embodiment of the present invention. The shaded area indicates the locked state. When the bicycle 700 is loaded on the rack 400 from the second state, the seesaw lot 124 is pulled to the rear side of the rack 400 (the right side in FIG. 9) as the seesaw 123 moves, and the lot plate 121 moves to the rear side of the rack 400. Along with this, the change plate 130 rotates around the fulcrum 132. The direction of rotation is counterclockwise toward the paper surface in FIG. Then, the plate chip 112 sandwiched between the first stopper plate 111 and the change plate 130 in the second state is disengaged from the lower part of the plate chip 112 and the front side of the rack 400 (the left direction in FIG. 9). ), The tip of the plate tip 112 is lowered by its own weight. The lower surface of the tip of the change plate 130 is pushed up from below by the second protrusion 211 even in the fourth state. The lower surface of the tip of the plate chip 112 and the lower surface of the change plate 130 have the same height.

  As the lot plate 121 moves backward, the first protrusion 122 also moves backward. The first projecting portion 122 pushes the third projecting portion 220 to the rear side of the rack 400 (to the right in FIG. 9). When the third protrusion 220 moves to the rear side of the rack 400, the second stopper plate 210 that fixes the third protrusion 220 to the upper part also moves to the rear side of the rack 400 and is unlocked from the second stopper part 320. . Further, the first projecting portion 122 and the third projecting portion 220 are in pressure contact with each other, and the switching unit 100 and the second slider 200 are engaged with each other and united.

(Fifth state: The rack position is the state where the bicycle is loaded at the bottom and the handle is pulled)
FIG. 10 is an explanatory diagram of the fifth state of the bicycle parking machine according to the first embodiment of the present invention. When the handle 114 is pulled from the fourth state, the first stopper plate 111 moves to the rear side of the rack 400 through the manual lot 113 and is unlocked from the first stopper portion 310. Since the bicycle 700 is loaded, the first protrusion 122 remains in pressure contact with the third protrusion 220, and thus the second stopper plate 210 also moves to the rear side of the rack 400, and the second stopper portion. It remains unlocked from 320. Even in the fifth state, the lower surface of the tip of the change plate 130 is pushed up from below by the second protrusion 211, so the lower surface of the tip of the plate chip 112 and the lower surface of the change plate 130 remain at the same height.

(Sixth state: The rack position is rising from the bottom and the bicycle is being loaded)
From the fifth state, the rack 400 rises at a substantially constant speed. A light load spring 510 connected to the rack 400 via the first slider 500 and a heavy load spring 610 connected to the second slider 200 integrated with the switching unit 100 below the rack 400 via a wire 640. The rack 400 is pulled up and raised. Even if the bicycle 700 is loaded by the heavy load spring 610, the rack 400 moves up. The handle 114 may be released when the first stopper plate 111 rises above the first stopper portion 310. The first stopper plate 111 protrudes forward by the first spring 115 when the handle 114 is released. The first stopper plate 111 is raised until it comes over the third stopper portion 330. In the wedge-shaped inclined portion of the third stopper portion 330, the first stopper plate 111 hitting the inclined portion slides up the rack 400 while gradually extending the first spring 115.

(Seventh state: The rack position is in the upper row and the bicycle is loaded)
FIG. 11 is an explanatory diagram of a seventh state of the bicycle parking machine according to the first embodiment of the present invention. The shaded area indicates the locked state. When the rack is lifted as it is from the sixth state and the first stopper plate 111 reaches the top of the third stopper portion 330, the first stopper plate 111 protrudes forward by the first spring 115, and the third stopper portion 330 is reached. Locked to.

  In addition, since the bicycle 700 is loaded in the seventh state, the first protrusion 122 remains in pressure contact with the third protrusion 220, and thus the second stopper plate 210 has also moved to the rear side of the rack 400. The switching unit 100 and the second slider 200 remain united. Even in the seventh state, the lower surface of the tip of the change plate 130 is pushed up from below by the second protrusion 211, so the lower surface of the tip of the plate chip 112 and the lower surface of the change plate 130 remain at the same height. Further, since the first stopper plate 111 moves in the direction of protruding forward, the tip of the plate chip 112 comes into contact with the tip side surface of the change plate 130 so as to push the rack 400 forward.

  When the handle 114 is pulled from the seventh state, the first stopper plate 111 moves to the rear side of the rack 400 and the first stopper plate 111 is unlocked from the third stopper portion 330.

  The rack 400 is lightly pushed down and lowered until the first stopper plate 111 comes under the first stopper portion 310. In the wedge-shaped inclined portion of the first stopper portion 310, the first stopper plate 111 hitting the inclined portion gradually pushes back the first spring 115 to slide down the rack 400.

(Eighth state: The rack position is at the bottom and the state when the bicycle gets off)
FIG. 12 is an explanatory diagram of an eighth state of the bicycle parking machine according to the first embodiment of the present invention. FIG. 13 is a schematic bottom view of the front portion of the switching unit in the eighth state of the bicycle parking apparatus according to the first embodiment of the present invention. When the rack 400 is lowered from the seventh state and the bicycle 700 is lowered, the seesaw lot 124 is pulled to the front side of the rack 400 (left side in FIG. 12) as the seesaw 123 moves, and the lot plate 121 is moved to the front side of the rack 400. Move to. Accordingly, the change plate 130 having one end fixed to the lot plate 121 rotates about the fulcrum 132. The direction of rotation is clockwise toward the paper surface in FIG. By rotation, the tip that is not fixed to the lot plate 121, that is, the tip on the plate chip 112 side, moves backward in the rack 400. As a result, the tip of the plate chip 112 is pushed in the rearward direction of the rack 400 by the tip side surface of the rotated change plate 130 and is in a pressure contact state.

  Even in the eighth state, the lower surface of the change plate 130 is pushed up from below by the second protrusion 211, so that the lower surface of the tip of the plate chip 112 and the lower surface of the change plate 130 remain at the same height. 112 is not sandwiched between the first stopper plate 111 and the change plate 130.

  Therefore, even if a force is applied to the first stopper plate 111 to move forward of the rack 400 by the first spring 115, the plate chip 112 having one end on the rear side of the rack 400 fixed to the lower surface of the first stopper plate 111 is changed to the change plate. Since the movement to the front of the rack 400 is prevented by 130, the first stopper plate 111 cannot move in the forward direction of the rack 400 and cannot be locked to the first stopper portion 310.

  When the bicycle 700 is lowered from the rack 400, the lot plate 121 moves to the front side of the rack 400, so that the first protrusion 122 also moves to the front side of the rack 400. Accordingly, in the seventh state, the third protrusion 220 that has been pushed to the rear side of the rack 400 by the first protrusion 122 moves in the forward direction of the rack 400 by the third spring 212 in the eighth state. Therefore, the second stopper plate 210 moves to the rack 400 front side. Therefore, the second stopper plate 210 is locked to the second stopper portion 320 at the same time as the bicycle 700 is lowered.

(Ninth state: Rack position at the start of ascent from the bottom and after getting off the bicycle)
FIG. 14 is an explanatory diagram of the ninth state of the first embodiment of the bicycle parking machine of the present invention. When getting off in the eighth state, the second stopper plate 210 is locked to the second stopper portion 320, while the first stopper plate 111 is not locked to the first stopper portion 310, so when the bicycle is lowered, from the eighth state, The rack 400 having the box 140 at the bottom is pulled up by the first slider 500 and starts to rise automatically. The second slider 200 is separated from the switching unit 100 and is held at the position of the second stopper portion 320.

  When the switching unit 100 and the second slider 200 are separated, the change plate 130 is lowered below the tip of the plate chip 112 and is separated from the plate chip 112 while the rack 400 is raised.

(Tenth state: The rack position is rising from the lower stage and the state after the bicycle is dismounted)
FIG. 15 is an explanatory diagram of a tenth state of the bicycle parking machine according to the first embodiment of the present invention. While continuing to rise from the ninth state, the plate tip 112 slides between the first stopper plate 111 and the change plate 130. As a result, the first stopper plate 111 can move to the front side of the rack 400, and the first stopper plate 111 protrudes forward by the first spring 115. The first stopper plate 111 is automatically raised until it comes over the third stopper portion 330. In the wedge-shaped inclined portion of the third stopper portion 330, the first stopper plate 111 hitting the inclined portion gradually pushes back the first spring 115 and slides the rack 400 up.

  When the first stopper plate 111 reaches the top of the third stopper portion 330, the first stopper plate 111 protrudes forward by the first spring 115 and is locked to the third stopper portion 330, and is the same as in the first state. It becomes a state.

  As described above, the switching unit 100 and the second slider 200 control whether the rack 400 is raised or lowered, and automatically raises the rack 400 to the upper stage when the bicycle is dismounted from the rack 400 in the lower stage. .

{effect}
Since the present embodiment has such a configuration, it is possible to automatically lift the empty rack by lowering the bicycle from the rack.

  According to this embodiment, when the empty rack is lowered to place the bicycle on the rack, the second stopper plate is locked to the second stopper portion, and the first stopper plate is locked to the first stopper portion. Therefore, the bicycle can be safely loaded without lifting the rack automatically, and when the bicycle is lowered from the rack, the second stopper plate is locked to the second stopper portion, and the first stopper plate is the first stopper portion. Since the rack is unlocked, the empty rack can be automatically lifted, and there is no need for a person to lift the empty rack. Therefore, it is possible to prevent a state in which the rack remains down after the bicycle is lowered from the rack. When the rack is empty, the rack can be kept in the upper state except when the rack is pulled down in an empty state. .

  Moreover, the movement of the bicycle arranged below is not restricted, and it is possible to prevent complaints and troubles when used by an unspecified number of people.

  Furthermore, the rack pulled up automatically is safe because the first stopper plate is locked to the third stopper portion and automatically held above the support column and does not fall. Also, when the bicycle is loaded and the rack is lifted, it will not rise unless manual operation is performed, so the rack does not move suddenly when the bicycle is loaded, and the first stopper plate is the third stopper section. It is safe because it is locked and automatically held above the column and does not fall.

  According to the present embodiment, depending on whether the bicycle was lowered from the rack above the support column or the bicycle was lowered while the bicycle was loaded, the rise in the same empty state lowered the rack below the support column. Later movements are different. When the bicycle is lowered by an empty vehicle, the rack is not lifted unless it is locked and pulled down and pulled by a handle. However, if the bicycle is lowered while the bicycle is loaded and the bicycle is unloaded, the rack is automatically raised.

  Even if there is a person who leaves without lifting the rack after the bicycle is pulled out, according to the present embodiment, the rack is automatically raised, so that troubles and breakdowns between users can be prevented.

  It should be noted that the present invention is not limited to the above-described embodiment described with reference to examples, and various modifications can be made without departing from the spirit of the invention.
