Description

  The present invention relates to a bicycle parking machine that can be applied to an upper and lower two-stage type, and a bicycle parking lot in which a plurality of such bicycle parking machines are installed.

  The bicycle parking machine disclosed in Patent Document 1 increases the number of parked bicycles by using two upper and lower stages, and automatically returns a rack in an empty state by lowering the bicycle and automatically returning the rack ( Auto return structure). In addition, the bicycle parking machine disclosed in Patent Document 2 is assisted by an air cylinder when a user performs a raising / lowering operation of a rack (including a lifting platform) (assist raising / lowering), and the assisting force (lifting assisting force) is switched. The valve can be switched between an actual vehicle state (a state where a bicycle is placed) and an empty vehicle state (a state where the bicycle is lowered) (assist force in an empty vehicle state is almost 0).

  According to Patent Document 1, the user can automatically return to the upper standby state without performing a lifting operation of the rack after use (in an empty state). However, since only the rack raising in the empty vehicle state is automated, the rack lowering and the rack raising in the actual vehicle state still require the user's own operation. On the other hand, according to Patent Document 2, the assist force acts in the actual vehicle state, and the burden on the user is reduced. However, the main body of the lifting operation is the user, and the air cylinder is only an auxiliary means, and especially the assist force in the empty state is almost zero, so the burden on the user (relieving the burden of assist force adjustment) Aside from the previous).

  As described above, even if the operation force is partially reduced in Patent Documents 1 and 2, the user still needs an operation force (arm force) for raising and lowering the rack. Therefore, the disadvantageous situation is not improved particularly in the case of a user who is inferior in physical strength such as a child, an elderly person, or a woman, or when handling a heavy bicycle such as a bicycle with an electric assist.

Japanese Patent No. 4265692 JP 2007-138680 A

  An object of the present invention is to provide a bicycle parking machine capable of reducing the burden on the user and improving the operability by reducing the burden on the user in the entire process of raising and lowering the rack regardless of the actual vehicle state or the empty vehicle state. It is to provide a bicycle parking lot equipped with various bicycle parking machines.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the bicycle parking apparatus of the present invention
A slider having a rack on which a bicycle can be mounted, and a slider that moves up and down in an actual vehicle state in which the bicycle is mounted on the rack or an empty vehicle state in which the bicycle is not mounted, along a support column erected in the vertical direction;
An air cylinder that is disposed on the support and has a piston rod that reciprocates in the vertical direction and moves the slider up and down by the operation of the piston rod;
An air pressure control circuit for controlling the piston rod of the air cylinder by air pressure, including a switching valve for switching a driving direction of the piston rod to raise or lower the slider;
An operation means that is artificially operated to switch the switching valve;
The switching valve is controlled directly by operation of the operation means or indirectly through auxiliary means operated by operation of the operation means, and an ascending-side control circuit for raising the slider in the air pressure control circuit; And a lower side control circuit for lowering the slider.

  As described above, when the user operates the operating means (for example, the operating lever), the switching valve switches the operating direction of the piston rod of the air cylinder so that the rack (including the slider) moves up and down (automatic lifting of the rack). ). Therefore, no operation force is required for the rack in the entire process of raising and lowering the rack regardless of the actual vehicle state and the empty vehicle state, and the user attaches his / her hand to the operating means and slider (or rack) to ensure safety when the rack is raised and lowered. Therefore, the burden on the user is greatly reduced and the operability is greatly improved. As a result, it is possible to eliminate restrictions (restrictions) on the use of bicycle parking machines in terms of user age / sex, weight of bicycle, etc., and to further contribute to the spread of bicycle parking machines.

  In addition, by using air pressure as the drive source for raising and lowering the rack (slider), it is possible to cope with a large weight difference between an empty vehicle state (for example, 5 kg weight or less) and an actual vehicle state (for example, 15 kg weight or more), and the elasticity of compressed air Due to the cushioning (cushion) action based on the above, safety during elevation is high. Further, since discharge into the atmosphere and leakage are allowed, the pneumatic control circuit and the switching valve can be simplified.

  In addition, the operation means controls the switching valve directly or indirectly through the auxiliary means, and widely selects the location and installation form of the switching valve according to the configuration of the operation means and auxiliary means. As a result, the degree of freedom in design and construction is increased, and the versatility of the bicycle parking machine installation status, and consequently the size and layout of the bicycle parking lot, can be improved and contribute to bicycle parking countermeasures. For example, in the case where the operating means is an operating piece attached to the switching valve and directly operating the switching valve, the switching valve is fixed to a structure such as a wall member or a column member that forms a bicycle parking facility (bicycle parking lot) or It can be placed in a holding state. On the other hand, when the operating means is an operating lever installed on a rack or a slider, and the switching valve is operated indirectly via an auxiliary control circuit (pilot circuit) as auxiliary means, the switching valve is connected to an air cylinder or a column. Can be placed in a fixed state. In addition to the above-described auxiliary control circuit (for example, pilot circuit) or auxiliary switching valve (for example, pilot valve), the auxiliary means may be a remote control signal (for example, bidirectional) when the operation means is an operation switch of a remote control (remote controller). Communication equipment).

In the bicycle parking machine, the switching valve is installed in a fixed state on the air cylinder or the column, and the operation means is installed on the rack or the slider ,
The auxiliary means is an auxiliary control circuit branched from the pneumatic control circuit and connected in parallel. The auxiliary control circuit switches the switching valve to the ascending side control circuit or the descending side control circuit according to the operation of the operating means. May be activated.

When the user operates the operating means at hand (for example , pushes and pulls the operating lever ), the switching valve is switched via the auxiliary control circuit as the auxiliary means, and the rack (slider) is moved up and down. The rack can be raised and lowered easily regardless of whether it is in a state or an empty state. At the cylinder stroke end, the rack is maintained at the upper limit position or the lower limit position by continuous supply of air pressure and exhaust to the atmosphere.

Specifically, the auxiliary control circuit the auxiliary switching valve is installed in a fixed state to the rack or the slider,
By the pilot pressure mechanically actuates the auxiliary switching valve by operating the operation means, perating the Came ra switch to the ascending side control circuit switching valve and lowering side control circuit.

In this way, the user can indirectly switch the switching valve between the ascending side control circuit and the descending side control circuit by operating the operation means to operate the auxiliary switching valve. At that time, sometimes single auxiliary switching valve installed in a rack or the slider (e.g., the pilot valve) is shared into the rising side control circuit and a lowering side control circuit, it is possible to simplify the pneumatic control circuit . Also, indirectly sometimes alternately switching switching (rising → down or down → up) of the lift operation in or descending in rising elevator stopped the lowering side control circuit and the rising side control circuit by a single auxiliary switching valve It is possible without going through.

Alternatively , the auxiliary control circuit includes an upper auxiliary switching valve installed at the upper part of the column and a lower auxiliary switching valve installed at the lower part of the column,
The operating means mechanically operates the lower auxiliary switching valve at the lower part of the column and switches the switching valve to the ascending control circuit by the pilot pressure, while mechanically operating the upper auxiliary switching valve at the upper part of the column. The switching valve is switched to the descending control circuit by pressure.

  The switching valve is installed on the air cylinder or the column, and the two upper and lower auxiliary switching valves (for example, pilot valves) are installed on the column. Therefore, the pneumatic control circuit (ascending side control circuit and descending side control circuit) is always installed in the column. Can be fixed in place. In this way, the pneumatic control circuit is separated from the slider or rack that moves up and down (in an irrelevant position), and the pneumatic control circuit does not expand or contract even if the slider (rack) moves up and down. Air pressure control circuit can be simply piped.

  When the switching valve is an electromagnetic switching valve fixed to the air cylinder or the column, the operating means is a remote control switch, and the auxiliary means is a control signal that is activated by operating the remote control switch, the electromagnetic switching valve Is indirectly controlled via a control signal that is operated by operating a remote control switch, and is switched to an ascending control circuit for raising the slider and a descending control circuit for lowering the slider in the pneumatic control circuit.

In the bicycle parking apparatus, the operating means is an operating piece attached to the switching valve for mechanically switching the switching valve,
The switching valve is installed in a fixed state or a holding state on a structure such as a wall material or a pillar material constituting a bicycle parking facility, and may be switched to an ascending side control circuit or a descending side control circuit according to the operation of the operation piece. .

  As described above, the switching valve is installed in the structure (wall material, pillar material, etc.) of the bicycle parking facility, and the operation piece (for example, the operation plate) is disposed in the vicinity of the switching valve. The control circuit can be quickly switched by the operation piece, and the switching state can be displayed on the operation piece itself.

  Specifically, the switching valve is composed of an ascending-side switching valve disposed in the ascending-side control circuit and a descending-side switching valve disposed in the descending-side control circuit, and increases every time the operation piece is operated. The side switching valve alternately switches between a state in which the ascending side control circuit is operated and a state in which the descending side switching valve operates the descending side control circuit.

  In this way, since the ascending side control circuit and the descending side control circuit are directly switched alternately by the two switching valves, the switching of the raising / lowering operation during ascending or descending (ascending → descending or descending → ascending) It is possible without going through. At that time, the air pressure control circuit (ascending control circuit and descending control circuit) does not include an auxiliary switching valve (for example, a pilot valve), and the response when switching the lifting operation is fast and stable. Avoidance can be done quickly.

Alternatively, a closing valve common to the ascending side control circuit and the descending side control circuit is connected in series with the switching valve in the pneumatic control circuit,
The shut-off valve opens and closes the pneumatic control circuit regardless of the switching of the switching valve based on the operation of the operation piece.

  In this way, a stop valve that opens and closes the pneumatic control circuit (stop valve) is connected in series with the switching valve, so that it temporarily stops in the middle of raising and lowering by the switching valve, or continuously moves in the same direction after being temporarily stopped, It is possible to move back in the reverse direction.

  In these bicycle parking machines, the piston rod and the slider of the air cylinder may be coupled via a linkage mechanism including a moving pulley supported at the tip of the piston rod.

  As described above, by using the linkage mechanism including the moving pulley, the vertical movement stroke of the slider (or rack) becomes an integral multiple (for example, twice) of the vertical movement stroke of the piston rod. Thus, the amount of movement of the slider (or rack) can be increased.

And in order to solve the said subject, the bicycle parking lot of this invention is
A plurality of the above-mentioned bicycle parking machines are installed,
An air pressure control circuit for driving and controlling the piston rod of each air cylinder is connected in parallel to an air supply line from an air supply source.

  This makes it possible to adjust the number of installed bicycle parking machines (that is, the number of connected pneumatic control circuits) according to the size of the bicycle parking lot, and it is easy to increase the number of bicycle parking machines as the number of users increases. Can provide a bicycle parking lot that is convenient for the user.

  In the above bicycle parking lot, an on-off valve is provided at each branch point from the air supply pipe to each pneumatic control circuit, and the on-off valve is individually opened and closed in linkage with a toll collection system that centrally manages these multiple bicycle parking machines. May work.

  In this way, the on-off valve is linked to the toll collection system and individually opens and closes.For example, when a bicycle parking lot is managed and operated as a public facility, collection of maintenance fees, maintenance / inspection / repair, etc., is smooth. Can be done.

Example 1
Hereinafter, embodiments of the present invention will be described with reference to examples shown in the drawings. FIG. 1 is an overall front view when a rack is in a stopped state at an upper position as a first example of the bicycle parking apparatus of the present invention, and FIG. 2 is an overall front view when the rack is in a stopped state at a lower position. 1 and 2 includes a slider 10 to which a horizontal rack 11 on which a bicycle BCL can be mounted is fixed integrally. The slider 10 is erected in the vertical direction (vertical direction) regardless of whether it is in an actual vehicle state (a state where the bicycle BCL is mounted on the rack 11) or an empty vehicle state (a state where the bicycle BCL is not mounted on the rack 11). It can be raised or lowered along the supporting column 12. Note that the present invention can be applied to a vertical elevating bicycle parking apparatus having two upper and lower racks (see, for example, Japanese Patent Application Laid-Open No. 2006-015975). Only the rack that moves up and down between the upper (upper) position and the lower (lower) position will be described.

  In addition to the slider 10 (rack 11) described above, the bicycle parking machine 100 is disposed on the support column 12, and has an air cylinder 20 having a piston rod 21 that reciprocates (projects or retracts) in the vertical direction by air pressure, and a piston. A pneumatic control circuit 30 having a switching valve 31 for switching the driving direction of the rod 21; an operation lever 40 (operation means) which is artificially operated by a user or an administrator of the bicycle parking apparatus 100; the piston rod 21 and the slider 10; And a linkage mechanism 50 for connecting the two. That is, the air cylinder 20 has a function of moving the slider 10 (and the rack 11) up and down by the operation of the piston rod 21, and the pneumatic control circuit 30 moves up and down the piston rod 21 and the slider 10 (and the rack 11) of the air cylinder 20. It has a function to control. The switching valve 31 is installed in a fixed state on the column 12, and the operation lever 40 is installed on the bottom side of the rack 11.

  By the way, as shown in FIG. 45, a general bicycle parking facility 1 (bicycle parking lot) has a vertically elevating type bicycle parking machine 100 (FIGS. 1 and 2) in a building having a roofing material 1a, a wall material 1b, a pillar material 1c and the like. A plurality of units (refer to 8 in the example) are installed. An air supply line 3 that forms a circulation loop is connected to the air compressor 2 (air supply source), and the piston rod 21 of each air cylinder 20 is driven and controlled with respect to the loop-shaped air supply line 3. Air pressure control circuits 30 are connected in parallel. Further, on-off valves 4 are provided at the branch points from the air supply pipe 3 to the respective pneumatic control circuits 30. These on-off valves 4 are individually opened and closed in conjunction with a fee collection system 5 that centrally manages a plurality of bicycle parking machines 100 of the bicycle parking facility 1.

  Specifically, the system controller 5a of the fee collection system 5 includes a CPU 5b, a ROM 5c, a RAM 5d, a display unit 5e, a ticket issuing unit 5f, and the like. When a predetermined usage fee is paid by cash, a prepaid card, a credit card, an IC card or the like, the required data is displayed on the display unit 5e, and a receipt and a usage statement are printed and issued by the ticket issuing unit 5f. At the same time, the opening / closing valve 4 of the bicycle parking machine 100 to be used is opened, the air pressure of the air compressor 2 is supplied from the air supply line 3 to the air pressure control circuit 30, and the rack 11 (see FIGS. 1 and 2) is raised and lowered. It becomes possible.

  Thus, by connecting a plurality of pneumatic control circuits 30 in parallel to the loop-shaped air supply pipe 3, the number of installed bicycle parking machines 100 can be adjusted according to the size of the bicycle parking facility 1, and the design -Great flexibility in construction. It is easy to increase the number of bicycle parking machines 100. In addition, by opening and closing the individual opening / closing valves 4 in conjunction with the fee collection system 5, the bicycle parking apparatus 100 can be used simultaneously with the collection of the usage fee. Furthermore, when performing maintenance, inspection, repair, etc. of a specific bicycle parking machine 100, it is only necessary to close the on-off valve 4 necessary for that, and other bicycle parking machines 100 can be used continuously. It is not necessary to close the whole.

  Returning to FIGS. 1 and 2, the linkage mechanism 50 is rotatably supported by the fixed pulley 51 rotatably supported on the upper end portion of the column 12 and the upper end portion (tip portion) of the piston rod 21 that moves up and down. The movable pulley 52 includes a rope 53 having one end fixed to the upper portion of the support column 12, wound around the fixed pulley 51 from the movable pulley 52, and the other end fixed to the upper end of the slider 10.

  As shown in FIG. 1, when the piston rod 21 moves downward and retracts to the lower stroke end (lower limit position) in the cylinder 20, the slider 10 (rack 11) increases by twice the amount of movement of the piston rod 21. Move and stop at the upper stroke end (upper limit position). On the other hand, as shown in FIG. 2, when the piston rod 21 moves upward and protrudes to the upper stroke end (upper limit position) in the cylinder 20, the slider 10 (rack 11) is twice the movement amount of the piston rod 21. Moves down and stops at the lower stroke end (lower limit position). At the lower limit position or upper limit position of the cylinder 20 (piston rod 21), the slider 10 (rack 11) is maintained at the upper limit position or the lower limit position by continuous supply of air pressure and exhaust to the atmosphere. In order to stabilize the operation of the piston rod 21 at the lower limit position and the upper limit position, the pneumatic control circuit 30 is provided with a relief valve, an accumulator, etc. (not shown).

  As described above, by using the linkage mechanism 50 including the movable pulley 52, the vertical movement amount of the slider 10 (or the rack 11) is doubled with respect to the vertical movement amount of the piston rod 21. Accordingly, it is possible to simultaneously increase the lifting / lowering stroke of the rack 11 and compactly assemble the cylinder 20 (particularly the piston rod 21) and the linkage mechanism 50 (particularly the movable pulley 52) to the column 12.

  Next, the peripheral structure of the operation lever 40 will be described with reference to FIGS. An intermediate portion of a swing arm 41 having a rectangular plate shape is pivotally supported around a swing shaft 42 standing on the bottom side of the rack 11. The base end of the rod-shaped operation lever 40 is connected to one end in the longitudinal direction of the swing arm 41 (upper end in FIG. 4) via a lever pin 40a, and the free end (hand operation unit) is in a predetermined direction. (In FIG. 4, it extends in the right direction on the opposite side to the support column 12). A base end portion (one end portion in the longitudinal direction) of the rectangular plate-like operation plate 43 is connected to the other end portion in the longitudinal direction of the swing arm 41 (the lower end portion in FIG. 4) via a plate pin 43a. The tip (the other end in the longitudinal direction) is disposed in the direction opposite to the free end of the swing arm 41. A return spring 44 (tensile coil spring) is stretched between the rack 11 and the swing arm 41.

  As shown in FIGS. 1 and 3, when the rack 11 is stopped at the upper position, the distal end portion of the operating plate 43 faces an upper pilot valve 33U (described later in detail) installed on the upper portion of the column 12. In position. At this time, when the user pulls the free end portion of the operating lever 40 forward, the swing arm 41 rotates, pushes out the operating plate 43, and the tip portion presses the roller 33a of the upper pilot valve 33U to make the machine Operate automatically. 2 and 3, when the rack 11 is in a stopped state at the lower position, the front end of the operating plate 43 is a lower pilot valve 33D (described later in detail) installed at the lower portion of the column 12. It is in the position facing. At this time, when the user pulls the free end portion of the operation lever 40 toward the front, similarly, the tip end portion of the operation plate 43 presses the roller 33a of the lower pilot valve 33D and mechanically operates it.

  Next, the pneumatic circuit diagrams of FIGS. 5 to 10 will be described more specifically. The switching valve 31 shown in these drawings is indirectly controlled through an auxiliary control circuit 32 (auxiliary means) that is operated by operating an operation lever 40 (see FIGS. 3 and 4). 10 and the ascending side control circuit 30U for lowering the piston rod 21 (at this time, the slider 10 and the rack 11 are raised), and the piston rod 21 is raised (at this time, the slider 10). And the rack 11 is switched to the lower side control circuit 30D for lowering. The auxiliary control circuit 32 is branched from the pneumatic control circuit 30 and connected in parallel. The auxiliary control circuit 32 is connected to the upper pilot valve 33U (upper auxiliary switching valve) installed in the upper part of the column 12 and the lower installed in the lower part of the column 12. Side pilot valve 33D (lower auxiliary switching valve).

  More specifically, a 5-port 2-position switching type switching valve 31 is arranged in the pneumatic control circuit 30 that connects the air compressor 2 and the air cylinder 20. A descending side auxiliary control circuit 32D (auxiliary means) for branching from the connection point x of the pneumatic control circuit 30 and directly piloting the switching valve 31 from the outside directly has a three-port two-position switching type upper pilot valve 33U. Is arranged. Similarly, the ascending side auxiliary control circuit 32U (auxiliary means) for branching from the connection point x of the pneumatic control circuit 30 and directly operating the switching valve 31 directly from the outside has a three-port two-position switching type A side pilot valve 33D is arranged. The descending side auxiliary control circuit 32D and the ascending side auxiliary control circuit 32U are connected in parallel to the air pressure control circuit 30, respectively.

  Accordingly, when the state shown in FIGS. 1 and 5 (the rack 11 is stopped at the upper position) is changed to the state shown in FIG. 6, the operation lever 40 mechanically operates the upper pilot valve 33U at the upper part of the column 12, and The switching valve 31 is switched to the lowering side control circuit 30D by the pilot pressure. Specifically, when the upper pilot valve 33U is switched to the position a, the air pressure of the air compressor 2 functions as a pilot pressure that switches the switching valve 31 to the position b through the lowering side auxiliary control circuit 32D. When the switching valve 31 is switched to the position b as shown in FIG. 6, the air pressure of the air compressor 2 is supplied from the lowering side control circuit 30D to the head side of the air cylinder 20, and the piston rod 21 is raised (the rack 11 is lowered). .

  On the other hand, when the state shown in FIGS. 2 and 8 (the rack 11 is stopped at the lower position) is changed to the state shown in FIG. 9, the operation lever 40 mechanically operates the lower pilot valve 33D at the lower portion of the column 12, The switching valve 31 is switched to the ascending control circuit 30U by the pilot pressure. Specifically, when the lower pilot valve 33D is switched to the position a, the air pressure of the air compressor 2 functions as a pilot pressure that switches the switching valve 31 to the position a through the ascending auxiliary control circuit 32U. When the switching valve 31 is switched to the position a as shown in FIG. 9, the air pressure of the air compressor 2 is supplied from the ascending control circuit 30U to the rod side of the air cylinder 20, and the piston rod 21 descends (the rack 11 ascends). .

  Next, the raising / lowering operation | movement of the rack 11 is demonstrated along the order of FIGS.

<The rack 11 is stopped at the upper position> (FIGS. 1 and 5)
Both the upper pilot valve 33U and the lower pilot valve 33D are at the position b, and the pilot pressures of the lower side auxiliary control circuit 32D and the upper side auxiliary control circuit 32U are balanced. Therefore, the switching valve 31 does not change from the position a, and the piston rod 21 is maintained at the lower limit position (the rack 11 is the upper limit position).

<The rack 11 starts to descend at the upper position> (FIG. 6)
When the operation lever 40 is pulled, the operation plate 43 switches the upper pilot valve 33U to the position a. The pilot pressure of the descending side auxiliary control circuit 32D increases, and the switching valve 31 is switched to the b position. The air pressure of the air compressor 2 is supplied from the lowering side control circuit 30D to the head side of the air cylinder 20, and the piston rod 21 starts to rise (the rack 11 is lowered).

<The rack 11 is lowered at the intermediate position> (FIG. 7)
When the operation lever 40 is released, the operation plate 43 is pulled back by the return spring 44, and the upper pilot valve 33U returns to the b position. The pilot pressures of the descending side auxiliary control circuit 32D and the ascending side auxiliary control circuit 32U are balanced again. Therefore, the switching valve 31 does not change from the position b, and the piston rod 21 continues to rise (the rack 11 is lowered).

<The rack 11 is stopped at the lower position> (FIGS. 2 and 8)
Even if the piston rod 21 reaches the upper limit position (the rack 11 is the lower limit position), the upper pilot valve 33U and the lower pilot valve 33D are both in the b position, and the lower side auxiliary control circuit 32D and the higher side auxiliary control circuit 32U Pilot pressure is balanced. Therefore, the switching valve 31 does not change from the b position, and the piston rod 21 is maintained at the upper limit position (the rack 11 is the lower limit position).

<The rack 11 starts to rise at the lower position> (FIG. 9)
When the operation lever 40 is pulled, the operation plate 43 switches the lower pilot valve 33D to the position a. The pilot pressure of the ascending side auxiliary control circuit 32U increases, and the switching valve 31 is switched to the position a. The air pressure of the air compressor 2 is supplied to the rod side of the air cylinder 20 from the ascending side control circuit 30U, and the piston rod 21 starts to descend (the rack 11 rises).

<Rack 11 is lifted at an intermediate position> (FIG. 10)
When the operation lever 40 is released, the operating plate 43 is pulled back by the return spring 44, and the lower pilot valve 33D returns to the b position. The pilot pressures of the descending side auxiliary control circuit 32D and the ascending side auxiliary control circuit 32U are balanced again. Therefore, the switching valve 31 does not fluctuate from the position a, the piston rod 21 continues to descend (the rack 11 rises), and returns to the state of FIG.

  Thus, the pulling operation of the operation lever 40 causes a difference in the pilot pressures of the auxiliary control circuits 32U and 32D, and the switching valve 31 can be mechanically switched. Therefore, the automatic operation of the rack 11 is possible regardless of the actual vehicle state or the empty vehicle state. Easy to move up and down. Further, since the pneumatic control circuit 30, the switching valve 31, the auxiliary control circuits 32U and 32D, and the pilot valves 33U and 33D can all be fixed at fixed positions such as the support column 12, the entire pneumatic circuit can be simply and inexpensively piped.

  In this embodiment, the operation of temporarily stopping the rack 11 (piston rod 21) cannot be performed at an intermediate position (FIGS. 7 and 10) in the middle of raising and lowering. In this way, the operation burden on the user can be further reduced by eliminating the temporary stop operation, the continuous movement operation in the same direction after the temporary stop, and the return movement operation in the reverse direction.

(Example 2)
FIG. 11 is an overall front view when the rack is stopped at the upper position as a second example of the bicycle parking apparatus of the present invention. FIG. 12 is an entire front view when the rack is stopped at the lower position. FIG. 14 is an explanatory diagram of the peripheral structure of the operation lever 40. In the bicycle parking machine 200 of this embodiment, the structure itself of the operation lever 40, the swing arm 41, the swing shaft 42, the operation plate 43, and the return spring 44 is the same as that of the first embodiment (see FIGS. 3 and 4). There is a change in the configuration of the pneumatic control circuit 130, the auxiliary control circuit 132 (auxiliary means), and the pilot valve 133 (auxiliary switching valve).

  As shown in FIGS. 11, 12, and 13, the pilot valve 133 (described later in detail) of the bicycle parking machine 200 is installed in a fixed state at a position facing the tip of the operating plate 43 on the bottom surface side of the rack 11. Has been. Therefore, in this embodiment, regardless of the raising / lowering position of the rack 11, when the user pulls the free end portion of the operation lever 40 toward the front, the tip end portion of the operating plate 43 presses the roller 133a of the pilot valve 133. Operate automatically. As the pilot valve 133 is installed in the rack 11 that moves up and down, the pneumatic control circuit 130 and the auxiliary control circuit 132 are formed of a flexible tube that can be expanded and contracted.

  Next, the pneumatic circuit diagrams of FIGS. 15 to 20 will be described. The switching valve 31 shown in these drawings is indirectly controlled through an auxiliary control circuit 132 (auxiliary means) that is operated by operating the operation lever 40 (see FIGS. 13 and 14). The auxiliary control circuit 132 is branched from the connection point x of the pneumatic control circuit 30 and connected in parallel. The auxiliary control circuit 132 has a single pilot valve 133 (auxiliary switching valve) installed in the rack 11 in a fixed state. ) Is arranged. The pilot valve 133 is a 5-port 2-position switching type and has a detent for holding each switching position, and an outlet port of the pilot valve 133 is an ascending auxiliary control circuit 132U for directly piloting the switching valve 31 from the outside. (Auxiliary means) and a descending side auxiliary control circuit 132D (auxiliary means). Each time the operating lever 40 is operated, the pilot valve 133 is mechanically operated, and the switching valve 31 is alternately switched between the ascending-side control circuit 132U and the descending-side control circuit 132D by the pilot pressure.

  Therefore, when the state shown in FIGS. 11 and 15 (the rack 11 is stopped at the upper position) is changed to the state shown in FIG. 16, the operation lever 40 switches the pilot valve 133 to the position a on the bottom surface of the rack 11 The switching valve 31 is switched to the lowering side control circuit 30D by the pilot pressure of the control circuit 132D. Specifically, when the pilot valve 133 is switched to the a position, the air pressure of the air compressor 2 functions as a pilot pressure that switches the switching valve 31 to the b position through the descending auxiliary control circuit 132D. When the switching valve 31 is switched to the position b as shown in FIG. 16, the air pressure of the air compressor 2 is supplied from the lowering side control circuit 30D to the head side of the air cylinder 20, and the piston rod 21 is raised (the rack 11 is lowered). .

  On the other hand, when the state shown in FIGS. 12 and 18 (the rack 11 is stopped at the lower position) is changed to the state shown in FIG. 19, the operation lever 40 switches the pilot valve 133 to the b position on the bottom surface of the rack 11 The switching valve 31 is switched to the ascending side control circuit 30U by the pilot pressure of the control circuit 132U. Specifically, when the pilot valve 133D is switched to the b position, the air pressure of the air compressor 2 functions as a pilot pressure that passes through the ascending auxiliary control circuit 132U and switches the switching valve 31 to the a position. When the switching valve 31 is switched to the position a as shown in FIG. 19, the air pressure of the air compressor 2 is supplied from the ascending side control circuit 30U to the rod side of the air cylinder 20, and the piston rod 21 is lowered (the rack 11 is raised). .

  Next, the raising / lowering operation | movement of the rack 11 is demonstrated along the order of FIGS.

<The rack 11 is stopped at the upper position> (FIGS. 11 and 15)
The pilot valve 133 is in the b position, and the pilot pressure of the ascending auxiliary control circuit 132U is maintained high. Therefore, the switching valve 31 does not change from the position a, and the piston rod 21 is maintained at the lower limit position (the rack 11 is the upper limit position).

<The rack 11 starts to descend at the upper position> (FIG. 16)
When the operation lever 40 is pulled, the operation plate 43 switches the pilot valve 133 to the position a. The pilot pressure of the descending side auxiliary control circuit 132D increases, and the switching valve 31 is switched to the b position. The air pressure of the air compressor 2 is supplied from the lowering side control circuit 30D to the head side of the air cylinder 20, and the piston rod 21 starts to rise (the rack 11 is lowered).

<The rack 11 is lowered at the intermediate position> (FIG. 17)
When the operation lever 40 is released, the operating plate 43 is pulled back by the return spring 44, but the pilot valve 133 maintains the position a by detent. Since the pilot pressure of the descending auxiliary control circuit 132D is high, the switching valve 31 does not change from the position b, and the piston rod 21 continues to rise (the rack 11 descends).

<The rack 11 is stopped at the lower position> (FIGS. 12 and 18)
Even if the piston rod 21 reaches the upper limit position (the rack 11 is the lower limit position), the pilot valve 133 is in the position a, and the pilot pressure of the descending auxiliary control circuit 132D is maintained high. Therefore, the switching valve 31 does not change from the b position, and the piston rod 21 is maintained at the upper limit position (the rack 11 is the lower limit position).

<The rack 11 starts to rise at the lower position> (FIG. 19)
When the operation lever 40 is pulled, the operation plate 43 switches the pilot valve 133 to the b position. The pilot pressure of the ascending side auxiliary control circuit 132U increases, and the switching valve 31 is switched to the position a. The air pressure of the air compressor 2 is supplied to the rod side of the air cylinder 20 from the ascending side control circuit 30U, and the piston rod 21 starts to descend (the rack 11 rises).

<Rack 11 is lifted at an intermediate position> (FIG. 20)
When the operation lever 40 is released, the operating plate 43 is pulled back by the return spring 44, but the pilot valve 133 maintains the position b by detent. Since the pilot pressure of the ascending side auxiliary control circuit 132U is high, the switching valve 31 does not change from the position a, the piston rod 21 continues to descend (the rack 11 rises), and returns to the state of FIG.

  Thus, the pulling operation of the operation lever 40 causes a difference in the pilot pressures of the auxiliary control circuits 132U and 132D, and the switching valve 31 can be mechanically switched. Therefore, the automatic operation of the rack 11 is possible regardless of the actual vehicle state or the empty vehicle state. Easy to move up and down. Further, the pilot valve 133 installed in the rack 11 is shared by the ascending side control circuit 30U and the descending side control circuit 30D, thereby simplifying the pneumatic control circuit 30.

  In this embodiment, the operation of temporarily stopping the rack 11 (piston rod 21) at the intermediate position (FIGS. 17 and 20) in the middle of raising and lowering and the continuous movement operation in the same direction after the temporary stop cannot be performed. Switching operation in the ascending / descending direction at the position (FIGS. 15 to 20) (reverse movement operation in the reverse direction) is possible. For example, when the operating lever 40 is pulled in the state of FIG. 17, the state immediately becomes the state of FIG. 20 (without passing through FIGS. 18 and 19), and when the operating lever 40 is pulled in the state of FIG. The state of FIG. 17 is immediately obtained (without passing 16).

Example 3
FIG. 21 is an overall front view when the rack starts to descend at the upper position as a third example of the bicycle parking apparatus of the present invention, and FIG. 22 is an entire front view when the rack starts to rise at the lower position. In the bicycle parking apparatus 300 of this embodiment, the configuration of the switching valves 231U and 231D and the operation piece 240 is changed from that of the first embodiment.

  As shown in FIGS. 21 and 22, an ascending-side switching valve 231U (switching valve) disposed in the ascending-side control circuit 30U and a descending-side switching valve 231D (switching valve) disposed in the descending-side control circuit 30D are parked. It is installed in a fixed state on the pillar material 1c of the wheel facility 1 (bicycle parking lot). A plate-like operation piece 240 (operation means) for mechanically switching the switching valves 231U and 231D is installed in the vicinity of the switching valves 231U and 231D. These switching valves 231U and 231D are switched to the ascending side control circuit 30U or the descending side control circuit 30D according to the operation of the operation piece 240. The operation piece 240 also serves as a display unit for displaying the operation status.

  Next, the pneumatic circuit diagram of FIGS. 23 to 28 will be described. The ascending-side switching valve 231U disposed in the ascending-side control circuit 30U and the descending-side switching valve 231D disposed in the descending-side control circuit 30D are simultaneously operated by the operation piece 240. The ascending side switching valve 231U and the descending side switching valve 231D are of the 5-port 2-position switching type and have detents that hold the respective switching positions, and their outlet ports are connected to the ascending side control circuit 30U and the descending side control circuit 30D. Connected in parallel. Further, every time the operation piece 240 is operated, the ascending side switching valve 231U alternately switches between a state where the ascending side control circuit 30U is operated and a state where the descending side switching valve 231D operates the descending side control circuit 30D. . That is, by operating the operation piece 240, the ascending side control circuit 30U is activated and the descending side control circuit 30D is not activated via the ascending side switching valve 231U and the descending side switching valve 231D (see FIGS. 27 and 28). ), And the rising side control circuit 30U is inoperative and the falling side control circuit 30D is alternately switched (see FIGS. 24 and 25).

  Next, the raising / lowering operation | movement of the rack 11 is demonstrated along the order of FIGS.

<The rack 11 is stopped at the upper position> (FIG. 23)
The ascending side switching valve 231U and the descending side switching valve 231D are both at the position b, and the ascending side control circuit 30U is in the activated state and the descending side control circuit 30D is in the inoperative state. Therefore, the piston rod 21 is maintained at the lower limit position (the rack 11 is the upper limit position), and “rack rise” is displayed on the operation piece 240.

<Rack 11 starts descending at upper position> (FIGS. 21 and 24)
Since the push button 231a of the ascending side switching valve 231U and the descending side switching valve 231D is simultaneously pressed by the pressing operation of the operation piece 240, both the switching valves 231U and 231D are switched to the a position, so that the ascending side control circuit 30U is inactive. Thus, the lowering side control circuit 30D is activated. The air pressure of the air compressor 2 is supplied from the lowering control circuit 30D to the head side of the air cylinder 20, the piston rod 21 starts to rise (the rack 11 is lowered), and the operation piece 240 displays "rack lowering". .

<The rack 11 is lowered at the intermediate position> (FIG. 25)
Even if the operation piece 240 is not pressed, both the switching valves 231U and 231D maintain the position a by detent. There is no change in the operating state of the ascending side control circuit 30U and the descending side control circuit 30D, the piston rod 21 continues to rise (the rack 11 is lowered), and the operation piece 240 continues to be “rack lowered”. Is displayed.

<The rack 11 is stopped at the lower position> (FIG. 26)
Even when the piston rod 21 reaches the upper limit position (the rack 11 is the lower limit position), the ascending side control circuit 30U is not operated and the descending side control circuit 30D is not changed in operating state. Therefore, the piston rod 21 is maintained at the upper limit position (the rack 11 is the lower limit position), and the “rack down” display of the operation piece 240 is also maintained as it is.

<The rack 11 starts to rise at the lower position> (FIGS. 22 and 27)
The push button 231a of the ascending side switching valve 231U and the descending side switching valve 231D is simultaneously pressed by the pressing operation of the operation piece 240, and both the switching valves 231U and 231D are switched to the b position. The descending side control circuit 30D is inactivated. The air pressure of the air compressor 2 is supplied to the rod side of the air cylinder 20 from the ascending-side control circuit 30U, the piston rod 21 starts to descend (the rack 11 rises), and “rack up” is displayed on the operation piece 240. .

<Rack 11 is lifted at an intermediate position> (FIG. 28)
Even if the operation piece 240 is not pressed, both the switching valves 231U and 231D maintain the position b by detent. There is no change between the ascending control circuit 30U and the descending control circuit 30D being inactive, the piston rod 21 continues to descend (the rack 11 rises), and the operation piece 240 continues to “rack rise”. The display is returned to the state shown in FIG.

  Thus, since both the switching valves 231U and 231D are installed on the pillar material 1c of the bicycle parking facility 1, and the operation piece 240 is disposed in the vicinity of the both switching valves 231U and 231D, the ascending side control circuit 30U and the descending side control are controlled. The switching of the circuit 30D can be quickly performed by the operation piece 240, and the switching state can be displayed on the operation piece 240 itself.

  In this embodiment, the operation of temporarily stopping the rack 11 (piston rod 21) at the intermediate position (FIGS. 25 and 28) in the middle of raising and lowering and the continuous movement operation in the same direction after the temporary stop cannot be performed. Switching operation in the ascending / descending direction at the position (FIGS. 23 to 28) (reverse movement operation in the reverse direction) is possible. For example, when the operation piece 240 is pressed in the state of FIG. 25 (without passing through FIGS. 26 and 27), the state immediately becomes the state of FIG. 28, and when the operation piece 240 is pressed in the state of FIG. The state of FIG. 25 is immediately obtained (without 24).

Example 4
FIG. 29 is an overall front view when the rack starts to descend at the upper position as a fourth example of the bicycle parking apparatus of the present invention, and FIG. 30 is an entire front view when the rack starts to rise at the lower position. In the bicycle parking machine 400 of this embodiment, the configuration of the switching valve 331, the stop valve 332, the operation piece 341, and the on / off operation piece 342 is changed from the third embodiment.

  As shown in FIGS. 29 and 30, the switching valve 331 disposed in the ascending side control circuit 30 </ b> U and the descending side control circuit 30 </ b> D is installed in a fixed state on the pillar material 1 c of the bicycle parking facility 1 (bicycle parking lot). A plate-shaped operation piece 341 (operation means) for mechanically switching the switching valve 331 is installed in the vicinity of the switching valve 331. The switching valve 331 is switched to the ascending side control circuit 30U or the descending side control circuit 30D according to the operation of the operation piece 341.

  Next, the pneumatic circuit diagrams of FIGS. 31 to 36 will be described. A stop valve 332 (stop valve) common to the ascending side control circuit 30U and the descending side control circuit 30D is connected in series with the switching valve 331 in the pneumatic control circuit 30. The stop valve 332 opens and closes the pneumatic control circuit 30 based on the operation of the on / off operation piece 342 regardless of the switching of the switching valve 331 based on the operation of the operation piece 341. The switching valve 331 is a 5-port 2-position switching type and has a detent for holding each switching position. The stop valve 332 is a 2-port 2-position switching type and has a detent for holding each switching position. Note that the operation piece 341 and the on / off operation piece 342 also serve as a display unit for displaying the operation status.

  Next, the raising / lowering operation | movement of the rack 11 is demonstrated along the order of FIGS.

<The rack 11 is stopped at the upper position> (FIG. 31)
When the rack 11 is in the upper position, when the push button 332a of the stop valve 332 is pressed by the pressing operation of the on / off operation piece 342, the stop valve 332 is switched to the b position (regardless of the switching position of the switching valve 331). The pneumatic control circuit 30 is closed (disconnected) by the stop valve 332. Therefore, the piston rod 21 is maintained at the lower limit position (the rack 11 is the upper limit position), and “up” is displayed on the operation piece 341, and “rack stop” is displayed on the on / off operation piece 342.

<The rack 11 starts to descend at the upper position> (FIGS. 29 and 32)
When the push button 332a of the stop valve 332 is pressed by the pressing operation of the on / off operation piece 342, the stop valve 332 is switched to the position a, and the pneumatic control circuit 30 is opened (communication state) by the stop valve 332. Further, when the push button 331 a of the switching valve 331 is pushed by the pressing operation of the operation piece 341, the switching valve 331 is switched to the “a” position, and the lowering control circuit 30 D is operated in the pneumatic control circuit 30. The air pressure of the air compressor 2 is supplied from the lower side control circuit 30D to the head side of the air cylinder 20, the piston rod 21 starts to rise (the rack 11 is lowered), the operation piece 341 is "down", and the on / off operation piece “Move rack” is displayed on each 342. The operation order of the operation piece 341 and the on / off operation piece 342 is not limited.

<The rack 11 is lowered at the intermediate position> (FIG. 33)
Even if the operation piece 341 and the on / off operation piece 342 are not pressed, both the switching valve 331 and the stop valve 332 maintain the position a by detent. There is no change in the state in which the lowering control circuit 30D is operated in the pneumatic control circuit 30, the piston rod 21 continues to rise (the rack 11 is lowered), the operation piece 341 is "down", and the on / off operation piece 342 is changed. Will continue to display “Move Rack”.

<The rack 11 is stopped at the lower position> (FIG. 34)
When the rack 11 reaches the lower position, when the push button 332a of the stop valve 332 is pressed by the pressing operation of the on / off operation piece 342, the stop valve 332 is switched to the b position (What is the switching position of the switching valve 331? Regardless) the pneumatic control circuit 30 is closed (disconnected) by a stop valve 332. Accordingly, the piston rod 21 is maintained at the upper limit position (the rack 11 is at the lower limit position), “down” is displayed on the operation piece 341, and “rack stop” is displayed on the on / off operation piece 342.

<The rack 11 starts to rise at the lower position> (FIGS. 30 and 35)
When the push button 332a of the stop valve 332 is pressed by the pressing operation of the on / off operation piece 342, the stop valve 332 is switched to the position a, and the pneumatic control circuit 30 is opened (communication state) by the stop valve 332. Further, when the push button 331 a of the switching valve 331 is pushed by the pressing operation of the operation piece 341, the switching valve 331 is switched to the b position, and the ascending side control circuit 30 U is operated in the air pressure control circuit 30. The air pressure of the air compressor 2 is supplied from the ascending-side control circuit 30U to the rod side of the air cylinder 20, and the piston rod 21 starts to descend (the rack 11 is ascending). “Move rack” is displayed on each 342. The operation order of the operation piece 341 and the on / off operation piece 342 is not limited.

<Rack 11 is in an elevated state at an intermediate position> (FIG. 36)
Even if the operation piece 341 is not pressed, the switching valve 331 maintains the position b by detent. Similarly, even if the on / off operation piece 342 is no longer pressed, the stop valve 332 maintains the position a. Therefore, there is no change in the operating state of the ascending control circuit 30U in the air pressure control circuit 30, the piston rod 21 continues to descend (the rack 11 is ascending), the operation piece 341 is "raised", and the on / off operation piece “Move rack” is continuously displayed in 342, and the state returns to the state of FIG.

  Thus, since the switching valve 331 is installed in the pillar 1c of the bicycle parking facility 1 and the operation piece 341 is disposed in the vicinity of the switching valve 331, the switching between the ascending control circuit 30U and the descending control circuit 30D is operated. The operation can be quickly performed by the piece 341, and the switching state can be displayed on the operation piece 341 itself.

  In this embodiment, the operation of temporarily stopping the rack 11 (piston rod 21), the continuous movement operation in the same direction after the stop, and the reverse direction are performed at any position (FIGS. 31 to 36) during ascending and descending. Return movement operation (switching operation in the up-and-down direction) is possible, and an emergency stop can be performed for each vehicle by the user.

(Example 5)
FIG. 37 is an overall front view when the rack starts to descend at the upper position, and FIG. 38 is an overall front view when the rack starts to rise at the lower position, as a fifth example of the bicycle parking apparatus of the present invention. In the bicycle parking apparatus 500 of this embodiment, the configuration of the electromagnetic switching valve 431, the remote controller 432, the operation switches 441 and 442, and the on / off operation switch 443 is changed from the third embodiment.

  As shown in FIGS. 37 and 38, the control signal (auxiliary means) of the remote controller 432 (remote controller) in which the electromagnetic switching valve 431 arranged in the pneumatic control circuit 30 is activated by the operation of the operation switches 441 and 442 (operating means). ) To indirectly switch to the ascending side control circuit 30U and the descending side control circuit 30D. Note that the remote controller 432 uses a transmission / reception function of a wireless communication device, a mobile terminal (including a mobile phone), or the like.

  Next, the pneumatic circuit diagrams of FIGS. 39 to 44 will be described. The electromagnetic switching valve 431 disposed in the pneumatic control circuit 30 is a double-acting 5-port 3-position switching type. The electromagnetic switching valve 431 is switched to the position a by the pressing operation of the first operation switch 441 (operation means) provided on the remote controller 432, and the ascending side control circuit 30U is activated (see FIGS. 43 and 44). On the other hand, when the second operation switch 442 (operation means) is pressed, the position is switched to the position c, and the lowering control circuit 30D is activated (see FIGS. 40 and 41). Further, the electromagnetic switching valve 431 is switched to the position c by the pressing operation of the on / off operation switch 443 provided in the remote controller 432, and the pneumatic control circuit 30 is closed (disconnected state). The operation switches 441 and 442 and the on / off operation switch 443 also serve as a display unit for lighting and displaying the operation status.

  Next, the raising / lowering operation | movement of the rack 11 is demonstrated along the order of FIGS.

<The rack 11 is stopped at the upper position> (FIG. 39)
If the on / off operation switch 443 is pressed when the rack 11 is in the upper position, the electromagnetic switching valve 431 is switched to the b position via the control signal of the remote controller 432, and the pneumatic control circuit 30 is closed (disconnected state). Is done. Therefore, the piston rod 21 is maintained at the lower limit position (rack 11 is the upper limit position), and “rack stop” is lit on the on / off operation switch 443.

<The rack 11 starts to descend at the upper position> (FIGS. 37 and 40)
When the second operation switch 442 is pressed, the electromagnetic switching valve 431 is switched to the position c via the control signal of the remote controller 432, and the lowering control circuit 30D is activated in the pneumatic control circuit 30. The air pressure of the air compressor 2 is supplied from the lower side control circuit 30D to the head side of the air cylinder 20, the piston rod 21 starts to rise (the rack 11 is lowered), and the second operation switch 442 has "rack down". Lights up.

<The rack 11 is lowered at the intermediate position> (FIG. 41)
Even when the second operation switch 442 is not pressed, the electromagnetic switching valve 431 maintains the c position by the control signal of the remote controller 432. There is no change in the operating state of the lowering control circuit 30D in the pneumatic control circuit 30, the piston rod 21 continues to rise (the rack 11 is lowered), and “rack down” continues to light on the second operation switch 442. Is displayed.

<The rack 11 is stopped at the lower position> (FIG. 42)
When the rack 11 reaches the lower position and the on / off operation switch 443 is pressed, the electromagnetic switching valve 431 is switched to the position b via the control signal of the remote controller 432, and the pneumatic control circuit 30 is closed (disconnected state). ) Therefore, the piston rod 21 is maintained at the upper limit position (rack 11 is the lower limit position), and “rack stop” is lit on the on / off operation switch 443.

<The rack 11 starts to rise at the lower position> (FIGS. 38 and 43)
When the first operation switch 441 is pressed, the electromagnetic switching valve 431 is switched to the position a via the control signal of the remote controller 432, and the ascending side control circuit 30U is activated in the pneumatic control circuit 30. The air pressure of the air compressor 2 is supplied from the ascending-side control circuit 30U to the rod side of the air cylinder 20, the piston rod 21 starts to descend (the rack 11 is ascending), and the first operation switch 441 displays “rack ascending”. Lights up.

<The rack 11 is raised at the intermediate position> (FIG. 44)
Even when the first operation switch 441 is not pressed, the electromagnetic switching valve 431 maintains the position a by the control signal of the remote controller 432. There is no change in the operating state of the ascending control circuit 30U in the air pressure control circuit 30, the piston rod 21 continues to descend (the rack 11 rises), and the first operation switch 441 continues to light “rack up”. The display is returned to the state shown in FIG.

  In this way, the ascending control circuit 30U and the descending control circuit 30D can be quickly switched by the operation switches 441 and 442 of the remote controller 432, and the switching state can be displayed on the operation switches 441 and 442 themselves.

  In this embodiment, at an arbitrary position during lifting (FIGS. 39 to 44), an operation of temporarily stopping the rack 11 (piston rod 21), a continuous movement operation in the same direction after the stop, and a reverse direction. Return movement operation (switching operation in the up-and-down direction) is possible, and an emergency stop can be performed for each vehicle by the user.

  In the above description, it is assumed that the vertical elevating bicycle parking machine has two upper and lower racks and includes the linkage mechanism 50 including the movable pulley 52 and the rope 53. However, the present invention is based on such a method. It is not limited to.
